$8,000 when that figure is correctly reported as $80,000. A corrected Condensed
Consolidated Statements of Cash Flows is filed herewith.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.  BASIS OF PRESENTATION

    The condensed consolidated financial statements have been prepared pursuant
to the rules and regulations of the SEC. Certain information and footnote
disclosures, normally included in annual financial statements prepared in
accordance with generally accepted accounting principles, have been condensed or
omitted pursuant to those rules and regulations; although the Company believes
that the disclosures made are adequate to make the information presented not
misleading. In the opinion of management, all adjustments, consisting only of
normal recurring adjustments, necessary to fairly present the financial
position, results of operations and cash flows with respect to the interim
consolidated financial statements, have been included. The results of operations
for the interim periods are not necessarily indicative of the results for the
entire year.

    It is suggested that these condensed consolidated financial statements be
read in conjunction with the audited consolidated financial statements and notes
thereto included in the Company's Annual Report on Form 10-K for the year ended
December 31, 1997, as filed with the SEC.

2.  INVENTORIES

    Inventories are stated at the lower of cost or market and, at December 31,
1997 and June 30, 1998, consisted of processed by-products of $435,000 and
$805,000, respectively, and unprocessed by-products of $132,000 and $236,000,
respectively. Cost is determined using the first-in, first-out (FIFO) method.

3.  EARNINGS PER SHARE

    Effective December 15, 1997, the Company adopted the provisions of Statement
of Financial Accounting Standards (SFAS) No. 128, "Earnings Per Share". Under
these provisions, earnings per share amounts are based on the weighted average
number of shares of common stock and common stock equivalents outstanding during
the period. The weighted average number of shares used to compute basic and
diluted earnings per share for the three and six months ended June 30, 1997 and
1998, respectively, is illustrated below:

4.  NEW ACCOUNTING PRONOUNCEMENTS

    In March 1998, the AICPA issued Statement of Position (SOP) 98-1,
"Accounting for the Costs of Computer Software Developed or Obtained for
Internal Use". The SOP provides guidance with respect to accounting for the
various types of costs incurred for computer software developed or obtained for
the Company's use. The Company intends to adopt SOP 98-1 in the first quarter of
1999 and believes that adoption will not have a significant effect on its
consolidated financial statements.

    In April 1998, the AICPA issued SOP 98-5, "Reporting on the Costs of
Start-Up Activities". At adoption, SOP 98-5 requires the Company to write off
any unamortized start-up costs as a cumulative change in accounting principle
and expense all future start-up costs as they are incurred. The Company intends
to adopt SOP 98-5 in the first quarter of 1999 and believes that adoption will
not have a significant effect on its consolidated financial statements.

5.  ACQUISITIONS

    FOURTH QUARTER 1997 ACQUISITIONS

    During the fourth quarter of 1997, the Company completed four acquisitions
that were accounted for under the purchase method of accounting. Results of
operations of companies that were acquired and subject to purchase accounting
are included in the consolidated financial statements from the dates of such
acquisitions. The total costs of acquisitions accounted for under the purchase
method were $6,819,000. The accompanying condensed consolidated balance sheet as
of June 30, 1998 includes allocations of the respective purchase prices and is
subject to final adjustment. The excess of the aggregate purchase price over the
fair value of the net assets acquired was approximately $5,726,000.

    In addition, the Company has agreed in connection with certain transactions
to pay additional amounts to the sellers upon the achievement by the acquired
businesses of certain negotiated goals, such as targeted earnings levels.
Although the amount and timing of any payments of additional contingent
consideration depend on whether and when these goals are met, the maximum
aggregate amount of contingent consideration potentially payable if all targeted
goals are met is approximately $27,880,000 (payable through 2002) with the
achieved goals providing approximately $31,125,000 of pre-tax income over a
five-year period. The contingent consideration is payable in cash or, in some
instances, cash and stock, at the Company's option.

    On October 1, 1997, the Company completed a merger accounted for as a
pooling-of-interests, pursuant to which the Company issued 241,410 shares of its
common stock in exchange for all outstanding shares of the acquired company.
Periods prior to consummation of this merger were not restated to include the
accounts and operations of the acquired company as combined results are not
materially different from the results as presented.

    FIRST AND SECOND QUARTER 1998 ACQUISITIONS

    During the six months ended June 30, 1998, the Company acquired or
contracted to acquire seventeen businesses engaged in the collection, treatment
and disposal of liquid wastes for approximately $69,033,000 in cash, $1,226,000
in debt issued, 20,000 stock warrants and 1,355,039 shares of the Company's
common stock using the purchase method of accounting. In addition, one
acquisition provides for additional payments of approximately $15,004,000 in
connection with a five-year disposal agreement entered into with the seller,
which the Company has accrued for as a contract reserve. All of these
acquisitions were consummated during the first six months of 1998 except for the
acquisition from USA Waste Services, Inc. ("USA Waste") of one business in
Florida with approximately $6.6 million in 1997 revenues (the "Universal Waste
Acquisition"), which was consummated on August 1, 1998. Pending the consummation
of the Universal Waste Acquisition, USA Waste operated the business on terms
that had the same effect on the Company's financial condition and results of
operations as if the acquisition had been consummated on May 1, 1998. The
accompanying condensed consolidated balance sheet includes allocations of the
respective purchase prices and is subject to final adjustment. The excess of the
aggregate purchase price over the fair value of the net assets acquired was
approximately $85,773,000.

    In addition, the Company has agreed in connection with certain transactions
to pay additional amounts to the sellers upon the achievement by the acquired
businesses of certain negotiated goals, such as targeted earnings levels, or the
occurrence of other specified events. Although the amount and timing of any
payments of additional contingent consideration depend on whether and when these
goals or other conditions are met, the maximum aggregate amount of contingent
consideration potentially payable if all targeted goals are met is approximately
$14,225,000 (payable through 2001) with the achieved goals providing
approximately $25,988,000 of pre-tax income or earnings before

                                        8
<PAGE>
interest, taxes, depreciation and amortization over a three-year period. The
contingent consideration is generally payable in cash, however, in three of the
acquisitions, the contingent consideration involves shares of the Company's
common stock.

    The unaudited pro forma information set forth below presents the revenues,
net income and earnings per share of the Company, plus the 1997 and 1998
acquisitions, the initial public offering and the secondary offering of common
stock, as if these transactions were effective on the first day of the period
being reported and includes certain pro forma adjustments, including the
adjustment of amortization expenses to reflect purchase price allocations,
recording of interest expense to reflect debt issued in connection with the
acquisitions, and certain reductions of salaries and benefits payable to the
previous owners of the businesses acquired which were agreed to in connection
with the acquisitions and the related income tax effects of these adjustments.

beginning of the periods presented.

6.  LEGAL PROCEEDINGS

    On August 7, 1998, the Company settled substantially all of the claims
asserted against it in the three previously reported lawsuits relating to its
Bourg, Louisiana landfarm and a fourth lawsuit filed against the Company in July
1998 seeking injunctive relief against certain operations of the Bourg,
Louisiana landfarm. Under the terms of the settlement, the Company agreed to
expand the buffer zone along the western boundary of its landfarm. In addition,
the Company agreed to construct a berm along the property line closest to the
residences of the plaintiffs. The costs of these actions had previously been
reserved for by the Company and, thus, did not have any impact on earnings. This
settlement does not resolve certain claims asserted against the Company by
Acadian Shipyard, Inc., a local barge company ("Acadian"), in the FRILOUX ET AL.
V. CAMPBELL WELLS CORPORATION case pending in the 17th Judicial District Court
for the Parish of Lafourche, Louisiana. In the FRILOUX case, the Company has
asserted claims for indemnity and/or contribution against Acadian. Thereafter,
in July 1998, Acadian filed various counterclaims against the Company including,
without limitation, claims for defamation of business reputation and conspiracy
to damage Acadian's business reputation. In addition, Acadian requested
unspecified monetary damages allegedly suffered as a result of alleged
environmental contamination in connection with the ongoing operations at the
Bourg, Louisiana landfarm. The Company denies that it has any liability to
Acadian and intends to vigorously defend itself against these claims. In
addition, this settlement does not resolve the claims asserted in the class
action filed in the Civil District Court for the Parish of Orleans, Louisiana
seeking

                                        9
<PAGE>
unspecified monetary damages allegedly suffered as a result of alleged air,
water and soil contamination in connection with ongoing operations at the
Company's Mermentau, Louisiana landfarm. The Company has not been named as a
defendant in this class action; however, there can be no assurance that the
Company will not subsequently be named as a defendant.

