As of September 25, 1999 and March 27, 1999, the Company had allowances for
obsolete raw materials of approximately $2,965,000 and $3,031,000, respectively.
Cost of sales for the three and six months ended September 25, 1999 and
September 26, 1998 include (recoveries) provisions to the allowance for obsolete
materials of $(65,789), $2,000 and $(65,789), $126,000, respectively.

NOTE 5     BORROWINGS

During the second quarter ended September 25, 1999, the Company and its existing
primary commercial bank signed a new $20 million credit facility. This facility
replaces the previous revolving line of credit and term loan facility. The new
asset based revolving credit facility bears interest at LIBOR plus 1.75% to
2.75% and/or prime to prime plus 0.75% depending upon certain financial ratios,
matures December 31, 1999 and is secured by certain assets of the Company. The
bank facility requires the payment of a monthly commitment fee equal to
three-eighths of one percent (3/8%) on the unused balance, and borrowings are
limited based upon certain collateral availability requirements and financial
ratios.

NOTE 6     EARNINGS PER COMMON SHARE

Basic earnings per share (EPS) is based on the weighted effect of all common
shares issued and outstanding, and is computed by dividing income available to
common shareholders by the weighted average number of common shares outstanding
during the period. Diluted EPS is similar to basic EPS except that the weighted
average of common shares outstanding is increased to include the number of
common share equivalents, when inclusion is dilutive. Common share equivalents
are comprised of stock options. The number of common share equivalents
outstanding relating to stock options is computed using the treasury stock
method. The following table sets forth the computation of basic and diluted
earnings per share (unaudited, in thousands, except per share amounts):

other statements made elsewhere in this report are made in reliance on the
Private Securities Litigation Reform Act of 1995. Actual results could differ
materially from those projected in the forward-looking statements throughout
this document as a result of the risk factors set forth below and elsewhere.

All percentage amounts and ratios were calculated using the underlying data in
thousands. Operating results for the three and six-month period ended September
25, 1999, are not necessarily indicative of the results that may be expected for

customers, availability of materials and components, the volume of orders
relative to the Company's capacity, timing of expenditures in anticipation of
future sales, the gain or loss of significant customers, variations in the mix
between consignment and component purchase arrangements with customers,
variations in the demand for products in the industries served by the Company
and general economic conditions. Operating results can also be significantly
influenced by the development and introduction of new products or technologies
by the Company's customers, or such customer's competitors, which may materially
and adversely affect the demand for the Company's services. The Company's
customers generally require short delivery cycles, and a substantial portion of
the Company's backlog is typically scheduled for delivery within 120 days. In
the absence of substantial backlog, quarterly sales and operating results depend
on the volume and timing of bookings received during the quarter which can be
difficult to forecast.


                                                                               8

<PAGE>   9

Backlog fluctuations affect the Company's ability to plan production and
inventory levels, which could lead to fluctuations in operating results.
Variations in the size and delivery schedules of purchase orders received by the
Company, changes in customers' delivery requirements, or the rescheduling or
cancellation of orders and commitments, may result in substantial fluctuations
in backlog from period to period. Accordingly, the Company believes that backlog
may not be a meaningful indicator of future operating results.

A significant portion of the Company's expenses is relatively fixed in nature
and planned expenditures are based in part on anticipated orders. The inability
to adjust expenditures quickly enough to compensate for a decline in net sales
may magnify the adverse impact of such decline in the Company's results of
operations. Due to the factors noted above and elsewhere in this Form 10-Q and
other filings by the Company with the Securities and Exchange Commission, the
Company's future earnings and stock price may be subject to significant
volatility, particularly on a quarterly basis. Past financial performance should
not be considered a reliable indicator of future performance and investors
should not use historical trends to anticipate results or trends in future
periods. Any shortfall in revenue and earnings from the levels anticipated by
securities analysts could have an immediate and significant effect on the
trading price of the Company's common stock in any given period. Also, the
Company participates in a highly dynamic industry, which often results in
volatility of the Company's common stock price.

