5.   ACQUISITIONS

On September 1, 1999, Summa acquired substantially all of the assets of
Broadview Injection Molding Co., Inc. ("Broadview"). The aggregate purchase
price paid for Broadview consisted of $1,640,000 in cash, a note for $503,000,
subsequently paid, liabilities assumed or incurred of $364,000 and acquisition
costs of $26,000. The transaction has been accounted for using the purchase
method of accounting, and accordingly, the purchase price has been allocated to
identifiable tangible and intangible assets purchased and liabilities assumed or
incurred based upon their fair value at the date of acquisition. The excess of
the purchase price over the fair value of net acquired assets was $237,000 and
has been recorded as goodwill, which is being amortized on a straight-line basis
over 15 years.

On May 5, 2000, Summa acquired substantially all of the assets of
Yarbrough-Timco. The aggregate purchase price paid for Yarbrough-Timco consisted
of $150,000 in cash, a note payable to the seller in the amount of $50,000,
liabilities assumed or incurred of $124,000 and acquisition costs of $25,000.
The transaction has been accounted for using the purchase method of accounting,
and accordingly, the purchase price has been allocated to identifiable tangible
and intangible assets purchased and liabilities assumed or incurred based upon
their fair value at the date of acquisition. The excess of the purchase price
over the fair value of net acquired assets was $100,000 and has been recorded as
goodwill, which is being amortized on a straight-line basis over 15 years.


                                       7


On October 5, 2000, Summa acquired all of the outstanding capital stock of
Plastic Specialties, Inc. ("PSI"). The aggregate purchase price paid for PSI
consisted of $6,287,000 in cash, $4,873,000 in assumed debt concurrently paid,
preliminary liabilities assumed or incurred of $1,500,000 and acquisition costs
of $50,000. The transaction has been accounted for using the purchase method of
accounting, and accordingly, the purchase price has been allocated to
identifiable tangible and intangible assets purchased and liabilities assumed or
incurred based upon their fair value at the date of acquisition. The excess of
the purchase price over the fair value of net acquired assets was $1,940,000 and
has been recorded as goodwill, which is being amortized on a straight-line basis
over 35 years.

On December 1, 2000, Summa acquired substantially all of the assets of the Ram
Belts & Chains division ("Ram") of Rainbow Industrial Products Corp. The
aggregate purchase price paid for Ram consisted of $5,825,000 in cash, an
unsecured note for $750,000, liabilities assumed or incurred of $483,000 and
acquisition costs of $25,000. The transaction has been accounted for using the
purchase method of accounting, and accordingly, the purchase price has been
allocated to identifiable tangible and intangible assets purchased and
liabilities assumed or incurred based upon their fair value at the date of
acquisition. The excess of the purchase price over the fair value of net
acquired assets was $3,892,000 and has been recorded as goodwill, which is being
amortized on a straight-line basis over 25 years.

The Company utilized its remaining bank acquisition facility of $12,800,000 to
facilitate the PSI and Ram acquisitions.

The results of operations of each of the above described acquisitions have been
included in the consolidated results of operations and statements of cash flows
of the Company since the date of acquisition. The following pro forma financial
information presents the results of operations of the Company with PSI as though
the acquisition had been made as of September 1, 1999. Pro forma adjustments
have been made to give effect to the amortization of goodwill, adjustments in
depreciation and inventory value, interest expense related to acquisition debt
and the related tax effects. The following pro forma financial information does
not include adjustments to give effect to the Broadview, Yarbrough-Timco or Ram
acquisitions, as such adjustments would not be material.

