                                     PART I

ITEM 1.  DESCRIPTION OF BUSINESS

GENERAL 

         Marcum Natural Gas Services, Inc. (the "Company" or "Marcum") is a
diversified provider of energy measurement products, services and data
management to the energy industry. The Company, incorporated in Delaware on
April 5, 1991, is a holding company that conducts its continuing operations
through two directly owned subsidiaries:

         o        Metretek, Incorporated ("Metretek"), which is engaged in the
                  design, manufacture and distribution of automated energy
                  consumption monitoring and recording systems; and

         o        Southern Flow Companies, Inc. ("Southern Flow"), which is
                  engaged in the provision of natural gas measurement services
                  and related equipment.

         References to the "Company" or "Marcum" in this Report on Form 10-KSB
mean Marcum Natural Gas Services, Inc. and its subsidiaries, unless the context
indicates otherwise.

         Metretek, based in Melbourne, Florida, 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, based in
Lafayette, Louisiana, provides a wide variety of natural gas measurement
services principally to producers and operators of natural gas production
facilities.

         During 1998, the Company decided to discontinue the operations of
Marcum Gas Transmission, Inc. ("MGT"), a directly owned subsidiary of the
Company that was formed 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. This decision was based on the declining
prospects of the markets and in order to enable the Company to focus on its
Southern Flow and Metretek 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 those programs are
sold or the programs are liquidated.

         Until 1997, the Company had also operated in the compressed natural gas
("CNG") industry through Marcum Denver, Inc. (formerly named Marcum Fuel
Systems, Inc.) ("Marcum Denver"), a directly owned subsidiary of the Company
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.

         In March 1999, the Board of Directors of the Company adopted a
resolution authorizing an amendment to the Company's Restated Certificate of
Incorporation, as amended, to change the name of the Company to "Metretek
Technologies, Inc." The change of the Company's name is subject to approval by
the stockholders of the Company. The Board of Directors intends to include the
proposal to change the Company's name in the Proxy Statement for the Annual
Meeting of Stockholders currently scheduled to be held on June 7, 1999.

BUSINESS STRATEGY

         The Company's business strategy is to position itself as an integrated
provider of data management products and services which enhance the flow of
information to the energy industry. To date, the Company's 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. The Company intends to provide
its products and services to other segments of the energy industry. The energy
industry generally is undergoing fundamental regulatory and structural changes
and trends. The Company's strategy is to acquire, develop and operate businesses
that are positioned to take advantage of these trends.

         In implementing its business strategy, the Company has made several
acquisitions. In 1993, the Company acquired substantially all of the assets of
the Southern Flow Companies division of Weatherford International Incorporated
("Weatherford"), a provider of natural gas measurement services. In 1994, the
Company acquired Metretek. In May 1998, the Company acquired substantially all
of the assets and business of American Meter Software Corporation (formerly
Eagle Research Corporation) ("American Meter Software"), a subsidiary of
American Meter Company ("American Meter"). While the Company regularly engages
in discussions relating to potential acquisitions and dispositions, the Company
has no present agreements or commitments with respect to any material
acquisition or disposition.

METRETEK, INCORPORATED

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

         Products. Metretek's manufactured products fall into three categories:
remote data collection products; electronic corrector products; and
application-specific products. Within these categories, Metretek'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 proprietary database consisting of a software system running on a
centrally located personal computer or 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 certain assets from
American Meter in May 1998, Metretek offers a complete line of natural gas
volume electronic corrector products. These corrector products include all or
some of the following functions:

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

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

         o        Full remote data collection capabilities;

         o        Users definable alarm detection and fault limits;

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

         o        Automatic self-calibration features;

         o        Compatibility with numerous volumetric meters; and

         o        Capability of providing corrector features for multiple meters
                  simultaneously.

         In addition to the two primary product lines referred to above,
Metretek 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 also
provides certain services to its customers. Metretek offers post-sale support
services which help create and maintain customer satisfaction and loyalty.
Metretek has recently commenced offering "energy data collection and management
services" under the trade name "TotalPlan" for customers who are unable or
unwilling to make the investment required to own a Metretek system. In this
turn-key service, Metretek 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 penetrate
the commercial account AMR markets.

         In 1997, Metretek commenced offering contract manufacturing of
electronic circuit boards by acquiring Sigma VI, Inc. ("Sigma VI"). Metretek
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 made these acquisitions to gain control of the
quality and timeliness of Metretek's manufactured circuit boards and
subassemblies and to optimize labor hours expended in the Metretek manufacturing
operation. With the automated equipment and experienced personnel acquired,
Metretek is able to offer contract manufacturing to local electronics
manufacturers who have high quality, short run, quick turnaround requirements.


                                       6

         A critical element of Metretek's product line is its data collection
and management capability. With the exception of the Sigma VI products,
virtually all of Metretek's products are integrated with Metretek's database
software package, the DC 2000 system. This system provides substantial
flexibility for 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 Software product line, Metretek and American Meter are
working towards the cross-functionality of certain of their products in an 
effort to enhance data management by Metretek's customers.

         Markets. Historically, Metretek'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 systems
to monitor and record the natural gas consumption of their industrial and
commercial accounts. The timely and accurate information provided by the
Metretek system is used by the operations, engineering, natural gas supply,
marketing, customer service and billing departments of the LDC. In the future,
Metretek 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:

         o        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;

         o        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

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

         Historically, Metretek has been the leading provider of AMRs to the
industrial natural gas market, which is becoming saturated. The primary target
for Metretek's AMR products is the recently developing commercial natural gas
user market, Metretek 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 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 also
provides implementation services for its customers designed to meet its
customer's specific needs. Metretek 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's marketing strategy includes utilizing
its close contacts with the utility industry through its sales representatives.
Metretek also participates in 



                                       7
<PAGE>   8

trade shows, symposiums and conferences designed to expand industry awareness of
its products. Metretek also utilizes direct mailing of brochures and
newsletters, and has a home page on the internet.

         International. Outside of North America, Metretek 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 18% to 21% of Metretek'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 systems. Metretek Europe Limited
("Metretek Europe"), a wholly owned subsidiary of Metretek located in Camberley,
England, sells Metretek products primarily in Western Europe.

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

         On May 4, 1998, Metretek acquired substantially all of the assets and
business of American Meter Software pertaining to electronic correctors and
non-radio-frequency meter reading devices in the natural gas and electric
utility industry. American Meter Software is a wholly owned subsidiary of
American Meter, which is ultimately controlled by Ruhrgas AG, a German
corporation. 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, and a $1,200,000 convertible
subordinated promissory note ($600,000 of which is contingent upon Metretek
exceeding certain sales targets, as discussed below) (the "American Meter
Note"). The purchase price is subject to upward adjustment based upon Metretek's
actual sales of products in the acquired business during the 18-month period
that commenced July 1, 1998. If Metretek's annualized sales of products in the
business acquired are greater than $3,900,000 during such period, then the
purchase price will be increased on a dollar-for-dollar basis to the extent of
such sales surplus, but the purchase price shall not be increased above
$4,500,000 even if annualized sales are greater than that amount. Any increase
in the purchase price will be effected by adjusting the principal balance of the
American Meter Note. Subsequent to the 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.

         Up to $1,028,107 of the American Meter Note is convertible at any time
at the option of American Meter Software into 180,766 shares of Common Stock of
the Company at the rate of $5.6875 of principal per share. The American Meter
Note bears interest on the unpaid principal balance at a fixed rate equal to
7.5% per annum, payable quarterly in arrears. The American Meter Note is due and
payable May 4, 2002, and may be prepaid at any time without penalty or premium.
The Company granted American Meter Software the one-time option to cause the
shares of Common Stock issued to American Meter Software at the closing or
issuable upon conversion of the American Meter Note to be registered under the
Securities Act of 1933, as amended, and applicable state securities laws, and
has 


                                       8
<PAGE>   9


also granted Eagle certain piggy-back registration rights to include such shares
in any registration statement filed by the Company, subject to customary
underwriter cutbacks.

         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 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 products in the United States and Canada at certain agreed-upon
prices. American Meter and American Meter Software have 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 (5) years from the closing date. In
connection with this acquisition, Harry I. Skilton, President of American Meter,
became a member of the Board of Directors of the Company. See "Item 9.
Directors, Executive Officers, Promoters and Control Persons; Compliance with
Section 16(a) of the Exchange Act".

         On June 15, 1998, Metretek acquired substantially all of the assets of
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.

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. The Company commenced its operations in this line
of business in 1991 by acquiring an existing business. This business was
expanded significantly in 1993 when the Company 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" 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 


                                       9
<PAGE>   10

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. The Company believes that it is able to effectively compete by (i)
providing dependable integrated measurement services, (ii) maintaining local
offices in proximity to its customer base, and (iii) retaining experienced and
competent personnel.

COMPETITION

         The Company competes in various markets pertaining to data management
products and services for the energy industry, in primarily the natural gas
industry. These markets are highly competitive, subject to rapid technological
change and significantly affected by new product introductions. There can be no
assurance that the Company will be able to compete successfully against current
and future competitors, and any failure to do so would have a material adverse
effect on the Company's business, financial condition, results of operations and
cash flow.

         The Company believes that the following are the principal competitive
factors affecting the market for its products and services:

         o        Responsiveness to customers' needs;

         o        Functionality;

         o        Speed of implementation;

         o        Ease of use;

         o        Performance and features;

         o        Quality and reliability;

         o        Reputation;

         o        Quality of customer support; and

         o        Price.

         The Company believes that it competes favorably with respect to the
above factors, although with respect to products and services that the Company
does not believe price is a principal competitive factor, the Company does not
compete on the basis of price. In order to be successful in the future, the
Company must continue to respond promptly and effectively to the challenges of
technological change and its competitors' innovations. The Company cannot
guarantee that its products and services will continue to compete favorably or
that it will be successful in facing the increasing competition for new 


                                       10
<PAGE>   11


products and enhancements introduced by its existing competitors or new
competition entering the market.

         The market for Metretek's products and services is very competitive.
Although Metretek'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. The Company believes 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 is currently or is intending to compete. Most of Metretek's
present and potential competitors have substantially greater financial,
marketing, technical and manufacturing resources, as well as greater name
recognition and experience, than Metretek. Metretek competes with a large number
of existing and potential competitors in these markets, some of which do not
compete in all of the same markets as Metretek. 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's prospective customers. Metretek 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.

REGULATION

         Regulation of Natural Gas Industry Generally. The Company's 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.

         The Company's international operations are also subject to the
political, economic and other uncertainties of doing business abroad including,
among others, risks of war, cancellation, 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 the Company conducts, plans to conduct
or in the future may conduct operations.



                                       11
<PAGE>   12


         Federal and State Regulation of Natural Gas. Natural gas sales have
been deregulated at the wholesale, or pipeline, level since Federal Energy
Regulatory Commission ("FERC") 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, the Company believes 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. The Company believes that Metretek
will benefit from such a regulatory environment.

