ITEM 1. BUSINESS
 
INTRODUCTION
 
     Environmental Safeguards, Inc. (the "Company"), is engaged in the
development, production and sale of environmental remediation and recycling
technologies and services, primarily to oil and gas industry participants,
through its wholly-owned subsidiaries National Fuel & Energy, Inc. ("NFE") and
OnSite Technology, L.L.C. ("OnSite"). The environmental remediation and
recycling services provided by the Company involve the removal of hydrocarbon
contaminants and valuable drilling fluids from soil using indirect thermal
desorption remediation and recycling technology. The Company provides these
services on site. The Company does not haul remediated soil or recycled material
away from a site.
 
     Unless otherwise indicated, references to the Company include OnSite and
NFE, the Company's wholly owned subsidiaries. The Company's Common Stock is
traded on the American Stock Exchange under the symbol "EVV".
 
HISTORY
 
     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. , a Wyoming
corporation ("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.
 
     In January 1995, the Company entered into an agreement with Parker Drilling
Company ("Parker"), a Delaware corporation, granting Parker exclusive marketing
rights to the Company's proprietary processes for on-site remediation and
recycling services in connection with drill cuttings at oil and gas drilling
sites throughout the United States and in certain foreign countries. In August
1995, the Company expanded its agreement with Parker by forming OnSite, a joint
company between NFE and Parker, in which NFE and Parker each owned 50%. Pursuant
to its agreement with OnSite, NFE granted to OnSite certain exclusive licenses
to use the technologies relating to the Company's Indirect Thermal Desorption
Units (the "ITD Units"), and the proprietary processes for on-site remediation
and recycling of hydrocarbon contaminated soil.
 
     In December 1997, the Company entered into a Purchase Agreement (the
"Purchase Agreement") with Parker which provided for the acquisition by the
Company, through NFE, of Parker's 50% equity interest in OnSite resulting in NFE
becoming the owner of 100% of the equity interest in OnSite. Pursuant to the
terms of the Purchase Agreement, the Company paid $8,000,000 for the 50% equity
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
unexercised warrants to purchase 300,000 shares of the Company's common stock.
 
     The Company's sources of funds to effect the acquisition included the sale
of $8,000,000 of new Series B Convertible Preferred Stock and Series C Preferred
Stock to 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 and a secured loan of
$6,000,000 from the same investor group ("Loan Agreement"). Pursuant to the
financing, David L. Warnock, a member of Cahill, Warnock & Co., L.L.C. and
general partner of Cahill, Warnock Strategic Partners Fund, L.P., 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, payment of expenses associated
with the financing and general corporate purposes.

BUSINESS ACTIVITIES
 
     General. Substantially all of the Company's activities are conducted
through OnSite, which is engaged in the development and production of
remediation and recycling technology and the sale of environmental remediation
and recycling services. OnSite owns the technologies included in the 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 may be transported from one
clean-up site to another. The Company's customers are large corporations in the
oil and gas drilling industry that have responded to the changing regulatory
climate with respect to soil and other environmental contamination.
 
     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 site where the
contaminated soil is located. The Company does not haul or dispose of soil or
contaminants away from the customer's location.
 
     As of March, 1998, the Company owns four ITD Units. It operates three of
these ITD Units, one in Louisiana for Newpark Resources, Inc. ("Newpark
Resources"), one in Venezuela pending finalization of a contract with a major
oil and gas producer and one in Houston undergoing final internal quality
control testing and review. The fourth ITD Unit owned by the Company is leased
to OnSite Colombia, Inc. ("OnSite Colombia"), an affiliate in which the Company
owns a 50% interest. OnSite Colombia leases two additional ITD Units pursuant to
sale-leaseback arrangements with unrelated third parties. All three of the ITD
Units leased by OnSite Colombia are under contract to a multinational oil and
gas company operating in Colombia. Four additional ITD Units are under
construction by third parties, with delivery of the completed ITD Units expected
to begin in May, 1998, bringing the Company's fleet of portable units to 10.
There can be no assurance that delivery of the four ITD Units will be made
starting in May, 1998.
 
     Customers. The Company's customers are large oil and gas industry
participants. 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 and the estimated processing time. Once a
contract has been awarded, OnSite moves its equipment to the client's desired
location.
 
     Indirect Thermal Remediation and Recycling. The primary services offered by
the Company involve: (i) the remediation and recycling of soil contaminated by
oil-based drilling mud, fuel spills, leakage at storage tanks, leakage from
pipelines; (ii) the remediation and recycling of hydrocarbon contamination at
settling ponds, oil and gas exploration sites, refineries, petrochemical
facilities, abandoned production fields, Department of Defense installations and
other similar type sites; and (iii) the remediation and recycling of valuable
drilling fluids which have been captured in soil and drilling muds during the
drilling process. To date the Company has employed its ITD Units to provide
remediation and recycling services to oil and gas industry drilling operations,
tank farms and compressor sites. This process is known as "indirect thermal
desorption" because it reverses the contamination process and removes the
hydrocarbons from the soil and discharges the contaminants previously absorbed
without direct contact of the soil to a flame.
 
     The ITD Units are portable pieces of equipment which utilize a rotating,
heat-jacketed trundle to vaporize hydrocarbons from contaminated soil. An ITD
Unit consists of two principal components: (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
 
                                        4
<PAGE>   5
 
hydrocarbon vapor to condense to a liquid for client recycling. As an
alternative to the condensing system, the vapor can be passed through an
afterburner or thermal oxidizer which incinerates the hydrocarbon vapors.
 
     The heat exchange system is comprised of a large fabricated steel shell
which houses a rotating trundle. Hot gases pass through the shell and around the
outside surface of the trundle. Hydrocarbon contaminated soil is loaded into the
elevated end of the trundle by a conveyor belt or a front end loader. As the
trundle revolves, the soil is agitated by internal lifts and oars as it passes
through the inside of the trundle by gravity flow and is heated to temperatures
from 300 degrees to 1200 degrees Fahrenheit. At these temperatures, the
hydrocarbon contaminants in the soil transform into vapors which are vacuumed
out of the heat exchange system into the condensing system, the afterburner or
the thermal oxidizer. The clean soil then drops out of the discharge door at the
low end of the trundle and is passed through an enclosed conveyor for
rehydration before final discharge. Random soil samples are tested at the end of
the process to confirm that the contaminants have been removed and the soil
condition is within the permitted range. The soil is then returned to its
original location or such other location specified by the customer.
 
     The hydrocarbon vapors removed from the heat exchange system by vacuum are
passed through a fan-cooled condensing system. The vapors are condensed into
liquids and collected in storage tanks and can then be recycled or disposed,
depending on the nature of the contaminant, the needs of the customer and the
specifications required for reuse. To date, an ITD Unit has processed up to 192
tons of contaminated soil in a 24-hour period with a 30% hydrocarbon saturation.
However, the processing capacity varies significantly depending on the moisture
content, degree of contamination, soil type, contamination type and the
remediation and recycling required. There can be no assurance that the ITD Units
will continue to perform at this level, or that this performance will continue
to be competitive with other technology available in the market.
 
     Recycling of Hydrocarbon Contaminants. The Company has developed
proprietary processes which are embodied in the condensation process system
unit, one of the two principal components of the ITD Unit. Within this component
the hydrocarbon contaminant(s) are condensed from the vapor state created in the
dryer unit back into a liquid state via the proprietary processes and placed
into storage for recycling back to the client. This allows the client to realize
actual savings from its ability to re-utilize the hydrocarbons. This ability to
recycle the hydrocarbon contaminant(s) is an important competitive advantage
which the Company believes it possesses as compared to the bioremediation,
direct burn and "dig and haul" remediation technologies.
 
     Manufacturing of ITD Units. The Company contracts with outside fabricators
to manufacture ITD Units. The primary contractors which the Company uses are
Roberds-Johnson Industries, Cobrans Corporation, Stelcon, Inc. and Houston Pro
FAB. Currently, four ITD Units are under construction by fabricators for the
Company and the Company expects delivery of these four ITD Units beginning in
May 1998, but there can be no assurance that this will occur.
 
EXISTING CONTRACTS FOR OPERATIONS
 
     As of March, 1998, the Company operates three ITD Units. One is under
contract to Newpark Resources in Louisiana, one is in Venezuela pending
finalization of a contract with a major oil and gas producer and one is in
Houston undergoing final testing and review. OnSite Colombia operates three
additional ITD Units, all of which are currently under contract and in operation
for a multinational oil and gas company in Colombia.
 
COMPETITION
 
     There are many companies which currently dispose of hazardous and
industrial wastes and remediate 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
services. Many of the Company's competitors are well established and have
substantially greater capital resources, larger research and development staffs
and facilities and substantially greater marketing capabilities than the
Company. There can be no assurance that the Company will be competitive in the
soil remediation and recycling industry in the future.
                                        5
<PAGE>   6
 
     The Company obtains its contracts through competitive bidding and is in
direct competition with firms providing alternative means of, and utilizing
alternative technologies for, remediating environmental problems. The most
significant competition comes from firms utilizing "dig and haul," direct burn,
and bioremediation technology to remediate soil contamination.
 
     Companies utilizing the dig and haul method generally transport the
contaminated soil to other facilities for processing. The Company believes that
the technology utilized by the Company is competitive with dig and haul methods
because the Company's equipment is mobile, and thus, contaminated soil can be
remediated on location. The waste processing, remediation and recycling
businesses are, to a large extent, dependent upon and constrained by the costs
and regulations associated with transporting such wastes. More importantly, the
Company's remediation and recycling process addresses the latent liability
associated with the contamination at the site. The Company is currently
investigating techniques and technologies capable of evaporation of non-needed
liquids and ultra-filtration applications. There can be no assurance that the
Company will be able to develop or acquire such technology and skill or that, if
obtained, will be competitive with other alternatives available in the market.
 
     Companies utilizing direct burn technology use direct heat sources to
incinerate contaminants found in the soil. Because of the closed nature of the
heat transfer system, the ITD Unit can safely handle much higher concentrations
of contaminants than conventional direct burn methods. Conventional direct burn
methods process material with maximum contamination levels of 3% to 4% while the
ITD Unit has processed materials with contamination levels as high as 30%. In
addition, the portable nature of the ITD Unit permits it to be located at the
contamination site to process and replace the soil on location. ITD Units also
permit the customer to recapture certain valuable liquids which are otherwise
destroyed.
 
GOVERNMENTAL REGULATIONS -- COST OF COMPLIANCE
 
     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
the contamination of water or soil. Environmental laws regulate, among other
things, the transportation, storage, handling and disposal of waste.
Governmental regulations govern matters such as the disposal of residual
chemical wastes, operating procedures, waste water discharges, air emissions
fire protection, worker and community right-to-know, and emergency response
plans. 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 evaluation, remediation or
cleanup effort conducted by it, or for an accident which occurs in the course of
such remediation 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.
 
     The Company presently has the ability to deliver 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 removal from the soil.
 
     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. Moreover, site-related permits are generally the
responsibility of the customer, not the Company.

EMPLOYEES
 
     The Company has 18 full-time employees, eight of whom are in management
positions, including corporate and administrative operations. The Company
utilizes the services of an employee leasing firm, Business Staffing, Inc., for
all of its U.S. domiciled employees. None of the Company's employees are
represented by a union and the Company considers its employee relations to be
good.
 
SUBSEQUENT DEVELOPMENTS
 
     On February 12, 1998 the Company's Common Stock began trading on the
American Stock Exchange under the symbol "EVV".
 
TRANSFER AGENT AND REGISTRAR
 
     The co-transfer agents and registrars for the Common Stock of the Company
are Colonial Stock Transfer Company, Inc. ("Colonial Transfer") and Registrar
and Transfer Company. Colonial Transfer's address is 455 East 400 South, Suite
100, Salt Lake City, Utah 84111; (801) 355-5740.
 
ITEM 2. PROPERTIES
 
     The Company's principal executive offices are located in leased facilities
at 2600 South Loop West, Suite 645, Houston, Texas 77054, which consist of a
total of approximately 2,000 square feet. The current monthly rental for these
executive offices is $1,500. The lease for the executive offices will expire in
May 1998. The Company anticipates renewing the lease. The Company believes that
its offices are adequate for its present needs and that suitable space will be
available to accommodate its future needs.
 
ITEM 3. LEGAL PROCEEDINGS
 
     The Company was named as a defendant in 1993 by Goldfield Engineering and
Machine Works ("Goldfield"), styled as Huron, Inc dba Goldfield Engineering &
Machine vs Don Cox, et.al. Cause No. 930400525 in the fourth District Court of
Utah County, Utah. The litigation originally involved claims by Goldfield that
the Company owed additional compensation of approximately $150,000 for ITD Units
constructed which the Company believes did not meet required performance
criteria. The Company filed a counterclaim for $200,000 to obtain damages from
Goldfield. The Company has been advised that Goldfield filed a petition seeking
Chapter 11 Bankruptcy protection in 1994. A Notice of Automatic Stay was filed
in August, 1994, based on the Chapter 11 Petition in In Re Huron , et al filed
in the US Bankruptcy Court for the Central Division of Utah, Case No. 94A-20001.
In January, 1995, a Plan of Reorganization was confirmed by the Bankruptcy Court
whereby the Company received nothing and no adversary pleadings were filed
against the Company by Goldfield. The Company believes, after consultation with
counsel, that the risk of material financial exposure to the Company is remote.

DIVIDEND POLICY
 
     The Company has not paid, and the Company does not currently intend to pay
cash dividends on its Common Stock in the foreseeable future. The current policy
of the Company's Board of Directors is for the Company to retain all earnings,
if any, to provide funds for operation and expansion of the Company's business.
The declaration of dividends, if any, will be subject to the discretion of the
Board of Directors, which may consider such factors as the Company's results of
operations, financial condition, capital needs and acquisition strategy, among
others.
 
     The Company may not, except for dividends payable in connection with its
Series C Preferred Stock, authorize or pay any dividends at any time if any
amount is unpaid with respect to the Company's $6,000,000 Loan Agreement.
 
ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
     The following discussion should be read in conjunction with the Company's
consolidated financial statements and related notes included elsewhere in this
Report. See, Financial Statements.
 
OVERVIEW
 
     The Company is engaged in the development, production and sale of
environmental reclamation and recycling technologies and services. Substantially
all of the Company's technologies and services are provided through On-Site and
the Company is devoting substantially all of its efforts to the development of
markets for OnSite's services. The Company is currently providing reclamation
and recycling services to companies engaged in land-based oil and gas
exploration, and to offshore applications where drill cuttings are barged to an
accessible land based facility for recycling. Oil and gas exploration often
produces significant quantities of
 
                                        8
<PAGE>   9
 
petroleum-contaminated drill cuttings, from which the Company's Indirect Thermal
Desorption ("ITD") process can extract and recover the hydrocarbons as
re-useable or re-saleable liquids, and produce recycled soil compliant with
environmental regulations. The Company intends to expand the activities of
OnSite to include use of ITD technology to address hydrocarbon contamination
problems and hydrocarbon recycling and reclamation opportunities at heavy
industrial, refining and petrochemical sites, as well as at Superfund, DOD and
DOE sites.
 
     On December 17, 1997, the Company acquired the remaining 50% interest in
OnSite from Parker Drilling Co., giving the Company complete control of the ITD
technology owned by OnSite, and providing the Company with a wholly-owned
operating subsidiary that forms the cornerstone of the Company's future
operations. Total purchase consideration in the OnSite acquisition was financed
by the Company through a private placement of Convertible Preferred and
Preferred Stock, combined with senior secured notes and warrants to purchase
shares of the Company's Common Stock. The Company has included OnSite's
operating results in its statement of operations for the year ended December 31,
1997, as though the acquisition took place at the beginning of the year, and has
deducted as a separate line item the preacquisition earnings attributable to the
former 50% owner.
 
     For the past two years the Company has focused essentially all of its
attention on its now wholly owned business operations in OnSite. OnSite was
formed, as a 50/50 joint company with Parker, as a means for assembling the
capital necessary to build and improve the ITD Units and to generate market
awareness and acceptance of ITD technology. The Company expects that a
substantial portion of its revenues will continue to be generated from major oil
and gas industry participants operating in Columbia and other Latin American
countries. In December 1997, the Company reached an agreement with Newpark
Resources, Inc. to provide reclamation and recycling services in support of
offshore drilling activity in the Gulf of Mexico.
 
     In November 1996, OnSite formed a 50/50 joint company, OnSite Columbia,
Inc. ("OnSite Columbia") with a group of South American investors. OnSite
Columbia was established to provide hydrocarbon contaminated soil reclamation
and recycling services to oil and gas industry participants operating in
Columbia. OnSite Columbia's operations are included in the Company's
consolidated results in 1997 because the Company has effective management
control.
 
RESULTS OF OPERATIONS
 
     The Company's historical consolidated operating results have been
significantly affected by the acquisition of the remaining 50% interest in
OnSite. In order to make a more meaningful period-to-period comparison of the
Company's operating results, the table below compares historical results (on the
left side) and pro forma financial data (on the right side). Historical
financial data is based on the consolidated method of reporting for 1997
(adopted in December 1997), and is based on the equity method for 1996
consistent with historical reporting prior to the change to the consolidated
method. Pro forma financial data assumes the acquisition and related financing
transaction were consummated as of the beginning of the periods presented. The
pro forma data presents both 1997 and 1996 using the consolidated method of
reporting to enhance comparability. The pro forma results of operations are not
necessarily indicative of the results that would have
 
                                        9
<PAGE>   10
 
occurred had the acquisitions been consummated as of the beginning of the
periods presented or that might be attained in the future.

</TABLE>
 
     The pro forma consolidated net loss from 1997 and 1996 includes pro forma
interest expense of $1.1 million in each year, which is not necessarily
indicative of future years' expenses. For example, the Company is evaluating
additional equity financing which could be utilized to retire certain debt. In
such case, the incremental interest expense could be eliminated on a go-forward
basis, but there can be no assurances that the Company will be successful in
that effort.
 
     The pro forma consolidated net loss for 1997 and 1996 also includes in each
year pro forma expense of $151,000 additional depreciation expense resulting
from the adjustment of OnSite's ITD Units to fair value at the time of
acquisition (to be depreciated over a 4.5 year weighted average remaining
economic life of that equipment); and $407,000 amortization of engineering
design and developed technology costs, an intangible asset related to the
acquisition of the 50% interest in OnSite (to be amortized over an 8 year
estimated economic life).
 
