FORWARD-LOOKING INFORMATION
- ---------------------------
 
Certain matters discussed in this Annual Report on Form 10-K for Consolidated
Natural Gas Company and its subsidiaries (the Company) are "forward-looking
statements" intended to qualify for the safe harbors from liability
established by the Private Securities Litigation Reform Act of 1995. These
forward-looking statements can generally be identified as such because the
context of the statement will include words such as the Company "believes,"
"anticipates," "expects" or words of similar import. Similarly, statements
that describe the Company's future plans, objectives or goals are also
forward-looking statements. Such statements may address future events and
conditions concerning capital expenditures, earnings, litigation, rate and
other regulatory matters, liquidity and capital resources, and financial
accounting matters. Actual results in each instance could differ materially
from those currently anticipated in such statements, due to factors such as:
natural gas and electric industry restructuring, including ongoing state and
federal activities; the weather; demographics; general economic conditions and
specific economic conditions in the Company's distribution service areas;
developments in the legislative, regulatory and competitive markets in which
the Company operates; and other circumstances affecting anticipated revenues
and costs.

The principal cities served at retail by the gas distribution subsidiaries
(East Ohio Gas, West Ohio Gas, Peoples Natural Gas, Virginia Natural Gas and
Hope Gas) are: Cleveland, Akron, Youngstown, Canton, Warren, Lima, Ashtabula
and Marietta in Ohio; Pittsburgh (a portion), Altoona and Johnstown in
Pennsylvania; Norfolk, Newport News, Virginia Beach, Chesapeake, Hampton and
Williamsburg in Virginia; and Clarksburg and Parkersburg in West Virginia. At
December 31, 1996, the Company served at retail approximately 1,841,000
residential, commercial and industrial gas sales customers in Ohio,
Pennsylvania, Virginia and West Virginia. Variations in weather conditions can
materially affect the volume of gas delivered by the distribution
subsidiaries, as 98 percent of their residential and commercial customers use
gas for space heating.
 
CNG Transmission is an interstate gas transmission subsidiary that operates a
regional interstate pipeline system serving each of the distribution
subsidiaries, and nonaffiliated utility and end-user customers in the Midwest,
the Mid-Atlantic states and the Northeast. Through its wholly owned
subsidiary, CNG Iroquois, Inc., CNG Transmission holds a 16 percent general
partnership interest in the Iroquois Gas

ITEM 1.  BUSINESS (Continued)

Transmission System, L.P., a Delaware limited partnership that owns and
operates an interstate natural gas pipeline extending from the Canada-United
States border near Iroquois, Ontario, to Long Island, New York. The Iroquois
pipeline transports Canadian gas to utility and power generation customers in
metropolitan New York and New England.
 
CNG Producing is a gas and oil exploration and production subsidiary whose
activities are conducted primarily in the Gulf of Mexico, the southern and
western United States, the Appalachian region, and in Canada.
 
CNG Energy Services is a nonregulated energy marketing subsidiary that markets
Company-owned gas production and offers an array of gas sales, transportation,
storage and other services that can be arranged separately or in various
combinations to meet the individual energy needs of customers. CNG Energy
Services also holds the Company's ownership interests in seven independent
power plants, including a 34% limited partnership interest in Lakewood
Cogeneration, L.P. (Lakewood Partnership), which operates a 237-megawatt
cogeneration facility in Lakewood, New Jersey.
 
CNG Power Services is a power marketing subsidiary with Federal Energy
Regulatory Commission (FERC) approval to purchase and resell electricity at
market-based rates. CNG Power Services also owns a 1% general partnership
interest in the Lakewood Partnership.
 
CNG International was formed in 1996 to engage in energy-related activities
outside of the United States. CNG International holds a 30 percent ownership
interest in Epic Energy Pty Ltd. (Epic Energy), an Australian entity that owns
and operates two major long-distance natural gas pipelines in Australia.
 
Consolidated LNG was organized to import and regasify liquefied natural gas
(LNG) for sale to CNG Transmission. However, Consolidated LNG ended its
involvement in LNG operations in 1982 and is currently recovering its
undepreciated investment in LNG-related facilities, plus carrying charges and
taxes, through a FERC-approved amortization surcharge.
 
CNG Research administers proprietary research activities. Amounts spent on
research activities in the calendar years 1994 through 1996 by all the
subsidiaries were not material.
 
CNG Coal formerly owned coal reserves and a related plant site. In 1995, the
Company recognized a pretax charge of $31.3 million in connection with a
write-down of the value of these coal properties. In July 1996, CNG Coal
completed the sale of its properties to a subsidiary of Cyprus Amax Minerals
Company.
 
Service Company is a subsidiary service company, authorized by the Securities
and Exchange Commission (SEC) under the PUHCA. It advises and assists the
other subsidiary companies on administrative and technical matters and manages
centralized activities and facilities for their benefit. It also provides
services to the Parent Company.
 
CNG Financial was formed to engage in financing of gas-utilizing equipment,
but has not yet engaged in any such transactions.
 
GOVERNMENTAL REGULATION
 
The Company is subject to regulation by the SEC pursuant to the PUHCA. After
an in-depth study of the PUHCA in the context of fundamental changes in the
energy industry over the past decade, the SEC's Division of Investment
Management issued a report in 1995 on the regulation of public utility holding
companies. This report contains recommendations for legislative action,
including repeal of the PUHCA with more oversight responsibility borne by the
FERC and state commissions. The report also proposes reform to remove a
substantial portion of the administrative burden inherent in the current PUHCA
regulatory policies and procedures. The SEC initiated action in 1995 to
implement such reform. In addition, legislation for the repeal of the PUHCA
was introduced in Congress during 1996, but was not enacted. Legislation for
repeal of the PUHCA in connection with electric industry deregulation (see
"Gas
 
                                       3
<PAGE>
 
ITEM 1.  BUSINESS (Continued)

and Electric Industry Developments," page 5) has been introduced again in
Congress in 1997, and it is anticipated that federal legislation for stand-
alone repeal will be introduced again during 1997.
 
CNG Transmission and Consolidated LNG are "natural-gas companies" subject to
the Natural Gas Act of 1938, as amended. CNG Transmission's interstate
transportation and storage activities are regulated under such Act and are
conducted in accordance with tariffs and service agreements on file with the
FERC. CNG Energy Services and CNG Power Services, public utilities as defined
by section 201 of the Federal Power Act, are also subject to limited FERC
regulation. The distribution subsidiaries are subject to regulation by the
respective utility commissions in the states within which they operate.
 
Certain subsidiaries are subject to various provisions of the five statutes
which are referred to as the National Energy Act of 1978. One of these
statutes, the National Energy Conservation Policy Act, requires utilities to
offer home energy audits and other assistance to residential customers.
 
The Natural Gas Pipeline Safety Act of 1968 (which, among other things,
authorizes the establishment and enforcement of federal pipeline safety
standards) subjects the interstate pipeline of CNG Transmission to the safety
jurisdiction of the Department of Transportation. Intrastate facilities remain
within the safety jurisdiction of the state regulatory agencies, presuming
compliance by such agencies with certain prerequisites contained in such Act.
 
The Company is subject to the provisions of various federal laws dealing with
the protection of the environment. CNG Transmission and certain of the
distribution subsidiaries are subject to the Federal Clean Air Act (Clean Air
Act) and the Federal Clean Air Act Amendments of 1990 which added
significantly to the existing requirements established by the Clean Air Act.
In addition, the subsidiary companies are subject to the environmental laws
and regulations of state and local governmental authorities in the areas
within which the subsidiaries have operations or facilities.
 
CAPITAL EXPENDITURES
 
The current capital spending program for 1997 is estimated at $525.9 million,
a 6.1 percent decrease compared with total capital spending in 1996. The
estimated 1997 budget has been allocated as follows: distribution, $150.3
million; transmission, $82.7 million; exploration and production, $231.4
million; energy marketing services, $5.6 million; and corporate and other,
$55.9 million. The decreased level of capital expenditures anticipated for
1997 assumes slightly lower spending for exploration and production
operations, reflecting reduced spending on deep-water projects and increased
conventional drilling, both onshore and offshore. Transmission and
distribution operations expenditures will primarily be limited to spending for
enhancements and improvements in the pipeline system and related facilities.
The "corporate and other" category includes expenditures to upgrade
information systems technology, primarily to centralize and consolidate
services and financial systems, and to invest in selected international
projects. The capital budget will be reviewed during the year and is subject
to revision.
 
COMPETITIVE CONDITIONS
 
Various regulatory and market trends have combined to increase competition for
the Company in recent years, and for the gas industry in general. The factors
affecting the Company include: regulatory efforts, such as the FERC's various
initiatives to increase competition in the industry; the overall availability
of gas nationwide at relatively low prices; competition from producers and
other sellers and brokers of gas for the retail and wholesale markets;
expansion of competition among distribution companies for industrial and
commercial customers; competition with existing and proposed pipelines, and
projects to import gas from Canada and other foreign countries; and
competition with other energy forms, such as electricity, fuel oil and coal.

ITEM 1.  BUSINESS (Continued)
 
   RESTRUCTURING OF INTERSTATE PIPELINE INDUSTRY
 
FERC Order 636 has significantly increased competition in the natural gas
industry. In the restructured marketplace, local gas utilities and large-
volume end users, including former pipeline sales customers, bear all the
responsibilities and risks for arranging the procurement of their gas supplies
and contracting with pipelines to transport purchases.
 
The restructuring of the interstate natural gas pipeline industry has also
affected the distribution subsidiaries. Industrial and large commercial gas
users now purchase a large portion of their gas supplies directly from
producers, from marketers, or on the spot market. However, the distribution
subsidiaries have, for the most part, been able to retain these customers by
providing transportation service for such supplies. The most significant
effect on local distribution companies of Order 636 has been on their gas
supply procurement and storage practices, as these companies now bear all the
responsibilities and risks for arranging the acquisition, delivery and storage
of their own gas supplies. However, as the distribution subsidiaries have been
managing a part of their own gas supplies for a number of years, the
transition to the more competitive environment under Order 636 did not have a
significant impact on their operations. Storage facilities owned and operated
by the distribution and transmission operations as well as storage capacity
acquired have become even more important factors in gas supply management.
 
Gas producers throughout the industry, including CNG Producing, are faced with
a more diverse and active market with purchasers seeking to balance the
advantage of lower-cost spot market supplies with the security of higher-
priced, longer-term contracts. The presence of gas and energy marketing firms
has added to the competition for CNG Producing. As a result, CNG Energy
Services has been the primary marketing agent for all of the Company's
nonregulated gas production since January 1, 1995 (see "Energy Marketing
Services," page 8).
 
   GAS AND ELECTRIC INDUSTRY DEVELOPMENTS
 
In the post-Order 636 gas industry environment, competition at the retail
level is receiving increased attention by state regulators. Several states
have commenced proceedings to evaluate restructuring of the natural gas
industry at the retail level. These proceedings have generally focused on
unbundling, incentive ratemaking, market-based rates and customer choice (see
"Retail Unbundling," page 14).
 
In addition to the further deregulation of the gas industry, the emerging
unbundling of services provided by electric utilities may ultimately result in
the convergence of both industries to create one overall, highly competitive
marketplace for a customer's total energy needs. During 1995 and 1996,
regulators at the federal and state levels finalized initiatives to promote
increased competition in the electric industry. These initiatives included
issuance in April 1996 of FERC Order Nos. 888 and 889 (Orders 888 and 889). By
requiring open access to the national electric transmission grid, Order 888
fosters increased competition in both the generation of electricity and the
supply of bulk power to major wholesale customers. A companion order, Order
889, addresses the timing, information access and other administrative details
associated with the FERC deregulation initiative. Other signs of an
increasingly deregulated electric utility environment include retail
competition plans adopted in several states, pilot retail wheeling programs
and pro-competition legislation proposed at both the federal and state levels.
 
Reflecting the evolution to a more competitive energy environment, the pace
and size of business combinations among natural gas and electric utilities
increased significantly during 1996. These business combinations have
generally been initiated to provide benefits from economies of scale, to
reduce costs by the elimination of duplicate facilities and processes, and to
improve the strategic and competitive position of the surviving entity. Recent
and pending regulatory actions may serve to further facilitate more business
combinations in the energy industry. The FERC has streamlined its regulatory
review process regarding pending mergers. In addition, the SEC has recommended
legislation to conditionally repeal the PUHCA, to which the Company is
subject, in conjunction with legislation which would grant the various
 
                                       5
<PAGE>
 
ITEM 1.  BUSINESS (Continued)
 
state regulatory commissions greater oversight authority of companies
currently subject to the PUHCA. If legislation to repeal or significantly
modify the provisions of the PUHCA becomes law, certain restrictions related
to diversification activities, including business combinations, for gas and
electric companies subject to the PUHCA may be eased.
 
Through its actions in recent years, the Company believes it is well-
positioned to compete in an evolving and increasingly deregulated energy
marketplace. The creation in 1997 of CNG Retail Services Corporation and the
ongoing development of the energy marketing services component, in conjunction
with streamlining and restructuring of its existing distribution, transmission
and exploration and production operations, reflects the Company's proactive
approach to meeting the demands of a more competitive and dynamic business
environment.
 
   DISTRIBUTION
 
The distribution subsidiaries generally operate in long-established service
areas and have extensive facilities already in place. Growth in the Company's
traditional service areas in Ohio, Pennsylvania and West Virginia is limited
in that natural gas is already the fuel of choice for heating and for most
significant industrial applications. These areas have experienced minimal
population growth in recent years, and almost all customers have become more
energy efficient, resulting in lower gas usage per customer. In addition, the
economies of these areas, which were formerly based mainly on heavy industry,
have diversified with increased emphasis on high technology and service
oriented firms.
 
However, opportunities for growth in the distribution operations are expected
to continue at Virginia Natural Gas. This subsidiary offers the potential for
future growth through its expanding service territory and the prospect of
conversion of space-heating customers and commercial and industrial
applications to gas. The completion in 1992 of the intrastate pipeline in
Virginia has provided Virginia Natural Gas and its customers with new gas
supply sources through access to the Company's transmission and storage
facilities, and has afforded additional opportunities for growth in both gas
sales and transportation, especially in the power generation markets.
 
The Clean Air Act may also provide opportunities for increased throughput in
the Company's distribution markets. The Company is promoting the use of
natural gas as a means for industrial customers and electric generators to
reduce emissions. The Clean Air Act and the more recent Energy Policy Act of
1992 contain a number of provisions relating to the use of alternative fuel
vehicles. The Company is participating in various programs to demonstrate the
advantages and environmental benefits of natural gas powered vehicles.
 
Competition in the markets served by the distribution subsidiaries continues
to increase. As the gas industry has restructured and government regulations
have changed, a marketplace has evolved with new and traditional competitors--
the usual oil and electric companies, other gas companies, producers seeking
to gain direct access to the Company's customers, and gas brokers and dealers
seeking to supplant supplies with spot market gas. Natural gas faces price
competition with other energy forms, and certain of the distribution
companies' industrial customers have the ability to switch to fuel oil or coal
if desired. In addition, competition is increasing among local distribution
companies to provide gas sales and transportation services to commercial and
residential customers (see "Retail Unbundling," page 14). Currently, local
distribution companies operate in what are essentially dual markets--a
traditional utility market, where a utility has an obligation to provide
service and offers a "bundled" package of services to all customers; and a
"contract" market, where obligations are defined by contract terms and large
customers can elect individually or in various combinations whatever gas
supplies, storage and/or transportation services they require. The Company has
responded to this competitive environment by offering an expanded range of
services to its customers. The distribution subsidiaries routinely provide a
variety of firm and interruptible services, including gas transportation,
storage, supply pooling and balancing, and brokering, to industrial and
commercial customers.

   TRANSMISSION
 
CNG Transmission operates a regional interstate pipeline system with the
principal pipeline and storage facilities located in Ohio, Pennsylvania, West
Virginia and New York. CNG Transmission offers gas transportation, storage and
related services to its affiliates, as well as to utilities and end users in
the Northeast, Mid-Atlantic and Midwest regions of the country.
 
The changing regulatory environment has provided CNG Transmission and other
pipeline companies with unique opportunities for expansion. CNG Transmission
has taken advantage of selected market expansion opportunities, concentrating
its efforts primarily in the Northeast and along the East Coast. CNG
Transmission's large underground storage capacity and the location of its
gridlike pipeline system as a link between the country's major gas pipelines
and large markets on the East Coast have been key factors in the success of
these expansion efforts. The Company's pipelines are part of an interconnected
gas transmission system which will enable retail end users to take advantage
of the accessibility of supplies nationwide in the evolving deregulation of
the gas industry at the retail level (see "Gas and Electric Industry
Developments," page 5 and "Retail Unbundling," page 14). In addition, such a
network allows the Company to manage its gas supply requirements in an
efficient and flexible manner.
 
CNG Transmission competes with domestic as well as Canadian pipeline companies
and gas marketers seeking to provide or arrange transportation, storage and
other services for customers. Also, certain end users have the ability to
switch to fuel oil or coal if desired. Although competition is based primarily
on price, the range of services that can be provided to customers is also an
important factor. The combination of capacity rights held on certain longline
pipelines, a large storage capability and the availability of numerous receipt
and delivery points along its own pipeline system, enables CNG Transmission to
tailor its services to meet the individual needs of customers.
 
   EXPLORATION AND PRODUCTION
 
Exploration and production operations are conducted by CNG Producing in
several of the major gas and oil producing basins in the United States, both
onshore and offshore. In this highly competitive business, the Company
competes with a large number of entities ranging in size from large
international oil companies with extensive financial resources to small, cash
flow-driven independent producers.
 
CNG Producing faces significant competition in the bidding for federal
offshore leases and in obtaining leases and drilling rights for onshore
properties. Since CNG Producing is the operator of a number of properties, it
also faces competition in securing drilling equipment and supplies for
exploration and development. From the production perspective, the marketing of
gas and oil is highly competitive with price being the most significant
factor. Effective January 1, 1995, CNG Energy Services became the primary
marketing agent for all of the Company's nonregulated gas production. When the
economics warrant, the Company attempts to sell its gas production under long-
term contracts to customers such as electric power generators and others that
require a secure source of supply. However, these arrangements represent only
a portion of the Company's gas production. Further, the deliverability of gas
produced is also influenced by competition for downstream pipeline
transportation capacity. In response to the unbundling of sales services
previously offered by pipelines, CNG Producing and CNG Energy Services have
taken actions to expand and diversify the Company's customer base. CNG Energy
Services continues to develop new marketing strategies and contracts to
address customer needs for intermediate and long-term gas supplies as well as
other energy services.
 
The exploration for and production of gas and oil is subject to various
federal and state laws and regulations which may, among other things, limit
well drilling activity and volumes produced. Changes in these laws and
regulations can impact the exploration and production operations.

   ENERGY MARKETING SERVICES
 
The Company's energy marketing services operations, comprised of CNG Energy
Services and CNG Power Services, are engaged in a variety of energy-related
activities in highly competitive markets. These activities, which are under a
single management team, include fuel management, gas trading, energy price
risk management, pipeline capacity and storage management, power marketing and
electric generation.
 
Energy marketing services competes with the marketing operations of both
independent and major energy companies in addition to electric utilities,
independent power producers, local distribution companies, and various energy
brokers. As a result of the continuing efforts to deregulate both natural gas
and electric utility operations, the economic differences among different
forms of energy are expected to be reduced in the future. Competition is based
largely upon pricing, availability and reliability of supply, technical and
financial capabilities, regional presence and international experience.
 
GAS SUPPLY
 
   GENERAL INFORMATION
 
The Company's gas supply is obtained from various sources including: purchases
from major and independent producers in the Southwest and Midwest regions;
purchases from local producers in the Appalachian area; purchases from gas
marketers; purchases on the spot market; production from Company-owned wells
in the Appalachian area, the Southwest, and the Midwest; and withdrawals from
the Company's underground storage fields.
 
Regulatory actions, economic factors, and changes in customers and their
preferences continue to reshape the Company's gas sales markets. A significant
number of industrial customers and many commercial customers currently
purchase a large portion of their gas supplies from producers, marketers, or
on the spot market, and contract with the transmission and distribution
subsidiaries for transportation and other services. Since these customers are
less reliant on the distribution subsidiaries for sales service, the volume of
gas that these subsidiaries must obtain to meet sales requirements has been
reduced. This trend is likely to continue as the state regulatory environment
proceeds towards unbundling of services at the retail level. The distribution
subsidiaries and CNG Energy Services have the responsibility and risk for
obtaining their own gas supplies.
 
The Company's available gas supply in 1996 was again in a surplus position--
where available supplies exceed sales requirements. Considering the Company's
large storage capacity, the volumes obtainable under its gas purchase and gas
supply contracts, Company-owned gas reserves, and assuming the future
availability of spot market gas, the Company believes that supplies will be
available to meet sales requirements for several years. Gas supply statistics
for the past five years are on page 13.
 
   GAS PURCHASED
 
Purchased gas volumes were 618.3 billion cubic feet (Bcf) in 1996,
representing 83 percent of the Company's total 1996 gas supply of 744.5 Bcf.
Spot market and short-term purchases were 553.4 Bcf, or about 74 percent of
the total 1996 supply. Volumes purchased under contracts with Appalachian area
producers totaled 64.9 Bcf, or 9 percent of the 1996 supply.
 
While spot market gas supplies have historically been obtained at lower
prices, the availability and price of such supplies to distribution companies
can be severely impacted by market swings in supply and demand, often due to
sudden changes in weather conditions. The distribution subsidiaries must weigh
the benefits of generally lower-cost spot market purchases with the security
of longer-term contract arrangements. To ensure a secure supply, the
distribution subsidiaries have purchased a larger portion of
 
                                       8
<PAGE>
 
ITEM 1.  BUSINESS (Continued)
 
their gas supplies directly from producers on a firm basis. However, spot
market gas will continue to be part of the Company's supply mix, particularly
for CNG Energy Services.
 
Gas purchased from producers and on the spot market is delivered to the
distribution subsidiaries using the firm transport capacity contracted for on
interstate pipelines. At December 31, 1996, the subsidiaries had 365 Bcf of
firm transport capacity to move supplies from purchase locations to market,
yielding deliveries of up to 1.0 Bcf of gas a day. These pipelines include CNG
Transmission, Tennessee Gas Pipeline Company, Panhandle Eastern Pipe Line
Company, Texas Eastern Transmission Corporation, ANR Pipeline Company, Texas
Gas Transmission Corporation, Transcontinental Gas Pipe Line Corporation and
Columbia Gas Transmission Corporation. CNG Energy Services also uses firm
transportation capacity to receive supplies from producers and make deliveries
to customers.
 
   GAS STORAGE
 
The Company's underground storage complex plays an important part in balancing
gas supply with sales demand and is essential to servicing the Company's large
volume of space-heating business. In addition, storage capacity is an
important element in the effective management of both gas supply and pipeline
transport capacity. The Company operates 26 underground gas storage fields
located in Ohio, Pennsylvania, West Virginia and New York. The Company owns 21
of these storage fields and has joint-ownership with other companies in 5 of
the fields. The total designed capacity of the storage fields is approximately
885 Bcf. The Company's share of the total capacity is about 669 Bcf. About
one-half of the total capacity is base gas which remains in the reservoirs at
all times to provide the primary pressure which enables the balance of the gas
to be withdrawn as needed.
 
CNG Transmission operates 719 Bcf of the total designed storage capacity and
owns 503 Bcf of the Company's capacity. CNG Transmission utilizes a large
portion of its turnable capacity to provide approximately 252 Bcf of gas
storage service for others. This service is provided principally to other
pipelines and nonaffiliated utilities whose primary service areas are along
the East Coast. CNG Transmission also provides storage service to affiliates,
end users and to many of its former wholesale gas sales customers.
 
Two of the distribution subsidiaries, East Ohio Gas and Peoples Natural Gas,
own and operate the remaining 166 Bcf of storage capacity. In addition to
owning their own storage, these companies, as well as most of the other
subsidiaries, have ready access to a portion of the storage capacity operated
by CNG Transmission. The distribution subsidiaries and CNG Energy Services
also have capacity available in storage fields owned by others.
 
The Company controls other acreage in the Appalachian area suitable for the
development of additional storage facilities which would enable further
expansion of capacity to meet possible future storage needs.
 
   GAS AND OIL PRODUCING ACTIVITIES
 
After experiencing several years of adverse conditions in the industry, the
exploration and production operations posted a significant turnaround during
1996, boosted by higher gas and oil wellhead prices and increased production.
While the Company's 1997 capital spending program for exploration and
production operations is expected to be lower than 1996 spending, the
Company's long-range capital planning budget provides for additional amounts
for project-specific expenditures in this business segment, if and when
needed. Part of the Company's strategy for its exploration and production
operations is to further balance offshore and onshore production, and to
increase the oil portion of total production.
 
The Company's gas wellhead prices in 1996 averaged $2.46 a thousand cubic feet
(Mcf), up from $1.89 in 1995. Consistent with prices nationwide, the Company's
gas wellhead prices in 1996 were above prior
 
                                       9
<PAGE>
 
ITEM 1.  BUSINESS (Continued)

year levels for most of the period. The Company's average gas wellhead prices
are generally higher and less volatile than industry spot prices since its
average price reflects a mix of longer-term contracts. However, due to market-
based pricing mechanisms under many of the contracts, the Company's gas prices
generally follow industry trends. The average oil wellhead price in 1996
increased to $17.60 a barrel, compared with $16.04 in 1995, consistent with
the general increase in world oil prices.
 
The Company's total gas production in 1996 was 147.5 Bcf, up from 107.2 Bcf in
1995. Oil production was 4.8 million barrels, up 51 percent from 3.1 million
barrels in 1995.
 
During 1996, CNG Producing participated in the drilling of 152 gross wells (43
net), compared with 53 gross wells (26 net) drilled in 1995. The following
table sets forth 1996 drilling activity by region:

</TABLE>
 
Of the total 152 wells drilled in 1996, 137 were successful, a 90 percent
success rate. Of the 20 exploratory wells drilled, 8 were successful. In
response to market conditions, the Company increased its drilling activity
during 1996 in connection with an enhanced oil recovery program in Alberta,
Canada.
 
Total Company-owned proved gas reserves at year-end were 1,083 Bcf, up from
1,041 Bcf at the end of 1995. Proved oil reserves were 50.5 million barrels,
compared with 45.8 million barrels in 1995. CNG added 272 Bcf of gas
equivalent from additions, revisions, and purchases of gas and oil reserves in
1996 (See "Company-Owned Reserves," page 20). During 1996, major discoveries
were made in the Main Pass and West Cameron areas of the Gulf of Mexico, and
reserves equivalent to 47 Bcf of natural gas were acquired in Utah.
 
Natural gas production began in January 1996 at Popeye, a deep-water natural
gas discovery in the Green Canyon area of the Gulf of Mexico. The field is
producing over 140 million cubic feet of gas per day from two wells flowing
through a state of the art subsea facility developed to produce gas 2,000 feet
below sea level. The Company's portion of production from this field was the
equivalent of 28 Bcf of gas during 1996, including 1.1 million barrels of
condensate. CNG Producing's interest in this property is 37.5 percent. Shell
Offshore, Inc. is the operator in the joint venture and Mobil Oil Exploration
and Producing Southeast and BP Exploration Inc. are the other participants.
 
Production began in the first quarter of 1997 at Neptune, a deep-water oil
discovery at Viosca Knoll 826. This project, in which the Company holds a 50
percent interest, added proved reserves equivalent to 190 Bcf of gas in 1994,
representing the largest single addition to the Company's reserves in its
history. Additional proved reserves at Neptune equivalent to 18 Bcf of gas
were added during 1996. Facilities have been designed with Oryx Energy
Company, the operating partner, to produce up to 25,000 barrels of oil and 30
million cubic feet of natural gas a day. Neptune uses an innovative floating
production facility called a Spar, a 700-foot-long cylindrical structure that,
during 1996, was towed to the site, turned on end and anchored to the sea
floor with cables. This is the first time a Spar has been used in the Gulf of
Mexico to support a production platform.
 
Participation in the Popeye and Neptune projects has provided the Company
access to new technologies and the experience necessary to better evaluate
additional deep-water opportunities. Accordingly, the Company is evaluating a
deep-water prospect, Navarro, located in the Green Canyon area of the Gulf of
Mexico. This prospect is operated by the British-Borneo Petroleum Syndicate.
The Company expects to determine the commercial viability of this prospect by
the end of 1997.

ITEM 1.  BUSINESS (Continued)
 
The Company's gas gathering interests in the Gulf of Mexico are being expanded
as part of the merger of two undersea gathering systems. Effective December
31, 1996, Main Pass Gas Gathering Company (Main Pass), in which the Company
had a 33 1/3 percent ownership interest, was merged with Dauphin Island
Gathering System. Main Pass serves Company properties at Main Pass 223 and 225
and the Neptune project. The combined system, called Dauphin Island Gathering
Partners, is expected to be linked and expanded by adding 78 miles of 24-inch
pipe by the winter of 1997-98. The expansion will add 500 million cubic feet
of gas per day of capacity, bringing the total to 1.15 Bcf per day. CNG Energy
Services holds a 13.6 percent interest in the combined system. Other partners
are subsidiaries of PanEnergy Corp., MCN Corporation, Coastal Corporation and
Dauphin Island Gathering Company.
 
