"Description of Junior Subordinated Debentures -- General." Although the
Company, as a savings and loan holding company, is not subject to the Federal
Reserve capital requirements for bank holding companies, it is possible that in
the future it could become subject to such requirements as a result of the
acquisition of a bank, a change in applicable regulations or the Company
otherwise becoming subject to Federal Reserve capital requirements. The Capital
Securities will have a preference under certain circumstances over the Common
Securities with respect to cash distributions and amounts payable on
liquidation, redemption or otherwise. See "Description of Capital
Securities -- Subordination of Common Securities."
    
 
   
     Holders of the Capital Securities will be entitled to receive preferential
cumulative cash distributions accumulating from the date of original issuance
and payable quarterly in arrears on September 30, December 31, March 31 and June
30 of each year, commencing September 30, 1997, at the annual rate of     % of
the Liquidation Amount of $25 per Capital Security ("Distributions"). The amount
of each Distribution due with respect to the Capital Securities will include
amounts accrued through the date the distribution payment is due. The Company
has the right to defer payment of interest on the Junior Subordinated Debentures
at any time or from time to time for a period not exceeding 20 consecutive
quarterly periods with respect to each deferral period (each, an "Extension
Period"), provided that no Extension Period may extend beyond the Stated
Maturity of the Junior Subordinated Debentures. No interest shall be due and
payable during any Extension Period, except at the end thereof. 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 Junior Subordinated
Debentures are so deferred, Distributions on the Capital 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 the
Company's capital stock or with respect to debt securities of the Company that
rank pari passu in all respects with or junior to the Junior Subordinated
Debentures. During an Extension Period, interest on the Junior Subordinated
Debentures will continue to accrue (and the amount of Distributions to which
holders of the Capital Securities are entitled will accumulate) at the rate
of     % per annum, compounded quarterly, and holders of Capital Securities will
be required to accrue income for United States federal income tax purposes. See
"Description of Junior Subordinated Debentures -- Option to Extend Interest
Payment Period" and "Certain Federal Income Tax Consequences -- US
Holders -- Interest Income and Original Issue Discount."
    
 
   
     The Company has, through the Guarantee, the Trust Agreement, the Junior
Subordinated Debentures and the Junior Subordinated Indenture (each as defined
herein), taken together, fully, irrevocably and unconditionally guaranteed all
Sterling Capital's obligations under the Capital Securities as described below.
See "Relationship Among the Capital Securities, the Junior Subordinated
Debentures and the Guarantee -- Full and Unconditional Guarantee." Under the
Guarantee, the Company guarantees the payment of Distributions and payments on
liquidation or redemption of the Capital Securities, but only in each case to
the extent of funds held by Sterling Capital, as described herein. See
"Description of Guarantee." If the Company does not make payments on the Junior
Subordinated Debentures held by Sterling Capital, Sterling Capital may have
insufficient funds to pay Distributions on the Capital Securities. The Guarantee
does not cover payment of Distributions when Sterling Capital does not have
sufficient funds to pay such Distributions. In such event, a holder of Capital
Securities may institute a legal proceeding directly against the Company to
enforce payment of such Distributions to such holder. See "Description of Junior
Subordinated Debentures -- Enforcement of Certain Rights by Holders of Capital
Securities." The obligations of the Company under the Guarantee and the Capital
Securities are subordinate and junior in right of payment to all Senior
Indebtedness (as defined in "Description of Junior Subordinated
Debentures -- Subordination") of the Company.
    
 
   
     The Capital Securities are subject to mandatory redemption (i) in whole,
but not in part, upon repayment of the Junior Subordinated Debentures at Stated
Maturity or their earlier optional redemption in whole upon the occurrence of a
Tax Event, an Investment Company Event or a Capital Treatment Event (each as
defined herein) and (ii) in whole or in part at any time on or after
  , 2002 contemporaneously with the optional redemption by the Company of the
Junior Subordinated Debentures in whole or in part. The Junior

(cover page continued)
 
Subordinated Debentures are redeemable prior to maturity at the option of the
Company (i) on or after             , 2002, in whole at any time or in part from
time to time, or (ii) in whole, but not in part, at any time within 90 days
following the occurrence and continuation of a Tax Event, Investment Company
Event or Capital Treatment Event, in each case at a redemption price equal to
the accrued and unpaid interest on the Junior Subordinated Debentures so
redeemed to but excluding the date fixed for redemption plus 100% of the
principal amount thereof. See "Description of Junior Subordinated
Debentures -- Redemption."
 
   
     The holders of the outstanding Common Securities will have the right at any
time to dissolve Sterling Capital and, after satisfaction of liabilities to
creditors of Sterling Capital as provided by applicable law, to cause the Junior
Subordinated Debentures to be distributed to the holders of the Capital
Securities and Common Securities in liquidation of Sterling Capital. The ability
of the Company to dissolve Sterling Capital may be subject to prior regulatory
approval of the Federal Reserve. See "Description of Capital Securities --
Liquidation Distribution Upon Dissolution."
    
 
     In the event of the dissolution of Sterling Capital, after satisfaction of
liabilities to creditors of Sterling Capital as provided by applicable law, the
holders of the Capital Securities will be entitled to receive a Liquidation
Amount of $25 per Capital Security plus accumulated and unpaid Distributions
thereon to the date of payment, subject to certain exceptions, which may be in
the form of a distribution of such amount in Junior Subordinated Debentures. See
"Description of Capital Securities -- Liquidation Distribution Upon
Dissolution."
 
     The Junior Subordinated Debentures are unsecured and subordinated to all
Senior Indebtedness of the Company. As of March 31, 1997, the Company had
approximately $32.2 million of Senior Indebtedness outstanding. See "Description
of Junior Subordinated Debentures -- Subordination."
 
   
     An application has been made to include the Capital Securities for listing
on the Nasdaq National Market. Although each of the Underwriters has indicated
an intention to make a market in the Capital Securities, the Underwriters are
not obligated to do so, and any market making may be discontinued at any time at
the sole discretion of such Underwriters. There can be no assurance that a
market will develop for the Capital Securities. See "Risk Factors -- Absence of
Existing Public Market; Market Prices" and "Underwriting."
    
 
   
     The Capital Securities will be represented by one or more global
certificates registered in the name of The Depository Trust Company ("DTC") or
its nominee. Beneficial interests in the Capital Securities will be shown on,
and transfers thereof will be effected only through, records maintained by
participants in DTC. Except as described herein, the Capital Securities in
certificate form will not be issued in exchange for global certificates. See
"Description of Capital Securities -- Book-Entry, Delivery and Form."
    
 
     Prospective purchasers must carefully consider the information set forth in
"Certain ERISA Considerations."
 
     THE JUNIOR SUBORDINATED DEBENTURES ARE DIRECT AND UNSECURED OBLIGATIONS OF
THE COMPANY, DO NOT EVIDENCE DEPOSITS AND ARE NOT INSURED BY THE FEDERAL DEPOSIT
INSURANCE CORPORATION OR ANY OTHER INSURER OR GOVERNMENTAL AGENCY.
 
     As used herein, (i) the "Junior Subordinated Indenture" means the Junior

                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and financial statements and notes thereto appearing elsewhere in
this Prospectus or in the documents incorporated into this Prospectus by
reference. Unless the context clearly suggests otherwise, references to the
Company include the Company and its subsidiaries.
 
                         STERLING FINANCIAL CORPORATION
 
     The Company is a unitary savings and loan holding company, the significant
operating subsidiary of which is Sterling Savings Association ("Sterling
Savings"). The principal operating subsidiaries of Sterling Savings are Action
Mortgage Company ("Action Mortgage"), INTERVEST-Mortgage Investment Company
("INTERVEST") and Harbor Financial Services, Inc. ("Harbor Financial"). Sterling
Savings commenced operations in 1983 as a State of Washington-chartered,
federally-insured stock savings and loan association headquartered in Spokane,
Washington. Since 1983, Sterling has made a number of acquisitions to expand its
retail branch delivery system, to add deposits and earning assets and to
geographically diversify its loan portfolio. Sterling Savings attracts Federal
Deposit Insurance Corporation ("FDIC") insured deposits through 41 retail
branches located primarily in rural and suburban communities in Washington and
Oregon. The Company originates loans through its branch offices as well as 10
Action Mortgage residential loan production offices in the Spokane and Seattle,
Washington; Portland, Oregon and Boise, Idaho metropolitan areas and three
INTERVEST commercial real estate lending offices located in the metropolitan
areas of Seattle, Spokane and Portland. The Company also markets tax-deferred
annuities, mutual funds and other financial products through Harbor Financial.
 
     Sterling Savings' revenues are derived primarily from interest earned on
loans and mortgage-backed securities, from fees and service charges and from
mortgage banking operations. The Company provides personalized, quality
financial services to its customers as exemplified by its "Hometown Helpful"
philosophy. The Company believes this dedication to personalized service has
enabled it to maintain a stable and relatively low-cost retail deposit base in
rural areas, while generating a substantial volume of lending activity primarily
in the metropolitan areas of the Pacific Northwest. In recent years, Sterling
Savings has focused its efforts on becoming more like a community retail bank by
increasing its construction, business banking and consumer lending while placing
an increased emphasis on attracting greater volumes of retail deposits. The
Company maintains its principal executive offices at 111 North Wall Street,
Spokane, Washington 99201, telephone number (509) 358-6160.
 
                            STERLING CAPITAL TRUST I
 
     Sterling Capital is a statutory business trust created under Delaware law
pursuant to the filing of a certificate of trust with the Delaware Secretary of
State on May 5, 1997. Sterling Capital will be governed by an Amended and
Restated Trust Agreement among the Company, as Depositor, Bankers Trust
(Delaware), as Delaware Trustee, and Bankers Trust Company, as Property Trustee.
Two individuals will be selected by the holders of the Common Securities to act
as administrators with respect to Sterling Capital (the "Administrators"). The
Company, while holder of the Common Securities, intends to select two
individuals who are employees or officers of or affiliated with the Company to
serve as the Administrators. See "Description of Capital
Securities -- Miscellaneous." Sterling Capital exists for the exclusive purposes
of (i) issuing and selling the Trust Securities, (ii) using the proceeds from
the sale of the Trust Securities to acquire the Junior Subordinated Debentures
and (iii) engaging in only those other activities necessary, convenient or
incidental thereto (such as registering the transfer of the Trust Securities).
Accordingly, the Junior Subordinated Debentures will be the sole assets of
Sterling Capital, and payments under the Junior Subordinated Debentures will be
the sole source of revenue of Sterling Capital.
 
     All the Common Securities will initially be owned by the Company. The
Common Securities will rank pari passu, and payments will be made thereon pro
rata, with the Capital Securities, except that upon the occurrence and during
the continuation of a Debenture Event of Default arising as a result of any
failure by
 
                                        6

the Company to pay any amounts in respect of the Junior Subordinated Debentures
when due, the rights of the holders 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 Capital Securities. See
"Description of Capital Securities -- Subordination of Common Securities." The
Company will acquire Common Securities in an aggregate liquidation amount equal
to 3% of the total capital of Sterling Capital. Sterling Capital has a term of
31 years, but may terminate earlier as provided in the Trust Agreement. The
address of Sterling Capital is 111 North Wall Street, Spokane, Washington 99201,
telephone number (509) 358-6160.
 
                                  THE OFFERING
 
Capital Securities Issuer....  Sterling Capital.
 
Securities Offered...........  1,600,000 Capital Securities. The Capital
                               Securities represent undivided beneficial
                               interests in Sterling Capital's assets, which
                               will consist solely of Junior Subordinated
                               Debentures and payments thereunder.
 
Distributions................  The Distributions payable on each Capital
                               Security will be fixed at a rate per annum
                               of     % of the Liquidation Amount of $25 per
                               Capital Security, will be cumulative, will accrue
                               from the date of issuance of the Capital
                               Securities, and will be payable quarterly in
                               arrears on the last day of September, December,
                               March and June of each year, commencing on
                               September 30, 1997 (subject to possible deferral
                               as described below). The amount of each
                               distribution due with respect to the Capital
                               Securities will include amounts accrued through
                               the date the distribution payment is due. See
                               "Description of Capital
                               Securities -- Distributions."
 
Extension Periods............  So long as no Debenture Event of Default (as
                               defined herein) has occurred and is continuing,
                               the Company will have the right, at any time, to
                               defer payments of interest on the Junior
                               Subordinated Debentures by extending the interest
                               payment period thereon for a period not exceeding
                               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 Junior
                               Subordinated Debentures. If interest payments are
                               so deferred, Distributions on the Capital
                               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 the
                               Company's capital stock or debt securities that
                               rank pari passu with or junior to the Junior
                               Subordinated Debentures. During an Extension
                               Period, Distributions will continue to accrue
                               with income thereon compounded quarterly. Because
                               interest will continue to accrue and compound on
                               the Junior Subordinated Debentures, to the extent
                               permitted by applicable law, holders of the
                               Capital Securities will be required to accrue
                               income for United States federal income tax
                               purposes. See "Description of Junior Subordinated
                               Debentures -- Option to Extend Interest Payment
                               Period" and "Certain Federal Income Tax
                               Consequences -- US Holders -- Interest Income and
                               Original Issue Discount."
 
Maturity.....................  The Junior Subordinated Debentures will mature on
                                           , 2027, which date may be shortened
                               (such date, as it may be shortened, the "Stated
                               Maturity") to a date not earlier than

                               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).
 
Redemption...................  The Capital Securities are subject to mandatory
                               redemption upon repayment of the Junior
                               Subordinated Debentures at maturity or their
                               earlier redemption in an amount equal to the
                               amount of Junior Subordinated Debentures maturing
                               or being redeemed at a redemption price equal to
                               the aggregate Liquidation Amount of the Capital
                               Securities, plus accumulated and unpaid
                               Distributions thereon to the date of redemption.
                               Subject to Federal Reserve approval, if then
                               required under applicable capital guidelines or
                               policies of the Federal Reserve, the Junior
                               Subordinated Debentures are redeemable prior to
                               maturity at the option of the Company (i) on or
                               after             , 2002, in whole at any time or
                               in part from time to time, or (ii) at any time,
                               in whole (but not in part), upon the occurrence

                               to 100% of the principal amount of the Junior

                               with any accrued but unpaid interest to the date

Distribution of Junior
  Subordinated Debentures....  The Company has the right at any time to dissolve
                               Sterling Capital and cause the Junior
                               Subordinated Debentures to be distributed to
                               holders of Capital Securities in liquidation of

                               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 Capital Securities --

                               Capital of Distributions and other amounts due on
                               the Capital Securities. Under the Guarantee, the

                               by Sterling Capital and payments on liquidation
                               of or redemption of the Capital Securities

                               to the extent of funds held by Sterling Capital.
                               If Sterling Capital has insufficient funds to pay
                               Distributions on the Capital Securities (i.e., if
                               the Company has failed to make required payments
                               under the Junior Subordinated Debentures), a
                               holder of the Capital Securities would have the
                               right to institute a legal proceeding directly
                               against the Company to enforce payment of such
                               Distributions to such holder. See "Description of

                               the Guarantee, the Junior Subordinated Debentures
                               and other documents described herein are

                               approximately $32.2 million. In addition, because
                               the Company is a savings and loan holding
                               company, all obligations of the Company relating

                               including Sterling Savings. The Company may cause
                               additional capital securities to be issued by
                               trusts similar to Sterling Capital in the future,
                               and there is no limit on the amount of such
                               securities that may be issued. In this event, the
                               Company's obligations under the junior
                               subordinated debentures to be issued to such
                               other trusts and the Company's guarantees of the
                               payments by such trusts will rank pari passu with
                               the Company's obligations under the Junior
                               Subordinated Debentures and the Guarantee,
                               respectively.
 
Voting Rights................  The holders of the Capital Securities will
                               generally have limited voting rights relating
                               only to the modification of the Capital
                               Securities, the dissolution, winding-up or
                               termination of Sterling Capital and certain other
                               matters described herein. See "Description of

</TABLE>
    
 
- ---------------
 
(1) During the six months ended December 31, 1996, the Company recorded a
    pre-tax charge to earnings of $5.8 million as a result of a non-recurring
    assessment to fund the Savings Association Insurance Fund ("SAIF").
 
(2) The extraordinary item is the loss associated with the early extinguishment
    of Federal Home Loan Bank advances, net of income taxes.
 
(3) The consolidated ratio of earnings to combined fixed charges and preferred
    stock dividends has been computed by dividing income before income taxes and
    fixed charges by fixed charges and preferred stock dividends. Fixed charges
    represent all interest expense (ratios are presented both excluding and
    including interest on deposits), amortization of notes and debenture expense
    and the portion of net rental expense which is deemed to be equivalent to
    interest on debt. Preferred stock dividends associated with outstanding
    preferred stock are increased to an amount representing the pre-tax earnings
    which would be required to cover such dividend requirements. Interest
    expense (other than on deposits) includes interest on notes and debentures,
    federal funds purchased and securities sold under agreements to repurchase,
    mortgages, commercial paper and other funds borrowed.
 
   
(4) Earnings were insufficient to cover combined fixed charges and preferred
    stock dividend requirements by $991,000. This was due to a net loss recorded
    during the period, which was primarily due to the non-recurring SAIF
    assessment of $5.8 million.

                                  RISK FACTORS
 
   
     In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating an investment in the
Capital Securities offered by this Prospectus. Certain statements in this
Prospectus and documents incorporated herein by reference are forward-looking
and are identified by the use of forward-looking words or phrases such as,
without limitation, "intended," "will be positioned," "expects," is or are
"expected," "anticipates," and "anticipated." These forward-looking statements
are based on the Company's current expectations. To the extent any of the
information contained or incorporated by reference in this Prospectus
constitutes a "forward-looking statement" as defined in Section 27A(i)(1) of the
Securities Act, the risk factors set forth below are cautionary statements
identifying important factors that could cause actual results to differ
materially from those in the forward-looking statement.
    
 
RANKING OF SUBORDINATED OBLIGATIONS UNDER THE GUARANTEE AND THE JUNIOR
SUBORDINATED DEBENTURES
 
   
     The obligations of the Company under the Guarantee issued by the Company
for the benefit of the holders of Capital Securities and under the Junior
Subordinated Debentures are subordinate and junior in right of payment to all
Senior Indebtedness. At March 31, 1997, the Senior Indebtedness of the Company
aggregated approximately $32.2 million. None of the Junior Subordinated
Indenture, the Guarantee or the Trust Agreement places any limitation on the
amount of secured or unsecured debt, including Senior Indebtedness, that may be
incurred by the Company. See "Description of Junior Subordinated Debentures --
Subordination" and "Description of Guarantee -- Status of the Guarantee."
Further, there is no limitation of the Company's ability to issue additional
junior subordinated debentures in connection with any future offerings of
capital securities, and any such additional debentures would rank pari passu
with the Junior Subordinated Debentures.
    
 
     The ability of Sterling Capital to pay amounts due on the Capital
Securities is solely dependent upon the Company's making payments on the Junior
Subordinated Debentures as and when required.
 
DIVIDEND PAYMENT SOURCES AND RESTRICTIONS
 
   
     The principal source of funds for payments by the Company (and
consequently, interest on the Junior Subordinated Debentures, Sterling Capital's
ability to pay Distributions on the Capital Securities and the Company's ability
to pay its obligations under the Guarantee) will be dividends from the Company's
principal subsidiary, Sterling Savings. Applicable rules and regulations of the
Office of Thrift Supervision (the "OTS") impose limitations on capital
distributions by savings institutions. Savings institutions, such as Sterling
Savings, which have capital in excess of all capital requirements before and
after the proposed capital distribution are permitted, after giving prior notice
to the OTS, to make capital distributions during a calendar year up to the
greater of (i) 100% of net income to date during the calendar year, plus the
amount that would reduce by one-half its "surplus capital" (its excess capital
over its regulatory capital requirements) at the beginning of the calendar year
or (ii) 75% of its net income over the most recent four quarter period. However,
such capital distribution may not reduce surplus capital below the regulatory
capital requirement at the date of the capital distribution. Institutions with
less capital are more restricted in payment of dividends and no institution can
pay dividends if such would cause the institution to no longer satisfy its
capital requirements.
    
 
STATUS OF THE COMPANY AS A SAVINGS AND LOAN HOLDING COMPANY
 
   
     The Company, as a savings and loan holding company, and Sterling Savings,
as a state-chartered savings and loan association with deposits insured by the
FDIC, are subject to significant supervision and regulation by the OTS, the FDIC
and the State of Washington Department of Financial Institutions (the
"Washington Supervisor"). This supervision and regulation is intended to protect
depositors, rather than holders of the Company's securities. The OTS and the
FDIC have adopted and proposed numerous regulations and undertaken other
regulatory initiatives in an effort to increase the safety and soundness of the
savings and loan industry. In addition, legislation has been enacted that
provides for regulatory seizure of insured institutions in the event of certain
declines in capital levels, requires risk-based deposit insurance premiums and
imposes
    
 
                                       13
<PAGE>   16
 
liability on holding companies for regulatory capital deficiencies of insured
institution subsidiaries under certain circumstances, among other significant
effects.
 
     The Company is a legal entity separate and distinct from Sterling Savings,
although the principal source of the Company's cash is dividends from Sterling
Savings. 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 Capital 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.
 
   
     Sterling Savings is also subject to restrictions under federal law which
limit the transfer of funds to the Company or to other affiliates, whether in
the form of loans, extensions of credit, investments, asset purchases or
otherwise. Such transfers by Sterling Savings to the Company or any other
affiliate are limited in amount to 10% of Sterling Savings' capital and surplus
and, with respect to the Company and all such other affiliates, to an aggregate
of 20% of Sterling Savings' capital and surplus. Furthermore, such loans and
extensions of credit are required to be collateralized.
    
 
CERTAIN REGULATORY MATTERS
 
     Sterling Savings is a State of Washington-chartered institution and is
subject to regulation by the Washington Supervisor, which conducts regular
examinations to ensure that Sterling Savings' operations and policies conform
with sound industry practice. Sterling Savings is currently subject to a
supervisory directive from the Washington Supervisor. The directive requires
Sterling Savings to provide monthly reports, maintain its current "well
capitalized" status, obtain prior approval for significant transactions and take
certain other corrective actions. The Company is in the process of completing
such corrective actions. Sterling Savings operates three branches within the
State of Oregon and is therefore also subject to the supervision of the Oregon
Department of Consumer and Business Services.
 
   
     The Company, as a savings and loan holding company, is not subject to
consolidated capital requirements. However, if certain legislation pending in
Congress is enacted, Sterling Savings may be required to convert its charter to
either a national bank charter, a state depository institution charter, or a
newly designed charter, in which case the Company may be required to register as
a bank holding company and become regulated at the holding company level by the
Federal Reserve rather than by the OTS. Regulation by the Federal Reserve could
subject the Company to capital requirements that are not currently applicable to
the Company as a savings and loan holding company under OTS regulation and may
result in statutory limitations on the type of business activities in which the
Company may engage at the holding company level, which business activities
currently are not restricted. At this time, the Company is unable to predict
whether a charter change will be required and, if it is, whether the charter
change will significantly impact Sterling Savings' operations.
    
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD; TAX CONSEQUENCES
 
     So long as no Event of Default (as defined in the Junior Subordinated
Indenture) has occurred and is continuing with respect to the Junior
Subordinated Debentures (a "Debenture Event of Default"), the Company has the
right under the Junior Subordinated Indenture to defer the payment of interest
on the Junior Subordinated Debentures at any time or from time to time for a
period not exceeding 20 consecutive quarterly periods with respect to each
Extension Period, provided that no Extension Period may extend beyond the Stated
Maturity of the Junior Subordinated Debentures. See "Description of Junior
Subordinated Debentures -- Debenture Events of Default." As a consequence of any
such deferral, quarterly Distributions on the Capital Securities by Sterling
Capital will be deferred during any such Extension Period. Distributions to
which holders of the Capital Securities are entitled will accumulate additional
Distributions thereon during any Extension Period at the rate of     % per
annum, compounded quarterly from the relevant payment date for such
Distributions, computed on the basis of a 360-day year of twelve 30-day months
and the actual days elapsed in a partial month in such period. Additional
Distributions payable for each full Distribution period will be computed by
dividing the rate per annum by four. The term "Distribution" as used herein
shall include
 
                                       14
<PAGE>   17
 
any such additional Distributions. 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 or (ii) make any payment of principal of or interest or
premium, if any, on or repay, repurchase or redeem any debt securities of the
Company that rank pari passu in all respects with or junior in interest to the
Junior Subordinated Debentures (other than (a) repurchases, redemptions or other
acquisitions of shares of capital stock of the Company in connection with any
employment contract, benefit plan or other similar arrangement with or for the
benefit of any one or more employees, officers, directors or consultants, in
connection with a dividend reinvestment or stockholder stock purchase plan or in
connection with the issuance of capital stock of the Company (or securities
convertible into or exercisable for such capital stock) as consideration in an
acquisition transaction entered into prior to the applicable Extension Period,
(b) as a result of an exchange or conversion of any class or series of the
Company's capital stock (or any capital stock of a subsidiary of the Company)
for any class or series of the Company's capital stock or of any class or series
of the Company's indebtedness for any class or series of the Company's capital
stock, (c) the purchase of fractional interests in shares of the Company's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged, (d) any declaration of a
dividend in connection with any stockholder's rights plan, or the issuance of
rights, stock or other property under any stockholder's rights plan, or the
redemption or repurchase of rights pursuant thereto, or (e) any dividend in the
form of stock, warrants, options or other rights where the dividend stock or the
stock issuable upon exercise of such warrants, options or other rights is the
same stock as that on which the dividend is being paid or ranks pari passu with
or junior to such stock). 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 quarterly periods or extend beyond
the Stated Maturity of the Junior 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 conditions. No interest shall
be due and payable during an Extension Period, except at the end thereof. The
Company must give the Sterling Capital Trustees notice of its election to begin
an Extension Period at least one Business Day prior to the earlier of (i) the
date the Distributions on the Capital Securities would have been payable but for
the election to begin such Extension Period and (ii) the date the Property
Trustee is required to give notice to holders of the Capital Securities of the
record date or the date such Distributions are payable, but in any event not
less than one Business Day prior to such record date. The Property Trustee will
give notice of the Company's election to begin a new Extension Period to the
holders of the Capital Securities. 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 Capital Securities -- Distributions" and
"Description of Junior Subordinated Debentures -- Option to Extend Interest
Payment Period."
 
   
     Should an Extension Period occur, a holder of Capital Securities will
continue to accrue income (in the form of original issue discount) in respect of
its pro rata share of the Junior Subordinated Debentures held by Sterling
Capital for United States federal income tax purposes. As a result, a holder of
Capital Securities will 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 Sterling Capital if the holder
disposes of the Capital Securities prior to the record date for the payment of
Distributions. See "Certain Federal Income Tax Consequences -- US
Holders -- Interest Income and Original Issue Discount" and "Certain Federal
Income Tax Consequences -- US Holders -- Sales of Capital Securities."
    
 
     The Company has no current intention of exercising its right to defer
payments of interest by extending the interest payment period on the Junior
Subordinated Debentures. However, should the Company elect to exercise such
right in the future, the market price of the Capital Securities is likely to be
affected. A holder that disposes of the Capital Securities during an Extension
Period, therefore, might not receive the same return on the investment as a
holder that continues to hold its Capital Securities. In addition, as a result
of the existence of the Company's right to defer interest payments, the market
price of the Capital Securities (which represent preferred undivided beneficial
interests in the assets of Sterling Capital) may be more volatile than the
market prices of other securities on which original issue discount or interest
accrues that are not subject to such deferrals.

TAX EVENT, INVESTMENT COMPANY EVENT OR CAPITAL TREATMENT EVENT REDEMPTION
 
   
     Upon the occurrence and during the continuation of a Tax Event, Investment
Company Event or Capital Treatment Event, the Company has the right to redeem
the Junior Subordinated Debentures in whole, but not in part, at any time within
90 days following the occurrence of such Tax Event, Investment Company Event or
Capital Treatment Event and thereby cause a mandatory redemption of the Capital
Securities. Any such redemption shall be at a price equal to the liquidation
amount of the Capital Securities, together with accumulated Distributions to but
excluding the date fixed for redemption. The ability of the Company to exercise
its rights to redeem the Junior Subordinated Debentures prior to the Stated
Maturity may be subject to prior regulatory approval by the Federal Reserve, if
then required under applicable Federal Reserve capital guidelines or policies.
See "Description of Capital Securities -- Liquidation Distribution Upon
Dissolution" and "Description of Junior Subordinated Debentures -- Redemption."
    
 
   
     A "Tax Event" means the receipt by Sterling Capital of an opinion of
counsel to the Company 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 or administrative pronouncement or action 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 Capital Securities, there is more than an insubstantial risk
that (i) Sterling Capital is, or will be within 90 days of the delivery of such
opinion, subject to United States federal income tax with respect to income
received or accrued on the Junior Subordinated Debentures, (ii) interest payable
by the Company on the Junior Subordinated Debentures is not, or within 90 days
of the delivery of such opinion will not be, deductible by the Company, in whole
or in part, for United States federal income tax purposes or (iii) Sterling
Capital is, or will be within 90 days of the delivery of the opinion, subject to
more than a de minimis amount of other taxes, duties or other governmental
charges.
    
 
   
     See "Certain Federal Income Tax Consequences -- US Holders -- Proposed 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 Capital Securities prior to             , 2002.
    
 
   
     "Investment Company Event" means the receipt by Sterling Capital of an
opinion of counsel to the Company experienced in such matters to the effect
that, as a result of the occurrence of a change in law or regulation or a
written change (including any announced prospective change) in interpretation or
application of law or regulation by any legislative body, court, governmental
agency or regulatory authority, there is more than an insubstantial risk that
Sterling Capital 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 or prospective change becomes
effective or would become effective, as the case may be, on or after the date of
the issuance of the Capital Securities.
    
 
   
     A "Capital Treatment Event" means the reasonable determination by the
Company that, as a result of the occurrence of any amendment to, or change
(including any announced prospective change) in, the laws (or any rules or
regulations thereunder) of the United States or any political subdivision
thereof or therein, or as a result of any official or administrative
pronouncement or action or judicial decision interpreting or applying such laws
or regulations, which amendment or change is effective or such pronouncement,
action or decision is announced on or after the date of issuance of the Capital
Securities, there is more than an insubstantial risk that the Company will not
be entitled to treat an amount equal to the Liquidation Amount of the Capital
Securities as Tier 1 Capital (or the then equivalent thereof) for purposes of
the risk-based capital adequacy guidelines of the Federal Reserve, as then in
effect, provided, however, that it shall not be deemed to be a Capital Treatment
Event if the Company is not entitled to treat the aggregate amount of the
Liquidation Amount of such Capital Securities as Tier 1 Capital due to the
restriction imposed by the Federal Reserve that no more than 25% of Tier 1
Capital can consist of perpetual preferred stock.

POSSIBLE TAX LAW CHANGES AFFECTING THE CAPITAL SECURITIES
 
   
     On February 6, 1997, President Clinton released his budget proposals for
fiscal year 1998. One of the tax proposals therein (the "Tax Proposal") would
generally deny corporate issuers a deduction for interest on certain debt
obligations that have a maximum term in excess of 15 years and are not shown as
indebtedness on the separate balance sheet of the issuer or, where the
instrument is issued to a related party (other than a corporation), where the
holder or some other related party issues a related instrument that is not shown
as indebtedness on the issuer's consolidated balance sheet. As currently
drafted, the Tax Proposal would be effective generally for instruments issued on
or after the date of first Congressional committee action. Although it is not
clear from the President's proposals as to what constitutes Congressional
"committee action" with respect to the Tax Proposal, it appears that, as
drafted, the Tax Proposal would not apply retroactively to the Junior
Subordinated Debentures. However, if the Tax Proposal (or similar legislation)
is enacted with retroactive effect with respect to the Junior Subordinated
Debentures, the Company may not be entitled to an interest deduction with
respect to the Junior Subordinated Debentures. There can be no assurances that
the Tax Proposal, if enacted, will not apply retroactively to the Junior
Subordinated Debentures or 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 Junior Subordinated Debentures. Accordingly, there can
be no assurance that a Tax Event will not occur. See "Description of Capital
Securities -- Redemption" and "Description of Junior Subordinated
Debentures -- Redemption." See also "Certain Federal Income Tax
Consequences -- US Holders -- Proposed Tax Law Changes."
    
 
DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES IN EXCHANGE FOR CAPITAL
SECURITIES
 
     The holders of all the outstanding Common Securities will have the right at
any time to dissolve Sterling Capital and, after satisfaction of liabilities to
creditors of Sterling Capital as provided by applicable law, cause the Junior
Subordinated Debentures to be distributed to the holders of the Capital
Securities and Common Securities in liquidation of Sterling Capital. The ability
of the Company to dissolve Sterling Capital may be subject to prior regulatory
approval of the Federal Reserve, if then required under applicable Federal
Reserve capital guidelines or policies. See "Description of Capital
Securities -- Liquidation Distribution Upon Dissolution."
 
   
     Under current United States federal income tax law and interpretations and
assuming, as expected, that Sterling Capital will not be taxable as a
corporation, a distribution of the Junior Subordinated Debentures upon a
liquidation of Sterling Capital will not be a taxable event to holders of the
Capital Securities. However, if a Tax Event were to occur that would cause
Sterling Capital to be subject to United States federal income tax with respect
to income received or accrued on the Junior Subordinated Debentures, a
distribution of the Junior Subordinated Debentures by Sterling Capital would be
a taxable event to Sterling Capital and the holders of the Capital Securities.
See "Certain Federal Income Tax Consequences -- US Holders -- Receipt of Junior
Subordinated Debentures or Cash upon Liquidation of Sterling Capital."
    
 
RIGHTS UNDER THE GUARANTEE
 
     Bankers Trust Company will act as the trustee under the Guarantee and will
hold the Guarantee for the benefit of the holders of the Capital Securities.
Bankers Trust Company will also act as Debenture Trustee for the Junior
Subordinated Debentures and as Property Trustee under the Trust Agreement.
Bankers Trust (Delaware) will act as Delaware Trustee under the Trust Agreement.
Under the Guarantee, the Company guarantees the holders of the Capital
Securities the following payments, to the extent not paid by or on behalf of
Sterling Capital: (i) any accumulated and unpaid Distributions required to be
paid on the Capital Securities, to the extent that Sterling Capital has funds on
hand available therefor at the payment date, (ii) the Redemption Price with
respect to any Capital Securities called for redemption, to the extent that
Sterling Capital has funds on hand available therefor at such time, and (iii)
upon a voluntary or involuntary dissolution, winding up or liquidation of
Sterling Capital (unless the Junior Subordinated Debentures are distributed to
holders of the Capital Securities), the lesser of (a) the aggregate of the
Liquidation Amount and all accumulated and unpaid Distributions to the date of
payment, to the extent that Sterling Capital has funds on hand available
therefor at such time, and (b) the amount of assets of Sterling Capital
remaining
 
                                       17
<PAGE>   20
 
available for distribution to holders of the Capital Securities on liquidation
of Sterling Capital. The Guarantee is subordinated as described under
"-- Ranking of Subordinated Obligations Under the Guarantee and the Junior
Subordinated Debentures" and "Description of Guarantee -- Status of the
Guarantee." The holders of not less than a majority in aggregate Liquidation
Amount of the outstanding Capital Securities have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Guarantee Trustee in respect of the Guarantee or to direct the exercise of any
trust power conferred upon the Guarantee Trustee under the Guarantee. Any holder
of the Capital Securities may institute a legal proceeding directly against the
Company to enforce its rights under the Guarantee without first instituting a
legal proceeding against Sterling Capital, the Guarantee Trustee or any other
person or entity.
 
   
     If the Company were to default on its obligation to pay amounts payable
under the Junior Subordinated Debentures, Sterling Capital would lack funds for
the payment of Distributions or amounts payable on redemption of the Capital
Securities or otherwise, and, in such event, holders of the Capital Securities
would not be able to rely upon the Guarantee for payment of such amounts.
Instead, if a Debenture Event of Default has occurred and is continuing and such
event is attributable to the failure of the Company to pay any amounts payable
in respect of the Junior Subordinated Debentures on the payment date on which
such payment is due and payable, then a holder of Capital Securities may
institute a legal proceeding directly against the Company for enforcement of
payment to such holder of any amounts payable in respect of such Junior
Subordinated Debentures having a principal amount equal to the aggregate
Liquidation Amount of the Capital Securities of such holder (a "Direct Action").
In connection with such Direct Action, the Company will have a right of set-off
under the Junior Subordinated Indenture to the extent of any payment made by the
Company to such holder of Capital Securities in the Direct Action. Except as
described herein, holders of Capital Securities will not be able to exercise
directly any other remedy available to the holders of the Junior Subordinated
Debentures or assert directly any other rights in respect of the Junior
Subordinated Debentures. See "Description of Junior Subordinated
Debentures -- Debenture Events of Default," "Description of Junior Subordinated
Debentures -- Enforcement of Certain Rights by Holders of Capital Securities"
and "Description of Guarantee." The Trust Agreement provides that each holder of
Capital Securities by acceptance thereof agrees to the provisions of the
Guarantee and the Junior Subordinated Indenture.
    
 
LIMITED VOTING RIGHTS
 
   
     Holders of Capital Securities will have limited voting rights relating
generally to the modification of the Capital Securities and the Guarantee and
the exercise of Sterling Capital's rights as holder of Junior Subordinated
Debentures. Holders of Capital Securities will not be entitled to appoint,
remove or replace the Property Trustee or the Delaware Trustee except upon the
occurrence of certain events specified in the Trust Agreement. The Property
Trustee and the holders of all the Common Securities may, subject to certain
conditions, amend the Trust Agreement without the consent of holders of Capital
Securities to cure any ambiguity or make other provisions not inconsistent with
the Trust Agreement or to ensure that Sterling Capital (i) will not be taxable
as a corporation for United States federal income tax purposes, or (ii) will not
be required to register as an "investment company" under the Investment Company
Act. See "Description of Capital Securities -- Removal of Sterling Capital
Trustees; Appointment of Successors" and "Description of Capital
Securities -- Voting Rights; Amendment of Trust Agreement."
    
 
ABSENCE OF EXISTING PUBLIC MARKET; MARKET PRICES
 
   
     There is no existing market for the Capital Securities. An application has
been made to include the Capital Securities for listing on the Nasdaq National
Market. There can be no assurance that an active and liquid trading market for
the Capital Securities will develop or that a listing of the Capital Securities
will be available on the Nasdaq National Market. Although each Underwriter has
informed Sterling Capital and the Company that such Underwriter intends to make
a market in the Capital Securities offered hereby, the Underwriters are not
obligated to do so and any such market making activity may be terminated at any
time without notice to the holders of the Capital Securities. Future trading
prices of the Capital Securities will depend on many factors including, among
other things, prevailing interest rates, the operating results and financial
condition of the Company, and the market for similar securities. There can be no
assurance as to the
    
 
                                       18
<PAGE>   21
 
   
market prices for the Capital Securities or the Junior Subordinated Debentures
that may be distributed in exchange for the Capital Securities if the holders of
all the Common Securities exercise their right to dissolve Sterling Capital.
Accordingly, the Capital Securities that an investor may purchase, or the Junior
Subordinated Debentures that a holder of the Capital Securities may receive in
liquidation of Sterling Capital, may decline in value from the price that the
investor paid to purchase the Capital Securities offered hereby.
    
 
FOCUS ON COMMUNITY BANKING
 
   
     In recent years, the Company has focused its efforts on becoming more like
a community retail bank. The Company is increasing its business banking,
consumer and construction lending while placing an increased emphasis on
attracting greater volumes of retail deposits. Business banking, consumer and
construction loans generally produce higher yields than residential mortgage
loans. Such loans, however, generally involve a higher degree of risk than the
financing of residential real estate, primarily because the collateral may be
difficult to obtain or liquidate in the event of default. Construction lending
is subject to risks such as construction delays, cost overruns, insufficient
collateral and the inability to obtain permanent financing in a timely manner.
Business banking and construction loans are more expensive to originate than
residential mortgage loans. As a result, the Company's operating expenses are
likely to increase as the Company increases its lending in these areas.
Additionally, the Company is likely to experience higher levels of loan losses
than it would on residential mortgage loans. There can be no assurance that the
Company's emphasis on community banking will be successful or that any increase
in the yields on business banking, consumer and construction loans will offset
higher levels of expense and losses on such loans.
    
 
   
LOAN PORTFOLIO CONCENTRATION IN CONSTRUCTION LOANS
    
 
   
     At March 31, 1997, approximately 16% of Sterling Savings' total loan
portfolio consisted of one- to four-family residential construction loans,
approximately 72% of which were for properties that were not custom built or
pre-sold. Further, approximately 80% of Sterling Savings' one- to four-family
residential construction loan portfolio was concentrated in the Portland, Oregon
market which is served by one loan production office. A reduction in the demand
for residential housing could have a negative impact on Sterling Savings and
therefore on the Company. In addition, at March 31, 1997, another 9% of Sterling
Savings' loan portfolio consisted of multifamily residential construction and
commercial property construction loans.
    
 
ALLOWANCE FOR LOAN LOSSES
 
   
     Inability of borrowers to repay loans can erode earnings and capital of
financial institutions. Like all financial institutions, Sterling Savings
maintains an allowance for loan losses to provide for loan defaults and
nonperformance. The allowance is based on prior experience with loan losses, as
well as an evaluation of the risks in the current portfolio, and is maintained
at a level considered adequate by management to absorb anticipated losses. The
amount of future losses is susceptible to changes in economic, operating and
other conditions, including changes in interest rates, that may be beyond
management's control, and such losses may exceed current estimates. At March 31,
1997, Sterling Savings had nonperforming loans of $2.7 million and an allowance
for loan losses of $8.0 million or 0.74% of total loans and 297% of
nonperforming loans. There can be no assurance that Sterling Savings' allowance
for loan losses will be adequate to cover actual losses. Future provisions for
loan losses could materially and adversely affect results of operations of the
Company.
    
 
ECONOMIC CONDITIONS AND IMPACT OF INTEREST RATES
 
   
     Results of operations for financial institutions, including the Company,
may be materially and adversely affected by changes in prevailing economic
conditions, including declines in real estate values, rapid changes in interest
rates and the monetary and fiscal policies of the federal government. The
profitability of the Company is in part a function of the spread between the
interest rates earned on assets and the interest rates paid on deposits and
other interest-bearing liabilities, including advances from the Federal Home
Loan Bank of Seattle ("FHLB"). A decrease in interest rate spreads would have a
negative effect on the net interest income and profitability of the Company, and
there can be no assurance that this spread will not decrease. Although economic
conditions in the market area of the Company have been generally stronger than
those in many other regions of the country, there can be no assurance that such
conditions will continue to prevail.
    
 
                                       19
<PAGE>   22
 
   
Moreover, substantially all of the loans of the Company are to individuals and
businesses in the Pacific Northwest, and any decline in the economy of this
market area could have an adverse impact on the Company.
    
 
   
     Currently, the Company's interest-bearing liabilities, consisting primarily
of savings deposits, FHLB advances and other borrowings, mature or reprice more
rapidly, or on different terms, than do its interest-earning assets. The fact
that liabilities mature or reprice more frequently on average than assets may be
beneficial in times of declining interest rates; however, such an
asset/liability structure may result in declining net interest income during
periods of rising interest rates. Additionally, the extent to which borrowers
prepay loans is affected by prevailing interest rates. When interest rates
increase, borrowers are less likely to prepay loans; whereas when interest rates
decrease, borrowers are more likely to prepay loans. Prepayments may affect the
levels of loans retained in an institution's portfolio, as well as its net
interest income.
    
 
GROWTH AND ACQUISITION STRATEGIES
 
   
     The Company has pursued and intends to continue to pursue an internal
growth strategy, the success of which will depend primarily on generating an
increasing level of loans and deposits at acceptable risk levels and terms
without proportionate increases in non-interest expenses. There can be no
assurance that the Company will be successful in implementing its internal
growth strategy. In addition, the Company has grown and may seek to grow by
acquiring other financial institutions. Any acquisitions will be subject to
regulatory approval, and there can be no assurance that the Company will be able
to obtain such approvals. The Company may not be successful in identifying
further acquisition candidates, integrating acquired institutions or preventing
deposit erosion or loan quality deterioration at acquired institutions.
Competition for acquisitions in the Company's market area is highly competitive,
and the Company may not be able to acquire other institutions on attractive
terms. Furthermore, the success of the growth strategy of the Company will
depend on maintaining sufficient regulatory capital levels and on continued
favorable economic conditions in the Pacific Northwest.
    
 
NEED FOR TECHNOLOGICAL CHANGE
 
   
     The banking industry is undergoing rapid technological changes with
frequent introductions of new technology-driven products and services. In
addition to better serving customers, the effective use of technology increases
efficiency and enables financial institutions to reduce costs. The Company's
future success will depend in part on its ability to address the needs of its
customers by using technology to provide products and services that will satisfy
customer demands for convenience as well as to create additional efficiencies in
Sterling Savings' operations. Many of Sterling Savings' competitors have
substantially greater resources to invest in technological improvements. There
can be no assurance that the Company will be able to effectively implement new
technology-driven products and services or be successful in marketing such
products and services to its customers.
    
