                                     PART I

ITEM 1. BUSINESS

                       OVERVIEW OF CONSOLIDATED BUSINESS

     NiSource Inc. (NiSource), formerly NIPSCO Industries, Inc., is an energy
and utility-based holding company headquartered in Merrillville, Indiana, that
provides natural gas, electricity and water to the public for residential,
commercial and industrial uses. NiSource was organized as an Indiana holding
company in 1987 under the name "NIPSCO Industries, Inc.," and changed its name
to NiSource Inc. on April 14, 1999, to reflect its new direction as a
multi-state supplier of energy and water resources and related services.

     NiSource's gas business is comprised primarily of regulated gas utilities
that operate throughout northern Indiana and New England. In addition, NiSource
expanded its gas marketing, trading and storage operations with the April 1999
acquisition of TPC Corporation, now renamed EnergyUSA-TPC Corp. (TPC).
NiSource's electric business is comprised of a regulated electric utility that
operates in northern Indiana. The electric business also includes wholesale
sales and power marketing activities. NiSource's regulated gas and electric
subsidiaries are collectively referred to as the "Energy Utilities." NiSource's
regulated water subsidiaries are collectively called the "Water Utilities."
Collectively the Energy and Water Utilities are referred to as the "Utilities."

     Non-regulated energy and utility-related products and services are provided
through the "Products and Services" subsidiaries. Products and Services
subsidiaries perform energy-related services and offer products in connection
with these services, which include pipeline construction, repair and maintenance
of underground gas pipelines and locating and marking utility lines.

     In addition to the Utilities and the Products and Services subsidiaries,
NiSource has a wholly-owned subsidiary, NiSource Capital Markets, Inc. (Capital
Markets), which engages in financing activities for NiSource and certain of its
subsidiaries, excluding Northern Indiana Public Service Company (Northern
Indiana).

     In June 1999, NiSource commenced a tender offer to acquire Columbia Energy
Group (CEG). In December 1999, CEG acknowledged preliminary indications of
interest from numerous other third parties and invited formal bids from those
companies that had indicated a preliminary value higher than the NiSource tender
offer price of $74 per share. As a result, in December, NiSource wrote off the
costs associated with its tender offer. On February 11, 2000, the NiSource
tender offer expired.

     On February 28, 2000, after completion of the bidding process initiated by
CEG, NiSource and CEG announced approval of a merger agreement under which
NiSource will form a new holding company, which will acquire all of the
outstanding shares of CEG valued at approximately $6 billion. The new holding
company will also assume approximately $2.5 billion of CEG debt. Under the
agreement, CEG shareholders have the option to receive new holding company stock
for up to 30% of the outstanding CEG shares. Under the common stock option, each
CEG share will be exchanged for $74 in new holding company stock, based on the
average NiSource share price prior to the closing, but not more than 4.4848
shares of new holding company stock for each CEG share. Under the cash option,
each CEG share will be exchanged for $70 in cash plus a $2.60 face value unit
(consisting of a zero coupon debt security with a forward equity contract). A
commitment letter was accepted under which certain financial institutions
agreed, under specified conditions, to provide up to $6.0 billion to finance the
acquisition of CEG. The merger is conditioned upon, among other things, the
approvals of the shareholders of both companies and various regulatory
commissions. If NiSource shareholder approval is not obtained, the merger
agreement provides that the transaction will automatically be restructured to
eliminate the 30% common stock option for CEG shareholders.

     See "Segments of Business" in the Notes to Consolidated Financial
Statements and "Selected Supplemental Information" in the 1999 Annual Report to
Shareholders regarding financial information about industry segments and classes
of customers served (see Exhibit 13).

                              ELECTRIC OPERATIONS

     Northern Indiana, NiSource's largest and dominant subsidiary, is a public
utility operating company incorporated in Indiana on August 2, 1912, that
supplies natural gas and electric energy to the public. It operates in 30
counties in the northern part of Indiana, serving an area of about 12,000 square
miles with a population of approximately 2.2 million. At December 31, 1999,
Northern Indiana served approximately 425,833 customers with electricity.

     Northern Indiana owns and operates four coal-fired electric generating
stations with net capabilities of 3,179,000 kilowatts (kw), two hydroelectric
generating plants with net capabilities of 10,000 kw and four gas-fired
combustion turbine generating units with net capabilities of 203,000 kw for a
total system net capability of 3,392,000 kw. During the year ended December 31,
1999, Northern Indiana generated 89.9% and purchased 10.1% of its electric
requirements.

     Northern Indiana's 1999 electric control area peak load (the highest level
of electrical utility usage in the control area) of 3,307,340 kw was set on July
30, 1999. Northern Indiana's electric control area includes Northern Indiana,
Wabash Valley Power Association, Inc. (WVPA) and Indiana Municipal Power Agency
(IMPA). The 1999 peak established a new all time peak, exceeding the old peak of
3,161,200 kw previously set on July 14, 1995. Northern Indiana's 1999 internal
peak load, which excludes WVPA and IMPA, of 2,962,340 kw was also set on July
30, 1999. This also established a new all-time internal peak load, exceeding the
old peak of 2,888,450 kw previously set on August 6, 1996.

     Northern Indiana's electric system is interconnected with the systems of
Ameren Services Corporation (formerly Central Illinois Public Service Company),
American Electric Power, Commonwealth Edison Company (ComEd), Cinergy Services,
Inc. and Consumers Energy. Electric energy is purchased from, sold to or
exchanged with various other utilities and power marketers under Northern
Indiana's power sales and open access transmission tariffs.

     Northern Indiana provides WVPA with transmission and distribution service,
operating reserve requirements and capacity deficiency service and provides IMPA
with transmission service, operating reserve requirements and capacity
deficiency service, in Northern Indiana's control area. Northern Indiana also
engages in sales and services under interconnection agreements with WVPA and
IMPA.

     WVPA provides service to 12 Rural Electric Membership Corporations (REMC's)
located in Northern Indiana's control area. IMPA provides service to the
municipal electric system of the city of Rensselaer located in Northern
Indiana's control area.

     Northern Indiana and WVPA have executed a supplemental agreement for unit
peaking capacity and energy. Unit peaking capacity is the capacity used to serve
peak demand from a specific peaking generating unit. Pursuant to this agreement,
which runs through December 2001, WVPA purchases 90,000 kw of capacity per
month.

     Northern Indiana serves the Town of Argos as a full requirement customer
and provides network integration service to seven other municipal wholesale
customers.

     Northern Indiana is a member of the East Central Area Reliability
Coordination Agreement (ECAR). ECAR is one of nine regional electric reliability
councils established to coordinate planning and operations of member electric
utilities regionally and nationally.

     Fuel Supply. The generating units of Northern Indiana are located at
Bailly, Mitchell, Michigan City and Schahfer Generating Stations. Northern
Indiana's 13 steam generating units have a net capability of 3,179,000 kw. Coal
is the primary source of fuel for all units, except for three, which utilize
natural gas. In addition, Northern Indiana's four combustion turbine generating
units with a net capability of 203,000 kw are fired by gas. Fuel requirements
for Northern Indiana's generation for 1999 were supplied as follows:

     In 1999, Northern Indiana used approximately 9.0 million tons of coal at
its generating stations. Northern Indiana has established a normal level of coal
stock that is expected to provide adequate fuel supply during the year.

     Annual coal requirements for Northern Indiana's electric generating units
through 2003 are estimated to range from 9.4 million tons to 9.7 million tons,
depending from year to year upon anticipated sales levels, scheduled maintenance
and other variables. These requirements are being met or will be met in part
under long-term contracts as follows:

                             GAS UTILITY OPERATIONS

     Northern Indiana, Bay State Gas Company (BSG), Northern Utilities, Inc.
(Northern Utilities), Kokomo Gas and Fuel Company (Kokomo Gas) and Northern
Indiana Fuel and Light Company (NIFL), combined, are the tenth largest local
natural gas distribution company in the nation, servicing more than one million
gas customers.

     Northern Indiana. Northern Indiana supplies natural gas of about 1,000
British thermal units (Btu) per cubic foot. In a 24-hour period ended January 5,
1999, Northern Indiana's 1999 maximum day send-out (the maximum amount of gas
delivered through Northern Indiana's distribution system to its end customers)
was 1.7 million dekatherms (dth). Northern Indiana's total gas send-out for 1999
was 282.5 million dth, compared to 266.0 million dth in 1998.

                                        4
<PAGE>   5

     Agreements have been negotiated with natural gas suppliers to replace
former pipeline supplier contracts pursuant to the requirements of Federal
Energy Regulatory Commission (FERC) Order No. 636. Northern Indiana also has
agreements which allow for the purchase of gas either from gas marketers or
producers.

     Northern Indiana has firm transportation agreements with pipelines, which
allow Northern Indiana to move its gas through the pipelines' transmission
systems. In 1999, all of the gas supplied by Northern Indiana was transported by
ANR Pipeline Company (ANR), Crossroads Pipeline Company (Crossroads), a
subsidiary of NiSource, Midwestern Gas Transmission Company (Midwestern),
Natural Gas Pipeline Company of America (Natural), Panhandle Eastern Pipe Line
Company (Panhandle), Tennessee Gas Pipeline Company (Tennessee) and Trunkline
Gas Company (Trunkline). The transportation rates of Crossroads and the
transportation and storage rates of ANR, Midwestern, Natural, Panhandle,
Tennessee and Trunkline to Northern Indiana are subject to change in accordance
with rate proceedings filed with the FERC.

     Approximately 77% of Northern Indiana's 1999 gas supply was purchased on
the spot market, generally on less than 30-day agreements. The average price per
dth (including FERC Order No. 636 transition charges) in 1999 was $2.56,
compared to $2.49 in 1998, and the average cost of purchased gas, after
adjustment for transition charges billed to transport customers, was $2.58 per
dth, as compared to $2.48 per dth in 1998.

     Northern Indiana has a curtailment plan (a plan which outlines service to
be curtailed in the event of limited gas supply) that has been approved by the
Indiana Utility Regulatory Commission (IURC). There were no firm sales
curtailments in 1999 and none are expected during 2000.

     Northern Indiana operates an underground gas storage field at Royal Center,
Indiana, which currently has a storage capacity of 6.75 million dth. Withdrawals
were made in the 1999-2000 winter of up to 103,126 dth per day. In addition,
Northern Indiana has several gas storage service agreements which make possible
the withdrawal of substantial quantities of gas from other storage facilities.
All of the storage agreements have limitations on the volume and timing of daily
withdrawals. These contracts provide in the aggregate for approximately 29.6
million dth of annual stored volume and allow for approximately 661,000 dth of
maximum daily withdrawal.

     Northern Indiana has a liquefied natural gas plant in LaPorte County which
is designed for peak shaving (the process of supplementing gas supply during
periods of high demand) and has the following capacities: maximum storage of 4
million dth; maximum liquefaction rate (gas to liquid), 20,000 dth per day;
maximum vaporization rate (output to distribution system), 300,000 dth per day.

     PNGTS. PNGTS is a 292-mile pipeline in northern New England in which
NiSource subsidiaries have a combined interest of 19.06%.

     Gas Cost Adjustment Clause. Metered gas rates may be adjusted to reflect
the cost of purchased gas, contracted gas storage and storage transportation
charges. See "Summary of Significant Accounting Policies--Gas Cost Adjustment
Clause" in the Notes to Consolidated Financial Statements in the 1999 Annual
Report to Shareholders (see Exhibit 13).

                                WATER OPERATIONS

     The Water Utilities supply water for residential, commercial and industrial
uses and for fire protection service in Indianapolis, Indiana and surrounding
areas. The territory served by the Water Utilities covers an area of
approximately 650 square miles in seven counties of central Indiana and the
Water Utilities served approximately 275,688 customers at December 31, 1999.

     The combined maximum daily capacity of the Water Utilities' treatment
plants, together with the maximum daily capacity of the three primary well
fields, is 247 million gallons per day (MGD). During 1999, the average daily
consumption was 146 MGD and the maximum daily consumption was 221 MGD.

     The principal sources of the Indianapolis Water Company (IWC) and IWC
Morgan Water Company water supplies are the White River, which flows through
Indianapolis from north to south and is supplemented by Morse Reservoir on a
tributary, Cicero Creek; Fall Creek, which flows through Indianapolis from the
northeast and is supplemented by Geist Reservoir; the city of Indianapolis'
Eagle Creek Reservoir, located on Eagle Creek in northwest Marion County, from
which water is purchased under a long-term contract; Geist Well Field, a ground
water supply located downstream of Geist Reservoir; and South Well Field located
in southern Marion and northern Johnson Counties. The principal source of water
for Harbour Water Corporation, Liberty Water Corporation, Lawrence Water
Company, Inc. and The Darlington Water Works Company are derived from wells
within their service territory.

     The three large surface reservoirs are essential to providing an adequate
supply during dry periods. Two are used to supplement low stream flows in the
White River and Fall Creek, respectively, and water is drawn directly from the
third. The reservoirs are designed to maintain an adequate water supply in the
event of a repetition of the worst two-year drought ever recorded in the
Indianapolis area. The theoretical dependable supply from the three reservoirs
including natural stream flows represents approximately 63% of the total
dependable supply available to IWC with the balance supplied by natural stream
flow and wells.

     The Water Utilities have aquifer protection plans for Geist and South Well
Fields. Once fully developed, the Geist Well Field will produce 12 to 15 MGD
while the South Well Field will produce 48 MGD. The protection plans will guide
the Water Utilities' development of these newest major sources of supply and
result in land use plans to protect the aquifer systems from potential
contamination sources.

                                 GAS MARKETING

     On April 1, 1999, NiSource acquired the stock of TPC, a natural gas storage
and marketing company based in Houston, Texas. As a result of the TPC
acquisition, NiSource had an indirect investment representing a 77.3% interest
in Market Hub Partners, L. P. (MHP), a Delaware limited partnership. During the
fourth quarter of 1999, NiSource subsidiaries purchased the remaining interests
in MHP.

     TPC. TPC is a major natural gas marketer and gas asset portfolio manager.
During 1999, TPC assumed the operations of NESI Energy Marketing LLC (NEM) which
provided natural gas sales and management services to industrial and commercial
customers, engaged in natural gas marketing activities and provided gas supply
to Northern Indiana, Kokomo Gas and NIFL under spot and /or term contracts.
During 1999, TPC and NEM had combined sales of approximately 317 million dth.

     MHP. MHP is one of the largest owners and operators of high deliverability
salt cavern natural gas storage capacity in North America. MHP's Moss Bluff and
Egan facilities, located near Houston, Texas, and
                                        7
<PAGE>   8

in Acadia Parish, Louisiana, respectively, are strategically positioned at
industry-recognized market hubs near the convergence of major natural gas
pipelines and serve as aggregation points for natural gas collected along the
Texas and Louisiana Gulf Coast. The Moss Bluff and Egan facilities have
bi-directional interconnects to five pipelines, which form hub and spoke systems
and enable MHP to provide its customers with storage and other services that
allow better management of their variable gas load requirements. At December 31,
1999, MHP's two facilities maintained approximately 22.7 billion cubic feet
(bcf) of natural gas working storage capacity, 91.6% of which was leased under
storage contracts with major utilities, pipeline companies, local distribution
companies, natural gas producers and natural gas marketers. These storage
contracts provide a minimum level of revenue regardless of usage by the
customer. MHP supplements these revenues by providing a variety of load
management services. On February 17, 2000, drilling began at a third storage
facility located in Tioga County, Pennsylvania. The new facility is scheduled to
be completed in mid-June 2000. MHP performs storage services under long-term
demand contracts as well as various other hub services for Northern Indiana and
TPC.

     Primary has advanced approximately $36.6 million and $31.8 million, at
December 31, 1999 and December 31, 1998, respectively, to the lessors of the
energy-related projects discussed above. Primary is evaluating other potential
projects with Northern Indiana customers as well as with potential customers
outside of Northern Indiana's service territory. Projects under consideration
include those which use industrial by-product fuels and natural gas to produce
electricity.

ENERGYUSA, INC. (EUSA). EUSA coordinates the energy-related diversification
efforts of NiSource.

     EnergyUSA Commercial Energy Services, Inc. (Commercial). Commercial
provides energy solutions, which enhance its customers' competitiveness through
cost reductions, modernizing infrastructure and improving cost accountabilities,
including marketing energy efficient lighting solutions. During 1999, the
operations of all the Savage companies, which were acquired in the February 1999
purchase of BSG, including Savage ALERT, a company that serves the energy and
HVAC engineering needs of large-scale commercial customers in 22 states, were
reorganized under Commercial.

     SM&P Utility Resources Inc.(SM&P) and Underground Technology, Inc. (UTI).
SM&P and UTI (of which NiSource owns 50%) provide underground facility locating
to utilities throughout the United States. During 1999, SM&P and UTI performed
6.6 million line locates making NiSource one of the largest locating providers
in the country.

     Miller Pipeline Corporation (Miller). Miller installs and maintains
underground pipelines for natural gas and water utilities and also sells
products and services related to infrastructure preservation and replacement.
During 1999, Miller had sales of $72.6 million and 512 customers nationwide.

     EnergyUSA Consumer Products Group (Consumer). Consumer provides home
products and propane sales, and participates in retail gas pilot programs in
Indiana, Ohio, Michigan, Massachusetts, New Hampshire and Maine.

NISOURCE DEVELOPMENT COMPANY, INC. (DEVELOPMENT). Through its subsidiaries,
Development makes various investments, primarily in real estate, intended to
complement NiSource's energy businesses. At December 31, 1999, Development has
$33.3 million of investments, at equity, relating to affordable housing projects
located primarily throughout Indiana. In 1992, it began the development of a
residential development located in Chesterton, Indiana which was substantially
complete at December 31, 1999.

CAPITAL MARKETS. Capital Markets provides financing for NiSource's subsidiaries
other than Northern Indiana and, in certain respects, IWC Resources Corporation
(IWCR) (the holding company for the Water Utilities) and BSG. As of December 31,
1999, Capital Markets had $137.0 million in commercial paper outstanding, having
a weighted average interest rate of 6.28%. Capital Markets has entered into a
five-year $100 million revolving credit agreement and a 364-day $100 million
revolving credit agreement with several banks. These agreements, which now
terminate on September 23, 2003 and September 23, 2000, respectively, provide
financing flexibility to Capital Markets and may be used to support the issuance
of commercial paper. At December 31, 1999, there were no borrowings outstanding
under either of these agreements. Capital Markets also has $163.0 million of
money market lines of credit. As of December 31, 1999, $142.5 million of
borrowings were outstanding under these lines of credit.

     The financial obligations of Capital Markets are subject to a Support
Agreement between NiSource and Capital Markets, under which NiSource has
committed to make payments of interest and principal on Capital
                                        9
<PAGE>   10

Markets' obligations in the event of a failure to pay by Capital Markets.
Restrictions in the Support Agreement prohibit recourse on the part of Capital
Markets' creditors against the stock and assets of Northern Indiana which are
owned by NiSource. Under the terms of the Support Agreement, in addition to the
cash flow of cash dividends paid to NiSource by any of its consolidated
subsidiaries, the assets of NiSource, other than the stock and assets of
Northern Indiana, are available as recourse for the benefit of Capital Markets'
creditors. The carrying value of the assets of NiSource, other than the assets
of Northern Indiana, as reflected in the consolidated financial statements of
NiSource, was approximately $3.2 billion at December 31, 1999.

                                   REGULATION

HOLDING COMPANY ACT. NiSource is currently exempt from registration with the
Securities and Exchange Commission (SEC) as a "registered holding company" under
the Public Utility Holding Company Act of 1935, as amended (Holding Company
Act). However, upon consummation of the acquisition of CEG, either the proposed
new holding company over NiSource or NiSource, whichever is the acquiring party,
will become a "registered holding company". As the result of registration, the
new combined NiSource/Columbia Energy System will be subject to regulation under
the Holding Company Act by the SEC, including, in the absence of exemption,
requirements for SEC approval for securities issuances and extensions of credit,
acquisitions and dispositions of utility property, acquisition of non-utility
business, and affiliate transactions between companies in the new system.
Registered systems are limited in the scope of their gas and utility operations
and in their ownership of non-utility businesses which are not functionally
related to their utility operations unless otherwise exempted under the Holding
Company Act. The Holding Company Act also regulates holding company system
service companies and the rendering of services by holding company affiliates to
other companies in their system.

STATE UTILITY REGULATORY COMMISSIONS. NiSource (the holding company) is not
subject to regulation by state utility and regulatory commissions since it is
not a public utility. NiSource and its non-utility subsidiaries are subject to
certain reporting and information access requirements under applicable state
law. Furthermore, certain contracts between NiSource or its non-utility
subsidiaries and the Utilities must be filed with, and in some cases approved
by, the appropriate state utility and regulatory commissions.

     The Utilities are subject to regulation by the applicable state utility
regulatory commission as to rates, service, accounts, and issuance of securities
and in other respects in the state where the Utilities provide service. The
Utilities are also subject to limited regulation by local public authorities.
The Texas Railroad Commission regulates Moss Bluff Development Corporation.

FEDERAL ENERGY REGULATORY COMMISSION. NiSource is not regulated by the FERC, but
any subsidiary that engages in FERC jurisdictional sales or activities,
including the Energy Utilities, is subject to such regulation.

     Northern Indiana's restructuring under NiSource was approved by a February
29, 1988 order of the FERC. The order is conditioned upon the FERC's continuing
authority to examine the books and records of NiSource and its subsidiaries,
upon further order of the FERC, and to make such supplemental orders, for good
cause, as it may find necessary or appropriate regarding the restructuring.

     In 1999, about 7% of Northern Indiana's electric revenues were derived from
electric service it furnished at wholesale in interstate commerce to other
utility companies, power marketers, municipalities and WVPA (see "Item 1.
Business-Electric Operations" regarding WVPA). Northern Indiana's wholesale
rates and operations are subject to the jurisdiction of the FERC. FERC
jurisdiction does not extend to the issuance of securities by Northern Indiana,
which are regulated by the IURC. The FERC has declared Northern Indiana, BSG,
Northern Utilities, Kokomo Gas and NIFL exempt from the provisions of the
Natural Gas Act.

     MHP's Egan Facility is a gas storage facility subject to regulation by the
FERC as to rates, service, accounts and in other respects. The FERC also
certificates certain facilities of MHP.

                                  RATE MATTERS

     For a description of Northern Indiana's Alternative Regulatory Plan (ARP)
See "Competition and Regulatory Changes" below.

     On January 27, 2000, the Citizens Action Coalition (CAC), a private
consumer organization, filed a petition before the IURC. The petition does not
seek a specified amount of rate reduction, but rather alleges that the existing
Northern Indiana electric rates are "unreasonable and unsafe," and seeks to have
the IURC force Northern Indiana to produce detailed financial calculations that
would justify its electric rates. Northern Indiana is opposing the petition on
both legal and factual grounds, and believes that its current rates are just and
reasonable as required by statute.

     On November 14, 1997, IWC petitioned the IURC for approval of new water
rates and charges. On March 17, 1998, IWC and the Office of Utility Consumer
Counselor (OUCC), representing the ratepayers, filed a "Stipulation and
Settlement Agreement" resolving the issues in the case. This agreement, approved
by the IURC on April 8, 1998, provided for an increase in IWC's water rates and
charges in two phases. The first phase was an immediate increase of
approximately $5,253,000. The second phase approved an additional increase of
approximately $4,540,000 on April 8, 1999. The agreement further provided that
prior to January 1, 2002, IWC cannot request an additional change in its basic
rates and charges nor seek authority to continue allowance for funds used during
construction (AFUDC) or defer depreciation on its capital projects after they
have been completed and are in service. Effective with the second phase of the
increase, IWC will use individual depreciation rates for each plant account as
approved by the IURC on January 15, 1997, to produce a composite depreciation
rate of 2.21%.

                       COMPETITION AND REGULATORY CHANGES

     The regulatory frameworks applicable to the Energy Utilities, at both the
state and federal levels, are undergoing fundamental changes. These changes have
impacted and will continue to have an impact NiSource's operations, structure
and profitability. At the same time, competition within the electric and gas
industries will create opportunities to compete for new customers and revenues.
Management has taken steps to become more competitive and profitable in this
changing environment, including partnering on energy projects with major
industrial customers, converting some of its generating units to allow use of
lower cost, low sulfur coal, providing its gas customers with increased customer
choice for new products and services, acquiring companies which increase our
scale and establishing subsidiaries that provide gas and develop new
energy-related products for residential, commercial and industrial customers.

THE ELECTRIC INDUSTRY. At the Federal level, the FERC issued Order No. 888-A in
1996 which required all public utilities owning, controlling or operating
transmission lines to file non-discriminatory open-access tariffs and offer
wholesale electricity suppliers and marketers the same transmission service they
provide themselves. In 1997, FERC approved Northern Indiana's open-access
transmission tariff. On December 20, 1999, FERC issued a final rule addressing
the formation and operation of Regional Transmission Organizations (RTOs). The
rule is intended to eliminate pricing inequities in the provision of wholesale
transmission service. NiSource does not believe that compliance with the new
rules will be material to its future earnings. Although wholesale customers
currently represent a small portion of Northern Indiana's electricity sales, it
intends to continue its efforts to retain and add wholesale customers by
offering competitive rates and also intends to expand the customer base for
which it provides transmission services.

     At the state level, NiSource announced in 1997 and 1998 that, if consensus
could be reached regarding electric utility restructuring legislation, NiSource
would support a restructuring bill before the Indiana General Assembly. During
1999, discussions were held with the other investor-owned utilities in Indiana
regarding the technical and economic aspects of possible legislation leading to
greater customer choice. A consensus was not reached. Therefore, NiSource did
not support legislation regarding electric restructuring during the 2000 session
of the Indiana General Assembly. During 2000, discussions will continue with all
segments of the Indiana electric industry in an attempt to reach a consensus on
electric restructuring legislation for introduction during the 2001 session of
the Indiana General Assembly.
                                       11
<PAGE>   12

THE GAS INDUSTRY. At the Federal level, gas industry deregulation began in the
mid-1980's when FERC required interstate pipelines to provide nondiscriminatory
transportation service pursuant to unbundled rates. This regulatory change
permitted large industrial and commercial customers to purchase their gas
supplies either from the Energy Utilities or directly from competing producers
and marketers which would then use the Energy Utilities' facilities to transport
the gas. More recently, the focus of deregulation in the gas industry has
shifted to the states.

     At the state level, the IURC approved in 1997 Northern Indiana's ARP which
implemented new rates and services that included, among other things, unbundling
of services for additional customer classes (primarily residential and
commercial users), negotiated services and prices, a gas cost incentive
mechanism and a price protection program. The gas cost incentive mechanism
allows Northern Indiana to share any cost savings or cost increases with its
customers based upon a comparison of Northern Indiana's actual gas supply
portfolio cost to a market-based benchmark price. Phase I of Northern Indiana's
Customer Choice Pilot Program ended March 31, 1999. This pilot program offered
82,000 residential customers within St. Joseph County and 10,000 commercial
customers throughout the NiSource service area the right to choose alternative
gas suppliers. Phase II of Northern Indiana's Customer Choice Pilot Program
commenced April 1, 1999 and will continue for a one-year period. During this
phase, Northern Indiana is offering customer choice to all 660,000 residential
and 50,000 commercial customers throughout its gas service territory. A limit of
150,000 residential and 20,000 commercial customers are eligible to enroll in
Phase II of the program. The IURC order allows a specific NiSource natural gas
marketing subsidiary to participate as a supplier of choice to Northern Indiana
customers. In addition, as Northern Indiana has allowed residential and
commercial customers to designate alternative gas suppliers, it has also offered
new services to all classes of customers including price protection, negotiated
sales and services, gas lending and parking, and new storage services.

     In Massachusetts, BSG implemented new unbundled rates and services for all
commercial-industrial customers in 1993, and launched one of the nation's
earliest residential and small commercial-industrial customer choice pilot
programs in 1996. The BSG pilot, in which almost 28% of eligible customers
participated, is scheduled to conclude on April 1, 2000 when all Massachusetts
gas utilities are expected to begin making unbundled gas service available to
all customer classes pursuant to new statewide model terms and conditions that
are currently awaiting approval by the Massachusetts Department of
Telecommunications and Energy.

     In New Hampshire, Northern Utilities introduced unbundled tariffs and
services for all commercial-industrial customers in 1994. In 1998, the New
Hampshire Public Utilities Commission (NHPUC) formed a collaborative group to
investigate the merits of further unbundling and advise the NHPUC accordingly.
The collaborative group has recommended new model tariffs and regulation
designed to make unbundled services available to all commercial-industrial
customers statewide on November 1, 2000, with consideration of residential
unbundling at a later date. Hearings before the NHPUC regarding the
recommendations are expected to be held during the first quarter of 2000.

     In Maine, Northern Utilities introduced unbundled rates and services for
large commercial-industrial customers in December 1995 and expanded the
availability to all daily metered commercial and industrial customers on
November 1, 1999. In June 1999 the Maine Public Utilities Commission (MPUC)
opened an inquiry into the potential merits of further regulatory changes
related to unbundling. This inquiry is intended to investigate all the key
elements of full customer choice and will include a review of customer choice
programs in Massachusetts and New Hampshire.

     To date, the Energy Utilities have not been materially affected by
competition and management does not foresee substantial adverse affects in the
near future unless the current regulatory structure is substantially altered.
NiSource believes the steps that it has taken to deal with increased competition
has had and will continue to have significant positive effects in the next few
years.

                                       12
<PAGE>   13

                                   EMPLOYEES

     NiSource had 7,399 employees at December 31, 1999. Of these employees,
3,549 are represented by various local unions. The total number of employees at
Northern Indiana was 3,077; at SM&P, 1,365; at BSG, 919; at Miller, 762; at IWC,
433; and NiSource had 843 employees in remaining operations.

                             ENVIRONMENTAL MATTERS

GENERAL. The operations of NiSource are subject to extensive and evolving
federal, state and local environmental laws and regulations intended to protect
the public health and the environment. Such environmental laws and regulations
affect operations as they relate to impacts on air, water and land.

SUPERFUND. Because several NiSource subsidiaries are "potentially responsible
parties" (PRPs) under the Comprehensive Environmental Response, Compensation and
Liability Act (CERCLA) at several waste disposal sites, as well as at former
manufactured-gas plant sites which it, or its corporate predecessors, own or
owned or operated, it may be required to share in the costs of clean up of such
sites. A program was instituted to investigate former manufactured-gas plant
sites where it is the current or former owner, which investigation has
identified forty-six such sites. Initial sampling has been conducted at thirty
sites. Investigation activities have been completed at twenty-three sites and
remedial measures have been selected or implemented at sixteen sites. NiSource
intends to continue to evaluate its facilities and properties with respect to
environmental laws and regulations and take any required corrective action.

     In an effort to recover a portion of the costs related to the former
manufactured gas plants, various companies that provided insurance coverage
which NiSource believed covered costs related to former manufactured-gas plant
sites were approached. Northern Indiana filed claims in Indiana state court
against various insurance companies, seeking coverage for costs associated with
several manufactured-gas plant sites and damages for alleged misconduct by some
of the insurance companies. Settlements have been reached with all insurance
companies. Additionally, agreements have been reached with other Indiana
utilities relating to cost sharing and management of the investigation and
remediation of several former manufactured-gas plant sites at which Northern
Indiana and such utilities or their predecessors were operators or owners.

     BSG and Northern Utilities have rate recovery for environmental response
costs in Maine, Massachusetts and New Hampshire. The rate treatment allows for
the recovery of 100% of prudently incurred costs for investigation and
remediation over a 5-7 year period from date of payment. Recoveries from third
parties or insurance companies in Maine and Massachusetts are allocated 50% to
rate payers and 50% to shareholders. In New Hampshire 100% of any recoveries
from third parties or insurance companies are returned to rate payers.

     As of December 31, 1999, a reserve of approximately $23.8 million has been
recorded to cover probable corrective actions. The ultimate liability in
connection with these sites will depend upon many factors, including the volume
of material contributed to the site, the number of the other PRPs and their
financial viability, the extent of corrective actions required and rate
recovery. Based upon investigations and management's understanding of current
environmental laws and regulations, NiSource believes that any corrective
actions required, after consideration of insurance coverages, contributions from
other PRPs and rate recovery, will not have a material effect on its financial
position or results of operations.

CLEAN AIR ACT. The Clean Air Act Amendments of 1990 (CAAA) impose limits to
control acid rain on the emission of sulfur dioxide and nitrogen oxides (NOx)
which become fully effective in 2000. All of NiSource's facilities are already
in compliance with the sulfur dioxide limits. NiSource has already taken most of
the steps necessary to meet the NOx limits.

     The CAAA also contain other provisions that could lead to limitations on
emissions of hazardous air pollutants and other air pollutants (including NOx as
discussed below), which may require significant capital expenditures for control
of these emissions. Until specific rules have been issued that affect NiSource's
facilities, what these requirements will be or the costs of complying with these
potential requirements cannot be predicted.
                                       13
<PAGE>   14

NITROGEN OXIDES. During 1998, the Environmental Protection Agency (EPA) issued a
final rule, the NOx State Implementation Plan (SIP) call, requiring certain
states, including Indiana, to reduce NOx levels from several sources, including
industrial and utility boilers. The EPA stated that the intent of the rule is to
lower regional transport of ozone impacting other states' ability to attain the
federal ozone standard. According to the rule, the State of Indiana must issue
regulations implementing the control program. The State of Indiana, as well as
some other states, filed a legal challenge in December 1998 to the EPA NOx SIP
call rule. Lawsuits have also been filed against the rule by various groups,
including utilities. On May 25, 1999, the United States Court of Appeals for the
D.C. Circuit issued an order staying the NOx SIP call rule's September 30, 1999,
deadline for the state submittals until further order of the court. In a March
3, 2000 decision, the United States Court of Appeals for the D.C. Circuit ruled
largely in favor of EPA's regional NOx plan. An appeal of this decision is
expected. The State of Indiana in February 2000 proposed a moderate NOx control
plan designed to address Indiana's ozone nonattainment areas and regional ozone
transport. Any NOx emission limitations resulting from these actions could be
more restrictive than those imposed on electric utilities under the CAAA's acid
rain NOx reduction program described above. NiSource is evaluating the court
decision and any potential requirements that could result from the rules as
implemented by the State of Indiana. NiSource believes that the costs relating
to compliance with the new standards may be substantial, but such costs are
dependent upon the outcome of the current litigation and the ultimate control
program agreed to by the targeted states and the EPA. Northern Indiana is
continuing its programs to reduce NOx emissions and NiSource will continue to
closely monitor developments in this area.

     In a related matter to EPA's NOx SIP call, several Northeastern states have
filed petitions with the EPA under Section 126 of the Clean Air Act. The
petitions allege harm and request relief from sources of emissions in the
Midwest that allegedly cause or contribute to ozone nonattainment in their
states. NiSource is monitoring EPA's decisions on these petitions and existing
litigation to determine the impact of these developments on Northern Indiana's
programs to reduce NOx emissions.

     The EPA issued final rules revising the National Ambient Air Quality
Standards for ozone and particulate matter in July 1997. On May 14, 1999, the
United States Court of Appeals for the D.C. Circuit remanded the new rules for
both ozone and particulate matters to the EPA. Once rectified, the revised
standards could require additional reductions in sulfur dioxide, particulate
matter and NOx emissions from coal-fired boilers (including Northern Indiana's
generating stations) beyond measures discussed above. Final implementation
methods will be set by the EPA as well as state regulatory authorities. NiSource
believes that the costs relating to compliance with any new limits may be
substantial but are dependent upon the ultimate control program agreed to by the
targeted states and the EPA. NiSource will continue to closely monitor
developments in this area and anticipates the exact nature of the impact of the
new standards on its operations will not be known for some time.

     In a letter dated September 15, 1999, the Attorney General of the State of
New York alleged that Northern Indiana violated the Clean Air Act by
constructing a major modification of one of its electric generating stations
without obtaining pre-construction permits required by the Prevention of
Significant Deterioration (PSD) program. The major modification allegedly took
place at the R. M. Schahfer Station when, "in approximately 1995-1997, Northern
Indiana upgraded the coal handling system at Unit 14 at the plant." While
Northern Indiana is investigating these allegations, Northern Indiana does not
believe that the modifications required pre-construction review under the PSD
program and believes that all appropriate permits were acquired.

CARBON DIOXIDE. Initiatives are being discussed both in the United States and
worldwide to reduce so-called "greenhouse gases" such as carbon dioxide and
other by-products of burning fossil fuels. Reduction of such emissions could
result in significant capital outlays or operating expenses to NiSource.

CLEAN WATER ACT AND RELATED MATTERS. NiSource's wastewater and water operations
are subject to pollution control and water quality control regulations,
including those issued by the EPA and the States of Indiana, Louisiana,
Massachusetts and Texas.

     Under the Federal Clean Water Act and state regulations, NiSource must
obtain National Pollutant Discharge Elimination System permits for water
discharges from various facilities, including electric
                                       14
<PAGE>   15

generating and water treatment stations and a propane plant. These facilities
either have permits for their water discharge or they have applied for a permit
renewal of any expiring permits. These permits continue in effect pending review
of the current applications.

     Under the Federal Safe Drinking Water Act (SDWA), the Water Utilities are
subject to regulation by the EPA for the quality of water sold and treatment
techniques used to make the water potable. The EPA promulgates
nationally-applicable maximum contaminant levels (MCLs) for contaminants found
in drinking water. Management believes the Water Utilities are currently in
compliance with all MCLs promulgated to date. The EPA has continuing authority,
however, to issue additional regulations under the SDWA. In August 1996,
Congress amended the SDWA to allow the EPA more authority to weigh the costs and
benefits of regulations being considered in some, but not all, cases. In
December 1998, EPA promulgated two National Primary Drinking Water rules, the
Interim Enhanced Surface Water Treatment Rule and the Disinfectants and
Disinfection Byproducts Rule. The Water Utilities must comply with these rules
by December 2001. Management does not believe that significant changes will be
required to the Water Utilities' operations to comply with these rules; however,
some cost expenditures for equipment modifications or enhancements may be
necessary to comply with the Interim Enhanced Surface Water Treatment Rule.
Additional rules are anticipated to be promulgated under the 1996 amendments.
Compliance with such standards could be costly and require substantial changes
in the Water Utilities' operations.

     Under a 1991 law enacted by the Indiana legislature, a water utility may
petition the IURC for prior approval of its plans and estimated expenditures
required to comply with the provisions of, and regulations under, the Federal
Clean Water Act and SDWA. Upon obtaining such approval, a water utility may
include such costs in its rate base for rate-making purposes, to the extent of
its estimated costs as approved by the IURC, and recover its costs of developing
and implementing the approved plans if statutory standards are met. The capital
costs for such new systems, equipment or facilities or modifications of existing
facilities may be included in a water utility's rate base upon completion of
construction of the project or any part thereof. Such an addition to rate base,
however, would effect a change in water rates. NiSource's principal water
utility, IWC, has agreed to a moratorium on water rate increases until 2002.
Therefore, recovery of any increased costs discussed above may not be timely.

                                YEAR 2000 COSTS

RISKS. "Year 2000 issues" were concerned with the ability of electronic
processing equipment to process date sensitive information and recognize the
last two digits of a date as occurring in or after the year 2000. Any failure in
any system could have resulted in material operational and financial risks.
Possible scenarios included a system failure in a generating plant, an operating
disruption of gas, electricity or water, or an inability to interconnect with
the systems of other utilities. Failure to achieve year 2000 readiness could
have had a material adverse effect on results of operations, financial position
and cash flows.

     The program to address risks associated with the year 2000 on both
information technology (IT) and non-IT systems was completed in a timely manner.

STATE OF READINESS. The NiSource year 2000 program consisted of four phases:
inventory (identifying systems potentially affected by the year 2000),
assessment (testing identified systems), remediation (correcting or replacing
non-compliant systems) and validation (evaluating and testing remediated systems
to confirm compliance). All phases in all subsidiaries were completed in a
timely manner.

     Because NiSource depends on outside suppliers and vendors with similar year
2000 issues, the ability of those suppliers and vendors to provide an
uninterrupted supply of goods and services was assessed. Critical vendors and
suppliers were contacted in order to investigate their year 2000 efforts. In
addition, electricity and gas industry groups such as North American Electric
Reliability Council, Electric Power Research Institute, and the American Gas
Association were helpful in evaluating the potential impact of year 2000
problems upon the electric grid systems and pipeline networks.

COSTS. The total cost of the NiSource year 2000 program was approximately $25.0
million. These costs were funded from operations. Costs related to the
maintenance or modification of existing systems are expensed as
                                       15
<PAGE>   16

incurred. Costs related to the acquisition of replacement systems are
capitalized. These costs did not have a material impact on results of
operations.

CONTINGENCY PLANS. NiSource developed its contingency plans to address the
possibility that any mission-critical system would be non-compliant. This
included identifying alternate suppliers and vendors, conducting staff training
and developing communication plans. In addition, NiSource evaluated its ability
to maintain or restore service in the event of a power failure or operating
disruption or delay, along with the limited ability to mitigate the effects of a
network failure by isolating its own network from the non-compliant segments of
the greater network. These contingency plans were completed during the second
quarter of 1999 and reviewed during the fourth quarter of 1999. They were not
needed for the century rollover.

RESULTS. NiSource did not experience any system failures as a result of the year
2000 issue.

                           FORWARD LOOKING STATEMENTS

     This report contains forward looking statements within the meaning of the
securities laws. Forward looking statements include terms such as "may", "will",
"expect", "believe", "plan" and other similar terms. NiSource cautions that,
while it believes such statements to be based on reasonable assumptions and
makes such statements in good faith, you can not be assured that the actual
results will not differ materially from such assumptions or that the
expectations set forth in the forward looking statements derived from such
assumptions will be realized. You should be aware of important factors that
could have a material impact on future results. These factors include weather,
the federal and state regulatory environment, the economic climate, regional,
commercial, industrial and residential growth in the service territories served
by NiSource's Utility subsidiaries, customers' usage patterns and preferences,
the speed and degree to which competition enters the utility industry, the
timing and extent of changes in commodity prices, changing conditions in the
capital and equity markets and other uncertainties, all of which are difficult
to predict, and many of which are beyond NiSource's control.

ITEM 2. PROPERTIES.

ELECTRIC. Northern Indiana owns and operates four coal fired electric generating
stations with net capabilities of 3,179,000 kw, two hydroelectric generating
plants with net capabilities of 10,000 kw and four gas fired combustion turbine
generating units with net capabilities of 203,000 kw, for a total system net
capability of 3,392,000 kw. It has 291 substations with an aggregate transformer
capacity of 23,036,200 kilovolts (kva). Its transmission system, with voltages
from 34,500 to 345,000 volts, consists of 3,068 circuit miles of line. The
electric distribution system extends into 21 counties and consists of 7,800
circuit miles of overhead and 1,571 cable miles of underground primary
distribution lines operating at various voltages from 2,400 to 12,500 volts.
Northern Indiana has distribution transformers having an aggregate capacity of
11,367,093 kva and 445,377 electric watt-hour meters.

GAS UTILITIES. See "Item 1. Business-Gas Operations". At December 31, 1999,
Northern Indiana's system consisted of approximately 13,924 miles of gas mains.
At December 31, 1999, BSG's system consisted of approximately 5,450 miles of
distribution mains; 116 vaporization and storage facilities; propane storage
tanks; 268,022 services; and 305,182 meters installed on customers' premises.
The physical properties of the NiSource gas utilities are located throughout
Northern Indiana and New England.

     The transmission and distribution system of the gas utilities are for the
most part located on or under public streets, and other public places or on
private property not owned by the Company, with easements from or consent of the
respective owners.

PIPELINES. Crossroads and Granite combined have approximately 300 miles of
interstate gas pipelines located in Indiana, Ohio, Maine, New Hampshire and
Massachusetts.

GAS MARKETING. MHP owns salt caverns used for natural gas storage which are
located in Texas and Louisiana and are described under "Item 1.
Business-Products and Services and Other Subsidiaries".

                                       16
<PAGE>   17

WATER. The Water Utilities' properties consist of land, easements, rights
(including water rights), buildings, reservoirs, canals, wells, supply lines,
purification plants, pumping stations, transmission and distribution pipes,
mains and conduits, meters and other facilities used for the collection,
purification and storage of water and the distribution of water to its
customers. The water system extend from well fields and raw water reservoirs on
Cicero Creek and Fall Creek, north and northeast of Indianapolis, and from the
intake structure in Indianapolis' Eagle Creek Reservoir, northwest of
Indianapolis, to the service connections of the ultimate consumer. The Water
Utilities have 30,018 fire hydrants and 3,528 miles of water mains.

PRODUCTS AND SERVICES. Through its subsidiaries, Development owns Southlake
Complex, a 325,000 square foot office building located in Merrillville, Indiana
and a golf course, surrounding residential development and land held for resale
in Chesterton, Indiana. Waterway Holding, Inc. owns parcels of land held for
development.

CHARACTER OF OWNERSHIP. Substantially all of the properties of Northern Indiana
and IWC are subject to the lien of their respective First Mortgage Indentures.
The principal offices and properties of NiSource and its subsidiaries are held
in fee and are free from other encumbrances, subject to minor exceptions, none
of which are of such a nature as to impair substantially the usefulness of such
properties. Many of the offices in various communities served are occupied by
subsidiaries of NiSource under leases. All properties are subject to liens for
taxes, assessments and undetermined charges (if any) incidental to construction.
It is NiSource's practice regularly to pay such amounts, as and when due, unless
contested in good faith. In general, the electric, gas and water lines and mains
are located on land not owned in fee but are covered by necessary consents of
various governmental authorities or by appropriate rights obtained from owners
of private property. NiSource does not, however, generally have specific
easements from the owners of the property adjacent to public highways over, upon
or under which its electric, gas and water lines and mains are located. At the
time each of the principal properties was purchased a title search was made. In
general, no examination of titles as to rights-of-way for electric, gas and
water lines and mains was made, other than examination, in certain cases, to
verify the grantors' ownership and the lien status thereof.

ITEM 3. LEGAL PROCEEDINGS.

     NiSource and its subsidiaries are parties to various pending proceedings,
including suits and claims against them for personal injury, death and property
damage. The nature of such proceedings and suits and the amounts involved are
routine for the kinds of businesses conducted by NiSource and its subsidiaries,
except as described under the captions "NESI Energy Marketing Canada Ltd.
Litigation" and "Environmental Matters" in the Notes to Consolidated Financial
Statements in the 1999 Annual Report to Shareholders (see Exhibit 13). No other
material legal proceedings against NiSource or its subsidiaries are pending or,
to the knowledge of NiSource, contemplated by governmental authorities or other
parties.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

     None

ITEM 5. MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.

     NiSource's common shares are listed and traded on the New York, Chicago and
Pacific stock exchanges. The table below indicates the high and low sales price
of NiSource's common shares, on the composite tape, during the periods
indicated. On December 16, 1997, the Board authorized a two-for-one split of
NiSource's common stock. The stock split was paid on February 20, 1998, to
shareholders of record at the close of business on January 30, 1998. The sales
prices and common dividends reported have been restated to reflect the
two-for-one stock split.

</TABLE>

     As of February 29, 2000, NiSource had 40,463 common shareholders of record.

     The policy of the Board has been to declare cash dividends on a quarterly
basis payable on or about the 20th day of February, May, August and November.
NiSource paid quarterly common dividends of $0.24 per share during 1998 and
quarterly common dividends of $0.255 per share during 1999. At its December 1999
meeting, the Board increased the quarterly common dividend to $0.27 per share,
payable on February 18, 2000.

     Holders of NiSource's common shares are entitled to receive dividends when,
as and if declared by the Board out of funds legally available therefor.
Although the Board currently intends to consider the payment of regular
quarterly cash dividends on common shares, the timing and amount of future
dividends will depend on the earnings of Northern Indiana and other
subsidiaries, their financial condition, cash requirements, any restrictions in
financing agreements and other factors deemed relevant by the Board. During the
next few years, it is expected that the great majority of earnings available for
distribution of dividends will depend upon dividends paid to NiSource by
Northern Indiana.

     The following limitations on payment of dividends and issuance of preferred
stock apply to Northern Indiana:

     When any bonds are outstanding under its First Mortgage Indenture, Northern
Indiana may not pay cash dividends on its stock (other than preferred or
preference stock) or purchase or retire common shares, except out of earned
surplus or net profits computed as required under the provisions of the
maintenance and renewal fund. At December 31, 1999, Northern Indiana had
approximately $136.1 million of retained earnings (earned surplus) available for
the payment of dividends. Future common share dividends by Northern Indiana will
depend upon adequate retained earnings, adequate future earnings and the absence
of adverse developments.

     So long as any shares of Northern Indiana's cumulative preferred stock are
outstanding, no cash dividends shall be paid on its common shares in excess of
75% of the net income available therefor for the preceding calendar year, unless
the aggregate of the capital applicable to stocks subordinate as to assets and
dividends, would equal or exceed 25% of the sum of all obligations evidenced by
bonds, notes, debentures or other securities, plus the total capital and
surplus. At December 31, 1999 , the sum of the capital applicable to stocks
subordinate to the cumulative preferred stock plus the surplus was equal to 43%
of the total capitalization including surplus.

     In connection with the foregoing discussion, see "Common Share Dividend" in
the Notes to Consolidated Financial Statements in the 1999 Annual Report to
Shareholders (see Exhibit 13).

(1) Compensation deferred at the election of the Named Officer is reported in
    the category and year in which such compensation was earned.

(2) All bonuses are paid pursuant to the Bonuses Plan, except for portions of
    the bonuses paid to Messrs. Mulchay, Yundt and Turner, which are described
    in Notes 6 and 7. The Bonus Plan is designed to supplement a conservative
    base salary with incentive bonus payments if targeted financial performance
    is attained. The 1999 target aggregate payout for the Bonus Plan for the
    Named Officers was $1,212,500, which was more than the actual aggregate
    payout for the Named Officers. See "Nominating and Compensation Committee
    Report on Executive Compensation."

(3) In accordance with applicable Securities and Exchange Commission rules, the
    amounts shown for each of the Named Officers do not include perquisites and
    other personal benefits, as the aggregate amount of such benefits is less
    than the lesser of $50,000 and 10% of the total salary and bonus of such
    Named Officer. In 1999, this amount includes a one-time relocation allowance
    of $85,305 and a related tax allowance of $60,412 for Mr. Yundt.

(4) The payouts shown are based on the value, at date of vesting, of restricted
    shares awarded under the Long-Term Incentive Plan which vested during the
    years shown. Vesting was based on meeting certain performance requirements.
    Total restricted shares held (assuming 100% vesting) and aggregate market
    value at December 31, 1999 (based on the average of the high and low sale
    prices of the Common Shares on that date as reported in The Wall Street
    Journal) for the Named Officers were as follows: Mr. Neale, 120,000 shares
    valued at $2,148,744; Messrs. Adik, Mulchay and Yundt, 50,000 shares, for
    each individual valued at $895,310; and Mr. Turner, 33,200 shares (includes
    9,201 shares purchased pursuant to the PE Plan described in footnote 6)
    valued at $594,504. Dividends on the restricted shares are paid to the Named
    Officers.

(5) The Chairman, President and Chief Executive Officer, the Senior Executive
    Vice President, the Executive Vice President, the Senior Vice Presidents,
    and certain Vice Presidents of NiSource and Northern Indiana have available
    to them a supplemental life insurance plan which provides split-dollar
    coverage of up to 3.5 times base compensation as of commencement of the plan
    in 1991 and could provide life insurance coverage after retirement if there
    is adequate cash value in the respective policy. "All other Compensation"
    represents Company contributions to the 401(k) Plan and the dollar value of
    the benefit to the Named Officers under the supplemental life insurance
    plan, as follows: Mr. Neale -- $1,066 401(k) Plan, $28,856 premium value and
    $3,543 term insurance cost; Mr. Adik1 -- $1,110 401(k) Plan, $3,474 premium
    value and $1,061 term insurance cost; Mr. Mulchay -- $362 401(k) Plan,
    $5,671 premium value and $1,130 term insurance cost; Mr. Yundt -- $2,976
    premium value and $800 term insurance cost and Mr. Turner -- $5,512 premium
    value and $1,884 term insurance cost. The value of the life insurance
    premiums paid by NiSource in excess of term insurance cost on behalf of the
    Named Officers under the supplemental life insurance plan has been restated
    for all periods in accordance with the present value interest-free loan
    method.

(6) Messrs. Mulchay and Yundt are also Presidents of Northern Indiana and BSG,
    respectively, and 50% of their annual incentive compensation is determined
    based on the financial performance of the business unit for which they are
    responsible.

(7) Mr. Turner is also President of Primary and participates in the Primary
    Energy Incentive Plan ("PE Plan"). The PE Plan provides for a bonus based on
    meeting certain financial performance criteria of Primary Energy. Under the
    PE Plan, $39,982 of Mr. Turner's bonus for 1999 was used to purchase Common
    Shares of NiSource on or about February 29, 2000, the date of payment of the
    bonus. The PE Plan provides that the Common Shares are restricted for a
    period of five years, and are subject to continued employment, except that
    they vest earlier in the event of the employee's retirement, death or
    disability.

     Option Grants in 1999. The following table sets forth grants of options to
purchase Common Shares made during 1999 to the Named Officers. No stock
appreciation rights were awarded during 1999.

(1) All options granted in 1999 are fully exercisable commencing one year from
    the date of grant. Vesting may be accelerated as a result of certain events
    relating to a change in control of NiSource. The exercise price and tax
    withholding obligation related to exercise may be paid by delivery of
    already owned Common Shares or by reducing the number of Common Shares
    received on exercise, subject to certain conditions.

(2) Based on an aggregate of 744,750 options granted to all employees in 1999.

(3) All options were granted at the average of high and low sale prices of the
    Common Shares as reported in The Wall Street Journal on the date of grant.

(4) Grant date present value is determined using the Black-Scholes option
    pricing model. The assumptions used in the Black-Scholes option pricing
    model were as follows: volatility -- 15.72% (calculated using

                                       25
<PAGE>   26

    daily Common Share prices for the twelve-month period preceding the date of
    grant); risk-free rate of return -- 5.87% (the rate for a ten-year U.S.
    treasury); dividend yield--$1.02; option term -- ten years; vesting -- 100%
    one year after date of grant; and an expected option term of 5.4 years. No
    assumptions relating to non-transferability or risk of forfeiture were made.
    Actual gains, if any, on option exercises and Common Shares are dependent on
    the future performance of the Common Shares and overall market conditions.
    There can be no assurance that the amounts reflected in this table will be
    achieved.

     Option Exercises in 1999. The following table sets forth certain
information concerning the exercise of options or stock appreciation rights
("SARs") during 1999 by each of the Named Officers and the number and value of
unexercised options and SARs at December 31, 1999.

</TABLE>

     The credited years of service for each of the Named Officers, pursuant to
the Supplemental Plan, are as follows: Gary L. Neale -- 25 years; Stephen P.
Adik -- 21 years; Patrick J. Mulchay -- 37 years; Jeffrey W. Yundt -- 20 years;
and Joseph L. Turner -- 28 years.

     Upon their retirement, regular employees and officers of NiSource and its
subsidiaries which adopt the plan (including directors who are also full-time
officers) will be entitled to a monthly pension in accordance with the
provisions of NiSource's pension plan, originally effective as of January 1,
1945. The directors who are not and have not been officers of NiSource are not
included in the pension plan. The pensions are payable out of a trust fund
established under the pension plan with The Northern Trust Company, trustee. The
trust fund consists of contributions made by NiSource and the earnings of the
fund. Over a period of years the contributions are intended to result in
over-all actuarial solvency of the trust fund. The pension plan of NiSource has
been determined by the Internal Revenue Service to be qualified under Section
401 of the Internal Revenue Code of 1986, as amended (the "Code").

     Pension benefits are determined separately for each participant. The
formula for a monthly payment for retirement at age 65 is 1.7% of average
monthly compensation multiplied by years of service (to a maximum of 30 years)
plus 0.6% of average monthly compensation multiplied by years of service over
30. Average monthly compensation is the average for the 60 consecutive
highest-paid months in the employee's last 120 months of service. Covered
compensation is defined as wages reported as W-2 earnings (up to a limit set
forth in the Code and adjusted periodically) plus any salary reduction
contributions made under the 401(k) Plan, minus any portion of a bonus in excess
of 50% of base pay and any amounts paid for unused vacation time and vacation
days carried forward from prior years. The benefits listed in the Pension Plan
table are not subject to any deduction for Social Security or other offset
amounts.

     NiSource also has a Supplemental Plan for officers. Participants in the
Plan are selected by the Board. Benefits from the Plan are to be paid from the
general assets of NiSource. The Supplemental Plan provides the larger of (i) 60%
of five-year average pay less Primary Social Security Benefits (prorated for
less than 20 years of service) and an additional 0.5% of 5-year average pay less
Primary Social Security Benefits per year for participants with between 20 and
30 years of service, or (ii) the benefit formula under NiSource's
                                       27
<PAGE>   28

Pension Plan. In either case, the benefit is reduced by the actual pension
payable from NiSource's Pension Plan. In addition, the Supplemental Plan
provides certain disability and pre-retirement death benefits for the spouse of
a participant.

     Change in Control and Termination Agreements. The Board of NiSource has
authorized Change in Control and Termination Agreements ("the Agreements") with
Mr. Neale and the Vice Presidents of NiSource (including each of the Named
Officers) (each such person being an "executive"). NiSource believes that these
Agreements and related shareholder rights protections are in the best interests
of the shareholders, to insure that in the event of extraordinary events,
totally independent judgment is enhanced to maximize shareholder value. The
Agreements, which are terminable upon three years' notice, provide for the
payment of three times then current annual base salary and target incentive
bonus compensation and the continuation of certain employee benefits for a
period of 36 months (the "Severance Period"), and a pro rata portion of the
executive's targeted incentive bonus for the year of termination. These benefits
are payable if the executive terminates employment for "Good Reason" or is
terminated by the company for any reason other than "Good Cause" within
twenty-four months following certain changes in control. Each of these
Agreements also provides for payment of these benefits if the executive
voluntarily terminates employment during a specified period within the
twenty-four months following the change in control.

     The executive would receive benefits from NiSource that would otherwise be
earned during the Severance Period under NiSource' Supplemental Plan and
qualified retirement plans. All stock options held by the executive would become
immediately exercisable upon the date of termination of employment, and the
restrictions would lapse on all restricted shares awarded to the executive. If
any penalty tax under the Code is imposed on the payment of amounts under the
contracts, NiSource would increase the payment to the extent necessary to
compensate the executive for the imposition of such tax.

     During the Severance Period, the executive and spouse would continue to be
covered by applicable health or welfare plans of NiSource. If the executive died
during the Severance Period, all amounts payable to the executive would be paid
to a named beneficiary. No amounts would be payable under the Agreements if the
executive's employment were terminated by NiSource for Good Cause (as defined in
the Agreements).

     The Agreement with Mr. Neale also provides for the same severance payments
as above described in the event his employment is terminated at any time by
NiSource (other than for Good Cause) or due to death or disability, or if he
voluntarily terminates employment with Good Reason (as defined in the
Agreements).

     Compensation of Directors. Each director who is not receiving a salary from
NiSource is paid $20,000 per year, $3,000 annually per standing committee on
which the director sits, $1,000 annually for each committee chairmanship, $1,000
for each Board meeting attended and $750 per committee meeting attended.
Directors of NiSource do not receive any additional compensation for services as
a director of any Company subsidiary, including Northern Indiana. Under a
deferred compensation arrangement, directors may have their fees deferred in the
current year and credited to an interest-bearing account or to a phantom stock
account for payment in the future.

     NiSource's Nonemployee Director Retirement Plan provides a retirement
benefit for each nonemployee director of NiSource who has completed at least
five years of service on the Board. The benefit will be an amount equal to the
annual retainer for Board service in effect at the time of the director's
retirement from the Board, to be paid for the lesser of ten years or the number
of years of service as a nonemployee director of NiSource.

     NiSource's Nonemployee Director Stock Incentive Plan provides for grants of
restricted Common Shares to nonemployee directors of NiSource. The Plan provides
for a grant of 2,000 shares to each person, other than an employee of NiSource,
who is elected or reelected as a director of NiSource at the time of such
election or reelection. The grants of restricted shares vest in 20% annual
increments, with full vesting five years after the date of award. In 1999, 2,000
restricted Common Shares were granted to each of Messrs. Rolland, Thompson and
Foster under this plan.

     NiSource's Nonemployee Director Restricted Stock Unit Plan, which was
adopted by the Board in December 1998 and made effective as of January 1, 1999,
is a phantom stock plan that provides for grants to
                                       28
<PAGE>   29

nonemployee directors of restricted stock units that have a value related to
NiSource's Common Shares. Each nonemployee director received an initial grant of
500 units in April 1999. Subsequent grants of 500 units will be made annually to
nonemployee directors upon election or re-election to the Board. The grants of
units vest in 20% annual increments, with full vesting five years after the date
of award, and the units have no voting or stock ownership rights. In 1999, 500
units were granted to Messrs. Decio, Welsh, Rolland, Thompson, Ribordy and
Foster and Drs. Woo and Beering.

     NiSource has adopted a Directors' Charitable Gift Program for nonemployee
directors. Under the program, NiSource makes a donation to one or more eligible
tax-exempt organizations as designated by each eligible director. NiSource
contributes up to an aggregate of $125,000 for each nonemployee director who has
served as a director of NiSource for at least five years and up to an additional
$125,000 (for an overall $250,000) for each nonemployee director who has served
ten years or more. Organizations eligible to receive a gift under the program
include charitable organizations and educational institutions located in Indiana
and educational institutions that the director attended or for which he or she
serves on its governing board. Individual directors derive no financial benefit
from the program, as all deductions relating to the charitable donations accrue
solely to NiSource. All current nonemployee directors are eligible to
participate in the program.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT.

     NiSource is not aware of any beneficial owner of more than 5% of its Common
Shares, as of January 30, 2000.

     The following table sets forth information as to the beneficial ownership

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

     On February 12, 1999, NiSource acquired BSG. Mr. Roger A. Young was
Chairman of the Board and Chief Executive Officer of BSG at the time of the
acquisition and held shares in BSG. Pursuant to the acquisition transaction, Mr.
Young received Common Shares and/or cash in exchange for his BSG shares in the
same proportion as other BSG shareholders. In connection with the BSG
acquisition transaction, Mr. Young was elected as a director of NiSource. BSG
entered into a nine month employment agreement with Mr. Young, guaranteed by
NiSource, and Mr. Young entered into a covenant not to compete with NiSource.
The employment agreement provided Mr. Young with a base compensation and a
performance-based bonus. For the nine month term of the employment contract, Mr.
Young received base compensation of $641,000 and earned a performance-based
bonus of $1,600,000. In consideration of Mr. Young's covenant not to compete, he
was paid $3,200,000. Some of the foregoing payments have been deferred at a
market rate of interest and no interest was paid to Mr. Young in 1999.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS

1. DIVIDENDS FROM SUBSIDIARIES

     Cash dividends paid to NiSource Inc. (NiSource) by its consolidated
subsidiaries were (in thousands of dollars): $239,200, $207,400 and $188,175 in
1999, 1998 and 1997, respectively.

2. SUPPORT AGREEMENT

     The financial obligations of NiSource Capital Markets, Inc. (Capital
Markets) are subject to a Support Agreement between NiSource and Capital
Markets, under which NiSource has committed to make payments of interest and
principal on Capital Markets' obligations in the event of a failure to pay by
Capital Markets. Restrictions in the Support Agreement prohibit recourse on the
part of Capital Markets' creditors against the stock and assets of Northern
Indiana Public Service Company (Northern Indiana) which are owned by NiSource.
Under the terms of the Support Agreement, in addition to the cash flow of cash
dividends paid to NiSource by any of its consolidated subsidiaries, the assets
of NiSource, other than the stock and assets of Northern Indiana, are available
as recourse for the benefit of Capital Markets' creditors. The carrying value of
the assets of NiSource, other than the stock and assets of Northern Indiana, as
reflected in the consolidated financial statements of NiSource, was
approximately $3.2 billion at December 31, 1999.

3. CONTINGENCIES

     NiSource and its subsidiaries are parties to various pending proceedings,
including suits and claims against them for personal injury, death, and property
damage. Such proceedings and suits, and the amounts involved, are routine
litigation and proceedings for the kinds of businesses conducted by NiSource and
its subsidiaries.

4. EARNINGS PER SHARE

     NiSource determines earnings per share in accordance with the provisions of
SFAS No. 128 "Earnings per Share," which requires NiSource to present basic
earning per share and diluted earnings per share in place of primary earnings
per share.

5. STOCK SPLIT

     On December 16, 1997, the Board authorized a two-for-one split of
NiSource's common shares. The stock split was paid February 20, 1998, to
shareholders of record at the close of business January 30, 1998. All references
to number of shares reported including per share amounts and stock option data
of NiSource's common shares reflect the two-for-one stock split as if it had
occurred at the beginning of the earliest period.

6. PURCHASE OF IWC RESOURCES CORPORATION

     On March 25, 1997, NiSource acquired all the outstanding common stock of
IWCR for $290.5 million. NiSource financed this transaction with debt of
approximately $83.0 million and issuance of approximately 10.6 million
NiSource's common shares. NiSource accounted for the acquisition as a purchase.
The purchase price was allocated to the assets and liabilities acquired based on
their fair values.

7. PURCHASE OF BAY STATE GAS COMPANY

     In February 1999, NiSource acquired Bay State Gas Company (BSG) in a
stock-for-stock transaction valued at $40 per BSG share. The transaction was
valued at approximately $551 million. BSG shareholders had the option of
exchanging their shares of BSG stock for cash, up to an aggregate sum of equal
to 50% of the total purchase price (and exercised this option with respect to
approximately 43% of the total purchase price). BSG, one of the largest natural
gas utilities in New England, provides natural gas distribution services to more
than 300,000 customers in Massachusetts, New Hampshire and Maine.

8. PURCHASE OF TPC CORPORATION

     On April 1, 1999, NiSource acquired the stock of TPC Corporation (now
renamed EnergyUSA-TPC Corp. (TPC)), a Houston-based natural gas marketing and
storage company, for approximately $150 million in cash. The acquisition was
accounted for as a purchase, with the purchase price allocated to the assets and
liabilities acquired based on their estimated fair values. As a result of the
TPC acquisition, NiSource had an indirect investment in the amount of $126.0
million, representing a 77.3% interest in Market Hub Partners,

                                       36

L.P. (MHP). During the fourth quarter of 1999, subsidiaries of NiSource
purchased the remaining interests in MHP.

9. CORPORATE PREMIUM INCOME EQUITY SECURITIES AND COMPANY-OBLIGATED MANDATORILY
   REDEEMABLE PREFERRED SECURITIES OF TRUST HOLDING SOLELY COMPANY DEBENTURES

     In February 1999 NiSource completed an underwritten public offering of
Corporate PIES. The net proceeds of approximately $334.7 million were primarily
used to fund the cash portion of the consideration payable in the acquisition of
BSG, and to repay short-term indebtedness.

     The Corporate PIES were offered as one unit comprised of two separable
instruments. The first component consists of stock purchase contracts to
purchase, four years from the date of issuance, common shares at a face value of
$50. The second component consists of mandatorily redeemable preferred
securities(Preferred Securities) which represent an undivided beneficial
ownership interest in the assets of NIPSCO Capital Trust I (Capital Trust). The
Preferred Securities have a stated liquidation amount of $50. The sole assets of
Capital Trust are subordinated debentures (Debentures) of Capital Markets that
earn interest at the same rates as the Preferred Securities to which they
relate, and certain rights under related guarantees by Capital Markets. The
Preferred Securities have been pledged to secure the holders' obligation to
purchase common shares under the stock purchase contracts.

     The face value of the stock purchase contracts is not recorded in the
Consolidated Balance Sheet. A $22.2 million present value contract fee payable
to the stock purchase contract holders has been recorded as a liability and as
reduction to paid-in capital. In addition, paid-in capital has been reduced by
$10.4 million for the issuance costs of the stock purchase contracts.

     The distributions paid on Preferred Securities are presented under the
caption "minority interests" in NiSource's Consolidated Statement of Income. The
amounts outstanding are presented under the caption, "Company-obligated
mandatorily redeemable preferred securities of subsidiary trust holding solely
company debentures," in NiSource's Consolidated Balance Sheet. At December 31,
1999, there were 6.9 million 5.9% Preferred Securities outstanding with Capital
Trust assets of $345 million.

10. EQUITY FORWARD SHARE PURCHASE CONTRACT

     During the second quarter of 1999, a forward purchase contract was entered
into covering the purchase of up to 5% of NiSource's outstanding common shares.
At the end of each quarterly period during the term of the forward purchase
contract, NiSource has the option, but not the obligation, to settle the forward
purchase contract with respect to all or a portion of the common shares held by
the counterparty. As of December 31, 1999, the counterparty informed NiSource
that approximately 5.6 million shares had been purchased at a weighted average
cost of $26.90 per share. NiSource has the option to settle with the
counterparty by means of physical, net cash or net share settlement. On a
quarterly basis, NiSource will pay the counterparty a fee based on the amount
paid for common shares purchased by the counterparty, and the counterparty will
remit dividends received on shares owned. All such amounts paid and remitted
under the contract are reflected in equity contract costs of common
shareholders' equity. The net amount was a charge of $658,128 for the year
ending December 31, 1999.

     NiSource will be obligated to settle the forward purchase contract with
respect to all the remaining common shares in May 2003, or under certain
circumstances after an extension period of up to six months, at NiSource's
option. as of December 31, 1999, the nominal amount and fair value of the equity
forward purchase contract was approximately $150 million and $100 million,
respectively.

11. ACQUISITION OF COLUMBIA ENERGY GROUP

     On February 28, 2000, after completion of the bidding process initiated by
CEG, NiSource and CEG announced approval of a merger agreement under which
NiSource will form a new holding company, which will acquire all of the
outstanding shares of CEG valued at approximately $6 billion. The new holding

<PAGE>   38

company will also assume approximately $2.5 billion of CEG debt. Under the
agreement, CEG shareholders have the option to receive new holding company stock
for up to 30% of the outstanding CEG shares. Under the common stock option, each
CEG share will be exchanged for $74 in new holding company stock, based on the
average NiSource share price prior to the closing, but not more than 4.4848
shares of new holding company stock for each CEG share. Under the cash option,
each CEG share will be exchanged for $70 in cash plus a $2.60 face value unit
(consisting of a zero coupon debt security with a forward equity contract). A
commitment letter was accepted under which certain financial institutions
agreed, under specified conditions, to provide up to $6.0 billion to finance the
acquisition of CEG. The merger is conditioned upon, among other things, the
approvals of the shareholders of both companies and various regulatory
commissions. If NiSource shareholder approval is not obtained, the merger
agreement provides that the transaction will automatically be restructured to
eliminate the 30% common stock option for CEG shareholders.

or any adjournment thereof, or entitled to receive payment of any dividend or
other distribution or allotment of any rights, or entitled to exercise any

<PAGE>   4



than 60 nor less than 10 days before the date of such meeting or any other
action requiring a determination by shareholders.

     (b)  If a record date has not been fixed as provided in preceding
subsection (a), then:

          (i) The record date for determining shareholders entitled to notice of
or to vote at a meeting of shareholders shall be at the close of business on the
day next preceding the day on which notice is given, or, if notice is waived, at
the close of business on the day next preceding the day on which the meeting is
held; and

          (ii) The record date for determining shareholders for any other
purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto.

     (c)  Only those who shall be shareholders of record on the record date so

meeting and any adjournment thereof, or to receive payment of such dividend or
other distribution, or to receive such allotment of rights, or to exercise such
rights, as the case may be, notwithstanding the transfer of any shares on the
books of the Corporation after the applicable record date; provided, however,
the Corporation shall fix a new record date if a meeting is adjourned to a date
more than 120 days after the date originally fixed for the meeting.

     SECTION 2.6. Quorum and Adjournment. The holders of a majority of all the
capital shares issued and outstanding and entitled to vote at any meeting of the
shareholders, represented by the holders thereof in person or by proxy, shall be
requisite at all meetings of the shareholders to constitute a quorum for the
election of Directors or for the transaction of other business, unless otherwise
provided by law or by

                                        3

<PAGE>   5


the Corporation's Articles of Incorporation, as amended (the "Articles of
Incorporation"). Whether or not there is such a quorum, the chairman of the
meeting or the shareholders present or represented by proxy representing a
majority of the shares present or represented may adjourn the meeting from time
to time without notice other than an announcement at the meeting. At such
adjourned meeting at which the requisite number of voting shares shall be
present or represented, any business may be transacted which might have been
transacted at the meeting originally called.

     SECTION 2.7. Voting by Shareholders; Proxies. Every shareholder shall have
the right at every shareholders' meeting to one vote for each share standing in
his name on the books of the Corporation, except as otherwise provided by law or
by the Articles of Incorporation, and except that no share shall be voted at any
meeting upon which any installment is due and unpaid, or which belongs to the
Corporation. Election of directors at all meetings of the shareholders at which
directors are to be elected shall be by ballot, and a plurality of the votes
cast thereat shall be necessary to elect any director. If a quorum exists,
action on a matter (other than the election of directors) submitted to
shareholders entitled to vote thereon at any meeting shall be approved if the
votes cast favoring the action exceed the votes cast opposing the action, unless
a greater number of affirmative votes is required by law or by the Articles of
Incorporation. Each shareholder entitled to vote at a meeting of shareholders
may authorize another person or persons to act for such shareholder by proxy,
but no proxy shall be valid after eleven months from the date of its execution
unless a longer time is expressly provided therein. Without limiting the manner
in which a shareholder may authorize a person or persons to act for such
shareholder as proxy pursuant to the foregoing sentence, a shareholder may
validly grant such authority (i) by executing a writing authorizing another
person or persons to act for such shareholder as proxy or (ii) by authorizing
another person or persons to act for such shareholder as proxy by transmitting
or authorizing the transmission of a telegram, cablegram, or other means of
electronic submission to the person who will be the holder of the proxy or to a
proxy solicitation

                                        4

<PAGE>   6



firm, proxy support service organization or similar agency duly authorized by
the person who will be the holder of the proxy to receive the submission,
provided that any such telegram, cablegram or other means of electronic
submission must either contain or be accompanied by information from which it
can be determined that the telegram, cablegram or other electronic submission
was transmitted by or authorized by the shareholder, or by any other method
allowed under the Indiana Business Corporation Law. All voting at meetings of
shareholders shall be by ballot, except that the presiding officer of the
meeting may call for a viva voce vote on any matter other than the election of
directors, unless the holder or holders of ten percent (10%) or more of the
shares entitled to vote demands or demand a vote by ballot.

     SECTION 2.8. List of Shareholders. The Secretary shall make, or cause the
agent having charge of the stock transfer books of the Corporation to make, at
least five (5) days before each meeting of shareholders, a complete list of the
shareholders entitled by the Articles of Incorporation to vote at said meeting,
arranged in alphabetical order, with the address and number of shares so
entitled to vote held by each, which list shall be on file at the principal
business office of the Corporation and subject to inspection by any shareholder
within the usual business hours during said five (5) days either at the
principal business office of the corporation or a place in the city where the
meeting is to be held, which place shall be specified in the notice of meeting,
or, if not so specified, at the place where said meeting is to be held. Such
list shall be produced and kept open at the time and place of the meeting and
subject to the inspection of any shareholder during the holding of such meeting.

