                           METRETEK TECHNOLOGIES, INC.

BACKGROUND

      Through our subsidiaries, we are a diversified provider of energy
technology measurement products, services and data management systems to
industrial and commercial users and suppliers of natural gas and electricity. We
currently conduct our operations through three subsidiaries:

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

      -     PowerSecure, Inc., based in Wake Forest, North Carolina, which
            designs, engineers, sells and manages distributed generation systems
            marketed primarily to industrial and commercial users of
            electricity.

      -     Metretek, Incorporated, which we refer to as Metretek Florida, based
            in Melbourne, Florida, which provides data collection, telemetry and
            other types of machine-to-machine connectivity solutions for
            applications such as automatic meter reading cathodic protection and
            other types of remote monitoring and collection applications.
            Metretek Contract Manufacturing Company, Inc., a Melbourne, Florida
            based subsidiary of Metretek Florida, provides outsourced
            manufacturing services with a primary focus on printed circuit
            boards, mechanical and electrical assemblies.

      In this prospectus, references to "Metretek", "we", "us" and "our" refer
to Metretek Technologies, Inc. together with its subsidiaries, unless we state
otherwise or the context indicates otherwise.

      We were incorporated in Delaware on April 5, 1991 under the name "Marcum
Natural Gas Services, Inc.," and we changed our name in June 1999 to "Metretek
Technologies, Inc." Our principal executive offices are located at 303 East
Seventeenth Street, Suite 660, Denver, Colorado 80203, and our telephone number
at those offices is (303) 785-8080.

BUSINESS STRATEGY

      Our business strategy is to position ourselves as an integrated provider
of data management products, services and systems that enhance the availability
of management information and services primarily to suppliers and users of
energy. While our products, services and systems have historically been aimed
primarily at the natural gas industry, we are focusing more of our current and
future products, services and systems to other segments of the energy industry,
especially the electricity industry, as well as to other industries that require
data management services. The energy industry continues to experience
fundamental regulatory and structural changes and significant new trends. Our
strategy is to acquire, develop, operate and expand businesses that are
positioned to take advantage of these changes and trends.

      In implementing our business strategy, we have acquired or formed the
following important businesses:

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


                                       3

      -     In 1994, we acquired Metretek Florida.

      -     In 1997, we acquired two printed circuit based contract
            manufacturing firms to support and expand Metretek Florida's
            operations.

      -     In 1998, we acquired the electronic corrector business from American
            Meter Company to further expand the product and service offerings of
            Metretek Florida.

      -     In 2000, we formed PowerSecure to develop and operate our
            distributed generation business.

      -     In 2001, we acquired Industrial Automation, Inc., a process control
            and switchgear design and manufacturing firm, as part of
            PowerSecure's growth strategy.

      -     In 2002, we formed MCM as a subsidiary of Metretek Florida to
            operate and expand our contract manufacturing business.

      -     In 2003, we developed InvisiConnect(TM), a machine to machine
            connection solution for wireless network technology, to enhance the
            product, service and technology offerings of Metretek Florida.

      While we regularly engage in discussions relating to potential
acquisitions and dispositions of assets, businesses and companies, as of the
date of this prospectus we have not entered into any binding agreement or
commitment with respect to any material acquisition or disposition.

RECENT DEVELOPMENTS

      In May 2004, we completed a private placement to institutional and
accredited investors of 3,510,548 shares of our common stock and warrants to
purchase 702,109 shares of our common stock raising gross proceeds of $10.9
million. The price paid in the private placement was $3.10 per unit, each unit
consisting of one share of common stock and a warrant to purchase 0.2 shares of
common stock. Roth Capital Partners, LLC acted as the placement agent in the
private placement.

      We received net cash proceeds of approximately $9.9 million from the
private placement, after deducting transaction expenses including the placement
agent's fee. The net proceeds from the private placement are intended to be used
principally to meet our mandatory redemption obligations related to our Series B
preferred stock, which matures on December 9, 2004, and for other business
commitments and initiatives.

      The warrants issued in the private placement have an exercise price of
$3.41 per share of common stock and expire in May 2009. The warrants are
callable by us commencing one year after issuance if the trading price of our
common stock is at least two times the warrant exercise price for 30 consecutive
trading days and certain other conditions are satisfied. The warrants may be
exercised by the holders on a cashless basis, under certain circumstances. In
addition to the warrants issued to the investors, we issued warrants to purchase
up to 351,054 shares of common stock to the placement agent with the same basic
terms as the warrants issued to the investors. This prospectus is a part of the
registration statement we agreed to file with the Securities and Exchange
Commission to register the offer from time to time of shares of our common stock
issued in the private placement or upon the exercise of the warrants.

      Also in May 2004, certain holders of our outstanding shares of Series B
preferred stock converted a total of 2,500 shares of our Series B preferred
stock, including accrued and unpaid dividends, and received upon such conversion
1,209,133 shares of common stock plus warrants to purchase 1,209,133 shares of
common stock exercisable until June 9, 2005 at an exercise price of $3.0571 per
share, which is the same price as the conversion price of the Series B preferred
stock into each share of common stock. We agreed to include the 55,871 shares of
common stock issued to the holders of Series B preferred stock that had not
previously registered, plus all of the shares of common stock issuable upon
exercise of the warrants issued to those holders, in the registration statement
to be filed in connection with the private placement.

                                  RISK FACTORS

      An investment in our common stock involves a number of significant risks.
You should carefully consider the risks, uncertainties and other factors
described below, along with the other information contained or incorporated by
reference in this prospectus, before making an investment decision. In addition,
the risks, uncertainties and other factors described below are not the only ones
we face. There may be additional risks, uncertainties and other factors that we
do not currently consider material or that are not currently known to us. If any
of the following risks were to occur, our business, affairs, 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 common stock
could 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 in each year since our inception in 1991,
including a net loss applicable to common shareholders of $11,000 in fiscal 2003
and a net loss applicable to common shareholders of $4.2 million in fiscal 2002.
We had a net loss applicable to common shareholders of approximately $227,000 in
the quarter ended March 31, 2004. As of March 31, 2004, we had an accumulated
deficit of approximately $54.2 million. We may never achieve profitability, and
even if we do we may not be able to sustain or increase that profitability on a
quarterly or annual basis in the future. We may incur expenses in excess of
revenues, including significant costs in developing and expanding the contract
manufacturing business of MCM and the InvisiConnect(TM) business of Metretek
Florida, and we will continue to accrue the preferred stock deemed distribution
in fiscal 2004. In addition, while our revenues in fiscal 2003 increased
significantly over our revenues in fiscal 2002, there is no guarantee that our
future revenues will continue to grow significantly, if at all, or that they
will ever exceed our costs and expenses. If our future revenues do not meet our
expectations, or if our operating expenses exceed what we anticipate or cannot
be reduced below our revenues, our business, financial condition and results of
operations will be materially and adversely affected.

      IF WE ARE UNABLE TO SATISFACTORILY RESTRUCTURE, OR TO RAISE SUFFICIENT
      ADDITIONAL CAPITAL FUNDS TO MEET, OUR OBLIGATION TO REDEEM THE REMAINING
      OUTSTANDING SHARES OF OUR SERIES B PREFERRED STOCK IN DECEMBER 2004, THEN
      OUR ASSETS, BUSINESS, FINANCIAL CONDITION AND RESULTS OF OPERATIONS MAY BE
      MATERIALLY AND ADVERSELY AFFECTED, AND WE MAY FACE A CHANGE IN CONTROL IN
      OUR BOARD OF DIRECTORS.

      Under the terms of our Series B preferred stock, we are required to redeem
all shares of Series B preferred stock that remain outstanding on December 9,
2004 at a redemption price equal to the liquidation preference of $1,000 per
share plus accumulated and unpaid dividends. As of June 1, 2004, this redemption
obligation was approximately $6.3 million. In May 2004 we addressed this
obligation by completing a private placement that raised net proceeds of $9.9
million and by the conversion of 2,500 of the outstanding 7,000 outstanding
shares of Series B preferred stock. These transactions are intended to allow us
to meet the Series B preferred stock redemption obligation. The Series B
preferred stock is convertible, at the option of the holders thereof, into
common stock at the conversion rate of $3.0571 per share of common stock. While
the conversion of any further of Series B preferred stock into shares of common
stock prior to the redemption date will reduce our redemption obligation, we
cannot provide any assurance that any further shares of Series B preferred stock
will be converted. In addition, we may, but do not intend, to restructure that
obligation with the holders of our Series B preferred stock in a manner
satisfactory to us, such as by deferring the redemption date on all or part of
the shares. However, there is no assurance we will be able to do either, as such
actions require the consents of others that we may not obtain. In addition, our
ability to raise additional capital depends on many factors, including general
market conditions, our operating performance, and investor sentiment, and thus
cannot be assured. Moreover, the terms of any financing could be adverse to the
interests of our stockholders. If we are unable to satisfy or satisfactorily
restructure our redemption obligations under the Series B preferred stock, then
our business, financial condition and results of operations may be materially
and adversely affected. In such event, holders of the Series B preferred stock
will have the right to elect sufficient directors to control a majority of our
board of directors until the redemption obligation is fully satisfied, and the
dividend rate on the Series B preferred stock will increase from 8% to 10% and
continue to increase by 0.5% each six months to a maximum rate of 15%.


                                       6

      WE MAY ALSO REQUIRE A SUBSTANTIAL AMOUNT OF ADDITIONAL FUNDS TO FUND OUR
      OTHER CAPITAL REQUIREMENTS AND TO FINANCE THE GROWTH OF OUR BUSINESS, BUT
      WE MAY NOT BE ABLE TO RAISE A SUFFICIENT AMOUNT OF FUNDS TO DO SO ON TERMS
      FAVORABLE TO US AND OUR STOCKHOLDERS OR AT ALL.