 
COMPETITIVE BANKING ENVIRONMENT
 
     The banking business in the Pacific Northwest is highly competitive. The
Company competes for loans and deposits with local, regional and national
commercial banks, savings banks, savings and loan associations, finance
companies, money market funds, brokerage houses, credit unions and nonfinancial
institutions, many of which have substantially greater financial resources than
the Company. Interstate banking is permitted in Washington. After a phase-in
period ending July 1, 1997, full state-wide branch banking will be permitted. As
a result, management believes that the Company may experience greater
competition in its market area.

                                USE OF PROCEEDS
 
   
     All the proceeds to Sterling Capital from the sale of the Capital
Securities will be invested by Sterling Capital in the Junior Subordinated
Debentures. The net proceeds to the Company from the sale of Junior Subordinated
Debentures are estimated to be $     million. The Company initially intends to
contribute approximately $25.0 million of the net proceeds of the offering to
Sterling Savings to enhance Sterling Savings' regulatory capital ratios. The
remaining net proceeds to be received by the Company from the sale of the Junior
Subordinated Debentures will be used for general corporate purposes, which may
include the repayment of indebtedness of the Company, investments in or
extensions of credit to subsidiaries, the possible redemption of the Company's
outstanding $1.8125 Series A Cumulative Convertible Preferred Stock and the
financing of possible acquisitions. The decision to call such Cumulative
Convertible Preferred Stock for redemption will depend on several factors
including the market price of the Company's Common Stock and the likelihood that
holders of the Cumulative Convertible Preferred Stock will exercise their option
to convert their interest into shares of the Company's Common Stock rather than
accept cash redemption. Pending such uses, the net proceeds may be temporarily
invested in short- and intermediate-term investment-grade obligations or
deposited in interest-bearing accounts with Sterling Savings or other
institutions. 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.
    
 
   
     Although the Company, as a savings and loan holding company, is not subject
to the Federal Reserve capital requirements for bank holding companies, it is
possible that in the future it could become subject to such requirements as a
result of the acquisition of a bank, a change in applicable regulations or the
Company otherwise becoming subject to Federal Reserve capital requirements. On
October 21, 1996, the Federal Reserve announced that certain qualifying amounts
of cumulative preferred securities having the characteristics of the Capital
Securities could be included as Tier 1 capital for bank holding companies. Such
Tier 1 capital treatment, together with the Company's ability to deduct, for
income tax purposes, interest payable on the Junior Subordinated Debentures
provides the Company with a more cost-effective means of obtaining capital for
regulatory purposes than if the Company were to issue preferred stock.
    
 
                              ACCOUNTING TREATMENT
 
   
     For financial reporting purposes, Sterling Capital will be treated as a
subsidiary of the Company and, accordingly, the accounts of Sterling Capital
will be included in the consolidated financial statements of the Company. The
Capital Securities will be included in the consolidated balance sheets of the
Company under the caption "Company obligated mandatorily redeemable preferred
securities of subsidiary trust holding solely Junior Subordinated Debentures"
and appropriate disclosures about the Capital Securities, the Guarantee and the
Junior Subordinated Debentures will be included in the Notes to the Consolidated
Financial Statements of the Company. For financial reporting purposes,
Distributions on the Capital Securities will be recorded as interest expense in
the consolidated statements of income of the Company.

(1) The subsidiary trust is Sterling Capital, a wholly owned subsidiary of the
    Company that will hold approximately $41.2 million principal amount of
    Junior Subordinated Debentures issued by the Company to Sterling Capital as
    its sole asset. The Capital Securities are issued by Sterling Capital. See
    "Description of Junior Subordinated Debentures." The Company owns all of the
    Common Securities of Sterling Capital.
 
   
(2) Although the Company, as a savings and loan holding company, is not subject
    to the Federal Reserve capital requirements for bank holding companies, the
    Capital Securities have been structured to qualify as Tier 1 capital,
    subject to certain limitations if the Company were to become regulated as a
    bank holding company. At March 31, 1997, approximately $29.0 million of the
    Capital Securities would have qualified as Tier 1 Capital, if the Company's
    outstanding Cumulative Convertible Preferred Stock had been converted into
    Common Stock of the Company at that date. There can be no assurance that the
    Company's Cumulative Convertible Preferred Stock will be converted into
    Common Stock and, if it is not so converted, the amount of the Capital
    Securities that would qualify as Tier 1 Capital would be significantly less
    than $29 million. The "as adjusted" ratios are based upon initial
    contribution by the Company of approximately $25.0 million of the net
    proceeds of this offering to Sterling Savings and assume the investment of
    such amount of net proceeds in assets with 100% risk weighting under the
    risk-based capital rules of the OTS. See "Use of Proceeds."

                       DESCRIPTION OF CAPITAL SECURITIES
 
     Pursuant to the terms of the Trust Agreement for Sterling Capital, the
Sterling Capital Trustees on behalf of Sterling Capital will issue the Capital
Securities and the Common Securities. The Capital Securities will represent
preferred undivided beneficial interests in the assets of Sterling Capital 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. This summary of certain provisions of the Capital Securities and the
Trust Agreement does not purport to be complete and is subject to, and qualified
in its entirety by reference to, all the provisions of the Trust Agreement,
including the definitions therein of certain terms. Wherever particular defined
terms of the Trust Agreement are referred to herein, such defined terms are
incorporated herein by reference. A copy of the form of the Trust Agreement is
available upon request from the Sterling Capital Trustees.
 
GENERAL
 
     The Capital Securities will be limited to $40,000,000 aggregate Liquidation
Amount outstanding. The Capital Securities will rank pari passu, and payments
will be made thereon pro rata, with the Common Securities except as described
under "-- Subordination of Common Securities." The Junior Subordinated
Debentures will be registered in the name of Sterling Capital and held by the
Property Trustee in trust for the benefit of the holders of the Capital
Securities and Common Securities. The Guarantee will be a guarantee on a
subordinated basis with respect to the Capital Securities but will not guarantee
payment of Distributions or amounts payable on redemption or liquidation of such
Capital Securities when Sterling Capital does not have funds on hand available
to make such payments. See "Description of Guarantee."
 
DISTRIBUTIONS
 
     Payment of Distributions. The Capital Securities represent preferred
undivided beneficial interests in the assets of Sterling Capital, and
Distributions on each Capital Security will be payable at the annual rate
of     % of the stated Liquidation Amount of $25, payable quarterly in arrears
on September 30, December 31, March 31 and June 30 of each year (each a
"Distribution Date"), to the holders of the Capital Securities at the close of
business on September 15, December 15, March 15 and June 15 (whether or not a
Business Day (as defined below)) next preceding the relevant Distribution Date.
The amount of each Distribution due with respect to the Capital Securities will
include amounts accrued through the date the Distribution is due. Distributions
on the Capital Securities will be cumulative. Distributions will accumulate from
the date of original issuance. The first Distribution Date for the Capital
Securities will be September 30, 1997. The amount of Distributions payable for
any period less than a full Distribution period will be computed on the basis of
a 360-day year of twelve 30-day months and the actual days elapsed in a partial
month in such
 
                                       25
<PAGE>   28
 
period. Distributions payable for each full Distribution period will be computed
by dividing the rate per annum by four. If any date on which Distributions are
payable on the Capital 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 (without any additional Distributions 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.
 
     The funds of Sterling Capital available for distribution to holders of the
Capital Securities will be limited to payments under the Junior Subordinated
Debentures in which Sterling Capital will invest the proceeds from the issuance
and sale of the Capital Securities. See "Description of Junior Subordinated
Debentures." If the Company does not make payments on the Junior Subordinated
Debentures, Sterling Capital may not have funds available to pay Distributions
or other amounts payable on the Capital Securities. The payment of Distributions
and other amounts payable on the Capital Securities (if and to the extent
Sterling Capital has funds legally available for and cash sufficient to make
such payments) is guaranteed by the Company on a limited basis as set forth
herein under "Description of Guarantee."
 
     Extension Period. So long as no Debenture Event of Default has occurred and
is continuing, the Company has the right under the Junior Subordinated Indenture
to defer the payment of interest on the Junior Subordinated Debentures at any
time or from time to time for a period not exceeding 20 consecutive quarterly
periods with respect to each Extension Period, provided that no Extension Period
may extend beyond the Stated Maturity of the Junior Subordinated Debentures. As
a consequence of any such deferral, quarterly Distributions on the Capital
Securities by Sterling Capital will be deferred during any such Extension
Period. Distributions to which holders of the Capital Securities are entitled
will accumulate additional Distributions thereon at the rate of     % per annum,
compounded quarterly from the relevant payment date for such Distributions,
computed on the basis of a 360-day year of twelve 30-day months and the actual
days elapsed in a partial month in such period. Additional Distributions payable
for each full Distribution period will be computed by dividing the rate per
annum by four. The term "Distributions" as used herein shall include any such
additional Distributions. 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 or (ii) make any payment of principal of or interest or premium,
if any, on or repay, repurchase or redeem any debt securities of the Company
that rank pari passu in all respects with or junior in interest to the Junior
Subordinated Debentures (other than (a) repurchases, redemptions or other
acquisitions of shares of capital stock of the Company in connection with any
employment contract, benefit plan or other similar arrangement with or for the
benefit of any one or more employees, officers, directors or consultants, in
connection with a dividend reinvestment or stockholder stock purchase plan or in
connection with the issuance of capital stock of the Company (or securities
convertible into or exercisable for such capital stock) as consideration in an
acquisition transaction entered into prior to the applicable Extension Period,
(b) as a result of an exchange or conversion of any class or series of the
Company's capital stock (or any capital stock of a subsidiary of the Company)
for any class or series of the Company's capital stock or of any class or series
of the Company's indebtedness for any class or series of the Company's capital
stock, (c) the purchase of fractional interests in shares of the Company's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged, (d) any declaration of a
dividend in connection with any stockholder's rights plan, or the issuance of
rights, stock or other property under any stockholder's rights plan, or the
redemption or repurchase of rights pursuant thereto, or (e) any dividend in the
form of stock, warrants, options or other rights where the dividend stock or the
stock issuable upon exercise of such warrants, options or other rights is the
same stock as that on which the dividend is being paid or ranks pari passu with
or junior to such stock). 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 quarterly periods or extend beyond
the Stated Maturity of the Junior 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. No interest shall be due and
payable during an Extension Period, except at the end thereof. The Company must
give the Sterling Capital Trustees notice of its election of such Extension
Period at least one Business Day prior to the earlier of (i) the date the
Distributions on the Capital Securities would have been payable but for the
election to begin such Extension Period and (ii) the date the Property Trustee
is required to give notice to holders of the Capital Securities of the record
date or the date
 
                                       26
<PAGE>   29
 
such Distributions are payable, but in any event not less than one Business Day
prior to such record date. The Property Trustee will give notice of the
Company's election to begin a new Extension Period to the holders of the Capital
Securities. 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 Junior Subordinated Debentures -- Option To Extend Interest Payment Period"
and "Certain Federal Income Tax Consequences -- US Holders -- Interest Income
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 Junior
Subordinated Debentures.
 
REDEMPTION
 
     Mandatory Redemption of Capital Securities. Upon the repayment or
redemption, in whole or in part, of the Junior Subordinated Debentures, whether
at maturity or upon earlier redemption as provided in the Junior Subordinated
Indenture, the proceeds from such repayment or redemption shall be applied by
the Property Trustee to redeem a Like Amount (as defined below) of the Capital
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
Capital Securities plus accumulated but unpaid Distributions thereon to but
excluding the date of redemption (the "Redemption Date"). See "Description of
Junior Subordinated Debentures -- Redemption." If less than all the Junior
Subordinated Debentures are to be repaid or redeemed on a Redemption Date, then
the proceeds from such repayment or redemption shall be allocated to the
redemption pro rata of the Capital Securities and the Common Securities.
 
     Optional Redemption of Junior Subordinated Debentures. The Company has the
right to redeem the Junior Subordinated Debentures (i) on or after             ,
2002, in whole at any time or in part from time to time, or (ii) in whole, but
not in part, at any time within 90 days following the occurrence and during the
continuation of a Tax Event, Investment Company Event or Capital Treatment Event
(each as defined below), in each case subject to possible regulatory approval.
See "-- Liquidation Distribution Upon Dissolution." A redemption of the Junior
Subordinated Debentures would cause a mandatory redemption of a Like Amount of
the Capital Securities and Common Securities at the Redemption Price.
 
     Payment of Additional Sums. If a Tax Event described in clause (i) or (iii)
of the definition of Tax Event above has occurred and is continuing and Sterling
Capital is the holder of all the Junior Subordinated Debentures, the Company
will pay Additional Sums (as defined below), if any, on the Junior Subordinated
Debentures.
 
DEFINITIONS
 
     "Additional Sums" means the additional amounts as may be necessary in order
that the amount of Distributions then due and payable by Sterling Capital on the
outstanding Capital Securities and Common Securities of Sterling Capital will
not be reduced as a result of any additional taxes, duties and other
governmental charges to which Sterling Capital has become subject as a result of
a Tax Event.
 
     "Business Day" means a day other than (a) a Saturday or Sunday, (b) a day
on which banking institutions in the City of New York or the City of Spokane are
authorized or required by law or executive order to remain closed, or (c) a day
on which the Property Trustee's Corporate Trust Office or the Corporate Trust
Office of the Debenture Trustee is closed for business.
 
     "Capital Treatment Event" means the reasonable determination by the Company
that, as a result of the occurrence of any amendment to, or change (including
any announced prospective change) in, the laws (or any rules or regulations
thereunder) of the United States or any political subdivision thereof or
therein, or as a result of any official or administrative pronouncement or
action or judicial decision interpreting or applying such laws or regulations,
which amendment or change is effective or such pronouncement, action or decision
is announced on or after the date of issuance of the Capital Securities, there
is more than an insubstantial risk that the Company will not be entitled to
treat an amount equal to the Liquidation Amount of the Capital Securities as
Tier 1 Capital (or the then equivalent thereof) for purposes of the risk-based
capital adequacy
 
                                       27
<PAGE>   30
 
   
guidelines of the Board of Governors of the Federal Reserve System, as then in
effect, provided, however, that it shall not be deemed to be a Capital Treatment
Event if the Company is not entitled to treat the aggregate amount of the
Liquidation Amount of such Capital Securities as Tier 1 Capital due to the
restriction imposed by the Federal Reserve that no more than 25% of Tier 1
Capital can consist of perpetual preferred stock.
    
 
     "Investment Company Event" means the receipt by Sterling Capital of an
opinion of counsel to the Company experienced in such matters to the effect
that, as a result of the occurrence of a change in law or regulation or a
written change (including any announced prospective change) in interpretation or
application of law or regulation by any legislative body, court, governmental
agency or regulatory authority, there is more than an insubstantial risk that
Sterling Capital is or will be considered an "investment company" that is
required to be registered under the Investment Company Act, which change or
prospective change becomes effective or would become effective, as the case may
be, on or after the date of the issuance of the Capital Securities.
 
     "Like Amount" means (i) with respect to a redemption of Trust Securities,
Trust Securities having a Liquidation Amount (as defined below) equal to that
portion of the principal amount of Junior Subordinated Debentures to be
contemporaneously redeemed in accordance with the Junior Subordinated Indenture,
allocated to the Common Securities and to the Capital Securities based upon the
relative Liquidation Amounts of such classes and (ii) with respect to a
distribution of Junior Subordinated Debentures to holders of Trust Securities in
connection with a dissolution or liquidation of Sterling Capital, Junior
Subordinated Debentures having a principal amount equal to the Liquidation
Amount of the Trust Securities of the holder to whom such Junior Subordinated
Debentures are distributed.
 
     "Liquidation Amount" means the stated amount of $25 per Trust Security.
 
   
     "Tax Event" means the receipt by Sterling Capital of an opinion of counsel
to the Company 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 or administrative pronouncement or action 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 Capital Securities, there is more than an insubstantial risk
that (i) Sterling Capital is, or will be within 90 days of the delivery of such
opinion, subject to United States federal income tax with respect to income
received or accrued on the Junior Subordinated Debentures, (ii) interest payable
by the Company on the Junior Subordinated Debentures is not, or within 90 days
of the delivery of such opinion, will not be, deductible by the Company, in
whole or in part, for United States federal income tax purposes or (iii)
Sterling Capital is, or will be within 90 days of the delivery of such opinion,
subject to more than a de minimis amount of other taxes, duties or other
governmental charges.
    
 
REDEMPTION PROCEDURES
 
     Capital Securities redeemed on each Redemption Date shall be redeemed at
the Redemption Price with the applicable proceeds from the contemporaneous
redemption of the Junior Subordinated Debentures. Redemptions of the Capital
Securities shall be made and the Redemption Price shall be payable on each
Redemption Date only to the extent that Sterling Capital has funds on hand
available for the payment of such Redemption Price. See also "-- Subordination
of Common Securities."
 
     If Sterling Capital gives a notice of redemption in respect of the Capital
Securities, then, by 12:00 noon, New York City time, on the Redemption Date, to
the extent funds are available, in the case of Capital Securities held in
book-entry form, the Property Trustee will deposit irrevocably with DTC funds
sufficient to pay the applicable Redemption Price and will give DTC irrevocable
instructions and authority to pay the Redemption Price to the holders of the
Capital Securities. With respect to Capital Securities not held in book-entry
form, the Property Trustee, to the extent funds are available, will irrevocably
deposit with the paying agent for the Capital Securities funds sufficient to pay
the applicable Redemption Price and will give such paying agent irrevocable
instructions and authority to pay the Redemption Price to the holders thereof
upon
 
                                       28
<PAGE>   31
 
surrender of their certificates evidencing the Capital Securities.
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date for any Capital Securities called for redemption shall be
payable to the holders of the Capital 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 the holders of such Capital Securities so called for redemption will
cease, except the right of the holders of such Capital Securities to receive the
Redemption Price, but without interest on such Redemption Price, and such
Capital Securities will cease to be outstanding. If any date fixed for
redemption of Capital 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 (without any interest or other payment in respect of any
such delay), except that, if such Business Day falls in the next calendar year,
such payment will be made on the immediately preceding Business Day. In the
event that payment of the Redemption Price in respect of Capital Securities
called for redemption is improperly withheld or refused and not paid either by
Sterling Capital or by the Company pursuant to the Guarantee as described under
"Description of Guarantee," Distributions on such Capital Securities will
continue to accumulate at the then applicable rate, from the Redemption Date
originally established by Sterling Capital for such Capital Securities to the
date such Redemption Price is actually paid, in which case the actual payment
date will be the date fixed for redemption for purposes of calculating the
Redemption Price.
 
     Subject to applicable law (including, without limitation, United States
federal securities laws), the Company or its affiliates may at any time and from
time to time purchase outstanding Capital Securities by tender, in the open
market or by private agreement, and may resell such securities.
 
     If less than all the Capital Securities and Common Securities are to be
redeemed on a Redemption Date, then the aggregate Liquidation Amount of such
Capital Securities and Common Securities to be redeemed shall be allocated pro
rata to the Capital Securities and the Common Securities based upon the relative
Liquidation Amounts of such classes. The particular Capital Securities to be
redeemed shall be selected on a pro rata basis not more than 60 days prior to
the Redemption Date by the Property Trustee from the outstanding Capital
Securities not previously called for redemption, or if the Capital Securities
are then held in the form of a Global Preferred Security (as defined below), in
accordance with DTC's customary procedures. The Property Trustee shall promptly
notify the securities registrar for the Trust Securities in writing of the
Capital Securities selected for redemption and, in the case of any Capital
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 Capital Securities shall
relate, in the case of any Capital Securities redeemed or to be redeemed only in
part, to the portion of the aggregate Liquidation Amount of Capital 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 registered holder of Capital
Securities to be redeemed at its address appearing on the securities register
for the Trust Securities. Unless the Company defaults in payment of the
Redemption Price on the Junior Subordinated Debentures, on and after the
Redemption Date interest will cease to accrue on the Junior Subordinated
Debentures or portions thereof (and, unless payment of the Redemption Price in
respect of the Capital Securities is withheld or refused and not paid either by
Sterling Capital or the Company pursuant to the Guarantee, Distributions will
cease to accumulate on the Capital Securities or portions thereof) called for
redemption.
 
SUBORDINATION OF COMMON SECURITIES
 
     Payment of Distributions on, and the Redemption Price of, and the
Liquidation Distribution in respect of, the Capital Securities and Common
Securities, as applicable, shall be made pro rata based on the Liquidation
Amount of such Capital Securities and Common Securities. However, if on any
Distribution Date or Redemption Date a Debenture Event of Default has occurred
and is continuing as a result of any failure by the Company to pay any amounts
in respect of the Junior Subordinated Debentures when due, no payment of any
Distribution on, or Redemption Price of, or Liquidation Distribution in respect
of, any of the Common Securities, and no other payment on account of the
redemption, liquidation or other acquisition of such Common Securities, shall be
made unless payment in full in cash of all accumulated and unpaid Distributions
 
                                       29
<PAGE>   32
 
on all the outstanding Capital 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 the outstanding Capital
Securities then called for redemption, shall have been made or provided for, and
all funds available to the Property Trustee shall first be applied to the
payment in full in cash of all Distributions on, or Redemption Price of, the
Capital Securities then due and payable.
 
     In the case of any Event of Default (as defined below) resulting from a
Debenture Event of Default, the holders 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 effects of all such Events of Default with respect
to such Capital Securities have been cured, waived or otherwise eliminated. See
"-- Events of Default; Notice" and "Description of Junior Subordinated
Debentures -- Debenture Events of Default." Until all such Events of Default
under the Trust Agreement with respect to the Capital Securities have been so
cured, waived or otherwise eliminated, the Property Trustee will act solely on
behalf of the holders of the Capital Securities and not on behalf of the holders
of the Common Securities, and only the holders of the Capital Securities will
have the right to direct the Property Trustee to act on their behalf.
 
LIQUIDATION DISTRIBUTION UPON DISSOLUTION
 
     The amount payable on the Capital Securities in the event of any
liquidation of Sterling Capital is $25 per Capital Security plus accumulated and
unpaid Distributions, subject to certain exceptions, which may be in the form of
a distribution of such amount in Junior Subordinated Debentures.
 
     The holders of all the outstanding Common Securities will have the right at
any time to dissolve Sterling Capital and, after satisfaction of liabilities to
creditors of Sterling Capital as provided by applicable law, cause the Junior
Subordinated Debentures to be distributed to the holders of the Capital
Securities and Common Securities in liquidation of Sterling Capital.
 
     The Federal Reserve's risk-based capital guidelines currently provide that
redemptions of permanent equity or other capital instruments before stated
maturity could have a significant impact on a bank holding company's overall
capital structure and that any organization considering such a redemption should
consult with the Federal Reserve before redeeming any equity or capital
instrument prior to maturity if such redemption could have a material effect on
the level or composition of the organization's capital base (unless the equity
or capital instrument were redeemed with the proceeds of, or replaced by, a like
amount of a similar or higher quality capital instrument and the Federal Reserve
considers the organization's capital position to be fully adequate after the
redemption).
 
     In the event the Company, while a holder of Common Securities, dissolves
Sterling Capital prior to the Stated Maturity of the Capital Securities and the
dissolution of Sterling Capital is deemed to constitute the redemption of
capital instruments by the Federal Reserve under its risk-based capital
guidelines or policies, the dissolution of Sterling Capital by the Company may
be subject to the prior approval of the Federal Reserve. Moreover, any changes
in applicable law or changes in the Federal Reserve's risk-based capital
guidelines or policies could impose a requirement on the Company that it obtain
the prior approval of the Federal Reserve to dissolve Sterling Capital.
 
     Pursuant to the Trust Agreement, Sterling Capital will automatically
dissolve upon expiration of its term or, if earlier, will dissolve on the first
to occur of: (i) certain events of bankruptcy, dissolution or liquidation of the
Company or the holder of the Common Securities, (ii) the distribution of a Like
Amount of the Junior Subordinated Debentures to the holders of the Trust
Securities, if the holders of Common Securities have given written direction to
the Property Trustee to dissolve Sterling Capital (which direction, subject to
the foregoing restrictions, is optional and wholly within the discretion of the
holders of Common Securities), (iii) the repayment of all the Capital Securities
in connection with the redemption of all the Trust Securities as described under
"-- Redemption" and (iv) the entry of an order for the dissolution of Sterling
Capital by a court of competent jurisdiction.
 
     If dissolution of Sterling Capital occurs as described in clause (i), (ii)
or (iv) above, Sterling Capital will be liquidated by the Property Trustee as
expeditiously as the Property Trustee determines to be possible by
 
                                       30
<PAGE>   33
 
distributing, after satisfaction of liabilities to creditors of Sterling Capital
as provided by applicable law, to the holders of such Trust Securities a Like
Amount of the Junior Subordinated Debentures, unless such distribution is not
practical, in which event such holders will be entitled to receive out of the
assets of Sterling Capital available for distribution to holders, after
satisfaction of liabilities to creditors of Sterling Capital as provided by
applicable law, an amount equal to, in the case of holders of Capital
Securities, the aggregate of the Liquidation Amount plus accumulated 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 Sterling Capital has insufficient assets available to pay in full the
aggregate Liquidation Distribution, then the amounts payable directly by
Sterling Capital on the Capital Securities shall be paid on a pro rata basis.
The holders of the Common Securities will be entitled to receive distributions
upon any such liquidation pro rata with the holders of the Capital Securities,
except that if a Debenture Event of Default has occurred and is continuing as a
result of any failure by the Company to pay any amounts in respect of the Junior
Subordinated Debentures when due, the Capital Securities shall have a priority
over the Common Securities. See "-- Subordination of Common Securities."
 
     After the liquidation date fixed for any distribution of Junior
Subordinated Debentures (i) the Capital Securities will no longer be deemed to
be outstanding, (ii) DTC or its nominee, as the registered holder of Capital
Securities, will receive a registered global certificate or certificates
representing the Junior Subordinated Debentures to be delivered upon such
distribution with respect to Capital Securities held by DTC or its nominee and
(iii) any certificates representing the Capital Securities not held by DTC or
its nominee will be deemed to represent the Junior Subordinated Debentures
having a principal amount equal to the stated Liquidation Amount of the Capital
Securities and bearing accrued and unpaid interest in an amount equal to the
accumulated and unpaid Distributions on the Capital Securities until such
certificates are presented to the security registrar for the Trust Securities
for transfer or reissuance.
 
     If the Company does not redeem the Junior Subordinated Debentures prior to
maturity and Sterling Capital is not liquidated and the Junior Subordinated
Debentures are not distributed to holders of the Capital Securities, the Capital
Securities will remain outstanding until the repayment of the Junior
Subordinated Debentures and the distribution of the Liquidation Distribution to
the holders of the Capital Securities.
 
     There can be no assurance as to the market prices for the Capital
Securities or the Junior Subordinated Debentures that may be distributed in
exchange for Capital Securities if a dissolution and liquidation of Sterling
Capital were to occur. Accordingly, the Capital Securities that an investor may
purchase, or the Junior Subordinated Debentures that the investor may receive on
dissolution and liquidation of Sterling Capital, may trade at a discount to the
price that the investor paid to purchase the Capital Securities offered hereby.
 
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 Capital Securities
(whatever the reason for such Event of Default and whether it is voluntary or
involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):
 
          (i) the occurrence of a Debenture Event of Default (see "Description
     of Junior Subordinated Debentures -- Debenture Events of Default"); or
 
          (ii) default by Sterling Capital in the payment of any Distribution
     when it becomes due and payable, and continuation of such default for a
     period of 30 days; or
 
          (iii) default by Sterling Capital in the payment of any Redemption
     Price of any Trust Security when it becomes due and payable; or
 
          (iv) default in the performance, or breach, in any material respect,
     of any covenant or warranty of the Sterling Capital 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 clause (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,
 
                                       31
<PAGE>   34
 
     to the Sterling Capital Trustees and the Company by the holders of at least
     25% in aggregate Liquidation Amount of the outstanding Capital 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 if a successor Property Trustee has not
     been appointed within 90 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 Trust Securities and the
Administrators, unless such Event of Default has been cured or waived. The
Company, as Depositor, and the Administrators 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 as a result
of any failure by the Company to pay any amounts in respect of the Junior
Subordinated Debentures when due, the Capital Securities will have a preference
over the Common Securities with respect to payments of any amounts in respect of
the Capital Securities as described above. See "-- Subordination of Common
Securities," "-- Liquidation Distribution Upon Dissolution" and "Description of
Junior Subordinated Debentures -- Debenture Events of Default."
 
REMOVAL OF STERLING CAPITAL TRUSTEES; APPOINTMENT OF SUCCESSORS
 
     The holders of at least a majority in aggregate Liquidation Amount of the
outstanding Capital Securities may remove a Sterling Capital Trustee for cause
or, if a Debenture Event of Default has occurred and is continuing, with or
without cause. If a Sterling Capital Trustee is removed by the holders of the
outstanding Capital Securities, the successor may be appointed by the holders of
at least 25% in Liquidation Amount of Capital Securities. If a Sterling Capital
Trustee resigns, such Trustee will appoint its successor. If a Sterling Capital
Trustee fails to appoint a successor, the holders of at least 25% in Liquidation
Amount of the outstanding Capital Securities may appoint a successor. If a
successor has not been appointed by the holders, any holder of Capital
Securities or Common Securities or the other Sterling Capital Trustee may
petition a court in the State of Delaware to appoint a successor. Any Delaware
Trustee must meet the applicable requirements of Delaware law. Any Property
Trustee must be a national or state-chartered bank, and at the time of
appointment have securities rated in one of the three highest rating categories
by a nationally recognized statistical rating organization and have capital and
surplus of at least $50.0 million. No resignation or removal of a Sterling
Capital Trustee and no appointment of a successor trustee shall be effective
until the acceptance of appointment by the successor trustee in accordance with
the provisions of the Trust Agreement.
 
MERGER OR CONSOLIDATION OF STERLING CAPITAL TRUSTEES
 
     Any entity into which the Property Trustee or the Delaware Trustee may be
merged or converted or with which it may be consolidated, or any entity
resulting from any merger, conversion or consolidation to which such Sterling
Capital Trustee is a party, or any entity succeeding to all or substantially all
the corporate trust business of such Sterling Capital Trustee, will be the
successor of such Sterling Capital Trustee under the Trust Agreement, provided
such entity is otherwise qualified and eligible.
 
MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF STERLING CAPITAL
 
     Sterling Capital 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 entity, except as described below or as
otherwise set forth in the Trust Agreement. Sterling Capital may, at the request
of the holders of the Common Securities and with the consent of the holders of
at least a majority in aggregate Liquidation Amount of the outstanding Capital
Securities, 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, so long as (i) such
successor entity either (a) expressly assumes all the obligations of Sterling
Capital with respect to the Capital Securities or (b) substitutes for the
Capital
 
                                       32
<PAGE>   35
 
Securities other securities having substantially the same terms as the Capital
Securities (the "Successor Securities") so long as the Successor Securities have
the same priority as the Capital Securities with respect to distributions and
payments upon liquidation, redemption and otherwise, (ii) a trustee of such
successor entity, possessing the same powers and duties as the Property Trustee,
is appointed to hold the Junior Subordinated Debentures, (iii) such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
cause the Capital Securities (including any Successor Securities) to be
downgraded by any nationally recognized statistical rating organization, if then
rated, (iv) such merger, consolidation, amalgamation, replacement, conveyance,
transfer or lease does not adversely affect the rights, preferences and
privileges of the holders of the Capital Securities (including any Successor
Securities) in any material respect, (v) such successor entity has a purpose
substantially identical to that of Sterling Capital, (vi) prior to such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease,
Sterling Capital has received an opinion from independent counsel experienced in
such matters 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 Capital Securities (including
any Successor Securities) in any material respect and (b) following such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease, neither
Sterling Capital nor such successor entity will be required to register as an
investment company under the Investment Company Act, and (vii) the Company or
any permitted successor or assignee owns all 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.
Notwithstanding the foregoing, Sterling Capital may not, except with the consent
of holders of 100% in aggregate Liquidation Amount of the Capital Securities,
consolidate, amalgamate, merge with or into, or be replaced by or convey,
transfer or lease its properties and assets substantially as an entirety to, any
other entity or permit any other entity to consolidate, amalgamate, merge with
or into, or replace it if such consolidation, amalgamation, merger, replacement,
conveyance, transfer or lease would cause Sterling Capital or the successor
entity to be taxable as a corporation for United States federal income tax
purposes.
 
VOTING RIGHTS; AMENDMENT OF TRUST AGREEMENT
 
     Except as provided below and under "-- Removal of Sterling Capital
Trustees; Appointment of Successors" and "Description of Guarantee -- Amendments
and Assignment" and as otherwise required by law and the Trust Agreement, the
holders of the Capital Securities will have no voting rights.
 
     The Trust Agreement may be amended from time to time by the holders of a
majority of the Common Securities and the Property Trustee, without the consent
of the holders of the Capital Securities, (i) to cure any ambiguity, correct or
supplement any provisions in the Trust Agreement that may be inconsistent with
any other provision, or to make any other provisions with respect to matters or
questions arising under the Trust Agreement, provided that any such amendment
does not adversely affect in any material respect the interests of any holder of
Trust Securities, or (ii) to modify, eliminate or add to any provisions of the
Trust Agreement to such extent as may be necessary to ensure that Sterling
Capital will not be taxable as a corporation for United States federal income
tax purposes at any time that any Trust Securities are outstanding or to ensure
that Sterling Capital will not be required to register as an "investment
company" under the Investment Company Act, and any amendments of the Trust
Agreement will become effective when notice of such amendment is given to the
holders of Trust Securities. The Trust Agreement may be amended by the holders
of a majority of the Common Securities and the Property Trustee with (i) the
consent of holders representing not less than a majority in aggregate
Liquidation Amount of the outstanding Capital Securities and (ii) receipt by the
Sterling Capital Trustees of an opinion of counsel to the effect that such
amendment or the exercise of any power granted to the Sterling Capital Trustees
in accordance with such amendment will not affect Sterling Capital's not being
taxable as a corporation for United States federal income tax purposes or
Sterling Capital's exemption from status as an "investment company" under the
Investment Company Act, except that, without the consent of each holder of Trust
Securities affected thereby, the 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 holder of Trust Securities to institute suit for the enforcement of
any such payment on or after such date.

     So long as any Junior Subordinated Debentures are held by Sterling Capital,
the Property Trustee will not (i) direct the time, method and place of
conducting any proceeding for any remedy available to the Debenture Trustee, or
execute any trust or power conferred on the Property Trustee with respect to the
Junior Subordinated Debentures, (ii) waive any past default that is waivable
under Section 5.13 of the Junior Subordinated Indenture, (iii) exercise any
right to rescind or annul a declaration that the Junior Subordinated Debentures
shall be due and payable or (iv) consent to any amendment, modification or
termination of the Junior Subordinated Indenture or the Junior Subordinated
Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the holders of at least a majority in aggregate
Liquidation Amount of the outstanding Capital Securities, except that, if a
consent under the Junior Subordinated Indenture would require the consent of
each holder of Junior Subordinated Debentures affected thereby, no such consent
will be given by the Property Trustee without the prior consent of each holder
of the Capital Securities. The Property Trustee may not revoke any action
previously authorized or approved by a vote of the holders of the Capital
Securities except by subsequent vote of the holders of the Capital Securities.
The Property Trustee will notify each holder of Capital Securities of any notice
of default with respect to the Junior Subordinated Debentures. In addition to
obtaining the foregoing approvals of the holders of the Capital Securities,
before taking any of the foregoing actions, the Property Trustee will obtain an
opinion of counsel experienced in such matters to the effect that Sterling
Capital will not be taxable as a corporation for United States federal income
tax purposes on account of such action.
 
     Any required approval of holders of Capital Securities may be given at a
meeting of holders of Capital Securities convened for such purpose or pursuant
to written consent. The Property Trustee will cause a notice of any meeting at
which holders of Capital Securities are entitled to vote, or of any matter upon
which action by written consent of such holders is to be taken, to be given to
each registered holder of Capital Securities in the manner set forth in the
Trust Agreement.
 
     No vote or consent of the holders of Capital Securities will be required to
redeem and cancel Capital Securities in accordance with the Trust Agreement.
 
     Notwithstanding that holders of Capital Securities are entitled to vote or
consent under any of the circumstances described above, any of the Capital
Securities that are owned by the Company, the Sterling Capital Trustees or any
affiliate of the Company or any Sterling Capital Trustees, will, for purposes of
such vote or consent, be treated as if they were not outstanding.
 
EXPENSES AND TAXES
 
     In the Junior Subordinated Indenture, the Company, as borrower, has agreed
to pay all debts and other obligations (other than with respect to the Capital
Securities) and all costs and expenses of Sterling Capital (including costs and
expenses relating to the organization of Sterling Capital, the fees and expenses
of the Trustees and the costs and expenses relating to the operation of Sterling
Capital) and to pay any and all taxes and all costs and expenses with respect
thereto (other than United States withholding taxes) to which Sterling Capital
might become subject. The foregoing obligations of the Company under the Junior
Subordinated Indenture are for the benefit of, and shall be enforceable by, any
person to whom any such debts, obligations, costs, expenses and taxes are owed
(a "Creditor") whether or not such Creditor has received notice thereof. Any
such Creditor may enforce such obligations of the Company directly against the
Company, and the Company has irrevocably waived any right or remedy to require
that any such Creditor take any action against Sterling Capital or any other
person before proceeding against the Company. The Company has also agreed in the
Junior Subordinated Indenture to execute such additional agreements as may be
necessary or desirable to give full effect to the foregoing.
 
BOOK ENTRY, DELIVERY AND FORM
 
     The Capital Securities will be issued in the form of one or more fully
registered global securities which will be deposited with, or on behalf of, DTC
and registered in the name of DTC's nominee. Unless and until it is exchangeable
in whole or in part for the Capital Securities in definitive form, a global
security may not be transferred except as a whole by DTC to a nominee of DTC or
by a nominee of DTC to DTC or another
 
                                       34
<PAGE>   37
 
nominee of DTC or by DTC or any such nominee to a successor of such Depository
or a nominee of such successor.
 
     Ownership of beneficial interests in a global security will be limited to
persons that have accounts with DTC or its nominee ("Participants") or persons
that may hold interests through Participants. The Company expects that, upon the
issuance of a global security, DTC will credit, on its book-entry registration
and transfer system, the Participants' accounts with their respective principal
amounts of the Capital Securities represented by such global security. Ownership
of beneficial interests in such global security will be shown on, and the
transfer of such ownership interests will be effected only through, records
maintained by DTC (with respect to interests of Participants) and on the records
of Participants (with respect to interests of persons held through
Participants). Beneficial owners will not receive written confirmation from DTC
of their purchase, but are expected to receive written confirmations from the
Participants through which the beneficial owner entered into the transaction.
Transfers of ownership interests will be accomplished by entries on the books of
Participants acting on behalf of the beneficial owners.
 
     So long as DTC, or its nominee, is the registered owner of a global
security, DTC or such nominee, as the case may be, will be considered the sole
owner or holder of the Capital Securities represented by such global security
for all purposes under the Junior Subordinated Indenture. Except as provided
below, owners of beneficial interests in a global security will not be entitled
to receive physical delivery of the Capital Securities in definitive form and
will not be considered the owners or holders thereof under the Junior
Subordinated Indenture. Accordingly, each person owning a beneficial interest in
such a global security must rely on the procedures of DTC and, if such person is
not a Participant, on the procedures of the Participant through which such
person owns its interest, to exercise any rights of a holder of Capital
Securities under the Junior Subordinated Indenture. The Company understands
that, under DTC's existing practices, in the event that the Company requests any
action of holders, or an owner of a beneficial interest in such a global
security desires to take any action which a holder is entitled to take under the
Junior Subordinated Indenture, DTC would authorize the Participants holding the
relevant beneficial interests to take such action, and such Participants would
authorize beneficial owners owning through such Participants to take such action
or would otherwise act upon the instructions of beneficial owners owning through
them. Redemption notices will also be sent to DTC. If less than all of the
Capital Securities are being redeemed, the Company understands that it is DTC's
existing practice to determine by lot the amount of the respective holdings of
each Participant to be redeemed.
 
     Distributions on the Capital Securities registered in the name of DTC or
its nominee will be made to DTC or its nominee, as the case may be, as the
registered owner of the global security representing such Capital Securities.
None of the Company, the Trustees, the Administrators, any Paying Agent or any
other agent of the Company or the Trustees will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in the global security for such Capital
Securities or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests. Disbursements of Distributions to
Participants shall be the responsibility of DTC. DTC's practice is to credit
Participants' accounts on a payable date in accordance with their respective
holdings shown on DTC's records unless DTC has reason to believe that it will
not receive payment on the payable date. Payments by Participants to beneficial
owners will be governed by standing instructions and customary practices, as is
the case with securities held for the accounts of customers in bearer form or
registered in "street name," and will be the responsibility of such Participant
and not of DTC, the Company, the Trustees, the Paying Agent or any other agent
of the Company, subject to any statutory or regulatory requirements as may be in
effect from time to time.
 
     DTC may discontinue providing its services as securities depository with
respect to the Capital Securities at any time by giving reasonable notice to the
Company or the Trustees. If DTC notifies the Company that it is unwilling to
continue as such, or if it is unable to continue or ceases to be a clearing
agency registered under the Exchange Act and a successor depository is not
appointed by the Company within ninety days after receiving such notice or
becoming aware that DTC is no longer so registered, the Company will issue the
Capital Securities in definitive form upon registration of transfer of, or in
exchange for, such global security. In addition, the Company may at any time and
in its sole discretion determine not to have the Capital Securities
 
                                       35
<PAGE>   38
 
represented by one or more global securities and, in such event, will issue
Capital Securities in definitive form in exchange for all of the global
securities representing such Capital Securities.
 
     DTC has advised the Company and Sterling Capital as follows: DTC is a
limited purpose trust company organized under the laws of the State of New York,
a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the Uniform Commercial Code and a "clearing agency" registered
pursuant to the provisions of Section 17A of the Exchange Act. DTC was created
to hold securities for its Participants and to facilitate the clearance and
settlement of securities transactions between Participants through electronic
book entry changes to accounts of its Participants, thereby eliminating the need
for physical movement of certificates. Participants include securities brokers
and dealers (such as the Underwriters), banks, trust companies and clearing
corporations and may include certain other organizations. Certain of such
Participants (or their representatives), together with other entities, own DTC.
Indirect access to the DTC system is available to others such as banks, brokers,
dealers and trust companies that clear through, or maintain a custodial
relationship with a Participant, either directly or indirectly.
 
PAYMENT AND PAYING AGENCY
 
     Payments in respect of the Capital Securities will be made to DTC, which
will credit the relevant accounts at DTC on the applicable Distribution Dates
or, if the Capital Securities are not held by DTC, such payments will be made by
check mailed to the address of the holder entitled thereto as such address
appears on the securities register for the Trust Securities. The paying agent
(the "Paying Agent") will initially be the Property Trustee and any co-paying
agent chosen by the Property Trustee and acceptable to the Administrators. The
Paying Agent will be permitted to resign as Paying Agent upon 30 days written
notice to the Property Trustee and the Administrators. If the Property Trustee
is no longer the Paying Agent, the Property Trustee will appoint a successor
(which must be a bank or trust company reasonably acceptable to the
Administrators) to act as Paying Agent.
 
REGISTRAR AND TRANSFER AGENT
 
     The Property Trustee will act as registrar and transfer agent for the
Capital Securities. Registration of transfers of Capital Securities will be
effected without charge by or on behalf of Sterling Capital, but upon payment of
any tax or other governmental charges that may be imposed in connection with any
transfer or exchange. Sterling Capital will not be required to register or cause
to be registered the transfer of the Capital Securities after the Capital
Securities have been called for redemption.
 
INFORMATION CONCERNING THE PROPERTY TRUSTEE
 
     The Property Trustee, other than during the occurrence and continuance of
an Event of Default, undertakes to perform only such duties as are specifically
set forth in the Trust Agreement and, after such 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 Capital Securities unless it is
offered reasonable indemnity against the costs, expenses and liabilities that
might be incurred thereby. For information concerning the relationships between
Bankers Trust Company, the Property Trustee, and the Company, see "Description
of Junior Subordinated Debentures -- Information Concerning the Debenture
Trustee."
 
MISCELLANEOUS
 
     The Administrators and the Property Trustee are authorized and directed to
conduct the affairs of and to operate Sterling Capital in such a way that
Sterling Capital will not be deemed to be an "investment company" required to be
registered under the Investment Company Act or taxable as a corporation for
United States federal income tax purposes and so that the Junior Subordinated
Debentures will be treated as indebtedness of the Company for United States
federal income tax purposes. In this connection, the Property Trustee and the
holders of Common Securities are authorized to take any action, not inconsistent
with
 
                                       36
<PAGE>   39
 
applicable law, the certificate of trust of Sterling Capital or the Trust
Agreement, that the Property Trustee and the holders of Common Securities
determine in their discretion to be necessary or desirable for such purposes, as
long as such action does not materially adversely affect the interests of the
holders of the Capital Securities. Holders of the Capital Securities have no
preemptive or similar rights.
 
     Sterling Capital may not borrow money, issue debt or mortgage or pledge any
of its assets.
 
GOVERNING LAW
 
     The Trust Agreement will be governed by and construed in accordance with
the laws of the State of Delaware.
 
                 DESCRIPTION OF JUNIOR SUBORDINATED DEBENTURES
 
     The Junior Subordinated Debentures are to be issued under the Junior
Subordinated Indenture dated as of          , 1997, under which Bankers Trust
Company is acting as Debenture Trustee. This summary of certain terms and
provisions of the Junior Subordinated Debentures and the Junior Subordinated
Indenture does not purport to be complete and is subject to, and is qualified in
its entirety by reference to, all the provisions of the Junior Subordinated
Indenture, including the definitions therein of certain terms. Whenever
particular defined terms of the Junior Subordinated Indenture (as amended or
supplemented from time to time) are referred to herein, such defined terms are
incorporated herein by reference. A copy of the form of Junior Subordinated
Indenture is available from the Debenture Trustee upon request.
 
