  The Junior Subordinated Deferrable Interest Debentures, Series A (the
"Subordinated Debentures"), of NIPSCO Capital Markets, Inc. ("Capital") will
mature on             , 2026. Interest on the Subordinated Debentures is
payable quarterly in arrears on March 31, June 30, September 30 and December 31
of each year, beginning March 31, 1996, provided that, so long as an Event of
Default (as defined herein) has not occurred and is not continuing, Capital has
the right to extend the interest payment period at any time and from time to
time on the Subordinated Debentures to a period not exceeding 20 consecutive
quarters. The Subordinated Debentures will be redeemable at the option of
Capital, in whole or in part, on or after             , 2006 at the redemption
prices set forth herein. See "Description of the Subordinated Debentures --
Optional Redemption."
 
  The Subordinated Debentures will be represented by a Global Security or
Securities that will be deposited with, or on behalf of, The Depository Trust
Company ("DTC"). The Subordinated Debentures will be available for purchase in
denominations of $1,000 and any integral multiple thereof. See "Description of
the Subordinated Debentures."
 
  The Subordinated Debentures are unsecured debt obligations of Capital and are
entitled to the benefits of a Support Agreement, dated as of April 4, 1989, as
amended (the "Support Agreement"), between Capital and its parent company,
NIPSCO Industries, Inc. ("Industries"), providing for the payment of principal
of, and premium, if any, and interest on, the Subordinated Debentures in the
event of default of Capital. Payment of the principal of, and premium, if any,
and interest on, the Subordinated Debentures is subordinate and subject in
right of payment to the prior payment in full of all Senior Indebtedness of
Capital. As of September 30, 1995, outstanding Senior Indebtedness of Capital
aggregated approximately $69.2 million.

                             AVAILABLE INFORMATION
 
  Capital and Industries have filed with the Securities and Exchange
Commission (the "Commission") a registration statement on Form S-3 (including
any amendments thereto, the "Registration Statement") under the Securities Act
of 1933, as amended (the "Securities Act"), with respect to the Subordinated
Debentures. This Prospectus does not contain all of the information set forth
in the Registration Statement and the exhibits and schedules thereto, certain
portions of which have been omitted pursuant to the rules of the Commission.
Statements made in this Prospectus as to the contents of any contract,
agreement or other document are not necessarily complete. With respect to each
such contract, agreement or other document filed or incorporated by reference
as an exhibit to the Registration Statement, reference is made to such exhibit
for a more complete description of the matter involved, and each such
statement is qualified in its entirety by such reference.
 
  Industries is subject to the informational requirements of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and in accordance
therewith files reports, proxy statements and other information with the
Commission. Reports, proxy statements and other information filed by
Industries with the Commission may be inspected and copied at the public
reference facilities maintained by the Commission at Room 1024, 450 Fifth

Industries' securities are listed.
 
  On September 25, 1992, the staff of the Commission informed Industries and
Capital by letter that it would not recommend enforcement action to the
Commission if Capital did not file periodic reports pursuant to Sections 13
and 15(d) of the Exchange Act, subject to Industries' compliance with the
conditions set forth therein. In reliance upon such letter, no documents have
been filed or will be filed by Capital under the Exchange Act. Capital does
not intend to issue any periodic or other reports to holders of the
Subordinated Debentures. Capital has been advised by the Commission's staff
that financial information regarding Capital need not be included in any
registration statement on Form S-3 filed by Capital and Industries with
respect to the Subordinated Debentures and the Support Agreement.

                                 RISK FACTORS
 
  Prospective purchasers of Subordinated Debentures should carefully review
the information contained elsewhere in this Prospectus and should particularly
consider the following matters:
 
RIGHT OF CAPITAL TO DEFER PAYMENT OF INTEREST
 
  So long as Capital shall not be in default in the payment of interest on the
Subordinated Debentures, Capital shall have the right under the Indenture (as
defined below) to extend the interest payment period at any time and from time
to time for a period not exceeding 20 consecutive calendar quarters. No
interest shall be due and payable during an Extension Period (as defined
below), but on the interest payment date occurring at the end of each
Extension Period Capital shall pay to the holders of record on the record date
for such interest payment date (regardless of who the holders of record may
have been on other dates during the Extension Period) all accrued and unpaid
interest on the Subordinated Debentures, together with interest thereon,
compounded quarterly at the rate of interest on the Subordinated Debentures.
In the event that Capital exercises such right to extend, Capital may not
declare or pay dividends on, or redeem, purchase or acquire, any shares of its
capital stock until deferred interest on the Subordinated Debentures is paid
in full, subject to certain exceptions described herein.
 
  Upon the termination of any Extension Period and the payment of all interest
then due, Capital may commence a new Extension Period. Capital may also prepay
at any time all or a portion of the interest accrued during an Extension
Period. Consequently, there could be multiple Extension Periods of varying
lengths throughout the term of the Subordinated Debentures. See "Description
of the Subordinated Debentures--Option to Extend Interest Payment Period."
 
  Capital has no present intention of exercising its right to defer payments
of interest by extending the interest payment period on the Subordinated
Debentures.
 
NO CASH PAYMENTS DURING EXTENSION PERIOD TO PAY ACCRUED TAX LIABILITY
 
  In the event an Extension Period occurs, holders of the Subordinated
Debentures would continue, under the original issue discount rules, to accrue
income on the Subordinated Debentures for United States federal income tax
purposes. As a result, a holder that is subject to United States federal
income tax ordinarily would include such amounts in gross income in advance of
the receipt of cash. A holder that disposes of its Subordinated Debentures
prior to the record date for payment of interest at the end of an Extension
Period will not receive cash from Capital related to such interest because
such interest will be paid to the holder of record on such record date,
regardless of who the holders of record may have been on other dates during
the Extension Period. The extent to which such a holder will receive a return
on the Subordinated Debentures for the period it held such Subordinated
Debentures will depend on the market for the Subordinated Debentures at the
time of such disposition. See "Differences in Timing and Amount Between
Interest Payments and Taxable Income" below and "Certain Federal Income Tax
Considerations."
 
CERTAIN TRADING CHARACTERISTICS
 
  The Subordinated Debentures are expected to trade in the market as equity
securities. Accordingly, the Subordinated Debentures are expected to trade
"flat"; thus, purchasers of Subordinated Debentures will not pay and sellers
will not receive any accrued and unpaid interest thereon that is not included
in the trading price. However, for United States federal income tax purposes,
interest on the Subordinated Debentures is included in income as it accrues,
rather than when it is paid. See "Certain Federal Income Tax Considerations."
 
DIFFERENCES IN TIMING AND AMOUNT BETWEEN INTEREST PAYMENTS AND TAXABLE INCOME
 
  Because the original issue discount rules apply to the Subordinated
Debentures, even if an Extension Period does not occur there may be
differences in timing and amount between the gross income recognized with
respect
 
                                       4
<PAGE>
 
to a Subordinated Debenture and the interest payable on such Subordinated
Debenture. An owner of a Subordinated Debenture that does not use a calendar
year for tax accounting may be required to include in income in each tax year
original issue discount corresponding to a portion of the interest payable
during such owner's next succeeding tax year. An owner that disposes of its
Subordinated Debentures may be required to include in income original issue
discount corresponding to interest payable after the disposition. See "Certain
Federal Income Tax Considerations."
 
POTENTIAL MARKET VOLATILITY DURING EXTENSION PERIOD
 
  As described above, Capital has the right to extend an interest payment
period from time to time for a period not exceeding 20 consecutive calendar
quarters. In the event Capital determines to extend an interest payment
period, or in the event Capital thereafter extends an Extension Period or
prepays interest accrued during an Extension Period as described above, the
market price of the Subordinated Debentures is likely to be adversely
affected. In addition, as a result of such rights, the market price of the
Subordinated Debentures may be more volatile than other debt instruments with
original issue discount that do not have such rights. A holder that disposes
of its Subordinated Debentures during an Extension Period, therefore, may not
receive the same return on its investment as a holder that continues to hold
its Subordinated Debentures. See "Description of the Subordinated Debentures--
Option to Extend Interest Payment Period."
 
SUBORDINATION OF SUBORDINATED DEBENTURES
 
  The Subordinated Debentures are senior to the capital shares of Capital, but
will be unsecured obligations of Capital and subordinate to all existing and
future Senior Indebtedness of Capital. On September 30, 1995, approximately
$69.2 million of such Senior Indebtedness was outstanding. There are no terms
of the Subordinated Debentures that limit Capital's ability to incur
additional indebtedness, including indebtedness that would rank senior to the
Subordinated Debentures. The Indenture does not contain any cross-defaults to
any other indebtedness of Capital or Industries and, therefore, a default with
respect to, or the acceleration of, any such other indebtedness will not
constitute an Event of Default (as defined in the Indenture) with respect to
the Subordinated Debentures. Moreover, because the obligor under the Support
Agreement is Industries, the rights of the holders of the Subordinated
Debentures under the Support Agreement effectively will be subordinate to all
obligations of Industries' subsidiaries other than Capital. See "Description
of the Subordinated Debentures--Subordination."
 
                                    CAPITAL
 
  Capital was incorporated in Indiana in 1989. Capital was organized by
Industries to engage in financing activities that provide funds for use in
Industries' business operations and those of its direct and indirect wholly-
owned subsidiaries, excluding Northern Indiana Public Service Company
("Northern Indiana"). Industries owns all of the 1,000 authorized capital
shares of Capital.
 
  Capital and Industries have entered into the Support Agreement, dated April
4, 1989, and amended as of May 15, 1989, December 10, 1990, and February 14,
1991, in which Industries has agreed, among other things, to ensure the timely
payment of principal, premium, if any, and interest owed on any debt
securities issued by Capital, with the limitation that no holder of such debt
securities will have recourse to or against the stock or assets of Northern
Indiana, or any interest of Industries or Capital therein. See "Description of
the Support Agreement."
 
  On March 27, 1991 the Commission issued an order pursuant to Section 6(c) of
the Investment Company Act of 1940, as amended (the "Investment Company Act"),
granting an exemption to Capital from all of the provisions of the Investment
Company Act, subject to Capital's compliance with the conditions set forth
therein.
 
  The principal executive offices of Capital are located at 5265 Hohman
Avenue, Hammond, Indiana 46320. Its telephone number is (219) 853-5200.

                                  INDUSTRIES
 
  Industries is an Indiana corporation, incorporated in 1987, which serves as
the holding company for a number of wholly-owned subsidiaries, including three
public utility operating companies: Northern Indiana, Kokomo Gas and Fuel
Company ("Kokomo Gas") and Northern Indiana Fuel and Light Company, Inc.
("NIFL"). In addition to Capital, Industries has two other major non-utility
subsidiaries, NIPSCO Development Company, Inc. and NIPSCO Energy Services,
Inc. The principal executive offices of Industries are located at 5265 Hohman
Avenue, Hammond, Indiana 46320, and its telephone number is (219) 853-5200.
 
  Northern Indiana, Industries' largest and dominant subsidiary, was
incorporated in Indiana in 1912 and supplies electricity and natural gas to
the public in 30 counties in the northern part of Indiana, serving an area of
about 12,000 square miles with a population of approximately 2,188,000. At
September 30, 1995, it supplied approximately 405,100 customers with
electricity and approximately 632,100 customers with natural gas. For the
twelve months ended September 30, 1995, about 63% of its revenues were derived
from the sale of electricity and about 37% from the sale and transportation of
natural gas. Kokomo Gas, which was incorporated in Indiana in 1917, and NIFL,
which was incorporated in Indiana in 1906, are both engaged in supplying
natural gas to the public in service territories contiguous to Northern
Indiana's service territory. At September 30, 1995, Kokomo Gas and NIFL served
approximately 31,400 and 30,400 customers, respectively.
 
                                USE OF PROCEEDS
 
  Capital will advance the net proceeds of this offering to Industries
promptly after completion of the offering. In the interim, Capital will invest
any funds held by it only in the manner permitted by Rule 3a-5 under the
Investment Company Act. Industries will use $35,000,000 of the funds received
to pay for the mandatory redemption of all of its outstanding 8.75% Cumulative
Preferred Shares on January 14, 1996 (or, if such funds are not received prior
to such redemption date, to repay short-term bank borrowings incurred to
redeem the 8.75% Cumulative Preferred Shares).
 
  Industries will use the balance of the funds received to repay earlier
advances made to Industries out of a portion of the proceeds of Capital's
short-term bank borrowings and commercial paper issuances, which Capital will
then repay. These bank and commercial paper borrowings had an average interest
rate of 6.02% per annum at September 30, 1995. The proceeds of these short-
term borrowings were used by Industries for general corporate purposes,
including the purchase of Industries' Common Shares pursuant to Industries'
share repurchase program.

                  DESCRIPTION OF THE SUBORDINATED DEBENTURES
 
  The Subordinated Debentures will be issued under an Indenture, dated as of
January   , 1996 (the "Indenture"), among Capital, Industries and Chemical
Bank, as trustee (the "Trustee"), which shall act as indenture trustee for the
purposes of the Trust Indenture Act of 1939, as amended. The forms of the
Indenture and the Subordinated Debentures are filed as exhibits to the
Registration Statement. Capitalized terms used in this section which are not
otherwise defined in this Prospectus shall have the meanings set forth in the
Indenture.
 
  The following summaries of certain provisions of the Subordinated Debentures
and the Indenture do not purport to be complete and are subject to, and are
qualified in their entirety by express reference to, all the provisions of the
Subordinated Debentures and the Indenture, including the definitions therein
of certain terms.
 
GENERAL
 
  The Subordinated Debentures will be unsecured, subordinated obligations of
Capital. The Subordinated Debentures are not subject to a sinking fund
provision. The entire principal amount of the Subordinated Debentures will
mature and become due and payable, together with any accrued and unpaid
interest thereon, on            , 2026.
 
  The Indenture does not limit the aggregate principal amount of Subordinated
Debentures that may be issued thereunder and provides that Subordinated
Debentures may be issued thereunder from time to time in one or more series.
The Subordinated Debentures are issuable in one or more series pursuant to an
indenture supplement to the Indenture or a resolution of the Company's Board
of Directors or a special committee thereof (each, a "Supplemental
Indenture").
 
  The Subordinated Debentures will initially be issued as a Global Security
(as defined below). As described herein, under certain limited circumstances,
Subordinated Debentures may be issued in certificated form in exchange for a
Global Security. See "Global Securities" below. In the event that Subordinated
Debentures are issued in certificated form, such Subordinated Debentures will
be in denominations of $1,000 or any integral multiple thereof and may be
transferred or exchanged at the offices described below. No service charge
will be made for any transfer or exchange of Subordinated Debentures, but
Capital may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith.
 
  Payments on Subordinated Debentures issued as a Global Security will be made
to DTC, a successor depositary or, in the event that no depositary is used, to
a Paying Agent for the Subordinated Debentures. In the event the Subordinated
Debentures are issued in certificated form, principal, premium, if any, and
interest will be payable, the transfer of the Subordinated Debentures will be
registrable and Subordinated Debentures will be exchangeable for Subordinated
Debentures of other denominations of a like aggregate principal amount at the
corporate trust office of the Trustee in New York, New York; provided that
payment of interest may be made at the option of Capital by check mailed to
the address of the persons entitled thereto as they appear in the Security
Register.
 
  The Indenture does not contain any provisions that may afford the Holders of
Subordinated Debentures protection in the event of a highly leveraged
transaction or other transaction involving Capital or Industries that may
occur in connection with a takeover attempt resulting in a decline in the
credit rating of the Subordinated Debentures. The Indenture also does not
contain any provisions that would limit the ability of Capital or Industries
to incur indebtedness.
 
SUBORDINATION
 
  The Indenture provides that the Subordinated Debentures are subordinated and
junior in right of payment to all Senior Indebtedness of Capital. No payment
of principal of, or premium, if any, or interest on the
 
                                       8
<PAGE>
 
Subordinated Debentures may be made (i) if any Senior Indebtedness of Capital
is not paid when due, (ii) if any applicable grace period with respect to such
default has ended and such default has not been cured or waived or ceased to
exist, or (iii) if the maturity of any Senior Indebtedness of Capital has been
accelerated because of a default and such acceleration has not been revoked in
accordance with the instrument evidencing such Senior Indebtedness or such
Senior Indebtedness has not been paid in full. Upon any distribution of assets
of Capital to creditors upon any dissolution, winding-up, liquidation or
reorganization, whether voluntary or involuntary, or in bankruptcy, insolvency,
receivership or other proceedings, all principal, premium, if any, and interest
due or to become due on all Senior Indebtedness of Capital must be paid in full
before the holders of Subordinated Debentures are entitled to receive or retain
any payment. Upon satisfaction of all claims of all Senior Indebtedness then
outstanding, the rights of the holders of the Subordinated Debentures will be
subrogated to the rights of the holders of Senior Indebtedness of Capital to
receive payments or distributions applicable to Senior Indebtedness until all
amounts owing on the Subordinated Debentures are paid in full.
 
  "Senior Indebtedness" means the principal of, and premium, if any, and
interest on and any other payment due pursuant to any of the following, whether
outstanding at the date of execution of the Indenture or thereafter incurred,
created or assumed: (i) all indebtedness of Capital evidenced by notes,
debentures, bonds or other securities sold by Capital for money, (ii) all
indebtedness of others of the kinds described in the preceding clause (i)
assumed by or guaranteed in any manner by Capital or in effect guaranteed by
Capital through an agreement to purchase, contingent or otherwise, and (iii)
all renewals, extensions or refundings of indebtedness of the kinds described
in either of the preceding clauses (i) and (ii) unless, in the case of any
particular indebtedness, renewal, extension or refunding, the instrument
creating or evidencing the same or the assumption or guarantee of the same
expressly provides that such indebtedness, renewal, extension or refunding is
not superior in right of payment to or is pari passu with the Subordinated
Debentures. Such Senior Indebtedness will continue to be Senior Indebtedness
and entitled to the benefits of the subordination provisions set forth in
Article Fourteen of the Indenture irrespective of any amendment, modification
or waiver of any term of such Senior Indebtedness.
 
  The Indenture does not limit the aggregate amount of Senior Indebtedness that
may be issued by Capital. As of September 30, 1995, Senior Indebtedness of
Capital aggregated approximately $69.2 million. The Indenture does not contain
any cross-defaults to any other indebtedness of Capital or Industries and,
therefore, a default with respect to, or the acceleration of, any such other
indebtedness will not constitute an Event of Default with respect to the
Subordinated Debentures. Because the obligor under the Support Agreement is
Industries, the rights of the holders of the Subordinated Debentures under the
Support Agreement effectively will be subordinate to all obligations of
Industries' subsidiaries other than Capital.
 
OPTIONAL REDEMPTION
 
  Capital shall have the right to redeem the Subordinated Debentures, in whole
or in part, from time to time, on or after           , 2006, upon not less than
30 nor more than 60 days notice, at a redemption price equal to the percentage
of the principal amount set forth below if redeemed during the 12 month period
beginning            of the years indicated:

and thereafter at 100% of the principal amount thereof, in each case together
with accrued and unpaid interest, if any, to the redemption date. If less than
all of the Subordinated Debentures are to be redeemed, the particular
Subordinated Debentures to be redeemed will be selected by the Trustee, not
more than 60 days prior to the redemption date, as the Trustee shall deem fair
and appropriate.
 
                                       9
<PAGE>
 
INTEREST
 
  Each Subordinated Debenture shall bear interest at the rate per annum shown
on the front cover of this Prospectus from the original date of issuance until
the principal becomes due and payable. Such interest shall be payable
quarterly in arrears on March 31, June 30, September 30 and December 31 of
each year (each, an "Interest Payment Date"), commencing March 31, 1996, to
the person in whose name such Subordinated Debenture is registered, at the
close of business on the Business Day next preceding such Interest Payment
Date.
 
  The amount of interest payable for any period will be computed on the basis
of a 360-day year of twelve 30-day months. The amount of interest payable for
any period shorter than a full quarterly period for which interest is computed
will be computed on the basis of the actual number of days elapsed per 30-day
month. In the event that any date on which interest is payable on the
Subordinated Debentures is not a Business Day, then payment of the interest
payable on such date will be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of any such
delay), except that, if such Business Day is in the next succeeding calendar
year, then such payment shall be made on the immediately preceding Business
Day, in each case with the same force and effect as if made on such date.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD
 
  Capital shall have the right at any time, and from time to time, during the
term of the Subordinated Debentures, so long as an Event of Default has not
occurred and is not continuing, to defer payments of interest by extending the
interest payment period for a period not exceeding 20 consecutive quarters
(the "Extension Period"), at the end of which Extension Period Capital shall
pay all interest then accrued and unpaid together with interest thereon
compounded quarterly at the rate specified for the Subordinated Debentures to
the extent permitted by applicable law. Capital shall give the Trustee and the
holders of the Subordinated Debentures notice of its selection of any
Extension Period 10 Business Days prior to the earlier of (i) the next
Interest Payment Date or (ii) the date upon which Capital is required to give
notice to the holders of the Subordinated Debentures (or, if applicable, to
the New York Stock Exchange or other applicable self-regulatory organization)
of the record or payment date of such related interest payment. During any
such Extension Period, Capital shall not (i) declare or pay any dividends on,
make any distribution with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock, (ii) make any
payment of interest, principal or premium, if any, on or repay, repurchase or
redeem any debt securities issued by Capital that rank pari passu with or
junior to the Subordinated Debentures or (iii) make any guarantee payments
with respect to any of the foregoing.
 
  Prior to the termination of any such Extension Period, Capital may further
defer payments of interest by extending the interest payment period; provided,
however, that, such Extension Period, including all such previous and further
extensions, may not exceed 20 consecutive quarters. Upon the termination of
any Extension Period and the payment of all amounts then due, Capital may
commence a new Extension Period, subject to the terms set forth in this
section. No interest during an Extension Period, except at the end thereof,
shall be due and payable other than with respect to a Subordinated Debenture
redeemed by Capital during such Extension Period. Capital has no present
intention of exercising its right to defer payments of interest by extending
the interest payment period on the Subordinated Debentures.
 
GLOBAL SECURITIES
 
  The Subordinated Debentures will be issued in the form of one or more Global
Securities, which will have an aggregate principal amount equal to that of the
Subordinated Debentures. The Global Security or Securities will be deposited
with, or on behalf of, DTC and registered in the name of DTC or its nominee.
 