      In addition to our obligation to redeem the Series B preferred stock in
December 2004, we may need to obtain additional capital to fund our other
capital obligations and to finance the development and expansion of our
business. For example, we will need substantial additional capital to expand our
contract manufacturing business and to finance the development of our
InvisiConnect(TM) business. In addition, we may need substantial additional
capital if we proceed to develop the company-owned business of PowerSecure, in
order to fund our acquisition of capital equipment for distributed generation
systems to be owned by PowerSecure. Further, under the proposed settlement of
the class action lawsuit currently pending against us, we are required to make
payments on a $3 million promissory note, plus interest, over a four year period
commencing on June 30, 2004. If the proposed settlement to the class action
litigation is not approved and the class action proceeds against us, a
resolution of the litigation adverse to us could also significantly increase our
cash requirements beyond our available capital resources. In addition, from time
to time as part of our business plan, we engage in discussions regarding
potential acquisitions of businesses and technologies. While our ability to
finance future acquisitions will probably require us to raise additional
capital, as of the date of this prospectus, we have not entered into any
agreement committing us to any such acquisition. Moreover, unanticipated events,
over which we have no control, could increase our operating costs or decrease
our ability to generate revenues from product and service sales, necessitating
additional capital. We continually evaluate our cash flow requirements as well
as our opportunity to raise additional capital in order to improve our financial
position. We cannot provide any assurance that we will be able to raise
additional capital when needed or desired, or that the terms of such capital
will be favorable to us and our stockholders.

      We completed a private placement in May 2004, in which we raised net
proceeds of approximately $9.9 million. With these proceeds, we currently
believe that our capital resources are sufficient to meet our financial
obligations for at least the next 12 months. In addition to our cash on hand, we
have a $3 million credit facility through September 2006. Our ability to borrow
funds under the credit facility is limited to our loan availability based upon
certain assets of our subsidiaries. As of March 31, 2004, we had an aggregate
loan availability under the credit facility of approximately $2,117,000, of
which $1,709,000 had been borrowed, leaving $408,000 available for future use.
The amount of our credit availability, as well as the amount borrowed under the
credit facility, will change in the future depending on our asset base and our
capital requirements.

      Our current credit facility has a number of financial covenants that our
subsidiaries must satisfy. Our ability to satisfy those covenants depends
principally upon our ability to achieve positive operating performance. If any
of our borrowing subsidiaries is unable to fully satisfy the financial covenants
of the credit facility, it will breach the terms of the credit facility. We have
secured our obligations under the credit facility by pledging substantially all
of our assets as collateral. Additionally, our subsidiaries have guaranteed the
repayment of our obligations under the credit facility. Any breach of these
covenants, or any other event or circumstance that our lender deems impairs our
ability to fulfill our obligations under the credit facility, could result in a
default under the credit facility and an acceleration of payment of all
outstanding debt owed, which would materially and adversely affect our business.

      We may seek to raise any needed or desired additional capital from the
proceeds of public or private equity or debt offerings at the Metretek
Technologies level or at the subsidiary level or both, through asset or business
sales, from traditional credit financings or from other financing sources. Our
ability to obtain additional capital when needed or desired will depend on many
factors, including general market conditions, our operating performance and
investor sentiment, and thus cannot be assured. In addition, depending on how it
is structured, raising capital could require the consent of other persons,
including our lender, the holders of our Series B preferred stock or the
investors in the May 2004 private placement. Even if we are able to raise
additional capital, the terms of any financing could be adverse to the interests
of our stockholders. For example, the terms of debt financing could include
covenants that restrict our ability to operate our business or to expand our
operations, while the terms of an equity financing, involving the issuance of
capital stock or of securities convertible into capital stock, could dilute the
percentage ownership interests of our stockholders, and the new capital stock or
other new securities could have rights, preferences or privileges senior to
those of our current stockholders. We cannot assure you that sufficient
additional funds will be available to us when needed or desired or that, if
available, such funds can be obtained on terms favorable to us and our
stockholders and acceptable to those persons that must consent to the financing.
Our inability to obtain sufficient additional capital on a timely basis on
favorable terms could have a material adverse


                                       7

effect on our business, financial condition and results of operations.

      IF THE PROPOSED SETTLEMENT OF THE CLASS ACTION DOES NOT BECOME EFFECTIVE,
      OR IF IN THE FUTURE WE BECOME SUBJECT TO NEW LAWSUITS, AND IF ANY OF THOSE
      LAWSUITS ARE SUCCESSFULLY PROSECUTED AGAINST US, OUR BUSINESS, FINANCIAL
      CONDITIONS AND RESULTS OF OPERATING COULD BE MATERIALLY AND ADVERSELY
      AFFECTED.

      We are in the process of resolving a class action lawsuit against us and
some of our subsidiaries and affiliates and their officers, directors and
trustees through a proposed settlement. The class action and the terms and
conditions of the proposed settlement are described in our Annual Report on 10-K
for the fiscal year ended December 31, 2003 and Quarterly Report on Form 10-Q
for the quarter ended March 31, 2004 that accompanies this prospectus. The
settlement is subject to various conditions, including preliminary and final
court approval, and is subject to appeal or challenge even if final approval is
granted by the court. Accordingly, we cannot provide any assurance that the
settlement will become effective. If the settlement does not become effective,
then the class action will continue to be prosecuted against us. While we expect
to defend the claims against us in the class action vigorously, due to the
inherent uncertainty of litigation, it is not possible at this time to predict
the outcome of this litigation or the impact the ultimate resolution of this
litigation would have on us, if the settlement does not become effective. An
adverse judgment against us would materially and adversely affect our business,
financial condition and results of operations.

      From time to time we are also involved in other disputes and legal actions
that arise in the ordinary course of business. We cannot provide any assurance
that any such future litigation and claims against us could not materially and
adversely affect our business, financial condition and results of operation.

      OUR FUTURE OPERATING RESULTS ARE DIFFICULT TO PROJECT AND HAVE FLUCTUATED
      SIGNIFICANTLY IN THE PAST, AND FLUCTUATIONS IN THE FUTURE MAY ADVERSELY
      AFFECT THE TRADING PRICE OF OUR COMMON STOCK.

      Our quarterly revenues, expenses, margins, net income and other operating
results have fluctuated significantly from quarter-to-quarter, period-to-period
and year-to-year 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. These factors include, without limitation, the
following:

      -     the size, timing and terms of sales and orders, including customers
            delaying, deferring or canceling purchase orders, or making smaller
            purchases than expected;

      -     our ability to implement our business plans and strategies and the
            timing of such implementation;

      -     the timing, pricing and market acceptance of our new products and
            services such as Metretek Florida's new InvisiConnect offering;

      -     the pace of development of our new businesses and the growth of
            their markets;

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

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

      -     changes in the mix of products and services having differing
            margins;

      -     changes in the mix of international and domestic revenues;

      -     the life cycles of our products and services;

      -     budgeting cycles of utilities and other major customers;

      -     general economic and political conditions;

      -     the resolution of pending and any future litigation and claims;

      -     economic conditions in the energy industry, especially in the
            natural gas and electricity sectors;

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

      -     changes in the prices charged by our suppliers;

      -     our ability to make and obtain the expected benefits from
            acquisitions of technology or businesses, and the costs related to
            such acquisitions;


                                       8

      -     changes in our operating expenses; and

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

      Because we have little or no control over most of these factors, our
operating results are difficult to predict. Any substantial adverse change in
any of these factors could negatively affect our business and results of
operations.

      Due to all of these factors and the other risks discussed in this
prospectus, you should not rely on quarter-to-quarter, period-to-period or
year-to-year comparisons of our results of operations as an indication of our
future performance. Quarterly, period and annual comparisons of our operating
results are not necessarily meaningful or indicative of 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, causing the trading
price of our common stock to fall.

      BECAUSE SOME OF OUR BUSINESSES AND SOME OF OUR PRODUCT AND SERVICE
      OFFERINGS HAVE LIMITED HISTORIES AND ARE BASED UPON UNPROVEN BUSINESS
      STRATEGIES THAT ARE STILL BEING DEVELOPED, LIMITED INFORMATION IS
      AVAILABLE TO EVALUATE THEIR FUTURE PROSPECTS.

      Our business strategy includes the development and expansion of new
businesses and of new product and service offering from time to time. Our plans
and strategies with respect to these new businesses are often based on unproven
models and must be developed and modified. Our future success depends in large
part upon our ability to develop these new businesses so that they will generate
significant revenues, profits and cash flow.

      As a company developing new businesses in the rapidly evolving energy and
technology markets, we face numerous risks and uncertainties which are described
in this Item as well as other parts of this prospectus. Some of these risks
relate to our ability to:

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

      -     attract customers to our new businesses;

      -     anticipate and adapt to the changing energy markets and end-user
            preferences;

      -     attract, retain and motivate qualified personnel;

      -     respond to actions taken by our competitors;

      -     integrate acquired businesses, technologies, products and services;

      -     generate revenues, gross margins, cash flow and profits from sales
            of new products and services;

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

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

      Our business and financial results in the future will depend heavily on
the market acceptance and profitability of our new businesses and these new
product and service offerings lines. If we are unsuccessful in addressing these
risks or in executing our business strategies, or if our business model fails or
is invalid, then our business would be materially and adversely affected.

      RESTRICTIONS IMPOSED ON US BY THE TERMS OF OUR SERIES B PREFERRED STOCK,
      OUR CURRENT CREDIT FACILITY, THE PROPOSED CLASS ACTION SETTLEMENT AND THE
      TERMS OF OUR RECENT PRIVATE PLACEMENT COULD LIMIT HOW WE CONDUCT OUR
      BUSINESS AND OUR ABILITY TO RAISE ADDITIONAL CAPITAL.

      The terms of our Series B preferred stock, our current credit facility,
our proposed class action settlement and of our recent private placement contain
financial and operating covenants that limit the discretion of our management.
These covenants place significant restrictions on our ability to:

      -     incur additional indebtedness;

      -     create liens or other encumbrances;


                                       9

      -     issue or redeem our securities;

      -     make dividend payments and investments;

      -     amend our charter documents;

      -     sell or otherwise dispose of our or our subsidiaries' stock or
            assets;

      -     liquidate or dissolve;

      -     merge or consolidate with other companies; or

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

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

      -     limited in how we conduct our business;

      -     unable to raise additional capital, through debt or equity
            financings, when needed for our operations and growth; and

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

      If, as a result of these covenants, we are unable to pursue a favorable
transaction or course of action or to respond to an unfavorable event, condition
or circumstance, then our business could be materially and adversely affected.