    In July 1998, the Company commenced an arbitration proceeding against
Newpark Resources, Inc. ("Newpark") for failing to satisfy its delivery and
payment obligations under a long-term disposal agreement (the "Disposal
Agreement") that the Company acquired in connection with its acquisition of its
Louisiana and Texas landfarms in December 1996. Specifically, the Company has
alleged that Newpark has fallen short of its delivery obligations under the
Disposal Agreement by approximately 635,000 barrels of oilfield waste valued at
approximately $3.5 million. The Company has requested that the arbitrators enter
an order (i) declaring that Newpark has breached the Disposal Agreement and no
condition existed or exists which would excuse Newpark's breach and (ii)
awarding the Company approximately $3.5 million in damages. The arbitrators for
the arbitration proceeding have not yet been selected and, thus, Newpark has not
responded to the claims asserted by the Company.

    The Company is, from time to time, a party to litigation arising in the
normal course of its business, most of which involves claims for personal injury
or property damage incurred in connection with its operations. Except as
described above, the Company is not currently involved in any litigation that it
believes will have a material adverse effect on its business, results of
operations or financial condition.

7.  SUBSEQUENT EVENTS

    Since June 30, 1998, the Company has acquired four additional businesses,
which collectively had 1997 revenues of approximately $1.5 million. Each of
these acquisitions has been accounted for under the purchase method of
accounting. The total consideration for these four acquisitions involved
approximately $1.9 million in cash and assumed debt and 7,786 shares of the
Company's common stock. In two of these acquisitions, the Company agreed to make
additional payments of cash to the sellers upon the achievement by the acquired
businesses of targeted earnings levels. In addition, on August 1, 1998, the
Company consummated the Universal Waste Acquisition.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

    THE FOLLOWING DISCUSSION SHOULD BE READ IN CONJUNCTION WITH THE
COMPANY'S UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS AND THE RELATED
NOTES THERETO INCLUDED ELSEWHERE IN THIS REPORT.

OVERVIEW

    The Company is a rapidly growing provider of integrated liquid waste
management services, including collection, processing, recovery and disposal
services. Since its formation in November 1996, the Company has pursued an
aggressive acquisition program, acquiring 29 liquid waste management businesses.

    The Company provides liquid waste management services through a number of
subsidiaries that are organized into two divisions. The Industrial Wastewater
Division collects, processes and disposes of liquid waste (such as industrial
wastewater, grease and grit trap waste, bulk liquids and unsaleable beverages
and certain hazardous wastes) and whenever feasible recovers saleable
by-products from the waste streams. Typically, the Company uses a variety of
physical, chemical, thermal and biological techniques to break down the liquid
waste into constituent components. Water extracted from the liquid waste is
pretreated and then discharged into the local publicly-owned treatment works and
solid materials are dried and disposed of in a solid waste landfill. The
Oilfield Waste Division processes and disposes of waste generated in oil and gas
exploration and production. The Oilfield Waste Division was formed in December
1996 when the Company purchased its Louisiana and Texas landfarms (the "Campbell
Wells Acquisition") from Campbell Wells, L.P. and Campbell Wells Norm, L.P.
(collectively, "Campbell Wells") and Sanifill, Inc. ("Sanifill"), each of which
is now a wholly-owned subsidiary of USA Waste Services, Inc. ("USA Waste").

    The Industrial Wastewater Division generated $24.6 million, or 87.9%, of the
Company's revenues for the quarter ended June 30, 1998. This Division derives
revenues from two principal sources: tipping and collection fees received for
processing and disposing of waste, and revenue obtained from the sale of
by-products, including fats, oils, feed proteins, industrial and fuel grade
ethanol, solvents, aluminum, glass, plastic and cardboard recovered from waste
streams. Some of the Company's by-product sales involve the brokering of
industrial and fuel grade ethanol produced by third parties in order to meet its
customers' volume and quality requirements. Tipping and collection fees charged
to customers vary per gallon by waste stream according to the constituents of
the waste, expenses associated with processing the waste and competitive
factors. By-products are commodities and their prices fluctuate based on market
conditions. The Company anticipates that revenues from tipping and collection
fees, which have higher margins than by-product sales, will increase at a faster
rate than revenues from sales of by-products and brokering of ethanol. The
Company anticipates that the Industrial Wastewater Division will represent a
growing share of the Company's business because of its projected internal growth
and future acquisitions.

    The Oilfield Waste Division generated $3.4 million, or 12.1%, of the
Company's revenues for the quarter ended June 30, 1998. This Division derives
revenues from fees charged to customers for processing and disposing of oil and
gas exploration and production waste. These fees are based on the composition of
the waste and currently range from $0.40 per barrel for saltwater to $6.75 to
$10.75 per barrel for oil-based drilling fluids, depending upon the makeup of
the waste. Accordingly, the Company believes that total revenues are a better
indicator of performance than is the average fee charged. When waste is unloaded
at a given site, the Company recognizes the related revenue and records a
reserve for the estimated amount of expenses to be incurred to process the waste
in order to match revenues with their related costs. As processing occurs,
generally over nine to twelve months, the reserve is depleted as expenses are
incurred.

                                       11
<PAGE>
The Company's operating margins in the Oilfield Waste Division are typically
higher than in the Industrial Wastewater Division.

    Newpark Resources, Inc. ("Newpark") is the largest customer of the Oilfield
Waste Division. Under the terms of a long-term disposal agreement (the "Disposal
Agreement") that the Company acquired in connection with the Campbell Wells
Acquisition, Newpark is obligated to deliver to the Company annually the lesser
of (i) one-third of the barrels of oilfield waste that Newpark receives for
processing and disposal in Louisiana, Texas, Mississippi, Alabama and the Gulf
of Mexico, and (ii) 1,850,000 barrels of oilfield waste, in each case excluding
saltwater. The contract price is $5.50 per barrel, adjusted semi-annually
beginning June 30, 1998, with a price floor of $5.50 per barrel. As further
described in "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and in "Legal Proceedings" below, a dispute has arisen
with respect to Newpark's obligations under the Disposal Agreement and the
Company has initiated an arbitration proceeding seeking declaratory relief,
specific performance of the Disposal Agreement and monetary damages.

    Operating expenses include compensation and overhead related to operations
workers, supplies and other raw materials, transportation charges, disposal fees
paid to third parties, real estate lease payments and energy and insurance costs
applicable to waste processing and disposal operations.

    Selling, general and administrative expenses include management, clerical
and administrative compensation and overhead relating to the Company's corporate
offices and each of its operating sites, as well as professional services and
costs.

    Depreciation and amortization expenses relate to the Company's landfarms and
other depreciable or amortizable assets. Landfarms, which constitute
approximately 20.8% of the Company's net property, plant and equipment, are
amortized over 25 years. Other depreciable or amortizable assets are expensed
over periods ranging from three to 40 years. Amortization expenses relating to
acquisitions have not been significant in the past, but will increase as a
result of amortization of goodwill recorded in connection with acquisitions
completed since December 31, 1997 and future acquisitions.

    The timing and magnitude of acquisitions, assimilation costs and the
seasonal nature of the operations of the Oilfield Waste Division may materially
affect operating results. Accordingly, the operating results for any period are
not necessarily indicative of the results that may be achieved for any
subsequent period.