  DTC has advised Capital, Industries and the Underwriters that DTC is (i) a
limited-purpose trust company organized under the New York Banking Law, (ii) a
"banking organization" within the meaning of the New York Banking Law, (iii) a
member of the Federal Reserve System, (iv) a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and (v) a "clearing agency"
registered pursuant to the provisions
 
                                      10
<PAGE>
 
of Section 17A of the Exchange Act. DTC was created to hold securities of its
participating organizations ("participants") and to facilitate the clearance
and settlement among its participants of securities transactions, such as
transfers and pledges, in such securities through electronic computerized
book-entry changes in participants' accounts, thereby eliminating the need for
physical movement of securities certificates. Participants include securities
brokers and dealers (including the Underwriters), banks, trust companies,
clearing corporations and certain other organizations, some of whom (and/or
their representatives) own DTC. Access to DTC's book-entry system is also
available to others, such as banks, brokers, dealers and trust companies that
clear transactions through or maintain a custodial relationship with a
participant, either directly or indirectly. Persons who are not participants
may beneficially own securities held by DTC only through participants.
 
  As long as DTC, or its nominee, is the registered owner of the Global
Security or Securities representing the Subordinated Debentures, DTC or such
nominee, as the case may be, will be considered the sole owner and holder of
such Global Security and the Subordinated Debentures represented thereby for
all purposes under the Indenture. Owners of beneficial interests in such
Global Security will not be entitled to have such Global Security or, except
in limited circumstances, the Subordinated Debentures represented thereby
registered in their names, will not receive or be entitled to receive physical
delivery of Subordinated Debentures in certificated form and will not be
considered the holders thereof for any purposes under the Indenture. All
payments of principal of and interest on a Global Security will be made to DTC
or its nominee, as the case may be, as the holder thereof. The laws of some
jurisdictions require that certain purchasers of securities take physical
delivery of such securities in certificated form. The foregoing limitations
and such laws may impair the ability to transfer beneficial interests in such
Global Securities.
 
  In connection with the issuance of the Global Security or Securities
representing the Subordinated Debentures, DTC will credit on its book-entry
registration and transfer system the respective principal amounts of the
Subordinated Debentures represented by such Global Securities to the accounts
of its participants. Ownership of beneficial interests in a Global Security
will be shown only on, and the transfer of those ownership interests will be
effected only through, records maintained by DTC (with respect to
participants' interests) or any such participant (with respect to interests of
persons held by such participants on their behalf). Payments, transfers,
exchanges and other matters relating to beneficial interests in a Global
Security may be subject to various policies and procedures adopted by DTC from
time to time. None of Capital, Industries or the Trustee, or any agent of any
of the foregoing, will have any responsibility or liability for any aspect of
DTC's or any participant's records relating to, or for payments made on
account of, beneficial ownership interests in a Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial
interests.
 
  DTC may discontinue providing its services as securities depositary with
respect to the Subordinated Debentures at any time by giving reasonable notice
to Capital. Under such circumstances, in the event that a successor securities
depositary is not obtained, Subordinated Debentures in certificated form are
required to be printed and delivered.
 
DISCONTINUANCE OF THE DEPOSITARY'S SERVICES
 
  A Global Security shall be exchangeable for Subordinated Debentures
registered in the names of persons other than the depositary or its nominee
only if (i) the depositary notifies Capital that it is unwilling or unable to
continue as a depositary for such Global Security and no successor depositary
shall have been appointed, (ii) the depositary, at any time, ceases to be a
clearing agency registered under the Exchange Act at which time the depositary
is required to be so registered to act as such depositary and no successor
depositary shall have been appointed, (iii) Capital, in its sole discretion,
determines that such Global Security shall be so exchangeable or (iv) there
shall have occurred an Event of Default with respect to such Subordinated
Debentures. Any Global Security that is exchangeable pursuant to the preceding
sentence shall be exchangeable for Subordinated Debentures registered in such
names as the depositary shall direct. It is expected that such instructions
will be based upon directions received by the depositary from its participants
with respect to ownership of beneficial interests in such Global Security.

<PAGE>
 
CONSOLIDATION, MERGER AND SALE
 
  Under the terms of the Indenture, neither Capital nor Industries may merge
or consolidate with or into any other Corporation, or sell or convey
substantially all of its assets or otherwise engage in restructuring
transactions unless (i) the Corporation formed by any such consolidation or
into which it is merged or the Person which acquires by conveyance or
transfer, or which leases, its properties and assets substantially as an
entirety shall be a Corporation organized and existing under the laws of any
domestic jurisdiction and shall expressly assume, in the case of Capital, its
obligations under the Subordinated Debentures and the Indenture and, in the
case of Industries, its obligations under the Indenture and the Support
Agreement, (ii) immediately after giving effect to such transaction, no Event
of Default, and no event which, after notice or lapse of time, would become an
Event of Default, shall have occurred and be continuing, and (iii) Capital or
Industries, as applicable, shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that such consolidation,
merger, conveyance, transfer or lease complies with the Indenture and that all
conditions precedent therein provided for relating to such transaction have
been complied with.
 
EVENTS OF DEFAULT
 
  The Indenture provides that any one or more of the following events that has
occurred and is continuing shall constitute an Event of Default with respect
to the Subordinated Debentures: (i) default in the payment of any interest
upon any Subordinated Debenture when the same becomes due and payable and
continues for 30 days; provided, however, that a valid extension of the
interest payment period by Capital for the Subordinated Debentures shall not
constitute a default in the payment of interest for this purpose; (ii) default
in the payment of principal of any Subordinated Debenture when due; (iii)
default in the performance or breach of any covenant or warranty of Capital or
Industries in the Indenture or the Support Agreement (other than a covenant or
warranty included in or pursuant to the Indenture solely for the benefit of
one or more series of debt securities other than the Subordinated Debentures),
and continuance thereof for 30 days after written notice to Capital and
Industries as provided in the Indenture; and (iv) certain events in
bankruptcy, insolvency or reorganization of Capital, Industries or Northern
Indiana.
 
  If an Event of Default with respect to the Subordinated Debentures occurs
and is continuing, either the Trustee or the Holders of at least 33 percent in
principal amount of the outstanding Subordinated Debentures may declare all
such Subordinated Debentures due and payable immediately. At any time after
the declaration of acceleration with respect to the Subordinated Debentures
has been made, but before a judgment or decree based on acceleration has been
obtained, the Holders of a majority in principal amount of the outstanding
Subordinated Debentures may, under certain circumstances, rescind and annul
such acceleration.
 
  The Indenture provides that, subject to the duty of the Trustee during
default to act with the required standard of care, the Trustee will be under
no obligation to exercise any of its rights or powers under the Indenture at
the request or direction of any of the Holders, unless such Holders shall have
offered to the Trustee reasonable indemnity. Subject to such provisions for
the indemnification of the Trustee, the Holders of a majority in principal
amount of the outstanding Subordinated Debentures will have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred on the
Trustee, with respect to the Subordinated Debentures. The right of a Holder of
any Subordinated Debenture to institute a proceeding with respect to the
Indenture is subject to certain conditions precedent, but each Holder has an
absolute and unconditional right to receive payment of principal when due and
to institute suit for the enforcement of any such payment. The Indenture
provides that the Trustee, within 90 days after the occurrence of a default
with respect to the Subordinated Debentures, is required to give the Holders
of the Subordinated Debentures notice of such default, unless cured or waived;
provided that, except in the case of default in the payment of principal on
any Subordinated Debenture, the Trustee may withhold such notice if it
determines in good faith that it is in the interest of such Holders to do so.
 
  Each of Capital and Industries will be required to furnish annually to the
Trustee a statement as to the performance by it of certain of its obligations
under the Indenture and as to any default in such performance.
 
 
                                      12
<PAGE>
 
  The Holders of not less than a majority in principal amount of the
Subordinated Debentures may, on behalf of the Holders of all the Subordinated
Debentures, waive any past default under the Indenture with respect to the
Subordinated Debentures and its consequences, except a default (i) in the
payment of the principal of or interest on any Subordinated Debenture or (ii)
in respect of a covenant or provision that cannot be modified or amended
without the consent of the Holder of each outstanding Subordinated Debenture
affected thereby.
 
MODIFICATION OF THE INDENTURE
 
  The Indenture contains provisions permitting Capital, Industries and the
Trustee to execute supplemental indentures, with the consent of the holders of
not less than a majority in principal amount of the outstanding securities of
each series then outstanding under the Indenture affected by such supplemental
indenture, adding any provisions to or changing in any manner or eliminating
any of the provisions of the Indenture or modifying in any manner the rights
of the holders of securities of each such series, except that no such
supplemental indenture, without the consent of the holders of all such
securities so affected, may, among other things, (i) change the stated
maturity of any securities outstanding under the Indenture, or reduce the
principal amount thereof or the rate of interest thereon or any premium
payable upon the redemption thereof, or change the method of calculating the
rate of interest thereon, or reduce the amount of principal of the securities
due at maturity or upon a declaration of acceleration of maturity thereof
pursuant to the Indenture, or (ii) reduce the aforesaid percentage of
securities of any series outstanding under the Indenture, the holders of which
are required to consent to any such supplemental indenture. See also
"Description of the Support Agreement."
 
  The Indenture also permits Capital, Industries and the Trustee to amend the
Indenture in certain circumstances without the consent of the holders of the
securities then outstanding under the Indenture to evidence the merger of
Industries or Capital or the replacement of the Trustee with respect to the
securities of one or more series and for certain other purposes.
 
                     DESCRIPTION OF THE SUPPORT AGREEMENT
 
  The Support Agreement between Capital and Industries provides that, during
the term thereof, (i) Industries will own all of the voting stock of Capital,
(ii) Industries will cause Capital to have at all times a positive net worth
(net assets less intangible assets, if any), as determined in accordance with
generally accepted accounting principles, and (iii) if Capital is unable to
make timely payment of principal of or any premium or interest on any Debt (as
defined below) issued by Capital, Industries will, at the request of Capital
or any Lender (as defined below), provide funds to Capital to make such
payments. The Support Agreement also provides that any Lender to Capital shall
have the right to demand that Capital enforce its rights against Industries
under the Support Agreement as described in the previous sentence, and, in the
event that Capital fails to require Industries to perform such obligations or
Capital defaults in the timely payment of principal of or any premium or
interest on any Debt owed to a Lender, such Lender may proceed directly
against Industries to enforce Capital's rights against Industries under the
Support Agreement or to obtain payment of such defaulted principal, premium or
interest owed to such Lender.
 
  The Support Agreement provides that in no event may any Lender, on default
of Capital or Industries or upon failure by Capital or Industries to comply
with the Support Agreement, have recourse to or against the stock or assets of
Northern Indiana, or any interest of Capital or Industries therein.
Notwithstanding this limitation, the Support Agreement provides that funds
available to Industries to satisfy any obligations under the Support Agreement
will include cash dividends paid by Northern Indiana to Industries. In
addition to the cash dividends paid to Industries by any of its subsidiaries,
the assets of Industries other than the stock and assets of Northern Indiana
are available as recourse to holders of Capital's Debt. The carrying value of
such assets reflected in Industries' consolidated balance sheet at September
30, 1995 is approximately $345.6 million. The term "Debt" is defined in the
Support Agreement as debt securities or other obligations, and includes the
Subordinated Debentures. The term "Lender" is defined in the Support Agreement
as any person, firm or corporation to which Capital is indebted for money
borrowed or to which Capital otherwise owes any Debt or
 
                                      13
<PAGE>
 
which is acting as trustee or authorized representative on behalf of such
person, firm or corporation. The Indenture provides that each Holder of a
Subordinated Debenture, as well as the Trustee, shall be considered a "Lender"
for purposes of the Support Agreement.
 
  Funds to pay the principal of, and premium, if any, and interest on, the
Subordinated Debentures pursuant to the Support Agreement would come from
earnings in the form of dividends paid to Industries by Northern Indiana,
Kokomo Gas and NIFL, the earnings of other businesses of Industries and its
subsidiaries or the proceeds of refinancing transactions. During the next few
years, it is expected that the majority of Industries' earnings that would
ultimately be available to pay the principal of, and premium, if any, and
interest on, the Subordinated Debentures will depend upon dividends paid to
Industries by Northern Indiana. Northern Indiana's Indenture of Mortgage
provides that Northern Indiana will not declare or pay any dividends on any
class of capital stock (other than preferred or preference stock) except out
of earned surplus or net profits of Northern Indiana. At September 30, 1995,
Northern Indiana had approximately $139.5 million of retained earnings (earned
surplus) available for the payment of dividends. Future dividends payable by
Northern Indiana to Industries will depend upon adequate retained earnings,
adequate future earnings and the absence of adverse developments. In addition,
since Industries is a holding company, the right of its creditors, including
holders of the Subordinated Debentures pursuant to the Support Agreement, to
participate in any distribution of the assets of any subsidiary other than
Capital upon its liquidation or reorganization or otherwise is necessarily
subject to the prior claims of creditors of the subsidiary, except to the
extent claims of Industries as a creditor may be recognized. The Indenture
does not limit the amount of indebtedness that Capital, Industries or any of
Industries' other subsidiaries may incur.
 
  The Support Agreement may be amended or terminated at any time by agreement
of Industries and Capital, provided that (i) no amendment regarding the terms
described above may be made unless all Lenders consent in advance and in
writing to such amendment; (ii) no amendment regarding any other term of the
Support Agreement may be made in a manner that adversely affects the rights of
Lenders unless all affected Lenders consent in advance and in writing to such
amendment; and (iii) no termination shall be effective until such time as all
Debt (including the Subordinated Debentures) shall have been paid in full.
 
                       UNITED STATES TAX CONSIDERATIONS
 
GENERAL
 
  The following is a summary of certain of the material United States federal
income tax consequences of the purchase, ownership and disposition of
Subordinated Debentures and represents the opinion of Schiff Hardin & Waite,
counsel to Capital and Industries, insofar as it relates to matters of law and
legal conclusions. Unless otherwise stated, this summary deals only with
Subordinated Debentures held as capital assets by holders who purchase the
Subordinated Debentures upon original issuance ("Initial Holders"). It does
not deal with special classes of holders such as banks, thrifts, real estate
investment trusts, regulated investment companies, insurance companies,
dealers in securities or currencies, tax-exempt investors, or persons that
will hold the Subordinated Debentures as a position in a "straddle," as part
of a "synthetic security" or "hedge," as part of a "conversion transaction" or
other integrated investment, or as other than a capital asset. This summary
also does not address the tax consequences to persons whose functional
currency is other than the U.S. Dollar or the tax consequences to
shareholders, partners or beneficiaries of a holder of Subordinated
Debentures. Further, it does not include any description of any alternative
minimum tax consequences or the tax laws of any state or local government or
of any foreign government that may be applicable to the Subordinated
Debentures. This summary is based on the Internal Revenue Code of 1986, as
amended (the "Code"), Treasury regulations thereunder and administrative and
judicial interpretations thereof, as of the date hereof, all of which are
subject to change, possibly on a retroactive basis.
 
ORIGINAL ISSUE DISCOUNT
 
  Because Capital has the option, under the terms of the Subordinated
Debentures, to defer payments of interest by extending interest payment
periods for up to 20 quarters, all payments in respect of the Subordinated
Debentures will be treated as "original issue discount" ("OID"). Holders of
debt instruments issued with OID
 
                                      14
<PAGE>
 
must include that discount in income on an economic accrual basis whether or
not cash attributable to the interest has yet been received, regardless of
their method of tax accounting. Generally, all of a holder's taxable interest
income with respect to the Subordinated Debentures will be accounted for as
OID, and actual distributions of stated interest will not be separately
reported as taxable income. The amount of OID that accrues in any month will
approximately equal the amount of the interest that accrues on the
Subordinated Debentures in that month at the stated interest rate. In the
event that the interest payment period is extended, holders will continue to
accrue OID approximately equal to the amount of the interest payment due at
the end of the Extension Period on an economic accrual basis over the length
of the extended interest period.
 
MARKET DISCOUNT AND BOND PREMIUM
 
  Holders of Subordinated Debentures other than Initial Holders may be
considered to have acquired their Subordinated Debentures with market discount
or acquisition premium as such phrases are defined for United States federal
income tax purposes. Such holders are advised to consult their tax advisors as
to the income tax consequences of the acquisition, ownership and disposition
of the Subordinated Debentures.
 
SALES OF SUBORDINATED DEBENTURES
 
  A holder that sells Subordinated Debentures will recognize gain or loss
equal to the difference between its adjusted tax basis in the Subordinated
Debentures and the amount realized on the sale of such Subordinated
Debentures. A holder's adjusted tax basis in the Subordinated Debentures
generally will be its initial purchase price increased by OID previously
includible in such holder's gross income to the date of disposition and
decreased by payments received on the Subordinated Debentures. Such gain or
loss generally will be a capital gain or loss and generally will be a long-
term capital gain or loss if the Subordinated Debentures have been held for
more than one year.
 
  The Subordinated Debentures may trade at a price that does not accurately
reflect the value of accrued but unpaid interest thereon. A holder who
disposes of his Subordinated Debentures between record dates for payments of
interest thereon will be required to include accrued but unpaid interest on
the Subordinated Debentures through the date of disposition in income as
ordinary income, and to add such amount to his adjusted tax basis in the
Subordinated Debentures disposed of. To the extent the selling price is less
than the holder's adjusted tax basis (which will include, in the form of OID,
all accrued but unpaid interest) a holder will recognize a capital loss.
Subject to certain limited exceptions, capital losses cannot be applied to
offset ordinary income for United States federal income tax purposes.
 
UNITED STATES ALIEN HOLDERS
 
  For purposes of this discussion, a "United States Alien Holder" is any
corporation, individual, partnership, estate or trust that is, as to the
United States, a foreign corporation, a non-resident alien individual, a
foreign partnership, or a non-resident fiduciary of a foreign estate or trust.
 
  Under present United States federal income tax law: (i) payments by Capital
or Industries to any holder of a Subordinated Debenture that is a United
States Alien Holder will not be subject to United States federal withholding
tax; provided that (a) the beneficial owner of the Subordinated Debenture does
not actually or constructively own 10% or more of the total combined voting
power of all classes of stock of Industries entitled to vote, (b) the
beneficial owner of the Subordinated Debenture is not a controlled foreign
corporation that is related to Industries through stock ownership, and (c)
either (A) the beneficial owner of the Subordinated Debenture certifies to
Capital or its agent, under penalties of perjury, that it is not a United
States holder and provides its name and address or (B) a securities clearing
organization, bank or other financial institution that holds customers'
securities in the ordinary course of its trade or business (a "Financial
Institution"), and holds the Subordinated Debenture in such capacity,
certifies to Capital or its agent, under penalties of perjury, that such
statement has been received from the beneficial owner by it or by a Financial
Institution between it and the beneficial owner and furnishes Capital or its
agent with a copy thereof; and (ii) a United States Alien Holder of
 
                                      15
<PAGE>
 
a Subordinated Debenture will generally not be subject to United States
federal income or withholding tax on any gain realized upon the sale or other
disposition of a Subordinated Debenture, except that a United States Alien
Holder will be subject to United States income tax on any gain if such United
States Alien Holder (a) is engaged in a trade or business in the United States
and such gain is effectively connected to the conduct of such trade or
business or (b) is an individual present in the United States for 183 days or
more during the taxable year, and certain other conditions are met.
 
INFORMATION REPORTING TO HOLDERS
 
  Subject to the qualifications discussed below, income on the Subordinated
Debentures will be reported to holders on Forms 1099, which forms should be
mailed to holders of Subordinated Debentures by January 31 following each
calendar year. Capital will be obligated to report annually to Cede & Co., as
holder of record of the Subordinated Debentures, the OID related to the
Subordinated Debentures that accrued during the year. Capital currently
intends to report such information on Form 1099 prior to January 31 following
each calendar year. The Underwriters have indicated to Capital that, to the
extent that they hold Subordinated Debentures as nominees for beneficial
holders, they currently expect to report to such beneficial holders on Forms
1099 by January 31 following each calendar year. Under current law, holders of
Subordinated Debentures who hold as nominees for beneficial holders will not
have any obligation to report information regarding the beneficial holders to
Capital. Capital, moreover, will not have any obligation to report to
beneficial holders who are not also record holders. Thus, beneficial holders
of Subordinated Debentures who hold their Subordinated Debentures through the
Underwriters will receive Forms 1099 reflecting the income on their
Subordinated Debentures from such nominee holders rather than Capital.
 
BACKUP WITHHOLDING
 
  Payments made in respect of, and proceeds from the sale of, the Subordinated
Debentures may be subject to a "backup" withholding tax of 31% unless the
holder complies with certain identification requirements. Any withheld amounts
will be allowed as a credit against the holder's United States federal income
tax, provided the required information is provided to the Internal Revenue
Service.
 
  THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED
FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A
HOLDER'S PARTICULAR SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH
RESPECT TO THE TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND
DISPOSITION OF THE SUBORDINATED DEBENTURES, INCLUDING THE TAX CONSEQUENCES
UNDER STATE, LOCAL, FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF
CHANGES IN UNITED STATES FEDERAL OR OTHER TAX LAWS.

</TABLE>
 
  The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the Subordinated Debentures are
subject to the approval of certain legal matters by their counsel and to
certain other conditions. The Underwriters are committed to take and pay for
all of the Subordinated Debentures if any are taken.
 
  The Underwriters initially propose to offer all or part of the Subordinated
Debentures directly to the public at the public offering price set forth on
the cover page hereof this Prospectus, and all or part to certain dealers at a
price that represents a concession not in excess of    % of the principal
amount of the Subordinated Debentures. Any Underwriter may allow, and such
dealers may reallow, a concession not in excess of    % of the principal
amount of the Subordinated Debentures to certain other dealers. After the
initial public offering, the public offering price and concession and discount
to dealers may be changed by the Underwriters.
 
  The Subordinated Debentures are a new issue of securities with no
established trading market. The Representatives have advised Capital that they
intend to make a market in the Subordinated Debentures. The Representatives
will have no obligation to make a market in the Subordinated Debentures,
however, and may cease market making activities, if commenced, at any time.
Accordingly, no assurance can be given as to the liquidity of the trading
market for the Subordinated Debentures.
 