      DIVIDENDS ON OUR SERIES B PREFERRED STOCK DECREASE OUR NET INCOME OR
      INCREASE OUR NET LOSS AVAILABLE TO COMMON SHAREHOLDERS AND DECREASE OUR
      NET INCOME OR INCREASE OUR NET LOSS PER COMMON SHARE.

      Due to our issuance of our Series B preferred stock in December 1999 and
February 2000 as part of a private placement of units of securities that also
included shares of common stock and common stock purchase warrants, we recognize
the 8% coupon rate on the Series B preferred stock and certain "deemed
distributions" as dividends on the Series B preferred stock. The proceeds from
the private placement of the units were allocated to our common stock, the
common shares purchase warrants and the Series B preferred stock based on the
relative fair value of each. This allocation process resulted in the Series B
preferred stock that we sold in February 2000 being initially recorded at a
discount from its $1,000 per share liquidation value. This discount is being
recorded as a distribution over the term of the Series B preferred stock.
Another discount resulted from the increase in the fair market value of a share
of our common stock from the date we offered to sell the securities to February
2000, the date we actually issued the securities. This increase caused the
conversion feature of the Series B preferred stock to be "in the money" in
February 2000. The discount related to the "in the money" conversion feature has
been recorded as a distribution between February 2000 and June 2000, after which
date the Series B preferred stock could first be converted into our common
stock. The Series B preferred stock dividends adversely affected our operating
results in fiscal 2001, fiscal 2002, fiscal 2003 and the first quarter of fiscal
2004 by significantly decreasing the net income or increasing the net loss
available to common shareholders and decreasing the net income or increasing the
net loss per common share, and will continue to adversely affect our operating
results through fiscal 2004. By adversely affecting our operating results, the
accounting treatment of these dividends could adversely affect the trading price
of our common stock.

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

      We currently derive a significant portion of our revenue from sales by
Metretek Florida of its products and services to the utility industry, and
particularly the natural gas utility industry. A key reason that we have
experienced variability of operating results on both an annual and quarterly
basis has been utility purchasing patterns, including delays of purchasing
decisions, as the result of mergers and acquisitions in the utility industry and
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


                                       10

committees to evaluate the purchase proposals, review different technical
options with vendors, analyze performance and cost/benefit justifications and
perform a regulatory review, in addition to applying a normal budget approval
process within the utility. In addition, utilities may defer purchases of our
products and services if the utilities reduce capital expenditures as the result
of mergers and acquisitions, pending or unfavorable regulatory decisions, poor
revenues due to weather conditions, rising interest rates or general economic
downturns, among other factors. The natural gas utility industry has been
virtually the sole market for Metretek Florida's products and services. 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 Metretek Florida's products
and services. The continuation of this uncertain regulatory climate will
materially and adversely affect our revenues from sales to utilities.

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

      MANY OF OUR PRODUCTS AND SERVICES EXPERIENCE LONG AND VARIABLE SALES
      CYCLES, WHICH COULD HAVE A NEGATIVE IMPACT ON OUR RESULTS OF OPERATIONS
      FOR ANY GIVEN QUARTER OR YEAR.

      Our products and services are often used by our customers to address
critical business needs. Customers generally consider a wide range of issues
before making a decision to purchase our products and services. In addition, the
purchase of some of our products and services involves a significant commitment
of capital and other resources by a customer. This commitment often requires
significant technical review, assessment of competitive products and approval at
a number of management levels within a customer's organization. Our sales cycle
may vary based on the industry in which the potential customer operates and is
difficult to predict for any particular transaction. The length and variability
of our sales cycle makes it difficult to predict whether particular sales will
be concluded in any given quarter. While our customers are evaluating our
products and services before they place an order with us, we may incur
substantial sales and marketing and research and development expenses to
customize our products to the customer's needs. We may also expend significant
management efforts, increase manufacturing capacity and order long-lead-time
components or materials prior to receiving an order. Even after this evaluation
process, a potential customer may not purchase our products. As a result, these
long sales cycles may cause us to incur significant expenses without ever
receiving revenue to offset those expenses.

      IF WE ARE UNABLE TO DEVELOP AND OFFER NEW AND ENHANCED PRODUCTS AND
      SERVICES THAT ACHIEVE MARKET ACCEPTANCE IN A TIMELY MANNER, OUR OPERATING
      RESULTS AND COMPETITIVE POSITION COULD SUFFER.

      Our success depends on our ability to develop and offer new and enhanced
products and services that achieve market acceptance in a timely and
cost-effective manner. The development of technology is often complex, and we
occasionally have experienced delays in completing the development and
introduction of new products and services and enhancements thereof. Successful
development and market acceptance of our products and services depends on a
number of factors, including:

      -     changing requirements of customers;

      -     accurate prediction of market requirements;

      -     timely completion and introduction of new designs;


                                       11

      -     quality, price, performance, power use and size of our products;

      -     availability, quality, price and performance of competing products,
            services and technologies;

      -     our customer service and support capabilities and responsiveness;

      -     successful development of our relationships with existing and
            potential customers; and

      -     changes in technology, industry standards or end-user preferences.

      We cannot provide assurance that products and services which we recently
have developed or may develop in the future will achieve market acceptance. If
we fail to develop new or enhanced products and services that achieve market
acceptance, our growth prospects, operating results and competitive position
could be materially and adversely affected.

      FROM TIME TO TIME WE DEPEND ON REVENUES FROM SIGNIFICANT CONTRACTS, AND
      ANY LOSS, CANCELLATION, REDUCTION, OR DELAY IN THESE CONTRACTS COULD HARM
      OUR BUSINESS AND OPERATING RESULTS.

      From time to time, one or more of our subsidiaries have derived a material
portion of our revenue from one or more individual contracts that could be
terminated by the customer at the customer's discretion. It is possible that in
future periods we may again enter into individual contracts with significant
revenue concentrations. If such contracts were to be terminated, our revenues
and net income would significantly decline. Our success will depend on our
continued ability to develop and manage relationships with significant
customers. We cannot be sure that we will be able to retain our largest
customers, that we will be able to attract additional customers, or that our
customers will continue to purchase our products and services in the same
amounts as in prior years. Our business and operating results would be hindered
by:

      -     the loss of one or more large customers;

      -     any reduction or delay in sales to these customers;

      -     our inability to successfully develop relationships with additional
            customers; or

      -     future price concessions that we may have to make.

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

      The markets in which our businesses operate are characterized by rapid
technological change, frequent introductions of new and enhanced products and
services, evolving industry standards and changes in customer needs. Significant
technological changes could render our existing and planned new products,
services and technology obsolete. Our future success will depend, in large part,
upon our ability to:

      -     effectively use and develop leading technologies;

      -     continue to develop our technical expertise;

      -     enhance our current products and services;

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

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

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

      Even if we do successfully respond to technological advances and emerging
industry standards, the integration of new technology may require substantial
time and expense, and we cannot assure you that we will succeed in adapting our
products, services and technology in a timely and cost-effective manner. We may
experience financial or technical difficulties or limitations that could prevent
us from introducing new or enhanced products or services. Furthermore, these new
or enhanced products, services and technology may contain problems


                                       12

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 technology and operating systems may impede market acceptance of our
products, services and technology. 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. In the past, we have experienced delays in releasing new products and
services and enhancements, and we may experience similar delays in the future.
These delays or problems in the installation of implementation of our new
products and services and enhancements may cause customers to forego purchases
of our products and services to purchase those of our competitors.

      IF WE ARE UNABLE TO CONTINUE TO ATTRACT AND RETAIN KEY PERSONNEL, OUR
      BUSINESS WILL BE MATERIALLY AND ADVERSELY AFFECTED.

      We believe our future success will depend in large part upon our ability
to attract and retain highly qualified technical, managerial, sales, marketing,
finance and operations personnel. Competition for qualified personnel is
intense, and we cannot assure you that we will be able to attract and retain
those key employees in the future. The loss of the services of any 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. Our failure to attract and retain
highly qualified personnel could materially and adversely affect our business.

      WE FACE INTENSE COMPETITION IN THE MARKETS FOR OUR PRODUCTS, SERVICES AND
      TECHNOLOGY, AND IF WE CANNOT SUCCESSFULLY COMPETE IN THOSE MARKETS, OUR
      BUSINESS WILL BE MATERIALLY AND ADVERSELY AFFECTED.

      The markets for our products, services and technology are intensely
competitive and subject to rapidly changing technology, new products and
services, frequent performance improvements and evolving industry standards. We
expect the intensity of competition to increase in the future because the growth
potential and deregulatory environment of the energy market have attracted and
are anticipated to continue to attract many new competitors, including new
business as well as established businesses from different industries.
Competition may also increase as a result of industry consolidation. As a result
of increased competition, we may have to reduce the price of our products and
services, and we may experience reduced gross margins and loss of market share,
any one of which could significantly reduce our future revenues and operating
results.

      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 compete successfully in the future. Our
inability to compete successfully in any respect or to timely respond to market
demands or changes would have a material adverse effect on our business,
conditions and results of operations.


                                       13

      DOWNTURNS IN GENERAL ECONOMIC AND MARKET CONDITIONS COULD MATERIALLY AND
      ADVERSELY AFFECT OUR BUSINESS.

      There is potential for a downturn in general economic and market
conditions. Various segments of the economy in general, and of the energy
industry in particular, have experienced significant economic downturns
characterized by decreased product demand, price erosion, work slowdown, and
layoffs. The most recent downturn was especially strong in the technology
industry. Moreover, there is increasing uncertainty in the energy and technology
markets attributed to many factors, including global economic conditions and
strong competitive forces. Our future results of operations may experience
substantial fluctuations from period to period as a consequence of these
factors, and such conditions and other factors affecting capital spending may
affect the timing of orders from major customers. An economic downturn coupled
with a decline in our revenues could affect our ability to secure additional
financing or raise additional funds to meet capital requirement, support working
capital requirements and growth objectives, maintain existing financing
arrangements, or for other purposes. As a result, any economic downturns in
general or in our markets, particularly those affecting industrial and
commercial users of natural gas and electricity, would have a material adverse
effect on our business, cash flows, financial condition and results of
operations.