RESULTS OF OPERATIONS

THREE MONTHS ENDED JUNE 30, 1997 AND 1998

     REVENUES. Revenues for the quarter ended June 30, 1998 increased $18.1
million, or 183.3%, from $9.9 million for the quarter ended June 30, 1997 to
$28.0 million for the quarter ended June 30, 1998. The Industrial Wastewater
Division contributed $4.2 million, or 42.8%, of second quarter 1997 revenues and
$24.6 million, or 87.9%, of second quarter 1998 revenues. Tipping and collection
fees generated $1.2 million, or 28.2%, and $18.2 million, or 73.9%, of the
Industrial Wastewater Division's revenues for the second quarters of 1997 and
1998, respectively. By-product sales generated the remaining $3.0 million, or
70.7%, and $6.4 million, or 25.8%, of the Industrial Wastewater Division's
revenues for the second quarters of 1997 and 1998, respectively. The Oilfield
Waste Division contributed $5.7 million, or 57.2%, of second quarter 1997
revenues and $3.4 million, or 12.1%, of second quarter 1998 revenues.

    The revenues of the Industrial Wastewater Division increased $20.4 million,
or 484.1%, from $4.2 million for the quarter ended June 30, 1997 to $24.6
million for the quarter ended June 30, 1998 due to acquisitions

                                       12
<PAGE>
completed during the fourth quarter of 1997 and the first six months of 1998 and
an increase in the volume of waste processed resulting primarily from the
enactment of state-wide "full-pump" regulations in Texas. The Oilfield Waste
Division's revenues decreased $2.3 million, or 40.3%, from $5.7 million for the
quarter ended June 30, 1997 to $3.4 million for the quarter ended June 30, 1998.
The revenues of the Oilfield Waste Division were down due to lower receipts of
oilfield waste from Newpark under the Disposal Agreement. During the three month
period ended June 30, 1998, Newpark delivered approximately 133,500 barrels of
oilfield waste (excluding saltwater) to the Company's landfarms, as compared to
approximately 393,200 barrels of oilfield waste (excluding saltwater) delivered
during the three month period ended June 30, 1997. Pending the resolution of the
arbitration proceeding described in "Legal Proceedings" below, the Company
anticipates that Newpark's deliveries of oilfield waste to the Company will be
substantially less than that mandated by the Disposal Agreement. While the
Company believes that it will prevail in the arbitration proceeding, it has
elected to record the dollar value associated with the volume shortfall,
utilizing the rate set in the Disposal Agreement, as deferred revenue.

     OPERATING EXPENSES. Operating expenses increased $12.4 million, or 227.4%,
from $5.5 million for the quarter ended June 30, 1997 to $17.9 million for the
quarter ended June 30, 1998. As a percentage of revenues, operating expenses
increased from 55.4% in the second quarter of 1997 to 64.1% in the second
quarter of 1998. This increase was due primarily to the Company's transition
from operating primarily as an oilfield waste disposal company into an
integrated liquid waste management company providing collection, processing,
recovery and disposal services.

     DEPRECIATION AND AMORTIZATION. Depreciation and amortization expenses
increased $1.4 million, or 217.9%, from $641,000 for the quarter ended June 30,
1997 to $2.0 million for the quarter ended June 30, 1998. As a percentage of
revenues, depreciation and amortization expenses increased from 6.5% in the
second quarter of 1997 to 7.3% in the second quarter of 1998. This increase was
primarily due to an increase in capital expenditures and additional amortization
associated with the acquisitions completed in 1998.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased $1.8 million, or 117.3%, from $1.6 million for
the quarter ended June 30, 1997 to $3.4 million for the quarter ended June 30,
1998. As a percentage of revenues, selling, general and administrative expenses
decreased from 15.9% for the second quarter of 1997 to 12.2% for the second
quarter of 1998. This decrease was primarily due to the Company's ability to
integrate new business acquisitions without a proportionate increase in general
and administrative expenses.

     INTEREST AND OTHER EXPENSES. Net interest and other expenses increased
$424,000, or 64.5%, from $657,000 for the quarter ended June 30, 1997 to $1.1
million for the quarter ended June 30, 1998. This increase resulted primarily
from interest expense incurred on borrowings used to fund the purchase price for
acquisitions completed in 1998.

     INCOME TAXES. The provision for income taxes increased $919,000, or 174.1%,
from $528,000 for the quarter ended June 30, 1997 to $1.4 million for the
quarter ended June 30, 1998 as a result of increased taxable income. The
effective tax rate for the period ended June 30, 1997 was 46.5% compared to a
41.0% rate for the period ended June 30, 1998.

SIX MONTHS ENDED JUNE 30, 1997 AND 1998

     REVENUES. Revenues for the six month period ended June 30, 1998 increased
$22.6 million, or 127.3%, from $17.7 million for the six months ended June 30,
1997 to $40.3 million for the six months ended June 30, 1998. The Industrial
Wastewater Division contributed $7.9 million, or 44.3%, of revenues for the

                                       13
<PAGE>
six months ended June 30, 1997 and $31.9 million, or 79.2%, of revenues for the
six months ended June 30, 1998. Tipping and collection fees generated $2.0
million, or 25.7%, and $22.4 million, or 70.3%, of the Industrial Wastewater
Division's revenues for the six month periods ended June 30, 1997 and 1998,
respectively. By-product sales generated the remaining $5.9 million, or 74.3%,
and $9.5 million, or 29.7%, of the Industrial Wastewater Division's revenues for
the 1997 and 1998 periods, respectively. The Oilfield Waste Division contributed
$9.9 million, or 55.7%, of revenues for the six month period ended June 30, 1997
and $8.4 million, or 20.8%, of revenues for the six month period ended June 30,
1998.

    The revenues of the Industrial Wastewater Division increased $24.1 million,
or 306.2%, from $7.9 million for the six months ended June 30, 1997 to $31.9
million for the six months ended June 30, 1998. This increase was due primarily
to acquisitions completed during the fourth quarter of 1997 and the first six
months of 1998 and an increase in the volume of waste processed resulting
primarily from the enactment of state-wide "full-pump" regulations in Texas. The
Oilfield Waste Division's revenues decreased $1.5 million, or 15.0%, from $9.9
million for the six months ended June 30, 1997 to $8.4 million for the six
months ended June 30, 1998. This decrease resulted primarily from lower receipts
of oilfield waste from Newpark under the Disposal Agreement. Newpark delivered
approximately 879,500 and 450,700 barrels of oilfield waste (excluding
saltwater) to the Company's landfarms during the six month periods ended June
30, 1997 and 1998, respectively.

     OPERATING EXPENSES. Operating expenses increased $14.8 million, or 145.7%,
from $10.1 million for the six months ended June 30, 1997 to $24.9 million for
the six months ended June 30, 1998. As a percentage of revenues, operating
expenses increased from 57.2% for the six month period ended June 30, 1997 to
61.8% for the six month period ended June 30, 1998. This increase was due
principally to the Company's transition from operating primarily as an oilfield
waste disposal company into an integrated liquid waste management company
providing collection, processing, recovery and disposal services.

     DEPRECIATION AND AMORTIZATION. Depreciation and amortization expenses
increased $1.8 million, or 137.5%, from $1.3 million for the six months ended
June 30, 1997 to $3.0 million for the six months ended June 30, 1998. As a
percentage of revenues, depreciation and amortization expenses increased
slightly from 7.2% for the six month period ended June 30, 1997 to 7.5% for the
six month period ended June 30, 1998.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased $2.6 million, or 115.9%, from $2.3 million for
the six months ended June 30, 1997 to $4.9 million for the six months ended June
30, 1998. As a percentage of revenues, selling, general and administrative
expenses decreased from 12.7% for the six month period ended June 30, 1997 to
12.1% for the six month period ended June 30, 1998. This improvement resulted
primarily from the Company's ability to integrate new business acquisitions
without a proportionate increase in general and administrative expenses.