  Capital and Industries have agreed to indemnify the Underwriters against
certain liabilities, including liabilities under the Securities Act.
 
  Certain of the Underwriters and dealers and their associates may be engaged
in transactions with and perform services for Capital and Industries and their
affiliates in the ordinary course of business.
 
                                 LEGAL MATTERS

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The By-Laws of Industries provide for indemnification by Industries of each
director and officer of Industries and Capital to the fullest extent permitted
by law for liability of such director or officer arising by reason of his or
her status as a director or officer of Industries or Capital. Under the By-
Laws of Industries as well as the Indiana Business Corporation Law (the
"Indiana BCL"), Industries is required to indemnify the directors and officers
of Industries and Capital against expenses, judgments, decrees, fines,
penalties and settlements actually and reasonably incurred by such person in
connection with any action, suit or proceeding, whether civil, criminal,
administrative or investigative, to which such person is a party by reason of
his or her connection with Industries and Capital, provided that such person
acted in good faith and in a manner he or she reasonably believed to be in the
best interest of Industries and Capital, or, with respect to a criminal
proceeding, has no reasonable cause to believe that his or her conduct was
unlawful.
 
  The By-Laws of Industries provide that except where a director or officer is
substantially and finally successful on the merits, Industries may not
indemnify a director or officer (unless ordered by a court) until after a
determination has been made that indemnification of the director or officer is
permissible because he or she met the applicable standards of conduct.
Industries also may not advance expenses prior to the disposition of an
action, suit or proceeding until: (a) the director or officer provides
Industries with a written affirmation of his or her good faith belief that he
or she has met the applicable standards of conduct and an undertaking to repay
the advance if it is ultimately determined that he or she did not meet the
applicable standards of conduct, and (b) a determination has been made, that,
based on the facts then known to those making the determination, the director
or officer met the applicable standards of conduct. The determination that a
director or officer has met the applicable standards of conduct may be made by
a majority vote of a quorum consisting of disinterested directors, a majority
vote of a committee designated by the board of directors consisting of two or
more disinterested directors (only if a quorum of the board cannot be
obtained), special legal counsel or a majority vote of disinterested
shareholders.
 
  As authorized under the By-Laws of Industries and the Indiana BCL,
Industries and its subsidiaries, including Capital, have insurance which
insures directors and officers for acts committed as such directors or
officers which are determined not to be indemnifiable under Industries'
indemnity provisions.
 
  Section 8 of the Underwriting Agreement filed as Exhibit 1 to this
Registration Statement provides for the Underwriters to indemnify Capital and
Industries and their respective officers and directors and each person, if
 
                                     II-1
<PAGE>
 
any, who controls Capital or Industries within the meaning of the Securities
Act, against certain liabilities in connection with the offering described
herein, including liabilities under the federal securities laws, under certain
circumstances.
 
ITEM 16. LIST OF EXHIBITS.
 
  The exhibits filed herewith are set forth on the Exhibit Index included as
part of this Registration Statement.
 
ITEM 17. UNDERTAKINGS.
 
  (a) The undersigned registrants hereby undertake that, for purposes of
determining any liability under the Securities Act of 1933, each filing of
Industries' annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to Section 15(d) of the Securities
Exchange Act of 1934) that is incorporated by reference in the Registration
Statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
 
  (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933, may be permitted to directors, officers and controlling persons
of either registrant pursuant to the foregoing provisions, or otherwise, each
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by either
registrant of expenses incurred or paid by a director, officer or controlling
person of either registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, each registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.
 
  (c) The undersigned registrants hereby undertake that:
 
    (1) 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 registrants pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) 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.

Dear Sirs:

     NIPSCO Capital Markets, Inc., an Indiana corporation (the "Company") and a
wholly-owned subsidiary of NIPSCO Industries, Inc., an Indiana corporation
("Industries"), proposes, subject to the terms and conditions stated herein, to
issue and sell to the several Underwriters named in Schedule I hereto (the
"Underwriters"), an aggregate of $75,000,000 principal amount of the _____%
Quarterly Debt Capital Securities of the Company (Junior Subordinated Deferrable
Interest Debentures, Series A) specified above (the "Securities") in the
respective principal amounts designated in Schedule I hereto.

     1.  The Company and Industries jointly and severally represent and warrant
to, and agree with, each of the several Underwriters that:

     (a) A registration statement on Form S-3 in respect of the Securities has
     been filed with the Securities and Exchange Commission (the "Commission");
     such registration statement in the form heretofore delivered to you has
     been declared effective by the Commission; no other document with respect
     to such registration statement or document incorporated by reference
     therein has heretofore been filed with the Commission; and no stop order
     suspending the effectiveness of such registration statement has been issued
     and no proceeding for that purpose has been initiated or threatened by the
     Commission (any preliminary prospectus included in such registration
     statement or filed with the Commission pursuant to Rule 424(a) of the rules
     and regulations of the Commission under the Securities Act of 1933, as
     amended (the "Act"),  being hereinafter called a "Preliminary
<PAGE>
 
     Prospectus"; the various parts of such registration statement, including
     all exhibits thereto but excluding Form T-1 and including (i) the
     information contained in the form of final prospectus filed with the
     Commission pursuant to Rule 424(b) under the Act in accordance with Section
     5(a) hereof and deemed by virtue of Rule 430A under the Act to be part of
     the registration statement at the time it was declared effective and (ii)
     the documents incorporated by reference in the prospectus contained in the
     registration statement at the time such part of the registration statement
     became effective, each as amended at the time such part of the registration
     statement became effective, being hereinafter called the "Registration
     Statement"; such final prospectus, in the form first filed pursuant to Rule
     424(b) under the Act, being hereinafter called the "Prospectus"; any
     reference herein to any Preliminary Prospectus or 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 Preliminary Prospectus or Prospectus, as the case may be; any
     reference to any amendment or supplement to any Preliminary Prospectus or
     the Prospectus shall be deemed to refer to and include any documents filed
     after the time of filing of such Preliminary Prospectus or Prospectus, as
     the case may be, under the Securities Exchange Act of 1934, as amended (the
     "Exchange Act"), and incorporated by reference in such Preliminary
     Prospectus or Prospectus, as the case may be; and any reference to any
     amendment to the Registration Statement shall be deemed to refer to and
     include any annual report of Industries filed pursuant to Section 13(a) or
     15(d) of the Exchange Act after the effective date of the Registration
     Statement that is incorporated by reference in the Registration Statement);

          (b) No order preventing or suspending the use of any Preliminary
     Prospectus has been issued by the Commission, and each Preliminary
     Prospectus, at the time of filing thereof, conformed in all material
     respects to the requirements of the Act and the Trust Indenture Act of
     1939, as amended (the "Trust Indenture Act"), and the rules and regulations
     of the Commission thereunder, and did not contain an untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; provided,
     however, that this representation and warranty shall not apply to any
     statements or omissions made in reliance upon and in conformity with
     information furnished in writing to Industries or the Company by any
     Underwriter through you expressly for use therein;

                                      -2-
<PAGE>
 
          (c) The documents incorporated by reference in the Prospectus, when
     they became effective or were filed with the Commission, as the case may
     be, conformed in all material respects to the requirements of the Act or
     the Exchange Act, as applicable, and the rules and regulations of the
     Commission thereunder, and none of such documents 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; and any further documents so filed and incorporated by
     reference in the Prospectus, or any further amendment or supplement
     thereto, when such documents become effective or are filed with the
     Commission, as the case may be, will conform in all material respects to
     the requirements of the Act or the Exchange Act, as applicable, and the
     rules and regulations of the Commission thereunder and will not contain an
     untrue statement of a material fact or omit to state a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading; provided, however, that this representation and warranty
     shall not apply to any statements or omissions made in reliance upon and in
     conformity with information furnished in writing to Industries or the
     Company by any Underwriter through you expressly for use therein;

     (d) Giving effect to the interpretations of the requirements of the Act
     reflected in the Company's letter requesting "no-action" submitted to the
     staff of the Commission (the "Staff"), dated April 27, 1992, as
     supplemented by letters dated July 9, 1992 and September 21, 1992 (the "No-
     Action Request") and the Staff's response thereto dated September 25, 1992
     (the "Staff Response"), the Registration Statement conforms, and the
     Prospectus and any further amendments or supplements to the Registration
     Statement or the Prospectus will conform, in all material respects, to the
     requirements of the Act and the Trust Indenture Act and the rules and
     regulations of the Commission thereunder and do not and will not, as of the
     applicable effective date as to the Registration Statement and any
     amendment thereto and as of the applicable filing date as to the Prospectus
     and any amendment or supplement thereto, contain an untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading;
     provided, however, that this representation and warranty shall not apply to
     any statements or omissions made in reliance upon and in conformity with
     information furnished in writing to Industries or the Company by any
     Underwriter through you expressly for use therein;

     (e) Neither Industries nor any of its subsidiaries has sustained since the
     date of the latest audited consolidated

                                      -3-
<PAGE>
 
     financial statements included or incorporated by reference in the
     Prospectus any material loss or interference with its business from fire,
     explosion, flood or other calamity, whether or not covered by insurance, or
     from any labor dispute or court or governmental action, order or decree,
     otherwise than as set forth or contemplated in the Prospectus; and, since
     the respective dates as of which information is given in the Registration
     Statement and the Prospectus, there has not been any material change in the
     consolidated share capital or long-term debt of Industries and its
     subsidiaries or the consolidated share capital or long-term debt of either
     the Company or Northern Indiana Public Service Company, a wholly-owned
     subsidiary of Industries ("Northern Indiana"), or any material adverse
     change, or any development involving a prospective material adverse change,
     in or affecting the general affairs, management, financial position,
     shareholders' equity or results of operations of the Company, Northern
     Indiana or Industries and its other subsidiaries, otherwise than as set
     forth or contemplated in the Prospectus;

     (f) Each of Industries, Northern Indiana and the Company has good and
     marketable title in fee simple to such of its fixed assets as are real
     property and good and marketable title to its other assets reflected in the
     most recent consolidated balance sheet incorporated by reference in the
     Prospectus, except properties and assets sold or otherwise disposed of in
     the ordinary course of business after the date of said balance sheet,
     subject to no mortgages, liens, charges or encumbrances of any kind
     whatsoever other than liens of current mortgages and minor defects and
     encumbrances customarily found in the case of properties of like size and
     character which do not impair the use of such properties by Industries,
     Northern Indiana or the Company, respectively;

     (g) Each of Industries, Northern Indiana and the Company has been duly
     incorporated and is validly existing as a corporation in good standing
     under the laws of the State of Indiana, with respective power and authority
     (corporate and other) to own its properties and conduct its business as
     described in the Prospectus, and has been duly qualified as a foreign
     corporation for the transaction of business and is in good standing under

          authenticated, issued and delivered and constitute valid and legally
          binding obligations of the Company entitled to the benefits provided
          by the Support Agreement and the Indenture; and the Securities, the
          Support Agreement and the Indenture conform to the descriptions
          thereof in the Prospectus;

                                      -14-
<PAGE>
 
               (7)  The Indenture has been duly authorized, executed and
          delivered by the Company and Industries and constitutes a valid and
          legally binding instrument, enforceable in accordance with its terms,
          subject, as to enforcement, to bankruptcy, insolvency, reorganization
          and other laws of general applicability relating to or affecting
          creditors' rights and to general equity principles; and the Indenture
          has been duly qualified under the Trust Indenture Act;

               (8)  The issue and sale of the Securities, the compliance by each
          of the Company and Industries with all of the provisions of the
          Securities, the Indenture, the Support Agreement and this Agreement,
          and the consummation of the transactions herein and therein
          contemplated, will not conflict with or result in a breach or
          violation of any the terms or provisions of, or constitute a default
          under, any indenture, mortgage, deed of trust, loan agreement or other
          agreement or instrument known to such counsel to which Industries or
          any of its subsidiaries is a party or by which Industries or any of
          its  subsidiaries is bound or to which any of the property or assets
          of Industries or any of its subsidiaries is subject, nor will such
          actions result in any violation of the provisions of the Articles of
          Incorporation or the By-Laws of Industries or any of its subsidiaries,
          or any statute, rule or regulation, or any order known to such counsel
          of any court or governmental agency or body having jurisdiction over
          Industries or any of its subsidiaries or any of their properties;

               (9)  No consent, approval, authorization, order, registration or
          qualification of or with any such court or governmental agency or body
          is required for the issue and sale of the Securities or the
          consummation by Industries or the Company of the transactions
          contemplated by this Agreement, the Support Agreement or the
          Indenture, except such as have been obtained under the Act and the
          Trust Indenture Act and such consents, approvals, authorizations,
          registrations or qualifications as may be required under state
          securities or Blue Sky laws in connection with the purchase and
          distribution of the Securities by the several Underwriters;

               (10)  The documents incorporated by reference in the Prospectus
          or any further amendment or supplement thereto made by Industries or
          the Company prior to the Time of Delivery (other than the financial
          statements and related schedules therein, as to which such counsel
          need express no opinion), when they became effective or

                                      -15-
<PAGE>
 
          were filed with the Commission, as the case may be, complied as to
          form in all material respects with the requirements of the Act or the
          Exchange Act, as applicable, and the rules and regulations of the
          Commission thereunder; and they have no reason to believe that any of
          such documents, when such documents became effective or were so filed,
          as the case may be, contained, in the case of a registration statement
          which became effective under the Act, 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, in the case of other documents which were filed under
          the Act or the Exchange Act with the Commission, an untrue statement
          of a material fact or omitted to state a material fact necessary in
          order to make the statements therein, in light of the circumstances
          under which they were made when such documents were so filed, not
          misleading;

               (11)  Giving effect to the interpretations of the requirements of
          the Act reflected in the No-Action Request and the Staff Response, the
          Registration Statement and the Prospectus and any further amendments
          and supplements thereto made by Industries or the Company prior to the
          Time of Delivery (other than the financial statements and related
          schedules therein, as to which such counsel need express no opinion)
          comply as to form in all material respects with the requirements of
          the Act and the Trust Indenture Act and the rules and regulations
          thereunder; they have no reason to believe that, as of its effective
          date, the Registration Statement or any further amendment thereto made
          by Industries or the Company prior to the Time of Delivery (other than
          the financial statements and related schedules therein, as to which
          such counsel need express no opinion) 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, as of its date, the Prospectus or any further
          amendment or supplement thereto made by Industries or the Company
          prior to the Time of Delivery (other than the financial statements and
          related schedules therein, as to which such counsel need express no
          opinion) contained an untrue statement of a material fact or omitted
          to state a material fact necessary to make the statements therein, in
          light of the circumstances under which they were made, not misleading
          or that, as of the Time of Delivery either the Registration Statement
          or the Prospectus or any further amendment or supplement thereto made
          by Industries or the Company prior to the

                                      -16-
<PAGE>
 
          Time of Delivery (other than the financial statements and related
          schedules therein, as to which such counsel need express no opinion)
          contains an untrue statement of a material fact or omits to state a
          material fact necessary to make the statements therein, in light of
          the circumstances under which they were made, not misleading; and they
          do not know of any amendment to the Registration Statement required to
          be filed or of any contracts or other documents of a character
          required to be filed as an exhibit to the Registration Statement or
          required to be incorporated by reference into the Prospectus or
          required to be described in the Registration Statement or the
          Prospectus which are not filed or incorporated by reference or
          described as required; and

               (12)  The statements made in the Prospectus which are stated
          therein to have been made on the basis of the opinion of such counsel
          have been reviewed by  such counsel and, as to matters of law and
          legal conclusions, are correct;

          (ii) Schiff Hardin & Waite shall also have furnished to you a letter,
     in form and substance satisfactory to you, authorizing the several
     Underwriters to rely on their opinion filed as Exhibit 8 to the
     Registration Statement as if such opinion were addressed to the several
     Underwriters and dated the Time of Delivery;

          (d) On the date of this Agreement and also at the Time of Delivery,
     Arthur Andersen & Co. shall have furnished to you a letter or letters,
     dated the respective dates of delivery thereof, in form and substance
     satisfactory to you, to the effect set forth in Annex I hereto;

          (e)  (i) Neither Industries nor any of its subsidiaries shall have
     sustained since the date of the latest audited financial statements
     included or incorporated by reference in the Prospectus any loss or
     interference with its business from fire, explosion, flood or other
     calamity, whether or not covered by insurance, or from any labor dispute or
     court or governmental action, order or decree, otherwise than as set forth
     or contemplated in the Prospectus, and (ii) since the respective dates as
     of which information is given in the Prospectus there shall not have been
     any change in the consolidated share capital or long-term debt of
     Industries or any of its subsidiaries or any change, or any development
     involving a prospective change, in or affecting the general affairs,
     management, financial position, shareholders' equity or results of
     operations of Industries and its subsidiaries, otherwise than as set forth
     or contemplated in the Prospectus, the effect of which, in any such case

                                      -17-
<PAGE>
 
     described in Clause (i) or (ii), is in your judgment so material and
     adverse as to make it impracticable or inadvisable to proceed with the
     public offering or the delivery of the Securities on the terms and in the
     manner contemplated in the Prospectus;

          (f) On or after the date hereof (i) no downgrading shall have occurred
     in the rating accorded any of Industries', Northern Indiana's or the
     Company's debt securities by any "nationally recognized statistical rating
     organization," as that term is defined by the Commission for purposes of
     Rule 436(g)(2) under the Act and (ii) no such organization shall have
     publicly announced that it has under surveillance or review, with possible
     negative implications, its rating of any of Industries', Northern Indiana's
     or the Company's debt securities;

          (g) On or after the date hereof there shall not have occurred any of
     the following:  (i) a suspension or material limitation in trading in
     securities generally or in trading in securities of Industries on the New
     York Stock Exchange; (ii) a general moratorium on commercial banking
     activities in New York declared by either Federal or New York State
     authorities; or (iii) the outbreak or escalation of hostilities involving
     the United States or the declaration by the United States of a national
     emergency or war if the effect of any such event specified in this Clause
     (iii) in your judgment makes it impracticable or inadvisable to proceed
     with the public offering or the delivery of the Securities on the terms and
     in the manner contemplated in the Prospectus; and

          (h) Each of Industries and the Company shall have furnished or caused
     to be furnished to you at the Time of Delivery certificates of officers of
     Industries and of the Company satisfactory to you as to the accuracy of the
     representations and warranties of Industries and the Company herein at and
     as of such Time of Delivery, as to the performance by Industries and the
     Company of all of their respective obligations hereunder to be performed at
     or prior to such Time of Delivery, as to the matters set forth in
     subsections (a), (e) and (f) of this Section and as to such other matters
     as you may reasonably request.

     8.   (a)  Industries and the Company will jointly and severally indemnify
and hold harmless each Underwriter against any losses, claims, damages or
liabilities to which such Underwriter may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration

                                      -18-
<PAGE>
 
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse each Underwriter for any legal or
other expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that neither the Company nor Industries shall be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in any Preliminary Prospectus,
the Registration Statement or the Prospectus or any such amendment or supplement
in reliance upon and in conformity with written information furnished to
Industries or the Company by any Underwriter through you expressly for use
therein.

     (b) Each Underwriter, severally and not jointly or jointly and severally,
will indemnify and hold harmless Industries and the Company against any losses,
claims, damages or liabilities to which Industries or the Company may become
subject, under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement or the Prospectus, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, in each case
to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission was made in any Preliminary
Prospectus, the Registration Statement or the Prospectus or any such amendment
or supplement in reliance upon and in conformity with written information
furnished to Industries or the Company by such Underwriter through you expressly
for use therein; and will reimburse Industries or the Company, as the case may
be, for any legal or other expenses reasonably incurred by it in connection with
investigating or defending any such action or claim as such expenses are
incurred.

     (c) In case any proceeding (including any governmental investigation) shall
be instituted involving any person in respect of which indemnity may be sought
pursuant to subsection (a) or (b) above, such person (the "indemnified party")
shall promptly notify the person or persons against whom such indemnity may be
sought (singly or collectively, as the case may be, the "indemnifying party") in
writing and the indemnifying party, upon request of the indemnified party, shall
retain counsel reasonably satisfactory to the indemnified party to represent the
indemnified party and any others the indemnifying party may

                                      -19-
<PAGE>
 
designate in such proceeding and shall pay the fees and disbursements of such
counsel related to such proceeding.  In any such proceeding, any indemnified
party shall have the right to retain its own counsel, but the fees and expenses
of such counsel shall be at the expense of such indemnified party unless (i) the
indemnifying party and the indemnified party shall have mutually agreed to the
retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them.
It is understood that the indemnifying party shall not, in respect of the legal
expenses of any indemnified party in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm (in addition to any local counsel) for all such
indemnified parties and that all such fees and expenses shall be reimbursed as
they are incurred.  Such firm shall be designated in writing by Morgan Stanley &
Co. Incorporated, in the case of parties indemnified pursuant to subsection (a)
above and by Industries, in the case of parties indemnified pursuant to
subsection (b) above.  The indemnifying party shall not be liable for any
settlement of any proceeding effected without its written consent, but if
settled with such consent or if there shall be a final judgment for the
plaintiff, the indemnifying party agrees to indemnify the indemnified party from
and against any loss or liability by reason of such settlement or judgment.
Notwithstanding the foregoing sentence, if at any time an indemnified party
shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel as contemplated by the second and third
sentences of this subsection (c), the indemnifying party agrees that it shall be
liable for any settlement of any proceeding effected without its written consent
if (i) such settlement is entered into more than 30 days after receipt by such
indemnifying party of the aforesaid request and (ii) such indemnifying party
shall not have reimbursed the indemnified party in accordance with such request
prior to the date of such settlement.  No indemnifying party shall, without the
prior written consent of the indemnified party, effect any settlement of any
pending or threatened proceeding in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such proceeding.

