PART II - BRAD VETAL'S COMMENTS

[BRAD START HERE]

Turning to the quarter just ended, revenue for the fourth quarter advanced 11.8%
to $65.8 million from $58.9 million reported last year. Net income for the
fourth quarter totaled $1.9 million, or $0.22 per fully diluted share, versus
$2.1 million, or $0.27 per fully diluted share for the same period a year ago.
Compared to the fourth quarter in 2001, gross margins on a consolidated basis
were 11.9% versus 13.9%. The decline in profitability was anticipated and
primarily due to lower profitability in Plant Services as turnaround work was
very strong in the fourth quarter of last year compared to this year.

Net income for the full fiscal year 2002 climbed 28.4% to $5.9 million from $4.6
million for 2001. Fully diluted earnings per share increased 35.2% from $.54 per
share to $.73 per share and were in the middle of the guidance range provided by
management last quarter. For the year, consolidated revenues rose 16.6% to
$222.5 million from $190.9 million in the previous year, with increases in AST
Services and Construction Services offset somewhat by a $2.3 million decline in
Plant Services.

Consolidated gross margins for the full fiscal year were 11.4% compared to 11.8%
last year. The decline was attributable to the two large AST jobs that
experienced negative gross margins in the third quarter of fiscal 2002.

                                       -4-



We were very pleased with the performance at the Construction Services Division
where revenues and gross margins increased significantly. The refocus on the
capital work from our core client base has resulted in a significant turnaround
at this segment.

Plant Services had a very positive product mix for the year. Although revenues
were down $2.3 million in fiscal 2002, gross margins improved from 10.2% to
12.0%. This improvement was the result of a better mix between turnaround and
maintenance work and excellent cost controls.

AST Services had mixed results for the year. New Tank Construction showed
significant growth in revenues and gross margins and our Western Division
continued to provide excellent results from tank repair and maintenance
activities as well as from small capital projects. The Gulf Coast region
continued to be very competitive with performance below anticipated results. Our
union operations had excellent growth in revenues but profitability was hurt by
the two large jobs that experienced gross margin losses in the third quarter of
this year.

We are not seeing as high a level of inquiries from the power sector as we saw
last year but we have been successful in capturing a number of smaller projects.
We do expect our power work to be down from last year's levels but we still
anticipate overall revenue growth in the AST Services segment of between 5% and
8%.

I would now like to turn the call over to Mike Hall, our CFO, who will discuss
in greater detail the financial results for the fourth quarter and full year.

                                       -5-



PART III - MIKE HALL'S COMMENTS

[MIKE START HERE]



Thanks, Brad.


I would like to discuss the specifics of the fourth quarter and full year
performance for each of the operating segments.

For the fourth quarter, as Brad noted, overall revenue growth was 11.8% with two
out of three operating segments reporting growth in gross revenues compared to
the fourth quarter of 2001. AST Services gross revenues gained 18.7% to $47.0
million from $39.6 million last year primarily due to increases in power work
and growth in new tank construction. Gross revenues for Construction Services
soared over 120% to $10.8 million from $4.9 million. However, Plant Services
lagged with gross revenues falling to $9.4 million from $14.6 million, as a
result of significantly lower turnaround work in the fourth quarter of this year
compared to the fourth quarter of last year. Our strongest quarter for
turnaround work in fiscal 2002 was in the third quarter.

For the quarter, gross margins improved in Construction Services to 11.1% from
2.0%, because of the success of the management team put in place 18 months ago
and the refocusing of the business on the capital work from Matrix's core
customers. AST Services' gross margins decreased from 13.6% to 11.9%, because of
the work performed in the fourth quarter to

                                      -6-



complete the two power projects that had third quarter losses and of the
extremely competitive market in the Gulf Coast. In Plant Services, gross margins
decreased to 11.7% from 15.1% as there was more turnaround work in last year's
fourth quarter and because of better fixed cost absorption last year with the
higher revenue levels.