         Environmental Regulation. 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 the
Company's operations as a result of their effect on natural gas development,
exploration, production, transportation and dispensing operations, the Company's
operations are not currently subject to substantial environmental laws and
regulations. The Company believes it is in material compliance with those
environmental laws and regulations to which it is subject. It is not anticipated
that the Company will be required in the near future to expend amounts that are
material in relation to its total capital expenditures program by reason of
environmental laws and regulations. However, inasmuch as such laws and
regulations are frequently changed, the Company is unable to predict the
ultimate effect on the Company and cost of compliance to the Company.

EMPLOYEES

         At February 28, 1999, the Company and its subsidiaries had 259
full-time employees. None of the Company's employees are covered by a collective
bargaining agreement. The Company believes that its relations with its employees
are good.

RESEARCH AND DEVELOPMENT

         The Company's basic research and development activities are conducted
by Metretek. Metretek 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 the
Company'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). The Company incurred $961,383 and
$1,062,264 for research and development expenses during the years ended December
31, 1998 and 1997 respectively. The Company intends to continue to allocate
resources to the research and development of new Metretek products and services
in the future. The Company's future services will depend, in part, on its
services in these development projects which will require continual substantial
investments.

RAW MATERIALS

         The Company's 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


                                       12
<PAGE>   13


supplier of materials would not have a material adverse impact on the business
or operations of the Company, shortages in certain components such as memory
chips, supply problems from the Company's suppliers or the Company's inability
to develop alternative sources of supply quickly or cost-effectively could
materially impact the Company's ability to manufacture its products and
therefore could adversely affect the Company's business and operations. The
Company attempts to mitigate this risk by maintaining an inventory of such
materials.

PROPRIETARY RIGHTS

         The Company's success and ability to compete are dependent in part upon
its proprietary rights and technology. The Company relies on a combination of
patents, copyrights, trademarks and trade secret laws to establish and protect
its rights in its products and proprietary technology. Although the Company
maintains certain patents related to its business, the Company does not believe
that its competitive position is dependent upon patent protection or that its
operations are dependent upon any individual patent. Nevertheless, the Company
believes that the following factors are more essential to protecting its
technology leadership position:

         o        The technological and creative skills of the Company's
                  personnel;

         o        New products and service development;

         o        Frequent product and service enhancements;

         o        Name recognition;

         o        Customer training and support; and

         o        Reliable product support.

         The Company generally requires its 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 the Company's means of protecting its proprietary rights in the U.S. or
abroad will be adequate. In addition, the laws of some foreign countries may not
protect the Company's proprietary rights as fully or in the same manner as do 
the laws in the United States. Despite the Company's efforts to protect its
proprietary rights, it may be possible for unauthorized third parties to copy,
reverse engineer or otherwise obtain, use or exploit aspects of the Company's
products, develop similar technology independently or otherwise obtain and use
information that the Company regards as proprietary. There can be no assurance
that the Company's competitors will not independently develop technologies
similar or superior to the Company's technology or design around the proprietary
rights owned by the Company. Although the Company is not aware that its products
infringe on the proprietary rights of third parties, there can be no assurance
that others will not assert claims of infringement in the future or that, if
made, such claims will not be successful.

ADDITIONAL FACTORS THAT MAY AFFECT THE COMPANY'S FUTURE RESULTS

         In addition to other information in this Annual Report on Form 10-KSB,
the following factors should be carefully considered in evaluating the Company
and its business because such factors involve risks and uncertainties that may
have significant impact in the future of the Company's business, financial
condition and results of operations.


                                       13
<PAGE>   14


         THE COMPANY'S HISTORY OF NET LOSSES. Although the Company has reported
income from continuing operations in recent fiscal years and net income in
certain recent fiscal quarters, the Company has a history of incurring net
losses since it commenced operations in 1991. As of December 31, 1998, the
Company had an accumulated deficit of approximately $21.5 million. For the
fiscal years ended December 31, 1998 and 1997, the Company had net losses of
$339,316 and $1,524,137, respectively, although the Company had income from
continuing operations of $343,800 in 1997. Most of the Company's historical
operating losses were incurred by its CNG refueling station equipment business,
which was sold in 1997. There is no assurance that the Company will be able to
ever achieve or sustain profitability, and if the Company does achieve
profitability in any period, the Company may not be able to sustain or increase
profitability on a quarterly or annual basis.

         QUARTERLY FINANCIAL RESULTS ARE SUBJECT TO SIGNIFICANT FLUCTUATIONS.
The revenues and operating results of the Company have varied widely in the
past, and the Company expects that they will continue to vary significantly from
quarter to quarter in the future due to a number of factors, some of which are
outside of the Company's control, including the following:

         o        Demand for the Company's products and services;

         o        The size and timing of sales and orders;

         o        The level of product and price competition that the Company
                  encounters;

         o        The length of the Company's sales cycle;

         o        The timing of the Company's new product introductions and
                  enhancements and those of its competitors;

         o        Market acceptance of the Company's new products;

         o        Changes in the Company's pricing policies and those of its
                  competitors;

         o        Variations in the length of the Company's product
                  implementation process;

         o        The mix of products and services sold;

         o        The mix of international and domestic revenue;

         o        Changes in sales incentives;

         o        Lifecycles of Company's products;

         o        Expansion of international operations;

         o        The general economic and political conditions;

         o        Budgeting cycles of utilities;

         o        Delays in internal product design projects;


                                       14
<PAGE>   15


         o        Acceptance of new products and new technology in the Company's
                  markets;

         o        Shifting customer basis;

         o        Company's expenditures on research and development;

         o        Economic conditions in the utility industry;

         o        The effects of government regulations and regulatory changes;

         o        Capital expenditures and other costs relating to the expansion
                  of operations;

         o        Prices charged by suppliers; and

         o        Costs related to acquisitions of technology or businesses.

         Because many of the Company's operating expenses are relatively fixed,
a shortfall in anticipated revenue or delay in recognizing revenue could cause
operating results to vary significantly from quarter-to-quarter and could result
in operating losses. The timing of large individual sales is also difficult for
the Company to predict. In some cases, sales have occurred in quarters
subsequent to those anticipated by the Company. To the extent one or more of
such sales are lost or occur later than expected, operating results could be
materially adversely affected. If the Company's revenues fall below expectations
in any particular quarter, the Company's business, financial condition or
results of operations could be materially adversely affected. Because the
Company generally fills orders within three to six months of receipt, revenues
for each quarter depend on sales completed in that quarter or the prior quarter.
If revenues fall below expectations, the Company will not be able to reduce its
spending rapidly in response to such a shortfall.

         For reasons noted below, the Company may experience significant
seasonality and cyclicality with respect to its business. Poor weather
conditions during hurricane season can adversely affect revenues from Southern
Flow. Additionally, the natural gas utility industry is cyclical, with sales of
products to the natural gas utility industry affected by changes in the prior
winter's weather patterns. As a result of the unpredictability of the utility
sales cycles, increased uncertainty in the utility markets attributable to the
regulatory reforms referred to below, and strong competitive forces, the Company
does not have a precise basis to predict future revenues and operating results.

         Due to the foregoing factors, the Company believes that
quarter-to-quarter comparisons of its operating results are not a good
indication of future performance. It is likely that the Company's results of
operations in some future quarter may be below the expectations of public market
analysts or investors. In this event, the price of the Company's Common Stock is
likely to decline.

         DEPENDENCE ON UTILITY INDUSTRY AND UNCERTAINTY RESULTING FROM
REGULATORY REFORM. Metretek has historically derived substantially all of its
revenues from sales of its products and services to the utility industry.
Metretek 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 


                                       15
<PAGE>   16


cycles that can take up to several years to complete. Metretek'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'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.

         The domestic utility industry is currently the focus of regulatory
reform initiatives in virtually every state, which initiatives have resulted in
significant uncertainty for industry participants and raised concerns regarding
assets that would not be considered for recovery through ratepayer charges.
Consequently, many utilities are delaying purchasing decisions that involve
significant capital commitments. While Metretek expects some states will act on
these regulatory reform initiatives in the near term, there can be no assurance
that the current regulatory uncertainty will be resolved in the near future or
that the advent of new regulatory frameworks will not have a material adverse
effect on Metretek's business, financial condition or results of operations.
Moreover, in part as a result of the competitive pressures in the utility
industry arising from the regulatory reform process, many utility companies are
pursuing merger and acquisition strategies. Metretek has experienced
considerable delays in purchase decisions by utilities that have become parties
to merger or acquisition transactions. Typically, such purchase decisions are
put on hold indefinitely when merger negotiations begin. The pattern of merger
and acquisition activity among utilities may continue for the foreseeable
future. If such merger and acquisition activity continues at its current rate or
intensifies, the Company's results of operating may continue to be materially
adversely affected.

         NEED FOR ADDITIONAL FUNDS IN THE FUTURE. The Company anticipates that
it will have a continuing need for additional funds to accomplish its business
strategy in the future. In addition, unanticipated events, over which the
Company may have no control, could increase the Company's operating costs or
decrease its ability to generate revenues from product and service sales. The
Company anticipates, based on the Company's currently proposed plans and
assumptions relating to its existing operations, that projected cash flow from
operations and its available capacity under its current credit facility will be
sufficient to satisfy its anticipated cash requirements for existing operations
in 1999. However, the Company will require additional capital in the future in
order to make any significant acquisitions of businesses or technologies. In the
event the Company's plans change, its assumptions change or prove to be
inaccurate or if projected cash flow from operations prove to be insufficient to
fund operations (including for reasons related to unanticipated technical or
other problems), the Company could be required to seek additional financing.
There is no assurance that the Company will be able to raise needed funds on
terms satisfactory to it, or that sufficient funds will be available when needed
to pursue its business plan. In addition, the terms of the Company's existing
credit facility prohibits the Company from incurring additional indebtedness
without lender consent. The Company's inability to secure necessary funds to
finance its business operations at the times and in the amounts required could
have a material adverse effect on its business, financial condition and results
of operations.

         DEPENDENCE UPON AND UNCERTAINTY OF NEW PRODUCTS AND NEW TECHNOLOGIES.
The Company has made and expects to continue to make substantial investments in
technology relating primarily to Metretek's business. The success of the
Company, particularly with respect to Metretek, depends to a significant extent
on the development and implementation of new product designs and technologies,
as well as the enhancement of its existing products. This product development
will require additional 


                                       16
<PAGE>   17

investments in order to maintain and enhance the Company's market position.
There can be no assurance that unforeseen problems will not occur with respect
to the Company's technology or products. Development schedules for new products
are subject to uncertainty and there can be no assurance that the Company will
meet its product development schedule. The Company has experienced delays in new
product development in the past and there can be no assurance that delays will
not be experienced in the future. Delays in new product development can result
from a number of causes, including changes in definition during the development
stage, initial failures of products or unexpected behavior of products under
certain conditions, failure of third-party supplied components to meet
specifications or lack of availability of such components, unplanned
interruptions with existing products that can result in reassignment of product
development resources, and other factors. Delays in the development and
availability of new products could have a material adverse effect on the
Company's business and operations. In addition, the Company's business may be
substantially adversely impacted if the Company is unable to keep abreast of the
latest technological developments, if the Company's existing technologies are
rendered obsolete or uneconomical, if the regulations or standards that are
developed are not favorable to the Company's product lines or the Company's
competitors obtain more favorable market acceptance. There can be no assurance
that the Company will be successful in developing new products or enhancing its
existing products on a timely or cost-effective basis, or that such new products
or product enhancements will achieve market acceptance.

