ITEM 1.   BUSINESS.

General
- -------

     Summa Industries ("Summa") was incorporated in the State of California in
1942, and is 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 traded on The Nasdaq National Market under the symbol "SUMX". Through
1990, the principal business of Summa was limited to the design, manufacture and
sale of chemical process equipment. In 1991, Summa adopted a strategy of growth
through acquisitions and has completed four major acquisitions, including the
recent purchase of Calnetics Corporation on October 28, 1997. See "Growth
Through Acquisitions Strategy" and "Acquisition of Calnetics" below.
Consequently, as of October 28, 1997, the primary business and operations of
Summa are conducted through six operating subsidiaries that are wholly-owned,
directly or indirectly, by Summa. Through these subsidiaries, Summa designs and
manufactures injection-molded plastic optical components for OEM customers in
the lighting industry, molded plastic bobbins, components, filters, fittings,
sheet and tubing primarily for the industrial plastics, building materials and
agricultural irrigation industries, material handling components, some of which
Summa initially developed in plastic, including plastic chains, belts and
customized components, water cannons for fire fighting in harsh environments,
and proprietary pneumatic/hydraulic actuators and other components for defense
aircraft.

     The principal executive offices of Summa are located at 21250 Hawthorne
Boulevard, Suite 500, Torrance, California 90503, its telephone number is (310)
792-7024, and its facsimile number is (310) 792-7079.

GROWTH THROUGH ACQUISITIONS STRATEGY
- ------------------------------------

     Through 1990, the principal business of Summa was limited to the design,
manufacture and sale of chemical process equipment, which was unprofitable from
1983 to 1990, in which year it had revenues of only $3,257,000. In 1991, Summa
adopted 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 shareholders by increasing
the number of outstanding shares in the public float and the trading activity in
the stock. Typically, it is expected that Summa's corporate staff will not
direct operations of the acquired subsidiaries on an ongoing basis, but, in
addition to planning and financial oversight, will provide financing, conduct
the acquisition program and business development activities, and handle investor
relations matters. From time to time, the corporate staff also will be active in
non-operational business activities such as risk management and employee benefit
program management. Corporate charges are assessed on a basis established
annually, related to asset utilization by each operating subsidiary.

     The first acquisition consummated by Summa following the adoption of this
strategy occurred in October 1991, when Summa purchased all of the outstanding
capital stock of GST Industries, Inc., a California corporation ("GST"). GST has
two divisions, the Stang Industrial Products Division ("Stang") which
manufactures and sells water cannons for firefighting, and the GST Industries
Division which manufactures and sells proprietary sub-systems and components for
the defense aircraft industry, primarily for the F-16 and derivative aircraft.
Summa paid the GST shareholders an aggregate of $2.3 million in cash and gave
them subordinated promissory notes in an aggregate principal amount of $200,000,
with interest only payable thereon at the rate of 10% per annum at the end of
the first and second years, and all principal payable at the end of the second
year following the closing. In addition, the former shareholders of GST earned
contingent performance payments totaling $2,111,000. The acquisition was
partially funded by borrowings under Summa's then existing credit facility with
Community Bank, which were subsequently repaid.

                                       2
<PAGE>
 
     In July 1993, Summa acquired all of the outstanding capital stock of KVP
Systems, Inc., a California corporation ("KVP"), which designs, manufactures and
markets material handling components, including 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 was issued to the
shareholders of KVP in a transaction registered under the Securities Act of
1933, as amended (the "Securities Act"). In addition, Karl V. Palmaer, the
founder of KVP, joined the Board of Directors of Summa.

     On November 22, 1996, Summa acquired all of the outstanding capital stock
of LexaLite International Corporation, a Delaware corporation ("LexaLite"),
through the merger of a newly formed and wholly-owned subsidiary of Summa with
and into LexaLite in which 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.
Because LexaLite operates as a wholly-owned operating subsidiary of Summa,
headquartered in Charlevoix, Michigan, the achievement of most of the perceived
advantages of this acquisition will not be measured by the ability of the
combined companies to eliminate overlapping facilities or personnel or achieve
other efficiencies or economies of scale. Rather, the success of the acquisition
will depend more on the continuing compatibility of the management of both Summa
and LexaLite. It is anticipated, however, that a number of administrative issues
such as tax and legal, personnel policies and shareholder relations will be
handled primarily at the Summa level, thereby permitting the management of
LexaLite to devote more time and attention to sales and marketing, product
development and customer service. There can be no assurance that there will be
future changes in LexaLite's operations, marketing or sales, or that the other
perceived benefits of the acquisition will be realized.

     On October 28, 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
in which the former shareholders of Calnetics received an aggregate of
approximately $22,335,000 in cash and Summa assumed approximately $1.8 million
in indebtedness. In this acquisition, Summa also acquired the following
operating subsidiaries of Calnetics: Manchester Plastics Co., Inc. ("Manchester
Plastics"), a California corporation that manufactures proprietary items and
custom products of acrylic, polycarbonate and polystyrene plastic sheet,
principally for the building materials and industrial plastics industries; Ny-
Glass Plastics, Inc. ("Ny-Glass"), a California corporation that 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 Agricultural Products, Inc. ("API"), a California
corporation that manufactures fittings, filters, plastic tubing and accessories,
principally for irrigation use in the agricultural industry. For additional
information concerning this acquisition and the business and operations of
Calnetics, see Item 1, "Business - Acquisition of Calnetics" and Item 7,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations - Acquisition of Calnetics," below.

     In evaluating future acquisitions, Summa will endeavor to identify target
companies that manufacture engineered plastic components or other industrial
products which have a proprietary advantage because of patent protection, brand
recognition, unique manufacturing requirements 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 intended that each acquired company will be maintained as a
separate operating unit in most instances, 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
continuing day to day 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 12 months of the
closing can reasonably be expected.

     Continued implementation of Summa's strategy for growth through
acquisitions will depend to a significant extent upon the ability of Summa's top
management in identifying appropriate candidates for 

                                       3
<PAGE>
 
acquisition, negotiating deals acceptable to the Board of Directors of Summa and
the shareholders of Summa, and supervising the management of a variety of
operating subsidiaries. Furthermore, with a developing focus on businesses which
manufacture engineered plastic components, the number of opportunities which
meet this acquisition criteria will be smaller. In addition, with the increased
size of Summa, larger acquisition candidates will have to be sought in the
future to sustain the growth rate of Summa and the number of such candidates
will be 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. 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.

PRODUCTS
- --------

     The principal products offered by Summa through the three operating
subsidiaries owned prior to the acquisition of Calnetics include engineered
injection-molded plastic optical components for OEM customers in the lighting
industry produced by LexaLite, plastic conveyor components manufactured by KVP,
industrial firefighting equipment produced by Stang, and aerospace assemblies
fabricated by GST. For related information regarding Calnetics, see "Acquisition
of Calnetics" below.

     PLASTIC OPTICAL COMPONENTS. Summa's optical components business is
conducted by LexaLite, which is headquartered in Charlevoix, Michigan.
LexaLite's original products were plastic lamp covers for street lights, used to
replace glass covers which were subject to vandalism. Subsequently, LexaLite
developed prismatic lenses, refractors and reflectors molded 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. On
a selective basis, LexaLite also makes non-optical molded plastic products. Most
of the products are injection molded from optical grade polycarbonate or
acrylic. The principal advantages of LexaLite's injection molded plastic
components over more traditional glass or metal components are lighter weight,
superior optical performance and in certain instances, lower cost.

     PLASTIC CONVEYOR COMPONENTS. Summa's material handling components business
is conducted by KVP, located in Rancho Cordova, California, whose products are
engineered plastic components which form conveyer belts and chains. The
components in KVP's product line, several 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 are
available in materials which can withstand temperatures ranging from 150 degrees
Fahrenheit below zero to 350 degrees Fahrenheit, a temperature typically
required for sterilization. The components do not require lubrication and thus
offer the advantage of operation free from contaminants such as grease, oil and
metal particles. Because KVP's 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.

     INDUSTRIAL FIREFIGHTING EQUIPMENT. Summa's industrial firefighting business
is conducted by Stang, located in Santa Ana, California, whose products have
been sold in the market for over 20 years. Stang designs, manufactures and sells
monitors, also known as water cannons, that are used for firefighting and to
disperse toxic gas clouds, as well as in hydraulic mining and digester cleaning.
These monitors are designed to equalize reactive forces so that the monitors can
be aimed with minimal force. Summa believes that Stang has proprietary designs
which provide superior performance to products offered by competitive
manufacturers. Stang monitors can be mounted on vehicles, standpipes, hydrants
or vessels, including fireboats, and can be controlled manually or hydraulically
via remote actuators provided by Stang as options.

     AEROSPACE ASSEMBLIES. Summa's aerospace business is conducted by GST,
located in Santa Ana, California. GST has been in the business of designing,
manufacturing and selling hydraulic actuators and other parts and sub-assemblies
for use in aircraft such as the F-16 and similar activities for more than 20
years.

RESEARCH AND DEVELOPMENT
- ------------------------

     Through its subsidiaries, Summa invests significantly in the development of
products for new applications. Only direct costs associated with tooling for new
products are capitalized. All other costs, including salaries and wages of
employees included in research and development, are expensed as incurred. Most
of Summa's research and development efforts are for engineered plastic
components. For related information regarding Calnetics, see "Acquisition of
Calnetics" below.

     Summa's LexaLite subsidiary consistently invests heavily in research and
development of products and manufacturing methods. LexaLite independently
develops many products for sale to multiple customers, and also develops
products to specifications with customers on a confidential basis, which may
provide for sales by the customer on an exclusive basis or for a license to
LexaLite to make sales to third parties. For the years ended June 30, 1995, 1996
and 1997, LexaLite spent $671,000, $885,000 and $525,000, respectively, on
research and development. At its state-of-the-art Lighting Research Center,
which was recently consolidated into the LexaLite Scientific Center building,
optical surfaces are designed using computer-aided design techniques, prototypes
of products are fabricated, and photometric performance testing is conducted.
The LexaLite Scientific Center was created in 1994 to develop confidential
products and methods. LexaLite is also developing an automated thin film coating
process, which has the potential to materially reduce the cost and increase the
photometric performance of plastic "canister" components to be used in recessed
lighting fixtures. If successful, this product could result in a significant
increase in LexaLite's sales because these components are generally made of
metal by others.

PRODUCTION; ENVIRONMENTAL MATTERS
- ---------------------------------

     Summa's principal manufacturing operation is injection molding of plastic
parts. Some products are molded by third-party vendors. Summa performs
additional production operations including machining and welding of both metal
and plastic parts, coating, assembly and testing. Most of Summa's production
takes place in company-owned LexaLite plants in the states of Michigan and
Tennessee.

     Certain injection molds and tools are made by a division of LexaLite at the
main plant, where the staff has developed the injection molding capability to
produce specialized optical components using the complex tooling required for
the manufacture of injection molding to close tolerances. Products are made on
modern molding machines which range from 28 to 1500 tons clamping force.
Ancillary equipment and special operations include automatic resin feed systems,
two color molding, insert molding, robotics, painting, vacuum deposition coating
with reflective metallic films, assembly, packaging and warehousing. LexaLite
operates on a just-in-time system with many of its customers, and inventories
are managed to minimal levels. Inventory turns approximately 17 times a year.
All of LexaLite's manufacturing plants are ISO 9002 registered. LexaLite
monitors environmental compliance via a full-time environmental engineer,
reporting directly to a vice-president.

     Summa management believes that Summa is in compliance with all requirements
set forth by the E.P.A. and the states of California, Michigan and Tennessee
relating to air quality, water quality and hazardous waste management and
disposal. For related information regarding Calnetics, see "Acquisition of
Calnetics" below.

MARKETING
- ---------

     Summa's plastic lighting components manufactured by its LexaLite subsidiary
are installed in high-bay manufacturing plants, warehouses, retail stores,
gasoline stations, other types of buildings, parking lots, traffic signals,
marine navigation aids and in vehicles. Because the products are components,
they are virtually always sold to OEM manufacturers such as Hubbell, Lithonia
division of National Service Industries, Inc., Cooper, Thomas Industries and GE,
as well as many less recognized companies, many of whom have been active
accounts for more than 10 years. At August 31, 1997, LexaLite had 375 active
accounts. Sales to the largest five customers represented 12.2%, 11.1%, 7.5%,
6.1% and 2.8% of product and tooling sales, respectively, for the nine months
ended August 31, 1997. Product sales comprised 95% and tooling sales accounted
for 5% of LexaLite's net sales during the nine months ended August 31, 1997.
LexaLite seeks to maintain a "strategic partnership" relationship 

                                       5
<PAGE>
 
with its customers and has a direct sales force of seven persons who operate out
of two manufacturing plants in Michigan and Tennessee. Sales of all optical
components are considered strategic, while non-optical products are manufactured
to expand the relationships with customers or to balance utilization of
manufacturing capacity. LexaLite also sells its products through commissioned
sales representatives in selected domestic and international geographic areas
and for specialized business situations. For the nine months ended August 31,
1997, approximately 83% of LexaLite's sales were made directly and approximately
17% of its sales were made through commercial manufacturers' representatives. Of
LexaLite's product sales during the nine months ended August 31, 1997,
approximately 54% of sales were of products made from LexaLite proprietary
tooling, approximately 31% were of optical components manufactured for a single
customer using tooling owned by others, and approximately 15% of product sales
were of non-optical components.

