ITEM 1.  DESCRIPTION OF BUSINESS

BACKGROUND

         Metretek Technologies, Inc. and its subsidiaries ("Metretek" or "we")
is a diversified provider of energy measurement products, services and systems
to the energy industry. Metretek was incorporated in Delaware on April 5, 1991.
In June 1999, Metretek changed its name from "Marcum Natural Gas Services, Inc."
to Metretek Technologies, Inc. Metretek currently conducts its operations
through three subsidiaries:

         -        PowerSpring, Inc. ("PowerSpring"), based in Denver, Colorado,
                  which operates Metretek's Internet-based business to business
                  energy services hub.

         -        Metretek, Incorporated ("Metretek Florida"), based in
                  Melbourne, Florida, which designs, manufactures and sells
                  electronic devices and systems, commonly referred to as
                  automatic meter reading systems ("AMRs"), that automatically
                  monitor, record and transmit data from natural gas custody
                  transfer meters, electronic flow correctors and computers, and
                  other energy measurement products and services.

         -        Southern Flow Companies, Inc. ("Southern Flow"), based in
                  Lafayette, Louisiana, which provides a wide variety of natural
                  gas measurement services principally to producers and
                  operators of natural gas production facilities.

         Until 1997, we had also operated in the compressed natural gas ("CNG")
industry through Marcum Denver, Inc. (formerly named Marcum Fuel Systems, Inc.)
("Marcum Denver"). Marcum Denver was our wholly-owned subsidiary which engaged
in the design, manufacture and sale of CNG refueling station equipment. In June
1997, Marcum Denver discontinued its operations by selling substantially all of
its assets, because growth in the CNG industry was not meeting management's
expectations.

         During 1998, we decided to discontinue the operations of Marcum Gas
Transmission, Inc. ("MGT"). We formed MGT as a wholly-owned subsidiary to
acquire or finance the acquisition of natural gas assets through private
programs, and then to manage and maintain a small ownership interest in those
programs. Our decision to discontinue MGT's operations was based on the
declining prospects of the markets for these types of programs and in order to
enable us to focus on operations with better potential. In December 1997, MGT
sold one-third of its interests in two of the three programs it then managed,
and in March 1998, MGT liquidated the third program. We do not intend to form or
manage any new programs, although MGT will continue to manage the remaining two
programs that operate natural gas related assets until we sell MGT's interest in
those programs or liquidate the programs.

BUSINESS STRATEGY

         Our business strategy is to position ourself as an integrated provider
of data management products and services which enhance the flow of information
to the energy industry. To date, our products and services have been aimed
primarily at the natural gas industry. The natural gas industry is characterized
by relatively abundant domestic reserves, increasing demand, volatile prices and
regulatory changes such as those resulting from the deregulation of the
interstate pipeline industry. We intend to provide our products and services to
other segments of the energy industry. The energy industry generally is
undergoing fundamental regulatory and structural changes and trends. Our
strategy is to acquire, develop and operate businesses that are positioned to
take advantage of these trends.


                                       2
<PAGE>   5
         In implementing our business strategy, we have made several important
acquisitions:

         -        In 1993, we acquired substantially all of the assets of the
                  Southern Flow Companies division of Weatherford International
                  Incorporated ("Weatherford").

         -        In 1994, we acquired Metretek Florida.

         -        In 1998, we acquired the electronic corrector business from
                  American Meter Company ("American Meter").

         -        In March 2000, we acquired Mercator Energy Incorporated
                  ("Mercator").

While we regularly engage in discussions relating to potential acquisitions and
dispositions, we have no present agreements or commitments with respect to any
material acquisition or disposition.

         We have recently focused a major part of our business strategy upon the
development of our Internet-based business, PowerSpring. In furtherance of this
Internet-based business strategy, we have entered into a strategic relationship
with Scient Corporation ("Scient"), a leading eBusiness systems and strategy
advisor, and we have acquired Mercator. The goal of PowerSpring is to provide
comprehensive energy consumption data and a broad array of additional
information designed to facilitate the purchase and management of natural gas by
commercial users of natural gas. PowerSpring also intends to provide commercial
electricity users with a mechanism to manage their energy needs and reduce their
electricity costs. Our initial focus is the development of a website to provide
a single source of information and services for commercial energy users.

RECENT DEVELOPMENTS


         On February 4, 2000, we completed a $14,000,000 private placement (the
"Units Private Placement") of 7,000 units ("Units"), including 1,450 Units we
issued on December 9, 1999. Each Unit consisted of 200 shares of Common Stock, 1
share of Series B Preferred Stock and warrants ("Unit Warrants") to purchase 100
shares of Common Stock. For a description of the material terms of these
securities, see "Item 5. Market for Common Equity and Related Stockholder
Matters - Recent Sales of Unregistered Securities." In the Units Private
Placement, we issued 1,400,000 shares of Common Stock, 7,000 shares of Series B
Preferred Stock and Unit Warrants to purchase 700,000 shares of Common Stock.
The Units Private Placement was approved and ratified by our stockholders at a
special meeting of stockholders held on February 3, 2000. The Units were issued
to institutional investors and other "accredited investors" (as defined under
Regulation D under the Securities Act).

         The primary purpose of the Units Private Placement was to raise capital
to enable us to develop the Internet-based business of PowerSpring. A portion of
the proceeds was also used to repay outstanding indebtedness, and the remaining
proceeds will be used for general corporate and working capital purposes,
including potentially providing the funds to finance an acquisition opportunity,
if one were to arise.

         On March 17, 2000, we acquired Mercator through a merger with a
wholly-owned subsidiary of PowerSpring. Mercator is a Denver-based natural gas
services and brokerage company that acts as an independent broker-agent for both
producers and users. This acquisition will provide PowerSpring with Mercator's
expertise in the area of energy procurement, which is an important element in
our Internet business strategy.

         In consideration for the acquisition of Mercator, we delivered to John
A. Harpole, the President and sole shareholder of Mercator prior to the
acquisition, $408,334 in cash, a $741,666 non-negotiable promissory note payable
by PowerSpring over two years and secured by a general security interest in the
assets of PowerSpring, and 2,500,000 shares of common stock of PowerSpring.
Subsequent to the acquisition of Mercator, we own 87.5% of the outstanding
shares of PowerSpring common stock, Mr. Harpole owns 12.5% of the outstanding
shares of PowerSpring common stock, and Mercator has become a wholly-owned
subsidiary of PowerSpring. We, PowerSpring and Mr. Harpole entered into a
stockholders agreement that addresses certain rights related to Mr. Harpole's
PowerSpring common stock, including a right of first refusal held by us for any
sale of PowerSpring

                                       3
<PAGE>   6
common stock by Mr. Harpole, co-sale rights and similar rights upon PowerSpring
transactions, registration rights, and a right for Mr. Harpole to put his shares
of PowerSpring common stock back to PowerSpring at an appraised value for cash
payable over three years if PowerSpring has not completed an initial public
offering and has not sold its business within two years.

         PowerSpring also entered into a two-year employment agreement with Mr.
Harpole. Mr. Harpole will serve as the Executive Vice President, Chief Operating
Officer and a director of PowerSpring. Under the employment agreement, Mr.
Harpole received an option to purchase 60,000 shares of our Common Stock,
exercisable at $17.88 per share, and an option to purchase 200,000 shares of
PowerSpring common stock, exercisable at $.30 per share. Mr. Harpole agreed not
to compete with the business of PowerSpring for one year after the termination
of his employment.

         In September 1999, we had entered into a consulting and joint venture
agreement with Mercator, under which Mercator provided energy procurement
services to us on a consulting basis. In connection with the acquisition of
Mercator, the consulting and joint venture agreement, and a related stock option
agreement, were terminated.


POWERSPRING, INC.

         PowerSpring is our Internet-based business to business subsidiary. We
formed PowerSpring as a wholly-owned subsidiary incorporated in Delaware in
August 1999 under the name "Metretek Internet Services, Inc." In March, 2000, we
reorganized and expanded our Internet business by merging our wholly-owned
subsidiary TotalPlan, Inc. ("TotalPlan") into PowerSpring and by acquiring
Mercator. We currently conduct all our Internet-based business through
PowerSpring. As of the date of this Report, we own 87.5% of the capital stock of
PowerSpring, and PowerSpring owns all of the outstanding capital stock of
Mercator.

         Our Internet-based business objective is to be the leading Internet
provider of energy information products and services. We are developing our
Internet-based business to enable us to take our measurement information
products, services and data management technologies to a broader market of end
users of natural gas and electricity by creating a comprehensive market place on
the Internet for energy consumers and suppliers to take advantage of deregulated
energy markets. The initial focus of our Internet-based business strategy is to
develop and launch an Internet-based transactional website. After we implement
our Internet-based business strategy, we will continue to operate our Southern
Flow and Metretek Florida businesses. The technology requirements of our
Internet-based business will include automatic meter reading devices that will
be manufactured by Metretek Florida, and thus may enhance our revenues from our
Metretek Florida operations, depending on how we fix our revenue and pricing
models for our PowerSpring products and services.

         In September 1999, in furtherance of our Internet-based business
strategy, we entered into an agreement with Scient. Under the Scient agreement,
Scient is assisting and advising us in designing, developing and implementing a
viable Internet-based business strategy. Scient is a leading consultant and
advisor to businesses exploring their Internet business capabilities. We
estimate that our total costs associated with the services contemplated by the
Scient agreement will be between $6,000,000 and $8,000,000. Under the Scient
agreement, Scient is assisting us in:

         -        the conception of a viable Internet-based business strategy;

         -        the architecture of a functional and scalable transactional
                  based website;

         -        the design, engineering and development of the website;

         -        the development, selection and procurement of all applicable
                  operating software and hardware;

         -        the branding and marketing strategy for the Internet-based
                  business; and

         -        the operational structure, management and staffing of the
                  Internet-based business.


                                       4

         Background of our Internet-based business strategy. Historically, the
primary segment of Metretek Florida's business has been the sale of AMR
equipment and related software to its customers, primarily natural gas utilities
or combined natural gas/electric utilities. Typically, these customers would
purchase Metretek Florida's AMR equipment and software for installation on the
meters of their large, industrial natural gas customers.

         In 1985, the Federal Energy Regulatory Commission ("FERC") issued its
Order No. 436 that initiated deregulation of the interstate natural gas
transportation markets. This order was followed by other FERC orders, including
FERC Order No. 636, that substantially completed deregulation of the interstate
gas markets. As a result of the FERC rulings and various state level rulings and
legislation, most United States industrial and commercial natural gas customers
have, for some time, been legally able to choose a supplier of natural gas other
than their local natural gas utility. A customer that chooses to purchase
natural gas from a source other than its local utility is characterized by the
local utility as a "transportation" customer, or a customer engaged in
"deregulation purchases" of natural gas. A "transportation" customer
periodically contracts with one or more suppliers of natural gas to provide its
supply of natural gas and pays the local utility a transportation fee to
transport the natural gas from the "city gate" across the utilities distribution
system to the customer's facility. Often, the key benefit to the transportation
customer is a lower net cost of natural gas.

         A substantial percentage of industrial natural gas users in the United
States are "transportation" customers that are currently participating in the
benefits of a deregulated natural gas market, while only a very small percentage
of commercial gas users are transportation customers. We believe this largely
explains why the average natural gas prices paid by commercial customers are
higher than those paid by industrial customers, as discussed below. We also
believe that commercial natural gas customers have been precluded from
participating in the deregulated market primarily as a result of both economic
and expertise barriers to market entry. The primary goal of our eBusiness is to
remove these barriers to provide a large percentage of the commercial customer
market access to the deregulated natural gas market, as well as the commercial
electricity market.

         Deregulation of natural gas provides us with a market opportunity. A
1998 study published by the Energy Information Administration discloses that the
average natural gas burner tip cost paid by industrial users in 1997 was $3.14
per MMBTU, compared to the average cost paid by commercial natural gas customers
of $5.48 per MMBTU. Our Internet-based business strategy includes the concept of
introducing a product to the commercial natural gas market that will allow
commercial natural gas customers to substantially narrow the margin between
average commercial natural gas costs versus average industrial natural gas
costs.

         Our Internet-based business solution is to eliminate the primary
barriers to entry for commercial natural gas customers. While industrial natural
gas customers have been benefiting from deregulating natural gas markets,
commercial users of natural gas have not been. We believe commercial customers
of natural gas have been unable to benefit from deregulated markets largely as a
result of economic and expertise barriers.

         Our primary Internet-based business product is being designed to
provide a complete turn-key solution for the commercial natural gas customer and
to reduce or eliminate many of the market entry barriers. We anticipate that
this Internet-based business product will not require any up-front capital
investment by the customer, will be seamless in its application to the customer,
and will be perceived by the customer as having a small overall cost compared to
the potential savings in energy costs. We expect customers to realize a savings
in energy costs. In addition, customers will receive access to current and
historical value added consumption reports through a content and function
enriched website.

         Application of our Internet-based business strategy to the electricity
markets.The initial focus of PowerSpring will be the natural gas market, which
has been almost fully deregulated. However, the historical structure and
operating mechanics of the electricity markets are very similar to the natural
gas markets. Our AMR devices and software management programs are ideal for
application in the electricity markets. In addition, the domestic electricity
markets are about three times the size of the domestic natural gas markets.

         Deregulation of the electricity markets, while lagging behind the
deregulation of natural gas markets, but is progressing. We are aware of at
least 29 states that have either already deregulated their electricity markets,
have passed legislation to implement deregulation, or have active pilot
deregulation programs in place. We believe all of the remaining states are
currently considering some form of deregulation of electricity markets.


                                       5
<PAGE>   8
         We believe that the opportunities to create savings for customers are
potentially larger in the electricity markets than in the natural gas markets.
We also expect that many of our natural gas customers will add their electricity
needs to our PowerSpring program as their electricity markets become
deregulated.

         Timing and funding of Internet-based business project. Based on our
current schedule, we anticipate launching an operable, transaction-based
Internet-based business website in June, 2000.

         We estimate that this initial development phase of PowerSpring will
require aggregate expenditures of between $6,000,000 and $8,000,000, consisting
of consulting fees and expenses payable to Scient and costs of acquiring the
requisite technology, including hardware and software, as well as research and
development costs. Through December 31, 1999, these costs were approximately
$1.5 million. We expect that after this initial development stage is completed
and our website is launched, the further development and growth of PowerSpring,
including staffing, organizational and start-up expenses, marketing costs and
additional capital expenditures, will require significant additional funds. To
develop and expand PowerSpring, we will need to raise significant additional
funds beyond the proceeds of the Units Private Placement, from the proceeds of
public or private equity financing, debt financing or from other sources.

         We intend to raise any needed additional capital to fund the
development and operations of PowerSpring primarily through financing at the
PowerSpring level. However, depending upon the availability of capital, market
conditions, our consolidated operations and the operations of PowerSpring, we
may also or instead raise additional capital at the Metretek level. For example,
depending on market conditions and other factors we deem appropriate, we may
call our outstanding publicly trading warrants ("Dividend Warrants") for
redemption. Due to the trading price of our Common Stock, as of the date of this
Report we have the right, upon 30 days notice, to call the Dividend Warrants for
redemption at a redemption price of $.01 per Dividend Warrant, and we will
continue to have this redemption right as long as the closing sale price of the
Common Stock as reported on the Nasdaq National Market equals or exceeds $6.50
per share. We expect that, subject to market conditions, most or all Dividend
Warrants will be exercised if we call them for redemption, resulting in gross
proceeds of up to $3.5 million to us.

         Our capital raising will be subject to the consent of our lender on our
credit facility, if our credit facility is then in effect. In addition,
depending on how it is structured, our capital raising could require the consent
of the holders of our Series B Preferred Stock. We cannot assure you that
additional funds will be available to us in the future or that, if available,
additional funds can be obtained on terms favorable to us, and on terms
acceptable to our lender, if its consent is required, and on terms acceptable to
the holders of our Series B Preferred Stock, if their consent is required. In
addition, we can not assure you that any capital which is available to us will
be sufficient to facilitate this successful operation of PowerSpring. Our
inability to raise sufficient additional funds, beyond the proceeds of the Units
Private Placement, to meet the capital requirements of PowerSpring could have a
material adverse effect on our business, financial condition and results of
operations.


METRETEK, INCORPORATED

         We acquired Metretek Florida in 1994. Metretek Florida was founded in
1977 in Melbourne, Florida as a developer, manufacturer and marketer of
automated systems for monitoring and recording energy consumption. Metretek
Florida's primary focus at present is in the natural gas metering industry.

         Products. Metretek Florida's manufactured products fall into three
categories: remote data collection products; electronic corrector products; and
application-specific products. Within these categories, Metretek Florida's
products are often customized to fit the needs of its customers.

         Remote data collection products, also referred to as AMRs, attach to
existing natural gas meters and correctors. These devices are designed to
automatically collect and transmit metering data according to a schedule preset
by the customer. The AMR is an electronic printed circuit board assembly
designed and programmed to interface with an energy meter at the point of energy
consumption. The electronic board is enclosed in an assembly that attaches to
the energy meter. The energy consumption data collected by the AMR is then sent
to a Metretek Florida proprietary database consisting of a software system
running on a centrally located personal computer or

                                       6
<PAGE>   9
computer network maintained at the customer's central operations center for
further processing. Communications from the AMR to the database are generally
achieved through an existing voice grade telephone line, although cellular
telephone and radio are used when telephone lines are either not available or
are not cost-effective. Depending upon the particular features of the AMR, the
data collection may be time stamped with sufficient frequency to allow the
customer to perform critical aspects of gas flow management such as nomination,
delivery, balancing, meter indexing and billing.

         As a result of the strategic acquisition of assets from American Meter
in May 1998, Metretek Florida offers a complete line of natural gas volume
electronic corrector products. These corrector products include all or some of
the following functions:

         -        Pressure and temperature transducers to accomplish real time
                  correction of meter volumes for variations in ambient
                  temperature and pipeline pressure;

         -        Microprocessor and memory for calculation of final gas volumes
                  based upon AGA specified formulas, and for data storage;

         -        Full remote data collection capabilities;

         -        Users definable alarm detection and fault limits;

         -        User definable control features such as flow control, pipeline
                  pressure monitoring and shutdown, odorant injection;

         -        Automatic self-calibration features;

         -        Compatibility with numerous volumetric meters; and

         -        Capability of providing corrector features for multiple meters
                  simultaneously.

         In addition to the two primary product lines referred to above,
Metretek Florida also manufactures "application-specific" products designed for
certain market niches. These include cathodic protection monitors, used to
monitor rectifier and cathodic protection system failure, and gas pipeline
pressure monitors.

         Services. In addition to its manufactured product lines, Metretek
Florida also provides certain services to its customers. Metretek Florida offers
post-sale support services which help create and maintain customer satisfaction
and loyalty. Metretek Florida has recently commenced offering "energy data
collection and management services" under the trade name "TotalPlan(TM)" for
customers who are unable or unwilling to make the investment required to own a
Metretek Florida system. In this turn-key service, Metretek Florida provides and
installs the required remote data collection hardware, collects and formats the
remote data in Melbourne, Florida, and then sends the data electronically to the
customer for a per month or per communication fee. Management believes this
service will help Metretek Florida penetrate the commercial account AMR markets.

         In 1997, Metretek Florida commenced offering contract manufacturing of
electronic circuit boards by acquiring Sigma VI, Inc. ("Sigma VI"). Metretek
Florida expanded this business in June 1998 by acquiring the business and assets
of Quality Contract Manufacturing, Inc. ("QCMI"). Sigma VI and QCMI were two
small contract manufacturers of electronic circuit board and cable assemblies
located in Melbourne, Florida. Metretek Florida made these acquisitions to gain
control of the quality and timeliness of Metretek Florida's manufactured circuit
boards and subassemblies and to diversify and expand the business of Metretek
Florida. With the automated equipment and experienced personnel acquired,
Metretek Florida is able to offer contract manufacturing to local electronics
manufacturers who have high quality, short run, quick turnaround requirements.

         A critical element of Metretek Florida's product line is its data
collection and management capability. With the exception of the Sigma VI
products, virtually all of Metretek Florida's products are integrated with
Metretek Florida's database software package, the DC 2000 system. This system
provides substantial flexibility for

                                       7
<PAGE>   10
the generation of reports in formats useful for Metretek's customers to perform
data management functions. As a result of the acquisition of the American Meter
electronic corrector product line, Metretek Florida and American Meter are
working towards the cross-functionality of certain of their products in an
effort to enhance data management by Metretek Florida's customers.

         Markets. Historically, Metretek Florida's AMR products have been
marketed principally to natural gas local distribution companies ("LDCs").
Typically, LDCs install these devices in conjunction with custody transfer
meters on their larger customers for the purpose of meeting deregulation
requirements. Sixty of the largest one hundred LDCs in North America currently
utilize Metretek Florida systems to monitor and record the natural gas
consumption of their industrial and commercial accounts. The timely and accurate
information provided by the Metretek Florida system is used by the operations,
engineering, natural gas supply, marketing, customer service and billing
departments of the LDC. In the future, Metretek Florida intends to focus its
marketing efforts directly toward the commercial and industrial users of natural
gas and electricity. Markets for the electronic corrector products are much
broader and include not only LDCs and their commercial and industrial customers,
but also natural gas transportation and distribution companies, natural gas
gatherers and processors, natural gas producers and operators, and natural gas
brokers.

         The U.S. market for remote data collection products for natural gas
meters consists of three classes of natural gas users:

         -        Industrial users, consisting of the largest 250,000 domestic
                  users of natural gas, such as steel mills, glass manufacturing
                  plants, and natural gas fired power generator plants;

         -        Commercial users, consisting of approximately 4,000,000
                  natural gas customers, such as multi-family apartment
                  complexes, restaurants, factories and other customers with
                  multiple locations within a relatively confined area; and

         -        Residential users, which are the smallest users and include
                  primarily residential single family houses.

         Historically, Metretek Florida has been the leading provider of AMRs to
the industrial natural gas market, which is becoming saturated. The primary
target for Metretek Florida's AMR products is the recently developing commercial
natural gas user market, Metretek Florida does not consider the residential
natural gas user sector of the market to be a viable target market for its
products, primarily due to the low margins inherent in that market.

         Marketing and Customer Service. Metretek Florida distributes its
products by a direct sales force in the United States, and uses contract
representatives and distributors to distribute its products outside the United
States. Metretek Florida also provides implementation services for its customers
designed to meet its customer's specific needs. Metretek Florida offers a
maintenance and support team in Melbourne, Florida that offers 24-hour,
toll-free hotline support, customer service representatives, consulting
services, equipment repair and preventative maintenance, software support and
maintenance, system troubleshooting and network management services. Metretek
Florida's marketing strategy includes utilizing its close contacts with the
utility industry through its sales representatives. Metretek Florida also
participates in trade shows, symposiums and conferences designed to expand
industry awareness of its products. Metretek Florida also utilizes direct
mailing of brochures and newsletters, and has a home page on the Internet.

         International. Outside of North America, Metretek Florida has sold AMR
systems to natural gas distribution utility companies in the United Kingdom, the
Netherlands, Pakistan, Australia, Argentina and Brazil. Over the past three
years, approximately 11% to 21% of Metretek Florida's annual sales have been to
customers outside the U.S. All of the eight major gas distribution utility
companies in Canada own and operate Metretek Florida systems. Metretek Europe
Limited, a wholly-owned subsidiary of Metretek Florida located in Camberley,
England, sells Metretek Florida products primarily in Western Europe.

         Acquisitions. Metretek Florida's business strategy includes the
acquisition of, and strategic alliances with, measurement equipment providers
and software application developers that can utilize or enhance Metretek
Florida's offering of products and services.


                                       8
<PAGE>   11
         On May 4, 1998, Metretek Florida acquired substantially all of the
assets and business of American Meter pertaining to electronic correctors and
non-radio-frequency meter reading devices in the natural gas and electric
utility industry. American Meter is ultimately controlled by Ruhrgas AG, a
German corporation. The assets acquired by Metretek Florida include certain
inventory, equipment, trademarks and technology of American Meter used in the
design, manufacture and sales of electronic measurement process control and
telemetry systems to utility companies in the natural gas and petroleum
industries. In connection with the acquisition, Metretek Florida assumed certain
transitional employee costs and product warranty obligations of American Meter.
The assets and business operations acquired have been relocated to Metretek
Florida's existing facility in Melbourne, Florida.

         In consideration for the purchase of the assets and business, we paid
and delivered to American Meter at the closing an aggregate purchase price
consisting of $1,300,000 in cash, 439,560 unregistered shares of Common Stock,
and a $1,200,000 convertible subordinated promissory note, $600,000 of the
principal of which was contingent upon Metretek Florida exceeding certain sales
targets, during an adjustment period, which targets were not met. Subsequent to
the closing, the purchase price was adjusted down by $85,000 to reflect a
decrease in American Meter's inventory between December 31, 1997 and May 4,
1998, partially offset by transitional costs assumed by Metretek Florida. After
the adjustment period, the final principal amount of the convertible note was
fixed at $600,000.

         American Meter has given notice that it desires to convert the note,
under its terms, into 105,495 shares of Common Stock at the rate of $5.6875 of
principal per share, plus 26,373 Dividend Warrants. The American Meter note bore
interest on the unpaid principal balance at a fixed rate equal to 7.5% per
annum, payable quarterly in arrears, and was due and payable May 4, 2002.
American Meter has the one-time demand right to cause the shares of Common Stock
issued to American Meter at the closing or issuable upon conversion of the
American Meter note to be registered under the Securities Act and applicable
state securities laws, and also has certain piggy-back registration rights to
include such shares in any registration statement filed by us, subject to
customary underwriter cutbacks.

         Metretek Florida also entered into a license agreement with American
Meter, providing for the license by American Meter to Metretek Florida of
certain operating software, and the development, manufacture and sale by
Metretek Florida to American Meter of certain electronic components and related
equipment pertaining to electronic temperature and pressure correction to be
imbedded within certain new rotary and turbine meters of American Meter. The
American Meter license agreement also grants to American Meter and its
affiliates the right to sell Metretek Florida products in the United States and
Canada at certain agreed-upon prices. American Meter has also entered into a
non-competition agreement with Metretek Florida, under which American Meter
agreed not to compete with Metretek Florida in the acquired business for five
years from the closing date. In 1998, in connection with this acquisition, Harry
I. Skilton, President of American Meter, became a member of our Board of
Directors.

SOUTHERN FLOW COMPANIES, INC.

         Southern Flow provides a variety of natural gas measurement services
principally to customers involved in natural gas production, gathering,
transportation and processing. We commenced our operations in this line of
business in 1991 by acquiring an existing business. This business was expanded
significantly in 1993 when we acquired substantially all of the assets of the
Southern Flow Companies division of Weatherford. Through its predecessors,
Southern Flow has provided measurement services to the natural gas industry
since 1953.

         Southern Flow provides a broad array of integrated natural gas
measurement services, including on-site field services, chart processing and
analysis, laboratory analysis, and data management and reporting. Southern
Flow's field services including the installation, testing, calibration, sales
and maintenance of measurement equipment and instruments. Southern Flow's chart
processing operations include analyzing, digitizing and auditing well charts and
providing custom reports as requested by the customer. Southern Flow also
provides laboratory analysis of natural gas and natural gas liquids chemical and
energy content. As part of its services to its customers, Southern Flow
maintains a proprietary database software system which calculates and summarizes
energy measurement data for its customers and allows for easy transfer and
integration of such data into customer's accounting systems. As an integral part
of these services, Southern Flow maintains a comprehensive inventory of natural
gas meters and metering parts, and derives approximately 25% of its annual
revenues from its "parts resale"

                                       9
<PAGE>   12
business. Southern Flow provides its services through 9 division offices located
throughout the Gulf of Mexico, Southwest, Mid-Continent and Rocky Mountain
regions.

         Natural gas measurement services are used by producers of natural gas
and pipeline companies to verify volumes of natural gas custody transfers. To
ensure that such data is accurate, on-site field services and data collection
must be coordinated with chart integration and data development and management
to produce timely and accurate reports.

         The market for independent natural gas measurement services is
fragmented, with no single company having the ability to exercise control. Many
natural gas producers and operators, and most natural gas pipeline and
transportation companies, internally perform some or all of their natural gas
measurement services. In addition to price, the primary consideration for
natural gas measurement customers is the quality of services and the ability to
maintain data integrity, because natural gas measurement has a direct effect on
the natural gas producer's revenue and royalty and working interest owner
obligations. We believe that we are able to effectively compete by:

         -        providing dependable integrated measurement services;

         -        maintaining local offices in proximity to our customer base;
                  and

         -        retaining experienced and competent personnel.

COMPETITION

         The markets for energy products, services, technology and information
are highly competitive and subject to rapidly changing technology, new and
emerging products, services and technologies, frequent product and service
performance improvements and evolving industry standards. In addition, we
anticipate facing intense competition in our new online business, especially as
the use of the Internet for energy products and services grows. The growth
potential and deregulatory environment of the energy market have attracted and
are anticipated to continue to attract many new start-ups as well as established
businesses from different industries. Competition may also increase as a result
of industry consolidation. Increased competition could result in price
reductions, reduced gross margins, loss of market share, inability to penetrate
new markets or to develop new markets, any of which could have a material and
adverse effect on our business.

         Our current and prospective competitors fall into the following
categories:

         -        large and well established distributors of energy measurement,
                  monitoring and information products and services, such as
                  Cellnet Data Systems, Inc., Itron Corp. and Whisper
                  Communications;

         -        large, well established and diversified companies like
                  Schlumberger, General Electric and Asea Brown Boveri that have
                  divisions or subsidiaries devoted to our markets;

         -        in-house services provided by utilities and major oil and gas
                  companies;

         -        large, well established and diversified oil and gas companies
                  like Enron Corp. and Duke Energy Corp.; and

         -        numerous prospective competitors that may offer energy
                  information.

         We believe that our ability to compete successfully will depend upon
many factors, many of which are outside of our control. These factors include:

         -        our responsiveness to customers needs;

         -        functionality of our and our competitors' products and
                  services;


                                       10
<PAGE>   13
         -        speed of implementation of new products and services and
                  enhancement to existing products and services;

         -        price of competitors' products and services;

         -        ease of use of products and services;

         -        performance and features of products and services;

         -        quality and reliability;

         -        reputation;

         -        quality of customer service and support;

         -        sales and marketing efforts;

         -        our ability to sustain our strategic relationships; and

         -        the timing and market acceptance of new products and services
                  and enhancements to existing products and services developed
                  by us and our competitors.

         We believe that we compete favorably with respect to the above factors,
although with respect to products and services that we do not believe price is a
principal competitive factor, we do not compete on the basis of price. In order
to be successful in the future, we must continue to respond promptly and
effectively to the challenges of technological change and its competitors'
innovations. We cannot guarantee that our products and services will continue to
compete favorably or that we will be successful in facing the increasing
competition for new products and enhancements introduced by its existing
competitors or new competition entering the market.

         Many of our existing competitors, as well as a number of potential new
competitors, have longer operating histories, greater name recognition, larger
customer bases and significantly greater financial, technical, marketing,
manufacturing and other resources than we do. This may enable our competitors to
respond more quickly to new or emerging technologies and changes in customer
requirements or preferences and to devote greater resources to the development,
promotion and sale of their products and services than we can. Our competitors
may be able to undertake more extensive marketing campaigns, adopt more
aggressive pricing policies and make more attractive offers to potential
employees, customers, strategic partners and suppliers and vendors than we can.
Our competitors may develop products and services that are equal or superior to
the products and services offered by us or that achieve greater market
acceptance than our products do. In addition, current and potential competitors
have established or may establish cooperative relationships among themselves or
with third parties to improve their ability to address the needs of our existing
and prospective customers. As a result, it is possible that new competitors may
emerge and rapidly acquire significant market share or impede our ability to
acquire market share in new markets. Increased competition is likely to result
in price reductions, reduced gross margins and loss of market share, and the
inability to develop new businesses, which could materially and adversely affect
our business. We cannot assure that we will have the financial resources,
technical expertise, portfolio of market or services or marketing and support
capabilities to successfully compete.

         The market for Metretek Florida's products and services is very
competitive. Although Metretek Florida's product offering is very specific to
the requirements for industrial and commercial meter reading/monitoring in
natural gas distribution utility companies, many suppliers of residential meter
reading systems also offer products for commercial and/or industrial
applications and can be formidable competitors for utility companies desiring to
implement residential meter reading and to have all automatic/remote meter
reading, including industrial and commercial, performed on a single system.
Also, major natural gas meter and instrument manufacturers offer systems to
remotely read and interrogate their own equipment, and utility companies that
use certain manufacturers' meters exclusively may also choose to buy their
communication and data collection products as well. We believe that several
large suppliers of equipment, services or technology to the utility industry
have developed or are currently developing products or services for the market
in which Metretek Florida is currently or is intending to compete. Most of
Metretek Florida's present and potential competitors have substantially greater
financial, marketing, technical and manufacturing resources, as well as greater
name recognition and experience, than Metretek Florida. Metretek Florida
competes with a large number of existing and potential competitors in these


                                       11
<PAGE>   14
markets, some of which do not compete in all of the same markets as Metretek
Florida. In addition, current and potential competitors may make strategic
acquisitions or establish cooperative relationships among themselves or with
third parties that increase their ability to address the needs of Metretek
Florida's prospective customers. Metretek Florida competes primarily on the
basis of product quality and reliability, applications expertise, and the
quality of its service and support.

         Numerous companies compete directly with Southern Flow in the natural
gas measurement services industry, including companies which provide the same
services as Southern Flow and those which provide additional or related field
services. Although a majority of natural gas measurement services is currently
performed internally by natural gas producers and pipeline companies, most of
Southern Flow's direct competition consists of small measurement companies
providing limited services and serving limited geographical areas. Southern Flow
offers a complete range of natural gas measurement services over a wide
geographical area which management believes offers Southern Flow advantages over
its competitors.

         PowerSpring will be competing in the Internet energy products, services
and information markets. These markets are evolving rapidly, are highly
competitive and are likely to be characterized by an increasing number of market
entrants and by industry consolidation. Because there are no substantial
barriers to entry, we expect that PowerSpring will face competition from both
existing competitors and new market entrants in the future. We believe that
participants in this market must grow rapidly and achieve a significant presence
to compete effectively. We believe that the primary competitive factors facing
PowerSpring are:

         -        a state-of-the-art infrastructure providing availability,
                  speed, scalability and security;

         -        site and Internet application hosting and management
                  expertise;

         -        fast and reliable Internet connectivity;

         -        a reputation for high-quality service and superior customer
                  service and support;

         -        numerous and diverse service offerings and timely addition of
                  value-added services;

         -        brand recognition;

         -        competitive pricing; and

         -        adequate capital to permit continued investment in
                  infrastructure, customer service and support and sales and
                  marketing.

         We expect our Internet competitors to come from three different areas:
energy service providers, online exchanges and measurement companies. We expect
our competitors will range from purely online energy offerings such as
Enermetrix to large off-line competitors such as Enron. Energy service providers
will be significant competitors of ours because they target the same commercial
and industrial market that we will target. Examples of competitive energy
service providers include Enron, Duke Energy, PG&E Energy Services, New
Energy/Power Direct, Energy.com and Utility.com. Companies that provide the
wholesale online exchanges, such Altra and Houston Street.com, enable customers
to trade energy in an on-line environment. Companies offering retail on-line
exchanges include Enermetrix.com.

REGULATION

         Regulation of Natural Gas. Our operations are affected in various
degrees by political developments and federal and state laws and regulations. In
particular, natural gas production, operations and economics are affected by
price controls, by environmental, tax and other laws relating to the natural gas
industry, by changes in such laws and by changing administrative regulations and
the interpretations and application of such laws, rules and regulations. Natural
gas industry legislation and agency regulation is periodically changed for a
variety of political, economic and other reasons. Natural gas sales have been
deregulated at the wholesale, or pipeline, level since

                                       12
<PAGE>   15
Federal Energy Regulatory Commission Order 636 was issued in 1992. Since that
time, individual states have been studying various methods for deregulating
natural gas sales at the retail level. Many state utility commissions are
currently conducting pilot programs that allow residential and small commercial
consumers to select a provider of their choice, other than the local
distribution company, to supply their natural gas. As natural gas sales are
deregulated, on a state by state basis, we believe that timely collection and
reporting of consumption data will be needed and desired by utility companies
and energy service providers, particularly for residential and commercial
customers who are purchasing natural gas on an aggregate basis. We believe that
PowerSpring and Metretek Florida will benefit from such a regulatory
environment.