     The pro forma data for 1997 excludes the $762,000 acquired research and
development writeoff and the $352,000 extraordinary charge from extinguishment
of debt, as these charges are one-time events.
 
COMPARISON OF HISTORICAL OPERATING RESULTS
 
     Summary. For the year ended December 31, 1997, the Company incurred a net
loss of $1,849,000 as compared to a 1996 net loss of $647,000. The $1,202,000
increase essentially resulted from a $352,000 extraordinary charge from
retirement of debt, a $762,000 write-off of acquired research and development in
connection with the Company's acquisition of OnSite, and the non-recurrence of a
$74,000 extraordinary gain on elimination of debt recorded in 1996.
 
     The following line-by-line comparison reflects 1997 using the consolidated
method of reporting (adopted as a consequence of the Company's acquiring the
remaining 50% of OnSite), whereas 1996 results use the equity method (the 1996
historical basis of reporting). (The pro forma comparison which follows the
 
                                       10
<PAGE>   11
 
historical comparison reflects both 1997 and 1996 under the consolidated method
in order to enhance comparability).
 
     Revenues and Gross Margin. Service revenue of $6.6 million for 1997 was
primarily generated by ITD Units under contract in Colombia. Gross margin for
1997 was $3.4 million, or 51% of revenue. In 1996, neither revenue nor gross
margin were reported, as the Company accounted for the operations of OnSite
under the equity method. (See comments under pro forma comparison for additional
details).
 
     Selling, General and Administrative ("SGA") Expense. SG&A expenses
increased by $1,565,000 compared with the amount reported in 1996 due in part to
OnSite being accounted for on the equity method in 1996. SGA expenses in 1997
were the result of increased operations in Colombia which increased from one ITD
Unit in operation in November 1996 to three ITD Units in full operation starting
in June 1997. The higher level of business activity also prompted personnel
additions and/or recruitment of more experienced personnel at the Corporate
level in such key areas as international operations, accounting/finance,
engineering design and procurement, and regulatory matters. The number of
management employees increased from four at the end of 1996 to six at the end of
1997.
 
     Research and Development ("R&D") Expense. The 1997 R&D expense is primarily
the writeoff of acquired research and development based on a valuation of
in-process technology that resulted from the acquisition of Parker Drilling
Company's 50% interest in OnSite.
 
     Interest Income. In 1997, the Company earned interest income from
investment of proceeds from long-term debt of $3 million received in the fourth
quarter of 1996, and investment of net proceeds of approximately $800,000 from
the company's Regulation D offering that closed in February 1997. During 1996
the Company had little excess cash to invest.
 
     Interest Expense. The 1997 increase to $466,000 resulted from increased
borrowing to finance the construction of additional ITD Units.
 
     Income Taxes. The Company's reported tax provision in 1997 primarily
relates to foreign income taxes incurred by OnSite Colombia, a 50% owned
consolidated subsidiary of OnSite. (The 1996 taxes were included in the loss
from investment in OnSite). The Company has incurred net operating losses
("NOLs") in the U.S. in recent years, which may be used to offset taxable income
reported in future periods. The NOLs and certain foreign tax credits associated
with the taxes paid in Colombia have generated deferred tax assets, but due to
uncertainties regarding the future realization of these assets, a valuation
allowance has been provided for the full amount of the deferred tax assets. The
Company is implementing tax planning strategies, which if successful, may result
in the Company recognizing these deferred tax assets in future periods, which
would significantly reduce the current effective tax rate. There can be no
assurances that the NOL and foreign tax credits will be utilizable.
 
     Elimination of Minority Interest. Minority interest for 1997 reflects the
50% minority ownership's interest in the 1997 net income of OnSite Colombia. In
1996, the Company accounted for its 50% ownership in OnSite Colombia using the
equity method (which excluded the minority ownership).
 
     Extraordinary Item. The extraordinary loss of $352,000 for 1997 resulted
from the writeoff of deferred financing costs that resulted from the early
repayment of the $3 million long-term debt due to Parker. This debt was repaid
in connection with the Company's acquisition of OnSite. The $74,000
extraordinary gain in 1996 also relates to elimination of debt.
 
COMPARISON OF CONSOLIDATED PRO FORMA OPERATING RESULTS
 
     Summary. The pro forma consolidated data presents 1997 and 1996 operating
results as if the acquisition and related financing transaction were consummated
as of the beginning of each year, and also presents OnSite for both years under
the consolidated method of reporting to enhance line-by-line comparability.
 
     The 1997 pro forma consolidated net loss of $2,028,000 indicates an
improvement of $352,000 as compared to the pro forma consolidated net loss of
$2,380,000 for 1996. The $352,000 improvement is due to $3,289,000 higher gross
margin from increased volume of ITD Units operating in Colombia, partially
offset by
                                       11
<PAGE>   12
 
increases of $1,135,000 in SGA expense, $1,183,000 in Colombian income tax and
$629,000 in minority interests (each resulting from higher revenues and business
activity).
 
     Following are line-by-line comparisons of 1997 to 1996 on a consolidated
pro forma basis, where variances are significant:
 
     Revenues and Gross Margin. The Company's consolidated pro forma revenues
for 1997 increased from $730,000 to $6,678,000 as a direct result of OnSite's
construction and subsequent deployment of additional ITD Units under contract
with a major oil and gas industry participant in Colombia.
 
     During 1997, based on the positive recycling and remediation results that
were initially achieved, the Company was able to expand the scope of its initial
contract in Colombia and increase, from one to three, the number of ITD Units
deployed there. In 1996, the Company had concentrated its efforts and resources
on a single contract in Lysite, Wyoming and on the construction and improvement
of its ITD and Ultra-filtration technology. The Lysite project provided valuable
feedback concerning ITD Unit performance. Such feedback formed the basis for
improvements which were made to the current Series 6000 ITD design.
 
     Consolidated pro forma gross margin reached $3,307,000 or 49% of revenue
during 1997, reflecting economies of scale from operating 2.3 average units per
month in Colombia throughout 1997 versus one unit for two months only in 1996.
 
     Selling, General and Administrative ("SGA") Expense. Pro forma consolidated
SGA expenses increased by $1,135,000, an increase of 85% over 1996, versus a
corresponding revenue increase of over 800%, which demonstrates the benefits
derived from economies of scale on profitability. The increased SGA included
additions to the Corporate staff of important skills (as discussed above in the
historical analysis).
 
LIQUIDITY AND CAPITAL RESOURCES
 
     During both 1997 and 1996, the Company raised additional debt and equity
capital to fund current operations, support the construction of ITD Units
necessary for its future growth, and acquire the remaining 50% of OnSite from
Parker. In December 1997, the Company raised $14 million in a private placement
of Series B Convertible Preferred Stock, non-convertible Series C Preferred
Stock, senior secured notes and warrants to purchase the Company's Common Stock.
The proceeds from this private placement were primarily used to fund the $8
million acquisition of OnSite, repay $3 million of long-term debt to a Parker
subsidiary, and provide the Company with capital resources to continue funding
current operations and planned capital expenditures. In the 1997 private
placement, the Company received $6 million in proceeds from senior secured notes
and a commitment by the investors for an additional $5 million of long-term
debt, provided that the Company remains in compliance with the loan covenants of
the secured notes.
 
     Prior to the $14 million in funding described above, in the first quarter
of 1997, the Company converted debt and related accrued interest totaling
$1,262,000 to equity and completed a Regulation D offering of its common stock.
The proceeds from these transactions, along with the $3 million long-term debt
proceeds raised by the Company in December 1996 were used to support operations
throughout most of 1997.
 
     During 1997 the Company arranged capital leasing with third party lenders
for two ITD Units operated in OnSite Colombia in order to improve cash flows.
The Company has and will continue to make capital expenditures for ITD Units,
and at December 31, 1997, had placed orders for four additional units at an
aggregate cost of approximately $4.6 million. The Company plans to finance
additional ITD Units through a combination of surplus operating cash flows,
additional third party sale leaseback transactions, bank term financing, and
potentially an additional sale of equity. There can be no assurances that the
Company will be able to obtain this additional financing.
 
     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
 
                                       12
<PAGE>   13
 
the course of conducting business abroad in an effort to minimize risks
associated with foreign exchange fluctuation and its affect on Company
profitability.
 
IMPACT OF YEAR 2000
 
     The Year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of the Company's
computer programs that have time sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in a system
failure or miscalculation causing disruption of business activities.
 
     Based on ongoing assessments, the Company believes that no significant
modifications of existing computer software will be required. The Company
believes that its computer systems will function property with respect to dates
in the year 2000 and thereafter. The Company's ITD units are not dependent on
computer software or hardware, and therefore the Year 2000 issue is not expected
to pose material operational problems. The Company also believes that costs
related to the Year 2000 issue will not be significant.
 
     The Company is currently assessing its relationships with significant
suppliers and major customers to determine the extent to which the Company is
vulnerable to any third party's failure to remedy their own Year 2000 issues.
Based on preliminary assessments, management believes that significant exposure
does not exist with respect to third parties.

Accountants on September 17, 1997.
 
     There were no disagreements between the Company and Ham, Langston & Brezina
whether resolved or not resolved, on any matter of accounting principles or
practices, financial statement disclosure or auditing

scope or procedure, which, if not resolved, would have caused them to make
reference to the subject matter of the disagreement in connection with their
report.
 
     The report of Ham, Langston & Brezina for the past two fiscal years did not
contain any adverse opinion or disclaimer of opinion, excepting a "going
concern" qualification, and was not qualified or modified as to uncertainty,
audit scope or accounting principles.
 
     The decision to change principal accountants was not submitted for approval
to the Board of Directors. The change was made by the Company's President, James
S. Percell, in order to provide for the Company's growing need for global
expertise in accounting and other business matters.
 
     Also, during the Company's two most recent fiscal years, and since then,
Ham, Langston & Brezina has not advised the Company that any of the following
exist or are applicable:
 
          (1) That the internal controls necessary for the Company to develop
     reliable financial statements do not exist, that information has come to
     their attention that has lead them to no longer be able to rely on
     management's representations, or that has made them unwilling to be
     associated with the financial statements prepared by management;
 
          (2) That the Company needs to expand significantly the scope of its
     audit, or that information has come to their attention that if further
     investigated may materially impact the fairness or reliability of a
     previously issued audit report or the underlying financial statements or
     any other financial presentation, or cause him to be unwilling to rely on
     management's representations or be associated with the Company's financial
     statements for the foregoing reasons or any other reason; or
 
          (3) That they have advised the Company that information has come to
     their attention that they have concluded materially impacts the fairness or
     reliability of either a previously issued audit report or the underlying
     financial statements for the foregoing reasons or any other reason.
 
     Prior to the engagement of Ernst & Young as independent auditors, the
Company had not consulted Ernst & Young regarding the application of accounting
principles to a specified transaction, either completed or proposed; or the type
of audit opinion that might be rendered on the Company's financial statements or
any other financial presentation whatsoever.
 
     Ham, Langston & Brezina has provided the Securities and Exchange Commission
with a letter agreeing to the disclosure contained herein.

DIRECTOR COMPENSATION
 
     The Company does not currently pay any cash director's fees, but it pays
the expenses, if any, of its directors in attending board meetings. In November,
1995, the Company issued to each of Messrs. Percell, Pate and Sharp an option to
purchase 800,000 shares of Common Stock of the Company at $0.60 per share. Each
option is fully vested and may be exercised at any time until the option
terminates on November 2, 2005.
 
EMPLOYEE STOCK OPTION PLAN
 
     While the Company has been successful in attracting and retaining qualified
personnel, the Company believes that its future success will depend in part on
its continued ability to attract and retain highly qualified personnel. The
Company pays wages and salaries which it believes are competitive. The Company
also believes that equity ownership is an important factor in its ability to
attract and retain skilled personnel, and the Board of Directors of the Company
may adopt an employee stock option program.
 
     The purpose of the stock option program will be to further the interest of
the Company, its subsidiaries and its stockholders by providing incentives in
the form of stock options to key employees and directors who contribute
materially to the success and profitability of the Company. The grants will
recognize and reward outstanding individual performances and contributions and
will give such persons a proprietary interest in the Company, thus enhancing
their personal interest in the Company's continued success and progress. This
program will also assist the Company and its subsidiaries in attracting and
retaining key employees and directors.

Board of Directors and Stockholders
Environmental Safeguards, Inc.
 
     We have audited the accompanying consolidated balance sheet of
Environmental Safeguards, Inc. as of December 31, 1997, and the related
statements of operations, stockholders' equity and cash flows for the year then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of
Environmental Safeguards, Inc. as of December 31, 1997, and the results of its
operations and its cash flows for the year then ended in conformity with
generally accepted accounting principles.

                         ENVIRONMENTAL SAFEGUARDS, INC.
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
     Environmental Safeguards, Inc. (the "Company") provides environmental
remediation and hydrocarbon reclamation/recycling services principally to oil
and gas companies, using proprietary Indirect Thermal Desorption ("ITD")
technology. To date the primary service offered by the Company has been the
remediation of soil contaminated by oil based drill cuttings and the subsequent
recovery of diesel and synthetic oils which were in the drill cuttings.
Substantially all of the Company's operations to date have been conducted in
Colombia.
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its majority owned or controlled subsidiaries after elimination of all
significant intercompany accounts and transactions. (See Note 4)
 
  Management Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates. These estimates mainly involve the useful lives of property and
equipment, the valuation of deferred tax assets and the realizability of
accounts receivable.
 
  Research and Development
 
     Research and development activities are expensed as incurred, including
costs relating to patents or rights which may result from such expenditures.
 
  Revenue Recognition
 
     Revenue is recognized at the time services are performed or when products
are shipped.
 
  Concentrations of Credit Risk
 
     Financial instruments which subject the Company to concentrations of credit
risk include cash and accounts receivable. The Company maintains its cash in
well known banks selected based upon management's assessment of the banks'
financial stability and international capability. Balances periodically exceed
the $100,000 federal depository insurance limit; however, the Company has not
experienced any losses on deposits. Accounts receivable generally arise from
sales of services to multinational energy companies operating in the United
States and South America. Collateral is generally not required for credit
granted. Essentially all of the Company's trade receivables were due from one
multinational energy company for services performed in Colombia. Management
believes that all receivables are fully collectible.
 
  Cash Equivalents
 
     For purposes of reporting cash flows, the Company considers all short-term
investments with an original maturity of three months or less to be cash
equivalents.

                         ENVIRONMENTAL SAFEGUARDS, INC.
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Property and Equipment
 
     Property and equipment is stated at cost. Depreciation is computed
principally by the straight-line method over the estimated useful lives of 5
years for ITD Units, 7 years for office furniture and equipment, and 3 to 7
years for transportation and other equipment.
 
  Income Taxes
 
     The Company uses the liability method in accounting for income taxes. Under
this method, deferred tax assets and liabilities are determined based on
differences between financial reporting and income tax carrying amounts of
assets and liabilities and are measured using the enacted tax rates and laws
that will be in effect when the differences are expected to reverse.
 
  Stock-Based Compensation
 
     The Company accounts for its stock compensation arrangements under the
provisions of APB 25, Accounting for Stock Issued to Employees.
 
  Acquired Engineering Design and Technology
 
     Acquired engineering design and technology represents the intangible value
associated with certain proprietary equipment and process designs acquired by
the Company in the acquisition of OnSite (See Note 2). This intangible asset is
being amortized over an estimated useful life of 8 years using the straight-line
method. As of December 31, 1997, the accumulated amortization was $18,000.
 
  Fair Value of Financial Instruments
 
     The Company includes fair value information in the notes to financial
statements when the fair value of its financial instruments is different from
the book value. When the book value approximates fair value, no additional
disclosure is made.
 
  Reclassifications
 
     Certain prior year amounts in the 1996 consolidated balance sheet have been
reclassified to conform to the 1997 presentation. In December 1996, the Company
issued stock warrants in connection with the funding of certain long-term debt
with Parker Drilling Company ("Parker"). These warrants were assigned a value of
zero at the date of issuance but should have been valued at approximately
$460,000 with a related increase to additional paid-in capital. The accompanying
December 31, 1996 financial statements include a reclassification of the value
assigned to stock warrants. This reclassification had no impact on the statement
of operations. In addition, certain amounts in the 1996 statement of operations
have been reclassified to conform to the 1997 presentation.
 
  Recently Issued Pronouncements
 
     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income". SFAS No. 130 establishes standards for reporting and display of
comprehensive income and its components (revenues, expenses, gains and losses)
in a full set of general-purpose financial statements. It requires (a)
classification of the components of other comprehensive income by their nature
in a financial statement and (b) the display of the accumulated balance of the
other comprehensive income separate from retained earnings and additional
paid-in capital in the equity section of a statement of financial position. SFAS
130 is effective for years beginning after December 15, 1997 and is not expected
to have a material impact on financial position or results of operations.

2. ACQUISITION OF ONSITE TECHNOLOGY, L.L.C.
 
     On December 17, 1997, the Company acquired Parker Drilling Company's 50%
interest in OnSite Technology, L.L.C. ("OnSite") and, accordingly, OnSite became
a wholly-owned consolidated subsidiary of the Company. Prior to this
transaction, the Company accounted for its 50% ownership interest in OnSite on
the equity method. The $8 million purchase price and the required repayment of
$3 million of long-term debt due to a Parker subsidiary was financed through a
private placement of Series B convertible preferred stock, Series C preferred
stock, senior secured notes, and warrants for shares of the Company's common
stock. This acquisition has been accounted for using the purchase method of
accounting and the results of operations of OnSite have been consolidated with
the Company's for the year ended December 31, 1997 with a deduction in the
consolidated statement of operations for preacquisition earnings attributable to
Parker's interest prior to December 17, 1997.
 
     The $8 million purchase price has been allocated to the assets acquired and
liabilities assumed based on independent valuation. Approximately $762,000 of
the purchase price was allocated to research and development activities which
had not yet reached technological feasibility. This amount has been included in
the Company's 1997 consolidated statement of operations as acquired research and
development. The following is a summary of assets acquired and liabilities
assumed in the purchase.

     The Company presently contracts with one fabricator for the manufacture of
ITD Units and one fabricator for the manufacture of Condensing Units used in the
Company's operations. As of December 31, 1997, the Company had 1 ITD Unit and 2
Condensing Units in process at a cost of $1,338,000 with an expected cost to
complete of approximately $140,000. An unexpected disruption of the fabricator's
ability to timely deliver ITD Units could cause a delay in the Company's ability
to meet future service orders. Should a delay occur, the Company has taken steps
to facilitate the placement of orders with alternative fabricators.