      IF WE FAIL TO EFFECTIVELY MANAGE OUR FUTURE GROWTH, OUR ABILITY TO MARKET
      AND SELL OUR PRODUCTS AND SERVICES AND TO DEVELOP NEW PRODUCTS AND
      SERVICES MAY BE ADVERSELY AFFECTED.

      We must plan and manage our growth effectively in order to offer our
products and services and achieve revenue growth and profitability in a rapidly
evolving market. Our future growth will place a significant strain on our
management systems and resources. If we are not be able to effectively manage
our growth in the future, our business may be materially and adversely affected.

      CHANGES IN UTILITY RATE AND TARIFF STRUCTURES COULD HARM OUR BUSINESS AND
      RESULTS OF OPERATIONS.

      Some of our businesses, especially the businesses of PowerSecure and
Metretek Florida, are heavily dependent upon utility rates and tariffs.
PowerSecure and Metretek Florida develop proposals for new projects based on
utility tariffs in a region or utility company existing at that time. If the
local utility changes its tariffs, then PowerSecure's and Metretek Florida's
proposals for that region or utility company may be rendered obsolete, adversely
affecting their ability to make future sales in that region or to that specific
utility company, and this reduction in future sales could materially and
adversely affect our business and our results of operations

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

      The margins on our revenues from some of our product and service offerings
is higher than the margins on our other product and service offerings. For
example, revenues from some of Metretek Florida's AMR devices have significantly
higher margins than Metretek Florida's contract manufacturing revenues. In
addition, we cannot currently accurately estimate the margins of some of our new
and developing products and services due to their limited operating history. Our
new products and services may have lower margins than our current products and
services. If in the future we derive a proportionately greater percentage of our
revenues from lower margin products and services, then our overall margins on
our total revenues will decrease and, accordingly, will result in lower net
income, or higher net losses, and less cash flow on the same amount of revenues.

      OUR MANAGEMENT OF PRIVATE ENERGY PROGRAMS PRESENTS RISKS TO US.

      We have a subsidiary that manages and holds a minority ownership interest
in one continuing private energy program and in one discontinued private energy
program. While that subsidiary does not intend to form any new private programs,
it may from time to time repurchase interests in the continuing program or to
initiate or manage actions intended to expand its assets or activities. These
private programs were financed by private placements of equity interests raising
capital to acquire the assets and business operated by the program. Our
management of these energy programs presents risks to us, including:

      -     lawsuits by investors in these programs who become dissatisfied with
            the result of these programs, including the class action lawsuit
            pending against us that is subject to a proposed settlement;


                                       14

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

      -     annual preferred shareholder interest repurchase commitments;

      -     risks inherent in managing a program and taking significant actions
            that affect its investors;

      -     changes in the regulatory environment relating to these programs;

      -     reliance upon significant suppliers and customers by these programs;

      -     hazards of energy facilities; and

      -     changes in technology.

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

      WE DO NOT HAVE LONG-TERM PURCHASE AGREEMENTS WITH MOST OF OUR CUSTOMERS,
      AND, AS A RESULT, MOST OF OUR CUSTOMERS COULD STOP PURCHASING OUR PRODUCTS
      AND SERVICES AT ANY TIME.

      We generally do not obtain firm, long-term volume purchase commitments
from our customers, and we generally experience short lead-times for customer
orders. In addition, customer orders can be canceled and volume levels can be
reduced or delayed. We may be unable to replace canceled, delayed or reduced
orders with new business. For example, most of PowerSecure's revenues are
derived on a non-recurring, project by project basis, and there is no assurance
that its revenues and business will continue to grow.

      OUR INTERNATIONAL SALES ACTIVITIES ARE SUBJECT TO MANY RISKS AND
      UNCERTAINTIES THAT COULD ADVERSELY AFFECT OUR OPERATING RESULTS IF THEY
      MATERIALIZE.

      We market and sell some of our products and services in international
markets. Our revenues from sales into international markets were approximately
3% of our consolidated revenues in each of the past three fiscal years. One
component of our strategy for future growth involves the expansion of our
products and services into new international markets and the expansion of our
marketing efforts in our current international markets. This expansion will
require significant management attention and financial resources to establish
additional offices, hire additional personnel, localize and market products and
services in foreign markets and develop relationships with international service
providers. However, we have only limited experience in international operations,
including developing localized versions of our products and services and in
developing relationships with international service providers. We cannot provide
any assurance that we will be successful in expanding our international
operations, or that revenues from international operations will be sufficient to
offset these additional costs. If revenues from international operations are not
adequate to offset the additional expense from expanding these international
operations, our business could be materially and adversely affected.

      In addition to the uncertainty regarding our ability to generate
sufficient revenues from foreign operations and to expand our international
presence, we are exposed to several risks inherent in conducting business on an
international level that could result in increased expenses, or could limit our
ability to generate revenue, including:

      -     fluctuations in currency exchange rates;

      -     potential adverse tax consequences;

      -     adverse changes in applicable laws and regulatory requirements;

      -     export restrictions;

      -     export controls relating to technology;

      -     tariffs and other trade barriers;

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

      -     the impact of local economic conditions and practices;

      -     difficulties in staffing and managing foreign operations;


                                       15

      -     difficulties in complying with foreign regulatory and commercial
            requirements;

      -     increased costs associated with maintaining international marketing
            efforts;

      -     political and economic instability;

      -     reduced protection for intellectual property rights;

      -     cultural and language difficulties;

      -     challenges caused by distance;

      -     the potential exchange and repatriation of foreign earnings; and

      -     the localization and translation of products and services.

      Our success in expanding our international sales activities will depend in
large part on our ability to anticipate and effectively manage these and other
risks, many of which are outside of our control. Any of these risks could
materially and adversely affect our international operations and, consequently,
our operating results. We cannot provide any assurance that we will be able to
successfully market, sell and deliver our products and services in foreign
markets.

      WE MAY BE UNABLE TO SUCCESSFULLY ACQUIRE OTHER BUSINESSES, TECHNOLOGY OR
      COMPANIES, OR TO FORM STRATEGIC ALLIANCES AND RELATIONSHIPS, OR TO
      SUCCESSFULLY REALIZE THE BENEFITS OF ANY ACQUISITION OR ALLIANCE.

      In the past, we have grown by acquiring complimentary businesses,
technologies, services and products and entering into strategic alliances and
relationships 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
ongoing basis as they present themselves to facilitate our ability to enhance
our existing products, services and technology, and introduce new products,
services and technology, on a timely basis. However, we do not know if we will
be able to identify any future opportunities that we believe will be beneficial
for us. Even if we are able to identify an appropriate acquisition opportunity,
we may not be able to successfully finance the acquisition. A failure to
identify or finance future acquisitions may impair our growth and adversely
affect our business.

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

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

      -     the technologies, products or businesses that we acquire may not
            achieve expected levels of revenue, profitability, benefits or
            productivity;

      -     difficulties in retaining, training, motivating and integrating key
            personnel;

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

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

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

      -     difficulties in retaining relationships with customers, employees
            and suppliers of the acquired company;

      -     the need to implement or remediate controls, procedures and policies
            appropriate for a public company at companies that prior to the
            acquisition lacked these controls, procedures and policies;

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

      -     potential disruptions of our ongoing businesses; and

      -     unexpected costs and unknown liabilities associated with the
            acquisitions.

      For these reasons, future acquisitions could materially and adversely
affect our existing businesses. Moreover, we cannot predict the accounting
treatment of any acquisition, in part because we cannot be certain


                                       16

whether current accounting regulations, conventions or interpretations will
prevail in the future.

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

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

      IF WE FAIL TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY RIGHTS, WE
      COULD LOSE IMPORTANT PROPRIETARY TECHNOLOGY, WHICH COULD MATERIALLY AND
      ADVERSELY AFFECT OUR BUSINESS.

      Our success and ability to compete depends, in substantial part, upon our
ability to develop and protect our proprietary technology and intellectual
property rights to distinguish our products, services and technology from those
of our competitors. The unauthorized use of our intellectual property rights and
proprietary technologies by others could materially harm our business. We rely
primarily on a combination of copyright, trademark and trade secret laws, along
with confidentiality agreements, contractual provisions and licensing
arrangements, to establish and protect our intellectual property rights.
Although we hold copyrights and trademarks in our business, and we have applied
for a patent and the registration of a number of new trademarks and service
marks and intend to introduce new trademarks and service marks, we believe that
the success of our business depends more upon our proprietary technology,
information, processes and know-how than on patents or trademark registrations.
In addition, much of our proprietary information and technology may not be
patentable. We may not be successful in obtaining any patents or in registering
new marks.

      Despite our efforts to protect our intellectual property rights, existing
laws afford only limited protection, and our actions may be inadequate to
protect our rights or to prevent others from claiming violations of their
proprietary rights. Unauthorized third parties may attempt to copy, reverse
engineer or otherwise obtain, use or exploit aspects of our products and
services, develop similar technology independently, or otherwise obtain and use
information that we regard as proprietary. We cannot assure you that our
competitors will not independently develop technology similar or superior to our
technology or design around our intellectual property. 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 in the future. However, litigation could
result in significant costs or the diversion of management and financial
resources. We cannot assure you that any such litigation will be successful or
that we will prevail over counterclaims against us. Our failure to protect any
of our important intellectual property rights or any litigation that we resort
to in order to enforce those rights could materially and adversely affect our
business.

      IF WE BECOME SUBJECT TO CLAIMS OF INFRINGEMENT OF INTELLECTUAL PROPERTY
      RIGHTS OF THIRD PARTIES, WE COULD ENCOUNTER EXPENSIVE LITIGATION, BE
      LIABLE FOR SIGNIFICANT DAMAGES OR INCUR RESTRICTIONS ON OUR ABILITY TO
      SELL OUR PRODUCTS AND SERVICES.

