4.       EXTRAORDINARY ITEM - EARLY EXTINGUISHMENT OF DEBT

         As a result of the early retirement of the Chemical Bank debt and the
partial payment on the CIT note, the Company recognized an extraordinary expense
of $93,000 (net of the related tax benefit of $54,000) for the write down of
deferred financing expenses related to these debts during the three months ended
February 29, 1996.

5.       EARNINGS PER SHARE

         Net earnings per share is computed using the weighted average number of
shares of common stock outstanding for the period. When dilutive, stock options
and warrants are included as share equivalents using the treasury stock method.
In calculating net earnings per share, preferred dividends of $24,718 and
$71,746 reduced the net earnings available to common stockholders for the three
months and nine months ended May 31, 1997, respectively. Fully diluted net
earnings per common share is not significantly different from primary net
earnings per common share.

6.       RECENT DEVELOPMENTS

         On April 30, 1997, the Company entered into an Agreement and Plan of
Merger (the "Merger Agreement") with Chart Industries, Inc. ("Chart") and
certain of Chart's wholly-owned subsidiaries pursuant to which the Company will
become an indirect, wholly-owned subsidiary of Chart (the "Merger"). As a result
of the Merger, each outstanding share of common stock of the Company will be
converted into the right to receive $2.75 in cash, without interest. The Merger

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

         This Quarterly Report on Form 10-Q contains certain forward-looking
statements that involve risks and uncertainties. Discussions containing such
forward-looking statements may be found in the materials set forth below in
"Management's Discussion and Analysis of Financial Condition and Results of
Operations." The Company's actual results could differ materially from those
anticipated in the forward-looking statements.

Results of Operations - Three and Nine
Months Ended May 31, 1996 and May 31, 1997

         Contract revenue decreased 6.7% to $7.7 million for the three months
ended May 31, 1997 from $8.2 million for the three months ended May 31, 1996.
Contract revenue for the first nine months of the 1997 fiscal year decreased
16.0% to $20.5 million from $24.4 million for the same period of the preceding
year. The quarterly decrease is the result of decreases in revenue from
industrial gas and LNG trailers, MRI cryostats and components, and LNG
dispensing equipment, which decreased $1.4 million, $834,000 and $141,000,
respectively, over the corresponding period in the prior year. The Company does
not believe that these decreases are indicative of a long-term trend. These
decreases were offset somewhat by increased revenues from TVAC'r' intermodal
containers which increased $1.7 million over the corresponding 1996 period. For
the nine month period the decrease was primarily the result of the decrease in
revenues from industrial gas and LNG trailers, MRI cryostats and components, and
LNG dispensing equipment, which decreased $4.5 million, $2.0 million and
$679,000, respectively, over the corresponding nine month period in the prior
year. These decreases were offset somewhat by increased revenues from TVAC'r'
intermodal containers and cryogenic spares, which increased $2.7 million and
$327,000, respectively, over the corresponding 1996 period.

         Gross profit for the three months ended May 31, 1997 decreased 30.4% to
$1.3 million, or 16.5% of contract revenue, from $1.8 million, or 22.2% of
contract revenue, for the three months ended May 31, 1996. Gross profit for the
first nine months of the 1997 fiscal year decreased 17.5% to $4.0 million, or
19.6% of contract revenue, from $4.9 million, or 20.0% of contract revenue, for
the same period of the previous year. The gross profit decrease for the quarter
was the result of the reduced revenues combined with lower sales prices on
trailers and unabsorbed manufacturing overhead expenses due to the reduced level
of shop activity. For the nine month period the decrease was primarily due to
the reduced revenues and increased unabsorbed manufacturing overhead expenses.

