BUSINESS
 
    OVERVIEW
 
    Destec Energy, Inc. (together with its subsidiaries, "Destec") is one of the
largest independent producers of electricity in the world. Destec is in the
business of (i) developing, operating and managing projects which produce
electricity, thermal energy and syngas; (ii) marketing and selling electricity,
thermal energy, natural gas and lignite; and (iii) investing in projects,
entities and natural resources which support its strategic objectives. As an
independent power company, Destec has interests in 24 operating facilities, the
majority of which Destec operates and manages. All of Destec's facilities,
except the Wabash Project (defined below), produce and sell electric power, and
the majority of these facilities produce thermal energy, principally steam, to
electric utilities and energy intensive industries. Four of Destec's 24
operating facilities are located outside the United States. The combined gross
capacity of these facilities is approximately 5,136 megawatts ("MW") of
electricity and over three million pounds per hour of steam. Destec currently
has two projects, representing approximately 850 MW of capacity in construction
or advanced development. See "Destec Energy's Projects -- Projects in Operation"
and "-- Projects in Advanced Development or Under Construction."
 
    Destec is the successor to a portion of the energy businesses developed by
The Dow Chemical Company ("Dow"). Dow transferred to Destec certain assets,
technologies, personnel and expertise involved in the production and marketing
of electricity, steam and syngas. To complement these capabilities, in December
1989, Destec acquired PSE Inc., now known as Destec Holdings, Inc. ("DHI"), a
company with a 20-year history in the development, engineering, construction,
ownership and operation of gas-fired cogeneration facilities. Prior to its
initial public offering in March 1991, Destec was a wholly owned subsidiary of
Dow. Dow currently owns approximately 80.2% of Destec's outstanding common
stock. See "Recent Developments."
 
    Destec's business strategy continues to be based on being the low-cost
producer of electric power by expanding and strengthening its position as a
developer, operator and marketer of electricity, thermal energy and syngas.
Assuming the Merger (defined below) is not consummated, Destec will continue to
utilize the cash flows from its existing business to invest in and develop power
and syngas projects in domestic and international markets. See "Recent
Developments."
 
    Destec was incorporated in 1989 in Delaware. Its principal executive offices
are located at 2500 CityWest Boulevard, Suite 150, Houston, Texas 77042, and its
telephone number is (713) 735-4000.
 
RECENT DEVELOPMENTS
 
    On January 17, 1997, Tiger Bay Limited Partnership, in which Destec holds an
equity interest of approximately 50%, executed an agreement for the sale of the
nominally rated 220 megawatt Tiger Bay cogeneration facility, located in Fort
Meade, Florida to a wholly owned subsidiary of Florida Power Corporation
("Florida Power") for approximately $445 million. Destec's estimated share of
the proceeds after repayment of partnership debt and the net settlement of other
partnership obligations is anticipated to be approximately $140 million. The
sale is subject to certain conditions, including, without limitation, regulatory
approvals and the sale of Destec.
 
    On February 17, 1997, Destec executed an Agreement and Plan of Merger (the
"Merger Agreement"), by and among Destec, Dow, NGC Corporation ("NGC") and NGC
Aquisition Corporation II, a wholly owned subsidiary of NGC ("Purchaser"),
pursuant to which, among other things, Purchaser will merge with and into Destec
(the "Merger"). The surviving corporation after the Merger will be a wholly
owned subsidiary of NGC. Pursuant to the Merger Agreement, among other things,
each outstanding share of Destec's common stock, par value $0.01 per share (the
"Common Stock"), will be converted into
 
                                       1
<PAGE>
the right to receive $21.65 in cash (the "Merger Consideration"). The
consummation of the Merger is subject to certain conditions, including the
approval by the holders of at least 66 2/3% of the outstanding Common Stock, as
well as the approval by federal antitrust authorities and the Federal Energy
Regulatory Commission ("FERC").
 
DESTEC'S PRODUCTS AND SERVICES
 
    POWER PRODUCTION
 
    BACKGROUND.  The projects which Destec develops, operates and manage produce
energy in the form of electricity and syngas in cogeneration plants, exempt
wholesale generators and a coal gasification plant. A cogeneration plant
utilizes power production technology that results in the sequential generation
of two or more useful forms of energy (e.g., electricity and steam) from a
single fuel source (e.g., natural gas). The economic benefit from a cogeneration
project can be substantial, because the steam produced by a cogeneration plant
is sold to an industrial user. In contrast, exempt wholesale generators generate
electric power typically for a utility, but require no industrial user to
purchase any steam generated by the project. Destec's coal gasification plant
produces syngas, which serves as an alternative fuel in power generation
facilities.
 
    Prior to 1992, regulatory constraints prevented Destec from developing
exempt wholesale generators and limited Destec's electric power production
operations to cogeneration facilities. See "-- Domestic Power Market."
Consequently, of the 23 electric power production facilities and one operating
coal gasification facility in which Destec has an interest, 17 are cogeneration
facilities. Since 1992, however, the power industry has emphasized exempt
wholesale generators. Destec management expects that, in the future, its
electric power production operations will also emphasize exempt wholesale
generators, in addition to cogeneration projects.
 
    DOMESTIC POWER MARKET.  Historically in the United States, regulated and
government-owned utilities have been the only significant producers of electric
power for sale to third parties. The energy crisis of the 1970s led to the
enactment of the federal Public Utility Regulatory Policies Act of 1978
("PURPA"), which encouraged companies other than utilities to enter the electric
power business by reducing regulatory constraints. In addition, PURPA and its
implementing regulations created unique opportunities for the development of
cogeneration facilities by requiring utilities to purchase electric power
generated in cogeneration plants meeting certain requirements (referred to as
"Qualifying Facilities"). See "Regulatory Matters -- Energy Regulation." As a
result of PURPA, a significant market for electric power produced by independent
power producers such as Destec developed in the United States. In 1992, Congress
enacted the Energy Policy Act of 1992 ("Energy Act"), which amended the Public
Utility Holding Company Act of 1935 ("PUHCA") to create new exemptions from
PUHCA for independent power producers selling electric energy at wholesale, to
increase electricity transmission access for independent power producers and to
reduce the burdens of complying with PUHCA's restrictions on corporate
structures for owning or operating generating or transmission facilities in the
United States or abroad. The Energy Act has enhanced the development of
independent power projects and has further accelerated the changes in the
electric utility industry that were initiated by PURPA. Implementation of
federal and state policies resulting in increased availability of transmission
access for wholesale and retail transactions could create additional markets and
competition for electricity power sales.
 
    INTERNATIONAL POWER MARKET.  As a result of the increased demand for power
generating capacity around the world, the fastest growing area of the power
industry today is the international sector. This has led to increased emphasis
by foreign governments toward privatization of state-owned utilities. Experts
estimate that the international market represents 85% of the world's new and
replacement power needs. At the same time, the national, provincial and local
laws of each host country, unique political and currency exchange requirements,
and the application of new worldwide environmental standards to international
projects, create new risks and obligations to be managed.
 
                                       2
<PAGE>
    As the international market for power has continued to expand, Destec has
formed Destec Energy (Asia) Pte, Ltd., a Singapore corporation ("Destec Asia")
to provide business development services in Asia and the Far East, complementing
the business development services provided by Destec Europe, S.A. in Europe,
Africa and the Middle East. Destec's business development services in Central
and South America are provided by Destec's Houston office. Each of these offices
assist Destec in identifying opportunities for the development, acquisition or
investment in projects in their respective regions. Destec's management is
evaluating several international development and acquisition projects in areas
including Asia, Australia, the Far East, Europe, Africa, the Middle East and
Latin America.
 
    COAL GASIFICATION -- SYNGAS
 
    Syngas is produced through a coal gasification process and can be used as a
substitute fuel for natural gas in gas-fired generating facilities. Destec
produces syngas through a proprietary coal gasification process that removes
sulfur and results in lower sulfur dioxide, nitrogen oxide and carbon dioxide
emissions than alternative coal-based technologies such as pulverized coal and
circulating fluidized bed boilers. The Clean Air Act and recent amendments
thereto contain provisions that regulate the amount of sulfur dioxide and
nitrogen oxide that may be emitted by a generating project, as these emissions
may be a cause of acid rain. Compliance with these environmental emission
regulations under the Clean Air Act, especially for coal-burning facilities, may
be enhanced by use of such coal gasification technology.
 
    Key factors influencing the market potential for syngas and syngas-based
power generation include end users' commitment to coal-based energy production,
the extent of restructuring and plant life extensions of utility plants, the
availability and cost of delivered coal, the difference between natural gas and
coal prices, the availability of natural gas, regulatory efforts to reduce acid
rain and other related emissions, regulatory, strategic and legislative
incentives to utilize coal-based energy sources and the reliability and cost
effectiveness of syngas technology relative to natural gas and other coal-based
technologies. In recent years, the price of natural gas has been low relative to
the price of coal, which resulted in a shift from coal to natural gas as the
primary fuel source for new energy-producing facilities. As a result, syngas
technology has become less attractive.
 
    Destec currently has an interest in one operating facility for the
production of syngas using its proprietary technology: the Wabash River Coal
Gasification Project in West Terre Haute, Indiana ("Wabash Project"), which
commenced commercial operation in 1995. In addition, until June 1996, Destec had
an interest in a facility near Plaquemine, Louisiana (the "LGTI Facility"),
which was constructed by Dow in 1987 and which was decommissioned by Destec in
1995. Each of these facilities was designed to convert coal through a
gasification process into a refined grade of syngas suitable for use as a fuel
in gas turbines.
 
    In September 1991, the Wabash Project, a joint venture between Destec and
PSI Energy, Inc. ("PSI") was selected by the U.S. Department of Energy ("DOE")
to participate in the DOE's Clean Coal IV Program. Under this program and a
related agreement among the DOE, Destec and PSI, the DOE shares up to $219
million of the cost of the Wabash Project. In June 1996, Destec refinanced the
operating lease for the gasification portion of the Wabash Project. Under the
operating lease, a wholly owned subsidiary of Destec is the lessee and Destec
guarantees the payments of such subsidiary thereunder. The lease expires in
April 2001. Construction of the Wabash Project was completed in the third
quarter of 1995, with commercial operation achieved in the fourth quarter of
1995. After an initial demonstration period, the project is expected to operate
commercially as part of PSI's electrical generating system. Destec is currently
making improvements at the plant at an estimated cost of $14 million, with
completion expected in 1997.
 
    The LGTI Facility was constructed pursuant to an agreement with the U.S.
Department of Treasury ("Treasury Department") that required the Treasury
Department to make certain payments ("Guaranteed Payments") for the sale of
syngas when such payments were earned under the agreement, through the first
quarter of 1997. The LGTI Facility also received revenues from Dow for the sale
of syngas. Substantially all
 
                                       3
<PAGE>
of the Guaranteed Payments were earned by late 1995. In November 1995, the LGTI
Facility ceased operations and commenced decommissioning after a shutdown,
because it would not have been economical to restart and operate the plant given
that substantially all Guaranteed Payments had been earned. As a result,
approximately $0.1 million of the Guaranteed Payments will not be received. In
June 1996, Dow and Destec entered into a settlement agreement regarding the
decommissioning of the LGTI Facility under which Destec has agreed to reimburse
Dow for clean-up and disposal expenses up to a maximum of $250,000. Destec also
agreed to transfer the LGTI Facility and related equipment to Dow but retained
ownership of a slag (an inert, non-leaching ash by-product of gasification
process) pile on Dow property and will receive revenues from any Destec sale of
slag product to third parties. Destec has agreed to perform a clean closure of
the slag pile within five years.
 
    POWER MARKETING
 
    In August 1994, Destec designated a wholly owned subsidiary, Destec Power
Services, Inc. ("DPS"), to engage in the business of brokering and marketing
electric power at the wholesale level. In January 1995, Destec received approval
from the FERC to do business as a power marketer nationwide, and received the
necessary rate approvals and other regulatory exemptions for power marketing
activities. DPS has received an export permit from the Canadian National Energy
Board that authorizes the export of electricity from Canada into the United
States. DPS has also received an export license from the United States
Department of Energy that authorizes the export of electric energy from the
United States to Mexico. Formation of this subsidiary and receipt of regulatory
approval has enabled Destec to expand its range of products and enhance the
productivity and economic contribution of its existing generation assets. DPS
currently has significant power marketing activities in the States of California
and Texas. DPS is currently marketing power through its Western Operations and
Southern Operations located in Walnut Creek, California and Houston, Texas
respectively.
 
    CALIFORNIA.  Destec and Pacific Gas & Electric Company ("PG&E") have entered
into the first comprehensive control area and network transmission services
agreement between a utility and a power marketer. This agreement enables DPS to
purchase and aggregate power from a number of generating sources, including the
excess of firm contract capacity from Qualifying Facilities under contract with
PG&E. The network transmission services agreement also allows DPS to market
power directly to wholesale customers over PG&E's transmission lines. The FERC
accepted and approved this network transmission agreement in April 1995. See
"Regulatory Matters".
 
    In September 1995, DPS entered into a contract with the Port of Oakland
Authority in Oakland, California, which provides that DPS will supply seven
megawatts of electricity to The Metropolitan Oakland International Airport for
five years which commenced January 1, 1996. Transmission services are provided
under the control area and network transmission agreement. The management of
Destec believes that the contract is a first between a power marketer and a full
requirements customer. In addition, DPS continues to pursue power marketing
agreements to enable DPS to secure low cost energy for marketing and to market
that energy to potential purchasers. PG&E has resisted DPS's attempt to
aggressively pursue various facets of such California wholesale opportunities.
 
    TEXAS.  Pursuant to an agreement between Destec and Dow, Destec provided
administrative, business management and marketing services with respect to
excess capacity and energy produced by Dow's Freeport, Texas cogeneration
facilities. Prior to expiration of a power sales agreement between Texas
Utilities Electric Company ("TUEC") and Dow in April 1995, Destec marketed 100
MW to TUEC. Since the expiration of this agreement, DPS has marketed, on behalf
of Dow, certain excess capacity and energy to purchasers from time to time and
has been compensated by Dow for such services.
 
    For power marketing in Texas, Destec has focused on maximizing the value of
uncommitted capacity and energy from existing Texas operating projects and
through market opportunities. Through its Southern Operations, DPS is marketing
capacity, energy, and ancillary services to several utilities and power
 
                                       4
<PAGE>
marketers including Central and Southwest Services, Inc, ("CSW"), Houston
Lighting & Power Company ("HL&P"), The Lower Colorado River Authority ("LCRA"),
South Texas Electric Cooperative ("STEC"), Texas-New Mexico Power Co. ("TNP"),
Enron Power Marketing and LG&E Power Marketing. In addition to these spot sales
and short-term contracts, DPS has a long-term contract with LCRA for capacity
and associated energy (up to 230 MW) and is nearing approval of a long-term,
full-requirements contract with another utility. DPS' Southern Operations also
markets power from the CoGen Lyondell facility (the "CLI Facility") and other
non-utility facilities and coordinates with other generators within the Electric
Reliability Council of Texas ("ERCOT") to market ancillary services.
 
    In February 1996, CoGen Lyondell, Inc., a wholly owned subsidiary of Destec
("CLI"), and Lyondell Petrochemical Company ("LYO") formed a partnership that
was to sublease a portion of the CLI Facility. It was anticipated that the power
generated at the CLI Facility would be distributed to CLI and LYO in proportion
to their partnership percentages, pursuant to the self-generation exception
under the Texas Public Utility Regulatory Act. HL&P challenged the partnership
on the basis that the distribution of electricity under the partnership
structure would constitute a retail sale of electricity. A decision in HL&P's
favor was rendered in Austin District Court in September 1996. Destec is
currently pursuing an appeal of this decision. All deliveries of power from the
CLI Facility to LYO through a private transmission line have been postponed
indefinitely pending appeal.
 
    Destec and DPS are attempting to negotiate new contracts for the sale of
power to industrials, utilities, municipalities, cooperatives and other
wholesale customers. No assurances, however, can be made that new contracts will
be obtained. In addition, the revenues generated from any new contracts will
likely not replace the revenue and gross margin under the agreement with Dow
relating to Dow's Freeport facility. The final negotiated price and quantity for
electricity sold under any contracts that are entered into may differ from the
previous or existing contracts. Contracts having significantly different terms
than the previous contracts substantially reduced Destec's revenues and its
gross margin in 1995 and 1996. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
    In Texas, Destec is seeking legislative and regulatory changes which, if
enacted, would open additional Texas markets to independent power producers.
Certain regulatory proceedings at the PUCT may also affect future power sales in
Texas. See "Regulatory Matters -- State Regulation."
 
    PROJECT SERVICES
 
    Since its formation, Destec has utilized its expertise and significant
experience in the areas of development, engineering, environmental affairs,
operating services and management and fuel supply services of energy-producing
projects. These capabilities have also been used by Destec in evaluating
potential investment opportunities in both domestic and international markets.
 
    DEVELOPMENT.  The primary factors considered by management in evaluating
potential development, operation and investment opportunities continue to be the
anticipated rate of return on equity investment and cash flow of the project,
the existing and potential future relationship between Destec and the customer,
the availability and reliability of the fuel source and the existing and
potential competition for the proposed project. In particular, in the area of
international development, Destec seeks strategic international partners to
co-develop projects and share project risks. Destec continues to expect a
portion of its growth over the next few years to result from acquisitions of
industry-related operations, both in the United States and internationally.
 
    ENGINEERING.  Destec Engineering, Inc. ("Destec Engineering"), a wholly
owned subsidiary of Destec, historically provided expertise on engineering
processes, environmental permitting and conceptual and physical design to
enhance the construction and operation of Destec's cogeneration and independent
power projects and facilitate a smooth transition from the construction to the
operational stage of a project. As a result of Destec's new business strategy
adopted in 1994, Destec has changed the role of
 
                                       5
<PAGE>
Destec Engineering. Destec Engineering's current role is to manage the
outsourced engineering contractors for each Destec project. Such management also
includes the oversight of all conceptual planning, feasibility studies,
environmental studies and plant, engineering and construction design. As to
those projects currently under active development, Destec Engineering continues
to serve in a more comprehensive role for the engineering and construction of
these projects. See Note 18 of the Notes to Consolidated Financial Statements
for a description of the restructuring.
 
    OPERATING SERVICES.  Destec currently provides, through certain of its
wholly owned subsidiaries (collectively, the "Operating Companies"), operating
services for 17 of the 24 power producing facilities in which it has an
interest. The Operating Companies provides these facilities with specialized and
comprehensive operating, maintenance, testing and start-up services. The
employees of the Operating Companies have developed experience and knowledge
from working with gas turbines that allows them to quickly and cost-effectively
develop solutions to problems without relying on manufacturer's representatives.
This translates into high availability and high reliability, as well as
efficient plant operations. One of Destec's Operating Companies also provides
services for the Wabash Project in Indiana, applying its syngas experience from
the LGTI Facility in Louisiana.
 
    MANAGEMENT AND FUEL SUPPLY SERVICES.  Asset management services are being
provided on 19 of the 24 projects in which Destec holds an interest. The
objective of the asset management group is to maximize the near-term and
long-term value of a project and ensure that the project owners are well
informed on both the financial and operating results of the project. To ensure
the ongoing profitability of each project, the asset management group
coordinates project activities with, and maintains relationships among, all
project stakeholders, which include owners, customers, lenders, suppliers, and
operators. Various activities are performed to obtain the ongoing profitability,
including: (i) negotiating new contracts and/or amending existing contracts,
(ii) developing annual and long-term business plans and forecasts, (iii)
developing and implementing profit improvement opportunities, (i.e. fuel
hedging, refinancing of project debt, capital improvements, and maintenance
scheduling), (iv) monitoring regulatory, legislative, and environmental affairs,
and (v) providing various accounting and financial services.
 
    ENERGY RESOURCES
 
    Destec owns, manages and invests in certain natural resource assets in
support of its strategic objectives.
 
    LIGNITE.  Lignite is a low rank of coal containing 20-45% moisture as mined
and having heating values of 5,500-8,300 Btu per pound. Destec controls lignite
deposits and other lignite-related properties located in two Texas counties,
comprising an aggregate of approximately 77,500 acres. Approximately 9,900 acres
of the total are owned in fee, and approximately 67,600 acres are held under
lease. The total tonnage of lignite owned, managed or leased by Destec is
estimated by Destec to be approximately 640 million tons.
 
    Destec has leased 54,000 acres of these lignite properties to Dow under a
capital lease which requires rental payments to be made to Destec and provides
an option to Dow to purchase such properties at their book value plus cumulative
royalties. In February 1997, Dow delivered notice to Destec that it is
exercising such option and that the exercise price will be paid immediately
prior to the effective time (the "Effective Time") of the Merger. In connection
with the exercise of the option, the parties have agreed to terminate the
capital lease effective as of the Effective Time.
 
    Pursuant to an agreement between HL&P and Dow, Dow leased to HL&P certain of
its lignite properties and assigned to HL&P certain lignite leases held by Dow.
With respect to all of the properties covered by the agreement, Dow received an
initial down payment from HL&P and continues to receive quarterly installment
payments under the lease. The full amount of HL&P's down payment is being
recouped by HL&P through an offset of 25% of the quarterly installment payments
made to Dow by HL&P. The down payment is expected to be fully recouped in 1997.
Dow has assigned to Destec the right
 
                                       6
<PAGE>
to receive Dow's installment payments. The installment payments are based on a
specified rate, adjusted for inflation.
 
    OIL AND GAS.  In 1996, Destec continued to focus on maximizing the value of
its core producing areas, the San Juan Basin in New Mexico and, Colorado, and
the Antrim Shale formation in Michigan. In addition, in May 1996 Destec agreed
to acquire an interest in proved producing natural gas properties associated
with the Piceance Basin in western Colorado. Destec also owns oil and gas
mineral interests in the Cotton Valley Pinnacle Reef trend in East Texas.
Destec's portfolio of properties includes interests in 157,452 gross acres and
60,217 net acres and 457 gross producing natural gas wells. Destec has focused
its acquisition and development of gas reserves in areas that can benefit from
new technology. These include the improvements in the completion and production
technology of gas wells producing from coalbed methane reservoirs in the San
Juan Basin in New Mexico and the Antrim Shale in Michigan and tight gas sands in
the Piceance Basin of Colorado.
 
    In all cases, Destec does not serve as the operator of the properties in
which it owns an interest. Destec continues to aggressively pursue large
conventional gas reserve acquisition opportunities that strategically fit within
Destec's business development strategy. In the natural resource area, Destec
competes with other companies which have interests in lignite, oil and gas.
 
DESTEC ENERGY'S PROJECTS
 
    PROJECTS IN OPERATION
 
    Destec has significant interests in 24 power projects, each listed below,
most of which utilize the technology and expertise developed by Destec. In July
1996, Destec completed the sale of its ownership interest in the 150 MW Blue
Mountain Power project and, therefore, this project is not included in the
following table. Sales revenues are recognized for the sale of electricity and
steam, but not for operating and management services, from the CoGen Lyondell
and CoGen Power facilities. Operating results, through December 31, 1996, for 20
projects were accounted for by Destec under the equity method of accounting.
Other than the Black Mountain, Commonwealth Atlantic, Crockett CoGen, Hartwell,
Indian Queens, Oyster Creek and Hazelwood projects, each of these projects was
designed, developed and is currently operated by Destec. Destec's share of
earnings from equity investments in these operating projects accounted for
approximately 33%, 27% and 6% of Destec's income before taxes for the years
ended December 31, 1996, 1995 and 1994. See "Management's Discussion and
Analysis -- Results of Operations."

    PROJECTS IN ADVANCED DEVELOPMENT OR UNDER CONSTRUCTION
 
    Destec is committed to pursuing opportunities to develop power projects in
the United States and internationally, and to seek new applications for its
power generation technology. Among the principal items involved in developing a
project are obtaining a commitment to purchase electric power and steam,
negotiating fuel supply and transportation contracts, selecting a site,
obtaining environmental and other governmental permits and approvals,
negotiating engineering contracts and arranging financing. These items are often
obtained independently of one another and success in obtaining one such item
does not necessarily result in success in obtaining any of the others. No
assurance can be given by Destec that all necessary items will be successfully
obtained for any of the projects currently in development or that any of the
projects discussed below will ultimately be completed. Management estimates that
a project requires from three to five years from opportunity identification to
the completion of financing.
 
    The following table describes Destec's power projects currently under
construction or in advanced development and for which either an electric power
sales contract has been signed or a firm commitment for a substantial amount of
the project's output has been received. All information is provided based on the
status of such projects as of December 31, 1996, and is subject to change during
development and construction.

COMPETITION
 
    COMPETITION IN THE POWER MARKET
 
    The independent power industry has grown rapidly over the past twenty years.
The demand for power may be met by generation capacity based on several
competing technologies, such as gas-fired or coal-fired cogeneration and power
generating facilities fueled by alternative energy sources including hydro
power, synthetic fuels, solar, wind, wood, geothermal, waste heat, solid waste
and nuclear sources. Destec competes with other non-utility generators,
regulated utilities, unregulated subsidiaries of regulated utilities and other
energy service companies in the development and operation of energy-producing
projects and the marketing of electric power. In the United States, the Energy
Act reduces certain restrictions currently applicable to certain projects which
are not Qualifying Facilities (as further defined below) under PURPA and
provides for the removal of certain impediments to competition in the power
generation industry. Although the provisions of the Energy Act apply only to
wholesale transactions, actions by many state authorities are also increasing
competition for industrial, commercial and other
 
                                       9
<PAGE>
larger scale customers in the provision of services by Qualifying Facilities,
and independent power projects, as well as power marketers and other unregulated
suppliers. The development rights of Qualifying Facilities, which were
facilitated by certain provisions of PURPA, have not been affected, nor amended,
by the Energy Act. However, proposed legislation has been introduced in Congress
to repeal all or part of PURPA. These federal legislative proposals would not
abrogate or amend existing contracts with electric utilities and would only be
effective prospectively for new contracts.
 
    Legislation to repeal PUHCA is also currently pending in Congress. Although
passage of stand alone legislation repealing PUHCA is not expected during the
current session, eventual repeal or modification of PUHCA is being considered.
Congressional repeal or modification of PUHCA will loosen the strictures
currently placed on utilities and others from acquiring generation and
transmission assets outside of their service territories. This will
significantly increase the competition Destec faces both domestically and
internationally.
 
    The industry is presently characterized by rapid change in the regulatory
and commercial aspects of competition. Although the timing and ultimate effect
of these changes cannot be predicted, management of Destec believes that the
overall effect of the current changes will be to increase competition in the
generation, transmission and sale of electric power. See "Regulatory Matters --
Transmission and Wheeling."
 
    COMPETITION IN THE COAL GASIFICATION-SYNGAS MARKET
 
    In marketing the syngas produced by Destec's coal gasification technology,
Destec competes primarily with other major syngas producers, natural gas
suppliers and other coal technologies. Management believes that certain features
of Destec's proprietary coal gasification technology make it more energy
efficient and lower in capital costs than other coal gasification technologies.
Increased Clean Air requirements and market receptivity for clean coal
technologies may enhance the attractiveness of coal gasification technology for
the remainder of this decade. However, there are many other factors affecting
the development of syngas plants based on coal gasification technology,
including the price of competing fuels, such as natural gas, and the extent of
government participation in the development of alternative fuel technologies.
See "Destec's Products and Services -- Coal Gasification-Syngas" for a
discussion of these factors. At the present time, the cost of syngas relative to
competing fuels is adversely affecting the market for these plants. No assurance
may be given as to the likelihood or timing of any change in these factors.
Management of Destec believes that the largest market for coal gasification
technology may be outside North America, where coal is a more attractive fuel.
 
REGULATORY MATTERS
 
    Destec is subject to various energy and environmental laws and regulations
at the federal, state and local levels in connection with the development,
ownership and operation of its projects and the sale of energy. Federal laws and
regulations developed by administrative agencies govern transactions with
utility companies, the types of fuel which may be utilized by a project, the
type of energy which may be produced by a project and the ownership and transfer
of interests in a project. State utility regulatory commissions must often
approve the rates and, in some instances, other terms and conditions on which
public utilities purchase electric power from Destec's projects. Under certain
circumstances where specific federal exemptions are otherwise unavailable, state
utility regulatory commissions may have broad jurisdiction over electric power
contracts. Energy-producing projects are also subject to federal, state and
local laws and administrative regulations which govern the emissions and other
substances produced by a project, as well as the geographical location, zoning,
land use and operation of a facility. Applicable federal environmental laws
typically have state and local enforcement monitoring and implementation
provisions. These environmental laws and regulations generally require that a
wide variety of permits and other approvals be obtained before the commencement
of construction or operation of an energy-producing facility and that the
facility then operate in compliance with such permits and approvals.
 
                                       10
<PAGE>
    Development of projects in international markets also creates exposure and
obligations to the national, provincial and local laws of each host country,
unique political and currency exchange requirements, the application of PUHCA to
international projects, worldwide environmental standards and requirements
imposed by multi-lateral lending institutions. Destec identifies and manages
those issues early in the development process to ensure compliance with such
laws and regulations.
 
    Destec believes it is possible that changes in PURPA, PUHCA and other
related federal statutes may occur in the next several years. The nature and
impact of such changes on Destec's projects, operations and contracts is unknown
at this time. Destec is actively monitoring these developments directly and
through industry trade groups to determine such impacts as well as to evaluate
new business opportunities created by restructuring of the electric power
industry. Depending on the outcome of these legislative matters, changes in
legislation could have an adverse effect on current contract prices.
 
    ENERGY REGULATION
 
    As described below, the exemptions from extensive federal and state
regulation afforded by PURPA to Qualifying Facilities are important to Destec
and its competitors. Many of the projects that Destec currently owns meet the
requirements under PURPA to be Qualifying Facilities and are maintained on that
basis. As to those projects which are independent power projects, Destec has
structured them to ensure the necessary exemptions from PUHCA and state
regulation. Additionally, regulatory impositions on power marketing operations
are expected to be minimal under existing regulatory standards.
 
    PURPA.  The enactment in 1978 of PURPA and the adoption of regulations
thereunder by the FERC provide incentives for the development of small power
production facilities and cogeneration facilities meeting certain criteria. In
order to be a Qualifying Facility, a cogeneration facility must (i) produce not
only electricity but also a certain quantity of thermal energy (such as steam)
which is used for a purpose other than power generation, (ii) meet certain
energy operating and efficiency standards when oil or natural gas is used as a
fuel source and (iii) not be controlled or more than 50% owned by an electric
utility or electric utility holding company, or any combination thereof.
 
    PURPA provides two primary benefits to Qualifying Facilities owned and
operated by non-utility generators. First, Qualifying Facilities under PURPA are
exempt from certain provisions of PUHCA, the Federal Power Act (the "FPA") and,
except under certain limited circumstances, state laws respecting rate and
financial regulation. Second, PURPA requires that electric utilities purchase
electricity generated by Qualifying Facilities at a price equal to the
purchasing utility's full "avoided cost" and that the utility sell back-up power
to the Qualifying Facility on a non-discriminatory basis. Avoided costs are
defined by PURPA as the "incremental costs to the electric utility of electric
energy or capacity or both which, but for the purchase from the Qualifying
Facility or Qualifying Facilities, such utility would generate itself or
purchase from another source." The FERC regulations also permit Qualifying
Facilities and utilities to negotiate agreements for utility purchases of power
at rates other than the purchasing utility's avoided cost. Although public
utilities are not required by PURPA to enter into long-term contracts, PURPA
helped to create a regulatory environment in which it has become more common for
such contracts to be negotiated or executed through selective procurement or
competitive bidding. If Congress amends PURPA, the statutory requirement that an
electric utility purchase electricity from a Qualifying Facility at full avoided
costs could be eliminated. Although current legislative proposals specify the
honoring of existing contracts, repeal of the statutory purchase requirements of
PURPA going forward could increase pressure to renegotiate existing contracts.
Any changes which result in lower contract prices could have an adverse effect
on Destec's operations and financial position. See "Competition -- Competition
in the Power Market."
 
    PUHCA.  Under PUHCA, any person (defined by PUHCA to include corporations
and partnerships and other legal entities) which owns or controls ten percent or
more of the outstanding voting securities of a "public utility company" or a
company which is a "holding company" of a "public utility company" is
 
                                       11
<PAGE>
subject to registration with the Securities and Exchange Commission (the
"Commission") and regulation under PUHCA, unless such person is eligible for an
exemption, such as is available to Qualifying Facilities under PURPA, or as
established elsewhere under PUHCA. A registered holding company is required by
PUHCA to limit its operation to a single integrated utility system and to divest
any other operations not functionally related to the operation of that utility
system.
 
    The Congress passed the Energy Act to promote further competition in the
development of new wholesale power generation sources. Through amendments to
PUHCA, the Energy Act encourages the development of independent power projects
which will be certified by the FERC as exempt wholesale generators ("EWGs"). The
owners or operators of these facilities are exempt from the provisions of PUHCA.
The Energy Act also provides the FERC with extensive new authority to order
electric utilities to provide other electric utilities, Qualifying Facilities
and independent power projects with access to their transmission systems.
However, the Energy Act does preclude the FERC from ordering transmission
services to retail customers and prohibits sham wholesale energy transactions
which appear to provide wholesale service, but actually are providing service to
retail customers.
 
    A company engaged in the ownership or operation of electric power generation
and transmission facilities faces certain types of regulation for its
international activities. The principal regulatory consideration for
international projects is PUHCA, since it is broadly applicable to the ownership
and operation of power facilities (including generation and transmission
facilities) both inside and outside of the United States. For international
projects, the principal basis for exemption from PUHCA is by obtaining EWG
status from the FERC. EWG status is even more beneficial for international
projects because, although EWGs are not permitted to make retail sales in the
United States, retail sales by EWGs are generally allowed in international
markets. Another way to obtain an exemption from PUHCA for foreign ownership and
operation activities is by filing a foreign utility company determination
("FUCO") with the Commission. However, FUCO filings are less frequently used,
because unlike EWGs, no formal regulatory order is issued confirming the status
of a FUCO, and more rigorous state commission scrutiny is entailed.
 
    Structuring Destec's activities to ensure that it is not a "holding company"
of a "public utility company" under PUHCA is also important in providing
financing and financial reporting flexibility to Destec. The cogeneration
facilities owned by Destec, or in which Destec has investments, are Qualifying
Facilities under PURPA. Destec has also pursued the development of independent
power projects which will not qualify for the benefits provided by PURPA, which
could subject these projects to PUHCA jurisdiction. To avoid such a consequence,
Destec has structured its participation in independent power projects in a
manner to qualify for exemptions under PUHCA provided by the Energy Act. Such
structures have permitted Destec to take ownership positions in a number of
independent power project projects. This strategy will protect the status of
Destec's existing cogeneration facilities as Qualifying Facilities under PURPA,
and not create adverse regulatory consequences.
 
    The development of international power generation and transmission projects
also may entail other multi-national regulatory considerations arising under
United States law. Certain requirements exist for compliance with the Foreign
Corrupt Practices Act, and export/import controls and related trade laws may
apply to certain transactions. Free trade agreements may exist with certain
countries, such as Canada and Mexico, which can have important relevancy in the
structuring of business transactions in these markets. World Bank standards
exist for environmental regulations which also must be considered. Finally, tax
treaties may create certain requirements for project structuring to maximize the
tax planning and benefits to Destec. Destec seeks compliance with these
requirements in the project development and financing of its international
projects.
 