CNG Producing was the successful bidder on 5 leases offered in the federal
government's Gulf of Mexico lease sales in 1996, acquiring 5 blocks off the
coast of Louisiana. At year-end 1996, the Company held 2.0 million net acres
of exploration and production properties, approximately the same as year-end
1995. The Company's lease holdings include about 1.5 million net acres in the
Appalachian area, 328,600 in the offshore Gulf of Mexico, and 199,500 in the
inland areas of the Southwest, Gulf Coast and West. The Company holds a 21
percent interest in heavy oil properties in Alberta, Canada. Proved reserves
associated with the Canadian properties approximated 1 Bcf of gas and 8.6
million barrels of oil at December 31, 1996. On an energy-equivalent basis,
these reserves represent about 4 percent of the Company's total proved
reserves at that date.
 
The Company drilled 4 wells in the Appalachian Region during 1996. The Company
plans to continue production from these properties and to maintain its strong
acreage position in the Appalachian Region, and may seek to acquire additional
properties in this area that meet the Company's longer-term strategy.
 
The Company will continue to review its property inventory during 1997, and
sales of selected properties are possible depending on economic conditions.

Sales of gas to residential customers in 1996 were 219 Bcf, up 7 Bcf from
1995, while sales to commercial customers were 67 Bcf in 1996, down 3 Bcf
compared to 1995. Residential gas sales volumes increased as colder weather
during 1996 resulted in higher gas usage by space-heating customers. The
weather in the Company's retail service areas in 1996 was 5 percent colder
than 1995, and was 6 percent colder than normal. Residential and commercial
sales volumes also reflect the net

addition of about 17,000 customers in 1996. The decline in commercial sales
volumes reflects the conversion of certain customers to users of
transportation service.
 
Industrial sales in 1996 were 7 Bcf, consistent with 1995. Due to both
availability and price, many industrial users buy gas directly from producers,
from marketers, or on the spot market, and contract with the subsidiaries for
transportation service. Total gas deliveries (sales and transportation) to
industrial customers were 139 Bcf in 1996, compared with 138 Bcf in 1995.
 
   NONREGULATED SALES
 
Nonregulated gas sales in 1996 were 396 Bcf, down from 557 Bcf in 1995. Gas
sales by CNG Energy Services were 369 Bcf, compared to 523 Bcf in 1995.
Volumes related to gas brokering activity were 19 Bcf in 1996, down from 25
Bcf in 1995. Sales of Company-produced gas to nonaffiliates were 8 Bcf,
compared with 9 Bcf in 1995.
 
   GAS TRANSPORTATION
 
Total transportation volumes in 1996 were 758 Bcf, up from 750 Bcf in 1995.
Transportation during the first quarter of 1996 was up 10 percent compared to
the prior year quarter due in part to colder weather. Total transportation
volumes include volumes transported by the distribution subsidiaries for
commercial, industrial and off-system customers amounting to 174 Bcf in 1996,
up 9 Bcf over 1995. This increase reflects transportation volumes for
commercial customers which were up 7 Bcf compared to the prior year.

ITEM 1.  BUSINESS (Continued)

 
MARKET EXPANSION
 
In recent years the Company has pursued a broad program designed to expand its
interstate pipeline system and extend its marketing territory. The Company's
principal objective has been to build long-term supply relationships with
customers in the growing markets at the perimeter of its system, markets which
offer opportunities for growth in throughput due to their increasing demand
for energy. The Company has taken advantage of selected market expansion
opportunities, concentrating its efforts primarily in the Northeast and along
the East Coast. These markets are particularly attractive in that gas space
heating is not yet as widely used in these areas as in the Company's
traditional service areas of western Pennsylvania, eastern Ohio, West Virginia
and upstate New York. Because of its large gas storage capacity and the
location of its gridlike pipeline system in close proximity to these markets,
the Company has an opportunity to be an important gas supplier to utilities
with growing space-heating markets and for customers seeking an
environmentally clean, efficient fuel for electric generation.
 
   RETAIL UNBUNDLING
 
Similar to the unbundling of the services provided by gas pipeline companies,
gas distribution companies are now preparing for the expected deregulation and
unbundling of the retail energy market. To this end, on September 25, 1996,
East Ohio Gas filed a proposal with the Public Utilities Commission of Ohio to
permit open access for all of its Ohio customers. If approved, open access
service to customers who do not already have such an option--small business
and residential customers--would be phased in. Under open access programs,
natural gas suppliers other than the local gas utility can use the utility's
existing lines to deliver gas to customers. Under this proposal, Ohio
customers would also have the option of continuing to purchase natural gas
from East Ohio Gas. In addition, Peoples Natural Gas plans to open its system
to customer choice in Pennsylvania during the spring of 1997. Peoples Natural
Gas has begun a customer information campaign to educate customers about their
new options for unbundled service.
 
In addition to the initiatives at East Ohio Gas and Peoples Natural Gas, in
early 1997 the Company formed a new nonregulated unit, CNG Retail Services
Corporation. This subsidiary was created to market natural gas, electricity,
and related products and services to residential, commercial and small
industrial customers, including those within the Company's traditional service
territories. This new subsidiary is expected to enable the Company to take
full advantage of emerging deregulated energy markets for both gas and
electricity.
 
   INTERNATIONAL ACTIVITIES
 
In December 1996, CNG International and El Paso Energy Corporation (El Paso)
entered into a joint venture to own and operate the Australian pipeline assets
formerly held by Tenneco Energy. CNG International and El Paso each own 30
percent of Epic Energy, an Australian entity formed to hold the investment's
operating assets. The remaining 40 percent ownership interest in Epic Energy
is held equally among four Australian investors--Allgas Energy, AMP
Investments, Axion Funds Management and Hastings Funds Management. The primary
operating assets of the venture include two major long-distance natural gas
pipelines from Australia's Cooper Basin. One of the pipelines carries gas from
the city of Moomba south to Adelaide, while the other was recently built and
will carry gas from the city of Ballera east to Wallumbilla, Queensland. CNG
International's net investment in Epic Energy totaled $38.7 million at
December 31, 1996 and will be accounted for under the equity method.
 
A marketing alliance formed in late 1994 among CNG Energy Services and two
Canadian firms, Hydro-Quebec and Noverco, was terminated in December 1996. The
informal alliance created by the three companies did not evolve into a formal
partnership due principally to regulatory impediments.

ITEM 1.  BUSINESS (Continued)
 
   ADDITIONAL USES FOR NATURAL GAS
 
During 1996, the Company continued its involvement with a number of gas
burning technologies that provide opportunities to improve customer efficiency
while promoting the use of natural gas in markets that are not sensitive to
the weather or economic downturn. The advancement of such technologies appears
beneficial as business entities strive to comply with provisions of the Clean
Air Act, legislation which applies strict anti-pollution standards to
factories, fleet and mass transit vehicles, and electric power plants. The law
is likely to increase demand for natural gas, but the extent thereof will
depend on how the Act is implemented and enforced. Gas demand could also
increase as the result of the Energy Policy Act of 1992 which requires and
encourages large vehicle fleets to operate on alternative fuels such as
natural gas. The Energy Policy Act also created a new class of independent
power producers exempt from utility regulation, which could lead to the
construction of additional gas-fueled generating facilities.
 
The Company is also pursuing other technological opportunities, including gas
cooling equipment, fuel cell power generation, coal drying processes and the
promotion of natural gas powered vehicles (NGVs). Fleet operators and mass
transit authorities are using NGVs for both fuel cost efficiencies and to
reduce environmental pollution. Despite the environmental benefits of NGVs, it
appears unlikely that such vehicles will replace a significant number of
gasoline powered vehicles in the near future, given the lack of a nationwide
network of refueling facilities and the current cost of retrofitting vehicles.
However, effective September 1, 1996, the Energy Policy Act requires state
fleets and alternate fuel providers in the nation's 250 largest urban areas to
acquire alternative fuel vehicles. A certain percentage of new light-duty
fleet vehicles must be capable of operating on alternative fuels, which
include natural gas.
 
RATE MATTERS
 
The regulated subsidiaries continue to seek general rate increases on a timely
basis to recover increased operating costs and to ensure that rates of return
are compatible with the cost of raising capital. In addition to general rate
increases, subsidiary companies make separate filings with their respective
regulatory commissions to reflect changes in the costs of purchased gas.
 
As previously reported, on September 25, 1996, Virginia Natural Gas filed an
expedited rate application with the Virginia State Corporation Commission
requesting an annual revenue increase of $13.9 million. The requested rate
increase reflects the recovery of higher operating costs and additional
investment in facilities required to serve customers on Virginia Natural Gas'
system. The new rates went into effect, subject to refund, on October 25,
1996.

ITEM 2.  PROPERTIES (Concluded)

   GAS PURCHASE CONTRACT RESERVES (AT DECEMBER 31, 1996) AND AVAILABILITY OF
     SUPPLY (CALENDAR YEAR 1997)
 
Gas purchase reserves under contract with independent producers in the
Appalachian area total 381 Bcf at December 31, 1996. In addition, at December
31, 1996, the Company had gas supply contracts with various other producers
and marketers with contract lengths ranging from a few months to eight years.
The volume of gas available to the Company under these supply contracts totals
284 Bcf if all volumes are requested. These gas purchase contract reserve and
gas supply contract volume amounts are as contained in the February 11, 1997
report of Ralph E. Davis Associates, Inc. Of the total 381 Bcf under contract
from Appalachian producers, the volume of gas expected to be purchased in 1997
under such contracts is not estimable as such contracts are generally life-of-
the-well arrangements and contain provisions adaptable to changing market
conditions. Of the total 284 Bcf available under contract from other producers
and marketers, approximately 211 Bcf of gas will be available to the Company
in 1997, assuming all volumes are requested.
 
The Company anticipates that substantial volumes of gas will be available for
purchase during 1997 on the spot market. Due to the nature of spot market
transactions, the volumes of such gas available to the Company in 1997 cannot
be reasonably estimated. However, for the calendar year 1997, the Company
expects its distribution subsidiaries to have approximately 356 Bcf of firm
transport capacity available on upstream pipelines and 124 Bcf of storage
capacity available to meet their customer requirements.
 
The volumes expected to be available from Company-owned wells in 1997 amount
to 158 Bcf of gas and 7,731 thousand barrels of oil. Included in these amounts
are 155 Bcf of gas and 7,731 thousand barrels of oil expected to be available
from the Company's non-cost-of-service properties. The foregoing volumes are
based on the Company's current production estimates of proved gas and oil
reserves. Actual production may differ from these amounts due to a number of
factors, including changing market conditions and the acquisition or sale of
reserves.

     3.  The annual meetings of the stockholders for the election of directors
shall be held at the office of the corporation in the City of Wilmington, County
of New Castle, State of Delaware, or at such other place, within or without the

who may be present.

     10.  The holders of a majority of the stock issued and outstanding and
entitled to vote thereat, present in person or represented by proxy, shall be
requisite and shall constitute a quorum at all meetings of the stockholders for
the transaction of business except as otherwise provided by statute, by the
certificate of incorporation or by these Bylaws.  If, however, such quorum shall
not be present or represented at any meeting of the stockholders, the
stockholders entitled to vote thereat, present in person or represented by
proxy, shall have power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum shall be present or

<PAGE>
 
quorum shall be present or represented any business may be transacted which
might have been transacted at the meeting as originally notified.

     11.  When a quorum is present at any meeting, the vote of the holders of a
majority of the stock having voting power present in person or represented by
proxy shall decide any question brought before such meeting, unless the question

incorporation or of these Bylaws, a different vote is required in which case
such express provision shall govern and control the decision of such question.

     12.  At any meeting of the stockholders every stockholder having the right
to vote shall be entitled to vote in person, or by proxy appointed by an
instrument in writing subscribed by such stockholder and bearing a date not more

stockholders entitled to vote, no share of stock shall be voted on at any
election of directors which shall have been transferred on the books of the
corporation within twenty days next preceding such elections of directors.

     12-A.  The stockholders of the corporation may act by written consent in

                                   ---------

     13.  The number of directors which shall constitute the whole Board shall
be fixed by resolution of a majority of the whole Board.  The directors shall be
elected at annual meetings of stockholders and shall be divided into three
classes as nearly equal in number as possible.  The term of office of the first
class shall expire on the date of the 1985 annual meeting of stockholders; the
term of office of the second class shall expire one year thereafter; and that of
the third class, two years thereafter.  At each annual meeting after such
classification, the successors to the class of directors whose terms shall
expire in that year, shall be elected directors for a term of three years
except, however, the Board may, by resolution adopted by a majority of the whole
Board, elect directors to serve for interim periods.  Each director shall be
elected to serve until his successor shall be elected and shall qualify,
provided that the term of office of a director who is an employee of the Company
or any of its subsidiary companies shall


                                       3
<PAGE>
 
expire contemporaneously with his or her retirement from active service with the
Company, except in such case where the majority of the Board requests that an
employee director continue to serve, and provided further that the term of
office of a director shall expire on the date of the annual meeting immediately
subsequent to the date of his or her 70th birthday. Directors need not be
stockholders.

     13-A.  Unless recommended by the board of directors for election, no person
shall be elected a director, unless notice in writing of a nomination by a
stockholder of the corporation shall be received by the secretary of the
corporation not more than sixty and not less than thirty calendar days before
the date of the meeting at which the election is to take place.  Such notice
must set forth (i) the name, age, business address and (if known) residence
address of each nominee proposed in such notice; (ii) the principal occupation
or employment of each such nominee; (iii) a description of the business
experience during the last five years of each such nominee; and (iv) the number
of shares of capital stock of the corporation beneficially owned by each such
nominee.  In addition, such notice must be signed by a stockholder duly
qualified to attend and vote at the meeting (other than the person or persons
nominated) and must contain a notice in writing signed by each nominee of his
willingness to be elected and to serve as a director.

     If a nomination by a stockholder is not made in accordance with the
foregoing procedures, the chairman of the meeting shall have the power to
declare such nomination to be null, void and of no force or effect and to
disregard such nomination in conducting the election of directors at such
meeting.

     14.  The directors may hold their meetings and keep the books of the
corporation outside of Delaware, at such offices of the corporation or at such
other places as they may from time to time determine.

     15.  If the office of any director or directors becomes vacant by reason of
death, resignation, retirement, disqualification, removal from office, or
otherwise a majority of the remaining directors, though less than a quorum,
shall choose a successor or successors, who shall hold office for the unexpired
term in respect to which such vacancy occurred.

     16.  The property and business of the corporation shall be managed by its
board of directors which may exercise all such powers of the corporation and do
all such lawful acts and things as are not by statute or by the certificate of
incorporation or by these by laws directed or required to be exercised or done
by the stockholders.

     17.  The board of directors may, by resolution or resolutions passed by a
majority of the whole board, designate one or more committees, each committee to
consist of two or more of the directors of the corporation, which to the extent

     20-A.  Each person who at any time is, or shall have been a director,
officer, or employee of the Corporation, or serves or has served as a director,
officer, employee, fiduciary or other representative of another company,
partnership, joint venture, trust, association or other enterprise (including
any employee benefit plan), where such service was specifically requested by the
Corporation in accordance with clause (e) below, or the established guidelines
for participation in outside positions (such service hereinafter being referred
to as "Outside Service"), and is threatened to be or is made a party to any
threatened, pending, or completed claim, action, suit or Proceeding, whether
civil, criminal, administrative or investigative ("Proceeding"), by reason of
the fact that he is, or was, a director, officer or employee of the Corporation

other enterprise, shall be indemnified against expenses (including attorney's
fees), judgments, fines  


                                       5

and amounts paid in settlement ("Loss") actually and reasonably incurred by him
in connection with any such Proceeding to the full extent permitted under the
General Corporation Law of the State of Delaware, as the same exists or may
hereafter be amended, (but, in the case of any such amendment, only to the
extent that such amendment permits the Corporation to provide broader
indemnification rights than said Law permitted the Corporation to provide prior
to such amendment). The Corporation shall indemnify any person seeking indemnity
in connection with any Proceeding (or part thereof) initiated by such person
only if such Proceeding (or part thereof) initiated by such person was
authorized by the Board of Directors of the Corporation. With respect to any
Loss arising from Outside Service, the Corporation shall provide such
indemnification only if and to the extent that (i) such other company,
partnership, joint venture, trust, association or enterprise is not legally
permitted or financially able to provide such indemnification, and (ii) such
Loss is not paid pursuant to any insurance policy other than any insurance
policy maintained by the Corporation.

     20-B.  The right to be indemnified pursuant hereto shall include the right
to be paid by the Corporation for expenses, including attorney's fees, incurred
in defending any such Proceeding in advance of its final disposition; provided,
however, that the payment of such expenses in advance of the final disposition
of such Proceeding shall be made only upon delivery to the Corporation of an
undertaking, by or on behalf of such director, officer, or employee, in which
such director, officer or employee agrees to repay all amounts so advanced if it
should be determined ultimately that such director, officer or employee is not
entitled to be indemnified under applicable law.

     20-C.  The right of any director or officer (but not employee) to be
indemnified or to the reimbursement or advancement of expenses pursuant hereto
(i) is a contract right based upon good and valuable consideration, pursuant to
which the person entitled thereto may bring suit as if the provisions hereof
were set forth in a separate written contract between the Corporation and the
director or officer, and (ii) shall continue to exist after the rescission or
restrictive modification hereof with respect to events occurring prior thereto.

     20-D.  The right to be indemnified or to the reimbursement or advancement
of expenses pursuant hereto shall in no way be exclusive of any other rights of
indemnification or advancement to which any such director, officer or employee
may be entitled, under any bylaw, agreement, vote of stockholders or
disinterested directors or otherwise both as to action in his official capacity
and as to action in another capacity while holding such office, and shall



                                       6

continue as to a person who has ceased to be a director, officer or employee and
shall inure to the benefit of the heirs, executors and administrators of such
person.

employee or fiduciary of (i) another corporation of which a majority of the
shares entitled to vote in the election of its directors is held by the
Corporation at the time of such service, or (ii) any employee benefit plan of
the Corporation or of any corporation referred to in clause E(i), shall be
deemed to be doing or have done so at the request of the Corporation.

substantial responsibility, to reward such employees for superior performance

Company's shareholders.  The Plan is designed to meet this intent by providing
such employees with a proprietary interest in pursuing the long-term growth,

additional motivation to continue in the Company's employ and to further its

          or agreement relating to, or Award made under, the Plan;

                  (vii)  to prescribe the form of each Award Agreement, which

                  (viii)  to adopt, amend, suspend, waive and rescind such rules

          SECTION 4.  Shares Subject to the Plan.
                      ---------------------------

which Awards may be granted under the Plan, subject to adjustment as provided in
Section 8.01 of the Plan, shall be 4,000,000.


          For purposes of this Section 4.01, the number of Shares to which an
Award relates shall be counted against the number of Shares reserved and
available under the Plan at the time of grant of the Award, unless such number
of Shares cannot be determined at that time, in which case the number of Shares
actually distributed pursuant to the Award shall be counted against the number
of Shares reserved and available under the Plan at the time of distribution;
provided, however, that Awards related to or retroactively added to, or granted
in tandem with, substituted for or converted into, other Awards shall be counted
or not counted against the number of Shares reserved and available under the
Plan in accordance with procedures adopted by the Committee so as to ensure
appropriate counting but avoid double counting; and, provided further, that the
number of Shares deemed to be issued under the Plan upon exercise of an Option
or another stock-based award in the nature of a stock purchase right shall be
reduced by the number of Shares surrendered by the Participant in payment of the
exercise or purchase price of the Award.

          If any Shares to which an Award relates are forfeited, or payment is
made to the Participant in the form of cash, cash equivalents or other property
other than Shares, or the Award otherwise terminates without payment being made
to the Participant in the form of Shares, any Shares counted against the number
of Shares reserved and available under the Plan with respect to such Award
shall, to the extent of any such forfeiture, alternative payment or termination,
again be available for Awards under the Plan.

          5.01  Awards may be granted only to individuals who are employees of
the Company or any Affiliate and who are not directors or officers of the
Company for purposes of Section 16 of the Exchange Act.  In determining the
eligibility of an employee to receive an Award, the Committee shall consider the
position and responsibilities of the employee being considered, the nature and
value to the Company or a Subsidiary of his services and accomplishments, his
present and potential contribution to the success of the Company and its
Subsidiaries and such other factors as the Committee may deem relevant.

          Option and in no event shall be less than the par value of a Share.

          Committee upon termination of employment (as determined under criteria

                -------------------                                         
exchange or buy out any previously granted Award for a payment in cash, Shares,
another Award or other property, based on such terms and conditions as the
Committee shall determine and communicate to the Participant at the time that
such offer is made.

          SECTION 7.  General Terms of Awards.
                      ----------------------- 

          7.01  Stand-Alone, Tandem and Substitute Awards.  Awards granted under
                -----------------------------------------

addition to, in tandem with or in substitution for, any other Award granted
under the Plan, or any other plan of the Company or any Affiliate (subject to
the terms of Section 10.01) including a business entity to be acquired by the
Company.  If an Award is granted in substitution for another Award or award, the
Committee shall require the surrender of such other Award or award in
consideration for the grant of the new Award.  Awards granted in addition to or
in tandem with other Awards or awards may be granted either at the same time as
or at a different time from the grant of such other Awards or awards.  The
exercise price of any Option, the grant price of any Stock Appreciation Right or
the purchase price of any other Award conferring a right to purchase Shares:

                  (i) granted in substitution for an outstanding Award or award
          shall either be not less than the Fair Market Value of Shares at the
          date such substitute Award is granted or not less than such Fair
          Market Value at that date reduced to reflect the Fair Market Value of
          the Award or award required to be surrendered by the Participant as a
          condition to receipt of a substitute Award; or

                  (ii) retroactively granted in tandem with an outstanding Award
          or award shall be either not less than the Fair Market Value of Shares
          at the date of grant of the later Award or equal to the Fair Market

                                      -11-
<PAGE>
 
          Value of Shares at the date of grant of the earlier Award or award.

                    7.02  Term of Awards.  The term of each Award shall be for
                          --------------                                      
such period as may be determined by the Committee.
 
          7.03  Form of Payment of Awards.  Subject to the terms of the Plan and
                -------------------------                                       
any applicable Award Agreement, payments or substitutions to be made by the
Company or an Affiliate upon the grant or exercise of an Award may be made in
such forms as the Committee shall determine at the time of grant or thereafter
(subject to the terms of Section 10.01), including, without limitation, cash,
Shares, other Awards or other property or any combination thereof, and may be
made in a single payment or substitution, in installments or on a deferred
basis, in each case in accordance with rules and procedures established by the
Committee.  Such rules and procedures may include, without limitation,
provisions for the payment or crediting of reasonable interest on installment or
deferred payments or the grant or crediting of Dividend Equivalents in respect
of installment or deferred payments.

          7.04  Limits on Transfer of Awards; Beneficiaries.  No right or
                -------------------------------------------              
interest of a Participant in any Award shall be  pledged, encumbered or
hypothecated to or in favor of any Person other than the Company or an
Affiliate, or shall be subject to any lien, obligation or liability of such
Participant to any Person other than the Company or an Affiliate.  Unless
otherwise determined by the Committee, no Award and no rights or interests
therein shall be assignable or transferable by a Participant otherwise than by
will or the laws of descent and distribution except to the Company or any
Affiliate under the terms of the Plan; provided, however, that, if so determined
by the Committee, a Participant may, in the manner established by the Committee,
designate a beneficiary or beneficiaries to exercise the rights of the
Participant, and to receive any distribution with respect to any Award, upon the
death of the Participant.  A beneficiary, guardian, legal representative or
other Person claiming any rights under the Plan from or through any Participant
shall be subject to all the terms and conditions of the Plan and any Award
Agreement applicable to such Participant as well as any additional restrictions
or limitations deemed necessary or appropriate by the Committee.

          7.05  Registration and Listing Compliance.  No Award shall be paid and
                -----------------------------------                             
no Shares shall be distributed with respect to any Award in a transaction
subject to the registration requirements of the Securities Act of 1933, as
amended, or any state securities law or subject to a listing requirement under
any listing agreement between the Company and any national securities exchange,
and no Award shall confer upon any Participant rights to such delivery or
distribution, until such laws and contractual obligations of the Company have
been complied with in all material respects.

          7.06  Stock Certificates.  All certificates for Shares delivered under
                ------------------                                              
the terms of the Plan shall be subject to such stop-transfer orders and other
restrictions as the Committee may deem advisable under federal or state
securities laws, rules and regulations thereunder, and the rules of any national
securities exchange or automated quotation system on which Shares are listed or
quoted.  The Committee may cause a legend or legends to be placed on any such
certificates to make appropriate reference to such restrictions or any other
restrictions or limitations that may be applicable to Shares.  In addition,
during any period in which Awards or Shares are subject to restrictions or
limitations under the terms of the Plan or any Award Agreement, or during any
period during which delivery or receipt of an Award or Shares has been deferred
by the Committee or a Participant, the Committee may require any Participant to
enter into an agreement providing that certificates representing Shares issuable
or issued pursuant to an Award shall remain in the physical custody of the
Company or such other Person as the Committee may designate.

          SECTION 8.  Adjustment Provisions.
                      --------------------- 

          8.01  In the event that the Committee shall determine that any
dividend or other distribution (whether in the form of cash, Shares, other
securities or other property), recapitalization, stock split, reverse stock
split, reorganization, merger, consolidation, split-up, spin-off, combination,
repurchase, exchange of Shares or other securities of the Company, or other
similar corporate transaction or event affects the Shares such that an
adjustment is determined by the Committee to be appropriate in order to prevent
dilution or enlargement of Participants' rights under the Plan, then the
Committee shall, in such manner as it may deem equitable, adjust any or all of
(i) the number and kind of Shares which may thereafter be issued in connection
with Awards; (ii) the number 


                                      -13-
<PAGE>
 
and kind of Shares issued or issuable in respect of outstanding Awards; and
(iii) the exercise price, grant price or purchase price relating to any Award
or, if deemed appropriate, make provision for a cash payment with respect to any
outstanding Award. In addition, the Committee is authorized to make adjustments
in the terms and conditions of, and the criteria in, Awards in recognition of
unusual or nonrecurring events (including, without limitation, events described
in the preceding sentence) affecting the Company or any Affiliate or the
financial statements of the Company or any Affiliate, or in response to changes
in applicable laws, regulations or accounting principles.

          SECTION 9.  Change of Control Provisions.
                      ---------------------------- 

          9.01  Acceleration of Exercisability and Lapse of Restrictions; Cash-
                --------------------------------------------------------------
Out of Awards.  In the event of a Change of Control, the following acceleration
- -------------
and cash-out provisions shall apply unless otherwise provided by the Committee
at the time of the Award grant.

                  (i) All outstanding Awards pursuant to which the Participant
          may have rights the exercise of which is restricted or limited shall
          become fully exercisable; unless the right to lapse of restrictions or
          limitations is waived or deferred by a Participant prior to such
          lapse, all restrictions or limitations (including risks of forfeiture
          and deferrals) on outstanding Awards subject to restrictions or
          limitations under the Plan shall lapse; and all performance criteria
          and other conditions to payment of Awards under which payments of
          cash, Shares or other property are subject to conditions shall be
          deemed to be achieved or fulfilled and shall be waived by the Company.

                  (ii) For a period of up to 60 days following a Change of
          Control, the Participant may elect to surrender any outstanding Award
          and to receive, in full satisfaction therefor, a cash payment equal to
          the value of such Award calculated on the basis of the Change of
          Control Price of any Shares or the Fair Market Value of any property
          other than Shares relating to such Award; provided, however, that in
                                                    -----------------         
          the case of a Change of Control described in Section 9.03.l(ii), (iii)
          or (iv) hereof, the payment described in this


                                       -14-
<PAGE>
 
          sentence shall be made in the same form (i.e., cash, shares, other
          securities or a combination thereof) as holders of Shares receive in
          exchange for their Shares in the transaction that results in the
          Change of Control. In the event that an Award is granted in tandem
          with another Award such that the Participant's right to payment for
          such Award is an alternative to payment of another Award, the
          Participant electing to surrender any such tandem Award shall
          surrender all alternative Awards related thereto and receive payment
          for the Award which produces the highest payment to the Participant.

          9.02  Creation and Funding of Trust.  Upon the earlier of the
                -----------------------------                          
occurrence of a Potential Change of Control or a Change of Control, the Company
shall deposit with the trustee of a trust for the benefit of Participants monies
or other property having a Fair Market Value at least equal to the value of
cash, Shares and other property to be paid or distributed in connection with
Awards outstanding at that date. The trust shall be a grantor trust which shall
preserve the "unfunded" status of Awards under the Plan. Subsequent to a
Potential Change of Control which is no longer continuing and prior to any
Change of Control, upon the request of the Company, the trustee shall deliver
the monies or other property held in the trust to the Company.

          9.03  Definition of Certain Terms.  For purposes of this Section 9,

          then-outstanding Voting Securities, except that there shall be
          excluded from the number of Voting Securities deemed to be
          beneficially owned by a Person a number of Voting Securities
          representing not more than 10 percent of the then-outstanding voting
          power if such Person is (a) eligible to file a Schedule 13G pursuant
          to Rule 13d-1(b)(1) under the Exchange Act with respect to

          or

                  (iv) the stockholders of the Company approve a plan of

          amount of any portion of the consideration consisting of cash or cash
          equivalents and (ii) the fair market value of any portion of the
          consideration consisting of real or personal property other than cash
          or cash equivalents, as established by an independent appraiser

          Control; or (ii) any Person (including the Company) publicly announces

Participants to satisfy obligations for the payment of withholding taxes and tax
liabilities in excess thereof.  This authority shall include authority to
withhold or receive Shares, Awards or other property and to make cash payments
in respect thereof in satisfaction of such tax obligations.