     Ultimate users of material handling components in the food processing
industry manufactured by Summa's KVP subsidiary include companies such as
Beatrice/Hunt Wesson, Campbell Soup, Comstock Food, Kellogg's and Jeno's. In
bakery applications, the ultimate users include Sara Lee, Pepperidge Farms and
Lenders. In poultry applications, ultimate users include Foster Farms, Tyson
Foods, Pilgrims Pride and Con Agra. In freezing applications, ultimate users
include Baskin Robbins, Tombstone Pizza, Stouffer's and Swanson's. The
components also have applications in the pharmaceutical, industrial and
electronics industries. Summa's GST subsidiary sells aerospace assemblies,
primarily for the F-16 and derivative aircraft, to a foreign government engaged
in a U.S. sanctioned cooperative aircraft manufacturing program, Lockheed
Aircraft, and the U.S. Department of Defense. The primary markets for Summa's
Stang subsidiary products are the oil, gas and petrochemical industry,
municipalities which use fireboats, the mining industry and the municipal waste
water treatment industry. Products are sold directly and through independent
representatives and distributors, world-wide. Summa does not believe that
revenues attributable to sales of any of the products manufactured by its
industrial firefighting equipment or material handling components subsidiaries
are dependent upon sales to one or a small number of customers, although in a
given year one or a small number of customers may account for a significant
portion of sales. In the fiscal year ended August 31, 1997, the largest customer
in either segment accounted for 2% of consolidated net sales, while in fiscal
years 1996 and 1995 sales to a single customer accounted for 5% and 7% of total
consolidated net sales, respectively. Because the F-16 is a mature program which
is being phased out, GST faces a possible loss of most of its defense related
business over the next several years. Sales of aerospace assemblies represented
15%, 15% and 4% of Summa's consolidated net sales for 1995, 1996 and 1997,
respectively, with sales of aerospace assemblies to GST's largest customer
constituting 7%, 6% and 2% of consolidated net sales for the three most recently
completed fiscal years.

RAW MATERIALS
- -------------

     Summa's KVP and Stang subsidiaries purchase materials and parts, including
pelletized plastic resins, castings, forgings, steel, valves and controls from
various suppliers. Summa does not believe that either of these subsidiaries is
dependent upon any single supplier or manufacturer for any of its present
principal requirements for materials or parts, and neither experienced
significant difficulty in obtaining such parts and materials during the fiscal
year ended August 31, 1997. Lead times for special components, such as custom
hydraulic power units, can be as long as four months. Summa's LexaLite
subsidiary purchases pelletized resins from major suppliers such as Bayer, GE
Plastics, ICI and others. Certain of these resins may be in short supply from
time to time, but LexaLite has been able to obtain an adequate supply of resin
during such periods to meet its manufacturing commitments, because it is a
significant consumer of the materials. LexaLite believes it is one of the
largest users of optical grade polycarbonate and acrylic in the world.
Occasionally, LexaLite uses smaller quantities of other resins such as ABS,
polypropylene and nylon. For related information regarding Calnetics, see
"Acquisition of Calnetics" below.

BACKLOG
- -------

     On August 31, 1997, Summa's continuing businesses had a backlog of orders,
believed to be firm, in the amount of $6,323,000, as compared to a backlog of
$2,475,000 as of August 31, 1996. Of the backlog at August 31, 1997, $3,524,000
was attributable to orders for plastic optical components manufactured by
LexaLite, $418,000 was attributable to orders for KVP's material handling
components, $358,000 was attributable to orders for Stang

                                       6
<PAGE>
 
firefighting equipment, and $1,343,000 was attributable to orders for aerospace
assemblies produced by GST. A portion of Summa's August 31, 1997 backlog
consisted of products to be manufactured to custom designs suited for a
particular customer's application or physical requirements. Because the length
of time between entering an order, shipping the product and recording a sale can
vary significantly from product to product, Summa believes that its backlog
levels should not necessarily be relied upon as an indicator of sales volume for
a specific future period. The aerospace assembly backlog is comprised of some
long-term contracts, which are scheduled to ship through 1999. Since LexaLite's
lead time for producing components is only two to four weeks, backlog
historically has been minimal and typically represents approximately one and 
one-half months of product sales. The backlog of orders for tooling, as opposed
to products, varies widely with the lead time ranging from four to ten months.
At August 31, 1997, the backlog of firm orders for new tooling was $680,000,
approximately 6 months of fiscal 1997 tooling sales. For related information
regarding Calnetics, see "Acquisition of Calnetics" below.

COMPETITIVE CONDITIONS
- ----------------------

     The markets for the products currently manufactured and sold by each of
Summa's operating subsidiaries are characterized by extensive competition. There
are a number of companies that currently offer competing products nationally and
internationally, and in certain geographic areas from local manufacturers. 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. A significant number
of custom injection molders, some of which are larger than Summa's LexaLite
subsidiary, make optical components. Management believes that none of these
companies regards optical components as a strategic business focus and none has
developed optical design expertise to a significant extent. On the other hand,
virtually all of LexaLite's customers have both optical design capability and
injection molding machines and also conduct operations for themselves which
LexaLite regards as within its strategic activity.

     Summa believes that its trade names and reputation are significant to its
competitive position in all segments. In addition, Summa believes that price is
a significant element of competition in all segments. 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. Summa'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
Summa's products noncompetitive. For related information regarding Calnetics,
see "Acquisition of Calnetics" below.

PATENTS, TRADEMARKS AND LICENSES
- --------------------------------

     Summa holds several domestic and foreign patents on products which it has
developed or acquired that expire on dates ranging from the near term to 2010.
In addition, several active patent applications are being processed. The extent
to which patents provide a commercial advantage or inhibit the development of
competing products varies. To a large extent, however, Summa is required to rely
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 foreign and domestic trade name and
trademark registrations covering the names and logos which appear on its product
which, in the opinion of management, are helpful in enabling Summa to maintain
its present competitive position. For related information regarding Calnetics,
see "Acquisition of Calnetics" below.

EMPLOYEES
- ---------

     At August 31, 1997, Summa had 357 employees, including three employees who
comprise Summa's corporate staff, 85 salaried and 169 hourly employees at
LexaLite, including 11 involved in sales and marketing, 205 in manufacturing and
38 in general administration, 70 employees at KVP, of whom 16 were involved in
sales and marketing, 44 in manufacturing and 10 in general administration, and
30 employees at GST, of whom 4 were involved in sales and marketing, 22 in
manufacturing and 4 in general administration. LexaLite's headquarters is
located in a small town in Northwest Michigan that has a limited labor pool, and
LexaLite is one of the largest employers in the area. Occasionally, LexaLite has
had to recruit individuals for key positions from outside the area and has
incurred some delays in filling these positions. In 1985, LexaLite opened a
branch plant near Nashville, Tennessee, in an area which, at the time, had a
labor surplus. Subsequently, a number of other employers have opened plants in
that area and management currently does not consider a labor surplus to exist
there. No employees of any of Summa's operating subsidiaries are covered by a
collective bargaining agreement. Summa considers its relationship with its
employees to be good. For related information regarding Calnetics, see
"Acquisition of Calnetics" below.

ACQUISITION OF CALNETICS
- ------------------------

     On October 28, 1997, Summa acquired all of the outstanding capital stock of
Calnetics through a merger of a newly formed and wholly-owned subsidiary of
Summa with and into Calnetics in which the former shareholders of Calnetics
received an aggregate of approximately $22,335,000 in cash and Summa assumed
approximately $1.8 million in indebtedness.

     Accordingly, as of October 28, 1997, Calnetics, a California corporation
founded in 1960, whose headquarters are located at 20401 Prairie Street,
Chatsworth, California 91311, became a wholly-owned subsidiary of Summa. All of
the manufacturing operations of Calnetics are conducted through its three 
wholly-owned subsidiaries: Manchester Plastics located in Chatsworth,
California, that manufactures proprietary items and custom products of acrylic,
polycarbonate and polystyrene plastic sheet, principally for the building
materials and industrial plastics industries; Ny-Glass located in Corona,
California, that 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 API, with locations in
Ontario, California and Winter Haven, Florida, that manufactures fittings,
filters, plastic tubing and accessories, principally for irrigation use in the
agricultural industry.

     Prior to the acquisition by Summa, the outstanding common stock of
Calnetics was registered under Section 12(g) of the Exchange Act and traded on
The Nasdaq National Market under the symbol, "CALN." Set forth below is
additional information concerning the business and operations of Calnetics which
has been derived from the Annual Report on Form 10-K for the year ended June 30,
1997 filed by Calnetics under the Exchange Act:

     PRODUCTION.  Through its three operating subsidiaries, the principal
manufacturing operations of Calnetics are the extrusion of plastic sheet and
tubing and injection and structural foam molding of numerous plastic parts using
various types of resins. Through API, Calnetics also assembles certain parts
using sonic welding techniques. Although substantially all extrusions are
performed in-house by Calnetics, a material amount of injection molding of
plastic parts is performed by third parties, principally for API. Although
Calnetics designs, repairs, services and 

                                       8
<PAGE>
 
maintains molds for its own products and those of its customers, it does not
perform mold-making services. In addition to the extrusion of sheet and tubing
and the injection molding of clear and colored plastic parts, Calnetics performs
a variety of value-added services, such as pin-insertion, heat stamping, silk
screening, assembly, packaging and short-term warehousing.

     For its fiscal year ended June 30, 1997, approximately 70% of Calnetics'
net sales of approximately $36.6 million were of proprietary products. The
remaining portion of net sales for such fiscal year were of custom fabrication
and production parts manufactured to each individual customer's specifications.
Such custom parts are produced for a wide variety of industries, including the
electronics industry.

     All production occurs at plants located in Chatsworth, Corona and Ontario,
California and in Winter Haven, Florida. Sheet products are made on extrusion
lines located at the Manchester Plastics plant. Tubing is made on extrusion
lines located at API's two plants, while the sonic welding of fittings and other
agricultural products occurs principally at API's Ontario plant. All injection
molding and structural foam molding occurs at the Ny-Glass plant, which is ISO
9002 and UL certified, on molding machines ranging from 75 to 800 tons clamping
force.

     RAW MATERIALS; INVENTORIES.  Calnetics maintains an inventory of raw
materials and finished goods for sale at levels determined to be desirable to
enable each operating subsidiary to quickly respond to customer demand. Although
such raw materials and finished goods on hand represent a substantial commitment
of working capital, Calnetics believes that a rapid response to customer catalog
orders is essential and that its inventory practices are not unusual in the
industries in which it competes.

     The principal raw materials used by Calnetics with respect to the
manufacture of its products are resins for producing plastic parts. Each
operating subsidiary maintains what it considers to be a reasonable supply of
raw material resins, typically ranging from 30 to 60 days' supply. These amounts
are not increased except in times of expected shortages. Such resins are
purchased in pelletized form from several different suppliers, such as Dow
Chemical, Muehlstein, Cyro, Union Carbide, DuPont and GE Plastics. Calnetics is
not currently a party to any long-term agreements for the purchase of resins.
None of the operating subsidiaries is dependent upon any one supplier for its
present requirements of such resins nor are any such subsidiaries experiencing
any shortages in supply, although Manchester Plastics experienced nominal
shortages of polycarbonate resin in the 1996 fiscal year. However, there can be
no assurance that shortages in one or more types of resin will not occur from
time to time.

     CUSTOMERS AND MARKETING.  Calnetics' largest customer, which is a customer
of Ny-Glass, represented less than five percent of its combined net sales for
the last fiscal year. Although export sales of certain products are increasing,
such sales represented less than five percent of combined net sales for the last
fiscal year. API sells a large percentage of its products to customers in the
Central Valley of California. Although Calnetics previously believed that the
floods in such area earlier this calendar year would have an adverse impact on
sales of agricultural irrigation products, a reduction in sales did not
materialize. Calnetics does not have any government contracts or any other
contracts which are subject to the renegotiation of profits or termination at
the election of the government.

     Calnetics markets its products at all four facilities by use of in-house
sales personnel and a limited number of outside sales representatives and
independent manufacturers representatives.

     BACKLOG; SEASONALITY.  Backlog orders consist of written purchase orders
and telephone orders generally confirmed in writing or by substantially
concurrent delivery and acceptance of product. Calnetics estimates that
approximately 90% of its sales orders are written. Calnetics normally does not
offer cancellation rights and considers its backlog of orders to be firm. As of
June 30, 1997 and 1996, backlog for all products was approximately $2,497,000
and $2,508,000, respectively. The backlog as of the end of the fiscal year on
June 30, 1995 was $2,290,000. Typically, Calnetics anticipates that
approximately 95% of its backlog at any given time will be filled during the
subsequent 12 months.

     Prior to the 1995 fiscal year, Calnetic's business was not of a seasonal
nature, as neither the Manchester Plastics nor Ny-Glass subsidiaries experienced
seasonality in the sale of their products. However, the business of 

                                       9
<PAGE>
 
the API subsidiary, which was purchased effective two months prior to the 1995
fiscal year, has historically been seasonal in nature, with demand for its
irrigation products highest during the spring and early summer. In fiscal 1997,
the business of Calnetics reflected this trend, with approximately $17,032,000
of revenue in the first half of the fiscal year (July through December) and
approximately $19,584,000 during the remainder of the fiscal year (January
through June).