Investor Notes or February 17, 2000, provided, however, that if the Investor
Notes are repaid in full prior to February 17, 2000, then no additional warrants
would be issued, and further provided that if a portion of the Investor Notes
are repaid prior to February 17, 2000, then warrants for a number of shares of
Common Stock of the Company would be issued on a pro rata basis.

     The Company consolidates its 50% owned subsidiary, OnSite Colombia, Inc., a
Cayman Island company that conducts operations in Colombia. The Cayman Island
imposes no income tax on such operations. However, the operations in Colombia
are subject to Colombian federal and local taxes. Accordingly, the Company has
included in its financial statements the Colombian income tax expense related to
such operations.
 
     The differences between the Federal statutory income tax rates and the
Company's effective income tax rates were as follows:

9. STOCKHOLDERS' EQUITY
 
     The Company's articles of incorporation authorize the issuance of up to
10,000,000 shares of preferred stock with characteristics determined by the
Company's board of directors. Effective December 17, 1997, in connection with
the Company's acquisition of OnSite, the board of directors authorized the
issuance and sale of up to 5,000,000 shares of Series B convertible preferred
stock and up to 400,000 shares of Series C preferred stock.
 
  Series B Convertible Preferred Stock
 
     The Company issued 3,771,422 shares of $0.001 par value Series B
convertible preferred stock. Dividends are paid at the same rate as common stock
based upon the conversion rate. The initial rate is 1 common share for each
preferred share; however, the conversion rate is subject to adjustments to
prevent dilution. The Series B convertible preferred stock has a liquidation
preference of $1.06 per share plus any unpaid dividends.
 
  Series C Preferred Stock
 
     The Company issued 400,000 shares of Series C non-voting preferred stock
with a $0.001 per share par value and a $10 per share stated value. The Series C
preferred stock carries a quarterly dividend payable in arrears of prime (8.5%
at December 31, 1997) plus 1.5% based on the stated value of the stock. The
Series C preferred stock is redeemable at the option of the Company at a price
of $10 per share plus any unpaid dividends.
 
  Common Stock
 
     In February 1997, the Company completed a public registration of 2,304,792
shares of its common stock. The Company's 10% convertible debentures provided
for automatic conversion into shares of the Company's common stock upon the
effective registration by the Company of its common stock under the Securities
Exchange Act of 1934, as amended. Of the 2,304,792 shares registered, 1,934,792
were newly issued shares for conversion of the 10% debentures and payment of
related accrued interest.
 
     In February 1997, the Company closed an exempt offering under Regulation D
of the Securities Act of 1933. The Company collected cash proceeds of $833,500
for the issuance of 333,400 shares of common stock ($688,500 collected in 1996
and $145,000 in 1997).
 
     In February 1996, the Company closed an exempt offering under Regulation D
of the Securities Act of 1933. The Company collected cash proceeds of $700,000
for issuance of 875,000 shares of common stock ($290,000 collected in 1995 and
$410,000 in 1996).
 
  Unissued Common Stock
 
     Unissued common stock at December 31, 1997 and 1996 represents shares for
which cash proceeds or other consideration had been received but shares had not
been issued.
 
  Stock Options
 
     The Company periodically issues incentive stock options to key employees,
officers, and directors to provide additional incentives to promote the success
of the Company's business and to enhance the ability to attract and retain the
services of qualified persons. The issuance of such options are approved by the
Board of

Directors. The exercise price of an option granted is determined by the fair
market value of the stock on the date of grant.
 
     The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" (APB 25) and related
Interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FASB
Statement No. 123, "Accounting for Stock-Based Compensation", requires use of
option valuation models that were not developed for use in valuing employee
stock options. Under APB 25, because the exercise price of the Company's
employee stock options is greater than or equals the market price of the
underlying stock on the date of grant, no compensation expense has been
recognized.
 
     Proforma information regarding net income and earnings per share is
required by Statement 123, and has been determined as if the Company had
accounted for its employee stock options under the fair value method of that
Statement. The fair value for these options was estimated at the date of grant
using a Black-Scholes option pricing model with the following weighted-average
assumptions for 1997 and 1996: risk-free interest rate of 6%; no dividend yield;
weighted average volatility factor of the expected market price of the Company's
common stock of 0.698; and a weighted-average expected life of the options of 5
years.
 
     The Black-Scholes option valuation model was developed for use in
estimating fair value of traded options which have no vesting restrictions and
are fully transferable. In addition, option valuation models require the input
of highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.
 
     For purposes of proforma disclosures, the estimated fair value of the
options is included in expense at the date of issuance because the options may
be fully exercised at that date. The Company's proforma information follows:

     All warrants outstanding at December 31, 1997 were issued in connection
with the sale of the Company's Series B and Series C preferred stock and the
funding of the Investor Notes (See Note 5). The warrants bear an exercise price
of $0.01 per share, are currently exercisable, and expire in December 2007.
 
10. EARNINGS PER SHARE
 
     For the years ended December 31, 1997 and 1996, due to the fact that the
Company incurred net losses, all common stock equivalents have been excluded
from the calculation of earnings per share because their effect is
anti-dilutive. In future periods, the calculation of diluted earnings per share
may require that the common stock equivalents disclosed in Note 9 be included in
the calculation of the weighted average shares outstanding for periods in which
net income is reported, using the treasury stock method. Following is the
reconciliation of net loss to the net loss available to common stockholders.

11. RESEARCH AND DEVELOPMENT
 
     During the year ended December 31, 1997, expenditures for research and
development were $786,000, which includes approximately $762,000 of acquired
research and development (See Note 2). During the year

                         ENVIRONMENTAL SAFEGUARDS, INC.
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
ended December 31, 1996, all research and development was conducted by OnSite
and such expenses are not included separately in the 1996 consolidated financial
statements as OnSite was accounted for under the equity method.
 
12. MAJOR CUSTOMERS
 
     During the years ended December 31, 1997 and 1996, the Company provided
services to only two customers and each accounted for more than 10% of service
revenue.
 
13. LITIGATION
 
     The Company is involved as a defendant in certain litigation filed by an
engineering company (the "Engineering Company") that constructed certain soil
remediation units for the Company. The litigation originally involved claims by
the Engineering Company that the Company owed additional compensation of
approximately $150,000 for units which the Company believes did not meet
required performance criteria. The Company filed a counter claim for $200,000 to
obtain damages from the Engineering Company. The Company has been advised that
in 1994, the Engineering Company filed a petition seeking Chapter 11 Bankruptcy
Protection. A Notice of Automatic Stay was filed in August 1994. In January
1995, the Engineering Company filed a Plan of Reorganization with the Bankruptcy
Court whereby the Company received nothing and no adversary pleadings were filed
against the Company. The Company believes, after consultation with legal
counsel, that the risk of material financial exposure to the Company is remote.
 
14. RELATED PARTY TRANSACTIONS
 
     The Company and OnSite share office facilities and certain employees.
Shared costs are generally specifically identified by company; however, certain
costs must be allocated based upon management's estimates. The operations of the
Company and OnSite were combined during the year ended December 31, 1997 in a
manner described in Note 4. However, during the period from January 1, 1997
through December 17, 1997 and the year ended December 31, 1996, 50% of OnSite's
operations were attributable to Parker, the former owner of a 50% interest in
OnSite.

                         ENVIRONMENTAL SAFEGUARDS, INC.


     We, the undersigned President and Assistant Secretary of Environmental

     article of incorporation as follows:

     Article IV is hereby amended (i) give effect to a 10 for 1 forward split
     of the Common Shares; (ii) decrease the post-reverse split authorized

          consisting of 10,000,000 shares of preferred stock, par value $0.001
          per share (hereinafter the "Preferred Stock"), and 50,000,000 shares

          be alike in every particular, except that there may be different
          dates from which dividends thereon, if any, shall be cumulative; if
          made cumulative. The powers, preference and relative, participating,
          optional and other rights of each such series, and the
          qualifications, limitations or restrictions thereof, if any, may
          differ from those of any and all other series at any time
          outstanding. Except as hereinafter provided, the Board of Directors
          of this corporation is hereby expressly granted authority to fix, by
          resolution or resolutions adopted prior to the issuance of any shares
          of each particular series of Preferred Stock, the designation,
          powers, preferences and relative, participating, optional and other
          rights, and the qualifications, limitations and restrictions thereof,
          if any, of such series, including but without limiting the generality
          of the foregoing, the following:

               the Board of Directors;
                    
                    (ii)  the rate and times at which, and the terms and
               conditions upon which, dividends, if any, on shares of the

certificate, or the certificate shall have a statement that the corporation
will furnish to any stockholders upon request and without charge, a full or

cease to be such officer or officers of the corporation, whether because of
death, resignation, or otherwise, before such certificate or certificates shall
have been delivered by the corporation, such certificate or certificates may
nevertheless be adopted by the corporation and be issued and delivered as
though the person or persons who signed such certificate or certificates, or
whose facsimile signature or signatures shall have been used thereon, had not
ceased to be the officer or officers of such corporation.

                               LOST CERTIFICATES

new certificate or certificates, the board of directors may, in its discretion
and as a condition precedent to the issuance thereof, require the owner of such
lost or destroyed certificate or certificates, or his legal representative, to
advertise the same in such manner as it shall require and/or give the
corporation a bond in such sum as it may direct as indemnity against any claim
that may be made against the corporation with respect to the certificate
alleged to have been lost or destroyed.

                           The obligation of each Lender to make the Initial
Loan is several and is limited to its Committed Amount, and such obligation of
each Lender is herein called its "Loan Commitment". The Loan Commitment of each
of the Lenders are herein collectively referred to as the "Loan Commitments".
The Agent shall not be responsible for the Commitment of any Lender; and
similarly, none of the Lenders shall be responsible for the Commitment of any
of the other Lenders; the failure, however, of any Lender to perform its
Commitment shall not relieve any of the other Lenders from the performance of
their respective Commitments.

                  (b) The Loan shall be evidenced by and payable in accordance
with a term note (the "Note" and collectively, the "Notes") in the form of

agree that they are prohibited from obtaining the Supplemental Loan in the
event that they are in default on the Initial Loan. The obligation of each
Lender to make a Supplemental Loan is several and shall be determined by
agreement among the Lenders, and if no agreement can be reached among Lenders,
then the obligation of each Lender to make a Supplemental Loan shall be
consistent with its respective Pro Rata Share on the Initial Loan. The Agent
shall not be responsible for a Commitment of any Lender; and similarly, none of
the Lenders shall be responsible for the Commitment of any of the other
Lenders; the failure, however, of any Lender to perform its Commitment under
the Supplemental Loan shall not relieve any of the other Lenders from the
performance of their respective Commitments. The terms of the Supplemental Loan
with respect to Maturity Date, interest, payments, late charges, Events of
Default, etc. shall be the same for the Supplemental Loan as it is for the
Initial Loan.

plus one and five-tenths percent (1.5%). Interest shall accrue daily on the
aggregate outstanding principal balance of the Loan for the period commencing
on the date the Loan is made until the Loan is paid in full.

                  (b) If not earlier paid, or if not accelerated for payment,
each Loan shall be payable to each Lender (for its Pro Rata Share), with notice
of such payment to the Agent, quarterly in arrears in substantially equal
periodic installments consisting of principal plus interest accrued at the rate
set forth in the Note, on the fifth (5th) day of each March, June, September
and December (each an "Interest Payment Date"), commencing on March 5, 1998,

accrued thereon due and payable on the Maturity Date.

         2.3.     Payments.

                  (a) Principal and interest shall be payable in lawful money
of the United States of America without set-off, deduction or counterclaim to
each of the Lenders (for its Pro Rata Share) at each Lender's principal
business office not later than 10:00 a.m. local time for each Lender on the
date on which such payment shall become due (each such payment made after such
time on such due date to be deemed to have been made on the next succeeding
Business Day).

                  (b) The payments shall be made to the addresses and accounts
as set forth in Schedule 2.3.

         2.4. Late Charges. Any principal or interest payment due under any
Note not paid within five (5) days from the date such payment is due, by
acceleration, conversion or otherwise, shall, to the extent permitted by law,
be subject to an additional interest charge equal to five percent (5%) above
the then prevailing interest rate under the Note. The charging or collection of
any late charge shall not be deemed a waiver of any of Agent's and/or Lenders'
rights arising thereby or hereunder, including Agent's right to declare an
"Event of Default" hereunder.

         2.5.     Prepayment; No Revolver.

                  (a) Borrowers may prepay all of the Loans with accrued
interest thereon, or any part of the Loans with accrued interest thereon in
increments of One Million Dollars ($1,000,000), at any time (except as provided
in Section 2.5(d)) by payment in cash of the Pro Rata Share to each of the
Lenders, with a notice of such payment to the Agent, without premium or
penalty. Such payment shall be made by 12:00 noon local time of each Lender on
any Business Day.

                  (b) Borrowers shall give Agent notice of prepayment hereunder
not less than thirty (30) days prior to the date of the prepayment. Such notice
shall specify the Loans to be prepaid and the amount of the Loans to be prepaid
and the date of prepayment (which shall be a Business Day).

                  (c) Amounts paid or prepaid on account of the Loans may not
be reborrowed.

                  (d) Borrowers hereby agree that they shall not make any
prepayments on the Loans unless and until EVSF shall have redeemed any and all
of the shares of Series C Preferred Stock as may be outstanding from time to
time.

and in good standing under the laws of its state of incorporation or
organization and has the requisite power to own, lease and operate its
properties and to carry on its business as now being conducted. Borrower is
duly qualified to do business and is in good standing in each jurisdiction in
which the character or location of the properties owned or leased by Borrower
or the nature of the business conducted by Borrower makes such qualification
necessary or advisable, except where the failure to do so would not be material
to the Company.

         5.2. Power and Authority. Borrower has the requisite power to execute,
deliver and perform the Loan Documents, and to consummate the transactions
contemplated thereby. The execution and delivery of the Loan Documents by
Borrower and the consummation of the transactions contemplated thereby have
been duly authorized by all necessary corporate or company action on the part
of Borrower. Each of the Loan Documents has been duly executed and delivered by
Borrower and constitutes a legal, valid and binding obligation of Borrower and
is enforceable against Borrower in accordance with its terms except (i) that
such enforcement may be subject to bankruptcy, insolvency, moratorium or
similar laws affecting creditors' rights and (ii) that the remedy of specific
performance and injunctive and other forms of equitable relief are subject to
certain equitable defenses and to the discretion of the court before which any
proceedings therefor may be brought. No consent or approval of any Person
(including, without limitation, any stockholder or member approval), no consent
or approval of any landlord or mortgagee and no waiver of any Lien is required
in connection with execution, delivery or performance by Borrower, or the
validity, enforcement or priority, of the Loan Documents or any Lien created
and granted thereunder.

         5.3. No Violation. The execution and delivery of the Loan Documents by
Borrower do not, and the performance of the Loan Documents will not, (i)
conflict with or result in a breach of the certificate or articles of
incorporation or bylaws or other formation documents of Borrower, or (ii)
violate, or conflict with, or constitute a default under, or (except for Liens
created pursuant to the Loan Documents) result in the creation or imposition of
any security interest, mortgage, pledge, lien, encumbrance, claim, restriction,
or other charge upon any property or assets of Borrower under any mortgage,
indenture or agreement to which Borrower is a party or by which the property or
assets of Borrower is bound, or (iii) violate any Requirement of Law, the
effect of which violation would be material and adverse to the business, assets
or financial condition of Borrower, or (iv) violate any permit, concession,
grant, franchise, license, or other governmental authorization or approval
necessary for the appropriate conduct of the business of Borrower, the effect
of which violation would be material and adverse to the business, assets or
financial condition of Borrower.

         5.4. Litigation. Except as provided in Schedule 5.4 hereto, there are
no actions, suits, proceedings or governmental investigations or inquiries
pending, or to the knowledge of Borrower threatened against Borrower or any of
its Affiliates or their respective properties, assets, operations or businesses
(i) that might prevent or interfere with the consummation of the transactions
contemplated hereunder or (ii) that might, singly or in the aggregate, result
in any

material adverse effect on the prospects, results of operation, properties,

there has been no material adverse change in the assets, business, financial
condition or prospects of Borrower.

         5.6. Compliance with Licenses and Laws. Except as disclosed in writing
to Agent by Borrower, Borrower possesses all Permits, and Borrower is in
compliance with the Permits and all Requirements of Law except where the
failure to possess any Permits or the failure to be in compliance with the
Permits or Requirements of Law would not, singly or in the aggregate, have a
material adverse effect on the business, assets, financial condition or
operations of Borrower. There are no proceedings pending or, to the knowledge
of Borrower, threatened that may result in the revocation, cancellation, or
suspension or any materially adverse modification of any of the aforementioned
Permits. Borrower has not received any written notice to the effect that, or
otherwise been advised that, it is not in compliance with any Permit or
Requirement of Law. Except as set forth in Schedule 5.6 hereto, no consent,
approval or authorization of, or declaration, filing or registration with, any
United States federal, state, or local governmental or regulatory authority, or

be obligated on the terms set forth herein for performance of its express
obligations hereunder, and except that the Agent shall be liable with respect
to its own gross negligence or willful misconduct. The Agent shall not be
liable for any apportionment or distribution of payments made by it in good
faith and if any such apportionment or distribution is subsequently determined
to have been made in error the sole recourse of any Lender to whom payment was

shall have no obligation to take any action if it, in good faith believes that
such action exposes the Agent to any liability.