         Regulation of Electricity. The electric utility industry is undergoing
fundamental structure changes due to deregulation. The traditional utility
structure, consisting of a vertically integrated system operating as a natural
monopoly with rates set in relation to cost, has historically presented
utilities with little incentive to improve service quality or operating
efficiency. Customer demands and regulatory mandates by federal and state
governments are opening the electric utility market to competition, forcing
electric utilities to transform themselves from regulated monopolies into
competitive enterprises. While regulatory initiatives vary from state to state,
many involve a shift from rate-of-return rate making, in which an electric
utility's rates are determined by its return on assets, to performance-based
rate making, in which an electric utility's rates and profitability are based
upon its cost, efficiency, and service quality. This deregulatory movement in
the electricity industry follows a similar deregulatory movement in the natural
gas utility industry. Today, commercial and industrial natural gas customers can
purchase natural gas directly from producers or brokers, while utilities are
required to provide transportation of such natural gas to customers' facilities.
We expect a similar result from electricity deregulation.

         Several major electric utilities have recently entered into merger
agreements and other consolidation transactions and bought and sold generation
assets. The restructuring has also focused on opening the electric power
production industry, in certain markets, to full competition in the next few
years and ultimately providing customers access to multiple suppliers. Federal
legislation, such as the National Energy Policy Act of 1992 (the "Energy Policy
Act"), has opened utility transmission lines to independent power producers in
an effort to increase competition in the wholesale electric power generation
market. Under the Energy Policy Act, individual states have the sole authority
to mandate the transport and delivery or "wheeling" of electric power to retail
customers. As a result, at least 18 states now have legislation or final
commission orders to mandate retail wheeling and nearly all of the other states
are in various stages of considering the implementation of retail wheeling and
unbundling, both at legislative and regulatory levels. Meanwhile, a number of
other states are also requiring utilities to "unbundle," or offer as separate
services, metering, billing and collection, and more states are formally
investigating such unbundling. Unbundling implies that a third party, such as a
new power market participant, would be free to own the electric meter that
measures usage and attaches to a commercial, industrial or residential
customer's premises. Traditionally, the owner of the meter has been the electric
utility which has also had a monopoly in providing metering, billing, and
collection services. In California, the state which has to date advanced the
furthest in the deregulation process, the California Public Utility Commission
mandated competitive retail wheeling and unbundling effective April 1, 1998 for
large commercial and industrial customers and January 1, 1999 for all remaining
customers. By mandating retail wheeling the California PUC allows the customer
to choose among energy service providers. The California PUC has also mandated
hourly metering capability for commercial and industrial customers choosing
direct access and which require more than 50 kW of power, which will be
decreased to 20kW in the year 2002.

         The changing regulatory environment means that new power market
participants will be entering into a market traditionally dominated by
established utilities. To date, more than 33 parties have registered with the
California PUC as Registered Energy Service Providers to provide electric
services in California. The established utilities are focused on retaining and
increasing their market share as a result of competition. Both new power market
participants and established utilities will be striving to optimize their
offerings and to distinguish themselves in the market. The same capabilities
will enable energy service providers to meet regulatory metering and forecasting
requirements, offer superior, competitively-priced services, collect customer
information and diversify by adding additional applications as available.

         We believe that competition will require recordation of electric power
consumption data more frequently than is presently customary through a much
wider use of daily, hourly and possibly even more frequent meter readings. In
fact, hourly meter reading has already been mandated for commercial and
industrial customers in

                                       13
<PAGE>   16
California. Other deregulating states which require hourly metering for
commercial and industrial customers include Michigan and Arizona. It is possible
that other states will follow. We believe that our AMR technology, or meter
reading technology similar to it, will be needed to do such hourly meter
reading.

         We believe that regulatory reform will result in new opportunities for
us to provide our products and services, such as AMR and other functions
typically performed by utilities, directly to end-user customers. In addition,
we believe there are a number of new business opportunities that will be able to
develop for capitalizing on the value of the information that can be derived
from our products and services.

         Regulation of Internet Activities. At present, there are few laws or
regulations directed specifically at Internet commerce. However, because of the
Internet's popularity and increasing use, laws and regulations directly
applicable to e-commerce or Internet communications are becoming more prevalent.
These laws and regulations may cover issues such as the collection and use of
data from web site visitors and related privacy issues, pricing, content,
copyrights, distribution and the quality of goods and services. The enactment of
any additional laws or regulations may impede the growth of the Internet and
Internet commerce which could decrease the revenue potential or increase the
costs of PowerSpring. Specific areas of legislative activity regulating Internet
commerce including the following:

         -        Taxes. Congress enacted a three-year moratorium, ending on
                  October 27, 2001, on the application of "discriminatory" or
                  "special" taxes by the states on Internet access or on
                  products and services delivered over the Internet. Congress
                  further declared that there will be no federal taxes on
                  e-commerce until the end of the moratorium. However, this
                  moratorium does not prevent states from taxing activities or
                  goods and services that the states would otherwise have the
                  power to tax. Furthermore, the moratorium does not apply to
                  certain state taxes that were in place before the moratorium
                  was enacted.

         -        Online Privacy. Both Congress and the Federal Trade Commission
                  are considering regulating the extent to which companies
                  should be able to use and disclose information they obtain
                  online from consumers. If any regulations are enacted, we may
                  find certain of our contemplated marketing activities
                  restricted. Also, the European Union has directed its member
                  nations to enact much more stringent privacy protection laws
                  than are generally found in the United States, and has
                  threatened to prohibit the export of certain personal data to
                  United States companies if similar measures are not adopted.
                  Such a prohibition could limit our growth in foreign markets.
                  The Department of Commerce is negotiating with the Federal
                  Trade Commission to provide exemptions from the European Union
                  regulations, but the outcome of these negotiations is
                  uncertain.

         -        Regulation of Commerce Facilities. To some extent, the rapid
                  growth of the Internet in the United States has been due to
                  the relative lack of government intervention in the
                  marketplace for Internet access. Lack of intervention may not
                  continue in the future. For example, several
                  telecommunications carriers are seeking to have
                  telecommunications over the Internet regulated by the Federal
                  Communications Commission in the same manner as other
                  telecommunications services. Additionally, local telephone
                  carriers have petitioned the Federal Communications Commission
                  to regulate Internet service providers in a manner similar to
                  long distance telephone carriers and to impose access fees on
                  these providers. Some Internet service providers are seeking
                  to have broadband Internet access over cable systems regulated
                  in much the same manner as telephone services, which could
                  slow the development of broadband Internet access services.
                  Because of these proceedings or others, new laws or
                  regulations could be enacted which could burden the companies
                  that provide the infrastructure on which the Internet is
                  based, thereby slowing the rapid expansion of the medium and
                  its availability to new users.

         Moreover, the applicability to the Internet of existing laws governing
such issues as intellectual property ownership and infringement, copyright,
patent, trademark, trade secret, obscenity, libel, employment and personal
privacy is uncertain and developing.

         Regulation of International Operations. Our international operations
are also subject to the political, economic and other uncertainties of doing
business abroad including, among others, risks of war, cancellation,


                                       14
<PAGE>   17
expropriation, renegotiation or modification of contracts, export and
transportation regulations and tariffs, taxation and royalty policies, foreign
exchange restrictions, international monetary fluctuations and other hazards
arising out of foreign government sovereignty over certain areas in which we
conduct, plan to conduct or in the future may conduct operations.

         Regulation of Environment. While various federal, state and local laws
and regulations covering the discharge of materials into the environment, or
otherwise relating to the protection of the environment, may affect our
operations as a result of their effect on natural gas development, exploration,
production, transportation and dispensing operations, our operations are not
currently subject to substantial environmental laws and regulations. We believe
we are in material compliance with those environmental laws and regulations to
which we are subject. It is not anticipated that we will be required in the near
future to expend amounts that are material in relation to our total capital
expenditures program by reason of environmental laws and regulations. However,
inasmuch as such laws and regulations are frequently changed, we are unable to
predict the ultimate effect on us and on the cost of compliance.

EMPLOYEES

         At February 29, 2000, we had 228 full-time employees. None of our
employees are covered by a collective bargaining agreement. We believe that our
relations with our employees are good.

RESEARCH AND DEVELOPMENT

         Our basic research and development activities have been historically
conducted by Metretek Florida. Metretek Florida conducts research and
development directed towards improvements in its product and service offering
which address anticipated customer needs and potential new markets. Current
research and development activities for existing customers and markets are aimed
at expanding Metretek Florida's wireless communication capability, cost
reduction of pulse collection devices, and a new software operating system.
Products and services currently under development for new markets include an
electric meter interface and a monitoring and recording system for liquid levels
in storage tanks (primarily for use in propane distribution systems).

         Recently, we commenced an extensive research and development program
for the business of PowerSpring. We incurred $961,383 and $2,225,758 for
research and development expenses during the years ended December 31, 1998 and
1999 respectively. We intend to continue to allocate resources to the research
and development of new Metretek Florida products and services in the future, but
our highest research and development priority currently is PowerSpring's
Internet-based business. Our future services will depend, in part, on our
services in these development projects which will require continual substantial
investments.

RAW MATERIALS

         Our subsidiaries purchase memory chips, electronic components, printed
circuit boards, fabricated sheet metal parts, machined components, aluminum,
metallic castings and various other raw materials for their products. While, in
the opinion of management, the loss of any one supplier of materials would not
have a material adverse impact on our business or operations, shortages in
certain components such as memory chips, supply problems from our suppliers or
our inability to develop alternative sources of supply quickly or
cost-effectively could materially impact our ability to manufacture our products
and therefore could adversely affect our business and operations. We attempt to
mitigate this risk by maintaining an inventory of such materials.

PROPRIETARY RIGHTS

         Our success and ability to compete are dependent in part upon our
proprietary rights and technology. We rely on a combination of patents,
copyrights, trademarks and trade secret laws to establish and protect our rights
in its products and proprietary technology. Although we maintain certain patents
related to our business, we do not believe that our competitive position is
dependent upon patent protection or that our operations are dependent upon any
individual patent. Nevertheless, we believe that the following factors are more
essential to protecting our technology leadership position:


                                       15
<PAGE>   18
         -        the technological and creative skills of our personnel;

         -        new products and service development;

         -        frequent product and service enhancements;

         -        name recognition;

         -        customer training and support; and

         -        reliable product support.

         We generally require our employees and consultants to enter into
nondisclosure and assignment of invention agreements to limit use of, access to
and distribution of proprietary technology. There can be no assurance that our
means of protecting our proprietary rights in the United States or abroad will
be adequate. In addition, the laws of some foreign countries may not protect our
proprietary rights as fully or in the same manner as do the laws in the United
States. Despite our efforts to protect our proprietary rights, it may be
possible for unauthorized third parties to copy, reverse engineer or otherwise
obtain, use or exploit aspects of our products, develop similar technology
independently or otherwise obtain and use information that we regard as
proprietary. Our actual and potential competitors may independently develop
technologies similar or superior to our technology or design around the
proprietary rights owned by us. Although we are not aware that our products
infringe on the proprietary rights of third parties, we cannot assure you that
others will not assert claims of infringement against us in the future or that,
if made, such claims will not be successful.


ADDITIONAL FACTORS THAT MAY AFFECT OUR BUSINESS AND FUTURE RESULTS

         Our business and future operating results may be affected by many
factors, risks and uncertainties, including those set forth below and those
contained else where in this report. In addition, the risks described below are
not the only risks facing us. There may be additional risks and uncertainties
that we do not currently consider material or that are not presently known to
us. If any of the following risks were to occur, our business, prospects,
assets, financial condition, results of operations and cash flows could be
materially and adversely affected. When we say that something could or will have
a material adverse effect on us or our business, we mean that it could or will
have one or more of these effects.

         WE HAVE A HISTORY OF LOSSES, AND WE MAY NEVER BECOME PROFITABLE

         We have incurred net losses on an annual basis during each year since
our incorporation. We incurred net losses of approximately $0.3 million and $3.7
million for the years ended December 31, 1998 and 1999. At December 31, 1999, we
had an accumulated deficit of approximately $25.2 million. Due to the design,
creation and implementation of PowerSpring, our Internet-based business, which
will require us to make significant expenditures, we expect operating losses to
continue for the foreseeable future. We also anticipate increased expenses as we
support, expand and improve PowerSpring and its infrastructure, invest in new
Internet applications, enhance our management expertise, expand our sales
efforts and pursue strategic Internet relationships. In addition, our
Internet-based business strategy is unproven. We may never generate sufficient
revenues to achieve profitability. Even if we do achieve profitability, we may
not be able to sustain or increase that profitability on a quarterly or annual
basis in the future.

         FLUCTUATIONS IN OUR QUARTERLY OPERATING RESULTS MAY ADVERSELY AFFECT
         THE TRADING PRICE OF OUR COMMON STOCK

         Our quarterly revenues, expenses, margins and results of operations
have fluctuated significantly in the past and are expected to continue to
fluctuate significantly in the future due to a variety of factors, many of which
are outside of our control and any of which may cause the trading price of our
Common Stock to fluctuate. These factors include:


                                       16
<PAGE>   19
         -        the size, timing and terms of sales and orders;

         -        the amount and timing of expenditures on PowerSpring;

         -        our ability to implement our business plan and strategy with
                  respect to PowerSpring and the timing of its implementation;

         -        the timing, pricing and market acceptance of our new products
                  and services, especially those related to PowerSpring, and
                  those of our competitors;

         -        the pace of development of PowerSpring;

         -        the success of our brand building and marketing campaigns for
                  our PowerSpring products and services;

         -        the growth of the market for online energy products, services
                  and information;

         -        our ability to effectively manage our growth during the
                  anticipated rapid expansion of PowerSpring;

         -        changes in our pricing policies and those of our competitors;

         -        variations in the length of our product and service
                  implementation process;

         -        the mix of products and services sold;

         -        the mix of international and domestic revenues;

         -        the life cycles of our products and services;

         -        budgeting cycles of utilities;

         -        general economic and political conditions;

         -        economic conditions in the energy industry in general and the
                  natural gas and electricity industries in particular;

         -        the effects of governmental regulations and regulatory changes
                  in our current and new markets;

         -        prices charged by our suppliers;

         -        our ability to make successful acquisitions of technology or
                  businesses, and the costs related to such acquisitions;

         -        changes in our operating expenses; and

         -        the maintenance and development of business relationships with
                  strategic partners.

         Because many of our operating expenses, other than those related to
PowerSpring, are relatively fixed, a shortfall in anticipated revenue or delay
in recognizing revenue could cause our operating results to vary significantly
from quarter-to-quarter and could result in significant operating losses in any
particular quarter. The timing of large individual sales is also difficult for
us to predict. In addition, expenditures on PowerSpring will be significant and
will vary in the forseeable future. If our revenues fall below our expectations
in any particular quarter, our business could be materially adversely affected.
If our revenues fall below our expectations, we will not be able to reduce our
expenses rapidly in response to the short-fall and could suffer significant
operating losses.

         Due to all of these factors and the other risks discussed in this Item,
you should not rely on quarter-to-quarter comparisons of our results of
operations as an indication of our future performance. It is possible that in
some future periods our results of operations may be below the expectations of
public market analysts and investors. As a result, the trading price of our
Common Stock may fall.

         BECAUSE POWERSPRING, OUR INTERNET-BASED BUSINESS, HAS VIRTUALLY NO
         OPERATING HISTORY AND OUR INTERNET-BASED BUSINESS STRATEGY IS STILL
         BEING DEVELOPED AND IS UNPROVEN, LIMITED INFORMATION IS AVAILABLE UPON
         WHICH YOU CAN EVALUATE POWERSPRING


                                       17
<PAGE>   20
         Our business strategy and future success is highly dependent upon our
ability to develop PowerSpring. Our Internet-based business strategy is based on
an unproven business model, and our operating, sales and other strategies are
still being developed. Our Internet-based business strategy depends on the
willingness of commercial users of natural gas and electricity to purchase, at a
price profitable to us, a package consisting of energy data management equipment
and energy purchasing resources. It also depends on our ability to develop a
business that will generate significant revenues, profits and cash flow through
the offering of energy products, services and information over the Internet.
PowerSpring will not be launched until June 2000. Accordingly, we have virtually
no operating history to provide you upon which you can evaluate PowerSpring.

         As a company developing a new business in the new and rapidly evolving
markets for Internet products and services generally, and Internet energy
products, services and information specifically, we face numerous risks and
uncertainties which are described in this Item as well as other parts of this
Report. Some of these risks relate to our ability to:

         -        anticipate and adapt to the changing regulatory climate for
                  energy products and services;

         -        anticipate and adapt to the changing Internet market;

         -        attract customers to our new Internet-based business;

         -        collect energy research and other energy information adequate
                  to support a market for Internet services;

         -        implement our sales and marketing initiatives, both
                  domestically and internationally;

         -        attract, retain and motivate qualified personnel;

         -        respond to actions taken by our competitors;

         -        integrate acquired businesses, technologies, products and
                  services;

         -        generate revenues and sales of new products and services;

         -        implement an effective marketing strategy to promote awareness
                  of our new businesses; and

         -        develop and deploy successful versions of the software
                  necessary for our services.

         Our business and financial results in the future will depend heavily on
market acceptance and profitability of PowerSpring. If we are unsuccessful in
addressing these risks or in executing our business strategies, our business
would be materially and adversely affected.

         IF THE INTERNET IS NOT WIDELY ACCEPTED BY COMMERCIAL USERS OF ENERGY AS
         A MEDIUM FOR COMMERCE, OUR BUSINESS WOULD BE MATERIALLY AND ADVERSELY
         AFFECTED

         In the future, we expect to derive a significant amount of our
revenues, income and cash flow from PowerSpring, which is our Internet business
to business services hub subsidiary. We cannot assure you that Internet-based
commerce for energy products and services, especially by commercial users of
energy, will ever grow to account for substantial revenues, income and cash
flow, or when this growth might occur. Our business would suffer if the market
for Internet-based commerce for energy products and services fails to develop or
develops more slowly than expected. Our business would also suffer if we are
unable to adapt to new forms of, or new pricing models for, Internet-based
commerce for energy products and services.

         The viability and future growth of the Internet as a means of commerce
depends on several factors, including:

         -        the Internet's ability to handle increased activity;

         -        the Internet's ability to operate as a fast, reliable and
                  secure network;

         -        potential changes in governmental regulation of the Internet;

         -        the ability of the Internet infrastructure to support the
                  growing demands placed on it;


                                       18
<PAGE>   21
         -        Internet access costs;

         -        the performance and reliability of products and services
                  offered on the Internet as the number of users and amount of
                  traffic increases;

         -        the ability of businesses to adequately address security and
                  privacy concerns; and

         -        the nature and pace of technological changes relating to the
                  Internet.

         Moreover, critical issues concerning the commercial use of the
Internet, including data corruption, cost, ease of use, accessibility and
quality of service, remain unresolved and may negatively affect commerce on the
Internet. These issues will need to be addressed in order for the market for
on-line energy products and services to grow. It is difficult to predict when
Internet-based commerce for energy products and services will emerge and obtain
market acceptance and be profitable. This makes it difficult to project our
future revenues, results of operations and cash flows. We cannot assure you that
we will be successful in selling energy products and services over the Internet
or in capturing a significant share of the market for Internet-based energy
products and services.

         CONCERNS ABOUT SECURITY OF ELECTRONIC COMMERCE TRANSACTIONS AND
         CONFIDENTIALITY OF INFORMATION ON THE INTERNET MAY IMPEDE THE GROWTH OF
         POWERSPRING

         A significant barrier to electronic commerce has been the need for
security. Internet usage could decline if any well-publicized compromise of
security occurs. We may incur significant costs to protect against the threat of
security breaches or to alleviate problems caused by these breaches.
Unauthorized persons could attempt to penetrate our network security. If
successful, they could misappropriate proprietary information or cause
interruptions in our services. As a result, we may be required to expend capital
and resources to protect against or to alleviate these problems. Security
breaches could have a material and adverse effect on our business.

         OUR NEW INTERNET-BASED BUSINESS STRATEGY WILL BE DEPENDENT UPON THE
         DEVELOPMENT AND MAINTENANCE OF THE INTERNET INFRASTRUCTURE

         The success of our new Internet-based business strategy will depend
largely on the development and maintenance of the Internet infrastructure. This
includes maintenance of a reliable network backbone with the necessary speed,
data capacity and security, as well as timely development of complimentary
products such as high-speed modems, for providing reliable Internet access and
services. Because on-line commerce is new and evolving, we cannot predict
whether the Internet will prove to be a viable commercial marketplace in the
long term. The Internet has experienced, and is likely to continue to
experience, significant growth in the number of users and the amount of traffic.
If the Internet continues to experience increased numbers of users increased
frequency of use, or more complex requirement, the Internet infrastructure may
be unable to support the demands placed on it. In addition, the performance of
the Internet may be harmed by increased users or more complex requirements.

         The Internet has experienced a variety of outages and other delays as a
result of damages to portions of its infrastructure, and it could face outages
and delays in the future. These outages and delays could reduce the level of
Internet usage as well as the level of traffic in the processing of commerce on
our website. In addition, the Internet could lose its viability due to delays in
the development or adoption of new standards and protocols to handle increased
levels of activity or due to increased governmental regulation. The
infrastructure and complimentary products or services necessary to make the
Internet a viable commercial marketplace for the long-term may not be developed
successfully or in a timely manner. Even if these products or services are
developed, the Internet may not become a viable commercial marketplace for
services such as those that we intend to offer.

         WE MAY BE UNABLE TO SUCCESSFULLY MANAGE THE EXPECTED EXPANSION OF
         POWERSPRING

         Our anticipated future growth as a result of PowerSpring may place a
significant strain on our management, operating systems and resources. We cannot
successfully implement our Internet-based business strategy if we fail to manage
our growth. We expect that we will need to attract and retain competent
personnel and to continue to improve our financial managerial controls and
reporting systems and procedures. We will also need to continue to expand and
maintain close coordination among our technical, accounting, finance and sales
and marketing

                                       19
<PAGE>   22
organizations. In addition, our systems, procedures or controls may be
inadequate to support our operations, in which case management may be unable to
exploit opportunities for our products and services. Failure to manage our
growth effectively and successfully integrate any acquisition or strategic
relationships could materially and adversely affect our business.

         BECAUSE OUR FUTURE GROWTH, IN OUR TRADITIONAL BUSINESSES AND IN
         POWERSPRING, IS DEPENDENT IN LARGE PART UPON THE DEREGULATION OF THE
         ELECTRICITY INDUSTRY, DELAYS IN THE DEREGULATION OF THE ELECTRICITY
         MARKETS, OR IN THE ELECTRICITY INDUSTRY'S COMPETITIVE RESPONSE TO
         DEREGULATION, MAY MATERIALLY AND ADVERSELY AFFECT OUR BUSINESS

         The electricity industry is currently undergoing fundamental structural
changes due to deregulation, similar to what the natural gas utility industry
has undergone. A key component of our business strategies, in both our
traditional businesses, especially Metretek Florida, and our new Internet-based
business, PowerSpring, is to take advantage of opportunities created by the
deregulation of the electricity industry as the result of the need for more and
more frequent electricity consumption information. A principal expected benefit
to us of electricity deregulation is the ability of commercial and industrial
electricity customers to purchase electricity directly from multiple suppliers,
rather than solely from the local utility. This will require these electricity
customers to obtain timely electricity consumption data. If the deregulatory
environment does not continue or slows down, or if the market is slow to respond
to the opportunities made available by the changes in the deregulation of the
electricity industry, then commercial electricity customers may not purchase our
products, may purchase less of our products or may not purchase our products
until later than we anticipate. Failure of electricity industry deregulation to
result in a significant increase in the purchases of our products and services
would materially and adversely affect our business.

         BECAUSE WE ARE DEPENDENT UPON THE UTILITY INDUSTRY FOR A SIGNIFICANT
         PORTION OF OUR REVENUE, CONTINUED REDUCTIONS OF PURCHASES OF OUR
         PRODUCTS AND SERVICES BY UTILITIES CAUSED BY REGULATORY REFORM MAY
         MATERIALLY AND ADVERSELY AFFECT OUR BUSINESS

         We currently derive a significant portion of our revenue from sales of
our products and services to the utility industry, and particularly the natural
gas utility industry. We have experienced variability of operating results on
both an annual and quarterly basis due primarily to utility purchasing patterns,
and delays of purchasing decisions by utilities, as the result of mergers and
acquisitions in the utility industry or potential changes to the federal and
state regulatory framework within which the utility industry operates. The
utility industry is generally characterized by long budgeting, purchasing and
regulatory process cycles that can take up to several years to complete. Our
utility customers typically issue requests for quotes and proposals, establish
committees to evaluate the purchase proposals, review different technical
options with vendors, analyze performance and cost/benefit justifications and
perform a regulatory review, in addition to applying a normal budget approval
process within the utility. In addition, utilities may defer purchases of our
products and services if the utilities reduce capital expenditures as the result
of mergers and acquisitions, pending or unfavorable regulatory decisions, poor
revenues due to weather conditions, rising interest rates or general economic
downturns, among other factors. The natural gas utility industry has been
virtually the sole customer for our automatic meter reading systems. However,
over the last few years, the uncertainty in the utility industry that has
resulted from the regulatory uncertainty in the current era of deregulation, has
caused utilities to defer even further purchases of our products and services.
The continuation of this uncertain regulatory climate will materially and
adversely affect our revenues from sales of meter reading devices.

         The domestic utility industry is currently the focus of regulatory
reform initiatives in virtually every state. These initiatives have resulted in
significant uncertainty for industry participants and raise concerns regarding
assets that would not be considered for recovery through rate payer charges.
This regulatory climate has caused most utilities to delay purchasing decisions
that involve significant capital commitments. As a result of these purchasing
decision delays, utilities have reduced their purchases of our products and
services. While we expect some states will act on these regulatory reform
initiatives in the near future, we cannot assure you that the current regulatory
uncertainty will be resolved in the short term. In addition, new regulatory
initiatives could have a material and adverse effect on our business. Moreover,
in part as a result of the competitive pressures in the utility industry arising
from the regulatory reform process, many utilities are pursuing merger and
acquisition strategies. We have experienced considerable delays in purchase
decisions by utilities that have become parties to merger or acquisition
transactions. Typically, capital expenditure purchase decisions are put on hold
indefinitely when merger

                                       20
<PAGE>   23
negotiations begin. If this pattern of merger and acquisition activity among
utilities continues, our business may be materially and adversely affected.

         In addition, if any of the utilities that account for a significant
portion of our revenues decide to significantly reduce their purchases of our
products and services, our business may be materially and adversely affected.

         WE WILL REQUIRE A SUBSTANTIAL AMOUNT OF ADDITIONAL CAPITAL TO FINANCE
         OUR BUSINESS, ESPECIALLY POWERSPRING, BUT WE MAY NOT BE ABLE TO OBTAIN
         A SUFFICIENT AMOUNT OF FUNDS TO DO SO

         We will require substantial additional funds to design, create,
develop, implement, market and operate PowerSpring, our new Internet-based
business. If we cannot raise sufficient funds on a timely basis, we will not be
able to complete the development, implementation and successful operations of
PowerSpring, and our business will be materially and adversely affected.

         We estimate that the initial development phase to launch PowerSpring
will require estimated expenditures of between $6,000,000 and $8,000,000,
consisting of consulting fees and expenses payable to Scient and costs of
acquiring the requisite technology, including hardware and software, as well as
research and development costs. We expect that after this initial development
stage is completed and its web site is launched, the further development and
growth of PowerSpring, including staffing, organizational and start-up expenses,
marketing costs and additional capital expenditures, will require significant
additional funds. In order to so develop and expand PowerSpring, we will need to
raise the significant additional funds, beyond the proceeds of the Units Private
Placement, from the proceeds of public or private equity financing, debt
financing or from other sources. We intend to raise any needed additional
capital to fund the development and operations of PowerSpring primarily through
financing at the PowerSpring level. However, depending upon the availability of
capital, market conditions, our consolidation operations and the operations of
PowerSpring, we may also or instead raise additional capital at the Metretek
Technologies level. For example, depending on market conditions and other
factors we deem appropriate, we may call the outstanding Dividend Warrants for
redemption.

         Virtually any such capital raising will be subject to the consent of
our lender on our credit facility, if the credit facility is then in effect. In
addition, depending on how it is structured, this capital raising could require
the consent of the holders of our Series B Preferred Stock. We cannot assure you
that any additional funds will be available to us in the future or that, if
available, funds can be obtained on terms favorable to us, and on terms
acceptable to our lender, if its consent is required, and on terms acceptable to
the holders of the Series B Preferred Stock, if their consent is required. In
addition, we cannot assure you that available capital will be sufficient for the
successful operation of PowerSpring. Our inability to raise sufficient
additional funds, beyond the proceeds of the Units Private Placement, to meet
the capital requirements of PowerSpring could have a material adverse effect on
our business, financial condition and results of operations.

         In addition to our need to raise capital to fund PowerSpring, we will
need to raise additional capital in the future to either repay or refinance any
indebtedness we incur in the future to finance our operations, the growth of our
current business or acquisition opportunities. The Series B Preferred Stock
bears a cumulative dividend at the rate of 8% per year and, if not earlier
converted into Common Stock, is subject to mandatory redemption on December 9,
2004 at a redemption price equal to the liquidation preference, currently
$7,000,000. In addition, unanticipated events, over which we may have no
control, could also increase our operating costs or decrease our ability to
generate revenues from product and service sales. We will also require
additional capital in the future to make any significant acquisitions of
businesses or technologies. We have a $5 million revolving line of credit with
our current lender which expires in March 2001. Our ability to borrow funds
under this credit facility is limited to our loan availability based upon our
assets, primarily our accounts receivable and inventory, and is limited to $3
million by the terms of the Series B Preferred Stock. As of December 31, 1999,
we had a total loan availability of approximately $3.6 million, and of that we
had borrowed approximately $0.3 million. The amount of our loan availability, as
well as the amount we borrow, will change in the future depending on our asset
base and our capital requirements. Any amount outstanding under our credit
facility in March 2001 will need to either be repaid by us, refinanced by a new
lender or investor, or extended by our current lender. We cannot estimate the
amount that we will have borrowed under the credit facility when it expires, and
we cannot assure you that we will be able to repay, refinance or extend that
indebtedness at that time.


                                       21
<PAGE>   24
         To finance PowerSpring and the growth of our other businesses, and to
repay or refinance any indebtedness we might incur, we will need to raise a
substantial amount of additional capital from the public or private sales of
equity securities, debt financing, sales of assets, calling the Dividend
Warrants for redemption, or from other sources. Additional financing may not be
available to us when we need it or, if available, it may not be on terms
satisfactory to us, or we may not be able to obtain the required consents to
complete the financing. Obtaining additional financing will depend on many
factors, including market conditions, our operating performance and investor
sentiment. Terms of debt financing could restrict our ability to operate our
business, or to expand our operations. In addition, if we raise capital by
issuing capital stock or securities convertible into capital stock, our
stockholders could suffer a significant dilution of their percentage ownership
interests, and the new capital stock or other new securities could have rights,
preferences or privileges senior to those of our current stockholders. If we are
unable to raise sufficient additional financing on terms satisfactory to us,
then our business will be materially and adversely affected.

         RESTRICTIONS IMPOSED ON US AS A RESULT OF THE TERMS OF OUR CURRENT
         INDEBTEDNESS AND OUR SERIES B PREFERRED STOCK COULD LIMIT HOW WE
         CONDUCT OUR BUSINESS AND OUR ABILITY TO RAISE ADDITIONAL CAPITAL

         The terms of our current credit facility and of our Series B Preferred
Stock contain financial and operating covenants that limit the discretion of our
management. These covenants place significant restrictions on our ability to:

         -        incur additional indebtedness;

         -        create liens or other encumbrances;

         -        issue or redeem securities;

         -        make dividend payments and investments;

         -        amend our charter documents;

         -        sell or otherwise dispose of our assets;

         -        liquidate or dissolve;

         -        merge or consolidate with other companies; or

         -        reorganize, recapitalize or engage in a similar business
                  transaction.

         Any future financing arrangements will likely contain similar or more
restrictive covenants. As a result of these restrictions, we may be:

         -        limited in how we conduct our business;

         -        unable to raise additional debt or equity financing to operate
                  during general economic or business downturns; and

         -        unable to compete effectively or to take advantage of new
                  business opportunities.

         DIVIDENDS ON THE SERIES B PREFERRED STOCK WILL INCREASE OUR FUTURE NET
         LOSS AVAILABLE TO COMMON SHAREHOLDERS AND OUR NET LOSS PER COMMON SHARE

         After issuing the Series B Preferred Stock, we will recognize the 8%
coupon rate and certain "deemed distributions" as dividends on the Series B
Preferred Stock. The proceeds from the sale of the Units were allocated to the
Common Stock, the Unit Warrants and the Series B Preferred Stock based on the
relative fair value of each. This allocation process resulted in the Series B
Preferred Stock that we sold on February 4, 2000 being initially recorded at a
discount from its $1,000 per share liquidation value. This discount will be
recorded as a distribution over the term of the Series B Preferred Stock.
Another discount resulted from the increase in the fair market value of a share
of our Common Stock from the date we offered to sell 5,550 Units to February 4,
2000, the date we actually issued the Units. This increase caused the conversion
feature of the Series B Preferred Stock to be "in the money" on February 4,
2000. The discount related to the "in the money" conversion feature will be
recorded as a distribution

                                       22
<PAGE>   25
between the February 4, 2000 and June 9, 2000, after which date the Series B
Preferred Stock can first be converted into our Common Stock. The Series B
Preferred Stock dividends will increase our future net loss available to common
shareholders and net loss per common share, which could adversely affect the
trading price of our Common Stock.

         RAPID TECHNOLOGICAL CHANGES MAY PREVENT US FROM REMAINING CURRENT WITH
         OUR TECHNOLOGICAL RESOURCES AND MAINTAINING COMPETITIVE PRODUCT AND
         SERVICE OFFERINGS

         The markets in which our businesses currently operate and PowerSpring
will operate are characterized by rapid technological change, frequent new and
enhanced product and service introductions, evolving industry standards and
changes in customer needs. Significant technological changes could render our
existing products, services and technology, including our planned PowerSpring
products and services, obsolete. The Internet market's growth and intense
competition exacerbate these conditions. Our future success will depend, in
part, on our ability to:

         -        effectively use and develop leading technologies;

         -        continue to develop our technical expertise;

         -        enhance our current products and services;

         -        develop new products and services that meet changing customer
                  needs; and

         -        respond to emerging industry standards and technological
                  changes in a cost-effective manner.

         If we are unable to successfully respond to these developments or do
not respond to them in a cost-effective manner, then our business will be
materially and adversely affected. We cannot assure you that we will be
successful in responding to changing technology or market needs. In addition,
products, services and technologies developed by others may render our products,
services and technologies uncompetitive or obsolete.

         Even if we do successfully respond to technological advances and
emerging industry standards, the integration of new technology may require
substantial time and expense, and we cannot assure you that we will succeed in
adapting our products, services and technology in a timely and cost-effective
manner. We may experience financial or technical difficulties that could prevent
us from introducing new or enhanced products or services. Furthermore, these new
or enhanced products and services may contain problems that are discovered after
they are introduced. We may need to significantly modify the design of these
products and services to correct problems. Rapidly changing Internet technology
and operating systems may impede market acceptance of our PowerSpring products
and services. Our business could be materially and adversely affected if we
experience difficulties in introducing new or enhanced services and products or
if these products and services are not received favorably by our customers.

         Development and enhancement of our products and services will require
significant additional expenses and could strain our management, financial and
operational resources. The lack of market acceptance of our products or services
or our inability to generate sufficient revenues from this development or
enhancements to offset their costs could have a material adverse effect on our
business. We have experienced delays in releasing new products and product
enhancements and may experience similar delays in the future. These delays or
problems in the installation of implementation of our new products and services
and enhancements may cause customers to forego purchases of our products and
services to purchase those of our competitors.

         CHANGES IN OUR PRODUCT MIX COULD MATERIALLY AND ADVERSELY AFFECT OUR
         BUSINESS

         The margins on our revenues from some of our product and service
offerings is higher than the margins on our other product and service offerings.
For example, revenues from some of Metretek Florida's AMR devices have
significantly higher margins than Metretek Florida's contract manufacturing
revenues. In addition, we do not know what the prices and costs, and therefore
we cannot estimate the margins, of our future PowerSpring products and services
will be. These new products and services may have lower margins than our current
products and

                                       23
<PAGE>   26
services. If in the future we derive a proportionately greater percentage of our
revenues from lower margin products and services, then our overall margins on
our total revenues will decrease and, accordingly, will result in lower net
income, or higher net losses, and less cash flow on the same amount of revenues.