     INTEREST AND OTHER EXPENSES. Net interest and other expenses increased
$285,000, or 25.1%, from $1.1 million for the six months ended June 30, 1997 to
$1.4 million for the six months ended June 30, 1998. This increase resulted
primarily from interest expense incurred on borrowings used to fund the purchase
price for acquisitions completed in 1998.

     INCOME TAXES. The provision for income taxes increased $1.4 million, or
137.1%, from $1.0 million for the six months ended June 30, 1997 to $2.4 million
for the six months ended June 30, 1998 as a result of increased taxable income.
The effective tax rate for the six months ended June 30, 1997 was 41%, compared
to a 40.4% rate for the six months ended June 30, 1998.

LIQUIDITY AND CAPITAL RESOURCES

    In June 1998, the Company completed a secondary offering of 3,450,000 shares
of common stock, resulting in net proceeds of approximately $60.9 million. The
net proceeds were applied against the outstanding balance of the Company's
Credit Facility, the vast majority of which indebtedness was incurred in
connection with acquisitions previously consummated by the Company.

    The Company had net working capital of $9.6 million at June 30, 1998,
compared to net working capital of $2.1 million at December 31, 1997.
Improvement in the working capital position was attributable primarily to an
increase in cash resulting from the exercise in late June of an over-allotment
option granted to the underwriters of the Company's secondary offering.

    The Company's capital requirements for its continuing operations consist of
its general working capital needs, scheduled principal payments on its debt
obligations and capital leases, and planned capital expenditures. At June 30,
1998, approximately $1.9 million of principal payments on debt obligations were
payable during the next twelve months. Capital expenditures during the three
months and the six months ended June 30, 1998 were $3.0 million and $4.3
million, respectively. The majority of the capital expenditures were for plant
expansions, equipment and vehicle upgrades. Capital expenditures for the last
two quarters of 1998 are budgeted at approximately $11.0 million. Of this
amount, approximately $1.8 million is budgeted to be invested in the Oilfield
Waste Division on equipment replacements and landfarm expansions. The remaining
amount is budgeted to be invested in the Industrial Wastewater Division for
plant expansions, equipment and vehicle upgrades.

    At June 30, 1998, the Company had established a $6.2 million reserve to
provide for the cost of future closures of facilities. The amount of this
unfunded reserve is based on the estimated total cost to the Company of closing
the facilities as calculated in accordance with the applicable regulations.
Applicable regulatory agencies require the Company to post financial assurance
with the agencies to assure that all waste will be treated and the facilities
closed appropriately. The Company has in place a total of $12.2 million of
financial assurance in the form of letters of credit and bonds.

    The Company has a $100 million credit facility (the "Credit Facility") with
a group of banks under which the Company may borrow to fund working capital
requirements and acquisitions. Amounts outstanding under the Credit Facility are
secured by, among other things, a lien on all or substantially all of the
Company's assets. The Credit Facility prohibits the payment of dividends and
requires the Company to comply with certain financial covenants. The Credit
Facility also places certain restrictions on, among other things, acquisitions
and other business combination transactions which may be consummated by the
Company. The Company does not believe that these restrictions will have a
material adverse effect on the Company's ability to fulfill its current
acquisition program. The debt outstanding under the Credit Facility may be
accelerated at the option of the lenders in the event that, among other things,
a change in control of the Company occurs or Michael P. Lawlor, W. Gregory Orr
or Earl J. Blackwell ceases to serve as an executive officer of the Company and
is not replaced within sixty days by an individual reasonably satisfactory to
the lenders. At June 30, 1998, the Company had borrowed approximately $38.0
million under the Credit Facility.

    The Company's capital resources consist of cash reserves, cash generated
from operations and funds available under the Credit Facility. The Company
expects that these resources will be sufficient to fund continuing operations
for at least the next twelve months. In addition to capital required for its
ongoing operations, the Company will require additional capital to pursue its
acquisition program. The Company anticipates that future acquisitions will be
made using a combination of common stock and cash, much of which is expected to
be derived from borrowings under the Credit Facility. In addition, the Company
may seek to raise additional equity capital for all or a substantial part of the
consideration to be paid for future

                                       15
<PAGE>
acquisitions or to reduce its debt. In the event that the common stock does not
maintain a sufficient market value or potential acquisition candidates are
unwilling to accept common stock as part of the consideration for the sale of
their businesses, the Company would be required to utilize more of its cash
resources in order to continue its acquisition program. At the same time, the
Company may be unable to raise additional capital due to market conditions. As a
result, the timing of acquisitions over the longer term can be expected to be
affected by prevailing market conditions. In addition, if the Company were
unable to secure the capital necessary to carry out its acquisition program, the
implementation of the Company's growth strategy would be adversely affected.

ACQUISITIONS

    During the three months ended June 30, 1998, the Company acquired or
contracted to acquire thirteen businesses, which collectively had 1997 revenues
of approximately $115.7 million. All of these acquisitions were consummated
during the three months ended June 30, 1998 except for the acquisition from USA
Waste of one business in Florida with approximately $6.6 million in 1997
revenues (the "Universal Waste Acquisition"), which was consummated on August 1,
1998. Pending the consummation of the Universal Waste Acquisition, USA Waste
operated the business on terms that had the same effect on the Company's
financial condition and results of operations as if the acquisition had been
consummated on May 1, 1998. Each of the acquisitions has been accounted for
under the purchase method of accounting. The total consideration for these
thirteen acquisitions (including the Universal Waste Acquisition) involved
approximately $64.1 million in cash and debt issued and 1,169,181 shares of the
Company's common stock. In addition, one acquisition provides for additional
payments of approximately $15,004,000 in connection with a five-year disposal
agreement entered into with the seller, which the Company has accrued for as a
contract reserve. In certain transactions, the Company agreed to issue
additional shares of common stock or make additional payments of cash to the
sellers upon the achievement by the acquired businesses of certain negotiated
goals, such as targeted earnings levels, or upon the occurrence of other
specified events.

    Since June 30, 1998, the Company has acquired four additional businesses,
which collectively had 1997 revenues of approximately $1.5 million. Each of
these acquisitions has been accounted for under the purchase method of
accounting. The total consideration for these four acquisitions involved
approximately $1.9 million in cash and assumed debt and 7,786 shares of the
Company's common stock. In two of these acquisitions, the Company agreed to make
additional payments of cash to the sellers upon the achievement by the acquired
businesses of targeted earnings levels.

YEAR 2000 COMPLIANCE

    Many existing computer programs use only two digits to identify a year in
the date field. These programs were designed and developed without considering
the impact of the upcoming change in the century. If not corrected, such
computer applications could fail or create erroneous results by or at the Year
2000. The Company has determined that its computer programs are Year 2000
compliant. When the Company completes an acquisition, it replaces the acquired
company's system with its own management and reporting and control systems.
Accordingly, the Company does not believe that its acquisition program will be
adversely affected by Year 2000 compliance issues.

PART II-OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

    On August 7, 1998, the Company settled substantially all of the claims
asserted against it in the three previously reported lawsuits relating to its
Bourg, Louisiana landfarm and a fourth lawsuit filed against the Company in July
1998 seeking injunctive relief against certain operations of the Bourg,
Louisiana landfarm. Under the terms of the settlement, the Company agreed to
expand the buffer zone along the western boundary of its landfarm. In addition,
the Company agreed to construct a berm along the property line closest to the
residences of the plaintiffs. The costs of these actions had previously been
reserved for by the Company and, thus, did not have any impact on earnings. This
settlement does not resolve certain claims asserted against the Company by
Acadian Shipyard, Inc., a local barge company ("Acadian"), in the FRILOUX ET AL.
V. CAMPBELL WELLS CORPORATION case pending in the 17th Judicial District Court
for the Parish of Lafourche, Louisiana. In the FRILOUX case, the Company has
asserted claims for indemnity and/or contribution against Acadian. Thereafter,
in July 1998, Acadian filed various counterclaims against the Company including,
without limitation, claims for defamation of business reputation and conspiracy
to damage Acadian's business reputation. In addition, Acadian requested
unspecified monetary damages allegedly suffered as a result of alleged
environmental contamination in connection with the ongoing operations at the
Bourg, Louisiana landfarm. The Company denies that it has any liability to
Acadian and intends to vigorously defend itself against these claims. In
addition, this settlement does not resolve the claims asserted in the class
action filed in the Civil District Court for the Parish of Orleans, Louisiana
seeking unspecified monetary damages allegedly suffered as a result of alleged
air, water and soil contamination in connection with ongoing operations at the
Company's Mermentau, Louisiana landfarm. The Company has not been named as a
defendant in this class action; however, there can be no assurance that the
Company will not subsequently be named as a defendant.

