ITEM 1.       BUSINESS.

GENERAL

Summa Industries ("Summa" or the "Company") was incorporated as Southern
California Plastics Co. in the State of California in 1942 and subsequently
reincorporated in the State of Delaware in 1998. Since 1946, Summa has been a
publicly-owned corporation whose Common Stock is registered under Section 12(g)
of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and is
currently traded on The Nasdaq National Market under the symbol "SUMX". Growth
has been achieved by acquisition, development of new products and expansion of
the Company's sales organization. Summa designs and manufactures
injection-molded and formed plastic optical components for original equipment
manufacturer ("OEM") customers in the lighting industry; molded plastic modular
conveyor belt and chain for the food processing industry; 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.

The principal executive offices of the Company are located at 21250 Hawthorne
Boulevard, Suite 500, Torrance, California 90503; its telephone number is (310)
792-7024; its facsimile number is (310) 792-7079; and its website is
www.summaindustries.com.

STRATEGY

Summa has a strategy of growth through acquisitions of profitable manufacturing
companies with proprietary products or protected market niches, with the intent
of expanding its operations by acquiring additional product offerings, enhancing
gross profit margins, increasing combined sales so that general and
administrative costs would constitute a smaller percentage of total revenues,
enhancing overall profitability, and increasing the market value of Summa's
Common Stock to provide liquidity and value for its stockholders by increasing
the number of outstanding shares in the public float and the trading activity in
the stock. In 1995, the Company refined the strategy to focus on manufacturers
of plastic components for industrial and commercial markets. In general, Summa's
corporate staff does not manage operations of acquired subsidiaries on an
ongoing basis, but provides planning, financial and legal oversight, and
financing; conducts the acquisition program and business development activities;
and manages the investor relations, risk management and employee benefit
programs. Corporate charges are assessed on a basis established annually,
related to asset utilization by each operating subsidiary.

HISTORY OF RECENT ACQUISITIONS -- CONTINUING OPERATIONS

KVP FALCON PLASTIC BELTING, INC. In July 1993, Summa acquired all of the
outstanding capital stock of KVP Systems, Inc., a California corporation,
renamed KVP Falcon Plastic Belting, Inc. in May 1998 after its acquisition of
Falcon Belting, Inc. described below ("KVP"), which designs, manufactures and
markets injection-molded plastic conveyor belting. Belts which can operate on a
curve were pioneered by KVP. In connection with this acquisition, which was
accomplished through the merger of KVP with and into a newly formed and
wholly-owned subsidiary of Summa, an aggregate of 555,275 shares of Summa's
Common Stock were issued to the shareholders of KVP in a transaction registered
under the Securities Act of 1933, as amended (the "Securities Act"). The
acquisition was accounted for using the purchase method of accounting and,
accordingly, the purchase price was 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 the net assets acquired amounted to $302,000 and was recorded as
goodwill which is being amortized on a straight-line basis over 25 years.

LEXALITE INTERNATIONAL CORPORATION. In November 1996, Summa acquired all of the
outstanding capital stock of LexaLite International Corporation, a Delaware
corporation ("LexaLite"), which manufactures injection-molded plastic prismatic
components for lighting fixtures, through the merger of a newly formed and
wholly-owned subsidiary of Summa with and into LexaLite. In connection with the
transaction, the former stockholders of LexaLite received shares of Summa's
Common Stock which in the aggregate constituted approximately 58% of the shares
of Summa's Common Stock outstanding immediately after the merger in a
transaction registered under the Securities Act. The acquisition was accounted
for using the purchase method of accounting and, accordingly, the purchase price
was allocated to identifiable tangible and intangible assets purchased and
liabilities assumed or incurred based upon their fair value at the date of
acquisition. During fiscal year 2000, a contingent liability in connection with
an Employee Stock Ownership Plan repurchase obligation was resolved which
resulted in a reduction of goodwill of $257,000. The excess of the purchase
price over the fair value of the net assets acquired amounted to $648,000 and
was recorded as goodwill which is being amortized on a straight-line basis over
25 years.

CALNETICS CORPORATION. In October 1997, Summa acquired all of the outstanding
capital stock of Calnetics Corporation, a California corporation ("Calnetics"),
through a merger of a newly formed and wholly-owned subsidiary of Summa with and
into Calnetics. As a result, Summa acquired the following operating subsidiaries
of Calnetics: Agricultural Products, Inc., a


                                       2

<PAGE>

California corporation ("API"), which manufactures plastic fittings, filters,
tubing and accessories, principally for agricultural irrigation; Ny-Glass
Plastics, Inc., a California corporation ("Ny-Glass"), which manufactures
plastic parts, principally by use of injection molding and structural foam
molding techniques, and performs certain value-added services for customers
in a variety of industries; and Manchester Plastics Co., Inc., a California
corporation ("Manchester Plastics"), which manufactures proprietary and
custom acrylic, polycarbonate and polystyrene plastic sheet products,
principally for the building materials and industrial plastics industries.
The total acquisition cost was $31,792,000, consisting of cash due to former
Calnetics shareholders of $22,335,000, acquisition costs of $50,000,
liabilities assumed or incurred of $8,062,000 and an estimated fair value of
$1,345,000 for options issued in conjunction with the transaction, primarily
replacement options issued to Calnetics employees who continued with the
Company. The acquisition was accounted for using the purchase method of
accounting and, accordingly, the purchase price was allocated to identifiable
tangible and intangible assets purchased and liabilities assumed or incurred
based upon their fair value at the date of acquisition. During fiscal year
2000, an insurance claim settlement was received which resulted in a
reduction of the acquisition cost and of goodwill in the amount of $350,000.
The excess of the purchase price over the fair value of the net assets
acquired amounted to $13,624,000 and was recorded as goodwill which is being
amortized on a straight-line basis over 40 years.

FALCON BELTING, INC. In May 1998, Summa acquired all of the outstanding capital
stock of Falcon Belting, Inc., an Oklahoma corporation ("Falcon"), which
manufactures modular plastic conveyor belting used in food processing
industries. The operations of Falcon were promptly consolidated with KVP. The
total acquisition cost was $5,125,000, consisting of $2,636,000 in cash and the
present value of obligations to make future payments to the former owner of
Falcon and liabilities assumed or incurred of $2,489,000. The acquisition was
accounted for using the purchase method of accounting and, accordingly, the
purchase price was allocated to identifiable tangible and intangible assets
purchased and liabilities assumed or incurred based upon their fair value at the
date of acquisition. During fiscal year 1999, a contingency was resolved which
resulted as a reduction of the total acquisition cost and of goodwill in the
amount of $125,000. The excess of the purchase price over the fair value of the
net assets acquired amounted to $1,870,000 and was recorded as goodwill which is
being amortized on a straight-line basis over 30 years.