    FPA.  The FPA grants the FERC exclusive rate-making jurisdiction over
wholesale sales of electricity in interstate commerce. The FPA provides the FERC
with ongoing as well as initial jurisdiction, enabling the FERC to revoke or
modify previously approved rates. Such rates may be based on a cost-of-service
approach or on rates that are determined through competitive bidding or
negotiation on a market basis.
 
                                       12
<PAGE>
Although Qualifying Facilities under PURPA are exempt from rate-making and
certain other provisions of the FPA, independent power projects and certain
power marketing activities are subject to the FPA and to the FERC's rate-making
jurisdiction.
 
    Utilities are not obligated to purchase power from projects subject to
regulation by the FERC under the FPA because they do not meet the requirements
of PURPA. However, because such projects would not be bound by PURPA's thermal
energy use requirement, they may have greater latitude in site selection and
facility size. All of the projects currently owned or operated by Destec as
Qualifying Facilities under PURPA are exempt from the FPA. Destec's EWGs,
Commonwealth Atlantic and Hartwell, are subject to the FPA and the jurisdiction
of the FERC, as is DPS. FERC has significantly relaxed the rules under which
power marketers and independent power producers, such as DPS and Destec's EWGs,
can sell or market power. With approval from FERC, such entities, with certain
exceptions, are exempted from cost-based rates and can make all sales at
market-based rates set through negotiations. Independent power projects in which
Destec currently participates have been granted market based rate authority and
comply with the FPA requirements governing approval of wholesale rates and
subsequent transfers of ownership interest in such projects.
 
    STATE REGULATION
 
    State public utility commissions, pursuant to state legislative authority,
will have jurisdiction over how any new federal initiatives are implemented in
each state and have broad jurisdiction over regulated independent power projects
which are not Qualifying Facilities under PURPA, and which are considered public
utilities in many states. Such jurisdiction would include the issuance of
certificates of public convenience and necessity to construct a facility as well
as regulation of organizational, accounting, financial and other corporate
matters on an ongoing basis. Although the FERC generally has exclusive
jurisdiction over the rates charged by an independent power project to its
wholesale customers, state public utility commissions have the practical ability
to influence the establishment of such rates by asserting jurisdiction over the
purchasing utility's ability to pass through the resulting cost of purchased
power to its retail customers. In addition, states may assert jurisdiction over
the siting and construction of independent power projects and, among other
things, issuance of securities, related party transactions and sale and transfer
of assets. The actual scope of jurisdiction over independent power projects by
state public utility regulatory commissions varies from state to state.
 
    In Texas, unless otherwise exempted, the terms of supply contracts with
electric utilities are subject to review each time the utility seeks an
adjustment in the rates charged to its customers. Accordingly, during the entire
term of any contracts Destec has with utilities in Texas, such contracts are
subject to review by the Public Utility Commission of Texas ("PUCT").
 
    The Texas Legislature passed a revised Public Utility Regulatory Act
("PURA") in 1995. This legislation recognizes power marketers and EWGs as
entities entitled to conduct business in Texas. Destec, through DPS, has
registered and is doing business as a power marketer in Texas. The legislation
also mandates that wholesale transmission service(s) in Texas meet federal
standards for non-discrimination and comparability. The PUCT conducted
rulemakings and other proceedings to implement these requirements and, as a
result, rules have been promulgated and transmission rates and terms and
conditions established. Non-discriminatory transmission tariff provisions for
the purchase and sale of ancillary serves, and an Independent System Operator
("ISO") to coordinate transmission within ERCOT have also been approved. PURA
also required the PUCT to study and submit reports on industry structure
(Project 15000), stranded investment (Project 15001), and the status of
competition (Project 15002) the reports were submitted January 15, 1997. Destec
actively participated in such proceedings. The 1997 Texas legislative session is
addressing further changes to the electric industry. While the final outcome of
any such legislation is uncertain, bills have been introduced that call for
retail access and customer choice beginning in 1999.
 
                                       13
<PAGE>
    In August 1996 the California State Legislature unanimously passed, and the
Governor signed, Assembly Bill 1890, the country's first comprehensive electric
industry restructuring legislation. The bill incorporates most of the California
Public Utilities Commission ("CPUC") December 1995 order regarding timing,
market structure, and transition issues. The law will enable California electric
consumers to have "direct access" to, and be able to choose among competing
suppliers of electricity. The bill codifies into law the January 1, 1998 start
date for the new market structure to be in place. It also calls for the creation
of a wholesale power pool ("Power Exchange"), the establishment of an ISO to
manage and control the transmission facilities, and the recovery by the
utilities of their "stranded cost" (i.e., incurred cost which can not be
recovered under market-pricing), including certain costs payable pursuant to
standard offer contracts, through a "competition transition charge."
Implementation of the restructuring called for by the new law will require
numerous state and federal regulatory filings and approvals, many of which are
currently in progress.
 
    TRANSMISSION AND WHEELING
 
    Energy-producing projects that sell power to customers which are not
geographically located near the project require that the project have the
capability of transmitting its power over utility power transmission grids to
the purchaser ("wheeling"). The FERC and state utility regulatory commissions
have jurisdiction over the wheeling of power to remote users; the prices and
related terms and conditions of wheeling in interstate commerce are regulated by
the FERC.
 
    The PUCT has promulgated rules that require affected utilities to provide
wheeling service. These rules are in effect in the Electrical Reliability
Counsel of Texas system and the new transmission access provisions of the Energy
Act do not alter that federal and state jurisdictional balance.
 
    Rules adopted at the FERC and a number of state utility regulatory
commissions require utilities to grant power producers increased access to
transmission and wheeling. The provisions of the Energy Act increase such
access. The Energy Act supports increased transmission access, and in April 1996
the FERC adopted rules (Order 888) to expand significantly transmission service
and access and provide alternative methods of pricing for transmission services.
Upon promulgation of the final rule by the FERC (and the PUCT for ERCOT), the
interstate transmission grid in the continental United States was opened to all
qualified persons that seek transmission services to wheel wholesale power.
Utilities are required to provide transmission customers non-discriminatory open
access to their transmission grids with rates, terms, and conditions comparable
to that which the utility imposes on itself. This provides Destec with increased
opportunities to sell and market the power produced by its independent power
projects. It also increases competition on a nationwide basis between
traditional and non-traditional power generators, such as Destec.
 
    ENVIRONMENTAL REGULATION
 
    The construction and operation of domestic and international energy and fuel
producing projects and the exploitation of natural resource properties are
subject to extensive federal, state and local laws and regulations adopted for
the protection of the environment and to regulate land use. The laws and
regulations applicable to Destec and projects in which it participates primarily
involve the discharge of emissions into the water and air, but can also include
wetlands preservation, noise regulation and a comprehensive Environmental Impact
Assessment which includes evaluation of the facility's impact on air, water,
ecology, human health and socioeconomic factors. These laws and regulations in
many cases require a lengthy and complex process of obtaining licenses, permits
and approvals from federal, state and local agencies. Obtaining necessary
approvals regarding the discharge of emissions into the air is critical to the
development of a project and can be time-consuming and difficult. Each
energy-producing project requires technology and facilities which comply with
federal, state and local requirements and sometimes extensive negotiations with
administrative agencies. Meeting the requirements of each jurisdiction with
authority
 
                                       14
<PAGE>
over a project can delay or sometimes prevent the completion of a proposed
project, as well as require extensive modifications to existing projects.
 
    Destec monitors environmental standards and evaluates its selection of
technology to ensure that applicable standards are being met. Based on current
trends, Destec expects that environmental and land use regulation will become
more stringent. Accordingly, Destec plans to continue to place a strong emphasis
on the development and use of state-of-the-art technology to minimize potential
impacts on the environment. In addition, Destec has developed expertise and
experience in obtaining necessary licenses, permits and approvals.
 
    In November 1990, comprehensive amendments to the Clean Air Act were enacted
(the "1990 Amendments"). The first major revisions to the Clean Air Act since
1977, the 1990 Amendments vastly expand the scope of federal regulations and
enforcement in several significant respects. In particular, provisions relating
to non-attainment, air toxics, permitting, enforcement and acid deposition may
affect Destec's domestic projects. The Clean Air Act and the 1990 Amendments
contain provisions that regulate the amount of sulfur dioxide and nitrogen
oxides that may be emitted by a project. These emissions may be a cause of "acid
rain." Most of the domestic projects Destec owns, operates and has investments
in are fueled by natural gas and are not expected to be significantly affected
by the acid rain provisions of the 1990 Amendments. Destec's coal gasification
technology for the production of syngas is drawing interest from parties
attempting to determine ways to meet the acid rain provisions of the 1990
Amendments because the sulfur dioxide and nitrogen oxides emissions associated
with this technology are relatively low. Destec currently leases one such coal
gasification plant which is in operation in Indiana. See "Destec's Products and
Services -- Coal Gasification -- Syngas." In addition, carbon dioxide emissions
from Destec's coal gasification technology are among the lowest of all
commercially available coal-based systems.
 
    One of the key elements of the 1990 Amendments is the inclusion of an
operating permit program in Title V. This program is intended to establish a
central point in tracking all applicable air quality requirements for every
source required to obtain a permit under the Clean Air Act. Final regulations
implementing these provisions were issued by the EPA in 1992. These regulations
created minimum requirements for the operating permit program. Each state was
required to submit a program for its implementation of the regulations for
approval to the EPA. Destec is required to submit complete operating permit
applications to those states in which it has operating projects which meet the
applicability standards under the 1990 Amendments. These new requirements affect
all of Destec's domestic operating facilities, except for Cogen Power, which is
not a source of pollutant emissions.
 
LEGAL PROCEEDINGS
 
    Destec experiences routine litigation in the normal course of its business.
None of its pending litigation is expected to have a material effect on the
financial condition of Destec.
 
EMPLOYEES AND OFFICES
 
    As of March 10, 1997, Destec had 668 active employees. None of Destec's
employees are covered by a collective bargaining agreement.
 
    Destec leases its corporate headquarters in Houston, Texas and its regional
offices in Las Vegas, Nevada; Walnut Creek, California; North York, Ontario,
Canada; Chapultepec, Mexico; Sevres, France; and Singapore. Destec owns a
building in Bakersfield, California that serves as a central support facility
for its California projects.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
    Management's Discussion and Analysis of Financial Condition and Results of
Operations includes certain forwardlooking statements reflecting the Company's
expectations in the near future; however, many factors which may affect the
actual results, especially contract prices and changing regulations, are
difficult to predict. Accordingly, there is no assurance that the Company's
expectations will be realized.
 
    The following discussion should be read in conjunction with the consolidated
financial statements and notes thereto and the comparative summary of selected
financial data appearing elsewhere in this report. Historical results and trends
which might appear should not be taken as indicative of future operations.
 
                                       17

OVERVIEW
 
    Destec is an independent power producer and marketer of electricity, thermal
energy and syngas. In February 1997, Destec announced that its Board of
Directors (the "Board") had approved a Merger Agreement under which NGC
Corporation ("NGC") will acquire Destec in a merger ("Merger") for $21.65 in
cash for each outstanding share of Destec common stock, or approximately $1.27
billion in the aggregate. Following the Merger, Destec will become a wholly
owned subsidiary of NGC. The consummation of the Merger is subject to certain
conditions, including approval by holders of two-thirds of the outstanding
shares of common stock and by federal antitrust authorities and the Federal
Energy Regulatory Commission. The Dow Chemical Company ("Dow"), which owns over
80% of the outstanding common stock as of December 31, 1996, has agreed to vote
its shares of common stock for approval and adoption of the Merger. In January
1997, Tiger Bay Limited Partnership, in which Destec holds an equity interest of
approximately 50%, executed an agreement for the sale of the Tiger Bay
cogeneration facility, located in Fort Meade, Florida to a wholly owned
subsidiary of Florida Power Corporation for $445.0 million. Destec's estimated
share of the proceeds after repayment of partnership debt and the net settlement
of other partnership obligations is anticipated to be approximately $140.0
million. The sale is subject to certain conditions, including regulatory
approvals and the sale of Destec. See Note 22 of the Notes to Consolidated
Financial Statements for additional discussion. Destec's project portfolio
includes a total of twenty-four operating or substantially completed projects
consisting of nineteen power projects in the U.S., one syngas project in the
U.S. and four international power projects located in Australia, Canada, the
Dominican Republic and the United Kingdom. During 1996, Destec received revenues
from the sale of electricity, thermal energy and syngas from Destec's owned or
leased projects and from power marketing revenues earned by Destec Power
Services, Inc. ("DPS"). These revenues and revenues earned in 1995 from the sale
of syngas to Dow and from the sale of power from Dow's Freeport facility under
the Power Marketing Agreement ("PMA") are classified as "Power, steam and
syngas" in the "Summary of Statements of Consolidated Income" presented below.
Destec also received revenue from its oil and gas properties and lignite
properties (classified as "Energy resources"), from fees earned in connection
with its activities as an engineer and operator of various cogeneration projects
(classified as "Engineering and operations") and from fees earned as a developer
of power generation projects (classified as "Development"). The related costs
for each of these activities appears in the corresponding section of the summary
as "Operating Costs and Expenses." Gross margin for these activities represents
revenues less the related operating costs.
 
DOMESTIC POWER
 
    Destec owns, leases or has an equity interest in nineteen operating power
projects in the U.S. Eleven of the nineteen projects are located in California
(17% based on invested capital at December 31, 1996), three are located in Texas
and the remainder are located in Virginia, Nevada, Georgia, Florida and
Michigan. In addition, DPS began selling excess power from Destec's facilities
as well as from other sources in June 1995.
 
    These domestic projects, which represent 49% of Destec's invested capital in
equity investments, generally operate under energy sales contracts based upon
the purchasing utility's avoided costs. Competitive initiatives in several
states, as well as federal initiatives are designed to phase-in market based
pricing. The initiatives in California propose phasing in market based pricing
by the year 2002. These initiatives are generally not yet effective and will be
the subject of considerable debate and modification. Contract prices could
change as a result of the legislative process.
 
    In February 1996, CoGen Lyondell ("CLI") and Lyondell Petrochemical Company
("LYO") formed Channelview CoGen General Partnership (the "Partnership") with
CLI as an 88% partner and LYO as a 12% partner. Houston Lighting and Power
Company ("HL&P") challenged the partnership on the basis that the structure is
actually a retail sale of electricity from CLI to LYO. A decision in HL&P's
favor was
 
                                       18
<PAGE>
rendered in Austin District Court in September 1996. Destec is pursuing an
appeal of this judgment. As a result, deliveries of power to LYO via a private
transmission line are postponed indefinitely.
 
    In July 1996, Destec completed the sale of its ownership interest in the 150
MW Blue Mountain Power project to The AES Corporation (see Note 7 of the Notes
to Consolidated Financial Statements).
 
    DPS began selling power in June 1995 and is currently marketing power
through its Western Operations and Southern Operations located in Walnut Creek,
California and Houston, Texas, respectively. DPS' Western Operations are
currently marketing power under contracts with the Port of Oakland and Pacific
Gas & Electric Company ("PG&E"). The Port of Oakland contract provides that DPS
will supply 7 MW of electricity to the Metropolitan Oakland International
Airport effective January 1, 1996 for five years. DPS' Southern Operations are
marketing capacity, energy and ancillary services to several utilities and power
marketers including Central and Southwest Services, Inc. ("CSW"), HL&P, The
Lower Colorado River Authority ("LCRA"), South Texas Electric Cooperative,
Texas-New Mexico Power Co. ("TNP"), Enron Power Marketing, Inc., National Gas &
Electric, and LG&E Power Marketing, Inc. In addition to these spot sales and
short-term contracts, DPS has a long-term contract with LCRA for capacity and
associated energy (up to 230 MW) and is nearing approval of a long-term,
full-requirements contract with another utility. DPS' Southern Operations also
markets power from the CLI and other non-utility facilities and coordinates with
other generators within the Electric Reliability Council of Texas to market
ancillary services.
 
    During 1996, Destec did not earn any revenue under the PMA for the sale of
capacity from Dow's Freeport facility due to the expiration of the two
underlying contracts in April and December 1994. The final PMA contract between
CLI and Texas Utilities Electric Company ("TUEC") expired in April 1995. In
February 1997, Dow and Destec formally terminated the PMA. Currently power
marketing activities are contracted by DPS as discussed above.
 
    Destec and DPS are attempting to negotiate new contracts for the sale of
power to industrials, utilities, municipalities, cooperatives and other
wholesale customers. No assurances, however, can be made that new contracts will
be obtained. In addition, the revenues generated from any new contracts will
likely not replace the revenue and gross margin under the agreement with Dow
relating to Dow's Freeport facility. The final negotiated price and quantity for
electricity sold under any contracts that are entered into may differ from the
previous or existing contracts. Contracts having significantly different terms
than the previous contracts substantially reduced Destec's revenues and its
gross margin in 1995.
 
INTERNATIONAL POWER
 
    Three of the international projects which were under construction at the
beginning of 1996 reached substantial completion or commercial operations during
1996. The Los Mina facility (Santo Domingo, Dominican Republic) commenced
commercial operations in May 1996, and the Indian Queens (Cornwall, United
Kingdom) and Kingston (Ontario, Canada) projects both reached substantial
completion in December 1996 and made a limited number of sales to outside
parties. In September 1996, Destec acquired an interest in the Hazelwood project
(Victoria, Australia) which was operational at the time it was purchased.
Currently, Destec is constructing the Elsta facility (Terneuzen, The
Netherlands) with completion expected in 1997. The Chiahui Power project
(Taiwan, Republic of China) is in active development, and Destec is currently in
negotiations with the Taiwan Power Company regarding development of the project.
 
    In September 1996, an indirect wholly owned subsidiary of Destec, as part of
an international consortium, purchased for $1.9 billion the 1,600 MW Hazelwood
Power Station and the adjacent Hazelwood Mine in Victoria, Australia. The
consortium formed a partnership (the "Hazelwood partnership") to own and operate
the facility. Destec holds a 20% limited partnership interest in the Hazelwood
partnership and made an original equity contribution of $176.1 million in
September 1996 (see Note 8 of the Notes to Consolidated Financial Statements).
The remainder of Destec's investment is included in the
 
                                       19
<PAGE>
project financing at the partnership level. The Hazelwood partnership is
planning a major capital expenditure program during the first three years of
ownership which may be funded from future capital contributions to refurbish two
of the eight operating units in order to maximize operating efficiencies and
upgrade environmental performance. The consortium will also seek further
investment opportunities in the Australian power industry.
 
SYNGAS
 
    The Wabash River Coal Gasification facility ("Wabash"), a joint venture of
Destec and PSI Energy, Inc. ("PSI"), with cost-sharing supplied by the U.S.
Department of Energy ("DOE"), began commercial operations in November 1995 and
is constructed to process 2,700 tons of coal per day for the net production of
262 MW of electricity. The Wabash project has an agreement with PSI which
subjects Wabash to either an operating bonus or penalty depending on the
operating rate of the facility. The maximum bonus or penalty is $7.0 million per
operating year and is calculated based on the annual syngas production and is
settled at the end of 1999. As of December 31, 1996, Destec's accrual for the
potential penalty is $2.7 million. During 1996 Destec began making significant
equipment and process improvements in order to improve the reliability and
profitability of the Wabash facility. The total cost of the improvements, which
were financed through the new operating lease in August 1996, is estimated at
$14.0 million and completion is expected in 1997.
 
    Destec's coal gasification facility (the "LGTI facility"), located near
Plaquemine, Louisiana, ceased operations in November 1995. Destec and Dow signed
an agreement in 1996 whereby the LGTI equipment and all related facilities,
except the slag pile, would be transferred to Dow. Destec has agreed to
reimburse Dow for clean-up and disposal expenses up to a maximum of
approximately $0.2 million. Destec has agreed to remove the slag pile at the
site in compliance with applicable federal, state and local legal requirements.
The cost of removal is expected to be offset by proceeds from the sale of the
slag.
 
ENERGY RESOURCES
 
    Destec is engaged in the production and development of natural gas and oil.
Total proved gas reserves have increased to over 132 billion cubic feet
equivalents ("Bcfe") as of December 31, 1996. Current daily production averages
approximately 25 million cubic feet delivered per day ("Mmcfd") from interests
in three core producing areas: 1) the Antrim Shale in the Michigan Basin, 2) the
San Juan Basin in New Mexico, and 3) the Piceance Basin in western Colorado. The
Company also owns oil and gas mineral interests in the Cotton Valley Pinnacle
Reef trend in east Texas. Destec's portfolio of properties includes interests in
157,452 gross acres and 60,217 net acres and 457 gross producing natural gas
wells. Destec has focused its acquisition and development of gas reserves in
areas that can benefit from new technology. These include the improvements in
the completion and production technology of gas wells producing from coalbed
methane reservoirs in the San Juan Basin and the Antrim Shale in Michigan and
tight gas sands in the Piceance Basin of Colorado. Destec has chosen a strategy
of being a non-operator and elects to form alliances with successful operators
in each area of interest.
 
    Destec controls, through the ownership of lignite leases or fee lands, five
lignite deposits and lignite-related properties in Freestone and Leon Counties,
Texas, comprising a total of 77,579 acres. Of the total, 9,896 acres are owned
in fee, and approximately 67,683 acres are held under lignite leases. The total
tonnage of these reserves is estimated to be approximately 640 million tons of
lignite as of December 31, 1996. See Note 22 of the Notes to Consolidated
Financial Statements for discussion of the effects the potential sale of
Destec's stock would have on Destec's lignite properties which are leased to
Dow.
 
    In November 1996, Sonat Exploration Company ("Sonat"), a wholly owned
subsidiary of Sonat, Inc., announced the completion of a Cotton Valley Pinnacle
Reef well, the Blanton #1. This well is located on an 80-acre tract (the
"Sarandos tract"), which is owned by Destec and was leased to Sonat in May 1996.
Destec believes that it owns 100% of the minerals in the Sarandos tract and that
it has a 25% royalty interest in the Blanton #1 well. In January 1997 Destec
commenced an action to quiet title to the minerals
 
                                       20
<PAGE>
and to resolve certain issues under the lease. Although Destec believes that it
will prevail in such action, there can be no assurance that this will be the
case.
 
    See Note 5 of the Notes to Consolidated Financial Statements for discussion
of purchase/sale of oil and gas properties for 1994-1996.

</TABLE>
 
- ------------------------
 
Certain amounts from previous years have been reclassified to conform to the
1996 presentation.
 
1996 COMPARED WITH 1995
 
REVENUES
 
    Destec's revenue decreased $63.6 million or 10% for 1996 as compared to
1995. This decrease resulted from a $134.9 million decrease in engineering and
operations revenue, partially offset by a $62.2 million increase in power, steam
and syngas revenue, a $5.6 million increase in energy resources revenue and a
$3.5 million increase in development revenue.
 
    The $134.9 million decrease in engineering and operations revenue resulted
primarily from lower engineering revenue recognition on the construction cost
related to the Elsta and Kingston projects in 1996, as compared to revenue
recognition on the Elsta, Kingston, Bear Mountain, Michigan Power and
 
                                       21
<PAGE>
Wabash projects in the same period of 1995. The decrease was partially offset by
engineering revenue earned in 1996 from the Hazelwood partnership under the
Engineering Services Agreement (see Note 14 of the Notes to Consolidated
Financial Statements). Operations revenue also increased in 1996 due to fees
earned prior to start-up of the Kingston project which achieved substantial
completion in December 1996, to a full year of revenue earned on the Michigan
Power project which began operations in October 1995 and to fees earned prior to
start-up of the Elsta project. In addition, Destec earned performance bonuses in
1996 from the High Sierra and Double "C" facilities.
 
    The $62.2 million increase in power, steam and syngas revenue was primarily
a result of higher power revenue due to the commencement of commercial
operations at the Los Mina facility in May 1996 and higher power and steam
revenue from the CLI and CoGen Power facilities as a result of higher gas prices
in 1996 as compared to the same period in 1995. CLI revenue was also favorably
affected by the full year of production from the sixth gas turbine which was
added in June 1995. In addition, revenue from DPS, which began selling power in
June 1995, was higher in 1996 as a result of increased sales from Southern
Operations under a contract with TNP and to various other customers through spot
sales. DPS sales from Western Operations also increased under contracts with
PG&E and the Port of Oakland in 1996. The net decrease in syngas revenue was due
to the decommissioning of the LGTI facility in November 1995, offset by
including a full year of revenues from the Wabash facility, which commenced
commercial operations in November 1995.
 
    The $5.6 million increase in energy resources revenue was due to higher gas
prices in 1996 and higher production revenue as a result of the purchase of the
Southeast Piceance gas properties in April 1996. This increase was partially
offset by receiving no production revenue in 1996 from the gas properties which
were sold in September 1995.
 
    The $3.5 million increase in development revenue resulted from the sale of
the Blue Mountain project in July 1996 (see Note 7 of the Notes to Consolidated
Financial Statements), partially offset by lower development fees earned from
the Elsta project in 1996, as compared to the development fees from the Bear
Mountain, Elsta, Kingston and Michigan Power projects earned in 1995.
 
OPERATING COSTS AND EXPENSES
 
    Destec's total operating costs and expenses decreased $94.8 million or 15%
for 1996 as compared to 1995. This decrease resulted from a $143.0 million
decrease in engineering and operations cost, a $0.6 million decrease in energy
resources cost, a $7.9 million decrease in development cost and a $0.2 million
decrease in selling, general and administrative cost. These decreases were
partially offset by a $56.9 million increase in power, steam and syngas cost.
 
    The $143.0 million decrease in engineering and operations cost resulted
primarily from lower construction costs related to the Elsta and Kingston
projects in 1996, as compared to construction costs on the Elsta, Kingston, Bear
Mountain, Michigan Power and Wabash projects in the same period of 1995.
 
    The $0.6 million decrease in energy resources cost is a result of lower
production costs associated with the gas properties which were sold in September
1995, partially offset by increased production costs from the Southeast Piceance
gas properties purchased in April 1996.
 
    The $7.9 million decrease in development cost was due to expensing costs
associated with the Bear Mountain project in 1995 which were previously
capitalized. No such expenses were incurred in 1996.
 
    The $56.9 million increase in power, steam and syngas cost was primarily a
result of higher power costs due to the commencement of commercial operations at
the Los Mina facility in May 1996. Costs at the CLI facility increased in 1996
as compared to the same period in 1995 as a result of higher gas prices and
consumption (due to addition of a sixth gas turbine in June 1995). In addition,
DPS costs were higher in 1996 as a result of increased power marketing
activities in 1996 as compared to the same period in 1995.
 
                                       22

The net decrease in syngas cost was due to the decommissioning of the LGTI
facility, partially offset by including a full year of costs from the Wabash
facility; both events occurred in November 1995.
 
EQUITY INVESTMENTS, OTHER INCOME AND TAXES
 
    Earnings from equity investments increased $7.0 million for 1996 as compared
to 1995. The increase was due primarily to contract capacity payment escalators
and to lower interest expense on the Oyster Creek project resulting from the
conversion of the term loan in July 1995 and on the California projects due to
lower interest rates and principal. Equity investments also included earnings in
1996 from the Bear Mountain and Crockett projects which became operational in
May 1995 and June 1996, respectively, and the acquisition of the operational
Hazelwood project in September 1996.
 
    The sale of gas properties in the San Juan Basin, Colorado resulted in a
before tax gain of $11.9 million in 1995. There was no such event in 1996.
 
    Other income decreased $13.2 million due primarily to a reduction in
interest income as a result of a lower average cash balance throughout 1996
compared to 1995.
 
    The effective tax rate for the year ended December 31, 1996 was 26.9% as
compared to 23.5% for the year ended December 31, 1995. The 1996 tax rate was
higher than in 1995 primarily as a result of lower non-conventional fuels source
credits in 1996.
 
1995 COMPARED WITH 1994
 
REVENUES
 
    Destec's revenue decreased $85.2 million or 12% for 1995 as compared to
1994. This decrease resulted primarily from a $147.2 million decrease in power,
steam and syngas revenue, a $7.7 million decrease in energy resources revenue
and a $8.0 million decrease in development revenue, partially offset by a $77.7
million increase in engineering and operations revenue. The decrease in power,
steam and syngas revenue resulted primarily from a decrease in PMA revenue due
to the expiration of the underlying power contracts, a decrease in syngas
revenue due to lower operating capacity at the LGTI facility in 1995 compared to
1994 and a decrease in revenue from the CLI facility as a result of the
reduction of firm capacity payments due to the expiration of the power contract
between CLI and TUEC on April 30, 1994. These decreases were partially offset by
revenue earned at the Wabash facility which commenced commercial operations in
November 1995 and by higher production at the CLI facility with the addition, in
1995, of a sixth gas turbine which provides additional capacity of approximately
120 MW. The decrease in energy resource revenue was due to lower natural gas
prices during 1995, as compared to the same period in 1994. In addition, the
1995 production revenue was lower as a result of the sale of oil and gas
properties in the third quarters ended September 30, 1995 and 1994. The decrease
in development revenue resulted from development activities on the Bear
Mountain, Elsta and Kingston projects earning less revenue than the development
activities on the Michigan Power project and settlements on the Northway and
Kingston projects during 1994. The increase in engineering and operations
revenue resulted primarily from increased engineering revenues resulting from
revenue recognition on the construction cost related to the Kingston, Elsta,
Bear Mountain, Michigan Power and Wabash projects in 1995, as compared to
revenue recognition on the Oyster Creek, Tiger Bay and Wabash projects in same
period of 1994 and increased operations revenue due to the start-up of
commercial operations in 1995 of the Tiger Bay, Bear Mountain and Michigan Power
projects on which Destec serves as operator and to fees earned prior to the
start-up of the Kingston project which achieved substantial completion in
December 1996.
 
OPERATING COSTS AND EXPENSES
 
    Destec's total operating costs and expenses increased $38.4 million or 6%
for 1995 as compared to 1994. This increase resulted primarily from a $68.7
million increase in engineering and operations cost and a $0.8 million increase
in development cost, partially offset by a $18.1 million decrease in power,
steam and
 
                                       23
<PAGE>
syngas cost, a $2.1 million decrease in energy resources cost, a $0.9 million
decrease in selling, general and administrative costs and a $10.0 million
decrease in charges related to the restructuring which occurred in 1994. The
increase in engineering and operations costs was primarily due to increased
construction activity for the Elsta, Bear Mountain, Michigan Power, Wabash and
Kingston projects in 1995, as compared to construction activity on only the
Oyster Creek, Tiger Bay and Wabash projects for the same period in 1994. The
increase in development costs was due to increased international development
activities in 1995 as compared to 1994. The decrease in power, steam and syngas
costs is primarily a result of decreased operating costs at the LGTI facility
due to a lower operating capacity in 1995, as compared to the same period in
1994. In addition, CLI refinanced and amended the operating lease at the CLI
facility which resulted in a reduction of operating costs. These decreases were
partially offset by higher costs resulting from the commencement of operations
at the Wabash facility and the recording of a decommissioning charge related to
the LGTI facility in 1995. The decrease in energy resources costs was a result
of lower production cost in 1995 compared to 1994 resulting from the sale of oil
and gas properties in the third quarters ended September 30, 1995 and 1994. The
decrease in selling, general and administrative costs resulted from the
restructuring in 1994 which reduced salary and lease costs.
 
    Earnings from equity investments increased for 1995 as compared to 1994 due
to including a full year of activity for the Hartwell and Oyster Creek projects
which began operations in April and October 1994, respectively, as well as the
start-up of commercial operations for the Tiger Bay, Bear Mountain and Michigan
Power projects in January, April and October 1995, respectively. Other income
increased due primarily to increased interest income from a higher rate of
return as a result of a shift in investment strategy from tax-exempt to taxable
investments for the year ended December 31, 1995, as compared to the same period
of 1994. The effective tax rate was 23.5% and 29.5% in the years ended December
31, 1995 and 1994, respectively. The decrease in the effective tax rate was due
primarily to the positive results of an Internal Revenue Service ("IRS") audit
concluded in 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    As of December 31, 1996, cash and cash equivalents totaled $111.4 million
and working capital totaled $210.3 million. For the year ended December 31,
1996, cash and cash equivalents increased $100.0 million. Working capital
decreased $193.3 million primarily as a result of Destec's investment in the
Hazelwood partnership (see Note 8 of the Notes to Consolidated Financial
Statements). The increase in cash and cash equivalents resulted mainly from
$56.1 million provided by Destec's operating activities, $19.7 million provided
by Destec's investing activities, which includes converting $325.8 million of
marketable securities to cash and cash equivalents, and $24.2 million provided
by Destec's financing activities. See Destec's "Statements of Consolidated Cash
Flows" for additional detail.
 
    In August 1995, CLI refinanced and amended the terms of its operating lease
agreement which resulted in a reduction to operating costs for the facility. The
financing underlying the lease expires in August 2000. The lease is an operating
lease with an initial non-cancelable term of five years ending in 2000 and an
extended term of an additional 13 years ending in 2013. The lease allows for
termination after the initial term, subject to a penalty clause. CLI is required
to remit to the lessor, in addition to basic rentals as defined, variable
rentals associated with the leveraged portion of the lease. As of December 31,
1996, the future estimated minimum lease payments under the operating lease are
approximately $212.0 million.
 
    Effective June 7, 1996, Gasification Services, Inc. ("GSI") refinanced its
operating lease agreement associated with the Wabash facility resulting in a
reduction in interest spreads and elimination of several financial covenants
associated with the original financing. The lease is backed by a Destec
guarantee which expires on April 30, 2001. At that time, Destec can refinance,
abandon and pay termination costs or purchase the facility. The future minimum
lease payments associated with the lease as of December 31, 1996 are
approximately $224.0 million. Under the Wabash lease agreement, the occurrence
of certain events ("Termination Events"), such as a change in control of Destec
(see Note 22 of the Notes to
 
                                       24
<PAGE>
Consolidated Financial Statements), will automatically terminate the lease.
According to the Wabash lease agreement, if Dow shall fail to own a majority of
outstanding shares of Destec, the Guarantor, a Termination Event will occur.
Upon the date of the occurrence of any Termination Event, the lessee shall, on
the payment date relating to the payment of partnership rent next succeeding the
Termination Event date, purchase the lessor's interest in the property from the
lessor for a purchase price equal to the lease termination payment in accordance
with purchase provisions set forth in the agreement. The lease termination
payment is $193.3 million plus accrued interest from the date of last lease
payment.
 
    At December 31, 1996 and 1995, respectively, Destec had outstanding
irrevocable letters of credit from banks totaling $35.4 million and $31.0
million. These letters of credit are pledged to support certain Destec equity
commitments and other development activities. As of December 31, 1996 Destec has
a corporate guarantee associated with an equity contribution to the Elsta
project of approximately $39.6 million which is expected to be made in 1998. The
Hazelwood partnership is planning a major capital expenditure program during the
first three years of ownership which may be funded from future capital
contributions to refurbish two of the eight operating units in order to maximize
operating efficiencies and upgrade environmental performance.
 