     (d) If the indemnification provided for in this Section 8 is unavailable to
or insufficient to hold harmless an indemnified party under subsection (a) or
(b) above in respect of any losses, claims, damages or liabilities (or actions
in respect thereof) referred to therein, then each indemnifying party shall

                                      -20-
<PAGE>
 
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (or actions in respect thereof)
in such proportion as is appropriate to reflect the relative benefits received
by Industries and the Company, on the one hand, and the Underwriters, on the
other, from the offering of the Securities.  If, however, the allocation
provided by the immediately preceding sentence is not permitted by applicable
law or if the indemnified party failed to give the notice required under
subsection (c) above, then each indemnifying party shall contribute to such
amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of Industries and the Company, on the one hand, and the Underwriters, on
the other, in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant equitable considerations.  The relative benefits received
by Industries and 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 total underwriting discounts and commissions received by the Underwriters,
in each case as set forth in the table on the cover page of the Prospectus.  The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by
Industries or the Company, on the one hand, or the Underwriters, on the other,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.  The Underwriters'
respective obligations to contribute pursuant to this Section 8 are several in
proportion to the respective principal amounts of Securities they have purchased
and not joint or joint and several.  Industries and the Company, on the one
hand, and the Underwriters, on the other, agree that it would not be just and
equitable if contribution pursuant to this subsection (d) were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to above in this subsection (d).  The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this subsection (d) shall be deemed to include 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
subsection (d), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Securities were
offered 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

                                      -21-
<PAGE>
 
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.

     (e) The obligations of Industries and the Company under this Section 8
shall be in addition to any liability which they may otherwise have and shall
extend, upon the same terms and conditions, to each person, if any, who controls
any Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 shall be in addition to any liability which
the Underwriters may otherwise have and shall extend, upon the same terms and
conditions, to each officer and director of Industries and of the Company and to
each person, if any, who controls Industries or the Company within the meaning
of the Act.

     9.   The respective indemnities, agreements, representations, warranties
and other statements of Industries, the Company and the Underwriters, as set
forth in this Agreement or made by them, respectively, pursuant to this
Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by any
Underwriter or any controlling person of such Underwriter, or Industries or the
Company, or any officer or director or controlling person of Industries or the
Company, and shall survive delivery of and payment for the Securities.

     10.  If for any reason the Securities are not delivered by or on behalf of
the Company as provided herein, Industries and the Company will reimburse the
Underwriters for all out-of-pocket expenses approved in writing by you,
including fees and disbursements of counsel, reasonably incurred by the
Underwriters in making preparations for the purchase, sale and delivery of the
Securities, but Industries and the Company shall then be under no further
liability to the Underwriters except as provided in Section 6 and Section 8
hereof.

     11.  All statements, requests, notices, and agreements hereunder shall be
in writing, and if to the Underwriters shall be delivered or sent by mail, telex
or facsimile transmission to Morgan Stanley & Co. Incorporated at 1585 Broadway,
New York, New York 10036, Attention:  Managing Director - Debt Syndicate
Department, facsimile no. (212) 761-0785; and if to Industries or the Company
shall be delivered or sent by mail, telex or facsimile transmission to the
address of Industries or the Company set forth in the Registration Statement,
Attention:  Treasurer, facsimile no. (219) 853-5352.  Any such statements,
requests, notices or agreements shall take effect upon receipt thereof.

                                      -22-
<PAGE>
 
     12.  This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, Industries and the  Company and, to the extent provided in
Section 8 and Section 9 hereof, the officers and directors of Industries and of
the Company and each person who controls Industries or the Company or any
Underwriter, and their respective heirs, executors, administrators, successors
and assigns, and no other person shall acquire or have any right under or by
virtue of this Agreement.  No purchaser of any of the Securities from the
Underwriter shall be deemed a successor or assign by reason merely of such
purchase.

     13.  Time shall be of the essence of this Agreement.  As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

     14.  This Agreement shall be governed by and construed in accordance with
the laws of the State of New York.

                                      -23-

     15.  This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such respective counterparts shall together constitute one and
the same instrument.

     If the foregoing is in accordance with your understanding, please sign and
return to us four counterparts hereof, and upon the acceptance hereof by you,
this letter and such acceptance hereof shall constitute a binding agreement
between the Underwriter, on the one hand, and Industries and the Company, on the
other.

                              Very truly yours,

                                    -------

     Pursuant to Section 7(d) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

     (i)  They are independent certified public accountants with respect to
Industries within the meaning of the Act and the applicable published rules and
regulations thereunder, and as such certified public accountants, audit the
books of Industries and its subsidiaries;

     (ii)  In their opinion, the financial statements and schedules audited by
them and included or incorporated by reference in the Registration Statement or
the Prospectus comply as to form in all material respects with the applicable
accounting requirements of the Act or the Exchange Act, as applicable, and the
related published rules and regulations thereunder;

     (iii)  In their opinion, any of the unaudited selected financial
information with respect to the consolidated results of operations and financial
position of Industries and its subsidiaries for the five most recent fiscal
years that is included in the Prospectus or included or incorporated by
reference in Item 6 of Industries' Annual Report on Form 10-K for the most
recent fiscal year agrees with the corresponding amounts (after restatement
where applicable) in the audited consolidated financial statements for such five
fiscal years which were included or incorporated by reference in Industries'
Annual Reports on Form 10-K for such fiscal years;

     (iv)  On the basis of limited procedures, not constituting an audit in
accordance with generally accepted auditing standards, consisting of procedures
specified by the American Institute of Certified Public Accountants for a review
of interim financial information as described in Statement of Auditing Standards
No. 71, "Interim Financial Information" of the unaudited financial statements
and a reading of other information referred to below, inspection of the minute
books of Industries and its subsidiaries since the date of the latest audited
financial statements included or incorporated by reference in the Prospectus,
inquiries of officials of Industries and its subsidiaries responsible for
financial and accounting matters and such other inquiries and procedures as may
be specified in such letter, nothing came to their attention that caused them to
believe that:

entitled to give or take any request, demand, authorization, direction, notice,
consent, waiver or other action, or to vote on any action, authorized or
permitted to be given or taken by Holders of Securities of such series. If not
set by the Company prior to the first solicitation of a Holder of Securities of
such series made by any Person in respect of any such action, or in the case of
any such vote, prior to such vote, the record date for any such action or vote
shall be the 30th day prior to such first solicitation or vote, or, if later,
the date of the most recent list of Holders required to be provided pursuant to
Section 701, as the case may be. With regard to any record date for action to be
taken by the Holders of one or more series of Securities, only the Holders of
Securities of such series on such date (or their duly designated proxies) shall
be entitled to give or take, or vote on, the relevant action.

     The Trustee shall fix a record date for the purpose of determining the
Persons who are beneficial owners of interests in any permanent Global Security
held by a Depositary and who are entitled under the procedures of such
Depositary to make, give or take, by a proxy or proxies duly appointed in
writing, any request, demand, authorization, direction, notice, consent, waiver
or other action provided in or pursuant to this Indenture to be made, given or
taken by Holders. If such a record date is fixed, the Holders on such record
date or their duly appointed proxy or proxies, and only such Persons, shall be
entitled to make, give or take such request, demand, authorization, direction,
notice, consent, waiver or other action, whether or not such Holders remain
Holders after such record date. No such request, demand, authorization,
direction, notice, consent, waiver or other action shall be valid or effective
if made, given or taken more than 90 days after such record date.

     (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved in any reasonable manner which the Trustee deems
sufficient.

     (c) The principal amount and serial numbers of Bearer Securities held by
any Person executing any such instrument or writing as a Holder of Securities,
and the date of his holding the same, may be proved by the production of such
Bearer Securities or by a certificate executed, as depositary, by any trust
company, bank, banker or other depositary, wherever situated, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at
the date therein mentioned such Person had on deposit with such depositary,

                                     -11-
<PAGE>
 
or exhibited to it, the Bearer Securities therein described; or such facts may
be proved by the certificate or affidavit of the Person executing such
instrument or writing as a Holder of Securities, if such certificate or
affidavit is deemed by the Trustee to be satisfactory. The Trustee, the Company
and Industries may assume that such ownership of any Bearer Security continues
until (1) another certificate or affidavit bearing a later date issued in
respect of the same Bearer Security is produced, or (2) such Bearer Security is
produced to the Trustee by some other Person, or (3) such Bearer Security is
surrendered in exchange for a Registered Security, or (4) such Bearer Security
is no longer Outstanding.

     (d) The fact and date of execution of any such instrument or writing, the
authority of the Person executing the same, the principal amount and serial
numbers of Bearer Securities held by the Person so executing such instrument or
writing and the date of holding the same may also be proved in any other
reasonable manner which the Trustee deems sufficient; and the Trustee may in any
instance require further proof with respect to any of the matters referred to in
this Section.

     (e) The principal amount and serial numbers of Registered Securities held
by any Person, and the date of holding the same, shall be proved by the Security
Register.

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

SECTION 105.  Notices, etc., to Trustee, Company and Industries.

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

          (1) the Trustee by any Holder of a Security or by the Company or
     Industries 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, Attention: Corporate Trust Department, or

          (2) the Company or Industries, as the case may be, by the Trustee or
     by any Holder of a Security shall be sufficient for every purpose hereunder
     (unless otherwise herein expressly provided) if in writing and mailed,
     first-class postage prepaid, to the Company or Industries, as the case may
     be, addressed to the attention of its Corporate Secretary, at 5265 Hohman
     Avenue, Hammond, Indiana 46320, or at any other address previously
     furnished in writing to the Trustee by the Company or Industries, as the
     case may be.

SECTION 106.  Notice to Holders of Securities; Waiver.

     Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of Securities of any event:

          (1) such notice shall be sufficiently given to Holders of Registered
     Securities if in writing and mailed, first-class postage prepaid, to each
     Holder of a Registered Security affected by such event, at his address as
     it appears in the Security Register, not later than the latest date, and
     not earlier than the earliest date, prescribed for the giving of such
     Notice; and

          (2) such notice shall be sufficiently given to Holders of Bearer
     Securities if published in an Authorized Newspaper in The City of New York
     and, if the Securities of such series are then listed on The Stock Exchange
     of the United Kingdom and the Republic of Ireland and such stock exchange
     shall so require, in London and, if the Securities of such series are then
     listed on the Luxembourg Stock Exchange and such stock exchange shall so
     require, in Luxembourg and, if the Securities of such series are then
     listed on any other stock exchange outside the United States and such stock
     exchange shall so require, in any other required city outside the United
     States or, if not practicable, in Europe on a Business Day at least twice,
     the first such publication to be not earlier than the earliest date and not
     later than the latest date prescribed for the giving of such notice.

     In case by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder. In any case where notice
to Holders of Registered Securities is given by mail, neither the failure to
mail such notice, nor any defect in any notice so mailed, to any particular
Holder of a Registered Security shall affect the sufficiency of such notice with
respect to other Holders of Registered Securities or the sufficiency of any
notice by publication to Holders of Bearer Securities given as provided above.

     In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders of

                                     -13-
<PAGE>
 
Securities shall be filed with the Trustee, but such filing shall not be a
condition precedent to the validity of any action taken in reliance upon such
waiver.

SECTION 107.  Language of Notices, etc.

     Any request, demand, authorization, direction, notice, consent, election or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

SECTION 108.  Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.

SECTION 109.  Effect of Headings and Table of Contents.

     The Article and Section headings herein and the Table of Contents are for

of the remaining provisions shall not in any way be affected or impaired
thereby.

     Nothing in this Indenture or the Securities or coupons, express or implied,
shall give to any Person, other than the parties hereto, their successors
hereunder and the Holders of Securities and coupons, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

SECTION 114.  Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
or coupons) payment of interest or principal (and premium, if any) need not be
made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity, provided that no interest shall accrue on the amount so payable for
the period from and after such Interest Payment Date, Redemption Date or Stated
Maturity, as the case may be.

SECTION 115.  Appointment of Agent for Service.

hereby appoint the Trustee as their agent upon which process may be served in

Trustee and such successor's acceptance of such appointment. The Company and
Industries further agree to take any and all action, including the execution and
filing of any and all such documents and instruments, as may be necessary to
continue such designation and appointment of such agent or successor.

     By the execution and delivery of this Indenture, the Trustee hereby agrees
to act as such agent and undertakes promptly to notify the Company and
Industries of receipt by it of service of process in accordance with this
Section.

signature of the Treasurer or any Assistant Treasurer of the Company.

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 after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed on behalf
of the Company to the Trustee for authentication by the Trustee together with an
Order of the Company for the authentication and delivery of such Securities, and
the Trustee in accordance with such Order shall authenticate and deliver such
Securities; provided, however, that, in connection with its original issuance, a
Bearer Security may be delivered only outside the United States and only if the
Trustee shall have received from the person entitled to receive such Bearer
Security a certificate in the form required by Section 311.  The maturity dates,
original issue dates, interest rates and any other terms of the Securities of
such series shall be determined by or pursuant to such Order and procedures.  If
provided for in such procedures, such Order may authorize authentication and
delivery pursuant to oral instructions from the

                                     -21-

<PAGE>
 
Company or its duly authorized agent, which instructions shall be promptly
confirmed in writing.

     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 Sections 315(a) through
315(d) of the Trust Indenture Act) shall be fully protected in relying upon:

          (a) the Board Resolution of the Company or indenture supplemental
     hereto establishing the form of the Securities of that series pursuant to
     Section 201 and the terms of the Securities of that series pursuant to
     Section 301;

          (b) an Officers' Certificate pursuant to Sections 201 and 301 and
     complying with Section 102;

          (c) an Opinion of Counsel complying with Section 102 stating,

               (i) that the forms of such Securities and coupons, if any, have
          been established by or pursuant to a Board Resolution of the Company
          or by an indenture supplemental hereto, as permitted by Section 201
          and in conformity with the provisions of this Indenture;

               (ii) that the terms of such Securities have been established by
          or pursuant to a Board Resolution of the Company or by an indenture
          supplemental hereto, as permitted by Section 201 and Section 301 and
          in conformity with the provisions of this Indenture;

               (iii)  that such Securities, together with the coupons
          appertaining thereto, if any, have been duly authorized, executed,
          authenticated, issued and delivered and constitute valid and legally
          binding obligations of the Company entitled to the benefits provided
          by the Support Agreement and the Indenture, enforceable in accordance
          with their respective terms, except to the extent that the enforcement
          of such obligations may be subject to bankruptcy laws or insolvency
          laws or other similar laws and to the exercise of judicial discretion
          in accordance with general principles of equity;

               (iv) that all laws and requirements in respect of the execution
          and delivery of the Securities have been complied with; and

               (v) such other matters as the Trustee may reasonably request.

     With respect to each issuance of Securities of a series  established in
accordance with the final paragraph of Section 301, the Trustee may conclusively
rely on the documents and opinion delivered in connection with the initial
issuance thereof pursuant to Sections 201

                                     -22-

<PAGE>
 
and 301 and this Section 303, as applicable (unless revoked by superseding
comparable documents or opinions), as to the authorization of the Board of
Directors of any Securities delivered hereunder, the form thereof and the
legality, validity, binding effect and enforceability thereof.

     With respect to Securities of a series established in accordance with the
final paragraph of Section 301, if the form and general terms of the Securities
of such series have been established by or pursuant to one or more Board
Resolutions of the Company or by an indenture supplemental hereto, as permitted
by Sections 201 and 301, 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 Sections 315(a)
through 315(d) of the Trust Indenture Act) shall be fully protected in relying
upon, in addition to the foregoing documents and Opinion of Counsel, or in lieu
of clause (iii) above, an Opinion of Counsel stating that the Securities have
been duly authorized by the Company and, when duly executed by the Company and
completed and authenticated by the Trustee in accordance with the Indenture and
issued, delivered and paid for in accordance with any applicable distribution
agreement, will have been duly issued under the Indenture and will constitute
valid and legally binding obligations of the Company entitled to the benefits
provided by the Support Agreement and the Indenture, enforceable in accordance
with their respective terms, except to the extent that the enforcement of such
obligations may be subject to bankruptcy laws or insolvency laws or other
similar laws and to the exercise of judicial discretion in accordance with
general principles of equity.

     If such forms or terms have been so established by or pursuant to a Board
Resolution of the Company or by an indenture supplemental hereto as permitted by
Sections 201 and 301, the Trustee shall have the right to decline to
authenticate and deliver any Securities of such series:

          (i) if the Trustee, being advised by counsel, determines that such
     action may not lawfully be taken;

          (ii) if the Trustee in good faith by its board of directors, executive
     committee or a trust committee of directors or Responsible Officers of the
     Trustee in good faith determines that such action would expose the Trustee
     to personal liability to Holders of any outstanding series of Securities;
     or

          (iii)  if the issue of such Securities pursuant to this Indenture will
     affect the Trustee's own rights, duties and immunities under the Securities
     and this Indenture or otherwise in a manner which is not reasonably
     acceptable to the Trustee.

     If the Company shall establish pursuant to Section 301 that the Securities
of a series are to be issued in whole or in part in the form of one or more
Global Securities, then the Company shall execute and the Trustee shall, in
accordance with this Section and the Order of the Company with respect to such
series, authenticate and deliver one or more Global

                                     -23-

<PAGE>
 
Securities in permanent form that (i) shall represent and shall be denominated
in an amount equal to the aggregate principal amount of the Outstanding
Securities of such series to be represented by such Global Security or
Securities, (ii) shall be registered, if in registered form, in the name of the
Depositary for such Global Security or Securities or the nominee of such
Depositary, (iii) shall be delivered by the Trustee to such Depositary or
pursuant to such Depositary's instruction and (iv) shall bear a legend as
required by Section 204.

     Each Registered Security shall be dated the date of its authentication.
Each Global Security, each Bearer Security and any temporary Bearer Security in
global form shall be dated as of the date specified as contemplated by Section
301.

     No Security or coupon shall be entitled to any benefit under this Indenture
or be valid or obligatory for any purpose unless there appears on such Security
a certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder and is entitled to the
benefits of this Indenture.  Except as permitted by Section 306 or 307, the
Trustee shall not authenticate and deliver any Bearer Security unless all
appurtenant coupons for interest then matured and paid or payment duly provided
for, have been detached and canceled.

SECTION 304.  Temporary Securities.

     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon an Order of the Company the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form or, if authorized, in bearer form with one or
more coupons or without coupons, and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Securities may determine, as evidenced by their execution of such Securities.
Such temporary Securities may be in global form.

     Except in the case of temporary Securities in global form, which shall be
exchanged in accordance with the provisions thereof, if temporary Securities of
any series are issued, the Company will cause definitive Securities of that
series to be prepared without unreasonable delay.  After the preparation of
definitive Securities of such series, the temporary Securities of such series
shall be exchangeable for definitive Securities of such series upon surrender of
the temporary Securities of such series at the office or agency of the Company
in a Place of Payment for that series, without charge to the Holder.  Upon
surrender for cancellation of any one or more temporary Securities of any series
(accompanied by any unmatured coupons appertaining thereto), the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor (at
an office or agency of the Company in the case of Bearer Securities) a like
principal amount of definitive Securities of the same series

                                     -24-

<PAGE>
 
of authorized denominations and of like tenor; provided, however, that no
definitive Bearer Security shall be delivered in exchange for a temporary
Registered Security; and provided, further, that no definitive Bearer Security
shall be delivered in exchange for a temporary Bearer Security unless the
Trustee shall have received from the Person entitled to receive the definitive
Bearer Security a certificate in the form required by Section 311.  Until so
exchanged, the temporary Securities of any series, including temporary
Securities in global form, shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities of such series.

SECTION 305.  Registration, Registration of Transfer and Exchange .

     The Company shall cause to be kept at one of its offices or agencies
designated pursuant to Section 1002 a register (referred to as the "Security
Register") in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of Registered
Securities and of transfers of Registered Securities.  Said office or agency is
hereby appointed the Security Registrar for the purpose of registering
Registered Securities and transfers of Registered Securities as herein provided.

     Upon surrender for registration of transfer of any Registered Security of
any series at the office or agency in a Place of Payment maintained for such
purpose for such 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 Registered Securities of the same series, Stated
Maturity and original issue date, of any authorized denominations and of like
tenor and aggregate principal amount.

     At the option of the Holder, Registered Securities of any series (except a
Global Security representing all or a portion of such series) may be exchanged
for Registered Securities of the same series, Stated Maturity and original issue
date, of any authorized denominations and of like tenor and aggregate principal
amount, upon surrender of the Securities to be exchanged at any such office or
agency.

     At the option of the Holder, Bearer Securities of any series may be
exchanged for Registered Securities of the same series, Stated Maturity and
original issue date, of any authorized denominations and of like tenor and
aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any such office or agency, with all unmatured coupons and all
matured coupons in default thereto appertaining.  If the Holder of a Bearer
Security is unable to produce any such unmatured coupon or coupons or matured
coupon or coupons in default, such exchange may be effected if the Bearer
Securities are accompanied by payment in funds acceptable to the Company and the
Trustee in an amount equal to the face amount of such missing coupon or coupons,
or the surrender of such missing coupon or coupons may be waived by the Company
and the Trustee if there be furnished to them such security or indemnity as they
may require to save each of them and any Paying Agent harmless.  If thereafter
the Holder of such Security shall surrender to any Paying Agent any such missing
coupon in respect of which such a payment shall have been

                                     -25-

<PAGE>
 
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 1002, interest
represented by coupons shall be payable only upon presentation and surrender of
those coupons at an office or agency located outside the United States.
Notwithstanding the foregoing, in case a Bearer Security of any series is
surrendered at any such office or agency in exchange for a Registered Security
of the same series after the close of business at such office or agency on (i)
any Regular Record Date and before the opening of business at such office or
agency on the relevant Interest Payment Date, or (ii) any Special Record Date
and before the opening of business at such office or agency on the related
proposed date for payment of Defaulted Interest, such Bearer Security shall be
surrendered without the coupon relating to such Interest Payment Date or
proposed date of payment, as the case may be.

     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.

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

     Every Registered Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company or the Trustee) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar 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
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 of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

     The Company shall not be required (i) to issue, to register the transfer of
or to exchange Securities of any series during a period of 15 Business Days
immediately preceding the date notice is given identifying the serial numbers of
the Securities of that series called for redemption, or (ii) to issue, to
register the transfer of or to exchange any Registered Security so selected for
redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part, or (iii) to exchange any Bearer Security so selected for
redemption except that such a Bearer Security may be exchanged for a Registered
Security of that series, provided that such Registered Security shall be
immediately surrendered for redemption with written instruction for payment
consistent with the provisions of this Indenture.