         The Agent shall be entitled to rely upon any written notices,
statements, certificates, orders or other documents or any telephone message or
other communication (including any writing, telex, telecopy or telegram)
believed by it in good faith to be genuine and correct and to have been signed,
sent or made by the proper Person, and with respect to all matters pertaining
to this Agreement or any of the Loan Documents and its duties hereunder or
thereunder, upon advice of counsel selected by it. The Agent may deem and treat
the original Lenders as the owners of the respective Notes for all purposes
until receipt by the Agent of a written notice of assignment, negotiation or
transfer of any interest therein by the Lenders in accordance with the terms of
this Agreement. Any interest, authority or consent of any holder of any of the
Notes shall be conclusive and binding on any subsequent holder, transferee, or
assignee of such Notes. The Agent shall be entitled to rely upon the advice of
legal counsel, independent accountants, and other experts selected by the Agent

Section 8.8(a), each Lender agrees to confirm in writing, upon request by the
Borrowers, the authority to release any property covered by this Agreement or

Borrower, the Agent shall (and is hereby irrevocably authorized by the Lenders
to) execute such documents as may be necessary to evidence the release of the
Liens granted to the Agent for the benefit of the Lenders herein or pursuant
hereto upon such Collateral; provided, however, that (i) the Agent shall not be
required to execute any such document on terms which, in the Agent's opinion,
would expose the Agent to liability or create any obligation or entail any
consequence other than the release of such Liens without recourse or warranty,
and (ii) such release shall not in any manner discharge, affect or impair the
Obligations or any Liens upon (or obligations of any Person, in respect of),

property covered by this Agreement or the Loan Documents.

or any other Person to assure that the property covered by this Agreement or
the Loan Documents exists or is owned by Borrower or is cared for, protected or
insured or has been encumbered or that the Liens granted to the Agent on behalf
of the Lenders herein or pursuant hereto have been properly or sufficiently or
lawfully created, perfected, protected or enforced or are entitled to any
particular priority, or to exercise at all or in any particular manner or under
any duty of care, disclosure or fidelity, or to continue exercising, any of the
rights, authorities and powers granted or available to the Agent in this
Section 8.8(c) or in any of the Loan Documents, it being understood and agreed
that in respect of the property covered by this Agreement or the Loan Documents
or any act, omission or event related thereto, the Agent may act in any manner
it may deem appropriate, in its discretion, given the Agent's own interest in

and that the Agent shall have no duty or liability whatsoever to any of the
other the Lenders.

Lender (other than the Agent) obtain possession of any such Collateral,

                                       40

such Lender shall notify the Agent thereof, and. promptly upon the Agent's
request therefor, shall deliver such Collateral to the Agent or in accordance
with the Agent's instructions.

      8.10.       Exercise of Remedies.

such rights and remedies may be exercised only by the Agent.

      8.11.       Consents.

         (a) In the event the Agent requests the consent of a Lender and does
not receive a written denial thereof, or a written notice from a Lender that
due course consideration of the request requires additional time, in each case,
within ten (10) Business Days after such Lender's receipt of such request, then
such Lender will be deemed to have given such consent.

         (b) In the event the Agent requests the consent of a Lender and such
consent is denied, then Cahill, Warnock Strategic Partners Fund, L.P. may, at
its option, require such Lender to assign its interest in the Loan to Cahill,
Warnock Strategic Partners Fund, L.P. for a price equal to the then outstanding
principal amount thereof plus accrued and unpaid interest, fees and costs and
expenses due such Lender under the Loan Documents, which principal, interest,
fees and costs and expenses will be paid on the date of such assignment. In the
event that Cahill, Warnock Strategic Partners Fund, L.P. elects to require any
Lender to assign its interest to Cahill, Warnock Strategic Partners Fund, L.P.,
will so notify such Lender in writing within thirty (30) days following such
Lender's denial, and such Lender will assign its interest to Cahill, Warnock
Strategic Partners Fund, L.P no later than five (5) days following receipt of
such notice.

      8.12.       Dissemination of Information.

         The Agent will provide the Lenders with any information received by
the Agent from Borrower which is required to be provided to the Agent or to the
Lenders hereunder; provided, however, that the Agent shall not be liable to any
one or more the Lenders for any failure to do so, except to the extent that
such failure is attributable to the Agent's gross negligence or willful
misconduct.

Obligations remain outstanding, at a rental of $1.00 for such entire term, the
right to the use of all premises or places of business which Borrower now or
hereafter may have and where any Collateral may be located; provided that Agent
agrees not to exercise such right unless and until an Event of Default occurs
and is continuing and Agent determines to exercise its rights against
Collateral hereunder.

      10.11. Instruments Evidencing Accounts. If any Accounts are at any time
evidenced by promissory notes, trade acceptances or other instruments for the
payment of money, Borrowers will immediately deliver the same to Agent
appropriately endorsed to Lender's order and, regardless of the form of such
endorsement, each Borrower hereby waives presentment, demand, notice of
dishonor, protest, notice of protest and all other notices with respect
thereto.

      10.12. Continuing Security Interest. In the event of the sale, exchange
or disposition of any of the Collateral or any interest therein (and no such
sale, exchange or other disposition is hereby authorized or consented to,
except as permitted and provided in Section 9.1), Agent's and/or Lenders'
security interest shall nevertheless continue in such Collateral (including
without limitation all proceeds, cash and non-cash) notwithstanding such sale,
exchange or other disposition; all of said proceeds shall remain Collateral
hereunder and shall be transferred and paid over to Agent immediately, and
shall be applied at Agent's option to the payment of Obligations; and Agent's
receipt of any such Proceeds shall not be deemed or construed to be an
authorization of or consent to any such sale, exchange or other disposition.

      10.13. No Lender Liability. Notwithstanding anything to the contrary set
forth herein, neither Lenders nor Agent shall have any obligation or liability
under any Accounts, Leases or other Collateral arising out of this Agreement or
Agent's or Lenders' exercise of its rights and remedies or Borrower's
performance of its obligations hereunder, nor shall Agent or Lenders have any
obligation to make any inquiry as to the nature or sufficiency of any payment
received by it, or to file any claim or take any action to enforce the payment
or performance of any portion of the Collateral. Beyond the safe custody
thereof, Agent and/or Lenders shall have no duty as to any Collateral in it or
its nominee's possession or any income thereon, or as to the preservation of
rights against other parties or otherwise.


                                   SECTION 11

                               EVENTS OF DEFAULT

the following shall constitute an Event of Default:

amount when due on account of the Loan, which failure shall continue for a
period of three (3) days after notice thereof has been made by Agent to
Borrower;

         (b) failure by a Borrower to pay any other Obligation within five (5)
days of notice by Agent that such other Obligation is due;

         (d) loss, theft, damage, or destruction of any part of the Collateral;
provided, that Agent will not declare a default if the loss is insured against
in full or if substitute Collateral is pledged within thirty (30) days thereof;

         (e) the Collateral directly or indirectly becomes the subject matter
of any executable judgment (which is not covered by insurance) that could, in
the reasonable opinion of the Agent, based upon written advice from counsel
selected by the Agent, result in (i) impairment of, or loss of, the security
interests intended to be provided by this Agreement, or (ii) forfeiture of any
of the Collateral to the Federal Government, any state government or agency
thereof, or any foreign government which shall remain undischarged or unvacated
for a period in excess of thirty (30) days or execution shall at any time not
be effectively stayed;

<PAGE>   54



         (f) occurrence of any event of default as defined in any other

         (g) a Borrower's liquidation, termination, dissolution or cessation of
a substantial part of its current business;

         (h) commencement by a Borrower of a voluntary proceeding seeking
relief with respect to itself or its debts under any bankruptcy, insolvency or
other similar law, or seeking appointment of a trustee, receiver, liquidator or
other similar official for it or any substantial part of its assets; or its
consent to any of the foregoing in an involuntary proceeding against it; or a
Borrower shall generally not be paying its debts as they become due or admit in
writing its inability to do so; or an assignment for the benefit of, or the
offering to or entering into by a Borrower of any composition, extension,
reorganization or other Agreement or arrangement with, its creditors;

         (i) commencement of an involuntary proceeding against a Borrower
seeking relief with respect to it or its debts under any bankruptcy, insolvency

or other similar official for it or any substantial part of its assets, which
proceeding is not dismissed or stayed within sixty (60) days;

         (j) service upon Agent of a writ of levy or attachment or naming Agent
as trustee for Borrower, or of any other similar process or attachment in an
amount of $100,000 or more and if less than $100,000, if such levy, attachment
or process is not discharged in 30 days;

         (k) entry of any executable judgment(s) against Borrowers in an
aggregate amount greater than $100,000 which is not covered by insurance (and
for this purpose a judgment shall be deemed "covered by insurance" only if the
insurance company has formally advised Borrowers that the judgment in its
entirety is covered by insurance and no action is being taken to execute such
judgment against a Borrower's assets) and shall remain undischarged or
unvacated for a period in excess of thirty (30) days or execution shall at any
time not be effectively stayed;

         (l) attachment of any Lien in excess of $100,000 (other than a

business;

in excess of $100,000, unless contracted in good faith; or


                                       48

<PAGE>   55



         (o) there shall occur and be continuing any Reportable Event which
constitutes grounds for termination of or for appointment by a United States
district court of a trustee to administer any Plan; the PBGC shall institute
proceedings to terminate or to appoint a trustee to administer any Plan; a
United States district court shall appoint a trustee to administer any Plan; or
any Plan shall be terminated in circumstances giving rise to liabilities having
a material adverse effect on a Borrower's financial condition.

      Each Borrower acknowledges and agrees that each and every Event of
Default described above shall be of equal weight and significance, and equally
and fully shall allow Agent to exercise its rights and remedies hereunder. Each
Borrower acknowledges and agrees that each such Event of Default has been a
material inducement for Agent and/Lenders or to enter into its Agreement and
that Agent and/or Lenders would be irreparably harmed if Agent and/or Lenders,
in any way, were unable to exercise their rights and remedies on the basis that
certain Event of Default (for example, Events of Default not relating to
payment) were of less weight or significance than certain other Events of
Default (for example, Events of Default relating to payment).


                                   SECTION 12

                AGENT'S RIGHTS AND REMEDIES UPON THE OCCURRENCE
                             OF AN EVENT OF DEFAULT

      Following the occurrence and during the continuance of an Event of
Default, Agent may, at its option:

      12.1. Remedies. Agent may declare any and all of the Obligations to be
immediately due and payable; and, in addition to that right, and in addition to
exercising all other rights or remedies, Agent may proceed to exercise with
respect to the Collateral all rights, options and remedies of a secured party
upon default as provided for under the UCC.

      12.2. Exercise of Remedies. Agent may by notice to Borrower terminate the
commitment to make the Loans under Section 2 and/or accelerate the payment of
all Obligations (provided that no such notice shall be required if the Event of
Default is under Sections 11.1(i) or 11.1(j)); Agent may proceed to enforce
payment of any of the Obligations and shall have and may exercise any and all
rights under the Uniform Commercial Code or which are afforded to Agent herein
or otherwise; and all Obligations (including without limitation principal,
accrued interest, amounts payable under Section 13.1 or upon entry of any
judgment) shall bear interest payable on demand at the rate per annum five
percent (5%) in excess of the applicable rate of interest provided in Section 2
(the "Default Rate").

      12.3. Disposition of Collateral.  Agent may sell, lease or otherwise
dispose of and deliver any or all Collateral at public or private sale, for
cash, upon credit or otherwise, at such

                                       49

<PAGE>   56



prices and upon such terms as Agent deems advisable in its sole discretion. Any
requirements of reasonable notice shall be met if such notice is mailed postage
prepaid to Borrowers at its address set forth herein at least ten (10) business
days before the time of sale or other disposition. Agent or a Lender may be the
purchaser at any such sale, if it is public, and in such event Agent and/or
Lender shall have all rights of a good faith, bona fide purchaser for value
from a secured party after default. The proceeds of any sale may be applied (in
whatever order and manner Agent elects in its sole discretion) to all costs and
expenses of sale (including without limitation reasonable attorneys' fees and
disbursements) and to the payment of Obligations, and any remaining proceeds
shall be applied in accordance with Article 9, Part 5, of the UCC. Borrower
shall remain liable to Agent for any deficiency.

      12.4. Cumulative Remedies. The rights and remedies of the Agent and/or
Lender shall be deemed to be cumulative, and any exercise of any right or
remedy shall not be deemed to be an election of that right or remedy to the
exclusion of any other right or remedy.

      12.5. Waivers. Each Borrower acknowledges that this Agreement involves
the grant of multiple security interests, and such Borrower hereby waives, to
the extent permitted by applicable law, (i) any requirement of marshaling
assets or proceeding against persons or assets in any particular order, and
(ii) any and all notices of every kind and description that may be required to
be given by any statute or rule of law and any defense of any kind based on any
such notice, except any notices required under the Note.


                                   SECTION 13


                             INDEMNIFICATION, ETC.

      13.1. Environmental Indemnity. Each Borrower shall indemnify, defend, and
hold harmless Agent, each Lender, its Affiliates, and their respective
directors, officers, shareholders, partners, employees, consultants and agents
(herein individually called an "Indemnified Party," and collectively called
"Indemnified Parties") from and against, and shall reimburse and pay
Indemnified Parties with respect to, any and all claims, demands, liabilities,
losses, damages (including without limitation actual, consequential, exemplary
and punitive damages), causes of action, judgments, penalties, fees, costs and
expenses (including without limitation attorneys' fees, court costs and legal
expenses and consultant's and expert's fees and expenses) of any and every kind
or character, known or unknown, fixed or contingent, that may be imposed upon,
asserted against, or incurred or paid by or on behalf of any Indemnified Party
on account of, in connection with, or arising out of (a) the breach of any
representation or warranty of a Borrower relating to Environmental Laws or
Hazardous Materials, or (b) the failure of a Borrower to perform any agreement,
covenant or obligation required to be performed by a Borrower relating to
Environmental Laws or Hazardous Materials, (c) any violation of or failure to
comply with any Environmental Law now existing or hereafter occurring, (d) the
removal of Hazardous

                                       50

<PAGE>   57



Materials from a Borrower's properties (or if removal is prohibited by law, the
taking of whatever action is required by law), (e) any act, omission, event or
circumstance existing or occurring or resulting from or in connection with the
ownership, construction, occupancy, operation, use or maintenance of the
properties, regardless of whether the act, omission, event or circumstance
constituted a violation of or failure to comply with any Environmental Law at
the time of its existence or occurrence, and (f) any and all claims or
proceedings (whether brought by private party or governmental agency) for
bodily injury, property damage, abatement or remediation, environmental damage,
or impairment or any other injury or damage resulting from or relating to any
Hazardous Material located upon or migrating into, on, from or through the
properties (whether or not any or all of the foregoing was caused by a
Borrower, a prior owner of the properties, an operator or prior operator of the
properties, their respective tenants or subtenants, or any third party and
whether or not the alleged liability is attributable to the handling, storage,
use, treatment, processing, distribution, manufacture, generation, discharge,
transportation or disposal of such Hazardous Material or the mere presence of
such Hazardous Material on the properties). Without limiting the generality of
the foregoing, it is the intention of each Borrower and each Borrower agrees
that the foregoing indemnities shall apply to each Indemnified Party with
respect to claims, demands, liabilities, losses, damages (including without
limitation actual, consequential, exemplary and punitive damages), causes of
action, judgments, penalties, fees, costs, court costs and legal expenses and
consultant's and expert's fees and expenses, of any kind or character, known or
unknown, fixed or contingent, that in whole or in part are caused by or arise
out of the negligence of such Indemnified Party; however, such indemnities
shall not apply to any Indemnified Party to the extent the subject of the
indemnification is caused by or arises out of the gross negligence or willful
misconduct of such Indemnified Party. The foregoing indemnities shall be
perpetual and shall survive the payment or satisfaction of the Loans and the
release, foreclosure or other termination of the Loan Document. Any amount to
be paid hereunder by Borrower to Agent and/or Lenders or for which Borrower has
indemnified an Indemnified Party shall be a demand obligation owing by Borrower
to Agent and/or Lenders and shall bear interest at the Default Rate until paid,
and shall constitute a part of the obligations of Borrower under this Agreement
and shall be indebtedness evidenced by this Agreement and secured by the Loan
Documents.

      13.2.                GENERAL INDEMNITY.  EACH BORROWER AGREES TO
INDEMNIFY AGENT AND/OR LENDERS UPON DEMAND, FROM AND AGAINST ANY AND ALL
LIABILITIES, OBLIGATIONS, PENALTIES, ACTIONS, JUDGMENTS, SUITS, SETTLEMENTS,
COSTS, EXPENSES OR DISBURSEMENTS (INCLUDING REASONABLE FEES OF ATTORNEYS,
ACCOUNTANTS, EXPERTS AND ADVISORS) OF ANY KIND OR NATURE WHATSOEVER (IN THIS
SECTION COLLECTIVELY CALLED "LIABILITIES AND COSTS") WHICH TO ANY EXTENT (IN
WHOLE OR IN PART) MAY BE IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST LENDER
GROWING OUT OF, RESULTING FROM OR IN ANY OTHER WAY ASSOCIATED WITH ANY OF THE
COLLATERAL, THE LOAN DOCUMENTS, OR THE TRANSACTIONS AND EVENTS (INCLUDING THE
ENFORCEMENT OR DEFENSE THEREOF) AT ANY TIME ASSOCIATED THEREWITH OR
CONTEMPLATED THEREIN. THE FOREGOING

                                       51

<PAGE>   58



INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN
ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR
OMISSION OF ANY KIND BY AGENT AND/OR LENDER PROVIDED ONLY THAT A LENDER SHALL
NOT BE ENTITLED UNDER THIS SECTION TO RECEIVE INDEMNIFICATION FOR THAT PORTION,
IF ANY, OF ANY LIABILITIES AND COSTS WHICH IS PROXIMATELY CAUSED BY ITS OWN
INDIVIDUAL GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, AS DETERMINED IN A FINAL
JUDGMENT. IF ANY PERSON (INCLUDING A BORROWER OR ANY OF ITS AFFILIATES) EVER
ALLEGES SUCH GROSS NEGLIGENCE OR WILLFUL MISCONDUCT BY A LENDER OR THE AGENT,
THE INDEMNIFICATION PROVIDED FOR IN THIS SECTION SHALL NONETHELESS BE PAID UPON
DEMAND, SUBJECT TO LATER ADJUSTMENT OR REIMBURSEMENT, UNTIL SUCH TIME AS A
COURT OF COMPETENT JURISDICTION ENTERS A FINAL JUDGMENT AS TO THE EXTENT AND
EFFECT OF THE ALLEGED GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. ANY AMOUNT TO BE
PAID HEREUNDER BY BORROWER TO AGENT AND/OR LENDERS, OR FOR WHICH BORROWER HAS
INDEMNIFIED AN INDEMNIFIED PARTY, SHALL BE A DEMAND OBLIGATION OWING BY
BORROWER TO AGENT AND/OR LENDER AND SHALL BEAR INTEREST AT THE DEFAULT RATE
UNTIL PAID, AND SHALL CONSTITUTE A PART OF THE OBLIGATIONS OF BORROWER UNDER
THIS AGREEMENT AND SHALL BE INDEBTEDNESS EVIDENCED BY THIS AGREEMENT AND
SECURED BY THE LOAN DOCUMENTS. AS USED IN THIS SECTION THE TERM "LENDER" SHALL
REFER NOT ONLY TO THE PERSON DESIGNATED AS SUCH IN THIS SECTION BUT ALSO TO
EACH DIRECTOR, OFFICER, PARTNER, AGENT, ATTORNEY, EMPLOYEE, REPRESENTATIVE AND
AFFILIATE OF SUCH PERSON.