     SECTION 2.9. Conduct of Business. (a) Presiding Officer. The Chairman, when
present, and in the absence of the Chairman the President, shall be the

annual meeting if (A) with respect to annual meetings of shareholders subsequent
to the 1994 annual meeting of shareholders, the Corporation shall not have set

Directors or (B) by any shareholder of the Corporation who is a shareholder of

at the meeting and who complies with the notice procedures set forth in this
Section 2.9. Nominations by shareholders of persons for election to the Board of
Directors may be made at such a special meeting of shareholders if a
shareholder's notice containing the information set forth in paragraph (b)(ii)
of this Section 2.9 shall be delivered to the Secretary at the principal
executive offices of the Corporation not later than the 150th day prior to such
Special Meeting or the 10th day following the date on which public announcement
is first made of the date of the special meeting and of the nominees proposed by
the Board of Directors to be elected at such meeting.

     (d)  General. (i) Only such persons who are nominated in accordance with

set forth in this Section 2.9. The presiding officer at the meeting shall have
the power and duty to determine whether a nomination or any business proposed to
be brought before the meeting was made in accordance with the procedures set

compliance with this Section 2.9, to declare that such defective proposal shall
be disregarded.

officer or officers of the Corporation for assistance, shall make all necessary
and appropriate arrangements for all meetings of shareholders, receive all
proxies and ascertain and report to each meeting of shareholders the number of
shares present, in person and by proxy. In the absence of the Secretary, the
Assistant Secretary shall perform the foregoing duties. The certificate and
report of the Secretary or Assistant Secretary, as to the regularity of such
proxies and as to the number of shares present, in person and by proxy, shall be
received as prima facie evidence of the number of shares present in person and
by proxy for the purpose of establishing the presence of a quorum at such
meeting and for organizing the same, and for all other purposes.

     SECTION 2.11. Inspectors. At every meeting of shareholders it shall be the
duty of the presiding officer to appoint three (3) shareholders of the

shareholders. Each inspector shall take an oath to fairly and impartially
perform the duties of a inspector of the election and to honestly and truly
report the results thereof. Such inspectors shall be responsible for tallying
and certifying the vote taken on any matter at each meeting which is required to
be tallied and certified by them in the resolution of the Board of Directors
appointing them or the appointment of the presiding officer at such meeting as
the case may be. Except as otherwise provided by these By-Laws or by law, such
inspectors shall also decide all questions touching upon the qualification of
voters, the validity of proxies and ballots, and the acceptance and rejection of
votes. The Board of Directors shall have the authority to make rules
establishing presumptions as to the validity and sufficiency of proxies.

     SECTION 6.1. Contracts, Deeds and Other Instruments. All agreements
evidencing obligations of the Corporation, including but not limited to
contracts, trust deeds, promissory notes, sight drafts, time drafts and letters
of credit (including applications therefor), may be signed by any one of the
Chairman, the President, any Vice President, the Treasurer, any Assistant
Treasurer, the Secretary, any Assistant Secretary, any other person authorized
by a resolution of the Board of Directors, and any other person authorized by
the Chairman, as evidenced by a written instrument of delegation. Any such
authorization by the Board of Directors or the Chairman shall remain in effect
until rescinded by action of the Board of Directors or (in the case of a
delegation by the Chairman) by the Chairman and, where it identifies the
authorized signatory by office rather than by name, shall not be rescinded
solely by virtue of a change in the person holding that office or a temporary
vacancy in that office.

     A certified copy of these By-Laws and/or any authorization given hereunder
may be furnished as evidence of the authorities herein granted, and all persons
shall be entitled to rely on such authorities in the case of a specific
contract, conveyance or other transaction without the need of a resolution of
the Board of Directors specifically authorizing the transaction involved.

     SECTION 6.2. Checks. Checks and other negotiable instruments for the
disbursement of Corporation funds may be signed by any one of the Chairman, the
President, any Vice President, the Treasurer, the Controller and the Secretary
in such manner as shall from time to time be determined by resolution of the
Board of Directors. Electronic or wire transfers to funds may be authorized by
any officer of the Corporation who is authorized pursuant to this Section 6.2 to
disburse Corporation funds by check or other negotiable instrument.

     SECTION 6.3. Deposits. Securities, notes and other evidences of
indebtedness shall be kept in such places, and deposits of checks, drafts and
funds shall be made in such banks, trust companies or depositories, as shall be
recommended and approved by any two of the Chairman, the President, any Vice
President and the Treasurer.

     SECTION 6.4. Voting of Stock. Unless otherwise ordered by the Board of
Directors, the Chairman, the President or any Vice President shall have the
power to execute and deliver on behalf of the Corporation proxies on stock owned
by the Corporation appointing a person or persons to represent and vote such
stock at any meeting of stockholders, with full power of substitution, and shall
have power to alter or rescind such appointment. Unless otherwise ordered by the
Board of Directors, the Chairman, the President or any Vice President shall have
the power on behalf of the Corporation to attend and to act and vote at any
meeting of stockholders of any corporation in which the Corporation holds stock
and shall possess and may exercise any and all rights and powers incident to the
ownership of such stock, which, as the owner thereof, the Corporation might have
possessed and exercised if present. The Board may confer like powers upon any
other person or persons.

     SECTION 6.5. Transfer of Stock. Such form of transfer or assignment
customary or necessary to effect a transfer of stocks or other securities
standing in the name of the Corporation shall be signed by the Chairman, the
President, any Vice President or the Treasurer, and the Secretary or an
Assistant Secretary shall sign as witness if required on the form. A corporation
or person transferring any such stocks or other securities pursuant to a form of
transfer or assignment so executed shall be fully protected and shall be under
no duty to inquire whether the Board of Directors has taken action in respect
thereof.

                                  ARTICLE VII.
                     SHARE CERTIFICATES AND THEIR TRANSFER.

     SECTION 7.1. Share Certificates. Certificates for shares of the Corporation
shall be signed by the Chairman, the President or any Vice President, and by the
Secretary or any Assistant Secretary, and shall not be valid unless so signed.
Such certificates shall be appropriately numbered and contain the name of the
registered holder, the number of shares and the date of issue. If such
certificate is countersigned (a) by a transfer agent other than the Corporation
or its employee, or (b) by a registrar other than the Corporation or its
employee, any other signature on the certificate may be a facsimile.

     In case any officer, transfer agent, or registrar who has signed or whose
facsimile signature has been placed upon a certificate shall have ceased to be
such officer, transfer agent, or registrar before such certificate is issued, it
may be issued by the Corporation with the same effect as if he, she or it were
such officer, transfer agent, or registrar at the date of issue.

     SECTION 7.2. Transfer of Shares. Upon surrender to the Corporation or a
transfer agent of the Corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignment or authority to
transfer, it shall be the duty of the Corporation and such transfer agent to
issue a new certificate to the person entitled thereto, cancel the old
certificate and record the transaction. No certificate shall be issued in
exchange for any certificate until the former certificate for the same number of
shares of the same class and series shall have been surrendered and cancelled,
except as provided in Section 7.4.

     SECTION 7.3. Regulations. The Board of Directors shall have authority to
make rules and regulations concerning the issue, transfer and registration of
certificates for shares of the Corporation.

                                       21

<PAGE>   23


     SECTION 7.4. Lost, Stolen and Destroyed Certificates. The Corporation may
issue a new certificate or certificates for shares in place of any issued
certificate alleged to have been lost, stolen or destroyed upon such terms and
conditions as the Board of Directors may prescribe.

     SECTION 7.5. Registered Shareholders. The Corporation shall be entitled to
treat the holder of record (according to the books of the Corporation) of any
share or shares as the holder in fact thereof and shall not be bound to
recognize any equitable or other claim to or interest in such share or shares on
the part of any other party whether or not the Corporation shall have express or
other notice thereof, except as expressly provided by law.

     SECTION 7.6. Transfer Agents and Registrars. The Board of Directors may
from time to time appoint a transfer agent and a registrar in one or more
cities, may require all certificates evidencing shares of the Corporation to
bear the signatures of a transfer agent and a registrar, may provide that such
certificates shall be transferable in more than one city, and may provide for
the functions of transfer agent and registrar to be combined in one agency.

                                  ARTICLE VIII.
                                INDEMNIFICATION.

     SECTION 8.1. Litigation Brought by Third Parties. The Corporation shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative, formal or informal (other than
an action by or in the right of the Corporation) (an "Action") by reasons of the
fact that he or she is or

                                       22

<PAGE>   24



was a director, officer, employee or agent of the Corporation (a "Corporate
Person"), or is or was serving at the request of the Corporation as a director,
officer, employee, agent, partner, trustee or member or in another authorized
capacity (collectively, an "Authorized Capacity") of or for another corporation,
unincorporated association, business trust, partnership, joint venture, trust,
individual or other legal entity, whether or not organized or formed for profit
(collectively, "Another Entity"), against expenses (including attorneys' fees),
judgments, penalties, fines and amounts paid in settlement actually and
reasonably incurred by him or her in connection with such Action ("Expenses") if
he or she acted in good faith and in a manner he or she reasonably believed to
be in or not opposed to the best interests of the Corporation, and, with respect
to any criminal action or proceeding, had no reasonable cause to believe his or
her conduct was unlawful. The termination of any Action by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which he or she reasonably believed to be in or not
opposed to the best interests of the Corporation, or, with respect to any
criminal action or proceeding, that the person had reasonable cause to believe
his or her conduct was unlawful.

     SECTION 8.2. Litigation by or in the Right of the Corporation. The
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any action by or in the right of the Corporation to procure a
judgment in its favor by reason of the fact that he or she is or was a Corporate
Person, or is or was serving at the request of the Corporation in an Authorized
Capacity of or for Another Entity against Expenses actually and reasonably
incurred by him or her in connection with that defense or settlement of such
action if he or she acted in good faith and in a manner he or she reasonably
believed to be in or not opposed to the best interests of the Corporation,
except that no indemnification shall be made in respect of any claim, issue or
matter as to which such person shall have been adjudged to be liable for willful
negligence or misconduct in the performance of his duty to the Corporation
unless and only

                                       23

<PAGE>   25



to the extent that a court of equity or the court in which such action was
pending shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which such court
of equity or other court shall deem proper.

     SECTION 8.3. Successful Defense. To the extent that a person who is or was
a Corporate Person or is or was serving in an Authorized Capacity of Another
Entity at the request of the Corporation and has been successful on the merits
or otherwise in defense of any action, referred to in Section 8.1 or 8.2 of this
Article, or in defense of any claim, issue or matter therein, he or she shall be
indemnified against Expenses actually and reasonably incurred by him or her in
connection therewith.

     SECTION 8.4. Determination of Conduct. Any indemnification under Section
8.1 or 8.2 of this Article (unless ordered by a court) shall be made by the
Corporation only upon a determination that indemnification of the person is
proper in the circumstances because he or she has met the applicable standard of
conduct set forth in said Section 8.1 or 8.2. Such determination shall be made
(a) by the Board of Directors by a majority vote of a quorum consisting of
directors not at the time parties to such action, suit or proceeding, or (b) if
a quorum cannot be obtained, by a majority vote of a committee duly designated
by the Board of Directors (in which designation directors who are parties may
participate) consisting of two or more directors not at the time parties to such
action, suit or proceeding, or (c) by special legal counsel, or (d) by the
shareholders; provided, however, that shares owned by or voted under the control
of persons who are at the time parties to such action, suit or proceeding may
not be voted on the determination.

     SECTION 8.5. Advance Payment. The Corporation shall advance Expenses
reasonably incurred by any Corporate Person in any Action in advance of the
final disposition thereof upon the undertaking of

                                       24

<PAGE>   26



such party to repay the advance unless it is ultimately determined that such
party is entitled to indemnification hereunder, if (a) the indemnitee furnishes
the Corporation a written affirmation of his or her good faith belief that he or
she has satisfied the standard of conduct in Section 8.1 or 8.2 and (b) a
determination is made by those making the decision pursuant to Section 8.4 that
the facts then known would not preclude indemnification under these By-Laws.

     SECTION 8.6. By-Law Not Exclusive. The indemnification provided by this
Article 8 shall not be deemed exclusive of any other rights to which any person
may be entitled under any by-law, agreement, vote of shareholders or
disinterested directors, or otherwise, both as to action in his or her official
capacity and as to action in another capacity while holding such office, and
shall continue as to a person who has ceased to be a director, officer, employee
or agent and shall inure to the benefit of the heirs, executors and
administrators of such a person.

     SECTION 8.7. Insurance. The Corporation may purchase and maintain insurance
on behalf of any person who is or was a Corporate Person or is or was serving at
the request of the Corporation in an Authorized Capacity of or for Another
Entity against any liability asserted against him or her and incurred by him or
her in any such capacity, or arising out of his or her status as such, whether
or not the Corporation would have the power to indemnify him or her against such
liability under the provisions of this Article 8 or the Indiana Business
Corporation Law.

     SECTION 8.8. Effect of Invalidity. The invalidity or unenforceability of
any provision of this Article 8 shall not affect the validity or enforceability
of the remaining provisions of this Article 8.



                                       25

<PAGE>   27



     SECTION 8.9.  Definition of Corporation. For purposes of this Article 8,
references to "the Corporation" shall include, in addition to the surviving or
resulting corporation, any constituent corporation (including any constituent of
a constituent) absorbed in a consolidation or merger.

     SECTION 8.10. Change in Law. Notwithstanding the foregoing provisions of
Article 8, the Corporation shall indemnify any person who is or was a Corporate
Person or is or was serving at the request of the Corporation in an Authorized
Capacity of or for Another Entity to the full extent permitted by the Indiana
Business Corporation Law or by any other applicable law, as may from time to
time be in effect.



                                   ARTICLE IX.
                                     GENERAL.

     SECTION 9.1.  Fiscal Year. The fiscal year of the Corporation shall begin
on the 1st day of January and end on the 31st day of December in each year.

in whole or in part, and new By-Laws may be adopted, at any annual, regular or
special meeting of the Board of Directors by the affirmative vote of a majority
of a quorum of the Board of Directors.


                                       26

<PAGE>   28



     SECTION 9.4. Dividends. Subject to any provisions of any applicable statute
or of the Articles of Incorporation, dividends may be declared upon the capital
stock of the Corporation by the Board of Directors at any regular or special
meeting thereof; and such dividends may be paid in cash, property or shares of
the Corporation.

     SECTION 9.5. Control Shares. The Terms "control shares" and "control share
acquisition" used in this Section 9.5 shall have the meanings set forth in
Indiana Business Corporation Law Section 23-1-42-1, et seq. (the "Act"). Control
shares of the Corporation acquired in a control share acquisition shall have
only such voting rights as are conferred by the Act.

     Control shares of the Corporation acquired in a control share acquisition
with respect to which the acquiring person has not filed with the Corporation
the Statement required by the Act may, at any time during the period ending
sixty days after the last acquisition of control shares by the acquiring person,
be redeemed by the Corporation at the fair value thereof pursuant to procedures
authorized by a resolution of the Board of Directors. Such authority may be
exercised generally or confined to specific instances.

     Control shares of the Corporation acquired in a control share acquisition
with respect to which the acquiring person was not granted full voting rights by
the shareholders as provided in the Act may, at any time after the shareholder
vote required by the Act, be redeemed by the Corporation at the fair value
thereof pursuant to procedures authorized by a resolution of the Board of
Directors. Such authority may be exercised generally or confined to specific
instances.

to this Declaration.

     WHEREAS, the Trustees and the Sponsor established NIPSCO Capital Trust I

incidental thereto; and

     WHEREAS, the parties hereto, by this Declaration, amend and restate each
and every term and provision of the Original Declaration.

     NOW, THEREFORE, it being the intention of the parties hereto to continue
the Trust as a business trust under the Business Trust Act and that this
Declaration constitute the governing instrument of such business trust, the
Trustees hereby declare that all assets contributed to the Trust be held in
trust for the benefit of the Holders, from time to time, of the Securities
representing undivided beneficial ownership interests in the assets of the Trust
issued hereunder, subject to the provisions of this Declaration.

For purposes of this definition, the "prevailing rating" of the Remarketed

Securities of any such Trust Enforcement Event with respect to the Common
Securities for all purposes of this Declaration without any further act, vote or
consent of the Holders of the Common Securities. The foregoing provisions of

          federal income tax purposes;

          (a) The legal title to the Debentures shall be owned by and held of
record in the name of the Property Trustee in trust for the benefit of the Trust
and the Holders of the Securities. The right, title and interest of the Property
Trustee to the Debentures shall vest automatically in each Person that hereafter
may be appointed as Property Trustee in accordance with Section 6.6. Such
vesting and cessation of title shall be effective whether or not conveyancing
documents with regard to the Debentures have been executed and delivered.

          (b) The Property Trustee shall not transfer its right, title and
interest in the Debentures to the Regular Trustees nor to the Delaware Trustee
(if the Property Trustee does not also act as Delaware Trustee).

          (c) The Property Trustee shall:

               (i) establish and maintain the Property Account in the name of
          and under the exclusive control of the Property Trustee on behalf of
          the Holders of the Securities and, upon the receipt of payments of
          funds made in respect of the Debentures, deposit such funds into the
          Property Account and make payments to the Holders of the Securities
          from the Property Account in accordance with Section 7.2 (funds in the
          Property Account to be held uninvested until disbursed in accordance
          with this Declaration);

               (ii) engage in such ministerial activities as shall be necessary
          or appropriate to effect the redemption of the Securities to the
          extent the Debentures are redeemed or mature; and

               (iii) upon written direction by the Sponsor to dissolve the
          Trust, to engage in such ministerial activities as shall be necessary
          or appropriate to effect the distribution of the Debentures to the
          Holders of the Securities in exchange for the Securities.

          (d) The Property Trustee shall take all actions and perform such
duties as may be specifically required of the Property Trustee pursuant to the
terms of this Declaration and the Securities.

          (e) The Property Trustee shall take any Legal Action that arises out
of or in connection with (i) a Trust Enforcement Event of which a Responsible
Officer of the Property Trustee has actual knowledge or (ii) the Property
Trustee's duties and obligations under this Declaration or the Trust Indenture
Act; provided that if a Trust Enforcement Event has occurred and is continuing
and such event is attributable to the failure of the Debenture Issuer to pay
interest or principal on the Debentures on the date such interest or principal
is otherwise payable (or in the case of redemption, on the redemption date),
then a Holder of Preferred Securities may institute a proceeding directly
against the Debenture Issuer to enforce payment to such Holder of the principal
or interest on Debentures having an aggregate principal amount equal to the
aggregate liquidation amount of the Preferred Securities of such Holder (a
"Direct Action").

          (f) The Property Trustee shall continue to serve as a Trustee until
either:

               (i) the Trust has been completely liquidated and the proceeds of
          the liquidation have been distributed to the Holders of the Securities
          pursuant to the terms of the Securities; or


                                       18

<PAGE>   26





               (ii) a Successor Property Trustee has been appointed and has
          accepted that appointment in accordance with Section 6.6.

          (g) The Property Trustee shall have the legal power to exercise all of
the rights, powers and privileges of a holder of Debentures under the Indenture
and, if a Trust Enforcement Event actually known to a Responsible Officer of the
Property Trustee occurs and is continuing, the Property Trustee shall enforce,
for the benefit of the Holders of the Securities, its rights as holder of the
Debentures subject to the rights of the Holders of the Securities pursuant to
the terms of the Securities.

          (h) The Property Trustee may authorize one or more Persons (each, a
"Paying Agent") to pay Distributions, redemption payments or liquidation
payments on behalf of the Trust with respect to all Securities, and any such
Paying Agent shall comply with Section 317(b) of the Trust Indenture Act. Any
Paying Agent may be removed by the Property Trustee at any time, and a successor
Paying Agent or additional Paying Agents may be appointed at any time by the
Property Trustee.

          (i) Subject to this Section 3.8, the Property Trustee shall have none
of the duties, liabilities, powers or the authority of the Regular Trustees set
forth in Section 3.6.

          The Property Trustee shall exercise the powers set forth in this
Section 3.8 in a manner that is consistent with the purposes and functions of
the Trust set out in Section 3.3, and the Property Trustee shall have no power
to, and shall not, take any action that is inconsistent with the purposes and
functions of the Trust set out in Section 3.3.

     SECTION 3.9 Certain Duties and Responsibilities of the Property Trustee.

          (a) The Property Trustee, before the occurrence of any Trust
Enforcement Event and after the cure or waiver of all Trust Enforcement Events
that may have occurred, shall undertake to perform only such duties as are
specifically set forth in this Declaration, and no implied covenants shall be
read into this Declaration against the Property Trustee. If a Trust Enforcement
Event has occurred (that has not been cured or waived pursuant to Section 2.6)
of which a Responsible Officer of the Property Trustee has actual knowledge, the
Property Trustee shall exercise such of the rights and powers vested in it by
this Declaration and shall use the same degree of care and skill in its exercise
as a prudent person would exercise or use under the circumstances in the conduct
of his or her own affairs.

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

               (i) prior to the occurrence of a Trust Enforcement Event and
          after the cure or waiver of all such Trust Enforcement Events that may
          have occurred:

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

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

               (ii) the Property Trustee shall not be liable for any error of
          judgment made in good faith by a Responsible Officer of the Property
          Trustee, unless it has been proven that the Property Trustee was
          negligent in ascertaining the pertinent facts;

               (iii) the Property Trustee shall not be liable with respect to
          any action taken or omitted to be taken by it without negligence, in
          good faith in accordance with the direction of the Holders of not less
          than a Majority in Liquidation Amount of the Securities relating to
          the time, method and place of conducting any proceeding for any remedy
          available to the Property Trustee, or exercising any trust or power
          conferred upon the Property Trustee under this Declaration;

               (iv) no provision of this Declaration shall require the Property
          Trustee to expend or risk its own funds or otherwise incur personal
          financial liability in the performance of any of its duties or in the
          exercise of any of its rights or powers, if it has reasonable grounds
          for believing that the repayment of such funds or liability is not
          reasonably assured to it under the terms of this Declaration or
          indemnity reasonably satisfactory to the Property Trustee against such
          risk or liability is not reasonably assured to it;

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

               (vi) the Property Trustee shall have no duty or liability for or
          with respect to the value, genuineness, existence or sufficiency of
          the Debentures or the payment of any taxes or assessments levied
          thereon or in connection therewith;

               (vii) the Property Trustee shall not be liable for any interest
          on any money received by it except as it otherwise may agree with the
          Sponsor, and money held by the Property Trustee need not be segregated
          from other funds held by it except in relation to the Property Account
          maintained by the Property Trustee pursuant to Section 3.8(c)(i) and
          except to the extent otherwise required by law; and

               (viii) the Property Trustee shall not be responsible for
          monitoring the compliance by the Regular Trustees or the Sponsor with
          their respective duties under this Declaration, nor shall the Property
          Trustee be liable for any default or misconduct of the Regular
          Trustees or the Sponsor.

          certificate, statement, instrument, opinion, report, notice, request,
          direction, consent, order, bond, debenture, note, other evidence of
          indebtedness or other paper or document believed by it to be genuine

               (ii) Any direction or act of the Sponsor contemplated by this
          Declaration shall be sufficiently evidenced by an Officers'
          Certificate.

               (iii) Whenever in the administration of this Declaration, the
          Property Trustee shall deem it desirable that a matter be proved or
          established before taking, suffering or omitting any action hereunder,
          the Property Trustee (unless other evidence is herein specifically
          prescribed) may request, in the absence of bad faith on its part, and
          conclusively rely upon an Officers' Certificate which, upon receipt of
          such request, shall be promptly delivered by the Sponsor.

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

               (v) The Property Trustee may consult with counsel of its choice

          exercise any of the rights or powers vested in it by this Declaration
          at the request or direction of any Holder of Securities, unless such
          Holder of Securities has provided to the Property Trustee security and
          indemnity, reasonably satisfactory to the Property Trustee, against
          the costs, expenses (including attorneys' fees and expenses and the
          expenses of the Property Trustee's agents, nominees or custodians) and
          liabilities that might be incurred by it in complying with such
          request or direction, including such reasonable advances as may be
          requested by the Property Trustee; provided that nothing contained in
          this Section 3.10(a) shall be taken to relieve the Property Trustee,
          upon the occurrence of an Indenture Event of Default, of its
          obligation to exercise the rights and powers vested in it by this
          Declaration.

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

               (ix) Any action taken by the Property Trustee or its agents
          hereunder shall bind the Trust and the Holders of the Securities, and
          the signature of the Property Trustee or its agents alone shall be
          sufficient and effective to perform any such action, and no third
          party shall be required to inquire as to the authority of the Property
          Trustee to so act or as to its compliance with any of the terms and
          provisions of this Declaration, both of which shall be evidenced
          conclusively by the Property Trustee's or its agent's taking such
          action.

               (x) Whenever in the administration of this Declaration the
          Property Trustee shall deem it desirable to receive instructions with
          respect to enforcing any remedy or right or taking any other action
          hereunder, the Property Trustee (A) may request instructions from the
          Holders of the Securities, which instructions only may be given by the
          Holders of the same proportion in liquidation amount of the Securities
          as would be entitled to direct the Property Trustee under the terms of
          the Securities in respect of such remedy, right or action, (B) may
          refrain from enforcing such remedy or right or taking such other
          action until such instructions are received and (C) shall be protected
          in conclusively relying on or acting in accordance with such
          instructions.

               (xi) Except as otherwise expressly provided by this Declaration,
          the Property Trustee shall not be under any obligation to take any
          action that is discretionary under the provisions of this Declaration.

               (xii) The Property Trustee shall not be liable for any action
          taken, suffered or omitted to be taken by it without negligence, in
          good faith and reasonably believed by it to be authorized or within
          the discretion, rights or powers conferred upon it by this
          Declaration.

          (b) No provision of this Declaration shall be deemed to impose any
duty or obligation on the Property Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it, in any
jurisdiction in which it shall be illegal, or in which the Property Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts, or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Property Trustee
shall be construed to be a duty.

     SECTION 3.11 Delaware Trustee.

          Notwithstanding any other provision of this Declaration other than
Section 6.2, the Delaware Trustee shall not be entitled to exercise any powers
of, nor shall the Delaware Trustee have any of the duties and responsibilities
of, the Regular Trustees or the Property Trustee described in this Declaration.
Except as set forth in Section 6.2, the Delaware Trustee shall be a Trustee for
the sole and limited purpose of fulfilling the requirements of Section 3807 of
the Business Trust Act.

     SECTION 3.12 Execution of Documents.

          Except as otherwise required by the Business Trust Act or applicable
law, any Regular Trustee is authorized to execute on behalf of the Trust any
documents that the Regular Trustees have the power and authority to execute
pursuant to Section 3.6.

     SECTION 3.13 Not Responsible for Recitals or Issuance of Securities.

          The recitals contained in this Declaration and the Securities shall be
taken as the statements of the Sponsor, and the Trustees do not assume any
responsibility for their correctness. The Trustees make no representations as to
the value or condition of the property of the Trust or any part thereof. The
Trustees make no representations as to the validity or sufficiency of this
Declaration, the Securities, the Debentures or the Indenture.

     SECTION 3.14 Duration of Trust.

          The Trust shall exist until dissolved pursuant to the provisions of
Article 8 hereof.

     SECTION 3.15 Mergers.

          (a) The Trust may not consolidate with, convert into, amalgamate or
merge with or into, be replaced by or convey, transfer or lease its properties
and assets substantially as an entirety to any corporation or other body, except
as described in Section 3.15(b) and (c).

          (b) At the request of the Sponsor and with the consent of the Regular
Trustees or, if there are more than two, a majority of the Regular Trustees and
without the consent of the Holders of the Preferred Securities, the Delaware
Trustee or the Property Trustee, the Trust may consolidate with, convert into,
amalgamate or merge with or into, be replaced by or convey, transfer or lease
its properties substantially as an entirety to a trust organized as such under
the laws of any state; provided that:

               (i) if the Trust is not the successor entity, such successor
          entity (the "Successor Entity") either:

                    (A) expressly assumes all of the obligations of the Trust
               with respect to the Securities; or

                    (B) substitutes for the Securities other securities having
               substantially the same terms as the Securities (the "Successor
               Securities"), so long as such Successor Securities rank the same
               as the Securities with respect to Distributions and payments upon
               liquidation, redemption and otherwise;

               (ii) the Debenture Issuer expressly appoints a trustee of such
          Successor Entity that possesses the same powers and duties as the
          Property Trustee as the holder of the Debentures;

               (iii) the Preferred Securities or any Successor Securities are
          or, upon notification of issuance will be, listed on any national
          securities exchange or with any other or organization on which the
          Preferred Securities are then listed or quoted;





                                       23

<PAGE>   31




               (iv) such consolidation, conversion, amalgamation, merger,
          replacement, conveyance, transfer or lease does not cause the
          Preferred Securities (including any Successor Securities) to be
          downgraded by any nationally recognized statistical rating
          organization;

               (v) such consolidation, conversion, amalgamation, merger,
          replacement, conveyance, transfer or lease does not adversely affect
          the rights, preferences and privileges of the Holders of the Preferred
          Securities (including any Successor Securities) in any material
          respect;

               (vi) such Successor Entity has a purpose substantially identical
          to that of the Trust;

               (vii) prior to such consolidation, conversion, amalgamation,
          merger, replacement, conveyance, transfer or lease, the Sponsor has
          received an opinion of independent counsel to the Trust experienced in
          such matters to the effect that:

                    (A) such consolidation, conversion, amalgamation, merger,
               replacement, conveyance, transfer or lease does not adversely
               affect the rights, preferences and privileges of the Holders of
               the Securities (including any Successor Securities) in any
               material respect;

                    (B) following such consolidation, conversion, amalgamation,
               merger, replacement, conveyance, transfer or lease, neither the
               Trust nor such Successor Entity will be required to register as
               an Investment Company under the Investment Company Act; and

                    (C) following such consolidation, conversion, amalgamation
               or merger, replacement, conveyance, transfer or lease, the Trust
               (or such Successor Entity) will continue to be classified as a
               grantor trust for United States federal income tax purposes;

               (viii) the Sponsor or any permitted successor or assignee owns
          all of the Common Securities and guarantees the obligations of such
          Successor Entity under the Successor Securities, at least to the
          extent provided by the Guarantee; and

               (ix) such Successor Entity expressly assumes all of the
          obligations of the Trust.

          (c) Notwithstanding Section 3.15(b), the Trust shall not, except with
the consent of Holders of 100% in aggregate liquidation amount of the
Securities, consolidate with, convert into, amalgamate or merge with or into, be
replaced by or convey, transfer or lease its properties and assets substantially
as an entirety to, any other entity or permit any other entity to consolidate
with, amalgamate, merge with or into, or replace it, if such consolidation,
conversion, amalgamation, merger, replacement, conveyance, transfer or lease
would cause the Trust or any Successor Entity to be classified as other than a
grantor trust for United States federal income tax purposes or would cause each
Holder of Securities not to be treated as owning an undivided beneficial
ownership interest in the Debentures.

     SECTION 3.16 Property Trustee May File Proofs of Claim.

          In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
similar judicial proceeding relative to the Trust or any other obligor upon the
Securities or the property of the Trust or of such other obligor or their
creditors, the Property Trustee (irrespective of whether any Distributions on
the Securities are then due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Property Trustee has made


                                       24

<PAGE>   32

any demand on the Trust for the payment of any past due Distributions) shall be
entitled and empowered, to the fullest extent permitted by law, by intervention
in such proceeding or otherwise:

          (a) to file and prove a claim for the whole amount of any
Distributions owing and unpaid in respect of the Securities (or, if the
Securities are original issue discount securities, such portion of the
liquidation amount as may be specified in the terms of such securities) and to
file such other papers or documents as may be necessary or advisable in order to
have the claims of the Property Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Property Trustee, its
agents and counsel) and of the Holders of the Securities allowed in such
judicial proceeding; and

          (b) 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 to make such payments to the Property Trustee and, in
the event the Property Trustee consents to the making of such payments directly
to the Holders, to pay to the Property Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Property
Trustee, its agents and counsel, and any other amounts due the Property Trustee.

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

an application to the New York Stock Exchange or any other national stock

the Property Trustee and the Delaware Trustee for, and to hold each of them
harmless against, any loss, liability or expense incurred without negligence or
bad faith on the part of the Property Trustee or the Delaware Trustee, as the
case may be, arising out of or in connection with the acceptance or
administration of the trust or trusts hereunder, including the costs and
expenses of defending either of them against any claim or liability in
connection with the exercise or performance of any of their respective powers or
duties hereunder. The provisions of this Section 4.2 shall survive the
resignation or removal of the Delaware Trustee or the Property Trustee and the
termination of this Declaration.

     SECTION 5.1 Debenture Issuer's Purchase of the Common Securities.

          On the Closing Date, the Debenture Issuer shall purchase all of the
Common Securities issued by the Trust, in an aggregate liquidation amount equal
to at least three percent of the total capital of the Trust, at such time as the
Preferred Securities are sold and issued. If any additional Securities are
issued pursuant to the exercise of any Over-allotment Option, then the Debenture
Issuer shall purchase, on the date of such issuance, an additional number of
Common Securities such that the aggregate liquidation amount of the Common

<PAGE>   34




          (c) to use its commercially reasonable efforts to ensure that the
Trust will not be an Investment Company required to be registered under the
Investment Company Act; and

          (d) not to take any action that would be reasonably likely to cause
the Trust to be classified as an association or a publicly traded partnership
taxable as a corporation for United States federal income tax purposes.

          (b) if not a natural person, an entity that has its principal place of
business in the State of Delaware and otherwise meets the requirements of

          (a) Subject to Section 6.6(b), the Trustees may be appointed or
removed without cause at any time:

               (i) until the issuance of any Securities, by written instrument
          executed by the Sponsor; and

               (ii) after the issuance of any Securities, by a vote of the

          consent in lieu of such meeting.

          (b) The Property Trustee shall not be removed in accordance with
Section 6.6(a) until a successor Trustee possessing the qualifications to act as

such Successor Property Trustee and delivered to the Regular Trustees and the
Sponsor. The Delaware

<PAGE>   36




Trustee shall not be removed in accordance with Section 6.6(a) until a successor
Trustee possessing the qualifications to act as Delaware Trustee under Sections

such appointment by written instrument executed by such Successor Delaware
Trustee and delivered to the Regular Trustees and the Sponsor.

          (c) A Trustee appointed to office shall hold office until a successor
has been appointed, until death or dissolution or until removal or resignation.
Any Trustee may resign from office (without need for prior or subsequent
accounting) by written instrument executed by such Trustee and delivered to the
Sponsor and the other Trustees, which resignation shall take effect upon such
delivery or upon such later date as is specified therein; provided that:

               (i) no such resignation of the Property Trustee shall be
          effective:

                    (A) until a Successor Property Trustee has been appointed
               and has accepted such appointment by written instrument executed
               by such Successor Property Trustee and delivered to the Regular
               Trustees, the Sponsor and the resigning Property Trustee; or

                    (B) until the assets of the Trust have been completely

               the Securities; and

               (ii) no such resignation of the Delaware Trustee shall be
          effective until a Successor Delaware Trustee has been appointed and
          has accepted such appointment by written instrument executed by such
          Successor Delaware Trustee and delivered to the Regular Trustees, the
          Sponsor and the resigning Delaware Trustee.

          (d) The Holders of the Common Securities shall use their best efforts
to promptly appoint a Successor Property Trustee or Successor Delaware Trustee,
as the case may be, if the Property Trustee or the Delaware Trustee delivers an
instrument of resignation in accordance with this Section 6.6.

          (e) If no Successor Property Trustee or Successor Delaware Trustee, as
the case may be, has been appointed and accepted appointment as provided in this
Section 6.6 within 60 days after delivery of an instrument of resignation or
removal, the resigning or removed Property Trustee or Delaware Trustee, as
applicable, may petition any court of competent jurisdiction for appointment of
a Successor Property Trustee or Successor Delaware Trustee, as applicable. Such
court may thereupon, after prescribing such notice, if any, as it may deem
proper, appoint a Successor Property Trustee or Successor Delaware Trustee, as
the case may be.

          (f) No Property Trustee or Delaware Trustee shall be liable for the
acts or omissions to act of any Successor Property Trustee or Successor Delaware
Trustee, as the case may be.

     SECTION 6.7 Vacancies among Trustees.

          If a Trustee ceases to hold office for any reason and the number of
Trustees is not reduced pursuant to Section 6.1, or if the number of Trustees is
increased pursuant to Section 6.1, a vacancy shall occur. A resolution
certifying the existence of such vacancy by the Regular Trustees or, if there
are more than two, a majority of the Regular Trustees shall be conclusive
evidence of the existence of such vacancy. The vacancy shall be filled with a
Trustee appointed in accordance with Section 6.6.

<PAGE>   37




     SECTION 6.8 Effect of Vacancies.

          The death, resignation, retirement, removal, bankruptcy, dissolution,
liquidation, incompetence or incapacity to perform the duties of a Trustee shall
not operate to annul, dissolve or terminate the Trust nor to terminate this
Declaration. Whenever a vacancy in the number of Regular Trustees shall occur,
until such vacancy is filled by the appointment of a Regular Trustee in
accordance with Section 6.6, the Regular Trustees in office, regardless of their
number, shall have all the powers granted to the Regular Trustees and shall
discharge all the duties imposed upon the Regular Trustees by this Declaration.

     SECTION 6.9 Meetings.

          If there is more than one Regular Trustee, meetings of the Regular
Trustees shall be held from time to time upon the call of any Regular Trustee.

by resolution of the Regular Trustees. Notice of any in-person meetings of the
Regular Trustees shall be hand delivered or otherwise delivered in writing
(including by facsimile, with a hard copy by overnight courier) not less than 48
hours before such meeting. Notice of any telephonic meetings of the Regular
Trustees shall be hand delivered or otherwise delivered in writing (including by
facsimile, with a hard copy by overnight courier) not less than 24 hours before
a meeting. Notices shall contain a brief statement of the time, place and
anticipated purposes of the meeting. The presence (whether in person or by
telephone) of a Regular Trustee at a meeting shall constitute a waiver of notice
of such meeting except where a Regular Trustee attends a meeting for the express
purpose of objecting to the transaction of any activity on the ground that the
meeting has not been lawfully called or convened. Unless provided otherwise in
this Declaration, any action of the Regular Trustees may be taken at a meeting
by vote of a majority of the Regular Trustees present (whether in person or by
telephone) and eligible to vote with respect to such matter, provided a Quorum
is present, or without a meeting by the unanimous written consent of the Regular
Trustees. In the event there is only one Regular Trustee, any and all action of
such Regular Trustee shall be evidenced by a written consent of such Regular
Trustee.

     SECTION 6.10 Delegation of Power by the Regular Trustees.

          (a) Any Regular Trustee may delegate to any natural person over the
age of 21, by power of attorney consistent with applicable law, his, her or its
power for the purpose of executing any documents contemplated in Section 3.6.

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

     SECTION 6.11 Merger, Consolidation, Conversion or Succession to Business.

          Any entity into which the Property Trustee, the Delaware Trustee or
any Regular Trustee that is not a natural person may be merged or converted or
with which such Trustee may be consolidated, or any entity resulting from any
merger, conversion or consolidation to which such Trustee is a party, or any
entity succeeding to all or substantially all the corporate trust business of
such Trustee, shall be the successor of such Trustee hereunder, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, provided that such entity otherwise is qualified and eligible
under this Article.

                       ARTICLE 7: TERMS OF THE SECURITIES

     SECTION 7.1 General Provisions Regarding the Securities.

          (a) The Regular Trustees shall issue, on behalf of the Trust, one
class of preferred securities representing undivided beneficial ownership
interests in the assets of the Trust and one class of common securities
representing undivided beneficial ownership interests in the assets of the
Trust.

               (i) The Preferred Securities of the Trust shall have an aggregate
          stated liquidation amount with respect to the assets of the Trust of
          three hundred million dollars ($300,000,000) (subject to increase to
          not more than three hundred forty-five million dollars ($345,000,000)
          in the event of the exercise of any Over-allotment Option) and a
          stated liquidation amount with respect to the assets of the Trust of
          $50 per Preferred Security. The Preferred Securities are hereby
          designated for identification purposes only as the Preferred
          Securities. The Preferred Security Certificates shall be substantially
          in the form of Exhibit A hereto, with such changes and additions
          thereto or deletions therefrom as may be required by ordinary usage,
          custom or practice.

               (ii) The Common Securities of the Trust shall have an aggregate
          liquidation amount with respect to the assets of the Trust of nine
          million two hundred seventy-eight thousand four hundred dollars
          ($9,278,400) (subject to increase to not more than ten million seven
          hundred thousand dollars ($10,700,000) in the event of the exercise of
          any Over-allotment Option) and a liquidation amount with respect to
          the assets of the Trust of $50 per Common Security. The Common
          Securities are hereby designated for identification purposes only as
          the Common Securities (the "Common Securities"). The Common Security
          Certificates shall be substantially in the form of Exhibit B hereto,
          with such changes and additions thereto or deletions therefrom as may
          be required by ordinary usage, custom or practice.

          (b) Payment of Distributions on, and any payment of the Redemption
Price upon a redemption of, the Preferred Securities and the Common Securities,
as applicable, shall be made Pro Rata based on the liquidation amount of such
Preferred Securities and Common Securities; provided that if, on any date on
which payment of a Distribution or the Redemption Price is to be made, an
Indenture Event of Default has occurred and is continuing, then such payment
shall not be made on any of the Common Securities, and no other payment on
account of the redemption, liquidation or other acquisition of such Common
Securities shall be made, until all accumulated and unpaid Distributions, or
payments of the Redemption Price, as the case may be, on all of the outstanding
Preferred Securities for which Distributions are to be paid or that have been
called for redemption, as the case may be, are fully paid. All funds available
to the Property Trustee shall first be applied to the payment in full in cash of
all Distributions on, or the Redemption Price of, the Preferred Securities then
due and payable.

          (c) The consideration received by the Trust for the issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust.

          (d) Upon issuance of the Securities as provided in this Declaration,
the Securities so issued shall be validly issued, fully paid and non-assessable
beneficial ownership interests in the assets of the Trust.

          (e) Every Person, by virtue of having become a Holder of Securities or
a Beneficial Owner of Preferred Securities in accordance with the terms of this
Declaration, shall be deemed to have expressly



                                       31

<PAGE>   39


assented and agreed to the terms of, and shall be bound by, this Declaration,
the Guarantee, the Indenture and the Debentures.

          (f) The Holders of the Securities shall not have any preemptive or
similar rights.

          (g) The Certificates shall be signed on behalf of the Trust by a
Regular Trustee. Such signature shall be the manual or facsimile signature of
any present or any future Regular Trustee. If a Regular Trustee of the Trust who
has signed any of the Certificates ceases to be a Regular Trustee before such
signed Certificates have been delivered by the Trust, such Certificates
nevertheless may be delivered as though the Person who signed such Certificates
had not ceased to be a Regular Trustee. Any Certificate may be signed on behalf
of the Trust by such Persons who, at the actual date of execution of such
Certificate, shall be the Regular Trustees of the Trust, although at the date of
the execution and delivery of this Declaration any such Person was not such a
Regular Trustee. Certificates shall be printed, lithographed or engraved or may
be produced in any other manner as is reasonably acceptable to the Regular
Trustees, as evidenced by their execution thereof, and may have such letters,
numbers or other marks of identification or designation and such legends or
endorsements as the Regular Trustees may deem appropriate, or as may be required
to comply with any law or with any rule or regulation of any stock exchange on
which the Securities may be listed, or to conform to usage.

          A Preferred Security Certificate shall not be valid until
authenticated by the manual signature of an authorized signatory of the Property
Trustee. Such signature shall be conclusive evidence that such Preferred
Security Certificate has been authenticated under this Declaration.

          Upon a written order of the Trust signed by one Regular Trustee, the
Property Trustee shall authenticate the Preferred Security Certificates for
original issue. The aggregate number of Preferred Securities outstanding at any
time shall not exceed the aggregate stated liquidation amount set forth in
Section 7.1(a)(i).

          The Property Trustee may appoint an authenticating agent acceptable to
the Trust to authenticate Certificates. An authenticating agent may authenticate
Certificates whenever the Property Trustee may do so. Each reference in this
Declaration to authentication by the Property Trustee shall include
authentication by such agent. An authenticating agent shall have the same rights
as the Property Trustee to deal with the Sponsor or an Affiliate of the Sponsor.

          (h) Unless otherwise specified in the terms of the Preferred
Securities, the Preferred Securities Certificates, upon original issuance
(including Preferred Securities, if any, issued pursuant to the exercise of any
Over-allotment Option), shall be issued as Global Securities in the form of one
or more fully registered global Preferred Security Certificates (each a "Global
Certificate"), to be delivered to The Depository Trust Company, the initial
Depositary, by or on behalf of the Trust. Such Global Certificates initially
shall be registered on the books and records of the Trust in the name of "Cede &
Co.," the nominee of the initial Depositary. No Beneficial Owner of Preferred
Securities shall receive a definitive Preferred Security Certificate
representing such Beneficial Owner's interest in such Global Certificates,
except as provided in Section 7.12. Unless and until definitive, fully
registered Preferred Security Certificates have been issued to the Beneficial
Owners of Preferred Securities pursuant to Section 7.12,

               (i) the provisions of this Section 7.1(h) shall be in full force
          and effect;


                                       32
<PAGE>   40




               (ii) the Trust and the Trustees shall be entitled to deal with
          the Depositary for all purposes of this Declaration (including the
          payment of Distributions on the Global Certificates and receiving
          approvals, votes or consents thereunder) as the Holder of the
          Preferred Securities and the sole of holder of the Global Certificates
          and, except as set forth herein or in Rule 3a-7 (if the Trust is
          excluded from the definition of an Investment Company solely by reason
          of Rule 3a-7) with respect to the Property Trustee, shall have no
          obligation to the Beneficial Owners of the Preferred Securities;

               (iii) to the extent that the provisions of this Section 7.1(h)
          conflict with any other provisions of this Declaration, the provisions
          of this Section 7.1(h) shall control; and

               (iv) the rights of the Beneficial Owners of the Preferred
          Securities shall be exercised only through the Depositary and shall be
          limited to those established by law and agreements between such
          Beneficial Owners and the Depositary and/or the Depositary
          Participants. The Depositary shall make book-entry transfers among
          Depositary Participants and receive and transmit Distributions on the
          Global Certificates to such Depositary Participants; provided that
          solely for the purposes of determining whether the Holders of the
          requisite amount of Preferred Securities have voted on any matter
          provided for in this Declaration, so long as definitive Preferred
          Security Certificates have not been issued, the Trustees may rely
          conclusively on, and shall be protected in relying on, any written
          instrument (including a proxy) delivered to the Trustees by the
          Depositary setting forth the votes of the Beneficial Owners of the
          Preferred Securities or assigning the right to vote on any matter to
          any other Persons either in whole or in part.

          Whenever a notice or other communication to the Holder of the
Preferred Securities is required to be given under this Declaration, unless and
until definitive Preferred Security Certificates have been issued pursuant to
Section 7.1, the Trustees shall deliver all such notices and communications
specified herein to be given to the Holders of the Preferred Securities to the
Depositary, and, with respect to any Preferred Security Certificate registered
in the name of a Depositary or the nominee of a Depositary, the Trustees may
conclusively rely on, and shall be protected in relying on, any written
instrument (including a proxy) delivered to the Trustees by the Depositary
setting forth the votes of the Beneficial Owners of the Preferred Securities or
assigning the right to vote on any matter or any other Persons either in whole
or in part.

     SECTION 7.2 Distributions.

          (a) Holders of the Securities shall be entitled to receive
Distributions that shall accumulate and be payable at the rate per annum of
5.90% of the stated liquidation amount of $50 per Security until February 19,
2003, and at the Reset Rate thereafter. The amount of Distributions payable for
any period shall be computed (i) for any full quarterly distribution period, on
the basis of a 360-day year of twelve 30-day months and (ii) for any period
shorter than a full quarterly distribution period, on the basis of a 30-day
month and, for any period of less than one month, on the basis of the actual
number of days elapsed per 30-day month. Subject to Section 7.1(b),
Distributions shall be made on the Securities on a Pro Rata basis. Distributions
on the Securities shall accumulate from the date of original issue, shall be
cumulative and shall be payable quarterly, in arrears, on February 19, May 19,
August 19 and November 19 of each year, commencing May 19, 1999, when, as and if
available for payment, by the Property Trustee, except as otherwise described
below. Distributions shall be payable only to the extent that payments are made
to the Trust in respect of the Debentures held by the Property Trustee and to
the extent that the Trust has funds available for the payment of such
Distributions in the Property Account.




                                       33

<PAGE>   41




          (b) Distributions not paid on the scheduled payment date shall
accumulate and compound quarterly at the rate of 5.90% per annum through and
including February 18, 2003, and at the Reset Rate thereafter ("Compounded
Distributions"). "Distributions" shall mean ordinary cumulative distributions
together with any Compounded Distributions.

          (c) If and to the extent that the Debenture Issuer makes a payment of
principal of and any premium or interest on the Debentures held by the Property
Trustee (the amount of any such payment being a "Payment Amount"), the Property
Trustee shall and is directed, to the extent funds are available for that
purpose, to make a distribution of the Payment Amount to the Holders of the
Securities, on a Pro Rata basis, subject to Section 7.1(b).

          (d) Distributions on the Securities shall be payable to the Holders
thereof as they appear on the register of the Trust as of the close of business
on the relevant record dates. If the Preferred Securities are represented by one
or more Global Securities, the relevant record dates shall be the close of
business on the Business Day preceding each Distribution payment date, unless a
different regular record date is established or provided for the corresponding
interest payment date on the Debentures. The relevant record dates for the
Common Securities shall be the same as for the Preferred Securities. If the
Preferred Securities are not represented by one or more Global Securities, the
relevant record dates for the Preferred Securities shall be the fifteenth
Business Day prior to the Distribution payment dates, or such other dates as may
be selected by the Regular Trustees. At all times, the Distribution payment
dates shall correspond to the interest payment dates on the Debentures.
Distributions payable on any Securities that are not punctually paid on any
Distribution payment date, as a result of the Debenture Issuer having failed to
make a payment on the Debentures, shall cease to be payable to the Person in
whose name such Securities are registered on the relevant record date, and such
defaulted Distribution instead shall be payable to the Person in whose name such
Securities are registered on the special record date or other specified date
determined in accordance with the Indenture for payment of the corresponding
defaulted interest on the Debentures. If any date on which a Distribution is
payable on the Securities is not a Business Day, then payment of the
Distribution payable on such date shall be made on the next 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 calendar year, such
payment shall be made on the preceding Business Day, with the same force and
effect as if made on such payment date.

          (e) In the event that there is any money or other property held by or
for the Trust that is not accounted for hereunder, such property shall be
distributed Pro Rata among the Holders of the Securities, subject to Section
7.1(b).

     SECTION 7.3 Redemption of Securities.

          Upon the repayment or redemption, in whole or in part, of the
Debentures held by the Trust, whether at the stated maturity of the Debentures
or upon earlier redemption as provided in the Indenture, the proceeds from such
repayment or redemption shall be simultaneously applied Pro Rata (subject to
Section 7.1(b)) to redeem, at the Redemption Price, Securities having an
aggregate liquidation amount equal to the aggregate principal amount of the
Debentures so repaid or redeemed. Holders of the Securities shall be given not
less than 30 nor more than 60 days notice of such redemption in accordance with
Section 7.4.

     SECTION 7.4 Redemption Procedures.



                                       34
<PAGE>   42




          (a) Notice of any redemption of the Securities (a "Redemption
Notice"), which notice shall be irrevocable, shall be given by the Trust by mail
to each Holder of Securities to be redeemed at least 30 but no more than 60 days
before the date fixed for redemption thereof, which shall be the date fixed for
redemption of the Debentures. For purposes of the calculation of the date of
redemption and the dates on which notices are given pursuant to this Section
7.4(a), a Redemption Notice shall be deemed to be given on the day such notice
is first mailed by first-class mail, postage prepaid, to the Holders of the
Securities. Each Redemption Notice shall be addressed to the Holders of the
Securities at the address of each such Holder appearing in the register of the
Trust. No defect in the Redemption Notice or in the mailing of either thereof
with respect to any Holder shall affect the validity of the redemption
proceedings with respect to any other Holder.

          (b) Subject to the Trust's fulfillment of the notice requirements set
forth in Section 7.4(a), if Securities are to be redeemed, then (provided that
the Debenture Issuer has paid the Property Trustee a sufficient amount of cash
in connection with the related repayment or redemption of the Debentures) (i)
with respect to the Preferred Securities represented by one or more Global
Securities, by 12:00 noon, New York City time, on the redemption date, the
Property Trustee will deposit irrevocably with the Depositary or its nominee
funds sufficient to pay the applicable Redemption Price, and, subject to Section
7.4(c), the Property Trustee shall give the Depositary irrevocable instructions
and authority to pay the Redemption Price to the Beneficial Owners of the
Preferred Securities, and (ii) with respect to Securities not represented by one
or more Global Securities, subject to Section 7.4(c), the Property Trustee shall
pay the applicable Redemption Price to the Holders of such Securities by check
mailed to the address of each Holder appearing on the register of the Trust on
the redemption date. If any date fixed for redemption of Securities is not a
Business Day, then payment of the Redemption Price payable on such date shall be
made on the next Business Day (without any interest thereon), except that if
such Business Day falls in the next calendar year, such payment shall be made on
the preceding Business Day, in each case with the same force and effect as if
made on such date fixed for redemption. If payment of the Redemption Price in
respect of any Securities is improperly withheld or refused and not paid either
by the Trust or by the Sponsor as guarantor pursuant to the Guarantee, then
Distributions on such Securities shall continue to accumulate at the then
applicable rate, from the original redemption date to the actual date of
payment, in which case the actual payment date shall be the date fixed for
redemption for purposes of calculating the Redemption Price. For these purposes,
the applicable Redemption Price shall not include Distributions that are being
paid to Holders of Securities who were Holders of Securities on a relevant
record date. If a Redemption Notice has been given and funds have been deposited
or paid as required, then immediately prior to the close of business on the date
of such deposit or payment, Distributions will cease to accumulate on the
Securities called for redemption, and all rights of Holders of such Securities
so called for redemption shall cease, except the right of the Holders of such
Securities to receive the Redemption Price, but without interest on such
Redemption Price, and from and after the date fixed for redemption, such
Securities will cease to be outstanding.

          (c) If any Preferred Securities to be redeemed shall then be pledged
pursuant to the Pledge Agreement, the applicable Redemption Price for such
Preferred Securities shall be credited to the collateral account maintained by
the Collateral Agent on or prior to 12:30 p.m., New York City time, and applied
by the Securities Intermediary in accordance with Section 5.8 of the Pledge
Agreement.

          (d) Neither the Regular Trustees nor the Trust shall be required to
register or cause to be registered the transfer of any Securities that have been
called for redemption, except for the unredeemed portion of any Securities being
redeemed in part.


                                       35
<PAGE>   43



          (e) Subject to the foregoing and applicable law (including, without
limitation, United States federal securities laws), the Debenture Issuer or its
Affiliates may purchase, at any time and from time to time, outstanding
Preferred Securities by tender, in the open market or by private agreement.

     SECTION 7.5 Voting Rights of the Preferred Securities.

          (a) Except as provided under this Section 7.5 and Section 11.1 and as
otherwise required by the Business Trust Act, the Trust Indenture Act and other
applicable law, the Holders of the Preferred Securities shall have no voting
rights.

          (b) Subject to the requirement of the Property Trustee obtaining a tax
opinion in certain circumstances set forth in Section 7.5(d), the Holders of a
Majority in Liquidation Amount of the Preferred Securities, voting separately as
a class, shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Property Trustee, or to direct
the exercise of any trust or power conferred upon the Property Trustee under
this Declaration, including the right to direct the Property Trustee, as Holder
of the Debentures, to (i) exercise the remedies available to it under the
Indenture, (ii) consent to any amendment or modification of the Indenture or the
Debentures where such consent is required or (iii) waive any past default and
its consequences that are waivable under Section 513 of the Indenture; provided
that if an Indenture Event of Default has occurred and is continuing, then the
Holders of at least 25% of the aggregate stated liquidation amount of the
Preferred Securities may direct the Property Trustee to declare the principal of
and interest on the Debentures due and payable; and provided further that where
a consent or action under the Indenture would require the consent or act of the
Holders of a Supermajority of the aggregate principal amount of Debentures
affected thereby, the Property Trustee may give such consent or take such action
only at the direction of the Holders of at least the same Supermajority in
aggregate stated liquidation amount of the Preferred Securities.

          (c) If the Property Trustee fails to enforce its rights under the
Debentures after a Holder of Preferred Securities has made a written request,
such Holder of Preferred Securities may institute, to the fullest extent
permitted by law, a legal proceeding directly against the Debenture Issuer to
enforce the Property Trustee's rights under the Indenture without first
instituting any legal proceeding against the Property Trustee or any other
Person. In addition, if a Trust Enforcement Event has occurred and is continuing
and such event is attributable to the failure of the Debenture Issuer to make
any interest, principal or other required payments when due under the Indenture,
then a Holder of Preferred Securities may institute a Direct Action against the
Debenture Issuer on or after the respective due date specified in the
Debentures.

          (d) The Property Trustee shall notify all Holders of the Preferred
Securities of any notice of any Indenture Event of Default received from the
Debenture Issuer with respect to the Debentures. Such notice shall state that
such Indenture Event of Default also constitutes a Trust Enforcement Event.
Except with respect to directing the time, method and place of conducting a
proceeding for a remedy, the Property Trustee shall be under no obligation to
take any of the actions described in clauses (i) and (ii) of Section 7.5(b),
unless the Property Trustee has obtained an opinion of independent tax counsel
to the effect that the Trust will not fail to be classified as a grantor trust
for United States federal income tax purposes as a result of such action, and
that each Holder of Preferred Securities shall be treated as owning an undivided
beneficial ownership interest in the Debentures.

            (e) If the consent of the Property Trustee, as the Holder of the
Debentures, is required under the Indenture with respect to any amendment or
modification of the Indenture, the Property Trustee shall request the direction
of the Holders of the Securities with respect to such amendment or modification
and shall vote


                                       36

<PAGE>   44



with respect to such amendment or modification as directed by a Majority in
Liquidation Amount of the Securities voting together as a single class; provided
that where a consent under the Indenture would require the consent of the
Holders of a Supermajority of the aggregate principal amount of the Debentures,
the Property Trustee may give such consent only at the direction of the Holders
of at least the same Supermajority in aggregate stated liquidation amount of the
Securities. The Property Trustee shall not take any such action in accordance
with the directions of the Holders of the Securities unless the Property Trustee
has obtained an opinion of independent tax counsel to the effect that the Trust
will not fail to be classified as a grantor trust for United States federal
income tax purposes as a result of such action, and that each Holder of
Preferred Securities will be treated as owning an undivided beneficial ownership
interest in the Debentures.

          (f) A waiver of an Indenture Event of Default with respect to the
Debentures shall constitute a waiver of the corresponding Trust Enforcement
Event.

          (g) Any required approval or direction of the Holders of the Preferred
Securities may be given at a separate meeting of the Holders of the Preferred
Securities convened for such purpose, at a meeting of all of the Holders of the
Securities or pursuant to written consent. The Regular Trustees shall cause a
notice of any meeting at which Holders of the Preferred Securities are entitled
to vote to be mailed to each Holder of record of Preferred Securities. Each such
notice shall include a statement setting forth: (i) the date of such meeting;
(ii) a description of any resolution proposed for adoption at such meeting on
which such Holders are entitled to vote; and (iii) instructions for the delivery
of proxies.

          (h) No vote or consent of the Holders of the Preferred Securities
shall be required for the Trust to redeem and cancel the Preferred Securities or
distribute the Debentures in accordance with this Declaration and the terms of
the Securities.

          (i) Notwithstanding that the Holders of the Preferred Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Preferred Securities that are owned at such time by the Debenture Issuer,
the Trustees or any entity directly or indirectly controlled by, or under direct
or indirect common control with, the Debenture Issuer or any Trustee shall not
be entitled to vote or consent and shall be treated, for purposes of such vote
or consent, as if such Preferred Securities were not outstanding.

          (j) Except as provided under Section 7.5(k), the Holders of the
Preferred Securities shall have no rights to appoint or remove the Trustees, who
may be appointed, removed or replaced solely by the Holders of the Common
Securities.

          (k) If an Indenture Event of Default has occurred and is continuing,
the Property Trustee and the Delaware Trustee may be removed and replaced by a
Majority in Liquidation Amount of the Preferred Securities.

     SECTION 7.6 Voting Rights of the Common Securities.

     (a) Except as provided in Section 6.1(b), this Section 7.6 and Section 11.1
and as otherwise required by the Business Trust Act, the Trust Indenture Act or
other applicable law, the Holders of the Common Securities shall have no voting
rights.



                                       37
<PAGE>   45



          (b) Subject to Section 7.5(k), the Holders of the Common Securities
shall be entitled to vote to appoint, remove or replace any Trustee or to
increase or decrease the number of Trustees in accordance with Article 6.

          (c) Subject to Section 2.6 and only after all Trust Enforcement Events
with respect to the Preferred Securities have been cured, waived or otherwise
eliminated and subject to the requirement of the Property Trustee obtaining a
tax opinion in certain circumstances set forth in this paragraph (c), the
Holders of the Common Securities shall have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Property
Trustee, or to direct the exercise of any trust or power conferred upon the
Property Trustee under this Declaration, including the right to direct the
Property Trustee, as the holder of the Debentures, to (i) exercise the remedies
available to it under the Indenture, (ii) consent to any amendment or
modification of the Indenture or the Debentures where such consent is required
or (iii) waive any past default and its consequences that are waivable under
Section 513 of the Indenture; provided that where a consent or action under the
Indenture would require the consent or act of the Holders of a Supermajority of
the aggregate principal amount of Debentures affected thereby, only the Holders
of at least the same Supermajority of the aggregate stated liquidation amount of
the Common Securities may direct the Property Trustee to give such consent or
take such action. Except with respect to directing the time, method and place of
conducting a proceeding for a remedy, the Property Trustee shall be under no
obligation to take any of the actions described in clauses (i) and (ii) of
Section 7.6(c) unless the Property Trustee has obtained an opinion of
independent tax counsel to the effect that the Trust will not fail to be
classified as a grantor trust for United States federal income tax purposes as a
result of such action, and each Holder will be treated as owning an undivided
beneficial ownership interest in the Debentures.

          (d) If the Property Trustee fails to enforce its rights under the
Debentures after the Holders of the Common Securities have made a written
request pursuant to Section 7.6(c), the Holders of the Common Securities may
institute, to the fullest extent permitted by law, a legal proceeding directly
against the Debenture Issuer to enforce the Property Trustee's rights under the
Debentures without first instituting any legal proceeding against the Property
Trustee or any other Person.

          (e) A waiver of an Indenture Event of Default with respect to the
Debentures shall constitute a waiver of the corresponding Trust Enforcement
Event.

          (f) Any required approval or direction of the Holders of the Common
Securities may be given at a separate meeting of the Holders of the Common
Securities convened for such purpose, at a meeting of all of the Holders of the
Securities or pursuant to written consent. The Regular Trustees shall cause a
notice of any meeting at which the Holders of the Common Securities are entitled
to vote to be mailed to the Holders of the Common Securities. Such notice shall
include a statement setting forth: (i) the date of such meeting; (ii) a
description of any resolution proposed for adoption at such meeting on which the
Holders of the Common Securities are entitled to vote; and (iii) instructions
for the delivery of proxies.

          (g) No vote or consent of the Holders of the Common Securities shall
be required for the Trust to redeem and cancel the Common Securities or to
distribute the Debentures in accordance with this Declaration and the terms of
the Securities.

     SECTION 7.7 Place of Payment.

          If any Preferred Securities are not represented by one or more Global
Securities, the Trust shall maintain in the Borough of Manhattan, New York City,
State of New York, an office or agency where the



                                       38
<PAGE>   46



Preferred Securities may be presented for payment. If the Trust fails to appoint
or maintain a different office or agency, such place of payment shall be the
Corporate Trust Office. The Regular Trustees shall give prompt written notice to
the Property Trustee and the Holders of any change in the location of such
office or agency.

     SECTION 7.8 Listing.

          The Sponsor shall use its best efforts to cause the Preferred
Securities to be listed on the New York Stock Exchange.

     SECTION 7.9 Transfer of the Securities.

          (a) The Preferred Securities initially shall be, and from time to time
may be, pledged, pursuant to the terms of the Pledge Agreement, as collateral to
secure the obligations of the holders of the Corporate PIES to purchase common
shares of Industries in accordance with the terms of the Purchase Contract
Agreement.

          (b) The Preferred Securities may be transferred, in whole or in part,
only in accordance with the terms and conditions set forth in this Declaration
and the Preferred Securities. To the fullest extent permitted by law, any
transfer or purported transfer of any Preferred Security not made in accordance
with this Declaration shall be null and void.

          (c) Subject to this Section 7.9 and Section 7.12, the Preferred
Securities shall be freely transferable.

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

          (e) Upon surrender for registration of transfer of any Preferred
Securities at an office or agency of the Trust designated for such purpose, a
Regular Trustee shall execute, and the Property Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Preferred Securities of any authorized denominations and of a like aggregate
principal amount.

          (f) At the option of the Holder, Preferred Securities may be exchanged
for other Preferred Securities of any authorized denominations and of a like
aggregate principal amount, upon surrender of the Preferred Securities to be
exchanged at such office or agency. Whenever any Preferred Securities are so
surrendered for exchange, a Regular Trustee shall execute, and the Property
Trustee shall authenticate and deliver, the Preferred Securities that the Holder
making the exchange is entitled to receive.

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


                                       39
<PAGE>   47



          (h) No service charge shall be made for any registration of transfer
or exchange of Preferred Securities, but the Trust 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 Preferred
Securities.

          (i) The Common Securities shall not be transferable except as provided
in the Indenture.

     SECTION 7.10 Mutilated, Destroyed, Lost or Stolen Certificates.

     If:

          (a) any mutilated Certificates are surrendered to the Regular
Trustees, or if the Regular Trustees receive evidence to their satisfaction of
the destruction, loss or theft of any Certificate; and

          (b) there shall be delivered to the Regular Trustees such security or
indemnity as may be required by them to keep each of the Sponsor and the Trust
harmless, then, in the absence of notice that such Certificate has been acquired
by a bona fide purchaser, any Regular Trustee shall execute and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of like denomination. In connection with the
issuance of any new Certificate under this Section 7.10, the Regular Trustees
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection therewith. Any duplicate
Certificate issued pursuant to this Section 7.10 shall constitute conclusive
evidence of an ownership interest in the relevant Securities, as if originally
issued, whether or not the lost, stolen or destroyed Certificate is found at any
time.

     SECTION 7.11 Deemed Holders.

          The Trustees may treat the Person in whose name any Securities are
registered on the register of the Trust as the sole holder of such Securities
for purposes of receiving Distributions and for all other purposes whatsoever.
Accordingly, the Trustees shall not be bound to recognize any equitable or other
claim to or interest in the Securities represented on the part of any Person,
whether or not the Trust has actual or other notice thereof.

     SECTION 7.12 Global Securities.

          (a) The Preferred Securities initially shall be issued in the form of
one or more Global Securities. A Regular Trustee shall execute, and the Property
Trustee shall authenticate and deliver, one or more Global Securities that (i)
shall represent and be denominated in an amount equal to the aggregate stated
liquidation amount of all of the Preferred Securities to be issued in the form
of Global Securities and not yet canceled, (ii) shall be registered in the name
of the Depositary for the Preferred Securities or the nominee of such Depositary
and (iii) shall be delivered by the Property Trustee to such Depositary or
pursuant to such Depositary's instructions. Global Securities shall bear a
legend substantially to the following effect:

            "This Preferred Security is a Global Security within the meaning of
            the Declaration hereinafter referred to and is registered in the
            name of The Depository Trust Company, a New York corporation (the
            "Depositary"), or a nominee of the Depositary. This Preferred
            Security is exchangeable for Preferred Securities registered in the
            name of a person other than the Depositary or its nominee only in
            the limited circumstances



                                       40
<PAGE>   48




             described in the Declaration, and no transfer of this Preferred
             Security (other than a transfer of this Preferred Security as a
             whole by the Depositary to a nominee of the Depositary or by a
             nominee of the Depositary to the Depositary or another nominee of
             the Depositary) may be registered except in limited
             circumstances.

             Unless this certificate is presented by an authorized
             representative of the Depositary to NIPSCO Capital Trust I or its
             agent for registration of transfer, exchange or payment, and any
             certificate issued is registered in the name of Cede & Co. or
             such other name as requested by an authorized representative of
             the Depositary (and any payment hereon is made to Cede & Co. or
             to such other entity as is requested by an authorized
             representative of the Depositary), and except as otherwise
             provided in the Declaration, ANY TRANSFER, PLEDGE OR OTHER USE
             HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
             since the registered owner hereof, Cede & Co., has an interest
             herein."

          (b) Preferred Securities not represented by a Global Security issued
in exchange for all or a part of a Global Security pursuant to this Section 7.12
shall be registered in such names and in such authorized denominations as the
Depositary, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Property Trustee. Upon execution and
authentication, the Property Trustee shall deliver any Preferred Securities not
represented by a Global Security to the Persons in whose names such definitive
Preferred Securities are so registered.

          (c) At such time as all interests in Global Securities have been
redeemed, repurchased or canceled, such Global Securities shall be canceled,
upon receipt thereof, by the Property Trustee in accordance with standing
procedures of the Depositary. At any time prior to such cancellation, if any
interest in a Global Security is exchanged for Preferred Securities not
represented by a Global Security, redeemed, canceled or transferred to a
transferee who receives Preferred Securities not represented by a Global
Security, or if any Preferred Security not represented by a Global Security is
exchanged or transferred for part of a Global Security, then, in accordance with
the standing procedures of the Depositary, the aggregate stated liquidation
amount of such Global Security shall be reduced or increased, as the case may
be, and an endorsement shall be made on such Global Security by the Property
Trustee to reflect such reduction or increase.

          (d) The Trust and the Property Trustee, as the authorized
representative of the Holders of the Preferred Securities, may deal with the
Depositary for all purposes of this Declaration, including the making of
payments due on the Preferred Securities and exercising the rights of Holders of
the Preferred Securities hereunder. The rights of any Beneficial Owners shall be
limited to those established by law and agreements between such owners and
Depository Participants; provided that no such agreement shall give to any
Person any rights against the Trust or the Property Trustee without the written
consent of the parties so affected. Multiple requests and directions from and
votes of the Depositary as the Holder of the Preferred Securities represented by
Global Securities with respect to any particular matter shall not be deemed
inconsistent to the extent they do not represent an amount of Preferred
Securities in excess of those held in the name of the Depositary or its nominee.

          (e) If at any time the Depositary notifies the Trust that it is
unwilling or unable to continue as Depositary for the Preferred Securities or if
at any time the Depositary no longer is eligible to serve as Depositary, the
Regular Trustees shall appoint a successor Depositary with respect to the
Preferred Securities. If a successor Depositary is not appointed by the Trust
within 90 days after the Trust receives


                                       41

<PAGE>   49



such notice or becomes aware of such ineligibility, the Trust's election that
the Preferred Securities be represented by one or more Global Securities shall
no longer be effective, and a Regular Trustee shall execute, and the Property
Trustee will authenticate and deliver, Preferred Securities in definitive
registered form, in any authorized denominations, in an aggregate stated
liquidation amount equal to the aggregate stated liquidation amount of the
Global Securities representing the Preferred Securities, in exchange for such
Global Securities.

          (f) The Regular Trustees at any time and in its sole discretion may
determine that the Preferred Securities issued in the form of one or more Global
Securities shall no longer be represented by Global Securities. In such event a
Regular Trustee on behalf of the Trust shall execute, and the Property Trustee
shall authenticate and deliver, Preferred Securities in definitive registered
form, in any authorized denominations, in an aggregate stated liquidation amount
equal to the aggregate stated liquidation amount of the Global Securities
representing the Preferred Securities, in exchange for such Global Securities.

          (g) Notwithstanding any other provisions of this Declaration (other
than the provisions set forth in Section 7.9), Global Securities may not be
transferred as a whole except by the Depositary to a nominee of the Depositary
or by a nominee of the Depositary to the Depositary or another nominee of the
Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary.

          (h) Interests of Beneficial Owners may be transferred or exchanged for
Preferred Securities not represented by a Global Security, and Preferred
Securities not represented by a Global Security may be transferred or exchanged
for a Global Security or Securities, in accordance with rules of the Depositary
and the provisions of Section 7.9.

     SECTION 7.13 Remarketing.

          (a) The Debenture Issuer shall request, not later than 15 nor more
than 30 calendar days prior to the Remarketing Date, that the Depositary notify
the Holders of the Preferred Securities and the holders of Corporate PIES of the
Remarketing and of the procedures that must be followed if a Holder of Corporate
PIES wishes to make a Cash Settlement.

          (b) Not later than 5:00 P.M., New York City time, on the seventh
Business Day preceding the Purchase Contract Settlement Date, each Holder of
Preferred Securities may elect to have the Preferred Securities held by such
Holder remarketed in the Remarketing. Under Section 5.4 of the Purchase Contract
Agreement, holders of Corporate PIES that do not give notice of their intention
to make a Cash Settlement of the Purchase Contract component of their Corporate
PIES prior to such time in the manner specified in such Section, or that give
such notice but fail to deliver cash prior to 11:00 A.M., New York City time, on
or prior to the fifth Business Day preceding the Purchase Contract Settlement
Date, shall be deemed to have consented to the disposition of the Preferred
Securities component of their Corporate PIES in the Remarketing. Holders of the
Preferred Securities that are not a component of Corporate PIES wishing to have
their Preferred Securities remarketed shall give to the Purchase Contract Agent
notice of their election prior to 11:00 A.M., New York City time on such fifth
Business Day. Any such notice shall be irrevocable and may not be conditioned
upon the level at which the Reset Rate is established in the Remarketing.
Promptly after 11:00 A.M., New York City time, on such fifth Business Day, the
Purchase Contract Agent, based on the notices received by it prior to such time
(including notices from the Purchase Contract Agent as to Purchase Contracts for
which Cash Settlement has been elected and cash received), shall notify the



                                       42

<PAGE>   50



Trust, the Sponsor and the Remarketing Agent of the number of Preferred
Securities to be tendered for purchase in the Remarketing.

          (c) If any Holder of Preferred Securities does not give a notice of
its intention to make a Cash Settlement or gives such notice but fails to
deliver cash as described in Section 7.13(b), or gives a notice of election to
have Preferred Securities that are not a component of Corporate PIES remarketed,
then the Preferred Securities of such Holder shall be deemed tendered for
purchase in the Remarketing, notwithstanding any failure by such Holder to
deliver or properly deliver such Preferred Securities to the Remarketing Agent
for purchase.

          (d) The right of each Holder to have Preferred Securities tendered for
purchase shall be limited to the extent that (i) the Remarketing Agent conducts
a remarketing pursuant to the terms of the Remarketing Agreement, (ii) the
Preferred Securities tendered have not been called for redemption, (iii) the
Remarketing Agent is able to find a purchaser or purchasers for the tendered
Preferred Securities and (iv) such purchaser or purchasers deliver the purchase
price therefor to the Remarketing Agent.

