      relating to the securities covered by Registration Statement on Form S-2
      (No. 333-116155) filed by the Registrant on June 2, 2004 and declared
      effective on June 24, 2004, and in a prospectus relating to the securities

EXPLANATORY NOTE

         This Registration Statement constitutes a post-effective amendment to
two registration statements that Registrant has previously filed.

         Registrant has previously filed a Registration Statement on Form
S-2 (No. 333-116155) relating to the sale of 5,828,716 shares of common stock by
certain selling securityholders. This is being filed as Post-Effective Amendment
No. 1 to such Form S-2, in order to comply with the date of information
requirements in Section 10(a)(3) of the Securities Act of 1933, and in order to
eliminate those shares previously sold by such selling securityholders. A total
of 4,028,584 shares of common stock continue to be eligible for offer and sale
under Registration Statement No. 333-116155.

         In addition, Registrant has previously filed a Registration Statement
on Form S-3 (No. 333-96369) relating to the sale of 3,991,079 shares of common
stock and 7,000 shares of Series B preferred stock by certain selling
securityholders. This is being filed as Post-Effective Amendment No. 1 to such
Form S-3 on Form S-2, because the Registrant is no longer eligible to use Form
S-3 but is eligible to use Form S-2, and because Registrant is eliminating those
shares which Registrant is no longer required to register. A total of 1,753,260
shares of common stock continue to be eligible for offer and sale under
Registration Statement No. 333-96369.

         A total of 6,282,816 shares of common stock, constituting the sum of
the shares of common stock continuing to be eligible for offer and sale under
Registration Statement No. 333-116155 and Registration Statement No. 333-96369
are covered by the prospectus included in this Registration Statement.

         Pursuant to Rule 429 under the Securities Act of 1933, the prospectus
included in this Registration Statement is a combined prospectus which relates
to Registration Statement No. 333-116155 and Registration Statement No.
333-96369, and upon effectiveness this Registration Statement will also
constitute Post-Effective Amendment No. 1 to Registration Statement No.
333-116155 and Post-Effective Amendment No. 1 to Registration Statement No.
333-96369 on Form S-2.

                           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.

      Until recently, Metretek Florida had also provided contract manufacturing
services through its subsidiary, Metretek Contract Manufacturing Company, Inc.
These contract manufacturing services were discontinued during 2004, and
Metretek Florida's contract manufacturing business and most of its contract
manufacturing assets were sold to InstruTech Florida, LLC on December 30, 2004.

      In addition to these subsidiaries, Marcum Gas Transmission, Inc., a
subsidiary of ours based in Denver, Colorado, owns an approximate 26% economic
interest in an unconsolidated business, Marcum Midstream 1995-2 Business Trust,
which we refer to as MM 1995-2. MM 1995-2 operates four production water
disposal facilities located in northeastern Colorado.

      In this prospectus, references to "Metretek", "company", "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 Avenue, Suite 660, Denver, Colorado 80203, and our telephone number
at those offices is (303) 785-8080. Our Internet website address is
www.metretrek.com. Information contained on our website is not incorporated into
this prospectus.

BUSINESS STRATEGY

      Our business strategy is to position ourself 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.

                                       3


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.

      -     In 1994, we acquired Metretek Florida.

      -     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 a process control and switchgear design and
            manufacturing firm as part of PowerSecure's growth strategy.

      -     In 2003, we commenced the development of the cellular network
            interface and InvisiConnect(TM) series of products, which are
            machine-to-machine connection solutions for wireless network
            technology, to enhance the product, service and technology offerings
            of Metretek Florida.

      -     In 2004, we significantly increased our economic interest in MM
            1995-2 and we acquired the minority interest in PowerSecure.

      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.