      13.3. Exculpation. In the absence of willful misconduct taken or omitted
in bad faith, or gross negligence, neither a Lender, Agent nor any
attorney-in-fact pursuant to Section 10.__ shall be liable to a Borrower or any
other Person for any act or omission, any mistake of fact or any error of
judgment in exercising any right or remedy granted herein.

      13.4. Collateral Secures Indemnification. Agent shall be entitled to
retain Collateral or require substitution therefor to the extent required to
assure Agents of satisfaction of Borrower's Obligations under this Section 13.

         14.2. No Waiver. No failure to exercise and no delay in exercising, on
the part of Agent and/or a Lender, any right or remedy hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise thereof preclude
any other or further exercise thereof or the exercise of any other right or
remedy. Waiver by Agent and/or a Lender of any right or remedy on any one
occasion shall not be construed as a bar to or waiver thereof or of any other
right or remedy on any future occasion. Without limiting the generality of the
foregoing, the Borrowers expressly agree that no failure by a Agent and/or
Lenders to detect or to communicate with a Borrower or take action in response
to any failure by a Borrower to perform or observe any Obligation shall operate
as a waiver of any right or remedy of Agent and/or Lenders. Any waivers by
Agent and/or Lenders must be in writing. Agent's and/or Lender's rights and
remedies hereunder, under any Agreement or instrument supplemental hereto or
under any other Agreement or instrument shall be cumulative, may be exercised
singly or concurrently and are not exclusive of any rights or remedies provided
by law.

         14.3. Assignment. This Agreement shall be binding upon and shall inure
to the benefit of each Borrower, Agents and Lenders and their respective
successors and assigns; provided that Borrowers may not assign or transfer any
rights or Obligations hereunder without Agent's prior written consent.

         14.4. Headings. The headings contained herein are for convenience only
and shall not affect the construction hereof. If one or more provisions of this
Agreement (or the application thereof) shall be invalid, illegal or
unenforceable in any respect in any jurisdiction, the same shall not, to the
fullest extent permitted by applicable law, invalidate or render illegal or
unenforceable such provision (or its application) in any other jurisdiction or
any other provision of this

                                       54

<PAGE>   61



Agreement (or its application). This Agreement is the entire Agreement of the
parties with respect to the subject matter hereof and supersedes any prior
written or verbal communications or instruments relating thereof.

         14.5. Term. This Agreement shall continue in full force and effect so
long as any of the Obligations remains outstanding or has not been fully and
finally paid, performed or satisfied. All agreements, representations,
warranties and covenants made herein shall survive delivery of this Agreement
and the Note.

         14.6. Waiver of Remedies. Each Borrower acknowledges that the
transactions contemplated hereby are commercial transactions and waives, to the
fullest extent it may do so under applicable law, such rights as it may have or
hereafter have to notices and/or hearings under applicable federal or state
laws relating to exercise of any of Agent's and/or Lenders' rights, including
without limitation the right to deprive a Borrower of or affect its use,
possession or enjoyment of property prior to rendition of a final judgment
against Borrower.

         14.7. Further Assurances. Each Borrower shall execute and deliver to
Agent such further assurances and take such other further actions as Agent may
from time to time request to further the intent and purpose of this Agreement
and to maintain and protect the rights and remedies intended in favor of Agent
and/or Lenders under this Agreement. Borrowers shall execute and deliver to
Agent any financing statement or other notice document requested, or procure
any other document requested, and record such financing statements or other
notice documents to perfect the Liens, and the first priority of the Liens,
created under this Agreement. If the Collateral is of a type as to which it is
necessary or desirable for Agent to take possession of the Collateral in order
to perfect, or maintain the priority of, Agent's Liens, then upon Agent's
request, such Borrower shall deliver such Collateral to Agent.

         14.8. Counterparts. This Agreement may be signed in any number of
counterparts with the same effect as if the signature thereto and hereto were
upon the same instrument.

         14.9. Fees and Expenses. Borrower shall pay to Agent all reasonable
costs, filing fees, expenses, losses, claims, damages, liabilities, penalties,

                                       55

<PAGE>   62



section to the contrary, the parties hereto agree that each party shall pay its
own respective fees and disbursements for legal counsel incurred in connection
with the Loan Documents.

         14.10. Consent of all Lenders. Notwithstanding anything to the
contrary contained herein, no amendment, modification, change or waiver shall
be effective without the consent of all of the Lenders to:

                  (a) extend the maturity of the principal of, or interest on,
any Note or of any of the other Obligations;

                  (b) reduce the principal amount of any Note or of any of the
other Obligations, the rate of interest thereon due to the Lenders, except as
expressly permitted herein or therein;

                  (c) change the aggregate Commitments;

                  (d) change the date of payment of principal of, or interest
on, any Note or of any of the other Obligations;

                  (e) change the method of calculation utilized in connection 
with the computation of interest;

                  (f) change the manner of pro rata application by the Agent of
payments made by the Borrowers, or any other payments required hereunder or
under the other Loan Documents;

                  (g) modify this Section, Section 8.8 or Section 8.12;

                  (h) release or agree to subordinate any material portion of
any Collateral or Financing Document (except to the extent provided herein or
therein); or

                  (i) waive the performance, observance or compliance with or
amend and financial covenants.

Additionally, no change may be made to the amount of a Lender's Commitment
without the prior written consent of that Lender.

         14.11 Usury Laws. It is the intention of the parties hereto to comply
with all applicable usury laws; accordingly, it is agreed that notwithstanding
any provisions to the contrary in this Agreement or any other Loan Documents,
in no event shall such Loan Documents require the payment or permit the
collection of interest (which term, for purposes hereof, shall include any
amount which, under applicable law, is deemed to be interest, whether or not
such amount is characterized by the parties as interest) in excess of the
maximum amount permitted by such laws. If any excess of interest is
unintentionally contracted for, charged or received under this Agreement or
under the terms of any other Loan Documents, or in the event the maturity of
the

                                       56

<PAGE>   63



indebtedness evidenced by the Notes is accelerated in whole or in part, or in
the event that all or part of the principal or interest of the Notes shall be
prepaid, so that the amount of interest contracted for, charged or received
under this Agreement or under any of the other Loan Documents, on the amount of
principal actually outstanding from time to time under this Agreement shall
exceed the maximum amount of interest permitted by the applicable usury laws,
then in any such event (i) the provisions of this paragraph shall govern and
control, (ii) neither Borrowers nor any other person or entity now or hereafter
liable for the payment thereof, shall be obligated to pay the amount of such
interest to the extent that it is in excess of the maximum amount of interest
permitted by such applicable usury laws, (iii) any such excess which may have
been collected shall be either applied as a credit against the then unpaid
principal amount thereof or refunded to Borrowers at Lender's option, and (iv)
the effective rate of interest shall be automatically reduced to the maximum
lawful rate of interest allowed under the applicable usury laws as now or
hereafter construed by the courts having jurisdiction thereof. It is further
agreed that without limitation of the foregoing, all calculations of the rate
of interest contracted for, charged or received under the Notes or under such
other Loan Documents which are made for the purpose of determining whether such
rate exceeds the maximum lawful rate of interest, shall be made, to the extent
permitted by applicable laws, by amortizing, prorating, allocating and
spreading in equal parts during the period of the full stated term of the Loans
evidenced thereby, all interest at any time contracted for, charged or received
from Borrowers or otherwise by Lenders in connection with such Loans.

                         REGISTRATION RIGHTS AGREEMENT


         This Registration Rights Agreement (the "Agreement") is made by and
between the undersigned (the "Shareholder") and ENVIRONMENTAL SAFEGUARDS, INC.,
a Texas corporation (the "Company").


                              W I T N E S S E T H:

         WHEREAS, pursuant to that certain Subscription Agreement (the
"Subscription Agreement") the Shareholder has purchased __________ shares (the
"Shares") of common stock of the Company, par value $.001 per share (the
"Common Stock") in the Offering of Shares of Common Stock (the "Offering") made
by the Company as described in the Confidential Private Placement Memorandum
dated September 18, 1996 (the "Memorandum");

         NOW THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

         1. The Registration. Commencing six months after the Termination Date
(as defined in the Memorandum) of the Offering and continuing for a period of
two years from the Termination Date, subject to the Shareholder and the
purchasers in the Offering holding, at the time of exercise of their rights,
Shares of Common Stock which represent in the aggregate a minimum of 10,000
shares (the "Registration Shares") (such number as determined without
adjustment for stock dividends, reclassifications, splits and reverse splits
occurring after the date of the closing of the Offering), upon the written
request of the Shareholder and such purchasers in the Offering requesting that
the Company effect the registration under the Securities Act of 1933, as
amended (the "Securities Act") of all or a specified portion of the
Registration Shares, the Company will use its best efforts to file a
registration statement (the "Registration Statement") under the Securities Act
with the Securities and Exchange Commission (the "Commission"). The Company
shall promptly give written notice of such requested registration to all
holders of record of shares of Common Stock, which were purchased or issued in
connection with the Offering. The Registration Statement will include the
Registration Shares, all other shares for which written notice was given by the
Company which are requested to be included by the holders thereof by written
notice to the Company within thirty (30) days of the giving of written notice
by the Company and may include shares of Common Stock other than the foregoing,
either for the Company's account or for the account of other selling
shareholders. The Company will use reasonable efforts to cause the Registration
Statement to become effective and to keep the Registration Statement current
for a period of two years after the Termination Date of the Offering. The
Company shall not be obligated to effect more than one registration on behalf
of Shareholder and purchasers in the Offering under this section.
Notwithstanding the foregoing, if the Company is engaged in negotiations in
respect of an acquisition or financing transaction and, in the good faith
judgment of the Board of Directors such transaction would be adversely affected
by the filing of the Registration Statement, the Company


<PAGE>   2



shall be entitled to postpone the filing of such registration statement until
such transaction would not be adversely affected by such filing but, in any
event, for a period not to exceed six months.


         2.       Registration Procedures.

                  (a)      In performing its obligations under Section 1 to
                           register the Shares, the Company will, subject to
                           the limitations provided herein, as expeditiously as
                           possible:

                            (i)  prepare and file with the Commission the
                                 Registration Statement and use its
                                 commercially reasonable best efforts to cause
                                 such registration to become and remain
                                 effective for the term specified herein;

                            (ii) prepare and file with the Commission such
                                 amendments and supplements to the Registration
                                 Statement and the Prospectus used in
                                 connection therewith as may be necessary to
                                 keep the Registration Statement effective in
                                 accordance with the terms of the Agreement and
                                 to comply with the provisions of the
                                 Securities Act with respect to the disposition
                                 of all shares covered by the Registration

                            (ii) furnish to the Shareholder one conformed copy
                                 of the Registration Statement and of each such
                                 amendment and supplement thereto (in each case
                                 including all exhibits), one copy of the
                                 Prospectus (including each preliminary
                                 prospectus and any summary prospectus) and any
                                 other Prospectus filed under Rule 424 under
                                 the Securities Act, and such other documents,
                                 as the Shareholder may reasonably request;

                            (iv) use its reasonable efforts to (a) register or
                                 qualify the Shares under such other securities
                                 or blue sky laws of such jurisdictions as the
                                 Shareholder shall reasonably request, (b) keep
                                 such registration or qualification in effect
                                 for so long as each of the Registration
                                 Statement remain in effect, and (c) take any
                                 other action which may be reasonably necessary
                                 or advisable to enable the Shareholder to
                                 consummate the disposition of the Shares in
                                 such jurisdictions, except that the Company
                                 shall not for any such purpose be required to
                                 qualify generally to do business as a foreign
                                 corporation in any jurisdiction wherein it
                                 would not but for the requirements of this
                                 subdivision (iv) be obligated to be so
                                 qualified, to consent to general service of
                                 process in any such jurisdiction, or to take

                                 such action which would impose unreasonable 
                                 expense on the Company;

                         (v)     furnish to the Shareholder a copy of an
                                 opinion of counsel for the Company rendered to

                                 covered in opinions of issuer's counsel

                                 public offerings of securities;

                         (vi)    notify the Shareholder at any time when a
                                 Prospectus relating to the Shares is required
                                 to be delivered under the Securities Act, upon
                                 discovery that, or upon the happening of any
                                 event as a result of which, the Prospectus
                                 included in the Registration Statement, as
                                 then in effect, includes an untrue statement

                                 necessary to make the statements therein not
                                 misleading in the light of the circumstances
                                 under which they were made, and prepare and
                                 furnish to the Shareholder one copy of a
                                 supplement to or an amendment of such
                                 Prospectus as may be necessary so that, as
                                 thereafter delivered to the purchasers of such
                                 securities, such Prospectus shall not include
                                 an untrue statement of a material fact or omit
                                 to state a material fact required to be stated
                                 therein or necessary to make the statements
                                 therein not misleading in the light of the
                                 circumstances under which they were made;

                        (vii)    otherwise use reasonable efforts to comply with
                                 all applicable rules and regulations of the 
                                 Commission;

                                 agent for the Common Stock from and after a
                                 date not later than the effective date of the

                                 a copy of such document to the Shareholder;

                         (xii)   cooperate with the Shareholder to facilitate

                                 diligence responsibility, and cause the
                                 Company's officers, directors and employees to

                      fees and disbursements of the Company's counsel,
                      independent certified public accountants, and other
                      persons retained by the Company (all such expenses being
                      herein called "Registration Expenses") will be borne by
                      the Company. The Shareholder shall be responsible for all
                      selling fees, expenses, discounts and commissions
                      relating to the Shares and for the fees and expenses of
                      counsel and other persons engaged by the Shareholder.

       3.      Obligations of Shareholder.

               (a)    The Shareholder agrees that it will offer and sell Shares
                      in compliance with all applicable state and federal
                      securities laws. Specifically, without limitation, the
                      Shareholder agrees as follows:

                      (i)     The Shareholder agrees not to use any prospectus
                              (as that term is defined under the Securities
                              Act) for the purpose of offering or selling the
                              Shares to the public except for the Prospectus,
                              as the same may be supplemented and amended from
                              time to time.

                      (ii)    Neither the Shareholder nor any affiliate of the
                              Shareholder shall engage in any practice which
                              would violate Rule 10b-6 promulgated under the
                              Securities Exchange Act of 1934 ("Exchange Act").

                      (iii)   Neither the Shareholder nor any affiliate of the
                              Shareholder shall solicit purchases of Common
                              Stock to facilitate the distribution of Shares in
                              violation of Rule 10b-2 promulgated under the
                              Exchange Act.

                      (iv)    Neither the Shareholder nor any affiliate of the
                              Shareholder shall effect any stabilizing
                              transactions to facilitate the offer and sale of
                              Shares to the public in violation of Rule 10b-7
                              promulgated under the Exchange Act.

               (b)    The Shareholder agrees to promptly notify the Company as
                      and when any Shares are sold and when the Shareholder
                      elects to terminate all further offers and sales of
                      Shares pursuant to the Registration Statement. The
                      Shareholder acknowledges that any Shares which have not
                      been sold within two years after the Termination Date of
                      the Offering or any earlier termination of the
                      distribution of the Shares will be removed from
                      registration by means of a post-effective amendment to
                      the Registration Statement.

               (c)    It shall be a condition precedent to the obligations of
                      the Company to take any action with respect to
                      registering the Shares that the Shareholder furnish the
                      Company in writing such information regarding the
                      Shareholder, the Shares and other securities of the
                      Company held by the Shareholder, and the distribution of
                      such Shares as the Company may from time to time
                      reasonably request in

                                      -5-

<PAGE>   6



                      writing. If the Shareholder refuses to provide the
                      Company with any of such information on the grounds that
                      it is not necessary to include such information in the
                      Registration Statement, the Company may exclude the
                      Shareholder's Shares from the Registration Statement if
                      the Company provides the Shareholder with an opinion of
                      counsel to the effect that such information must be
                      included in the Registration Statement and the
                      Shareholder thereafter continues to withhold such
                      information.

                              The Shareholder agrees that upon receipt of any
                      notice from the Company of the happening of any event of
                      the kind described in Section 2(a)(vi), the Shareholder
                      will forthwith discontinue the Shareholder's disposition
                      of Shares pursuant to the Registration Statement until
                      the Shareholder's receipt of the copies of the
                      supplemented or amended prospectus contemplated by
                      Section 2(a)(vi) and, if so directed by the Company, will
                      deliver to the Company (at the Company's expense) all
                      copies, other than permanent file copies then in such
                      Shareholder's possession, of the Prospectus current at
                      the time of receipt of such notice.

       4. Public Offering by the Company. Notwithstanding the registration
rights granted to the Shareholder under this Agreement, in the event the
Company files a registration statement for an underwritten public offering of
Common Stock (a "Company Offering") within two years of the Termination Date of
the Offering and while the Registration Statement covering the Registration
Shares is effective, then upon the request of the Company's underwriter in such
Company Offering, the Shareholder agrees to enter into an agreement pursuant to
which the Shareholder will be prohibited from transferring the Shares for such
period of time, not to exceed 90 days after completion of the Company Offering,
as the Company's underwriter may request. The Company may enter stop transfer
orders with its transfer agent in order to effect this prohibition. In the
event the Company makes a Company Offering and the Company's underwriter
imposes transfer restrictions on the sale of Shares, the period during which
the Registration Statement will be kept current shall not be extended beyond
the maximum two-year period from the Termination Date of the Offering as
provided in Section 1.

       5. Restrictions on Transfer. The Shareholder agrees that it will not
sell, exchange, pledge or otherwise transfer any Shares except in transactions
(i) made pursuant to the Registration Statement, or (ii) which are exempt from
all registration requirements of the Securities Act (or conducted pursuant to
Rule 144 thereunder) and all applicable state securities laws, and for which
the Company is provided with an opinion of counsel to the Shareholder and other
evidence as may be reasonably satisfactory to the Company to the effect that
such transfer will not be in violation of the Securities Act and all applicable
state securities laws.

