COMPARISON OF THE THREE MONTHS ENDED MAY 31, 1999 TO THE THREE MONTHS ENDED MAY
31, 1998.

REVENUES - Revenues for the three months ended May 31, 1999 totaled $6.4 million
as compared to $6.9 million for the three months ended May 31, 1998, a decrease
of $0.5 million or 7.2%. This decrease was largely due to the decrease in shop
floor hours during the quarter ended May 31, 1999 as compared to the third
quarter of 1998. During the third quarter of 1999, the Company had 66,800
work-in-process shop floor hours as compared to 78,100 hours during the third
quarter of 1998, a decrease of 14.5%.






                                       8.

COST OF SALES - Cost of sales was $4.5 million for the three months ended May
31, 1999 as compared to $5.0 million for the three months ended May 31, 1998. As
a percent of revenue, cost of sales for the three months ended May 31, 1999 was
69.9% as compared to 73.2% for the three months ended May 31, 1998. The improved
gross margin was largely due to a decrease in the Company's direct costs expense
(a decrease of $670,000 or 10.4% of sales) and an increase in manufacturing
overhead expense (an increase of $147,000 or 2.3% of sales).

The decrease in direct costs expense was largely due to a decrease in direct
materials and outside services expense. The decrease from $1,830,000 or 26.6% of
sales for the three months ended May 31, 1998 to $1,533,000 or 23.8% of sales
for the three months ended May 31, 1999. This decrease was largely a result of
the Company upgrading its machining capability during fiscal 1998 for the
purpose of reducing the future expense of outsource machining. During fiscal
1998, the Company had reduced its existing machining capacity in that certain
machining centers were taken out-of-service during these upgrades. As a result,
it temporarily reduced the Company's machining capacity and the Company was
required to outsource more of its machining. Those machining centers taken
out-of-service during fiscal 1998, were in-service during the first nine months
of 1999 and reduced outsource machining expense from $336,000 for the three
months ended May 31, 1998 to $6,100 for the three months ended May 31, 1999.
Direct labor expense was $1,037,000 or 16.1% of sales for the three months ended
May 31, 1999 as compared to $1,411,000 or 20.5% of sales for the three months
ended May 31, 1998. Direct materials expense decreased from $1,226,000 or 17.8%
of sales for the three months ended May 31, 1998 to $1,025,000 or 15.9% of sales
for the three months ended May 31, 1999.

Manufacturing overhead expense increased from $1,366,000 or 19.9% of sales for
thee three months ended May 31, 1998 to $1,512,000 or 23.5% of sales for the
three months ended May 31, 1999. The largest increase in the third quarter of
1999 as compared to 1998 was the increase of $66,000 in depreciation expense.
This increase in depreciation expense was due to the Company's capital expansion
program, which resulted in a $1.5 million increase in depreciable property,
plant and equipment as of May 31, 1999 as compared to May 31, 1998. Other
manufacturing overhead expense increases include; a $33,000 increase in property
taxes (the Company's tax abatements on 1989 equipment acquisitions expired), a
$25,000 increase in building maintenance expense, and a $18,000 increase in
health insurance expense.


S,G & A EXPENSES - Selling, general and administrative expenses remained
consistent at approximately $550,000 for the three months ended May 31, 1999 and
May 31, 1998. General and administrative expense increases include; an increase
of $94,000 in supervision salaries and an increase of $6,000 in deferred
compensation/401(k) expense. Decreases in general and administrative expenses
include a decrease of $59,000 in the Michigan Single Business Tax, a decrease of
$33,000 in public company costs, a decrease of $10,000 in amortization expense,
a $9,000 decrease in legal expense and a $7,000 decrease in lease expense.
General and administrative expenses were 7.4% for the three months ended May 31,
1999 as compared to 6.9% for the three months ended May 31, 1998.

Selling expense increased from approximately $73,700 for the three months ended
May 31, 1998 to approximately $76,700 for the three months ended May 31, 1999.
This increase was largely due to an increase of $14,000 in travel expense and a
$9,000 decrease in commissions expense. Selling expenses were 1.2% for the three
months ended May 31, 1999 as compared to 1.1% for the three months ended May 31,
1998.


INTEREST EXPENSE - Interest expense for the three months ended May 31, 1999 was
approximately $35,000 as compared to approximately $182,000 for the three months
ended May 31, 1998. As a percentage of sales, interest expense



                                       9.