         Also, the Company's ability to compete in new markets will depend upon
a number of factors including, without limitation the following:

         o        The Company's ability to create demand for its products in
                  such markets;

         o        The Company's ability to manage its growth effectively;

         o        The quality of its products;

         o        The Company's ability to respond to changes in its customers
                  businesses by updating existing products and introducing, in a
                  timely fashion, products which meet the needs of its
                  customers; and

         o        The ability of the Company to respond rapidly to technological
                  change.

         The failure of the Company to do any of the foregoing could result in a
material adverse effect on its business, financial condition and results of
operations. No assurance can be given that the Company will be able to
successfully compete in these markets, or that it will be able to meet the
technical specifications imposed by its customers or potential customers.

         RISKS DUE TO CHANGING PRODUCT MIX. The gross margin on the Company's
revenues from some of its product and service lines is higher than the gross
margin on other of its product and service offerings. Accordingly, any change in
the mix of types of products and services sold towards lower margin products and
services will affect the gross margin on the Company's total revenues and,
accordingly, will result in lower net income (or higher net losses) on the same
amount of revenues. A change in product and service mix resulting in lower gross
margin could have a material adverse effect on the Company's business, financial
condition, results of operations and cash flow.

         RISKS OF MANAGING PRIVATE PROGRAMS. Although the operations of MGT have
been discontinued and MGT does not intend to form any new private programs, MGT
will remain in the 


                                       17
<PAGE>   18

business of managing two business trusts that operate natural gas asset programs
until MGT's interests in those business trusts are sold or the programs are
liquidated. These private programs were financed by private placements of equity
interests raising capital to acquire the assets and business operated by the
programs. Management of such private energy programs involves certain risks
including, but not limited to:

         o        Risks due to adverse changes in the success of the programs
                  due to events, conditions and factors outside of the control
                  of MGT, such as general and local conditions affecting the
                  energy market and the price of the program's products;

         o        Changes in the regulatory environment;

         o        Reliance upon suppliers and customers;

         o        Hazards of energy facilities; and

         o        Changes in technology.

         RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS. The Company,
principally through Metretek, markets and sells its products and services in
certain international markets. Metretek has an established office in the United
Kingdom. International revenues, which are comprised of export sales to foreign
markets from the United States and sales by Metretek's United Kingdom
subsidiary, constituted approximately 8% and 9% of the Company's consolidated
revenues in fiscal years 1998 and 1997, respectively. The Company, primarily
through Metretek, intends to continue and expand its international operations
and enter new international markets. This expansion will require significant
management attention and financial resources. Additionally, costs associated
with international expansion include the establishment of additional offices,
hiring of additional personnel, localization and marketing of products and
services in foreign markets, and the development of relationships with
international service providers. If international revenue is not adequate to
offset the expense of expanding foreign operations, the Company's business,
financial condition and results of operations could be materially adversely
affected. The Company's international operations are also subject to other
inherent risks, including:

         o        Changes in applicable laws and regulatory requirements;

         o        Export and import restrictions;

         o        Export controls relating to technology;

         o        Tariffs and other trade barriers;

         o        Less favorable intellectual property laws;

         o        Difficulties in staffing and managing foreign operations;

         o        Political instability;

         o        Fluctuations in currency exchange rates;


                                       18
<PAGE>   19


         o        Potential adverse tax consequences;

         o        Cultural and language difficulties;

         o        The impact of a recessionary environment in economics outside
                  the United States;

         o        The potential exchange and repatriation of foreign earnings;

         o        Localization and translation of products;

         o        Difficulties in collecting accounts receivable and longer
                  collection periods; and

         o        The impact of local economic conditions and practices.

         The Company's success in expanding its international operations
depends, in part, on its ability to anticipate and effectively manage these and
other risks. The Company has limited experience in conducting its business
outside the United States and may encounter unforeseen difficulties in
conducting operations in foreign countries. In addition, while the Company's
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 the Company's ability to conduct
business in such markets. In addition, the Company may confront significant
challenges in developing and implementing localized versions of its system due
to many factors including the differing standards among utilities on a country
by country basis.

         A portion of the Company's revenues from sales to foreign entities is
in the form of foreign currencies. The Company has no hedging or similar foreign
currency contracts, and fluctuations in the value of foreign currencies could
adversely impact the profitability of the Company's foreign operations. There
can be no assurance that one or more of such factors will not have a material
adverse effect on the Company's future international activities and,
consequently, on the Company's business, financial condition or results of
operations.

         COMPETITION. The markets for the Company's products and services are
highly competitive and are characterized by rapidly changing technology,
frequent product and service performance improvements and evolving industry
standards. The Company believes that its future ability to compete effectively
will depend, in part, upon its ability to continue to improve its products and
services and process technologies and to develop new technologies in order to
maintain the performance advantages of products and processes relative to
competitors, to adapt products and services and processes to technological
changes, to identify and adopt emerging industry standards and to adapt to
customer needs. Many of the Company's present and potential competitors have
substantially greater financial, marketing, technical, manufacturing and other
resources, name recognition and experience than the Company. The Company's
competitors may be able to respond more quickly to new or emerging technologies
and changes in customer requirements or to devote greater resources to the
development, promotion and sale of their products and services than the Company.
There can be no assurance that the Company will be able to compete successfully
in the future with any of these sources of competition. In addition, there can
be no assurance that competitive pressures will not result in price erosion,
reduced margins, loss of market share or other factors. Any of the foregoing
could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Competition" above.



                                       19
<PAGE>   20


         DEPENDENCE UPON FUTURE ACQUISITIONS. Acquisitions have in the past
played an important role in implementing the Company's business strategy. The
Company believes that additional acquisitions in the future are important to its
growth, development and continued ability to compete effectively in the
marketplace. The Company evaluates potential acquisitions and strategic
investments on an ongoing basis. In the event the Company were to identify an
appropriate acquisition candidate, there is no assurance that the Company would
be able to successfully negotiate the terms of any such acquisition, finance
such acquisition and integrate such acquired business, products, technologies or
services into the Company's existing business and operations. Furthermore, the
integration of an acquired business could cause a diversion of management time
and resources. In addition, there can be no assurance that any acquisition of
new technology will lead to the successful development of new products, or that
any such new products or services, if developed, will achieve market acceptance
or prove to be profitable. There can be no assurance that a given acquisition,
when consummated, would not materially adversely affect the Company's business,
financial condition or results of operations. If the Company proceeds with one
or more significant acquisitions in which the consideration consists of cash, a
substantial portion of the Company's available cash could be used to consummate
the acquisitions and may result in increased indebtedness, interest and
amortization expense or decreased operating income (or increased operating
losses), any of which could have a material adverse effect on the Company's
business, financial condition and results of operations. If the Company
consummates one or more significant acquisitions in which the consideration
consists of capital stock or securities convertible into capital stock, or is
financed with the net proceeds of the issuance of capital stock or securities
convertible into capital stock, stockholders of the Company could suffer a
significant dilution of their percentage ownership interests in the Company.
Except as otherwise set forth herein, the Company presently has no agreements or
commitments with respect to any material acquisition and there can be no
assurance that any such additional businesses will be acquired. In addition,
there can be no assurance that any such acquisitions, if made, will be
successful or that they will assist the Company in the accomplishment of its
long-term business strategy.

         UNCERTAINTY OF PROTECTION OF INTELLECTUAL PROPERTY AND PROPRIETARY
RIGHTS AND INFRINGEMENT RISKS. The Company's success and ability to compete are
dependent in part upon its intellectual property and proprietary rights and
technology. The Company relies on a combination of patents, copyrights,
trademark and trade secret laws, and confidentiality agreements and licensing
arrangements, to establish and protect its rights in its products and
proprietary technology. Although the Company maintains certain patents related
to its business, the Company does not believe that its competitive position is
dependent upon patent protection or that its operations are dependent upon any
individual patent. The Company generally requires its 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 the Company's means of protecting its proprietary rights will be
adequate. In addition, the laws of some foreign countries may not protect the
Company's proprietary rights as fully or in the same manner as do the laws of
the United States.

         Despite the Company's efforts to protect its proprietary rights, it may
be possible for unauthorized third parties to copy, reverse engineer or
otherwise obtain, use or exploit aspects of the Company's products, develop
similar technology independently, or otherwise obtain and use information that
the Company regards as proprietary. There can be no assurance that the Company's
competitors will not independently develop technologies similar or superior to
the Company's technology or design around the proprietary rights owned by the
Company. In addition, the Company may resort to litigation to enforce its
intellectual property rights, to protect its trade secrets, to determine the
validity and scope of others' proprietary rights, or to defend against claims of



                                       20
<PAGE>   21


infringement or invalidity in the future. Such litigation could result in
significant costs or the diversion of resources. This could materially adversely
affect the Company's business, financial condition or results of operations.

         The Company may receive notice of claims of infringement of other
parties' proprietary rights in the normal course of business. Although the
Company does not believe that its products infringe the proprietary rights of
third parties, the Company cannot guarantee that such infringement or invalidity
claims will not be asserted or prosecuted against the Company. Defending such
claims, regardless of their validity, could result in significant costs and
diversion of resources. Such assertions or defense of such claims may materially
adversely affect the Company's business, financial condition or results of
operations. In addition, such assertion could result in injunctions against the
Company. Injunctions that prevent the Company from distributing its products
would have a material adverse effect on its business, financial condition and
results of operations. If such claims are asserted against the Company, the
Company may seek to obtain a license to use such intellectual property rights.
There can be no assurance that such a license would be available on commercially
reasonable terms.

         UNCERTAINTY AND RISKS RESULTING FROM YEAR 2000 ISSUES. The "Year 2000
issue," which presents potential risks and uncertainties to virtually all
businesses, is the result of computer programs that use two digits rather than
four to define the applicable year. Any computer programs that have
time-sensitive software may recognize a date using "00" as the year 1900 rather
than the year 2000. This situation could result 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 normal business activities.

