                                  THE COMPANY


        St. Paul Bancorp is the holding company for St. Paul Federal Bank For
   Savings (the "Bank"), the largest independent savings institution in the
   State of Illinois.  The Company, either directly or through the Bank, also
   owns financial services subsidiaries involved in discount brokerage, real
   estate development, insurance and annuity product sales.  For the nine months
   ended September 30, 1996, the Company had consolidated net income of $15.4
   million, after a pre-tax charge of $21.0 million in connection with a one-
   time special assessment on the Bank's deposits to recapitalize the Savings
   Association Insurance Fund of the Federal Deposit Insurance Corporation
   ("FDIC").  At September 30, 1996, the Company had $4.3 billion in assets and
   $371.6 million in stockholders' equity.

        The Bank is a FDIC insured retail depository institution that operates
   through 52 branches in the Chicago metropolitan area.  The Bank's branch
   network includes 35 free-standing offices and 17 banking offices located in
   Omni(R) and Cub(R) superstores.  The Bank's expansion of its branch network
   through "in-store" facilities provides access to a larger retail customer
   base through offices which have relatively lower overhead.  The Bank has also
   recently expanded its automated teller machine ("ATM") network to 460
   machines by installing 261 ATMs in White Hen Pantry(R) convenience stores in
   the eight county Chicago area, including stores in Northwest Indiana.  In
   addition, the Bank opened a telephone banking facility in 1995 to support
   customer service, as well as handle inquiries and loan applications.

        The Bank services approximately 179,000 checking accounts, offering a
   number of options, including special sports checking programs such as Chicago
   Bulls Checking, Chicago Cubs Checking and Chicago Bears Checking.  The Bank
   also offers a variety of savings, money market and certificate of deposit
   products.  At September 30, 1996, the Bank had total deposits of $3.3
   billion.

        The Bank's interest earning assets primarily consist of loans secured by
   mortgages on residential real estate, securities and, to a lesser extent,
   consumer and commercial real estate loans.  At September 30, 1996, the Bank's
   mortgage loan portfolio included $2.0 billion of 1-4 family residential
   mortgage loans, $961.4 million of multifamily residential mortgage loans,
   $54.4 million of commercial and other mortgage loans, and $20.0 million in
   consumer loans.  At September 30, 1996, the Bank also held $799.2 million of
   mortgage-backed securities ("MBS"), and invested in government and other
   investment grade, liquid securities.

        The Bank's 1-4 family residential mortgage products are originated
   through its retail banking offices and telephone banking facility, as well as
   a correspondent loan program in the Chicago metropolitan area and midwestern
   states (including Wisconsin, Indiana, Michigan and Ohio).  In the first nine
   months of 1996, the Bank (either directly or through correspondents)
   originated over $220.0 million of 1-4 family residential mortgage loans.  In
   addition to such originations, in the first nine months of 1996 the Bank
   purchased $435.1 million of 1-4 family adjustable rate mortgage loans secured
   by 1-4 family residential real estate located throughout the U.S.

        The Bank also originates loans secured by apartment buildings in
   Illinois, Wisconsin, Indiana, Minnesota and Ohio, using the same underwriting
   standards throughout the area.  At September 30, 1996, the Bank's portfolio
   of Midwest apartment building loans totaled $111.5 million or 3.7% of the
   loan portfolio.

        The Bank offers a variety of consumer loan products through its retail
   banking offices, telemarketing and its telephone banking facility, including
   home equity loans, secured lines of credit, education and automobile loans.
   The Bank has entered into agreements to sell consumer loans that do not meet
   its underwriting standards to third parties, rather than retaining them.

        At September 30, 1996, the Bank's loan portfolio included $909.1 million
   of loans originated prior to 1990 on a nationwide basis secured by
   multifamily real estate and, to a lesser extent, commercial real estate.
   Approximately 38% of this portfolio is scheduled to mature between the third
   quarter of 1996 and the end of

                                      -3-
<PAGE>
 
   1998.  The Bank intends to refinance a large portion of these loans,
   depending upon the credit characteristics.  The Bank was able to refinance
   over 70% of the loans in this portfolio which matured in the first nine
   months of 1996.  The remainder of these loans was paid off or liquidated out
   of foreclosed real estate.

        Subsidiaries of the Bank or the Company include Investment Network,
   Inc., a discount broker with over $3.8 million in commission revenue for the
   nine months ended September 30, 1996; Annuity Network, Inc., which offers
   customers fixed rate annuity products; and SPF Insurance Agency, Inc., which
   offers homeowners, auto, life and disability insurance.  The Company's real
   estate development subsidiary, St. Paul Financial Development Corporation,
   engages in single family real estate development and, to some extent,
   commercial real estate construction financing.

        The principal offices of the Company are located at 6700 West North
   Avenue, Chicago, Illinois  60707, telephone (773) 622-5000.

(a)  Includes the operations of Elm Financial Services from the acquisition date
     of February 23, 1993.
(b)  The Company has in place a stock repurchase program which runs until July
     15, 1997. Of the 1.125 million shares of common stock authorized to be
     repurchased under the program (representing approximately 5% of the
     outstanding shares), none had been purchased as of September 30, 1996 and
     168,750 shares had been purchased as of January 15, 1997 at an average
     price of $22.46 per share. There can be no assurance that any additional
     shares authorized to be repurchased under the program will be repurchased,
     nor can there be any assurance as to the cost of any additional shares
     which may be repurchased in future periods.
(c)  Restated for a five-for-four stock split effective on January 14, 1997
     (with a record date of December 31, 1996).  Also includes a restatement for
     a three-for-two stock split on January 4, 1994.
(d)  Without the one-time SAIF recapitalization charge, net income would have
     been $29,303,000 or $1.23 per primary share for the first nine months of
     1996.
(e)  Subsequent to the five-for-four stock split, the Company's quarterly cash
     dividend rate has been maintained at $0.12 per share, effective with the
     dividend declared on January 15, 1997.
(f)  Annualized where applicable.
(g)  Without the one-time SAIF recapitalization charge, return on average assets
     would have been 0.93% and return on average stockholders' equity would have
     been 10.17% for the nine months ended September 30, 1996.
(h)  On a pro forma basis, giving effect to the $100,000,000 principal amount
     of Notes offered hereby and the redemption of the Company's outstanding
     8.25% Subordinated Notes due 2000, the ratio of earnings to fixed charges
     for the nine months ended September 30, 1996 would be 1.87 excluding
     interest on deposits and 1.18 including interest on deposits. See
     "Capitalization".

                              RECENT DEVELOPMENTS
                              ------------------- 

The Company's net income for the fourth quarter of 1996 was $10.9 million, 
which represents an increase of 17% over the $9.3 million during the same 
quarter in 1995. Earnings per share increased over 20% to 46 cents for the 
current quarter, versus 38 cents per share for the same period a year ago./1/ 
Net interest income for the fourth quarter of 1996 rose 8% to $31.9 million, 
compared to $29.4 million in the same quarter a year ago. Also during the fourth
quarter of 1996, other operating income rose 6% to $9.1 million, compared to 
$8.6 million during the same quarter in 1995. These increases were partially 
offset by a $1.7 million, or 7%, increase in operating expenses.

     Net income for 1996 was $26.3 million, or $1.10 per share. Operating 
results for the year included a $21.0 million pretax third quarter charge for a 
one-time assessment to recapitalize the Savings Association Insurance Fund 
("SAIF"). Excluding the SAIF charge, net income would have been $40.2 million, 
or $1.69 per share, which represents a 10% increase over 1995 net income of 
$36.4 million, or $1.49 per share. The improvement in operating earnings for the
year reflects the results of the Company's strategy to increase earning assets 
and to continue to increase other income. The Company intends to continue this 
strategy in 1997, as well as seek opportunities to expand its franchise in the 
Chicago area by opening additional in-store or storefront branches.

     For the year 1996, the return on average assets was 0.62% (0.95% without 
the SAIF charge) versus 0.90% for the year 1995 and the return on average equity
was 6.85% (10.48% without the SAIF charge) versus 9.86% for the year 1995. Also,
at December 31, 1996, stockholders' equity was equivalent to 8.91% of total
assets or $17.04 per share.

     Total assets at December 31, 1996 were $4.4 billion which represents an 
increase of almost 6% over the $4.1 billion as of December 31, 1995. The 
increase in assets during 1996 was primarily in mortgage loans receivable which 
increased by $92.0 million and mortgage-backed securities which increased by 
$187.6 million. These increases have been funded primarily by a decrease in 
investment securities of $27.6 million, an increase in deposits of $105.2 
million and an increase in borrowings of $119.8 million. During 1996, the 
Company purchased over $600.0 million of 1-4 family adjustable-rate mortgage 
loans, of which $190.0 million were purchased in the fourth quarter.

     Net interest income for 1996 was $124.7 million, an increase of $8.1 
million or 7% over the $116.6 million reported during 1995. The Company reported
an increase in both interest income and interest expense due to the increases in
both interest-earning assets and interest-bearing liabilities. The Company's 
average earning assets grew 4.6% or $178.5 million, to $4.1 billion for 1996 
from $3.9 billion for 1995. The Company's average interest-bearing liabilities 
grew by $161.9 million to $3.8 billion, an increase of 4.5%. At December 31, 
1996 the yield on earning assets increased to 7.36% from 7.28% at December 31, 
1995. In comparison at December 31, 1996 the rate on interest-bearing 
liabilities increased to 4.58% from 4.56%. As a result, the net interest spread 
(equal to the yield on earning assets less the rate on interest-bearing 
liabilities) increased to 2.78% at December 31, 1996 from 2.72% at December 31, 
1995. The net interest margin (net yield on average earning assets) was 3.07% 
in 1996, compared to 3.01% during 1995.

     Other income rose 6% to $35.7 million for 1996, compared to $33.7 million 
during the previous year. The increase in revenues for the year resulted from 
higher revenues from discount brokerage operations and ATMs--including the 
installation of 261 ATMs in White Hen Pantries during 1996.

     Other operating expenses totaled $117.8 million during 1996, including the 
$21.0 million SAIF charge recorded during the third quarter of the year. 
Without the one-time SAIF charge, other operating expenses would have been $96.8
million, or 7% higher than the $90.2 million of G&A expenses during 1995. 
Advertising and occupancy expenses showed the greatest percentage increases for 
the year. The benefits from the reduction in deposit insurance premiums 
resulting from the SAIF recapitalization will be realized starting in the first 
quarter of 1997.

     The Company reported nonperforming assets at December 31, 1996 of $12.5 
million or 0.29% of total assets, the lowest level since the Company went public
in 1987. This compares with nonperforming assets of $20.6 million (0.48% of 
total assets) at September 30, 1996 and $29.2 million (or 0.71% of total assets)
at December 31, 1995. Net loan and REO charge-offs were $7.0 million during 
1996, compared to $6.3 million during 1995. At December 31, 1996, the general 
valuation allowance for loans was $30.7 million, or 1.09% of total loans 
receivable and 322% of nonperforming loans.

     The Company's leverage ratio, Tier 1 capital ratio, and total risk-based 
capital ratio were 8.80%, 16.02% and 17.27%, respectively, at December 31, 1996,
compared to 8.95%, 16.18% and 17.47% respectively, at December 31, 1995.

                          CERTAIN REGULATORY MATTERS

   GENERAL

        The Company is a "savings and loan holding company" registered with the
   Office of Thrift Supervision (the "OTS") and, as such, the Company is subject
   to OTS regulations, examinations, supervision and reporting.  The Bank is
   subject to examination and comprehensive regulation by the OTS.  The Bank's
   deposits are insured by the Savings Association Insurance Fund ("SAIF") of
   the FDIC and the Bank is subject to regulation by the FDIC and by the Board
   of Governors of the Federal Reserve System with respect to reserves
   maintained against deposits and certain other matters.

   RESTRICTIONS ON CAPITAL DISTRIBUTIONS AND TRANSACTIONS BY THE BANK WITH
   AFFILIATES

        The principal source of funds for the Company's payments of principal
   and interest on the Notes (and cash dividends on its common stock) will be
   dividends from the Bank and the Company's other subsidiaries.  In addition,
   at September 30, 1996, the Company had $22.8 million in cash and cash
   equivalents.

        The OTS has adopted a regulation governing capital distributions by
   savings institutions, which include cash dividends, stock redemptions or
   repurchases, cash-out mergers, interest payments on certain convertible debt
   and other transactions charged to the capital account of a savings
   institution.  Generally, the regulation creates a safe harbor for specified
   levels of capital distributions from institutions meeting at least their
   minimum capital requirements, so long as such institutions notify the OTS and
   receive no objection to the distribution from the OTS.  Institutions that do
   not qualify for the safe harbor are required to obtain prior OTS approval
   before making any capital distributions.  These regulations do not apply to
   distributions from direct subsidiaries of the Company, such as Annuity
   Network, Inc. and St. Paul Financial Development Corporation.

        The Bank is currently a "Tier 1" institution under the OTS regulation
   and, under the safe harbor, may make capital distributions of up to the
   greater of 100% of its net income during a calendar year plus the amount that
   would reduce by one-half its surplus capital ratio (the percentage by which
   the institution's capital-to-assets ratio exceeds the ratio of its fully
   phased-in capital requirements to its assets) at the beginning of the
   calendar year, or 75% of its net income over the most recent four quarter
   period.

        The OTS has proposed to amend its regulation on capital distributions
   such that the Bank would no longer have to obtain approval from the OTS in
   order to make a distribution in excess of the safe harbor amount, unless such
   distribution would cause the Bank to fail to meet the OTS's prompt corrective
   action ("PCA") capital standards for a "well-capitalized" institution.  The
   OTS would, however, continue to receive prior notice of a distribution and
   would retain the authority to prohibit any capital distribution upon a
   determination that the making of such distribution would constitute an unsafe
   or unsound practice.  The Company does not anticipate that adoption of the
   proposed regulation would have a material impact on the Bank's ability to
   make distributions of capital.

        In addition to regulation of capital distributions, there are various
   statutory and regulatory limitations on the extent to which the Bank can
   finance or otherwise transfer funds to the Company or its non-banking
   subsidiaries, whether in the form of loans, extensions of credit, investments
   or asset purchases.  Such transfers by the Bank to the Company or any non-
   banking subsidiary are generally limited to 10% of the Bank's capital and
   surplus and, with respect to the Company and all such non-banking
   subsidiaries, to an aggregate of 20% of the Bank's capital and surplus.
   Furthermore, loans and extensions of credit are required to be secured in
   specified amounts and are required to be on terms and conditions consistent
   with safe and sound banking practices.  The OTS Director may further restrict
   these transactions in the interest of safety and soundness.

                                      -9-

CAPITAL REGULATIONS

     The OTS has prescribed capital regulations (the "Capital Regulations") that
establish three capital requirements which must be met by the Bank -- a "core
capital requirement," a "tangible capital requirement" and a "risk-based capital
requirement." The Capital Regulations require thrift institutions to maintain
"core" capital of at least 3% of adjusted total assets, "tangible" capital of at
least 1.5% of adjusted total assets, and "risk-based" capital of at least 8% of
risk-weighted assets. Capital standards for thrifts must be no less stringent
than the capital standards applicable to national banks (a leverage ratio of 4%
of adjusted total assets). Therefore, the Bank believes that it is required to
maintain core capital of at least 4% of adjusted total assets. The Bank exceeded
all of the capital requirements at September 30, 1996.

     The OTS has also adopted separate PCA regulations that call for the OTS to
enforce certain restrictions on savings institutions that are classified as
undercapitalized. As of September 30, 1996, the Bank met the requirements of the
OTS to be categorized for PCA purposes as a "well-capitalized institution." An
institution's capital category, however, is determined solely for regulatory
purposes and may not constitute an accurate representation of the institution's
financial condition or prospects.

     Under the Federal Deposit Insurance Corporation Improvement Act of 1991,
the OTS recently published regulations to ensure that its risk-based capital
standards take adequate account of concentration of credit risk, risk from
nontraditional activities, and actual performance and expected risk of loss on
multifamily mortgages. These rules allow the regulators to impose, on a case-by-
case basis, an additional capital requirement above the current requirements
where an institution has significant concentration of credit risk or risks from
nontraditional activities. The Bank is currently not subject to any additional
capital requirements under these regulations.

     The OTS may establish capital requirements higher than the generally
applicable minimum for a particular savings institution if the OTS determines
the institution's capital was or may become inadequate in view of its particular
circumstances. Individual minimum capital requirements may be appropriate where
the savings institution is receiving special supervisory attention, has a high
degree of exposure to interest rate risk, or poses safety or soundness concerns.
The Bank has no such requirements.

RECENT LEGISLATION

     To mitigate the disparity and any competitive disadvantage due to disparate
deposit insurance premium schedules between the Bank Insurance Fund ("BIF") and
SAIF, on September 30, 1996, President Clinton signed legislation to
recapitalize the SAIF. This legislation required members of SAIF, such as the
Bank, to pay a one-time special assessment of 65.7 cents per $100 of deposits as
of March 31, 1995, to fully capitalize SAIF to the desired levels. Beginning in
1997, annual SAIF insurance premiums will drop to about 6.4 cents per $100 of
deposits, while BIF premiums will be 1.3 cents per $100 of deposits. The
Company's third quarter operating results include a $21.0 million pre-tax charge
for the Bank's share of the special assessment. As a result, management expects
future SAIF insurance premiums to be reduced by $5.5 million annually, based
upon current deposit levels.

     Recent legislation also eliminated the availability of the percentage-of-
taxable income bad debt method for federal income tax purposes. The Bank will be
required to use the specific charge-off method in the future. Previously, the
Bank had been able to use either the percentage-of-taxable income method or the
specific charge-off method. The legislation also eliminated the recapture of the
base year tax reserve (i.e., tax bad debt reserves established before 1988) if
the Bank were to fail the qualified thrift lender test. As a result of the
legislation, the base year tax reserve becomes subject to recapture if the Bank
ceased to be a bank or made distributions of the tax bad debt reserves to
shareholders. The legislation also requires the Bank to recapture, into taxable
income, $547,000 of additions made to the tax bad debt reserve since 1988. This
recapture will occur over a six year period beginning in 1996, but can be
delayed for two years if the Bank meets recently developed loan origination
tests.

                                USE OF PROCEEDS

        The net proceeds from the sale of the Notes will be used to repurchase
   or redeem, at par, all of the Company's outstanding 8.25% Subordinated Notes
   due 2000 ("Subordinated Notes"), the outstanding principal balance of which
   is approximately $34.5 million.  The Company expects to repurchase or redeem
   the Subordinated Notes within 60 days after the sale of the Notes.  The
   remainder of the net proceeds will be added to the general funds of the
   Company to be available for any general corporate purpose.

