During September 2001, the Company's Swedish food processing operation was
placed into receivership and subsequently disposed of during the first quarter
of fiscal 2002. The Company provided a loss contingency for the net assets of
the Swedish operations during fiscal 2001. During the first quarter of fiscal
2002, the Company wrote off the remaining net assets of the Swedish operations
against the loss reserve.

Note 6 - Comprehensive Loss

Total comprehensive income was $894 and $2,268 for the three-and nine-months
ended June 30, 2002, respectively, and $10,435 and $8,160 for the same periods
ended June 30, 2001. Total comprehensive income differs from net income due to
gains and losses resulting from foreign currency translation, which are
reflected separately in the shareholders' equity section of the balance sheet
under the caption "Accumulated other comprehensive loss." Gains and losses
resulting from foreign currency transactions are included in income.

Note 7 - Income From Investees

During the first and second quarter of fiscal 2002, the Company received cash
distributions of $465 and $1,061, respectively, from its 45% interest in
Carbontronics LLC and 25% interest in Carbontronics II LLC and Carbontronics
Fuels LLC. These interests were obtained as part of contracts to build four
synthetic fuel production plants during 1998. The Company has no basis in these
investments nor requirement to provide future funding. Any income arising from
these investments is dependent upon tax credits (adjusted for operating losses
at the fuel plants) being generated as a result of synthetic fuel production,
which will be recorded as received. During fiscal 2001, the Company received one
distribution of approximately $215. No significant income was derived from these
interests during fiscal 2000 or fiscal 1999.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations

Results of Operations

Net sales for the nine-months ended June 30, 2002 and 2001 were $51.2 million
and $54.2 million, respectively. Domestic sales during this period for 2002 and
2001 were $32.8 million and $42.0 million, respectively. The decline in domestic
sales is primarily due to the stalling of our industry attributable to the
September 11 events and the prevailing national economic conditions. Asphalt
plant orders at the Company's U.K. operations increased $6.2 million from the
previous year, which partially offset the decline in domestic sales. Net sales
for the third quarter of 2002 declined by approximately $3.0 million from the
same period of fiscal 2001. Domestic sales during the quarter were lower by
approximately $7.0 million. Foreign sales increased by approximately $4.0
million over the same quarter of last year.

Gross margins as a percent of net sales declined by 3.4% during the nine-months
ended June 30, 2002 from year ago levels. Margins have declined due to a higher
mix of foreign versus domestic sales. In addition, domestic margins have
declined 5.4% from a year ago due to a higher mix of component sales as opposed
to complete plant sales. Gross margins on foreign sales increased 9.2% from a
year ago due to lower production costs.

Product engineering and development costs declined $151 and $431 during the
three- and nine-month periods ended June 2002. Selling and administrative
expenses decreased $591 and $1,428 during the three- and nine-month periods
ended June 2002. The improvements reflect cost reductions and containment
measures initiated by the Company during the first quarter of 2002.

Restructuring costs, which consist of legal and professional fees relating to
the reorganization were $302 during the first nine-months of fiscal 2002
compared to $3,060 for the same period of fiscal 2001.

Interest expense during 2002, primarily reflects interest incurred under the
Amended and Restated Senior Secured Credit Agreement since the Company emerged
from Chapter 11 at the end of the first quarter.

Income from investees includes cash distributions of $465 and $1,061 received
during the first and second quarter of 2002, respectively.

Net income for the quarter ended June 30, 2001 included $5.2 million from
discontinued operations, which includes a net gain on sale of the food
processing segment of $3.5 million.

Liquidity and Capital Resources

On December 27, 2001, the Company and its Senior Secured Lenders signed an
Amended and Restated Senior Secured Credit Agreement (Credit Agreement). The
Credit Agreement specifies monthly principal payments of $320 beginning December
2001 and continuing through July 2002, then increasing to $400 in August 2002
and continuing to August 2005, with the remaining balance due September 6, 2005.
It is management's intention to refinance any remaining balance. The interest
rate during the term of the loan is based upon the prime rate plus 2%. The
Company may elect to defer the first thirteen (13) monthly principal payments
and pay an additional 5% interest on the total deferred principal payments until
such time the deferred principal amounts are paid. The Credit Agreement also
provides for quarterly supplemental principal payments if certain operating
levels are surpassed. A supplemental principal payment for $710 was paid on May
17, 2002. Based upon the operating results for the third quarter, another
supplemental principal payment for approximately $256 will be due August 29,
2002. The Credit Agreement includes other financial and restrictive covenants.

                                       10

<PAGE>

Pursuant to its Amended Plan of Reorganization, on January 29, 2002 the Company
made a principal payment of $488 on the industrial revenue bond. Monthly
principal and interest payments of $38 will continue until the balance is
paid-off in March 2005.

The Company has been successful in its efforts to restructure or eliminate
various non-core operations and reduce its outstanding debt balance. As a
result, the Company's capital structure, liquidity and working capital have
significantly improved from a year ago. The current ratio of 1.59:1.00 and
working capital of $16.3 million at June 30, 2002 compares favorably to the
current ratio of .72:1.00 and negative working capital of $20.8 million a year
earlier.

Net cash used for operating activities during the nine-months ended June 30,
2002 was $515. This net cash outlay reflects a $4.3 million increase in accounts
receivable (attributable to several large plant orders), which was offset by a
$4.3 million decrease in inventories. Cash used in financing activities reflect
principal payments on the secured debt of $3.2 million.

Seasonality

The asphalt-related operations are subject to a seasonal slow-down during the
third and fourth quarters of the calendar year. Traditionally, although
customers may place orders for winter and spring deliveries, especially during
the fourth quarter, they do not accept delivery of new equipment during the
summer and fall months to avoid disrupting their peak activity of highway
construction and repair. This slow-down often results in lower reported sales
and earnings and or losses during the first and fourth quarters of the Company's
fiscal year ended September 30.

Forward-Looking Information

Certain statements in this Section and elsewhere in this report are
forward-looking in nature and relate to trends and events that may affect the
Company's future financial position and operating results. Such statements are
made pursuant to the safe harbor provisions of the Private Securities Litigation
Reform Act of 1995. The terms "expect," "anticipate," "believe," "intend," and
"project' and similar words or expressions are intended to identify
forward-looking statements. These statements speak only as of the date of this
report. The statements are based on current expectations, are inherently
uncertain, are subject to risks, and should be viewed with caution. Actual
results and experience may differ materially from the forward-looking statements
as a result of many factors, including changes in economic conditions in the
markets served by the Company, increasing competition, fluctuations in raw
materials and energy prices, and other unanticipated events and conditions. It
is not possible to foresee or identify all such factors. The Company makes no
commitment to update any forward-looking statement or to disclose any facts,
events, or circumstances after the date hereof that may affect the accuracy of
any forward-looking statement.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

The Company operates manufacturing facilities and sales offices principally
located in the United States and the United Kingdom. The Company is subject to
business risks inherent in non-U.S. activities, including political and economic
uncertainty, import and export limitations, and market risk related to changes
in interest rates and foreign currency exchange rates. The Company's principal
currency exposure against the U.S. dollar is the British pound. The Company is
exposed to interest rate risk on its variable rate debt. A 100-basis point
increase in interest rates along the entire yield curve would reduce income from
continuing operations before income taxes for the nine-month periods ended June
30, 2002 and 2001 by approximately $258 and $679, respectively. Actual changes
in rates may differ from the hypothetical assumptions used in computing this
exposure.