         The Company may be affected by Year 2000 issues related to
non-compliant information technology, systems or non-information technology
systems operated by the Company or by third parties. The Company has
substantially completed its evaluation and assessment of its internal and third
party information technology systems and non-information technology systems. At
this point in its assessment, the Company is not currently aware of any Year
2000 issues relating to systems operated by the Company or by third parties that
would have a material adverse effect on the Company's business, results of
operations or financial condition. The Company has and will continue to modify
and replace portions of its existing information technology system so they will
function properly with respect to dates in the Year 2000 and thereafter. Based
on its assessment to date, the Company does not anticipate that costs associated
with remediating the Company's non-compliant information technology or
non-information technology systems will be material, although there can be no
assurance to such effect.

         The Company believes that the greatest risks from Year 2000 issues will
result from the failure of third parties, with which the Company has material
relationships or on which the Company is materially dependent, to become Year
2000 compliant. Although the Company is not presently aware of any significant
vendor, supplier, service provider or customer that will have Year 2000 issues
material to the Company's operations, many businesses are resistant to providing
any written or binding assurances that they will be Year 2000 compliant. In
addition, the Company has no control over Year 2000 compliance programs by third
parties. Accordingly, the Company cannot provide any assurance that the systems
of its essential vendors, suppliers, service providers or customers will be Year
2000 compliant. The lack of Year 2000 compliance by such third parties could
have a material adverse impact on the Company's results of operations, financial
condition and business. It is difficult to predict with a high degree of
accuracy, and impossible to guaranty, what impact any Year 2000 issues will have
on the Company. The Company currently anticipates a minimum level of disruption,



                                       21
<PAGE>   22


inconveniences and inefficiencies in its operations as a result of systems
failures, primarily related to non-compliance by third parties. The Company
believes the risks are greatest with respect to electric power and water supply,
and telecommunications and transportation services. Outages of any of these
vital services and supplies could prevent the Company from performing its
services or impair its ability to perform its services. There can be no
assurance that Year 2000 issues will not be material to the Company, or that the
cost of interruptions with the systems of third parties will not have a material
adverse effect on the Company's business, financial condition or results of
operations.

         UNCERTAINTY OF LEGAL PROCEEDINGS. The Company and one of its
subsidiaries are defendants to a pending action filed in 1993 in Denver District
Court in which the plaintiff is seeking damages in the amount of approximately
$420,000 and punitive damages. The Company believes the allegations against it
are without merit, intends to contest such allegations vigorously, and has
asserted counterclaims against the defendant. In 1997, the Denver District Court
entered a summary judgment in favor of the Company, but the summary judgment was
reversed on February 18, 1999 by the Colorado Court of Appeals. The Company
intends to appeal the reversal of the summary judgment motion to the Colorado
Supreme Court. The Company is also from time to time involved in routine
litigation incidental to its business, although currently there are no other
pending, or to the knowledge of management, threatened material proceedings.
Based upon current information, the Company does not expect any such proceedings
to have a material adverse effect on the Company. However, the outcome of
litigation is inherently uncertain, and such litigation could, despite
management's current expectations, result in a material adverse effect on the
Company's business, financial condition or results of operation. See "Item 3.
Legal Proceedings."

         RISKS INHERENT IN NATURAL GAS OPERATIONS. Some of the Company's
operations are subject to the hazards and risks inherent in the servicing and
operation of natural gas assets, including encountering unexpected pressures,
explosions, fire, natural disasters, blow-outs, cratering and pipeline ruptures,
which could result in personal injuries, loss of life, environmental damage and
other damage to the properties of the Company and 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 the Company. The Company has product liability
insurance generally providing up to $6,000,000 of coverage per occurrence and
$7,000,000 annual aggregate coverage. Although the Company believes that its
insurance is adequate and customary for companies of a similar size engaged in
operations similar to that of the Company, losses could occur for uninsurable or
uninsured risks or losses could occur in excess of existing injury coverage. The
occurrence of a significant adverse event, the risks of which are not fully
covered by insurance, could have a material adverse effect on the Company's
business, financial condition or results of operations. Moreover, the Company
cannot provide any assurance that it will be able to maintain adequate insurance
in the future at rates it considers reasonable.

         GOVERNMENTAL REGULATION. The Company's business operations are subject
to extensive federal, state, local and foreign laws and regulations. The Company
cannot provide any assurance that that laws and regulations either existing or
enacted in the future or the repeal or modification of current laws and
regulations will not adversely affect the Company's business, financial
condition or results of operations. Furthermore, amendments to statutes and
regulations and the Company's expansion into new areas could require the Company
to continually modify or alter methods of operations at costs which could be
substantial. There can be no assurance that the Company will be able, for
financial or other reasons, to comply with all applicable laws and regulations.
If the Company fails to comply with such laws, rules and regulations, then it
could be the subject of substantial penalties.


                                       22
<PAGE>   23



         DEPENDENCE ON KEY PERSONNEL. The Company's success depends to a large
extent on its ability to attract and retain highly qualified technical,
managerial, sales and marketing personnel, including the abilities and continued
participation of its executive officers and key employees. Competition for such
personnel is intense, and there can be no assurance that the Company will be
successful in hiring or retaining the requisite personnel in the future. The
Company does not carry key-man insurance policies on any of its officers,
directors or key employees. The loss of the services of any of these persons, or
the inability of the Company to hire qualified personnel on a timely basis and
retain their services, could have a material adverse effect on the Company's
business, financial condition or results of operations.

         DEPENDENCE ON BUSINESS RELATIONSHIPS TO ACHIEVE MARKET PENETRATION. A
key element of the Company's business strategy is the formation of corporate
relationships with other companies to provide products and services to existing
and new markets. The Company is currently investing, and plans to continue to
invest, significant resources to develop these relationships. The Company
believes that its success in penetrating new markets will depend in large part
on its ability to maintain these relationships and to cultivate additional or
alternative relationships. There can be no assurance that the Company will be
able to develop additional corporate relationships with such companies, that
existing relationships will continue or be successful in achieving their
purposes or that such companies will not form competing arrangements.

         CONTROL BY EXISTING STOCKHOLDERS. As of February 28, 1999, the
officers, directors and 5% or greater shareholders of the Company beneficially
owned approximately 1,612,849 shares of Common Stock (including shares issuable
upon the exercise or conversion of (i) presently exercisable stock options, (ii)
presently exercisable warrants, and (iii) the American Meter Note), which shares
constituted 40.1% of the total outstanding shares of Common Stock, assuming all
options, warrants and rights held by such persons are exercised or converted.
While the Company is unaware of any agreement among such persons to act
together, they would be able to materially influence and may effectively control
the outcome of all matters submitted to a vote of the Company's stockholders,
including (i) the election or removal of directors, and (ii) any merger,
consolidation or sale of all or substantially all of the assets of the Company.
Such a concentration of ownership may also have an adverse effect on the market
price of the Common Stock.

         SHARES ELIGIBLE FOR FUTURE SALE. Virtually all of the Company's
outstanding shares of Common Stock are presently eligible for immediate sale in
the public market. Sales of substantial amounts of Common Stock into the public
market, or a perception that such sales could occur, and the existence of
options and warrants to purchase Common Stock representing an overhanging
obligation of the Company to sell additional Common Stock at prices that may be
below the then current market price of the Common Stock, could adversely affect
the market price of the Common Stock and could impair the Company's future
ability to raise the capital through the sale of its equity securities. Also, as
of February 28, 1999, options to purchase 423,298 shares of Common Stock and
warrants to purchase 983,062 shares of Common Stock were outstanding. American
Meter has certain registration rights with respect to 620,326 shares of Common
Stock issued to it by the Company or issuable to it upon the conversion of the
American Meter Note.

         ANTI-TAKEOVER PROVISIONS. Certain provisions of (i) the Company's 
Restated Certificate of Incorporation, as amended (the "Certificate"), and the
Company's Amended and Restated By-Laws (the "By-Laws"), including a fair price
requirement, a classified Board of Directors, anti-greenmail restrictions,
super-majority vote requirements for certain fundamental corporate actions and
certain provisions relating to stockholder actions, (ii) the termination and
changes in control arrangements in the employment 


                                       23
<PAGE>   24


contracts with certain executive officers of the Company, and (iii) the
Company's Rights Agreement, may have the effect of delaying or preventing a
change in control of the Company and may make more difficult the removal of
incumbent management even if such transactions could be beneficial to
stockholders. Further, Section 203 of the General Corporation Law of the State
of Delaware (the "DGCL") prohibits the Company from engaging in certain business
combinations with interested stockholders. These provisions could have the
effect of delaying or preventing a change in control of the Company without
action by the stockholders, and therefore could adversely affect the market
price of Common Stock.

         AUTHORIZATION AND ISSUANCE OF PREFERRED STOCK. The Board of Directors
of the Company is authorized to issue, without further stockholder approval, up
to 2,500,000 shares of Preferred Stock, par value $.01 per share (the "Preferred
Stock"), which consists of 1,000,000 shares of Series A Preferred Stock,
1,000,000 shares of Series B Preferred Stock and 500,000 shares of Series C
Preferred Stock. The terms of the Series A Preferred Stock and the Series C
Preferred Stock are fixed and include rights preferential to the Common Stock
with respect to dividends and liquidation preferences. The Board of Directors is
also authorized to establish the dividend rates, liquidation preferences, voting
rights, redemption and conversion terms and privileges with respect to the
Series B Preferred Stock without further stockholder approval. The Company may
in the future issue shares of Preferred Stock or create additional series and
classification of Preferred Stock. No shares of Preferred Stock are currently
issued and outstanding, and the Company has no current plan or intention to
issue any shares of Preferred Stock. The issuance of any shares of Preferred
Stock having rights superior to those of the Common Stock may result in a
decrease in the value or market price of the Common Stock and, further, could be
used by the Board of Directors as a means to prevent a change in control of the
Company.

         NO DIVIDENDS. The Company has never declared or paid any cash dividends
on its Common Stock. The Company currently intends to retain its earnings, if
any, in the foreseeable future in order to finance the operations and growth of
the Company. In addition, the Company's credit facility prohibits the payment of
cash dividends without the consent of the lender. Accordingly, the Company does
not anticipate paying dividends to holders of Common Stock in the foreseeable
future.

         VOLATILITY OF COMMON STOCK PRICE. The market price of the Company's
Common Stock has in the past been, and in the future is likely to continue to
be, highly volatile. A variety of events could result in wide fluctuations in
the market price of the Common Stock, including without limitation:

         o        Quarter-to-quarter variations in operating results;

         o        News announcements;

         o        Trading volume;

         o        General trends in the industry;

         o        Overall market conditions;

         o        Technological innovations or new products or services by the
                  Company or its competitors;

         o        Revised earnings estimates or other comments by analysts; and


                                       24
<PAGE>   25



         o        General stock market trends and conditions.

         In addition, it is possible that in some future period the Company's
operating results may be below the expectations of public market analysts and
investors. In such event, the price of the Company's Common Stock could be
materially adversely affected. Additionally, the stock market in general, and
the market for technology and energy stocks in particular, have experienced
extreme price volatility in recent years. Volatility in price and volume has had
a substantial effect on the market prices of many technology and energy
companies for reasons unrelated or disproportionate to the operating performance
of such companies. These broad market fluctuations could have a significant
impact on the market price of the 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 instituted against such company. Such
litigation, if instituted, whether or not successful, could result in
substantial costs and diversion of management's attention and resources, which
would have a material adverse effect on the Company's business, results of 
operations and financial condition.