CANYON MOLD. In September 1998, Summa acquired substantially all of the assets
of Canyon Mold, Inc., a California corporation. The operations of Canyon Mold
were promptly relocated to and integrated into the Company's molding facility in
Corona, California. Canyon Mold had provided tool design and manufacturing
services almost exclusively for the Company. The total acquisition cost was
approximately $200,000 in cash and assumed liabilities. No goodwill was recorded
in this transaction.

PLASTRON INDUSTRIES, INC. In March 1999, Summa acquired substantially all of the
assets of Plastron Industries, L.P. ("Plastron") which manufactures molded
plastic coil forms ("bobbins") for use in transformers, motors, relays and
switches. The aggregate purchase price paid for Plastron consisted of
$19,525,000 in cash; a four-year warrant exercisable to purchase up to 200,000
shares of the Company's common stock at $11.75 per share valued at $278,000;
investment banking fees consisting of a $125,000 cash payment and stock options,
valued at $32,000; and the assumption of certain liabilities, principally trade
payables and accrued obligations of $2,220,000. 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 fair value of the net
assets acquired amounted to $13,781,000 and has been recorded as goodwill which
is being amortized on a straight-line basis over 35 years. In April 2000, Summa
repurchased the warrant for $500,000.

BROADVIEW INJECTION MOLDING, INC. In September 1999, Summa acquired
substantially all of the assets of Broadview Injection Molding Co., Inc.
("Broadview"), which manufacturers molded plastic coil forms ("bobbins") for use
in transformers, motors, relays and switches. The aggregate purchase price paid
for Broadview consisted of $2,143,000 in cash, 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 the net
assets acquired amounted to $237,000 and has been recorded as goodwill, which is
being amortized on a straight-line basis over 15 years.

YARBROUGH-TIMCO. In May 2000, Summa acquired substantially all of the assets of
Yarbrough-Timco ("Yarbrough"), which is a distributor and manufacturer of molded
plastic coil forms ("bobbins") for use in transformers, motors, relays and
switches. The total acquisition cost was $349,000, consisting 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 the
net assets acquired amounted to $100,000 and has been recorded as goodwill which
is being amortized on a straight-line basis over 15 years.

RECENT EVENTS


                                       3

<PAGE>

PLASTIC SPECIALTIES, INC. In October 2000, Summa acquired all of the outstanding
capital stock of Plastic Specialties, Inc., a California corporation ("PSI"),
which is a manufacturer of thermoformed, extruded and injection-molded plastic
prismatic components for lighting fixtures. The acquisition cost consisted of
$6,287,000 in cash, $4,873,000 in assumed indebtedness, subsequently paid, and
liabilities assumed or incurred to be determined. The Company used its existing
acquisition facility to finance the transaction.

In evaluating future acquisitions, Summa will endeavor to identify target
companies that manufacture plastic components which have a proprietary advantage
because of patent protection, brand recognition, unique manufacturing processes
or other comparable characteristics. It is anticipated that target companies
typically will have been profitable in recent periods, particularly if the
acquisition is to be made through the issuance of Summa Common Stock, so that
the acquisition will not have an immediate dilutive effect on post-acquisition,
consolidated earnings per share. Since it is usually intended that each acquired
company will be maintained as a separate operating unit, existing management of
each target company will be extensively evaluated in an attempt to ascertain
whether such management possesses the capability and compatibility to continue
to manage the operations following the acquisition. Perhaps most importantly,
Summa will seek to determine that there is a significant likelihood that a
sustainable increase in earnings per share within twelve months of the closing
can reasonably be expected. For a history of recent divestitures, see Note 16 in
the "Notes to Consolidated Financial Statements" of the Company in this Annual
Report on Form 10-K.

Although the existing management of an acquired company typically would be
retained to manage day to day operations, it is anticipated that the business of
the acquired company could be expanded through the support of Summa's corporate
staff. Any such expansion could place a significant strain on Summa's management
and resources, require Summa to implement additional operating, marketing and
financial controls, and necessitate that Summa hire additional personnel, which
could have a significant adverse effect on Summa's operating results. It is also
likely that any such acquisition would require Summa to raise additional capital
to finance the acquisition or provide working capital to the acquired company.
If this additional capital were raised through debt financings, Summa would
incur substantial additional interest expense; sales of additional equity to
raise the needed capital would dilute, on a pro-rata basis, the percentage
ownership of all holders of Summa Common Stock. There can, however, be no
assurance that sufficient financing will be available to Summa to continue its
acquisition strategy on terms and conditions that are acceptable to Summa.

Continued implementation of the Company's strategy will depend to a significant
extent upon the ability of Summa's top management in identifying appropriate
candidates for acquisition, negotiating deals acceptable to the Board of
Directors and stockholders of the Company, including obtaining acceptable
acquisition prices in the current environment of dramatically higher asking
prices, and supervising the management of operating subsidiaries. Furthermore,
with a focus on businesses which manufacture plastic components, the number of
opportunities which meet this acquisition criteria is smaller. In addition, with
the increased size of the Company, larger acquisition candidates would have to
be sought in the future to sustain the growth rate of Summa, and the number of
such candidates is smaller. Competition for such acquisitions may be greater and
there is no assurance Summa will be able to successfully compete with larger
companies and buyer groups to consummate additional acquisitions. There can be
no assurance that the terms upon which a prospective company can be acquired
will be favorable to Summa, or that Summa will not encounter unforeseen
difficulties and liabilities in connection with any such acquisition.

SEGMENTS; PRODUCTS

Summa manufactures diverse plastic products in two segments:

ENGINEERED POLYMER COMPONENTS

OPTICAL COMPONENTS. Summa's optical components include prismatic lenses,
refractors and reflectors molded and formed from clear plastic, which are used
in commercial and industrial lighting fixtures and in similar applications such
as lighted navigational aids, traffic signals and vehicles. Most of the products
are injection-molded from specially compounded lighting grade polycarbonate or
acrylic. The principal advantages of Summa's injection-molded plastic components
over more traditional glass or metal components are superior optical
performance, lighter weight, and in certain instances, lower cost.

IRRIGATION COMPONENTS. Summa's irrigation components include injection-molded
fittings, valves, filters and accessories for drip irrigation systems. The use
of drip irrigation systems conserves water and allows more precise control of
delivery of water and soluble nutrients to plants than is possible with spray,
sprinkler or flood irrigation techniques.

CONVEYOR COMPONENTS. Summa's conveyor components include engineered plastic
components which form conveyer belts and chains. The components in Summa's
product line, many of which are patented, are constructed of non-toxic,
non-corrosive plastic materials and are designed to be easily cleaned,
meeting FDA-USDA requirements and specifications. The components do not
require lubrication and thus offer the advantage of operation free from
contaminants such as grease, oil and metal particles. Because these
components are lightweight, they require less energy to operate than steel
belts, and are quieter in operation and easier to service in place than metal
belts.