          (e) On the Remarketing Date, the Remarketing Agent shall use
commercially reasonable efforts to remarket, at a price equal to 100% of the
aggregate stated liquidation amount thereof, the Preferred Securities tendered
or deemed tendered for purchase.

          (f) If, as a result of the efforts described in 7.13(e), the
Remarketing Agent determines that it will be able to remarket all of the
Preferred Securities tendered or deemed tendered for purchase at a price of 100%
of the aggregate stated liquidation amount of such Preferred Securities prior to
4:00 P.M., New York City time, on the Remarketing Date, the Remarketing Agent
shall determine the Reset Rate, which shall be the rate per annum (rounded to
the nearest one-thousandth (0.001) of one percent per annum) that the
Remarketing Agent determines, in its sole judgment, to be the lowest rate per
annum that will enable it to remarket all of the Preferred Securities tendered
or deemed tendered for Remarketing.

          (g) If none of the Holders of the Preferred Securities or the holders
of the Corporate PIES elects to have Preferred Securities remarketed in the
Remarketing, the Reset Rate shall be the rate determined by the Remarketing
Agent, in its sole discretion, as the rate that would have been established had
a Remarketing been held on the Remarketing Date.

          (h) If, by 4:00 P.M., New York City time, on the Remarketing Date, the
Remarketing Agent is unable to remarket all of the Preferred Securities tendered
or deemed tendered for purchase, a "Failed Remarketing" shall be deemed to have
occurred and the Remarketing Agent shall so advise by telephone the Depositary,
the Property Trustee, the Debenture Trustee, the Trust and the Sponsor. In the
event of a Failed Remarketing, the Reset Rate shall equal the Two-Year Benchmark
Treasury Rate plus the Applicable Margin.

          (i) By approximately 4:30 P.M., New York City time, on the Remarketing
Date, provided that there has not been a Failed Remarketing, the Remarketing
Agent shall advise, by telephone (i) the Depositary, the Property Trustee, the
Debenture Trustee, the Trust and the Sponsor of the Reset Rate determined in the
Remarketing and the number of Preferred Securities sold in the Remarketing, (ii)
each purchaser (or the Depositary Participant thereof) of the Reset Rate and the
number of Preferred Securities such purchaser is to purchase and (iii) each
purchaser to give instructions to its Depositary Participant to pay the purchase
price on the Purchase Contract Settlement Date in same day funds against
delivery of the Preferred Securities purchased through the facilities of the
Depositary.


                                       43
<PAGE>   51



          (j)  In accordance with the Depositary's normal procedures, on the
Purchase Contract Settlement Date, the transactions described above with respect
to each Preferred Security tendered for purchase and sold in the Remarketing
shall be executed through the Depositary, and the accounts of the respective
Depositary Participants shall be debited and credited and such Preferred
Securities delivered by book-entry as necessary to effect purchases and sales of
such Preferred Securities. The Depositary shall make payment in accordance with
its normal procedures.

          (k)  If any Holder of the Preferred Securities selling Preferred
Securities in the Remarketing fails to deliver such Preferred Securities, the
Depositary Participant of such selling holder and of any other Person that was
to have purchased Preferred Securities in the Remarketing may deliver to any
such other Person a number of Preferred Securities that is less than the number
of Preferred Securities that otherwise was to be purchased by such Person. In
such event, the number of Preferred Securities to be so delivered shall be
determined by such Depositary Participant, and delivery of such lesser number of
Preferred Securities shall constitute good delivery.

          (l)  The Remarketing Agent is not obligated to purchase any Preferred
Securities that otherwise would remain unsold in the Remarketing. Neither the
Trust, any Trustee, the Sponsor nor the Remarketing Agent shall be obligated in
any case to provide funds to make payment upon tender of the Preferred
Securities for Remarketing.

          (m)  Under the Remarketing Agreement, the Sponsor, in its capacity as
Debenture Issuer, shall be liable for, and shall pay, any and all costs and
expenses incurred in connection with the Remarketing, and the Trust shall not
have any liabilities for such costs and expenses.

          (n)  The tender and settlement procedures set in this Section 7.13,
including provisions for payment by purchasers of the Preferred Securities in
the Remarketing, shall be subject to modification to the extent required by the
Depositary or if the book-entry system is no longer available for the Preferred
Securities at the time of the Remarketing, to facilitate the tendering and
remarketing of the Preferred Securities in certificated form. In addition, the
Remarketing Agent may modify the settlement procedures set forth herein in order
to facilitate the settlement process.

               ARTICLE 8: DISSOLUTION AND TERMINATION OF THE TRUST

     SECTION 8.1 Dissolution and Termination of the Trust.

          (a)  The Trust shall dissolve upon the earliest of:

               (i) the bankruptcy of the Debenture Issuer, the Sponsor or
          Industries;

               (ii) the filing of a certificate of dissolution or its equivalent
          with respect to the Sponsor; the receipt by the Trust of the consent
          of the Holders of at least a Majority in Liquidation Amount of the
          Securities to dissolve the Trust and file a certificate of
          cancellation with respect to the Trust; or the revocation of the
          Sponsor's charter and the expiration of 90 days after the date of
          revocation without a reinstatement thereof;

               (iii) the entry of a decree of judicial dissolution of the
          Sponsor or the Trust;



                                       44
<PAGE>   52


               (iv) the time when all of the Securities shall have been called
          for redemption and the amounts then due shall have been paid to the
          Holders of the Securities;

               (v) upon the direction of the Sponsor, in its sole discretion, by
          notice to the Property Trustee to distribute the Debentures to the
          Holders of the Securities in exchange for all of the Securities;
          provided that the Sponsor has provided to the Property Trustee an
          opinion of counsel that the distribution of the Debentures will not be
          taxable to the Holders of the Preferred Securities for United States
          federal income tax purposes; or

               (vi) the time when all of the Regular Trustees and the Sponsor
          have consented to dissolution of the Trust, provided such action is
          taken before the issuance of any Securities.

          (b)  As soon as is practicable after the occurrence of an event
referred to in Section 8.1(a) and upon completion of the winding up and
liquidation of the Trust, the Trustees shall terminate the Trust by executing
and filing a certificate of cancellation with the Secretary of State of the
State of Delaware.

          (c)  The provisions of Section 4.2 and Article 9 shall survive the
termination of the Trust.

     SECTION 8.2 Liquidation Distribution Upon Dissolution of the Trust.

          (a)  In the event of any voluntary or involuntary liquidation,
dissolution or winding-up of the Trust pursuant to Section 8.1(a)(i), (ii),
(iii) or (v) (each a "Liquidation"), the Holders of the Securities on the date
of the Liquidation shall be entitled to receive, out of the assets of the Trust
available for distribution to the Holders of the Securities after satisfaction
of the Trust's liabilities to creditors, if any, Debentures in an aggregate
principal amount equal to the aggregate stated liquidation amount of, with an
interest rate identical to the distribution rate of, and accrued and unpaid
interest equal to accumulated and unpaid Distributions on, such Securities in
exchange for such Securities; provided if any Preferred Securities shall then be
pledged pursuant to the Pledge Agreement, the Debentures to be distributed with
respect to such Preferred Securities will be transfered to the collateral
account maintained by the Collateral Agent.

          (b)  If, notwithstanding the other provisions of this Section 8.2,
distribution of the Debentures in the manner provided herein is determined by
the Property Trustee not to be practical, the assets of the Trust shall be
liquidated, and the Trust shall be wound-up by the Property Trustee in such
manner as the Property Trustee determines. In such event, the Holders will be
entitled to receive out of the assets of the Trust available for distribution to
the Holders, after satisfaction of liabilities to creditors of the Trust as
provided by applicable law, an amount equal to the stated liquidation amount of
$50 per Security plus accumulated and unpaid Distributions thereon to the date
of payment (such amount being the "Liquidation Distribution"). If, upon any such
Liquidation, the Liquidation Distribution can be paid only in part because the
Trust has insufficient assets available to pay the aggregate Liquidation
Distribution in full, then the amounts payable directly by the Trust on the
Securities shall be paid on a Pro Rata basis, provided that if an Indenture
Event of Default has occurred and is continuing, then the Preferred Securities
shall have a preference over the Common Securities with regard to the
Liquidation Distribution.

          (c)  Notice of any distribution of Debentures in exchange for the
Securities (an "Exchange Notice"), which notice shall be irrevocable, shall be
given by the Regular Trustees on behalf of the Trust by mail to each Holder of
Securities at least 30 but no more than 60 days before the date fixed for such
distribution. For purposes of the calculation of the date of distribution and
the dates on which notices are given pursuant to this Section 8.2(c), an
Exchange Notice shall be deemed to be given on the day such notice




                                       45

<PAGE>   53


is first mailed by first-class mail, postage prepaid, to the Holders of the
Securities. Each Exchange Notice shall be addressed to the Holders of the
Securities at the address of each such Holder appearing in the register of the
Trust. No defect in the Exchange Notice or in the mailing of either thereof with
respect to any Holder shall affect the validity of the distribution proceedings
with respect to any other Holder.

          (d)  After the date fixed for any distribution of Debentures upon
dissolution of the Trust, (i) the Securities no longer shall be deemed to be
outstanding and (ii) the Certificates shall be deemed to represent the
Debentures in a principal amount equal to the stated liquidation amount of the
Securities, bearing accrued and unpaid interest in an amount equal to the
accumulated and unpaid Distributions on the Securities, until such Certificates
are presented to the Regular Trustees or agent for transfer or reissuance.


                      ARTICLE 9: LIMITATION OF LIABILITY OF
           HOLDERS OF THE SECURITIES, THE DELAWARE TRUSTEE AND OTHERS

     SECTION 9.1 Liability.

          (a)  Except as expressly set forth in this Declaration, the Guarantee
and the terms of the Securities, the Sponsor:

               (i) shall not be personally liable for the return of any portion
          of the capital contributions (or any return thereon) of the Holders of
          the Securities that will be made solely from assets of the Trust; and

               (ii) shall not be required to pay to the Trust or to any Holder
          of the Securities any deficit, upon dissolution of the Trust or
          otherwise.

          (b)  Pursuant to Section 3803(a) of the Business Trust Act, the
Holders of the Common Securities shall be entitled to the same limitation of
personal liability extended to stockholders of private corporations for profit
organized under the General Corporation Law of the State of Delaware; provided
that the Holders of the Common Securities shall be liable for all of the debts
and obligations of the Trust (other than with respect to the Securities) to the
extent such debts and obligations are not satisfied out of the Trust's assets.

          (c)  Pursuant to Section 3803(a) of the Business Trust Act, the
Holders of the Preferred Securities shall be entitled to the same limitation of
personal liability extended to stockholders of private corporations for profit
organized under the General Corporation Law of the State of Delaware.

     SECTION 9.2 Exculpation.

          (a)  No Indemnified Person shall be liable, responsible or accountable
in damages or otherwise to the Trust or to any Covered Person for any loss,
damage or claim incurred by reason of any act or omission performed or omitted
by such Indemnified Person in good faith on behalf of the Trust and in a manner
that such Indemnified Person reasonably believed to be within the scope of the
authority conferred on such Indemnified Person by this Declaration or by law,
except that an Indemnified Person shall be liable for any such loss, damage or
claim incurred by reason of such Indemnified Person's gross negligence (or, in
the case of the Property Trustee, negligence) or willful misconduct with respect
to such acts or omissions.


                                       46
<PAGE>   54


          (b)  Each Indemnified Person shall be fully protected in relying in
good faith upon the records of the Trust and upon such information, opinions,
reports or statements presented to the Trust by any Person as to matters such
Indemnified Person reasonably believes to be within such other Person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Trust, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses or any other facts pertinent to the existence and amount of assets from
which distributions to Holders of the Securities might properly be paid.

     SECTION 9.3 Fiduciary Duty.

          (a)  To the extent that, at law or in equity, an Indemnified Person
has duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to any other Covered Person, an Indemnified Person acting under this
Declaration shall not be liable to the Trust or to any other Covered Person for
its good faith reliance on the provisions of this Declaration. The provisions of
this Declaration, to the extent that they restrict the duties and liabilities of
an Indemnified Person otherwise existing at law or in equity (other than the
duties imposed on the Property Trustee under the Trust Indenture Act), are
agreed by the parties hereto to replace such other duties and liabilities of
such Indemnified Person.

          (b)  Unless otherwise expressly provided herein:

               (i) whenever a conflict of interest exists or arises between a
          Covered Person and an Indemnified Person; or

               (ii) whenever this Declaration or any other agreement
          contemplated herein or therein provides that an Indemnified Person
          shall act in a manner that is, or provides terms that are, fair and
          reasonable to the Trust or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices and any applicable generally accepted accounting
practices or principles. In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Declaration or any other agreement
contemplated herein or of any duty or obligation of the Indemnified Person at
law or in equity or otherwise.

          (c)  Whenever in this Declaration an Indemnified Person is permitted
or required to make a decision:

               (i) in its "discretion" or under a grant of similar authority,
          the Indemnified Person shall be entitled to consider such interests
          and factors as it desires, including its own interests, and shall have
          no duty or obligation to give any consideration to any interest of or
          factors affecting the Trust or any other Person; or

               (ii) in its "good faith" or under another express standard, the
          Indemnified Person shall act under such express standard and shall not
          be subject to any other or different standard imposed by this
          Declaration or by applicable law.

     SECTION 9.4 Indemnification.


                                       47
<PAGE>   55


          (a)  (i) Pursuant to the Indenture, the Debenture Issuer shall
          indemnify, to the full extent permitted by law, any Debenture Issuer
          Indemnified Person who was or is a party or is threatened to be made a
          party to any threatened, pending or completed action, suit or
          proceeding, whether civil, criminal, administrative or investigative
          (other than an action by or in the right of the Trust), by reason of
          the fact that he or she is or was a Debenture Issuer Indemnified
          Person against expenses (including attorney fees), judgments, fines
          and amounts paid in settlement actually and reasonably incurred by him
          in connection with such action, suit or proceeding if he or she acted
          in good faith and in a manner that he or she reasonably believed to be
          in or not opposed to the best interests of the Trust and, with respect
          to any criminal action or proceeding, had no reasonable cause to
          believe his or her conduct was unlawful. The termination of any
          action, suit or proceeding by judgment, order, settlement, conviction
          or upon a plea of nolo contendere or its equivalent shall not, of
          itself, create a presumption that the Debenture Issuer Indemnified
          Person did not act in good faith and in a manner that he or she
          reasonably believed to be in or not opposed to the best interests of
          the Trust and, with respect to any criminal action or proceeding, had
          reasonable cause to believe that his conduct was unlawful.

               (ii) Pursuant to the Indenture, the Debenture Issuer shall
          indemnify, to the full extent permitted by law, any Debenture Issuer
          Indemnified Person who was or is a party or is threatened to be made a
          party to any threatened, pending or completed action or suit by or in
          the right of the Trust to procure a judgment in its favor by reason of
          the fact that he or she is or was a Debenture Issuer Indemnified
          Person against expenses (including attorneys' fees) actually and
          reasonably incurred by him or her in connection with the defense or
          settlement of such action or suit if he or she acted in good faith and
          in a manner he or she reasonably believed to be in or not opposed to
          the best interests of the Trust and except that no such
          indemnification shall be made in respect of any claim, issue or matter
          as to which such Debenture Issuer Indemnified Person was adjudged to
          be liable to the Trust, unless and only to the extent that the Court
          of Chancery of Delaware or the court in which such action or suit was
          brought determines upon application that, despite the adjudication of
          liability but in view of all the circumstances of the case, such
          person is fairly and reasonably entitled to indemnity for such
          expenses that such Court of Chancery or such other court shall deem
          proper.

               (iii) Any indemnification under paragraphs (i) and (ii) of this
          Section 9.4(a) (unless ordered by a court) shall be made by the
          Debenture Issuer only as authorized in the specific case upon a
          determination that indemnification of the Debenture Issuer Indemnified
          Person is proper in the circumstances because he or she has met the
          applicable standard of conduct set forth in paragraphs (i) and (ii).
          Such determination shall be made (A) by a majority vote of a quorum of
          the Regular Trustees who were not parties to such action, suit or
          proceeding, (B) if such a quorum is not obtainable, or, even if
          obtainable, if a quorum of disinterested Regular Trustees so directs,
          by independent legal counsel in a written opinion, or (C) by the
          Holders of the Common Securities.

               (iv) Expenses (including attorneys' fees) incurred by a Debenture
          Issuer Indemnified Person in defending a civil, criminal,
          administrative or investigative action, suit or proceeding referred to
          in paragraphs (i) and (ii) of this Section 9.4(a) shall be paid by the
          Debenture Issuer in advance of the final disposition of such action,
          suit or proceeding upon receipt of an undertaking by or on behalf of
          such Debenture Issuer Indemnified Person to repay such amount if it
          shall ultimately be determined that he or she is not entitled to be
          indemnified by the Debenture Issuer as authorized in this Section
          9.4(a). Notwithstanding the foregoing, no advance

                                       48
<PAGE>   56


          shall be made by the Debenture Issuer if a determination is reasonably
          and promptly made (A) by a majority vote of a quorum of disinterested
          Regular Trustees, (B) if such a quorum is not obtainable, or, even if
          obtainable, if a quorum of disinterested Regular Trustees so directs,
          by independent legal counsel in a written opinion or (C) the Holders
          of the Common Securities, that, based upon the facts known to the
          Regular Trustees, counsel or the Holders of the Common Securities at
          the time such determination is made, such Debenture Issuer Indemnified
          Person acted in bad faith or in a manner that such Person did not
          believe to be in or not opposed to the best interests of the Trust,
          or, with respect to any criminal proceeding, that such Debenture
          Issuer Indemnified Person believed or had reasonable cause to believe
          his or her conduct was unlawful. In no event shall any advance be made
          in instances where the Regular Trustees, independent legal counsel or
          the Holders of the Common Securities reasonably determine that such
          Person deliberately breached his or her duty to the Trust or to the
          Holders of the Securities.

               (v) The indemnification and advancement of expenses provided by,
          or granted pursuant to, the other paragraphs of this Section 9.4(a)
          shall not be deemed exclusive of any other rights to which those
          seeking indemnification and advancement of expenses may be entitled
          under any agreement, vote of stockholders or disinterested directors
          of the Debenture Issuer or the Holders of the Preferred Securities or
          otherwise, both as to action in an official capacity and as to action
          in another capacity while holding such office. All rights to
          indemnification under this Section 9.4(a) shall be deemed to be
          provided by a contract between the Debenture Issuer and each Debenture
          Issuer Indemnified Person who serves in such capacity at any time
          while this Section 9.4(a) is in effect. Any repeal or modification of
          this Section 9.4(a) shall not affect any rights or obligations then
          existing.

               (vi) The Debenture Issuer or the Trust may purchase and maintain
          insurance on behalf of any Person who is or was a Debenture Issuer
          Indemnified Person against any liability asserted against him or her
          and incurred by him or her in any such capacity, or arising out of his
          or her status as such, whether or not the Debenture Issuer would have
          the power to indemnify him or her against such liability under the
          provisions of this Section 9.4(a).

               (vii) For purposes of this Section 9.4(a), references to "the
          Trust" shall include, in addition to the resulting or surviving
          entity, any constituent entity (including any constituent of a
          constituent) absorbed in a consolidation or merger, so that any Person
          who is or was a director, trustee, officer or employee of such
          constituent entity, or is or was serving at the request of such
          constituent entity as a director, trustee, officer, employee or agent
          of another entity, shall stand in the same position under the
          provisions of this Section 9.4(a) with respect to the resulting or
          surviving entity as he or she would have had with respect to such
          constituent entity if its separate existence had continued.

               (viii) The indemnification and advancement of expenses provided
          by, or granted pursuant to, this Section 9.4(a) shall continue, unless
          otherwise provided when authorized or ratified, as to a Person who has
          ceased to be a Debenture Issuer Indemnified Person and shall inure to
          the benefit of the heirs, executors and administrators of such a
          Person. The obligation to indemnify as set forth in this Section
          9.4(a) shall survive the resignation or removal of the Delaware
          Trustee or the Property Trustee or the termination of this
          Declaration.

          (b)  Pursuant to the Indenture, the Debenture Issuer agrees to
indemnify, to the fullest extent permitted by law, the (i) Property Trustee,
(ii) the Delaware Trustee, (iii) any Affiliate of the Property

                                       49
<PAGE>   57


Trustee or the Delaware Trustee and (iv) any officers, directors, shareholders,
members, partners, employees, representatives, custodians, nominees or agents of
the Property Trustee and the Delaware Trustee (each of the Persons in (i)
through (iv) being referred to as a "Fiduciary Indemnified Person") for, and to
hold each Fiduciary Indemnified Person harmless against, any loss, liability or
expense incurred without gross negligence (or, in the case of the Property
Trustee, negligence) 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 (including reasonable legal fees and expenses)
of defending itself against or investigating any claim or liability in
connection with the exercise or performance of any of its powers or duties
hereunder. The obligation to indemnify as set forth in this Section 9.4(b) shall
survive the satisfaction and discharge of this Declaration.

     SECTION 9.5 Outside Businesses.

          Any Covered Person, the Sponsor, the Delaware Trustee and the Property
Trustee (subject to Section 6.3(c)) may engage in or possess an interest in
other business ventures of any nature or description, independently or with
others, similar or dissimilar to the activities of the Trust, and the Trust and
the Holders of the Securities shall have no rights by virtue of this Declaration
in and to such independent ventures or the income or profits derived therefrom,
and the pursuit of any such venture, even if competitive with the activities of
the Trust, shall not be deemed wrongful or improper. Each Covered Person, the
Sponsor, the Delaware Trustee and the Property Trustee shall not be obligated to
present any particular investment or other opportunity to the Trust even if such
opportunity is of a character that, if presented to the Trust, could be taken by
the Trust, and any Covered Person, the Sponsor, the Delaware Trustee and the
Property Trustee shall have the right to take for its own account (individually
or as a partner or fiduciary) or to recommend to others any such particular
investment or other opportunity. Any Covered Person, the Delaware Trustee and
the Property Trustee may engage or be interested in any financial or other
transaction with the Sponsor or any Affiliate of the Sponsor, or may act as
depositary for, trustee or agent for, or act on any committee or body of holders
of, securities or other obligations of the Sponsor or its Affiliates.


                             ARTICLE 10: ACCOUNTING

     SECTION 10.1 Fiscal Year.

          The fiscal year ("Fiscal Year") of the Trust shall be the calendar
year, or such other year as is required by the Code.

     SECTION 10.2 Certain Accounting Matters.

          (a)  At all times during the existence of the Trust, the Regular
Trustees shall keep, or shall cause to be kept, full books of account, records
and supporting documents, which shall reflect in reasonable detail each
transaction of the Trust. The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied. The Trust shall use the accrual method of
accounting for United States federal income tax purposes. The books of account
and the records of the Trust shall be examined by and reported upon as of the
end of each Fiscal Year of the Trust by a firm of independent certified public
accountants selected by the Regular Trustees.

          (b)  The Regular Trustees shall cause to be prepared and delivered to
each Holder of Securities, within 90 days after the end of each Fiscal Year of
the Trust, annual financial statements of the Trust,

                                       50
<PAGE>   58


including a balance sheet of the Trust as of the end of such Fiscal Year, and
the related statements of income or loss.

          (c)  The Regular Trustees shall cause to be duly prepared and
delivered to each Holder of Securities an annual United States federal income
tax information statement, required by the Code, containing such information
with regard to the Securities held by each Holder as is required by the Code and
the Treasury Regulations. Notwithstanding any right under the Code to deliver
any such statement at a later date, the Regular Trustees shall endeavor to
deliver all such statements within 30 days after the end of each Fiscal Year of
the Trust.

          (d)  The Regular Trustees shall cause to be duly prepared and filed
with the appropriate taxing authority an annual United States federal income tax
return, on Form 1041 or such other form required by United States federal income
tax law, and any other annual income tax returns required to be filed on behalf
of the Trust with any state or local taxing authority.

     SECTION 10.3 Banking.

          The Trust shall maintain one or more bank accounts in the name and for
the sole benefit of the Trust; provided that all payments of funds in respect of
the Debentures held by the Property Trustee shall be made directly to the
Property Account and no other funds of the Trust shall be deposited in the
Property Account. The sole signatories for such accounts shall be designated by
the Regular Trustees; provided that the Property Trustee shall designate the
signatories for the Property Account.

     SECTION 10.4 Withholding.

          The Trust and the Regular Trustees shall comply with all withholding
requirements under United States federal, state and local law. The Regular
Trustees shall request, and the Holders of the Securities shall provide to the
Trust, such forms or certificates as are necessary to establish an exemption
from withholding with respect to each Holder of Securities and any
representations and forms as shall reasonably be requested by the Regular
Trustees to assist them in determining the extent of, and in fulfilling, the
Trust's withholding obligations. The Regular Trustees shall file required forms
with applicable jurisdictions and, unless an exemption from withholding is
properly established by a Holder of Securities, shall remit amounts withheld
with respect to such Holder to applicable jurisdictions. To the extent that the
Trust is required to withhold and pay over any amounts to any authority with
respect to distributions or allocations to any Holder of Securities, the amount
withheld shall be deemed to be a distribution in the amount of the withholding
to such Holder. In the event of any claimed over withholding, a Holder shall be
limited to an action against the applicable jurisdiction. If the amount required
to be withheld was not withheld from actual Distributions made, the Trust may
reduce subsequent Distributions by the amount of such withholding.


                       ARTICLE 11: AMENDMENTS AND MEETINGS

     SECTION 11.1 Amendments.

          (a)  Except as otherwise provided in this Declaration or by any
applicable terms of the Securities, this Declaration may be amended only by a
written instrument approved and executed by (i) the Sponsor and (ii) the Regular
Trustees (or, if there are more than two Regular Trustees, a majority of the
Regular Trustees) and (iii) the Property Trustee (if the amendment affects the
rights, powers, duties, obligations or immunities

                                       51
<PAGE>   59


of the Property Trustee) and (iv) the Delaware Trustee (if the amendment affects
the rights, powers, duties, obligations or immunities of the Delaware Trustee).

          (b)  No amendment shall be made, and any such purported amendment
shall be void and ineffective:

               (i) unless, in the case of any proposed amendment, the Property
          Trustee first has received an Officers' Certificate from each of the
          Trust and the Sponsor that such amendment is permitted by, and
          conforms to, the terms of this Declaration (including the terms of the
          Securities);

               (ii) unless, in the case of any proposed amendment that affects
          the rights, powers, duties, obligations or immunities of the Property
          Trustee, the Property Trustee first has received:

                    (A) an Officers' Certificate from each of the Trust and the
               Sponsor that such amendment is permitted by, and conforms to, the
               terms of this Declaration (including the terms of the
               Securities); and

                    (B) an opinion of counsel (which may be counsel to the
               Sponsor or the Trust) that such amendment is permitted by, and
               conforms to, the terms of this Declaration (including the terms
               of the Securities); and

               (iii) to the extent the result of such amendment would be to:

                    (A) cause the Trust to be classified other than as a grantor
               trust for United States federal income tax purposes;

                    (B) reduce or otherwise adversely affect the powers of the
               Property Trustee in contravention of the Trust Indenture Act; or

                    (C) cause the Trust to be deemed to be an Investment Company
               required to be registered under the Investment Company Act.

          (c)  At such time after the Trust has issued any Securities that
remain outstanding, (i) any amendment that would (A) adversely affect the
powers, preferences or special rights of the Securities, whether by way of
amendment to this Declaration or otherwise or (B) result in the dissolution,
winding-up or termination of the Trust other than pursuant to the terms of this
Declaration shall not be effective except with the approval of the Holders of at
least a 662/3% in Liquidation Amount of the Securities; provided that if any
amendment or proposal referred to in clause (A) above would adversely affect
only the Preferred Securities or the Common Securities, then only the Holders of
the affected class will be entitled to vote on such amendment or proposal, and
such amendment or proposal shall not be effective except with the approval of a
662/3% in Liquidation Amount of the Holders of the class of Securities affected
thereby; and (ii) any amendment that would (A) change the amount or timing of
any distribution of the Securities or otherwise adversely affect the amount of
any distribution required to be made in respect of the Securities as of a
specified date or (B) restrict the right of a Holder of Securities to institute
suit for the enforcement of any such payment on or after such date shall not be
effective except with the approval of each Holder of Securities affected
thereby.

amendment does not have a material adverse effect on the rights, preferences or
privileges of the Holders of the Securities:

               (i) to cure any ambiguity;

          that may be defective or inconsistent with any other provision of this

               (v) to modify, eliminate and add to any provision of this
          Declaration to ensure that the Trust will be classified as a grantor
          trust for United States federal income tax purposes at all times that
          any Securities are outstanding or to ensure that the Trust will not be
          required to register as an Investment Company under the Investment
          Company Act; provided that such modification, elimination or addition
          would not adversely affect in any material respect the rights,

at any time by the Regular Trustees to consider and act on any matter on which
Holders of such class of Securities are entitled to act under the terms of this
Declaration, the terms of the Securities or the rules of any stock exchange on
which the Preferred Securities are listed or admitted for trading. The Regular
Trustees shall call a meeting of the Holders of such class if directed to do so
by the Holders of at least 10% in Liquidation Amount of such class of
Securities. Such direction shall be given by delivering to the Regular Trustees
a writing stating that the signing Holders of the Securities wish to call a
meeting and indicating the general or specific purpose for which the meeting is
to be called. The Holder or Holders of the Securities calling a meeting shall
specify in writing the Securities held by such Holder or Holders, and only those
Securities specified shall be counted for purposes of determining whether the
required percentage set forth in the second sentence of this paragraph has been
met.

          (b)  Except to the extent otherwise provided in the terms of the
Securities, the following provisions shall apply to meetings of the Holders of
the Securities:

               (i) Notice of any such meeting shall be given to all the Holders
          of the Securities having a right to vote thereat at least seven days
          and not more than 60 days before the date of such meeting. Whenever a
          vote, consent or approval of the Holders of the Securities is
          permitted or required under this Declaration or the rules of any stock
          exchange on which the Preferred Securities are listed or admitted for
          trading, such vote, consent or approval may be given at a meeting of
          the Holders of the Securities. Any action that may be taken at a
          meeting of the Holders of the Securities may be taken without a
          meeting and without prior notice if a consent in writing setting forth
          the action so taken is signed by the Holders of the Securities owning
          not less than the minimum amount of Securities in liquidation amount
          that would be necessary to authorize or take such action at a meeting
          at which all Holders of the Securities having a right to vote thereon
          were present and voting. Prompt notice of the taking of action without
          a meeting shall be given to the Holders of the Securities entitled to
          vote who have not consented in writing. The Regular Trustees may
          specify that any written ballot submitted to the Holders of the
          Securities for the purpose of taking any action without a meeting
          shall be returned to the Trust within the time specified by the
          Regular Trustees.

               (ii) Each Holder of the Securities may authorize any Person to
          act for it by proxy on any or all matters in which such Holder is
          entitled to participate, including waiving notice of any meeting, or
          voting or participating at a meeting. No proxy shall be valid after
          the expiration of 11 months from the date thereof unless otherwise
          provided in the proxy. Every proxy shall be revocable at the pleasure
          of the Holder of Securities executing such proxy. Except as otherwise
          provided herein, all matters relating to the giving, voting or
          validity of proxies shall be governed by the General Corporation Law
          of the State of Delaware relating to proxies, and judicial
          interpretations thereunder, as if the Trust were a Delaware
          corporation and the Holders of the Securities were stockholders of a
          Delaware corporation.

               (iii) Each meeting of the Holders of the Securities shall be
          conducted by the Regular Trustees or by such other Person that the
          Regular Trustees may designate.

               (iv) Unless the Business Trust Act, this Declaration, the terms
          of the Securities, the Trust Indenture Act or the listing rules of any
          stock exchange on which the Preferred Securities are then listed for
          trading otherwise provides, the Regular Trustees, in their sole
          discretion, shall establish all other provisions relating to meetings
          of Holders of the Securities, including notice of the time, place or
          purpose of any meeting at which any matter is to be voted on by any
          Holders of the Securities, waiver of any such notice, action by
          consent without a meeting, the establishment of a record date, quorum
          requirements, voting in person or by proxy or any other matter with
          respect to the exercise of any such right to vote.

Section 2.1       Designation and Principal Amount.

                  There is hereby authorized a series of Securities designated

                  If distributed to holders of Preferred Securities in
connection with the involuntary or voluntary dissolution of the Trust:

                  (a) The Debentures in certificated form may be presented to
the Trustee by the Property Trustee in exchange for a Global Security in an
aggregate principal amount equal to all Outstanding Debentures (a "Global
Debenture"). The Depositary for the Debentures will be The Depository Trust
Company. The Global Debentures will be registered in the name of the Depositary
or its nominee, Cede & Co., and delivered by the Trustee to the Depositary or a
custodian appointed by the Depositary for crediting to the accounts of its
participants pursuant to the instructions of the Regular Trustees. Capital

Trustee by the Property Trustee, and any Preferred Security Certificate which

depositary for the Preferred Securities or its nominee ("Non Book-Entry
Preferred Securities") will be deemed to represent beneficial interests in
Debentures presented to the Trustee by the Property Trustee having an aggregate
principal amount equal to the aggregate liquidation amount of the Non Book-Entry
Preferred Securities until such Preferred Security Certificates are presented to

the holder of the Preferred Security Certificate or the transferee of the holder
of such Preferred Security Certificate, as the case may be, with an aggregate
principal amount equal to the aggregate liquidation amount of the Preferred
Security Certificate canceled will be executed by Capital Markets and delivered
to the Trustee for authentication and delivery in accordance with the Indenture

Property Trustee to the Trustee will be deemed to have been canceled.

                  (a) Each Debenture will bear interest at the rate of 5.90% per

the Reset Rate thereafter, payable quarterly in arrears on the Interest Payment
Dates, which shall be February 19, May 19, August 19 and November 19 of each
year, commencing May 19, 1999.

                  (b) Interest not paid on the scheduled payment date will
accumulate and compound quarterly at the rate of 5.90% per annum until February
16, 2003, and at the Reset Rate thereafter.

after the Purchase Contract Settlement Date will be reset on the third Business
Day preceding the Purchase Contract Settlement Date to the Reset Rate. The Reset
Rate will be equal to the rate per annum that results from the Remarketing,
provided that if a Failed Remarketing occurs, the Reset Rate will be equal to
(i) the Two-Year Benchmark Treasury Rate plus (ii) the Applicable Margin.

                  (e) The amount of interest payable on the Debentures for any
period will be computed (i) for any full quarterly period on the basis of a
360-day year of twelve 30-day months and (ii) for any period shorter than a full
quarterly period, on the basis of a 30-day month and, for any period less than a
month, on the basis of the actual number of days elapsed per 30-day month. In

Business Day, then payment of the interest payable on such date will be made on
the next day that is a Business Day (and without interest or other payment in
respect of any such delay), except that, if such Business Day is in the next
calendar year, then such payment will be made on the preceding Business Day.

Section 2.5       Redemption.

                  (a) If a Tax Event occurs and is continuing, Capital Markets
may, at its option and upon not less than 30 nor more than 60 days' notice to
the Holders of the Debentures, redeem the Debentures in whole (but not in part)
within 90 days following the occurrence of such Tax Event, at a price equal to,
for each Debenture, the Redemption Price. The Redemption Amount shall be paid
prior to 12:00 noon, New York City time, on the date of redemption (the "Tax
Event Redemption Date") or such earlier time as Capital Markets determines,
provided that Capital Markets shall have deposited with the Trustee an amount
sufficient to pay the Redemption Amount by 10:00 a.m. on the Tax Event
Redemption Date. Such redemption shall otherwise be in accordance with the
provisions of Article Eleven of the Indenture.

                  (b)      Except as provided in Section 2.5(a), Capital Markets
will have no right to redeem the Debentures.

                  (c)      The Debentures will not be subject to a sinking fund
provision.

                         5.90% SENIOR DEBENTURE DUE 2005

                  NIPSCO Capital Markets, Inc., an Indiana corporation ("Capital
Markets", which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to The
Chase Manhattan Bank, as Property trustee under the Declaration or registered
assigns, the principal sum of $355,700,000 Dollars on February 19, 2005, and to
pay interest on said principal sum from February 16, 1999, or from the most
recent interest payment date (each such date, an "Interest Payment Date") to
which interest has been paid or duly provided for, quarterly in arrears on
February 19, May 19, August 19 and November 19 of each year, commencing May 19,
1999, at the rate of 5.90% per annum until February 19, 2003, and at the Reset
Rate thereafter, 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 for any period will be computed (1)
for any full quarterly period on the basis of a 360-day year of twelve 30-day
months and (2) for any period shorter than a full quarterly period, on the basis
of a 30-day month and, for any period less than a month, 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 is not a Business Day, then payment of the interest
payable on such date will be made on the next 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 calendar year, then such payment will be made
on the preceding Business Day. The interest installment so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in the Indenture referred to on the reverse side hereof, be paid to 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, if this Debenture is a Global
Security, shall be the close of business on the Business Day preceding such
Interest Payment Date or, if this Debenture is not a Global Security, shall be
the close of business on the 15th Business Day preceding such Interest Payment
Date; provided that interest paid at maturity shall be paid to the Person to
whom 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 referred to on the
reverse side hereof for the payment of such defaulted interest, notice whereof
shall be given to the registered Holders of the Debentures 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 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 Capital Markets by check mailed to the registered Holder at such
address as shall appear in the Security Register. Notwithstanding the foregoing,
so long as the Holder of this Debenture is the Property Trustee, the payment of
the principal of (and premium, if any) and interest on this Debenture will be
made at such place and to such account as may be designated by the Property
Trustee.

                  This Debenture is, to the extent provided in the Indenture,
senior and unsecured and will rank in right of payment on a parity with all
other senior unsecured obligations of Capital Markets.

executed by the Trustee, 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

                  This Debenture is one of a duly authorized series of
Securities of Capital Markets (herein sometimes referred to as the
"Debentures"), all issued under and pursuant to an Indenture dated as of
February 14, 1997, duly executed and delivered among NIPSCO Industries, Inc.
("Industries"), NIPSCO Capital Markets, Inc. ("Capital Markets") and The Chase
Manhattan Bank, as Trustee (the "Trustee"), as supplemented by the First
Supplemental Indenture thereto dated as of February 16, 1999, among Industries,
Capital Markets and the Trustee (such Indenture as so supplemented, the
"Indenture"), 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, Capital Markets,
Industries and the Holders of the Debentures. By the terms of the Indenture, the
Securities 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 Securities is limited in aggregate principal amount to $355,700,000.

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

                  If a Tax Event occurs and is continuing, Capital Markets may,
at its option and upon not less than 30 nor more than 60 days' notice to the
Holders of the Debentures, redeem the Debentures in whole (but not in part)
within 90 days following the occurrence of such Tax Event at the Redemption
Price. The Redemption Price shall be paid prior to 12:00 noon, New York City
time, on the Tax Event Redemption Date, by check or wire transfer in immediately
available funds at such place and to such account as may be designated by each
such Holder.

                  The Debentures will not be subject to a sinking fund
provision.

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

                  The Indenture contains provisions permitting Capital Markets
and the Trustee, without the consent of any Holder, to execute supplemental
indentures modifying certain provisions of the Indenture and, with the consent
of the Holders of not less than a majority in aggregate principal amount of the
Debentures and all other series of Securities 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 may, without the consent of the Holder of each
outstanding Debenture, among other things, (i) change the stated maturity of the
principal of, or any installment of interest on, any Debenture, (ii) reduce the
principal amount of, or the rate of interest on or any premium payable upon the
redemption of, the Debentures, (iii) impair the right to institute suit for the
enforcement of any such payment on or after the stated maturity of or any
redemption date for the Debentures or (iv) reduce the above-stated percentage of
principal amount of Debentures, the Holders of which are required to modify or
amend the Indenture, to consent to any waiver thereunder or to approve any
supplemental indenture. The Indenture also contains provisions permitting the

                                       11

<PAGE>   12



Holders of a majority in aggregate principal amount of the Debentures at the
time Outstanding affected thereby, on behalf of all of the Holders of the
Debentures, 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 the Debentures, and its consequences, except a default in the payment
of the principal of or interest on any of the Debentures (unless cured as
provided in the Indenture) or in respect of a covenant or provision that cannot
be modified or amended without the consent of the Holders of each Debenture then
Outstanding. 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 Capital
Markets, 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.

                  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 Capital Markets, upon surrender of
this Debenture for registration of transfer at the office or agency of Capital
Markets in the City and State of New York accompanied by a written instrument or
instruments of transfer in form satisfactory to Capital Markets or the Trustee
duly executed by the registered Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Debentures of authorized denominations
and for the same aggregate principal amount will be issued to the designated
transferee or transferees. No service charge will be made for any such transfer,
but Capital Markets 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, Capital Markets, 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 Capital Markets 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
incorporator, stockholder, officer or director, past, present or future, as
such, of Capital Markets or of any predecessor or successor corporation, whether
by virtue of any constitution, statute or rule of law, or by the enforcement of
any assessment or penalty or otherwise, all such liability being, by the
acceptance hereof and as part of the consideration for the issuance hereof,
expressly waived and released.

                  The Indenture imposes certain limitations on the ability of
Capital Markets and Industries to, among other things, merge, consolidate or
sell, assign, transfer or lease all or substantially all of its properties or
assets. Such covenants and limitations are subject to a number of important
qualifications and exceptions. Capital Markets and Industries must report
periodically to the Trustee on compliance with the covenants in the Indenture.

                  The Debentures of this series are issuable only in registered
form without coupons in denominations of $50 and any integral multiple thereof.
As provided in the Indenture and subject to certain limitations herein and
therein set forth, Debentures of this series so issued are exchangeable for a
like aggregate principal amount of Debentures of this series of a different
authorized denomination, as requested by the Holder surrendering the same.

<PAGE>   15



                  If an Event of Default occurs and written notice of such event
has been given to Capital Markets, then neither Capital Markets nor Industries
may:

                  (a)      declare or pay any dividends or distributions on, or

the Common Securities;

                  (b)      cause the Trust to remain a statutory business trust
and not to voluntarily dissolve, wind up, liquidate or be terminated, except as
permitted by the Declaration;

                  (c)      use its commercially reasonable efforts to ensure
that the Trust will not be an "investment company" required to be registered
under the Investment Company Act of 1940;

                  (d) not take any action that would be reasonably likely to
cause the Trust to be classified as an association or a publicly traded
partnership taxable as a corporation for United States federal income tax
purposes; and

                  (e) pay all of the debts and obligations of the Trust (other
than with respect to the securities issued by the Trust) and all costs and
expenses of the Trust (including, but not limited to, all costs and expenses

and all costs and expenses relating to the operation of the Trust) and any and
all taxes, duties, assessments or governmental charges of whatever nature (other
than withholding taxes) imposed on the Trust by the United States, or any other
taxing authority, so that the net amounts received and retained by the Trust
after paying such expenses will be equal to the amounts the Trust would have
received had no such costs or expenses been incurred by or imposed on the Trust.
The obligations of Capital Markets in Section 5.3(e) are for the benefit of, and
shall be enforceable by, any Person to whom any such debts, obligations, costs,
expenses and taxes are owed whether or not such Person has received notice
thereof. Any such Person may enforce such obligations of

                                       15

<PAGE>   16



Capital Markets directly against Capital Markets, and Capital Markets
irrevocably waives any right or remedy to require that any such Person take any
action against the Trust or any other Person before proceeding against Capital
Markets.

Section 5.4       Additional Covenant Relating to the Guarantee.

                  If an event of default under the Guarantee occurs and written
notice of such event has been given to Capital Markets, then Capital Markets and
Industries will be subject to the limitations and restrictions set forth in
Section 5.2 relating to an Event of Default.


                                   ARTICLE VI
                          ORIGINAL ISSUE OF DEBENTURES

Section 6.1       Original Issue of Debentures.

                  Debentures in an aggregate principal amount of up to
$355,700,000 may, upon execution of this First Supplemental Indenture, be
executed by Capital Markets and delivered to the Trustee for authentication, and
the Trustee shall thereupon authenticate and deliver said Debentures upon
receipt of a Company Order, without any further action by Industries or Capital
Markets.


                                   ARTICLE VII
                    RIGHTS OF HOLDERS OF PREFERRED SECURITIES

Section 7.1       Preferred Security Holders' Rights.

                  Notwithstanding Section 507 of the Indenture, if the Property
Trustee fails to enforce its rights under the Debentures after a holder of
Preferred Securities has made a written request, the holder of Preferred
Securities may, to the fullest extent permitted by law, institute a legal
proceeding directly against Capital Markets to enforce the Property Trustee's
rights under the Indenture without first instituting any legal proceeding
against the Property Trustee or any other person or entity.

Section 7.2       Direct Action.

                  Notwithstanding any other provision of the Indenture, for as
long as any Preferred Securities remain outstanding, to the fullest extent
permitted by law, if an Event of Default has occurred and is continuing and such
event is attributable to the failure of Capital Markets to pay interest or
principal on the Debentures on the date such interest or principal is otherwise
payable (or in the case of redemption, the redemption date), then a holder of
Preferred Securities may institute a proceeding directly against Capital Markets
(a "Direct Action") to enforce payment to such holder of the principal or
interest on Debentures having an aggregate principal amount equal to the
aggregate liquidation amount of the Preferred Securities of such holder.

Section 7.3       Payments Pursuant to Direct Actions.


                                       16

<PAGE>   17



                  Capital Markets will have the right to set off against its
obligations to the Trust, as Holder of the Debentures, any payment made to a
holder of Preferred Securities in connection with a Direct Action.


                                  ARTICLE VIII
                                   REMARKETING

Section 8.1       Effectiveness of this Article.

                  This Article VIII will become effective only upon a
distribution of the Debentures upon dissolution of the Trust which occurs prior
to the Remarketing of the Preferred Securities pursuant to the Declaration.
Until such a distribution, or if such distribution occurs after the Remarketing
of the Preferred Securities pursuant to the Declaration, this Article VIII will
have no effect.

Section 8.2       Remarketing.

                  (a) Capital Markets shall request, not later than 15 nor more
than 30 calendar days prior to the Remarketing Date, that the Depositary notify
the Holders of the Debentures and the holders of the Corporate PIES of the
Remarketing and of the procedures that must be followed if a holder of Corporate
PIES wishes to make a Cash Settlement.

                  (b) Not later than 5:00 p.m., New York City time, on the
seventh Business Day preceding the Purchase Contract Settlement Date, each
Holder of Debentures may elect to have the Debentures held by such Holder
remarketed in the Remarketing. Under Section 5.4 of the Purchase Contract
Agreement, holders of Corporate PIES that do not give notice of their intention
to make a Cash Settlement of the Purchase Contract component of their Corporate
PIES prior to such time in the manner specified in such Section, or that give
such notice but fail to deliver cash prior to 11:00 a.m., New York City time, on
or prior to the fifth Business Day preceding the Purchase Contract Settlement
Date, shall be deemed to have consented to the disposition of the Debenture
component of their Corporate PIES in the Remarketing. Holders of Debentures that
are not a component of Corporate PIES wishing to have their Debentures
remarketed shall give to the Purchase Contract Agent notice of their election
prior to 11:00 a.m., New York City time, on such fifth Business Day. Any such
notice shall be irrevocable and may not be conditioned upon the level at which
the Reset Rate is established in the Remarketing. Promptly after 11:00 a.m., New
York City time, on such fifth Business Day, the Purchase Contract Agent, based
on the notices received by it prior to such time (including notices from the
Purchase Contract Agent as to Purchase Contracts for which Cash Settlement has
been elected and cash received), shall notify Capital Markets and the
Remarketing Agent of the amount of Debentures to be tendered for purchase in the
Remarketing.

                  (c) If any Holder of Debentures does not give a notice of its
intention to make a Cash Settlement or gives such notice but fails to deliver
cash as described in the foregoing subsection (b), or gives a notice of election
to have Debentures that are not a component of Corporate PIES remarketed, then
the Debentures of such Holder shall be deemed tendered for purchase in the
Remarketing, notwithstanding any failure by such Holder to deliver or properly
deliver such Debentures to the Remarketing Agent for purchase.

                  (d) The right of each Holder to have Debentures tendered for
purchase will be limited to the extent that (i) the Remarketing Agent conducts a
remarketing pursuant to the terms of the Remarketing Agreement, (ii) the
Debentures tendered have not been called for redemption, (iii) the Remarketing
Agent is able to find a purchaser or purchasers for the tendered Debentures and
(iv) such purchaser or purchasers deliver the purchase price therefor to the
Remarketing Agent.


                                       17

<PAGE>   18




                  (e) On the Remarketing Date, the Remarketing Agent will use
commercially reasonable efforts to remarket, at a price equal to 100% of the
aggregate principal amount thereof, the Debentures tendered or deemed tendered
for purchase.

                  (f) If, as a result of the efforts described in the foregoing
subsection (e), the Remarketing Agent determines that it will be able to
remarket all of the Debentures tendered or deemed tendered for purchase at a
price of 100% of their aggregate principal amount prior to 4:00 p.m., New York
City time, on the Remarketing Date, the Remarketing Agent shall determine the
Reset Rate, which shall be the rate per annum (rounded to the nearest
one-thousandth (0.001) of one percent per annum) that the Remarketing Agent
determines, in its sole judgment, to be the lowest rate per annum that will
enable it to remarket all of the Debentures tendered or deemed tendered for
Remarketing.

                  (g) If none of the Holders of the Debentures or the holders of
the Corporate PIES elects to have Debentures remarketed in the Remarketing, the
Reset Rate shall be the rate determined by the Remarketing Agent, in its sole
discretion, as the rate that would have been established had a Remarketing been
held on the Remarketing Date.

                  (h) If, by 4:00 p.m., New York City time, on the Remarketing
Date, the Remarketing Agent is unable to remarket all of the Debentures tendered
or deemed tendered for purchase, a "Failed Remarketing" shall be deemed to have
occurred, and the Remarketing Agent shall so advise by telephone the Depositary,
the Debenture Trustee and Capital Markets. In the event of a Failed Remarketing,
the Reset Rate shall equal the Two-Year Benchmark Treasury Rate plus the
Applicable Margin.

                  (i) By approximately 4:30 p.m., New York City time, on the
Remarketing Date, provided that there has not been a Failed Remarketing, the
Remarketing Agent shall advise, by telephone (i) the Depositary, the Debenture
Trustee and Capital Markets of the Reset Rate determined in the Remarketing and
the amount of Debentures sold in the Remarketing, (ii) each purchaser (or the
Depositary participant thereof) of the Reset Rate and the amount of Debentures
such purchaser is to purchase and (iii) each purchaser to give instructions to
its Depositary participant to pay the purchase price on the Purchase Contract
Settlement Date in same day funds against delivery of the Debentures purchased
through the facilities of the Depositary.

                  (j) In accordance with the Depositary's normal procedures, on
the Purchase Contract Settlement Date, the transactions described above with
respect to each Debenture tendered for purchase and sold in the Remarketing
shall be executed through the Depositary, and the accounts of the respective
Depositary participants shall be debited and credited and such Debentures
delivered by book-entry as necessary to effect purchases and sales of such
Debentures. The Depositary shall make payment in accordance with its normal
procedures.

                  (k) If any Holder of Debentures selling Debentures in the
Remarketing fails to deliver such Debentures, the Depositary participant of such
selling holder and of any other Person that was to have purchased Debentures in
the Remarketing may deliver to any such other Person an amount of Debentures
that is less than the amount of Debentures that otherwise was to be purchased by
such Person. In such event, the amount of Debentures to be so delivered shall be
determined by such Depositary participant, and delivery of such lesser amount of
Debentures shall constitute good delivery.

                                       18

<PAGE>   19



                  (l) The Remarketing Agent is not obligated to purchase any
Debentures that otherwise would remain unsold in the Remarketing. Neither
Capital Markets nor the Remarketing Agent shall be obligated in any case to
provide funds to make payment upon tender of the Debentures for Remarketing.

                  (m) Under the Remarketing Agreement, Capital Markets, in its
capacity as issuer of the Debentures, shall be liable for, and shall pay, any
and all costs and expenses incurred in connection with the Remarketing.

                  (n) The tender and settlement procedures set in this Section
8.2, including provisions for payment by purchasers of the Debentures in the
Remarketing, shall be subject to modification to the extent required by the
Depositary or if the book-entry system is no longer available for the Debentures
at the time of the Remarketing, to facilitate the tendering and remarketing of
the Debentures in certificated form. In addition, the Remarketing Agent may
modify the settlement procedures set forth herein in order to facilitate the
settlement process.

take the relevant action with respect to the Corporate PIES or the Treasury
PIES, as the case may be, whether or not such Holders remain Holders after such
record date; provided that no such action shall be effective hereunder unless
taken on or prior to the applicable Expiration Date by Holders of the requisite
number of Outstanding Securities on such record date. Nothing in this paragraph
shall be construed to prevent the Company from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be cancelled and be of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite number of Outstanding Securities on the date such action is
taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the

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

Section 1.6.  Notice to Holders; Waiver.

     Where this Agreement provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at its address as it appears in the applicable Register, not
later than the latest date, and not earlier than the earliest date, prescribed
for the giving of such notice. In any case where notice to Holders is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders. Where this Agreement provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the
Agent, but such filing shall not be a condition precedent to the validity of any
action taken in reliance upon such waiver.

     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 Agent shall constitute a
sufficient notification for every purpose hereunder.

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

Section 1.8.  Successors and Assigns.

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

Section 1.9.  Separability Clause.

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

Section 1.10.  Benefits of Agreement.

     Nothing in this Agreement or in the Securities, express or implied, shall
give to any Person, other than the parties hereto and their successors hereunder
and, to the extent provided hereby, the Holders, any benefits or any legal or
equitable right, remedy or claim under this Agreement. The Holders from time to
time shall be beneficiaries of this Agreement and shall be bound by all of the
terms and conditions hereof and of the Securities evidenced by their
Certificates by their acceptance of delivery of such Certificates.

          The Certificates shall be issuable only in registered form and only in
denominations of a single Corporate PIES or Treasury PIES and any integral
multiple thereof.

Section 3.2.   Rights and Obligations Evidenced by the Certificates.

          Each Corporate PIES Certificate shall evidence the number of Corporate
PIES specified therein, with each such Corporate PIES representing the ownership
by the Holder thereof of a beneficial interest in a Preferred Security, a
Debenture or the Applicable Ownership Interest of the Treasury Portfolio, as the
case may be, subject to the Pledge of such Preferred Security, such Debenture or
the Applicable Ownership Interest (as specified in clause (A) of the definition
of such term) of the Treasury Portfolio, as the case may be, by such Holder
pursuant to the Pledge Agreement, and the rights and obligations of the Holder
thereof and the Company under one Purchase Contract. The Agent as
attorney-in-fact for, and on behalf of, the Holder of each Corporate PIES shall
pledge, pursuant to the Pledge Agreement, the Preferred Security, the Debenture
or the Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, as the case may be, forming

Holder in such Preferred Security, such Debenture or the Applicable Ownership
Interest (as specified in clause (A) of the definition of such term) of the
Treasury Portfolio, as the case may be, for the benefit of the Company, to

Common Stock of the Company. Prior to the purchase of


                                      -18-


<PAGE>   24



shares of Common Stock under each Purchase Contract, such Purchase Contracts
shall not entitle the Holder of a Corporate PIES Certificate to any of the
rights of a holder of shares of Common Stock, including, without limitation, the
right to vote or receive any dividends or other payments or to consent or to
receive notice as a stockholder in respect of the meetings of stockholders or
for the election of directors of the Company or for any other matter, or any
other rights whatsoever as a stockholder of the Company.

          Each Treasury PIES Certificate shall evidence the number of Treasury
PIES specified therein, with each such Treasury PIES representing the ownership
by the Holder thereof of a 1/20 undivided beneficial interest in a Treasury
Security with a principal amount equal to $1,000, subject to the Pledge of such
Treasury Security by such Holder pursuant to the Pledge Agreement, and the
rights and obligations of the Holder thereof and the Company under one Purchase
Contract. Prior to the purchase, if any, of shares of Common Stock under each
Purchase Contract, such Purchase Contract shall not entitle the Holder of a
Treasury PIES Certificate to any of the rights of a holder of shares of Common
Stock, including, without limitation, the right to vote or receive any dividends
or other payments or to consent or to receive notice as a stockholder in respect
of the meetings of stockholders or for the election of directors of the Company
or for any other matter, or any other rights whatsoever as a stockholder of the
Company.

Section 3.3.   Execution, Authentication, Delivery and Dating.

          Subject to the provisions of Sections 3.13 and 3.14 hereof, upon the
execution and delivery of this Agreement, and at any time and from time to time
thereafter, the Company may deliver Certificates executed by the Company to the
Agent for authentication, execution on behalf of the Holders and delivery,
together with its Issuer Order for authentication of such Certificates, and the
Agent in accordance with such Issuer Order shall authenticate, execute on behalf
of the Holders and deliver such Certificates.

          The Certificates shall be executed on behalf of the Company by its
Chairman of the Board, its President or one of its Vice Presidents. The
signature of any of these officers on the Certificates may be manual or
facsimile.

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

          No Purchase Contract evidenced by a Certificate shall be valid until
such Certificate has been executed on behalf of the Holder by the manual
signature of an authorized signatory of the Agent, as such Holder's
attorney-in-fact. Such signature by an authorized signatory of the Agent shall
be conclusive evidence that the Holder of such Certificate has entered into the
Purchase Contracts evidenced by such Certificate.

          Each Certificate shall be dated the date of its authentication.



                                      -19-


<PAGE>   25


          No Certificate shall be entitled to any benefit under this Agreement
or be valid or obligatory for any purpose unless there appears on such
Certificate a certificate of authentication substantially in the form provided
for herein executed by an authorized signatory of the Agent by manual signature,
and such certificate upon any Certificate shall be conclusive evidence, and the
only evidence, that such Certificate has been duly authenticated and delivered
hereunder.

Section 3.4.   Temporary Certificates.

          Pending the preparation of definitive Certificates, the Company shall
execute and deliver to the Agent, and the Agent shall authenticate, execute on
behalf of the Holders, and deliver, in lieu of such definitive Certificates,
temporary Certificates which are in substantially the form set forth in Exhibit
A or Exhibit B hereto, as the case may be, with such letters, numbers or other
marks of identification or designation and such legends or endorsements printed,
lithographed or engraved thereon as may be required by the rules of any
securities exchange on which the Corporate PIES or Treasury PIES are listed, or
as may, consistently herewith, be determined by the officers of the Company
executing such Certificates, as evidenced by their execution of the
Certificates.

          If temporary Certificates are issued, the Company will cause
definitive Certificates to be prepared without unreasonable delay. After the
preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the Corporate Trust Office, at the expense of the Company and
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Certificates, the Company shall execute and deliver to the Agent, and
the Agent shall authenticate, execute on behalf of the Holder, and deliver in
exchange therefor, one or more definitive Certificates of like tenor and
denominations and evidencing a like number of Corporate PIES or Treasury PIES,
as the case may be, as the temporary Certificate or Certificates so surrendered.
Until so exchanged, the temporary Certificates shall in all respects evidence
the same benefits and the same obligations with respect to the Corporate PIES or
Treasury PIES, as the case may be, evidenced thereby as definitive Certificates.

Section 3.5.   Registration; Registration of Transfer and Exchange.

          The Agent shall keep at the Corporate Trust Office a register (the
"Corporate PIES Register") in which, subject to such reasonable regulations as
it may prescribe, the Agent shall provide for the registration of Corporate PIES
Certificates and of transfers of Corporate PIES Certificates (the Agent, in such
capacity, the "Corporate PIES Registrar") and a register (the "Treasury PIES
Register") in which, subject to such reasonable regulations as it may prescribe,
the Agent shall provide for the registration of the Treasury PIES Certificates
and transfers of Treasury PIES Certificates (the Agent, in such capacity, the
"Treasury PIES Registrar").

          Upon surrender for registration of transfer of any Certificate at the
Corporate Trust Office, the Company shall execute and deliver to the Agent, and
the Agent shall authenticate, execute on behalf of the designated transferee or
transferees, and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of any authorized


                                      -20-


<PAGE>   26



denominations, like tenor, and evidencing a like number of Corporate PIES or
Treasury PIES, as the case may be.

          At the option of the Holder, Certificates may be exchanged for other
Certificates, of any authorized denominations and evidencing a like number of
Corporate PIES or Treasury PIES, as the case may be, upon surrender of the
Certificates to be exchanged at the Corporate Trust Office. Whenever any
Certificates are so surrendered for exchange, the Company shall execute and
deliver to the Agent, and the Agent shall authenticate, execute on behalf of the
Holder, and deliver the Certificates which the Holder making the exchange is
entitled to receive.

          All Certificates issued upon any registration of transfer or exchange
of a Certificate shall evidence the ownership of the same number of Corporate
PIES or Treasury PIES, as the case may be, and be entitled to the same benefits
and subject to the same obligations, under this Agreement as the Corporate PIES
or Treasury PIES, as the case may be, evidenced by the Certificate surrendered
upon such registration of transfer or exchange.

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

          No service charge shall be made for any registration of transfer or
exchange of a Certificate, but the Company and the Agent may require payment
from the Holder 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 Certificates, other than any exchanges pursuant to Sections 3.6 and
8.5 not involving any transfer.

          Notwithstanding the foregoing, the Company shall not be obligated to
execute and deliver to the Agent, and the Agent shall not be obligated to
authenticate, execute on behalf of the Holder and deliver any Certificate in
exchange for any other Certificate presented or surrendered for registration of
transfer or for exchange on or after the Business Day immediately preceding the
earlier of the Purchase Contract Settlement Date or the Termination Date. In
lieu of delivery of a new Certificate, upon satisfaction of the applicable
conditions specified above in this Section and receipt of appropriate
registration or transfer instructions from such Holder, the Agent shall (i) if
the Purchase Contract Settlement Date has occurred, deliver the shares of Common
Stock issuable in respect of the Purchase Contracts forming a part of the
Securities evidenced by such other Certificate or (ii) if a Termination Event
shall have occurred prior to the Purchase Contract Settlement Date, transfer the
Preferred Securities, the Debentures, the Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio or the Treasury Securities, as the case may be, evidenced thereby, in
each case subject to the applicable conditions and in accordance with the
applicable provisions of Article Five hereof.

Section 3.6.   Book-Entry Interests.

          The Certificates, on original issuance, will be issued in the form of
one or more fully registered Global Certificates, to be delivered to the
Depositary by, or on behalf of, the Company.

                                      -21-


<PAGE>   27



Such Global Certificate shall initially be registered on the books and records
of the Company in the name of Cede & Co., the nominee of the Depositary, and no
Beneficial Owner will receive a definitive Certificate representing such
Beneficial Owner's interest in such Global Certificate, except as provided in
Section 3.9. The Agent shall enter into an agreement with the Depositary if so
requested by the Company. Unless and until definitive, fully registered
Certificates have been issued to Beneficial Owners pursuant to Section 3.9:

          (a)  the provisions of this Section 3.6 shall be in full force and
effect;

          (b)  the Company shall be entitled to deal with the Clearing Agency
for all purposes of this Agreement (including the payment of Contract Adjustment
Payments, if any, and receiving approvals, votes or consents hereunder) as the
Holder of the Securities and the sole holder of the Global Certificate(s) and
shall have no obligation to the Beneficial Owners;

          (c)  to the extent that the provisions of this Section 3.6 conflict
with any other provisions of this Agreement, the provisions of this Section 3.6
shall control; and

          (d)  the rights of the Beneficial Owners shall be exercised only
through the Clearing Agency and shall be limited to those established by law and
agreements between such Beneficial Owners and the Clearing Agency and/or the
Clearing Agency Participants.

Section 3.7.   Notices to Holders.

          Whenever a notice or other communication to the Holders is required to
be given under this Agreement, the Company or the Company's agent shall give
such notices and communications to the Holders and, with respect to any
Securities registered in the name of a Clearing Agency or the nominee of a
Clearing Agency, the Company or the Company's agent shall, except as set forth
herein, have no obligations to the Beneficial Owners.

Section 3.8.   Appointment of Successor Clearing Agency.

          If any Clearing Agency elects to discontinue its services as
securities depositary with respect to the Securities, the Company may, in its
sole discretion, appoint a successor Clearing Agency with respect to the
Securities.

Section 3.9.   Definitive Certificates.

          If (i) a Clearing Agency elects to discontinue its services as
securities depositary with respect to the Securities and a successor Clearing
Agency is not appointed within 90 days after such discontinuance pursuant to
Section 3.8 or (ii) there shall have occurred and be continuing a default by the
Company in respect of its obligations under one or more Purchase Contracts, then
upon surrender of the Global Certificates representing the Securities by the
Clearing Agency, accompanied by registration instructions, the Company shall
cause definitive Certificates to be delivered to Beneficial Owners in accordance
with the instructions of the Clearing Agency. The Company shall not be liable
for any delay in delivery of such instructions and may conclusively rely on and
shall be protected in relying on, such instructions.

Section 3.10.  Mutilated, Destroyed, Lost and Stolen Certificates.

          If any mutilated Certificate is surrendered to the Agent, the Company
shall execute and deliver to the Agent, and the Agent shall authenticate,
execute on behalf of the Holder, and deliver in exchange therefor, a new
Certificate, evidencing the same number of Corporate PIES or Treasury PIES, as
the case may be, and bearing a Certificate number not contemporaneously
outstanding.

          If there shall be delivered to the Company and the Agent (i) evidence
to their satisfaction of the destruction, loss or theft of any Certificate, and
(ii) such security or indemnity as may be required by them to hold each of them
and any agent of any of them harmless, then, in the absence of notice to the
Company or the Agent that such Certificate has been acquired by a bona fide
purchaser, the Company shall execute and deliver to the Agent, and the Agent
shall authenticate, execute on behalf of the Holder, and deliver to the Holder,
in lieu of any such destroyed, lost or stolen Certificate, a new Certificate,
evidencing the same number of Corporate PIES or Treasury PIES, as the case may
be, and bearing a Certificate number not contemporaneously outstanding.

          Notwithstanding the foregoing, the Company shall not be obligated to
execute and deliver to the Agent, and the Agent shall not be obligated to
authenticate, execute on behalf of the Holder, and deliver to the Holder, a
Certificate on or after the Business Day immediately preceding the earlier of
the Purchase Contract Settlement Date or the Termination Date. In lieu of
delivery of a new Certificate, upon satisfaction of the applicable conditions
specified above in this Section and receipt of appropriate registration or
transfer instructions from such Holder, the Agent shall (i) if the Purchase
Contract Settlement Date has occurred, deliver the shares of Common Stock
issuable in respect of the Purchase Contracts forming a part of the Securities
evidenced by such Certificate, or (ii) if a Termination Event shall have
occurred prior to the Purchase Contract Settlement Date, transfer the Preferred
Securities, the Debentures, the appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio or the Treasury Securities, as the case may be, evidenced thereby, in
each case subject to the applicable conditions and in accordance with the
applicable provisions of Article Five hereof.

          Upon the issuance of any new Certificate under this Section, the
Company and the Agent may require the payment by the Holder 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 Agent)
connected therewith.

          Every new Certificate issued pursuant to this Section in lieu of any
destroyed, lost or stolen Certificate shall constitute an original additional
contractual obligation of the Company and of the Holder in respect of the
Security evidenced thereby, whether or not the destroyed, lost or stolen
Certificate (and the Securities evidenced thereby) shall be at any time
enforceable by anyone, and shall be entitled to all the benefits and be subject
to all the obligations of this Agreement equally and proportionately with any
and all other Certificates delivered hereunder.

<PAGE>   29



          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 Certificates.

Section 3.11.  Persons Deemed Owners.

          Prior to due presentment of a Certificate for registration of
transfer, the Company and the Agent, and any agent of the Company or the Agent,
may treat the Person in whose name such Certificate is registered as the owner
of the Corporate PIES or Treasury PIES evidenced thereby, for the purpose of
receiving distributions on the Preferred Securities, the Debentures, or on the
maturing quarterly interest strips of the Treasury Portfolio, as applicable,
receiving payments of Contract Adjustment Payments, performance of the Purchase
Contracts and for all other purposes whatsoever, whether or not any
distributions on the Preferred Securities, the Debentures, Treasury Portfolio or
the Contract Adjustment Payments payable in respect of the Purchase Contracts
constituting a part of the Corporate PIES or Treasury PIES evidenced thereby
shall be overdue and notwithstanding any notice to the contrary, and neither the
Company nor the Agent, nor any agent of the Company or the Agent, shall be
affected by notice to the contrary.

          Notwithstanding the foregoing, with respect to any Global Certificate,
nothing herein shall prevent the Company, the Agent or any agent of the Company
or the Agent, from giving effect to any written certification, proxy or other
authorization furnished by any Clearing Agency (or its nominee), as a Holder,
with respect to such Global Certificate or impair, as between such Clearing
Agency and owners of beneficial interests in such Global Certificate, the
operation of customary practices governing the exercise of rights of such
Clearing Agency (or its nominee) as Holder of such Global Certificate.

Section 3.12.  Cancellation.

          All Certificates surrendered for delivery of shares of Common Stock on
or after the Purchase Contract Settlement Date, upon the transfer of Preferred
Securities, Debentures, the appropriate Applicable Ownership Interest (as

          If the Company or any Affiliate of the Company shall acquire any
Certificate, such acquisition shall not operate as a cancellation of such
Certificate unless and until such Certificate is delivered to the Agent
cancelled or for cancellation.

Section 3.13.  Substitution of Securities.

          A Holder may separate the Preferred Securities, the Debentures or the
appropriate Applicable Ownership Interest of the Treasury Portfolio, as
applicable, from the related Purchase Contracts in respect of a Corporate PIES
by substituting for such Preferred Securities, Debentures or the appropriate
Applicable Ownership Interest of the Treasury Portfolio, as the case may be,
Treasury Securities in an aggregate principal amount equal to the aggregate
liquidation amount of such Preferred Securities, the aggregate principal amount
of such Debentures or the appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio, as applicable (a "Collateral Substitution"), at any time from and
after the date of this Agreement and on or prior to the seventh Business Day
immediately preceding the Purchase Contract Settlement Date in the case of the
Preferred Securities and the Debentures and on or prior to the second Business
Day immediately preceding the Purchase Contract Settlement Date in the case of
the appropriate Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, in each case by (a)
depositing with the Securities Intermediary Treasury Securities having an
aggregate principal amount equal to the aggregate liquidation amount of the
Preferred Securities or the aggregate principal amount of the Debentures
comprising part of such Corporate PIES or the appropriate Applicable Ownership
Interest (as specified in clause (A) of the definition of such term) of the
Treasury Portfolio comprising part of such Corporate PIES, as the case may be,
and (b) transferring the related Corporate PIES to the Agent accompanied by a
notice to the Agent, substantially in the form of Exhibit C hereto, stating that
the Holder has transferred the relevant amount of Treasury Securities to the
Securities Intermediary and requesting that the Agent instruct the Collateral
Agent to release the Preferred Securities, the Debentures or the appropriate
Applicable Ownership Interest (as specified in clause (A) of the definition of
such term) of the Treasury Portfolio, as the case may be, underlying such
Corporate PIES, whereupon the Agent shall promptly give such instruction to the
Collateral Agent, substantially in the form of Exhibit A to the Pledge
Agreement. Upon receipt of the Treasury Securities described in clause (a) above
and the instruction described in clause (b) above, in accordance with the terms
of the Pledge Agreement, the Collateral Agent will cause the Securities
Intermediary to release to the Agent, on behalf of the Holder, Preferred
Securities, Debentures or the appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio, as the case may be, having a corresponding aggregate liquidation
amount of such Preferred Securities, aggregate principal amount of such
Debentures, or the appropriate Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) of the Treasury Portfolio, as the
case may be, from the Pledge, free and clear of the Company's security interest
therein, and upon receipt thereof the Agent shall promptly:

                (i) cancel the related Corporate PIES;




                                      -25-


<PAGE>   31



               (ii) transfer the Preferred Securities, the Debentures or the
          appropriate Applicable Ownership Interest of the Treasury Portfolio,
          as the case may be, to the Holder; and

              (iii) authenticate, execute on behalf of such Holder and deliver
          a Treasury PIES Certificate executed by the Company in accordance with
          Section 3.3 evidencing the same number of Purchase Contracts as were
          evidenced by the cancelled Corporate PIES.

          Holders who elect to separate the Preferred Securities, the Debentures
or the appropriate Applicable Ownership Interest of the Treasury Portfolio, as
the case may be, from the related Purchase Contract and to substitute Treasury
Securities for such Preferred Securities or Debentures or the appropriate
Applicable Ownership Interest (as specified in clause (A) of the definition of
such term) of the Treasury Portfolio, as the case may be, shall be responsible
for any fees or expenses payable to the Collateral Agent for its services as
Collateral Agent in respect of the substitution, and the Company shall not be
responsible for any such fees or expenses.

          Holders may make Collateral Substitutions (i) only in integral
multiples of 20 Corporate PIES if Treasury Securities are being substituted for
Preferred Securities or Debentures, or (ii) only in integral multiples of
160,000 Corporate PIES if Treasury Securities are being substituted for the
appropriate Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio.

          In the event a Holder making a Collateral Substitution pursuant to
this Section 3.13 fails to effect a book-entry transfer of the Corporate PIES or
fails to deliver a Corporate PIES Certificate(s) to the Agent after depositing
Treasury Securities with the Collateral Agent, the Preferred Securities, the
Debentures or the appropriate Applicable Ownership Interest of the Treasury
Portfolio, as the case may be, constituting a part of such Corporate PIES, and
any distributions on such Preferred Securities, Debentures or the Applicable
Ownership Interest of the Treasury Portfolio, as the case may be, shall be held
in the name of the Agent or its nominee in trust for the benefit of such Holder,
until such Corporate PIES is so transferred or the Corporate PIES Certificate is
so delivered, as the case may be, or, with respect to a Corporate PIES
Certificate, such Holder provides evidence satisfactory to the Company and the
Agent that such Corporate PIES Certificate has been destroyed, lost or stolen,
together with any indemnity that may be required by the Agent and the Company.

          Except as described in this Section 3.13, for so long as the Purchase
Contract underlying a Corporate PIES remains in effect, such Corporate PIES
shall not be separable into its constituent parts, and the rights and
obligations of the Holder in respect of the Preferred Securities, the Debentures
or the appropriate Applicable Ownership Interest of the Treasury Portfolio, as
the case may be, and the Purchase Contract comprising such Corporate PIES may be
acquired, and may be transferred and exchanged, only as a Corporate PIES.

Section 3.14.  Reestablishment of Corporate PIES.