      Although we are not aware of any present infringement of our products or
technologies on the intellectual property rights of others, we cannot be certain
that our products, services and technologies do not or in the future will not
infringe on the 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 incur substantial expenses
in litigation defending against any third party infringement claims, regardless
of their merit. Successful infringement claims against us could result in
substantial monetary liability, require us to enter into royalty or licensing
arrangements, or otherwise materially disrupt the conduct of our business. In
addition, even if we prevail


                                       17

on these claims, this litigation could be time-consuming and expensive to defend
or settle, and could result in the diversion of our time and attention, which
could materially and adversely affect our business.

      In recent years, there has been a significant amount of litigation in the
United States involving patents and other intellectual property rights. In the
future, we may be a party to litigation as a result of an alleged infringement
of others' intellectual property. These claims and any resulting lawsuits, if
successful, could subject us to significant liability for damages and
invalidation of our proprietary rights. These lawsuits, regardless of their
success, would likely be time-consuming and expensive to resolve and could
divert management's time and attention. Any potential intellectual property
litigation also could force us to do one or more of the following:

      -     stop selling, incorporating or using our products and services that
            use the infringed intellectual property;

      -     obtain from the owner of the infringed intellectual property right a
            license to sell or use the relevant technology, which license may
            not be available on commercially reasonable terms, or at all; or

      -     redesign the products and services that use the technology.

      If we are forced to take any of these actions, our business may be
seriously harmed. Although we carry general liability insurance, our insurance
may not cover potential claims of this type or may not be adequate to indemnify
us for all liability that may be imposed.

      RECENT TERRORIST ACTIVITIES AND RESULTING MILITARY AND OTHER ACTIONS COULD
      ADVERSELY AFFECT OUR BUSINESS.

      The terrorist attacks in recent years have disrupted commerce throughout
the world. In response to such attacks, the U.S. is actively using military
force to pursue those behind these attacks and initiating broader actions
against global terrorism. The continued threat of terrorism, the escalation of
military action, and heightened security measures in response to such threats
may cause future significant disruptions to commerce throughout the world. To
the extent that such disruptions affect our customers by resulting in reductions
in capital expenditures or spending on energy products, services and technology,
longer sales cycles, or deferrals or delays of orders by our customers, our
business and results of operations could be materially and adversely affected.

      WE FACE SOME RISKS THAT ARE INHERENT IN NATURAL GAS AND ELECTRICAL
      OPERATIONS.

      Some of our operations are subject to the hazards and risks inherent in
the servicing and operation of natural gas assets, including encountering
unexpected pressures, explosions, fire, natural disasters, blowouts, cratering
and pipeline ruptures, as well as in the manufacture, sale and operation of
electrical equipment such as PowerSecure's distributed generation system,
including electrical shocks, which hazards and risks 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.

      SOME OF POWERSECURE'S LONG-TERM TURN-KEY CONTRACTS SUBJECT US TO RISKS.

      Some of PowerSecure's contracts for turn-key distributed generation
projects have a term of many years, during which time some risks to its business
may arise due to its obligations under those contracts, even though PowerSecure
believes it has mitigated those risks. For example, PowerSecure is responsible
for full maintenance on the generators and switchgear during the term of the
contract, but it has set aside reserves expected to be sufficient to cover its
maintenance obligations and has purchased maintenance packages designed to cover
maintenance on the generators. In addition, changes in circumstances that were
not contemplated at the time of the contract could exposure PowerSecure to
unanticipated risks or to protracted or costly dispute resolution.


                                       18


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

      Our business operations are subject to varying degrees of federal, state,
local and foreign laws and regulations. Regulatory agencies may impose special
requirements for implementation and operation of our products, services or
technologies that may significantly impact or even eliminate some of our target
markets. We may incur material costs or liabilities in complying with government
regulations. In addition, potentially significant laws, regulations and
requirements may be adopted or imposed in the future. Furthermore, some of our
customers must comply with numerous laws and regulations. The modification or
adoption of future laws and regulations could adversely affect our business and
our ability to continually modify or alter our methods of operations at
reasonable costs. We cannot provide any assurances that we will be able, for
financial or other reasons, to comply with all applicable laws and regulations.
If we fail to comply with these laws and regulations, we could become subject to
substantial penalties which could materially and adversely affect our business.

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

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

      WE DEPEND ON SOLE SOURCE OR LIMITED SOURCE SUPPLIERS FOR SOME OF THE KEY
      COMPONENTS AND MATERIALS IN OUR PRODUCTS, WHICH MAKES US SUSCEPTIBLE TO
      SUPPLY SHORTAGES OR PRICE INCREASES THAT COULD ADVERSELY AFFECT OUR
      BUSINESS.

      We depend on sole or limited source suppliers for key components and
materials for some of our products such as generators, and if we are unable to
obtain these components on a timely basis, we will not be able to deliver our
products to customers. Also, we cannot guarantee that any of the parts or
components that we purchase, if available at all, will be of adequate quality or
that the prices we pay for these parts or components will not increase. We may
experience delays in production if we fail to identify alternate vendors, or if
any supply of components is interrupted or reduced and we have failed to
identify an alternative vendor or if there is a significant increase in the cost
of such components, each of which could materially and adversely affect our
business and operations.

                         RISKS RELATED TO 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, LIMITING YOUR ABILITY TO INFLUENCE CORPORATE
      MATTERS.

      As of June 1, 2004, our executive officers, directors and 10% or greater
stockholders beneficially owned, in the aggregate, approximately 42% of our
outstanding common stock, assuming they exercise or convert all stock options,
warrants and convertible preferred stock that hold. As a result, these
stockholders could, as a practical matter, exercise a significant level of
control over matters requiring approval by our stockholders, including the
election of directors, the approval of mergers and sales of substantially all of
our assets and other significant corporate transactions. The interests of these
stockholders may differ from your interests, and the concentration of control
may limit your ability to influence corporate matters. In addition, this
concentration of stock ownership may have the effect of discouraging, delaying
or preventing a change in control of us, adversely affect the market price of
our common stock.

      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

                                       19

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

      On June 1, 2004, 10,951,701 shares of common stock were outstanding. On
the same date, options to purchase 1,644,541 shares of common stock were
outstanding, and shares that may be acquired upon exercise of these stock
options are eligible for sale on the public market from time to time subject to
vesting. Also, on that date, 4,500 shares of Series B preferred stock
convertible into 2,070,639 shares of common stock, and warrants to purchase
2,978,727 shares of common stock, were outstanding. The resale of virtually all
of these shares are currently eligible for resale either under an available
exemption from the registration requirements of the Securities Act or are
covered by currently effective registration statements, including the
registration statement of which this prospectus is part of. The exercise or
conversion of outstanding options, warrants and other rights to purchase our
common stock will dilute the remaining ownership of other holders of our common
stock. In addition, the sale 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 such sales could occur, could cause the price of our
common stock to decline.

      CHANGES IN LAWS, REGULATIONS AND FINANCIAL ACCOUNTING STANDARDS COULD
      MATERIALLY AND ADVERSELY AFFECT OUR BUSINESS AND OUR REPORTED RESULTS OF
      OPERATIONS.

      Recently enacted and proposed changes in the laws and regulations
affecting public companies, including the Sarbanes-Oxley Act of 2002 and related
SEC regulations, may cause us to incur increased costs of compliance and result
in changes in accounting standards or accepted practices within our industry.
New laws, regulations and accounting standards, as well as the questioning of,
or changes to, currently accepted accounting practices in the technology
industry may adversely affect our reported financial results, which could have
an adverse effect on our stock price. For example, proposals have been made
concerning the expensing of employee stock options which could result in rules
or laws that could adversely affect our reported financial results and have an
adverse effect on our stock price. New rules could also make it more difficult
for us to obtain certain types of insurance, including director and officer
liability insurance, forcing us to accept reduced policy limits and coverage or
incur substantially higher costs to obtain the same or similar coverage. The
impact of these events could also make it more difficult for us to attract and
retain qualified persons to serve on our board of directors or as our executive
officers.

      IF WE ACCOUNT FOR EMPLOYEE STOCK OPTIONS USING THE FAIR VALUE METHOD AS IS
      CURRENTLY PROPOSED BY THE FINANCIAL ACCOUNTING STANDARDS BOARD, IT COULD
      SIGNIFICANTLY REDUCE OUR NET INCOME OR INCREASE OUR NET LOSS.

      There has been ongoing public debate whether stock options granted to
employees should be treated as a compensation expense and, if so, how to
properly value such charges. On March 31, 2004, the Financial Accounting
Standards Board issued an Exposure Draft, Share-Based Payment: an amendment of
FASB statements No. 123 and 95, which would require a company to recognize, as
an expense, the fair value of stock options and other stock-based compensation
to employees beginning in 2005 and subsequent reporting periods. If we elect or
are required to record an expense for our stock-based compensation plans using
the fair value method as described in the Exposure Draft, we could have
significant ongoing accounting charges, reducing any future net income or
increasing any future net losses.

      ANTI-TAKEOVER PROVISIONS IN OUR CHARTER DOCUMENTS AND UNDER DELAWARE LAW
      COULD DISCOURAGE OR PREVENT A THIRD-PARTY ACQUISITION OF OUR COMMON STOCK,
      EVEN IF AN ACQUISITION THAT STOCKHOLDERS MAY CONSIDER FAVORABLE.