CONCENTRATION OF CUSTOMERS. The Company's customer base is highly concentrated.
The Company's three largest customers accounted for approximately 13%, 11% and
11%, respectively, of net sales for the six months ended September 25, 1999. For
the six months ended September 26, 1998, the Company's three largest customers
accounted for approximately 46%, 8% and 5%, of its net sales. The Company
anticipates that a significant portion of its sales will continue to be
concentrated in a relatively small number of customers for the foreseeable
future. In addition, the Company's objective is to develop new and expand
existing relationships with leading and emerging OEM's in the electronics
industry. Such emerging growth and technology companies tend to have limited
operating histories, and also may have changes in management and limited
capitalization. As a result, the Company may experience difficulties in
maintaining long-term relationships with these customers and in receiving
payment for services rendered to them. To the extent that any significant
customers of the Company terminate their relationship with the Company, or the
Company is unable, for any reason, to receive payment for its services, the
Company's business, financial condition and results of operations likely would
be materially and adversely affected.

UNAVAILABILITY OF COMPONENTS AND MATERIALS. Components and material used by the
Company in producing surface mount assemblies and turnkey solutions are
purchased by the Company from approved suppliers of its customers. Any failure
on the part of these suppliers to deliver required components to the Company or
any failure of such components to meet performance requirements could impair the
Company's ability to meet scheduled shipment dates and could delay sales of
systems by the Company's customers and thereby adversely affect the Company's
business, financial condition and results of operations. The Company has in the
past experienced shortages of certain types of electronic components, and may
experience shortages of certain electronic components that are customer supplied
or are in short supply generally within the electronics industry. Component
shortages or price fluctuations, to the extent not absorbed by customers under
its agreements with the Company, could have a material adverse effect on the
Company's business, financial condition and results of operations. Certain
components used in a number of the Company's customer programs are obtained from
a single source.

VARIABILITY OF CUSTOMER REQUIREMENTS; ABSENCE OF LONG-TERM PURCHASE ORDERS. The
level and timing of purchase orders placed by the Company's customers are
affected by a number of factors, including variation in demand for the
customer's products, customer attempts to manage inventory and changes in the
customer's manufacturing strategies. Many of such factors are outside of the
control of the Company. The Company typically does not obtain long-term purchase
orders or commitments, but instead works with its customers to develop
nonbinding forecasts of the future volume of orders. Based on such nonbinding
forecasts, the Company makes commitments regarding the level of business that it
will seek and accept, the timing of production schedules and the levels and
utilization of personnel and other resources. Generally, customers may cancel,
reduce or delay purchase orders and commitments without penalty, except for
payment for services rendered, materials purchased or procured and, in certain
circumstances, charges associated with such cancellation, reduction or delay.
Significant or numerous cancellations, reductions or delays in orders by
customers, or inability by customers to pay for services provided by the Company
or to pay for components and materials purchased by the Company on such
customer's behalf, have adversely affected the Company's business, financial
condition and results of operations in the past and


                                                                               9

<PAGE>   10

could have a material adverse effect on the Company's business, financial
condition and results of operations in the future.

MANAGEMENT OF GROWTH AND EXPANSION. The Company's design, prototype, assembly
and turnkey solutions business and multi-site locations have grown rapidly in
recent years. This growth has increased the Company's fixed costs and required
it to hire additional personnel. Furthermore, the Company plans to establish
additional regional manufacturing services centers, which will increase the
Company's fixed costs, and will require additional personnel. A continuing
period of rapid growth, including geographic expansions and acquisitions, could
place a significant strain on the Company's management, operations and other
resources. The Company's ability to manage its growth will require it to manage
its existing resources more efficiently, to continue to invest in its
operations, including its financial and management information systems and
internal process controls, and to retain, motivate and manage its employees. If
the Company's management is unable to manage growth effectively, the quality of
the Company's services and its ability to retain key personnel could be
materially and adversely affected, which would have a material adverse effect on
the Company's business, financial condition and results of operations.

