                               PROSPECTUS SUMMARY



         The following summary highlights information appearing elsewhere in
this prospectus. This summary does not contain all of the information that you
should consider before investing in our securities. You should read carefully
the entire prospectus, including the risks discussed in "Risk Factors" and the
consolidated financial statements and related notes, before deciding to invest
in our securities. Unless otherwise specified, all information in this
prospectus has been adjusted to reflect the 1-for-4 reverse split of our common
stock effected in July 1998.

                           METRETEK TECHNOLOGIES, INC.

OUR BUSINESS

         We are a diversified provider of energy measurement products, services
and data-management systems to industrial and commercial users and suppliers of
natural gas and electricity. In June 1999, we changed our name from "Marcum
Natural Gas Services, Inc." to "Metretek Technologies, Inc." We currently
conduct our continuing operations through three subsidiaries:

     o   PowerSpring, Inc., based in Denver, Colorado, operates our
         Internet-based business to business energy services hub.

     o   Metretek, Incorporated, based in Melbourne, Florida, which we refer to
         in this prospectus as Metretek Florida, designs, manufactures and sells
         electronic devices and systems, commonly referred to as automatic meter
         reading systems, which we refer to in this prospectus as 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.

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

         We are a corporation organized under the laws of the state of Delaware
on April 5, 1991. Our principal executive offices are located at 1675 Broadway,
Suite 2150, Denver, Colorado 80202. Our telephone number is (303) 592-5555.

OUR BUSINESS STRATEGY

         Our business strategy is to position ourselves as an integrated
provider of data measurement products, services and systems that enhance the
flow of information to the energy industry. To date, our products and services
have been marketed primarily at the natural gas industry, but we intend to
provide our products and services to other segments of the energy industry,
particularly the electricity industry. The energy industry generally is
undergoing fundamental regulatory and structural changes and trends. Our
strategy is to acquire, develop and operate businesses that are positioned to
take advantage of these trends. While we regularly engage in discussions
relating to potential acquisitions and dispositions, we have no present
agreements or commitments with respect to any material acquisition or
disposition.

OUR RECENT INTERNET-BASED BUSINESS STRATEGY

         We have recently focused a major part of our business strategy upon the
development of an Internet-based business, which we conduct through PowerSpring.
In furtherance of this Internet-based business strategy, we have retained Scient
Corporation, a leading Internet business systems and strategy advisor, to assist
us in designing, developing and implementing our Internet-based business. The
goal of PowerSpring is to provide comprehensive energy consumption data and a
broad array of additional information designed to facilitate the purchase and
management of natural gas by commercial users of natural gas. PowerSpring also
intends to provide commercial electricity users with a mechanism to manage their
energy needs and reduce their electricity costs. Our initial focus is the
development of a website to provide a single source of information and services
for commercial energy users. Through its website, which was launched in June
2000, PowerSpring's strategy is to provide an online energy marketplace for
commercial and industrial energy users.

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

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

         Since September 1999, Scient has been assisting and advising us in the
design, development and implementation of our Internet-based business strategy.
On March 17, 2000, we acquired Mercator Energy Incorporated through a merger
with a wholly-owned subsidiary of PowerSpring. Mercator is a Denver-based
natural gas services and brokerage company that acts as an independent
broker-agent for both producers and users of natural gas and energy. We believe
that through this acquisition, PowerSpring has gained an expertise in the area
of energy procurement, which is an important element in our Internet business
strategy.

         Our primary Internet-based business product is being designed to
provide a complete turn-key solution for the commercial natural gas customer and
to reduce or eliminate many of the market entry barriers. We anticipate that
this Internet-based business product will require no up-front capital investment
by the customer, will be seamless in its application to the customer, and will
be perceived by the customer as having a small overall cost compared to the
potential savings in energy costs. We believe that PowerSpring's customers will
realize a savings in energy costs as well as receive access to current and
historical value added consumption reports through PowerSpring's website.

         The initial focus of PowerSpring is the natural gas market, which has
been almost fully deregulated. However, we believe that the historical structure
and operating mechanics of the electricity markets are very similar to the
natural gas markets. We have designed our AMRs and software management programs
for application in the electricity markets as well. In addition, the domestic
electricity markets are about three times the size of the domestic natural gas
markets.

UNITS PRIVATE PLACEMENT

         On February 4, 2000, we completed a $14,000,000 private placement,
which we refer to in this prospectus as the units private placement, of 7,000
units, including 1,450 units we issued on December 9, 1999. Each unit consisted
of 200 shares of common stock, 1 share of Series B preferred stock and warrants,
which we refer to in this prospectus as unit warrants, to purchase 100 shares of
common stock. In the units private placement, we issued 1,400,000 shares of
common stock, 7,000 shares of Series B preferred stock and unit warrants to
purchase 700,000 shares of common stock. The units private placement was
approved and ratified by our stockholders at a special meeting held on February
3, 2000. The units were issued to institutional investors and other "accredited
investors" under Regulation D under the Securities Act. The primary purpose of
the units private placement was to raise capital to enable us to develop the
Internet-based business of PowerSpring. A portion of the proceeds was used to
repay outstanding indebtedness, and the remaining proceeds are being used for
general corporate and working capital purposes.

              redemption, at an average exercise price of $9.63 per share;

         o    1,179,762 shares of common stock issuable upon the conversion of
              7,000 shares of Series B preferred stock at a conversion rate of
              $5.9334 per share; and

         o    405,507 shares of common stock reserved for future issuance under
              our stock plans.

         The number of shares of common stock outstanding after this offering
listed above assumes all warrants that we have called for redemption are
exercised on or before the redemption date. However, because there are no
commitments to purchase shares in the offering, the number of warrants that will
be exercised, and thus the number of shares of common stock that will be issued
in, and outstanding after, this offering is not presently determinable.

                                  RISK FACTORS

         An investment in our securities involves risk. You should carefully
consider the risks described below, along with the other information contained
or incorporated by reference in this prospectus, before making an investment
decision. If any of the following risks were to occur, our business, prospects,
assets, financial condition, results of operations and cash flows could be
materially adversely affected. When we say that something could or will have a
material adverse effect on us or our business, we mean that it could or will
have one or more of these effects. If this occurs, the trading price of our
securities would likely decline, and you could lose all or part of your
investment.

                          RISKS RELATED TO OUR BUSINESS

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

         We have incurred net losses on an annual basis during each year since
our incorporation. We incurred net losses of approximately $0.3 million and $3.7
million for the years ended December 31, 1998 and 1999, and a net loss
attributable to common stockholders of approximately $6.8 million for the
quarter ended March 31, 2000. At March 31, 2000, we had an accumulated deficit
of approximately $29.5 million. Due to the design, creation and implementation
our Internet-based business strategy, which will require us to make significant
expenditures, we expect operating losses to continue for the foreseeable future.
We also anticipate increased expenses as we support, expand and improve
PowerSpring and its infrastructure, invest in new Internet applications, enhance
our management expertise, expand our sales efforts and pursue strategic Internet
relationships. We may never generate sufficient revenues to achieve
profitability. Even if we do achieve profitability, we may not be able to
sustain or increase that profitability on a quarterly or annual basis in the
future.

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

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

         We estimate that the initial development phase to launch the business
of PowerSpring will require total expenditures of approximately $12 million,
consisting primarily of research and development costs, consulting fees and
expenses and costs of acquiring the requisite technology, including hardware and
software. Through March 31, 2000, these costs were approximately $4.6 million.
We expect that after this initial development stage is completed, the further
development and expansion of PowerSpring, including staffing, organizational and
start-up expenses, marketing costs and additional capital expenditures, will
require significant additional funds. We intend to raise any needed additional
capital to fund the development and operations of PowerSpring primarily through
financing at the PowerSpring level. However, we may also or instead raise
additional capital at the Metretek level. For example, the net proceeds of this
offering will be used primarily to fund the development of PowerSpring.

         Virtually any capital raising will require the consent of our lender on
our credit facility, if the credit facility is then in effect. In addition, any
capital raising could also require the consent of the holders of our Series B
preferred stock. We cannot assure you that any additional funds will be
available to us or, if available, can be obtained on terms favorable to us and
on terms acceptable to our lender and to the holders of the Series B preferred
stock, if their consents are required. Our inability to raise sufficient
additional funds to meet the capital requirements of PowerSpring would have a
material adverse effect on our business, financial condition and results of
operations.

         In addition to our need to raise capital to fund PowerSpring, we will
need to raise additional capital in the future to either repay or refinance any
indebtedness we incur in the future. The Series B preferred stock bears a
cumulative dividend at the rate of 8% per year and, if it is not earlier
converted into common stock, we are required to redeem the Series B preferred
stock on December 9, 2004 at a redemption price equal to the liquidation
preference, currently $7,000,000 plus accrued and unpaid dividends. We will also
require additional capital in the future to make any significant acquisitions of
businesses or technologies.

         We have a $5 million revolving line of credit with our current lender
which expires in March 2001. Our ability to borrow funds under this credit
facility is limited to our loan availability based upon our assets, primarily
our accounts receivable and inventory, and is limited to $3 million by the terms
of the Series B preferred stock. As of March 31, 2000, we had a total loan
availability of approximately $3.8 million, and of that we had borrowed less
than $0.1 million. The



                                       5
<PAGE>   8


amount of our loan availability, as well as the amount we borrow, will change in
the future depending on our asset base and our capital requirements. Any amount
outstanding under our credit facility in March 2001 will need to either be
repaid by us, refinanced by a new lender or investor, or extended by our current
lender. We cannot estimate the amount that we will have borrowed under the
credit facility when it expires, and we cannot assure you that we will be able
to repay, refinance or extend that indebtedness at that time.

         To finance PowerSpring and the growth of our other businesses, and to
repay or refinance any indebtedness we might incur, we will need to raise a
substantial amount of additional capital from the public or private sales of
equity securities, debt financing, sales of assets, calling the dividend
warrants for redemption, or from other sources. Additional financing may not be
available to us when we need it or, if available, it may not be on terms
satisfactory to us, or we may not be able to obtain the required consents to
complete the financing. Obtaining additional financing will depend on many
factors, including market conditions, our operating performance and investor
sentiment. Terms of debt financing could restrict our ability to operate our
business or to expand our operations. If we are unable to raise sufficient
additional financing on terms satisfactory to us, then our business will be
materially and adversely affected.

         In addition, if we raise capital by issuing capital stock or securities
convertible into capital stock, our stockholders could suffer a significant
dilution of their percentage ownership interests, and the new capital stock or
other new securities could have rights, preferences or privileges senior to
those of our current stockholders.

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

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

         o    the size, timing and terms of sales and orders;

         o    the amount and timing of expenditures on PowerSpring;

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

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

         o    the pace of development of PowerSpring;

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

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

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

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

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

         o    the mix of products and services sold;

         o    the mix of international and domestic revenues;

         o    the life cycles of our products and services;

         o    budgeting cycles of utilities;

         o    general economic and political conditions;

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

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

         o    prices charged by our suppliers;

         o    costs related to future acquisitions of technology or businesses;

         o    the level of service and price competition;

         o    changes in our operating expenses;



                                       6
<PAGE>   9


         o    the success of our brand building and marketing campaigns for
              PowerSpring's products and services; and

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

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

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

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

         Our business strategy and future success is highly dependent upon our
ability to develop our business. Our Internet-based business strategy is based
on an unproven business model, and our operating, sales and other strategies are
still being developed. The success of our Internet-based business strategy will
depend on the willingness of commercial users of natural gas and electricity to
purchase a package consisting of energy data management equipment and energy
purchasing resources. It will also depend on our ability to successfully develop
and market a business that offers energy products, services and information over
the Internet. PowerSpring's website was launched in June 2000. Accordingly, we
have no operating history to provide you upon which you can evaluate
PowerSpring.

         As a company developing a new business in the new and rapidly evolving
markets for Internet products and services generally, and online energy
products, services and information specifically, we face numerous risks and
uncertainties, some of which relate to our ability to:

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

         o    anticipate and adapt to the changing Internet market;

         o    attract customers to PowerSpring;

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

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

         o    attract, retain and motivate qualified personnel;

         o    respond to actions taken by our competitors;

         o    integrate acquired businesses, technologies, products and
              services;

         o    generate revenues and sales of new products and services;

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

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

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

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

         Our goal is to derive a significant amount of our revenues, income and
cash flow from our PowerSpring Internet operations. We cannot assure you that
Internet-based commerce for energy products and services, especially by
commercial users of energy, will ever be widely accepted by our current or
potential future customers. Our business would suffer if the market for
Internet-based commerce for energy products and services fails to develop or
develops



                                       7
<PAGE>   10


more slowly than expected. Our business would also suffer if we are unable to
adapt to new forms of, or new pricing models for, Internet-based commerce for
energy products and services.