     COMPETITION.  Calnetics encounters extensive competition from many
competitors, a substantial number of which are larger and have greater financial
and marketing resources. In addition, Calnetics believes that the number of
international entities attempting to compete in its markets is increasing.
Although it is difficult to estimate the number of businesses in the plastic
manufacturing industry with which Calnetics competes, the injection molding
business operated by Ny-Glass appears to have the most competitors, ranging from
numerous small proprietorships to large corporations, while Manchester Plastics
competes principally with a lesser number of large corporations and API competes
principally with a lesser number of corporations of similar and larger size.

     Competition is based principally on price, product quality, customer
service and the ability to timely deliver products. Calnetics believes that each
operating subsidiary has good relationships with its customers, and that such
subsidiaries have developed a good following in the respective markets they
serve, including a favorable reputation for prompt and reliable customer service
and quality of products.

     PATENTS AND TRADEMARKS.  Although Calnetics has a limited number of
domestic patents and trademarks held by API as well as several trademark
applications currently in process, Calnetics does not believe that any such
patents or trademarks are material to its businesses or operations.

     RESEARCH AND DEVELOPMENT.  Calnetics has not expended a material amount on
research and development of proprietary products in the past several years and
currently does not anticipate any material expenditures in this area. However,
Calnetics does conduct routine product line analysis to develop additional
catalog and custom products as part of its normal operations, particularly at
API and, to a lesser extent, at Ny-Glass.

     LEGAL PROCEEDINGS. In the ordinary course of its business, Calnetics and/or
one or more of the operating subsidiaries may become involved in legal
proceedings from time to time. As of June 30, 1997, neither Calnetics nor any of
the operating subsidiaries is a party to any material pending legal proceedings.

     TAX EXAMINATION.  API is in the process of an Internal Revenue Service
("IRS") examination regarding the tax-exempt status of its industrial revenue
bond. The IRS has informed Calnetics that preliminary findings indicate that the
bond may not be tax exempt and thus API may be required to pay additional
interest. Calnetics believes it has recorded adequate reserves to cover any
potential liability that may result from the final resolution of this matter.

     ENVIRONMENTAL MATTERS.  Calnetics believes that its policy in controlling
the use and discharge of hazardous materials is in compliance with applicable
federal, state and local regulations. As of June 30, 1997, Calnetics had not
received notice from any governmental authority of any assertion of material 
non-compliance with any such laws.

     Calnetics formerly operated a facility on property within an area
subsequently designated as a federal Superfund site located in Southern
California. Calnetics operated at this facility prior to October 1986. Calnetics
has learned that hazardous substances have been identified in the subsurface of
the property and that the current owner has been requested by a state agency to
undertake additional investigation at the property. Calnetics is also 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.
Calnetics, as one of several prior operators of the property, may be held
responsible for the contamination at the site to the extent Calnetics caused the
contamination. Calnetics does not believe it is responsible for any material
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 Calnetics were held liable under federal Superfund
law, or other environmental law, the consequences 

                                       10
<PAGE>
 
could be material to the results of operations of Calnetics.

     EMPLOYEES.  At June 30, 1997, Calnetics employed approximately 262
employees, consisting of three employees at corporate headquarters,
approximately 12 salaried and 39 hourly employees at Manchester Plastics,
approximately nine salaried and 48 hourly employees at Ny-Glass and
approximately 25 salaried, 91 hourly and 35 temporary employees at API. None of
the foregoing employees is subject to a collective bargaining agreement.
Calnetics considers the relationship with its employees to be good, and has not
experienced any work stoppage from any labor dispute.

                                       11

ITEM 2.  PROPERTIES

       Summa's principal executive offices are located in approximately 300
square feet of leased office space in Torrance, California. Summa anticipates
continuing to lease comparable space with no difficulty.

       LexaLite's original plant, which has been expanded several times,
comprises 94,000 square feet of manufacturing and office space on 14 acres of
land on the shore of Lake Michigan in Charlevoix, Michigan. The Lighting
Scientific Center ("LSC") comprises 27,500 square feet of office and
manufacturing area on 11 acres of land in a business park in Charlevoix. This
facility was constructed with utilities in place so that it can be modularly
expanded as required. Recently, the Lighting Research Center ("LRC") was
combined with the LSC, and the former LRC facilities, comprising 14,700 square
feet of office, testing and light manufacturing area on three-quarters of an
acre of land in Charlevoix, Michigan, were leased to a third party. The
Tennessee plant comprises 55,000 square feet of office and manufacturing area on
24 acres of land in Dickson, Tennessee. All four facilities are owned by
LexaLite, all of which are pledged to secure debt. The LSC was built with the
proceeds of a Michigan Industrial Revenue Bond.

       In January 1996, KVP relocated to a larger leased facility in an
industrial park in Rancho Cordova, California, which contains 48,000 square foot
office and manufacturing space, to provide for expanding operations of its
material handling component business. The lease expires in February 2001.

       GST leases 28,000 square feet of office and manufacturing space in an
industrial park in Santa Ana, California. The lease expires in October 1998.

       Summa believes that in general all of the facilities currently used by
each operating subsidiary are adequate for present and foreseeable needs, and
that expiring leases can be renegotiated or alternate facilities can be leased
on favorable terms, as necessary.

       Summa also owns approximately 63,000 square feet of factory and office
space on approximately 3.4 acres in Fullerton, California, which it leases to
Morehouse-COWLES, Inc., a former subsidiary of Summa. The lease expires in July
2006. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations - Sale of Discontinued Operations."

       Set forth below is additional information concerning the properties of
Calnetics which has been derived from the Annual Report on Form 10-K for the
year ended June 30, 1997 filed by Calnetics under the Exchange Act:

       The Manchester Plastics plant is located in Chatsworth, California,
consisting of approximately 60,000 square feet of office and manufacturing space
under a lease that is scheduled to expire in December 1999.

       The Ny-Glass plant is located in Corona, California, in a building
consisting of approximately 30,000 square feet of office and manufacturing space
under a lease that is scheduled to expire in May 2002.

       The API California plant is located in Ontario, California, in a building
consisting of approximately 50,000 square feet of office and manufacturing space
owned by API, subject to repayment of industrial revenue bonds. API's Florida
plant is located in Winter Haven, Florida, in two buildings consisting of
approximately 28,000 square feet of office and manufacturing space owned by API,
subject to payment of existing mortgages.

       In addition to the foregoing properties, additional space has been leased
by Calnetics at three locations and is being used principally for the
warehousing and storage of inventory. The largest location consists of
approximately 15,000 square feet of space leased by API in Ontario, California.

ITEM 3.   LEGAL PROCEEDINGS

          Summa encounters lawsuits from time to time in the ordinary course of
its business, and at August 31, 1997, Summa's wholly-owned subsidiaries KVP and
the Stang division of GST were each a party to the civil lawsuits described
below. Although Summa has been able to obtain liability insurance coverage for
each of the past five years, such insurance may not be available in the future
at economically feasible premium rates. Additionally, some lawsuits filed
against Summa 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 current or future 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 financial
condition and prospects of Summa.

          Laitram, et al. v. KVP Systems, Inc. et al. was filed in the U.S.
          -------------------------------------------                      
District Court in Eastern Louisiana in September 1993. The plaintiffs claim KVP
has infringed upon two patents. The venue was changed to the Federal District
Court in Sacramento, California. KVP contended the claims were invalid and filed
certain counterclaims. On April 24, 1997, the District Court ruled that KVP's
products do not infringe plaintiff's patents and also dismissed the
counterclaims. On May 28, 1997, the plaintiff filed a notice of appeal of the
summary judgment decision with the United States Court of Appeals, and KVP filed
a notice of appeal on June 5, 1997. Both parties have submitted appeal briefs to
the Court of Appeals. Although Summa believes it has a reasonable expectation of
prevailing on appeal and, therefore, has not established a reserve, in the
absence of applicable insurance, the consequences of an adverse determination
would be borne by Summa.

          In Wright v. Stang, et al., a piece of pipe, to which a water cannon
          --------------------------                                          
manufactured by Stang was attached, broke, knocking a fireman down. Since Stang
did not make or supply the pipe which failed, the case was dismissed.
Subsequently, the dismissal was reversed on appeal. Summa has $2,000,000 in
product liability insurance applicable in this case.

          For a discussion of certain proceedings relating to Calnetics, see
"Business - Acquisition of Calnetics -Tax Examination;" and "- Environmental
Matters" in Item 1 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, 1997 to a vote of Summa's shareholders, through solicitation of
proxies or otherwise.

RECENT MARKET PRICES
- --------------------

         Summa's Common Stock is traded on The Nasdaq National Market under the
symbol "SUMX." Historically, there has been a limited public market for Summa's
Common Stock. During the year ended August 31, 1997, the average weekly trading
volume increased to approximately 26,000 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 closing prices for
a share of Summa's Common Stock on The Nasdaq National Market for the periods
indicated.

 </TABLE>

         On November 5, 1997, the closing price on The Nasdaq National Market
for a share of Summa Common Stock was $10.25.

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, 1997, 4,099,004 shares of Summa's Common Stock were
issued and outstanding, including a total of 2,721,728 shares held by non-
affiliates of Summa, and no shares of Preferred Stock had been issued or were
outstanding. The approximate number of holders of record of Summa's Common Stock
as of November 1, 1997, was 488. In addition, Summa estimates that there are
approximately 600 additional shareholders whose shares are held in "street
name."

         COMMON STOCK.  Holders of the Common Stock are entitled to one vote per
share on each matter submitted to a vote of the shareholders 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, the 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,
and its telephone number is: (818) 502-1404.

                                       14
<PAGE>
 
         PREFERRED STOCK.  The Board of Directors is authorized, subject to any
limitations prescribed by the laws of the State of California, but without
further action by Summa's shareholders, 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 shareholders.  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 Articles of Incorporation and Bylaws provide for elimination of
cumulative voting and the classification of the Board of Directors, provisions
which are also likely to delay, discourage or prevent a change in control of
Summa.

SHARES ISSUABLE UPON EXERCISE OF OPTIONS
- ----------------------------------------

         Summa has registered 837,517 shares issuable upon exercise of options
granted and available to be granted under its stock option plans and in
connection with acquisitions.  The existence of such stock options may adversely
affect the terms on which Summa can obtain additional financing, and the holders
of such options can be expected to exercise or convert such options 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.

DIVIDEND POLICY
- ---------------

       Summa has not paid a cash dividend since the fiscal year ended August 31,
1983.  Summa intends to retain earnings, if any, for use in its business and
currently does not 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 that 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. 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 in this Annual
Report on Form 10-K. The forward-looking statements are made as of the date
hereof, and Summa 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.

          As discussed in more detail under Item 1 above, Summa has adopted a
strategy of growth by acquisitions. Although GST and KVP had each been
established for over 15 years prior to their acquisition by Summa, such have
been operating under their current ownership structure for only six years and
four years, respectively. LexaLite, in turn, has operated as a wholly-owned
subsidiary of Summa only since November 22, 1996. There can be no assurance that
Summa will be able to sustain rates of revenue growth and profitability in
future periods which are comparable to those experienced in the past several
years.

          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 enhanced financial,
marketing and administrative support to be furnished by the executive officers
of Summa. 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
implement its acquisition strategy on terms and conditions that are acceptable
to Summa, if at all. See "- Acquisition of Calnetics" below in this Item 7.
      
          Summa's LexaLite subsidiary sells its products and services primarily
to manufacturers of lighting fixtures, of which there are a limited number. As a
consequence, a significant portion of LexaLite sales are to relatively few
customers. Most of the sales of aerospace assemblies by Summa's GST subsidiary
are for the F-16 and derivative aircraft, and are made to a foreign government
engaged in a U.S. sanctioned cooperative aircraft manufacturing program, to
Lockheed Aircraft, and to the Department of Defense. Because the F-16 is a
mature program which is being phased out, GST faces a possible loss of most of
its defense related business over the next several years. The sales of the
aerospace assemblies segment represented 15%, 15% and 4% of Summa's consolidated
net sales for fiscal years 1995, 1996 and 1997, respectively, with sales to the
largest aerospace customer for the fiscal years ended August 31, 1995, 1996 and
1997 constituting 7%, 6% and 2% of consolidated net sales, respectively. The
largest customer of any operating subsidiary during the fiscal years ended
August 31, 1995, 1996 and 1997 represented approximately 7%, 6% and 8% of
consolidated net sales, respectively. There can be no assurance that the loss of
more than one of these significant customers would not occur simultaneously.

          As of August 31, 1997, Summa's consolidated backlog had increased to
$6,323,000, as compared to consolidated backlog of $2,475,000 and $2,924,000 as
of August 31, 1996 and 1995, respectively. Summa's consolidated backlog for the
current fiscal year increased over last fiscal year's backlog primarily due to
the addition of backlog resulting

                                       17
<PAGE>
 
from the acquisition of LexaLite during fiscal 1997, partially offset by a
decrease in the backlog of the defense business. Fiscal 1996 backlog decreased
to $2,475,000 as compared to fiscal 1995 backlog of $2,924,000, primarily as a
result of decreased backlog in the defense business at such time. The open order
backlog, believed to be firm, is comprised of orders for components and spare
parts, with scheduled deliveries from September 1997 through fiscal 1999.
However, Summa faces a probable loss of most of its defense related business
over the next several years, as mature programs are wound down. Because Summa
has historically booked some disproportionately large orders during its fiscal
years, and because backlog is usually not material except in the defense
business, the amount of firm order backlog at year-end cannot necessarily be
used as an indicator of future sales volume.