                                     -26-

<PAGE>
 
     Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any Global Security shall be exchangeable pursuant
to this Section 305 or Sections 304, 306, 906 or 1107 for Securities registered
in the name of, and a transfer of a Global Security of any series may be
registered to, any Person other than the Depositary for such Global Security or
its nominee only if:

          (i) such Depositary notifies the Company that it is unwilling or
     unable to continue as Depositary for such Global Security or if at any time
     such Depositary ceases to be a clearing agency registered under the
     Securities Exchange Act of 1934, as amended, and a successor Depositary is
     not appointed by the Company within 60 days;

          (ii) the Company executes and delivers to the Trustee an Order of the
     Company that such Global Security shall be so exchangeable and the transfer
     thereof so registrable; or

          (iii)  there shall have occurred and be continuing an Event of Default
     or an event which, with the giving of notice or lapse of time, would
     constitute an Event of Default with respect to the Securities of such
     series.

Upon the occurrence in respect of any Global Security of any series of any one
or more of the conditions specified in clauses (i), (ii) or (iii) of the
preceding sentence or such other conditions as may be specified as contemplated
by Section 301 for such series, then without unnecessary delay, but in any event
not later than the earliest date on which such interests may be so exchanged,
the Company shall deliver to the Trustee definitive Securities of that series in
aggregate principal amount equal to the principal amount of such Global
Security, executed by the Company.

     On or after the earliest date on which such interests may be so exchanged,
such Global Securities shall be surrendered from time to time by the Depositary
and in accordance with instructions given to the Trustee and the Depositary
(which instructions shall be in writing but need not be contained in or
accompanied by an Officers' Certificate or be accompanied by an Opinion of
Counsel), as shall be specified in the Order of the Company with respect thereto
to the Trustee, as the Company's agent for such purpose, to be exchanged, in
whole or in part, for definitive Securities of the same series without service
charge.  The Trustee shall authenticate and make available for delivery, in
exchange for each portion of such surrendered Global Security, a like aggregate
principal amount of definitive Securities of the same series of authorized
denominations and of like tenor as the portion of such Global Security to be
exchanged which (unless the Securities of the series are not issuable both as
Bearer Securities and as Registered Securities, in which case the definitive
Securities exchanged for the Global Security shall be issuable only in the form
in which the Securities are issuable, as specified as contemplated by Section
301) shall be in the form of Bearer Securities or Registered Securities, or any
combination thereof, as shall be specified by the beneficial owner thereof;
provided, however, that no such exchanges may

                                     -27-

<PAGE>
 
occur during a period beginning at the opening of business 15 Business Days
before any selection of Securities of that series to be redeemed and ending on
the relevant Redemption Date; and provided, further, that (unless otherwise
specified as contemplated by Section 301) no Bearer Security delivered in
exchange for a portion of a Global Security shall be mailed or otherwise
delivered to any location in the United States.

     Promptly following any such exchange in part, such Global Security shall be
returned by the Trustee to the Depositary in accordance with the instructions of
the Company referred to above.  If a Registered Security is issued in exchange
for any portion of a Global Security after the close of business at the office
or agency where such exchange occurs on (i) any Regular Record Date for such
Security and before the opening of business at such office or agency on the next
Interest Payment Date, or (ii) any Special Record Date for such Security and
before the opening of business at such office or agency on the related proposed
date for payment of interest or Defaulted Interest, as the case may be, interest
shall not be payable on such Interest Payment Date or proposed date for payment,
as the case may be, in respect of such Registered Security, but shall be payable
on such Interest Payment Date or proposed date for payment, as the case may be,
only to the Person to whom interest in respect of such portion of such Global
Security is payable in accordance with the provisions of this Indenture.

SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security or a Security with a mutilated coupon
appertaining to it is surrendered to the Trustee, the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a new Security
of the same series, Stated Maturity and original issue date, and of like tenor
and principal amount and bearing a number not contemporaneously outstanding,
with coupons corresponding to the coupons, if any, appertaining to the
surrendered Security.

     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 or coupon
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 or coupon has been acquired by a
bona fide purchaser, the Company shall execute and upon its request the Trustee
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security or in exchange for the Security to which a destroyed, lost or stolen
coupon appertains (with all appurtenant coupons not destroyed, lost or stolen),
a new Security of the same series, Stated Maturity and original issue date, and
of like tenor and principal amount and bearing a number not contemporaneously
outstanding, with coupons corresponding to the coupons, if any, appertaining to
such destroyed, lost or stolen Security or to the Security to which such
destroyed, lost or stolen coupon appertains.

     In case any such mutilated, destroyed, lost or stolen Security or coupon
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing

                                     -28-

<PAGE>
 
a new Security, pay such Security or coupon; provided, however, that payment of
principal of (and premium, if any) and any interest on Bearer Securities shall,
except as otherwise provided in Section 1002, be payable only at an office or
agency located outside the United States; and provided, further, that, with
respect to any such coupons, interest represented thereby (but not any
additional amounts payable as provided in Section 1004), shall be payable only
upon presentation and surrender of the coupons appertaining thereto.

     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) connected therewith.

     Every new Security of any series, with its coupons, if any, issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen coupon appertains,
shall constitute an original additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Security and its coupons, if any,
or the destroyed, lost or stolen coupon shall be at any time enforceable by
anyone, and any such new Security and coupons, if any, shall be entitled to all
the benefits of this Indenture equally and proportionately with any and all
other Securities of that series and their coupons, if any, 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 or coupons.

SECTION 307.  Payment of Interest; Interest Rights Preserved.

     Unless otherwise provided as contemplated by Section 301 with respect to
any series of Securities, interest on any Registered Security which is payable,
and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.  Interest, if any, is paid on Bearer Securities to holders of
coupons.  In case a Bearer Security of any series is surrendered in exchange for
a Registered Security of such series after the close of business (at an office
or agency in a Place of Payment for such series) on any Regular Record Date and
before the opening of business (at such office or agency) on the next succeeding
Interest Payment Date, such Bearer Security shall be surrendered without the
coupon relating to such Interest Payment Date and interest will not be payable
on such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but will be payable only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.

     Any interest on any Registered 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

                                     -29-

<PAGE>
 
Regular Record Date by virtue of having been such Holder, and such Defaulted
Interest may be paid by the Company, at its election in each case, as provided
in clause (1) or (2) below:

          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Registered 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 Registered 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 provided in
     this clause.  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 Registered Securities of such series at the address of
     such Holder as it appears in the Security Register, not less than 10 days
     prior to such Special Record Date.  The Trustee may, in its discretion, in
     the name and at the expense of the Company, cause a similar notice to be
     published at least once in an Authorized Newspaper in each Place of
     Payment, but such publication shall not be a condition precedent to the
     establishment of such Special Record Date.  Notice of the proposed payment
     of such Defaulted Interest and the Special Record Date therefor having been
     so mailed, such Defaulted Interest shall be paid to the Persons in whose
     names the Registered 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).  In case a Bearer Security of any series is
     surrendered at the office or agency in a Place of Payment for such series
     in exchange for a Registered Security of such series after the close of
     business at such office or agency on any Special Record Date and before the
     opening of business at such office or agency on the related proposed date
     for payment of Defaulted Interest, such Bearer Security shall be
     surrendered without the coupon relating to such proposed date of payment
     and Defaulted Interest will not be payable on such proposed date of payment
     in respect of the Registered Security issued in exchange for such Bearer
     Security, but will be payable only to the Holder of such coupon when due in
     accordance with the provisions of this Indenture.

                                     -30-

<PAGE>
 
          (2) The Company may make payment of any Defaulted Interest on the
     Securities of any series 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, such manner of payment shall be deemed practicable by the
     Trustee.

     Subject to the foregoing provisions of this Section, 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 308.  Persons Deemed Owners.

     Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any authorized agent of the Company or
the Trustee may deem and treat the Person in whose name such Registered Security
is registered as the absolute owner of such Registered Security for the purpose
of receiving payment of principal of (and premium, if any) and (subject to
Section 307) 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 authorized agent of the Company or the Trustee shall be affected by any
notice to the contrary.

     The Company, the Trustee and any agent of the Company or the Trustee may
treat the bearer of any Bearer Security and the bearer of any coupon as the
absolute owner of such Security or coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever, whether or
not such Security or coupon 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 (or its nominee) shall have any rights under this
Indenture with respect to such Global Security or any Security represented
thereby, 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 or any
Security represented thereby for all purposes whatsoever.  None of the Company,
the Trustee, any Paying Agent or the Security Registrar will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests of a Global Security
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

                                      -31-
<PAGE>
 
SECTION 309.  Cancellation.

     All Securities and coupons surrendered for payment, redemption,
registration of transfer or exchange or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee and shall be promptly canceled by the Trustee.  The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Securities so delivered shall be promptly canceled by
the Trustee.  No Securities shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section, except as expressly
permitted by this Indenture.  All canceled Securities and coupons held by the
Trustee shall be destroyed and certification of their destruction delivered to
the Company, unless by an Order the Company shall direct that canceled
Securities be returned to it.

     The repayment of any principal amount of Securities pursuant to such option
of the Holder to require repayment of Securities before their Stated Maturity,
for purposes of this Section 309, shall not operate as a payment, redemption or
satisfaction of the indebtedness represented by such Securities unless and until
the Company, at its option, shall deliver or surrender the same to the Trustee
with an Order that such Securities be canceled.

SECTION 310.  Computation of Interest.

                           SATISFACTION AND DISCHARGE

SECTION 401.  Satisfaction and Discharge of Indenture.

     This Indenture shall upon a Request of the Company cease to be of
further effect (except as to any surviving rights of registration of transfer or
exchange of Securities herein expressly provided for, and any right to receive
additional amounts, as provided in Section 1004), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when:

          (1)  either

               (A) all Securities theretofore authenticated and delivered and
     all coupons appertaining thereto (other than (i) coupons appertaining to
     Bearer Securities surrendered for exchange for Registered Securities and
     maturing after such exchange, whose surrender is not required or has been
     waived as provided in Section 305, (ii) Securities and coupons which have
     been destroyed, lost or stolen and which have been replaced or paid as
     provided in Section 306, (iii) coupons appertaining to Securities called
     for redemption and maturing after the relevant Redemption Date, whose
     surrender has been waived as provided in Section 1106, and (iv) Securities
     and coupons 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 1003) have
     been delivered to the Trustee for cancellation; or

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

               (i)  have become due and payable, or

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

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

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

                                      -34-
<PAGE>
 
     Securities which have become due and payable) or to the Stated Maturity or
     Redemption Date, as the case may be;

          (2) in the event that the Company has deposited funds with the Trustee
     pursuant to paragraph (1)(B) above, at the time of such deposit, (A) no
     default in the payment of principal, premium, interest or any other payment
     due on any Senior Indebtedness shall have occurred and be continuing, (B)
     no acceleration of the maturity of any Senior Indebtedness shall have
     occurred because of a default (unless such acceleration shall have been
     subsequently revoked, in accordance with the instrument evidencing such
     Senior Indebtedness, or such Senior Indebtedness shall have been paid in
     full or payment therefor shall have been duly provided) and (C) no other
     event with respect to any Senior Indebtedness shall have occurred and be
     continuing which, after the giving of notice or the lapse of time or both,
     would permit the holders of such Senior Indebtedness or a trustee on behalf
     of such holders to accelerate the maturity of such Senior Indebtedness;

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

          (4) the Company has delivered to the Trustee an Officers' Certificate
     of the Company and an Opinion of Counsel, each stating that all conditions
     precedent herein provided for relating to the satisfaction and discharge of
     this Indenture have been complied with.

     In the event there are Securities of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so with respect to
Securities of all series as to which it is Trustee and if the other conditions
thereto are met.  In the event there are two or more Trustees hereunder, then
the effectiveness of any such instrument shall be conditioned upon receipt of
such instruments from all Trustees hereunder.

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company and Industries to the Trustee under Section 607, the
obligations of the Trustee to any Authenticating Agent under Section 614 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 Sections 305,
306, 402, 1002 and 1003 shall survive.

SECTION 402.  Application of Trust Money.

     Subject to the provision of the last paragraph of Section 1003, all money
deposited with the Trustee pursuant to Section 401 shall be held in trust and
applied by it, in accordance with the provisions of the Securities, the coupons
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

                                      -35-
<PAGE>
 
principal (and premium, if any) and interest for whose payment such money has
been deposited with the Trustee, but such money need not be segregated from
other funds, except to the extent required by law.

          (4) the Company or Industries defaults in the performance or breach of

     this Section specifically dealt with or which has expressly been included
     in or pursuant to this Indenture solely for the benefit of one or more
     series of Securities other than that series), and continuance of such
     default or breach for a period of 30 days after there has been given, by
     registered or certified mail, to the Company and Industries by the Trustee,
     or to the Company, Industries and the Trustee by the Holders of at least
     25% in principal amount of the Outstanding Securities of that series, a
     written notice specifying such default or breach and requiring it to be
     remedied and stating that such notice is a "Notice of Default" hereunder;
     provided, however, that the Trustee shall not be deemed to have knowledge
     of such default unless either (A) a Responsible Officer of the Trustee
     assigned to the Corporate Trust Department (or any successor division or
     department of the Trustee) shall have actual knowledge of such default, or
     (B) the

                                      -36-
<PAGE>
 
     Trustee shall have received written notice thereof from the Company or from
     any Holder of Outstanding Securities of that series; or

          (5) the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in respect of any of the Company, Industries or
     Northern Indiana in an involuntary case or proceeding under any applicable

     law or (B) a decree or order adjudging any of the Company, Industries or
     Northern Indiana a bankrupt or insolvent, or approving as properly filed a
     petition by one or more Persons other than the Company, Industries,
     Northern Indiana or any of their Affiliates seeking reorganization,

     of any of the Company, Industries or Northern Indiana, or ordering the
     liquidation or winding up of the affairs of any of the Company, Industries
     or Northern Indiana, and the continuance of any such decree or order for
     relief or any such other decree or order unstayed and in effect for a
     period of 60 consecutive days; or

          (6) the commencement by any of the Company, Industries or Northern
     Indiana of a case or proceeding under any applicable Federal or State
     bankruptcy, insolvency, reorganization or other similar law or of any other
     case or proceeding to be adjudicated a bankrupt or insolvent, or the
     consent by it to the entry of a decree or order for relief in respect of it
     in a case or proceeding under any applicable Federal or State bankruptcy,
     insolvency, reorganization or other similar law or to the commencement of
     any bankruptcy or insolvency case or proceeding against it, or the filing
     by it of a petition or answer or consent seeking reorganization or relief
     under any applicable Federal or State law, or the consent by it to the
     filing of such petition or to the appointment of or taking possession by a
     custodian, receiver, liquidator, assignee, trustee, sequestrator or similar
     official in respect of it or any substantial part of its property, or the
     making by it of an assignment for the benefit of creditors, or its
     admission in writing of its inability to pay its debts generally as they
     become due, or its taking of corporate action in furtherance of any such
     action; or

          (7) any other Event of Default provided with respect to Securities of
     that series.

SECTION 502.  Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the
Trustee or the Holders of not less than 33% in principal amount of the
Outstanding Securities of that series may declare the principal amount (or,
if the Securities of that series are Original Issue Discount Securities,

                                      -37-
<PAGE>
 
such portion of the principal amount as may be specified in the terms of that
series) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company and Industries (and to the
Trustee if given by Holders), and upon any such declaration such principal
amount (or specified amount) shall become 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 principal amount of the
Outstanding Securities of that series, by written notice to the Company,
Industries and the Trustee, may rescind and annul such declaration and its
consequences if:

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

               (A) all overdue interest on all Securities of that series;

               (B) the principal of (and premium, if any, on) any Securities of
          that series which have become due otherwise than by such declaration
          of acceleration and interest thereon at the rate or rates prescribed
          therefor in such Securities; and

               (C) to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate or rates prescribed
          therefor in such Securities; and

               (D) all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel, and any other amounts due to the
          Trustee under Section 607;

     and

          (2) all Events of Default with respect to Securities of that series,
     other than the non-payment of the principal of Securities of that series
     which have become due solely by such declaration of acceleration, have been
     cured or waived as provided in Section 513.

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

                                      -38-
<PAGE>
 
SECTION 503.  Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if:

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

          (2) default is made in the payment of the principal of (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 and coupons, the whole amount then due and payable on
such Securities and coupons for principal (and premium, if any) and interest,
with interest on any overdue principal (and premium, if any) and on any overdue
interest, to the extent that payment of such interest shall be legally
enforceable, 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, and
any other amounts due to the Trustee under Section 607.

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

     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series and any
related coupons 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 the
Support Agreement, or to enforce any other proper remedy.

SECTION 504.  Trustee May File Proofs of Claim.

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

                                      -39-
<PAGE>
 
whether the principal of the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Company or Industries for the payment of
overdue principal or interest) shall be entitled and empowered, by intervention
in such proceeding or otherwise:

          (i) to file and prove a claim for the whole amount of principal (and
     premium, if any) and interest owing and unpaid in respect of the Securities
     and to file such other papers or documents as may be necessary or advisable
     in order to have the claims of the Trustee (including any claim for the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel, and any other amounts due to the Trustee
     under Section 607) and of the Holders of Securities and coupons allowed in
     such judicial proceeding; and

          (ii) to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder of Securities and coupons to make such payments to the Trustee and,
in the event that the Trustee shall consent to the making of such payments
directly to the Holders of Securities and coupons, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 607.

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

SECTION 505.  Trustee May Enforce Claims Without Possession of Securities or
              Coupons.

     All rights of action and claims under this Indenture, the Support Agreement
or the Securities or coupons may be prosecuted and enforced by the Trustee
without the possession of any of the Securities or coupons or the production
thereof in any proceeding relating thereto, and any such proceeding instituted
by the Trustee shall be brought in its own name as trustee of an express trust,
and any recovery of judgment shall, after provision for the payment of the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, be for the ratable benefit of the Holders of the
Securities and coupons in respect of which such judgment has been recovered.

in case of the distribution of such money on account of principal (or premium,
if any) or interest, upon presentation of the Securities or coupons, as the case
may be, and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid:

          FIRST:  To the payment of all amounts due the Trustee under Section
     607;

     or priority of any kind, according to the amounts due and payable on such
     Securities and coupons for principal (and premium, if any) and interest,
     respectively; and

          THIRD:  To the Company or Industries, as the case may be.


SECTION 507.  Limitation on Suits.

     No Holder of any Security of any series or any related coupons shall have
any right to institute any proceeding, judicial or otherwise with respect to
this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

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

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

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

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

          (5) no direction inconsistent with such written request has been given

principal amount of the Outstanding Securities of that series;

<PAGE>
 
it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture or the Support Agreement to affect, disturb or prejudice the
rights of any other of such Holders or to obtain or to seek to obtain priority
or preference over any other of such Holders or to enforce any right under this
Indenture or the Support Agreement, except in the manner herein or therein
provided and for the equal and ratable benefit of all of such Holders.


SECTION 508.  Unconditional Right of Holders to Receive Principal, Premium
              and Interest.

     Notwithstanding any other provision in this Indenture, (1) the Holder of
any Security or coupon shall have the right, which is absolute and
unconditional, to receive payment of the principal of (and premium, if any) and
(subject to Section 307) interest on such Security or payment of such coupon on
the Stated Maturity or Maturities expressed in such Security or coupon (or, in
the case of redemption, on the Redemption Date) and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired or
affected without the consent of such Holder; and (2) the Holder of any Security
or coupon shall be considered a Lender (as defined in the Support Agreement) and
shall have all rights of a Lender set forth therein.


SECTION 509.  Restoration of Rights and Remedies.

every such case, subject to any determination in such proceeding, the Company,

mutilated, destroyed, lost or stolen Securities or coupons in the last paragraph
of Section 306, no right or remedy herein conferred upon or reserved to the

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

SECTION 511.  Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Security or
coupon to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to the Holders of Securities or coupons may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders of Securities or coupons, as the case may be.

SECTION 512.  Control by Holders of Securities.

     The Holders of a majority in principal amount of the Outstanding Securities
of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee, with respect to the Securities of
such series, provided that:

          (1) such direction shall not be in conflict with any rule of law or
     with this Indenture, expose the Trustee to personal liability or be unduly
     prejudicial to Holders not joined therein; and

          (2) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction.

SECTION 513.  Waiver of Past Defaults.

     The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series and any related coupons waive any past default
hereunder with respect to such series and its consequences, except a default:

          (1) in the payment of the principal of (or premium, if any) or
     interest on any Security of such series; or

          (2) in respect of a covenant or provision hereof which under Article
     Nine cannot be modified or amended without the consent of the Holder of
     each Outstanding Security of such series 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; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

SECTION 514.  Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security or
coupon by his acceptance thereof shall be deemed to have agreed, that any court
may in its discretion require, in any suit for the enforcement of any right or
remedy under this Indenture, or in any suit against the Trustee for any action
taken, suffered or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Securities of
any series, or to any suit instituted by any Holder of any Security or coupon
for the enforcement of the payment of the principal of (or premium, if any) or
interest on any Security or the payment of any coupon on or after the Stated
Maturity or Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).

SECTION 515.  Waiver of Stay or Extension Laws.

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

                                  ARTICLE SIX

                                  THE TRUSTEE

SECTION 601.  Certain Duties and Responsibilities.

     (a) Except during the continuance of an Event of Default with respect to
Securities of any series:

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

                                      -44-
<PAGE>
 
          (2) in the absence of bad faith on its part, the Trustee may, with
     respect to Securities of such series, conclusively rely, as to the truth of
     the statements and the correctness of the opinions expressed therein, upon
     certificates or opinions furnished to the Trustee and conforming to the
     requirements of this Indenture; but in the case of any such certificates or
     opinions 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 with respect to Securities of any series
has occurred and is continuing, the Trustee shall exercise, with respect to
Securities of such series, such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man 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 wilful 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;

          (3) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders of a majority in principal amount of the Outstanding
     Securities of any 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 with respect to the Securities of such series; and

          (4) 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.

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

SECTION 602.  Notice of Defaults.