         OUR MANAGEMENT OF PRIVATE ENERGY PROGRAMS PRESENTS RISKS TO US

         MGT is our subsidiary that manages and holds a small ownership interest
in two private energy programs that own natural gas assets. The operations of
MGT have been discontinued and MGT does not intend to form any new private
programs. MGT is pursuing the sale of the existing energy programs but will
continue managing the two business trusts that operate these energy programs
only until those programs are sold or liquidated or until MGT's interests and
management obligations in those programs are sold. These private programs were
financed by private placements of equity interest raising capital to acquire the
assets and business operated by the programs. Our management of these energy
programs presents risks to us, including:

         -        material and adverse changes in the business, results of
                  operations and financial conditions of the programs due to
                  events, conditions and factors outside the control of MGT,
                  such as general and local conditions affecting the energy
                  market generally and the revenues of the programs
                  specifically;

         -        lawsuits by investors in these programs who become
                  dissatisfied with the result of these programs;

         -        changes in the regulatory environment relating to these
                  programs;

         -        reliance upon significant suppliers and customers by these
                  programs;

         -        hazards of energy facilities; and

         -        changes in technology.

         If any of these risks materialize and we are unsuccessful in addressing
these risks, our business could be materially and adversely affected.

         OUR INTERNATIONAL OPERATIONS ARE SUBJECT TO MANY RISKS AND
         UNCERTAINTIES

         We market and sell some of our products and services in international
markets. Our revenues from sales into international markets were approximately
8% and 5% of our consolidated revenues in fiscal years 1998 and 1999. One
component of our strategy for future growth involves the expansion of our
products and services into new international markets and the expansion of our
marketing efforts in our current international markets. This expansion will
require significant management attention and financial resources to establish
additional offices, hire additional personnel, localize and market products and
services in foreign markets and to develop relationships with international
service providers. However, we have only limited experience in developing
localized versions of our products and services and in developing relationships
with international service providers. We cannot assure you that we will be
successful in expanding our international operations, or that revenues from
international operations will be sufficient to offset these additional costs. If
revenues from international operations are not adequate to offset the additional
expense from expanding these international operations, our business could be
materially and adversely affected.

         In addition to the uncertainty regarding our ability to generate
sufficient revenues from foreign operations and to expand our international
presence, there are risks inherent in doing business on an international level,
including:

         -        adverse changes in applicable laws and regulatory
                  requirements;

         -        import and export restrictions;

         -        export controls relating to technology;

         -        tariffs and other trade barriers;

         -        less favorable intellectual property laws;

         -        difficulties in staffing and managing foreign operations;


                                       24
<PAGE>   27
         -        political instability;

         -        fluctuations in currency exchange rates;

         -        potential adverse tax consequences;

         -        cultural and language difficulties;

         -        the impact of adverse economic and market conditions in
                  foreign countries;

         -        the potential exchange and repatriation of foreign earnings;

         -        localization and translation of products and services;

         -        difficulties in collecting accounts receivable and longer
                  collection periods; and

         -        the impact of local economic conditions and practices.

         Our success in expanding our international operations will depend in
large part of our ability to anticipate and effectively manage these and other
risks. We have limited experience in conducting our business outside the United
States and may encounter unforeseen difficulties in conducting operations in
foreign countries. In addition, while our current products are designed to meet
relevant regulatory requirements of foreign markets in which they are sold, any
inability to obtain any required foreign regulatory approval and any changes in
foreign regulatory requirements could have a material adverse effect on our
ability to conduct business in these markets. In addition, we may confront
significant challenges in developing and implementing localized versions of our
systems due to many factors including the different standards among utilities on
a country by country basis. We cannot assure you that we will be able to
successfully market, sell and deliver our products and services in these foreign
markets.

         OUR MARKETS ARE HIGHLY COMPETITIVE, AND THE COMPETITION WE FACE COULD
         MATERIALLY AND ADVERSELY AFFECT OUR ABILITY TO SELL OUR CURRENT
         PRODUCTS AND SERVICES, EXPAND OUR CURRENT BUSINESSES AND DEVELOP OUR
         NEW BUSINESSES

         The markets for energy products, services, technology and information
are highly competitive and subject to rapidly changing technology, new and
converging products, services and technologies, frequent product and service
performance improvements and evolving industry standards. In addition, we
anticipate facing intense competition in our Internet business, especially as
the use of the Internet for energy products and services grows. The growth
potential and deregulatory environment of the energy market have attracted and
are anticipated to continue to attract many new start-ups as well as established
businesses from different industries. Competition may also increase as a result
of industry consolidation. Increased competition could result in price
reductions, reduced gross margins, loss of market share, inability to penetrate
new markets or to develop new markets, any of which could have a material and
adverse effect on our business.

         Many of our existing competitors, as well as a number of potential new
competitors, have longer operating histories, greater name recognition, larger
customer bases and significantly greater financial, technical, marketing,
manufacturing and other resources than we do. This may enable our competitors to
respond more quickly to new or emerging technologies and changes in customer
requirements or preferences and to devote greater resources to the development,
promotion and sale of their products and services than we can. Our competitors
may be able to undertake more extensive marketing campaigns, adopt more
aggressive pricing policies and make more attractive offers to potential
employees, customers, strategic partners and suppliers and vendors than we can.
Our competitors may develop products and services that are equal or superior to
the products and services offered by us or that achieve greater market
acceptance than our products do. In addition, current and potential competitors
have established or may establish cooperative relationships among themselves or
with third parties to improve their ability to address the needs of our existing
and prospective customers. As a result, it is possible that new competitors may
emerge and rapidly acquire significant market share or impede our ability to
acquire market share in new markets. Increased competition is likely to result
in price reductions, reduced gross margins and loss of market share, and the
inability to develop new businesses, which could materially and adversely affect
our business. We cannot assure you that we will have the financial resources,
technical expertise, portfolio of market or services or marketing and support
capabilities to successfully compete.

         WE MAY BE UNABLE TO SUCCESSFULLY ACQUIRE OTHER COMPANIES, FORM
         STRATEGIC ALLIANCES OR SUCCESSFULLY INTEGRATE ANY ACQUISITION OR
         ALLIANCE

         In the past, we have grown by acquiring complimentary businesses,
technologies, services and products and entering into strategic alliances with
complimentary businesses. We evaluate potential acquisition opportunities from
time to time, including those that could be material in size and scope. As part
of our growth strategy, we intend to continue to evaluate potential
acquisitions, investment opportunities and strategic alliances on an on-going
basis as they present themselves to facilitate our ability to enhance our
existing products and services and introduce new products and services on a
timely basis. However, we do not know if we will be able to identify any future
opportunities that we believe will be beneficial for us. Even if we are able to
identify an appropriate acquisition opportunity, we may not be able to
successfully finance the acquisition. A failure to identify or finance future
acquisitions may impair our growth and adversely affect our business.

         Any future acquisition involves risks commonly encountered in business
relationships, including:

         -        difficulties in assimilating and integrating the operations,
                  technologies, products and services of the acquired
                  businesses;

         -        difficulties in retaining key personnel;

         -        diversion of management's time and resources away from our
                  normal daily operations;

         -        difficulties in successfully incorporating licensed or
                  acquired technology and rights into our product and service
                  offerings;

         -        difficulties in maintaining uniform standards, controls,
                  procedures and policies within the two organizations;

         -        changes in management resulting from an alliance or
                  acquisition could impair relationships with employees and
                  customers of the acquired company's risks of entering markets
                  in which we have no or limited direct prior experience;

         -        potential disruptions of our ongoing business;

         -        unexpected costs associated with the acquisition; and

         -        potential additional expenses associated with amortization of
                  acquired intangible assets, integration costs and
                  unanticipated liabilities or contingencies.

         We cannot assure you that any acquisition of new businesses or
technology will lead to the successful development of new or enhanced products
and services, or that any new or enhanced products and services, if developed,
will achieve market acceptance or prove to be profitable.

         For these reasons, future acquisitions could materially and adversely
affect our existing businesses. Moreover, we cannot predict the accounting
treatment of any acquisition, in part because we cannot be certain whether
current accounting regulations, conventions or interpretations will prevail in
the future.

         In addition, to finance any future acquisitions, it may be necessary
for us to incur additional indebtedness or raise additional funds to public or
private financings. This financing may not be available to us or may be
available on terms satisfactory to us or to those whose consents are required
for our financing. Available equity or debt financing available may materially
and adversely affect our business and operations and, in the case of equity
financings, may significantly dilute the percentage ownership interests of our
stockholders.

         We currently have no agreements, commitments or obligations with
respect to any material acquisition. We cannot assure you that we will make any
additional acquisitions or that any acquisitions, if made, will be successful,
will assist us in the accomplishment of our business strategy, or will generate
sufficient revenues to offset the associated costs and other adverse effects or
will otherwise result in us receiving the intended benefits of the acquisition.

         IF WE FAIL TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY RIGHTS OR IF
         WE FACE A CLAIM OF INTELLECTUAL PROPERTY INFRINGEMENT BY A THIRD PARTY,
         WE COULD LOSE IMPORTANT INTELLECTUAL PROPERTY RIGHTS OR BE LIABLE FOR
         SIGNIFICANT DAMAGES AND OUR BUSINESS COULD BE MATERIALLY AND ADVERSELY
         AFFECTED

         Our success and ability to compete depends, in substantial part, upon
our intellectual property rights and technology. We rely primarily on patent,
copyright, trademark and trade secret laws, along with confidentiality
procedures, contractual provisions and licensing arrangements, to establish and
protect our proprietary rights. Although we hold patents and trademarks in our
business, we believe that the success of our business depends more upon our
proprietary technology, information, processes and know-how than on patents or
trademarks. Much of our proprietary information and technology is not patented
and may not be patentable. Moreover, we have applied for registration of a
number of key trademarks and service marks and intend to introduce new
trademarks and service marks. We may not be successful in obtaining registration
for one or more of these marks.

         Despite our efforts to protect our intellectual property rights, our
actions may be inadequate to protect these rights or to prevent others from
claiming violations of their proprietary rights. It may be possible for
unauthorized third parties to copy, reverse engineer or otherwise obtain, use or
exploit aspects of our products and services, develop similar technology
independently, or otherwise obtain and use information that we regard as
proprietary. We cannot assure you that our competitors will not independently
develop technology similar or superior to our technology or design around our
proprietary rights. We generally require our employees, consultants and
strategic partners to enter into confidentiality and proprietary invention
agreements with us to limit use of, access to, and distribution of our
proprietary technology. Our intellectual property rights with respect to
PowerSpring may not be viable or of value in the future because of validity,
enforceability and scope or protection of proprietary rights in Internet-related
industries is uncertain and still evolving. In addition, the laws of some
foreign countries may not protect our proprietary rights as fully or in the same
manner as the laws of the United States.

         We may need to resort to litigation to enforce our intellectual
property rights, to protect our trade secrets, and to determine the validity and
scope of other companies' proprietary rights, or to defend against claims of
infringement or validity in the future. However, litigation could result in
significant costs or the diversion of management and financial resources. We
cannot assure you that any litigation will be successful or will prevail over
counterclaims against us. As a result, any litigation could materially and
adversely affect our business.

         Although we are not aware that any of our products, services or
technologies infringe on the proprietary rights of third parties, we cannot be
certain that our products, services and technologies do not or will not infringe
valid intellectual property rights held by third parties. In addition, we cannot
assure you that third parties will not claim that we have infringed their
intellectual property rights. We may be subject to legal proceedings and claims
from time to time relating to the intellectual property of third parties in the
ordinary course of our business. We may incur substantial expenses in defending
against these third party infringement claims, regardless of their merit.
Successful infringement claims against us could result in substantial monetary
liability or may materially disrupt the conduct of our business. In addition,
even if we prevail on these claims, this litigation could be time-consuming and
expensive to defend, and could result in the diversion of our time and
attention, which could materially and adversely affect our business.

         POTENTIAL PROBLEMS RESULTING FROM THE YEAR 2000 ISSUE COULD CAUSE US TO
         INCUR UNANTICIPATED EXPENSE, DIVERT MANAGEMENT'S TIME AND ATTENTION AND
         DECREASE USE OF INTERNET SERVICES, ALL OF WHICH COULD MATERIALLY AND
         ADVERSELY AFFECT OUR BUSINESS

         The "Year 2000 issue," which was anticipated to present potential risks
and uncertainties to virtually all businesses, is the result of computer
programs and systems that use two digits, rather than four digits, to define the
applicable year. As a result of the Year 2000 issue, these programs and systems
could have failed or malfunctioned because they could not distinguish between
twentieth century and twenty-first century dates. This, in turn, could have
resulted in a major system failure or miscalculations, including an inability to
process transactions, send invoices or engage in normal business activities. In
addition, Year 2000 problems could subject us to liability claims and adversely
affect PowerSpring because Internet industries are susceptible to Year 2000
problems due to their reliance on computer hardware and software. Our potential
areas of exposure to Year 2000 issues include products purchased from third
parties, computers, software, telephone systems and other equipment used
internally. These Year 2000 problems could materially and adversely affect our
business.


                                       27
<PAGE>   30
         To date, we have not experienced any known material adverse effects on
our current products and services or internal systems or of the products,
services or systems or our suppliers, customers and third parties with whom we
do significant business as a result of the Year 2000 issue. In addition, the
total cost of our Year 2000 compliance activities has not been material to our
results of operations. However, some Year 2000 problems could arise later in
2000 or not be currently detectable. We cannot assure you that the Year 2000
issue will not have a material adverse effect on our business.

         FROM TIME TO TIME, WE ARE SUBJECT TO LAWSUITS THAT, IF THEY ARE
         SUCCESSFULLY PROSECUTED AGAINST US, COULD MATERIALLY AND ADVERSELY
         AFFECT OUR BUSINESS

         We are defendants to a pending action filed in 1993 in Denver District
Court in which the plaintiff is seeking $420,000 in damages plus punitive
damages. We believe the allegations against us are without merit. We have
vigorously contested these allegations, and we have asserted counterclaims
against the plaintiff. In 1997, the Denver District Court entered a summary
judgment in favor of us, but the summary judgment was reversed in February 1999
by the Colorado Court of Appeals. This action is currently scheduled for trial
in the third quarter of 2000. We are also from time to time involved in routine
litigation incidental to our business, although currently there is no other
pending, or to our knowledge threatened, material legal proceedings. Although we
do not currently expect any legal proceedings to have a material and adverse
affect on us, we recognize that the outcome of litigation is inherently
uncertain. Therefore, we cannot assure you that present or future litigation
could not materially and adversely affect our business.

         WE FACE SOME RISKS THAT ARE INHERENT IN NATURAL GAS OPERATIONS

         Some of our operations are subject to the hazards and risks inherent of
the servicing and operation of natural gas assets, including encountering
unexpected pressures, explosions, fire, natural disasters, blowouts, cratering
and pipeline ruptures, which could result in personal injuries, loss of life,
environmental damage and other damage to our properties and the properties of
others. These operations involve numerous financial, business, regulatory,
environmental, operating and legal risks. Damages occurring as a result of these
risks may give rise to product liability claims against us. We have product
liability insurance generally providing up to $6 million coverage per occurrence
and $7 million annual aggregate coverage. Although we believe that our insurance
is adequate and customary for companies of our size that are engaged in
operations similar to ours, losses due to risks and uncertainties could occur
for uninsurable or uninsured risks or could exceed our insurance coverage.
Therefore, the occurrence of a significant adverse effect that is not fully
covered by insurance could have a material and adverse effect on our business.
In addition, we cannot assure you that we will be able to maintain adequate
insurance in the future at reasonable rates.

         WE COULD BECOME SUBJECT TO BURDENSOME GOVERNMENT REGULATION WHICH
         AFFECTS OUR ABILITY TO OFFER OUR PRODUCTS AND SERVICES WHICH AFFECTS
         DEMAND FOR OUR PRODUCTS AND SERVICES

         Our business operations are subject to varying degrees of federal,
state, local and foreign laws and regulations. The modification or adoption of
future laws and regulations could adversely affect our business and our ability
to continually modify or alter our methods of operations at reasonable costs. We
cannot assure that we will be able, for financial or other reasons, to comply
with all applicable laws and regulations. If we fail to comply with these laws
and regulations, we could become subject to substantial penalties which could
materially and adversely affect our business.

         OUR BUSINESS WILL SUFFER IF WE ARE UNABLE TO CONTINUE TO ATTRACT AND
         RETAIN KEY MANAGEMENT AND TECHNICAL PERSONNEL

         We believe our future success will depend in large part upon our
ability to attract and retain highly qualified technical, managerial, sales and
marketing, finance and operation personnel. In particular, we will need to hire
highly qualified personnel for PowerSpring, including a chief executive officer,
a chief financial officer and an information technology officer. Competition for
qualified personnel is intense, and we cannot assure you that we will be able to
attract and retain these key employment in the future. We do not maintain key
person life insurance policies for any key members of our management team. The
loss of the services of one or more of our key

                                       28
<PAGE>   31
personnel could have a material adverse effect on our business. We cannot assure
you that we will be able to retain our current key personnel or that we will be
able attract or retain other highly qualified personnel in the future. We have
from time to time in the past experienced, and we expect to continue to
experience in the future, difficulty in hiring and retaining highly skilled
employees with appropriate qualifications. A shortage in the number of trained
technical and marketing personnel could limit our ability to increase sales of
our existing products and services and launch new product and service offerings,
including in our PowerSpring business. We do not have long-term employment
agreements with any of our key personnel, other than with W. Phillip Marcum, our
President and Chief Executive Officer, A. Bradley Gabbard, our Executive Vice
President and Chief Financial Officer, and John A. Harpole, PowerSpring's
Executive Vice President and Chief Operating Officer.

         OUR BUSINESS COULD SUFFER IF WE CANNOT MAINTAIN AND EXPAND OUR CURRENT
         STRATEGIC ALLIANCES AND DEVELOP NEW ALLIANCES

         A key element of our business strategy is the formation of corporate
relationships such as strategic alliances with other companies to provide
products and services to existing and new markets and to develop new products
and services and enhancements to existing products and services. We believe that
our success in the future in penetrating new markets will depend in large part
on our ability to maintain these relationships and to cultivate additional or
alternative relationships. However, we cannot assure you that we will be able to
develop new corporate relationships, or that these relationships will be
successful in achieving their purposes. Our failure to continue our existing
corporate relationships and develop new relationships could materially and
adversely affect our business.

         AS A RESULT OF THEIR BENEFICIAL OWNERSHIP OF A LARGE PERCENTAGE OF OUR
         COMMON STOCK, OUR DIRECTORS, EXECUTIVE OFFICERS AND SIGNIFICANT
         STOCKHOLDERS COULD EXERT SIGNIFICANT INFLUENCE OVER MATTERS REQUIRING
         STOCKHOLDER VOTES

         As of March 15, 2000, our executive officers, directors and 5% or
greater stockholders beneficially owned, in the aggregate, approximately 54.7%
of our outstanding Common Stock, assuming they exercise or convert all stock
options, warrants and other rights exercisable within 60 days of that date. As a
result, these stockholders could, as a practical matter, be able to exercise
significant control over matters requiring approval by our stockholders,
including the election of directors and the approval of mergers, sales of
substantially all of our assets and other significant corporate transactions.
The interests of these stockholders may differ from the interests of other
stockholders. In addition, this concentration of stock ownership may have the
effect of delaying or preventing a change in control of us.

         VIRTUALLY ALL OF OUR SHARES ARE ELIGIBLE FOR FUTURE SALE BY OUR CURRENT
         STOCKHOLDERS, AND SIGNIFICANT SALES OF THESE SHARES COULD RESULT IN A
         DECLINE IN OUR STOCK PRICE

         If our stockholders sell a significant number of shares of our Common
Stock in the public market, including shares issuable upon the exercise of
outstanding options, warrants and other rights, or if there is a perception that
these sales could occur, then the market price of our Common Stock could fall.
These sales also might make it more difficult for us to sell equity securities
in the future at a time and price that we deem appropriate.

         On March 15, 2000, 5,003,678 shares of Common Stock were outstanding.
On the same date, options to purchase 472,397 shares of Common Stock were
outstanding, and shares acquired upon exercise of these stock options are
eligible for sale on the public market from time to time subject to vesting.
These stock options generally have exercise prices significantly below the last
reported sale price of the Common Stock as reported on the cover of this
prospectus. On the same date, 7,000 shares of Series B Preferred Stock
convertible into 1,179,762 shares of Common Stock, and warrants and other rights
to purchase 1,946,990 shares of Common Stock, were outstanding. Virtually all
shares underlying these warrants and other rights are covered by registration
rights. The possible sale of a significant number of these shares issuable upon
the exercise of options and warrants could cause the price of the Common Stock
to decline.

         PROVISIONS OF OUR SECOND RESTATED CERTIFICATE OF INCORPORATION, BY-LAWS
         AND STOCKHOLDER RIGHTS PLAN, AND OF DELAWARE LAW, CONTAIN ANTI-TAKEOVER
         MEASURES THAT COULD DISCOURAGE A THIRD-PARTY ACQUISITION OF OUR COMMON
         STOCK AT A PREMIUM TO THE MARKET PRICE


                                       29
<PAGE>   32
         Some provisions in our Second Restated Certificate of Incorporation
("Second Restated Certificate"), our Amended and Restated By-Laws ("By-Laws"),
and our stockholder rights plan, as well as some provisions of Delaware law,
could make it more difficult for a third party to acquire us or discourage a
third party from attempting to acquire us, even if doing so would be beneficial
to stockholders. These provisions could also limit the price that investors
might be willing to pay in the future for shares of our Common Stock. These
provisions include:

         -        a classified Board of Directors in which only approximately
                  1/3 of the total board members are elected at each annual
                  meeting;

         -        authority for our Board of Directors to issue Common Stock and
                  Preferred Stock, and to determine the price, voting and other
                  rights, preferences, privileges and restrictions of
                  undesignated shares of Preferred Stock, without any vote by or
                  approval of our stockholders (other than the consent of
                  holders of Series B Preferred Stock relating to any senior or
                  equal ranking securities);

         -        the existence of large amounts of authorized but unissued
                  shares of Common Stock and Preferred Stock;

         -        super-majority voting requirements to effect material
                  amendments to our Second Restated Certificate and By-Laws;

         -        limitations on the persons who may call special meetings of
                  stockholders;

         -        prohibiting stockholder action by written consent;

         -        our stockholders rights plan;

         -        a fair price provision that sets minimum price requirements
                  for potential acquirers;

         -        anti-greenmail provisions which limit our ability to
                  repurchase shares of Common Stock from significant
                  stockholders;

         -        restrictions under Delaware law on mergers and other business
                  combinations between us and any 15% stockholders; and

         -        advance notice requirements for director nominations and for
                  stockholder proposals.

         WE DO NOT INTEND TO PAY DIVIDENDS ON THE COMMON STOCK, AND OUR ABILITY
         TO PAY DIVIDENDS ON THE COMMON STOCK IS LIMITED

         We have never declared or paid any cash dividends on our Common Stock.
Therefore, a stockholder will not experience a return on its investment in our
Common Stock without selling its shares, because we currently intend on
retaining any future earnings to fund our growth and do not expect to pay
dividends in the foreseeable future on the Common Stock.

         Under Delaware law, we are not permitted to make a distribution to our
stockholders, including dividends on our capital stock, if, after giving effect
to the payment, we would not be able to pay our debts as they become due in the
usual course of business or if our total assets would be less than the sum of
our total liabilities plus the amount which would be needed if we were to be
dissolved at the time of the distribution, to satisfy the preferential rights
upon dissolution of stockholders whose preferential rights are superior to those
receiving the distribution. Consequently, if we fail to meet these criteria, we
will be unable to pay dividends on the Series B Preferred Stock.

         Our ability to pay dividends on our Common Stock is restricted by our
current credit facility. If we fail to pay dividends on the Series B Preferred
Stock, we will be prohibited from paying dividends on the Common Stock until all
unpaid dividends on the Series B Preferred Stock have been paid in full. In the
future, our Board of Directors will determine whether we pay dividends on the
Series B Preferred Stock or on our Common Stock. We cannot assure you that we
will pay dividends on the Series B Preferred Stock or on our Common Stock.



                                       30
<PAGE>   33
         OUR STOCK PRICE IS SUBJECT TO EXTREME PRICE AND VOLUME FLUCTUATIONS

         The market price and volume of the Common Stock has in the past been,
and in the future is likely to continue to be, highly volatile. The stock market
in general has been experiencing extreme price and volume fluctuations for
years. The market prices of securities of technology companies and
Internet-related companies in particular have been especially volatile. We
cannot assure you that our Common Stock will continue to trade at recent price
and volume levels. The following factors could cause wide fluctuations in the
market price and trading volume of our Common Stock in the future:

         -        actual or anticipated variations in our results of operations;

         -        announcements of technological innovations;

         -        changes in, or the failure by us to meet, securities analysts'
                  estimates and expectations;

         -        introduction of new products and services by us or our
                  competitors;

         -        conditions or trends in the energy services and information
                  industries in general and in the Internet and other technology
                  industries in particular;

         -        announcements by us or our competitors of significant
                  technical innovations, contracts, acquisitions, strategic
                  relationships, joint ventures or capital commitments;

         -        announcements by us or our competition of the success or
                  status of our business;

         -        general market conditions;

         -        additions or departures of our key personnel;

         -        sales of our Common Stock by directors, executive officers and
                  significant stockholders; and

         -        the gain or loss of significant customer orders.

         Many of these factors are beyond our control. These factors may
decrease the market price of our Common Stock, regardless of our operating
performance.

         In addition, broad fluctuations in price and volume have been unrelated
or disproportionate to operating performance, both of the market in general and
of us in particular. Any significant fluctuations in the future might result in
a material decline in the market price of our Common Stock. In the past,
following periods of volatility in the market price of a company's securities,
securities class action litigation has often been brought against that company.
We may become involved in this type of litigation in the future. Litigation is
often expensive and diverts management's attention and resources, which could
have a material adverse effect on our business, even if we ultimately prevail in
the litigation.

         WE MAY ISSUE ADDITIONAL PREFERRED STOCK RANKING JUNIOR TO THE SERIES B
         PREFERRED STOCK, WHICH COULD DILUTE THE INTERESTS OF HOLDERS OF COMMON
         STOCK

         The terms of the Series B Preferred Stock do not limit the issuance of
additional series of Preferred Stock ranking junior to the Series B Preferred
Stock, but do require the approval of the holders of a majority of the
outstanding shares of Series B Preferred Stock to issue any stock senior to or
on a parity with the Series B Preferred Stock. The issuance of additional shares
of Preferred Stock ranking junior to the Series B Preferred Stock could dilute
the interest of holders of our Common Stock.

ITEM 2. DESCRIPTION OF PROPERTY

         We lease our principal executive offices located in downtown Denver,
Colorado. The leased space contains 3,443 square feet. The lease currently has a
monthly rental obligation of $4,906, including operating costs, expires July 31,
2001, and contains a market-rate renewable lease provision.

         Metretek Florida leases its principal business offices, located in
Melbourne, Florida, for its executive, manufacturing, engineering, warehouse and
marketing operations. This facility has 50,000 square feet and a current

                                       31
<PAGE>   34
monthly rental obligation of $29,856, including operating costs. The lease
expires July 30, 2005. Metretek Florida has sub-leased 2,380 square feet of its
space for $1,896 monthly rental.

         Southern Flow leases office facilities in the following locations:
Lafayette, Belle Chasse and Shreveport, Louisiana; Jackson, Mississippi; Houston
and Victoria, Texas; Tulsa, Oklahoma; and Aztec, New Mexico. These offices have
an aggregate of approximately 66,000 square feet, total monthly rental
obligations of approximately $31,000 and terms expiring at various times through
2001. In addition, Southern Flow owns and occupies land and a 8,600 square foot
office building in Dallas, Texas.

         PowerSpring leases its principal business office located in downtown
Denver, Colorado. The leased space contains 2,902 square feet. The lease
currently has a monthly rental obligation of $4,540 and expires January 31,
2004. PowerSpring intends to lease additional office space during 2000 to
accommodate its anticipated growth needs, although we cannot assure you that any
new leases will be on terms favorable to us.


ITEM 3. LEGAL PROCEEDINGS

         In 1993, a former employee filed a lawsuit in Denver District Court
against us and DVCO Fuel Systems, Inc. ("DVCO"), one of our former subsidiaries,
alleging that we conspired with third parties to defraud him and that we
intentionally interfered with contracts in which he had an interest. The former
employee is seeking damages in the amount of approximately $420,000 plus
punitive damages. We have denied the former employee's claims and have asserted
counterclaims against the former employee, alleging that (1) he breached an
agreement with us which included a legal release, (2) he made intentional and/or
negligent misrepresentations regarding his qualification and reputation in the
compressed natural gas industry, (3) he breached his fiduciary duty to us, and
(4) he disparaged us. On September 18, 1997, the Denver District Court granted
our motion for summary judgment in our favor as to all claims of the former
employee. On February 18, 1999, the Colorado Court of Appeals reversed the
summary judgment decision and remanded the lawsuit for trial as to the
conspiracy claim only. The Colorado Supreme Court has upheld the Colorado Court
of Appeals' ruling. As a result, the lawsuit is scheduled for trial in August
2000. We believe the allegations against us are without merit and intend to
vigorously defend the claims made against us in the lawsuit. Although the
ultimate outcome of litigation is inherently uncertain, in the opinion of
management, this lawsuit is not expected to have a material adverse effect on
our business, financial condition or results of operations.

         From time to time, we are involved in routine litigation incidental to
our business. However, other than as set forth above, no legal proceedings are
currently pending or have been overtly threatened against us that we expect,
based upon current information, to have a material adverse effect on our
business, financial condition or results of operations.

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

         At a special meeting of stockholders held on February 3, 2000, in
connection with the Units Private Placement, the following proposals were
submitted to and approved by our stockholders:

         Proposal 1: To approve and ratify:

                  -        the issuance and sale in a private placement of (a)
                           up to 1,400,000 shares of Common Stock, (b) up to
                           7,000 shares of Series B Preferred Stock, and (c)
                           Unit Warrants to purchase up to 700,000 shares of

ITEM 5. MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS


         Our Common Stock is traded on the Nasdaq National Market under the
symbol "MTEK." Our Dividend Warrants, which were issued as a dividend to
stockholders on September 18, 1998, have been traded on the Nasdaq SmallCap
Market since such date under the symbol "MTEKW". The following table sets forth,
for the periods indicated, the range of the high and low closing sale prices, of
the Common Stock as reported on the Nasdaq National Market, adjusted to reflect
the 1-for-4 reverse split of the Common Stock effected on July 6, 1998, and of
the Dividend Warrants as reported on the Nasdaq SmallCap Market.

HOLDERS

         As of March 15, 2000, there were 281 holders of record of the Common
Stock and 278 holders of record of the Dividend Warrants. Because many of the
shares of Common Stock are held by brokers and other institutions on behalf of
stockholders, we are unable to determine precisely the total number of
stockholders represented by these record holders but estimates, based upon
available information, that there are at least 3,000 beneficial owners of its
Common Stock.

DIVIDENDS

         We have never declared or paid cash dividends on our Common Stock, and
do not anticipate declaring or paying any cash dividends on the Common Stock in
the foreseeable future. We currently intend to retain all future earnings, if
any, for use in the operation of our business. In addition, the terms of our
credit facility prohibit the payment of dividends (other than on the Series B
Preferred Stock) without the consent of our lender, and the terms of our Series
B Preferred Stock contain certain restrictions on our ability to pay dividends
on our Common Stock. Future dividends, if any, will be determined by our Board
of Directors, based upon our earnings, financial condition, capital
requirements, charter restrictions, contractual restrictions and such other
factors as our Board of Directors deems relevant.

         Holders of Series B Preferred Stock are entitled to receive dividends
in cash at the rate of 8% per annum, which dividends may be paid or accrued,
plus any additional dividends declared by the Board of Directors, and are
entitled, under specified circumstances, to participate in dividends declared or
paid on the Common Stock.

RECENT SALES OF UNREGISTERED SECURITIES

         On February 4, 2000, we completed the Units Private Placement,
consisting of 7,000 Units (including 1,450 Units issued December 9, 1999) issued
to institutional investors and other "accredited investors" (as such term is
defined Rule 501 of Regulation D under the Securities Act) for total gross
proceeds of $14 million. Each Unit consisted of 200 shares of Common Stock, one
share of Series B Preferred Stock and Unit Warrants to purchase 100 shares of
Common Stock.

         Each share of Series B Preferred Stock will be convertible, in whole or
in part, at any time after June 9, 2000 at the option of the holder, into that
number of shares of Common Stock equal to the "conversion value" of

                                       34
<PAGE>   37
such share of Series B Preferred Stock, which is $1,000 per share, plus
accumulated and unpaid dividends on such share, divided by the then applicable
"conversion price" of the Series B Preferred Stock. The initial conversion price
of the Series B Preferred Stock is $5.9334 per share of Common Stock. Based upon
an initial conversion value of $1,000, each share of Series B Preferred Stock is
initially convertible into 168.5374 shares of Common Stock. The conversion price
is subject to adjustment upon the following events:

         -        If, on December 9, 2000, the "reset price", computed by
                  multiplying 110% by the sum of (1) the average closing bid
                  price of the Common Stock for the 30 trading days immediately
                  preceding this date, plus (2) the fair market value of any
                  securities, cash or assets (other than any dividend or
                  distribution paid exclusively in cash or in Common Stock)
                  distributed or made payable to the holders of Series B
                  Preferred Stock on an as-converted per share basis, is less
                  than the then applicable conversion price, then the conversion
                  price of the Series B Preferred Stock will be reduced to the
                  reset price, provided that the conversion price cannot be
                  reduced by more than 50%;

         -        Issuances, sales or exchanges of shares of Common Stock at a
                  price per share of Common Stock, or issuances of option,
                  warrants or rights to subscribe for shares of Common Stock or
                  securities convertible into exchangeable shares of Common
                  Stock, at a purchase price less than the greater of the
                  "market price" of the Common Stock or the conversion price of
                  the Series B Preferred Stock in effect immediately before such
                  issuance, sale or exchange, which specified exceptions for
                  employee stock option programs and outstanding warrants;

         -        Subdivision, combination, split-ups, reverse splits,
                  reclassifications or similar corporate transactions;

         -        Any dividend payable in shares of Common Stock; or

         -        Any merger, consolidation or sale of all or substantially all
                  of our properties and assets;

         Each Unit Warrant entitles the holder to purchase one share of Common
Stock at an initial exercise price of $6.7425 per share. The initial exercise
price of the Unit Warrants will be reset on December 9, 2000 to 125% of the
average closing bid price of the Common Stock for the 30 trading days
immediately preceding such date, if the computed average closing bid price is
less than the exercise price of the Unit Warrants then in effect. The exercise
price is subject to further adjustment under the anti-dilution provisions of the
Unit Warrants, which are substantially the same as the anti-dilution provisions
of the Series B Preferred Stock described above. The Unit Warrants can be
exercised at any time until December 9, 2004. Instead of paying the exercise
price in cash, holders of Units Warrants may exercise their Unit Warrants by
delivering to us shares of Common Stock with the fair market value equal to the
exercise price. Alternatively, holders of Units Warrants may make a "cashless"
exercise of the Unit Warrants and receive, upon exercise without making any
payment of cash, Common Stock or any other asset, a "net" number of shares of
Common Stock determined by formula based on the amount that the trading price of
the Common Stock exceeds the exercise price then in effect.

         In connection with the Units Private Placement, we engaged First Albany
Corporation ("First Albany") to serve as our exclusive placement agent. We paid
First Albany a fee equal to 2% of the gross proceeds, plus customary fees and
expenses, and issued to First Albany and its affiliates warrants to purchase
30,000 shares of Common Stock at an exercise price of $14.50 per share,
exercisable from date of grant for four years.

         On November 10, 1999, as a royalty payment to a licensor under a
license agreement, we issued 9,127 shares of Common Stock to the licensor.

         Each of the issuances of securities described above was made in
reliance upon an exemption from the registration requirements of the Securities
Act pursuant to Section 4(2) of the Securities Act as a transaction not
involving a public offering. We reasonably believe that each recipient of such
securities had such knowledge and experience in financial and business matters
to be capable of evaluating the risks and merits of the investment, and each
recipient represented its intention to acquire the securities for investment
purposes only and not with a view to or for the sale in connection with any
unregistered distribution thereof. All recipients had adequate access, through
contractual provisions and/or their relationships with us, to information about
us, our business and operations, and

                                       35

the securities. In connection with those issuances of securities, appropriate
legends were affixed to the certificates issued in such transactions.


ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

INTRODUCTION

         The following discussion and analysis of our results of operations for
the years ended December 31, 1999 and 1998 and of our consolidated financial
condition as of December 31, 1999 should be read in conjunction with our
consolidated financial statements and related notes included elsewhere in this
Report.

         We recently formed two subsidiaries to develop and operate our
Internet-based energy information and services business, PowerSpring and
TotalPlan. TotalPlan was merged into PowerSpring in March 2000. Neither
PowerSpring nor TotalPlan had any revenues during the year ended December 31,
1999.

         This discussion contains forward-looking statements within the meaning
of Section 27A of the Securities Act and Section 21E of the Exchange Act. We may
identify these statements by the use of words such as "may", "could", "should",
"will", "project", "continue", "estimate", "believe", "expect", "anticipate",
"intend", "plan" and similar expressions. These forward-looking statements
involve several risks and uncertainties. Our actual results could differ
materially from those anticipated in these forward-looking statements as a
result of various factors, including those we discuss in "Item I. Description of
Business -- Additional Factors That Could Affect Our Business and Future
Results", and elsewhere in this Report. These forward-looking statements speak
only as of the date of this Report, and we caution you not to rely on these
statements without also considering the risks and uncertainties associated with
these statements and our business that are addressed in this Report.


RESULTS OF OPERATIONS

</TABLE>


       We currently have three reportable business segments: automated energy
data management; natural gas measurement services; and Internet-based energy
information and services. The operations of our automated energy data management
segment are conducted by Metretek Florida. Metretek Florida's manufactured
products fall into three categories: remote data collection products; electronic
corrector products; and application-specific products. Metretek Florida also
provides energy data collection and management services and post-sale support
services for its manufactured products.

       The operations of our natural gas measurement services segment are
conducted by Southern Flow. Southern Flow's services include on-site field
services, chart processing and analysis, laboratory analysis, and data
management and reporting. These services are provided principally to customers
involved in natural gas production, gathering, transportation and processing.

       The operations of our Internet-based energy information and services
segment are conducted by PowerSpring. PowerSpring has incurred operating costs
to date and does not expect to commence revenue generating operations until the
second quarter of 2000.

       We evaluate the performance of our operating segments based on income
(loss) before taxes, nonrecurring items and interest income and expense. Other
profit (loss) amounts in the table above include corporate related items,
results of insignificant operations, and income and expense not allocated to its
operating segments.

       During 1998, we decided to discontinue our business segment engaged in
acquiring or financing the acquisition of natural gas assets through private
programs. The financial statements as of and for the year ended December 31,
1998 have been reclassified to exclude the operating results of this segment
from continuing operations and to account for this segment as discontinued
operations. The following discussion relates only to our continuing operations.

YEAR ENDED DECEMBER 31, 1999 COMPARED TO YEAR ENDED DECEMBER 31, 1998

         Revenues. Our consolidated revenues for the year ended December 31,
1999 decreased $556,914, or 3%, compared to the same period in 1998, due to a
decrease in revenues by Metretek Florida. Metretek Florida's revenues for the
year ended December 31, 1999 decreased $540,767, or 6%, compared to the same
period in 1998. A decrease in Metretek Florida's international sales by $726,782
was partially offset by an increase in Metretek Florida's domestic sales by
$186,015. International sales, which are subject to fluctuation because Metretek
Florida does not currently have a steady base of international customers,
decreased because Metretek Florida did not capture as many new international
projects during 1999 as compared to 1998. The increase in Metretek Florida's
domestic sales was primarily the result of the inclusion in its 1999 revenues of
sales of its electronic corrector product line, which it acquired from American
Meter in May 1998 but did not fully market until the mid-third quarter of 1998.
Domestic sales of Metretek Florida's traditional line of remote data collection
products and systems also increased slightly during 1999 due primarily to
increased demand for Year 2000 compliant systems, but this was more than offset
by a decrease in circuit board assembly sales resulting partially from reduced
industry demand and partially from a loss of circuit board assembly business by
Metretek Florida due to sales personnel changes. A comparison of Metretek
Florida's current domestic and international product mix is as follows:

Southern Flow's revenues increased $6,526, or less than 1%, for the year ended
December 31, 1999, compared to the same period in 1998.

         Costs and Expenses. Costs of measurement sales and services include
materials, labor, personnel and related overhead costs incurred to manufacture
products and provide services. Cost of sales and services for the year ended
December 31, 1999 increased $895,946, or 7%, compared to the same period in
1998. Metretek Florida's cost of sales and services for the year ended December
31, 1999 increased $1,098,406, or 26%, compared to the same period in 1998. This
increase was due primarily to higher personnel and related overhead costs
associated with the integration and manufacturing of the electronic corrector
product line which was acquired by Metretek Florida in May 1998. As a result,
Metretek Florida's overall gross profit margin decreased from 52.1% to 35.6%
compared to the same period in 1998. Southern Flow's cost of sales and services
for the year ended December 31, 1999 decreased $202,460, or 2%, compared to the
same period in 1998. Southern Flow's gross profit margin for the year ended
December 31, 1999 increased slightly from 22.0% to 23.9% compared to the same
period in 1998, which is within the range of normal fluctuations.

         General and administrative expenses include personnel and related
overhead costs for support and administration functions. General and
administrative expenses for the year ended December 31, 1999 decreased $139,785
or 4%, compared to the same period in 1998, due principally to the effect of the
following factors: (1) a decrease in expenses of Metretek Florida of
approximately $51,000 attributable to overall cost savings at Metretek Florida
and Sigma VI resulting from combining certain administrative functions; (2)
decreases in general and corporate expenses of approximately $184,000 primarily
due to the elimination of compensation costs associated with our 1998 Employee
Stock Purchase Plan, which was terminated in July 1998; and (3) a decrease in
expenses of Southern Flow of approximately $32,000 primarily attributable to
reduced state and franchise taxes in 1999 compared to 1998. These decreases in
general and administrative expenses were partially offset by approximately
$127,000 of personnel and related overhead costs incurred by PowerSpring, for
which there were no comparable costs during the same period in 1998.

         Selling, marketing and service expenses consist of personnel and
related overhead costs, including commissions for the sale and marketing
activities, together with advertising and promotion costs. Selling, marketing
and service expenses for the year ended December 31, 1999 increased $532,396, or
35%, compared to the same period in 1998, approximately $349,000 of which
related to activities at Metretek Florida. The increase in Metretek Florida's
expenses was due principally to an increase in the number of sales and customer
service personnel in 1999 compared to the same period in 1998 primarily
associated with the integration of the electronic corrector product line. The
remaining increase in selling, marketing and service expense of approximately
$183,000 in 1989 was incurred by PowerSpring, for which there were no comparable
costs during the same period in 1998.

         Depreciation and amortization expenses include the depreciation and
amortization of real property, customer list, goodwill and capitalized software
development costs. Depreciation and amortization expenses for the year ended
December 31, 1999 increased $159,433, or 14%, compared to the same period in
1998. This increase was due to additional goodwill amortization costs related to
Metretek Florida's acquisitions in the second quarter of 1998 as well as
increased depreciation expenses at both Metretek Florida and Southern Flow.

         Research and development expenses include payments to third parties,
personnel and related overhead costs for product and service development,
enhancements, and upgrades. Research and development expenses for the year ended
December 31, 1999 increased $1,264,375, or 132%, compared to the same period in
1998. The increase is due primarily to PowerSpring development expenditures in
1999 of approximately $1,196,000, for which there were no comparable costs
during the same period in 1998.

         Interest, finance charges and other expenses include interest and
finance charges on our credit facility as well as other non-operating expenses.
Interest, finance charges and other expenses for the year ended December 31,
1999 increased $101,331, or 55%, compared to the same period in 1998. The
increase reflects interest expense on additional borrowings during much of 1999
compared to 1998 in order to fund Metretek Florida's growth and development of
the businesses acquired by Metretek Florida in 1998, borrowings to finance
increases in Metretek Florida's inventory and accounts receivable, borrowings to
finance the initial development efforts of PowerSpring, and the amortized
portion of capitalized finance charges incurred in 1998 to obtain our current
credit facility.

SEASONALITY AND CYCLICALITY

         Metretek Florida historically derives substantially all of its revenues
from sales of its products and services to the utility industry. Metretek
Florida has experienced variability of operating results on both an annual and a
quarterly basis due primarily to utility purchasing patterns and delays of
purchasing decisions as a result of mergers and acquisitions in the utility
industry and changes or potential changes to the federal and state regulatory
frameworks within which the utility industry operates. The utility industry,
both domestic and foreign, is generally characterized by long budgeting,
purchasing and regulatory process cycles that can take up to several years to
complete. Metretek Florida's utility customers typically issue requests for
quotes and proposals, establish committees to evaluate the purchase, review
different technical options with vendors, analyze performance and cost/benefit
justifications and perform a regulatory review, in addition to applying the
normal budget approval process within a utility. Purchases of Metretek Florida's
products are, to a substantial extent, deferrable in the event that utilities
reduce capital expenditures as a result of mergers and acquisitions, pending or
unfavorable regulatory decisions, poor revenues due to weather conditions,
rising interest rates or general economic downturns, among other factors.

         Based upon the discussion and analysis in this Item and in "Item 1.
Description of Business -- Additional Factors That Could Affect Our Business and
Future Results," we believe that our future revenues, expenses and results of
operations are likely to vary significantly from quarter to quarter. As a
result, quarterly comparisons of operating results are not necessarily
meaningful or indicative of future performance.

FINANCIAL CONDITION AND LIQUIDITY

         We require capital principally for (1) the financing of inventory and
accounts receivable, (2) research and development expenses, including the
development of PowerSpring, (3) capital expenditures for property and equipment
and software development, and (4) the funding of possible future acquisitions.

         Net cash used by operating activities was approximately $396,000 for
the year ended December 31, 1999, which was the net result of the following: (1)
approximately $2,281,000 of cash used to fund continuing operations, before
changes in assets and liabilities; (2) approximately $1,891,000 of cash provided
by changes in working capital and other asset and liability accounts; and (3)
approximately $6,000 of cash used by discontinued operations.

         We plan to continue and expand our research and development efforts to
enhance our existing products and services, and to develop new products,
especially in the business of PowerSpring. We anticipate that our research and
development costs in 2000 will be approximately $4,700,000 of which $1,200,000
will relate to Metretek's business and $3,500,000 is expected to be incurred in
connection with further developing PowerSpring. Research and development
expenses in the amount of $2,225,758 were incurred in the year ended December
31, 1999.


                                       39
<PAGE>   42
         We anticipate capital expenditures in 2000 of approximately $8,100,000,
primarily for computer software and hardware production and laboratory
equipment. Capital expenditures for the year ended December 31, 1999 totaled
$300,298.

         On April 14, 1998, we entered into a loan and security agreement (the
"Loan Agreement") with a commercial bank (the "Lender") providing for a combined
$5,000,000 credit facility consisting of loans (the "Loans") and letters of
credit subject to limitations described below. The Loan Agreement provides for
daily advances in the form of Loans to fund capital requirements, and daily
paydowns on outstanding balances of the Loans from collection of customer
accounts receivable. We make monthly interest payments computed at prime plus 1%
(9.5% at December 31, 1999) on outstanding balances of the Loans. The Loans
mature on March 14, 2001.

         The Loans are secured by our tangible and intangible assets, including
the equipment, inventory, receivables and cash deposits, and the pledge of the
shares of our subsidiaries. The Loan Agreement requires us to maintain a minimum
tangible net worth, a maximum debt to tangible net worth ratio, minimum annual
net income (or maximum annual net loss in 1999), a minimum debt service coverage
ratio, and contains other standard covenants related to our operations,
including prohibitions on the payment of dividends and the issuance or
repurchase of securities (with certain exceptions) without the Lender's consent.

         Borrowings on the Loans are limited to the sum of 80% of eligible
accounts receivable of Southern Flow and Metretek Florida and 50% of raw
materials and finished goods inventory (up to a combined maximum of
$1,500,000) of Southern Flow and Metretek Florida. At December 31, 1999, we had
a combined $3,587,864 Loan availability, of which $269,968 had been borrowed by
Southern Flow and Metretek Florida, leaving $3,317,896 in unused Loan
availability.

         On May 4, 1998, we acquired substantially all of the assets and
business of a subsidiary of American Meter Company pertaining to electronic
correctors and non-radio-frequency meter reading devices in the natural gas and
electric utility industry. In consideration for this purchase, we delivered to
American Meter an aggregate purchase price consisting of $1,300,000 in cash,
439,560 unregistered shares of Common Stock, and a $600,000 convertible
subordinated promissory note. In March 2000, American Meter converted the note
into 105,495 shares of Common Stock under the terms of the note. Until it was
converted, the note bore interest on the unpaid principal balance at a fixed
rate equal to 7.5% per annum, payable quarterly in arrears, and was due and
payable on May 4, 2002.

         On September 13, 1999, we entered into a strategic relationship with
Scient to assist us in designing and creating an Internet-based business to
enable us to take its measurement information products, services, and data
measurement technologies to the market of end-users of natural gas and
electricity. The Internet project is being developed and operated through
PowerSpring. In connection with the development of PowerSpring, we issued to
Scient a warrant to purchase 125,000 shares of Common Stock. The Scient Warrant
becomes exercisable in September 2000, at exercise prices split between $5.00
and $10.00 per share, and expires in September 2002. Scient has registration
rights with respect to the Common Stock issuable upon the exercise of the Scient
warrant.

         In order to fund the initial development of PowerSpring, we entered
into an amendment with the Lender (the "Loan Amendment") to the terms of the
Loan Agreement. The Loan Amendment amended certain covenants of the Loan
Agreement, including our minimum annual net income (or maximum annual net loss
in 1999), minimum tangible net worth and minimum debt service coverage ratio.
The Loan Amendment also permitted us to utilize up to $700,000 of the credit
facility to finance expenditures on the first phase of PowerSpring's
development. In connection with the Loan Amendment, we paid customary fees to
the Lender and issued a warrant to purchase 20,000 shares of Common Stock. The
Lender warrant is exercisable for three years at an exercise price of $5.00 per
share. The Lender has registration rights with respect to the Common Stock
issuable upon the exercise of the Lender warrant.


                                       40
<PAGE>   43
         We estimate that this initial development phase and launch of
PowerSpring will require aggregate expenditures of between $6,000,000 and
$8,000,000, consisting of consulting fees and expenses payable to Scient and
costs of acquiring the requisite technology, including hardware and software, as
well as research and development costs. Through December 31, 1999, these costs
were approximately $1.5 million.

         On February 4, 2000, we completed the $14,000,000 Units Private
Placement by issuing 7,000 Units, including 1,450 Units we issued on December 9,
1999. Each Unit consisted of 200 shares of Common Stock, 1 share of Series B
Preferred Stock and Unit Warrants to purchase 100 shares of Common Stock. For a
description of the material terms of these securities, see "Item 5. Market for
Common Equity and Related Stockholder Matters - Recent Sales of Unregistered
Securities." In the Units Private Placement, we issued 1,400,000 shares of
Common Stock, 7,000 shares of Series B Preferred Stock and Unit Warrants to
purchase 700,000 shares of Common Stock. The Units Private Placement was
approved and ratified by our stockholders at a special meeting of stockholders
held on February 3, 2000. The Units were issued to institutional investors and
other "accredited investors" (as defined under Regulation D under the Securities
Act). The primary purpose of the Units Private Placement was to raise capital to
enable us to develop the Internet-based business of PowerSpring. A portion of
the proceeds was also used to repay outstanding indebtedness, and the remaining
proceeds will be used for general corporate and working capital purposes,
including potentially providing the funds to finance an acquisition opportunity,
if one were to arise.

         On March 17, 2000, we acquired Mercator Energy Incorporated through a
merger of Mercator with a wholly-owned subsidiary of PowerSpring. Mercator is a
Denver-based natural gas services and brokerage company that acts as an
independent broker-agent for both producers and consumers of natural gas. In
consideration for the acquisition of Mercator, we delivered to John A. Harpole,
the President and sole shareholder of Mercator prior to the acquisition,
$408,334 in cash, a $741,666 non-negotiable promissory note payable by
PowerSpring over two years and secured by a general security interest in the
assets of PowerSpring, and 2,500,000 shares of common stock of PowerSpring.
Subsequent to the acquisition of Mercator, we own 87.5% of the outstanding
shares of PowerSpring common stock, Mr. Harpole owns 12.5% of the outstanding
shares of PowerSpring common stock, and Mercator has become a wholly-owned
subsidiary of PowerSpring. We, PowerSpring and Mr. Harpole entered into a
stockholders agreement that addresses certain rights related to Mr. Harpole's
PowerSpring common stock, including a right for Mr. Harpole to put his shares of
PowerSpring common stock back to PowerSpring at an appraised value for each
payable over three years if PowerSpring has not completed an initial public
offering or has not sold its business within two years. PowerSpring also entered
into a two-year employment agreement with Mr. Harpole, who will serve as the
Executive Vice President, Chief Operating Officer and a director of PowerSpring.
Under the employment agreement, Mr. Harpole received an option to purchase
60,000 shares of our Common Stock, exercisable at $17.88 per share, and an
option to purchase 200,000 shares of PowerSpring common stock, exercisable at
$.30 per share.

         On September 13, 1999, we entered into a consulting and joint venture
agreement with Mercator, under which Mercator provided its energy procurement
services to us on a consulting basis. In connection with our acquisition of
Mercator, we issued to Mercator a warrant to purchase 60,000 shares of Common
Stock. The Mercator warrant vests in three tranches from the date of issuance
through March 2001, with exercise prices ranging between $4.50 and $5.50 per
share, and expires in September 2002. Mercator has registration rights with
respect to the Common Stock issuable upon the exercise of the Mercator warrant.
In connection with our acquisition of Mercator, the consulting agreement, and a
related stock option agreement between TotalPlan and Mercator, were terminated,
and Mercator transferred the Mercator warrant to Mr. Harpole.

         Compensation expense for the fair value of the Scient, Mercator and
Lender warrants is being recognized in accordance with the provisions of
Statement of Financial Accounting Standards No. 123 "Accounting for Stock-Based
Compensation," over the period in which the services are being performed or the
remaining term of the Loan Agreement. Compensation expense associated with the
warrants in the amount of $70,029 has been recognized in the consolidated
statement of operations during the year ended December 31, 1999.

         In September 1998, our Board of Directors adopted a stock repurchase
plan that authorized us to purchase up to approximately 7% of our outstanding
Common Stock in open market transactions, from time to time as management deemed
appropriate, based on the market price of the Common Stock. During 1998 and


                                       41
<PAGE>   44
1999, we repurchased 96,116 shares of its Common Stock at an average price of
$2.22 per share. The stock repurchase plan was discontinued on October 6, 1999.
All of the repurchased shares have been retired.

         Based on our current plans and assumptions, management believes that
our capital resources, including cash and cash equivalents, amounts available
under existing credit facilities and funds generated from continuing operations,
and additional proceeds from the disposition of the remaining assets of its
discontinued operations, will be sufficient to meet our currently anticipated
cash needs, including our working capital needs, capital commitments and debt
service requirements, including those pertaining to the launch of the business
of PowerSpring. However, we will also have a continuing need for additional
capital to accomplish our business strategy with respect to our existing
businesses. The continued development of the business of PowerSpring will also
require substantial capital after launch. In addition, unanticipated events,
over which we may have no control, could increase our operating costs or
decrease our ability to generate revenues from product and service sales. We
will also require additional capital in the future in order to make any
significant acquisition of businesses or technologies.

         We expect that after the initial development stage of PowerSpring is
completed and our website is launched, the further development and growth of
PowerSpring, including staff, organizational and start up expenses, marketing
costs and additional capital expenditures, will require significant additional
funds, beyond the proceeds of the Units Private Placement, from the proceeds of
public or private equity financing, debt financing or from other sources. We
intend to raise any needed additional capital to fund the development and
operations of PowerSpring primarily through financing at the PowerSpring level.
However, depending upon the availability of capital, market conditions, our
consolidated operations and the operations of PowerSpring, we may also or
instead raise additional capital at the Metretek level. For example, depending
on market conditions and other factors we deem appropriate, we may call our
Dividend Warrants for redemption. Due to the trading price of our Common Stock,
as of the date of this Report we have the right, upon 30 days notice, to call
the Dividend Warrants for redemption, and we will continue to have this
redemption right as long as the closing sale price of the Common Stock as
reported on the Nasdaq National Market equals or exceeds $6.50 per share. We
expect that, subject to market conditions, most or all Dividend Warrants will be
exercised after we call them for redemption, resulting in gross proceeds of up
to $3.5 million to us.

         Obtaining additional financing will depend on many factors, including
market conditions, our operating performance and investor sentiment. Terms of
debt financing could restrict our ability to operate our business, or to expand
our operations. In addition, if we raise additional capital by issuing capital
stock or securities convertible into capital stock, stockholders could suffer a
significant dilution of their percentage ownership interests, and the new
capital stock or other new securities could have rights, preferences or
privileges senior to those of our current stockholders.

         Our capital raising will be subject to the consent of the Lender, if
our credit facility is then in effect. In addition, depending on how it is
structured, our capital raising could require the consent of the holders of our
Series B Preferred Stock. We cannot assure you that sufficient additional funds
will be available to us on a timely basis or that, if available on a timely
basis, such funds can be obtained on terms satisfactory to us, to our lender and
to the holders of our Series B Preferred Stock, if their consents are required.
Our inability to obtain sufficient additional capital on a timely basis on terms
that are acceptable could have a material adverse effect on our business,
financial condition and results of operations.

RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1998, the Financial Accounting Standards Board issued Financial
Accounting Standards Statement No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("FAS 133"). FAS 133 establishes methods of accounting
for derivative financial instruments and hedging activities related to those
instruments as well as other hedging activities. We will be required to adopt
FAS 133 for our fiscal year ending December 31, 2001. However, because we do not
utilize derivative financial instruments, we do not believe the impact of FAS
133 will be material to our financial position or results of operations.


                                       42
<PAGE>   45
         In December 1998, the AICPA issued Statement of Position 98-9,
"Modification of SOP 97-2, Software Revenue Recognition, With Respect to Certain
Transactions" ("SOP 98-9"). SOP 98-9 requires use of the "residual method" for
recognition of revenue when vendor-specific objective evidence exists for
undelivered elements but does not exist for delivered elements of a software
arrangement. We will be required to comply with the provisions of SOP 98-9 for
transactions entered into beginning January 1, 2000. The adoption of SOP 98-9 is
not expected to have a material effect on our financial position or results of
operations. However, SOP 98-9 may require more revenue to be deferred for
certain types of transactions.

YEAR 2000 COMPLIANCE

         The "Year 2000 issue," which presented potential risks and
uncertainties to virtually all businesses, was to have resulted from computer
programs that used two digits rather than four to define the applicable year.
Any computer programs that had time-sensitive software could have recognized a
date using "00" as the year 1900 rather than the year 2000. This situation could
have resulted in system failures or miscalculations causing disruptions to
operations, including, among other things, a temporary inability to process
transactions, send invoices, or engage in similar or normal business activities.

         As of the date of this Report, we have not experienced any known
material adverse impacts on our current products and services, internal
information systems or other internal operating systems as a result of the Year
2000 issue, and we have not received notice of any material Year 2000 compliance
issues from our suppliers or customers. Based on the work done to date, costs
directly associated with our Year 2000 compliance efforts were approximately
$200,000. We do not expect that any future expenditures to address the Year 2000
issues will be material. However, it remains possible that Year 2000 issues
associated with our products or systems may still arise or that we could receive
notice of Year 2000 issues that have arisen with our products and services. We
plan to continue to monitor the Year 2000 issues closely. Therefore, we cannot
assure you that Year 2000 issues will not have a material adverse effect on our
results of operations or financial condition.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Exchange Act ("Section 16(a)") requires our
directors and executive officers, and beneficial owners of more than 10% of our
outstanding Common Stock, to file initial reports of ownership on Form 3 and
reports of changes in ownership on Form 4 or Form 5 with the SEC, and to furnish
us with copies of all such reports that they file. Based solely upon our review
of the copies of such forms we have received, and written representations from
certain directors and executive officers that no Form 5s were required to be
filed, we believe that, during 1999, all reports required by Section 16(a) to be
filed by such persons were timely filed, except for one report regarding a stock
option exercise filed late by Mr. Briggs.

EMPLOYMENT AGREEMENTS, CHANGE IN CONTROL ARRANGEMENTS AND OTHER COMPENSATION
ARRANGEMENTS

         In December 1991, we entered into employment agreements, which have
been amended several times, with W. Phillip Marcum, our President, Chief
Executive Officer and Chairman of the Board, and A. Bradley Gabbard, our
Executive Vice President and Chief Financial Officer. These employment
agreements were most recently amended effective January 1, 2000 to provide for
an extension of the employment term until December 31, 2003 for Mr. Marcum and
until December 31, 2001 for Mr. Gabbard, with automatic additional one-year
renewal periods when the term expires, unless either party gives six months
prior written notice of termination. The base salaries under these employment
agreements, which are subject to annual upward adjustments at the discretion of
the Board of Directors, are currently set at $295,000 for Mr. Marcum and
$175,000 for Mr. Gabbard. In addition to the base annual compensation, the
employment agreements provide, among other things, for standard benefits
commensurate with the management levels involved. The employment agreements also
provide for us to establish an incentive compensation fund, to be administered
by our Compensation Committee, to provide for incentive compensation to be paid
to each officer or employee (including Messrs. Marcum and Gabbard) deemed by the
Compensation Committee to have made a substantial contribution to us in the
event of a change of control of Metretek or of the sale of substantially all of
our assets or similar transactions. The total amount of incentive compensation
from the fund available for distribution will be determined by a formula based
on the amount by which the fair market value per share of the Common Stock
exceeds $10.08, multiplied by a factor ranging from 10-20% depending upon the
ratio of the fair market value to $10.08. In the case of the sale of a
significant subsidiary or substantially all of the assets of a significant
subsidiary, a similar pro rata distribution is required. As amended, the
employment agreements with Messrs. Marcum and Gabbard provide that if the
employment period expires without being renewed, then the executive is entitled
to receive a lump-sum severance payment equal to 12 months, for Mr. Marcum, and
six months, for Mr. Gabbard, of his then base salary, and continued
participation in all our insurance plans for such additional period. The
employment agreements also contain certain restrictions on each executive's
ability to compete, use of confidential information and use of inventions and
other intellectual property.

         As amended, the employment agreements with Messrs. Marcum and Gabbard
also include "change in control" provisions designed to provide for continuity
of management in the event we undergo a change in control. The agreements
provide that if within three years after a change in control, the executive is
terminated by us for any reason other than for "cause", or if the executive
terminates his employment for "good reason" (as such terms are defined in the
employment agreements), then the executive is entitled to receive a lump-sum
severance payment equal to two times, for Mr. Marcum, and one times, for Mr.
Gabbard, the amount of his then base salary, together with certain other
payments and benefits, including continued participation in all our insurance
plans for a period of two years for Mr. Marcum and one year for Mr. Gabbard.
Under these employment agreements, a "change in control" will be deemed to have
occurred only if: (1) any person or group becomes the beneficial owner of 50% or
more of our Common Stock; (2) a majority of our present directors are replaced,
unless the election of any new director is approved by a two-thirds vote of the
current (or properly approved successor) directors; (3) we approve a merger,
consolidation, reorganization or combination, other than one in which our voting
securities outstanding immediately prior thereto continue to represent more than
50% of our total voting power or of the surviving corporation following such a
transaction and our directors continue to represent a majority of our directors
or of the surviving corporation following such transaction; or (4) we approve a
sale of all or substantially all of its assets.

(1)      For purposes of this table, the value of unexercised in-the-money
         options is calculated based upon the difference between $4.75, the
         closing sale price of the Common Stock on December 31, 1999 as reported
         on the Nasdaq National Market, and the option exercise price.

DIRECTOR COMPENSATION

         Directors who are also our officers or employees do not receive any
additional compensation for serving on the Board of Directors. All directors are
reimbursed for out-of-pocket costs of attending meetings of the Board of
Directors and its committees. Directors who are not our officers or employees
("Non-Employee Directors") currently receive a fee of $1,000 for attendance at
each meeting of the Board of Directors. Non-Employee Directors also receive
stock options. Until June 1998, these options were granted under our Directors'
Stock Option Plan (the "Directors' Plan"). Since June 1998, these options have
been granted under our 1998 Stock Incentive Plan (the "1998 Plan"). Under the
formula for these stock option grants, each person who is first elected or
appointed to serve as a Non-Employee Director is automatically granted an option
to purchase 5,000 shares of Common Stock. On the date of the Annual Meeting of
Stockholders each year, each Non-Employee Director (who has been such for at
least six months) is automatically granted an option to purchase 2,500 shares of
Common Stock. All options vest and become exercisable immediately upon grant.
Additional non-formula options can be granted to Non-Employee Directors under
the 1998 Plan in the discretion of the Board of Directors.

         Each Non-Employee Director has the right to irrevocably elect on an
annual basis in advance to receive additional stock options under the 1998 Plan
("Meeting Options") in lieu of cash fees for attending meetings of the Board of
Directors. The Meeting Options are granted on the date of each Annual Meeting of
Stockholders and vest in 25% increments on the date of each of the subsequent
four regular quarterly meetings of the Board of Directors attended by such
Non-Employee Director. The number of shares of Common Stock exercisable upon the
exercise of Meeting Options are such that the value of the stock options granted
is equal to the amount of fees waived.

         All options granted to Non-Employee Directors are nonqualified stock
options exercisable at a price equal to the fair market value of the Common
Stock on the date of grant and have ten year terms, subject to earlier
termination in the event of the termination of the optionee's status as a
director or the optionee's death. Options typically remain exercisable for one
year after a Non-Employee Director dies and for that number of years after a
Non-Employee Director leaves the Board of Directors (for any reason other than
death or removal for cause) equal to the number of full or partial years that
the Non-Employee Director served as a director, but not beyond the ten year term
of the option. On October 6, 1998, the exercise price of all options then
outstanding to Non-Employee Directors under the Directors' Plan and under the
1998 Plan was reduced to $2.00 per share, the closing sale price of the Common
Stock as reported on the Nasdaq National Market on such date. As of December 31,
1999, options to purchase 92,500 shares of Common Stock were outstanding to
Non-Employee Directors under the Directors' Plan and options to purchase 34,209
shares of Common Stock were outstanding to Non-Employee Directors under the 1998
Plan, at exercise prices ranging from $1.75 to $2.00 per share.

ITEM 11. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

         The following table sets forth information regarding the beneficial
ownership of our Common Stock as of March 15, 2000 by:

         -        each person who is known by us to beneficially own 5% or more
                  of the outstanding shares of our Common Stock;

         -        each of our directors;

         -        each of the Named Executive Officers; and

<PAGE>   53
         -        all of our directors and executive officers as a group.

         Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission. Unless otherwise indicated below, to our
knowledge, each stockholder named in the table below has sole voting and
investment power with respect to the shares of Common Stock beneficially owned,
subject to applicable community property laws. In computing the number of shares
beneficially owned by a person and the percentage of beneficial ownership of
that person, beneficial ownership includes any shares of Common Stock subject to
options, warrants and other rights that are currently exercisable or exercisable
within 60 days of March 15, 2000. Such shares, however, are not included for
purposes of computing the beneficial ownership of any other person. The
percentage of beneficial ownership is based upon 5,003,678 shares of Common
Stock outstanding on March 15, 2000.

ITEM 12. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         In December 1997, MGT sold one-third of its preferred and performance
share interests and one-third of its interest in future management and
administrative fees in two business trusts to Odessa Exploration Incorporated
("Odessa"), a subsidiary of Key. Odessa paid MGT $700,000 for its interest, a
mutually agreed reduction from an initial purchase price amount of $1,000,000.
W. Phillip Marcum, our Chairman of the Board, President and Chief Executive
Officer, and Kevin P. Collins, are directors of both Metretek and Key, although
Mr. Collins was not a director of Metretek at the time of the transaction.

<PAGE>   56
         On May 4, 1998, in connection with our acquisition, through Metretek
Florida, of certain assets of a subsidiary of American Meter, Metretek Florida
entered into a license agreement with American Meter, for the license by
American Meter and American Meter Software to Metretek of certain operating
software, and the development, manufacture and sale by Metretek Florida to
American Meter of certain electronic components and related equipment pertaining
to electronic temperature and pressure correction to be embedded within certain
new rotary and turbine meters of American Meter. The license agreement also
grants to American Meter and its affiliates the right to sell Metretek Florida
products in the United States and Canada at certain agreed-upon prices.
Subsequent to the acquisition, Metretek Florida and American Meter entered into
an international sales agreement, pursuant to which American Meter and its
affiliates have the non-exclusive right to sell Metretek Florida products
internationally. Harry I. Skilton, the President, Chief Executive Officer and a
director of American Meter, became a member of our Board of Directors in May
1998 in connection with this acquisition. During fiscal 1998 and 1999, we
recorded revenues of approximately $522,000 and $593,000 with respect to sales
to American Meter under the license agreement and the international sales
agreement. The terms of the license agreement and the international sales
agreement were the result of arms-length negotiations between the parties.

         Each material transaction between us and any related party is approved
by a majority of the members of our Board of Directors who are disinterested in
the transaction.

INDEPENDENT AUDITORS' REPORT


To the Board of Directors and Stockholders of
  Metretek Technologies, Inc.:

We have audited the accompanying consolidated balance sheets of Metretek
Technologies, Inc. and subsidiaries (the "Company") as of December 31, 1999 and
1998, and the related consolidated statements of operations, stockholders'
equity, and cash flows for the years then ended. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of Metretek Technologies, Inc. and
subsidiaries at December 31, 1999 and 1998, and the results of their operations
and their cash flows for the years then ended in conformity with accounting
principles generally accepted in the United States of America.

      Company.

      MTEK was incorporated on April 5, 1991. The focus of its continuing
      business operations is in three areas relating to the natural gas
      industry: 1) the design, manufacture and distribution of automated energy
      consumption monitoring and recording systems, 2) natural gas measurement
      services, and 3) Internet based business to business energy information
      and services. Metretek designs, manufactures and sells automated systems
      to monitor and record natural gas consumption of commercial and industrial
      customers of natural gas utility companies. Southern Flow provides natural
      gas measurement services. PowerSpring provides Internet based business to
      business energy information and services. Each area of business operation
      is considered to be a reportable segment - see Note 9.

      In June 1999, the stockholders of the Company formally approved a change
      in name of the Company from Marcum Natural Gas Services, Inc. to Metretek
      Technologies, Inc.

      PRINCIPLES OF CONSOLIDATION - The consolidated financial statements
      include the accounts of MTEK and its subsidiaries after elimination of
      intercompany accounts and transactions.

      REVERSE STOCK SPLIT - On July 6, 1998, the Company effected a 1-for-4
      reverse split of the Company's Common Stock. Accordingly, all historical
      amounts contained in the consolidated financial statements, including
      weighted average share and per share amounts in the consolidated
      statements of operations, as well as common stock and additional paid-in
      capital amounts in the consolidated balance sheets and consolidated
      statements of stockholders' equity, have been adjusted to reflect the
      reverse stock split on a retroactive basis. In addition, all historical
      common stock, common stock option, and common stock warrant amounts in the
      notes to the consolidated financial statements have been adjusted to
      reflect the reverse stock split on a retroactive basis.

      REVENUE RECOGNITION - Equipment and supply sales are recognized when
      delivered, and natural gas measurement revenues are recognized as services
      are provided.

      PROPERTY, PLANT AND EQUIPMENT - Property, plant and equipment is stated at
      cost and is generally depreciated on the straight-line basis over
      estimated useful lives ranging from 2 to 40 years. Property, plant and
      equipment includes items under capital lease with a net book value of $0
      and $1,481 at December 31, 1999 and 1998, respectively.

      INTANGIBLE ASSETS - Southern Flow customer lists are being amortized over
      20 years using the straight-line method. Goodwill and other intangibles
      are being amortized over periods ranging from 10 to 20 years. The Company
      capitalizes software development costs integral to its products once
      technological feasibility of the products and software has been
      determined. Software development costs are being amortized over five
      years, using the straight-line method. Unamortized software development
      costs at December 31, 1999 and 1998 are $283,618 and $420,165,
      respectively. Patents and license agreements are amortized on a
      straight-line basis over the lesser of their estimated economic lives or
      their legal term of existence, generally 10 to 17 years. When events and
      circumstances so indicate, the Company assesses the recoverability of
      goodwill and other intangible assets based on undiscounted cash flows. If
      an impairment is indicated, assets are written down to estimated fair
      value. No impairment losses have been recognized in either of the periods
      presented.