    Destec contracted in 1993 to design, engineer, build and operate a
cogeneration facility in Polk County, Florida to be owned by a Delaware limited
partnership (the "Tiger Bay project") in which Destec has an approximate 50%
non-controlling equity interest. Destec has a commitment to loan up to an
additional $10.0 million (subordinated to the partnership's senior lenders) to
the Tiger Bay project based on the project steam host's ability to contractually
perform. In December 1993, Destec entered into a twenty year firm transportation
agreement with Florida Gas Transmission to maintain firm gas transportation
capacity which became effective in March 1995. Destec is required to pay
approximately $3.5 million per year over the contract life to maintain
transportation capacity. During 1996, Destec sold the excess capacity which the
Tiger Bay project was unable to utilize. Because the current market rate for
natural gas transportation capacity was less than Destec's contracted cost, a
resulting net fuel expense of $2.9 million was incurred in 1996.
 
    In January 1997, Tiger Bay Limited Partnership, in which Destec holds an
equity interest of approximately 50%, executed an agreement for the sale of the
Tiger Bay cogeneration facility, located in Fort Meade, Florida to a wholly
owned subsidiary of Florida Power Corporation for $445.0 million. Destec's
estimated share of the proceeds after repayment of partnership debt and the net
settlement of other partnership obligations is anticipated to be approximately
$140.0 million. The sale is subject to certain conditions, including regulatory
approvals and the sale of Destec. See Note 22 of the Notes to Consolidated
Financial Statements for additional discussion.
 
    As a result of operational defects in the administration of the Destec
Energy, Inc. Retirement and Savings Plan since 1991, Destec filed a Voluntary
Compliance Report ("VCR") with the IRS. If the VCR application is approved by
the IRS, Destec will make a contribution to the Plan of approximately $4.7
million (before tax effect) including accrued interest. Destec's management
believes that adequate reserves are provided as of December 31, 1996 for this
potential liability.
 
    Since 1992, the Board of Directors authorized the repurchase of up to $95.0
million of Destec's common stock through 1999. As of December 31, 1996, Destec
had repurchased 6,816,549 and reissued 645,809 shares of common stock
repurchased under these programs.
 
    In August 1996, Destec arranged non-recourse financing for the 140 MW Indian
Queens facility located in Cornwall, United Kingdom. The project financing,
which consists of a $56.6 million construction facility and $39.8 million in
term facility and other debt instruments, was arranged and underwritten by
Barclays Bank PLC. Through December 31, 1996 Destec has recorded advances under
the construction facility of $53.8 million in PROJECT FINANCING DEBT. The credit
agreement divides the facility into two tranches which carry interest at LIBOR
plus variable margins. The conversion of the construction loan to term is
expected to occur in early 1997. The term loan is collateralized by the
project's assets and matures over a
 
                                       25
<PAGE>
period of 17 years. Interest costs of approximately $1.0 million incurred during
the construction of the facility were capitalized as of December 31, 1996. The
interest rates in effect as of December 31, 1996 were 6.52% on $24.0 million and
7.27% on $29.8 million. Under the terms of the credit agreement, the
unconsolidated financial statements of the Indian Queens project are subject to
various coverage ratios; however, because these are at the project level,
management does not believe they will affect Destec's ability to conduct
business.
 
    Destec and Dow have extended credit to each other up to $350.0 million from
time to time under the Destec/Dow Credit Agreements. The agreements expired on
December 31, 1996, and management does not expect renewal at this time. At
December 31, 1995, cash equivalents included $4.4 million of cash advances to
Dow. Due to the expiration of the credit agreements no amounts were included in
cash equivalents at December 31, 1996. There were no outstanding borrowings from
Dow at December 31, 1996 and 1995.
 
    Covenants contained in various agreements relating to certain of Dow's
indebtedness prohibit Dow from allowing Destec, subject to certain exceptions,
to encumber or otherwise pledge as security any of its properties or assets or
the capital stock of any of Destec's subsidiaries. In addition, Dow may not
permit Destec to incur indebtedness to the extent such occurrence would cause
Dow indebtedness on a consolidated basis to exceed 60% of Dow's consolidated
capitalization. As of December 31, 1996 Dow's indebtedness on a consolidated
basis was approximately 29% of consolidated capitalization. Dow's debt
instruments also restrict the ability of Dow and its subsidiaries to engage in
certain sale and lease-back transactions involving facilities which are material
to the business conducted by Dow and its subsidiaries located in the United
States taken as a whole. Destec's management believes that neither these
restrictions nor the expiration of the credit agreements discussed above will
significantly affect Destec's ability to conduct its business.
 
    Management believes that current cash and cash equivalents and operating
cash flows will be sufficient to fund Destec's working capital, additions to
fixed assets and investments in projects.

              FOR THE YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
             (IN THOUSANDS OF DOLLARS, UNLESS OTHERWISE INDICATED)
 
1. ORGANIZATION AND BASIS OF PRESENTATION
 
    Destec Energy, Inc. and its wholly owned subsidiaries ("Destec"), a Delaware
corporation and a majority owned subsidiary of The Dow Chemical Company ("Dow"),
was incorporated in May 1989. Prior to Destec's initial public offering (the
"Offering") in 1991, Dow transferred to Destec certain energy related operations
and associated assets and liabilities in exchange for all Destec's issued and
outstanding Common Stock.
 
    Since 1992, the Destec Board of Directors (the "Board") has authorized the
repurchase of up to $95,000 of Destec's common stock through 1999. As of
December 31, 1996, Destec had repurchased 6,816,549 shares and reissued 645,809
shares of common stock repurchased under these programs.
 
    In connection with the execution of the Tax Sharing Agreement (the "Tax
Agreement") discussed in Note 2, Dow will have a continuous, cumulative option
to purchase from Destec at current market prices such number of shares of common
stock of Destec as Dow determines necessary to allow Dow to continue to include
Destec in Dow's consolidated federal income tax return.
 
    Destec is an independent power producer and marketer of electricity, thermal
energy and syngas for sale to electric utilities, Dow and other energy-intensive
industries. Revenues and costs associated with the sale of power, thermal
energy, syngas, energy resources (oil, gas and lignite) and associated with the
marketing of power through Destec Power Services, Inc. ("DPS"), a wholly owned
subsidiary of Destec, and the Power Marketing Agreement ("PMA") (through the
final contract expiration on April 30, 1995) are included as "Power, steam,
syngas and energy resources" revenues and operating costs in the accompanying
statements of consolidated income. Destec also designs, develops, operates, and
performs business management services for its cogeneration and syngas facilities
in the U.S. and abroad. Revenue and costs associated with the fees earned in
connection with these activities are included as "Development, engineering and
operations" revenues and operating costs in the accompanying statements of
consolidated income.
 
    See Note 22 for discussion of the proposed merger of Destec with a wholly
owned subsidiary of NGC Corporation ("NGC").
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES
 
    PRINCIPLES OF CONSOLIDATION--The accompanying consolidated financial
statements include the assets, liabilities, revenue and expenses of all majority
owned subsidiaries. Investments in partnerships with ownership interests of 50%
or less and which Destec does not control are accounted for using the equity
method. All significant balances and transactions within the consolidated group
have been eliminated in consolidation.
 
    REVENUE RECOGNITION--Revenues for the sale or marketing of electricity,
steam and syngas are recorded based upon output or product delivered as
specified under contract terms. Revenues from performance bonuses are recognized
when specified contractual targets are achieved. Energy resources revenues (oil,
gas and lignite) are recognized as production from these resources occurs or as
earned under contract.
 
    Revenues resulting from long-term engineering and project construction
contracts are recognized using the percentage-of-completion accounting method.
The percentage of revenue recognized on each

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
              FOR THE YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
             (IN THOUSANDS OF DOLLARS, UNLESS OTHERWISE INDICATED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES (CONTINUED)
contract is based on the most recent cost estimate available. Revisions of
estimates are reflected in the year in which the facts necessitating the
revision become known. When the current contract estimate indicates a loss, a
provision is made for the total anticipated loss.
 
    Profits from engineering and construction contracts and development fees
received from partnerships in which Destec holds an equity interest are deferred
to the extent of Destec's ownership interest in the partnership. The deferred
income is amortized on a straight-line basis over the partnership debt term used
to finance the facility, except where the equity method of accounting permits
earlier recognition.
 
    USE OF ESTIMATES IN FINANCIAL STATEMENT PREPARATION--The preparation of
financial statements in conformity with generally accepted accounting principles
requires estimates and assumptions that affect the reported amounts of assets
and liabilities and disclosure of contingent assets and liabilities at the date
of the financial statements and the reported amounts of revenue and expenses
during the reporting period. Destec's financial statements include amounts that
are based on management's best estimates and judgments. Actual results could
differ from those estimates.
 
    CASH AND CASH EQUIVALENTS--Cash and cash equivalents include time deposits
and readily marketable securities with an original maturity of three months or
less. Until the expiration of the Destec Credit Agreement on December 31, 1996,
Destec periodically loaned excess cash to Dow. This agreement required Dow, upon
60 days written notice from Destec, to repay all or any portion of the then
outstanding loan balance.
 
    MARKETABLE SECURITIES--Effective January 1, 1995 the Company adopted SFAS
No. 115, "ACCOUNTING FOR CERTAIN INVESTMENTS IN DEBT AND EQUITY SECURITIES." All
of Destec's marketable securities are classified as "available for sale," and
accordingly, are reflected in the Consolidated Balance Sheets at fair market
value, with the aggregate unrealized gains or losses included as a component of
stockholders' equity. Adoption of SFAS No. 115 had no effect on reported
earnings. Cost for determining gains and losses on sales of marketable
securities is determined on the FIFO method.
 
    RECOVERABLE PROJECT COSTS--Destec capitalizes certain project costs incurred
to procure equipment, to connect with utility transmission lines, and certain
other costs, once management determines it is probable these costs are
recoverable, until contracts for financing and sale are executed. If the
necessary contracts are not obtained and the costs incurred are not recoverable
through other projects or sale, the related costs are charged to expense. These
costs are classified as current if they are expected to be recovered in the next
12 months.
 
    PROPERTY, GOODWILL AND DEPRECIATION, DEPLETION AND AMORTIZATION --Buildings
and equipment are carried at cost less accumulated depreciation. Depreciation is
based on the estimated service lives for depreciable assets and is generally
provided using the double declining balance method for all subsidiaries except
for Destec Holdings, Inc. and its subsidiaries which use the straight line
depreciation method. Estimated service lives range from three to thirty-two
years.
 
    Cost associated with acquiring and developing lignite properties are
capitalized as incurred. Depletion and amortization of lignite properties are
recorded using the units-of-production method based on an estimate of proved
reserve quantities to be mined in the future.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
              FOR THE YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
             (IN THOUSANDS OF DOLLARS, UNLESS OTHERWISE INDICATED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES (CONTINUED)
    The excess of the cost of investments in subsidiaries over the fair value of
assets acquired and liabilities assumed is shown as goodwill, which is amortized
over the estimated useful life of 40 years.
 
    The Company evaluates long-lived assets, including goodwill, for impairment
based on the recoverability of the asset's carrying amount. When it is probable
that the undiscounted future cash flows will not be sufficient to recover the
asset's carrying amount, the asset is written down to its fair value. Destec
adopted SFAS 121 "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of" on January 1, 1996. The adoption of this
standard had no material impact on Destec's financial position or results from
operations.
 
    Costs incurred to acquire or retain oil and gas properties, owned in fee or
under lease, are capitalized. Destec grants leases to exploration and production
companies, generally retaining royalty interests. Costs to acquire mineral
interests in oil and gas properties and to drill and equip developmental wells
are capitalized. Costs associated with oil and gas properties are amortized
using the units-of-production method based upon estimates of proved reserves.
The Company evaluates the recoverability of its oil and gas properties by
determining that the undiscounted future cash flows on an aggregated basis are
sufficient to recover the net carrying value.
 
    Fully depreciated assets are retained in property and accumulated
depreciation accounts until they are removed from service. In the case of
disposals, assets and related depreciation are removed from the accounts and the
net amount, less proceeds from disposal, is charged or credited to income.
 
    MAJOR MAINTENANCE--A major maintenance and repair reserve is recorded based
on Destec's scheduled maintenance plans for cogeneration and syngas facilities
operated or owned by Destec. This liability is classified as current if the
maintenance is expected to be incurred in the next 12 month period. Other
maintenance and repairs are charged to expense as incurred (see Notes 9 and 10).
 
    RESEARCH EXPENSE--All expenses associated with research and development are
expensed in the year incurred. Research expenses were $213, $808 and $864 in
1996, 1995 and 1994, respectively.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS--The Company calculates the fair value
of financial instruments and includes this additional information in Note 3.
 
    TAXES ON INCOME--Destec recognizes deferred tax assets and liabilities for
the expected future tax consequences of temporary differences between the book
carrying amounts and the tax basis of all balance sheet assets and liabilities.
These temporary differences are calculated using tax rates currently in effect.
 
    Effective June 6, 1996, Destec is included in the consolidated federal
income tax return of Dow, as Dow's ownership increased above 80%. Destec and Dow
executed the Tax Agreement which requires Destec to calculate federal and state
income taxes on a stand-alone basis. The Tax Agreement allows Destec to reduce
its federal stand-alone tax liability by certain non-conventional fuels tax
credits which have been utilized in Dow's consolidated return, even where such
credits would not be otherwise currently usable by Destec. See Note 22 for
discussion of the effects the proposed merger of Destec with a wholly owned
subsidiary of NGC would have on the Tax Agreement.
 
    NET INCOME PER SHARE--Net income per share is computed by dividing net
income by the weighted average number of shares outstanding during the year. The
shares described in Note 17 relating to the

2. SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES (CONTINUED)
Destec Stock Plans are not considered in the net income per share calculation.
If these shares were to be included, they would not have had a material effect
on net income per share for the years ended December 31, 1996, 1995 and 1994,
respectively.
 
    ACCOUNTING FOR STOCK BASED COMPENSATION--The Financial Accounting Standards
Board issued SFAS No. 123, "Accounting for Stock-Based Compensation," in October
1995. Destec adopted SFAS No. 123, effective January 1, 1996, and continues to
apply its current accounting policy under Accounting Principles Board ("APB")
Opinion No. 25 and has included additional footnote disclosures for the
pro-forma impact on net income and earnings per share of the application of the
fair value based method of accounting (see Note 17).
 
    FOREIGN CURRENCY TRANSLATION--Assets and liabilities of certain foreign
subsidiaries are translated into U.S. dollars at current exchange rates in
effect at the end of the fiscal period, and related revenues and expenses are
translated at average exchange rates that prevailed during the period. Resulting
translation adjustments, as well as adjustments for intercompany transactions
which are long-term in nature are shown in stockholder's equity in CUMULATIVE
TRANSLATION ADJUSTMENTS. The foreign currency gain/loss on the remeasurement of
short-term foreign currency transactions of certain U.S. subsidiaries are
included in net income. The net CUMULATIVE TRANSLATION ADJUSTMENTS includes a
foreign currency gain of $3,917 and a loss of $191 for the year ended December
31, 1996. Foreign currency transaction gains of $3,841 were related to the
remeasurement of long-term intercompany loans. No adjustments were recorded for
the year ended December 31, 1995.
 
    RECLASSIFICATIONS--Certain amounts from previous years have been
reclassified to conform to the 1996 presentation.
 
3. FINANCIAL INSTRUMENTS

3. FINANCIAL INSTRUMENTS (CONTINUED)
    In February 1994, Destec purchased a series of Dutch Guilder put options in
order to hedge its projected foreign currency risk associated with the
engineering contract for the Elsta project. The total premium cost for this
program was $6,450. The Dutch Guilder put options were purchased from Dow,
acting as an intermediary who in turn purchased the options from a bank. As of
December 31, 1996, no options have been exercised as put option prices have been
above Dutch Guilder exchange rates. These options have varying expiration dates
through August 1997; however, due to changes in foreign currency markets, the
options have no market value. As a result, the entire cost of this program was
expensed in 1994 as part of the project cost.
 
4. ENGINEERING AND CONSTRUCTION CONTRACTS
 
    The following table reflects the amounts related to uncompleted engineering
and construction contracts:

$38,768 and $7,749 related to foreign projects as of December 31, 1996 and 1995,
respectively. Billings in excess of costs and estimated earnings--affiliates
includes $41,014 related to the Elsta project as of December 31, 1995.
 
    Certain amounts are due, but not paid by Destec until the related outside
vendors have completed their obligations pursuant to contract retainage
provisions. The amounts retained under such contract provisions were $14,234 and
$11,291 at December 31, 1996 and 1995, respectively, and are expected to be paid
within one year.
 
    In February 1996, CoGen Lyondell, Inc. ("CLI") and Lyondell Petrochemical
Company ("LYO") formed Channelview CoGen General Partnership (the "Partnership")
with CLI as an 88% partner and LYO as a 12% partner. Under the partnership
agreement, power generated at the CLI facility would be

distributed to the partners, in proportion to their partnership percentages,
under the self generation exception of the Texas Public Utility Regulatory Act.
Included in COSTS AND ESTIMATED EARNINGS IN EXCESS OF BILLINGS--AFFILIATES at
December 31, 1996 is $3,873 related to the construction of a transmission line
between the CLI facility and the LYO facility. LYO entered into a note
receivable agreement with Destec to finance the construction. Note payments are
to begin once the construction is completed and accepted by LYO. Houston
Lighting and Power Company ("HL&P") challenged the partnership on the basis that
the structure is actually a retail sale of electricity from CLI to LYO. A
decision in HL&P's favor was rendered in Austin District Court in September
1996. Destec is pursuing an appeal of this judgement. As a result, deliveries of
power to LYO via the private transmission line are postponed indefinitely. If
delivery of the power is not approved by the courts and the line cannot be
utilized, LYO would be obligated to pay 50% of the note receivable, although
once accepted by LYO, title to the transmission line would remain with LYO.

    During 1995 and 1996, Destec constructed the Los Mina facility, located in
the Dominican Republic, which became operational in May 1996, and the Indian
Queens facility, located in the United Kingdom, which reached substantial
completion in December 1996. Total construction cost for the Los Mina and Indian
Queens facilities, which are wholly owned by Destec, was $130,720 through
December 31, 1996 (see Note 11).
 
    In 1996, Destec acquired an undivided 45% interest in proved producing
natural gas properties and related undeveloped leasehold acreage and gas
pipeline system in northwest Colorado from Snyder Oil Corporation ("SOCO") for
approximately $22,000. The total proved reserves for Destec's interest in the
properties are estimated to be approximately 42 billion cubic feet. SOCO will
retain a majority working interest in the properties and will continue to
operate the wells. Destec has entered into a joint venture agreement with SOCO
covering the long-term development of the underlying properties and associated
gas pipeline.
 
    In 1995 and 1994, Destec sold a group of non-conventional gas properties in
the San Juan Basin, Colorado, and a group of non-strategic oil and gas
properties in the Texas and Louisiana Gulf Coast areas,

              FOR THE YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
             (IN THOUSANDS OF DOLLARS, UNLESS OTHERWISE INDICATED)
 
5. PROPERTY (CONTINUED)
respectively. The sale of these properties resulted in pre-tax gains of $11,890
and $17,196 in 1995 and 1994, respectively. Included in Destec's lignite
properties are $6,526 of costs for each of 1996 and 1995, representing
properties currently being mined for which Destec is receiving royalty payments.
 
6. LEASE RECEIVABLE FROM DOW
 
    Destec leases certain lignite properties to Dow under a lease which requires
annual rental payments through the year 2025. Dow pays an annual amount equal to
ten percent of the sum of (a) Destec's book value of the properties as of
December 29, 1989 plus (b) the cumulative advance royalties attributable to such
properties as of December 29, 1989 or approximately $4,400 per year. All
properties under this lease agreement not previously purchased by Dow will be
purchased on December 31, 2025 in exchange for a payment equal to the
properties' then book value. In addition, Dow has an option to purchase all of
Destec's interest in any one or more of the properties at a price equal to
Destec's book value of the properties as of the year end preceding the year in
which such option is exercised.
 
    Destec has an agreement with Dow to manage, market and maintain certain
lignite-containing properties, including the above described leased properties.
Dow pays Destec a fee of $250 per year (adjusted annually for inflation) and all
out-of-pocket expenses. The term of this agreement is the same as the above
described lease agreement and may be terminated by either party upon one year's
notice. The amounts under this agreement, which are included as a reduction of
selling, general and administrative costs, related to Dow were $302, $295, and
$287 for 1996, 1995 and 1994, respectively.
 
    See Note 22 for discussion of the effects the proposed merger of Destec with
a wholly owned subsidiary of NGC would have on Destec's lignite properties lease
and related management agreement with Dow.
 
7. SALE OF BLUE MOUNTAIN
 
    In July 1996, Destec agreed to sell its ownership interest in the 150 MW
Blue Mountain Power Project to The AES Corporation. The sale of this project,
which was included in development revenue, had a positive after tax effect of
approximately $6,900 (considering an effective tax rate of 26.9%) or $0.12 per
share for the year ended December 31, 1996.
 
8. EQUITY INVESTMENTS
 
    Destec holds non-controlling general and limited equity interests in twenty
partnerships which were formed to build, own and operate cogeneration
facilities. The lenders to these partnerships have recourse only against the
projects and the income and revenues therefrom and thus, the partnerships' debt
obligations are non-recourse to Destec. Destec's effective equity interest in
these partnerships ranges from 8% to 50%.
 
    Seventeen of Destec's twenty projects accounted for under the equity method
are concentrated in the U.S. (49% based on invested capital at December 31,
1996). Additionally, eleven projects are located in California (17% based on
invested capital at December 31, 1996). These domestic projects generally
operate under energy sales contracts based upon the purchasing utility's avoided
cost. Competitive initiatives in several states, as well as federal initiatives
are designed to phase-in market based pricing. The

initiatives in California propose phasing in market based pricing by the year
2002. These initiatives are generally not yet effective and will be the subject
of considerable debate and modification; however, changes in contract prices
could result from the legislative process.
 
    Destec has been engaged to perform project development, engineering,
construction, operations and maintenance and business management services
related to certain of these partnerships and has recognized revenues of
$324,116, $455,517, and $385,853 in 1996, 1995 and 1994, respectively. Assets
and liabilities associated with the performance of these services and the
advancement of funds are included in the balance sheet captions labeled
"Affiliates."
 
    In September 1996, an indirect wholly owned subsidiary of Destec, as part of
an international consortium, purchased for $1,900,000 the 1,600 MW Hazelwood
Power Station and the adjacent Hazelwood Mine in Victoria, Australia. The
consortium formed a partnership (the "Hazelwood partnership") to own and operate
the Hazelwood facility. Destec holds a 20% limited partnership interest in the
Hazelwood partnership and made an original equity contribution of $176,104 in
September 1996. A wholly owned subsidiary of Destec entered into a separate
agreement with National Power PLC, another member of the international
consortium, in September 1996, which entitles Destec to receive approximately
$4,000 for each of the years ended December 31, 1997, 1998 and 1999. The total
amount of approximately $12,000 is recorded in NOTE RECEIVABLE--AFFILIATES,
LONG-TERM/SHORT-TERM as of December 31, 1996 and reduces Destec's original
equity contribution to $164,104. The remainder of Destec's investment is
included in the project financing at the partnership level. The Hazelwood
partnership is planning a major capital expenditure program which may be funded
from future capital contributions to refurbish two of the eight operating units
in order to maximize operating efficiencies and upgrade environmental
performance.
 
    Unaudited pro forma net income and net income per share of Destec, as if the
acquisition had occurred at the beginning of the years and after giving effect
to certain pro forma adjustments related to the acquisition, were approximately
$38,990 and $0.68 and $29,492 and $0.50 for 1996 and 1995, respectively. Pro
forma revenue was $574,146 and $636,288 in 1996 and 1995, respectively. Such pro
forma amounts are not necessarily indicative of what the actual consolidated
results of operations might have been if the acquisition had been effective at
the beginning of 1996 or 1995.
 
    See Note 14 for discussion of the engineering services agreement with the
Hazelwood partnership.

              FOR THE YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
             (IN THOUSANDS OF DOLLARS, UNLESS OTHERWISE INDICATED)
 
11. PROJECT FINANCING DEBT
 
    In August 1996, Destec arranged non-recourse financing for the 140 MW Indian
Queens facility located in Cornwall, United Kingdom. The project financing,
which consists of a $56,562 construction facility and $39,850 in term facility
and other debt instruments, was arranged and underwritten by Barclays Bank PLC.
Through December 31, 1996 Destec has recorded advances under the construction
facility of $53,820 in PROJECT FINANCING DEBT. The credit agreement divides the
facility into two tranches which carry interest at LIBOR plus variable margins.
The conversion of the construction loan to term is expected to occur in early
1997. The term loan is collateralized by the project's assets and matures over a
period of 17 years. Under the terms of the credit agreement, the unconsolidated
financial statements of the Indian Queens project are subject to various
coverage ratios. Interest costs of approximately $1,000 incurred during the
construction of the facility were capitalized as of December 31, 1996. The
interest rates in effect as of December 31, 1996 were 6.52% on $23,996 and 7.27%
on $29,824.
 
12. SYNGAS
 
    In 1992, Destec entered into an agreement with the U.S. Department of Energy
("DOE") and PSI Energy, Inc. ("PSI") for the design, construction and operation
of a syngas facility, the Wabash River Coal Gasification Repowering project
("Wabash facility"). The Wabash facility, located in Indiana, began commercial
operations in November 1995. The capacity of the facility is approximately 262
MW. Destec will provide coal gasification services for PSI under a 25 year
contract. Effective June 1996, Destec refinanced its operating lease agreement
associated with the Wabash facility to include certain improvements made to the
facility. Under the terms of the gasification services agreement with PSI,
Wabash is subject to either an operating bonus or penalty depending on the
operating rate of the facility. The maximum bonus or penalty is $7,000 per
operating year and is calculated based on the annual average syngas production.
Destec's accrual for this potential penalty was $2,722 and $1,741 as of December
31, 1996 and 1995, respectively. During 1996, Destec began making significant
equipment and process improvements in order to improve the reliability and
profitability of the Wabash facility. The total cost of the improvements is
estimated at $14,000 and completion is expected in 1997.
 
    Under the terms of the DOE Agreement, the DOE paid $161,000 of the
construction costs and will pay 50% of certain operating costs during the first
three years of operation. These reimbursements, which are netted in operating
costs were $13,719 and $3,230 in 1996 and 1995, respectively.
 
    Pursuant to a 1985 settlement agreement between Dow and a competitor, Dow
made a payment of $2,250 for the future use of coal gasification technology by
Dow and or its successors. In order for Destec, as Dow's successor, to receive
the benefit of this payment in connection with Wabash, Dow transferred the
benefit of this $2,250 payment to Destec. Thus, Destec received a $2,250 asset
from Dow and recorded it as additional-paid-in-capital. An additional $1,250
obligation related to the foregoing was accrued in 1995 and capitalized as part
of the project by Destec as the successor to the coal gasification business of
Dow after completion and start-up of this facility in November 1995.

             (IN THOUSANDS OF DOLLARS, UNLESS OTHERWISE INDICATED)
 
12. SYNGAS (CONTINUED)
 
    In connection with an agreement with the U.S. Department of Treasury, Destec
received certain guaranteed payments ("Guaranteed Payments") for the sale of
syngas to Dow that was produced at Destec's coal gasification facility (the
"LGTI facility"), located near Plaquemine, Louisiana. During 1995, Destec earned
$63,014, leaving a balance of $59 from the cumulative Guaranteed Payments of
$584,500. The remaining balance will not be earned because it was not economical
to restart the plant after the outage in November 1995. The LGTI facility was
fully depreciated as of September 1995. Destec and Dow signed an agreement in
1996 whereby the LGTI equipment and all related facilities, except the slag
pile, would be transferred to Dow. Destec has agreed to reimburse Dow for
clean-up and disposal expenses up to a maximum of approximately $250. Destec has
agreed to remove the slag pile at the site in compliance with applicable
federal, state and local legal requirements. The cost of removal is expected to
be offset by proceeds from the sale of the slag.
 
13. INCOME TAXES
 
    The provision for income taxes consisted of the following:

    The change in valuation allowance during 1995 was a net increase of $2,421
due primarily to foreign tax losses which were not likely to be realizable at
that time. The change in valuation allowance during 1996 was a net decrease of
$549 due to investment tax credits utilized of $908 and foreign tax losses of
$359 which do no appear realizable at this time. During 1996, $908 of investment
tax credit carryforwards were utilized to reduce taxes payable and were
reflected as a reduction of goodwill. The valuation allowance includes
approximately $1,700 of investment tax credit carryforwards expiring in 2003
which may not be realized. These carryforwards are limited to use by the
subsidiary in which they were generated. See Note 22 for discussion of the
effects the proposed merger of Destec with a wholly owned subsidiary of NGC
would have on the Tax Agreement between Dow and Destec.

              FOR THE YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
             (IN THOUSANDS OF DOLLARS, UNLESS OTHERWISE INDICATED)
 
14. RELATED PARTY TRANSACTIONS (CONTINUED)
    The transactions which resulted in these balances are described as follows:
 
    Destec had entered into a PMA with Dow whereby Destec provided
administrative, business management and marketing services with respect to a
portion of the electricity generated at Dow's Freeport, Texas cogeneration
facilities and sold under contracts to the local utilities. The final contract
related to this agreement expired on April 30, 1995. For such services, Dow paid
Destec an amount based on a formula specified in the PMA. The resulting revenue
recorded and collected was $3,276 and $125,209 for the years ended December 31,
1995 and 1994, respectively.
 
    The LGTI facility, which ceased operations in November 1995, provided fuel
to a Dow plant pursuant to a long-term fuel supply contract. Revenues from such
sales aggregated $7,611 and $13,661 for the years ended December 31, 1995 and
1994, respectively. No revenues for such sales were earned for the year ended
December 31, 1996. Destec and Dow signed an agreement in 1996 under which the
LGTI equipment and all related facilities, except the slag pile, were
transferred to Dow. Destec has agreed to reimburse Dow for clean-up and disposal
expenses up to a maximum of $250. Destec has agreed to remove the slag pile at
the site in compliance with applicable federal, state and local legal
requirements. The cost of removal is expected to be offset by proceeds from the
sale of the slag (see Note 12).
 
    LGTI purchased from Dow certain materials and services (including research
and development) necessary for the operation of its facility pursuant to service
agreements. In addition, Dow performed the purchasing of all operating
activities of the LGTI facility. Costs incurred related to these services
aggregated $13,509 and $19,271 for the years ended December 31, 1995 and 1994,
respectively. During 1996, costs of $1,176 were incurred during the site
clean-up of the LGTI facility. Amounts of $523 and $3,274 relating to these
services were included in ACCOUNTS PAYABLE--DOW at December 31, 1996 and 1995,
respectively.
 
    Destec and Dow have entered into an amended service agreement whereby
certain administrative services are provided to Destec at a fee of $122 per
calendar quarter. In the opinion of management, the service agreement is based
on reasonable estimates of the costs of such services.
 
    Destec and Dow have extended credit to each other up to $350,000 from time
to time under the Destec/Dow Credit Agreements. The agreements expired on
December 31, 1996, and management does not expect renewal at this time. At
December 31, 1995, cash equivalents included $4,422 of cash advances to Dow. Due
to the expiration of the agreements no amounts were included in cash equivalents
at December 31, 1996. Interest due on Destec advances to Dow of $122 and $566 is
included in ACCOUNTS RECEIVABLE--DOW at December 31, 1996 and 1995,
respectively. There were no outstanding borrowings from Dow at December 31, 1996
and 1995.
 
    Certain personnel, occupancy and engineering services are performed by both
Dow and Destec. The net amounts of $10,372 and $9,395 related to such services
were included in ACCOUNTS RECEIVABLE/ACCOUNTS PAYABLE--DOW at December 31, 1996
and 1995, respectively.
 
    See Note 6 for discussion of lease receivable from Dow.
 
    In 1993, Destec signed an agreement to develop the 405 MW Elsta facility in
the Netherlands to provide steam and electricity to Dow's Terneuzen facility as
well as electricity to the local distribution network. The project is expected
to commence commercial operations in 1997.

14. RELATED PARTY TRANSACTIONS (CONTINUED)
    The Oyster Creek facility, in which Destec owns a 50% non-controlling
interest, commenced commercial operations in October 1994. The 424 MW facility
provides 369 MW of electricity and 1.1 million pounds per hour of process steam
to Dow who also operates and maintains the facility. See Note 22 for discussion
of the effects the proposed merger of Destec with a wholly owned subsidiary of
NGC would have on the Oyster Creek facility.
 
    In October 1995, the Michigan Power project, in which Destec owns a 50%
non-controlling interest, commenced commercial operations. The 123 MW facility,
located in Ludington, Michigan, provides Dow with 320,000 pounds per hour of
process steam.
 
    Dow and Destec entered into a registration rights agreement pursuant to the
Offering in which Dow has been granted certain demand and piggyback registration
rights with respect to the common stock of Destec owned by Dow as of such date
or acquired thereafter. Destec agrees to indemnify Dow for certain liabilities,
including liabilities under the Securities Act of 1933, in connection with such
registration.
 
    Dow assigned to Destec certain patents, pending patent applications,
inventions, discoveries and information pertaining to coal gasification and
lignite beneficiation pursuant to the Offering. Dow retained a royalty-free
world-wide license to use this technology in Dow facilities for chemical
production. Dow and Destec have entered into (i) a First Amendment to Research
and Development Agreement, effective December 31, 1996 and (ii) a First
Amendment to Assignment Agreement, effective as of December 15, 1996. Pursuant
to the Research and Development Agreement, as amended, Destec engaged Dow to
provide certain research and development services with respect to intellectual
property relating to the gasification of carbonaceous materials and to lignite
beneficiation.
 
    Covenants contained in various agreements relating to certain of Dow's
indebtedness prohibit Dow from allowing Destec, subject to certain exceptions,
to encumber or otherwise pledge as security any of its properties or assets or
the capital stock of any of Destec's subsidiaries. In addition, Dow may not
permit Destec to incur indebtedness to the extent such occurrence would cause
Dow indebtedness on a consolidated basis to exceed 60% of Dow's consolidated
capitalization. As of December 31, 1996, Dow's indebtedness on a consolidated
basis was approximately 29% of consolidated capitalization. Dow's debt
instruments also restrict the ability of Dow and its subsidiaries to engage in
certain sale and lease-back transactions involving facilities which are material
to the business conducted by Dow and its subsidiaries located in the United
States taken as a whole. Destec's management believes that these restrictions
will not significantly affect Destec's ability to conduct its business.
 
    In September 1996, in conjunction with Destec's acquisition of a 20%
interest in the Hazelwood partnership (see Note 8), Destec entered into an
engineering services agreement with the Hazelwood partnership. This agreement
encompasses engineering consultation related to the capital improvement program
at the Hazelwood facility.
 
15. LEASE COMMITMENTS
 
    Effective June 7, 1996, Gasification Services, Inc. ("GSI") refinanced its
operating lease agreement associated with the Wabash facility for a term of 5
years resulting in a reduction in interest spreads and elimination of several
financial covenants associated with the original financing. The future minimum
lease payments associated with the lease as of December 31, 1996 are
approximately $224,000. Destec has

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

15. LEASE COMMITMENTS (CONTINUED)
guaranteed GSI's performance pursuant to this new lease agreement. Under the
Wabash lease agreement, the occurrence of certain events ("Termination Events"),
such as a change in control of Destec (see Note 22), will automatically
terminate the lease. According to the Wabash lease agreement, if Dow shall fail
to own a majority of outstanding shares of Destec, the Guarantor, a Termination
Event will occur. Upon the date of the occurrence of any Termination Event, the
lessee shall, on the payment date relating to the payment of partnership rent
next succeeding the Termination Event date, purchase the lessor's interest in
the property from the lessor for a purchase price equal to the lease termination
payment in accordance with purchase provisions set forth in the agreement. The
lease termination payment is $193,300 plus accrued interest from the date of
last lease payment.
 