     Within 90 days after the occurrence of any default hereunder with respect
to the Securities of any series, the Trustee shall transmit, in the manner and
to the extent provided in Section 313(c) of the Trust Indenture Act, notice of
all such defaults hereunder known to the Trustee, unless such default shall have
been cured or waived; provided, however, that, except in the case of a default
in the payment of the principal of (or premium, if any) or interest on any
Security of such series or in the payment of any sinking fund installment with
respect to Securities of such series, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or a trust committee of directors or Responsible Officers of the
Trustee in good faith determine that the withholding of such notice is in the
interest of the Holders of Securities of such series; and provided, further,
that in the case of any default of the character specified in Section 501(4)
with respect to Securities of such series, no such notice to Holders shall be
given until at least 30 days after the occurrence thereof.  For the purpose of

lapse of time would become, an Event of Default with respect to Securities of
such series.

SECTION 603.  Certain Rights of Trustee.

     Subject to Sections 315(a) through 315(d) of the Trust Indenture Act:

     suffering or omitting any action hereunder, the Trustee (unless other
     evidence be herein specifically prescribed) may, in the absence of bad
     faith on its part, rely upon an Officers' Certificate;

          (d) the Trustee may consult with counsel and the 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

     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders of Securities of any series pursuant to this

     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

     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, coupon, 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 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 or Industries, personally or by agent or attorney;
     and

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

SECTION 604.  Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities (except the Trustee's
certificates of authentication) and in any coupons shall be taken as the
statements of the Company, and the Trustee or any Authenticating Agent assumes
no responsibility for their correctness. The Trustee makes no representations as
to the validity or sufficiency of this Indenture, the Support Agreement or of
the Securities or coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder and that the statements made by it in a
Statement of Eligibility and Qualification on Form T-1 supplied to the Company
are true and accurate, subject to the qualifications set forth therein. The
Trustee or any Authenticating Agent shall not be accountable for the use or
application by the Company of Securities or the proceeds thereof.

SECTION 605.  May Hold Securities.

          The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and coupons and, subject
to Sections 310(b) and 311 of the Trust Indenture Act, may otherwise deal with
the Company, Industries or an Affiliate of either with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

SECTION 606.  Money Held in Trust.

     Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.

SECTION 607.  Compensation and Reimbursement.

     The Company and Industries agree:

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

          (2) except as otherwise expressly provided herein, to reimburse the
     Trustee upon its request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustee in accordance with any provision
     of this Indenture (including the reasonable compensation and the expenses
     and disbursements of its agents and counsel and any Authenticating Agent),
     except any such expense, disbursement or advance as may be attributable to
     its negligence, willful misconduct or bad faith; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without negligence, willful misconduct
     or bad faith on its part, arising out of or in connection with the
     acceptance or administration of the trust or trusts hereunder, including
     the costs and expenses of defending itself against any claim or liability
     in connection with the exercise or performance of any of its powers or
     duties hereunder.

     When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(5) or (6), the expenses and the
compensation for such services are intended to constitute expenses of
administration under any bankruptcy law.  As security for the performance of the
obligations of the Company and Industries under this Section the Trustee shall
have a lien prior to the Securities upon all property and funds held or
collected by the Trustee as such, except funds held in trust for the payment of
principal of, premium, if any, or interest, if any, on particular Securities.
The Company's obligations under this Section 607 and any lien arising hereunder
shall survive the resignation or removal of any Trustee, the discharge of the
Company's obligations pursuant to Article Four of this Indenture and/or the
termination of this Indenture. Nothing in Article Fourteen shall apply to the
right of the Trustee to receive any amounts due under or pursuant to this
Section 607.

SECTION 608.  Disqualification; Conflicting Interests.

     If the Trustee has or shall acquire a conflicting interest within the
meaning of Section 310(b) or any other provision of the Trust Indenture Act, the
Trustee shall either eliminate such interest or resign, to the extent and in the
manner provided by, and subject to the provisions of, the Trust Indenture Act
and this Indenture.

SECTION 609.  Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder that is a Corporation
organized and doing business under the laws of the United States of America, any
State or the District of Columbia, authorized under such laws to exercise
corporate trust powers, or any other person permitted by the Trust Indenture Act
to act as trustee under an indenture qualified under the Trust Indenture Act and
that has a combined capital and surplus (computed in accordance with Section
310(a)(2) of the Trust Indenture Act) of at least $50,000,000, is subject to
supervision or examination by Federal, State or District of Columbia authority
and is not otherwise ineligible under Section 310(a)(5) of the Trust Indenture
Act.  If such Corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of said supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such 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 hereinafter specified in this Article.

SECTION 610.  Resignation and Removal; Appointment of Successor.

     (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

     (b) The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company and
Industries.  If the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

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

     (d)  If at any time:

                                      -49-
<PAGE>
 
          (1) the Trustee shall fail to comply with Section 608 after written
     request by the Company and Industries or by any Holder of a Security who
     has been a bona fide Holder of a Security for at least six months; or

          (2) the Trustee shall cease to be eligible under Section 609 and shall
     fail to resign after written request therefor by the Company and Industries
     or by any such Holder; or

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

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

     (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company and Industries, by Board
Resolutions, shall promptly appoint a successor Trustee or Trustees 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 611.  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, Industries 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 611, become the successor Trustee with respect to the
Securities of such series and to that extent supersede the successor Trustee
appointed by the Company and Industries.  If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company and
Industries or the Holders of Securities and accepted appointment in the manner
required by Section 611, any Holder of a Security 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.

     (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor

                                      -50-
<PAGE>
 
Trustee with respect to the Securities of any series by mailing written notice
of such event by first-class mail, postage prepaid, to all Holders of Registered
Securities, if any, of such series as their names and addresses appear in the
Security Register and, if Securities of such Series are issuable as Bearer
Securities, by publishing notice of such event once in an Authorized Newspaper
in each Place of Payment located outside the United States.  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 611.  Acceptance of Appointment by Successor.

     (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company, Industries and to the retiring
Trustee an instrument accepting such appointment, and thereupon the resignation
or removal of the retiring Trustee shall become effective and such successor
Trustee, without any further act, deed or conveyance shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee; but, on the
request of the Company and Industries or on the request of the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder.

     (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company,
Industries, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates, (2) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees
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

                                     -51-
<PAGE>
 
such successor Trustee relates; but, on request of the Company and Industries or
on the request of 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, subject nevertheless to its lien
provided for in Section 607, 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 and Industries
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.

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

SECTION 612.  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 613.  Preferential Collection of Claims Against Company.

     If and when the Trustee shall be or become a creditor of the Company or
Industries (or any other obligor upon the Securities), the Trustee shall be
subject to the provisions of Section 311 and any other provision of the Trust
Indenture Act regarding the collection of claims against the Company or
Industries (or any such other obligor).

SECTION 614.  Appointment of Authenticating Agent.

     At any time when any of the Securities remain Outstanding the Trustee may
appoint an Authenticating Agent or Agents with respect to one or more series of
Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon exchange, registration of
transfer or partial redemption thereof or pursuant to Section 306, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder.  Wherever reference is made in this Indenture to the
authentication and

                                     -52-
<PAGE>
 
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 shall at all
times be a corporation organized and doing business under the laws of the United
States of America, any State thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having a combined capital and
surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture
Act) of not less than $50,000,000 and subject to supervision or examination by
Federal, State or District of Columbia authority.  If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published.  If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

     Any 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 the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall (i) mail written notice
of such appointment by first-class mail, postage prepaid, to all Holders of
Registered Securities, if any, of the series with respect to which such
Authenticating Agent will serve, as their names and addresses appear in the
Security Register, and (ii) if Securities of the series are issuable as Bearer

Terms.

     Neither the Company nor Industries shall consolidate with or merge into any
other Corporation or convey, transfer or lease its properties and assets
substantially as an entirety to any Person, unless:

          (1) the  Corporation formed by any such consolidation or into which it
     is merged or the Person which acquires by conveyance or transfer, or which
     leases, its properties and assets substantially as an entirety shall be a
     Corporation organized and existing under the laws of the United States of
     America, any State thereof or the District of Columbia and shall expressly
     assume, in the case of the Company, the due and punctual payment of the
     principal of (and premium, if any) and interest on all the Securities; in
     the case of the Company or Industries, the performance of every covenant of
     this Indenture on the part of the Company or Industries, as applicable; and
     in the case of Industries, all the obligations under the Support Agreement
     to be performed or observed;

                                     -56-

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

          (3) the Company or Industries, as applicable, has delivered to the
     Trustee an Officers' Certificate and an Opinion of Counsel, each stating
     that such consolidation, merger, conveyance, transfer or lease complies
     with this Section 801 and that all conditions precedent herein provided for
     relating to such transaction have been complied with.

SECTION 802.  Successor Corporation Substituted.

          Upon any consolidation by the Company or Industries with or merger by
     the Company or Industries into any other   Corporation or any conveyance,
     transfer or lease of either the Company's or Industries' properties and
     assets substantially as an entirety in accordance with Section 801, the
     successor  Corporation formed by such consolidation or into which it is
     merged or to which such conveyance, transfer or lease is made shall succeed
     to, and be substituted for, and may exercise every right and power of, the
     Company or Industries, as applicable, under this Indenture with the same
     effect as if such successor   Corporation had been named as the Company or
     Industries, as applicable, herein, and thereafter, except in the case of a
     lease, the predecessor  Corporation shall be relieved of all obligations
     and covenants under this Indenture, the Securities and, in the case of
     Industries, the Support Agreement.

every covenant of this Indenture on the part of the Company to be performed or
observed. Upon any such assumption, Industries or such Subsidiary shall succeed
to and be substituted for and may exercise every right and power of the Company
under this Indenture with the same effect as if Industries or such Subsidiary
had been named as the Company herein and the Company shall be released from its
liability as obligor on the Securities; provided that, in the case of such
assumption by a Subsidiary, the Support Agreement is modified so that references
to the Company and its Debt therein are changed to, or modified to include,
references to such Subsidiary and its Debt (including the Securities). No such
assumption shall be permitted unless Industries has delivered to the Trustee an
Officers' Certificate of Industries and an Opinion of Counsel for Industries,
each stating that such assumption and supplemental indenture comply with this
Article, that all conditions precedent herein provided for relating to such
transaction have been complied with and, in the event of assumption by a
Subsidiary, that Industries' obligations under this Indenture and the Support
Agreement (modified as aforesaid) remain in full force and effect.

SECTION 901.  Supplemental Indentures without Consent of Holders.

     Without the consent of any Holders of Securities or coupons, the
Company and Industries, when authorized by Board Resolutions, and the
Trustee, at any time and from time to time, may enter into one or more
indentures supplemental hereto, in form satisfactory to the Trustee, for
any of the following purposes:

     the Company or Industries, as the case may be, herein and in the Securities
     and coupons; or

          (2) to add to the covenants of the Company and Industries for the
     benefit of the Holders of all or any series of Securities (and if such
     covenants are to be for the benefit of less than all series of Securities,
     stating that such covenants are expressly being included solely for the
     benefit of such series) or to surrender any right or power herein conferred
     upon the Company or Industries; or

          (3) to add any additional Events of Default; or

          (4) to add to or change any of the provisions of this Indenture to
     provide that Bearer Securities may be registrable as to principal, to
     change or eliminate any restrictions on the payment of principal (or
     premium, if any) on Registered Securities or of principal (or premium, if
     any) or any interest on Bearer Securities, to permit Registered Securities
     to be exchanged for Bearer Securities or to permit the issuance of
     Securities in uncertificated form, provided any such action shall not
     adversely affect the interests of the Holders of Securities of any series
     or any related coupons in any material respect; or

          (5) to change or eliminate any of the provisions of this Indenture,
     provided that any such change or elimination shall become effective only
     when there is no Security Outstanding of any series created prior to the
     execution of such supplemental indenture which is entitled to the benefit
     of such provision; or

          (6) to establish the form or terms of Securities of any series and any
     related coupons as permitted by Sections 201 and 301; or

          (7) to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to the Securities of one or
     more series, to contain such provisions as shall be deemed necessary or
     desirable to confirm that all the

     to the Securities of any series as to which the predecessor Trustee is not

     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, pursuant to the requirements of Section 611(b); or

          (8) to cure any ambiguity, to correct or supplement any provision
     herein which may be defective or inconsistent with any other provision
     herein, or to make any other provisions with respect to matters or
     questions arising under this Indenture, provided such action shall not
     adversely affect the interests of the Holders of Securities of any series
     or any related coupons in any material respect; or

          (9) to effect assumption by Industries or a Subsidiary pursuant to
     Section 803; or

          (10) to conform this Indenture to any amendment of the Trust Indenture
     Act.

SECTION 902.  Supplemental Indentures with Consent of Holders.

     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company,
Industries and the Trustee, the Company and Industries, when authorized by Board
Resolutions, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or modifying
in any manner the rights of the Holders of Securities of such series and any
related coupons under this Indenture; provided, however, that no such
supplemental indenture shall, without the consent of the Holder of each
Outstanding Security or coupon affected thereby:

          (1) change the Stated Maturity of the principal of, or of any
     installment of principal of or interest on, any Security, or reduce the
     principal amount thereof or the rate of interest thereon or any premium
     payable upon the redemption thereof, or change the method of calculating
     the rate of interest thereon, or change any obligation of the Company to
     pay additional amounts pursuant to Section 1004 (except as contemplated by
     Section 801(1) and permitted by Section 901(1)), or reduce the amount of
     the principal of an Original Issue Discount Security that would be due and
     payable upon a declaration of acceleration of the Maturity thereof pursuant
     to Section 502, or change any Place of Payment in the United States where,
     or the coin or currency in which, any Security or any premium or the
     interest thereon is payable, 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) or modify
     the provisions of this Indenture with

                                     -59-
<PAGE>
 
     respect to the subordination of the Securities in a manner adverse to the
     Holders; or

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

     certain defaults hereunder and their consequences) provided for in this
     Indenture, or reduce the requirements of Section 1304 for quorum or voting;
     or

          (3) change any obligation of the Company to maintain an office or
     agency in each Place of Payment, or any obligation of the Company to
     maintain an office or agency outside the United States pursuant to Section
     1002; or

          (4) modify any of the provisions of this Section, Section 513 or
     Section 1010, except to increase any such percentage or to provide that
     certain other provisions of this Indenture cannot be modified or waived
     without the consent of the Holder of each Outstanding Security affected
     thereby; provided, however, that this clause shall not be deemed to require
     the consent of any Holder of a Security or coupon with respect to changes
     in the references to ``the Trustee'' and concomitant changes in this
     Section and Section 1009, or the deletion of this proviso, in accordance
     with the requirements of Sections 611(b) and 901(8).

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

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

     The Company and Industries shall have the right to set a record date for
the solicitation of any consents under this Article Nine, which record date
shall be set in accordance with Section 104.

SECTION 903.  Execution of Supplemental Indentures.

in relying upon, an Opinion of Counsel stating that the execution of such
supplemental indenture is authorized or permitted by this Indenture.

                                     -60-

The Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties, immunities or
liabilities under this Indenture or otherwise.


SECTION 904.  Effect of Supplemental Indentures.

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


SECTION 905.  Conformity with Trust Indenture Act.

     Every supplemental indenture executed pursuant to this Article shall

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

                                   COVENANTS


SECTION 1001.  Payment of Principal, Premium and Interest.

     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of that series in accordance with the
terms of the Securities, any coupons appertaining thereto and this Indenture.
Any interest due on Bearer Securities on or before Maturity, other than
additional amounts, if any, payable as provided in Section 1004 in respect of
principal of (or premium, if any, on) such a Security, shall be payable only
upon presentation and surrender of the several coupons for such interest
installments as are evidenced thereby as they severally mature.


                                      -61-

<PAGE>
 
SECTION 1002.  Maintenance of Office or Agency.

     The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series (but, except as
otherwise provided below, unless such Place of Payment is located outside the
United States, not Bearer Securities) may be presented or surrendered for
payment, where Securities of that series may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served.  The
Company initially hereby appoints the Trustee, its office or agency for each of
said purposes.  If Securities of a series are issuable as Bearer Securities, the
Company will maintain, subject to any laws or regulations applicable thereto, an
office or agency in a Place of Payment for such series which is located outside
the United States where Securities of such series and the related coupons may be
presented and surrendered for payment (including payment of any additional
amounts payable on Securities of such series pursuant  to Section 1004);
provided, however, that if the Securities of such series are listed on The Stock
Exchange of the United Kingdom and the Republic of Ireland or the Luxembourg
Stock Exchange or any other stock exchange located outside the United States and
such stock exchange shall so require, the Company will maintain a Paying Agent
in London or Luxembourg or any other required city located outside the United
States, as the case may be, so long as the Securities of such series are listed
on such exchange.  The Company will give prompt written notice to the Trustee of
the location, and any change in the location, of such office or agency.  If at
any time the Company shall fail to maintain any such required office or agency
in respect of any series of Securities or shall fail to furnish the Trustee with
the address thereof, such presentations and surrenders of Securities of that
series may be made and notices and demands may be made or served at the
Corporate Trust Office of the Trustee, except that Bearer Securities of that
series and the related coupons may be presented and surrendered for payment
(including payment of any additional amounts payable on Bearer Securities of
that series pursuant to Section 1004) at the place specified for the purpose
pursuant to Section 301 or, if no such place is specified, at the main office of
the Trustee in London, and the Company hereby appoints the Trustee as its agent
to receive such respective presentations, surrenders, notices and demands.

     No payment of principal, premium or interest on Bearer Securities shall be
made at any office or agency of the Company in the United States or by check
mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, payment
of principal of and any premium and interest in U.S. dollars (including
additional amounts payable in respect thereof) on any Bearer Security may be
made at the Corporate Trust Office of the Trustee in the Borough of Manhattan,
The City of New York if (but only if) payment of the full amount of such
principal, premium, interest or additional amounts at all offices outside the
United States maintained for the purpose by the Company in accordance with this
Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.


                                      -62-

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


SECTION 1003.  Money for Securities Payments to be Held in Trust.

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

     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, on or prior to each due date of the principal of (and
premium, if any) or interest on any Securities of that series, deposit with a
Paying Agent a sum sufficient to pay the principal (and premium, 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 (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.

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

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


                                      -63-

<PAGE>
 
     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 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
terms 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 sums.

     Any  sums deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium, if any)
or interest on any Security of any series and remaining unclaimed for two years
after such principal (and premium, if any) or interest has become due and
payable shall be paid to the Company on Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security or
any coupon appertaining thereto 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 an
Authorized Newspaper in each Place of Payment or mailed to each 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
or mailing, any unclaimed balance of such money then remaining will be repaid to
the Company.


SECTION 1004.  Additional Amounts.

     If the Securities of a series provide for the payment of additional
amounts, the Company will pay to the Holder of any Security of any series or any
coupon appertaining thereto additional amounts as provided therein.  Whenever in
this Indenture there is mentioned, in any context, the payment of principal of
(or premium, if any) or interest on, or in respect of, any Security of any
series or any related coupon or the net proceeds received on the sale or
exchange of any Security of any series, such mention shall be deemed to include
mention of the payment of additional amounts provided for in this Section to the
extent that, in such context, additional amounts are, were or would be payable
in respect thereof pursuant to the provisions of this Section and express
mention of the payment of additional amounts (if applicable) in any provisions
hereof shall not be construed as excluding additional amounts in those
provisions hereof where such express mention is not made.

     If the Securities of a series provide for the payment of additional
amounts, at least 10 days prior to the first Interest Payment Date with respect
to that series of Securities (or if the Securities of that series will not bear
interest prior to Maturity, the first day on which a payment of principal (and
premium, if any) is made), and at least 10 days prior to each date of payment of
principal (and premium, if any) or interest if there has been any change


                                      -64-

<PAGE>
 
with respect to the matters set forth in the below-mentioned Officers'
Certificate, the Company will furnish the Trustee and the Company's principal
Paying Agent or Paying Agents, if other than the Trustee, with an Officers'
Certificate instructing the Trustee and such Paying Agent or Paying Agents
whether such payment of principal of (and premium, if any) or interest on the
Securities of that series shall be made to Holders of Securities of that series
or the related coupons who are United States Aliens without withholding for or
on account of any tax, assessment or other governmental charge described in the
Securities of that series.  If any such withholding shall be required, then such
Officers' Certificate shall specify by country the amount, if any, required to
be withheld on such payments to such Holders of Securities or coupons and the
Company will pay to the Trustee or such Paying Agent the additional amounts
required by this Section.  The Company covenants to indemnify the Trustee and
any Paying Agent for, and to hold them harmless against, any loss, liability or
expense reasonably incurred without negligence or bad faith on their part
arising out of or in connection with actions taken or omitted by any of them in
reliance on any Officers' Certificate furnished pursuant to this Section.


SECTION 1005.  Corporate Existence.

     Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and its rights (charter and statutory) and franchises.

     Subject to Article Eight, (1) Industries will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and that of its subsidiary Northern Indiana and its rights (charter
and statutory) and franchises and those of Northern Indiana; provided, however,
that Industries shall not be required to preserve any such right or franchise of
Northern Indiana if, in the judgment of Industries, the preservation thereof is
no longer desirable in the conduct of the business of Northern Indiana and the
loss thereof would not be disadvantageous in any material respect to the Holders
of Securities, and (2) Industries will continue to own, directly or indirectly,
all of the outstanding common stock of Northern Indiana.


SECTION 1006.  Maintenance of Properties.

     Each of the Company and Industries will cause all properties used or useful
in the conduct of its business, and Industries will cause all properties used or
useful in the business of the Subsidiaries, to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this Section shall
prevent Industries from discontinuing the operation or maintenance of any of
such properties or disposing of them if such discontinuance or disposal is, in
the judgment of Industries, desirable in the


                                      -65-

<PAGE>
 
conduct of its business or the business of the Subsidiaries and not
disadvantageous in any material respect to the Holders of Securities.


SECTION 1007.  Payment of Taxes and Other Claims.

     Each of the Company and Industries will pay or discharge or cause to be
paid or discharged, before the same shall become delinquent, (1) all taxes,
assessments and governmental charges levied or imposed upon it and, in the case
of Industries, any of the Subsidiaries, or upon the income, profits or property
of the Company, Industries or any of the Subsidiaries, and (2) all lawful claims
for labor, materials and supplies which, if unpaid, might by law become a lien
upon the property of the Company, Industries or any of the Subsidiaries;
provided, however, that none of the Company, Industries or any of the
Subsidiaries shall be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings.


SECTION 1008.   Limitations on Dividends, Repurchases and Sinking Fund Payments.