                                  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 all of 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 AND INDUSTRY

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

      We have incurred net losses in each prior year of our operations since our
inception, including a net loss attributable to common shareholders of
approximately $4.5 million in fiscal 2004. As of December 31, 2004, we had an
accumulated deficit of approximately $58.5 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. There is no
guarantee that our future revenues will grow significantly, if at all. Moreover,
while we will no longer continue to accrue the preferred stock deemed
distribution in future fiscal years, we may continue to incur expenses in excess
of revenues, including significant costs in developing and expanding the
distributed generation business of PowerSecure and the telemetry business of
Metretek Florida. 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.

      WE MAY REQUIRE A SUBSTANTIAL AMOUNT OF ADDITIONAL FUNDS TO FUND OUR
      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.

      We may need to obtain additional capital to fund our capital obligations
and to finance the development and expansion of our businesses. For example, we
will need substantial additional capital to expand the shared savings business
of PowerSecure, in order to fund our acquisition of capital equipment for
distributed generation systems to be owned by PowerSecure, and to finance the
development of Metretek Florida's telemetry business. Further, under the
settlement agreement in connection with a class action lawsuit, we are required
to make payments on a $3.0 million promissory note in the annual amount of
$750,000 plus interest through June 30, 2008. 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 depend on or ability 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. In addition, we continually evaluate opportunities to improve our
credit facilities, through increased credit availability, lower debt costs or
other more favorable terms. We cannot provide any assurance that we will be able
to raise additional capital or replace our current credit facilities when needed
or desired, or that the terms of any such financing will be favorable to us and
our stockholders.

      Our current credit arrangement is the $3,260,000 credit facility, which is
currently set to mature in 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 December 31, 2004, we had an aggregate loan availability
under the credit facility of $3,260,000, of which $2,621,000 had been borrowed,
leaving $639,000 available for future use. The amount of our loan availability,
as well as the amount borrowed under the credit facility, will change in the
future depending on our asset base, our liquidity and our capital requirements.

      Our current credit facility has a number of financial covenants that our
subsidiaries must satisfy. Our ability

                                       5


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 the 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 financial condition.

      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 our lender. 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 our lender, if its
consent is required. Our inability to obtain sufficient additional capital on a
timely basis on favorable terms could have a material adverse effect on our
business, financial condition and results of operations.

      WE HAVE BEEN SUBJECT TO LAWSUITS IN THE PAST, AND IF IN THE FUTURE WE
      BECOME SUBJECT TO LAWSUITS, AND IF ANY OF THOSE LAWSUITS ARE SUCCESSFULLY
      PROSECUTED AGAINST US, OUR BUSINESS, FINANCIAL CONDITION AND RESULTS OF
      OPERATIONS COULD BE MATERIALLY AND ADVERSELY AFFECTED.

      We have been subject to lawsuits in the past that have had a material
impact on us. For example, during fiscal 2004, we settled a class action lawsuit
against us. In the future we may become 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 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 and any of which may cause
the trading price of our common stock to fluctuate. 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 obtain adequate supplies of key components and materials
      for our products on a timely and cost-effective basis;

   -  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 telemetry offerings;

   -  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;

                                       6


   -  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;

   -  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.

      Our revenues and other operating results are heavily dependant upon the
volume and timing of customer orders and payments and the date of product
delivery. The timing of large individual sales is difficult for us to predict.
Because our operating expenses are based on anticipated revenues and because a
high percentage of these are relatively fixed, a shortfall or delay in
recognizing revenue could cause our operating results to vary significantly from
quarter-to-quarter and could result in significant operating losses in any
particular quarter. If our revenues fall below our expectations in any
particular quarter, we may not be able to reduce our expenses rapidly in
response to the shortfall, which could result in us suffering significant
operating losses in that quarter.

      Due to 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 fall below
the expectations of public market analysts and investors, causing the trading
price of our common stock to decline.

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

      Our business strategy includes the development and expansion of new
businesses and product lines from time to time, including PowerSecure's shared
savings programs and Metretek Florida's telemetry business. 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 Report. 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;

                                       7


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

      -     implement an effective marketing strategy to promote awareness of
            our new businesses, 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 CURRENT CREDIT FACILITY AND
      THE CLASS ACTION SETTLEMENT COULD LIMIT HOW WE CONDUCT OUR BUSINESS AND
      OUR ABILITY TO RAISE ADDITIONAL CAPITAL.