      Some provisions in our second restated certificate of incorporation and
our amended and restated by-laws, as well as some provisions of Delaware law,
could have the effect of discouraging, delaying or preventing a third party from
attempting to acquire us, even if stockholders consider the transaction to be
beneficial. These provisions could also limit the price that investors might be
willing to pay in the future for shares of our common stock. These provisions
include:

      -     a classified board of directors in which only approximately
            one-third of the total board members are elected at each annual
            meeting;

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


                                       20

      -     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 the preferred stock, without any vote by or approval of
            our stockholders (other than the consent of holders of Series B
            preferred stock relating to any senior or equal ranking securities);

      -     super-majority voting requirements to effect material amendments to
            our second restated certificate and by-laws;

      -     limiting the persons who may call special meetings of stockholders;

      -     prohibiting stockholders from acting by written consent without a
            meeting;

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

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

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

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

      In addition, we have entered into employment agreements with certain
executive officers and other employees which, among other things, include
severance and changes in control provisions. The provisions could make a change
in control costly for a potential acquirer and thus discourage a take-over
attempt.

      OUR STOCKHOLDER RIGHTS AGREEMENT MAKES EFFECTING A CHANGE OF CONTROL MORE
      DIFFICULT, WHICH MAY DISCOURAGE OFFERS FOR SHARES OF OUR COMMON STOCK.

      Our board of directors has adopted an amended and restated rights
agreement. Our rights agreement may have the effect of delaying, deterring, or
preventing changes in our management or control of us, which may discourage
potential acquirers who otherwise might wish to acquire us without the consent
of the board of directors. Under the rights plan, if a person or group acquires
15% or more of our common stock, all holders of rights (other than the acquiring
stockholder) may, upon payment of the purchase price then in effect, purchase
common stock having a value of twice the purchase price. We waived the
provisions of the rights agreement with respect to the securities issued in the
May 2004 private placement and the recent conversion of Series B preferred
stock. In the event that we are involved in a merger or other similar
transaction where we are not the surviving corporation, all holders of rights
(other than the acquiring stockholder) shall be entitled, upon payment of the
then in effect purchase price, to purchase common stock of the surviving
corporation having a value of twice the purchase price. The rights will expire
on November 30, 2011, unless we extend the terms of the rights agreement or we
earlier redeem or exchange the rights. See "Description of Capital Stock -
Rights Agreement."

      WE HAVE NOT IN THE PAST AND WE DO NOT CURRENTLY INTEND TO PAY DIVIDENDS ON
      OUR COMMON STOCK, AND EVEN IF WE DID OUR ABILITY TO PAY DIVIDENDS IS
      LIMITED.

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

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

      We currently intend to retain all future earnings, if any, for use in the
operation and expansion of our business and for the servicing and repayment of
indebtedness. As a holding company with no independent operations, our ability
to pay dividends is dependant upon the receipt of dividends or other payments
from our subsidiaries. The terms of our credit facility limit our ability to pay
dividends, other than on our Series B preferred

                                       21

stock by prohibiting the payment of dividends by our subsidiaries without the
consent of the lender. In addition, the terms of our Series B preferred stock
contain certain restrictions on our ability to pay dividends on our common
stock. Future dividends, if any, will be determined by our Board of Directors,
based upon our earnings, financial condition, capital resources, capital
requirements, charter restrictions, contractual restrictions and such other
factors as our Board of Directors deems relevant.

      OUR STOCK PRICE IS SUBJECT TO EXTREME PRICE AND VOLUME FLUCTUATIONS, WHICH
      COULD ADVERSELY AFFECT AN INVESTMENT IN OUR STOCK.

      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 have been especially
volatile. A number of factors could cause wide fluctuations in the market price
and trading volume of our common stock in the future, including:

      -     actual or anticipated variations in our results of operations;

      -     announcements of technological innovations;

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

      -     the receipt or loss of significant customer orders;

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

      -     conditions or trends in the energy and technology industries in
            general, and in the particular markets we service;

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

      -     the lower coverage by securities analysts and the media of issuers
            with securities trading on the OTC Bulletin Board;

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

      -     changes in the market valuation of other energy or technology
            companies;

      -     additions or departures of key personnel;

      -     commencement of new and changes in existing litigation;

      -     general economic, business and market conditions; and

      -     sales of our common stock by directors, executive officers and
            significant stockholders.

      Many of these factors are beyond our control. The occurrence of any one or
more of these factors could cause the market price of our common stock to fall,
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. Securities litigation
is often expensive and could divert 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 SHARES OF PREFERRED STOCK WHICH COULD DILUTE THE
      INTERESTS OF HOLDERS OF OUR COMMON STOCK.

      The terms of our Series B preferred stock do not limit the issuance of
additional series of preferred stock ranking junior to the Series B preferred
stock, but do require the approval of the holders of a majority of the
outstanding shares of Series B preferred stock to issue any stock senior to or
on a parity with the Series B preferred stock. The issuance of additional shares
of preferred stock, even if it ranks junior to the Series B preferred stock,

                                       22

could dilute the interest of holders of our common stock.

      THERE MAY NOT BE A LIQUID MARKET FOR OUR COMMON STOCK, WHICH COULD LIMIT
      THE ABILITY OF A PURCHASE OF OUR COMMON STOCK TO RESALE ANY SHARES THAT
      ARE ACQUIRED.

      Our common stock is currently traded on the OTC Bulletin Board. This
market generally has less liquidity than the national exchanges or the Nasdaq
Stock Market, and certain institutional investors are precluded from acquiring
or holding securities that is only traded in this market. Accordingly, a person
who purchases any shares under this prospectus may be limited in his ability to
resell those shares. We cannot provide any assurance that persons who purchases
shares under this prospectus will be able to sell those shares at prices or
times that are desirable to that person.

assumptions, the receipt of new information, the occurrence of future or
unanticipated events, circumstances or conditions or otherwise.

                                 USE OF PROCEEDS

      We will not receive any proceeds from the sale of the shares offered under
this prospectus by the selling securityholders. All proceeds from the sale of
the shares offered under this prospectus hereby will be for the account of the
selling securityholders listed below in "Selling Securityholders."

      However, because 2,262,297 shares of common stock offered by this
prospectus are issuable upon the exercise of warrants held by the selling
securityholders, we will receive the proceeds, if any, from any exercise of the
warrants by the selling securityholders in cash. If all the warrants are
exercised in cash, then we will receive aggregate gross proceeds of
approximately $7.3 million, assuming the exercise prices of the warrants are not
adjusted. See "Description of Capital Stock - Warrants." We anticipate that the
proceeds from any cash exercises of warrants will be used for general corporate
purposes, which may include working capital, capital expenditures, and the
repayment of indebtedness, or for acquisitions of businesses, technology or
assets and repurchases of securities. We cannot assure you that any of the
warrants will be exercised in cash or, if any warrants are exercised, when these
exercises will occur.

                             SELLING SECURITYHOLDERS

      References in this prospectus to the selling securityholders include the
persons listed in the table below and any donees, pledgees, transferees or other
successors-in-interest selling shares received from a selling securityholder as
a gift, pledge, partnership distribution or other transfer after the date of
this prospectus.

      All of the shares of common stock offered by the selling securityholders
under this prospectus were issued to, or are issuable upon the exercise of
warrants issued to, the selling securityholders in private placement
transactions exempt from the registration requirements of the Securities Act
under Section 4(2) of the Securities Act and Rule 506 of Regulation D
promulgated under the Securities Act.

      We have registered the resale by the selling securityholders of the shares
offered under this prospectus under their registration rights. In connection
with the issuance in the May 2004 private placement of an aggregate of 3,510,548
shares of common stock and warrants to purchase 1,053,164 shares of common
stock, we entered into a registration rights agreement. In addition, we agreed
to register the resale of 55,871 of the shares of common stock, and 1,209,133
shares of common stock issuable upon the exercise of warrants, issued to certain
holders who converted 2,500 shares of Series B preferred stock in May 2004.
Under the registration rights agreement, we agreed to register the public resale
of all shares of common stock issued or issuable in connection with the private
placement by filing a registration statement with the SEC and keeping the
registration statement effective until the earliest of the following:

      -     five years after the registration statement becomes effective;

      -     such time as all such shares have been publicly resold;

      -     such time as all such shares may be sold under Rule 144(k) under the
            Securities Act.

                                       24

      The actual number of shares of common stock covered by this prospectus,
and included in the registration statement of which this prospectus is a part,
includes additional shares of common stock that may be issued as a result of
stock splits, stock dividends or similar transactions relating to our
securities.

      The following table sets forth, as of June 1, 2004, except as otherwise
stated in the notes to the table, the following information based on the most
recent information provided to us by or on behalf of the selling
securityholders:

      -     the name of each selling securityholder;

      -     the number of shares and the percent of common stock beneficially
            owned by each selling securityholder;

      -     the number of shares that may be offered for sale from time to time
            by each selling securityholder under this prospectus; and

      -     the number of shares and the percentage of common stock to be
            beneficially owned by each selling securityholder assuming the sale
            of all the shares offered under this prospectus.

      The shares offered under this prospectus may be sold from time to time by
the selling securityholders. We are not aware of any current agreement,
arrangement or understanding by the selling securityholders with respect to the
sale of any shares offered under this prospectus. Each selling securityholder
may decide to sell under this prospectus all, some or none of the shares listed
in the table. Accordingly, we cannot estimate the number of shares that the
selling securityholders will beneficially own after completion of this offering.
In addition, the selling securityholders identified below may have sold,
transferred or otherwise disposed of all or a part of their common stock since
the date on which they provided the information regarding their beneficial
ownership.

      Beneficial ownership is determined under the rules and regulations of the
SEC and generally includes voting or investment control, but is not necessarily
indicative of beneficial ownership for any other purpose. Unless otherwise
indicated below, to our knowledge, each selling securityholder named in the
table below has sole voting and investment power with respect to the shares
shown in the table, except as provided by applicable community property laws. In
computing the number of shares of common stock and the percent of outstanding
common stock beneficially owned by a selling securityholder, beneficial
ownership includes any shares issuable under options, warrants, conversion
rights and other rights that are exercisable on or within 60 days of June 1,
2004. Such shares, however, are not included for purposes of computing the
beneficial ownership of any other selling securityholder. The percentage of
beneficial ownership is based upon 10,951,701 shares of common stock outstanding
on June 1, 2004.