    In July 1998, the Company commenced an arbitration proceeding against
Newpark Resources, Inc. for failing to satisfy its delivery and payment
obligations under the Disposal Agreement. Specifically, the Company has alleged
that Newpark has fallen short of its delivery obligations under the Disposal
Agreement by approximately 635,000 barrels of oilfield waste valued at
approximately $3.5 million. The Company has requested that the arbitrators enter
an order (i) declaring that Newpark has breached the Disposal Agreement and no
condition existed or exists which would excuse Newpark's breach and (ii)
awarding the Company approximately $3.5 million in damages. The arbitrators for
the arbitration proceeding have not yet been selected and, thus, Newpark has not
responded to the claims asserted by the Company.

    The Company is, from time to time, a party to litigation arising in the
normal course of its business, most of which involves claims for personal injury
or property damage incurred in connection with its operations. Except as
described above, the Company is not currently involved in any litigation that it
believes will have a material adverse effect on its business, results of
operations or financial condition.

                            STOCK PURCHASE AGREEMENT

            THIS STOCK PURCHASE AGREEMENT (the "Agreement"), executed and
delivered as of June 25, 1998, among U S LIQUIDS, INC., a Delaware corporation
("Buyer"); MCS TRANSPORTATION, INC., a Texas corporation ("Company"); and
CHARLES C. STOUT, CHARLOTTE S. LYNCH, JAMES SCOTT RAINEY, DANNY C. HAMMOND,
THOMAS E. STARUSTKA, BRENDA B. SAVELL, JANICE S. WHALEN and JOHN DWIGHT ASKEW,
the sole stockholders ("Stockholders") of Company;

                            W I T N E S S E T H :

            WHEREAS, Company operates a commercial waste transportation business
in the San Leon, Texas, area (the "Business");

            WHEREAS, Company owns approximately three acres of real property
located in San Leon, Texas (the "Owned Land");

            WHEREAS, Company also leases approximately 5 acres of real property

lease dated February 14, 1995 (the "MCS Lease");

            WHEREAS, Stockholders own all of the issued and outstanding shares
of the capital stock of Company; and

            WHEREAS, Buyer desires to acquire all of the issued and outstanding
shares of the capital stock of Company from Stockholders and Stockholders desire
to sell such Company stock to Buyer as set forth herein;

            NOW, THEREFORE, in consideration of the premises and of the mutual
agreements, representations, warranties and obligations herein contained, the
parties hereby agree as follows:

1. DELIVERY OF SHARES; ENDORSEMENT OF COMPANY STOCK.

1.1 DELIVERY OF SHARES.

        Upon the terms and subject to the conditions set forth in this
Agreement, Stockholders shall, at the Closing (hereinafter defined), deliver to
Buyer certificates representing the number of shares set forth opposite each
Stockholders' name on Annex I attached hereto and made a part hereof, which
certificates represent all of the issued and outstanding capital stock of
Company (the "Company Stock"). Stockholders shall deliver the Company Stock to
Buyer free and clear of all liens, security interests, encumbrances, adverse
claims, pledges, charges, voting trusts, equities and other restrictions on
transfer of any nature whatsoever (collectively, "Adverse Claims"). 

1.2 ENDORSEMENT OF COMPANY STOCK.

        Stockholders shall deliver at Closing the certificates representing the
Company Stock, duly endorsed in blank by Stockholders or accompanied by stock
powers duly 

                                     Page 1
<PAGE>
endorsed in blank and with all necessary transfer tax and other
revenue stamps, acquired at Stockholders' expense, affixed and cancelled.
Stockholders, at their sole expense, agree to cure (both before and after
Closing) any deficiencies with respect to the endorsement of the certificates or
other documents of conveyance with respect to the Company Stock or with respect
to the stock powers accompanying the Company Stock.

2. PURCHASE PRICE.

2.1 PURCHASE PRICE.

        Subject to Sections 2.3 and 2.4 below, in consideration of the sale to
Buyer in accordance with this Agreement of the certificates representing the
Company Stock, Company shall pay to Stockholders on the Closing Date an
aggregate of: (a) $1,800,000 in immediately available funds; (b) that total
number of shares of the common stock of Buyer (the "Buyer Stock"), which shall
have an Agreed Value (hereinafter defined) equal to $1,400,000, all of which
will be contractually restricted for a period of one year in accordance with
Article 15 hereof; and (c) that total number of shares of Buyer Stock which
shall have an Agreed Value equal to $1,400,000, all of which will be
contractually restricted for a period of two years in accordance with Article 15
hereof. The consideration set forth in this Section 2.1 shall be allocated among
the Stockholders as set forth on Annex II attached hereto and made a part
hereof. 

2.2 AGREED VALUE OF BUYER STOCK.

        For purposes of this Agreement, the "Agreed Value" per share of Buyer
Stock shall be the average of the closing prices of a share of the common stock
of Buyer, $.01 par value per share, on the American Stock Exchange as reported
in THE WALL STREET JOURNAL for a period of five consecutive trading days. The
days used to obtain the average will be the tenth trading day through the sixth
trading day before the date of Closing.

2.3 ASSUMPTION OF DEBT.

        Attached hereto as Schedule 2.3 is a listing of all of the actual
long-term debt of Company (including the current portion of such debt) plus all
lease debt (including lease-end buyout payments) (the "Assumed Debt") and
evidence establishing the Assumed Debt. If the Assumed Debt of Company (when
combined with the actual long-term debt of Advanced Management Systems, Inc.
("AMS") is less than $435,000 on the Closing Date, the consideration payable in
Section 2.1(a) shall be increased by an amount equal to the difference between
$435,000 and the Assumed Debt of Company and AMS combined. If the Assumed Debt
of Company and AMS combined is more than $435,000 on the Closing Date, the
consideration payable in Section 2.1(a) shall be reduced by an amount equal to
the difference between $435,000 and the Assumed Debt of Company and AMS
combined. 

2.4 ADJUSTMENT TO CONSIDERATION.

        The parties agree that the consideration set forth in Section 2.1 was
determined as if the combined net working capital of Company and AMS was going
to be $1.00 at the close of business on the Closing Date. Accordingly, the
parties agree that the consideration set forth in Section 2.1(a) shall be
adjusted on the Adjustment Date to reflect the actual combined net working
capital 

                                     Page 2
<PAGE>
of Company and AMS on the Closing Date (the "Actual Net Working Capital"), as
shown on the balance sheet to be prepared in accordance with Section 10.2
hereof. If the Actual Net Working Capital so reflected is greater than $1.00 on
the Closing Date, then the consideration paid pursuant to Section 2.1(a) shall
be increased dollar for dollar for each dollar the Actual Net Working Capital
exceeds $1.00 on the Closing Date. If the Actual Net Working Capital so
reflected is less than $1.00 on the Closing Date, then the consideration paid
pursuant to Section 2.1(a) shall be decreased dollar for dollar for each dollar
the Actual Net Working Capital falls below $1.00 on the Closing Date. For
purposes of this Agreement, Actual Net Working Capital shall mean the combined
current assets of Company and AMS on the Closing Date minus all combined current
liabilities of Company and AMS on the Closing Date, calculated in accordance
with generally accepted accounting principles ("GAAP").