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

         o    the Internet's ability to handle increased activity;

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

         o    potential changes in government regulation;

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

         o    access costs;

         o    the performance and reliability of products and services as the
              number of users and amount of traffic increases;

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

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

         Moreover, critical issues concerning the commercial use of the
Internet, including data corruption, cost, ease of use, accessibility and
quality of service, remain unresolved and may negatively affect commerce on the
Internet. These issues will need to be addressed in order for the market for
online energy products and services to grow.

         It is difficult to predict when Internet-based commerce for energy
products and services will emerge and obtain market acceptance and be
profitable. This makes it difficult to project our future revenues, results of
operations and cash flows. We cannot assure you that we will be successful in
selling energy products and services over the Internet or in capturing a
significant share of the market for Internet-based energy products and services.

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

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

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

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

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



                                       8
<PAGE>   11


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

         Our anticipated future growth as a result of PowerSpring may place a
significant strain on our management, operating systems and resources. We cannot
successfully implement our Internet-based business strategy if we fail to manage
our growth. We expect that we will need to attract and retain competent
personnel and to continue to improve our financial managerial controls and
reporting systems and procedures. We will also need to continue to expand and
maintain close coordination among our technical, accounting, finance and sales
and marketing organizations. In addition, our systems, procedures or controls
may be inadequate to support our operations, in which case management may be
unable to exploit opportunities for our products and services. Failure to manage
our growth effectively and to successfully integrate any acquisition or
strategic relationships could materially adversely affect our business.

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

         The electricity industry is currently undergoing fundamental structural
changes due to deregulation, similar to what the natural gas utility industry
has undergone. A key component of our business strategies, in both our
traditional businesses, especially Metretek Florida, and our new Internet-based
business, is to take advantage of opportunities created by the deregulation of
the electricity industry as the result of the need for more frequent electricity
consumption information. A principal expected benefit to us of electricity
deregulation is that commercial and industrial electricity customers would be
able to purchase electricity directly from multiple suppliers, rather than
solely from the local utility. This will require these electricity customers to
obtain timely electricity consumption data. If the deregulation does not
continue or slows down, or if the market is slow to respond to the opportunities
made available by deregulation of the electricity industry, then commercial
electricity customers may not purchase our products as anticipated, if at all.

BECAUSE WE ARE DEPENDENT UPON THE UTILITY INDUSTRY FOR A SIGNIFICANT PORTION OF
OUR REVENUE, CONTINUED REDUCTIONS OF PURCHASES OF OUR PRODUCTS AND SERVICES BY
UTILITIES WILL MATERIALLY AND ADVERSELY AFFECT OUR GROWTH STRATEGY

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

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

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



                                       9
<PAGE>   12


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

         o    incur additional indebtedness;

         o    create liens or other encumbrances;

         o    issue or redeem securities;

         o    make dividend payments and investments;

         o    amend our charter documents;

         o    sell or otherwise dispose of our assets;

         o    liquidate or dissolve;

         o    merge or consolidate with other companies; or

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

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

         o    limited in how we conduct our business;

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

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

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

         As the result of issuing the Series B preferred stock, we are
recognizing the 8% coupon rate and "deemed distributions" as dividends on the
Series B preferred stock. The proceeds from the sale of the units were allocated
to the common stock, the unit warrants and the Series B preferred stock based on
the relative fair value of each. This allocation process resulted in the Series
B preferred stock being initially recorded at a discount from its $1,000 per
share liquidation value. This discount will be recorded as a distribution over
the term of the Series B preferred stock. Another discount results from the
increase in the fair market value of a share of our common stock from the date
we offered to sell the final 5,550 units to February 4, 2000, the date we issued
those units. This increase caused the conversion feature of the Series B
preferred stock to be "in the money" on February 4, 2000. The discount related
to the "in the money" conversion feature will be recorded as a distribution
between the February 4, 2000 and June 9, 2000, after which date the Series B
preferred stock can be converted into our common stock. The Series B preferred
stock dividends will increase our future net loss available to common
shareholders and net loss per common share, which could adversely affect the
trading price of our common stock.

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

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

         o    effectively use and develop leading technologies;

         o    continue to develop our technical expertise;

         o    enhance our current products and services;

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

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



                                       10
<PAGE>   13


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

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

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

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

         The margins recognized from some of our product and service offerings
is higher than the margins on our other product and service offerings. For
example, revenues from sales of some of Metretek Florida's AMRs have
significantly higher margins than Metretek Florida's contract manufacturing
revenues. In addition, we do not know what the prices and costs of our future
PowerSpring products and services will be and therefore we cannot estimate their
margins. These new PowerSpring products and services may have lower margins than
our current businesses. If in the future we derive a proportionately greater
percentage of our revenues from lower margin products and services, then our
overall margins on our total revenues will decrease and, accordingly, will
result in lower net income, or higher net losses, and less cash flow on the same
amount of revenues.

OUR MANAGEMENT OF PRIVATE ENERGY PROGRAMS PRESENTS RISKS TO US

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

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

         o    lawsuits by investors in a program who become dissatisfied with
              the result of the program;

         o    changes in the regulatory environment relating to these programs;

         o    reliance upon significant suppliers and customers by these
              programs;

         o    hazards of energy facilities; and

         o    changes in technology.

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

WE MAY BE UNABLE TO SUCCESSFULLY EXPAND OUR INTERNATIONAL OPERATIONS, WHICH
COULD LIMIT OUR GROWTH AND MAY ADVERSELY AFFECT OUR BUSINESS



                                       11
<PAGE>   14


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

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

         o    adverse changes in applicable laws and regulatory requirements;

         o    import and export 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;

         o    potential adverse tax consequences;

         o    cultural and language difficulties;

         o    the potential exchange and repatriation of foreign earnings;

         o    localization and translation of products and services;

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

         o    the impact of local economic conditions and practices.

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

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

         The markets for energy products, services, technology and information
are highly competitive. We also anticipate that PowerSpring will face intense
competition, especially if the use of the Internet for energy products and
services grows. The growth potential and deregulatory environment of the energy
markets have attracted and are anticipated to continue to attract many new
start-ups as well as established businesses from different industries. We expect
competition to continue to increase because our market poses no substantial
barriers to entry. Competition may also increase as a result of industry
consolidation. Increased competition could result in price reductions, reduced
margins, loss of market share, inability to penetrate new markets or to develop
new markets, any of which could have a material and adverse effect on our
business.

         Our current and prospective competitors fall into the following
categories:



                                       12
<PAGE>   15


         o    large and well established distributors of energy measurement,
              monitoring and information products and services, such as Itron
              Corp. and Whisper Communications;

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

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

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

         o    numerous prospective competitors that may offer energy
              information.

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

         o    our responsiveness to customers needs;

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

         o    speed of implementation of new products and services and
              enhancement to existing products and services;

         o    price of competitors' products and services;

         o    ease of use of products and services;

         o    performance and features of products and services;

         o    quality and reliability;

         o    reputation;

         o    quality of customer service and support;

         o    sales and marketing efforts;

         o    our ability to sustain our strategic relationships; and

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

         We cannot assure you that we will be able to compete successfully or to
adequately address the above factors.

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

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

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


                                       13
<PAGE>   16


successfully finance the acquisition. A failure to identify or finance future
acquisitions may impair our growth and adversely affect our business.

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

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

         o    difficulties in retaining key personnel;

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

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

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

         o    changes in management resulting from an alliance or acquisition
              that could impair relationships with employees and customers of
              the acquired company;

         o    risks of entering markets in which we have no or limited direct
              prior experience;

         o    potential disruptions of our ongoing business;

         o    unexpected costs associated with the acquisition; and

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

         We cannot assure you that any acquisition of new businesses or
technology will lead to the successful development or marketing of new or
enhanced products and services.

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

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

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

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

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

         Despite our efforts to protect our intellectual property rights, our
actions may be inadequate to protect these rights or to prevent others from
claiming violations of their proprietary rights. It may be possible for
unauthorized third parties to copy, reverse engineer or otherwise obtain, use or
exploit aspects of our products and services, develop similar



                                       14
<PAGE>   17


technology independently, or otherwise obtain and use information that we regard
as proprietary. We cannot assure you that our competitors will not independently
develop technology similar or superior to our technology or design around our
proprietary rights. We generally require our employees, consultants and
strategic partners to enter into confidentiality and proprietary invention
agreements with us to limit use of, access to, and distribution of our
proprietary technology. Our intellectual property rights with respect to our
PowerSpring may not be viable or of value in the future because of validity,
enforceability and scope or protection of proprietary rights in Internet-related
industries is uncertain and still evolving. In addition, the laws of some
foreign countries may not protect our proprietary rights as fully or in the same
manner as the laws of the United States.

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

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

FROM TIME TO TIME, WE FACE LAWSUITS THAT, IF THEY ARE SUCCESSFUL, COULD
MATERIALLY AND ADVERSELY AFFECT OUR BUSINESS

         We are defendants to a pending action filed in 1993 in Denver District
Court in which the plaintiff is seeking $420,000 in damages plus punitive
damages. We believe the allegations against us are without merit. We have
vigorously contested these allegations, and we have asserted counterclaims
against the plaintiff. In 1997, the Denver District Court entered a summary
judgment in favor of us, but the summary judgment was reversed in February 1999
by the Colorado Court of Appeals. This action is currently scheduled for trial
in the third quarter of 2000. We are also from time to time involved in routine
litigation incidental to our business. Although we do not currently expect any
legal proceedings to have a material and adverse affect on us, we recognize that
the outcome of litigation is inherently uncertain. Therefore, present or future
litigation could materially and adversely affect our business.

WE FACE SOME RISKS THAT ARE INHERENT IN NATURAL GAS OPERATIONS

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

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

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



                                       15
<PAGE>   18


         We also anticipate that the Internet will receive increased attention
and regulation. While there are currently few laws or regulations that apply
directly to commerce and the Internet, new laws and regulations with respect to
the Internet are becoming more prevalent. These laws and regulations may
regulate issues such as user privacy, pricing, intellectual property, federal,
state and local taxation, distribution, characteristics and quality of products
and services, network access, and content. These laws and regulations could
expose us to liability, materially increase our costs of providing our products
and services, decrease the growth and acceptance of the Internet as a means of
commerce, and decrease demand for our products and services being sold over the
Internet. Changes in laws or regulations governing the Internet and Internet
commerce could have a material and adverse effect on our business.

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

         We believe our future success will depend in large part upon our
ability to attract and retain highly qualified technical, managerial, sales and
marketing, finance and operation personnel. In particular, we will need to hire
highly qualified personnel for PowerSpring, including a chief financial officer
and an information technology officer. Competition for qualified personnel is
intense, and we cannot assure you that we will be able to attract and retain
these key employees in the future. We do not maintain key person life insurance
policies for any key members of our management team. The loss of the services of
one or more of our key personnel could have a material adverse effect on our
business. We cannot assure you that we will be able to retain our current key
personnel or that we will be able attract or retain other highly qualified
personnel in the future. We have from time to time in the past experienced, and
we expect to continue to experience in the future, difficulty in hiring and
retaining highly skilled employees with appropriate qualifications. A shortage
in the number of trained technical and marketing personnel could limit our
ability to increase sales of our existing products and services and launch new
product and service offerings, including in our total energy plan and Internet
businesses. We do not have long-term employment agreements with any of our key
personnel, other than with W. Phillip Marcum, our President and Chief Executive
Officer, A. Bradley Gabbard, our Executive Vice President and Chief Financial
Officer, Sidney Hinton, President and Chief Executive Officer of PowerSpring,
and John A. Harpole, Executive Vice President and Chief Operating Officer of
PowerSpring.

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

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

            RISKS RELATED TO THE SECURITIES MARKETS AND THIS OFFERING

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

         As of June 28, 2000, our executive officers, directors and 5% or
greater stockholders beneficially owned, in the aggregate, approximately 61% of
our outstanding common stock, our only class of voting stock, assuming they
exercise or convert all stock options, warrants and other rights exercisable
within 60 days of that date. As a result, these stockholders could, as a
practical matter, be able to exercise significant control over matters requiring
approval by our stockholders, including the election of directors and the
approval of mergers, sales of substantially all of our assets and other
significant corporate transactions. The interests of these stockholders may
differ from the interests of other stockholders. In addition, this concentration
of stock ownership may have the effect of delaying or preventing a change in
control of us.