          Although none of the businesses conducted by Summa's operating
subsidiaries as of August 31, 1997 is considered to be seasonal, each involves
the sale of components to be incorporated into capital equipment provided by its
customers, the demand for which depends upon a number of factors beyond the
control of Summa. Among other factors which would affect the demand for the
products offered by Summa, it can be expected that economic conditions
generally, the availability of credit, as well as industry conditions in the
markets for Summa's products, could have a significant impact upon the decisions
of prospective customers as to the timing of purchases of additional or
replacement products. For these and other reasons, it is possible that Summa's
quarterly revenues and profitability on a consolidated basis may fluctuate from
time to time, although the likelihood of extreme changes may be mitigated by the
fact that the operating subsidiaries sell components into several different
markets. Moreover, there can be no assurance that a major economic downturn or
severe tightening of credit would not adversely affect the demand for all of
Summa's products concurrently. For a discussion regarding the seasonal nature of
the business of Calnetics' API subsidiary, see Item 1 "Business - Acquisition of
Calnetics - Backlog; Seasonality" above.

          Any future success that Summa might enjoy will depend upon many
factors including factors which may be beyond the control of Summa or which
cannot be predicted at this time. These factors may include changes in the
markets for the products offered by Summa through its operating subsidiaries,
increased levels of competition including the entry of additional competitors
and increased success by existing competitors, reduced margins caused by
competitive pressures and other factors, increases in operating costs including
costs of production, supplies, personnel, equipment, import duties and
transportation, increases in governmental regulation imposed under federal,
state or local laws, including regulations applicable to environmental, labor
and trade matters, changing customer profiles and general economic and industry
conditions that affect customer demand, the introduction of new products by the
Summa or its competitors, the timing of the Summa's advertising and promotional
campaigns, and other factors.

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

  RESULTS OF OPERATIONS
  ---------------------

          The following table sets forth certain information derived from
Summa's consolidated statements of income for continuing operations as a
percentage of sales for the three years ended August 31, 1995, 1996 and 1997, as
well as Summa's effective income tax rate for each period presented. As
discussed in more detail below, Summa's statements of income have been restated
to reflect the discontinuance of operations and subsequent sale in 1996 of the
Morehouse-COWLES industrial process equipment business.

 </TABLE>

          NET SALES. For the year ended August 31, 1996, net sales increased by
$2,495,000, or 24%, over the prior fiscal year, primarily due to continued
growth in sales in the material handling components business and increased sales
by Stang as a result of participation in increased building and expansion
activity in the petrochemical industry.

          For the year ended August 31, 1997, net sales increased by
$30,495,000, or 239%, over the prior fiscal year, primarily due to the inclusion
of nine months of sales for the newly acquired plastic optical components
business of LexaLite and strong continued growth in the sales of the material
handling components business. KVP's sales growth is attributable to growing
acceptance of its products, the market for its products and use of an expanded
sales force.
 
          GROSS PROFIT. Gross profit for the year ended August 31, 1996 was
$5,895,000, an increase of $1,257,000, or 27%, over the level of gross profit
generated during the year ended August 31, 1995. The increase in gross profit is
primarily due to the growth in the material handling components business and
increased sales by Stang. As a percentage of sales, the gross profit margin
increased from 45.3% for the year ended August 31, 1995 to 46.3% for the year
ended August 31, 1996, primarily due to improved margins at Stang related to
higher volume.
 
          Gross profit for the year ended August 31, 1997 increased by
$8,027,000 to $13,922,000, an increase of 136% over the level of gross profit
generated during the prior fiscal year. The increase in gross profit is
primarily due to the inclusion of nine months of operations of the newly
acquired plastic optical components business of LexaLite and growth in the
material handling components business. As a percentage of sales, the gross
profit margin decreased from 46.3% for the year ended August 31, 1996 to 32.2%
for the year ended August 31, 1997, primarily due to the inclusion of sales of
the plastic optical components business at typically lower margins than those of
Summa's other businesses. Gross margin percentages of Summa's other businesses
increased slightly, due primarily to price increases and increased volume.
 
          SELLING, GENERAL AND ADMINISTRATIVE EXPENSE. Selling, general and
administrative expenses for the year ended August 31, 1996 increased by
$1,051,000, or 30%, when compared to total operating expenses for fiscal year
1995, and as a percentage of sales, increased from 34.0% to 35.6%, largely
reflecting increases in sales and marketing expenses at KVP associated with
expanding the sales organization and due to increased contingent performance
payments related to increased sales and profitability at GST and Stang.
 

                                       19
<PAGE>
 
          For the year ended August 31, 1997, selling, general and
administrative expenses increased by $5,090,000, or 112%, when compared to total
operating expenses for the prior fiscal year, primarily due to the inclusion of
nine months of expenses of the newly acquired plastic optical components
business of LexaLite and growth in the material handling components business. As
a percentage of sales, selling, general and administrative expenses decreased
from 35.6% to 22.3%, due mostly to the inclusion of the plastic optical
components business which operates with lower operating expenses as a percentage
of sales.

          OTHER EXPENSE. Other expense increased from minor amounts for the
fiscal years ended August 31, 1995 and 1996 to $254,000 in the fiscal year ended
August 31, 1997, due primarily to costs incurred in the first attempted
acquisition of Calnetics which was aborted on May 7, 1997. See Note 17 in the
"Notes to Consolidated Financial Statements" of Summa in this Annual Report on
Form 10-K for a description of the subsequent successful acquisition of 
Calnetics.

          INTEREST. Interest income increased from minor amounts for the fiscal
years ended August 31, 1995 and 1996 to $200,000 in the fiscal year ended August
31, 1997, due primarily to interest earned on the note receivable which was
received as partial consideration for the sale of Morehouse-COWLES, Inc. in May
1996, interest earned on funds held in trust which were acquired with the
acquisition of LexaLite, and interest earned on funds set aside for the payment
of industrial revenue bonds. Interest expense increased from minor amounts for
the fiscal years ended August 31, 1995 and 1996 to $475,000 in the fiscal year
ended August 31, 1997, due primarily to interest on debt acquired in the
acquisition of LexaLite.

          EFFECTIVE TAX RATE. The effective income tax rate, which is a
composite of federal and state taxes, decreased from 41.6% for fiscal 1995 to
40.3% in fiscal 1996, primarily because there were no non-deductible contingent
performance accruals due the former shareholders of GST in fiscal 1996 as were
due in fiscal 1995. In fiscal 1997, the effective tax rate decreased slightly to
40.2% from 40.3% in fiscal 1996.

          BACKLOG. Backlog increased slightly during fiscal 1995 to $2,924,000
at August 31, 1995. By August 31, 1996, backlog had decreased to $2,475,000, as
a result of decreased backlog in the defense business. At August 31, 1997,
backlog increased to $6,323,000, primarily due to the addition of backlog for
tooling and products relating to the plastic optical components business of
LexaLite, amounts not included in the fiscal 1996 consolidated backlog total as
LexaLite was acquired after the fiscal 1996 year end, partially offset by a
continued decrease in the backlog of the defense business. The open order
backlog, believed to be firm, is comprised of orders for components and spare
parts, with scheduled deliveries from September 1997 through fiscal 1999.
However, Summa faces a probable loss of most of its defense related business
over the next several years, as mature programs are wound down. Because Summa
has historically booked some disproportionately large orders during its fiscal
years, and because backlog is usually not material except in the defense
business, the amount of firm order backlog at year-end cannot necessarily be
used as an indicator of future sales volume.
 
          INFLATION. Although the impact of inflation is difficult to accurately
assess, management of Summa does not believe that inflation has had a
significant impact on Summa's net sales and revenues, or on income from
continuing operations in the current fiscal year or in the two preceding fiscal
years.

  LIQUIDITY AND CAPITAL RESOURCES
  -------------------------------

          Cash provided by operating activities is Summa's most important source
of liquidity. During the fiscal year ended August 31, 1995, Summa used $235,000
of cash, primarily because cash used by discontinued operations of $894,000
related to inventory growth more than offset cash provided by continuing
operations of $659,000. Net cash provided by operating activities for the fiscal
year ended August 31, 1996 was $1,577,000, substantially from continuing
operations. Net cash provided by operating activities for the fiscal year ended
August 31, 1997 was $3,597,000, primarily due to the inclusion of LexaLite
offset by cash used in payment of the final contingent performance accruals. The
improved cash flows for the two most recent fiscal years are primarily
attributable to the inclusion of LexaLite, lower payments of accrued 

                                       20
<PAGE>
 
contingent performance payments and lower required tax payments.
         
          During the fiscal year ended August 31, 1996, working capital of
Summa's continuing operations increased by $1,093,000, or 58%, from $1,882,000
at August 31, 1995 to $2,975,000 at August 31, 1996, reflecting decreased
utilization of the line of credit. As of August 31, 1997, Summa's working
capital had increased to $8,104,000, due primarily to the inclusion of LexaLite
and to decreased accrued contingent performance payments.

          Asset utilization for the fiscal years ended August 31, 1995, 1996 and
1997 is illustrated in the following table:

</TABLE>

          The investment in property, plant and equipment in the years ended
August 31, 1995 and 1996 relates primarily to the acquisition of molds for new
products in the material handling components business. For the year ended August
31, 1997, such investment relates primarily to purchases of injection molding
equipment and completion of the LexaLite Scientific Center for the optical
components business as well as the acquisition of molds for new products. Summa
expects to continue to invest heavily in tooling for new products .

          At August 31, 1997, Summa was not committed to any outside supplier
for major capital expenditures, and it believes its present capacity, augmented
by anticipated continued investment in new product tooling for the materials
handling components business and the plastic optical components business and in
injection molding equipment for the optical components business, will be
sufficient to meet demand for its products with a competitive lead time and to
produce quality products in a cost-effective manner. Summa believes that cash
flows from operations will be sufficient to fund working capital and planned
capital expenditure requirements for the next twelve months.

          At August 31, 1997, Summa had various working capital and equipment
acquisition credit facilities with two banks, aggregating $7,000,000, of which
none was in use. Both of the working capital lines of credit bore interest at
their respective banks' prime rate (8.5% at August 31, 1997). Subsequent to
fiscal year end, these credit facilities were terminated and replaced by the
financing discussed below.

          In connection with the financing of the Calnetics acquisition, Summa
entered into new credit facilities consisting of $13,500,000 in term debt, a
three year revolving line of credit of up to $15,000,000 depending upon the
amount of eligible accounts receivable and inventory, and a $5,000,000 facility
available for three years to acquire equipment which would be repayable in
monthly installments over seven years. The Company anticipates that the entire
$13,500,000 term debt and approximately $9,500,000 of the revolving line of
credit will be used in connection with the Calnetics acquisition. The term debt
requires monthly principal payments of $83,333 in the first year, $166,667 in
years two through six and $208,333 in year seven. Interest is due monthly on
both facilities at a base rate plus an applicable margin. At October 31, 1997,
based upon the base rate optionally selected, most of Summa's debt incurred in
connection with the acquisition of Calnetics bears interest at below the prime
rate.

          Substantially all of Summa's assets, and the assets of newly acquired
Calnetics, not pledged to secure other financing, are pledged to secure the term
debt and revolving bank line of credit described above. The term debt and
revolving line of credit require compliance with various bank convenants.

          Summa believes that cash flows from operations and existing credit
facilities will be sufficient to fund planned capital expenditure and working
capital requirements for the next twelve months.

ACQUISITION OF CALNETICS
- ------------------------

          On October 28, 1997, Summa acquired all of the outstanding capital
stock of Calnetics through a merger of a newly formed and wholly-owned
subsidiary of Summa with and into Calnetics in which the former shareholders of
Calnetics received an aggregate of approximately $22,335,000 in cash and Summa
assumed approximately $1.8 million in indebtedness.

          It is anticipated that each of the three operating subsidiaries of
Calnetics will continue to operate on a semi-autonomous basis in much the same
way as the three operating subsidiaries of Summa currently function. The
management of each operating subsidiary has independent profit and loss
responsibility, subject to the achievement of specified objectives and
compliance with budgetary goals set forth in an operating plan developed each
year in consultation with Mr. Swartwout, the Chief Executive Officer of Summa,
and presented to the Summa Board of Directors for approval on an annual basis.

          Summa has no employees other than Mr. Swartwout, Paul A. Walbrun, its
Controller, and an administrative assistant. Trygve M. Thoresen, formerly a Vice
President and the General Counsel of Calnetics, joined Summa in a comparable
capacity at the time of the Calnetics acquisition. The corporate staff does not
direct operations of subsidiaries on an ongoing basis but, in addition to
planning and financial oversight, provides financing, conducts Summa's
acquisition program and business development activities, and handles legal and
investor relations matters. In addition, from time to time the corporate staff
is active in non-operational business activities, such as risk management and
employee benefit program management. Summa assesses corporate charges on a basis
established annually, related to asset utilization by subsidiaries.

          The Calnetics acquisition will be accounted for as a purchase by Summa
of the net assets of Calnetics. The following table summarizes (in thousands)
information set forth in the audited financial statements of Calnetics and the
notes thereto which are included under Item 14(a) of this Annual Report on Form
10-K, and should be read in conjunction with those financial statements and the
related notes.