      In order to facilitate the contemplated adjustment to purchase price on
the Adjustment Date, between the date hereof and the Closing Date the parties
will prepare and agree upon an estimated combined net working capital balance
for Company and AMS as of May 31, 1998 (the "Estimated Working Capital").

      In the event of a dispute between the parties as to the Actual Net Working
Capital, the parties will have 30 days to resolve the dispute among themselves.
If the parties have not resolved such dispute within such 30-day period, then
the parties shall select an arbitrator who shall decide the dispute within 30
days after being selected. If the parties cannot agree on an arbitrator, then
Buyer and Stockholders shall each select an arbitrator and the two arbitrators
so selected shall select a third arbitrator. The parties hereto each agree to be
bound by the decision of the arbitrator(s). In the event that three arbitrators
are chosen, a majority decision will be required. Each arbitrator can be any
natural person above the age of 18 and need not have any specific qualification.
All costs of the arbitration shall be split 50/50 between Buyer and Stockholders
(as a group).

3. TITLE ASSURANCE.

3.1 TITLE POLICIES.

        Within 30 days after the Closing Date, Stockholders shall furnish to
Buyer extended coverage policies of title insurance from a title company
mutually acceptable to Buyer and Stockholders (the "Title Company") in an
aggregate amount mutually acceptable to Buyer and Stockholders with each of the
Title Company's standard printed exceptions deleted, insuring title to the
Leased Land and Owned Land to be in Company subject only to the exceptions
permitted by Section 3.2 hereof (the "Title Policies"). Stockholders shall
deliver to Buyer preliminary title commitments in respect of the Leased Land and
Owned Land, together with copies of all exception instruments referenced
therein, and any unrecorded leases, option agreements, contracts and any other
items affecting title which are in the possession of, or known to, Stockholders.

                                     Page 3
<PAGE>
3.2 PERMITTED ENCUMBRANCES.

        The Title Policies shall insure the interest of Company in the Leased
Land and Owned Land to be free and clear of all encumbrances whatsoever except:
(a) zoning ordinances and regulations which do not, in Buyer's judgment,
adversely affect continued use of the Leased Land and Owned Land for its current
uses after the Closing; (b) real estate taxes and assessments, both general and
special, which are a lien but are not yet due and payable at the Closing Date;
(b) easements, encumbrances, covenants, conditions, reservations and
restrictions of record, if any, as have been approved in writing by Buyer; and
(d) the MCS Lease. Stockholders shall pay all of the costs associated with the
delivery of the Title Policy.

3.3 SURVEY.

        Within 30 days after the Closing Date, Stockholders shall obtain for
Buyer's use and for the use of the Title Company in connection with the issuance
of the Title Policies a current and complete survey of the Owned Land, made on
the ground by a competent registered surveyor, showing for each: (a) the exact
boundary lines of the Owned Land; (b) the location thereon of all, if any,
buildings, improvements, and easements now existing; (c) the number of acres in
the Owned Land; (d) the location of any buildings, fences or other improvements
which encroach on the Owned Land; (e) the location of any improvements on the
Owned Land which encroach on any neighboring property or on any property which
is subject to any easement or right-of-way; (f) all building lines established
in respect of the Owned Land; and (g) all public access to the Owned Land, and
representing that the boundaries of the Owned Land are contiguous with the
boundaries of all adjoining parcels (together, the "Survey"). A copy of the
Survey complying with the above requirements shall be delivered to Buyer and the
Title Company, together with certification to each entity by the surveyor and
with such additional supporting reports and other certificates as the Title
Company may require to enable the Title Company to delete its standard survey
exceptions from the Title Policies. Stockholders shall pay all of the costs of
the Survey. 

4. CLOSING.

        Unless the parties agree otherwise, the closing of the within
contemplated transaction (the "Closing") shall take place on a date mutually
agreeable to Stockholders and Buyer within five business days after the
completion, satisfaction or waiver of each of the conditions to Closing set
forth in Articles 8 and 9. The Closing shall take place at a place mutually
agreeable to Buyer and Stockholders. The date on which the Closing occurs shall
be referred to as the "Closing Date."

5. REPRESENTATIONS AND WARRANTIES OF STOCKHOLDERS AND COMPANY.

        Company, as to the time period before Closing only, and each
Stockholder, jointly and severally, represents and warrants to Buyer that the
statements contained in this Section 5, except as set forth in the schedules to
the subsections of this Section 5 delivered by Stockholders to Buyer on the date
hereof (such schedules hereinafter collectively referred to as the "Disclosure
Schedules" and, individually, as a "Disclosure Schedule"): (i) are correct and
complete as of the date of this Agreement; (ii) will be correct and complete as
of the Closing Date 

                                     Page 4
<PAGE>
(as though made then and as though the Closing Date were substituted for the
date of this Agreement throughout this Section 5); and (iii) shall survive the
Closing. Nothing in the Disclosure Schedules shall be deemed adequate to
disclose an exception to a representation or warranty made herein, however,
unless the Disclosure Schedule identifies the exception with particularity and
describes the relevant facts in detail. Without limiting the generality of the
foregoing, the mere listing (or inclusion of a copy) of a document or other item
shall not be deemed adequate to disclose an exception to a representation or
warranty made herein (unless the representation or warranty has to do with the
existence of a document or other item itself).

12.2 INDEMNIFICATION BY BUYER.

        Buyer agrees that it will indemnify, defend, protect and hold harmless

<PAGE>
and (iii) any claim by a third party that, if true, would mean that a condition
for indemnification set forth in subsections (i) or (ii) of this Section 12.2
had been satisfied.

12.3 PROCEDURE FOR INDEMNIFICATION WITH RESPECT TO THIRD PARTY CLAIMS.

                (a) If any third party shall notify a party to this Agreement
        (the "Indemnified Party") with respect to any matter (a "Third Party
        Claim") that may give rise to a claim for indemnification against any
        other party to this Agreement (the "Indemnifying Party") or if any party
        who may make a claim for indemnification under this Agreement otherwise
        becomes aware of any matter that may give rise to such a claim or wishes
        to make such a claim (whether or not related to a Third Party Claim),
        then the Indemnified Party shall promptly notify each Indemnifying Party
        thereof in writing; provided, however, that no delay on the part of the
        Indemnified Party in notifying any Indemnifying Party shall relieve the
        Indemnifying Party from any obligation hereunder unless (and then solely
        to the extent) the Indemnifying Party is thereby prejudiced.

                (b) Any Indemnifying Party will have the right to defend the
        Indemnified Party against a Third Party Claim with counsel of its choice
        satisfactory to the Indemnified Party so long as (i) the Indemnifying
        Party notifies the Indemnified Party in writing within a reasonable time
        after the Indemnified Party has given notice of the Third Party Claim
        that the Indemnifying Party will indemnify the Indemnified Party from
        and against the entirety of any adverse consequences (which will
        include, without limitation, all losses, claims, liens, and attorneys'
        fees and related expenses) the Indemnified Party may suffer resulting
        from, arising out of, relating to, in the nature of, or caused by the
        Third Party Claim, (ii) the Indemnifying Party provides the Indemnified
        Party with evidence acceptable to the Indemnified Party that the
        Indemnifying Party will have the financial resources to defend against
        the Third Party Claim and fulfill its indemnification obligations
        hereunder, (iii) the Third Party Claim involves only monetary damages
        and does not seek an injunction or equitable relief or involve the
        possibility of criminal penalties, (iv) settlement of, or adverse
        judgment with respect to the Third Party Claim is not, in the good faith
        judgment of the Indemnified Party, likely to establish a precedential
        custom or practice adverse to the continuing business interests of the
        Indemnified Party, and (v) the Indemnifying Party conducts the defense
        of the Third Party Claim actively and diligently. 