          A Holder of a Treasury PIES may recreate Corporate PIES at any time
(i) on or prior to the seventh Business Day immediately preceding the Purchase
Contract Settlement Date, if a Tax


                                      -26-


<PAGE>   32



Event Redemption has not occurred, and (ii) on or prior to the second Business
Day immediately preceding the Purchase Contract Settlement Date, if a Tax Event
Redemption has occurred, in each case by (a) depositing with the Securities
Intermediary Preferred Securities, Debentures or the appropriate Applicable
Ownership Interest (as defined in clause (A) of the definition of such term) of
the Treasury Portfolio, as the case may be, having an aggregate liquidation
amount in the case of the Preferred Securities, an aggregate principal amount in
the case of the Debentures or an aggregate Applicable Ownership Interest (as
defined in clause (A) of the definition of such term) of the Treasury Portfolio,
as the case may be, equal to the aggregate principal amount at maturity of the
Treasury Securities comprising part of the Treasury PIES and (b) transferring
the related Treasury PIES to the Agent accompanied by a notice to the Agent,
substantially in the form of Exhibit C hereto, stating that the Holder has
transferred the relevant amount of Preferred Securities, Debentures or the
appropriate Applicable Ownership Interest (as defined in clause (A) of the
definition of such term) of the Treasury Portfolio, as the case may be, to the
Securities Intermediary and requesting that the Agent instruct the Collateral
Agent to release the Treasury Securities underlying such Treasury PIES,
whereupon the Agent shall promptly give such instruction to the Collateral
Agent, substantially in the form of Exhibit C to the Pledge Agreement. Upon
receipt of the Preferred Securities, the Debentures or the appropriate
Applicable Ownership Interest (as defined in clause (A) of the definition of
such term) of the Treasury Portfolio, as the case may be, described in clause
(a) above and the instruction described in clause (b) above, in accordance with
the terms of the Pledge Agreement, the Collateral Agent will cause the
Securities Intermediary to effect the release of the Treasury Securities having
a corresponding aggregate principal amount at maturity from the Pledge to the
Agent free and clear of the Company's security interest therein, and upon
receipt thereof the Agent shall promptly:

                (i) cancel the related Treasury PIES;

               (ii) transfer the Treasury Securities to the Holder; and

              (iii) authenticate, execute on behalf of such Holder and deliver
          a Corporate PIES Certificate executed by the Company in accordance
          with Section 3.3 evidencing the same number of Purchase Contracts as
          were evidenced by the cancelled Treasury PIES.

          Holders who elect to recreate Corporate PIES shall be responsible for
any fees or expenses payable to the Collateral Agent for its services as
Collateral Agent in respect of the substitution, and the Company shall not be
responsible for any such fees or expenses.

          Holders of Treasury PIES may reestablish Corporate PIES in integral
multiples of 20 Treasury PIES for 20 Corporate PIES if a Tax Event Redemption
has not occurred, and in integral multiples of 160,000 Treasury PIES for 160,000
Corporate PIES if a Tax Event Redemption has occurred.

          Except as provided in this Section 3.14, for so long as the Purchase
Contract underlying a Treasury PIES remains in effect, such Treasury PIES shall
not be separable into its constituent parts and the rights and obligations of
the Holder of such Treasury PIES in respect of the 1/20 of



                                      -27-


<PAGE>   33



a Treasury Security and the Purchase Contract comprising such Treasury PIES may
be acquired, and may be transferred and exchanged, only as a Treasury PIES.

Section 3.15.  Transfer of Collateral upon Occurrence of Termination Event.

          Upon the occurrence of a Termination Event and the transfer to the
Agent of the Preferred Securities, the Debentures, the appropriate Applicable
Ownership Interest of the Treasury Portfolio or the Treasury Securities, as the
case may be, underlying the Corporate PIES and the Treasury PIES pursuant to the
terms of the Pledge Agreement, the Agent shall request transfer instructions
with respect to such Preferred Securities or Debentures or the appropriate
Applicable Ownership Interest of the Treasury Portfolio or Treasury Securities,
as the case may be, from each Holder by written request, substantially in the
form of Exhibit D hereto, mailed to such Holder at its address as it appears in
the Corporate PIES Register or the Treasury PIES Register, as the case may be.
Upon book-entry transfer of the Corporate PIES or Treasury PIES or delivery of a
Corporate PIES Certificate or Treasury PIES Certificate to the Agent with such
transfer instructions, the Agent shall transfer the Preferred Securities, the
Debentures, the appropriate Applicable Ownership Interest of the Treasury
Portfolio or Treasury Securities, as the case may be, underlying such Corporate
PIES or Treasury PIES, as the case may be, to such Holder by book-entry
transfer, or other appropriate procedures, in accordance with such instructions.
In the event a Holder of Corporate PIES or Treasury PIES fails to effect such
transfer or delivery, the Preferred Securities, the Debentures, the appropriate
Applicable Ownership Interest of the Treasury Portfolio or Treasury Securities,
as the case may be, underlying such Corporate PIES or Treasury PIES, as the case
may be, and any distributions thereon, shall be held in the name of the Agent or
its nominee in trust for the benefit of such Holder, until the earlier of (a)
such Corporate PIES or Treasury PIES are transferred or the Corporate PIES
Certificate or Treasury PIES Certificate is surrendered or such Holder provides
satisfactory evidence that such Corporate PIES Certificate or Treasury PIES
Certificate has been destroyed, lost or stolen, together with any indemnity that
may be required by the Agent and the Company and (b) the expiration of the time
period specified in the abandoned property laws of the relevant State.

Section 3.16.  No Consent to Assumption.

          Each Holder of a Security, by acceptance thereof, shall be deemed
expressly to have withheld any consent to the assumption under Section 365 of
the Bankruptcy Code or otherwise, of the Purchase Contract by the Company or its
trustee, receiver, liquidator or a person or entity performing similar functions
in the event that the Company becomes the debtor under the Bankruptcy Code or
subject to other similar state or federal law providing for reorganization or
liquidation.

Section 4.1.   Payment of Distribution; Rights to Distributions Preserved;
               Distribution Rate Reset; Notice.

          A distribution on any Preferred Security, any Debenture or on the
appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case
may be, which is paid on any Payment Date shall, subject to receipt thereof by
the Agent from the Collateral Agent as provided by the terms of the Pledge
Agreement, be paid to the Person in whose name the Corporate PIES Certificate
(or one or more Predecessor Corporate PIES Certificates) of which such Preferred
Security, such Debenture or the appropriate Applicable Ownership Interest of the
Treasury Portfolio, as the case may be, is a part is registered at the close of
business on the Record Date for such Payment Date.

          Each Corporate PIES Certificate evidencing Preferred Securities or
Debentures delivered under this Agreement upon registration of transfer of or in
exchange for or in lieu of any other Corporate PIES Certificate shall carry the
rights to distributions accrued and unpaid, and to accrue distributions, which
were carried by the Preferred Securities or Debentures or the appropriate
Applicable Ownership Interest of the Treasury Portfolio underlying such other
Corporate PIES Certificate.

          In the case of any Corporate PIES with respect to which Cash
Settlement of the underlying Purchase Contract is effected on or prior to the
fifth Business Day immediately preceding the Purchase Contract Settlement Date
pursuant to prior notice, or with respect to which Early Settlement of the
underlying Purchase Contract is effected on an Early Settlement Date, or with
respect to which a Collateral Substitution is effected, in each case on a date
that is after any Record Date and on or prior to the next succeeding Payment
Date, distributions on the Preferred Securities, the Debentures or on the
appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case
may be, underlying such Corporate PIES otherwise payable on such Payment Date
shall be payable on such Payment Date notwithstanding such Cash Settlement or
Early Settlement or Collateral Substitution, and such distributions shall,
subject to receipt thereof by the Agent, be payable to the Person in whose name
the Corporate PIES Certificate (or one or more Predecessor Corporate PIES
Certificates) was registered at the close of business on the Record Date. Except
as otherwise expressly provided in the immediately preceding sentence, in the
case of any Corporate PIES with respect to which Cash Settlement or Early
Settlement of the underlying Purchase Contract is effected on or prior to the
fifth Business Day immediately preceding the Purchase Contract Settlement Date
or an Early Settlement Date, as the case may be, or with respect to which a
Collateral Substitution has been effected, distributions on the related
Preferred Securities or Debentures or on the appropriate Applicable Ownership
Interest of the Treasury Portfolio, as the case may be, that would otherwise be
payable after the Purchase Contract Settlement Date or Early Settlement Date
shall not be payable hereunder to the Holder of such Corporate PIES; provided,
however, that to the extent that such Holder continues to hold the separated
Preferred Securities or Debentures that formerly


                                      -29-


<PAGE>   35



comprised a part of such Holder's Corporate PIES, such Holder shall be entitled
to receive the distributions on such separated Preferred Securities or
Debentures.

          The applicable Coupon Rate on the Debentures on and after the Purchase
Contract Settlement Date shall be reset on the third Business Day immediately
preceding the Purchase Contract Settlement Date equal to the Reset Rate (such
Reset Rate to be in effect on and after the Purchase Contract Settlement Date).

          Not later than 15 calendar days nor more than 30 calendar days prior
to the third Business Day immediately preceding the Purchase Contract Settlement
Date, the Company shall request DTC (or any successor Clearing Agency), to
notify the Beneficial Owners or Clearing Agency Participants holding Corporate
PIES or Treasury PIES of the procedures to be followed by Holders of Corporate
PIES who intend to effect the settlement of their obligations under the Purchase
Contracts underlying such Corporate PIES with separate cash on or prior to the
fifth Business Day prior to the Purchase Contract Settlement Date.

Section 4.2.   Notice and Voting.

          Under the terms of the Pledge Agreement, the Agent will be entitled to
exercise the voting and any other consensual rights pertaining to the Pledged
Preferred Securities or Pledged Debentures, as the case may be, but only to the
extent instructed in writing by the Holders as described below. Upon receipt of
notice of any meeting at which holders of Preferred Securities or Debentures are
entitled to vote or upon any solicitation of consents, waivers or proxies of
holders of Preferred Securities or Debentures, the Agent shall, as soon as
practicable thereafter, mail to the Holders of Corporate PIES a notice (a)
containing such information as is contained in the notice or solicitation, (b)
stating that each Holder on the record date set by the Agent therefor (which, to
the extent possible, shall be the same date as the record date for determining
the holders of Preferred Securities or Debentures, as the case may be, entitled
to vote) shall be entitled to instruct the Agent as to the exercise of the
voting rights pertaining to such Preferred Securities or Debentures underlying
their Corporate PIES and (c) stating the manner in which such instructions may
be given. Upon the written request of the Holders of Corporate PIES on such
record date received by the Agent at least six days prior to such meeting, the
Agent shall endeavor insofar as practicable to vote or cause to be voted, in
accordance with the instructions set forth in such requests, the maximum number
of Preferred Securities or Debentures, as the case may be, as to which any
particular voting instructions are received. In the absence of specific
instructions from the Holder of a Corporate PIES, the Agent shall abstain from
voting the Preferred Securities or Debentures underlying such Corporate PIES.
The Company hereby agrees, if applicable, to solicit Holders of Corporate PIES
to timely instruct the Agent in order to enable the Agent to vote such Preferred
Securities or Debentures and the Trust shall covenant to such effect in the
Declaration.

Section 4.3.   Distribution of Debentures; Tax Event Redemption.

          Upon the liquidation of the Trust in accordance with the Declaration,
a principal amount at maturity of Debentures constituting the assets of the
Trust and underlying the Preferred Securities equal to the aggregate liquidation
amount of the Pledged Preferred Securities shall be


                                      -30-


<PAGE>   36



delivered to the Securities Intermediary in exchange for the Pledged Preferred
Securities. Thereafter, the Debentures will be substituted for the Pledged
Preferred Securities as the Collateral, and will be held by the Securities
Intermediary in the Collateral Account in accordance with the terms of the
Pledge Agreement to secure the obligations of each Holder of a Corporate PIES to
purchase the Common Stock of the Company under the Purchase Contracts
constituting a part of such Corporate PIES. Following the liquidation of the
Trust, the Holders and the Collateral Agent shall have such security interests,
rights and obligations with respect to the Debentures as the Holders and the
Collateral Agent had in respect of the Preferred Securities subject to the
Pledge thereof as provided in Articles II, III, IV, V and VI of the Pledge
Agreement. The Company may cause to be made in any Corporate PIES Certificates
thereafter to be issued such change in phraseology and form (but not in
substance) as may be appropriate to reflect the liquidation of the Trust and the
substitution of Debentures for Preferred Securities as Collateral.

          Upon the occurrence of a Tax Event Redemption prior to the Purchase
Contract Settlement Date, the Redemption Price payable on the Tax Event
Redemption Date with respect to the Applicable Principal Amount shall be
deposited in the Collateral Account in exchange for the Pledged Preferred
Securities or the Pledged Debentures. Thereafter, pursuant to the terms of the
Pledge Agreement, the Collateral Agent shall cause the Securities Intermediary
to apply an amount equal to the Redemption Amount of such Redemption Price to
purchase on behalf of the Holders of Corporate PIES the Treasury Portfolio and
promptly remit the remaining portion of such Redemption Price, if any, to the
Agent for payment to the Holders of such Corporate PIES. The Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio will be substituted as Collateral for the Pledged
Preferred Securities or the Pledged Debentures, and will be held by the
Collateral Agent in accordance with the terms of the Pledge Agreement to secure
the obligation of each Holder of a Corporate PIES to purchase the Common Stock
of the Company under the Purchase Contract constituting a part of such Corporate
PIES. The Applicable Ownership Interest (as specified in clause (B) of the
definition of such term) of the Treasury Portfolio shall be transferred by the
Securities Intermediary to the Purchase Contract Agent, free and clear of any
lien, pledge or security interest created by the Pledge Agreement. Following the
occurrence of a Tax Event Redemption prior to the Purchase Contract Settlement
Date, the Holders of Corporate PIES and the Collateral Agent shall have such
security interest rights and obligations with respect to the Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio as the Holders of Corporate PIES and the Collateral
Agent had in respect of the Preferred Securities or Debentures, as the case may
be, subject to the Pledge thereof as provided in Articles II, III, IV, V, and VI
of the Pledge Agreement, and any reference herein to the Preferred Securities or
the Debentures shall be deemed to be reference to such Treasury Portfolio. The
Company may cause to be made in any Corporate PIES Certificates thereafter to be
issued such change in phraseology and form (but not in substance) as may be
appropriate to reflect the liquidation of the Trust and the substitution of the
Applicable Ownership Interest (as specified in clause (A) of the definition of
such term) of the Treasury Portfolio for Preferred Securities or Debentures as
Collateral.

                             The Purchase Contracts

Section 5.1.   Purchase of Shares of Common Stock.

          Each Purchase Contract shall, unless an Early Settlement has occurred
in accordance with Section 5.9 hereof, obligate the Holder of the related
Security to purchase, and the Company to sell, on the Purchase Contract
Settlement Date at a price equal to the Stated Amount (the "Purchase Price"), a
number of newly issued shares of Common Stock equal to the Settlement Rate
unless, on or prior to the Purchase Contract Settlement Date, there shall have
occurred a Termination Event with respect to the Security of which such Purchase
Contract is a part. The "Settlement Rate" is equal to (a) if the Applicable
Market Value (as defined below) is equal to or greater than $31.0500 (the
"Threshold Appreciation Price"), 1.6103 shares of Common Stock per Purchase
Contract, (b) if the Applicable Market Value is less than the Threshold
Appreciation Price, but is greater than $26.3125, the number of shares of Common
Stock equal to the Stated Amount divided by the Applicable Market Value and (c)
if the Applicable Market Value is less than or equal to $26.3125, 1.9002 share
of Common Stock per Purchase Contract, in each case subject to adjustment as
provided in Section 5.6 (and in each case rounded upward or downward to the
nearest 1/10,000th of a share). As provided in Section 5.10, no fractional
shares of Common Stock will be issued upon settlement of Purchase Contracts.

          The "Applicable Market Value" means the average of the Closing Price
per share of Common Stock on each of the 20 Trading Days ending on the third
Trading Day immediately preceding the Purchase Contract Settlement Date. The
"Closing Price" of the Common Stock on any date of determination means (i) the
closing sale price (or, if no closing price is reported, the last reported sale
price) of the Common Stock on the New York Stock Exchange (the "NYSE") on such
date, (ii) if the Common Stock is not listed for trading on the NYSE on any such
date, the closing sale price as reported in the composite transactions for the
principal United States securities exchange on which the Common Stock is so
listed, (iii) if the Common Stock is not so listed on a United States national
or regional securities exchange, the closing sale price as reported by The
Nasdaq Stock Market, (iv) if the Common Stock is not so reported, the last
quoted bid price for the Common Stock in the over-the-counter market as reported
by the National Quotation Bureau or similar organization, or (v) if such bid
price is not available, the average of the mid-point of the last bid and ask
prices of the Common Stock on such date from at least three nationally
recognized independent investment banking firms retained for this purpose by the
Company. A "Trading Day" means a day on which the Common Stock (A) is not
suspended from trading on any national or regional securities exchange or
association or over-the-counter market at the close of business and (B) has
traded at least once on the national or regional securities exchange or
association or over-the-counter market that is the primary market for the
trading of the Common Stock.

          Each Holder of a Corporate PIES or a Treasury PIES, by its acceptance
thereof, irrevocably authorizes the Agent to enter into and perform the related
Purchase Contract on its behalf as its attorney-in-fact (including the execution
of Certificates on behalf of such Holder),


                                      -32-


<PAGE>   38



agrees to be bound by the terms and provisions thereof, covenants and agrees to
perform its obligations under such Purchase Contracts, and consents to the
provisions hereof, irrevocably authorizes the Agent as its attorney-in-fact to
enter into and perform this Agreement and the Pledge Agreement on its behalf as
its attorney-in-fact, and consents to and agrees to be bound by the Pledge of
the Preferred Securities, the Debentures, the Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio or the Treasury Securities pursuant to the Pledge Agreement; provided
that upon a Termination Event, the rights of the Holder of such Security under
the Purchase Contract may be enforced without regard to any other rights or
obligations. Each Holder of a Corporate PIES or a Treasury PIES, by its
acceptance thereof, further covenants and agrees, that to the extent and in the
manner provided in Section 5.4 and the Pledge Agreement, but subject to the
terms thereof, payments in respect of the Preferred Securities or the Debentures
or the Proceeds of the Treasury Securities or the Applicable Ownership Interest
(as specified in clause (A) of the definition of such term) of the Treasury
Portfolio on the Purchase Contract Settlement Date shall be paid by the
Collateral Agent to the Company in satisfaction of such Holder's obligations
under such Purchase Contract and such Holder shall acquire no right, title or
interest in such payments.

          Upon registration of transfer of a Certificate, the transferee shall
be bound (without the necessity of any other action on the part of such
transferee) by the terms of this Agreement, the Purchase Contracts underlying
such Certificate and the Pledge Agreement and the transferor shall be released
from the obligations under this Agreement, the Purchase Contracts underlying the
Certificates so transferred and the Pledge Agreement. The Company covenants and
agrees, and each Holder of a Certificate, by its acceptance thereof, likewise
covenants and agrees, to be bound by the provisions of this paragraph.

Section 5.2.   Contract Adjustment Payments.

          The Company shall pay, on each Payment Date, the Contract Adjustment
Payments payable in respect of each Purchase Contract to the Person in whose
name a Certificate (or one or more Predecessor Certificates) is registered at
the close of business on the Record Date next preceding such Payment Date. The
Contract Adjustment Payments will be payable at the office of the Agent in The
City of New York maintained for that purpose or, at the option of the Company,
by check mailed to the address of the Person entitled thereto at such Person's
address as it appears on the Corporate PIES Register or Treasury PIES Register.
If any date on which Contract Adjustment Payments are to be made on the Purchase
Contracts related to the PIES is not a Business Day, then payment of the
Contract Adjustment Payments payable on such date will be made on the next day
that is a Business Day (and without any interest in respect of any such delay),
except that, if such Business Day is in the next calendar year, such payment
will be made on the preceding Business Day.

          Upon the occurrence of a Termination Event, the Company's obligation
to pay Contract Adjustment Payments (including any accrued Contract Adjustment
Payments) shall cease.

          Each Certificate delivered under this Agreement upon registration of
transfer of or in exchange for or in lieu of (including as a result of a

Adjustment Payments accrued and unpaid, and to accrue Contract Adjustment
Payments, which were carried by the Purchase Contracts underlying such other
Certificates.

          Subject to Section 5.9, in the case of any Security with respect to
which Early Settlement of the underlying Purchase Contract is effected on an
Early Settlement Date that is after any Record Date and on or prior to the next
succeeding Payment Date, Contract Adjustment Payments, if any, otherwise payable
on such Payment Date shall be payable on such Payment Date notwithstanding such
Early Settlement, and such Contract Adjustment Payments shall be paid to the
Person in whose name the Certificate evidencing such Security (or one or more
Predecessor Certificates) is registered at the close of business on such Record
Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Security with respect to which Early Settlement of
the underlying Purchase Contract is effected on an Early Settlement Date,
Contract Adjustment Payments that would otherwise be payable after the Early
Settlement Date with respect to such Purchase Contract shall not be payable.

Section 5.3.   [Intentionally omitted].

Section 5.4.   Payment of Purchase Price.

          (a) (i) Unless a Tax Event Redemption has occurred or a Holder settles
the underlying Purchase Contract through the early delivery of cash to the
Purchase Contract Agent in the manner described in Section 5.9, each Holder of a
Corporate PIES who intends to pay in cash shall notify the Agent by use of a
notice in substantially the form of Exhibit E hereto of its intention to pay in
cash ("Cash Settlement") the Purchase Price for the shares of Common Stock to be
purchased pursuant to a Purchase Contract. Such notice shall be given prior to
5:00 p.m., New York City time, on the seventh Business Day immediately preceding
the Purchase Contract Settlement Date. Prior to 11:00 a.m., New York City time,
on the next succeeding Business Day, the Agent shall notify the Collateral Agent
and the Indenture Trustee of the receipt of such notices from Holders intending
to make a Cash Settlement.

             (ii) A Holder of a Corporate PIES who has so notified the Agent
of its intention to make a Cash Settlement shall pay the Purchase Price to the
Securities Intermediary for deposit in the Collateral Account prior to 11:00
a.m., New York City time, on the fifth Business Day immediately preceding the
Purchase Contract Settlement Date in lawful money of the United States by
certified or cashiers' check or wire transfer, in each case in immediately
available funds payable to or upon the order of the Securities Intermediary. Any
cash received by the Collateral Agent shall be invested promptly by the
Securities Intermediary in Permitted Investments and paid to the Company on the
Purchase Contract Settlement Date in settlement of the Purchase Contract in
accordance with the terms of this Agreement and the Pledge Agreement. Any funds
received by the Securities Intermediary in respect of the investment earnings
from the investment in such Permitted Investments, shall be distributed to the
Agent when received for payment to the Holder of the related Corporate PIES.

            (iii) If a Holder of a Corporate PIES fails to notify the Agent
of its intention to make a Cash Settlement in accordance with paragraph (a)(i)
above, or does notify the Agent as provided in paragraph (a)(i) above of its
intention to pay the Purchase Price in cash, but fails to make such


                                      -34-


<PAGE>   40



payment as required by paragraph (a)(ii) above, such Holder shall be deemed to
have consented to the disposition of the Pledged Preferred Securities or the
Pledged Debentures pursuant to the Remarketing as described in paragraph (b)
below.

             (iv) Promptly after 11:00 a.m., New York City time, on the fifth
Business Day preceding the Purchase Contract Settlement Date, the Agent, based
on notices received by the Agent pursuant to Section 5.4(a) hereof and notice
from the Securities Intermediary regarding cash received by it prior to such
time, shall notify the Collateral Agent and the Indenture Trustee of the number
of Preferred Securities or Debentures to be tendered for purchase in the
Remarketing in a notice substantially in the form of Exhibit F hereto.

          (b)     In order to dispose of the Preferred Securities or Debentures,
as the case may be, of Corporate PIES Holders who have not notified the Agent of
their intention to effect a Cash Settlement as provided in paragraph (a)(i)
above, or who have so notified the Agent but fail to make such payment as
required by paragraph (a)(ii) above, the Company shall engage Lehman Brothers,
Inc. (the "Remarketing Agent") pursuant to the Remarketing Agreement to sell
such Preferred Securities or Debentures. In order to facilitate the remarketing,
the Agent, based on the notices specified in Section 5.4(a)(iv), shall notify
the Remarketing Agent, promptly after 11:00 a.m., New York City time, on the
fifth Business Day immediately preceding the Purchase Contract Settlement Date,
of the aggregate number of Preferred Securities or Debentures that are a
component of Corporate PIES to be remarketed. Concurrently, the Collateral
Agent, pursuant to the terms of the Pledge Agreement, shall cause such Preferred
Securities or Debentures to be presented to the Remarketing Agent for
remarketing. Upon receipt of such notice from the Agent and such Preferred
Securities or Debentures, the Remarketing Agent shall, on the third Business Day
immediately preceding the Purchase Contract Settlement Date, use commercially
reasonable efforts to remarket such Preferred Securities or Debentures on such
date at a price of 100% of the aggregate stated liquidation amount of such
Preferred Securities or principal amount at maturity of such Debentures. The
proceeds equal thereto shall automatically be applied by the Collateral Agent,
in accordance with the Pledge Agreement, to satisfy in full such Corporate PIES
Holders' obligations to pay the Purchase Price for the Common Stock under the
related Purchase Contracts on the Purchase Contract Settlement Date. Corporate
PIES Holders whose Preferred Securities or Debentures are so remarketed shall
not be responsible for the payment of any remarketing fee in connection
therewith. If, in spite of using their reasonable efforts, the Remarketing Agent
cannot remarket the related Preferred Securities or Debentures of such Holders
of Corporate PIES at a price of 100% of the aggregate stated liquidation amount
of such Preferred Securities or principal amount at maturity of such Debentures,
the remarketing shall be deemed to have failed (a "Failed Remarketing") and in
accordance with the terms of the Pledge Agreement the Collateral Agent, for the
benefit of the Company, shall exercise its rights as a secured party with
respect to such Preferred Securities or Debentures, including those actions
specified in paragraph (c) below; provided, that if upon a Failed Remarketing
the Collateral Agent exercises such rights for the benefit of the Company with
respect to such Preferred Securities or Debentures, any accrued and unpaid
distributions on such Preferred Securities or Debentures shall become payable by
the Company to the Agent for payment to the Beneficial Owner of the Corporate
PIES to which such Preferred Securities or Debentures relate. The Company shall
cause a notice of such Failed Remarketing to be published on the second Business
Day immediately preceding the Purchase Contract Settlement Date in a daily
newspaper

                                      -35-

in the English language of general circulation in The City of New York, which is
expected to be The Wall Street Journal.

          (c)     With respect to any Preferred Securities or Debentures which
are subject to a Failed Remarketing, the Collateral Agent for the benefit of the
Company reserves all of its rights as a secured party with respect thereto and,
subject to applicable law and paragraph (g) below, may, among other things, (i)
retain the Preferred Securities or Debentures in full satisfaction of the
Holders' obligations under the Purchase Contracts or (ii) sell the Preferred
Securities or Debentures in one or more public or private sales.

          (d) (i) Unless a Holder of Treasury PIES or Corporate PIES (if a Tax
Event Redemption has occurred) settles the underlying Purchase Contract through
the early delivery of cash to the Purchase Contract Agent in the manner
described in Section 5.9, each Holder of a Treasury PIES or Corporate PIES (if a
Tax Event Redemption has occurred) who intends to pay in cash shall notify the
Agent by use of a notice in substantially the form of Exhibit E hereto of its
intention to pay in cash the Purchase Price for the shares of Common Stock to be
purchased pursuant to a Purchase Contract. Such notice shall be given on or
prior to 5:00 p.m., New York City time, on the second Business Day immediately
preceding the Purchase Contract Settlement Date.

             (ii) A Holder of a Treasury PIES or Corporate PIES (if a Tax Event
Redemption has occurred) who has so notified the Agent of its intention to make
a Cash Settlement in accordance with paragraph (d)(i) above shall pay the
Purchase Price to the Securities Intermediary for deposit in the Collateral
Account prior to 11:00 a.m., New York City time, on the Business Day immediately
preceding the Purchase Contract Settlement Date in lawful money of the United
States by certified or cashiers' check or wire transfer, in each case in
immediately available funds payable to or upon the order of the Securities
Intermediary. Any cash received by the Collateral Agent shall be invested
promptly by the Securities Intermediary in Permitted Investments and paid to the
Company on the Purchase Contract Settlement Date in settlement of the Purchase
Contract in accordance with the terms of this Agreement and the Pledge
Agreement. Any funds received by the Securities Intermediary in respect of the
investment earnings from the investment in such Permitted Investments shall be
distributed to the Agent when received for payment to the Holder.

            (iii) If a Holder of a Treasury PIES or a Holder of a Corporate PIES
(if a Tax Event Redemption has occurred) fails to notify the Agent of its
intention to make a Cash Settlement in accordance with paragraph (d)(i) above,
or does notify the Agent as provided in paragraph (d)(i) above of its intention
to pay the Purchase Price in cash, but fails to make such payment as required by
paragraph (d)(ii) above, then upon the maturity of the Pledged Treasury
Securities or the appropriate Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) of the Treasury Portfolio, as the
case may be, held by the Securities Intermediary on the Business Day immediately
prior to the Purchase Contract Settlement Date, the principal amount of the
Treasury Securities or the appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio, as the case may be, received by the Securities Intermediary shall be
invested promptly in Permitted Investments. On the Purchase Contract Settlement
Date an amount equal to the Purchase Price shall be remitted to the Company as
payment thereof without receiving any instructions from the Holder. In the event


                                      -36-


<PAGE>   42



the sum of the proceeds from the related Pledged Treasury Securities or the
appropriate Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, as the case may be, and the
investment earnings earned from such investments is in excess of the aggregate
Purchase Price of the Purchase Contracts being settled thereby, the Collateral
Agent shall cause the Securities Intermediary to distribute such excess to the
Agent for the benefit of the Holder of the related Treasury PIES or Corporate
PIES when received.

          (e)  Any distribution to Holders of excess funds and interest
described above shall be payable at the office of the Agent in The City of New
York maintained for that purpose or, at the option of the Holder, by check
mailed to the address of the Person entitled thereto at such address as it
appears on the Register.

          (f)  Upon Cash Settlement of any Purchase Contract, (i) the Collateral
Agent will in accordance with the terms of the Pledge Agreement cause the
Pledged Preferred Securities, the Pledged Debentures, the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio or the Pledged Treasury Securities, as the case may
be, underlying the relevant Security to be released from the Pledge free and
clear of any security interest of the Company and transferred to the Agent for
delivery to the Holder thereof or its designee as soon as practicable and (ii)
subject to the receipt thereof, the Agent shall, by book-entry transfer, or
other appropriate procedures, in accordance with written instructions provided
by the Holder thereof, transfer such Preferred Securities or Debentures, the
appropriate Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio or such Treasury Securities,
as the case may be (or, if no such instructions are given to the Agent by the
Holder, the Agent shall hold such Preferred Securities or Debentures or the
Applicable Ownership Interest (as specified in clause (A) of the definition of
such term) of the Treasury Portfolio or such Treasury Securities, as the case
may be, and any distribution thereon, in the name of the Agent or its nominee in
trust for the benefit of such Holder until the expiration of the time period
specified in the abandoned property laws of the relevant State).

          (g)  The obligations of the Holders to pay the Purchase Price are
non-recourse obligations and, except to the extent paid by Early Settlement or
Cash Settlement, are payable solely out of the proceeds of any Collateral
pledged to secure the obligations of the Holders and in no event will Holders be
liable for any deficiency between the proceeds of the disposition of Collateral
and the Purchase Price.

Section 5.5.   Issuance of Shares of Common Stock.

          Unless a Termination Event or an Early Settlement shall have occurred,
subject to Section 5.6(b), the Company shall issue and deposit with the Agent,
for the benefit of the Holders of the Outstanding Securities, one or more
certificates representing the newly issued shares of Common Stock registered in
the name of the Agent (or its nominee) as custodian for the Holders (such
certificates for shares of Common Stock, together with any dividends or
distributions for which a record date and payment date for such dividend or
distribution has occurred after the Purchase Contract Settlement Date, being
hereinafter referred to as the "Purchase Contract Settlement Fund") to which the
Holders are entitled hereunder. Subject to the foregoing, upon surrender of a


                                      -37-


<PAGE>   43



Certificate to the Agent on or after the Purchase Contract Settlement Date,
together with settlement instructions thereon duly completed and executed, the
Holder of such Certificate shall be entitled to receive in exchange therefor a
certificate representing that number of whole shares of Common Stock which such
Holder is entitled to receive pursuant to the provisions of this Article Five
(after taking into account all Securities then held by such Holder), together
with cash in lieu of fractional shares as provided in Section 5.10 and any
dividends or distributions with respect to such shares constituting part of the
Purchase Contract Settlement Fund, but without any interest thereon, and the
Certificate so surrendered shall forthwith be cancelled. Such shares shall be
registered in the name of the Holder or the Holder's designee as specified in
the settlement instructions provided by the Holder to the Agent. If any shares
of Common Stock issued in respect of a Purchase Contract are to be registered to
a Person other than the Person in whose name the Certificate evidencing such
Purchase Contract is registered, no such registration shall be made unless the
Person requesting such registration has paid any transfer and other taxes
required by reason of such registration in a name other than that of the
registered Holder of the Certificate evidencing such Purchase Contract or has
established to the satisfaction of the Company that such tax either has been
paid or is not payable.

Section 5.6.   Adjustment of Settlement Rate.

          (a)  Adjustments for Dividends, Distributions, Stock Splits, Etc.

               (1) In case the Company shall pay or make a dividend or other
distribution on the Common Stock in Common Stock, the Settlement Rate in effect
at the opening of business on the day following the date fixed for the
determination of stockholders entitled to receive such dividend or other
distribution shall be increased by dividing such Settlement Rate by a fraction
of which the numerator shall be the number of shares of Common Stock outstanding
at the close of business on the date fixed for such determination and the
denominator shall be the sum of such number of shares and the total number of
shares constituting such dividend or other distribution, such increase to become
effective immediately after the opening of business on the day following the
date fixed for such determination. For the purposes of this paragraph (1), the
number of shares of Common Stock at any time outstanding shall not include
shares held in the treasury of the Company but shall include any shares issuable
in respect of any scrip certificates issued in lieu of fractions of shares of
Common Stock. The Company will not pay any dividend or make any distribution on
shares of Common Stock held in the treasury of the Company.

               (2) In case the Company shall issue rights, options or warrants
to all holders of its Common Stock (not being available on an equivalent basis
to Holders of the Securities upon settlement of the Purchase Contracts
underlying such Securities) entitling them, for a period expiring within 45 days
after the record date for the determination of stockholders entitled to receive
such rights, options or warrants, to subscribe for or purchase shares of Common
Stock at a price per share less than the Current Market Price per share of the
Common Stock on the date fixed for the determination of stockholders entitled to
receive such rights, options or warrants (other than pursuant to a dividend
reinvestment plan), the Settlement Rate in effect at the opening of business on
the day following the date fixed for such determination shall be increased by
dividing such Settlement Rate by a fraction of which the numerator shall be the
number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination


                                      -38-


<PAGE>   44



plus the number of shares of Common Stock which the aggregate of the offering
price of the total number of shares of Common Stock so offered for subscription
or purchase would purchase at such Current Market Price and the denominator
shall be the number of shares of Common Stock outstanding at the close of
business on the date fixed for such determination plus the number of shares of
Common Stock so offered for subscription or purchase, such increase to become
effective immediately after the opening of business on the day following the
date fixed for such determination. For the purposes of this paragraph (2), the
number of shares of Common Stock at any time outstanding shall not include
shares held in the treasury of the Company but shall include any shares issuable
in respect of any scrip certificates issued in lieu of fractions of shares of
Common Stock. The Company shall not issue any such rights, options or warrants
in respect of shares of Common Stock held in the treasury of the Company.

               (3) In case outstanding shares of Common Stock shall be
subdivided or split into a greater number of shares of Common Stock, the
Settlement Rate in effect at the opening of business on the day following the
day upon which such subdivision or split becomes effective shall be
proportionately increased, and, conversely, in case outstanding shares of Common
Stock shall each be combined into a smaller number of shares of Common Stock,
the Settlement Rate in effect at the opening of business on the day following
the day upon which such combination becomes effective shall be proportionately
reduced, such increase or reduction, as the case may be, to become effective
immediately after the opening of business on the day following the day upon
which such subdivision, split or combination becomes effective.

               (4) In case the Company shall, by dividend or otherwise,
distribute to all holders of its Common Stock evidences of its indebtedness or
assets (including securities, but excluding any rights or warrants referred to
in paragraph (2) of this Section, any dividend or distribution paid exclusively
in cash and any dividend or distribution referred to in paragraph (1) of this
Section), the Settlement Rate shall be adjusted so that the same shall equal the
rate determined by dividing the Settlement Rate in effect immediately prior to
the close of business on the date fixed for the determination of stockholders
entitled to receive such distribution by a fraction of which the numerator shall
be the Current Market Price per share of the Common Stock on the date fixed for
such determination less the then fair market value (as determined by the Board
of Directors, whose determination shall be conclusive and described in a Board
Resolution) of the portion of the assets or evidences of indebtedness so
distributed applicable to one share of Common Stock and the denominator shall be
such Current Market Price per share of the Common Stock, such adjustment to
become effective immediately prior to the opening of business on the day
following the date fixed for the determination of stockholders entitled to
receive such distribution. In any case in which this paragraph (4) is
applicable, paragraph (2) of this Section shall not be applicable.

               (5) In case the Company shall, by dividend or otherwise,
distribute to all holders of its Common Stock (I) cash (excluding any cash that
is distributed in a Reorganization Event to which Section 5.6(b) applies or as
part of a distribution referred to in paragraph (4) of this Section) in an
aggregate amount that, combined together with the aggregate amount of any other
distributions to all holders of its Common Stock made exclusively in cash (other
than in connection with a Reorganization Event) within the 12 months preceding
the date of payment of such distribution and in respect of which no adjustment
pursuant to this paragraph (5) or


                                      -39-


<PAGE>   45



paragraph (6) of this Section has been made and (II) the aggregate of any cash
plus the fair market value (as determined by the Board of Directors, whose
determination shall be conclusive and described in a Board Resolution) of
consideration payable in respect of any tender or exchange offer by the Company
or any of its subsidiaries for all or any portion of the Common Stock concluded
within the 12 months preceding the date of payment of the distribution described
in Clause (I) above and in respect of which no adjustment pursuant to this
paragraph (5) or paragraph (4) or paragraph (6) of this Section has been made,
exceeds 15% of the product of the Current Market Price per share of the Common
Stock on the date for the determination of holders of shares of Common Stock
entitled to receive such distribution times the number of shares of Common Stock
outstanding on such date, then, and in each such case, immediately after the
close of business on such date for determination, the Settlement Rate shall be
increased so that the same shall equal the rate determined by dividing the
Settlement Rate in effect immediately prior to the close of business on the date
fixed for determination of the stockholders entitled to receive such
distribution by a fraction (i) the numerator of which shall be equal to the
Current Market Price per share of the Common Stock on the date fixed for such
determination less an amount equal to the quotient of (x) the combined amount
distributed or payable in the transactions described in clauses (I) and (II)
above and (y) the number of shares of Common Stock outstanding on such date for
determination and (ii) the denominator of which shall be equal to the Current
Market Price per share of the Common Stock on such date for determination.

               (6) In case a tender or exchange offer made by the Company or any
subsidiary of the Company for all or any portion of the Common Stock shall
expire and such tender or exchange offer (as amended upon the expiration
thereof) shall require the payment to stockholders (based on the acceptance (up
to any maximum specified in the terms of the tender or exchange offer) of
Purchased Shares) of (I) an aggregate consideration having a fair market value
(as determined by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution) that combined together with the
aggregate of the cash plus the fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution), as of the expiration of such tender or exchange offer, of
consideration payable in respect of any other tender or exchange offer, by the
Company or any subsidiary of the Company for all or any portion of the Common
Stock expiring within the 12 months preceding the expiration of such tender or
exchange offer and in respect of which no adjustment pursuant to paragraph (5)
of this Section or this paragraph (6) has been made and (II) the aggregate
amount of any distributions to all holders of the Company's Common Stock made
exclusively in cash within the 12 months preceding the expiration of such tender
or exchange offer and in respect of which no adjustment pursuant to paragraph
(5) of this Section or this paragraph (6) has been made, exceeds 15% of the
product of the Current Market Price per share of the Common Stock as of the last
time (the "Expiration Time") tenders could have been made pursuant to such
tender or exchange offer (as it may be amended) times the number of shares of
Common Stock outstanding (including any tendered shares) on the Expiration Time,
then, and in each such case, immediately prior to the opening of business on the
day after the date of the Expiration Time, the Settlement Rate shall be adjusted
so that the same shall equal the rate determined by dividing the Settlement Rate
immediately prior to the close of business on the date of the Expiration Time by
a fraction (i) the numerator of which shall be equal to (A) the product of (I)
the Current Market Price per share of the Common Stock on the date of the
Expiration

                                      -40-


<PAGE>   46



Time and (II) the number of shares of Common Stock outstanding (including any
tendered shares) on the Expiration Time less (B) the amount of cash plus the
fair market value (determined as aforesaid) of the aggregate consideration
payable to stockholders based on the transactions described in clauses (I) and
(II) above (assuming in the case of clause (I) the acceptance, up to any maximum
specified in the terms of the tender or exchange offer, of Purchased Shares),
and (ii) the denominator of which shall be equal to the product of (A) the
Current Market Price per share of the Common Stock as of the Expiration Time and
(B) the number of shares of Common Stock outstanding (including any tendered
shares) as of the Expiration Time less the number of all shares validly tendered
and not withdrawn as of the Expiration Time (the shares deemed so accepted, up
to any such maximum, being referred to as the "Purchased Shares").

               (7) The reclassification of Common Stock into securities
including securities other than Common Stock (other than any reclassification
upon a Reorganization Event to which Section 5.6(b) applies) shall be deemed to
involve (a) a distribution of such securities other than Common Stock to all
holders of Common Stock (and the effective date of such reclassification shall
be deemed to be "the date fixed for the determination of stockholders entitled
to receive such distribution" and the "date fixed for such determination" within
the meaning of paragraph (4) of this Section), and (b) a subdivision, split or
combination, as the case may be, of the number of shares of Common Stock
outstanding immediately prior to such reclassification into the number of shares
of Common Stock outstanding immediately thereafter (and the effective date of
such reclassification shall be deemed to be "the day upon which such subdivision
or split becomes effective" or "the day upon which such combination becomes
effective", as the case may be, and "the day upon which such subdivision, split
or combination becomes effective" within the meaning of paragraph (3) of this
Section).

               (8) The "Current Market Price" per share of Common Stock on any
day means the average of the daily Closing Prices for the five consecutive
Trading Days selected by the Company commencing not more than 30 Trading Days
before, and ending not later than, the earlier of the day in question and the
day before the "ex date" with respect to the issuance or distribution requiring
such computation. For purposes of this paragraph, the term "ex date", when used
with respect to any issuance or distribution, shall mean the first date on which
the Common Stock trades regular way on such exchange or in such market without
the right to receive such issuance or distribution.

               (9) All adjustments to the Settlement Rate shall be calculated to
the nearest 1/10,000th of a share of Common Stock (or if there is not a nearest
1/10,000th of a share, to the next lower 1/10,000th of a share). No adjustment
in the Settlement Rate shall be required unless such adjustment would require an
increase or decrease of at least one percent thereof; provided, however, that
any adjustments which by reason of this subparagraph are not required to be made
shall be carried forward and taken into account in any subsequent adjustment. If
an adjustment is made to the Settlement Rate pursuant to paragraph (1), (2),
(3), (4), (5), (6), (7) or (10) of this Section 5.6(a), an adjustment shall also
be made to the Applicable Market Value solely to determine which of clauses (a),
(b) or (c) of the definition of Settlement Rate in Section 5.1 will apply on the
Purchase Contract Settlement Date. Such adjustment shall be made by multiplying
the Applicable Market Value by a fraction of which the numerator shall be the
Settlement Rate

                                      -41-


<PAGE>   47



immediately after such adjustment pursuant to paragraph (1), (2), (3), (4), (5),
(6), (7) or (10) of this Section 5.6(a) and the denominator shall be the
Settlement Rate immediately before such adjustment; provided, however, that if
such adjustment to the Settlement Rate is required to be made pursuant to the
occurrence of any of the events contemplated by paragraph (1), (2), (3), (4),
(5), (7) or (10) of this Section 5.6(a) during the period taken into
consideration for determining the Applicable Market Value, appropriate and
customary adjustments shall be made to the Settlement Rate.

               (10) The Company may make such increases in the Settlement Rate,
in addition to those required by this Section, as it considers to be advisable
in order to avoid or diminish any income tax to any holders of shares of Common
Stock resulting from any dividend or distribution of stock or issuance of rights
or warrants to purchase or subscribe for stock or from any event treated as such
for income tax purposes or for any other reason.

          (b)  Adjustment for Consolidation, Merger or Other Reorganization
Event.

               In the event of (i) any consolidation or merger of the Company
with or into another Person (other than a merger or consolidation in which the
Company is the continuing corporation and in which the Common Stock outstanding
immediately prior to the merger or consolidation is not exchanged for cash,
securities or other property of the Company or another corporation), (ii) any
sale, transfer, lease or conveyance to another Person of the property of the
Company as an entirety or substantially as an entirety, (iii) any statutory
exchange of securities of the Company with another Person (other than in
connection with a merger or acquisition) or (iv) any liquidation, dissolution or
winding up of the Company other than as a result of or after the occurrence of a
Termination Event (any such event, a "Reorganization Event"), the Settlement
Rate will be adjusted to provide that each Holder of Securities will receive on
the Purchase Contract Settlement Date with respect to each Purchase Contract
forming a part thereof, the kind and amount of securities, cash and other
property receivable upon such Reorganization Event (without any interest
thereon, and without any right to dividends or distribution thereon which have a
record date that is prior to the Purchase Contract Settlement Date) by a Holder
of the number of shares of Common Stock issuable on account of each Purchase
Contract if the Purchase Contract Settlement Date had occurred immediately prior
to such Reorganization Event assuming such Holder of Common Stock is not a
Person with which the Company consolidated or into which the Company merged or
which merged into the Company or to which such sale or transfer was made, as the
case may be (any such Person, a "Constituent Person"), or an Affiliate of a
Constituent Person to the extent such Reorganization Event provides for
different treatment of Common Stock held by Affiliates of the Company and
non-affiliates and such Holder failed to exercise his rights of election, if
any, as to the kind or amount of securities, cash and other property receivable
upon such Reorganization Event (provided that if the kind or amount of
securities, cash and other property receivable upon such Reorganization Event is
not the same for each share of Common Stock held immediately prior to such
Reorganization Event by other than a Constituent Person or an Affiliate thereof
and in respect of which such rights of election shall not have been exercised
("non-electing share"), then for the purpose of this Section the kind and amount
of securities, cash and other property receivable upon such Reorganization Event
by each non-electing share shall be deemed to be the kind and amount so
receivable per share by a plurality of the non-electing shares). In the event of
such a Reorganization Event, the Person

formed by such consolidation, merger or exchange or the Person which acquires
the assets of the Company or, in the event of a liquidation or dissolution of
the Company, the Company or a liquidating trust created in connection therewith,
shall execute and deliver to the Agent an agreement supplemental hereto
providing that the Holders of each Outstanding Security shall have the rights
provided by this Section 5.6(b). Such supplemental agreement shall provide for
adjustments which, for events subsequent to the effective date of such
supplemental agreement, shall be as nearly equivalent as may be practicable to
the adjustments provided for in this Section. The above provisions of this
Section shall similarly apply to successive Reorganization Events.

Section 5.7.   Notice of Adjustments and Certain Other Events.

          (a)  Whenever the Settlement Rate is adjusted as herein provided, the
Company shall:

                (i) forthwith compute the adjusted Settlement Rate in accordance
          with Section 5.6 and prepare and transmit to the Agent an Officers'
          Certificate setting forth the Settlement Rate, the method of
          calculation thereof in reasonable detail, and the facts requiring such
          adjustment and upon which such adjustment is based; and

               (ii) within 10 Business Days following the occurrence of an event
          that requires an adjustment to the Settlement Rate pursuant to Section
          5.6 (or if the Company is not aware of such occurrence, as soon as
          practicable after becoming so aware), provide a written notice to the
          Holders of the Securities of the occurrence of such event and a
          statement in reasonable detail setting forth the method by which the
          adjustment to the Settlement Rate was determined and setting forth the
          adjusted Settlement Rate.

          (b)  The Agent shall not at any time be under any duty or
responsibility to any Holder of Securities to determine whether any facts exist
which may require any adjustment of the Settlement Rate, or with respect to the
nature or extent or calculation of any such adjustment when made, or with
respect to the method employed in making the same. The Agent shall not be
accountable with respect to the validity or value (or the kind or amount) of any
shares of Common Stock, or of any securities or property, which may at the time
be issued or delivered with respect to any Purchase Contract; and the Agent
makes no representation with respect thereto. The Agent shall not be responsible
for any failure of the Company to issue, transfer or deliver any shares of
Common Stock pursuant to a Purchase Contract or to comply with any of the
duties, responsibilities or covenants of the Company contained in this Article.

Section 5.8.   Termination Event; Notice.

          The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights of the
Holders to receive and the obligation of the Company to pay any Contract
Adjustment Payments, if the Company shall have such obligation, and the rights
and obligations of Holders to purchase Common Stock, shall immediately and
automatically terminate, without the necessity of any notice or action by any
Holder, the Agent or the Company, if, on or prior to the Purchase Contract
Settlement Date, a Termination Event shall have occurred. Upon and after the
occurrence of a Termination Event,

                                      -43-


<PAGE>   49



the Securities shall thereafter represent the right to receive the Preferred
Securities or the Debentures or the appropriate Applicable Ownership Interest of
the Treasury Portfolio, as the case may be, forming a part of such Securities in
the case of Corporate PIES, or Treasury Securities in the case of Treasury PIES,
in accordance with the provisions of Section 5.4 of the Pledge Agreement. Upon
the occurrence of a Termination Event, the Company shall promptly but in no
event later than two Business Days thereafter give written notice to the Agent,
the Collateral Agent and the Holders, at their addresses as they appear in the
Register.

Section 5.9.   Early Settlement.

          (a)  Subject to and upon compliance with the provisions of this
Section 5.9, at the option of the Holder thereof, Purchase Contracts underlying
Securities may be settled early ("Early Settlement") in the case of Corporate
PIES (unless a Tax Event Redemption has occurred) on or prior to the seventh
Business Day immediately preceding the Purchase Contract Settlement Date and in
the case of Treasury PIES on or prior to the second Business Day immediately
preceding the Purchase Contract Settlement Date, in each case, as provided
herein; and if a Tax Event Redemption has occurred and the Treasury Portfolio
has become a component of the Corporate PIES, Purchase Contracts underlying
Corporate PIES may be settled early on or prior to the second Business Day
immediately preceding the Purchase Contract Settlement Date, but only in an
aggregate amount of $8,000,000 or in an integral multiple thereof. In order to
exercise the right to effect Early Settlement with respect to any Purchase
Contracts, the Holder of the Certificate evidencing Securities shall deliver
such Certificate to the Agent at the Corporate Trust Office duly endorsed for
transfer to the Company or in blank with the form of Election to Settle Early on
the reverse thereof duly completed and accompanied by payment (payable to the
Company in immediately available funds) in an amount (the "Early Settlement
Amount") equal to (i) the product of (A) the Stated Amount times (B) the number
of Purchase Contracts with respect to which the Holder has elected to effect
Early Settlement plus (ii) if such delivery is made with respect to any Purchase
Contracts during the period from the close of business on any Record Date next
preceding any Payment Date to the opening of business on such Payment Date, an
amount equal to the sum of (x) the Contract Adjustment Payments payable on such
Payment Date with respect to such Purchase Contracts plus (y) in the case of a
Corporate PIES Certificate, the distributions on the related Preferred
Securities or Debentures payable on such Payment Date. Except as provided in the
immediately preceding sentence and subject to the second to last paragraph of
Section 5.2, no payment or adjustment shall be made upon Early Settlement of any
Purchase Contract on account of any Contract Adjustment Payments accrued on such
Purchase Contract or on account of any dividends on the Common Stock issued upon
such Early Settlement. If the foregoing requirements are first satisfied with
respect to Purchase Contracts underlying any Securities at or prior to 5:00
p.m., New York City time, on a Business Day, such day shall be the "Early
Settlement Date" with respect to such Securities and if such requirements are
first satisfied after 5:00 p.m., New York City time, on a Business Day or on a
day that is not a Business Day, the "Early Settlement Date" with respect to such
Securities shall be the next succeeding Business Day.

          (b)  Upon Early Settlement of Purchase Contracts by a Holder of the
related Securities, the Company shall issue, and the Holder shall be entitled to
receive, 1.6103 shares of Common Stock on account of each Purchase Contract as
to which Early Settlement is effected


                                      -44-


<PAGE>   50



(the "Early Settlement Rate"). The Early Settlement Rate shall be adjusted in
the same manner and at the same time as the Settlement Rate is adjusted.

          (c)  No later than the third Business Day after the applicable Early
Settlement Date the Company shall cause (i) the shares of Common Stock issuable
upon Early Settlement of Purchase Contracts to be issued and delivered, together
with payment in lieu of any fraction of a share, as provided in Section 5.10,
and (ii) the related Preferred Securities or Debentures or the appropriate
Applicable Ownership Interest (as specified in clause (A) of the definition of
such term) of the Treasury Portfolio, in the case of Corporate PIES, or the
related Treasury Securities, in the case of Treasury PIES, to be released from
the Pledge by the Collateral Agent and transferred, in each case, to the Agent
for delivery to the Holder thereof or its designee.

          (d)  Upon Early Settlement of any Purchase Contracts, and subject to
receipt of shares of Common Stock from the Company and the Preferred Securities,
the Debentures, the appropriate Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) of the Treasury Portfolio or Treasury
Securities, as the case may be, from the Securities Intermediary, as applicable,
the Agent shall, in accordance with the instructions provided by the Holder
thereof on the applicable form of Election to Settle Early on the reverse of the
Certificate evidencing the related Securities, (i) transfer to the Holder the
Preferred Securities, the Debentures, the Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio or Treasury Securities, as the case may be, forming a part of such
Securities, and (ii) deliver to the Holder a certificate or certificates for the
full number of shares of Common Stock issuable upon such Early Settlement,
together with payment in lieu of any fraction of a share, as provided in Section
5.10.

          (e)  In the event that Early Settlement is effected with respect to
Purchase Contracts underlying less than all the Securities evidenced by a
Certificate, upon such Early Settlement the Company shall execute and the Agent
shall authenticate, countersign and deliver to the Holder thereof, at the
expense of the Company, a Certificate evidencing the Securities as to which
Early Settlement was not effected.

Section 5.10.  No Fractional Shares.

          No fractional shares or scrip representing fractional shares of Common
Stock shall be issued or delivered upon settlement on the Purchase Contract
Settlement Date or upon Early Settlement of any Purchase Contracts. If
Certificates evidencing more than one Purchase Contract shall be surrendered for
settlement at one time by the same Holder, the number of full shares of Common
Stock which shall be delivered upon settlement shall be computed on the basis of
the aggregate number of Purchase Contracts evidenced by the Certificates so
surrendered. Instead of any fractional share of Common Stock which would
otherwise be deliverable upon settlement of any Purchase Contracts on the
Purchase Contract Settlement Date or upon Early Settlement, the Company, through
the Agent, shall make a cash payment in respect of such fractional interest in
an amount equal to the value of such fractional shares times the Applicable
Market Value. The Company shall provide the Agent from time to time with
sufficient funds to permit the Agent to make all cash payments required by this
Section 5.10 in a timely manner.

Section 5.11.  Charges and Taxes.

          The Company will pay all stock transfer and similar taxes attributable
to the initial issuance and delivery of the shares of Common Stock pursuant to
the Purchase Contracts; provided, however, that the Company shall not be
required to pay any such tax or taxes which may be payable in respect of any
exchange of or substitution for a Certificate evidencing a Security or any
issuance of a share of Common Stock in a name other than that of the registered
Holder of a Certificate surrendered in respect of the Securities evidenced
thereby, other than in the name of the Agent, as custodian for such Holder, and
the Company shall not be required to issue or deliver such share certificates or
Certificates unless or until the Person or Persons requesting the transfer or
issuance thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.


                                   ARTICLE VI

                                    Remedies

Section 6.1.   Unconditional Right of Holders to Receive Contract Adjustment
               Payments and to Purchase Common Stock.

          In the event that Contract Adjustment Payments shall constitute a
component of Corporate PIES or Treasury PIES, the Holder of any Corporate PIES
or Treasury PIES shall have the right, which is absolute and unconditional
(subject to the payment by a holder of Contract Adjustment Payments pursuant to
Section 5.9(a)), to receive payment of each installment of the Contract
Adjustment Payments with respect to the Purchase Contract constituting a part of
such Security on the respective Payment Date for such Security and to purchase
Common Stock pursuant to such Purchase Contract and, in each such case, to
institute suit for the enforcement of any such payment and right to purchase
Common Stock, and such rights shall not be impaired without the consent of such
Holder.

Section 6.2.   Restoration of Rights and Remedies.

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

Section 6.3.   Rights and Remedies Cumulative.

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Certificates in the last
paragraph of Section 3.10, no right or remedy herein conferred upon or reserved
to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in

                                      -46-


<PAGE>   52



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 6.4.   Delay or Omission Not Waiver.

          No delay or omission of any Holder to exercise any right or remedy
upon a default shall impair any such right or remedy or constitute a waiver of
any such right. Every right and remedy given by this Article or by law to the
Holders may be exercised from time to time, and as often as may be deemed
expedient, by such Holders.

Section 6.5.   Undertaking for Costs.

          All parties to this Agreement agree, and each Holder of Corporate PIES
or Treasury PIES, by its acceptance of such Corporate PIES or Treasury PIES
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 Agreement, or in
any suit against the Agent for any action taken, suffered or omitted by it as
Agent, 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; provided that the provisions of
this Section shall not apply to any suit instituted by the Company, to any suit
instituted by the Agent, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% of the Outstanding Securities,
or to any suit instituted by any Holder for the enforcement of distributions on
any Preferred Securities or Contract Adjustment Payments, if any, on any
Purchase Contract on or after the respective Payment Date therefor in respect of
any Security held by such Holder, or for enforcement of the right to purchase
shares of Common Stock under the Purchase Contracts constituting part of any
Security held by such Holder.

Section 6.6.   Waiver of Stay or Extension Laws.

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

          of this Agreement or the Pledge Agreement, as applicable.

          (b)  No provision of this Agreement or the Pledge Agreement shall be
construed to relieve the Agent from liability for its own negligent action, its

               (1) this Subsection shall not be construed to limit the effect of
          Subsection (a) of this Section;

               (2) the Agent shall not be liable for any error of judgment made

          hereunder, or in the exercise of any of its rights or powers, if
          adequate indemnity is not provided to it.

          (c)  Whether or not therein expressly so provided, every provision of
this Agreement and the Pledge Agreement relating to the conduct or affecting the
liability of or affording protection to the Agent shall be subject to the
provisions of this Section.

          (d)  The Agent is authorized to execute and deliver the Pledge
Agreement in its capacity as Agent.

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 exercise corporate trust powers, having (or being a member of a bank
holding company having) a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by Federal or State authority and having a
Corporate Trust Office in the Borough of Manhattan, The City of New York, if
there be such a corporation in the Borough of Manhattan, The City of New York,
qualified and eligible under this Article and willing to act on reasonable
terms. 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 Agent shall cease to be eligible in accordance with the provisions
of this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

Section 7.9.   Resignation and Removal; Appointment of Successor.

          (a)  No resignation or removal of the Agent and no appointment of a

applicable requirements of Section 7.10.

          (b)  The Agent may resign at any time by giving written notice thereof
to the Company 60 days prior to the effective date of such resignation. If the

of resignation, the resigning Agent may petition any court of competent
jurisdiction for the appointment of a successor Agent.

          (c)  The Agent may be removed at any time by Act of the Holders of a
majority in number of the Outstanding Securities delivered to the Agent and the
Company.

          (d)  If at any time

               (1) the Agent fails to comply with Section 310(b) of the TIA, as
          if the Agent were an indenture trustee under an indenture qualified
          under the TIA, after written request therefor by the Company or by any
          Holder who has been a bona fide Holder of a Security for at least six
          months, or

               (2) the Agent shall cease to be eligible under Section 7.8 and

          by any such Holder, or

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


                                      -51-

then, in any such case, (i) the Company by a Board Resolution may remove the
Agent, or (ii) any Holder who has been a bona fide Holder of a Security for at
least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Agent and
the appointment of a successor Agent.

          (e)  If the Agent shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Agent for any cause, the

shall become vested with all the rights, powers, agencies and duties of the
retiring Agent; but, on the request of the Company or the successor Agent, such
retiring Agent shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Agent all the rights, powers and
trusts of the retiring Agent and shall duly assign, transfer and deliver to such
successor Agent all property and money held by such retiring Agent hereunder.

such Securities.

Section 7.12.  Preservation of Information; Communications to Holders.

          (a)  The Agent shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders received by the Agent in its
capacity as Registrar.

          (b)  If three or more Holders (herein referred to as "applicants")
apply in writing to the Agent, and furnish to the Agent reasonable proof that
each such applicant has owned a Security for a period of at least six months
preceding the date of such application, and such application states that the
applicants desire to communicate with other Holders with respect to their rights
under this Agreement or under the Securities and is accompanied by a copy of the
form of proxy or other communication which such applicants propose to transmit,
then the Agent shall mail to all the Holders copies of the form of proxy or

mailing.

          Except to the extent otherwise expressly provided in this Agreement,
the Agent assumes no obligations and shall not be subject to any liability under
this Agreement, the Pledge Agreement or any Purchase Contract in respect of the
obligations of the Holder of any Security thereunder. The Company agrees, and
each Holder of a Certificate, by his acceptance thereof, shall be deemed to have
agreed, that the Agent's execution of the Certificates on behalf of the Holders
shall be solely as agent and attorney-in-fact for the Holders, and that the
Agent shall have no obligation to perform such Purchase Contracts on behalf of
the Holders, except to the extent expressly provided in Article Five hereof.
Anything in this Agreement to the contrary notwithstanding, in no event shall
the Agent or its officers, employees or agents be liable under this Agreement to
any third party for indirect, special, punitive, or consequential loss or damage
of any kind whatsoever, including lost profits, whether or not the likelihood of
such loss or damage was known to the Agent, incurred without any act or deed
that is found to be attributable to gross negligence or willful misconduct on
the part of the Agent.

(ii) the issuance, delivery, holding, transfer, redemption or exercise of rights
under the Securities. Such compliance shall include, without limitation, the
preparation and timely filing of required returns and the timely payment of all
amounts required to be withheld to the appropriate taxing authority or its
designated agent.

any written direction received from the Company with respect to the execution or

in accordance with the provisions of Section 7.1(a)(2) hereof.

          (c)  The Agent shall maintain all appropriate records documenting
compliance with such requirements, and shall make such records available, on

Agent's own rights, duties or immunities under this Agreement or otherwise.

Section 8.4.   Effect of Supplemental Agreements.

          Upon the execution of any supplemental agreement under this Article,
this Agreement shall be modified in accordance therewith, and such supplemental

          The Company covenants that it will not merge or consolidate with any
other Person or sell, assign, transfer, lease or convey all or substantially all
of its properties and assets to any Person or group of affiliated Persons in one
transaction or a series of related transactions, unless (i) either the Company

United States of America or a State thereof or the District of Columbia and such
corporation shall expressly assume all the obligations of the Company under the
Purchase Contracts, this Agreement and the Pledge Agreement by one or more
supplemental agreements in form reasonably satisfactory to the Agent and the

lease or conveyance and upon any such assumption by a successor corporation in

substituted for the Company with the same effect as if it had been named herein
as the Company. Such successor corporation thereupon may cause to be signed, and
may issue either in its own name or in the name of NIPSCO Industries, Inc., any
or all of the Certificates evidencing Securities issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Agent; and, upon the order of such successor corporation, instead of the
Company, and subject to all the terms, conditions and limitations in this
Agreement prescribed, the Agent shall authenticate and execute on behalf of the
Holders and deliver any Certificates which previously shall have been signed and
delivered by the officers of the Company to the Agent for authentication and
execution, and any Certificate evidencing Securities which such successor
corporation thereafter shall cause to be signed and delivered to the Agent for
that purpose. All the Certificates issued shall in all respects have the same
legal rank and benefit under this Agreement as the Certificates theretofore or
thereafter issued in accordance with the terms of this Agreement as though all
of such Certificates had been issued at the date of the execution hereof.

          In case of any such consolidation, merger, sale, assignment, transfer,
lease or conveyance such change in phraseology and form (but not in substance)
may be made in the Certificates evidencing Securities thereafter to be issued as
may be appropriate.

Section 9.3.   Opinion of Counsel Given to Agent.

          The Agent, subject to Sections 7.1 and 7.3, shall receive an Opinion
of Counsel as conclusive evidence that any such consolidation, merger, sale,

with the provisions of this Article and that all conditions precedent to the
consummation of any such consolidation, merger, sale, assignment, transfer,
lease or conveyance have been met.

arrears on February 19, May 19, August 19 and November 19 of each year,
commencing May 19, 1999 (a "Payment Date"), shall, subject to receipt thereof by
the Agent from the Securities Intermediary, be paid to the Person in whose name
this Corporate PIES Certificate (or a Predecessor Corporate PIES Certificate) is
registered at the close of business on the Record Date for such Payment Date.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Corporate PIES Certificate to purchase, and the Company to sell, on February 19,
2003 (the "Purchase Contract Settlement Date"), at a price equal to $50 (the
"Stated Amount"), a number of Common Shares,


                                       A-2

without par value ("Common Stock"), of the Company, equal to the Settlement
Rate, unless on or prior to the Purchase Contract Settlement Date there shall
have occurred a Termination Event or an Early Settlement with respect to the
Corporate PIES of which such Purchase Contract is a part, all as provided in the
Purchase Contract Agreement and more fully described on the reverse hereof. The
purchase price (the "Purchase Price") for the shares of Common Stock purchased
pursuant to each Purchase Contract evidenced hereby, if not paid earlier, shall
be paid on the Purchase Contract Settlement Date by separate cash or by
application of payment received in respect of the liquidation amount with
respect to any Pledged Preferred Securities pursuant to the Remarketing or the
appropriate Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, as the case may be, pledged
to secure the obligations under such Purchase Contract of the Holder of the
Corporate PIES of which such Purchase Contract is a part.

         The Company shall pay, on each Payment Date, in respect of each
Purchase Contract forming part of a Corporate PIES evidenced hereby an amount
(the "Contract Adjustment Payments") equal to (a) if a Reset Transaction has not
occurred, 1.85% per annum of the Stated Amount or (b) following the occurrence
of a Reset Transaction, the Adjusted Contract Adjustment Payment Rate related to
such Reset Transaction until any such succeeding Reset Transaction shall occur
(computed on the basis of (i) for any full quarterly period, a 360-day year of
twelve 30-day months and (ii) for any period shorter than a full quarterly
period, a 30-day month and for periods less than a month, the actual number of
days elapsed per 30-day period). Such Contract Adjustment Payments shall be
payable to the Person in whose name this Corporate PIES Certificate (or a
Predecessor Corporate PIES Certificate) is registered at the close of business
on the Record Date for such Payment Date.

         Distributions on the Preferred Securities or the appropriate Applicable
Ownership Interest (as specified in clause (B) of the definition of such term)
of the Treasury Portfolio, as the case may be, and Contract Adjustment Payments
will be payable at the office of the Agent in The City of New York or, at the
option of the Company, by check mailed to the address of the Person entitled
thereto as such address appears on the Corporate PIES Register.

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

         Unless the certificate of authentication hereon has been executed by
the Agent by manual signature, this Corporate PIES Certificate shall not be
entitled to any benefit under the Pledge Agreement or the Purchase Contract
Agreement or be valid or obligatory for any purpose.

                 (FORM OF REVERSE OF CORPORATE PIES CERTIFICATE)


         Each Purchase Contract evidenced hereby is governed by a Purchase
Contract Agreement, dated as of February 16, 1999 (as may be supplemented from
time to time, the "Purchase Contract Agreement"), between the Company and The
Chase Manhattan Bank, as Purchase Contract Agent (including its successors
hereunder, the "Agent"), to which Purchase Contract Agreement and supplemental
agreements thereto reference is hereby made for a description of the respective
rights, limitations of rights, obligations, duties and immunities thereunder of
the Agent, the Company, and the Holders and of the terms upon which the
Corporate PIES Certificates are, and are to be, executed and delivered.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Corporate PIES Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a price equal to the Stated Amount (the "Purchase
Price"), a number of shares of Common Stock of the Company equal to the
Settlement Rate, unless, on or prior to the Purchase Contract Settlement Date,
there shall have occurred a Termination Event with respect to the Security of
which such Purchase Contract is a part or an Early Settlement shall have
occurred. The "Settlement Rate" is equal to (a) if the Applicable Market Value
(as defined below) is equal to or greater than $31.0500 (the "Threshold
Appreciation Price"), 1.6103 shares of Common Stock per Purchase Contract, (b)
if the Applicable Market Value is less than the Threshold Appreciation Price but
is greater than $26.3125, the number of shares of Common Stock per Purchase
Contract equal to the Stated Amount divided by the Applicable Market Value and
(c) if the Applicable Market Amount is less than or equal to $26.3125, 1.9002
shares of Common Stock per Purchase Contract, in each case subject to adjustment
as provided in the Purchase Contract Agreement. No fractional shares of Common
Stock will be issued upon settlement of Purchase Contracts, as provided in the
Purchase Contract Agreement.

         Each Purchase Contract evidenced hereby, which is settled either
through Early Settlement or Cash Settlement, shall obligate the Holder of the
related Corporate PIES to purchase at the Purchase Price, and the Company to
sell, a number of newly issued shares of Common Stock equal to the Early
Settlement Rate or the Settlement Rate, as applicable.

         The "Applicable Market Value" means the average of the Closing Price
per share of Common Stock on each of the 20 Trading Days ending on the third
Trading Day immediately preceding the Purchase Contract Settlement Date or any
applicable Early Settlement Date. The "Closing Price" of the Common Stock on any
date of determination means (i) the closing sale price (or, if no closing price
is reported, the last reported sale price) of the Common Stock on the New York
Stock Exchange (the "NYSE") on such date, (ii) if the Common Stock is not listed
for trading on the NYSE on any such date, the closing sale price as reported in
the composite transactions for the principal United States securities exchange
on which the Common Stock is so listed, (iii) if the Common Stock is not so
listed on a United States national or regional securities exchange, the closing
sale price as reported by The Nasdaq Stock Market, (iv) if the Common Stock is
not so reported, the last quoted bid price for the Common Stock in the
over-the-counter market as reported by the National Quotation Bureau or similar
organization, or (v) if such bid price is not available, the average of the
mid-point of the last bid and ask prices of



                                      A-5
<PAGE>   71
the Common Stock on such date from at least three nationally recognized
independent investment banking firms retained for this purpose by the Company. A
"Trading Day" means a day on which the Common Stock (A) is not suspended from
trading on any national or regional securities exchange or association or
over-the-counter market at the close of business and (B) has traded at least
once on the national or regional securities exchange or association or
over-the-counter market that is the primary market for the trading of the Common
Stock.

         In accordance with the terms of the Purchase Contract Agreement, the
Holder of this Corporate PIES Certificate may pay the Purchase Price for the
shares of Common Stock purchased pursuant to each Purchase Contract evidenced
hereby by effecting a Cash Settlement or an Early Settlement or from the
proceeds of the Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio or a remarketing of the
related Pledged Preferred Securities. A Holder of Corporate PIES who does not
effect, on or prior to 11:00 a.m. New York City time on the fifth Business Day
immediately preceding the Purchase Contract Settlement Date (or in the event a
Tax Event Redemption has occurred, the Business Day prior to the Purchase
Contract Settlement Date), an effective Cash Settlement or an Early Settlement,
shall pay the Purchase Price for the shares of Common Stock to be issued under
the related Purchase Contract from the proceeds of the Applicable Ownership
Interest (as specified in clause (A) of the definition of such term) of the
Treasury Portfolio or the sale of the related Pledged Preferred Securities held
by the Collateral Agent. Such sale will be made by the Remarketing Agent
pursuant to the terms of the Remarketing Agreement on the third Business Day
prior to the Purchase Contract Settlement Date. If, as provided in the Purchase
Contract Agreement, upon the occurrence of a Failed Remarketing the Collateral
Agent, for the benefit of the Company, exercises its rights as a secured
creditor with respect to the Pledged Preferred Securities related to this
Corporate PIES certificate, any accrued and unpaid distributions on such Pledged
Preferred Securities will become payable by the Company to the holder of this
Corporate PIES Certificate in the manner provided for in the Purchase Contract
Agreement.

         The Company shall not be obligated to issue any shares of Common Stock
in respect of a Purchase Contract or deliver any certificates therefor to the
Holder unless it shall have received payment of the aggregate purchase price for
the shares of Common Stock to be purchased thereunder in the manner herein set
forth.

         Each Purchase Contract evidenced hereby and all obligations and rights
of the Company and the Holder thereunder shall terminate if a Termination Event
shall occur. Upon the occurrence of a Termination Event, the Company shall give
written notice to the Agent and to the Holders, at their addresses as they
appear in the Corporate PIES Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Pledged Preferred
Security or the appropriate Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) of the Treasury Portfolio forming a
part of each Corporate PIES from the Pledge. A Corporate PIES shall thereafter
represent the right to receive the Preferred Security or the appropriate
Applicable Ownership Interest of the Treasury Portfolio forming a part of such
Corporate PIES in accordance with the terms of the Purchase Contract Agreement
and the Pledge Agreement.



                                      A-6
<PAGE>   72
         Under the terms of the Pledge Agreement, the Agent will be entitled to
exercise the voting and any other consensual rights pertaining to the Pledged
Preferred Securities. Upon receipt of notice of any meeting at which holders of
Preferred Securities are entitled to vote or upon the solicitation of consents,
waivers or proxies of holders of Preferred Securities, the Agent shall, as soon
as practicable thereafter, mail to the Corporate PIES Holders a notice (a)
containing such information as is contained in the notice or solicitation, (b)
stating that each Corporate PIES Holder on the record date set by the Agent
therefor (which, to the extent possible, shall be the same date as the record
date for determining the holders of Preferred Securities entitled to vote) shall
be entitled to instruct the Agent as to the exercise of the voting rights
pertaining to the Preferred Securities constituting a part of such Holder's
Corporate PIES and (c) stating the manner in which such instructions may be
given. Upon the written request of the Corporate PIES Holders on such record
date, the Agent shall endeavor insofar as practicable to vote or cause to be
voted, in accordance with the instructions set forth in such requests, the
maximum number of Preferred Securities as to which any particular voting
instructions are received. In the absence of specific instructions from the
Holder of a Corporate PIES, the Agent shall abstain from voting the Preferred
Security evidenced by such Corporate PIES.