ITEM 2.  DESCRIPTION OF PROPERTY

         The Company leases its corporate executive offices located in downtown
Denver, Colorado, which contain 3,443 square feet. The lease currently has a
monthly rental obligation of $4,433, including operating costs, expires July 31,
2001, and contains a market-rate renewable lease provision.

         Metretek leases its principal business offices, located in Melbourne,
Florida, for its executive, manufacturing, engineering, warehouse and marketing
operations. This facility has 45,500 square feet and a current monthly rental
obligation of $29,420, including operating costs. The lease expires June 30,
2005. Metretek has sub-leased 8,470 square feet of its space for $7,053 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 57,000 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.

ITEM 3.  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 July 24, 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 judgement against the former employee's claims. On February 18,
1999, the Colorado Court of Appeals reversed the summary judgment. The Company
intends to appeal that ruling to the Colorado Supreme Court. The Company
believes the allegations against it and DVCO are without merit and intends to 



                                       25
<PAGE>   26
defend the action vigorously. Although the outcome of litigation is inherently
uncertain, 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.

         The Company is from time to time involved in routine litigation
incidental to its business. However, other than as set forth above, there are no
material legal proceedings currently pending, or to the knowledge of management,
threatened that the Company expects, based upon current information, to have a
material adverse effect on the business, financial condition or results of
operations of the Company.

ITEM 5.  MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

         The Company's Common Stock is traded on the Nasdaq National Market
under the symbol "MGAS". The Company's Common Stock Purchase Warrants (the
"Warrants") which were distributed as a special dividend to the Company's
stockholders on September 18, 1998 have traded on the Nasdaq SmallCap Market
since such date under the symbol "MGASW". The following table sets forth, for
the periods indicated, the closing high and low sales prices of the Common Stock
as reported on the Nasdaq National Market and of the Warrants as reported on the
Nasdaq SmallCap Market:

         Fourth Quarter .....      2.56      1.41      .75     .20
</TABLE>




         As of March 16, 1999, there were 308 holders of record of the Common
Stock and 324 holders of record of the Warrants. Because many of the shares of
Common Stock are held by brokers and other institutions on behalf of
stockholders, the Company is 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.

         The Company has never declared or paid any cash dividends on its Common
Stock. The Company's Board of Directors does not anticipate paying any cash
dividends in the foreseeable future, as it intends to retain any earnings to
finance the operations and growth of the Company. In addition, the Company's
credit facility prohibits the payment of dividends without the consent of the
lender. The payment of any cash dividends on the Common Stock in the future will
depend on such factors as the earnings, anticipated growth requirements and
operating and financial condition of the Company, contractual restrictions and
any other factors deemed relevant by the Board of Directors.

OF OPERATIONS

INTRODUCTION

         The following discussion of the results of operations for the Company
for the years ended December 31, 1998 and 1997 and of the consolidated financial
condition of the Company as of December 31, 1998 should be read in conjunction
with the Company's consolidated financial statements and related notes thereto
included elsewhere herein.

         In addition, this item contains certain forward-looking statements made
pursuant to the safe harbor provisions of Section 28A of the Securities Act and
Section 21E of the Exchange Act. Such forward-looking statements are subject to,
and are qualified by, risks and uncertainties that could cause actual results to
differ materially from those expressed or implied by those statements. These
risks and uncertainties include, but are not limited to, the factors described
under "Item 1. Description of Business -- Additional Factors That May Affect The
Company's Future Results" and other risks and uncertainties discussed in this
Item and elsewhere in this Form 10-KSB.

         The Company evaluates the performance of its 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 and income and expense not allocated to its operating segments.

         During 1998, the Company decided to discontinue its business segment
engaged in acquiring or financing the acquisition of natural gas assets through
private programs. In addition, on June 27, 1997, the Company sold its natural
gas refueling equipment segment and substantially all of the operating assets
related thereto. The financial statements have been reclassified to exclude the
operating results of these two segments from continuing operations and to
account for these segments as discontinued operations (see Note 3 to the
Consolidated Financial Statements). The following discussion relates only to the
Company's continuing operations.

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

         Revenues. The Company's consolidated revenues for the year ended
December 31, 1998 decreased $510,727, or 2%, compared to 1997, due principally
to a decrease in the revenues of Southern Flow. Southern Flow's revenues
decreased $479,625, or 4%, for the year ended December 31, 1998, compared to
1997 due to adverse weather conditions in the Gulf Coast during the third and
fourth quarters which limited Southern Flow's operating activities in its
principal operating region. Metretek's revenues for the year ended December 31,
1998 decreased $30,465, or less than 1%, compared to 1997, consisting of a
decrease in international sales of $222,874 and an increase in domestic sales of
$192,409. The decrease in Metretek's international revenues in 1998 was the net
result of the following key factors: (i) reduced sales to Metretek's customers
in South America; (ii) increased sales through Metretek Europe, its European
distribution subsidiary; and (iii) increased sales to Metretek's customers in
Australia and Canada. The increase in Metretek's domestic revenues in 1998 was
the net result of three key factors: (i) an improvement in circuit board
assembly sales by its wholly owned subsidiary, Sigma VI, due to the acquisition
of QCMI as well as the expansion of its line of business; (ii) electronic
corrector product sales occurring as a result of its acquisition of that product
line from American Meter Software in May 1998; and (iii) reduced sales of remote
data collection products due to decreased domestic demand for those products in
1998 compared to 1997.

         Costs and Expenses. Cost of sales and services include the product and
personnel and related overhead costs for the Company's goods and services. Cost
of sales and services for the year ended December 31, 1998 decreased $56,198, or
less than 1%, compared to 1997. Metretek's cost of sales and services for the
year ended December 31, 1998 decreased $89,480, or 2%, compared to 1997 due
primarily to decreased sales activity in 1998. Metretek's gross profit margin
after costs of sales and services for the year ended December 31, 1998,
increased from 51.2% to 52.1% compared to 1997. The improvement in Metretek's
gross profit margin reflected (i) cost reductions in electronic parts used in
its products; and (ii) a reduction in outsourcing costs to assemble the
electronic components of its products, which assembly is now being done
in-house. Metretek's gross profit margin is also dependent on its product mix
because the gross profit margin on some of its products and service lines is
higher than the gross profit margin on other of its products and services.
Changes in Metretek's product and service mix will affect Metretek's gross
profit margins in the future. Southern Flow's cost of sales and services for the
year ended December 31, 1998 increased $33,282, or less than 1%, compared to
1997, despite the overall decline in Southern Flow's revenues. Southern Flow's
gross profit margin after costs of sales and services for the year ended
December 31, 1998 decreased from 25.6% to 22.0% compared to 1997. Southern
Flow's gross profit margin declined because virtually all of its employee
service costs continued unabated during the periods when adverse weather
conditions reduced Southern Flow's revenues by limiting its service operations.


                                       29
<PAGE>   30


         General and administrative expenses include personnel and related
overhead costs for the support and administration functions of the Company.
General and administrative expenses for the year ended December 31, 1998
increased $124,237, or 4%, compared to 1997, due principally to the net effect
of the following factors: (i) a decrease in expenses of Metretek of
approximately $44,000 attributable to a reduction in personnel at Metretek
Europe as well as overall cost savings at Metretek and Sigma VI resulting from
combining certain administrative functions; (ii) a decrease in expenses of
Southern Flow of approximately $89,000 attributable to reduced personnel costs;
and (iii) an increase in general and corporate expenses of approximately
$257,000 due to increased professional services, travel and public company
reporting costs, as well as compensation costs associated with the Company's
1998 Employee Stock Purchase Plan for which there were no comparable costs in
1997.

         Selling, marketing and service expenses consist of personnel and
related overhead costs, including commissions for the sale and marketing
activities of the Company, together with advertising and promotion costs.
Selling, marketing and service expenses for the year ended December 31, 1998
decreased $117,597, or 7%, compared to 1997, substantially all of which related
to activities at Metretek. The decrease in these expenses was due to the
following factors: (i) fewer sales personnel during a significant portion of
1998 compared to 1997; (ii) reduced sales commissions due to fewer sales
personnel as well as a reduction in commission rates for certain sales
personnel; and (iii) reduced advertising and promotional expenses.

         Depreciation and amortization expenses include the depreciation and
amortization of the Company's real property, customer list, goodwill and
capitalized software development costs. Depreciation and amortization expenses
for the year ended December 31, 1998 increased $167,171, or 18%, compared to
1997. This increase was due to additional goodwill amortization costs related to
Metretek's recent acquisitions of the assets of American Meter Software and QCMI
as well as increased depreciation expenses at both Metretek and Southern Flow.

         Research and development expenses include personnel and related
overhead costs for product and service development, enhancements, and upgrades.
Research and development expenses for the year ended December 31, 1998 decreased
$100,881, or 9%, compared to 1997, due to reduced costs at Metretek of personnel
engaged in product enhancements and upgrade activities.

         Interest, finance charges and other expenses include interest and
finance charges on the Company's credit facility as well as other non-operating
expenses. Interest, finance charges and other expenses for the year ended
December 31, 1998 increased $121,773, or 191%, compared to 1997. The increase
reflects interest expense on additional borrowings in 1998 compared to 1997 in
order to fund Metretek's acquisitions of American Meter Software and QCMI,
borrowings to finance increases in Metretek's inventory and accounts receivable,
and the amortized portion of capitalized finance charges incurred in 1998 to
obtain the Company's current credit facility.

SEASONALITY AND CYCLICALITY

       Metretek historically derives substantially all of its revenues from
sales of its products and services to the utility industry. Metretek 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 


                                       30
<PAGE>   31


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'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'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 set forth in this item as well as the factors
set forth under "Item 1. Description of Business - Factors That May Affect the
Company's Future Results - - Quarterly Financial Results are Subject to
Significant Fluctuations", the Company believes that 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

         The Company requires capital principally for (i) the financing of
inventory and accounts receivable, (ii) research and development expenses, (iii)
capital expenditures for property and equipment and software development, and
(iv) the funding of possible future acquisitions.

         Net cash used by operating activities was approximately $1,460,000 for
the year ended December 31, 1998, which was the net result of the following: (i)
approximately $899,000 of cash provided by continuing operations, before changes
in operating assets and liabilities; (ii) approximately $2,356,000 of cash used
to fund changes in working capital and other asset and liability accounts; and
(iii) approximately $3,000 of cash used by discontinued operations.

         The Company plans to continue research and development efforts to
enhance its existing products and develop new products. The Company anticipates
that its research and development costs in 1999 will be approximately
$1,450,000, all of which will relate to Metretek's business. Research and
development expenses in the amount of $961,383 were incurred in the year ended
December 31, 1998.

