and projections are expressed in good faith and are believed by the Company to

of historical operating trends, data contained in the Company's records and
other data available from third parties, but there can be no assurance that
management's expectations, beliefs or projections will result or be achieved or
accomplished. In addition to other factors and matters discussed elsewhere
herein, the following are important factors that, in the view of
                                        2
<PAGE>   5
 
the Company, could cause actual results to differ materially from those
discussed in the forward-looking statements: the ability of the Company to
attain widespread market acceptance of its technology; the ability of the
Company to obtain acceptable forms and amounts of financing to fund planned
expansion efforts; demand for the Company's services; competitive factors; the
actual useful life of ITD Units; and the ability of the Company to maintain
acceptable utilization rates on its equipment.
 
                                  THE COMPANY
 
     The Company was incorporated under the laws of the State of Nevada in
December 1985, under the name of Cape Cod Investment Company. In December 1986,
the name of the Company was changed to Cape Cod Ventures, Inc. In August 1987,
the Company completed an initial public offering of 4,148,000 shares of Common
Stock at a price of $0.001 per share pursuant to the exemption from the
registration requirements of the Securities Act of 1933 provided by Regulation
A. In May 1993, the Company executed an Agreement and Plan of Reorganization
(the "Reorganization Agreement") with National Fuel & Energy, Inc. ("NFE"),
providing for the acquisition of NFE by the Company in exchange for shares of
the Company's Common Stock. In connection with the reorganization, the name of
the Company was changed to Environmental Safeguards, Inc., and NFE became a
wholly-owned subsidiary of the Company. NFE is a Wyoming Corporation. In
December 1997, the Company, through NFE, acquired the remaining 50% interest in
OnSite Technology, L.L.C., an Oklahoma limited liability company, ("OnSite")
which was previously owned by Parker Drilling Company. As a result of this
transaction OnSite is now a wholly owned subsidiary of NFE.
 
     Substantially all of the Company's activities are conducted through OnSite
which is engaged in the development, production and sale of environmental
remediation and recycling technologies and services. OnSite owns the
technologies included in the Company's indirect thermal desorption units ("ITD
Units"), and the proprietary processes for on-site remediation and recycling of
hydrocarbon contaminated soil. To date, the environmental remediation and
recycling services provided by the Company have involved the removal of
petroleum contaminants from soil using the ITD Units. Each ITD Unit is an easily
transportable processing system which produces clean soil from contaminated soil
while reclaiming the hydrocarbons. ITD Units are transported from one clean-up
site to another. To date, the environmental remediation and recycling services
provided by the Company have involved the removal of petroleum contaminants from
soil using indirect thermal remediation and recycling equipment. The Company's
customers have been large corporations in the oil and gas drilling industry that
have anticipated the changing regulatory climate with respect to soil and other
environmental contamination and have taken the initiative in removing
contaminants from their properties.
 
     The primary services offered by the Company involve remediation and
recycling of soil contaminated by oil-based drilling mud, fuel spills, leakage
at storage tanks and other sources of hydrocarbon contamination. To remediate
and recycle the contaminated soil, the Company utilizes ITD Units consisting of
(i) an indirect thermal desorption unit wherein the hydrocarbon contaminated
soil is indirectly heated, thereby causing the hydrocarbon contamination to
vaporize; and (ii) a condensation process system, which causes the hydrocarbon
vapor to condense to a liquid, or an afterburner or thermal oxidizer which
incinerates the hydrocarbon vapor. The ITD Units are mobile, and thus,
contaminated soil can be remediated and recycled at the customer's location. The
Company, through OnSite, typically submits a bid for a project based on the
costs of moving the equipment to the location, the estimated charges for labor
and fuel, the nature and extent of the contamination, the type and moisture
content of the soil, the estimated processing time and the desired profit
margin. Generally, once a contract has been awarded, OnSite moves its equipment
to the customer's location. The Company does not haul or dispose of soil or
contaminants away from the customer's location.
 
     OnSite currently operates three of the four ITD Units which it owns. Of
these, one ITD Unit is operating for Newpark Resources, Inc. ("Newpark
Resources") in Louisiana, one ITD Unit is in Venezuela pending the finalization
of a contract with a major oil and gas industry participant, and the third ITD
Unit is newly fabricated and undergoing internal quality control review. The
fourth ITD Unit which the Company owns is leased to OnSite Columbia, Inc.
("Onsite Colombia") in which OnSite owns a 50% interest. OnSite
 
                                        3
<PAGE>   6
 
Colombia leases one ITD Unit from OnSite as stated above, and OnSite Colombia
leases two additional ITD Units pursuant to sale-leaseback agreements with
unrelated third parties. OnSite Colombia operates all of the ITD Units in
Colombia for a major oil and gas industry participant. Four additional ITD Units
are under construction and are anticipated to be ready for use at customer
locations starting in May, 1998, bringing the Company's portable fleet to 10.
However, there is no assurance that completion or delivery of these four
additional ITD Units will take place as scheduled.
 
     Unless otherwise indicated, references to the Company include OnSite and
NFE, the Company's wholly owned subsidiaries.
 
     The offices of the Company are located at 2600 South Loop West, Suite 645,
Houston, Texas 77054 and its telephone number is (713) 641-3838.
 
     The Company's Common Stock is traded on the American Stock Exchange under
the symbol "EVV".
 
                                  RISK FACTORS
 
     The Common Stock offered hereby is speculative and involves a high degree
of risk. In addition to the other information set forth in this Prospectus, each
prospective investor should carefully consider the following risk factors before
making an investment decision.
 
RECENT LOSSES
 
     The Company incurred net losses of $1,849,000 and $647,000 for the fiscal
years ended December 31, 1997 and December 31, 1996, respectively. In order to
attain profitability, the Company must secure contracts at acceptable processing
prices and control costs so as to produce a positive operating margin. There can
be no assurance the Company can do so, and the failure of the Company to obtain
profitability could ultimately result in the inability of the Company to pay its
financial obligations as they become due.
 