SALE OF DISCONTINUED OPERATIONS
- -------------------------------

          On June 17, 1996, Summa completed the sale of all of the issued and
outstanding capital stock of Morehouse-COWLES, Inc. to a private investment
group based in Michigan. In exchange for all of the capital stock of Morehouse-
COWLES, Inc., Summa was paid $750,000 in cash and will be paid an additional
$1,771,000 on the terms and conditions set forth in a subordinated promissory
note. The subordinated note provides for the payment of interest monthly at the
rate of 7% per annum through June 2001, and at the rate of 9% per annum through
June 2006, and provides for monthly principal payments commencing July 2001
utilizing a 10-year amortization schedule with all unpaid interest and principal
due and payable by June 30, 2006. The note is subordinated to the investor's
bank credit agreement, permits optional prepayments, contains certain covenants
and default provisions and remedies, and is secured by a pledge of all of the
outstanding capital stock of Morehouse-COWLES, Inc. Additionally, the investment
group entered into a new lease with the wholly-owned subsidiary of Summa that
holds title to Summa's Fullerton facilities, in which the operations of
Morehouse-COWLES also have been conducted. The lease is for a period of ten
years, with an option to extend the term of the lease for an additional five
years. The monthly rent, on a "triple-net basis," is $4,000 during the first
five years of the lease, increasing to $5,500 per month during the second five
years of the original lease term.

          On January 30, 1996, Summa had previously announced that it had
entered into a letter of intent to sell Morehouse-COWLES to another prospective
purchaser. Accordingly, Morehouse-COWLES, Inc. has been treated for accounting
purposes as a discontinued operation in the interim financial statements of
Summa published since that date. For the nine months ended May 31, 1996,
Morehouse-COWLES, Inc. lost $421,000 before income taxes, on sales of
$5,638,000, compared to net income of $7,000 before taxes on sales of $6,048,000
for the nine months ended May 31, 1995.

RECENT ACCOUNTING PRONOUNCEMENTS
- --------------------------------
 
          Summa has elected to continue to report stock based compensation in
accordance with Accounting Principles Board Opinion No. 25, "Accounting for
Stock issued to Employees." Summa has adopted the appropriate disclosure
requirements of Statement of Financial Accounting Standards (SFAS) No. 123,
"Accounting for Stock-Based Compensation."

          In February 1997, the Financial Accounting Standards Board (FASB)
issued SFAS No. 128 ,"Earnings Per Share," which establishes new standards for
computing and presenting earnings per share. This statement will be adopted by
Summa for the 1998 fiscal year. Summa does not believe that adoption of the
pronouncement will have a material effect on reported earnings per share.

          In February 1997, the FASB issued SFAS No. 129, "Disclosure of
Information about Capital Structure," which establishes standards for disclosing
information about an entity's capital structure. This statement will be adopted
by Summa for the 1998 fiscal year. Based on the capital structure disclosures
presented in the accompanying consolidated financial statements and notes
thereto, the Company does not believe that any additional disclosures will be
required as a result of adopting this pronouncement.

          In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which establishes standards for reporting and display of comprehensive
income and its components. This statement will be adopted by Summa for the 1999
fiscal year. The Company does not believe that the adoption of this
pronouncement will have a material effect on reported income.

          In June 1997, the FASB issued SFAS No. 131, "Disclosures About
Segments of an Enterprise and Related Information," which establishes standards
for reporting and disclosure of financial information by segment. This statement
will be adopted by Summa for the 1999 fiscal year. The effect of adoption of
this pronouncement has not yet been determined.

Report of Independent Public Accountants

TO:    THE BOARD OF DIRECTORS AND SHAREHOLDERS OF SUMMA INDUSTRIES

We have audited the accompanying consolidated balance sheets of SUMMA INDUSTRIES
(a California corporation) and subsidiaries as of August 31, 1996 and 1997 and
the related consolidated statements of income, shareholders' equity and cash
flows for each of the three years in the period ended August 31, 1997. 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 generally accepted auditing
standards.  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, 1996 and 1997, and the results of their operations
and their cash flows for each of the three years in the period ended August 31,
1997, in conformity with generally accepted accounting principles.

SUMMA INDUSTRIES
Notes to Consolidated Financial Statements

For the years ended August 31, 1995, 1996 and 1997.

1.   DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

SUMMA INDUSTRIES ("SUMMA"), which was incorporated in California in 1942,
currently serves as a holding company whose businesses are conducted
primarily through its three wholly-owned subsidiaries, LexaLite
International Corporation, KVP Systems, Inc. and GST Industries, Inc.
SUMMA's subsidiaries manufacture proprietary industrial components.
Products include engineered injection-molded plastic optical components for
OEM customers in the lighting industry, conveyor components for food
manufacturing industries, aerospace actuators and firefighting components
for petrochemical plants.  Sales are domestic and worldwide (see Note 12).

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of SUMMA
INDUSTRIES and its wholly-owned subsidiaries. The  results of operations of
LexaLite have been included in the consolidated results of operations and
the consolidated statement of cash flows of the Company  and the shares
issued to complete the acquisition have been included in the earnings per
share calculation since November 22, 1996.  The acquisition of LexaLite is
more fully described in Note 16.  The consolidated financial statements
also include the discontinued operations of Morehouse-COWLES, Inc.
("Morehouse-COWLES"), in 1995 and 1996.  All intercompany account balances
and transactions have been eliminated in consolidation.  Certain
reclassifications of 1995 and 1996 amounts have been made to conform to
1997 presentations.

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

The preparation of financial statements in conformity with 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 on 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:

     Building and improvements          10-20 years
     Machinery and equipment            3-15 years
     Office furniture and equipment     3-10 years
     Leasehold improvements             Lesser of remaining term of lease or
                                        estimated useful life

Maintenance, repairs and minor renewals are charged directly to expense as
incurred. Additions and betterments 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.

                                      F-7
<PAGE>
 
INTANGIBLE ASSETS

Intangible assets primarily include goodwill and other intangibles such as trade
names, patents and customer relationships capitalized in connection with
business acquisitions. Other intangibles are being amortized over their
estimated useful lives of 10-17 years. Goodwill is amortized over 25 years (see
Note 6).

NET INCOME PER COMMON AND EQUIVALENT SHARE

Per share amounts are based on the weighted average number of common and
equivalent shares outstanding during each year. Common equivalent shares relate
to shares issuable upon the exercise of stock options (Note 11). Income per
common and equivalent share is the same as fully diluted earnings per share for
all years presented. Weighted average common and equivalent shares outstanding
were 1,553,000 for 1995, 1,603,000 for 1996 and 3,521,000 for 1997.

STATEMENTS OF CASH FLOWS

For purposes of the statements of cash flows, the Company considers all highly
liquid debt instruments with a maturity of three months or less to be cash
equivalents.

INCOME TAXES

The Company accounts for income taxes in accordance with the Statement of
Financial Accounting Standards (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 in
accordance with Accounting Principles Board Opinion No. 25, "Accounting for
Stock issued to Employees." The Company has adopted the appropriate disclosure
requirements of Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation" (see Note 11).

PENDING ACCOUNTING PRONOUNCEMENTS

In February 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 128 "Earnings Per Share,"
which establishes new standards for computing and presenting earnings per share.
This statement will be adopted by the Company for the 1998 fiscal year. The
Company does not believe that the adoption of this pronouncement will have a
material effect on reported earnings per share.

In February 1997, the FASB issued SFAS No. 129 "Disclosure of Information about
Capital Structure," which establishes standards for disclosing information about
an entity's capital structure. This statement will be adopted by the Company for
the 1998 fiscal year. Based on the capital structure disclosures presented in
the accompanying consolidated financial statements and notes thereto, the
Company does not believe that any additional disclosures will be required as a
result of adopting this pronouncement.

In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income,"
which establishes standards for reporting and display of comprehensive income
and its components. This statement will be adopted by the Company for the 1999
fiscal year. The Company does not believe that the adoption of this
pronouncement will have a material effect on reported income.

In June 1997, the FASB issued SFAS No. 131, "Disclosures About Segments of an
Enterprise and Related Information," which establishes standards for reporting
and disclosure of financial information by segment. This statement will be
adopted by the Company for the 1999 fiscal year. The effect of adoption of this
pronouncement has not yet been determined.

                                      F-8

2.   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 - The carrying amount is a reasonable estimate of
     fair value. These assets consist of short term certificates of deposit and
     demand deposits.

     NOTE RECEIVABLE - The note receivable was received as partial consideration
     for the sale of all of the stock of Morehouse-COWLES. The carrying value is
     not materially different than the fair value. (See Note 5.)

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

3.   INVENTORIES

Inventories consist of the following:

4.   PROPERTY AND EQUIPMENT LEASED TO OTHERS AND RENTAL INCOME

Included in property, plant and equipment are certain land and buildings which
are being leased to Morehouse-COWLES. The cost of the land is $550,000 and the
cost of the building is $1,208,000 less accumulated depreciation of $973,000 at
August 31, 1997. The lease expires in 2006 with an option for an additional five
years. The monthly rent, on a "triple-net basis" is $4,000 through June 2001,
increasing to $5,500 per month from June 2001 through June 2006. For the years
ended August 31, 1996 and August 31, 1997, depreciation expense was $17,000 and
$57,000, respectively and rental income was $8,000 and $48,000, respectively.

5.   OTHER ASSETS

Other assets consist primarily of a note receivable for $1,771,000 received as
partial consideration for the sale of all of the stock of Morehouse-COWLES. The
note is subordinated to the buyers' bank credit agreement and is secured by a
pledge of all of the outstanding capital stock of Morehouse-COWLES as well as by
the assets of Morehouse-COWLES. Under the terms of the note, interest is due
monthly at an annual rate of 7 percent until June 2001. Interest at 9 percent
and amortizing principal payments will be due monthly from June 2001 through
June 2006. At August 31, 1997, other assets also include bond proceeds held in
trust of $371,000.

Included in long term debt is $200,000 borrowed from an officer of a subsidiary.
Interest paid to the officer, at a market rate was $32,000 in 1995, $33,000 in
1996 and $26,000 in 1997.

Future maturities long term at August 31, 1997 are as follows:

At August 31, 1997, the Company had various working capital and equipment
acquisition credit facilities, with two banks, aggregating $7,000,000, of which
none was in use. Both of the working capital lines of credit bear interest at
their respective banks' prime rate (8.5 percent at August 31, 1997).
Substantially all of the Company's assets are pledged to secure the outstanding
debt and credit facilities. The working capital lines of credit require
compliance with various bank covenants. The credit facilities in place at August
31, 1997 have been replaced by new facilities in connection with the financing
for the acquisition of Calnetics Corporation, ("Calnetics") which is more fully
described in Note 17.

9.   COMMITMENTS AND CONTINGENCIES

The Company is a party to a civil lawsuit in which the plaintiffs have alleged
patent infringement. The Company contends the claims are invalid, and the court
dismissed the claims. Plaintiff has appealed the dismissal. Since the case
involves a number of complex factual and legal issues, it is impossible to
predict the outcome or estimate the loss, if any. The Company believes it has a
reasonable expectation of prevailing and therefore has not recorded any reserve
in connection with this matter. Consequently any adverse determination could
have a material effect on the Company's financial statements.
                                                                                
The Company is involved in a product liability case which was dismissed. The
dismissal was appealed by the plaintiff. The Company believes it has adequate
product liability insurance in the event of an adverse outcome.

                                      F-11

The Company leases office and manufacturing facilities and certain equipment
under noncancelable operating leases which expire at various dates through June
2001. Rental expense charged to operations was approximately $266,000, $308,000
and $508,000 for the years ended August 31, 1995, 1996 and 1997, respectively.

The aggregate minimum future lease payments under these leases at August 31,
1996 are approximately as follows:

</TABLE>

401(K) PLAN

The Company has employee savings and investment plans covering substantially all
of its employees. The plans, which qualify under Section 401(k) of the Internal
Revenue Code, allow employees to defer specified percentages of their
compensation, as defined, in a tax-exempt trust. The Company is required to make
matching contributions at the discretion of the Board of Directors. The cost of
the Company matching contribution is partially offset by a reduction in payroll
taxes. Company contributions to the plan totaled $81,000 in 1995, $83,000 in
1996 and $357,000 in 1997.

10.  RELATED PARTY TRANSACTION

The Company paid commissions in the amount of $120,000 and consulting fees of
$28,000 to a company controlled by a director of the Company in accordance with
a design and consulting agreement entered into in 1993 by LexaLite, which was
acquired by the Company in fiscal 1997. In addition, the Company paid a one time
payment of $365,000 in consideration of amending the terms of the earlier
agreement by which LexaLite will continue to receive consulting services for
$30,000 per year and pay commissions of 0.75% (a reduction from the previously
existing rate) of sales of certain products up to the earlier to occur of the
cumulative commission payment of $650,000 or expiration of 12 years.

The Company paid $101,000 during 1997 for cleaning services to a company which
had a relationship by marriage to a former officer of one of the Company's
subsidiaries. The agreement which was competitively bid annually was not re-
awarded to the related party upon termination of the existing agreement.

The Company leases truck trailers from a company owned by an employee of the
Company under which the Company paid $25,000 in fiscal 1997 and under which the
Company is obligated to pay approximately $2,000 per month through June 2001.
Additionally, the Company paid that party $379,000 for trucking services under
an agreement which is renewable annually.