WINDING CORES. Summa's winding cores are thermoplastic and thermoset coil forms
or "bobbins" used in the manufacture of


                                       4

<PAGE>

magnetic devices including transformers, relays, switches, power supplies and
small electro motors. These devices are utilized in controls, appliances,
vehicles, telecommunications equipment and many other applications.

In addition, the Company molds components for electronic products and
manufactures miscellaneous parts for diverse industrial and commercial markets.

EXTRUDED PLASTIC PRODUCTS

SHEET. Summa extrudes plastic sheet with smooth or textured surfaces in various
colors and sizes for diverse industrial applications.

TUBING. Summa extrudes plastic tubing for use in irrigation and industrial
applications.

For financial information by segment, see Note 14 in the "Notes to Consolidated
Financial Statements" of the Company in this Annual Report on Form 10-K.

RESEARCH AND DEVELOPMENT

Summa invests significantly in the development of new products and manufacturing
processes. Only direct costs associated with tooling for new products are
capitalized. All other costs, including salaries and wages of employees involved
in research and development, are expensed as incurred.

PRODUCTION

INJECTION MOLDING. Summa's principal manufacturing operation is injection
molding of plastic parts. Some products are molded by third-party vendors.
Injection molds and tools are made by Summa and outside vendors. Products are
made on modern molding machines, which range from 28 to 1500 tons clamping
force, using a wide variety of plastic resins. Ancillary equipment and special
operations include automatic resin feed systems, insert molding, robotics,
painting, vacuum deposition coating with reflective metallic films, assembly,
packaging and warehousing.

THERMOFORMING. Summa vacuum forms and pressure forms products from sheet which
it produces. Tooling for the forming process is produced by third-party vendors.

EXTRUSION. Summa extrudes plastic sheet and tubing products. The Company's sheet
products are made of polycarbonate, acrylic and polystyrene, while the tubing is
extruded from polyethylene and polyvinylchloride (PVC).

In addition to injection molding, thermoforming and extrusion, Summa performs
additional production operations including machining and welding of plastic
parts, coating, assembly and testing. Summa operates on a just-in-time basis
with many of its customers, and inventories are managed to minimal levels. Three
of Summa's manufacturing plants are ISO 9002 registered.

MARKETING AND DISTRIBUTION

Summa manufactures plastic products and components which are generally sold to
other manufacturers who incorporate Summa's materials and components in their
products, and to businesses which incorporate the Company's products in systems
assembled for their own use or for their customers' use. The Company generally
considers its customers to be OEM's, "end users" and distributors. Most sales
are made directly by employees of the Company, although Summa utilizes several
independent manufacturers' representatives and certain sales are made through
distribution channels. In recent years, the Company has expanded the size of its
direct sales staff substantially and has also increased its export sales. The
Company distributes its products principally by truck through the use of
independent freight entities and, to a lesser extent, by air and sea transport.

Summa's largest three customers accounted for 8.6%, 5.0% and 4.4% of sales in
fiscal 2000. The Company has thousands of active accounts including many Fortune
1,000 and large privately held businesses.

RAW MATERIALS

Summa's principal raw material is pelletized plastic resin which is delivered in
bulk by truck or in large boxes, typically weighing 1,000 pounds ("Gaylords").
The Company is a large user of resin and does not rely on any single vendor for
more than 15% of its raw material. Every material used is available from several
vendors. Primary resins used include polycarbonate, acrylic, polystyrene,
polyethelyne, polyvinylchloride, polypropylene, acetal and nylon. Principal
vendors include AtoFina, Bayer, Cyro, Dow, Dupont, GE Plastics and Ineos among
others. The resins used by the Company are


                                       5

<PAGE>

crude oil or natural gas derivatives and may be affected to some extent by
the supply, demand and price trends in the petroleum industry. Despite
supplier plant disruptions at several facilities due to fire and other
causes, the Company did not incur any material shortages or unavailability
during fiscal 2000. Although prices were relatively stable during fiscal
1998, during fiscal 1999 and fiscal 2000 there have been several increases in
prices for certain types of resin.

BACKLOG AND SEASONALITY

On August 31, 2000, Summa's continuing businesses had a backlog of orders,
believed to be firm, in the amount of $9,886,000, as compared to a backlog of
$9,338,000 from continuing businesses as of August 31, 1999. The open order
backlog is comprised of orders for components, spare parts and tooling, with
scheduled deliveries from September 2000 through fiscal 2002. Because the length
of time between entering an order, shipping the product and recording a sale are
typically shorter than 90 days, backlog levels are not a reliable indicator of
future sales volume.

Summa's sales exhibit modest seasonality, principally for its irrigation
components. Excluding the effects of growth and acquisitions, the Company would
expect sales, as a percentage of fiscal year's sales, to occur approximately as
follows:

<TABLE>

     3rd quarter............................................         26%
     4th quarter............................................         26%
                                                                    ----
                                                                    100%
                                                                    ----

</TABLE>

Because a portion of overhead is fixed and, therefore, does not vary with sales
volume, profit may vary from quarter to quarter with more volatility than sales
volume.

COMPETITIVE CONDITIONS

The markets for the products currently manufactured and sold by Summa are
characterized by extensive competition. There are a number of companies that
currently offer competing products nationally and internationally, and in
certain geographic areas the Company has competition from local manufacturers as
well. It can be expected that additional competing products will be introduced
by other companies in the future. Many existing and potential competitors have
greater financial, marketing and research capabilities than Summa. Some of
Summa's largest customers have the resources to internally manufacture products
comparable to those currently purchased from Summa, and some of Summa's
customers also compete with the Company in certain areas.

Summa believes that its trade names and reputation are significant to its
competitive position. In addition, Summa believes that price is a significant
element of competition. However, factors such as engineering, performance,
availability and reliability are considered in the purchasing process. The
performance of Summa in the future will depend on the ability of its operating
subsidiaries to develop and market new products that will gain customer
acceptance and loyalty, as well as its ability to adapt its product offerings to
meet changing pricing considerations and other market factors. The Company's
operating performance would be adversely affected if its operating subsidiaries
were to incur delays in developing new products or if such products did not gain
market acceptance. There can be no assurance that existing or future products
will be sufficiently successful to enable Summa's operating subsidiaries to
effectively compete in their respective markets or, should new product offerings
meet with significant customer acceptance, that one or more current or future
competitors will not introduce products that render the Company's products
noncompetitive.


                                       6

<PAGE>

PATENTS, TRADEMARKS AND LICENSES

The Company owns and licenses many domestic and foreign patents on products
which it has developed or acquired that expire on dates ranging to 2017. In
addition, several patent applications are currently in process. The extent to
which patents provide a commercial advantage or inhibit the development of
competing products varies. The Company does not capitalize expenses related to
product development and patent applications. Summa also relies upon common law
concepts of confidentiality and trade secrets, as well as economic barriers
created by the required investments in tooling and technical personnel and the
development of customer relationships, to protect its proprietary products.
Summa also has domestic and foreign trade name and trademark registrations
covering many of the names and logos which appear on its products which are
helpful in enabling the Company to maintain its present competitive position.