GENERAL
 
     Concurrently with the issuance of the Capital Securities, Sterling Capital
will invest the proceeds thereof, together with the consideration paid by the
Company for the Common Securities, in the Junior Subordinated Debentures issued
by the Company. The Junior Subordinated Debentures will bear interest, accruing
from the date of original issuance, at the annual rate of      % of the
principal amount thereof, payable quarterly in arrears on September 30, December
31, March 31 and June 30 of each year (each, an "Interest Payment Date"),
commencing September 30, 1997, to the person in whose name each Junior
Subordinated Debenture is registered at the close of business on September 15,
December 15, March 15 and June 15 (whether or not a Business Day) next preceding
such Interest Payment Date. It is anticipated that, until the liquidation, if
any, of Sterling Capital, each Junior Subordinated Debenture will be registered
in the name of Sterling Capital and held by the Property Trustee in trust for
the benefit of the holders of the Trust Securities. The amount of interest
payable for any period less than a full interest period will be computed on the
basis of a 360-day year of twelve 30-day months and the actual days elapsed in a
partial month in such period. The amount of interest payable for any full
interest period will be computed by dividing the rate per annum by four. If any
date on which interest is payable on the Junior 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 (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
     %, compounded quarterly and computed on the basis of a 360-day year of
twelve 30-day months and the actual days elapsed in a partial month in such
period. The amount of additional interest payable for any full interest period
will be computed by dividing the rate per annum by four. 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 Sums
(as defined below), as applicable.
 
     The Junior Subordinated Debentures will mature on             , 2027, which
date may be shortened (such date, as it may be shortened, the "Stated Maturity")
to a date not earlier than             , 2002, if certain conditions are met,
including 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 that the Company elects to shorten the Stated
Maturity of the Junior Subordinated Debentures, it will give notice to the
registered holders of the Junior Subordinated Debentures, the Property Trustee
and the Indenture Trustee
 
                                       37
<PAGE>   40
 
of such shortening no less than 90 days prior to the effectiveness thereof. The
Property Trustee must give notice to the holders of the Trust Securities of the
shortening of the Stated Maturity.
 
     The Junior Subordinated Debentures will be unsecured and will rank junior
and be subordinate in right of payment to all Senior Indebtedness of the
Company. The Junior Subordinated Debentures will not be subject to a sinking
fund. The Junior Subordinated Indenture does not limit the incurrence or
issuance of other secured or unsecured debt by the Company, including Senior
Indebtedness, whether under the Junior Subordinated Indenture or any existing or
other indenture that the Company may enter into in the future or otherwise. See
"-- Subordination."
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD
 
   
     So long as no Debenture Event of Default has occurred and is continuing,
the Company has the right at any time during the term of the Junior Subordinated
Debentures to defer the payment of interest at any time or from time to time for
a period not exceeding 20 consecutive quarterly periods with respect to each
Extension Period, provided that no Extension Period may extend beyond the Stated
Maturity of the Junior Subordinated Debentures. During any such Extension Period
the Company shall have the right to make partial payments of interest on any
interest payment date. At the end of such Extension Period, the Company must pay
all interest then accrued and unpaid (together with interest thereon at the
annual rate of      %, compounded quarterly and computed on the basis of a
360-day year of twelve 30-day months and the actual days elapsed in a partial
month in such period, to the extent permitted by applicable law). The amount of
additional interest payable for any full interest period will be computed by
dividing the rate per annum by four. During an Extension Period, interest will
continue to accrue and holders of Junior Subordinated Debentures (or holders of
Capital Securities while outstanding) will be required to accrue income for
United States federal income tax purposes. See "Certain Federal Income Tax
Consequences -- US Holders -- Interest Income 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 or (ii)
make any payment of principal of or interest or premium, if any, on or repay,
repurchase or redeem any debt securities of the Company that rank pari passu in
all respects with or junior in interest to the Junior Subordinated Debentures
(other than (a) repurchases, redemptions or other acquisitions of shares of
capital stock of the Company in connection with any employment contract, benefit
plan or other similar arrangement with or for the benefit of any one or more
employees, officers, directors or consultants, in connection with a dividend
reinvestment or stockholder stock purchase plan or in connection with the
issuance of capital stock of the Company (or securities convertible into or
exercisable for such capital stock) as consideration in an acquisition
transaction entered into prior to the applicable Extension Period, (b) as a
result of an exchange or conversion of any class or series of the Company's
capital stock (or any capital stock of a subsidiary of the Company) for any
class or series of the Company's capital stock or of any class or series of the
Company's indebtedness for any class or series of the Company's capital stock,
(c) the purchase of fractional interests in shares of the Company's capital
stock pursuant to the conversion or exchange provisions of such capital stock or
the security being converted or exchanged, (d) any declaration of a dividend in
connection with any stockholder's rights plan, or the issuance of rights, stock
or other property under any stockholders rights plan, or the redemption or
repurchase of rights pursuant thereto, or (e) any dividend in the form of stock,
warrants, options or other rights where the dividend stock or the stock issuable
upon exercise of such warrants, options or other rights is the same stock as
that on which the dividend is being paid or ranks pari passu with or junior to
such stock). 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 quarterly periods or extend beyond the Stated Maturity of
the Junior 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 conditions. No interest shall be due
and payable during an Extension Period, except at the end thereof. The Company
must give the Sterling Capital Trustees notice of its election of such Extension
Period at least one Business Day prior to the earlier of (i) the date the
Distributions on the Capital Securities would have been payable but for the
election to begin such Extension
 
                                       38
<PAGE>   41
 
Period and (ii) the date the Property Trustee is required to give notice to
holders of the Capital Securities of the record date or the date such
Distributions are payable, but in any event not less than one Business Day prior
to such record date. The Property Trustee will give notice of the Company's
election to begin a new Extension Period to the holders of the Capital
Securities. There is no limitation on the number of times that the Company may
elect to begin an Extension Period.
 
REDEMPTION
 
     The Junior Subordinated Debentures are redeemable prior to maturity at the
option of the Company (i) on or after          , 2002, in whole at any time or
in part from time to time, or (ii) in whole, but not in part, at any time within
90 days following the occurrence and during the continuation of a Tax Event,
Investment Company Event or Capital Treatment Event (each as defined under
"Description of Capital Securities -- Redemption"), in each case at the
Redemption Price. The proceeds of any such redemption will be used by Sterling
Capital to redeem the Capital Securities.
 
     The Federal Reserve's risk-based capital guidelines, which are subject to
change, currently provide that redemptions of permanent equity or other capital
instruments before Stated Maturity could have a significant impact on a bank
holding company's overall capital structure and that any organization
considering such a redemption should consult with the Federal Reserve before
redeeming any equity or capital instrument prior to maturity if such redemption
could have a material effect on the level or composition of the organization's
capital base (unless the equity or capital instrument were redeemed with the
proceeds of, or replaced by, a like amount of a similar or higher quality
capital instrument and the Federal Reserve considers the organization's capital
position to be fully adequate after the redemption).
 
     The redemption of the Junior Subordinated Debentures by the Company prior
to their Stated Maturity would constitute the redemption of capital instruments
under the Federal Reserve's current risk-based capital guidelines and may be
subject to the prior approval of the Federal Reserve. The redemption of the
Junior Subordinated Debentures also could be subject to the additional prior
approval of the Federal Reserve under its current risk-based capital guidelines.
 
     The Redemption Price for Junior Subordinated Debentures is the outstanding
principal amount of the Junior Subordinated Debentures plus accrued interest
(including any Additional Interest or Additional Sums) thereon to but excluding
the date fixed for redemption.
 
ADDITIONAL SUMS
 
     The Company has covenanted in the Junior Subordinated Indenture that, if
and for so long as (i) Sterling Capital is the holder of all Junior Subordinated
Debentures and (ii) Sterling Capital is required to pay any additional taxes,
duties or other governmental charges as a result of a Tax Event, the Company
will pay as additional sums on the Junior Subordinated Debentures such amounts
as may be required so that the Distributions payable by Sterling Capital will
not be reduced as a result of any such additional taxes, duties or other
governmental charges. See "Description of Capital Securities -- Redemption."
 
REGISTRATION, DENOMINATION AND TRANSFER
 
     The Junior Subordinated Debentures will initially be registered in the name
of Sterling Capital. If the Junior Subordinated Debentures are distributed to
holders of Capital Securities, it is anticipated that the depositary
arrangements for the Junior Subordinated Debentures will be substantially
identical to those in effect for the Capital Securities. See "Description of
Capital Securities -- Book Entry, Delivery and Form."
 
     Although DTC has agreed to the procedures described above, it is under no
obligation to perform or continue to perform such procedures, and such
procedures may be discontinued at any time. If DTC is at any time unwilling or
unable to continue as depositary and a successor depositary is not appointed by
the Company within 90 days of receipt of notice from DTC to such effect, the
Company will cause the Junior Subordinated Debentures to be issued in definitive
form.
 
                                       39
<PAGE>   42
 
     Payments on Junior Subordinated Debentures represented by a global security
will be made to Cede & Co., the nominee for DTC, as the registered holder of the
Junior Subordinated Debentures, as described under "Description of the Capital
Securities -- Book Entry, Delivery and Form." If Junior Subordinated Debentures
are issued in certificated form, principal and interest will be payable, the
transfer of the Junior Subordinated Debentures will be registrable, and Junior
Subordinated Debentures will be exchangeable for Junior Subordinated Debentures
of other authorized denominations of a like aggregate principal amount, at the
corporate trust office of the Debenture Trustee in New York, New York or at the
offices of any Paying Agent or transfer agent appointed by the Company, provided
that payment of interest may be made at the option of the Company by check
mailed to the address of the persons entitled thereto. However, a holder of $1.0
million or more in aggregate principal amount of Junior Subordinated Debentures
may receive payments of interest (other than interest payable at the Stated
Maturity) by wire transfer of immediately available funds upon written request
to the Debenture Trustee not later than 15 calendar days prior to the date on
which the interest is payable.
 
     Junior Subordinated Debentures will be exchangeable for other Junior
Subordinated Debentures of like tenor, of any authorized denominations, and of a
like aggregate principal amount.
 
     Junior Subordinated Debentures may be presented for exchange as provided
above, and 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 securities registrar appointed under the
Junior Subordinated Debenture or at the office of any transfer agent designated
by the Company for such purpose without service charge and upon payment of any
taxes and other governmental charges as described in the Junior Subordinated
Indenture. The Company will appoint the Debenture Trustee as securities
registrar under the Junior Subordinated Indenture. The Company may at any time
designate additional transfer agents with respect to the Junior Subordinated
Debentures.
 
     In the event of any redemption, neither the Company nor the Debenture
Trustee shall be required to (i) issue, register the transfer of or exchange
Junior Subordinated Debentures during a period beginning at the opening of
business 15 days before the day of selection for redemption of the Junior
Subordinated Debentures to be redeemed and ending at the close of business on
the day of mailing of the relevant notice of redemption or (ii) transfer or
exchange any Junior Subordinated Debentures so selected for redemption, except,
in the case of any Junior Subordinated Debentures being redeemed in part, any
portion thereof not to be redeemed.
 
     Any monies deposited with the Debenture Trustee or any paying agent, or
then held by the Company in trust, for the payment of the principal of or
interest on any Junior Subordinated Debenture and remaining unclaimed for two
years after such principal or interest has become due and payable shall, at the
request of the Company, be repaid to the Company and the holder of such Junior
Subordinated Debenture shall thereafter look, as a general unsecured creditor,
only to the Company for payment thereof.
 
RESTRICTIONS ON CERTAIN PAYMENTS; CERTAIN COVENANTS OF THE COMPANY
 
     The Company has covenanted that it will not (i) declare or pay any
dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Company's capital stock or (ii)
make any payment of principal of or interest on or repay, repurchase or redeem
any debt securities of the Company that rank pari passu in all respects with or
junior in interest to the Junior Subordinated Debentures (other than (a)
repurchases, redemptions or other acquisitions of shares of capital stock of the
Company in connection with any employment contract, benefit plan or other
similar arrangement with or for the benefit of any one or more employees,
officers, directors or consultants, in connection with a dividend reinvestment
or stockholder stock purchase plan or in connection with the issuance of capital
stock of the Company (or securities convertible into or exercisable for such
capital stock) as consideration in an acquisition transaction entered into prior
to the applicable Extension Period or other event referred to below, (b) as a
result of an exchange or conversion of any class or series of the Company's
capital stock (or any capital stock of a subsidiary of the Company) for any
class or series of the Company's capital stock or of any class or series of the
Company's indebtedness for any class or series of the Company's capital stock,
(c) the purchase of fractional interests in shares of the Company's capital
stock pursuant to the conversion or

exchanged, (d) any declaration of a dividend in connection with any
stockholder's rights plan, or the issuance of rights, stock or other property
under any stockholder's rights plan, or the redemption or repurchase of rights
pursuant thereto, or (e) any dividend in the form of stock, warrants, options or
other rights where the dividend stock or the stock issuable upon exercise of
such warrants, options or other rights is the same stock as that on which the
dividend is being paid or ranks pari passu with or junior to such stock), if at
such time (i) there has occurred any event (a) of which the Company has actual
knowledge that with the giving of notice or the lapse of time, or both, would
constitute a Debenture Event of Default and (b) that the Company has not taken
reasonable steps to cure, (ii) if the Junior Subordinated Debentures are held by
Sterling Capital, the Company is in default with respect to its payment of any
obligations under the Guarantee or (iii) the Company has given notice of its
election of an Extension Period as provided in the Junior Subordinated Indenture
and has not rescinded such notice, or such Extension Period, or any extension
thereof, is continuing.
 
     The Company has covenanted in the Junior Subordinated Indenture (i) to
continue to hold, directly or indirectly, 100% of the Common Securities,
provided that certain successors that are permitted pursuant to the Junior
Subordinated Indenture may succeed to the Company's ownership of the Common
Securities, (ii) as holder of the Common Securities, not to voluntarily
terminate, windup or liquidate Sterling Capital, other than (a) in connection
with a distribution of Junior Subordinated Debentures to the holders of the
Capital Securities in liquidation of Sterling Capital 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 Sterling Capital to continue not to
be taxable as a corporation for United States federal income tax purposes.
 
MODIFICATION OF JUNIOR SUBORDINATED INDENTURE
 
     From time to time, the Company and the Debenture Trustee may, without the
consent of any of the holders of the outstanding Junior Subordinated Debentures,
amend, waive or supplement the provisions of the Junior Subordinated Indenture
to: (1) evidence succession of another corporation or association to the Company
and the assumption by such person of the obligations of the Company under the
Junior Subordinated Debentures, (2) add further covenants, restrictions or
conditions for the protection of holders of the Junior Subordinated Debentures,
(3) cure ambiguities or correct the Junior Subordinated Debentures in the case
of defects or inconsistencies in the provisions thereof, so long as any such
cure or correction does not adversely affect the interest of the holders of the
Junior Subordinated Debentures in any material respect, (4) change the terms of
the Junior Subordinated Debentures to facilitate the issuance of the Junior
Subordinated Debentures in certificated or other definitive form, (5) evidence
or provide for the appointment of a successor Debenture Trustee, or (6) qualify,
or maintain the qualification of, the Junior Subordinated Indentures under the
Trust Indenture Act. The Junior Subordinated 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 Junior
Subordinated Debentures, to modify the Junior Subordinated Indenture in a manner
affecting the rights of the holders of the Junior Subordinated Debentures,
except that no such modification may, without the consent of the holder of each
outstanding Junior Subordinated Debenture so affected, (i) change the Stated
Maturity of the Junior Subordinated Debentures (except as described under
"-- General"), or reduce the principal amount thereof, the rate of interest
thereon, or change the place of payment where, or the currency in which, any
such amount is payable or impair the right to institute suit for the enforcement
of any Junior Subordinated Debenture or (ii) reduce the percentage of principal
amount of Junior Subordinated Debentures, the holders of which are required to
consent to any such modification of the Junior Subordinated Indenture.
Furthermore, so long as any of the Capital Securities remain outstanding, no
such modification may be made that adversely affects the holders of such Capital
Securities in any material respect, and no termination of the Junior
Subordinated Indenture may occur, and no waiver of any Debenture Event of
Default or compliance with any covenant under the Junior Subordinated Indenture
may be effective, without the prior consent of the holders of at least a
majority of the aggregate Liquidation Amount of the outstanding Capital
Securities unless and until the principal of the Junior Subordinated Debentures
and all accrued and unpaid interest thereon have been paid in full and certain
other conditions are satisfied.

DEBENTURE EVENTS OF DEFAULT
 
     The Junior Subordinated Indenture provides that any one or more of the
following described events with respect to the Junior Subordinated Debentures
that has occurred and is continuing constitutes an "Event of Default" with
respect to the Junior Subordinated Debentures:
 
          (i) failure to pay any interest on the Junior Subordinated Debentures
     when due (subject to the deferral of any due date in the case of an
     Extension Period); or
 
          (ii) failure to pay any principal on the Junior Subordinated
     Debentures when due whether at maturity, upon redemption, by declaration of
     acceleration or otherwise; or
 
          (iii) failure to observe or perform in any material respect certain
     other covenants contained in the Junior Subordinated 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
     outstanding Junior Subordinated Debentures; or
 
          (iv) the Company consents to the appointment of a receiver or other
     similar official in any liquidation, insolvency or similar proceeding with
     respect to the Company or all or substantially all its property.
 
     For purposes of the Trust Agreement and this Prospectus, each such Event of
Default under the Junior Subordinated Debenture is referred to as a "Debenture
Event of Default." As described in "Description of Capital Securities -- Events
of Default; Notice," the occurrence of a Debenture Event of Default will also
constitute an Event of Default in respect of the Trust Securities.
 
     The holders of at least a majority in aggregate principal amount of
outstanding Junior 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 principal amount of outstanding Junior Subordinated Debentures may
declare the principal due and payable immediately upon a Debenture Event of
Default, and, should the Debenture Trustee or such holders of Junior
Subordinated Debentures fail to make such declaration, the holders of at least
25% in aggregate Liquidation Amount of the outstanding Capital Securities shall
have such right. The holders of a majority in aggregate principal amount of
outstanding Junior Subordinated Debentures may annul such declaration and waive
the default if all defaults (other than the non-payment of the principal of
Junior Subordinated Debentures which has become due solely by such acceleration)
have 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 Junior Subordinated Debentures fail to
annul such declaration and waive such default, the holders of a majority in
aggregate Liquidation Amount of the outstanding Capital Securities shall have
such right.
 
     The holders of at least a majority in aggregate principal amount of the
outstanding Junior Subordinated Debentures affected thereby may, on behalf of
the holders of all the Junior Subordinated Debentures, waive any past default,
except a default in the payment of principal or interest (unless such default
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) or a default in respect of a covenant or provision which
under the Junior Subordinated Indenture cannot be modified or amended without
the consent of the holder of each outstanding Junior Subordinated Debenture
affected thereby. See "-- Modification of Junior Subordinated Indenture." 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 Junior Subordinated Indenture.
 
     If a Debenture Event of Default occurs and is continuing, the Property
Trustee will have the right to declare the principal of and the interest on the
Junior Subordinated Debentures, and any other amounts payable under the Junior
Subordinated Indenture, to be forthwith due and payable and to enforce its other
rights as a creditor with respect to the Junior Subordinated Debentures.

ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF CAPITAL 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 any amounts payable
in respect of the Junior Subordinated Debentures on the date such amounts are
otherwise payable, a registered holder of Capital Securities may institute a
Direct Action against the Company for enforcement of payment to such holder of
an amount equal to the amount payable in respect of Junior Subordinated
Debentures having a principal amount equal to the aggregate Liquidation Amount
of the Capital Securities held by such holder. The Company may not amend the
Junior Subordinated Indenture to remove the foregoing right to bring a Direct
Action without the prior written consent of the holders of all the Capital
Securities. The Company will have the right under the Junior Subordinated
Indenture to set-off any payment made to such holder of Capital Securities by
the Company in connection with a Direct Action.
 
     The holders of the Capital Securities are not able to exercise directly any
remedies available to the holders of the Junior Subordinated Debentures except
under the circumstances described in the preceding paragraph. See "Description
of Capital Securities -- Events of Default; Notice."
 
CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS
 
   
     The Junior Subordinated Indenture provides that the Company may not
consolidate with or merge into any other person or convey, transfer or lease its
properties and assets substantially as an entirety to any person, and no person
may consolidate with or merge into the Company or convey, transfer or lease its
properties and assets substantially as an entirety to the Company, unless (i) if
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
the Company's obligations in respect of the Junior 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 constitute a Debenture
Event of Default, has occurred and is continuing; and (iii) certain other
conditions as prescribed in the Junior Subordinated Indenture are satisfied.
    
 
     The provisions of the Junior Subordinated Indenture do not afford holders
of the Junior Subordinated Debentures protection in the event of a highly
leveraged or other transaction involving the Company that may adversely affect
holders of the Junior Subordinated Debentures.
 
SATISFACTION AND DISCHARGE
 
     The Junior Subordinated Indenture provides that when, among other things,
all Junior Subordinated Debentures not previously delivered to the Debenture
Trustee for cancellation (i) have become due and payable, (ii) will become due
and payable at the Stated Maturity within one year, or (iii) are to be called
for redemption within one year under arrangements satisfactory to the Debenture
Trustee for the giving of notice of redemption, and, in each case, 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 Junior Subordinated Debentures not previously delivered to
the Debenture Trustee for cancellation, for the principal and interest to the
date of the deposit or to the Stated Maturity, as the case may be, then the
Junior Subordinated Indenture will cease to be of further effect (except as to
the Company's obligations to pay all other sums due pursuant to the Junior
Subordinated Indenture and to provide the officers' certificates and opinions of
counsel described therein), and the Company will be deemed to have satisfied and
discharged the Junior Subordinated Indenture.
 
SUBORDINATION
 
     The Junior Subordinated Debentures will be subordinate and junior in right
of payment, to the extent set forth in the Junior Subordinated Indenture, to all
Senior Indebtedness (as defined below) of the Company. If the Company defaults
in the payment of any principal, or interest, if any, or any other amount
payable on any Senior Indebtedness when the same becomes due and payable,
whether at maturity or at a date fixed for redemption or by declaration of
acceleration or otherwise, then, unless and until such default has been cured
 
                                       43
<PAGE>   46
 
or waived or has ceased to exist or all Senior Indebtedness has been paid, no
direct or indirect payment (in cash, property, securities, by setoff or
otherwise) may be made or agreed to be made on the Junior Subordinated
Debentures, or in respect of any redemption, repayment, retirement, purchase or
other acquisition of any of the Junior Subordinated Debentures.
 
   
     As used herein, "Senior Indebtedness" means, whether recourse is to all or
a portion of the assets of the Company and whether or not contingent, (i) every
obligation of the Company for money borrowed, (ii) every obligation of the
Company 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 the Company with
respect to letters of credit, bankers' acceptances or similar facilities issued
for the account of the Company, (iv) every obligation of the Company 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 the Company, (vi) every
obligation of the Company for claims (as defined in Section 101(4) of the United
States Bankruptcy Code of 1978, as amended) in respect of derivative products
such as interest and foreign exchange rate contracts, commodity contracts and
similar arrangements, and (vii) every obligation of the type referred to in
clauses (i) through (vi) of another person and all dividends of another person
the payment of which, in either case, the Company has guaranteed or is
responsible or liable for, directly or indirectly, as obligor or otherwise,
including, without limitation, the Company's 8.75% Subordinated Notes Due
January 31, 2000 in the aggregate principal amount of $17.2 million and a $15.0
million Term Note Due September 30, 2002; provided that "Senior Indebtedness"
shall not include (i) any obligations which, by their terms, are expressly
stated to rank pari passu in right of payment with, or to not be superior in
right of payment to, the Junior Subordinated Debentures, (ii) any Senior
Indebtedness 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, (iii) any Indebtedness of the
Company to any of its subsidiaries, (iv) Indebtedness to any executive officer
or director of the Company, or (v) any indebtedness in respect of debt
securities issued to any trust, or a trustee of such trust, partnership or other
entity affiliated with the Company that is a financing entity of the Company in
connection with the issuance of such financing entity of securities that are
similar to the Capital Securities.
    
 
     In the event of (i) certain events of bankruptcy, dissolution or
liquidation of the Company or the holder of the Common Securities, (ii) any
proceeding for the liquidation, dissolution or other winding up of the Company,
voluntary or involuntary, whether or not involving insolvency or bankruptcy
proceedings, (iii) any assignment by the Company for the benefit of creditors or
(iv) any other marshalling of the assets of the Company, all Senior Indebtedness
(including any interest thereon accruing after the commencement of any such
proceedings) shall first be paid in full before any payment or distribution,
whether in cash, securities or other property, shall be made on account of the
Junior Subordinated Debentures. In such event, any payment or distribution on
account of the Junior Subordinated Debentures, whether in cash, securities or
other property, that would otherwise (but for the subordination provisions) be
payable or deliverable in respect of the Junior Subordinated Debentures will be
paid or delivered directly to the holders of Senior Indebtedness in accordance
with the priorities then existing among such holders until all Senior
Indebtedness (including any interest thereon accruing after the commencement of
any such proceedings) has been paid in full.
 
     In the event of any such proceeding, after payment in full of all sums
owing with respect to Senior Indebtedness, the holders of Junior Subordinated
Debentures, together with the holders of any obligations of the Company ranking
on a parity with the Junior Subordinated Debentures, will be entitled to be paid
from the remaining assets of the Company the amounts at the time due and owing
on the Junior Subordinated Debentures and such other obligations before any
payment or other distribution, whether in cash, property or otherwise, will be
made on account of any capital stock or obligations of the Company ranking
junior to the Junior Subordinated Debentures and such other obligations. If any
payment or distribution on account of the Junior Subordinated Debentures of any
character or any security, whether in cash, securities or other property is
received by any holder of any Junior Subordinated Debentures in contravention of
any of the terms hereof and before all the Senior Indebtedness has been paid in
full, such payment or distribution or security will be received in trust for the
benefit of, and must be paid over or delivered and transferred to, the holders
of the
 
                                       44
<PAGE>   47
 
Senior Indebtedness at the time outstanding in accordance with the priorities
then existing among such holders for application to the payment of all Senior
Indebtedness remaining unpaid to the extent necessary to pay all such Senior
Indebtedness in full. By reason of such subordination, in the event of the
insolvency of the Company, holders of Senior Indebtedness may receive more,
ratably, and holders of the Junior Subordinated Debentures may receive less,
ratably, than the other creditors of the Company. Such subordination will not
prevent the occurrence of any Event of Default in respect of the Junior
Subordinated Debentures.
 
     The Junior Subordinated Indenture places no limitation on the amount of
additional Senior Indebtedness that may be incurred by the Company. The Company
expects from time to time to incur additional indebtedness constituting Senior
Indebtedness.
 
INFORMATION CONCERNING THE DEBENTURE TRUSTEE
 
     The Debenture Trustee, other than during the occurrence and continuance of
a default by the Company in performance of its obligations under the Junior
Subordinated Debenture, is under no obligation to exercise any of the powers
vested in it by the Junior Subordinated Indenture at the request of any holder
of Junior Subordinated Debentures, unless offered reasonable indemnity by such
holder against the costs, expenses and liabilities that 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.
 
     Bankers Trust Company, the Debenture Trustee, may serve from time to time
as trustee under other indentures or trust agreements with the Company or its
subsidiaries relating to other issues of their securities. In addition, the
Company and certain of its affiliates may have other banking relationships with
Bankers Trust Company and its affiliates.
 
GOVERNING LAW
 
     The Junior Subordinated Indenture and the Junior Subordinated Debentures
will be governed by and construed in accordance with the laws of the State of
New York.
 
                            DESCRIPTION OF GUARANTEE
 
     The Guarantee will be executed and delivered by the Company concurrently
with the issuance of Capital Securities by Sterling Capital for the benefit of
the holders from time to time of the Capital Securities. Bankers Trust Company
will act as Guarantee Trustee under the Guarantee. This summary of certain
provisions of the Guarantee does not purport to be complete and is subject to,
and qualified in its entirety by reference to, all the provisions of the
Guarantee, including the definitions therein of certain terms. A copy of the
form of Guarantee is available upon request from the Guarantee Trustee. The
Guarantee Trustee will hold the Guarantee for the benefit of the holders of the
Capital Securities.
 
GENERAL
 
     The Company will irrevocably agree to pay in full on a subordinated basis,
to the extent set forth herein, the Guarantee Payments (as defined below) to the
holders of the Capital Securities, as and when due, regardless of any defense,
right of set-off or counterclaim that Sterling Capital may have or assert other
than the defense of payment. The following payments with respect to the Capital
Securities, to the extent not paid by or on behalf of Sterling Capital (the
"Guarantee Payments"), will be subject to the Guarantee: (i) any accumulated and
unpaid Distributions required to be paid on such Capital Securities, to the
extent that Sterling Capital has funds on hand available therefor at such time,
(ii) the Redemption Price with respect to any Capital Securities called for
redemption, to the extent that Sterling Capital has funds on hand available
therefor at such time, and (iii) upon a voluntary or involuntary dissolution, of
Sterling Capital (unless the Junior Subordinated Debentures are distributed to
holders of the Capital Securities), the lesser of (a) the aggregate of the
Liquidation Amount and all accumulated and unpaid Distributions to the date of
payment, to the extent that Sterling Capital has funds on hand available
therefor at such time, and (b) the amount of
 
                                       45
<PAGE>   48
 
assets of Sterling Capital remaining available for distribution to holders of
the Capital Securities on liquidation of Sterling Capital. The Company's
obligation to make a Guarantee Payment may be satisfied by direct payment of the
required amounts by the Company to the holders of the Capital Securities or by
causing Sterling Capital to pay such amounts to such holders.
 
     The Guarantee will be an irrevocable guarantee on a subordinated basis of
Sterling Capital's obligations under the Capital Securities, but will apply only
to the extent that Sterling Capital has funds sufficient to make such payments,
and is not a guarantee of collection.
 
     If the Company does not make payments on the Junior Subordinated Debentures
held by Sterling Capital, Sterling Capital will not be able to pay any amounts
payable in respect of the Capital Securities and will not have funds legally
available therefor. The Guarantee will rank subordinate and junior in right of
payment to all Senior Indebtedness of the Company. See "-- Status of the
Guarantee." The Guarantee does not limit the incurrence or issuance of other
secured or unsecured debt of the Company, including Senior Indebtedness, whether
under the Junior Subordinated Indenture, any other indenture that the Company
may enter into in the future or otherwise.
 
     The Company has, through the Guarantee, the Trust Agreement, the Junior
Subordinated Debentures and the Junior Subordinated Indenture, taken together,
fully, irrevocably and unconditionally guaranteed all Sterling Capital's
obligations under the Capital Securities on a subordinated basis. No single
document standing alone or operating in conjunction with fewer than all 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 Sterling Capital's obligations in respect of the
Capital Securities. See "Relationship Among the Capital Securities, the Junior
Subordinated Debentures and the Guarantee."
 
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 Indebtedness
of the Company in the same manner as the Junior Subordinated Debentures.
 
     The Guarantee will constitute a guarantee of payment and not of collection
(i.e., the guaranteed party may institute a legal proceeding directly against
the Guarantor to enforce its rights under the Guarantee without first
instituting a legal proceeding against any other person or entity). The
Guarantee will be held by the Guarantee Trustee for the benefit of the holders
of the Capital Securities. The Guarantee will not be discharged except by
payment of the Guarantee Payments in full to the extent not paid by Sterling
Capital or distribution to the holders of the Capital Securities of the Junior
Subordinated Debentures.
 
AMENDMENTS AND ASSIGNMENT
 
     Except with respect to any changes which do not materially adversely affect
the rights of holders of the Capital Securities (in which case no vote will be
required), the Guarantee may not be amended without the prior approval of the
holders of not less than a majority of the aggregate Liquidation Amount of the
outstanding Capital Securities. The manner of obtaining any such approval will
be as set forth under "Description of Capital Securities -- Voting Rights;
Amendment of Trust Agreement." All guarantees and agreements contained in the
Guarantee shall bind the successors, assigns, receivers, trustees and
representatives of the Company and shall inure to the benefit of the holders of
the Capital 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, or to
perform any non-payment obligation if such non-payment default remains
unremedied for 30 days. The holders of not less than a majority in aggregate
Liquidation Amount of the outstanding Capital Securities have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Guarantee Trustee in respect of the Guarantee or to direct the
exercise of any trust or power conferred upon the Guarantee Trustee under the
Guarantee.
 
                                       46
<PAGE>   49
 
     Any registered holder of Capital Securities may institute a legal
proceeding directly against the Company to enforce its rights under the
Guarantee without first instituting a legal proceeding against Sterling Capital,
the Guarantee Trustee or any other person or entity.
 
     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 the
occurrence of an event of 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 this provision, 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 the Capital Securities unless it is
offered reasonable indemnity against the costs, expenses and liabilities that
might be incurred thereby.
 
     For information concerning the relationship between Bankers Trust Company,
the Guarantee Trustee, and the Company, see "Description of Junior Subordinated
Debentures -- Information Concerning the Debenture Trustee."
 
TERMINATION OF THE GUARANTEE
 
     The Guarantee will terminate and be of no further force and effect upon
full payment of the Redemption Price of the Capital Securities, upon full
payment of the amounts payable with respect to the Capital Securities upon
liquidation of Sterling Capital or upon distribution of Junior Subordinated
Debentures to the holders of the Capital 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 Capital Securities must restore payment of any sums paid under the
Capital Securities or the Guarantee.
 
GOVERNING LAW
 
     The Guarantee will be governed by and construed in accordance with the laws
of the State of New York.
 
             RELATIONSHIP AMONG THE CAPITAL SECURITIES, THE JUNIOR
                   SUBORDINATED DEBENTURES AND THE GUARANTEE
 
FULL AND UNCONDITIONAL GUARANTEE
 
     Payments of Distributions and other amounts due on the Capital Securities
(to the extent Sterling Capital has funds available for such payment) are
irrevocably guaranteed, on a subordinated basis, by the Company as and to the
extent set forth under "Description of Guarantee." Taken together, the Company's
obligations under the Junior Subordinated Debentures, the Junior Subordinated
Indenture, the Trust Agreement and the Guarantee provide, in the aggregate, a
full, irrevocable and unconditional guarantee of payments of Distributions and
other amounts due on the Capital Securities. No single document standing alone
or operating in conjunction with fewer than all 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
Sterling Capital's obligations in respect of the Capital Securities. If and to
the extent that the Company does not make payments on the Junior Subordinated
Debentures, Sterling Capital will not have sufficient funds to pay Distributions
or other amounts due on the Capital Securities. The Guarantee does not cover
payment of amounts payable with respect to the Capital Securities when Sterling
Capital does not have sufficient funds to pay such amounts. In such event, the
remedy of a holder of the Capital Securities is to institute a legal proceeding
directly against the Company for enforcement of payment
 
                                       47
<PAGE>   50
 
of the Company's obligations under Junior Subordinated Debentures having a
principal amount equal to the Liquidation Amount of the Capital Securities held
by such holder.
 
     The obligations of the Company under the Junior Subordinated Debentures and
the Guarantee are subordinate and junior in right of payment to all Senior
Indebtedness.
 
SUFFICIENCY OF PAYMENTS
 
     As long as payments are made when due on the Junior Subordinated
Debentures, such payments will be sufficient to cover Distributions and other
payments distributable on the Capital Securities, primarily because (i) the
aggregate principal amount of the Junior Subordinated Debentures will be equal
to the sum of the aggregate stated Liquidation Amount of the Capital Securities
and Common Securities; (ii) the interest rate and interest and other payment
dates on the Junior Subordinated Debentures will match the Distribution rate,
Distribution Dates and other payment dates for the Capital Securities; (iii) the
Company will pay for any and all costs, expenses and liabilities of Sterling
Capital except Sterling Capital's obligations to holders of the Trust
Securities; and (iv) the Trust Agreement further provides that Sterling Capital
will not engage in any activity that is not consistent with the limited purposes
of Sterling Capital.
 
     Notwithstanding anything to the contrary in the Junior Subordinated
Indenture, the Company has the right to set-off any payment it is otherwise
required to make thereunder against and to the extent the Company has
theretofore made, or is concurrently on the date of such payment making, a
payment under the Guarantee.
 
ENFORCEMENT RIGHTS OF HOLDERS OF CAPITAL SECURITIES
 
     A holder of any Capital 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, Sterling Capital
or any other person or entity. See "Description of Guarantee."
 
     A default or event of default under any Senior Indebtedness of the Company
would not constitute a default or Event of Default in respect of the Capital
Securities. However, in the event of payment defaults under, or acceleration of,
Senior Indebtedness of the Company, the subordination provisions of the Junior
Subordinated Indenture provide that no payments may be made in respect of the
Junior Subordinated Debentures until such Senior Indebtedness has been paid in
full or any payment default thereunder has been cured or waived. See
"Description of Junior Subordinated Debentures -- Subordination."
 
LIMITED PURPOSE OF STERLING CAPITAL
 
     The Capital Securities represent preferred undivided beneficial interests
in the assets of Sterling Capital, and Sterling Capital exists for the sole
purpose of issuing its Capital Securities and Common Securities and investing
the proceeds thereof in Junior Subordinated Debentures. A principal difference
between the rights of a holder of a Capital Security and a holder of a Junior
Subordinated Debenture is that a holder of a Junior Subordinated Debenture is
entitled to receive from the Company payments on Junior Subordinated Debentures
held, while a holder of Capital Securities is entitled to receive Distributions
or other amounts distributable with respect to the Capital Securities from
Sterling Capital (or from the Company under the Guarantee) only if and to the
extent Sterling Capital has funds available for the payment of such
Distributions.
 
RIGHTS UPON DISSOLUTION
 
     Upon any voluntary or involuntary dissolution of Sterling Capital, other
than any such dissolution involving the distribution of the Junior Subordinated
Debentures, after satisfaction of liabilities to creditors of Sterling Capital
as required by applicable law, the holders of the Capital Securities will be
entitled to receive, out of assets held by Sterling Capital, the Liquidation
Distribution in cash. See "Description of Capital Securities -- Liquidation
Distribution Upon Dissolution." Upon any voluntary or involuntary liquidation or
bankruptcy of the Company, Sterling Capital, as registered holder of the Junior
Subordinated Debentures,
 
                                       48
<PAGE>   51
 
would be a subordinated creditor of the Company, subordinated and junior in
right of payment to all Senior Indebtedness as set forth in the Junior
Subordinated Indenture, but entitled to receive payment in full of all amounts
payable with respect to the Junior Subordinated Debentures before any
stockholders of the Company receive payments or distributions. Since the Company
is the guarantor under the Guarantee and has agreed under the Junior
Subordinated Indenture to pay for all costs, expenses and liabilities of
Sterling Capital (other than Sterling Capital's obligations to the holders of
the Trust Securities), the positions of a holder of the Capital Securities and a
holder of such Junior Subordinated Debentures relative to other creditors and to
stockholders 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
 
     Witherspoon, Kelley, Davenport & Toole, P.S., counsel to the Company ("Tax
Counsel"), has advised the Company that the following summary accurately
describes the material United States federal income tax consequences that may be
relevant to the purchase, ownership and disposition of the Capital Securities.
 
     This summary is based on the Internal Revenue Code of 1986, as amended (the
"Code"), Treasury regulations thereunder, and administrative and judicial
interpretations thereof, each as of the date of hereof, all of which are subject
to change, possibly on a retroactive basis. The authorities on which this
summary is based are subject to various interpretations, and the opinions of Tax
Counsel are not binding on the Internal Revenue Service (the "IRS") or the
courts; either of which could take a contrary position. Moreover, no rulings
have been or will be sought from the IRS with respect to the transactions
described herein. Accordingly, there can be no assurance that the IRS will not
challenge the opinions expressed herein or that a court would not sustain such a
challenge.
 
     Except as otherwise stated, this summary deals only with the Capital
Securities held as a capital asset by a holder who or which (i) purchased the
Capital Securities upon original issuance (an "Initial Holder") at their
original offering price and (ii) is a US Holder (as defined below). This summary
does not address all the tax consequences that may be relevant to a US Holder,
nor does it address the tax consequences, except as stated below, to holders
that are not US Holders ("Non-US Holders") or to holders that may be subject to
special tax treatment (such as banks, savings and loan institutions, real estate
investments trusts, regulated investment companies, insurance companies, brokers
and dealers in securities or currencies, other financial institutions,
tax-exempt organizations, persons holding the Capital Securities as a position
in a "straddle," as part of a "synthetic security," "hedging," "conversion" or
other integrated investment, persons having a functional currency other than the
U.S. Dollar and certain United States expatriates). Further, this summary does
not address (a) the income tax consequences to shareholders in, or partners or
beneficiaries of, a holder of the Capital Securities, (b) the United States
federal alternative minimum tax consequences of the purchase, ownership or
disposition of the Capital Securities, or (c) any state, local or foreign tax
consequences of the purchase, ownership and disposition of Capital Securities.
 
     A "US Holder" is a holder of the Capital Securities who or which is (i) a
citizen or individual resident (or is treated as a citizen or individual
resident) of the United States for income tax purposes, (ii) a corporation or
partnership created or organized (or treated as created or organized for income
tax purposes) in or under the laws of the United States or any political
subdivision thereof, (iii) an estate the income of which is includible in its
gross income for United States federal income tax purposes without regard to its
source, or (iv) a trust if (a) a court within the United States is able to
exercise primary supervision over the administration of the trust and (b) one or
more United States trustees have the authority to control all substantial
decisions of the trust.
 
     HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE TAX
CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE CAPITAL
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.
 
US HOLDERS
 
     Characterization of Sterling Capital. In connection with the issuance of
the Capital Securities, Tax Counsel will render its opinion generally to the
effect that, under then current law and based on the representations, facts and
assumptions set forth in this Prospectus, and assuming full compliance with the
terms of the Trust Agreement (and other relevant documents), and based on
certain assumptions and qualifications referenced in the opinion, Sterling
Capital will be characterized for United States federal income tax purposes as a
grantor trust and will not be characterized as an association taxable as a
corporation. Accordingly, for United States federal income tax purposes, each
holder of the Capital Securities generally will be considered the owner of an
undivided interest in the Junior Subordinated Debentures owned by Sterling
Capital, and each US Holder will be required to include all income or gain
recognized for United States federal income tax purposes with respect to its
allocable share of the Junior Subordinated Debentures on its own income tax
return.
 
     Characterization of the Junior Subordinated Debentures. The Company and
Sterling Capital will agree to treat the Junior Subordinated Debentures as
indebtedness for all United States federal income tax purposes. In connection
with the issuance of the Junior Subordinated Debentures, Tax Counsel will render
its opinion generally to the effect that, under then current law and based on
the representations, facts and assumptions set forth in this Prospectus, and
assuming full compliance with the terms of the Junior Subordinated Indenture
(and other relevant documents), and based on certain assumptions and
qualifications referenced in the opinion, the Junior Subordinated Debentures
will be characterized for United States federal income tax purposes as debt of
the Company.
 
     Interest Income and Original Issue Discount. Under the terms of the Junior
Subordinated Debentures, the Company has the ability to defer payments of
interest from time to time by extending the interest payment period not
exceeding 20 consecutive quarterly periods, but not beyond the maturity of the
Junior Subordinated Debentures. Recently issued Treasury regulations under
Section 1273 of the Code provide that debt instruments like the Junior
Subordinated Debentures will not be considered issued with original issue
discount ("OID") by reason of the Company's ability to defer payments of
interest if the likelihood of such deferral is "remote."
 
     The Company has concluded, and this discussion assumes, that, as of the
date of this Prospectus, the likelihood of deferring payments of interest under
the terms of the Junior Subordinated Debentures is "remote" within the meaning
of the applicable Treasury regulations, in part because exercising that option
would prevent the Company from declaring dividends on its capital stock and
would prevent the Company from making any payments with respect to debt
securities that rank pari passu with or junior to the Junior Subordinated
Debentures. Therefore, the Junior Subordinated Debentures should not be treated
as issued with OID by reason of the Company's deferral option. Rather, stated
interest on the Junior Subordinated Debentures will generally be taxable to a US
Holder as ordinary income when paid or accrued in accordance with that holder's
method of accounting for income tax purposes. It should be noted, however, that
these Treasury regulations have not yet been interpreted in any rulings or any
other published authorities of the IRS. Accordingly, it is possible that the IRS
could take a position contrary to the interpretation described herein.
 
     In the event the Company exercises its option to defer payments of
interest, the Junior Subordinated Debentures would be treated as redeemed and
reissued for OID purposes and the sum of the remaining interest payments (and
any de minimis OID) on the Junior Subordinated Debentures would thereafter be
treated as OID, which would accrue, and be includible in a US Holder's taxable
income, on an economic accrual basis (regardless of the US Holder's method of
accounting for income tax purposes) over the remaining term of the Junior
Subordinated Debentures (including any period of interest deferral), without
regard to the timing of payments under the Junior Subordinated Debentures.
(Subsequent distributions of interest on the Junior Subordinated Debentures
generally would not be taxable.) The amount of OID that would accrue in any
period would generally equal the amount of interest that accrued on the Junior
 
                                       50
<PAGE>   53
 
Subordinated Debentures in that period at the stated interest rate.
Consequently, during any period of interest deferral, US Holders will include
OID in gross income in advance of the receipt of cash, and a US Holder which
disposes of a Capital Security prior to the record date for payment of
distributions on the Junior Subordinated Debentures following that period will
be subject to income tax on OID accrued through the date of disposition (and not
previously included in income), but will not receive cash from Sterling Capital
with respect to the OID.
 
