                                October 17, 1996



Dear Shareholder:

I am pleased to invite you to attend SUMMA INDUSTRIES' Annual Meeting of
Shareholders which will be held on Thursday, November 21, 1996.  In addition to
the election of directors, you are being asked  to vote on the merger of a new
subsidiary of SUMMA INDUSTRIES with and into LexaLite International Corporation
of Charlevoix, Michigan which will become a wholly-owned subsidiary of SUMMA
INDUSTRIES, upon shareholder approval of the merger.  LexaLite is a manufacturer
of engineered plastic optical components.

SUMMA INDUSTRIES' Board of Directors voted UNANIMOUSLY in favor of the merger
                                           -----------                       
with LexaLite, and recommends that shareholders vote FOR this proposal.
                                                     ---               

This transaction, which follows our recent divestiture of Morehouse-COWLES,
Inc., will complete the transformation of SUMMA INDUSTRIES from a machinery
builder to a manufacturer of proprietary industrial components -- primarily of
plastic materials.  I believe this transaction is the most important event in
SUMMA's 54-year history.  It will more than double the number of shares
outstanding, without diluting earnings per share (on an historical pro-forma
basis), and create an enterprise with substantially increased sales, profit and
net worth.  I URGE YOU TO CAREFULLY REVIEW THE ENCLOSED PROXY STATEMENT AND JOIN
ME IN VOTING FOR THE LEXALITE MERGER.
             ---                     

THE DETAILS OF THE MERGER, INCLUDING INFORMATION ABOUT LEXALITE, SUMMA AND
VARIOUS RISK FACTORS, ARE DISCUSSED IN THE ENCLOSED JOINT PROXY
STATEMENT/PROSPECTUS AND NOTICE OF ANNUAL MEETING OF SHAREHOLDERS.

YOUR VOTE IS IMPORTANT.  This transaction can only be approved if more than 50%
- ----------------------                                                         
of all outstanding shares are voted FOR the merger.  Therefore, if you do not
                                    ---                                      
vote, it will have the same effect as voting against the merger.  PLEASE READ
THE ENCLOSED PROXY STATEMENT, AND MARK, SIGN, DATE AND MAIL YOUR PROXY TODAY.
Your prompt response will help SUMMA save the money associated with follow-up
solicitation efforts.


                                      Very truly yours,

                                      James R. Swartwout

      described in the Joint Proxy Statement/Prospectus;

  (2) To elect three directors to serve 3-year terms if the Merger is approved

                                October 17, 1996     



Dear Stockholder:
    
  You are cordially invited to attend a special meeting of stockholders of
LexaLite International Corporation ("LexaLite") to be held at 10:00 a.m., local
time, on November 16, 1996 at the Charlevoix Country Club, one-quarter (1/4)
mile east of Waller Road, on U.S. 31, north of Charlevoix.      
    
  At this Special Meeting, you will be asked to approve the merger (the
"Merger") of a wholly-owned subsidiary of Summa Industries, a California
corporation, with and into LexaLite pursuant to the Agreement of Merger attached
as Appendix I to the Joint Proxy Statement/Prospectus which accompanies this
letter.  Also enclosed herewith is a copy of the Agreement and Plan of
Reorganization dated as of July 18, 1996 by and between Summa and LexaLite.  As
a consequence of the Merger, the outstanding shares of LexaLite Common Stock
will be converted into shares of Summa Common Stock.  The Board of Directors of
LexaLite has carefully reviewed and considered the terms and conditions of the
Merger and has received the opinion of Wedbush Morgan Securities as to the
fairness of the Merger to the stockholders of LexaLite from a financial point of
view.  The full text of the opinion of Wedbush Morgan is attached as Appendix II
to the Joint Proxy Statement/Prospectus.  All of the Directors on the Board of
LexaLite have joined in concluding that the Merger is fair to, and in the best
interests of, LexaLite and its stockholders and we recommend that you vote FOR
approval of the Merger.      
    
  If the Merger is approved and consummated, LexaLite will become a wholly-owned
subsidiary of Summa, and each share of LexaLite Common Stock outstanding at the
time the Merger becomes effective will be converted into 1.5 shares (subject to
possible upward adjustment) of Summa Common Stock, all as more fully described
in the accompanying Joint Proxy Statement/Prospectus and the Agreement and Plan
of Reorganization.  The Merger is discussed in both and you are urged to review
them carefully.     
    
  Under Delaware law, the Merger must be approved by the affirmative vote of the
holders of at least a majority of the outstanding shares of LexaLite Common
Stock.  Your vote is important!  Therefore, whether or not you personally will
attend the Special Meeting, please vote by promptly completing, signing, dating
and mailing the enclosed proxy form.  You may always revoke your proxy at or
before the time of the Special Meeting should you wish to vote in person.      

  PLEASE DO NOT SEND IN ANY STOCK CERTIFICATES AT THIS TIME.  Promptly after the
Merger is consummated, you will be sent instructions regarding the mechanics of
exchanging LexaLite stock certificates, that are currently in your possession,
for the new certificates representing shares of Summa Common Stock.
    
                                    Warm regards,

                                    LEXALITE INTERNATIONAL CORPORATION

Agreement").  Upon consummation of the Merger, which would be effective upon
filing of the Merger Agreement, or a certificate of merger with respect thereto,
in the offices of the Secretaries of State of California and Delaware,
Subsidiary would be merged with and into LexaLite, which would be the surviving
corporation in the Merger and which would continue to carry on the business and
affairs of LexaLite as a wholly-owned subsidiary of Summa.  As a consequence of
the Merger, the former stockholders of LexaLite would receive an aggregate of
2,252,241 shares (subject to possible upward adjustment) of Summa's Common
Stock.  In addition, the Articles of Incorporation of Summa will be amended to
establish a 9-member Board of Directors divided into three classes serving
staggered 3-year terms, and Summa would adopt the LexaLite Employee Stock
Ownership Plan, as amended.  See "Description of the Proposed Merger."