ENVIRONMENTAL MATTERS

The Company is subject to various environmental laws and regulations governing
air quality, water quality and hazardous waste management and disposal,
including such laws and regulations of the federal government and the states of
California, Michigan, Oklahoma, Illinois, Florida, Mississippi and Tennessee.
The Company does not anticipate that future expenditures for the compliance with
such laws and regulations will have a material effect on its capital
expenditures or except as set forth below, financial condition or, its results
of operations.

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.

EMPLOYEES

At October 18, 2000, Summa had 927 employees, including five employees who
comprise the Company's corporate staff. None of Summa's employees is covered by
a collective bargaining agreement. The Company considers its relationship with
its employees to be good.

EXPORT SALES

For information regarding Summa's export sales by geographic area for the past
three fiscal years, see Note 13 in the "Notes to Consolidated Financial
Statements" of the Company in this Annual Report on Form 10-K.

In addition, the Company owns 63,000 square feet of factory and office space in
Fullerton, California, and 15,000 square feet of office and warehouse space in
Charlevoix, Michigan, which are leased to unrelated parties. The Fullerton lease
expires in July 2006 and the Charlevoix leases expire in November 2001.

ITEM 3.       LEGAL PROCEEDINGS.

The Company encounters lawsuits from time to time in the ordinary course of
business and, at August 31, 2000, the Company and/or its affiliates were parties
to several civil lawsuits. Summa does not expect that the resolution of these
lawsuits will have a material adverse impact on future results of operations or
financial position. Certain lawsuits filed against the Company in the past have
contained claims not covered by insurance, or sought damages in excess of policy
limits, and such claims could be filed in the future. Any losses that Summa may
suffer from such lawsuits, and the effect such litigation may have upon the
reputation and marketability of Summa's products, could have a material adverse
impact on the future results of operations, financial condition and/or prospects
of the Company. See also "Business--Environmental Matters" above.

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

No matters were submitted during the fourth quarter of the fiscal year ended
August 31, 2000 to a vote of Summa's stockholders, through solicitation of
proxies or otherwise.

RECENT MARKET PRICES

Summa's Common Stock is traded on The Nasdaq National Market under the symbol
"SUMX." During the year ended August 31, 2000, the average weekly trading volume
was approximately 67,000 shares. The stock markets have experienced extreme
price and volume fluctuations during certain periods. These broad market
fluctuations and other factors may adversely affect the market price of Summa's
Common Stock for reasons unrelated to Summa's operating performance. The
following table sets forth the high and low prices for a share of Summa's Common
Stock on The Nasdaq National Market for the periods indicated.

</TABLE>

On October 18, 2000, the closing price on The Nasdaq National Market for a share
of Summa Common Stock was $11.00.

DESCRIPTION OF SECURITIES

The authorized capital stock of Summa consists of 10,000,000 shares of Common
Stock, $.001 par value, and 5,000,000 shares of Preferred Stock, $.001 par
value. As of August 31, 2000, 4,224,715 shares of the Company's Common Stock
were issued and outstanding and no shares of Preferred Stock had been issued or
were outstanding. The number of holders of record of Summa's Common Stock as of
August 31, 2000 was 328. In addition, Summa estimates that there are 2,500
additional stockholders whose shares are held in "street name", including
approximately 700 stockholders who own shares through the Employee Stock
Ownership Plan.

COMMON STOCK. Holders of Common Stock are entitled to one vote per share on each
matter submitted to a vote of the stockholders of Summa, and there is no
cumulative voting for the election of directors. Subject to preferences that may
be applicable to the holders of any outstanding Preferred Stock, each holder of
Common Stock is entitled to receive ratably such dividends, if any, as may be
declared by the Board of Directors out of funds legally available therefor. Upon
the liquidation, dissolution or winding up of Summa, holders of Common Stock are
entitled to share ratably in all assets of Summa which are legally available for
distribution, after payment of all debts and other liabilities and the
liquidation preference of any outstanding Preferred Stock. Holders of Common
Stock have no preemptive, subscription, redemption or conversion rights. The
transfer agent and registrar for the Common Stock is U. S. Stock Transfer
Corporation, 1745 Gardena Avenue, Glendale, California 91204, www.usst.com, and
its telephone number is: (800) 835-8778.

PREFERRED STOCK. The Board of Directors is authorized, subject to any
limitations prescribed by the laws of the State of Delaware, but without further
action by Summa's stockholders, to provide for the issuance of Preferred Stock
in one or more series, to establish from time to time the number of shares to be
included in each such series, to fix the designations, powers, preferences and
rights of the shares of each such series and any qualifications, limitations or
restrictions thereof, and to increase or decrease the number of shares of any
such series (but not below the number of shares of such series then outstanding)
without any further vote or action by the stockholders. Although Summa has no
present plans to issue any additional shares of Preferred Stock, the issuance of
Preferred Stock in the future could provide voting or conversion rights that
would adversely affect the voting power or other rights of the holders of Common
Stock and thereby reduce the value of the Common Stock. In addition, the
issuance of Preferred Stock may have the effect of delaying, deferring or
preventing a change in control of Summa. In particular, specific rights granted
to future holders of Preferred Stock could be used to restrict Summa's ability
to merge with or sell its assets to a third party, or otherwise delay,
discourage or prevent a change in control of Summa.

ANTI-TAKEOVER DEVICES. In addition to the ability to issue Preferred Stock,
Summa's Certificate of Incorporation and Bylaws specifically prohibit cumulative
voting and the right of stockholders to call a special stockholders meeting,
provide for the classification of the Board of Directors into three classes with
one class elected annually, require a two-thirds supermajority stockholder vote
to amend certain provisions of the Certificate of Incorporation and Bylaws, and
include other provisions which are also likely to delay, discourage or prevent a
change in control of Summa not approved by the Board of Directors and the
Company's stockholders. Further, neither the Company's Certificate of
Incorporation and Bylaws nor Delaware law prohibit the Company from adopting a
stockholders' rights plan, or poison pill.

SHARES ISSUABLE UPON EXERCISE OF OPTIONS

As of August 31, 2000, 1,270,485 shares of Summa common stock are issuable upon
exercise of options granted and/or available to be granted under its stock
option plans and in connection with acquisitions, most of which are registered
under the Securities Act. The existence of these stock options may adversely
affect the terms on which Summa can obtain additional financing, and the holders
of the options can be expected to exercise or convert them at a time when Summa,
in all likelihood, would be able to obtain additional capital by offering shares
of its Common Stock on terms more favorable to Summa than those provided by the
exercise or conversion of such options. All options vest in full immediately
prior to a change of control of the Company, as defined in the stock option
plans.