</TABLE>


      USE OF ESTIMATES - The preparation of the Company's consolidated financial
      statements in conformity with generally accepted accounting principles
      requires management to make estimates and assumptions that affect the
      amounts reported in these financial statements and accompanying notes.
      Actual results could differ from those estimates.

      FOREIGN CURRENCY - The assets and liabilities of Metretek Europe are
      translated at the rate of exchange at year end while sales and expenses
      are translated at the average rates in effect during the year. The net
      effect of translation adjustments are shown in the accompanying financial
      statements as a component of other comprehensive income. During 1998, the
      assets and liabilities and foreign currency sales and expenses were not
      significant. Accordingly, there were no translation adjustments in 1998.

      COMPREHENSIVE INCOME (LOSS) - The Company's other comprehensive income
      (loss) consists of foreign currency translation adjustments and is
      presented in the Consolidated Statement of Stockholders' Equity.

      INCOME (LOSS) PER SHARE - The Company's net loss from continuing
      operations, loss from discontinued operations and net loss, per share is
      based on the weighted average shares of common stock outstanding during
      the periods presented. The assumed conversion of stock options and
      warrants is excluded because their effect is antidilutive.

      STOCK BASED COMPENSATION - The Company utilizes the intrinsic value method
      to account for employee stock options as well as stock options issued to
      independent members of the board of directors. The Company utilizes the
      fair value method to account for employee stock based compensation under
      its 1998 Employee Stock Purchase Plan and for stock based compensation to
      non-employees.

      DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES - In June 1998, the
      Financial Accounting Standards Board issued Statement of Financial
      Accounting Standard (SFAS) 133, "Accounting for Derivative Instruments and
      Hedging Activities," which, as amended by SFAS No. 137, is effective for
      all fiscal quarters of fiscal years beginning after June 15, 2000. SFAS
      133 requires that all derivatives be recognized at fair value in the
      statement of financial position, and that the corresponding gains or
      losses be reported either in the statement of operations or as a component
      of comprehensive income, depending on the type of hedging relationship
      that exists. The Company is currently evaluating the impact SFAS 133 will
      have on its financial statements, if any.

      COSTS OF COMPUTER SOFTWARE DEVELOPED OR OBTAINED FOR INTERNAL USE - In
      March 1998, the Accounting Standards Executive Committee issued Statement
      of Position (SOP) No. 98-1, "Accounting for the Costs of Computer Software
      Developed or Obtained for Internal Use," which the Company adopted January
      1, 1999. The adoption of SOP No. 98-1 did not have a material effect on
      the financial position or results of operations of the Company.

      RECLASSIFICATION - Certain 1998 amounts have been reclassified to conform
      to current year presentation.

2.    NEW BUSINESS VENTURE

      On September 13, 1999, the Company entered into a strategic relationship
      with Scient Corporation ("Scient") to assist the Company in designing and
      creating an Internet-based business to enable the Company to take its
      measurement information products, services, and data measurement
      technologies to the market of end-users of natural gas and electricity
      (the "Internet Project"). The Internet Project is being developed and will
      be operated through PowerSpring. Simultaneously, the Company entered into
      a joint venture agreement with Mercator Energy Incorporated ("Mercator")
      whereby Mercator provided consulting services (the "Mercator Consulting
      Agreement") to TotalPlan. TotalPlan was organized to develop and market
      the Company's proprietary turnkey data collection and software management
      system that enables commercial users of natural gas and electricity to
      monitor and better manage their energy purchases and consumption, which is
      designed to capitalize on a continuing trend toward deregulation within
      the industry.

      In order to finance the initial phase of its Internet Project, the
      Company, together with Metretek and Southern Flow, entered into an
      amendment (the "Loan Amendment") to the terms of its $5,000,000 credit
      facility with its commercial lender. The Loan Amendment amends certain
      covenants of the loan agreement, including the Company's minimum annual
      net income (or maximum annual net loss in 1999), minimum tangible net
      worth and minimum debt service coverage ratio.

      The Company anticipates that the costs of launching the Internet Project,
      which involves several phases, will require estimated expenditures of
      between approximately $6,000,000 and $8,000,000. The Company has the right
      to terminate the Internet Project on 30 days notice, with maximum
      additional expenditures of $100,000.

      In connection with the Internet Project, the Company issued to Scient a
      warrant (the "Scient Warrant") to purchase 125,000 shares of common stock
      of the Company. The Scient Warrant becomes exercisable in September 2000,
      at exercise prices split between $5.00 and $10.00 per share, and expires
      in September 2002. Scient has registration rights with respect to the
      common stock issuable upon the exercise of the Scient Warrant.

      Pursuant to the Mercator Consulting Agreement, Mercator provided
      broker-agent natural gas consulting services to TotalPlan for a fee of
      $7,500 per month. The term of the Mercator Consulting Agreement was six
      months, renewable by mutual consent for six additional months. In
      connection with the Mercator Consulting Agreement, the Company issued to
      Mercator an option to purchase up to 25% of the capital stock of TotalPlan
      for a purchase price equal to 25% of TotalPlan's cumulative net loss,
      which was exercisable only during the term of the Consulting Agreement.
      The Company also issued to Mercator a warrant (the "Mercator Warrant") to
      purchase 60,000 shares of common stock of the Company. The Mercator
      Warrant vests in three tranches from the date of issuance through March
      2000, with exercise prices ranging between $4.50 and $5.50 per share, and
      expires in September 2002. Mercator has registration rights with respect
      to the common stock issuable upon the


                                     F - 11
<PAGE>   72
      exercise of the Mercator Warrant. As discussed further in Note 10, the
      Company subsequently acquired Mercator and merged the operations of
      Mercator and TotalPlan into PowerSpring.

      In connection with the Loan Amendment, the Company paid customary fees to
      the commercial lender and issued a warrant (the "Lender Warrant") to
      purchase 20,000 shares of common stock of the Company. The Lender Warrant
      is exercisable for three years at an exercise price of $5.00 per share.
      The commercial lender has registration rights with respect to the common
      stock issuable upon the exercise of the Lender Warrant.

      Compensation expense for the fair value of the Scient, Mercator and Lender
      Warrants is being recognized over the period in which the services are
      being performed or the remaining term of the Loan Agreement. Compensation
      expense associated with the warrants in the amount of $70,029 has been
      recognized in the consolidated statement of operations during the year
      ended December 31, 1999.

3.    ACQUISITIONS

      On May 4, 1998, the Company, through its wholly owned subsidiary,
      Metretek, purchased substantially all of the assets and business of
      American Meter Software Corporation (formerly known as Eagle Research
      Corporation) ("American Meter Software"), pertaining to electronic
      correctors and non-radio-frequency meter reading devices for the natural
      gas and electric utility industry. American Meter Software was a wholly
      owned subsidiary of American Meter Company ("American Meter"), which is
      ultimately controlled by Ruhrgas AG, a German corporation. American Meter
      Software subsequently merged into American Meter. The assets acquired by
      Metretek include certain inventory, equipment, trademarks and technology
      of American Meter Software and American Meter used in the design,
      manufacture and sales of electronic measurement process control and
      telemetry systems to utility companies in the natural gas and petroleum
      industries. In connection with the acquisition, Metretek assumed certain
      transitional employee costs and product warranty obligations of American
      Meter Software. The assets and business operations acquired have been
      relocated to Metretek's existing facility in Melbourne, Florida.

      In consideration for the purchase of the assets and business, the Company
      and Metretek paid and delivered to American Meter Software at the closing
      an aggregate purchase price consisting of $1,300,000 in cash, 439,560
      unregistered shares of Common Stock of the Company valued at their fair
      value of $2,000,000, and a $600,000 convertible subordinated promissory
      note (the "American Meter Note"). Subsequent to closing, the purchase
      price was adjusted down by $85,000 to reflect a decrease in American Meter
      Software's inventory between December 31, 1997 and May 4, 1998, partially
      offset by transitional costs assumed by Metretek.

      The American Meter Note was convertible at any time at the option of
      American Meter Software, into 105,495 shares of Common Stock of the
      Company at the rate of approximately $5.69 of principal per share, which
      conversion option was exercised by American Meter on March 16, 2000. Prior
      to its conversion, the American Meter Note bore interest on the unpaid
      principal balance at a fixed rate equal to 7.5% per annum and was due and
      payable May 4, 2002. The Company granted to American Meter Software the
      one-time option to cause the shares of Common Stock issued at the closing
      and issuable upon the conversion of the American Meter Note to be
      registered under the Securities Act of 1993, as amended, and applicable
      state securities laws, and has also granted American Meter Software
      certain piggy-back registration rights to include such shares in any
      registration statement filed by the Company, subject to customary
      underwriter cutbacks.


                                     F - 12
<PAGE>   73
      Metretek also entered into a license agreement ("License Agreement") with
      American Meter and American Meter Software, providing for the license by
      American Meter and American Meter Software to Metretek of certain
      operating software, and the development, manufacture and sale by Metretek
      to American Meter and American Meter Software of certain electronic
      components and related equipment pertaining to electronic temperature and
      pressure correction to be imbedded with certain new rotary and turbine
      meters of American Meter. The License Agreement also grants American Meter
      and its affiliates the right to sell Metretek products in the United
      States and Canada at certain agreed-upon prices. American Meter and
      American Meter Software also entered into a Non-Competition Agreement with
      the Company and Metretek, pursuant to which American Meter and American
      Meter Software have agreed not to compete with Metretek in the acquired
      business for five years from the closing date.

      The acquisition was accounted for as a purchase, and therefore the results
      of operations of the American Meter Software business acquired have been
      combined with those of the Company effective May 4, 1998.

      On June 15, 1998, Metretek, through its wholly owned subsidiary, Sigma VI,
      acquired substantially all of the assets of Quality Contract
      Manufacturing, Inc. ("QCMI") in exchange for $150,000 in cash. QCMI is a
      contract manufacturer of electronic circuit boards, sub-assemblies, and
      cable assemblies serving customers primarily in Melbourne, Florida and the
      immediately surrounding area. The acquisition was accounted for as a
      purchase and therefore the results of operations of QCMI have been
      combined with those of the Company effective June 15, 1998.

      The purchase prices of the foregoing acquisitions (including transaction
      costs) were allocated as follows:

4.    DISCONTINUED OPERATIONS

      During 1998, the Company decided to discontinue the operations of MGT, a
      directly owned subsidiary of the Company that was formed to acquire or
      finance the acquisition of natural gas assets through privately financed
      programs, and then to manage and maintain a small ownership interest in
      those programs. This decision was based on the declining prospects of the
      markets and in order to enable the Company to focus on its other
      operations. In December 1997, MGT sold one-third of its interests in two
      of the three programs it then managed, and in March 1998, MGT liquidated
      the third program. MGT does not intend to form or manage any new programs,
      although it will continue to manage the remaining two programs that
      operate natural gas related assets until MGT's interest in these programs
      are sold.

      On April 14, 1998, the Company and its wholly owned subsidiaries, Southern
      Flow and Metretek, entered into a loan and security agreement (the "Loan
      Agreement") with a commercial bank (the "Lender") providing for a combined
      $5,000,000 credit facility consisting of loans (the "Loans") and letters
      of credit to Southern Flow and Metretek, subject to limitations described
      below. The Loan Agreement provides for daily advances to Southern Flow and
      Metretek in the form of Loans to fund capital requirements, and daily
      paydowns on outstanding balances of the Loans from collection of customer
      accounts receivable. The Company makes monthly interest payments computed
      at prime plus 1% (9.5% at December 31, 1999) on outstanding balances of
      the Loans. The Loans mature on March 14, 2001. The Loans are secured by
      the tangible and intangible assets of the Company, Southern Flow, and
      Metretek, including equipment, inventories, receivables, and cash
      deposits, and the pledge of the shares of the Company's subsidiaries. The
      Loan Agreement requires the Company to maintain a minimum tangible net
      worth, a maximum debt to tangible net worth ratio, minimum annual net
      income (maximum loss), a minimum debt service coverage ratio, and contains
      other standard covenants related to operations of the Company, including
      prohibitions on the payment of dividends and the issuance or repurchase of
      securities (with certain exceptions) without the Lender's consent.

      Loans are limited to the sum of 80% of eligible accounts receivable of
      Southern Flow and Metretek and 50% of raw materials and finished goods
      inventories (up to a combined maximum of $1,500,000) of Southern Flow and
      Metretek.

      At December 31, 1999, the Company had a combined $3,587,864 Loan
      availability, of which $269,968 had been borrowed by Southern Flow and
      Metretek, leaving $3,317,896 in unused Loan availability. Proceeds from
      initial advances under the Loan Agreement were used to extinguish the
      Company's existing loans, lines of credit, and accrued interest with two
      commercial bank lenders in the aggregate amount of $468,993, including
      $279,021 of a term loan and accrued interest owed by the Company's
      discontinued MGT segment to a commercial bank lender.

      The balance of the term loan at December 31, 1999 and 1998 consists of the
      7.5% American Meter convertible note incurred in connection with the
      acquisition discussed in Note 3.

6.    COMMITMENTS AND CONTINGENCIES

      LEGAL PROCEEDINGS - In 1993, a former employee filed an action in Denver
      District Court against DVCO Fuel Systems, Inc. ("DVCO"), a former
      subsidiary of Marcum Denver, and the Company, alleging that the Company
      conspired with certain third parties to defraud him and that the Company
      intentionally interfered with certain contracts in which he had an
      interest. The former employee is seeking damages in the amount of
      approximately $420,000 and punitive damages. The Company has denied the
      former employee's claims and has asserted counterclaims against the former
      employee, alleging that (i) he breached an agreement with the Company
      which included a legal release, (ii) he made intentional and/or negligent
      misrepresentations regarding his qualification and reputation in the
      compressed natural gas industry, (iii) he breached his fiduciary duty to
      the Company, and (iv) he disparaged the Company. On September 18, 1997,
      the former employee's action was dismissed as a result of the Court's
      grant of the motion by the Company and DVCO for summary judgment against
      the former employee's claims. On February 18, 1999, the Colorado Court of
      Appeals reversed the summary judgment decision and remanded the case for
      trial as to the conspiracy claim only. The action is currently scheduled
      for trial in the third quarter of 2000. The Company believes the
      allegations against it and DVCO are without merit and intends to defend
      the action vigorously. Although the outcome of this litigation is not
      determinable with certainty, in the opinion of the Company's management,
      this litigation is not expected to have a material adverse effect on the
      business, financial condition or results of operations of the Company

      Other than as set forth above, there are no legal proceedings pending or,
      to the knowledge of the Company, threatened against the Company or any of
      its assets, other than litigation incidental and not material to its
      business.

      OPERATING LEASES - The Company leases business facilities and vehicles
      under operating lease agreements which specify minimum rentals.
      Substantially all leases have renewal provisions. Rental expense for the
      years ended December 31, 1999 and 1998 totaled $1,155,305 and $1,119,290,
      respectively.

      EMPLOYEE BENEFIT PLANS - The Company has a defined contribution savings
      and investment plan (the "401(k) Plan") under Section 401(k) of the
      Internal Revenue Code. All employees age 21 or older with at least one
      year of service are eligible to participate in the 401(k) Plan. The 401(k)
      Plan provides for discretionary contributions by employees of up to 15% of
      their eligible compensation. The Company may make discretionary matching
      contributions up to 50% of participant contributions, subject to a maximum
      of 6% of each participant's eligible compensation. The Company's 401(k)
      Plan expense for the years ended December 31, 1999 and 1998 was $148,934
      and $146,161, respectively.

      LICENSE AGREEMENT - Metretek has a commitment to pay in cash or restricted
      shares of common stock of the Company a 5% royalty on sales of certain
      royalty-bearing products of Metretek with a minimum annual royalty of
      $50,000 through the year 2002. In September 1998, the Company repurchased
      18,181 shares of its common stock that had been issued to the licensor in
      prior years in order to satisfy certain obligations of Metretek under the
      license agreement. Royalty expense of $50,000 has been recognized in both
      1999 and 1998 under the license agreement.

7.    INCOME TAXES

      No tax expense or benefit has been recognized during the years ended
      December 31, 1999 and 1998 because of net operating losses incurred and
      because a valuation allowance has been provided for 100% of the net
      deferred tax assets at December 31, 1999 and 1998.

      At December 31, 1999, the Company had unused net operating losses to carry
      forward against future years' taxable income of approximately $23,276,000
      expiring in various amounts from 2000 to 2014. At December 31, 1999, the
      Company had unused investment tax credits, general business tax credits,
      and research and development tax credit carryforwards aggregating
      approximately $128,000 expiring in various amounts from 2000 to 2008.

      As a result of its acquisition of Metretek in 1994, the Company acquired a
      remaining net operating loss carryforwards for tax purposes of $3,428,000
      expiring between 2000 and 2002. As a result of the change in ownership
      upon acquisition, utilization of the carryforwards is limited to
      approximately $762,000 annually under Section 382 of the Internal Revenue
      Code.

      As a result of an acquisition in 1991, the Company acquired a remaining
      net operating loss carryforwards for tax purposes of approximately
      $873,000 ($231,000, net of current limitation). Such carryforwards expire
      in 2000 through 2005. As a result of the change in ownership upon
      acquisition, utilization of these net operating loss carryforwards is
      limited to approximately $33,000 annually. If the benefits related to the
      net operating loss carryforwards that were not recognized at the
      acquisition date are recognized in a subsequent period, they will first
      reduce to zero any goodwill related to the acquisition, then reduce to
      zero all other noncurrent intangible assets, and then reduce income tax
      expense.

8.    CAPITAL STOCK

      WARRANT DIVIDEND - On September 18, 1998, the Company distributed 886,442
      common stock Purchase Warrants (the "Warrants") as a dividend to
      stockholders of the Company on the basis of one Warrant for each four
      shares of common stock outstanding on September 10, 1998, the record date
      for the Warrant dividend. Each Warrant is exercisable, for a five-year
      period, for one share of common stock at an exercise price of $4.00. The
      Warrants are subject to redemption by the Company, at $.01 per Warrant,
      in the event the Common Stock trades at or above $6.50 per share for 20
      consecutive trading days. The registration statement and prospectus
      covering the common stock issuable upon exercise of the Warrants also
      covers the resale of up to 155,081 Warrants by a selling security holder.


                                     F - 17
<PAGE>   78
      No accounting recognition was given to warrant dividend. A total of 412
      Warrants have been exercised through December 31, 1999.

      STOCK COMPENSATION - In January 1998, the Company adopted a non-qualified,
      compensatory Employee Stock Purchase Plan (the "1998 Stock Purchase
      Plan"), which allowed eligible employees to purchase shares of the
      Company's Common Stock through payroll deductions. Under the 1998 Stock
      Purchase Plan, employees purchased shares at a price equal to 100% of the
      lower of the beginning or ending fair market value of the shares during
      each one-month offering period. The Company matched the employees'
      purchase on a share-for-share basis. The maximum payroll deduction was 15%
      of an employee's eligible compensation. The Company reserved and
      registered a total of 50,000 shares of Common Stock for offer and issuance
      under the 1998 Stock Purchase Plan. The Company issued 47,244 shares under
      the 1998 Stock Purchase Plan, which has been discontinued. Stock
      compensation expense in the amount of $88,629 was recognized during the
      year ended December 31, 1998 representing the market value of the shares
      of common stock matched by the Company under the 1998 Stock Purchase Plan.

      STOCK INCENTIVE PLAN - In March 1998, the Board of Directors of the
      Company adopted the Metretek Technologies, Inc. 1998 Stock Incentive Plan
      (the "1998 Stock Incentive Plan"), which was approved by the Company's
      stockholders at the Annual Meeting of Stockholders held on June 12, 1998.
      The 1998 Stock Incentive Plan authorizes the Board of Directors to grant
      non-qualified stock options, incentive stock options, stock appreciation
      rights, restricted stock, performance awards and other stock-based awards
      to officers, directors, employees, consultants and advisors of the Company
      and its subsidiaries for up to 250,000 shares of the Company's common
      stock. The 1998 Stock Incentive Plan replaced the Company's existing 1991
      Stock Option Plan and the Company's Directors' Stock Option Plan (the
      "Prior Plans"), and no new awards will be made under the Prior Plans,
      although options outstanding under the Company's Prior Plans were not
      affected by the adoption of the 1998 Stock Incentive Plan. On February 3,
      2000, the stockholders of the Company, at a special meeting, adopted a
      proposal by the Board of Directors to increase the number of shares
      available under the 1998 Stock Incentive Plan to a total of 750,000 shares
      of common stock of the Company.

      STOCK REPURCHASE PLAN - In September 1998, the Board of Directors of the
      Company adopted a stock repurchase plan (the "Stock Repurchase Plan")
      pursuant to which the Company was authorized to purchase up to
      approximately 7% of its outstanding common stock in open market
      transactions, from time to time as management deems appropriate, based on
      the market price of the Company's stock. The Stock Repurchase Plan was
      discontinued on September 20, 1999. Under the Stock Repurchase Plan during
      1998 and 1999, the Company repurchased 96,116 shares of its common stock
      at an average price of $2.22 per share. The repurchased shares have been
      retired.

      STOCK OPTIONS - In December 1991, the Company adopted the 1991 Stock
      Option Plan which was amended and restated on June 4, 1996 ("1991 SOP")
      and the Director's Stock Option Plan ("Director SOP"). Under the 1991 SOP,
      incentive stock options and nonqualified stock options may be granted to
      officers and employees for up to 350,000 shares of common stock. Under the
      1991 SOP, options granted must be at exercise prices not less than the
      fair market value of the Company's common stock on the date of grant. The
      1991 SOP options have a term of ten years with the vesting terms
      determined on the date of the grant. The Director SOP permits the granting
      of nonqualified stock options for up to 162,500 shares of common stock to
      nonemployee directors of the Company. Each Director SOP option is
      exercisable at a price not less than the fair market value of the
      Company's common stock on the date of grant. The Director SOP options have
      a term of ten years and are vested on the date of grant.

      Options granted to certain officers and non-employee directors contain
      limited rights for receipt of cash for appreciation in stock value in the
      event of certain changes in control.

      On October 6, 1998, the Board of Directors approved the repricing of all
      outstanding stock options held by officers, directors and employees of the
      Company to an exercise price of $2.00 per share, the last sale price of
      the common stock as reported on the Nasdaq National Market on such date.
      No repriced officer or employee options (whether or not vested) were
      exercisable prior to October 6, 1999. The other terms of the outstanding
      stock options generally remained unchanged. The repriced options are
      reflected as forfeitures and new grants during the year ended December 31,
      1998 in the summary above.


                                     F - 19

      The weighted average grant date fair values of options granted (including
      repriced options in 1998), during the years ended December 31, 1999 and
      1998 were $1.60 and $.77 per option, respectively. During the year ended
      December 31, 1999, 141,000 of the grants were incentive stock options
      granted to employees and 27,732 of the grants were nonqualified stock
      options granted to nonemployee directors of the Company. During the year
      ended December 31, 1998, 325,059 of the grants (including repriced
      options) were incentive stock options granted to employees and 149,856 of
      the grants (including repriced options) were nonqualified stock options
      granted to nonemployee directors of the Company. The range of exercise
      price for options outstanding as of December 31, 1999 was $1.75 to $5.63.
      The weighted average remaining contractual life of all options outstanding
      at December 31, 1999 was approximately 6.9 years. If the fair value based
      method of accounting for stock options had been applied, the Company's net
      loss and net loss per share would have increased to the pro forma amounts
      indicated below:

      The fair values of stock options were calculated using the Black-Scholes
      stock option valuation model with the following weighted average
      assumptions for grants in 1999 and 1998: stock price volatility at 43% and
      40%, respectively; risk-free rate of return of 5.6% and 5%, respectively;
      dividend rate of $0.00 per year; and an expected term of 4 years for
      options granted to employees and 10 years for options granted to
      directors.

      STOCKHOLDER RIGHTS PLAN - On December 12, 1991, the stockholders of the
      Company approved the Stockholder Rights Plan ("Plan"). The Plan calls for
      the issuance of one preferred share purchase right ("Right") for each
      share of Common Stock held by stockholders of record on December 2, 1991.
      Each Right represents the right to purchase four one-hundredths of a share
      of Series C Preferred Stock of the Company at an initial exercise price of
      $25 per share. The Rights are exercisable through December 1, 2001, unless
      earlier redeemed by the Company. In the event that any person or group
      (with certain exceptions) acquires 15% or more of the Company's
      outstanding Common Stock, the Rights provide for the holder to acquire
      Common Stock of the Company, or acquiring company, at a 50% discount. The
      rights are redeemable by the Company at $.04 per Right.

      STOCK WARRANTS - On March 13, 1998, the Company issued 50,000 stock
      purchase warrants to a consultant for financial advisory services. At
      December 31, 1999, 12,500 of the warrants were vested and exercisable at
      $4.43 per share. The remaining 37,500 stock purchase warrants expired in
      1999 without vesting.

      METRETEK STOCK WARRANTS - Metretek stock warrants were issued by Metretek
      in prior periods in connection with issues of common stock and debentures.
      Stock warrants were also issued by Metretek to certain stockholders as
      remuneration for loans provided to Metretek and to a venture capital
      company as remuneration for services rendered in connection with a new
      issue of special preference stock. At December 31, 1998, stock warrants
      outstanding allow the holders to purchase a total of 36,620 shares of
      Common Stock at prices ranging from $44.48 to $88.96 per share. The
      Metretek stock warrants are exercisable over periods expiring at various
      dates through 2004. No accounting recognition was given


                                     F - 20
<PAGE>   81
      to the Metretek stock warrants, all of which were granted prior to
      guidance set forth in Emerging Issues Task Force Issue No. 96-13,
      "Accounting for Derivative Financial Instruments Indexed to, and
      Potentially Settled in, a Company's Own Stock."

      The shares of the Company's Common Stock issuable upon the exercise of the
      Metretek Warrants cannot be resold unless such resale is registered under
      the Securities Act and under applicable state securities laws or is made
      pursuant to an available exemption therefrom. The holders of the Metretek
      Warrants have the right, under certain circumstances, to require the
      Company to register the shares of the Company's Common Stock issuable upon
      exercise of the Metretek Warrants under the Securities Act and applicable
      state securities laws.

9.    SEGMENT AND RELATED INFORMATION

      The Company's reportable segments are strategic business units that offer
      different products and services. They are managed separately because each
      business requires different technology and marketing strategies.

      The Company has three reportable business segments: automated energy data
      management; natural gas measurement services; and Internet-based energy
      information and services. The operations of the Company's automated energy
      data management segment are conducted by Metretek. Metretek's manufactured
      products fall into three categories: remote data collection products;
      electronic corrector products; and application-specific products. Metretek
      also provides energy data collection and management services and post-sale
      support services for its manufactured products. Historically, Metretek's
      products and services have been provided principally to natural gas local
      distribution companies ("LDCs"). Typically LDCs install Metretek products
      in conjunction with custody transfer meters on their larger customers for
      the purpose of meeting deregulation requirements.

      The operations of the Company's natural gas measurement services segment
      are conducted by Southern Flow. Southern Flow's services include on-site
      field services, chart processing and analysis, laboratory analysis, and
      data management and reporting. These services are provided principally to
      customers involved in natural gas production, gathering, transportation
      and processing.

      The operations of the Company's Internet-based energy information and
      services segment are conducted by PowerSpring. PowerSpring has incurred
      operating costs to date and does not expect to commence revenue generating
      operations until the second quarter of 2000.

      The accounting policies of the reportable segments are the same as those
      described in Note 1 of the Notes to Consolidated Financial Statements. The
      Company evaluates the performance of its operating segments based on
      income (loss) before income taxes, nonrecurring items and interest income
      and expense. Intersegment sales are not significant.

      Summarized financial information concerning the Company's reportable
      segments is shown in the following table. The "Other" column includes
      corporate related items, results of insignificant operations and, as it

10.   SUBSEQUENT EVENTS

      On February 4, 2000, the Company completed a $14,000,000 private placement
      (the "Units Private Placement") of 7,000 ("Units"), including 1,450 Units
      the Company issued on December 9, 1999. Each Unit consisted of 200 shares
      of common stock, 1 share of Series B Preferred Stock and warrants ("Unit
      Warrants") to purchase 100 shares of common stock. In the Units Private
      Placement, the Company issued 1,400,000 shares of common stock, 7,000
      shares of Series B Preferred Stock and Unit Warrants to purchase 700,000
      shares of common stock. The Units Private Placement was approved and
      ratified by the stockholders of the Company at a special meeting held on
      February 3, 2000.

      Each share of Series B Preferred Stock is mandatorily redeemable on
      December 9, 2004 at a liquidation preference of $1,000 per share plus
      accrued and unpaid dividends, accrues dividends at 8% annually payable
      quarterly in arrears, and is convertible at any time after June 9, 2000 at
      the option of the holder into 168.5374 shares of common stock of the
      Company. In addition, the Company has the right to redeem the Series B
      Preferred Stock on or after December 9, 2000, if the Company's common
      stock is trading at 200% of the conversion price of the Series B Preferred
      Stock. The conversion rate of the


                                     F - 22
<PAGE>   83
      Series B Preferred Stock may be subject to downward adjustment on December
      9, 2000 if the average closing bid price of the Company's common stock for
      the 30 trading days immediately preceding that date is less than the
      conversion price then in effect, provided that the conversion price cannot
      be reduced by more than 50%. The Series B Preferred Stock is also subject
      to certain anti-dilution provisions.

      Each Unit Warrant entitles the holder to purchase one share of the
      Company's common stock at an initial exercise price of $6.7425 per share.
      The initial exercise price of the Unit Warrants may also be subject to
      downward adjustment on December 9, 2000 if the average closing bid price
      of the Company's common stock for the 30 trading days immediately
      preceding that date is less than the exercise price of the Unit Warrants
      then in effect.

      The proceeds from the sale of the Units, including the 1,450 Units issued
      on December 9, 1999, have been allocated to common stock, the Unit
      Warrants, and the Series B Preferred Stock based on the relative fair
      value of each on the date of issuance. This allocation process resulted in
      the Series B Preferred Stock issued on February 4, 2000 being initially
      recorded at a discount of $141 per share from its $1,000 per share
      liquidation value. This discount will be recorded as a distribution over
      the term of the Series B Preferred Stock. Another discount resulted from
      the increase in the fair market value of a share of the Company's common
      stock from the date the Company offered to sell 5,550 Units to February 4,
      2000, the date the Units were issued. This increase caused the conversion
      feature of the Series B Preferred Stock to be "in the money" on February
      4, 2000. The discount of $859 per share related to the "in the money"
      conversion feature will also be recorded as a distribution between
      February 4 and June 9, 2000, the date the Series B Preferred Stock can
      first be converted into common stock of the Company.

      The primary purpose of the Units Private Placement was to raise capital to
      enable the Company to develop the Internet-based business of PowerSpring.
      A portion of the proceeds was also used to repay outstanding indebtedness,
      and the remaining proceeds will be used for general corporate and working
      capital purposes, including potentially providing the funds to finance an
      acquisition opportunity, if one were to arise.

      On March 17, 2000, the Company acquired Mercator Energy Incorporated
      ("Mercator") through a merger with a wholly-owned subsidiary of
      PowerSpring. Mercator is a Denver-based natural gas services and brokerage
      company that acts as an independent broker-agent for both producers and
      users. This acquisition will provide PowerSpring with Mercator's expertise
      in the area of energy procurement, which is an important element in the
      Company's Internet business strategy.

      In consideration for the acquisition of Mercator, the Company delivered to
      the sole shareholder of Mercator prior to the acquisition, $408,334 in
      cash, a $741,666 non-negotiable promissory note payable by PowerSpring
      over two years and secured by a general security interest in the assets of
      PowerSpring, and 2,500,000 shares of common stock of PowerSpring.
      Subsequent to the acquisition of Mercator, the Company owns 87.5% of the
      outstanding shares of PowerSpring common stock, and Mercator has become a
      wholly-owned subsidiary of PowerSpring. PowerSpring and Metretek entered
      into a stockholder's agreement with the former owner of Mercator that
      addresses certain rights related to PowerSpring common stock, including a
      right for the former owner of Mercator to put his shares of PowerSpring
      common stock back to PowerSpring at an appraised value over three years if
      PowerSpring has not completed an initial public offering or has not sold
      its business within two years.

      PowerSpring also entered into a two-year employment agreement with the
      former owner of Mercator which included an option to purchase 60,000
      shares of common stock of the Company exercisable, at


                                     F - 23
<PAGE>   84
      $17.88 per share, and an option to purchase 200,000 shares of PowerSpring
      common stock, exercisable at $.30 per share.

      In September 1999, the Company had entered into a consulting and joint
      venture agreement with Mercator, under which Mercator provided energy
      procurement consulting services to the Company. In connection with the
      acquisition of Mercator, the consulting and joint venture agreement and a
      related stock option agreement were terminated.

         expenses incurred in connection with this Agreement and the
         consummation of the transactions contemplated hereby.

                  (o) Construction. In the event an ambiguity or question or
         intent or interpretation arises, this Agreement shall be construed as
         if drafted jointly by the parties hereto and no presumption or burden
         of proof shall arise favoring or disfavoring any party hereto by virtue
         of the authorship of any of the provisions of this Agreement.

                  (p) Specific Performance. Each of the parties hereto
         acknowledges and agrees that the other parties hereto would suffer
         irreparable damage for which an adequate remedy at law would not be
         available in the event any of the provisions of this Agreement is not
         performed in accordance with its specific terms or otherwise is
         breached. Accordingly, each of the parties hereto agrees that the
         non-breaching parties shall be entitled to an injunction,

         competent jurisdiction to prevent breaches of, and to specifically
         enforce, the provisions of this Agreement.

                  (q) Publicity. No party hereto shall, directly or through its
         affiliates, make any public statement, announcement, press release or
         other disclosure regarding this Agreement, the other party or its
         relationship under this Agreement or with the other party without the
         prior consent of the other party (which consent shall not be
         unreasonably withheld or delayed), except (i) to the extent such
         disclosure is required by law, judicial process or rule, regulation or
         requirement of the Nasdaq Stock Market, or (ii) to the Bank.

                  (r) Interpretation of Certain Provisions. Except as otherwise
         expressly provided herein, as used in this Agreement:

                           (i) Any reference to any federal, state, local or
                  foreign statute or law shall be deemed also to include a
                  reference to all rules and regulations promulgated thereunder.

                           (ii) The term "including" means "including, without
                  limitation".

                           (iii) The term "Person" means and includes an
                  individual, corporation, partnership, limited liability
                  company, joint venture, trust, association, unincorporated
                  organization, governmental or regulating body or authority, or

                  and the terms "Person" and "Persons" and the like shall be
                  construed to mean such number and gender as the context, the
                  circumstances or its antecedent may require.

                           (v) The terms "hereof", "herein", "hereunder" and
                  words of similar import refer to this Agreement as a whole,
                  and not to any Section, subsection or clause of this
                  Agreement.

                    REPRESENTATIONS AND WARRANTIES OF SELLER

         In order to induce Purchaser and Merger Sub to enter into this
Agreement and to perform their obligations hereunder, Seller hereby represents
and warrants to and for the benefit of Purchaser and Merger Sub as follows:

         SECTION 2.1. ORGANIZATION. The Company is a corporation duly organized,
validly existing and in good standing under the laws of the State of Colorado.
The Company is duly qualified to do business and is in good standing as a
foreign corporation in each jurisdiction listed in Schedule 2.1 hereto, which is
each jurisdiction in which either the conduct of its business or activities or
the ownership, lease or operation of its properties or assets requires such
qualification. Except for the jurisdictions in which the Company is incorporated
or is qualified as a foreign corporation, (i) no other jurisdiction has claimed,
in writing or otherwise, that the Company is required to be licensed or
qualified as a foreign corporation therein, (ii) the Company has never filed
franchise, income or other tax returns in any other jurisdiction, and (iii) the
Company does not own, lease or operate any property in any other jurisdiction.

         SECTION 2.2. SUBSIDIARIES. The Company has no direct or indirect
subsidiaries and does not own, hold or control, directly or indirectly, any
shares of capital stock or any other equity, voting, ownership or management
interest in any Entity.

         SECTION 2.3. CAPITALIZATION. The authorized capital stock of the
Company consists solely of 40,000 shares of Company Common Stock, no par value,
of which 10,000 shares are issued and outstanding and owned by Seller. The
Company never issued any shares of Company Common Stock or of any other class of
capital stock to any Person other than Seller. No shares of Company Common Stock
are reserved for issuance upon the exercise of outstanding options, warrants or
other rights. The Company has no other equity or voting securities of any class
or series authorized, issued, reserved for issuance or outstanding, and has no
outstanding securities, bonds, debentures, notes or other rights, instruments or

         SECTION 2.16. TAXES.