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

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



                                       16
<PAGE>   19


         On June 28, 2000, 5,166,274 shares of common stock were outstanding. On
the same date, options to purchase 592,774 shares of common stock were
outstanding, and shares acquired upon exercise of these stock options are
eligible for sale on the public market from time to time as they vest. These
stock options generally have exercise prices significantly below the last
reported sale price of the common stock as reported on the cover of this
prospectus. On the same date, 7,000 shares of Series B preferred stock
convertible into 1,179,762 shares of common stock, and warrants other than the
warrants we have called for redemption to purchase 986,620 shares of common
stock, were outstanding. Virtually all shares underlying these warrants and
other rights to purchase common stock are covered by registration rights. The
exercise or conversion of outstanding options, warrants and other rights to
purchase common stock will dilute the remaining ownership of other holders of
common stock. In addition, the sales in the public market of a significant
number of these shares issuable upon the exercise of options, warrants and other
rights, or the perception that these sales could occur, could cause the price of
the common stock to decline.

IF THE MARKET PRICE OF OUR COMMON STOCK DECLINES, THEN WE MAY BE REQUIRED TO
ISSUE ADDITIONAL SHARES OF OUR COMMON STOCK UPON CONVERSION OF THE SERIES B
PREFERRED STOCK, AND HOLDERS OF OUR COMMON STOCK WILL EXPERIENCE IMMEDIATE
DILUTION

         The conversion rate of the Series B preferred stock, and therefore the
number of shares of common stock issuable by us upon conversion of the Series B
preferred stock, will be adjusted if 110% of the average closing bid price of
the common stock for the 30 trading days before December 9, 2000 is less than
the conversion price of the Series B preferred stock then in effect. This
adjustment could require us to issue additional shares of common stock upon the
conversion of the Series B preferred stock and therefore cause the percentage
ownership of holders of our common stock to be diluted substantially. The
conversion price of the Series B preferred stock on the date of this Prospectus
is $5.9334, and each share of Series B preferred stock is initially convertible
into 168.5374 shares of common stock, not including the effect of accrued and
unpaid dividends. If the market price of our common stock decreases
sufficiently, then we may be required to issue a greater number of shares of
common stock, and the percentage ownership of our holders of common stock could
be diluted substantially. The conversion price cannot be reduced by more than
50% of the conversion price in effect on December 9, 2000. Based upon the
initial conversion price and assuming no other adjustments to the conversion
ratio, the maximum number of shares of our common stock that we could be
required to issue upon exercise of the Series B preferred stock due to this
adjustment would be 2,359,524, not including the effect of accrued and unpaid
dividends, if the average closing bid price of our common stock during the
trading period noted above was equal to or less than $2.697. If our average
closing bid price during this period is between $2.697 and $5.394, then the
number of shares of common stock which we will be required to issue upon
conversion of the Series B preferred stock will be proportionately between the
current amount and the maximum amount. In computing this adjustment, any cash,
securities or other assets, other than dividends paid exclusively in cash or
shares of our common stock, will be added to the computation of the average
closing bid price. However, adjustments to the conversion price, or the
existence of accrued and unpaid dividends, before or after this 30 day trading
period, could cause us to issue even a higher number of shares of common stock
upon the conversion of the Series B preferred stock.

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

         Some provisions in our second restated certificate of incorporation,
by-laws and stockholder rights plan, as well as some provisions of Delaware law,
could make it more difficult for a third party to acquire us or discourage a
third party from attempting to acquire us, even if doing so would be beneficial
to you and our other stockholders. These provisions could also limit the price
that investors might be willing to pay in the future for shares of our common
stock. These provisions include:

         o    a classified board of directors of which only approximately 1/3 of
              the total board members are elected at each annual meeting;

         o    authority for our board of directors to issue common stock and
              preferred stock, and to determine the price, voting and other
              rights, preferences, privileges and restrictions of undesignated
              shares of preferred stock, without any vote by or approval of our
              stockholders;

         o    the existence of large amounts of authorized but unissued common
              stock and preferred stock;

WE DO NOT INTEND TO PAY DIVIDENDS ON THE COMMON STOCK, AND YOU MAY NOT
EXPERIENCE A RETURN ON YOUR INVESTMENT IN OUR SECURITIES WITHOUT SELLING YOUR
SHARES

         We have never declared or paid any cash dividends on our common stock.
Therefore, you will not experience a return on your investment in our common
stock without selling your shares since we currently intend on retaining any
future earnings to fund our growth and do not expect to pay dividends in the
foreseeable future.

OUR STOCK PRICE AND ITS TRADING VOLUME FLUCTUATES SIGNIFICANTLY, WHICH COULD
ADVERSELY AFFECT OUR STOCK PRICE AND OUR BUSINESS

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

         o    actual or anticipated variations in our results of operations;

         o    announcements of technological innovations;

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

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

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

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

         o    announcements by us or our competitors of the success or status of
              our business;

         o    general market conditions;

         o    additions or departures of our key personnel;

         o    sales of our common stock by directors, executive officers and
              significant stockholders; and

         o    the gain or loss of significant customer orders.

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

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

WE MAY ISSUE ADDITIONAL PREFERRED STOCK, WHICH COULD DILUTE YOUR INTERESTS

         The terms of the Series B preferred stock do not limit the issuance of
additional series of preferred stock ranking junior to the Series B preferred
stock, but do require the approval of the holders of a majority of the
outstanding shares of



                                       18
<PAGE>   21


Series B preferred stock to issue any stock senior to or on a parity with the
Series B preferred stock. The issuance of additional shares of preferred stock
with dividend, liquidation preference and other rights and privileges ranking
senior to our common stock could dilute the interest of holders of our common
stock.

WE DO NOT CURRENTLY INTEND TO PAY ANY DIVIDENDS ON OUR CAPITAL STOCK, AND EVEN
IF WE DID INTEND TO PAY DIVIDENDS, OUR ABILITY TO PAY DIVIDENDS ON OUR CAPITAL
STOCK IS LIMITED

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

         In addition, our ability to pay dividends on our common stock is
restricted by our current credit facility. Further, if we fail to pay dividends
on the Series B preferred stock, we will be prohibited from paying dividends on
the common stock until all unpaid dividends on the Series B preferred stock have
been paid in full.

         In the future, our board of directors will determine whether we pay
dividends on our common stock subject to the limitations noted above. We do not
presently intend to pay any dividends.

BECAUSE THE WARRANTS HAVE BEEN CALLED FOR REDEMPTION, WARRANT HOLDERS WILL BE
FORCED TO SELL OR REDEEM THEIR WARRANTS ON OR BEFORE THE REDEMPTION DATE

         We have called the warrants for redemption at a redemption price of
$.01 per warrant on August ___, 2000, the redemption date. The warrants will no
longer trade or be exercisable for common stock after the redemption date.
Therefore, holders must either exercise or sell their warrants on or before the
redemption date to avoid receiving the nominal redemption price. This may
require warrant holders to sell or exercise their warrants at a time when they
do not wish to do so, or when the warrant sale or exercise is not in their
personal best interest.


                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

         This prospectus and the documents incorporated by reference in this
prospectus contain forward-looking statements. Forward-looking statements relate
to future events or our future financial performance. You can identify
forward-looking statements by terminology such as "may", "could", "should",
"will", "project", "intend", "continue", "believe", "anticipate", "estimate",
"expect", "plan", "intend", "potential", "scheduled," or the negative of these
terms, or other comparable terminology.

         These forward-looking statements are based on the current plans,
intentions, beliefs and expectations of management as well as assumptions made
by and information currently available to management. You are cautioned not to
place undue reliance on these forward-looking statements. Forward-looking
statements are not guarantees of future performance or events. Forward-looking
statements involve substantial risks and uncertainties. Any or all of these
forward-looking statements could turn out to be wrong. Forward-looking
statements will be affected by inaccurate assumptions we might make or by known
or unknown risks and uncertainties that could cause actual results to differ
materially from those expressed or implied by the forward-looking statements.
These risks and uncertainties include, but are not limited to, the factors
described under "Risk Factors" in this prospectus, as well as other risks and
uncertainties discussed elsewhere in this prospectus, in documents incorporated
by reference in this prospectus and in our other reports and filings with the
SEC. We undertake no duty or obligation to update or revise any forward-looking
statements for any reason, whether as a result of new information, future events
or otherwise.

                                 USE OF PROCEEDS

         The amount of the net proceeds, if any, that we will receive from this
offering is not determinable at this time because the holders of the warrant
have no obligation to exercise the warrants. The proceeds we receive will be due
to the exercise of warrants on or before the redemption date, which will be in
the discretion of the warrant holders. We believe that the number of warrants
that are exercised will depend upon market conditions between the date of this
prospectus and the redemption date, the financial resources of warrant holders,
and other factors outside of our control. If all 839,675 outstanding warrants
called for redemption are exercised, we estimate the net proceeds that we would
receive from the sale of 839,675 shares of common stock we are offering by this
prospectus will be approximately $3,170,000, after deducting estimated
commissions and offering expenses.



                                       19
<PAGE>   22


         We intend to use the net proceeds primarily to fund the development and
expansion of the business of PowerSpring, any remaining fund, will be used for
working capital and general corporate purposes. In addition, a portion of the
proceeds may also be used to acquire or invest in complimentary businesses or
products or to obtain the right to use complimentary technologies, although we
have no currently pending agreement, arrangement, or understanding with respect
to any acquisition or investment. Pending these uses, we intend to invest the
net proceeds of this offering in short-term, investment grade, interest-bearing
securities.

                 TERMS, REDEMPTION AND EXERCISE OF THE WARRANTS

         In September 1998, we distributed the warrants as a dividend to our
stockholders on the basis of one warrant for each four shares of common stock
outstanding on September 10, 1998, the record date for the warrant distribution.
Each warrant is exercisable for one share of common stock at an exercise price
of $4.00 per share until August _____, 2000, the redemption date. We will redeem
any warrants not exercised on or before the redemption date at a redemption
price of $0.01 per warrant. The warrants trade on the Nasdaq SmallCap Market
under the symbol "MTEKW." As of June 28, 2000, 839,675 warrants remained
outstanding.

TERMS OF THE WARRANTS

         The warrants were issued pursuant to the terms and conditions of a
warrant agency agreement between us and American Securities Transfer & Trust
Inc., as warrant agent. The description of the warrants contained in this
prospectus is not complete and is qualified in its entirety by reference to the
warrants agency agreement, which is an exhibit to the registration statement of
which this prospectus is a part and is available upon request.

         The warrants are redeemable at our option at a redemption price of $.01
per warrant at any time, upon at least 30 days prior with notice, if the closing
sale price of the common stock equals or exceeds $6.50 for 20 consecutive
trading days ending within 30 days before the date notice of redemption is
given. In addition, at that time a current registration statement covering the
common stock underlying the warrants must be effective. This prospectus is a
part of an effective registration statement covering the common stock underlying
the warrants. Because these conditions have been met, we have determined to
redeem the warrants at 5:00 p.m., Denver, Colorado time on August __, 2000. The
warrants were originally exercisable, before being called for redemption, until
September 10, 2003.

         All questions as to the validity, form, eligibility, and acceptance of
an exercise of warrants will be determined by us, in our sole discretion, which
determination will be final and binding. We reserve the absolute right to reject
any exercise if it is not in proper form or if the acceptance of the exercise or
the issuance of common stock upon the exercise could be deemed unlawful. We also
reserve the right to waive any defect with regard to any particular exercise. We
are not under any duty to give notification of any defects or irregularities in
exercises, and we will not incur any liability for failure to give any
notification. Warrants will not be deemed exercised until any defects or
irregularities have been cured or waived within the time that we determine.
Warrant exercises with defects or irregularities which have not been cured or
waived will be returned by us to their appropriate holder of the warrants as
soon as practical period.


         The warrants may not be exercisable by any person, and neither this
prospectus nor any warrants shall constitute an offer to sell or solicitation of
an offer to purchase any shares of common stock in any jurisdiction in which
these transactions would be unlawful. We believe that any action required of us
has been taken to permit exercises of the warrants and purchases of the common
stock in all states in which holders of warrants as of the record date reside.
No action has been taken in any jurisdiction outside the United States to permit
offers of sale of the warrants of the common stock. Consequently, we may reject
exercises of warrants by any holder of warrants outside the United States.