     At December 31, 1997, and 1996, the Company reported working capital of
approximately $5,277,000 and $3,304,000 respectively. The Company has
historically funded its operations through a combination of internally generated
cash, short-term borrowing and through debt and equity financing. Until such
time as the operating results of the Company improve sufficiently to fund the
Company's operations, the Company must obtain outside financing to fund the
expansion of its business. Any additional debt or equity financing may have a
dilutive effect.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company has experienced prior losses from operations. This circumstance
and the significant commitment by the Company to expand its ITD Unit fleet may
cause the Company liquidity problems. In December, 1997, the Company raised from
an investor group $14,000,000 in a debt and equity financing, of which
$8,000,000 consisted of $4,000,000 of Series B Convertible Preferred Stock and
$4,000,000 of Series C Preferred Stock and $6,000,000 consisted of debt (the
"Debt") as evidenced by several term notes issued pursuant to a Loan and
Security Agreement with the investor group (the "Loan Agreement"). Pursuant to
the terms of the Loan Agreement, the Company has the right to borrow an
additional $5,000,000 provided that it is not in default under the terms of the
Loan Agreement. The Company used a portion of the proceeds of that transaction
to acquire the remaining 50% interest in OnSite and to retire $3,000,000 in
existing debt. As a result of these transactions, the Company retained
approximately $3,000,000 to utilize for working capital, expenses associated
with the financing and general corporate purposes. See, "Recent Events".
 
ONGOING CAPITAL REQUIREMENTS OF ONSITE
 
     The Company's ability to expand and increase its revenues, assets and
income is directly related to its ability to pay for construction of new ITD
Units as demand dictates. Further capital could be needed to meet such demand
and would be required to be provided from the Company's operations, from the
sale of equity securities, borrowing, or other sources of third party financing.
There is no assurance that capital will be
 
                                        4

available from any of these sources. Further, the sale of equity securities
could dilute the Company's existing stockholders' interest, and borrowings from
third parties could result in restrictive loan terms which would increase its
debt service requirements and could restrict the Company's operations. Pursuant
to the terms of the Loan Agreement, the Company has available an additional
credit facility in the amount of $5,000,000 (the "Credit Facility") provided
that the Company is not in default under the Loan Agreement.
 
FOREIGN POLITICAL CLIMATE
 
     The Company, through OnSite Colombia, has entered into contracts with major
global oil and gas industry participants for the Company's remediation and
recycling services. Three ITD Units are operating in the Republic of Colombia.
Any changes in the political climate of the Republic of Colombia, or even a mere
unsettling in the current political climate, could have a negative impact on the
Company, up to and including the complete loss of ITD Units operating in the
Republic of Colombia. The Republic of Colombia has had an unsettling past
involving drug trafficking, narco-terrorism, domestic terrorism, and alleged
political corruption. While the Company maintains hazard insurance to address
these risks in the Republic of Colombia, the loss of potential income due to the
interruption of the Company's services could have an adverse effect on the
financial condition of the Company. See, Risk Factors -- Operating Risks and
Possible Insufficiency of Insurance. Further, the Company's assets and
operations located in Colombia are subject to the risk of nationalization or
expropriation. The Company has not experienced any set backs in connection with
the foreign political climate. The Company anticipates that the scope of its
operations may include activity in other nations where similar risks could
exist.
 
INTERNATIONAL TRANSACTIONS
 
     The Company is taking part in business operations in the Republic of
Colombia as described elsewhere herein. International business transactions
might create exposure for the Company to potential financial concerns in the
areas of foreign currency exchange, if the Company is paid in whole or in part
in a foreign currency, routine or extraordinary foreign government control of
the transfer of funds across international borders, and foreign taxes, tariffs
and duties. Any of the foregoing could adversely impact the Company. The Company
anticipates that the scope of its operations may include other nations in South
America, such as the Republic of Venezuela, where similar risks exist. The
functional currency of OnSite Colombia is the U.S. dollar because customer
invoicing, customer receivables, imported equipment and many of the operating
cost factors are denominated in U.S. dollars. The Company plans to continue to
implement the same approach as other foreign operations come on stream in the
course of conducting business abroad in an effort to minimize risks associated
with foreign exchange fluctuation and its affect on Company profitability.
 
FABRICATION OF ITD UNITS
 
     The Company uses outside fabricators to construct the ITD Units. The
Company negotiates bids and awards contracts for fabrication. The Company has
proprietary designs and engineering techniques which it uses for custom
fabrication. The fabrication process may subject the Company to several risks.
Deficient fabrication or financial instability of a fabricator could upset the
Company's ability to manufacture the ITD Units on a timely basis which could
result in delays in fulfilling contracts for soil remediation and recycling.
Failure to fulfill contracts for remediation and recycling could result in the
loss of such contracts or could subject the Company to liability for
nonperformance of the contracts. The Company has identified at least five
fabricators currently capable of fabricating the ITD Units at a competitive
price. Four additional ITD Units which are presently being fabricated for the
Company are expected to be ready for shipment to customer locations starting in
May, 1998, bringing the Company's portable fleet to 10. However, there is no
assurance that completion or delivery of these four additional ITD Units will
take place as scheduled.
 
ECONOMIC CONDITIONS AND RELATED UNCERTAINTIES
 
     Environmental service companies are affected by economic conditions as well
as government policies. Economic downturns could result in decreased demand for
the Company's services. Potential customers could seek to delay their
environmental remediation and recycling programs during such economic downturns.
The
                                        5
<PAGE>   8
 
Company's operations are dependent upon its ability to market its services.
While the Company would aggressively pursue its marketing efforts, in a time of
general or industry specific decline, such as a decline in oil and gas drilling
activity or a decline in the demand for remediation and recycling services, the
Company's business activities could be adversely affected.
 