         Upon the liquidation of the Trust, a principal amount of the Debentures
constituting the assets of the Trust and underlying the Preferred Securities
equal to the aggregate liquidation amount of the Pledged Preferred Securities
shall be delivered to the Securities Intermediary in exchange for the Pledged
Preferred Securities. Thereafter, the Debentures shall be held by the Securities
Intermediary to secure the obligations of each Holder of Corporate PIES to
purchase shares of Common Stock under the Purchase Contracts constituting a part
of such Corporate PIES. Following the liquidation of the Trust, the Holders and
the Collateral Agent shall have such security interests, rights and obligations
with respect to the Debentures as the Holders and the Collateral Agent had in
respect of the Pledged Preferred Securities, any reference herein to the
Preferred Securities shall be deemed to be a reference to the Debentures and any
reference herein to the liquidation amount of the Preferred Securities shall be
deemed to be a reference to the principal amount of the Debentures.

         Upon the occurrence of a Tax Event Redemption prior to the Purchase
Contract Settlement Date, the Redemption Price payable on the Tax Event
Redemption Date with respect to the Applicable Principal Amount of Debentures
shall be delivered to the Securities Intermediary in exchange for the Pledged
Preferred Securities. Thereafter, pursuant to the terms of the Pledge Agreement,
the Securities Intermediary will apply an amount equal to the Redemption Amount
of such Redemption Price to purchase, the Treasury Portfolio and promptly (a)
transfer the Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio to the Collateral Account to
secure the obligations of each Holder of Corporate PIES to purchase shares of
Common Stock under the Purchase Contracts constituting a part of such Corporate
PIES, (b) transfer the Applicable Ownership Interest (as specified in clause (B)
of the definition of such term) of the Treasury Portfolio to the Agent for the
benefit of the Holders of such Corporate PIES and (iii) remit the remaining
portion of such Redemption Price to the Agent for payment to the Holders of such
Corporate PIES.

         Following the occurrence of a Tax Event Redemption prior to the
Purchase Contract Settlement Date, the Holders of Corporate PIES and the
Collateral Agent shall have such security


                                      A-7
<PAGE>   73
interest rights and obligations with respect to the Applicable Ownership
Interest (as specified in clause (A) of the definition of such term) of the
Treasury Portfolio as the Holder of Corporate PIES and the Collateral Agent had
in respect of the Preferred Securities or Debentures, as the case may be,
subject to the Pledge thereof as provided in Articles II, III, IV, V and VI, of
the Pledge Agreement and any reference herein to the Preferred Securities shall
be deemed to be a reference to such Treasury Portfolio.

         The Corporate PIES Certificates are issuable only in registered form
and only in denominations of a single Corporate PIES and any integral multiple
thereof. The transfer of any Corporate PIES Certificate will be registered and
Corporate PIES Certificates may be exchanged as provided in the Purchase
Contract Agreement. The Corporate PIES Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents
permitted by the Purchase Contract Agreement. No service charge shall be
required for any such registration of transfer or exchange, but the Company and
the Agent may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith. A holder who elects to
substitute a Treasury Security for Preferred Securities or the appropriate
Applicable Ownership Interest of the Treasury Portfolio, thereby creating
Treasury PIES, shall be responsible for any fees or expenses payable in
connection therewith. Except as provided in the Purchase Contract Agreement, for
so long as the Purchase Contract underlying a Corporate PIES remains in effect,
such Corporate PIES shall not be separable into its constituent parts, and the
rights and obligations of the Holder of such Corporate PIES in respect of the
Preferred Security or the appropriate Applicable Ownership Interest of the
Treasury Portfolio, as the case may be, and Purchase Contract constituting such
Corporate PIES may be transferred and exchanged only as a Corporate PIES. The
holder of a Corporate PIES may substitute for the Pledged Preferred Securities
or the appropriate Applicable Ownership Interest (as specified in clause (A) of
the definition of such term) of the Treasury Portfolio securing its obligation
under the related Purchase Contract Treasury Securities in an aggregate
principal amount equal to the aggregate liquidation amount of the Pledged
Preferred Securities or the appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio in accordance with the terms of the Purchase Contract Agreement and
the Pledge Agreement. From and after such Collateral Substitution, the Security
for which such Pledged Treasury Securities secures the holder's obligation under
the Purchase Contract shall be referred to as a "Treasury PIES." A Holder may
make such Collateral Substitution only in integral multiples of 20 Corporate
PIES for 20 Treasury PIES; provided, however, that if a Tax Event Redemption has
occurred and the Treasury Portfolio has become a component of the Corporate
PIES, a Holder may make such Collateral Substitution only in integral multiples
of 160,000 Corporate PIES for 160,000 Treasury PIES. Such Collateral
Substitution may cause the equivalent aggregate principal amount of this
Certificate to be increased or decreased; provided, however, this Corporate PIES
Certificate shall not represent more than ____ Corporate PIES. All such
adjustments to the equivalent aggregate principal amount of this Corporate PIES
Certificate shall be duly recorded by placing an appropriate notation on the
Schedule attached hereto.

         A Holder of Treasury PIES may recreate Corporate PIES by delivering to
the Securities Intermediary Preferred Securities or the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio, with an aggregate liquidation amount, in the case of
such Preferred Securities, or with the appropriate Applicable



                                      A-8
<PAGE>   74

Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio, in the case of such appropriate Applicable Ownership
Interest (as specified in clause (A) of the definition of such term) of the
Treasury Portfolio, equal to the aggregate principal amount of the Pledged
Treasury Securities in exchange for the release of such Pledged Treasury
Securities in accordance with the terms of the Purchase Contract Agreement and
the Pledge Agreement.

         The Company shall pay, on each Payment Date, the Contract Adjustment
Payments payable in respect of each Purchase Contract to the Person in whose
name the Corporate PIES Certificate evidencing such Purchase Contract is
registered at the close of business on the Record Date for such Payment Date.
Contract Adjustment Payments will be payable at the office of the Agent in The
City of New York or, at the option of the Company, by check mailed to the
address of the Person entitled thereto at such address as it appears on the
Corporate PIES Register.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights of the
Holders to receive and the obligation of the Company to pay any Contract
Adjustment Payments, shall immediately and automatically terminate, without the
necessity of any notice or action by any Holder, the Agent or the Company, if,
on or prior to the Purchase Contract Settlement Date, a Termination Event shall
have occurred. Upon the occurrence of a Termination Event, the Company shall
promptly but in no event later than two Business Days thereafter give written
notice to the Agent, the Collateral Agent and the Holders, at their addresses as
they appear in the Corporate PIES Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Preferred Securities
or the appropriate Applicable Ownership Interest (as specified in clause (A) of
the definition of such term) of the Treasury Portfolio, as the case may be, from
the Pledge in accordance with the provisions of the Pledge Agreement.

         Subject to and upon compliance with the provisions of the Purchase
Contract Agreement, at the option of the Holder thereof, Purchase Contracts
underlying Securities may be settled early ("Early Settlement") as provided in
the Purchase Contract Agreement; provided, however, that if a Tax Event
Redemption has occurred and the Treasury Portfolio has become a component of the
Corporate PIES, Holders may settle early Corporate PIES only in integral
multiples of 160,000 Corporate PIES. In order to exercise the right to effect
Early Settlement with respect to any Purchase Contracts evidenced by this
Corporate PIES Certificate, the Holder of this Corporate PIES Certificate shall
deliver this Corporate PIES Certificate to the Agent at the Corporate Trust
Office duly endorsed for transfer to the Company or in blank with the form of
Election to Settle Early set forth below duly completed and accompanied by
payment in the form of immediately available funds payable to the order of the
Company in an amount (the "Early Settlement Amount") equal to (i) the product of
(A) the Stated Amount times (B) the number of Purchase Contracts with respect to
which the Holder has elected to effect Early Settlement, plus (ii) if such
delivery is made with respect to any Purchase Contracts during the period from
the close of business on any Record Date for any Payment Date to the opening of
business on such Payment Date, an amount equal to the Contract Adjustment
Payments payable on such Payment Date with respect to such Purchase Contracts.
Upon Early Settlement of Purchase Contracts by a Holder of the related
Securities, the Pledged Preferred Securities or the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio


                                      A-9
<PAGE>   75

underlying such Securities shall be released from the Pledge as provided in the
Pledge Agreement and the Holder shall be entitled to receive a number of shares
of Common Stock on account of each Purchase Contract forming part of a Corporate
PIES as to which Early Settlement is effected equal to the Early Settlement
Rate. The Early Settlement Rate shall initially be equal to 1.6103 shares of
Common Stock and shall be adjusted in the same manner and at the same time as
the Settlement Rate is adjusted as provided in the Purchase Contract Agreement.

         Upon registration of transfer of this Corporate PIES Certificate, the
transferee shall be bound (without the necessity of any other action on the part
of such transferee, except as may be required by the Agent pursuant to the
Purchase Contract Agreement), under the terms of the Purchase Contract Agreement
and the Purchase Contracts evidenced hereby and the transferor shall be released
from the obligations under the Purchase Contracts evidenced by this Corporate
PIES Certificate. The Company covenants and agrees, and the Holder, by its
acceptance hereof, likewise covenants and agrees, to be bound by the provisions
of this paragraph.

         The Holder of this Corporate PIES Certificate, by its acceptance
hereof, authorizes the Agent to enter into and perform the related Purchase
Contracts forming part of the Corporate PIES evidenced hereby on its behalf as
its attorney-in-fact, expressly withholds any consent to the assumption (i.e.,
affirmance) of the Purchase Contracts by the Company or its trustee in the event
that the Company becomes the subject of a case under the Bankruptcy Code, agrees
to be bound by the terms and provisions thereof, covenants and agrees to perform
his obligations under such Purchase Contracts, consents to the provisions of the
Purchase Contract Agreement, authorizes the Agent to enter into and perform the
Purchase Contract Agreement and the Pledge Agreement on its behalf as its
attorney-in-fact, and consents to the Pledge of the Preferred Securities or the
appropriate Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, as the case may be,
underlying this Corporate PIES Certificate pursuant to the Pledge Agreement. The
Holder further covenants and agrees that, to the extent and in the manner
provided in the Purchase Contract Agreement and the Pledge Agreement, but
subject to the terms thereof, payments in respect to the aggregate liquidation
amount of the Pledged Preferred Securities or the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio, on the Purchase Contract Settlement Date shall be
paid by the Collateral Agent to the Company in satisfaction of such Holder's
obligations under such Purchase Contract and such Holder shall acquire no right,
title or interest in such payments.

         Subject to certain exceptions, the provisions of the Purchase Contract
Agreement may be amended with the consent of the Holders of a majority of the
Purchase Contracts.

         The Purchase Contracts shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York.

         The Company, the Agent and its Affiliates and any agent of the Company
or the Agent may treat the Person in whose name this Corporate PIES Certificate
is registered as the owner of the Corporate PIES evidenced hereby for the
purpose of receiving payments of distributions payable quarterly on the
Preferred Securities, receiving payments of Contract Adjustment


                                      A-10
<PAGE>   76
Payments, performance of the Purchase Contracts and for all other purposes
whatsoever, whether or not any payments in respect thereof be overdue and
notwithstanding any notice to the contrary, and neither the Company, the Agent
nor any such agent shall be affected by notice to the contrary.

         The Purchase Contracts shall not, prior to the settlement thereof,
entitle the Holder to any of the rights of a holder of shares of Common Stock.

         A copy of the Purchase Contract Agreement is available for inspection
at the offices of the Agent.

                                  TREASURY PIES

         This Treasury PIES Certificate certifies that Cede & Co. is the
registered Holder of the number of Treasury PIES set forth above. Each Treasury
PIES consists of (i) a 1/20 undivided beneficial ownership interest of a
Treasury Security having a principal amount at maturity equal to $1,000, subject
to the Pledge of such Treasury Security by such Holder pursuant to the Pledge
Agreement, and (ii) the rights and obligations of the Holder under one Purchase
Contract with NIPSCO Industries, Inc., an Indiana corporation (the "Company").
All capitalized terms used herein which are defined in the Purchase Contract
Agreement (as defined on the reverse hereof) have the meaning set forth therein.


<PAGE>   84



         Pursuant to the Pledge Agreement, the Treasury Securities constituting
part of each Treasury PIES evidenced hereby have been pledged to the Collateral
Agent, for the benefit of the Company, to secure the obligations of the Holder
under the Purchase Contract comprising a portion of such Treasury PIES.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Treasury PIES Certificate to purchase, and the Company, to sell, on February 19,
2003 (the "Purchase Contract Settlement Date"), at a price equal to $50 (the
"Stated Amount"), a number of Common Shares, without par value ("Common Stock"),
of the Company equal to the Settlement Rate, unless on or prior to the Purchase
Contract Settlement Date there shall have occurred a Termination Event or an
Early Settlement with respect to the Treasury PIES of which such Purchase
Contract is a part, all as provided in the Purchase Contract Agreement and more
fully described on the reverse hereof. The purchase price for the shares of
Common Stock purchased pursuant to each Purchase Contract evidenced hereby, if
not paid earlier, shall be paid on the Purchase Contract Settlement Date by
application of the Proceeds from the Treasury Securities pledged to secure the
obligations under such Purchase Contract in accordance with the terms of the
Pledge Agreement.

         The Company shall pay on each Payment Date in respect of each Purchase
Contract evidenced hereby an amount (the "Contract Adjustment Payments") equal
to (a) if a Reset Transaction has not occurred, 1.85% per annum of the Stated
Amount or (b) following the occurrence of a Reset Transaction, the Adjusted
Contract Adjustment Payment Rate related to such Reset Transaction until any
such succeeding Reset Transaction shall occur (computed on the basis of (i) for
any full quarterly period, a 360-day year of twelve 30-day months and (ii) for
any period shorter than a full quarterly period, a 30-day month and for periods
less than a month, the actual number of days elapsed per 30-day period), as the
case may be. Such Contract Adjustment Payments shall be payable to the Person in
whose name this Treasury PIES Certificate (or a Predecessor Treasury PIES
Certificate) is registered at the close of business on the Record Date for such
Payment Date.

         Contract Adjustment Payments will be payable at the office of the Agent
in The City of New York or, at the option of the Company, by check mailed to the
address of the Person entitled thereto as such address appears on the Treasury
PIES Register.

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

         Unless the certificate of authentication hereon has been executed by
the Agent by manual signature, this Treasury PIES Certificate shall not be
entitled to any benefit under the Pledge Agreement or the Purchase Contract
Agreement or be valid or obligatory for any purpose.

                     (REVERSE OF TREASURY PIES CERTIFICATE)

         Each Purchase Contract evidenced hereby is governed by a Purchase
Contract Agreement, dated as of February 16, 1999 (as may be supplemented from
time to time, the "Purchase Contract Agreement") between the Company and The
Chase Manhattan Bank, as Purchase Contract Agent (including its successors
thereunder, herein called the "Agent"), to which the Purchase Contract Agreement
and supplemental agreements thereto reference is hereby made for a description
of the respective rights, limitations of rights, obligations, duties and
immunities thereunder of the Agent, the Company and the Holders and of the terms
upon which the Treasury PIES Certificates are, and are to be, executed and
delivered.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Treasury PIES Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a price equal to the Stated Amount (the "Purchase
Price") a number of shares of Common Stock of the Company equal to the
Settlement Rate, unless on or prior to the Purchase Contract Settlement Date,
there shall have occurred a Termination Event with respect to the Security of
which such Purchase Contract is a part or an Early Settlement shall have
occurred. The "Settlement Rate" is equal to (a) if the Applicable Market Value
(as defined below) is equal to or greater than $31.0500 (the "Threshold
Appreciation Price"), 1.6103 shares of Common Stock per Purchase Contract, (b)
if the Applicable Market Value is less than the Threshold Appreciation Price but
is greater than $26.3125, the number of shares of Common Stock per Purchase
Contract equal to the Stated Amount divided by the Applicable Market Value and
(c) if the Applicable Market Amount is less than or equal to $26.3125, then
1.9002 shares of Common Stock per Purchase Contract, in each case subject to
adjustment as provided in the Purchase Contract Agreement. No fractional shares
of Common Stock will be issued upon settlement of Purchase Contracts, as
provided in the Purchase Contract Agreement.

         Each Purchase Contract evidenced hereby, which is settled either
through Early Settlement or Cash Settlement, shall obligate the Holder of the
related Treasury PIES to purchase at the Purchase Price for cash, and the
Company to sell, a number of newly issued shares of Common Stock equal to the
Early Settlement Rate or the Settlement Rate, as applicable.

         The "Applicable Market Value" means the average of the Closing Prices
per share of Common Stock on each of the 20 Trading Days ending on the third
Trading Day immediately preceding the Purchase Contract Settlement Date or any
applicable Early Settlement Date. The "Closing Price" of the Common Stock on any
date of determination means the (i) closing sale price (or, if no closing price
is reported, the last reported sale price) of the Common Stock on the New York
Stock Exchange (the "NYSE") on such date, (ii) if the Common Stock is not listed
for trading on the NYSE on any such date, the closing sale price as reported in
the composite transactions for the principal United States securities exchange
on which the Common Stock is so listed, (iii) if the Common Stock is not so
listed on a United States national or regional securities exchange, the closing
sale price as reported by The Nasdaq Stock Market, (iv) if the Common Stock is
not so reported, the last quoted bid price for the Common Stock in the
over-the-counter market as reported by the National Quotation Bureau or similar
organization, or (v) if such bid price is not available, the average of the
mid-point of the last bid and ask prices of the Common Stock on such date from
at least three nationally recognized independent investment banking firms
retained for this purpose by the Company. A "Trading Day" means a



                                       B-5

<PAGE>   88



day on which the Common Stock (A) is not suspended from trading on any national
or regional securities exchange or association or over-the-counter market at the
close of business and (B) has traded at least once on the national or regional
securities exchange or association or over-the-counter market that is the
primary market for the trading of the Common Stock.

         In accordance with the terms of the Purchase Contract Agreement, the
Holder of this Treasury PIES shall pay the Purchase Price for the shares of
Common Stock purchased pursuant to each Purchase Contract evidenced hereby
either by effecting a Cash Settlement or an Early Settlement of each such
Purchase Contract or by applying a principal amount of the Pledged Treasury
Securities underlying such Holder's Treasury PIES equal to the Stated Amount of
such Purchase Contract to the purchase of the Common Stock. A Holder of Treasury
PIES who does not effect, on or prior to 11:00 a.m. New York City time on the
Business Day immediately preceding the Purchase Contract Settlement Date, an
effective Cash Settlement or an Early Settlement, shall pay the Purchase Price
for the shares of Common Stock to be issued under the related Purchase Contract
from the proceeds of the Pledged Treasury Securities.

         The Company shall not be obligated to issue any shares of Common Stock
in respect of a Purchase Contract or deliver any certificates therefor to the
Holder unless it shall have received payment of the aggregate purchase price for
the shares of Common Stock to be purchased thereunder in the manner herein set
forth.

         Each Purchase Contract evidenced hereby and all obligations and rights
of the Company and the Holder thereunder shall terminate if a Termination Event
shall occur. Upon the occurrence of a Termination Event, the Company shall give
written notice to the Agent and to the Holders, at their addresses as they
appear in the Treasury PIES Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Pledged Treasury
Securities (as defined in the Pledge Agreement) forming a part of each Treasury
PIES. A Treasury PIES shall thereafter represent the right to receive the
interest in the Treasury Security forming a part of such Treasury PIES, in
accordance with the terms of the Purchase Contract Agreement and the Pledge
Agreement.

         The Treasury PIES Certificates are issuable only in registered form and
only in denominations of a single Treasury PIES and any integral multiple
thereof. The transfer of any Treasury PIES Certificate will be registered and
Treasury PIES Certificates may be exchanged as provided in the Purchase Contract
Agreement. The Treasury PIES Registrar may require a Holder, among other things,
to furnish appropriate endorsements and transfer documents permitted by the
Purchase Contract Agreement. No service charge shall be required for any such
registration of transfer or exchange, but the Company and the Agent may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. A Holder who elects to substitute Preferred
Securities, Debentures or the appropriate Applicable Ownership Interest of the
Treasury Portfolio, as the case may be, for Treasury Securities, thereby
recreating Corporate PIES, shall be responsible for any fees or expenses
associated therewith. Except as provided in the Purchase Contract Agreement, for
so long as the Purchase Contract underlying a Treasury PIES remains in effect,
such Treasury PIES shall not be separable into its constituent parts, and the
rights and obligations of the Holder of such Treasury PIES in respect of the
Treasury Security and the Purchase Contract constituting such Treasury PIES may
be transferred and exchanged only as a Treasury PIES. A Holder of Treasury PIES
may recreate


                                       B-6

<PAGE>   89
Corporate PIES by delivering to the Collateral Agent Preferred Securities or the
appropriate Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, with a liquidation amount,
in the case of such Preferred Securities, with a principal amount in the case of
such Debentures, or with the appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio, in the case of such appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio, equal to the aggregate principal amount at maturity of the Pledged
Treasury Securities in exchange for the release of such Pledged Treasury
Securities in accordance with the terms of the Purchase Contract Agreement and
the Pledge Agreement. From and after such substitution, the Holder's Security
shall be referred to as an "Corporate PIES." Such substitution may cause the
equivalent aggregate principal amount of this Certificate to be increased or
decreased; provided, however, this Treasury PIES Certificate shall not represent
more than ____ Treasury PIES. All such adjustments to the equivalent aggregate
principal amount of this Treasury PIES Certificate shall be duly recorded by
placing an appropriate notation on the Schedule attached hereto.

         A Holder of a Corporate PIES may recreate a Treasury PIES by delivering
to the Collateral Agent Treasury Securities in an aggregate principal amount
equal to the aggregate liquidation amount of the Pledged Preferred Securities,
the aggregate principal amount at maturity of the Pledged Debentures or the
appropriate Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, as the case may be, in
exchange for the release of such Pledged Preferred Securities, Pledged
Debentures or the appropriate Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) of the Treasury Portfolio, as the
case may be, in accordance with the terms of the Purchase Contract Agreement and
the Pledge Agreement. Any such recreation of a Treasury PIES may be effected
only in multiples of 20 Corporate PIES for 20 Treasury PIES; provided, however,
if a Tax Event Redemption has occurred and the Treasury Portfolio has become a
component of the Corporate PIES, a Holder may recreate Corporate PIES in
integral multiples of 160,000 Corporate PIES for 160,000 Treasury PIES.

         The Company shall pay, on each Payment Date, the Contract Adjustment
Payments payable in respect of each Purchase Contract to the Person in whose
name the Treasury PIES Certificate evidencing such Purchase Contract is
registered at the close of business on the Record Date for such Payment Date.
Contract Adjustment Payments will be payable at the office of the Agent in The
City of New York or, at the option of the Company, by check mailed to the
address of the Person entitled thereto at such address as it appears on the
Treasury PIES Register.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights of the
Holders to receive and the obligation of the Company to pay Contract Adjustment
Payments, shall immediately and automatically terminate, without the necessity
of any notice or action by any Holder, the Agent or the Company, if, on or prior
to the Purchase Contract Settlement Date, a Termination Event shall have
occurred. Upon the occurrence of a Termination Event, the Company shall promptly
but in no event later than two Business Days thereafter give written notice to
the Agent, the Collateral Agent and the Holders, at their addresses as they
appear in the Treasury PIES Register. Upon the occurrence of a Termination
Event, the Collateral Agent shall release the Treasury Securities from the
Pledge in accordance with the provisions of the Pledge Agreement.

<PAGE>   90
         Subject to and upon compliance with the provisions of the Purchase
Contract Agreement, at the option of the Holder thereof, Purchase Contracts
underlying Securities may be settled early ("Early Settlement") as provided in
the Purchase Contract Agreement. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Treasury
PIES the Holder of this Treasury PIES Certificate shall deliver this Treasury
PIES Certificate to the Agent at the Corporate Trust Office duly endorsed for
transfer to the Company or in blank with the form of Election to Settle Early
set forth below duly completed and accompanied by payment in the form of
immediately available funds payable to the order of the Company in an amount
(the "Early Settlement Amount") equal to (i) the product of (A) $50 times (B)
the number of Purchase Contracts with respect to which the Holder has elected to
effect Early Settlement, plus (ii) if such delivery is made with respect to any
Purchase Contracts during the period from the close of business on any Record
Date for any Payment Date to the opening of business on such Payment Date, an
amount equal to the Contract Adjustment Payments payable, if any, on such
Payment Date with respect to such Purchase Contracts. Upon Early Settlement of
Purchase Contracts by a Holder of the related Securities, the Pledged Treasury
Securities underlying such Securities shall be released from the Pledge as
provided in the Pledge Agreement and the Holder shall be entitled to receive a
number of shares of Common Stock on account of each Purchase Contract forming
part of a Treasury PIES as to which Early Settlement is effected equal to 1.6103
shares of Common Stock per Purchase Contract (the "Early Settlement Rate"). The
Early Settlement Rate shall be adjusted in the same manner and at the same time
as the Settlement Rate is adjusted as provided in the Purchase Contract
Agreement.

         Upon registration of transfer of this Treasury PIES Certificate, the
transferee shall be bound (without the necessity of any other action on the part
of such transferee, except as may be required by the Agent pursuant to the
Purchase Contract Agreement), under the terms of the Purchase Contract Agreement
and the Purchase Contracts evidenced hereby and the transferor shall be released
from the obligations under the Purchase Contracts evidenced by this Treasury
PIES Certificate. The Company covenants and agrees, and the Holder, by its
acceptance hereof, likewise covenants and agrees, to be bound by the provisions
of this paragraph.

         The Holder of this Treasury PIES Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Treasury PIES evidenced hereby on its behalf as its
attorney-in-fact, expressly withholds any consent to the assumption (i.e.,
affirmance) of the Purchase Contracts by the Company or its trustee in the event
that the Company becomes the subject of a case under the Bankruptcy Code, agrees
to be bound by the terms and provisions thereof, covenants and agrees to perform
its obligations under such Purchase Contracts, consents to the provisions of the
Purchase Contract Agreement, authorizes the Agent to enter into and perform the
Purchase Contract Agreement and the Pledge Agreement on its behalf as its
attorney-in-fact, and consents to the Pledge of the Treasury Securities
underlying this Treasury PIES Certificate pursuant to the Pledge Agreement. The
Holder further covenants and agrees, that, to the extent and in the manner
provided in the Purchase Contract Agreement and the Pledge Agreement, but
subject to the terms thereof, payments in respect to the aggregate principal
amount of the Pledged Treasury Securities on the Purchase Contract Settlement
Date shall be paid by the Collateral Agent to the Company in satisfaction of
such Holder's obligations under such Purchase Contract and such Holder shall
acquire no right, title or interest in such payments.


                                       B-8

<PAGE>   91
         Subject to certain exceptions, the provisions of the Purchase Contract
Agreement may be amended with the consent of the Holders of a majority of the
Purchase Contracts.

         The Purchase Contracts shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York.

         The Company, the Agent and its Affiliates and any agent of the Company
or the Agent may treat the Person in whose name this Treasury PIES Certificate
is registered as the owner of the Treasury PIES evidenced hereby for the purpose
of receiving payments of interest on the Treasury Securities, receiving payments
of Contract Adjustment Payments, performance of the Purchase Contracts and for
all other purposes whatsoever, whether or not any payments in respect thereof be
overdue and notwithstanding any notice to the contrary, and neither the Company,
the Agent nor any such agent shall be affected by notice to the contrary.

         The Purchase Contracts shall not, prior to the settlement thereof,
entitle the Holder to any of the rights of a holder of shares of Common Stock.

         A copy of the Purchase Contract Agreement is available for inspection
at the offices of the Agent.

shall be deemed to have consented to the disposition of the Pledged Preferred
Securities or Pledged Debentures of such Holder in accordance with paragraph
5.4(a)(iii) of the Purchase Contract Agreement.

                                                                              15


     (c)  If a Holder of a Treasury PIES or Corporate PIES (if a Tax Event
Redemption has occurred) notifies the Purchase Contract Agent as provided in
paragraph 5.4(d)(i) of the Purchase Contract Agreement of its intention to pay
the Purchase Price in cash, but fails to make such payment as required by
paragraph 5.4(d)(ii) of the Purchase Contract Agreement, such Holder shall be
deemed to have elected to pay the Purchase Price in accordance with paragraph
5.4(d)(iii) of the Purchase Contract Agreement.

     (d)  Prior to 3:00 p.m., New York City time, on the fourth Business Day
immediately preceding the Purchase Contract Settlement Date, the Securities
Intermediary shall deliver to the Purchase Contract Agent a notice,
substantially in the form of Exhibit E hereto, stating (i) the amount of cash
that it has received with respect to the Cash Settlement of Corporate PIES and
(ii) the amount of cash that it has received with respect to the Cash Settlement
of Treasury PIES.

     Section 5.6 Early Settlement. Upon written notice to the Collateral Agent
by the Purchase Contract Agent that one or more Holders of Securities have
elected to effect Early Settlement of their respective obligations under the
Purchase Contracts forming a part of such Securities in accordance with the
terms of the Purchase Contracts and the Purchase Contract Agreement (setting
forth the number of such Purchase Contracts as to which such Holders have
elected to effect Early Settlement), and that the Purchase Contract Agent has
received from such Holders, and paid to the Company as confirmed in writing by
the Company, the related Early Settlement Amounts pursuant to the terms of the
Purchase Contracts and the Purchase Contract Agreement and that all conditions
to such Early Settlement have been satisfied, then the Collateral Agent shall
release from the Pledge, (a) Pledged Preferred Securities or the appropriate
Applicable Ownership Interest (as specified in clause (A) of the definition of
such term) of the Treasury Portfolio or Pledged Debentures in the case of a
Holder of Corporate PIES or (b) Pledged Treasury Securities, in the case of a
Holder of Treasury PIES, with a Value equal to the product of (i) the Stated
Amount times (ii) the number of Purchase Contracts as to which such Holders have
elected to effect Early Settlement and shall instruct the Securities
Intermediary to Transfer all such Pledged Preferred Securities, the appropriate
Applicable Ownership Interest (as specified in clause (A) of the definition of
such term) of the Treasury Portfolio, Pledged Debentures or Pledged Treasury
Securities, as the case may be, to the Purchase Contract Agent for the benefit
of such Holders, in each case free and clear of the Pledge created hereby, for
distribution to such Holders in accordance with their respective interests.

     Section 5.7 Application of Proceeds Settlement. (a) If a Holder of
Corporate PIES (the Trust Preferred Securities or Debentures or security
entitlements to either of them are a component of the Corporate PIES) has not
elected to make an effective Cash Settlement by notifying the Purchase Contract
Agent in the manner provided for in Section 5.4(a)(i) in the Purchase Contract
Agreement, or has given such notice but failed to deliver the required cash
prior to 11:00 A.M., New York City time, on the fifth Business Day immediately
preceding the Purchase Contract Settlement Date, such Holder shall be deemed to
have elected to pay for the shares of Common Stock to be issued under such
Purchase Contract(s) from the Proceeds of the related Pledged Preferred
Securities or Pledged Debentures. In such event, the Collateral Agent shall
instruct the Securities Intermediary to Transfer the related Pledged Preferred
Securities or Pledged Debentures to the Remarketing Agent for remarketing. Upon
receiving such Pledged Preferred Securities or Pledged Debentures, the
Remarketing Agent, pursuant to the terms of the Remarketing Agreement, will use
its reasonable

                                                                              16


efforts to remarket such Pledged Preferred Securities or Pledged Debentures on
such date at a price of 100% of the aggregate liquidation amount of such Pledged
Preferred Securities or aggregate principal amount of such Pledged Debentures,
as the case may be. The Remarketing Agent will deposit the entire amount of the
Proceeds of such remarketing in the Collateral Account. On the Purchase Contract
Settlement Date, the Collateral Agent shall instruct the Securities Intermediary
to apply a portion of the Proceeds from such remarketing equal to the aggregate
liquidation amount of such Pledged Preferred Securities or aggregate principal
amount of such Pledged Debentures, as the case may be, to satisfy in full the
obligations of such Holders of Corporate PIES to pay the Purchase Price to
purchase the Common Stock under the related Purchase Contracts. The balance of
the Proceeds from such remarketing shall be transferred to the Purchase Contract
Agent for distribution to the Holders in accordance with their respective
interests. If the Remarketing Agent advises the Collateral Agent in writing that
there has been a Failed Remarketing, thus resulting in an event of default under
the Purchase Contract Agreement and hereunder, the Collateral Agent, for the
benefit of the Company shall, at the written direction of the Company, dispose
of the Pledged Preferred Securities or Pledged Debentures, as the case may be,
in accordance with applicable law and satisfy in full, from such disposition,
such Holders' obligations to pay the Purchase Price for the Common Stock.

     (b) If a Holder of Treasury PIES or Corporate PIES (if a Tax Event
Redemption has occurred) has not elected to make an effective cash settlement by
notifying the Purchase Contract Agent in the manner provided for in Section
5.4(d)(i) of the Purchase Contract Agreement, or has given such notice but
failed to make such payment in the manner required by Section 5.4(d)(ii) of the
Purchase Contract Agreement, such Holder shall be deemed to have elected to pay
for the shares of Common Stock to be issued under such Purchase Contract(s) from
the Proceeds of the related Pledged Treasury Securities or such Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio, as the case may be. Upon maturity of the Pledged
Treasury Securities or the Applicable Ownership Interest (as specified in clause
(A) of the definition of such term) of the Treasury Portfolio, the Securities
Intermediary, at the written direction of the Collateral Agent, shall invest the
Cash Proceeds of the maturing Pledged Treasury Securities or such Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio, as the case may be, in Permitted Investments. Without
receiving any instruction from any such Holder of Treasury PIES or Corporate
PIES, the Collateral Agent shall apply the Proceeds of the related Pledged
Treasury Securities or such Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) of the Treasury Portfolio to the
settlement of such Purchase Contracts on the Purchase Contract Settlement Date.
In the event the sum of the Proceeds from the related Pledged Treasury
Securities or such Applicable Ownership Interest (as specified in clause (A) of
the definition of such term) of the Treasury Portfolio and the investment
earnings from the investment in Permitted Investments is in excess of the
aggregate Purchase Price of the Purchase Contracts being settled thereby, the
Collateral Agent shall instruct the Securities Intermediary to distribute such
excess, when received, to the Purchase Contract Agent for the benefit of such
Holders for distribution to such Holders in accordance with their respective
interests.

     Section 5.8 Tax Event Redemption. If the Tax Event Redemption shall occur
prior to the Purchase Contract Settlement Date, the Securities Intermediary
shall apply the Redemption Amount to purchase the Treasury Portfolio and the
Securities Intermediary shall credit the Applicable

Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio to the Collateral Account and shall transfer the
Applicable Ownership Interest (as specified in clause (B) of the definition of
such term) of the Treasury Portfolio to the Purchase Contract Agent, free and
clear of any lien, pledge or security interest created hereby. Upon credit to
the Collateral Account of the Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) of the Treasury Portfolio having a
Value equal to the liquidation amount of the Pledged Preferred Securities or the
aggregate principal amount of the Pledged Debentures, the Securities
Intermediary shall release the Pledged Preferred Securities or the Pledged
Debentures, as applicable, from the Collateral Account and shall promptly
transfer the Pledged Preferred Securities to the Trust and the Pledged
Debentures to Capital Markets, as applicable.

     Section 6. Voting Rights -- Trust Preferred Securities and Pledged
Debentures. The Purchase Contract Agent may exercise, or refrain from
exercising, any and all voting and other consensual rights pertaining to the
Pledged Preferred Securities or the Pledged Debentures or any part thereof for
any purpose not inconsistent with the terms of this Agreement and in accordance
with the terms of the Purchase Contract Agreement; provided, that the Purchase
Contract Agent shall not exercise or, as the case may be, shall not refrain from
exercising such right if, in the judgment of the Purchase Contract Agent, such
action would impair or otherwise have a material adverse effect on the value of
all or any of the Pledged Preferred Securities or the Pledged Debentures; and
provided, further, that the Purchase Contract Agent shall give the Company and
the Collateral Agent at least five days' prior written notice of the manner in
which it intends to exercise, or its reasons for refraining from exercising, any
such right. Upon receipt of any notices and other communications in respect of
any Pledged Preferred Securities or any Pledged Debentures, including notice of
any meeting at which holders of the Trust Preferred Securities or Debentures are
entitled to vote or solicitation of consents, waivers or proxies of holders of
the Trust Preferred Securities or Debentures, the Collateral Agent shall use
reasonable efforts to send promptly to the Purchase Contract Agent such notice
or communication, and as soon as reasonably practicable after receipt of a
written request therefor from the Purchase Contract Agent, execute and deliver
to the Purchase Contract Agent such proxies and other instruments in respect of
such Pledged Preferred Securities or Pledged Debentures (in form and substance
satisfactory to the Collateral Agent) as are prepared by the Purchase Contract
Agent with respect to the Pledged Preferred Securities or Pledged Debentures.

     Section 7. Rights and Remedies; Distribution of the Debentures; Tax Event
Redemption.

     Section 7.1 Rights and Remedies of the Collateral Agent. (a) In addition to
the rights and remedies specified in Section 5.5 hereof or otherwise available

below) hereunder the Collateral Agent shall have all of the rights and remedies
with respect to the Collateral of a secured party under the Code (whether or not
the Code is in effect in the jurisdiction where the rights and remedies are
asserted) and the TRADES Regulations and such additional rights and remedies to
which a secured party is entitled under the laws in effect in any jurisdiction
where any rights and remedies hereunder may be asserted. Without limiting the

                                                                              18


satisfaction of the Holders' obligations under the Purchase Contracts or (ii)
sale of the Pledged Preferred Securities or Pledged Debentures in one or more
public or private sales.

     (b)  Without limiting any rights or powers otherwise granted by this
Agreement to the Collateral Agent, in the event the Collateral Agent is unable
to make payments to the Company on account of the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio or on account of principal payments of any Pledged
Treasury Securities as provided in Section 3 hereof, in satisfaction of the
Obligations of the Holder of the Securities of which such Pledged Treasury
Securities or the appropriate Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) of the Treasury Portfolio, as
applicable, is a part under the related Purchase Contracts, the inability to
make such payments shall constitute an event of default hereunder and the
Collateral Agent shall have and may exercise, with reference to such Pledged
Treasury Securities or such appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio, as applicable, and such Obligations of such Holder, any and all of
the rights and remedies available to a secured party under the Code and the
TRADES Regulations after default by a debtor, and as otherwise granted herein or
under any other law.

     (c)  Without limiting any rights or powers otherwise granted by this
Agreement to the Collateral Agent, the Collateral Agent is hereby irrevocably
authorized to receive and collect all payments of (i) the liquidation amount of,
or cash distributions on, the Pledged Preferred Securities, (ii) the principal
amount of the Pledged Treasury Securities, (iii) the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio and (iv) the principal amount of the Pledged
Debentures, subject, in each case, to the provisions of Section 3 hereof, and as
otherwise granted herein.

     (d)  The Purchase Contract Agent and each Holder of Securities, in the
event such Holder becomes the Holder of a Treasury PIES, agrees that, from time
to time, upon the written request of the Collateral Agent, the Purchase Contract
Agent or such Holder shall execute and deliver such further documents and do
such other acts and things as the Collateral Agent may reasonably request in
order to maintain the Pledge, and the perfection and priority thereof, and to
confirm the rights of the Collateral Agent hereunder. The Purchase Contract
Agent shall have no liability to any Holder for executing any documents or
taking any such acts requested by the Collateral Agent hereunder, except for
liability for its own negligent acts, its own negligent failure to act or its
own willful misconduct.

     Section 7.2 Substitution of Debentures. If the Trust shall have been
liquidated prior to the Purchase Contract Settlement Date, the Collateral Agent
shall transfer to the Securities Intermediary Debentures having a Value equal to
the liquidation amount of the Pledged Preferred Securities for credit to the
Collateral Account. Upon credit to the Collateral Account of such Debentures,
the Securities Intermediary shall release the Pledged Preferred Securities from
the Collateral Account and shall promptly transfer the same to the Trust.

     Section 7.3 Tax Event Redemption. Upon the occurrence of a Tax Event
Redemption prior to the Purchase Contract Settlement Date, the Redemption Price
payable on the Tax Event

                                                                              19


Redemption Date with respect to the Applicable Principal Amount shall be
credited to the Collateral Account by the Property Trustee or, if the Trust
shall have been dissolved and the related Debentures shall have been
distributed, by the Debenture Trustee on or prior to 12:30 p.m., New York City
time, by federal funds check or wire transfer of immediately available funds.
The Collateral Agent is hereby authorized to present the Pledged Preferred
Securities or the Pledged Debentures for payment as may be required by their
respective terms. Upon receipt of such funds, the Pledged Preferred Securities
or Pledged Debentures, as the case may be, shall be released from the Collateral
Account. In the event such funds are credited to the Collateral Account, the
Collateral Agent, at the written direction of the Company, shall instruct the
Securities Intermediary to (a) apply an amount equal to the Redemption Amount of
such Redemption Price to purchase the Treasury Portfolio from the Quotation
Agent for credit to the Collateral Account and (b) promptly remit the remaining
portion of such Redemption Price to the Purchase Contract Agent for payment to
the Holders of Corporate PIES, free and clear of any lien, pledge or security
interest created thereby.

     Section 7.4 Substitutions. Whenever a Holder has the right to substitute
Treasury Securities, Trust Preferred Securities, Debentures or security
entitlements to any of them or the appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio, as the case may be, for financial assets held in the Collateral
Account, such substitution shall not constitute a novation of the security
interest created hereby.

     Section 8. Representations and Warranties; Covenants.

     Section 8.1 Representations and Warranties. Each Holder from time to time,
acting through the Purchase Contract Agent as attorney-in-fact (it being
understood that the Purchase Contract Agent shall not be liable for any
representation or warranty made by or on behalf of a Holder), hereby represent
and warrant to the Collateral Agent (with respect to his interest in the
Collateral), which representations and warranties shall be deemed repeated on
each day a Holder Transfers Collateral that:

          (a)  such Holder has the power to grant a security interest in and
               lien on the Collateral;

          (b)  such Holder is the sole beneficial owner of the Collateral and,
               in the case of Collateral delivered in physical form, is the sole
               holder of such Collateral and is the sole beneficial owner of, or
               has the right to Transfer, the Collateral it Transfers to the
               Securities Intermediary for credit to the Collateral Account,
               free and clear of any security interest, lien, encumbrance, call,
               liability to pay money or other restriction other than the
               security interest and lien granted under Section 2 hereof;

          (c)  upon the Transfer of the Collateral to the Securities
               Intermediary for credit to the Collateral Account, the Collateral
               Agent, for the benefit of the Company, will have a valid and
               perfected first priority security interest therein (assuming that
               any central clearing operation or any securities intermediary or
               other entity not within the control of the Holder involved in

                                                                              20


               the Transfer of the Collateral, including the Collateral Agent
               and the Securities Intermediary, gives the notices and takes the
               action required of it hereunder and under applicable law for
               perfection of that interest and assuming the establishment and
               exercise of control pursuant to Section 4 hereof); and

          (d)  the execution and performance by the Holder of its obligations
               under this Agreement will not result in the creation of any
               security interest, lien or other encumbrance on the Collateral
               other than the security interest and lien granted under Section 2
               hereof or violate any provision of any existing law or regulation
               applicable to it or of any mortgage, charge, pledge, indenture,
               contract or undertaking to which it is a party or which is
               binding on it or any of its assets.

     Section 8.2 Covenants. The Holders from time to time, acting through the
Purchase Contract Agent as their attorney-in-fact (it being understood that the
Purchase Contract Agent shall not be liable for any covenant made by or on
behalf of a Holder), hereby covenant to the Collateral Agent that for so long as
the Collateral remains subject to the Pledge:

          (a)  neither the Purchase Contract Agent nor such Holders will create
               or purport to create or allow to subsist any mortgage, charge,
               lien, pledge or any other security interest whatsoever over the
               Collateral or any part of it other than pursuant to this
               Agreement; and

          (b)  neither the Purchase Contract Agent nor such Holders will sell or
               otherwise dispose (or attempt to dispose) of the Collateral or
               any part of it except for the beneficial interest therein,
               subject to the Pledge hereunder, transferred in connection with
               the Transfer of the Securities.

     Section 9. The Collateral Agent and the Securities Intermediary. It is
hereby agreed as follows:

     Section 9.1 Appointment, Powers and Immunities. The Collateral Agent shall
act as agent for the Company hereunder with such powers as are specifically
vested in the Collateral Agent by the terms of this Agreement, together with
such other powers as are reasonably incidental thereto. The Collateral Agent:
(a) shall have no duties or responsibilities except those expressly set forth in
this Agreement and no implied covenants or obligations shall be inferred from
this Agreement against the Collateral Agent, nor shall the Collateral Agent be
bound by the provisions of any agreement by any party hereto beyond the specific
terms hereof; (b) shall not be responsible for any recitals contained in this
Agreement, or in any certificate or other document referred to or provided for
in, or received by it under, this Agreement, the Securities or the Purchase
Contract Agreement, or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement (other than as against the
Collateral Agent), the Securities or the Purchase Contract Agreement or any
other document referred to or provided for herein or therein or for any failure
by the Company or any other Person (except the Collateral Agent) to perform any
of its obligations hereunder or


<PAGE>   24

                                                                              21


thereunder or for the perfection, priority or, except as expressly required
hereby, maintenance of any security interest created hereunder; (c) shall not be
required to initiate or conduct any litigation or collection proceedings
hereunder (except pursuant to directions furnished under Section 9.2 hereof,
subject to Section 9.6 hereof); (d) shall not be responsible for any action
taken or omitted to be taken by it hereunder or under any other document or
instrument referred to or provided for herein or in connection herewith or
therewith, except for its own negligence or willful misconduct; and (e) shall

refraining from taking any action with respect to, any securities or other
property deposited hereunder. Subject to the foregoing, during the term of this
Agreement, the Collateral Agent shall take all reasonable action in connection
with the safekeeping and preservation of the Collateral hereunder.

     No provision of this Agreement shall require the Collateral Agent to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder. In no event shall the Collateral
Agent be liable for any amount in excess of the Value of the Collateral.
Notwithstanding the foregoing, each of the Collateral Agent and the Securities
Intermediary in its individual capacity hereby waives any right of setoff,
bankers lien, liens or perfection rights as securities intermediary or any
counterclaim with respect to any of the Collateral.

     Section 9.2 Instructions of the Company. The Company shall have the right,
by one or more instruments in writing executed and delivered to the Collateral
Agent, to direct the time, method and place of conducting any proceeding for the
realization of any right or remedy available to the Collateral Agent, or of
exercising any power conferred on the Collateral Agent, or to direct the taking
or refraining from taking of any action authorized by this Agreement; provided,
however, that (i) such direction shall not conflict with the provisions of any
law or of this Agreement and (ii) the Collateral Agent shall be adequately
indemnified as provided herein. Nothing in this Section 9.2 shall impair the
right of the Collateral Agent in its discretion to take any action or omit to
take any action which it deems proper and which is not inconsistent with such
direction.

     Section 9.3 Reliance by Collateral Agent and Securities Intermediary. Each
of the Securities Intermediary and the Collateral Agent shall be entitled to
rely upon any certification, order, judgment, opinion, notice or other
communication (including, without limitation, any thereof by telephone,
telecopy, telex or facsimile) believed by it to be genuine and correct and to
have been signed or sent by or on behalf of the proper Person or Persons
(without being required to determine the correctness of any fact stated therein)
and upon advice and statements of legal counsel and other experts selected by
the Collateral Agent and the Securities Intermediary. As to any matters not ex
pressly provided for by this Agreement, the Collateral Agent and the Securities
Intermediary shall in all cases be fully protected in acting, or in refraining
from acting, hereunder in accordance with instructions given by the Company in
accordance with this Agreement.

     Section 9.4 Rights in Other Capacities. The Collateral Agent and the
Securities Intermediary and their affiliates may (without having to account
therefor to the Company) accept deposits from, lend money to, make their
investments in and generally engage in any kind of banking, trust or other
business with the Purchase Contract Agent, any other Person interested herein
and any Holder of Securities (and any of their respective subsidiaries or
affiliates) as if it were not acting as the Collateral Agent, and the Collateral
Agent, the Securities Intermediary and their affiliates may accept

                                                                              22


fees and other consideration from the Purchase Contract Agent and any Holder of
Securities without having to account for the same to the Company; provided that
each of the Securities Intermediary and the Collateral Agent covenants and
agrees with the Company that it shall not accept, receive or permit there to be
created in favor of itself and shall take no affirmative action to permit there
to be created in favor of any other Person, any security interest, lien or other
encumbrance of any kind in or upon the Collateral other than the lien created by
the Pledge.

     Section 9.5 Non-Reliance on Collateral Agent and Securities Intermediary.
Neither the Securities Intermediary nor the Collateral Agent shall be required
to keep itself informed as to the performance or observance by the Purchase
Contract Agent or any Holder of Securities of this Agreement, the Purchase
Contract Agreement, the Securities or any other document referred to or provided
for herein or therein or to inspect the properties or books of the Purchase
Contract Agent or any Holder of Securities. Neither the Collateral Agent nor the
Securities Intermediary shall have any duty or responsibility to provide the
Company with any credit or other information concerning the affairs, financial
condition or business of the Purchase Contract Agent or any Holder of Securi
ties (or any of their respective affiliates) that may come into the possession
of the Collateral Agent or the Securities Intermediary or any of their
respective affiliates.

     Section 9.6 Compensation and Indemnity. The Company agrees: (i) to pay the
Collateral Agent and the Securities Intermediary from time to time such
compensation as shall be agreed in writing between the Company and the
Collateral Agent or the Securities Intermediary, as the case may be, for all
services rendered by them hereunder and (ii) to indemnify the Collateral Agent
and the Securities Intermediary for, and to hold each of them harmless from and
against, any loss, liability or reasonable out-of-pocket expense incurred
without negligence, willful misconduct or bad faith on its part, arising out of
or in connection with the acceptance or administration of its powers and duties
under this Agreement, including the reasonable out-of-pocket costs and expenses
(including reasonable fees and expenses of counsel) of defending itself against
any claim or liability in connection with the exercise or performance of such
powers and duties.

     Section 9.7 Failure to Act. In the event of any ambiguity in the provisions
of this Agreement or any dispute between or conflicting claims by or among the
parties hereto or any other Person with respect to any funds or property
deposited hereunder, the Collateral Agent and the Securities Intermediary shall
be entitled, after prompt notice to the Company and the Purchase Contract Agent,
at its sole option, to refuse to comply with any and all claims, demands or
instructions with respect to such property or funds so long as such dispute or
conflict shall continue, and the Collateral Agent and the Securities
Intermediary shall not be or become liable in any way to any of the parties
hereto for its failure or refusal to comply with such conflicting claims,
demands or instructions. The Collateral Agent and the Securities Intermediary
shall be entitled to refuse to act until either (i) such conflicting or adverse
claims or demands shall have been finally determined by a court of competent
jurisdiction or settled by agreement between the conflicting parties as
evidenced in a writing satisfactory to the Collateral Agent or the Securities
Intermediary or (ii) the Collateral Agent or the Securities Intermediary shall
have received security or an indemnity satisfactory to it sufficient to save it
harmless from and against any and all loss, liability or reasonable
out-of-pocket expense which it may incur by reason of its acting. The Collateral
Agent and the Securities Intermediary may in addition elect to commence an
interpleader action or seek other judicial relief or orders as the

property held by it hereunder (including the Collateral) to such successor
Collateral Agent. The retiring Collateral Agent shall, upon such succession, be

Intermediary may be removed at any time by the Company and (iii) if the
Securities Intermediary fails to perform any of its material obligations
hereunder in any material respect for a period of not less than 20 days after
receiving written notice of such failure by the Purchase Contract Agent and such
failure shall be continuing, the Securities Intermediary may be removed by the
Purchase Contract Agent. The Purchase Contract Agent shall promptly notify the
Company of any removal of the Securities Intermediary pursuant to clause (iii)
of the immediately preceding sentence. Upon any such resignation or removal, the
Company shall have the right to appoint a successor Securities Intermediary. If
no successor Securities Intermediary shall have been so appointed and shall have
accepted such appointment within 30 days after the retiring Securities
Intermediary's giving of notice of resignation or such removal, then the

take all appropriate action to transfer any money and property held by it
hereunder (including the Collateral) to such successor Securities Intermediary.

from its duties and obligations as Securities Intermediary hereunder. After any
retiring Securities Intermediary's resignation hereunder as Securities
Intermediary, the provisions of this Section 9 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as the Securities Intermediary.

     Section 9.9 Right to Appoint Agent or Advisor. The Collateral Agent shall
have the right to appoint agents or advisors in connection with any of its
duties hereunder, and the Collateral Agent shall not be liable for any action
taken or omitted by, or in reliance upon the advice of, such agents or advisors

shall be subject to prior consent of the Company, which consent shall not be
unreasonably withheld.

termination of this Agreement and the resignation or removal of the Collateral

notwithstanding, in no event shall the Collateral Agent or the Securities
Intermediary or their officers, directors, employees or agents be liable under
this Agreement to any third party for indirect, special, punitive, or
consequential loss or damage of any kind whatsoever, including lost profits,
whether or not the likelihood of such loss or damage was known to the Collateral
Agent or the Securities Intermediary, or any of them, incurred without any act

          (2) to add to the covenants of the Company for the benefit of the

                                                                              25


          (3) to evidence and provide for the acceptance of appointment
     hereunder by a successor Collateral Agent, Securities Intermediary or
     Purchase Contract Agent; or

          (4) to cure any ambiguity (or formal defect), to correct or supplement
     any provisions herein which may be inconsistent with any other such
     provisions herein, or to make any other provisions with respect to such
     matters or questions arising under this Agreement, provided such action
     shall not adversely affect the interests of the Holders.

     Section 10.2 Amendment with Consent of Holders. With the consent of the
Holders of not less than a majority of the Purchase Contracts at the time
outstanding, by Act of said Holders delivered to the Company, the Purchase
Contract Agent, the Securities Intermediary or the Collateral Agent, as the case
may be, the Company, when duly authorized, the Purchase Contract Agent, the
Securities Intermediary and the Collateral Agent may amend this Agreement for
the purpose of modifying in any manner the provisions of this Agreement or the
rights of the Holders in respect of the Securities; provided, however, that no
such supplemental agreement shall, without the unanimous consent of the Holders
of each Outstanding Security adversely affected thereby,

          (1)  change the amount or type of Collateral underlying a Security
     (except for the rights of holders of Corporate PIES to substitute the
     Treasury Securities for the Pledged Preferred Securities, the Pledged
     Debentures or the appropriate Applicable Ownership Interest (as specified
     in clause (A) of the definition of such term) of the Treasury Portfolio, as
     the case may be, or the rights of Holders of Treasury PIES to substitute
     Trust Preferred Securities, Debentures or the appropriate Applicable
     Ownership Interest (as specified in clause (A) of the definition of such
     term) of the Treasury Portfolio, as applicable, for the Pledged Treasury
     Securities), impair the right of the Holder of any Security to receive
     distributions on the underlying Collateral or otherwise adversely affect
     the Holder's rights in or to such Collateral; or

          (2)  otherwise effect any action that would require the consent of the
     Holder of each Outstanding Security affected thereby pursuant to the
     Purchase Contract Agreement if such action were effected by an agreement
     supplemental thereto; or

          (3)  reduce the percentage of Purchase Contracts the consent of whose
     Holders is required for any such amendment;

provided that if any amendment or proposal referred to above would adversely
affect only the Corporate PIES or only the Treasury PIES, then only the affected
class of Holder as of the record date for the Holders entitled to vote thereon
will be entitled to vote on such amendment or proposal, and such amendment or
proposal shall not be effective except with the consent of Holders of not less
than a majority of such class; provided that the unanimous consent of the
Holders of each outstanding Purchase Contract of such class affected thereby
shall be required to approve any amendment or proposal specified in clauses
(1)-(3) above.

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

"Remarketing" means the remarketing of the Remarketed Securities pursuant to the
Remarketing Procedures.

          Section 1. Appointment and Obligations of the Remarketing Agent. (a)

aggregate liquidation or principal amount thereof, the Remarketed Securities
tendered or deemed tendered for purchase.

          (d) If, as a result of the efforts described in Section 1(b), the
Remarketing Agent determines that it will be able to remarket all Remarketed
Securities tendered or deemed tendered for purchase at a price of 100% of the
aggregate stated liquidation or principal amount of such Remarketed Securities
prior to 4:00 P.M., New York City time, on the Remarketing Date, the Remarketing
Agent shall determine the Reset Rate, which shall be the rate per annum (rounded

Remarketing Agent determines, in its sole judgment, to be the lowest rate per
annum that will enable it to remarket all Remarketed Securities tendered or
deemed tendered for Remarketing.

          (e) If none of the holders of Remarketed Securities elects to have
Remarketed Securities remarketed in the Remarketing, the Remarketing Agent shall

Remarketing Agent is unable to remarket all Remarketed Securities tendered or
deemed tendered for purchase, a failed Remarketing ("Failed Remarketing") shall
be deemed to have occurred, and the Remarketing Agent shall so advise by

     flood or other calamity, whether or not covered by insurance, or from any
     labor dispute or court or governmental action, order or decree, which
     could, individually or in the aggregate, reasonably be expected to have a
     material adverse effect on the general affairs, management, financial
     position, shareholders' equity or results of operations of the Company and
     its subsidiaries taken as a whole or upon the ability of the Issuers to
     perform their obligations under this Agreement (a "Material Adverse

     Exchange Act with the Commission on and after September 25, 1992, contain
     the information requested by the Staff in the Staff Response to be so
     included; and the supporting schedules included or incorporated by
     reference in the Prospectus or in any Remarketing Materials present fairly
     the information required to be stated therein.

          (p) Arthur Andersen LLP, who have certified certain financial
     statements of the Company, whose report appears in the Prospectus or is
     incorporated by reference therein or in any Remarketing Materials and who

     other than Liens permitted under the Indenture.

          (r) Other than as set forth or incorporated by reference in the
     Prospectus, there are no legal or governmental proceedings pending to which
     the Company or any of its subsidiaries is a party or to which any property
     or asset of the Company or any of its subsidiaries is the subject which
     could reasonably be expected individually or in the aggregate to have a
     Material Adverse Effect; and to the best of the Company's knowledge, no
     such proceedings are threatened or contemplated by governmental authorities
     or threatened by others.

          (s) The conditions for use of Form S-3, as set forth in the General
     Instructions thereto, have been satisfied.

          (t) There are no contracts or other documents which are required to be

     performance or observance of any term, covenant or condition contained in
     any material indenture, mortgage, deed of trust, loan agreement or other
     agreement or

                                                                               9

     instrument to which it is a party or by which it is bound or to which any
     of its properties or assets is subject, except where such defaults,
     individually or in the aggregate, could not reasonably be expected to have
     a Material Adverse Effect, or (iii) is in violation in any material respect
     of any law, ordinance, governmental rule, regulation or court decree to
     which it or its properties or assets may be subject or has failed to obtain
     any material license, permit, certificate, franchise or other governmental
     authorization or permit necessary to the ownership of its properties or
     assets or to the conduct of its business, except where such violations or
     failures, individually or in the aggregate, could not reasonably be
     expected to have a Material Adverse Effect.

     "investment company" within the meaning of such term under the Investment
     Company Act of 1940, as amended (the "1940 Act"), and the rules and
     regulations of the Commission thereunder; the Commission has issued an
     order (the "Order") exempting Capital Markets from all of the provisions of
     the 1940 Act; the Order is in full force and effect; and Capital Markets
     will continue to comply with the terms and conditions of the Order, or
     otherwise remain exempt from all of the provisions of the 1940 Act, so long
     as any Remarketed Securities are outstanding.

          (x) The Support Agreement has been duly authorized by Capital Markets
     and the Company and constitutes a valid and binding agreement of each of
     Capital Markets and the Company enforceable against Capital Markets and the
     Company in accordance with its terms, subject to the effects of bankruptcy,
     insolvency, fraudulent conveyance, reorganization, moratorium and other
     similar laws relating to or affecting creditors' rights generally, general
     equitable principles (whether considered in a proceeding in equity or at
     law) and an implied covenant of good faith and fair dealing; the Company's
     obligations under the Support Agreement will rank prior to the equity
     securities of the Company and equal with all other unsecured and
     unsubordinated indebtedness of the Company, whether now or hereafter
     outstanding; and the Debentures and the Guarantee will be entitled to the
     benefits of the Support Agreement, the obligations of Capital Markets under
     the Debentures and the Guarantee constitute "Debt" (as defined in the
     Support Agreement) for purposes of the Support Agreement, and the holders
     of the Debentures and the Guarantee will be entitled to the rights of
     "Lenders" (as defined in the Support Agreement) under the Support
     Agreement.

          (y) Each of the Company and each Significant Subsidiary has statutory
     authority, franchises and consents free from burdensome restrictions and
     adequate for the conduct of the business in which it is engaged.

          (z) Except for the Company's ownership of the voting securities of the
     Significant Subsidiaries, as and to the extent described in the Prospectus,
     no person or corporation which is a "holding company" or a "subsidiary
     company" of a "holding company" (as such terms are defined in the Public
     Utility Holding Company Act of 1935, as amended (the "1935 Act")), directly
     or indirectly owns, controls or holds with power to vote 10% or more of the
     outstanding voting securities of the Company or any Significant Subsidiary;

     to be on a consolidated basis to the extent the accounts of the Company and
     its subsidiaries are consolidated in reports furnished to the Company's
     shareholders generally or to the Commission).

          (h) Promptly from time to time to take such action as the Remarketing
     Agent may reasonably request to qualify any of the Remarketed Securities
     and the obligations of the Company under the Support Agreement for offering
     and sale under the securities laws of such jurisdictions as the Remarketing
     Agent may request and to comply with such laws so as to permit the
     continuance of sales and dealings therein in such jurisdictions for as long
     as may be necessary to complete the distribution of the Securities and the
     obligations of the Company pursuant to the Support Agreement; provided that
     in connection therewith, neither the Company nor Capital Markets shall be
     required to qualify as a foreign corporation or to file a general consent
     to service of process in any jurisdiction.

     6. Conditions to the Remarketing Agent's Obligations. The obligations of
the Remarketing Agent hereunder are subject to the accuracy, on and as of the
date when made, of the representations and warranties of the Company, Capital
Markets and the Trust contained herein, to the performance by the Company,
Capital Markets and the Trust of their respective obligations hereunder, and to
each of the following additional terms and conditions:

          (a) The Prospectus shall have been timely filed with the Commission;
     no stop order suspending the effectiveness of the Registration Statement or
     any part thereof or suspending the qualification of the Indenture, the
     Guarantee Agreement or the Declaration shall have been issued and no
     proceeding for that purpose shall have been initiated or threatened by the
     Commission; and any request of the Commission for inclusion of additional
     information in the Registration Statement or the Prospectus or otherwise
     shall have been complied with.

          (b) The Remarketing Agent shall not have discovered and disclosed to
     the Company on or prior to the Remarketing Date that the Prospectus, the
     Registration Statement, or the Remarketing Materials or any amendment or
     supplement thereto contains any untrue statement of a fact which, in the
     opinion of counsel for the Remarketing Agent, is material or omits to state
     any fact which, in the opinion of such counsel, is material and is required
     to be stated therein or is necessary to make the statements therein not
     misleading.

          (c) All corporate proceedings and other legal matters incident to the
     authorization, form and validity of this Agreement, the Declaration, the
     Indenture, the Remarketed Securities, the Guarantee Agreement, the
     Preferred Securities, the Common Securities, the Prospectus, the
     Registration Statement, the Remarketing Materials and all other legal
     matters relating to this Agreement and the transactions contemplated hereby
     shall be reasonably satisfactory in all material respects to counsel for
     the Remarketing Agent, and the Issuers shall have furnished to such counsel

     them to pass upon such matters.

          (d) Counsel to the Company and Capital Markets shall have furnished to
     the Remarketing Agent its written opinion, as counsel to the Company and
     Capital Markets, addressed to the Remarketing Agent and dated the
     Remarketing Date, in form and substance satisfactory to the Remarketing
     Agent, to the effect that:

               (i) The Company and each Significant Subsidiary have been duly
          incorporated and are validly existing as corporations in good standing
          under the laws of their respective jurisdictions of incorporation,
          with respective power and authority (corporate and other) to own their
          respective properties and conduct their businesses as described in the
          Prospectus.

               (ii) The Company has an authorized capitalization as set forth in
          the Prospectus and in any Remarketing Materials, all of the issued
          capital shares of the Company and each Significant Subsidiary of the

          paid and non-assessable; and all of the issued common shares of
          Northern Indiana and all of the issued capital shares of each other
          Significant Subsidiary (except for directors' qualifying shares and as
          set forth or incorporated by reference in the Registration Statement)
          are owned directly or indirectly by the Company, free and clear of all
          liens, encumbrances, equities or claims.

               (iii) The Company and each Significant Subsidiary has been duly
          qualified as a foreign corporation for the transaction of business and
          is in good standing under the laws of each other jurisdiction in which
          it owns or leases properties, or conducts any business, so as to
          require such qualification, or is subject to no material liability or
          disability by reason of the failure to be so qualified in any such
          jurisdiction.

               (iv) There are no preemptive or other rights to subscribe for or
          to purchase, nor any restriction upon the voting or transfer of the

          Company's or Capital Markets' charter or by-laws or any agreement or
          other instrument known to such counsel.

               (v) To the best of such counsel's knowledge and other than as set
          forth in the Prospectus or in any Remarketing Materials, there are no
          legal or governmental proceedings pending to which the Company or any
          of its subsidiaries is a party or to which any property or asset of
          the Company or any of its subsidiaries is subject which could
          reasonably be expected individually or in the aggregate to have a
          material adverse effect on the consolidated financial position,
          shareholders' equity or results of operations of the Company and its
          subsidiaries; and, to the best of such counsel's knowledge and other
          than as set forth in the Prospectus, no such proceedings are
          threatened or contemplated by governmental authorities or threatened
          by others.

               (vi) The Registration Statement was declared effective under the
          Securities Act, and the Indenture, the Declaration and the Guarantee
          Agreement were qualified under the Trust Indenture Act, as of the date

          Commission pursuant to the subparagraph of Rule 424(b) of the Rules
          and Regulations specified in such opinion on the date specified
          therein and, to the knowledge of such counsel, no stop order
          suspending the effectiveness of the Registration Statement has been
          issued and no proceeding for that purpose is pending or threatened by
          the Commission.

               (vii) Giving effect to the interpretations of the requirements of
          the Securities Act reflected in the No-Action Request and the Staff
          Response, the Registration Statement, as of its Effective Date, and
          the Prospectus, as of its date, and any further amendments or
          supplements thereto, as of their respective dates, made by the Company
          prior to the Purchase Contract Settlement Date (other than the
          financial statements, related schedules and other financial data
          contained therein, as to which such counsel need express no opinion)
          complied as to form in all material respects with the requirements of
          the Securities Act, the Rules and Regulations and the Trust Indenture
          Act; and the documents incorporated by reference in the Prospectus and
          any further amendment or supplement to any such incorporated document
          made by any of the Issuers prior to the Purchase Contract Settlement
          Date (other than the financial statements, related schedules and other
          financial data contained therein, as to which such counsel need
          express no opinion), when they became effective or were filed with the
          Commission, as the case may be, complied as to form in all material
          respects with the requirements of the Securities Act or the Exchange
          Act, as applicable, and the rules and regulations of the Commission
          thereunder; and the Indenture, the Declaration and the Guarantee
          Agreement conform in all material respects to the requirements of the
          Trust Indenture Act and the applicable rules and regulations
          thereunder.

               (viii) The statements contained in the Prospectus under the
          captions "Description of the Debentures," "Description of the
          Preferred Securities,"


<PAGE>   16
                                                                              16

          "Description of the Guarantee," "Relationship Among the Preferred
          Securities, the Debentures and the Guarantee" and "Description of the
          Support Agreement" insofar as they purport to constitute summaries of
          certain terms of documents referred to therein, constitute accurate
          summaries of the terms of such documents in all material respects.

               (ix) The Indenture has been duly authorized, executed and
          delivered by the Company and Capital Markets and (assuming due
          authentication, execution and delivery by the Indenture Trustee)
          constitutes a valid and binding agreement of each of the Company and
          Capital Markets enforceable against them in accordance with its terms,
          subject to the effects of bankruptcy, insolvency, fraudulent
          conveyance, reorganization, moratorium and other similar laws relating
          to or affecting creditors' rights generally, general equitable
          principles (whether considered in a proceeding in equity or at law)
          and an implied covenant of good faith and fair dealing.

               (x) The Debentures have been duly authorized, executed and
          delivered by Capital Markets and (assuming due authentication by the

          Markets entitled to the benefits of the Indenture and enforceable in
          accordance with their terms, subject to the effects of bankruptcy,
          insolvency, fraudulent conveyance, reorganization, moratorium and
          other similar laws relating to or affecting creditors' rights
          generally, general equitable principles (whether considered in a
          proceeding in equity or at law) and an implied covenant of good faith
          and fair dealing.

               (xi) The Declaration has been duly authorized, executed and
          delivered by Capital Markets.

               (xii) The Guarantee Agreement has been duly authorized, executed

          delivery by the Guarantee Trustee) constitutes a valid and binding
          agreement of Capital Markets enforceable against Capital Markets in
          accordance with its terms, subject to the effects of bankruptcy,
          insolvency, fraudulent conveyance, reorganization, moratorium and
          other similar laws relating to or affecting creditors' rights

          valid and binding agreement of the Company and Capital Markets
          enforceable in accordance with its terms, subject to the effects of
          bankruptcy, insolvency, fraudulent conveyance, reorganization,
          moratorium and other similar laws relating to or affecting creditors'
          rights generally, general equitable principles (whether considered in
          a proceeding in


<PAGE>   17
                                                                              17

          equity or at law) and an implied covenant of good faith and fair
          dealing; the Debentures and the Guarantee will be entitled to the
          benefits of the Support Agreement, the obligations of Capital Markets
          under the Debentures and the Guarantees will be deemed to be "Debt"
          for purposes of the Support Agreement and the holders of the
          Debentures and the Guarantee will be entitled to the rights of
          "Lenders" under the Support Agreement.

               (xv) The Transactions will not conflict with or result in a
          breach or violation of any of 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 the Trust, the Company or any of the Significant Subsidiaries
          is a party or by which the Trust, the Company or any of the
          Significant Subsidiaries is bound or to which any of the properties or
          assets of the Trust, the Company or any of the Significant
          Subsidiaries is subject, nor will such actions result in any violation
          of the provisions of the charter or by-laws of the Company or any of
          the Significant Subsidiaries or the Declaration or Certificate of
          Trust of the Trust or any statute, rule or regulation or any order
          known to such counsel of any court or governmental agency or body
          having jurisdiction over the Trust, the Company or any of the
          Significant Subsidiaries or any of their properties or assets; and,
          except for the registration of the Debentures, the Preferred
          Securities, the Guarantee, the Company's obligations under the Support
          Agreement under the Securities Act, the qualification of the
          Indenture, the Declaration and the Guarantee Agreement under the Trust
          Indenture Act, and such consents, approvals, authorizations,
          registrations or qualifications as may be required under the Exchange
          Act and applicable state securities laws, no consent, approval,
          authorization or order of, or filing or registration with, any such
          court or governmental agency or body is required for the Transactions.

               (xvi) None of the Trust nor the Company or any of its
          subsidiaries is an "investment company" or an entity "controlled" by
          an "investment company" as such terms are defined in the 1940 Act.

               (xvii) Based upon current law and the assumptions stated or
          referred to therein: (i) the Trust will be classified as a grantor
          trust for United States federal income tax purposes and not as an
          association taxable as a corporation; (ii) the Debentures will be
          classified as indebtedness of Capital Markets and (iii) the statements
          set forth in the Prospectus or in the Remarketing Materials under the
          caption "Certain United States Federal Income Tax Consequences"
          insofar as they purport to constitute summaries of matters of United
          States federal tax laws and regulations or legal conclusions with
          respect thereto, constitute accurate summaries of the matters
          described therein in all material respects.

     In rendering such opinion, such counsel may (i) state that its opinion is
     limited to matters governed by the Federal laws of the United States of
     America and the laws of the State of Indiana and New York (with respect to
     clause (x)) and (ii) rely (to the extent such counsel


<PAGE>   18

                                                                              18

          deems proper and specifies in its opinion), as to matters involving
          the application of the laws of the State of Massachusetts upon the
          opinion of local counsel. Such counsel shall also advise the
          Remarketing Agent that although such counsel is not passing upon and
          assumes no responsibility or liability for the accuracy, completeness
          or fairness of the statements contained in the documents incorporated
          by reference in the Prospectus or any further amendment or supplement
          thereto made by the Issuers prior to such Remarketing Date, they have
          no reason to believe that any of such documents (other than the
          financial statements and related schedules therein, as to which such
          counsel need express no opinion), when such documents became effective
          or were filed with the Commission, as the case may be, contained, in
          the case of a registration statement which became effective under the
          Securities Act, an untrue statement of a material fact or omitted to
          state a material fact required to be stated therein necessary to make
          the statements therein not misleading, or, in the case of other
          documents which were filed under the Securities 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. Such
          counsel shall also advise the Remarketing Agent that although such
          counsel is not passing upon and, except as set forth in clauses (viii)
          and (xvii) above, assumes no responsibility or liability for the
          accuracy, completeness or fairness of the statements contained in the
          Registration Statement, the Prospectus and the Remarketing Materials
          and any further amendments and supplements thereto made by the Issuers
          prior to such date, they have no reason to believe that, as of its
          effective date, the Registration Statement or any further amendment
          thereto made by the Issuers prior to such date (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 and the Remarketing
          Materials or any further amendment or supplement thereto made by the
          Issuers prior to such Remarketing Date (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 such Remarketing Date, either
          the Registration Statement, the Prospectus or the Remarketing
          Materials or any further amendment or supplement thereto made by the
          Issuers prior to such Remarketing Date (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 the Remarketing Materials or required to be
          described in the Registration Statement, the Prospectus or the
          Remarketing Materials which were not filed or incorporated by
          reference or described as required.

               (e) Special Delaware counsel to the Issuers shall have furnished
          to the Remarketing Agent its written opinion, as special Delaware
          counsel to the Issuers, addressed to the


<PAGE>   19
                                                                              19

          Remarketing Agent and dated the Remarketing Date, in form and
          substance satisfactory to the Remarketing Agent, to the effect that:

                    (i) The Trust has been duly created and is validly existing
               in good standing as a business trust under the Delaware Trust
               Act. Under the Delaware Trust Act and the Declaration, the Trust
               has the business trust power and authority to own property and to
               conduct its business as described in the Prospectus and the
               Remarketing Materials and to enter into and perform its
               obligations under this Agreement and the Trust Securities.

                    (ii) The Common Securities have been duly authorized by the
               Declaration and are validly issued and (subject to the terms in
               this paragraph) fully paid undivided beneficial interests in the
               assets of the Trust (such counsel may note that the holders of
               Common Securities will be subject to the withholding provisions
               of Section 10.4 of the Declaration, will be required to make
               payment or provide indemnity or security as set forth in the
               Declaration and will be liable for the debts and obligations of
               the Trust to the extent provided in Section 9.1(b) of the
               Declaration); under the Delaware Trust Act and the Declaration,
               the issuance of the Common Securities is not subject to
               preemptive rights.