REDEMPTION OF THE WARRANTS

         On July ____, 2000, we called for redemption on August ___, 2000, the
redemption date, all of the warrants issued in the 1998 dividend that remain
outstanding as of 5:00 p.m. Denver, Colorado time, on the redemption date at a
redemption price of $.01 per warrant. Each warrant entitles the holder to
purchase one share of our common stock at an exercise price of $4.00 per share.
The right to exercise the warrants expires at 5:00 p.m. Denver, Colorado time on
the redemption date. After the redemption date, warrants cannot be exercised,
and any warrants that remain unexercised after the redemption date will be
redeemed for the redemption price.

         As a result of our election to redeem the warrants, you have the
following three alternatives with respect to your warrants:

         o    You may exercise your warrants. Until 5:00 p.m., Denver, Colorado
              time, on August __, 2000, when the exercise right expires, you may
              exercise your warrants by purchasing shares of our common stock at
              the exercise price of $4.00 per share.



                                       20
<PAGE>   23
         o    You may sell your warrants in the open market. Until 5:00 p.m.,
              Denver, Colorado time on the redemption date, you may sell your
              warrants in the open market through brokers or otherwise. Until
              the redemption date, the warrants will continue to trade on the
              Nasdaq SmallCap Market under the trading symbol "MTEKW". The
              warrants will cease trading after the redemption date.

         o    You may deliver your warrants to be redeemed for cash. After 5:00
              p.m., Denver, Colorado time, on the redemption date, any warrants
              you continue to hold will be redeemed by us at a redemption price
              of $.01 per warrant. All warrants outstanding on or after the
              redemption date will be deemed to be redeemed by us, whether or
              not they have been surrendered for redemption. However, you must
              surrender your warrants to the warrant agent, as discussed below,
              to collect the redemption price.

         You are urged to consult with your own tax, business and other advisors
concerning the tax, business and other consequences of the exercise, sale or
redemption of your warrants.

EXERCISE OF THE WARRANTS

         Warrant holders may exercise their warrants by properly completing and
signing the subscription form on the warrants including, if required, a
signature guarantee from an eligible institution, and mailing or delivering the
warrants to American Securities Transfer & Trust, Inc., the warrant agent,
together with a payment of the aggregate exercise price of the warrants in full
in U.S. dollars, by the holder, to:

                   American Securities Transfer & Trust, Inc.
                     12039 West Alameda Parkway, Suite Z-2
                            Lakewood, Colorado 80228
                           Telephone: (303) 986-5400
                           Facsimile: (303) 986-2444

                                     or to:

                   American Securities Transfer & Trust, Inc.
                                 P.O. Box 1596
                             Denver, CO 80201-1596

A holder may exercise warrants in whole or in part, but no warrants may be
exercised for fractional shares of common stock.

         The exercise price will be considered to have been paid only upon
clearance of the wire transfer, certified or official bank check, bank draft or
money order that is tendered. All funds received by the warrant agent from the
exercise of the warrants will be deposited upon receipt. Pending issuance of
certificates representing shares of common stock, funds received for the
exercise of warrants will be held in a segregated escrow account.

         Once a holder has exercised a warrant, the exercise may not be revoked.
To be accepted, the properly completed warrants and payment with respect to the
exercise price of the warrants must be received by the warrant agent before 5:00
p.m., Denver, Colorado time on August ___, 2000. The instruction accompanying
the warrants should be read carefully and followed in detail. WARRANTS SHOULD BE
SENT WITH PAYMENT TO THE WARRANT AGENT. DO NOT SEND WARRANTS TO US.

         CERTIFICATES REPRESENTING THE SHARES OF COMMON STOCK SUBSCRIBED FOR
WILL BE ISSUED AND DELIVERED AS SOON AS PRACTICABLE AFTER PAYMENT OF THE
EXERCISE PRICE OF THE WARRANTS. HOLDERS OF WARRANTS, WILL NOT HAVE ANY RIGHTS AS
STOCKHOLDERS UNTIL STOCK CERTIFICATES REPRESENTING THE SHARES OF COMMON STOCK
SUBSCRIBED FOR ARE ISSUED TO THEM.

         The risk of method of delivery of all documents and payment is on the
holders of the warrants, not on the warrant agent or us. If the mail is used, it
is recommended that payments be made by registered mail, properly insured,
return receipt requested, and that a sufficient number of days be allowed to
ensure delivery to the warrant agent before the expiration of the warrants.

         Stifel, serving as the dealer manager of this offering, will contact
warrant holders, explain the terms of the proposed redemption to warrant
holders, and solicit holders to exercise their warrants. The dealer manager's
address is: Stifel, Nicolaus & Company, Inc., 1125 17th Street, Suite 1500,
Denver, Colorado 80202, telephone (303) 296-2300. See "Dealer Manager
Arrangement" below.

         Questions relating to the method of exercise should be directed to the
dealer manager or the warrant agent.



                                       21
<PAGE>   24


         THE RIGHT OF HOLDERS TO EXERCISE THESE WARRANTS WILL EXPIRE AT 5:00
P.M., DENVER, COLORADO TIME, ON THE REDEMPTION DATE. ALL WARRANTS NOT PROPERLY
EXERCISED ON OR BEFORE THAT DATE AND TIME WILL BE REDEEMED BY US AT THE
REDEMPTION PRICE. BEFORE THE REDEMPTION DATE, WE WILL DEPOSIT WITH THE WARRANT
AGENT AN AMOUNT SUFFICIENT TO PAY THE REDEMPTION PRICE FOR ALL WARRANTS CALLED
FOR REDEMPTION. AFTER THE REDEMPTION DATE, ALL WARRANT CERTIFICATES EVIDENCING
THE WARRANTS MUST BE DELIVERED TO THE WARRANT AGENT AT THE ADDRESS SHOWN ABOVE
FOR RECEIPT OF THE REDEMPTION PRICE.

         Holders of warrants will realize taxable gain or loss upon a sale or
redemption of the warrants, but will generally not recognize gain or loss upon
exercise of the warrants. Holders of the warrants are urged to consult their tax
advisors as for the federal, state and local tax treatment and consequences
applicable to them upon exercise, sale or redemption of the warrants.

FEDERAL INCOME TAX CONSIDERATIONS

         The following is a summary of the material federal income tax
consequences relevant to the exercise and disposition of the warrants. This
summary is based on the current provisions of the Internal Revenue Code of 1986,
Treasury regulations and judicial and administrative authority, all of which may
change, possibly on a retroactive basis. This summary applies only to investors
who hold our warrants as capital assets, within the meaning of section 1221 of
the Internal Revenue Code. This summary does not discuss the tax consequences to
special classes of investors, including:

         o    brokers or dealers in securities or currencies;

         o    financial institutions;

         o    tax-exempt entities;

         o    life insurance companies;

         o    persons holding warrants as a part of a hedging, short sale or
              conversion transaction or a straddle;

         o    investors whose functional currency is not the United States
              dollar;

         o    persons who hold warrants through partnerships or other
              pass-through entities; or

         o    foreign holders and U.S. expatriates.

         State, local and foreign tax consequences of the warrants are not
summarized.

         We have not requested, and do not intend to request, any rulings from
the Internal Revenue Service concerning the federal tax consequences applicable
to the warrants. You are advised to consult with your own tax advisor regarding
the consequences of acquiring, holding, exercising or disposing of the warrants
in light of current tax laws, your particular investment circumstances, and the
application of state, local and foreign tax laws.

         A warrant holder generally will not recognize gain or loss on exercise
of warrants for cash. The adjusted tax basis of a holder of common stock
acquired on exercise of warrants will be equal to the sum of the holder's
adjusted tax basis in the exercise warrants and the exercise price of the
warrants. The holding period for common stock acquired on exercise of warrants
will begin on the date of exercise.

         If a warrant holder sells or otherwise disposes of the holder's
warrants, the holder will recognize capital gain or loss equal to the difference
between the amount of cash in the fair market value of property received and the
holder's tax basis in the warrants. The gain or loss will be long-term capital
gain or loss if the holding period for the warrants exceeds one year. For
corporate taxpayers, long-term capital gains are taxed at the same rate as
ordinary income. For individual taxpayers, net capital gains - the excess of the
tax payer's net long-term capital gain over his net short-term capital losses -
are taxable at a maximum rate of 20% if the warrants are held for more than one
year.

         If a holder sells or otherwise disposes of common stock acquired upon
exercise of a warrant, the holder will recognize capital gain or loss equal to
the difference between the amount of cash and the fair market value of property
received and the holder's tax basis in the common stock. The gain or loss will
be long-term capital gain or loss if the holder's holding period for this common
stock exceeds one year. The holding period for common stock acquired upon
exercise of warrants commences on the date the warrants are exercised. The tax
rate for long-term capital gains are discussed above under the discussion of tax
considerations of the disposition of warrants. If a holder's warrants are
redeemed by us, the holder will be treated as if he disposed of the warrants for
the redemption price.

         We will not recognize any taxable income or gain upon the exercise or
redemption of the warrants.

         THE FOREGOING DISCUSSION IS FOR GENERAL INFORMATION AND IS NOT TAX
ADVICE. ACCORDINGLY, EACH PROSPECTIVE HOLDER OF WARRANTS OR COMMON STOCK SHOULD
CONSULT ITS TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES TO OF THE



                                       22
<PAGE>   25
WARRANTS, INCLUDING THE APPLICABILITY AND THE EFFECT OF ANY STATE, LOCAL OR
FOREIGN INCOME TAX LAWS, AND ANY RECENT PROSPECTIVE CHANGES IN APPLICABLE TAX
LAWS.

                           DEALER MANAGER ARRANGEMENT

         We have entered into a dealer manager agreement with Stifel, Nicolaus &
Company, Inc., under which Stifel will serve as the dealer manager of this
offering.

         Stifel will provide those services that are customarily performed by
investment banking concerns when acting as a dealer manager for a warrant
redemption. These services include contacting warrant holders, explaining the
terms of the proposed redemption to warrant holders, and soliciting holders to
exercise their warrants. In addition, Stifel may, but is not obligated to, make
a market in the warrants and common stock during the redemption period. In that
connection, Stifel may make purchases and sales of common stock or warrants, in
the open market or otherwise, for long or short account, on such terms as it
deems advisable, all subject to applicable provisions of the Exchange Act. In
effecting any such purchases and sales, Stifel may realize profits or losses
independent of the compensation described below. Stifel has agreed to exercise,
on the redemption date, any warrants that it owns immediately prior to the
effective time of the redemption.

         Under the terms of the dealer manager agreement and in consideration of
Stifel's obligations under that agreement, we have agreed to pay Stifel an
initial fee of $25,000, plus a commission of $0.15 per warrant exercised to the
extent such amount exceeds $25,000. We have agreed to reimburse Stifel for up to
$20,000 of its reasonable out-of-pocket expenses and legal fees, in connection
with the transactions contemplated by the dealer manager agreement. We have
agreed to indemnify Stifel against liabilities, including liabilities under the
Securities Act, or to contribute to payments which Stifel may be required to
make relating to those liabilities.

         Stifel has from time to time in recent years performed various
investment banking and other financial advisory services for us, for which it
has received customary compensation. These services have included rendering a
fairness opinion to us in connection with the units private placement.


                             SELLING SECURITYHOLDER

         This prospectus also covers the resale of up to 136,263 of the warrants
called for redemption by a selling securityholder, American Meter Company. The
address for American Meter is 300 Welsh Road, Horsham, Pennsylvania



                                       23
<PAGE>   26


19044. As of June 28, 2000, the selling securityholder beneficially owned
461,317 shares of common stock, consisting of 325,054 shares of common stock and
136,263 shares issuable upon exercise of warrants held by the selling
securityholder, representing 8.7% of the number of outstanding shares of common
stock on that date plus the number of warrants owned by the selling
securityholder.