PRODUCT DEVELOPMENT RISKS, AND USEFUL LIFE OF ITD UNITS
 
     The ITD Units used by the Company are continually being refined, adjusted
and improved. There is no assurance that the Company's ITD Units will perform in
accordance with the Company's expectations over a long period of time or that
there will be continued demand for the Company's products and services in
commercially justifiable quantities. The Company estimates that the useful life
of an ITD Unit is 5 years. However, the actual useful life of an ITD Unit is
unknown and could be greater or less than 5 years.
 
PROPRIETARY TECHNOLOGY
 
     The U.S. Patent and Trademark Office has allowed certain claims to methods
and apparatuses for removing and treating hydrocarbon contaminated drill
cuttings and a patent has been issued to the Company. Other inventions of the
Company are patent-pending. The Company has also filed for patent protection
through the Patent Cooperation Treaty, and directly in certain foreign
countries. The Company has also filed additional U.S. patent applications for
treating hydrocarbon contaminated soil; for the process and apparatus of
separating and recovering hydrocarbons and water from the ITD Units; and on
several novel ITD Unit mechanical features. The Company cannot state that others
will not independently develop alternative proprietary information for similar
types of processes and apparatus. The Company has not received notice that any
of its apparatus or processes used in regard to the ITD Units infringe upon any
U.S. patent.
 
GOVERNMENTAL REGULATIONS
 
     The Company renders services in connection with the remediation, recycling
and disposal of various wastes. Federal, state and local laws and regulations
have been enacted regulating the handling and disposal of wastes and creating
liability for certain environmental contamination caused by such waste.
Accordingly, the Company is subject to potential liability for environmental
damage its ITD Units or its operations may cause, particularly as a result of
contamination of water or soil. Environmental laws regulate, among other things,
the transportation, storage, handling and disposal of waste. Moreover, so-called
"toxic tort" litigation has increased markedly in recent years as persons
allegedly injured by chemical contamination seek recovery for personal injuries
or property damage. These legal developments present a risk of liability should
the Company be deemed to be responsible for contamination or pollution caused or
increased by any remediation, recycling or cleanup effort conducted by it, or
for an accident which occurs in the course of such remediation, recycling or
cleanup effort. There can be no assurance that the Company's policy of
establishing and implementing proper procedures for complying with environmental
regulations will be effective at preventing the Company from incurring a
substantial environmental liability. If the Company were to incur a substantial
uninsured liability for environmental damage, its financial condition could be
materially adversely affected. Furthermore, the Company may from time to time
become subject to governmental enforcement proceedings and resulting fines or
other sanctions and may incur penalties. Such expenditures could be substantial
and accordingly could have a material adverse effect on the Company's financial
condition.
 
     The Company presently has the ability to perform soil remediation and
recycling services that meet applicable federal and state standards for the
delivery of its services, and for the level of contaminant removal. The
government can, however, impose new standards. If new regulations were to be
imposed, the Company may not be able to comply in either the delivery of its
services, or in the level of contaminant removed from the soil.
 
COSTS OF COMPLIANCE WITH GOVERNMENTAL REGULATIONS
 
     Governmental regulations govern matters such as the disposal of residual
chemical wastes, operating procedures, waste water discharges, fire protection,
worker and community right-to-know, and emergency
 
                                        6
<PAGE>   9
 
response plans. Governmental authorities have the power, under various
circumstances, to enforce compliance, and violators may be subject to civil or
criminal penalties. Private individuals may also have the right to sue to
enforce compliance with certain of the governmental requirements.
 
     Operating permits are generally required by federal and state environmental
agencies for the operation of the Company's ITD Units. Most of these permits
must be renewed periodically and the governmental authorities involved have the
power, under various circumstances, to revoke, modify, or deny issuance or
renewal of these permits. However, it is generally the Company's customers who
must obtain such permits, if applicable, not the Company.
 
     As a result of the stringent regulations governing the operation of the
Company's ITD Units, operating the ITD Units and conducting business in
compliance with the various applicable regulations requires the Company to
commit significant human and capital resources and results in increased
operating costs. The Company may from time to time become subject to
governmental enforcement proceedings and resulting fines or other sanctions and
may incur penalties. Such expenditures can be substantial and accordingly could
have a material adverse effect on the Company's financial condition.
 
COMPETITION
 
     There are many companies which currently dispose of hazardous and
industrial wastes and remediate, recycle or clean up sites which have been
contaminated, and such companies are continually attempting to develop new and
improved products and services. Other companies utilize competing technologies
and techniques in an attempt to provide more economical or superior remediation
and recycling services. Many of the Company's competitors are well established
companies with substantially greater capital resources, larger research and
development staffs and facilities and substantially greater marketing
capabilities than the Company. No assurances can be given that the Company will
be able to successfully compete with such companies or alternative technologies.
 
TECHNOLOGICAL OBSOLESCENCE
 
     The Company uses a method called indirect thermal desorption to remediate
and recycle soil. While the Company believes that this technology has a long
market life, there is no assurance that the Company's technology will be
marketable in the future. Existing or future technologies of competitors could
make the Company's services obsolete and the Company could suffer a loss of
customers and revenue as a result. The Company's research and development
activities, to the extent that such activity takes place, are de minimis and
relate only to the incidental efforts of the Company to make incremental
improvements in operating efficiencies, design, and fabrication.
 