      The terms of our current credit facility and the class action settlement
contain financial and operating covenants that place restrictions on our
activities and limit the discretion of our management. These covenants place
significant restrictions on our ability to:

      -     incur additional indebtedness;

      -     create liens or other encumbrances;

      -     issue or redeem 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 of 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.

      In addition, on several occasions during fiscal 2004, including the fourth
quarter of fiscal 2004, Metretek Florida was in violation of certain financial
covenants under its credit agreement. Although in each case we received a waiver
from the lender, there can be no assurance that such a waiver will be available
on acceptable terms in the event of a future default. If a default is declared
and not waived or cured, the entire indebtedness then owed under the credit
facility could be accelerated, and we may not be able to repay it. In addition,
if the credit facility matures and is not renewed, we may not be able to obtain
successor financing on acceptable terms. The need to comply with the terms of
our debt obligations may also limit our ability to obtain additional financing
and our flexibility in planning for or reacting to changes in our business. 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.

      WE ARE DEPENDENT UPON THE SUCCESS OF THE BUSINESS OF INSTRUTECH FLORIDA,
      WHICH ACQUIRED THE METRETEK FLORIDA CONTRACT MANUFACTURING BUSINESS, FOR
      THE REPAYMENT AND RECOVERY OF SIGNIFICANT AMOUNTS RESULTING FROM THE SALE
      AND DISCONTINUANCE OF OUR CONTRACT MANUFACTURING BUSINESS.

      During the third quarter of 2004, our board of directors approved a plan
to discontinue the contract manufacturing business of Metretek Florida and to
sell all of its contract manufacturing assets. On December 30, 2004, Metretek
Florida sold its contract manufacturing business and most of the related assets
to InstruTech Florida.

                                       8


In connection with this sale, InstruTech Florida issued to Metretek Florida a
promissory note in the amount of $780,000 that is repayable solely out of 50% of
the net cash flow of InstruTech Florida, without any further recourse. If at
least 30% of the note is not repaid prior to December 31, 2007, then we have
agreed with InstruTech Florida to negotiate in good faith on whether to extend
the maturity of the note or whether InstruTech Florida should return the
purchased equipment to us. In addition, in connection with the sale to
InstruTech Florida, we agreed to provide working capital in an amount of up to
$150,000 in the form of a bridge loan to InstruTech Florida for a period of six
months ending June 30, 2005. Repayment of any amounts advanced under the bridge
loan are repayable solely from 75% of the monthly positive cash flow from
operations of InstruTech Florida. InstruTech Florida has also agreed to purchase
Metretek Florida's remaining contract manufacturing inventory, which was
$369,000, net of reserves, as of December 31, 2004, on an as needed basis at
fair value. The assets of the discontinued operations not included in the sale
to InstruTech Florida, which consist principally of receivables and inventory,
are being liquidated through collections of receivables and through subsequent
sales of inventory to others, including InstruTech Florida.

      We cannot provide any assurance of the amounts that we will be paid under
the promissory note or the bridge loan or that we will recover from inventory
sales or collections of receivables. Thus, a significant portion of the amount
we expect to recover from the discontinuance of our contract manufacturing
operations is dependent upon the success of the operations of the business of
InstruTech Florida, which is outside our control. If the amounts we receive and
recover from these discontinued operations are materially less than we expect,
it will have a material adverse effect on our financial condition, results of
operations and cash flows.

      OUR DEPENDENCE ON THIRD PARTY PARTNERS AND SUPPLIERS, INCLUDING SOLE
      SOURCE SUPPLIERS, MAY PREVENT US FROM DELIVERING ACCEPTABLE PRODUCTS OR
      PERFORMING ACCEPTABLE SERVICES ON A TIMELY BASIS.