    Destec also has an operating lease for the CLI facility with future
estimated minimum lease payments as of December 31, 1996 of approximately
$212,000. The lease agreement is an operating lease with an initial
non-cancelable term of 5 years ending in 2000 and an extended term of an
additional 13 years ending in 2013. The lease allows for termination after the
initial term, subject to a penalty clause. CLI is required to remit to the
lessor, in addition to basic rentals as defined, variable rentals associated
with the leveraged portion of the lease. Dow has guaranteed Destec's performance
pursuant to this lease agreement. See Note 22 for discussion of the effects the
potential sale of Destec's stock would have on the CLI lease guarantee by Dow.
 
    In addition to the aforementioned lease agreement, Destec also leases
certain office space under operating leases.
 
    Future minimum rentals under noncancelable operating leases in effect at
December 31, 1996 are as follows:

16. BENEFIT PLANS
 
    Certain of Destec's officers and employees formerly participated in benefit
plans sponsored by Dow during their employment with Dow. All amounts contributed
or paid by Dow on behalf of Destec's employees pursuant to the Dow plans have
been charged to Destec and are reflected in Destec's

              FOR THE YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
             (IN THOUSANDS OF DOLLARS, UNLESS OTHERWISE INDICATED)
 
16. BENEFIT PLANS (CONTINUED)
consolidated financial statements. Dow satisfied all pension obligations related
to these employees and officers prior to the implementation of Destec's own
benefit plans and, accordingly, no accrued benefit obligation was transferred to
Destec. Deferred defined compensation contracts (the "Agreements") were extended
to former Dow employees in order to replace the future value of their then
vested interest in the Dow benefit plans. These contracts provide for certain
future payments which accrue over various terms of future employment to be made
to these employees upon retirement, termination, or in certain cases, a change
in the control of Destec, to supplement the Destec deferred tax savings plan
which was implemented at the same date and which is outlined below. Should
Destec be unable to perform under the Agreements, Dow has guaranteed these
payments which were $2,689 and $2,833 as of December 31, 1996 and 1995,
respectively. See Note 22 for discussion of the effects the proposed merger of
Destec with a wholly owned subsidiary of NGC would have on Dow's guaranty
related to these payments.
 
    The Destec Energy, Inc. Retirement and Savings Plan ("Retirement and Savings
Plan") is a deferred tax savings plan which covers all of its full-time
employees. Amounts owed to the Retirement and Savings Plan (including amounts
withheld from employees and not yet paid to the plan) and included in ACCRUED
LIABILITIES for 1996 and 1995, were $6,416 and $3,765, respectively. Destec
recorded expenses of $3,204, $3,274 and $2,776 for the years ended 1996, 1995
and 1994, respectively, related to this plan. Additionally, Destec has a
non-qualified deferred compensation plan and an executive salary continuation
plan pursuant to which certain key officers and/or former employees of Destec
participate.
 
    As a result of operational defects in the administration of the Retirement
and Savings Plan since 1991, Destec filed a Voluntary Compliance Report ("VCR")
with the Internal Revenue Service ("IRS"). If the VCR application is approved by
the IRS, Destec will make a contribution to the Plan of approximately $4,689
(before tax effect) including accrued interest (included in ACCRUED LIABILITIES
as discussed above). Destec's management believes that adequate reserves are
provided as of December 31, 1996 for this potential liability.
 
    Effective January 1, 1994, Destec adopted an unfunded defined benefit
postretirement plan for continuation of group medical benefits which is
accounted for under SFAS No. 106 "Employers' Accounting for Postretirement
Benefits other than Pensions." Upon eligible retirement, Destec contributes
(with certain caps) 50% of group medical premium cost for employees and
dependents. The accumulated postretirement benefit obligation is $1,091 which
will be amortized over approximately 10 years. The significant assumptions used
in the valuation of this obligation were a 1996 discount rate of 7.5%, an
average retirement age of 65 and the 1983 Group Annuity Mortality Table. Destec
recorded expenses of $238 and $320 for the years ended December 31, 1996 and
1995, respectively, for service costs and amortization of the accumulated
postretirement benefit obligation related to this plan.
 
    Between May 1994 and September 1996, Destec entered into severance and
services agreements (the "Agreements") with certain employees, fourteen of which
are remaining as of December 31, 1996. Each Agreement provides that in the event
of a change in control of Destec, and the termination of the employee, under
certain circumstances the employee is entitled to receive (i) certain severance
and/or advisory service payments equal in the aggregate to two times the sum of
(a) annual salary plus (b) average annual bonus over the preceding three years
(payment would include a pro rata portion of an employee's current year target
bonus if termination occurs during the year), (ii) the continuation of certain
benefits for two years, and (iii) reimbursement of certain legal fees that may
be incurred (generally not to exceed $25

per employee). The terms of the Agreements continue through December 31, 1997,
with automatic one-year extensions beginning on January 1, 1997, unless the
Company gives notice of non-extension by September 30 of the preceding year.
Under the Agreements, a change in control of Destec includes: (i) any change
required to be reported under Regulation 14A of the Securities Exchange Act of
1934, (ii) with the exception of The Dow Chemical Company, any entity acquiring
20% or more of the combined voting power of Destec's common stock, (iii) any
change in the current Board of Directors during any subsequent two year period
which would result in the current Board being less than a majority, or (iv) if
all or substantially all of the assets of Destec are sold, liquidated or
distributed. Under certain of these Agreements, employees may be required to
provide advisory services to the Company for up to one year after termination of
employment in the event of a change of control. The Company's maximum contingent
liability for these severance and advisory service payments is estimated to be
approximately $12,000 at December 31, 1996. The proposed merger of Destec with a
wholly owned subsidiary of NGC (see Note 22) constitutes a change in control
under the Agreements.
 
17. STOCK COMPENSATION PLANS
 
    At December 31, 1996, Destec has stock-based compensation plans under which
shares or options could be granted to employees. Destec measures compensation
cost for those plans using the intrinsic value method of accounting prescribed
by APB Opinion No. 25 "Accounting for Stock Issued to Employees." Given the
terms of the plans, no compensation cost has been recognized for the fixed stock
option plans or the stock purchase plan.
 
    Destec's reported net income and earnings per share would have been reduced
had compensation cost for Destec's stock-based compensation plans been
determined using the fair value method of accounting as set forth in SFAS No.
123 "Accounting for Stock-Based Compensation." For purposes of estimating the
fair value disclosures below, the fair value of each stock option has been
estimated on the grant date with a Black-Scholes option-pricing model using the
following weighted-average assumptions: dividend yield of 0%; expected
volatility of 29.69%; risk-free interest rate of 6.35%; and expected lives of 10
years for fixed stock option plans and 0.83 years for the Stock Purchase Plan.
The effects of using the fair value method of accounting on net income and
earnings per share are indicated in the pro forma amounts below:

Destec may grant up to 1% of the total outstanding shares of common stock on the
first day of such year, increased in any year by 25% of the shares available. As
of December 31, 1996, there were 56,079,260 shares outstanding. The option price
per share may not be less than the fair market value on the date the option is
granted and

STOCK PURCHASE PLANS
 
    Destec has an Employees' Stock Purchase Plan (the "Purchase Plan") which
offers employees of Destec the right to purchase shares of the Company's common
stock. The employees are eligible to subscribe for shares at a price set by the
Company's Stock Award Committee up to 10% of each employee's gross annual salary
as of the beginning of the plan year. The purchase price of the stock is 85% of
the market price at the measurement date. Approximately 36% to 57% of the
eligible employees have participated in the Purchase Plan in the last three
years.

DEFERRED STOCK PLANS
 
    Under the 1990 Plan, Destec grants deferred stock to certain employees. The
vesting period for such grants is generally 5 years. After the vesting period,
the shares are issued to the employee. The number of deferred stock awards
granted prior to 1993, in February 1993 and in February 1996 were 71,600, 38,900
and 16,100, respectively. Total awards exercised and forfeited as of December
31, 1996 were 17,600 and 37,850, respectively. Compensation expense equal to the
fair market value of the shares on the date of the grant is recognized in the
period of the grant and amounted to $207, $369 and $310 for 1996, 1995 and 1994,
respectively. The number of deferred shares outstanding were 71,150, 77,300 and
90,800 as of December 31, 1996, 1995 and 1994, respectively.
 
1995 VARIABLE PAY PLAN
 
    In 1995, as part of Destec's variable pay plan, Destec offered all full-time
employees the opportunity to take a portion of their individual cash awards in
restricted stock. The restricted stock would vest at the end of each of the next
three years. In addition, if Destec achieved certain thresholds, as defined by
the Compensation Committee, the Company would match each restricted share with a
deferred share. Destec expensed $779 and $1,425 in 1996 and 1995, respectively.
During 1996, 219,556 shares were issued; of this amount, 92,183 shares were
vested and 4,195 shares were canceled, leaving 123,178 shares outstanding as of
December 31, 1996.
 
    See Note 22 for discussion of the effects the proposed merger of Destec with
a wholly owned subsidiary of NGC would have on the stock-based compensation
plans.
 
18. RESTRUCTURING CHARGES
 
    In September 1994, Destec's management finalized a study to refocus its
business development efforts from domestic to international markets and to
de-emphasize vertical integration. In order to implement

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
              FOR THE YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
             (IN THOUSANDS OF DOLLARS, UNLESS OTHERWISE INDICATED)
 
18. RESTRUCTURING CHARGES (CONTINUED)
this shift in focus, management developed a restructuring plan to reduce and
realign the current work force and reduce overhead. In order to fully implement
this plan, Destec recorded a restructuring charge of $10,000 in 1994 as a
component of operating costs. Components of the charge were approximately $5,500
for termination pay and benefits, $3,100 for vacated lease space (net of
revenues from potential sublease) and $1,400 related to the write-off of
leasehold improvements and office equipment. Destec's remaining accruals
relating to this charge were $1,812 and $3,400 as of December 31, 1996 and 1995,
respectively. Destec's charges against the restructuring accrual were $1,588 and
$4,520 for 1996 and 1995, respectively. The balance remaining at the end of 1996
is for vacated lease space net of sublease revenues.
 
19. COMMITMENTS AND CONTINGENCIES
 
    Destec is a defendant in certain lawsuits in which legal and financial
responsibility cannot be determined at this time. Management believes that
resolution of these matters will not materially affect Destec's Consolidated
Financial Statements.
 
    At December 31, 1996 and 1995, respectively, Destec had outstanding
irrevocable letters of credit from banks totaling $35,401 and $30,996. These
letters of credit are pledged to support certain Destec equity commitments and
other development activities.
 
    See Note 4 for discussion of the LYO Partnership Agreement.
 
    See Note 12 for discussion of the Wabash operating penalty.
 
    See Note 15 for discussion of lease commitments related to the Wabash and
CLI facilities.
 
    Destec contracted in 1993 to design, engineer, build and operate a
cogeneration facility in Polk County, Florida to be owned by a Delaware limited
partnership ("Tiger Bay") in which Destec has an approximate 50% non-controlling
equity interest. Destec has a commitment to loan up to an additional $10,000
(subordinated to the partnership's senior lenders) to the Tiger Bay project
based on the project steam host's ability to contractually perform. In December
1993, Destec entered into a 20 year firm transportation agreement, effective in
March 1995, with Florida Gas Transmission to maintain firm gas transportation
capacity. Destec is required to pay approximately $3,500 per year over the
contract life to maintain transportation capacity. During 1996, Destec sold the
excess capacity which the Tiger Bay project was unable to utilize. Because the
current market rate for natural gas transportation capacity was less than
Destec's contracted cost, a resulting net fuel expense of $2,867 and $2,124 was
incurred in 1996 and 1995, respectively.
 
    Pursuant to an agreement dated September 6, 1996, Destec has agreed to pay
the investment banking firm of Morgan Stanley & Co. Incorporated ("Morgan
Stanley") to assist Destec in exploring strategic alternatives to maximize
shareholder value. If the Merger discussed in Note 22 is consummated, Destec
will pay a total fee of approximately $5,100 (against which any previously paid
fees would be credited) for services performed. If the Merger is not consummated
the fee would be between $200 and $450. In addition to the foregoing
compensation, Destec has agreed to reimburse Morgan Stanley for its expenses,
including reasonable fees and expenses of its counsel, and to indemnify Morgan
Stanley for liabilities and expenses arising out of the engagement and the
transactions in connection therewith, including liabilities under federal
securities laws.

19. COMMITTMENTS AND CONTINGENCIES (CONTINUED)
 
    In January 1997, Tiger Bay Limited Partnership, in which Destec holds an
equity interest of approximately 50%, executed an agreement for the sale of the
Tiger Bay cogeneration facility, located in Fort Meade, Florida to a wholly
owned subsidiary of Florida Power Corporation for $445,000. Destec's estimated
share of the proceeds after repayment of partnership debt and the net settlement
of other partnership obligations is anticipated to be approximately $140,000.
The sale is subject to certain conditions, including regulatory approvals and
the closing of the proposed merger of Destec and NGC (see Note 22).
 
    Destec has entered into a long-term gas supply agreement for approximately
30 Mmcf per day of natural gas to be supplied at market prices to seven of the
California cogeneration facilities in which Destec owns an equity interest. The
term of this agreement is for a 10-year period, expiring in 2002, with
provisions for a 5-year renegotiated extension.
 
20. MAJOR CUSTOMERS
 
    The following represents the percentages of revenue from individual sources
which exceed 10% of Destec's total revenue:

(1) Destec's sales to electric utilities increased significantly in 1996. The
    CLI facility, which contributed approximately 16% of Destec's total revenue,
    is currently operating slightly above a break-even point. The majority of
    the CLI facility's sales are to HL&P at tariff prices approved by the Public
    Utilities Commission of Texas for cogenerators. During 1996, DPS sold power
    on behalf of CLI to various utility customers. The Wabash facility began
    operating in November 1995 and contributed approximately 5% of Destec's
    total revenue through sales to PSI (see Note 12). The remainder of sales to
    Electric Utilities resulted from DPS marketing power from various sources to
    a number of different electric utilities.
 
(2) The Los Mina facility, located in the Dominican Republic, commenced
    commercial operations in the second quarter of 1996 and sells power to
    Corporacion Dominicana de Electricidad which is a government owned utility
    in the Dominican Republic.
 
(3) Revenues related to the Elsta, Kingston, Michigan Power, Tiger Bay and
    Wabash projects result from development, engineering and operating
    activities necessary to construct and operate these facilities.

22. EVENTS SUBSEQUENT TO DECEMBER 31, 1996
 
    On January 17, 1997, Tiger Bay Limited Partnership, in which Destec holds an
equity interest of approximately 50%, executed an agreement for the sale of the
nominally rated 220 MW Tiger Bay cogeneration facility, located in Fort Meade,
Florida to a wholly owned subsidiary of Florida Power Corporation for
approximately $445,000. Destec's estimated share of the proceeds after repayment
of partnership debt and the net settlement of other partnership obligations is
anticipated to be approximately $140,000. The sale is subject to certain
conditions, including, without limitation, regulatory approvals and the sale of
Destec.
 
    On February 17, 1997, Destec executed an Agreement and Plan of Merger (the
"Merger Agreement"), by and among Destec, Dow, NGC Corporation ("NGC") and NGC
Acquisition Corporation II, a wholly owned subsidiary of NGC ("Purchaser"),
pursuant to which, among other things, Purchaser will merge with and into Destec
(the "Merger"). The surviving corporation after the Merger will be a wholly
owned subsidiary of NGC. Pursuant to the Merger Agreement, among other things,
each outstanding share of common stock of Destec will be converted into the
right to receive $21.65 in cash (the "Merger Consideration"), or approximately
$1,270,000 in the aggregate. The consummation of the Merger is subject to
certain conditions, including the approval by the affirmative vote of at least
66 2/3% of the outstanding shares of Destec common stock entitled to vote, as
well as the approval by federal antitrust authorities and the Federal Energy
Regulatory Commission. Dow, which owns 80% of the outstanding common stock, has
agreed to vote its shares of common stock for approval and adoption of the
Merger Agreement.
 
    Destec has various agreements with its principal stockholder, Dow and its
subsidiaries and affiliates (the "Dow Agreements"). Certain of the Dow
Agreements and certain agreements among Destec, Dow and NGC entered into on
February 17, 1997, will be affected by the consummation of the Merger Agreement
and the transactions contemplated thereby, as described below.
 
    The Merger Agreement provides that, upon the consummation of the Merger, NGC
and Purchaser will cause Dow to be released as an obligor under the following
agreements: (i) Guaranty, dated as of August 11, 1995, by Dow for the benefit of
CoGen Funding, Limited Partnership relating to Dow's guarantee of the payment of
the lease obligations of CLI (the "CLI Guaranty"); and (ii) Guaranty, dated as
of December 18, 1991, by Dow in favor of Destec and certain identified
individuals, relating to Dow's guarantee of the performance of Destec of its
obligations under certain compensation adjustment agreements with Destec
employees formerly employed by Dow (the "Compensation Guaranty").
 
    In connection with the release of Dow as obligor under the CLI Guaranty, NGC
and Dow have entered into an Indemnity Agreement, dated as of February 17, 1997,
whereby NGC has agreed to use its reasonable best efforts to terminate the CLI
Guaranty or substitute NGC in Dow's stead under the CLI Guaranty; and in any
event, indemnify Dow against any losses arising out of the CLI Guaranty. In
connection with the release of Dow as obligor under the Compensation Guaranty,
Destec, Dow, and NGC have entered into a Waiver, Release and Substitution
agreement, dated as of February 17, 1997, whereby

    Destec and Dow have entered into a First Amendment to the Tax Sharing
Agreement, dated February 17, 1997 pursuant to which the most recent tax sharing
agreement between Dow and Destec was amended to provide, among other things, (i)
the provisions of such tax sharing agreement apply to this deconsolidation of
Destec from the consolidated group of corporations for which Dow files tax
returns for U.S. Federal income tax purposes; (ii) on the Closing Date of the
Merger Agreement, Dow will pay to Destec $10,000 as an advance payment of
amounts expected to be paid to Destec under such tax sharing agreement with
respect to the 1997 tax year; (iii) Dow will be treated as having actually
utilized all deduction, losses, credits and other tax attributes of Destec prior
to Destec's deconsolidation, with the effect that Destec will be entitled to
payments for such items by Dow pursuant to such tax sharing agreement; and (iv)
Destec will not be liable to Dow for taxes with respect to certain transactions.
The First Amendment to the Tax Sharing Agreement will be effective as of the
Effective Time of the Merger Agreement.
 
    Pursuant to the First Amended Lease Agreement, dated as of January 1, 1990,
as amended between Destec Properties Limited Partnership, a wholly owned
subsidiary of Destec ("Destec Properties"), and Dow, Dow has given notice that
it is exercising its option to purchase all of Destec's interest in certain
specific lignite reserves. The exercise price of approximately $44,000 will be
paid to Destec immediately prior to the effective time of the Merger.
Consequently, Destec Properties and Dow have entered into (i) a Termination
Agreement Concerning the First Amended Lease Agreement, entered into February
17, 1997, to become effective as of the effective time of the Merger and (ii) a
Termination Agreement concerning the First Amended Lignite Properties
Maintenance Agreement, entered into February 17, 1997, to become effective at
the effective time of the Merger, pursuant to which Destec will provide limited
consulting and training with respect to the management and maintenance of the
lignite reserves to Dow at no additional cost.
 
    Pursuant to the Oyster Creek Agreement, dated February 17, 1997, by and
among Destec, Dow and NGC, Dow has obtained a right of first refusal with
respect to the stock of certain Destec subsidiaries related to the Oyster Creek
cogeneration facility and waived its right to exercise an option to purchase the
partnership interests of such company subsidiaries in Oyster Creek Limited that
would become exercisable in the event Dow no longer holds a majority interest of
the common stock of Destec.
 
    Pursuant to a Site Development Agreement, dated February 17, 1997, by and
between Dow and Destec, for five years, Dow will include Destec in the Dow
notification to potential third party (power company) bidders with respect to
energy generation facility projects at certain Dow sites put to bid and invite
the Company to participate in the bid process. In the event that Dow does not
provide such notification and an invitation to bid, Dow will pay the Company the
amount of damages which the Company shows it suffered up to a cap of $25 per
project.

22. EVENTS SUBSEQUENT TO DECEMBER 31, 1996 (CONTINUED)
Destec engaged Dow to provide certain research and development services with
respect to intellectual property relating to gasification of carbonaceous
materials and to lignite beneficiation, which intellectual property was assigned
to Destec by Dow pursuant to an Assignment Agreement, dated March 1, 1990. The
First Amendment to Research & Development Agreement provides, in pertinent part,
the term of the Research & Development Agreement will continue through December
31, 1997, unless the parties otherwise agree to in writing, and further
identifies three individual Dow employees that will continue to provide research
and development support services pursuant to such agreement, with Dow receiving
$125 per man year of effort (for a total of 2 1/2 man years) as compensation for
such services. In addition, the amendment deleted the parties' undertaking
relative to further joint technology development made in the Research &
Development Agreement. Pursuant to the Assignment Agreement, Dow assigned to
Destec certain patents and technology. The First Amendment to Assignment
Agreement modifies the license granted to Dow and its subsidiaries to practice
the technology pertaining to gasification of carbonaceous materials and to
lignite beneficiation and any improvements to such technology so as to apply
only to improvements made prior to December 31, 1997 (or prior to any extension
of the term of such agreement). In addition, the First Amendment to Assignment
Agreement terminates Dow's license to Destec to use certain hardware and
software and also terminated Destec's right of refusal to perform design,
engineering and construction services to any coal gasification facility Dow
desired to construct and operate.

Destec with copies of all Section 16(a) forms they file.
 
    Based solely on its review of the forms received by it and written
representations from certain reporting persons that they were not required to
file Forms 5 for the fiscal year ended December 31, 1996, Destec believes that
during the year ended December 31, 1996, all filing requirements applicable to
Destec's officers, directors and greater than 10% stockholders were met.

(1) The positions shown represent the offices held by such persons as of
    December 31, 1996.
 
(2) Bonuses earned during 1995 were paid under Destec's 1995 Variable Pay Plan
    and include (i) cash amounts paid and (ii) the value, as of the date of
    grant, of awards of restricted stock and deferred stock. Shares of
    restricted stock and deferred stock were paid to each of the Named Executive
    Officers in the following amounts: Mr. Goff, 18,300 shares of restricted
    stock and 18,300 shares of deferred stock; Mr. Curry, 15,250 shares of
    restricted stock and 15,250 shares of deferred stock; Mr. Larroucau, 10,167
    shares of restricted stock and 10,167 shares of deferred stock; Mr. Webb,
    4,933 shares of restricted stock and 4,933 shares of deferred stock; and Mr.
    Mann, 2,914 shares of restricted stock and 2,914 shares of deferred stock.
    Thirty-three percent of such shares of restricted stock will vest on
    December 31 of each of 1996, 1997 and 1998. Thirty-three percent of such
    shares of deferred stock will vest on December 31 of each of 1996, 1997 and
    1998 if the fair market value of the Common Stock achieves certain targets
    during the 30-day period preceding such date. Under the terms of the 1995
    Variable Pay Plan, immediately prior to a change in control, each awardee
    will be entitled to receive, in cancellation of all then outstanding awards
    of restricted or deferred stock and in lieu of shares of Common Stock
    otherwise deliverable in respect of such awards, an amount in cash (subject
    to applicable withholding) equal to the per share consideration received in
    connection with such change in control multiplied by the aggregate number of
    shares of restricted stock and deferred stock subject to such award. Holders
    of restricted stock have the right to receive dividends during the
    restriction period.
 
(3) With the exception of Messrs. Larroucau and Mann, the amounts ascribed to
    personal benefits for each Named Executive Officer were below the required
    disclosure threshold amounts. When Mr. Larroucau joined Destec in June 1993,
    Destec agreed to pay for his temporary housing and moving expenses incurred
    in 1993 and 1994. Amounts shown for Mr. Mann represent foreign service
    premiums, rental subsidies, foreign tax advances and foreign fringe
    benefits.
 
(4) The payment of shares of restricted stock and deferred stock earned during
    1995 under Destec's 1995 Variable Pay Plan is reported in the 1995 "Bonus"
    column of this table. The number and aggregate value (each as of December
    31, 1996) of each of the Named Executive Officers' aggregate restricted
    stock and deferred stock holdings are as follows: Mr. Goff, 24,400 shares
    with a value of $381,250; Mr. Curry, 20,334 shares with a value of $317,719;
    Mr. Larroucau, 13,556 shares with a value of $211,813; Mr. Webb, 6,578
    shares with a value of $102,781; and Mr. Mann, 3,886 shares with a value of
    $60,719. On December 31, 1996, thirty-three percent of the shares of
    restricted stock and thirty-three percent of the shares of deferred stock
    paid under the 1995 Variable Pay Plan vested.

(5) With the exception of Mr. Larroucau, the amounts shown in this column
    represent Destec contributions to Destec's Retirement and Savings Plan for
    each Named Executive Officer. The amounts shown for Mr. Larroucau include
    payments made on Mr. Larroucau's behalf in connection with his pension
    account with Dow's International Employee Pension Plan during 1994. Mr.
    Larroucau's pension account with Dow became dormant effective January 1,
    1995.

- ------------------------
 
(1) Destec made no SAR grants in 1996. All options granted to Named Executive
    Officers in 1996 will vest ratably over a three-year period that began
    February 21, 1996.
 
(2) In 1996, a total of 649,850 options to purchase Common Stock were granted to
    Destec employees at a per share exercise price of $12.3125 and 33,500 at a
    per share exercise price of $14.9375.
 
(3) The exercise price is the average of the high and low trading price of the
    Common Stock on the date of grant, as reported on the consolidated
    transaction reporting system for the NYSE issues on such date.
 
(4) The values assigned to each reported option are shown using the
    Black-Scholes option pricing model. In assessing these values it should be
    kept in mind that no matter what theoretical value is placed on an option on
    the date of grant, its ultimate value will be dependent on the market value
    of the Common Stock at a future date, and that value will depend on the
    efforts of such executives to foster the future success of Destec for the
    benefit of not only the executives, but all of Destec's stockholders.

SEVERANCE AND SERVICES AGREEMENTS
 
    Destec has entered into severance and services agreements (the "Services
Agreements") with certain of its employees, of which 14 are remaining as of
December 31, 1996. The Named Executive Officers currently covered by such
Services Agreements include Messrs. Goff, Curry, Larroucau, Webb and Mann. In
addition, Messrs. Bowen, Hess and Jackowski and Ms. Davenport, who serve as
executive officers of Destec, are also covered by such Services Agreements. Each
Services Agreement provides that in the event of a change of control of Destec,
and the termination of the employee under certain circumstances, the employee is
entitled to receive (i) certain severance and/or advisory service payments equal
in the aggregate to two times the sum of (a) annual salary plus (b) average
annual bonus over the preceding three years, (ii) a pro rata target bonus in
respect of the year in which termination occurs , (iii) the continuation of
certain benefits for two years, and (iv) reimbursement of certain legal fees and
expenses incurred as a result of such termination (not to exceed $25,000 per
employee). Under Mr. Goff's Services Agreement, Destec would also be required to
make an additional payment to the extent that any excise tax is imposed under
Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code"). Each
of the remaining Services Agreements provides that no payment shall be made to
an individual that would not be deductible by virtue of Section 280G of the
Code. The terms of the Services Agreements continue through December 31, 1997,
with automatic one-year extensions beginning on January 1, 1997, unless Destec
gives a notice of non-extension by September 30 of the preceding year. Under the
Services Agreements, a Change of Control of Destec includes: (i) any change
required to be reported under Regulation 14A of the Securities Exchange Act of
1934, (ii) with the exception of Dow, any entity acquiring 20% or more of the
combined voting power of Destec's common stock, (iii) any change in the current
Board of Directors during any subsequent two year period which would result in
the current Board being less than a majority, or (iv) a circumstance where all
or substantially all of the assets of Destec are sold, liquidated or
distributed. Under certain of these agreements, employees may be required to
provide advisory services to Destec for up to one year after termination of
employment in the event of a Change of Control. Destec's maximum contingent
liability for these severance and advisory service payments is estimated to be
approximately $12 million at December 31, 1996. The consummation of the Merger
will constitute a Change of Control under the Services Agreements. See Note 22
of the Notes to Consolidated Financial Statements.
 
COMPENSATION ADJUSTMENT AGREEMENTS
 
    Beginning in November 1991, Destec entered into Compensation Adjustment
Agreements ("Compensation Agreements") with former Dow employees in order to
induce these employees to leave the Dow benefit plans and join Destec. These
Compensation Agreements provide for certain future payments to be made to these
employees upon retirement, termination, and in certain cases, a change in the
control of Destec. These Compensation Agreements supplement Destec's deferred
tax savings plan to ensure that these employees would receive the pension
benefits they would have accrued had they remained employed by Dow.
 
    Messrs. Charles F. Goff and Rodney M. Webb, each a Named Executive Officer,
will receive payments under Compensations Agreement when they each retire from
Destec. The amount to be received by each officer was calculated by (i)
projecting his Dow pension at the earliest date it is unreduced ("Projection
Date"), (ii) subtracting both the projected Destec contribution to him under
Destec's deferred tax savings plan and any pension amounts the individual would
receive from Dow from his projected Dow pension, and (iii) annuitizing the
short-fall. In the event any of these employees remain employed by Destec beyond
the Projection Date, he will continue to accrue benefits under his Compensation
Agreement. Assuming a retirement age of 65, Messrs. Goff and Webb would be
eligible to receive a lump sum payment of $763,152 and $612,321, respectively.

SALARY CONTINUATION PLAN
 
    In 1986, PSE Inc., which is now known as Destec Holdings, Inc. ("DHI"),
established the PSE Executive Salary Continuation Plan (the "Salary Continuation
Plan") for certain of its executives. The Salary Continuation Plan will pay the
beneficiary of a deceased participant on a monthly basis over a period not to
exceed 180 months following his/her death while employed or after total and
permanent disability or retirement an amount not to exceed one-half of the
participant's salary at the time of death (or time of disability or retirement).
The Salary Continuation Plan is an unfunded, nonqualified death benefit plan.
DHI financed the Salary Continuation Plan through the use of corporate-owned
life insurance on the lives of participants. Mr. Keys A. Curry, Jr. is the only
remaining executive officer of the Company who is a participant in the Salary

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The current members of Destec's Compensation Committee are Messrs. Jack E.
Earnest, Robert W. Gallant and Michael D. Parker. Mr. Enrique J. Sosa, who
served on the Compensation Committee during 1996, resigned from the Board of
Directors, and thereby the committee, effective February 22, 1996. Mr. Parker
was elected to fill this position on May 1, 1996. The service of these
individuals on the Compensation Committee does not create any corporate
interlocks or insider participation between Destec's Compensation Committee and
another entity.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
THE DOW AGREEMENTS
 
    Destec has various agreements with Dow, its principal stockholder (the "Dow
Agreements"), some of which were entered into when Destec was a wholly owned
subsidiary of Dow and, therefore, are not the result of arm's length
negotiations between two independent parties. Since the date of Destec's initial
public offering, Destec's Audit Committee has adopted policies and procedures to
deal with any conflicts of interest between Destec and Dow, including any
conflict of interest under the Dow Agreements. Any modifications to existing
agreements and the execution of new agreements between Destec and Dow are
negotiated in accordance with the Audit Committee's policies. All agreements,
including the agreements set forth below, comport with such policies. The
paragraph below describes agreements involving amounts exceeding $60,000 entered
into between Destec and Dow since December 31, 1995.
 
    Destec and Dow have entered into a Tax Sharing Agreement, effective May 15,
1996 (the "Tax Sharing Agreement"), which provides for payments between Destec
and Dow with respect to certain taxes. The Tax Sharing Agreement applies to
taxes paid by Dow with respect to its consolidated U.S. federal income tax
return and state and local combined tax returns that include Destec. With
respect to federal income taxes, the amount of Destec's payment to Dow is based
on the amount of tax Destec would pay if it filed its returns on a stand-alone
basis. With respect to state and local taxes, Destec generally bears its pro
rata share of combined tax liability. Pursuant to the Tax Sharing Agreement, Dow
is required to make payments to Destec for certain tax attributes of Destec used
by Dow to reduce its tax liability.
 
    Destec and Dow have entered into a First Amendment to the Tax Sharing
Agreement, dated February 17, 1997, pursuant to which the Tax Sharing Agreement
was amended to provide, among other things, that (i) the provisions of such tax
sharing agreement apply to the deconsolidation of Destec from the consolidated
group of corporations for which Dow files tax returns for U.S. Federal income
tax purposes; (ii) on the closing date of the Merger, Dow will pay to Destec $10
million as an advance payment of amounts expected to be paid to Destec under
such tax sharing agreement with respect to the 1997 tax year; (iii) Dow will be
treated as having actually utilized all deductions, losses, credits and other
tax attributes of Destec and its subsidiaries prior to Destec's deconsolidation,
with the effect that Destec will be entitled to payment for such items by Dow
pursuant to such tax sharing agreement; and (iv) Destec will not be liable to
Dow for taxes with respect to certain transactions. The First Amendment to the
Tax Sharing Agreement will be effective as of the Effective Time under the
Merger Agreement.
 
    In June 1996, Destec and Dow entered into a settlement agreement regarding
the decommissioning of a facility near Plaquemine, Louisiana, constructed by Dow
in 1987 and in which Destec had an interest (the "LGTI Facility"), pursuant to
which the LGTI equipment and all related facilities (except the slag pile) would
be transferred to Dow. Destec has agreed to reimburse Dow for clean-up and
disposal expenses up to a maximum of $250,000. Destec has agreed to remove the
slag pile at the site in compliance with applicable federal, state and local
requirements. The cost of removal is expected to be offset by proceeds from the
sale of the slag.
 
    See Note 22 of the Notes to Consolidated Financial Statements for a
description of certain agreements between Destec and Dow entered into in
connection with the Merger Agreement.
 
SEVERANCE AND SERVICES AGREEMENTS
 
    Since January 1, 1996, Destec has entered into a Service Agreement with one
executive officer. See "Executive Compensation--Severance and Services
Agreements."

         Section 1.1  CERTIFICATES.  Every holder of stock in the Company shall
be entitled to have a certificate signed in the name of the Company by the
Chairman of the Board of Directors or the President or an Executive Vice
President or a Vice President, and by the Treasurer or an Assistant Treasurer or
the Secretary or an Assistant Secretary of the Company certifying the number of
shares in the Company owned by such holder. If such certificate is countersigned
(a) by a transfer agent other than the Company or its employee, or, (b) by a
registrar other than the Company or its employee, any other signature on the
certificate may be a facsimile. In case any officer, transfer agent, or
registrar who has signed or whose facsimile signature has been placed upon a
certificate shall have ceased to be such officer, transfer agent, or registrar

effect as if such person were such officer, transfer agent, or registrar at the

a class of stock shall be numbered consecutively. A record of the name and
address of the holder of each certificate, the number of shares represented
thereby and the date of issue thereof shall be made on the Company's books. The

Board of Directors, give the Company a bond, in such form as may be approved by
the General Counsel or his or her staff, sufficient to indemnify the Company
against any claim that may be made against it on account of the alleged loss of
the certificate or the issuance of a new certificate.