YEAR 2000 COMPLIANCE. The Company began a Year 2000 data assessment project in
fiscal 1998 to address all necessary code changes, testing and implementation
for all of its systems. Many of the Company's business and operating systems are
currently Year 2000 compliant, and therefore, the Company is undertaking
additional efforts to identify and modify those systems which may not be Year
2000 compliant. Anticipated spending for the Year 2000 date conversion project
will be expensed as incurred or new software will be capitalized and amortized
over the software's useful life and is not expected to have a significant impact
on the Company's results of operations. Project completion is planned during
calendar 1999 as described below. The costs of the project and the date on which
the Company believes it will complete the Year 2000 modifications are based on
management's best estimates, which are derived utilizing numerous assumptions of
future events, including the continuous availability of certain resources and
other factors. However, there can be no guarantee that these estimates will be
achieved and actual results could differ materially from those anticipated.
Specific factors that might cause such material differences include, but are not
limited to, the availability and cost of personnel trained in this area, the
ability to locate and correct all relevant computer codes, and similar
uncertainties. In addition, there can be no assurance that the systems of other
companies on which the Company's systems rely will be converted on a timely
basis or that such failure by another company to convert would not have an
adverse effect on the Company's systems.

NET SALES

Net sales for the second quarter ended September 25, 1999 was $23.2 million, 36%
below sales in the comparable prior year period of $36.2 million. Sales to new
customers partially offset certain discontinued customer programs representing
42% of sales last year, principally a large program brought in-house by a
customer.

Net sales for the six months ended September 25, 1999 was $55.1 million, 32%
below revenue of $80.5 million in the comparable prior year period. Revenues
from new customers partially offset discontinued programs representing 54% of
sales last year.

GROSS PROFIT

Gross profit is affected by, among other factors, the level of sales, product
mix, component costs and the level of capacity utilization at the Company's
facilities. Gross profit for the three months ended September 25, 1999 was $1.2
million versus $1.4 million for the three months ended September 26, 1998. The
Company's gross margin, gross profit as a percentage of net sales, increased to
5.4% in the second quarter of fiscal 2000, versus 3.8% in the second quarter of
fiscal 1999. This increase in margin reflected actions taken to reduce costs and
improve manufacturing efficiency, as well as a favorable product mix change.

Gross profit for the six months ended September 25, 1999 was $3.5 million versus
$4.5 million in the comparable year period, primarily as a result of lower sales
levels. Gross margin increased to 6.3% compared to 5.5% in the comparable year
period. The increase in gross margin primarily represented changes in product
mix towards lower material content, higher value added services and cost
reduction actions.

OPERATING EXPENSES

Selling, general and administrative ("SG&A") expenses consist primarily of
salaries and related expenses, marketing and promotional expenses, and sales
commissions paid to direct sales personnel and independent sales representative
organizations. SG&A expenses totaled $1.2 million in the second fiscal quarter
versus $1.6 million in the comparable prior year period. The decrease is
primarily attributed to $.2 million in certain recoveries and continued cost
management and controls. SG&A expenses represented 5.0% of net sales for the
three months ended September 25, 1999 compared to 4.3% for the three months
ended September 26, 1998 largely due to lower sales levels in the current
period.

SG&A expenses for the six months ended September 25, 1999 decreased to $2.8
million versus $3.3 million reported for the six months ended September 26, 1998
with the decline due to second quarter recoveries, cost control and lower
variable expenses. SG&A expenses represented 5.0% of net sales for the six
months ended September 25, 1999 compared to 4.1% of in the prior year largely as
a result of lower sales levels.

OTHER EXPENSE, NET

Other expense, net for the three months ended September 25, 1999 decreased to
$149,000 compared to $222,000 for the three months ended September 26, 1998. The
change in other expense, net was due to decreased interest expense incurred on
the Company's outstanding debt. Other expense, net for the six months ended
September 25, 1999 was $377,000 compared to $402,000 in the corresponding prior
year period. The change in other expense, net is primarily due to the decrease
in interest expense incurred on reduced borrowings coupled with a slight
decrease in interest income.

INCOME TAXES

The benefit for income taxes of $22,000 reflects an effective tax rate of 38%
for the three months ended September 25, 1999, the same effective tax rate for
the three month period ended September 26, 1998. The provision for income taxes
of $125,000 and $272,000 for the six months ended September 26, 1999 and
September 28, 1998, respectively, also reflect an effective tax rate of 38%.

LIQUIDITY AND CAPITAL RESOURCES

The Company generated $1.1 million and $1.5 million in cash flows from operating
activities for the three and six months ended September 25, 1999. Cash flows
from operating activities during the quarter resulted primarily from lower
receivable levels, which offset increased inventory and other changes in
operating working capital.