      We rely on single source suppliers and highly in demand parts for some of
the critical components we use in our products. Our business is dependent on our
ability to anticipate our needs for components and products and our suppliers'
ability to deliver such components and products in time to meet critical
manufacturing and installation schedules. Our business could be adversely
affected, for example, if PowerSecure is unable to obtain, on a timely and
cost-efficient basis, sufficient generators to meet its customers' installation
schedules. In addition, our business could be adversely affected if we
experience supply constraints or if we experience any other interruption or
delay in the supply chain which interfere with our ability to manufacture our
products or manage our inventory levels.

      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 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.

      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

                                       9



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.

      WE DO NOT HAVE LONG-TERM OR RECURRING COMMITMENTS WITH MOST OF OUR
      CUSTOMERS AND MAY BE UNABLE TO RETAIN EXISTING CUSTOMERS, ATTRACT NEW
      CUSTOMERS OR REPLACE DEPARTING CUSTOMERS WITH NEW CUSTOMERS THAT CAN
      PROVIDE COMPARABLE REVENUES.

      Because we generally do not obtain firm, long-term volume purchase
commitments from our customers, many of our contracts and commitments from our
customers are short-term or non-recurring. 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. In addition,
customer orders can be canceled or rescheduled and volume levels can be reduced.
We cannot assure you that our customers will continue to use our products and
services or that we will be able to replace, in a timely or effective manner,
canceled, delayed or reduced orders with new business that generates comparable
revenues. Further, we cannot assure you that our current customers will continue
to generate consistent amounts of revenues over time. Our failure to maintain
and expand our customer relationships customers would materially and adversely
affect our business and results of operations.

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

      Our future success will depend on our ability to develop 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;

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

                                       10



      -     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 that we have
recently developed or may develop in the future will achieve market acceptance.
If our new products and services fail to achieve market acceptance, or 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 adversely affected.

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

      From time to time, our subsidiaries have derived a material portion of
their revenues from one or more significant customers or purchase commitments.
For example, in fiscal 2003 Metretek Florida had a significant purchase order
from one large customer that did not recur, which adversely affected our
operating results in fiscal 2004. In fiscal 2004, we had one customer that was
responsible for approximately 15% of our consolidated revenues. If such
commitments were to be terminated or fail to recur, our revenues and net income
would significantly decline. Our success will depend on our continued ability to
develop and manage relationships with significant customers and generate
recurring revenues from them. We cannot be sure that we will be able to retain
our largest customers, that we will be able to attract additional large
customers, or that our existing customers will continue to purchase our products
and services in the same amounts as in prior years. Our business and operating
results would be adversely affected by:

      -     the loss of one or more large customers;

      -     any reduction or delay in sales to these customers;

      -     the failure of large purchase commitments to be renewed or to recur;

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

      -     future price concessions that we may have to make to these
            customers.

      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

                                       11



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, any of these new or enhanced products, services and
technology could contain problems that are discovered after they are introduced.
We may need to significantly modify the design of these products and services to
correct problems. Rapidly changing 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
these 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. Although we have
entered into employment agreements with some of our executive officers, we
generally do not have employment contracts with our key employees. In addition,
we do not have key person life insurance for most of our key personnel. 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 in the
future to continue to experience, difficulty in hiring and retaining highly
skilled employees with appropriate qualifications. If we are unable to attract
and retain highly qualified personnel, our business could be materially and
adversely affected.

      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 competing 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 businesses 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, 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 products and

                                       12



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

      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. In recent years, some segments of the economy, including the
technology industry in particular, have experienced significant economic
downturns characterized by decreased product demand, price erosion, work
slowdowns and layoffs. Moreover, there is increasing uncertainty in the energy
and technology markets attributed to many factors, including international
terrorism and strife, 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 adversely affect our ability meet our capital requirement, support our
working capital requirements and growth objectives, maintain our existing
financing arrangements, or otherwise adversely affect our business, financial
condition and results of operations. 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 able to effectively manage our
growth in the future, our business may be materially and adversely affected.