     If the possibility of the Company's exercise of its option to defer payment
of interest is not treated as remote, the Junior Subordinated Debentures would
be treated as initially issued with OID in an amount equal to the aggregate
stated interest (plus any de minimis OID) over the term of the Junior
Subordinated Debentures. That OID would generally be includible in a US Holder's
taxable income, over the term of the Junior Subordinated Debentures, on an
economic accrual basis.
 
     Characterization of Income. Because the income underlying the Capital
Securities will not be characterized as dividends for income tax purposes,
corporate holders of the Capital Securities will not be entitled to a dividends
received deduction for any income recognized with respect to the Capital
Securities.
 
     Market Discount and Bond Premium. Holders of the Capital Securities other
than Initial Holders may be considered to have acquired their undivided
interests in the Junior Subordinated Debentures with market discount or
acquisition premium (as each phrase is defined for United States federal income
tax purposes).
 
     Receipt of Junior Subordinated Debentures or Cash Upon Liquidation of
Sterling Capital. Under certain circumstances described herein (See "Description
of Capital Securities -- Liquidation Distribution Upon Dissolution"), Sterling
Capital may distribute the Junior Subordinated Debentures to holders in exchange
for the Capital Securities and in liquidation of Sterling Capital. Except as
discussed below, such a distribution would not be a taxable event for United
States federal income tax purposes, and each US Holder would have an aggregate
adjusted basis in its Junior Subordinated Debentures for United States federal
income tax purposes equal to such holder's aggregate adjusted basis in its
Capital Securities. For United States federal income tax purposes, a US Holder's
holding period in the Junior Subordinated Debentures received in such a
liquidation of Sterling Capital would include the period during which Capital
Securities were held by the holder. If, however, the relevant event is a Tax
Event which results in Sterling Capital being treated as an association taxable
as a corporation, the distribution would likely constitute a taxable event to US
Holders of the Capital Securities for United States federal income tax purposes.
 
     Under certain circumstances described herein (see "Description of Capital
Securities"), the Junior Subordinated Debentures may be redeemed for cash and
the proceeds of such redemption distributed to holders in redemption of their
Capital Securities. Such a redemption would be taxable for United States federal
income tax purposes, and a US Holder would recognize gain or loss as if it had
sold the Capital Securities for cash. See "-- Sales of Capital Securities"
below.
 
     Sales of Capital Securities. A US Holder that sells Capital Securities will
recognize gain or loss equal to the difference between its adjusted basis in the
Capital Securities and the amount realized on the sale of such Capital
Securities. A US Holder's adjusted basis in the Capital Securities generally
will be its initial purchase price, increased by OID previously included (or
currently includible) in such holder's gross income to the date of disposition,
and decreased by payments received on the Capital Securities (other than any
interest received with respect to the period prior to the effective date of the
Company's first exercise of its option to defer payment of interest). Any such
gain or loss generally will be capital gain or loss, and generally will be a
long-term capital gain or loss if the Capital Securities have been held for more
than one year prior to the date of disposition.
 
     A holder who disposes of his Capital Securities between record dates for
payments of distributions thereon will be required to include accrued but unpaid
interest (or OID) on the Junior Subordinated Debentures through the date of
disposition in its taxable income for United States federal income tax purposes
(notwithstanding that the holder may receive a separate payment from the
purchaser with respect to accrued interest), and to deduct that amount from the
sale proceeds received (including the separate payment, if any, with respect to
accrued interest) for the Capital Securities (or as to OID only, to add such
amount to such
 
                                       51
<PAGE>   54
 
holder's adjusted tax basis in its Capital Securities). To the extent the
selling price is less than the holder's adjusted tax basis (which will include
accrued but unpaid OID, if any), 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.
 
   
     Proposed Tax Law Changes. On February 6, 1997, President Clinton released
his budget proposals for fiscal year 1998. One of the tax proposals therein (the
"Tax Proposal") would generally deny corporate issuers a deduction for interest
on certain debt obligations that have a maximum term in excess of 15 years and
are not shown as indebtedness on the separate balance sheet of the issuer or,
where the instrument is issued to a related party (other than a corporation),
where the holder or some other related party issues a related instrument that is
not shown as indebtedness on the issuer's consolidated balance sheet. As
currently drafted, the Tax Proposal would be effective generally for instruments
issued on or after the date of first Congressional committee action. Although it
is not clear from the President's proposals as to what constitutes Congressional
"committee action" with respect to the Tax Proposal, it appears that, as
drafted, the Tax Proposal would not apply retroactively to the Junior
Subordinated Debentures. However, if the Tax Proposal (or similar legislation)
is enacted with retroactive effect with respect to the Junior Subordinated
Debentures, the Company may not be entitled to an interest deduction with
respect to the Junior Subordinated Debentures. There can be no assurances that
the Tax Proposal, if enacted, will not apply retroactively to the Junior
Subordinated Debentures or 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 Junior Subordinated Debentures. Accordingly, there can
be no assurance that a Tax Event will not occur. See "Description of Capital
Securities -- Redemption."
    
 
NON-US HOLDERS
 
     The following discussion applies to a Non-US Holder.
 
     Payments to a holder of a Capital Security which is a Non-US Holder will
generally not be subject to withholding of income tax, provided that (a) the
beneficial owner of the Capital Security does not (directly or indirectly,
actually or constructively) own 10% or more of the total combined voting power
of all classes of stock of the Company entitled to vote, (b) the beneficial
owner of the Capital Security is not a controlled foreign corporation that is
related to the Company through stock ownership, and (c) either (i) the
beneficial owner of the Capital Securities certifies to Sterling Capital or its
agent, under penalties of perjury, that it is a Non-US Holder and provides its
name and address, or (ii) a securities clearing organization, bank or other
financial institution that holds customers' securities in the ordinary course of
its trade or business (a "Financial Institution"), and holds the Capital
Security in such capacity, certifies to Sterling Capital or its agent, under
penalties of perjury, that such a statement has been received from the
beneficial owner by it or by another Financial Institution between it and the
beneficial owner in the chain of ownership, and furnishes Sterling Capital or
its agent with a copy thereof.
 
   
     As discussed above, changes in legislation affecting the income tax
consequences of the Junior Subordinated Debentures are possible, and could
adversely affect the ability of the Company to deduct the interest payable on
the Junior Subordinated Debentures. See "-- US Holders -- Proposed Tax Law
Changes." Moreover, any such legislation could adversely affect Non-US Holders
by characterizing income derived from the Junior Subordinated Debentures as
dividends, generally subject to a 30% income tax (on a withholding basis) when
paid to a Non-US Holder, rather than as interest which, as discussed above, is
generally exempt from income tax in the hands of a Non-US Holder.
    
 
     A Non-US Holder of a Capital Security will generally not be subject to
withholding of income tax on any gain realized upon the sale or other
disposition of a Capital Security.
 
     A Non-US Holder which holds the Capital Securities in connection with the
active conduct of a United States trade or business will be subject to income
tax on all income and gains recognized with respect to its proportionate share
of the Junior Subordinated Debentures.
 
                                       52
<PAGE>   55
 
INFORMATION REPORTING
 
   
     In general, information reporting requirements will apply to payments made
on, and proceeds from the sale of, the Capital Securities held by a
non-corporate US Holder within the United States. In addition, payments made on,
and payments of the proceeds from the sale of, the Capital Securities to or
through the United States office of a broker are subject to information
reporting unless the holder thereof certifies as to its Non-United States status
or otherwise establishes an exemption from information reporting and backup
withholding. See "-- Backup Withholding." Taxable income on the Capital
Securities for a calendar year should be reported to US Holders on the
applicable forms by the following January 31st.
    
 
BACKUP WITHHOLDING
 
     Payments made on, and proceeds from the sale of, the Capital Securities may
be subject to a "backup" withholding tax of 31% unless the holder complies with
certain identification or exemption requirements. Any amounts so withheld will
be allowed as a credit against the holder's income tax liability, or refunded,
provided the required information is provided to the IRS.
 
     THE PRECEDING DISCUSSION IS ONLY A SUMMARY AND DOES NOT ADDRESS THE
CONSEQUENCES TO A PARTICULAR HOLDER OF THE PURCHASE, OWNERSHIP AND DISPOSITION
OF THE CAPITAL SECURITIES. POTENTIAL HOLDERS OF THE CAPITAL SECURITIES ARE URGED
TO CONTACT THEIR OWN TAX ADVISORS TO DETERMINE THEIR PARTICULAR TAX
CONSEQUENCES.
 
                          CERTAIN ERISA CONSIDERATIONS
 
     The Company and certain affiliates of the Company may each be considered a
"party in interest" within the meaning of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA") or a "disqualified person" within the
meaning of Section 4975 of the Internal Revenue Code of 1986, as amended (the
"Code") with respect to many employee benefit plans ("Plans") that are subject
to ERISA. The purchase of the Capital Securities by a Plan that is subject to
the fiduciary responsibility provisions of ERISA or the prohibited transaction
provisions of Section 4975(e)(1) of the Code and with respect to which the
Company, or any affiliate of the Company is a service provider (or otherwise is
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 the
Capital Securities are acquired pursuant to and in accordance with an applicable
exemption. Any pension or other employee benefit plan proposing to acquire any
Capital Securities should consult with its counsel.

     The Underwriting Agreement provides that the Underwriters' obligations are
subject to conditions precedent and that the Underwriters are committed to
purchase all of the Capital Securities offered hereby if the Underwriters
purchase any Capital Securities.
 
     The Underwriters have advised the Company and Sterling Capital that they
propose to offer the Capital Securities to the public at the Price to Public set
forth on the cover page of this Prospectus and to selected dealers at such price
less a concession not in excess of $     per Capital Security. The Underwriters
may allow and such dealers may reallow a discount not in excess of $     per
Capital Security to certain other brokers and dealers. After the offering, the
Price to Public, concession, discount, and other selling terms may be changed by
the Underwriters.
 
   
     In connection with the offering of the Capital Securities, the Underwriters
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 Capital Securities. Such transactions may include over-allotment
transactions in which the Underwriters create a short position for their own
account by selling more Capital Securities than they are committed to purchase
from Sterling Capital. In such a case, to cover all or part of the short
position, the Underwriters may purchase Capital Securities in the open market
following completion of the initial offering of the Capital Securities. The
Underwriters also may engage in stabilizing transactions in which they bid for,
and purchase, shares of the Capital 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 Capital Securities. Any of the foregoing
transactions may result in the maintenance of a price for the Capital Securities
at a level above that which might otherwise prevail in the open market. Neither
the Company nor any of the Underwriters makes any representation or prediction
as to the direction or magnitude of any effect that the transactions described
above may have on the price of the Capital Securities. The Underwriters are not
required to engage in any of the foregoing transactions and, if commenced, such
transactions may be discontinued at any time without notice.
    
 
   
     In view of the fact that all of the proceeds from the sale of the Capital
Securities will be used to purchase the Junior Subordinated Debentures, the
Underwriting Agreement provides that the Company will pay the Underwriters as
compensation for arranging the investment therein of such proceeds, $     per
Capital Security.
    
 
     Each of the Company and Sterling Capital has agreed to indemnify the
Underwriters and their controlling persons against certain liabilities,
including liabilities under the Securities Act of 1933, as amended, or to
contribute to payments the Underwriters may be required to make in respect
thereof.
 
     The Underwriters have advised Sterling Capital that they do not intend to
confirm any sales of Capital Securities to any discretionary accounts. In
connection with the offer and sale of the Capital Securities, the Underwriters
will comply with Rule 2810 under the NASD Conduct Rules.
 
   
     From time to time, the Underwriters have provided, and expect to provide in
the future, investment banking services to the Company for which the
Underwriters have received, and will receive, customary fees and commissions.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Washington law permits and the Restated Articles of Incorporation and the
Bylaws of the Registrant provide that to the fullest extent allowed by
applicable laws existing from time to time, any person may, and directors and
officers shall, be indemnified or reimbursed by the Registrant for reasonable
expenses (including attorneys' fees) actually incurred in connection with any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative to which he or she shall be made a
party or threatened to be made a party by reason of his or her being or having
been a director, officer, employee or agent of the Registrant or of any firm,
corporation, employee benefit plan or other organization which he or she served
in any such capacity at the request of the Registrant; provided, however, that
no person shall be so indemnified or reimbursed (1) in relation to any matter in
such action, suit or proceeding as to which he or she shall finally be adjudged
to have been guilty or liable for gross negligence, willful misconduct or
criminal acts in the performance of his or her duties to the Registrant; or (2)
in relation to any matter in such action, suit or proceeding which has been made
the subject of a compromise settlement except with the approval of (a) a court
of competent jurisdiction, (b) the holders of record of a majority of the
outstanding shares of the Registrant or (c) the Board of Directors, acting by
vote of a majority of directors not parties to the same or substantially the
same action, suit or proceeding, whether or not such majority constitutes a
quorum. The foregoing right of indemnification or reimbursement shall not be
exclusive of other rights to which such person, his or her heirs, executors or
administrators may be entitled as a matter of law. Those persons indemnified
hereunder shall be deemed to include the heirs, legal representatives, executors
and administrators of such person.
 
     Expenses (including attorneys' fees) incurred in defending a civil or
criminal action, suit or proceeding shall be paid by the Registrant in advance
of the final disposition of such action, suit or proceeding. The director,
officer, employee or agent must repay such amount, however, if it shall
ultimately be determined that he or she is not entitled to be indemnified by the
Registrant.
 
     The Registrant's Restated Articles of Incorporation also provide that a
director of the Registrant shall not be personally liable to the Registrant or
its shareholders for monetary damages for conduct as a director, except for
liability of the director for (i) acts or omissions that involve intentional
misconduct or a knowing violation of law by the director, (ii) conduct which
violates RCW 23B.08.310 of the Washington Business Corporation Act pertaining to
unpermitted distributions to shareholders or loans to directors or (iii) any
transaction from which the director will personally receive a benefit in money,
property or services to which
 
                                      II-1
<PAGE>   60
 
the director is not legally entitled. If the Washington Business Corporation Act
is amended to authorize corporate action further eliminating or limiting the
personal liability of directors, then the liability of a director of the
Registrant shall be eliminated or limited to the fullest extent permitted by the
Washington Business Corporation Act, as so amended. Any repeal or modification
of the foregoing paragraph by the shareholders of the Registrant shall not
adversely affect any right or protection of a director of the Registrant
existing at the time of such repeal or modification.
 
ITEM 16. EXHIBITS
 
     The exhibits listed on the Exhibit Index on page II-5 of this Registration
Statement are filed herewith, incorporated by reference or will be filed by
amendment.
 
ITEM 17. UNDERTAKINGS
 
     Each of the undersigned Registrants hereby undertakes:
 
          (a) The undersigned Registrant hereby undertakes that, for the
     purposes of determining any liability under the Securities Act of 1933,
     each filing of the Registrant's annual report pursuant to section 13 (a) or
     section 15(d) of the Securities Exchange Act of 1934 (and, where
     applicable, each filing of an employee benefit plan's annual report
     pursuant to section 15(d) of the Securities Exchange Act of 1934) that is
     incorporated by reference in the Registration Statement 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.
 
          (b) Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 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 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 issuer 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 Act and will be governed by the final
     adjudication of such issue.
 
        (c) The undersigned registrant hereby undertakes that:
 
             (1) For the purposes of determining any liability under the
        Securities Act of 1933, the information omitted from the form of
        prospectus filed as part of this Registration Statement in reliance upon
        Rule 430A and contained in a form of prospectus filed by the Registrant
        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.
 
             (2) For the purpose of determining any liability under the
        Securities Act of 1933, each posteffective 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.

         of Counsel (as defined in the relevant Trust Agreement) experienced in

         States Federal income tax purposes, or (iii) such Issuer Trust is, or

         other governmental charges.

                Upon any application or request by the Company to the Trustee to
         take any action under any provision of this Indenture, the Company
         shall furnish to the Trustee an Officers' Certificate stating that all
         conditions precedent (including covenants compliance with which
         constitutes a condition precedent), if any, provided for in this
         Indenture relating to the proposed action have been complied with and
         an Opinion of Counsel stating that, in the opinion of such counsel, all
         such conditions precedent (including covenants compliance with which
         constitutes a condition precedent), if any, have been complied with,
         except that in the case of any such application or request as to which
         the furnishing of such documents is specifically required by any
         provision of this Indenture relating to such particular application or
         request, no additional certificate or opinion need be furnished.

         certificates provided pursuant to Section 10.4) shall include:

                     (1) a statement by each individual signing such certificate
                or opinion that such individual has read such covenant or
                condition and the definitions herein relating thereto;

                     (2) a brief statement as to the nature and scope of the
                examination or investigation upon which the statements or
                opinions of such individual contained in such certificate or
                opinion are based;

                     (3)  a statement that, in the opinion of such
                individual, he or she has made such examination or
                investigation as is necessary to enable him or her to
<PAGE>   20

                                       - 14 -


                express an informed opinion as to whether or not such
                covenant or condition has been complied with; and

                     (4) a statement as to whether, in the opinion of such
                individual, such condition or covenant has been complied with.

                SECTION 1.3.   Forms of Documents Delivered to Trustee.

                In any case where several matters are required to be certified
         by, or covered by an opinion of, any specified Person, it is not
         necessary that all such matters be certified by, or covered by the
         opinion of, only one such Person, or that they be so certified or
         covered by only one document, but one such Person may certify or give
         an opinion with respect to some matters and one or more other such
         Persons as to other matters, and any such Person may certify or give an
         opinion as to such matters in one or several documents.

                Any certificate or opinion of an officer of the Company may be
         based, insofar as it relates to legal matters, upon a certificate or
         opinion of, or representations by, counsel, unless such officer knows,
         or in the exercise of reasonable care should know, that the certificate
         or opinion or representations with respect to matters upon which his or
         her certificate or opinion is based are erroneous. Any such certificate
         or Opinion of Counsel may be based, insofar as it relates to factual
         matters, upon a certificate or opinion of, or representations by, an
         officer or officers of the Company stating that the information with
         respect to such factual matters is in the possession of the Company,
         unless such counsel knows, or in the exercise of reasonable care should
         know, that the certificate or opinion or representations with respect
         to such matters are erroneous.

                Where any Person is required to make, give or execute two or
         more applications, requests, consents, certificates, statements,
         opinions, or other instruments under this Indenture, they may, but need
         not, be consolidated and form one instrument.

                SECTION 1.4.   Acts of Holders.

                (a) Any request, demand, authorization, direction, notice,
         consent, waiver or other action provided by this Indenture to be given
         to or taken by Holders may be embodied in and evidenced by one or more
         instruments of substantially similar tenor signed by such Holders in
         person or by an agent duly appointed in writing; and, except as herein
         otherwise expressly provided, such action shall become effective when
         such instrument or instruments is or are delivered to the Trustee, and,
         where it is hereby expressly required, to the Company. Such instrument
         or instruments (and the action embodied therein and evidenced thereby)
         are herein
<PAGE>   21

                                       - 15 -


         sometimes referred to as the "Act" of the Holders 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 Indenture and (subject to Section 6.1) conclusive in
         favor of the Trustee and the Company, if made in the manner provided in
         this Section.

                (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 the certificate of any 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 or her the execution thereof. Where such execution is by a Person
         acting in other than his or her individual capacity, such certificate
         or affidavit shall also constitute sufficient proof of his or her
         authority.

                (c) The fact and date of the execution by any Person of any such
         instrument or writing, or the authority of the Person executing the
         same, may also be provided in any other manner that the Trustee deems
         sufficient and in accordance with such reasonable rules as the Trustee
         may determine.

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

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

                (f) The Company may set any day as a record date for the purpose
         of determining the Holders of Outstanding Securities of any series
         entitled to give, make or take any request, demand, authorization,
         direction, notice, consent, waiver or other action provided or
         permitted by this Indenture to be given, made or taken by Holders of
         Securities of such series, provided that the Company may not set a
         record date for, and the provisions of this paragraph shall not apply
         with respect to, the giving or making of any notice, declaration,
         request or direction referred to in the next succeeding paragraph. If
         any record date is set pursuant to this paragraph, the Holders of
         Outstanding Securities of the relevant series on such record date, and
         no other Holders, shall be entitled to take the relevant action,
         whether or not such Holders remain Holders after such record date,
         provided that no such action shall be effective hereunder unless taken
         on or prior to the applicable Expiration Date (as defined below) by
         Holders of
<PAGE>   22

                                       - 16 -


         the requisite principal amount of Outstanding Securities of such series
         on such record date. Nothing in this paragraph shall be construed to
         prevent the Company from setting a new record date for any action for
         which a record date has previously been set pursuant to this paragraph
         (whereupon the record date previously set shall automatically and with
         no action by any Person be cancelled and of no effect), and nothing in
         this paragraph shall be construed to render ineffective any action
         taken by Holders of the requisite principal amount of Outstanding
         Securities of the relevant series on the date such action is taken.
         Promptly after any record date is set pursuant to this paragraph, the
         Company, at its own expense, shall cause notice of such record date,
         the proposed action by Holders and the applicable Expiration Date to be
         given to the Trustee in writing and to each Holder of Securities of the
         relevant series in the manner set forth in Section 1.6.

                The Trustee may set any day as a record date for the purpose of
         determining the Holders of Outstanding Securities of any series
         entitled to join in the giving or making of (i) any Notice of Default,
         (ii) any declaration of acceleration referred to in Section 5.2, (iii)
         any request to institute proceedings referred to in Section 5.7(2), or
         (iv) any direction referred to in Section 5.12, in each case with
         respect to Securities of such series. If any record date is set
         pursuant to this paragraph, the Holders of Outstanding Securities of
         such series on such record date, and no other Holders, shall be
         entitled to join in such notice, declaration, request or direction,
         whether or not such Holders remain Holders after such record date,
         provided that no such action shall be effective hereunder unless taken
         on or prior to the applicable Expiration Date by Holders of the
         requisite principal amount of Outstanding Securities of such series on
         such record date. Nothing in this paragraph shall be construed to
         prevent the Trustee from setting a new record date for any action for
         which a record date has previously been set pursuant to this paragraph
         (whereupon the record date previously set shall automatically and with
         no action by any Person be cancelled and of no effect) and nothing in
         this paragraph shall be construed to render ineffective any action
         taken by Holders of the requisite principal amount of Outstanding
         Securities of the relevant series on the date such action is taken.
         Promptly after any record date is set pursuant to this paragraph, the
         Trustee, at the Company's expense, shall cause notice of such record
         date, the proposed action by Holders and the applicable Expiration Date
         to be given to the Company in writing and to each Holder of Securities
         of the relevant series in the manner set forth in Section 1.6.

                With respect to any record date set pursuant to this Section,
         the party hereto that sets such record date may designate any day as
         the "Expiration Date" and from time to time may change the Expiration
         Date to any earlier or later day, provided that no
<PAGE>   23

                                       - 17 -


         such change shall be effective unless notice of the proposed new
         Expiration Date is given to the other party hereto in writing, and to
         each Holder of Securities of the relevant series in the manner set
         forth in Section 1.6 on or prior to the existing Expiration Date. If an
         Expiration Date is not designated with respect to any record date set
         pursuant to this Section, the party hereto that set such record date
         shall be deemed to have initially designated the 180th day after such
         record date as the Expiration Date with respect thereto, subject to its
         right to change the Expiration Date as provided in this paragraph.
         Notwithstanding the foregoing, no Expiration Date shall be later than
         the 180th day after the applicable record date.

                (g) Without limiting the foregoing, a Holder entitled hereunder
         to take any action hereunder with regard to any particular Security may
         do so with regard to all or any part of the principal amount of such
         Security or by one or more duly appointed agents each of which may do
         so pursuant to such appointment with regard to all or any part of such
         principal amount.

                SECTION 1.5.   Notices, Etc. to Trustee and Company.

                Any request, demand, authorization, direction, notice, consent,
         waiver or Act of Holders or other document provided or permitted by
         this Indenture to be made upon, given or furnished to, or filed with,

                     (1) the Trustee by any Holder, any holder of Capital
                Securities or the Company shall be sufficient for every purpose
                hereunder if made, given, furnished or filed in writing to or
                with the Trustee at its Corporate Trust Office, or

                     (2) the Company by the Trustee, any Holder or any holder of
                Capital Securities shall be sufficient for every purpose (except
                as otherwise provided in Section 5.1) hereunder if in writing
                and mailed, first class, postage prepaid, to the Company
                addressed to it at the address of its principal office specified
                in the first paragraph of this instrument or at any other
                address previously furnished in writing to the Trustee by the
                Company.

                SECTION 1.6.   Notice to Holders; Waiver.

                Where this Indenture provides for notice to Holders of any
         event, such notice shall be sufficiently given (unless otherwise herein
         expressly provided) if in writing and mailed, first class postage
         prepaid, to each Holder affected by such event, at the address of such
         Holder as it appears in the Securities Register, not later than the
         latest date, and not earlier than the earliest
<PAGE>   24

                                       - 18 -


         date, prescribed for the giving of such notice. If, by reason of the
         suspension of or irregularities in regular mail services or for any
         other reason, it shall be impossible or impracticable to mail notice of
         any event to Holders when said notice is required to be given pursuant
         to any provision of this Indenture or of the relevant Securities, then
         any manner of giving such notice as shall be satisfactory to the
         Trustee shall be deemed to be a sufficient giving of such notice. In
         any case where notice to Holders is given by mail, neither the failure
         to mail such notice, nor any defect in any notice so mailed, to any
         particular Holder shall affect the sufficiency of such notice with
         respect to other Holders. Where this Indenture provides for notice in
         any manner, such notice may be waived in writing by the Person entitled
         to receive such notice, either before or after the event, and such
         waiver shall be the equivalent of such notice. Waivers of notice by
         Holders shall be filed with the Trustee, but such filing shall not be a
         condition precedent to the validity of any action taken in reliance
         upon such waiver.

                SECTION 1.7.   Conflict with Trust Indenture Act.

                If any provision hereof limits, qualifies or conflicts with a
         provision of the Trust Indenture Act that is required under such Act to
         be a part of and govern this Indenture, the provision of the Trust
         Indenture Act shall control. If any provision of this Indenture
         modifies or excludes any provision of the Trust Indenture Act that may
         be so modified or excluded, the latter provision shall be deemed to
         apply to this Indenture as so modified or to be excluded, as the case
         may be.

                SECTION 1.8.   Effect of Headings and Table of Contents.

                The Article and Section headings herein and the Table of
         Contents are for convenience only and shall not affect the construction
         hereof.

                SECTION 1.9.   Successors and Assigns.

                All covenants and agreements in this Indenture by the Company
         shall bind its successors and assigns, whether so expressed or not.

                SECTION 1.10.  Separability Clause.

                If any provision in this Indenture or in the Securities shall be
         invalid, illegal or unenforceable, the validity, legality and
         enforceability of the remaining provisions shall not in any way be
         affected or impaired thereby.

         next succeeding Business Day (and no interest shall accrue in respect

         such payment shall be made on the immediately preceding Business Day
         (in each case with the same force and effect as if made on the Interest
         Payment Date or Redemption Date or at the Stated Maturity).

         passu with or junior to such stock). Prior to the termination of any
         such Extension Period, the Company may further defer the payment of
         interest, provided that no Extension Period shall exceed _______

         termination of any such Extension Period and upon the payment of all
         accrued and unpaid interest and any Additional Interest then due on any
         Interest Payment Date, the Company may elect to begin a new Extension
         Period, subject to the above conditions. No interest shall be due and
         payable during an Extension Period, except at the end thereof, but each

         extent that the payment of such interest shall be legally enforceable)
         at the rate of __% per annum, compounded [monthly] [quarterly]

         this Security, from the date on which such amounts would otherwise have
         been due and payable until paid or made available for payment. The

         of its election to begin any Extension Period at least one Business Day

         such Issuer Trust is required to give notice to holders of such Capital
         Securities of the record date or the date such Distributions are
         payable, but in any event not less than one Business Day prior to such
         record date.]

                Payment of the principal of (and premium, if any) and interest
         on this Security will be made at the office or agency of the Company
         maintained for that purpose in the United States, in such coin or
         currency of the United States of America as at the time of payment is
         legal tender for payment of public and private debts [if applicable,
         insert--; provided, however that at the option of the Company payment
         of interest may be made (i) by check mailed to the address of the
         Person entitled thereto as such address shall appear in the Securities
         Register, or (ii) if to a Holder of $1,000,000 or more in aggregate
         principal amount of this Security, by wire transfer in immediately
         available funds upon written request to the Trustee not later than 15
         calendar days prior to the date on which the interest is payable].

                The indebtedness evidenced by this Security is, to the extent
         provided in the Indenture, subordinate and subject in right of payments
         to the prior payment in full of all Senior Indebtedness, and this
         Security is issued subject to the provisions of the Indenture with
         respect thereto. Each Holder of this Security, by accepting the same,
         (a) agrees to and shall be bound by such provisions, (b) authorizes and
         directs the Trustee on his or her behalf to take such actions as may be
         necessary or appropriate to 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,
         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.

                Reference is hereby made to the further provisions of this
         Security set forth on the reverse hereof, which further provisions
         shall for all purposes have the same effect as if set forth at this
         place.

         executed by the Trustee referred to on the reverse hereof by manual
         signature, this Security shall not be entitled to any benefit under the
         Indenture or be valid or obligatory for any purpose.

         Chairman of the Board, its Vice Chairman of the Board, its President or
         one of its Vice Presidents, under its corporate seal reproduced or
         impressed thereon and attested by its Secretary or one of its Assistant
         Secretaries. The signature of any of these officers on the Securities
         may be manual or facsimile.

                Securities bearing the manual or facsimile signatures of
         individuals who were at any time the proper officers of the Company
         shall bind the Company, notwithstanding that such individuals or any of
         them have ceased to hold such offices prior to the authentication and
         delivery of such Securities or did not hold such offices at the date of
         such Securities. At any time and

                                       - 34 -


         from time to time after the execution and delivery of this Indenture,
         the Company may deliver Securities of any series executed by the
         Company to the Trustee for authentication, together with a Company
         Order for the authentication and delivery of such Securities, and the
         Trustee in accordance with the Company Order shall authenticate and
         deliver such Securities. If the form or terms of the Securities of the
         series have been established by or pursuant to one or more Board
         Resolutions as permitted by Sections 2.1 and 3.1, in authenticating
         such Securities, and accepting the additional responsibilities under
         this Indenture in relation to such Securities, the Trustee shall be
         entitled to receive, and (subject to Section 6.1) shall be fully
         protected in relying upon, an Opinion of Counsel stating,

                     (1) if the form of such Securities has been established by
                or pursuant to Board Resolution as permitted by Section 2.1,
                that such form has been established in conformity with the
                provisions of this Indenture;

                     (2) if the terms of such Securities have been established
                by or pursuant to Board Resolution as permitted by Section 3.1,
                that such terms have been established in conformity with the
                provisions of this Indenture; and

                     (3) that such Securities, when authenticated and delivered
                by the Trustee and issued by the Company in the manner and
                subject to any conditions specified in such Opinion of Counsel,
                will constitute valid and legally binding obligations of the
                Company enforceable in accordance with their terms, subject to
                bankruptcy, insolvency, fraudulent transfer, reorganization,
                moratorium and similar laws of general applicability relating to
                or affecting creditors' rights and to general equity principles.

         If such form or terms have been so established, the Trustee shall not
         be required to authenticate such Securities if the issue of such
         Securities pursuant to this Indenture will affect the Trustee's own
         rights, duties or immunities under the Securities and this Indenture or
         otherwise in a manner that is not reasonably acceptable to the Trustee.

                Notwithstanding the provisions of Section 3.1 and the preceding
         paragraph, if all Securities of a series are not to be originally
         issued at one time, it shall not be necessary to deliver the Officers'
         Certificate otherwise required pursuant to Section 3.1 or the Company
         Order and Opinion of Counsel otherwise required pursuant to such
         preceding paragraph at or prior to the authentication of each Security
         of such series if such documents are delivered at or prior to the
         authentication upon original issuance of the first Security of such
         series to be issued.
<PAGE>   41

                                       - 35 -



                Each Security shall be dated the date of its authentication.

                No Security shall be entitled to any benefit under this
         Indenture or be valid or obligatory for any purpose, unless there
         appears on such Security a certificate of authentication substantially
         in the form provided for herein executed by the Trustee by the manual
         signature of one of its authorized officers, and such certificate upon
         any Security shall be conclusive evidence, and the only evidence, that
         such security has been duly authenticated and delivered hereunder.
         Notwithstanding the foregoing, if any Security shall have been
         authenticated and delivered hereunder but never issued and sold by the
         Company, and the Company shall deliver such Security to the Trustee for
         cancellation as provided in Section 3.10, for all purposes of this
         Indenture such Security shall be deemed never to have been
         authenticated and delivered hereunder and shall never be entitled to
         the benefits of this Indenture.

                SECTION 3.4.   Temporary Securities.

                Pending the preparation of definitive Securities of any series,
         the Company may execute, and upon receipt of a Company Order the
         Trustee shall authenticate and deliver, temporary Securities that are
         printed, lithographed, typewritten, mimeographed or otherwise produced,
         in any denomination, substantially of the tenor of the definitive
         Securities of such series in lieu of which they are issued and with
         such appropriate insertions, omissions, substitutions and other
         variations as the officers executing such Securities may determine, as
         evidenced by their execution of such Securities.

                If temporary Securities of any series are issued, the Company
         will cause definitive Securities of such series to be prepared without
         unreasonable delay. After the preparation of definitive Securities, the
         temporary Securities shall be exchangeable for definitive Securities
         upon surrender of the temporary Securities at the office or agency of
         the Company designated for that purpose without charge to the Holder.
         Upon surrender for cancellation of any one or more temporary
         Securities, the Company shall execute and the Trustee shall
         authenticate and deliver in exchange therefor one or more definitive
         securities of the same series, of any authorized denominations having
         the same Original Issue Date and Stated Maturity and having the same
         terms as such temporary Securities. Until so exchanged, the temporary
         Securities of any series shall in all respects be entitled to the same
         benefits under this Indenture as definitive Securities of such series.

                SECTION 3.5.   Global Securities.

                (a) Each Global Security issued under this Indenture shall be
         registered in the name of the Depositary designated by the Company for
         such Global Security or a nominee thereof and delivered to such
         Depositary or a nominee thereof or custodian therefor, and each such
         Global Security shall constitute a single Security for all purposes of
         this Indenture.

                (b) Notwithstanding any other provision in this Indenture, no
         Global Security may be exchanged in whole or in part for Securities
         registered, and no transfer of a Global Security in whole or in part
         may be registered, in the name of any Person other than the Depositary
         for such Global Security or a nominee thereof unless (i) such
         Depositary advises the Trustee in writing that such Depositary is no
         longer willing or able to properly discharge its responsibilities as
         Depositary with respect to such Global Security, and the Company is
         unable to locate a qualified successor, (ii) the Company executes and
         delivers to the Trustee a Company Order stating that the Company elects
         to terminate the book-entry system through the Depositary, or (iii)
         there shall have occurred and be continuing an Event of Default.

                (c) If any Global Security is to be exchanged for other
         Securities or cancelled in whole, it shall be surrendered by or on
         behalf of the Depositary or its nominee to the Securities Registrar for
         exchange or cancellation as provided in this Article III. If any Global
         Security is to be exchanged for other Securities or cancelled in part,
         or if another Security is to be exchanged in whole or in part for a
         beneficial interest in any Global Security, then either (i) such Global
         Security shall be so surrendered for exchange or cancellation as
         provided in this Article III or (ii) the principal amount thereof shall
         be reduced, subject to Section 3.6(b)(v), or increased by an amount
         equal to the portion thereof to be so exchanged or cancelled, or equal
         to the principal amount of such other Security to be so exchanged for a
         beneficial interest therein, as the case may be, by means of an
         appropriate adjustment made on the records of the Securities Registrar,
         whereupon the Trustee, in accordance with the Applicable Procedures,
         shall instruct the Depositary or its authorized representative to make
         a corresponding adjustment to its records. Upon any such surrender or
         adjustment of a Global Security by the Depositary, accompanied by
         registration instructions, the Trustee shall, subject to Section 3.6(b)
         and as otherwise provided in this Article III, authenticate and deliver
         any Securities issuable in exchange for such Global Security (or any
         portion thereof) in accordance with the instructions of the Depositary.
         The Trustee shall not be liable for any delay in delivery of such
         instructions and may conclusively rely on, and shall be fully protected
         in relying on, such instructions.

                                       - 37 -


                (d) Every Security authenticated and delivered upon registration
         of transfer of, or in exchange for or in lieu of, a Global Security or
         any portion thereof, whether pursuant to this Article III, Section 9.6
         or 11.6 or otherwise, shall be authenticated and delivered in the form
         of, and shall be, a Global Security, unless such Security is registered
         in the name of a Person other than the Depositary for such Global
         Security or a nominee thereof.

                (e) The Depositary or its nominee, as the registered owner of a
         Global Security, shall be the Holder of such Global Security for all
         purposes under this Indenture and the Securities, and owners of
         beneficial interests in a Global Security shall hold such interests
         pursuant to the Applicable Procedures. Accordingly, any such owner's
         beneficial interest in a Global Security shall be shown only on, and
         the transfer of such interest shall be effected only through, records
         maintained by the Depositary or its nominee or agent. Neither the
         Trustee nor the Securities Registrar shall have any liability in
         respect of any transfers effected by the Depositary.

                (f) The rights of owners of beneficial interests in a Global
         Security shall be exercised only through the Depositary and shall be
         limited to those established by law and agreements between such owners
         and the Depositary and/or its Agent Members.

                SECTION 3.6.   Registration, Transfer and Exchange
                               Generally; Certain Transfers and Exchanges;
                               Securities Act Legends.

                (a) The Company shall cause to be kept at the Corporate Trust
         Office of the Trustee a register in which, subject to such reasonable
         regulations as it may prescribe, the Company shall provide for the
         registration of Securities and transfers of Securities. Such register
         is herein sometimes referred to as the "Securities Register." The
         Trustee is hereby appointed "Securities Registrar" for the purpose of
         registering Securities and transfers of Securities as herein provided.

                Upon surrender for registration of transfer of any Security at
         the offices or agencies of the Company designated for that purpose, the
         Company shall execute, and the Trustee shall authenticate and deliver,
         in the name of the designated transferee or transferees, one or more
         new Securities of the same series of any authorized denominations of
         like tenor and aggregate principal amount and bearing such restrictive
         legends as may be required by this Indenture.

                At the option of the Holder, Securities may be exchanged for
         other Securities of the same series of any authorized denominations, of
         like tenor and aggregate principal amount and
<PAGE>   44

                                       - 38 -


         bearing such restrictive legends as may be required by this Indenture,
         upon surrender of the Securities to be exchanged at such office or
         agency. Whenever any securities are so surrendered for exchange, the
         Company shall execute, and the Trustee shall authenticate and deliver,
         the Securities that the Holder making the exchange is entitled to
         receive.

                All Securities issued upon any transfer or exchange of
         Securities shall be the valid obligations of the Company, evidencing
         the same debt, and entitled to the same benefits under this Indenture,
         as the Securities surrendered upon such transfer or exchange.

                Every Security presented or surrendered for transfer or exchange
         shall (if so required by the Company or the Trustee) be duly endorsed,
         or be accompanied by a written instrument of transfer in form
         satisfactory to the Company and the Securities Registrar, duly executed
         by the Holder thereof or such Holder's attorney duly authorized in
         writing.

                No service charge shall be made to a Holder for any transfer or
         exchange of Securities, but the Company may require payment of a sum
         sufficient to cover any tax or other governmental charge that may be
         imposed in connection with any transfer or exchange of Securities.

                Neither the Company nor the Trustee shall be required, pursuant
         to the provisions of this Section, (i) to issue, register the transfer
         of or exchange any Security of any series during a period beginning at
         the opening of business 15 days before the day of selection for
         redemption of Securities of that series pursuant to Article XI and
         ending at the close of business on the day of mailing of the notice of
         redemption, or (ii) to register the transfer of or exchange any
         Security so selected for redemption in whole or in part, except, in the
         case of any such Security to be redeemed in part, any portion thereof
         not to be redeemed.

                (b) Certain Transfers and Exchanges. Notwithstanding any other
         provision of this Indenture, transfers and exchanges of Securities and
         beneficial interests in a Global Security shall be made only in
         accordance with this Section 3.6(b).

                     (i) Restricted Non-Global Security to Global Security. If
         the Holder of a Restricted Security (other than a Global Security)
         wishes at any time to transfer all or any portion of such Security to a
         Person who wishes to take delivery thereof in the form of a beneficial
         interest in a Global Security, such transfer may be effected only in
         accordance with the provisions of this clause (b)(i) and subject to the
         Applicable Procedures. Upon receipt by the Securities Registrar of (A)
         such Security as provided in Section 3.6(a) and instructions
         satisfactory to the
<PAGE>   45

                                       - 39 -


         Securities Registrar directing that a beneficial interest in the Global
         Security in a specified principal amount not greater than the principal
         amount of such Security be credited to a specified Agent Member's
         account and (B) a Restricted Securities Certificate duly executed by
         such Holder or such Holder's attorney duly authorized in writing, then
         the Securities Registrar shall cancel such Security (and issue a new
         Security in respect of any untransferred portion thereof) as provided
         in Section 3.6(a) and increase the aggregate principal amount of the
         Global Security by the specified principal amount as provided in
         Section 3.5(c).

                     (ii) Non-Global Security to Non-Global Security. A Security
                that is not a Global Security may be transferred, in whole or in
                part, to a Person who takes delivery in the form of another
                Security that is not a Global Security as provided in Section
                3.6(a), provided that if the Security to be transferred in whole
                or in part is a Restricted Security, the Securities Registrar
                shall have received a Restricted Securities Certificate duly
                executed by the transferor Holder or such Holder's attorney duly
                authorized in writing.

                     (iii)  Exchanges Between Global Security and Non-
                Global Security. A beneficial interest in a Global Security
                may be exchanged for a Security that is not a Global Security
                as provided in Section 3.5.

                     (iv) Certain Initial Transfers of Non-Global Securities. In
                the case of Securities initially issued other than in global
                form, an initial transfer or exchange of such Securities that
                does not involve any change in beneficial ownership may be made
                to an Institutional Accredited Investor or Investors as if such
                transfer or exchange were not an initial transfer or exchange;
                provided that written certification shall be provided by the
                transferee and transferor of such Securities to the Securities
                Registrar that such transfer or exchange does not involve a
                change in beneficial ownership.

                (c)  Restricted Securities Legend.  Except as set forth
         below, all Securities shall bear a Restricted Securities Legend:

                     (i) subject to the following clauses of this Section
                3.6(c), a Security or any portion thereof that is exchanged,
                upon transfer or otherwise, for a Global Security or any portion
                thereof shall bear the Restricted Securities Legend while
                represented thereby;

                     (ii) subject to the following clauses of this Section
                3.6(c), a new Security which is not a Global Security and is
                issued in exchange for another Security
<PAGE>   46

                                       - 40 -


                (including a Global Security) or any portion thereof, upon
                transfer or otherwise, shall, if such new Security is required
                pursuant to Section 3.6(b)(ii) or (iii) to be issued in the form
                of a Restricted Security, bear a Restricted Securities Legend;

                     (iii) a new Security (other than a Global Security) that
                does not bear a Restricted Securities Legend may be issued in
                exchange for or in lieu of a Restricted Security or any portion
                thereof that bears such a legend if, in the Company's judgment,
                placing such a legend upon such new Security is not necessary to
                ensure compliance with the registration requirements of the
                Securities Act, and the Trustee, at the written direction of the
                Company in the form of an Officers' Certificate, shall
                authenticate and deliver such a new Security as provided in this
                Article III;

                     (iv) notwithstanding the foregoing provisions of this
                Section 3.6(c), a Successor Security of a Security that does not
                bear a Restricted Securities Legend shall not bear such form of
                legend unless the Company has reasonable cause to believe that
                such Successor Security is a "restricted security" within the
                meaning of Rule 144, in which case the Trustee, at the written
                direction of the Company in the form of an Officers'
                Certificate, shall authenticate and deliver a new Security
                bearing a Restricted Securities Legend in exchange for such
                Successor Security as provided in this Article III; and

                     (v) Securities distributed to a holder of Capital
                Securities upon dissolution of an Issuer Trust shall bear a
                Restricted Securities Legend if the Capital Securities so
                held bear a similar legend.

                SECTION 3.7.   Mutilated, Lost and Stolen Securities.

                If any mutilated Security is surrendered to the Trustee together
         with such security or indemnity as may be required by the Company or
         the Trustee to save each of them harmless, the Company shall execute
         and the Trustee shall authenticate and deliver in exchange therefor a
         new Security of the same series, of like tenor and aggregate principal
         amount, bearing the same legends, and bearing a number not
         contemporaneously outstanding.