     If there shall have occurred any event that would, with the giving of
notice or the passage of time, or both, constitute an Event of Default under the
Indenture or the Company shall have given notice of its election to extend an
interest payment period of a series of the Securities as provided in the Board
Resolution or indenture supplemental hereto providing for the issuance of such
series of the Securities and such period, or any extension thereof, shall be
continuing, the Company shall not, until such Event of Default shall have been
cured or waived in accordance with this Indenture or shall have ceased to exist
and all interest accrued on such series of the Securities during an extended
interest payment period shall have been paid in full, (i) declare, set aside or
pay any dividend or distribution on any shares of any class or series of its
capital stock, except for dividends or distributions in shares of its capital
stock or in rights to acquire shares of its capital stock, (ii) repurchase,
redeem or otherwise acquire, or make any sinking fund payment for the purchase
or redemption of, any shares of any class or series of its capital stock (except
by conversion into or exchange for shares of its capital stock), (iii) make any
liquidation payment with respect to any shares of any class or series of its
capital stock, (iv) make any payment of interest, principal or premium, if any,
on or repay, repurchase, redeem or otherwise acquire or make any sinking fund
payment for the purchase or redemption of any debt securities issued by the
Company that rank pari passu with or junior to the Securities, or (v) make any
guarantee payment with respect to any of the foregoing.


SECTION 1009.  Statement by Officers as to Default.

     (a) Each of the Company and Industries will deliver to the Trustee, within
120 days after the end of each fiscal year of the Company ending after the date
hereof, a certificate, signed by the principal executive officer, principal
financial officer or principal accounting officer of the Company or Industries,
as the case may be, stating whether or not


                                      -66-

<PAGE>
 
to the best knowledge of the signers thereof the Company or Industries, as the
case may be, is in default in the performance and observance of any of the
terms, provisions and conditions of this Indenture (without regard to any period
of grace or requirement of notice provided hereunder) and, if the Company or
Industries shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge.

     (b) The Company or Industries, as applicable, will deliver to the Trustee,
within five days after the occurrence thereof, written notice of any event which
after notice or lapse of time would become an Event of Default pursuant to
clause (4)  of Section 501.


SECTION 1010.  Waiver of Certain Covenants.

     The Company and Industries may omit in any particular instance to comply
with any term, provision or condition set forth in Sections 1006 and 1007 with
respect to the Securities of any series if before the time for such compliance
the Holders of at least a majority in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such term,
provision or condition, but no such waiver shall extend to or affect such term,
provision or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company and Industries and
the duties of the Trustee in respect of any such term, provision or condition
shall remain in full force and effect.


SECTION 1011.  Support Agreement.

     Each of the Company and Industries covenants and agrees for the benefit of
each series of Securities that (1) it will perform its respective obligations
under the Support Agreement, and (2) it will not agree to any amendment or
termination of the Support Agreement as in effect on the date of this Indenture,
except in accordance with the terms of the Support Agreement as in effect on the
date of this Indenture.

                            REDEMPTION OF SECURITIES


SECTION 1101.  Applicability of Article.

     Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 301 for Securities of any series) in
accordance with this Article.


                                      -67-

<PAGE>
 
SECTION 1102.  Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution.  In case of any redemption at the election of the Company of
the Securities of any series, with the same issue date, interest rate, Stated
Maturity and other terms, the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee in writing of such Redemption
Date and of the principal amount of Securities of such series to be redeemed.
In the case of any redemption of Securities (i) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, or (ii) pursuant to an election of the Company
which is subject to a condition specified in the terms of such Securities, the
Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction or condition.


SECTION 1103.  Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee from the Outstanding Securities of
such series (other than Securities of such series held by the Company), not
previously called for redemption by such method as the Trustee shall deem fair
and appropriate and which may provide for the selection for redemption of
portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Registered
Securities of such series of a denomination larger than the minimum authorized
denomination for Securities of that series.  Unless otherwise provided in the
Securities of a series, partial redemptions must be in an amount not less than
$1,000,000 principal amount of Securities.

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

     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.


SECTION 1104.  Notice of Redemption.

     Notice of redemption shall be given in the manner provided in Section 106
to the Holders of Securities to be redeemed not less than 30 nor more than 60
days prior to the Redemption Date.

     All notices of redemption shall state:


                                      -68-

<PAGE>
 
          (1)  the Redemption Date,

          (2)  the Redemption Price,

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

          (4)  that on the Redemption Date the Redemption Price will become due
     and payable upon each such Security to be redeemed and, if applicable, that
     interest thereon will cease to accrue on and after said date,

          (5)  the place or places where such Securities, together in the case
     of Bearer Securities with all coupons appertaining thereto, if any,
     maturing after the Redemption Date, are to be surrendered for payment of
     the Redemption Price, and

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

With respect to any notice of redemption of Securities at the election of the
Company, unless, upon the giving of such notice, such Securities shall be deemed
to have been paid in accordance with Section 401, such notice may state that
such redemption shall be conditional upon the receipt by the Trustee, on or
prior to the date fixed for such redemption, of money sufficient to pay the
principal of and premium, if any, and interest, if any, on such Securities and
that if such money shall not have been so received such notice shall be of no
force or effect and the Company shall not be required to redeem such Securities.
In the event that such notice of redemption contains such a condition and such
money is not so received, the redemption shall not be made and within a
reasonable time thereafter notice shall be given, in the manner in which the
notice of redemption was given, that such money was not so received and such
redemption was not required to be made.  A notice of redemption published as
contemplated by Section 106 need not identify particular Registered Securities
to be redeemed.

     Notice of redemption of Securities to be redeemed at the election of the
Company, and any notice of non-satisfaction of a condition for redemption as
aforesaid, shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.


SECTION 1105.  Deposit of Redemption Price.

     On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest, if any, on, all the
Securities which are to be redeemed on that date.


                                      -69-

<PAGE>
 
SECTION 1106.  Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, and the conditions, if
any, set forth in such notice having been satisfied, the Securities so to be
redeemed shall, on the Redemption Date, become due and payable at the Redemption
Price therein specified, and from and after such date (unless, in the case of an
unconditional notice of redemption, the Company shall default in the payment of
the Redemption Price and accrued interest) such Securities shall cease to bear
interest and the coupons for such interest appertaining to any Bearer Securities
so to be redeemed, except to the extent provided below, shall be void.  Upon
surrender of any such Security for redemption in accordance with said notice,
together with all coupons, if any, appertaining thereto maturing after the
Redemption Date, such Security shall be paid by the Company at the Redemption
Price, together with accrued interest, if any, to the Redemption Date; provided,
however, that installments of interest on Bearer Securities whose Stated
Maturity is on or prior to the Redemption Date shall be payable only upon
presentation and surrender of coupons for such interest (at an office or agency
located outside the United States except as otherwise provided in Section 1002);
and provided, further, that installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.

     If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing coupons, or the surrender of such missing coupon or
coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless.  If thereafter the Holder of such Security shall
surrender to the Trustee or any Paying Agent any such missing coupon in respect
of which a deduction shall have been made from the Redemption Price, such Holder
shall be entitled to receive the amount so deducted; provided, however, that
interest represented by coupons shall be payable only upon presentation and
surrender of those coupons at an office or agency located outside of the United
States except as otherwise provided in Section 1002.

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


SECTION 1107.  Securities Redeemed in Part.

     Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires with
respect to any Registered Security, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his


                                     -70-

<PAGE>
 
attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of the same series, Stated Maturity
and of any authorized denomination as requested by such holder, in aggregate
principal amount equal to and in exchange for the unredeemed portion of the
principal of the Security so surrendered.

     Except as otherwise specified as contemplated by Section 301, if a Global
Security is so surrendered, the Company shall execute, and the Trustee shall
authenticate and deliver to the Depositary in global form, without service
charge, a new Global Security in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Global Security so surrendered.



                                 ARTICLE TWELVE

                                 SINKING FUNDS


SECTION 1201.  Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

     The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment." If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 1202.  Each sinking fund payment shall be applied to the redemption
of Securities of any series as provided for by the terms of Securities of such
series.


SECTION 1202.  Satisfaction of Sinking Fund Payments with Securities.

     The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption), together in the case of any Bearer
Securities of such series with all unmatured coupons appertaining thereto, and
(2) may apply as a credit Securities of a series which have been redeemed either
at the election of the Company pursuant to the terms of such Securities or
through the application of permitted optional sinking fund payments pursuant to
the terms of such Securities, in each case in satisfaction of all or any part of
any sinking fund payment with respect to the Securities of such series required
to be made pursuant to the terms of such Securities as provided for by the terms
of such series; provided that such Securities have not been previously so
credited.  Such Securities shall be received and credited for such purpose by
the Trustee at the Redemption


                                      -71-

<PAGE>
 
Price specified in such Securities for redemption through operation of the
sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.


SECTION 1203.  Redemption of Securities for Sinking Fund.

     Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202 and stating the basis for such credit and that such
Securities have not previously been so credited and will also deliver to the
Trustee any Securities to be so delivered.  Not less than 30 days before each
such sinking fund payment date the Trustee shall select the Securities to be
redeemed upon such sinking fund payment date in the manner specified in Section
1103 and cause notice of the redemption thereof to be given in the name of and
at the expense of the Company in the manner provided in Section 1104.  Such
notice having been duly given, the redemption of such Securities shall be made
upon the terms and in the manner stated in Sections 1106 and 1107.

reasonable detail the action proposed to be taken at the meeting, and the

In any other case the meeting may be adjourned for a period of not less than 10

notice, consent, waiver or other action which this Indenture


                                      -73-

<PAGE>
 
expressly provides may be made, given or taken by the Holders of a specified

Outstanding Securities of a series may be adopted at a meeting or an adjourned
meeting duly reconvened and at which a quorum is present as aforesaid by the
affirmative vote of the Holders of such specified percentage in principal amount
of the Outstanding Securities of that series.

     Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the related coupons,
whether or not present or represented at the meeting.


SECTION 1305.  Determination of Voting Rights; Conduct and Adjournment of
Meetings.

     (a)  Notwithstanding any other provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of such series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner specified in Section 104 and the
appointment of any proxy shall be proved in the manner specified in Section 104.
Such regulations may provide that written instruments appointing proxies,
regular on their face, may be presumed valid and genuine without the proof
specified in Section 104 or other proof.

     (b)  The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 1302(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman.  A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

     (c)  At any meeting each Holder of a Security of such series or proxy shall
be entitled to one vote for each $100 principal amount of Securities of such
series held or represented by him; provided, however, that no vote shall be cast
or counted at any meeting in respect of any Security challenged as not
Outstanding and ruled by the chairman of the meeting to be not Outstanding.  The
chairman of the meeting shall have no right to vote, except as a Holder of a
Security of such series or proxy.

their representatives by proxy and the principal amounts and serial numbers of

permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in triplicate of all votes cast at the meeting.  A record, at least in
triplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and

this Article, any request, demand, authorization, direction, notice, consent,
waiver or other action may be made, given or taken by Holders by written

                                ARTICLE FOURTEEN

                          SUBORDINATION OF SECURITIES


SECTION 1401.  Securities Subordinated to Senior Indebtedness.

     The Company covenants and agrees, and each Holder of Securities issued
hereunder, by his acceptance thereof, likewise covenants and agrees, and for
purposes of Section 508 consents, that all Securities shall be issued subject to
the provisions of this Article Fourteen, and each Holder of a Security, whether
upon original issue or upon transfer or assignment thereof, accepts and agrees
to be bound by such provisions.  The payment of the principal of and premium, if
any, and interest on all Securities issued hereunder shall, to the extent and in
the manner hereinafter set forth, be subordinated and  junior in right of
payment to the prior payment in full of all Senior Indebtedness, whether


                                      -75-

<PAGE>
 
outstanding at the date of this Indenture or thereafter incurred.  No provision
of this Article Fourteen shall prevent the occurrence of any default or Event of
Default hereunder.


SECTION 1402.  Payment Over of Proceeds Upon Default on Senior Indebtedness.

     In the event and during the continuation of any default in the payment
of principal, premium, interest or any other payment due on any Senior
Indebtedness continuing beyond the period of grace, if any, specified in the
instrument evidencing such Senior Indebtedness, unless and until such default
shall have been cured or waived or shall have ceased to exist, and in the event
that the maturity of any Senior Indebtedness has been accelerated because of a
default, unless and until such acceleration shall have been revoked in
accordance with the instrument evidencing such Senior Indebtedness or such
Senior Indebtedness shall have been paid in full, then no payment shall be made
by the Company with respect to the principal (including redemption and sinking
fund payments) of, or premium, if any, or interest on the Securities.

     In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee when such payment is prohibited by the preceding
paragraph of this Section 1402, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that the holders of Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee within 90 days of such payment
of the amounts then due and owing on Senior Indebtedness, and only the amounts
specified in such notice to the Trustee shall be paid to the holders of Senior
Indebtedness.


SECTION 1403.  Payment Over of Proceeds Upon Dissolution; Bankruptcy;
               Liquidation.

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


                                      -76-

<PAGE>
 
Company) or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing any
Senior Indebtedness may have been issued, as their respective interests may
appear, to the extent necessary to pay all Senior Indebtedness in full, in money
or money's worth, after giving effect to any concurrent payment or distribution
to or for the holders of Senior Indebtedness, before any payment or distribution
is made to the Holders of Securities or to the Trustee.

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

     For purposes of this Article Fourteen, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other Corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article Fourteen with
respect to the Securities to the payment of all Senior Indebtedness which may at
the time be outstanding; provided that (i) such Senior Indebtedness is assumed
by the new Corporation, if any, resulting from such reorganization or
readjustment, and (ii) the rights of the holders of the Senior Indebtedness are
not, without the consent of such holders, altered by such reorganization or
readjustment.  The consolidation of the Company with, or the merger of the
Company into, another Corporation or the liquidation or dissolution of the
Company following the conveyance or transfer of its property as an entirety, or
substantially as an entirety, to another Corporation upon the terms and
conditions provided for in Article Eight hereof shall not be deemed a
dissolution, winding-up, liquidation or reorganization for the purposes of this
Section 1403 if such other Corporation shall, as part of such consolidation,
merger, conveyance or transfer, comply with the conditions stated in Article
Eight hereof. Nothing in Article Fourteen shall apply to the right of the
Trustee to receive any amounts due under or pursuant to Section 607.


SECTION 1404.  Subrogation.

     Subject to the payment in full of all Senior Indebtedness, the rights
of the Holders of the Securities shall be subrogated to the rights of the
holders of Senior Indebtedness to receive payments or distributions of cash,
property or securities of the


                                      -77-

<PAGE>
 
Company applicable to the Senior Indebtedness until the principal of (and
premium, if any) and interest on the Securities shall be paid in full; and, for
purposes of such subrogation, no payments or distributions to the holders of
such Senior Indebtedness of any cash, property or securities to which the
Holders of the Securities or the Trustee would be entitled except for the
provisions of this Article Fourteen, and no payment over pursuant to the
provisions of this Article Fourteen, to or for the benefit of the holders of
such Senior Indebtedness by Holders of the Securities or the Trustee, shall, as
between the Company, its creditors other than holders of Senior Indebtedness,
and the Holders of the Securities, be deemed to be a payment by the Company to
or on account of the Senior Indebtedness. It is understood that the provisions
of this Article Fourteen are and are intended solely for the purposes of
defining the relative rights of the Holders of the Securities, on the one hand,
and the holders of the Senior Indebtedness, on the other hand.

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

     Upon any payment or distribution of assets of the Company referred to in
this Article Fourteen, the Trustee, subject to the provisions of Section 601,
and the Holders of the Securities shall be entitled to rely upon any order or
decree made by any court of competent jurisdiction in which any such
dissolution, winding-up, liquidation or reorganization proceedings are pending
or a certificate of the receiver, trustee in bankruptcy, liquidation trustee,
agent or other person making such payment or distribution, delivered to the
Trustee or to the Holders of the Securities, for the purposes of ascertaining
the persons entitled to participate in such distribution, the holders of the
Senior Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article Fourteen.


SECTION 1405.  Trustee to Effectuate Subordination.

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


                                      -78-

<PAGE>
 
SECTION 1406.  Notice to the Trustee.
 
     The Company shall give prompt written notice to a Responsible Officer
of the Trustee at the Corporate Trust Office of any fact known to the Company
which would prohibit the making of any payment of monies to or by the Trustee or
Paying Agent in respect of the Securities pursuant to the provisions of this
Article Fourteen.  Notwithstanding the provisions of this Article Fourteen or
any other provision of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts which would prohibit the making of any
payment of monies to or by the Trustee or Paying Agent in respect of the
Securities pursuant to the provisions of this Article Fourteen, unless and until
a Responsible Officer of the Trustee shall have received written notice thereof
at the Corporate Trust Office from the Company or a holder or holders of Senior
Indebtedness or from any trustee therefor; and before the receipt of any such
written notice, the Trustee, subject to the provisions of Section 601, shall be
entitled in all respects to assume that no such facts exist; provided, however,
that if the Trustee shall not have received the notice provided for in this
Section 1406 at least three Business Days prior to the date upon which by the
terms hereof any money may become payable for any purpose (including, without
limitation, the payment of the principal of (or premium, if any) or interest on
any Security), then, anything herein contained to the contrary notwithstanding,
the Trustee shall have full power and authority to receive such money and to
apply the same to the purposes for which they were received, and shall not be
affected by any notice to the contrary which may be received by it within three
Business Days prior to such date.

     The Trustee, subject to the provisions of Section 601, shall be entitled to
rely on the delivery to it of a written notice by a Person representing himself
to be the holder of Senior Indebtedness (or a trustee on behalf of such holder)
to establish that such notice has been given by a holder of Senior Indebtedness
or a trustee on behalf of any such holder or holders.  In the event that the
Trustee determines in good faith that further evidence is required with respect
to the right of any Person as a holder of Senior Indebtedness to participate in
any payment or distribution pursuant to this Article Fourteen, the Trustee may
request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of Senior Indebtedness held by such Person, the extent
to which such Person is entitled to participate in such payment or distribution
and any other facts pertinent to the rights of such Person under this Article
Fourteen, and if such evidence is not furnished, the Trustee may defer any
payment to such Person pending judicial determination as to the right of such
Person to receive such payment.


SECTION 1407.  Rights of Trustee as Holder of Senior Indebtedness.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article Fourteen with respect to any Senior Indebtedness at
the time held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.


                                      -79-

<PAGE>
 
SECTION 1408.  Trustee Not Fiduciary for Holders of Senior Indebtedness.

     With respect to the holders of Senior Indebtedness of the Company, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article Fourteen, and no
implied covenants or obligations with respect to the holders of such Senior
Indebtedness shall be read into this Indenture against the Trustee.  The Trustee
shall not be deemed to owe any fiduciary duty to the holders of such Senior
Indebtedness, and, subject to the provisions of Section 601, the Trustee shall
not be liable to any holder of such Senior Indebtedness if it shall pay over or
deliver to the Holders of the Securities, the Company or any other Person money
or assets to which any holder of the Senior Indebtedness shall be entitled by
virtue of this Article Fourteen or otherwise.


SECTION 1409.  Rights of Holders of Senior Indebtedness Not Impaired.

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

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


SECTION 1410.  Effect of Satisfaction and Discharge of the Indenture.

     Notwithstanding any other provision of this Indenture, upon the execution
and delivery by the Trustee to the Company of instruments acknowledging
satisfaction and discharge of the Indenture with respect to one or more series
of Securities in accordance with Section 401, any funds deposited with the
Trustee in trust pursuant to paragraph (1)(B) of Section 401 shall cease to be
subject to the provisions of this Article Fourteen.

               IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS,
                            DIRECTORS AND EMPLOYEES


SECTION  1501.  Liability Solely Corporate.

     No recourse shall be had for the payment of the principal of or premium, if
any, or interest, if any, on any Securities, or any part thereof, or for any
claim based thereon or otherwise in respect thereof, or of the indebtedness
represented thereby, or upon any obligation, covenant or agreement under this
Indenture, against any incorporator, stockholder, officer, director or employee,
as such, past, present or future of the Company or Industries or of any
predecessor or successor   Corporation (either directly or through the Company,
Industries or a predecessor or successor  Corporation of either of them),
whether by virtue of any constitutional provision, statute or rule of law, or by
the enforcement of any assessment or penalty or otherwise; it being expressly
agreed and understood that this Indenture and all the Securities are solely
corporate obligations, and that no personal liability whatsoever shall attach
to, or be incurred by, any incorporator, stockholder, officer, director or
employee, past, present or future, of the Company or Industries or of any
predecessor or successor  Corporation of either of them, either directly or
indirectly through the Company, Industries or any predecessor or successor
Corporation of either of them, because of the indebtedness hereby authorized or
under or by reason of any of the obligations, covenants or agreements contained
in this Indenture or in any of the Securities or to be implied herefrom or
therefrom, and that any such personal liability is hereby expressly waived and
released as a condition of, and as part of the consideration for, the execution
of this Indenture and the issuance of the Securities; provided, however, that
nothing in this Section  1501 shall be interpreted to relieve Industries of its
corporate obligations set forth in this Indenture by virtue of it being a
stockholder of the Company.

                                    FORM OF
                     RESOLUTIONS OF THE BOARD OF DIRECTORS
                        OF NIPSCO CAPITAL MARKETS, INC.

     The undersigned, being all of the directors of NIPSCO Capital Markets,
Inc., an Indiana corporation ("Capital"), in lieu of holding a special meeting
of the Board of Directors of Capital, hereby adopt the following resolutions by
unanimous written consent pursuant to Section 23-1-34-2 of the Indiana Business
Corporation Law.