          11.03  No Right to Employment.  Nothing contained in the Plan or any
                 ----------------------                                       
Award Agreement shall confer, and no grant of an Award shall be construed as
conferring, upon any Participant any right to continue in the employ of the
Company or any Affiliate or to interfere in any way with the right of the
Company or any Affiliate to terminate his employment at any time or increase or
decrease his compensation from the rate in existence at the time of granting of
an Award, except as may be expressly provided in any Award Agreement or other
compensation arrangement.

          11.04  Unfunded Status of Awards; Creation of Trusts.  The Plan is
                 ---------------------------------------------              
intended to constitute an "unfunded" plan for incentive and deferred
compensation.  With respect to any payments not yet made to a Participant
pursuant to an Award, nothing contained in the Plan or any Award shall give any
such Participant any rights that are greater than those of a general unsecured
creditor of the Company; provided, however, that, in addition to the
requirements of Section 9.02, the Committee may authorize the creation of trusts
or make other arrangements to meet the Company's obligations under the Plan to
deliver cash, Shares or other property pursuant to any Award, which trusts or



                                      -19-

other arrangements shall be consistent with the "unfunded" status of the Plan
unless the Committee otherwise determines.

          11.05  No Limit on Other Compensatory Arrangements.  Nothing contained
                 -------------------------------------------                    
in the Plan shall prevent the Company or any Affiliate from adopting other or
additional compensation arrangements (which may include, without limitation,
employment agreements with executives and arrangements which relate to Awards
under the Plan), and such arrangements may be either generally applicable or
applicable only in specific cases.  Notwithstanding anything in the Plan to the
contrary, the terms  of each Award shall be construed so as to be consistent
with such other arrangements in effect at the time of the Award.

          11.06  No Fractional Shares.  No fractional Shares shall be issued or
                 --------------------                                          
delivered pursuant to the Plan or any Award.  The Committee shall determine
whether cash, other Awards or other property shall be issued or paid in lieu of
fractional Shares or whether such fractional Shares or any rights thereto shall
be forfeited or otherwise eliminated.

          11.07  Governing Law.  The validity, interpretation, construction and
                 -------------                                                 
effect of the Plan and any rules and regulations relating to the Plan shall be
governed by the laws of the State of Delaware (without regard to provisions
governing conflict of laws) and applicable federal law.

          11.08  Severability.  If any provision of the Plan or any Award is or
                 ------------                                                  
becomes or is deemed invalid, illegal or unenforceable in any jurisdiction, or
would disqualify the Plan or any Award under any law deemed applicable by the
Committee, such provision shall be construed or deemed amended to conform to
applicable laws or if it cannot be construed or deemed amended without, in the
determination of the Committee, materially altering the intent of the Plan, it
shall be deleted and the remainder of the Plan shall remain in full force and
effect; provided, however, that, unless otherwise determined by the Committee,
the provision shall not be construed or deemed amended or deleted with respect
to any Participant whose rights and obligations under the Plan are not subject
to the law of such jurisdiction or the law deemed applicable by the Committee.

           (vi)  to interpret and administer the Plan and any instrument or
     agreement relating to, or Award made under, the Plan;

          (vii)  to prescribe the form of each Award Agreement, which need not

         (viii)  to adopt, amend, suspend, waive and rescind such rules and

           (ix)  to correct any defect or supply any omission or reconcile any

            (x)  to make all other decisions and determinations as may be

     Any action of the Committee with respect to the Plan shall be final,
conclusive and binding on all Persons, including the Company, Affiliates,
Participants, any Person claiming any rights under the Plan from or through any
Participant, employees and stockholders.  The express grant of any specific

be construed as limiting any power or authority of the Committee.  The Committee
may delegate to officers or managers of the Company or of any Affiliate the

are not subject to Section 16 of the Exchange Act, to take such actions and
perform such functions under the Plan as the Committee may specify.  Each member

<PAGE>
 
Section 7.02.3, any and all powers, authorizations and discretions granted by
the Plan to the Committee shall likewise be exercisable at any time by the
Board.

     SECTION 4.  Shares Subject to the Plan.

     4.01  The maximum number of shares of Common Stock in respect for which
Awards may be granted under the Plan, subject to adjustment as provided in
Section 8.01 of the Plan, in each calendar year during any part of which the
Plan is effective shall be one percent (1%) of the total issued and outstanding
shares of the Common Stock as of the first day of each such year the Plan is in
effect, plus any shares which are reserved but not then subject to grants under
the Company's Long-Term Incentive Plan (the "LTIP") as of the date this Plan is
approved by the shareholders of the Company.  Notwithstanding the foregoing, in
no event shall more than three million (3,000,000) shares of Common Stock be
cumulatively available for Awards of Incentive Stock Options under the Plan.

     For purposes of this Section 4.01, the number of Shares to which an Award
relates shall be counted against the number of Shares reserved and available
under the Plan at the time of grant of the Award, unless such number of Shares
cannot be determined at that time, in which case the number of Shares actually
distributed pursuant to the Award shall be counted against the number of Shares
reserved and available under the Plan at the time of distribution; provided,
however, that Awards related to or retroactively added to, or granted in tandem
with, substituted for or converted into, other Awards shall be counted or not
counted against the number of Shares reserved and available under the Plan in
accordance with procedures adopted by the Committee so as to ensure appropriate
counting but avoid double counting.  Any unused portion of the number of shares
available for grant hereunder for any calendar year, together with any
additional shares that have become available under the LTIP, shall be carried
forward and be made available for Awards in succeeding calendar years.

     If any Shares to which an Award relates are forfeited, or payment is made
to the Participant in the form of cash, cash equivalents or other property other
than Shares, or the Award otherwise terminates without payment being made to the
Participant in the form of Shares, any Shares counted against the number of
Shares reserved and available under the Plan with respect to such Award shall,
to the extent of any such forfeiture, alternative payment or termination, again
be available for Awards under the Plan.

     Any Shares distributed pursuant to an Award may consist, in whole or in
part, of authorized and unissued Shares or of treasury Shares, including Shares
repurchased by the Company for purposes of the Plan.

     SECTION 5.  Eligibility.

     5.01  Awards may be granted only to individuals who are key employees
(including employees who also are directors or officers) of the Company or any
Affiliate; provided, however, that no Award shall be granted to any member of
the Committee or to any individual who has served as a member of the Committee
at any time during the one-year period prior to the date an Award is to be
granted to such individual.  In determining the eligibility of an employee to

                                      A-5
<PAGE>
 
receive an Award, the Committee shall consider the position and responsibilities
of the employee being considered, the nature and value to the Company or a
Subsidiary of his services and accomplishments, his present and potential
contribution to the success of the Company or its Subsidiaries and such other
factors as the Committee may deem relevant.

     SECTION 6.  Specific Terms of Awards.

     6.01  General.  Subject to the terms of the Plan and any applicable Award
Agreement, awards may be issued as set forth in this Section 6.  In addition,
the Committee may impose on any Award or the exercise thereof, at the date of
grant or thereafter (subject to the terms of Section 10.01), such additional
terms and conditions, not inconsistent with the provisions of the Plan, as the
Committee shall determine, including terms requiring forfeiture of Awards in the
event of termination of employment by the Participant.  Except as provided in
Section 7.01, or as required by applicable law, Awards shall be granted for no
consideration other than prior and future services.

     6.02  Options.  The Committee is authorized to grant Options to
Participants on the following terms and conditions:

            (i)  Exercise Price.  The exercise price per Share of an Option
     shall be determined by the Committee; provided, however, that, except as
     provided in Section 7.01, such exercise price shall not be less than the
     Fair Market Value of a Share on the date of grant of such Option and in no
     event shall be less than the par value of a Share.

           (ii)  Option Term.  The term of each Option shall be determined by
     the Committee.

          (iii)  Methods of Exercise.  The Committee shall determine the time or
     times at which an Option may be exercised in whole or in part, the methods
     by which such exercise price may be paid or deemed to be paid, and the form
     of such payment, including, without limitation, cash, Shares, other
     outstanding Awards or other property (including notes or other contractual
     obligations of Participants to make payment on a deferred basis, to the
     extent permitted by law) or any combination thereof, having a fair market
     value equal to the exercise price.

           (iv)  Incentive Stock Options.  The terms of any Incentive Stock
     Option granted under the Plan shall comply in all material respects with
     the provisions of Section 422A of the Code or any successor provision
     thereto.

     right other than one related to any Incentive Stock Option, at any time
     during a specified period before or after the date of 


                                      A-6
<PAGE>
 
     exercise, over (ii) the grant price of the Stock Appreciation Right as
     determined by the Committee as of the date of grant of the Stock
     Appreciation Right, which, except as provided in Section 7.01, shall not be
     less than the Fair Market Value of a Share on the date of grant.

           (ii)  Other Terms.  The term, methods of exercise, methods of
     settlement and any other terms and conditions of any Stock Appreciation
     Right shall be determined by the Committee.

Stock to Participants on the following terms and conditions:

            (i)  Issuance and Restrictions.  Restricted Stock shall be subject
     to such restrictions on transferability and other restrictions as the
     Committee may impose (including, without limitation, limitations on the
     right to vote Restricted Stock or the right to receive dividends thereon),
     which restrictions may lapse separately or in combination at such times,
     under such circumstances, in such installments or otherwise, as the
     Committee shall determine at the time of grant or thereafter.

           (ii)  Forfeiture.  Except as otherwise determined by the Committee at
     the time of grant or thereafter, upon termination of employment (as
     determined under criteria established by the Committee) during the
     applicable restriction period, Restricted Stock that is at that time
     subject to restrictions shall be forfeited and reacquired by the Company;
     provided, however, that the Committee may provide, by rule or regulation or
     in any Award Agreement, that restrictions on Restricted Stock shall be
     waived in whole or in part in the event of terminations resulting from
     specified causes, and the Committee may in other cases waive in whole or in
     part restrictions on Restricted Stock.

          (iii)  Certificates for Shares.  Restricted Stock granted under the
     Plan may be evidenced in such manner as the Committee shall determine,
     including, without limitation, issuance of certificates representing
     Shares.  Certificates representing Shares of Restricted Stock shall be
     registered in the name of the Participant and shall bear an appropriate
     legend referring to the terms, conditions and restrictions applicable to
     such Restricted Stock.

     6.05  Deferred Stock.  The Committee is authorized to grant Deferred Stock
to Participants on the following terms and conditions:

     expiration of the deferral period specified for the Award of Deferred Stock

     lapse at the expiration of the deferral period or at other specified times,
     separately or in combination, in installments or otherwise, as the
     Committee shall determine at the time of grant or thereafter.  A
     Participant awarded Deferred Stock shall have no voting rights and shall
     have no rights to receive dividends in respect of Deferred Stock, unless
     and only to the extent that the Committee shall award Dividend Equivalents
     in respect of such Deferred Stock.

     is at that time subject to deferral (other than a deferral at the election
     of the Participant) shall be forfeited; provided, however, that the
     Committee may provide, by rule or regulation or in any Award Agreement,
     that forfeiture of Deferred Stock shall be waived in whole or in part in
     the event of terminations resulting from specified causes, and the

     granted, in whole or in part, as the Committee shall establish.  The
     performance criteria and all other terms and conditions of the Performance
     Award shall be determined by the Committee upon the grant of each
     Performance Award or thereafter.

           (ii)  Other Terms.  A Performance Award may be denominated or payable
     in cash, deferred cash, Shares, other Awards or other property, and other
     terms and conditions of Performance Awards shall be, as determined by the
     Committee.

     6.07  Dividend Equivalents.  The Committee is authorized to grant Dividend
Equivalents to Participants.  Dividend Equivalents shall confer upon the
Participant rights to receive, currently or on a deferred basis, interest or
dividends, or interest or dividend equivalents, with respect to a number of
Shares, or otherwise, as determined by the Committee.  The Committee may provide
that Dividend Equivalents shall be paid or distributed when accrued or shall be
deemed to have been reinvested in additional Shares or additional Awards or
otherwise reinvested.

     6.08  Other Stock-Based Awards.  The Committee is authorized, subject to
limitations under applicable law, to grant to Participants such other Awards
that are denominated or payable in, valued in whole or in part by reference to,
or otherwise based on, or related to, Shares, as deemed by the Committee to be
consistent with the purposes of the Plan and, with respect to Participants who
are subject to Section 16 of the Exchange Act, to comply with Rule 16b-3 and
applicable law including, without limitation, purchase rights, Shares awarded
which are not subject to any restrictions or conditions, convertible or
exchangeable debentures, exchangeable securities or other rights convertible or
exchangeable into Shares, as the Committee in its discretion may determine.  The
Committee shall determine the terms and conditions of such Awards.  Except as
provided in Section 7.01, Shares or securities delivered pursuant to a purchase
right granted under this Section 6.08 shall be purchased for such consideration,
paid for by such methods and in such forms, including, without limitation, cash,
Shares, outstanding Awards or other property or any combination thereof, as the
Committee shall determine, provided that the value of which consideration shall
not be less

                                      A-8
<PAGE>
 
than the Fair Market Value of such Shares on the date of grant of such purchase
right and in no event shall be less than the par value of a Share.

     6.09  Exchange Provisions.  The Committee may at any time offer to exchange
or buy out any previously granted Award for a payment in cash, Shares, another
Award or other property, based on such terms and conditions as the Committee
shall determine and communicate to the Participant at the time that such offer
is made.

     SECTION 7.  General Terms of Awards.

     7.01  Stand-Alone, Tandem and Substitute Awards.  Awards granted under the
Plan may, in the discretion of the Committee, be granted either alone or in
addition to, in tandem with or in substitution for, any other Award granted
under the Plan or any award granted under the Long-Term Incentive Plan, or any
other plan of the Company or any Affiliate (subject to the terms of Section
10.01) including a business entity to be acquired by the Company.  If an Award
is granted in substitution for another Award or award, the Committee shall
require the surrender of such other Award or award in consideration for the
grant of the new Award.  Awards granted in addition to or in tandem with other
Awards or awards may be granted either at the same time as or at a different
time from the grant of such other Awards or awards.  The exercise price of any
Option, the grant price of any Stock Appreciation Right or the purchase price of
any other Award conferring a right to purchase Shares:

            (i)  granted in substitution for an outstanding Award or award shall
     either be not less than the Fair Market Value of Shares at the date such
     substitute Award is granted or not less than such Fair Market Value at that
     date reduced to reflect the Fair Market Value of the Award or award
     required to be surrendered by the Participant as a condition to receipt of
     a substitute Award; or

           (ii)  retroactively granted in tandem with an outstanding Award or
     award shall be either not less than the Fair Market Value of Shares at the
     date of grant of the later Award or equal to the Fair Market Value of
     Shares at the date of grant of the earlier Award or award.

     7.02  Certain Restrictions Under Rule 16b-3.  If, at any time, the
provisions of this Plan are inconsistent with Rule 16b-3 as then in effect, this
Plan shall be deemed to be amended, without further action on the part of the
Committee or the Board, to the extent necessary to comply with Rule 16b-3, as
then in effect, except to the extent any such amendment to the Plan requires
stockholder approval.

           7.02.1  Six-Month Limitations on Sales and Exercises.  Other
     provisions of the Plan and any Award Agreement notwithstanding, equity
     security, as defined under the Exchange Act, offered pursuant to the Plan
     to a Participant who is at the time subject to Section 16 of the Exchange
     Act may not be sold for at least six months after acquisition, except in
     case of death or Disability, and any derivative security, as defined under
     the Exchange Act, issued pursuant to the Plan to a Participant who is at
     the time subject to Section 16 of the Exchange Act

                                      A-9
<PAGE>
 
     shall not be exercisable for at least six months, except in case of death
     or Disability, unless such sale or exercise is permissible under the
     provisions of Rule 16b-3.

          7.02.2  Nontransferability.  Other provisions of the Plan and any
     Award Agreement notwithstanding, Awards which constitute derivative
     securities, including Options, Stock Appreciation Rights and other rights,
     shall not be transferable by a Participant except by will or the laws of
     descent and distribution and shall be exercisable during a Participant's
     lifetime only by such Participant or his guardian or legal representative;
     provided, however, that the Committee may determine that these restrictions
     on transferability shall not apply to Awards granted to any Participant
     who, at the time of the initial grant and the transfer, is not subject to
     Section 16 of the Exchange Act.

          7.02.3  Decisions Required to be Made by the Committee.  Other
     provisions of the Plan and any Award Agreement notwithstanding, if any
     decision regarding an Award or the exercise of any right by a Participant,
     at any time such Participant is subject to Section 16 of the Exchange Act,
     is required to be made or approved by the Committee in order that the Plan
     will continue to meet the requirements of Rule 16b-3 or in order that a
     transaction by such Participant will be exempt under Rule 16b-3, then the
     Committee shall retain full and exclusive power and authority to make such
     decision or to approve or disapprove any such decision by the Participant.

     7.03  Term of Awards.  The term of each Award shall be for such period as
may be determined by the Committee; provided, however, that in no event shall
the term of any Incentive Stock Option, or a Stock Appreciation Right granted in
tandem therewith, exceed a period of ten years from the date of its grant.

     7.04  Form of Payment of Awards.  Subject to the terms of the Plan and any
applicable Award Agreement, payments or substitutions to be made by the Company
or an Affiliate upon the grant or exercise of an Award may be made in such forms
as the Committee shall determine at the time of grant or thereafter (subject to
the terms of Section 10.01), including, without limitation, cash, Shares, other
Awards or other property or any combination thereof, and may be made in a single
payment or substitution, in installments or on a deferred basis, in each case in
accordance with rules and procedures established by the Committee.  Such rules
and procedures may include, without limitation, provisions for the payment or
crediting of reasonable interest on installment or deferred payments or the
grant or crediting of Dividend Equivalents in respect of installment or deferred
payments.

     7.05  Limits on Transfer of Awards; Beneficiaries.  No right or interest of
a Participant in any Award shall be pledged, encumbered or hypothecated to or in
favor of any Person other than the Company or an Affiliate, or shall be subject
to any lien, obligation or liability of such Participant to any Person other
than the Company or an Affiliate.  Unless otherwise determined by the Committee
(subject to the requirements of Section 7.02.2 hereof), no Award and no rights
or interests therein shall be assignable or transferable by a Participant
otherwise than by will or the laws of descent and distribution except to the
Company or any Affiliate under the terms of the Plan; provided,

                                      A-10
<PAGE>
 
however, that, if so determined by the Committee, a Participant may, in the
manner established by the Committee, designate a beneficiary or beneficiaries to
exercise the rights of the Participant, and to receive any distribution with
respect to any Award, upon the death of the Participant. A beneficiary,
guardian, legal representative or other Person claiming any rights under the
Plan from or through any Participant shall be subject to all the terms and
conditions of the Plan and any Award Agreement applicable to such Participant as
well as any additional restrictions or limitations deemed necessary or
appropriate by the Committee.

     7.06  Registration and Listing Compliance.  No Award shall be paid and no
Shares shall be distributed with respect to any Award in a transaction subject
to the registration requirements of the Securities Act of 1933, as amended, or
any state securities law or subject to a listing requirement under any listing
agreement between the Company and any national securities exchange, and no Award
shall confer upon any Participant rights to such delivery or distribution, until
such laws and contractual obligations of the Company have been complied with in
all material respects.

     7.07  Stock Certificates.  All certificates for Shares delivered under the
terms of the Plan shall be subject to such stop-transfer orders and other
restrictions as the Committee may deem advisable under federal or state
securities laws, rules and regulations thereunder, and the rules of any national
securities exchange or automated quotation system on which Shares are listed or
quoted.  The Committee may cause a legend or legends to be placed on any such
certificates to make appropriate reference to such restrictions or any other
restrictions or limitations that may be applicable to Shares.  In addition,
during any period in which Awards or Shares are subject to restrictions or
limitations under the terms of the Plan or any Award Agreement, or during any
period during which delivery or receipt of an Award or Shares has been deferred
by the Committee or a Participant, the Committee may require any Participant to
enter into an agreement providing that certificates representing Shares issuable
or issued pursuant to an Award shall remain in the physical custody of the
Company or such other Person as the Committee may designate.

     SECTION 8.  Adjustment Provisions.

     8.01  In the event that the Committee shall determine that any dividend or
other distribution (whether in the form of cash, Shares, other securities or
other property), recapitalization, stock split, reverse stock split,
reorganization, merger, consolidation, split-up, spin-off, combination,
repurchase, exchange of Shares or other securities of the Company, or other
similar corporate transaction or event affects the Shares such that an
adjustment is determined by the Committee to be appropriate in order to prevent
dilution or enlargement of Participants' rights under the Plan, then the
Committee shall, in such manner as it may deem equitable, adjust any or all of
(i) the number and kind of Shares which may thereafter be issued in connection
with Awards; (ii) the number and kind of Shares issued or issuable in respect of
outstanding Awards; and (iii) the exercise price, grant price or purchase price
relating to any Award or, if deemed appropriate, make provision for a cash
payment with respect to any outstanding Award; provided, however, in each case,
that, with respect to Incentive Stock Options, no such adjustment shall be
authorized to the extent that such authority would cause

                                      A-11
<PAGE>
 
the plan to violate Section 422A(b)(1) of the Code or any successor provision
thereto. In addition, the Committee is authorized to make adjustments in the
terms and conditions of, and the criteria in, Awards in recognition of unusual
or nonrecurring events (including, without limitation, events described in the
preceding sentence) affecting the Company or any Affiliate or the financial
statements of the Company or any Affiliate, or in response to changes in
applicable laws, regulations or accounting principles.

     SECTION 9.  Change of Control Provisions.

     9.01  Acceleration of Exercisability and Lapse of Restrictions; Cash-Out of
Awards.  In the event of a Change of Control, the following acceleration and
cash-out provisions shall apply unless otherwise provided by the Committee at
the time of the Award grant.

            (i) All outstanding Awards pursuant to which the Participant may
     have rights the exercise of which is restricted or limited, shall become
     fully exercisable, except as may be otherwise provided in Section 7.02.1;
     unless the right to lapse of restrictions or limitations is waived or
     deferred by a Participant prior to such lapse, all restrictions or
     limitations (including risks of forfeiture and deferrals) on outstanding
     Awards subject to restrictions or limitations under the Plan shall lapse,
     except as may be otherwise provided in Section 7.02.1; and all performance
     criteria and other conditions to payment of Awards under which payments of
     cash, Shares or other property are subject to conditions shall be deemed to
     be achieved or fulfilled and shall be waived by the Company, except as may
     be otherwise required to comply with Rule 16b-3.

           (ii)  For a period of up to 60 days following a Change of Control,
     the Participant may elect to surrender any outstanding Award and to
     receive, in full satisfaction therefor, a cash payment equal to the value
     of such Award calculated on the basis of the Change of Control Price of any
     Shares or the Fair Market Value of any property other than Shares relating
     to such Award; provided, however, that in the case of an Incentive Stock
                    -----------------                                        
     Option, or a Stock Appreciation Right granted in tandem therewith, the
     payment shall be based upon the Fair Market Value of Shares on the date on
     which the Change of Control occurred; provided further, however, that in
                                           -------------------------         
     the case of a Change of Control described in Section 9.03.1(ii), (iii) or
     (iv) hereof, the payment described in this sentence shall be made in the
     same form (i.e., cash, shares, other securities or a combination thereof)
     as holders of Shares receive in exchange for their Shares in the
     transaction that results in the Change of Control.  Except as provided in
     Section 9.01(iii), in no event will an Award be surrendered or a
     Participant have the right to receive cash under this Section 9.01(ii) with
     respect to an Award (a) if the Participant is subject to Section 16 of the
     Exchange Act and at least six months shall not have elapsed from the date
     on which the Participant was granted the Award before the date of the
     Change of Control (unless this restriction is not at such time required
     under Rule 16b-3) or (b) if the Participant had the power to control the
     occurrence or timing of the Change of Control.

                                      A-12
<PAGE>
 
          (iii)  In the event that any Award is subject to limitations under
     Section 7.02.1 or Section 9.01(ii) at the time of a Change of Control,
     then, solely for the purpose of determining the rights of the Participant
     with respect to such Award, a Change of Control shall be deemed to occur at
     the close of business on the first business day following the date on which
     the limitations on such Award under Section 7.02.1 have expired.

     9.02  Creation and Funding of Trust.  Upon the earlier of the occurrence of
a Potential Change of Control or a Change of Control, the Company shall deposit
with the trustee of a trust for the benefit of Participants monies or other
property having a Fair Market Value at least equal to the value of cash, Shares
and other property to be paid or distributed in connection with Awards
outstanding at that date.  The trust shall be a grantor trust which shall
preserve the "unfunded" status of Awards under the Plan.  Subsequent to a
Potential Change of Control which is no longer continuing and prior to any
Change of Control, upon the request of the Company, the trustee shall deliver
the monies or other property held in the trust to the Company.

     9.03  Definition of Certain Terms.  For purposes of this Section 9, the
following definitions, in addition to those set forth in Section 2.01, shall
apply:

           9.03.1  "Change of Control" means and shall be deemed to have

     Act), directly or indirectly, of Voting Securities representing 20 percent
     or more of the total voting power of all the then-outstanding Voting
     Securities, except that there shall be excluded from the number of Voting
     Securities deemed to be beneficially owned by a Person a number of Voting
     Securities representing not more than 10 percent of the then-outstanding
     voting power if such Person is (a) eligible to file a Schedule 13G pursuant
     to Rule 13d-1(b)(1) under the Exchange Act with respect to Voting
     Securities or (b) an underwriter who becomes the beneficial owner of more
     than 20 percent of the then-outstanding Voting Securities pursuant to a
     firm commitment underwriting agreement with the Company; or

           (ii)  the individuals who, as of the effective date of the Plan,
     constitute the Board of Directors of the Company together with those who

     election or nomination for election to the Board was approved by a vote of
     at least a majority of the directors then still in office who either were
     directors as of the effective date of the Plan or whose recommendation,

     "Continuing Directors"), cease for any reason to constitute a majority of
     the members of the Board; or

          (iii)  the stockholders of the Company approve a merger,

<PAGE>
 
     transaction if stockholder approval is not obtained, other than (a) any
     such transaction which would result in at least 75 percent of the total
     voting power represented by the voting securities of the surviving entity
     outstanding immediately after such transaction being beneficially owned by
     at least 75 percent of the holders of outstanding Voting Securities
     immediately prior to the transaction, with the voting power of each such
     continuing holder relative to other such continuing holders not
     substantially altered in the transaction, or (b) any such transaction which
     would result in a Related Party beneficially owning more than 50 percent of
     the voting securities of the surviving entity outstanding immediately after
     such transaction; or

           (iv)  the stockholders of the Company approve a plan of complete
     liquidation of the Company or an agreement for the sale or disposition by

     (ii) in the preceding sentence, the "price paid or offered" will be equal
     to the sum of (i) the face amount of any portion of the consideration
     consisting of cash or cash equivalents and (ii) the fair market value of
     any portion of the consideration consisting of real or personal property
     other than cash or cash equivalents, as established by an independent

     of which would result in the occurrence of a Change of Control; or (ii) any

     Company which carry the right to vote generally in the election of
     directors.

     SECTION 10.  Amendments to and Termination of the Plan.

     10.01  The Board may amend, alter, suspend, discontinue or terminate the
Plan without the consent of stockholders or Participants, except that, without
the approval of the stockholders of the Company, no amendment, alteration,
suspension, discontinuation or termination shall be made if stockholder approval
is required by any federal or state law or regulation, or if the Board in its
discretion determines that obtaining such stockholder approval is for any reason
advisable; provided, however, that, without the consent of the Participant, no
amendment, alteration, suspension, discontinuation or termination of the Plan
may materially and adversely affect the rights of such Participant under any
Award theretofore granted to him.  The Committee may waive any conditions or
rights under, amend any terms of, or amend, alter, suspend, discontinue or
terminate, any Award theretofore granted, prospectively or retrospectively;
provided, however, that, without the consent of a Participant, no amendment,
alteration, suspension, discontinuation or termination of any Award may
materially and adversely affect the rights of such Participant under any Award
theretofore granted to him.

     SECTION 11.  General Provisions.

     11.01  No Rights to Awards; No Stockholder Rights.  Nothing in this Plan
shall give any Participant or employee any right or claim to be granted any
Award under the Plan, and there is no obligation for uniformity of treatment of
Participants and employees.  No Award shall confer on any Participant any of the
rights of a stockholder of the Company unless and until Shares are in fact
issued to such Participant in connection with such Award.

     11.02  Withholding.  The Company or any Affiliate is authorized to withhold
from any Award granted or any payment due under the Plan, including from a
distribution of Shares, amounts of withholding taxes due with respect to an
Award, its exercise or any payment thereunder, and to take such other action as
the Committee may deem necessary or advisable to enable the Company and
Participants to satisfy obligations for the payment of withholding taxes

                                      A-15
<PAGE>
 
and tax liabilities in excess thereof. This authority shall include authority to
withhold or receive Shares, Awards or other property and to make cash payments
in respect thereof in satisfaction of such tax obligations.

     11.03  No Right to Employment.  Nothing contained in the Plan or any Award
Agreement shall confer, and no grant of an Award shall be construed as
conferring, upon any Participant any right to continue in the employ of the
Company or any Affiliate or to interfere in any way with the right of the
Company or any Affiliate to terminate his employment at any time or increase or
decrease his compensation from the rate in existence at the time of granting of
an Award, except as may be expressly provided in any Award Agreement or other
compensation arrangement.