11.  STOCK-BASED COMPENSATION PLANS

The Company has three stock option plans, all of which have been approved by the
shareholders and are administered by its Board of Directors. The 1984 Stock
Option Plan (the "1984 Plan") provides for the grant of options to key employees
to purchase an aggregate of 25,000 shares of Common Stock. Under the 1991 Stock
Option Plan (the "1991 Plan"), options to purchase an aggregate of 150,000
shares of Common Stock may be granted to key employees, directors, consultants,
vendors and others. The 1995 Stock Option Plan (the "1995 Plan") provides for
the grant of options to purchase an aggregate of 250,000 shares of Common Stock,
which may be granted to key employees, directors, consultants, vendors,
customers and others. In connection with the acquisition of LexaLite in November
1996, the existing outstanding LexaLite options acquired were reissued into
stock options of the Company.

The Company accounts for stock options under APB Opinion No. 25. Under these
plans no compensation cost was recognized in fiscal 1995, 1996 and 1997,
respectfully. FASB Statement No. 123 "Accounting for Stock-Based Compensation"
was issued by the FASB in 1995 and, if fully adopted, changes the methods for
recognition of cost on plans similar to those of the Company. Adoption of FASB
Statement No. 123 is optional, however proforma

                                      F-12
<PAGE>
 
disclosures as if the Company had adopted the cost recognition method are
required. Had compensation cost for stock options awarded under these plans been
determined consistent with FASB Statement No. 123, the Company's net income and
earnings per share would have reflected the following pro-forma amounts:

</TABLE>

The Company has granted options of 433,123 shares under the above plans. Under
these Plans, the options are generally issued at fair market value at the grant
date. Options become vested 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 five or ten years from date of grant.
Options that are forfeited are again available for grant under the Plans.

A summary of the status of the Company's stock option plans at August 31, 1995,
August 31, 1996 and August 31, 1997 and changes during the years then ended is

</TABLE>

* During fiscal 1997 the Company granted 157,650 options under shareholder
approved Plans and issued 169,912 options in conjunction with the acquisition of
LexaLite.

Of the total options outstanding at August 31, 1997, 210,455 have exercises
prices of $2.72 to $4.99 with a weighted average exercise price of $3.998 and a
weighted average remaining contractual life of 6.75 years; 182,717 of these
options are exercisable at year end. The remaining 235,418 options outstanding
at August 31, 1997 have exercise prices of $5.00 to $6.00 with a weighted
average exercise price of $5.527 and a weighted average remaining contractual
life of 7.59 years; 53,532 of these options are exercisable at year end.

The fair value of each option grant is estimated on the date of grant using the
Black Scholes pricing model with the following assumptions used for grants in
fiscal years 1996 and 1997; weighted average risk-free interest rate of 5.74
percent and 6.24 percent, respectively; volatility of 30 percent and 35 percent,
respectively; expected dividend yields of 0.00 percent; and a weighted average
contractual life of 7.74 and 8.87 years, respectively.

15.  DISCONTINUED OPERATIONS

On June 17, 1996, the Company completed the divestiture of its industrial
process equipment subsidiary, Morehouse-COWLES, Inc. Accordingly, this business
unit has been accounted for as a discontinued operation and results of its
operations are segregated in the accompanying consolidated statements of income.
There was no gain or loss on the disposition of Morehouse-COWLES. Interest
expense of $87,000 and $93,000 was related to discontinued operations and
accordingly was allocated to discontinued operations for fiscal years 1995 and
1996, respectively. 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.

The sales from these discontinued operations were $8,097,000 and $5,638,000 for
the years ended August 31, 1995 and 1996, respectively.

16.  ACQUISITION

On November 22, 1996, the Company completed the acquisition of LexaLite
International Corporation. The total acquisition cost was $23,943,000,
consisting of 2,415,106 shares of SUMMA Common Stock issued to LexaLite
shareholders and 30,000 shares issued to a broker valued at an estimated market
value of $9,842,000, acquisition costs of $315,000 and liabilities associated or
incurred of $13,906,000. 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 the
liabilities assumed or incurred based upon their fair values at the date of
acquisition. The excess of purchase price over the fair values of the net assets
acquired amounted to $905,000 and has been recorded as goodwill which is being
amortized on a straight-line basis over 25 years.

The following information is presented as if the acquisition of LexaLite had
been made as of September 1, 1996 and September 1, 1995, respectively, with pro-
forma adjustments to give effect to the amortization of goodwill and other
intangibles, adjustments in depreciation and inventory value, the related income
tax effects, and the effect upon earnings per share of the additional shares of
stock given in exchange for LexaLite stock.

17.  SUBSEQUENT ACQUISITION (UNAUDITED)

On October 28, 1997, the Company completed the acquisition of Calnetics
Corporation ("Calnetics"). The total acquisition cost was $33,235,000,
consisting of cash of $22,335,000, acquisition costs estimated to be $80,000,
liabilities assumed or incurred of $9,425,000 and an assigned value of
$1,345,000 for options issued in conjunction with the transaction, primarily
replacement options issued to Calnetics employees who will continue with the
Company. The Company entered into a new banking facility to provide most of the
cash used to acquire the Calnetics stock. (See unaudited proforma financial
information included in the Company's 1997 Form 10K).

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
- ----------------------------------------


To the Directors and Shareholders of Calnetics Corporation:

We have audited the accompanying consolidated balance sheets of CALNETICS
CORPORATION (a California Corporation) and subsidiaries as of June 30, 1997 and
1996, and the related consolidated statements of income, shareholders' equity
and cash flows for each of the three years in the period ended June 30, 1997.
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 generally accepted auditing
standards. 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 Calnetics Corporation and
subsidiaries as of June 30, 1997 and 1996, and the results of their operations
and their cash flows for each of the three years in the period ended June 30,
1997, in conformity with generally accepted accounting principles.

1.   Basis of Presentation
     ---------------------

Calnetics Corporation (the Company) is engaged in manufacturing operations
through three wholly owned subsidiaries:

Manchester Plastics, Co., Inc. (Manchester), located in Chatsworth, California,
primarily manufactures proprietary products consisting of acrylic, polycarbonate
and polystyrene plastic sheets for the building material and industrial plastics
industries.

Ny-Glass Plastics, Inc. (Ny-Glass), located in Corona, California, manufactures
custom plastic injection molding components for original equipment manufacturers
and high-quality, close-tolerance molded plastic components for a wide variety
of industries. Approximately one-fifth of its production is proprietary,
consisting of products for the electronic, computer, automotive and other high-
tech industries.

Agricultural Products, Inc. (API), located in Ontario, California and Winter
Haven, Florida, manufactures and distributes various irrigation hoses, fittings
and other products primarily for the agriculture industry.

2.   Summary of Significant Accounting Policies
     ------------------------------------------

     Use of Estimates
     ----------------

     The preparation of financial statements in conformity with 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 revenue and expenses
     during the reporting period. Actual results could differ from those
     estimates.

     Principles of Consolidation
     ---------------------------

     The consolidated financial statements include the accounts of the Company
     and its three wholly owned subsidiaries. All significant intercompany
     transactions and accounts have been eliminated.

     Credit Risk
     -----------

     The Company's accounts receivable are unsecured and the Company is at risk
     to the extent such amounts become uncollectible. Customers are located
     primarily throughout the United States.

     Revenue Recognition
     -------------------

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

                                      F-24
<PAGE>
 
     Inventories
     -----------

     Inventories include costs of materials, labor and manufacturing overhead,
     and are stated at the lower of cost or market using the first-in, first-out
     (FIFO) and the last-in, first-out (LIFO) methods. The LIFO method is used
     for the finished goods inventory at Manchester and totals approximately
     $1,165,000. Inventories consist of the following:

            <S>               <C>         <C>
 
            Raw materials     $2,688,014  $2,661,261
            Finished goods     2,703,645   2,809,449
                              ----------  ----------
                              $5,391,659  $5,470,710
                              ==========  ==========
</TABLE>

     At June 30, 1997 and 1996, if the FIFO method had been used to value
     Manchester finished goods inventories, the stated value of inventories
     would have been higher by approximately $129,000 and $421,000,
     respectively. Income before provision for income taxes would have decreased
     by $292,000, increased by $13,000 and increased by $408,000 for 1997, 1996
     and 1995, respectively. Net income would have decreased by $175,000,
     increased by $7,000 and increased by $230,000 for 1997, 1996 and 1995,
     respectively.

     Property, Plant and Equipment
     -----------------------------

     Property, plant and equipment are stated at cost. The Company follows the
     policy of capitalizing expenditures that materially increase asset lives
     and charging ordinary maintenance and repairs to operations as incurred.
     Amounts expensed as maintenance and repairs were approximately $423,000,
     $336,000 and $370,000 in 1997, 1996 and 1995, respectively.

     When assets are sold or disposed of, the cost and related depreciation are
     removed from the accounts and any resulting gain or loss is included in
     income.

     Property, plant and equipment are depreciated and amortized using the
     straight-line and accelerated methods over the following useful lives:

            Buildings and improvements          7 - 31.5 years
            Leasehold improvements              term of lease
            Machinery and equipment             3 - 7 years
            Furniture and fixtures              5 - 7 years

     Goodwill
     --------

     Goodwill resulted from the purchase of Manchester during 1989 and the
     purchase of API in 1994. It is being amortized on a straight-line basis
     over 30 years and 20 years, respectively.

                                      F-25

     Statements of Cash Flows
     ------------------------

     For the purposes of the statements of cash flows, the Company considers all
     highly liquid investments with an original maturity date of 90 days or less
     to be cash and cash equivalents.

     Cash paid for income taxes was approximately $1,378,000, $1,041,000 and
     $932,000 in 1997, 1996 and 1995, respectively. Cash paid for interest was
     approximately $340,000, $445,000 and $511,000 in 1997, 1996 and 1995,
     respectively.

     Earnings Per Common Share
     -------------------------

     Earnings per common share and common share equivalent are based on the
     weighted average number of shares of common stock and common stock
     equivalents (dilutive stock options) outstanding during the related
     periods. The weighted average number of common stock equivalent shares
     includes shares issuable upon the assumed exercise of stock options, less
     the number of shares assumed purchased with the proceeds available from
     such exercise. Fully diluted net income per share does not differ
     materially from net income per common share and common share equivalent.

     Fair Value of Financial Instruments
     -----------------------------------

     The carrying amounts of cash, accounts receivable, and accounts payable
     approximate fair value because of the short maturity of these financial
     instruments. The carrying amounts of long-term debt approximate fair value
     because either interest rates fluctuate based on market rates or interest
     rates appear to approximate market rates for similar instruments.

     New Authoritative Pronouncements
     --------------------------------

     In February 1997, the Financial Accounting Standards Board (FASB) issued
     Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings Per
     Share," which establishes new standards for computing and presenting
     earnings per share. This statement will be adopted by the Company for the
     1998 fiscal year.

     In February 1997, the FASB issued SFAS No. 129, "Disclosure of Information
     about Capital Structure," which establishes standards for disclosing
     information about an entity's capital structure. This statement will be
     adopted by the Company for the 1998 fiscal year.

     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
     Income," which establishes standards for reporting and display of
     comprehensive income and its components. This statement will be adopted by
     the Company for the 1999 fiscal year.

     In June 1997, the FASB issued SFAS No. 131, "Disclosures About Segments of
     an Enterprise and Related Information," which establishes standards for
     reporting and disclosure of financial information by segment. This
     statement will be adopted by the Company for the 1999 fiscal year.

3.   Line of Credit
     --------------

The Company has a $2,500,000 unsecured line of credit with a bank. At June 30,
1997, the entire amount was available under this credit arrangement, which
expires on June 20, 1999. Borrowings under this facility bear interest at the
bank's reference rate (8.5 percent at June 30, 1997). The line of credit
agreement includes certain restrictive covenants which are discussed in Note 4
below.

5.   Income Taxes
     ------------

The Company accounts for income taxes in accordance with SFAS No. 109.

Under SFAS No. 109, deferred income tax assets or liabilities are computed based
on the temporary difference between the financial statement and income tax bases
of assets and liabilities using the enacted marginal income tax rate in effect
for the year in which the differences are expected to reverse. Deferred income
tax expenses or credits are based on the changes in the deferred income tax
assets or liabilities from period to period.

The exercise of stock options which have been granted under the Company's
various stock option plans give rise to compensation which is includable in the
taxable income of the applicable employees and deductible by the Company for
federal and state tax purposes. Such compensation results from increases in the
fair market value of the Company's common stock subsequent to the date of grant
of the applicable exercised stock options. Accordingly, in accordance with
Accounting Principles Board Opinion No. 25 (APB 25), such compensation is not
recognized as an expense for financial accounting purposes and the related tax
benefits are taken directly to shareholders' equity. The tax benefits arising
from the exercise of stock options were approximately $170,000 in 1997 and not
material in 1996 and 1995.

The components of the deferred income tax asset at June 30, 1997 and 1996 are
as follows:

7.   Employee Stock Options
     ----------------------

In 1988, the Company established an Employee Stock Option Plan under which
options to purchase a total of 275,000 shares of common stock may be granted to
certain employees as determined by the Company's Board of Directors. Options
granted under this plan vest in equal amounts on the first and second
anniversary dates of the granting of the options. At June 30, 1997, there were
no options outstanding under this plan.

In 1993, the Company established the 1993 Stock Option Plan, which provides for
granting options to purchase up to 250,000 shares of the Company's common stock
to employees, officers, directors and consultants of the Company. Options to
purchase 160,000 shares have been granted and are outstanding under this plan at
June 30, 1997, of which 133,334 are exercisable, expiring at various dates
through November 11, 2006. These options generally vest over a three-year period
from the date of the grant.