                (c) So long as the Indemnifying Party is conducting the defense
        of the Third Party Claim in accordance with Section 12.3(b) above, (i)
        the Indemnified Party may retain separate co-counsel at its sole cost
        and expense and participate in the defense of the Third Party Claim,
        (ii) the Indemnified Party will not consent to the entry of any judgment

                                    Page 26
<PAGE>
        or enter into any settlement with respect to the Third Party Claim
        without the prior written consent of the Indemnifying Party (which will
        not be unreasonably withheld) and (iii) the Indemnifying Party will not
        consent to the entry of any judgment or enter into any settlement with
        respect to the Third Party Claim without the prior written consent of
        the Indemnified Party (which will not be unreasonably withheld). 

                (d) In the event or to the extent that any of the conditions set
        forth in Section 12.3(b) above is or becomes unsatisfied, however, (i)
        the Indemnified Party may defend against, and consent to the entry of
        any judgment or enter into any settlement with respect to, the Third
        Party Claim and any matter it may deem appropriate in its sole
        discretion and the Indemnified Party need not consult with, or obtain
        any consent from, any Indemnifying Party in connection therewith (but
        will keep the Indemnifying Party reasonably informed regarding the
        progress and anticipated cost thereof), (ii) the Indemnifying Party will
        reimburse the Indemnified Party promptly and periodically for the cost
        of defending against the Third Party Claim (including attorneys' fees
        and expenses) and (iii) the Indemnifying Party will remain responsible
        for any adverse consequences the Indemnified Party may suffer resulting
        from, arising out of, relating to, in the nature of, or caused by the
        Third Party Claim to the fullest extent provided in this Section 12; and
        (iv) the Indemnifying Party shall be deemed to have waived any claim
        that its indemnification obligation should be reduced because of the
        manner in which the counsel for the Indemnified Party handled the Third
        Party Claim.

shall not constitute a part of this Agreement or be used to construe or
interpret any provision hereof. 

16.11 SEVERABILITY.

way be affected or impaired thereby.

acquiring Company by merger, consolidation or other combination or acquiring any
of Company's assets; nor will any Stockholder permit Company to do any of the
foregoing.

      IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of

     THIS STOCK PURCHASE AGREEMENT (the "Agreement"), executed and delivered as
of June 25, 1998, among U S LIQUIDS, INC., a Delaware corporation ("Buyer");
ADVANCED MANAGEMENT SYSTEMS, INC., a Texas corporation ("Company"); and CHARLES
C. STOUT, the sole stockholder ("Stockholder") of Company;

                            W I T N E S S E T H :

     WHEREAS, Company operates a business which provides industrial field
services, hazardous and non-hazardous waste identification and manifesting and

     WHEREAS, in connection with the Business AMS leases office space in

Inc., a separate company owned by Stockholder (the "AMS Lease");

     WHEREAS, Stockholder owns all of the issued and outstanding shares of the
capital stock of Company; and

     WHEREAS, Buyer desires to acquire all of the issued and outstanding shares
of the capital stock of Company from Stockholder and Stockholder desires to sell
such Company stock to Buyer as set forth herein;

     NOW, THEREFORE, in consideration of the premises and of the mutual
agreements, representations, warranties and obligations herein contained, the
parties hereby agree as follows:

1. DELIVERY OF SHARES; ENDORSEMENT OF COMPANY STOCK.

1.1 DELIVERY OF SHARES.

     Upon the terms and subject to the conditions set forth in this Agreement,
Stockholder shall, at the Closing (hereinafter defined), deliver to Buyer
certificates representing the number of shares of stock of Company owned by
Stockholder, which certificates represent all of the issued and outstanding
capital stock of Company (the "Company Stock"). Stockholder shall deliver the
Company Stock to Buyer free and clear of all liens, security interests,
encumbrances, adverse claims, pledges, charges, voting trusts, equities and
other restrictions on transfer of any nature whatsoever (collectively, "Adverse
Claims"). 

1.2 ENDORSEMENT OF COMPANY STOCK.

     Stockholder shall deliver at Closing the certificates representing the
Company Stock, duly endorsed in blank by Stockholder or accompanied by stock
powers duly endorsed in blank and with all necessary transfer tax and other
revenue stamps, acquired at Stockholder's expense, affixed and cancelled.
Stockholder, at his sole expense, agrees to cure (both before and after Closing)
any deficiencies with respect to the endorsement of the certificates or other
documents of 

                                     Page 1
<PAGE>
conveyance with respect to the Company Stock or with respect to the stock powers
accompanying the Company Stock.

2. PURCHASE PRICE.

2.1 PURCHASE PRICE. 

     Subject to Sections 2.3 and 2.4 below, in consideration of the sale to
Buyer in accordance with this Agreement of the certificates representing the
Company Stock, Company shall pay to Stockholder on the Closing Date: (a)
$1,100,000 in immediately available funds; (b) that total number of shares of
the common stock of Buyer (the "Buyer Stock"), which shall have an Agreed Value
(hereinafter defined) equal to $50,000, all of which will be contractually
restricted for a period of one year in accordance with Article 15 hereof; and
(c) that total number of shares of Buyer Stock which shall have an Agreed Value
equal to $50,000, all of which will be contractually restricted for a period of
two years in accordance with Article 15 hereof.

2.2 Agreed Value of Buyer Stock.

     For purposes of this Agreement, the "Agreed Value" per share of Buyer Stock
shall be the average of the closing prices of a share of the common stock of
Buyer, $.01 par value per share, on the American Stock Exchange as reported in
The Wall Street Journal for a period of five consecutive trading days. The days
used to obtain the average will be the tenth trading day through the sixth
trading day before the date of Closing.

2.3 Assumption of Debt.

     Attached hereto as Schedule 2.3 is a listing of all of the actual long-term
debt of Company (including the current portion of such debt) plus all lease debt
(including lease-end buyout payments) (the "Assumed Debt") and evidence
establishing the Assumed Debt. If the Assumed Debt of Company (when combined
with the actual long term debt of MCS Transportation, Inc. ("MCS")) is less than
$435,000 on the Closing Date, the consideration payable in Section 2.1(a) shall
be increased by an amount equal to the difference between $435,000 and the
Assumed Debt of Company and MCS combined. If the Assumed Debt of Company and MCS
combined is more than $435,000 on the Closing Date, the consideration payable in
Section 2.1(a) shall be reduced by an amount equal to the difference between
$435,000 and the Assumed Debt of Company and MCS combined. 

2.4 ADJUSTMENT TO CONSIDERATION.

     The parties agree that the consideration set forth in Section 2.1 was
determined as if the combined net working capital of Company and MCS was going
to be $1.00 at the close of business on the Closing Date. Accordingly, the
parties agree that the consideration set forth in Section 2.1(a) shall be
adjusted on the Adjustment Date to reflect the actual combined net working
capital of Company and MCS on the Closing Date (the "Actual Net Working
Capital"), as shown on the balance sheet to be prepared in accordance with
Section 10.2 hereof. If the Actual Net Working Capital so reflected is greater
than $1.00 on the Closing Date, then 


                                     Page 2
<PAGE>
the consideration paid pursuant to Section 2.1(a) shall be increased dollar for
dollar for each dollar the Actual Net Working Capital exceeds $1.00 on the
Closing Date. If the Actual Net Working Capital so reflected is less than $1.00
on the Closing Date, then the consideration paid pursuant to Section 2.1(a)
shall be decreased dollar for dollar for each dollar the Actual Net Working
Capital falls below $1.00 on the Closing Date. For purposes of this Agreement,
Actual Net Working Capital shall mean the combined current assets of Company and
MCS on the Closing Date minus all combined current liabilities of Company and
MCS on the Closing Date, calculated in accordance with generally accepted
accounting principles ("GAAP").

     In order to facilitate the contemplated adjustment to purchase price on the
Adjustment Date, between the date hereof and the Closing Date the parties will
prepare and agree upon an estimated combined net working capital balance for
Company and MCS as of May 31, 1998 (the "Estimated Working Capital").