DIVIDEND POLICY

Summa has not paid a cash dividend since the fiscal year ended August 31, 1983.
Summa does not currently intend to pay cash dividends on its Common Stock in the
foreseeable future.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS.

GENERAL

Statements contained in this Annual Report on Form 10-K, 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 "Business--Legal Proceedings" above. 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 the "Risk Factors" section of
this "Management's Discussion and Analysis" section and elsewhere in this Annual
Report on Form 10-K. 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. See "Business -- Segments; Products"
above. Summa designs and manufactures injection-molded and 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. See "Business -- Segments;
Products" above, "Results of Continuing Operations -- Segment Information"
below, and Note 14 in the "Notes to Consolidated Financial Statements" of the
Company in this Annual Report on Form 10-K.

RISK FACTORS

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. See "Business
-- History of Recent Acquisitions -- Continuing Operations" and "-- Recent
Developments" above. 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. Uncertainties and factors which could
cause actual results or events to differ materially from those set forth or
implied include:

-   changes in the markets for the products offered by the Company through its
    operating subsidiaries
-   increased levels of competition, including the entry of additional foreign
    and domestic competitors and increased success by existing competitors
-   reduced margins caused by competitive pressures and other factors
-   increases in operating costs including costs of production, energy,
    materials, supplies, personnel, equipment, import duties and transportation
-   increases in borrowing costs and the availability of funds
-   increases in governmental regulation imposed under federal, state or local
    laws, including regulations applicable to environmental, labor and trade
    matters
-   changes in governmental regulation, including changes affecting the
    favorable tax benefits for export sales made by domestic entities through
    foreign sales corporations (Summa obtained a $230,000 tax benefit in fiscal
    2000)
-   changing customer profiles and general economic and industry conditions
    that affect customer demand and sales volume, both domestically and
    internationally
-   the introduction of new products by Summa or its competitors
-   the need to make material capital expenditures
-   the timing of the Summa's advertising and promotional campaigns

</TABLE>

NET SALES. For the year ended August 31, 1999, net sales from continuing
operations increased by $21,019,000, or 25%, over the prior fiscal year, due
primarily to the inclusion of sales of newly acquired operations. See "Business
-- History of Recent Acquisitions -- Continuing Operations" above. Comparative
trailing twelve months' sales from continuing businesses grew at 5% in the
Engineered Polymer Components segment, declined 5% in the Extruded Plastic
Products segment, and grew at 3% on a consolidated basis in fiscal 1999. The
decline in sales in the Extruded Plastic Products segment is not apparent from
footnote 14 in the "Notes to Consolidated Financial Statements", as the
extrusion operations were acquired during fiscal 1998 and results were included
for ten months thereof. The decline was attributable to management turnover at a
sheet extrusion plant and preparations for the relocation of that plant, which
was completed in the first quarter of fiscal 2000.

For the year ended August 31, 2000, net sales increased $16,849,000, or 16%,
over the prior fiscal year, due primarily to the inclusion of sales of newly
acquired operations. See "Business -- History of Recent Acquisitions --
Continuing Operations" above. Comparative same business unit sales grew 8% in
the Engineered Polymer Components segment due to expanded sales programs, new
product introductions and market growth, declined 4% in the Extruded Plastic
Products segment due to industry consolidation and competitive conditions, and
grew 6% on a consolidated basis in fiscal 2000.

COST OF SALES. For the year ended August 31, 1999, cost of sales from continuing
operations increased by $14,750,000, or 25%, over the prior fiscal year, due
primarily to the inclusion of expenses of newly acquired operations, and
increased sales volume and related expenses. See "Business -- History of Recent
Acquisitions -- Continuing Operations" above.

For the year ended August 31, 2000, the cost of sales increased by $14,349,000,
or 19%, over the prior fiscal year, due primarily to the inclusion of the costs
of newly acquired operations and increased sales. As a percent of sales, costs
of goods sold increased from 69.3% to 71.5%, due to increased costs of raw
materials and energy, particularly in the fourth quarter, and an unfavorable mix
of business. See "Business -- History of Recent Acquisitions -- Continuing
Operations" above.

GROSS PROFIT. For the year ended August 31, 1999, gross profit from continuing
businesses increased by $6,269,000 to $32,776,000, an increase of 24% over the
gross profit generated during the prior fiscal year. The increase in gross
profit is due primarily to the inclusion of newly acquired operations. As a
percent of sales, the gross profit margin decreased from 30.9% for the year
ended August 31, 1998 to 30.7% for the year ended August 31, 1999, due primarily
to the inclusion of newly acquired operations, which had historically lower
gross margins. See "Business -- History of Recent Acquisitions -- Continuing
Operations" above.

For the year ended August 31, 2000, gross profit increased $2,500,000, or 8%,
over the prior fiscal year, primarily due to the inclusion of results of newly
acquired operations. See "Business -- History of Recent Acquisitions --
Continuing Operations" above. As a percent of sales, the gross profit decreased
from 30.7% to 28.5% due primarily to the inclusion to newly acquired operations,
with historically lower margins, for the complete fiscal year 2000 compared to a
partial fiscal year 1999. Other factors included several low margin OEM
arrangements, since terminated, and inflation in resin and manufacturing costs.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSE. For the year ended August 31, 1999,
selling, general and administrative expenses from continuing businesses
increased by $2,771,000, or 16%, compared to the prior fiscal year, due
primarily to the inclusion of several newly acquired operations, and continued
growth in sales and expenses. As a percent of sales, selling, general and
administrative expenses decreased from 20.0% to 18.6%, due mostly to the
inclusion of several newly acquired operations, which historically had lower
operating expenses as a percentage of sales. See "Business --History of Recent
Acquisitions -- Continuing Operations" above.

For the year ended August 31, 2000, selling, general and administrative expenses
("operating expenses") increased by $1,388,000, or 7%, primarily due to the
inclusion of newly acquired operations. See "Business -- History of Recent
Acquisitions -- Continuing Operations" above. As a percent of sales, operating
expenses decreased from 18.6% to 17.2%, as a result of the inclusion of newly
acquired operations, with historically lower operating expenses as a percentage
of sales, for the entire fiscal year 2000 compared to a partial fiscal year
1999, and as a result of more rapid sales growth than expense growth.

INTEREST EXPENSE, NET. Interest expense increased from $1,607,000 for fiscal
1998 and $2,280,000 for fiscal 1999 to $2,984,000 for fiscal 2000, due to
increased interest rates and higher average levels of debt during the year
although debt at August 31, 2000 was $1,303,000 less than at August 31, 1999.
Interest expense relates primarily to interest on debt owed to the Company's
primary lenders, pursuant to the borrowing arrangement described in the
"Liquidity and Capital Resources" section below. Most of the outstanding
borrowings under this arrangement were for acquisitions.