                              DESCRIPTION OF NOTES

        The following sets forth certain general terms and provisions of the
   Notes.  The Notes are to be issued under an indenture (the "Indenture")
   between the Company and Harris Trust and Savings Bank, as trustee (the
   "Trustee").  A copy of the form of the Indenture is filed as an exhibit to
   the Registration Statement of which this Prospectus is a part.  See
   "Available Information."  The following summaries of certain provisions of
   the Notes and the Indenture do not purport to be complete and are subject to,
   and are qualified in their entirety by reference to all of the provisions of
   the Indenture, including the definition therein of certain terms, and the
   actual provisions of the Notes.  Capitalized terms used herein have the
   meanings attributed to them in the Indenture (unless otherwise defined
   herein).  Section references made herein refer to sections of the Indenture.

   GENERAL

        The Notes will constitute a single series of debt securities ("Debt
   Securities") to be issued under the Indenture.  The Notes will be limited to
   $100,000,000 in aggregate principal amount, will mature on _________, 2004
   and will be unsecured, unsubordinated obligations of the Company.

        The Notes will bear interest at the rate set forth on the cover page of
   this Prospectus.  Interest on the Notes will be payable semi-annually on each
   _______________ and ________________ (each an "Interest Payment Date"),
   commencing ________________, 1997.  Interest payable on each Interest Payment
   Date will include interest accrued from _______________, 199_ or from the
   most recent Interest Payment Date to which interest has been paid or duly
   provided for.  Interest payable on any Interest Payment Date will be payable
   to the person in whose name a Note (or any predecessor Note) is registered at
   the close of business on the _______________ or _______________, as the case
   may be, next preceding such Interest Payment Date.  Principal of and interest
   on the Notes will be payable at the office or agency of the Company
   maintained for such purpose in Chicago, Illinois, which initially will be the
   office of the Paying Agent, provided that payment of interest may be made
   (subject to collection), at the option of the Company, by check mailed to the
   person entitled thereto.  Interest shall be computed on the basis of a 360-
   day year comprised of twelve 30-day months.

        The Notes will be issued only in fully registered form, without coupons,
   in denominations of $1,000 and any integral multiple thereof.  No service
   charge will be made for any registration of transfer or exchange of Notes,
   except in certain circumstances for any tax or other governmental charge that
   may be imposed in connection therewith.  (Sections 3.1, 3.2 and 3.5)

   RANKING

        The Notes will be general unsecured obligations and will rank pari passu
   with all other unsecured and unsubordinated senior indebtedness of the
   Company.

        The Company conducts its operations primarily through its subsidiaries.
   The rights of the Company and its creditors, including the holders of the
   Notes offered hereby, to participate in the assets of any subsidiary upon
   such subsidiary's liquidation or reorganization or otherwise will be subject
   to the prior claims of the subsidiary's depositors and creditors, except to
   the extent that the Company may itself be a creditor with recognized claims
   against the subsidiary.

   OPTIONAL REDEMPTION

        The Notes will not be redeemable prior to maturity.  The Company may
   purchase Notes in the open market, by tender or by contract.  Notes so
   purchased may be held, resold or surrendered to the Trustee for cancellation.
   If applicable, the Company will comply with the requirements of Rule 14e-1
   under the Exchange Act and other securities laws and regulations in
   connection with any such purchase.

   SINKING FUND

        There will be no sinking fund payments for the Notes.

   CERTAIN COVENANTS

        The Indenture contains, among others, the following covenants:

        Limitation on Sale or Issuance of Capital Stock or Convertible
   Securities of, and Merger or Sale of Assets by, a Bank.  The Company will
   not: (i) nor will it permit any Bank to, issue, sell, transfer, assign,
   pledge or otherwise dispose of any shares of capital stock of any class of a
   Bank or any securities convertible or exchangeable into shares of capital
   stock of any class of a Bank unless after giving effect to such transaction
   and to shares issuable upon conversion or exchange of outstanding securities
   convertible or exchangeable into such capital stock (including such
   securities, if any, which may be the subject of such transaction), at least
   80% of the outstanding shares of capital stock of each class of such Bank
   shall be owned at that time by the Company; or (ii) permit a Bank to merge or
   consolidate or convey or transfer all or substantially all of its assets,
   unless at least 80% of the capital stock of each class (after giving effect
   to such transaction and to shares issuable upon conversion or exchange of
   outstanding securities convertible or exchangeable into capital stock,
   including such securities, if any, which may be issued in such transaction)
   of the surviving corporation in the case of a merger or consolidation or of
   the transferee corporation in the case of a conveyance or transfer, shall be
   owned at that time by the Company.  (Section 9.12)

        Ownership of Material Subsidiary Stock.  The Company will not take any
   action which would result in a decrease in the percentage of the outstanding
   shares of voting stock of any Material Subsidiary directly or indirectly
   owned by the Company, except as a result of (i) the issuance of directors'
   qualifying shares; (ii) sales or other dispositions to the Company or to one
   or more Material Subsidiaries; (iii) the purchase or retirement of shares
   with the proceeds of newly issued shares; or (iv) the sale of capital stock
   at a price determined by the Company (which determination may be evidenced by
   a resolution of the Company's Board of Directors) to be the fair value
   thereof.  (Section 9.10)

        Limitation on Liens.  Except as provided below, the Company will not
   issue, assume or guarantee any indebtedness for borrowed money
   ("indebtedness") secured by a mortgage, encumbrance, security interest,
   pledge, lien or charge (a "pledge" or "pledges") of or upon any property of
   the Company, whether such property is owned at the date of the Indenture or
   thereafter acquired, without effectively providing that the Notes (together
   with, if the Company shall so determine, any other indebtedness issued,
   assumed by the Company and then existing or thereafter created) shall be
   secured equally and ratably with (or prior to) such indebtedness, so long as
   such indebtedness shall be so secured.

        The foregoing does not apply to:  (i)  pledges upon any shares of
   capital stock or indebtedness acquired by the Company after the date of the
   Indenture (A) to secure the payment of all or any part of the purchase price
   of such shares of capital stock or indebtedness upon the acquisition thereof
   by the Company, or (B) to secure any indebtedness issued, assumed or
   guaranteed by the Company prior to, at the time of, or within 360 days after
   the acquisition of such shares of capital stock or indebtedness, which
   indebtedness is issued, assumed or guaranteed for the purpose of financing or
   refinancing all or any part of the purchase price of such shares of capital
   stock or indebtedness;  (ii)  pledges of or upon shares of capital stock or
   indebtedness, which pledges exist at the time of acquisition of such shares
   or indebtedness by the Company;  (iii)  pledges of or upon any property of a
   corporation, which pledges exist at the time such corporation is merged with
   or into or consolidated with the Company or which pledges exist at the time
   of a sale or transfer of the properties of a corporation as an entirety or
   substantially as an entirety to the Company; (iv)  mortgages existing on the
   date of the Indenture; and  (v)  any extension, renewal, substitution,
   refinancing, refunding or replacement (or successive extensions, renewals,
   substitutions, refinancings, refundings or replacements) (each a
   "refinancing") in whole or in part of any pledge existing at the date of the
   Indenture or any pledge referred to in clauses (i) through (iv) above,

                                      -14-
<PAGE>
 
   inclusive, provided, however, that the principal amount of indebtedness
   secured thereby may not exceed the principal amount of indebtedness so
   secured at the time of the refinancing plus the aggregate amount of premiums,
   other payments, costs and expenses required to be paid or incurred in
   connection with the refinancing, and that the refinancing shall be limited to
   all or a part of the shares of capital stock or indebtedness which was
   subject to the pledge so extended, renewed, substituted, refinanced, refunded
   or replaced.

        The Company may, without equally and ratably securing the Debt
   Securities, issue, assume or guarantee indebtedness secured by a pledge not
   excepted by clauses (i) through (v) above, so long as after giving effect
   thereto, the Company will own at least 80% of the capital stock of all of its
   Material Subsidiaries then issued and outstanding, free and clear of any
   pledge.  (Section 9.9)

        The Indenture does not contain any provisions other than the foregoing
   which will restrict the Company form incurring, assuming or becoming liable
   with respect to any indebtedness or other obligations, whether secured or
   unsecured, or from paying dividends or making other distributions on its
   capital stock or purchasing or redeeming its capital stock.  The Indenture
   does not contain any financial ratios, or specified levels of net worth or
   liquidity to which the Company must adhere.  In addition, the Indenture does
   not contain any provision which would require that the Company repurchase or
   redeem or otherwise modify the terms of any of the Notes upon a change in
   control or other events involving the Company which may adversely affect the
   creditworthiness of the Notes.

   MERGERS, CONSOLIDATIONS AND TRANSFERS OF ASSETS

        The Company may merge or consolidate with or into any other corporation
   or sell, convey, transfer or otherwise dispose of all or substantially all of
   its assets to any Person, if: (a) (i) in the case of a merger or
   consolidation, the Company is the surviving corporation, or (ii) in the case
   of a merger or consolidation where the Company is not the surviving
   corporation and in the case of any such sale, conveyance, transfer or other
   disposition, the successor or acquiring corporation is a corporation
   organized and existing under the laws of the United States or a State thereof
   and such corporation expressly assumes by supplemental indenture all the
   obligations of the Company under the Debt Securities and under the Indenture
   or such assumption is provided by law; (b) immediately thereafter, giving
   effect to such merger or consolidation, or such sale, conveyance, transfer or
   other disposition, no Default or Event of Default shall have occurred and be
   continuing; and (c) the Company has delivered to the Trustee an Officers'
   Certificate and an Opinion of Counsel each stating that such merger or
   consolidation, or such sale, conveyance, transfer or other disposition
   complies with the Indenture and that all conditions precedent therein
   provided for relating to such transaction have been complied with.  In the
   event of the assumption by a successor corporation of the obligations of the
   Company as provided in clause (a)(ii) of the immediately preceding sentence,
   such successor corporation shall succeed to and be substituted for the
   Company under the Indenture and under the Debt Securities and all obligations
   of the Company thereunder shall terminate.  (Section 7.1).

   TRANSACTIONS WITH AFFILIATES

        The Company will not enter into any transaction (including the purchase,
   sale or exchange of property or the rendering of any service) with any
   Affiliate of the Company or any Subsidiary, other than in the ordinary course
   of business and upon fair and reasonable terms taking into account the nature
   of the Company's or the Subsidiary's business. (Section 9.11).

   CORPORATE EXISTENCE

        Subject to the permitted actions described above in "-Mergers,
   Consolidations and Transfers of Assets," the Company will at all times do or
   cause to be done all things necessary to preserve and keep in full force and
   effect its corporate existence and rights and franchises; provided, however,
   that the Company may abandon or terminate any right or franchise if, in the
   determination of the Company, such abandonment or termination is

                                      -15-
<PAGE>
 
   in the best interests of the Company and does not materially adversely affect
   the ability of the Company to operate its business or to fulfill its
   obligations under the Indenture.  (Section 9.4).

   WAIVERS OF CERTAIN COVENANTS

        The Company may fail or omit in any particular instance to comply with
   any of the covenants set forth in the Indenture (other than the covenants
   relating to payment of principal, premium and interest, maintaining an office
   or agency or preserving its corporate existence) with respect to any series
   of Debt Securities if the Company shall have obtained and filed with the
   Trustee prior to the time for such compliance the consent in writing of the
   Holders of at least a majority in aggregate principal amount of all of the
   Debt Securities of such series at the time Outstanding either waiving such
   compliance in such instance or generally waiving compliance with such
   covenant or covenants, but no such waiver shall extend to or affect any
   obligation not expressly waived or impair any right consequent thereon.
   (Section 9.13).

   EVENTS OF DEFAULT, NOTICE AND WAIVER

        The Indenture provides that the following events are "Events of Default"
   with respect to any series of Debt Securities:  (a) a default for 30 days in
   the payment of any installment of interest on any Debt Security of such
   series; (b) a default in the payment of any principal of, or premium, if any,
   on, any such Debt Security of such series at its Maturity, upon redemption
   (if applicable) or otherwise; (c) a default for 60 days after written notice
   to the Company by the Trustee, or to the Company and the Trustee by the
   Holders of at least 33% in principal amount of the Outstanding Debt
   Securities of such series, in the performance of, or breach of, any other
   covenant or warranty of the Company in respect of the Debt Securities of such
   series contained in the Indenture; (d) a default under any agreement or
   instrument under which there may be issued or by which there may be secured
   or evidenced any indebtedness for money borrowed (excluding for such purposes
   non-recourse indebtedness having in the aggregate an outstanding principal
   amount of less than $25 million), whether such indebtedness now exists or
   shall hereafter be created, having an outstanding principal amount of $25
   million or more in the aggregate, which default shall have resulted in such
   indebtedness being declared due and payable prior to the date on which it
   would otherwise have become due and payable, without such declaration of
   acceleration having been rescinded or annulled within a period of ten days
   (or sixty days if the default is not caused by a failure to pay when due
   principal or interest on such indebtedness within the applicable grace
   period) after there shall have been given, by registered or certified mail,
   to the Company by the Trustee, or to the Company and the Trustee by the
   Holders of at least 33% in aggregate principal amount of the Outstanding Debt
   Securities of such series, a written notice specifying such Event of Default,
   and stating that such notice is a "Notice of Default" under the Indenture;
   provided, however, that if such default under such agreement or instrument is
   remedied or cured by the Company or waived by the holders of such
   indebtedness, then such Event of Default by reason thereof shall be deemed
   likewise to have been thereupon remedied, cured or waived without further
   action upon the part of either the Trustee or any of the Holders of the Debt
   Securities of that series; (e) certain events of bankruptcy, insolvency or
   reorganization, or court appointment of a receiver, liquidator or trustee of
   the Company or its subsidiaries; or (f) any other Event of Default provided
   in or pursuant to the Officer's Certificate, the applicable resolution of the
   Board of Directors, or established in the supplemental indenture under which
   such series of Debt Securities is issued.  (Section 5.1).  No Event of
   Default with respect to a particular series of Debt Securities necessarily
   constitutes an Event of Default with respect to any other series of Debt
   Securities issued under the Indenture.

        Within 90 days after the occurrence of any Default with respect to any
   series of Debt Securities which is continuing, the Trustee for such series
   must give the Holders of Debt Securities of such series notice of all
   Defaults of which it has knowledge and that have not been cured or waived.
   Nevertheless, except in the case of a Default in payment on the Debt
   Securities of any series, the Trustee may withhold notice to the Holders of
   Debt Securities of any series of any Default with respect to such series if
   and so long as it determines that the withholding of such notice is in the
   interest of such Holders; provided, however, that, in the case of any default
   or breach of the character specified,in clause (c) of the preceding paragraph
   with respect to the Debt

                                      -16-
<PAGE>
 
   Securities of such series, no such notice to Holders shall be given until at
   least 60 days after the occurrence thereof.  (Section 6.6).

        If an Event of Default with respect to any series of Debt Securities at
   the time Outstanding shall have occurred and is continuing, the Trustee or
   the Holders of at least 33% in aggregate principal amount of the Outstanding
   Debt Securities of such series may, by written notice, declare the principal
   amount thereof (or, if the Debt Securities of such series are Original Issue
   Discount Securities, such portion of the principal amount as may be specified
   in the terms of such series) to be due and payable immediately.  (Section
   5.2).

        The Indenture contains a provision entitling the Trustee to be
   indemnified by the Holders of Debt Securities issued thereunder before
   proceeding to exercise any right or power vested in the Trustee under the
   Indenture at the request of any Holders.  (Section 6.2).  The Indenture
   provides that the Holders of a majority in aggregate principal amount of the
   Outstanding Debt Securities of any series issued thereunder may, with certain
   exceptions, direct 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, with respect to the Debt Securities of such
   series.  (Section 5.8).  The right of a Holder to institute a proceeding with
   respect to the Indenture is subject to certain conditions precedent,
   including notice and indemnity to the Trustee, but each Holder has a right to
   the receipt of payment of principal, premium, if any, and interest, if any,
   at the respective Stated Maturities of the Debt Securities (or, in the case
   of a redemption, on the Redemption Date) or to institute suit for the
   enforcement thereof, which right shall not be impaired or affected without
   the consent of such Holder.  (Sections 5.9 and 5.10).

        The Holders of a majority in aggregate principal amount of the
   Outstanding Debt Securities of any series may, on behalf of the Holders of
   all such Debt Securities, waive any past Default or Event of Default with
   respect to such series and its contingencies, except (a) a Default or Event
   of Default in the payment of principal of, premium, if any, or interest, if
   any, on any Debt Securities of such series, or (b) in respect of any covenant
   or provision of the Indenture that cannot be modified or amended without the
   consent of the Holder of each Outstanding Debt Security of that series
   adversely affected.  (Sections 5.7 and 8.2).

        The Indenture requires the Company to furnish to the Trustee annual
   statements as to the fulfillment by the Company of its obligations under the
   Indenture. (Section 9.7).

   MODIFICATION OF THE INDENTURE

        The Company, when authorized by a Board Resolution, and the Trustee may,
   at any time and from time to time, without the consent of any Holders of Debt
   Securities, modify and amend the Indenture, for any of the following
   purposes:  (a) to evidence the succession of another corporation to the
   Company and the assumption by any such successor of the covenants of the
   Company under the Indenture and in the Debt Securities; (b) to add to the
   covenants of the Company for the benefit of the Holders of all or any series
   of Debt Securities (and if such covenants are to be for the benefit of less
   than all series of Debt Securities, stating that such covenants are expressly
   being included solely for the benefit of such series) or to surrender any
   right or power conferred by the Indenture upon the Company; (c) to add any
   additional Events of Default with respect to all or any series of Debt
   Securities; (d) to add to or change any of the provisions of the Indenture to
   facilitate the issuance of Debt Securities in global form; (e) to add to,
   change or eliminate any of the provisions of the Indenture; provided,
   however, that any such addition, change or elimination shall become effective
   only when there is no Debt Security Outstanding of any series created prior
   to the execution of the supplemental indenture which is entitled to the
   benefit of such provision; (f) to secure the Debt Securities; (g) to
   establish the form or terms of Debt Securities of any series as permitted by
   Sections 2.1 and 3.1 of the Indenture; (h) to evidence and provide for the
   acceptance of appointment under the Indenture by a successor Trustee with
   respect to the Debt Securities of one or more series and to add to or change
   any of the provisions of the Indenture as shall be necessary to provide for
   or facilitate the administration of the trusts under the Indenture by more
   than one Trustee, pursuant to the requirements of Section 6.11 of the
   Indenture; (i) to correct or supplement any provision under the

                                      -17-
<PAGE>
 
   Indenture which may be inconsistent with any other provision under the
   Indenture or to make any other provisions with respect to matters or
   questions arising under the Indenture, provided, however, such action shall
   not adversely affect the interests of the Holders of Debt Securities of any
   series issued under the Indenture in any material respect; or to cure any
   ambiguity or correct any mistake; or (j) to modify, eliminate or add to the
   provisions of the Indenture to the extent necessary to effect the
   qualification of the Indenture under the Trust Indenture Act of 1939 (the
   "TIA") or under any similar federal statute subsequently enacted and to add
   to the Indenture such other provisions as may be expressly required under the
   TIA.  (Section 8.1).