       6. Indemnification.

                      by law, the Company will, and hereby does, indemnify and
                      hold harmless the Shareholder, its directors and
                      officers, each other natural person, corporation,
                      business trust, association, company, partnership, joint
                      venture and other entity (each, a "Person") who
                      participates as an underwriter in the offering or sale of
                      such securities and each other Person, if any, who
                      controls the Shareholder or any such underwriter within
                      the meaning of the Securities Act, against any losses,
                      claims, damages or liabilities, joint or several, to
                      which the Shareholder or any such director or officer or
                      underwriter or controlling Person may become subject
                      under the Securities Act or otherwise, insofar as such
                      losses, claims, damages or liabilities (or actions or
                      proceedings, whether commenced or threatened, in respect
                      thereof) arise out of or are based upon any untrue
                      statement or alleged untrue statement of any material
                      fact contained in any registration statement under which
                      such securities were registered under the Securities Act,

                      prospectus contained therein, or any amendment or
                      supplement thereto, or any omission or alleged omission
                      to state therein a material fact required to be stated
                      therein or necessary to make the statements therein not
                      misleading, and the Company will reimburse the
                      Shareholder and each such director, officer, underwriter
                      and controlling person for any legal or any other
                      expenses reasonably incurred by them in connection with
                      investigating or defending any such loss, claim,
                      liability, action or proceeding; provided that --------
                      the Company shall not be liable in any such case to the
                      extent that any such loss, claim, damage, liability (or
                      action or proceeding in respect thereof) or expense
                      arises out of or is based upon an untrue statement or
                      alleged untrue statement or omission or alleged omission
                      made in such registration statement, any such preliminary
                      prospectus, final prospectus, summary prospectus,
                      amendment or supplement in reliance upon written
                      information furnished to the Company by the Shareholder
                      expressly for use in the preparation thereof. Such
                      indemnity shall remain in full force and effect
                      regardless of any investigation made by or on behalf of
                      the Shareholder or any such director, officer,
                      underwriter or controlling person and shall survive the
                      transfer of Shares by the Shareholder.

               (b)    Indemnification by the Shareholder.  To the extent 
                      permitted by law, the Shareholder will, and hereby does,
                      indemnify and hold harmless (in the same manner and to
                      the same extent as set forth in subdivision (a) of this
                      Section 6) each underwriter, each Person who controls

                      Act, the Company, each director of the Company, each

                      or supplement thereto, if such statement or alleged

                      preceding subdivisions of this Section 6, such
                      indemnified party will, if a claim in respect thereof is
                      to be made against an indemnifying party, give written
                      notice to the latter of the commencement of such action,
                      provided that the failure of any indemnified party to
                      give notice as provided herein shall not relieve the
                      indemnifying party of its obligations under the preceding
                      subdivisions of this Section 6, except to the extent that
                      the indemnifying party is actually prejudiced by such
                      failure to give notice. In case any such action is
                      brought against an indemnified party, unless in such
                      indemnified party's reasonable judgment a conflict of
                      interest between such indemnified and indemnifying
                      parties actually exists in respect of such claim, the
                      indemnifying party shall be entitled to participate in
                      and to assume the defense thereof, jointly with any other
                      indemnifying party similarly notified to the extent that
                      it may wish, with counsel reasonably satisfactory to such
                      indemnified party, and after notice from the indemnifying
                      party to such indemnified party of its election to assume
                      the defense thereof, the indemnifying party shall not be
                      liable to such indemnified party for any legal or other
                      expenses subsequently incurred by the latter in
                      connection with the defense thereof other than reasonable
                      costs of investigation. No indemnifying party shall,
                      without the consent of the indemnified party, consent to
                      entry of any judgment or enter into any settlement which
                      does not include as an unconditional term thereof the
                      giving by the claimant or plaintiff to such indemnified
                      party of a release from all liability in respect to such
                      claim or litigation.

               (d)    Other Indemnification. Indemnification similar to that
                      specified in the preceding subdivisions of this Section 6
                      (with appropriate modifications) shall be given by the
                      Company and the Shareholder with respect to any required
                      registration or other qualification of securities under
                      any Federal or state law or regulation of any
                      governmental authority other than the Securities Act.

               (e)    Indemnification Payments. The indemnification required by
                      this Section 6 shall be made by periodic payments of the
                      amount thereof during the course of the investigation or
                      defense, as and when bills are received or expense, loss,
                      damage or liability is incurred.

                         REGISTRATION RIGHTS AGREEMENT

         This Registration Rights Agreement (this "Agreement"), dated as of
December 17, 1997, is by and between Environmental Safeguards, Inc., a Nevada
corporation ("Company"), and ________________________ (the "Holder").

                               W I T N E S E T H:

         WHEREAS, the Company has entered into a Purchase Agreement dated
December 17, 1997 (the "Purchase Agreement"), pursuant to which it has offered
and sold shares of its Series B Convertible Preferred Stock (the "Preferred
Stock") to certain participants thereto; and

         WHEREAS, the Company has sold shares of its Preferred Stock to the
Holder pursuant to the Purchase Agreement; and

         WHEREAS, the shares of Preferred Stock purchased by Holder are
convertible into shares of the Company's common stock, $0.001 par value per
share ("Common Stock"); and

         WHEREAS, in connection with Holder's purchase of the Preferred Stock,
the Company agreed to grant certain registration rights in respect of the
shares of Common Stock underlying the Preferred Stock (the "Shares").

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein, and other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the parties hereto
agree as follows:

                                  ARTICLE ONE
                              REGISTRATION RIGHTS

         Section 1.1 Registration Rights Available. The Company agrees to
provide Holder and its transferees or distributees (collectively the "Holders")
with the following registration rights with respect to the Shares and any other
securities issued or issuable at any time or from time to time in respect of
the Shares upon a stock split, stock dividend, recapitalization or other
similar event involving the Company (collectively, the "Registered Shares") (a)
two rights to demand registration in a secondary offering by means of shelf
registration under Rule 415 of the Securities Act of 1933, as amended (the
"Act"), and (b) "piggyback" registration in a firm commitment underwritten
offering of Company securities, all subject to the rights and limitations of
the provisions of this Agreement (the rights to two demand and unlimited
piggyback registrations granted hereunder are referred to herein as
"Registration Rights").

         Section 1.2  Demand Registration.

         (a) Subject to the restrictions of Section 1.2(b) below, upon the
written request of at least a majority of the Holders of the Preferred Stock
requesting that the Company effect a registration under the Act and specifying
the intended method of distribution thereof, the Company

                                       

<PAGE>   2



shall promptly use its best efforts to file with the Securities and Exchange
Commission (the "Commission") and cause to become effective as soon as
practicable thereafter, a Registration Statement on an appropriate form
relating to the offer and sale of the Registered Shares by the Holders. The
Company shall promptly give written notice of such requested registration to
all Holders of record of shares of Preferred Stock which were purchased in
connection with the Purchase Agreement. The Registration Statement will include
the Registered Shares, all other shares for which written notice was given by
the Company which are requested to be included by the Holders thereof by
written notice to the Company within 15 days of the giving of written notice by
the Company and may include shares of common stock other than the foregoing,
either for the Company's account or for the account of other selling
shareholders. The Company shall not be obligated to effect more than two
registrations on behalf of the Holders under this Section 1.2.

         (b) The Company shall not be required to file any registration
statement pursuant to Section 1.1(a): (i) when the Company is engaged in
discussions with an underwriter concerning a contemplated underwritten public
offering of its securities and the managing underwriter thereof has advised
Holders in writing that such filing would have a material adverse effect on the
contemplated offering; (ii) if the Company is engaged in negotiations in
respect of an acquisition or financing transaction and, in the good faith
judgment of the Board of Directors such transaction would be adversely affected
by the filing of the Registration Statement, provided clause (i) and (ii) shall
not delay the Company's obligations under this Section beyond 90 days after
completion of the contemplated offering or financing or notice of cancellation
of such contemplated offering or financing; or (iii) if the Company is in the
possession of material nonpublic information the disclosure of which, in the
good faith judgment of the Company's board of directors, would materially
adversely affect or materially interfere with its business; provided, however,
that if the Company's obligation to file a registration statement under this
Section is tolled by reason of one of the preceding clauses (i) - (iii) and a
registration request is made hereunder during such time, the Company shall
promptly notify Holder when the Company is able to file a registration
statement without conflicting with clauses (i) - (iii) above.

         Section 1.3 Piggyback Registration. With respect to Holders rights to
piggyback registration in a firm commitment underwriting of the Company
securities pursuant to Section 1.1 (b), the parties agree as follows:

         (a) Pursuant to Section 1.1(b), the Company will (i) promptly give to
Holders written notice of any registration relating to a firm commitment public
offering of the Company's securities; and (ii) include in such registration,
and in the underwriting involved therein, all the Registered Shares specified
in Holders written request delivered in accordance with Section 6.1 herein
within 15 days after the date of such written notice from the Company.

         (b) The right of the Holders to registration pursuant to Section
1.1(b) shall be conditioned upon Holders participation in such underwriting,
and the inclusion of the Registered Shares in the underwriting shall be limited
to the extent provided herein. The Holders proposing to distribute its
securities through such underwriting shall enter into an underwriting agreement

                                       2

<PAGE>   3


in customary form with the managing underwriter selected for such underwriting
by the Company. Notwithstanding any other provision of this Agreement, if the
managing underwriter determines that marketing factors require a limitation of
the number of shares to be underwritten, the managing underwriter may limit some
or all of the Registered Shares that may be included in the registration and
underwriting provided, however, the Holders shall have priority rights to
piggyback registration over any and all other persons. If Holder disapproves of
the terms of any such underwriting, it may elect to withdraw therefrom by
written notice to the Company and the managing underwriter, delivered not less
than seven days before the effective date. Any Registered Shares excluded or
withdrawn from such underwriting shall be withdrawn from such registration, and
shall not be transferred in a public distribution prior to 90 days after the
effective date of the registration statement relating thereto, or such other
shorter period of time as the underwriters may require.

         Section 1.4 Exception to Registration. The Company shall not be
required to effect a registration under this Article One if (i) in the written
opinion of counsel for the Company, which counsel and the opinion so rendered
shall be reasonably acceptable to Holders, such Holders may sell without
registration under the Act all Registered Shares which it requested
registration under the provisions of the Act and in the manner and in the
quantity in which the Registered Shares were proposed to be sold, or (ii) the
Company shall have obtained from the Commission a "no-action" letter to that
effect.

                                  ARTICLE TWO
                            REGISTRATION PROCEDURES

         Section 2.1 Registration Obligations. In performing its obligations
under Article One to register the Registered Shares, Company will, subject to
the limitations provided herein, as expeditiously as possible:

       (a) prepare and file with the Commission the Registration Statement and
use its best efforts to cause such registration to become and remain effective
for the term specified herein;

       (b) prepare and file with the Commission such amendments and supplements
to the Registration Statement and the Prospectus used in connection therewith
as may be necessary to keep the Registration Statement effective in accordance
with the terms of this Agreement and to comply with the provisions of the Act
with respect to the disposition of all Registered Shares covered by the
Registration Statement;

       (c) furnish to the Holder one conformed copy of the Registration
Statement and of each such amendment and supplement thereto (in each case
including all exhibits), one copy of the Prospectus (including each preliminary
prospectus and any summary prospectus) and any other Prospectus filed under
Rule 424 under the Act, and such other documents, as the Holder may reasonably
request;


                                       3

<PAGE>   4

       (d) use its best efforts to (i) register or qualify the Registered
Shares under such other securities or blue sky laws of such jurisdictions as
the Holder shall reasonably request, (ii) keep such

registration or qualification in effect for so long as the Registration
Statement remains in effect, and (iii) take any other action which may be
reasonably necessary or advisable to enable the Holder to consummate the
disposition of the Registered Shares in such jurisdictions, except that the
Company shall not for any such purpose be required to qualify generally to do
business as a foreign corporation in any jurisdiction wherein it would not but
for the requirements of this Section 2.1(d) be obligated to be so qualified, to
consent to general service of process in any such jurisdiction, or to take any
such action which would impose unreasonable expense on the Company;

       (e) notify the Holders at any time when a Prospectus relating to the
Shares is required to be delivered under the Act, upon discovery that, or upon
the happening of any event as a result of which, the Prospectus included in the
Registration Statement, as then in effect, includes an untrue statement of a
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein not misleading in the light of the
circumstances under which they were made, and prepare and furnish to the
Holders one copy of a supplement to or an amendment of such Prospectus as may
be necessary so that, as thereafter delivered to the purchasers of such
securities, such Prospectus shall not include an untrue statement of a material
fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in the light of the
circumstances under which they were made;

       (f) provide and cause to be maintained a transfer agent for the Common
Stock from and after a date not later than the effective date of the
Registration Statement;

       (g) properly notify any securities exchange on which any of the
Company's Common Stock is listed of the registration of any of the Registered
Shares, and use its best efforts to satisfy all prerequisites and regulations
of any such exchange relating to the trading of such Registered Shares on such
exchange; and

       (h) make available for inspection by the Holders, and any one attorney,
accountant or other agent retained by the Holders of Registered Shares, as a
group, (the "Inspector"), all financial and other records, pertinent corporate
documents and properties of the Company (collectively, the "Records"), as shall
be reasonably necessary to enable them to exercise their due diligence
responsibility, and cause the Company's officers, directors and employees to
supply all information reasonably requested by any such Inspector in connection
with such registration statement; provided that records which the Company
determines, in good faith, to be confidential and which it notifies the
Inspector are confidential shall not be disclosed by the Inspector unless (i)
the disclosure of such Records is necessary to avoid or correct a misstatement
or omission in the Registration Statement or (ii) the release of such Records
is ordered pursuant to a subpoena or other order from a court of competent
jurisdiction; provided, further, the Holders agree that they will, upon
learning that disclosure of such Records is sought in a court of competent
jurisdiction, give notice to the Company and allow the Company, at its expense,
to undertake appropriate action and to prevent disclosure of the Records deemed
confidential.


                                       4

<PAGE>   5



       Section 2.2 Registration Obligations of Holder. As a condition to the
Company performing its obligations under Article One to register the Registered
Shares, the Holder will, as expeditiously as possible:

       (a) furnish the Company in writing such information regarding the
Holder, the Registered Shares and other securities of the Company held by the
Holder, and the distribution of such Registered Shares as the Company may from
time to time reasonably request in writing. If the Holder refuses to provide
the Company with any of such information on the grounds that it is not
necessary to include such information in the Registration Statement, the
Company may exclude the Holder's Registered Shares from the Registration
Statement if the Company provides the Holder with an opinion of counsel to the
effect that such information must be included in the Registration Statement and
the Holder thereafter continues to withhold such information.

       (b) agree to promptly notify the Company as and when any Registered
Shares are sold and when the Holder elects to terminate all further offers and
sales of Shares pursuant to the Registration Statement.

       (c) upon receipt of any notice from the Company of the happening of any
event of the kind described in Section 2.1(e), the Holder will forthwith
discontinue the Holder's disposition of the Registered Shares pursuant to the
Registration Statement until the Holder's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 2.1(e) and, if so
directed by the Company, will deliver to the Company (at the Company's expense)
all copies, other than permanent file copies then in such Holder's possession,
of the current Prospectus at the time of receipt of such notice.

       Section 2.3 Expenses. All expenses incident to the Company's performance
of its obligations under this Agreement, including without limitation, all
registration and filing fees, fees and expenses of compliance with securities
and Blue Sky laws, printing expenses, fees and disbursements of the Company's
counsel, independent certified public accountants, and other persons retained
by the Company (all such expenses being herein called "Registration Expenses")
will be borne by the Company. The Holders shall be responsible for all selling
fees, expenses, discounts and commissions relating to the Registered Shares and
for the fees and expenses of counsel and other persons engaged by the Holders
(as well as any costs for any interim audit if requested by the Holder pursuant
to Section 1.2(b)).

                                 ARTICLE THREE
                             REPORTING REQUIREMENTS

       With a view to making available to the Holders the benefits of certain
rules and regulations of the Commission which may at any time permit the sale
of the Registered Shares to the public without registration, the Company agrees
to use its best efforts to (i) make and keep public information available, as
those terms are understood and defined in Rule 144 under the Act and (ii) file
with the Commission in a timely manner all reports and other documents required
of the Company under the Act and the Securities Exchange Act of 1934, as
amended (the "Exchange Act");

                                       5

<PAGE>   6



and (iii) take such further action as any Holder may reasonably request, to the
extent required from time to time to enable such Holder to sell the Registered
Shares without registration under the Act pursuant to the exemptions provided
by Rule 144 or any similar rule or regulation adopted by the Commission.

                                  ARTICLE FOUR
              LIMITATIONS ON REGISTRATION RIGHTS TO OTHER PARTIES

       From and after the date of this Agreement, the Company shall not enter
into any agreement with any holder or prospective holder of any securities of
the Company giving such holder or prospective holder (a) the right to require
the Company, upon any registration of any of its securities, to include, among
the securities which the Company is then registering, securities owned by such
holder, unless under the terms of such agreement, such holder or prospective
holder may include such securities in any such registration only to the extent
that the inclusion of its securities will not limit the number of shares sought
to be included by Holder or reduce the offering price thereof; or (b) the right
to require the Company to initiate any registration of any securities of the
Company. The foregoing limitation shall not apply to registration rights
previously granted by the Company pursuant to its Confidential Private
Placement Memorandum dated September 18, 1996.

                                  ARTICLE FIVE
                                INDEMNIFICATION

       Section 5.1 Indemnification by the Company. In the event of any
registration of the Shares under the Act, the Company agrees to indemnify and
hold harmless Holder and each other person who participates as an underwriter
in the offering or sale of such securities against any and all claims, demands,
losses, costs, expenses, obligations, liabilities, joint or several, damages,
recoveries and deficiencies, including interest, penalties and attorneys' fees
(collectively, "Claims"), to which Holder or underwriter may become subject
under the Act or otherwise, insofar as such Claims (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based
on any untrue statement or alleged untrue statement of any material fact
contained in any registration statement under which Holder's Shares were
registered under the Act, any preliminary prospectus, final prospectus or
summary prospectus contained therein, or any amendment or supplement thereto,
or any omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not
misleading, and the Company will reimburse Holder and each such underwriter for
any legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such Claim (or action or proceeding in respect
thereof); provided that the Company shall not be liable in any such case to the
extent that any such Claim (or action or proceeding in respect thereof) or
expense arises out of or is based on an untrue statement or alleged untrue
statement or omission or alleged omission made in such registration statement,
any such preliminary prospectus, final prospectus, summary prospectus,
amendment or supplement in reliance on and in conformity with written
information furnished to the Company by the Holder expressly for use in the
preparation thereof, and provided, further, that the Company shall not be
liable to any

person who participates as an underwriter in the offering or sale of Registered
Shares or any other person, if any, who controls such underwriter within the
meaning of the Act, in any such case to the extent that any such loss, claim,
damage, liability (or action or proceeding in respect thereof) or expense
arises out of such person's failure to send or give a copy of the Prospectus,
as the same may be then supplemented or amended, to the person asserting an
untrue statement or alleged untrue statement or omission or alleged omission at
or prior to the written confirmation of the sale of Registered Shares to such
person if such statement or omission was corrected in such Prospectus so long
as such Prospectus, and any amendments or supplements thereto, have been
furnished to such underwriter in sufficient numbers and in a timely manner to
permit distribution thereof. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of Holder or any
such underwriter and shall survive the transfer of the Registered Shares by
Holder.