For the full year, we were very pleased with the performance from our
Construction Services and Plant Services segments and were slightly disappointed
with the results from our AST Services segment. AST Services revenues grew
18.6%, or by $26.1 million to $166.8 million. Despite the excellent overall
growth in the business, the losses on the two large power jobs in the third
quarter narrowed gross margins in fiscal 2002 to 11.2% from 13.4% last year. As
a consequence, gross profit for AST Services for the year was $18.7 million,
similar to last year's results. Except for these two jobs, AST Services
continues to perform well with the business climate currently positive and
inquiry levels for new tank construction and repair and maintenance remaining
active.

For the full year, gross revenue growth for Construction Services was robust,
rising 45.7% to $26.8 million from $18.4 million in 2001. This achievement is a
direct result of the higher margin construction projects and cost controls put
in place last year. The higher margins, (10.8% this year versus 1.1% last year)
coupled with the higher sales volumes, produced a gross profit for 2002 of $2.9
million, which was $2.7 million more than the $0.2 million earned in 2001. Our
backlog in Construction Services stood at $29.3 million as of July 31, 2002.

                                      -7-



Gross revenues for Plant Services were affected by a change in the business mix
with a reduction in lower margin routine maintenance business and an improvement
in higher margin turnaround work. As a consequence profits rose even as revenue
fell. Gross revenues declined 6.9% to $30.9 million from last year's level of
$33.2 million. Gross margins for 2002 improved to 12.0%, which was better than
the 10.2% produced in 2001. These margin improvements produced a gross profit
gain of 8.8% for 2002 to $3.7 million from $3.4 million in 2001.

Consolidated SG&A expenses were $16.0 million for the full year of 2002 and
$14.1 million in fiscal 2001. On a year-over-year basis, SG&A expenses as a
percentage of revenue decreased to 7.2% compared to 7.4% for the same period
last fiscal year. The increases in SG&A expenses were primarily salary and
benefit related, most notably Health and Welfare costs.

Turning now to the balance sheet, working capital increased $2.0 million from
$23.8 million last year to $25.8 million at May 31, 2002 primarily due to higher
accounts receivable offset somewhat by higher billings in excess of costs and
higher accounts payable, all seasonal in nature.

Long-term debt including the current portion was $9.9 million at the end of
fiscal 2002, with the $6.4 million increase from year-end fiscal 2001 levels of
$3.5 million primarily due to the increase in working capital and capital
spending for the 12-month period which totaled $16.4 million.

                                      -8-



Capital expenditures during the twelve months ended May 31, 2002, totaled
approximately $16.4 million. Of this amount $6.9 has been used in the
construction of the offices and fabrication facility in Orange County,
California, and $3.8 million for the construction of the new facility at the
Tulsa Port of Catoosa to consolidate Tulsa operations. Other 2002 capital
expenditures included $1.4 million to purchase transportation equipment for
field operations, $3.2 million to purchase welding, construction and fabrication
equipment, and approximately $1.1 million for office equipment, furniture and
fixtures. $15.8 million has been budgeted for total capital expenditures for
fiscal 2003 of which $7.3 million is included for the Tulsa Port of Catoosa
construction. $2.5 million has been budgeted as a one-time expenditure to
support the expansion of Plant Services into the Midwest.

For the twelve months ended May 31, 2002, EBITDA was $14.7 million compared to
$11.8 million for the same twelve months last year with the 24.6% increase
primarily due to higher pre-tax earnings.

I will now turn the call back over to Brad, who will discuss the prospects for
the upcoming first quarter and for the full year.



PART IV - GUIDANCE

[BRAD STARTS HERE]



Thank you, Mike.

                                      -9-



We believe that Matrix is well positioned for continued growth. As a result, we
are reaffirming our earnings guidance for the year of between $.88 and $.93 per
fully diluted share. Our consolidated revenues are anticipated to grow between
6% and 10% with our gross margin improving to the 12.0% to 12.5% range. The
business climate remains positive and inquiry levels continue to be active.
Currently, our outlook for first quarter 2003 earnings is anticipated to be
between $.18 and $.21 per fully diluted share compared to $.15 per fully diluted
share in the first quarter of 2002.

And with that, we're ready to open it up for questions.