        Modifications and amendments to the Indenture may be made by the Company
   and the Trustee with the written consent of the Holders of a majority of the
   aggregate principal amount of each series of Debt Securities at the time
   Outstanding that is adversely affected thereby; provided, however, that no
   such modification or amendment may, without the consent of the Holder of each
   Outstanding Debt Security of such series adversely affected thereby: (i)
   change the Stated Maturity of the principal of, or any installment of
   principal of or interest on, any Debt Security of such series, or reduce the
   principal amount thereof or the rate of interest thereon or any premium
   payable upon the redemption thereof, or reduce the amount of the principal of
   an Original Issue Discount Security of such series that would be due and
   payable upon a declaration of acceleration of the Maturity thereof pursuant
   to Section 5.2 of the Indenture, or impair the right to institute suit for
   the enforcement of any such payment on or after the Stated Maturity thereof
   (or, in the case of redemption, on or after the Redemption Date); (ii) reduce
   the percentage in aggregate principal amount of the Outstanding Debt
   Securities of such series, the consent of whose Holders is required for any
   such supplemental indenture, or the consent of whose Holders is required for
   any waiver (of compliance with certain provisions of the Indenture or certain
   defaults thereunder and their consequences) provided for in the Indenture;
   (iii) change any obligation of the Company to maintain an office or agency in
   the Place of Payment for the Debt Securities of such series where such Debt
   Securities may be presented or surrendered for payment, where such Debt
   Securities of such series may be surrendered for registration of transfer or
   exchange or where notices and demands to or upon the Company in respect of
   the Debt Securities of such series may be served; or (iv) make any change in
   Section 5.7 or Section 8.2 of the Indenture except to increase any percentage
   or to provide that certain other provisions of the Indenture cannot be
   modified or waived without the consent of the Holders of each Outstanding
   Debt Security of such series adversely affected thereby.  (Section 8.2).

   SATISFACTION AND DISCHARGE; DEFEASANCE

        The Indenture, with respect to any series of Debt Securities (except for
   certain specified surviving obligations referred to below), will be
   discharged and canceled upon the satisfaction of certain conditions,
   including the following: (a) all Debt Securities of such series not
   theretofore delivered to the Trustee for cancellation have become due or
   payable, will become and due and payable at their Stated Maturity within one
   year, or are to be called for redemption within one year; and (b) the deposit
   with the Trustee of an amount sufficient to pay the principal, premium, if
   any, and interest to the Maturity of all Debt Securities of such series.
   Upon any such discharge of the Company's obligations, the Holders of the Debt
   Securities of such series shall no longer be entitled to the benefits of the
   Indenture, except for the purposes of registration of transfer and exchange
   of the Debt Securities or replacement of lost, stolen or mutilated Debt
   Securities and shall look only to such deposited funds or obligations for
   payment.  (Sections 4.1 and 4.2).

        The Indenture also provides that the Company may elect:

             (a) to be discharged from its obligations with respect to the Debt
        Securities of or within a series on and after the date the conditions
        described below regarding Section 4.6 of the Indenture are satisfied
        (hereinafter "defeasance").  For this purpose, such defeasance means
        that the Company shall be deemed to have paid and discharged the entire
        indebtedness represented by such Debt Securities which shall thereafter
        be deemed to be "Outstanding" only for the purposes of Article 4 of the
        Indenture, and to have satisfied all its other obligations under such
        Debt Securities and the Indenture insofar as such Debt Securities are
        concerned (and the Trustee, at the expense of the Company, shall on a
        Company Order

                                      -18-
<PAGE>
 
        execute proper instruments acknowledging the same), except the following
        which shall survive until otherwise terminated or discharged hereunder:
        (i) the rights of Holders of such Debt Securities to receive, solely
        from the trust funds described below regarding Section 4.6(a) of the
        Indenture, payments in respect of the principal of, premium, if any, and
        interest, if any, on such Debt Securities when such payments are due;
        (ii) the rights, powers, trusts, duties and immunities of the Trustee
        under the Indenture; and (iii) Article 4 of the Indenture.  Subject to
        compliance with Article 4 of the Indenture, the Company may exercise
        this option notwithstanding the prior exercise of its option to effect
        covenant defeasance (as defined below) with respect to such Debt
        Securities.  (Section 4.4).

             (b)  to be released from its obligations with respect to the Debt
        Securities of or within a series under "--Mergers, Consolidations and
        Transfers of Assets" and "--Certain Covenants" above and certain other
        obligations, and, if specified pursuant to provisions of the Indenture
        establishing the terms of such Debt Securities, its obligations under
        any other covenants with respect to such Debt Securities on and after
        the date the conditions set forth below in the next paragraph are
        satisfied (hereinafter "covenant defeasance"), and such Debt Securities
        shall thereafter be deemed to be not "Outstanding" for the purpose of
        any request, demand, authorization, direction, notice, consent, waiver
        or other Act of Holders (and the consequences of any thereof) in
        connection with such obligations or such other covenants, but shall
        continue to be deemed "Outstanding" for all other purposes of the
        Indenture.  For this purpose, such covenant defeasance means that, with
        respect to such Debt Securities, the Company may omit to comply with and
        shall have no liability in respect of such obligations or such other
        covenants, whether directly or indirectly, by reason of any reference
        elsewhere in the Indenture to any such obligation or such other
        covenants or by reason of any reference to any such obligation or such
        other covenants to any other provision in the Indenture or in any other
        document or otherwise and such omission to comply shall not constitute a
        Default or an Event of Default under the Indenture or otherwise, as the
        case may be, but, except as specified above, the remainder of the
        Indenture and such Debt Securities shall be unaffected thereby.
        (Section 4.5).

        Such defeasance or covenant defeasance will take effect with respect to
   any Debt Securities of or within a series at any time prior to the Stated
   Maturity or redemption thereof only when:

             (a)  The Company shall have deposited or caused to be deposited
        irrevocably with the Trustee (or another trustee satisfying the
        eligibility requirements of the Indenture who shall agree to comply
        with, and shall be entitled to the benefits of, certain specified
        provisions of the Indenture relating to defeasance or covenant
        defeasance and liability with respect to trust funds, for purposes of
        such provisions also a "Trustee") as trust funds in trust for the
        purpose of making the payments referred to in clauses (x) and (y) below,
        specifically pledged as security for, and dedicated solely to, the
        benefit of the Holders of such Debt Securities, with instructions to the
        Trustee as to the application thereof, (i) money in an amount, or (ii)
        Government Obligations which through the payment of interest and
        principal in respect thereof in accordance with their terms will
        provide, not later than one day before the due date of any payment
        referred to in clause (x) or (y) below, money in an amount or (iii) a
        combination thereof in an amount, sufficient, in the opinion of a
        nationally recognized firm of independent certified public accountants
        expressed in a written certification thereof delivered to the Trustee,
        to pay and discharge, and which shall be applied by the Trustee to pay
        and discharge, (x) the principal of, premium, if any, and interest, if
        any, on such Debt Securities on the Maturity of such principal or
        installment of principal or interest and (y) any mandatory sinking fund
        payments applicable to such Debt Securities on the day on which such
        payments are due and payable in accordance with the terms of the
        Indenture and such Debt Securities.  Before such a deposit the Company
        may make arrangements satisfactory to the Trustee for the redemption of
        Debt Securities at a future date or dates in accordance with the
        Indenture which shall be given effect in applying the foregoing.

             (b)  Such defeasance or covenant defeasance shall not result in a
        breach or violation of, or constitute a Default or Event of Default
        under the Indenture or result in a breach or violation of, or

                                      -19-
<PAGE>
 
        constitute a default under, any other material agreement or instrument
        to which the Company is a party or by which it is bound.

             (c)  No Event of Default of the type described in clause (e) of "--
        Events of Default, Notice and Waiver" above with respect to such Debt
        Securities shall have occurred and be continuing during the period
        commencing on the date of such deposit and ending on the 91st day after
        such date (it being understood that this condition shall not be deemed
        satisfied until the expiration of such period).

             (d)  In the case of an exercise by the Company of its option to
        effect a defeasance as described above, the Company shall have delivered
        to the Trustee an Officers' Certificate and an Opinion of Counsel to the
        effect that (i) the Company has received from, or there has been
        published by, the Internal Revenue Service a ruling, or (ii) since the
        date of execution of the Indenture, there has been a change in the
        applicable Federal income tax law, in either case to the effect that,
        and based thereon such opinion shall confirm that, the Holders of such
        Debt Securities will not recognize income, gain or loss for Federal
        income tax purposes as a result of such defeasance and will be subject
        to Federal income tax on the same amount and in the same manner and at
        the same times, as would have been the case if such deposit, defeasance
        and discharge had not occurred.

             (e)  In the case of an exercise by the Company of its option to
        effect a covenant defeasance as described above, the Company shall have
        delivered to the Trustee an Opinion of Counsel to the effect that the
        Holders of such Debt Securities will not recognize income, gain or loss
        for Federal income tax purposes as a result of such covenant defeasance
        and will be subject to Federal income tax on the same amounts, in the
        same manner and at the same times as would have been the case if such
        covenant defeasance had not occurred.

             (f)  The Company shall have delivered to the Trustee an Officers'
        Certificate and an Opinion of Counsel, each stating that all conditions
        precedent to such defeasance as described above or such covenant
        defeasance as described above (as the case may be) have been complied
        with and an Opinion of Counsel to the effect that either (i) as a result
        of a deposit pursuant to subparagraph (a) above and the related exercise
        of the Company's option to effect such defeasance as described above or
        to affect such covenant defeasance as described above (as the case may
        be), registration is not required under the Investment Company Act of
        1940, as amended, by the Company, with respect to the trust funds
        representing such deposit or by the Trustee for such trust funds or (ii)
        all necessary registrations under said Act have been effected.

             (g)  Such defeasance or covenant defeasance shall be effected in
        compliance with any additional or substitute terms, conditions or
        limitations which may be imposed on the Company in connection therewith
        as contemplated by the provisions of the Indenture establishing the
        terms of such Debt Securities.  (Section 4.6).

   PAYMENT AND TRANSFER

        Principal of, premium, if any, and interest, if any, on the Debt
   Securities of any series are to be payable at the Place of Payment for such
   series, which may be the Corporate Trust Office of the Trustee or any other
   office or agency maintained by the Company for such purposes, provided that
   payment of interest, if any, on Debt Securities may be made at the option of
   the Company by check mailed to the persons in whose names such Debt
   Securities are registered at the close of business on the day or days
   specified in the applicable Prospectus Supplement.  (Sections 3.7 and 9.2).

        Debt Securities may be transferred or exchanged at the Place of Payment
   for such series, which may be the Corporate Trust Office of the Trustee or at
   any other office or agency maintained by the Company for such purposes,
   subject to the limitations in the Indenture, without the payment of any
   service charge except for

                                      -20-
<PAGE>
 
   any tax or governmental charge incidental thereto.  (Section 3.5).

   SAME-DAY SETTLEMENT

        Settlement for the Notes will be made by the underwriters, dealers or
   agents in immediately available funds and all applicable payments of
   principal, premium and interest on the Notes will be made by the Company in
   immediately available funds.

   NO PERSONAL LIABILITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS OR DIRECTORS

        The Indenture provides that no recourse under or upon any obligation,
   covenant or agreement of or contained in the Indenture or of or contained in
   any Note, or for any claim based thereon or otherwise in respect thereof, or
   because of the creation of any indebtedness represented thereby, shall be had
   against any incorporator, stockholder, officer or director, as such, past or
   present of the Company or of any successor Person.  Each Holder, by accepting
   the Notes, waives and releases all such liability.  (Section 1.13).

   CONCERNING THE TRUSTEE

        The Indenture provides that, except during the continuance of an Event
   of Default, the Trustee will perform only such duties as are specifically set
   forth in the Indenture.  If an Event of Default has occurred and is
   continuing, the Trustee will use the same degree of care and skill in its
   exercise of the rights and powers vested in it by the Indenture as a prudent
   person would exercise under the circumstances in the conduct of such person's
   own affairs.  (Section 6.1).

        The Indenture and provisions of the TIA incorporated by reference
   therein contain limitations on the rights of the Trustee, should it become a
   creditor of the Company, to obtain payment of claims in certain cases or to
   realize on certain property received by it in respect of any such claims, as
   security or otherwise.  The Trustee is permitted to engage in other
   transactions; provided, however, that if it acquires any conflicting
   interest, it must eliminate such conflict or resign.  (Section 6.3).

        Harris Trust and Savings Bank is the Trustee under the Indenture.  The
   Company maintains banking relationships in the ordinary course of business
   with the Trustee.

   BOOK-ENTRY SYSTEM

        The Notes will be represented by one fully registered Global Security
   deposited with, or on behalf of, the Depository Trust Company ("DTC") or
   other successor depositary (DTC or such other depositary appointed by the
   Company is herein referred to as the "Depositary") and registered in the name
   of the Depositary or its nominee.  The Notes will not be issuable in
   definitive form, except under the limited circumstances described herein.

        DTC has advised the Company and the Underwriters that it intends to
   follow the procedures described below:

             The Depositary will act as securities depositary for the Global
        Security.  The Global Security will be issued as a fully registered
        security registered in the name of Cede & Co. (the Depositary's
        partnership nominee).

             The Depositary is a limited-purpose trust company organized under
        the New York Banking Law, a "banking organization" within the meaning of
        the New York Banking Law, a member of the Federal Reserve System, a
        "clearing corporation" within the meaning of the New York Uniform
        Commercial Code, and a "clearing agency" registered pursuant to the
        provisions of Section 17A of the

                                      -21-
<PAGE>
 
        Exchange Act.  The Depositary holds securities that its participants
        ("Participants") deposit with the Depositary.  The Depositary also
        facilitates the settlement among Participants of securities
        transactions, such as transfers and pledges, in deposited securities
        through electronic computerized book-entry changes in Participants'
        accounts, thereby eliminating the need for physical movement of
        securities certificates.  Direct Participants include securities brokers
        and dealers, banks, trust companies, clearing corporations and certain
        other organizations ("Direct Participants").  The Depositary is owned by
        a number of its Direct Participants and by the New York Stock Exchange,
        Inc., the American Stock Exchange, Inc., and the National Association of
        Securities Dealers, Inc.  Access to the Depositary's system is also
        available to others such as securities brokers and dealers, banks and
        trust companies that clear through or maintain a custodial relationship
        with a Direct Participant, either directly or indirectly ("Indirect
        Participants").  The Rules applicable to the Depositary and its
        Participants are on file with the Commission.

             Purchases of the Notes must be made by or through Direct
        Participants, which will receive a credit for the Notes on the
        Depositary's records.  The ownership interest of each actual purchaser
        of each Note ("Beneficial Owner") is in turn recorded on the Direct and
        Indirect Participant's records.  Transfers of ownership interests in the
        Notes are to be accomplished by entries made on the books of
        Participants acting on behalf of Beneficial Owners.  Beneficial Owners
        will not receive certificates representing their ownership interests in
        the Notes, except in the event that use of the book-entry system for the
        Notes is discontinued.

             To facilitate subsequent transfers, all Notes deposited by
        Participants with the Depositary are registered in the name of the
        Depositary's partnership nominee, Cede & Co.  The deposit of Notes with
        the Depositary and their registration in the name of Cede & Co. effect
        no change in beneficial ownership.  The Depositary has no knowledge of
        the actual Beneficial Owners of the Notes; the Depositary's records
        reflect only the identity of the Direct Participants to whose accounts
        such Notes are credited, which may or may not be the Beneficial Owners.
        The Participants will remain responsible for keeping account of their
        holdings on behalf of their customers.

             Conveyance of Notes and other communications by the Depositary to
        Direct Participants, by Direct Participants to Indirect Participants,
        and by Direct Participants and Indirect Participants to Beneficial
        Owners are governed by arrangements among them, subject to any statutory
        or regulatory requirements as may be in effect from time to time.

             Neither the Depositary nor Cede & Co. will consent or vote with
        respect to the Notes.  Under its usual procedures, the Depositary mails
        an Omnibus Proxy to the issuer as soon as possible after the record
        date.  The Omnibus Proxy assigns Cede & Co.'s consenting or voting
        rights to those Direct Participants to whose accounts the Notes are
        credited on the record date (identified in a listing attached to the
        Omnibus Proxy).

             Principal and interest payments on the Notes will be made to the
        Depositary.  The Depositary's practice is to credit Direct Participants'
        accounts on the payable date in accordance with their respective
        holdings shown on the Depositary's records unless the Depositary 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 the Depositary, the Paying Agent or the Company,
        subject to any statutory or regulatory requirements as may be in effect
        from time to time.  Payment of principal and interest to the Depositary
        is the responsibility of the Company or the Paying Agent, disbursement
        of such payments to Direct Participants shall be the responsibility of
        the Depositary, and disbursement of such payments to the Beneficial
        Owners shall be the responsibility of Direct and Indirect Participants.

                                      -22-
<PAGE>
 
         
        So long as the Depositary for the Global Security, or its nominee, is
   the registered owner of the Global Security, the Depositary or its nominee,
   as the case may be, will be considered the sole owner or Holder of the Notes
   represented by the Global Security for all purposes under the Indenture.
   Except as set forth below, owners of beneficial interests in the Global
   Security will not be entitled to have Notes represented by the Global
   Security registered in their names, will not receive or be entitled to
   receive physical delivery of Notes in definitive form and will not be
   considered the owners or Holders thereof under the Indenture.  Accordingly,
   each person owning a beneficial interest in the Global Security must rely on
   the procedures of the Depositary and, if such person is not a Participant,
   those of the Participants through which such person owns its interest, in
   order to exercise any rights of a Holder under the Indenture.

        The laws of some jurisdictions require that certain purchasers of
   securities take physical delivery of such securities in definitive form.
   Such limits and laws may impair the ability to transfer beneficial interests
   in the Global Security.

        Principal and interest payments on Notes registered in the name of or
   held by the Depositary or its nominee will be made to the Depositary or its
   nominee, as the case may be, as the registered owner or the Holder of the
   Global Security representing such Notes.  Neither the Company, the Paying
   Agent nor the Trustee 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 or for maintaining, supervising or
   reviewing any records relating to such beneficial ownership interests.

        If at any time the Depositary notifies the Company that it is unwilling
   or unable to continue as Depositary or if at any time the Depositary shall no
   longer be eligible under the Indenture, the Company shall appoint a successor
   Depositary with respect to the Notes.  If a successor Depositary is not
   appointed by the Company within 90 days after it receives such notice or
   becomes aware of such ineligibility, the Company will issue certificated
   Notes of like tenor, in authorized denominations and in an aggregate
   principal amount equal to the principal amount of the Global Security in
   exchange for the Global Security.  (Section 3.5)

        The Company may at any time in its sole discretion determine that the
   Notes issued in global form shall no longer be represented by the Global
   Security, In such event the Company will issue certificated Notes of like
   tenor, in authorized denominations and in an aggregate principal amount equal
   to the principal amount of the Global Security in exchange for the Global
   Security.  (Section 3.5)

ITEM 17.  UNDERTAKINGS

(1)  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 that is incorporated by reference in
     this registration statement shall be deemed to be a new registration
     statement relating to the Securities offered herein, and the offering of
     such Securities at that time shall be deemed to be the initial bona fide
     offering thereof.