                If there shall be delivered to the Company and to the Trustee
         (i) evidence to their satisfaction of the destruction, loss or theft of
         any Security, and (ii) such security or indemnity as may be required by
         them to save each of them harmless, then, in the absence of notice to
         the Company or the Trustee that such Security has been acquired by a
         bona fide purchaser, the Company
<PAGE>   47

                                       - 41 -


         shall execute and upon its request the Trustee shall authenticate and
         deliver, in lieu of any such destroyed, lost or stolen Security, a new
         Security of the same series, of like tenor and aggregate principal
         amount and bearing the same legends as such destroyed, lost or stolen
         Security, and bearing a number not contemporaneously outstanding.

                If any such mutilated, destroyed, lost or stolen Security has
         become or is about to become due and payable, the Company in its
         discretion may, instead of issuing a new Security, pay such Security.

                Upon the issuance of any new Security under this Section 3.7,
         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.

                Every new Security issued pursuant to this Section in lieu of
         any destroyed, lost or stolen Security shall constitute an original
         additional contractual obligation of the Company, whether or not the
         destroyed, lost or stolen Security shall be at any time enforceable by
         anyone, and shall be entitled to all the benefits of this Indenture
         equally and proportionately with any and all other Securities of such
         series duly issued hereunder.

                The provisions of this Section are exclusive and shall preclude
         (to the extent lawful) all other rights and remedies with respect to
         the replacement or payment of mutilated, destroyed, lost or stolen
         Securities.

                SECTION 3.8.   Payment of Interest and Additional Interest;
                               Interest Rights Preserved.

                Interest and Additional Interest on any Security of any series
         that is payable, and is punctually paid or duly provided for, on any
         Interest Payment Date, shall be paid to the Person in whose name that
         Security (or one or more Predecessor Securities) is registered at the
         close of business on the Regular Record Date for such interest in
         respect of Securities of such series, except that, unless otherwise
         provided in the Securities of such series, interest payable on the
         Stated Maturity of the principal of a Security shall be paid to the
         Person to whom principal is paid. The initial payment of interest on
         any Security of any series that is issued between a Regular Record Date
         and the related Interest Payment Date shall be payable as provided in
         such Security or in the Board Resolution pursuant to Section 3.1 with
         respect to the related series of Securities.

                Any interest on any Security that is due and payable, but is not
         timely paid or duly provided for, on any Interest Payment

                                       - 42 -


         Date for Securities of such series (herein called "Defaulted
         Interest"), shall forthwith cease to be payable to the registered
         Holder on the relevant Regular Record Date by virtue of having been
         such Holder, and such Defaulted Interest may be paid by the Company, at
         its election in each case, as provided in clause (1) or (2) below:

                     (1) The Company may elect to make payment of any Defaulted
                Interest to the Persons in whose names the Securities of such
                series in respect of which interest is in default (or their
                respective Predecessor Securities) are registered at the close
                of business on a Special Record Date for the payment of such
                Defaulted Interest, which shall be fixed in the following
                manner. The Company shall notify the Trustee in writing of the
                amount of Defaulted Interest proposed to be paid on each
                Security and the date of the proposed payment, and which shall
                be fixed at the same time the Company shall deposit with the
                Trustee an amount of money equal to the aggregate amount
                proposed to be paid in respect of such Defaulted Interest or
                shall make arrangements satisfactory to the Trustee for such
                deposit prior to the date of the proposed payment, such money
                when deposited to be held in trust for the benefit of the
                Persons entitled to such Defaulted Interest as in this clause
                provided. Thereupon, the Trustee shall fix a Special Record Date
                for the payment of such Defaulted Interest, which shall be not
                more than 15 days and not less than 10 days prior to the date of
                the proposed payment and not less than 10 days after the receipt
                by the Trustee of the notice of the proposed payment. The
                Trustee shall promptly notify the Company of such Special Record
                Date and, in the name and at the expense of the Company, shall
                cause notice of the proposed payment of such Defaulted Interest
                and the Special Record Date therefor to be mailed, first class,
                postage prepaid, to each Holder of a Security of such series at
                the address of such Holder as it appears in the Securities
                Register not less than 10 days prior to such Special Record
                Date. The Trustee may, in its discretion, in the name and at the
                expense of the Company, cause a similar notice to be published
                at least once in a newspaper, customarily published in the
                English language on each Business Day and of general circulation
                in the Borough of Manhattan, The City of New York, but such
                publication shall not be a condition precedent to the
                establishment of such Special Record Date. Notice of the
                proposed payment of such Defaulted Interest and the Special
                Record Date therefor having been mailed as aforesaid, such
                Defaulted Interest shall be paid to the Persons in whose names
                the Securities of such series (or their respective Predecessor
                Securities) are registered on such Special Record Date and
<PAGE>   49

                                       - 43 -


                shall no longer be payable pursuant to the following clause
                (2).

                     (2) The Company may make payment of any Defaulted Interest
                in any other lawful manner not inconsistent with the
                requirements of any securities exchange on which the Securities
                of the series in respect of which interest is in default may be
                listed and, upon such notice as may be required by such exchange
                (or by the Trustee if the Securities are not listed), if, after
                notice given by the Company to the Trustee of the proposed
                payment pursuant to this clause 2, such payment shall be deemed
                practicable by the Trustee.

                Subject to the foregoing provisions of this Section, each
                Security delivered under this Indenture upon transfer of or in
                exchange for or in lieu of any other Security shall carry the
                rights to interest accrued and unpaid, and to accrue interest,
                that were carried by such other Security.

                SECTION 3.9.   Persons Deemed Owners.

                The Company, the Trustee and any agent of the Company or the
         Trustee shall treat the Person in whose name any Security is registered
         as the owner of such Security for the purpose of receiving payment of
         principal of and (subject to Section 3.8) any interest on such Security
         and for all other purposes whatsoever, whether or not such Security be
         overdue, and neither the Company, the Trustee nor any agent of the
         Company or the Trustee shall be affected by notice to the contrary.

                No holder of any beneficial interest in any Global Security held
         on its behalf by a Depositary shall have any rights under this
         Indenture with respect to such Global Security, and such Depositary may
         be treated by the Company, the Trustee and any agent of the Company or
         the Trustee as the owner of such Global Security for all purposes
         whatsoever. Notwithstanding the foregoing, nothing herein shall prevent
         the Company, the Trustee or any agent of the Company or the Trustee
         from giving effect to any written certification, proxy or other
         authorization furnished by a Depositary or impair, as between a
         Depositary and such holders of beneficial interests, the operation of
         customary practices governing the exercise of the rights of the
         Depositary (or its nominee) as Holder of any Security.

                SECTION 3.10.  Cancellation.

                All Securities surrendered for payment, redemption, transfer or
         exchange shall, if surrendered to any Person other than the Trustee, be
         delivered to the Trustee, and any such Securities and Securities
         surrendered directly to the Trustee for
<PAGE>   50

                                       - 44 -


         any such purpose shall be promptly canceled by it. The Company may at
         any time deliver to the Trustee for cancellation any Securities
         previously authenticated and delivered hereunder that the Company may
         have acquired in any manner whatsoever, and all Securities so delivered
         shall be promptly canceled by the Trustee. No Securities shall be
         authenticated in lieu of or in exchange for any Securities canceled as
         provided in this Section, except as expressly permitted by this
         Indenture. All canceled Securities shall be destroyed by the Trustee
         and the Trustee shall deliver to the Company a certificate of such
         destruction.

                SECTION 3.11.  Computation of Interest.

                Except as otherwise specified as contemplated by Section 3.1 for
         Securities of any series, interest on the Securities of each series for
         any period shall be computed on the basis of a 360-day year of twelve
         30-day months and the actual number of days elapsed in any partial
         month in such period, and interest on the Securities of each series for
         a full period shall be computed by dividing the rate per annum by the
         number of interest periods that together constitute a full twelve
         months.

                SECTION 3.12.  Deferrals of Interest Payment Dates.

                If specified as contemplated by Section 2.1 or Section 3.1 with
         respect to the Securities of a particular series, so long as no Event
         of Default has occurred and is continuing, the Company shall have the
         right, at any time during the term of such series, from time to time to
         defer the payment of interest on such Securities for such period or
         periods (each an "Extension Period") not to exceed the number of
         consecutive quarterly, semi-annual or other periods that equal five
         years with respect to each Extension Period, during which Extension
         Periods the Company shall, if so specified as contemplated by Section
         3.1, have the right to make partial payments of interest on any
         Interest Payment Date. No Extension Period shall end on a date other
         than an Interest Payment Date. At the end of any such Extension Period,
         the Company shall pay all interest then accrued and unpaid on the
         Securities (together with Additional Interest thereon, if any, at the
         rate specified for the Securities of such series to the extent
         permitted by applicable law); provided, however, that no Extension
         Period shall extend beyond the Stated Maturity of the principal of the
         Securities of such series; and provided further, however, that, during
         any such Extension Period, the Company shall 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, or (ii) make any payment of principal of or interest or premium,
         if any, on or repay, repurchase or redeem any debt securities of the
         Company that rank pari passu in all respects with or junior in interest
         to the Securities of such series (other than (a) repurchases,
         redemptions

         or other acquisitions of shares of capital stock of the Company in
         connection with any employment contract, benefit plan or other similar
         arrangement with or for the benefit of any one or more employees,
         officers, directors or consultants, in connection with a dividend
         reinvestment or stockholder stock purchase plan or in connection with
         the issuance of capital stock of the Company (or securities convertible
         into or exercisable for such capital stock) as consideration in an
         acquisition transaction entered into prior to the applicable Extension
         Period, (b) as a result of an exchange or conversion of any class or
         series of the Company's capital stock (or any capital stock of a
         Subsidiary of the Company) for any class or series of the Company's
         capital stock or of any class or series of the Company's indebtedness
         for any class or series of the Company's capital stock, (c) the
         purchase of fractional interests in shares of the Company's capital
         stock pursuant to the conversion or exchange provisions of such capital
         stock or the security being converted or exchanged, (d) any declaration
         of a dividend in connection with any Rights Plan, or the issuance of
         rights, stock or other property under any Rights Plan, or the
         redemption or repurchase of rights pursuant thereto, or (e) any
         dividend in the form of stock, warrants, options or other rights where
         the dividend stock or the stock issuable upon exercise of such
         warrants, options or other rights is the same stock as that on which
         the dividend is being paid or ranks pari passu with or junior to such
         stock). Prior to that termination of any such Extension Period, the
         Company may further defer the payment of interest, provided that no
         Event of Default has occurred and is continuing and provided further,
         that no Extension Period shall exceed the period or periods specified
         in such Securities, extend beyond the Stated Maturity of the principal
         of such Securities or end on a date other than an Interest Payment
         Date. Upon the termination of any such Extension Period and upon the
         payment of all accrued and unpaid interest and any Additional Interest
         then due on any Interest Payment Date, the Company may elect to begin a
         new Extension Period, subject to the above conditions. No interest or
         Additional Interest shall be due and payable during an Extension
         Period, except at the end thereof, but each installment of interest
         that would otherwise have been due and payable during such Extension
         Period shall bear Additional Interest as and to the extent as may be
         specified as contemplated by Section 3.1. The Company shall give the
         Holders of the Securities of such series and the Trustee notice of its
         election to begin any such Extension Period at least one Business Day
         prior to the next succeeding Interest Payment Date on which interest on
         Securities of such series would be payable but for such deferral or,
         with respect to any Securities of a series issued to an Issuer Trust,
         so long as any such Securities are held by such Issuer Trust, at least
         one Business Day prior to the earlier of (i) the next succeeding date
         on which Distributions on the Capital Securities of such Issuer Trust
         would be payable but for such deferral, and (ii) the date on which the
         Property Trustee of such Issuer Trust is required to
<PAGE>   52

                                       - 46 -


         give notice to holders of such Capital Securities of the record date or
         the date such Distributions are payable, but in any event not less than
         one Business Day prior to such record date.

                The Trustee shall promptly give notice of the Company's election
         to begin any such Extension Period to the Holders of the Outstanding
         Securities of such series.

                SECTION 3.13.  Right of Set-Off.

                With respect to the Securities of a series initially issued to
         an Issuer Trust, notwithstanding anything to the contrary herein, the
         Company shall have the right to set off any payment it is otherwise
         required to make in respect of any such Security to the extent the
         Company has theretofore made, or is concurrently on the date of such
         payment making, a payment under the Guarantee relating to such Security
         or to a holder of Capital Securities pursuant to an action undertaken
         under Section 5.8 of this Indenture.

                SECTION 3.14.  Agreed Tax Treatment.

                Each Security issued hereunder shall provide that the Company
         and, by its acceptance of a Security or a beneficial interest therein,
         the Holder of, and any Person that acquires a beneficial interest in,
         such Security agree that for United States Federal, state and local tax
         purposes it is intended that such Security constitutes indebtedness.

                SECTION 3.15.  Shortening or Extension of Stated Maturity.

                If specified as contemplated by Section 2.1 or Section 3.1 with
         respect to the Securities of a particular series, the Company shall
         have the right to (i) shorten the Stated Maturity of the principal of
         the Securities of such series at any time to any date and (ii) extend
         the Stated Maturity of the principal of the Securities of such series
         at any time at its election for one or more periods, provided that, if
         the Company elects to exercise its right to extend the Stated Maturity
         of the principal of the Securities of such series pursuant to clause
         (ii) above, at the time such election is made and at the time of
         extension, such conditions as may be specified in such Securities shall
         have been satisfied.

                SECTION 3.16 CUSIP Numbers.

                The Company, in issuing the Securities, may use "CUSIP" numbers
         (if then generally in use), and, if so, the Trustee shall use "CUSIP"
         numbers in notice of redemption and other similar or related materials
         as a convenience to Holders; provided that any such notice or other
         materials may state that no representation is
<PAGE>   53

                                       - 47 -


         made as to the correctness of such numbers either as printed on the
         Securities or as contained in any notice of redemption or other
         materials and that reliance may be placed only on the other
         identification numbers printed on the Securities, and any such
         redemption shall not be affected by any defect in or omission of such
         numbers.

                                   ARTICLE IV
                           SATISFACTION AND DISCHARGE

                SECTION 4.1.   Satisfaction and Discharge of Indenture.

                This Indenture shall, upon Company Request, cease to be of
         further effect (except as to any surviving rights of registration of
         transfer or exchange of Securities herein expressly provided for and as
         otherwise provided in this Section 4.1) and the Trustee, on demand of
         and at the expense of the Company, shall execute proper instruments
         acknowledging satisfaction and discharge of this Indenture, when

                     (1)  either

                          (A) all Securities theretofore authenticated and
                     delivered (other than (i) Securities that have been
                     destroyed, lost or stolen and that have been replaced or
                     paid as provided in Section 3.7 and (ii) Securities for
                     whose payment money has theretofore been deposited in trust
                     or segregated and held in trust by the Company and
                     thereafter repaid to the Company or discharged from such
                     trust, as provided in Section 10.3) have been delivered to
                     the Trustee for cancellation; or

                          (B)  all such Securities not theretofore
                     delivered to the Trustee for cancellation

                               (i)    have become due and payable, or

                               (ii)   will become due and payable at their
                          Stated Maturity within one year of the date of
                          deposit, or

                               (iii) are to be called for redemption within one
                          year under arrangements satisfactory to the Trustee
                          for the giving of notice of redemption by the Trustee
                          in the name, and at the expense, of the Company,


                and the Company, in the case of subclause (B)(i), (ii) or
                (iii) above, has deposited or caused to be deposited with

                                       - 48 -


                the Trustee as trust funds in trust for such purpose an amount
                in the currency or currencies in which the Securities of such
                series are payable sufficient to pay and discharge the entire
                indebtedness on such Securities not theretofore delivered to the
                Trustee for cancellation, for the principal (and premium, if
                any) and interest (including any Additional Interest) to the
                date of such deposit (in the case of Securities that have become
                due and payable) or to the Stated Maturity or Redemption Date,
                as the case may be;

                     (2)  the Company has paid or caused to be paid all
                other sums payable hereunder by the Company; and

                     (3) the Company has delivered to the Trustee an Officers'

                respect thereof, when it becomes due and payable, and
                continuance of such default for a period of 30 days (subject to
                the deferral of any due date in the case of an Extension
                Period); or

                     (2) default in the payment of the principal of (or

                Maturity; or

                     (3) failure on the part of the Company duly to observe or
                perform any other of the covenants or agreements on the part of
                the Company in the Securities of that series or in this
                Indenture for a period of 90 days after the date on which
                written notice of such failure, requiring the Company to remedy
                the same, 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 aggregate principal amount of
                the Outstanding Securities of that series; or

                     (4) the occurrence of the appointment of a receiver or
                other similar official in any liquidation, insolvency or similar
                proceeding with respect to the Company or all or substantially

                               Annulment.

                If an Event of Default (other than an Event of Default specified
         in Section 5.1(4)) with respect to Securities of any series at the time
         Outstanding occurs and is continuing, then, and in every such case, the
         Trustee or the Holders of not less than 25% in aggregate principal
         amount of the Outstanding Securities of that series may declare the
         principal amount (or, if the Securities of that series are Discount
         Securities, such portion of the principal amount as may be specified in
         the terms of that series) of all the Securities of that series to be
         due and payable

                                       - 50 -


         immediately, by a notice in writing to the Company (and to the Trustee
         if given by Holders), provided that, in the case of the Securities of a
         series issued to an Issuer Trust, if, upon an Event of Default, the
         Trustee or the Holders of not less than 25% in principal amount of the
         Outstanding Securities of such series fail to declare the principal of
         all the Outstanding Securities of such series to be immediately due and
         payable, the holders of at least 25% in aggregate Liquidation Amount
         (as defined in the related Trust Agreement) of the related series of
         Capital Securities issued by such Issuer Trust then outstanding shall
         have the right to make such declaration by a notice in writing to the
         Company and the Trustee; and upon any such declaration such principal
         amount (or specified portion thereof) of and the accrued interest
         (including any Additional Interest) on all the Securities of such
         series shall become immediately due and payable. If an Event of Default
         specified in Section 5.1(4) with respect to Securities of any series at
         the time Outstanding occurs, the principal amount of all the Securities
         of such series (or, if the Securities of such series are Discount
         Securities, such portion of the principal amount of such Securities as
         may be specified by the terms of that series) shall automatically, and
         without any declaration or other action on the part of the Trustee or
         any Holder, become immediately due and payable. Payment of principal
         and interest (including any Additional Interest) on such Securities
         shall remain subordinated to the extent provided in Article XIII
         notwithstanding that such amount shall become immediately due and
         payable as herein provided.

                At any time after such a declaration of acceleration with
         respect to Securities of any series has been made and before a judgment
         or decree for payment of the money due has been obtained by the Trustee
         as hereinafter in this Article provided, the Holders of a majority in
         aggregate principal amount of the Outstanding Securities of that
         series, by written notice to the Company and the Trustee, may rescind
         and annul such declaration and its consequences if:

                     (1)  the Company has paid or deposited with the
                Trustee a sum sufficient to pay:

                          (A)  all overdue installments of interest on all
                Securities of such series;

                          (B)  any accrued Additional Interest on all
                Securities of such series;

                          (C) the principal of (and premium, if any, on) any
                Securities of such series that have become due otherwise than by
                such declaration of acceleration and interest and Additional
                Interest thereon at the rate borne by the Securities; and
<PAGE>   57

                                       - 51 -



                          (D) all sums paid or advanced by the Trustee hereunder
                and the reasonable compensation, expenses, disbursements and
                advances of the Trustee, its agents and counsel; and

                     (2) all Events of Default with respect to Securities of
                that series, other than the non-payment of the principal of
                Securities of that series that has become due solely by such
                acceleration, have been cured or waived as provided in Section
                5.13.


                In the case of Securities of a series initially issued to an
         Issuer Trust, if the Holders of such Securities fail to annul such
         declaration and waive such default, the holders of a majority in
         aggregate Liquidation Amount (as defined in the related Trust
         Agreement) of the related series of Capital Securities issued by such
         Issuer Trust then outstanding shall also have the right to rescind and
         annul such declaration and its consequences by written notice to the
         Company and the Trustee, subject to the satisfaction of the conditions
         set forth in clauses (1) and (2) above of this section 5.2.

                No such rescission shall affect any subsequent default or impair
         any right consequent thereon.

                SECTION 5.3.   Collection of Indebtedness and Suits for
                               Enforcement by Trustee.

                The Company covenants that if:

                     (1) default is made in the payment of any installment of
                interest (including any Additional Interest) on any Security of
                any series when such interest becomes due and payable and such
                default continues for a period of 30 days, or

                     (2)  default is made in the payment of the principal
                of (and premium, if any, on) any Security at the Maturity
                thereof,

                the Company will, upon demand of the Trustee, pay to the
                Trustee, for the benefit of the Holders of such Securities, the
                whole amount then due and payable on such Securities for
                principal (and premium, if any) and interest (including any
                Additional Interest), and, in addition thereto,all amounts owing
                the Trustee under Section 6.7.
<PAGE>   58

                                       - 52 -


                If the Company fails to pay such amounts forthwith upon such
         demand, the Trustee, in its own name and as trustee of an express
         trust, may institute a judicial proceeding for the collection of the
         sums so due and unpaid, and may prosecute such proceeding to judgment
         or final decree, and may enforce the same against the Company or any
         other obligor upon such Securities and collect the monies adjudged or
         decreed to be payable in the manner provided by law out of the property
         of the Company or any other obligor upon the Securities, wherever
         situated.

                If an Event of Default with respect to Securities of any series
         occurs and is continuing, the Trustee may in its discretion proceed to
         protect and enforce its rights and the rights of the Holders of
         Securities of such series by such appropriate judicial proceedings as
         the Trustee shall deem most effectual to protect and enforce any such
         rights, whether for the specific enforcement of any covenant or
         agreement in this Indenture or in aid of the exercise of any power
         granted herein, or to enforce any other proper remedy.

                SECTION 5.4.   Trustee May File Proofs of Claim.

                In case of any receivership, insolvency, liquidation,
         bankruptcy, reorganization, arrangement, adjustment, composition or
         other judicial or administrative proceeding relative to the Company or
         any other obligor upon the Securities or the property of the Company or
         of such other obligor or their creditors,

                (a) the Trustee (irrespective of whether the principal of the
         Securities of any series shall then be due and payable as therein
         expressed or by declaration or otherwise and irrespective of whether
         the Trustee shall have made any demand on the Company for the payment
         of overdue principal (and premium, if any) or interest (including any
         Additional Interest)) shall be entitled and empowered, by intervention
         in such proceeding or otherwise,

                     (i) to file and prove a claim for the whole amount of
                principal (and premium, if any) and interest (including any
                Additional Interest) owing and unpaid in respect to the
                Securities and to file such other papers or documents as may be
                necessary or advisable and to take any and all actions as are
                authorized under the Trust Indenture Act in order to have the
                claims of the Holders and any predecessor to the Trustee under
                Section 6.7 allowed in any such judicial or administrative
                proceedings; and

                     (ii) in particular, the Trustee shall be authorized to
                collect and receive any monies or other property payable or
                deliverable on any such claims and to distribute the same in
                accordance with Section 5.6; and

                                       - 53 -


                (b) any custodian, receiver, assignee, trustee, liquidator,
         sequestrator, conservator (or other similar official) in any such
         judicial or administrative proceeding is hereby authorized by each
         Holder to make such payments to the Trustee for distribution in
         accordance with Section 5.6, and in the event that the Trustee shall
         consent to the making of such payments directly to the Holders, to pay
         to the Trustee any amount due to it and any predecessor Trustee under
         Section 6.7.

                Nothing herein contained shall be deemed to authorize the
         Trustee to authorize or consent to accept or adopt on behalf of any
         Holder any plan of reorganization, arrangement, adjustment or
         composition affecting the Securities or the rights of any Holder
         thereof, or to authorize the Trustee to vote in respect of the claim of
         any Holder in any such proceeding; provided, however, that the Trustee
         may, on behalf of the Holders, vote for the election of a trustee in
         bankruptcy or similar official and be a member of a creditors' or other
         similar committee.

                SECTION 5.5.   Trustee May Enforce Claim Without Possession
                               of Securities.

                All rights of action and claims under this Indenture or the
         Securities may be prosecuted and enforced by the Trustee without the
         possession of any of the Securities or the production thereof in any
         proceeding relating thereto, and any such proceeding instituted by the
         Trustee shall be brought in its own name as trustee of an express
         trust, and any recovery of judgment shall, subject to Article XIII and
         after provision for the payment of all the amounts owing the Trustee
         and any predecessor Trustee under Section 6.7, its agents and counsel,
         be for the ratable benefit of the Holders of the Securities in respect
         of which such judgment has been recovered.

                SECTION 5.6 Application of Money Collected.

                Any money or property collected or to be applied by the Trustee
         with respect to a series of Securities pursuant to this Article shall

         Trustee and, in case of the distribution of such money or property on
         account of principal (or premium, if any) or interest (including any

         notation thereon of the payment if only partially paid and upon
         surrender thereof if fully paid:

                FIRST:    To the payment of all amounts due the Trustee and
         any predecessor Trustee under Section 6.7;

         principal (and premium, if any) and interest (including any Additional
         Interest) in respect of which or for the 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 series of
         Securities for principal (and premium, if any) and interest (including
         any Additional Interest), respectively; and

                THIRD:    The balance, if any, to the Person or Persons
         entitled thereto.

                SECTION 5.7 Limitation on Suits.

                Subject to Section 5.8, no Holder of any Securities of any
         series shall have any right to institute any proceeding, judicial or
         otherwise, with respect to this Indenture or for the appointment of a
         receiver, assignee, trustee, liquidator, sequestrator (or other similar
         official) or for any other remedy hereunder, unless:

                     (1) such Holder has previously given written notice to the
                Trustee of a continuing Event of Default with respect to the
                Securities of that series;

                     (2) the Holders of not less than 25% in aggregate principal
                amount of the Outstanding Securities of that series shall have
                made written request to the Trustee to institute proceedings in
                respect of such Event of Default in its own name as Trustee
                hereunder;

                     (3) such Holder or Holders have offered to the Trustee
                reasonable indemnity against the costs, expenses and liabilities
                to be incurred in compliance with such request;

                     (4) the Trustee for 60 days after its receipt of such
                notice, request and offer of indemnity has failed to institute
                any such proceeding; and

                     (5) no direction inconsistent with such written request has

                Holders of a majority in aggregate principal amount of the
                Outstanding Securities of that series;

                it being understood and intended that no one or more of such
                Holders shall have any right in any manner whatever by virtue
                of, or by availing itself of, any provision of this Indenture to
                affect, disturb or prejudice the rights of any other Holders of

                except in the manner herein provided and for the equal and
                ratable benefit of all such Holders.


                SECTION 5.8.   Unconditional Right of Holders to Receive

         redemption, on the Redemption Date) and to institute suit for the
         enforcement of any such payment, and such right shall not be impaired
         without the consent of such Holder. In the case of Securities of a
         series issued to an Issuer Trust, any registered holder of the series
         of Capital Securities issued by such Issuer Trust shall have the right,
         upon the occurrence of an Event of Default described in Section 5.1(1)
         or 5.1(2), to institute a suit directly against the Company for
         enforcement of payment to such holder of principal of (premium, if any)

         issued by any Issuer Trust has instituted any proceeding to enforce any
         right or remedy under this Indenture and such proceeding has been
         discontinued or abandoned for any reason, or has been determined
         adversely to the Trustee, such Holder or such holder of Capital
         Securities, then, and in every such case, the Company, the Trustee,
         such Holders and such holder of Capital Securities shall, subject to
         any determination in such proceeding, be restored severally and
         respectively to their former positions hereunder, and thereafter all
         rights and remedies of the Trustee, such Holder and such holder of
         Capital Securities shall continue as though no such proceeding had been
         instituted.

                SECTION 5.10.  Rights and Remedies Cumulative.

                Except as otherwise provided in the last paragraph of Section
         3.7, no right or remedy herein conferred upon or reserved to the
         Trustee or the Holders is intended to be exclusive of any other right
         or remedy, and every right and remedy shall, to the
<PAGE>   62

                                       - 56 -


         extent permitted by law, be cumulative and in addition to every other
         right and remedy given hereunder or now or hereafter existing at law or
         in equity or otherwise. The assertion or employment of any right or
         remedy hereunder, or otherwise, shall not prevent the concurrent
         assertion or employment of any other appropriate right or remedy.

                SECTION 5.11.  Delay or Omission Not Waiver.

                No delay or omission of the Trustee, any Holder of any Security
         with respect to the Securities of the related series or any holder of
         any Capital Security to exercise any right or remedy accruing upon any
         Event of Default with respect to the Securities of the related series
         shall impair any such right or remedy or constitute a waiver of any
         such Event of Default or an acquiescence therein.

                Every right and remedy given by this Article or by law to the
         Trustee or to the Holders and the right and remedy given to the holders
         of Capital Securities by Section 5.8 may be exercised from time to
         time, and as often as may be deemed expedient, by the Trustee, the
         Holders or the holders of Capital Securities, as the case may be.

                SECTION 5.12.  Control by Holders.

                The Holders of not less than a majority in aggregate principal
         amount of the Outstanding Securities of any series 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, with respect to the Securities of such
         series, provided that:

                     (1)  such direction shall not be in conflict with any
                rule of law or with this Indenture,

                     (2)  the Trustee may take any other action deemed
                proper by the Trustee that is not inconsistent with such
                direction, and

                     (3) subject to the provisions of Section 6.1, the Trustee
                shall have the right to decline to follow such direction if a
                Responsible Officer or Officers of the Trustee shall, in good
                faith, determine that the proceeding so directed would be
                unjustly prejudicial to the Holders not joining in any such
                direction or would involve the Trustee in personal liability.

                SECTION 5.13.  Waiver of Past Defaults.

                The Holders of not less than a majority in aggregate principal
         amount of the Outstanding Securities of any series affected thereby
         and, in the case of any Securities of a series initially issued to an
         Issuer Trust, the holders of a majority in aggregate Liquidation Amount
         (as defined in the related Trust Agreement) of the Capital Securities
         issued by such Issuer Trust may waive any past default hereunder and
         its consequences with respect to such series except a default:

                     (1) in the payment of the principal of (or premium, if any)
                or interest (including any Additional Interest) on any Security
                of such series (unless such default has been cured and the
                Company has paid to or deposited with the Trustee a sum
                sufficient to pay all matured installments of interest
                (including Additional Interest) and all principal of (and
                premium, if any, on) all Securities of that series due otherwise
                than by acceleration), or

                     (2) in respect of a covenant or provision hereof that under
                Article IX cannot be modified or amended without the consent of
                each Holder of any Outstanding Security of such series affected.

                Any such waiver shall be deemed to be on behalf of the Holders
         of all the Securities of such series, or in the case of waiver by
         holders of Capital Securities issued by such Issuer Trust, by all
         holders of Capital Securities issued by such Issuer Trust.

                Upon any such waiver, such default shall cease to exist, and any
         Event of Default arising therefrom shall be deemed to have been cured,
         for every purpose of this Indenture, but no such waiver shall extend to
         any subsequent or other default or impair any right consequent thereon.

                SECTION 5.14.  Undertaking for Costs.

                All parties to this Indenture agree, and each Holder of any
         Security by his 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 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 shall not apply to any suit instituted
         by the
<PAGE>   64

                                       - 58 -


         Trustee, to any suit instituted by any Holder, or group of Holders,
         holding in the aggregate more than 10% in aggregate principal amount of
         the Outstanding Securities of any series, or to any suit instituted by
         any Holder for the enforcement of the payment of the principal of (or
         premium, if any) or interest (including any Additional Interest) on any
         Security on or after the respective Stated Maturities expressed in such
         Security.

                SECTION 5.15.  Waiver of Usury, Stay or Extension Laws.

                The Company covenants (to the extent that it may lawfully do so)
         that it will not at any time insist upon, or plead, or in any manner
         whatsoever claim or take the benefit or advantage of, any usury, stay
         or extension law wherever enacted, now or at any time hereafter in
         force, which may affect the covenants or the performance of this
         Indenture; and the Company (to the extent that it may lawfully do so)
         hereby expressly waives all benefit or advantage of any such law, and
         covenants that it will not hinder, delay or impede the execution of any
         power herein granted to the Trustee, but will suffer and permit the
         execution of every such power as though no such law had been enacted.


                                   ARTICLE VI
                                   THE TRUSTEE

                SECTION 6.1.   Certain Duties and Responsibilities.

                (a)  Except during the continuance of an Event of Default,

                     (1) the Trustee undertakes to perform such duties and only
                such duties as are specifically set forth in this Indenture, and
                no implied covenants or obligations shall be read into this
                Indenture against the Trustee; and

                     (2) in the absence of bad faith on its part, the Trustee
                may conclusively rely, as to the truth of the statements and the
                correctness of the opinions expressed therein, upon 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 provisions 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.


                (b) In case an Event of Default has occurred and is continuing,
         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 their
         exercise, as a prudent person would
<PAGE>   65

                                       - 59 -


         exercise or use under the circumstances in the conduct of his or
         her own affairs.

                (c) 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)  this subsection shall not be construed to limit
                the effect of subsection (a) of this Section;

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

                     (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 Holders pursuant to Section
                5.12 relating to the time, method and place of conducting any
                proceeding for any remedy available to the Trustee, or
                exercising any trust or power conferred upon the Trustee, under
                this Indenture with respect to the Securities of a series.

                (d) No provision of this Indenture shall require the Trustee to
         expend or risk its own funds or otherwise incur any financial liability
         in the performance of any of its duties hereunder, or in the exercise
         of any of its rights or powers, if there shall be reasonable grounds
         for believing that repayment of such funds or adequate indemnity
         against such risk or liability is not reasonably assured to it.

                (e) Whether or not therein expressly so provided, every
         provision of this Indenture relating to the conduct or affecting the
         liability of or affording protection to the Trustee shall be subject to
         the provisions of this Section.

                SECTION 6.2.   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 Securities of any series, the Trustee shall transmit by mail to
         all Holders of Securities of such series, as their names and addresses
         appear in the Securities 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 of (or
         premium, if any) or interest (including any Additional Interest) on any
         Security of such series, the Trustee shall be protected in withholding
         such notice if and so long as the board of directors, the executive
<PAGE>   66

                                       - 60 -


         committee or a trust committee of directors and/or Responsible Officers
         of the Trustee in good faith determines that the withholding of such
         notice is in the interests of the Holders of Securities of such series;
         and provided further, that, in the case of any default of the character
         specified in Section 5.1(3), no such notice to Holders of Securities of
         such series shall be given until at least 30 days after the occurrence
         thereof. For the purpose of this Section, the term "default" means any
         event that is, or after notice or lapse of time or both would become,
         an Event of Default with respect to Securities of such series.

                SECTION 6.3.   Certain Rights of Trustee.

                Subject to the provisions of Section 6.1:

                (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, direction, consent,
         order, bond, debenture, 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 or direction of the Company mentioned herein
         shall be sufficiently evidenced by a Company Request or Company Order
         and any resolution of the Board of Directors may be sufficiently
         evidenced by a Board Resolution;

                (c) whenever in the administration of this Indenture the Trustee
         shall deem it desirable that a matter be proved or established prior to
         taking, suffering or omitting any action hereunder, the Trustee (unless
         other evidence be herein specifically prescribed) may, in the absence
         of bad faith on its part, rely upon an Officers' Certificate;

                (d) the Trustee may consult with counsel and the advice of such
         counsel or any Opinion of 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;

                (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 or
         direction of any of the Holders pursuant to this Indenture, unless such
         Holders shall have offered to the Trustee reasonable security or
         indemnity against the costs, expenses and liabilities that might be
         incurred by it in compliance with such request or direction;

                (f) 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,
<PAGE>   67

                                       - 61 -


         request, direction, consent, order, bond, indenture, Security or other
         paper or document, but the Trustee in its discretion may make such
         inquiry or investigation into such facts or matters as it may see fit,
         and, if the Trustee shall determine to make such inquiry or
         investigation, it shall be entitled to examine the books, records and
         premises of the Company, personally or by agent or attorney; and

                (g) 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 6.4.   Not Responsible for Recitals or Issuance of
                               Securities.

                The recitals contained herein and in the Securities, except the
         Trustee's certificates of authentication, shall be taken as the
         statements of the Company, and neither the Trustee nor any
         Authenticating Agent assumes any responsibility for their correctness.
         The Trustee makes no representations as to the validity or sufficiency
         of this Indenture or of the Securities. Neither the Trustee nor any
         Authenticating Agent shall be accountable for the use or application by
         the Company of the Securities or the proceeds thereof.

                SECTION 6.5.   May Hold Securities.

                The Trustee, any Authenticating Agent, any Paying Agent, any
         Securities Registrar or any other agent of the Company, in its
         individual or any other capacity, may become the owner or pledgee of
         Securities and, subject to Sections 6.8 and 6.13, may otherwise deal
         with the Company with the same rights it would have if it were not
         Trustee, Authenticating Agent, Paying Agent, Securities Registrar or
         such other agent.

                SECTION 6.6.   Money Held in Trust.

                Money held by the Trustee in trust hereunder 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 money received
         by it hereunder except as otherwise agreed with the Company.

                SECTION 6.7.   Compensation and Reimbursement.

                (a) The Company agrees to pay to the Trustee from time to time
         reasonable compensation for all services rendered by it hereunder in
         such amounts as the Company and the Trustee shall agree from time to
         time (which compensation shall not be limited
<PAGE>   68

                                       - 62 -


         by any provision of law in regard to the compensation of a trustee
         of an express trust).

                (b) The Company agrees to reimburse the Trustee upon its request
         for all reasonable expenses, disbursements and advances incurred or
         made by the Trustee in accordance with any provision of this Indenture
         (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 its negligence or bad
         faith.

                (c) Since the Issuer Trust is being formed solely to facilitate
         an investment in the Capital Securities, the Company, as Holder of the
         Common Securities, hereby covenants to pay all debts and obligations
         (other than with respect to the Capital Securities and the Common
         Securities) and all reasonable costs and expenses of the Issuer Trust
         (including without limitation all costs and expenses relating to the
         organization of the Issuer Trust, the fees and expenses of the trustees
         and all reasonable costs and expenses relating to the operation of the
         Issuer Trust) and to pay any and all taxes, duties, assessments or
         governmental charges of whatever nature (other than withholding taxes)
         imposed on the Issuer Trust by the United States, or any taxing
         authority, so that the net amounts received and retained by the Issuer
         Trust and the Property Trustee after paying such expenses will be equal
         to the amounts the Issuer Trust and the Property Trustee would have
         received had no such costs or expenses been incurred by or imposed on
         the Issuer Trust. The foregoing obligations of the Company are for the
         benefit of, and shall be enforceable by, any person to whom any such
         debts, obligations, costs, expenses and taxes are owed (each, a
         "Creditor") whether or not such Creditor has received notice thereof.
         Any such Creditor may enforce such obligations directly against the
         Company, and the Company irrevocably waives any right or remedy to
         require that any such Creditor take any action against the Issuer Trust
         or any other person before proceeding against the Company. The Company
         shall execute such additional agreements as may be necessary or
         desirable to give full effect to the foregoing.

                (d) The Company shall indemnify the Trustee for, and hold it
         harmless against, any loss, liability or expense (including the
         reasonable compensation and the expenses and disbursements of its
         agents and counsel) incurred without negligence or bad faith, arising
         out of or in connection with the acceptance or administration of this
         trust or the performance of its duties hereunder, including the
         reasonable 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. This indemnification shall survive the
         termination of this Indenture or the resignation or removal of the
         Trustee.
<PAGE>   69

                                       - 63 -


                When the Trustee incurs expenses or renders services after an
         Event of Default specified in Section 5.1(4) occurs, the expenses and
         the compensation for the services are intended to constitute expenses
         of administration under the Bankruptcy Reform Act of 1978 or any
         successor statute.

                SECTION 6.8.   Disqualification; Conflicting Interests.

                The Trustee for the Securities of any series issued hereunder
         shall be subject to the provisions of Section 310(b) of the Trust
         Indenture Act. Nothing herein shall prevent the Trustee from filing
         with the Commission the application referred to in the second to last
         paragraph of said Section 310(b).

                SECTION 6.9.   Corporate Trustee Required; Eligibility.

                There shall at all times be a Trustee hereunder which shall be:

                (a) an entity organized and doing business under the laws of the
         United States of America or of any state or territory thereof or of the
         District of Columbia, authorized under such laws to exercise corporate
         trust powers and subject to supervision or examination by Federal,
         state, territorial or District of Columbia authority, or

                (b) an entity or other Person organized and doing business under
         the laws of a foreign government that is permitted to act as Trustee
         pursuant to a rule, regulation or order of the Commission, authorized
         under such laws to exercise corporate trust powers, and subject to
         supervision or examination by authority of such foreign government or a
         political subdivision thereof substantially equivalent to supervision

                SECTION 6.10.  Resignation and Removal; Appointment of
                               Successor.

                (a) No resignation or removal of the Trustee and no appointment
         of a successor Trustee pursuant to this Article shall become effective
         until the acceptance of appointment by the successor Trustee under
         Section 6.11.

                (b) The Trustee may resign at any time with respect to the
         Securities of one or more series by giving written notice thereof to
         the Company. If an instrument of acceptance by a successor Trustee
         shall not have been delivered to the Trustee within 30 days after the
         giving 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 the Securities of such series.

                (c) The Trustee may be removed at any time with respect to the
         Securities of any series by Act of the Holders of a majority in
         aggregate principal amount of the Outstanding Securities of such
         series, delivered to the Trustee and to the Company.

                (d)  If at any time:

                     (1) the Trustee shall fail to comply with Section 6.8 after
                written request therefor by the Company or by any Holder who has
                been a bona fide Holder of a Security for at least six months,
                or

                     (2) the Trustee shall cease to be eligible under Section
                6.9 and shall fail to resign after written request therefor by
                the Company or by any such Holder, or

                     (3) the Trustee shall become incapable of acting or shall
                be adjudged a bankrupt or insolvent or a receiver of the Trustee
                or of its property shall be appointed 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, (i) the Company, acting pursuant to the
         authority of a Board Resolution, may remove the Trustee with respect to
         the Securities of all series issued hereunder, or (ii) subject to
         Section 5.14, any Holder who has been a bona fide Holder of a Security
         for at least six months may, on behalf of such Holder and all others
         similarly situated, petition any court of competent jurisdiction for
         the removal of the Trustee with respect to the Securities of all series
         issued hereunder and the appointment of a successor Trustee or
         Trustees.

                (e) If the Trustee shall resign, be removed or become incapable
         of acting, or if a vacancy shall occur in the office of Trustee for any
         cause with respect to the Securities of one or more series, the
         Company, by a Board Resolution, shall promptly appoint a successor
         Trustee with respect to the Securities of that or those series. If,
         within one year after such resignation, removal or incapability, or the
         occurrence of such vacancy, a successor Trustee with respect to the
         Securities of any series shall be appointed by Act of the Holders of a
         majority in aggregate principal amount of the Outstanding Securities of
         such series delivered to the Company and the retiring Trustee, the
         successor Trustee so appointed shall, forthwith upon its acceptance of
         such appointment, become the successor Trustee with respect to the
         Securities of such series and supersede the successor Trustee appointed
         by the Company. If no successor Trustee with respect to the Securities
         of any series shall have been so appointed by the Company or the
         Holders and accepted appointment in the manner hereinafter provided,
         any Holder who has been a bona fide Holder of a Security of such series
         for at least six months may, subject to Section 5.14, on behalf of such
         Holder and all others similarly situated, petition any court of
         competent jurisdiction for the appointment of a successor Trustee with
         respect to the Securities of such series.

                (f) The Company shall give notice of each resignation and each
         removal of the Trustee with respect to the Securities of any series and
         each appointment of a successor Trustee with respect to the Securities
         of any series by mailing written notice of such event by first-class
         mail, postage prepaid, to the Holders of Securities of such series as
         their names and addresses appear in the Securities Register. Each
         notice shall include the name of the successor Trustee with respect to
         the Securities of such series and the address of its Corporate Trust
         Office.

                SECTION 6.11.  Acceptance of Appointment by Successor.

                (a) In case of the appointment hereunder of a successor Trustee
         with respect to all Securities, every such 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.

                (b) In case of the appointment hereunder of a successor Trustee
         with respect to the Securities of one or more (but not all) series, the
         Company, the retiring Trustee and each successor Trustee with respect
         to the Securities of one or more series shall execute and deliver an
         indenture supplemental hereto wherein each successor Trustee shall
         accept such appointment and which (1) shall contain such provisions as
         shall be necessary or desirable to transfer and confirm to, and to vest
         in, each successor Trustee all the rights, powers, trusts and duties of
         the retiring Trustee with respect to the Securities of that or those
         series to which the appointment of such successor Trustee relates, (2)
         if the retiring Trustee is not retiring with respect to all Securities,
         shall contain such provisions as shall be deemed necessary or desirable
         to confirm that all the rights, powers, trusts and duties of the
         retiring Trustee with respect to the Securities of that or those series
         as to which the retiring Trustee is not retiring shall continue to be
         vested in the retiring Trustee, and (3) shall add to or change any of
         the provisions of this Indenture as shall be necessary to provide for
         or facilitate the administration of the trusts hereunder by more than
         one Trustee, it being understood that nothing herein or in such
         supplemental indenture shall constitute such Trustees or co-trustees of
         the same trust and that each such Trustee shall be trustee of a trust
         or trusts hereunder separate and apart from any trust or trusts
         hereunder administered by any other such Trustee; and upon the
         execution and delivery of such supplemental indenture the resignation
         or removal of the retiring Trustee shall become effective to the extent
         provided therein and each removal of the retiring Trustee, without any
         further act, deed or conveyance, shall become vested with all the
         rights, powers, trusts, and duties of the retiring Trustee with respect
         to the Securities of that or those series to which the appointment of
         such successor Trustee relates; but, on request of the Company or any
         successor Trustee, such retiring Trustee shall duly assign, transfer
         and deliver to such successor Trustee all property and money held by
         such retiring Trustee hereunder with respect to the Securities of that
         or those series to which the appointment of such successor Trustee
         relates.