                    (iii) The Preferred Securities have been duly authorized by
               the Declaration and are validly issued and (subject to the terms
               in this paragraph) fully paid and non-assessable undivided
               beneficial ownership interests in the assets of the Trust, the
               holders of the Preferred Securities will be entitled to the
               benefits of the Declaration (subject to the limitations set forth
               in clause (v) below) and will be entitled to the same limitation
               of personal liability as extended to stockholders of private
               corporations for profit organized under the General Corporation
               Law of the State of Delaware (such counsel may note that the
               holders of Preferred Securities will be subject to the
               withholding provisions of Section 10.4 of the Declaration and
               will be required to make payment or provide indemnity or security
               as set forth in the Declaration); under the Delaware Trust Act
               and the Declaration, the issuance of the Preferred Securities is
               not subject to preemptive rights.

                    (iv) Under the Delaware Trust Act and the Declaration all
               necessary trust action has been taken to duly authorize the
               execution, delivery and performance by the Trust of this
               Agreement.

                    (v) Assuming the Declaration has been duly authorized by
               Capital Markets and has been duly executed and delivered by
               Capital Markets and the Regular Trustees, and assuming due
               authorization, execution and delivery of the Declaration by the
               Property Trustee and the Delaware Trustee, the Declaration

               the Regular Trustees, enforceable against Capital Markets and the
               Regular Trustees in accordance with its terms, except to the
               extent that enforcement thereof may be limited by (i) bankruptcy,
               insolvency, moratorium, receivership, reorganization,
               liquidation,

               to or affecting the rights and remedies of creditors generally,
               (ii) principles of equity, including applicable law relating to
               fiduciary duties (regardless of whether considered and applied in
               a proceeding in equity or at law), and (iii) the effect of
               applicable public policy on the enforceability of provisions
               relating to indemnification or contribution.

                    (vi) The issuance and sale by the Trust of the Preferred
               Securities, the purchase by the Trust of the Debentures, the
               execution, delivery and performance by the Trust of this
               Agreement, the consummation by the Trust of the transactions
               contemplated by this Agreement and compliance by the Trust with
               its obligations thereunder do not violate any of the provisions
               of the Certificate of Trust or the Declaration or any applicable
               Delaware law or administrative regulation.

                    (vii) Assuming that the Trust derives no income from or
               connected with sources within the State of Delaware and has no
               assets, activities (other than having a Delaware Trustee as
               required by the Delaware Trust Act and the filing of documents
               with the Secretary of State of Delaware) or employees in the
               State of Delaware, no filing with, or authorization, approval,
               consent, license, order, registration, qualification or decree
               of, any Delaware court or Delaware governmental authority or
               agency (other that as may be required under the securities or
               blue sky laws of the state of Delaware, as to which such counsel
               need express no opinion) is necessary or required to be obtained
               by the Trust solely in connection with the due authorization,
               execution and delivery by the Trust of this Agreement or the
               offering, issuance, sale or delivery of the Preferred Securities.

          (f) Counsel to the Property Trustee and the Guarantee Trustee shall
     have furnished to the Remarketing Agent its written opinion, as counsel to
     The Chase Manhattan Bank, as Property Trustee and Guarantee Trustee,
     addressed to the Remarketing Agent and dated the Remarketing Date, in form
     and substance satisfactory to the Remarketing Agent, to the effect that:

               (i) Each of the Property Trustee and the Guarantee Trustee is
          duly incorporated as a New York banking corporation with all necessary
          power and authority to execute and deliver and perform their
          respective obligations under the terms of the Declaration and the

          Trustee of the Declaration and the execution, delivery and performance
          by the Guarantee Trustee of the Guarantee Agreement have been duly
          authorized by all necessary corporate action on the part of the
          Property Trustee and the Guarantee Trustee, respectively. The
          Declaration has been duly executed and delivered by the Property
          Trustee and the Guarantee Agreement has been duly executed and
          delivered by the Guarantee Trustee and each constitutes the valid and
          binding agreement of the Property Trustee and the Guarantee Trustee,
          respectively, enforceable against the Property Trustee and the
          Guarantee Trustee, respectively, in accordance with their

                                                                              21

          terms, subject to the effects of bankruptcy, insolvency, fraudulent
          conveyance, reorganization, moratorium and other similar laws relating
          to or affecting creditors' rights generally, general equitable
          principles (whether considered in a proceeding in equity or at law)
          and an implied covenant of good faith and fair dealing.

               (iii) The execution, delivery and performance of the Declaration
          and the Guarantee Agreement by the Property Trustee and the Guarantee
          Trustee, respectively, do not conflict with or constitute a breach of
          the charter or by-laws of the Property Trustee and the Guarantee
          Trustee, respectively.

               (iv) No consent, approval or authorization of, or registration

          Trustee and the Guarantee Trustee of the Declaration and the Guarantee
          Agreement, respectively.

          (g) Counsel to the Delaware Trustee shall have furnished to the
     Remarketing Agent its written opinion, as counsel to Chase Manhattan Bank
     Delaware, as Delaware Trustee, addressed to the Remarketing Agent and dated
     the Remarketing Date, in form and substance satisfactory to the Remarketing
     Agent, to the effect that:

               (i) The Delaware Trustee has been duly incorporated and is
          validly existing as a banking corporation in good standing under the
          laws of the State of Delaware with all necessary power and authority
          to execute and deliver, and to carry out and perform its obligations

          corporate action on the part of the Delaware Trustee. The Declaration
          has been duly executed and delivered by the Delaware Trustee and
          constitutes the valid and binding agreement of the Delaware Trustee
          enforceable against the Delaware Trustee in accordance with its terms,
          subject to (i) bankruptcy, insolvency, moratorium, receivership,
          reorganization, liquidation, fraudulent conveyance or transfer and
          other similar laws relating to or affecting the rights and remedies of
          creditors generally, (ii) principles of equity, including applicable
          law relating to fiduciary duties (regardless of whether considered and

          applicable public policy on the enforceability of provisions relating
          to indemnification or contribution.

               (iii) The execution, delivery and performance of the Declaration
          by the Delaware Trustee do not conflict with or constitute a breach of
          the charter or by-laws of the Delaware Trustee.

               (iv) No consent, approval or authorization of, or registration
          with or notice to, any Delaware or federal banking authority is

          (h) On the Remarketing Date, the Company shall have furnished to the
     Remarketing Agent a letter addressed to the Remarketing Agent and dated
     such date, in form and substance satisfactory to the Remarketing Agent, of
     Arthur Andersen LLP, or such other firm of nationally recognized
     independent public accountants satisfactory to the Remarketing Agent,
     containing statements and information of the type ordinarily included in
     accountants' "comfort letters" with respect to certain financial
     information contained in the Prospectus and in the Remarketing Materials.

          (i) Each of the Company and Capital Markets shall have furnished to
     the Remarketing Agent a certificate, dated the Remarketing Date, of, (i)
     with respect to the Company, (A) its Chairman of the Board and President,
     or its Executive Vice President, and (B) its chief financial officer, and
     (ii) with respect to Capital Markets, its President, and its chief
     financial officer, stating that:

               (i) The representations, warranties and agreements of the Company
          and Capital Markets in Sections 2 and 3 are true and correct as of the
          Remarketing Date; the Company and Capital Markets have complied with
          all its agreements contained herein; and the conditions contained in
          Section 6(a) have been fulfilled;

               (ii) (A) Neither the Company nor any of its subsidiaries has
          sustained since the date of the latest audited financial statements
          included or incorporated by reference in the Prospectus or in the
          Remarketing Materials 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, which could, individually or in the aggregate,
          reasonably be expected to have a Material Adverse Effect, otherwise
          than as set forth or contemplated in the Prospectus or in the
          Remarketing Materials and (B) since the respective dates as of which
          information is given in the Prospectus or in the Remarketing
          Materials, there has not been any material change in the consolidated
          share capital or long-term debt of the Company and its subsidiaries or
          the consolidated share capital or long-term debt of any Significant
          Subsidiary 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 the Company
          and its subsidiaries (taken as a whole), otherwise than as set forth
          or contemplated in the Prospectus or the Remarketing Materials; and

               (iii) They have carefully examined the Registration Statement,
          the Prospectus and the Remarketing Materials and, in their opinion (A)
          the Registration Statement, as of its effective date, and the
          Prospectus and the Remarketing Materials, as of their respective
          dates, did not include any untrue statement of a material fact and did
          not omit to state any material fact required to be stated therein or
          necessary to make the statements therein not misleading, and (B) since
          such dates, no event has occurred which should have been set forth in
          a supplement or amendment to the Registration Statement, the
          Prospectus or the Remarketing Materials.

          (j) (i) Neither the Company 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 and in the
     Remarketing Materials 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 or in the
     Remarketing Materials or (ii) since such date there shall not have been any
     change in the capital stock or long-term debt of the Company or any of its
     subsidiaries or any change, or any development involving a prospective
     change, in or affecting the general affairs, management, financial
     position, stockholders' equity or results of operations of the Company and
     its subsidiaries, otherwise than as set forth or contemplated in the
     Prospectus or in the Remarketing Materials, the effect of which, in any
     such case described in clause (i) or (ii), is, in the judgment of the
     Remarketing Agent, so material and adverse as to make it impracticable or
     inadvisable to proceed with the Remarketing on the terms and in the manner
     contemplated in the Prospectus and in the Remarketing Materials.

          (k) Without the prior written consent of the Remarketing Agent, the
     Declaration or the Indenture shall not have been amended in any manner, or
     otherwise contain any provision contained therein as of the date hereof
     that, in the opinion of the Remarketing Agent, materially changes the
     nature of the Remarketed Securities or the Remarketing Procedures.

          (l) Subsequent to the execution and delivery of this Agreement, (i) no
     downgrading shall have occurred in the rating accorded the Preferred
     Securities or any of the Company's, any Significant Subsidiary's or Capital
     Markets' 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 Securities 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 the Preferred
     Securities or any of the Company's, any Significant Subsidiary's or Capital
     Markets' debt securities.

          (m) Subsequent to the execution and delivery of this Agreement, there
     shall not have occurred any of the following: (i) trading in securities
     generally on the New York Stock Exchange or the American Stock Exchange or
     in the over-the-counter market, or trading in any securities of the Company
     or Capital Markets on any exchange or in the over-the-counter market, shall
     have been suspended or minimum prices shall have been established on any
     such exchange or such market by the Commission, by such exchange or by any
     other regulatory body or governmental authority having jurisdiction, (ii) a
     banking moratorium shall have been declared by Federal or state
     authorities, (iii) the United States shall have become engaged in
     hostilities, there shall have been an escalation in hostilities involving
     the United States or there shall have been a declaration of a national
     emergency or war by the United States or (iv) there shall have occurred
     such a material adverse change in general economic, political or financial
     conditions (or the effect of international conditions on the financial
     markets in the United States shall be such) as to make it, in the judgment
     of the Remarketing Agent, impracticable or inadvisable to proceed with the
     Remarketing on the terms and in the manner contemplated in the Prospectus
     or in the Remarketing Materials.

          All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Remarketing Agent.

          7. Indemnification and Contribution. (a) The Issuers shall indemnify
and hold harmless the Remarketing Agent, its officers and employees and each
person, if any, who controls the Remarketing Agent within the meaning of the
Securities Act, from and against any loss, claim, damage or liability, joint or
several, or any action in respect thereof (including, but not limited to, any
loss, claim, damage, liability or action relating to purchases and sales of the
Remarketed Securities), to which the Remarketing Agent or that officer, employee
or controlling person may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained (A) in any Preliminary Prospectus, the Registration Statement,
the Prospectus or the Remarketing Materials or in any amendment or supplement
thereto, or (B) in any blue sky application or other document prepared or
executed by the Issuers (or based upon any written information furnished by the
Issuers) specifically for the purpose of qualifying any or all of the Remarketed
Securities under the securities laws of any state or other jurisdiction (any
such application, document or information being hereinafter called a "Blue Sky
Application"), or (ii) the omission or alleged omission to state in any
Preliminary Prospectus, the Registration Statement, the Prospectus or the
Remarketing Materials or in any amendment or supplement thereto, or in any Blue
Sky Application, any material fact required to be stated therein or necessary to
make the statements therein not misleading and shall reimburse the Remarketing
Agent and each such officer, employee and controlling person promptly upon
demand for any legal or other expenses reasonably incurred by the Remarketing
Agent or that officer, employee or controlling person in connection with
investigating or defending or preparing to defend against any such loss, claim,
damage, liability or action as such expenses are incurred; provided however,
that the Issuers shall not be liable in any such case to the extent that any
such loss, claim, damage, liability or action arises out of, or is based upon,
any untrue statement or alleged untrue statement or omission or alleged omission
made in any Preliminary Prospectus, the Registration Statement, the Prospectus
or the Remarketing Materials or in any such amendment or supplement, or in any
Blue Sky Application in reliance upon and in conformity with the written
information furnished to the Issuers by or on behalf of the Remarketing Agent
specifically for inclusion therein and described in a letter from the
Remarketing Agent to the Company and provided further, that as to any
Preliminary Prospectus this indemnity agreement shall not inure to the benefit
of the Remarketing Agent, its officers or employees or any person controlling
the Remarketing Agent on account of any loss, claim, damage, liability or action
arising from the sale of the Remarketed Securities to any person by the
Remarketing Agent if the Remarketing Agent failed to send or give a copy of the
Prospectus, as the same may be amended or supplemented, to that person within
the time required by the Securities Act, and the untrue statement or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact in such Preliminary Prospectus was corrected in the Prospectus,
unless such failure resulted from non- compliance by the Company with Section
5(c). For purposes of the last proviso to the immediately preceding sentence,
the term "Prospectus" shall not be deemed to include the documents incorporated
therein by reference, and the Remarketing Agent shall not be obligated to send
or give any supplement or amendment to any document incorporated by reference in
any Preliminary Prospectus or the Prospectus to any person other than a person
to whom the Remarketing Agent had


<PAGE>   25
                                                                              25


delivered such incorporated document or documents in response to a written
request therefor. The foregoing indemnity agreement is in addition to any
liability which the Issuers may otherwise have to the Remarketing Agent or to
any officer, employee or controlling person of the Remarketing Agent.

          (b) The Remarketing Agent shall indemnify and hold harmless the
Company and Capital Markets, their officers and employees, each of their
directors, the Trust and each Trustee, and each person, if any, who controls any
of the Issuers within the meaning of the Securities Act, from and against any
loss, claim, damage or liability, joint or several, or any action in respect
thereof, to which the Company or Capital Markets, any such director, officer or
employee, the Trust or any such Trustee or any such controlling person may
become subject, under the Securities Act or otherwise, insofar as such loss,
claim, damage, liability or action arises out of, or is based upon, (i) any
untrue statement or alleged untrue statement of a material fact contained (A) in
any Preliminary Prospectus, the Registration Statement, the Prospectus or the
Remarketing Materials or in any amendment or supplement thereto, or (B) in any
Blue Sky Application or (ii) the omission or alleged omission to state in any
Preliminary Prospectus, the Registration Statement, the Prospectus or the
Remarketing Materials or in any amendment or supplement thereto, or in any Blue
Sky Application, any material fact required to be stated therein or necessary to
make the statements therein not misleading, but in each case only to the extent
that the untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with the written
information furnished to the Company or the Trustee by or on behalf of the
Remarketing Agent specifically for inclusion therein and described in a letter
from the Remarketing Agent to the Company and Capital Markets, and shall
reimburse the Company and Capital Markets and any such director, officer or
employee, the Trust or any such Trustee or such controlling person for any legal
or other expenses reasonably incurred by the Company or Capital Markets or any
such director or officer, the Trust or any Trustee or any such controlling
person in connection with investigating or defending or preparing to defend
against any such loss, claim, damage, liability or action as such expenses are
incurred. The foregoing indemnity agreement is in addition to any liability
which the Remarketing Agent may otherwise have to the Company or Capital Markets
or any such director or officer, the Trust or any such Trustee or any such
controlling person.

          (c) Promptly after receipt by an indemnified party under this Section
7 of notice of any claim or the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 7, notify the indemnifying party in
writing of the claim or the commencement of that action; provided however, that
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 7 except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified party otherwise than under this Section 7.
If any such claim or action shall be brought against an indemnified party, and
it shall notify the indemnifying party thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it wishes, jointly with
any other similarly notified indemnifying party, to assume the defense thereof
with counsel satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 7 for any legal or other expenses
subsequently


<PAGE>   26
                                                                              26

incurred by the indemnified party in connection with the defense thereof other
than reasonable costs of investigation; provided however, that the Remarketing
Agent shall have the right to employ counsel to represent jointly the
Remarketing Agent and its officers, employees and controlling persons who may be
subject to liability arising out of any claim in respect of which indemnity may
be sought by the Remarketing Agent against the Issuers under this Section 7 if,
in the reasonable judgment of the Remarketing Agent, it is advisable for the
Remarketing Agent and those officers, employees and controlling persons to be
jointly represented by separate counsel, and in that event the fees and expenses
of such separate counsel shall be paid by the Issuers. No indemnifying party
shall (i) without the prior written consent of the indemnified parties (which
consent shall not be unreasonably withheld), settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding, or (ii) be
liable for any settlement of any such action effected without its written
consent (which consent shall not be unreasonably withheld), but if settled with
its written consent or if there be a final judgment of the plaintiff in any such
action, the indemnifying party agrees to indemnify and hold harmless any
indemnified party from and against any loss or liability by reason of such
settlement or judgment.

          (d) If the indemnification provided for in this Section 7 shall for
any reason be unavailable to or insufficient to hold harmless an indemnified
party under Section 7(a) or 7(b) in respect of any loss, claim, damage or
liability, or any action in respect thereof, referred to therein, then each
indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Issuers on the one hand and the Remarketing Agent on the other
hand from the Remarketing or (ii) if the allocation provided by clause (i) above
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also
the relative fault of the Issuers on the one hand and the Remarketing Agent on
the other with respect to the statements or omissions which resulted in such
loss, claim, damage or liability, or action in respect thereof, as well as any
other relevant equitable considerations. The relative benefits received by the
Issuers on the one hand and the Remarketing Agent on the other with respect to
such offering shall be deemed to be in the same proportion as the total
liquidation or principal amount of the Remarketed Securities less the fee paid
to the Remarketing Agent pursuant to Section 4(a) of this Agreement, on the one
hand, and the total fees received by the Remarketing Agent pursuant to such
Section 4(a), on the other hand, bear to the total liquidation or principal
amount of the Remarketed Securities. The relative fault shall be determined by
reference to whether the untrue or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact relates to information
supplied by the Issuers on the one hand or the Remarketing Agent on the other
hand, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Remarketing Agent agree that it would not be just and
equitable if contributions pursuant to this Section 7(d) were to be determined
by pro rata allocation or by any other method of allocation which does not take
into account the equitable considerations referred to herein. The amount paid or
payable by an

                                                                              27

indemnified party as a result of the loss, claim, damage or liability, or action
in respect thereof, referred to above in this Section 7(d) shall be deemed to
include, for purposes of this Section 7(d), 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

amount in excess of the amount by which the fees received by it under Section 4
exceed the amount of any damages which the Remarketing Agent has otherwise paid
or become liable to pay by reason of any untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to

Depositary, the Property Trustee and the Indenture Trustee and, in the case of a
removal, the removed Remarketing Agent, the Depositary, the Property Trustee and
the Indenture Trustee; provided however, that (i) Capital Markets may not remove
the Remarketing Agent unless (A) the Remarketing Agent becomes involved as a
debtor in a bankruptcy, insolvency or similar proceeding, (B) the Remarketing
Agent shall not be among the 15 underwriters with the largest volume
underwritten in dollars, on a lead or co-managed basis, of U.S. domestic debt

one or more legal restrictions preventing the performance of its obligations
hereunder and (ii) no such resignation nor any such removal shall become

recognized broker-dealer as successor Remarketing Agent and such successor
Remarketing Agent shall have entered into a remarketing agreement with the
Company, Capital Markets and the Trust in which it shall have agreed to conduct
the Remarketing in accordance with the Remarketing Procedures. In any such case,
Capital Markets will use its reasonable efforts to appoint a successor
Remarketing Agent and enter into such a remarketing agreement with such person

any action which any beneficial owner of Remarketed Securities may be entitled
to exercise or take pursuant to the Declaration or the Indenture with like
effect as if it did not act in any capacity hereunder. The Remarketing Agent, in
its individual capacity, either as principal or agent, may also engage in or

obligations of the Remarketing Agent shall be determined solely by the express
provisions of this Agreement and the Declaration and the Indenture. No implied

communication reasonably believed by it to have been signed, presented or made
by the proper party or parties. The Remarketing Agent, acting under this
Agreement, shall incur no liability to the Company or to any holder of
Remarketed Securities in its individual capacity or as Remarketing Agent for any
action or failure to act, on its part in connection with a Remarketing or

     Benefit in an amount equal to the amount determined pursuant to clause (i)
     below less the amount determined pursuant to clause (ii) below:

               (i) the aggregate monthly amount of the pension benefit
          ("Pension") that would have been payable to Executive under all
          Pension Plans if that Pension were computed (A) by treating the
          Severance Period as service for all purposes of the Pension Plans and
          (B) by considering his compensation during the Severance Period to be
          his Base Salary and one-twelfth of his Bonus for all purposes of the
          Pension Plans;

               (ii) the aggregate monthly amount of any Pension actually paid to
          Executive under all Pension Plans.

               (B) The Supplemental Pension Benefit payable to Executive
     hereunder shall be paid (i) commencing at the later to occur of the last

     Pension payable to Executive under the Pension Plans.

               (C) If Executive dies prior to commencement of payment to him of
     his Pension under the Pension Plans, under circumstances in which a death
     benefit under the Pension Plans is payable to his surviving spouse or other
     beneficiary, then Employer shall pay a monthly Supplemental Death Benefit
     to Executive's surviving spouse or other beneficiary entitled to receive
     the death benefit payable with respect to Executive under the

                                       7
<PAGE>   8


     Pension Plans in an amount equal to the amount determined pursuant to
     clause (i) below less the amount determined pursuant to clause (ii) below:

               (i) the aggregate monthly amount of the death benefit that would
          have been payable to the surviving spouse or other beneficiary of
          Executive under the Pension Plans if that death benefit were computed
          (A) by treating the Severance Period as service for all purposes of
          the Pension Plans and (B) by considering his compensation during the
          Severance Period to be his Base Salary and one-twelfth of his Bonus
          for all purposes of the Pension Plans;

               (ii) the aggregate monthly amount of any death benefit actually
          paid to the surviving spouse or other beneficiary of Executive under
          the Pension Plans.

               (D) The Supplemental Death Benefit payable with respect to
     Executive hereunder shall be payable at the same time, in the same form,
     and to the same persons as is applicable to the death benefit payable with
     respect to Executive under the Pension Plans.

               (E) Notwithstanding the foregoing provisions, the total of the
     actual years of service of Executive for purposes of each of the Pension
     Plans and the years of service for which credit is given pursuant to
     subparagraphs (3)(A) and (C) shall not exceed the maximum number of years
     of service, if any, that can be considered pursuant to the terms of such
     Pension Plan.

               (F) Any actuarial adjustments made under the Pension Plans with
     respect to the form or time of payment of a Pension or death benefit to
     Executive or his surviving spouse or other beneficiary under the Pension
     Plans shall also be applicable to the

                                       8
<PAGE>   9


     Supplemental Pension Benefit or Supplemental Death Benefit payable
     hereunder and shall be based upon the same actuarial assumptions as those
     specified in the Pension Plans.

          (5) If upon the date of termination of Executive's employment
     Executive holds any options with respect to stock of Employer, all such
     options will immediately become exercisable upon such date and will be
     exercisable for 200 days thereafter. Any restrictions on stock of Employer
     owned by Executive on the date of termination of his employment will lapse
     on such date.

          (6) During the Severance Period Executive and his spouse and other
     dependents will continue to be covered by all Welfare Plans maintained by
     Employer in which he and his spouse and other dependents were participating
     immediately prior to the date of his termination as if he continued to be
     an employee of Employer and Employer will continue to pay the costs of
     coverage of Executive and his spouse and other dependents under such
     Welfare Plans on the same basis as is applicable to active employees
     covered thereunder; provided that, if participation in any one or more of
     such Welfare Plans is not possible under the terms thereof, Employer will
     provide substantially identical benefits. Coverage under any such Welfare
     Plan will cease if and when Executive obtains employment with another
     employer during the Severance Period, and becomes eligible for coverage
     under any substantially similar Welfare Plan provided by his new employer.

          (7) During the Severance Period, Executive shall not be entitled to
     reimbursement for fringe benefits, including without limitation, dues and
     expenses related to club memberships, automobile expenses, expenses for
     professional services and other similar perquisites.

     (b) If the employment of Executive with Employer is terminated by Employer
or Executive other than under circumstances set forth in subsection 3(a),
Executive's Base Salary shall be paid through the date of his termination, and
Employer shall have no further obligation to Executive or any other person under
this Agreement. Such termination shall have no effect upon Employee's other
rights, including but not limited to, rights under the Retirement Plans and the
Welfare Plans.

     (c) Notwithstanding anything herein to the contrary, (1) in the event
Employer shall terminate the employment of Executive for Good Cause hereunder,
Employer shall give Executive at least thirty (30) days prior written notice
specifying in detail the reason or reasons for Executive's termination, and (2)
in the event Executive terminates his employment for Good Reason hereunder,
Executive shall give Employer at least thirty (30) days prior written notice
specifying in detail the reason or reasons for Executive's termination.

     (d) This Agreement shall have no effect, and Employer shall have no
obligations hereunder, if Executive's employment terminates for any reason at
any time other than during the 24 months following a Change in Control.

     4. Excise Tax. (a) In the event that a Change in Control shall occur, and a
final determination is made by legislation, regulation, ruling directed to
Executive or Employer, by court decision, or by independent tax counsel
described in subsection (b) next below, that the aggregate amount of any payment
made to Executive (1) hereunder, and (2) pursuant to any plan, program or policy
of Employer in connection with, on account of, or as a result of, such Change in
Control ("Total Payments") will be subject to the excise tax provisions of
Section 4999 of the Code, or any successor section thereof, Executive shall be
entitled to receive from Employer, in addition to any

                                      10
<PAGE>   11


other amounts payable hereunder, a lump sum payment (the "Gross-Up Payment"),
sufficient to cover the full cost of such excise taxes and Executive's federal,
state and local income and employment taxes on this additional payment so that
the net amount retained by Executive, after the payment of all such excise taxes
on the Total Payments, and all federal, state and local income and employment
taxes and excise taxes on the Gross-Up Payment, shall be equal to the Total
Payments. The Total Payments, however, shall be subject to any federal, state
and local income and employment taxes thereon. For this purpose, Executive shall
be deemed to be in the highest marginal rate of federal, state and local taxes.
The Gross-Up Payment shall be made at the same time as the payments described in
subsections 3(a)(1) and (2) above.

     (b) Employer and Executive shall mutually and reasonably determine the
amount of the Gross-Up Payment to be made to Executive pursuant to the preceding
subsection. Prior to the making of any such Gross-Up Payment, either party may
request a determination as to the amount of such Gross-Up Payment. If such a
determination is requested, it shall be made promptly, at Employer's expense, by
independent tax counsel selected by Executive and approved by Employer (which
approval shall not unreasonably be withheld), and such determination shall be
conclusive and binding on the parties. Employer shall provide such information
as such counsel may reasonably request, and such counsel may engage accountants
or other experts at Employer's expense to the extent that they deem necessary or
advisable to enable them to reach a determination. The term "independent tax
counsel," as used herein, shall mean a law firm of recognized expertise in
federal income tax matters that has not previously advised or represented either
party. It is hereby agreed that neither Employer nor Executive shall engage any
such firm as counsel for any purpose, other

                                      11
<PAGE>   12


than to make the determination provided for herein, for three years following
such firm's announcement of its determination.

     (c) In the event the Internal Revenue Service subsequently adjusts the
excise tax computation made pursuant to subsections 4(a) and (b) above, Employer
shall pay to Executive, or Executive shall pay to Employer, as the case may be,
the full amount necessary to make either Executive or Employer whole had the
excise tax initially been computed as subsequently adjusted, including the
amount of any underpaid or overpaid excise tax, and any related interest and/or
penalties due to the Internal Revenue Service.

     5. Setoff. No payments or benefits payable to or with respect to Executive
pursuant to this Agreement shall be reduced by any amount Executive or his
spouse or Beneficiary, or any other beneficiary under the Pension Plans, may
earn or receive from employment with another employer or from any other source,
except as expressly provided in subsection 3(a)(6).

     6. Death. If Executive's employment with Employer terminates under
circumstances described in subsections 3(a) or (b), then upon Executive's
subsequent death, all unpaid amounts payable to Executive under subsections
3(a)(1), (2) or (3) or 3(b), or Section 4, if any, shall be paid to his
Beneficiary, all amounts payable under subsection 3(a)(4) shall be paid pursuant
to the terms of said subsection to his spouse or other beneficiary under the
Pension Plans, and if subsection 3(a) applies, his spouse and other dependents
shall continue to be covered under all applicable Welfare Plans during the
remainder of the Severance Period, if any, pursuant to subsection 3(a)(6).

     7. No Solicitation of Representatives and Employees. Executive agrees that
he shall not, during the Term or the Severance Period, directly or indirectly,
in his individual capacity or otherwise, induce, cause, persuade, or attempt to
do any of the foregoing in order to cause, any

                                      12
<PAGE>   13


representative, agent or employee of Employer or any of its Affiliates to
terminate such person's employment relationship with Employer or any of its
Affiliates, or to violate the terms of any agreement between said
representative, agent or employee and Employer or any of its Affiliates.

     8. Confidentiality. Executive acknowledges that preservation of a
continuing business relationship between Employer or its Affiliates and their
respective customers, representatives, and employees is of critical importance
to the continued business success of Employer and its Affiliates and that it is
the active policy of Employer and its Affiliates to guard as confidential
certain information not available to the public and relating to the business
affairs of Employer and its Affiliates. In view of the foregoing, Executive
agrees that he shall not during the Term and at any time thereafter, without the
prior written consent of Employer, disclose to any person or entity any such
confidential information that was obtained by Executive in the course of his
employment by Employer or any of its Affiliates. This section shall not be
applicable if and to the extent Executive is required to testify in a
legislative, judicial or regulatory proceeding pursuant to an order of Congress,
any state or local legislature, a judge, or an administrative law judge or is
otherwise required by law to disclose such information.

     9. Forfeiture. If Executive shall at any time violate any obligation of his
under Sections 7 or 8 in a manner that results in material damage to the
Employer or its business, he shall immediately forfeit his right to any benefits
under this Agreement, and Employer shall thereafter have no further obligation
hereunder to Executive or his spouse, Beneficiary or any other person.

     10. Executive Assignment. No interest of Executive, his spouse or any
Beneficiary, or any other beneficiary under the Pension Plans, under this
Agreement, or any right to receive any payment or distribution hereunder, shall
be subject in any manner to sale, transfer, assignment,

                                      13
<PAGE>   14


pledge, attachment, garnishment, or other alienation or encumbrance of any kind,
nor may such interest or right to receive a payment or distribution be taken,
voluntarily or involuntarily, for the satisfaction of the obligations or debts
of, or other claims against, Executive or his spouse, Beneficiary or other
beneficiary, including claims for alimony, support, separate maintenance, and
claims in bankruptcy proceedings.

     11. Benefits Unfunded. Except as otherwise provided in Section 13, all
rights under this Agreement of Executive and his spouse, Beneficiary or other
beneficiary under the Pension Plans, shall at all times be entirely unfunded,
and no provision shall at any time be made with respect to segregating any
assets of Employer for payment of any amounts due hereunder. None of Executive,
his spouse, Beneficiary or any other beneficiary under the Pension Plans shall
have any interest in or rights against any specific assets of Employer, and
Executive and his spouse, Beneficiary or other beneficiary shall have only the
rights of a general unsecured creditor of Employer. Except as otherwise provided
in Section 13, and notwithstanding the preceding provisions of this Section, the
Nominating and Compensation Committee of the Board of Directors of Employer, in
its discretion, shall have the right, at any time and from time to time, to
cause amounts payable to Executive or his Beneficiary hereunder to be paid to
the trustee of the NIPSCO Industries, Inc. Umbrella Trust For Management
established effective January 1, 1991, as amended from time to time, or any
similar trust at any time established by Employer ("Trust").

     12. Waiver. No waiver by any party at any time of any breach by the other
party of, or compliance with, any condition or provision of this Agreement to be
performed by such other party shall be deemed a waiver of any other provisions
or conditions at the same time or at any prior or subsequent time.

                                      14
<PAGE>   15


     13. Litigation Expenses. Employer shall pay Executive's reasonable
attorneys' fees and legal expenses in connection with any judicial proceeding to
enforce this Agreement, or to construe or determine the validity of this
Agreement or otherwise in connection therewith, whether or not Executive is
successful in such litigation. Within 10 days following the occurrence of a
Potential Change in Control (as defined in the Trust described in Section 11),
the Nominating and Compensation Committee of the Board of Directors of Employer
shall cause Employer to contribute the sum of $100,000 to the Trust to be
applied in satisfaction of Employer's obligations under this Section. The
Nominating and Compensation Committee shall cause Employer to contribute
additional amounts to the Trust, at such time or times as the Committee deems
appropriate, to the extent the aggregate of (1) the aforementioned sum of
$100,000, plus Trust earnings thereon, and (2) any additional Employer
contributions to the Trust, plus Trust earnings thereon, is not sufficient to
satisfy in full Employer's obligations under this Section.

     14. Applicable Law. This Agreement shall be construed and interpreted
pursuant to the laws of Indiana.

     15. Entire Agreement. This Agreement contains the entire Agreement between
the Employer and Executive and supersedes any and all previous agreements;
written or oral; between the parties relating to the subject matter hereof. No
amendment or modification of the terms of this Agreement shall be binding upon
the parties hereto unless reduced to writing and signed by Employer and
Executive.

     16. No Employment Contract. Nothing contained in this Agreement shall be
construed to be an employment contract between Executive and Employer.

                                      15
<PAGE>   16



     17. Counterparts. This Agreement may be executed in counterparts, each of
which shall be deemed an original.

     18. Severability. In the event any provision of this Agreement is held
illegal or invalid, the remaining provisions of this Agreement shall not be
affected thereby.

     19. Successors. This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective heirs, representatives and
successors.

     20. Employment with an Affiliate. For purposes of this Agreement, (A)
employment or termination of employment of Executive shall mean employment or
termination of employment with Employer and all Affiliates, (B) Base Salary and
Bonus shall include remuneration received by Executive from Employer and all
Affiliates, and (C) the terms Pension Plan, Retirement Plan and Welfare Plan
maintained or made available by Employer shall include any such plans of any
Affiliate of Employer.

     21. Notice. Notices required under this Agreement shall be in writing and
sent by registered mail, return receipt requested, to the following addresses or

              Schedule of Parties to Change of Control Agreements

     The following NiSource executives have entered into amended Change in
Control and Termination Agreements with Industries: Gary L. Neale, Stephen P.
Adik, Patrick J. Mulchay, Jeffrey W. Yundt, Joseph L. Turner, James K. Abcouwer,
Jerry L. Godwin, David A. Kelly, Mark T. Maassel, Thomas J. Aruffo, Peggy
Landini, Mark D. Wyckoff and Robert J. Schacht. The contracts are substantially
identical in all material respects except as to the parties, the execution dates
and the amount of time following a change of control that the termination
provisions of the agreement apply (from 7-24 months). In addition, Mr. Adik's
and Mr. Neale's agreements provide that if a change of control occurs during the
term of the agreement, they may terminate their employment within 24 months for
any reason; and Mr. Neale's agreement provides that he will receive termination
benefits during the term of the agreement (regardless of whether a change of
control has occurred) if he is terminated for any reason other than for good
cause, if he terminates his employment for good reason or if his employment
terminates due to death or disability.

     WHEREAS, pursuant to Section 9.1 of the Plan, the Company deems it to be in
its best interest to amend the Plan as described below;

     NOW, THEREFORE, the Plan is hereby amended, effective April 1, 1999, as
follows:

     1.   The Plan is renamed the NiSource Inc. Nonemployee Director Stock
Incentive Plan;

     2.   The second sentence of Section 6.7 is amended to read as follows:

          Regardless of the vesting schedule set forth above, all Shares of
     Restricted Stock held by a Participant shall immediately become one hundred
     percent (100%) vested upon the first to occur of the following:

          (a)  The completion of the vesting schedule set forth above;

          (b)  The death of the Participant;
          (c)  The Disability of the Participant;
          (d)  The retirement of the Participant from service on the Board prior
               to death or Disability and after attaining the age of seventy
               (70) years; or
          (e)  The effective date of a Change in Control of the Company.

     3.   Section 6.8 is amended to read as follows:

          6.8 TERMINATION OF DIRECTORSHIP. In the event a Participant ceases to

     Participant ceases to be a Director by reason of death, Disability or
     retirement, all Shares of Restricted Stock granted under the Plan shall
     immediately vest one hundred percent (100%).

     4. The second sentence of Section 7.5 is amended to read as follows:

          (b)  The death of the Participant;
          (c)  The Disability of the Participant;

     be a Director for any reason other than death, Disability or retirement (as
     defined in Section 7.5(d)), all Options not vested as of the effective date
     of termination shall be forfeited and shall revert back to the Company

     date shall remain exercisable for six (6) months following the date the
     Director's service on the Board terminates, or until their expiration date,
     whichever period is shorter.

          In the event a Participant dies, incurs a Disability or ceases service
     on the Board due to retirement, prior to termination of any of his Options
     without having fully exercised such Option, the Participant, or his legal
     representative, beneficiary, heir or legatee, shall have the right to
     exercise such unexercised Option during its term within a period of one
     year after the date of such termination due to death, Disability or
     retirement, or during such other period and subject to such terms as may be
     determined by the Board. Options which vest pursuant to a Change in Control
     shall remain exercisable throughout their entire term.

                            LONG-TERM INCENTIVE PLAN

               (AS AMENDED AND RESTATED EFFECTIVE APRIL 14, 1999)


         WHEREAS, NIPSCO Industries, Inc. (the "Company") adopted the NIPSCO
Industries, Inc. Long-Term Incentive Plan effective April 13, 1988, as last
amended and restated effective February 1, 1998; and

         WHEREAS, pursuant to Section 21 of the Plan, the Company wishes to
further amend the Plan in certain respects and restate it in a single document;

         NOW THEREFORE, the Plan is hereby amended and restated, effective April
14, 1999, as follows:

         1. PURPOSE. The purpose of the NIPSCO Industries, Inc., Long-Term
Incentive Plan (the "Plan") is to further the earnings of NIPSCO Industries,
Inc. (the "Company"), its subsidiaries and their subsidiaries. The Plan provides
long-term incentives to those officers and key executives who make substantial
contributions by their ability, loyalty, industry and invention. The Company
intends that the Plan will thereby facilitate securing, retaining, and
motivating management employees of high caliber and potential.

         2. ADMINISTRATION AND DELEGATION. The Plan shall be administered by the
Nominating and Compensation Committee ("Committee") of the Board of Directors of
the Company ("Board"). The Committee shall be composed of not fewer than two
members of the Board who are "nonemployee directors" of the Company within the
meaning of Rule 16b-3 under the Securities Exchange Act of 1934, as amended
("1934 Act"), and "outside directors" of the Company within the meaning of
Section 162(m) of the Internal Revenue Code of 1986, as amended, and the
regulations thereunder. Subject to the express provisions of the Plan, the
Committee may interpret the Plan, prescribe, amend and rescind rules and
regulations relating to it, determine the terms and provisions of awards to
officers and other key executive employees under the Plan (which need not be
identical), and make such other determinations as it deems necessary or
advisable for the administration of the Plan. The decisions of the Committee
under the Plan shall be conclusive and binding. No member of the Board or of the
Committee shall be liable for any action taken, or determination made, hereunder
in good faith. Service on the Committee shall constitute service as a director
of the Company so that members of the Committee shall be entitled to
indemnification and reimbursement as directors of the Company, pursuant to its
by-laws.

         3. REVIEW AND APPROVAL. Specific performance goals and details for an
award program shall be promulgated by the Committee after consideration of the
recommendations of the chief executive officer and shall be submitted to the
Board for approval by the majority vote of directors who are not otherwise
employed as officers or employees.

         4. SHARES SUBJECT TO PLAN. Subject to the provisions of section 20, the
shares of common stock of the Company that may be issued, or may be the measure
of stock appreciation rights granted, under the Plan shall not exceed in the
aggregate 2,500,000 (5,000,000 after January 30, 1998) of the common shares
without par value of the Company ("Shares"). Such Shares may be authorized and
unissued Shares or treasury Shares. Except as otherwise provided herein, any
Shares subject to an option or right which for any reason expires or is
terminated, unexercised as to such Shares, shall again be available under the
Plan.

         5. PARTICIPANTS. Persons eligible to participate shall be limited to
those officers and other key executive employees who are in positions in which
their decisions, actions and counsel significantly impact upon profitability.
Directors who are not otherwise officers or employees shall not be eligible to
participate in the Plan.

         6. AWARDS UNDER THE PLAN. Awards under the Plan may be in the form of
stock options (both options designed to satisfy statutory requirements necessary
to receive favorable tax treatment pursuant to any future legislation and
options not designed to so qualify under any such future legislation), incentive
stock options, stock appreciation rights, performance units, and restricted
Shares or such combinations of the above as the Committee may in its discretion
deem appropriate.

         7. SECTION 162(m) LIMITATIONS. Subject to Section 20 of the Plan, the
maximum number of stock options and stock appreciation rights granted to any
person who qualifies as an executive officer named from time to time in the
summary compensation table in the Company's annual meeting proxy statement and
who is employed by the Company on the last day of the taxable year (the "SCT
Executives") shall be 350,000 during the term of the Plan.

         8. NONQUALIFIED STOCK OPTIONS. Options shall be evidenced by stock
option agreements in such form and not inconsistent with the Plan as the
Committee shall approve from time to time, which agreements shall contain in
substance the following terms and conditions:

                  (a) OPTION PRICE. The purchase price per Share deliverable
         upon the exercise of an option shall not be less than 100% of the fair
         market value of the Share on the day the option is granted, as
         determined by the Committee. For purposes of the Plan, fair market
         value shall be the average of the high and low prices on the New York
         Stock Exchange Composite Transactions on the date of the grant.

                  (b) EXERCISE AT OPTION. Each stock option agreement shall
         state the period or periods of time within which the option may be
         exercised by the optionee, in whole or in part, which shall be such
         period or periods of time as may be determined by the Committee,
         provided that the option period shall not commence earlier than six
         months after the date of the grant of the option nor end later than ten
         years after the date of the grant of the option. The Committee shall
         have the power to permit in its discretion an acceleration of the
         previously determined exercise terms, within the terms of the Plan,
         under such circumstances and upon such terms and conditions as it deems
         appropriate.

                  (c) PAYMENT FOR SHARES. Except as otherwise provided in the
         Plan or in any stock option agreement, the optionee shall pay the
         purchase price of the Shares upon the exercise of any option (i) in
         cash, (ii) in cash received from a broker-dealer to whom the optionee
         has submitted an exercise notice consisting of a fully endorsed option
         (however in the case of an optionee subject to Section 16 of the 1934
         Act, this payment option shall only be available to the extent such
         payment procedures comply with Regulation T issued by the Federal
         Reserve Board), (iii) by delivering Shares having an aggregate fair
         market value on the date of exercise equal to the option exercise
         price, (iv) by directing the Company to withhold such number of Shares
         otherwise issuable upon exercise of such option having an aggregate
         fair market value on the date of exercise equal to the option exercise
         price, (v) by such other medium of payment as the Committee, in its
         discretion, shall authorize at the time of grant, or (vi) by any
         combination of (i), (ii), (iii), (iv) and (v). In the case of an
         election pursuant to (i) or (ii) above, cash shall mean cash or check
         issued by a federally insured bank or savings and loan association, and
         made payable to NIPSCO Industries, Inc. In the case of payment pursuant
         to (ii), (iii) or (iv) above, the optionee's election must be made on
         or prior to the date of exercise and shall be irrevocable. In lieu of a
         separate election governing each exercise of an option, an optionee may
         file a blanket election with the Committee which shall govern all
         future exercises of options until revoked by the optionee. The Company
         shall issue, in the name of the optionee, stock certificates
         representing the total number of Shares issuable pursuant to the
         exercise of any option as soon as reasonably practicable after such
         exercise, provided that any Shares purchased by an optionee through a
         broker-dealer pursuant to clause (ii) above, shall be delivered to such
         broker-dealer in accordance with 12 C.F.R. ss. 220.3(e)(4), or other
         applicable provision of law.

                  (d) TRANSFERABILITY. Each stock option agreement shall provide
         that the option subject thereto is not transferable by the optionee
         otherwise than by will or the laws of descent or distribution.
         Notwithstanding the preceding sentence, an optionee, at any time prior
         to his death, may assign all or any portion of the option to (i) his
         spouse or lineal descendant, (ii) the trustee of a trust for the
         primary benefit of his spouse or lineal descendant, or (iii) a
         tax-exempt organization as described in Section 501(c)(3) of the
         Internal Revenue Code of 1986, as amended. In such event the spouse,
         lineal descendant, trustee or tax-exempt organization will be entitled
         to all of the rights of the optionee with respect to the assigned
         portion of such option, and such portion of the option will continue to
         be subject to all of the terms, conditions and restrictions applicable
         to the option as set forth herein, and in the related stock option
         agreement, immediately prior to the effective date of the assignment.
         Any such assignment will be permitted only if (i) the optionee does not
         receive any consideration therefor, and (ii) the assignment is
         expressly approved by the Committee or its delegate. Any such
         assignment shall be evidenced by an appropriate written document
         executed by the optionee, and a copy thereof shall be delivered to the
         Committee or its delegate on or prior to the effective date of the
         assignment. This paragraph shall apply to all nonqualified stock
         options granted under the Plan at any time.

                  (e) RIGHTS UPON TERMINATION AT EMPLOYMENT. In the event that
         an optionee ceases to be an employee for any reason other than death,
         disability or retirement, the optionee shall have the right to exercise
         the option during its term within a period of thirty days after such
         termination to the extent that the option was exercisable at the date
         of such termination of employment, or during such other period and
         subject to such terms as may be determined by the Committee. In the
         event that an optionee dies, retires, or becomes disabled prior to
         termination of his option without having fully exercised his option,
         the optionee or his successor shall have the right to exercise the
         option during its term within a period of twelve months after the date
         of such termination due to death, disability or retirement, to the
         extent that the option was exercisable at the date of termination due
         to death, disability or retirement, or during such other period and
         subject to such terms as may be determined by the Committee. For
         purposes of the Plan, the term "disability" shall mean the inability of
         an individual to engage in any substantial gainful activity by reason
         of any medically determinable physical or mental impairment which is
         expected to result in death or which has lasted or can be expected to
         last for a continuous period of not less than twelve (12) months. The
         Committee, in its sole discretion, shall determine the date of any
         disability. For purposes of the Plan, the term "retirement" shall mean
         retirement as defined in the Company's pension plan.

         9. INCENTIVE STOCK OPTIONS. Incentive stock options shall be evidenced
by stock option agreements in such form and not inconsistent with the Plan as
the Committee shall approve from time to time, which agreements shall contain in
substance the following terms and conditions:

                  (a) OPTION PRICE. The purchase price per Share of stock
         deliverable upon the exercise of an option shall not be less than 100%
         of the fair market value (as defined in subsection 8(a)) of the stock
         on the day the option is granted, as determined by the Committee except
         as provided in Section 9(b).

                  (b) EXERCISE OF OPTION. Each stock option agreement shall
         state the period or periods of time within which the option may be
         exercised by the optionee, in whole or in part, which shall be such
         period or periods of time as may be determined by the Committee,
         provided that the option period shall not commence earlier than six
         months after the date of the grant of the option nor end later than ten
         years after the date of the grant of the option. The aggregate fair
         market value (determined with respect to each incentive stock option at
         the time of grant) of the Shares with respect to which incentive stock
         options are exercisable for the first time by an individual during any
         calendar year (under all incentive stock option plans of the Company
         and its parent and subsidiary corporations) shall not exceed $100,000.
         If the aggregate fair market value (determined at the time of grant) of
         the Shares subject to an option, which first becomes exercisable in any
         calendar year exceeds the limitation of this Section 9(b), so much of
         the option that does not exceed the applicable dollar limit shall be an
         incentive stock option and the remainder shall be a nonqualified stock
         option; but in all other respects, the original option agreement shall
         remain in full force and effect. As used in this Section 9, the words
         "parent" and "subsidiary" shall have the meanings given to them

                                       -4-

<PAGE>   8



         in Section 425(e) and 425(f) of the Internal Revenue Code of 1986, as
         amended. Notwithstanding anything herein to the contrary, if an
         incentive stock option is granted to an individual who owns stock
         possessing more than ten percent (10%) of the total combined voting
         power of all classes of stock of the Company or of its parent or
         subsidiary corporations, within the meaning of Section 422(b)(6) of the
         Internal Revenue Code of 1986, as amended, (i) the purchase price of
         each Share subject to the incentive stock option shall be not less than
         one hundred ten percent (110%) of the fair market value of the Shares
         on the date the incentive stock option is granted, and (ii) the
         incentive stock option shall expire and all rights to purchase Shares
         thereunder shall cease no later than the fifth anniversary of the date
         the incentive stock option was granted.

                  (c) PAYMENT FOR SHARES. Except as otherwise provided in the
         Plan or in any stock option agreement, the optionee shall pay the
         purchase price of the Shares upon the exercise of any option, (i) in
         cash, (ii) in cash received from a broker-dealer to whom the optionee
         has submitted an exercise notice consisting of a fully endorsed option
         (however in the case of an optionee subject to Section 16 of the 1934
         Act, this payment option shall only be available to the extent such
         payment procedures comply with Regulation T issued by the Federal
         Reserve Board), (iii) by delivering Shares having an aggregate fair
         market value on the date of exercise equal to the option exercise
         price, (iv) by directing the Company to withhold such number of Shares
         otherwise issuable upon exercise of such option having an aggregate
         fair market value on the date of exercise equal to the option exercise
         price, (v) by such other medium of payment as the Committee, in its
         discretion, shall authorize at the time of grant, or (vi) by any
         combination of (i), (ii), (iii), (iv) and (v). In the case of an
         election pursuant to (i) or (ii), cash shall mean cash or check issued
         by a federally insured bank or savings and loan association, and made
         payable to NIPSCO Industries, Inc. In the case of payment pursuant to
         (ii), (iii) or (iv) above, the optionee's election must be made on or
         prior to the date of exercise and shall be irrevocable. In lieu of a
         separate election governing each exercise of an option, an optionee may
         file a blanket election with the Committee which shall govern all
         future exercises of options until revoked by the optionee. The Company
         shall issue, in the name of the optionee, stock certificates
         representing the total number of Shares issuable pursuant to the
         exercise of any option as soon as reasonably practicable after such
         exercise, provided that any Shares purchased by an optionee through a
         broker-dealer pursuant to clause (ii) above, shall be delivered to such
         broker-dealer in accordance with 12 C.F.R. ss. 220.3(e)(4), or other
         applicable provision of law.

                  (d) TRANSFERABILITY. Each stock option agreement shall provide
         that it is not transferable by the optionee otherwise than by will or
         the laws of descent or distribution.

                  (e) RIGHTS UPON TERMINATION OF EMPLOYMENT. In the event that
         an optionee ceases to be an employee for any reason, the optionee (or
         in the case of his death, his beneficiary or personal representative)
         shall have the right to exercise the option during the term within a
         period of ninety days (or in the case of termination of employment
         because of disability, within a period of one year) after such
         termination to the extent that the option was

                                       -5-

<PAGE>   9



         exercisable at the date of such termination of employment, or during
         such other period and subject to such terms as may be determined by the
         Committee.

The provisions of this section 9 shall be construed and applied, and (subject to
the limitations of Section 21) shall be amended from time to time so as to
comply with Section 422 of the Internal Revenue Code of 1986, as amended, or its
successors and regulations issued thereunder.

         10. STOCK APPRECIATION RIGHTS. Stock appreciation rights shall be
evidenced by stock appreciation right agreements in such form and not
inconsistent with the Plan as the Committee shall approve from time to time,
which agreements shall contain in substance the following terms and conditions:

                  (a) AWARD. A stock appreciation right shall entitle the
         grantee to receive upon exercise the excess of (i) the fair market
         value of a specified number of Shares at the time of exercise over (ii)
         a specified price which shall not be less than 100% of the fair market
         value of the Shares at the time the stock appreciation right was
         granted, or, if connected with a previously issued stock option, not
         less than 100% of the fair market value of the Shares at the time such
         option was granted. A stock appreciation right may be granted in
         connection with all or any portion of a previously or contemporaneously
         granted stock option or not in connection with a stock option.

                  (b) TERM. Stock appreciation rights shall be granted for a
         period of not less than one year nor more than ten years, and shall be
         exercisable in whole or in part, at such time or times and subject to
         such other terms and conditions as shall be prescribed by the Committee
         at the time of grant, subject to the following:

                           (i) No stock appreciation right shall be exercisable
                  in whole or in part, during the six month period starting with
                  the date of grant; and

                           (ii) Stock appreciation rights will be exercisable
                  only during a grantee's employment, except that in the
                  discretion of the Committee a stock appreciation right may be
                  made exercisable for up to thirty days after the grantee's
                  employment is terminated for any reason other than death,
                  disability or retirement. In the event that a grantee dies,
                  retires, or becomes disabled without having fully exercised
                  his stock appreciation rights, the grantee or his successor
                  shall have the right to exercise the stock appreciation rights
                  during their term within a period of twelve months after the
                  date of such termination due to death, disability or
                  retirement to the extent that the right was exercisable at the
                  date of such termination, or during such other period and
                  subject to such terms as may be determined by the Committee.

                           The Committee shall have the power to permit in its
                  discretion an acceleration of previously determined exercise
                  terms, within the terms of the Plan,

                                       -6-

<PAGE>   10



                  under such circumstances and upon such terms and conditions as
                  it deems appropriate.

                  (c) PAYMENT. Upon exercise of a stock appreciation right,
         payment shall be made in cash, in the form of Shares at fair market
         value, or in a combination thereof, as the Committee may determine.

         11. PERFORMANCE UNITS. Performance Units ("Units") shall be evidenced
by performance unit agreements in such form and not inconsistent with the Plan
as the Committee shall approve from time to time, which agreements shall contain
in substance the following terms and conditions:

                  (a) PERFORMANCE PERIOD. At the time of award, the Committee
         shall establish with respect to each Unit award a performance period of
         not less than two, nor more than five years.

                  (b) VALUATION OF UNITS. At the time of award, the Committee
         shall establish with respect to each such award a value for each Unit
         which shall not thereafter change, or which may vary thereafter
         determinable from criteria specified by the Committee at the time of
         award.

                  (c) PERFORMANCE TARGETS. At the time of award, the Committee
         shall establish maximum and minimum performance targets to be achieved
         with respect to each award during the performance period. The
         participant shall be entitled to payment with respect to all Units
         awarded if the maximum target is achieved during the performance
         period, but shall be entitled to payment with respect to a portion of
         the Units awarded according to the level of achievement of performance
         targets, as specified by the Committee, for performance during the
         performance period which meets or exceeds the minimum target but fails
         to meet the maximum target.

                  The performance targets established shall relate to corporate,
         division, or unit performance and may be established in terms of (i)
         changes in stock price, gross revenue, pre-tax operating income, or
         earnings per share; or (ii) ratios of stock price, earnings, or pre-
         tax operating income relative to shareholder's equity, earnings, total
         assets, or to assets employed; or (iii) a comparison of any of the
         preceding measures to similar measures for competitors. Multiple
         targets may be used and may have the same or different weighting, and
         they may relate to absolute performance or relative performance as
         measured against other institutions or divisions or units thereof.

                  (d) ADJUSTMENTS. At any time prior to payment of the Units,
         the Committee may adjust previously established performance targets and
         other terms and conditions, including the corporation's, or division's
         or unit's financial performance for Plan purposes, to reflect major
         unforeseen events such as changes in laws, regulations or accounting
         practices,

         mergers, acquisitions or divestitures or extraordinary, unusual or
         non-recurring items or events.

                  (e) PAYMENTS OF UNITS. Following the conclusion of each
         performance period, the Committee shall determine the extent to which
         performance targets have been attained for such period as well as the
         other terms and conditions established by the Committee. The Committee
         shall determine what, if any, payment is due on the Units. Payment
         shall be made in cash, in the form of Shares at fair market value, or a
         combination thereof, as the Committee may determine.

                  (f) TERMINATION OF EMPLOYMENT. In the event that a participant
         holding a Unit award ceases to be an employee prior to the end of the
         applicable performance period by reason of death, disability or
         retirement, his Units, to the extent earned under the applicable
         performance targets, shall be payable at the end of the performance
         period in proportion to the active service of the participant during
         the performance period, as determined by the Committee. Upon any other
         termination of employment, participation shall terminate forthwith and
         all outstanding Units held by the participant shall be canceled.

                  (g) OTHER TERMS. The Unit agreements shall contain such other
         terms and provisions and conditions not inconsistent with the Plan as
         shall be determined by the Committee.

         12. RESTRICTED STOCK AWARDS. Restricted Stock Awards under the Plan
shall be in the form of Shares of the Company, restricted as to transfer and
subject to forfeiture, and shall be evidenced by restricted stock agreements in
such form and not inconsistent with the Plan as the Committee shall approve from
time to time, which agreements shall contain in substance the following terms
and conditions:

                  (a) RESTRICTION PERIOD. Shares awarded pursuant to the Plan
         shall be subject to such terms, conditions, and restrictions, including
         without limitation: prohibitions against transfer, substantial risks of
         forfeiture, attainment of performance objectives and repurchase by the
         Company or right of first refusal, and for such period or periods as
         shall be determined by the Committee at the time of grant. The
         Committee shall have the power to permit in its discretion, an
         acceleration of the expiration of the applicable restriction period
         with respect to any part or all of the Shares awarded to a participant.

                  (b) RESTRICTIONS UPON TRANSFER. Shares awarded, and the right
         to vote such Shares and to receive dividends thereon, may not be sold,
         assigned, transferred, exchanged, pledged, hypothecated, or otherwise
         encumbered, except as herein provided, during the restriction period
         applicable to such Shares. Subject to the foregoing, and except as
         otherwise provided in the Plan, the participant shall have all the
         other rights of a shareholder including, but not limited to, the right
         to receive dividends and the right to vote such Shares.


                                       -8-

<PAGE>   12



         The performance objectives established by the Committee shall relate to
         corporate, division or unit performance, and may be established in
         terms of (i) changes in stock price, gross revenue, pre-tax operating
         income, or earnings per share; or (ii) ratios of stock price, earnings,
         or pre-tax operating income relative to shareholder's equity, earnings,
         total assets, or to assets employed; or (iii) a comparison of any of
         the preceding measures to similar measures for competitors. Multiple
         objectives may be used and may have the same or different weighting,
         and they may relate to absolute performance or relative performance as
         measured against other institutions or divisions or units thereof.

                  (c) CERTIFICATES. Each certificate issued in respect of Shares
         awarded to a participant shall be deposited with the Company, or its
         designee, and shall bear the following legend:

         "This certificate and the shares represented hereby are subject to the
         terms and conditions (including forfeiture and restrictions against
         transfer) contained in the NIPSCO Industries, Inc. Long-Term Incentive
         Plan and an Agreement entered into by the registered owner. Release
         from such terms and conditions shall obtain only in accordance with the
         provisions of the Plan and Agreement, a copy of each of which is on
         file in the office of the Secretary of said Company."

                  (d) LAPSE OF RESTRICTIONS. The Agreement shall specify the
         terms and conditions upon which any restrictions upon Shares awarded
         under the Plan shall lapse, as determined by the Committee. Upon the
         lapse of such restrictions, Shares, free of the foregoing restrictive
         legend, shall be issued to the participant or his legal representative.

                  (e) TERMINATION PRIOR TO LAPSE OF RESTRICTIONS. In the event
         of a participant's termination of employment, other than due to death
         or retirement, prior to the lapse of restrictions applicable to any
         Shares awarded to such participant, all Shares as to which there still
         remains unlapsed restrictions shall be forfeited by such participant
         without payment of any consideration to the participant, and neither
         the participant nor any successors, heirs, assigns, or personal
         representatives of such participant shall thereafter have any further
         rights or interest in such Shares or certificates.

         13. SUPPLEMENTAL CASH PAYMENTS. Subject to the Company's discretion,
stock option, incentive stock option, stock appreciation right, performance unit
or restricted stock agreements may provide for the payment of a supplemental
cash payment to a participant promptly after the exercise of an option or stock
appreciation right, or, at the time of payment of a performance unit or at the
end of a restriction period of a restricted stock award. Supplemental cash
payments shall be subject to such terms and conditions as shall be provided by
the Committee at the time of grant, provided that in no event shall the amount
of each payment exceed:


                                       -9-

<PAGE>   13



                  (a) In the case of an option, the excess of the fair market
         value of a Share on the date of exercise over the option price
         multiplied by the number of Shares for which such option is exercised,
         or

                  (b) In the case of a stock appreciation right, performance
         unit or restricted stock award, the value of the Shares and other
         consideration issued in payment of such award.

         14. GENERAL RESTRICTIONS. Each award under the Plan shall be subject to
the requirement that, if at any time the Committee shall determine that (i) the
listing, registration or qualification of the Shares subject or related thereto
upon any securities exchange or under any state or federal law, or (ii) the
consent or approval of any government regulatory body, or (iii) an agreement by
the recipient of an award with respect to the disposition of Shares, is
necessary or desirable as a condition of, or in connection with, the granting of
such award or the issue or purchase of Shares thereunder, such award may not be
consummated in whole or in part unless such listing, registration,
qualification, consent, approval or agreement shall have been effected or
obtained, free of any conditions not acceptable to the Committee.

         15. RIGHTS OF A SHAREHOLDER. The recipient of any award under the Plan,
unless otherwise provided by the Plan, shall have no rights as a shareholder
with respect thereto unless and until certificates for Shares are issued to him.

         16. RIGHT TO TERMINATE EMPLOYMENT. Nothing in the Plan or in any
agreement entered into pursuant to the Plan shall confer upon any participant
the right to continue in employment or affect any right which his employer may
have to terminate the employment of such participant.

         17. WITHHOLDING. Whenever the Company proposes or is required to issue
or transfer Shares to a participant under the Plan, the Company shall have the
right to require the participant to remit to the Company an amount sufficient to
satisfy all federal, state and local withholding tax requirements prior to the
delivery of any certificate or certificates for such Shares. If such
certificates have been delivered prior to the time a withholding obligation
arises, the Company shall have the right to require the participant to remit to
the Company an amount sufficient to satisfy all federal, state or local
withholding tax requirements at the time such obligation arises and to withhold
from other amounts payable to the participant, as compensation or otherwise, as
necessary. Whenever payments under the Plan are to be made to a participant in
cash, such payment shall be net of any amount sufficient to satisfy all federal,
state and local withholding tax requirements. In lieu of requiring a participant
to make a payment to the Company in an amount related to the withholding tax
requirement, the Committee may, in its discretion, provide that at the
participant's election, the tax withholding obligation shall be satisfied by the
Company's withholding a portion of the Shares otherwise distributable to the
participant, such Shares being valued at the fair market value at the date of
exercise, or by the participant's delivering to the Company a portion of the
Shares previously delivered by the Company, such Shares being valued at their
fair market value as of the date of delivery of such Shares by the participant
to the Company. For this purpose, the amount of required withholding shall be a
specified rate not less than the statutory minimum federal,

                                      -10-

<PAGE>   14



state and local (if any) withholding rate, and not greater than the maximum
federal, state and local (if any) marginal tax rate applicable to the
participant and to the particular transaction. Notwithstanding any provision of
the Plan to the contrary, a participant's election pursuant to the preceding
sentences (a) must be made on or prior to the date as of which income is
realized by the recipient in connection with the particular transaction, and (b)
must be irrevocable. In lieu of a separate election on each effective date of
each transaction, a participant may file a blanket election with the Committee
which shall govern all future transactions until revoked by the participant.

         18. NON-ASSIGNABILITY. No award under the Plan shall be assignable or
transferable by the recipient thereof except by will or by the laws of descent
and distribution or except as set forth in subsection 8(d). During the life of
the recipient, such award shall be exercisable only by such person or by such
person's guardian or legal representative.

         19. NON-UNIFORM DETERMINATIONS. The Committee's determinations under
the Plan (including, without limitation determinations of the persons to receive
awards, the form, amount and timing of such awards, the terms and provisions of
such awards and the agreements evidencing same, and the establishment of values
and performance targets) need not be uniform and may be made by it selectively
among persons who receive, or are eligible to receive, awards under the Plan,
whether or not such persons are similarly situated.

         20. ADJUSTMENTS. (i) Appropriate adjustments in the aggregate number of
Shares issuable pursuant to the Plan, the number of Shares subject to each
outstanding award granted under the Plan, the option price with respect to
options and connected stock appreciation rights, the specified price of stock
appreciation rights not connected to options, and the value for Units, shall be
made to give effect to any increase or decrease in the number of issued Shares
resulting from a subdivision or consolidation of Shares, whether through
recapitalization, stock split, reverse stock split, spin-off, spin-out or other
distribution of assets to stockholders, stock distributions or combinations of
Shares, payment of stock dividends, other increase or decrease in the number of
such Shares outstanding effected without receipt of consideration by the
Company, or any other occurrence for which the Committee determines an
adjustment is appropriate.

         (ii) In the event of any merger, consolidation or reorganization of the
Company with any other corporation or corporations, or an acquisition by the
Company of the stock or assets of any other corporation or corporations, there
shall be substituted on an equitable basis, as determined by the Committee in
its sole discretion, for each Share then subject to the Plan, and for each Share
then subject to an award granted under the Plan, the number and kind of shares
of stock, other securities, cash or other property to which the holders of
Shares of the Company are entitled pursuant to such transaction.

         (iii) Without limiting the generality of the foregoing provisions of
this paragraph, any such adjustment shall be deemed to have prevented any
dilution or enlargement of a participant's rights, if such participant receives
in any such adjustment, rights that are substantially similar (after taking into
account the fact that the participant has not paid the applicable option price)
to the rights the

                                      -11-

<PAGE>   15


participant would have received had he exercised his outstanding award and
become a shareholder of the Company immediately prior to the event giving rise
to such adjustment. Adjustments under this paragraph shall be made by the
Committee, whose decision as to the amount and timing of any such adjustment
shall be conclusive and binding on all persons.

         21. AMENDMENT OR TERMINATION. The Board or the Committee may at any
time terminate, suspend or amend the Plan without the authorization of
stockholders to the extent allowed by law, including without limitation any
rules issued by the Securities and Exchange Commission under Section 16 of the
1934 Act, insofar as shareholder approval thereof is required in order for the
Plan to continue to satisfy the requirements of Rule 16b-3 under the 1934 Act.
No termination, suspension or amendment of the Plan shall adversely affect any
right acquired by any participant under an award granted before the date of such
termination, suspension or amendment, unless such participant shall consent; but
it shall be conclusively presumed that any adjustment for changes in
capitalization as provided for herein does not adversely affect any such right.
Any member of the Board who is an officer or employee of the Company shall be
without a vote on any proposed amendment to the Plan, or on any other matter
which might affect that member's individual interest under the Plan.

         22. EFFECT ON OTHER PLANS. Unless otherwise specifically provided,
participation in the Plan shall not preclude an employee's eligibility to
participate in any other benefit or incentive plan and any awards made pursuant
to the Plan shall not be considered as compensation in determining the benefits
provided under any other plan.

         23. DURATION OF THE PLAN. The Plan shall remain in effect until all
awards under the Plan have been satisfied by the issuance of Shares or the
payment of cash, but no award shall be granted more than ten years after the
date the Plan is approved by the shareholders, which shall be its effective date
of adoption.

                             NIPSCO INDUSTRIES, INC
                         1994 LONG-TERM INCENTIVE PLAN

               (AS AMENDED AND RESTATED EFFECTIVE APRIL 14, 1999)


         WHEREAS, NIPSCO Industries, Inc. (the "Company") adopted the NIPSCO
         Industries, Inc. 1994 Long-Term Incentive Plan effective April 13,
         1994, as last amended and restated effective February 1, 1998 ("Plan");
         and

         WHEREAS, pursuant to Section 18 of the Plan, the Company wishes to
         further amend the Plan in certain respects and restate it in a single
         document;

         NOW THEREFORE, the Plan is hereby amended and restated, effective April
         14, 1999, as follows:

1.  PURPOSE. The purpose of the NIPSCO Industries, Inc. 1994 Long-Term
Incentive Plan (the "Plan") is to further the earnings of NIPSCO Industries,
Inc. (the "Company") and its subsidiaries. The Plan provides long-term
incentives to those officers and key executives who make substantial
contributions by their ability, loyalty, industry and invention. The Company
intends that the Plan will thereby facilitate securing, retaining, and
motivating management employees of high caliber and potential.

2. ADMINISTRATION. The Plan shall be administered by the Nominating and
Compensation Committee ("Committee") of the Board of Directors of the Company
("Board"). The Committee shall be composed of not fewer than two members of the
Board who are "nonemployee directors" of the Company within the meaning of Rule
16b-3 under the Securities Exchange Act of 1934, as amended ("1934 Act"), and
"outside directors" of the Company within the meaning of Section 162(m) of the
Internal Revenue Code of 1986, as amended, ("Code"), and the regulations
thereunder. Subject to the express provisions of the Plan, the Committee may
interpret the Plan, prescribe, amend and rescind rules and regulations relating
to it, determine the terms and provisions of awards to officers and other key
executive employees under the Plan (which need not be identical), and make such
other determinations as it deems necessary or advisable for the administration
of the Plan. The decisions of the Committee under the Plan shall be conclusive
and binding. No member of the Board or of the Committee shall be liable for any
action taken, or determination made, hereunder in good faith. Service on the
Committee shall constitute service as a director of the Company so that members
of the Committee shall be entitled to indemnification and reimbursement as
directors of the Company, pursuant to its by-laws.

3. COMMON SHARES SUBJECT TO THE PLAN. (a) Subject to the provisions of Section
3(b), the shares that may be issued, or may be the measure of stock appreciation
rights granted, under the Plan shall not exceed in the aggregate 2,500,000
(5,000,000 after January 30, 1998) of the common shares without par value of the
Company (the "Common Shares"). Such shares may be authorized and






                                       -1-
<PAGE>   5

unissued shares or treasury shares. Except as otherwise provided herein, any
shares subject to an option or right which for any reason expires or is
terminated, unexercised as to such shares, shall again be available under the
Plan.

(b) (i) Appropriate adjustments in the aggregate number of Common Shares
issuable pursuant to the Plan, the number of Common Shares subject to each
outstanding award granted under the Plan, the option price with respect to
options and connected stock appreciation rights, the specified price of stock
appreciation rights not connected to options, and the value for Units, shall be
made to give effect to any increase or decrease in the number of issued Common
Shares resulting from a subdivision or consolidation of shares, whether through
recapitalization, stock split, reverse stock split, spin-off, spin-out or other
distribution of assets to stockholders, stock distributions or combinations of
shares, payment of stock dividends, other increase or decrease in the number of
such Common Shares outstanding effected without receipt of consideration by the
Company, or any other occurrence for which the Committee determines an
adjustment is appropriate.

     (ii) In the event of any merger, consolidation or reorganization of the
Company with any other corporation or corporations, or an acquisition by the
Company of the stock or assets of any other corporation or corporations, there
shall be substituted on an equitable basis, as determined by the Committee in
its sole discretion, for each Common Share then subject to the Plan, and for
each Common Share then subject to an award granted under the Plan, the number
and kind of shares of stock, other securities, cash or other property to which
the holders of Common Shares of the Company are entitled pursuant to such
transaction.

     (iii) Without limiting the generality of the foregoing provisions of this
paragraph, any such adjustment shall be deemed to have prevented any dilution or
enlargement of a participant's rights, if such participant receives in any such
adjustment, rights that are substantially similar (after taking into account the
fact that the participant has not paid the applicable option price) to the
rights the participant would have received had he exercised his outstanding
award and become a shareholder of the Company immediately prior to the event
giving rise to such adjustment. Adjustments under this paragraph shall be made
by the Committee, whose decision as to the amount and timing of any such
adjustment shall be conclusive and binding on all persons.

4. PARTICIPANTS. Persons eligible to participate shall be limited to those
officers and other key executive employees of the Company and its subsidiaries
who are in positions in which their decisions, actions and counsel significantly
impact upon profitability. Directors who are not otherwise officers or employees
shall not be eligible to participate in the Plan.

5. AWARDS UNDER THE PLAN. Awards under the Plan may be in the form of stock
options (both options designed to satisfy statutory requirements necessary to
receive favorable tax treatment pursuant to any present or future legislation
and options not designed to so qualify), incentive stock options, stock
appreciation rights, performance units, and restricted shares or such
combinations of the above as the Committee may in its discretion deem
appropriate.

6. SECTION 162(M) LIMITATIONS. Subject to Section 3(b) of the Plan, the maximum
number of stock options and stock appreciation rights granted to any person who
qualifies as an executive officer named from time to time in the summary
compensation table in the Company's annual meeting proxy statement and who is
employed by the Company on the last day of the taxable year (the "SCT
Executives") shall be 25,000 (50,000 after January 30, 1998) options and stock
appreciation rights with respect to Common Shares per year and 250,000 (500,000
after January 30, 1998) options and stock appreciation rights with respect to
Common Shares during the term of the Plan. The maximum number of performance
units granted to any SCT Executive shall be 25,000 (50,000 after January 30,
1998) units per year, provided that no more than 25,000 (50,000 after January
30, 1998) units may be awarded in any three year period and that the maximum
number of units granted to any SCT Executive during the term of the Plan shall
be 75,000 (150,000 after January 30, 1998). The maximum number of restricted
stock awards granted to any SCT Executive shall be 25,000 (50,000 after January
30, 1998) Common Shares per year, provided that no more than 25,000 (50,000
after January 30, 1998) Shares of restricted stock may be awarded in any
three-year period and that the maximum number of Shares of restricted stock
granted to any SCT Executive during the term of the Plan shall be 75,000
(150,000 after January 30, 1998).

7. NON QUALIFIED STOCK OPTIONS. Options shall be evidenced by stock option
agreements in such form and not inconsistent with the Plan as the Committee
shall approve from time to time, which agreements shall contain in substance the
following terms and conditions:

         (A) OPTION PRICE. The purchase price per Common Share deliverable upon
the exercise of an option shall not be less than 100% of the fair market value
of a Common Share on the day the option is granted, as determined by the
Committee. Fair market value of Common Shares for purposes of the Plan shall be
the average of the high and low prices on the New York Stock Exchange Composite
Transactions on the date of the grant, or on any other applicable date.

         (B) EXERCISE OF OPTION. Each stock option agreement shall state the
period or periods of time within which the option may be exercised by the
optionee, in whole or in part, which shall be such period or periods of time as
may be determined by the Committee, provided that the option exercise period
shall not commence earlier than six months after the date of the grant of the
option nor end later than ten years after the date of the grant of the option.
The Committee shall have the power to permit in its discretion an acceleration
of the previously determined exercise terms, within the terms of the Plan, under
such circumstances and upon such terms and conditions as it deems appropriate.