    Section 1.5  TRANSFER AGENTS; REGISTRARS: RULES RESPECTING CERTIFICATES. 
The Board of Directors may appoint, or authorize any officer or officers to

notice of and to vote at such meeting and any adjournment thereof, or to

                                SECTION II
                        MEETINGS OF STOCKHOLDERS

     Section 2.1  ANNUAL MEETING.  The annual meeting of the holders of such 
classes or series of stock as are entitled to notice hereof and to vote 
thereat pursuant to the provisions of the Certificate of Incorporation (the 
"Annual Meeting of Stockholders") for the election of Directors and for the 
transaction of such other business as may properly come before the meeting 
shall be held on such date as the Board of Directors shall each year fix. 
Each such annual meeting shall be held at such place, within or without the 
State of Delaware, and hour as shall be determined by the Board of Directors. 
The day, place and hour of each annual meeting shall be specified in the 
notice of annual meeting pursuant to Section 2.4 of this Section II.

    The annual meeting of stockholders may be adjourned by the presiding
officer of the meeting for any reason (including, if the presiding officer
determines that it would be in the best interests of the Company to extend the
period of time for the solicitation of proxies) from time to time and place to
place until the presiding officer shall determine that the business to be
conducted at the meeting is completed, which determination shall be conclusive.

    At an annual meeting of the stockholders, only such business shall be
conducted as shall have been properly brought before the meeting. To be properly
brought before an annual meeting, business must be (a) specified in the notice
of meeting (or any supplement thereto) given by or at the direction of the Board
of Directors; (b) otherwise properly brought before the meeting by or at the
direction of the 


                                 Page 3 of 24      As Amended December 6, 1996

<PAGE>

Board of Directors; or (c) otherwise properly brought before the meeting by a 
stockholder. For business to be properly brought before an annual meeting by 
a stockholder, the stockholder must have given timely notice thereof in 
writing to the Secretary of the Company. To be timely, a stockholder's notice 
must be delivered to or mailed and received at the principal executive 
offices of the Company, not less than 60 days nor more than 180 days prior to 
the anniversary date of the immediately preceding annual meeting; provided, 
however, that in the event that the date of the annual meeting is more than 
45 days later than the anniversary date of the immediately preceding annual 
meeting, notice by the stockholder to be timely must be received not later 
than the close of business on the tenth day following the date on which 
notice of the date of the annual meeting was mailed or public disclosure was 
made. A stockholder's notice to the Secretary shall set forth as to each 
matter the stockholder proposes to bring before the annual meeting (a) a 
brief description of the business desired to be brought before the annual 
meeting, (b) the name and address, as they appear on the Company's books, of 
the stockholder proposing such proposal; (c) the class and number of shares 
of the Company which are beneficially owned by the stockholder, and (d) any 
material interest of the stockholder in such business. In addition, if the 
stockholder's ownership of shares of the Company, as set forth in the notice, 
is solely beneficial, documentary evidence of such ownership must accompany 
the notice. Notwithstanding anything in the Bylaws to the contrary, no 
business shall be conducted at an annual meeting except in accordance with 
the procedures set forth in this Section 2.1. The presiding officer of an 
annual meeting shall, if the facts warrant, determine and declare to the 
meeting that any business which was not properly brought before the meeting 
is out of order and shall not be transacted at the meeting.

    Section 2.2  SPECIAL MEETINGS.  Except as otherwise required by law,
special meetings of the stockholders may be called only by the Chairman of the
Board, the President, or the Board of Directors pursuant to a resolution
approved by a majority of the entire Board of Directors. Each special meeting


                                 Page 4 of 24      As Amended December 6, 1996

<PAGE>

shall be held at such place, within or without the State of Delaware, and 
hour as shall be determined by the Board of Directors. The day, place and 
hour of each special meeting shall be specified in a notice of special 
meeting. At any special meeting of stockholders, only such business shall be 
conducted as shall be provided for in the resolution or resolutions calling 
the special meeting or, where no such resolution or resolutions have been 
adopted, only such business shall be conducted as shall be provided in the 
notice to stockholders of the special meeting. Any special meeting of 
stockholders may be adjourned by the presiding officer of the meeting for any 
reason (including, if the presiding officer determines that it would be in 
the best interests of the Company to extend the period of time for the 
solicitation of proxies) from time to time and from place to place until the 
presiding officer shall determine that the business to be conducted at the 
meeting is completed, which determination shall be conclusive.

    Section 2.3  STOCKHOLDER ACTION; HOW TAKEN.  Any action required or
permitted to be taken by the stockholders of the Company must be effected at a
duly called annual or special meeting of such holders and may not be effected by
any consent in writing by such holders.

    Section 2.4  NOTICE OF MEETING.  Subject to Section VI of these Bylaws,
notice of every meeting of the stockholders shall be given in the manner
prescribed by law.

    Section 2.5  QUORUM.  Except as otherwise required by law, the Certificate
of Incorporation or these Bylaws, the holders of not less than one-third of the
shares entitled to vote at any meeting of the stockholders, present in person or
by proxy, shall constitute a quorum and the act of the majority of such quorum
shall be deemed the act of the stockholders.

    If a quorum shall fail to attend any meeting, the presiding officer of the
meeting may adjourn the meeting to another place, date or time, without notice
other than announcement at the meeting. If the adjournment is for more than 30
days, or if after the adjournment a new record date is fixed for the 


                                 Page 5 of 24      As Amended December 6, 1996

<PAGE>

adjourned meeting, a notice of the adjourned meeting shall be given to each 
stockholder entitled to vote at the meeting.

    If a notice of any adjourned special meeting of stockholders is sent to all
stockholders entitled to vote thereat, stating that it will be reconvened with
those present constituting a quorum, then except as otherwise required by law,
those present at such reconvened meeting shall constitute a quorum and all
matters shall be determined by a majority of votes cast at such reconvened
meeting.

    Section 2.6  VOTING LIST.  The officer who has charge of the stock ledger
of the Company shall prepare and make, at least ten days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice, or if not
so specified, at the place where the meeting is to be held. The list shall also
be produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

    Section 2.7  VOTING.  When a quorum is present at any meeting of the
stockholders, 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 is one upon which, by express
provision of the statutes, of the Certificate of 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. Every stockholder having the
right to vote shall be entitled to vote in person, or by proxy appointed by an
instrument in writing signed by such stockholder (which for purposes of this
section may include a signature and form of proxy pursuant to a facsimile or
telegraphic form of proxy or any other instrument 


                                 Page 6 of 24      As Amended December 6, 1996

<PAGE>

acceptable to the Inspector of Election), bearing a date not more than three 
years prior to voting, unless such instrument provides for a longer period, 
and filed with the Secretary of the Company before, or at the time of, the 
meeting. If such instrument shall designate two or more persons to act as 
proxies, unless such instrument shall provide to the contrary, a majority of 
such proxies present at any meeting at which their powers thereunder are to 
be exercised shall have and may exercise all the powers of voting or giving 
consents thereby conferred, or if only one be present, then such powers may 
be exercised by that one; or, if a majority does not agree on any particular 
issue, each proxy so attending shall be entitled to exercise such powers in 
respect of the same portion of the shares as he is of the proxies 
representing such shares.

    Section 2.8  VOTING OF STOCK OF CERTAIN HOLDERS.  Shares standing in the
name of another corporation, domestic or foreign, may be voted by such officer,
agent or proxy as the Bylaws of such corporation may prescribe, or in the
absence of such provisions, as the Board of Directors of such corporation may
determine, in either case either specifically with respect to such shares or
generally with respect to any action to be taken by such corporation. Shares
standing in the name of a deceased person may be voted by the executor or
administrator of such deceased person, either in person or by proxy. Shares
standing in the name of a guardian, conservator or trustee may be voted by such
fiduciary, either in person or by proxy, but no such fiduciary shall be entitled
to vote shares held in such fiduciary capacity without a transfer of such shares
into the name of such fiduciary. Shares standing in the name of a receiver may
be voted by such receiver. A stockholder whose shares are pledged shall be
entitled to vote such shares, unless in the transfer by the pledgor on the books
of the Company, he has expressly empowered the pledgee to vote thereon, in which
case only the pledgee, or his proxy, may represent the stock and vote thereon.

indirectly, shares of its own stock owned by it; and such shares shall not be
counted in determining the total number of outstanding shares.

procedure at every meeting of the stockholders shall be determined by the
presiding officer of the meeting, who shall be the Chairman of the Board of
Directors, the President or such other officer of the Company as designated by
the Board. The presiding officer of the meeting shall have all the powers and
authority vested in a presiding officer by law or practice without restriction,
including, without limitation, the authority, in order to conduct an orderly
meeting, to impose reasonable limits on the amount of time at the meeting taken
up in remarks by any one stockholder and to declare any business not properly
brought before the meeting to be out of order. The presiding officer of each
meeting shall appoint one or more Inspectors of Election to serve at every
meeting of the stockholders.

                                  SECTION VII

                                INDEMNIFICATION

     Section 7.1  THIRD PARTY ACTIONS. The Company shall indemnify, to the 
full extent permitted by the laws of the State of Delaware, any person who 
was or is a party or is threatened to be made a party to any threatened, 
pending or completed action, suit or proceeding, whether civil, criminal, 
administrative or investigative (other than an action by or in the right of 
the Company), by reason of the fact that such person (a) is or was a 
director, officer or employee of the Company, or (b) is or was a director, 
officer or employee of the Company and is or was serving at the request of 
the Company as a director, officer, employee or agent of another corporation, 
partnership, joint venture, trust or other enterprise, against expenses 
(including attorneys' fees), judgments, fines and amounts paid in settlement 
actually and reasonably incurred by such person in connection with such 
action, suit or proceeding if such person acted in good faith and in a manner 
he reasonably believed to be in or not opposed to the best interests of the 
Company, and, with respect to any criminal action or proceeding, had no 
reasonable cause to believe his or her conduct was unlawful. The termination 
of any action, suit or proceeding by judgment, order, 


                                Page 19 of 24      As Amended December 6, 1996

<PAGE>

settlement or conviction, or upon a plea of nolo contendere or its 
equivalent, shall not, of itself, create a presumption that such person did 
not act in good faith and in a manner which such person reasonably believed 
to be in or not opposed to the best interests of the Company, nor, with 
respect to any criminal action or proceeding, that such person had reasonable 
cause to believe that his or her conduct was unlawful. Any repeal, amendment 
or modification of this Section 7.1 shall not affect any rights or 
obligations then existing between the Company and any then incumbent or 
former director, officer or employee with respect to any state of facts then 
or theretofore existing or any action, suit or proceeding theretofore or 
thereafter brought based in whole or in part upon such state of facts.

     Section 7.2  ACTIONS BY OR IN THE RIGHT OF THE CORPORATION.  The Company 
shall indemnify, to the full extent permitted by the laws of the State of 
Delaware, any person who was or is a party or is threatened to be made a 
party to any threatened, pending or completed action or suit by or in the 
right of the Company to procure a judgment in its favor by reason of the fact 
that such person (a) is or was a director, officer or employee of the 
Company, or (b) is or was a director, officer or employee of the Company and 
is or was serving at the request of the Company as a director, officer, 
employee or agent of another corporation, partnership, joint venture, trust 
or other enterprise, against expenses (including attorneys' fees) actually 
and reasonably incurred by such person in connection with the defense or 
settlement of such action or suit if such person acted in good faith and in a 
manner such person reasonably believed to be in or not opposed to the best 
interests of the Company and except that no indemnification shall be made in 
respect of any claim, issue or matter as to which such person shall have been 
adjudged to be liable to the Company unless and only to the extent that the 
Court of Chancery or the court in which such action or suit was brought shall 
determine upon application that, despite the adjudication of liability but in 
view of all the circumstances of the case, such person is fairly and 
reasonably entitled to indemnity for such expenses which the Court of 
Chancery or such other court shall 


                                Page 20 of 24      As Amended December 6, 1996

<PAGE>

deem proper. Any repeal, amendment or modification of this Section 7.2 shall 
not affect any rights or obligations then existing between the Company and 
any then incumbent or former director, officer or employee with respect to 
any state of facts then or theretofore existing or any action, suit or 
proceeding theretofore or thereafter brought based in whole or in part upon 
such state of facts.

     Section 7.3  SUCCESS ON THE MERITS.  To the extent that a director, officer
or employee of the Company has been successful on the merits or otherwise in
defense of any action, suit or proceeding referred to in Sections 7.1 and 7.2
herein, or in defense of any claim, issue or matter therein, such person shall
be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by such person in connection therewith.

     Section 7.4  INDEMNIFICATION OF AGENTS.  The Company may, to the extent
deemed advisable by the Board of Directors, indemnify any person who is or was
an agent (other than a director, officer or employee) of the Company, if such
person would be entitled to such indemnity under the provisions of the preceding
three paragraphs had such person been acting in the capacity of a director,
officer or employee of the Company.

     Section 7.5  DETERMINATION OF CONDUCT.  Any indemnification under Sections
7.1, 7.2 and 7.4 herein (unless ordered by a court) shall be made by the Company
only as authorized in the specific case upon a determination that
indemnification of the director, officer, employee or agent is proper in the
circumstances because such person has met the applicable standard of conduct set
forth in Sections 7.1, 7.2 and 7.4 herein.

     Such determination shall be made (a) by the Board of Directors by a
majority vote of the directors who were not parties to such action, suit or
proceeding, even though less than a quorum, or (b) if there are no such
directors, or if such directors so direct, by independent legal counsel in a
written opinion.

     Section 7.6  PAYMENT OF EXPENSES IN ADVANCE.  Expenses (including
attorneys' fees) incurred in defending a civil, criminal, administrative or
investigative action, suit or proceeding shall be paid by the Company in advance
of the final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of the director, officer or employee, to repay such
amount if it shall ultimately be determined that such person is not entitled to
be indemnified by the Company as authorized in this Section VII.

     Section 7.7  DEFINITIONS.  For purposes of this Section VII references to
"the Company" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers and employees
or agents, so that any person who is or who was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under the provisions of this Section VII, with
respect to the resulting or surviving corporation as such person would have with
respect to such constituent corporation if its separate existence had continued.
For purposes of this Section VII, references to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the Company" shall include any service
as a director, officer, employee or agent of the Company which imposes duties
on, or involves services by, such director, officer, employee or agent with
respect to any employee benefit plan, its participants, or beneficiaries; and a
person who acted in good faith and in a manner he reasonably believed to be in
the interest of the participants and beneficiaries of an employee benefit plan
shall be deemed to have acted in a manner "not opposed to the best interests of
the Company" as referred to in this Section VII.

     Section 7.8  INDEMNITY NOT EXCLUSIVE.  The indemnification and advancement
of expenses provided by, or granted pursuant to, the other Sections of this
Section VII shall not be deemed exclusive of any other rights to which those
seeking indemnification or advancement of expenses may be entitled under any
other bylaw, agreement, vote of stockholders or disinterested directors or
otherwise both as to action by the person in an official capacity and as to
action in another capacity while holding such office, it being the policy of the
Company that indemnification of the persons specified in Sections 7.1 or 7.2
above shall be made to the fullest extent permitted by the laws of the State of
Delaware.  The provisions of this Section VII shall not be deemed to preclude
the indemnification of any person who is not specified in Sections 7.1 or 7.2
above, but whom the Company has the power or obligation to indemnify under the
laws of the State of Delaware or otherwise.

     Section 7.9  SURVIVAL OF INDEMNIFICATION AND ADVANCEMENT OF EXPENSES. The
indemnification and advancement of expenses provided by, or granted pursuant to,

administrators of such person.

     Section 7.10  INSURANCE.  The Company may purchase and maintain insurance
on behalf of any person who is or was a director, officer, employee or agent of
the Company, or is or was serving at the request of the Company as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, against any liability asserted against and incurred
by such person in any such capacity, or arising out of the person's status as
such, whether or not the Company would have the power or the obligation to
indemnify the director, officer, employee or agent of the Company against such
liability under the provisions of this Section VII.

                      SEVERANCE AND SERVICES AGREEMENT 

May 21, 1996

Marian M. Davenport


Dear Marian:

     Destec Energy, Inc., a Delaware corporation (the "Company") considers it 
essential to the best interests of its stockholders to foster the continuous 
employment of key management personnel. Further, the Board of Directors of 
the Company (the "Board") recognizes that the possibility of a change in 
control exists, and that such possibility, and the uncertainty and questions 
which it may raise among management, may result in the departure or 
distraction of management personnel to the detriment of the Company and its 
stockholders.

     The Board has determined that appropriate steps should be taken to 
reinforce and encourage the continued attention and dedication of members of 
the management of the Company and its subsidiaries, including yourself, to 
their assigned duties without distraction in the face of potentially 
disturbing circumstances arising from any possible change in control of the 
Company.

     In order to induce you to remain in the employ of the Company, the 
Company agrees that you shall receive the severance benefits set forth in 
this letter agreement (this "Agreement") in the event your employment with 
the Company is terminated subsequent to a Change in Control (as defined in 
Section 2 hereof) under the circumstances described below. In addition, in 
order to procure for the Company and its stockholders the benefits of your 
expertise and experience following a termination of your employment, this 
Agreement also sets forth terms pursuant to which you will provide consulting 
services.

     1.  TERM OF AGREEMENT.  The term of this Agreement (the "Term") shall 
commence on the date hereof and shall continue in effect through December 31, 
1996; provided, however, that commencing on January 1, 1997 and each January 
1 thereafter, the original Term of this Agreement shall automatically be 
extended for one additional year unless, not later than September 30 of the 
preceding year, the Company shall have given notice that it does 


<PAGE>

not wish to extend the Term. Notwithstanding any such notice by the Company 
not to extend the Term, if a Change in Control shall have occurred during the 
original or extended Term, the Term shall continue in effect for a period of 
twenty-four (24) months beyond the Term in effect immediately before such 
Change in Control.

     2.  CHANGE IN CONTROL.  No benefits shall be payable hereunder unless 
there shall have been a Change in Control, as set forth below. For purposes 
of this Agreement, a "Change in Control" shall mean a change in control of 
the Company of a nature that would be required to be reported in response to 
Item 6(e) of Schedule 14A of Regulation 14A promulgated under the Securities 
Exchange Act of 1934, as amended (the "Exchange Act"), whether or not the 
Company is then subject to such reporting requirement; provided that, 
without limitation, a Change in Control shall be deemed to have occurred if:

     (A)  with the exception of The Dow Chemical Company, any individual, 
partnership, firm, corporation, association, trust, unincorporated 
organization or other entity, or any syndicate or group deemed to be a 
person under Section 14(d)(2) of the Exchange Act, is or becomes the 
"beneficial owner" (as defined in Rule 13d-3 of the General Rules and 
Regulations under the Exchange Act), directly or indirectly, of securities of 
the Company representing 20% or more of the combined voting power of the 
Company's then outstanding securities entitled to vote in the election of 
directors of the Company;

     (B)  during any period of two (2) consecutive years (not including any 
period prior to the execution of this Agreement) individuals who at the 
beginning of such period constituted the Board and any new directors, whose 
election by the Board or nomination for election by the Company's 
stockholders was approved by a vote of at least three-quarters (3/4) of the 
directors then still in office who either were directors at the beginning of 
the period or whose election or nomination for election was previously so 
approved, cease for any reason to constitute a majority thereof; or

     (C)  all or substantially all of the assets of the Company are sold, 
liquidated or distributed.

     If the Company executes an agreement, the consummation of which results 
in the occurrence of a Change in Control as described above, then a Change in 
Control shall be deemed to have occurred as of the date of the execution of 
such agreement.

     3.  TERMINATION FOLLOWING CHANGE IN CONTROL.  If any of the events 
described in Section 2 hereof constituting a Change in Control shall have 
occurred, you shall be entitled to the benefits provided in Subsection 4(D) 
hereof upon the subsequent termination of your employment during the Term 
unless such termination is because of your death or Retirement, by the 
Company for Cause or Disability, or by you other than for Good Reason.


                 

<PAGE>

          (A)  DISABILITY; RETIREMENT.  If, as a result of your incapacity 
due to physical or mental illness, you shall have been absent from the 
full-time performance of your duties with the Company for six (6) consecutive 
months, and within thirty (30) days after written Notice of Termination is 
given you shall not have returned to the full-time performance of your 
duties, the Company may terminate your employment for "Disability."  Any 
question as to the existence of your Disability upon which you and the 
Company cannot agree shall be determined by a qualified independent physician 
selected by you (or, if you are unable to make such selection, it shall be 
made by any adult member of your immediate family), and approved by the 
Company. The determination of such physician made in writing to the Company 
and to you shall be final and conclusive for all purposes of this Agreement.  
Termination of your employment based on "Retirement" shall mean your 
voluntary termination of employment on a Retirement Date as defined in the 
Company's Retirement and Savings Plan (the "Retirement Plan") as in effect 
immediately prior to the occurrence of a Change in Control whether or not you 
are a participant in the Retirement Plan or in accordance with any retirement 
arrangement established with your consent with respect to you.

          (B)  CAUSE.  Termination by the Company of your employment for 
"Cause" shall mean termination upon (i) the willful and continued failure by 
you substantially to perform your duties with the Company (other than any 
such failure resulting from your incapacity due to physical or mental 
illness or from your Retirement or any such actual or anticipated failure 
resulting from termination by you for Good Reason) after a written demand for 
substantial performance is delivered to you by the Board, which demand 
specifically identifies the manner in which the Board believes that you have 
not substantially performed your duties, or (ii) the willful engaging by you 
in conduct which is demonstrably and materially injurious to the Company, 
monetarily or otherwise.  For purposes of this Subsection, no act or failure 
to act on your part shall be deemed "willful" unless done, or omitted to be 
done, by you not in good faith and without reasonable belief that your action 
or omission was in the best interest of the Company.  Notwithstanding the 
foregoing, you shall not be deemed to have been terminated for Cause unless 
and until there shall have been delivered to you a copy of a resolution duly 
adopted by the affirmative vote of not less than three-quarters (3/4) of the 
entire membership of the Board at a meeting of the Board called and held for 
such purpose (after reasonable notice to you and an opportunity for you, 
together with your counsel, to be heard before the Board), finding that in 
the good faith opinion of the Board you were guilty of conduct set forth 
above in clause (i) or (ii) of the first sentence of this Subsection and 
specifying the particulars thereof in detail.

          (C)  GOOD REASON.  You shall be entitled to terminate your 
employment for Good Reason.  For purposes of this Agreement, "Good Reason" 
shall mean, without your express written consent, any of the following:


                      

<PAGE>

          (i)    INCONSISTENT DUTIES.  A meaningful and detrimental 
     alteration in your position or in the nature or status of your 
     responsibilities (including those as a director of the Company, if any)
     from those in effect immediately prior to the Change in Control;

          (ii)   REDUCED SALARY OR BONUS OPPORTUNITY.  A reduction by the 
     Company in your annual base salary as in effect on the date hereof or 
     as the same may be increased from time to time; a failure by the Company
     to increase your salary at a rate commensurate with that of other key 
     executives of the Company; or a reduction in your annual bonus below the
     greater of (a) the annual bonus which you received, or to which you were
     entitled, immediately prior to the Change in Control, or (b) the average
     annual bonus paid to you by the Company for the three years preceding the
     year in which the Change in Control occurs;

          (iii)  RELOCATION.  The relocation of the office of the Company 
     where you are employed at the time of the Change in Control (the "CIC 
     Location") to a location which in your good faith assessment is an area 
     not generally considered conducive to maintaining the executive offices 
     of a company such as the Company because of hazardous or undesirable 
     conditions including without limitation a high crime rate or inadequate
     facilities, or to a location which is more than fifty (50) miles away 
     from the CIC Location or the Company's requiring you to be based more 
     than fifty (50) miles away from the CIC Location (except for required 
     travel on the Company's business to an extent substantially consistent 
     with your customary business travel obligations in the ordinary course 
     of business prior to the Change in Control);

          (iv)   COMPENSATION PLANS.  The failure by the Company to continue 
     in effect any compensation plan in which you participate prior to the 
     Change in Control, unless an equitable arrangement (embodied in an 
     ongoing substitute or alternative plan) has been made with respect to 
     such plan in connection with the Change in Control, or the failure by the
     Company to continue your participation therein on at least as favorable 
     a basis, both in terms of the amount of benefits provided and the level

          herein as the "Salary Factor"), plus

               (2) an amount (the "Bonus Factor") calculated by multiplying

          average percentage bonus (annualized in the case of any bonus paid 
          with respect to a partial year) paid to you in respect of the three 
          years preceding the Date of Termination, (or the period of your 
          employment, if less than three (3) years) determined for each such 
          year as a percentage of the base salary paid to you in respect of

          to you in respect of the three years preceding the Change in 
          Control, (or the period of your employment, if less than three (3) 
          years) determined for each such year as a percentage of the base 
          salary paid to you in respect of the relevant year.

          (iii)  LEGAL FEES AND EXPENSES.  The Company shall also pay to you 
     all legal fees and expenses incurred by you as a result of such

     enforce any right or benefit provided by this Agreement), provided,

     benefits substantially similar to those which you are receiving 
     immediately prior to the Notice of Termination.  Benefits otherwise 
     receivable by you pursuant to this Subsection 4(D) (iv) shall be reduced 
     to the extent comparable benefits are actually received by you during

     such benefits actually received by you shall be reported to the Company.

          (v)  EMPLOYEE BENEFIT PLANS.  You shall be entitled to receive all

<PAGE>

by seeking other employment or otherwise, nor shall the amount of any payment 
or benefit provided for in this Section 4 be reduced by any compensation 
earned by you as the result of employment by another employer or by pension 
benefits after the Date of Termination, or otherwise except as specifically 
provided in this Section 4.

          5.  ADVISORY ARRANGEMENT.  If your employment by the Company shall 
be terminated by the Company other than for Cause, Retirement or Disability 
or by you for Good Reason, then for a period of 0 months following the date 
of such termination of employment (the "Advisory Period"), you shall be 
engaged by the Company as an advisor on the following terms and conditions:

          (A)  ADVISORY SERVICES.  During the Advisory Period you will 
perform advisory services for the Company and its subsidiaries as the Board 
may reasonably request from time to time, it being understood that you will 
be expected to provide at least 0 days of advisory services.  You agree to 
make yourself available on a reasonable basis during the Advisory Period to 
provide such services.  Advisory services will be performed at times and 
places mutually convenient to you and the Company.

          (B)  INDEPENDENT CONTRACTOR.  As an advisor to the Company you will 
act in the capacity of an independent contractor and not as an employee of 
the Company.  The Company will not exercise discretion or control over you in 
the performance of your advisory services, nor shall it require your 
compliance with orders or instructions.  You will act solely in an advisory 
capacity and in consequence will not have authority to act for the Company or 
to give instructions or orders on behalf of the Company or to make any 
decisions or commitments for or on behalf of the Company.

          (C)  COMPENSATION.  The Company will pay you, in consideration for 
the advisory services to be provided hereunder, an aggregate amount equal to 
0 times the sum of the Salary Factor and the Bonus Factor, plus reimbursement 
of your reasonable out of pocket expenses.  Such amount shall be paid in 
equal monthly installments over the term of the Advisory Period.  The Company 
retains the right to withhold and deduct from any such payment all sums which 
it may be required to deduct or withhold pursuant to applicable law.

          6.  REDUCTION OF PAYMENTS IN CERTAIN CASES.  Notwithstanding 
anything herein to the contrary, in no event will the Company be obligated to 
make any payments to you that would not be deductible by virtue of Section 
280G(a) of the Internal Revenue Code of 1986, as amended (the "Code").  If, 
for purposes of Section G of the Code, any amount or benefit otherwise due to 
you under this Agreement (including without limitation any amount due to 
you pursuant to Section 5) and under any other plan or program of the Company 
(including without limitation any amount attributable to the accelerated 
vesting of any stock options upon a Change in Control) would constitute a 
"parachute payment", as such term is


                                                                 

<PAGE>

defined in Section 280G(b)(2) of the Code, then the aggregate of such amounts 
will be reduced to $1.00 less than the minimum amount that would result in 
any such payments being considered a "parachute payment." The determination 
to be made with respect to this Section 6 shall be made by an accounting firm 
(the "AUDITOR") jointly selected by the Company and you and paid by the 
Company. If you and the Company cannot agree on the firm to serve as the 
Auditor, then you and the Company shall each select one accounting firm and 
these two firms shall jointly select the accounting firm to serve as the 
Auditor. If a determination is made by the Auditor that a reduction in the 
aggregate of all payments due to you upon a Change in Control is required by 
this Section 6, you shall have the right to specify the portion of such 
reduction, if any, that will be made under this Agreement and each plan or 
program of the Company (which reduction may include, without limitation, the 
waiver of the accelerated vesting of any stock options). If you do not so 
specify within 60 days following the date of a determination by the Auditor 
pursuant to the preceding sentence, the Company shall determine, in its sole 
discretion, the portion of such reduction, if any, to 
be made under this Agreement and each plan or program of the Company.

     7.  SUCCESSORS; BINDING AGREEMENT.

         (A)  ASSUMPTION BY SUCCESSOR.  The Company will require any 
successor (whether direct or indirect, by purchase, merger, consolidation or 
otherwise) to all or substantially all of the business and/or assets of the 
Company to expressly assume and agree to perform this Agreement in the same 
manner and to the same extent that the Company would be required to perform 
it if no such succession had taken place. As used in this Agreement, the 
"Company" shall mean the Company as hereinbefore defined and any successor to 
its business and/or assets as aforesaid which assumes and agrees to perform 
this Agreement by operation of law, or otherwise.

         (B)  ENFORCEABILITY BY BENEFICIARIES.  This Agreement shall inure to 
the benefit of and be enforceable by your personal or legal representatives, 
executors, administrators, successors, heirs, distributees, devisees and 
legatees, If you should die while any amount would still be payable to you 
hereunder if you had continued to live, all such amounts, unless otherwise 
provided herein, shall be paid in accordance with the terms of this Agreement 
to your devisee, legatee or other designee or, if there is no such designee, 
to your estate.

     8.  NOTICE.  For the purpose of this Agreement, notices and all other 
communications provided for in the Agreement shall be in writing and shall be 
deemed to have been duly given when delivered or mailed by United States 
registered mail, return receipt requested, postage prepaid, addressed to the 
Vice President, Human Resources, with a copy to the General Counsel of the 
Company, or to you at the address set forth on the first page of this

<PAGE>

furnished to the other in writing in accordance herewith, except that notice 
of change of address shall be effective only upon receipt.

     9.  MISCELLANEOUS.  No provision of this Agreement may be modified, 
waived or discharged unless such waiver, modification or discharge is agreed 
to in writing.  No waiver by either party hereto at any time of any breach by 
the other party hereto of, or compliance with, any condition or provision of 
this Agreement to be performed by such other party shall be deemed a waiver 
of similar or dissimilar provisions or conditions at the same or at any prior 
or subsequent time.  No agreements or representations, oral or otherwise, 
express or implied, with respect to the subject matter hereof have been made 
by either party which are not expressly set forth in this Agreement and this 
Agreement shall supersede all prior agreements, negotiations, correspondence, 
undertakings and communications of the parties, oral or written, with respect 
to the subject matter hereof.

    10.  VALIDITY.  The invalidity or unenforceability of any provision of 
this Agreement shall not affect the validity or enforceability of any other 
provision of this Agreement, which shall remain in full force and effect.

    11.  COUNTERPARTS.  This Agreement may be executed in several counterparts,
each of which shall be deemed to be an original but all of which together 
will constitute one and the same instrument.

    12. ARBITRATION.  Any dispute or controversy arising under or in 
connection with this Agreement shall be settled exclusively by arbitration in 
Houston, Texas in accordance with the rules of the American Arbitration 
Assocation then in effect.  Judgment may be entered on the arbitrator's award 
in any court having jurisdiction.

    13.  NO CONTRACT OF EMPLOYMENT.  Nothing in this Agreement shall be 
construed as giving you any right to be retained in the employ of the Company.

    14.  HEADINGS.  The headings contained in this Agreement are intended 
solely for convenience and shall not affect the rights of the parties to this 
Agreement.

    15.  GOVERNING LAW.  The validity interpretation, construction, and 
performance of this Agreement shall be governed by the laws of the State of 
Delaware applicable to contracts entered into and performed in such State.

    16.  SOURCE OF PAYMENTS.  All payments provided under this Agreement, 
other than payments made pursuant to a benefit plan which may provide 
otherwise, shall be paid in cash from the general funds of the Company, and 
no special or separate fund shall be established, and no other segregation of 
assets made, to assure payment.  You shall have no right, title or interest 
whatever in or 


                         

<PAGE>


to any investments which the Company may make to aid the Company in meeting 
its obligations hereunder.  Nothing contained in this Agreement, and no 
action taken pursuant to its provisions, shall create or be construed to 
create a trust of any kind, or a fiduciary relationship, between the Company 
and you or any other person.  To the extent that you or any other person 
acquires a right to receive payments from the Company hereunder, such right 
shall be no greater than the right of an unsecured creditor of the Company.

     If this letter sets forth our agreement on the subject matter hereof, 
kindly sign and return to the Company the enclosed copy of this letter which 
will then constitute our agreement on this subject.

                                       Sincerely,

                                       DESTEC ENERGY, INC.

jurisdiction, multiplied by (iii) the total tax liability, net of any tax 
credits, reflected on such Combined Return.

less than zero), determined without reference to any carrybacks or 
carryforwards of any net operating loss, net capital loss, charitable 
contribution or other item attributable to any other taxable period, as 
determined on a basis that is consistent with the manner in which the Members

filing the Consolidated Return (and any Combined Return).

Agreement on a consolidated basis, including but not limited to, providing 
promptly to the requesting party such assistance and documentation (at the 
expense of the providing party if related to any Taxable Year) as may be 
requested by such party in connection with the preparation or filing of the 
Consolidated Return (and any Combined Return), and the conduct of any audit 
or other examination, or judicial or administrative proceeding or 
determination relating thereto.

     3.  FILING OF RETURNS.

     (a)  APPOINTMENT OF DOW AS AGENT FOR CONSOLIDATED RETURN.  Destec and 
each of its Subsidiaries hereby appoint Dow as their agent, with respect to 
all periods during which Destec or such Subsidiary, as the case may be, is a 
Member of the Dow Group, for the purpose of filing the Consolidated Return 
and of making any election or application or taking any action in connection 
therewith on behalf of Destec and such Subsidiary.  Nothing herein shall be 
construed as requiring Dow to file a Consolidated Return for any Taxable Year; 
PROVIDED, HOWEVER, that if Dow decides not to file a Consolidated Return it 
shall notify Destec in writing within a period reasonably sufficient to 
permit Destec to file timely returns for Members of the Destec Group.