       Section 5.2 Indemnification by Holder. In the event of any registration
of the Registered Shares under the Act, the Holder agrees to indemnify and hold
harmless (in the same manner and to the same extent as set forth in Section
5.1) the Company, each director of the Company, each officer of the Company and
each other person, if any, who controls the Company, within the meaning of the
Act, with respect to any statement or alleged statement in or omission or
alleged omission from such registration statement, any preliminary prospectus
contained therein, or any amendment or supplement thereto, if such statement or
alleged statement or omission or alleged omission was made in reliance on and
in conformity with written information furnished to the Company by the Holder
expressly for use in the preparation of such registration statement,
preliminary prospectus, final prospectus, summary prospectus, amendment or
supplement. Such indemnity shall remain in full force and effect, regardless of
any investigation made by or on behalf of the Company or any such director,
officer or controlling person and shall survive the transfer of the Registered
Shares by Holder.

       Section 5.3 Notices of Claims, etc. Promptly after receipt by an
indemnified party of notice of the commencement of any action or proceeding
involving a Claim referred to in this Article Five, such indemnified party
will, if a claim in respect thereof is to be made against an indemnifying
party, give written notice to the latter of the commencement of such action,
provided that the failure of any indemnified party to give notice as provided
herein shall not relieve the indemnifying party of its obligations under this
Article Five, except to the extent that the indemnifying party is actually
prejudiced by such failure to give notice. In case any such action is brought
against an indemnifying party, unless in such indemnified party's reasonable
judgment a conflict of interest between such indemnified and indemnifying
parties may exist in respect of such Claim, the indemnifying party shall be
entitled to participate in and to assume the defense thereof, jointly with any
other indemnifying party similarly notified to the extent that it may wish,
with counsel reasonably satisfactory to such indemnified party, and after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party shall not be liable to
such indemnified party for any legal or other expenses subsequently incurred by
the latter in connection with the defense thereof other than reasonable costs
of investigation. No indemnifying party shall, without the consent of the
indemnified party, consent to entry of any judgment or enter into any
settlement that does not include as an

                                       7

<PAGE>   8



unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect of such Claim.

       Section 5.4 Indemnification Payments. The indemnification required by
this Article Five shall be made by periodic payments of the amount thereof
during the course of the investigation or defense, as and when bills are
received or expense, loss, damage or liability is incurred.

       Section 6.2 Term of the Agreement. This Agreement shall terminate with
respect to Holder on the earlier to occur of (i) all of the Registered Shares
having been registered as provided in Article One or (ii) two years after the
Preferred Stock is converted in full; provided, however, that the provisions of
Article One shall not terminate if Holder makes a registration request pursuant
to this Agreement which request is currently tolled by reason of one of the
clauses (i) - (iv) in Section 1.2(b), but shall terminate 30 days after notice
of the suspension of such tolling shall have been given to Holder.

       Section 6.3 Mergers, Etc. The Company shall not, directly or indirectly,
enter into any merger, consolidation, or reorganization in which the Company
shall not be the surviving corporation unless the proposed surviving
corporation shall, prior to such merger, consolidation, or reorganization,
agree in writing to assume the obligations of the Company under this Agreement,
and for this purpose references hereunder to "Registered Shares" shall be
deemed to be references to the securities that the Holders would be entitled to
receive in exchange for Registered Shares under any such merger, consolidation,
or reorganization.

       Section 6.4 Entire Agreement. This Agreement contains and constitutes
the entire agreement between and among the parties with respect to the matters
set forth herein and supersedes all prior agreements and understandings between
the parties hereto relating to the subject matter hereof. There are no
agreements, understandings, restrictions, warranties or representations among
the parties relating to the subject matter hereof other than those set forth or
referred to herein. This instrument is not intended to have any legal effect
whatsoever, or to be a legally binding agreement or any evidence thereof, until
it has been signed by all parties hereto.

       Section 6.5 Binding Effect. This Agreement shall be binding on and
enforceable by the Holder and by the Company and its successors. No transferee
of Registered Shares shall acquire any rights under this Agreement except with
the written consent of the Company, which may be withheld for any reason. In
the event the Company is a party to a merger or consolidation in a transaction
in which the Registered Shares are converted into equity securities of another
entity, then the Company shall cause such other entity to assume the Company's
obligations under this Agreement such that this Agreement shall apply to the
equity securities received by the Holder in exchange for the Registered Shares,
unless such equity securities are, upon receipt and without further action by
the Holder, readily salable without registration under the Act.

                               WARRANT AGREEMENT

                                                              December 17, 1997

To the persons whose names appear 
on the signature page of this Agreement 
c/o Cahill, Warnock & Company 
One South Street, Suite 2150
Baltimore, Maryland 21202

Gentlemen:

         In consideration of entering into a transaction composed of a Purchase
Agreement for the sale of Series B Convertible Preferred Stock and Series C
Preferred Stock ("Purchase Agreement") and that certain Loan and Security
Agreement ("Loan Agreement") with Environmental Safeguards, Inc. (the
"Company"), the Company hereby agrees to issue non-redeemable stock purchase
warrants ("Warrants") to the persons whose names appear on Exhibit A of this
Agreement entitling them to purchase an aggregate of 707,142 shares of Company
common stock, $0.001 par value per share ("Common Stock"). The Warrants are
evidenced by warrant certificates in the form attached hereto as Exhibit B
("Warrant Certificate"). The number of shares of Common Stock purchasable upon
exercise of the Warrants is subject to adjustment as provided in Section 4
below. The Warrants will be exercisable by you or any other Warrant holder (as
defined in Section 2(a) below) as to all or any lesser number of shares of
Common Stock covered thereby, at the Purchase Price of $0.01 per share
("Exercise Price"), at any time and from time to time during the period
beginning December 17, 1997 and ending at 5:00 p.m., Houston, Texas time, on
December 16, 2007. The term "Warrant holder" refers to the person whose name
appears on the signature page of this Warrant Agreement and any transferee or
transferees of it permitted by Section 3(a) below. Such term, when used in this
Warrant Agreement in reference to or in the context of a person who holds or
owns shares of Common Stock issued upon exercise of a Warrant, refers where
appropriate to such person who holds or owns such shares of Common Stock.

1.       Representations and Warranties.

         The Company represents and warrants to each Warrant holder as follows:

         (a) Corporate and Other Action. The Company has all requisite power
and authority and has taken all necessary corporate action, to authorize,
execute, deliver and perform this Warrant Agreement, to execute, issue, sell
and deliver the Warrants and Warrant certificates evidencing the Warrants, to
authorize and reserve for issue and, upon payment from time to time of the
Exercise Price, to issue, sell and deliver, the shares of the Common Stock
issuable upon exercise of the Warrants ("Shares"), and to perform all of its
obligations under this Warrant



WARRANT AGREEMENT                                                        PAGE 1
<PAGE>   2



Agreement and the Warrants. This Warrant Agreement and, when issued, each
Warrant issued pursuant hereto, has been or will be duly executed and delivered
by the Company and is or will be a legal, valid and binding agreement of the
Company, enforceable in accordance with its terms. No authorization, approval,
consent or other order of any governmental entity, regulatory authority or
other third party is required for such authorization, execution, delivery,
performance, issue or sale.

         (b) No Violation. The execution and delivery of this Warrant
Agreement, the consummation of the transactions herein contemplated and the
compliance with the terms and provisions of this Warrant Agreement and of the
Warrants will not conflict with, or result in a breach of, or constitute a
default or an event permitting acceleration under, any statute, the Articles of
Incorporation or Bylaws of the Company or any indenture, mortgage, deed of
trust, note, bank loan, credit agreement, franchise, license, lease, permit, or
any other agreement, understanding, instrument, judgment, decree, order,
statute, rule or regulation to which the Company is a party or by which it is
or may be bound.

2.       Exercise of Warrants.

         The Warrants may be exercised by the Warrant holder in whole, or in
part, by surrender of the Warrant Certificate at the office of the Company (or
such other office or agency of the Company as may be designated by notice in
writing to the Warrant holder at the address of such Warrant holder appearing
on the books of the Company) with the subscription form attached hereto duly
completed, at any time within the period beginning on the date hereof and
expiring at 5:00 p.m. Houston, Texas time, on December 16, 2007 (the "Exercise
Period") and by payment to the Company by certified check or bank draft of the
Exercise Price for such shares. The Company agrees that the shares of Common
Stock so purchased shall be and are deemed to be issued to the Warrant holder
as the record owner of such shares of Common Stock as of the close of business
on the date on which the Warrant Certificate shall have been surrendered and
payment made for such shares of Common Stock. Certificates representing the
shares of Common Stock so purchased, together with any cash for fractional
shares of Common Stock paid pursuant to Section 4(f), shall be delivered to the
Warrant holder promptly, and, unless the Warrants have expired, a new Warrant
Certificate representing the number of Warrants represented by the surrendered
Warrant Certificate, if any, that shall not have been exercised also shall be
delivered to the Warrant holder within such time.

3.       Transfer.

         (a) Transferability of Warrants and Shares. The Warrant holder agrees
that the Warrants are being acquired as an investment and not with a view to
distribution thereof (except for partners, limited partners or affiliates of
the Warrant holder) and that the Warrants and the underlying Shares issued on
exercise of the Warrants, may not be transferred, sold, assigned or otherwise
disposed of without registration under the Securities Act of 1933, as amended
(the "Act"), or any exemption therefrom and for which the Company is provided
with an opinion of counsel to 

WARRANT AGREEMENT                                                        PAGE 2

<PAGE>   3

the Warrant holder, reasonably satisfactory to the Company, to the effect that
such transfer is not in violation of any of said securities laws. Any Warrants
issued upon the transfer of a Warrant shall be registered in a Warrant Register
as they are issued. The Company shall be entitled to treat the registered
holder of any Warrant on the Warrant Register as the owner in fact thereof for
all purposes and shall not be bound to recognize any equitable or other claim
to or interest in such Warrant on the part of any other person. Warrants may be
exchanged, at the option of the Holder thereof, for another Warrant, or other
Warrants of different denominations, of like tenor or representing in the
aggregate the right to purchase a like number of shares of Common Stock, upon
surrender to the Company or its duly authorized agent. Notwithstanding the
foregoing, the Company shall have no obligation to cause the Warrants to be
transferred on its books to any person if, in the opinion of counsel to the
Company, this transfer does not comply with the provisions of the Act, and the
rules and regulations thereunder.

         (b) Registration of Shares. You agree not to make any sale or other
disposition of the Shares except pursuant to a registration statement which has
become effective under the Act, setting forth the terms of such offering, the
underwriting discount and commissions and any other pertinent data with respect
thereto, unless the Warrant holder has provided the Company with an opinion of
counsel reasonably acceptable to the Company that such registration is not
required. Notwithstanding the foregoing, the Warrant holder further agrees that
it will not sell, transfer, assign or otherwise dispose of the Shares prior to
December 17,1998, without the prior written consent of the Company.
Certificates representing the Shares shall bear an appropriate legend
reflecting these restriction and shall be subject to a "stop-transfer" order.

         (c) Investment Representations. Each of the Warrant holders,
severally, represent and warrant to the Company as follows:

                  (i) Each Warrant holder which is a corporation, partnership
or trust is duly organized, validly existing and in good standing under the
laws of its jurisdiction of organization, has all requisite power and authority
and has taken all necessary action required for the due authorization,
execution, delivery and performance of this Warrant Agreement, and any other
agreements or instruments executed in connection herewith or therewith and the
consummation of the transactions contemplated herein or therein, and has not
been organized, reorganized or recapitalized specifically for the purposes of
investing in the Company;

                  (ii) Assuming due execution and delivery by the Company of
this Warrant Agreement, this Warrant Agreement to which such Warrant holder is
a party constitutes the legal, valid and binding obligation of such Warrant
holder, enforceable against such Warrant holder in accordance with its terms;

                  (iii) Such Warrant holder has been advised and understands
that neither the Warrants nor the underlying shares of Common Stock have been
registered under the Act, on the basis that no public offering of the Warrants
or underlying shares of Common Stock is to be effected, except in compliance
with applicable securities laws and regulations or pursuant to an exemption

WARRANT AGREEMENT                                                         PAGE 3

<PAGE>   4



therefrom, and that, in this connection, the Company is relying in part on the
representations of such Warrant holders set forth in this Section 3(c);

                  (iv) Such Warrant holder is purchasing the Warrant for
investment purposes, for its own account and not with a view to, or for sale in
violation of Federal or state securities laws; and

                  (v) Such Warrant holder is an "accredited investor" within
the meaning of Rule 501 of Regulation D promulgated under the Act and, by
reason of its business or financial experience, such Warrant holder has the
capacity to protect its own interest in connection with the transactions
contemplated hereunder.

4.       Adjustment of Number of Shares Purchasable.

         The number of Shares to be issued upon exercise of the Warrant is
subject to adjustment from time to time as set forth in this Section 4.

         (a) Stock Dividend; Stock Splits; Reverse Stock Splits;
Reclassifications. In case the Company shall at any time after the date of this
Agreement (i) declare a dividend on the Common Stock in shares of its capital
stock, (ii) subdivide the outstanding Shares, (iii) combine the outstanding
Common Stock into a smaller number of Common Stock, or (iv) issue any shares of
its capital stock by reclassification of the Common Stock (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing corporation), then in each case the number of Shares
of Common Stock for which this Warrant is exercisable shall be adjusted so that
the holder hereof after such time shall be entitled to receive the aggregate
number and kind of Shares which, if such Warrant had been exercised immediately
prior to such time, he would have owned upon such exercise and been entitled to
receive by virtue of such dividend, subdivision, combination, or
reclassification. An adjustment made pursuant to this subsection (a) shall
become effective on the date of the dividend payment, subdivision, combination
or issuance retroactive to the record date with respect thereto, if any, for
such event. Such adjustment shall be made successively whenever any event
listed above shall occur. In the event that at any time, as a result of an
adjustment made pursuant to this subsection (a), the holder hereof shall become
entitled to purchase any securities other than shares of Common Stock,
thereafter the number of such other securities so purchasable upon exercise of
such Warrant and the exercise price thereof shall be subject to adjustment from
time to time in a manner and on terms as nearly equivalent as practicable to
the provisions of this Section 4 with respect to the shares of Common Stock for
which this Warrant shall be exercisable.

         (b) Adjustment of Exercise Price. Whenever the number of shares of
Common Stock purchasable upon the exercise of each Warrant is adjusted pursuant
to Section 4(a), the Exercise Price for each share of Common Stock payable upon
exercise of each Warrant shall be adjusted by multiplying such Exercise Price
immediately prior to such adjustment by a fraction, the numerator of which
shall be the number of shares of Common Stock purchasable upon the exercise

WARRANT AGREEMENT                                                         PAGE 4

<PAGE>   5



of each Warrant immediately prior to such adjustment, and the denominator of
which shall be the number of shares of Common Stock so purchasable immediately
thereafter.

         (c) De Minimis Adjustments. No adjustment in the number of shares of
Common Stock for which this Warrant is exercisable shall be required unless
such adjustment would require an increase or decrease of at least 1% in the
number of shares of Common Stock for which this Warrant is exercisable;
provided, however, that any adjustments which by reason of this subsection (c)
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this Section 4 shall be made
to the nearest one-hundredth of a share.

         (d) Notice of Adjustment. Whenever the number of shares of Common
Stock purchasable upon the exercise of each Warrant or the Exercise Price is
adjusted, as herein provided, the Company shall promptly notify the Warrant
holder in writing (such writing referred to as an "Adjustment Notice") of such
adjustment or adjustments and shall deliver to such Warrant holder a statement
setting forth the number of shares of Common Stock purchasable upon the
exercise of each Warrant and the Exercise Price after such adjustment, setting
forth a brief statement of the facts requiring such adjustment and setting
forth the computation by which such adjustment was made.

         (e) Statement on Warrant Certificates. The form of the Warrant
Certificate need not be changed because of any change in the Exercise Price or
in the number or kind of shares purchasable upon the exercise of a Warrant.
However, the Company may at any time in its sole discretion make any change in
the form of the Warrant Certificate that it may deem appropriate and that does
not affect the substance thereof and any Warrant Certificate thereafter issued,
whether in exchange or substitution for any outstanding Warrant Certificate or
otherwise, may be in the form so changed.

         (f) Fractional Shares. No fractional Shares are to be issued upon the
exercise of any Warrant, but the Company shall pay a cash adjustment in respect
of any fraction of a share which would otherwise be issuable in an amount equal
to such fraction multiplied by the fair value of a share of Common Stock on the
date of such exercise as determined by the board of directors of the Company.

         (g) Capital Reorganization. In case of any capital reorganization of
the Company, or of any reclassification of the Common Stock (other than a
reclassification of the Common Stock referred to in subsection (a) of this
Section 4), or in the case of the consolidation of the Company with or the
merger of the Company into any other Company which does not result in a change
of control, each Warrant shall after such capital reorganization,
reclassification of the Common Stock, consolidation or merger be exercisable,
upon the terms and conditions specified in this Agreement, for the number of
shares of stock or other securities, assets, or cash to which a holder of the
number of shares of Common Stock purchasable (at the time of such capital
reorganization, reclassification of shares, consolidation or merger) upon
exercise of such Warrant would have

been entitled upon such capital reorganization, reclassification of the Common
Stock, consolidation or merger; and in any such case, if necessary, the
provisions set forth in this Section 4 with respect to the rights and interests
thereafter of the holders of the Warrants shall be appropriately adjusted so as
to be applicable, as nearly as may reasonably be, to any shares of stock or
other securities, assets, or cash thereafter deliverable upon the exercise of
the Warrants. The subdivision or combination of the Common Stock at any time
outstanding into a greater or lesser number of shares shall not be deemed to be
a reclassification of the Common Stock for the purposes of this paragraph. The
Company shall not effect any such consolidation or merger unless prior to or
simultaneously with the consummation thereof, the successor corporation (if
other than the Company) resulting from such consolidation or merger or the
corporation purchasing or receiving such assets or other appropriate
corporation or entity shall assume the obligation to deliver to the Warrant
holder such shares of stock, securities, or assets as, in accordance with the
foregoing provisions, such holders may be entitled to purchase, and to perform
the other obligations of the Company under this Warrant Agreement.