     11.04  Unfunded Status of Awards; Creation of Trusts.  The Plan is intended
to constitute an "unfunded" plan for incentive and deferred compensation.  With
respect to any payments not yet made to a Participant pursuant to an Award,
nothing contained in the Plan or any Award shall give any such Participant any
rights that are greater than those of a general unsecured creditor of the
Company; provided, however, that, in addition to the requirements of Section
9.02, the Committee may authorize the creation of trusts or make other
arrangements to meet the Company's obligations under the Plan to deliver cash,
Shares or other property pursuant to any Award, which trusts or other
arrangements shall be consistent with the "unfunded" status of the Plan unless
the Committee otherwise determines.

     11.05  No Limit on Other Compensatory Arrangements.  Nothing contained in
the Plan shall prevent the Company or any Affiliate from adopting other or
additional compensation arrangements (which may include, without limitation,
employment agreements with executives and arrangements which relate to Awards
under the Plan), and such arrangements may be either generally applicable or
applicable only in specific cases.  Notwithstanding anything in the Plan to the
contrary (other than the provisions of Section 7.02), the terms of each Award
shall be construed so as to be consistent with such other arrangements in effect
at the time of the Award.

     11.06  No Fractional Shares.  No fractional Shares shall be issued or
delivered pursuant to the Plan or any Award.  The Committee shall determine
whether cash, other Awards or other property shall be issued or paid in lieu of
fractional Shares or whether such fractional Shares or any rights thereto shall
be forfeited or otherwise eliminated.

     11.07  Governing Law.  The validity, interpretation, construction and
effect of the Plan and any rules and regulations relating to the Plan shall be
governed by the laws of the State of Delaware (without regard to provisions
governing conflicts of laws) and applicable federal law.

     11.08.  Severability.  If any provision of the Plan or any Award is or
becomes or is deemed invalid, illegal or unenforceable in any jurisdiction, or
would disqualify the Plan or any Award under any law deemed applicable by the
Committee, such provision shall be construed or deemed amended to conform to
applicable laws or if it cannot be construed or deemed amended without, in the
determination of the Committee, materially altering the intent of the Plan, it
shall be deleted and the remainder of the Plan shall remain in full force and
effect; provided, however, that, unless otherwise determined by the Committee,

                                 TRUST AGREEMENT
                                 ---------------


          THIS AGREEMENT, made as of the 1st day of June, 1995, between
CONSOLIDATED NATURAL GAS COMPANY, a corporation organized and existing under the
laws of the State of Delaware (the "Company"), and MELLON BANK, a banking
institution organized and doing business under the laws of the United States
with an office in Pittsburgh, Pennsylvania (the "Trustee").

                                 WITNESSETH:

          WHEREAS, the Company and certain of its subsidiaries have established
and maintain certain unfunded employee benefit plans, agreements and
arrangements for the benefit of a select group of highly compensated management
employees of the Company and its subsidiaries (which plans, agreements and
arrangements are each referred to herein individually as the "Plan" and
collectively as the "Plans").  The Plans are identified in Schedule A hereto,
which includes, inter alia, "Administrative Guidelines" for the determination of
                ----- ----                                                      
Benefits under the Plans and payment thereof from the Trust, and which will be
supplemented annually as provided in Section 4.4(b).  Each of the management
employees entitled to benefits under one or more of the Plans is hereinafter
referred to individually as a "Participant" and collectively as the
"Participants."  Each Plan provides for the payment of certain benefits (the
"Benefits") to certain of the Participants and their beneficiaries, if any,
designated by the respective Participants (or by the Plan) as being entitled to
any payments due under the terms of the Plan in the event of a Participant's
death ("Beneficiary" or "Beneficiaries").  The Company and its subsidiaries have
incurred and expect to continue to incur liabilities pursuant to the terms of
the Plans; and the Company wishes to establish the trust provided for herein
(the "Trust") to aid the Company and its subsidiaries in meeting their
obligations under the Plans.  Moreover, and as provided in detail in the
Administrative Guidelines in Schedule A, the Company intends the assets of each
account established under the Trust ("Account" or "Accounts") to be available to
pay benefits solely to Participants who accrued benefits payable under a Plan or
Plans pursuant to their employment by the Company and/or those subsidiaries
identified in Schedule A.  Except as otherwise provided in the immediately
preceding sentence, the Company intends the assets of the Trust to constitute a
unitary, nonsegmented source of funds 
<PAGE>
 
from which to pay benefits under all of the Plans as if they were a single plan,
with no benefit under any particular Plan having any priority over any other
benefit under that Plan or under any other Plan and with no assets of the Trust
designated to pay any particular benefit.

          The Trust is intended to be a "grantor trust" with the corpus and
income of the Trust treated as assets and income of the Company for federal
income tax purposes pursuant to Sections 671-677 of the Internal Revenue Code of
1986, as amended (the "Code").  The Company intends that the assets of the Trust
will be subject to the claims of creditors of the Company and its subsidiaries
as provided in Article II hereof.  Amounts transferred to the Trust and the
earnings thereon shall be used by the Trustee to satisfy the liabilities of the
Company and its subsidiaries in accordance with the provisions hereof.  Upon
satisfaction of all liabilities of the Company and its subsidiaries with respect
to all Participants and Beneficiaries, the Trust shall terminate and the
remaining assets, if any, of the Trust shall revert to the Company.

          The Company and its subsidiaries intend that the existence of the
Trust shall not alter the characteristics of the Plans as unfunded plans
maintained primarily for the purpose of providing deferred compensation for a
select group of management or highly compensated employees for purposes of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and shall
not be construed to provide income for income tax purposes to any Participant or
Beneficiary under the Plans prior to the actual payment of benefits thereunder.

          NOW, THEREFORE, in consideration of the mutual covenants contained
herein, the Company and the Trustee agree as follows:

                                      -2-

                                 ARTICLE I:  ESTABLISHMENT OF TRUST
                                 ----------------------------------

          1.1   Trust.  The Company hereby establishes a Trust with the Trustee,
                -----                                                           
consisting of such sums of money and other property acceptable to the Trustee as
from time to time shall be paid or delivered to the Trustee, which property may
include life insurance contracts (the "Policies" or "Policy").  All such money
and other property, all investments and reinvestments made therewith, or
proceeds thereof, and all earnings and profits thereon, less all payments and
charges as authorized herein shall constitute the "Trust Fund" or "Fund."  The
Trust Fund shall be held by the Trustee in Trust and shall be dealt with in
accordance with the provisions of this Trust Agreement.

          1.2   Description of Trust.  The Company represents and agrees that
                --------------------                                         
the Trust established under this Agreement is, and is intended to be, a
depository arrangement with the Trustee for the setting aside of cash and other
assets of the Company as and when the Company so determines in its sole
discretion for the meeting of part or all of its future retirement and death
benefit obligations to some or all of the Participants and their Beneficiaries
under the Plans.  Contributions by the Company to the Trust shall be in amounts
determined solely by the Company.  The Trustee has no obligation to determine
the amount of any contribution and, except as provided in Section 5.1, with
respect to drawing upon letters of credit, has no duty to enforce payment of any
contribution.  The Company further represents that the Plans are unfunded
deferred compensation plans for a select group of management or highly
compensated employees, and as such are exempt from the application of ERISA
except for the disclosure requirements applicable to such plans, for which the
Company bears full responsibility as to compliance.  The Company further
represents that the Plans are not qualified under Section 401 of the Code and
therefore, are not subject to any of the Code requirements applicable to tax-
qualified plans.

          1.3   Acceptance by the Trustee.  The Trustee accepts the Trust
                -------------------------                                
established under this Trust Agreement on the terms and subject to the
provisions set forth herein, and agrees to discharge and perform fully and
faithfully all of the duties and obligations imposed upon it under this Trust
Agreement.  The Trustee has no responsibility or duties regarding the
administration of the Plans, except for the duties specifically described in
this Agreement.

                                 ARTICLE II:  CLAIMS OF COMPANY'S CREDITORS
                                 ------------------------------------------

          2.1   No Security Interest.  It is the intent of the parties hereto
                --------------------                                         
that the Trust Fund is and shall remain at all times subject to the claims of
the Company's general creditors in the event of the Company's insolvency or
bankruptcy and that each Account established under the Trust shall remain at all
times subject to the claims of the general creditors of subsidiary(ies) of the
Company which is (are) identified in Schedule A in the event of such
subsidiary's or subsidiaries' insolvency or bankruptcy.  Accordingly, the
Company shall not create a security interest in the Trust Fund in favor of any
Participant or Beneficiary of the Plans or any creditor.

          2.2   Suspension of Payments.  Notwithstanding any provisions in this
                ----------------------                                         
Agreement to the contrary, if at any time while the Trust is still in existence
the Company or a subsidiary identified in Schedule A becomes insolvent or
bankrupt (as defined herein), the Trustee shall upon receipt of written notice
thereof under Section 2.4 suspend the payment of all Benefits from the Fund (in
the event the Company becomes insolvent or bankrupt) or from the Account
identified in Schedule A as relating to such subsidiary (in the event a
subsidiary becomes insolvent or bankrupt) and shall hold the Fund or Account for
the benefit of the Company's or subsidiary's general creditors, and shall
deliver the entire amount of the Trust Fund or Account only as a court of
competent jurisdiction, or duly appointed receiver or other person authorized to
act by such a court, may direct to make the Trust Fund or Account available to
satisfy the claims of the Company's or subsidiary's general creditors.  Unless
the Trustee has actual knowledge of the Company's insolvency or bankruptcy, the
Trustee shall have no duty to inquire whether the Company or subsidiary is
insolvent or bankrupt.

          2.3   Resumption of Payments.  The Trustee shall resume all its duties
                ----------------------                                          
and responsibilities under this Trust Agreement including payments of Benefits
to Participants and Beneficiaries of the Plans within 30 days of the Trustee's
determination that the Company or subsidiary is not insolvent or bankrupt (or is
no longer insolvent or bankrupt).  In making such determination, the Trustee may
retain outside experts competent to advise the Trustee as to whether the Company
or subsidiary has or still is, in fact, insolvent or bankrupt.  The expense of
retaining such outside experts shall be deemed a Trust expense within the
meaning of Section 6.3.

                                      -4-
<PAGE>
 
The first payments to a Participant or Beneficiary, pursuant to a resumption of
payments, following such discontinuance shall include the aggregate amount of
all payments which would have been made to the Participant or Beneficiary in
accordance with the Plans during the period of such discontinuance, less the
aggregate amount of payments of Benefits under the Plans made to the Participant
or Beneficiary by the Company or subsidiary during any such period of
discontinuance.

          2.4   Notice of Insolvency.  By its approval and execution of this
                --------------------                                        
Agreement, the Company represents and agrees that its Board of Directors and
Chief Executive Officer, as from time to time acting, shall have the fiduciary
duty and responsibility on behalf of the Company's creditors to give to the
Trustee prompt written notice of any event of the Company's or a subsidiary's
insolvency or bankruptcy and the Trustee shall be entitled to rely thereon to
the exclusion of all directions or claims to pay Benefits thereafter made.

          2.5   Insolvency.  The Company or subsidiary shall be deemed to be
                ----------                                                  
insolvent or bankrupt upon the occurrence of any of the following:
          (a) The Company or subsidiary is unable to pay its debts as they
fall due; or
          (b) The Company or subsidiary shall make an assignment for the benefit
of creditors, file a petition in bankruptcy, petition or apply to any tribunal
for the appointment of a custodian, receiver, liquidator, sequestrator, or any
trustee for it or a substantial part of its assets, or shall commence any cause
under any bankruptcy, reorganization, arrangement, readjustment of debt,
dissolution, or liquidation law or statute of any jurisdiction (federal or
state), whether now or hereafter in effect; or if there shall have been filed
any such petition or application, or any such case shall have been commenced
against it, in which an order for relief is entered or which remains
undismissed; or the Company or subsidiary by any act or omission shall indicate
its consent to, approval of or acquiescence in any such petition, application or
case or order for relief or to the appointment of a custodian, receiver or any
trustee for it or any substantial part of any of its property, or shall suffer
any such custodianship, receivership, or trusteeship to continue undischarged.

                                 ARTICLE III:  POWERS OF TRUSTEE
                                 -------------------------------
          3.1   Investment of the Trust.
                ----------------------- 
          (a) The Trust Fund shall be invested by the Trustee in accordance with
the written investment guidelines provided from time to time to the Trustee by
the Company or by an investment committee appointed by the Board of Directors of
the Company.  If no such guidelines are received by the Trustee, the assets of
the Trust Fund, other than the Policies, shall be invested in investments
emphasizing safety of principal, such as a short-term income fund maintained by
the Trustee, or in short-term debt securities issued or guaranteed by the U.S.
government, cash equivalents, and the like.  Subject to the foregoing, the
Trustee shall have the power to invest or reinvest assets in the Trust Fund in
any personal or intangible property, without restriction to securities or
property of the character authorized for investments by trustees under any
statute or other laws of any state, district or territory, including without
limitation any of the following:  common or preferred stocks or other evidences
of ownership in any corporation, partnership, mutual fund, investment company,
association, joint venture or business trust; indebtedness issued by
corporations (including those convertible to common stock), or issued or
guaranteed by the United States or any agency or instrumentality thereof, or any
state, municipality or agency or instrumentality thereof; savings accounts,
certificates of deposits and other types of time deposits and other types of
time deposits with any financial institution under the supervision of the United
States or any state, including the Trustee in its corporate capacity or any
affiliate, department or division of the same; or individual or group insurance
policies, including annuity or investment contracts, where directed by the
Company; provided, that permitted investments shall not include any interest,
direct or indirect, in real estate.  Permitted investments shall also include
units in any common, collective or pooled trust fund operated or maintained
exclusively for the commingling and collective investment of monies or other
assets of plans like the Plan, including without limitation any fund operated or
maintained by the Trustee.  Notwithstanding any other provision of this
Agreement, to the extent trust assets are used to acquire units in any
collective trust, the terms and conditions of its trust indenture shall solely
govern the investment duties and responsibilities of the fund trustee, and to
the extent required by law, the terms and conditions of 

                                      -6-
<PAGE>
 
such trust indenture shall be incorporated herein by reference. For purposes of
valuation, the value of the interest maintained by the Trust in such collective
fund shall be the fair market value of the collective fund units held,
determined in accordance with generally recognized valuation procedures. The
Company expressly understands and agrees that any such collective fund may
provide for the lending of its securities by the fund trustee and that such
fund's trustee will receive compensation for the lending of securities that is
separate from any compensation of the Trustee hereunder, or any compensation of
the fund trustee for the management of such fund.
          (b) Notwithstanding anything in the Trust Agreement to the contrary,
(i) the Company shall have the right and power at any time and from time to time
to contribute one or more Policies to the Trust Fund, and to direct the Trustee
to acquire one or more Policies and to pay premiums from the Trust Fund in
accordance with any such Policy, and (ii) except as the Company shall otherwise
direct, the Trustee shall hold each Policy as part of the Trust Fund and shall
neither transfer any Policy, make or cause to be made any loans, withdrawals,
surrenders or other distributions under any Policy, nor surrender, assign,
amend, modify or terminate any Policy; provided, however, the foregoing
notwithstanding, if the Company fails to contribute Qualified Assets to the
Trust pursuant to Section 5.1(c), the Trustee will surrender any or all policies
to obtain cash to pay Benefits to Participants or Beneficiaries; and the Trustee
may make or cause to be made loans, withdrawals, surrenders or other
distributions under any or all Policies, or surrender any Policy, to the extent
necessary to obtain cash to pay administrative expenses.
          (c)  All Policies on the life of a Participant (whether contributed by
the Company or purchased by the Trustee at the Company's direction pursuant to
Section 3.1(b)) shall be held by such Trustee until the death benefit proceeds
of such policy have been duly paid following the Participant's death; or the
Policy has been surrendered in whole or in part for its cash value for the
purpose of paying deferred compensation benefits to the Participant; or
surrendered in whole or in part for its cash value following the Participant's
forfeiture of all or part of the Benefits under a Plan (of which whole or
partial forfeiture the Company shall notify the Participant and the Trustee in
writing).

individual or group annuity contracts and to take such action with respect to
such contracts as necessary to carry out the terms of this Trust Agreement,
including but not limited to payment of insurance premiums, repayment of policy
loans, and complete or partial surrender of such contracts to pay Plan Benefits
or Trust expenses (not otherwise provided for).
          (d) Generally to do all acts, whether or not expressly authorized,
that the Trustee deems necessary or desirable for the protection of the Fund and
to carry out the purposes of this Trust Agreement.

          3.3   Administrative Powers of Trustee.  Except as limited by Section
                --------------------------------                               
3.1 or as otherwise provided in this Trust Agreement, the Trustee shall have the
following administrative powers in its sole and absolute discretion:
          (a) To register or hold any securities or other property held by it in
its own name or in the name of any custodian of such property or of its nominee,

or without the addition of words indicating that such securities are held in a

actuaries,

consultants, and other providers of services, to consult with them with respect
to the implementation and construction of this Trust Agreement, the duties of
the Trustee hereunder, the transactions contemplated by this Trust Agreement or
any act which the Trustee proposes to take or omit, to rely upon the advice of
and services performed by such persons and to pay their reasonable fees,
expenses and compensation from the Trust Fund.
          (c) To exercise any right to draw cash pursuant to a letter of credit
on the Company's account which has been issued in favor of the Trust, as

          (d) To determine whether the Company or a subsidiary is insolvent as
provided in Section 2.5 hereof.
          (e) To transfer excess Trust assets to the Company as provided in

          (f) Generally to do all acts, whether or not expressly authorized,

          3.4   Summary of Plan and Trust Responsibilities.  The Company intends
                ------------------------------------------                      
the assets of each Account under the Trust to be available to pay benefits
solely to Participants who accrued benefits payable under a Plan or Plans
pursuant to their employment by the Company and/or those subsidiaries identified
in Schedule A.  Except as otherwise provided in the immediately preceding
sentence, the Company intends the assets of the Trust to constitute a unitary,
nonsegmented source of funds from which to pay all benefits under all of the
Plans as if they were a single plan, with no benefit under any particular Plan
having any priority over any other benefit under that Plan or under any other
Plan and with no assets of the Trust designated to pay any particular benefit.
The Company further intends that no Plans be subject to the funding and design
requirements of ERISA.  The Company and the Trustee agree that the Trustee has
no duty or obligation to:
           a.   determine the amount of any contribution to the Trust;


                                      -9-
<PAGE>
 
           b.   except as specifically provided in Section 5.1, with respect to
                drawing upon letters of credit,  enforce the payment of any
                contribution to the Trust;
           c.   determine any benefit for any Participant or Beneficiary under
                any Plan; and
           d.   except as otherwise provided in this Section 3.4, make any
                determination as to the allocation of any Trust asset to any
                particular Plan, its Participants or their Beneficiaries.
 
It is understood that the Trustee's only fiduciary obligation is to hold and
manage assets contributed to the Trust in accordance with the provisions of this
Agreement and that the Trustee has no duty or obligation to administer or manage
any provision of any Plan.  All Plan administrative duties are the sole
responsibility of the Company or its duly appointed Plan administrators or
consultants.  In accordance herewith, the Trustee has no duty or obligation to
act except upon the written direction of the Company or its duly appointed Plan
administrators or consultants (which written directions to include the
information in Schedule A as delivered to the Trustee from time to time), and
the Company agrees to indemnify and hold the Trustee unharmed against all loss
or liability (including expenses and reasonable attorneys' fees) to which it may
be subject by reason of any acts taken in accordance with any directions, or
acts omitted to be taken in good faith due to an absence of directions, from the
Company, and all loss or liability arising out of any other action or failure to
act by the Trustee in executing its duties under this Agreement unless
occasioned by the Trustee's own negligence or misconduct.  No Participant,
beneficiary or third party shall have any cause of action against the Trustee
for complying with such written direction.

Notwithstanding anything else in this Agreement to the contrary:  (1) the
Trustee is not a party to, and has no duties or responsibilities under, the
Plan; (2) in any and all cases where the Trustee is required by this Agreement
to act with reference to Plan terms, the Company shall have the responsibility
to certify the relevant provisions to the Trustee in writing, and the Trustee
shall be entitled to rely upon such certification until notified otherwise in
writing by the Company; (3) absent written certification to the Trustee pursuant
to this paragraph, the Trustee shall be

                                      -10-
<PAGE>
 
chargeable with no knowledge of any Plan terms and shall be deemed to be in
compliance with the Plan; and (4) in any case in which a provision of this
Agreement conflicts with any provision in the Plan, this Agreement shall
control. Notwithstanding the preceding sentence, the Trustee reserves the right
to seek a judicial and/or administrative determination as to its proper course
of action under this Agreement.

                         ARTICLE IV:  TRUST OBLIGATION TO PAY PLAN BENFITS
                         -------------------------------------------------

          4.1   Nature of Trust Beneficiaries' Interest.  The establishment of
                ---------------------------------------                       
the Trust and the payment or delivery to the Trustee of assets shall not vest in
any Participant or Beneficiary any right, title or interest in and to any assets
of the Trust.  To the extent that any Participant or Beneficiary acquires the
right to receive payments under a Plan, such right shall be no greater than the
right of any unsecured general creditor of the Company or relevant subsidiary
and such Participant or Beneficiary shall have only the unsecured promise of the
Company or subsidiary that such payments will be made.

          4.2  Obligations.
                ----------- 
          (a) Obligation of Company.  Notwithstanding anything in this Trust
              ---------------------                                         
Agreement to the contrary, the Company shall remain primarily liable to pay Plan
Benefits.
          (b) Obligation of Trustee.  The Trustee shall make cash payments of
              ---------------------                                          
Benefits, or shall transfer ownership of Policies, to Participants and
Beneficiaries at such times and in such amounts as are required of the Company
under the Plans as determined by the Company, or its duly appointed Plan
administrators or consultants, pursuant to Section 4.4 hereof.  The Trustee has
no obligation to determine any Participant's or Beneficiary's Benefits under any
Plan, but, as provided in Section 4.4, may rely on Schedule A for determinations
or instructions regarding the payment of Benefits.  The Trustee does not
guarantee the adequacy of the Trust Fund to meet and discharge any or all of the
Company's liabilities under the Plans, and, except as specifically provided in
Section 5.1 with respect to drawing upon letters of credit, the Trustee has no
obligation to require the Company to provide any funding into the Trust to
discharge such liabilities under the Plans.  The Trustee is not liable for
investment performance or other loss to the Trust Fund except to the extent that
it is judicially determined that it failed to discharge its duties hereunder.

          4.3   Individual Bookkeeping Accounts.  The Trustee shall establish
                -------------------------------                              
and maintain bookkeeping accounts on behalf of the Trust for particular
Participants or Beneficiaries only as directed by the Company.

           4.4  Determination of Benefits Payable to Participants or
                ----------------------------------------------------
Beneficiaries.
- ------------- 
           (a)  Determination of Benefits.
                ------------------------- 
          (1) Prior to a Change in Control (as defined in Section 4.4(f)), the
Company shall be responsible for determining a Participant's eligibility for
benefits under the Plans and the amount and duration thereof, and shall instruct
the Trustee accordingly.  The Trustee shall observe the Company's instructions
unless the Participant or Beneficiary objects thereto and pursues resolution of
the dispute through legal proceedings or arbitration, in which case the Trustee
shall observe the court decree or arbitrator's award in paying benefits (if any
are awarded) to the Participant or Beneficiary.
          (2) After the occurrence of a Change in Control, the Trustee shall pay
benefits to each Participant based on the last accrued benefit data provided to
the Trustee by the Company, pursuant to Section 4.4(b),  prior to the Change in
Control, unless the Company and the Participant agree upon a different benefit
amount, or the Participant or the Company objects thereto and pursues resolution
of the dispute through legal proceedings or arbitration, in which case the
Trustee shall observe the court decree or arbitrator's award in paying benefits
(if any are awarded) to the Participant or Beneficiary.
          (3) A Participant or Beneficiary may apply in writing directly to the
Trustee for payment of a Benefit that (i) has been awarded to the Participant or
Beneficiary by a final court decree or arbitration award, and (ii) has not been
paid by the Company.  Such application shall be accompanied by a certified copy
of such court decree or arbitration award.  Subject to the provisions of Article
II hereof, upon receiving an application for payment of a Benefit accompanied by
a certified copy of a court decree or arbitration award, the Trustee shall
notify the Company of the application, including the amount of the Benefit
payable, and the Trustee shall make such payments as are required by the court
decree or arbitration award, after providing the Company with an opportunity to
prove to the satisfaction of the Trustee that the Company has paid the Benefit
to the Participant or Beneficiary.
          (b) Provision of Accrued Benefit Data to Trustee.  At least annually,
              --------------------------------------------                     
or more frequently, in the Company's sole discretion as determined by the
Company's Annuities and 


                                      -13-
<PAGE>
 
Benefits Committee (the "Committee"), the Committee shall provide, or cause to
be provided, to the Trustee in writing the information described below, which
shall be added to and become a part of Schedule A to this Agreement. Much of
such information depends upon definitions and other provisions of the Plan
documents establishing the respective Plans, and the Company acknowledges that
it is solely responsible for interpreting the Plan documents and determining the
required information on the basis thereof. Such written information, which shall
be certified by the Committee or by the Company's Vice President, Human
Resources, shall set forth the identity of each Participant then participating
in each Plan, together with all data necessary to calculate and pay his or her
benefit under each Plan in which he or she participates, including, without
limiting the generality of the foregoing, the following:
                     .  Name
                     .  Social Security number
                     .  Birth date
                     .  Mailing address
                     .  Direct bank deposit information
                     .  Amount of benefit
                     .  Payment date or dates
                     .  Duration of benefit payments
                     .  Name, Social Security number and birth date of joint
                        annuitant or beneficiary
          (c) In making payment of the Benefits from the assets of the Trust,
the Trustee may rely completely on the information and benefit determinations
provided to it pursuant to Section 4.4(a) and (b) and shall be fully protected
and indemnified by the Company for so doing.  Moreover, the Trustee shall be
under no obligation to commence any action seeking judicial, arbitral or
administrative relief in the event that the Company or the Committee does not
comply with its obligations under Sections 4.4(a) and (b) hereof or the
respective Participants or Beneficiaries do not pursue appropriate legal or
other remedies to resolve any dispute.

                                      -14-
<PAGE>
 
          (d) The Trustee, if so directed by the Company, may also arrange for
the payment of periodic Plan Benefits directly by an insurance Company under the
terms of a Policy (as, e.g., by the periodic partial surrender of insurance 
                       ----
coverage under the Policy to generate cash) or by surrendering the Policy in
exchange for an annuity contract, owned by the Trust, to pay such Plan Benefits.
          (e) Upon the death of a Participant to whom payment of periodic
benefits has begun, with the written agreement of the Company, the Trustee shall
have the right, in its sole discretion, to pay the Participant's Beneficiary the
commuted value of any remaining guaranteed periodic benefits under the Plan in a
single cash lump sum.
          (f) For purposes of this Agreement, a "Change in Control" means and
shall be deemed to have occurred if:
          (1) any person or entity, other than the Company or a Related Party,
is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the
Security Exchange Act of 1934 ("Exchange Act")), directly or indirectly, of
Voting Securities representing twenty percent (20%) or more of the total voting
power of all the then-outstanding Voting Securities, except that there shall be
excluded from the number of Voting Securities deemed to be beneficially owned by
a person or entity a number of Voting Securities representing not more than ten
percent (10%) of the then-outstanding voting power if such person or entity is
(a) eligible to file a Schedule 13G pursuant to Rule 13d-1(b)(1) under the
Exchange Act with respect to Voting Securities or (b) an underwriter who becomes
the beneficial owner of more than twenty percent (20%) of the then-outstanding
Voting Securities pursuant to a firm commitment underwriting agreement with the
Company; or
          (2) the individuals who, as of the effective date of the Plan,
constitute the Board of Directors of the Company together with those who first
become directors subsequent to such date and whose recommendation, election or
nomination for election to the Board was approved by a vote of at least a
majority of the directors then still in office who either were directors as of
the effective date of the Plan or whose recommendation, election or nomination
for


                                      -15-
<PAGE>
 
election was previously so approved (the "Continuing Directors"), cease for
any reason to constitute a majority of the members of the Board; or
          (3) the stockholders of the Company approve a merger, consolidation,
recapitalization or reorganization of the Company, reverse split of any class of
Voting Securities, or an acquisition of securities or assets by the Company, or
consummation of any such transaction if stockholder approval is not obtained,
other than (a) any such transaction which would result in at least seventy-five
percent (75%) of the total voting power represented by the voting securities of
the surviving entity outstanding immediately after such transaction being
beneficially owned by at least seventy-five percent (75%) of the holders of
outstanding Voting Securities immediately prior to the transaction, with the
voting power of each such continuing holder relative to other such continuing
holders not substantially altered in the transaction, or (b) any such
transaction which would result in a Related Party beneficially owning more than
fifty percent (50%) of the voting securities of the surviving entity outstanding
immediately after such transaction; or
          (4) the stockholders of the Company approve a plan of complete
liquidation of the Company or an agreement for the sale or disposition by the
Company of all or substantially all of the Company's assets other than any such
transaction which would result in a Related Party owning or acquiring more than
fifty percent (50%) of the assets owned by the Company immediately prior to the
transaction.

For purposes of this Section 4.4(f), (A) "Related Party" means (i) a majority-
owned subsidiary of the Company, (ii) an employee or group of employees of the
Company or any majority-owned subsidiary of the Company, (iii) a trustee or
other fiduciary holding securities under an employee benefit plan of the Company
or any majority-owned subsidiary of the Company or (iv) a corporation owned
directly or indirectly by the stockholders of the Company in substantially the
same proportion as their ownership of Voting Securities and (B) "Voting
Securities or Security" means any securities of the Company which carry the
right to vote generally in the election of directors.