      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 some of our other product and service offerings.
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 MM 1995-2, A PRIVATE PROGRAM, PRESENTS RISKS TO US.

      MGT is our subsidiary that manages and holds a minority ownership interest
in MM 1995-2, a private program that owns and operates four oil and gas
production water disposal facilities. While MGT does not intend to form any new
private programs, it may from time to time increase its economic interest in the
program or initiate or manage actions intended to expand the program's assets or
activities. This program was financed by a private placement of equity interests
raising capital to acquire the assets and business operated by the program. Our
management of this program presents risks to us, including:

      -     lawsuits by investors in this program who become dissatisfied with
            the result of the program;

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

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

      -     changes in the regulatory environment relating to the program;

      -     reliance upon significant suppliers and customers by the program;

                                       13



      -     hazards of oil production water disposal facilities, including
            environmental hazards; and

      -     changes in technology.

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

      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. While sales into international markets generated only approximately 2%
of our consolidated revenues in fiscal 2004 and 3% in fiscal 2003 and fiscal
2002, 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 in 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.

      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 revenues, including:

      -     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;

      -     difficulties in complying with foreign regulatory and commercial
            requirements;

      -     increased costs associated with maintaining international marketing
            efforts;

      -     fluctuations in currency exchange rates;

      -     potential adverse tax consequences;

      -     adverse changes in applicable laws and regulatory requirements;

      -     import and export restrictions;

      -     export controls relating to technology;

      -     tariffs and other trade barriers;

      -     political and economic instability;

      -     reduced protection for intellectual property rights;

      -     cultural and language difficulties;

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

                                       14



      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 to 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. If we are unable to
identify, finance or obtain the benefits of future acquisitions and alliances,
our growth may be impaired and our business may be adversely affected.

      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
            business;

      -     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;

      -     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 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. These financings 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 financings. Available equity or debt financings
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

                                       15



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 in 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 FACE CLAIMS OF INTELLECTUAL PROPERTY INFRINGEMENT BY 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 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 would
divert management 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.

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

                                       16



      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.

      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. For
example, PowerSecure is dependent upon on obtaining a timely and cost-effective
supply of generators for its distributed generation system, and from time to
time these generators are in short supply, affecting the timing and cost of the
generators. We may experience delays in production if the supply of any critical
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, which could materially and adversely affect our business and
operations.

      OUR POWERSECURE BUSINESS IS SUBJECT TO MANY BUSINESS RISKS, AND IF ANY OF
      THEM MATERIALIZE, THEY COULD MATERIALLY AND ADVERSELY AFFECT POWERSECURE'S
      BUSINESS AS WELL AS OUR FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

      PowerSecure's business is dependent, in part, upon its ability to utilize
distributed generation to create favorable pricing for customers based on
existing tariff structures. If utility tariffs change in some regions, then
PowerSecure's business would become less viable in those regions. Moreover, even
if such tariffs do not change, if PowerSecure is unable to obtain the expected
benefits from those tariffs, its shared savings projects, that are dependent
upon such benefits, would be materially and adversely affected. Also,
PowerSecure presently utilizes diesel powered generators in its systems. If
regulatory requirements in certain regions are modified to make diesel no long
viable in those regions, PowerSecure's business could be adversely affected.
While PowerSecure, in such case, would utilize its efforts to find alternative
power sources, there is no assurance those alternative sources would be
economically acceptable.

      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

                                       17



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.

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

      The terrorist attacks on September 11, 2001 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 throughout the
world, the escalation of military action, and heightened security measures in
response to such threats may cause significant disruption to commerce throughout
the world. To the extent that such disruptions result in reductions in capital
expenditures or spending on technology, longer sales cycles, deferral or delay
of customer orders, or an inability to effectively market our products or
services, our business and results of operations could be materially and
adversely affected.