      Information about the selling securityholders may change over time. Any
changed information will be contained in one or more prospectus supplements.
None of the selling securityholders has held any position, office or other
material relationship with us or any of our affiliates within the past three
years, other than as a result of the ownership of our shares or other
securities, except that Roth Capital Management, LLC acted as our placement
agent in the May 2004 private placement.

                              PLAN OF DISTRIBUTION

      The selling securityholders and any of their pledgees, donees,
transferees, assignees and other successors-in-interest may, from time to time,
sell any or all of the shares of common stock offered under this prospectus on
any

                                       31

stock exchange, market or trading facility on which the shares are traded or in
private transactions. These sales may be at fixed or negotiated prices. The
selling securityholders may use any one or more of the following methods when
selling shares:

      -     ordinary brokerage transactions and transactions in which the
            broker-dealer solicits investors;

      -     block trades in which the broker-dealer will attempt to sell the
            shares as agent but may position and resell a portion of the block
            as principal to facilitate the transaction;

      -     purchases by a broker-dealer as principal and resale by the
            broker-dealer for its account;

      -     an exchange distribution in accordance with the rules of the
            applicable exchange;

      -     privately negotiated transactions;

      -     to cover short sales made after the date that the registration
            statement of which this prospectus is a part is declared effective
            by the SEC;

      -     through the writing or settlement of options or other hedging
            transactions, whether through an options exchange or otherwise;

      -     broker-dealers may agree with the selling securityholders to sell a
            specified number of such shares at a stipulated price per share;

      -     a combination of any such methods of sale; and

      -     any other method permitted by applicable law.

      The selling securityholders may also sell any of the shares offered under
this prospectus that qualify for sale under Rule 144 under the Securities Act,
rather than under this prospectus.

      Broker-dealers engaged by the selling securityholders may arrange for
other brokers-dealers to participate in sales. Broker-dealers may receive
commissions or discounts from the selling securityholders (or, if any
broker-dealer acts as agent for the purchaser of shares, from the purchaser) in
amounts to be negotiated. The selling securityholders do not expect these
commissions and discounts to exceed what is customary in the types of
transactions involved.

      The selling securityholders may from time to time pledge or grant a
security interest in some or all of the shares owned by them and, if they
default in the performance of their secured obligations, the pledgees or secured
parties may offer and sell shares of common stock from time to time under this
prospectus, or under a supplement or an amendment to this prospectus under Rule
424(b)(3) or other applicable provision of the Securities Act supplementing or
amending the list of selling securityholders to include the pledgee, transferee
or other successors in interest as selling securityholders under this
prospectus.

      In connection with the sale of our shares, the selling securityholders may
enter into hedging transactions with broker-dealers or other financial
institutions, which may in turn engage in short sales of the shares in the
course of hedging the positions they assume. The selling securityholders may
also sell shares of our common stock short and deliver these securities to close
out their short positions, or loan or pledge the shares to broker-dealers that
in turn may sell these securities. The selling securityholders may also enter
into option or other transactions with broker-dealers or other financial
institutions or the creation of one or more derivative securities which require
the delivery to such broker-dealer or other financial institution of shares
offered by this prospectus, which shares such broker-dealer or other financial
institution may resell pursuant to this prospectus (as supplemented or amended
to reflect such transaction).

      Upon being notified in writing by a selling securityholders that any
material arrangement has been entered into with a broker-dealer for the sale of
shares through a block trade, special offering, exchange distribution or

                                       32

secondary distribution or a purchase by a broker or dealer, we will file a
supplement to this prospectus, if required, pursuant to Rule 424(b) under the
Securities Act, disclosing:

      -     the name of each such selling securityholders and of the
            participating broker-dealer(s);

      -     the number of shares involved;

      -     the price at which such the shares were sold;

      -     the commissions paid or discounts or concessions allowed to such
            broker-dealer where applicable;

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

      -     other facts material to the transaction.

      In addition, upon being notified in writing by a selling securityholders
that a donee, pledges, transfers and other successor interests intends to sell
more than 500 shares of common stock, we will file a supplement to this
prospectus, if then required in accordance with applicable securities law. Any
prospectus supplement may also add, update or change any information contained
in this prospectus, including information with the respect to the distribution
of the shares.

      The selling securityholders also may transfer the shares of common stock
in other circumstances, in which case the transferees, pledgees or other
successors in interest will be the selling beneficial owners for purposes of
this prospectus.

      The selling securityholders and any broker-dealers or agents that are
involved in selling the shares may be deemed to be "underwriters" within the
meaning of the Securities Act in connection with such sales. In such event, any
commissions received by such broker-dealers or agents and any profit on the
resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act. Discounts, concessions,
commissions and similar selling expenses, if any, that can be attributed to the
sale of securities will be paid by the selling securityholders and/or the
purchasers. Each selling securityholders has represented and warranted to us
that it acquired the securities subject to this registration statement in the
ordinary course of such selling securityholders business and, at the time of its
purchase of such securities such selling securityholders had no agreements or
understandings, directly or indirectly, with any person to distribute any such
securities.

      We have advised each selling securityholder that it may not use shares
registered on the registration statement of which this prospectus is a part to
cover short sales of common stock made prior to the date on which the
registration statement of which this prospectus is a part shall have been
declared effective by the SEC. The selling securityholders will be responsible
to comply with the applicable provisions of the Securities Act and Exchange Act,
and the rules and regulations thereunder promulgated, including, without
limitation, the anti-manipulation provisions of Regulation M, as applicable to
such selling securityholders in connection with resales of their respective
shares under this prospectus, which provisions may restrict activities of the
selling securityholders and limit the timing of purchases and sales of shares by
the selling securityholders.

      If the selling securityholders use this prospectus for any sale of shares,
they will be subject to the prospectus delivery requirements of the Securities
Act. We do not intend, and we assume no obligation, to deliver any copies of
this prospectus.

      The shares will be sold only through registered or licensed brokers or
dealers if required by applicable state securities laws. In addition, in some
states the shares 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.

      We have agreed to pay all expenses related to the registration of the sale
of the shares offered under this prospectus by the selling securityholders. The
selling securityholders will pay all commissions, discounts, concessions and
other compensation and selling expenses attributable to the sale of the shares.
We have agreed to

                                       33

indemnify the selling securityholders against liabilities related to the
registration of the shares, 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 securityholders may agree to
indemnify any broker-dealer or agent that participates in transactions involving
sales of the shares against liabilities related to the offer and sale of the
shares, 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.

      Neither we nor, to our knowledge, any selling securityholder has engaged
any underwriter, broker, dealer or agent in connection with the distribution of
the shares offered under this prospectus. The selling securityholders will act
independently of us and each other, except as discussed in the notes to the
table in "Selling Securityholders", in making decisions regarding the timing,
manner and size of each sale. The selling securityholders are not obligated to,
and we cannot assure you that the selling securityholders will, sell all or any
of the shares 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.

      The following summary of the material terms of our capital stock is not
intended to be complete but is qualified in its entirety by reference to our
second restated certificate of incorporation, our amended and restated by-laws
and our amended and restated rights agreement, each as in effect as of the date
of this prospectus and the provisions of Delaware law. Our second restated
certificate, by-laws and rights agreement are exhibits to the registration
statement of which the prospectus is a part.

COMMON STOCK

      The holders of our 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 holders of any outstanding shares 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 shares of preferred stock, the holders of common
stock are entitled to receive any dividends that may be declared from time to
time by our board of directors out of funds legally available therefore. Upon
our liquidation, dissolution or winding up, the holders of our common stock are
entitled to share ratably in all assets remaining after payment of all debts and
other liabilities, depending upon the liquidation preferences of any shares of
preferred stock 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 our common stock. All outstanding shares of our common stock are fully paid
and nonassessable. The rights of holders of our common stock depend upon, and
might be adversely affected by, the rights of any shares of preferred stock
which we have issued or may issue in the future.

PREFERRED STOCK

      AUTHORIZATION. Under our second restated certificate, our board of
directors has the authority, without further action by the stockholders, other
than the approval of holders of Series B preferred stock described below 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, our board of directors
could 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 could adversely affect the market
price of our common stock. Except for the issuance of the Series C preferred
stock as required by 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."

                                       34

      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:

      -     cumulative quarterly dividends in preference to the holders of
            common stock equal to the greater of $4.00 per share or 100 times
            the dividend paid per share to holders of common stock;

      -     100 votes per share; and

      -     a preference on liquidation equal to the greater of $16.00 per share
            or 100 times the amount payable per share to the holders of common
            stock.

SERIES B PREFERRED STOCK

      As of June 1, 2004, 4,500 shares of our Series B preferred stock, par
value $.01 per share, were outstanding. The shares of our Series B preferred
stock are validly issued, fully paid and non-assessable. The holders of our
Series B preferred stock have no preemptive or preferential right to purchase or
subscribe for stock, obligations, warrants or any other of our securities of any
class. The Series B preferred stock is not listed, quoted or traded on any
public market.

      RANKING. Our Series B preferred stock ranks senior to our common stock and
to our Series C preferred stock with respect to dividend rights and rights on
liquidation, dissolution and winding-up. While any shares of Series B preferred
stock are outstanding, we may not issue any equity securities, or securities
exchangeable for or convertible into equity securities or measured by our
earnings or profit, other than our Series C preferred stock, that rank senior to
or on a parity with the Series B preferred stock as to liquidation, dividend and
redemption rights without the consent of the holders of at least a majority of
the outstanding shares of Series B preferred stock then outstanding, voting as a
single class. We may, however, without the consent of any holder of Series B
preferred stock, create or increase the amount of any class of capital stock
that ranks junior to the Series B preferred stock with respect to liquidation,
dividend and redemption rights.

      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. These
dividends are cumulative and accrue from the most recent date on which the
dividends have been paid or, if no dividends have been paid, from the date of
the original issuance of the Series B preferred stock. 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 shares of common stock unless at the same time we declare or
pay the same dividend on Series B preferred stock on the basis of the number of
shares of common stock into Series B preferred stock held is then convertible.

      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:

      -     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

      -     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 Series B preferred stock as to
            dividend, liquidation or redemption rights.