          The Trustee shall be entitled, at any time and from time to time, to
demand written certification from the Secretary of the Company regarding whether
a Change in Control has occurred.  Pending the receipt of a response,
satisfactory to the Trustee in form and detail, to such


                                      -16-
<PAGE>
 
demand, the Trustee shall assume that a Change in Control has not occurred;
provided, however, that in the event the Trustee, within the ten day period
following such demand by the Trustee, does not receive a written certification
from the Secretary of the Company, satisfactory to the Trustee in form and
detail, that a Change in Control has not occurred, the Trustee shall assume that
a Change in Control has occurred.

          4.5   Payment upon Constructive Receipt.  Notwithstanding any other
                ---------------------------------                            
provision of this Trust Agreement, if any amounts held in the Trust are found
in a "determination" (within the meaning of Section 1313(a) of the Code) to have
been includable in gross income of a Participant or Beneficiary prior to payment
of such amounts from the Trust, the Trustee shall, as soon as practicable, to
the extent the Company has not made such payment from its own assets, pay to
such Participant or Beneficiary an amount equal to the product of (i) the amount
determined to have been includable in gross income in such determination, and
(ii) the sum of the maximum marginal federal, state and local individual income
tax rates, as determined by the Company, in effect with respect to such
Participant or Beneficiary during the taxable year to which the "determination"
applies, and shall both reduce the Participant's or Beneficiary's future
Benefits accordingly and charge the applicable Participant Account of such
Participant or Beneficiary.  The Trustee shall not make any distribution to a
Participant or Beneficiary pursuant to this Section 4.5 unless it has received a
copy of the "determination" described above.  The Company shall be primarily
liable for making the payment described in this Section 4.5.

           5.1  Contributions
                -------------
          (a) The Company shall deliver to the Trustee such cash, Policies or
other property, which may include letters of credit on the Company's account
issued in favor of the Trust by a national bank (which may include the
Commercial Department of the Trustee), as the Company shall from time to time
determine.
          (b) Notwithstanding the foregoing, the Trustee shall not be liable for
any failure by the Company to provide contributions sufficient to pay Benefits
under the Plans in full or to cause required transfers of Qualified Assets to be
made as herein required.
          (c) The term "Qualified Assets" when used in this Trust Agreement
shall refer to cash or cash equivalents; letters of credit on the Company's
account issued in favor of the Trust by a national bank (which may include the
Commercial Department of the Trustee); shares of stock and other securities
readily tradeable on an established national exchange; and such other assets
which the Trustee, in its sole discretion, agrees to accept.

          (d)        (1) If the Trustee is directed to pay benefits under the
Plans from the Trust or the Trustee is due compensation or reimbursement for its
expenses, the Trustee shall for these purposes apply the assets then held in the
Trust in the following order of priority:
                         a. Cash, cash equivalents, stock and other readily
                           tradeable securities;
                         b. Cash available under any letter of credit on the
                           Company's account which has been issued in favor of
                           the Trust;
                         c. Policies, as described in Section 5.1(d)(2).
          (2) At any time or from time to time if the Trustee (having applied
assets in the priority stated in Section 5.1(d)(1)) determines that in order to
generate cash to pay current or future Plan Benefits, it is necessary to
surrender any Policies; or the Trustee determines that in order to generate cash
to pay administrative expenses, it is necessary to either borrow from, withdraw
from, encumber in any manner or surrender all or part of any Policy, 

                                      -18-
<PAGE>
 
including without limitation partial surrenders or distributions of policy
values; the Trustee shall notify the Company in writing of its intention to so
surrender such Policies, or to so borrow, withdraw, encumber or surrender, as
the case may be, and the amount thereof. Thereupon, the Company shall have the
option within 30 days to contribute Qualified Assets to the Trust in the amount
stated in the notice, and the Trustee shall then refrain from making such
complete surrender, loan, withdrawal, encumbrance or partial surrender until
such subsequent time(s), if any, that the Trustee again determines that it is
necessary to either completely surrender, borrow from, withdraw from, encumber
or partially surrender one or more Policies, whereupon the Trustee shall again
give written notice of its intention to borrow, withdraw, encumber or surrender
and the Company shall again have the option to contribute Qualified Assets, in
the manner set forth above in this Section 5.1(d)(1).
          (3) Notwithstanding any other provision in this Trust Agreement, in
the event the Company, upon written notice duly given by the Trustee, does not
exercise its option to contribute Qualified Assets to the Trust in the amount
stated in the Trustee's notice within the time period allowed, the Trustee shall
then be authorized to borrow from, withdraw from, encumber in any manner and/or
surrender all or any of the Policies, in the manner described in 5.1(d)(1), even
if the cash raised therefrom is in excess of the amount stated in such notice.

          5.2   Application of Contributions.  Contributions by the Company as
                ----------------------------                                  
provided for herein shall be applied by the Trustee first to the payment of its
fees and expenses and second to the payment of premiums on Policies held by the
Trust.

          5.3   Recovery of Trust Assets by the Company.
                ----------------------------------------

          Except as provided in Sections 5.4 and 5.5 and Articles II and XI
hereof, the Trust Fund shall be held for the exclusive purpose of providing
Benefits to Participants and their Beneficiaries and defraying expenses of the
Trust in accordance with the provisions hereof.  Accordingly, except as provided
in Sections 5.4 and 5.5 and Articles II and X hereof, no part of the income or
corpus of the Trust Fund shall be recoverable by or for the benefit of the
Company.

          5.4   Transfer of Excess Assets to the Company.  The Company may
                ----------------------------------------                  
withdraw assets from the Trust, under the conditions set forth below, if:
 
          (1) the Company shall deliver to the Trustee the report of an enrolled
actuary determining the present value of all future benefits payable under the
Plan with respect to current Participants, based upon reasonable assumptions
regarding, inter alia, interest, future compensation increases, and post-
retirement mortality, but assuming no turnover or pre-retirement mortality; and
          (2) the assets of the Trust exceed such present value of all
future benefits by more than 25%.

Under such circumstances, the Trustee shall deliver assets of the Trust to the
Company equal to the amount or value requested by the Company, provided,
however, that the remaining assets of each Account in the Trust after such
withdrawal shall be not less in value than 125% of such present value of all
future benefits in each such Account.

          5.5   Company as Owner of Assets.  All assets of the Trust, including
                --------------------------                                     
any allocated to a bookkeeping account for the purpose of paying benefits, are
intended by the Company to satisfy the Company's legal liability under the Plans
in respect of the Participants and their Beneficiaries.  If after payment of or
provision for all Benefits due a Participant or Beneficiary, there is any
balance remaining in a bookkeeping account or there are otherwise excess
proceeds from a Policy, such excess shall  revert to the Company in accordance
with this Trust Agreement.  The Company agrees that all income, deductions, and
credits of each such bookkeeping account belong to it as owner for income tax
purposes and will be included on the Company's income tax returns or any other
required tax returns and will be the sole obligation of and paid by the Company.

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

          6.1   Taxes on Trust.  The Company shall from time to time pay taxes
                --------------                                                
of any and all kinds whatsoever which at any time are levied or assessed upon or
become payable in respect of the Trust Fund, the income or any property forming
a part thereof, or any security transaction pertaining thereto.  The Trustee
shall, at Company expense, contest the validity of such taxes in any manner
deemed appropriate by the Company or its counsel, but only if the Trustee has
received an indemnity bond or other security satisfactory to it to pay any
expenses of such contest.  Alternatively, the Company may itself contest the
validity of any such taxes.

          6.2   Withholding Taxes; Employment Taxes.  Any amounts paid to a
                -----------------------------------                        
Participant or Beneficiary pursuant to Article IV shall be reduced by the amount
of taxes required by law to be withheld, and the Company shall calculate the
amounts to be withheld and shall direct the Trustee with respect thereto.  The
Trustee, in its sole discretion, may either pay such taxes required to be
withheld to the Company, whereupon the Company shall have full responsibility
for the payment of all withholding taxes to the appropriate tax authorities, or
pay such taxes directly for the benefit of the Company; in either such event,
the Company shall timely furnish each Participant or Beneficiary with the
appropriate tax information form evidencing such payment and the amount thereof.
The Company shall be solely responsible for calculating and paying employment
taxes (e.g., employer FICA, FUTA, state unemployment), if any, attributable to
Trust payments to Plan Beneficiaries.

          6.3   Expenses and Compensation.  The Trustee shall be paid
                -------------------------                            
compensation by the Company (or, in the event the Company fails to make such
payments, from the Trust Fund), in accordance with the Trustee's regular
schedule or fees for trust services and applicable investment management
services for similar trusts, as in effect from time to time, unless the Company
and the Trustee otherwise agree.  The Trustee shall be reimbursed by the Company
(or in the event the Company fails to make such reimbursement, from the Trust
Fund), for the Trustee's reasonable expenses of management and administration of
the Trust, including reasonable compensation of counsel and any actuary,
consultant or other agent engaged by the Trustee to assist it in such management
and administration.  The Trustee shall submit to the Company a statement for its
compensation and expense reimbursement, setting forth adequate detail to
establish the basis

                                      -21-

therefor. The Trustee shall claim expenses and compensation to be paid from the
Accounts established in the Trust Fund based on the relative value of assets
held in each such Account in the Trust Fund, first from assets not allocated to
separate bookkeeping accounts established under Section 4.3 for the payment of
Benefits; and if such unallocated assets are insufficient, then from assets
which have been allocated under Section 4.3.

                                 ARTICLE VII:  ADMINISTRATION AND RECORDS
                                 ----------------------------------------

          7.1   Records.  The Trustee shall keep or cause to be kept accurate
                -------                                                      
and detailed accounts of any investments, receipts, disbursements and other
transactions hereunder, and all accounts, books, and records relating thereto
shall be open to inspection and audit at all reasonable times by any person
designated by the Company.  All such accounts, books, and records shall be
preserved (in original form, or on microfilm, magnetic tape, or any other
similar process) for such period as the Trustee may determine, but the Trustee
may only destroy such accounts, books, and records after first notifying the
Company in writing of its intention to do so and transferring to the Company any
of such accounts, books, and records requested.

          7.2   Settlement of Accounts.  Within 60 days after the close of each
                ----------------------                                         
calendar year, and within 60 days after the removal or resignation of the
Trustee or the termination of the Trust, the Trustee shall file with the Company
a written account setting forth all investments, receipts, disbursements and
other transactions effected by it during the preceding calendar year, or during
such period from the close of the prior calendar year, to the date of such
removal, resignation, or termination, including a description of all investments
and securities purchased and sold, with the cost or net proceeds of such
purchases or sales, and showing all cash, securities, and other property held at
the end of such calendar year or other period.  Each account so filed shall be
open to inspection at the office of the Trustee during normal business hours by
the Company and by any person appointed in writing by a majority of the
Participants identified in the last preceding annual accrued benefit information
provided to the Trustee pursuant to Section 4.4(c). For purposes of any such
appointment, each Participant shall have one "vote", irrespective of how many of
the Plans he participates in, and multiple beneficiaries of a single deceased
Participant shall share one vote.  (Hereinafter, such person, if any is so
appointed, is referred to as "the Participant's representative".)

          If within 90 days after the filing of such account neither the Company
nor the Participants' representative, if any, has filed with the Trustee notice
of any objection to any act or transaction of the Trustee, the initial account
shall become an account stated as between the Trustee, the Company, and all
persons having or claiming to have an interest in the Trust Fund.  If


                                      -23-
<PAGE>
 
any objection has been filed, and if the Company or the Participants'
representative who filed such objection is satisfied that it should be
withdrawn, the objecting party shall in writing filed with the Trustee signify
its approval of the account, and it shall become an account stated as between
the Trustee, the Company, and all persons having or claiming to have an interest
in the Trust Fund. If the account is adjusted following an objection thereto,
the Trustee shall file with the Company and make available for inspection by the
Participants' representative the adjusted account, and if within 30 days after
such filing of an adjusted account neither the Company nor the Participants'
representative, if any, has filed with the Trustee notice of any objection to
the transactions as so adjusted, the adjusted account shall become an account
stated as between the Trustee, the Company, and all persons having or claiming
to have an interest in the Trust Fund.

          When an account is stated it shall be finally settled, and the Trustee
shall, to the maximum extent permitted by applicable law, be forever released
and discharged from all liability and accountability with respect to the
propriety of its acts and transactions shown in such account.

          7.3   Audit.  The Trustee shall from time to time permit an
                -----                                                
independent certified public accountant selected by the Company to have access
during ordinary business hours to such records as may be necessary to audit the
Trustee's accounts.

          7.4   Judicial Settlement.  Nothing contained in this Trust Agreement
                -------------------                                            
shall be construed as depriving the Trustee or the Company of the right to have
a judicial settlement of the Trustee's account.

          7.5   Delivery of Records to Successor.  In the event of removal or
                --------------------------------                             
resignation of the Trustee, the Trustee shall deliver to the successor Trustee
all records which shall be required by the successor Trustee to enable it to
carry out the provisions of this Trust Agreement.

          7.6   Tax Filings.  In addition to any returns required of the Trustee
                -----------                                                     
by law, the Trustee shall prepare and file such tax reports and other returns as
the Company and the Trustee may from time to time agree.

                                 --------------------------------------------
           8.1  Resignation.
                ----------- 
          (a) The Trustee may resign at any time upon 90 days prior written
notice.  If such resignation occurs prior to a Change in Control, the Trustee's
notice thereof shall be to the Company, and the Company shall make a good faith
effort, following receipt of notice of resignation from the Trustee, to find and
to appoint a successor trustee which is a bank or trust Company with assets in
excess of $2 billion and net worth in excess of $100 million, and which shall
adhere to the obligations imposed on the Trustee under the terms of the Trust
Agreement.  If such resignation occurs after a Change in Control, the Trustee's
written notice thereof shall be to both the Company and to each Plan Participant
whose home address is identified on the last written data on Plan Participants
provided to the Trustee by the Company prior to the Change in Control.  In such
case, a successor Trustee may be appointed pursuant to the written agreement of
at least 25% of the Participants (including Beneficiaries of deceased
Participants) in the Plans.  (For purposes of Section 8.1, multiple
Beneficiaries of a single Participant shall count as one vote.)
          (b) In the event that the Company or at least 25% of Plan
Participants, as the case may be, shall fail to appoint a successor trustee
within 90 days of the Trustee's notice of resignation, the Trustee shall be
entitled to seek judicial removal and appointment of a successor trustee which
is a bank or trust Company with assets in excess of $2 billion and a net worth
in excess of $100 million.
          (c) In any event, the Trustee shall continue to be custodian of the
Trust Fund until the new trustee is in place, and the Trustee shall be entitled
to expenses and fees through the later of the effective date of its resignation
as Trustee or the end of its custodianship of the Trust Fund.

           8.2  Removal.
                ------- 
          (a) Prior to a Change in Control, the Company may remove any Trustee
with or without cause at any time upon at least 90 days notice in writing to the
Trustee.  Such removal of the Trustee by the Company shall not be effective
until the Company has 

                                      -25-
<PAGE>
 
appointed, in writing, a successor Trustee, which must be a bank or trust
Company with assets in excess of $2 billion and a net worth in excess of $100
million, and such successor has accepted the appointment in writing.
          (b) After a Change in Control shall have occurred, a Trustee may be
removed with or without cause at any time upon at least ninety (90) days notice
in writing to the Trustee pursuant to the written agreement of at least 25% of
the Participants in the Plans as of the date preceding the effective date of a
Change in Control, who shall appoint a successor Trustee satisfying the
requirements set forth in Section 8.2(a).  Alternatively, at least 25% of the
Participants in the Plans as of the date preceding the effective date of a
Change in Control may petition the Orphans Court Division, Court of Common
Pleas, Allegheny County, Pennsylvania, for appointment of a successor Trustee.

          8.3   Successor Trustee.  All of the provisions set forth herein with
                -----------------                                              
respect to the Trustee shall relate to each successor trustee with the same
force and effect as if such successor had been originally named as the Trustee
hereunder.

          8.4   Transfer of Trust Fund to Successor.  Upon the resignation or
                -----------------------------------                          
removal of the Trustee and appointment of a successor, the Trustee shall
promptly transfer and deliver the Trust Fund to such successor, the Trustee's
responsibility hereunder shall be limited to managing the assets in its
possession and transferring such assets to the successor, and settling its final
account.  Neither the Trustee nor the successor shall be liable for the acts of
the other.

          9.1   The Company shall have the right to enforce any provision of
this Trust Agreement and either the Trustee on behalf of Participants and
Beneficiaries or any Participant (or the Participant's designated beneficiary
or, absent such designation, the legal representative of the Participant's
estate) as a Beneficiary of the Trust shall have the right to enforce any
provision of this Trust Agreement that affects the right, title, and interest of
such Participant (or other person) in the Trust.  In any action or proceeding
affecting the Trust the only necessary parties shall be the Company, the
Trustee, and the Participants and, except as otherwise required by applicable
law, no other person shall be entitled to any notice or service of process.  Any
judgment entered in such an action or proceeding shall, to the maximum extent
permitted by applicable law, be binding and conclusive on all persons having or
claiming to have any interest in the Trust.  Time is of the essence of this
Agreement and in case any provision of this Agreement is enforced by the Trustee
or by any Participant or Beneficiary by law or through an attorney-at-law, or
under advice therefrom, then the Company shall pay all costs of such enforcement
of collection, including reasonable attorney's fees.

Trustee, after its final account has been settled as provided in Section 8.2,
shall distribute to the Company the net balance of any assets of the Trust
remaining after all Benefits and expenses have been paid.

          10.2  No Further Liability.  Upon making distribution of the Trust
                --------------------                                        
Fund pursuant to the preceding paragraphs of this Article X, the Trustee shall

shall continue so long as any assets of the Trust Fund remain in its hands.

providing deferred compensation for select group of management or highly
compensated employees for purposes of ERISA, the Code, or any other applicable
law; to maintain the Trust as a "grantor trust", and insure that contributions
to the Trust by the Company will not constitute a taxable event and income and
gains of the Trust Fund will not be taxable as income and gains to the Trust or

Trust Fund will be deductible by the Company in the year of payment; and to
effectuate compliance with any other applicable legal requirements.

Notes:
(1) This calculation is submitted in accordance with Regulation S-K Item
    601(b)(11) although not required by footnote 2 to paragraph 14 of APB
    Opinion No. 15 because it results in dilution of less than 3%.
(2) This calculation is submitted in accordance with Regulation S-K Item
    601(b)(11) although it is contrary to paragraph 40 of APB Opinion No. 15
    because the assumed conversion of the 7 1/4% Convertible Subordinated
    Debentures produces an antidilutive result.

                                December 31, 1996
                      ----------------------------------

Gentlemen:

          Consolidated Natural Gas Company, through its subsidiaries
(collectively Consolidated or the Company) is engaged in exploring for,
developing, producing, purchasing, gathering, transporting, storing and
distributing natural gas, together with by-product operations.  The principal
market area of the Company's retail operations is in Ohio, Pennsylvania,
Virginia and West Virginia.  Consolidated operates a regional interstate
pipeline system that supplies natural gas to affiliates, and to utilities and
end-users in the Midwest, Mid-Atlantic states and the Northeast.  Exploration
and production activities are carried on primarily in the Appalachian area, the
Gulf Coast area (including offshore), the Mid-Continent area, the Permian Basin
area, the Rocky Mountain area and in Canada.

          The history of the operations in the Appalachian area covers a period
of over 100 years.  Prior to l943, Consolidated's gas supply was obtained from
company-owned production and by purchase from fields located within the
Appalachian area.  From 1943 to 1993 Consolidated purchased gas from pipeline
companies which obtained their gas supply from fields in the Gulf Coast and
Southwest.  Since 1993, however, all remaining long-term gas purchase contracts
with pipelines have been replaced with firm transport contracts as the result of
Federal Energy Regulatory Commission (FERC) Order 636. Consolidated purchases
gas under contracts with producers and marketers, and also purchases gas on the
spot market. A substantial part of

                                                                          Page 2
 
these gas supplies are also obtained from fields in the Gulf Coast and
Southwest. Since 1957 Consolidated has also been engaged in exploration and
production of gas in Louisiana and the Texas Gulf Coast, including offshore.
During the twelve months ended December 31, 1996 most of the gas produced and
purchased by the Company was obtained from the Southwest. All gas volumes herein
are stated at a measuring base of 14.73 pounds per square inch absolute.

                           APPALACHIAN AREA RESERVES
                           -------------------------

          Studies of the natural gas available from Appalachian gas fields lead
us to conclude that the Company may expect to obtain for a number of years a
supply from this area.  The development which has occurred in this natural gas
province has resulted in extensive drilling of shallow formations in much of the
area.  The entire sedimentary section has not been adequately tested in the
Appalachian area and there is the possibility that natural gas is present in
commercial quantities below the known producing formations.  Consolidated has
participated in programs to test deeper formations.  Consolidated has also found
that reentry into old wells has been beneficial in finding commercial quantities
behind pipe.

          We estimate Consolidated's proved reserves in the Appalachian fields,
as of December 31, 1996, to be 300 billion cubic feet (including CNG Producing
Company's Appalachian reserves) from company-owned wells and 381 billion cubic
feet from gas purchase wells, for a total of 681 billion cubic feet, exclusive
of gas in storage reservoirs.  Total additions to the reserves controlled by the
Company in the Appalachian fields have in the past been substantial.  It is
possible that future exploration and development will locate appreciable new
reserves.  In addition, subsidiary companies had remaining working interest oil
reserves estimated at 393,161 barrels (including CNG Producing Company's
Appalachian oil reserves) in the Appalachian area.


                             CNG PRODUCING COMPANY
                             ---------------------

          CNG Producing Company is Consolidated's primary exploration and
production subsidiary.  As of December 31, 1996, the estimated proved working
interest reserves of CNG Producing Company are 892 billion cubic feet of gas and
50,273,717 barrels of crude oil and

condensate. The foregoing totals include approximately 1 billion cubic feet of
gas and 8,638,612 barrels of heavy oil reserves in Canada.

          In the United States, CNG Producing Company has proved reserves in 10
states and the offshore area of the Gulf Coast.  The majority of CNG Producing
Company's United States reserves are in the Gulf Coast and Mid-Continent areas.
The estimated proved reserves in the United States are 891 billion cubic feet of
gas and 41,635,105 barrels of crude oil and condensate.

          The estimated Appalachian proved reserves as of December 31, 1996 for
CNG Producing Company, which are included in the total Appalachian reserves
disclosed earlier in this report, are 109 billion cubic feet of gas and 101,350
barrels of oil.  In addition to the Appalachian area, CNG Producing Company
conducts exploration and development programs in other areas, including the San
Juan Basin in New Mexico.  The San Juan Basin has a history of oil and gas
production from conventional sources, but recent interest in the area stems from
an unconventional source of gas supply.  This interest is the Fruitland Coal
formation, where CNG Producing Company and others are producing gas from the
coal beds.  The estimated San Juan Basin proved reserves of CNG Producing
Company as of December 31, 1996 are 9 billion cubic feet.

                                 SOUTHWEST GAS
                                 -------------

          Consolidated's subsidiaries have gas supply contracts with various gas
producing companies and marketing groups with remaining terms ranging from a few
months to as long as eight (8) years.  Purchase entitlements under these
contracts total approximately 284 billion cubic feet, if all volumes are
requested.  This estimate gives no consideration to the estimated volumes of
spot market gas which may be purchased in the future.

                                  GAS STORAGE
                                  -----------

          The Company owns and operates 26 gas storage fields, five of which are
owned and operated jointly with other companies.  One storage field is owned and
operated jointly with Texas Eastern, one with Tennessee, one with North Penn
Gas, one with both Tennessee and

National Fuel Gas Supply Corporation, and another with both Texas Eastern and
Transcontinental. Consolidated's net injected gas stored at December 31, 1996,
was 479 billion cubic feet (including 53 billion cubic feet of remaining non-
recoverable native gas, and 60 billion cubic feet of non-recoverable base gas.)

          The proximity of these storage fields to principal markets and their
high deliverability are important factors in enabling the Company to meet peak
loads and daily requirements during the heating season, and permit the gas
purchased to be taken relatively uniformly in summer and winter.

          There are additional depleted, or nearly depleted, gas fields in the
Appalachian area which can be converted to storage fields if needed.
 
                            POTENTIAL SUPPLY SOURCES
                            ------------------------

          In order to meet the demands for gas in its market area over the long-
term future, Consolidated may need additional supplies over those available from
the sources discussed above.

          Canadian authorities have increased the volumes of gas which may be
imported into the United States.  Gas presently being imported from Canada is
principally obtained from provinces in Western Canada.  In the future, the
availability of additional gas will probably be dependent on gas from frontier
areas such as the MacKenzie Basin - Beaufort Sea area and/or the Arctic Islands.
Such additional gas from Canada may be available in part to Consolidated
directly or through other suppliers.

          Other potential sources of gas include Alaska, Mexico, liquefied
natural gas from abroad, synthetic gas from coal or other feed stock and
additional coalbed methane.
 
                            SUMMARY AND CONCLUSIONS
                            -----------------------

          We have estimated proved working interest crude oil and condensate
reserves owned by Consolidated from sources in the United States and Canada at
50,565,528 barrels as of December 31, 1996 as follows:

</TABLE>


          Consolidated's requirements for the twelve months ended December 31,
1996, including sales of gas produced in Canada, were approximately 744 billion
cubic feet, compared to requirements of 897 billion cubic feet in 1995.

          Additional supplies are expected to become available from the
Appalachian area, the Gulf Coast and other areas and from company-owned
reserves.

          Potential sources of supply include additional gas from Canada, Mexico
and Alaska, liquefied natural gas from abroad, gas from the reforming of liquid
hydrocarbons such as naphtha and oil, gas from coal gasification and coalbed
methane.

          The time at which these additional supplies will become available
cannot be definitely predicted.  However, Consolidated is in a favorable
position to secure gas supplies from many directions, including its proven
reserves, the volume of gas in underground storage, the prospects for additional
supplies from its traditional supply areas, the several potential supply sources
and the Company's own program to augment its supply.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
RESULTS OF OPERATIONS
 
NET INCOME
Net income in 1996 was $298.3 million, or $3.16 a share, compared with net
income of $21.3 million, or $.23 a share, in 1995. Net income in 1994 was
$183.2 million, or $1.97 a share.

Earnings for both 1995 and 1996 reflect the impact of special charges in those
years. Excluding the impact of charges related to workforce reduction programs
totaling $9.9 million after taxes, or $.10 a share, 1996 net income would have
been $308.2 million, or $3.26 a share. Earnings for 1995 included the effects
of three special charges. During the first quarter, the Company recorded a
non-cash charge to write down the cost of gas and oil producing properties,
amounting to $145.0 million after taxes, or $1.56 a share. In the second
quarter, the Company recognized a non-cash charge of $20.3 million after
taxes, or $.22 a share, in connection with a write-down of coal properties. In
addition, during 1995 the Company recorded charges totaling $25.6 million
after taxes, or $.27 a share, for workforce reductions. Excluding these
special items, net income for 1995 would have been $212.3 million, or $2.28 a
share. Reference is made to Notes 3 and 4 to the consolidated financial
statements, pages 27 and 28, for details of the special charges recognized in
1995 and 1996.

Higher wellhead prices for natural gas and oil, increased gas and oil
production, colder weather, cost controls and the full year impact of new
rates in place for most of the Company's gas distribution customers
contributed to the improved results for 1996. Weather in the Company's retail
service areas was 5.6 percent colder than normal and 5.5 percent colder than
1995. Normal weather represents a measure of temperature experienced over an
historical time frame, the length of which may differ depending on the
regulatory jurisdiction.

During 1995, the favorable effects of new rates in place for most of the
Company's gas distribution and transmission customers, colder weather and
lower aggregate wage and benefit costs in the latter part of the year
resulting from the workforce reduction programs more than offset the impact of
continued low wellhead prices for natural gas and lower gas and oil
production. Weather in the Company's retail service territories was .5 percent
colder than normal and 2.2 percent colder than in 1994.

Warmer than normal weather, higher operating costs, lower average wellhead gas
prices, reduced gas production and higher interest expense affected results
for 1994.
 
OPERATING REVENUES
Operating revenues include revenues from gas and oil sales, transportation and
storage of gas, brokering activities, by-product operations and, beginning in
1995, wholesale electric sales. Total operating revenues in 1996 were $3,794.3
million, an increase of $487.0 million compared to 1995 operating revenues of
$3,307.3 million.

Regulated gas sales revenues of $1,752.2 million in 1996 were up $154.8
million compared to 1995, with sales volumes increasing 4.1 billion cubic feet
(Bcf) to 294.0 Bcf. Revenues and volumes from the Company's residential
customers increased in 1996 reflecting colder weather compared to 1995, while
revenues and volumes declined for the industrial customer class. While gas
sales volumes for the Company's commercial customer group declined in 1996,
revenues increased compared to 1995 reflecting higher average sales rates.

Nonregulated gas sales revenues increased $94.8 million in 1996, while sales
volumes decreased 160.5 Bcf compared to 1995. The effect of higher gas sales
prices, coupled with the impact of higher production, more than offset the
effect of reduced transaction volumes of the energy marketing services
component.