                  (a) Within the times (or if later all penalties and interest
         related thereto having been paid in full) and in the manner prescribed,
         the Company has accurately prepared in good faith and properly filed
         all federal, state, local and foreign tax returns, reports and forms
         required by law, rule, regulation or otherwise to be filed and has paid
         all taxes, assessments and penalties due and payable, and Seller has
         furnished to Purchaser true and complete copies of all such tax
         returns, reports and forms so filed since January 1, 1996. All tax
         returns, reports and forms filed by the Company accurately set forth
         all items (to the extent required to be included or reflected in such
         returns) relevant to their future tax liabilities, including the tax
         bases of their assets and properties. The Company has fully paid or has
         made adequate provision in the Latest Balance Sheet for all federal,
         state, local and foreign taxes for the period ending on the date of the
         Latest Balance Sheet. The Company has timely collected, withheld and
         paid over all taxes required to be withheld by any federal, state,
         local or foreign taxing authority and complied with all information
         reporting requirements related thereto.

                  (b) There are no disputes pending or overtly threatened by any
         taxing authority as to taxes of any nature payable by the Company. No
         examinations or audits of the federal, state, local or foreign tax
         returns of the Company are currently in progress or, to the best
         knowledge of Seller, threatened or proposed. No deficiency or
         adjustment for any tax has been claimed, proposed or assessed against
         the Company by any taxing authority. The Company has not waived or
         extended any applicable statute of limitations relating to the
         assessment of federal, state, local or foreign taxes. The Company is
         not a party to any tax indemnity, tax sharing, or tax allocation
         agreement. There are no tax liens upon any property or assets of the
         Company except for taxes not yet due and payable.

                  (c) The Company has not filed any consent agreement under
         Section 341(f) of the Code or agreed to have Section 341(f) of the
         Internal Revenue Code of 1986, as amended (the "Code"), apply to any
         disposition of subsection (f) assets (as such term is defined in
         Section 341(f)(4) of the Code) owned by the Company. The acquisition of
         the Company by Purchaser will not result in the payment of any "excess
         parachute payment" within the meaning of Section 280G of the Code, and
         the Company is not a party to any agreement, plan or arrangement that
         could give rise to any payment that would not be deductible pursuant to
         Section 280G or Section 162 of the Code. No outstanding debt
         obligations of the Company are "corporate acquisition indebtedness"
         within the meaning of Section 279(b) of the Code. The Company is not a
         "United States real property holding company" as defined in Section

                  (b) Each Company Contract is in full force and effect and is a

         neither the Company nor, to the best knowledge of Seller, any other
         party to any Company Contract is in any material respect in breach of
         or in default under any such Company Contract, nor has any event or
         circumstance occurred which, with notice or lapse of time or both,
         would, to the best knowledge of Seller, constitute a material breach or
         default such Company Contract. Neither the Company nor Seller has
         received any notice, and Seller has no reason to believe, that any
         party to any Company Contract intends to cancel or terminate such
         Company Contract or to exercise or not exercise any option thereunder.

<PAGE>   25
any member of the immediate family or affiliate of any of such Persons, or with
any Entity in which any such Person owns any equity, ownership or voting
interest ("Affiliated Person"). The Company has no outstanding loans or other
advances to, and is not a party to any lease, license or other contract
agreement, understanding or arrangement with, any Affiliated Person other than

acknowledge and agree that the maps and other art work decorating the Company's
premises are the property of Seller.

         SECTION 2.35. NO LOSS OF RIGHTS OR LEGAL OBSTACLES. Except as set forth
on Schedule 2.15, the execution and delivery of this Agreement and the Related
Seller Agreements by Seller and its performance of the transactions and its
obligations contemplated hereby and thereby do not and will not (a) result in
any loss or dimunition to the Company of any material legal right, asset,
property, or transaction currently held by the Company; (b) result in any
termination, modification or cancellation of any Contract; (c) result in the
termination, modification or cancellation of, or give rise to any right of

         SECTION 2.36. SECURITIES REPRESENTATIONS AS TO THE ACQUISITION OF THE
PURCHASER SHARES.

                  (a) INVESTMENT INTENT. Seller is acquiring the Purchaser
         Shares solely for his own account, and not as nominee or agent for any
         other Person, for investment purposes only, and not with a view to any
         subsequent offering, resale or distribution of the Purchaser Shares.

                  (b) SOPHISTICATION AND SUITABILITY. Seller has such knowledge
         and experience in business and financial matters to be capable of
         independently evaluating the merits and risks of an investment in the
         Purchaser Shares. Seller has independently evaluated the risks and
         merits of acquiring the Purchaser Shares and has independently
         determined that the Purchaser Shares are a suitable investment for
         Seller. Seller has sufficient financial resources to bear the economic
         risk of a loss of its entire investment in the Purchaser Shares.

                  (c) ACCESS TO INFORMATION. Seller and his representatives have
         made an independent investigation of Purchaser and its assets,
         properties, business, liabilities, financial condition, results of
         operations and prospects. Seller and his representative have had an
         opportunity to ask questions of and to receive answers from
         representatives of Purchaser to the full satisfaction, and have been
         given access to all of the agreements, instruments, financial
         statements and other information concerning the business, assets,
         properties, liabilities, financial condition, results of operations and
         prospects of the Purchaser, and all questions have been answered and
         all information has been provided to the full satisfaction of Seller
         and his representatives, and has had access to all of the information
         they consider necessary or appropriate, in order to evaluate the risks
         and merits of acquiring the Purchaser Shares, and have received all
         information requested to their satisfaction.

                                       19
<PAGE>   26
                  (d) NO RELIANCE. In making his investment decision, Seller has
         not relied upon any representations made by Purchaser with respect to
         Purchaser or the Purchaser Shares (except as set forth in this
         Agreement) or any projections or other estimates or forecasts of future
         performance provided by Purchaser.

                  (e) ACCREDITED INVESTOR. Seller is an "accredited investor" as
         that term is defined in Rule 501(a) of Regulation D promulgated under
         the Securities Act.

                  (f) NO REGISTRATION. Seller understands and acknowledges that
         the Purchaser Shares to be acquired by him hereunder have not been
         registered for offer or sale to Seller under the Securities Act or
         under the securities laws of any state, but are being offered and sold
         by Purchaser to Seller pursuant to and in reliance upon exemptions from
         the registration requirements of such securities laws, and that
         Purchaser is relying upon the truth and accuracy of the
         representations, warranties, covenants and agreements of Seller set
         forth herein in order to determine the availability of such exemptions
         and the suitability of Seller to acquire the Purchaser Shares.

                  (g) RESTRICTIONS ON RESALE. Seller understands and
         acknowledges that, as a consequence of the restrictions on subsequent
         transfer imposed by the exemptions from registration referred to in
         Section 2.36(f) above, the Purchaser Shares may not subsequently be
         offered, sold, assigned, conveyed, pledged, hypothecated or otherwise
         transferred by Seller except pursuant to an effective registration
         statement registering the sale or transfer of the Purchaser Shares
         under the Securities Act and under applicable state securities laws or
         pursuant to an exemption from such registration requirements, and the
         certificates representing the Purchaser Shares shall bear a legend
         setting forth such restrictions substantially as follows:

         THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF
         ANY STATE, AND MAY NOT BE SOLD, ASSIGNED, TRANSFERRED, OR OTHERWISE
         DISPOSED OF UNLESS THE SAME IS REGISTERED UNDER SUCH ACT AND ANY
         APPLICABLE STATE SECURITIES LAWS, OR UNLESS AN EXEMPTION FROM SUCH
         REGISTRATION IS AVAILABLE AND THE COMPANY RECEIVES EVIDENCE OF SUCH
         EXEMPTION REASONABLY SATISFACTORY TO IT (SUCH AS AN OPINION OF
         COUNSEL).

         SECTION 2.37. DISCLOSURE. Neither this Agreement (including the
schedules and exhibits hereto), and the Related Seller Agreements and the
Related Company Agreements, nor any other written or oral certificates,
statements or other documents or information delivered or to be delivered to
Purchaser by Seller or on behalf of the Company in connection with the
transactions contemplated hereby or thereby contains or will contain any untrue
statement of a material fact or omits or will omit to state any material fact
necessary in order to make the statements made herein or therein, in light of
the circumstances in which they were or are made, not false or misleading.
Seller has delivered or disclosed to Purchaser all material information
(financial or otherwise) in the possession of the Seller or the Company
regarding the assets, properties, business, affairs, condition (financial or
otherwise), results of operations or prospects of the Company or which Seller
believes is otherwise material to Purchaser's decision to purchase the Shares.
There is no information known to Seller which has had, or insofar as Seller can
now reasonably foresee, in the future will be

                                       20
<PAGE>   27
reasonably likely to have, a material adverse effect on the Company which is not
set forth in this Agreement or has not been otherwise disclosed in writing to
Purchaser.

         SECTION 2.38. KNOWLEDGE. To the extent that any representation or
warranty in this Article 2 is qualified to Seller's knowledge or awareness,
Seller represents and warrants that he has made a diligent investigation
sufficient to express an informed view concerning the matters to which such
representation or warranty relates, including diligent inquiries of the
Company's directors, officers, employees, consultants and other representatives.

                                    ARTICLE 3
                   REPRESENTATIONS AND WARRANTIES OF PURCHASER

generally relating to or affecting the enforcement of creditors' rights and
remedies and by general privileges of equity, whether applied in a proceeding in
equity or at law.

         SECTION 3.4. NO CONFLICTS. The execution and delivery by Purchaser of
this Agreement and the Related Purchaser Agreements and the performance by
Purchaser of its obligations hereunder and thereunder, do not and will not,
directly or indirectly, violate, conflict with, or constitute a breach of or a
default (or an event that, after the giving of notice or the lapse of time or
both, would constitute a default) under any provision of (a) the Certificate of
Incorporation or By-laws of Purchaser, (b) any resolution adopted by the board

<PAGE>   28

legality of, this Agreement or the transactions contemplated hereby, or (b)
which, if determined adversely to Purchaser, would be reasonably likely to have
a material adverse effect on the ability of Purchaser to perform its obligations
hereunder or to consummate the transactions contemplated hereby.

hereby or thereby.

         SECTION 3.8. CAPITALIZATION AND STATUS OF PURCHASER SHARES.

                  (a) As of the date hereof, the authorized capital stock of
         Purchaser consists of, and subsequent to the TotalPlan Merger (as
         defined below) and immediately prior to the Merger the authorized
         capital stock of the Company will consist of, 60,000,000 shares of
         common stock, par value $.01 per share ("Purchaser Shares"), of which
         17,500,000 shares are and will be issued and outstanding and owned by
         Purchaser, and 1,000,000 shares of preferred stock, par value $.01 per
         share, none of which are or will be outstanding. The Purchaser has
         never issued any Purchaser shares to any Person other than Purchaser.
         No Purchaser Shares are reserved for issuance upon the exercise of
         outstanding options, warrants or other rights. Purchaser has no other
         equity or voting securities of any class or series authorized, issued,
         reserved for issuance or outstanding, and has no outstanding
         securities, bonds, debentures, notes or other rights, instruments or
         obligations the holders of which have the right to vote with the
         holders of Purchaser Shares or which are convertible into or
         exchangeable or exercisable for Purchaser Shares or any other class or
         series of capital stock or equity or voting interests in the Purchaser.
         All of the issued and outstanding shares of capital stock of the
         Purchaser have been duly authorized and validly issued, are fully paid
         and nonassessable, were not issued in violation of any, and are free
         from any, preemptive rights, have no personal liability attached to the
         ownership thereof, and were offered, sold and issued in full compliance
         with all applicable federal and state securities laws. There are no
         outstanding options, warrants or other rights (contingent or otherwise)
         to subscribe for or to purchase from the Purchaser, or obligations,
         agreements, arrangements, understandings or commitments of any nature
         (contingent or otherwise) by the Purchaser to issue, sell, transfer,
         repurchase, redeem or retire, any Purchaser Shares or any other class
         or series of capital stock or other equity securities of the Purchaser,
         or securities which are convertible into or exchangeable or exercisable
         for Purchaser Shares or any other class or series of capital stock or
         other equity or voting interests in the Purchaser. Neither the
         Purchaser nor its sole shareholder is a party to any voting trust,
         voting agreement, proxy or other agreement or arrangement with respect
         to the voting, transferability, purchase or redemption of any capital
         stock of the Purchaser. No Person has any preemptive right, right of
         first refusal, subscription right or similar right with respect to the
         issuance or sale of any of the Purchaser Shares.

                                       22
<PAGE>   29
         No Person has any right of rescission or claim for damages under
         Federal or state securities laws with regard to the offer, sale or
         issuance for, capital shares of the Purchaser previously issued. The
         Purchaser has not agreed, and has no obligation (contingent, absolute
         or otherwise), to register the offer or sale of any of its securities
         owned by any Person under the Securities Act of 1933, as amended
         ("Securities Act"), or the securities laws of any state. Metretek has
         not granted to any Person any options or other rights to purchase any
         capital shares of the Company from Metretek. The representations and
         warranties in this Section 3.8(a) are qualified in their entirety by
         the following:

                           (i) the obligations of Purchaser in connection with
                  this Agreement and the related Purchaser Agreements; and

                           (ii) the adoption by the Purchaser of a 2000 Stock
                  Incentive Plan (the "Purchaser Stock Plan"), authorizing the
                  issuance of 6,000,000 Purchaser Shares, under which options to
                  purchase 1,693,000 Purchaser Shares have been issued through
                  the date hereof, including options to purchase 200,000
                  Purchaser Shares to be granted to Seller on the Closing Date.

                  (b) After the Closing, assuming Seller's compliance with the
         terms of this Agreement and the Related Seller Agreements, Seller will
         acquire good, valid and marketable title to, 2,500,000 Purchaser
         Shares, free and clear of any and all Liens, other than any

         Agreements.

all of the rights and interests therein, whether real, personal or mixed and
whether tangible or intangible, including but not limited to all of the property
and assets reflected in the Purchaser's Latest Balance Sheet and all of the
assets acquired after the date thereof (other than inventory disposed of in the
ordinary course of business since the date thereof), which constitute all of the
assets, properties, rights and interests of every kind and description that are
used in or required for the conduct of the business of the Purchaser in
compliance with all legal requirements. All tangible assets and properties are
physically located at the Purchaser's principal offices in Denver, Colorado.

of trust and other restrictions and encumbrances of any kind or nature
whatsoever, except for (i) those disclosed in the Financial Statements; (ii)

actual and intended uses.

         SECTION 3.10. REAL PROPERTY. Purchaser does not own, has not at any
time owned, and has no obligation to purchase, any real property. Purchaser has
a valid leasehold interest in and enjoys peaceful and quiet possession of all
property leased under the Real Property Leases. Each Real Property Lease is in
full force and effect and is a valid and binding obligation of the Purchaser
and, to the best knowledge of Purchaser, of each of the other parties thereto,
enforceable against each party to each Real Property Lease in accordance with
its terms. Purchaser is not, and does not

                                       23
<PAGE>   30
have any knowledge that at any other party to any Real Property Lease is, in
breach, violation or default (including an event or condition that, with notice
or the passage of time or both, could constitute a default) under any term or
condition of any Real Property Lease.

         SECTION 3.11. PERSONAL PROPERTY LEASES. The Purchaser has a valid
leasehold interest in and enjoys peaceful and quiet possession of all property
leased under the Personal Property Leases. Each Personal Property Lease is in
full force and effect and is a valid and binding obligation of Purchaser and, to

with its terms. Purchaser is not, and does not have any knowledge that at any
other party to any Personal Property Lease is, in breach, violation or default
(including an event or condition that, with notice or the passage of time or
both, could constitute a default) under any term or condition of any Personal
Property Lease.

         SECTION 3.12. ACCOUNTS AND NOTES RECEIVABLE. All accounts and notes
receivable reflected on the latest balance sheet of Purchaser and that have
arisen since the date thereof, other than accounts and notes receivable

fide amounts due for goods delivered and sold or services performed in the
ordinary course of business and in accordance with the applicable warranties,
purchase orders, contracts and specifications, (ii) are not and will not be
subject to any valid defenses, counterclaims or rights of set-off, and (iii)

(iii) engaged in any activity which constitutes a violation of the Foreign
Corrupt Practices Act of 1977, as amended, and the rules and regulations

knowledge of Seller, any other party to any Purchaser Contract in any material
respect in breach of or in default under any such Purchaser Contract, nor has
any event or circumstance occurred which, with notice or lapse of time or both,
would constitute a material breach or default such Purchaser Contract. Purchaser

Purchaser Contract intends to cancel or terminate such Purchaser Contract or to
exercise or not exercise any option thereunder.

         SECTION 3.25. FINANCIAL STATEMENTS. Seller has delivered to Purchaser

and hold harmless Purchaser, its affiliates, successors and assigns, and the
officers, directors, shareholders, partners, employees, agents and
representatives of any of them, from and against, and shall reimburse them for,

(collectively, "Damages") incurred or suffered by Purchaser arising out of,
based upon or resulting from (a) any breach or violation of, inaccuracy or
misrepresentation in, or failure by Seller to perform or to cause the Company to
perform, any of the representations, warranties, covenants, agreements or other
obligations of Seller made in this Agreement or in any schedule, certificate,
exhibit or other document or instrument furnished or to be furnished by Seller

to have the right to own or acquire, any shares of capital stock, or any

securities of, or any other equity, ownership, voting, management or other
interest in, the Company, or (ii) all or any portion of the Merger Consideration
or (iii) any compensation, remuneration or other payment with respect to the
Merger or any of the foregoing rights or interests; or (d) Seller's failure to
obtain the Consent for the Real Estate Lease.

         SECTION 8.2. INDEMNIFICATION BY PURCHASER. Purchaser shall indemnify,
defend and hold harmless Seller, his affiliates, successors and assigns, and the
officers, directors, shareholders, partners, employees, agents and
representatives of any of them, from and against, and shall reimburse them for,
any and all Damages incurred or suffered by Seller arising out of, based upon or
resulting from any breach or violation of, inaccuracy or misrepresentation in,
or failure by Purchaser to perform, any of the representations, warranties,
covenants, agreements or other obligations of the Purchaser made in this
Agreement or in any schedule, certificate, exhibit or other document or
instrument furnished or to be furnished by Purchaser to the Company pursuant to
this Agreement.

         SECTION 8.3. CLAIMS FOR INDEMNIFICATION.

                  (a) Whenever any party hereunder believes it has suffered or
         incurred or is likely to suffer or incur any Damages, or any action or
         proceeding is commenced or threatened or claim is made that could
         result in Damages, which is reasonably likely to give rise to a claim
         ("Claim") for indemnification under this Agreement, the party seeking
         indemnification ("Indemnified Party") shall, upon obtaining knowledge
         thereof, promptly notify in writing (the "Claim Notice") the party
         against whom indemnification is sought ("Indemnifying Party") of the
         Claim and, when known, the facts constituting the basis for such Claim
         and the amount and nature of the Damages or an estimate thereof. The
         Indemnified Party's failure to timely notify Indemnifying Party of any
         Claim or potential Claim shall not relieve the Indemnifying Party of
         any liability hereunder unless and only to the extent that

                                       36
<PAGE>   43
         such failure causes Indemnifying Party to lose the right to assert any
         substantive rights or defenses or to the extent that the Indemnifying
         Party is actually prejudiced in its rights or obligations.

                  (b) The Indemnified Party shall give the Indemnifying Party 30
         days after receipt of the Claim Notice to notify the Indemnified Party
         that it has elected to assume and control the defense of any such Claim
         at the Indemnifying Party's own expense and with counsel selected by
         the Indemnifying Party and reasonably satisfactory to Indemnified
         Party; provided, however, that Indemnified Party shall at all times
         also have the right, but not the obligation, to fully participate in
         the defense of the Claim and to employ its own counsel at its own
         expense. Notwithstanding the foregoing, if the Indemnified Party
         reasonably determines that: (i) legal defenses may be available to the
         Indemnified Party that are different from or in addition to those
         available to the Indemnifying Party; (ii) a conflict or potential
         conflict of interest exists between the Indemnified Party and the
         Indemnifying Party (in which case the Indemnifying Party shall not have
         the right to direct the defense of such Claim on behalf of the
         Indemnified Party); or (iii) the Indemnifying Party (A) did not notify
         the Indemnified Party within 30 days of receipt of the Claim Notice
         that it elected to assume and control the defense of the Claim, or (B)
         has not in fact thereafter reasonably diligently employed legal counsel
         to assume the defense of and vigorously contest such Claim, then the
         reasonable fees, disbursements and other charges of counsel from one
         separate firm selected by the Indemnified Party (and reasonably
         acceptable to the Indemnifying Party) shall be reimbursed by the
         Indemnifying Party promptly as they are incurred.

                  (c) No Party hereto shall compromise, settle or consent to the
         entry of any judgment with respect to any Claim without the prior
         written consent of the other interested party or parties (which consent
         shall not be unreasonably withheld or delayed) unless such compromise,
         settlement or consent includes an unconditional release of all other
         interested parties hereto from any and all liabilities on any Claims
         that are the subject matter thereof.

                  (d) Each party hereto shall cooperate in every reasonable way
         with the party assuming responsibility for the defense and disposition
         of any such Claim, including making available to the defending party
         all books, records, and other material reasonably required by the
         defending party for its use in defending the Claim.

         SECTION 8.4. LIMITATION ON LIABILITY. Notwithstanding the foregoing,
the Indemnifying Party shall not be required to indemnify the Indemnified Party
hereunder (i) unless and until the aggregate amount of all Damages exceeds
$25,000, and then only to the extent of the excess, and (ii) beyond an aggregate
of $1,000,000.

         SECTION 8.5. SURVIVAL. The indemnification obligations set forth in
this Article 8, the representations and warranties set forth in this Agreement,
and, except to the extent otherwise expressly provided herein, the covenants and
agreements set forth in this Agreement shall survive the Closing and shall
continue in full force and effect until they expire on the second anniversary of
the Closing Date, regardless of any investigation made by any party hereto,
except (i) as to any Damages that are due to fraud, which shall expire only upon
the expiration of the applicable statute of limitations, or (ii) as to any
Claims relating to Sections 2.3, 2.4, 2.5, 2.6, 2.7, 2.9 and 2.16, which Claims
shall survive without limitation.

         SECTION 8.6. EFFECT OF KNOWLEDGE. No disclosure to nor investigation by
or on behalf of any party hereto shall be deemed to affect its reliance on the
representations, warranties, covenants

                                       37
<PAGE>   44
and agreements contained herein or to waive its rights to indemnification as
provided herein for the breach or violation of or inaccuracy or failure to
perform or comply with any representation, warranty, covenant or agreement of
any other party hereto.

         SECTION 8.7. CONTRIBUTION. If the indemnification provided for in this
Article 8 is for any reason unavailable or insufficient to indemnify the
Indemnified Party in respect of any Damages, then the Indemnifying Party shall
in lieu of indemnifying the Indemnified Party contribute to the total damages to
which the Indemnified Party may be subject in such proportion that shall be
appropriate to reflect the relative fault of the Indemnifying Party, on the one
hand, and the Indemnified Party, on the other hand, in connection with any
actions or omissions which resulted in such Damages as well as any other
relevant equitable considerations.

                                    ARTICLE 9
                        POST-CLOSING AND OTHER COVENANTS

         SECTION 9.1. FURTHER ASSURANCES. Each of the parties hereto shall use
all reasonable efforts to take, or cause to be taken, all actions, and to do, or
cause to be done, all things necessary, convenient or desirable under applicable
laws and regulations to consummate and make effective the transactions
contemplated by this Agreement. At any time and from time to time after the
Closing, each of the parties shall, at the request of any other party hereto (a
"Requesting Party"), without further consideration, execute, acknowledge and
deliver all further assignments, conveyances, deeds, and other documents and
instruments and take such further actions as a Requesting Party may reasonably
request in order to more fully and effectively consummate the Merger and the
other transactions contemplated hereby.

         SECTION 9.2. MUTUAL COOPERATION. Each of Purchaser and Seller shall
cooperate and cause its respective employees and agents to cooperate with each
other in the preparation of financial and other reports and statements relating
to the Company and its business, affairs and operations for periods ending on or
prior to the Closing Date. In connection with the preparation of any tax
returns, any audit or other examination by any taxing or other Governmental
Authority, or any Proceeding or other matters including, but not limited to,
matters relating to the transactions contemplated by this Agreement, each party
will provide the other with the opportunity to make copies of any records or
information which may be relevant to such return, audit or examination,
Proceeding or determination. Each party shall make its employees available on a
mutually convenient and reasonable basis to provide additional information and
explanation of any material provided hereunder.

         SECTION 9.3. TAXES.

                  (a) PRE-CLOSING. Seller shall be responsible for the timely
         preparation of, for all federal, state, local or foreign income,
         excise, withholding, property, sales, use, franchise and other tax
         returns, reports and forms of Seller or the Company pertaining to the
         Company for all taxable periods ending on or before the Closing Date,
         and for the payment by the Company of all amounts due thereunder, or
         the maintenance as of the Closing Date of adequate cash reserves
         therefor.

                  (b) DUE TO TRANSACTIONS. Seller shall pay all federal, state
         and local sales, use, income, stamp, registration and similar transfer
         taxes and fees arising out of the Merger, whether imposed by law on
         Seller or Purchaser. Seller shall indemnify, reimburse and hold
         Purchaser

                                       38
<PAGE>   45
         harmless in respect of any liability for payment of or failure to pay
         any such taxes or any filing of or failure to file any reports required
         in connection therewith.

         SECTION 9.4. RIGHT OF APPRAISAL. Seller shall be entitled, one time per
calendar year, to obtain an appraisal of Purchaser by a reputable, qualified
outside appraiser, at Seller's sole cost and expense. Such appraisal shall only
be conducted upon reasonable advance notice to Purchaser and subject to the
reasonable security and confidentiality measures required by Purchaser
(including, but not limited to, the requirement that individuals involved in
conducting the appraisal enter into a Confidentiality Agreement in form and
substance reasonably acceptable to Purchaser). Purchaser agrees to cooperate in
this appraisal (so long as such appraisal does not materially impair its
operations), furnishing the appraiser with reasonably requested information;
provided, however, that Purchaser shall charge Seller for its reasonable costs
for any technical resources or extraordinary personnel time spent by Purchaser
unnecessary for such appraisal. Such appraisal shall only be conducted during
normal business hours, and Seller agrees to provide Purchaser with a copy of any
such appraisal promptly after Seller's receipt thereof. Seller acknowledges and
agrees that its right to appraisal is personal to Seller and not transferable or
assignable in any respect to any Person for any reason. This right to appraisal
shall expire (i) on the date Purchaser, or any successor to its business, files
its first Form 10-K or Form 10-KSB, as applicable, or other similar or successor
annual report containing substantially similar information with the Securities
and Exchange Commission; (ii) on the date Seller, for any reason, becomes the
holder of less than 5% of the then outstanding Purchaser Shares; or (iii) one
year after the termination of Purchaser's employment with Purchaser under the
Employment Agreement or any successor employment agreement.

                                   ARTICLE 10

         Any dispute, controversy or claim arises out of, under or in connection
with, or otherwise relating to, this Agreement (a "Dispute"), including but not
limited to the parties' rights and obligations hereunder, or any actual or
alleged breach hereof, shall be determined and settled by binding arbitration in
Denver, Colorado in accordance with the rules of the commercial rules and
procedures of the American Arbitration Association, as amended by this
Agreement. Promptly after a Dispute arises, the parties agree to make a good
faith effort to select one mutually agreeable arbitrator. If the parties are
unable to reach agreement on an arbitrator within thirty (30) days after the
Dispute is submitted to arbitration, one arbitrator shall be selected in
accordance with the commercial rules and procedures of the American Arbitration
Association. Any determination, resolution or award made by the arbitrators
shall specify the findings of fact of the arbitrators and the reasons for the
determination, resolution or award, and such determination, resolution or award
shall be final and binding. If the parties hereto mutually agree to a resolution
of any Dispute prior to the arbitrators' decision, the agreement of the parties
shall resolve the Dispute. The party prevailing in any arbitration, as
determined by the arbitrator, shall be entitled to an award of all of its
out-of-pocket costs and expenses incurred in connection with the Dispute,
including but not limited to reasonable attorneys' fees, court costs and expert
fees. An arbitration award or decision may be entered by any court of competent
jurisdiction, or application may be made to such a court for judicial acceptance
of the award or decision and any appropriate order, including enforcement. The
parties hereby consent to the submission of any Dispute for settlement by
binding arbitration in accordance with this Article 11 and agrees to carry out
without delay the provisions of any arbitration award, decision or resolution.

         inducing Employee to enter into this Agreement and for his services
         hereunder, the Company shall cause Metretek to grant to Employee an
         option (the "Metretek Option") to purchase 60,000 shares of Common
         Stock, par value $.01 per share ("Metretek Common Stock"), of Metretek,
         with an exercise price equal to 110% of the last sale price of the

         date hereof. The Metretek Option shall vest in three equal
         installments: one-third on the date hereof, one-third in six months and

         terminate upon his death, and the Company shall pay to his designated
         beneficiary (or, if none, to his estate) the pro rata portion of his
         Salary and all other accrued and vested but unpaid compensation through
         the date of his death.


                  (b) DISABILITY. The Company shall have the right, in its sole
         discretion, to terminate Employee's employment hereunder in the event
         of Employee's "Disability" upon giving at least 30 days written notice
         to Employee of its intention to terminate Employee's employment. For
         purposes of this Agreement, "Disability" means the physical or mental
         inability of Employee, due to illness, accident or

         duties hereunder for any period of 90 consecutive days, or 180 days
         during any twelve-month period, or which results from an incapacity
         determined to be total and permanent as determined by an independent
         physician selected by the Company.


                  (c) BY THE COMPANY FOR CAUSE. The Company shall have the

         shall be entitled to receive only the accrued but unpaid portion of his
         Salary through the date of termination, plus any accrued and vested but
         unpaid compensation as of such date, but Employee shall not be entitled
         to any bonus or incentive compensation for the year in which he was
         terminated. Employee shall have no right to receive any other or
         further compensation or benefits. For purposes of this Agreement,

                  acknowledgments hereunder, which failure, refusal or breach
                  remains unremedied or uncured for a period of 15 days after

                  Board or any Senior Officer;


                           (ii) Any act of dishonesty, disloyalty,

                           (iii) The conviction of Employee, or the entering of
                  a guilty plea or a plea of no contest by Employee with respect
                  to (A) a felony, or (B) a misdemeanor that involves theft,
                  fraud or dishonesty, results in Employee's imprisonment or

                  property, business, operations or reputation of the Company;


                           (v) The misappropriation (or attempted
                  misappropriation) or embezzlement by Employee of any funds,
                  property, business opportunity or rights of the Company,
                  including securing (or attempting to secure) any personal
                  profit in connection with any transaction entered into on
                  behalf of the Company without the prior consent of the Board;


                           (vi) The breach by Employee of, or failure or refusal
                  of Employee to adhere to, any written code of conduct, policy

                  officers of the Company that is not remedied by Employee
                  within twenty (20) business days after receipt of notice
                  thereof given by the Company;


                           (vii) The use by Employee of drugs, alcohol or
                  narcotics which interferes with the performance of Employee's
                  duties and responsibilities under this Agreement;


                           (viii) The excessive absence by Employee unrelated to
                  illness or permitted leave time; or

                                       4

                           (ix) Gross dereliction, misconduct, neglect,
                  incompetence or insubordination of Employee or mismanagement
                  by Employee in connection with Employee's duties or
                  responsibilities hereunder.


                  (d) BY THE COMPANY WITHOUT CAUSE. The Company shall have the
         right, in its sole discretion, to terminate Employee's employment
         hereunder at any time effective upon the giving of written notice of
         such termination to Employee (or at such later date as the notice
         provides). In such event, Employee shall be entitled to receive (i) all
         amounts of Salary and bonuses accrued but unpaid through the date of
         termination, (ii) an amount equal to the Salary at the rate in effect
         on the date of termination for a period the shorter of twelve months or
         the remainder of the Employment Term, (iii) any rights and benefits of
         any of the employee benefits accruing to him (including any plans in
         which he was participating) as of the date of such termination, subject
         to the terms and conditions of such plans and benefits, but Employee
         shall not attain vested status in any plans or benefits in which he is
         not vested on the date of termination (except as provided in clause
         (iv) below), and (iv) the Metretek Option shall immediately vest and
         become exercisable and remain exercisable for the periods set forth in
         the Metretek Option. In the event of the termination of Employee's
         employment hereunder by the Company without Cause, Employee shall use
         his best efforts to mitigate the amounts payable under this Section
         5(d) hereof by seeking other employment; provided, however, that
         Employee shall not be required to accept a position: (i) of
         substantially different character than the position held by Employee
         with the Company during the Employment Term, or (ii) that might
         reasonably be expected to by result in a violation by Employee of the
         provisions of Section 6. To the extent that Employee shall receive
         compensation and benefits from such other employment for services
         rendered during the remainder of the Employment Term computed without
         regard to the termination, the payments and benefits to be made or
         provided by or at the direction of the Company under the provisions of
         this Section 5(d) shall be correspondingly reduced.


                  (e) VOLUNTARY TERMINATION BY EMPLOYEE. Employee agrees not to
         voluntarily terminate his employment hereunder except by giving at
         least 60 days written notice to the Company. Upon such voluntary
         termination by Employee, Employee shall be entitled to receive only the
         accrued but unpaid portion of his Salary (but not any bonus) through
         the date of termination and the accrued and vested rights and benefits
         under any Employee benefits plan which he was entitled to receive at
         the date of such termination, subject to the terms and conditions of
         such plans.


                  (f) UPON MERGER, ACQUISITION OR CHANGE IN CONTROL OF THE
         COMPANY. Neither this Agreement nor Employee's employment hereunder
         shall terminate solely by reason of any sale of assets or capital stock
         of the Company, or any merger or consolidation or change in control of
         the Company, if Employee is offered employment with the resulting,
         survivor or successor entity on terms and conditions, in the aggregate,
         not materially less favorable to Employee than the terms of this
         Agreement.


                  (g) NO FURTHER OBLIGATION TO EMPLOYEE. The payments and
         benefits (if any) required to be made or provided to Employee pursuant
         to this Section 5 shall be in full and complete satisfaction of, and
         shall constitute the full settlement and release of the Company by
         Employee with regard to all obligations of the Company owed to Employee
         pursuant to this Agreement. After the date of termination of Employee's
         employment hereunder, the Company shall have no further obligations to
         Employee under this Agreement except as otherwise set forth herein.


                  (h) SURVIVAL OF EMPLOYEE'S OBLIGATIONS. Notwithstanding the
         termination of this Agreement by either party hereto for any reason,
         the obligations of Employee under Section 6 hereof and

                                       5
<PAGE>   6
         the other provisions thereof shall survive the termination or
         expiration of this Agreement or Employee's employment hereunder and
         shall remain in full force and effect for the period provided therein.


         SECTION 6. COVENANTS. In consideration in part for the compensation to
be paid to Employee hereunder by the Company, and in order to induce the Company
to enter into this Agreement and the Stock Purchase Agreement, Employee hereby
makes the following covenants to the Company:

                  (a) COVENANT NOT TO COMPETE. During the Employment Term and
         for a period of one year thereafter (the "Restricted Period"), Employee
         shall not, directly or indirectly, alone or in association with others,
         whether as owner, shareholder, employee, officer, director, partner,
         manager, member, lender, investor, consultant, principal, agent,
         independent contractor, co-venturer or in any other capacity, invest
         in, engage in, have a financial interest in, be in any other way
         connected or affiliated with, or render advice or service to, any
         Person that is in competition with the Company in the United States or
         in any other country in which the Company does a material amount of
         business or otherwise has material operations.

                           (i) COMPETITION WITH THE COMPANY. For purposes of
                  this Agreement, (A) the phrase "in competition with the
                  Company" shall be deemed to include competition with the
                  Company and its subsidiaries and Affiliates, or their
                  respective successors or assigns, or the businesses of any of
                  them, and (B) a business shall be deemed to be in competition
                  with the Company if it is engaged in any business activity or
                  has products or services that are the same or similar to the
                  business activities, products or services of the Company
                  during the Employment Term. Notwithstanding the foregoing,
                  nothing herein contained shall prevent Employee from acquiring
                  and holding for investment up to two percent (2%) of any class
                  of securities of any corporation, if such securities are
                  listed or traded on a national securities exchange or the
                  Nasdaq Stock Market or in the over-the-counter market.