                (c) Upon request of any such successor Trustee, the Company
         shall execute any and all instruments for more fully and certainly
         vesting in and confirming to such successor Trustee all rights, powers
         and trusts referred to in paragraph (a) or (b) of this Section, as the
         case may be.

                (d) 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.

                SECTION 6.12.  Merger, Conversion, Consolidation or
                               Succession to Business.

                Any entity into which the Trustee may be merged or converted or
         with which it may be consolidated, or any entity resulting from any
         merger, conversion or consolidation to which the Trustee shall be a
         party, or any entity succeeding to all or substantially all of the
         corporate trust business of the Trustee, shall be the successor of the
         Trustee hereunder, provided such entity shall be otherwise qualified
         and eligible under this Article, without the execution or filing of any
         paper or any further act on the part of any of the parties hereto. In
         case any Securities shall have been authenticated, but not delivered,
         by the Trustee then in office, any successor by merger, conversion or
         consolidation to such authenticating Trustee may adopt such
         authentication and deliver the Securities so authenticated, and in case
         any Securities shall not have been authenticated, any successor to the
         Trustee may authenticate such Securities either in the name of any
         predecessor Trustee or in the name of such successor Trustee, and in
         all cases the certificate of authentication shall have the full force
         which it is provided anywhere in the Securities or in this Indenture
         that the certificate of the Trustee shall have.

                SECTION 6.13.  Preferential Collection of Claims Against
                               Company.

                If and when the Trustee shall be or become a creditor of the
         Company (or any other obligor upon the Securities), the Trustee shall
         be subject to the provisions of the Trust Indenture Act regarding the
         collection of claims against the Company (or any such other obligor).

                SECTION 6.14.  Appointment of Authenticating Agent.

                The Trustee may appoint an Authenticating Agent or Agents with
         respect to one or more series of Securities, which shall be authorized
         to act on behalf of the Trustee to authenticate Securities of such
         series issued upon original issue and upon exchange, registration of
         transfer or partial redemption thereof or pursuant to Section 3.6, and
         Securities 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. Wherever reference is made in
         this Indenture to the authentication and delivery of Securities by the
         Trustee or the Trustee's certificate of authentication, such reference
         shall be deemed to include authentication and delivery on behalf of the
         Trustee by an Authenticating Agent. Each Authenticating Agent shall be
         acceptable to the Company and shall at all times be an entity organized
         and doing business under the laws of the United States of America, or
         of any state or territory thereof or of the

         District of Columbia, authorized under such laws to act as
         Authenticating Agent, having a combined capital and surplus of not less
         than $50,000,000 and subject to supervision or examination by Federal
         or state authority. If such Authenticating Agent publishes reports of
         condition at least annually, pursuant to law or to the requirements of
         said supervising or examining authority, then for the purposes of this
         Section the combined capital and surplus of such Authenticating Agent
         shall be deemed to be its combined capital and surplus as set forth in
         its most recent report of condition so published. If at any time an
         Authenticating Agent shall cease to be eligible in accordance with the
         provisions of this Section, such Authenticating Agent shall resign
         immediately in the manner and with the effect specified in this
         Section.

                Any entity into which an Authenticating Agent may be merged or
         converted or with which it may be consolidated, or any entity resulting
         from any merger, conversion or consolidation to which such
         Authenticating Agent shall be a party, or any entity succeeding to all
         or substantially all of the corporate trust business of an
         Authenticating Agent shall be the successor Authenticating Agent
         hereunder, provided such entity shall be otherwise eligible under this
         Section, without the execution or filing of any paper or any further
         act on the part of the Trustee or the Authenticating Agent.

                An Authenticating Agent may resign at any time by giving written
         notice thereof to the Trustee and to the Company. The Trustee may at
         any time terminate the agency of an Authenticating Agent by giving
         written notice thereof to such Authenticating Agent and to the Company.
         Upon receiving such a notice of resignation or upon such a termination,
         or in case at any time such Authenticating Agent shall cease to be
         eligible in accordance with the provisions of this Section, the Trustee
         may appoint a successor Authenticating Agent, which shall be acceptable
         to the Company and shall give notice of such appointment in the manner
         provided in Section 1.6 to all Holders of Securities of the series with
         respect to which such Authenticating Agent will serve. Any successor
         Authenticating Agent upon acceptance hereunder shall become vested with
         all the rights, powers and duties of its predecessor hereunder, with
         like effect as if originally named as an Authenticating Agent. No
         successor Authenticating Agent shall be appointed unless eligible under
         the provision of this Section.

                The Company agrees to pay to each Authenticating Agent from time
         to time reasonable compensation for its services under this Section,
         and the Trustee shall be entitled to be reimbursed for such payment,
         subject to the provisions of Section 6.7.

                If an appointment with respect to one or more series is made
         pursuant to this Section, the Securities of such series may

         authentication, an alternative certificate of authentication in the

                SECTION 8.1.   Company May Consolidate, Etc., Only on
                               Certain Terms.

                The Company shall not consolidate with or merge into any other
         Person or convey, transfer or lease its properties and assets

         consolidate with or merge into the Company or convey, transfer or lease
         its properties and assets substantially as an entirety to the Company,
         unless:

                     (1) If the Company shall consolidate with or merge into
                another Person or convey, transfer or lease its properties and
                assets substantially as an entirety to any Person, the entity
                formed by such consolidation or into which the Company is merged
                or the Person that acquires by conveyance or transfer, or that

                the laws of the United States of America or any state thereof or
                the District of Columbia and shall expressly assume, by an

                observed;

                          (2) immediately after giving effect to such
                transaction, no Event of Default, and no event that, after
                notice or lapse of time, or both, would constitute an Event of
                Default, shall have occurred and be continuing; and

                          (3) the Company has delivered to the Trustee an
                Officers' Certificate and an Opinion of Counsel, each stating
                that such consolidation, merger, conveyance, transfer or lease
                and any such supplemental indenture comply with this Article and
                that all conditions precedent herein provided for relating to
                such transaction have been complied with and, in the case of a
                transaction subject to this Section 8.1 but not requiring a
                supplemental indenture under paragraph (1) of this Section 8.1,
                an Officer's Certificate or Opinion of Counsel to the effect
                that the surviving, resulting or successor entity is legally
                bound by the Indenture and the Securities; and the Trustee,
                subject to Section 6.1, may rely upon such Officers'
                Certificates and Opinions of Counsel as conclusive evidence that
                such transaction complies with this Section 8.1.

                SECTION 8.2.   Successor Company Substituted.

                Upon any consolidation or merger by the Company with or into any
         other Person, or any conveyance, transfer or lease by the Company of
         its properties and assets substantially as an entirety to any Person in
         accordance with Section 8.1, the successor entity formed by such
         consolidation or into which the Company is merged or to which such
         conveyance, transfer or lease is made shall succeed to, and be
         substituted for, and may exercise every right and power of, the Company
         under this Indenture with the same effect as if such successor Person
         had been named as the Company herein; and in the event of any such
         conveyance, transfer or lease the Company shall be discharged from all
         obligations and covenants under the Indenture and the Securities.

                Such successor Person may cause to be executed, and may issue
         either in its own name or in the name of the Company, any or all of the
         Securities issuable hereunder that theretofore shall not have been
         signed by the Company and delivered to the Trustee; and, upon the order
         of such successor Person instead of the Company and subject to all the
         terms, conditions and limitations in this Indenture prescribed, the
         Trustee shall authenticate and shall deliver any Securities that
         previously shall have been signed and delivered by the officers of the
         Company to the Trustee for authentication pursuant to such provisions
         and any Securities that such successor Person thereafter shall cause to
         be executed and delivered to the Trustee on its behalf for the purpose
         pursuant to such provisions. All the Securities so issued shall in all
         respects have the same legal rank and benefit under this Indenture as
         the Securities theretofore or thereafter issued in accordance with the
         terms of this Indenture.

                In case of any such consolidation, merger, sale, conveyance or
         lease, such changes in phraseology and form may be made in the
         Securities thereafter to be issued as may be appropriate.

         provision herein that may be defective or inconsistent with any other
         provision herein, or to make any other provisions with respect to
         matters or questions arising under this Indenture, provided that such
         action pursuant to this clause (8) shall not adversely affect the
         interest of the Holders of Securities of any series in any material
         respect or, in the case of the Securities of a series issued to an
         Issuer Trust and for so long as any of the corresponding series of
         Capital Securities issued by such Issuer Trust shall remain
         outstanding, the holders of such Capital Securities; or

                (9) to evidence and provide for the acceptance of appointment
         hereunder by a successor Trustee with respect to the Securities of one

                               Holders.

                With the consent of the Holders of not less than a majority in
         aggregate principal amount of the Outstanding Securities of each series
         affected by such supplemental indenture, by Act of said Holders
         delivered to the Company and the Trustee, the Company, when authorized

         of Securities of such series under this Indenture; provided, however,
         that no such supplemental indenture shall, without the consent of the
         Holder of each Outstanding Security of each series affected thereby,

                     (2) reduce the percentage in aggregate principal amount of
                the Outstanding Securities of any series, the consent of whose
                Holders is required for any such supplemental indenture, or the

                defaults hereunder and their consequences) provided for in this
                Indenture, or

                cannot be modified or waived without the consent of the Holder
                of each Security affected thereby;

                provided, further, that, in the case of the Securities of a
                series issued to an Issuer Trust, so long as any of the
                corresponding series of Capital Securities issued by such Issuer
                Trust remains outstanding, (i) no such amendment shall be made
                that adversely affects the holders of such Capital Securities in
                any material respect, and no termination of this Indenture shall
                occur, and no waiver of any Event of Default or compliance with
                any covenant under this Indenture shall be effective, without
                the prior consent of the holders of at least a majority of the
                aggregate Liquidation Amount (as defined in the related Trust
                Agreement) of such Capital Securities then outstanding unless
                and until the principal of (and premium, if any, on) the
                Securities of such series and all accrued and (subject to

                Trust provided therein without the prior consent of the holders
                of each such Capital Security then outstanding unless and until

                such series and all accrued and (subject to Section 3.8) unpaid
                interest (including any Additional Interest) thereon have been
                paid in full.

                A supplemental indenture that changes or eliminates any covenant
         or other provision of this Indenture that has expressly been included
         solely for the benefit of one or more particular series of Securities
         or any corresponding series of Capital Securities of an Issuer Trust
         that holds the Securities of any series, or that modifies the rights of
         the Holders of Securities of such series or holders of such Capital
         Securities of such corresponding series with respect to such covenant
         or other

                                       - 76 -


         provision, shall be deemed not to affect the rights under this
         Indenture of the Holders of Securities of any other series or holders
         of Capital Securities of any other such corresponding series.

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

                SECTION 9.3.   Execution of Supplemental Indentures.

                In executing or accepting the additional trusts created by any
         supplemental indenture permitted by this Article or the modifications
         thereby of the trusts created by this Indenture, the Trustee shall be
         entitled to receive, and (subject to Section 6.1) shall be fully
         protected in relying upon, an Officers' Certificate and an Opinion of
         Counsel stating that the execution of such supplemental indenture is
         authorized or permitted by this Indenture, and that all conditions
         precedent herein provided for relating to such action have been
         complied with. The Trustee may, but 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.

                SECTION 9.4.   Effect of Supplemental Indentures.

                Upon the execution of any supplemental indenture under this
         Article, this Indenture shall be modified in accordance therewith, and
         such supplemental indenture shall form a part of this Indenture for all
         purposes; and every Holder of Securities theretofore or thereafter
         authenticated and delivered hereunder shall be bound thereby.

                SECTION 9.5.   Conformity with Trust Indenture Act.

                Every supplemental indenture executed pursuant to this Article
         shall conform to the requirements of the Trust Indenture Act as then in
         effect.

                SECTION 9.6.   Reference in Securities to Supplemental
                               Indentures.

                Securities authenticated and delivered after the execution of
         any supplemental indenture pursuant to this Article may, and shall if
         required by the Company, bear a notation in form approved by the
         Company as to any matter provided for in such supplemental indenture.
         If the Company shall so determine, new Securities of any series so
         modified as to conform, in the opinion of the Company, to any such
         supplemental indenture may be prepared and

         executed by the Company and authenticated and delivered by the Trustee
         in exchange for Outstanding Securities of such series.


                                    ARTICLE X
                                    COVENANTS

                SECTION 10.1.  Payment of Principal, Premium and Interest.

                The Company covenants and agrees for the benefit of each series
         of Securities that it will duly and punctually pay the principal of
         (and premium, if any) and interest (including any Additional Interest)
         on the Securities of that series in accordance with the terms of such
         Securities and this Indenture.

                SECTION 10.2.  Maintenance of Office or Agency.

                The Company will maintain in each Place of Payment for any
         series of Securities an office or agency where Securities of that
         series may be presented or surrendered for payment, where Securities of
         that series may be surrendered for registration of transfer or exchange
         and where notices and demands to or upon the Company in respect of the
         Securities of that series and this Indenture may be served. The Company
         initially appoints the Trustee, acting through its Corporate Trust
         Office, as its agent for said purposes. The Company will give prompt
         written notice to the Trustee of any change in the location of any such
         office or agency. If at any time the Company shall fail to maintain
         such office or agency or shall fail to furnish the Trustee with the
         address thereof, such presentations, surrenders, 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, surrenders, notices and demands.

                The Company may also from time to time designate one or more
         other offices or agencies where the Securities may be presented or
         surrendered for any or all of such purposes, and may from time to time
         rescind such designations; provided, however, that no such designation
         or rescission shall in any manner relieve the Company of its obligation
         to maintain an office or agency in each Place of Payment for Securities
         of any series for such purposes. The Company will give prompt written
         notice to the Trustee of any such designation and any change in the
         location of any such office or agency.

                SECTION 10.3.  Money for Security Payments to be Held in
                               Trust.

                If the Company shall at any time act as its own Paying Agent
         with respect to any series of Securities, it will, on or before each
         due date of the principal of (and premium, if any) or interest
         (including Additional Interest) on any of the Securities of such
         series, segregate and hold in trust for the benefit of the Persons
         entitled thereto a sum sufficient to pay the principal (and premium, if
         any) or interest (including Additional Interest) so becoming due until
         such sums shall be paid to such Persons or otherwise disposed of as
         herein provided, and will promptly notify the Trustee of its failure so
         to act.

                Whenever the Company shall have one or more Paying Agents, it
         will, prior to 10:00 a.m., New York City time, on each due date of the
         principal of (or premium, if any) or interest, including Additional
         Interest on any Securities, deposit with a Paying Agent a sum
         sufficient to pay the principal (and premium, if any) or interest,
         including Additional Interest so becoming due, such sum to be held in
         trust for the benefit of the Persons entitled to such principal (and
         premium, if any) or interest, including Additional Interest, and
         (unless such Paying Agent is the Trustee) the Company will promptly
         notify the Trustee of its failure so to act.

                The Company will cause each Paying Agent other than the Trustee
         to execute and deliver to the Trustee an instrument in which such
         Paying Agent shall agree with the Trustee, subject to the provisions of
         this Section, that such Paying Agent will:

                (1) hold all sums held by it for the payment of the principal of
         (and premium, if any, or interest (including Additional Interest) on
         the Securities of a series in trust for the benefit of the Persons
         entitled thereto until such sums shall be paid to such Persons or
         otherwise disposed of as herein provided;

                (2) give the Trustee notice of any default by the Company (or
         any other obligor upon such Securities) in the making of any payment of
         principal (and premium, if any) or interest (or Additional Interest) in
         respect of any Security of any Series;

                (3) at any time during the continuance of any default with
         respect to a series of Securities, upon the written request of the
         Trustee, forthwith pay to the Trustee all sums so held in trust by such
         Paying Agent with respect to such series; and
<PAGE>   85

                                       - 79 -


                (4) comply with the provisions of the Trust Indenture Act
         applicable to it as a Paying Agent.

                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 by Company Order 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 trusts as those upon which such
         sums were held by the Company 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.

                Any money deposited with the Trustee or any Paying Agent, or
         then held by the Company in trust for the payment of the principal of
         (and premium, if any) or interest (including Additional Interest) on
         any Security and remaining unclaimed for two years after such principal
         (and premium, if any) or interest (including Additional Interest) has
         become due and payable shall (unless otherwise required by mandatory
         provision of applicable escheat or abandoned or unclaimed property law)
         be paid on Company Request to the Company, or (if then held by the
         Company) shall (unless otherwise required by mandatory provision of
         applicable escheat or abandoned or unclaimed property law) be
         discharged from such trust; and the Holder of such Security shall
         thereafter, as an unsecured general creditor, look only to the Company
         for payment thereof, and all liability of the Trustee or such Paying
         Agent with respect to such trust money, and all liability of the
         Company as trustee thereof, shall thereupon cease; provided, however,
         that the Trustee or such Paying Agent, before being required to make
         any such repayment, may at the expense of the Company cause to be
         published once, in a newspaper published in the English language,
         customarily published on each Business Day and of general circulation
         in the Borough of Manhattan, the City of New York, notice that such
         money remains unclaimed and that, after a date specified therein, which
         shall not be less than 30 days from the date of such publication, any
         unclaimed balance of such money then remaining will be repaid to the
         Company.

                SECTION 10.4.  Statement as to Compliance.

                The Company shall deliver to the Trustee, within 120 days after
         the end of each fiscal year of the Company ending after the date
         hereof, an Officers' Certificate covering the preceding calendar year,
         stating whether or not to the best knowledge of the signers thereof of
         the Company is in default in the performance, observance or fulfillment
         of or compliance with any of the terms, provisions, covenants and
         conditions of this Indenture, and if the Company shall be in default,
         specifying all such defaults and the nature and status thereof of which
         they may have knowledge. For the purpose of this Section 10.4,
         compliance shall be determined
<PAGE>   86

                                       - 80 -


         without regard to any grace period or requirement of notice provided
         pursuant to the terms of this Indenture.

                SECTION 10.5.  Waiver of Certain Covenants.

                Subject to the rights of holders of Capital Securities specified
         in Section 9.2, if any, the Company may omit in any particular instance
         to comply with any covenant or condition provided pursuant to Section
         3.1, 9.1(3) or 9.1(4) with respect to the Securities of any series, if
         before or after the time for such compliance the Holders of at least a
         majority in aggregate principal amount of the Outstanding Securities of
         such series shall, by Act of such Holders, either waive such compliance
         in such instance or generally waive compliance with such covenant or
         condition, but no such waiver shall extend to or affect such covenant
         or condition except to the extent so expressly waived, and, until such
         waiver shall become effective, the obligations of the Company in
         respect of any such covenant or condition shall remain in full force
         and effect.

                SECTION 10.6.  Additional Sums.

                In the case of the Securities of a series initially issued to an
         Issuer Trust, so long as no Event of Default has occurred and is
         continuing and except as otherwise specified as contemplated by Section
         2.1 or Section 3.1, if (i) an Issuer Trust is the Holder of all of the
         Outstanding Securities of such series, and (ii) a Tax Event described
         in clause (i) or (iii) of the definition of "Tax Event" in Section 1.1
         hereof has occurred and is continuing in respect of such Issuer Trust,
         the Company shall pay to such Issuer Trust (and its permitted
         successors or assigns under the related Trust Agreement) for so long as
         such Issuer Trust (or its permitted successor or assignee) is the
         registered holder of the Outstanding Securities of such series, such
         additional sums as may be necessary in order that the amount of
         Distributions (including any Additional Amounts (as defined in such
         Trust Agreement)) then due and payable by such Issuer Trust on the
         related Capital Securities and Common Securities that at any time
         remain outstanding in accordance with the terms thereof shall not be
         reduced as a result of such Additional Taxes (the "Additional Sums").
         Whenever in this Indenture or the Securities there is a reference in
         any context to the payment of principal of or interest on the
         Securities, such mention shall be deemed to include mention of the
         payments of the Additional Sums provided for in this paragraph to the
         extent that, in such context, Additional Sums are, were or would be
         payable in respect thereof pursuant to the provisions of this paragraph
         and express mention of the payment of Additional Sums (if applicable)
         in any provisions hereof shall not be construed as excluding Additional
         Sums in those provisions hereof where such express mention is not made;
         provided, however, that the deferral of the payment of
<PAGE>   87

                                       - 81 -


         interest pursuant to Section 3.12 or the Securities shall not defer the
         payment of any Additional Sums that may be due and payable.

                SECTION 10.7.  Additional Covenants.

                The Company covenants and agrees with each Holder of Securities
         of each series that it shall not (x) declare or pay any dividends or
         distributions on, or redeem purchase, acquire or make a liquidation
         payment with respect to, any shares of the Company's capital stock, or
         (y) make any payment of principal of or interest or premium, if any, on
         or repay, repurchase or redeem any debt securities of the Company that
         rank pari passu in all respects with or junior in interest to the
         Securities of such series (other than (a) repurchases, redemptions or
         other acquisitions of shares of capital stock of the Company in
         connection with any employment contract, benefit plan or other similar
         arrangement with or for the benefit of any one or more employees,
         officers, directors or consultants, in connection with a dividend
         reinvestment or stockholder stock purchase plan or in connection with
         the issuance of capital stock of the Company (or securities convertible
         into or exercisable for such capital stock) as consideration in an
         acquisition transaction entered into prior to the applicable Extension
         Period or other event referred to below, (b) as a result of an exchange
         or conversion of any class or series of the Company's capital stock (or
         any capital stock of a Subsidiary of the Company) for any class or
         series of the Company's capital stock or of any class or series of the
         Company's indebtedness for any class or series of the Company's capital
         stock, (c) the purchase of fractional interests in shares of the
         Company's capital stock pursuant to the conversion or exchange
         provisions of such capital stock or the security being converted or
         exchanged, (d) any declaration of a dividend in connection with any
         Rights Plan, or the issuance of rights, stock or other property under
         any Rights Plan, or the redemption or repurchase of rights pursuant
         thereto, or (e) any dividend in the form of stock, warrants, options or
         other rights where the dividend stock or the stock issuable upon
         exercise of such warrants, options or other rights is the same stock as
         that on which the dividend is being paid or ranks pari passu with or
         junior to such stock) if at such time (i) there shall have occurred any
         event (A) of which the Company has actual knowledge that with the
         giving of notice or the lapse of time, or both, would constitute an
         Event of Default with respect to the Securities of such series, and (B)
         which the Company shall not have taken reasonable steps to cure, (ii)
         if the Securities of such series are held by an Issuer Trust, the
         Company shall be in default with respect to its payment of any
         obligations under the Guarantee relating to the Capital Securities
         issued by such Issuer Trust, or (iii) the Company shall have given
         notice of its election to begin an Extension Period with respect to the
         Securities of such series as provided herein and shall not have
<PAGE>   88

                                       - 82 -


         rescinded such notice, or such Extension Period, or any extension
         thereof, shall be continuing.

                The Company also covenants with each Holder of Securities of a
         series issued to an Issuer Trust (i) to hold, directly or indirectly,
         100% of the Common Securities of such Issuer Trust, provided that any
         permitted successor of the Company as provided under Section 8.2 may
         succeed to the Company's ownership of such Common Securities, (ii) as
         holder of such Common Securities, not to voluntarily terminate, windup
         or liquidate such Issuer Trust, other than (a) in connection with a
         distribution of the Securities of such series to the holders of the
         related Capital Securities in liquidation of such Issuer Trust, or (b)
         in connection with certain mergers, consolidations or amalgamations
         permitted by the related Trust Agreement, and (iii) to use its
         reasonable efforts, consistent with the terms and provisions of such
         Trust Agreement, to cause such Issuer Trust to continue not to be
         taxable as a corporation for United States Federal income tax purposes.

                SECTION 10.8.  Original Issue Discount.

                On or before December 15 of each year during which any
         Securities are outstanding, the Company shall furnish to each Paying
         Agent such information as may be reasonably requested by each Paying
         Agent in order that each Paying Agent may prepare the information which
         it is required to report for such year on Internal Revenue Service
         Forms 1096 and 1099 pursuant to Section 6049 of the Internal Revenue
         Code of 1986, as amended. Such information shall include the amount of
         original issue discount includible in income for each authorized
         minimum denomination of principal amount at Stated Maturity of
         outstanding Securities during such year.


                                   ARTICLE XI
                            REDEMPTION OF SECURITIES

                SECTION 11.1.  Applicability of This Article.

                Redemption of Securities of any series as permitted or required
         by any form of Security issued pursuant to this Indenture shall be made
         in accordance with such form of Security and this Article; provided,
         however, that, if any provision of any such form of Security shall
         conflict with any provision of this Article, the provision of such form
         of Security shall govern.

                SECTION 11.2.  Election to Redeem; Notice to Trustee.

                The election of the Company to redeem any Securities shall be
         evidenced by or pursuant to a Board Resolution. In case of any
         redemption at the election of the Company, the Company shall, not
<PAGE>   89

                                       - 83 -


         less than 30 nor more than 60 days prior to the Redemption Date (unless
         a shorter notice shall be satisfactory to the Trustee), notify the
         Trustee and, in the case of Securities of a series held by an Issuer
         Trust, the Property Trustee under the related Trust Agreement, of such
         date and of the principal amount of Securities of the applicable series
         to be redeemed and provide the additional information required to be
         included in the notice or notices contemplated by Section 11.4;
         provided that, in the case of any series of Securities initially issued
         to an Issuer Trust, for so long as such Securities are held by such
         Issuer Trust, such notice shall be given not less than 45 nor more than
         75 days prior to such Redemption Date (unless a shorter notice shall be
         satisfactory to the Property Trustee under the related Trust
         Agreement). In the case of any redemption of Securities prior to the
         expiration of any restriction on such redemption provided in the terms
         of such Securities, the Company shall furnish the Trustee with an
         Officers' Certificate and an Opinion of Counsel evidencing compliance
         with such restriction.

                SECTION 11.3.  Selection of Securities to be Redeemed.

                If less than all the Securities of any series are to be
         redeemed, the particular Securities to be redeemed shall be selected
         not more than 60 days prior to the Redemption Date by the Trustee, from
         the Outstanding Securities of such series not previously called for
         redemption, by such method as the Trustee shall deem fair and
         appropriate and which may provide for the selection for redemption of a
         portion of the principal amount of any Security of such series,
         provided that the unredeemed portion of the principal amount of any
         Security shall be in an authorized denomination (which shall not be
         less than the minimum authorized denomination) for such Security.

                The Trustee shall promptly notify the Company in writing of the
         Securities selected for partial redemption and the principal amount
         thereof to be redeemed. For all purposes of this Indenture, unless the
         context otherwise requires, all provisions relating to the redemption
         of Securities shall relate, in the case of any Security redeemed or to
         be redeemed only in part, to the portion of the principal amount of
         such Security that has been or is to be redeemed.

                SECTION 11.4.  Notice of Redemption.

                Notice of redemption shall be given by first-class mail, postage
         prepaid, mailed not later than the thirtieth day, and not earlier than
         the sixtieth day, prior to the Redemption Date, to each Holder of
         Securities to be redeemed, at the address of such Holder as it appears
         in the Securities Register.
<PAGE>   90

                                       - 84 -


                With respect to Securities of such series to be redeemed, each
         notice of redemption shall state:

                (a)  the Redemption Date;

                (b) the Redemption Price or, if the Redemption Price cannot be
         calculated prior to the time the notice is required to be sent, the
         estimate of the Redemption Price provided pursuant to the Indenture
         together with a statement that it is an estimate and that the actual
         Redemption Price will be calculated on the third Business Day prior to
         the Redemption Date (if such an estimate of the Redemption Price is
         given, a subsequent notice shall be given as set forth above setting
         forth the Redemption Price promptly following the calculation thereof);

                (c) if less than all Outstanding Securities of such particular
         series are to be redeemed, the identification (and, in the case of
         partial redemption, the respective principal amounts) of the particular
         Securities to be redeemed;

                (d) that, on the Redemption Date, the Redemption Price will
         become due and payable upon each such Security or portion thereof, and
         that interest thereon, if any, shall cease to accrue on and after said
         date;

                (e)  the place or places where such Securities are to be
         surrendered for payment of the Redemption Price;

                (f)  such other provisions as may be required in respect of
         the terms of a particular series of Securities; and

                (g)  that the redemption is for a sinking fund, if such is
         the case.

                Notice of redemption of Securities to be redeemed at the
         election of the Company shall be given by the Company or, at the
         Company's request, by the Trustee in the name and at the expense of the
         Company and shall be irrevocable. The notice, if mailed in the manner
         provided above, shall be conclusively presumed to have been duly given,
         whether or not the Holder receives such notice. In any case, a failure
         to give such notice by mail or any defect in the notice to the Holder
         of any Security designated for redemption as a whole or in part shall
         not affect the validity of the proceedings for the redemption of any
         other Security.

                SECTION 11.5.  Deposit of Redemption Price.

                Prior to 10:00 a.m., New York City time, on the Redemption Date
         specified in the notice of redemption given as provided in Section
         11.4, the Company will deposit with the Trustee or with one or more
         Paying Agents (or if the Company is acting as its own
<PAGE>   91

                                       - 85 -


         Paying Agent, the Company will segregate and hold in trust as provided
         in Section 10.3) an amount of money sufficient to pay the Redemption
         Price of, and any accrued interest (including Additional Interest) on,
         all the Securities (or portions thereof) that are to be redeemed on
         that date.

                SECTION 11.6.  Payment of Securities Called for Redemption.

                If any notice of redemption has been given as provided in
         Section 11.4, the Securities or portion of Securities with respect to
         which such notice has been given shall become due and payable on the
         date and at the place or places stated in such notice at the applicable
         Redemption Price, together with accrued interest (including any
         Additional Interest) to the Redemption Date. On presentation and
         surrender of such Securities at a Place of Payment in said notice
         specified, the said Securities or the specified portions thereof shall
         be paid and redeemed by the Company at the applicable Redemption Price,
         together with accrued interest (including any Additional Interest) to
         the Redemption Date; provided, however, that, unless otherwise
         specified as contemplated by Section 3.1, installments of interest
         (including Additional Interest) whose Stated Maturity is on or prior to
         the Redemption Date will be payable to the Holders of such Securities,
         or one or more Predecessor Securities, registered as such at the close
         of business on the relevant record dates according to their terms and
         the provisions of Section 3.8.

                Upon presentation of any Security redeemed in part only, the
         Company shall execute and the Trustee shall authenticate and deliver to
         the Holder thereof, at the expense of the Company, a new Security or
         Securities of the same series, of authorized denominations, in
         aggregate principal amount equal to the unredeemed portion of the
         Security so presented and having the same Original Issue Date, Stated
         Maturity and terms.

                If any Security called for redemption shall not be so paid under
         surrender thereof for redemption, the principal of and premium, if any,
         on such Security shall, until paid, bear interest from the Redemption
         Date at the rate prescribed therefor in the Security.

                SECTION 11.7.  Right of Redemption of Securities Initially
                               Issued to an Issuer Trust.

                In the case of the Securities of a series initially issued to an
         Issuer Trust, except as otherwise specified as contemplated by Section
         3.1, the Company, at its option, may redeem such Securities (i) on or
         after the date specified in such Security, in whole at any time or in
         part from time to time, or (ii) upon the occurrence and during the
         continuation of a Tax Event, an Investment Company Event or a Capital
         Treatment Event, at any time
<PAGE>   92

                                       - 86 -


         within 90 days following the occurrence and during the continuation of
         such Tax Event, Investment Company Event or Capital Treatment Event, in
         whole (but not in part), in each case at a Redemption Price specified
         in such Security, together with accrued interest (including Additional
         Interest) to the Redemption Date.

                If less than all the Securities of any such series are to be
         redeemed, the aggregate principal amount of such Securities remaining
         Outstanding after giving effect to such redemption shall be sufficient
         to satisfy any provisions of the Trust Agreement related to the Issuer
         Trust to which such Securities were issued.


                                   ARTICLE XII
                                  SINKING FUNDS

                Except as may be provided in any supplemental or amended
         indenture, no sinking fund shall be established or maintained for the
         retirement of Securities of any series.

                SECTION 13.1.  Securities Subordinate to Senior
                               Indebtedness.

                The Company covenants and agrees, and each Holder of a Security,
         by its acceptance thereof, likewise covenants and agrees, that, to the
         extent and in the manner hereinafter set forth in this Article, the
         payment of the principal of (and premium, if any) and interest
         (including any Additional Interest) on each and all of the Securities
         of each and every series are hereby expressly made subordinate and
         subject in right of payment to the prior payment in full of all Senior
         Indebtedness.

                SECTION 13.2.  No Payment When Senior Indebtedness in
                               Default; Payment Over of Proceeds Upon
                                Dissolution, Etc.

                If the Company shall default in the payment of any principal of
         (or premium, if any) or interest on any Senior Indebtedness when the
         same becomes due and payable, whether at maturity or at a date fixed
         for prepayment or by declaration of acceleration or otherwise, then,
         upon written notice of such default to the Company by the holders of
         Senior Indebtedness or any trustee therefor, unless and until such
         default shall have been cured or waived or shall have ceased to exist,
         no direct or indirect payment (in cash, property, securities, by
         set-off or otherwise) shall be made or agreed to be made on account of
         the

                                       - 87 -


         principal of (or premium, if any) or interest (including Additional
         Interest) on any of the Securities, or in respect of any redemption,
         repayment, retirement, purchase or other acquisition of any of the
         Securities.

                In the event of (i) any insolvency, bankruptcy, receivership,
         liquidation, reorganization, readjustment, composition or other similar
         proceeding relating to the Company, its creditors or its property, (ii)
         any proceeding for the liquidation, dissolution or other winding up of
         the Company, voluntary or involuntary, whether or not involving
         insolvency or bankruptcy proceedings, (iii) any assignment by the
         Company for the benefit of creditors or (iv) any other marshalling of
         the assets of the Company (each such event, if any, herein sometimes
         referred to as a "Proceeding"), all Senior Indebtedness (including any
         interest thereon accruing after the commencement of any such
         proceedings) shall first be paid in full before any payment or
         distribution, whether in cash, securities or other property, shall be
         made to any Holder of any of the Securities on account thereof. Any
         payment or distribution, whether in cash, securities or other property
         (other than securities of the Company or any other entity provided for
         by a plan of reorganization or readjustment, the payment of which is
         subordinate, at least to the extent provided in these subordination
         provisions with respect to the indebtedness evidenced by the
         Securities, to the payment of all Senior Indebtedness at the time
         outstanding and to any securities issued in respect thereof under any
         such plan of reorganization or readjustment), which would otherwise
         (but for these subordination provisions) be payable or deliverable in
         respect of the Securities of any series shall be paid or delivered
         directly to the holders of Senior Indebtedness in accordance with the
         priorities then existing among such holders until all Senior
         Indebtedness (including any interest thereon accruing after the
         commencement of any Proceeding) shall have been paid in full.

                In the event of any Proceeding, after payment in full of all
         sums owing with respect to Senior Indebtedness, the Holders of the
         Securities, together with the holders of any obligations of the Company
         ranking on a parity with the Securities, shall be entitled to be paid
         from the remaining assets of the Company the amounts at the time due
         and owing on account of unpaid principal of (and premium, if any) and
         interest on the Securities and such other obligations before any
         payment or other distribution, whether in cash, property or otherwise,
         shall be made on account of any capital stock or any obligations of the
         Company ranking junior to the Securities, and such other obligations.
         If, notwithstanding the foregoing, any payment or distribution of any
         character or any security, whether in cash, securities or other
         property (other than securities of the Company or any other entity
         provided for by a plan of reorganization or readjustment the payment of
         which is subordinate, at least to the extent provided
<PAGE>   94

                                       - 88 -


         in these subordination provisions with respect to the indebtedness
         evidenced by the Securities, to the payment of all Senior Indebtedness
         at the time outstanding and to any securities issued in respect thereof
         under any plan of reorganization or readjustment), shall be received by
         the Trustee or any Holder in contravention of any of the terms hereof
         and before all Senior Indebtedness shall have been paid in full, such
         payment or distribution or security shall be received in trust for the
         benefit of, and shall be paid over or delivered and transferred to, the
         holders of the Senior Indebtedness at the time outstanding in
         accordance with the priorities then existing among such holders for
         application to the payment of all Senior Indebtedness remaining unpaid,
         to the extent necessary to pay all such Senior Indebtedness in full. In
         the event of the failure of the Trustee or any Holder to endorse or
         assign any such payment, distribution or security, each holder of
         Senior Indebtedness is hereby irrevocably authorized to endorse or
         assign the same.

                The Trustee and the Holders shall take such action (including,
         without limitation, the delivery of this Indenture to an agent for the
         holders of Senior Indebtedness or consent to the filing of a financing
         statement with respect hereto) as may, in the opinion of counsel
         designated by the holders of a majority in principal amount of the
         Senior Indebtedness at the time outstanding, be necessary or
         appropriate to assure the effectiveness of the subordination effected
         by these provisions.

                The provisions of this Section 13.2 shall not impair any rights,
         interests, remedies or powers of any secured creditor of the Company in
         respect of any security interest the creation of which is not
         prohibited by the provisions of this Indenture.

                The securing of any obligations of the Company, otherwise
         ranking on a parity with the Securities or ranking junior to the
         Securities shall not be deemed to prevent such obligations from
         constituting, respectively, obligations ranking on a parity with the
         Securities or ranking junior to the Securities.

                SECTION 13.3.  Payment Permitted If No Default.

                Nothing contained in this Article or elsewhere in this Indenture
         or in any of the Securities shall prevent (a) the Company, at any time,
         except during the pendency of the conditions described in the first
         paragraph of Section 13.2 or of any Proceeding referred to in Section
         13.2, from making payments at any time of principal of (and premium, if
         any) or interest (including Additional Interest) on the Securities, or
         (b) the application by the Trustee of any monies deposited with it
         hereunder to the payment of or on account of the principal of (and
         premium, if any) or interest (including any Additional Interest) on the
         Securities or the retention of such payment by the Holders,
<PAGE>   95

                                       - 89 -


         if, at the time of such application by the Trustee, it did not have
         knowledge that such payment would have been prohibited by the
         provisions of this Article.

                SECTION 13.4.  Subrogation to Rights of Holders of Senior
                               Indebtedness.

                Subject to the payment in full of all amounts due or to become
         due on all Senior Indebtedness, or the provision for such payment in
         cash or cash equivalents or otherwise in a manner satisfactory to the
         holders of Senior Indebtedness, the Holders of the Securities shall be
         subrogated to the extent of the payments or distributions made to the
         holders of such Senior Indebtedness pursuant to the provisions of this
         Article (equally and ratably with the holders of all indebtedness of
         the Company that by its express terms is subordinated to Senior
         Indebtedness of the Company to substantially the same extent as the
         Securities are subordinated to the Senior Indebtedness and is entitled
         to like rights of subrogation by reason of any payments or
         distributions made to holders of such Senior Indebtedness) to the
         rights of the holders of such Senior Indebtedness to receive payments
         and distributions of cash, property and securities applicable to the
         Senior Indebtedness until the principal of (and premium if any) and
         interest (including Additional Interest) on the Securities shall be
         paid in full. For purposes of such subrogation, no payments or
         distributions to the holders of the Senior Indebtedness of any cash,
         property or securities to which the Holders of the Securities or the
         Trustee would be entitled except for the provisions of this Article,
         and no payments over pursuant to the provisions of this Article to the
         holders of Senior Indebtedness by Holders of the Securities or the
         Trustee, shall, as among the Company, its creditors other than holders
         of Senior Indebtedness, and the Holders of the Securities, be deemed to
         be a payment or distribution by the Company to or on account of the
         Senior Indebtedness.

                SECTION 13.5.  Provisions Solely to Define Relative Rights.

                The provisions of this Article are and are intended solely for
         the purpose of defining the relative rights of the Holders of the
         Securities on the one hand and the holders of Senior Indebtedness on
         the other hand. Nothing contained in this Article or elsewhere in this
         Indenture or in the Securities is intended to or shall (a) impair, as
         between the Company and the Holders of the Securities, the obligations
         of the Company, which are absolute and unconditional, to pay to the
         Holders of the Securities the principal of (and premium, if any) and
         interest (including any Additional Interest) on the Securities as and
         when the same shall become due and payable in accordance with their
         terms; or (b) affect the relative rights against the Company of the
         Holders of the Securities and creditors of the Company other than their
<PAGE>   96

                                       - 90 -


         rights in relation to the holders of Senior Indebtedness; or (c)
         prevent the Trustee or the Holder of any Security (or to the extent
         expressly provided herein, the holder of any Capital Security) from
         exercising all remedies otherwise permitted by applicable law upon
         default under this Indenture, including filing and voting claims in any
         Proceeding, subject to the rights, if any, under this Article of the
         holders of Senior Indebtedness to receive cash, property and securities
         otherwise payable or deliverable to the Trustee or such Holder.

                SECTION 13.6.  Trustee to Effectuate Subordination.

                Each Holder of a Security by his or her acceptance thereof
         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 provided in this Article and appoints the Trustee his
         or her attorney-in-fact for any and all such purposes.

                SECTION 13.7.  No Waiver of Subordination Provisions.

                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 be otherwise
         charged with.

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

                SECTION 13.8.  Notice to Trustee.

                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 to or by the Trustee in respect of
         the Securities. Notwithstanding the provisions of this Article 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 to or by the Trustee in respect of the
         Securities, unless and until the Trustee shall have received written
         notice thereof from the Company or a holder of Senior Indebtedness or
         from any trustee, agent or representative therefor; provided, however,
         that if the Trustee shall not have received the notice provided for in
         this Section at least two Business Days prior to the date upon which by
         the terms hereof any monies may become payable for any purpose
         (including, the payment of the principal of (and premium, if any, on)
         or interest (including any Additional Interest) on any Security), then,
         anything herein contained to the contrary notwithstanding, the Trustee
         shall have full power and authority to receive such monies and to apply
         the same to the purpose for which they were received and shall not be
         affected by any notice to the contrary that may be received by it
         within two Business Days prior to such date.

                Subject to the provisions of Section 6.1, the Trustee shall be
         entitled to rely on the delivery to it of a written notice by a Person
         representing himself or herself to be a holder of Senior Indebtedness
         (or a trustee or attorney-in-fact therefor) to establish that such
         notice has been given by a holder of Senior Indebtedness (or a trustee
         or attorney-in-fact therefor). 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 Senior Indebtedness to participate
         in any payment or distribution pursuant to this Article, the Trustee
         may request such Person to furnish evidence to the reasonable
         satisfaction of the Trustee as to the amount of 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, 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 13.9.  Reliance on Judicial Order or Certificate of
                               Liquidating Agent.

                Upon any payment or distribution of assets of the Company
         referred to in this Article, the Trustee, subject to the provisions of
         Section 6.1, and the Holders of the Securities shall be entitled to
         rely upon any order or decree entered by any court
<PAGE>   98

                                       - 92 -


         of competent jurisdiction in which such Proceeding is pending, or a
         certificate of the trustee in bankruptcy, receiver, conservator,
         liquidating trustee, custodian, assignee for the benefit of creditors,
         agent or other Person making such payment or distribution, delivered to
         the Trustee or to the Holders of Securities, for the purpose of
         ascertaining the Persons entitled to participate in such payment or
         distribution, the holders of the Senior Indebtedness and other
         indebtedness of the Company, the amount thereof or payable thereon, the
         amount or amounts paid or distributed thereon and all other facts
         pertinent thereto or to this Article.

                SECTION 13.10. Trustee Not Fiduciary for Holders of Senior
                               Indebtedness.

                The Trustee, in its capacity as trustee under this Indenture,
         shall not be deemed to owe any fiduciary duty to the holders of Senior
         Indebtedness and shall not be liable to any such holders if it shall in
         good faith mistakenly pay over or distribute to Holders of Securities
         or to the Company or to any other Person cash, property or securities
         to which any holders of Senior Indebtedness shall be entitled by virtue
         of this Article or otherwise.

                SECTION 13.11. Rights of Trustee as Holder of Senior
                               Indebtedness; Preservation of Trustee's
                               Rights.

                The Trustee in its individual capacity shall be entitled to all
         the rights set forth in this Article with respect to any Senior
         Indebtedness that may at any time be 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.

                SECTION 13.12. Article Applicable to Paying Agents.

                In case at any time any Paying Agent other than the Trustee
         shall have been appointed by the Company and be then acting hereunder,
         the term "Trustee" as used in this Article shall in such case (unless
         the context otherwise requires) be construed as extending to and
         including such Paying Agent within its meaning as fully for all intents
         and purposes as if such Paying Agent were named in this Article in
         addition to or in place of the Trustee.

                SECTION 13.13. Certain Conversions or Exchanges Deemed
                               Payment.

                For purposes of this Article only, (a) the issuance and delivery
         of junior securities upon conversion or exchange of Securities of any
         series shall not be deemed to constitute a
<PAGE>   99

                                       - 93 -


         payment or distribution on account of the principal of (or premium, if
         any, on) or interest (including any Additional Interest) on such
         Securities or on account of the purchase or other acquisition of such
         Securities, and (b) the payment, issuance or delivery of cash, property
         or securities (other than junior securities) upon conversion or
         exchange of a Security of any series shall be deemed to constitute
         payment on account of the principal of such security. For the purposes
         of this Section, the term "junior securities" means (i) shares of any
         stock of any class of the Company, and (ii) securities of the Company
         that are subordinated in right of payment to all Senior Indebtedness
         that may be outstanding at the time of issuance or delivery of such
         securities to substantially the same extent as, or to a greater extent
         than, the Securities are so subordinated as provided in this Article.