OPERATING RISKS AND POSSIBLE INSUFFICIENCY OF INSURANCE
 
     The business of the Company exposes it to various risks, including claims
for damage to property, injuries to persons, negligence and professional errors
or omissions in the planning or performing of services, which claims could be
substantial. OnSite, the entity through which operations are conducted,
maintains $1,000,000 of general liability insurance, $1,000,000 of auto
liability insurance and an additional $5,000,000 of excess umbrella liability
coverage on all of its operations. There can be no assurances that such
insurance will continue to be adequate to meet the needs of the Company, or that
the Company will be able to continue to maintain or obtain adequate or required
insurance coverage as its business grows or, if obtainable, purchase it at
reasonable rates. If the Company has difficulty in maintaining or obtaining such
coverage, it could be at a competitive disadvantage with other companies, it may
become exposed to significant uninsured risks and losses, and/or may be unable
to continue certain of its operations. Under the Company's insurance policies,
there are various exclusions that are customary in the industry. Accordingly,
there can be no assurance that liabilities that may be incurred by the Company
will be covered by its insurance or that the dollar amount of such liabilities
which are covered by its insurance will not exceed the Company's policy limits.
A partially or completely uninsured claim, if successful, could have a material
adverse effect on the Company's financial condition and results of operations.

LACK OF DIVERSIFICATION; RISKS OF INVESTING IN THE INDUSTRY
 
     The Company operates primarily in the environmental services industry. The
current plan of operation calls for expansion within, but does not anticipate
diversification beyond, this industry. The plan of operation, therefore,
subjects the Company to the economic fluctuations within this industry and
increases the risk associated with its operations. An investment in any aspect
of the environmental services industry is speculative and historically has
involved a high degree of risk. The continued success of the Company will depend
on various factors over which the Company has little or no control.
 
DEPENDENCE ON MANAGEMENT
 
     The Company is dependent upon the time, talent and experience of James S.
Percell, its President and Chief Executive Officer, with whom the Company has an
employment agreement. The loss of the services of Mr. Percell, for any reason,
could have a material adverse effect on the Company. The Company, however, has
obtained key-man life insurance on Mr. Percell in the amount of $5,000,000.
 
FUTURE NEED FOR ADDITIONAL PERSONNEL
 
     As a result of a recent restructuring of the management and operations of
the Company, the Company has obtained the services of new personnel to perform
certain functions important to the long-term development of the Company,
including operations, accounting, finance and quality control functions. The
Company may hire additional staff with the special skills and education
necessary for important Company functions. Competition for such personnel is
intense, and there can be no assurance that the Company will be successful in
attracting and retaining such personnel.
 
ANTI-TAKEOVER EFFECTS OF ISSUANCE OF PREFERRED STOCK
 
     The Company has authorized 10,000,000 shares of preferred stock, par value
$0.001 per share ("Preferred Stock"), of which the Company has issued and
outstanding 3,771,422 shares of Series B Convertible Preferred Stock and 400,000
shares of Series C Preferred Stock. Thus, the Company could issue up to
5,828,578 additional shares of Preferred Stock. Preferred Stock is entitled to
certain preferences over the Common Stock. The Company's board of directors has
authority, without action or consent by the shareholders, to issue the
authorized but unissued shares of Preferred Stock in one or more series and to
determine the voting rights, preferences as to dividends and liquidation rights,
conversion rights, and other rights of any such series. All Preferred Stock,
when and if issued, could adversely affect the rights of the holders of Common
Stock. For example, such issuances could result in a class of securities
outstanding that would have preferences with respect to voting rights and
dividends and in liquidation over the Common Stock, and could, upon conversion
or otherwise, enjoy all of the rights of holders of Common Stock. The Board's
authority to issue Preferred Stock could discourage potential takeover attempts
and could delay or prevent a change in control of the Company through merger,
tender offer, proxy contest or otherwise by making such attempts more difficult
to achieve or more costly. Further, pursuant to the Loan Agreement, the Company
may not merge or consolidate with any Person, or sell, lease, transfer or
otherwise dispose of any substantial part of its assets (whether in one or more
transactions).
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     There is currently only a limited market for the common stock of the
Company. Possible or actual sales of a substantial number of shares of Common
Stock by the Selling Stockholders in this Offering could have a negative impact
on the market price of the Common Stock of the Company. Further, the Company
does not anticipate engaging an Underwriter to assist in a distribution of
shares of Common Stock on behalf of the Selling Stockholders.
 
     Accordingly, there is no assurance that the Selling Stockholders will be
able to sell the shares of Common Stock for any particular price.
 
                                        8
<PAGE>   11
 
     In addition, of the 9,282,265 shares of the Company's Common Stock
outstanding as of January 28, 1998, approximately 3,975,958 shares are
restricted securities as that term is defined in Rule 144 adopted under the Act
("Restricted Securities"). Rule 144 governs resales of Restricted Securities for
the account of any person, other than an issuer, and restricted and unrestricted
securities for the account of an "affiliate" of the issuer. Restricted
securities generally include any securities acquired directly or indirectly from
an issuer or its affiliates which were not issued or sold in connection with a
public offering registered under the Securities Act. An affiliate of the issuer
is any person who directly or indirectly controls, is controlled by, or is under
common control with, the issuer. Affiliates of the Company may include its
directors, executive officers, and persons directly or indirectly owning 10% or
more of the outstanding Common Stock. Under Rule 144 unregistered resales of
restricted Common Stock cannot be made until it has been held for one year from
the later of its acquisition from the Company or an affiliate of the Company.
Thereafter, shares of Common Stock may be resold without registration subject to
Rule 144's volume limitation, aggregation, broker transaction, notice filing
requirements, and requirements concerning publicly available information about
the Company ("Applicable Requirements"). Resales by the Company's affiliates of
restricted and unrestricted Common Stock are also subject to the Applicable
Requirements. The volume limitations provide that a person, or persons who must
aggregate their sales, cannot, within any three-month period, sell more than the
greater of (i) one percent of the then outstanding shares, or (ii) the average
weekly reported trading volume during the four calendar weeks preceding each
such sale. A person who is not deemed an "affiliate" of the Company and who has
beneficially owned shares for at least two years would be entitled to sell such
shares under Rule 144 without regard to the Applicable Requirements. The Company
believes that approximately 1,176,595 shares of Common Stock have been held for
more than two years, and therefore may be sold by nonaffiliates without
limitation.
 