         The Company anticipates capital expenditures in 1999 of approximately
$450,000, primarily for production and laboratory equipment, computer software
and hardware. Capital expenditures for the year ended December 31, 1998 totaled
$608,950.

         On May 4, 1998, Metretek acquired substantially all of the assets and
business of American Meter Software pertaining to electronic correctors and
non-radio-frequency meter reading devices in the natural gas and electric
utility industry. 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.


                                       31
<PAGE>   32


         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, and the $1,200,000
convertible subordinated American Meter Note ($600,000 of which is contingent
upon Metretek exceeding certain sales targets, as discussed below). The purchase
price is subject to upward adjustment based upon Metretek's actual sales of
products in the acquired business during the 18-month period that commenced July
1, 1998. If Metretek's annualized sales of products in the business acquired are
greater than $3,900,000 during such period, then the purchase price will be
increased on a dollar-for-dollar basis to the extent of such sales surplus, but
the purchase price shall not be increased above $4,500,000 even if annualized
sales are greater than that amount. Any increase in the purchase price will be
effected by adjusting the principal balance of the American Meter Note.
Subsequent to the 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.

         Up to $1,028,107 of the American Meter Note is convertible at any time
at the option of American Meter Software into 180,766 shares of Common Stock of
the Company at the rate of $5.6875 of principal per share. The American Meter
Note bears interest on the unpaid principal balance at a fixed rate equal to
7.5% per annum, payable quarterly in arrears. The American Meter Note is due and
payable May 4, 2002, and may be prepaid at any time without penalty or premium.

         On June 15, 1998, Metretek acquired substantially all of the assets of
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.

         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% (8.75% at December 31, 1998) 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,
inventory, 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 (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. Borrowings on
the 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 inventory
(up to a combined maximum of $1,500,000) of Southern Flow and Metretek.

         At December 31, 1998, the Company had a combined $4,375,458 Loan
availability, of which $2,561,702 had been borrowed by Southern Flow and
Metretek, leaving $1,813,756 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 


                                       32
<PAGE>   33


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.

         In September 1998, the Board of Directors of the Company adopted a
stock repurchase plan (the "Stock Repurchase Plan") pursuant to which the
Company is authorized to purchase up to approximately 7% of its outstanding
Common Stock in open market transactions, from time to time as management deems
appropriate, if the market price of the Company's stock remains below certain
levels. The Company may use the repurchased shares for employee benefit plans
and other corporate purposes, may hold the repurchased shares in treasury or may
retire the purchased shares. Through December 31, 1998, the Company had
repurchased 57,088 shares of its Common Stock at an average price of $2.25 per
share. In September 1998, prior to adopting the Stock Repurchase Plan, the
Company repurchased 18,181 shares of Common Stock that were issued to a licensor
pursuant to a license agreement in order to satisfy certain obligations of the
Company under the license agreement.

         Based on the Company's current plans and assumptions, management
believes that the Company's 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 its currently anticipated cash needs, including its working
capital needs, capital commitments and debt service requirements, for at least
the next twelve months. Additionally, the Company may also use a portion of its
capital resources to acquire businesses, products or technologies or to
repurchase its shares of Common Stock. However, the Company may require
additional funds to support its working capital requirements or for other
purposes. Depending upon the Company's financial condition, including its
liquidity needs and business activities, the conditions in the equity, debt and
other financial markets, as well as other factors, the Company may from time to
time seek to raise additional funds from the proceeds of public or private
equity financing, debt financing, the sale of assets or from other sources.
There can be no assurance that such additional funds will be available to the
Company or that, if available, such funds can be obtained on terms favorable to
the Company.

RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative
Instruments and Hedging Activities", which is effective for all fiscal quarters
of fiscal years beginning after June 15, 1999. SFAS No. 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 No. 133 will have on its financial statements, if any.

         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 is effective for periods
beginning after December 15, 1998. SOP No. 98-1 requires that the Company
capitalize certain costs incurred in connection with developing or obtaining
software for internal use. The Company currently capitalizes internal use
software obtained from third parties and expenses internal use software that it
develops. The Company is currently evaluating the impact SOP No. 98-1 will have
on its financial statements, if any.

YEAR 2000 COMPLIANCE

         The "Year 2000 issue," which presents potential risks and uncertainties
to virtually all businesses, is the result of computer programs that use two
digits rather than four to define the applicable year. Any computer programs
that have time-sensitive software may recognize a date using "00" as the year
1900 rather than the year 2000. This situation could result 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.

         The Company is continuing its evaluation and assessment of its
information technology and non-information technology systems, including
software, hardware and equipment that may be potentially affected by the Year
2000 issue. The Company estimates that its evaluation and assessment of these
systems will be completed shortly. The Company has and will continue to modify
and replace portions of its existing information technology systems so they will
function properly with respect to dates in the year 2000 and thereafter. The
Company believes that any Year 2000 issues with respect to its internal
information technology systems have been substantially resolved, and the
remainder will be resolved, by either internal software programming adjustments
or by the installation of Year 2000 compliant information systems. The Company
expects to complete substantially all modifications and replacements required
for Year 2000 compliance in its information systems prior to September 30, 1999.
The Company is also in the process of assessing non-information technology
system containing embedded chips that may be Year 2000 sensitive to identify
operating systems and equipment that are necessary or critical for continued
operations. The Company intends to test essential operating systems and
equipment containing embedded chips for Year 2000 compliance and to reprogram or
replace such equipment as appropriate. Based upon its assessments to date, the
Company is not aware of any significant Year 2000 issues in its control that
will not be resolved prior to the Year 2000.

         The Company has also extensively tested the technologies it sells for
Year 2000 issues. The Company believes that the technologies and services it
currently sells are Year 2000 compliant, but the Company intends to continue
testing to address any Year 2000 issues that may arise. The Company has made
available Year 2000 modifications, upgrades and replacement technology to its
customers that purchased prior technologies that were not Year 2000 compliant.
Metretek's website includes a listing of products that Metretek has identified
as either Year 2000 compliant, non-compliant, or compliant with qualifications
as noted. The Company intends to make all requisite modifications, replacements
and patches in order to resolve any Year 2000 issues that arise with respect to
technologies and services sold by the Company.

         The Company believes that the greatest risk from Year 2000 issues will
result from the failure of third parties, with which the Company has material
relationships, to become Year 2000 compliant. The Company relies on third party
service providers for services such as telecommunications, internet services,
utilities and other key services. Interruption of these services due to Year
2000 issues could materially adversely effect the Company's operations. The
Company has initiated communications with certain third parties, including
vendors, suppliers, service providers and customers, that the Company believes
are critical to its business operations and with respect to which the Company
believes Year 2000 issues could materially affect the Company's business.
Although the Company is not presently aware of any significant vendor, supplier,
service provider or customer that will have Year 2000 issues material to the
Company's operations, many businesses are resistant to providing any written or
binding assurances that they will be Year 2000 compliant. In addition, the
Company has no control over Year 2000 compliance programs by third parties.
Accordingly, the Company cannot provide any assurance that the systems of its
essential vendors, suppliers, service providers or customers will be Year 2000



                                       34
<PAGE>   35


compliant. The lack of Year 2000 compliance by such third parties could have a
material adverse impact on the Company's results of operations, financial
condition and business. If any such third parties (other than customers) are not
Year 2000 compliant and such non-compliance had or is likely to have a material
adverse effect on the Company, then the Company expects to utilize alternate
vendors, suppliers and service providers (subject to availability) which are
Year 2000 compliant. The Company intends to have in inventory a reserve of raw
materials, which it believes is sufficient to avoid a disruption in its
manufacturing process, to minimize the risk associated with third-party
suppliers experiencing Year 2000 issues.

         The Company expects total incremental costs (other than internal labor
time) of becoming Year 2000 compliant not to exceed approximately $200,000, of
which the Company has spent approximately $97,000 through December 31, 1998. The
Company intends to fund the costs associated with Year 2000 compliance through
operating cash flows and does not expect to defer any significant information
technology projects in order to become Year 2000 compliant. The Company intends
to capitalize and depreciate costs which represent investments in new or
upgraded technology that qualify as capital investments and to expense all other
costs as incurred.

         It is difficult to predict with a high degree of accuracy, and
impossible to guaranty, what impact any Year 2000 issues will have on the
Company. The Company is in the process of attempting to assess the most
reasonably likely worst case Year 2000 scenario, although the Company believes
that it, as most businesses, will not be able to identify such scenario with any
meaningful degree of certainty, given all the risks and uncertainties related to
the Year 2000 issue, many of which are outside of its control. The Company
currently anticipates a minimal level of disruption, inconveniences and
inefficiencies in its operations as a result of systems failures, primarily
related to non-compliance by third parties. The Company believes the risks are
greatest with respect to electric power and water supply, telecommunications and
transportation. Outages in any of these supplies could prevent the Company from
providing its services in measuring and monitoring the energy consumption of its
customers. Even if the Company could perform its services, these outages could
prevent or delay the delivery of the information results to its customers. If
the Company is unable to provide such services, then its revenues and results of
operation, will be materially reduced. Year 2000 issues may also cause temporary
delays in the delivery of raw materials and supplies, but the Company does not
expect any such delays to materially affect the Company's operations. Other
possible consequences include, but are not limited to, interruption of banking
and commercial payment systems, invoicing errors, collection difficulties,
inability to process customer transactions or otherwise engage in similar normal
business activities, which events are beyond the reasonable ability of the
Company to assess or control. There can be no assurance that Year 2000 issues
will not be material to the Company, or that the cost of interruptions with the
systems of third parties will not have a material adverse effect on the
Company's business, financial condition or results of operations.

         Although the Company has not created a specific contingency plan to
address the most reasonably likely worst case Year 2000 scenario, the Company is
in the process of developing contingency plans for certain Year 2000 problems,
such as identifying alternate vendors, suppliers and service providers,
identifying alternative methods for transmitting energy measurement and
monitoring information to its customers and preparing manual back-up methods for
certain software-intensive operations. However, as the Company continues to
assess the Year 2000 issue, in the event management believes it is warranted,
the Company will develop a specific Year 2000 "worst case" contingency plan. The
Company will continually refine its contingency plans throughout 1999 as
additional information becomes available.

         This section discussing Year 2000 issues contains forward-looking
statements. The costs and anticipated completion dates for Year 2000 compliance
by the Company and the estimated impact of Year 2000 issues on the Company are
based upon management's best estimates at this time, which were derived
utilizing numerous assumptions as to future events and third party activities,
including the continued availability of certain resources, third party
modifications plans and other factors, and may be updated from time to time as
additional information becomes available. However, the Company cannot guarantee
that these estimates will be achieved, and actual results could differ
materially from those anticipated. Specific factors that may cause such material
differences include, but are not limited to, the availability and costs of Year
2000 compliant technology, the ability to identify and correct all potential
Year 2000 sensitive issues, the ability of essential third parties to bring
their systems into Year 2000 compliance, the level of Year 2000 disruptions
experienced by the Company's vendors, suppliers, service providers and
customers, the success of any required contingency actions and similar
uncertainties.