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

      Recently enacted changes in the laws and regulations affecting public
companies, especially those pertaining to corporate governance and public
disclosure such as the Sarbanes-Oxley Act of 2002 and related SEC regulations,
have caused us to incur increased costs of compliance and have resulted 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 may increase our costs and
thus adversely affect our reported financial results, which could have an
adverse effect on our stock price.

      For example, in December 2004, the Financial Accounting Standards Board
issued Financial Accounting Standard No. 123(R), which will become effective in
our third quarter of fiscal 2005. FAS 123(R) will result in our recognition of
compensation expense relating to our employee stock options. Currently, as
permitted under FAS 123, we generally do not recognize any compensation related
to stock option grants we issue under our stock option plans. Under FAS 123(R),
we are required to adopt a fair value-based method for measuring the
compensation expense related to employee stock awards that will lead to
additional compensation expense.

      These and other new rules or laws 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.

      THERE IS NO ASSURANCE THAT WE WILL BE ABLE TO IMPLEMENT, IN A TIMELY
      MANNER, THE INTERNAL CONTROLS PROCEDURES NECESSARY TO ALLOW OUR MANAGEMENT
      TO REPORT ON THE EFFECTIVENESS OF OUR INTERNAL CONTROLS.

      Under Section 404 of the Sarbanes-Oxley Act of 2002, we will be required
to furnish an internal controls report of management's assessment of the
effectiveness of our internal controls as part of our Annual Report on Form 10-K
for the fiscal year ended December 31, 2006. Our independent registered public
accounting firm will then be required to attest to, and report on, our
assessment. In order to issue our report, our management must document both the
design of our internal controls and the testing processes that support
management's evaluation and conclusion. Our management has begun the necessary
processes and procedures for issuing its report on our internal controls.
However, there can be no assurance that we will be able to complete the work
necessary for our management to issue its management report in a timely manner,
or that management will be able to report that our internal control over
financial reporting is effective.

                         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.

      As of April 1, 2005, our executive officers, directors and 5% or greater
stockholders beneficially owned, in the aggregate, approximately 43.5% of our
outstanding common stock, assuming they exercise or convert all stock options
and warrants that are exercisable or convertible within 60 days of that date. 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 and the approval of mergers,
sales of substantially all of our assets and other significant corporate
transactions. The interests of these stockholders may differ from 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 affecting 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 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.

      As of April 1, 2005, 12,258,782 shares of common stock were outstanding.
On that date, options to

                                       18


purchase 2,013,311 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, warrants
to purchase 2,374,272 shares of common stock were outstanding. The resale of all
shares underlying these options and warrants are covered by currently effective
registration statements. 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 the common stock to decline.


      OUR CHARTER DOCUMENTS AND OUR STOCKHOLDER RIGHTS PLAN, AS WELL AS DELAWARE
      LAW, CONTAIN ANTI-TAKEOVER PROVISIONS THAT COULD DISCOURAGE OR PREVENT A
      THIRD-PARTY ACQUISITION OF OUR COMMON STOCK, EVEN IF AN ACQUISITION WOULD
      BE BENEFICIAL TO OUR STOCKHOLDERS.

      Some provisions in our second restated certificate of incorporation, our
amended and restated by-laws, and our stockholder rights plan, 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 doing so would
be beneficial to stockholders. These provisions could also limit the price that
investors might be willing to pay in the future for shares of our common stock.
These provisions include:


                                       19


      -     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
            our common stock and our preferred stock;

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

      -     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;

      -     the dilutive effects of our stockholders rights plan to a potential
            acquirer;

      -     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.

      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. 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 CHANGE OUR INTENTIONS 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.

                                       20


      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 by prohibiting the payment of dividends by our subsidiaries without
the consent of the lender. 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;

      -     introduction of new 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 significant technical
            innovations, products, services, 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;

      -     general economic, business and market conditions; and

      -     sales of our common stock by our 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 SHARES OF PREFERRED STOCK THAT COULD DILUTE THE INTERESTS OF
      HOLDERS OF OUR COMMON STOCK.