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

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

(4)  For 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.

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

          The undersigned Registrant hereby undertakes to file an application
for the purpose of determining the eligibility of the trustee to act under
Subsection (c) of Section 310 of the Trust Indenture Act (the "Act") in
accordance with the rules and regulations prescribed by the Commission under
Section 305(b)(2) of the Act.

Ladies and Gentlemen:

     St. Paul Bancorp, Inc., a Delaware corporation (the "Company"), proposes to
issue and sell to you (the "Underwriters") its ____% Senior Notes due 2004 in an
aggregate principal amount of $100,000,000 (the "Notes").  The Notes shall be
issued under an indenture, dated as of _________, 1997 (the "Indenture"),
between the Company and Harris Trust and Savings Bank, as Trustee (the
"Trustee"), and shall be substantially in the form filed as an exhibit to the
Registration Statement referred to in Section 1 hereof.

     Prior to the purchase and public offering of the Notes by the Underwriters,
the Company and the Underwriters shall enter into an agreement substantially in
the form of Exhibit A hereto (the "Pricing Agreement").  The Pricing Agreement
may take the form of an exchange of any standard form of written
telecommunication between the Company and the Underwriters and shall specify
such applicable information as is indicated in Exhibit A.  The offering of the
Notes will be governed by this Agreement, as supplemented by the Pricing
Agreement.  From and after the date of the execution and delivery of the Pricing
Agreement, this Agreement shall be deemed to incorporate the Pricing Agreement.

     The Company confirms the following agreement with the Underwriters,
relating to the purchase and sale of the Notes.

     1.   REGISTRATION STATEMENT AND PROSPECTUS.  The Company has prepared and
          -------------------------------------                               
filed with the Securities and Exchange Commission (the "Commission") a
registration statement, and has filed one or more amendments thereto, on Form S-
3 (File No. 333-18677), including in such registration statement and each such
amendment a related prospectus 
<PAGE>
 
subject to completion, in accordance with the provisions of the Securities Act
of 1933, as amended, and the rules and regulations of the Commission thereunder
(collectively, the "Act") and the Trust Indenture Act of 1939, as amended, and
the rules and regulations of the Commission thereunder (collectively, the "Trust
Indenture Act"), relating to the Notes. Copies of that registration statement as
amended to date have been delivered by the Company to the Underwriters. The
Company satisfies the conditions for the use of Form S-3 in connection with the
offer and sale of the Notes. The Company expects to file the prospectus
containing the information required by Rule 430A under the Act pursuant to Rule
424(b) under the Act. The registration statement as amended at the time when it
becomes effective, including all financial schedules and exhibits thereto, is
referred to in this Agreement as the "Registration Statement", and the
prospectus in the form filed with the Commission as part of the Registration
Statement at the time the Registration Statement becomes effective or, if
applicable, in the form first filed pursuant to Rule 424(b) after the
Registration Statement becomes effective, is referred to in this Agreement as
the "Prospectus." Any registration statement filed by the Company pursuant to
Rule 462(b) under the Act (a "Rule 462(b) Registration Statement") shall be
deemed to be part of the Registration Statement. Any prospectus included in the
Rule 462(b) Registration Statement shall be deemed to be part of the Prospectus.
Any reference herein to the Prospectus shall be deemed to refer to and include
the documents incorporated by reference therein pursuant to Item 12 of Form S-3
under the Act, as of the date of such Prospectus, and any reference to any
amendment of or supplement to the Prospectus or the Registration Statement shall
be deemed to refer to and include any documents filed after the date of such
Prospectus or Registration Statement, as the case may be, under the Securities
Exchange Act of 1934, as amended (together with the rules and regulations of the
Commission promulgated thereunder, the "Exchange Act"), and incorporated by
reference in such Prospectus or Registration Statement, as the case may be. If a
Rule 462(b) Registration Statement is required, such Rule 462(b) Registration
Statement shall have been transmitted to the Commission for filing and have
become effective within the prescribed time period, and, prior to the Closing
Date, the Company shall have provided to the Underwriters evidence of such
filing and effectiveness in accordance with Rule 462(b) under the Act.

     2.   AGREEMENT TO SELL AND PURCHASE.  The Company hereby agrees to issue
          ------------------------------
and sell to the Underwriters $100,000,000 principal amount of Notes and, on the
basis of the representations, warranties and agreements of the Company herein
contained and subject to the terms and conditions set forth herein, each
Underwriter agrees, severally and not jointly, to purchase from the Company the
principal amount of Notes set forth opposite the name of such Underwriter in
Schedule I hereto (or such principal amount of Notes as such Underwriter shall
be obligated to purchase pursuant to the provisions of Section 9 hereof).


     3.   TERMS OF PUBLIC OFFERING.  The Company is advised by the Underwriters
          ------------------------                                             
that they have agreed to make a public offering of their respective portions of
the Notes as soon after the Registration Statement has become effective and the
Pricing Agreement has been 

                                      -2-
<PAGE>
 
executed as in the Underwriters' judgment is advisable and to first offer the
Notes upon the terms set forth in the Prospectus.

     4.   DELIVERY OF THE NOTES AND PAYMENT THEREFOR.
          ------------------------------------------ 

          (a)  Delivery to the Underwriters of the Notes shall be made at 9:00
a.m., Chicago time, on the fourth business day (or the third business day if
required under Rule 15c6-1 under the Act, or unless postponed in accordance with
the provisions of Section 9(b) hereof) following the date of the Pricing
Agreement (the "Closing Date") against payment therefor at the offices of
McDermott, Will & Emery, 227 West Monroe, Chicago, Illinois 60606, or through
the facilities of The Depository Trust Company. The place of closing and the
Closing Date may be varied by agreement between the Underwriters and the
Company.

          (b)  If the Underwriters and the Company have elected to enter into
the Pricing Agreement after the Registration Statement is effective, the
purchase price to be paid by the several Underwriters for the Notes shall be an
amount equal to the initial public offering price, less an amount to be
determined by agreement between the Underwriters and the Company. The initial
public offering price for the Notes shall be a fixed price to be determined by
agreement between the Underwriters and the Company. The interest rate, the
initial public offering price and the price to be paid by the Underwriters for
the Notes when so determined shall be set forth in the Pricing Agreement. If
such prices shall not have been agreed upon and the Pricing Agreement shall not
have been executed and delivered by all parties thereto by the close of business
on the fourth business day following the date of this Agreement, this Agreement
shall terminate forthwith, without liability of any party to any other party,
unless otherwise agreed to by the Company and the Underwriters and except as
otherwise provided in Section 5(l) and Section 7 hereof. If the Underwriters and
the Company have elected to enter into the Pricing Agreement prior to the
registration statement becoming effective, the initial public offering and the
price to be paid by the several Underwriters for the Notes shall have each been
determined and set forth in the Pricing Agreement, dated the date hereof, and an
amendment to the registration statement and the prospectus will be filed by the
Company before the registration statement becomes effective.

          (c)  The Notes shall be registered in such names and in such
authorized denominations as the Underwriters shall request prior to 11:00 a.m.,
Chicago time, on the second full business day preceding the Closing Date. The
Notes shall be made available to the Underwriters in definitive form for
inspection and packaging not later than 11:00 a.m., Chicago time, on the
business day next preceding the Closing Date. The Notes shall be delivered to
the Underwriters on the Closing Date, with any transfer taxes thereon duly paid
by the Company, for the respective accounts of the several Underwriters, against
payment of the purchase price therefor by wire transfer of immediately available
funds to the Company, subject to change by written agreement of the Company and
the Underwriters.

     5.   AGREEMENTS OF THE COMPANY.  The Company agrees with the several
          -------------------------                                      
Underwriters as follows:

          (a)  The Company will endeavor to cause the Registration Statement to
become effective and will advise the Underwriters promptly, and if requested by
the Underwriters will confirm such advice in writing, (i) when the Registration
Statement has become effective and when any post-effective amendment to it
becomes effective, and of the filing of any final prospectus or supplement or
amendment to the Prospectus, (ii) of any request by the Commission for
amendments or supplements to the Registration Statement or Prospectus, (iii) of
the issuance by the Commission of any stop order suspending the effectiveness of
the Registration Statement or of the suspension of qualification of the Notes
for offering or sale in any jurisdiction, or the initiation or contemplation
known to the Company of any proceeding for such purposes, and (iv) within the
period of time referred to in paragraph (f) below, of the happening of any event
which makes any statement made in the Registration Statement or Prospectus
untrue in any material respect or which requires the making of any additions to
or changes in the Registration Statement or Prospectus in order to make the
statements therein not misleading or of the necessity to amend or supplement the
Prospectus to comply with the Act or any other law. If at any time the
Commission shall issue any stop order suspending the effectiveness of the
Registration Statement, the Company will make every reasonable effort to obtain
the withdrawal of such order at the earliest possible moment. If a Rule 462(b)
Registration Statement is required in connection with the offering and sale of
the Notes, the Company has complied or will comply with the requirements of Rule
111 under the Act relating to the payment of filing fees therefor.

          (b)  If, at the time that the Registration Statement becomes
effective, any information shall have been omitted therefrom in reliance upon
Rule 430A under the Act, then following the execution of the Pricing Agreement,
the Company will prepare and file with the Commission in accordance with Rule
430A and Rule 424(b) under the Act copies of an amended Prospectus, or, if
required by Rule 430A, a post-effective amendment to the Registration Statement
(including an amended Prospectus), containing all information so omitted.

          (c)  The Company will furnish to each of the Underwriters, without
charge, one signed copy of the Registration Statement and of each amendment
thereto, including all exhibits thereto, and will also furnish to each of the
Underwriters, without charge, such number of conformed copies of the
Registration Statement, each amendment thereto and documents incorporated
therein by references each Underwriter may reasonably request.

          (d)  The Company will not file any amendment to the Registration
Statement or make any amendment or supplement to the Prospectus of which the
Underwriters shall not previously have been advised or to which any of the
Underwriters promptly after being so advised shall reasonably have objected in
writing.

                                      -4-
<PAGE>
 
          (e)  Prior to the effective date of the Registration Statement, the
Company will deliver to each Underwriter, without charge, copies of each form of
prospectus subject to completion in such quantities as such Underwriter has
reasonably requested or may hereafter reasonably request. The Company consents
to the use, prior to the effective date of the Registration Statement, of each
prospectus subject to completion so furnished by the Company in accordance with
the provisions of the Act and with the securities or Blue Sky laws of the
jurisdictions in which the Notes are lawfully offered by the several
Underwriters and by all dealers.

          (f)  On the effective date of the Registration Statement and
thereafter from time to time during such period as in the opinion of counsel for
the Underwriters a prospectus is required by law to be delivered in connection
with offers or sales of the Notes by an Underwriter or a dealer, the Company
will deliver to each Underwriter and dealer, without charge, as many copies of
the Prospectus including all documents from which information is incorporated by
reference (and any amendment or supplement thereto) as they may reasonably
request. During such period, if any event occurs which in the judgment of the
Company, or in the opinions of counsel for the Company and the Underwriters
after discussions among such counsel, should be set forth in the Prospectus in
order to ensure that the Prospectus does not contain an untrue statement of a
material fact or omits to state a material fact necessary to make the statements
therein, in the light of the circumstances at the time the Prospectus is
delivered to a purchaser, not misleading, the Company will forthwith prepare,
submit to the Underwriters, file with the Commission and deliver, without charge
to the Underwriters and dealers (whose names and addresses will be furnished by
the Underwriters to the Company) to whom Notes have been sold by the
Underwriters or to other dealers upon request, an amendment or supplement, as
appropriate (including, if applicable, an appropriate report under the Exchange
Act which is incorporated by reference in the Prospectus), to the Prospectus so
that the statements in the Prospectus, as so amended or supplemented, will
comply with the standards set forth in this sentence. The Company consents to
the use of such Prospectus (and of any amendments or supplements thereto) in
accordance with the provisions of the Act and with the securities or Blue Sky
laws of the jurisdictions in which the Notes are lawfully offered by the
Underwriters and by all dealers to whom Notes may be sold, both in connection
with the offering or sale of the Notes and for such period of time thereafter as
the Prospectus is required by law to be delivered in connection therewith. In
case any Underwriter is required to deliver a Prospectus more than nine months
after the first date upon which the Notes are offered to the public, the Company
will, upon request but at the expense of such Underwriter, furnish such
Underwriter with reasonable quantities of a Prospectus complying with Section
10(a)(3) of the Act.

          (g)  The Company will cooperate with the Underwriters and counsel for
the Underwriters in connection with the registration or qualification of the
Notes for offer and sale by the several Underwriters and by dealers under the
securities or Blue Sky laws of such jurisdictions as the Underwriters may
designate and will file such consents to service of process or other documents
as may be necessary in order to effect such registration or 

                                      -5-
<PAGE>
 
qualification; provided that in no event shall the Company be obligated to
qualify to do business in any jurisdiction where it is not now so qualified or
to take any action which would subject it to the service of process in suits,
other than those arising out of the offer and sale of the Notes, in any
jurisdiction where it is not now so subject, or to take any action to amend its
Certificate of Incorporation in order to make the Company's securities eligible
for registration or qualification in any jurisdiction.

          (h)  The Company will make generally available to its security holders
an earnings statement of the Company and its subsidiaries, which need not be
audited, as soon as practicable but not later than 18 months after the effective
date of the Registration Statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Act and the rules and regulations of the
Commission thereunder (including Rule 158).

          (i)  So long as any Notes are outstanding the Company will furnish:

               (i)   to its Noteholders generally and to the Underwriters (A)
          at such time after the end of each fiscal year as provided in this
          Indenture, copies of such financial statements of the Company as of
          the end of and for such fiscal year, audited by independent public
          accountants, as are specified in the Indenture and (B) at such time
          after the end of each quarterly fiscal period, except for the last
          quarterly fiscal period in each fiscal year, such financial statements
          (which need not be audited) of the Company for such period as are
          specified in the Indenture, which shall also be made publicly
          available; and

               (ii)  to the Underwriters (A) as soon as available, a copy of
          each report of the Company of general interest mailed to any class of
          its security holders, (B) copies of all annual reports, quarterly
          reports and current reports on Forms 10-K, 10-Q and 8-K or such other

obligation, agreement, covenant or condition contained in any contract,
indenture, mortgage, loan agreement, note, lease, license or other agreement or

on reasonable terms, trademarks, service marks and trade names necessary to
conduct the businesses, in all material respects, now operated by them, and
neither the Company nor any Subsidiary has received any notice of infringement
of or conflict with asserted rights of others with respect to any trademarks,
service marks or trade names which, singly or in the aggregate, if the subject

affect the financial condition, earnings or business of the Company and the
Subsidiaries taken as a whole.

     7.   INDEMNIFICATION AND CONTRIBUTION.
          -------------------------------- 

          (a)  The Company agrees to indemnify and hold harmless each
Underwriter and each person, if any, who controls such Underwriter within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act from and
against any and all losses, claims, damages, liabilities and reasonable expenses
whatsoever (including any investigation and legal or other expenses incurred in
connection with, and any amount paid in settlement of, any action, suit or
proceeding or any claim asserted) to which they, or any of them, may 

                                      -14-
<PAGE>
 
become subject, arising out of or based upon any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement, any
prospectus subject to completion or the Prospectus or in any amendment or
supplement thereto or arising out of or based upon any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or expenses arise out of or are based upon
any such untrue statement or omission or allegation thereof which has been made
therein or omitted therefrom in reliance upon and in conformity with information
relating to such Underwriter furnished in writing to the Company by or on behalf
of such Underwriter expressly for use therein; provided, however, that the
indemnification contained in this paragraph with respect to any prospectus
subject to completion shall not inure to the benefit of an Underwriter (or of
any person controlling such Underwriter) with respect to any action or claim
arising from the sale of the Notes by such Underwriter brought by any person who
purchased Notes from such Underwriter if (i) a copy of the Prospectus (as
amended or supplemented if any amendments or supplements thereto shall have been
furnished to the Underwriter prior to the written confirmation of the sale
involved) shall not have been given or sent to such person by or on behalf of
the Underwriter with or prior to the written confirmation of the sale involved
and (ii) the untrue statement or omission of a material fact contained in such
prospectus subject to completion was corrected in the Prospectus (as amended or
supplemented, if amended or supplemented, as aforesaid).

          (b)  If any action or claim shall be brought against any Underwriter
or any person controlling such Underwriter in respect of which indemnity may be
sought against the Company, such Underwriter shall promptly notify the Company
(the "indemnifying party") in writing, and the indemnifying party shall assume
the defense thereof, including the employment of counsel and the payment of all
fees and expenses. The Underwriter or any such person controlling such
Underwriter shall have the right to employ separate counsel in any such action
and participate in the defense thereof, but the fees and expenses of such
counsel shall be at the expense of such Underwriter or such controlling person
unless (i) the Company has agreed in writing to pay such fees and expenses, (ii)
the indemnifying party has failed to assume the defense and employ counsel, or
(iii) the named parties to any such action (including any impleaded party)
include such Underwriter or controlling person and the Company and such
Underwriter or controlling person shall have been advised by such counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to the Company (in which case if such
Underwriter or controlling person notifies the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of such Underwriter or controlling person, it being understood,
however, that the indemnifying party shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys for all such Underwriters and controlling persons, which firm shall be
designated in writing by the Underwriters). The indemnifying party shall not be
liable for any settlement of any such action effected without the written
consent of the Company, but 

                                      -15-
<PAGE>
 
if settled with the written consent of the Company, or if there shall be a final
judgment for the plaintiff in any such action and the time for filing all
appeals shall have expired, the indemnifying party agrees to indemnify and hold
harmless the Underwriters and any such controlling persons from and against any
loss or liability by reason of such settlement or judgment.