         Act, it is being effected in accordance with Rule 144A, Rule 904 of

                a person that the Owner and any person acting on its behalf
                reasonably believe is a "qualified institutional buyer" within
                the meaning of Rule 144A, acquiring for its own account or for
                the account of a qualified institutional buyer; and

                          (B) the Owner and any person acting on its behalf have
                taken reasonable steps to ensure that the Transferee is aware
                that the Owner may be relying on Rule 144A in connection with
                the transfer; and

                     (2)  Rule 904 Transfers.  If the transfer is being

                acting in behalf of any of the foregoing;

                          (B)  the offer of the Specified Securities was
                not made to a person in the United States;

                          (C)  either;

                               (i) at the time the buy order was originated, the
                     Transferee was outside the United States or the Owner and
                     any person acting on its behalf reasonably believed that
                     the Transferee was outside the United States, or

                               (ii) the transaction is being executed in, on or
                     through the facilities of the Eurobond market, as regulated
                     by the Association of International Bond Dealers, or

                     Rule 902 of Regulation S have been made in the United
                     States by or on behalf of the Owner or any affiliate
                     thereof; and

                          (E) the transaction is not part of a plan or scheme to
                     evade the registration requirements of the Securities Act.

                (3)  Rule 144 Transfers.  If the transfer is being effected
         pursuant to Rule 144:

                     (A) the transfer is occurring after a holding period of at
                least two years (computed in accordance with paragraph (d) of
                Rule 144) has elapsed since the date the Specified Securities

                is being effected in accordance with the applicable amount,
                manner of sale and notice requirements of paragraphs (e), (f)

                     (B) the transfer is occurring after a holding period by the
                Owner of at least three years has elapsed since the date the
                Specified Securities were acquired from the Company or from an
                affiliate (as such term is defined in Rule 144) of the Company,
                whichever is later, and the Owner is not, and during the
                preceding three months has not been, an affiliate of the
                Company; or

                     (C) the Owner is a Qualified Institutional Buyer under Rule
                144A or has acquired the Securities otherwise in accordance with
                Sections (1), (2) or (3) hereof and is transferring the
                Securities to an institutional accredited investor in a

         any material respect the interests of the holders of the Outstanding
         Capital Securities. In no event shall the Administrators or the Issuer
         Trustees be liable to the Issuer Trust or the Holders for any failure

         administered by the Property Trustee for the benefit of the Issuer
         Trust and the Holders in accordance with this Trust Agreement.

         distribution as herein provided, including (and subject to) any
         priority of payments provided for herein.

                (b) The Property Trustee shall deposit in the Payment Account,
         promptly upon receipt, all payments of principal of or interest on, and
         any other payments or proceeds with respect to, the Junior Subordinated
         Debentures. Amounts held in the Payment Account shall not be invested
         by the Property Trustee pending distribution thereof.


                                   ARTICLE IV

                            DISTRIBUTIONS; REDEMPTION

                SECTION 4.1. Distributions.

                (a) The Trust Securities represent undivided beneficial
         interests in the Trust Property, and Distributions (including
         Distributions of Additional Amounts) will be made on the Trust
         Securities at the rate and on the dates that payments of interest
         (including payments of Additional Interest, as defined in the
         Indenture) are made on the Junior Subordinated Debentures. Accordingly:

                     (i) Distributions on the Trust Securities shall be
                cumulative and will accumulate whether or not there are funds of
                the Issuer Trust available for the payment of Distributions.
                Distributions shall accumulate from May __, 1997, and, except in
                the event (and to the extent) that the Depositor exercises its
                right to defer the payment of interest on the Debentures
                pursuant to the Indenture, shall be payable quarterly in arrears
                on March 31, June 30, September 30 and December 31 of each year,
                commencing on September 30, 1997. If any date on which a
                Distribution is otherwise payable on the Trust
<PAGE>   26
                                     - 21 -



                Securities is not a Business Day, then the payment of such
                Distribution shall be made on the next succeeding day that is a
                Business Day (without any interest or other payment in respect
                of any such delay), with the same force and effect as if made on
                the date on which such payment was originally payable (each date
                on which distributions are payable in accordance with this
                Section 4.1(a), a "Distribution Date"). The amount of each
                Distribution shall include amounts accrued through such
                applicable Distribution Date.

                     (ii) The Trust Securities shall be entitled to
                Distributions payable at a rate of ____% per annum of the
                Liquidation Amount of the Trust Securities. The amount of
                Distributions payable for any period less than a full
                Distribution period shall be computed on the basis of a 360-day
                year of twelve 30-day months and the actual number of days
                elapsed in a partial month in a period. Distributions payable
                for each full Distribution period will be computed by dividing
                the rate per annum by four. The amount of Distributions payable
                for any period shall include any Additional Amounts in respect
                of such period.


                     (iii) So long as no Debenture Event of Default has occurred
                and is continuing, the Depositor has the right under the
                Indenture to defer the payment of interest on the Junior
                Subordinated Debentures at any time and from time to time for a
                period not exceeding 20 consecutive quarterly periods (an
                "Extension Period"), provided that no Extension Period may
                extend beyond September 30, 2027. As a consequence of any such
                deferral, quarterly Distributions on the Trust Securities by the
                Trust will also be deferred (and the amount of Distributions to
                which Holders of the Trust Securities are entitled will
                accumulate additional Distributions thereon at the rate per
                annum of ____% per annum, compounded quarterly) from the
                relevant payment date for such Distributions, computed on the
                basis of a 360- day year of twelve 30-day months and the actual
                days elapsed in a partial month in such period. Additional
                Distributions payable for each full Distribution period will be
                computed by dividing the rate per annum by four (4). The term
                "Distributions" as used in Section 4.1 shall include any such
                additional Distributions provided pursuant to this Section
                4.1(a)(iii).

                     (iv) Distributions on the Trust Securities shall be made by
                the Property Trustee from the Payment Account and shall be
                payable on each Distribution Date only to the extent that the
                Issuer Trust has funds then on hand and available in the Payment
                Account for the payment of such Distributions.

                (b) Distributions on the Trust Securities with respect to a
         Distribution Date shall be payable to the Holders thereof as they
         appear on the Securities Register for the Trust Securities at the close
         of business on the relevant record date, which shall be at the close of
         business on the 15th day of March, June, September or December (whether
         or not a Business Day).

                SECTION 4.2. Redemption.

                (a) On each Junior Subordinated Debenture Redemption Date and on
         the Stated Maturity of the Junior Subordinated Debentures, the Issuer
         Trust will be required to redeem a Like Amount of Trust Securities at
         the Redemption Price.

                (b) Notice of redemption shall be given by the Property Trustee
         by first-class mail, postage prepaid, mailed not less than 30 nor more
         than 60 days prior to the Redemption Date to each Holder of Trust
         Securities to be redeemed, at such Holder's address appearing in the
         Security Register. All notices of redemption shall state:

                     (i) the Redemption Date;

                     (ii) the Redemption Price, or if the Redemption Price
                cannot be calculated prior to the time the notice is required to
                be sent, the estimate of the Redemption Price provided pursuant
                to the Indenture together with a statement that it is an
                estimate and that the actual Redemption Price will be calculated
                on the third Business Day prior to the Redemption Date (and if
                an estimate is provided, a further notice shall be sent of the
                actual Redemption Price on the date, or as soon as practicable
                thereafter, that notice of such actual Redemption Price is
                received pursuant to the Indenture);

                     (iii) the CUSIP number or CUSIP numbers of the Capital
                Securities affected;

                     (iv) if less than all the Outstanding Trust Securities are
                to be redeemed, the identification and the total Liquidation
                Amount of the particular Trust Securities to be redeemed;

                     (v) that on the Redemption Date the Redemption Price will
                become due and payable upon each such Trust Security to be
                redeemed and that Distributions thereon will cease to accumulate
                on and after said date, except as provided in Section 4.2(d)
                below; and
<PAGE>   28
                                     - 23 -




                     (vi) the place or places where Trust Securities are to be
                surrendered for the payment of the Redemption Price.

                The Issuer Trust in issuing the Trust Securities shall use
         "CUSIP" numbers, and the Property Trustee shall indicate the "CUSIP"
         numbers of the Trust Securities in notices of redemption and related
         materials as a convenience to Holders; provided that any such notice
         may state that no representation is made as to the correctness of such
         numbers either as printed on the Trust Securities or as contained in
         any notice of redemption and related material.

                (c) The Trust Securities redeemed on each Redemption Date shall
         be redeemed at the Redemption Price with the applicable proceeds from
         the contemporaneous redemption of Junior Subordinated Debentures.
         Redemptions of the Trust Securities shall be made and the Redemption
         Price shall be payable on each Redemption Date only to the extent that
         the Issuer Trust has 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 Capital Securities, then, by 12:00 noon, New York City
         time, on the Redemption Date, subject to Section 4.2(c), the Property
         Trustee will, with respect to Capital Securities held in global form,
         irrevocably deposit with the Clearing Agency for such Capital
         Securities, to the extent available therefor, funds sufficient to pay
         the applicable Redemption Price and will give such Clearing Agency
         irrevocable instructions and authority to pay the Redemption Price to
         the Holders of the Capital Securities. With respect to Capital
         Securities that are not held in global form, the Property Trustee,
         subject to Section 4.2(c), will irrevocably deposit with the Paying
         Agent, to the extent available therefor, funds sufficient to pay the
         applicable Redemption Price and will give the Paying Agent irrevocable
         instructions and authority to pay the Redemption Price to the Holder of
         the Capital Securities upon surrender of their Capital Securities
         Certificates. Notwithstanding the foregoing, 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 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 Holders holding Trust
         Securities so called for redemption will cease, except the right of
         such Holders to receive the Redemption Price and any Distribution
         payable in respect of the Trust Securities on or prior to the
         Redemption Date, but without interest, and such Securities will cease
         to be Outstanding. In the event that any date on which any applicable
         Redemption Price is payable is not a Business Day, then payment of
<PAGE>   29
                                     - 24 -



         the applicable Redemption Price payable on such date will be made on
         the next succeeding day that is a Business Day (and without any
         interest or other payment in respect of any such delay), except that,
         if such Business Day falls in the next calendar year, such payment will
         be made on the immediately preceding Business Day, in each case, with
         the same force and effect as if made on such date. In the event that
         payment of the Redemption Price in respect of any Trust Securities
         called for redemption is improperly withheld or refused and not paid
         either by the Issuer Trust or by the Depositor pursuant to the
         Guarantee Agreement, Distributions on such Trust Securities will
         continue to accumulate, as set forth in Section 4.1, from the
         Redemption Date originally established by the Issuer Trust for such
         Trust Securities to the date such applicable Redemption Price is
         actually paid, in which case the actual payment date will be the date
         fixed for redemption for purposes of calculating the applicable
         Redemption Price.

                (e) Subject to Section 4.3(a), if less than all the Outstanding
         Trust Securities are to be redeemed on a Redemption Date, then the
         particular Capital Securities to be redeemed shall be selected not more
         than 60 days prior to the Redemption Date by the Property Trustee from
         the Outstanding Capital Securities not previously called for redemption
         in such a manner as the Property Trustee shall deem fair and
         appropriate.

                SECTION 4.3. Subordination of Common Securities.

                (a) Payment of Distributions (including Additional Amounts, if
         applicable) on, the Redemption Price of, and the Liquidation
         Distribution in respect of, the Trust Securities, as applicable, shall
         be made, subject to Section 4.2(e), pro rata among the Common
         Securities and the Capital Securities based on the Liquidation Amount
         of such Trust Securities; provided, however, that if on any
         Distribution Date or Redemption Date any Event of Default resulting
         from a Debenture Event of Default in Section 5.1(1) or 5.1(2) of the
         Indenture shall have occurred and be continuing, no payment of any
         Distribution (including any Additional Amounts) on, Redemption Price
         of, or Liquidation Distribution in respect of, any Common Security, and
         no other payment on account of the redemption, liquidation or other
         acquisition of Common Securities, shall be made unless payment in full
         in cash of all accumulated and unpaid Distributions (including any
         Additional Amounts) on all Outstanding Capital 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 Capital Securities then called for redemption,
         or in the case of payment of the Liquidation Distribution the full
         amount of such Liquidation Distribution on all Outstanding Capital
         Securities, shall have been made or provided for, and all funds
         immediately available to the Property Trustee shall first be applied to
         the
<PAGE>   30
                                     - 25 -



         payment in full in cash of all Distributions (including any Additional
         Amounts) on, or the Redemption Price of, Capital Securities then due
         and payable. The existence of an Event of Default does not entitle the
         Holders of Capital Securities to accelerate the maturity thereof.

                (b) In the case of the occurrence of any Event of Default
         resulting from any Debenture Event of Default, the Holder of the Common
         Securities shall have no right to act with respect to any such Event of
         Default under this Trust Agreement until the effects of all such Events
         of Default with respect to the Capital Securities have been cured,
         waived or otherwise eliminated. Until all such Events of Default under
         this Trust Agreement with respect to the Capital Securities have been
         so cured, waived or otherwise eliminated, the Property Trustee shall
         act solely on behalf of the Holders of the Capital Securities and not
         on behalf of the Holder of the Common Securities, and only the Holders
         of the Capital Securities will have the right to direct the Property
         Trustee to act on their behalf.

                SECTION 4.4. Payment Procedures.

                Payments of Distributions (including any Additional Amounts) in
         respect of the Capital Securities shall be made by check mailed to the
         address of the Person entitled thereto as such address shall appear on
         the Securities Register or, if the Capital Securities are held by a
         Clearing Agency, such Distributions shall be made to the Clearing
         Agency in immediately available funds, which will credit the relevant
         accounts on the applicable Distribution Dates. Payments of
         Distributions to Holders of $1,000,000 or more in aggregate Liquidation
         Amount of Capital Securities may be made by wire transfer of
         immediately available funds upon written request of such Holder of
         Capital Securities to the Securities Registrar not later than 15
         calendar days prior to the date on which the Distribution is payable.
         Payments in respect of the Common Securities shall be made in such
         manner as shall be mutually agreed between the Property Trustee and the
         Holder of the Common Securities.

                SECTION 4.5. Tax Returns and Reports.

                The Administrators 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 required to be filed by
         or in respect of the Issuer Trust. In this regard, the Administrators
         shall (a) prepare and file (or cause to be prepared and filed) all
         Internal Revenue Service forms required to be filed in respect of the
         Issuer Trust in each taxable year of the Issuer Trust and (b) prepare
         and furnish (or cause to be prepared and furnished) to each Holder all
         Internal Revenue Service forms required to be provided by the Issuer
         Trust. The
<PAGE>   31
                                     - 26 -




         Administrators shall provide the Depositor and the Property Trustee
         with a copy of all such returns and reports promptly after such filing
         or furnishing. The Issuer Trustees shall comply with United States
         Federal withholding and backup withholding tax laws and information
         reporting requirements with respect to any payments to Holders under
         the Trust Securities.

                On or before December 15 of each year during which any Capital
         Securities are outstanding, the Administrators shall furnish to the
         Paying Agent such information as may be reasonably requested by the
         Property Trustee in order that the Property Trustee may prepare the
         information which it is required to report for such year on Internal
         Revenue Service Forms 1096 and 1099 pursuant to Section 6049 of the
         Internal Revenue Code of 1986, as amended. Such information shall
         include the amount of original issue discount includible in income for
         each outstanding Capital Security during such year.

                SECTION 4.6. Payment of Taxes; Duties, Etc. of the Issuer Trust.

                Upon receipt under the Junior Subordinated Debentures of
         Additional Sums, the Property Trustee shall promptly pay any taxes,
         duties or governmental charges of whatsoever nature (other than
         withholding taxes) imposed on the Issuer Trust by the United States or
         any other taxing authority.

                SECTION 4.7. Payments under Indenture or Pursuant to Direct
         Actions.

                Any amount payable hereunder to any Holder of Capital Securities
         shall be reduced by the amount of any corresponding payment such Holder
         has directly received pursuant to Section 5.8 of the Indenture or
         Section 5.13 of this Trust Agreement.

                SECTION 4.8.  Liability of the Holder of Common Securities.

                The Holder of Common Securities shall be liable for the debts
         and obligations of the Issuer Trust as set forth in Section 6.7 of the
         Indenture regarding allocation of expenses.

         Securities are outstanding, the Depositor shall be the sole beneficial
         owner of the Issuer Trust.

                SECTION 5.2. The Trust Securities Certificates.

                (a) The Trust Securities Certificates shall be executed on
         behalf of the Issuer Trust by manual or facsimile signature of at least
         one Administrator except as provided in Section 5.3. Trust Securities
         Certificates bearing the manual signatures of individuals who were, at
         the time when such signatures shall have been affixed, authorized to
         sign on behalf of the Issuer 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 Holder, and shall be entitled to the rights and subject to the
         obligations of a Holder hereunder, upon due registration of such Trust
         Securities Certificate in such transferee's name pursuant to Section

         Certificates shall be issued in the form of one or more fully
         registered Global Capital Securities Certificates which will be
         deposited with or on behalf of the Depositary and registered in the
         name of the Depositary's nominee. Unless and until it is exchangeable
         in whole or in part for the Capital Securities in definitive form, a
         global security may not be transferred except as a whole by the
         Depositary to a nominee of the Depositary or by a nominee of the
         Depositary to the Depositary or another nominee of the Depositary or by
         the Depositary or any such nominee to a successor of such Depositary or
         a nominee of such successor.

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

                SECTION 5.3. Execution and Delivery of Trust Securities

         Securities Certificates, in an aggregate Liquidation Amount as provided
         in Sections 2.4 and 2.5, to be executed on behalf of the Issuer Trust
         and delivered to the Property Trustee and upon such delivery the
         Property Trustee shall authenticate such Trust Securities Certificates
         and deliver such Trust Securities Certificates upon the written order
         of the Trust, executed by the Administrators thereof, without further
         corporate action by the Trust, in authorized denominations.

                SECTION 5.4. Global Capital Security.

                (a) Any Global Capital Security issued under this Trust
         Agreement shall be registered in the name of the nominee of the
         Clearing Agency and delivered to such custodian therefor, and such
         Global Capital Security shall constitute a single Capital Security for
         all purposes of this Trust Agreement.

                (b) Notwithstanding any other provision in this Trust Agreement,
         a Global Capital Security may not be exchanged in whole or in part for
         Capital Securities registered, and no transfer of the Global Capital
         Security in whole or in part may be registered, in the name of any
         Person other than the Clearing Agency for such Global Capital Security,
         or its nominee thereof unless (i) such Clearing Agency advises the
         Property Trustee in writing that such Clearing Agency is no longer
         willing or able to properly discharge its responsibilities as Clearing
         Agency with respect to such Global Capital Security, and the Depositor
         is unable to locate a qualified successor, (ii) the Issuer Trust at its
         option advises the Depositary in writing that it elects to terminate
         the book-entry system through the Clearing Agency, or (iii) there shall
         have occurred and be continuing an Event of Default.

                (c) If a Capital Security is to be exchanged in whole or in part
         for a beneficial interest in a Global Capital Security, then either (i)
         such Global Capital Security shall be so surrendered for exchange or
         cancellation as provided in this Article V or (ii) the Liquidation
         Amount thereof shall be reduced or increased by an amount equal to the
         portion thereof to be so exchanged or cancelled, or equal to the
         Liquidation Amount of such other Capital Security to be so exchanged
         for a beneficial interest therein, as the case may be, by means of an
         appropriate adjustment made on the records of the Security Registrar,
         whereupon the Property Trustee, in accordance with the Applicable
         Procedures, shall instruct the Clearing Agency or its authorized
         representative to make a corresponding adjustment to its records. Upon
         any such surrender or adjustment of a Global Capital Security by the
         Clearing Agency, accompanied by registration instructions, the Property
         Trustee shall, subject to Section 5.4(b) and as otherwise provided in
         this Article V, authenticate and deliver any Capital Securities
         issuable in exchange for such Global Capital Security (or any portion
         thereof) in accordance with the instructions of the Clearing Agency.
         The Property Trustee shall not be liable for any delay in delivery of
         such instructions and may conclusively rely on, and shall be fully
         protected in relying on, such instructions.

                (d) Every Capital Security authenticated and delivered upon
         registration of transfer of, or in exchange for or in lieu of, a Global
         Capital Security or any portion thereof, whether pursuant to this
         Article V or Article IV or otherwise, shall be
<PAGE>   34
                                     - 29 -




         authenticated and delivered in the form of, and shall be, a Global
         Capital Security, unless such Global Capital Security is registered in
         the name of a Person other than the Clearing Agency for such Global
         Capital Security or a nominee thereof.

                (e) The Clearing Agency or its nominee, as the registered owner
         of a Global Capital Security, shall be considered the Holder of the
         Capital Securities represented by such Global Capital Security for all
         purposes under this Trust Agreement and the Capital Securities, and
         owners of beneficial interests in such Global Capital Security shall
         hold such interests pursuant to the Applicable Procedures and, except
         as otherwise provided herein, shall not be entitled to receive physical
         delivery of any such Capital Securities in definitive form and shall
         not be considered the Holders thereof under this Trust Agreement.
         Accordingly, any such owner's beneficial interest in the Global Capital
         Security shall be shown only on, and the transfer of such interest
         shall be effected only through, records maintained by the Clearing
         Agency or its nominee. Neither the Property Trustee, the Securities
         Registrar nor the Depositor shall have any liability in respect of any
         transfers effected by the Clearing Agency.

                (f) The rights of owners of beneficial interests in a Global
         Capital Security shall be exercised only through the Clearing Agency
         and shall be limited to those established by law and agreements between
         such owners and the Clearing Agency.

                SECTION 5.5. Registration of Transfer and Exchange Generally;
         Certain Transfers and Exchanges; Capital Securities Certificates.

                (a) The Property Trustee shall keep or cause to be kept at its
         Corporate Trust Office a register or registers for the purpose of
         registering Capital Securities Certificates and transfers and exchanges
         of Capital Securities Certificates in which the registrar and transfer
         agent with respect to the Capital Securities (the "Securities
         Registrar"), subject to such reasonable regulations as it may
         prescribe, shall provide for the registration of Capital Securities
         Certificates and Common Securities Certificates (subject to Section
         5.11 in the case of Common Securities Certificates) and registration of
         transfers and exchanges of Capital Securities Certificates as herein
         provided. Such register is herein sometimes referred to as the
         "Securities Register." The Property Trustee is hereby appointed
         "Securities Registrar" for the purpose of registering Capital
         Securities and transfers of Capital Securities as herein provided.

                Upon surrender for registration of transfer of any Capital
         Security at the offices or agencies of the Property Trustee designated
         for that purpose, the Depositor shall execute, and authenticate and
         deliver, in the name of the designated transferee
<PAGE>   35
                                     - 30 -


         or transferees, one or more new Capital Securities of the same series
         of any authorized denominations of like tenor and aggregate principal
         amount and bearing such legends as may be required by this Trust
         Agreement.

                At the option of the Holder, Capital Securities may be exchanged
         for other Capital Securities of any authorized denominations, of like
         tenor and aggregate Liquidation Amount and bearing such legends as may
         be required by this Trust Agreement, upon surrender of the Capital
         Securities to be exchanged at such office or agency. Whenever any
         securities are so surrendered for exchange, the Property Trustee shall
         execute and authenticate and deliver the Capital Securities that the
         Holder making the exchange is entitled to receive.

                All Capital Securities issued upon any transfer or exchange of
         Capital Securities shall be the valid obligations of the Issuer Trust,
         evidencing the same debt, and entitled to the same benefits under this
         Trust Agreement, as the Capital Securities surrendered upon such
         transfer or exchange.

                Every Capital Security presented or surrendered for transfer or
         exchange shall (if so required by the Property Trustee) be duly
         endorsed, or be accompanied by a written instrument of transfer in form
         satisfactory to the Property Trustee and the Securities Registrar, duly
         executed by the Holder thereof or such Holder's attorney duly
         authorized in writing.

                No service charge shall be made to a Holder for any transfer or
         exchange of Capital Securities, but the Property Trustee may require
         payment of a sum sufficient to cover any tax or other governmental
         charge that may be imposed in connection with any transfer or exchange
         of Capital Securities.

                Neither the Issuer Trust nor the Property Trustee shall be
         required, pursuant to the provisions of this Section, (i) to issue,
         register the transfer of or exchange any Capital Security during a
         period beginning at the opening of business 15 days before the day of
         selection for redemption of Capital Securities pursuant to Article IV
         and ending at the close of business on the day of mailing of the notice
         of redemption, or (ii) to register the transfer of or exchange any
         Capital Security so selected for redemption in whole or in part,
         except, in the case of any such Capital Security to be redeemed in
         part, any portion thereof not to be redeemed.

                (b) Certain Transfers and Exchanges. Trust Securities may only
         be transferred, in whole or in part, in accordance with the terms and
         conditions set forth in this Trust Agreement. Any transfer or purported
         transfer of any Trust Security not made in accordance with this Trust
         Agreement shall be null and void.

                     (i) Non Global Security to Non Global Security. A Trust
                Security that is not a Global Capital Security may be
                transferred, in whole or in part, to a Person who takes delivery
                in the form of another Trust Security that is not a Global
                Security as provided in Section 5.5(a).

                     (ii) Free Transferability. Subject to this Section 5.5,
                Capital Securities shall be freely transferable.

                     (iii) Exchanges Between Global Capital Security and
                Non-Global Capital Security. A beneficial interest in a Global
                Capital Security may be exchanged for a Capital Security that is
                not a Global Capital Security as provided in Section 5.4.

                SECTION 5.6. 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 and the Administrators 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
         Administrators, or any one of them, on behalf of the Issuer Trust shall
         execute and make available for delivery, and the Property Trustee shall
         authenticate, 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, the Administrators 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
         shall constitute conclusive evidence of an undivided beneficial
         interest in the assets of the Issuer Trust corresponding to that
         evidenced by the lost, stolen or destroyed Trust Certificate, as if
         originally issued, whether or not the lost, stolen or destroyed Trust
         Securities Certificate shall be found at any time.

                SECTION 5.7. Persons Deemed Holders.

                The Issuer Trustees, the Securities Registrar or the Depositor
         shall treat the Person in whose name any Trust Securities are issued as
         the owner of such Trust Securities for the purpose of receiving
         Distributions and for all other purposes
<PAGE>   37
                                     - 32 -




         whatsoever, and none of the Issuer Trustees, the Administrators, the
         Securities Registrar nor the Depositor shall be bound by any notice to
         the contrary.

                SECTION 5.8. Access to List of Holders' Names and Addresses.

                Each Holder and each Owner shall be deemed to have agreed not to
         hold the Depositor, the Property Trustee, or the Administrators
         accountable by reason of the disclosure of its name and address,
         regardless of the source from which such information was derived.

                SECTION 5.9. Maintenance of Office or Agency.

                The Property Trustee shall designate, with the consent of the
         Administrators, which consent shall not be unreasonably withheld, an
         office or offices or agency or agencies where Capital Securities
         Certificates may be surrendered for registration of transfer or
         exchange and where notices and demands to or upon the Issuer Trustees
         in respect of the Trust Securities Certificates may be served. The
         Property Trustee initially designates its Corporate Trust Office at
         Four Albany Street, New York, NY 10006, Attention: Corporate Trust and
         Agency Group - Corporate Market Services, as its corporate trust office
         for such purposes. The Property Trustee shall give prompt written
         notice to the Depositor, the Administrators and to the Holders of any
         change in the location of the Securities Register or any such office or
         agency.

                SECTION 5.10. Appointment of Paying Agent.

                The Paying Agent shall make Distributions to Holders from the
         Payment Account and shall report the amounts of such Distributions to
         the Property Trustee and the Administrators. Any Paying Agent shall
         have the revocable power to withdraw funds from the Payment Account
         solely for the purpose of making the Distributions referred to above.
         The Property Trustee may revoke such power and remove any Paying Agent
         in its sole discretion. The Paying Agent shall initially be the
         Property Trustee. Any Person acting as Paying Agent shall be permitted
         to resign as Paying Agent upon 30 days' written notice to the
         Administrators, and the Property Trustee. 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
         Property Trustee shall appoint a successor (which shall be a bank or
         trust company) that is reasonably acceptable to the Administrators to
         act as Paying Agent. Such successor Paying Agent or any additional
         Paying Agent appointed by the Administrators shall execute and deliver
         to the Issuer Trustees an instrument in which such successor Paying
         Agent or additional Paying Agent shall agree
<PAGE>   38
                                     - 33 -



         with the Issuer Trustees that as Paying Agent, such successor Paying
         Agent or additional Paying Agent will hold all sums, if any, held by it
         for payment to the Holders in trust for the benefit of the Holders
         entitled thereto until such sums shall be paid to such Holders. 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 8.1, 8.3 and 8.6 herein shall apply to the Bank also in its
         role as Paying Agent, for so long as the Bank 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 chosen by the Property Trustee unless
         the context requires otherwise.

                SECTION 5.11. Ownership of Common Securities by Depositor.

                At each Time of Delivery, the Depositor shall acquire and retain
         beneficial and record ownership of the Common Securities except (i) in
         connection with a consolidation or merger of the Depositor into another
         corporation or any conveyance, transfer or lease by the Depositor of
         its properties and assets substantially as an entirety to any Person,
         pursuant to Section 8.1 of the Indenture, or (ii) a transfer to an
         Affiliate of the Depositor in compliance with applicable law (including
         the Securities Act and applicable state securities and blue sky laws).
         To the fullest extent permitted by law, any attempted transfer of the
         Common Securities shall be void. The Administrators shall cause each
         Common Securities Certificate issued to the Depositor to contain a
         legend stating "THIS CERTIFICATE IS NOT TRANSFERABLE EXCEPT TO A
         SUCCESSOR IN INTEREST TO THE DEPOSITOR OR AN AFFILIATE OF THE DEPOSITOR
         IN COMPLIANCE WITH APPLICABLE LAW AND SECTION 5.11 OF THE TRUST
         AGREEMENT."

                SECTION 5.12. Notices to Clearing Agency.

                To the extent that a notice or other communication to the
         Holders is required under this Trust Agreement, for so long as Capital
         Securities are represented by a Global Capital Securities Certificate,
         the Administrators and the Issuer Trustees shall give all such notices
         and communications specified herein to be given to the Clearing Agency,
         and shall have no obligations to the Owners.

                SECTION 5.13. Rights of Holders.

                (a) The legal title to the Trust Property is vested exclusively
         in the Property Trustee (in its capacity as such) in accordance with
         Section 2.9, and the Holders shall not have any right or title therein
         other than the undivided beneficial ownership interest in the assets of
         the Issuer Trust conferred by
<PAGE>   39
                                     - 34 -




         their Trust Securities and they shall have no right to call for any
         partition or division of property, profits or rights of the Issuer
         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 and when issued and delivered to Holders against payment
         of the purchase price therefor will be fully paid and nonassessable by
         the Issuer Trust. The Holders of the Trust 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 Capital 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
         Junior Subordinated Debentures fail to declare the principal of all of
         the Junior Subordinated Debentures to be immediately due and payable,
         the Holders of at least 25% in Liquidation Amount of the Capital
         Securities then Outstanding shall have such right to make such
         declaration by a notice in writing to the Property Trustee, the
         Depositor and the Debenture Trustee.

                At any time after such a declaration of acceleration with
         respect to the Junior Subordinated Debentures has been made and before
         a judgment or decree for payment of the money due has been obtained by
         the Debenture Trustee as provided in the Indenture, the Holders of a
         majority in Liquidation Amount of the Capital Securities, by written
         notice to the Property Trustee, the Depositor and the Debenture
         Trustee, may rescind and annul such declaration and its consequences
         if:

                     (i) the Depositor has paid or deposited with the Debenture
                Trustee a sum sufficient to pay

                          (A) all overdue installments of interest on all of the
                     Junior Subordinated Debentures,

                          (B) any accrued Additional Interest on all of the
                     Junior Subordinated Debentures,

                          (C) the principal of any Junior Subordinated
                     Debentures which have become due otherwise than by such
                     declaration of acceleration and interest and Additional
                     Interest thereon at the rate borne by the Junior
                     Subordinated Debentures, and
<PAGE>   40
                                     - 35 -




                          (D) all sums paid or advanced by the Debenture Trustee
                     under the Indenture and the reasonable compensation,
                     expenses, disbursements and advances of the Debenture
                     Trustee and the Property Trustee, their agents and counsel;
                     and

                     (ii) all Events of Default with respect to the Junior
                     Subordinated Debentures, other than the non-payment of the
                     principal of the Junior Subordinated Debentures which has
                     become due solely by such acceleration, have been cured or
                     waived as provided in Section 5.13 of the Indenture.

                If the Property Trustee fails to annul any such declaration and
         waive such default, the Holders of at least a Majority in Liquidation
         Amount of the Capital Securities shall also have the right to rescind
         and annul such declaration and its consequences by written notice to
         the Depositor, the Property Trustee and the Debenture Trustee, subject
         to the satisfaction of the conditions set forth in Clause (i) and (ii)
         of this Section 5.13.

                The Holders of at least a Majority in Liquidation Amount of the
         Capital Securities may, on behalf of the Holders of all the Capital
         Securities, waive any past default under the Indenture, except a
         default in the payment of principal or interest (unless such default
         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) or a default in respect of a
         covenant or provision which under the Indenture cannot be modified or
         amended without the consent of the holder of each outstanding Junior
         Subordinated Debentures. No such rescission shall affect any subsequent
         default or impair any right consequent thereon.

                Upon receipt by the Property Trustee of written notice declaring
         such an acceleration, or rescission and annulment thereof, by Holders
         of the Capital Securities all or part of which is represented by Global
         Capital Securities, a record date shall be established for determining
         Holders of Outstanding Capital Securities entitled to join in such
         notice, which record date shall be at the close of business on the day
         the Property Trustee receives such notice. The Holders on such record
         date, or their duly designated proxies, and only such Persons, shall be
         entitled to join in such notice, whether or not such Holders remain
         Holders after such record date; provided, that, unless such declaration
         of acceleration, or rescission and annulment, as the case may be, shall
         have become effective by virtue of the requisite percentage having
         joined in such notice prior to the day which is 90 days after such
         record date, such notice of declaration of acceleration, or rescission
         and annulment, as the case may be, shall automatically and without
         further action by any Holder be
<PAGE>   41
                                     - 36 -




         canceled and of no further effect. Nothing in this paragraph shall
         prevent a Holder, or a proxy of a Holder, from giving, after expiration
         of such 90-day period, a new written notice of declaration of
         acceleration, or rescission and annulment thereof, as the case may be,
         that is identical to a written notice which has been canceled pursuant
         to the proviso to the preceding sentence, in which event a new record
         date shall be established pursuant to the provisions of this Section
         5.13(b).

                (c) For so long as any Capital Securities remain Outstanding, to
         the fullest extent permitted by law and subject to the terms of this
         Trust Agreement and the Indenture, upon a Debenture Event of Default
         specified in Section 5.1(1) or 5.1(2) of the Indenture, any Holder of
         Capital Securities shall have the right to institute a proceeding
         directly against the Depositor, pursuant to Section 5.8 of the
         Indenture, for enforcement of payment to such Holder of the principal
         amount of or interest on Junior Subordinated Debentures having an
         aggregate principal amount equal to the aggregate Liquidation Amount of
         the Capital Securities of such Holder (a "Direct Action"). Except as
         set forth in Sections 5.13(b) and 5.13 (c), the Holders of Capital
         Securities shall have no right to exercise directly any right or remedy
         available to the holders of, or in respect of, the Junior Subordinated
         Debentures.


                                   ARTICLE VI

                        ACTS OF HOLDERS; MEETINGS; VOTING

                SECTION 6.1. Limitations on Holder's Voting Rights.

                (a) Except as provided in this Trust Agreement and in the
         Indenture and as otherwise required by law, no Holder of Capital
         Securities shall have any right to vote or in any manner otherwise
         control the administration, operation and management of the Issuer
         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 Holders from time to
         time as members of an association.

                (b) So long as any Junior Subordinated Debentures are held by
         the Property Trustee on behalf of the Issuer Trust, the Property
         Trustee 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 Property Trustee with
         respect to such Junior Subordinated Debentures, (ii) waive any past
         default that may be waived under Section 5.13 of the Indenture, (iii)
         exercise any right to rescind or annul a declaration that the principal
         of all the Junior Subordinated Debentures shall be due and payable or
         (iv) consent
<PAGE>   42
                                     - 37 -




         to any amendment, modification or termination of the Indenture or the
         Junior Subordinated Debentures, where such consent shall be required,
         without, in each case, obtaining the prior approval of the Holders of
         at least a Majority in Liquidation Amount of the Capital Securities,
         provided, however, that where a consent under the Indenture would
         require the consent of each Holder of Junior Subordinated Debentures
         affected thereby, no such consent shall be given by the Property
         Trustee without the prior written consent of each Holder of Capital
         Securities. The Property Trustee shall not revoke any action previously
         authorized or approved by a vote of the Holders of Capital Securities,
         except by a subsequent vote of the Holders of Capital Securities. The
         Property Trustee shall notify all Holders of the Capital Securities of
         any notice of default received with respect to the Junior Subordinated
         Debentures. In addition to obtaining the foregoing approvals of the
         Holders of the Capital Securities, prior to taking any of the foregoing
         actions, the Issuer Trustees shall, at the expense of the Depositor,
         obtain an Opinion of Counsel experienced in such matters to the effect
         that such action will not cause the Issuer Trust to be taxable as a
         corporation for United States Federal income tax purposes.

                (c) If any proposed amendment to the Trust Agreement provides
         for, or the Issuer Trust otherwise proposes to effect, (i) any action
         that would adversely affect in any material respect the interests,
         powers, preferences or special rights of the Capital Securities,
         whether by way of amendment to the Trust Agreement or otherwise, or
         (ii) the dissolution of the Issuer Trust, other than pursuant to the
         terms of this Trust Agreement, then the Holders of Outstanding Trust
         Securities as a class will 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 Capital Securities. Notwithstanding any other provision
         of this Trust Agreement, no amendment to this Trust Agreement may be
         made if, as a result of such amendment, it would cause the Issuer Trust
         to be taxable as a corporation for United States Federal income tax
         purposes.

                SECTION 6.2. Notice of Meetings.

                Notice of all meetings of the Holders, stating the time, place
         and purpose of the meeting, shall be given by the Property Trustee
         pursuant to Section 10.8 to each Holder 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.

                SECTION 6.3. Meetings of Holders.

                No annual meeting of Holders is required to be held. The
         Property Trustee, however, shall call a meeting of Holders to vote on
         any matter upon the written request of the Holders of record of 25% of
         the aggregate Liquidation Amount of the Capital Securities and the
         Administrators or the Property Trustee may, at any time in their
         discretion, call a meeting of Holders of Capital Securities to vote on
         any matters as to which Holders are entitled to vote.

                Holders of at least a Majority in Liquidation Amount of the
         Capital Securities, present in person or represented by proxy, shall
         constitute a quorum at any meeting of Holders of the Capital
         Securities.

                If a quorum is present at a meeting, an affirmative vote by the
         Holders of record present, in person or by proxy, holding Capital
         Securities representing at least a Majority in Liquidation Amount of
         the Capital Securities held by the Holders present, either in person or
         by proxy, at such meeting shall constitute the action of the Holders of
         Capital Securities, unless this Trust Agreement requires a greater
         number of affirmative votes.

                SECTION 6.4. Voting Rights.

                Holders shall be entitled to one vote for each $25 of
         Liquidation Amount represented by their Outstanding Trust Securities in
         respect of any matter as to which such Holders are entitled to vote.

                SECTION 6.5. Proxies, etc.

                At any meeting of Holders, any Holder 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 Property Trustee, or
         with such other officer or agent of the Issuer Trust as the Property
         Trustee may direct, for verification prior to the time at which such
         vote shall be taken. Pursuant to a resolution of the Property Trustee,
         proxies may be solicited in the name of the Property Trustee or one or
         more officers of the Property Trustee. Only Holders of record shall be
         entitled to vote. 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 Holder shall be deemed
         valid unless challenged at or prior to its exercise, and the burden of
         proving invalidity shall
<PAGE>   44
                                     - 39 -


         rest on the challenger. No proxy shall be valid more than three years
         after its date of execution.

                SECTION 6.6. Holder Action by Written Consent.

                Any action which may be taken by Holders at a meeting may be
         taken without a meeting if Holders holding at least a Majority in
         Liquidation Amount of all Trust Securities entitled to vote in respect
         of such action (or such larger proportion thereof as shall be required
         by any other provision of this Trust Agreement) shall consent to the
         action in writing.

                SECTION 6.7. Record Date for Voting and Other Purposes.

                For the purposes of determining the Holders 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 Administrators
         or Property Trustee may from time to time fix a date, not more than 90
         days prior to the date of any meeting of Holders or the payment of a
         distribution or other action, as the case may be, as a record date for
         the determination of the identity of the Holders of record for such
         purposes.

                SECTION 6.8. Acts of Holders.

                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 Holders may be embodied in and evidenced by
         one or more instruments of substantially similar tenor signed by such
         Holders 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 the
         Property Trustee. Such instrument or instruments (and the action
         embodied therein and evidenced thereby) are herein sometimes referred
         to as the "Act" of the Holders 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 8.1) conclusive in favor of the
         Issuer Trustees, if made in the manner provided in this Section.

                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
<PAGE>   45
                                     - 40 -




         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 Issuer Trustee or Administrator receiving the same deems
         sufficient.

                The ownership of Trust Securities shall be proved by the
         Securities Register.

                Any request, demand, authorization, direction, notice, consent,
         waiver or other Act of the Holder of any Trust Security shall bind
         every future Holder of the same Trust Security and the Holder 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 Issuer Trustees, the
         Administrators or the Issuer Trust in reliance thereon, whether or not
         notation of such action is made upon such Trust Security.

                Without limiting the foregoing, a Holder entitled hereunder to
         take any action hereunder with regard to any particular Trust Security
         may do so with regard to all or any part of the Liquidation Amount of
         such Trust Security or by one or more duly appointed agents each of
         which may do so pursuant to such appointment with regard to all or any
         part of such Liquidation Amount.

                If any dispute shall arise among the Holders, the Administrators
         or the Issuer Trustees with respect to the authenticity, validity or
         binding nature of any request, demand, authorization, direction,
         consent, waiver or other Act of such Holder or Issuer Trustee under
         this Article VI, then the determination of such matter by the Property
         Trustee shall be conclusive with respect to such matter.

                A Holder may institute a legal proceeding directly against the
         Depositor under the Guarantee Agreement to enforce its rights under the
         Guarantee Agreement without first instituting a legal proceeding
         against the Guarantee Trustee (as defined in the Guarantee Agreement),
         the Issuer Trust, any Issuer Trustee, any Administrator or any person
         or entity.

                SECTION 6.9. Inspection of Records.

                Upon reasonable notice to the Administrators and the Property
         Trustee, the records of the Issuer Trust shall be open to inspection by
         Holders during normal business hours for any purpose reasonably related
         to such Holder's interest as a Holder.

                The Depositor hereby represents and warrants for the benefit of
         the Holders that:

         Delivery on behalf of the Issuer Trust have been duly authorized and
         will have been duly and validly executed, and, subject to payment
         therefor, issued and delivered by the Issuer Trustees pursuant to the
         terms and provisions of, and in accordance with the requirements of,

                                  ARTICLE VIII

                     THE ISSUER TRUSTEES; THE ADMINISTRATORS

                SECTION 8.1. Certain Duties and Responsibilities.

                (a) The duties and responsibilities of the Issuer Trustees and
         the Administrators 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 Issuer Trustees or the Administrators 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 or them. 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 Issuer Trustees or the Administrators shall
         be subject to the provisions of this Section. Nothing in this Trust
         Agreement shall be construed to release an Administrator from liability
         for his or its own negligent action, his or its own negligent failure
         to act, or his or its own willful misconduct. To the extent that, at
         law or in equity, an Issuer Trustee or Administrator has duties and
         liabilities relating to the Issuer Trust or to the Holders, such Issuer
         Trustee or Administrator shall not be liable to the Issuer Trust or to
         any Holder for such Issuer Trustee's or Administrator'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 Issuer Trustees and Administrators otherwise
         existing at law or in equity, are agreed by the Depositor and the
         Holders to replace his or such other duties and liabilities of the
         Issuer Trustees and Administrators.

                (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. Each Holder, by his or its acceptance
         of a Trust Security, agrees that he or it will look solely to the
         revenue and proceeds from the Trust Property to the extent legally
         available for distribution to it or him as herein provided and that
         neither the Issuer Trustees nor the Administrators are personally
         liable to it or him for any amount distributable in respect of any
         Trust Security or for any other liability in respect of any Trust
         Security. This Section 8.1(b) does not limit the liability of the
         Issuer Trustees

         expressly set forth elsewhere in this Trust Agreement or, in the case
         of the Property Trustee, in the Trust Indenture Act.