      Our charter currently authorizes our board of directors to issue up to
2,000,000 shares of preferred stock on terms to be fixed by the Board of
Directors. The terms of our common stock do not limit the issuance of shares of
preferred stock. The issuance of shares of preferred stock could dilute the
interests 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

                                       21


      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.

                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

            cash equivalents, funds generated from operations, available
            borrowings under our credit arrangements and other capital

limited to, those

                                       22


described in "Risk Factors," or as well as other risks, uncertainties and
factors discussed elsewhere in this prospectus, in documents that we include as
exhibits to or incorporate by reference in this prospectus, and in other reports
and documents we from time to time file with or furnish to the Securities and
Exchange Commission.

      Any forward-looking statements contained in this prospectus speak only as
of the date of this prospectus. We do not intend, and we undertake no duty or
obligation, to update or revise any forward-looking statement for any reason,
whether as a result of changes in our expectations or the underlying
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 of the 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 will be for the account of
the selling securityholders listed below in "Selling Securityholders."

      However, because 2,374,272 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 $7.6 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 our May 2004 private placement, we agreed in a registration rights
agreement to register the 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.

This prospectus covers the resale of 2,206,131 shares of common stock, and
1,045,164 shares of common stock issuable upon the exercise of Series A warrants
and Series B warrants, issued to certain of the selling securityholders in our
May 2004 private placement.

      We also agreed to register the resale or other distribution of 1,329,173
shares of common stock, and 1,329,173 shares of common stock issuable upon the
exercise of Series C warrants, issued to certain selling securityholders who
converted shares of Series B preferred stock into shares of common stock in
2004.

                                       23


      In addition, we agreed to register the resale or other distribution of
shares of common stock, and of shares of common stock issuable upon the exercise
of warrants, issued to certain securityholders in our December 1999 and February
2000 private placements under a registration rights agreement. Under that
registration rights agreement, we agreed to maintain the effectiveness of a
registration statement until three months after the selling securityholders
ceased to be affiliates. This prospectus covers 600,000 shares of common stock
issued in or in connection with those private placements, as well as the resale
or other distribution of 1,209,133 shares of common stock, and 1,209,133 shares
of common stock issuable upon the exercise of Series C warrants, issued to
certain selling securityholders who converted shares of Series B preferred stock
into shares of common stock in 2004.

      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 April 1, 2005, except as otherwise
stated in the notes to the table, the following information based on 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 offered, sold or otherwise
disposed of 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 April 1,
2005. 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 12,258,782 shares of common stock outstanding
on April 1, 2005.

      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 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

                                       31


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
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

                                       32


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 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. As of April 1, 2005,
12,258,782 shares of our common stock and no shares of our preferred stock were
issued and outstanding

      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, and to 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. Subject to 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 therefor. Upon our
liquidation, dissolution or winding up, the holders of our common stock are
entitled to share ratably in all assets remaining after the payment of all debts
and other liabilities, subject to 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 the holders of our common stock depend upon,
and could be adversely affected by, the rights of the holders of any shares of
preferred stock that we 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, 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

                                       33


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. During 2000 and 2001, in connection with a
series of private placements of securities, we issued 6,000 shares of Series B
preferred stock. On December 9, 2004, in accordance with its terms, all shares
of Series B preferred stock the outstanding were redeemed for a purchase price
equal to their liquidation preference plus accrued and unpaid dividends.

      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.

OPTIONS

      As of April 1, 2005, options to purchase 2,013,311 shares of our common
stock with exercise prices ranging from $0.46 to $17.38 per share were
outstanding under our three stock options plans:

      -     our 1991 Stock Option Plan;

      -     our Directors' Stock Option Plan; and

      -     our 1998 Stock Incentive Plan.

WARRANTS

      As of April 1, 2005, warrants to purchase 2,374,272 shares of our common
stock with exercise prices ranging from $3.0571 to $3.41 were outstanding.