         (C) PAYMENT FOR SHARES. Except as otherwise provided in the Plan or in
any stock option agreement, the optionee shall pay the purchase price of the
Common Shares upon the exercise of any option (i) in cash, (ii) in cash received
from a broker-dealer to whom the optionee has submitted an exercise notice
consisting of a fully endorsed option (however in the case of an optionee
subject to Section 16 of the 1934 Act, this payment option shall only be
available to the extent such payment procedures comply with Regulation T issued
by the Federal Reserve Board), (iii) by delivering Common Shares having an
aggregate fair market value on the date of exercise equal to the option



                                      -3-

exercise price, (iv) by directing the Company to withhold such number of Common
Shares otherwise issuable upon exercise of such option having an aggregate fair
market value on the date of exercise equal to the option exercise price, (v) by
such other medium of payment as the Committee, in its discretion, shall
authorize at the time of grant, or (vi) by any combination of (i), (ii), (iii),
(iv) and (v). In the case of an election pursuant to (i) or (ii) above, cash
shall mean cash or check issued by a federally insured bank or savings and loan
association, and made payable to NIPSCO Industries, Inc. In the case of payment
pursuant to (ii), (iii) or (iv) above, the optionee's election must be made on
or prior to the date of exercise and shall be irrevocable. In lieu of a separate
election governing each exercise of an option, an optionee may file a blanket
election with the Committee which shall govern all future exercises of options
until revoked by the optionee. The Company shall issue, in the name of the
optionee, stock certificates representing the total number of Common Shares
issuable pursuant to the exercise of any option as soon as reasonably
practicable after such exercise, provided that any Common Shares purchased by an
optionee through a broker-dealer pursuant to clause (ii) above, shall be
delivered to such broker-dealer in accordance with 12 C.F.R.ss. 220.3(e)(4), or
other applicable provision of law.

         (D) TRANSFERABILITY. Each stock option agreement shall provide that the
option subject thereto is not transferable by the optionee otherwise than by
will or the laws of descent or distribution. Notwithstanding the preceding
sentence, an optionee, at any time prior to his death, may assign all or any
portion of the option to (i) his spouse or lineal descendant, (ii) the trustee
of a trust for the primary benefit of his spouse or lineal descendant, or (iii)
a tax-exempt organization as described in Section 501(c)(3) of the Code. In such
event the spouse, lineal descendant, trustee or tax-exempt organization will be
entitled to all of the rights of the optionee with respect to the assigned
portion of such option, and such portion of the option will continue to be
subject to all of the terms, conditions and restrictions applicable to the
option as set forth herein, and in the related stock option agreement,
immediately prior to the effective date of the assignment. Any such assignment
will be permitted only if (i) the optionee does not receive any consideration
therefor, and (ii) the assignment is expressly approved by the Committee or its
delegate. Any such assignment shall be evidenced by an appropriate written
document executed by the optionee, and a copy thereof shall be delivered to the
Committee or its delegate on or prior to the effective date of the assignment.
This paragraph shall apply to all nonqualified stock options granted under the
Plan at any time.

         (E) RIGHTS UPON TERMINATION OF EMPLOYMENT. In the event that an
optionee ceases to be an employee for any reason other than death, disability or
retirement, the optionee shall have the right to exercise the option during its
term within a period of thirty days after such termination to the extent that
the option was exercisable at the date of such termination of employment, or
during such other period and subject to such terms as may be determined by the
Committee. In the event that an optionee dies, retires, or becomes disabled
prior to termination of his option without having fully exercised his option,
the optionee or his successor shall have the right to exercise the option during
its term within a period of three years after the date of such termination due
to death, disability or retirement, to the extent that the option was
exercisable at the date of termination due to death, disability or retirement,
or during such other period and subject to such terms as may be determined by
the Committee. For purposes of the Plan, the term "disability" shall mean
disability as defined




                                      -4-
<PAGE>   8



in the Company's Long-Term Disability Plan. The Committee, in its sole
discretion, shall determine the date of any disability. For purposes of the
Plan, the term "retirement" shall mean retirement as defined in the Company's
pension plan.

8. INCENTIVE STOCK OPTIONS. Incentive stock options shall be evidenced by stock
option agreements in such form and not inconsistent with the Plan as the
Committee shall approve from time to time, which agreements shall contain in
substance the following terms and conditions:

         (A) OPTION PRICE. Except as otherwise provided in Section 8(b), the
purchase price per share of stock deliverable upon the exercise of an incentive
stock option shall not be less than 100% of the fair market value of the Common
Shares on the day the option is granted, as determined by the Committee.

         (B) EXERCISE OF OPTION. Each stock option agreement shall state the
period or periods of time within which the option may be exercised by the
optionee, in whole or in part, which shall be such period or periods of time as
may be determined by the Committee, provided that the option period shall not
commence earlier than six months after the date of the grant of the option nor
end later than ten years after the date of the grant of the option. The
aggregate fair market value (determined with respect to each incentive stock
option at the time of grant) of the Common Shares with respect to which
incentive stock options are exercisable for the first time by an individual
during any calendar year (under all incentive stock option plans of the Company
and its parent and subsidiary corporations) shall not exceed $100,000. If the
aggregate fair market value (determined at the time of grant) of the Common
Shares subject to an option, which first becomes exercisable in any calendar
year exceeds the limitation of this Section 8(b), so much of the option that
does not exceed the applicable dollar limit shall be an incentive stock option
and the remainder shall be a nonqualified stock option; but in all other
respects, the original option agreement shall remain in full force and effect.
As used in this Section 8, the words "parent" and "subsidiary" shall have the
meanings given to them in Section 424(e) and 424(f) of the Code. Notwithstanding
anything herein to the contrary, if an incentive stock option is granted to an
individual who owns stock possessing more than ten percent (10%) of the total
combined voting power of all classes of stock of the Company or of its parent or
subsidiary corporations, within the meaning of Section 422(b)(6) of the Code,
(i) the purchase price of each Common Share subject to the incentive stock
option shall be not less than one hundred ten percent (110%) of the fair market
value of the Common Shares on the date the incentive stock option is granted,
and (ii) the incentive stock option shall expire, and all rights to purchase
Common Shares thereunder shall cease, no later than the fifth anniversary of the
date the incentive stock option was granted.

         (C) PAYMENT FOR SHARES. Except as otherwise provided in the Plan or in
any stock option agreement, the optionee shall pay the purchase price of the
Common Shares upon the exercise of any option, (i) in cash, (ii) in cash
received from a broker-dealer to whom the optionee has submitted an exercise
notice consisting of a fully endorsed option (however in the case of an optionee
subject to Section 16 of the 1934 Act, this payment option shall only be
available to the extent such payment procedures comply with Regulation T issued
by the Federal Reserve Board), (iii) by delivering






                                       -5-
<PAGE>   9


Common Shares having an aggregate fair market value on the date of exercise
equal to the option exercise price, (iv) by directing the Company to withhold
such number of Common Shares otherwise issuable upon exercise of such option
having an aggregate fair market value on the date of exercise equal to the
option exercise price, (v) by such other medium of payment as the Committee, in
its discretion, shall authorize at the time of grant, or (vi) by any combination
of (i), (ii), (iii), (iv) and (v). In the case of an election pursuant to (i) or
(ii), cash shall mean cash or check issued by a federally insured bank or
savings and loan association, and made payable to NIPSCO Industries, Inc. In the
case of payment pursuant to (ii), (iii) or (iv) above, the optionee's election
must be made on or prior to the date of exercise and shall be irrevocable. In
lieu of a separate election governing each exercise of an option, an optionee
may file a blanket election with the Committee which shall govern all future
exercises of options until revoked by the optionee. The Company shall issue, in
the name of the optionee, stock certificates representing the total number of
Common Shares issuable pursuant to the exercise of any option as soon as
reasonably practicable after such exercise, provided that any Common Shares
purchased by an optionee through a broker-dealer pursuant to clause (ii) above,
shall be delivered to such broker-dealer in accordance with 12 C.F.R. ss.
220.3(e)(4), or other applicable provision of law.

         (D) TRANSFERABILITY.  Each stock option agreement shall provide
that it is not transferable by the optionee otherwise by will or the laws of
descent or distribution.

         (E) RIGHTS UPON TERMINATION OF EMPLOYMENT. In the event that an
optionee ceases to be an employee for any reason other than death, disability or
retirement, the optionee shall have the right to exercise the option during its
term within a period of thirty days after such termination to the extent that
the option was exercisable at the date of such termination of employment, or
during such other period and subject to such terms as may be determined by the
Committee. In the event that an optionee dies, retires, or becomes disabled
prior to termination of his option without having fully exercised his option,
the optionee or his successor shall have the right to exercise the option during
its term within a period of three years after the date of such termination due
to death, disability or retirement, to the extent that the option was
exercisable at the date of termination due to death, disability or retirement,
or during such other period and subject to such terms as may be determined by
the Committee. Notwithstanding the foregoing, in accordance with Section 422 of
the Code, if an incentive stock option is exercised more than ninety days after
termination of employment, that portion of the option exercised after such date
shall automatically be a nonqualified stock option, but in all other respects,
the original option agreement shall remain in full force and effect.

The provisions of this Section 8 shall be construed and applied, and (subject to
the limitations of section 20) shall be amended from time to time so as to
comply with Section 422 or its successors of the Code and regulations issued
thereunder.

9. STOCK APPRECIATION RIGHTS. Stock appreciation rights shall be evidenced by
stock appreciation right agreements in such form and not inconsistent with the
Plan as the Committee shall approve from time to time, which agreements shall
contain in substance the following terms and conditions:




                                       -6-
<PAGE>   10



         (A) AWARDS. A stock appreciation right shall entitle the grantee to
receive upon exercise the excess of (i) the fair market value of a specified
number of shares of the Company Common Shares at the time of exercise over (ii)
a specified price which shall not be less than 100% of the fair market value of
the Common Shares at the time the stock appreciation right was granted, or, if
connected with a previously issued stock option, not less than 100% of the fair
market value of Common Shares at the time such option was granted. A stock
appreciation right may be granted in connection with all of any portion of a
previously or contemporaneously granted stock option or not in connection with a
stock option.

         (B) TERM. Stock appreciation rights shall be granted for a period of
not less than one year nor more than ten years, and shall be exercisable in
whole or in part, at such time or times and subject to such other terms and
conditions, as shall be prescribed by the Committee at the time of grant,
subject to the following:

                 (i) No stock appreciation right shall be exercisable in whole
            or in part, during the six-month period starting with the date of
            grant; and

                 (ii) Stock appreciation rights will be exercisable only during
         a grantee's employment, except that in the discretion of the Committee
         a stock appreciation right may be made exercisable for up to thirty
         days after the grantee's employment is terminated for any reason other
         than death, disability or retirement. ln the event that a grantee dies,
         retires, or becomes disabled without having fully exercised his stock
         appreciation rights, the grantee or his successor shall have the right
         to exercise the stock appreciation rights during their term within a
         period of three years after the date of such termination due to death,
         disability or retirement to the extent that the right was exercisable
         at the date of such termination or during such other period and subject
         to such terms as may be determined by the Committee.

         The Committee shall have the power to permit in its discretion an
         acceleration of previously determined exercise terms, within the terms
         of the Plan, under such circumstances and upon such terms and
         conditions as it deems appropriate.

         (C) PAYMENT. Upon exercise of a stock appreciation right, payment shall
be made in cash, in the form of Common Shares at fair market value, or in a
combination thereof, as the Committee may determine.

10. PERFORMANCE UNITS. Performance Units ("Units") shall be evidenced by
performance unit agreements in such form and not inconsistent with the Plan as
the Committee shall approve from time to time, which agreements shall contain in
substance the following terms and conditions:

         (A) PERFORMANCE PERIOD. At the time of award, the Committee shall
establish with respect to each Unit award a performance period of not less than
two, nor more than five, years.




                                      -7-
<PAGE>   11



         (B) VALUATION OF UNITS. At the time of award, the Committee shall
establish with respect to each such award a value for each Unit which shall not
thereafter change, or which may vary thereafter determinable from criteria
specified by the Committee at the time of award.

         (C) PERFORMANCE TARGETS. At the time of award, the Committee shall
establish maximum and minimum performance targets to be achieved with respect to
each award during the performance period. The participant shall be entitled to
payment with respect to all Units awarded if the maximum target is achieved
during the performance period, but shall be entitled to payment with respect to
a portion of the Units awarded according to the level of achievement of
performance targets, as specified by the Committee, for performance during the
performance period which meets or exceeds the minimum target but fails to meet
the maximum target.

         The performance targets established by the Committee shall relate to
corporate, division, or unit performance and may be established in terms of (i)
changes in stock price, gross revenue, pre-tax operating income, or earnings per
share; or (ii) ratios of stock price, earnings, or pre-tax operating income
relative to shareholder's equity, earnings, total assets, or to assets employed;
or (iii) a comparison of any of the preceding measures to similar measures for
competitors. Multiple targets may be used and may have the same or different
weighting, and they may relate to absolute performance or relative performance
as measured against other institutions or divisions or units thereof.

         (D)     ADJUSTMENTS.  At any time prior to payment of the Units, the
Committee may adjust previously established performance targets and other terms
and conditions, including the corporation's, or division's or unit's financial
performance for Plan purposes, to reflect major unforeseen events such as
changes in laws, regulations or accounting practices, mergers, acquisitions or
divestitures or extraordinary, unusual or non-recurring items or events.

         (E)     PAYMENTS OF UNITS.  Following the conclusion of each
performance period, the Committee shall determine the extent to which
performance targets have been attained for such period as well as the other
terms and conditions established by the Committee. The Committee shall determine
what, if any, payment is due on the Units. Payment shall be made in cash, in the
form of Common Shares at fair market value, or in a combination thereof, as the
Committee may determine.

         (F)     TERMINATION OF EMPLOYMENT.  In the event that a participant
holding a Unit award ceases to be an employee prior to the end of the applicable
performance period by reason of death, disability or retirement, his Units, to
the extent earned under the applicable performance targets, shall be payable at
the end of the performance period in proportion to the active service of the
participant during the performance period, as determined by the Committee. Upon
any other termination of employment, participation shall terminate forthwith and
all outstanding Units held by the participant shall be canceled.

         (G)     OTHER TERMS.  The Unit agreements shall contain such other
terms and provisions and conditions not inconsistent with the Plan as shall be
determined by the Committee.

11.  RESTRICTED STOCK AWARDS.  Restricted Stock Awards under the Plan shall be
in the form of Common Shares of the Company, restricted as to transfer and
subject to forfeiture, and shall be evidenced by restricted stock agreements in
such form and not inconsistent with the Plan as the Committee shall approve from
time to time, which agreements shall contain in substance the following terms
and conditions:

         (A)     RESTRICTION PERIOD.  Restricted Common Shares awarded pursuant
         to the Plan shall be subject to such terms, conditions, and
         restrictions, including without limitation: prohibitions against
         transfer, substantial risks of forfeiture, attainment of performance
         objectives and repurchase by the Company or right of first refusal, and
         for such period or periods as shall be determined by the Committee at
         the time of grant. The Committee shall have the power to permit in its
         discretion, an acceleration of the expiration of the applicable
         restriction period with respect to any part or all of the Common Shares
         awarded to a participant.

         The performance objectives established by the Committee shall relate to
         corporate, division or unit performance, and may be established in
         terms of (i) changes in stock price, gross revenue, pre-tax operating
         income, or earnings per share; or (ii) ratios of stock price, earnings,
         or pre-tax operating income relative to shareholder's equity, earnings,
         total assets, or to assets employed; or (iii) a comparison of any of
         the preceding measures to similar measures for competitors. Multiple
         objectives may be used and may have the same or different weighting,
         and they may relate to absolute performance or relative performance as
         measured against other institutions or divisions or units thereof.

         (B)     RESTRICTIONS UPON TRANSFER.  Common Shares awarded, and the
         right to vote such Shares and to receive dividends thereon, may not be
         sold, assigned, transferred, exchanged, pledged, hypothecated, or
         otherwise encumbered, except as herein provided, during the restriction
         period applicable to such Shares. Subject to the foregoing, and except
         as otherwise provided in the Plan, the participant shall have all the
         other rights of a shareholder including, but not limited to, the right
         to receive dividends and the right to vote such Shares.



         (C)     CERTIFICATES.  Each certificate issued in respect of Common
         Shares awarded to a participant shall be deposited with the Company, or
         its designee, and shall bear the following legend:

                 "This certificate and the shares represented hereby are subject
         to the terms and conditions (including forfeiture and restrictions
         against transfer) contained in the NIPSCO Industries, Inc. 1994
         Long-Term incentive Plan and an Agreement entered into by the
         registered owner. Release from such terms and conditions shall obtain
         only in accordance with the provisions of the Plan and Agreement, a
         copy of each of which is on file in the office of the Secretary of said
         Company."



                                      -9-
<PAGE>   13



         (D)     LAPSE OF RESTRICTIONS.  A restricted stock agreement shall
         specify the terms and conditions upon which any restrictions upon
         Common Shares awarded under the Plan shall lapse, as determined by the
         Committee. Upon the lapse of such restrictions, Common Shares, free of
         the foregoing restrictive legend, shall be issued to the participant or
         his legal representative.

         (E)     TERMINATION PRIOR TO LAPSE OF RESTRICTIONS.  In the event of a
         participant's termination of employment, other than due to death,
         disability or retirement, prior to the lapse of restrictions applicable
         to any Common Shares awarded to such participant, all Shares as to
         which there still remains unlapsed restrictions shall be forfeited by
         such participant without payment of any consideration to the
         participant, and neither the participant nor any successors, heirs,
         assigns, or personal representatives of such participant shall
         thereafter have any further rights or interest in such Shares or
         certificates.

12.  SUPPLEMENTAL CASH PAYMENTS. Subject to the Company's discretion, stock
option, incentive stock option, stock appreciation right, performance unit or
restricted stock agreements may provide for the payment of a supplemental cash
payment to a participant promptly after the exercise of an option or stock
appreciation right, or, at the time of payment of a performance unit or at the
end of a restriction period of a restricted stock award. Supplemental cash
payments shall be subject to such terms and conditions as shall be provided by
the Committee at the time of grant, provided that in no event shall the amount
of each payment exceed:

         (a)     In the case of an option, the excess of the fair market value
         of a Common Share on the date of exercise over the option price
         multiplied by the number of Common Shares for which such option is
         exercised, or

         (b)     In the case of a stock appreciation right, performance unit or
         restricted stock award, the value of the Common Shares and other
         consideration issued in payment of such award.

13.  GENERAL RESTRICTIONS. Each award under the Plan shall be subject to the
requirement that, if at any time the Committee shall determine that (i) the
listing, registration or qualification of the Common Shares subject or related
thereto upon any securities exchange or under any state or federal law, or (ii)
the consent or approval of any government regulatory body, or (iii) an agreement
by the recipient of an award with respect to the disposition of Common Shares,
is necessary or desirable as a condition of, or in connection with, the granting
of such award or the issue or purchase of Common Shares thereunder, such award
may not be consummated in whole or in part unless such listing, registration,
qualification, consent, approval or agreement shall have been effected or
obtained, free of any conditions not acceptable to the Committee.

14.  RIGHTS AS A SHAREHOLDER. The recipient of any award under the Plan, unless
otherwise provided by the Plan, shall have no rights as a shareholder with
respect thereto unless and until certificates for Common Shares are issued to
the recipient.



                                      -10-
<PAGE>   14


15.  EMPLOYMENT RIGHTS.  Nothing in the Plan or in any agreement entered into
pursuant to the Plan shall confer upon any participant the right to continue in
employment or affect any right which his employer may have to terminate the
employment of such participant.

16.  TAX--WITHHOLDING.  Whenever the Company proposes or is required to issue or
transfer Common Shares to a participant under the Plan, the Company shall have
the right to require the participant to remit to the Company an amount
sufficient to satisfy all federal, state and local withholding tax requirements
prior to the delivery of any certificate or certificates for such Common Shares.
If such certificates have been delivered prior to the time a withholding
obligation arises, the Company shall have the right to require the participant
to remit to the Company an amount sufficient to satisfy all federal, state or
local withholding tax requirements at the time such obligation arises and to
withhold from other amounts payable to the participant, as compensation or
otherwise, as necessary. Whenever payments under the Plan are to be made to a
participant in cash, such payment shall be net of any amount sufficient to
satisfy all federal, state and local withholding tax requirements. In lieu of
requiring a participant to make a payment to the Company in an amount related to
the withholding tax requirement, the Committee may, in its discretion, provide
that, at the participant's election, the tax withholding obligation shall be
satisfied by the Company's withholding a portion of the Common Shares otherwise
distributable to the participant, such Common Shares being valued at their fair
market value at the date of exercise, or by the participant's delivering to the
Company a portion of the Common Shares previously delivered by the Company, such
Common Shares being valued at their fair market value as of the date of delivery
of such Common Shares by the participant to the Company. For this purpose, the
amount of required withholding shall be a specified rate not less than the
statutory minimum federal, state and local (if any) withholding rate, and not
greater than the maximum federal, state and local (if any) marginal tax rate
applicable to the participant and to the particular transaction. Notwithstanding
any provision of the Plan to the contrary, a participant's election pursuant to
the preceding sentences (a) must be made on or prior to the date as of which
income is realized by the recipient in connection with the particular
transaction, and (b) must be irrevocable. In lieu of a separate election on each
effective date of each transaction, a participant may file a blanket election
with the Committee which shall govern all future transactions until revoked by
the participant.

17. CHANGE IN CONTROL. (a) Effect of Change in Control. Notwithstanding any of
the provisions of the Plan or any agreement evidencing awards granted hereunder,
upon a Change in Control of the Company (as defined in Section 17(b)) all
outstanding awards shall become fully exercisable and all restrictions thereon
shall terminate in order that participants may fully realize the benefits
thereunder. Further, the Committee, as constituted before such Change in
Control, is authorized, and has sole discretion, as to any award, either at the
time such award is granted hereunder or any time thereafter, to take any one or
more of the following actions: (i) provide for the exercise of any such award
for an amount of cash equal to the difference between the exercise price and the
then fair market value of the Common Shares covered thereby had such award been
currently exercisable; (ii) provide for the vesting or termination of the
restrictions on any such award; (iii) make such adjustment to any such award
then outstanding as the Committee deems appropriate to reflect such





                                      -11-
<PAGE>   15



Change in Control; and (iv) cause any such award then outstanding to be assumed,
by the acquiring or surviving corporation, after such Change in Control.

         (b)     Definition of Change in Control. A "Change in Control" of the
     Company shall be deemed to have occurred if any one of the occurrences of a
     "Change in Control" set forth in the Change in Control and Termination
     Agreements between the Company and certain executive officers thereof shall
     have been satisfied.

18.  AMENDMENT OR TERMINATION.  The Board or the Committee may at any time
terminate, suspend or amend the Plan without the authorization of shareholders
to the extent allowed by law, including without limitation any rules issued by
the Securities and Exchange Commission under Section 16 of the 1934 Act, insofar
as shareholder approval thereof is required in order for the Plan to continue to
satisfy the requirements of Rule 16b-3 under the 1934 Act. No termination,
suspension or amendment of the Plan shall adversely affect any right acquired by
any participant under an award granted before the date of such termination,
suspension or amendment, unless such participant shall consent; but it shall be
conclusively presumed that any adjustment for changes in capitalization as
provided for herein does not adversely affect any such right. Subject to the
preceding sentence, the Plan as amended and restated effective April 14, 1999
shall apply to all awards at any time granted hereunder.

19.  EFFECT ON OTHER PLANS.  Unless otherwise specifically provided,

opinion of the Committee, unable to manage properly his or her affairs, then
such payments shall be paid in one of the following ways, as the Committee
deems advisable: (i) to such person directly; or (ii) to the legally appointed
guardian or conservator of such person for his or her exclusive benefit; or

         shall in any way obligate: (i) the Company to nominate a Nonemployee
         Director for reelection or to continue to retain a Nonemployee
         Director; or (ii) a Nonemployee Director to agree to be nominated for
         reelection or to continue to serve on the Board.

         Company, and the heirs, executors, administrators, and assigns of each
         Eligible Nonemployee Director.

         the state of Indiana.

                  NIPSCO INDUSTRIES, INC. NONEMPLOYEE DIRECTOR
                           RESTRICTED STOCK UNIT PLAN

1.   Purpose
     -------

     NIPSCO Industries, Inc. (the "Corporation") has adopted the NIPSCO
Industries, Inc. Nonemployee Director Restricted Stock Unit Plan (the "Plan"),
effective as of January 1, 1999.

     The purpose of the Plan is to provide deferred compensation to nonemployee
directors of the Corporation ("Nonemployee Directors"). Such deferred
compensation shall be based upon the award of Restricted Stock Units, the value
of which is related to the value, and the appreciation in the value, of the
common stock of the Corporation (the "Common Stock"). The Plan is also intended
to benefit the Corporation by enhancing the interest of Nonemployee Directors in
the growth and success of the Corporation.

2.   Administration
     --------------

     The Plan shall be administered by the Nominating and Compensation Committee
(the "Committee") of the Board of Directors of the Corporation (the "Board") .
Subject to the provisions of the Plan, Nonemployee Directors shall be granted
Restricted Stock Units under the Plan.

     The Committee shall have authority to interpret the Plan, to adopt and
revise rules and regulations relating to the Plan, to determine the conditions
subject to which any Restricted Stock Units may be granted or payable, and to
make any other determinations which it believes necessary or advisable for the
administration of the Plan. Determinations by the Committee shall be made by
majority vote and shall be final and binding on all parties with respect to all
matters relating to the Plan.

3.   Grants
     ------

     Each Nonemployee Director on the Board on April 14, 1999 shall receive a
grant of 500 Restricted Stock Units on such date. Each Nonemployee Director who
is subsequently elected or reelected as a member of the Board shall receive a
grant of 500 Restricted Stock Units upon the date of each such election or
reelection. In no event however, will any grant be made hereunder to a
Nonemployee Director after December 31, 2002.

     The maximum number of Restricted Stock Units that may be awarded under the
Plan shall not exceed an aggregate of 25,000. If any Restricted Stock Units
awarded under the Plan shall be forfeited or canceled, such Restricted Stock
Units may again be awarded under the Plan. Restricted Stock Units shall be
subject to such terms and conditions, in addition to the terms and conditions
set forth in the Plan, as the Committee shall determine.



<PAGE>   2

4.   Restricted Stock Units
     ----------------------

     Restricted Stock Units granted to a Nonemployee Director shall be credited
to a Restricted Stock Unit Account (the "Account") established and maintained
for such Nonemployee Director. The Account of a Nonemployee Director shall be
the record of Restricted Stock Units granted to him under the Plan, is solely
for accounting purposes and shall not require a segregation of any assets of the
Corporation. Each Restricted Stock Unit shall be valued by the Committee, in the
manner provided in Section 8, as of the date of grant thereof. Each grant of
Restricted Stock Units under the Plan to a Nonemployee Director and the value of
such Restricted Stock Units as of the date of grant shall be communicated by the
Committee in writing to the Nonemployee Director within thirty (30) days after
the date of grant.

5.   Dividends on Restricted Stock Units
     -----------------------------------

     Additional Restricted Stock Units shall be credited to each Nonemployee
Director's Account with respect to Restricted Stock Units included in such
Account from time to time, to reflect dividends paid to stockholders of the
Corporation with respect to the Common Stock. These additional Restricted Stock
Units shall be granted at such time or times and shall be subject to such terms
and conditions, in addition to the terms and conditions set forth in the Plan,
as the Committee shall determine.

6.   Maturity of Restricted Stock Units
     ----------------------------------

     (a)  Restricted Stock Units granted to a Nonemployee Director shall mature
according to the following schedule:

          Anniversary of Grant                         Percentage of
               Date                                    Matured Units

               First                                        20%
               Second                                       40%
               Third                                        60%
               Fourth                                       80%
               Fifth                                       100%

     (b)  Notwithstanding the provisions of paragraph (a) next above, all
Restricted Stock Units granted to a Nonemployee Director shall become fully
matured upon the Nonemployee Director's termination of service on the Board due
to death, disability or a Change in Control of the Corporation. For purposes of
this Section, a Nonemployee Director will be considered disabled if, in the
determination of the Committee, he is subject to a physical or mental condition
which is expected to render the Nonemployee Director unable to perform his usual
duties or any comparable duties as a member of the Board. For purposes of this
Section, a Change in Control of the Corporation shall be deemed to have occurred
if any one of the occurrences of "Change in Control"


                                        2

<PAGE>   3

set forth in the Change in Control and Termination Agreements between the
Corporation and certain executive officers thereof shall have been satisfied.

7.   Payment for Restricted Stock Units
     ----------------------------------

     (a)  Upon a Nonemployee Director's termination of service on the Board for
any reason other than for Cause (as defined herein), the Nonemployee Director
shall be entitled to receive from the Corporation an amount, with respect to
each then mature Restricted Stock Unit in the Nonemployee Director's Account,
equal to the then Fair Market Value (as determined by the Committee pursuant to
Section 8) of each such mature Restricted Stock Unit.

     (b)  Payment to a Nonemployee Director of the amount set forth in paragraph
(a) next above for Restricted Stock Units shall be made in cash in a lump sum.
Payment will be made within sixty (60) days after the date of termination of the
Nonemployee Director's service on the Board. A Nonemployee Director will not be
entitled to receive any earnings on the value of his Restricted Stock Units with
respect to the period between his termination of service on the Board and the
receipt of payment under the Plan.

     (c)  Notwithstanding any other provision of the Plan, all rights to any
payment hereunder to a Nonemployee Director with respect to any mature or
unmatured Restricted Stock Units will be discontinued and forfeited, and the
Corporation will have no further obligation hereunder to such Nonemployee
Director or any other person, if the Nonemployee Director is discharged from
service on the Board for Cause. For purposes of the Plan, "Cause" shall mean:

          (1)  the Nonemployee Director's conviction of any criminal violation
               involving dishonesty, fraud or breach of trust;

          (2)  the Nonemployee Director's willful engagement in any misconduct
               in the performance of his duty that materially injures the
               Corporation;

          (3)  the Nonemployee Director's performance of any act which, if known
               to the customers or stockholders of the Corporation, would
               materially and adversely impact on the business of the
               Corporation; or

          (4)  the Nonemployee Director's willful and substantial nonperformance
               of assigned duties.

     The Committee shall have sole discretion with respect to the application of
the provisions of this paragraph (c) and such exercise of discretion shall be
conclusive and binding upon the Nonemployee Director, and all other persons.

8.   Valuation of Restricted Stock Units
     -----------------------------------

     (a)  For all purposes of the Plan, the value of a Restricted Stock Unit on
a date of grant pursuant to Section 4, or upon termination of service on the
Board pursuant to Section 7, will be equal to the then Fair Market Value of a
share of Common Stock.

     (b)  For purposes of the Plan, Fair Market Value shall mean the average of
the highest and lowest quoted selling prices for shares of Common Stock on the
relevant date, or (if there were no sales on such date) the weighted average of
the mean between the highest and lowest quoted selling prices on the nearest day
before the nearest day after the relevant date, as reported in The Wall Street
Journal or a similar publication selected by the Board.

9.   Forfeiture of Restricted Stock Units
     ------------------------------------

     If the Nonemployee Director's service on the Board is terminated for any
reason other than death, disability or a Change in Control of the Corporation,
such Nonemployee Director's rights with respect to Restricted Stock Units in his
Account which have not matured on or prior to the date of the occurrence of such
event will terminate and be forfeited and neither the Nonemployee Director nor
his heirs, personal representatives, successors or assigns shall have any future
rights with respect to any such Restricted Stock Units.

10.  Changes in Capital and Corporate Structure
     ------------------------------------------

     Appropriate adjustments in the aggregate number of Restricted Stock Units
issuable pursuant to the Plan, the number of outstanding Restricted Stock Units,
and the value of such Restricted Stock Units, shall be made to give effect to
any increase or decrease in the number of issued shares of Common Stock
resulting from a subdivision or consolidation of shares, whether through
recapitalization, stock split, reverse stock split, spinoff, spinout or other
distribution of assets to stockholders, stock distributions or combination of
shares, payment of stock dividends, other increase or decrease in the number of
shares of Common Stock outstanding effected without receipt or consideration by
the Corporation, or any other occurrence for which the Committee determines an
adjustment is appropriate. Adjustments made under this Section shall be made by
the Committee, whose decision as to the nature and timing of any such
adjustments shall be conclusive and binding on all persons.

11.  Nontransferability
     ------------------

     Restricted Stock Units granted under the Plan, and any rights and
privileges pertaining thereto, may not be transferred, assigned, pledged or
hypothecated in any manner, by operation of law or otherwise, other than by will
or by the laws of descent and distribution, and shall not be subject to
execution, attachment or similar process. In the event of a Nonemployee
Director's death, payment of any amount due under the Plan shall be made to the
duly appointed and qualified executor or other personal representative of the
Nonemployee Director's estate to be distributed in


                                        4

<PAGE>   5

accordance with the Nonemployee Director's will or applicable intestacy law; or
in the event that there shall be no such representative duly appointed and
qualified within six (6) months after the date of death of such deceased
Nonemployee Director, then to such persons as, at the date of his death, would
be entitled to share in the distribution of such deceased Nonemployee Director's
personal estate under the provisions of the applicable statute then in force
governing the descent of intestate property, in the proportions specified in
such statute.

12.  Voting and Stock Ownership
     --------------------------

     Except as set forth in Section 5 above, no Nonemployee Director shall be
entitled to any voting rights or stock ownership rights with respect to Common
Stock attributable to Restricted Stock Units granted under the Plan.

13.  Miscellaneous Provisions
     ------------------------

     (a)  No Nonemployee Director or other person shall have any claim or right
to be granted Restricted Stock Units under the Plan except as set forth in the
Plan. Neither the Plan nor any action taken hereunder shall be construed as
giving any Nonemployee Director any right to be retained on the Board.

     (b)  The Plan shall at all times be entirely unfunded and no provision
shall at any time be made with respect to segregating assets of the Corporation
for payment of any benefits hereunder. No Nonemployee Director or other person
shall have any interest in any particular assets of the Corporation by reason of
the right to receive a benefit under the Plan and any such Nonemployee Director
or other person shall have only the rights of a general unsecured creditor of
the Corporation with respect to any rights under the Plan.

     (c)  Except when otherwise required by the context, any masculine
terminology in this document shall include the feminine, and any singular
terminology shall include the plural.

14.  Amendment of the Plan
     ---------------------

     The Committee may alter or amend the Plan from time to time without
obtaining the approval of the Board or the stockholders of the Corporation. No
amendment to the Plan may alter, impair or reduce the number of Restricted Stock
Units granted under the Plan prior to the effective date of such amendment, or
adversely affect the terms of such Restricted Stock Units, without the written
consent of any affected Nonemployee Director.

15.  Termination of the Plan
     -----------------------

     The Committee may at any time terminate the Plan without obtaining approval
of the Board or the stockholders of the Corporation, and unless sooner

the date of termination in accordance with the terms of the Plan.

          on the Board after attaining the age of seventy (70) years, or a
          Change in Control of the Corporation, then each Nonemployee Director's
          rights with respect to Restricted Stock Units which have not matured
          on or prior to the date of the occurrence of such event will terminate
          and be forfeited and neither the Nonemployee Director nor his heirs,
          personal representatives, successors or assigns shall have any future
          rights with respect to any such Restricted Stock Units.

     This First Amendment to the Plan has been executed by a duly authorized
officer of the Corporation.

                     SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN

               AS AMENDED AND RESTATED EFFECTIVE SEPTEMBER 1, 1994


                                    ARTICLE I

                                     Purpose

     Effective as of December 23, 1982, and as subsequently amended as of
January 1, 1989, Northern Indiana Public Service Company adopted the Northern
Indiana Public Service Company Supplemental Executive Retirement Plan. Effective
as of January 1, 1991, NIPSCO Industries, Inc. (the "Company") adopted the
NIPSCO Industries, Inc. Supplemental Executive Retirement Plan (the "Plan"), to
benefit the Company by providing key executives and employees with additional
security in order to aid the Company in retaining its present management and,
should circumstances require it, to aid the Company in attracting additions to
management. The Company, by providing such additional benefits, expects key
executives and employees to be available for consulting assignments to the
Company after retirement, at the Company's request. The Plan was amended and
restated, effective January 1, 1993 in order to clarify certain provisions. The
Plan is being further amended and restated effective September 1, 1994.

     It is intended that the Plan be exempt from the reporting and disclosure
requirements of Title 1 of the Employee Retirement Income Security Act of 1974
because it is an unfunded plan maintained by an employer for the purpose of
providing benefits for a select group of management or highly compensated
employees.

          Participant's Service to a maximum of 30 years; plus

          Participant's Service in excess of 20 years, to a maximum of 30 years;

     (3)  less 5% of the Participant's Primary Social Security Benefit,
          multiplied by the Participant's Service to a maximum of 20 years.

     Supplemental Retirement Pension in a reduced amount (as described in
     Section 4.2 below).

     prior to Normal Retirement, but after Early Retirement, shall be eligible
     for a monthly Supplemental Retirement Pension in an amount determined in

     percent (6%) for each of the first two (2) years and four percent (4%) for
     each of the next five (5) years that commencement of the Participant's

     would attain age 62 years; or (ii) if the Participant had completed 25
     years of Service at the time of his termination, by six percent (6%) for
     the first year and four percent (4%) for each of the next four (4) years

4.3  Termination of Employment Prior to Early Retirement: Upon termination of
     employment prior to Early Retirement, a Participant shall be eligible for a
     monthly Supplemental Retirement Pension, calculated on a single-life basis
     equal to the excess, if any, of the pension the Participant would be
     eligible to receive under the NIPSCO Pension Plan, if the limitations
     required by Code Sections 401(a)(17) and 415, the limitation on bonuses to
     50% of base pay and the potential limitations relating to Taxable
     Compensation were not applied, over the pension the Participant is eligible
     to receive under the NIPSCO Pension Plan, and commencing on the same date
     as the pension under the NIPSCO Pension Plan.

4.4  Supplemental Disability Pension: If a Participant becomes disabled (as
     determined by the Committee) while in the active employment of the Company
     prior to age 65, the Participant shall be eligible for a monthly
     Supplemental Disability Pension to age 65, calculated on a single-life
     basis, and equal to the larger of (a) or (b) below, reduced in each case by

               by the Participant's Service to a maximum of 30 years, plus


                                       -4-

<PAGE>   6



          (2)  0.6% of the Participant's Final Average Compensation multiplied
               by the Participant's Service in excess of 30 years.

     b.   The sum of:

          (1)  3% of the Participant's Final Average Compensation multiplied by
               the Participant's Service to a maximum of 20 years; plus

          (2)  0.5% of the Participant's Final Average Compensation multiplied
               by the Participant's Service in excess of 20 years, to a maximum
               of 30 years;

          (3)  less 5% of the Participant's Primary Social Security Benefit,
               multiplied by the Participant's Service to a maximum of 20 years.

     After age 65, the Participant shall be eligible for a monthly Supplemental
     Retirement Pension in accordance with Section 4.1, based on Service the
     Participant would have had if the Participant had continued working to age
     65, the Participant's Final Average Compensation at the time he became
     disabled, the Primary Social Security Benefit determined at the time the
     Participant became disabled, and the single-life pension the Participant is
     entitled to receive at age 65 from the NIPSCO Pension Plan, determined at
     the time he became disabled.

4.5  Supplemental Spouse Pension: Upon the death of a Participant in active
     employment, his or her spouse, if any, shall be eligible to receive a
     monthly Supplemental Spouse Pension equal to the greater of:

     a.   25% of the Participant's Final Average Compensation; or

     b.   the monthly amount that would have been payable to such surviving
          spouse if the Participant had elected payment of his monthly
          Supplemental Retirement Pension in the form of a reduced 50% joint and
          survivor pension, with his spouse as the contingent annuitant,
          terminated employment (on the date of his actual death) and then died
          immediately prior to the commencement of payments.

     The Supplemental Spouse Pension shall commence in the month next following
     the month of the Participant's death and continue for the life of such
     spouse. In the event that the Supplemental Spouse Pension calculated under
     option a. of this Section will provide a greater benefit to the spouse
     immediately following the Participant's death, but option b. of this
     Section will provide a greater monthly benefit as of the date the
     Participant would have attained age 55, the amount of monthly Supplemental
     Spouse Pension payable to the surviving spouse shall be: (1) calculated and
     payable under option a. during the period immediately following the
     Participant's death; and (2) recalculated and payable according to option
     b. beginning on the date the Participant would have attained age 55.
     Beginning on the earliest date that the surviving spouse could have begun
     receiving a benefit under the NIPSCO Pension Plan, the Supplemental Spouse
     Pension payable under this Section shall be reduced by the amount of
     benefit under the NIPSCO Pension Plan that the spouse is (or would have
     been) entitled to receive.


                                       -5-

4.6  Optional Forms of Payment: In lieu of the single-life pension described in
     Section 4.1, a Participant may elect to receive a reduced 50% joint and
     survivor pension with his or her spouse as the contingent annuitant. The
     reduction in the Participant's pension will be computed in the same manner
     as in the NIPSCO Pension Plan.

4.7  Retiree Death Benefit: Upon the death of a retired Participant, a lump-sum
     death benefit equal to 50% of his or her retiree group life insurance shall
     be paid to the retiree's beneficiary.

4.8  Cost of Living Adjustment: The benefits payable under Sections 4.1 through
     4.6 shall be increased in the same percentage and at the same time as cost
     of living adjustments are made to the pensions of salaried employees of the
     Company under the NIPSCO Pension Plan.

4.9  Small Benefit Amounts: At the discretion of the Committee, small benefits
     may be paid in quarterly, semi-annual or annual installments, or in a
     single lump sum.

                                  Miscellaneous

5.1  Plan Financing: Except as set forth below, benefits under this Plan shall
     be paid from the general assets of the Company. To the extent any
     Participant acquires a right to receive payments hereunder, such right
     shall be no greater than the right of any other unsecured creditor of the
     Company. Notwithstanding the foregoing, the Company shall enter into a
     trust agreement ("Trust Agreement") whereby the Company shall agree to
     contribute to a trust ("Trust") for the purpose of accumulating assets to
     assist the Company in fulfilling its obligations to Participants hereunder.
     Such Trust shall include the provision that all assets of the Trust shall
     be subject to the creditors of the Company in the event of insolvency.

5.2  Non-Compete and Related Provisions: Benefits under this Plan may be
     forfeited if:

     a.   A Participant, while employed by the Company or within a period of
          three (3) years after the Participant's termination of employment for
          any reason, including Retirement (the "Restrictive Period"), engages
          in activity or employment that directly or indirectly competes with
          the business of the Company, including, but not by way of limitation,
          by directly or indirectly owning, managing, operating, controlling,
          financing, or by directly or indirectly serving as an employee,
          officer or director of or consultant to, or by soliciting or inducing,
          or attempting to solicit or induce, any employee or agent of the
          Company to terminate employment with the Company, and become employed
          by, any person, firm, partnership, corporation, trust or other entity
          that provides commodities, products or services to customers of the
          Company of the same type as commodities, products or services provided
          by the Company (the "Restrictive Covenant"). The foregoing Restrictive
          Covenant shall not prohibit a Participant from owning directly or
          indirectly capital stock or similar securities


                                       -6-

          which are listed on a securities exchange or quoted on the National
          Association of Securities Dealers Automated Quotation System which do
          not represent more than one percent (1%) of the outstanding capital
          stock of any such entity; or

         b.       A Participant performs any action or makes any statement that
                  is detrimental to the Company, unless such action or statement
                  is retracted to the Company's satisfaction after the
                  Participant is notified regarding such action or statement.

5.3  Nonguarantee of Employment: Participation in the Plan does not limit the
     right of the Company to discharge any individual with or without cause.

5.4  Nonalienation of Benefits: A Participant may not assign or transfer any
     benefits under this Plan.

5.5  Plan Amendment or Termination: The Chairman of the Board of Directors may
     amend any provision of this Plan except for Article III and Article IV,
     which may only be amended by the Company. The Company may terminate the
     Plan at any time, except that any benefits that are payable due to a
     retirement, death or disability occurring prior to the amendment or
     termination shall not be reduced or discontinued. No amendment or
     termination of the Plan shall directly or indirectly deprive any current or
     former Participant (or beneficiary) of all or any portion of any
     Supplemental Retirement Benefit or surviving spouse benefit, the payment of
     which has commenced prior to the effective date of such amendment or
     termination, or which would be payable if the Participant terminated
     employment for any reason on such effective date. Upon termination of the
     Plan, distribution of Supplemental Retirement Benefits and any surviving
     spouse benefits shall be made to Participants, spouses or beneficiaries in
     the manner and at the time described in Article IV of the Plan. No
     additional Supplemental Retirement Benefits shall be earned after
     termination of the Plan, except as provided in Section 6.3.




5.6  Indemnification:

     a.   Limitation of Liability: Notwithstanding any other provision of the
          Plan or the Trust, none of the Company or any member of the Committee,
          or an individual acting as an employee or agent of any of them, shall
          be liable to any Participant or former Participant, or any beneficiary
          or eligible spouse of any Participant or former Participant, for any
          claim, loss, liability or expense incurred in connection with the Plan
          or the Trust, except when the same shall have been judicially
          determined to be due to the willful misconduct of such person.

     b.   Indemnity: The Company shall indemnify and hold harmless each member
          of the Committee, or any employee of the Company or any individual
          acting as an employee or agent of either of them (to the extent not
          indemnified or saved harmless

                                       -7-

<PAGE>   9

          under any liability insurance or any other indemnification arrangement
          with respect to the Plan or the Trust) from any and all claims,
          losses, liabilities, costs and expenses (including attorneys' fees)
          arising out of any actual or alleged act or failure to act made in
          good faith pursuant to the provisions of the Plan, including expenses
          reasonably incurred in the defense of any claim relating thereto with
          respect to the administration of the Plan or the Trust, except that no
          indemnification or defense shall be provided to any person with
          respect to any conduct that has been judicially determined, or agreed
          by the parties, to have constituted willful misconduct on the part of
          such person, or to have resulted in his receipt of personal profit or
          advantage to which he is not entitled. In connection with the
          indemnification provided by the preceding sentence, expenses incurred
          in defending a civil or criminal action, suit or proceeding, or
          incurred in connection with a civil or criminal investigation, may be
          paid by the Company in advance of the final disposition of such
          action, suit, proceeding, or investigation, as authorized by the
          Committee in the specific case, upon receipt of an undertaking by or
          on behalf of the party to be indemnified to repay such amount unless
          it shall ultimately be determined that the person is entitled to be
          indemnified by the Company pursuant to this paragraph.

     c.   Severability: Each of the Sections contained in the Plan, and each
          provision in each Section, shall be enforceable independently of every
          other Section or provision in the Plan, and the invalidity or
          unenforceability of any Section or provision shall not invalidate or
          render unenforceable any other Section or provision contained herein.
          If any Section or provision in a Section is found invalid or
          unenforceable, it is the intent of the parties that a court of
          competent jurisdiction shall reform the Section or provision to
          produce its nearest enforceable economic equivalent.

5.7  Action by Company: Any action required or permitted of the Company under
     the Plan shall be by resolution of its Board of Directors or by a duly
     authorized committee of its Board of Directors, or by a person or persons
     authorized by resolution of its Board of Directors or such committee.

          Securities Exchange Act of 1934, of capital stock of the Company
          entitled to exercise more than thirty percent (30%) of the outstanding
          voting power of all capital stock of the Company entitled to vote in
          elections of directors ("Voting Power");


                                       -8-

     b.   The effective time of (i) a merger or consolidation of the Company
          with one or more other corporations as a result of which the holders
          of the outstanding Voting Power of the Company immediately prior to
          such merger or consolidation (other than the surviving or resulting
          corporation or any Affiliate or Associate thereof) hold less than
          fifty percent (50%) of the Voting Power of the surviving or resulting
          corporation, or (ii) a transfer of thirty percent (30%) of the Voting

     c.   The election to the Board of Directors of the Company of candidates
          who were not recommended for election by the Board of Directors of the
          Company in office immediately prior to the election, if such
          candidates constitute a majority of those elected in that particular
          election.

     d.   For purposes of this Article, the term: (1) "Affiliates and
          Associates" shall have the meaning given it in Rule 12b-2 under the
          Securities Exchange Act of 1934; and (2) "Substantial Portion of the
          Property of the Company" shall mean fifty percent (50%) of the
          aggregate book value of the assets of the Company and its Affiliates
          and Associates as set forth on the most recent balance sheet of the
          Company, prepared on a consolidated basis, by its regularly employed,
          independent, certified public accountants.

     e.   Notwithstanding the foregoing, a Change in Control shall not be deemed
          to take place with respect to a Participant by virtue of any
          transaction in which the Participant is a participant in a group
          effecting an acquisition of the Company and, after such acquisition,
          the Participant holds an equity interest in the entity that has
          acquired the Company.

6.2  Potential Change in Control: A "Potential Change in Control" shall include
     any of the following:

     a.   The delivery to the Company by any "person," as defined in Section
          13(d) (3) of the Act, of a statement containing the information
          required by Schedule 13-D under the Act, or any amendment to any such
          statement, that shows that such person has acquired, directly or
          indirectly, the beneficial ownership of (i) more than twenty percent
          (20%) of any class of equity security of the Company entitled to vote
          as a class in the election or removal from office of directors, or
          (ii) more than twenty percent (20%) of the voting power of any group
          of classes of equity securities of the Company entitled to vote as a
          single class in the election or removal from office of directors.

     b.   The Company becomes aware that preliminary or definitive copies of a
          proxy statement and information statement or other information have
          been filed with the Securities and Exchange Commission pursuant to
          Rule 14a-6, Rule 14c-5, or Rule 14f-1 under the Act relating to a
          proposed change in control of the Company.


                                       -8-

<PAGE>   11


     c.   The delivery to the Company pursuant to Rule 14d-3 under the Act of a
          Tender Offer Statement relating to equity securities of the Company.

     d.   The Board of Directors of the Company adopts a resolution to the
          effect that for purposes of this Trust a Potential Change in Control
          has occurred.

6.3  Additional Service and Compensation Upon Change in Control: With respect to
     a Participant who, pursuant to contract with the Company, is entitled to
     compensation from the Company for an additional 36 months in the event
     that, within 24 months after a Change in Control, the Participant's
     employment is terminated by the Company for any reason other than Good
     Cause, or the Participant terminates employment with the Company for Good
     Reason, such Participant's years of Service under Section 2.3 and
     Supplemental Retirement Pension under Section 4.1 of the Plan shall be
     calculated as if the Participant had continued in employment with the
     Company for an additional 36 months, at the rate of Compensation in effect
     immediately prior to his employment termination; provided that, in no event
     shall the counting of a Participant's Compensation during this 36 month
     period reduce his Final Average Compensation figure below its highest level
     prior to the Participant's termination of employment.

6.4  Waiver of Service and Age Requirements Upon Change in Control: A
     Participant whose employment is terminated upon or after a Change in
     Control, but prior to Early Retirement shall be eligible for the
     Supplemental Retirement Pension specified in Section 4.1, rather than the
     Supplemental Retirement Pension specified in Section 4.3, commencing at
     Normal Retirement, except that the Participant may elect to begin receiving
     such Supplemental Retirement Pension at any time after attaining age 55
     years, subject to the reduction specified in Section 4.2.

6.5  Funding of Plan Benefits Upon Change in Control: Upon a Potential Change in
     Control, the Committee shall identify the amount by which the present value
     of all benefits earned to date under the Plan (after offsets) exceeds the
     value of the applicable Trust assets, calculated using the Pension Benefit
     Guaranty Corporation immediate annuity interest rate as of the date of the
     Potential Change in Control, the 1983 GAM mortality tables, and the most
     valuable optional payment form (the "Full Funding Amount"), and the Company
     shall contribute such Full Funding Amount to the Trust. Each Participant's
     benefits for purposes of calculating present value shall be the highest
     benefit the Participant would have under the Plan within the six (6) months
     following a Potential Change in Control, assuming that the Participant's
     employment continues for six (6) months at the same rate of Compensation,
     and that the Participant receives any benefit enhancement provided by the
     Plan, or any other agreement, upon a Change in Control.

6.6  Plan Administration and Amendment Upon a Change in Control: Upon and after
     a Change in Control, the Company no longer shall have the power to appoint
     or remove members of the Committee, nor the power to approve legal counsel
     or actuaries employed by the Committee. Upon and after a Change in Control
     only the Committee members shall have the power to appoint or remove
     members. If, at any time after a Change in Control, all


                                      -10-

<PAGE>   12

     members of the Committee have been removed or resigned, then all of the
     powers, rights and duties vested in the Committee by Article VII below
     shall be vested in the trustee of the Trust.

6.7  Committee Discretion to Pay Lump Sum After a Change in Control: Upon and
     after a Change in Control, the Committee may, in its sole discretion,
     distribute, or cause the trustee under the Trust to distribute, to a
     Participant the present value (determined in accordance with the
     assumptions in Section 6.5) of the Participant's Supplemental Retirement
     Pension, Supplemental Disability Pension, and any other benefit payable
     under this Plan, in a lump sum payment.

6.8  Definitions:

     a.   Good Cause: shall be deemed to exist if, and only if the Participant:
          (1) engages in acts or omissions constituting dishonesty, intentional
          breach of fiduciary obligation, intentional wrongdoing or malfeasance,
          in each case that results in substantial harm to the Company; or (2)
          is convicted of a criminal violation involving fraud or dishonesty.

     b.   Good Reason: shall exist if: (1) there is a significant change in the
          nature or scope of the Participant's authority or duties; (2) there is
          a significant reduction in the Participant's monthly rate of Base
          Salary or benefits; or (3) the Company changes by 100 miles or more,
          the principal location in which the Participant is required to perform
          services.


                                   ARTICLE VII


                       Plan Administration: The Committee

7.1  Committee Membership: The Company shall appoint a Committee to administer
     the Plan. A Committee member may resign at any time by giving thirty days'
     advance written notice to the Company and the other Committee members. The
     Company may remove a Committee member by giving advance written notice to
     him and the other Committee members.

7.2  General Powers, Rights and Duties: The committee has the following powers,
     rights and duties in addition to those given it elsewhere in the Plan:

     a.   To select a chairman and secretary, if it believes it advisable, who
          may, but need not, be Committee members.

     b.   To interpret the Plan and determine all questions arising in the
          administration, interpretation and application of the Plan, including,
          but not limited to the power to determine the rights or eligibility of
          employees or




                                      -11-

          Participants and their beneficiaries, and the amount of their
          respective benefits under the Plan, and to remedy ambiguities,
          inconsistencies or omissions.

     c.   To adopt such rules of procedure and regulations as in its opinion may
          be necessary for the proper and efficient administration of the Plan
          and as are consistent with the Plan.

     d.   To enforce the Plan and the rules and regulations, if any, adopted by
          the Committee as above.

     e.   To direct the trustee as respects benefit payments or other
          distributions from the Trust fund pursuant to the provisions of the
          Plan.

     f.   To furnish the Company with such information as may be required by it
          for tax or other purposes as respects the Plan.

     g.   To employ agents, attorneys, accountants, actuaries or other persons
          (who also may be employed by the Company) and to allocate or delegate
          to them such powers, rights and duties as the Committee may consider
          necessary or advisable to properly carry out the administration of the
          Plan, including maintaining the accounts of Participants, provided
          that such allocation or delegation, and the acceptance thereof by such
          agents, attorneys, accountants, actuaries or other persons, shall be
          in writing.

7.3  Manner of Action: During a period in which two or more Committee members
     are acting, the following provisions shall apply where the context admits:

     a.   A Committee member by writing may delegate any or all of his rights,
          powers, duties and discretion to any other Committee member, with the
          consent of the latter.

     b.   The Committee members may act by meeting, or by writing signed without
          meeting, and may sign any document by signing one document or concur
          rent documents.

     c.   An action or a decision of a majority of the Committee members as to a
          matter shall be as effective as if taken or made by all Committee
          members.

     d.   If, because of the number qualified to act, there is an even division
          of opinion among the Committee members as to a matter, the Company
          shall decide the matter; except that this provision shall not apply
          upon or after a Change in Control.


                                      -12-

<PAGE>   14




     e.   The certificate of the secretary of the Committee or of a majority of
          the Committee members that the Committee has taken or authorized any
          action shall be conclusive in favor of any person relying on the
          certificate.

7.4  Information Required by Committee: The Company shall furnish the Committee
     with such data and information as the Committee may deem necessary or
     desirable in order to administer the Plan. The records of the Company as to
     an employee's or Participant's period or periods of employment, termination
     of employment and the reason therefor, reemployment and Compensation will
     be conclusive on all persons unless determined to the Committee's
     satisfaction to be incorrect. Participants and other persons entitled to
     benefits under the Plan also shall furnish the committee with such
     evidence, data or information as the Committee considers necessary or
     desirable to administer the Plan.

7.5  Committee Decision Final: Subject to applicable law, and the provisions of
     Section 7.6, any interpretation of the provisions of the Plan and any
     decision on any matter within the discretion of the Committee made by the
     Committee in good faith shall be binding on all persons. To the extent not
     inconsistent with this Plan, all definitions, terms and provisions set
     forth in the NIPSCO Pension Plan, including with respect to the
     administrative powers and duties of the Committee, the expenses of
     administration, and the procedures for filing claims, also shall be
     applicable with respect to this Plan.

7.6  Claims Procedure: In the event that a Participant (or beneficiary) makes a
     claim for benefits under the Plan to the Committee and such claim is denied
     in whole or in part by the Committee, the Committee will notify the
     Participant (or beneficiary) of the denial. Such notification will be made
     in writing, within 90 days of the date the claim is received by the
     Committee. The notification will include: (i) the specific reasons for the
     denial; (ii) specific reference to the Plan provisions upon which the
     denial is based; (iii) a description of any additional information
     necessary for the claimant to perfect the claim and an explanation of why
     such material or information is necessary; and (iv) an explanation of the
     applicable review procedures.

     The Participant (or beneficiary) has 60 days from the date he receives
     notice of a claim denial to file a written request for review of the denial
     with the Committee. The Committee will review the claim denial and inform
     the Participant (or beneficiary) in writing of its decision within 60 days
     of the date the claim review request is received by the Committee. This
     decision will be final.

1999 FINANCIAL REVIEW

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
================================================================================

- --------------------------------------------------------------------------------
                                HOLDING COMPANY
- --------------------------------------------------------------------------------

NiSource Inc. (NiSource), formerly NIPSCO Industries, Inc., is an energy and
utility-based holding company headquartered in Merrillville, Indiana, that
provides natural gas, electricity and water to the public for residential,
commercial and industrial uses. NiSource was organized as an Indiana holding
company in 1987 under the name "NIPSCO Industries, Inc.," and changed its name
to NiSource Inc. on April 14, 1999, to reflect its new direction as a
multi-state supplier of energy and water resources and related services.

NiSource's gas business is comprised primarily of regulated gas utilities that
operate throughout northern Indiana and New England. In addition, NiSource
expanded its gas marketing, trading and storage operations with the April 1999
acquisition of TPC Corporation, now renamed EnergyUSA-TPC Corp. (TPC).
NiSource's electric business is comprised of a regulated electric utility that
operates in northern Indiana. The electric business also includes wholesale
sales and power trading activities. NiSource's regulated gas and electric
subsidiaries are collectively referred to as the "Energy Utilities." NiSource's
regulated water subsidiaries are collectively called the "Water Utilities."
Collectively the Energy and Water Utilities are referred to as the "Utilities."

     Non-regulated energy and utility-related products and services are provided
through the "Products and Services" subsidiaries. Products and Services
subsidiaries perform energy-related services and offer products in connection
with these services, which include pipeline construction, repair and maintenance
of underground gas pipelines and locating and marking utility lines.

     In addition to the Utilities and the Products and Services subsidiaries,
NiSource has a wholly-owned subsidiary, NiSource Capital Markets, Inc. (Capital
Markets), which engages in financing activities for NiSource and certain of its
subsidiaries, excluding Northern Indiana Public Service Company (Northern
Indiana).

- --------------------------------------------------------------------------------
                                   NET INCOME
- --------------------------------------------------------------------------------

     Net income decreased $33.5 million from 1998 to $160.4 million for 1999.
The 1999 and 1998 twelve month periods are not directly comparable due to the
acquisition of Bay State Gas Company (BSG) in February 1999 and TPC in April
1999. As natural gas businesses, BSG and TPC record the bulk of their revenues
during the winter heating season. The timing of these acquisitions, the seasonal
nature of these operations and a milder-than-normal winter and fall resulted in
lower earnings for the year.

     Excluding the results of operations of the BSG and TPC, 1999 earnings
reflected stronger operating results from NiSource's electric and water
businesses along with continued customer growth. Results include after-tax
charges of $8.1 million incurred in connection with the company's attempted
acquisition of Columbia Energy Group (CEG). NiSource also recorded after-tax
adjustments of $21.7 million during 1999. These adjustments were the result of
adverse economic conditions which impacted equity investments, the most
significant of which was in oil and gas development, and the decision to abandon
a number of non-core businesses and facilities.

     For 1998, net income increased $3.1 million from 1997 to $193.9 million due
primarily to an increase in electric utility margin resulting from a warmer 1998
summer as compared to 1997 and a full year of results of operations relating to
the Water Utilities, offset partially by a weak performance in electric
wholesale operations.

                                  GAS REVENUES
- --------------------------------------------------------------------------------

The gas revenues described herein represent the combined revenues of our gas
utilities and gas marketing segments adjusted for intercompany transactions. Gas
revenues were $1.7 billion in 1999, an increase of $443.7 million from 1998.
This increase was primarily due to the inclusion of $316.4 million gas revenues
from BSG, increased gas marketing and trading revenues as a result of the TPC
acquisition in April 1999 and increased gas sales to residential customers as a
result of colder weather during 1999, partially offset by decreased gas sales to
commercial and industrial customers. During 1999, gas deliveries in dekatherms
(dth), which include transportation services and BSG, increased 31%. Gas
deliveries to residential and commercial customers increased reflecting the
acquisition of BSG and heating degree-days 12% higher than 1998. The Energy
Utilities had 1,071,221 gas customers at December 31, 1999.

     Gas revenues were $1.2 billion in 1998, an increase of $25.2 million from
1997. This increase is attributable to increased gas marketing activity
partially offset by decreased deliveries to residential and commercial customers
due to significantly warmer weather than 1997, decreased gas costs per dth and
decreased gas transition costs. During 1998, gas deliveries in dth, which
include transportation services, increased 6% due to increased gas marketing
activities, partially offset by gas deliveries to residential and commercial
customers which decreased 20% and 23%, respectively, reflecting heating
degree-days 21% lower than 1997.

to utilize transportation services provided by the Energy Utilities. Gas
transportation customers purchase much of their gas directly from producers and
marketers and then pay a transportation fee to have their gas delivered over the
Energy Utilities' systems. The Energy Utilities transported 252.5, 202.9, and
200.9 million dth for others in 1999, 1998 and 1997, respectively. The basic
steel industry accounted for 15% of natural gas delivered (including volumes
transported) during 1999.

     The components of the changes in gas revenues are shown in the following

                               GAS COSTS OF SALES
- --------------------------------------------------------------------------------

The gas costs described herein represent the combined costs of our gas utilities
and gas marketing segments adjusted for intercompany transactions. The gas costs
increased $262.4 million (28%) in 1999 due to the inclusion of gas costs of
$155.2 million for BSG, increased gas marketing and trading activities and
increased purchased gas costs per dth for the Energy Utilities. The average cost
for the Energy Utilities' purchased gas in 1999, after adjustment for gas
transition costs billed to transport customers, was $2.67 per dth excluding
purchased gas costs of BSG as compared to $2.60 per dth in 1998. Gas costs
increased $67.9 million (8%) in 1998 mainly due to increased purchases of gas of
$198 million related to gas marketing activities partially offset by decreased
gas purchases, decreased gas transition costs and decreased gas costs per dth by
the Energy Utilities. The average cost for the Energy Utilities' purchased gas
in 1998, after adjustment for gas transition costs billed to transport
customers, was $2.60 per dth as compared to $3.15 per dth in 1997.

- --------------------------------------------------------------------------------
                             GAS OPERATING MARGINS
- --------------------------------------------------------------------------------

Gas operating margin increased $181.3 million in 1999. This increase mainly
reflects $161.2 million of gas operating margin from BSG and increased
deliveries to residential and commercial customers reflecting colder weather
during 1999, partially offset by decreased deliveries to industrial customers.
Gas operating margin decreased $42.7 million in 1998 due to decreased deliveries
to residential and commercial customers reflecting the warmer heating season in
1998 than 1997, partially offset by increased deliveries of gas transported for
others.

- --------------------------------------------------------------------------------
                               ELECTRIC REVENUES
- --------------------------------------------------------------------------------

In 1999, electric revenues were $1.1 billion (after elimination of intercompany
transactions of approximately $3.0 million), a decrease of $305.6 million from
1998. Sales of electricity in kilowatt-hours (kwh) decreased 38% from 1998.
Electric revenues decreased as a result of significantly reduced non-regulated
wholesale sales and power marketing transactions, partially offset by increased
electric sales to residential and commercial customers due to warmer weather
during the third quarter of 1999, and increased industrial sales. Sales to
residential and commercial customers increased 2% and 4% in kwh, respectively,
reflecting the warmer summer in 1999. At December 31, 1999, NiSource had 425,833
electric customers.

     In 1998, electric revenues were $1.4 billion, an increase of $242.0 million
from 1997. Sales of electricity in kwh increased 25.5% from 1997. The increase
in elec-


                                       25
<PAGE>   3
tric revenue was primarily due to increased sales to residential and
commercial customers (increases of 7% and 6% in kwh, respectively), reflecting a
significantly warmer summer in 1998 and increased wholesale sales and power
marketing activities. The increases were partially offset by a 2% kwh reduction
in sales to industrial customers, reflecting a full year of operations at two
cogeneration projects located at major industrial customers' facilities. The
basic steel industry accounted for 29% of electric sales during 1999.

     The components of the changes in electric revenues are shown in the
following table:

- --------------------------------------------------------------------------------
                             ELECTRIC COST OF SALES
- --------------------------------------------------------------------------------

Cost of fuel for electric generation in 1999 decreased $1.5 million compared to
1998 primarily due to decreased fuel costs per kwh generated. The average cost
per kwh generated decreased 3% from 1998 to 1.47 cents per kwh in 1999. Cost of
fuel for electric generation in 1998 increased mainly as a result of increased
production of 8%. The average cost per kwh generated decreased 3% from 1997 to
1.52 cents per kwh in 1998.

- --------------------------------------------------------------------------------
                                POWER PURCHASED
- --------------------------------------------------------------------------------

Power Purchased decreased $340.5 million in 1999 as a result of decreased
wholesale sales and power marketing activities. Power purchased increased $208.5
million in 1998 as a result of increased bulk power purchases and increased
wholesale power marketing activities.

- --------------------------------------------------------------------------------
                           ELECTRIC OPERATING MARGINS
- --------------------------------------------------------------------------------

Operating margin from electric sales in 1999 increased $36.5 million. This
increase occurred mainly due to improved margins on wholesale sales and power
trading transactions and increased sales to residential and commercial customers
as a result of warmer weather in the third quarter of 1999. Operating margin
from electric sales in 1998 increased $21.4 million due to increased sales to
residential and commercial customers, reflecting a significantly warmer summer
in 1998 than in 1997, and increased wholesale sales, partially offset by
decreased sales to industrial customers.

- --------------------------------------------------------------------------------
                                 WATER REVENUE
- --------------------------------------------------------------------------------

Water revenues in 1999 were $98.4 million (after elimination of intercompany
transactions of approximately $0.1 million), of which water sales to residential
and commercial customers accounted for $88.2 million. The $14.4 million increase
was primarily due to increased water volumes sold and increased water rates for
Indianapolis Water Company (IWC) that became effective on April 8, 1998 and
April 8, 1999. The Water Utilities had sales of 45,424 in millions of gallons
(m.g.)

and served 275,688 customers at December 31, 1999. Water revenues for 1998 were
$84.0 million. Water sales to residential and commercial customers accounted for
$75.2 million of 1998 revenues. The Water Utilities had sales of 40,822 m.g. and
served 253,664 customers at December 31, 1998. Water revenues for the period
April 1997 through December 1997 were $60.7 million, of which water sales to
residential and commercial customers accounted for $54.4 million. March 1997 was
the month during which NiSource acquired the Water Utilities. The Water
Utilities had sales of 32,504 m.g. during the last nine months of 1997 and
served 246,643 customers at December 31, 1997.

     The components of the changes in water revenues are shown in the following

                            WATER OPERATING MARGINS
- --------------------------------------------------------------------------------

The Water Utilities' operating margin in 1999 increased $14.4 million. This
increase was primarily due to increased water volumes sold and increased water
rates for IWC that became effective on April 8, 1998 and April 8, 1999. The
Water Utilities' operating margin in 1998 increased $23.2 million reflecting the
inclusion in the NiSource consolidated financial statements of a full year of
the Water Utilities' operating results in 1998. The Water Utilities contributed
$60.7 million to operating margin in 1997, reflecting the March 1997 acquisition
of the Water Utilities.

- --------------------------------------------------------------------------------
                         PRODUCTS AND SERVICES REVENUE
- --------------------------------------------------------------------------------

In 1999, Products and Services revenues were $271.7 million (after elimination
of intercompany transactions of approximately $12 million), an increase of $59.3
million from 1998. This increase reflects revenues from a new cogeneration
project which began commercial operations in August 1998, increased pipeline
construction activity, increased line locating and marking activity and the
inclusion of revenue of BSG's unregulated subsidiaries commencing in February
1999. In 1998, Products and Services revenues were $212.4 million, an increase
of $55.8 million from 1997. This increase reflected increased pipeline
construction activity and line locating and marking activities in the amount of
$31.7 million reflecting a full year of operations included in 1998 (the
pipeline construction and line locating businesses were acquired in March 1997)
and a new cogeneration project which began commercial operations in August 1998.

     The components of the changes in operating revenues at Products and
Services are shown in the following table:

================================================================================

The cost of sales in 1998 for Products and Services increased $28.3 million
mainly due to inclusion of the cost of sales for the pipeline construction and
line locating and marking subsidiaries (acquired in March 1997) for twelve
months in 1998 compared to nine months in 1997.

- --------------------------------------------------------------------------------
                      PRODUCTS AND SERVICES COST OF SALES

Products and Services operating margin increased $21.0 million during 1999,
reflecting a new energy-related project, which began commercial operations in
August 1998 and increased pipeline construction activity and the inclusion of
the operating margin of BSG's unregulated subsidiaries in February 1999.
Products and Services operating margin in 1998 increased $27.6 million
reflecting the inclusion of a full year of operations of pipeline construction
activity and line locating and marking activities and a new cogeneration project
which began commercial operations in August 1998.

- --------------------------------------------------------------------------------
                  OPERATING EXPENSES AND TAXES (EXCEPT INCOME)
- --------------------------------------------------------------------------------

Operating expenses and taxes (except income) increased $213.1 million from 1998,
of which $127.3 million is due to the acquisition of BSG in February 1999.
Operating expenses and taxes (except income) increased $18.5 million in 1998
from 1997.

    The operating and maintenance expenses of the Energy Utilities increased
$89.1 million from 1998. The increase was primarily due to the inclusion of
$79.1 million of operating expenses of BSG commencing in February 1999,
increased operating costs of $7.4 million, increased employee related costs of
$15.6 million and increased expenses for distributed generation and fuel cell
research and development which were partially offset by a $13 million insurance
settlement related to manufactured gas plants site cleanup costs. The
unregulated gas and electric businesses operation expenses increased $10.4
million primarily due to the inclusion of $6.1 million of TPC operation costs
from April to December 1999. Operating and maintenance expenses at the Energy
Utilities decreased $22.7 million 1998 from 1997 mainly due to decreased
employee related costs of $11.7 million, decreased sales and marketing
activities of $5.7 million and decreased electric production operating costs of
$4.3 million.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS (Continued)
================================================================================

Operating expenses at the Water Utilities increased $5.8 million from 1998 due
to increased water treatment and employee related costs. Operation expenses at
the Water Utilities increased $12.2 million from 1997 reflecting the inclusion
of a full year of operation of the Water Utilities.

     Operating expenses for Products and Services increased $14 million in 1999
reflecting the inclusion of operating expense of BSG's unregulated subsidiaries
in February 1999, and a full year of operating costs for a new cogeneration
facility which began commercial operation during 1998. Operating expenses for
Products and Services increased $22.6 million in 1998 from 1997 reflecting a
full year of operations for pipeline construction and line locating activities
acquired in March 1997 and the startup of operations of a new cogeneration
facility during 1998.

     Operating expenses also include charges of $13.1 million for professional
fees and filing costs incurred during 1999 in connection with the attempted
acquisition of CEG.

     Depreciation and amortization expenses increased $54.9 million in 1999 from
1998, primarily resulting from inclusion of depreciation and amortization for
BSG ($36.2 million) and increased depreciation expense at the Energy and Water
Utilities due to plant additions. Depreciation and amortization expense
increased $6.7 million in 1998 from 1997 as a result of plant additions and the
inclusion of twelve months of depreciation and amortization expenses for the
Water Utilities and its unregulated subsidiaries, including the pipeline
construction business and the line locating and marking business.

     Taxes (except income) increased $15.4 million in 1999 primarily as the
result of the BSG acquisition ($12.0 million).

- --------------------------------------------------------------------------------
                             INTEREST EXPENSE, NET
- --------------------------------------------------------------------------------

     Interest expense, net increased $37.8 million and $8.2 million in 1999 and
1998, respectively. The 1999 increase reflects the inclusion of interest charges
for BSG of $19 million, interest on the September 1999 issuance of $160 million
in Puttable Reset Securities (PURS) and increased interest expense on higher
short-term borrowings. The 1998 increase reflects twelve months of interest
payments on $300 million of Capital Markets' medium-term notes and $75 million
of Capital Markets' Junior Subordinated Deferrable Interest Debentures, Series A
and the inclusion of twelve months of interest expense at IWC Resources
Corporation (IWCR), which was acquired in March 1997.

Income Taxes decreased $10.4 million in 1999. This decrease ~is primarily a
result of decreased income before income taxes. Income taxes decreased $5.3
million in 1998. This decrease is primarily as a result of a decrease in income
before income taxes and a lower effective income tax rate.

                        LIQUIDITY AND CAPITAL RESOURCES
- --------------------------------------------------------------------------------

Generally, cash flow from operations has provided sufficient liquidity to meet
current operating requirements. Because the utility and utility construction
business is seasonal in nature, commercial paper is issued for short-term
financing. As of December 31, 1999 and December 31, 1998, $299.6 million and
$193.7 million of commercial paper was outstanding, respectively. The weighted
average interest rate on commercial paper outstanding as of December 31, 1999
was 6.29%.

     NiSource and its subsidiaries may borrow under two five-year, $100 million
revolving credit agreements that terminate on September 23, 2003 and two 364-day
$100 million revolving credit agreements that terminate on September 23, 2000.
The 364-day agreements may be extended at expiration for additional periods of
364 days. Under these agreements, funds are borrowed at a floating rate of
interest or, under certain circumstances, at a fixed rate of interest for
short-term periods. These agreements provide financing flexibility and may be
used to support the issuance of commercial paper. At December 31, 1999 and 1998,
there were no borrowings outstanding under these agreements.