                (c) The Property 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 Trust Agreement (including pursuant to
         Section 10.10), and no implied covenants shall be read into this Trust
         Agreement against the Property Trustee. If an Event of Default has
         occurred (that has not been cured or waived pursuant to Section 5.13 of
         the Indenture), the Property Trustee shall enforce this Trust Agreement
         for the benefit of the Holders and shall exercise such of the rights
         and powers vested in it by this Trust Agreement, 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 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) 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 Property Trustee
                     shall be determined solely by the express provisions of
                     this Trust Agreement (including pursuant to Section 10.10),
                     and the Property Trustee shall not be liable except for the
                     performance of such duties and obligations as are
                     specifically set forth in this Trust Agreement (including
                     pursuant to Section 10.10); and

                          (B) in the absence of bad faith on the part of the
                     Property Trustee, the Property 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 Property Trustee and conforming
                     to the requirements of this Trust Agreement; but in the
                     case of any such certificates or opinions that by any
                     provision hereof or of the Trust Indenture Act are
                     specifically required to be furnished to the Property
                     Trustee, the Property Trustee shall be under a duty to
                     examine the same to determine whether or not they conform
                     to the requirements of this Trust Agreement;

                     (ii) 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;

                     (iii) 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 at least a
                Majority in Liquidation Amount of the Capital 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;

                     (iv) the Property Trustee's sole duty with respect to the
                custody, safe keeping and physical preservation of the Junior
                Subordinated 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;

                     (v) 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 3.1 and except to the extent
                otherwise required by law;

                     (vi) the Property Trustee shall not be responsible for
                monitoring the compliance by the Administrators or the Depositor
                with their respective duties under this Trust Agreement, nor
                shall the Property Trustee be liable for the default or
                misconduct of any other Issuer Trustee, the Administrators or
                the Depositor; and

                     (vii) no provision of this Trust Agreement shall require
                the Property 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 Property Trustee shall have reasonable grounds
                for believing that the repayment of such funds or liability is
                not reasonably assured to it under the
<PAGE>   51
                                     - 46 -




                terms of this Trust Agreement or adequate indemnity against such
                risk or liability is not reasonably assured to it.

                (e) The Administrators shall not be responsible for monitoring
         the compliance by the Issuer Trustee or the Depositor with their
         respective duties under this Trust Agreement, nor shall either
         Administrator be liable for the default or misconduct of any other
         Administrator, the Issuer Trustees or the Depositor.

                SECTION 8.2. Certain Notices.

                Within five Business Days after the occurrence of any Event of
         Default actually known to a Responsible Officer of the Property
         Trustee, the Property Trustee shall transmit, in the manner and to the
         extent provided in Section 10.8, notice of such Event of Default to the
         Holders and the Administrators, unless such Event of Default shall have
         been cured or waived.

                Within five Business Days after the receipt of notice of the
         Depositor's exercise of its right to defer the payment of interest on
         the Junior Subordinated Debentures pursuant to the Indenture, the
         Property Trustee shall transmit, in the manner and to the extent
         provided in Section 10.8, notice of such exercise to the Holders and
         the Administrators, unless such exercise shall have been revoked.

                SECTION 8.3. Certain Rights of Property Trustee.

                Subject to the provisions of Section 8.1:

                (a) the Property Trustee may rely and shall be fully 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, 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) any direction or act of the Depositor contemplated by this
         Trust Agreement shall be sufficiently evidenced by an Officers'
         Certificate;

                (c) the Property Trustee shall have no duty to see to any
         recording, filing or registration of any instrument (including any

         securities laws) or any re-recording, refiling or reregistration
         thereof;
<PAGE>   52
                                     - 47 -




                (d) the Property Trustee may consult with counsel of its own
         choosing (which counsel may be counsel to the Depositor or any of its
         Affiliates, and may include any of its employees) 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; 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;

                (e) 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 or direction of any of the Holders pursuant to
         this Trust Agreement, unless such Holders shall have offered to the
         Property Trustee security or indemnity satisfactory to it against the
         costs, expenses and liabilities which might be incurred by it in
         compliance with such request or direction; provided that, nothing
         contained in this Section 8.3(e) shall be taken to relieve the Property
         Trustee, upon the occurrence of an Event of Default, of its obligation
         to exercise the rights and powers vested in it by this Trust Agreement;

                (f) 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 one or more Holders, but the Property Trustee may make such
         further inquiry or investigation into such facts or matters as it may
         see fit;

                (g) the Property Trustee may execute any of the trusts or powers
         hereunder or perform any of its duties hereunder either directly or by
         or through its agents or attorneys, provided that the Property 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;

                (h) 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 (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 fully
         protected in acting in accordance with such instructions; and
<PAGE>   53

                (i) 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 any Issuer Trustee or Administrator 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 any Issuer Trustee or
         Administrator shall be construed to be a duty.

                SECTION 8.4. 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 Issuer Trust, and
         the Issuer Trustees and the Administrators do not assume any
         responsibility for their correctness. The Issuer Trustees and the
         Administrators shall not be accountable for the use or application by
         the Depositor of the proceeds of the Junior Subordinated Debentures.

                SECTION 8.5. May Hold Securities.

                Except as provided in the definition of the term "Outstanding"
         in Article I, the Administrators, any Issuer Trustee or any other agent
         of any Issuer Trustee or the Issuer Trust, in its individual or any
         other capacity, may become the owner or pledgee of Trust Securities
         and, subject to Sections 8.8 and 8.13, may otherwise deal with the
         Issuer Trust with the same rights it would have if it were not an
         Administrator, Issuer Trustee or such other agent.

                SECTION 8.6. Compensation; Indemnity; Fees.

                The Depositor, as borrower, agrees:

                (a) to pay to the Issuer 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) to reimburse the Issuer Trustees upon request for all
         reasonable expenses, disbursements and advances incurred or made
<PAGE>   54
                                     - 49 -




         by the Issuer Trustees in accordance with any provision of this Trust
         Agreement (including the reasonable compensation, expenses and
         disbursements of its agents and counsel), except any such expense,
         disbursement or advance as may be attributable to their negligence or
         willful misconduct; and

                (c) to the fullest extent permitted by applicable law, to
         indemnify and hold harmless (i) each Issuer Trustee, (ii) each
         Administrator, (iii) any Affiliate of any Issuer Trustee, (iv) any
         officer, director, shareholder, employee, representative or agent of
         any Issuer Trustee, and (v) any employee or agent of the Issuer Trust,
         (referred to herein as an "Indemnified Person") from and against any
         loss, damage, liability, tax, penalty, expense or claim of any kind or
         nature whatsoever incurred by such Indemnified Person arising out of or
         in connection with the creation, operation or dissolution of the Issuer
         Trust or any act or omission performed or omitted by such Indemnified
         Person in good faith on behalf of the Issuer Trust and in a manner such
         Indemnified Person reasonably believed to be within the scope of
         authority conferred on such Indemnified Person by this Trust Agreement,
         except that no Indemnified Person shall be entitled to be indemnified
         in respect of any loss, damage or claim incurred by such Indemnified
         Person by reason of negligence or willful misconduct with respect to
         such acts or omissions.

                The provisions of this Section 8.6 shall survive the termination
         of this Trust Agreement.

                No Issuer Trustee may claim any lien or charge on any Trust
         Property as a result of any amount due pursuant to this Section 8.6.

                The Depositor, any Administrator and any Issuer Trustee may
         engage in or possess an interest in other business ventures of any
         nature or description, independently or with others, similar or
         dissimilar to the business of the Issuer Trust, and the Issuer Trust
         and the Holders of Trust Securities shall have no rights by virtue of
         this Trust Agreement in and to such independent ventures or the income
         or profits derived therefrom, and the pursuit of any such venture, even
         if competitive with the business of the Issuer Trust, shall not be
         deemed wrongful or improper. Neither the Depositor, any Administrator,
         nor any Issuer Trustee shall be obligated to present any particular
         investment or other opportunity to the Issuer Trust even if such
         opportunity is of a character that, if presented to the Issuer Trust,
         could be taken by the Issuer Trust, and the Depositor, any
         Administrator or any Issuer Trustee shall have the right to take for
         its own account (individually or as a partner or fiduciary) or to
         recommend to others any such particular investment or other
         opportunity. Any Issuer Trustee may engage or be interested in any
         financial or other transaction with the Depositor or any Affiliate of
         the
<PAGE>   55
                                     - 50 -




         Depositor, or may act as depository for, trustee or agent for, or act
         on any committee or body of holders of, securities or other obligations
         of the Depositor or its Affiliates.

                SECTION 8.7. Corporate Property Trustee Required; Eligibility of
         Trustees and Administrators.

                (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 a national or state chartered bank and 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, the combined capital and surplus of such
         Person shall be deemed to be its combined capital and surplus as set
         forth in its most recent report of condition so published. If at any
         time the Property Trustee with respect to the Trust Securities shall
         cease to be eligible in accordance with the provisions of this Section,
         it shall resign immediately in the manner and with the effect
         hereinafter specified in this Article. At the time of appointment, the
         Property Trustee must have securities rated in one of the three highest
         rating categories by a nationally recognized statistical rating
         organization.

                (b) There shall at all times be one or more Administrators
         hereunder. Each Administrator shall be either a natural person who is
         at least 21 years of age or a legal entity that shall act through one
         or more persons authorized to bind that entity. An employee, officer or
         Affiliate of the Depositor may serve as an Administrator.

                (c) There shall at all times be a Delaware Trustee. 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 8.8. Conflicting Interests.

                (a) 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.

                (b) The Guarantee Agreement and the Indenture shall be deemed to
         be sufficiently described in this Trust Agreement for the purposes of
         clause (i) of the first proviso contained in Section 310(b) of the
         Trust Indenture Act.

                SECTION 8.9. Co-Trustees and Separate Trustee.

                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 Property
         Trustee shall have power to appoint, and upon the written request of
         the Property Trustee, the Depositor and the Administrators 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. Any co-trustee or separate trustee
         appointed pursuant to this Section 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.

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

                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:

                (a) The Trust Securities shall be executed by one or more
         Administrators, and 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 Property
         Trustees specified hereunder, shall be exercised, solely by the
         Property Trustee and not by such co-trustee or separate trustee.

                (b) 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 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.

                (c) 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, and, in case a Debenture Event of
         Default has occurred and is continuing, the Property Trustee shall have
         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.

                (d) 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.

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

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

                SECTION 8.10. Resignation and Removal; Appointment of Successor.

                No resignation or removal of any Issuer Trustee (the "Relevant
         Trustee") and no appointment of a successor Trustee pursuant to this
         Article shall become effective until the acceptance of appointment by
         the successor Trustee in accordance with the applicable requirements of
         Section 8.11.

                Subject to the immediately preceding paragraph, a Relevant
         Trustee may resign at any time by giving written notice thereof to the
         Holders. The Relevant Trustee shall appoint a successor by requesting
         from at least three Persons meeting the eligibility
<PAGE>   58
                                     - 53 -




         requirements its expenses and charges to serve as the successor Trustee
         on a form provided by the Administrators, and selecting the Person who
         agrees to the lowest expenses and charges. If the instrument of
         acceptance by the successor Trustee required by Section 8.11 shall not
         have been delivered to the Relevant Trustee within 60 days after the
         giving of such notice of resignation, the Relevant Trustee may
         petition, at the expense of the Issuer Trust, any court of competent
         jurisdiction for the appointment of a successor Trustee.

                The Property Trustee or the Delaware Trustee may be removed at
         any time by Act of the Holders of at least a Majority in Liquidation
         Amount of the Capital Securities, delivered to the Relevant Trustee (in
         its individual capacity and on behalf of the Issuer Trust) (i) for
         cause (including upon the occurrence of an Event of Default described
         in subparagraph (f) of the definition thereof with respect to the
         Relevant Trustee), or (ii) if a Debenture Event of Default shall have
         occurred and be continuing at any time.

                If any Relevant Trustee shall resign, it shall appoint its
         successor. If a resigning Relevant Trustee shall fail to appoint a
         successor, or if a Relevant Trustee shall be removed or become
         incapable of acting as Issuer Trustee, or if any vacancy shall occur in
         the office of any Issuer Trustee for any cause, the Holders of the
         Capital Securities, by Act of the Holders of record of not less than
         25% in aggregate Liquidation Amount of the Capital Securities then
         Outstanding delivered to such Relevant Trustee, shall promptly appoint
         a successor Trustee or Trustees, and such successor Issuer Trustee
         shall comply with the applicable requirements of Section 8.11. If no
         successor Trustee shall have been so appointed by the Holders of the
         Capital Securities and accepted appointment in the manner required by
         Section 8.11, any Holder, on behalf of himself and all others similarly
         situated, or any other Issuer Trustee, may petition any court in the
         State of Delaware for the appointment of a successor Trustee.

                The Property Trustee shall give notice of each resignation and
         each removal of an a Relevant Trustee and each appointment of a
         successor Trustee to all Holders in the manner provided in Section 10.8
         and shall give notice to the Depositor and to the Administrators. Each
         notice shall include the name of the Relevant Trustee and the address
         of its Corporate Trust Office if it is the Property Trustee.

                Notwithstanding the foregoing or any other provision of this
         Trust Agreement, in the event any Delaware Trustee who is a natural
         person dies or becomes, in the opinion of the Holders of the Common
         Securities, incompetent or incapacitated, the vacancy created by such
         death, incompetence or incapacity may be filled by the Property Trustee
         following the procedures regarding expenses
<PAGE>   59
                                     - 54 -




         and charges set forth above (with the successor in each case being a
         Person who satisfies the eligibility requirement for Administrators or
         Delaware Trustee, as the case may be, set forth in Section 8.7).

                SECTION 8.11. Acceptance of Appointment by Successor.

                In case of the appointment hereunder of a successor Trustee, the
         retiring Relevant Trustee and each such successor Trustee with respect
         to the Trust Securities shall execute, acknowledge and deliver an
         amendment hereto wherein each successor Trustee shall accept such
         appointment and which (a) shall contain such provisions as shall be
         necessary or desirable to transfer and confirm to, and to vest in, each
         successor Trustee all the rights, powers, trusts and duties of the
         retiring Trustee with respect to the Trust Securities and the Issuer
         Trust, and (b) shall add to or change any of the provisions of this
         Trust Agreement as shall be necessary to provide for or facilitate the
         administration of the Issuer Trust by more than one Relevant Trustee,
         it being understood that nothing herein or in such amendment shall
         constitute such Relevant co-trustees and upon the execution and
         delivery of such amendment the resignation or removal of the retiring
         Relevant Trustee shall become effective to the extent provided therein
         and each such successor Trustee, without any further act, deed or
         conveyance, shall become vested with all the rights, powers, trusts and
         duties of the Relevant Trustee; but, on request of the Issuer Trust or
         any successor Trustee such Relevant Trustee shall duly assign, transfer
         and deliver to such successor Trustee all Trust Property, all proceeds
         thereof and money held by such Relevant Trustee hereunder with respect
         to the Trust Securities and the Trust.

                Upon request of any such successor Trustee, the Issuer Trust
         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 the first or second preceding
         paragraph, as the case may be.

                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.


                SECTION 8.12. Merger, Conversion, Consolidation or Succession to
         Business.

                Any Person into which the Property Trustee or the Delaware
         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
         Person succeeding to all or substantially all the corporate
<PAGE>   60
                                     - 55 -




         trust business of such Relevant Trustee, shall be the successor of such
         Relevant Trustee hereunder, provided that such Person shall be
         otherwise qualified and eligible under this Article, without the
         execution or filing of any paper or any further act on the part of any
         of the parties hereto.

                SECTION 8.13. Preferential Collection of Claims Against
         Depositor or Issuer Trust.

                If and when the Property Trustee shall be or become a creditor
         of the Depositor (or any other obligor upon the Trust Securities), the
         Property Trustee shall be subject to the provisions of the Trust
         Indenture Act regarding the collection of claims against the Depositor
         (or any such other obligor) as is required by the Trust Indenture Act.

                SECTION 8.14. Trustee May File Proofs of Claim.

                In case of any receivership, insolvency, liquidation,
         bankruptcy, reorganization, arrangement, adjustment, composition or
         other similar judicial proceeding relative to the Issuer Trust or any
         other obligor upon the Trust Securities or the property of the Issuer
         Trust or of such other obligor, the Property Trustee (irrespective of
         whether any Distributions on the Trust Securities shall then be due and
         payable and irrespective of whether the Property Trustee shall have
         made any demand on the Issuer Trust for the payment of any past due
         Distributions) shall be entitled and empowered, to the fullest extent
         permitted by law, by intervention in such proceeding or otherwise:

                (a) to file and prove a claim for the whole amount of any
         Distributions owning and unpaid in respect of the Trust Securities and
         to file such other papers or documents as may be necessary or advisable
         in order to have the claims of the Property Trustee (including any
         claim for the reasonable compensation, expenses, disbursements and
         advances of the Property Trustee, its agents and counsel) and of the
         Holders allowed in such judicial proceeding, and

                (b) to collect and receive any monies or other property payable
         or deliverable on any such claims and to distribute the same; and any
         custodian, receiver, assignee, trustee, liquidator, sequestrator or
         other similar official in any such judicial proceeding is hereby
         authorized by each Holder to make such payments to the Property Trustee
         and, in the event the Property Trustee shall consent to the making of
         such payments directly to the Holders, to pay to the Property Trustee
         any amount due it for the reasonable compensation, expenses,
         disbursements and advances of the Property Trustee, its agents and
         counsel, and any other amounts due the Property Trustee.

                Nothing herein contained shall be deemed to authorize the
         Property Trustee to authorize or consent to or accept or adopt on
         behalf of any Holder any plan of reorganization, arrangement,
         adjustment or compensation affecting the Trust Securities or the rights
         of any Holder thereof or to authorize the Property Trustee to vote in
         respect of the claim of any Holder in any such proceeding.

         dated as of the immediately preceding December 31 with respect to:

                     (i) its eligibility under Section 8.7 or, in lieu thereof,
                if to the best of its knowledge it has continued to be eligible
                under said Section, a written statement to such effect; and

                     (ii) any change in the property and funds in its possession
                as Property Trustee since the date of its last report and any
                action taken by the Property Trustee in the performance of its
                duties hereunder which it has not previously reported and which
                in its opinion materially affects the Trust Securities.

                (b) In addition the Property Trustee shall transmit to Holders
         such reports concerning the Property Trustee and its actions under this
         Trust Agreement as may be required pursuant to the Trust Indenture Act

         in compliance with all the terms and covenants applicable to such
         Person hereunder.

                SECTION 8.17. Evidence of Compliance with Conditions Precedent.

                (b) If an Issuer Trustee ceases to hold office for any reason, a
         vacancy shall occur. The vacancy shall be filled with an Issuer Trustee
         appointed in accordance with Section 8.10.

                (c) The death, resignation, retirement, removal, bankruptcy,
         incompetence or incapacity to perform the duties of an Issuer Trustee
         shall not operate to annul the Issuer Trust.

                SECTION 8.19. Delegation of Power.

                (a) Any Administrator may, by power of attorney consistent with

                (b) The Administrators shall have power to delegate from time to
         time to such of their number the doing of such things and the execution
         of such instruments either in the name of the Issuer Trust or the names
         of the Administrators or otherwise as the Administrators may deem
         expedient, to the extent such delegation is not prohibited by
         applicable law or contrary to the provisions of this Trust Agreement.

                SECTION 8.20. Appointment of Administrators.

                (a) The Administrators (other than the initial Administrators)
         shall be appointed by the Holders of a Majority in Liquidation Amount
         of the Common Securities and all Administrators (including the initial

                                     - 58 -




         Holders of a Majority in Liquidation Amount of the Common Securities or
         may resign at any time. Each Administrator shall sign an agreement
         agreeing to comply with the terms of this Trust Agreement. If at any
         time there is no Administrator, the Property Trustee or any Holder who
         has been a Holder of Trust Securities for at least six months may
         petition any court of competent jurisdiction for the appointment of one
         or more Administrators.

                (b) Whenever a vacancy in the number of Administrators shall
         occur, until such vacancy is filled by the appointment of an
         Administrator in accordance with this Section 8.20, the Administrators
         in office, regardless of their number (and notwithstanding any other
         provision of this Agreement), shall have all the powers granted to the
         Administrators and shall discharge all the duties imposed upon the
         Administrators by this Trust Agreement.

                (c) Notwithstanding the foregoing, or any other provision of
         this Trust Agreement, in the event any Administrator or a Delaware
         Trustee who is a natural person dies or becomes, in the opinion of the
         Holders of a Majority in Liquidation Amount of the Common Securities,
         incompetent, or incapacitated, the vacancy created by such death,
         incompetence or incapacity may be filled by the remaining
         Administrators, if there were at least two of them prior to such
         vacancy, and by the Depositor, if there were not two such
         Administrators immediately prior to such vacancy (with the successor in
         each case being a Person who satisfies the eligibility requirement for
         Administrators or Delaware Trustee, as the case may be, set forth in
         Section 8.7).

                (d) Except as otherwise provided in this Trust Agreement, or by
         applicable law, any one Administrator may execute any document or
         otherwise take any action which the Administrators are authorized to
         take under this Trust Agreement.

         hereby shall terminate upon the latest to occur of the following: (a)
         the distribution by the Property Trustee to Holders of all amounts
         required to be distributed hereunder upon the liquidation of the Issuer
         Trust pursuant to Section 9.4, or upon the redemption of all of the
         Trust Securities pursuant to Section 4.2, (b) the payment of any
         expenses owed by the Issuer Trust, (c) the discharge of all
         administrative duties of the Administrators, including the performance
         of any tax reporting obligations with respect to the Issuer Trust or
         the Holders and (d) the filing of a certificate of cancellation with
         the Delaware Secretary of State pursuant to Section 3810 of the
         Delaware Business Trust Act.

                SECTION 9.4. Liquidation.

                (a) If an Early Termination Event specified in clause (a), (b)
         or (d) of Section 9.2 occurs or upon the Expiration Date, the Issuer
         Trust shall be liquidated by the Property Trustee as
<PAGE>   65
                                     - 60 -




         expeditiously as the Property Trustee determines to be possible by
         distributing, after satisfaction of liabilities to creditors of the
         Issuer Trust as provided by applicable law, to each Holder a Like
         Amount of Junior Subordinated Debentures, subject to Section 9.4(d).
         Notice of liquidation shall be given by the Property Trustee by
         first-class mail, postage prepaid, mailed not later than 15 nor more
         than 45 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 will no longer be deemed to be Outstanding and any
         Trust Securities Certificates not surrendered for exchange will be
         deemed to represent a Like Amount of Junior Subordinated Debentures;
         and

                     (iii) provide such information with respect to the
         mechanics by which Holders may exchange Trust Securities Certificates
         for Junior Subordinated Debentures, or if Section 9.4(d) applies
         receive a Liquidation Distribution, as the Administrators or the
         Property Trustee shall deem appropriate.

                (b) Except where Section 9.2(c) or 9.4(d) applies, in order to
         effect the liquidation of the Issuer Trust and distribution of the
         Junior Subordinated Debentures to Holders, the Property Trustee shall
         establish a record date for such distribution (which shall be not more
         than 30 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 Junior Subordinated Debentures in exchange
         for the Outstanding Trust Securities Certificates.

                (c) Except where Section 9.2(c) or 9.4(d) applies, after the
         Liquidation Date, (i) the Trust Securities will no longer be deemed to
         be Outstanding, (ii) the Clearing Agency for the Capital Securities or
         its nominee, as the registered holder of the Global Capital Securities
         Certificate, shall receive a registered global certificate or
         certificates representing the Junior Subordinated Debentures to be
         delivered upon such distribution with respect to Capital Securities
         held by the Clearing Agency or its nominee, and, (iii) any Trust
         Securities Certificates not held by the Clearing Agency for the Capital
         Securities or its nominee as specified in clause (ii) above will be
         deemed to represent Junior Subordinated Debentures having a principal
         amount equal to the stated Liquidation Amount of the Trust Securities
         represented thereby and bearing accrued and unpaid interest in an
         amount equal to the accumulated and unpaid Distributions on such Trust
<PAGE>   66
                                     - 61 -




         Securities until such certificates are presented to the Securities
         Registrar for transfer or reissuance.

                (d) If, notwithstanding the other provisions of this Section
         9.4, whether because of an order for dissolution entered by a court of
         competent jurisdiction or otherwise, distribution of the Junior
         Subordinated Debentures is not practical, or if any Early Termination
         Event specified in clause (c) of Section 9 occurs, the Trust Property
         shall be liquidated, and the Issuer Trust shall be dissolved by the
         Property Trustee in such manner as the Property Trustee determines. In
         such event, on the date of the dissolution of the Issuer Trust, Holders
         will be entitled to receive out of the assets of the Issuer Trust
         available for distribution to Holders, after satisfaction of
         liabilities to creditors of the Issuer Trust as provided by applicable
         law, an amount equal to the aggregate of 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, the Liquidation Distribution can be paid only in
         part because the Issuer 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 Issuer Trust on
         the Trust Securities shall be paid on a pro rata basis (based upon
         Liquidation Amounts). The Holders of the Common Securities will be
         entitled to receive Liquidation Distributions upon any such dissolution
         pro rata (determined as aforesaid) with Holders of Capital Securities,
         except that, if a Debenture Event of Default has occurred and is
         continuing, the Capital Securities shall have a priority over the
         Common Securities as provided in Section 4.3.

                SECTION 9.5. Mergers, Consolidations, Amalgamations or
         Replacements of the Issuer Trust.

                The Issuer 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 entity,
         except pursuant to this Section 9.5. At the request of the Holders of
         the Common Securities, and with the consent of the Holders of at least
         a Majority in Liquidation Amount of the Capital Securities, the Issuer
         Trust may 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, however, that (i) such successor entity either (a)
         expressly assumes all of the obligations of the Issuer Trust with
         respect to the Capital Securities or (b) substitutes for the Capital
         Securities other securities having substantially the same terms as the
         Capital Securities (the "Successor Securities") so long as the
         Successor Securities have the same priority as the Capital Securities
         with respect to distributions and payments upon
<PAGE>   67
                                     - 62 -




         liquidation, redemption and otherwise, (ii) a trustee of such successor
         entity possessing the same powers and duties as the Property Trustee is
         appointed to hold the Junior Subordinated Debentures, (iii) such
         merger, consolidation, amalgamation, replacement, conveyance, transfer
         or lease does not cause the Capital Securities (including any Successor
         Securities) to be downgraded by any nationally recognized statistical
         rating organization if the Capital Securities were rated by any
         nationally recognized statistical rating organization immediately prior
         to such merger, consolidation, amalgamation, replacement, conveyance,
         transfer or lease, (iv) such merger, consolidation, amalgamation,
         replacement, conveyance, transfer or lease does not adversely affect
         the rights, preferences and privileges of the holders of the Capital
         Securities (including any Successor Securities) in any material
         respect, (v) such successor entity has a purpose substantially
         identical to that of the Issuer Trust, (vi) prior to such merger,
         consolidation, amalgamation, replacement, conveyance, transfer or
         lease, the Issuer Trustee has received an Opinion of Counsel from
         independent counsel experienced in such matters 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 Capital Securities (including any
         Successor Securities) in any material respect, and (b) following such
         merger, consolidation, amalgamation, replacement, conveyance, transfer
         or lease, neither the Issuer Trust nor such successor entity will be
         required to register as an "investment company" under the Investment
         Company Act and (vii) the Depositor or any permitted transferee to whom
         it has transferred the Common Securities hereunder own 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 Agreement.
         Notwithstanding the foregoing, the Issuer Trust shall not, except with
         the consent of holders of 100% in Liquidation Amount of the Capital
         Securities, consolidate, amalgamate, merge with or into, or be replaced
         by or convey, transfer or lease its properties and assets substantially
         as an entirety to any other entity or permit any other entity to
         consolidate, amalgamate, merge with or into, or replace it if such
         consolidation, amalgamation, merger, replacement, conveyance, transfer
         or lease would cause the Issuer Trust or the successor entity to be
         taxable as a corporation for United States Federal income tax purposes.

                            MISCELLANEOUS PROVISIONS

                SECTION 10.1. Limitation of Rights of Holders.

                Except as set forth in Section 9.2, the death or incapacity of
         any person having an interest, beneficial or otherwise, in Trust
         Securities shall not operate to terminate this Trust Agreement, nor
         entitle the legal representatives or heirs of such person or any Holder
         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. Any
         merger or similar agreement shall be executed by the Administrators on
         behalf of the Trust.

                SECTION 10.2. Amendment.

                (a) This Trust Agreement may be amended from time to time by the
         Property Trustee and the Holders of a Majority in Liquidation Amount of
         all the Common Securities, without the consent of any Holder of the
         Capital Securities (i) to cure any ambiguity, correct or supplement any
         provision herein which may be inconsistent with any other provision
         herein, or to make any other provisions with respect to matters or
         questions arising under this Trust Agreement, provided, however, that
         such amendment shall not adversely affect in any material respect the
         interests of any Holder or (ii) to modify, eliminate or add to any
         provisions of this Trust Agreement to such extent as shall be necessary
         to ensure that the Issuer Trust will not be taxable as a corporation
         for United States Federal income tax purposes at any time that any
         Trust Securities are Outstanding or to ensure that the Issuer Trust
         will not be required to register as an investment company under the
         Investment Company Act.

                (b) Except as provided in Section 10.2(c) hereof, any provision
         of this Trust Agreement may be amended by the Property Trustee and the
         Holders of a Majority in Liquidation Amount of the Common Securities
         with (i) the consent of Holders of at least a Majority in Liquidation
         Amount of the Capital Securities and (ii) receipt by the Issuer
         Trustees of an Opinion of Counsel to the effect that such amendment or
         the exercise of any power granted to the Issuer Trustees in accordance
         with such amendment will not cause the Issuer Trust to be taxable as a
         corporation for United States federal income tax purposes or affect the
         Issuer 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
<PAGE>   69
                                     - 64 -




         Holder (such consent being obtained in accordance with Section 6.3 or
         6.6 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 Holder to institute suit for the
         enforcement of any such payment on or after such date.

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

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

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

                (g) Neither the Property Trustee nor the Delaware Trustee shall
         be required to enter into any amendment to this Trust Agreement which
         affects its own rights, duties or immunities under this Trust
         Agreement. The Property Trustee shall be entitled to receive an Opinion
         of Counsel and an Officers' Certificate stating that any amendment to
         this Trust Agreement is in compliance with this Trust Agreement.

                (h) Any amendments to this Trust Agreement shall become
         effective when notice of such amendment is given to the holders of the
         Trust Securities.

                In case any provision in this Trust Agreement or in the Trust
         Securities Certificates shall be invalid, illegal or unenforceable, the
         validity, legality and enforceability of the remaining provisions shall
         not in any way be affected or impaired thereby.

         of this Trust Agreement is required or permitted to be given or served
         to or upon the Issuer Trust, the Property Trustee, the Delaware

                Each of the Issuer Trustees, the Administrators and the
         Depositor agree for the benefit of the Holders that, until at least one
         year and one day after the Issuer Trust has been dissolved in
         accordance with Article IX, they shall not file, or join in the filing
         of, a petition against the Issuer Trust under any bankruptcy,
         insolvency, reorganization or other similar law (including, without
         limitation, the United States Bankruptcy Code) (collectively,
         "Bankruptcy Laws") or otherwise join in the commencement of any
         proceeding against the Issuer Trust under any Bankruptcy Law. In the
         event the Depositor takes action in violation of this Section 10.9, the
         Property Trustee agrees, for the benefit of Holders, that at the
         expense of the Depositor, it shall file an answer with the bankruptcy
         court or otherwise properly contest the filing of such petition by the
         Depositor against the Issuer 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 estopped and precluded therefrom and
         such other defenses, if any, as counsel for the Issuer Trustee or the
         Issuer Trust may assert. If any Issuer Trustee or Administrator takes
         action in violation of this Section 10.9, the Depositor agrees, for the
         benefit of the Holders, that at the expense of the Depositor, it shall
         file an answer with the bankruptcy court or otherwise properly contest

         commencement
<PAGE>   72
                                     - 67 -




         of such action and raise the defense that such Person has agreed in
         writing not to take such action and should be estopped and precluded
         therefrom and such other defenses, if any, as counsel for the Issuer
         Trustee or the Issuer Trust may assert. The provisions of this Section
         10.9 shall survive the termination of this Trust Agreement.

                SECTION 10.10. Trust Indenture Act; Conflict with Trust
         Indenture Act.

                (a) Trust Indenture Act; Application. (i) This Trust Agreement
         is subject to the provisions of the Trust Indenture Act that are
         required to be a part of this Trust Agreement and shall, to the extent
         applicable, be governed by such provisions; (ii) if and to the extent
         that any provision of this Trust Agreement limits, qualifies or
         conflicts with the duties imposed by Sections 310 to 317, inclusive, of
         the Trust Indenture Act, such imposed duties shall control; (iii) for
         purposes of this Trust Agreement, the Property Trustee, to the extent
         permitted by applicable law and/or the rules and regulations of the
         Commission, shall be the only Issuer Trustee which is a trustee for the
         purposes of the Trust Indenture Act; and (iv) the application of the

covenants shall be read into this Guarantee Agreement against the Guarantee
Trustee. If an Event of Default has occurred (that has not been cured or waived
pursuant to Section 2.6), the Guarantee Trustee shall exercise such of the
rights and powers vested in it by this Guarantee Agreement, 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 Guarantee Agreement shall be construed
to relieve the Guarantee Trustee from liability for its own negligent action,

occurred:

                         (A)  the duties and obligations of the Guarantee 
Trustee shall be determined solely by the express provisions of this Guarantee
Agreement (including pursuant to Section 2.1), and the Guarantee Trustee shall
not be liable except for the performance of such duties and obligations as are
specifically set forth in this Guarantee Agreement (including pursuant to
Section 2.1); and

                         (B)  in the absence of bad faith on the part of the

of the statements and the correctness of the opinions expressed therein, upon

the same to determine whether or not they conform to the requirements of this
Guarantee Agreement;

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

                   (iii) The Guarantee Trustee shall not be liable with respect
to any action taken or omitted to be taken by it in good faith in accordance

the 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 Guarantee Trustee shall have
reasonable grounds for believing that the repayment of such funds or liability
is not assured to it under the terms of this Guarantee Agreement or adequate
indemnity against such risk or liability is not reasonably assured to it.

                                     - 10 -


the absence of bad faith on its part, request and conclusively rely upon an
Officers' Certificate which, upon receipt of such request from the Guarantee
Trustee, shall be promptly delivered by the Guarantor.

                   (iv)   The Guarantee Trustee may consult with legal counsel,
and the advice or written opinion of such legal counsel with respect to legal
matters shall be full and complete authorization and protection in respect of
any action taken, suffered or omitted to be taken by it hereunder in good faith
and in accordance with such advice or opinion. Such legal counsel may be legal
counsel to the Guarantor or any of its Affiliates and may be one of its

incurred by it in complying with such request or direction, including such
reasonable advances as may be requested by the Guarantee Trustee.

powers hereunder or perform any duties hereunder either directly or by or
through its agents or attorneys, and the Guarantee Trustee shall not be
responsible for any negligence or wilful misconduct on the part of any such
agent or attorney appointed with due care by it hereunder.

                   (viii) Whenever in the administration of this Guarantee 
Agreement the Guarantee Trustee shall deem it desirable to receive instructions
with respect to enforcing any remedy or right or taking any other action
hereunder, the Guarantee Trustee (A) may request instructions from the Holders,

<PAGE>   15

until such instructions are received and (C) shall be fully protected in acting
in accordance with such instructions.

              (b)  No provision of this Guarantee Agreement shall be deemed to

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 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 Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

hold it harmless against, any loss, liability or expense incurred without

arising out of or in connection with the acceptance or administration of this
Guarantee Agreement, including the costs and expenses of defending itself

         SECTION 4.1. Guarantee Trustee; Eligibility.

              (a)  There shall at all times be a Guarantee Trustee which shall:

                   (i)   not be an Affiliate of the Guarantor; and

                   (ii)  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, and shall be a corporation meeting the requirements of Section
310(a) of the Trust Indenture Act. If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of the
<PAGE>   16
                                     - 12 -


supervising or examining authority, then, for the purposes of this Section and
to the extent permitted by the Trust Indenture Act, 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.

              (b) If at any time the Guarantee Trustee shall cease to be
eligible to so act under Section 4.1(a), the Guarantee Trustee shall immediately
resign in the manner and with the effect set out in Section 4.2(b).

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

         SECTION 4.2. Appointment, Removal and Resignation of the 
                      Guarantee Trustee.

              (a) No resignation or removal of the Guarantee Trustee and no
appointment of a Successor Guarantee Trustee pursuant to this Article shall
become effective until the acceptance of appointment by the Successor Guarantee
Trustee by written instrument executed by the Successor Guarantee Trustee and
delivered to the Holders and the Guarantee Trustee.

              (b) Subject to the immediately preceding paragraph, a Guarantee
Trustee may resign at any time by giving written notice thereof to the Holders.
The Guarantee Trustee shall appoint a successor by requesting from at least
three Persons meeting the eligibility requirements such Person's expenses and
charges to serve as the Guarantee Trustee, and selecting the Person who agrees
to the lowest expenses and charges. If the instrument of acceptance by the
Successor Guarantee Trustee shall not have been delivered to the Guarantee
Trustee within 60 days after the giving of such notice of resignation, the
Guarantee Trustee may petition, at the expense of the Guarantor, any court of
competent jurisdiction for the appointment of a Successor Guarantee Trustee.

              (c) The Guarantee Trustee may be removed for cause at any time by
Act (within the meaning of Section 6.8 of the Trust Agreement) of the Holders of
at least a Majority in Liquidation Amount of the Capital Securities, delivered
to the Guarantee Trustee.

              (d) If a resigning Guarantee Trustee shall fail to appoint a
successor, or if a Guarantee Trustee shall be removed or become incapable of
acting as Guarantee Trustee, or if any vacancy shall occur in the office of any
Guarantee Trustee for any cause, the Holders of the Capital Securities, by Act
of the Holders of

record of not less than 25% in aggregate Liquidation Amount of the Capital
Securities then outstanding delivered to such Guarantee Trustee, shall promptly
appoint a successor Guarantee Trustee. If no Successor Guarantee Trustee shall
have been so appointed by the Holders of the Capital Securities and such
appointment accepted by the Successor Guarantee Trustee, any Holder, on behalf
of himself and all others similarly situated, may petition any court of
competent jurisdiction for the appointment of a Successor Guarantee Trustee.


                              ARTICLE V. GUARANTEE

         SECTION 5.1. Guarantee.

         The Guarantor irrevocably and unconditionally agrees to pay in full on
a subordinated basis as set forth in Section 6.1 hereof to the Holders the
Guarantee Payments (without duplication of amounts theretofore paid by or on
behalf of the Issuer Trust), as and when due, regardless of any defense, right
of set-off or counterclaim which the Issuer Trust may have or assert, except the
defense of payment. The Guarantor's obligation to make a Guarantee Payment may
be satisfied by direct payment of the required amounts by the Guarantor to the
Holders or by causing the Issuer Trust to pay such amounts to the Holders. The
Guarantor shall give prompt written notice to the Guarantee Trustee in the event
it makes any direct payment hereunder.

         SECTION 5.2. Waiver of Notice and Demand.

         The Guarantor hereby waives notice of acceptance of the Guarantee
Agreement and of any liability to which it applies or may apply, presentment,
demand for payment, any right to require a proceeding first against the
Guarantee Trustee, the Issuer Trust or any other Person before proceeding
against the Guarantor, protest, notice of nonpayment, notice of dishonor, notice
of redemption and all other notices and demands.

         SECTION 5.3. Obligations Not Affected.

         The obligations, covenants, agreements and duties of the Guarantor
under this Guarantee Agreement shall in no way be affected or impaired by reason
of the happening from time to time of any of the following:

the performance or observance by the Issuer Trust of any express or implied
agreement, covenant, term or condition relating to the Capital Securities to be
performed or observed by the Issuer Trust;
<PAGE>   18
                                     - 14 -


              (b) the extension of time for the payment by the Issuer Trust of
all or any portion of the Distributions (other than an extension of time for
payment of Distributions that results from the extension of any interest payment
period on the Junior Subordinated Debentures as so provided in the Indenture),
Redemption Price, Liquidation Distribution or any other sums payable under the
terms of the Capital Securities or the extension of time for the performance of
any other obligation under, arising out of, or in connection with, the Capital
Securities;

              (c) any failure, omission, delay or lack of diligence on the part
of the Holders to enforce, assert or exercise any right, privilege, power or
remedy conferred on the Holders pursuant to the terms of the Capital Securities,
or any action on the part of the Issuer Trust granting indulgence or extension
of any kind;

              (d) the voluntary or involuntary liquidation, dissolution, sale of
any collateral, receivership, insolvency, bankruptcy, assignment for the benefit
of creditors, reorganization, arrangement, composition or readjustment of debt
of, or other similar proceedings affecting, the Issuer Trust or any of the
assets of the Issuer Trust;

              (e) any invalidity of, or defect or deficiency in, the Capital
Securities;

              (f) the settlement or compromise of any obligation guaranteed
hereby or hereby incurred; or

              (g) any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a guarantor (other than
payment of the underlying obligation), it being the intent of this Section 5.3
that the obligations of the Guarantor hereunder shall be absolute and
unconditional under any and all circumstances.

         There shall be no obligation of the Holders to give notice to, or
obtain the consent of, the Guarantor with respect to the happening of any of the
foregoing.

         SECTION 5.4. Rights of Holders.

         The Guarantor expressly acknowledges that: (i) this Guarantee Agreement
will be deposited with the Guarantee Trustee to be held for the benefit of the
Holders; (ii) the Guarantee Trustee has the right to enforce this Guarantee
Agreement on behalf of the Holders; (iii) the Holders of a Majority in

                                     - 15 -


Guarantee Agreement or exercising any trust or power conferred upon the
Guarantee Trustee under this Guarantee Agreement; and (iv) any Holder may
institute a legal proceeding directly against the Guarantor to enforce its
rights under this Guarantee Agreement, without first instituting a legal
proceeding against the Guarantee Trustee, the Issuer Trust or any other Person.

         SECTION 5.5. Guarantee of Payment.

         This Guarantee Agreement creates a guarantee of payment and not of
collection. This Guarantee Agreement will not be discharged except by payment of
the Guarantee Payments in full (without duplication of amounts theretofore paid
by the Issuer Trust) or upon the distribution of Junior Subordinated Debentures
to Holders as provided in the Trust Agreement.

         SECTION 5.6. Subrogation.

         The Guarantor shall be subrogated to all rights (if any) of the Holders
against the Issuer Trust in respect of any amounts paid to the Holders by the
Guarantor under this Guarantee Agreement; provided, however, that the Guarantor
shall not (except to the extent required by mandatory provisions of law) be
entitled to enforce or exercise any rights which it may acquire by way of
subrogation or any indemnity, reimbursement or other agreement, in all cases as
a result of payment under this Guarantee Agreement, at the time of any such
payment, any amounts are due and unpaid under this Guarantee Agreement. If any
amount shall be paid to the Guarantor in violation of the preceding sentence,
the Guarantor agrees to hold such amount in trust for the Holders and to pay
over such amount to the Holders.

         SECTION 5.7. Independent Obligations.

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer Trust with respect to the Capital
Securities and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Guarantee
Agreement notwithstanding the occurrence of any event referred to in subsections
(a) through (g), inclusive, of Section 5.3 hereof.


                     ARTICLE VI. COVENANTS AND SUBORDINATION

         SECTION 6.1. Subordination.

         This Guarantee Agreement will constitute an unsecured obligation of the
Guarantor and will rank subordinate and junior in right of payment to all Senior
Indebtedness of the Guarantor to the extent and in the manner set forth in the
Indenture with
<PAGE>   20
                                     - 16 -


respect to the Junior Subordinated Debentures, and the provisions of Article
XIII of the Indenture will apply, mutatis mutandis, to the obligations of the
Guarantor hereunder. The obligations of the Guarantor hereunder do not
constitute Senior Indebtedness of the Guarantor.

         SECTION 6.2. Pari Passu Guarantees.

         The obligations of the Guarantor under this Guarantee Agreement shall
rank pari passu with any similar guarantee agreements issued by the Guarantor on
behalf of the holders of preferred or capital securities issued by the Issuer
Trust and with any other security, guarantee or other obligation that is
expressly stated to rank pari passu with the obligations of the Guarantor under
this Guarantee Agreement.


                            ARTICLE VII. TERMINATION

         SECTION 7.1. Termination.

         This Guarantee Agreement shall terminate and be of no further force and
effect upon (i) full payment of the Redemption Price of all Capital Securities,
(ii) the distribution of Junior Subordinated Debentures to the Holders in
exchange for all of the Capital Securities or (iii) full payment of the amounts
payable in accordance with Article IX of the Trust Agreement upon liquidation of
the Issuer Trust. Notwithstanding the foregoing, this Guarantee Agreement will
continue to be effective or will be reinstated, as the case may be, if at any
time any Holder is required to repay any sums paid with respect to Capital
Securities or this Guarantee Agreement.


                           ARTICLE VIII. MISCELLANEOUS

         SECTION 8.1. Successors and Assigns.

         All guarantees and agreements contained in this Guarantee Agreement
shall bind the successors, assigns, receivers, trustees and representatives of
the Guarantor and shall inure to the benefit of the Holders of the Capital
Securities then outstanding. Except in connection with a consolidation, merger
or sale involving the Guarantor that is permitted under Article VIII of the
Indenture and pursuant to which the assignee agrees in writing to perform the
Guarantor's obligations hereunder, the Guarantor shall not assign its
obligations hereunder, and any purported assignment that is not in accordance
with these provisions shall be void.

be required), this Guarantee Agreement may only be amended with the prior
approval of the Holders of not less than a Majority in Liquidation Amount of the
Capital Securities. The provisions of Article VI of the Trust Agreement