     No prediction can be made as to the effect, if any, that sales of shares of
Common Stock or the availability of such shares for sale will have on the market
prices prevailing from time to time. Nevertheless, the possibility that
substantial amounts of Common Stock may be sold in the public market would
likely have a material adverse effect on prevailing market prices for the Common
Stock and could impair the Company's ability to raise capital through equity
financing.
 
DILUTION DUE TO OUTSTANDING OPTIONS AND WARRANTS
 
     In addition to the 3,771,422 shares of Common Stock issuable upon
conversion of the Series B Convertible Preferred Stock and the 707,142 shares of
Common Stock issuable upon the exercise of the Warrants, the Company presently
has outstanding options to purchase (i) 2,760,000 shares of its Common Stock
which are exercisable at $0.60 per share and expire in November 2005, (ii)
602,500 shares of its Common Stock which are exercisable at $2.50 per share and
expire in March 2007, (iii) 25,000 shares of its Common Stock which are
exercisable at $3.75 per share and expire in November 2007, (iv) 1,110,114
shares its Common Stock which are exercisable at $3.00 per share and expire in
December 2007, (v) 463,542 shares of its Common Stock which are exercisable at
$5.00 per share and expire in November 1998, and (vi) 3,248 shares of its Common
Stock which are exercisable in approximately equal amounts at prices ranging
from $2.38 to $4.00 per share and expire in January 2008. The exercise of the
outstanding options by the holders thereof may result in the dilution in the
interests of the other stockholders of the Company.
 
     Further, pursuant to the Loan Agreement, the Company is required to issue
additional warrants if certain conditions exist in the future. If the Debt is
not repaid in full by February 17, 2001, then the Company must authorize, issue
and deliver warrants to acquire up to 188,571 shares of common stock. If the
Company borrows additional funds pursuant to the Credit Facility, then the
Company must authorize, issue and deliver warrants to acquire up to 707,142
shares of common stock.
 
POSSIBLE VOLATILITY OF COMMON STOCK PRICE
 
     The market price of the Common Stock of the Company may be highly volatile,
as has been the case with the securities of many other small capitalization
companies. Additionally, in recent years, the securities markets have
experienced a high level of price and volume volatility and the market prices of
securities for many companies, particularly small capitalization companies, have
experienced wide fluctuations which have
                                        9
<PAGE>   12
 
not necessarily been related to the operating performances or underlying asset
values of such companies. Securities of issuers having relatively limited
capitalization or securities recently issued in a public offering are
particularly susceptible to change based on short-term trading strategies of
certain investors. Further, the resale of Common Stock in this Offering by
Selling Stockholders could affect the market price of the Common Stock.
 
NO CASH DIVIDENDS
 
     The Company has never paid cash dividends on its Common Stock and the Board
of Directors does not anticipate paying cash dividends in the foreseeable
future. It currently intends to retain future earnings to finance the growth of
its business. Further, pursuant to the terms of its Loan Agreement with Cahill,
Warnock Strategic Partners Fund, L.P. and others, the Company is precluded from
paying any dividends while the loan is outstanding. See, "Recent Events".
 
                                 RECENT EVENTS
 
     On December 17, 1997, Environmental Safeguards, Inc. (the "Company"),
entered into a Purchase Agreement (the "Purchase Agreement") with Parker
Drilling Company and Parker Drilling Investment Company, (collectively,
"Parker") which provided for the acquisition by the Company, through it's wholly
owned subsidiary, National Fuel & Energy, Inc. ("NFE"), of Parker's 50% interest
in OnSite Technology L.L.C. ("OnSite") resulting in NFE becoming the owner of
100% of OnSite. Pursuant to the terms of the Purchase Agreement, the Company
paid $8,000,000 for the 50% interest and repaid a $3,000,000 loan that had been
made to the Company by an affiliate of Parker. As part of the transaction,
Parker returned to the Company 300,000 unexercised warrants to purchase the
Company's common stock. The acquisition was the result of negotiations between
the Company and Parker and was based on numerous factors including the Company's
estimate of the net worth of OnSite, and the future business prospects of
OnSite.
 
     The Company's sources of funds to effect the acquisition was the sale of
$8,000,000 of new Series B Convertible Preferred Stock and Series C Preferred
Stock and the borrowing of $6,000,000 from an investor group consisting of
Cahill, Warnock Strategic Partners Fund, L.P., Strategic Associates, L.P.,
Newpark Resources, Inc. and James H. Stone, who is the Chairman of Stone Energy
Corporation. Pursuant to this financing, the Company agreed to register the
shares of Common Stock underlying the Series B Convertible Preferred Stock and
the shares issuable upon exercise of certain warrants to acquire common stock of
the Company. Further, pursuant to the financing David L. Warnock was appointed
as a Director of the Company.
 
     As a result of the financing, the Company retained approximately $3,000,000
after the transaction to use for working capital, expenses associated with the
financing and general corporate purposes.
 
                                USE OF PROCEEDS
 
     The Company will not receive any proceeds upon the resale of the Common
Stock by the Selling Stockholders. In the event the shares of Common Stock are
issued upon exercise of all of the Warrants, the Company will receive as gross
proceeds from the exercise of the Warrants of $7,071.42 which it intends to
utilize to defray the expenses in connection with this offering. The Company
does not anticipate that any proceeds from this offering will be available after
the payment of such offering expenses. The Selling Stockholders will not pay any
of the costs of this Registration.