                                                                              11

<PAGE>   12

Working capital was $14.7 million and $15.7 million at September 25, 1999 and
March 27, 1999 respectively. In addition to the Company's working capital as of
September 25, 1999, which included cash and cash equivalents of $7.4 million,
the Company also had approximately $12.7 million in unused credit facilities.

Capital expenditures during the three and six months ended September 25, 1999
and September 26, 1998 were $148,000, $429,000, and $319,000, $974,000,
respectively. Management anticipates capital expenditures in fiscal 2000 will
approximate the level of capital expenditures made in fiscal 1999.

The Company's expenditures on research and development remained stable for the
three and six months ended September 25, 1999 and September 26, 1998 at $45,000
and $91,000, respectively.

The Company does not hold or issue derivative financial instruments in the
normal course of business.

During the second quarter ended September 25, 1999, the Company and its existing
primary commercial bank signed a new $20 million credit facility. This facility
replaces the previous revolving line of credit and term loan facility. The new
asset based revolving credit facility bears interest at LIBOR plus 1.75% to
2.75% and/or prime to prime plus 0.75% depending upon certain financial ratios,
matures December 31, 1999 and is secured by certain assets of the Company. The
bank facility requires the payment of a monthly commitment fee equal to
three-eighths of one percent (3/8%) on the unused balance, and borrowings are
limited based upon certain collateral availability requirements and financial
ratios. All debt is classified as current to reflect the new agreement.

During the quarter, the Company had $36 million in credit lines and equipment
financing facilities ($12.7 million unused), as follows: (i) a revolving line of
credit for $20 million from a commercial bank, and (ii) an equipment financing
facility for $16 million from a financial services company ($4 million unused at
September 25, 1999). There was $11.4 million and $10.1 million outstanding under
the commercial bank line of credit at September 25, 1999 and March 27, 1999,
respectively. In addition, there was $2.7 million outstanding under a term note
at March 27, 1999.

The bank revolving credit facility bore interest at LIBOR plus 1.25% to 1.75%
depending upon certain financial ratios and/or prime (such rate determined based
upon the amounts and period of loans), matured August 31, 1999 and was secured
by certain assets of the Company. The bank facility required the payment of a
monthly commitment fee equal to one-eighth of one percent (1/8%) on the unused
balance, and borrowings were limited based upon certain collateral availability
requirements. The term loan facility bore interest at 9.2% with a maturity of
August 31, 2000. The equipment financing facility provides for the leasing of
equipment over a five-year period commencing on the date of acceptance of such
equipment.

The financing facilities contain certain restrictions, which among others,
require maintenance of a minimum level of tangible net worth and other operating
and financial ratios. At March 27, 1999, the Company did not satisfy certain
financial covenants imposed under its financing facilities. The Company received
covenants and waivers with respect to these financial covenants as of March 27,
1999 and for the fourth quarter then ended.

Management believes that the Company has sufficient resources from cash provided
from operations and available borrowings to support its operations and capital
requirements through its fiscal year 2000. However, any material acquisitions of
complementary businesses, products or technologies could require additional
equity or debt financing. There can be no assurance that such financing will be
available on acceptable terms, if at all.

BACKLOG

The Company's backlog as of September 25, 1999 was approximately $85.8 million
compared to approximately $68.2 million as of June 26, 1999 and $101.6 million
as of March 27, 1999. Backlog consists of purchase orders received by the
Company and commitments under scheduled releases, both of which generally
specify delivery dates within twelve months. Variations in the size and delivery
schedules of purchase orders received by the Company, as well as changes in
customers' delivery requirements or the rescheduling or cancellation of orders
and commitments, has resulted in the past and may in the future result in
substantial fluctuation in backlog from period to period. Accordingly, the
Company believes that backlog may not be a meaningful indicator of future
financial


                                                                              12

results. For a discussion of these factors affecting the Company's business and
prospects, see "Item 1" "Business", "Risk Factors". Variability of Customer
Requirements and Fluctuations in Operating Results".