INCOME FROM CONTINUING OPERATIONS. As a result of the above described changes,
income from continuing operations increased by $1,997,000 in fiscal 1999 to
$6,555,000, an increase of 44% over fiscal 1998. Net income for fiscal 2000
increased by $751,000, or 11%.

EFFECTIVE TAX RATE. For the fiscal year ended August 31, 1999, the effective tax
rate, which is a composite of federal and state income taxes, decreased from
41.4% to 38.1%, due primarily to a lower effective combined state income tax
rate and increased foreign sales corporation tax benefit. For fiscal 2000 the
effective tax rate decreased to 33.6% primarily due to lower average state tax
rates and increased foreign sales corporation tax benefit. During the year, a
non-recurring tax benefit of $190,000 was recognized, reflecting the benefit of
state tax adjustments from prior periods. Without this non-recurring benefit,
the effective tax rate in fiscal 2000 would have been 35.3%. The foreign sales
corporation tax benefit provision of the U.S. Tax Code has been challenged by
the World Trade Organization and may be revised in the future. If the code were
changed to eliminate this benefit, the effective tax rate of the Company would
be approximately 2% higher.

INFLATION. Inflation did not have a significant impact on Summa's operations
during the past three fiscal years until fiscal 2000, particularly in the fourth
quarter. During that period, oil price increases resulted in increasing and
increasingly volatile costs of plastic resin, energy and transportation. These
factors did not have a material impact on the Company's financial results until
the fourth quarter, in which they contributed significantly to reduced gross
margins. To mitigate the future impact of inflation, the Company has recently
implemented selected price increases on certain of its products, and intends to
attempt to implement additional selected increases, although the ability to do
so is not certain. No significant amount of sales or purchases are made pursuant
to fixed price, long-term agreements.

SEGMENT INFORMATION. The following tables set forth the relative contribution of
each segment to the sales and operating income of the entire Company and the
operating margins of each segment. This data was derived from Summa's
consolidated statements of income for the three years ended August 31, 2000.

</TABLE>

From the foregoing discussion and above tables, it is apparent that the
Engineered Polymer Components segment comprises approximately 85% of the
Company's sales and virtually all of the Company's operating profit, and is
growing faster than the Extruded Plastic Products segment, a trend which is
expected to continue for the operations which currently comprise the Company.

Company in this Annual Report on Form 10-K.

LIQUIDITY AND CAPITAL RESOURCES

SOURCE AND USE OF FUNDS. The Company's primary source of liquidity has been cash
generated from operating activities and borrowings from third parties. See
"Financing Arrangements" below. During the three fiscal years ended August 31,
2000, net cash provided by operating activities was $8,441,000 in 1998,
$11,681,000 in 1999 and $8,368,000 in 2000. Cash flows from operations improved
in 1999 vs. 1998 primarily to the inclusion of newly acquired businesses. Cash
flows from operations declined in 2000 vs. 1999 due to increases in working
capital. Accounts receivable increased by $1.4 million and inventories increased
by $1.0 million, as accrued liabilities were reduced by $1.6 million.

Summa's principal uses of cash have been the (i) support of operating
activities, (ii) acquisitions of businesses, (iii) investment in capital
improvements, (iv) reduction of debt and (v) repurchase of common stock. Cash
used for certain investing activities for the three fiscal years ended August
31, 2000 is summarized in the following table:

<TABLE>

                                                                   Fiscal Years Ended August 31,
                                                                   -----------------------------

      Capital investment as a % of  depreciation.......        94.2%          104.1%          91.8%
</TABLE>

Increased levels of investment are a result of higher new product tooling
activity, manufacturing equipment upgrades and new computer systems. Although
Summa expects to continue making substantial investments in tooling for new
products, at August 31, 2000, Summa was not committed to any outside supplier
for major capital expenditures, and believes its present capacity, augmented by
anticipated continued investment in new product tooling and equipment, will be
sufficient to meet demand for its products. For information relating to
acquisitions, see "Business -- History of Certain Acquisitions -- Continuing
Operations" and "--- Recent Events " above.

WORKING CAPITAL; ASSET UTILIZATION. At fiscal year end August 31, working
capital was $10,854,000 in 1998, $10,326,000 in 1999, and $12,761,000 in 2000
representing a decrease of 5% from 1998 to 1999 and an increase of 24% from 1999
to 2000. Working capital decreased in 1999 in spite of increases in accounts
receivable and inventory associated with acquisitions, due to the increase in
the current portion of long-term debt of $3.1 million. The increase in working
capital in 2000 was primarily attributable to increased accounts receivable and
inventory due to sales growth and acquisitions.


                                      14

Asset utilization for the three fiscal years ended August 31, 2000 is
illustrated in the following table:

      Average inventory turnover..................     9.6 times      7.0 times      7.2 times
</TABLE>

The downward change in turnover of accounts receivable and inventory from 1998
to 1999 was not a result of changes in operations. It was a result of the
blending of newly acquired operations and the timing of acquisitions during
1999.

FINANCING ARRANGEMENTS. Summa has several debt relationships in place as
described below. Substantially all of the Company's assets are pledged to secure
debt. The term debt and revolving line of credit require compliance with various
bank covenants.

</TABLE>

Subsequent to the end of fiscal 2000, in October, Summa acquired the stock of
PSI. See "Business -- Recent Events", above. The acquisition facility was used
to finance the transaction.

Interest rates on bank debt, which are based on LIBOR and subject to market
fluctuation, are subject to reduction as the Company achieves certain financial
milestones or increase due to market conditions. See also Note 9 in the "Notes
to Consolidated Financial Statements" of the Company in this Annual Report on
Form 10-K.

The Company announced a stock buy-back program September 28, 1998, under which
it was authorized to purchase its common stock in an aggregate amount of up to
$2,000,000. During fiscal 1999, the Company repurchased and retired 18,000
shares of its common stock in block trades, at an average price of $8.48 per
share. Additionally, the Company acquired and retired 10,046 shares of its stock
at $12.57 per share and 2,084 shares at $14.06 directly from certain former
employees who received distributions from the Summa Industries Employee Stock
Ownership Plan upon their retirement. During fiscal 2000, the Company
repurchased and retired 124,944 shares of its common stock at an average price
of $10.96 per share and repurchased all of the outstanding warrants to acquire
its common stock for $500,000. In addition, the Company acquired and retired
9,104 shares of its stock at $11.25 per share from a former employee who retired
and received the distribution from the Summa Industries Employee Stock Ownership
Plan upon retirement. As of August 31, 2000, the authorized repurchase amount of
$2,000,000 had been fully utilized.

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 4,224,715
shares were outstanding at August 31, 2000 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.