                              PLAN OF DISTRIBUTION
 
     The Selling Stockholders have advised the Company that the Stockholder
Shares may be sold or distributed from time to time by the Selling Stockholders,
their distributees or assignees, or by pledgees, donees or transferees of, or
other successors in interest to, the Selling Stockholders, directly to one or
more purchasers (including pledgees) or through brokers, dealers or underwriters
who may act solely as agents or may acquire Stockholder Shares as principals, at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices, at negotiated prices, or at fixed prices, which may be
changed. The distribution of the Stockholder Shares may be effected by one or
more of the following methods: (i) ordinary brokers' transactions, which may
include long or short sales; (ii) transactions involving cross or block trades
or otherwise on the American Stock Exchange; (iii) purchases by brokers, dealers
or underwriters as principals and resale by such purchasers for their own
accounts pursuant to this Prospectus; (iv) "at the market" to or through market
makers or into an existing market for the Common Stock; (v) in other ways not
involving market makers or established trading markets, including direct sales
to purchasers or sales effected through agents; (vi) through transactions in
options, swaps or other derivatives (whether exchange-listed or
 
                                       12
<PAGE>   15
 
otherwise); or (vii) any combination of the foregoing, or by any other legally
available means. In addition, the Selling Stockholders, their distributees or
assignees, or their successors in interest may enter into hedging transactions
with broker-dealers who may engaged in short sales of Common Stock in the course
of hedging the positions they assume with the Selling Stockholders. The Selling
Stockholders, their distributees or assignees, or their successors in interest
may also enter into option or other transactions with broker-dealers that
require the delivery to such broker-dealers of the Stockholder Shares, which
Stockholder Shares may be resold thereafter pursuant to this Prospectus.
 
     Brokers, dealers, underwriters or agents participating in the distribution
of the Stockholder Shares as agent may receive compensation in the form of
discounts, concessions or commissions from the Selling Stockholders (and, if
they act as agent for the purchaser of such Stockholder Shares, from such
purchaser). Such discounts, concessions or commissions as to a particular
broker, dealer, underwriter or agent might be greater or less than those
customary in the type of transaction involved.
 
     The Selling Stockholders and any brokers, dealers, underwriters or agents
that participate in the distribution of the Stockholder Shares may be deemed to
be "underwriters" within the meaning of the Securities Act, and any discounts,
commissions or concessions received by any such persons might be deemed to be
underwriting discounts and commissions under the Securities Act. Neither the
Company nor the Selling Stockholders can presently estimate the amount of such
compensation. The Company knows of no existing arrangements between any Selling
Stockholder and any other Selling Stockholder, broker, dealer, underwriter or
agent relating to the sale or distribution of the Stockholder Shares.
 
     To the extent required, the Company will file, during any period in which
offers or sales are being made, a supplement to this Prospectus which sets
forth, with respect to a particular offering, the specific number of Stockholder
Shares to be sold, the name of the Selling Stockholder, the sales price, the
name of any participating broker, dealer, underwriter or agent, any applicable
commission or discount and any other material information with respect to the
plan of distribution not previously disclosed.
 
     The Company will not receive any of the proceeds from the sale of the
Stockholder Shares offered hereby. The Company will pay substantially all of the
expenses incident to this Offering of the Stockholder Shares by the Selling
Stockholders to the public other than commissions and discounts of brokers,
dealers, underwriters or agents. The Company has agreed to indemnify certain of
the Selling Stockholders and certain related persons against certain
liabilities, including certain liabilities under the Securities Act.
 
     In order to comply with certain states' securities laws, if applicable, the
Stockholder Shares will be sold in such jurisdictions only through registered or
licensed brokers or dealers. In addition, in certain states the Common Stock may
not be sold unless the Common Stock has been registered or qualified for sale in
such state or an exemption from registration or qualification is available and
is satisfied.
 
     There is no assurance that the Selling Stockholders will sell any or all of
the Stockholder Shares.
 
                           DESCRIPTION OF SECURITIES
 
     The authorized capital stock of the Company consists of 50,000,000 shares
of common stock, $0.001 par value, and 10,000,000 shares of preferred stock,
$0.001 par value.
 
     The following summary description of the securities of the Company is
qualified in its entirety by reference to the Company's Articles of
Incorporation, Bylaws, Certificate of Designation, Preferences, Rights and
Limitations of Series B Convertible Preferred Stock and the Certificate of
Designation, Preferences, Rights and Limitations of Series C Preferred Stock
which are filed as exhibits to the Registration Statement of which this
Prospectus is a part. See, "Additional Information".
 
PREFERRED STOCK
 
     The Company's board of directors has authority, without action or consent
by the stockholders, to issue the authorized but unissued shares of Preferred
Stock in one or more series, to establish the number of shares to be included in
each series and to fix the designations, powers, preferences and rights of the
shares of each
                                       13
<PAGE>   16
 
such series and the qualifications, limitations or restrictions thereof. This
includes, among other things, voting rights, conversion privileges, dividend
rates, redemption rights, sinking fund provisions and liquidation rights which
shall be superior to the common stock.
 
     Series B Convertible Preferred Stock. The Company has authorized 5,000,000
shares of Series B Convertible Preferred Stock, of which 3,771,422 shares are
issued and outstanding. Series B Convertible Preferred Stock is entitled to
receive dividends at the same rate as dividends on Common Stock. Series B
Convertible Preferred Stock may be converted into fully paid and non-assessable
shares of the Company's Common Stock. The number of shares of Common Stock into
which each share of Series B Convertible Preferred Stock may be converted is
determined by multiplying the number of shares of Series B Convertible Preferred
Stock to be converted by $1.06 and dividing the result by the Conversion Price
which presently is $1.06. The conversion price is subject to adjustment under
certain conditions, which include, but are not limited to stock splits, stock
dividends, combinations or corporate reorganizations.
 