EMPLOYEES

As of September 25, 1999, the Company had approximately 460 full-time employees
supplemented from time to time by part-time employees. The employees are not
represented by a union and the Company believes its employee relations to be
satisfactory.

The Company's success depends to an extent upon the continued services of
several key employees. The loss of certain key personnel could have a material
adverse effect on the Company. The Company's business also depends upon its
ability to continue to attract and retain senior managers and skilled employees.
Failure to do so could adversely affect the Company's operations.

YEAR 2000 COMPLIANCE

Many currently installed systems and software products are coded to accept only
two digit entries in the date code field. These date code fields will need to
accept four digit entries to distinguish 21st century dates from 20th century
dates. As a result computer systems and/or software used by many companies will
need to be upgraded to comply with such "Year 2000" requirements.

An assessment of internal changes required for Year 2000 compliance has been
performed and the Company has determined that it will be necessary to upgrade
its network operating systems, test equipment, electronic mail systems, custom
reports and PC BIOS so that its computer systems will be Year 2000 compliant.
These modifications and replacements are being and will continue to be made in
conjunction with the Company's overall information systems initiatives. In
addition, the Company is continuing its discussions with third-party vendors to
ensure that any of their products that are incorporated into the Company's
products or currently in use by the Company can adequately deal with the change
in century. Areas being addressed include major third-party suppliers of
components of the Company's products as well as full reviews of the Company's
manufacturing equipment, telephone and voice mail systems, security systems and
other office support systems. The Company has also initiated formal
communications with significant suppliers and customers to determine the extent
to which the Company is vulnerable to those third parties' failure to remediate
their own Year 2000 issues. No significant information technology initiatives
have been deferred by the Company as a result of its Year 2000 project.

Since 1998, the Company has made Year 2000 compliance a priority in purchasing
and installation decisions. The Company's information systems department has
adopted a Year 2000 compliance program to assess and address any Year 2000
issues which remain related to the Company's information technology systems and
equipment. The following is a table showing the Company's status of the Year
2000 program based on management's assessment:

</TABLE>

As of September 25, 1999, the Company has spent approximately $75,000 of the
currently estimated $80,000 total cost of the program. Costs incurred and
expected to be incurred consist primarily of the cost of Company personnel
involved in updating applications and operating systems and the costs of
software updates and patches (many of which are provided free of charge from the
vendors). Such expenses are being funded through operating cash flows. The
Company has utilized the Company's internal technical personnel, and intends to
continue to use such personnel, to address Year 2000 issues, rather than
contract with third-party consultants.



                                                                              13
<PAGE>   14

Based on available information, the Company does not believe any material
exposure to a significant business interruption exists as a result of Year 2000
compliance issues, or that the cost of remedial actions will have a material
adverse effect on its business, financial condition or results of operations.
Accordingly, and as the program is on schedule to be completed by November 1999,
the Company has not formulated a "worst case" scenario or adopted any formal
contingency plan in the event its Year 2000 project is not completed in a timely
manner.

With respect to products manufactured by the Company based on third-party
designs, there can be no assurance that such products contain all necessary date
code changes necessary to ensure Year 2000 compliance. Although the Company has
not experienced any Year 2000-related product liability claims or lawsuits to
date, production of products that are not Year 2000 compliant may entail the
risk of such claims and lawsuits. The Company's defense against any future
lawsuits, regardless of their merit, could result in substantial expense to the
Company as well as the diversion of management time and attention. In addition,
Year 2000 product liability claims, regardless of the merit or eventual outcome
of such claims, could affect the Company's business reputation and its ability
to retain existing customers or attract new customers which, in turn, could have
a material adverse effect on the Company's business, financial condition and
results of operations.

The Company believes that the purchasing patterns of customers and potential
customers may be significantly affected by Year 2000 issues. Many companies are
expending significant resources to correct, patch or replace their current
software systems to achieve Year 2000 compliance. These expenditures may result
in reduced funds available to develop new products and purchase services such as
those offered by the Company.

Significant uncertainty still exists as to the global implications of the Year
2000 issue. Costs of defending and resolving Year 2000-related disputes,
reductions in product development programs by customers or the failure of the
Company to adequately resolve internal Year 2000 compliance issues could result
in a material adverse effect on the Company's business, operating results and
financial condition.