                           (ii) INTERPRETATION OF COVENANT. The parties hereto
                  acknowledge and agree that the duration and area for which the
                  covenant not to compete set forth in this Section 6(a) is to
                  be effective are fair and reasonable and are reasonably
                  necessary for the protection of the Company and its business
                  and good will, and Employee hereby waives any objections to or
                  defenses in respect thereof. In the event that any court
                  determines that any portion of the time period or the area, or
                  both of them, are unreasonable, arbitrary or against public
                  policy, and that such covenant is to such extent
                  unenforceable, illegal or invalid, the parties hereto agree
                  that this Section 6(a) shall be deemed amended to delete
                  therefrom such provisions or portions adjudicated to be
                  unenforceable, illegal or invalid so that the covenant shall
                  remain in full force and effect for the greatest time period
                  and in the greatest geographical area that would render it
                  enforceable, legal and valid. The parties intend that the
                  covenant set forth in the Section 6(a) shall be deemed to be a
                  series of separate covenants, one for each and every county of
                  each and every state of the United States of America and one
                  for each and every political subdivision of each and every
                  other country where the covenant is intended to be effective
                  and is not proscribed by law.


                  (b) COVENANT REGARDING DISCLOSURE OR USE OF CONFIDENTIAL
                      INFORMATION.

                           (i) Employee acknowledges that during the Employment
                  Term and as a result of his employment by the Company, he will

                  information regarding the business and affairs of the Company
                  and its Affiliates. Employee hereby agrees that at all times
                  during and after the Employment Term he shall keep strictly
                  confidential and hold in confidence all Confidential
                  Information (as defined below), and shall not, directly or
                  indirectly, use any Confidential Information for Employee's
                  own benefit or for the benefit of any other Person or divulge,
                  disclose, communicate or otherwise reveal any Confidential
                  Information to any Person in any manner

                                       6

                  whatsoever, other than to the directors, employees and agents
                  of the Company, and then only in the course of the Company's
                  affairs to the extent necessary for them to perform services
                  to and responsibilities on behalf of the Company.

                  confidential, proprietary, secret or otherwise non-public
                  information.


                           (iii) Employee hereby acknowledges and agrees that,
                  as between the Company and Employee, all of the Confidential
                  Information, however documented, whether or not developed,
                  created or modified by Employee, is the exclusive property of
                  the Company.


                           (iv) Upon the termination or expiration of the
                  Employment Term, Employee shall leave with or return to the
                  Company, without making or retaining any copies, or other
                  records of, all Confidential Information including all copies,
                  summaries, abstracts thereof and all memoranda, notes,

                  generally available to the public other than as a result of a
                  direct or indirect disclosure by Employee.

         agrees that during and throughout the Employment Term and the
         Restricted Period, except when acting on behalf of the Company, he
         shall not, directly or indirectly, (i) employ, solicit, induce, engage
         or cause any director, officer, employee, independent contractor,

         hereafter engaged by the Company) to (A) terminate his employment or
         engagement with the Company, (B) accept employment or engagement or

         become and remain the sole and exclusive property of the Company.
         Employee hereby acknowledges that all of Employee's writing, works of
         authorship and other Intellectual Property are works made for hire and
         the property of the Company, including patents, trademarks, service
         marks, copyrights and other intellectual property rights pertaining
         thereto. Employee shall, at the request and cost of the Company or any
         of its Affiliates, render assistance as the Company deems necessary or
         desirable to secure, prosecute and/or defend the rights thereto by
         patent, trademark, service mark, copyright to otherwise to the Company
         or its Affiliates, including without limitation the assignment,
         transfer and conveyance to the Company or its Affiliates of all of
         Employee's right, title and interest in and to the Intellectual
         Property.

                  (e) EMPLOYEE'S ACKNOWLEDGMENT. The Company spends considerable
         amounts of time, money and effort in developing and maintaining good
         will in its industry. Employee agrees the covenants contained within
         this Section 6 (i) are reasonable and necessary in all respects to
         protect the goodwill, trade secrets, confidential information, and
         business interests of the Company; (ii) are not oppressive to Employee;
         (iii) do not impose any greater restraint on Employee than is
         reasonably necessary to protect the goodwill, trade secrets,
         confidential information and legitimate business interests of the
         Company; and (iv) will not, upon the termination, of Employee's
         employment with the Company for any reason whatsoever, cause Employee
         to be unable to earn a living that is suitable and acceptable to
         Employee.

                  (f) EQUITABLE RELIEF.Employee hereby acknowledges and agrees
         that his services to be rendered to the Company hereunder and his
         obligations contained in this Section 6 are of special, unique and
         personal character which gives them a peculiar value to the Company,
         that the Company cannot be reasonably or adequately compensated in
         money damages in an action at law in the event Employee breaches any
         obligations under this Section 6, and that the provisions of this
         Section 6 are reasonable and necessary to protect the business of the
         Company. Employee therefore expressly agrees that, in addition to any
         other rights or remedies which the Company may have at law or in equity
         or by reason of any other agreement, the Company shall be entitled to
         injunctive and other equitable relief in the form of temporary,
         preliminary and permanent injunctions without posting bond or other
         security in the event of any actual or threatened breach of any such
         obligation by Employee and without the necessity of proving actual
         damages, and to discontinue any salary, bonus, benefits and/or
         insurance continuation provided hereunder. Nothing in this Agreement
         shall be construed to prohibit the Company from pursuing any other
         remedy, and Employee agrees that all remedies of the Company are
         cumulative.

                  (g) NATURE OF COVENANTS. Employee's covenants in Section 6
         hereof are independent covenants, and the existence of any claim by
         Employee against the Company under this Agreement or otherwise will not
         excuse Employee's breach or waive Employee's obligation to perform, any
         covenant in this Section 6. If Employee's employment hereunder
         terminates for any reason, or the Employment Term expires, this Section
         6, and the other terms and conditions of this Agreement necessary or
         appropriate to enforce the covenants of Employee in Section 6, shall
         survive and remain in full force and effect.

                                       8
<PAGE>   9
         SECTION 7. REPRESENTATIONS AND WARRANTIES OF EMPLOYEE. Employee
represents and warrants to the Company that (a) Employee is under no contractual
or other restriction, arrangement or obligation which is or will be breached by
or in conflict or inconsistent with his execution and delivery of this
Agreement, the performance of his duties hereunder, or the other rights of the
Company hereunder, and (b) Employee is under no physical or mental disability or
incapacity that would hinder the performance of his duties under this Agreement.

         SECTION 8. CONSOLIDATION, MERGER OR SALE OF ASSETS. Nothing in this
Agreement shall preclude the Company from consolidating with, merging into, or
transferring all or substantially all of its assets to another entity which
assumes all of the Company's obligations and undertakings hereunder. Upon such a
consolidation, merger or transfer of assets, the term "Company" as used herein
shall mean such other entity, and this Agreement shall continue in full force
and effect.

         SECTION 9. EMPLOYEE ACKNOWLEDGMENT; COUNSEL. Employee acknowledges by
executing this Agreement and delivering it to the Company that (i) he has read
all of the terms and conditions hereof, including his obligations, covenants,
representations and warranties to the Company; (ii) the covenants of Employee in
Section 6 hereof are essential elements of this Agreement, and the Company would
not have entered into this Agreement or the Stock Purchase Agreement without
Employee's agreement to comply with such covenants; (iii) each and every term,
covenant and restriction is reasonable and necessary for the proper protection
of the Company's business; and (iv) he has been advised by the Company that he
should consult with independent counsel of his choice and have such counsel
review this Agreement and render advice thereon to Employee, and Employee has
either done so or voluntarily elected not to do so.

         SECTION 10. TAXES. All payments required to be made by the Company
hereunder to Employee shall be subject to withholding of such amounts relating
to taxes as the Company may reasonably determine it should withhold pursuant to
any applicable federal, state or local law or regulation. In lieu of withholding
such amounts, in whole or in part, the Company may, in its sole discretion,
accept other provision for payment of taxes, provided it is satisfied that all
requirements of law affecting its responsibilities to withhold such taxes have
been satisfied.

         SECTION 11. NO ATTACHMENT. Except as required by law, no right to
receive payment under this Agreement shall be subject to anticipation,
commutation, alienation, sale, assignment, encumbrance, charge, pledge or
hypothecation or to execution, attachment, levy, or similar process of
assignment by operation of law, and any attempt, voluntary or involuntary, to
effect any such action shall be null, void and of no effect.

         SECTION 12. ARBITRATION. Any dispute, controversy or claim arises out
of, under or in connection with, or otherwise relating to, this Agreement (other
than the Company's rights under Section 6) (a "Dispute"), including but not
limited to the parties' rights and obligations hereunder, or any actual or
alleged breach hereof, shall be determined and settled by binding arbitration in
Denver, Colorado in accordance with the rules of the commercial rules and
procedures of the American Arbitration Association, as amended by this
Agreement. Promptly after a Dispute arises, the parties agree to make a good
faith effort to select one mutually agreeable arbitrator. If the parties are
unable to reach agreement on an arbitrator within thirty (30) days after the
Dispute is submitted to arbitration, one arbitrator shall be selected in
accordance with the commercial rules and procedures of the American Arbitration
Association. Any determination, resolution or award made by the arbitrators
shall specify the findings of fact of the arbitrators and the reasons for the

                                       9
<PAGE>   10
determination, resolution or award, and such determination, resolution or award
shall be final and binding. If the parties hereto mutually agree to a resolution
of any Dispute prior to the arbitrators' decision, the agreement of the parties
shall resolve the Dispute. The party prevailing in any arbitration, as
determined by the arbitrator, shall be entitled to an award of all of its
out-of-pocket costs and expenses incurred in connection with the Dispute,
including but not limited to reasonable attorneys' fees, court costs and expert
fees. An arbitration award or decision may be entered by any court of competent
jurisdiction, or application may be made to such a court for judicial acceptance
of the award or decision and any appropriate order, including enforcement. The
parties hereby consent to the submission of any Dispute for settlement by
binding arbitration in accordance with this Section 14 and agrees to carry out
without delay the provisions of any arbitration award, decision or resolution.

         SECTION 13. GENERAL PROVISIONS.

                  (a) GOVERNING LAW. This Agreement shall in all respects be
         governed by, and construed in accordance with, the internal substantive
         laws of the State of Colorado, without giving effect to any conflict or
         choice of law principles or rules.

                  (b) AMENDMENT. This Agreement may not be amended or modified
         in whole or in part in any manner except in a writing which makes
         reference to this Agreement executed by both parties hereto.

                  (c) ASSIGNMENT. Neither the Agreement, nor any rights,
         obligations or duties hereunder, may be assigned or delegated by any
         party hereto without the prior written consent of the other party
         hereto; provided, however, that this Agreement shall inure to the
         benefit of and be binding upon the successors and assigns of the
         Company upon any sale of all or substantially all of the Company's
         stock or assets, or upon any merger, consolidation or reorganization of
         the Company with or into any other Person, so long as such successors
         or assigns assume all of the Company's obligations hereunder. As used
         in this Agreement, the term "Company" shall be deemed to refer to any
         such successor or assign of the Company referred to in the preceding
         sentence.

                  (d) SUCCESSORS AND ASSIGNS. This Agreement shall inure to the
         benefit of and be binding upon the parties hereto and their respective
         successors and permitted assigns.

                  (e) ENTIRE AGREEMENT.

                           (i) This Agreement sets forth the entire agreement
                  and understanding of the parties hereto with respect to the
                  subject matter hereof and supersedes in their entirety all
                  prior and contemporaneous written and oral agreements,
                  arrangements, understandings, negotiations, communications,
                  covenants, representations and warranties among the parties
                  hereto relating to the subject matter hereof.

                           (ii) Employee acknowledges that from time to time,
                  the Company may establish, maintain or distribute the employee
                  manuals or handbooks or personnel policy manuals, and officers
                  or other representatives of the Company may make written or
                  oral statements relating to personal policies and procedures.
                  Such manuals, handbooks and statements are intended only for
                  general guidance. No policies, procedures or statements of any
                  nature by or on behalf of the Company (whether written or
                  oral, and whether or not contained in any the employee manual
                  or handbook or personnel policy manual), and no acts or
                  practices of any nature, shall be construed to modify this
                  Agreement.

         Any party hereto may send any notice, demand, request, election or
         other communication to the intended recipient at its address set forth
         above using any other means (such as expedited courier, messenger
         service, telecopy, telex, ordinary mail or electronic mail), but no
         such notice, demand, request or other communication shall be deemed to
         have been given until it is actually received by the recipient. Any

         to the benefits the obligations so involved. Any waiver of a breach or
         violation of or default under any provision of this Agreement shall not
         be construed or operate as, or constitute, a waiver of any other or
         subsequent breach or violation of or default under that provision or
         any other provision of this Agreement. The failure of any party to
         insist upon strict compliance with any provision of this Agreement on

         right to insist upon strict compliance with, that provision or any
         other provision of this Agreement.

                  (h) SEVERABILITY. The provisions of this Agreement shall be
         deemed severable. If any provision of this Agreement is determined to
         be illegal, invalid or unenforceable in any situation: (i) the parties
         hereto shall agree to a suitable and equitable provision to be
         substituted therefor in order to carry out, so far as may be valid and
         enforceable, the intent and purpose of such invalid or unenforceable
         provision; and (ii) the remainder of this Agreement shall remain in
         full force and effect, and the application of such provision in any
         other situation shall not be affected.

                  (i) COUNTERPARTS. This Agreement may be executed in any number
         of counterparts (including counterparts executed by less than all
         parties hereto), each of which shall be deemed to be an original, but
         all of which together shall constitute one and the same instrument.

                  (j) HEADINGS. The headings used herein are solely for
         convenience of reference and shall not be given any effect in the
         construction or interpretation of this Agreement.

                  (k) NO THIRD PARTY BENEFICIARIES. Nothing in this Agreement,
         express or implied, in intended to create or confer and shall not be
         construed or operate as creating or conferring, any rights or remedies
         under or by reason of this Agreement, upon any Person other than the
         parties hereto and their respective successors and permitted assigns.

                  (l) FURTHER ASSURANCES. The parties hereto agree to take or
         cause to be taken all actions, which are necessary, convenient or
         desirable in order to effect the transactions contemplated by this
         Agreement.

<PAGE>   13
                  (m) BEST EFFORTS. Each of the parties hereto shall act in good
         faith and use its best efforts to bring about the transactions
         contemplated by this Agreement.

                  (n) EXPENSES. Except as otherwise expressly provided herein,
         each of the parties to this Agreement shall pay its own costs and
         expenses incurred in connection with this Agreement and the
         consummation of the transactions contemplated hereby.

                  (o) CONSTRUCTION. In the event an ambiguity or question or
         intent or interpretation arises, this Agreement shall be construed as
         if drafted jointly by the parties hereto and no presumption or burden
         of proof shall arise favoring or disfavoring any party hereto by virtue
         of the authorship of any of the provisions of this Agreement.

                  (p) SPECIFIC PERFORMANCE. Each of the parties hereto
         acknowledges and agrees that the other parties hereto would suffer
         irreparable damage for which an adequate remedy at law would not be
         available in the event any of the provisions of this Agreement is not
         performed in accordance with its specific terms or otherwise is
         breached. Accordingly, each of the parties hereto agrees that the
         non-breaching parties shall be entitled to an injunction, restraining
         order or other form of equitable relief from any court of competent
         jurisdiction to prevent breaches of, and to specifically enforce, the
         provisions of this Agreement.

                  (q) INTERPRETATION OF CERTAIN PROVISIONS. Except as otherwise
         expressly provided herein, as used in this Agreement:

                           (i) Any reference to any federal, state, local or
                  foreign statute or law shall be deemed also to include a
                  reference to all rules and regulations promulgated thereunder.

                           (ii) The term "including" means "including, without

                  venture, trust, association, unincorporated organization,
                  governmental or regulating body or authority, or any other
                  form of business or entity.

                           (iv) The term "Person" means and includes an
                  individual and an Entity.

                           (v) The number and gender of each noun and pronoun
                  and the terms "Person" and "Persons" and the like shall be
                  construed to mean such number and gender as the context, the
                  circumstances or its antecedent may require.

                           (vi) The terms "hereof", "herein", "hereunder" and
                  words of similar import refer to this Agreement as a whole,
                  and not to any Section, subsection or clause of this
                  Agreement.

                           (vii) Each reference to a Section means such Section
                  of this Agreement.

SECTION 3. RIGHTS OF REFUSAL.
           -----------------

         3.1 Right of First Refusal.

                  (a) Notice of Offer. If Harpole desires to Transfer any or all
         of the Harpole Shares (the "Offer") at or above a particular purchase
         price (the "Offer Price") (the Shares subject to the Offer hereinafter
         referred to as the "Offered Shares"), then Harpole shall first offer
         such Shares at the Offer Price (the "Offer") and give notice of the
         Offer (the "Notice of Offer"), to the Company and to Metretek. The
         Notice of Offer shall include the number of Offered Shares, the Offer
         Price and, if any specific Transfer is then contemplated by Harpole,
         the terms of the proposed Transfer in reasonable detail, including the
         name and address of the prospective purchaser, and the other material
         terms of the Offer. The Notice of Offer shall also contain an
         irrevocable Offer to sell the Offered Shares to the Company and
         Metretek upon the terms and conditions of the Rights of Refusal set
         forth in this Agreement.

                  (b) Company's Right of First Refusal. The Company shall have
         the irrevocable first right and option (the "Right of First Refusal")
         to purchase any or all of the Offered Shares upon the terms and
         conditions set forth in this Section 3.1(b); provided that the Company
         may not purchase any of the Offered Shares unless the Company and
         Metretek have, collectively, agreed to purchase all of the Offered
         Shares. The Company may exercise its Right of First Refusal by giving
         written notice of such exercise (the "Notice of Exercise") to Harpole
         on or before the thirtieth (30th) day after the Company shall have
         received the Notice of Offer from Harpole. The Notice of Exercise shall
         specify the number of Offered Shares the Company desires to purchase.

                  (c) Notice of Re-Offer. If the Company declines to exercise
         its Right of First Refusal with respect to all of the Offered Shares,
         then the Company shall give notice of that effect (the "Re-Offer
         Notice") to Metretek promptly after making such decision, but in no
         event later than the thirtieth (30th) day after the Company shall have
         received the Notice of Offer. The Re-Offer Notice shall specify the
         number of Offered Shares which the Company shall have declined to
         purchase (the "Remaining Available Shares") and shall be accompanied by
         a copy of the Notice of Exercise, if any.

         3.2 Right of Second Refusal.

                  (a) Metretek's Right of Second Refusal.Upon receipt of the
         Re-Offer Notice, Metretek shall have the irrevocable right and option
         (the "Right of Second Refusal") to purchase all, but not less than all,
         of the Remaining Offered Shares which the Company shall have declined
         to purchase.

                  (b) Exercise of Right of Second Refusal. Metretek may exercise
         its Right of Second Refusal for all of the Remaining Offered Shares by
         giving written notice of such exercise to Harpole on or before the
         fifteenth (15th) day after Metretek shall have received the Re-Offer
         Notice from the Company.

                  3.3 Purchase Price. The Purchase Price to be paid for each
         Offered Share purchased by the Company or Metretek in accordance with
         this Section 3 shall be the Offer Price for such Offered Share as set
         forth in the Notice of Offer, and shall be paid on the same terms set
         forth in the Offer or, at the option of the Purchaser, by check or wire
         transfer of immediately

                                       4
<PAGE>   8
         available funds, at the Closing, or by any other means mutually
         acceptable to the Purchaser and Harpole.

         3.4 Closing of Rights of Refusal. The Closing of the purchase and sale
of the Offered Shares pursuant to this Section 3 shall take place at the
principal place of business of the Company on a date forty-five (45) business
days after the date the Company receives the Notice of Offer, unless the
Purchaser and Harpole mutually agree on a different place or time. At the
Closing, Harpole shall deliver to the Purchaser all certificates representing
the Offered Shares duly endorsed in blank, or with duly endorsed blank stock
powers attached, and otherwise in proper form for Transfer, against payment by
each Purchaser by bank cashiers or certified check, or by wire transfer of
immediately available funds to an account designated by Harpole, of the Purchase
Price for the Offered Shares such Purchaser is purchasing, pursuant to the terms
and conditions of the Offer, as modified as permitted by this Agreement or by
Harpole, in his sole discretion. Upon Transfer, Harpole shall conclusively be
deemed, unless the Purchaser, in his sole discretion, permitting otherwise in
writing, to have given the following representations and warranties to the
Purchasers, which shall survive the Closing: (A) Harpole is the legal,
beneficial and record owner of the Offered Shares being purchased and sold, has
good and marketable title thereto and the absolute right to Transfer the same to
the Purchaser, and such Offered Shares, upon Transfer to the Purchaser, will be
free and clear of all security interests, pledges, claims, liens, option, rights
of first refusal, limitations or voting rights and restrictions of any kind
whatsoever (other than restrictions imposed by this Agreement and by federal and
state securities laws); and (B) the Transfer of Offered Shares by Harpole as
contemplated by this Agreement does not require any consent or approval of any
governmental authority, court or other Person that has not already been
obtained.

         3.5 Sale to Prospective Purchaser. If the Right of First Refusal and
the Right of Second Refusal (collectively, the "Rights of Refusal") shall not in
the aggregate have been timely exercised for the purchase of all (100%) of the
Offered Shares, then Harpole shall have the right, for a period ending 180 days
after the earlier of (i) the day the Second Right of Refusal expires, or (ii)
the day Harpole receives notice that the Company and Metretek will not exercise
their Rights of Refusal to purchase 100% of the Offered Shares, to Transfer all,
but not less than all, of the Offered Shares free of the Rights of Refusal to
any other Person (the "Offered Shares Purchaser") at the same price and
otherwise upon the same terms (or at a price that is greater than and/or upon
terms more favorable to Harpole than) described in the Offer. If Harpole does
not Transfer the Offered Shares to the Prospective Purchaser within such 180-day
period, then the Transfer by Harpole of the Offered Shares will be again subject
to the Rights of Refusal. It shall be a condition of the effectiveness of the
Transfer of the Offered Shares to an Offered Shares Purchaser that (i) at least
ten (10) business days prior to the Closing of the sale of the Offered Shares to
the Offered Shares Purchaser, Harpole shall give written notice to the Company

not, within 10 business days after such notice, have given written notice to
Harpole that it is exercising its right, in its reasonable discretion, to reject
to the Offered Shares Purchaser for valid business reasons, in its reasonable
discretion, and (ii) the Offered Shares Purchaser shall have agreed in writing
with the Company and Metretek to become a party to this Agreement as a
Shareholder, and to be bound by and to comply with all the terms of this
Agreement applicable to Harpole, and that the Offered Shares so purchased shall
be subject to all of the restrictions applicable to the Harpole Shares set forth

Section 3 to the contrary, the following Transfers (collectively, the "Permitted

         Harpole or an Entity owned or controlled by Harpole or any Relation of
         Harpole, for no considerations (provided the transferee complies with
         the provisions in clause (ii) of the last sentence of Section 3.5 as if
         the transferee were an Offered Shares Purchaser);

                  (d) any Transfer of Shares by Harpole to Metretek;

                  (f) any Transfer of Shares made by Harpole that has been
         approved in writing by Metretek.

         3.7 Securities Act Matters. Notwithstanding any other provision of this
Agreement to the contrary, but subject to express written waiver by the Company
in the exercise of its good faith and reasonable judgment, Harpole shall not
make any Transfer of Shares without the registration of the Transfer of such
Shares under the Securities Act and applicable state securities laws or until
the Company shall have received such legal opinions or other assurances that
such Transfer is exempt from the registration requirements under the Securities
Act and applicable state securities laws as the Company in its good faith and
reasonable discretion deems appropriate in light of the fact and circumstances
relating to such proposed Transfer, together with such representations,
warranties and indemnifications from the transferor and the transferee as the
Company in its good faith and reasonable discretion deems appropriate to confirm
the accuracy of the facts and circumstances that are the basis for any such
opinion or other assurances and to protect the Company and the other
Stockholders from any liability resulting from any such Transfer.

SECTION 4. CO-SALE RIGHTS.
           --------------

         4.1 Co-Sale Rights. In the event Metretek desires to Transfer all or
part of its Shares for value to an unaffiliated third party ("Co-Sale
Purchaser"), then Harpole shall have the right ("Co-Sale Right"), subject to
applicable law and compliance with any other restrictions applicable to such
Transfer, to participate in such Transfer in accordance with this Section 4.

         4.2 Co-Sale Notice. Metretek may Transfer any Shares pursuant to
Section 4 only if (i) the Co-Sale Purchaser agrees to provide Harpole with the
right to participate in the Transfer of the Shares to such Co-Sale Purchaser
upon the same terms and conditions as Metretek, and (ii) Metretek first notifies
Harpole, in writing, of such intended Transfer at least fifteen days prior to
the proposed date of Transfer (the "Co-Sale Notice"). The Co-Sale Notice shall
set forth in reasonable detail the terms of the Transfer, the date on or about
which such Transfer is to be consummated, the number of Shares to the
Transferred, and the name and address of the Co-Sale Purchaser.

                                       6
<PAGE>   10
         4.3 Exercise of Co-Sale Right.If Harpole desires to exercise his
Co-Sale Right under this Section 5, then Harpole shall notify Metretek in
writing within ten (10) days after receipt of the Co-Sale Notice that he will
sell to either the Prospective Purchaser or to Metretek, at Metretek's option, a
number of Shares on the same terms and conditions as the Selling Stockholder set
forth in the Co-Sale Notice. If the Co-Sale Purchaser will not purchase all of
the Shares which Harpole wishes to sell pursuant to this Section 4, then the
number of Shares which Harpole may Transfer pursuant to this Section 4 shall be
equal to the product obtained by multiplying (x) the total number of Shares
being purchased by the Co-Sale Purchaser, by (y) a fraction, (i) the numerator
of which is the total number of Shares owned by Harpole, and (ii) the
denominator of which is the total number of shares owned by Harpole and
Metretek.

         4.4 Exceptions. Notwithstanding any other provision of this Section 4
to the contrary, the Co-Sale Right of Harpole set forth in this Section 4 shall
not apply to the following Transfers:

                  (i) any Transfer of Shares made by Metretek in connection with
         an IPO;

                  (ii) any Transfer of Shares by Metretek to Harpole;

                  (iii) any Transfer of Shares by Metretek to the Company;

                  (iv) any Trust of Shares by Metretek to an Affiliate of
         Metretek or the Company; or

                  (v) any other Transfer of Shares that has been approved in
         writing by Harpole

SECTION 5. DRAG-ALONG RIGHT.
           ----------------

         5.1 Drag-Along Right. If Metretek desires to Transfer all of its Shares
in any transaction with an unaffiliated third party ("Drag-Along Purchaser"),
then Metretek shall have the right (the "Drag-Along Right"), subject to
applicable law and compliance with any other restrictions applicable to such
Transfer, to require Harpole to Transfer, and Harpole hereby agrees to Transfer,
all of the Shares then owned by Harpole to the Drag-Along Purchaser, upon the
same terms and conditions as applicable to Metretek.

         5.2 Drag-Along Notice. In order to exercise its Drag-Along Right,
Metretek shall give written notice to Harpole at least 15 days prior to the
proposed date of Transfer (the "Drag-Along Notice"). The Drag-Along Notice shall
set forth in reasonable detail the terms and conditions of the Transfer, the
date on which such Transfer is to be consummated, and the name and address of
the Drag-Along Purchaser.

         5.3 Agreement. If Metretek exercises its Drag-Along Right, then Harpole
shall agree to enter into a purchase agreement in form and substance approved by
Metretek to the extent such Agreement shall contain customary representations
from Harpole as to the ownership of the Shares to be purchased in the absence of
liens thereon and customary indemnification provisions solely with respect to
such representations from Harpole. Harpole shall not be required to participate
in a proposed Transfer pursuant to the exercise of the Drag-Along Right unless
his liability for breaches of representations and warranties made in connection
with the Transfer is limited to no more than the total sales price received by
Harpole in such sale.

SECTION 6. REGISTRATION RIGHTS.
           -------------------

         6.1 Piggy-Back Registration.

                  (a) Right to Piggy-Back. If, at any time during the period
         commencing on the date after an IPO and ending three years thereafter
         (the "Registration Period"), the Company proposes to register with the
         Securities and Exchange Commission (the "SEC") the sale for cash of any
         of its Shares of common stock by filing a registration statement under
         the Securities Act, for its own account or for the account of any of
         its stockholders (except pursuant to registration statements filed on
         Form S-4 or Form S-8 or any successor or similar forms or other
         unsuitable forms), the Company shall promptly give written notice of
         such proposed filing to each Initial Stockholder and offer each Initial
         Stockholders the opportunity to register such number of Shares owned by
         the Initial Stockholders (the "Registerable Shares") as it may request
         in writing. Upon the written request of an Initial Stockholder received
         by the Company within fifteen (15) days after the giving of the notice
         by the Company, the Company shall use its best efforts to cause the
         number of Registerable Shares that the Initial Stockholder requests to
         be so registered to be included in such registration.

                  (b) Underwriting Procedures. If any registration pursuant to
         this Section 12(a) shall be, in whole or in part, in connection with an
         underwritten public offering of Common Stock of the Company, then the
         Company shall not be required to include any Registerable Shares in the
         registration unless such Initial Stockholder accepts the terms and
         conditions of the underwriting as agreed upon between the Company and
         the underwriters. If the managing underwriter determines and advises
         the Company in writing (which shall promptly notify such Initial
         Stockholder) that the inclusion in the underwriting of all or any of
         the Registerable Shares proposed to be included by the Initial
         Stockholder would be reasonably likely to jeopardize the successful
         marketing of the securities proposed to be registered for the
         underwriting by the Company or materially adversely affect the price,
         time or distribution of the public offering, then the Company shall
         only be required to include the number of the Registerable Shares of an
         Initial Stockholder that the managing underwriter determines, in its
         sole discretion, will not materially adversely affect the public
         offering, and, if any such reduction is so determined by the managing
         underwriter to be appropriate in accordance with the standards set
         forth above, then the number of Registerable Shares requested to be
         included in the underwriting by the Initial Stockholders shall be
         reduced, pro rata among such Initial Stockholders to the number
         determined to be appropriate by the managing underwriter (which may
         include a reduction to zero).

                  (c) No Company Obligation. Neither the giving of a notice by
         the Company nor any request by an Initial Stockholder under this
         Section 6(a) shall, in any way, obligate the Company to file any
         registration statement at any time or within any specific time period
         after receipt of an Initial Stockholder's written request and,
         notwithstanding the filing of any registration statement, the Company
         may, at any time before the effective date thereof, elect to delay or
         terminate the entire registration process for any reason or no reason
         and without the consent of an Initial Stockholder, without any further
         obligation to an Initial Stockholder in respect of such registration
         statement.

         6.2 Demand Right. If, at any time during the Registration Period, the
Company shall receive a written request ("Demand Request") from an Initial
Stockholder for the registration of any or all of the Registerable Shares of the
Initial Stockholder, then the Company, upon the terms and subject to the
conditions set forth in this Section 6.2, shall use its best efforts to cause
all such Registerable Shares to be registered in an appropriate registration
statement of the SEC

                                       8
<PAGE>   12
as shall be selected by the Company, provided that if the Company is eligible to
use Form S-3 (or any successor form thereto) for such registration, then such
registration statement shall be used unless such form is inappropriate or the
Company desires to use a different form. If an Initial Stockholder intends for
the public offering covered by its Demand Request to occur by means of an
underwriting, it shall so advise the Company as a part of its Demand Request,
and the managing underwriter of such underwritten public offering shall be
selected by such Initial Stockholder and shall be reasonably acceptable to the
Company. The Company shall be obligated to register the Registerable Shares of
any Initial Stockholder under this Section 6.2 after receipt of a Demand Request
on one occasion per Initial Stockholder only. The Company shall be entitled to
include in any registration statement filed pursuant to this Section 6.2
additional shares of capital stock for its own account and for the account of
its other security holders. If the managing underwriter advises the Company in
writing that the inclusion of any or all such additional shares of capital stock
would materially adversely affect the marketing of the public offering of the
Registerable Shares of any Initial Stockholder, then the Company shall not be
entitled to include such additional shares of capital stock in any such
registration statement to the extent the managing underwriter advises.
Notwithstanding the provisions of this Section 6.2, the Company shall have the
right to delay or suspend the filing of a registration statement for up to
ninety (90) days from the time the filing thereof would otherwise be required
under this Section 6.2 if, in the good faith determination of the Company's
board of directors, such registration would be seriously detrimental to the
Company and its stockholders or would materially adversely affect the business,
affairs, properties, financial condition, results of operations or prospects of
the Company or any pending or proposed acquisition, merger, reorganization,
recapitalization or other transaction or public offering of the Company's
securities, or would require premature disclosure thereof not in the best
interests of the Company; provided, however, that the Company shall not be
entitled to exercise this right more than once.

         6.3 Information. It shall be condition precedent to the obligation of
the Company hereunder to register the Registerable Shares under this Section 6
that an Initial Stockholder furnish to the Company and the managing underwriters
such information regarding itself, the intended method of disposition of such
securities and such other information as the Company or the managing underwriter
shall from time to time reasonably request and that shall be reasonably required
to effect the registration of the Registerable Shares.

         6.4 Market Stand-Off. Each Initial Stockholder agrees in connection
with any underwritten public offering of the Company's securities that, upon the
request of the managing underwriter, it shall commit itself in writing not to
sell or offer to sell any shares other than such shares included in the
underwritten public offering, during 30 days prior to, and for a period not to
exceed 180 days after, the date of the final prospectus used in such offering.

         6.5 Expenses. Each Initial Stockholder shall pay all underwriting and
brokerage fees, discounts and commissions and other selling expenses related to
the sale of its Registerable Shares in a public offering registered pursuant to
the provisions of this Section 6, together with the fees and expenses of any
separate counsel, accountants and other advisors retained by an Initial
Stockholder in connection with the offering. All other fees, costs and expenses
incurred in connection with any registration of public offering including, but
not limited to, all federal and state registration, qualification, filing fees,
printed and document distribution costs and expenses, fees and disbursements of
its counsel, accountants and other experts, Nasdaq additional listing fees,
transfer fees, exchange fees, fees of transfer agents and registrants shall be
borne as follows: (i) if pursuant to a Demand Request under Section 6.2, the
Company shall bear all reasonable costs, fees and expenses incurred by the
Company (provided the offering being registered is not pursuant to an

                                       9
<PAGE>   13
underwriting), except if the public offering is underwritten at the request of
an Initial Stockholder, then the Company and such Initial Stockholder shall
share equally all such fees, and (ii) if pursuant to a piggy-back registration
under Section 6.1, by the Company.

         6.6 Indemnification by Initial Stockholder. If any of the Registration
Shares of an Initial Stockholder are included in a registration, to the extent
permitted by law, Initial Stockholder shall indemnify and hold harmless the
Company, each of its directors, each of its officers who have signed the
registration statement, each person, if any, who controls the Company within the
meaning of Section 15 of Securities Act or Section 20 of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), any underwriter, and any
controlling person of any such underwriter, from and against any and all losses,
claims, liabilities, damages and expenses (including any investigative, legal,
accounting and other expenses reasonably incurred in connection with, and any
amount paid in settlement of, any action, suit or proceeding or any claim (the
"Damages") asserted to which any of the foregoing persons may become subject
under the Securities Act, the Exchange Act, or other federal or state law,
common law or otherwise, insofar as such Damages arise out of or are based upon
any untrue statement or alleged untrue statement of a material fact contained in
such registration statement, any preliminary prospectus or final prospectus, or
any amendments or supplements thereto, the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, or any violation or alleged violation by the
Company of the Securities Act, the Exchange Act, any state securities law or any
rule or regulation promulgated under the Securities Act, the Exchange Act or any
state securities law (collectively, a "Violation"), to the extent that such
Violation occurs in reliance upon and in conformity with written information
furnished to the Company by the Initial Stockholder expressly for use in
connection with such registration; and Initial Stockholder shall pay, as
incurred, any legal or other expenses reasonably incurred by any person intended
to be indemnified pursuant to this Section 6.6 in connection with the
investigation or defense of any such Damages.