In 1995, the Company established the 1995 Stock Option Plan, which provides for
granting options to purchase up to 250,000 shares of the Company's common stock.
Options to purchase 65,000 shares have been granted and are outstanding under
this plan at June 30, 1997, of which none are exercisable, expiring at various
dates through January 28, 2007. These options generally vest over a three-year
period from the date of the grant.

All options have been granted at prices equal to the fair market value of the
common stock at the grant date. A summary of option activities for all plans is
as follows:

In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation," which applies the fair value-based method of accounting for
options granted under stock-based compensation plans beginning fiscal 1997. In
accordance with the issued standard, the Company has elected to continue to
account for stock-based compensation in accordance with APB 25.

The weighted average fair value of options granted during 1997 was $2.76. The
fair value of each option granted is estimated by using the Black-Scholes
pricing model on the date of grant. The following assumptions were used in the
calculation of present value: risk-free interest rate of 5.4 to 5.8 percent,
expected lives of five to six years, expected volatility of 37 percent and no
expected dividends.

Had compensation cost for the Company's stock option plans been determined
consistent with SFAS No. 123, the Company's net income and earnings per share
would have been reduced to the following pro forma amounts:

8.   Employee Benefit Plans
     ----------------------

API provides a profit-sharing plan and 401(k) plan for its employees. The Board
of Directors can authorize discretionary contributions with no required minimum
contribution. API's contribution to the profit-sharing plan for the periods
ended June 30, 1997, 1996 and 1995 was $120,000 for each period. There were no
API contributions to the 401(k) plan for the periods ended June 30, 1997, 1996
and 1995.

9.   Contingencies
     -------------

    Environmental Matters
    ---------------------

    The Company formerly operated a facility on property within the boundaries
    of a federal Superfund site located in Southern California. The Company
    operated at this site prior to October 1986. The Company has learned that
    hazardous substances have been identified in the subsurface of the property
    and that the current owner has been requested by a state agency to undertake
    additional investigation at the property. The Company is also 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 may be held responsible for the contamination at the site to the
    extent the Company caused the contamination. The Company does not believe
    that it is responsible for any material contamination and has not been
    notified or contacted by the government or named in any proceeding relating
    to the property. The potential liability associated with this property
    cannot be reasonably determined at this time.

    Tax Examination
    ---------------

                                      F-32
<PAGE>
 
      API is in the process of an Internal Revenue Service (IRS) examination
      regarding the tax-exempt status of its industrial revenue bond.  The IRS
      has informed the Company that preliminary findings indicate that the bond
      may not be tax exempt and thus API may be required to pay additional
      interest.  The Company believes it has recorded adequate reserves to cover
      any potential liability that may result from the final resolution of this
      matter.

10.  Subsequent Event
     ----------------

On July 2, 1997, Summa Industries (Summa) signed a definitive agreement to
purchase all outstanding stock of the Company for $7.35 per share in cash. This
agreement is subject to shareholder approval and Summa's ability to obtain
financing for the transaction.

              SUMMA AND CALNETICS PROFORMA FINANCIAL INFORMATION

                               SUMMA INDUSTRIES
        UNAUDITED PROFORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The accompanying unaudited proforma condensed consolidated financial statements
reflect the acquisition by SUMMA of all the issued and outstanding capital stock
of Calnetics as a consequence of the merger of a wholly-owned subsidiary of
SUMMA with and into Calnetics. The transaction will be accounted as a purchase
by SUMMA of the net assets of Calnetics.

The unaudited proforma condensed consolidated balance sheet is based upon
SUMMA's historical audited consolidated balance sheet at August 31, 1997 and
Calnetic's historical audited balance sheet as of June 30, 1997, and is
presented as if the transaction had been consummated on August 31, 1997.

The unaudited proforma condensed consolidated statement of income for the year
ended August 31, 1997 gives effect to the merger of the subsidiary and Calnetics
as if the transaction had occurred at September 1, 1996, the beginning of
SUMMA's fiscal year ended August 31, 1997. The unaudited proforma condensed
consolidated income statement combines the audited historical consolidated
results of operations of SUMMA for the year ended August 31, 1997 and the
audited historical results of the operations of Calnetics for the year ended
June 30, 1997.

The proforma adjustments are based upon available information and upon certain
assumptions which the management of SUMMA believes are reasonable. However, the
unaudited proforma condensed consolidated financial statements do not purport to
be indicative of the results which would have been achieved if the transaction
had been completed on the respective dates above or the results which may be
achieved in the future.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Shareholders of Summa Industries:

We have audited in accordance with generally accepted auditing standards, the
consolidated financial statements included in Summa Industries and subsidiaries'
annual report to shareholders included in this Form 10-K, and have issued our
report dated October 6, 1997. Our audit was made for the purpose of forming an
opinion on those statements taken as a whole. The schedule listed in the index
of consolidated financial statements is the responsibility of the Company's
management and is presented for purposes of complying with the Securities and
Exchange Commission's rules and is not part of the basic consolidated financial
statements and, in our opinion, fairly states in all material respects the
financial data required to be set forth therein in relation to the basic
consolidated financial statements taken as a whole.

Borrower may from time to time repay all or a portion of the amounts outstanding
under the Revolving Loan (together with accrued interest to the date of
repayment on the principal amount so repaid), which amounts may be re-borrowed
(subject to the Revolving Commitment Limit and the Available Amount) so long as
the Commitment of the Lenders to make Advances under the Revolving Loan has not

Loan (an "Advance"), each Lender is hereby authorized to record, on its books

any payment of the Obligations when due.

shall be payable concurrently with principal.   At its option, Borrower may from
time to time prepay all or any portion of the outstanding principal of the Term
Loan, together with accrued interest on the principal being so prepaid and any
amount payable pursuant to Section 3.7.  Borrower shall be entitled to designate
                           -----------                                          
the scheduled principal payments to which any partial voluntary prepayment under
the Term Loan is to be applied; in such event Borrower shall pay accrued
interest on the outstanding principal of the Term Loan on the payment dates when
such prepaid principal payments would otherwise have been due.

     2.3 Purpose Line.   Lenders agree to provide Borrower with a non-revolving
         ------------

shall be available for disbursement pursuant to the Purpose Line following the
third (3rd) anniversary of the Closing Date, at which time the Purpose Line
Commitment shall terminate as to any future Loans thereunder.  Each loan
advanced under the Purpose Line shall be evidenced by one or more Purpose Notes,

                                  ---------                 ------------

the Purpose Line may be used to finance up to 90% of the purchase price of new
equipment, up to 80% of the purchase price of used equipment and up to 90% for
the acquisition of other businesses, each of which shall be subject to the prior
approval of Agent.  Principal of each loan made pursuant to the Purpose Line
shall be repaid as provided in Section 3.3.  In addition, at its option,

later than the last Business Day immediately preceding the date of the requested
Advance, and shall specify the date and amount of the requested Advance, the
Interest Period therefor, and whether such Advance is to bear interest with
reference to LIBOR or the Floating Rate for such Interest Period.  All Borrowing
Requests and confirmations thereof in writing or by facsimile must be signed by
an officer of Borrower who has been identified in writing to Agent as an officer
authorized to make Borrowing Requests on behalf of Borrower. Notwithstanding the
foregoing, in the case of the Purpose Line, Borrowing Requests shall be
accompanied by sufficient documentation for Agent and the Lenders to evaluate
the assets or business the Borrower proposes to acquire with the proceeds of the
requested loan, including any applicable purchase orders, equipment
specifications and acquisition agreements, and such Borrowing Requests and
documentation shall be delivered sufficiently in advance of the proposed date of
disbursement to permit Agent and the Lenders to evaluate the acquisition to be
financed by the requested loan.

     2.5  Lenders' Records.  With respect to each Loan, each Lender is hereby

written notice to Agent, Borrower may from time to time, on any Business Day,
effect a permanent reduction of the Revolving Commitment Limit; provided,
                                                                -------- 
however, that

          (i)  to the extent that the outstanding Revolving Loan would exceed
     the Available Amount after giving effect to the requested reduction,
     Borrower shall, concurrently with the reduction of the Revolving Commitment
     Limit, make a prepayment of the Revolving Loan in an amount sufficient to
     cause Borrower to be in compliance with the Available Amount after giving
     effect to such reduction; and

          (ii)  each such reduction in the Total Commitment shall be in an
     aggregate minimum amount of $500,000 and an integral multiple of $25,000.

Each reduction of the Revolving Commitment Limit shall reduce, pro-rata, the
Lenders' respective portions of the Revolving Commitment Limit.

plus the Applicable Base Rate Margin (the "Floating Rate") or, at Borrower's

per annum equal to the sum of LIBOR plus the Applicable LIBOR Margin (the "LIBOR
                                                                           -----
Rate"); provided, that following the occurrence of an Event of Default, all

amounts outstanding under each Facility shall, at the option of Agent, bear
interest at the rate per annum equal to the sum of the Floating Rate then
applicable to such Facility plus 3%.  A portion of principal outstanding
hereunder bearing interest at the Floating Rate shall be referred to as a
"Floating Rate Loan"; and a portion of principal outstanding hereunder bearing

interest at the LIBOR Rate shall be referred to as a "LIBOR Loan".  With respect
                                                      ----------

Floating Rate Loan.  Borrower may at any time convert a Floating Rate Loan into
a LIBOR Loan.  At the time any advance is requested under a Facility, and/or
Borrower wishes to have the LIBOR Rate apply to all or a portion of the
outstanding principal of the Loans, and at the end of each Interest Period,
Borrower shall give Agent notice specifying (i) the interest rate option
selected by  Borrower, (ii) the principal amount to be subject to such interest
rate, and (iii) if the LIBOR Rate is selected, the length of the applicable
Interest Period.  Any such notice may be given by telephone so long as, in the
case of LIBOR Loans, (x) Agent received written confirmation of such telephonic
notice not later than three (3) Business Days after such telephonic notice is
given, and (y) such notice is given to Agent prior to 10:00 a.m., California
time, on the first day of the requested Interest Period.  Notwithstanding the
foregoing, Borrower may only request the LIBOR Rate with respect to the
Revolving Loan, and only for amounts of principal that are at least $500,000 in
the aggregate and integral multiples of $100,000.  If, upon any request to have
the LIBOR Rate apply to any portion of the Loans, Borrower does not immediately
accept the LIBOR Rate quoted by Agent, any subsequent acceptance by Borrower
shall be subject to a redetermination of the LIBOR Rate by Agent; provided that
                                                                  --------     
if Borrower fails to accept any such quotation as given, then the quoted rate
shall expire and Agent shall be under no obligation to permit Borrower to select
the LIBOR Rate on such day.   With respect to any portion of the Loans for which
the LIBOR Rate has not been duly selected in accordance with the foregoing
provisions of this Section 3.1, Borrower will be deemed to have selected the
                   -----------                                              
Floating Rate.  Each portion of the Loans bearing interest at the LIBOR Rate
must remain outstanding for the Interest Period selected for such portion of the
Loans by Borrower.

     3.2  Interest Payments and Computations.  Accrued interest on all
          ----------------------------------                          
outstanding Loans shall be due and payable on the last Business Day of each
month.  Interest on LIBOR Loans shall be computed on the basis of a 360-day year
and shall be assessed for the actual number of days elapsed from the first day
of the applicable Interest Period, but excluding the last day of such period.
Interest on each Floating Rate Loan shall be computed on the basis of a 360-day
year and shall be assessed for the actual number of days elapsed.

     3.3  Principal Payments.  The outstanding principal of the Loans shall be

connection therewith.  All Net Cash Proceeds received by Borrower and its
Subsidiaries in excess of $250,000 in the aggregate in any fiscal year (or, in
the case of Net Cash Proceeds derived from the issuance or sale by Borrower of
any of its equity interests or any issuance of indebtedness which is subordinate

Proceeds, Agent (at the direction of  Lenders holding at least 66 2/3% of the

debt that would otherwise be treated as "current portions" under GAAP as of the
date of determination, regardless of whether any such installments have been
prepaid) and Capital Expenditures incurred but not financed during the
applicable period, all calculated excluding any accounting items in respect of
Net Cash Proceeds received during the most recently ended fiscal year that were
applied in accordance with Section 3.3(d).  Such prepayment shall be applied

against the remaining installments of the Term Loan on a pro-rata basis based
upon the number and amounts of such installments.