         The Year 2000 statements in this document, as well as other Company
disclosures regarding Year 2000 issues, are intended to constitute "Year 2000
Readiness Disclosures" under the Year 2000 Information and Readiness Disclosure
Act.

EMPLOYMENT AGREEMENTS, CHANGE IN CONTROL ARRANGEMENTS AND OTHER COMPENSATION
ARRANGEMENTS

         The Company has entered into employment agreements with W. Phillip
Marcum, the President, Chief Executive Officer and Chairman of the Board of the
Company, and A. Bradley Gabbard, the Executive Vice President and Chief
Financial Officer of the Company. These employment agreements were amended on
December 3, 1998 to provide for an extension of the employment term until
December 3, 2001 for Mr. Marcum and until June 3, 2000 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
$210,000 for Mr. Marcum and $152,250 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 the Company to establish an incentive
compensation fund, to be administered by the Compensation Committee of the Board
of Directors, 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 the Company in the event of
a change of control of the Company or of the sale of substantially all of the
assets of the Company 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 of the Company 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 insurance plans of the Company for such additional period.
The employment agreements also contain certain restrictions on each employee'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 of a change in control of the Company. The agreements
provide that if within three years after a change in control of the Company, the
executive is terminated by the Company 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 insurance plans
of the Company 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: (i) any person or group becomes the
beneficial owner of 50% or 



                                       42
<PAGE>   43


more of the Company's Common Stock; (ii) a majority of the Company's 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; or
(iii) the Company approves a merger, consolidation, reorganization or
combination of the Company, other than one in which the voting securities of
the Company outstanding immediately prior thereto continue to represent more
than 50% of the total voting power of the Company or the surviving corporation
following such a transaction and the directors of the Company continue to
represent a majority of the directors of the Company or of the surviving        
corporation following such transaction; or (iv) the Company approves a sale of
all or substantially all of its assets.

         During 1998, under the Company's 1998 Employee Stock Purchase Plan, all
full-time employees of the Company, including Messrs. Marcum, Gabbard and McKee,
were entitled to purchase shares of the Company's Common Stock at fifty percent
(50%) of the market value of the Common Stock, based upon the closing sale price
of the Common Stock as reported on the Nasdaq National Market on the purchase
dates. A total of 47,244 shares of Common Stock were purchased by 48 employees,
including 10,966 shares purchased by Mr. Marcum, 5,918 shares purchased by Mr.
Gabbard, and 5,687 shares purchased by Mr. McKee. The 1998 Employee Purchase
Plan was discontinued in July 1998.

STOCK OPTION GRANTS

         On October 6, 1998, the Company repriced all stock options held by its
officers, employees and directors. The exercise price of all such options was
reduced to $2.00, the last sale price of the Common Stock as reported on the
Nasdaq National Market on the date of repricing. The terms of the options
reissued to effect the repricing were generally identical to the terms of the
options cancelled, except that (i) repriced options held by officers and
employees will not be exercisable prior to October 6, 1999 as a result of a one
year exercise blackout period, whether or not the cancelled options were
previously vested and exercised, and thereafter the options will be subject to
the original vesting conditions, and (ii) all repriced options held by Mr.
Marcum and Mr. Gabbard will be deemed vested as of October 6, 1999, irrespective
of prior vesting conditions. Options held by the Board of Directors of the
Company and the Named Executive Officers were included in the repricing.

         The stock option repricing acknowledged the importance to the Company
of its officers, employees and directors and of the incentive to serve the
long-term best interests of the Company provided by stock options. In deciding
to authorize the repricing, the Board of Directors and the Compensation
Committee considered such factors as the competitive environment for obtaining
and retaining qualified employees, the advantage to the Company of utilizing
stock options as a non-cash method of compensation, and the overall benefit to
the stockholders from providing such persons with long-term equity incentives.
The Board of Directors believes that as a result of the decline in the Company's
stock price, outstanding options with exercise prices well in excess of the then
current stock price were not providing meaningful compensation or incentives for
the Company's officers, employees and directors. The Board of Directors also
believes that the future growth and the success of the Company is dependent upon
its ability to successively attract, retain and motivate its officers, employees
and directors. The Board of Directors believes that the use of stock options
aligns the interest of the optionees with the interest of stockholders, which is
in the best interest of the stockholders. Based upon all of the foregoing, and
other relevant factors, the Board of Directors agreed with the conclusion of the
Compensation Committee that a reduction in the exercise price of outstanding
options held by officers, employees and directors to market levels was necessary
and appropriate to provide meaningful incentives to option holders to operate
the Company with the goal of maximizing stockholder value and to provide
appropriate compensation for services. A total of 


                                       43
<PAGE>   44


120,000 options held by Mr. Marcum, 44,500 options held by Mr. Gabbard and
12,500 options held by Mr. McKee were repriced to $2.00 per share.

         The following table sets forth information with respect of stock
options granted during fiscal 1998 to the Named Executive Officers. No stock
appreciation rights ("SARs"), alone or in tandem with stock options, were
awarded in 1998. The Named Executive Officers did not exercise any stock options
during 1998.

         price equal to the fair market value of the Common Stock on the date of

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

(1)      For purposes of this table, the value of unexercised in-the-money 
         options is calculated based upon the difference between $2.125, the
         closing sale price of the Common Stock on such date as reported on the
         Nasdaq National Market, and the option exercise price.

(2)      The unexercisable options included in this table are options that were
         granted prior to 1998 and then cancelled and regranted in the 1998
         stock option repricing. Pursuant to a one year exercise blackout period
         imposed under the terms of that repricing, the unexercisable options do
         not become exercisable until October 6, 1999, on which date they become
         fully vested.

(3)      The exercise price of these options exceeded $2.125, the closing sale
         price of the Common Stock on December 31, 1998 as reported on the
         Nasdaq National Market.

DIRECTOR COMPENSATION

         Directors who are officers or employees of the Company or any of its
subsidiaries 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
officers or employees of the Company or any of its subsidiaries ("Non-Employee



                                       45
<PAGE>   46


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
granted by the Company. Until June 1998, such options were granted under the
Company's Directors' Stock Option Plan (the "Directors' Plan"). Since June 1998,
all such options are granted under the Company's 1998 Stock Incentive Plan (the
"1998 Plan"). Under the formula for these stock option grants, which is the same
in both the Directors' Plan and the 1998 Plan, 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 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 to receive additional stock options ("Meeting Options") under the
1998 Plan 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 repriced to $2.00 per share, the closing sales price of the Common
Stock as reported on the Nasdaq National Market on such date. As of December 31,
1998, options to purchase 110,000 shares of Common Stock were outstanding to
Non-Employee Directors under the Directors' Plan and options to purchase 17,428
shares of Common Stock were outstanding under the 1998 Plan, all at an exercise
price of $2.00 per share.

        On March 7, 1997, options to purchase 12,500 shares of Common Stock were
granted to Stephen E. McGregor, a former director of the Company, and options to
purchase 2,500 shares of Common Stock were granted to Mr. Lloyd under the
Directors' Plan at an exercise price that was reduced in the 1998 stock option
repricing to $2.00 per share, for personal services rendered in connection with
a Metretek strategic alliance.

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

(1)      The Number and Percent of Class of Shares Beneficially Owned is
         determined in accordance with Rule 13d-3 under the Exchange Act and the
         information is not necessarily indicative of beneficial ownership for
         any other purpose. Under such rule, beneficial ownership includes any
         shares as to which the beneficial owner has voting power or investment
         power and any shares that the beneficial owner has the right acquire
         within 60 days of March 16, 1999 through the exercise of any stock
         option, warrant or other right to acquire shares of Common Stock. In
         additional, such shares are deemed to be outstanding in calculating the
         Percent of Class of such beneficial owners, but are not deemed to be
         outstanding in calculating the Percent of Class of any other beneficial
         owner. Unless otherwise indicated in the footnotes, each beneficial
         owner has sole voting and investment power (or shares such powers with
         his or her spouse) with respect to the shares shown as beneficially
         owned, subject to community property laws where applicable.

(2)      The Percent of Class is based upon 3,473,343 shares of Common Stock
         outstanding as of March 16, 1999.

ITEM 12. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS


         On March 7, 1997, options to purchase 12,500 shares of Common Stock
were granted to Stephen E. McGregor, a former director of the Company, and
options to purchase 2,500 shares of Common Stock were granted to Mr. Lloyd under
the Directors' Plan at an exercise price that was reduced in the 1998 stock
option repricing to $2.00 per share for personal services rendered in connection
with a Metretek strategic alliance. 

         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 Energy Services, Inc. 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, the Chairman of the Board, President
and Chief Executive Officer and a director of the Company, is also a director of
Key Energy Services, Inc.

         On May 4, 1998, in connection with the Company's acquisition, through
Metretek, of certain assets of a wholly owned subsidiary of American Meter,
Metretek entered into a 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 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 products in the United
States and Canada at certain agreed-upon prices. Subsequent to the acquisition,
Metretek and American Meter 


                                       49
<PAGE>   50


entered into an international sales agreement, pursuant to which American Meter
and its affiliates have the non-exclusive right to sell Metretek products
internationally. Harry I. Skilton, the President, Chief Executive Officer and a
director of American Meter, became a member of the Board of Directors in
connection with this acquisition. During fiscal 1998, the Company recorded
revenues from American Meter of approximately $522,000 with respect to sales
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 the Company and any related party is
approved by a majority of the members of the Board of Directors of the Company
who are disinterested in the transaction.

INDEPENDENT AUDITORS' REPORT


To the Board of Directors and Stockholders of
  Marcum Natural Gas Services, Inc.:

We have audited the accompanying consolidated balance sheets of Marcum Natural
Gas Services, Inc. and subsidiaries as of December 31, 1998 and 1997, 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 generally accepted auditing
standards. 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 Marcum Natural Gas Services, Inc.
and subsidiaries at December 31, 1998 and 1997, and the results of their
operations and their cash flows for the years then ended in conformity with
generally accepted accounting principles.

MARCUM NATURAL GAS SERVICES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS FOR THE
YEARS ENDED DECEMBER 31, 1998 AND 1997
--------------------------------------------------------------------------------


1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         ORGANIZATION AND PROPOSED NAME CHANGE - The accompanying consolidated
         financial statements include the accounts of Marcum Natural Gas
         Services, Inc. ("MNGS") and its wholly owned subsidiaries, Southern
         Flow Companies, Inc. ("Southern Flow"), Metretek, Incorporated
         ("Metretek") (and its wholly-owned subsidiaries, Metretek Europe,
         Limited ("Metretek Europe"), and Sigma VI, Inc. ("Sigma VI")), Marcum
         Gas Transmission, Inc. ("MGT") (and its wholly-owned subsidiary Marcum
         Capital Resources, Inc. ("MCRI")), and Marcum Denver, Inc. (formerly
         Marcum Fuel Systems, Inc.), collectively referred to as the Company.