          (c)  Each Underwriter agrees, severally and not jointly, to indemnify
and hold harmless the Company, its directors, its officers who sign the
Registration Statement and any person controlling the Company to the same extent
as the foregoing indemnity from the Company to each Underwriter, but only with
respect to (i) information relating to such Underwriter furnished in writing to
the Company by or on behalf of such Underwriter expressly for use in any
prospectus subject to completion or the Registration Statement or the Prospectus
or in any amendment or supplement thereto; or (ii) any gross negligence or
willful misconduct of such Underwriter in connection with such Underwriter's
actions taken pursuant to this Agreement. If any action or claim shall be
brought or asserted against the Company, any of its directors, any such officers
or any such controlling persons based on the Registration Statement, the
Prospectus or any prospectus subject to completion or any amendment or
supplement thereto and in respect of which indemnity may be sought against an
Underwriter, such Underwriter shall have the rights and duties given to the
indemnifying party by Section 7(b) hereof (except that if the Company shall have
assumed the defense thereof, such Underwriter shall not be required to do so,
but may employ separate counsel therein and participate in the defense thereof,
but the fees and expenses of such counsel shall be at the expense of such
Underwriter), and the Company, its directors, any such officers and any such
controlling persons shall have the rights and duties given to the Underwriters
by Section 7(b) hereof.

               (d)  (i) If the indemnification of the Underwriters or the
          Company provided for in this Section 7 is unavailable as a matter of
          law to the Underwriters or the Company, as the case may be, in respect
          of any losses, claims, damages, liabilities or expenses referred to
          therein, then the indemnifying party, in lieu of indemnifying such
          indemnified party thereunder, shall contribute to the amount paid or
          payable in damages, liabilities or expenses (i) in such proportion as
          is appropriate to reflect the relative benefits received by the
          Company on the one hand and the Underwriters on the other from the
          offering of the Notes or (ii) if the allocation provided by clause (i)
          above is not permitted by applicable law, in such proportion as is
          appropriate to reflect not only the relative benefits referred to in
          clause (i) above but also the relative fault of the Company on the one
          hand and of the Underwriters on the other in connection with the
          statements or omissions which resulted in such losses, claims,
          damages, liabilities or expenses, as well as any other relevant
          equitable considerations. The relative benefits received by the
          Company on the one hand and the Underwriters on the other shall be
          deemed to be in the same proportion as the total net proceeds from the
          offering (before deducting expenses) received by the Company bear to
          the 

                                      -16-
<PAGE>
 
          total underwriting discount received by the Underwriters, in each case
          as set forth in the table on the cover page of the Prospectus (or any
          amendment or supplement thereto). The relative fault of the Company on
          the one hand and of the Underwriters on the other shall be determined
          by reference to, among other things, whether the untrue or alleged
          untrue statement or the omission or alleged omission relates to
          information supplied by the Company on the one hand or by the
          Underwriters on the other and the parties' relative intent, knowledge,
          access to information and opportunity to correct or prevent such
          statement or omission.

               (ii) The Company and the Underwriters agree that it would not be
          just and equitable if contribution pursuant to this Section 7 were
          determined by pro rata allocation (even if the Underwriters were
          treated as one entity for such purpose) or by any other method of
          allocation which does not take account of the equitable considerations
          referred to in the immediately preceding paragraph. The amount paid or
          payable by an indemnified party as a result of the losses, claims,
          damages, liabilities and expenses referred to in the immediately
          preceding paragraph shall be deemed to include, subject to the
          limitations set forth in this Section 7, any legal or other expenses
          reasonably incurred by such indemnified party in connection with
          investigating or defending any such action or claim. Notwithstanding
          the provisions of this Section 7, no Underwriter shall be required to
          contribute any amount in excess of the amount by which the total price
          at which the Notes underwritten by it and distributed to the public
          exceeds the amount of any damages which such Underwriter has otherwise
          been required to pay by reason of such untrue or alleged untrue
          statement or omission or alleged omission. No person guilty of
          fraudulent misrepresentation (within the meaning of Section 11(f) of
          the Act) shall be entitled to contribution from any person who was not
          guilty of such fraudulent misrepresentation. The Underwriters'
          obligations to contribute pursuant to this Section 7 are several in
          proportion to the number of Notes set forth opposite their respective
          names in Schedule I to this Agreement and not joint.

          (e)  The indemnity and contribution agreements contained in this
Section 7 and the representations and warranties of the Company set forth in
this Agreement shall remain operative and in full force and effect, regardless
of (i) any investigation made by or on behalf of any Underwriter or any persons
controlling such Underwriter, the Company or its directors or officers (or any
persons controlling the Company), (ii) acceptance of any Notes and payment
therefor hereunder and (iii) any termination of this Agreement. A successor or
assign of an Underwriter, the Company or its directors or officers and their
legal and personal representatives (or of any persons controlling an Underwriter
or the Company) shall be entitled to the benefits of the indemnity, contribution
and reimbursement agreements contained in this Section 7.

      8.   CONDITIONS OF THE UNDERWRITERS' OBLIGATIONS. The several obligations
           -------------------------------------------
of the Underwriters to purchase and pay for the Notes hereunder are subject to
the performance by the Company of its obligations hereunder, and to the
following conditions:

           (a)  That the Registration Statement shall have become effective not
later than 4:30 p.m., Chicago time, on the date hereof, or at such later date
and time as shall be consented to in writing by the Underwriters and, if the
Underwriters and the Company have elected to rely upon Rule 430A under the Act,
the price of the Notes and any price-related or other information previously
omitted from the Registration Statement pursuant to such Rule 430A shall have
been transmitted to the Commission for filing pursuant to Rule 424(b) under the
Act within the prescribed time period, and, on or prior to the Closing Date, the
Company shall have provided evidence satisfactory to the Underwriters of such
timely filing, or a post-effective amendment providing such information shall
have been promptly filed and declared effective in accordance with the
requirements of Rule 430A.

           (b)  That subsequent to the effective date of the Registration
Statement, (i) there shall not have occurred any material change, or any
material development involving a prospective change, in or affecting
particularly the business or properties of the Company not contemplated by the
Prospectus, which, in the Underwriters' reasonable opinion, after discussion
with the Company, would materially adversely affect the market for the Notes or
make it unpracticable or inadvisable to proceed with the offering or the
delivery of the Notes, as contemplated herein and in the Prospectus, or to
attempt to enforce contracts for the purchase of Notes, and (ii) the business
and operations of the Company and its Subsidiaries, taken as a whole, shall not
have been materially interfered with by strike, fire, flood, accident or other
calamity (whether or not insured).

           (c)  That the Underwriters shall have received from Hogan & Hartson
L.L.P., special counsel for the Company, a favorable opinion dated the Closing
Date and satisfactory to the Underwriters and the Underwriters counsel to the
effect that:

                (i)   This Agreement and the Pricing Agreement have been duly
           authorized, executed and delivered by the Company and are the legal,
           valid and binding obligations of the Company, enforceable against the
           Company in accordance with their terms, except as may be limited by
           bankruptcy, reorganization, insolvency, moratorium or other laws
           affecting creditors' rights, and except as may be limited by the
           exercise of judicial discretion in applying general principles of
           equity (regardless of whether this Agreement and the Pricing
           Agreement are considered in a proceeding in equity or at law); it
           being understood, however, that the foregoing shall mean only that if
           there is a default in performance of an obligation (i) if a failure
           to pay or other damage can be shown and (ii) if the defaulting party
           can be brought into a court which will hear the case and apply the
           governing law, then, subject to the availability of defenses and the
           aforesaid exceptions, the court will provide a money damage (or
           perhaps injunctive or specific performance) 

                                      -18-

           remedy. Notwithstanding the above, such counsel need express no
           opinion as to the enforceability of the indemnity and contribution
           provisions contained in Section 7 of this Agreement.

                (ii)  The Notes have been duly and validly authorized by the
           Company and, when duly authenticated by the Trustee and issued,
           delivered and sold in accordance with this Agreement and the
           Indenture, will have been duly and validly executed, authenticated,
           issued and delivered and will constitute valid and binding
           obligations of the Company, entitled to the benefits provided by the
           Indenture (subject to the exceptions hereinafter set forth)
           enforceable against the Company in accordance with their terms and
           the terms of the Indenture, except as the enforceability thereof may
           be limited by bankruptcy, reorganization, insolvency, moratorium or
           other laws affecting creditors' rights, and as such as may be limited
           by the exercise of judicial discretion in applying general principles
           of equity (regardless of whether the Notes are considered in a
           proceeding in equity or at law); it being understood, however, that
           the foregoing shall mean only that if there is a default in
           performance of an obligation (i) if a failure to pay or other damage
           can be shown and (ii) if the defaulting party can be brought into a
           court which will hear the case and apply the governing law, then,
           subject to the availability of defenses and the aforesaid exceptions,
           the court will provide a money damage (or perhaps injunctive or
           specific performance) remedy. The Notes conform in all material
           respects to the description thereof contained in the Prospectus under
           the caption "Description of the Notes" and conform in all material
           respects to the applicable provisions of the Indenture.

               (iii)  The Indenture has been duly qualified under the Trust
           Indenture Act, conforms in all material respects to the description
           thereof contained in the Prospectus under the caption "Description of
           the Notes," has been duly authorized and, when duly executed and
           delivered by the Company and the Trustee, will constitute a valid and
           binding instrument of the Company, enforceable against the Company in
           accordance with its terms, except as the enforceability thereof may
           be limited by bankruptcy, reorganization, insolvency, moratorium or
           other laws affecting creditors' rights, and as such as may be limited
           by the exercise of judicial discretion in applying general principles
           of equity (regardless of whether the Indenture is considered in a
           proceeding in equity or at law); it being understood, however, that
           the foregoing shall mean only that if there is default in performance
           of an obligation (i) if a failure to pay or other damage can be shown
           and (ii) if the defaulting party can be brought into a court which
           will hear the case and apply the governing law, then, subject to the
           availability of defenses and the aforesaid exceptions, the court will
           provide a money damage (or perhaps injunctive or specific
           performance) remedy.

               (iv)   The Indenture has been qualified under the Trust Indenture
           Act.

               (v)    The Registration Statement has become effective under the
           Act and, to the knowledge of such counsel, no Stop Order suspending
           the effectiveness of the Registration Statement has been issued, nor
           has any proceeding for the issuance of such an order been initiated
           or threatened by the Commission.

               (vi)   The Registration Statement and the Prospectus (other than
           the financial statements, supporting schedules and other financial
           and statistical data included therein or omitted therefrom, as to
           which no opinion need be rendered) comply in all material respects as
           to form with the requirements of the Act and the rules and
           regulations of the Commission thereunder and the Indenture complies
           in all material respects as to form with the Trust Indenture Act.

               (vii)  The summaries of the provisions of statutes and
           regulations included in the Company's Annual Report on Form 10-K for
           the year ended December 31, 1995 under the caption "Regulation" are,
           as of the date of filing of such report, in all material respects
           accurate summaries of the information purported to be summarized.

               (viii) The documents filed pursuant to the Exchange Act which are
           incorporated by reference in the Prospectus (except for any financial
           statements, schedules and other financial and statistical data
           included in or omitted from such documents, as to which such counsel
           need express no opinion), when they were filed with the Commission
           (or, if an amendment with respect to any such document was filed,
           when such amendment was filed), complied as to form in all material
           respects with the requirements of the Exchange Act and the rules and
           regulations of the Commission thereunder.

           Such counsel shall also state that, on the basis of such counsel's
participation in conferences with officers and other representatives of the
Company, the Company's auditors, the Subsidiaries, the Underwriters, and counsel
for the Underwriters at which the contents of the Registration Statement and the
Prospectus were discussed, (i) no facts have come to such counsel's attention
that have caused them to believe that the Registration Statement, at the time it
became effective with the Commission, contained an untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading or that the
Prospectus, at the time the Registration Statement became effective with the
Commission (unless the term "Prospectus" refers to a Rule 424(b) prospectus, in
which case at the time it was filed or transmitted to the Commission for filing)
and at the Closing Date, contained an untrue statement of a material fact or
omitted to state a material fact necessary in order to make the statements made,
in light of the circumstances under which they were made, not

                                      -20-
<PAGE>
 
misleading (except that they need express no view as to financial statements,
supporting schedules and other financial and statistical data included therein
or omitted therefrom) and (ii) such counsel does not know of any legal or
governmental proceedings pending or threatened against the Company, or any
Subsidiary, required to be described in the Prospectus which are not described
as required, nor of any material contracts of other documents of a character
required to be described in the Registration Statement or to be filed as an
exhibit to the Registration Statement by the Act, which have not been described
or filed (either physically or by incorporation by reference as permitted under
the Act), as required.

           In rendering such opinion, counsel for the Company may rely as to
matters of fact, to the extent they deem proper, on certificates of responsible
officers of the Company and the Subsidiaries. In rendering such opinion, such
counsel also may state that they express no opinion as to the laws of any
jurisdiction other than federal securities laws, federal banking, thrift and
thrift holding company laws and the General Corporation Law of the State of
Delaware. In addition, such counsel may state that they express no opinion as to
the application of any rating agency guidelines or initiatives.

           (d) That the Underwriters shall have received from Clifford M.
Sladnick, counsel to the Company, a favorable opinion dated the Closing Date and
satisfactory to the Underwriters and the Underwriters' counsel to the effect
that:

               (i)    Each of the Company and each Material Subsidiary has been
           duly organized and is validly existing as a corporation or federal
           savings bank in good standing under the laws of its jurisdiction of
           incorporation or charter; has the requisite corporate power to own,
           lease and operate its properties and conduct its business as
           described in the Registration Statement and each is duly qualified to
           do business as a foreign corporation or association under the
           corporation or banking law of, and is in good standing as such in,
           every jurisdiction wherein the ownership or leasing of its properties
           or the conduct of its business requires such qualification, except
           where the failure to be qualified or in good standing would not have
           a material adverse effect on the financial condition, business or
           prospects of the Company and its Subsidiaries taken as a whole. Each
           of the Material Subsidiaries is wholly-owned by the Company and the
           Material Subsidiaries are the Company's only direct subsidiaries.

               (ii)   The Company has the authorized capitalization set forth in
           the Prospectus. Each outstanding share of Common Stock of the Company
           and each outstanding share of capital stock of the Bank is duly
           authorized, validly issued, fully paid and non-assessable, has not
           been issued and is not owned or held in violation of any preemptive
           right of stockholders, and in the case of the Bank is owned of record
           and beneficially by the Company and, except as disclosed in the
           Registration Statement, is held free and clear of all liens, 

                                      -21-
<PAGE>
 
           claims, security interests, pledges, charges, encumbrances,
           stockholders' agreements, voting trusts or claims of others. Except
           as set forth in the Prospectus, there is no commitment, plan or
           arrangement to issue, and no outstanding option, warrant or other
           right calling for the issuance or sale of, any share of capital stock
           of the Company or of any Material Subsidiary or any security or other
           instrument which by its terms is convertible into, exercisable for or
           exchangeable for capital stock of the Company or of any Material
           Subsidiary. Except as described in the Registration Statement, there
           are no options, agreements, contracts or other rights in existence to
           purchase or acquire from any Material Subsidiary or the Company any
           issued and outstanding shares of the Common Stock of any Material
           Subsidiary.

               (iii)  The Bank is a federally chartered savings bank, duly
           authorized and with full corporate power to own its properties and
           carry on its business in all material respects as described in the
           Registration Statement. The Bank is a member in good standing of the
           Federal Home Loan Bank of Chicago and is an institution, the deposit
           accounts in which are insured to applicable limits by the Federal
           Deposit Insurance Corporation, and no proceedings for the termination
           or revocation of such membership or insurance are pending or, to the
           knowledge of such counsel, threatened.

               (iv)   The execution, delivery and performance of this Agreement,
           the Pricing Agreement and the Indenture, and the execution,
           authentication, issuance, sale, delivery and performance of the
           Notes, will not violate, conflict with, result in a breach of or
           (with or without the giving of notice or the passage of time or both)
           constitute a default under, the Company's certificate of
           incorporation or by-laws or any material indenture, mortgage, deed of
           trust or other instrument or agreement to which the Company or a
           Material Subsidiary is a party or by which it is bound, or any order,
           rule or regulation applicable to the Company or a Material Subsidiary
           of any court or other governmental authority, except where such would
           not have a material adverse effect on the financial condition,
           business or prospects of the Company and its Subsidiaries taken as a
           whole. The foregoing references to orders, rules or regulations shall
           not be deemed to include any orders, rules or regulations under
           federal or state securities laws, certain matters with respect to
           which are addressed elsewhere in this opinion.

               (v)    Such counsel does not know of (A) any pending or
           threatened litigation which would impair the enforceability of this
           Agreement or the Pricing Agreement, (B) any pending or threatened
           litigation or governmental proceedings against the Company or any
           Material Subsidiary required to be described in the Prospectus which
           are not so described, or (C) any contracts or documents required to
           be described in or filed as a part of the Registration Statement
           which are not so described or filed.

                                      -22-
<PAGE>
 
               (vi)   The Company meets the requirements for the use of Form S-3
           under the Act in connection with the offer and sale of the Notes. The
           Registration Statement and the Prospectus comply in all material
           respects as to form with the requirements of the Act and the Trust
           Indenture Act and, on the basis of such counsel's participation in
           conferences with representatives of the Company, the Company's
           auditors, the Subsidiaries, the Underwriters and counsel for the
           Underwriters at which conferences the contents of the Registration
           Statement, the Prospectus and each prospectus subject to completion
           and related matters were discussed, nothing has come to the attention
           of such counsel that causes such counsel to believe that the
           Registration Statement (including the documents incorporated by
           reference therein), at the time it became effective, at the time the
           Pricing Agreement was executed and at the Closing Date, contained or
           contains any untrue statement of a material fact or omitted or omits
           to state any material fact required to be stated therein or necessary
           to make the statements therein not misleading, or that the Prospectus
           (including the documents incorporated by reference therein), at the
           time the Registration Statement became effective (or, if applicable,
           at the time the Prospectus was first filed with the Commission
           pursuant to Rule 424(b)) and at the Closing Date, contained or
           contains any untrue statement of any material fact or omitted or
           omits to state any material fact required to be stated therein or
           necessary in order to make the statements made therein, in the light
           of the circumstances under which they were made, not misleading,
           except in each case as to the financial statements and schedules and
           other financial and statistical data contained therein, as to which
           such counsel need not express any opinion.

               (vii)  The statements in the Prospectus in the sections captioned
           "The Company," "Recent Developments," "Certain Regulatory Matters,"
           and "Description of Notes," in each case insofar as such statements
           reflect a summary of the legal matters or the documents referred to
           therein, fairly and accurately present the information called for by
           the Act in all material respects.

               (viii) The Bank's only direct subsidiaries are SPF Insurance
           Agency, Inc., St. Paul Securities, Inc., Managed Properties, Inc.,
           MPI Illinois Corporation, Community Finance Corporation, SPIC,
           EFS/San Diego Service Corporation, and EFS Service Corporation, each
           of which is wholly owned by the Bank and each of which has been duly
           organized and is validly existing as a corporation in good standing
           under the laws of the State of Illinois.