See Note 1 in the "Notes to Consolidated Financial Statements" in Part IV of
this Annual Report on Form 10-K.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Report of Independent Public Accountants


TO:      The Board of  Directors and Stockholders of Summa Industries:


We have audited the accompanying consolidated balance sheets of Summa
Industries (a Delaware corporation) and subsidiaries as of August 31, 1999
and 2000 and the related consolidated statements of income, stockholders'
equity and cash flows for each of the three years in the period ended August
31, 2000. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the
financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Summa Industries and
subsidiaries as of August 31, 1999 and 2000, and the results of their
operations and their cash flows for each of the three years in the period
ended August 31, 2000, in conformity with accounting principles generally
accepted in the United States.

Summa Industries
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For the year ended August 31, 2000

1.        DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

Summa Industries, a Delaware corporation ("Summa" or the "Company"), develops
and manufactures proprietary plastic products for diverse industrial and
commercial markets, primarily located in the United States.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of Summa and its
wholly-owned subsidiaries. The results of operations of acquired companies
have been included in the consolidated statements of income and cash flows of
the Company since the dates of acquisitions. See Note 17. All intercompany
account balances and transactions have been eliminated in consolidation.
Prior year amounts in the accompanying financial statements have been
reclassified to conform with current year presentations.

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

The preparation of financial statements in conformity with United States
generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date
of the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

REVENUE RECOGNITION

Revenue from product sales is recognized at the time of shipment.

INVENTORIES

Inventories are stated at the lower of cost (determined on a first-in,
first-out basis) or market. Cost includes material, labor and manufacturing
overhead.

PROPERTY, PLANT AND EQUIPMENT

Depreciation is charged against earnings, principally using the straight-line
method, over the estimated useful lives of the related assets as follows:

<TABLE>
                  <S>                                <C>
                  Building and improvements          10-40 years
                  Machinery and equipment            3-10 years
                  Office furniture and equipment     3-7 years
                  Leasehold improvements             Lesser of remaining term
                                                     of lease or estimated
                                                     useful life
</TABLE>

Maintenance, repairs and minor renewals are charged directly to expense as
incurred. Additions and improvements to property, plant and equipment are
capitalized. When assets are disposed of, the related cost and accumulated
depreciation thereon are removed from the accounts, and any gain or loss is
included in operations.

INTANGIBLE ASSETS

Intangible assets include goodwill and other intangibles such as trade names,
patents and customer lists recognized in connection with business
acquisitions. Goodwill is amortized over 15-40 years. Other intangibles are
being amortized over their estimated useful lives of 10-17 years. See Note 7.

LONG-LIVED ASSETS

The Company has adopted the Statement of Financial Accounting Standards (SFAS)
No. 121, "Accounting for the Impairment of Long-Lived Assets and Long-Lived
Assets to be Disposed of". This statement establishes accounting standards for
the impairment of long-lived assets, certain identifiable intangibles, and
goodwill related to those assets to be held and used and for long-lived assets
and certain identifiable intangibles to be disposed of. Management monitors the
recoverability of existing assets and considers events or changes in
circumstances, such as loss of significant customers, which indicates that the
value of assets may not be recoverable. When circumstances indicate possible
impairment, management compares the carrying value of existing assets to
management's best estimate of undiscounted future cash flows expected to result
from the use of the assets and their eventual disposition. If such assets are
considered to be impaired, the impairment to be recognized is measured by the
amount by which the carrying value of the assets exceeds the estimated fair
value of the assets. Estimated fair value will be based on either reliably
determined third-party valuations, if available, or discounted cash flows. When
using discounted cash flows, a discount rate will be selected which will be
commensurate with the risk involved. No impairment has occurred as of August 31,
2000.

EARNINGS PER COMMON SHARE

Basic earnings per common share (EPS) is based on income available to common
stockholders divided by the weighted average number of common shares outstanding
during the year. Diluted EPS is similar to the computation for Basic EPS except
that the denominator is increased to include the number of additional common
shares that would have been outstanding if the dilutive potential common shares
had been issued. See Note 2 for details of the computation.

CASH EQUIVALENTS

The Company considers all highly liquid debt instruments with an original
maturity of three months or less to be cash equivalents.

INCOME TAXES

The Company accounts for income taxes in accordance with the SFAS No. 109
"Accounting for Income Taxes". This statement requires that income taxes be
accounted for using the liability method.

STOCK-BASED COMPENSATION

The Company has elected to continue to report stock based compensation to
employees and directors in accordance with Accounting Principles Board (APB)
Opinion No. 25, "Accounting for Stock issued to Employees." The Company has
adopted the appropriate disclosure requirements of SFAS No. 123, "Accounting for
Stock-Based Compensation." See Note 12.

COMPREHENSIVE INCOME

There are no adjustments to net income required in order to derive comprehensive
income.

RECENT ACCOUNTING PRONOUNCEMENT

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and for Hedging Activities," which establishes standards for
reporting and disclosure of derivative and hedging instruments. SFAS No. 137,
"Deferral of the Effective Date of FASB Statement No. 133," requires SFAS No.
133 to be adopted for all fiscal quarters of all fiscal years beginning after
June 15, 2000. The Company has not yet adopted SFAS No. 133, but if it had been
adopted, there would not have been any effect on reported income because the
Company had not entered into any derivative or hedging financial contracts. The
Company plans to adopt SFAS No. 133 in fiscal year 2001.

In December 1999, the Securities and Exchange Commission issued Staff Accounting
Bulletin No. 101, "Revenue Recognition in Financial Statements" ("SAB 101"). SAB
101 clarifies certain existing accounting principles for the recognition and
classification of revenues in financial statements. The Company will adopt SAB
101 during the first quarter of fiscal 2001. The Company does not believe that
the adoption of SAB 101 will have a material effect on operations or financial
position.

1999 and 203,708 common shares in 2000 were not included in the computation of
diluted earnings per share because the exercise price was greater than the
average market value of the common shares.

4.   DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used to estimate the fair value of
each class of financial instrument for which it is practicable to estimate:

     Cash and cash equivalents, accounts receivable and accounts payable - the
     carrying amount is a reasonable estimate of fair value.

     Long-term debt - the carrying value approximates fair value since the
     interest rate on the long-term debt approximates the rate which is
     currently available to the Company for the issuance of debt with similar
     terms and maturities.

The Company has adopted a retirement and savings plan. The plan, which qualifies
under Section 401(k) of the Internal Revenue Code, allows employees to defer
specified percentages of their compensation, in a tax-deferred trust. The
Company may elect to make matching contributions and discretionary
contributions. The cost of the Company matching contribution is partially offset
by a reduction in payroll taxes. Company contributions to the plan totaled
$529,000 in 1998, $699,000 in 1999 and $741,000 in 2000.

The Company has adopted an Employee Stock Ownership Plan (the "ESOP"). Under the
ESOP, the Company may make contributions to the ESOP trust for purchases of
shares of the Company's Common Stock, or may contribute Common Stock directly to
the ESOP trust. The total cash contributions by the Company to the ESOP were
$180,000 in 1998, $278,000 in 1999 and $325,000 in 2000.