     In addition, various NiSource subsidiaries maintain lines of credit for up
to an aggregate of $199.9 million with lenders at either the lender's commercial
prime or market lending rates. As of December 31, 1999, there were $54.1 million
of borrowings outstanding under these lines of credit with a weighted average
interest rate of 6.06%. As of December 31, 1998, there were $84.1 million of
borrowings outstanding under these lines of credit.

     NiSource and its subsidiaries maintain money market lines of credit for up
to $394.4 million. As of December 31, 1999, there were $156.2 million
outstanding under these money market lines of credit at a weighted average
interest rate of 6.78%. At December 31, 1998, there were $127.3 million of
borrowings outstanding under these money market lines of credit.

     Forty million dollars in revenue bonds were issued in July 1998 and $80.0
million in medium-term notes were issued in February 1999. The revenue bonds,
which were used to redeem previously existing revenue bonds, bear interest at
5.95% per annum and mature on July 15, 2028. The medium-term notes, which were
used in part to reduce existing credit facilities, consist of $35.0 million in
ten-year notes that bear interest at 5.99% interest per annum and $45.0 million
in twenty-year notes that bear interest at 6.61% per annum.

     In February 1999 an underwritten public offering of Corporate Premium
Income Equity Securities (Corporate PIES) was completed. The net proceeds of
approximately $334.7 million were primarily used to refinance the short-term
borrowings incurred to pay the cash portion of the acquisition cost of BSG, and
repay other short-term indebtedness. In September 1999, Capital Markets issued
$160 million of PURS in an underwritten public offering and the underwriters
acquired a call option to purchase the PURS on September 28, 2000. The net
proceeds from the sale of the PURS of $162.4 million were also used to refinance
short-term indebtedness incurred in connection with the acquisition of BSG in
February 1999. See "Short-Term Borrowings" in the Notes to the Consolidated
Financial Statements for a description of the Corporate PIES and the PURS.

     In June 1999, NiSource commenced a tender offer to acquire CEG. In December
1999, CEG acknowledged preliminary indications of interest from numerous other
third parties and invited formal bids from those companies that had indicated a
preliminary value higher than the NiSource tender offer price of $74 per share.
As a result, in December, NiSource wrote off the costs associated with its
tender offer. On February 11, 2000, the NiSource tender offer expired.

     On February 28, 2000, after completion of the bidding process initiated by
CEG, NiSource and CEG announced approval of a merger agreement under which
NiSource will form a new holding company, which will acquire all of the
outstanding shares of CEG valued at approximately $6 billion. The new holding
company will also assume approximately $2.5 billion of CEG debt. Under the
agreement, CEG shareholders have the option to receive new holding company stock
for up to 30% of the outstanding CEG shares. Under the common stock option, each
CEG share will be exchanged for $74 in new holding company stock, based on the
average NiSource share price prior to the closing, but not more than 4.4848
shares of new holding company stock for each CEG share. Under the cash option,
each CEG share will be exchanged for $70 in cash plus a $2.60 face value unit
(consisting of a zero coupon debt security with a forward equity contract). A
commitment letter was accepted under which certain financial institutions
agreed, under specified conditions, to provide up to $6.0 billion to finance the
acquisition of CEG. The merger is conditioned upon, among other things, the
approvals of the shareholders of both companies and various regulatory
commissions. If NiSource shareholder approval is not obtained, the merger
agreement provides that the transaction will automatically be restructured to
eliminate the 30% common stock option for CEG shareholders.

     Utility construction expenditures for 1999, 1998 and 1997 were
approximately $341 million, $245 million and $219 million, respectively.
NiSource's total utility plant investment on December 31, 1999 was $8.2 billion.
During recent years, NiSource has been able to finance its construction program
with internally generated funds and expects to be able to meet future
commitments through such funds.

     The Energy Utilities do not anticipate the need to file for retail gas or
electric base rate increases in the near future. IWC has agreed to a moratorium
on water rate increases until 2002.

     On January 27, 2000, the Citizens Action Coalition

(CAC), a private consumer organization, filed a petition before the Indiana
Utility Regulatory Commission (IURC). The petition does not seek a specified
amount of rate reduction, but rather alleges that the existing Northern Indiana
electric rates are "unreasonable and unsafe," and seeks to have the IURC force
Northern Indiana to produce detailed financial calculations that would justify
its electric rates. Northern Indiana intends to oppose the petition on both
legal and factual grounds, and believes that its current rates are just and
reasonable as required by statute.

      During 1999, NiSource's non-utility subsidiaries acquired interests in
other properties and investments totalling approximately $44 milion.


- --------------------------------------------------------------------------------
                MARKET RISK SENSITIVE INSTRUMENTS AND POSITIONS
- --------------------------------------------------------------------------------

Risk Management

Risk is an inherent part of NiSource's energy businesses and activities. The
extent to which NiSource properly and effectively identifies, assesses, monitors
and manages each of the various types of risk involved in its businesses is
critical to its profitability. NiSource seeks to identify, assess, monitor and
manage, in accordance with defined policies and procedures, the following
principal risks involved in NiSource's energy businesses: commodity market risk,
interest rate risk, credit risk and foreign currency risk. Risk management at
NiSource is a multi-faceted process with independent oversight that requires
constant communication, judgment and knowledge of specialized products and
markets. NiSource's senior management takes an active role in the risk
management process and has developed policies and procedures that require
specific administrative and business functions to assist in the identification,
assessment and control of various risks. In recognition of the increasingly
varied and complex nature of the energy business, NiSource's risk management
policies and procedures are evolving and subject to ongoing review and
modification.

      NiSource is exposed to risk through various daily business activities,
including specific trading risks and non-trading risks. The non-trading risks to
which NiSource is exposed include interest rate risk, foreign currency risk and
commodity price risk of its Energy Utilities and certain gas marketing
activities. The market risk resulting from trading activities consists primarily
of commodity price risk. NiSource's risk management policy permits the use of
certain financial instruments to manage its market risk, including futures,
forwards, options and swaps. Risk management at NiSource is defined as the
process by which the organization ensures that the risks to which it is exposed
are the risks to which it desires to be exposed to achieve its primary business
objectives. NiSource employs various analytic techniques to measure and monitor
its market risks, including value-at-risk (VaR) and instrument sensitivity to
market factors. VaR represents the potential loss for an instrument or portfolio
from adverse changes in market factors, for a specified time period and at a
specified confidence level.

Trading Risks

COMMODITY MARKET RISK. Market risk refers to the risk that a change in the level
of one or more market prices, rates, indices, volatilities, correlations or
other market factors, such as liquidity, will result in losses for a specified
position or portfolio. NiSource employs a VaR model to assess the market risk of
all open derivative financial instruments. NiSource estimates the one-day VaR
across all trading groups which utilize derivatives using either Monte Carlo
simulation or variance/covariance at a 95 percent confidence level. Based on the
results of the VaR analysis, the daily market risk exposure for power trading on
an average, high, and low basis was $0.4, $1.2, and $0.014 million during 1999,
respectively. The daily VaR for gas trading on an average, high and low basis
was $1.3, $2.1 and $0.4 million, during 1999, respectively. At December 31,
1998, the daily VaR for gas trading was not significant.

      NiSource implemented a VaR methodology in 1999 to introduce additional
market sophistication and to recognize the developing complexity of its
businesses.

Non-Trading Risks

COMMODITY MARKET RISK. Currently, commodity price risk resulting from
non-trading activities at the Energy Utilities is limited, since current
regulations allow the Energy Utilities to recoup any prudently incurred fuel and
gas costs through rate-making. As the utility industry undergoes deregulation,
however, the Energy Utilities will be providing services without the benefit of
the traditional rate-making and, therefore, will be more exposed to commodity
price risk. Additionally, NiSource enters into certain sales contracts with
customers based upon a fixed sales price and varying volumes which are
ultimately dependent upon the customer's supply requirements. NiSource utilizes
derivative financial instruments to reduce the commodity price risk based on
modeling techniques to anticipate these future supply requirements.

      INTEREST RATE RISK. Long-term debt is utilized as a primary source of
capital. A significant portion of this long-term debt consists of medium-term
notes. In addition, longer term fixed-price debt instruments have been used that
in the past have been refinanced when interest rates decreased. To the extent
that such refinancing is economical, refinancing these fixed-price instruments
will continue.

      CREDIT RISK. Credit risk arises in many of NiSource's business activities.
In sales and trading activities, credit risk arises because of the possibility
that a counterparty will not be able or willing to fulfill its obligations on a



                                       32

================================================================================

transaction on or before settlement date. In derivative activities, credit risk
arises when counterparties to derivative contracts, such as interest rate swaps,
are obligated to pay NiSource the positive fair value or receivable resulting
from the execution of contract terms. Exposure to credit risk is measured in
terms of both current and potential exposure. Current credit exposure is
generally measured by the notional or principal value of financial instruments
and direct credit substitutes, such as commitments and standby letters of credit
and guarantees. Current credit exposure includes the positive fair value of
derivative instruments. Because many of NiSource's exposures vary with changes
in market prices, NiSource also estimates the potential credit exposure over the
remaining term of transactions through statistical analyses of market prices. In
determining exposure, NiSource considers collateral and master netting
agreements, which are used to reduce individual counterparty risk, primarily in
connection with derivative products.

      FOREIGN CURRENCY RISK. NiSource is exposed to foreign currency risk
arising from equity investments in businesses owned and operated in foreign
countries. Exposures to these investments are periodically reviewed by
management and were not material to consolidated results in 1999.

      Refer to Consolidated Statement of Long-Term Debt for detailed information
related to NiSource's long-term debt outstanding and "Fair Value of Financial
Instruments" in Notes to Consolidated Financial Statements for current market
valuation of long-term debt. Refer to "Summary of Significant Accounting
Policies--Accounting for Price Risk Management Activities" for further
discussion of NiSource's risk management.

Risk

"Year 2000 issues" were concerned with the ability of electronic processing
equipment to process date sensitive information and recognize the last two
digits of a date as occurring in or after the year 2000. Any failure in any
system could have resulted in material operational and financial risks. Possible
scenarios included a system failure in a generating plant, an operating
disruption or delay in transmission or distribution of gas, electricity or
water, or an inability to interconnect with the systems of other utilities.
Failure to achieve year 2000 readiness could have had a material adverse effect
on results of operations, financial position and cash flows.

     The program to address risks associated with the year 2000 on both
information technology (IT) and non-IT systems was completed in a timely manner.

State of Readiness

The NiSource year 2000 program consisted of four phases: inventory (identifying
systems potentially affected by the year 2000), assessment (testing identified
systems), remediation (correcting or replacing non-compliant systems) and
validation (evaluating testing remediated systems to confirm compliance). All
phases in all subsidiaries were completed in a timely manner.

     Because NiSource depends on outside suppliers and vendors with similar year
2000 issues, the ability of those suppliers and vendors to provide an
uninterrupted supply of goods and services was assessed. Critical vendors and
suppliers were contacted in order to investigate their year 2000 efforts. In
addition, electricity and gas industry groups such as the North American
Electric Reliability Council, the Electric Power Research Institute and the
American Gas Association were helpful in evaluating the potential impact of year
2000 problems upon the electric grid systems and pipeline networks.

Costs

The total cost of the NiSource year 2000 program was $25.0 million. These costs
were funded from operations. Costs related to the maintenance or modification of
existing systems were expensed as incurred. Costs related to the acquisition of
replacement systems were capitalized. These costs did not have a material impact
on results of operations.

Contingency Plans

NiSource developed its contingency plans to address the possibility that any
mission-critical system would be non-compliant. This included identifying
alternate suppliers and vendors, conducting staff training and developing
communication plans. In addition, NiSource evaluated the ability to maintain or
restore service in the event of a power failure or operating disruption or
delay, along with the limited ability to mitigate the effects of a network
failure by isolating its own network from the non-compliant segments of the
greater network. These contingency plans were completed during the second
quarter of 1999 and reviewed during the fourth quarter of 1999. They were not
needed for the century rollover.

     Results NiSource did not experience any system failures as a result of the
year 2000 issue.

- --------------------------------------------------------------------------------
                      COMPETITION AND REGULATORY CHANGES
- --------------------------------------------------------------------------------

The regulatory frameworks applicable to the Energy Utilities, at both the state
and federal levels, are undergoing fundamental changes. These changes have
impacted and will continue to have an impact on NiSource's operations, structure
and profitability. At the same time, competition within the electric and gas
industries will create opportunities to compete for new customers and revenues.
Management has taken steps to become more competitive and profitable in this
changing environment, including partnering on energy projects with major
industrial customers, converting some of its generating units to allow use of
lower cost, low sulfur coal, providing its gas customers with increased customer
choice for new products and services, acquiring companies which increase our
scale and establishing subsidiaries that provide gas and develop new
energy-related products for residential, commercial and industrial customers.

     The Electric Industry. At the Federal level, the Federal Energy Regulatory
Commission (FERC) issued Order No. 888-A in 1996 which required all public
utilities owning, controlling or operating transmission lines to file
non-discriminatory open-access tariffs and offer wholesale electricity suppliers
and marketers the same transmission service they provide themselves. In 1997,
FERC approved Northern Indiana's open-access transmission tariff. On December
20, 1999, FERC issued a final rule addressing the formation and operation of
Regional Transmission Organizations (RTOs). The rule is intended to eliminate
pricing inequities in the provision of wholesale transmission service. NiSource
does not believe that compliance with the new rules will be material to future
earnings. Although wholesale customers currently represent a small portion of
Northern Indiana's electricity sales, it intends to continue its efforts to
retain and add wholesale customers by offering competitive rates and also
intends to expand the customer base for which it provides transmission services.

     At the state level, NiSource announced in 1997 and 1998 that if a consensus
could be reached regarding electric utility restructuring legislation, NiSource
would support a restructuring bill before the Indiana General Assembly. During
1999, discussions were held with the other investor-owned utilities in Indiana
and with other segments of the Indiana electric industry regarding the technical
and economic aspects of possible legislation leading to greater customer choice.
A consensus was not reached. Therefore, NiSource did not support legislation
regarding electric restructuring during the 2000 session of the Indiana General
Assembly. During 2000, discussions will continue with all segments of the
Indiana electric industry in an attempt to reach a consensus on electric
restructuring legislation for introduction during the 2001 session of the
Indiana General Assembly.

     The Gas Industry. At the Federal level, gas industry deregulation began in
the mid-1980s when FERC required interstate pipelines to provide
nondiscriminatory transportation services pursuant to unbundled rates. This
regulatory change permitted large industrial and commercial customers to
purchase their gas supplies either from the Energy Utilities or directly from
competing producers and marketers, which would then use the Energy Utilities'
facilities to transport the gas. More recently, the focus of deregulation in the
gas industry has shifted to the states.

     At the state level, the IURC approved in 1997 Northern Indiana's
Alternative Regulatory Plan (ARP) which implemented new rates and services that
included, among other things, unbundling of services for additional customer
classes (primarily residential and commercial users), negotiated services and
prices, a gas cost incentive mechanism, and a price protection program. The gas
cost incentive mechanism allows Northern Indiana to share any cost savings or
cost increases with its customers based upon a comparison of Northern Indiana's
actual gas supply portfolio cost to a market-based benchmark price. Phase I of
Northern Indiana's Customer Choice Pilot Program ended on March 31, 1999. This
pilot program offered 82,000 residential customers within St. Joseph County and
10,000 commercial customers throughout the NiSource service area the right to
choose alternative gas suppliers. Phase II of Northern Indiana's Customer Choice
Pilot Program commenced April 1, 1999 and will continue for a one-year period.
During this phase, Northern Indiana is offering customer choice to all 660,000
residential and 50,000 commercial customers throughout its gas service
territory. A limit of 150,000 residential and 20,000 commercial customers are
eligible to enroll in Phase II of the program. The IURC order allows NiSource's
natural gas marketing subsidiary to participate as a supplier of choice to
Northern Indiana customers. In addition, as Northern Indiana has allowed
residential and commercial customers to designate alternative gas suppliers, it
has also offered new services to all classes of customers including price
protection, negotiated sales and services, gas lending and parking, and new
storage services.

     In Massachusetts, Bay State implemented new unbundled rates and services
for all commercial-industrial customers in 1993, and launched one of the
nation's earliest residential and small commercial-industrial customer choice
pilot programs in 1996. The Bay State pilot, in which almost 28% of eligible
customers participated, is scheduled to conclude on April 1, 2000 when all
Massachusetts gas utilities are expected to begin making unbundled gas service
available to all customer classes pursuant to new statewide model terms and
conditions that are currently awaiting approval by the Massachusetts Department
of Telecommunications and Energy.

     In New Hampshire, Northern Utilities introduced unbundled tariffs and
services for all commercial-industrial customers in 1994. In 1998, the New
Hampshire Public Utilities Commission (NHPUC) formed a collaborative group to
investigate the merits of further unbundling and advise the NHPUC accordingly.
The collaborative group has recommended new model tariffs and regulation
designed to make unbundled services available to all commercial-industrial
customers statewide on November 1, 2000, with consideration of residential
unbundling at a later date. Hearings before the NHPUC regarding the
recommendations are expected to be held during the first quarter of 2000.

     In Maine, Northern Utilities introduced unbundled rates and services for
large commercial-industrial customers in December 1995 and expanded the
availability to all daily metered commercial and industrial customers on
November 1, 1999. In June 1999 the Maine Public Utilities Commission opened an
inquiry into the potential merits of further regulatory changes related to
unbundling. This inquiry is intended to investigate all the key elements of full
customer choice and will include a review of customer choice programs in
Massachusetts and New Hampshire.

     To date, the Energy Utilities have not been materially affected by
competition and management does not foresee substantial adverse affects in the
near future unless the current regulatory structure is substantially altered.
NiSource believes the steps that it has taken to deal with increased competition
have had and will continue to have significant positive effects in the next few
years.

This report contains forward-looking statements within the meaning of the
securities laws. Forward-looking statements include terms such as "may," "will,"
"expect," "believe," "plan" and other similar terms. NiSource cautions that,
while it believes such statements to be based on reasonable assumptions and
makes such statements in good faith, you cannot be assured that the actual
results will not differ materially from such assumptions or that the
expectations set forth in the forward-looking statements derived from these
assumptions will be realized. You should be aware of important factors that
could have a material impact on future results. These factors include weather,
the federal and state regulatory environment, the economic climate, regional,
commercial, industrial and residential growth in the service territories served
by NiSource's subsidiaries, customers' usage patterns and preferences, the speed
and degree to which competition enters the utility industry, the timing and
extent of changes in commodity prices, changing conditions in the capital and
equity markets and other uncertainties, all of which are difficult to predict,
and many of which are beyond NiSource's control.

provides natural gas, electricity and water to the public for residential,
commercial and industrial uses. NiSource was organized as an Indiana holding
company in 1987 under the name NIPSCO Industries Inc., and changed its name to
NiSource Inc. on April 14, 1999 to reflect its new direction as a multi-state
supplier of energy and water resources and related services.

   NiSource's gas business is comprised primarily of regulated gas utilities
that operate throughout northern Indiana and New England. In addition, NiSource
expanded its gas marketing, trading and storage operations with the April 1999
acquisition of TPC Corporation, now renamed EnergyUSA-TPC Corp. (TPC).
NiSource's electric business is comprised of a regulated electric utility that
operates in northern Indiana. The electric business also includes wholesale
sales and power trading activities. NiSource's regulated gas and electric
subsidiaries are collectively referred to as the "Energy Utilities." NiSource's
regulated water subsidiaries are collectively called the "Water Utilities."
Collectively the Energy and Water Utilities are referred to as the "Utilities."

   The Utilities are subject to regulation with respect to rates, accounting and
certain other matters by the Indiana Utility Regulatory Commission (IURC), the
Massachusetts Department of Telecommunications and Energy (MDTE), the New
Hampshire Public Utilities Commission (NHPUC), the Maine Public Utilities
Commission (MEPUC) and the Federal Energy Regulatory Commission (FERC),
collectively called the "Commissions." Market Hub Partners, L.P., which is a
subsidiary of TPC Gas Storage Services L.P., is subject to regulation by the
Texas Railroad Commission and FERC.

   Non-regulated energy and utility-related products and services are provided
through the "Products and Services" subsidiaries. Products and Services
subsidiaries perform energy-related services and offer products in connection
with these services, which include pipeline construction, repair and maintenance
of underground gas pipelines and locating and marking utility lines.

   In addition to the Utilities and the Products and Services subsidiaries,
NiSource has a wholly-owned subsidiary, NiSource Capital Markets, Inc. (Capital
Markets), which engages in financing activities for NiSource and certain of its
subsidiaries, excluding Northern Indiana Public Service Company (Northern
Indiana).

ANNOUNCEMENT OF MERGER AGREEMENT WITH COLUMBIA ENERGY GROUP
In June 1999, NiSource commenced a tender offer to acquire CEG. In December
1999, CEG acknowledged preliminary indications of interest from numerous other
third parties and invited formal bids from those companies

that had indicated a preliminary value higher than the NiSource tender offer
price of $74 per share. As a result, in December, NiSource wrote off the costs
associated with its tender offer. On February 11, 2000, the NiSource tender
offer expired.

     On February 28, 2000, after completion of the bidding process initiated by
CEG, NiSource and CEG announced approval of a merger agreement under which
NiSource will form a new holding company, which will acquire all of the
outstanding shares of CEG valued at approximately ~$6 billion. The new holding
company will also assume approximately $2.5 billion of CEG debt. Under the
agreement, CEG shareholders have the option to receive new holding company stock
for up to 30% of the outstanding CEG shares. Under the common stock option, each
CEG share will be exchanged for $74 in new holding company stock, based on the
average NiSource share price prior to the closing, but not more than 4.4848
shares of new holding company stock for each CEG share. Under the cash option,
each CEG share will be exchanged for $70 in cash plus a $2.60 face value unit
(consisting of a zero coupon debt security with a forward equity contract). A
commitment letter was accepted under which certain financial institutions
agreed, under specified conditions, to provide up to $6.0 billion to finance the
acquisition of CEG. The merger is conditioned upon, among other things, the
approvals of the shareholders of both companies and various regulatory
commissions. If NiSource shareholder approval is not obtained, the merger
agreement provides that the transaction will automatically be restructured to
eliminate the 30% common stock option for CEG shareholders.

     CEG, based in Herndon, Va., is one of the nation's leading energy services
companies, with assets of approximately $7 billion. Its operating companies
engage in virtually all phases of the natural gas business, including
exploration and production, transmission, storage and distribution, as well as
propane and petroleum product sales, electric power generation and retail energy
marketing. CEG sells natural gas to about 2 million customers in Kentucky,
Maryland, Ohio, Pennsylvania and Virginia. It owns 16,500 miles of interstate
gas pipelines that run from Louisiana to the Northeast.

                   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
- --------------------------------------------------------------------------------

BASIS OF PRESENTATION

The consolidated financial statements include the accounts of NiSource and its
majority-owned subsidiaries after the elimination of significant intercompany
accounts and transactions. Investments for which at least a 20% interest is
owned and certain joint ventures are accounted for under the equity method.
Investments with less than a 20% interest are accounted for under the cost
method. Certain reclassifications were made to conform the prior years'
financial statements to the current presentation.

     On February 12, 1999, NiSource acquired Bay State Gas Company (BSG) and its
subsidiaries. Accordingly, the consolidated financial statements and disclosures
include operating results from BSG from the date of acquisition through December
31, 1999.

     On April 1, 1999, NiSource acquired the stock of TPC. As a result of the
TPC acquisition, NiSource indirectly owned a 77.3% equity interest in Market Hub
Partners, L.P. (MHP), which stores natural gas in salt caverns. In the fourth
quarter of 1999 NiSource acquired the remaining interests in MHP. The
consolidated financial statements and disclosures include operating results of
TPC from the date of acquisition through December 31, 1999.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

OPERATING REVENUES

Except as discussed below, revenues are recorded as products and services are
delivered. However, utility revenues are billed to customers monthly on a cycle
basis. Effective January 1, 1999, revenues relating to energy trading operations
are recorded based upon changes in the fair values, net of reserves, of the
related energy trading contracts. Construction revenues are recognized on the
percentage of completion method whereby revenues are recognized in proportion to
costs incurred over the life of each project. Provisions for losses on
construction contracts, if any, are recorded in the period in which such losses
become probable.

DEPRECIATION AND MAINTENANCE

The Utilities provide depreciation on a straight-line method over the remaining
service lives of the electric, gas, water and common properties. The approximate
weighted average remaining lives for major components of electric, gas, and
water plant are as follows:

Electric:
  Electric generation plant.........................................   24 years
  Transmission plant................................................   26 years
  Distribution plant................................................   25 years
  Other electric plant..............................................   24 years
Gas:
  Gas storage plant.................................................   15 years
  Transmission plant................................................   18 years
  Distribution plant................................................   34 years
  Other gas plant...................................................   16 years
Water:
  Water source and treatment plant..................................   34 years
  Distribution plant................................................   68 years
  Other water plant.................................................   13 years

                                       42
<PAGE>   20
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
================================================================================

The depreciation provisions for utility plant, as a percentage of the original
cost, for the period ended December 31, 1999, 1998 and 1997 were as follows:

                                                       1999      1998     1997

  Electric........................................      3.7%      3.7%     3.6%
  Gas.............................................      4.4%      5.1%     5.1%
  Water...........................................      2.1%      2.1%     2.1%

     The Utilities follow the practice of charging maintenance and repairs,
including the cost of removal of minor items of property, to expense as
incurred. When property that represents a retired unit is replaced or removed,
the cost of such property is credited to utility plant, and such cost, together
with the cost of removal less salvage, is charged to the accumulated provision
for depreciation.

AMORTIZATION OF SOFTWARE COSTS

External and incremental internal costs associated with computer software
developed for internal use are capitalized. Capitalization of such costs
commences upon the completion of the preliminary stage of the project. Once the
installed software is ready for its intended use, such capitalized costs are
amortized on a straight-line basis over a period of five to ten years which the
FERC prescribes as reasonable useful life estimates for capitalized software.

PLANT ACQUISITION ADJUSTMENTS

Net utility plant includes amounts allocated to utility plant in excess of the
original cost as part of the purchase price allocation associated with the
acquisition of utility businesses, net of accumulated amortization. Net plant
acquisition adjustments were $722.8 million and $185.4 million at December 31,
1999 and December 31, 1998, respectively, and are being amortized over
forty-year periods from the respective dates of acquisition.

INTANGIBLE ASSETS

The excess of cost over the fair value of the net assets of non-utility
businesses acquired is recorded as goodwill. Goodwill of $125.7 million and
$61.9 million at December 31, 1999 and December 31, 1998, respectively, is being
amortized over a weighted average period of 27 years. Other intangible assets,
approximating $12.8 million and $7.7 million at December 31, 1999 and December
31, 1998, respectively, are being amortized over periods of four to eight years.
The recoverability of intangible assets is assessed on a periodic basis to
confirm that expected future cash flows will be sufficient to support the
recorded intangible assets. Accumulated amortization of intangible assets at
December 31, 1999 and December 31, 1998 was approximately $9.9 million and $4.6
million, respectively.

COAL RESERVES

The costs of reserves under a long-term mining contract to mine coal reserves
through the year 2001 are being recovered through the rate-making process as
such coal reserves are used to produce electricity.

ACCOUNTS RECEIVABLE

At December 31, 1999, $100.0 million of accounts receivable had been sold under
a sales agreement, which expires on May 31, 2002.

CUSTOMER ADVANCES AND CONTRIBUTIONS IN AID OF CONSTRUCTION

Certain developers install and provide for the installation of water main
extensions, which will be transferred to IWC upon completion. The cost of the
main extensions and the amount of any funds advanced for the cost of water mains
installed are included in customer advances for construction and are generally
refundable to the customer over a period of ten years. Advances not refunded
within ten years are permanently transferred to contributions in aid of
construction.

COMPREHENSIVE INCOME

Comprehensive income is reported in the consolidated statements of common
shareholders' equity. The components of accumulated other comprehensive income
include unrealized gains (losses), net of income taxes, on available for sale
securities ("securities") and on foreign currency translation adjustments
("foreign currency"). The accumulated amounts for these components are as
follows:

                                JAN. 1,     DEC. 31,    DEC. 31,     DEC. 31,

Securities....................   $ 2.7       $ 4.5       $ 3.6        $ 6.1
Foreign
  currency....................   $(0.1)      $(1.6)      $(2.5)       $(0.9)

STATEMENT OF CASH FLOWS

Temporary cash investments with an original maturity of three months or less are
considered to be cash equivalents.

     Cash paid during the periods reported for income taxes and interest was as
follows:

                                             1999       1998         1997
                                                      (In thousands)
Income taxes..................             $115,992    $127,713     $116,849
Interest, net of
  amounts
  capitalized.................              160,046     118,079      102,361

FUEL ADJUSTMENT CLAUSE

All metered electric rates contain a provision for adjustment in charges for
electric energy to reflect increases and decreases in the cost of fuel and the
fuel cost of purchased power through operation of a fuel adjustment clause. As
prescribed by order of the IURC applicable to metered retail rates, the
adjustment factor has been calculated based on the estimated cost of fuel and
the fuel cost of purchased power in a future three-month period. If two
statutory requirements relating to expense and return levels are satisfied, any
under-recovery or over-recovery caused by variances between estimated and

                                       43
<PAGE>   21
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
================================================================================

actual cost in a given three-month period will be included in a future filing.
Northern Indiana records any under-recovery or over-recovery as a current asset
or current liability until such time as it is billed or refunded to its
customers. The fuel adjustment factor is subject to a quarterly hearing by the
IURC and remains in effect for a three-month period.

   On August 18, 1999, the IURC issued a generic order which established new
guidelines for the recovery of purchased power costs through fuel adjustment
clauses. The IURC ruled that each utility had to establish a "benchmark" which
is the utility's highest on-system fuel cost per kilowatt-hour (kwh) during the
most recent annual period. The IURC stated that if the weekly average of a
utility's purchased power costs were less than the "benchmark," these costs per
kwh should be considered net energy costs which are presumed "fuel costs
included in purchased power." If the weekly average of a utility's purchased
power costs exceeded the "benchmark," the utility would need to submit
additional evidence demonstrating the reasonableness of these costs. The Office
of Utility Consumer Counselor (OUCC) has appealed the August 18 order to the
Indiana Court of Appeals.

GAS COST ADJUSTMENT CLAUSE
All metered gas sales rates contain an adjustment factor, which reflects the
increases and decreases in the cost of purchased gas, contracted gas storage and
storage transportation charges. Each gas cost adjustment factor is subject to a
monthly, quarterly, semi-annual or annual hearing by the state Commissions and
remains in effect for a one-month, three-month, six-month or twelve-month
period. On August 11, 1999, the IURC approved a flexible gas cost adjustment
mechanism for Northern Indiana. Under the new procedure, the demand component of
the adjustment factor will be determined, after hearings and IURC approval, and
made effective on November 1 of each year. The demand component will remain in
effect for one year until a new demand component is approved by the IURC. The
commodity component of the adjustment factor will be determined by monthly
filings, which will become effective on the first day of each calendar month,
subject to refund. The monthly filings do not require IURC approval but will be
reviewed by the IURC during the annual hearing that will take place regarding
the demand component filing.

   If the statutory requirement relating to the level of return for the gas
utilities is satisfied, any under-recovery or over-recovery caused by variances
between estimated and actual cost in a given one-month, three-month, six-month
or twelve-month period will be included in a future filing. Any under-recovery
or over-recovery is recorded as a current asset or current liability until such
time it is billed or refunded to customers.

   Northern Indiana's gas cost adjustment factor includes a gas cost incentive
mechanism (GCIM) which allows the sharing of any cost savings or cost increases
with customers based on a comparison of actual gas supply portfolio cost to a
market-based benchmark price.

NATURAL GAS IN STORAGE
Both the last-in, first-out (LIFO) inventory methodology and the weighted
average methodology are used to value natural gas in storage. Based on the
average cost of gas purchased under the LIFO method in December 1999 and
December 1998, the estimated replacement cost of gas in storage (current and
non-current) at December 31, 1999 and December 31, 1998 exceeded the stated LIFO
cost by $48.9 million and $33.7 million, respectively. Inventory valued using
LIFO was $23.0 million and $50.8 million at December 31, 1999 and December 31,
1998, respectively. Inventory valued using the weighted average methodology was
$40.8 million and $18.8 million at December 31, 1999 and December 31, 1998,
respectively.

ACCOUNTING FOR PRICE RISK MANAGEMENT ACTIVITIES
NiSource is exposed to commodity price risk in its natural gas and electric
operations. A variety of commodity-based derivative financial instruments are
utilized to reduce this price risk. When these derivatives are used to reduce
price risk in non-trading operations such as activities in gas supply for
regulated gas utilities, certain customer choice programs for residential
customers and other retail customer activity, gains and losses on these
derivative financial instruments are deferred as assets and liabilities and are
recognized in earnings concurrent with the disposition of the underlying
physical commodity. In certain circumstances, a derivative financial instrument
will serve to hedge the acquisition cost of natural gas injected into storage.
In this situation, the gain or loss on the derivative financial instrument is
deferred as part of the cost basis of gas in storage and recognized upon the
ultimate disposition of the gas. If a derivative financial instrument contract
is terminated early because it is probable that a transaction or forecasted
transaction will not occur, any gain or loss as of such date is immediately
recognized in earnings. If a derivative financial instrument is terminated for
other economic reasons, any gains or losses as of the termination date is
deferred and recorded when the associated transaction or forecasted transaction
affects earnings.

   NiSource also uses derivative financial instruments in connection with
trading activities at its power trading and certain gas marketing and trading
operations. These derivatives, along with the related physical contracts, are
recorded at fair value pursuant to Emerging Issues Task Force (EITF) Issue No.
98-10, "Accounting for Energy Trading and Risk Management Activities." Because
the majority of our trading activities started in 1999, the impact of adopting
EITF Issue No. 98-10 on January 1, 1999, was insignificant. Transactions related
to utility system load management do not qualify as a trading activity under
EITF Issue No. 98-10 and are accounted for on an accrual basis. NiSource refers
to this activity as Power Marketing.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
================================================================================

IMPACT OF ACCOUNTING STANDARDS
The Financial Accounting Standards Board (FASB) has issued Statement of
Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative
Instruments and Hedging Activities," in June 1998 and SFAS No. 137, "Accounting
for Derivative Instruments and Hedging Activities--Deferral of the Effective
Date of FASB Statement No. 133" in June 1999. Statement No. 133 standardizes the
accounting for derivative instruments, including certain derivative instruments
embedded in other contracts, by requiring that a company recognize those items
as assets or liabilities in the balance sheet and measure them at fair value.
The standard also suggests in certain circumstances commodity based contracts
may qualify as derivatives. Special accounting within this Statement generally
provides for matching of the timing of gain or loss recognition of derivative
instruments qualifying as a hedge with the recognition of changes in the fair
value of the hedged asset or liability through earnings, and requires that a
company must formally document, designate and assess the effectiveness of
transactions that receive hedge accounting treatment. The Statement also
provides that the effective portion of a hedging instrument's gain or loss on a
forecasted transaction be initially reported in other comprehensive income and
subsequently reclassified into earnings when the hedged forecasted transaction
affects earnings. Unless those specific hedge accounting criteria are met, SFAS
No. 133 requires that changes in derivatives' fair value be recognized currently
in earnings.

     SFAS No. 133, as amended by SFAS No. 137, is not effective for NiSource
until January 1, 2001. SFAS No. 133 must be applied to (a) derivative
instruments and (b) certain derivative instruments embedded in hybrid contracts.
With respect to hybrid instruments, a company may elect to apply SFAS No. 133,
as amended, to (1) all hybrid instruments, (2) only those hybrid instruments
that were issued, acquired or substantively modified after December 31, 1997, or
(3) only those hybrid instruments that were issued, acquired or substantively
modified after December 31, 1998.

     NiSource anticipates adopting SFAS No. 133 on January 1, 2001, but has not
yet determined the impact or method of adoption. The fair value of derivatives
used in price risk management are described in "Risk Management Activities."

     The fair value of these derivatives would be recognized as assets or
liabilities on the balance sheet consistent with the current accounting
treatment for certain freestanding derivatives. NiSource has not yet quantified
the other effects of adopting SFAS No. 133 on its financial statements. However,
the Statement could increase volatility in earnings and other comprehensive
income.

REGULATORY ASSETS
The Utilities' operations are subject to the regulation of the appropriate state
commission and, in the case of the Energy Utilities, the FERC. Accordingly, the
Utilities' accounting policies are subject to the provisions of SFAS No. 71,
"Accounting for the Effects of Certain Types of Regulation." The Utilities
monitor changes in market and regulatory conditions and the resulting impact of
such changes in order to continue to apply the provisions of SFAS No. 71 to some
or all of their operations. As of December 31, 1999 and December 31, 1998, the
regulatory assets identified below represent probable future revenues to the
Utilities as these costs are recovered through the rate-making process. If a
portion of the Utilities' operations becomes no longer subject to the provisions
of SFAS No. 71, a write-off of certain regulatory assets might be required,
unless some form of transition cost recovery is established by the appropriate
regulatory body which would meet the requirements under generally accepted
accounting principles for continued accounting as regulatory assets during such
recovery period. Regulatory assets were comprised of the following items:

CARRYING CHARGES AND DEFERRED DEPRECIATION
Upon completion of R. M. Schahfer Units 17 and 18, Northern Indiana capitalized
the carrying charges and deferred depreciation in accordance with orders of the
IURC until the cost of each unit was allowed in rates. Such carrying charges and
deferred depreciation are being amortized over the remaining life of each unit.

     Northern Indiana has capitalized carrying charges and deferred depreciation
and certain operating expenses relating to its scrubber service agreement for
its Bailly Generating Station in accordance with an order of the IURC. The
accumulated balance of the deferred costs and related carrying charges is being
amortized over the remaining life of the scrubber service agreement.

FOREIGN CURRENCY TRANSLATION
Translation gains or losses are based upon the end-of-period exchange rate and
are recorded as a separate component of other comprehensive income reflected in
the Consolidated Statement of Shareholders' Equity.

INVESTMENTS IN REAL ESTATE
A series of affordable housing projects are held as investments and accounted
for using the equity method. These investments include certain tax benefits,
including low-income housing tax credits and tax deductions for operating losses
of the housing projects. Investments, at equity, include $33.3 million and $34.0
million relating to affordable housing projects at December 31, 1999 and
December 31, 1998, respectively.

INCOME TAXES
The liability method of accounting is used for income taxes under which deferred
income taxes are recognized, at currently enacted income tax rates, to reflect
the tax effect of temporary differences between the book and tax bases of
assets and liabilities. Deferred investment tax credits are being amortized
over the life of the related property.

ACQUISITIONS
On February 12, 1999, the acquisition of BSG was completed for approximately
$560.1 million in cash and NiSource common shares. The $237.7 million cash
portion was partially financed by the issuance of Corporate Premium Income
Equity Securities (Corporate PIES) and partially financed by the issuance of the
Puttable Reset Securities (PURS). The acquisition was accounted for as a
purchase, and the purchase price was allocated to the assets acquired and
liabilities assumed based on their estimated fair values. The accompanying
financial statements reflect the allocation of the purchase price.

     Assets acquired and liabilities assumed in the acquisition of BSG were
comprised of the following:

applicable Corporate PIES and additional income taxes, as if the acquisition had
occurred on January 1, 1999 and 1998 for the twelve month results.

     On April 1, 1999, NiSource acquired the stock of TPC, a Houston-based
natural gas marketing and storage company, for approximately $150 million in
cash. The acquisition was accounted for as a purchase, with the purchase price
allocated to the assets and liabilities acquired based on their estimated fair
values. As a result of the TPC acquisition, NiSource had an indirect investment
in the amount of $126.0 million, representing a 77.3% interest in MHP. During
the fourth quarter of 1999, NiSource purchased the remaining interests in MHP.
The accompanying financial statements reflect the preliminary allocation of the
purchase price. Assets acquired and liabilities assumed in the acquisition of
TPC and MHP were comprised of the following:

                  NESI ENERGY MARKETING CANADA LTD. LITIGATION
- --------------------------------------------------------------------------------
On October 31, 1996, NiSource's subsidiary NiSource Energy Services Canada Ltd.
(NESI Canada) acquired 70% of the outstanding shares of Chandler Energy Inc., a
gas marketing and trading company located in Calgary, Alberta, and subsequently
renamed it NESI Energy Marketing Canada Ltd. (NEMC). Between November 1 and
November 27, 1996, gas prices in the Calgary market increased dramatically. As a
result, NEMC was selling gas, pursuant to contracts entered into prior to the
acquisition date, at prices substantially below its costs to acquire such gas.
On November 27, 1996, NEMC ceased doing business and sought protection from its
creditors under the Companies' Creditors Arrangement Act, a Canadian corporate
reorganization statute. NEMC was declared bankrupt as of December 12, 1996.

Certain creditors of NEMC have filed claims in the Canadian courts against
NiSource, Capital Markets, NI Energy Services, Inc. and NESI Canada, alleging
certain misrepresentations relating to NEMC's financial condition and claiming
damages. In addition, certain creditors of NEMC have, through the Canadian
bankruptcy court, asserted fraudulent transfer and other claims against
NiSource, Capital Markets, NI Energy Services, Inc., NESI Canada and the
directors of NEMC. NiSource intends to vigorously defend against such claims and
any other claims seeking to assert that any party other than NEMC is responsible
for NEMC's liabilities. Management believes that any loss relating to NEMC will
not be material to the financial position or results of operations of NiSource.

- --------------------------------------------------------------------------------
                             ENVIRONMENTAL MATTERS
- --------------------------------------------------------------------------------
General
The operations of NiSource are subject to extensive and evolving federal, state
and local environmental laws and regulations intended to protect public health
and the environment. Such environmental laws and regulation affect operations as
they relate to impacts on air, water and land.

Superfund
Because several NiSource subsidiaries are a "potentially responsible party"
(PRP) under the Comprehensive Environmental Response, Compensation and Liability
Act (CERCLA) at several waste disposal sites, as well as at former
manufactured-gas plant sites which it, or its corporate predecessors, own or
owned or operated, it may be required to share in the cost of clean up of such
sites. A program was instituted to investigate former manufactured-gas plant
sites where it is the current or former owner, which investigation has
identified forty-six such sites. Initial sampling has been conducted at thirty
sites. Investigation activities have been completed at twenty-three sites and
remedial measures have been selected or implemented at sixteen sites. NiSource
intends to continue to evaluate its facilities and properties with respect to
environmental laws and regulations and take any required corrective action.

   In an effort to recover a portion of the costs related to the former
manufactured gas plants, various companies that provided insurance coverage
which NiSource believed covered costs related to former manufactured-gas plant
sites were approached. Northern Indiana filed claims in Indiana state court
against various insurance companies, seeking coverage for costs associated with
several manufactured-gas plant sites and damages for alleged misconduct by some
of the insurance companies. Settlements have been reached with all insurance
companies. Additionally, agreements have been reached with other Indiana
utilities relating to cost sharing and management of the investigation and
remediation of several former manufactured-gas plant sites at which Northern
Indiana and such utilities or their predecessors were operators or owners.

   BSG and Northern Utilities, Inc. have rate recovery for environmental
response costs in Maine, Massachusetts and New Hampshire. The rate treatment
allows for the recovery of 100% of prudently incurred costs for investigation
and remediation over a 5-7 year period from date of payment. Recoveries from
third parties or insurance companies in Maine and Massachusetts are allocated
50% to rate payers and 50% to shareholders. In New Hampshire 100% of any
recoveries from third parties or insurance companies are returned to rate
payers.

   As of December 31, 1999, a reserve of approximately $23.8 million has been
recorded to cover probable corrective actions. The ultimate liability in
connection with these sites will depend upon many factors, including the volume
of material contributed to the site, the number of other PRPs and their
financial viability, the extent of corrective actions required and rate
recovery. Based upon investigations and management's understanding of current
environmental laws and regulations, NiSource believes that any corrective
actions required, after consideration of insurance coverages, contributions from
other PRPs and rate recovery, will not have a material effect on its financial
position or results of operations.

Clean Air Act
The Clean Air Act Amendments of 1990 (CAAA) imposed limits to control acid rain
on the emission of sulfur dioxide and nitrogen oxides (NOx) which become fully
effective in 2000. All of NiSource's facilities are already in compliance with
the sulfur dioxide limits. NiSource has already taken most of the steps
necessary to meet the NOx limits.

   The CAAA also contain other provisions that could lead to limitations on
emissions of hazardous air pollutants and other air pollutants (including



                                       47

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
================================================================================

NOx as discussed below), which may require significant capital expenditures for
control of these emissions. Until specific rules have been issued that affect
NiSource's facilities, what these requirements will be or the costs of complying
with these potential requirements cannot be predicted.

NITROGEN OXIDES
During 1998, the Environmental Protection Agency (EPA) issued a final rule, the
NOx State Implementation Plan (SIP) call, requiring certain states, including
Indiana, to reduce NOx levels from several sources, including industrial and
utility boilers. The EPA stated that the intent of the rule is to lower regional
transport of ozone impacting other states' ability to attain the federal ozone
standard. According to the rule, the State of Indiana must issue regulations
implementing the control program. The State of Indiana, as well as some other
states, filed a legal challenge in December 1998 to the EPA NOx SIP call rule.
Lawsuits have also been filed against the rule by various groups, including
utilities. On May 25, 1999, the D.C. Circuit Court of Appeals issued an order
staying the NOx SIP call rule's September 30, 1999 deadline for the state
submittals until further order of the court. Any resulting NOx emission
limitations could be more restrictive than those imposed on electric utilities
under the CAAA's acid rain NOx reduction program described above. NiSource is
evaluating the EPA's final rule and any potential requirements that could result
from the final rule as implemented by the State of Indiana. NiSource believes
that the costs relating to compliance with the new standards may be substantial,
but such costs depend upon the outcome of the current litigation and the
ultimate control program agreed to by the targeted states and the EPA. Northern
Indiana is continuing its programs to reduce NOx emissions and NiSource will
continue to closely monitor developments in this area.

   In a related matter to EPA's NOx SIP call, several Northeastern states have
filed petitions with the EPA under Section 126 of the Clean Air Act. The
petitions allege harm and request relief from sources of emissions in the
Midwest that allegedly cause or contribute to ozone nonattainment in their
states. NiSource is monitoring EPA's decisions on these petitions and existing
litigation to determine the impact of these developments on Northern Indiana's
programs to reduce NOx emissions.

   The EPA issued final rules revising the National Ambient Air Quality
Standards for ozone and particulate matter in July 1997. On May 14, 1999, the
United States Court of Appeals for the D.C. Circuit remanded the new rules for
both ozone and particulate matters to the EPA. Once rectified, the revised
standards could require additional reductions in sulfur dioxide, particulate
matter and NOx emissions from coal-fired boilers (including Northern Indiana's
generating stations) beyond measures discussed above. Final implementation
methods will be set by the EPA as well as state regulatory authorities. NiSource
believes that the costs relating to compliance with any new limits may be
substantial but are dependent upon the ultimate control program agreed to by the
targeted states and the EPA. NiSource will continue to closely monitor
developments in this area and anticipates the exact nature of the impact of the
new limits on its operations will not be known for some time.

   In a letter dated September 15, 1999, the Attorney General of the State of
New York alleged that Northern Indiana violated the Clean Air Act by
constructing a major modification of one of its electric generating stations
without obtaining pre-construction permits required by the Prevention of
Significant Deterioration (PSD) program. The major modification allegedly took
place at the R. M. Schahfer Station when, "in approximately 1995-1997, Northern
Indiana upgraded the coal handling system at Unit 14 at the plant." While
Northern Indiana is investigating these allegations, Northern Indiana does not
believe that the modifications required pre-construction review under the PSD
program and believes that all appropriate permits were acquired.

CARBON DIOXIDE
Initiatives are being discussed both in the United States and worldwide to
reduce so-called "greenhouse gases" such as carbon dioxide and other by-products
of burning fossil fuels. Reduction of such emissions could result in significant
capital outlays or operating expenses to NiSource.

CLEAN WATER ACT AND RELATED MATTERS
NiSource's wastewater and water operations are subject to pollution control and
water quality control regulations, including those issued by the EPA and the
States of Indiana, Louisiana, Massachusetts and Texas.

   Under the Federal Clean Water Act and state regulations, NiSource must obtain
National Pollutant Discharge Elimination System permits for water discharges
from various facilities, including electric generating and water treatment
stations and a propane plant. These facilities either have permits for their
water discharge or they have applied for a permit renewal of any expiring
permits. These permits continue in effect pending review of the current
applications.

   Under the Federal Safe Drinking Water Act (SDWA), the Water Utilities are
subject to regulation by the EPA for the quality of water sold and treatment
techniques used to make the water potable. The EPA promulgates nationally-
applicable maximum contaminant levels (MCLs) for contaminants found in drinking
water. Management believes that the Water Utilities are currently in compliance
with all MCLs promulgated to date. The EPA has continuing authority, however, to
issue additional regulations under the SDWA. In August 1996, Congress amended
the SDWA to allow the EPA more authority to weigh the costs and benefits of
regulations being considered in some, but not all, cases. In December 1998, EPA
promulgated two National Primary Drinking Water rules, the Interim Enhanced
Surface Water Treatment Rule and the Disinfectants and Disinfection Byproducts
Rule. The Water Utilities must comply with these rules by December 2001.
Management does not believe that significant changes will be required for the
Water Utilities' operations to comply with these rules; however, some


                                       48
<PAGE>   26
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
================================================================================

cost expenditures for equipment modifications or enhancements may
be necessary to comply with the Interim Enhanced Surface Water Treatment Rule.
Additional rules are anticipated to be promulgated under the 1996 amendments.
Compliance with such rules could be costly and could require substantial changes
in the Water Utilities' operations.

     Under a 1991 law enacted by the Indiana legislature, a water utility may
petition the IURC for prior approval of its plans and estimated expenditures
required to comply with the provisions of, and regulations under, the Federal
Clean Water Act and SDWA. Upon obtaining such approval, a water utility may
include such costs in its rate base for rate-making purposes, to the extent of
its estimated costs as approved by the IURC, and recover its costs of developing
and implementing the approved plans if statutory standards are met. The capital
costs for such new systems, equipment or facilities or modifications of existing
facilities may be included in a water utility's rate base upon completion of
construction of the project or any part thereof. Such an addition to rate base,
however, would effect a change in water rates. NiSource's principal water
utility, IWC, has agreed to a moratorium on water rate increases until 2002.
Therefore, recovery of any increased costs discussed above may not be timely.

- --------------------------------------------------------------------------------
                                  INCOME TAXES
- --------------------------------------------------------------------------------

Deferred income taxes are recognized as costs in the rate-making process by the
Commissions having jurisdiction over the rates charged by the Utilities.
Deferred income taxes are provided as a result of provisions in the income tax
law that either require or permit certain items to be reported on the income tax
return in a different period than they are reported in the consolidated
financial statements. These taxes are reversed by a debit or credit to deferred
income tax expense as the temporary differences reverse. Investment tax credits
have been deferred and are being amortized to income over the life of the
related property.

   To the extent certain deferred income taxes of the Utilities are recoverable
or payable through future rates, regulatory assets and liabilities have been
established. Regulatory assets are primarily attributable to undepreciated
allowance for funds used during construction-equity ~(AFUDC) and the cumulative
net amount of other income tax timing differences for which deferred taxes had
not been provided in the past, when regulators did not recognize such taxes as
costs in the rate-making process. Regulatory liabilities are primarily
attributable to the Utilities' obligation to credit to ratepayers deferred
income taxes provided at rates higher than the current federal income tax rate
currently being credited to ratepayers using the average rate assumption method
and unamortized deferred investment tax credits.

   The components of the net deferred income tax liability at December 31, 1999
and December 31, 1998 were as follows:

and is based on a plan benefit formula which considers expected future salary
increases. Discount rates of 7.75% and 7.00% and rates of increase in
compensation levels of 4.5% and 4.5% were used to determine the benefit
obligations at December 31, 1999 and 1998, respectively.

  The long-term portion of prepaid pension cost amounts for 1999 and 1998 are
included in "Prepayments and other" in the Consolidated Balance Sheet.

  Certain union employees participate in industry-wide, multi-employer pension
plans which provide for monthly benefits based on length of service. Specified
amounts per compensated hour for each employee are contributed to the trustees
of these plans. Contributions of $2.5 million, $2.0 and $1.7 million were made
to these plans for the years ended December 31, 1999, 1998 and 1997,
respectively. The relative position of each employer participating in these
plans with respect to the actuarial present value of accumulated plan benefits
and net assets available for benefits is not available.

NiSource provides certain health care and life insurance benefits for certain
retired employees. The majority of employees may become eligible for these
benefits if they reach retirement age while working for NiSource.

  The expected cost of such benefits is accrued during the employees' years of
service. Current rates include postretirement benefit costs on an accrual basis,
including amortization of the regulatory assets that arose prior to inclusion of
these costs in rates. Cash contributions are remitted to grantor trusts.

  In order to determine the APBO at December 31, 1999, a discount rate of 7.75%
and a pre-Medicare medical trend rate of 6% to a long-term rate of 5% was used,
and at December 31, 1998, a discount rate of 7% and a pre-Medicare medical trend
rate of 7% declining to a long-term rate of 5% was used.

  Net periodic postretirement benefit costs, before consideration of the
rate-making discussed previously, for the years ended December 31, 1999, 1998
and 1997 include the following components:

  Assumptions used in the determination of 1999, 1998 and 1997 net periodic
postretirement benefit costs were as follows:

<TABLE>
<CAPTION>
                                                                                      1999             1998             1997

Discount rate.............................................................            7.00%            7.00%            7.75%
Rate of increase in compensation levels...................................            4.50%            4.50%            5.50%
Assumed annual rate of increase in health care benefits...................            7.00%            8.00%            8.00%

</TABLE>

The effect of a 1% increase in the assumed health care cost trend rates for each
future year would increase the accumulated postretirement benefit obligation at
December 31, 1999 by approximately $25.6 million, and increase the aggregate of
the service and interest cost components of plan costs by approximately $5.2
million for the year ended December 31, 1999. The effect of a 1% decrease in the
assumed health care cost trend rates

================================================================================

for each future year would decrease the accumulated postretirement benefit
obligation at December 31, 1999 by approximately $21.1 million, and decrease the
aggregate of the service and interest cost components of plan costs by
approximately $4.0 million. Amounts disclosed above could be changed
significantly in the future by changes in health care costs, work force
demographics, interest rates, or plan changes.

                             COMMON SHARE DIVIDEND
- --------------------------------------------------------------------------------

During the next few years, NiSource's ability to pay dividends will depend upon
dividends it receives from Northern Indiana. Northern Indiana's Indenture dated
August 1, 1939, as amended and supplemented (Indenture), provides that it will
not declare or pay any dividends on any class of capital stock (other than
preferred or preference stock) except out of the earned surplus or net profits
of Northern Indiana. At December 31, 1999, Northern Indiana had approximately
$136.1 million of retained earnings (earned surplus) available for the payment
of dividends. Future dividends will depend upon adequate retained earnings,
adequate future earnings and the absence of adverse developments.
- --------------------------------------------------------------------------------
                               EARNINGS PER SHARE
- --------------------------------------------------------------------------------
Basic earnings per share were computed by dividing net income, reduced for
preferred dividends, by the average number of common shares outstanding during
the period. The diluted earnings per share calculation assumes the conversion of
nonqualified stock options and the equity forward share purchase contract into
common shares.

     The net income, preferred dividends and shares used to compute basic and
diluted earnings per share is presented in the following table:

On April 8, 1998, shareholders approved an increase in the number of authorized
common shares without par value from 200,000,000 shares to 400,000,000 shares.
All references to numbers of common shares reported, including per share amounts
and stock option data, have been adjusted to reflect the two-for-one stock split
paid February 20, 1998.

SHARE PURCHASE RIGHTS PLAN
Each Right, when exercisable, would initially entitle the holder to purchase
from NiSource one two-hundredth of a share of Series A Junior Participating
Preferred Share, without par value, at a price of $30 per one two-hundredth of a
share. In certain circumstances, if an acquirer ~obtained 25% of NiSource's
outstanding shares, or merged into NiSource or merged NiSource into the
acquirer, the Rights would entitle the holders to purchase NiSource's or the
acquirer's common shares for one-half of the market price. The Rights will not
dilute NiSource's common shares nor affect earnings per share unless they become
exercisable for common shares. The Plan was not adopted in response to any
specific attempt to acquire control of NiSource. The Rights are not currently
exercisable. On February 17, 2000, the Board of Directors of NiSource adopted a
new Share Purchase Rights Plan which has substantially the same terms as the
existing Share Purchase Rights Plan.

COMMON SHARE REPURCHASES
The Board has authorized the repurchase of 62.1 million common shares, subject
to certain limits. At December 31, 1999, approximately 56.2 million shares had
been repurchased at an average price of $16.98 per share.

EQUITY FORWARD SHARE PURCHASE CONTRACT
During the second quarter of 1999, a forward purchase contract was entered into
covering the purchase of up to 5% of NiSource's outstanding common shares. At
the end of each quarterly period during the term of the forward purchase
contract, NiSource has the option, but not the obligation, to settle the forward
purchase contract with respect to all or a portion of the common shares held by
the counterparty. As of December 31, 1999, the counterparty informed NiSource
that approximately 5.6 million shares had been purchased at a weighted average
cost of $26.90 per share. NiSource has the option to settle with the
counterparty by means of physical, net cash or net share settlement. On a
quarterly basis, NiSource will pay the counterparty a fee based on the amount
paid for common shares purchased by the counterparty, and the counterparty will
remit dividends received on shares owned. All such amounts paid and remitted
under the contract are reflected in equity contract costs of common
shareholders' equity. The net amount was a charge of $658,128 for the year
ending December 31, 1999.

     NiSource will be obligated to settle the forward purchase contract with
respect to all the remaining common shares in May 2003, or under certain
circumstances after an extension period of up to six months, at NiSource's
option. As of December 31, 1999, the nominal amount and fair value of the equity
forward purchase contract was approximately $150 million and $100 million,
respectively.

                           LONG-TERM INCENTIVE PLANS
- --------------------------------------------------------------------------------

There are two long-term incentive plans for key management employees that were
approved by shareholders on April 13, 1988 (1988 Plan) and April 13, 1994 (1994
Plan), each of which provides for the issuance of up to 5.0 million common
shares to key employees through April 1998 and April 2004, respectively. The
1988 Plan, as amended and restated, and the 1994 Plan, as amended and restated,
were re-approved by shareholders at the 1999 Annual Meeting of Shareholders,
held on April 14, 1999.

     At December 31, 1999, there were 1.8 million shares reserved for future
awards under the 1994 Plan. The Plans permit the following types of grants,
separately or in combination: nonqualified stock options, incentive stock
options, restricted stock awards, stock appreciation rights and performance
units. No incentive stock options or performance units were outstanding at
December 31, 1999. Under the Plans, the exercise price of each option equals the
market price of common stock on the date of grant. Each option has a maximum
term of ten years and vests one year from the date of grant.

     In connection with the acquisition of BSG, all outstanding BSG nonqualified
stock options were replaced with NiSource nonqualified stock options. The
replacement of such options did not change their original vesting provisions,
terms or fair values. Information regarding these options can be found in the
following tables about changes in nonqualified stock options under the caption
"converted."

     Stock appreciation rights (SARs) may be granted only in tandem with stock
options on a one-for-one basis and are payable in cash, NiSource's common
shares, or a combination thereof. There were no SARs outstanding at December 31,
1999. Restricted stock awards are restricted as to transfer and are subject to
forfeiture for specific periods from the date of grant. Restrictions on shares
awarded in 1995 lapse five years from date of grant, and vesting varies from 0%
to 200% of the number awarded, subject to specific earnings per share and stock
appreciation goals. Restrictions on shares awarded in 1998 and 1999 lapse two
years from date of grant and vesting varies from 0% to 100% of the number
awarded, subject to specific performance goals. If a participant's employment is
terminated prior to vesting other than by reason of death, disability or
retirement, restricted shares are forfeited. There were 513,500, 534,666 and
542,666 restricted shares outstanding at December 31, 1999, 1998 and 1997,
respectively.

     The Nonemployee Director Stock Incentive Plan, which was approved by
shareholders, provides for the issuance of up to 200,000 common shares to
nonemployee directors. The Plan provides for awards of common shares which vest
in 20% per year increments, with full vesting after five years. The Plan also
allows for the award of nonqualified stock options, subject to immediate vesting
in the event of the director's death or disability, or a change in control of
NiSource. If a director's service on the Board is terminated for any reason
other than retirement at or after age seventy, death or disability, any common
shares not vested as of the date of termination are forfeited. As of December
31, 1999, 75,500 shares had been issued under the Plan.

   These plans are accounted for under Accounting Principles Board Opinion No.
25, under which no compensation cost has been recognized for nonqualified stock
options. The compensation cost that was charged against net income for
restricted stock awards was $3.5 million, $1.9 million and $2.1 million for the
years ended December 31, 1999, 1998 and 1997, respectively. Had compensation
cost for nonqualified stock options been determined consistent with SFAS No. 123
"Accounting for Stock-Based Compensation," net income and earnings per average
common share would have been reduced to the following pro forma amounts:

     The fair value of each option granted as used to determine pro forma net
income is estimated as of the date of grant using the Black-Scholes option
pricing model with the following weighted average assumptions used for grants in
the years ended December 31, 1999, 1998 and 1997 respectively: risk-free
interest rate of 5.87%, 5.29% and 6.19%; expected dividend yield of $1.02, $0.96
and $0.90 per share; expected option term of five and one-quarter years for 1999
and 1998, and five years for 1997; and expected volatility of 15.72% for 1999
and 13.09% for 1998 and 12.2% for 1997.

The sinking fund requirements and maturities of long-term debt outstanding at
December 31, 1999, for each of the four years subsequent to December 31, 2000,
were as follows:

YEAR ENDING DECEMBER 31,                       (In thousands)

2002.................................................$119,183
2003.................................................$157,451

Unamortized debt expense, premium and discount on long-term debt applicable to
outstanding bonds are being amortized over the lives of such bonds.
Reacquisition premiums have been deferred and are being amortized. These
premiums are not earning a return during the recovery period.

   The first mortgage bonds constitute a direct first mortgage lien upon certain
utility property and franchises. Certain trust indentures require annual sinking
or improvement payments amounting to .50% of the maximum aggregate amount
outstanding. As permitted, this requirement has been satisfied by substituting a
portion of permanent additions to utility plant.

   Northern Indiana is authorized to issue and sell up to $217,692,000
Medium-Term Notes, Series E, with various maturities, for purposes of
refinancing certain first mortgage bonds and medium-term notes. As of December
31, 1999, $139.0 million of these medium-term notes had been issued with various
interest rates and maturities.

   In February 1999, $35.0 million of ten-year medium term notes were issued at
a rate of 5.99% with a maturity date of February 1, 2009 and $45.0 million of
twenty-year medium term notes were issued at a rate of 6.61% with a maturity
date of February 1, 2019. The majority of the proceeds were used to reduce
existing credit facilities and the remaining proceeds were used for general
corporate purposes.

   The financial obligations of Capital Markets are subject to a Support

Markets. Restrictions in the Support Agreement prohibit recourse on the part of
Capital Markets' creditors against the stock and assets of Northern Indiana that
are owned by NiSource. Under the terms of the Support Agreement, in addition to
the cash flow of cash dividends paid to NiSource by any of its consolidated
subsidiaries, the assets of NiSource, other than the stock and assets of
Northern Indiana, are available as recourse for the benefit of Capital Markets'
creditors. The carrying value of the assets of NiSource, other than the assets
of Northern Indiana, were approximately $3.2 billion at December 31, 1999.

                             SHORT-TERM BORROWINGS
- --------------------------------------------------------------------------------

NiSource and its subsidiaries may borrow under two five-year $100 million
revolving credit agreements that terminate on September 23, 2003 and two 364-day
$100 million revolving credit agreements that terminate on September 23, 2000.
The 364-day agreements may be extended at expiration for additional periods of
364 days. Under these agreements, funds are borrowed at a floating rate of
interest or, under certain circumstances, at a fixed rate of interest for
short-term periods. These agreements provide financing flexibility and may be
used to support the issuance of commercial paper. At December 31, 1999, there
were no borrowings outstanding under these agreements.

   In addition, various NiSource subsidiaries maintain lines of credit for up to
an aggregate of $199.9 million with lenders at either the lender's commercial
prime or market lending rates. As of December 31, 1999, there were $54.1 million
of borrowings outstanding under these lines of credit with a weighted average
interest rate of 6.06%. As of December 31, 1998, there were $84.1 million of
borrowings outstanding under these lines of credit.

   NiSource and its subsidiaries maintain market lines of credit for up to
$394.4 million. As of December 31, 1999, there were $156.2 million outstanding
under these money market lines of credit with a weighted average interest rate
of 6.78%. At December 31, 1998, there were $127.3 million of borrowings
outstanding under these money market lines of credit.

   In September 1999, Capital Markets issued $160 million PURS in an
underwritten public offering. The PURS are unsecured debentures of Capital
Markets and rank equally with all other unsecured and unsubordinated debt of
Capital Markets. The PURS are subject to a call option under which the
underwriters may purchase all of the outstanding PURS from the holders on
September 28, 2000. The net proceeds from the sale of the PURS and the call
option of $162.4 million were used to refinance short-term indebtedness incurred
in connection with the acquisition of BSG in February 1999. Until September 28,
2000, the PURS will accrue interest at a rate based on LIBOR plus 1.25%. On
September 28, 2000, if the underwriters do not exercise their call option,
Capital Markets will be obligated to repurchase all of the outstanding PURS. If
the underwriters purchase all of the outstanding PURS pursuant to their call
option, the interest rate will be reset to a fixed rate based on then current
market rates plus a fixed margin and the PURS will remain outstanding until
2010.

CORPORATE PREMIUM INCOME EQUITY SECURITIES AND COMPANY-OBLIGATED MANDATORILY
REDEEMABLE PREFERRED SECURITIES OF TRUST HOLDING SOLELY COMPANY DEBENTURES
In February 1999 NiSource completed an underwritten public offering of Corporate
PIES. The net proceeds of approximately $334.7 million were primarily used to
fund the cash portion of the consideration payable in the acquisition of BSG,
and to repay short-term indebtedness.

     The Corporate PIES were offered as one unit comprised of two separable
instruments. The first component consists of stock purchase contracts to
purchase, four years from the date of issuance, common shares at a face value of
$50. The second component consists of mandatorily redeemable preferred
securities (Preferred Securities) which represent an undivided beneficial
ownership ~interest in the assets of NIPSCO Capital Trust I (Capital Trust). The
Preferred Securities have a stated liquidation amount of $50. The sole assets of
Capital Trust are subordinated debentures (Debentures) of Capital Markets that
earn interest at the same rates as the Preferred Securities to which they
relate, and certain rights under related guarantees by Capital Markets. The
Preferred Securities have been pledged to secure the holders' obligation to
purchase common shares under the stock purchase contracts.

     The face value of the stock purchase contracts is not recorded in the
Consolidated Balance Sheet. A $22.2 million present value contract fee payable
to the stock purchase contract holders has been recorded as a liability and as
reduction to paid-in capital. In addition, paid-in capital has been reduced by
$10.4 million for the issuance costs of the stock purchase contracts.

     The distributions paid on Preferred Securities are presented under the
caption "minority interests" in NiSource's Consolidated Statements of Income.
The amounts outstanding are presented under the caption, "Company-obligated
mandatorily redeemable preferred securities of subsidiary trust holding solely
company debentures," in NiSource's Consolidated Balance Sheet. At December 31,
1999, there were 6.9 million 5.9% Preferred Securities outstanding with Capital
Trust assets of $345 million.

NiSource expects that approximately $1.6 billion will be expended for
construction purposes for the period from January 1, 2000 to December 31, 2004.
Substantial commitments have been made in connection with this construction
program.

     Northern Indiana has entered into a service agreement with Pure Air, a
general partnership between Air Products and Chemicals, Inc. and Mitsubishi
Heavy Industries

America, Inc., under which Pure Air provides scrubber services to reduce sulfur
dioxide emissions for Units 7 and 8 at Bailly Generating Station. Services under
this contract commenced on June 15, 1992 with annual charges approximating $20
million. The agreement provides that, assuming various performance standards are
met by Pure Air, a termination payment would be due if Northern Indiana
terminates the agreement prior to the end of the twenty-year contract period.

     A ten-year agreement to outsource all data center, application development
and maintenance, and desktop management expires in 2005. Annual fees under the
agreement are approximately $20 million.

     Primary Energy, Inc. ("Primary") arranges energy-related projects for large
energy-intensive customers and offers such customers nationwide expertise in
managing the engineering, construction, operation and maintenance of such
projects. Through its subsidiaries, Primary has entered into agreements with
several of NiSource's largest industrial customers, principally steel mills and
a refinery, to service a portion of their energy needs. In order to serves its
customers under the agreements, Primary, through its subsidiaries, has entered
into certain operating lease commitments to lease these energy-related projects
which have a combined capacity of 393 megawatts. NiSource, principally through
Capital Markets, guarantees certain of Primary's obligations under each lease,
which are included in the Operating Leases.

     Primary has advanced approximately $36.6 million and $31.8 million, at
December 31, 1999 and December 31, 1998, respectively, to the lessors of the
energy-related projects discussed above. These net advances are included in
"Other Receivables" in the Consolidated Balance Sheet and as a component of
operating activities in the Consolidated Statement of Cash Flows.

                           RISK MANAGEMENT ACTIVITIES
- --------------------------------------------------------------------------------

     NiSource uses certain commodity-based derivative financial instruments to
manage certain risks inherent in its business. NiSource's senior management
takes an active role in the risk management process and has developed policies
and procedures that require specific administrative and business functions to
assist in the identification, assessment and control of various risks. The open
positions resulting from risk management activities are managed in accordance
with strict policies which limit exposure to market risk and require daily
reporting to management of potential financial exposure.

     NiSource uses futures contracts, options and swaps to hedge a portion of
its price risk associated with its non-trading activities in gas supply for its
regulated gas utilities, certain customer choice programs for residential
customers and other retail customer activity. At December 31, 1999, NiSource had
futures contracts representing the hedge of natural gas sales in the notional
amount of 8.0 billion cubic feet (BCF) resulting in a deferred gain of $0.9
million.

     NiSource's trading operations includes the activities of its power trading
business and non-affiliated transactions associated with TPC. NiSource employs a
VaR model to assess the market risk of its energy trading portfolios. NiSource
estimates the one-day VaR for both trading groups which utilize derivatives
using either a Monte Carlo simulation or variance/covariance at a 95 percent
confidence level. Based on the results of the VaR analysis, the daily market
exposure for power trading on an average, high and low basis was $0.4, $1.2 and
$0.014 million during 1999, respectively. The daily VaR for the gas trading
portfolio on an average, high and low basis was $1.3, $2.1 and $0.4 million
during 1999, respectively. There were no significant trading positions during
1998.

     Unrealized gains and losses on our portfolio are recorded as price risk
management assets and liabilities. The market prices used to value price risk
management activities reflect the best estimate of market prices considering
various factors, including closing exchange and over-the-counter quotations and
price volatility factors underlying the commitments. The accompanying financial
statements reflect price risk management assets and liabilities (including net
option premiums) of $32 million and $54 million at December 31, 1999. Power
trading results are reflected on a net basis in the accompanying statement of
income, consistent with the guidance in EITF Issue No. 98-10 with respect to the
use of written options. NiSource has recorded a net profit of $11 million as a
component of electric revenues for the year ended December 31, 1999. Activities
with respect to gas trading are reflected on a gross basis with revenues and
cost of goods sold consistent with the physical nature of the trades. NiSource
has recorded gas trading revenues and cost of goods sold of approximately $365
million and $371 million, respectively for the year ended December 31, 1999.

- --------------------------------------------------------------------------------
                      FAIR VALUE OF FINANCIAL INSTRUMENTS
- --------------------------------------------------------------------------------

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which it is practicable to estimate fair
value:

CASH AND CASH EQUIVALENTS
The carrying amount approximates fair value due to the short maturity of those
instruments.

INVESTMENTS
Where feasible, the fair value of investments is estimated based on market
prices for those or similar investments.

================================================================================

LONG-TERM DEBT/PREFERRED STOCK AND PREFERRED SECURITIES
The fair values of these securities are estimated based on the quoted market
prices for the same or similar issues or on the rates offered for securities of
the same remaining maturities. Certain premium costs associated with the early
settlement of long-term debt are not taken into consideration in determining
fair value.

   A substantial portion of the long-term debt relates to utility operations.
The Utilities are subject to regulation and gains or losses may be included in
rates over a prescribed amortization period, if in fact settled at amounts
approximating those above.

The Utilities supply natural gas, electric energy and water. Natural gas and
electric energy are supplied to the northern third of Indiana and portions of
Massachusetts, New Hampshire and Maine. The Water Utilities serve Indianapolis,
Indiana, and surrounding areas. Although the Energy Utilities have a diversified
base of residential and commercial customers, a substantial portion of their
electric and gas industrial deliveries are dependent upon the basic steel
industry. The following table shows the basic steel industry percentage of gas
revenue (including transportation services) and electric revenue for 1999, 1998

(a) Because of the combined mathematical effect of common shares repurchased and
    issued and the cyclical nature of net income during the year, the sum of
    earnings per share data for any four quarterly periods may vary slightly
    from the earnings per share data for the equivalent twelve-month period.

                              SEGMENTS OF BUSINESS
- --------------------------------------------------------------------------------
Operating segments are defined as components of an enterprise for which separate
financial information is available and is evaluated regularly by the chief
operating decision maker in deciding how to allocate resources and in assessing
performance.

   There are four reportable operating segments: Gas, Electric, Water and Gas
Marketing. The Gas segment includes regulated gas utilities which provide
natural gas distribution and transportation services. The Electric segment is
comprised principally of Northern Indiana, a regulated electric utility, which
generates, transmits and distributes electricity. In addition, the Electric
segment includes wholesale power marketing and trading operation which markets
wholesale power to other utilities and electric power marketers. The Water
segment includes regulated water utilities which provide distribution of water
supply to the public. The Gas Marketing segment provides natural gas marketing,
trading, storage and sales to wholesale and industrial customers.

   Reportable segments are operations that are managed separately and meet
certain quantitative thresholds. The Other Products and Services column includes
a variety of businesses, such as installation, repair and maintenance of
underground pipelines, utility line locating and marking, the arrangement of
energy-related projects for large energy-intensive facilities, and other
products and services, which collectively do not constitute a segment for
reporting purposes.

   Revenues for each segment are principally attributable to customers in the
United States. Additional revenues, which are insignificant to consolidated
revenues, are attributable to customers in Canada and the United Kingdom.

   The following tables provide information about business segments. NiSource
uses income before interest and income taxes as its primary measurement for each
of the reported segments. NiSource makes decisions on finance, dividends and
taxes at the corporate level. These topics are addressed on a consolidated
basis. In addition, adjustments have been made to the segment information to
arrive at information included in the results of operations and financial
position. These adjustments include unallocated corporate assets, revenues and
expenses and the elimination of intercompany transactions. The accounting
policies of the operating segments are the same as those described in "Summary
of Significant Accounting Policies."