               (ix)   Investment Network, Inc. is the sole direct subsidiary of
           St. Paul Securities, Inc., Investment Network Advisors, Inc. is the
           sole subsidiary of Investment Network, Inc., and each of Investment
           Network, Inc. and Investment Network Advisors, Inc. have been duly
           organized and are validly

      9.   EFFECTIVE DATE OF AGREEMENT.
           ---------------------------

           (a) This Agreement shall become effective when notice of the
effectiveness of the Registration Statement has been released by the Commission
and the Pricing Agreement has been executed. Until such time as this Agreement
shall have become effective, it may be terminated by the Company by notifying
the Underwriters or by the Underwriters notifying the Company.

           (b) If any one or more of the Underwriters shall fail or refuse to

defaulting Underwriter

                                      -26-
<PAGE>
 
or Underwriters agreed but failed or refused to purchase is not more than one-
tenth of the aggregate principal amount of Notes, each non-defaulting
Underwriter shall be obligated, severally, in the proportion which the principal
amount of Notes set forth opposite its name in Schedule I bears to the aggregate
principal amount of Notes set forth opposite the names of all non-defaulting
Underwriters or in such other proportion as such non-defaulting Underwriters may
determine, to purchase the Notes which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase. If any Underwriter or
Underwriters shall fail or refuse to purchase Notes and the aggregate principal
amount of Notes with respect to which such default occurs is more than one-tenth
of the aggregate principal amount of Notes and arrangements satisfactory to the
non-defaulting Underwriters and the Company for the purchase of such Notes are
not made within 36 hours after such default, this Agreement will terminate
without liability on the part of any non-defaulting Underwriter or the Company.
In any such case which does not result in termination of this Agreement, either
the non-defaulting Underwriters or the Company shall have the right to postpone
the Closing Date, but in no event for longer than seven days, in order that the
required changes, if any, in the Registration Statement and the Prospectus or
any other documents or arrangements may be effected. Any action taken under this
paragraph shall not relieve any defaulting Underwriter from liability in respect
of any such default of any such Underwriter under this Agreement.

           (c) Any notice under this Section 9 may be made by any standard form
of written telecommunication or telephone but shall be subsequently confirmed by
letter.

      10.  TERMINATION OF AGREEMENT. This Agreement and the Pricing Agreement
           ------------------------
shall be subject to termination in the Underwriters' absolute discretion,
without liability on the part of any Underwriter to the Company, by notice given
to the Company, if after the date hereof and prior to the Closing Date (i)
trading in securities generally on the New York Stock Exchange, the American
Stock Exchange or the National Association of Securities Dealers Automated
Quotation System shall have been suspended or materially limited, (ii) a general
moratorium on commercial banking activities in the United States or in Illinois
shall have been declared by either federal or state authorities or (iii) there
shall have occurred any outbreak or escalation of hostilities or other
international or domestic calamity, crisis or change in political, financial or
economic conditions the effect of which on the financial markets of the United
States is such as to make it, in the Underwriters' judgment, impracticable or
inadvisable to market the Notes or to enforce contracts for the purchase of
Notes. Notice of such cancellation shall be given to the Company by any standard
form of written telecommunication or telephone but shall be subsequently
confirmed by letter.

      11.  MISCELLANEOUS.
           -------------

           (a) Except as otherwise provided in Sections 9 and 10 hereof, notice
given pursuant to any of the provisions of this Agreement shall be in writing

instruments of substantially similar tenor signed by such Holders in person or
by agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are received by 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 sometimes referred to as the "Act" of the Holders

writing, or the authority of the Person executing the same, may also be proved

anything done, omitted or suffered to be done by the Trustee or the Company in

Security.

any request, demand, authorization, direction, notice, consent or waiver or to
take any other Act authorized or permitted to be made, given or taken by the
Holders, but the Company shall have no obligation to do so.  If such a record
date is fixed, such request, demand, authorization, direction, notice, consent,
waiver or other Act may be given before, on or after such record date, but only
the Holders of record at the close of business on such record date (or their
duly designated proxies) shall be deemed to be Holders for the purposes of
determining whether Holders of the requisite proportion of Outstanding
Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that
purpose the Outstanding Securities shall be computed as of such record date.

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 or by 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

     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and mailed, first class postage prepaid, to the Company
     addressed to it at St. Paul Bancorp, Inc., 6700 West North Avenue, Chicago,

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 such Holder affected by such event, at his address as
it appears in the Register, within the time prescribed for the giving of such
notice.

     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 of Securities.  Any notice mailed to a Holder in
the manner herein

                                      -12-

prescribed shall be conclusively deemed to have been received by such Holder,
whether or not such Holder actually receives such notice.

     If by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice as provided above,

constitute a sufficient notification for every purpose hereunder.

     Any request, demand, authorization, direction, notice, consent, waiver or
other Act required or permitted under this Indenture shall be in the English
language.

     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 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.

delivery to the Trustee of an Officers' Certificate or in one or more indentures
supplemental hereto, in each case with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture.  Such Securities may have such letters, numbers or other marks of
identification and such legends or endorsements placed thereon as the Company
may deem appropriate and as are not inconsistent with this Indenture, or as may
be required to comply with the rules of any securities exchange, all as
determined by the officers executing such Securities as evidenced by their
execution of the Securities.  If temporary Securities of any series are issued
as permitted by Section 3.4, the form thereof also shall be established as
provided in the preceding sentences.  If the forms of Securities of any series
are established by an Officers' Certificate, such Officers' Certificate shall be
delivered to the Trustee at or prior to the delivery of the Company Order
contemplated by Section 3.3 for the authentication and delivery of such
Securities.

          The permanent Securities, if any, shall be printed, lithographed or
engraved or produced by any combination of these methods or may be produced in
any other manner, all as determined by the officers executing such Securities,
as evidenced by their execution of such Securities.

Section 3.2, any such Security shall represent such of the Outstanding
Securities of such series as shall be specified therein and may provide that it
shall represent the aggregate amount of Outstanding Securities from time to time
endorsed thereon and that the aggregate amount of Outstanding Securities
represented thereby may from time to time be reduced to reflect exchanges.  Any
endorsement of a Security in global form to reflect the amount, or any increase
or decrease in the amount, or changes in the rights of Holders, of Outstanding
Securities represented thereby, shall be made by the Trustee in such manner and
upon instructions given by such Person or Persons as shall be specified therein
or in the Company Order to be delivered to the Trustee pursuant to Section 3.3
or 3.4.  Subject to the provisions of Sections 3.3, 3.4 and 3.5, the Trustee
shall deliver and redeliver any Security in global form in the manner and upon
instructions given by the Person or Persons specified therein or in the
applicable Company Order.  Any instructions by the Company with respect to
endorsement or delivery or redelivery of a Security in global form shall be in
writing (which need not comply with Section 1.2 hereof and need not be
accompanied by an Opinion of Counsel).

     The provisions of the last paragraph of Section 3.3 shall apply to any
Security in global form if such Security was never issued and sold by the
Company and the Company delivers to the Trustee the Security in global form
together with written instructions (which need not comply with Section 1.2 and
need not be accompanied by an Opinion of Counsel) with regard to the reduction
or increase in the principal amount of Securities represented thereby, together
with the written statement contemplated by the last paragraph of Section 3.3.

     Every Security in global form authenticated and delivered hereunder shall
bear a legend in substantially the following form:

          (c) All Securities of any one series shall be substantially identical
except as to denomination and the rate or rates of interest, if any, and Stated
Maturity, the date from which interest, if any, shall accrue and except as may
otherwise be provided in or pursuant to an Officers' Certificate or a Board

All Securities of any one series need not be issued at the same time and, unless
otherwise provided, a series may be reopened, without the consent of the
Holders, for issuances of additional Securities of such series or for the
establishment of additional terms with respect to the Securities of such series.

          (d) If any of the terms of the Securities of any series are
established by action taken pursuant to a Board Resolution, a copy of such Board
Resolution shall be certified by the Corporate Secretary or an Assistant
Secretary of the Company and delivered to the Trustee at or prior to the

determining, the terms of the Securities of such series, and, if requested by
the Trustee, an appropriate record of any action taken pursuant thereto in
connection with the issuance of any Securities of such series shall be delivered
to the Trustee prior to the authentication and delivery thereof.  With respect
to Securities of a series subject to a Periodic Offering, such Board

                                      -19-

Resolution or Officers' Certificate may provide general terms for Securities of
such series and provide either that the specific terms of particular Securities
of such series shall be specified in a Company Order or that such terms shall be
determined by the Company, or one or more of the Company's agents designated in
an Officers' Certificate, in accordance with the Company Order as contemplated
by the first proviso of the third paragraph of Section 3.3.

Section 3.1, any Securities of a series shall be issuable in denominations of
$1,000 and any integral multiple thereof.

     Section 3.3  Execution, Authentication, Delivery and Dating.  Securities
                  ----------------------------------------------             
shall be executed on behalf of the Company by the Chairman, the President, any
Executive Vice President, any Senior Vice President or the Treasurer and
attested to by the Corporate Secretary or Assistant Secretary of the Company.
The Company's seal shall be affixed to the Securities, or a facsimile of such
seal shall be reproduced on the Securities.  The signatures of such 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 from time to time, 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 the delivery of such Securities,
and the Trustee in accordance with the Company Order shall authenticate and
deliver such Securities; provided, however, that in the case of Securities
                         --------  -------                                
offered in a Periodic Offering, the Trustee shall authenticate and deliver such
Securities from time to time in accordance with such other procedures
(including, without limitation, the receipt by the Trustee of oral or electronic
instructions from the Company or its duly authorized agents, thereafter promptly
confirmed in writing) acceptable to the Trustee as may be specified by or
pursuant to a Company Order delivered to the Trustee prior to the time of the
first authentication of Securities of such series.

     If the form or terms of the Securities of a series have been established by
or pursuant to one or more Officers' Certificates or one or more Board
Resolutions as permitted by Sections 2.1 and

                                      -20-

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 315(a) through (d)
of the Trust Indenture Act) shall be fully protected in relying upon, an Opinion
of Counsel stating,

          (1) that the forms and terms of such Securities have been established
     in conformity with the provisions of this Indenture; and

          (2) 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 customary exceptions;

provided, however, that, with respect to Securities of a series subject to a
- --------  -------                                                           
Periodic Offering, the Trustee shall be entitled to receive such Opinion of
Counsel only once at or prior to the time of the first authentication of
Securities of such series and that the Opinion of Counsel above may state:

          (x) that the forms of such Securities have been, and the terms of such
     Securities (when established in accordance with such procedures as may be
     specified from time to time in a Company Order, all as contemplated by and
     in accordance with a Board Resolution or an Officers' Certificate pursuant
     to Section 3.1, as the case may be) will have been, established in
     conformity with the provisions of this Indenture; and

          (y) that such Securities, when (1) executed by the Company, (2)
     completed, authenticated and delivered by the Trustee in accordance with
     this Indenture, and (3) 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 customary exceptions.

     With respect to Securities of a series subject to a Periodic Offering, the
Trustee may conclusively rely, as to the authorization by the Company of any of
such Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon such Opinion of Counsel and any other
documents delivered pursuant to Sections 2.1 and 3.1, as

                                      -21-
<PAGE>
 
applicable, at or prior to the time of the first authentication of Securities of
such series unless and until it has received written notification that such
opinion or other documents have been superseded or revoked.  In connection with
the authentication and delivery of Securities of a series subject to a Periodic
Offering, the Trustee shall be entitled to assume that the Company's
instructions to authenticate and deliver such Securities do not violate any
rules, regulations or orders of any governmental agency or commission having
jurisdiction over the Company.

     If the form or terms of the Securities of a series have been established by
or pursuant to one or more Officers' Certificates or one or more Board
Resolutions as permitted by Sections 2.1 and 3.1, the Trustee shall have the
right to decline to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will adversely affect the Trustee's own rights,
duties or immunities under this Indenture or otherwise in a manner which is not
reasonably acceptable to the Trustee.

     If all of the Securities of any series are not to be issued at one time, it
shall not be necessary to deliver the Officers' Certificate or the Board
Resolution otherwise required pursuant to Section 3.1 at or prior to the time of
the authentication of each Security of such series if such Officers' Certificate
or Board Resolution is delivered at or prior to the authentication upon original
issuance of the first Security of such series to be issued.

     If the Company shall establish pursuant to Section 3.1 that the Securities
of a series are to be issued in whole or in part in global form, then the
Company shall execute and the Trustee shall, in accordance with this Section and
the Company Order with respect to such series, authenticate and deliver one or
more Securities in global form that (i) shall represent and shall be denominated
in an amount equal to the aggregate principal amount of the initially issued
Outstanding Securities of such series to be represented by such Security or
Securities in global form, (ii) shall be registered in the name of the
Depositary for such Security or Securities in global form or the nominee of such
Depositary, and (iii) shall be delivered by the Trustee to such Depositary or
pursuant to such Depositary's instruction.

     Each Depositary designated pursuant to Section 3.1 for a Security in global
form must, at the time of its designation and at all times while it serves as
Depositary, be a clearing agency registered under the Securities Exchange Act of
1934, as amended, and any other applicable statute or regulation.  The Trustee

                                      -22-
<PAGE>
 
shall have no responsibility to determine if the Depositary is so registered.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefits 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 manual signature of one of the authorized signatories of the
Trustee or an Authenticating Agent.  Such signature upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered under this Indenture and is entitled to the benefits
of this Indenture.

     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 3.9 together with a written statement (which need not comply
with Section 1.2 and need not be accompanied by an Opinion of Counsel) stating
that such Security has never been issued and sold by the Company, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall not 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 Company Order, the
Trustee shall authenticate and deliver temporary Securities of such series which
are printed, lithographed, typewritten, mimeographed or otherwise produced, in
any authorized denomination, substantially of the tenor and form, of the
definitive Securities 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 conclusively evidenced by their
execution of such Securities.  In the case of Securities of any series, such
temporary Securities may be in global form.

     Except in the case of temporary Securities in global form, each of which
shall be exchanged in accordance with the provisions thereof, if temporary
Securities of any series are issued, the Company will cause permanent Securities
of such series to be prepared without unreasonable delay.  After preparation of
such permanent Securities, the temporary Securities shall be exchangeable for
such permanent Securities of like tenor upon surrender of the temporary
Securities of such series at the office or agency of the Company pursuant to
Section 9.2 in a Place of Payment for such series, without charge to the Holder.

                                      -23-
<PAGE>
 
surrender for cancellation of any one or more temporary Securities of any
series, the Company shall execute and the Trustee shall authenticate and deliver
in exchange therefor a like principal amount of permanent Securities of the same
series of authorized denominations and of like tenor.  Until so exchanged, the
temporary Securities of any series shall in all respects be entitled to the same
benefits under this Indenture as permanent Securities of such series except as
otherwise specified as contemplated by Section 3.1.

     Section 3.5  Registration, Registration of Transfer and Exchange.  The
                  ---------------------------------------------------      
Company shall cause to be kept at the Corporate Trust Office of the Trustee or
in any office or agency to be maintained by the Company in accordance with
Section 9.2 in a Place of Payment, a register (the "Register") in which, subject
to such reasonable regulations as it may prescribe, the Company shall provide
for the registration of Securities and the registration of transfers of
Securities.  The Register shall be in written form or any other form capable of
being converted into written form within a reasonable time.  The Trustee is
hereby initially appointed "Registrar" for the purpose of registering Securities
and transfers of Securities as herein provided.

     Upon surrender for registration of transfer of any Security of any series
at the office or agency maintained pursuant to Section 9.2 in a Place of Payment
for that series, 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 and of a
like aggregate principal amount and tenor.

     At the option of the Holder, Securities of any series (except a Security in
global form) may be exchanged for other Securities of the same series, of any
authorized denominations and of a like aggregate principal amount containing
identical terms and provisions, 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 which the Holder making the exchange is entitled to
receive.

     Notwithstanding any other provision of this Section, unless and until it is
exchanged in whole or in part for Securities in certificated form in the
circumstances described below, a Security in global form representing all or a
portion of the Securities of a series may not be transferred except as a whole
by the Depositary for such series to a nominee of such Depositary or by a
nominee of such Depositary to such Depositary or another nominee of such
Depositary or by such Depositary or any such nominee to a successor

                                      -24-
<PAGE>
 
Depositary for such series or a nominee of such successor Depositary.

     If at any time the Depositary for the Securities of a series notifies the
Company that it is unwilling or unable to continue as Depositary for the
Securities of such series or if at any time the Depositary for the Securities of
such series shall no longer be eligible under Section 3.3, the Company shall
appoint a successor Depositary with respect to the Securities of such series.
If a successor Depositary for the Securities of such series is not appointed by
the Company within 90 days after the Company receives such notice or becomes
aware of such ineligibility, the Company's election pursuant to Section
3.1(b)(15) shall no longer be effective with respect to the Securities of such
series and the Company shall execute, and the Trustee, upon receipt of a Company
Order for the authentication and delivery of certificated Securities of such
series of like tenor, shall authenticate and deliver Securities of such series
of like tenor in certificated form, in authorized denominations and in an
aggregate principal amount equal to the principal amount of the Security or
Securities of such series of like tenor in global form in exchange for such
Security or Securities in global form.

     The Company may at any time in its sole discretion determine that
Securities of a series issued in global form shall no longer be represented by
such a Security or Securities in global form.  In such event, the Company shall
execute, and the Trustee, upon receipt of a Company Order for the authentication
and delivery of certificated Securities of such series of like tenor, shall
authenticate and deliver, Securities of such series of like tenor in
certificated form, in authorized denominations and in an aggregate principal
amount equal to the principal amount of the Security or Securities of such
series of like tenor in global form in exchange for such Security or Securities
in global form.

     If specified by the Company pursuant to Section 3.1 with respect to a
series of Securities, the Depositary for such series may surrender a Security in
global form of such series in exchange in whole or in part for Securities of
such series in certificated form on such terms as are acceptable to the Company
and such Depositary.  Thereupon, the Company shall execute, and the Trustee
shall authenticate and deliver, without service charge,

     (i)  to each Person specified by such Depositary a new certificated
          Security or Securities of the same series of like tenor, of any
          authorized denomination as requested by such Person in aggregate
          principal amount equal to and in exchange for such Person's beneficial
          interest in the Security in global form; and

                                      -25-
<PAGE>
 
     (ii) to such Depositary a new Security in global form of like tenor in a
denomination equal to the difference, if any, between the principal amount of
the surrendered Security in global form and the aggregate principal amount of
certificated Securities delivered to Holders thereof.

     Upon the exchange of a Security in global form for Securities in
certificated form, such Security in global form shall be cancelled by the
Trustee.  Securities in certificated form issued in exchange for a Security in
global form pursuant to this Section shall be registered in such names and in
such authorized denominations as the Depositary for such Security in global
form, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee.  The Trustee shall deliver such
Securities to the Persons in whose names such Securities are so registered.

     All Securities issued upon any registration of transfer or upon any
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 registration of transfer or exchange.

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

     No service charge shall be made for any registration of transfer or for any
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 registration or transfer or exchange of Securities, other than
exchanges pursuant to Section 3.4, 8.6 or 10.7 not involving any transfer.