         6.7 Indemnification by the Company. If any of the Registerable Shares
of an Initial Stockholder are included in a registration, to the extent
permitted by law, the Company shall indemnify and hold harmless such Initial
Stockholder, each of its directors and officers from and against any and all
Damages asserted to which any of the foregoing persons may become subject under
the Securities Act, the Exchange Act, or other federal or state law, common law
or otherwise, insofar as such Damages arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in such
registration statement, any preliminary prospectus or final prospectus, or any
amendments or supplements thereto, the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, or any Violation or alleged Violation by such
Initial Stockholder, to the extent that such Violation occurs in reliance upon
and in conformity with written information furnished to such Initial Stockholder
by the Company expressly for use in connection with such registration; and the
Company shall pay, as incurred, any legal or other expenses reasonably incurred
by any person intended to be indemnified pursuant to this Section 6.7 in
connection with the investigation or defense of any such Damages.

SECTION 7. PUT RIGHT.
           ---------

         7.1 Put Right. Harpole shall have the right (the "Put Right") to
require the Company to repurchase all of the Shares he then owns (the "Put
Shares") on the terms and conditions set forth in this Section 8.

                                       10
<PAGE>   14

         7.2 Put Exercise Period. The Put Right shall be exercisable, on one
occasion only, at any time during the one-year period (the "Put Exercise
Period") commencing on the second anniversary of the date of this Agreement, if,
and only if, (i) prior to such exercise the Company shall not have consummated
any of the following: (A) an IPO; (B) a sale of all or substantially all of its
assets or business; (C) a merger, consolidation, reorganization or similar
transaction pursuant to which all or substantially all of its assets, business,
capital stock or voting power shall have been Transferred to one or more Persons

substantially all of its capital stock to an unaffiliated third party; and (ii)
Harpole shall not, at the time of exercise, be in material breach of any term or
condition of this Agreement.

         7.3 Put Price. The Purchase Price to be paid for the Put Share

the value of such Put Shares as determined in the written opinion of an
appraiser (the "Put Appraiser"). The Put Appraiser shall be The Wallach Company,
Inc., ("Wallach") or, if either the Company or Harpole reject, in its reasonable
discretion, Wallach within twenty (20) business days after Harpole gives the Put
Notice (as defined below) to the Company, then Harpole shall designate another
qualified appraiser that is unaffiliated with Harpole and that is an investment
banking firm or otherwise in the business of conducting, and is qualified to
conduct, an appraisal of businesses such as the business of the Company. The
designation of a Put Appraiser by Harpole shall be subject to the approval of
Metretek, which approval shall not be unreasonably withheld and will be deemed
to have given absent the Company delivering to Harpole written notice of
objection to such designation within ten (10) business days after receipt of
written notice of the name, address and other reasonable identification of the
Put Appraiser from Harpole. Harpole shall pay all costs and expenses of the Put
Appraiser. Harpole shall cause a signed copy of the appraisal conducted by the
Put Appraiser (the "Put Appraisal") to be delivered to the Company.

         7.4 Mechanics of Exercise. Harpole shall exercise his Put Right at any
time during the Put Exercise Period by giving written notice thereof to the
Company (the "Put Notice").

         7.5 Closing of Put Right. The Closing of the purchase and sale of the
Put Shares pursuant to this Section 8 shall take place at the principal place of
business of the Company no later than fifteen (15) business days after the date
the Company receives a copy of the Put Appraisal, unless the Company and Harpole
mutually agree on a different place or time. At the Closing, Harpole shall
deliver to the Company all certificates representing the Put Shares duly
endorsed in blank, or with duly endorsed blank stock powers attached, and
otherwise in proper form for Transfer, against payment by the Company of the Put
Price in the manner set forth in Section 8.6. At the Closing, Harpole shall
conclusively be deemed, unless the Company, in its sole discretion, permits
otherwise in writing, to have given the following representations and warranties
to the Company, which shall survive the Closing: (A) Harpole is the legal,
beneficial and record owner of the Put Shares, as good and marketable title
thereto and the absolute right to Transfer the same to the Company, and the Put
Shares, upon Transfer to the Company, will be free and clear of all security
interests, pledges, claims, liens, options, right to first refusal, limitations
on voting rights and restrictions of any kind whatsoever (other than
restrictions imposed by this Agreement and by federal and state securities
laws); and (B) the Transfer of the Put Shares by Harpole as contemplated by this
Agreement does not require any consent or approval of any governmental
authority, court or other Person that has not already been obtained.

         7.6 Payment of Purchase Price.In the event that the Company shall
purchase the Put Shares at the Closing, then at the Closing the Company shall
pay to Harpole, out of funds

                                       11
<PAGE>   15
legally available for repurchase of the Put Shares under Delaware law,
one-fourth of the Purchase Price by check or by wire transfer of immediately
available funds to an account designated by Harpole; and shall deliver to
Harpole a Promissory Note evidencing the Company's obligation to pay Harpole the
balance of the Put Price in three equal annual installments of principal, each
installment being due and payable on the anniversary date of the Closing (each,
a "Payment Date"), along with accrued and unpaid interest from the date of
Closing on the unpaid principal balance at a rate of interest equal to 8% per
annum. The Company shall have the right to prepay all or any part of the
indebtedness evidenced by the Promissory Note at any time or from time to time,
without premium, penalty or other charge, and the amount of any such prepayment
shall be applied first to interest accrued on the unpaid principal balance of
such indebtedness, and second to the unpaid balance of such indebtedness. Upon
default on the payment of any installment due on the Promissory Note, which
default is not cured within thirty (30) days after notice of such default is
given to the Company by Harpole, then the rate of interest on the unpaid
principal balance owed to Harpole under the Promissory Note shall be increased
to a rate equal to 12% per annum.

         7.7 Inability of Company. If the Company is legally or otherwise unable
to pay the Put Price on the terms set forth in Section 7.5, then the Company
shall take all reasonable action to remove the impediments to the payment of the
Put Price, and the Company shall pay the Put Price at the earliest possible
time. Notwithstanding the foregoing, Metretek shall not be obligated to
contribute any additional capital to the Company.

SECTION 8. DILUTION MATTERS.
           ----------------

otherwise mutually agreed in writing, neither Metretek nor Harpole shall have
any right, preemptive or otherwise, to subscribe for, purchase or otherwise
acquire any shares of capital stock or other equity securities of the Company,
or any securities convertible into or exercisable or exchangeable for any shares
of capital stock or other equity securities of the Company, or any options,
warrants or other rights to acquire any of the foregoing ("New Purchaser
Securities"), in connection with the offer, issuance, sale or exchange by the

issuance, sale or exchange is made in connection with any investment by outside
investors, issuance in exchange for services, founders' stock issuances, stock
option plans and programs, warrant issuances or otherwise.

         8.2 Metretek Funding of Purchaser. Prior to the date of this Agreement,
Metretek has provided substantial assets and funds to, and paid expenses for the
benefit of, the Company ("Capital Contributions") for the purpose of funding the
initial stages of its development and organization, including financing a

the benefit of the Company. Within 15 business days of the date of this
Agreement, Metretek agrees to make additional Capital Contributions to the
Company in an amount equal to (i) $6,000,000, less (ii) the cumulative amount of
Capital Contributions made by Metretek to or for the benefit of the Company
(including TotalPlan, Inc.) from inception through the date of this Agreement
(the "Required Capital Contributions"). In exchange for such $6,000,000 of
Required Capital Contributions, Metretek shall be entitled to receive a total of
17,500,000 Shares, such total number of Shares to include the number of Shares
issued to Metretek prior to the date hereof, the number of Shares received by
Metretek upon the merger of TotalPlan, Inc. and the Company, and the number of
Shares to be issued in consideration of the additional capital contributions
made after the date hereof (up to the amount of the Required Contributions).

<PAGE>   16
under no obligation to provide any additional funds to or make any further
capital investments in the Company beyond the Required Capital Contributions,
the Company and Harpole acknowledge and agree that after Metretek has met the
Required Capital Contributions, then with respect to any and all additional
Capital Contributions, it makes in or provides to or for the benefit of the
Company, Metretek shall have the right to elect, in its sole discretion, either
(i) to receive additional Shares, at the rate of $0.30 per Share, or (ii) to
treat the excess funds as loans, repayble by the Company on terms reflecting
then current market prices rates.

SECTION 9. HARPOLE'S RIGHTS AS A DIRECTOR.
           ------------------------------

Shares of the Company, (i) Harpole shall have the right to be a member of the
Board of Directors of the Company and (ii) Metretek agrees to vote all its
Shares, at any meeting of the stockholders for the purpose of electing
directors, or to execute a consent in writing in lieu thereof, in order to elect
Harpole as a director of the Company. This right of Harpole to be a director of
the Company (i) shall expire on the second anniversary of the date of this
Agreement, and (ii) shall be personal to Harpole and shall not be assignable or
transferable to any Person, whether or not an Affiliate or Relative of Harpole,

         take all steps necessary to implement such action, including calling a
         special meeting of Stockholders or executing or causing to be executed,

take any and all action as a Shareholder of the Company as may be necessary to
cause the Company to provide such rights and benefits and to comply with such
obligations, commitments, covenants, and agreements.

         10.6 No Contrary Action. No Shareholder shall take any action as an
officer, director or shareholder of the Company which would prevent such Initial

right available to the Payee. No conduct of the Payee shall be deemed to be a
waiver or release of such liability, unless the Payee expressly releases such
person in writing.

         7. Severability. If any term or provision of this Note or the
application thereof to any person, property or circumstance shall to any extent
be determined to be invalid or unenforceable, then all other terms and
provisions of this Note, and the application of such invalid or unenforceable
term or provision to persons, properties and circumstances other than those as
to which this Note is invalid or unenforceable, shall not be affected thereby,
and to that end the terms and provisions of this Note shall be severable, and
each term and provision of this Note shall be valid and enforceable to the
fullest extent permitted by law.

         8. No Waiver. No delay or omission by the Payee in exercising any right
or power arising under this Note shall impair any such right or power or be
deemed to be a waiver of any such right or power, nor shall any single or
partial exercise of any right or power preclude other or further exercise
thereof, or the exercise of any other right or power hereunder or otherwise. No
waiver or modification of the terms of this Note shall be valid unless set forth
in writing executed by the Payee, and a waiver on one or more occasions will not
be construed as a consent to or a waiver of any of the Payee's rights or
remedies on any future occasions.

         9. Governing Law. This Note shall be governed by and construed in
accordance with the internal substantive laws of the State of Colorado, without

         outstanding under the Note) and this Agreement;

<PAGE>   3
                  (d) All renewals, extensions and modifications of any of the
         indebtedness and obligations referred to in the foregoing clauses, or
         any part thereof.

         3. Debtor's Representations, Warranties and Covenants. Debtor hereby
represents, warrants and covenants to and for the benefit of Secured Party, as
follows:

         Debtor has all requisite right, power and authority to execute,
deliver, and perform its obligations under, this Agreement and the Note. The
execution, delivery and performance of this Agreement and the Note by Debtor
have been duly authorized by all requisite corporate action on the part of
Debtor and do not and will not violate or conflict with the articles of
incorporation or bylaws of Debtor or any law, rule or regulation applicable to
Debtor or any order, writ, injunction or decree of any court, government
authority or arbitrator, applicable to Debtor, and do not and will not conflict
with, result in a breach of or constitute a default under the provisions of any
material mortgage, deed of trust, indenture, security agreement, loan agreement,
credit agreement or other instrument, agreement or contract binding on Debtor or
any of its property. Debtor has the unrestricted right to grant the security
interest in the Collateral contemplated hereby.

         4. Events of Default. Debtor shall be deemed to be in default
hereunder, and an Event of Default hereunder shall be deemed to have occurred,
upon the occurrence of any of the following events:

                  (a) Debtor's failure to pay when due, or duly and promptly to
         observe or perform, any of the Obligations;

                  (b) Debtor otherwise breaches (whether or not such breaches
         are within Debtor's control) any covenants, warranties or
         representations in or regarding this Agreement or the Note, and fails
         to remedy such breach within 20 business days of receiving written
         notice of such breach from Secured Party; or

                  (c) Debtor becomes insolvent, terminates its existence,
         dissolves or experiences business failure; a custodian, as that term is
         defined in Title 11, U.S.C., as amended, of any of Debtor's property is
         appointed or exists; or Debtor makes any assignment for the benefit of
         creditors; or any proceeding under any bankruptcy or insolvency law is
         commenced by or against Debtor.

         5. Remedies.

                  (a) If an Event of Default occurs and is continuing hereunder,
         Secured Party shall have full power and authority to sell, assign or
         deliver the whole or any part of the Collateral at any broker's
         exchange or elsewhere, at public or private sale, at the option of
         Secured Party, in order to satisfy any part of the obligations of
         Debtor now existing or hereinafter arising under the Note. On any such
         sale, Secured Party or its assigns may purchase all or part of the
         Collateral. In addition, at its sole option, Secured Party may elect to
         retain all the Collateral in full satisfaction of Debtor's obligations
         under the Note, in accordance with the provisions and procedures set
         forth in the Colorado Uniform Commercial Code.

                                       3
<PAGE>   4
                  (b) The rights and remedies granted to Secured Party herein
         upon an Event of Default shall be in addition to all the rights, powers
         and remedies of Secured Party under the Colorado Commercial Code and
         applicable law and such rights, powers and remedies will be exercisable
         by Secured Party with respect to all of the Collateral. Debtor agrees
         that Secured Party's reasonable expenses of holding the Collateral,
         preparing it for resale or other disposition, and selling or otherwise
         disposing of the Collateral, including attorneys' fees and other legal
         expenses, will be deducted from the proceeds of any sale or other
         disposition and will be included in the amounts Debtor must tender to
         redeem the Collateral. All rights, powers and remedies of Secured Party
         shall be cumulative and not alternative. Any forbearance or failure or
         delay by Secured Party in exercising any right, power or remedy
         hereunder shall not be deemed to be a waiver of any such right, power
         or remedy and any single or partial exercise of any such right, power
         or remedy hereunder will not preclude the further exercise thereof.

         6. Attorney-in-Fact. Debtor hereby appoints Secured Party as the
attorney-in-fact for Debtor for the purpose of carrying out the provisions of
this Agreement and taking any action and executing any instrument which Secured
Party may deem necessary or advisable to accomplish the purposes hereof, which
appointment is irrevocable and coupled with an interest. Without limiting the
generality of the foregoing, Secured Party shall have the right and power to
receive, endorse and collect all checks and other orders for the payment of
money made payable to Debtor and included within the Collateral and to give full
discharge for the same. Neither Secured Party nor any director or officer of any
issuer of the Securities shall have any liability for the distribution to and
collection of the Proceeds by Secured Party, but shall be fully protected in
relying on the written statement of Secured Party as to its authorization
pursuant to this paragraph. Any and all amounts collected by Secured Party
pursuant hereto shall be applied against the Obligations in the manner that
Secured Party shall determine, in Secured Party's sole and absolute discretion.

         7. Certain Other Rights of Secured Party.

                  (a) Duty of Care. Secured Party's only duty with respect to
         the Collateral shall be to exercise reasonable care to secure the safe
         custody thereof. Secured Party shall not have a duty to fix or preserve
         rights against prior parties to the Collateral, and shall never be
         liable for its failure to use diligence to collect any amount payable
         with respect to the Collateral, but shall be liable only to the account
         of Debtor for what Secured Party may actually collect or receive
         thereon.

                  (b) Financing Statement. Secured Party shall have the right at
         any time to execute and file this Agreement or a copy of this Agreement
         as a financing statement, but the failure of Secured Party to do so
         shall not impair the validity or enforceability of this Agreement.

                  (c) Payment of Expenses. At Secured Party's option, Secured
         Party may discharge taxes, liens and interest, perform or cause to be
         performed, for and on behalf of Debtor, any actions and conditions,
         obligations or covenants which Debtor has failed or refused to perform
         and may pay for the repair, maintenance or preservation of any of the
         Collateral, and all sums so expended, including, but not limited to,
         attorneys' fees, court costs, agents' fees or

                                       4
<PAGE>   5
         commissions, or any other costs or expenses, shall bear interest from
         the date of payment at the highest legal rate and shall be deemed to
         constitute part of the Obligations secured by this Agreement.

         8. Cumulative Rights and Remedies. All rights and remedies of Secured
Party hereunder are cumulative of each other and of every other right or remedy
which Secured Party may otherwise have at law or in equity or under any other
contract or other writing for the enforcement of the security interest herein or
the collection of the Obligations, and the exercise by Secured Party of one or
more rights or remedies shall not prejudice or impair the concurrent or
subsequent exercise of other rights or remedies. Should Debtor have heretofore
executed or hereafter executed any other security agreement in favor of Secured
Party in which a security interest is created as security for the debts of
another or others, in respect of which Debtor may not be personally liable, the
security interest therein created and all other rights, powers and privileges
vested in Secured Party by the terms thereof shall exist concurrently with the
security interest created herein, and, in addition, all property in which
Secured Party holds a security interest under any such other security agreement
shall also be part of the Collateral hereunder, and all or any part of the
proceeds of the sale or disposition of such property may, in the discretion of
Secured Party, be applied by Secured Party in accordance with the terms hereof,
and of such other security agreement or agreements, or any of them.

         9. Termination. Upon payment and performance in full by Debtor of all
Obligations in accordance with their terms, this Agreement and the security
interest granted hereunder shall terminate.

         10. Further Assurances. Debtor agrees to execute and deliver such
further instruments and take such further actions as Secured Party may
reasonably request from time to time to preserve or give effect to its rights
under this Agreement.

         11. Arbitration. In the event that any dispute, controversy or claim
arises out of, under or in connection with, or otherwise relates to, this
Agreement, including, but not limited to, the parties' rights and obligations
hereunder, or to the actual or alleged breach or termination hereof, then the
parties hereto agree that the same shall be resolved, determined and settled by
final and binding arbitration in Denver, Colorado utilizing the procedures set
forth in Section 11 of the Merger Agreement.

         12. General Provisions.

         12.1 Governing Law. This Agreement shall in all respects be governed
by, and construed in accordance with, the internal substantive laws of the State
of Colorado, without giving effect to any conflict or choice of law principles
or rules.

         12.2 Amendment. This Agreement may not be amended or modified in whole

                            INDEMNIFICATION AGREEMENT
                            -------------------------

         This Agreement is made as of this ___ day of _________ ("Agreement"),
by and between Metretek Technologies, Inc., a Delaware corporation (the
"Company," which term shall include, where appropriate, any Entity (as
hereinafter defined) controlled directly or indirectly by the Company), and
______________ ("Indemnitee").

         WHEREAS, it is essential to the Company that it be able to retain and
attract as directors the most capable persons available;

         WHEREAS, increased corporate litigation has subjected directors to
litigation risks and expenses, and the limitations on the availability of
directors and officers liability insurance have made it increasingly difficult
for the Company to attract and retain such persons;

         WHEREAS, the Company's Restated Certificate of Incorporation and
Amended and Restated By-laws permit it to indemnify its directors to the fullest
extent permitted by law and permit it to make other indemnification arrangements
and agreements;

         WHEREAS, the Company desires to provide Indemnitee with specific
contractual assurance of Indemnitee's rights to full indemnification against
litigation risks and expenses (regardless of, among other things, any amendment
to or revocation of such Certificate of Incorporation or By-laws or any change
in the ownership of the Company or the composition of its Board of Directors);
and

         WHEREAS, Indemnitee is relying upon the rights afforded under this
Agreement in becoming a director of the Company.

         NOW, THEREFORE, in consideration of the promises and the covenants
contained herein, the Company and Indemnitee do hereby covenant and agree as

         managing member or other similar interest or (ii) (A) 50% or more of
         the voting power of the voting capital equity interests of such

         2. Services of Indemnitee. In consideration of the Company's covenants
and commitments hereunder, Indemnitee agrees to serve or continue to serve as a
director of the Company. However, this Agreement shall not impose any obligation

beyond any period otherwise required by law or by other agreements or
commitments of the parties, if any.

         3. Agreement to Indemnify. The Company agrees to indemnify Indemnitee

         any Proceeding (other than an action by or in the right of the Company)
         by reason of Indemnitee's Corporate Status, Indemnitee shall be
         indemnified by the Company against all Expenses and Liabilities
         incurred or paid by Indemnitee in connection with such Proceeding
         (referred to herein as "Indemnifiable Expenses" and "Indemnifiable
         Liabilities," respectively, and collectively as "Indemnifiable
         Amounts").

                                       2
<PAGE>   3
                  (b) Subject to the exceptions contained in Section 4(b) below,
         if Indemnitee was or is a party or is threatened to be made a party to
         any Proceeding by or in the right of the Company to procure a judgment
         in its favor by reason of Indemnitee's Corporate Status, Indemnitee
         shall be indemnified by the Company against all Indemnifiable Expenses.

                  (c) Notwithstanding the foregoing, the Company shall not be
         obligated to pay the Indemnitee for Expenses or Liabilities to the
         extent the Company's Officers' and Directors' Insurance Carrier has
         already paid the Indemnitee such amounts pursuant to the Company's
         Officers' and Directors' Liability Insurance Policy.

         4. Exceptions to Indemnification. Indemnitee shall be entitled to
indemnification under Sections 3(a) and 3(b) above in all circumstances other
than the following:

                  (a) If indemnification is requested under Section 3(a) and it
         has been adjudicated finally by a court of competent jurisdiction that,
         in connection with the subject of the Proceeding out of which the claim
         for indemnification has arisen, Indemnitee failed to act (i) in good
         faith and (ii) in a manner Indemnitee reasonably believed to be in or
         not opposed to the best interests of the Company, or, with respect to
         any criminal action or proceeding, Indemnitee had reasonable cause to
         believe that Indemnitee's conduct was unlawful, Indemnitee shall not be
         entitled to payment of Indemnifiable Amounts hereunder.

                  (b) If indemnification is requested under Section 3(b) and

                           (i) it has been adjudicated finally by a court of
                  competent jurisdiction that, in connection with the subject of
                  the Proceeding out of which the claim for indemnification has
                  arisen, Indemnitee failed to act (A) in good faith and (B) in
                  a manner Indemnitee reasonably believed to be in or not
                  opposed to the best interests of the Company, Indemnitee shall
                  not be entitled to payment of Indemnifiable Expenses
                  hereunder; or

                           (ii) it has been adjudicated finally by a court of
                  competent jurisdiction that Indemnitee is liable to the
                  Company with respect to any claim, issue or matter involved in
                  the Proceeding out of which the claim for indemnification has
                  arisen, including, without limitation, a claim that Indemnitee
                  received an improper personal benefit, no Indemnifiable
                  Expenses shall be paid with respect to such claim, issue or
                  matter unless the Court of Chancery or another court in which
                  such Proceeding was brought shall determine upon application
                  that, despite the adjudication of liability, but in view of
                  all the circumstances of the case, Indemnitee is fairly and
                  reasonably entitled to indemnity for such Indemnifiable
                  Expenses which such court shall deem proper.

                  (c) Any other provision herein to the contrary
         notwithstanding, the Company shall not be obligated pursuant to the
         terms of this Agreement:

                           (i) To indemnify or advance Expenses to the
                  Indemnitee with respect to Proceedings initiated or brought
                  voluntarily by the Indemnitee and not by way of defense,
                  EXCEPT with respect to Proceedings specifically authorized by
                  the Board or brought to

                                       3
<PAGE>   4
                  establish or enforce a right to indemnification and/or
                  advancement of Expenses arising under this Agreement, the
                  charter or bylaws of the Company or any subsidiary or any
                  statute or otherwise;

                           (ii) To indemnify the Indemnitee hereunder for any
                  amounts paid in settlement of a Proceeding unless the Company
                  consents in advance in writing to such settlement, which
                  consent shall not be unreasonably withheld; or

                           (iii) To indemnify the Indemnitee for Liabilities in
                  connection with a judgment against the Indemnitee on a claim
                  for an accounting of profits made from the purchase or sale by
                  the Indemnitee of securities of the Company pursuant to the
                  provisions of Section 16(b) of the Securities Exchange Act of
                  1934, as amended.

         5. Procedure for Payment of Indemnifiable Amounts. Indemnitee shall
submit to the Company a written request specifying the Indemnifiable Amounts for
which Indemnitee seeks payment under Section 3 of this Agreement and the basis
for the claim. The Company shall pay such Indemnifiable Amounts to Indemnitee
within twenty (20) calendar days of receipt of the request. At the request of
the Company, Indemnitee shall furnish such documentation and information as are
reasonably available to Indemnitee and necessary to establish that Indemnitee is
entitled to indemnification hereunder.

         6. Indemnification for Expenses of a Party Who is Wholly or Partly
Successful. Notwithstanding any other provision of this Agreement, and without
limiting any such provision, to the extent that Indemnitee is, by reason of
Indemnitee's Corporate Status, a party to and is successful, on the merits or
otherwise, in any Proceeding, Indemnitee shall be indemnified against all
Expenses reasonably incurred by Indemnitee or on Indemnitee's behalf in
connection therewith. If Indemnitee is not wholly successful in such Proceeding
but is successful, on the merits or otherwise, as to one or more but less than
all claims, issues or matters in such Proceeding, the Company shall indemnify
Indemnitee against all Expenses reasonably incurred by Indemnitee or on
Indemnitee's behalf in connection with each successfully resolved claim, issue
or matter. For purposes of this Agreement, the termination of any claim, issue
or matter in such a Proceeding by dismissal, with or without prejudice, shall be
deemed to be a successful result as to such claim, issue or matter.

         7. Effect of Certain Resolutions. Neither the settlement or termination
of any Proceeding nor the failure of the Company to award indemnification or to
determine that indemnification is payable shall create an adverse presumption
that Indemnitee is not entitled to indemnification hereunder. In addition, the
termination of any proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent shall not create a presumption
that Indemnitee did not act in good faith and in a manner which Indemnitee
reasonably believed to be in or not opposed to the best interests of the Company
or, with respect to any criminal action or proceeding, had reasonable cause to
believe that Indemnitee's action was unlawful.

         8. Agreement to Advance Expenses; Conditions. The Company shall pay to
Indemnitee all Indemnifiable Expenses incurred by Indemnitee in connection with
any Proceeding, including a Proceeding by or in the right of the Company, in
advance of the final

                                       4
<PAGE>   5
disposition of such Proceeding. To the extent required by Delaware law,
Indemnitee hereby undertakes to repay the amount of Indemnifiable Expenses paid
to Indemnitee if it is finally determined by a court of competent jurisdiction
that Indemnitee is not entitled under this Agreement to indemnification with
respect to such Expenses. This undertaking is an unlimited general obligation of
Indemnitee.

         9. Procedure for Advance Payment of Expenses. Indemnitee shall submit
to the Company a written request specifying the Indemnifiable Expenses for which
Indemnitee seeks an advancement under Section 8 of this Agreement, together with
documentation evidencing that Indemnitee has incurred such Indemnifiable
Expenses. Payment of Indemnifiable Expenses under Section 8 shall be made no
later than twenty (20) calendar days after the Company's receipt of such
request.

         10. Remedies of Indemnitee.

                  (a) Right to Petition Court. In the event that Indemnitee
         makes a request for payment of Indemnifiable Amounts under Sections 3
         and 5 above or a request for an advancement of Indemnifiable Expenses
         under Sections 8 and 9 above and the Company fails to make such payment
         or advancement in a timely manner pursuant to the terms of this
         Agreement, Indemnitee may petition the Court of Chancery to enforce the
         Company's obligations under this Agreement.

                  (b) Burden of Proof. In any judicial proceeding brought under
         Section 10(a) above, the Company shall have the burden of proving that
         Indemnitee is not entitled to payment of Indemnifiable Amounts
         hereunder.

                  (c) Expenses. The Company agrees to reimburse Indemnitee in
         full for any Expenses incurred by Indemnitee in connection with
         investigating, preparing for, litigating, defending or settling any
         action brought by Indemnitee under Section 10(a) above, or in
         connection with any claim or counterclaim brought by the Company in
         connection therewith.

                  (d) Validity of Agreement. The Company shall be precluded from
         asserting in any Proceeding, including, without limitation, an action
         under Section 10(a) above, that the provisions of this Agreement are
         not valid, binding and enforceable or that there is insufficient
         consideration for this Agreement and shall stipulate in court that the
         Company is bound by all the provisions of this Agreement.

                  (e) Failure to Act Not a Defense. The failure of the Company
         (including its Board of Directors or any committee thereof, independent
         legal counsel or stockholders) to make a determination concerning the
         permissibility of the payment of Indemnifiable Amounts or the
         advancement of Indemnifiable Expenses under this Agreement shall not be
         a defense in any action brought under Section 10(a) above, and shall
         not create a presumption that such payment or advancement is not
         permissible.

         11. Defense of the Underlying Proceeding.

                                       5
<PAGE>   6
                  (a) Notice by Indemnitee. Indemnitee agrees to notify the
         Company promptly upon being served with any summons, citation,
         subpoena, complaint, indictment, information, or other document
         relating to any Proceeding which may result in the payment of
         Indemnifiable Amounts or the advancement of Indemnifiable Expenses
         hereunder; provide, however, that the failure to give any such notice
         shall not disqualify Indemnitee from the right to receive payments of
         Indemnifiable Amounts or advancements of Indemnifiable Expenses unless
         the Company's ability to defend in such Proceeding is materially and
         adversely prejudiced thereby.

                  (b) Defense by Company. Subject to the provisions of the last
         sentence of this Section 11 (b) and of Section 11 (c) below, the
         Company shall have the right to defend Indemnitee in any Proceeding
         which may give rise to the payment of Indemnifiable Amounts hereunder;
         provided, however that the Company shall notify Indemnitee of any such
         decision to defend within ten (10) days of receipt of notice of any
         such Proceeding under Section 11 (a) above. The Company shall not,
         without the prior written consent of Indemnitee, consent to the entry
         of any judgment against Indemnitee or enter into any settlement or
         compromise which (i) includes an admission of fault of Indemnitee or
         (ii) does not include, as an unconditional term thereof, the full
         release of Indemnitee from all liability in respect of such Proceeding,
         which release shall be in form and substance reasonably satisfactory to
         Indemnitee. This Section 1l(b) shall not apply to a Proceeding brought
         by Indemnitee under Section 10(a) above or pursuant to Section 19
         below.

                  (c) Indemnitee's Right to Counsel. Notwithstanding the
         provisions of Section 11 (b) above, if in a Proceeding to which
         Indemnitee is a party by reason of Indemnitee's Corporate Status,
         Indemnitee reasonably concludes that it may have separate defenses or
         counterclaims to assert with respect to any issue which may not be
         consistent with the position of other defendants in such Proceeding, or
         if the Company fails to assume the defense of such proceeding in a
         timely manner, Indemnitee shall be entitled to be represented by
         separate legal counsel of Indemnitee's choice at the expense of the
         Company. In addition, if the Company fails to comply with any of its
         obligations under this Agreement or in the event that the Company or
         any other person takes any action to declare this Agreement void or
         unenforceable, or institutes any action, suit or proceeding to deny or
         to recover from Indemnitee the benefits intended to be provided to
         Indemnitee hereunder, Indemnitee shall have the right to retain counsel
         of Indemnitee's choice, at the expense of the Company, to represent
         Indemnitee in connection with any such matter.

         12. Representations and Warranties of the Company. The Company hereby
represents and warrants to Indemnitee as follows:

                  (a) Authority. The Company has all necessary power and
         authority to enter into, and be bound by the terms of, this Agreement,
         and the execution, delivery and performance of the undertakings
         contemplated by this Agreement have been duly authorized by the
         Company.

                  (b) Enforceability. This Agreement, when executed and
         delivered by the Company in accordance with the provisions hereof,
         shall be a legal, valid and binding obligation of the Company,
         enforceable against the Company in accordance with its terms, except as
         such

                                       6
<PAGE>   7
         enforceability may be limited by applicable bankruptcy, insolvency,
         moratorium, reorganization or similar laws affecting the enforcement of
         creditors' rights generally.

         13. Insurance. The Company shall, from time to time, make the good
faith determination whether or not it is practicable for the Company to obtain
and maintain a policy or policies of insurance with a reputable insurance
company providing Indemnitee with coverage for losses from wrongful acts, and to
ensure the Company's performance of its indemnification obligations under this
Agreement. Among other considerations, the Company will weigh the costs of
obtaining such insurance coverage against the protection afforded by such
coverage. In all policies of director and officer liability insurance,
Indemnitee shall be named as an insured in such a manner as to provide
Indemnitee the same rights and benefits as are accorded to the most favorably
insured of the Company's officers and directors. Notwithstanding the foregoing,
the Company shall have no obligation to obtain or maintain such insurance if the
Company determines in good faith that such insurance is not reasonably
available, if the premium costs for such insurance are disproportionate to the
amount of coverage provided, or if the coverage provided by such insurance is
limited by exclusions so as to provide an insufficient benefit. The Company
shall promptly notify Indemnitee of any good faith determination not to provide
such coverage.

         14. Contract Rights Not Exclusive. The rights to payment of
Indemnifiable Amounts and advancement of Indemnifiable Expenses provided by this
Agreement shall be in addition to, but not exclusive of, any other rights which
Indemnitee may have at any time under applicable law, the Company's By-laws or
Certificate of Incorporation, or any other agreement, vote of stockholders or
directors (or a committee of directors), or otherwise, both as to action in
Indemnitee's official capacity and as to action in any other capacity as a
result of Indemnitee's serving as a director of the Company.

         15. Successors. This Agreement shall be (a) binding upon all successors
and assigns of the Company (including any transferee of all or a substantial
portion of the business, stock and/or assets of the Company and any direct or
indirect successor by merger or consolidation or otherwise by operation of law)
and (b) binding on and shall inure to the benefit of the heirs, personal
representatives, executors and administrators of Indemnitee. This Agreement
shall continue for the benefit of Indemnitee and such heirs, personal
representatives, executors and administrators after Indemnitee has ceased to
have Corporate Status.

         16. Subrogation. In the event of any payment of Indemnifiable Amounts
under this Agreement, the Company shall be subrogated to the extent of such
payment to all of the rights of contribution or recovery of Indemnitee against
other persons, and Indemnitee shall take, at the request of the Company, all
reasonable action necessary to secure such rights, including the execution of
such documents as are necessary to enable the Company to bring suit to enforce
such rights.

         17. Change in Law. To the extent that a change in Delaware law (whether
by statute or judicial decision) shall permit broader indemnification or
advancement of expenses than is provided under the terms of the By-laws of the
Company and this Agreement, Indemnitee shall

                                       7
<PAGE>   8
be entitled to such broader indemnification and advancements, and this Agreement
shall be deemed to be amended to such extent.

         18. Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such a manner as to be effective and valid under
applicable law, but if any provision of this Agreement, or any clause thereof,
shall be determined by a court of competent jurisdiction to be illegal, invalid
or unenforceable, in whole or in part, such provision or clause shall be limited
or modified in its application to the minimum extent necessary to make such
provision or clause valid, legal and enforceable, and the remaining provisions
and clauses of this Agreement shall remain fully enforceable and binding on the
parties.

         19. Indemnitee as Plaintiff. Except as provided in Section 10(c) of
this Agreement and in the next sentence, Indemnitee shall not be entitled to
payment of Indemnifiable Amounts or advancement of Indemnifiable Expenses with
respect to any Proceeding brought by Indemnitee against the Company, any Entity
which it controls, any director or officer thereof, or any third party, unless
such Company has consented to the initiation of such Proceeding. This Section
shall not apply to counterclaims or affirmative defenses asserted by Indemnitee
in an action brought against Indemnitee.

         20. Modifications and Waiver. Except as provided in Section 17 above
with respect to changes in Delaware law which broaden the right of Indemnitee to
be indemnified by the Company, no supplement, modification or amendment of this
Agreement shall be binding unless executed in writing by each of the parties
hereto. No waiver of any of the provisions of this Agreement shall be deemed or
shall constitute a waiver of any other provisions of this Agreement (whether or
not similar), nor shall such waiver constitute a continuing waiver.

         21. General Notices. All notices, requests, demands and other
communications hereunder shall be in writing and shall be deemed to have been
duly given (a) when delivered by hand, (b) when transmitted by facsimile and
receipt is acknowledged, or (c) if mailed by certified or registered mail with
postage prepaid, on the third business day after the date on which it is so

         22. Governing Law. This Agreement shall be governed by and construed
and enforced under the laws of Delaware without giving effect to the provisions
thereof relating to conflicts of law.

         23. Consent to Jurisdiction. The Company hereby irrevocably and
unconditionally consents to the jurisdiction of the courts of the State of
Delaware and the United States District Court for the District of Delaware. The
Company hereby irrevocably and unconditionally waives any objection to the
laying of venue of any Proceeding arising out of or relating to this Agreement
in the courts of the State of Delaware or the United States District Court for
the District of Delaware, and hereby irrevocably and unconditionally waives and
agrees not to plead or claim that any such Proceeding brought in any such court
has been brought in an inconvenient forum.