     Except for the election of directors, the shares of Series B Convertible
Preferred Stock shall be entitled to vote, together with the shares of the
Company's Common Stock, on all matters presented at any annual or special
meeting of stockholders of the Company, or may act by written consent in the
same manner as the holders of the Company's Common Stock, upon the following
basis: each holder of Series B Convertible Preferred Stock shall be entitled to
cast such number of votes for each share of Series B Convertible Preferred Stock
held by such holder on the record date fixed for such meeting, or on the
effective date of such written consent, as shall be equal to the number of
shares of the Company's Common Stock into which each of such holder's shares of
Series B Convertible Preferred Stock is convertible immediately after the close
of business on the record date fixed for such meeting or the effective date of
such written consent.
 
     So long as the Series B Convertible Preferred Stock is outstanding and
unconverted to Common Stock, the holders of the Series B Convertible Preferred
Stock, voting separately as a class, shall be entitled to elect one member of
the Board of Directors.
 
     In the event of any voluntary or involuntary liquidation, dissolution or
winding up of the Company, the holders of shares of Series B Convertible
Preferred Stock then outstanding are entitled to receive out of assets of the
Company available for distribution to stockholders, before any distribution of
assets is made to holders of any other class of capital stock of the Company, an
amount equal to $1.06 per share, plus accumulated and unpaid dividends thereon
to the date fixed for distribution. A consolidation or merger of the Company (in
the event that the Company is not the surviving entity) or sale of all or
substantially all of the Company's assets is regarded as a liquidation,
dissolution or winding up of the affairs of the Company.
 
     So long as twenty-five percent (25%) of the shares of Series B Convertible
Preferred Stock are outstanding, the Company shall not: (i) create, authorize or
issue shares of any class or series of stock, or any security convertible into
such class or series ranking senior to or on parity with the Series B
Convertible Preferred Stock either as to payment of dividends or as
distributions in the event of a liquidation, dissolution or winding up of the
Company; or (ii) amend, alter or repeal any provision of the Articles of
Incorporation or Bylaws of the Company so as to affect adversely the relative
rights, preferences, qualifications, limitations or restrictions (including,
without limitation, expanding the number of members on the Board of Directors)
of the Series B Convertible Preferred Stock; or (iii) declare or pay any
dividend on its Common Stock if any dividends are unpaid on the Series B
Convertible Preferred Stock; or (iv) redeem for cash any other securities issued
by the Company; or (v) directly or indirectly, enter into any merger,
consolidation or other reorganization in which the Company shall not be the
surviving Company, unless the surviving Company shall, prior to such merger,
consolidation or reorganization, agree in writing to assume the obligations of
the Company under the Certificate of Designation. The Company, however, is not
limited in its power to issue bonds, notes, mortgages, debentures, common stock,
preferred stock ranking junior to the terms of the Series B Convertible
Preferred Stock and other obligations, and to incur indebtedness to banks and to
other lenders.
 
     The Company has no right of redemption with respect to the Series B
Convertible Preferred Stock.
 
                                       14
<PAGE>   17
 
     Series C Preferred Stock. The Company has authorized 400,000 shares of
Series C Preferred Stock of which 400,000 shares are issued and outstanding.
Series C Preferred Stock is entitled to received dividends in an annual amount
equal to the prime rate plus one and one-half percent (1 1/2%) as reported by
NationsBank of Maryland, N.A. on the outstanding stated value of the Series C
Preferred Stock. The dividends are calculated as of the last day of each
quarter, and are payable quarterly in arrears with the first quarterly payment
due for the quarter ending March 31, 1998. The Series C Preferred Stock is not
convertible into the Company's Common Stock. Holders of Series C Preferred Stock
are not entitled to vote on any matters.
 
     In the event of any voluntary or involuntary liquidation, dissolution or
winding up of the Company, the holders of shares of Series C Preferred Stock
then outstanding shall be entitled to receive out of assets of the Company
available for distribution to stockholders, before any distribution of assets is
made to holders of any other class of capital stock of the Company, except
Series B Convertible Preferred Stock, an amount equal to $10.00 per share. A
consolidation or merger of the Company (in the event that the Company is not the
surviving entity) or sale of all or substantially all of the Company's assets
shall be regarded as a liquidation, dissolution or winding up of the affairs of
the Company.
 
     The Company, at its sole discretion, may redeem any and/or all of the
shares of Series C Preferred Stock as may be outstanding from time to time, upon
thirty (30) days written notice to the holders. The Redemption Price for each
share of Series C Preferred Stock shall be $10.00, plus accumulated and unpaid
dividends thereon to the date fixed for redemption. The redemption notice shall
provide for the date of redemption and the redemption price, along with the
number of shares of Series C Preferred Stock to be redeemed.
 
LIMITATION ON PAYMENT OF DIVIDENDS
 
     The Company may not, except for dividends payable in connection with the
Series C Preferred Stock, authorize or pay any dividends at any time if any
amount is unpaid with respect to the $6,000,000 Loan Agreement.
 
              LIMITATION ON DIRECTOR'S LIABILITY; INDEMNIFICATION
 
     The Articles of Incorporation of the Company ("Articles") provide, as
permitted by governing Nevada law, that a director of the Company shall not be
personally liable to the Company or its stockholders for monetary damages for
breach of fiduciary duty as a director, with certain exceptions. These
provisions may discourage stockholders from bringing suit against a director for
breach of fiduciary duty and may reduce the likelihood of derivative litigation
brought by stockholders on behalf of the Company against a director.
 
     The Articles provide that the Company will indemnify its directors and
officers against expenses and liabilities they incur to defend, settle, or
satisfy any civil litigation or criminal action brought against them on account
of their being or having been Company directors or officers unless, in such
action, they are adjudged to have acted with gross negligence or willful
misconduct.
 
     Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers, and controlling persons of the Company
pursuant to the forgoing provisions, or otherwise, the Company has been advised
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable.
 
     The inclusion of this provision in the Articles may have the effect of
reducing the likelihood of derivative litigation against directors, and may
discourage or deter stockholders or management from bringing a lawsuit against
directors for breach of their duty of care, even though such an action, if
successful, might otherwise have benefitted the Company and its stockholders.
 
     The Articles provide for the indemnification of its executive officers and
directors, and the advancement to them of expenses in connection with any
proceedings and claims, to the fullest extent permitted by the Nevada law. The
Articles include related provisions meant to facilitate the indemnities' receipt
of such benefits. These provisions cover, among other things: (i) specification
of the method of determining entitlement to indemnification and the selection of
independent counsel that will in some cases make such
 
                                       15
<PAGE>   18
 
determination, (ii) specification of certain time periods by which certain
payments or determinations must be made and actions must be taken, and (iii) the
establishment of certain presumptions in favor of an indemnitee.
 
                                 LEGAL MATTERS
 
     The validity of the Common Stock offered hereby will be passed on for the
Company by Axelrod Smith & Kirshbaum of Houston, Texas. Mr. Robert D. Axelrod
presently owns 25,759 shares of Common Stock of the Company.

     The Articles provide for the indemnification of its executive officers and
directors, and the advancement to them of expenses in connection with any
proceedings and claims, to the fullest extent permitted by the Nevada law. The
Articles include related provisions meant to facilitate the indemnitiees'
receipt of such benefits. These provisions cover, among other things: (i)
specification of the method of determining entitlement to indemnification and
the selection of independent counsel that will in some cases make such
determination, (ii) specification of certain time periods by which certain
payments or determinations must be made and actions must be taken, and (iii) the
establishment of certain presumptions in favor of an indemnitee.

ITEM 17. UNDERTAKINGS
 
     (a) The undersigned registrant hereby undertakes:
 
          (1) To file, during any period in which offer 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 the registration statement; and
 
             iii. To include any additional or changed material information with
        respect to the plan of distribution.
 
                                      II-2
<PAGE>   21
 
          (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.
 
        (4) i. That, for the purpose of determining liability under the
        Securities Act of 1933, the information omitted from the form of
        prospectus filed as part of this registration statement in reliance upon
        Rule 430A and contained in a form of prospectus filed by the registrant
        pursuant to Rule 424(b)(1) or (4), or 497(h) under the Securities Act of
        1933 shall be deemed to be part of this registration statement as of the
        time it was declared effective.
 
             ii. That, for the purpose of determining liability under the
        Securities Act of 1933, each post-effective amendment that contains a
        form of prospectus 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.
 
     (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 (the "Act") 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 Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

James S. Percell, President
Environmental Safeguards, Inc.
2600 South Loop West, Suite 645

Dear Mr. Percell:
 
     As counsel for Environmental Safeguards, Inc., a Nevada corporation
("Company"), you have requested our firm to render this opinion in connection
with the Registration Statement of the Company on Form S-3 ("Registration
Statement") under the Securities Act of 1933, as amended (the "Act"), filed with
the Securities and Exchange Commission relating to the resale of 6,582,505
shares of common stock, par value $.001 per share (the "Common Stock") by
certain security holders of the Company. Of these, 333,400 shares of Common
Stock are currently outstanding shares of the Company's Common Stock owned by
certain security holders of the Company in connection with a September, 1996
private placement. The Registration Statement also relates to the registration
of the issuance of up to 4,478,564 shares of common stock, par value $.001 per
share (the "Common Stock"), consisting of (i) 3,771,422 shares of Common Stock
underlying 3,771,422 shares of Series B Convertible Preferred Stock (the
"Preferred Stock"), and, (ii) 707,142 shares of Common Stock underlying 707,142
Warrants (the " Warrants"). Further, the Registration Statement also relates to
the post-effective registration amendment for shares of common stock, par value
$.001 per share (the "Common Stock") which were originally registered pursuant
to Form SB-2 effective with the Commission on February 11, 1997, of which
1,770,541 shares of common stock are the subject of the post-effective
amendment.
 
     We are familiar with the Registration Statement and the registration
contemplated thereby. In giving this opinion, we have reviewed the Registration
Statement and such other documents and certificates of public officials and of
officers of the Company with respect to the accuracy of the factual matters
contained therein as we have felt necessary or appropriate in order to render
the opinions expressed herein. In making our examination, we have assumed the
genuineness of all signatures, the authenticity of all documents presented to us
as originals, the conformity to original documents of all documents presented to
us as copies thereof, and the authenticity of the original documents from which
any such copies were made, which assumptions we have not independently verified.
 
     Based upon the foregoing, we are of the opinion that:
 
          1. The Company is a corporation duly organized, validly existing and
     in good standing under the laws of the State of Nevada; and
 
          2. The shares of Common Stock to be resold are validly authorized,
     validly issued, fully paid and nonassessable.
<PAGE>   2
 
          3. The shares of Common Stock underlying the Preferred Stock to be
     issued upon the conversion of such Preferred Stock are validly authorized
     and, upon conversion of the shares of Preferred Stock, in accordance with
     their terms, will be validly issued, fully paid and nonassessable.
 
          4. The shares of Common Stock underlying the Warrants to be issued
     upon exercise of such Warrants are validly authorized and, upon exercise of
     the Warrants in accordance with their terms, and when fully paid for, will
     be validly issued, fully paid and nonassessable.
 
     We consent to the to the filing of this opinion as an exhibit to the
Registration Statement and to the reference in the Registration Statement to
Axelrod, Smith, & Kirshbaum under the heading "Exhibits -- Opinion."
 
                                            Very truly yours,
 
                                             /s/ AXELROD, SMITH, & KIRSHBAUM