<PAGE>   10


decreased from 2.6% for the three months ended May 31, 1998 to 0.5% for the
three months ended May 31, 1999.

The decrease in interest expense was a result of the Company capitalizing
approximately $190,000 of interest on its construction in process during the
third quarter ended May 31, 1999. As of May 31, 1999, the Company had
approximately $10.4 million of construction in process. Lastly, debt levels as
of May 31, 1999 were higher than as of May 31, 1998 by $4.2 million. The
increase in debt was a result of higher accounts receivable balance and related
working capital line financing as well as term financing incurred to support the
Company's construction in process and capital expansion program.

MAY 31, 1998

million as compared to $18.4 million for the nine months ended May 31, 1998, a
decrease of $1.3 million or 7.1%. This decrease was largely due to the decrease
in shop floor hours during the nine months ended May 31, 1999 as compared to the
same period of 1998. During the nine months ended May 31, 1999, the Company had
188,500 work-in-process shop floor hours as compared to 199,600 hours during the
same period of 1998, a decrease of 5.5%.

COST OF SALES -- Cost of sales decreased from $13.7 million for the nine months
ended May 31, 1998 to $12.2 million for the nine months ended May 31, 1999. As a
percent of revenue, cost of sales for the nine months ended May 31, 1998 was
74.1% compared to 71.2% for the nine months ended May 31, 1999. The improved
gross margin was largely due to decreases in the Company's direct cost expense
of $1,967,000 and engineering expenses of $13,000, whereas manufacturing
overhead expenses increased by $491,000.

The decrease in direct cost expense was largely due to a decrease in direct
materials and outside services expense. Outside service expense decreased from
$1,649,000 for the nine months ended May 31, 1998 to $989,000 for the nine
months ended May 31, 1999. This decrease was largely a result of the Company
upgrading its machining capability during fiscal 1998 for the purpose of
reducing the future expense of outsource machining. During fiscal 1998, the
Company had reduced its' existing machining capacity in that certain machining
centers were taken out-of-service during these upgrades. As a result, it
temporarily reduced the Company's machining capacity and the Company was
required to outsource more of its machining. Those machining centers taken
out-of-service during fiscal 1998, were in-service during the first nine months
of 1999 and reduced outsource machining expense from $954,000 for the nine
months ended May 31, 1998 to $77,000 for the nine months ended May 31, 1999.
Direct labor expense was $3,851,000 or 20.9% of sales for the nine months ended
May 31, 1998 as compared to $2,935,000 or 17.2% of sales for the nine months
ended May 31, 1999. Direct materials expense decreased from $2,927,000 for the
nine months ended May 31, 1998 to $2,535,000 for the nine months ended May 31,
1999.

the nine months ended May 31, 1998 to $4,483,000 or 26.3% of sales for the nine
months ended May 31, 1999. The largest increase in the first nine months of 1999
as compared to 1998 was the increase of $261,000 in depreciation expense. This
increase in depreciation expense was due to the Company's capital expansion
program. Other manufacturing overhead expense increases include; a $33,000
increase in indirect labor, a $70,000 increase in manufacturing supplies, a
$66,000 increase in property tax expense, a $43,000 increase in health insurance
expense, a $20,000 increase in perishable tooling, and a $20,000 increase in
building maintenance. Decreases in manufacturing overhead expense for the nine

<PAGE>   12


receivable was due to the Company shipping and invoicing large contracts during
the last sixty days of the third quarter of 1999. The Company invoiced $6.6
million of invoicing during this period of which $5.1 million was paid in June,
1999. The increase in accounts payable was largely due to $1.6 million payable
for a new machining center which is currently in the process of being installed
as a part of the Company's capital expansion program. Upon final installation
the Company is financing such equipment through a five-year term loan with its
primary financial institution and the related term debt will classified as

quarter of 1999, the Company executed a $3.2 million non-revolving equipment
line of credit to finance the acquisition of two new machining centers. The
first machine was installed during the third quarter and $1.3 million was drawn
on such note with the remaining balance to be drawn upon final installation of
the second machining center. Upon final draw the note will amortized commencing
November 1, 1999 in monthly installments of $38,941 plus interest at the banks
prime rate less 25 basis points (currently 7.25%). The maturity date of this
note is November 1, 2004. During the nine months ended May 31, 1999 the Company