Gas transportation and storage revenues increased $8.7 million in 1996
compared to the prior year, to $465.1 million. The increase was due to higher
gas transportation revenues, which increased $13.4 million due to higher
volumes and rates. Lower storage service revenues partly offset this increase.
Other operating revenues increased $228.7 million in 1996 to $484.5 million.
The increase over 1995 was due
 
                                       1
<PAGE>
 
chiefly to an increase of $108.8 million in revenues from oil and condensate
production and brokering from the exploration and production operations and an
additional $87.7 million of wholesale electric sales by the energy marketing
services component.

Total operating revenues in 1995 increased $271.3 million from $3,036.0
million in 1994. Regulated gas sales revenues in 1995 decreased $81.9 million
from 1994, to $1,597.4 million, with sales volumes increasing 4.9 Bcf to 289.9
Bcf. Colder weather compared with 1994 led to the increase in sales volumes
while lower unit purchased gas costs reflected in revenues was responsible for
the decline in sales revenue. Nonregulated gas sales revenues increased $274.1
million in 1995, with sales volumes increasing 223.8 Bcf over the 1994 period
to 556.6 Bcf. These increases were attributable to the growth of the Company's
energy marketing services component. The increased volumes sold more than
offset the effects of lower wellhead prices and production at the exploration
and production operations. Gas transportation and storage revenues were $456.4
million in 1995, up $46.8 million over 1994. The increase was due principally
to higher transportation revenues, which increased $39.5 million due to both
increased volumes and rates. Other operating revenues increased $32.3 million
in 1995, to $255.8 million, reflecting wholesale sales of electricity of $21.8
million by the energy marketing services component.
 
OPERATING EXPENSES
Operating expenses, including taxes, increased 8 percent in 1996, to $3,402.1
million. Operating expenses in 1995 were $3,160.8 million, up 14 percent from
$2,775.1 million in 1994. Excluding the impact of the workforce reduction
charges in 1996 and 1995 and the impairment of gas and oil producing
properties in 1995, operating expenses for 1996 and 1995 would have been
$3,392.2 million and $2,990.2 million, respectively.

Purchased gas consistently represents the largest operating expense item for
the Company. Purchased gas costs were $1,615.0 million in 1996, $1,590.1
million in 1995 and $1,424.0 million in 1994. This expense is influenced
primarily by changes in gas sales requirements, the price and mix of gas
supplies, and the timing of recoveries of deferred purchased gas costs. During
1996, the effect of higher average purchase prices more than offset the impact
of decreased volume requirements in connection with nonregulated gas sales and
the deferral of purchased gas costs by the regulated subsidiaries. Total
purchased gas expense was higher in 1995 due primarily to increased volume
requirements associated with nonregulated gas sales. This factor more than
offset lower unit purchased gas costs, which reflected the nationwide decline
in gas prices during 1995.

Transport capacity and other purchased products expense includes the cost of
pipeline capacity not associated with gas purchased and the cost of liquids,
by-products and, beginning in 1995, electricity purchased for resale. This
expense increased $193.1 million in 1996 due chiefly to electricity purchased
for resale by the energy marketing services component and oil purchased for
resale by CNG Producing Company (CNG Producing). This expense increased $46.5
million in 1995 primarily due to increased transport capacity purchased from
other pipeline companies and electricity purchased for resale totaling $19.6
million.

Excluding the effect of the 1996 and 1995 workforce reduction charges of $15.2
million and $42.6 million, respectively, combined operation and maintenance
expense increased $77.2 million in 1996 due in large part to increased royalty
expense in 1996 resulting from higher gas and oil wellhead prices and
production. The increase in 1996 was partially offset by lower payroll costs
and reductions in certain administrative expenses. Maintenance expense
increased $4.2 million in 1996 to $90.1 million.

Excluding the effect of the workforce reduction charges, combined operation
and maintenance expense increased $7.5 million in 1995. Higher customer-
related expenses, slightly higher overhead costs and the regulator-mandated
adjustment for certain previously deferred costs in connection with the
settlement of CNG Transmission Corporation's (CNG Transmission) rate case were
factors contributing to the $10.8 million increase in operation expense. Lower
royalties paid as a result of both lower gas wellhead prices and production
and the benefits of the workforce reduction programs in the latter part of
1995 helped to minimize the increase. Maintenance expense declined $3.3
million, to $85.9 million, in 1995.
 
                                       2
<PAGE>
 
Total depreciation and amortization expense increased $47.6 million in 1996
due largely to higher gas and oil production volumes. Depreciation and
amortization charges were down $22.7 million in 1995 due to lower amortization
charges for the Company's exploration and production operations. Amortization
of gas and oil producing properties declined in 1995 primarily as the result
of the lower investment following the impairment of these properties in the
first quarter. Reserve additions and lower production also contributed to the
lower charges in 1995. Depreciation expense for the regulated subsidiaries was
higher in both 1996 and 1995 due principally to the increased level of plant
investment.

Taxes, other than income taxes, decreased $.7 million in 1996 due in large
part to lower excise and payroll taxes and decreased $.9 million in 1995 due
chiefly to lower revenue-based taxes.

Income taxes increased $152.8 million in 1996 compared to 1995 due to higher
pretax earnings. Income taxes decreased $79.4 million in 1995 compared to the
prior year due mainly to lower pretax earnings.
 
OTHER INCOME
Total other income was $9.3 million in 1996, compared to total other
deductions of $20.5 million in 1995 and total other income of $9.7 million in
1994. Excluding the write-down of coal properties of $31.3 million, 1995 total
other income would have been $10.8 million. Interest revenues declined $6.8
million in 1996 compared to the prior year due largely to the lower level of
temporary cash investments in 1996. Interest revenues increased $4.1 million
in 1995 due primarily to the higher level of temporary cash investments during
that year. Interest revenues were up $1.7 million in 1994, reflecting CNG
Transmission's billing of Federal Energy Regulatory Commission (FERC) Order
636 transition costs in late 1993 and August 1994. The increase in "Other-net"
of $5.4 million in 1996 compared to 1995 reflects increased earnings from the
Company's equity investments and losses related to minor property dispositions
at certain regulated subsidiaries in 1995 that did not recur in 1996,
partially offset by a charge of $5.0 million recognized in connection with an
early extinguishment of debt in December 1996. The decline in "Other-net" in
1995 compared to 1994 was due largely to the property dispositions in that
year.
 
INTEREST CHARGES
Interest on long-term debt increased $6.0 million in 1996 due primarily to
debenture sales of $150 million each in April 1995, October 1996 and December
1996. Interest on long-term debt was up $7.0 million in 1995 due chiefly to
interest expense related to the April 1995 debenture issuance. Other interest
expense declined $7.5 million in 1996 compared to the prior year due largely
to lower interest expense related to customer refunds. Other interest expense
increased in 1995 as a result of higher interest rates on commercial paper
borrowings. The amounts of interest expense capitalized in 1996 and 1995 were
lower than in 1994 due to the lower investment in unproved properties held by
the exploration and production operations.
 
FOURTH QUARTER RESULTS
The Company's net income for the fourth quarter of 1996 was $88.0 million
compared with $87.4 million earned in the 1995 fourth quarter, an increase of
$.6 million. On a per share basis, the 1996 quarter was $.93 compared with
$.94 in 1995. The 1996 quarter, however, reflects special charges for
workforce reductions totaling $7.8 million after taxes, or $.08 per share. The
Company's average gas wellhead price was $2.62 per thousand cubic feet (Mcf),
up $.51 per Mcf compared with the 1995 quarter, while gas production increased
40 percent over 1995. These positive factors were partially offset by the
effect of weather which was 7.8 percent warmer than in the 1995 fourth quarter
and the charge recognized in connection with an early extinguishment of debt
(see "Capital Resources and Liquidity," page 13).

NEW ACCOUNTING STANDARDS
Effective January 1, 1996, the Company adopted the provisions of Statement of
Financial Accounting Standards (SFAS) No. 121, "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." The
adoption of SFAS No. 121 did not have a material effect on the Company's
financial position, results of operations or cash flows. Reference is made to
Note 1 to the consolidated financial statements, page 23, regarding SFAS No.
121.

In October 1995, the Financial Accounting Standards Board (FASB) issued SFAS
No. 123, "Accounting for Stock-Based Compensation." Although the Company has
not changed its accounting method for stock-based compensation as permitted by
this standard, it has included the disclosures pursuant to SFAS No. 123 in
Note 10 to the consolidated financial statements, page 34.
 
COMPONENTS OF THE BUSINESS
Due to the regulated nature of the distribution and transmission components of
the Company's business, operating results can be affected by regulatory delays
when price increases are sought through general rate filings to recover
certain higher costs of operations. Weather is also an important factor since
a major portion of the gas sold or transported by the distribution and
transmission operations is ultimately used for space heating.

The following presents the operating results for each of the Company's
business components. Reference is made to Note 18 to the consolidated
financial statements, page 43, for additional disaggregated information
pertaining to the Company's operations.

DISTRIBUTION
"Distribution" represents the results of the five retail gas distribution
subsidiaries, including their minor gas and oil production activities.
Effective January 1, 1997, West Ohio Gas Company (West Ohio Gas) was merged
with The East Ohio Gas Company (East Ohio Gas)(see "State Regulatory Issues,"
page 12).

Sales growth in the Company's residential service areas in Ohio, Pennsylvania
and West Virginia has generally been limited since such areas have experienced
minimal population growth, and the vast majority of households in these areas
already use natural gas for space heating. Opportunity for growth in the
retail sales market is expected to continue at Virginia Natural Gas, Inc.
(Virginia Natural Gas), due to customer conversions from other energy sources
and the past and potential future expansion of its service territory. Since
the Company's acquisition of this subsidiary in 1990, it has experienced an
annual customer growth rate of about 4 percent, well above the 1 percent rate
for the other distribution subsidiaries.

Similar to the unbundling in recent years of the services provided by gas
pipeline companies, gas distribution companies are now preparing for the
expected deregulation and unbundling of the retail energy market. To this end,
on September 25, 1996, East Ohio Gas filed a proposal with the Public
Utilities Commission of Ohio (PUCO) to permit open access for all of its Ohio
customers. If approved, open access service to customers who do not already
have such an option--small business and residential customers--would be phased
in. Under open access programs, natural gas suppliers other than the local gas
utility can use the utility's existing lines to deliver gas to customers.
Under this proposal, Ohio customers would also have the option of continuing
to purchase natural gas from East Ohio Gas. In addition, The Peoples Natural
Gas Company (Peoples Natural Gas) plans to open its system to customer choice
in Pennsylvania during the spring of 1997. Peoples Natural Gas has begun a
customer information campaign to educate customers about their new options for
unbundled service.

In addition to the initiatives at East Ohio Gas and Peoples Natural Gas, in
early 1997 the Company formed a new nonregulated unit, CNG Retail Services
Corporation. This subsidiary was created to market natural gas, electricity,
and related products and services to residential, commercial and small
industrial customers, including those within the Company's traditional service
territories. This new subsidiary is expected to enable the Company to take
full advantage of emerging deregulated energy markets for both gas and
electricity.

  OPERATING INCOME BEFORE INCOME TAXES
Excluding workforce reduction charges amounting to $8.2 million in 1996 and
$22.3 million in 1995, operating income before income taxes for the gas
distribution operations for 1996 and 1995 would have been $266.6 million and
$229.8 million, respectively. Improved results for 1996 reflect colder
weather, cost control efforts and the full year impact of general rate
increases that went into effect in the latter part of 1995 at Peoples Natural
Gas, Hope Gas, Inc. (Hope Gas) and East Ohio Gas. Overall, weather in the
Company's retail service areas was 5.5 percent colder than 1995 and 5.6
percent colder than normal.

Excluding workforce reduction charges, operating income before income taxes
for the gas distribution operations in 1995 was up $70.8 million from 1994. In
addition to the general rate increases placed into effect in late 1994 and in
1995 at four distribution subsidiaries, colder weather, the addition of new
customers, higher transport volumes and lower wage and benefit costs in the
latter part of the year due to the workforce reduction programs contributed
favorably to 1995 results. Overall, weather in the Company's retail service
territories was 2.2 percent colder than 1994 and .5 percent colder than
normal.

Operating income before income taxes for the gas distribution operations
declined $7.9 million in 1994 due principally to warmer weather and higher
costs of operations. Overall, weather in the Company's retail service area was
3 percent warmer than 1993 and 4 percent warmer than normal. Two subsidiaries
were granted rate increases and another began collecting higher rates, subject
to refund. However, the increases were placed into effect in the latter part
of the year and did not have a significant impact on 1994 results.
 
  OPERATING REVENUES
Operating revenues of the gas distribution operations increased $160.3 million
in 1996 compared to 1995, to $1,905.5 million. Gas sales revenues were up
$152.3 million reflecting both higher average sales prices and higher sales
volumes. Average sales prices increased due to the impact of both higher unit
purchased gas costs passed through to customers and higher rates in place for
most of the Company's distribution customers. Colder weather was a major
factor in the increased sales volumes. Gas transportation and storage revenues
increased $10.1 million resulting from both higher volumes and rates.

Revenues of the gas distribution operations in 1995 declined $60.4 million
from the prior year. Gas sales revenues declined $81.0 million as lower
average sales prices more than offset the impact of higher sales volumes. The
lower average sales prices were the result of lower unit purchased gas costs
reflected in the rates charged to customers. Rate increases in late 1994 and
in 1995, however, helped hold down the decline in sales revenues. Gas
transportation and storage revenues increased $20.4 million in 1995 due to
both increased volumes and rates.
 
  DISTRIBUTION THROUGHPUT
Since distribution sales largely represent retail sales for space heating,
changes in sales volumes from one period to another are primarily a function
of the weather. In addition to sales service, the distribution operations
provide gas transportation services to a wide range of customers, primarily
commercial and industrial end users. Therefore, the volume of gas transported
can be affected by changes in both economic and market conditions.

</TABLE>
Colder weather and the net addition of approximately 17,000 residential and
commercial customers during 1996 contributed to the 1 percent increase in gas
sales volumes compared to the prior year. Residential gas sales volumes
increased 6.2 Bcf, to 218.7 Bcf, in 1996. Commercial sales decreased 3.0 Bcf
while volumes transported to these customers were up 7.2 Bcf. Deliveries to
industrial customers

were higher in 1996, increasing .6 Bcf to 138.8 Bcf. Sales to industrial
customers declined .4 Bcf to 6.9 Bcf, while transportation volumes increased
1.0 Bcf to 131.9 Bcf. Transportation to off-system customers increased 1.2 Bcf
in 1996.

Gas sales volumes were up 2 percent in 1995, reflecting colder weather and the
net addition of about 24,800 residential and commercial customers. Residential
and commercial gas sales increased 6.6 Bcf and .4 Bcf, respectively, compared
to 1994. While industrial sales volumes declined 2.1 Bcf, transportation
volumes to those customers increased 9.8 Bcf. Gas transported for commercial
customers was 29.8 Bcf in 1995, up 5.4 Bcf compared to 1994. Transportation to
off-system customers declined 1.5 Bcf in 1995.
 
TRANSMISSION
"Transmission" includes the results of the gas transmission, storage, by-
product and certain other activities of CNG Transmission and, prior to April
1, 1995, the activities of CNG Storage Service Company (CNG Storage). CNG
Storage was formed primarily to engage in the sale, lease or brokerage of gas
storage capacity obtained from third parties including the sale or lease of
base gas. The results of CNG Storage were not significant to the transmission
operations. Gas and oil production activities of CNG Transmission are included
in exploration and production operations.

Changing regulatory policies intended to increase competition in the natural
gas industry have been the principal factor affecting transmission operations
over the past several years. With the implementation of Order 636 effective
October 1, 1993, CNG Transmission abandoned its traditional sales service
which consisted of various elements of gas sales, transportation and storage
that were offered and priced as a single bundled service. Customers now have
even greater access to the Company's pipeline and storage capacity, together
with a range of options available with respect to gas transportation and
storage services.
 
  OPERATING INCOME BEFORE INCOME TAXES
Excluding workforce reduction charges of $5.1 million in 1996 and $6.0 million
in 1995, operating income before income taxes for the gas transmission
operations for 1996 and 1995 would have been $183.9 million and $156.4
million, respectively. Cost control efforts and increased gas transportation
and by-products revenues contributed to improved results in 1996.

Excluding workforce reduction charges, operating income before income taxes of
the gas transmission operations increased $10.1 million in 1995 compared to
1994. Higher rates resulting from CNG Transmission's general rate filing which
became effective July 1, 1994, and cost controls were the major factors for
the improved results in 1995.

Operating income before income taxes increased $2.9 million in 1994 and
reflected the first full year of applying the straight fixed variable rate
design under which operating income is less influenced by changes in
throughput than in the past. Significant factors affecting 1994 operating
results included increased transportation and storage service revenues,
competition from other pipelines, and higher operating costs not yet reflected
in rates.
 
  OPERATING REVENUES
Total operating revenues of the gas transmission operations were $32.4 million
higher in 1996 compared to 1995. Gas transportation and storage revenues
increased $9.7 million due to higher gas transportation revenues, which
increased $14.9 million due to higher volumes and rates. This increase was
partly offset by decreased storage service revenues. Revenues from the sale of
by-products increased $9.7 million due chiefly to higher sales rates.

Total operating revenues of the gas transmission operations increased $11.7
million in 1995 to $471.0 million. Gas transportation and storage revenues
increased $27.4 million in 1995 due primarily to higher transportation
revenues, which increased $24.3 million as higher rates more than offset
slightly lower transport volumes. Revenues from the sale of by-products
declined $10.2 million, due to the overall decline in volumes of products
sold.

  TRANSMISSION THROUGHPUT
The changing regulatory environment has created a number of opportunities for
pipeline companies to expand and serve new markets. The Company has taken
advantage of selected market expansion opportunities, concentrating its
efforts primarily in the Northeast and along the East Coast. This expansion
takes advantage of the Company's network of underground storage facilities and
the location and nature of its gridlike pipeline system as a link between the
country's major longline gas pipelines and the increasing energy demands of
East Coast markets. The Company's pipelines are part of an interconnected gas
transmission system which will enable retail end users to take advantage of
the accessibility of supplies nationwide in the evolving deregulation of the
gas industry at the retail level (see "Distribution," page 5, and "Gas and
Electric Industry Developments," page 11). In addition, such a network allows
the Company to manage its gas supply requirements in an efficient and flexible
manner.

Variations in weather conditions can also have a significant impact on the
throughput of the transmission operations, since a substantial portion of the
gas deliveries of these operations is ultimately used by space-heating
customers. Also, transmission operations provide transportation services to a
wide range of customers, including commercial and industrial end users,
electric power generators, and local utility companies. Therefore, the volume
of gas transported can also be affected by changes in economic and market
conditions. However, operating income for the transmission operations is not
significantly influenced by changes in throughput due to the straight fixed
variable rate design.

Total throughput for the gas transmission operations, consisting entirely of
transportation volumes and including intercompany activity, was 758.4 Bcf,
744.0 Bcf, and 748.4 Bcf for the years 1996, 1995 and 1994, respectively.
Throughput during the first quarter of 1996 was up 12 percent compared to the
prior year quarter due in part to colder weather while throughput for the
remainder of the year was lower than in 1995. First quarter 1995 throughput
was lower than the prior year period due to warmer weather, while throughput
was up for the balance of 1995 compared to 1994.
 
EXPLORATION AND PRODUCTION
"Exploration and production" includes the results of CNG Producing and the gas
and oil production activities of CNG Transmission.
 
  OPERATING INCOME BEFORE INCOME TAXES
Operating income before income taxes for the exploration and production
operations in 1996 was $133.2 million, compared with an operating loss before
income taxes of $200.5 million in 1995. However, the 1996 results include
workforce reduction charges of $.6 million while the 1995 results reflect a
non-cash charge of $226.2 million for the impairment of gas and oil producing
properties and workforce reduction charges totaling $7.7 million. Excluding
these special items, operating income before income taxes would have been
$133.8 million and $33.4 million for 1996 and 1995, respectively. The effects
of higher gas and oil wellhead prices and higher gas and oil production
contributed to the significantly improved operating results in 1996. Higher
prices and production also resulted in increased royalty expense and higher
production-related costs compared to the prior year. The Company added 272 Bcf
of gas equivalent from additions, revisions, and purchases of gas and oil
reserves in 1996.

Excluding special items, operating results for 1995 would have been slightly
lower than operating income before income taxes of $34.0 million in 1994. The
impact of continued low gas wellhead prices and lower gas and oil production
slightly offset the favorable impact of higher oil wellhead prices, a $7.5
million reduction in production-related expenses, and reductions in overhead
costs in 1995. In addition, depreciation and amortization expense was $32.1
million lower in 1995 resulting from the impairment of gas and oil producing
properties, the effect of gas and oil reserve additions, and lower production.
Reserves equivalent to 210 Bcf of gas were added in 1995.

Exploration and production operating income before income taxes in 1994
decreased $13.3 million. The effect of the decline in total operating revenues
due to lower prices and production was partially offset by decreases in
royalty expense and depreciation and amortization of $9.4 million and $21.2
million, respectively. The lower level of royalty expense is attributable
primarily to reduced gas and oil production during 1994. Lower production,
together with the recognition of additional proved gas and
 
                                       8
<PAGE>
 
oil reserves in the Gulf of Mexico, resulted in lower depreciation and
amortization expense for 1994. Reserves equivalent to 190 Bcf of gas at Viosca
Knoll 826, a deep-water project in the Gulf of Mexico in which the Company
holds a 50 percent interest, were added in 1994 and represent the largest
single addition of reserves in the Company's history.

*Cost-of-service. East Ohio Gas sold all of its remaining gas and oil reserves
during 1995. Hope Gas sold all of its remaining gas reserves to CNG Producing
during 1996. At December 31, 1996, the Company's remaining cost-of-service gas
reserves were held by Peoples Natural Gas.
- --------------------------------------------------------------------------------
The Company's average gas wellhead price in 1996 was $2.46 per Mcf, up $.57
from $1.89 in 1995. Gas production in 1996 was 147.5 Bcf, up 38 percent from
1995. The increase in gas production during 1996 was due partially to the
impact of two significant Gulf of Mexico projects which commenced production
in the 1996 first quarter, Popeye and Main Pass 225. Production also benefited
from the effect of production enhancement efforts at existing Company-operated
fields. Average oil wellhead prices were $17.60 per barrel in 1996, up $1.56
from 1995, while oil production increased 51 percent from the prior year. The
increase in oil production in 1996 was due in large part to production from
the Popeye project.

Consistent with prices nationwide, the Company's gas wellhead prices in 1995
were below prior year levels for most of the period as the average gas price
of $1.89 per Mcf was $.27 less than the 1994 price. As a result of continued
weak gas prices, the Company voluntarily shut in a portion of its production
at various times during 1995 which, in addition to normal declines at certain
properties, resulted in a decline in production compared to 1994. While
average oil wellhead prices rose $1.59 per barrel in 1995, oil production was
lower than 1994 due primarily to normal production declines at older
properties.
 
  OPERATING REVENUES
Total operating revenues for the exploration and production operations
increased 75 percent in 1996, to $632.3 million. Of the $159.3 million
increase in gas sales revenues in 1996, $90.8 million was due to higher
average gas prices and $68.5 million reflected increased volumes. Revenues
from oil and condensate production and brokering increased $108.9 million in
1996, with $77.7 million of the increase attributable to increased volumes and
the remaining increase due to higher rates. Revenues from oil brokering
increased $74.6 million while revenues from the sale of oil and condensate
production increased $34.3 million.

<PAGE>
 
Total operating revenues decreased $127.9 million in 1995, to $361.5 million.
Gas sales revenues declined $134.0 million, reflecting the continued low level
of gas wellhead prices and lower production compared to 1994. Revenues from
oil and condensate production and brokering increased $10.5 million in 1995.
Revenues from oil brokering were up $8.8 million due to both higher volumes
sold and higher rates, while revenues from oil and condensate production were
up $1.7 million as higher rates more than offset the effect of lower volumes.
 
ENERGY MARKETING SERVICES
"Energy marketing services" represents the results of CNG Energy Services
Corporation (CNG Energy Services) and CNG Power Services Corporation (CNG
Power Services). These subsidiaries, which are under a single management team,
were reported as one business component beginning in 1995. The results for
these subsidiaries were included in the "Other" component in 1994.

CNG Energy Services markets Company-owned gas production and arranges gas
supplies, transportation, storage and related services for customers. CNG
Energy Services also holds the Company's ownership interests in seven
independent power plants. CNG Power Services purchases and resells electricity
at market-based rates.

The energy marketing services component reported an operating loss before
income taxes of $9.1 million in 1996 compared to an operating loss before
income taxes of $5.7 million in 1995. The 1996 and 1995 results include
workforce reduction charges totaling $.3 million and $.5 million,
respectively. In addition to higher overhead costs, the 1996 loss occurred in
part because this component contracted for quantities of natural gas to supply
power plants during the summer air-conditioning season; these quantities
proved to be too high when third quarter 1996 weather turned cooler than
expected. Reduced transaction volumes during 1996 also adversely impacted 1996
operating results. Total throughput for this component was 427.1 Bcf in 1996
as compared to 570.8 Bcf in 1995. Power marketing, which includes the sale of
wholesale electricity, increased to 4,958,000 megawatt-hours in 1996 compared
to 1,948,000 megawatt-hours in 1995.

In addition to depressed gas margins throughout the year, 1995 operating
results also reflected a $5.3 million pretax charge recognized by CNG Energy
Services in December 1995 in connection with a mark-to-market valuation of
exchange-traded futures contracts used to manage price risk exposure related
to its stored gas inventories.

Income recognized in connection with CNG Energy Service's investments in 1996
and 1995 totaled $5.8 million and $3.9 million, respectively. These amounts
are not included in operating income or loss before income taxes but are
reflected in "Other income" for the component.
 
LIMITATION ON CAPITALIZED COSTS
As indicated in Note 1 to the consolidated financial statements, CNG Producing
and CNG Transmission follow the full cost method of accounting for their gas
and oil producing activities prescribed by the Securities and Exchange
Commission (SEC). Reference is made to Note 3 to the consolidated financial
statements, page 27, regarding the Company's recognition under the SEC full
cost rules of an impairment of its gas and oil producing properties at March
31, 1995. No additional impairment of these properties was required during the
remainder of 1995 or during 1996.

There are a number of factors, including prices, that determine whether or not
an impairment is required. Gas wellhead prices were strong during the fourth
quarter of 1996, and continued to be firm in the early part of 1997. However,
since gas wellhead prices are subject to sudden fluctuations, the impairment
of these gas and oil properties is a possibility at any quarterly measurement
date, unless other factors such as lower production costs or proved reserve
additions mitigate the impact of the price decline.
 
INTERNATIONAL ACTIVITIES
In January 1996, the Company formed a new subsidiary, CNG International
Corporation (CNG International). The purpose of CNG International is to engage
in energy-related activities outside the United States.
 
                                      10
<PAGE>
 
In December 1996, CNG International and El Paso Energy Corporation (El Paso)
entered into a joint venture to own and operate the Australian pipeline assets
formerly held by Tenneco Energy. CNG International and El Paso each own 30
percent of Epic Energy Pty Ltd. (Epic Energy), an Australian entity formed to
hold the investment's operating assets. The remaining 40 percent ownership
interest in Epic Energy is held equally among four Australian investors--
Allgas Energy, AMP Investments, Axion Funds Management and Hastings Funds
Management. The primary operating assets of the venture include two major
long-distance natural gas pipelines from Australia's Cooper Basin. One of the
pipelines carries gas from the city of Moomba south to Adelaide, while the
other was recently built and will carry gas from the city of Ballera east to
Wallumbilla, Queensland. CNG International's net investment in Epic Energy
totaled $38.7 million at December 31, 1996 and will be accounted for under the
equity method.

A marketing alliance formed in late 1994 among CNG Energy Services and two
Canadian firms, Hydro-Quebec and Noverco, was terminated in December 1996. The
informal alliance created by the three companies did not evolve into a formal
partnership due principally to regulatory impediments.
 
FEDERAL AND STATE REGULATORY MATTERS
 
  GAS AND ELECTRIC INDUSTRY DEVELOPMENTS
In the post-Order 636 gas industry environment, competition at the retail
level is receiving increased attention by state regulators. Several states
have commenced proceedings to evaluate restructuring of the natural gas
industry at the retail level. These proceedings have generally focused on
unbundling, incentive ratemaking, market-based rates and customer choice (see
"Distribution," page 5).

In addition to the further deregulation of the gas industry, the emerging
unbundling of services provided by electric utilities may ultimately result in
the convergence of both industries to create one overall, highly competitive
marketplace for a customer's total energy needs. During 1995 and 1996,
regulators at the federal and state levels finalized initiatives to promote
increased competition in the electric industry. These initiatives included
issuance in April 1996 of FERC Order Nos. 888 and 889 (Orders 888 and 889). By
requiring open access to the national electric transmission grid, Order 888
fosters increased competition in both the generation of electricity and the
supply of bulk power to major wholesale customers. A companion order, Order
889, addresses the timing, information access and other administrative details
associated with the FERC deregulation initiative. Other signs of an
increasingly deregulated electric utility environment include retail
competition plans adopted in several states, pilot retail wheeling programs
and pro-competition legislation proposed at both the federal and state levels.

Reflecting the evolution to a more competitive energy environment, the pace
and size of business combinations among natural gas and electric utilities
increased significantly during 1996. These business combinations have
generally been initiated to provide benefits from economies of scale, to
reduce costs by the elimination of duplicate facilities and processes, and to
improve the strategic and competitive position of the surviving entity. Recent
and pending regulatory actions may serve to further facilitate more business
combinations in the energy industry. The FERC has streamlined its regulatory
review process regarding pending mergers. In addition, the SEC has recommended
legislation to conditionally repeal the Public Utility Holding Company Act of
1935 (PUHCA), to which the Company is subject, in conjunction with legislation
which would grant the various state regulatory commissions greater oversight
authority of companies currently subject to the PUHCA. If legislation to
repeal or significantly modify the provisions of the PUHCA becomes law,
certain restrictions related to diversification activities, including business
combinations, for gas and electric companies subject to the PUHCA may be
eased.