          (f)  Anything herein to the contrary notwithstanding, the aggregate
outstanding principal amount of the Revolving Loan shall not at any time exceed
the Available Amount as from time to time determined (in accordance with the
most recently delivered Borrowing Base Certificate), and no Advance may be
requested unless after giving effect thereto  Borrower is in compliance with
foregoing requirement.  In the event that the aggregate outstanding principal
amount of the Revolving Loan shall at any time and for any reason (including,
without limitation, a decrease in the amount of the Borrowing Base) exceed the
Available Amount then in effect, Borrower shall, without notice or demand, pay
not later than the Business Day after the date such excess is determined the
amount of such excess to Agent as a prepayment of the principal amount of the

of any LIBOR Loan on a date other than the scheduled last day of the Interest
Period applicable thereto, for any reason, or (b) any loans not being made as

its Subsidiaries to, create or acquire any other Subsidiary (a "New Subsidiary")

     8.3  Remedies with Respect to Collateral.
          ----------------------------------- 

          (a)  Without limiting the foregoing, if any Event of Default shall
occur and be continuing,  Agent may exercise, in addition to all other rights
and remedies granted to it in this Agreement, any other Loan Document or by law,
all rights and remedies of a secured party under the UCC.  Without limiting the
generality of the foregoing, Borrower expressly agrees that in any such event
Agent may, without demand of performance or other demand, advertisement, legal
process or notice of any kind (except as may be required by law or provided
herein) to or upon 

                                       49
<PAGE>
 
Borrower or any other Person (all and each of which demands, advertisements
and/or notices are hereby expressly waived to the maximum extent permitted by
the UCC and other applicable law), (i) at any time or times enter Borrower's
premises and take physical possession of the Collateral and maintain such
possession on Borrower's premises, without any obligation to pay rent or other
compensation to Borrower, (ii) remove the Collateral or any part thereof, to
such other places as Agent may desire, (iii) forthwith collect, receive,
appropriate and realize upon the Collateral, or any part thereof, and/or (iv)
forthwith sell, lease, assign, give an option or options to purchase, or sell or
otherwise dispose of and deliver said Collateral (or contract to do so), or any
part thereof, in one or more parcels at public or private sale or sales, at any
exchange or broker's board or at any of Agent's offices or elsewhere at such
prices and on such terms as Agent may deem commercially reasonable (irrespective
of the impact of any such sales on the market price of the Collateral), for cash
or on credit or for future delivery. Any such purchaser (including, without
limitation, Agent and any other Lender) of Collateral sold pursuant to this
Section 8.3 shall purchase the same absolutely free from any claim or right on
- -----------
the part of Borrower and Borrower does hereby waive (to the maximum extent
permitted by the UCC and other applicable law) all rights of redemption, stay,
and appraisal which Borrower now has or may at any time in the future have under
any rule of law or statute now existing or hereafter enacted. Borrower further
agrees, at Agent's request to assemble the Collateral and make it available to
Agent at places which Agent shall reasonably select, whether at Borrower's
premises or elsewhere. To the maximum extent permitted by applicable law,
Borrower waives all claims, damages, and demands against Agent arising out of
the repossession, retention or sale of the Collateral except such as may arise
out of the gross negligence or willful misconduct of Agent or the failure of
Agent to exercise reasonable care in the custody and preservation of Collateral
in its possession or under its control as provided in Section 4.3. Borrower
                                                      -----------
agrees that, to the extent notice of sale shall be required by law, Agent need
not give more than ten (10) days' notice of the time and place of any public
sale or of the time after which a private sale may take place and that such
notice shall constitute reasonable notification within the meaning of Section
9504(3) of the UCC.

          (b)  Borrower also agrees to pay all reasonable costs of Agent and
Lenders, including, without limitation, reasonable attorneys' fees, incurred in
connection with the enforcement of any of its rights and remedies hereunder,
including, without limitation, reasonable fees for attorneys employed by  Agent
or any Lenders to collect any deficiency existing after the application of
proceeds from any sale of Collateral pursuant to this Section 8.3.
                                                      ----------- 

          (c)  Borrower hereby waives presentment, demand, protest or any notice
(to the maximum extent permitted by applicable law) of any kind in connection
with this Agreement or any Collateral.

          (d)  The proceeds of any disposition of any Collateral obtained
pursuant to this Section 8.3 and\or the other Loan Documents shall be applied as
                 -----------                                                    
follows:

               (i)  first, to the payment of any and all expenses and fees
     (including reasonable attorney's fees) incurred by  Agent in foreclosing on
     and disposing of the Collateral;

               (ii) next, any surplus then remaining to the payment of the
     Obligations (whether matured or unmatured) in such order as Agent may
     determine in its sole discretion; and

                                       50
<PAGE>
 
               (iii) thereafter, if no other Obligations are outstanding, any
     surplus then remaining shall be paid to Borrower or to such other Person
     legally entitled to same; it being understood that Borrower will remain
     liable to Agent and the Lenders to the extent of any deficiency between the
     amount of the Obligations and the aggregate of all amount realized from
     Collateral.


9.   THE AGENT
     ---------

     9.1  Actions.  Each Lender hereby appoints COMERICA BANK-CALIFORNIA
          -------                                                       
("Comerica") as its Agent under and for purposes of this Agreement and each
 ----------                                                                 
other Loan Document.  Each Lender authorizes Agent to act on behalf of such
Lender under this Agreement and each other Loan Document and, in the absence of
other written instructions from the Required Lenders received from time to time
by Agent (with respect to which Agent agrees that it will comply, except as
otherwise provided in this Section or as otherwise advised by counsel), to
exercise such powers hereunder and thereunder as are specifically delegated to
or required of  Agent by the terms hereof and thereof, together with such powers
as may be reasonably incidental thereto. Each Lender hereby indemnifies (which
indemnity shall survive any termination of this Agreement) Agent, pro rata
                                                                  --- ----
according to such Lender's Percentage, from and against any and all liabilities,
obligations, losses, damages, claims, costs or expenses of any kind or nature
whatsoever which may at any time be imposed on, incurred by, or asserted
against, Agent in any way relating to or arising out of this Agreement and any
other Loan Document, including reasonable attorneys' fees, and as to which Agent
is not reimbursed by Borrower; provided, however, that no Lender shall be liable
                               --------  -------                                
for the payment of any portion of such liabilities, obligations, losses,
damages, claims, costs or expenses which are determined by a court of competent
jurisdiction in a final proceeding to have resulted solely from Agent's gross
negligence or wilful misconduct.  Agent shall not be required to take any action
hereunder, or under any other Loan Document, or to prosecute or defend any suit
in respect of this Agreement  or any other Loan Document, unless it is
indemnified hereunder to its satisfaction.  If any indemnity in favor of Agent
shall be or become, in Agent's determination, inadequate, Agent may call for
additional indemnification from the Lenders and cease to do the acts indemnified
against hereunder until such additional indemnity is given.

     9.2  Funding Reliance, etc.  Unless Agent shall have been notified by
          ---------------------                                           
telephone, confirmed in writing, by any Lender by 5:00 p.m., Pacific time, on
the day prior to an Advance or Purpose Line disbursement that such Lender will
not make available the amount which would constitute its Percentage of such
Advance or disbursement on the date specified therefor, Agent may assume that
such Lender has made such amount available to Agent and, in reliance upon such
assumption, make available to Borrower a corresponding amount.  If and to the
extent that such Lender shall not have made such amount available to Agent, such
Lender and Borrower severally agree to repay Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
Agent made such amount available to Borrower to the date such amount is repaid
to Agent, at the interest rate applicable at the time to the portion of the
Revolving Loan comprising such Advance or to such Purpose Line disbursement, as
the case may be.

     9.3  Exculpation.  Neither Agent nor any of its directors, officers,
          -----------                                                    
employees or agents shall be liable to any Lender for any action taken or
omitted to be taken by it under this Agreement or any other Loan Document, or in
connection herewith or therewith, except for its own wilful misconduct or gross
negligence, nor responsible for any recitals or warranties herein or therein,

                                       51
<PAGE>
 
nor for the effectiveness, enforceability, validity or due execution of this
Agreement or any other Loan Document, nor for the creation, perfection or
priority of any Liens purported to be created by any of the Loan Documents, or
the validity, genuineness, enforceability, existence, value or sufficiency of
any collateral security, nor to make any inquiry respecting the performance by
Borrower or any of its Subsidiaries of their respective obligations under the
Loan Documents.  Any such inquiry which may be made by Agent shall not obligate
it to make any further inquiry or to take any action.  Agent shall be entitled
to rely upon advice of counsel concerning legal matters and upon any notice,
consent, certificate, statement or writing which  Agent believes to be genuine
and to have been presented by a proper Person.

     9.4  Successor.  Agent may resign as such at any time upon at least 30
          ---------                                                        
days' prior notice to Borrower and all Lenders.  If Agent at any time shall
resign, the Required Lenders may appoint another Lender as a successor Agent
which shall thereupon become Agent hereunder.  If no successor Agent shall have
been so appointed by the Required Lenders, and shall have accepted such
appointment, within 30 days after the retiring Agent's giving notice of
resignation, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent, which shall be one of the Lenders or a commercial banking
institution organized under the laws of the U.S. (or any State thereof) or a
U.S. branch or agency of a commercial banking institution, and having a combined
capital and surplus of at least $50,000,000.  Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
be entitled to receive from the retiring Agent such documents of transfer and
assignment as such successor Agent may reasonably request, and shall thereupon
succeed to and become vested with all rights, powers, privileges and duties of
the retiring Agent, and the retiring Agent shall be discharged from its duties
and obligations under this Agreement.  After any retiring Agent's resignation
hereunder as Agent, the provisions of this Section 9 shall inure to its benefit
                                           ---------

provisions of this Section 10.2; provided that no such assignment or

participation shall be permitted if after giving effect thereto, there would be,
in the aggregate, more than four (4) Lenders and Participants hereunder

          (a)  Assignments.  Any Lender may at any time, with notice to Borrower

delegation shall be of a constant, and not a varying, percentage of all the
assigning Lender's Commitment and shall be allocated ratably among the Revolving
Loan, the Term Loan and the Purpose Line); provided, however, that Borrower and
                                           --------  -------                   
Agent shall be entitled to continue to deal solely and directly with such Lender
in connection with the interests so assigned and delegated to an Assignee Lender
until (i) written notice of such assignment and delegation, together with
payment instructions, addresses and related information with respect to such
Assignee Lender, shall have been given to Borrower and Agent by such Lender and
such Assignee Lender; and (ii) Agent shall have received its customary
processing fee from such Lender or Assignee Lender and an executed assignment
agreement in form and substance satisfactory to Agent.  Notwithstanding the
foregoing, not less than 50% of the aggregate Commitments shall at all times be

deemed automatically to have become a party hereto and to the extent that rights
and obligations hereunder have been assigned and delegated to such Assignee
Lender in connection with such assignment, shall have the rights and obligations
of a Lender hereunder and under the other Loan Documents, and (y) the assignor
Lender, to the extent that rights and obligations hereunder have been assigned
and delegated by it in connection with such assignment, shall be released from
its obligations hereunder and under the other Loan Documents.  Within 5 Business
Days after its receipt of notice of such assignment, Borrower shall execute and
deliver to Agent (for delivery to the relevant Assignee Lender) new Notes
evidencing such Assignee Lender's assigned Commitment and, if the assignor
Lender has retained a Commitment hereunder, replacement Notes each in the
principal amount of the applicable Loan retained by the assignor Lender
hereunder (each such Note to be in exchange for, but not in payment of, the Note
then held by such assignor Lender).  Each such replacement Note shall be dated
the date of the predecessor Note.  The assignor Lender shall mark the
predecessor Note "exchanged" and deliver it to Borrower.  Accrued interest on
that part of the predecessor Note evidenced by the replacement Note, and accrued
fees, shall be paid as provided in the documentation effecting the Assignment.
Accrued interest on that part of the predecessor Note evidenced by the Revolving
Note shall be paid to the assignor Lender.  Accrued interest and accrued fees
shall be paid at the same time or times provided in the predecessor Note and in
this Agreement.  Any attempted assignment and delegation not made in accordance
with this Section 10.2(a) shall be null and void.

     relieve such Lender from its Commitment or its other obligations hereunder
     or under any other Loan Document;

     Lender, or is itself a Lender, shall be entitled to require such Lender to
     take or refrain from taking any action hereunder or under any other Loan
     Document, except that such Lender may agree with any Participant that such
     Lender will not, without such Participant's consent, take any actions of
     the type described in clause (b) or (c) of Section 10.6.
                           ----------    ---    ------------ 

Borrower acknowledges and agrees that each Participant, for purposes of Sections
                                                                        --------

     10.7 Set Offs.  Upon the occurrence and during the continuance of any Event
          --------                                                              
of Default, Agent and each Lender is hereby authorized at any time and from time
to time, without notice to Borrower (any such notice being expressly waived by
Borrower), to set off and apply to the payment of the Obligations (whether or

from and against any and all actions, causes of action, suits, losses, costs,
liabilities and damages, and expenses incurred in connection therewith
(irrespective of whether any such Indemnified Party is a party to the action for
which indemnification hereunder is sought), including reasonable attorneys' fees
and disbursements (collectively, the "Indemnified Liabilities"), incurred by the
                                      -----------------------

reason, Borrower hereby agrees to make the maximum contribution to the payment

when executed and delivered, shall be deemed to be an original, and all of
which, when taken together, shall constitute but one and the same Agreement.

      10.12 Integration. This Agreement, together with the other Loan Documents,

any act, delay, omission or otherwise be deemed to have waived any of its rights
or remedies hereunder, and no waiver shall be valid unless in writing, signed by
Agent and the Lenders and then only to the extent expressly provided therein.  A
waiver by  Agent and the Lenders of any right or remedy hereunder on any one

the Lenders would otherwise have had on any future occasion.  No failure to
exercise nor any delay in exercising on the part of  Agent and the Lenders, any
right, power or privilege hereunder, shall operate as a waiver thereof, nor
shall any single or partial exercise of any right, power or privilege hereunder
preclude any other or future exercise thereof or the exercise of any other
right, power or privilege.  The rights and remedies hereunder provided are
cumulative and may be exercised singly or concurrently, and are not exclusive of
any rights and remedies provided by law.

      10.14 GOVERNING LAW. THIS AGREEMENT, THE NOTES AND ALL OTHER LOAN

            --------------------                                               
THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED.
EACH OF THE PARTIES HERETO HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY
WAIVES (AFTER CONSULTING OR HAVING THE OPPORTUNITY TO CONSULT WITH COUNSEL OF
THEIR CHOICE) ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY
LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF
DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY HERETO.