     WHEREAS, the Board of Directors of Capital has previously authorized the
filing of a Registration Statement with the Securities and Exchange Commission,
jointly with NIPSCO Industries, Inc. ("Industries"), to register the offering
and sale of Capital's unsecured subordinated debt securities in an aggregate
principal amount of up to $75,000,000 and Industries' obligations pursuant to
the Support Agreement, dated as of April 4, 1989, as amended, between Industries
and Capital; and

     WHEREAS, the Board of Directors of Capital has authorized the execution and
delivery, by and on behalf of Capital, of an Indenture among Capital,
Industries, and Chemical Bank, as trustee (the "Trustee"), providing for the
issuance from time to time of Capital's subordinated debt securities; and

     WHEREAS, Capital and Industries have filed with the Securities and Exchange
Commission a Registration Statement on Form S-3, Registration No. 33-______ (the
"Registration Statement"), registering the offer and sale of such subordinated
debt securities; and

     WHEREAS, the Board of Directors desires to establish, pursuant to Section
301 of the Indenture, a series of subordinated debt securities to be issued
pursuant to the Indenture and offered and sold under the Registration Statement;

     NOW THEREFORE BE IT RESOLVED by the Board of Directors as follows:

     1.  Capital hereby establishes, pursuant to Section 301 of the Indenture, a
series of subordinated debt securities as follows (capitalized terms not defined
in these resolutions having the meaning given to them in the Indenture):

     (a) Such subordinated debt securities shall be designated the "Junior
Subordinated Deferrable Interest Debentures, Series A" (the "Series A
Debentures").

     (b) The aggregate principal amount at maturity of the Series A Debentures
that may be authenticated and delivered under the Indenture (except for Series A
Debentures that may be authenticated and delivered upon registration of transfer
of, or in exchange for, or in lieu of, other Series A Debentures pursuant to
Sections 304, 305, 306, 906 or 1107 of the Indenture) shall not be in excess of
$75,000,000.

     (c) The Series A Debentures shall mature thirty years from the date of
issuance or from such other date reasonably before or after the date of issuance
(the "Issue Date") as may be approved by the Treasurer of Capital at the time of
pricing of the Series A Debentures, such
<PAGE>
 
approval to be conclusively evidenced by the delivery of a Company Order to the
Trustee pursuant to Section 303 of the Indenture reflecting such Issue Date.

     (d) Each Series A Debenture shall bear interest at a rate per annum to be
approved by the Treasurer of Capital at the time of the pricing of the Series A
Debentures, such approval to be conclusively evidenced by the delivery of a
Company Order to the Trustee pursuant to Section 303 of the Indenture reflecting
such interest rate (the "Interest Rate"). Each Series A Debenture shall bear
interest on the unpaid principal of such Series A Debenture from the Issue Date
until such principal becomes due and payable and on any overdue principal and
(to the extent that payment of such interest is enforceable under applicable
law) on any overdue installment of interest at the Interest Rate, compounded
quarterly.  Subject to the provisions of paragraph (f), below, interest shall be
payable quarterly in arrears on March 31, June 30, September 30, and December 31
of each year (each, an "Interest Payment Date"), commencing March 31, 1996, to
the person in whose name such Series A Debenture is registered on the Regular
Record Date for such Interest Payment Date.  The Regular Record Date for Series
A Debentures issued in the form of one or more Global Securities shall be the
close of business on the Business Day next preceding an Interest Payment Date;
provided, however, that if the Series A Debentures are no longer represented by
one or more Global Securities, the Company may select a Regular Record Date for
each payment of interest which shall be any date at least one Business Day
before an Interest Payment Date.

     (e) The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months.  Except as provided in the
following sentence, the amount of interest payable for any period shorter than a
full quarterly period for which interest is computed will be computed on the
basis of the actual number of days elapsed in such 30-day month.  In the event
that any date on which interest is payable on the Series A Debentures is not a
Business Day, then payment of the interest payable on such date will be made on
the next succeeding day that is a Business Day (and without any interest or
other payment in respect of such delay), except that, if such Business Day is in
the next succeeding calendar year, then such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on such date.

     (f) Capital shall have the right at any time, and from time to time, during
the term of the Series A Debentures, so long as an Event of Default has not
occurred and is not continuing, to defer payments of interest on the Series A
Debentures by extending the interest payment period for a period not exceeding
20 consecutive quarters (the "Extended Interest Payment Period").  At the end of
such Extended Interest Payment Period, Capital shall pay all interest then
accrued and unpaid (together with interest thereon, compounded quarterly at the
Interest Rate, to the extent permitted by applicable law) to the Holders of the
Series A Debentures in whose names the Series A Debentures are registered in the
Security Register on the first Regular Record Date after the end of the Extended
Interest Payment Period.  Prior to the termination of any such Extended Interest
Payment Period, Capital may further extend such period, provided that such
Extended Interest Payment Period, together with all such previous and further
extensions thereof, shall not exceed 20 consecutive quarters or extend beyond
the maturity of the Series A Debentures.  Upon the termination of any Extended
Interest Payment Period and the payment of all accrued and unpaid interest then
due, Capital may commence a new Extended Interest Payment Period, subject to the
terms set forth in the Indenture and this paragraph.  No interest shall be due

with respect to a Series A Debenture redeemed by Capital pursuant to paragraph
(i), below.

     (g) Capital shall give the Trustee and the Holders of the Series A
Debentures notice of its selection of an Extended Interest Payment Period ten
Business Days prior to the earlier of (i) the next Interest Payment Date or (ii)
the date upon which Capital is required to give notice to the Holders of the
Series A Debentures (or, if applicable, to the New York Stock Exchange or other
applicable self-regulatory organization) of the record or payment date of such
related interest payment. The quarter in which any notice is given pursuant to
this paragraph shall be counted as one of the 20 quarters permitted in the
maximum Extended Interest Payment Period.

     (h) The principal of each Series A Debenture and premium, if any, and
interest thereon shall be payable at the office of the Paying Agent, in the
Borough of Manhattan, The City of New York.  Chemical Bank shall initially be
appointed as Paying Agent.

     (i) Capital shall have the right to redeem the Series A Debentures, in
whole or in part, from time to time, on or after __________, 2006, upon not less
than 30 nor more than 60 days' notice, at a redemption price or redemption
prices equal to such percentage or percentages of the principal amount of the
Series A Debentures as may be approved by the Treasurer of Capital at the time
of the pricing of the Series A Debentures, such approval to be conclusively
evidenced by the delivery of a Company Order to the Trustee pursuant to Section
303 of the Indenture reflecting such redemption price or redemption prices.  If
less than all of the Series A Debentures are to be redeemed, the particular
Series A Debentures to be redeemed shall be selected, not more than 60 days
prior to the redemption date, pro rata or by lot or by any other method that the
Trustee shall deem fair and appropriate; provided, however, that if at the time
of redemption, the Series A Debentures are registered as a Global Security, the
Depositary shall determine by lot the principal amount of such Series A
Debentures held by each Holder to be redeemed.

     (j) Capital shall have no obligation to redeem or purchase the Series A
Debentures pursuant to any sinking fund or analogous provisions or at the option
of a Holder thereof.

     (k) The Series A Debentures shall be issued in the form of one or more
Global Securities, which will have an aggregate principal amount equal to that
of the Series A Debentures, and shall be deposited with, or on behalf of, The
Depository Trust Company, as Depositary.  A Global Security shall be
exchangeable for Series A Debentures registered in the names of persons other
than the Depositary or its nominee only under the circumstances described in
Section 305 of the Indenture.  Any Series A Debenture issued in certificated
form pursuant to Section 305 of the Indenture shall be in denominations of
$1,000 or any integral multiple thereof.

     (l) No payments of additional amounts in respect of taxes or similar
charges withheld or deducted from the Series A Debentures will be made to any
United States Alien pursuant to Section 301(16) of the Indenture.

     (m) The Series A Debentures shall contain such other terms, conditions and
provisions not provided for in these or prior resolutions of the Board of
Directors as the Treasurer of Capital may approve, such approval to be
conclusively evidenced by the delivery to the Trustee of a Company Order
specifying such terms, conditions and provisions pursuant to Section 303 of the
Indenture.

     2.  The form of debenture for the Series A Debentures, in substantially the
form included in the Registration Statement, and the terms and conditions set
forth therein are hereby approved and authorized in all respects, with such
changes therein as the officer executing such Series A Debentures shall
determine, and such Series A Debentures shall be executed for and on behalf of
Capital by any one of the Chairman of the Board, the President, any Vice
President, or the Treasurer, and attested to by the Secretary or any Assistant
Secretary, either by original or facsimile signature.

     3.  Within the limitations specified in these resolutions, the Chairman of

hereby authorized to deliver to the Trustee an Officers' Certificate
establishing the Series A Debentures provided for herein and all other terms
specified by Section 301 of the Indenture and to issue one or more Company
Orders, determining therein all terms and provisions of the Series A Debentures
as provided for in these resolutions and the Officers' Certificate.

     4.  Subject to the Registration Statement having been declared effective
and to the continuance of such effectiveness in full force and effect, the
Chairman, the President, any Vice President and the Treasurer of Capital are
hereby authorized to issue and sell the Series A Debentures on terms and
conditions consistent with these resolutions, the Indenture and the Registration
Statement.

     5.   The officers of Capital are hereby authorized, directed and empowered
to do and perform and to cause to be done and performed all acts and things, and
to execute and file such documents and instruments as may be necessary,
convenient or appropriate and to pay all such charges and expenses as may be

       ____% JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURE, SERIES A
                               DUE _______, 2026

NIPSCO Capital Markets, Inc, an Indiana corporation (the "Company", which term
includes any successor corporation under the Indenture hereinafter referred to),
for value received, hereby promises to pay to ___________________________, or
registered assigns, the principal sum of ______________ Dollars on _________,
2026, and to pay interest on said principal sum from ___________, 1996, or from
the most recent interest payment date (each such date, an "Interest Payment
Date") to which interest has been paid or duly provided for, quarterly (subject
to deferral as set forth herein) in arrears on March 31, June 30, September 30
and December 31 of each year commencing March 31, 1996, at the rate of _____%
per annum until the principal hereof shall have become due and payable, and on
any overdue principal and premium, if any, and (without duplication and to the
extent that payment of such interest is enforceable under applicable law) on any
overdue installment of interest at the same rate per annum compounded quarterly.
The amount of interest payable on any Interest Payment Date shall be computed on
the basis of a 360-day year of twelve 30-day months.  In the event that any date
on which interest is payable on this Debenture is not a Business Day, then
payment of interest payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay), except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business
Day, in each case with the same force and effect as if made on such date.  The
interest installment so payable, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in the Indenture, be paid to

<PAGE>
 
the person in whose name this Debenture (or one or more Predecessor Securities,
as defined in said Indenture) is registered at the close of business on the
regular record date for such interest installment, which, subject to the
following sentence, shall be the close of business on the business day next
preceding such Interest Payment Date.  If pursuant to Section 305 of the
Indenture this series of Debentures is no longer represented by a Global
Security, the Company may select a regular record date for such interest
installment which shall be any date at least one Business Day before an Interest
Payment Date.  Interest payable on redemption or maturity shall be payable to
the person to whom the principal is paid.  Any such interest installment not
punctually paid or duly provided for shall forthwith cease to be payable to the
registered Holder on such regular record date and may be paid to the Person in
whose name this Debenture (or one or more Predecessor Securities) is registered
at the close of business on a special record date to be fixed by the Trustee for
the payment of such defaulted interest, notice whereof shall be given to the
registered Holder of this Debenture not less than 10 days prior to such special
record date, or may be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Debentures may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in the Indenture.  The principal of (and
premium, if any) and the interest on this Debenture shall be payable at the
office or agency of the Trustee maintained for that purpose in any coin or
currency of the United States of America that at the time of payment is legal
tender for payment of public and private debts; provided, however, that payment
of interest may be made at the option of the Company by check mailed to the
registered Holder at such address as shall appear in the Security Register.

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

The indebtedness evidenced by this Debenture is entitled to the benefits of a
Support Agreement, dated as of April 4, 1989, as amended as of May 15, 1989,
December 10, 1990, and February 14, 1991 (as such Agreement may be hereafter
amended, modified or supplemented from time to time in accordance with the terms
and conditions of the Indenture, the "Support Agreement") between the Company
and NIPSCO Industries, Inc. ("Industries").  The Support Agreement provides
that, during the term thereof, (i) Industries will own all of the voting stock
of the Company, (ii) Industries will cause the Company to have at all times a
positive net worth (net assets less intangible assets, if any), as determined in
accordance with generally accepted accounting principles, and (iii) if the
Company is unable to make timely payment of principal of or any premium or
interest on any Debt (as defined below) issued by the Company, Industries will,
at the request of the Company or any Lender (as defined below), provide funds to
the Company to make such payments.  The Support Agreement also provides that any
Lender to the Company shall have the right to demand that the Company enforce
its rights against Industries under the Support Agreement as described in the
previous sentence, and in the event that the Company fails to require Industries
to perform

                                      -2-
<PAGE>
 
such obligations or the Company defaults in the timely payment of principal of
or any premium or interest on any Debt owed to a Lender, such Lender may proceed
directly against Industries to enforce the Company's rights against Industries
under the Support Agreement or to obtain payment of such defaulted principal,
premium or interest owed to such Lender.

The Support Agreement provides that in no event may any Lender, on default of
the Company or Industries or upon failure by the Company or Industries to comply
with the Support Agreement, have recourse to or against the stock or assets of
Northern Indiana Public Service Company (``Northern Indiana'') or any interest
of the Company or Industries therein.  Notwithstanding this limitation, the
Support Agreement provides that funds available to Industries to satisfy any
obligations under the Support Agreement will include cash dividends paid by
Northern Indiana to Industries.

The term "Debt" is defined in the Support Agreement as debt securities or other
obligations and includes the Debentures.  The term "Lender"is defined in the
Support Agreement as any person, firm or corporation to which the Company is
indebted for money borrowed or to which the Company otherwise owes any Debt or
which is acting as trustee or authorized representative on behalf of such
person, firm or corporation.  The Indenture provides that each Holder of a
Debenture, as well as the Trustee, shall be considered a "Lender" for purposes
of the Support Agreement and shall have all rights of a "Lender" set forth
therein.

The Support Agreement may be amended or terminated at any time by the agreement
of Industries and the Company, provided that (i) no amendment regarding the
terms described above may be made unless all Lenders consent in advance and in
writing to such amendment, (ii) no amendment regarding any other term of the
Support Agreement may be made in a manner that adversely affects the rights of
Lenders unless all affected Lenders consent in advance and in writing to such
amendment, and (iii) no termination shall be effective until such time as all
Debt (including the Debentures) shall have been paid in full.

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

Unless the Certificate of Authentication hereon has been executed by the Trustee
referred to on the reverse side hereof, this Debenture shall not be entitled to
any benefit under the Indenture or be valid or obligatory for any purpose.

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

                                      -3-

                         (FORM OF REVERSE OF DEBENTURE)

This Debenture is one of a duly authorized series of Securities of the Company
(herein sometimes referred to as the "Debentures"), specified in the Indenture,
all issued or to be issued in one or more series under and pursuant to an
Indenture dated as of January ___, 1996, duly executed and delivered between the
Company, Industries and Chemical Bank, as Trustee (the "Trustee"), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the Holders of the
Debentures.  By the terms of the Indenture, the Debentures are issuable in
series that may vary as to amount, date of maturity, rate of interest and in
other respects as provided in the Indenture.  This series of Debentures is
limited in aggregate principal amount as specified in the Board Resolution
establishing such series of Debentures.

The Company shall have the right to redeem this Debenture at the option of the
Company, in whole or in part, at any time on or after ____________, 2006 (an
"Optional Redemption") at a redemption price (the "Optional Redemption Price")
equal to the percentage of the principal amount set forth below if redeemed
during the 12-month period beginning ______________ of the years indicated:

and thereafter at 100% of the principal amount thereof, in each case together
with accrued and unpaid interest, if any, to the date of redemption.  Any
redemption pursuant to this paragraph will be made upon not less than 30 nor
more than 60 days' notice at the Optional Redemption Price.  If the Debentures
are only partially redeemed by the Company pursuant to an Optional Redemption,
the Debentures will be redeemed pro rata or by lot or by any other method
utilized by the Trustee; provided that if, at the time of redemption, the
Debentures are registered as a Global Security, the Depositary shall determine
by lot the principal amount of such Debentures held by each Debentureholder to
be redeemed.

In the event of redemption of this Debenture in part only, a new Debenture or
Debentures of this series for the unredeemed portion hereof will be issued in
the name of the Holder hereof upon the cancellation hereof.

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

                                      -5-

The Indenture contains provisions permitting the Company and the Trustee, with
the consent of the Holders of not less than a majority in aggregate principal
amount of the Debentures of each series affected at the time outstanding, as
defined in the Indenture, to execute supplemental indentures for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of the Indenture or of any supplemental indenture or of modifying in
any manner the rights of the Holders of the Debentures; provided, however, that
no such supplemental indenture shall (i) extend the fixed maturity of any
Debentures of any series, or reduce the principal amount thereof, or reduce the
rate or extend the time of payment of interest thereon, or reduce any premium
payable upon the redemption thereof, without the consent of the Holder of each
Debenture so affected, or (ii) reduce the aforesaid percentage of Debentures,
the Holders of which are required to consent to any such supplemental indenture,
without the consent of the Holders of each Debenture then outstanding and
affected thereby.  The Indenture also contains provisions permitting the Holders
of a majority in aggregate principal amount of the Debentures of any series at
the time outstanding affected thereby, on behalf of all of the Holders of the
Debentures of such series, to waive any past default in the performance of any
of the covenants contained in the Indenture, or established pursuant to the
Indenture with respect to such series, and its consequences, except a default in
the payment of the principal of or premium, if any, or interest on any of the
Debentures of such series.  Any such consent or waiver by the registered Holder
of this Debenture (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such Holder and upon all future Holders and owners
of this Debenture and of any Debenture issued in exchange herefor or in place
hereof (whether by registration of transfer or otherwise), irrespective of
whether or not any notation of such consent or waiver is made upon this
Debenture.

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

The Company shall have the right at any time during the term of the Debentures
from time to time to extend the interest payment period of such Debentures to up
to 20 consecutive quarters (an "Extended Interest Payment Period"), at the end
of which period the Company shall pay all interest then accrued and unpaid
(together with interest thereon compounded quarterly at the rate specified for
the Debentures to the extent that payment of such interest is enforceable under
applicable law); provided that, during such Extended Interest Payment Period,
the Company shall not declare or pay any dividend on, or purchase, acquire or
make a liquidation payment with respect to, any of its capital stock, or make
any payment of interest, principal or premium, if any, on or repay, repurchase,
redeem or otherwise acquire or make any sinking fund payment for the purchase or
redemption of any debt securities issued by the Company that rank pari passu
with or junior to the Debentures, or make any guarantee payments with respect to
any of the foregoing.  Before the termination of any such Extended Interest
Payment Period, the Company may further extend such Extended Interest Payment
Period, provided that such Extended Interest Payment Period, together with all
previous and further extensions thereof, shall not exceed 20 consecutive
quarters or extend beyond the maturity of the Debentures.  At the termination of
any such Extended Interest Payment Period and upon the payment of all accrued
and unpaid interest and any additional amounts then due, the Company may
commence a new Extended Interest Payment Period.

As provided in the Indenture and subject to certain limitations therein set
forth, this Debenture is transferable by the registered Holder hereof on the
Security Register of the Company, upon

                                      -6-
<PAGE>
 
surrender of this Debenture for registration of transfer at the office or agency
of the Company in the City and State of New York accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company or the
Trustee duly executed by the registered Holder hereof or his or her attorney
duly authorized in writing, and thereupon one or more new Debentures of
authorized denominations and for the same aggregate principal amount and series
will be issued to the designated transferee or transferees.  No service charge
will be made for any such transfer, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in relation
thereto.

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

No recourse shall be had for the payment of the principal of or the interest on
this Debenture, or for any claim based hereon, or otherwise in respect hereof,
or based on or in respect of the Indenture, against any officer or director,
past, present or future, as such, of the Company or of any predecessor or
successor corporation, whether by virtue of any constitution, statute or rule of
law, or by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of the consideration for

                    RE:  REGISTRATION STATEMENT ON FORM S-3
                         ----------------------------------

Ladies and Gentlemen:

     We have acted as special tax counsel to NIPSCO Capital Markets, Inc.
(the "Company") and NIPSCO Industries, Inc. ("Industries") in connection with
the preparation and filing of a Registration Statement on Form S-3 (the
"Registration Statement") and the prospectus contained therein (the
"Prospectus") and related documents with respect to the underwritten public
offering of the Company's Junior Subordinated Deferrable Interest Debentures,
Series A (the "Series A Debentures") and Industries' related obligations under
the Support Agreement, dated as of April 4, 1989, as amended, between the
Company and Industries.  In connection therewith, we have participated in the
preparation of, and have reviewed, the Registration Statement and Prospectus.

     In connection with this opinion, we have reviewed the Registration
Statement and, the following documents, in each case as filed with the
Registration Statement:  (i) the form of subordinated debt securities indenture
(the "Indenture") to be entered into among the Company, Industries, and Chemical
Bank, as trustee (the "Trustee"), (ii) the form of resolutions to be adopted by
the Board of Directors of the Company establishing the terms of the Series A
Debentures (the "Board Resolutions"), and (iii) the form of subordinated
debenture to be used to evidence the Series A Debentures (the "Form of
Debenture").  We have also reviewed such other documents and matters of law as
we consider necessary for the purposes of this opinion.

     Based on the foregoing and assuming that the Indenture is executed and
delivered by the Company, Industries and the Trustee, the Board Resolutions are
adopted by the Board of Directors of the Company, and the Form of Debenture is
approved by the Board of Directors of the Company, in each case in substantially
the form we have reviewed, we are of the opinion that the description of United
States federal income tax law included in the Prospectus under the caption
"United States Tax Considerations" is a fair and accurate summary of the matters
addressed therein, based upon the laws, regulations, rulings and decisions in
effect on the date of the Prospectus and the assumptions stated or referred to
therein.

     Our opinion is based on present law and existing interpretations thereof
by the courts and the Internal Revenue Service.  Any change in the facts,
currently or in the future, or any change in the law or existing interpretations
thereof, may adversely affect our opinion.  Further, our opinion is not binding
on the Internal Revenue Service and the tax effects discussed in the Prospectus
are not subject to absolute resolution prior to the running of the statute of
limitations or the rendering of a final determination by a court of law or by
closing agreement with the Internal Revenue Service.

     We do not express any opinion herein as to matters governed by any law
other than the federal income tax law of the United States of America, and we
undertake no obligation to advise you of changes that may subsequently come to
our attention.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name under the captions "United
States Tax Considerations" and "Legal Matters" in the Prospectus.

                                 Very truly yours,