     (b)  DOW CONTROL OVER CONSOLIDATED RETURN.  Dow shall prepare and file, 
or cause to be prepared and filed, the Consolidated Return and any other 
documents or statements required to be filed with the Service that pertain to

Taxable Year of the Dow Group.  In its sole and absolute discretion, but 
after prior good faith consultation with Destec on issues which impact the 
Destec Group Consolidated

<PAGE>

Tax Liability (if requested by the Tax Director of Destec), Dow shall have 
the right with respect to any Consolidated Return that it has filed or will 
file to determine (regardless of the manner in which an item or matter may 
have been reported by Destec on a Pro Forma Destec Return):

          (i) the manner in which such Consolidated Return, as well as any 
     other documents or statements incidental or related thereto shall be 
     prepared and filed, including without limitation, the manner in which 
     any item of income, gain, loss, deduction, expense or credit of Destec 
     or any Subsidiary of Destec shall be reported therein or thereon;

          (ii) whether any extensions (including extensions of the date for 
     filing or any statute of limitations) with respect to any Consolidated 
     Return will be requested;

          (iii) the elections that will be made in any such Consolidated 
     Return by any Member, including without limitation, elections by Destec 
     or any Subsidiary of Destec;

          (iv) whether to file an amended Consolidated Return and to prosecute,
     compromise or settle any claim for refund set forth therein; and

          (v) whether any refunds to which the Dow Group may be entitled 
     shall be passed by way of cash refund or credited against the Dow Group 
     Consolidated Tax Liability for any Taxable Year or Taxable Years of the 
     Dow Group.

Destec and each Subsidiary of Destec hereby irrevocably appoints Dow as its 
agent and attorney-in-fact to take any action (including the execution of 
documents) as Dow may deem appropriate to effect the foregoing.  Nothing 
contained in this Agreement shall limit Dow's discretion to determine the 
manner in which any item shall be reported on the Consolidated Return.


                                       9

<PAGE>

     (c)  APPOINTMENT OF DOW AS AGENT FOR CERTAIN COMBINED RETURNS.  Destec 
and each Subsidiary of Destec hereby appoint Dow as their agent with respect 
to all periods during which Destec or such Subsidiary, as the case may be, is 
a Member of the Dow Group, for the purpose of filing any Combined Return that 
Dow (or any Subsidiary of Dow, other than Destec or any of its Subsidiaries) 
may elect to file, and for making any election or application or taking any 
action (including any extension of statutes of limitation) in connection 
therewith on behalf of Destec and such Subsidiary.  Destec and each of its 
Subsidiaries hereby consent to the filing of such returns, and to the making 
of such elections and applications.  Nothing contained in this Agreement 
shall be construed as requiring Dow or any Subsidiary of Dow to file a 
Combined Return on behalf of Destec or any Subsidiary of Destec for any 
Taxable Year.  Dow shall in its sole and absolute discretion determine 
whether and with respect to which jurisdictions Destec or any of its 
Subsidiaries shall participate in the filing of any Combined Return.

     (d)  OTHER RETURNS.  Destec and its Subsidiaries shall be solely 
responsible for filing all tax returns not described in subsections (b) and 
(c) of this Section 3 and that relate solely to Destec and/or its 
Subsidiaries.

     (e)  ASSISTANCE AND RESPONSIBILITY FOR SUPPORT OF RETURNS; PROVISION OF 
FINANCIAL DATA.  Destec and its Subsidiaries shall assist Dow in the filing, 
to the extent permitted by law, of a Consolidated Return and such Combined 
Returns as Dow elects to file or cause to be filed, by maintaining such books 
and records and providing such information as may be necessary or useful in 
the filing of such returns and executing any documents and taking any actions 
which Dow may reasonably request in connection therewith including without 
limitation designing and implementing systems, processes and programs for the 
compilation and review of financial data; the review of transactions and 
accounting methods; and the preparation of returns and of supporting 
documentation to assure that such returns and all related reports and 
schedules are complete and accurate.  Destec 


                                       10

<PAGE>


shall, at its own expense, provide Dow with all information required by Dow 
to reflect completely and accurately the financial results of the Destec 
Group in the Dow Group's Consolidated Return (or a Combined Return).  Such 
information shall be in such form as determined by Dow from time to time and 
shall be delivered to Dow on a mutually agreed upon date, but in no event 
later than the first business day in June of the year following such Taxable 
Year.  Destec shall, at its own expense, maintain sufficient books, records 
and expertise to support all returns, positions taken thereon and methods 
used to prepare such returns until there has been a Final Determination with 
respect to all issues included on such returns.  Dow and Destec shall provide 
one another with such other information concerning such returns and the 
application of payments made under this Agreement as Dow or Destec may 
reasonably request of one another.

     4.  PRO FORMA DESTEC RETURN.

     (a)  INITIAL PREPARATION OF PRO FORMA DESTEC RETURN.  For each Taxable 
Year for which a Consolidated Return is filed and Destec or any Subsidiary of 
Destec is a Member of the Dow Group, Destec shall prepare on behalf of the 
Destec Group a pro forma consolidated federal income tax return as the Common 
Parent of the Destec Group (the "Pro Forma Destec Return") covering that 
portion of the Taxable Year in which the Destec Group is included in the Dow 
Group.  The Pro Forma Destec Return shall be complete and accurate, and shall 
be in such form and include such information as shall be determined from time 
to time by Dow.  The Pro Forma Destec Return shall be prepared in accordance 
with subsections (b) and (c) of this Section 4 and shall report the 
consolidated federal taxable income (including, for all purposes of this 
Agreement, alternative minimum taxable income) for such Taxable Year that, 
the Destec Group would have reported if it had not been included in the 
Consolidated Return filed for the Dow Group with respect to such Taxable Year 
and all prior Pro Forma Destec Returns had been actual returns.  The 
provisions of the Code that require consolidated calculations, including 


                                      11


<PAGE>

without limitation, sections 861, 1201, 1212 and 1231, shall be applied 
separately to the Destec Group, but with any simplifying conventions approved 
or suggested by the Tax Director of Dow. The Pro Forma Destec Return shall 
include gains and losses with respect to deferred intercompany transactions 
if, and only if, and to the extent that, such gains or losses are actually 
restored and reflected on the Dow Group's Consolidated Return.

     (b) STANDARDS FOR POSITIONS TAKEN ON PRO FORMA DESTEC RETURN.  Destec 
shall prepare the Pro Forma Destec Return by reporting the tax treatment of 
any item by utilizing such positions that, in Destec's discretion, are 
appropriate for the Destec Group; provided, that each position is more likely 
than not to be ultimately sustained; and provided further that the elections 
made and the positions taken by Destec on the Pro Forma Destec Return shall 
be consistent with the elections made and the positions reflected on the 
relevant portion of the Dow Group's Consolidated Return (including carryovers 
or carrybacks of net operating losses, net capital losses, excess tax credits 
or other tax attributes from prior or subsequent taxable years). Destec may 
utilize a position on the Pro Forma Destec Return that does not meet this 
standard but that does have a reasonable basis in law and in fact; BUT ONLY 
IF Destec has obtained, after prior notice to and consultation with Dow, 
Dow's written consent to utilize such position on Pro Forma Destec Return for 
such Taxable Year. Except as otherwise required by tax law, Destec may not 
utilize a position on the Pro Forma Destec Return that is inconsistent with 
any position utilized on a Pro Forma Destec Return or Consolidated Return for 
a prior taxable year.

     (c) STANDARDS FOR METHODS AND ELECTIONS ON PRO FORMA DESTEC RETURN.  The 
Pro Forma Destec Return shall reflect any elections made and tax accounting 
methods used by Dow with respect to the Dow Group's Consolidated Return that 
in the sole and absolute discretion of Dow, but after prior good faith 
consultation with Destec (if requested by the Tax Director of Destec), should 
be made, taken or



                                      12

<PAGE>

used consistently by the Dow Group in filing such Consolidated Return. Destec 
may utilize any other election, method or simplifying convention subject to 
Dow's approval, which approval shall not be unreasonably withheld, in 
preparing the Pro Forma Destec Return. Notwithstanding the foregoing, Destec 
may not utilize any election or method in preparing the Pro Forma Destec 
Return for a Taxable Year that is inconsistent with any election, position or 
method utilized on a Pro Forma Destec Return or Consolidated Return for a 
prior taxable year if the effect of such treatment is to allow a double 
deduction or benefit with respect to any item (or unless Destec has 
eliminated such double deduction or benefit in a manner acceptable to Dow).

     (d) DELIVERY TO DOW OF PRO FORMA DESTEC RETURN; ASSISTANCE.  Destec will 
deliver to Dow the Pro Forma Destec Return on a mutually agreed date, but in 
no event later than the due date of the Dow Group's Consolidated Return 
(taking into account any extensions thereof that have been granted to Dow). 
Appropriate personnel of Destec or a Destec Subsidiary that are responsible 
for the preparation of the Pro Forma Destec Return shall be available upon 
reasonable notice to meet with appropriate personnel of Dow to discuss all 
aspects of such return and upon request by Dow shall furnish or make 
available for inspection any and all documents used in preparation of the Pro 
Forma Destec Return (documents relied upon by Destec in ascertaining whether 
any position is more likely than not to be ultimately sustained or has a 
reasonable basis in law or in fact shall be furnished only to the principal 
tax legal officer of Dow under cover of the attorney-client privilege and 
work product doctrine).

     (e) ADJUSTMENT BY DOW OF PRO FORMA DESTEC RETURN.  Dow, within 60 days 
of the due date of the Dow Group's Consolidated Return (taking into account 
any extensions thereof that have been granted to Dow) shall adjust the Pro 
Forma Destec Return, as appropriate in accordance with the terms of this 
Agreement and after prior notice to and good faith consultation with Destec, 
to correct any error



                                      13

<PAGE>

of fact or law thereon or any error in mechanical calculation and any failure 
to reflect the principles set forth in this Section 4; provided, however, 
that if Dow proposes an adjustment to the Pro Forma Destec Return because of 
Dow's belief that Destec's position is not more likely than not to be 
sustained and Destec objects to such adjustment, Dow and Destec shall jointly 
select and pay for a nationally recognized law firm to render an opinion as 
to whether the position advocated by Destec is more likely than not to be 
sustained if challenged, in which case, the adjustment proposed by Dow can 
only be made if the opinion from the nationally recognized law firm confirms 
that the position advocated by Destec is NOT more likely than not to be 
sustained if challenged. In the event that Dow and Destec are unable to agree 
on a nationally recognized law firm, Dow shall nominate three such firms 
(excluding the firms of King & Spalding, Miller & Chevalier, and Groom and 
Nordberg) which have not provided Dow significant tax services in the past 
three years, and Destec shall select one of the nominated firms to render 
such opinion if the firm is able to do so. Acceptance by Dow of the Pro Forma 
Destec Return shall not necessarily indicate agreement by Dow nor relieve 
Destec of liability for any adjustment made upon audit or other assessment. 
Similarly, any failure by Dow to properly and fully adjust the Pro Forma 
Destec Return within the 60-day period set forth in this Section 4(e) shall 
not prevent Dow, in its sole and absolute discretion, but after prior good 
faith consultation with the Tax Director of Destec, from making subsequent 
adjustments in accordance with the procedures of this Section 4(e), as 
circumstances warrant within the applicable statute of limitation 
(determined as if the Pro Forma Destec Return were an actual return that is 
subject to any extensions that have been granted by Dow with respect to the 
Consolidated Return) nor relieve Destec of liability for such adjustments. If 
as a result of such adjustment any amounts due to or from Destec under this 
Agreement differ from the corresponding amounts prior to such adjustment, 
payment of such difference shall be made to Destec or



                                      14

<PAGE>

by Destec in the manner provided in Section 9 within 10 days following such 
adjustments.

     (f) UTILIZATION OF CREDITS TO REDUCE DESTEC GROUP CONSOLIDATED TAX 
LIABILITY UNDER CERTAIN CIRCUMSTANCES.  For purposes of computing the Destec 
Group Consolidated Tax Liability for a Taxable Year, the portion of the 
income tax credits described in section 29 of the Code which cannot otherwise 
under this Agreement be utilized by the Destec Group in computing such 
liability because of statutory or income limitations, may be utilized by the 
Destec Group pursuant to this section 4(f) (such unutilized credits shall 
hereinafter be referred to as "Designated Credits").

         (i)  USE OF DESIGNATED CREDITS IN CURRENT TAXABLE YEAR.  Amounts of 
Designated Credits generated in a Taxable Year may be applied to reduce the 
Destec Group Consolidated Tax Liability (including alternative minimum tax 
liability) for the Taxable Year, but not below zero, notwithstanding the 
impact of any statutory or income limitations, but only if and to the extent 
that such Designated Credits reduce the Dow Group Consolidated Tax Liability 
for such Taxable Year.

         (ii) USE OF REFUNDABLE DESIGNATED CREDITS IN CURRENT TAXABLE YEAR.  
The limitation set forth in Section 4(f)(i) of this Agreement that prevents 
Designated Credits from reducing the Destec Group Consolidated Tax Liability 
below zero shall not apply to Refundable Designated Credits. Subject to the 
limitations set forth below, Refundable Designated Credits generated in the 
current Taxable Year may be utilized to reduce the Destec Group Consolidated 
Tax Liability with respect to such Taxable Year below zero (and result in a 
negative amount that is refundable to Destec to the extent provided herein), 
but only if and to the extent that such Refundable Designated Credits reduce 
the Dow Group Consolidated Tax Liability. Notwithstanding the foregoing, 
Destec will not be permitted to utilize



                                      15
<PAGE>

     Refundable Designated Credits with respect to a Taxable Year pursuant to 
     this Section 4(f) in an amount greater than $10 million with respect to 
     any Taxable Year.  Refundable Designated Credits that are utilized shall 
     be applied against the $10 million limitation in the year that they are 
     utilized.  In the event that the amount of Refundable Designated Credits 
     that can be utilized pursuant to this Section 4(f) with respect to a 
     Taxable Year is less than the applicable limitation amount, such excess 
     shall not increase the available limitation in any subsequent Taxable 
     Year.  Dow shall refund in cash to Destec 100% of the Refundable 
     Designated Credits that are permitted to be utilized pursuant to this 
     Section 4(f) within 60 days of the Completion date for such Taxable Year.

          (iii)  DEFINITION OF REFUNDABLE DESIGNATED CREDITS.  For purposes 
     of this Agreement, Refundable Designated Credits are Designated Credits 
     that are generated by resources purchased by the Destec Group prior to 
     May 15, 1996, and cannot be utilized under Section 4(f)(i) solely 
     because of the limitation contained therein that prevents Designated 
     Credits from reducing the Destec Group Tax Liability below zero.  For 
     purposes of determining whether Designated Credits are Refundable 
     Designated Credits with respect to a particular Taxable Year, Designated 
     Credits that reduce the Destec Group Consolidated Tax Liability below 
     zero shall first be considered to have been generated by resources 
     purchased by the Destec Group on or after May 15, 1996, to the extent 
     Designated Credits are generated by such resources in such Taxable Year.

         (iv)  RESTRICTION ON DOUBLE BENEFIT.  Nothing in this Section 4(f) 
     or any other provision of this Agreement shall be construed to entitle 
     Destec or any Subsidiary of Destec to receive a double benefit or 
     compensation with respect to any Designated Credit, Refundable 
     Designated Credit or a carryforward or carryback thereof.  Nothing in 
     this Section 4(f) is intended to limit the Destec Group's ability to 
     carry back or carry forward credits, 


                                       16

<PAGE>

     including Designated Credits or Refundable Designated Credits, pursuant 
     to Section 8(b).

     5.  PAYMENTS BY DESTEC.

     (a)  GENERAL AND DESTEC GROUP CONSOLIDATED TAX LIABILITY.  For each 
Taxable Year of the Dow Group, Destec shall pay to Dow the amount of the 
Destec Group Consolidated Tax Liability and the Destec Group State and Local 
Tax Liability, in the amounts, at the time or times and in the manner as 
herein provided.

          (i) In the event that the estimated Destec Group Consolidated Tax 
     Liability for such Taxable Year is greater than zero, Destec shall make 
     quarterly payments of its estimated Destec Group Consolidated Tax 
     Liability for such Taxable Year.  The amount of each such quarterly 
     payment shall be determined by Destec and shall equal the amount which 
     Destec would be required under Section 6655(d) of the Code (or under any 
     successor section of the Code) to pay to the Service for such quarter 
     were Destec to make installment payments of the Destec Group 
     Consolidated Tax Liability for such Taxable Year in accordance with the 
     provisions of such section.

          (ii) If the actual Destec Group Consolidated Tax Liability for such 
     Taxable Year exceeds the total estimated payments, if any, which Destec 
     made pursuant to Section 5(a)(i) hereof for such Taxable Year, Destec 
     shall pay an amount equal to such excess to Dow.

          (iii) Each of the quarterly payments required to be made by 
     pursuant to Section 5(a)(i) hereof shall be made in the manner provided 
     in Section 9(a) hereof on or before the due date for the payment of the 
     respective quarterly estimate of the Dow Group Consolidated Tax 
     Liability for such Taxable Year.

     (b)  DESTEC GROUP STATE AND LOCAL TAX LIABILITY.  For each Taxable Year 
with respect to which Destec or any of its Subsidiaries particpates in the 
filing of a 


                                       17

<PAGE>

Combined Return, Destec shall pay to Dow, within 30 days of receipt of a bill 
from Dow, the Destec Group's State and Local Tax Liability for such Taxable 
Year.

     (c)  OTHER TAXES.  Destec shall be solely responsible for paying tax 
with respect to all tax returns that Destec or any of its Subsidiaries have 
responsibility for filing pursuant to this Agreement.

     6.  PAYMENTS TO DESTEC.

     (a) For each Taxable Year of the Dow Group, if the payments made by 
Destec pursuant to Section 5(a)(i) hereof of the estimated Destec Group 
Consolidated Tax Liability for such Taxable Year exceeds the actual Destec 
Group Consolidated Tax Liability for such Taxable Year, Dow shall pay to 
Destec an amount equal to such excess.

     (b) Any payment that Destec may be entitled to receive for such Taxable 
Year pursuant to Section 6(a) hereof shall be paid to Destec in the manner 
provided in Section 9(a) hereof on or before 45 calendar days after 
Completion.

     7.  USE OF ATTRIBUTES; ADDITIONAL RIGHTS AND OBLIGATIONS UPON 
         DECONSOLIDATION.

     (a) In determining the Dow Group Consolidated Tax Liability and in 
preparing the Consolidated Return for each taxable year, Dow may utilize on 
behalf of the Dow Group all the tax attributes and other items of income, 
gain, loss, deduction, expense, credit, etc. of Destec and its Subsidiaries 
arising in such taxable year or which arose in another taxable year or 
taxable years and which properly may be carried back or carried forward to 
such taxable year, without regard to whether such attributes and items are 
concurrently being, have previously been or may subsequently be utilized in 
determining for any Taxable Year or Taxable Years, the Destec Group 
Consolidated Tax Liability.  Except as expressly provided in Section 4, 
Section 7(b), and Section 8 of this Agreement, neither Destec nor any of its

                                      18

<PAGE>

Subsidiaries shall in any manner be entitled to any compensation for the use 
of any attributes and other items of income, gain, loss, deduction, expense, 
credit, etc. of Destec and its Subsidiaries.  Moreover, in the event Destec 
or any of its Subsidiaries ceases for any reason to be a Member of the Dow 
Group either (A) after any of its tax attributes or items of income, gain, 
loss, deduction, expense, credit, etc. has been utilized by Dow on behalf of 
the Dow Group in determining the Dow Group Consolidated Tax Liability for any 
Taxable Year or Taxable Years of the Dow Group, but before Destec has 
utilized such attribute or item (in whole or in part) in determining for any 
Taxable Year or Taxable Years, the Destec Group Consolidated Tax Liability or 
(B) after any of its tax attributes or items of income, gain, loss, 
deduction, expense, credit, etc. has been utilized by Destec on behalf of the 
Destec Group in determining the Destec Group Consolidated Tax Liability for 
any Taxable Year or Taxable Years, but before Dow has utilized such attribute 
or item (in whole or in part) in determinig for any Taxable Year or Taxable 
Years, the Dow Group Consolidated Tax Liability, neither Dow nor Destec, as 
the case may be, shall be obligated or required to compensate such other 
party in any manner for any amount as a result of the occurrence of such 
event, except as expressly provided in Section 7(b) below.

     (b) In the event Destec or any of its Subsidiaries ceases for any reason 
to be a Member of the Dow Group, then within 90 days after the filing of the 
Consolidated Return for the last Taxable Year that Destec or such Subsidiary 
was included therein, Dow shall inform Destec or such Subsidiary, as the case 
may be, of the amount of consolidated loss and credit carryovers as of the 
end of the Taxable Year that are allocable to Destec or such Subsidiary, 
pursuant to the Consolidated Return Regulations.  In the event that Dow 
determines that the amount of any particular category of loss or credit 
carryover attributes so allocated to Destec or such Subsidiary exceeds the 
amount of loss and credit attributes of such category (other than Designated 
Credits that reduced the Destec Group Tax Liability for any Taxable Year 
pursuant to Section 4(f) of this Agreement) that


                                      19


<PAGE>

would have been available to Destec or such Subsidiary if the Destec Group 
had not been included in the Dow Group for the current Taxable Year and all 
prior Taxable Years and all Pro Forma Destec Returns had been actual returns, 
then Destec or such Subsidiary shall pay to Dow within 10 days of 
notification of the determination described in this Section 7(b), an amount 
equal to the value of such attributes, as described below. In the event that 
Dow determines that (A) the amount of loss and credit carryover attributes of 
any particular category so allocated to Destec or such Subsidiary is less 
than (B) the amount of the loss and credit attributes of such category (other 
than Designated Credits that reduced the Destec Group Tax Liability for any 
Taxable Year pursuant to Section 4(f) of this Agreement) that would have been 
available to Destec or such Subsidiary if the Destec Group that not been 
included in the Dow Group for the current Taxable Year and all prior Taxable 
Years and all Pro Forma Destec Returns had been actual returns, then Dow 
shall pay to Destec or its Subsidiaries, within 10 days of notification of 
the determination described in this Section 7(b), an amount equal to the 
value such attributes would have had, as described below. Dow's 
determinations pursuant to this Section 7(b) shall be presumptively correct 
and shall be binding on the parties hereto. At Destec's request, the 
calculation of any such amounts shall be verified by a Big Six accounting 
firm jointly selected by Dow and Destec, whose fees and expenses shall be 
shared equally by Dow and Destec, and whose final determination shall be 
final and binding on the parties hereto. For purposes of this Section 7(b), 
tax credits shall be valued on a dollar-for-dollar basis and losses or 
deductions shall be valued at 38 percent of their nominal amount.

     (c) If a Member at any time acquires the assets and properties of 
another Member pursuant to a transaction to which Section 381 of the Code 
applies or otherwise, the acquiring Member shall, from and after the date of 
such acquisition, be responsible for all of the undertakings and obligations 
of such other Member hereunder and shall, from and after such date, be 
entitled to receive any and all

                                     20

<PAGE>

payments that such other Member would be entitled to receive hereunder. 
Provided such other Member ceases to exist solely as a result of such 
transaction, such event shall not, except as expressly provided herein, in 
any way result in any acceleration of the time at which any payments 
hereunder are due to or from such other Member, and, except as expressly 
provided herein to the contrary, all such payments shall be made to or by 
the acquiring Member at the same time or times that such payments would be 
payable to or by such other Member had such other Member continued to exist 
as a Member hereunder.

     8.  ADJUSTMENTS.

     (a) If any adjustment is made with respect to a Taxable Year during 
which Destec or any of its Subsidiaries is a member of the Dow Group to any 
item of income, gain, loss, deduction expense or credit of Destec or any 
Subsidiary of Destec by reason of the filing of an amended Consolidated 
Return (or an amended Combined Return), a claim for refund with respect to 
such Taxable Year or an audit with respect to such Taxable Year by the 
Service (or the applicable state and local taxing authority), the amounts, if 
any, due to or from Destec under this Agreement shall be redetermined by 
taking into account any such adjustment and applying the procedures set 
forth in this Agreement. Dow shall have sole and absolute discretion, but 
after prior good faith consultation with the Tax Director of Destec, to 
determine whether and in what amount an adjustment applies to Destec or any 
of its Subsidiaries. If, as a result of such redetermination, any amounts due 
to or from Destec under this Agreement differ from the amounts previously 
paid, then except as herein provided, payment of such difference together 
with any interest, penalty or addition to tax properly allocated to Destec 
shall be made to Destec or by Destec in the manner provided in Section 9(a) 
as follows: (a) in the case of an adjustment resulting in a credit or refund 
of tax, within 10 calendar days of the date on which such refund or notice 
of such credit is received by Dow or Destec with respect to such adjustment, 
or (b) in the case of an adjustment

                                     21

<PAGE>

resulting in a payment of additional tax, within 10 calendar days of the date 
on which such additional tax is paid. Any interest, penalty or addition to 
tax will be allocated as Dow, in its discretion, deems just and proper in 
view of all applicable circumstances (to the extent practicable, however, 
such allocations shall reflect the amount of interest that the Destec Group 
would have paid on a stand alone basis). Neither acceptance of a Pro Forma 
Destec Return nor failure by Dow to file consistently with such Pro Forma 
Destec Return shall relieve Destec of liability for an adjustment under this 
Section 8(a).

     (b) REFUND OF TAX SHARING PAYMENT. In the event that the Pro Forma 
Destec Return (or the corresponding calculation with respect to the Destec 
Group State and Local Tax Liability) for any Taxable Year reflects a net 
operating loss, net capital loss, Designated Credit, excess tax credit or 
other tax attribute, such attributes (other than Designated Credits that have 
reduced the Destec Group Consolidated Tax Liability pursuant to Section 
4(f)(i) and (ii) and Designated Credits described in section 4(f)(iii), which 
may be carried forward pursuant to Section 4(f)(iii)), may be carried back or 
carried forward, as the case may be, and utilized in calculating the Destec 
Group Consolidated Tax Liability (or the Destec Group State and Local Tax 
Liability) for prior or subsequent Taxable Years in the same manner as such 
attributes would have been carried back or carried forward and deducted if 
the Pro Forma Destec Returns had been actual returns or, in the case of state 
and local tax, under applicable state or local provisions, as such 
provisions would have been applied to a Combined Return, but after taking 
into account any limitation on the use of such attributes imposed pursuant 
to the Code or the Income Tax Regulations (or with respect to a Combined 
Return, applicable state or local provisions). In such case the Destec Group 
Consolidated Tax Liability (or the Destec Group State and Local Tax Liability) 
shall be recomputed for the Taxable Year or Years to which such attributes 
are carried and for any subsequent Taxable Years to take into account such 
attributes, and payments made pursuant to Sections 5 and 6 of this Agreement 
shall be appropriately

                                     22

<PAGE>

adjusted. In the case of any carryback of attributes pursuant to this Section 
8(b), any payment between Dow and Destec required by such adjustment shall be 
paid within 45 days after Completion (or the corresponding date with respect 
to the relevant Combined Return) for the year in which such attribute arises.

     (c) For purposes of Section 8(b), if the Pro Forma Destec Return for a 
Taxable Year reflects a net operating loss, in addition to the carryback 
provisions set forth in Section 8(b), the Destec Group can also carry back 
and recalculate its Destec Group Consolidated Tax Liability for any taxable 
year prior to a Taxable Year that would otherwise be permitted under the Code 
and applicable Income Tax Regulations (assuming the Destec Group had never 
become a Member of the Dow Group), and if such carryback would have resulted 
in a refund of the Destec Group Consolidated Tax Liability for such taxable 
year, and if the net operating loss is reflected in the Dow Group 
Consolidated Return and reduces the Dow Group Consolidated Tax Liability for 
the Taxable Year in which it occurs, Dow will pay Destec the lesser of (a) 
the amount of such refund that Destec would otherwise have received from the 
Service resulting from such carryback, or (b) the amount by which the Dow 
Group Consolidated Tax Liability for the Taxable Year was reduced by the 
reflection of the net operating loss.

     (d) Except as provided in Section 8(a) or 8(b) of this Agreement, Destec 
may not amend a Pro Forma Destec Tax Return for a prior Taxable Year or 
otherwise cause a redetermination of the Destec Group Consolidated Tax 
Liability for a prior Taxable Year. Nothing in this Section 8 shall be 
construed to entitle Destec or any Subsidiary of Destec to receive a double 
benefit or compensation with respect to any attribute.

     9.  REMITTANCES BY AND TO DESTEC.

     (a) Until such time as Dow notifies Destec in writing to the contrary, 
any and all payments that Destec agrees to make hereunder shall be made and

                                     23

<PAGE>

remitted by Destec directly to Dow. Dow shall be responsible for making all 
payments required to be made hereunder to Destec.

     (b) Any payment required to be made hereunder by Destec or Dow that is 
not made on or before the date on which such payment is due under the terms 
of this Agreement shall bear interest at the rate specified from time to time 
pursuant to section 6621(a)(2) of the Code, and the party to whom such 
payment is due shall be entitled to receive interest computed at such rate 
upon the late payment of any such amount which is required at any time to be 
paid hereunder.

     10. CARRYBACKS.

If part or all of an unused consolidated net operating loss or tax credit of 
Destec or one of its Subsidiaries arises in a year in which Destec or such 
Subsidiary is not a Member of the Dow Group and is carried back to a year in 
which Destec or such Subsidiary is a Member of the Dow Group, any refund or 
reduction in tax liability arising from the carryback will be retained by or 
allocated to Dow. Dow shall have no obligation to pay to Destec or its 
Subsidiaries the amount of any refund or credit of federal income tax that 
Dow may receive as a result of such carryback (nor will such occurrence 
affect the amount of compensation, if any, to which Destec or any of its 
Subsidiaries is entitled pursuant to Section 7(b) of this Agreement).

     11. ALLOCATION OF DOW GROUP CONSOLIDATED TAX LIABILITY FOR PURPOSES OF 
DETERMINING EARNINGS AND PROFITS.

     The Dow Group Consolidated Tax Liability for each Taxable Year of the 
Dow Group shall, for purposes of determining the earnings and profits of each 
Member, be allocated among the Members in accordance with the methods 
prescribed in Section 1.1552-1(a)(1) of the Income Tax Regulations. 
Notwithstanding the foregoing, Dow may, in its sole and absolute discretion, 
change the method set forth above to the extent that it is permitted to do so 
by applicable law; provided



                                      24

<PAGE>

further that such change in method is consistently applied to all Members of 
the Dow Group.

     12. DOW CONTROL OF CONDUCT OF AUDITS, LITIGATION, EXPENSES.

     (a) In any audit, conference or other proceeding with the Service or the 
relevant state or local authorities, or in any judicial proceedings 
concerning the determination of the Dow Group Consolidated Return Liability 
or the state or local income tax liability of any consolidated, combined or 
unitary group including Dow or any of its Subsidiaries (other than Destec or 
a Subsidiary of Destec) and Destec (for any of the Subsidiaries of Destec), 
Dow shall have the exclusive right to contest (with the participation of the 
Tax Director of Destec in (a) any examination by the Service at the district 
level or by any state or local authority, or (b) in the preparation and 
submission of any protest brief or other submission to the Service's 
appellate division or in any similar administrative proceeding before any 
state or local authority), compromise or settle any adjustment or deficiency 
proposed, asserted or assessed as a result of such proceeding and to extend 
or refuse to extend the applicable time period for making assessments or 
adjustments. Destec and each Subsidiary of Destec hereby appoints Dow as its 
agent for the purpose of conducting such contest or proposing and concluding 
any such compromise and settlement. Dow shall have control over the 
proceedings, but shall confer in good faith with Destec regarding any proposed 
adjustment bearing on any material liability of Destec pursuant to this 
Agreement. Destec shall support any audit or other examination or judicial or 
administrative proceeding with respect to any Taxable Year, at its own 
expense, in any reasonable way requested by Dow. Nothing herein shall limit 
Dow's discretion to determine whether and in what amount an item arising from 
Destec or any Destec Subsidiary shall be conceded or otherwise compromised 
and whether and in what amount an item results in an adjustment to Destec 
described in Section 8(a);



                                      25

<PAGE>

provided, however, that such decision shall be made only after full and 
complete good faith consultation with the Tax Director of Destec.

     (b) EXPENSES.  Destec shall reimburse Dow for all expenses (including 
without limitation, legal and accounting fees) incurred by Dow in the course 
of proceedings described in this Section 12 to the extent such expenses are 
allocable, in Dow's sole and absolute discretion, but after prior good faith 
consultation with Destec (if requested by the Tax Director of Destec), to 
Destec Group Items.

     13. PARTNERSHIP INTERESTS.

     In connection with any partnership interest for which Destec or a Destec 
Subsidiary is the Tax Matters Partner, Destec shall to the maximum extent 
feasible make elections, use accounting methods, and report positions with 
respect to such partnership interest that are consistent with positions 
reported on the Dow Group's Consolidated Return and report positions on the 
Pro Forma Destec Return that are consistent with those reported for such 
partnership interest on the Dow Group's Consolidated Return. Destec shall 
confer in good faith with Dow in advance regarding any such item which may be 
or could be inconsistent with items on the Dow Group's Consolidated Return.

     14. ADMINISTRATION; RESOLUTION OF DISPUTES.

     The provisions of this Agreement will be administered by Dow. Except as 
otherwise expressly governed by the terms of this Agreement, Dow may use any 
reasonable method in making any computations or allocations hereunder, and 
Dow's calculations will be conclusive unless a written objection is provided 
to Dow within one year of such calculations. If written objection is timely 
made by Destec, the disputed issue (other than disputes described in Section 
4(e) of this Agreement, which disputes shall be governed solely by such 
provision) shall be resolved by a Big Six accounting firm jointly selected by 
Dow and Destec, whose



                                      26

<PAGE>

determination will be conclusive and binding upon the parties and whose fees 
and expenses shall be shared equally by Dow and Destec. Nothing in this 
Section 14 is intended to limit Dow's discretion in making any computations, 
allocations or determinations that may expressly be made under this Agreement 
in Dow's sole and absolute discretion.

     15. ADDITIONAL AGREEMENTS.  In order to permit the exercise of Destec's 
employee stock options outstanding on the date of this Agreement in 
accordance with their terms, and in order to permit Destec to continue to 
issue and sell securities for financing, incentive compensation and other 
purposes, and in connection therewith to avoid the inadvertent exclusion of 
the Destec Group from the Dow Group as a result of a reduction to below 80% of 
Dow's ownership of Destec caused by the exercise of such options or the 
issuance or sale of securities by Destec, Destec and Dow agree as follows:

     (a) SHARE PURCHASE RIGHT.  In the event that, after the Effective Date, 
Destec shall become obligated to, or otherwise undertakes to issue or sell 
additional, unissued or treasury shares, whether by the exercise of options, 
warrants, conversion or exchange rights, or otherwise, and upon completion of 
such issuance or sale (a "Disqualifying Sale") Destec will cease to be a 
Member of the Dow Group, Dow is hereby granted the right to acquire from 
Destec, prior to the completion of the Disqualifying Sale and at the Purchase 
Price Per Share (as defined in subsection (c) below) for the day immediately 
preceding the date of the Destec Notice (as defined in subsection (b) below), 
that number of whole shares of additional, unissued or treasury shares of 
Destec necessary to prevent Dow's ownership from falling below the level 
required to prevent Destec from ceasing to be a Member of the Dow Group. The 
right granted in this Section 15 is a continuing right and may be exercised 
by Dow from time to time during the term of this Agreement as may be 
necessary in order to maintain Destec as a Member of the Dow Group; PROVIDED, 
however, that if at any time Dow shall elect not to 



                                      27
<PAGE>

exercise the rights granted in this Section 15 and permit the issuance or 
sale by Destec of a number of additional, unissued or treasury shares 
sufficient to cause Destec to cease to be a Member of the Dow Group, the 
rights granted in this Section 15 shall immediately terminate.