         On May 4, 1998, through Metretek Florida we acquired assets from the
selling securityholder. In consideration for those assets, we issued to the
selling securityholder 439,560 shares of common stock, a $600,000 convertible
promissory note and $1.3 million in cash. We issued to the selling
securityholder 109,890 warrants in the 1998 warrant distribution, and 105,495
shares of common stock and 26,373 warrants upon conversion of the convertible
promissory note. Before the date of this prospectus, the selling securityholder
sold 220,000 shares of common stock. Harry I. Skilton, the President and Chief
Executive Officer of the selling securityholder, was a member of our board of
directors from May 4, 1998, the date of the acquisition, until June 7, 2000. Mr.
Skilton beneficially owned 14,386 shares of common stock, including 11,261 that
may be acquired by Mr. Skilton upon the current exercisable stock options and
625 shares that may be acquired by Mr. Skilton upon the exercise of currently
exercisable warrants. The shares of common stock beneficially owned by Mr.
Skilton had not been included in the beneficial ownership of the selling
securityholder.

         In connection with the acquisition of assets from the selling
securityholder, we granted to the selling securityholder registration rights.
Under those registration rights, we have registered the resale of the warrants
under this prospectus. We cannot estimate the number of warrants that the
selling securityholder will beneficially own upon completion of this offering,
because the selling securityholder may sell all, part or none of the warrants
under this prospectus and because there are currently no agreements,
arrangements or understandings with respect to the sale of any the warrants
offered by the selling securityholder under this prospectus.

         On May 4, 1998, in connection with our acquisition of assets from
American Meter, we and Metretek Florida entered into agreements relating to the
acquisition and ongoing relationships with American Meter, including an asset
purchase agreement, a promissory note, and a noncompete agreement. Metretek
Florida also entered into a license agreement with American Meter, for the
license by American Meter to Metretek of operating software, and the
development, manufacture and sale by Metretek Florida to American Meter of
electronic components and related equipment pertaining to electronic temperature
and pressure correction to be embedded within new rotary and turbine meters of
American Meter. The license agreement also grants to American Meter and its
affiliates the right to sell Metretek Florida products in the United States and
Canada at agreed-upon prices. After the acquisition, Metretek Florida and
American Meter entered into an international sales agreement, under which
American Meter and its affiliates have the non-exclusive right to sell Metretek
Florida products internationally. During fiscal 1998 and 1999, we recorded
revenues of approximately $522,000 and $593,000 with respect to sales to
American Meter under the license agreement and the international sales
agreement. The terms of the acquisition agreement, the license agreement and the
international sales agreement were the result of arms-length negotiations
between the parties.

         The selling securityholder may from time to time offer and sell the
warrants under this prospectus. References in this prospectus to the selling
securityholder include American Meter and any donees, pledgees, transferees or
other successors-in-interest selling shares received from the selling
securityholder as a gift, pledge, partnership distribution or other
non-sale-related transfer after the date of this prospectus. The selling
securityholder will act independently of us in making decisions with respect to
the timing, manner and size of each sale of the shares.

         The selling securityholder may sell the warrants offered under this
prospectus on the Nasdaq National Market, on any other stock exchange or stock
market on which the shares may from time to time be traded, in the
over-the-counter market, in negotiated transactions, in underwritten
transactions or otherwise, at market prices prevailing at the time of sale, at
prices related to the then prevailing market prices, at negotiated prices, or at
fixed prices, in one or more of the following transactions:

         o    a block trade in which the broker-dealer engaged will attempt to
              sell the warrants as agent, but may position and resell a portion
              of the block as principal to facilitate the transaction;

         o    a purchase by a broker-dealer as principal and resale by the
              broker-dealer for its own account under this prospectus;

         o    an exchange distribution under the rules of the exchange;

         o    ordinary brokerage transactions and transactions in which the
              broker solicits purchasers;

         o    privately negotiated transactions;

         o    through the writing of options on the warrants, whether or not the
              options are listed on an options exchange;

         o    pledges to secure debts and other obligations;



                                       24
<PAGE>   27


         o    short sales;

         o    broker-dealers may agree with the selling securityholder to sell a
              specified number of warrants at a stipulated price per share; or

         o    any other method permitted by applicable law.

         The selling securityholder may effect sales by selling the warrants
directly to purchasers or to or through underwriters or broker-dealers, acting
as principal or agent. In effecting sales, underwriters or broker-dealers
engaged by the selling securityholders may arrange for other broker-dealers to
participate in the resales. The selling securityholder has advised us that, as
of the date of this prospectus, it has not entered into any agreements,
understandings or arrangements with any underwriters or broker-dealers regarding
the sale of the warrants offered under this prospectus. There is no underwriter
or coordinating broker acting in connection with the proposed sale of warrants
by the selling securityholder.

         Broker-dealers or agents may receive compensation in the form of
commissions, discounts or concessions from the selling securityholder.
Broker-dealers or agents may also receive compensation from the purchasers of
the warrants for whom they act as agents or to whom they sell as principal, or
both. Compensation as to a particular broker-dealer might be in excess of
customary commissions and will be in amounts to be negotiated in connection with
the sale. The selling securityholder and any broker-dealers or agents that
participate in the distribution of the warrants may be deemed to be
"underwriters" within the meaning of the Securities Act in connection with these
sales. Accordingly, any commission, discount or concession received by them and
any profit on the resale of the warrants purchased by them may be deemed to be
underwriting discounts or commissions under the Securities Act. Because the
selling securityholder may be deemed to be an underwriter under the Securities
Act, the selling securityholder will be required to comply with the prospectus
delivery requirements of the Securities Act.

         The selling securityholder may enter into hedging transactions with
broker-dealers or other financial institutions in connection with distributions
of the warrants or otherwise. In connection with these transactions,
broker-dealers or other financial institutions may engage in short sales of the
warrants offered under this prospectus in the course of hedging the positions
they assume with selling securityholder. The selling securityholder also may
sell warrants short and redeliver the shares offered under this prospectus to
close out its short position. The selling securityholder may also enter into
options or other transactions with broker-dealers or other financial
institutions which require the delivery to the broker-dealers or other financial
institutions of the warrants offered under this prospectus. The broker-dealer
may then resell or otherwise transfer these warrants under this prospectus as it
may be amended or supplemented to reflect this transaction. The selling
securityholder also may loan or pledge the warrants offered under this
prospectus to a broker-dealer or other financial institution. The broker-dealer
or other financial institution may sell the warrants so loaned, or upon a
default the broker-dealer or other financial institution may sell the pledged
warrants under this prospectus.

         In addition, any warrants offered under this prospectus that qualify
for sale under Rule 144 under the Securities Act may be sold by the selling
securityholder under Rule 144 rather than under this prospectus.

         The warrants will be sold only through registered or licensed brokers
or dealers if required by applicable state securities laws. In addition, in some
states the warrants may not be sold unless they have been registered or
qualified for sale in the applicable state or an exemption from the registration
or qualification requirement is available and is complied with.

         Under applicable rules and regulations under the Exchange Act, any
person engaged in a distribution of the warrants offered under this prospectus
may be limited in its ability to engage in market activities with respect to
these warrants. The selling securityholder will be required to comply with the
applicable provisions of the Exchange Act and the associated rules and
regulations under the Exchange Act, including the anti-manipulation provisions
of Regulation M, which provisions may restrict activities of the selling
securityholders and limit the timing of purchases and sales of shares by the
selling securityholder. Furthermore, under Regulation M under the Exchange Act,
any person engaged in the distribution of the warrants may not simultaneously
engage in market-making activities with respect to the particular warrants being
distributed for specific periods before the commencement of the distribution.
All of the foregoing may affect the marketability of the securities and the
ability of any person to engage in market-making activities with respect to the
warrants.

         Upon being notified by the selling securityholder that any material
arrangement has been entered into with a broker-dealer for the sale of warrants
through a block trade, special offering, underwritten offering, exchange
distribution or secondary distribution or a purchase by a broker or dealer, we
will file a supplement to this prospectus, if required, under Rule 424(b) under
the Securities Act, disclosing:



                                       25
<PAGE>   28


         o    the name of the selling securityholder and of the participating
              broker-dealer(s);

         o    the number of warrants involved;

         o    the price at which the warrants were sold;

         o    the commissions paid or discounts or concessions allowed to the
              broker-dealer(s), where applicable;

         o    that the broker-dealer(s) did not conduct any investigation to
              verify the information set out or incorporated by reference in
              this prospectus; and

         o    other facts material to the transaction.

         In addition, upon being notified by the selling securityholder that a
donee, pledgee, transferee or other successor-in-interest intends to sell more
than 500 warrants, we will file a supplement to this prospectus. Any prospectus
supplement may also add, update or change any information contained in this
prospectus.

         We will pay all expenses related to the registration of the sale of the
warrants offered under this prospectus by the selling securityholder. The
selling securityholder will pay all commissions, discounts, concessions and
other compensation and selling expenses attributable to the sale of the
warrants. We have agreed to indemnify the selling securityholder against
liabilities related to the registration of the warrants, including liabilities
arising under the Securities Act, or to contribute to payments the selling
securityholders may be required to make in respect of these liabilities. The
selling securityholder may agree to indemnify any broker-dealer or agent that
participates in transactions involving sales of the warrants against liabilities
related to the offer and sale of the warrants, including liabilities arising
under the Securities Act, or to contribute to payments a broker-dealer or agent
may be required to make in respect of these liabilities.

         We cannot assure you that the selling securityholder will sell all or
any of the warrants offered under this prospectus.

                          DESCRIPTION OF CAPITAL STOCK

         Our authorized capital stock consists of 25,000,000 shares of common
stock, par value $.01 per share, and 3,500,000 shares of preferred stock, par
value $.01 per share. Of our preferred stock, 1,000,000 shares are designated as
Series B preferred stock, 500,000 shares are designated as Series C preferred
stock, and the remaining 2,000,000 shares are undesignated.

         As of June 28, 2000, the following were outstanding:

         o    5,166,274 shares of common stock;

         o    7,000 shares of Series B preferred stock, convertible into
              approximately 1,179,762 shares of common stock;

         o    options to purchase an aggregate of 592,774 shares of common
              stock; and

         o    warrants to purchase an aggregate of 986,620 shares of common
              stock, excluding the warrants we have called for redemption.

         The following summary of our capital stock is not intended to be
complete and is subject to, and qualified in its entirety by, reference to our
second restated certificate and our by-laws and the provisions of applicable
law. Our second restated certificate and our amended and restated by-laws are
exhibits to the registration statement of which the prospectus is a part.

COMMON STOCK

         The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders, other than matters to be voted on
solely by one or more series of preferred stock, voting separately. The holders
of common stock are not entitled to cumulative voting rights in the election of
directors. Accordingly, the holders of a majority of the shares of the common
stock entitled to vote in any election of directors may elect all of the
directors standing for election, other than those directors who may be elected
only by holders of a series of preferred stock, voting separately. Depending
upon any preferential dividend rights that may be applicable to any outstanding
preferred stock, the holders of common stock are entitled to receive ratably
those dividends, if any, as may be declared from time to time by the board of
directors out of funds legally available therefor. In the event of our
liquidation, dissolution or winding up, the holders of common stock are entitled
to share ratably in all assets remaining after payment of all debts and other
liabilities, depending upon the preferential distribution rights of shares of
preferred stock, if any,



                                       26
<PAGE>   29


then outstanding. The holders of our common stock have no preemptive, conversion
or other subscription rights to purchase any shares of our capital stock. There
are no redemption or sinking fund provisions applicable to the common stock. All
outstanding shares of common stock are fully paid and nonassessable. The rights
of holders of common stock depend upon, and might be adversely affected by, the
rights of any series of preferred stock which we have issued or may issue in the
future.

PREFERRED STOCK

         AUTHORIZATION

         Under our second restated certificate, the board of directors has the
authority, without further action by the stockholders, other than the approval
of holders of Series B preferred stock, if any, described in "-- Series B
Preferred Stock - Voting Rights", to issue shares of preferred stock in one or
more series and to establish the designations, powers, preferences and relative,
participating, optional or special rights, and any qualifications, limitations
or restrictions, including voting rights, dividend rates, conversion rights,
terms of redemption and liquidation preferences applicable to the shares of each
series, any or all of which may be greater than the rights of the common stock.
Under this authority, the board of directors can issue shares of preferred stock
with voting, conversion or other rights that could adversely affect the voting
power and other rights of the holders of common stock. This ability of the board
of directors to issue preferred stock could have the effect of delaying,
deferring or preventing a change of control. Additionally, the issuance of
preferred stock may have the effect of decreasing the price of the common stock
and may adversely affect the voting and other rights of the holders of common
stock. Except for the issuance of the Series C preferred stock under the terms
of our rights agreement, we have no present plans to issue any shares of
preferred stock.