     In the event of a dispute between the parties as to the Actual Net Working
Capital, the parties will have 30 days to resolve the dispute among themselves.
If the parties have not resolved such dispute within such 30-day period, then
the parties shall select an arbitrator who shall decide the dispute within 30
days after being selected. If the parties cannot agree on an arbitrator, then
Buyer and Stockholder shall each select an arbitrator and the two arbitrators so
selected shall select a third arbitrator. The parties hereto each agree to be
bound by the decision of the arbitrator(s). In the event that three arbitrators
are chosen, a majority decision will be required. Each arbitrator can be any
natural person above the age of 18 and need not have any specific qualification.
All costs of the arbitration shall be split equally between Buyer and
Stockholder.

3. TITLE ASSURANCE. INTENTIONALLY DELETED.

4. CLOSING.

     Unless the parties agree otherwise, the closing of the within contemplated
transaction (the "Closing") shall take place on a date mutually agreeable to
Stockholder and Buyer within five business days after the completion,
satisfaction or waiver of each of the conditions to Closing set forth in
Articles 8 and 9. The Closing shall take place at a place mutually agreeable to
Buyer and Stockholder. The date on which the Closing occurs shall be referred to
as the "Closing Date."

5. REPRESENTATIONS AND WARRANTIES OF STOCKHOLDER AND COMPANY.

     Company, as to the time period before Closing only, and Stockholder,
jointly and severally, represents and warrants to Buyer that the statements
contained in this Section 5, except as set forth in the schedules to the
subsections of this Section 5 delivered by Stockholder to Buyer on the date
hereof (such schedules hereinafter collectively referred to as the "Disclosure
Schedules" and, individually, as a "Disclosure Schedule"): (i) are correct and
complete as of the date of this Agreement; (ii) will be correct and complete as
of the Closing Date (as though made then and as though the Closing Date were
substituted for the date of this Agreement throughout this Section 5); and (iii)
shall survive the Closing. Nothing in the Disclosure Schedules shall be deemed
adequate to disclose an exception to a representation or warranty made herein,
however, unless the Disclosure Schedule identifies the exception with
particularity 

                                     Page 3
<PAGE>
and describes the relevant facts in detail. Without limiting the
generality of the foregoing, the mere listing (or inclusion of a copy) of a
document or other item shall not be deemed adequate to disclose an exception to
a representation or warranty made herein (unless the representation or warranty
has to do with the existence of a document or other item itself).

          Indemnifying Party shall relieve the Indemnifying Party from any
          obligation hereunder unless (and then solely to the extent) the
          Indemnifying Party is thereby prejudiced.

               (b) Any Indemnifying Party will have the right to defend the
          Indemnified Party against a Third Party Claim with counsel of its
          choice satisfactory to the Indemnified Party so long as (i) the
          Indemnifying Party notifies the Indemnified Party in writing within a
          reasonable time after the Indemnified Party has given notice of the
          Third Party Claim that the Indemnifying Party will indemnify the
          Indemnified Party from and against the entirety of any adverse
          consequences (which will include, without limitation, all losses,
          claims, liens, and attorneys' fees and related expenses) the
          Indemnified Party may suffer resulting from, arising out of, relating
          to, in the nature of, or caused by the Third Party Claim, (ii) the
          Indemnifying Party provides the Indemnified Party with evidence
          acceptable to the Indemnified Party that the Indemnifying Party will
          have the financial resources to defend against the Third Party Claim
          and fulfill its indemnification obligations hereunder, (iii) the Third
          Party Claim involves only monetary damages and does not seek an
          injunction or equitable relief or involve the possibility of criminal
          penalties, (iv) settlement of, or adverse judgment with respect to the
          Third Party Claim is not, in the good faith judgment of the
          Indemnified Party, likely to establish a precedential custom or
          practice adverse to the continuing business interests of the
          Indemnified Party, and (v) the Indemnifying Party conducts the defense
          of the Third Party Claim actively and diligently. 

               (c) So long as the Indemnifying Party is conducting the defense
          of the Third Party Claim in accordance with Section 12.3(b) above, (i)
          the Indemnified Party may retain separate co-counsel at its sole cost
          and expense and participate in the defense of the Third Party Claim,
          (ii) the Indemnified Party will not consent to the entry of any
          judgment or enter into any settlement with respect to the Third Party
          Claim without the prior written consent of the Indemnifying Party
          (which will not be unreasonably withheld) and (iii) the Indemnifying
          Party will not consent to the entry of any judgment or enter into any
          settlement with respect to the Third Party Claim without the prior
          written consent of the Indemnified Party (which will not be
          unreasonably withheld). 

               (d) In the event or to the extent that any of the conditions set
          forth in Section 12.3(b) above is or becomes unsatisfied, however, (i)
          the Indemnified Party may defend against, and consent to the entry of
          any judgment or enter into any settlement with respect to, the Third
          Party Claim and any matter it may deem appropriate in its sole
          discretion and the Indemnified Party need not consult with, or obtain
          any consent from, any Indemnifying Party in connection therewith (but
          will keep the Indemnifying Party reasonably informed regarding the
          progress and anticipated cost thereof), (ii) the Indemnifying Party
          will 

                                    Page 25
<PAGE>
          reimburse the Indemnified Party promptly and periodically for the cost
          of defending against the Third Party Claim (including attorneys' fees
          and expenses) and (iii) the Indemnifying Party will remain responsible
          for any adverse consequences the Indemnified Party may suffer
          resulting from, arising out of, relating to, in the nature of, or
          caused by the Third Party Claim to the fullest extent provided in this
          Section 12; and (iv) the Indemnifying Party shall be deemed to have
          waived any claim that its indemnification obligation should be reduced
          because of the manner in which the counsel for the Indemnified Party
          handled the Third Party Claim.

or in any similar breach or default occurring later; nor shall any waiver of any

16.9 TIME OF THE ESSENCE.

     Time is of the essence for this Agreement. 

16.10 CAPTIONS.

     The headings of this Agreement are inserted for convenience only and shall
not constitute a part of this Agreement or be used to construe or interpret any
provision hereof. 

16.11 SEVERABILITY.

     In case any provision of this Agreement shall be invalid, illegal or
unenforceable, it shall, to the extent possible, be modified in such manner as

severed from this Agreement. In either case the validity, legality and
enforceability of the remaining provisions of this Agreement shall not in any
way be affected or impaired thereby. 

16.12 CONSTRUCTION.

     The parties have participated jointly in the negotiation and drafting of
this Agreement. In the event an ambiguity or question of intent or
interpretation arises, this Agreement shall be construed as if drafted jointly
by the parties, and no presumption or burden of proof shall arise favoring or
disfavoring any party by virtue of the authorship of any of the provisions of
this Agreement. Any reference to any federal, state, local or foreign statute
shall be deemed to refer to all rules and regulations promulgated thereunder,
unless the context requires otherwise. The word "including" means 

                                    Page 30
<PAGE>
including, without limitation. The parties intend that representation, warranty
and covenant contained herein shall have independent significance. If any party
has breached any representation, warranty or covenant contained herein in any
respect, the fact that there exists another representation, warranty or covenant
relating to the same subject matter (regardless of the relative levels of
specificity) that the party has not breached shall not detract from or mitigate
the fact the party is in breach of the first representation, warranty or
covenant.

16.13 STANDSTILL AGREEMENT.

     Unless and until this Agreement is terminated pursuant to Article 13 hereof
without the Closing having taken place, Stockholder will not directly or
indirectly solicit offers for Company Stock or the assets of Company or a merger
or consolidation involving Company from, or respond to inquiries from, share
information with, negotiate with or in any way facilitate inquiries or offers
from, third parties who express or who have heretofore expressed an interest in
acquiring Company by merger, consolidation or other combination or acquiring any
of Company's assets; nor will he permit Company to do any of the foregoing.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the day and year first above written.