     The Company shall not be required (i) to issue, register the transfer of,
or exchange any Securities for a period beginning at the opening of business 15
days before the day of the mailing of a notice of redemption of Securities of
like tenor and of the series of which such Security is a part selected for
redemption under Section 10.3 and ending at the close of business on the day of
such mailing or (ii) to register the transfer of or exchange any Security so
selected for redemption, in whole or in part, except the unredeemed portion of
any Security being redeemed in part.

     Section 3.6  Replacement Securities.  If a mutilated Security is
                  ----------------------                             
surrendered to the Trustee, together with, in proper cases, such security or
indemnity as may be required by the Company or the Trustee to save each of them
and any agent of either of them harmless, the Company shall execute and the
Trustee shall authenticate and deliver a replacement Security of the same series
and principal amount and date of maturity, if the Trustee's requirements are
met.

     If there shall be delivered to the Company and 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 and
any agent of either 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 shall execute and the Trustee shall authenticate and
deliver in lieu of any such destroyed, lost or stolen Security a replacement
Security of the same series and principal amount, containing identical terms and
provisions as the destroyed, lost or stolen Security.

     In case 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, 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 or the Registrar) connected therewith.

     Every new Security of any series 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 that 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 3.7  Payment of Interest; Interest Rights Preserved.  (a) Unless
                  ----------------------------------------------             
otherwise specified as contemplated by Section 3.1, interest, if any, on any
Security which is payable, and is

                                      -27-
<PAGE>
 
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 at the office or agency maintained for such purpose pursuant
to Section 9.2; provided, however, that, at the option of the Company, interest
                --------  -------                                              
on any series of Securities that bear interest may be paid (i) by check mailed
to the address of the Person entitled thereto as it shall appear on the Register
of Holders of Securities of such series, or (ii) to the extent specified as
contemplated by Section 3.1, by wire transfer to an account maintained by the
Person entitled thereto as specified in the Register of Holders of Securities of
such series.

          (b) Unless otherwise specified as contemplated by Section 3.1, any
interest on any Security of any series which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of his 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 (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 of such series and the date of the proposed payment, and
     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 (1) 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
     Securities of

                                      -28-
<PAGE>
 
     such series at his address as it appears in the Register, not less than 10
     days prior to such Special Record Date.  Notice of the proposed payment of
     such Defaulted Interest and the Special Record Date therefor having been so
     mailed, such Defaulted Interest shall be paid to the Persons in whose names
     the Securities of such series (or their respective Predecessor Securities)
     are registered at the close of business on such Special Record Date and
     shall no longer be payable pursuant to the following clause (2).

          (2) The Company may make payment of any Defaulted Interest on the
     Securities of any series to the Persons in whose names the Securities of
     such series (or their respective Predecessor Securities) are registered at
     the close of business on a specified date in any other lawful manner not
     inconsistent with the requirements of any securities exchange on which such
     Securities may be listed, and upon such notice as may be required by such
     exchange, if, after notice given by the Company to the Trustee of the
     proposed payment pursuant to this clause (2), such manner of payment shall
     be deemed practicable by the Trustee.

          (c) Subject to the foregoing provisions of this Section and Section
3.5, each Security delivered under this Indenture upon registration of 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, which were carried by such other
Security.

     Section 3.8  Persons Deemed Owners.  Prior to due presentment of any
                  ---------------------                                  
Security for registration of transfer, the Company, the Trustee and any agent of
the Company or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of, premium, if any, and (subject to Sections 3.5 and 3.7) 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.  None of the Company, the Trustee or any
agent of the Company or the Trustee shall have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a Security in

                                      -29-
<PAGE>
 
global form, or for maintaining, supervising or reviewing any records relating
to such beneficial ownership interests.

     Section 3.9  Cancellation.  The Company at any time may deliver Securities
                  ------------                                                 
to the Trustee for cancellation.  The Registrar and any Paying Agent shall
forward to the Trustee any Securities surrendered to them for replacement, for
registration of transfer, or for exchange or payment.  The Trustee shall cancel
all Securities surrendered for replacement, for registration of transfer, or for
exchange, payment, redemption or cancellation and may dispose of cancelled
Securities and issue a certificate of destruction to the Company.  The Company
may not issue new Securities to replace Securities that it has paid or delivered
to the Trustee for cancellation, except as expressly permitted in the terms of
Securities for any particular series or as permitted pursuant to the terms of
this Indenture.

     Section 3.10  Computation of Interest.  Except as otherwise specified as
                   -----------------------                                   
contemplated by Section 3.1, interest on any Securities of a series that bear
interest shall be computed on the basis of a 360-day year of twelve 30-day
months.

     Section 3.11  CUSIP Numbers.  The Company in issuing the Securities may use
                   -------------                                                
"CUSIP" numbers (in addition to the other identification numbers printed on the
Securities), and, if so, the Trustee shall use "CUSIP" numbers in notices of
redemption as a convenience to Holders; provided, however, that any such notice
                                        --------  -------                      
may state that no representation is made as to the correctness of such "CUSIP"
numbers either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such "CUSIP" numbers.

Except as otherwise specified as contemplated by Section 3.1, this Indenture
shall upon a Company Request cease to be of further effect with respect to
Securities of or within any series (except as to any surviving rights of
registration of transfer or exchange of such Securities and replacement of such
Securities which may have been destroyed, lost, stolen or mutilated, as herein
expressly provided for) and the Trustee, at the expense of the Company, shall
execute proper instruments

                                      -30-
<PAGE>
 
acknowledging satisfaction and discharge of this Indenture with respect to such
Securities when:

          (1)  either

               (A) all such Securities previously authenticated and delivered
          (other than (i) such Securities which have been destroyed, lost or
          stolen and which have been replaced or paid as provided in Section
          3.6, and (ii) such 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 9.3) have been delivered to the Trustee for
          cancellation; or

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

                    (i)  have become due and payable, or

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

                    (iii)  if redeemable at the option of the Company, 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 (i), (ii) or (iii) above, has
          irrevocably deposited or caused to be deposited with the Trustee as
          trust funds in trust for the purpose, an amount sufficient to pay and
          discharge the entire indebtedness on such Securities not theretofore
          delivered to the Trustee for cancellation, for principal, premium, if
          any, and interest, with respect thereto, to the date of such deposit
          (in the case of Securities which 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 with respect to such Securities; and

          (3) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     herein provided for

                                      -31-
<PAGE>
 
     relating to the satisfaction and discharge of this Indenture as to such
     series have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture with respect to
any series of Securities, the obligation of the Company to the Trustee and any
predecessor Trustee under Section 6.9, the obligations of the Company to any
Authenticating Agent under Section 6.14 and, if money shall have been deposited
with the Trustee pursuant to subclause (B) of clause (1) of this Section, the
obligations of the Trustee under Section 4.2 and the last paragraph of Section
9.3 shall survive.

     Section 4.2  Application of Trust Funds.  Subject to the provisions of the
                  --------------------------                                   
last paragraph of Section 9.3, all money deposited with the Trustee pursuant to
Section 4.1 shall be held in trust and applied by it, in accordance with the
provisions of the Securities and this Indenture, to the payment, either directly
or through any Paying Agent (including the Company acting as its own Paying
Agent) as the Trustee may determine, to the Persons entitled thereto, of the
principal, premium, if any, and any interest for whose payment such money has
been deposited with or received by the Trustee, but such money need not be
segregated from other funds except to the extent required by law.

     Section 4.3  Applicability of Defeasance Provisions.  Unless otherwise
                  --------------------------------------                   
specified as contemplated by Section 3.1, the provisions of Sections 4.4 and
4.5, together with the provisions of Sections 4.6 through 4.8 inclusive, shall
be applicable to the Securities of or within a series.

     Section 4.4  Defeasance and Discharge.  The Company, at its option, shall
                  ------------------------                                    
be deemed to have been discharged from its obligations with respect to the
Securities of or within a series on and after the date the conditions set forth
in Section 4.6 are satisfied (hereinafter "defeasance").  For this purpose, such
defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by such Securities which shall thereafter be
deemed to be "Outstanding" only for the purposes this Article 4, and to have
satisfied all its other obligations under such Securities and this Indenture
insofar as such Securities are concerned (and the Trustee, at the expense of the
Company, shall on a Company Order execute proper instruments acknowledging the
same), except the following which shall survive until otherwise terminated or
discharged hereunder: (a) the rights of Holders of such Securities to receive,
solely from the trust funds described in Section 4.6(a) and as more fully set
forth in such Section, payments in respect of the principal of, premium, if any,
and interest, if any, on such Securities when such payments are due; (b) the
rights, powers,

                                      -32-
<PAGE>
 
trusts, duties and immunities of the Trustee hereunder; and (c) this Article 4.
Subject to compliance with this Article 4, the Company may exercise its option
under this Section notwithstanding the prior exercise of its option under
Section 4.5 with respect to such Securities.

     Section 4.5  Covenant Defeasance.  The Company, at its option, shall be
                  -------------------                                       
released from its obligations under Sections 7.1, 9.4, 9.5, 9.8, 9.9, 9.10,
9.11, 9.12 and 9.13 and, if specified pursuant to Section 3.1, its obligations
under any other covenants, with respect to such Securities on and after the date
the conditions set forth in Section 4.6 are satisfied (hereinafter "covenant
defeasance"), and such Securities shall thereafter be deemed to be not
"Outstanding" for the purposes of any request, demand, authorization, direction,
notice, consent, waiver or other Act of Holders (and the consequences of any
thereof) in connection with Sections 7.1, 9.4, 9.5, 9.8, 9.9, 9.10, 9.11, 9.12
and 9.13 or such other covenants, but shall continue to be deemed "Outstanding"
for all other purposes hereunder.  For this purpose, such covenant defeasance
means that, with respect to such Securities, the Company may omit to comply with
and shall have no liability in respect of any term, provision, condition or
limitation set forth in any such Section or such other covenants, whether
directly or indirectly, by reason of any reference elsewhere herein to any such
Section or such other covenants or by reason of any reference in any such
Section or such other covenants to any other provision herein or in any other
document or otherwise and such omission to comply shall not constitute a Default
or an Event of Default under Section 5.1(3) or 5.1(7) or otherwise, as the case
may be, but, except as specified above, the remainder of this Indenture and such
Securities shall be unaffected thereby.

     Section 4.6  Conditions to Defeasance or Covenant Defeasance.  The
                  -----------------------------------------------      
following shall be the conditions to application of Section 4.4 or Section 4.5
to any Securities of or within a series:

          (a) The Company shall have deposited or caused to be deposited
     irrevocably with the Trustee (or another trustee satisfying the
     requirements of Section 6.12 who shall agree to comply with, and shall be
     entitled to the benefits of, the provisions of Sections 4.3 through 4.8
     inclusive and the last paragraph of Section 9.3 applicable to the Trustee,
     for purposes of such Sections also a "Trustee") as trust funds in trust for
     the purpose of making the payments referred to in clauses (x) and (y) of
     this Section 4.6(a), specifically pledged as security for, and dedicated
     solely to, the benefit of the Holders of such Securities, with instructions

                                      -33-
<PAGE>
 
     to the Trustee as to the application thereof, (A) money in an amount, or
     (B) Government Obligations which through the payment of interest and
     principal in respect thereof in accordance with their terms will provide,
     not later than one day before the due date of any payment referred to in
     clause (x) or (y) of this Section 4.6(a), money in an amount or (C) a
     combination thereof in an amount, sufficient, in the opinion of a
     nationally recognized firm of independent certified public accountants
     expressed in a written certification thereof delivered to the Trustee, to
     pay and discharge, and which shall be applied by the Trustee to pay and
     discharge, (x) the principal of, premium, if any, and interest, if any, on
     such Securities on the Maturity of such principal or installment of
     principal or interest and (y) any mandatory sinking fund payments
     applicable to such Securities on the day on which such payments are due and
     payable in accordance with the terms of this Indenture and such Securities.
     Before such a deposit the Company may make arrangements satisfactory to the
     Trustee for the redemption of Securities at a future date or dates in
     accordance with Article 10 which shall be given effect in applying the
     foregoing.

          (b) Such defeasance or covenant defeasance shall not result in a
     breach or violation of, or constitute a Default or Event of Default under

     Company is a party or by which it is bound.

     after such date (it being understood that this condition shall not be
     deemed satisfied until the expiration of such period).

          (d) In the case of an exercise by the Company of its option under
     Section 4.4, the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel to the effect that (i) the Company
     has received from, or there has been published by, the Internal Revenue
     Service a ruling, or (ii) since the date of execution of this Indenture,
     there has been a change in the applicable Federal income tax law, in either
     case to the effect that, and based thereon such opinion shall confirm that,
     the Holders of such Securities will not recognize income, gain or loss for
     Federal income tax purposes as a result of such defeasance and will be
     subject to Federal income tax on the

                                      -34-

     same amount and in the same manner and at the same times, as would have
     been the case if such deposit, defeasance and discharge had not occurred.

          (e) In the case of an exercise by the Company of its option under
     Section 4.5, the Company shall have delivered to the Trustee an Opinion of
     Counsel to the effect that the Holders of such Securities will not
     recognize income, gain or loss for Federal income tax purposes as a result
     of such covenant defeasance and will be subject to Federal income tax on
     the same amounts, in the same manner and at the same times as would have

          (f) The Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent to the defeasance under Section 4.4 or the covenant defeasance
     under Section 4.5 (as the case may be) have been complied with and an
     Opinion of Counsel to the effect that either (i) as a result of a deposit
     pursuant to subsection (a) above and the related exercise of the Company's
     option under Section 4.4 or Section 4.5 (as the case may be), registration
     is not required under the Investment Company Act of 1940, as amended, by
     the Company, with respect to the trust funds representing such deposit or
     by the Trustee for such trust funds or (ii) all necessary registrations
     under said Act have been effected.

          (g) Such defeasance or covenant defeasance shall be effected in
     compliance with any additional or substitute terms, conditions or
     limitations which may be imposed on the Company in connection therewith as
     contemplated by Section 3.1.

     Section 4.7  Deposited Money and Government Obligations to be Held in

directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Holders of such Securities of
all sums due and to become due thereon in respect of principal, premium, if any,
and interest, if any, but such money need not be segregated from other funds
except to the extent required by law.

expressing their opinion that the contemplated action is permitted by Standard
No. 76 or the Commission, for transactions accounted for as extinguishment of
debt under the circumstances described in paragraph 3.c of Standard No. 76 or
any successor provision, and (ii) verifying the accuracy, after giving effect to
such action or actions, of the computations which demonstrate that the amounts
remaining to be earned on any Government Obligations deposited with the Trustee
pursuant to Section 4.6(a) will be, when taken together with any money deposited
with the Trustee pursuant to Section 4.6(a), sufficient for purposes of Section
4.6(a).

Default with respect to the Securities of any series at the time Outstanding
occurs and is continuing, the Trustee or the Holders of at least 33% in
aggregate principal amount of all of the Outstanding Securities of that series,

may declare the principal amount (or, if the Securities of that series are
Original Issue 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 and upon any such declaration such principal amount (or,
in the case of Original Issue Discount Securities, such specified amount) shall
be immediately due and payable.

     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 Trustee, may
rescind and annul such declaration and its consequences if all existing Defaults
and Events of Default with respect to Securities of that series, other than the
non-payment of the principal amount (or, in the case of Original Discount
Securities, such specified amount) of Securities of that series which have
become due solely by such declaration of acceleration, have been cured or waived
as provided in Section 5.7.  No such rescission shall affect any subsequent
Default or impair any right consequent thereon.

     period of 30 days, or

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

  the Company will, upon demand of the Trustee, pay to it, for the benefit of
the Holders of such Securities, the whole amount then due and payable on such
Securities for principal, premium, if any, and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium, if any, and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

     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.

Trustee or any Holder of any Securities to exercise any right or remedy accruing
upon an Event of Default shall impair any such right or remedy or constitute a
waiver of or an acquiescence in any such Event of Default.

     Section 5.7  Waiver of Past Defaults.  The Holders of a majority in
                  -----------------------                               
aggregate principal amount of Outstanding Securities of any series by notice to

a past Default or Event of Default with respect to that series and its
consequences except (i) a Default or Event of Default in the payment of the
principal of, premium, if any, or interest on any Security of such series or
(ii) in respect of a covenant or provision hereof

                                      -40-

which pursuant to Section 8.2 cannot be amended or modified without the consent
of the Holder of each Outstanding Security of such series adversely affected.
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.

     Section 5.8  Control by Majority.  The Holders of a majority in aggregate

principal amount of the Outstanding Securities of each 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 it
with respect to Securities of that series; provided, however, that (a) the
                                           --------  -------              
Trustee may refuse to follow any direction that conflicts with law or this
Indenture, (b) subject to the provisions of Article 6, the Trustee may refuse to
follow any direction that is unduly prejudicial to the rights of the Holders of
Securities of such series not joining in such direction, it being understood
that the Trustee shall have no duty to ascertain whether or not such actions or
forbearances are unduly prejudicial to such Holders or that would in the good
faith judgment of the Trustee have a substantial likelihood of involving the
Trustee in personal liability and (c) the Trustee may take any other action
deemed proper by the Trustee which is not inconsistent with such direction.

     Section 5.9  Limitation on Suits by Holders.  No Holder of any Security of

     Outstanding Securities of that series shall have made a 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 indemnity
     satisfactory to the Trustee against any loss, liability or expense to be,
     or which may be, incurred by the Trustee in pursuing the remedy;

          (5) during such 60-day period, the Holders of a majority in aggregate
     principal amount of the Outstanding Securities of that series has not given
     to the Trustee a direction inconsistent with such written request.

     No one or more Holders of the Securities of any series shall have any right

               (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

                                      -43-
<PAGE>
 
          such certificates or opinions which by any provision hereof are
          specifically required to be furnished to the Trustee, the Trustee
          shall be under a duty to examine the same to determine whether or not
          they conform to the requirements of this Indenture.

          (b) In case an Event of Default has occurred and is continuing with
     respect to the Securities of any series, the Trustee shall exercise such of
     the rights and powers vested in it by this Indenture with respect to the
     Securities of such series, and use the same degree of care and skill in
     their exercise, as a prudent person would exercise or use under the
     circumstances in the conduct of his 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 with respect to the Securities of
          any series in good faith in accordance with the direction of the
          Holders of a majority in principal amount of the Outstanding
          Securities of such series 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.

          (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 it 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.

          (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.

Indenture Act:

          (a) The Trustee may conclusively rely and shall be protected in acting

     bond, debenture, note 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 a Company Order (other than
     delivery of any Security to the Trustee for authentication and delivery
     pursuant to Section 3.3, which shall be sufficiently evidenced as provided
     therein) 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) Before the Trustee acts or refrains from acting, the Trustee may
     consult with counsel of its selection and the written advice of such
     counsel or any Opinion of Counsel shall be full and complete authorization
     and protection in respect of any action taken, 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 which 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, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts

                                      -45-
<PAGE>
 
     or matters as it may see fit, and, if the Trustee shall determine to make
     such further inquiry or investigation, it shall be entitled to examine the
     books, records and premises of the Company, personally or by agent or
     attorney, at the Company's expense.