      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 Series B preferred stock at a redemption price, payable in cash,

                                       35

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 their shares of Series B preferred stock redeemed in connection
with, or to participate in, any significant transactions, such as certain
mergers and consolidations, sales of substantially all of our assets, or other
significant stock purchases or repurchases.

      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:

      -     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

      -     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.

      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 our 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. 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 outstanding shares of Series B
preferred 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. We may exercise this right to
redeem the Series B preferred stock only if in the time between our giving of
the notice of redemption and the date on which redemption is to occur a
registration statement is in effect covering the sale by the holders of Series B
preferred stock of all shares of common stock issuable upon conversion of the
Series B preferred stock.

      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

                                       36

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. Since March 13, 2000, the holders of Series B preferred
stock have 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.

      As 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:

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

      -     liquidate or dissolve;

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

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

      -     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:

      -     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;

      -     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

      -     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 is convertible,
in whole or in part, at any time 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 current conversion price
of the Series B preferred stock is $3.0571 per share of

                                       37

common stock, subject to adjustment to prevent dilution from certain events,
such as organic corporate events affecting the common stock or issuances of
shares of options, warrants or rights to purchase shares at a price or
conversion price, as applicable, per share of common stock less than the greater
of the market price of the common stock or the conversion price of the Series B
preferred stock in effect immediately before the issuance, other than certain
excluded shares, options, warrants and other rights.

WARRANTS

      As of June 1, 2004, warrants to purchase 2,978,727 shares of our common
stock with exercise prices ranging from $2.47 to $88.96 were outstanding.

      In the private placement we completed in February 2000, we issued 700,000
warrants, each warrant entitling the holder to purchase one share of common
stock at a current exercise price of $3.474 until December 9, 2004. The exercise
price may be adjusted under the anti-dilution provisions of the warrants, which
are substantially the same as the anti-dilution provisions of the Series B
preferred stock described above in "--Series B Preferred Stock - Conversion
Rights". Instead of paying the exercise price in cash, holders may exercise
these warrants by delivering to us shares of common stock with a fair market
value equal to the exercise price. Alternatively, holders of these warrants may
make a cashless exercise of these 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.

      In the May 2004 private placement, we issued warrants to purchase 702,109
shares of common stock to investors and 351,055 shares of common stock to the
placement agent. Each warrant is exercisable at an exercise price of $3.41 per
share until May 2009. The warrants issued to investors are exercisable on a
cashless basis if no registration statement is effective at the time of
exercise, which means that upon exercise the holder of the warrant will be
entitled to recover a net number of shares of common stock without paying any
cash, based on the market price of the common stock at the time of exercise. The
warrants issued to the placement agent may be exercised on a cashless basis at
any time. In May 2004, we also issued to the holders of Series B preferred
stock, who converted some of their shares of Series B preferred stock into
shares of common stock, warrants to purchase 1,209,133 shares at common stock
exercisable at an exercise price of $3.0571 per share until June 9, 2005. All
warrants issued in May 2004 may be redeemed by us on 30 days prior written
notice after May 3, 2005, at a price of $.01 per warrant, if the average trading
price of our common stock for any 30 consecutive trading day period is greater
than or equal to twice the exercise price. In addition, the exercise price of
all warrants issued in May 2004 is subject to adjustment to prevent dilution.
This prospectus covers the shares issued upon the exercise of these warrants.

      In July 1999, we issued warrants to purchase 15,000 shares of common stock
at exercise prices of $2.47 and $4.50 per share exercisable until July 19, 2004
for consulting and advisory services rendered to us by the warrant holder.

      When we acquired Metretek Florida in 1994, we issued warrants to purchase
our common stock to the holders of then outstanding warrants to purchase
Metretek Florida capital stock. As of June 1, 2004, warrants to purchase an
aggregate of 1,430 shares of common stock were outstanding, with an expiration
date of June 30, 2004 and with an exercise price of $88.96 per share.

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

      Certain provisions of Delaware law, 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 another person from attempting to
acquire us or engage in a change in control transaction, including those
attempts that might result in a premium over the market price for the shares
held by stockholders. These provisions which are summarized below, are expected
to discourage coercive takeover practices and inadequate takeover bids. These
provisions are also designed to encourage person seeking to acquire control of
us to first negotiate with our board of directors. We believe that the benefits
of increased protection of our potential ability to negotiate with an unfriendly
or unsolicited acquired outweigh the disadvantages of discouraging a proposal to
acquire us because negotiation of these proposals could result in an improvement
of their terms.

      BUSINESS COMBINATIONS WITH RELATED PERSON. 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

                                       38

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 REQUIREMENTS. 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.

      LIMITS ON ABILITY OF SHAREHOLDER TO ACT BY WRITTEN CONSENT OR TO CALL
SPECIAL MEETINGS. Our second restated certificate eliminates the ability of
stockholders to act by written consent. Our by-laws 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 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:

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

      -     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 "--Series B Preferred Stock -
Voting Rights" above. 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.

      UNDESIGNATED PREFERRED STOCK. The ability authorize undersigned preferred
stock makes it possible for our board of directors to issue preferred stock with
voting or other rights or preferences that could impede the success of any
attempt to acquire us. These and other provisions may have the effect of
deferring hostile takeovers or delaying changes in control or management of our
company.

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:

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

                                       39

      -     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

      -     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:

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

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

      -     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;

      -     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

      -     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 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 has been filed with the SEC.

      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 $15.00.

      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 November 30, 2011, unless the term of the rights agreement
is extended by us or the rights are earlier redeemed or exchanged by us.

                                       40

      After a distribution date occurs, each right will entitle the holder to
purchase one one-hundredths of a share of Series C preferred stock at a purchase
price of $15.00 per one one-hundredth of a share, subject to adjustment. 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 $30.00 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 $30.00, if
any of the following occurs:

      -     we merge with or consolidate into another entity;

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

      -     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". 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 securities issued or issuable in connection with
the private placement we completed in February 2000 and in our May 2004 private
placement and the May 2004 conversion of Series B preferred stock, or by
exercising or converting any convertible securities included in these
transactions, 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
$0.01 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.

      At any time prior to the distribution date, we may, without the approval
of any holder of the rights, supplement or amend any provision of the rights
agreement. After the distribution date, the rights agreement may be amended
only:

      -     to cure ambiguities;

      -     to correct inconsistent provisions;

      -     to shorten or lengthen any time period under the rights agreement;
            or

      -     in ways that do not adversely affect the holders of the rights,
            other than an acquiring person or adverse person.

      From and after the distribution date, the rights agreement may not be
amended to lengthen:

      -     a time period relating to when the rights may be redeemed at any
            time when the rights are not then redeemable; or

      -     any other time period unless the lengthening is for the purpose of
            protecting, enhancing or clarifying the rights of, and/or the
            benefits to, the holders of the rights, other than an acquiring
            person or adverse person.

      The prices and amounts above will be appropriately adjusted for stock
splits and other changes to our capital stock.

      Our rights agreement contain 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.

                                       41

TRANSFER AGENT AND REGISTRAR

      The transfer agent and registrar for the common stock is ComputerShare
Trust Company.

LISTING

      Our common stock is traded on the OTC Bulletin Board under the trading
symbol "MTEK".

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 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 any breach of fiduciary duty as a
director, except for liability:

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

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

      -     under Section 174 of the DGCL, relating to unlawful payments of
            dividends or unlawful stock purchases or redemptions; and

      -     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.

                                       42

      The limitation of liability and indemnification provisions in our
certificate of incorporation and bylaws may discourage stockholders from
bringing a lawsuit against our directors for breach of their fiduciary duty.
They may also reduce the likelihood of derivative litigation against our
directors and officers, even though an action, if successful, might benefit us
and other stockholders. Furthermore, a stockholder's investment may be adversely
affected to the extent that we pay the costs of settlement and damage awards
against directors and officers as required by these indemnification provisions.
At present, there is no pending litigation or proceeding involving nay of our
directors, officers or employees regarding which indemnification is sought, and
we are not aware of any threatened litigation that may result in claims for
indemnification.

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

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

                                      II-1

violation of law; (iii) under Section 174 of the DCGL, 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.

ITEM 17.  UNDERTAKINGS.

(a)   The undersigned Registrant hereby undertakes:

      (1)   To file, during any period in which offers or sales are being made,
            a post-effective amendment to this Registration Statement:

            (i)   To include any prospectus required by Section 10(a)(3) of the
                  Securities Act of 1933;

                                      II-6

            (ii)  To reflect in the prospectus any facts or events arising after
                  the effective date of the Registration Statement (or the most
                  recent post-effective amendment thereof) which, individually
                  or in the aggregate, represent a fundamental change in the
                  information set forth in this Registration Statement.
                  Notwithstanding the foregoing, any increase or decrease in
                  volume of securities offered (if the total dollar value of
                  securities offered would not exceed that which was registered)
                  and any deviation from the low or high end of the estimated
                  maximum offering range may be reflected in the form of
                  prospectus filed with the Commission pursuant to Rule 424(b)
                  if, in the aggregate, the changes in volume and price
                  represent no more than 20 percent change in the maximum
                  aggregate offering price set forth in the "Calculation of
                  Registration Fee" table in the effective Registration
                  Statement; and

            (iii) To include any material information with respect to the plan
                  of distribution not previously disclosed in the Registration
                  Statement or any material change to such information in the
                  Registration Statement;

            provided, however, that paragraphs (i) and (ii) do not apply if the
            information required to be included in a post-effective amendment by
            those paragraphs is contained in periodic reports filed with or
            furnished to the Commission by the Registrant pursuant to Section 13
            or Section 15(d) of the Securities Exchange Act of 1934 that are
            incorporated by reference in the Registration Statement.

      (2)   That, for the purpose of determining any liability under the
            Securities Act of 1933, each such post-effective amendment 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.

      (3)   To remove from registration by means of a post-effective amendment
            any of the securities being registered which remain unsold at the
            termination of the offering.

(b)   The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) 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.

(c)   Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant 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 Registrant 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.

                                      II-7

                                   SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-2 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Denver, State of Colorado on June 3, 2004.