5. Covenants of the Company.

         (a) Reservation and Authorization of Common Stock. The Company
covenants and agrees (i) that all shares of Common Stock which may be issued
upon the exercise of the Warrants represented by the Warrant Certificate, upon
issuance and when fully paid for, will be validly issued, fully paid and
nonassessable and free of all taxes, liens, charges, encumbrances and security
interests other than those attaching by or through the Warrant holder, (ii)
that during the Exercise Period, the Company will at all times have authorized,
and reserved for the purpose of issue or transfer upon exercise of the Warrants
evidenced by the Warrant Certificate, sufficient shares of Common Stock to
provide for the exercise of the Warrants represented by the Warrant Certificate
and (iii) that the Company will take all such action as may be necessary to
ensure that the shares of Common Stock issuable upon the exercise of the
Warrants may be so issued without violation of any applicable law or
regulation, or any requirement of any securities exchange upon which any
capital stock of the Company may be listed.

         (b) Replacement of Warrant Certificates. Upon receipt of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of any Warrant Certificate and, in the case of any such loss, theft
or destruction, upon delivery of an indemnity agreement reasonably satisfactory
in form and amount to the Company or, in the case of any such mutilation, upon
surrender and cancellation of such Warrant Certificate, the Company, at the
expense of the Warrant holder, will execute and deliver, in lieu thereof, a new
Warrant Certificate of like tenor.

         (c) Reporting by the Company. The Company agrees that during the term
of the Warrants it will use its best efforts to keep current in the filing of
all forms and other materials, if any, which it may be required to file with
the appropriate regulatory authority pursuant to the Securities Exchange Act of
1934, as amended ("Exchange Act"), and all other forms and reports required to
be filed with any regulatory authority having jurisdiction over the Company.

6.       No Rights of Stockholder.

         The Warrant holder shall not be entitled to vote or to receive
dividends or shall otherwise be deemed to be the holder of shares of Common
Stock for any purpose, nor shall anything contained herein or in any Warrant
Certificate be construed to confer upon the Warrant holder, as such, any of the
rights of a stockholder of the Company or any right to vote upon or give or
withhold consent to any action of the Company (whether upon any reorganization,
issuance of securities, reclassification or conversion of Common Stock,
consolidation, merger, sale, lease, conveyance, or otherwise), receive notice
of meetings or other action affecting stockholders (except for notices
expressly provided for herein) or receive dividends or subscription rights,
until the Warrant Certificate shall have been surrendered for exercise
accompanied by full and proper payment of the Exercise Price as provided herein
and shares of Common Stock hereunder shall have become issuable and until the
Warrant holder shall have been deemed to have become a holder of record of such
shares. The Warrant holder shall not, upon the exercise of Warrants, be
entitled to any dividends if the record date with respect to payment of such
dividends shall be a date prior to the date such shares of Common Stock became
issuable upon the exercise of such Warrants. Notwithstanding the foregoing,
this Section 6 shall not affect a Warrant holder's rights as a stockholder
pursuant to his or its ownership of Common Stock or Preferred Stock of the
Company.

7.       Miscellaneous.

         All notices, certificates and other communications from or at the
request of the Company to any Warrant holder shall be delivered personally, by
prepaid overnight courier, by facsimile transmission or by certified mail,
return receipt requested, addressed to the Warrant Holder at its address as it
appears on the books of the Company. This Warrant Agreement and any of the
terms hereof may be changed, waived, discharged or terminated only by an
instrument in writing signed by the party against which enforcement of such
change, waiver, discharge or termination is sought. This Warrant Agreement
shall be construed and enforced in accordance with and governed by the laws of
the State of Maryland. The headings in this Warrant Agreement are for purposes
of reference only and shall not limit or otherwise affect any of the terms
hereof. This Warrant Agreement, together with the forms of instruments annexed
hereto as exhibits, constitutes the full and complete agreement of the parties
hereto with respect to the subject matter hereof.
This Warrant Agreement may be executed in counterparts.

                              EMPLOYMENT AGREEMENT

         THIS EMPLOYMENT AGREEMENT ("Agreement"), between ENVIRONMENTAL
SAFEGUARDS, INC., a Nevada corporation, having its principal office and place
of business in Houston, Texas (hereinafter referred to as the "Company") and
JAMES S.  PERCELL, a resident of Harris County, Texas (hereinafter referred to
as the "Employee").

                                R E C I T A L S:

         WHEREAS, the Company is engaged in the development, production and
sale of environmental remediation technologies and services.; and

         WHEREAS, the Company desires to employ the Employee in the capacity of
the President and Chief Executive Officer of the Company to manage the
day-to-day operations of the Company's business and its expansion efforts and
the Employee desires to be so employed under this Agreement, subject to the

                            CONDITIONS OF AGREEMENT

                                       I.
                                 CONSIDERATION

         This Agreement is executed and delivered for good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged.
The special training and knowledge acquired or to be acquired by the Employee
during employment are material factors relating to the employment of the
Employee without which the employment relationship would not be commenced.  The
parties hereto acknowledge and agree that this Agreement is necessary to
protect the Company's legitimate interests, including, but not limited to, its
business goodwill, trade secrets and other confidential or proprietary
information.

                                      II.
                               TERM OF EMPLOYMENT

         2.1     Term.  The Company hereby employs the Employee, and the
Employee hereby accepts employment with the Company for a term of  three (3 )
years ("Initial Term") which shall commence on the 1st day of April, 1997 and
shall continue for the entire Initial Term, subject to earlier termination as
provided in this Agreement.

         2.2     Extension of Initial Term.  After the expiration of the
Initial Term, this Agreement will be automatically extended for additional and
successive one (1) year periods, unless either party gives written notice to
the other at least 30 days prior to the expiration of the Initial Term, or any
one year renewal term, that such automatic extension shall not occur, in which
event Employee's employment shall terminate upon the expiration of the Initial
Term, or such renewal term, whatever the case may be.  The terms and conditions
then in effect at the end of the Initial Term, or any

renewal term, shall control during the succeeding renewal term unless otherwise
set forth herein or mutually agreed to in writing.

                                      III.
                               DUTIES OF EMPLOYEE

         3.1     Duties.  The Employee is hereby employed as President and
Chief Executive Officer of the Company.  The Employee's responsibilities for
such office shall be as set forth in the Bylaws of the Company including
managing the day-to-day operations of the Company's business and its ongoing
expansion efforts.  Generally, in his capacity as President and Chief Executive
Officer of the Company, the Employee will be primarily responsible for the
general supervision, direction, and control of the business and officers of the
Company, subject to the control of the Board of Directors.  In the discharge of
such duties and throughout Employee's employment with Company, Employee shall,
with respect to conduct involving certain matters including, but not limited
to, conflicts of interest and usurpation of corporate authority, comply with
(i) all requirements imposed by the Company upon similarly situated employees
of the Company; (ii) standards generally accepted within the business community
regarding similarly situated persons; and (iii) any relevant legal authority.
Should the Company determine at a regularly or specially called meeting of the
Board of Directors, held with proper notice, that Employees performance is in
question, the Employee will be notified in writing and provided 30 days to
present a plan to conform to the requests of the Company.

         3.2     Change in Duties.  The duties of Employee shall be those
assigned to him from time to time by the Company and may be changed by Company
from time to time without resulting in rescission or termination of this
Agreement.

         3.3     Engaging in Other Employment.  The Employee shall devote such
productive time, ability, and attention to the business of the Company during
the term of this Agreement as is required to fulfill his duties and
responsibilities as set forth in Section 3.1 above.  During the period of
employment, the Employee further agrees not to (i) solely or jointly with
others undertake or join any planning for or organization of any business
activity competitive with the business activities of the Company, and (ii)
directly or indirectly, engage or participate in any other activities in
conflict with the best interest of the Company.  Notwithstanding anything
herein contained to the contrary, the Employee shall be able to devote such
time as he deems reasonably necessary to his own private investments and
affairs, so long as the performance of the Employee hereunder is not impaired
and the covenants contained herein are not violated.

                                      IV.
                            COMPENSATION TO EMPLOYEE

         4.1.    Yearly Salary.  During the Initial Term of this Agreement, the
Employee shall be entitled to a yearly salary of $125,000.00, less all payroll
deductions and applicable taxes.  The time of payment for each installment
shall be consistent with the general business practices of the Company.  Such
salary shall be reviewed annually and shall remain fixed or be increased to the
extent deemed appropriate by the Board of Directors of the Company.

<PAGE>   3
         4.2     Other Compensation.  The Employee understands and agrees that
any additional compensation to the Employee (whether a bonus or other form of
additional compensation) shall rest in the sole discretion of the Board of
Directors (or any Compensation Committee consisting of members of the Board of
Directors) and shall be based upon the performance of the Company as well as
participation in all benefit plans maintained by the Company for salaried
employees.

         4.3     Review.  The Employee, after the Initial Term, if still
employed by the Company, shall be reviewed at such times as are consistent with
the Company's general personnel policies.

         4.4     Fringe Benefits-Employee Benefits Plan.  The Employee shall be
entitled to participate on an equitable basis, as the Board of Directors may,
in the exercise of its discretion deem appropriate, in any stock option plan
and any additional year-end or other profit sharing or incentive or deferred
compensation arrangements, whether provided for in stock, cash or otherwise,
which the Company may distribute to or provide for officers and employees
generally, or for a limited or selected group, as well as under any other
plans, benefits, customs or practices now or hereinafter made available to
other executives of the Company, including as examples only, group life
insurance and medical insurance.  The Company may terminate, amend or modify
any or all such plans at any time and may choose not to adopt additional plans.
The Employee's rights under any benefits plans now in force or later adopted by
the Company shall be governed solely by their terms.

         4.5     Expense Account.  The Employee is authorized to incur
reasonable and necessary expenses directly associated with the promotion of the
interests of the Company, and the performance of his assignments, including
expenditures for entertainment and travel.  The Company will reimburse the
Employee from time to time for all such business expenses, upon the Employee's
presenting to the Company such information and support as prescribed by Company
policy.

         4.6     Holidays and Vacations.  The Employee shall be entitled to at
least three (3) weeks of paid vacation for each year during the term hereof.
Additionally, the Employee shall be entitled to such fully paid holidays as are
normally taken by other full time employees of businesses similar to the
Company, and such other holidays which may be particular to the Employee's
religious preference.

                                       V.
                                 LIFE INSURANCE

         At any time during the term of this Agreement, the Company shall have
the right to insure the Employee's life for the Company's sole benefit, and to
determine the amount and type of insurance and type of policy.  The Company
shall be required to pay all premiums due on such policies.  The Employee shall
cooperate with the Company in taking out insurance by submitting to physical
examination(s), by supplying all information required by the insurance company,
and by executing any and all other necessary documents.  The Employee shall
incur no financial obligation by executing the required documents and shall
have no interest in any such policies, except as otherwise provided herein.

                                      VI.
                           TERMINATION OF EMPLOYMENT

         6.1     Termination by the Employee Without Cause.  If the employment
of the Employee is terminated by the Employee for any reason other than as set
forth in the other paragraphs of this Article VI (such termination being herein
defined as "without cause"), the Employee shall give the Company thirty (30)
days written notice of termination; provided, however, that the Employee shall
not be entitled to terminate his employment with the Company during the Initial
Term without cause.  Except as otherwise provided for herein, any such
termination of the Employee's employment for any reason whatsoever, whether
voluntary or involuntary, shall not prejudice any other remedy to which any
party may be entitled either at law, in equity, or under this Agreement.

         6.2     Termination for Cause by the Company.  The Company may "for
cause" terminate the employment of the Employee at any time (after giving
Employee notice to cure pursuant to Paragraph 3.1, if such termination is the
result of violations of Paragraph 6.2A or 6.2B below) with 30 days notice..
"For cause" for the purpose of this Agreement is defined as:

         A.      The willful and continued failure to substantially perform his
duties as set forth in this Agreement;

         B.      The breach by the Employee of any of the provisions of this
Agreement or of the covenants contained in Article VII of this Agreement; or

         C.      If the Employee is convicted of any crime involving moral

                             RESTRICTIVE COVENANTS

         7.1     Definition.  The Employee hereby acknowledges that during the
course of his employment with the Company, he will have access to and will
become familiar with various trade secrets and other proprietary and
confidential information which are owned by the Company and which are used in
the operation of the Company's business.  "Trade secrets and other proprietary
and confidential information" consist of, for example, and not intending to be
inclusive, (i) methods of doing business; (ii) financial information,
consisting of financial cost, and sales data and other information; (iii)
personnel information (iv) lists of customers and accounts, contracts, sales
information, pricing list, vendor and supplier list of the Company; (v) other
information of a confidential nature which must remain confidential for the
continuing success of the Company; and (vi) such other information concerning
the business of the Company and the Company's goodwill.

         7.2     Non-Disclosure and Confidentiality Covenants.  The Employee
acknowledges that the Company's trade secrets and other proprietary and
confidential information, as they may exist from time to time, are valuable,
special and unique assets of the Company's business.  Additionally, Employee
acknowledges that the business goodwill and business contacts of the Company
are the sole property of the Company and are among the Company's most valuable
business property.  Therefore, in consideration of the mutual promises herein
contained, and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, and to protect the foregoing
valuable property of the Company, the Employee expressly covenants and agrees
as follows:

         Except as required in the course of his employment with the Company,
         the Employee will not, during and after the termination of his
         employment:

                 (1)      Disclose, directly or indirectly, the Company's trade
         secrets and other proprietary and confidential information, or any
         part thereof, to any person, firm, corporation, association or other
         entity for any reason or purpose whatsoever; or

                 (2)      Directly or indirectly use the Company's trade
         secrets and other proprietary and confidential information, or any
         part thereof, for his own purpose or for his own benefit in any
         activity of any nature whatsoever.

         7.3     Return of Company's Property.  The Employee covenants and
agrees that, upon the request of the Company or upon termination of employment,
the Employee shall turn over to the Company all files, records, documents,
drawings, presentations, specifications, equipment, disks or other computer
media, data, computer printouts, records, written materials and similar items
relating to the business of the Company, and any other property of the Company
in his possession or under his control.  In the event the Employee fails to
return the Company's property when required or requested to do so, the Company
may, in addition to any other remedy provided by law, withhold any amounts due
the Employee until full compliance with this Paragraph 7.3.

<PAGE>   6
         7.4     Covenant Not to Compete.  So long as the Employee is employed
by the Company and for a period of eighteen (18) months after either (i) the
voluntary termination of employment by Employee or (ii) the termination of the
Employee by the Company for cause, as set forth in Section 6.2 hereof, the
Employee specifically agrees that he will not, for himself, on behalf of, or in
conjunction with any person, firm, corporation or entity, other than the
Company (either as principal, employee, shareholder, member, director, partner,
consultant, owner or part-owner of any corporation, partnership or any type of
business entity) anywhere in any county in which the Company is doing business
at the time of termination, directly or indirectly, own, manage, operate,
control, be employed by, participate in, or be connected in any manner with the
ownership, management, operation, or control of any business similar to the
type of business conducted by the Company at the time of termination of the
Employee's employment.

         7.5     Employee's Acknowledgments and Agreements.  The Employee
           acknowledges and agrees that:

                 (1)      Due to the nature of the Company's business, the
         foregoing covenants place no greater restraint upon the Employee than
         is reasonably necessary to protect the business and goodwill of the
         Company;

                 (2)      These covenants protect a legitimate interest of the
         Company and do not serve solely to limit the Company's future
         competition;

                 (3)      This Agreement is not an invalid or unreasonable
         restraint of trade;

                 (4)      A breach of these covenants by the Employee would
         cause irreparable damage to the Company;

                 (5)      These covenants will not preclude the Employee from
         becoming gainfully employed following termination of employment with
         the Company;

                 (6)      These covenants are reasonable in scope and are
         reasonably necessary to protect the Company's business and goodwill
         and valuable and extensive trade which the Company has established
         through its own expense and effort;

                 (7)      The signing of this Agreement is necessary for the
         Employee's employment; and

                 (8)      He has carefully read and considered all provisions
         of this Agreement and that all of the restrictions set forth are fair
         and reasonable and are reasonably required for the protection of the
         interests of the Company.

         7.6     Remedies, Injunction.  In the event of the Employee's actual
or threatened breach of any provisions of this Agreement, the Employee agrees
that the Company shall be entitled to a temporary restraining order,
preliminary injunction and/or permanent injunction restraining and enjoining
the Employee from violating the provisions herein.  Nothing in this Agreement
shall be

                                     Page 6
<PAGE>   7
construed to prohibit the Company from pursuing any other available remedies
for such breach or threatened breach, including the recovery of damages from
the Employee.  The Employee further agrees that for the purpose of any such
injunction proceeding, it shall be presumed that the Company's legal remedies
would be inadequate and that the Company would suffer irreparable harm as a
result of the Employee's violation of the provisions of this Agreement.  In any
proceeding brought by the Company to enforce the provisions of this Agreement,
no other matter relating to the terms of any claim or cause of action of the
Employee against the Company will be defense thereto.  The foregoing remedy
provisions are subject to the provisions of Section 15.15 of the Texas Business
and Commerce Code, as amended (the "Code"), which Code provisions shall control
in the event of any conflict between the provisions hereof and the Code or any
other law in effect relevant and applicable hereto.

         7.7     Severability.  In the event that any of the provisions of this
Agreement are held to be invalid or unenforceable in whole or in part, those
provisions to the extent enforceable and all other provisions shall
nevertheless continue to be valid and enforceable as though the invalid or
unenforceable parts had not been included in this Agreement.  In the event that
any provision relating to the time period or scope of a restriction shall be
declared by a court of competent jurisdiction to exceed the maximum time period
or scope such court deems reasonable and enforceable, then the time period or
scope of the restriction deemed reasonable and enforceable by the court shall
become and shall thereafter be the maximum time period or the applicable scope
of the restriction.  The Employee further agrees that such covenants and/or any
portion thereof are severable, separate and independent, and should any
specific restriction or the application thereof, to any person, firm,
corporation, or situation be held to be invalid, that holding shall not affect
the remainder of such provisions or covenants.