          (g) The Trustee may act through agents or attorneys and shall not be
     responsible for the misconduct or negligence of any agent or attorney
     appointed with due care by it hereunder.
    
          (h) The Trustee shall not be charged with knowledge of any Default or
     Event of Default with respect to the Securities of any series for which it
     is acting as Trustee unless either (i) a Responsible Officer of the Trustee
     shall have "actual knowledge" of the Default or Event of Default, or (ii)
     written notice of such Default or Event of Default shall have been given to
     the Trustee by the Company or by any Holder of Securities of that series or
     any other series, or, in the event of a default pursuant to Section 5.1(4),
     by the holder of any other indebtedness of the Company or by the trustee of
     any other agreement or instrument to which the Company is a party. As used
     herein, the term "actual knowledge" means the actual fact or state of
     knowing, without any duty to make any investigation or inquiry with regard
     thereto.       

          (i) The Trustee shall not be liable for any action it takes or omits
     to take in good faith which it believes to be authorized or within its
     rights or powers conferred on it by this Indenture.

          (j) The Trustee shall not be required 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 its rights or powers, if it 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.

     Section 6.3  Trustee May Hold Securities.  The Trustee, any Paying Agent,
                  ---------------------------                                 
any 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

                  -------------------                                     
hereunder need not be segregated from other funds except

the Securities, except the Trustee's certificates of authentication, shall be

occurs, transmit, in the manner and to the extent provided in Section 313(c) of
the Trust Indenture Act, notice of all uncured or unwaived Defaults known to it;
                                                                                
provided, however, that, except in the case of a Default in payment on the

Securities of any series, the Trustee may withhold the notice if and so long as
the board of directors, the executive committee or a trust committee of its
directors and/or its Responsible Officers in good faith determines that
withholding such notice is in the interests of Holders of Securities of that
series; provided further, however, that, in the case of any default or breach of
        -------- -------  -------                                               
the character specified in Section 5.1(3) with respect to the Securities of such

January 31 of each year commencing with the first January 31 after the first

mail to all Holders of Securities as provided in Section 313(c) of the Trust
Indenture Act a brief report dated as of such January 31, if required by Section
313(a) of the Trust Indenture Act.  The Trustee also shall comply with Sections

Company.  The Company will notify the Trustee when any series of Securities are
listed on any stock exchange.

     Section 6.8  Securityholder Lists.  The Trustee shall preserve in as
                  --------------------                                   
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Holders of Securities of each series.  If the
Trustee is not the

                                      -47-
<PAGE>
 
Registrar, the Company shall furnish to the Trustee semiannually on or before
the last day of June and December in each year, and at such other times as the
Trustee may request in writing, a list, in such form and as of such date as the
Trustee may reasonably require, containing all the information in the possession

     Section 6.9  Compensation and Indemnity.  (a) The Company shall pay to the
                  --------------------------                                   
Trustee from time to time such compensation as shall be agreed between the
Company and the Trustee for all services rendered by it hereunder.  The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust.  The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred by it in connection
with the performance of its duties under this Indenture, except any such expense
as may be attributable to its negligence or bad faith.  Such expenses shall
include the reasonable compensation and expenses of the Trustee's agents and
counsel.

     (b) The Company shall indemnify the Trustee for and hold it harmless
against, any loss or liability incurred by it without negligence or bad faith on
its part arising out of or in connection with its acceptance or administration
of the trust or trusts hereunder.  The Trustee shall notify the Company promptly
of any claim for which it may seek indemnity.  The Company shall defend the
claim and the Trustee shall cooperate in the defense.  The Trustee may have
separate counsel and the Company shall pay the reasonable fees and expenses of
such counsel.  The Company need not pay for any settlement made without its
consent, which consent shall not be unreasonably withheld or delayed.

     (c) The Company need not reimburse any expense or indemnify against any
loss or liability incurred by the Trustee through negligence or bad faith.

     (d) To secure the payment obligations of the Company pursuant to this
Section, the Trustee shall have a lien prior to the Securities of any series on

     (e) When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 5.1(5) or Section 5.1(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the

                                      -48-

services are intended to constitute expenses of administration under any
applicable Federal or state bankruptcy, insolvency or other similar law.

     (f) The provisions of this Section shall survive the termination of this
Indenture.

     Section 6.10  Replacement of Trustee.  (a) The resignation or removal of
                   ----------------------                                    
the Trustee and the appointment of a successor Trustee shall become effective
only upon the successor Trustee's acceptance of appointment as provided in
Section 6.11.

     (b) The Trustee may resign at any time with respect to the Securities of
any series by giving written notice thereof to the Company.  If the instrument
of acceptance by a successor Trustee required by Section 6.11 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 Holders of a majority in aggregate principal amount of the
Outstanding Securities of any series may remove the Trustee with respect to that
series by so notifying the Trustee and the Company and may appoint a successor
Trustee for such series with the Company's consent.

     (d)  If at any time:

          (1) the Trustee fails to comply with Section 310(b) of the Trust
     Indenture Act with respect to the Securities of a series after written
     request therefor by the Company or by any Holder of a Security of such
     series who has been a bona fide Holder of a Security of such series for at
     least six months, or

          (2) the Trustee with respect to the Securities of any series shall
     cease to be eligible under Section 310(a) of the Trust Indenture Act and
     shall fail to resign after written request therefor by the Company or by
     any Holder of a Security of such series who has been a bona fide Holder of
     a Security of such series for at least six months; or

          (3) the Trustee with respect to the Securities of any series becomes
     incapable of acting, is adjudged a bankrupt or an insolvent or a receiver
     or public officer takes charge of the Trustee or its property or affairs
     for the purpose of rehabilitation, conservation or liquidation,

                                      -49-
<PAGE>
 
then, in any such case, (i) the Company by or pursuant to a Board Resolution may
remove the Trustee with respect to all Securities, or (ii) subject to Section
315(e) of the Trust Indenture Act, any Holder who has been a bona fide Holder of
a Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the removal of the Trustee with respect to all Securities of such series and the
appointment of a successor Trustee or Trustees.

     (e) If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, with respect to Securities of one or more
series, the Company, by or pursuant to Board Resolution, shall promptly appoint
a successor Trustee with respect to the Securities of that or those series (it
being understood that any such successor Trustee may be appointed with respect
to the Securities of one or more or all of such series and that at any time
there shall be only one Trustee with respect to the Securities of any particular
series) and shall comply with the applicable requirements of Section 6.11.  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
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 in accordance with the
applicable requirements of Section 6.11, become the successor Trustee with
respect to the Securities of such series and to that extent 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 required by
Section 6.11, any Holder who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself 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.

     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 shall execute, acknowledge and deliver to the
Company and to the retiring Trustee an instrument accepting such appointment.
Thereupon, the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee, without 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

                                      -50-
<PAGE>
 
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 such successor Trustee shall execute and deliver an
indenture supplemental hereto wherein such successor Trustee shall accept such
appointment and which (i) shall contain such provisions as shall be necessary or
desirable to transfer and confirm to, and to vest in, such 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, (ii) 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 (iii) 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 as 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 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 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 such rights, powers and trusts referred to in
paragraph (a) or (b) of this Section, as the case may be.

                                      -51-
<PAGE>
 
     (d) No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under the
Trust Indenture Act and this Article.

     (e) 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 in the manner
provided for notices to the Holders of Securities in Section 1.6.  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 6.12  Eligibility; Disqualification.  There shall at all times be a
                   -----------------------------                                
Trustee hereunder which shall be eligible to act as Trustee under Section 310(a)
of the Trust Indenture Act.  If a corporation publishes reports of condition at
least annually, pursuant to law or the requirements of Federal, State,
Territorial or District of Columbia supervising or examining authority, then for
the purposes of Section 310(a)(2) of 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.  If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner
and with the effect specified in this Article.

     Section 6.13  Merger, Conversion, Consolidation or Succession to Business.
                   -----------------------------------------------------------  
Any corporation into which the Trustee may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any corporation
succeeding to all or substantially all the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such
corporation 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 with the same
effect as if such successor Trustee had itself authenticated such Securities.

     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

                                      -52-
<PAGE>
 
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon original issue, exchange, registration of transfer or partial
redemption thereof, 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.  Any such appointment shall be
evidenced by an instrument in writing signed by a Responsible Officer of the
Trustee, a copy of which instrument shall be promptly furnished to the Company.
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 and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent.  Each
Authenticating Agent shall be acceptable to the Company and, except as may
otherwise be provided pursuant to Section 3.1, shall at all times be a bank or
trust company or corporation organized and doing business and in good standing
under the laws of the United States of America or of any State or the District
of Columbia, authorized under such laws to act as Authenticating Agent, having a
combined capital and surplus of not less that $1,500,000 and subject to
supervision or examination by Federal or State authorities.  If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or the requirements of the aforesaid 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.  In case 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 corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate agency or corporate trust business of an Authenticating Agent,
shall continue to be an Authenticating Agent, provided such corporation shall be

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 will
give prompt written notice to the Trustee of the location and any change in the
location of any such office or agency.  If at any time the Company shall fail to

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

     The Company may also from time to time designate one or more other offices

     Unless otherwise specified as contemplated by Section 3.1, the Trustee

if any, or interest so becoming due, such sum to be held in trust for the
benefit of the Persons entitled to such principal, premium or interest, and

this Section, that such Paying Agent will:

          (1) hold all sums held by it for the payment of the principal of,
     premium, if any, or interest on Securities of that 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 the Securities of that series) in the making of any
     payment of principal, premium, if any, or interest on the Securities; and

          (3) at any time during the continuance of any such Default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such 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 a 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 any

                                      -61-

unclaimed for two years after such principal, premium, if any, or interest has
become due and payable shall be paid to the Company on a Company Request, or (if
then held by the Company) shall 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 City of Chicago, Illinois, or cause to be mailed to such
Holder, 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.

abandonment or termination of any right or franchise of the Company if, in the
determination of the Company, such abandonment or termination is in the best
interests of the Company and does not materially adversely affect the ability of
the Company to operate its business or to fulfill its obligations hereunder.

                  -------------------                                         
or guarantee any indebtedness for borrowed money (referred to in this Section
9.9 as "indebtedness") secured by a mortgage, encumbrance, security interest,
pledge, lien or charge (referred to in this Section 9.9 as a "pledge" or
"pledges") of or upon any property of the Company whether such property is owned
at the date of this Indenture or thereafter acquired, without making effective
provision whereby the Securities (together with, if the Company shall so
determine, any other indebtedness issued, assumed or guaranteed by the Company
and then existing or thereafter created) shall be secured by such pledge equally
and ratably with (or, at the option of the Company, prior to) such indebtedness,
so long as such indebtedness shall be so secured; provided, however, that the
                                                  --------  -------          
foregoing shall not apply to any of the following:

          (1)  pledges upon any shares of capital stock or indebtedness acquired
     by the Company after the date of this Indenture (A) to secure the payment
     of all or any part of the purchase price of such shares of capital stock or
     indebtedness upon the acquisition thereof by the Company, or (B) to secure
     any indebtedness issued, assumed or guaranteed by the Company prior to, at
     the time of, or within 360 days after the acquisition of such shares of
     capital stock or indebtedness, which indebtedness is issued, assumed or
     guaranteed for the purpose of financing or refinancing all or any part of
     the purchase price of such shares of capital stock or indebtedness;

          (2)  pledges of or upon shares of capital stock or indebtedness, which
     pledges exist at the time of acquisition of such shares or indebtedness by
     the Company;

          (3)  pledges of or upon any property of a corporation, which pledges
     exist at the time such corporation is merged

                                      -64-
<PAGE>
 
     with or into or consolidated with the Company or which pledges exist at the
     time of a sale or transfer of the properties of a corporation as an
     entirety or substantially as an entirety to the Company;

          (4)  mortgages existing on the date of execution of this Indenture;
     and

          (5)  any extension, renewal, substitution, refinancing, refunding or
     replacement (or successive extensions, renewals, substitutions,
     refinancings, refundings or replacements) (each a "refinancing") in whole
     or in part of any pledge existing at the date of the Indenture or any
     pledge referred to in the foregoing clauses (1) through (4), inclusive,

     the time of the refinancing plus the aggregate amount of premiums, other
     payments, costs and expenses required to be paid or incurred in connection
     with the refinancing, and that the refinancing shall be limited to all or a
     part of the shares of capital stock or indebtedness which was subject to
     the pledge so extended, renewed, substituted, refinanced, refunded or
     replaced.

     (b) Notwithstanding the provisions of subsection (a) of this Section, the
Company may, without equally and ratably securing the Securities, issue, assume
or guarantee indebtedness secured by a pledge not excepted by clauses (1)
through (5), so long as after giving effect thereto, the Company will own at
least 80% of the capital stock of all of its Material Subsidiaries then issued
and outstanding, free and clear of any pledge.

     Section 9.10  Ownership of Material Subsidiary Stock.  The Company
                   --------------------------------------              
covenants that it will not take any action which would result in a decrease in
the percentage of the outstanding shares of voting stock of any Material
Subsidiary directly or indirectly owned by the Company, except as the result of
(1) the issuance of directors' qualifying shares, (2) the declaration and
payment of patronage refunds,  (3) the purchase or retirement of shares with the
proceeds of newly issued shares, or (4) the sale of capital stock at a price
determined by the Company (which determination may be evidenced by a resolution
of the Company's Board of Directors) to be the fair value thereof.

                   ----------------------------

reasonable terms taking into account the nature of the Company's or the
Subsidiary's business.

covenants that it will not:

     pledge or otherwise dispose of any shares of capital stock of any class of
     a Bank or any securities convertible or exchangeable into shares of capital
     stock of any class of a Bank unless after giving effect to such transaction
     and to shares issuable upon conversion or exchange of outstanding
     securities convertible or exchangeable into such capital stock (including
     such securities, if any, which may be the subject of such transaction), at
     least 80% of the outstanding shares of capital stock of each class of such
     Bank shall be owned at that time by the Company; or

          (2)  permit a Bank to merge or consolidate or convey or transfer all

     stock of each class (after giving effect to such transaction and to shares
     issuable upon conversion or exchange of outstanding securities convertible
     or exchangeable into capital stock, including such securities, if any,
     which may be issued in such transaction) of the surviving corporation in
     the case of a merger or consolidation or of the transferee corporation in
     the case of a conveyance or transfer, shall be owned at that time by the
     Company.

     Section 9.13  Waiver of Certain Covenants.  The Company may fail or omit in
                   ---------------------------                                  
any particular instance to comply with the covenants set forth in this Article

Securities if the Company shall have obtained and filed with the Trustee prior
to the time for such compliance the consent in writing of the Holders of at
least a majority in aggregate principal amount of all of the Securities of such
series at the time Outstanding either waiving such compliance in such instance
or generally waiving compliance with such covenant or covenants, but no such
waiver shall extend to or affect any obligation not expressly waived or impair
any right consequent thereon.

their terms and (except as otherwise specified as contemplated by Section 3.1
for Securities of any series) in accordance with this Article.

                   -------------------------------------                      
Company to redeem any Securities shall be evidenced by or pursuant to a Board
Resolution or an Officers' Certificate.  In the case of any redemption at the

Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date, of the principal amount of Securities of
such series to be redeemed and, if applicable, of the tenor of the Securities to
be redeemed.  In the case of any redemption of Securities (a) prior to the
expiration of any restriction on such redemption provided in the terms of such

Trustee shall deem fair and appropriate.  The Trustee shall make the selection
from the Securities of the series that are Outstanding and that have not
previously been called for redemption and may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.

     The Trustee shall promptly notify the Company and the Registrar in writing
of the Securities selected by the Trustee for redemption and, in the case of any
Securities selected for partial redemption, the principal amount thereof to be
redeemed.

     principal amounts) of the particular Security or Securities to be redeemed;

          (4) in case any Security is to be redeemed in part only, the notice
     which relates to such Security shall state that on and after the Redemption
     Date, upon surrender of such Security, the Holder will receive, without a
     charge, a new Security or Securities of such series of authorized
     denominations for the principal amount thereof remaining unredeemed;

          (5) the Place or Places of Payment where such Securities maturing
     after the Redemption Date are to be surrendered for payment for the
     Redemption Price;

          (6) that Securities of the series called for redemption must be

          (7) that, on the Redemption Date, the Redemption Price will become due
     and payable upon each such Security, or the portion thereof, to be redeemed

provided in Section 9.3) an amount of money sufficient to pay on the Redemption
Date the Redemption Price of, and (unless the Redemption Date shall be an
Interest Payment Date) interest accrued to the Redemption Date on, all
Securities or portions thereof which are to be redeemed on that date.

Redemption Date, become due and payable at the Redemption Price therein
specified, and from and after such date (unless the Company shall default in the
payment of the Redemption Price and accrued interest) such Securities shall
cease to bear interest.  Upon surrender of any such Security for redemption in
accordance with said notice, such Security shall be paid by the Company at the
Redemption Price, together with accrued interest to the Redemption Date;

that Security, without service charge, a new Security or Securities of the same
series, the same form and the same Maturity in any authorized denomination equal

operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

               relating to the issuance and sale of the Notes and arrangements
               in connection therewith. 

          In our examination of the aforesaid documents, we have assumed the 
genuineness of all signatures, the legal capacity of natural persons, the 
authenticity, accuracy and completeness of all documents submitted to us, and 
the conformity with the original documents of all documents submitted to us as

          This opinion letter is based as to matters of law solely on the 
General Corporation Law of the State of Delaware and the contract law of the 
State of Illinois (but not including any statutes, ordinances, administrative 
decisions, rules or regulations of any political subdivision of the State of 
Illinois). We express no opinion herein as to any other laws, statutes, 
regulations, or ordinances.

opinion that following (i) final action of the Board of Directors of the Company

by bankruptcy, insolvency, reorganization, moratorium or other laws affecting 
creditors' rights (including, without limitation, the effect of statutory and 
other law regarding fraudulent conveyances, fraudulent transfers and 
preferential transfers) and as may be limited by the exercise of judicial 
discretion and the application of principles of equity including, without 
limitation, requirements of good faith, fair dealing, conscionability and 
materiality (regardless of whether the Notes are considered in a proceeding in 
equity or at law).

          The opinion expressed above shall be understood to mean only that if
there is a default in performance of an obligation, (i) if a failure to pay or
other damage can be shown and (ii) if the defaulting party can be brought into a
court which will hear the case and apply the governing law, then, subject to the
availability of defenses, and to the exceptions set forth above, the court will
provide a money damage (or perhaps injunctive or specific performance) remedy.

subsequent to the delivery of this opinion letter. This opinion letter has been 
prepared solely for your use in connection with the filing of the Registration