         SERIES B PREFERRED STOCK

         The terms of the Series B preferred stock are described below under
"-- Series B Preferred Stock."

         SERIES C PREFERRED STOCK

         The Series C preferred stock is to be issued only in connection with
our rights agreement described below under "-- Rights Agreement." Each share of
Series C preferred stock has the following material terms:

         o    cumulative quarterly dividends in preference to the holders of
              common stock equal to the greater of $4.00 per share or 25 times
              the dividend paid per share to holders of common stock;

         o    25 votes per share; and

         o    a preference on liquidation equal to the greater of $16 per share
              or 25 times the amount payable per share to the holders of common
              stock.

SERIES B PREFERRED STOCK

         DIVIDENDS

         Holders of shares of Series B preferred stock are entitled to receive,
when, as and if declared by our board of directors out of our funds which are
legally available for payment, cumulative dividends in cash at the annual rate
of 8% of the initial liquidation preference of $1,000 per share of Series B
preferred stock. This is equivalent to $80.00 per share annually.

         So long as at least 1,000 shares of Series B preferred stock are
outstanding and cumulative dividends on the Series B preferred stock have not
been paid in full, we will not:

         o    pay or declare any dividend or make any distribution on any of our
              common stock or any other class of our capital stock ranking
              junior to or on a parity with the Series B preferred stock as to
              dividend, liquidation or redemption rights; or

         o    purchase, redeem or acquire, or pay, set aside or make available
              for a sinking fund any monies to purchase, redeem or acquire, any
              shares of our common stock or other class of our capital stock
              ranking junior to or on a parity with the Series B preferred stock
              as to dividend, liquidation or redemption rights.

         In addition to the 8% cumulative dividends discussed above, holders of
Series B preferred stock are entitled to receive dividends out of funds legally
available for payment of dividends at the times and in the amounts as our board
of directors, in its sole discretion, may determine. We will not declare or pay
any dividend in cash or common stock on any



                                       27
<PAGE>   30


shares of common stock unless at the same time we declare or pay the same
dividend on the Series B preferred stock on the basis of the number of shares of
common stock into the Series B preferred stock held is then convertible.

         REDEMPTION

         Mandatory redemption. On December 9, 2004, depending upon the legal
availability of funds, we will be required to redeem all of the outstanding
shares of the Series B preferred stock at a redemption price, payable in cash,
equal to the initial liquidation preference plus accumulated and unpaid
dividends, if any, to the date of redemption. We will not be required to make
sinking fund payments with respect to the Series B preferred stock.

         Redemption upon extraordinary transactions. The holders of not less
than a majority of the outstanding shares of Series B preferred stock may elect
to either have the Series B preferred stock redeemed in connection with, or to
participate in, any of the following "extraordinary transactions":

         o    a merger or consolidation of us with or into another corporation,
              unless a majority of the outstanding voting power of the surviving
              or consolidated corporation is held by our stockholders
              immediately before that transaction;

         o    the sale or transfer of all or substantially all of our properties
              and assets;

         o    any purchase by any party or group of affiliated parties of shares
              of our capital stock, through a negotiated stock purchase or a
              tender for our shares, resulting in a party or group of affiliated
              parties that did not beneficially own a majority of our voting
              power immediately before the purchase beneficially owning a
              majority of our voting power immediately after the purchase; or

         o    our repurchase of shares representing a majority of our voting
              power immediately before the redemption.

         Unless the holders of Series B preferred stock have elected to convert
their shares of Series B preferred stock into common stock, then as a condition
to any extraordinary transaction we must either:

         o    redeem all outstanding shares of Series B preferred stock at a
              redemption price equal to the initial liquidation preference plus
              accumulated and unpaid dividends, if any, payable in cash or, at
              the election of the holders of the Series B preferred stock,
              payable in the same form of consideration as is paid to the
              holders of common stock in the extraordinary transaction, if the
              holders of Series B preferred stock elect to have their shares
              redeemed; or

         o    take those actions as are sufficient to facilitate the
              participation of the holders of the Series B preferred stock in
              the extraordinary transaction permitting them to receive, as a
              preferential amount, the amount they would have received upon
              redemption either in cash, or at the election of the holders of
              Series B preferred stock, in the same form of consideration as is
              paid to the holders of common stock in the extraordinary
              transaction, if the holders of Series B preferred stock elect to
              participate in the extraordinary transaction.

         A sale of substantially all of our assets means a sale or other
disposition other than in the ordinary course of business of more than 75% of
our assets, based upon the book value or fair market value of our assets,
determined on a consolidated basis under generally accepted accounting
principles.

         Upon any redemption due to an extraordinary transaction, if the holders
of the Series B preferred stock, by converting their shares into common stock
before the extraordinary transaction, would receive an amount greater than the
redemption price payable to them if they do not convert their shares into common
stock, then they will be entitled, upon an election by holders of a majority of
the outstanding shares of the Series B preferred stock, to receive the greater
amount in the extraordinary transaction. We are not permitted to participate in
any extraordinary transaction or to make or agree to make any payments to
holders of common stock or any other shares of our capital stock ranking junior
to the Series B preferred stock unless the holders of the Series B preferred
stock have received the full preferential amount to which they are entitled in
the extraordinary transaction.

         Optional redemption. On or after December 9, 2000, if the market price
of our common stock equals or exceeds 200% of the conversion price of the Series
B preferred stock then in effect for at least 20 trading days within any 30
consecutive trading day period, we will have the right to redeem the Series B
preferred stock. The current conversion price is $5.9334 per share of common
stock. If we redeem the Series B preferred stock, the redemption price will be
equal to the initial liquidation preference, plus accumulated and unpaid
dividends, if any, to the redemption date. We will give at least 30 days written
notice to the holders of Series B preferred stock before we redeem the Series B
preferred stock, and the notice must be given within 30 days after the 30
consecutive trading day period referred to above.



                                       28
<PAGE>   31


         Other redemption provisions. If, on any date we are obligated to redeem
the Series B preferred stock, we are prohibited under Delaware law from
redeeming all outstanding shares of the Series B preferred stock, then we will
redeem as many shares as we are permitted under Delaware law on a pro rata basis
among the holders of the Series B preferred stock, and we will take any
necessary or appropriate action to remove any impediments on our ability to
redeem the remaining shares. If we are still unable to redeem all shares of
Series B preferred stock, then the dividend rate on the unredeemed shares will
increase to an annual rate of 10%, and will increase by an additional 0.5%
annual rate at the end of each six month period, up to a maximum annual rate of
15%, until all outstanding shares of Series B preferred stock have been redeemed
and the redemption price has been paid in full.

         LIQUIDATION PREFERENCE

         Upon our voluntary or involuntary liquidation, dissolution or
winding-up, each holder of Series B preferred stock is entitled to be paid, out
of our assets available for distribution to stockholders, an amount equal to the
initial liquidation preference of $1,000 per share of Series B preferred stock
held by the holder, plus accumulated and unpaid dividends to the date fixed for
liquidation, dissolution or winding up, before any distribution is made on our
common stock or any other class of our capital stock that is junior to the
Series B preferred stock as to liquidation rights. If, upon our voluntary or
involuntary liquidation, dissolution or winding-up, there are not sufficient
assets to pay all amounts payable with respect to the Series B preferred stock,
then the holders of the Series B preferred stock will share ratably in any
distribution of our assets in proportion to the respective preferential amount
to which they are entitled. In addition, if, upon our voluntary or involuntary
liquidation, dissolution or winding-up, the holders of Series B preferred stock
would have received more than the liquidation preference referred to above if
they had converted their shares into common stock immediately before the
liquidation, dissolution or winding up, then the holders of Series B preferred
stock will receive the greater amount.

         VOTING RIGHTS

         The holders of Series B preferred stock have no voting rights, except
as required under Delaware law or as provided in the provisions of Article
Fourth of our second restated certificate governing the Series B preferred
stock.

         As long as at least 2,000 shares of Series B preferred stock are
outstanding, then the holders of the outstanding shares of Series B preferred
stock, voting together as a separate class, are entitled to elect one member of
our board of directors. On March 13, 2000, the holders of Series B preferred
stock elected Kevin P. Collins as their designated director.

         If we fail to redeem all of the Series B preferred stock when we are
required to do so by the terms of the Series B preferred stock, then the holders
of the outstanding shares of Series B preferred stock, voting together as a
separate class, will be entitled to elect to serve on our board of directors
that number of directors constituting a majority of the members of our board of
directors, and the number of members of our board of directors will be
automatically increased by that number. These special voting rights of the
Series B preferred stock will continue until we have paid the redemption price
of all outstanding shares of Series B preferred stock in full, including any
interest due as a result of our failure to pay the redemption price, at which
time the terms of any directors elected by the holders of Series B preferred
stock under these special voting rights will terminate and the number of members
of our board of directors will be immediately decreased by that number.

         So long as at least 1,000 shares of Series B preferred stock remain
outstanding, we may not, without the consent of at least a majority of the then
outstanding shares of Series B preferred stock:

         o    merge, consolidate, recapitalize, reorganize or engage in any like
              transaction;

         o    liquidate or dissolve;

         o    sell or transfer all or substantially all of our consolidated
              properties or assets;

         o    dispose of assets for consideration in excess of $1,000,000
              without the approval of our board of directors; or

         o    borrow money, except up to $3,000,000 under our primary credit
              agreement.

         In addition, as long as any shares of Series B preferred stock are
outstanding, we may not, without the consent of the holders of at least a
majority of the then outstanding shares of Series B preferred stock:



                                       29
<PAGE>   32


         o    issue any equity security, or any securities exchangeable for or
              convertible into equity securities or measured by our earnings or
              profit, other than the Series C preferred stock, that rank senior
              to or parity with the Series B preferred stock as to liquidation,
              dividend and redemption rights;

         o    redeem, repurchase or otherwise acquire for value any of our
              equity securities other than the Series B preferred stock under
              its terms or up to 250,000 shares of common stock under
              restriction agreements with our employees, officers, directors,
              consultants or other persons performing services for us; or

         o    amend our certificate of incorporation, by-laws or other charter
              documents or those of any of our subsidiaries.

         CONVERSION RIGHTS

         Each share of Series B preferred stock are convertible, in whole or in
part, at the option of the holder, into that number of shares of common stock
equal to the "conversion value," which is $1,000 plus accumulated and unpaid
dividends on the share, divided by the then applicable "conversion price" of the
Series B preferred stock.

         The initial conversion price of the Series B preferred stock is $5.9334
per share of common stock. At an initial conversion value of $1,000, each share
of Series B preferred stock is initially convertible into 168.5374 shares of
common stock. The conversion price will be adjusted if any of the following
events occurs:

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

         o    any dividend or distribution payable in shares of the common
              stock;

         o    any subdivision or split-up of the common stock;

         o    any combination or reverse split of the common stock;

         o    any issuance, sale or exchange of shares of common stock at a
              price per share of common stock less than the greater of the
              "market price" of the common stock or the conversion price in
              effect immediately before the issuance, sale or exchange of the
              shares, excluding the following "excluded shares":

              (1)    1,211,236 shares and options issued or issuable to our
                     officers, directors and employees or issuable upon the
                     exercise of options or other rights issued to them under
                     our stock option, stock purchase and related employee
                     plans,

              (2)    up to 1,555,150 shares issuable upon the exercise of
                     warrants or other rights we issued before December 9, 1999,
                     or

              (3)    any securities issuable upon conversion of the Series B
                     preferred stock or exercise of unit warrants.

         o    any issuance of options, warrants or rights to subscribe for
              shares of common stock, or securities convertible into or
              exchangeable for shares of common stock, at a purchase price less
              than the greater of the then current market price or the
              conversion price then in effect, other than options or warrants
              for excluded shares;

         o    any distribution to all holders of our common stock of evidences
              of indebtedness, shares of our capital stock other than common
              stock, other securities, cash or assets, excluding any options,
              rights or warrants for which an adjustment to the conversion price
              referred to above is applicable and any distributions paid
              exclusively in cash or in common stock;

         o    any reclassification or capital reorganization of the common
              stock; and

         o    any merger, consolidation or sale of all or substantially all of
              our properties and assets.