         Selling, general and administrative expenses increased $14.5% to $1.0
million for the three months ended May 31, 1997 from $894,000 for the three
months ended May 31, 1996, and increased as a percentage of contract revenue to
13.3% from 10.9% during the same period. Selling, general and administrative
expenses for the first nine months of fiscal 1997 increased 3.2% to $2.5 million
or 12.2% of contract revenue from $2.4 million or 10.0% of contract revenue
compared to the corresponding period in the prior year. The increase is
primarily due


                                       11









to the legal and consulting expenses related to the anticipated merger with
Chart Industries, Inc., and to a lesser extent is due to increased sales
expenses. Research and development costs decreased to $(14,000) for the three
months ended May 31, 1997 from $277,000 for the three months ended May 31, 1996,
and to $315,000 for the first nine months of fiscal 1997 compared to $708,000
for the comparable period of the prior year. The credit in the current period is
due to the timing of billings for the reimbursement of TADOPTR development costs
under a development contract. The decrease in expenses for both the three and
nine month periods is primarily the result of the decrease in expenditures for
the development of new LNG products compared to the prior year. Amortization
expense decreased to $59,000 for the three months ended May 31, 1997 from
$87,000 for the three months ended May 31, 1996, and to $181,000 for the first
nine months of fiscal 1997 compared to $259,000 for the comparable period of the
prior year due to the completion of the organization cost amortization in the
prior year.

         Interest expense for the three months ended May 31, 1997 increased 2.2%
to $231,000 from $226,000 for the three months ended May 31, 1996 and increased
8.4% to $722,000 for the first nine months of the 1997 fiscal year from $666,000
for the same period of the preceding year. This increase in the current quarter
is due to increased debt issuance cost amortization due to the repayment of the
balance of the subordinated debt during the quarter. The cumulative increase is
primarily due to an increased average level of borrowing. Other non-operating
items resulted in income of $213,000 for the three months ended May 31, 1997,
compared to an expense of $5,000 in the comparable period of 1996, and income of
$269,000 in the first nine months of this fiscal year compared to an expense of
$1,000 for the first nine months of the 1996 fiscal year. The increase in income
in the current period is the result of a gain on the sale of capital equipment.
In addition, the increase in income in the nine month period includes a $49,000
profit on the sale of the Company's interest in Applied LNG Technologies USA,
LLC.

         Income tax expense decreased to $68,000 for the three months ended May
31, 1997 from $126,000 for the three months ended May 31, 1996 and to $208,000
for the first nine months of this fiscal year from $300,000 for the first nine
months of the prior year. The expense in both years is the result of taxable
income for the periods and estimated annual tax rates.

         The resulting net income decreased to $116,000 for the three months
ended May 31, 1997 from $212,000 for the corresponding prior year period, and
decreased to $355,000 for the nine months ended May 31, 1997 from $510,000 for
the corresponding nine month period of the prior year. This change is the result
of the cumulative effect of the above factors.

Liquidity and Capital Resources

         At May 31, 1997, the Company's working capital was $9.7 million, which
represented a current ratio of 3.7 to 1. Also, the Company's outstanding
indebtedness under the Credit Agreement with FBS Business Finance Corporation
was $6.9 million, of which $499,000 represented term indebtedness and $6.4
million represented revolving indebtedness.


                                       12









         Cash flow from operations for the nine months ended May 31, 1997
resulted in cash provided in the amount of $2.8 million compared to cash used of
$1.3 million in the same period of the prior year. In the current year, cash was
provided primarily by the decreases in accounts receivable and by net income. In
the nine months ended May 31, 1996 cash was used to increase accounts
receivable, which was somewhat offset by the decrease in costs and estimated
earnings in excess of billings on uncompleted contracts and by net income.

         The Company believes that its existing capital resources, together with
cash flow from future operations will be sufficient to meet its short term
working capital needs. Additional financing may be required for future expansion
of operations.

Recent Developments

         On April 30, 1997, the Company entered into an Agreement and Plan of
Merger (the "Merger Agreement") with Chart Industries, Inc. ("Chart") and
certain of Chart's wholly-owned subsidiaries pursuant to which the Company will
become an indirect, wholly-owned subsidiary of Chart (the "Merger"). As a result
of the Merger, each outstanding share of common stock of the Company will be
converted into the right to receive $2.75 in cash, without interest. The Merger
Agreement and the Merger are subject to approval by the stockholders of the
Company. A Special Meeting of the Company's stockholders is scheduled for July
31, 1997 in order to vote upon approval and adoption of the Merger Agreement and
the transactions contemplated thereby.