6.       COMPREHENSIVE INCOME - DERIVATIVE FINANCIAL INSTRUMENTS

As part of its interest rate management program, the Company periodically enters
into interest rate swap agreements with respect to portions of its outstanding
debt. The purpose of these swaps is to mitigate the adverse effect of an
increase in interest rates. The interest rate swap agreements in place at
February 28, 2001 effectively convert $10,200,000 of the Company's variable rate
debt to a weighted average fixed rate of 9.2%. The swap agreements expire on
varying dates through September 2002. The unrealized gain or loss on interest
rate swaps is the Company's only other comprehensive income.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

Statements contained in this Quarterly Report on Form 10-Q, which are not purely
historical, are forward-looking statements within the meaning of Section 27A of
the Securities Act of 1933 and Section 21E of the Securities Exchange Act of
1934, including but not limited to statements regarding Summa's expectations,
hopes, beliefs, intentions or strategies regarding the future, such as those set
forth in Part II, Item 1 "Legal Proceedings" below. Actual results could differ
materially from those projected in any forward-looking statements as a result of
a number of factors, including those detailed in this "Management's Discussion
and Analysis" section and elsewhere herein and in the Company's Annual Report on
Form 10-K for the fiscal year ended August 31, 2000. The forward-looking
statements are made as of the date hereof, and the Company assumes no obligation
to update the forward-looking statements, or to update the reasons why actual
results could differ materially from those projected in the forward-looking
statements.

Summa manufactures diverse plastic products in two segments: Engineered Polymer
Components and Extruded Plastic Products. Summa designs and manufactures
injection-molded and thermo-formed plastic optical components for OEM customers
in the lighting industry; modular plastic conveyor belt and chain for the food
processing industry; engineered plastic fittings, valves, filters and tubing for
the agricultural irrigation industry; molded plastic coil forms ("bobbins") for
use in transformers, motors, relays and switches; extruded plastic sheet with
smooth or textured surfaces in various colors and sizes for diverse industrial
applications, and other molded and extruded plastic components for diverse
industries.

Growth has been achieved by acquisition, development of new products and
expansion of the Company's sales organization. There can be no assurance that
Summa will be able to continue to consummate acquisitions, develop new products
or expand sales to sustain rates of revenue growth and profitability in future
periods comparable to those experienced in the past several years. Any future
success that the Company may achieve will depend upon many factors including
factors which may be beyond the control of Summa or which cannot be predicted at
this time. See "Risk Factors" in the "Management's Discussion and Analysis of
Financial Condition and Results of Operations" section of the Company's Annual
Report on Form 10-K for the fiscal year ended August 31, 2000.

RESULTS OF OPERATIONS

The following table sets forth certain information, derived from Summa's
unaudited condensed consolidated statements of income, as a percent of sales for
the three and six month periods ended February 29, 2000 and February 28, 2001,
and the Company's effective income tax rate during those periods:

Sales for the second quarter, ended February 28, 2001, increased $1,418,000, or
5%, compared to the same period in the prior year, due to the inclusion of the
sales of newly acquired operations offset by decreased


                                       10


sales in previously owned operations. Due to the general business downturn, same
business sales in the second quarter were down 10% in the Engineered Polymer
Components segment, down 15% in the Extruded Plastic Products segment, and down
11% overall, compared to the second quarter of fiscal 2000. Of the 11% sales
decline, approximately 2% was a result of the discontinuation of, and price
increases on, some commodity products and manufacturing services, primarily in
the Extruded Plastic Products segment.

Sales for the six months ended February 28, 2001 increased $4,394,000, or 7%,
compared to the same period in the prior year, due to the inclusion of the sales
of newly acquired operations offset by decreased sales in previously owned
operations. Due to the general business downturn, same business sales in the
period were down 5% in the Engineered Polymer Components segment, down 7% in the
Extruded Plastic Products segment, and down 5% overall, compared to the first
six months of fiscal 2000. Of the 5% sales decline, approximately 1% was a
result of the discontinuation of, and price increases on, some commodity
products and manufacturing services, primarily in the Extruded Plastic Products
segment.

Gross profit for the second quarter decreased $627,000, or 7%, from the
comparable prior year period, primarily due to the effects of sales decreases in
previously owned operations and plant consolidation expenses of approximately
$500,000, partially offset by the effects of acquisitions. As a percent of
sales, gross profit decreased from 29.5% to 26.2% due to the effects of volume
decreases, plant consolidation expenses and inflation in costs not fully passed
through to customers by increased selling prices.