     (b)  NOTIFICATION PROCEDURES.  Destec agrees to give Dow notice (the 
"Destec Notice") at least ten Business Days prior to the completion (by 
delivery of certificates representing the shares against payment therefor) of 
a Disqualifying Sale in order to permit Dow to exercise its share purchase 
right contained in Section 15.  The Destec Notice shall contain (i) a 
statement of the number of shares to be issued in the Disqualifying Sale (ii) 
a calculation of the number of shares which Dow is entitled to purchase 
pursuant to this Section 15, (iii) a statement of the Purchase Price Per 
Share and the aggregate purchase price required to be paid by Dow for such 
shares, and (iv) a form of Purchase Notice and accompanying letter containing 
the representations required to be made by Dow pursuant to Section 15(d).

     (c)  PURCHASE PRICE PER SHARE.  The Purchase Price Per Share for shares 
of Destec capital stock on any day means the average (mean) of the reported 
"high" and "low" sale prices for such shares as reported in THE WALL STREET 
JOURNAL'S NYSE-Composite Transactions listing for such day (corrected for 
obvious typographical errors), or if such shares are not reported in such 
listing, then the average of the reported "high" and "low" sale prices on the 
largest national securities exchange (based on the aggregate dollar value of 
securities listed) on which such shares are listed or traded, or if such 
shares are not listed or traded on any national securities exchange, then the 
average of the reported "high" and "low" sale prices for such shares in the 
national market system or the over-the-counter market, as applicable, of the 
National Association of Securities Dealers Automated Quotation System, or, if 
such prices shall not be reported thereon, the average between the closing 
bid and asked prices reported by the National

                                     28 
<PAGE>

Quotation Bureau Incorporated, or, in all other cases, the value established 
by the Board of Directors of Destec in good faith.

     (d)  PURCHASE PROCEDURE.  In the event that Dow determines to exercise 
its purchase right contained in Section 15, it shall deliver to Destec prior 
to the expiration of the ten Business Day period referred to in subsection 
15(b) above notice of its election to purchase all, but not less than all, of 
the shares Dow is entitled to purchase under this Section 15 (the "Purchase 
Notice").  The Purchase Notice shall be (i) sent concurrently with payment of 
the Purchase Price Per Share for each share being purchased and (ii) 
accompanied by a letter containing representations by Dow that (A) it 
understands that the Destec shares have not been registered under the 
Securities Act of 1933, as amended, or any state securities law, in reliance 
on exemptions therefrom, (B) it has had access to and an opportunity to 
inspect relevant business, financial and other corporate information and data 
of Destec sufficient to enable it to evaluate the merits and risks of the 
purchase of the Destec shares, (C) persons acting on behalf of Destec have 
made available to it the opportunity to ask questions and receive answers 
regarding the financial condition, results of operation and business affairs 
of Destec, (D) it has such knowledge and experience in financial and business 
matters, particularly with respect to the electric power industry, that it is 
capable of evaluating the merits and risks of the purchase of the Destec 
shares, (E) it is purchasing the Destec shares for its own account, for 
investment purposes and not with a view to, or for offer or sale for Destec 
in connection with, any distribution thereof, and it is not participating in 
any such distribution or the underwriting of any such distributions, (F) it 
understands that the Destec shares must be held until the resale thereof is 
subsequently registered under applicable securities laws, or an exemption 
from registration is available, and (G) it agrees that the stock transfer 
records of Destec will reflect a stop transfer instruction with respect to 
the shares, and that certificates representing the Destec shares will be 
stamped or otherwise imprinted with the following legend:


                                     29

<PAGE>

     THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED 
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER ANY STATE  
     SECURITIES LAW.  THE SHARES HAVE BEEN ACQUIRED FOR INVESTMENT AND 
     MAY NOT BE SOLD OR OFFERED FOR SALE IN THE ABSENCE OF AN EFFECTIVE
     REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
     OR AN OPINION OF COUNSEL TO THE COMPANY THAT SUCH REGISTRATION IS 
     NOT REQUIRED.

     (e)  SPECIAL AGREEMENTS OF DESTEC.  Destec agrees to take all corporate 
action required in order to permit Dow to exercise its continuing right 
contained in this Section 15, including the adoption of resolutions approving 
an amendment or amendments to Destec's certificate of incorporation 
increasing the number of authorized but unissued shares of capital stock to a 
number sufficient to permit the exercise of such right and, in the event that 
any such amendment is required, Destec agrees not to complete the sale or 
issuance of the shares giving rise to Dow's right to exercise its purchase 
right hereunder prior to the approval of the necessary amendment by Destec's 
stockholders and the filing of such amendment with the Secretary of State of 
the State of Delaware.

     (f)  CERTAIN DEFINITIONS.  As used in this agreement, the term "Business 
Day" shall mean a day in the City of Houston, Harris County, Texas, that is 
not a legal holiday or a day on which banking institutions are authorized or 
obligated by law to close.

     16.   INDEMNIFICATION AGAINST JOINT AND SEVERAL LIABILITY.

     Except as may be expressly provided otherwise in this Agreement, Dow 
shall be liable for, and agrees to defend, hold harmless and indemnify the 
Destec Group from and against, any and all taxes (and any interest, penalties 
and similar amounts relating thereto) of the Dow Group (other than the Destec 
Group),


                                     30

<PAGE>

including, but not limited to, any such taxes (and any interest, penalties 
and similar amounts relating thereto) for which the Destec Group (or any 
Member thereof) is or may be or become liable for under any successor or 
transferee liability law or other similar law or under Section 1.1502-6 or 
1.1502-78(b)(2) of the Income Tax Regulations or any similar provision under 
any applicable foreign, state, or local law.

     17.  INTERPRETATION.

     This Agreement is intended to provide for the calculation and allocation 
of certain federal and state and local income tax liabilities between the Dow 
Group (other than Destec and its Subsidiaries) and the Destec Group, and any 
situation or circumstance concerning such calculation and allocation that is 
not specifically contemplated hereby or provided for herein shall be dealt 
with in a manner consistent with the underlying principles of calculation and 
allocation in this Agreement.

     18.  EFFECT OF AGREEMENT.

     This Agreement shall determine the liability of Dow and Destec as to the

reporting purposes or for any other purpose.

     19.  TERM.
  
     This Agreement will apply to Taxable Years ending after the Effective 
Date and all subsequent Taxable Years, unless Dow and Destec agree in writing 
to terminate this Agreement.  Notwithstanding such termination, this 
Agreement will continue in effect with respect to any payment or refunds due 
for all Taxable Years prior to termination.  Destec or any Subsidiary of 
Destec that leaves the Dow Group will be bound by this Agreement. The failure 
of one or more parties



                                     31


<PAGE>

hereto to qualify for inclusion in the Consolidated Return filed by Dow will 
not operate to terminate this Agreement with respect to the other parties as 
long as two or more parties hereto continue to so qualify.

     20. ASSIGNMENT.

     Rights and obligations under this Agreement will not be assignable by 
any party without the prior written consent of the other parties.

     21. CONFIDENTIALITY.

     Dow, Destec and the Subsidiaries of Destec agree that any information 
furnished among one another pursuant to this Agreement is confidential and, 
except as and to the extent required during the course of the preparation of 
returns or the conduct of an audit or litigation, shall not be disclosed to 
other persons.

     22. DOCUMENTATION.

     All material, including but not limited to, returns, supporting 
schedules, work papers, correspondence, and other documents relating to the 
Consolidated Return and any Combined Returns filed for a Taxable Year subject 
to this Agreement will be made available to any party to the Agreement during 
regular business hours for a minimum period equal to applicable federal and 
state record retention requirements (or the applicable statute of limitations 
period).

     23. ADDITIONAL MEMBERS.

     The parties hereto specifically recognize that from time to time other 
Subsidiaries of Dow and Destec may become or become again Members of the Dow 
Group and hereby agree that this Agreement shall be deemed to have been 
adopted and affirmed, or readopted and reaffirmed, by such Subsidiary. Dow and



                                      32

<PAGE>

Destec shall, upon the written request of the other, cause any of their 
respective Subsidiaries formally to ratify and execute this Agreement.

     24. TAX LAW CHANGES.

     Any alteration, modification, addition, deletion, or other change in the 
Code or the Income Tax Regulations (or the applicable state and local tax 
provisions) will automatically be applicable to this Agreement when changed.

     25. SUCCESSORS AND ASSIGNS.

     This Agreement will bind and inure to the benefit of the respective 
successors and assigns of the parties hereto; but no assignment will relieve 
any party of its obligations hereunder without the written consent of the 
other parties.

     26. COUNTERPARTS.

     This Agreement may be executed in two or more counterparts, each of 
which shall be deemed to be an original, but all of which together shall 
constitute one and the same instrument.

     27. HEADINGS.

     The headings in this Agreement are inserted for convenience only and 
shall not constitute a part hereof or affect the interpretation of this 
Agreement.

     28. SEVERABILITY.

     If any provision of this Agreement is held to be unenforceable for any 
reason, it shall be adjusted rather than voided, if possible, in order to 
achieve the intent of the parties to the maximum extent practicable. In any 
event, all other provisions of this Agreement shall be deemed valid, binding 
and enforceable to their full extent.

               FIRST AMENDMENT TO THE TAX SHARING AGREEMENT


      This FIRST AMENDMENT TO THE TAX SHARING AGREEMENT (the "Amendment") is 
entered into as of the 17th day of February, 1997, by and among THE DOW 
CHEMICAL COMPANY, a Delaware corporation ("Dow"), as Common Parent, on behalf 
of itself and the other members of the Dow Group (other than any member of 
the Destec Group), and DESTEC ENERGY, INC., a Delaware corporation 
("Destec"), on behalf of itself and the other members of the Destec Group.

      WHEREAS, Dow and Destec entered into a Tax Sharing Agreement, effective 
May 15, 1996 (the "Agreement");

      WHEREAS, Dow has agreed to sell the Destec stock it owns pursuant to 
the Agreement and Plan of Merger, dated February 17, 1997, among Dow, Destec, 
NGC Corporation, a Delaware corporation ("NGC"), and NGC Acquisition 
Corporation II, a Delaware corporation (the "Acquisition Agreement");

      WHEREAS, pursuant to the Acquisition Agreement, Dow and NGC intend to 
make a joint election for Destec (and all U.S. corporations that are 
subsidiaries of Destec) under Section 338(h)(10) of the Code and NGC or a 
successor of NGC intends to make elections under Section 338(g) of the Code 
for certain non-U.S. direct or indirect subsidiaries;

      WHEREAS, the corporations which comprise the Destec Group will no 
longer be Members of the Dow Group after the date of the Effective Time as 
defined in the Acquisition Agreement, and therefore Dow and Destec deem it 
necessary to amend the Agreement in certain respects; and

      NOW THEREFORE, in consideration of the premises and of the mutual 
covenants and agreements contained in this Amendment, the parties agree as 
follows:

      Paragraph 1.  Capitalized terms used in this Amendment and not 
otherwise defined in this Amendment have the meaning ascribed to such terms 
in the Agreement.

      Paragraph 2.  Section 1(aa) of the Agreement shall be amended by 
changing clause (b) thereof by deleting "the Effective Date" and inserting in 
place thereof "January 1, 1996".

      Paragraph 3.  Section 5 of the Agreement shall be amended by adding at 
the end thereof the following paragraph (d):

            (d)  Lignite. In determining the Destec Group Consolidated Tax
      Liability and the Destec Group State and Local Tax Liability for
      the Final Taxable Year, the Pro Forma Destec Return shall exclude
      any amount of gain resulting from the exercise by Dow of its rights
      to purchase lignite containing properties from Destec pursuant to
      the First Amended Lease Agreement dated January 1, 1990 between
      Destec Ventures, Inc., as lessor, and Dow, as lessee.

      Paragraph 4.  Section 5 of the Agreement shall be amended by adding at 
the end thereof the following paragraph (e):
<PAGE>

            (e)  Payments With Respect To Final Taxable Year. The Destec
      Group Consolidated Tax Liability and the Destec Group State and
      Local Tax Liability for the Final Taxable Year shall be calculated
      assuming no elections under Section 338(h)(10) or 338(g) of the
      Code will be made. For purposes of calculating the amount of any
      payment from Dow to Destec pursuant to Section 7(b) of this
      Agreement, Destec shall be treated as ceasing to be a Member of the
      Dow Group at the end of the Final Taxable Year pursuant to a stock
      sale and no consolidated loss or credit carryovers as of the end of
      the Final Taxable Year shall be considered allocable to Destec
      under the Consolidated Return Regulations, and Dow will be treated
      as having utilized all items of loss, deduction, credit or similar
      tax attributes of the Destec Group in determining the Dow Group
      Consolidated Tax Liability and the Dow Group State and Local Tax
      Liability for the Final Taxable Year. At the Effective Time under
      the Acquisition Agreement, Dow shall pay Destec $10 million, which
      amount shall be netted or offset against any amount owed by Dow to
      Destec with respect to the Final Taxable Year pursuant to the
      Agreement. If by January 31, 1999, $10 million exceeds the
      cumulative amount owed by Dow to Destec pursuant to the Tax Sharing
      Agreement with respect to the Final Taxable Year, then Destec shall
      refund to Dow the amount of such excess within 10 business days.

      Paragraph 5.  Section 8 of the Agreement shall be amended by adding at 
the end thereof the following paragraph (e):

            (e)  If an adjustment described in Section 8(a) gives rise to
      an obligation of Destec to make a payment to Dow pursuant to this
      Section 8, and as a result of such adjustment Dow receives a refund
      of tax or a reduction of its liability for taxes (including by
      reason of a reduction of the gain recognized by the Dow Group as a
      result of an election with respect to Destec under Section
      338(h)(10) of the Code), the amount of such payment from Destec to
      Dow shall be reduced by the amount of such refund (including any
      interest or penalties included therein) or such reduction,
      provided, however, that if such refund is received or such
      reduction is taken into account after the date of such payment,
      Destec shall pay the full amount of such payment to Dow, and Dow
      shall pay an amount equal to such refund or the amount of such
      reduction to Destec within 10 business days after the date such
      refund is received or such reduction is taken into account.

      Paragraph 6.  Section 15 of the Agreement is hereby deleted.

      Paragraph 7.  Section 19 of the Agreement shall be amended by inserting 
the following sentence after the first sentence:

      This Agreement shall not affect the application of the Tax Agreement 
      between Dow and Destec effective September 25, 1990 and the Tax 
      Agreement between Dow and Destec effective January 5, 1992 with 
      respect to taxable years or portions thereof that are not Taxable Years.
<PAGE>

      Paragraph 8.  All provisions of the Agreement remain in full force and 
effect, except (a) as modified by this Amendment, and (b) to the extent that 
Section 12 or 16 of the Agreement conflicts with any of the provisions of 
Section 6.14 of the Acquisition Agreement, in which case the provisions of 
Section 6.14 of the Acquisition Agreement shall govern.

      Paragraph 9.  Section 16 of the Agreement shall be amended by deleting 
the words "of the Dow Group (other than the Destec Group)" and adding in its 
place the words "due with respect to a Consolidated Return or a Combined 
Return".

      Paragraph 10.  Section 5(a) of the Agreement shall be amended by 
deleting in the first sentence thereof the words "and the Destec Group State 
and Local Tax Liability".

      Paragraph 11.  This Amendment shall be governed by and construed in 
accordance with the laws of the State of Delaware, U.S.A.

      Paragraph 12.  This Amendment shall be effective as of the Effective 
Time under the Acquisition Agreement.

      Paragraph 13.  This Amendment may be executed in any number of 
counterparts, each of which shall be deemed an original, and said 
counterparts shall constitute one and the same instrument.

      IN WITNESS WHEREOF, the parties have caused this Amendment to be duly 
executed as of the date first set forth above.

Agreement and Plan of Merger, dated February 17, 1997, by and among Destec, 
Dow, NGC Corporation and NGC Acquisition Corporation II.

     1.5  "Energy Generation Facility" means a new, or replacement of 
substantially all of a, facility designed and constructed to generate at

     1.7  "TDCC" has the meaning stated in the preamble.

2.   TERM

     The term and effectiveness of this Agreement begin at the Effective Time

3.   NOTIFICATION AND INVITATION TO BID

     3.1  During the term of this Agreement, Dow will include Destec in the Dow

     3.3  In the event that Dow does not provide notification and an invitation
to bid (however captioned at the time) to Destec according to Section 3.1, Dow 
will pay Destec the amount of damages which Destec shows it suffered up to a

damages which Destec may claim pursuant to Section 3.3 and shall not provide 
any obligation on the part of Dow with respect to any entity other than Destec
pursuant to Section 3.3.

"First Amendment"), effective as of December 31, 1996 (the "Effective
Date") by and between THE DOW CHEMICAL COMPANY ("Dow") and DESTEC ENERGY,
INC. ("Destec").

                                RECITALS:

      WHEREAS, Dow and Destec entered into the Research & Development
Agreement, effective as of March 1, 1990 (the "Agreement"), whereby
Destec engaged Dow to provide certain research and development services
with respect to intellectual property relating to the gasification of

Agreement:

      1.  All terms, covenants, obligations and conditions in the

          31, 1997, unless otherwise agreed in writing by the parties.

      3.  Sections 4.1, 4.2 and 4.3 are deleted in their entirety and

      6.  Section 9.1 is hereby deleted in its entirety and replaced by

          9.1 (a)  Destec will reimburse Dow for (i) a fee of One Hundred
          Twenty-Five Thousand and No/100 Dollars ($125,000.00) per man
          year of effort for services of each of the Designated Dow R&D
          Person(s), such fee to be prorated, (ii) reasonable travel
          expenses incurred by Dow personnel, including the Designated
          Dow R&D Person(s), at Destec's request, (iii) the fully
          absorbed costs plus a five percent (5%) adder for any services
          provided by Dow to Destec other than the services of the
          Designated Dow R&D Person(s) (e.g. analytical services,
          computer services), and (iv) all reasonable out-of-pocket
          expenses incurred for patent filing fees, prosecution costs and
          maintenance fees associated with any patent applications filed
          or patents obtained by Dow under Section 7 of the Agreement on
          behalf of Destec. Reimbursement by Destec of costs incurred by
          Dow under Section 7 of the Agreement in excess of 110% of the
          agreed upon patent obtention and maintenance fees shall require
          the advance written consent of Destec.

          (b)  In addition to the foregoing, Destec shall pay the
          reasonable relocation expenses of any Designated Dow R&D
          Person(s), for which relocation is required in order to
          effectuate the terms of Section 5.5. In the event that any
          change in location is at the request of Dow, then Dow shall be
          responsible for the relocation expenses of such Designated Dow
          R&D Person(s). Upon the termination of this Agreement, any
          relocation expenses of the Designated Dow R&D Person(s) located
          at Destec's Terre Haute facility, which are incurred due to
          such termination, are to be the responsibility of Dow.

      7.  Section 9.3 is amended by deleting the phrase "the Dow Louisiana
Division in Plaquemine, Louisiana" from the 3rd sentence, and
substituting the phrase "Dow's offices located in Midland, Michigan" in
place thereof.

      8.  With respect to any Destec employees currently working at the
Wabash Project as of February 17, 1997, who are subsequently hired by
Dow, Dow will make such individuals available to Destec under the terms
of this Agreement, at Destec's request, at fully absorbed cost plus 30%
until December 31, 1998.


      IN WITNESS WHEREOF, the parties have executed this First Amendment
as of the day and year first above written.

          (2)  The Participant and Subcontractor shall have:

               (i)    The right to withhold Proprietary Data in accordance with
                      the provisions of this clause; and

               (ii)   The right to use for their private purposes, subject to
                      patent, security, or other provisions of this Subcontract,
                      Contract Data first produced in the performance of this
                      Subcontract, provided the data requirements of this
                      Subcontract have been met as of the date of the private
                      use of such date.  The Subcontractor agrees that to the
                      extent it receives or is given access to Proprietary Data
                      or other technical, business, or financial data in the
                      form of recorded information from DOE or a DOE Contractor,
                      including that of Participant, or Subcontractor, the
                      Subcontractor shall treat such data in accordance with any
                      restrictive legend contained thereon unless use is

     (c)  Copyrighted material.

          (1)  The Subcontractor shall not, without prior written authorization
               of the Patent Counsel, establish a claim to statutory copyright
               in any Contract Data first produced in the performance of this
               Subcontract.  To the extent such authorization is granted, the
               Government reserves for itself and others acting on its behalf a
               royalty-free, nonexclusive, irrevocable, worldwide license for
               Governmental purposes to publish, distribute, translate,
               duplicate, exhibit, and perform any such data copyrighted by the
               Subcontractor.  To the extent such authorization is granted, the

                                        6

<PAGE>

               Participant is granted a royalty-free, nonexclusive, irrevocable,
               worldwide, transferable license to incorporate and utilize any
               such data copyrighted by the subcontractor in the CGCC

               copyrighted by others, without first granting or obtaining at no
               cost a license therein for the benefit of the Government and the
               Participant of the same scope as set forth in Paragraph (c)(1)
               above.  If such royalty-free licenses are unavailable and the
               Subcontractor nevertheless determines that such copyrighted
               material must be included in the Technical Data to be delivered,
               rather than merely incorporated therein by reference, the
               Subcontractor shall obtain the written authorization of the
               Contracting Officer to include such copyrighted material in the
               Technical Data prior to its delivery.

          (3)  The Subcontractor agrees that upon written application by the DOE
               it will grant to the extent practicable a non-exclusive license
               to responsible third parties in any copyrighted work that is
               utilized, tested or embodied by the Subcontractor in the
               performance of work under this Subcontract to practice the CGCC
               Technology system which is the subject of the Cooperative
               Agreement on terms and conditions which are reasonable under the
               circumstances.

     (d)  Lower Tier Subcontracting.  It is the responsibility of the
          Subcontractor to obtain from the contractors and lower tier
          subcontractors Technical Data and rights therein, on behalf of the
          Government and the Participant, necessary to fulfill the
          Subcontractor's obligations to the Government and the Participant with
          respect to such data.  In the event of refusal by a lower tier
          subcontractor to accept a clause affording the Government and the
          Participant such rights, the Subcontractor shall:

          (1)  Promptly submit written notice to the Participant and the
               Contracting Officer of the Cooperative Agreement setting forth
               reasons for the lower tier subcontractor refusal and other
               pertinent information which may expedite disposition of the
               matter; and

                                        7

<PAGE>

          (2)  Not proceed with the Subcontract without written authorization of
               the Contracting Officer.

          (3)  As used in this Rights in Technical Data clause, the term
               Contractor or Subcontractor includes any person or entity
               responsible for fulfilling the Participant's obligations to the
               Government with respect to technical data.

     (e)  Withholding of Proprietary Data.  Notwithstanding the inclusion of the
          additional Technical Data Requirements Clause in this Subcontract or
          any provision of this Subcontract specifying the delivery of Technical
          Data, the Subcontractor may withhold Proprietary Data from delivery,
          provided that the Subcontractor furnishes in lieu of any such
          Proprietary Data so withheld Technical Data disclosing the source,
          size, configuration, mating and attachment characteristics, functional
          characteristics, and performance requirements ("Form, Fit, and
          Function" data, e.g., specification control drawings, catalog sheets,
          envelope drawings, etc.), or a general description of such Proprietary
          Data where "Form, Fit, and Function" data are not applicable.  The
          Government shall acquire no rights to any Proprietary Data so withheld

          at all reasonable times up to 3 years after final payment under the
          Cooperative Agreement, may inspect at the Subcontractor's facility any
          Proprietary Data withheld under Paragraph (e) for the purpose of
          verifying that such data properly fell within the withholding
          provisions of Paragraph (e) or for evaluating work performance.

     (g)  Limited rights in Proprietary Data.  Except as may be otherwise
          specified in this Subcontract as Technical Data which are not subject
          to this paragraph, the Subcontractor shall, upon written request from
          the Contracting Officer at any time prior to 3 years after final
          payment under this Cooperative Agreement, promptly deliver to the
          Government any "Proprietary Data" withheld pursuant to paragraph (e)

                      mutual agreement of the other party, any data first
                      produced in the performance of this Subcontract by the
                      other party's employees.

               (2)    Any such claimed Protected Clean Coal Technology Data will
                      be clearly marked as "Protected Clean Coal Technology
                      Data", will be treated as such, and, except as otherwise
                      provided herein, will not be published, disseminated or
                      disclosed to others outside the Government by the
                      Government for a period, as approved by DOE, of up to 5

          SECTION 8.01  TERMINATION.  This Agreement may be terminated at any
time prior to the Closing Date as follows, and in no other manner:

          (a)  by mutual consent of FPC, Guarantor, and Tiger Bay;

          (b)  after January 21, 1997, or such later date for obtaining Board
Approval as has been mutually agreed to by FPC, Tiger Bay and Destec Energy,
Inc., by written notice from any party to the others, if the Board Approval has

          (c)  prior to February 1, 1997, by written notice from FPC to Tiger
Bay that FPC's due diligence with respect to the Assets (except with respect to
the Plant gas turbine compressor) has been completed and the results were
unsatisfactory to it, and FPC is therefore terminating this Agreement;

          (d)  on or prior to April 30, 1997, by written notice from FPC to
Tiger Bay that:

               (i)    FPC's investigation of the Plant gas turbine compressor
     conducted during the period of the outage of the Plant scheduled to begin
     on March 15, 1997 (the "Scheduled Outage") has been completed; provided,
     however, that if FPC requests that Tiger Bay open the compressor casing in
     connection with such investigation, Tiger Bay shall do so and (A) FPC shall
     reimburse Tiger Bay for all costs and expenses incurred by Tiger Bay to
     open and close the compressor casing within twenty days after receipt of
     Tiger Bay's invoice therefor, and (B) for purposes of the capacity factor
     calculations pursuant to the PPAs, Guarantor shall exclude all the hours,
     if any, by which the Scheduled Outage was extended due to the opening and
     closing of the compressor casing at FPC's request; and

               (ii)   in the written opinion of FPC's professional engineer
     performing or supervising such investigation rendered in good faith (the
     "Engineering Opinion"), based on General Electric approved repair criteria
     and performance versus aging data, such investigation has revealed that the
     mechanical integrity of the compressor is compromised and/or that a
     material loss of performance has resulted or will result in excess of that
     which is to be expected from normal aging, unless Tiger Bay within ten days
     after receipt of such notice and the Engineering Opinion shall have either
     (i) offered in writing to repair or replace such compressor at no
     additional cost to FPC, or (ii) shall have given FPC written notice that
     Tiger Bay disputes the conclusion(s) reached in such Engineering Opinion.
     In the event that Tiger Bay disputes the Engineering Opinion and such
     dispute is not resolved by good faith

                                      -21-

<PAGE>

     negotiations between FPC and Tiger Bay within thirty days after FPC's
     receipt of written notice of such dispute, termination hereunder shall
     become effective at the end of such thirty-day period.

have occurred on or before July 1, 1997 (or such later date as may have been
agreed upon in writing by the parties); provided, however that if (i) by July 1,
1997 the FPSC has issued an order approving the transactions contemplated by
this Agreement satisfactory to FPC and Guarantor in accordance with SECTIONS
6.01(c)(ii) and 6.02(c)(ii) and no party has filed an appeal therefrom, but the
time period(s) for filing any such appeal (the "Appeal Period") shall not have
expired, and (ii) all conditions in SECTION 6.02 except SECTION 6.02(c)(ii) have
been fulfilled or waived in accordance therewith, then Tiger Bay may exercise
its right to terminate this Agreement pursuant to this SECTION 8.01(e) only if
an appeal of such FPSC order is filed during the Appeal Period.

          (f)  by any party by notice to the others, if a final non-appealable
judgment has been entered against such party or any of its Affiliates
restraining, prohibiting or declaring illegal the transactions contemplated
hereby; or

          (g)  by a non-defaulting party giving written notice to a defaulting
party provided that the non-defaulting party shall have previously given the
defaulting party written notice specifying the nature of the default and thirty
days have passed since such notice was given and the default has not been cured
or waived. A party shall be in default under this Agreement, and thereby a
defaulting party, in the event that (i) any representation or warranty made by
such party in this Agreement shall prove to be false or misleading in any
material respect, (ii) such party fails to perform any covenant set forth in
this Agreement, or (iii) such party fails to timely perform or satisfy any
material obligation set forth in this Agreement to be performed or satisfied by
it.

          (h)  by written notice from any party to the others, if the FPSC
issues an order denying approval of the transaction envisioned by this
Agreement, or if the FPSC fails to issue an order in accordance with SECTIONS
6.01(c)(ii) and 6.02(c)(ii) on or before July 1, 1997; provided, however, that
if by July 1, 1997 the FPSC has issued an order approving the transactions
contemplated by this Agreement satisfactory to FPC and Guarantor in accordance
with SECTIONS 6.01(c)(ii) and 6.02(c)(ii) and no party has filed an appeal
therefrom, but the Appeal Period shall not have expired, then a party may
exercise its right to terminate this Agreement pursuant to this SECTION 8.01(h)
only if an appeal of such FPSC order is filed during such Appeal Period.

          SECTION 8.02  LIMITATION ON RIGHT TO TERMINATE; EFFECT OF TERMINATION.
A party shall not be allowed to exercise any right of termination pursuant to
SECTION 8.01 if the event giving rise to the termination right shall be due to
the failure of such party or its Affiliate to perform or observe in any material
respect any of the covenants set forth herein to be performed or observed by
such party of its Affiliate; provided that SECTIONS 4.01(i), 4.02(f), 5.01(f),
5.02(c), 5.02(d), 5.03, 8.01(d)(i), 8.02 and 9.09 shall survive any such
termination.

                               DESTEC ENERGY, INC.
                         EMPLOYEES' STOCK PURCHASE PLAN


     The purpose of the Destec Energy, Inc. (the "Company") Employees' Stock
Purchase Plan (the "Plan") is to provide eligible employees with an opportunity
to purchase shares of common stock, par value $.01 ("Common Stock"), of the
Company at a discount from the prevailing stock market price through a payroll
deduction system.

     1.   IMPLEMENTATION OF PLAN.  The Board of Directors of the Company (the
"Board") may, pursuant to the terms hereof, make available to all eligible
employees the opportunity to purchase shares of Common Stock at a discount
through a payroll deduction system. Each year the Board shall determine whether
it will make the Plan available to eligible employees (a "Plan Year") and will
offer Common Stock for subscription by all eligible employees pursuant to the
terms of this Plan.

     2.   ELIGIBLE EMPLOYEES.  The Plan will be made available to employees who
are full-time U.S. or non-U.S. employees whose normal work week is twenty hours
or more and who are on the payroll of the Company or any corporation or
partnership in which the Company owns directly or indirectly ninety percent or
more of the voting power of such entity. Employees under majority age may
subscribe under the Plan if they meet the other requirements outlined above. An
eligible employee who accepts an offer of subscription for shares of Common
Stock under the Plan shall be referred to herein as a "Subscriber."

     3.   ADMINISTRATION AND INTERPRETATION.  The Plan shall become effective as
of the date of its adoption by resolution of the Board and shall remain in
effect thereafter, unless terminated by the Company. Deloitte & Touche, L.L.P.,
or any successor determined by the Vice President of Human Resources, will
administer the Plan ("Third Party Plan Administrator") with the assistance of
the Vice President of Human Resources and payroll personnel of the Company. The
Vice President of Human Resources shall supervise the administration and
enforcement of the Plan according to its terms and shall have all powers
necessary to accomplish these purposes and discharge the duties imposed hereby,
including, but not limited to, the power to (i) construe and interpret the Plan,
(ii) determine all questions of eligibility, and (iii) compute the amount and
determine the manner and time of payment of all benefits under the Plan. The
Vice President of Human Resources (or his designee's) interpretation of any
provision of the Plan will be final and binding upon all parties concerned
unless otherwise determined by the Board.

     4.   STOCK SUBJECT TO PLAN.  There is hereby established a Stock Purchase
Plan Reserve (the "Reserve"), to which shall be allocated 500,000 shares of
Common Stock. Upon the sale of shares of Common Stock pursuant to this Plan, the
Reserve shall be reduced by the number of shares so sold. Sales hereunder may be
made from authorized but unissued shares or from shares reacquired by the
Company.

                                      -15-
<PAGE>

     5.   PARTICIPATION AND DURATION OF THE OFFER.  Participation in the Plan is
completely voluntary. In any Plan Year, the Board shall advise eligible
employees in writing of the terms of the offer of subscription, including the
total number of shares of Common Stock available during the Plan Year, the
purchase price of the shares, any other terms, conditions and restrictions
relating thereto, and that such employee shall have a minimum of twenty (20)
days from the date of the writing to accept such offer of subscription in the
manner set forth in the offer. The Board may, in the exercise of its discretion,
extend the term of the offer of subscription.

     6.   THE PURCHASE PRICE.  The purchase price of the shares of Common Stock
being offered under the Plan shall be determined by the resolution of the Board
designating a Plan Year and will be based on a discount from the market price
for the Common Stock over a ten day period in the month immediately preceding
the designation of the Plan Year (the "Plan Price"). In each Plan Year, the
Board shall also designate a date for the determination of the Market Price for
the Common Stock (the "Market Price Date"). The Market Price shall be the
average of the high and low trading prices of the Company's Common Stock as
reported in THE WALL STREET JOURNAL on the Market Price Date. If on the Market
Price Date, the Market Price is less than the Plan Price, the purchase price to
Subscribers under subscriptions still in effect under the Plan at the Plan
Completion Date, as defined below, shall be the Market Price rather than the
Plan Price. In that event, any amount by which the total withheld from the pay
of each Subscriber still participating in the Plan exceeds the total Market
Price of the shares for which his or her subscription is then in effect, shall
be refunded to the Subscriber.

     7.   NUMBER OF SHARES WHICH AN EMPLOYEE MAY PURCHASE.  The Board may set a
minimum subscription which will be accepted for purchase of shares of Common
Stock. No employee may enter into a subscription for shares of Common Stock
having a total purchase price (based on the Plan Price) in excess of ten percent
of such employee's gross annual salary. For this purpose, "annual salary"
consists of regular base pay only and does not include any overtime pay, cash
awards or award and option plan compensation. The Board shall set the date for
determination of any eligible employee's annual salary and the size of an
eligible employee's permissible subscription in the Plan Year.

     8.   PRORATION IN THE EVENT OF OVERSUBSCRIPTION.  The number of shares of
Common Stock which any individual employee may purchase pursuant to the Plan in
any Plan Year may be reduced in the unlikely event that the aggregate number of
shares that are purchased by all Subscribers in the Plan Year exceeds the number
of shares reserved by the Board for purposes of the Plan during a Plan Year.
Such reductions, if required, will be accomplished by prorating the shares
available for such Plan Year among the subscriptions received.

                                      -16-

     9.   METHOD OF PAYMENT.

          (a)  PAYROLL DEDUCTIONS.  Subject to a Subscriber's right to
     prepayment as described in Paragraph 10 below, subscriptions will be
     payable by means of payroll deductions on an after-tax basis only. No
     Subscriber may satisfy his or her subscription by the method of a "lump
     sum" of cash at the commencement of any Plan Year.