Through its actions in recent years, the Company believes it is well-
positioned to compete in an evolving and increasingly deregulated energy
marketplace. The creation in 1997 of CNG Retail Services Corporation and the
ongoing development of the energy marketing services component, in conjunction
with streamlining and restructuring of its existing distribution, transmission
and exploration and production operations, reflects the Company's proactive
approach to meeting the demands of a more competitive and dynamic business
environment.

  FERC ORDER 636
With FERC approval, CNG Transmission implemented Order 636 effective October
1, 1993, in accordance with the terms of a comprehensive stipulation and
agreement (Settlement) reached with customers and others. Accordingly, from
late 1993 through 1996 CNG Transmission direct billed transition costs to
customers and affiliates totaling $178.6 million, net of refunds. Amounts
remaining to be collected at December 31, 1996 in connection with these direct
billings are not significant.

The Settlement also allows CNG Transmission to file with the FERC for rate
increases to recover both stranded and new facilities costs related to the
implementation of Order 636. The recovery of $5.0 million of stranded costs
was included in the settlement agreement approved by the FERC November 29,
1995 regarding its December 1993 general rate filing. Certain additional
stranded costs have been deferred in accordance with the Settlement pending
CNG Transmission's general rate filing in 1997. Through 1996, CNG Transmission
has incurred $8.0 million of new facilities costs related to Order 636, and
expects to incur up to $22.0 million in additional costs for such facilities.

Based on management's current estimates, the operating environment under Order
636 and any uncertainties pertaining to the recovery of remaining transition
costs should not have a material adverse effect on the Company's financial
position, results of operations or cash flows. Reference is made to Note 2 to
the consolidated financial statements for additional information regarding
Order 636 transition costs.
 
  STATE REGULATORY ISSUES
On September 25, 1996, Virginia Natural Gas filed an expedited rate
application with the Virginia State Corporation Commission requesting an
annual revenue increase of $13.9 million. The requested rate increase reflects
the recovery of higher operating costs and additional investment in facilities
required to serve customers on Virginia Natural Gas' system. The new rates
went into effect, subject to refund, on October 25, 1996.

On December 19, 1996, the PUCO approved the Company's merger of West Ohio Gas
into East Ohio Gas effective January 1, 1997. The merger is part of an overall
objective to improve the cost-effectiveness of the distribution operations and
to better position the Company for competing in the future energy environment.
 
ENVIRONMENTAL MATTERS
The Company is subject to various federal, state and local laws and
regulations relating to the protection of the environment. These laws and
regulations govern both current and future operations and potentially extend
to plant sites formerly owned or operated by the subsidiaries, or their
predecessors.

Reference is made to Note 16 to the consolidated financial statements, page
41, for a detailed description of environmental matters.

Estimates of liability in the environmental area are based on current
environmental laws and regulations and existing technology. The exact nature
of environmental issues which the Company may encounter in the future cannot
be predicted. Additional environmental liabilities may result in the future as
more stringent environmental laws and regulations are implemented and as the
Company obtains more specific information about its existing sites and
production facilities. At present, no estimate of any such additional
liability, or range of liability amounts, can be made. However, the amount of
any such liabilities could be material.
 
EFFECTS OF INFLATION
Although inflation rates have been moderate in recent years, any change in
price levels has an effect on operating results due to the capital intensive
and regulated nature of the Company's major business components. The Company
attempts to minimize the effects of inflation through cost control,
productivity improvements and regulatory actions where appropriate.

FINANCIAL CONDITION
 
DIVIDEND AND COMMON STOCK MATTERS
In December 1996, the Board of Directors continued the quarterly dividend on
the common stock at 48.5 cents a share. Total dividends paid to common
shareholders in 1996 were $183.0 million compared with $180.8 million in 1995
and $180.4 million in 1994.

During 1996, a total of 1,372,716 original issue shares were issued through
various Company-sponsored plans, including 768,531 shares acquired by
employees through the exercise of outstanding stock options.

Under the Company's stock repurchase plan, up to 4 million shares of the
outstanding common stock can be repurchased. The shares may be purchased in
the open market from time-to-time, depending on market conditions. The Company
may also acquire shares of its common stock through certain provisions of the
various stock incentive plans. The shares repurchased or acquired are held as
treasury stock and are available for reissuance for general corporate purposes
or in connection with various employee benefit plans. No treasury shares were
held by the Company at December 31, 1995. During 1996, no open market
purchases were made by the Company. The Company acquired 146,667 shares in
1996 through the provisions of its employee incentive plans at a cost of
$8,144,000, or an average price of $55.53 a share. All of these shares were
sold before year-end to the Company's benefit plans.
 
CAPITAL SPENDING
The current capital spending program for 1997 is estimated at $525.9 million,
a 6.1 percent decrease compared with total capital spending in 1996. The
estimated 1997 budget has been allocated as follows: distribution, $150.3
million; transmission, $82.7 million; exploration and production, $231.4
million; energy marketing services, $5.6 million; and corporate and other,
$55.9 million. The decreased level of capital expenditures anticipated for
1997 assumes slightly lower spending for exploration and production
operations, reflecting reduced spending on deep-water projects and increased
conventional drilling, both onshore and offshore. Transmission and
distribution operations expenditures will primarily be limited to spending for
enhancements and improvements in the pipeline system and related facilities.
The "corporate and other" category includes expenditures to upgrade
information systems technology, primarily to centralize and consolidate
services and financial systems, and to invest in selected international
projects.

Funds required for the capital spending program, as well as for other general
corporate purposes, are expected to be obtained principally from internal cash
generation. Although the Company does not expect to require long-term
financing in 1997 to support capital spending, it may turn to the market to
take advantage of other opportunities and to increase its financial
flexibility.
 
CAPITAL RESOURCES AND LIQUIDITY
Because of the seasonal nature of the regulated subsidiaries' heating
business, a substantial portion of the Company's cash receipts are realized in
the first half of the year. However, cash requirements for capital
expenditures, dividends, debt retirements and other working capital needs do
not track this pattern of cash receipts. Consequently, additional cash needs
are satisfied through the sale of short-term commercial paper notes or by the
issuance of long-term debt. As shown in the Consolidated Statement of Cash
Flows, net cash provided by operating activities was $407.2 million, $552.7
million and $631.3 million for the years 1996, 1995 and 1994, respectively.
The decline in net cash provided by operating activities in 1996 was due in
part to the deferral of purchased gas costs in excess of costs currently
recovered in rates and the payment of customer refunds during the period.
Lower gas wellhead prices and rate-related refunds made to customers were the
principal reasons for the lower cash flows from operations in 1995.

During October 1996, the Company sold $150 million of 6 7/8% Debentures Due
October 15, 2026. The Debentures are noncallable but will be redeemed at par
at the option of the holder on October 15, 2006. In December 1996, the Company
sold $150 million of 6 5/8% Debentures Due December 1, 2008. The net proceeds
from these sales were, and will be, used to finance, in part, 1996 and 1997
capital expenditures and to reduce short- and/or long-term debt.
 
                                      13

During December 1996, the Company called for redemption $53.125 million
principal amount of the 8 5/8% Debentures Due December 1, 2011. In connection
with the call, the Company placed funds into an irrevocable trust in December
1996 for the sole purpose of paying the principal amount and related call
premium and accrued interest. As such, the debt was removed from the
Consolidated Balance Sheet at December 31, 1996. Payment was made from the
trust on February 1, 1997. This transaction resulted in a charge amounting to
$5.0 million in 1996.

The Company has shelf registrations with the SEC for the sale of up to $50
million of debt securities. In addition, the Company anticipates filing a new
shelf registration during 1997 which would allow it to sell up to an
additional $950 million of debt and/or equity securities. The amount and
timing of any future sale of these securities will depend on capital
requirements, including financing necessary to enable the Company to pursue
asset acquisition opportunities, and financial market conditions.

The Company's embedded long-term debt cost, excluding current maturities, at
year-end 1996 was 7.27 percent, compared with 7.69 percent for 1995 and 7.74
percent for 1994. The long-term debt to capitalization ratio was 39.3 percent
at the end of 1996, and 38.7 percent and 34.5 percent at year-end 1995 and
1994, respectively. Under the provisions of one of the indentures covering the
Company's outstanding senior debenture issues, the ratio cannot exceed 60
percent. The Company's senior debentures are rated A1 by Moody's Investors
Service, AA- by Standard & Poor's, AA- by Duff and Phelps, and AA by Fitch
Investors Service.

At December 31, 1996, the Company had two short-term credit agreements with a
group of banks, for $475 million and $300 million. The Company made no
borrowings under these agreements during 1996 and there were no amounts
outstanding under any credit agreements at December 31, 1996 or 1995.

The Company utilizes short-term borrowings to finance gas inventories and
other working capital requirements. Funds from the sale of commercial paper
notes were used for these purposes in 1996, of which $374 million was
outstanding at year-end. The Company may utilize unused portions of its credit
agreements to provide support for commercial paper notes.

In the normal course of business, certain of the nonregulated subsidiaries
utilize derivatives to manage exposure to price risk in connection with the
production, purchase and sale of natural gas and oil, purchase and sale of
electricity, and for stored gas inventories. The use of derivatives exposes
the Company to market risk and credit risk. Market risk represents the
potential loss that can be caused by a change in the market value of a
particular commitment. Although the use of derivatives generally reduces
market risk exposure due to unfavorable price fluctuations, risk management
activities, while not significant, can result in the assumption of a limited
degree of price risk in certain isolated transactions. Credit risk relates to
the risk of loss that the Company would incur as a result of nonperformance by
counterparties pursuant to the terms of their contractual obligations. The
Company does not have a significant exposure to any individual counterparty to
its energy price risk management activities. Management has operating
procedures in place to evaluate market and credit risks and believes that the
Company's exposure to risks associated with derivatives is not material in
relation to the Company's financial position, results of operations or cash
flows. Reference is made to Notes 1 and 15 to the consolidated financial
statements, pages 23 and 39, regarding energy price risk management
activities.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
Consolidated Natural Gas Company
 
In our opinion, the consolidated financial statements appearing on pages 19
through 50 of this Appendix I to the proxy statement for the 1997 annual meeting
of stockholders present fairly, in all material respects, the financial position
of Consolidated Natural Gas Company and subsidiaries (the Company) at December
31, 1996 and 1995, and the results of their operations and their cash flows for
each of the three years in the period ended December 31, 1996, in conformity
with generally accepted accounting principles. These financial statements are
the responsibility of the Company's management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

CONSOLIDATED NATURAL GAS COMPANY AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Methods of allocating costs to accounting periods by the subsidiary companies
subject to federal or state accounting and rate regulation may differ from
methods generally applied by nonregulated companies. However, when the
accounting allocations prescribed by regulatory authorities are used for
ratemaking, the economic effects thereof determine the application of
generally accepted accounting principles. Significant accounting policies of
Consolidated Natural Gas Company (the Parent Company) and subsidiaries (the
Company) within this framework are summarized in this Note.
 
USE OF ESTIMATES
The consolidated financial statements reflect certain estimates and
assumptions made by management that affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities at the date
of the financial statements, and the reported amounts of revenues and expenses
for the periods presented.
 
PRINCIPLES OF CONSOLIDATION
The Parent Company owns all of the capital stock of its subsidiaries. The
consolidated financial statements represent the accounts of the Company after
the elimination of intercompany transactions.

The Company follows the equity method of accounting for investments in
partnerships and corporate joint ventures when the Company is able to
influence the financial and operating policies of the investee. For all other
investments, the cost method is applied.
 
REVENUE RECOGNITION
Revenues from gas sales and transportation services are recognized in the same
period in which the related gas volumes are delivered to customers. The
Company bills and recognizes sales revenues from residential and certain
commercial and industrial customers on the basis of scheduled meter readings.
In addition, revenues are recorded for estimated deliveries of gas to these
customers from the meter reading date to the end of the accounting period. For
wholesale and other commercial and industrial customers, revenues are based
upon actual deliveries of gas to the end of the period.
 
UNRECOVERED GAS COSTS
Where permitted by regulatory authorities, the Company defers the difference
between the cost of gas (including certain related costs) and the amount of
such costs included in current rates. The differences are accounted for as
either unrecovered gas costs or amounts payable to customers. Unrecovered
amounts are recognized as purchased gas costs in future periods when the costs
are recovered through adjusted rates.
 
ENERGY PRICE RISK MANAGEMENT ACTIVITIES
In the normal course of business, certain of the nonregulated subsidiaries
utilize commodity futures and option contracts and derivative financial
instruments to manage exposure to price risk in connection with the
production, purchase and sale of natural gas and oil, purchase and sale of
electricity, and for stored gas inventories. Derivative financial instruments
may also be used from time to time to manage foreign currency risk in
connection with certain contractual commitments. Exchange-traded instruments
which permit settlement by physical delivery of the commodity under contract
are not considered derivative financial instruments under SFAS No. 119,
"Disclosure about Derivative Financial Instruments and Fair Value of Financial
Instruments." The derivative financial instruments utilized by the
subsidiaries include over-the-counter (OTC) commodity price swap agreements,
OTC foreign currency swap agreements and OTC options which require settlement
in cash. Under the price swap agreements, the subsidiaries make payments to,
or receive payments from, counterparties generally based on the difference
between fixed
 
                                      23

CONSOLIDATED NATURAL GAS COMPANY AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

and variable gas and oil prices or on prices at different receipt points as
specified in the contracts. Under foreign currency swap agreements, payments
are made to, or received from, counterparties generally based on the
difference in the current foreign exchange rate. Settlement takes place under
the swap agreements on a monthly basis, and amounts received or paid are
recognized as an adjustment to gas and oil sales revenues, purchased gas
expense or transport capacity costs in that month to correspond with the
recognition of the related physical transaction.

For derivative financial instruments or exchange-traded contracts that qualify
(based on correlation to price movements of gas and oil) and are designated as
hedges, related gains or losses are deferred and subsequently recognized in
income, as revenues or expense, in the same period the hedged transaction
occurs. The value of derivatives that do not qualify for hedge accounting
treatment are marked-to-market each period, with gains and losses recognized
in the operating income of that period.

Margin accounts for open futures contracts are recorded in the Consolidated
Balance Sheet under "Prepayments and other current assets." Deferred losses or
gains are reflected in the Consolidated Balance Sheet under "Deferred charges
and other assets" and "Deferred credits and other liabilities," respectively.
Cash flows from price risk management activities are reported in the
Consolidated Statement of Cash Flows as an operating activity--consistent with
the category of the cash flows from the underlying physical transaction.
 
PROPERTY, PLANT AND EQUIPMENT AND DEPRECIATION
 
  GAS UTILITY AND OTHER PLANT
The property, plant and equipment accounts are stated at the cost incurred or,
where required by regulatory authorities, "original cost." Additions and
betterments are charged to the property accounts at cost. Upon normal
retirement of a plant asset, its cost is charged to accumulated depreciation
together with costs of removal less salvage. The costs of maintenance, repairs
and replacing minor items are charged principally to expense as incurred.
 
  EXPLORATION AND PRODUCTION PROPERTIES
CNG Producing and CNG Transmission follow the full cost method of accounting
for gas and oil producing activities prescribed by the SEC. Under the full
cost method, all costs directly associated with property acquisition,
exploration, and development activities are capitalized, with the principal
limitation that such amounts not exceed the present value of estimated future
net revenues to be derived from the production of proved gas and oil reserves.
If net capitalized costs exceed the estimated value at the end of any
quarterly period, then a permanent write-down of the assets must be recognized
in that period.

The gas producing activities of Peoples Natural Gas are subject to cost-of-
service rate regulation and are exempt from the accounting methods prescribed
by the SEC.
 
  DEPRECIATION AND AMORTIZATION
Depreciation and amortization are recorded over the estimated service lives of
plant assets by application of the straight-line method or, in the case of gas
and oil producing properties, the unit-of-production method.

Under the full cost method of accounting, amortization is also accrued on
estimated future costs to be incurred in developing proved gas and oil
reserves, and on estimated dismantlement and abandonment costs net of
projected salvage values. However, the costs of investments in unproved
properties and major development projects are excluded from amortization until
it is determined whether or not proved reserves are attributable to such
properties.
 
  ACCOUNTING FOR IMPAIRMENTS
Effective January 1, 1996, the Company adopted the provisions of SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
to Be Disposed Of." This standard requires
 
                                      24
<PAGE>
 
CONSOLIDATED NATURAL GAS COMPANY AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

that long-lived assets and certain intangibles be reviewed for impairment when
events or changes in circumstances indicate that the carrying amount of an
asset may not be recoverable. If the aggregate estimated future cash flows to
be derived from an asset are less than its carrying amount, an impairment must
be recognized. The Company's gas and oil producing activities that are subject
to the SEC's full cost accounting method will continue to be evaluated for
impairment under SEC Regulation S-X. SFAS No. 121 also requires the write-off
of a regulatory asset if and when it is no longer probable that future
revenues will provide for the recovery of the carrying value of the asset. The
adoption of SFAS No. 121 did not have a material effect on the Company's
financial position, results of operations or cash flows.
 
ALLOWANCE FOR FUNDS USED DURING CONSTRUCTION
The subsidiaries subject to cost-of-service rate regulation capitalize the
estimated costs of funds used during the construction of major projects. Under
regulatory practices, those companies are permitted to include the costs
capitalized in rate base for rate-making purposes when the completed
facilities are placed in service. The remaining subsidiaries capitalize
interest costs as part of the cost of acquiring certain assets. Generally,
interest is capitalized on unproved properties and major construction and
development projects on which amortization is not yet being recognized.
  In determining the allowance for funds used during construction, the
following ranges of rates reflect the pretax cost of borrowed funds used to
finance construction expenditures: 1994--3 3/8% to 8 1/4%; 1995--5 3/4% to 8
3/8% and 1996--5 1/2% to 8 1/8%. Equity funds capitalized in those years were
not significant.
 
INCOME TAXES
The current provision for income taxes represents amounts paid or currently
payable. Investment tax credits which were required to be deferred by
regulatory authorities are being amortized as credits to income over the
estimated service lives of the related properties.
 
PENSION AND OTHER BENEFIT PROGRAMS
 
  PENSION PROGRAM
The Company has qualified noncontributory defined benefit pension plans
covering substantially all employees. Benefits payable under the plans are
based primarily on each employee's years of service, age and base salary
during the five years prior to retirement. Net pension costs are determined by
an independent actuary, and the plans are funded on an annual basis to the
extent such funding is deductible under federal income tax regulations. Plan
assets consist primarily of equity securities, fixed income securities and
insurance contracts. The pension program also includes the payment of
supplemental pension benefits to certain retirees depending on retirement
dates, and the payment of benefits to certain retired executives under
company-sponsored nonqualified employee benefit plans. Certain of these
nonqualified benefit plans have been partially funded through contributions to
a grantor trust.
 
  OTHER POSTRETIREMENT BENEFITS
In addition to pension plans, the Company sponsors defined benefit
postretirement plans covering both salaried and hourly employees and certain
dependents. The plans provide medical benefits as well as life insurance
coverage. These benefits are provided through insurance companies and other
providers with the annual cash outlays based on the claim experience of the
related plans.

Employees who retire on or after attaining age 55 and having rendered at least
15 years of service, or employees retiring on or after attaining age 65, are
eligible to receive benefits under the plans. The plans are both contributory
and noncontributory, depending on age, retirement date, the plan elected by
the employee, and whether the employee is covered under a collective
bargaining agreement. Most of the medical plans contain cost-sharing features
such as deductibles and coinsurance. For certain of the contributory medical
plans, retiree contributions are adjusted annually.

ENVIRONMENTAL EXPENDITURES
Environmental-related expenditures associated with current operations are
generally expensed as incurred. Expenditures for the assessment and/or
remediation of environmental conditions related to past operations are charged
to expense or are deferred pending probable recovery in future rate-making
proceedings. In this connection, a liability is recognized when the assessment
or remediation effort is probable and the future costs are estimable.
Estimated future costs for the abandonment and restoration of gas and oil
properties are accrued currently through charges to depreciation.

Claims for recovery of environmental-related costs from insurance carriers and
other third parties or through regulatory procedures are recognized separately
as assets when future recovery is deemed probable.
 
EARNINGS PER SHARE
Earnings per share of common stock is computed based on the weighted average
number of common shares outstanding during the period. Under the methods
prescribed by generally accepted accounting principles, the assumed exercise
of outstanding stock options and conversion of the Company's outstanding
convertible subordinated debentures are not considered to have a dilutive
effect on earnings per share.
 
TEMPORARY CASH INVESTMENTS
Temporary cash investments consist of short-term, highly liquid investments
that are readily convertible to cash and present no significant interest rate
risk. For purposes of the Consolidated Statement of Cash Flows, temporary cash
investments are considered to be cash equivalents.
 
2. RATE MATTERS
 
The Company accounts for its regulated operations in accordance with SFAS No.
71, "Accounting for the Effects of Certain Types of Regulation." When the
accounting allocations prescribed by regulatory authorities are used for
ratemaking, the allocation of costs among accounting periods by the Company's
regulated subsidiaries resulted in the recognition of regulatory assets and
liabilities at December 31, 1995 and 1996 as follows:

CONSOLIDATED NATURAL GAS COMPANY AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The Company assesses on an ongoing basis the recoverability of costs
recognized as regulatory assets and its ability to continue to apply SFAS No.
71 to its regulated operations. In the event that all or a portion of the
Company's regulated operations ceased to meet the requirements of SFAS No. 71,
the Company would be required to assess the carrying value of certain assets
and liabilities previously subject to regulation.
 
ESTIMATED RATE CONTINGENCIES AND REFUNDS
Certain increases in prices by the Company and other rate-making issues are
subject to final modification in regulatory proceedings. The related
accumulated provisions pertaining to these matters were $24,239,000 and
$6,851,000 at December 31, 1995 and 1996, including interest. These amounts
are reported in the Consolidated Balance Sheet under "Estimated rate
contingencies and refunds" together with $35,124,000 and $14,751,000,
respectively, which are primarily refunds received from suppliers and
refundable to customers under regulatory procedures.
 
ORDER 636 TRANSITION COSTS
As approved by the FERC, CNG Transmission has billed its customers, including
certain affiliates, a total of $178.6 million, representing unrecovered
purchased gas costs and unrecovered sales-related transportation costs,
resulting from its transition to restructured services under Order 636. Of the
total amount billed by CNG Transmission to the distribution subsidiaries, the
portion remaining to be recovered from their customers at December 31, 1996 is
not material to the Company's financial position, results of operations or
cash flows.

The distribution subsidiaries have incurred or are expected to incur
additional obligations to upstream pipeline companies for transition costs
under Order 636. The total estimated liability for such costs was $37,021,000
and $27,727,000 at December 31, 1995 and 1996, respectively. Additional
amounts are likely to be accrued in the future once the pipeline companies
receive final FERC approval to recover these costs. Based on management's
current estimates, the distribution subsidiaries' portion of such costs is not
expected to be material.

Based on regulatory actions in two jurisdictions and the past rate-making
treatment of similar costs in the other jurisdictions, management believes
that the distribution subsidiaries should generally be able to pass through
all Order 636 transition costs to their customers.
 
3. PROPERTY, PLANT AND EQUIPMENT AND DEPRECIATION
 
IMPAIRMENT OF GAS AND OIL PRODUCING PROPERTIES
As described in Note 1, certain of the subsidiaries follow the full cost
method of accounting for gas and oil producing activities as prescribed by the
SEC. Under these rules, the Company recognized an impairment of its gas and
oil producing properties at March 31, 1995, due primarily to the decline in
gas wellhead prices. The non-cash charge amounted to $226,209,000 and reduced
1995 net income by $145,000,000, or $1.56 per share.
 
DEPRECIATION AND AMORTIZATION
Amortization of capitalized costs under the full cost method of accounting for
the Company's exploration and production operations amounted to $1.15 per Mcf
equivalent of gas and oil produced in 1994, $.98 in 1995, and $.93 in 1996.
The 1995 amount includes the effect of the write-down of the gas and oil
producing properties noted above.

There are no significant properties, as defined by the SEC, excluded from
amortization at December 31, 1996. As gas and oil reserves are proved through
drilling or as properties are judged to be impaired, excluded costs and any
related reserves are transferred on an ongoing, well-by-well basis into the
amortization calculation.
 
WRITE-DOWN AND SUBSEQUENT SALE OF COAL PROPERTIES
In early 1995, the Company initiated an evaluation of the possible disposition
of the coal reserves and related properties owned by CNG Coal Company (CNG
Coal). These reserves had been acquired in the late 1960s and 1970s to meet
expected long-term gas supply needs through coal gasification. However, due to
gas industry deregulation, excess gas supplies nationwide, and both low demand
and prices for coal, the Company concluded that it was not economically
feasible to develop such reserves, nor were these assets aligned with the
Company's longer-term strategy.

A property appraisal was completed during the second quarter of 1995 by an
independent geological firm, which indicated that a write-down was warranted.
Accordingly, at June 30, 1995, the cost of these properties was written down
resulting in a pretax charge amounting to $31,266,000. This charge reduced
1995 net income by $20,323,000, or 22 cents per share, but had no effect on
the Company's cash flow. In July 1996, CNG Coal completed the sale of its coal
properties to a subsidiary of Cyprus Amax Minerals Company. Sale proceeds
consist of an initial cash payment, cash to be received in the form of equal
annual installments, and payments to be received from the future production of
the coal reserves. The proceeds from the sale approximated the book value of
these properties.
 
4. WORKFORCE REDUCTION COSTS
 
Workforce reduction programs approved during 1995 by the Board of Directors
consisted of a voluntary early retirement program and an involuntary separation
program. The early retirement incentives included five additional years of age
and service for determining pension benefits. The early retirement program was
offered at six subsidiaries from April 1 through May 31, 1995, and at a seventh
subsidiary from July 1 through August 31, 1995. Eligible employees at each
subsidiary were required to retire before December 31, 1995. The involuntary
separation program involved severance benefit payments to affected employees.

In January 1996, unions at two subsidiaries approved the adoption of a workforce
reduction program that consisted of a voluntary early retirement program and a
voluntary separation program. The early retirement incentives were similar to
those offered at other subsidiaries during 1995. The early retirement program
was offered from February 1 through March 31, 1996, with eligible employees
retiring effective April 1, 1996. The voluntary separation program involved
severance benefit payments to affected employees. In September 1996, the Board
of Directors approved a separate voluntary early retirement program for West
Ohio Gas. The program included early retirement incentives similar to those

offered previously at other subsidiaries and was offered from October 1
through November 29, 1996, with eligible employees retiring effective December
1, 1996.

During 1995 and 1996, a total of 571 and 119 eligible employees, respectively,
elected to accept the early retirement offer and an additional 217 and 57,
respectively, were separated from the Company in conjunction with these
programs. In addition, during the fourth quarter of 1996 the Company recorded
a provision for severance and related benefits to be paid to affected
employees in connection with the Company's efforts to combine and streamline
certain business functions. As a result of these workforce reduction programs,
the Company recorded charges to "Operation expense" in the 1995 and 1996
Consolidated Statements of Income amounting to $42,555,000 and $15,195,000,
respectively. These charges reduced 1995 and 1996 net income by $25,618,000,
or 27 cents per share, and $9,855,000, or 10 cents per share, respectively.
The portion of the 1996 charges recognized in the fourth quarter amounted to
$11,816,000 and reduced net income for the quarter by $7,786,000, or 8 cents
per share. In addition, certain of the regulated subsidiaries have deferred,
as a regulatory asset, a portion of their workforce reduction costs pending
recovery in future rates. The balance of these deferrals was $11,139,000 at
December 31, 1996. The total workforce reduction costs include the impact of
curtailment accounting for the pension and postretirement benefit plans.
Details of the costs are shown in the following table.

In 1989, Peoples Natural Gas offered special retirement incentives to certain
salaried and hourly employees. The additional pension payments resulting from
these incentives are being paid from the assets of the applicable pension
plans. The estimated cost of these additional benefits, amounting to
approximately $8,000,000, was deferred and is being amortized to expense over
a 10-year period which began October 1, 1990, in accordance with the rate-

The projected benefit obligation at December 31, 1995 and 1996, was determined
using an annual discount rate of 7.0% and 7.5%, respectively, and an average
assumed annual rate of salary increase of 5.5%. The expected long-term rate of
return on plan assets was 8.0% per annum at December 31, 1995 and 9.0% at
December 31, 1996.

The Company applied the provisions of SFAS No. 87 to certain nonqualified
employee benefit plans effective July 1, 1995. The minimum liability
recognized relating to both the Company's nonqualified employee benefit and
supplemental pension plans was $17,909,000 and $13,612,000 at December 31,
1995 and 1996. The related intangible asset recognized as of those dates
amounted to $15,605,000 and $11,486,000, respectively. These amounts are
included in the Consolidated Balance Sheet under "Deferred credits and other
liabilities" and "Deferred charges and other assets." Adjustments of the
minimum liability and intangible asset due to changes in assumptions or the
financial status of the plans resulted in a charge to retained earnings of
$262,000 at December 31, 1995, and a credit to retained earnings of $116,000
at December 31, 1996.

