             Notes to Consolidated Financial Statements (Unaudited)


NOTE 1 - BASIS OF PRESENTATION
------------------------------

The accompanying unaudited interim consolidated financial statements have been
prepared pursuant to the rules and regulations of the Securities and Exchange
Commission.  Accordingly, certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been omitted pursuant to such rules and regulations.
The accompanying unaudited interim consolidated financial statements and related
notes should be read in conjunction with the financial statements and related
notes included in the Company's 1996 Annual Report on Form 10-K.  In the opinion
of management, all material adjustments, consisting of normal recurring
adjustments, considered necessary for a fair presentation have been included in
the accompanying unaudited interim consolidated financial statements.  Operating
results for the six months ended March 31, 1997, are not necessarily indicative
of the results that may be expected for the year ending September 30, 1997.

NOTE 2 - ACQUISITION
--------------------

Effective September 30, 1996, the Company purchased the stock of Process
Equipment Division of Ingersoll-Rand Company ("CPM") for $60,868,697.  CPM, a
multi-national entity, is also engaged in the design and manufacture of process
equipment.  The acquisition was financed under a new $95 million credit
facility.  Additionally, subsequent to September 30, 1996, an equity infusion of
approximately $3,000,000 was provided by certain key members of operating
management.

The results of operations of CPM have been included in the results of the
Company from October 1, 1996.  Assuming the acquisition had occurred on October
1, 1995, the Company's (unaudited) net sales, net income, and earnings per share
would have been approximately $74,099,000, $1,440,000, and $0.65, respectively,
for the six months ended March 31, 1996 and approximately $39,696,000,
$1,208,000, and $0.55, respectively, for the three months ended March 31, 1996.

NOTE 3 - CASH DIVIDEND
----------------------

On November 21, 1996, the Company declared a cash dividend of $0.05 per share,
payable January 4, 1997, to shareholders of record as of December 18, 1996.

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

A.   Consolidated Results of Operations
     ----------------------------------

Results of operations for the quarter ended March 31, 1997, as compared to the
------------------------------------------------------------------------------
quarter ended March 31, 1996:
---------------------------- 

Total net revenue for the quarter ended March 31, 1997 was $48,717,000 versus
$17,433,000 for the same period of 1996, an increase of $31,284,000 or 179.45%.
The increase resulted primarily from the inclusion of sales from the newly
acquired subsidiary, CPM.

Production costs were $37,556,000 or 77.1% of net revenue in the second quarter
of fiscal 1997, versus $12,165,000 or 69.8% of net revenue in the same period in
fiscal 1996.  The increase in production cost dollars is a direct result of the
CPM acquisition.

Product engineering and development costs decreased $58,000 or 9.3% primarily as
a result of lower personnel costs.

Selling, general and administrative expenses increased in the second quarter of
fiscal 1997 to $6,063,000 from $2,274,000 in the same period of fiscal 1996 due
primarily to the CPM acquisition. Additionally, the amortization of goodwill and
deferred costs emanating from the acquisition also contributed to the increase.

The change in interest expense reflects higher average borrowings, primarily as
a result of financing the CPM acquisition.

Net income in the second quarter of fiscal 1996 amounted to $1,861,000, a
$611,000 increase over the second quarter of fiscal 1996 net income of
$1,250,000 as a result of the above factors.

Results of operations for the six months ended March 31, 1997, as compared to
-----------------------------------------------------------------------------
the six months ended March 31, 1996:
----------------------------------- 

Total net revenue for the six months ended March 31, 1997 was $83,936,000 versus
$25,694,000 for the same period of 1996, an increase of $58,242,000 or 226.7%.
The increase resulted primarily from the inclusion of sales from the newly
acquired subsidiary, CPM.

Production costs were $62,413,000 or 74.4% of net revenue in the first six
months of fiscal 1997 versus $18,654,000 or 72.6% of net revenue in the same
period in fiscal 1996.  The increase in production cost dollars is a direct
result of the CPM acquisition.

Selling, general, and administrative expenses increased in the first six months
of fiscal 1997 to $14,188,000 from $4,356,000 in the same period of fiscal 1996,
due primarily to the CPM acquisition.  Additionally, the amortization expense of
goodwill and deferred costs emanating from the acquisition also contributed to
the increase in costs.

The change in interest expense reflects higher average borrowings, primarily as
a result of financing the CPM acquisition.

Net income increased in the first six months of fiscal 1997 to $2,143,000 from
$577,000 in the first six months of fiscal 1996 as a result of the above
factors.

Liquidity and Capital Resources
-------------------------------

The Company had working capital at March 31, 1997 of $50,290,000 as compared
with working capital of $39,861,000 as of September 30, 1996.  The increase in
working capital resulted from an increase in cash, accounts receivable, and
inventory and a reduction in notes payable, partially offset by increases in
accounts payable and customer deposits.

The Company's asphalt production equipment operations are subject to seasonal
fluctuations, often resulting in lower sales in the first and fourth fiscal
quarters of each year and much lower earnings or losses during such quarters.
CPM's operations are subject to less seasonality, and the seasonality which does
occur is opposite that of the construction equipment operations.

During the six months ended March 31, 1997, the Company's total debt increased
$5,216,000 as a result of increased borrowings, partially offset by scheduled
principal repayments.

The Company believes that, based on the present conditions and banking
arrangements, it will be able to meet  its working capital needs during fiscal
1997 through operations.

B.   Financial Condition as of March 31, 1997
     ----------------------------------------

There are no material changes in the Company's financial condition from that
reported as of September 30, 1996.