Gross profit for the six months ended February 28, 2001 decreased $329,000, or
2%, from the comparable prior year period, primarily due to the effects of sales
decreases in previously owned operations and plant consolidation expenses of
approximately $500,000, partially offset by the effects of acquisitions. As a
percent of sales, gross profit decreased from 29.2% to 26.7% due to the effects
of volume decreases, plant consolidation expenses and inflation in costs not
fully passed through to customers by increased selling prices.

Operating expenses for the second quarter ended February 28, 2001 increased
$729,000, or 13%, from the comparable prior year period, primarily due to the
inclusion of the operating expenses of recently acquired businesses partially
offset by decreases in operating expenses of previously owned operations. As a
percent of sales, operating expenses increased from 18.3% to 19.8%, primarily as
a result of the blending of newly acquired businesses with historically higher
operating expenses. Operating margin decreased from 11.2% in the second quarter
of fiscal 2000 to 6.4% in the second quarter of fiscal 2001 as a result of the
changes in gross margin and operating expenses discussed above.

Operating expenses for the six months ended February 28, 2001 increased
$1,488,000, or 14%, from the comparable prior year period, primarily due to the
inclusion of the operating expenses of recently acquired businesses partially
offset by decreases in operating expenses of previously owned operations. As a
percent of sales, operating expenses increased from 18.0% to 19.1%, primarily as
a result of the blending of newly acquired businesses with historically higher
operating expenses. Operating margin decreased from 11.2% in the first six
months of fiscal 2000 to 7.6% in the first six months of fiscal 2001 as a result
of the changes in gross margin and operating expenses discussed above.

Net interest expense for the quarter ended February 28, 2001 increased $310,000
from the comparable prior year period, primarily due to increased debt levels
related to acquisitions and higher average interest rates on recent acquisition
related term loans.

Net interest expense for the six months ended February 28, 2001 increased
$546,000 from the comparable prior year period, primarily due to increased debt
levels related to acquisitions and higher average interest rates on recent
acquisition related term loans.

The effective tax rate in the second quarter of fiscal 2001 decreased to 31.2%
from 37.2% in the comparable prior year period, due to a lower effective
combined state income tax rate and increased foreign sales


                                       11


corporation tax benefit.

The effective tax rate in the six months ended February 28, 2001 decreased to
34.0% from 37.1% in the comparable prior year period due to a lower effective
combined state income tax rate and increased foreign sales corporation tax
benefit.

The Company's backlog of unfilled orders, believed to be firm, increased from
$9,886,000 at August 31, 2000 to $11,051,000 at February 28, 2001 due to the
inclusion of backlog of recently acquired operations. Because the length of time
between entering an order and shipping the product is typically shorter than one
month, backlog levels are not a reliable indicator of future sales volume.

The following tables set forth the relative contribution of each of Summa's
reportable segments to the sales and operating income of the entire Company and
the operating margins of each segment:

The decrease in the operating profit of the Engineered Polymer Components
segment for the quarter and six month period is primarily due to the effects of
decreased sales in previously owned operations and plant consolidation expenses
incurred, partially offset by the contribution of newly acquired operations.

The decrease in the operating profit of the Extruded Plastic Products segment
for the quarter and six month period is primarily due to plant consolidation
expense incurred, decreased sales on previously owned operations, increased
resin costs and the effect of competitive conditions on gross margins, offset
partially by the inclusion of the results of newly acquired operations.

The increase in assets in the Engineered Components Segment is due primarily to
the inclusion of the assets of recently acquired operations. The increase in
assets in the Extruded Plastic Products segment is due to the inclusion of the
assets of recently acquired operations partially offset by a decrease in the
assets of the previously owned operations.

LIQUIDITY AND CAPITAL RESOURCES

WORKING CAPITAL. The Company's working capital at February 28, 2001 was
$16,864,000, compared to $12,761,000 at August 31, 2000. The increase was
primarily associated with the inclusion of the assets and liabilities of
recently acquired operations.

FINANCING ARRANGEMENTS. The Company has several debt relationships as described
below. Substantially all of the Company's assets are pledged to secure debt. The
Company is in compliance with financial and operating covenants required by the
term debt and bank line of credit.