                                       30
<PAGE>   33


         If the conversion price of the Series B preferred stock is adjusted to
the reset price on December 9, 2000, then the holders of Series B preferred
stock are not permitted, for a period of 90 days after that adjustment, to sell,
pledge or transfer, one capital share, or for a period of 30 days after the
adjustment, to purchase any of our common stock to cover any "short" purchases,
although during the post-adjustment period they can convert their Series B
preferred stock or exercise their warrants.

         The "market price" of the common stock for any date means the last sale
price of the common stock on that date or, if there was no sale on that date,
the average of the closing bid and sale price of the common stock on that date,
as reported on the Nasdaq National Market as long as the common stock is traded
on the Nasdaq National Market. No adjustment in the conversion price will be
required to be made until a cumulative adjustment amounting to 1% or more of the
conversion price as last adjusted is required. Fractional shares of common stock
will not be issued upon conversion but, instead, we will round the applicable
number of shares of common stock to be issued upon conversion to the nearest
whole number of shares.

WARRANTS CALLED FOR REDEMPTION

         In September 1998, we distributed the warrants as a dividend to our
stockholders on the basis of one warrant for each four shares of common stock
outstanding on September 10, 1998, the record date for the warrant distribution.
The terms of the warrant are described in "Terms, Redemption and Exercise of the
Warrants -- Terms of Warrants."

OTHER WARRANTS

         In the units private placement we issued 700,000 unit warrants. Each
unit warrant entitles the holder to purchase one share of common stock at an
initial exercise price of $6.7425. The initial exercise price of the unit
warrants will be reset on December 9, 2000 to 125% of the average closing bid
price of the common stock for the 30 trading days immediately preceding this
date, if this computed amount is less than the exercise price of the unit
warrants then in effect. The exercise price may also be adjusted under the
anti-dilution provisions of the unit warrants, which are substantially the same
as the anti-dilution provisions of the Series B preferred stock described under
"--Series B Preferred Stock - Conversion Rights" above. The unit warrants can be
exercised at any time until December 9, 2004. Instead of paying the exercise
price in cash, holders may exercise their unit warrants by delivering to us
shares of common stock with a fair market value equal to the exercise price.
Alternatively, holders of unit warrants may make a "cashless" exercise of the
unit warrants and receive, upon exercise and without making any payments of
cash, common stock or any other asset, a "net" number of shares of common stock
determined by a formula based on the amount the trading price of the common
stock exceeds the exercise price then in effect.

         When we acquired Metretek Florida, we issued warrants to purchase our
common stock to the holders of then outstanding warrants to purchase Metretek
Florida capital stock. As of June 28, 2000, warrants to purchase an aggregate of
36,620 shares of common stock were outstanding, with expiration dates through
2004 and with exercise prices ranging from $44.48 to $88.96 per share. The
shares of common stock issuable upon exercise of these warrants cannot be resold
unless the resale is registered under the Securities Act and under applicable
state securities laws made under available exemption therefrom. The holders of
these warrants have the right, under some circumstances, to require us to
register the shares of common stock issuable upon exercise of these warrants
under the Securities Act and applicable state securities laws.

         As of June 28, 2000, in addition to the warrants described above,
warrants to purchase 250,000 shares of common stock at exercise prices ranging
from $2.47 to $14.50 per share were outstanding. Warrants exercisable for
150,000 shares of common stock are currently exercisable, and the remainder of
the warrants will become exercisable through 2001. These warrants expire between
2002 and 2004. We issued these warrants for consulting and other advisory
services the warrant holders rendered to us.

         We are not redeeming any warrants other than the warrants issued in the
1998 warrant distribution. The shares of common stock issuable upon the exercise
of the other warrants described above cannot be resold unless the resale is
registered under the Securities Act and under applicable state securities laws
or is made under available exemptions from the registration requirements. The
holders of these other warrants can require us to register their resale of the
shares of common stock that are issuable upon exercise of these warrants if we
register other securities. These registration rights are described below under
"-- Registration Rights."

REGISTRATION RIGHTS

         Under the terms of the registration rights agreement among us and the
unit purchasers in the units private placement, we have registered under the
Securities Act the resale of the shares of common stock and Series B preferred
stock acquired by the unit purchasers in the units private placement and the
shares of common stock issuable upon exercise of the unit warrants and upon
conversion of the Series B preferred stock.



                                       31
<PAGE>   34


         In connection with the acquisition of assets from American Meter, we
granted to American Meter the right to demand, on one occasion, beginning May 4,
2000, that we file a registration statement for the registration of all or any
portion of these shares under the Securities Act. In addition, American Meter is
entitled to piggy-back registration rights in connection with any registration
by us of securities for any account or the account of other stockholders.
American Meter's demand registration rights terminate on the earlier of May 4,
2006 or 90 days after American Meter's ownership of these shares falls below 10%
of all outstanding common stock. We have registered the resale of all shares of
common stock owned by American Meter or underlying the warrants owned by
American Meter.

         The holders of the other warrants described above are entitled to
piggy-back registration rights in connection with any registration by us of
securities for our own account or for the account of our security holders.
Generally, if we propose to register any securities under the Securities Act, we
are required to give these securityholders notice of the registration and to
include their shares in the registration statement, although these rights may be
cut-back in underwritten offerings. The resale of the shares of common stock
underlying these other warrants have also been previously registered.

         We are generally required to bear all expenses of all demand and
piggy-back registrations, except broker-dealer and underwriting discounts and
commissions and other selling expenses. We have also agreed to indemnify some of
these securityholders from liability involved in these registrations.

ANTI-TAKEOVER EFFECTS OF OUR SECOND RESTATED CERTIFICATE AND BY-LAW PROVISIONS

         Provisions of our second restated certificate and our by-laws, which
are summarized below, may be deemed to have anti-takeover effects and may delay,
defer or prevent a tender offer or takeover attempt that a stockholder might
consider in its best interest, including those attempts that might result in a
premium over the market price for the shares held by stockholders.

         Related person business combinations

         Under our second restated certificate, "business combinations" with
"related persons", which are persons who beneficially own 20% or more of our
voting power, and their affiliates and associates, must be approved by the
affirmative vote of the holders of not less than 80% of our outstanding voting
stock, and the affirmative vote of the holders of not less than 67% of our
outstanding voting stock held by stockholders other than related persons. This
super-majority voting requirement does not apply to a business combination
either in which the cash or the fair market value of the other consideration to
be received per share by stockholders in the business combination is not less
than the highest per share price paid by the related person in acquiring any of
its holdings of our common stock, or which has been approved in advance by
two-thirds of our continuing directors.

         Super-majority voting provisions

         Under our second restated certificate, the affirmative vote of the
holders of not less than 80% of our outstanding voting stock is required to
approve fundamental corporate actions including mergers, consolidations,
combinations, dissolutions, and sales of all or substantially all our assets,
unless these actions are approved by two-thirds of our board of directors. Our
second restated certificate also requires the affirmative vote of the holders of
not less than 80% of our outstanding voting shares to amend or repeal any
provision of our second restated certificate or our by-laws, if it is required
or demanded that the stockholders vote on the amendment or repeal, unless the
amendment or repeal is approved by two-thirds of our board of directors.

         Classified board of directors

         Our board of directors is divided into three classes, with the
directors of each class being elected for three-year terms at the annual meeting
of stockholders. In addition, under Delaware law, members of our board of
directors may be removed only for cause. These provisions, when coupled with the
provision of our second restated certificate authorizing the board of directors
to fill vacant directorships, may delay a stockholder from removing incumbent
directors and simultaneously gaining control of the board of directors by
filling vacancies created by the removal with its own nominees.

         Stockholder action; special meetings of stockholders

         Our second restated certificate eliminates the ability of stockholders
to act by written consent. Our by-laws further provide that special meetings of
our stockholders may be called only by our President or by our board of
directors.

         Advance notice requirements for stockholder proposals and directors
         nominations

         Our by-laws provide that stockholders seeking to bring business before
an annual meeting of stockholders, or to nominate candidates for election as
directors at an annual meeting of stockholders, must provide timely notice in
writing. To be timely, a stockholder's notice must be received at our principal
executive offices not less than 45 days nor more than 120 days before the
anniversary date on which we first mailed our proxy materials for the
immediately preceding



                                       32
<PAGE>   35


annual meeting of stockholders. If the annual meeting is called for a date that
is not within 30 days before or after the anniversary date of the preceding
annual meeting, notice from the stockholder must be received:

         o    not earlier than 180 days before to the annual meeting of
              stockholders; and

         o    not later than the later of 75 days before the annual meeting of
              stockholders or the tenth day following the date on which we
              publicly announce the date of the annual meeting.

         Our by-laws also specify the requirements of the form and content of a
stockholder's notice. These provisions may preclude stockholders from bringing
matters before an annual meeting of stockholders or from making nominations for
directors at an annual meeting of stockholders.

         Authorized but unissued shares of our capital stock

         All authorized but unissued shares of our common stock and preferred
stock are available for future issuance without stockholder approval, except for
approvals required by stock exchange rules and, in the case of the issuance of
preferred stock, the terms of the Series B preferred stock as described in
"Description of the Series B Preferred Stock -Voting Rights." These additional
shares may be utilized for a variety of corporate purposes, including future
public offerings to raise additional capital, corporate acquisitions and
employee benefit plans. The existence of authorized but unissued shares of
common stock and preferred stock could render more difficult or discourage an
attempt to obtain control of us by means of a proxy contest, tender offer,
merger or otherwise.

DELAWARE ANTI-TAKEOVER LAW

         As a Delaware corporation, the provisions of Section 203 of the
Delaware General Corporation Law apply to us. In general, Section 203 prohibits
a publicly-held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years following the date
that the person became an interested stockholder, unless:

         o    before the person became an interested stockholder, the board of
              directors approved either the business combination or the
              transaction that resulted in the person becoming an interested
              stockholder;

         o    after the transaction that resulted in the person becoming an
              interested stockholder, the interested stockholder owned at least
              85% of the voting stock of the corporation outstanding at the time
              the transaction commenced, excluding for purposes of determining
              the number of shares outstanding those shares owned by persons who
              are directors and also officers and by employee stock plans in
              which employee participants do not have the right to determine
              confidentially whether shares held under the plan will be tendered
              in a tender or exchange offer; or

         o    following the transaction in which the person became an interested
              stockholder, the business combination is approved by the board of
              directors and authorized at a meeting of the stockholders, by the
              affirmative vote of the holders of at least 66 2/3% of the
              outstanding voting stock that is not owned by the interested
              stockholder.

         Section 203 defines a "business combination" to include:

         o    any merger or consolidation involving the corporation and the
              interested stockholder;

         o    any sale, transfer, pledge or other disposition of 10% or more of
              the assets of the corporation involving the interested
              stockholder;

         o    any transaction that results in the issuance or transfer by the
              corporation of any stock of the corporation to the interested
              stockholder, with some exceptions;

         o    any transaction involving the corporation that has the effect of
              increasing the proportionate share of the stock of any class or
              series of the corporation beneficially owned by the interested
              stockholder; or

         o    the receipt by the interested stockholder of the benefit of any
              loans, advances, guarantees, pledges or other financial benefits
              provided by or through the corporation.

         In general, Section 203 defines an "interested stockholder" as any
entity or person beneficially owning 15% or more of the outstanding voting stock
of a corporation and any entity or person affiliated with or controlling or
controlled by that entity or person.

         A Delaware corporation may "opt out" of Section 203 by including a
provision in its original certificate of incorporation, or by adopting an
amendment to its certificate of incorporation or by-laws resulting approved by
holders of at least a majority of its outstanding voting stock, expressly
electing not to be governed by Section 203. Neither our



                                       33
<PAGE>   36


second restated certificate nor our by-laws contain any exclusion. Section 203
makes it more difficult for an "interested stockholder" to effect various
business combinations with a corporation for a three-year period.

RIGHTS AGREEMENT

         We have entered into a stockholder rights agreement. As with most
rights agreements, the terms of our rights agreement are complex and not easily
summarized, particularly as they relate to the acquisition of our common stock
and to exercisability of the rights. This summary may not contain all of the
information that is important to you. The following summary should be read in
conjunction with, and is qualified in its entirety by reference to, our rights
agreement, a copy of which is an exhibit to the registration statement of which
this prospectus is a part of.

         Under our rights agreement, each outstanding share of common stock has
one right to purchase four one-hundredths of a share of Series C preferred stock
attached to it. The purchase price per one one-hundredth of a share of Series C
preferred stock under the stockholder rights agreement is $25.00.