         MNGS was incorporated on April 5, 1991. The focus of its continuing
         business operations is in two areas relating to the natural gas
         industry: 1) the design, manufacture and distribution of automated
         energy consumption monitoring and recording systems, and 2) natural gas
         measurement 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. Each area of
         business operation is considered to be a reportable segment - see Note
         8.

         In March 1999, the Board of Directors of the Company adopted a
         resolution authorizing an amendment to the Company's Restated
         Certificate of Incorporation, as amended, to change the name of the
         Company to "Metretek Technologies, Inc." The change of the Company's
         name is subject to approval by the stockholders of the Company. The
         Board of Directors intends to include the proposal to change the
         Company's name in the Proxy Statement for the Annual Meeting of
         Stockholders currently scheduled to be held on June 7, 1999.

         PRINCIPLES OF CONSOLIDATION - The consolidated financial statements
         include the accounts of MNGS 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 stockholder's equity, 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.

         equivalents. Supplemental statement of cash flows information is as
         follows:

         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, 1998 and 1997 are $420,165
         and $563,672, 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.

         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 adopted Statement of
         Financial Accounting Standards ("SFAS") 130, "Reporting Comprehensive
         Income," effective January 1, 1998. SFAS 130 establishes rules for the
         reporting of comprehensive income and its components. The Company's
         other comprehensive income (loss) consists of foreign currency
         translation adjustments and is presented in the Consolidated Statement
         of Stockholders' Equity. The adoption of SFAS 130 had no impact on the
         Company's total stockholders' equity. Prior year financial statements
         have been reclassified to conform to the SFAS 130 requirements.

         INCOME (LOSS) PER SHARE - The Company's net income/loss from continuing
         operations, loss from discontinued operations and net loss, for
         purposes of computing the basic and diluted per share amounts, are
         identical. The following is a reconciliation of the weighted average
         shares outstanding to the weighted average shares outstanding assuming
         dilution:

         STOCK BASED COMPENSATION - The Company has utilized 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
         utilized 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 SFAS 133, "Accounting for
         Derivative Instruments and Hedging Activities," which is effective for
         all fiscal quarters of fiscal years beginning after June 15, 1999. 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.

         COST 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 is
         effective for periods beginning after December 15, 1998. SOP No. 98-1
         requires that the Company capitalize certain costs incurred in
         connection with developing or obtaining software for internal use. The
         Company currently capitalizes internal use software obtained from third
         parties and expenses internal use software that it develops. The
         Company is currently evaluating the impact SOP No. 98-1 will have on
         its financial statements, if any.

2.       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 is a
         wholly owned subsidiary of American Meter Company ("American Meter"),
         which is ultimately controlled by Ruhrgas AG, a German corporation. 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 $1,200,000 convertible
         subordinated promissory note ($600,000 of which is contingent upon
         Metretek exceeding certain sales targets, as discussed below) (the
         "American Meter Note"). The purchase price is subject to upward
         adjustment based upon Metretek's actual sales of products in the
         acquired business during the 18-month period that commenced July 1,
         1998. If Metretek's annualized sales of products in the business
         acquired are greater than $3,900,000 during such period, then the
         purchase price will be increased on a dollar-for-dollar basis to the
         extent of such sales surplus, but the purchase price will not be
         increased above $4,500,000 even if annualized sales are greater than
         that amount. Any increase in the purchase price will be reflected as an
         adjustment to the principal balance of the American Meter Note and
         allocated to goodwill. 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.

         Up to $1,028,107 of the American Meter Note is convertible at any time
         at the option of American Meter Software, into 180,766 shares of Common
         Stock of the Company at the rate of approximately 


                                      F-11
<PAGE>   66


         $5.69 of principal per share. The American Meter Note bears interest on
         the unpaid principal balance at a fixed rate equal to 7.5% per annum,
         payable quarterly in arrears. The American Meter Note is due and
         payable May 4, 2002, and may be prepaid at any time without penalty or
         premium. The Company granted to American Meter Software the one-time
         option to cause the shares of Common Stock issued at the closing or
         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.

         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) have been allocated as follows:

3.       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 Southern Flow and Metretek 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 or the
         programs are liquidated.

         The Company incurred a loss from operations of the discontinued MGT
         operations of $33,884 and income from operations of MGT of $408,716
         during the years ended December 31, 1998 and 1997, respectively.
         Revenues from the discontinued MGT operations were $269,873 and
         $780,314 for the years ended December 31, 1998 and 1997, respectively.
         The Company does not expect to incur a loss from the sale or
         liquidation of the MGT operations.

         In 1997, the Company, through its wholly-owned subsidiary, Marcum Fuel
         Systems, Inc. ("MFS"), sold its refueling equipment business and
         substantially all of the operating assets related thereto to Natural
         Fuels Corporation ("Natural"), an affiliate of Public Service Co. of
         Colorado and Colorado Interstate Gas, pursuant to the provisions of an
         Asset Purchase Agreement, dated as of June 27, 1997 (the "Asset
         Purchase Agreement").

         The assets sold by MFS to Natural included certain inventory,
         equipment, contracts, patents, trademarks and technology of MFS used in
         the compressed natural gas vehicle fueling business, but excluded
         receivables and payables (other than those attributed to assumed jobs),
         certain inventory and contracts attributable to jobs in progress as of
         the closing date, and the capital stock of its wholly-owned
         subsidiaries.

         Pursuant to the Asset Purchase Agreement, (a) Natural paid MFS $373,628
         in cash at closing; (b) Natural agreed to pay an additional $47,735 in
         cash for certain vehicles and equipment upon transfer of title to such
         vehicles and equipment; (c) Natural assumed the warranty and service
         obligations of MFS with respect to jobs completed by MFS and certain
         liabilities and obligations of MFS in connection with pending jobs and
         job quotes assumed by Natural; (d) Natural agreed to pay MFS 30% of the
         gross margin upon Natural's completion of the assumed jobs; and (e)
         Natural agreed to pay MFS a royalty on the sale by Natural and its
         affiliates of compressed natural gas vehicle refueling dispensers that



                                      F-13
<PAGE>   68


         incorporate MFS metering technology in an amount equal to (i) $750 per
         dispenser sold until the earlier of the sale of the first 500
         dispensers or five years from the closing date, plus (ii) $500 per
         dispenser sold thereafter until the earlier of the sale of 500
         additional dispensers or five additional years. MFS also granted to
         Natural a one-year license of the name "Marcum Fuel Systems, Inc." and

</TABLE>




         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% (8.75% at
         December 31, 1998) 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 (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. Borrowings on the 


                                      F-14

         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
         inventory (up to a combined maximum of $1,500,000) of Southern Flow and
         Metretek.

         At December 31, 1998, the Company had a combined $4,375,458 Loan
         availability, of which $2,561,702 had been borrowed by Southern Flow
         and Metretek, leaving $1,813,756 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, 1998 consists of the
         American Meter Note incurred in connection with the acquisition
         discussed in Note 2.

5.       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 July 24,
         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. The
         Company intends to appeal that ruling to the Colorado Supreme Court.
         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, 1998 and 1997 totaled $1,119,290 and
         $918,669, 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, 1998 and 1997 was $146,161 and $147,061,
         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 1998 and 1997 under the license
         agreement.

6.       INCOME TAXES

         No tax expense or benefit has been recognized during the years ended
         December 31, 1998 and 1997 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, 1998 and 1997.

         At December 31, 1998, the Company had unused net operating losses to
         carry forward against future years' taxable income of approximately
         $20,806,000 expiring in various amounts from 1999 to 2013. At December
         31, 1998, the Company had unused investment tax credits, general
         business tax credits, and research and development tax credit
         carryforwards aggregating approximately $151,000 expiring in various
         amounts from 1999 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 $4,568,000 expiring between 1999 and 2002. As a result of the change
         in ownership, 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
         $948,000 ($231,000, net of current limitation). Such carryforwards
         expire in 1999 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.

7.       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 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.

<PAGE>   72


         No Warrants have been exercised through December 31, 1998.

         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
         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 Marcum Natural Gas Services, 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 will not be affected by the adoption of
         the 1998 Stock Incentive Plan.

         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 is authorized to purchase up to
         approximately 7% of its outstanding Common Stock in open market
         transactions, from time to time as management deems appropriate, if the
         market price of the Company's stock remains below certain levels. The
         Company may use the repurchased shares for employee benefit plans and
         other corporate purposes, may hold the repurchase shares in treasury or
         may retire the purchased shares. Through December 31, 1998, the Company
         repurchased 57,088 shares of its Common Stock at an average price of
         $2.25 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) shall be exercisable prior to October 6, 1999. The other terms
         of the outstanding stock options generally remain unchanged. The
         repriced options are reflected as forfeitures and new grants during the
         year ended December 31, 1998 in the summary above.

         The weighted average grant date fair values of options granted
         (including repriced options in 1998), during the years ended December
         31, 1998 and 1997 were $.77 and $1.36 per option, respectively. The
         range of exercise price for options outstanding as of December 31, 1998
         was $2.00 to $2.44. The weighted average remaining contractual life of
         options outstanding at December 31, 1998 was approximately 6.7 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 a variation of
         the Black-Scholes stock option valuation model with the following
         weighted average assumptions for grants in 1998 and 1997: stock price
         volatility at 40% and 40%, respectively; risk-free rate of return of 5%
         and 5.5%, 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 one one-hundredth
         of a share of Series C Preferred Stock of the Company at an initial
         exercise price of $100 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. The
         warrants vest in increments based upon the last sales price of the
         Company's Common Stock as reported on the Nasdaq Stock Market achieving
         the minimum levels set forth below. The exercise price of the
         respective warrants will be equal to the minimum stock prices as the
         warrants vest.

</TABLE>



         At December 31, 1998, 12,500 of the warrants were vested and
         exercisable. All warrants that are not vested at March 13, 2000 shall
         expire without vesting. All of the warrants expire March 13, 2003,
         regardless of the date the warrants vest or become exercisable.

         In September 1994, the Company settled a lawsuit related to a dispute
         over services rendered by an individual in connection with the
         acquisition of Southern Flow. As part of the settlement, the Company
         issued 10,000 stock purchase warrants which entitle the holder to
         purchase one share of Common Stock at $17.00 per share, the market
         price of the stock on the settlement date. The warrants are exercisable
         and expire September 27, 1999.

         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 from 1999 to 2004.

         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 


                                      F-20
<PAGE>   75


         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.

8.       SEGMENT AND RELATED INFORMATION

         The Company adopted SFAS 131, "Disclosures About Segments of an
         Enterprise and Related Information," effective January 1, 1998. 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 two reportable business segments: automated energy data
         management; and natural gas measurement 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 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
         relates to segment profit, income and expense not allocated to
         reportable segments.