      In the May 2004 private placement, we issued Series A warrants to
investors and Series B warrants to the placement agent. As of April 1, 2005,
Series A warrants to purchase 694,044 shares of common stock were outstanding
and Series B warrants to purchase 351,055 shares of common stock were
outstanding. Each Series A and Series B warrant is exercisable at an exercise
price of $3.41 per share until May 2009. The Series A 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 Series B warrants issued to the placement agent may be
exercised on a cashless basis at any time.

      In May and July 2004, we issued Series C warrants to certain holders of
our Series B preferred stock that converted some of their shares of our Series B
preferred stock into shares of our common stock. As of April 1, 2005, Series C
warrants to purchase 1,329,173 shares of common stock were outstanding. The
Series C warrants are exercisable at an exercise price of $3.0571 per share
until June 9, 2005. The Series C warrants 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.

      The exercise price of all outstanding warrants is subject to adjustment to
prevent dilution. This prospectus covers the resale of all shares of common
stock that may be acquired by the selling securityholders upon the exercise of
these warrants.

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 persons 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 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 STOCKHOLDERS TO ACT BY WRITTEN CONSENT OR TO CALL
SPECIAL MEETINGS. Our second restated certificate eliminates the ability of
stockholders to act by written consent. In addition, our by-laws provide that
special meetings of our stockholders may be called only by our President or by
our board of directors. These provisions combined make it difficult for a
stockholder to take action on a timely basis without the consent of 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

                                       35


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 to 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;

      -     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

                                       36


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 our rights agreement is $15.00. The rights trade
automatically with the shares of our common stock and become exercisable only
under the circumstances described below. Until a right is exercised, the holder
thereof will have no rights as a stockholder of our company.

      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 our 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.

      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 an acquiring person. 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 our rights
agreement. After the distribution date, our 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

                                       37


      -     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, our 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.

      Because our rights agreement is designed to protect us against coercive
takeover tactics, it contains provisions that may 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, our
rights agreement is not intended to prevent a takeover, but rather is designed
and intended to encourage potential acquirers to negotiate with our board of
directors prior to attempting a takeover and to provide our board of directors
with leverage in negotiating, on behalf of all stockholders, the terms of any
proposed takeover. Our rights agreement should not interfere with any merger or
business combination approved by our board of directors.

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.

                                       38


      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.

      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.

                                  LEGAL MATTERS

      Kegler, Brown, Hill & Ritter Co., L.P.A., Columbus, Ohio, will pass upon
the validity of the common stock that may be offered under this prospectus.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

      The Registrant is a Delaware corporation. 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, the Registrant's Second Restated Certificate of Incorporation ("Second
Restated Certificate") permits the Registrant 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 the Registrant, by reason of the fact
such person is or was an officer of director of the Registrant, or is or was
serving at the Registrant'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 the Registrant, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe such person's conduct was
unlawful. The Registrant 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 the Registrant 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 the
Registrant 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. The
Registrant 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 Registrant's Second Restated Certificate, By-Laws, or under any
agreement, vote of stockholders or disinterested directors or otherwise. No
repeal or modification of these provisions of the Registrant's 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 such repeal or modification.

      The Registrant's Amended and Restated By-Laws provide that the Registrant
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, the Registrant's Second
Restated Certificate also eliminates the personal liability of the Registrant'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 

                                      II-1


or our stockholders; (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing 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.

      The Registrant's Second Restated Certificate also specifically authorizes
the Registrant to maintain insurance and to grant similar indemnification rights
to employees or agents of the Registrant. The directors and officers of the
Registrant 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.

      The Registrant has also entered into indemnification agreements with each
of its directors that require the Registrant 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)  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
            registration statement is on Form S-3, Form S-8 or From F-3, and 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 

                                      II-7


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.

(d) The undersigned Registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered, to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prosecutes to provide such interim financial information.

                                      II-8



                                   SIGNATURES

requirements for filing on Form S-2 and has duly caused this Post-Effective