                                      F-12

The Company has various employment agreements with officers, some of which
include bonuses, stock options, and/or change in control provisions.

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.

11.  RELATED PARTY TRANSACTIONS

The Company is obligated to pay fees and commissions on certain products to one
of its directors, pursuant to pre-existing agreements with a subsidiary acquired
in fiscal 1997. Total fees and commissions were $150,000 in 1998, $172,000 in
1999 and $204,000 in 2000. The agreements continue until 2009.

12.  STOCK-BASED COMPENSATION PLANS

The Company has four stock option plans (the Plans) which have been approved by
the Stockholders and are administered by its Board of Directors. Under the
Plans, options to acquire shares of common stock may be granted to key
employees, directors, consultants, vendors and others in the following amounts:

In addition, options have been issued in conjunction with acquisitions. The fair
value of these options is included in the purchase prices.

The Company accounts for stock options issued to employees and directors under
APB Opinion No. 25. Under APB 25, if the exercise price of the stock option
equals the market price of the underlying stock on the issuance date, no
compensation expense is recognized. Consequently, no compensation expense was
recognized under these plans for fiscal years 1998, 1999 and 2000. The Company
is required by SFAS No. 123 "Accounting for Stock-Based Compensation" to provide
pro forma disclosures under an alternate fair value method of accounting.

Had compensation cost for stock options awarded under these plans been
determined consistent with SFAS Statement No. 123, the Company's net income and
earnings per share would have reflected the following pro forma amounts at
August 31:

Under these Plans, the options are generally issued with exercise prices
equal to the market price of the Company's stock on the grant date. Options
vest cumulatively over various periods, at the discretion of the Board of
Directors, up to five years from the grant date, are exercisable in whole or
in installments, and expire up to ten years from date of grant. Options that
are forfeited are again available for grant under the Plans. All options vest
in full immediately prior to a change in control of the Company, as defined
in the stock option plans.

A summary of the status of the Company's stock options at August 31, 1998, 1999

14. SEGMENT REPORTING

Effective September 1, 1998, the Company adopted SFAS No. 131, "Disclosures
about Segments of an Enterprise and Related Information", which establishes
revised standards for the manner in which public business enterprises report
information about operating segments.

The Company identifies its reportable segments based on similarities between
economic characteristics considering products, production processes, customers
and distribution. The Company's operations consist of two businesses segments -
Engineered Polymer Components and Extruded Plastic Products.

In the Engineered Polymer Components segment, the Company designs and
manufactures, primarily by injection molding, sophisticated components, most of
which are proprietary. Many of the components are patented and/or approved by
government agencies such as the USFDA, or independent laboratories such as
Underwriters' Laboratories. The materials used in the manufacture are generally
known as engineered or high performance plastics. Most of the sales of the
components are made directly by Company employees to original equipment
manufacturers who incorporate the components into their products.

In the Extruded Plastic Products segment, the Company continuously extrudes
plastic products, which are generally not differentiated from those of
competitors and are typically produced from materials known as commodity grade
plastic resins. Extruded Plastic Product sales are made primarily through
independent distribution channels.

                                     F-16

<PAGE>

On June 26, 1998, the Company completed the divestiture of its subsidiary,
GST Industries, Inc. Accordingly, this business unit has been accounted for
as a discontinued operation and the results of its operation are segregated
in the accompanying consolidated statements of income. There was no gain or
loss on the disposition of GST and no interest expense was allocated to
discontinued operations for fiscal year 1998. Discontinued operations have
not been segregated in the consolidated statements of cash flows. The
preceding notes to consolidated financial statements have been revised, as
necessary, to reflect the change in reporting due to discontinued operations.
Sales from discontinued operations were $2,818,000 and income from
discontinued operations, net of the effect of income tax was $316,000, in
fiscal year 1998.

17.    ACQUISITIONS

On October 28, 1997, the Company completed the acquisition of Calnetics
Corporation ("Calnetics"). The total acquisition cost was $31,792,000,
consisting of cash due to former Calnetics shareholders of $22,335,000, (of
which $243,000 was due at August 31, 1998) acquisition costs of $50,000,
liabilities assumed or incurred of $8,062,000 and an estimated fair value of
$1,345,000 for options issued in conjunction with the transaction, primarily
replacement options issued to Calnetics employees who continued with the
Company. The acquisition 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. During
fiscal year 2000, an insurance claim settlement was received which resulted
in a reduction of the acquisition cost and of goodwill in the amount of
$350,000. The excess of the adjusted purchase price over the fair value of
the net assets acquired amounted to $13,624,000 and has been recorded as
goodwill which is being amortized on a straight-line basis over 40 years.

On May 1, 1998, the Company completed the acquisition of Falcon Belting, Inc.
("Falcon"), a manufacturer of modular plastic conveyor belting used in food
processing industries. The total acquisition cost was $5,125,000, consisting
of $2,636,000 in cash and the present value of obligations to make future
payments to the former owner of Falcon and liabilities assumed or incurred of
$2,489,000. The acquisition was 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. During
fiscal year 1999, a contingency was resolved which resulted in a reduction of
the total acquisition cost and of goodwill in the amount of $125,000. The
excess of the adjusted purchase price over the fair value of the net assets
acquired amounted to $1,870,000 and has been recorded as goodwill which is
being amortized on a straight-line basis over 30 years.

On March 5, 1999, the Company completed the acquisition of substantially all
of the assets of Plastron Industries, L.P. ("Plastron"). The aggregate
purchase price paid for Plastron consisted of (i) $19,525,000 in cash; (ii) a
four-year warrant exercisable to purchase up to 200,000 shares of the
Company's common stock at $11.75 per share valued at $278,000; (iii)
investment banking fees consisting of a $125,000 cash payment and stock
options, valued at $32,000; and (iv) the assumption of certain liabilities,
principally trade payables and accrued obligations of $2,220,000. 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 values of the net assets acquired amounted to
$13,781,000 and has been recorded as goodwill which is being amortized on a
straight-line basis over 35 years.

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 $2,143,000 in cash, 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
net fair market value of 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 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 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 net fair market value of acquired assets was $100,000 and has been
recorded as goodwill, which is being amortized on a straight-line basis over
15 years.

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
continuing businesses of the Company with Calnetics and Plastron as though
the acquisitions had been made as of September 1, 1997. Pro forma adjustments
have been made to give the effect to the amortization of goodwill and other
intangibles, adjustments in depreciation and inventory value, interest
expense related to acquisition debt, the related tax effects and the effect
upon basic and diluted earnings per share of the additional shares of stock
given in exchange for LexaLite stock and of stock options and warrants issued
in conjunction with the acquisitions. The following pro forma financial
information does not include adjustments to give effect to the Falcon,
Broadview and Yarbrough-Timco acquisitions as such adjustments would not be
material.