Summary of the Company's debt at February 28, 2001:



                                                                    Weighted

Interest rates on most of the bank term loans are fixed for periods of one to
five years. Interest rates on the remainder of the bank term loans and the bank
line of credit are based on LIBOR, are subject to market fluctuation and are
subject to reduction as the Company achieves certain financial milestones.

Net cash provided by operating activities in the first six months of fiscal 2001
was $4,642,000, $1,530,000 more than in the first six months of fiscal 2000,
primarily due to changes in components of working capital partially offset by
lower net income.

Cash used in investing activities in the first six months of fiscal 2001 was
$16,360,000 versus $3,552,000 in the first six months of fiscal 2000, primarily
due to two acquisitions in 2001 (see Note 5), compared to a much smaller
acquisition made in 2000.

Cash provided by financing activities was $12,968,000 in the first six months of
fiscal 2001 versus $179,000 in fiscal 2000, primarily due to increased bank term
loans to facilitate acquisitions.

Summa believes that cash flows from operations and existing credit facilities
will be sufficient to fund working capital requirements, planned capital
expenditures and debt service for the next twelve months. The Company has a
strategy of growth by acquisition. In the event an acquisition plan is adopted
which requires funds exceeding the availability described above, an alternate
source of funds to accomplish the acquisition would have to be developed. The
Company has 10,000,000 shares of common stock authorized, of which 4,248,801
shares were outstanding at February 28, 2001 and 5,000,000 shares of "blank
check" preferred stock authorized, of which none is outstanding. The Company
could issue additional shares of common or preferred stock or enter into new or
revised borrowing arrangements to raise funds.


QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Except for the outstanding debt and related variable interest rates set forth in
"Managements' Discussion and Analysis of Financial Condition and Results of
Operations - Liquidity and Capital Resources" above, there are no material
changes to the disclosure set forth in Item 7A of the Company's Annual Report on
Form 10-K for the fiscal year ended August 31, 2000.

PART II - OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

The Company encounters lawsuits from time to time in the ordinary course of
business and, at February 28, 2001, the Company or its affiliates were parties
to several civil lawsuits. Any losses that the Company may suffer from current
or future lawsuits, and the effect such litigation may have upon the reputation
and marketability of the Company's products, could have a material adverse
impact on the results of future operations, the financial condition and
prospects of the Company.

ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS

On December 1, 2000, following the acquisition of Plastic Specialties, Inc.
("PSI"), the Company sold 5,861 restricted shares of the Company's common stock
to certain management employees of PSI, at the then current market price, for a
total consideration of $62,000, and granted non-qualified stock options to
certain PSI employees, at the then current market price. The options will vest
based on the percentage obtained by dividing the cumulative net income of PSI
after October 5, 2000 by $3.0 million, or fully in nine years. Proceeds were
used to reduce debt.

ITEM 3.  DEFAULTS UPON SENIOR SECURITIES

None.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

At the Company's Annual Meeting of Stockholders held on December 15, 2000,
incumbent directors Michael L. Horst and William R. Zimmerman were re-elected to
the Board of Directors of the Company to serve as one Class of the Board of
Directors for a three year term and until their successors are elected and
qualified. Messrs. Horst and Zimmerman each received approximately 3,705,000
votes in their favor, with no votes against re-election, approximately 53,000
abstentions and no broker non-votes.

ITEM 5.   OTHER INFORMATION

Prior to October 1986, a previously owned business unit of one of the Company's
subsidiaries operated a facility on property within an area subsequently
designated as a federal Superfund site. In 1997, the Company learned that
hazardous substances had been detected in the soil at the property and that the
current owner had been requested by a state agency to undertake additional
investigation at the property. The Company also became aware that the property
has been subject to a general notice letter issued by the United States
Environmental Protection Agency under the federal Superfund law. The Company, as
the successor to one of several prior tenants of the property, may be held
responsible for the contamination at the site regardless of whether its
subsidiary caused the contamination. The Company does not believe it is
responsible for any contamination at the property, and has not been notified or
contacted by any governmental authority in that regard, nor named in any
proceeding relating to the property. However, if the Company were held liable
under federal Superfund law, or other environmental law, or had to defend itself
against such a claim, the consequences could be material to the Company's
results of operations and financial position.