</TABLE>
As permitted, the Company elected to amortize the accumulated postretirement
benefit obligation existing at January 1, 1993 (transition obligation) over a
20-year period. The weighted average discount rate used in determining the
accumulated postretirement benefit obligation at December 31, 1995 and 1996,
was 7.0% and 7.5%, respectively. The average assumed annual rate of salary
increase for the applicable life insurance plans was 5.0% for 1995 and 5.5%
for 1996.

The assumed health care cost trend rate used in measuring the accumulated
postretirement benefit obligation for the medical plans is 8.0% for 1997,
declining gradually to 5.0% in 2003 and remaining at that level thereafter.
The health care cost trend rate assumption has a significant effect on the
amounts reported. If the health care cost trend rate were increased by 1% in
each year, the accumulated postretirement benefit obligation as of December
31, 1996, would be increased by $36.4 million. A 1% change would also increase
the aggregate of the service and interest cost components of net periodic
postretirement benefit cost for 1996 by $5.4 million.

The majority of the estimated postretirement benefit costs and the transition
obligation is attributable to the rate-regulated subsidiaries. Pending the
expected recovery of SFAS No. 106 costs and related deferrals in regulatory
proceedings, these subsidiaries have deferred the differences between SFAS
No. 106 costs and amounts included in rates. In general, the rate-regulated
subsidiaries have obtained

approval for recovery in rates from their respective regulatory commissions
for the increased level of expense resulting from SFAS No. 106. The amount of
SFAS No. 106 costs deferred at December 31, 1995 and 1996, was $68,026,000 and
$58,966,000, respectively, which is included in the Consolidated Balance Sheet
under "Deferred charges and other assets."

The FERC and certain state regulatory authorities have indicated that when
SFAS No. 106 costs are recovered in rates, amounts collected must be deposited
in irrevocable trust funds dedicated for the sole purpose of paying
postretirement benefits. Accordingly, four subsidiaries fund postretirement
benefit costs via voluntary employees' beneficiary associations (VEBAs). The
remaining subsidiaries do not prefund postretirement benefit costs, but rather
pay claims as presented. Assets held by the VEBAs consist primarily of short-
term fixed income securities.

The current and noncurrent deferred income taxes reported in the Consolidated
Balance Sheet at December 31, 1996, represent the net expected future tax
consequences attributable to temporary differences between the carrying
amounts of nontax assets and liabilities and their tax bases. These temporary
differences and the related tax effect were as follows:

</TABLE>
A regulatory liability amounting to $57,867,000 has been recorded representing
the reduction to previously recorded deferred income taxes associated with
rate-regulated activities that are expected to be refundable to customers, net
of certain taxes collectible from customers. Also, a regulatory asset
corresponding to the recognition of additional deferred income taxes not
previously recorded because of past rate-making practices amounting to
$101,825,000 has been recorded at December 31, 1996. These amounts are
included in the Consolidated Balance Sheet under "Deferred credits and other
liabilities" and "Deferred charges and other assets," respectively.
 
8. GAS STORED
 
The distribution subsidiaries, except Virginia Natural Gas, value their stored
gas inventory under the LIFO method. Based upon the average price of gas
purchased during 1996, the current cost of replacing the inventory of "Gas
stored--current portion" exceeded the amount stated on a LIFO basis by
approximately $196,474,000 at December 31, 1996. Virginia Natural Gas and CNG
Energy Services value their stored gas inventory under the weighted average
cost method.

A portion of gas in underground storage used as a pressure base and for
operational balancing is included in "Property, Plant and Equipment" in the
amounts of $126,393,000 and $126,366,000 at December 31, 1995 and 1996,
respectively.
 
9. UNAMORTIZED ABANDONED FACILITIES
 
In 1988, Consolidated LNG received FERC approval for the abandonment of its
interest in liquefied natural gas facilities at Cove Point, Maryland. In
connection with the abandonment, Consolidated LNG recorded a deferred asset in
accordance with the provisions of SFAS No. 90, "Accounting for Abandonments
and Disallowances of Plant Costs." This deferred asset, which represents the
present value of allowable costs expected to be recovered, is being amortized
over the 10-year recovery period which began March 1, 1988, as prescribed in
the FERC order.

SHAREHOLDER RIGHTS PLAN
During 1995, the Board of Directors adopted a shareholder rights plan and on
January 23, 1996, declared a dividend of one right (Right) for each share of
common stock outstanding at the close of business on February 28, 1996. Each
Right would entitle the holder to purchase from the Company one-half of one
share of common stock at a price of $175 per share ($87.50 per half-share),
subject to adjustment (Purchase Price), if certain conditions are met in
connection with a possible acquisition of the common stock of the Company by a
third party. If the Rights become exercisable, each holder may exercise a
Right and receive common stock (or, in certain cases, cash, property or other
securities) of the Company or common stock of the acquiring company having a
value equal to twice the Right's then current Purchase Price.

Also, under certain conditions, the Board of Directors may exchange the
Rights, in whole or in part, at an exchange ratio of one share of common stock
(and/or other securities, cash or other assets having the same value as a
share of common stock) per Right, subject to adjustment, or may redeem the
Rights in whole at a price of $0.01 per Right. Until a Right is exercised or
exchanged for common stock, the holder, as such, is not a stockholder of the
Company. Unless earlier exercised or redeemed, the Rights will expire on
February 28, 2006.
 
UNISSUED SHARES
At December 31, 1996, 305,066,369 shares of common stock were unissued. Of
these, a total of 14,738,762 shares have been registered with the SEC for
possible issuance under various benefit plans. Shares acquired by these plans
can consist of original issue shares, treasury shares or shares purchased in
the open market. In addition, 2,001,512 shares have been registered with the
SEC for possible issuance to shareholders under the Dividend Reinvestment Plan
and 4,559,353 shares are registered for issuance upon conversion of the
Company's convertible subordinated debentures.
 
TREASURY STOCK
Under a stock repurchase plan approved by the Board of Directors, the Company
can purchase in the open market up to 4,000,000 shares of its common stock.
The Company may also acquire shares of its common stock through certain
provisions of the Company's various stock incentive plans. Shares repurchased
or acquired are held as treasury stock and are available for reissuance for
general corporate purposes or in connection with various employee benefit
plans. When treasury shares are reissued, the difference between the market
value at reissuance and the cost of shares is reflected in "Capital in excess
of par value." The cost of any shares held as treasury stock is shown as a
reduction in common stockholders' equity in the Consolidated Balance Sheet. No
treasury shares were held at December 31, 1995 or 1996.
 
1991 STOCK INCENTIVE PLAN
The 1991 Stock Incentive Plan (1991 Plan) provides for the granting of stock
awards, stock options and other stock-based awards to employees of the
Company. The maximum number of shares available for issuance in each calendar
year is determined in accordance with a formula contained in the plan. During
1996, 4,036,272 shares were available for issuance under the plan.

Stock awards granted under the plan may be in the form of restricted stock or
deferred stock. Shares issued as restricted stock awards are held by the
Company until the attached restrictions lapse. Deferred stock awards generally
consist of a right to receive shares at the end of specified deferral periods.
The market value of the stock award on the date granted is recorded as
compensation expense over the applicable restriction or deferral period.

Stock options granted under the plan allow the purchase of common shares at a
price not less than fair market value at the date of grant and not less than
par value. The options generally are exercisable in
 
                                      35

four equal annual installments commencing with the second anniversary of the
grant and expire after 10 years from the date of grant.

Stock appreciation rights may also be granted, either alone or in tandem with
stock options. These rights permit the recipient to receive, upon exercise,
the excess of the fair market value of a share on the date of exercise over
the grant price. The grant price is generally the fair market value of the
stock on the date of grant. As of December 31, 1996, no stock appreciation
rights have been granted under the plan.

The 1991 Plan also provides for the granting of performance awards, dividend
equivalents, or other awards which may be based on, or related to, shares of
the Company's common stock. The granting of stock awards constitutes a non-
cash financing activity of the Company.
 
1995 EMPLOYEE STOCK INCENTIVE PLAN
The 1995 Employee Stock Incentive Plan (1995 Plan) was established in
conjunction with the Long-Term Strategic Incentive Program described below.
This plan provides for the granting of stock-based awards to certain key
employees similar to those granted under the 1991 Plan. During 1996, 4,000,000
shares were available for issuance under the plan.
 
  LONG-TERM STRATEGIC INCENTIVE PROGRAM
In December 1995, the Board of Directors approved the Long-Term Strategic
Incentive Program. Grants under this program, consisting of performance
restricted stock awards (performance shares) and stock options, are expected
to be made every three years. Performance shares will vest contingent upon
attainment of certain strategic business results over a three-year period.
Stock options granted under this program vest after three years and will be
exercisable for one day. The exercise period can be extended from the vesting
date up to 10 years from the grant date for all or a portion of the options if
certain strategic business results are attained over the vesting period.
Awards under this program utilize shares available under both the 1991 Plan
and the 1995 Plan.
 
1997 STOCK INCENTIVE PLAN
The 1997 Stock Incentive Plan (1997 Plan) will be submitted for approval by
the Company's shareholders at the May 1997 Annual Meeting. The provisions of
the 1997 Plan will be similar to those of the 1991 Plan. During 1997, the
total number of shares expected to be available for grant under the 1997 Plan
will be 5,248,469 shares.
 
LONG-TERM INCENTIVE PLAN
The Long-Term Incentive Plan, which provided for the issuance of common shares
to key employees as either restricted stock awards or stock options,
terminated by its terms on November 9, 1991. However, the provisions of the
plan continue with respect to any restricted stock awards and stock options
granted prior to the termination date. The terms and conditions of the options
granted under this plan are similar to those under the 1991 Plan.
 
ACCOUNTING FOR STOCK AWARDS AND STOCK OPTIONS
In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation." As permitted by the standard, the Company has elected to
continue to follow existing accounting guidance, Accounting Principles Board
Opinion No. 25 and related interpretations (APB No. 25), for stock-based
compensation. However, SFAS No. 123 requires companies electing to follow
existing accounting rules to disclose in a note the pro forma effects as if
the fair value based method of accounting had been applied. The Company
recorded compensation expense of $2,154,000, $751,000 and $8,650,000 for the
years ended December 31, 1994, 1995 and 1996, respectively, in connection with
its performance shares, restricted stock and other stock compensation awards.
In accordance with APB No. 25, no compensation expense has been recognized for
the Company's stock options.

The weighted average fair value of stock options granted during each of the
years 1995 and 1996 was $5.50 and $5.84, respectively. The fair value of each
option grant is estimated on the date of grant using the Black-Scholes option-
pricing model with the following weighted average assumptions for grants in
1995 and 1996, respectively: dividend yield of 5.0 percent and 4.3 percent,
expected volatility of 19.2 percent and 17.5 percent, risk-free interest rates
of 6.9 percent and 5.4 percent, and expected lives of 4.9 years for both
years. If compensation expense for the Company's stock options granted in 1995
and 1996 had been determined based on the fair value at the grant dates for
such awards in accordance with SFAS No. 123, the effect on the Company's net
income and earnings per share for each of the years ended December 31, 1995
and 1996 would have been immaterial.

The Company granted stock awards totaling 17,000 shares in 1994, 34,000 shares
in 1995, and 103,000 shares in 1996 with weighted average market prices per

404,000 performance shares were issued during 1996 at a weighted average
market price of $45.87 per share.
 
11. PREFERRED STOCK
 
During 1996, amendments to the Company's Certificate of Incorporation were
approved to eliminate the existing authorized shares of cumulative preferred
stock and to authorize a new class of preferred stock. Accordingly, the
existing 2,500,000 authorized shares of preferred stock of $100 par value were
eliminated and replaced with 5,000,000 authorized shares of a new class of
preferred stock of $100 par value. There were no shares of preferred stock
issued or outstanding at December 31, 1995 or 1996.
 
12. DIVIDEND RESTRICTIONS
 
One of the Company's indentures relating to senior debenture issues contains
restrictions on dividend payments by the Company and acquisitions of its
capital stock. Under the indenture provisions, $613,562,000 of consolidated
retained earnings was free from such restrictions at December 31, 1996. The
indenture also imposes dividend limitations on the subsidiaries, but at
December 31, 1996, these limitations did not restrict their ability to pay
dividends to the Company.

CONSOLIDATED NATURAL GAS COMPANY AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Discounts and premiums and the expenses incurred in connection with the
issuance of debentures are being amortized on a basis which will equitably
distribute the amount to "Interest on long-term debt" over the life of each
debenture issue.

During the 1996 fourth quarter, the Company called for redemption $53,125,000
principal amount of the 8 5/8% Debentures Due December 1, 2011. In connection
with the call, the Company placed funds into an irrevocable trust in December
1996 for the sole purpose of paying the principal amount and related call
premium and accrued interest. As such, the debt has been removed from the
Consolidated Balance Sheet at December 31, 1996. Payment was made from the
trust on February 1, 1997. This transaction resulted in a 1996 charge of
$5,012,000.

The Company's 7 1/4% Convertible Subordinated Debentures, which mature on
December 15, 2015, are convertible into shares of the Company's common stock
at any time prior to maturity at an initial conversion price of $54 per share.
Under additional terms of the issue, on December 15, 2000, the Company is
obligated to purchase, at the option of the holder, any debenture then
outstanding for 100% of the principal amount plus accrued interest.

The 9.94% unsecured loan due January 1, 1999, is an obligation of Virginia
Natural Gas. This $20,000,000 loan, which is being repaid in five annual
installments of $4,000,000 each beginning January 1, 1995, has been guaranteed
by the Company.
 
14. SHORT-TERM BORROWINGS
 
The weighted average interest rate on the Company's commercial paper notes
outstanding at December 31, 1995 and 1996, was 5.79% and 5.70%, respectively.

The Company has a $475,000,000 credit agreement and a $300,000,000 credit
agreement with a group of banks. Borrowings under these agreements are in the
form of revolving credits and may, at the option of the Company, be structured
either as syndicated loans by a group of participating banks or money market
loans by individual banks. The loans may be borrowed, paid or repaid and
reborrowed on a few days notice. Varying interest rate options are available
for syndicated loans, while the interest rate on money market loans is
determined from quotes rendered by the participating banks. These agreements
may be used for general corporate purposes, including the support of
commercial paper notes. The agreements are currently scheduled to expire on
June 27, 1997; however, the Company expects that the agreements will be
renewed or replaced by comparable agreements. A facility fee is charged under
the agreements but is not considered significant. There were no borrowings
under these agreements at December 31, 1996.

DERIVATIVE FINANCIAL INSTRUMENTS AND ENERGY PRICE RISK MANAGEMENT ACTIVITIES
 
  FUTURES AND OPTIONS CONTRACTS
The Company's energy price risk management activities include exchange-traded
futures and options contracts which can be settled through the purchase or
delivery of commodities. CNG Producing uses futures and options to manage
commodity price risk in connection with the production and sale of crude oil,
while CNG Energy Services uses such instruments to manage similar risk
regarding gas and electricity purchase and sale commitments and stored gas
inventories.

At December 31, 1996, CNG Producing's price risk management activities
included crude oil futures contracts under hedging activities maturing through
December 1997 covering 444,000 barrels of oil. Also at December 31, 1996, CNG
Energy Services had natural gas futures contracts related to gas purchase and
sale commitments and gas storage inventory covering 2.5 Bcf of gas on a net
basis maturing through December 1998.

For contracts used by the Company that qualify and have been designated as
hedges, any gains or losses resulting from market price changes are expected
to be generally offset by the related physical transaction. The Company's net
unrealized gain related to futures contracts was approximately $2,300,000 at
December 31, 1996. The net unrealized loss at December 31, 1996, related to
options contracts was not material to the Company's financial position,
results of operations or cash flows.
 
  SWAP AGREEMENTS
In addition to exchange-traded futures and options contracts, the nonregulated
subsidiaries enter into OTC price swap agreements to manage their exposure to
commodity price risk under existing sales commitments. At December 31, 1996,
CNG Energy Services had swap agreements of varying duration outstanding with
several counterparties to exchange monthly payments on net notional quantities
of 33.5 Bcf of gas over the ensuing 2 years. In addition, CNG Producing
Company had one swap outstanding at December 31, 1996, to exchange payments on
net notional quantities of approximately 1 million barrels of oil through
December 1997. Net notional quantities or amounts do not represent the
quantities or amounts exchanged by the parties and, thus, are not a measure of
the exposure of the Company through its use of derivatives. The amounts
exchanged are calculated on the basis of monthly notional quantities and other
terms of the agreements. The Company's net unrealized loss related to these
swap agreements was approximately $1,100,000 at December 31, 1996. Profits
expected on anticipated sales related to the hedged transactions should
generally offset the estimated unrealized losses on the swap agreements.

CNG Energy Services also has a 10-year foreign currency swap agreement to
manage foreign exchange rate risk in connection with the payment of demand
charges for pipeline capacity in Canada. The aggregate notional amount
underlying this swap agreement was approximately $64,500,000 at December 31,
1996. The unrealized gain related to the foreign currency swap agreement was
approximately $7,300,000 at December 31, 1996.
 
  MARKET AND CREDIT RISK
The use of derivatives exposes the Company to market risk and credit risk.
Market risk represents the potential loss that can be caused by a change in
the market value of a particular commitment. Although the use of derivatives
generally reduces market risk exposure due to unfavorable price fluctuations,
such risk management activities, while not significant, can also result in the
assumption of a limited degree of price risk in certain isolated transactions.
Credit risk relates to the risk of loss that the Company would incur as a
result of nonperformance by counterparties pursuant to the terms of their
contractual obligations. The Company does not have a significant exposure to
any individual counterparty to its energy price risk management activities.
Management has operating procedures in place to evaluate market and credit
risks and believes that the Company's exposure to risks associated with
derivatives is not material in relation to the Company's financial position,
results of operations or cash flows.

16. ENVIRONMENTAL MATTERS
 
The Company is subject to various federal, state and local laws and
regulations relating to the protection of the environment. These laws and
regulations govern both current and future operations and potentially extend
to plant sites formerly owned or operated by the subsidiaries, or their
predecessors.

The Company has taken a proactive position with respect to environmental
concerns. As part of normal business operations, subsidiaries periodically
monitor their properties and facilities to identify and resolve potential
environmental matters, and the Company conducts general environmental surveys
on a continuing basis at its operating facilities to monitor compliance with
environmental laws and regulations. As part of this process, voluntary surveys
at subsidiary sites have been conducted to determine the extent of any
possible soil contamination due to hazardous substances, such as mercury, and
when contamination has been discovered remediation efforts are undertaken.
Further, on August 16, 1990, CNG Transmission entered into a Consent Order and
Agreement with the Commonwealth of Pennsylvania Department of Environmental
Resources (DER) in which CNG Transmission has agreed with the DER's
determination of certain violations of the Pennsylvania Solid Waste Management
Act, the Pennsylvania Clean Streams Law and the rules and regulations
promulgated thereunder. No civil penalties have been assessed as of this date.
Pursuant to the Order and Agreement, CNG Transmission is performing sampling,
testing and analysis, and conducting a program of remediation at some of its
Pennsylvania facilities. Total remediation costs in connection with these
sites and the Order and Agreement are not expected to be material with respect
to the Company's financial position, results of operations or cash flows.
Based on current information, the Company has recognized a gross estimated
liability amounting to $15,220,000 at December 31, 1996, for future costs
expected to be incurred to remediate or mitigate hazardous substances at these
sites and at facilities covered by the Order and Agreement.

Inasmuch as certain environmental-related expenditures are expected to be
recoverable in future regulatory proceedings, a regulatory asset amounting to
$11,047,000 at December 31, 1996, is included in the Consolidated Balance
Sheet under the caption "Deferred charges and other assets." Also, uncontested
claims amounting to $2,375,000 at December 31, 1996, were recognized for
environmental-related costs probable for recovery through joint-interest
operating agreements.

The total amounts included in operating expenses for remediation and other
environmental-related costs, and the components of such costs, are as follows:

</TABLE>
CNG Transmission and certain of the distribution subsidiaries are subject to
the Federal Clean Air Act (Clean Air Act) and the Federal Clean Air Act
Amendments of 1990 (1990 amendments) which added significantly to the existing
Clean Air Act requirements. As a result of the 1990 amendments, these
subsidiaries were required to install Reasonably Available Control Technology
at some compressor stations by May 31, 1995, to reduce nitrogen oxide
emissions. Compliance required capital expenditures to similarly retrofit some
of the compressor engines along the Company's pipeline system. The Company has
completed the installation of emission control equipment and the installation
and testing of compressor engines and related equipment required by the 1990
amendments. The 1990 amendments may also require installation of Maximum
Available Control Technology (MACT) at certain of the Company's compressor
stations to control the emissions of certain hazardous air pollutants. The
Company

CONSOLIDATED NATURAL GAS COMPANY AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

is participating with industry groups and the Environmental Protection Agency
in the development of these regulations but is unable to estimate the cost of
installing MACT, if required.

The Company expended $23.3 million in 1994, $11.3 million in 1995, and $6.8
million in 1996 to comply with the 1990 amendments. The total capital
expenditures required to comply with the 1990 amendments are expected to be
recoverable through future regulatory proceedings.

The Company has determined that it is associated with 16 former manufactured
gas plant sites, five of which are currently owned by subsidiaries. Studies
conducted by other utilities at their former manufactured gas plants have
indicated that their sites contain coal tar and other potentially harmful
materials. None of the 16 former sites with which the Company is associated is
under investigation by any state or federal environmental agency, and no
investigation or action is currently anticipated. At this time it is not known
if, or to what degree, these sites may contain environmental contamination.
Therefore, the Company is not able to estimate the cost, if any, that may be
required for the possible remediation of these sites.

The Company discovered in the course of conducting a routine environmental
survey at East Ohio Gas that some of its practices for collecting and handling
pipeline fluids that may have been contaminated with polychlorinated biphenyls
(PCBs) may not have complied with environmental regulations. The appropriate
agencies have been notified as part of the federal self-disclosure process and
discussions are continuing with the agencies to gain approval of revised
collection and handling procedures. A thorough investigation of all collection
and handling practices at East Ohio Gas is continuing and the Company
anticipates providing the results of this investigation to the appropriate
agencies in 1997. The discrepancies in the procedures were primarily in
connection with recordkeeping and did not involve spills, leaks, or other
mishandling of PCB contaminated fluids and did not damage the environment. The
Company anticipates that penalties, if any, incurred in connection with this
matter may be mitigated as a result of the Company's self disclosure. The
amount of any liabilities in connection with this matter is not expected to be
material with respect to the Company's financial position, results of
operations or cash flows.

Estimates of liability in the environmental area are based on current
environmental laws and regulations and existing technology. The exact nature
of environmental issues which the Company may encounter in the future cannot
be predicted. Additional environmental liabilities may result in the future as
more stringent environmental laws and regulations are implemented and as the
Company obtains more specific information about its existing sites and
production facilities. At present, no estimate of any such additional
liability, or range of liability amounts, can be made. However, the amount of
any such liabilities could be material.
 
17. COMMITMENTS AND CONTINGENCIES
 
Lease arrangements of the Company are principally for office space, business
machines and transportation equipment. None of these arrangements,
individually or in the aggregate, are material capital leases. Rental expense
incurred in the years 1994 through 1996 was not material, and future rental
payments required under leases in effect at December 31, 1996, are not
material.

It is estimated that the Company's 1997 capital spending program will amount
to $525,900,000, and that approximately $231,000,000 of that amount will be
directed to gas and oil producing activities. In connection with the capital
spending program, the Company has entered into certain contractual
commitments. Contractual commitments in the ordinary course of business
include requirements by CNG Energy Services to purchase capacity on
nonaffiliated pipelines to meet both committed and anticipated future long-
term customer gas supply needs.

The Company has claims and suits pending against it, but, in the opinion of
management and counsel, the ultimate liability will not have a material effect
on its financial position, results of operations or cash flows.

18. DISAGGREGATED INFORMATION
 
In addition to operating in all phases of the natural gas business, the
Company explores for and produces oil and provides a variety of energy
marketing services.

Distribution represents the retail gas distribution subsidiaries. These
subsidiaries sell gas and/or provide transportation services to residential,
commercial and industrial customers in Ohio, Pennsylvania, Virginia and West
Virginia, and are subject to price regulation by their respective state
utility commissions.

Transmission operations include the activities of CNG Transmission, an
interstate pipeline company regulated by the FERC which provides gas
transportation, storage and related services to affiliates and to utilities
and end users in the Midwest, the Mid-Atlantic states and the Northeast.
Transmission operations also include, prior to April 1, 1995, the activities
of CNG Storage. CNG Storage is engaged in providing natural gas storage
facilities and a wide range of storage-related services to affiliates and
other customers, including the sale or lease of base gas, and the sale, lease
or brokerage of gas storage capacity obtained from third parties.

(including CNG Storage), and CNG Power Services. CNG Energy Services markets
Company-owned gas production and arranges gas supplies, transportation,
storage and related services throughout North America. CNG Energy Services
also holds the Company's ownership interests in seven independent power
plants. CNG Power Services is the power marketing subsidiary that purchases
and resells electricity at market-based rates. The results of these
subsidiaries were included in the "Other" component in 1994.

The activities of CNG International, CNG Products and Services Company (CNG
Products and Services), Consolidated LNG, CNG Research Company and CNG Coal
are included in the "Other" category. CNG International was formed in 1996 to
engage in energy-related activities outside of the United States. CNG Products
and Services began operations in 1996 and provides certain energy-related
services to customers of the Company's distribution subsidiaries and others.

Transactions between affiliates are recognized at prices which approximate
market value. Significant transactions between the operating components are
eliminated to reconcile the disaggregated information to consolidated amounts.
Identifiable assets of each component are those assets that are used in its
operations.

In the foregoing determination of future cash inflows, sales prices for gas
were based on contractual arrangements or market prices at each year end.
Prices for oil were based on average prices received from sales in the month
of December each year. Future costs of developing and producing the proved gas
and oil reserves reported at the end of each year shown were based on costs
determined at each such year end, assuming the continuation of existing
economic conditions. Future income taxes were computed by applying the
appropriate year-end or future statutory tax rate to future pretax net cash
flows, less the tax basis of the properties involved, and giving effect to tax
deductions, or permanent differences and tax credits.

CONSOLIDATED NATURAL GAS COMPANY AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

It is not intended that the FASB's standardized measure of discounted future
net cash flows represent the fair market value of the Company's proved
reserves. The Company cautions that the disclosures shown are based on
estimates of proved reserve quantities and future production schedules which
are inherently imprecise and subject to revision, and the 10% discount rate is
arbitrary. In addition, present costs and prices are used in the
determinations and no value may be assigned to probable or possible reserves.

standardized measure of discounted future net cash flows at the beginning and
end of each year.

  COST-OF-SERVICE PROPERTIES
As previously stated, activities subject to cost-of-service rate regulation
are excluded from the foregoing information. At December 31, 1995 and 1996,
net capitalized costs of cost-of-service properties amounted to $14,809,000
and $10,015,000, respectively. Related proved reserves of gas and oil are
located in the United States, and amounted to 71, 56 and 43 Bcf of gas at
December 31, 1994 through 1996, and 256 thousand barrels of oil at December
31, 1994. There were no cost-of-service oil reserves at December 31, 1995 or
1996. East Ohio Gas sold all of its remaining gas and oil reserves during
1995. Hope Gas sold all of its remaining gas reserves to CNG Producing during
1996. At December 31, 1996, the Company's remaining cost-of-service gas
reserves were held by Peoples Natural Gas. Gas production for the years 1994
through 1996 amounted to 6, 4 and 3 Bcf, respectively. Oil production for 1994
and 1995 amounted to 24 and 17 thousand barrels, respectively.

Future revenues associated with production of the foregoing gas and oil
reserves would be based upon cost-of-service ratemaking and historical asset
costs, with rate of return levels determined by various state regulatory
commissions.

(B) QUARTERLY FINANCIAL DATA
A summary of the quarterly results of operations for the years 1995 and 1996
follows. Because a major portion of the gas sold or transported by the
Company's distribution and transmission operations is ultimately used for
space heating, both revenues and earnings are subject to seasonal
fluctuations, and third quarter results are usually the least significant of
the year for the Company. Seasonal fluctuations are further influenced by the
timing of price relief granted under regulation to compensate for certain past
cost increases.

(a) The 1996 first quarter includes charges related to workforce reductions
    that reduced operating income before income taxes by $3,379,000 and net
    income by $2,069,000, or $.02 per share (see Note 4 to the consolidated
    financial statements). The 1995 first quarter includes the effect of an
    impairment of gas and oil producing properties that reduced operating
    income before income taxes by $226,209,000 and net income by $145,000,000,
    or $1.56 per share (see Note 3 to the consolidated financial statements).
(b) The 1995 second quarter includes charges related to workforce reductions
    that reduced operating income before income taxes by $36,412,000 and net
    income by $23,668,000, or $.25 per share. Net income was also reduced by
    the write-down of coal properties amounting to $20,323,000, or $.22 per
    share (see Notes 3 and 4 to the consolidated financial statements).
(c) The 1995 third quarter includes charges related to workforce reductions
    that reduced operating income before income taxes by $3,457,000 and net
    income by $2,343,000, or $.02 per share (see Note 4 to the consolidated
    financial statements).
(d) The 1996 fourth quarter includes charges related to workforce reductions
    that reduced operating income before income taxes by $11,816,000 and net
    income by $7,786,000, or $.08 per share (see Note 4 to the consolidated
    financial statements).
(e) The sum of the quarterly amounts does not equal the year's amount because
    the quarterly calculations are based on a changing number of average
    shares outstanding. In addition, first quarter fully diluted earnings per
    share was $1.86.