         The rights under our rights agreement are attached to the outstanding
certificates representing our common stock, and no separate certificates
representing the rights have been distributed. The rights will separate from our
common stock and be represented by separate certificates on the distribution
date, which will occur on the tenth day after public announcement that any
person or group has become an acquiring person, which means the beneficial owner
of at least 15% of our outstanding common stock, or ten business days, or a
later date as determined by the board of directors, after the date a person or
group commences a tender offer for 15% or more of our outstanding common stock.
After the rights separate from our common stock, certificates representing the
rights will be mailed to record holders of our common stock. Once distributed,
the rights certificates alone will represent the rights.

         All shares of our common stock issued before the date the rights
separate from the common stock will be issued with the rights attached. The
rights are not exercisable until the date the rights separate from the common
stock. The rights will expire on the December 1, 2001, unless the term of the
rights agreement is extended by us or the rights are earlier redeemed or
exchanged by us.

         After a distribution date occurs, each right will entitle the holder to
purchase four one-hundredths of a share of Series C preferred stock at a
purchase price of $25.00 per one one-hundredth of a share. In addition, after
the distribution date, each right will entitle the holder to purchase a number
of shares of our common stock having a then current market value of $200.00
subject to adjustment. Further, after the distribution date, each right will
entitle the holder to purchase a number of shares of common stock of the
acquiring person having a then current market value of $200.00, if any of the
following occurs:

         o    we merge with or consolidate into another entity;

         o    an acquiring person which is an entity merges with or consolidates
              into us; or

         o    we sell more than 50% of our assets or earning power.

         Under our rights agreement, any rights that are or were owned by an
acquiring person will be null and void. Our rights agreement contains exceptions
to the definition of "acquiring persons". American Meter and its affiliates and
associates will not be deemed to be an "acquiring person" so long as they own no
more than 25% of our outstanding common stock. In addition, no person or group
who becomes a beneficial owner of 15% or more of the outstanding shares of our
common stock, solely by virtue of acquiring the units, or exercising or
converting any securities included in the units, will be deemed to be an
acquiring person. Holders of the rights will have no rights as our stockholders,
including the right to vote or receive dividends, simply by virtue of holding
the rights.

         Our rights agreement contains exchange provisions which provide that
after an acquiring person becomes a beneficial ownership owner of 15% or more,
but less than 50%, of our outstanding common stock, our board of directors may,
at its option, exchange all or part of the then outstanding and exercisable
rights for common stock at an exchange ratio of four shares of common stock per
right.

         Our board of directors may, at its option, redeem all of the
outstanding rights under our rights agreement before any person or group
becoming an acquiring person. The redemption price under our rights agreement is
$0.04 per right. The right to exercise the rights will terminate upon the action
of our board of directors ordering the redemption of the rights and the only
right of the holders of the rights will be to receive the redemption price.

         Our rights agreement may be amended by our board of directors before
the date any person or group becomes an acquiring person, except that the
threshold of "acquiring person" status cannot be reduced below the greater of
10% or .001% above the highest percentage of common stock then beneficially
owned by any person or group, without reference to American Meter. However,
after the date any person or entity becomes an acquiring person, the rights
agreement may not be amended in any manner that would adversely affect the
interests of the holders of the rights. The prices and amounts above will be
approximately adjusted for stock splits and other changes to our capital stock.



                                       34
<PAGE>   37


         Our rights agreement contains provisions that have anti-takeover
effects. The rights may cause substantial dilution to a person or group that
attempts to acquire us without conditioning the offer on the redemption or the
termination of the rights. Accordingly, the existence of the rights may deter
acquirers from making takeover proposals or tender offers for our common stock.
However, the rights are not intended to prevent a takeover, but rather are
designed to enhance the ability of our board or directors to negotiate with an
acquirer on behalf of all the stockholders. In addition, the rights should not
interfere with a proxy contest or with any merger or business combination
approved by our board of directors.

TRANSFER AGENT AND REGISTRAR

         The transfer agent and registrar for the common stock and the warrants
is American Securities Transfer & Trust Co., Denver, Colorado.

LISTING

         The common stock is listed and traded on the Nasdaq National Market
under the trading symbol "MTEK". Until August ___, 2000, the warrants will be
listed and traded on the Nasdaq SmallCap Market under the trading symbol
"MTEKW."

LIMITATION OF LIABILITY AND INDEMNIFICATION

         Section 145 of the Delaware General Corporation Law provides for broad
indemnification of the directors, officers, employees and agents of a
corporation. As permitted by Section 145 of the DGCL, our second restated
certificate permits us to indemnify any person who was or is threatened to be
made a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, other than an action
by us or in our right, by reason of the fact the person is or was our officer of
director, or is or was serving at our request as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses, including attorneys' fees, judgments, fines and
amounts paid in settlement actually and reasonably incurred by the person in
connection with the action, suit or proceeding, provided that the person acted
in good faith and in a manner the person reasonably believed to be in or not
opposed to our best interests and, with respect to any criminal action or
proceeding, had no reasonable cause to believe the person's conduct was
unlawful. We are also permitted to indemnify the same persons against expenses,
including attorneys' fees, actually and reasonably incurred by these persons in
connection with the defense or settlement of any threatened, pending or
completed action or suit by us or in our right under the same conditions, except
that no indemnification will be made in respect to any claim, issue or matter as
to which the person has been adjudged to be liable to us unless, and only to the
extent that, the adjudicating court determines that the indemnification is
proper under the circumstances. To the extent these persons are successful on
the merits or otherwise in defense of any action, suit or proceeding,
indemnification is mandatory. We may also pay the expenses incurred in any
action, suit or proceeding in advance of its final disposition, upon receipt of
an appropriate undertaking by the person. These rights are not exclusive of any
other right which any person may have or hereafter acquire under any statute, or
under any provision of our second restated certificate, our by-laws, or under
any agreement, vote of stockholders or disinterested directors or otherwise. No
repeal or modification of these provisions of our second restated certificate
will in any way diminish or adversely affect the rights of any person to
indemnification thereunder in respect of any occurrences or matters arising
before any repeal or modification.

         Our by-laws provide that we shall indemnify our directors, officers,
employees and agents to the extent permitted by the DGCL. We have also entered
into indemnification agreements with each of our directors requiring us to
indemnify them against liabilities that they incur in their capacity as
directors.

         Our second restated certificate also specifically authorizes us to
maintain insurance and to grant similar indemnification rights to our employees
or agents. We maintain an insurance policy indemnifying our directors and
officers against liabilities, including liabilities arising under the Securities
Act, which might be incurred by them in these capacities.

         As permitted by Section 102(b)(7) of the DGCL, our second restated
certificate also eliminates the personal liability of our directors to us and
our stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability:

         o    for any breach of a director's duty of loyalty to us or our
              stockholders;

         o    for acts or omissions not in good faith or which involve
              intentional misconduct or a knowing violation of law;



                                       35
<PAGE>   38
         o    under Section 174 of the DGCL, relating to unlawful payments of
              dividends or unlawful stock purchases or redemptions; and

         o    for any transaction in which a director derived an improper
              personal benefit.

         These provisions do not limit or eliminate our rights or the rights of
any stockholder to seek non-monetary relief, such as an injunction or
rescission, in the event of a breach of a director's fiduciary duty. These
provisions will also not alter a director's liability under federal securities
laws.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to our directors, officers and controlling persons under
the foregoing provisions or otherwise, we have been advised that in the opinion
of the SEC this indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable.

                                  LEGAL MATTERS

         The validity of the securities offered under this prospectus will be
passed upon for us by Kegler, Brown, Hill & Ritter Co., L.P.A., Columbus, Ohio.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 145 of the General Corporation Law of the State of Delaware
("DGCL") provides for indemnification of the directors, officers, employees and
agents of a corporation under certain conditions and subject to certain
limitations. As permitted by Section 145 of the DGCL, Metretek's Second Restated
Certificate of Incorporation ("Second Restated Certificate") permits Metretek to
indemnify any person who was or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, other than an action by or in the
right of Metretek, by reason of the fact such person is or was an officer of
director of Metretek, or is or was serving at Metretek's request as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, against expenses, including attorneys' fees,
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding, provided that
such person acted in good faith and in a manner such person reasonably believed
to be in or not opposed to the best interests of Metretek, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe such
person's conduct was unlawful. Metretek is also permitted to indemnify the same
persons against expenses, including attorneys' fees, actually and reasonably
incurred by such persons in connection with the defense or settlement of any
threatened, pending or completed action or suit by or in the right of Metretek
under the same conditions, except that no indemnification will be made in
respect to any claim, issue or matter as to which such person has been adjudged
to be liable to Metretek unless, and only to the extent that, the adjudicating
court determines that such indemnification is proper under the circumstances. To
the extent such persons are successful on the merits or otherwise in defense of
any such action, suit or proceeding, such indemnification is mandatory. Metretek
may also pay the expenses incurred in any such action, suit or proceeding in
advance of its final disposition, upon receipt of an appropriate undertaking by
such person. Such rights are not exclusive of any other right which any person
may have or hereafter acquire under any statute, or under any provision of the
Second Restated Certificate, Metretek's By-Laws, or under any agreement, vote of
stockholders or disinterested directors or otherwise. No repeal or modification
of these provisions of the Restated Certificate will in any way diminish or
adversely affect the rights of any person to indemnification thereunder in
respect of any occurrences or matters arising before any such repeal or
modification.

         Metretek's Amended and Restated By-Laws provide that Metretek shall
indemnify its directors, officers, employees and agents to the extent permitted
by the DGCL.

         As permitted by Section 102(b)(7) of the DGCL, Metretek's Second
Restated Certificate also eliminates the personal liability of Metretek's
directors to Metretek or its stockholders for monetary damages for breach of
fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to us or out stockholders; (ii) for acts or omissions
not in good faith or which involve intentional misconduct or a knowing
<PAGE>   42


violation of law; (iii) under Section 174 of the DGCL, relating to unlawful
payments of dividends or unlawful stock purchases or redemptions; and (iv) for
any transaction from which a director derived an improper personal benefit.

         Metretek's Second Restated Certificate also specifically authorizes
Metretek to maintain insurance and to grant similar indemnification rights to
employees or agents of Metretek. The directors and officers of Metretek are
covered by an insurance policy indemnifying them against certain liabilities,
including certain liabilities arising under the Securities Act, which might be
incurred by them in such capacity.

         Metretek has also entered into indemnification agreements with each of
its directors that require Metretek to indemnify its directors against certain
liabilities, including certain liabilities arising under the Securities Act,
which might be incurred by them in such capacity.

                  (1) File, during any period in which it offers or sells

                                    represent a fundamental change in the

                                    pursuant to Rule 424(b) if, in the
                                    aggregate, the changes in volume and price
                                    represent no more than a 20% change in the
                                    maximum aggregate offering price set forth
                                    in the "Calculation of Registration Fee"
                                    table in the effective registration
                                    statement; and
<PAGE>   44


                           (iii)    Include any additional or changed material
                                    information on the plan of distribution;

                           provided, however, that paragraphs (i) and (ii) above
                           do not apply if the information required in a
                           post-effective amendment is incorporated by reference
                           from periodic reports filed by Metretek under the
                           Exchange Act.

                  (2) For determining liability under the Securities Act, treat
                  each post-effective amendment as a new registration statement
                  of the securities offered, and the offering of the securities
                  at that time to be the initial bona fide offering.

                  (3) File a post-effective amendment to remove from
                  registration any of the securities being registered that
                  remain unsold at the end of the offering.


         (b) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Small Business Issuer pursuant to the foregoing provisions, or
otherwise, the Small Business Issuer has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Small Business Issuer of expenses incurred or paid by a director, officer or
controlling person of the Small Business Issuer in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Small Business
Issuer will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

         (c)      Metretek, the Small Business Issuer, will:

                  (1) For determining any liability under the Securities Act,
                  treat the information omitted from the form of prospectus
                  filed as part of this Registration Statement in reliance upon
                  Rule 430A and contained in a form of prospectus filed by the
                  Small Business Issuer under Rule 424(b)(1) or (4) or 497(h)
                  under the Securities Act as part of this Registration
                  Statement as of the time the Commission declared if effective.


                  (2) For determining any liability under the Securities Act,
                  treat each post-effective amendment that contains a form of
                  prospectus as a new registration statement for the securities
                  offered in the registration statement, and that offering of
                  the securities at that time as the initial bona fide offering
                  of those securities.

         (d) Metretek hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of Metretek's annual report
pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