          During any Plan Year, the Board shall designate the dates on which
     payroll deductions pursuant to the Plan will begin (Plan Year Commencement
     Date") and end ("Plan Year Completion Date"). Each Subscriber will
     authorize such payroll deductions during the applicable period by executing
     an authorization form in the time and manner determined by the Company, and
     such amounts will be deducted in conformity with the Company's payroll
     deduction schedule. The amount of deduction necessary for the purchase of
     Common Stock by each Subscriber shall be determined by the Third Party Plan
     Administrator. If a Subscriber misses any payment because of being
     temporarily off the payroll and does not make up such payments, he or she
     shall be required to make, on or before the Plan Year Completion Date, one
     of the elections listed under Paragraph 12 below. Otherwise the Company
     shall deliver the shares of Common Stock paid for up to that time (based on
     the purchase price as set forth in Paragraph 6) and refund in cash any
     excess remaining out of the amount deducted.

          (b)  PAYMENT TERMS APPLICABLE TO EMPLOYEES OUTSIDE OF THE UNITED
     STATES.  Subscribers residing outside the United States during any portion
     of a Plan Year shall pay for their subscriptions by payroll deduction in
     the currency in which they are paid. On the first day of each calendar
     month during a Plan Year payment period, the Human Resources Department of
     the Company (the "Human Resources Department") will calculate a new
     conversion rate for converting the applicable currencies to U.S. dollars
     based on the prevailing rates of exchange. Such conversion rates will be
     used to determine the amount deducted from Subscribers' pay that month,
     sufficient for their individual subscriptions based on the Plan Price. If a
     subscription is reduced or canceled, or if the applicable purchase price is
     the Market Price on the Plan Year Completion Date, any refund due the
     Subscriber shall be paid in the currency in which the Subscriber is paid,
     based on the then current conversion rate.

     10.  PREPAYMENT.  The Board during a Plan Year shall set a date on and 
after which a Subscriber may prepay, without penalty, the entire balance of 
his or her subscription amount (the "Prepayment Date"). No prepayments will 
be accepted before the Prepayment Date. Any such prepayment shall be based 
upon the Plan Price, shall be final and shall not thereafter benefit from any 
terms of the Plan or any Plan Year with respect to the Market Price.

     11.  CANCELLATION OR REDUCTION OF RIGHT TO PURCHASE.  At any time before
final payment for shares of the Common Stock is completed (by payroll deduction,
prepayment or both) any Subscriber, other than an employee who is deemed to be
an affiliate of the Company under Paragraph 16, may cancel his or her
subscription for a Plan Year in its entirety or, once and once only, reduce (but
not increase) such subscription to a lesser number of shares of Common Stock
which shall not be less

                                      -17-

<PAGE>

than ten shares. If a Subscriber cancels his or her subscription in any Plan
Year in its entirety, he or she shall receive a cash refund of the entire amount
deducted for his or her subscription up to the time of cancellation. If a
Subscriber reduces his or her subscription in a Plan Year and if the sum of
prior deductions equals or exceeds the total purchase price (based on the Plan
Price) of the reduced subscription, such Subscriber may instruct the Third Party
Plan Administrator to reduce the number of shares of Common Stock for which he
or she has subscribed and to refund any excess of the prior deductions over the
purchase price of the reduced subscription. If the amount of prior deductions is
less than the total purchase price (based on the Plan Price) of the reduced
subscription, the Subscriber may:

               (1)       beginning on the Prepayment Date, immediately pay the
               new unpaid balance and instruct the Third Party Plan
               Administrator to issue the reduced number of shares of Common
               Stock;

               (2)       leave the amount previously deducted with the Company
               and instruct the Third Party Plan Administrator to reduce future
               deductions in proportion to the subscription reduction; or

               (3)       instruct the Third Party Plan Administrator to refund
               deductions previously made for the number of shares by which the
               subscription is reduced and to reduce the amount of future
               deductions to that necessary to pay for the reduced subscription.

     All elections concerning the cancellation or reduction of subscriptions in
a Plan Year shall be made on appropriate forms to be provided by the Third Party
Plan Administrator. Any cancellation or reduction of a subscription or any
prepayment in connection with a reduction of a subscription shall be final and
shall not thereafter benefit from any terms of the Plan or any Plan Year with
respect to the Market Price. All repayments and cash refunds shall be paid
without interest.

     12.  RETIREMENT, LONG-TERM DISABILITY, ENTRY INTO MILITARY SERVICE OR
DEATH.  If during the administration of any Plan Year, a Subscriber retires
under the Company's retirement plan, becomes a participant of a long-term
disability plan maintained by the Company, enters military service or dies, such
Subscriber or his or her executor, administrator or heirs, as the case may be,
shall have the following four options:

               (1)       to receive delivery of the shares of Common Stock paid
               for up to that time (based on the Plan Price) if ten or more
               shares have been paid for, and to receive in cash any excess
               remaining out of the amount deducted;

               (2)       to receive a lesser number of shares (at least ten
               shares) of Common Stock (based on the Plan Price) and a refund of
               the balance in cash;

               (3)       to receive a cash refund of the entire amount
               previously deducted; or

                                      -18-

<PAGE>

               (4)       to pay up the balance of his or her subscription in
               full and receive delivery of the total number of shares of Common
               Stock paid for by him or her (based on the Plan Price).

     Such options by a retired or disabled Subscriber, a Subscriber who has
entered the military service, or on behalf of a deceased Subscriber must be
exercised not later than the Plan Year Completion Date. In the event no election
is made by the Plan Year Completion Date, the Company shall deliver the shares
of Common Stock paid for up to that time (based on the purchase price as set
forth in Paragraph 6) and refund in cash any excess amount that was deducted.
All elections with respect to the options available to Subscribers under the
Plan who retire, become disabled or who enter the military service or on behalf
of deceased Subscribers shall be made on appropriate forms, to be provided by
the Third Party Plan Administrator. Any prepayment shall be final and shall not
thereafter benefit from any terms of the Plan with respect to the Market Price.

     13.  SEPARATION FROM EMPLOYMENT.  If a Subscriber for shares of Common
Stock during a Plan Year leaves the employment of the Company or a Company
subsidiary (except in the case of transfer from one of such companies to another
in which case there will be no change, or except in cases of retirement, long-
term disability, entry into military service or death, which latter four cases
are governed by Paragraph 12, or except if such termination of employment is the
result of the Company closing a facility, which case is governed by Paragraph
14), such departing Subscriber shall at that time have the first three options
set forth in Paragraph 12.  If such departing Subscriber leaves such employment
on or after the Prepayment Date, option 4 in Paragraph 12 is also available.

     A departing Subscriber must elect one of the available options not later
than the day prior to the last day of such departing Subscriber's employment. In
the event no election is made by a departing Subscriber's last day of
employment, the Company shall treat such failure as an election to exercise
option 3 above and shall refund the entire amount accordingly. All elections
with respect to the foregoing options upon termination of employment shall be
made on appropriate forms to be provided by the Third Party Plan Administrator.
Any prepayment shall be final and shall not thereafter benefit from any terms of
the Plan with respect to the Market Price.

     14.  CLOSING A FACILITY.  If a Subscriber for shares of Common Stock under
the Plan has his or her employment terminated by the Company during any Plan
Year, as a result of the Company closing a facility, such Subscriber shall have
the same four options as a departing Subscriber who leaves his or her employment
due to retirement, long term disability, entry into military service or death,
as set out in Paragraph 12, except that the Subscriber shall have a period of 30
days prior to his or her termination of employment to elect an option.

               Change in Control, unless the Board determines otherwise, all
               payroll deductions under the Plan will cease, and each Subscriber
               in the Plan will have the opportunity to elect in writing,

<PAGE>

               within 30 days following the Change in Control Date, one of the
               four options specified in Section 12 of the Plan. If no election
               is made by a Subscriber within such 30-day period, option 3 of
               Section 12 shall apply. For purposes of option 4, any additional
               payment required from the Subscriber shall be made by no later
               than the end of such 30-day period.

               (b)  DEFINITIONS.  "Change in Control" shall mean a change in
               control of the Company of a nature that would be required to be 
               reported in response to Item 14 of Schedule 14A of Regulation 14A
               promulgated under the Securities Exchange Act of 1934, as amended
               (the "Exchange Act"), whether or not the Company is then subject
               to such reporting requirement; provided; however, without
               limitation, that a Change in Control shall be deemed to occur if:

                    (i)    with the exception of The Dow Chemical Company, any
                    individual, partnership, firm, corporation, association,
                    trust, unincorporated organization or other entity or
                    person, or any syndicate or group deemed to be a person
                    under Section 14(d)(2) of the Exchange Act, is or becomes
                    the "beneficial owner" (as defined in Rule 13d-3 of the
                    General Rules and Regulations under the Exchange Act),
                    directly or indirectly, of securities of the Company
                    representing 20 percent or more of the combined voting power
                    of the Company's then outstanding securities entitled to
                    vote in the election of directors of the Company;

                    (ii)   during any period of two consecutive years (not
                    including any period prior to the execution of this Plan)
                    individuals who at the beginning of such period constituted
                    the Board and any new directors, whose election by the Board
                    or nomination for election by the Company's stockholders was
                    approved by a vote of at least three quarters of the
                    directors then still in office who either were directors at
                    the beginning of the period or whose election or nomination
                    for election was previously so approved, cease for any
                    reason to constitute a majority thereof;

                    (iii)  there occurs a reorganization, merger, consolidation
                    or other corporate transaction involving the Company (a
                    "Transaction"), in each case, with respect to which the
                    stockholders of the Company immediately prior to such
                    Transaction do not, immediately after the Transaction, own
                    more than 50% of the combined voting power of the Company or
                    other corporation resulting from such Transaction; or

                    (iv)   all or substantially all of the assets of the Company
                    are sold, liquidated or distributed.

     "Change in Control Date" shall mean the earliest of (i) the date on which a
Change in Control occurs, (ii) the date on which the Company executes an
agreement, the consummation of which

                                      -20-

<PAGE>

would result in the occurrence of a Change in Control, and (iii) the date the
Board approves a transaction or series of transactions, the consummation of
which would result in a Change in Control.

     16.  EMPLOYEES DEEMED "AFFILIATES" OF THE COMPANY.  Under the Rules of the
Securities and Exchange Commission, the term "affiliates" includes directors,
officers and substantial stockholders of the Company. As participation in the
Plan in any Plan Year is limited to full-time employees of the Company, the term
"affiliates" refers to those employee officers of the Company who are subject to
the reporting requirements of Section 16 of the Exchange Act.

     Subscriptions during a Plan Year by those employees who are "affiliates" of
the Company will be deemed to be irrevocable elections to participate in the
Plan during the Plan Year. Other than the circumstances described in Sections 12
and 13, or in the event of a Change in Control, such employees may not reduce or
prepay their subscriptions after the Prepayment Date but must allow for their
subscribed for shares to be paid for by payroll deduction over the entire term
of the Plan Year.

     17.  ISSUANCE OF STOCK CERTIFICATES.  After a subscription under the Plan
is fully paid (or, at the Subscriber's option, upon prepayment, or reduction and
prepayment, of his or her subscription), the Subscriber will receive a
certificate for the number of shares of Common Stock for which he or she has
paid and shall then become a stockholder and have all the rights incident
thereto, including the right to such future dividends as may be from time to
time declared by the Board. No certificate shall be issued for less than ten
shares, and not more than one certificate shall be issued pursuant to any one
subscription. An election to receive such delivery shall be irrevocable. Before
the certificate is issued, the Subscriber will not be entitled to any dividends
on Common Stock subscribed for under the Plan, and he or she will not receive
any interest on subscription payments.

     18.  ASSIGNMENT.  No eligible employee may assign his or her right to
subscribe to any other person, and no Subscriber may assign his or her
subscription to any other person. Any attempt to do so will provide cause for
the Vice President of Human Resources on behalf of the Company to treat the
action as if it were a withdrawal from the Plan for the Plan Year. After a stock
certificate has been issued, such certificate may be assigned the same as any
other stock certificate.

     19.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, ETC.  If the Company
should declare a stock dividend or distribution (as distinguished from a cash
dividend) on its issued and outstanding Common Stock, or if the Common Stock is
in any manner reclassified, the price per share and the number of shares covered
by any subscription under the Plan, but unissued at the record date of such
stock dividend, distribution or reclassification, will be changed
proportionately. No fractional shares of Common Stock shall be issued pursuant
to such an adjustment, however, and the fair market value of any fractional
shares resulting from adjustments pursuant to this paragraph shall be paid in
cash to the Subscriber.

     20.  ADDITIONAL CONDITIONS FOR NON-U.S. SUBSCRIBERS.  Additional conditions
may be incorporated in related agreements with eligible employees or Subscribers
residing in countries.

                                      -21-

<PAGE>

outside the United States, as may be required to comply with the laws and
regulations of such countries relating to the purchase or taxation of U.S.
securities.

     21.  AMENDMENT.  The Board may amend, alter or discontinue the Plan, but no
amendment or alteration shall be made during the administration of any Plan Year
which would impair the rights of any Subscriber, without his or her consent.

     22.  EMPLOYMENT RIGHTS.  The Plan shall neither impose any obligation on
the Company to continue the employment of any employee, nor impose any
obligation on any employee to remain in the employ of the Company.

     23.  WITHHOLDING OF TAXES.  The Third Party Plan Administrator, in
conjunction with the Human Resources Department, may make such provisions as it
may deem appropriate for the withholding of any taxes which it determines is
required in connection with the purchase of Common Stock under the Plan.

     24.  GOVERNING LAW.  The Plan and rights to purchase Common Stock that may
be granted hereunder shall be governed by and construed in accordance with the
laws of the State of Texas.

     This Amendment No. 1997-1 is made to the Destec Energy, Inc. Employees'

     NOW, THEREFORE, pursuant to Section 21 of the Plan, the Plan is hereby

          opportunity to elect in writing, within 30 days following the Change
          in Control Date, one of the four options specified in Section 12 of
          the Plan. If no election is made by a Subscriber within such 30-day
          period, option 3 of Section 12 shall apply. For purposes of option 4,
          any additional payment required from the Subscriber shall be made by
          no later than the end of such 30-day period.

               (ii) Notwithstanding paragraph (i) above, immediately prior to
          the occurrence of a transaction which is consummated pursuant to an
          agreement or agreements which are executed on or prior to December 31,

          cash lump sum in an amount equal to the cash amounts previously
          deducted from such Subscriber in respect of the Plan Year during which
          such Change in Control occurs. In addition, each Subscriber who is
          employed by the Company on the Change in Control Date shall be
          entitled to receive, in respect of such Plan Year, a cash lump sum
          (subject to applicable withholding) in an amount equal to the product
          of (i) the number of shares subscribed for by such Subscriber in
          respect of such Plan Year, multiplied by (ii) the excess of the price
          per share to be paid in the transaction constituting such Change in
          Control over the lower of the Plan Price or the Market Price for such
          Plan Year. Amounts payable hereunder shall be paid immediately prior
          to consummation of the Change in Control.

     The effective date of this Amendment No. 1997-1 shall be February 14, 1997.
Except as herein modified, the Plan shall remain in full force and effect.

Participant. In making such determinations, other than Deferred Stock Awards,
the Committee may take into account the nature of the services rendered by each
employee, his present and potential contributions to

<PAGE>

                                        5

the Company's success and such other factors as the Committee in its discretion
shall deem relevant.

          (c)  ADDITIONAL POWERS.  The Committee shall have such additional
powers as are delegated to it by the other provisions of the Plan. Subject to

may deem advisable to carry out the Plan, and to make all other determinations
necessary or advisable for administering the Plan. The Committee may correct any
defect or supply any omission or reconcile any inconsistency in any document or
agreement relating to an Award in the manner and to the extent it shall deem
expedient to carry it into effect. The determinations of the Committee on the
matters referred to in this Article V shall be conclusive.

          (a)  STOCK GRANT AND AWARD LIMITS.  The aggregate number of shares of
Stock that may be issued under the Plan shall not exceed 500,000 shares. Shares
of Stock shall be deemed to have been issued under the Plan only to the extent
actually issued and delivered pursuant to an Award. To the extent that an Award
lapses or the rights of a Participant terminate, any shares of Stock subject to
such Award shall again be available for issuance under the Plan. Separate stock
certificates shall be issued by the Company for those shares acquired as
Restricted Stock and for those shares acquired as Deferred Stock.

          (b)  STOCK OFFERED.  The stock to be offered pursuant to the grant of
an Award will be previously issued and outstanding Stock that has been
reacquired by Destec.


                                VII.  ELIGIBILITY

          (a)  ELIGIBLE GROUP.  All full-time employees of the Company are
eligible for participation in the Plan if they were hired before January 1,
1995. Employees hired between January 1 and September 30, 1995 will receive a
prorated award based on their job level and base salary, as of their hire date,
but will not be able to choose to receive a portion of their Award in Stock.
Each Participant's Target Award will be based upon the employee's job level and
base salary as of January 1, 1995 (or the date of hire, if later). If an
employee has serious performance problems in 1995, the employee may not receive
an Award under the Plan, as determined by his senior manager. No Awards may be
granted to any Director of Destec who is not an employee of the Company. All
Awards are subject to the limitations set forth in the Plan.

<PAGE>

                                        6

          (b)  CONDITIONS TO AWARDS.  Notwithstanding subparagraph (a) above,
all Awards are contingent upon the Company's achievement of $18,000,000 in
profits after tax for 1995.

          (c)  COMPONENTS OF AWARDS.  Each Participant's Target Award is divided
into two components:  the Individual Component and the Company Component.

          A Participant's target Individual Component is determined by
multiplying the Participant's Target Award by a percentage ranging from 33% to
50% applicable to that Participant's job level. The Individual Component of a
Participant's Award can range from 0-200% of that target. The sum of all
Individual Components set by a senior manager for his department may not exceed
100% of the total of the target Individual Components of all of the Participants
within that senior manager's department.

          A Participant's target Company Component is determined by multiplying
the Participant's Target Award by a percentage ranging from 50% to 67%
applicable to that Participant's job level. The Company Component of a
Participant's Award can range from 0-200% of that target. The multiplier
applicable to the Company Component for all Participants is determined by
reference to the performance matrix attached as Exhibit A which establishes
performance measures for the Company's 1995 after-tax profits and the Stock
price for the last two months of 1995.

          (d)  AWARD AGREEMENTS.  Destec and each Participant shall enter into
an Award Agreement setting forth the terms and conditions of each Award and such
other matters as the Committee may deem relevant. Each Award Agreement shall be
signed by an officer of Destec on behalf of Destec and by the Participant. The
Award Agreement for each Executive Participant shall also set forth the
forfeiture and transfer restrictions applicable to Deferred Stock. At the time
of granting of Awards, the Committee may, in its sole discretion, prescribe
additional terms, conditions or restrictions relating to the Awards. The Award
Agreements may also include, without limitation, provisions relating to tax
matters (including provisions (i) covering any applicable employee wage
withholding requirement and (ii) prohibiting an election by the Participant
under Section 83(b) of the Code), and any other matters not inconsistent with
the terms and provisions of the Plan that the Committee shall in its sole
discretion determine.


                         VIII.  RESTRICTED STOCK AWARDS

          (a)  FORM OF PAYMENT OF AWARDS.  Awards may be paid in cash or in a
combination of cash and Restricted Stock. Each Participant in the Plan may
irrevocably elect, in accordance with subparagraph (c) of this Article VIII, to
receive between zero and 30% of his Award in Restricted Stock, except that each
Executive Participant and member of

<PAGE>

                                        7

Destec senior management will receive a minimum of 30%, and may voluntarily
elect up to a maximum of sixty percent, of his Award in Restricted Stock. Each
Participant's designated percentage of the Award to be paid in Restricted Stock,
if any, shall be converted into a number of whole shares based on a per share
price equal to the Restricted Stock Price.

          (b)  RESTRICTION PERIOD.  For those employees who elect to receive
Restricted Stock as a part of their Award, the Restricted Stock will have a
three-year restriction period with the Restricted Stock vesting in three equal
installments on December 31 of 1996, 1997 and 1998. Except as otherwise provided
in Article X, the restriction period applicable to a particular Restricted Stock
Award shall not be changed except in the event of a Change in Control.

          (c)  ELECTION CERTIFICATES.  Each Participant in the Plan must
complete an Election Certificate stating the percentage of their Award to be
made in Restricted Stock, if any, and the portion of their Award to be paid in
cash. All Election Certificates must be received by the Human Resources
Department by June 9, 1995. All elections to receive Restricted Stock are
irrevocable.

          (d)  RECEIPT FOR RESTRICTED STOCK.  The Restricted Stock to be
received by a Participant, if any, shall be determined in accordance with each
Participant's Election Certificate and the results of individual and corporate
performance for the year.

          (e)  OTHER TERMS AND CONDITIONS.  Restricted Stock awarded as part of
a Participant's Award shall be represented by a stock certificate registered in
the name of the Participant receiving such Restricted Stock Award. Each
Participant shall have the right to receive dividends during the restriction
period, to vote the Restricted Stock and to enjoy all other stockholder rights,
except that (i) the Participant shall not be entitled to delivery of the stock
certificate until the restriction period has expired, (ii) the Participant may
not sell, transfer, pledge, exchange, hypothecate or otherwise dispose of the
Restricted Stock during the restriction period, and (iii) a breach of the terms
or a failure to satisfy the conditions established by the Committee pursuant to
a Participant's Award Agreement shall cause a forfeiture of the Restricted
Stock.


                               IX.  DEFERRED STOCK

          (a)  PROVISIONS APPLICABLE TO PARTICIPANTS WHO ARE NOT EXECUTIVE
PARTICIPANTS.  Subject to Article X, each Participant who is not an Executive
Participant shall be eligible to earn a number of shares of Deferred Stock equal
to the aggregate number of shares of Restricted Stock awarded to the Participant
as part of the Award. One-third of the number of shares of Deferred Stock for a
Participant who is not an Executive Participant will be awarded on each of
December 31, 1996, 1997, and 1998, if the average Market Price

<PAGE>

                                        8

for the 30-day period ending on such date equals or exceeds the Deferred Stock
Price applicable to that date. If the average Market Price of the Stock for the
30-day period ending on the applicable vesting date is below the Deferred Stock
Price, no Deferred Stock shall be awarded for that year. If, however, on a
subsequent vesting date the Market Price of the Stock equals or exceeds the
Deferred Stock Price applicable to that vesting date, a Participant who is not
an Executive Participant shall receive the number of shares of Deferred Stock to
be awarded as of that vesting date (i.e., one-third of the aggregate number of
shares of Deferred Stock that may be awarded hereunder) plus the aggregate
number of shares of Deferred Stock that were not awarded on prior vesting dates
because the average Market Price of the Stock on such vesting date did not equal
or exceed the Deferred Stock Price applicable to that vesting date. No shares of
Deferred Stock may be awarded or earned under the Plan after December 31, 1998.
All shares of Deferred Stock will be fully vested at the time such shares are
received by Plan Participants who are not Executive Participants and will be
awarded to the Participants at no cost, except that each Participant shall be
responsible for the payment of all amounts which are required to be withheld for
tax purposes in connection with the delivery of such shares. In no event may a
Participant receive a number of shares of Deferred Stock hereunder greater than
the number of shares of Restricted Stock awarded to the Participant and in which
the Participant ultimately vests.

          (b)  PROVISIONS APPLICABLE TO EXECUTIVE PARTICIPANTS.  On the date
that shares of Restricted Stock are awarded to an Executive Participant in
accordance with Article VIII of the Plan, the Executive Participant shall also
be awarded a number of shares of Deferred Stock equal to the aggregate number of
shares of Restricted Stock awarded as of that date. Subject to Article X below,
the shares of Deferred Stock shall vest and become nonforfeitable as follows:
(A) one-third of the shares of Deferred Stock awarded to an Executive
Participant will vest on December 31, 1996, if the average Market Price for the
30-day period ending on such date equals or exceeds the Deferred Stock Price
applicable to that date; (B) one-third of the shares of Deferred Stock (plus any
portion that was scheduled to vest but which did not vest on a prior vesting
date because the average Market Price was less than the applicable Deferred
Stock Price) will vest on December 31, 1997, if the average Market Price for the
30-day period ending on such date equals or exceeds the Deferred Stock Price
applicable to that date and (C) one-third of the shares of Deferred Stock (plus
any portion that was scheduled to vest but which did not vest on a prior vesting
date because the average Market Price was less than the applicable Deferred
Stock Price) will vest on December 31, 1998, if the average Market Price for the
30-day period ending on such date equals or exceeds the Deferred Stock Price
applicable to that date. Any shares of Deferred Stock awarded to an Executive
Participant that have not vested as of December 31, 1998 shall be immediately
forfeited. Until such time as a share of Deferred Stock is forfeited, the
Executive Participant shall have the right to receive dividends on the shares,
to vote the shares and to enjoy all other stockholder rights except that (i) the
Executive Participant shall not be entitled to delivery of the stock certificate
until the restriction period has expired, (ii) the Executive Participant may not
sell, transfer, pledge, exchange, hypothecate or otherwise

<PAGE>

                                        9

dispose of the shares of Deferred Stock until such time as the shares have
vested, and (iii) a breach of the terms or a failure to satisfy the conditions
established by the Committee pursuant to a Participant's Award Agreement shall
cause a forfeiture of the Deferred Stock.


                X.  TERMINATION OF EMPLOYMENT; CHANGE IN CONTROL

          (a)  VOLUNTARY RESIGNATION OTHER THAN FOR RETIREMENT AND INVOLUNTARY
TERMINATION.  Unless the Committee determines otherwise, upon a Participant's
resignation of employment from the Company for any reason (other than
Retirement) or the Participant's termination of employment by the Company for
any reason, the unvested portion of any shares of Restricted Stock and Deferred
Stock subject to the Award as of the date of such termination of employment
shall be immediately forfeited and, with respect to Participants who are not
Executive Participants, no additional shares of Deferred Stock may be earned
hereunder.

          (b)  DEATH AND DISABILITY.

          (i)  SHARES OF RESTRICTED STOCK.  In the event a Participant's
employment terminates as a result of the Participant's death of Disability, the
Participant (or in the event of death, the Participant's estate) will
immediately vest in a portion of the shares of Restricted Stock awarded to the
Participant in accordance with the formula [(A x B/C) - D], where "A" equals the
number of shares of Restricted Stock subject to the Award at the time of grant,
"B" equals the whole number of calendar months (not greater than 36) elapsed
from January 1, 1996 to the last day of the month in which such termination of
employment occurs, "C" equals 36, and "D" equals the number of shares of
Restricted Stock subject to the Award in respect of which the Participant has
previously vested. The result shall be rounded to the nearest whole number.

          (ii) SHARES OF DEFERRED STOCK.  In the event that employment of a
Participant terminates as a result of the Participant's death of Disability, the
Participant (or in the event of death, the Participant's estate) will
immediately vest in (in the case of Executive Participants) or be entitled to
receive (in the case of Participants who are not Executive Participants) a
number of shares of Deferred Stock subject to an Award determined in accordance
with the formula [X-Y], where "X" equals the number of shares of Restricted
Stock which have vested in accordance with the Plan, including the previous
subparagraph, and "Y" equals the number of shares of Deferred Stock subject to
the Award previously distributed to the Participant (or in the case of an
Executive Participant, in which the Executive Participant previously vested).

          (c)  RETIREMENT.  If the employment of a Participant ends as a result
of Retirement, the shares of Restricted Stock awarded to the Participant which
have not

<PAGE>

                                       10

previously vested shall immediately vest and become nonforfeitable. The portion
of the Participant's Award representing shares of Deferred Stock shall remain
outstanding and shall vest, be paid or be forfeited, as the case may be, in the
manner contemplated by Article IX.

          (d)  FORFEITURE OF REMAINING SHARES. Any shares of Restricted Stock or
Deferred Stock which do not vest or become payable in accordance with the
provisions of the Article X in connection with a Participant's termination of
employment with the Company shall be forfeited.

          (e)  CHANGE IN CONTROL.  In the event of a Change in Control, (A) all
shares of Restricted Stock previously awarded under the Plan shall become fully
vested and nonforfeitable, and (B) shares of Deferred Stock previously granted
to an Executive Participant, and shares of Deferred Stock subject to the Award
of a Participant who is not an Executive Participant shall vest, become
nonforfeitable and be immediately delivered to the Participant if either of the
following two vesting conditions have been met:  (X) the highest price paid for
a share of Stock in the Change in Control equals or exceeds the Deferred Stock
Price applicable to the vesting date in the calendar year in which the Change in
Control occurs; of (Y) the average Market Price of a share of Stock for the 30-
day period ending on the date of the Change in Control equals or exceeds the
Deferred Stock Price applicable to vesting date in the calendar year in which
the Change in Control occurs.


                         XI.  AMENDMENT AND TERMINATION

          The Board may terminate the Plan at any time with respect to any
shares of Stock for which the Awards have not theretofore been granted. The
Board shall have the right to alter or amend the Plan or any part thereof from
time to time; provided, however, that no change in any Award theretofore granted
may be made that would impair the rights of a Participant without the consent of
the Participant.


                               XII.  MISCELLANEOUS

          (a)  NO RIGHT TO AN AWARD.  Neither the adoption of the Plan by the
Company nor the execution of an Election Certificate by a Participant shall be
deemed to give an employee any right to be granted an Award hereunder. Each
Award shall be subject to the terms of the Plan and the Award Agreement duly
executed on behalf of Destec and the Participant. In the event of any conflict
between the terms of the Plan and an Election Certificate or Award Agreement,
the terms of the Plan as construed by the Committee shall govern.

<PAGE>

                                       11

          (b)  PLAN FUNDING.  The Plan shall be unfunded. The Company shall not
be required to establish any special or separate fund or to make any other
segregation of funds or assets to assure the payment of any Award.

          (c)  NO EMPLOYMENT RIGHTS CONFERRED.  Nothing contained in the Plan
shall (i) confer upon any employee any right with respect to continuation of
employment with the Company or (ii) interfere in any way with the right of the
Company to terminate his employment at any time.

          (d)  ASSIGNMENT AND WITHDRAWAL.  No Participant shall have any right
to assign his Awards under the Plan until such time as the shares of Stock
subject thereto have vested and become nonforfeitable in accordance with the
terms of the Plan and applicable Award Agreement.

          (e)  TAX WITHHOLDING.  Amounts paid under the Plan shall be subject to
all applicable federal, state, and local withholding. The Committee may
authorize the Company to lend to a Participant an amount sufficient to satisfy
all or a portion of the tax obligation incurred by a Participant as a result of
the vesting or payment of an Award. Such loan shall be on a fully recourse basis
and shall be secured by all shares of Stock subject to an Award. The interest
payable on such a loan will be the applicable federal rate for mid-term loans
with monthly compounding of interest, as determined under section 1274(d) of the
Code, on the date the loan is made to the Participant. Under the terms of the
loan, principal and interest will be due at the earliest of (i) the date the
Participant's employment is terminated with the Company; (ii) the date on which
the Participant sells shares of Stock which have vested pursuant to the terms of
an Award; or (iii) the fifth anniversary of the date of grant of the Award. If
no loan is made to a Participant, then, at the time of the vesting or payment of
an Award, the Company shall be authorized to withhold from such Participant's
other cash earnings all amounts that are required to be withheld to satisfy any
applicable withholding obligation.

          (f)  CORPORATE CHANGES.  The existence of the Plan and the Awards
granted hereunder shall not affect in any way the right or power of the Board or
the stockholders of Destec to make or authorize any adjustment,
recapitalization, reorganization or other change in Destec's capital structure
or its business, any merger or consolidation of Destec, any issue of debt or
equity securities ahead of or affecting the Stock or the rights thereof, the
dissolution or liquidation of Destec or any sale, lease, exchange or other
disposition of all or any part of its assets or business or any other corporate
act or proceeding.

          (g)  ADJUSTMENTS.  Any adjustment to outstanding Awards contemplated
by the Plan shall be subject to any required stockholder action.

<PAGE>

                                       12

          (h)  OTHER SHARES, ETC.  Except as hereinbefore expressly provided, 
the issuance by Destec of shares of stock of any class, or securities 
convertible into shares of stock of any class, for cash, property, labor or 
services, upon direct sale, upon the exercise of rights or warrants to 
subscribe therefor, or upon conversion of shares or obligations of Destec 
convertible into such shares or other securities, and in any case whether or 
not for fair value, shall not affect, and no adjustment by reason thereof 
shall be made with respect to, the number of shares of Stock subject to the 
Award theretofore granted, if any, or the Restricted Stock Price, if 
applicable.

          (i)  CONSTRUCTION.  As used in the Plan, the masculine pronoun shall
be deemed to include the feminine pronoun and a singular word shall, to the
extent applicable, include the plural. The headings of articles and paragraphs
herein are included only for convenience of reference and shall not affect the
meanings thereof.

          (j)  GOVERNING LAW.  The Plan shall be governed by, and construed in
accordance with, the laws of the State of Texas, without regard to the choice of
law provisions thereof.

                             1995 VARIABLE PAY PLAN

     This Amendment No. 1997-1 is made to the Destec Energy, Inc. 1995 Variable
Pay Plan, as amended through November 14, 1995 (the "Plan").  Capitalized terms
used but not defined herein shall have the meanings ascribed to them in the
Plan.

     WHEREAS, Destec Energy, Inc. (the "Company") is considering entering 
into a transaction or series of transactions which will result in a Change in 
Control of the Company within the meaning of the Plan;

     WHEREAS, the Company has determined that it is in the best interest and
that of its stockholders to amend the Plan as set forth herein;

     NOW, THEREFORE, pursuant to Article XI of the Plan, the Plan is hereby
amended as follows:

     1.   Section 10(e) of the Plan is amended in its entirety to read as
          follows:

               (e)  CHANGE IN CONTROL.  (i) Except as provided in paragraph (ii)
          below, in the event of a Change in Control, (A) all shares of
          Restricted Stock previously awarded under the Plan shall become fully
          vested and nonforfeitable, and (B) shares of Deferred Stock previously
          granted to an Executive Participant, and shares of Deferred Stock
          subject to the Award of a Participant who is not an Executive
          Participant shall vest, become nonforfeitable and be immediately
          delivered to the Participant if either of the following two vesting
          conditions have been met:  (X) the highest price paid for a shares of
          Stock in the Change in Control equals or exceeds the Deferred Stock
          Price applicable to the vesting date in the calendar year in which the
          Change in Control occurs, or (Y) the average Market Price of a share
          of Stock for the 30-day period ending on the date of the Change in
          Control equals or exceeds the Deferred Stock Price applicable to
          vesting date in the calendar year in which the Change in Control
          occurs.

               (ii)  Notwithstanding paragraph (i) above, immediately prior to

          consideration for their shares, (1) each Participant shall be entitled
          to receive in cancellation of all then outstanding Awards of
          Restricted Stock, and all then outstanding Awards of Deferred Stock
          (whether previously granted to an Executive Participant or subject to
          the Award of a Participant who is not an Executive Participant), in
          either case whether or not such Awards are then vested and
          nonforfeitable, and in lieu of shares of Stock otherwise deliverable
          in respect of such Awards, an amount in cash (subject to applicable
          withholding) computed by multiplying (x) the price per share to be
          paid in the transaction constituting such Change in Control by (y) the