                      ANNUAL MEETING OF SUMMA SHAREHOLDERS
    
      Proxies are being solicited by the Board of Directors of Summa for use at
the Annual Meeting of the Shareholders of Summa (the "Summa Annual Meeting") to
be held at 2:00 p.m., local time, at the Mariott Hotel, 3635 Fashion Way,

and into LexaLite International Corporation, a Delaware corporation
("LexaLite"), all as more particularly described herein and in the Notice of
Annual Meeting accompanying this Joint Proxy Statement/Prospectus.  In approving
the Merger, the shareholders of Summa will also approve, among other things, an

shareholders of Summa also will be asked to elect three directors to serve 3-
year terms, including two incumbent directors whose terms are expiring and Josh
T. Barnes, the Chief Executive Officer and a director of LexaLite, and three
additional incumbent directors to serve 2-year terms.  If the Merger is not
approved, only the four incumbent directors whose terms are expiring will be
nominated for election to serve as directors for new 2-year terms.  The record
date for determining the shareholders of Summa entitled to notice of and to vote
at the Summa Annual Meeting is October 14, 1996.      

                    SPECIAL MEETING OF LEXALITE STOCKHOLDERS
    
      Proxies are being solicited by the Board of Directors of LexaLite for use
at a Special Meeting of the Stockholders of LexaLite (the "LexaLite Special
Meeting") to be held at 10:00 a.m., local time, at the Charlevoix Country Club,
located at 9600 Clubhouse Drive, Charlevoix, Michigan 49720, on November 16,
1996, and at any continuation or adjournment thereof, for the purpose of
considering and voting upon the proposed Merger, as more particularly described
herein and in the Notice of Special Meeting accompanying this Joint Proxy
Statement/Prospectus.  The record date for determining the stockholders of
LexaLite entitled to notice of and to vote at the LexaLite Special Meeting is
October 14, 1996.      

                              THE PROPOSED MERGER

      Pursuant to the Reorganization Agreement dated as of July 18, 1996, Summa
and LexaLite have agreed, subject to the approval of the shareholders of Summa
and the stockholders of LexaLite and the satisfaction of certain other
conditions, that Subsidiary will merge with and into LexaLite on the terms and
conditions more particularly described herein.
    
SUMMA       Summa is a publicly-owned California corporation whose Common Stock
            is registered under Section 12(g) of the Securities Exchange Act of
            1934, as amended, and traded on The Nasdaq National Market under the
            symbol, "SUMX".  Through its two wholly-owned operating
            subsidiaries, Summa designs and manufacturers 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.  As of October 14, 1996, the record date for the Summa
            Annual Meeting, 1,603,483 shares of the Common Stock of Summa were
            issued and outstanding.     

                                       5

LEXALITE    LexaLite is a privately held Delaware corporation headquartered in
            Charlevoix, Michigan. LexaLite designs and manufactures injection-
            molded plastic optical components for OEM customers in the lighting
            industry. As of October 14, 1996, the record date for the LexaLite
            Special Meeting, 1,479,672 shares of the Common Stock of LexaLite
            were issued and outstanding (excluding 21,822 shares earned and
            issuable under the LexaLite Stock Award Bonus Plan).     
    
SUBSIDIARY  Charlevoix the Beautiful, Inc. is a California corporation which
            has recently been organized as a wholly-owned subsidiary of Summa
            solely for the purpose of entering into the Merger.  As a
            consequence of the Merger, Subsidiary will merge with and into
            LexaLite which, as the surviving corporation in the Merger, will
            continue to conduct its business and operations as a wholly-owned
            subsidiary of Summa.     
    
REASONS FOR In 1991, Summa adopted a strategy of growth through acquisitions of
THE MERGER  profitable manufacturing companies with proprietary products or
            protected market niches. The acquisition of LexaLite as a
            consequence of the Merger will be the third such acquisition that
            Summa has accomplished. For the past several years, the LexaLite
            Board of Directors has considered various strategic alternatives to
            maximize stockholder value and increase liquidity, while preserving
            the culture of the organization and considering the interests of
            employees, customers and the community. The LexaLite Board evaluated
            an initial public offering, outside equity investment, and potential
            business combinations with other companies. The LexaLite Board
            determined that the proposed transaction with Summa offered the best
            opportunity available to fulfill the Board's strategic objectives.
     
            The acquisition of LexaLite as a consequence of the Merger will
            provide Summa with a third operating subsidiary, thereby enabling
            Summa to further expand its operations by adding additional product
            offerings.  Among other perceived benefits to the Summa
            shareholders, the number of shares of Summa Common Stock in the
            public float, as well as the number of Summa shareholders, will
            increase significantly, which may enhance the marketability of the
            Summa Common Stock and provide increased liquidity for all Summa
            shareholders.   Even though the number of outstanding shares will
            increase substantially, the acquisition of LexaLite is not expected
            to be dilutive of Summa's earnings per share.

            The stockholders of LexaLite will retain the opportunity to continue
            to share in any growth of LexaLite's businesses that might be
            achieved following the Merger, although the value of their
            investment will no longer be dependent solely upon the success or
            failure of LexaLite, since the market value of the shares of Summa's
            Common Stock that they will receive as a consequence of the Merger
            will reflect the results of operations in several different
            businesses.  In addition, by receiving registered stock of a
            publicly-held company, it is believed that the stockholders of
            LexaLite will be better able to liquidate some or all of their
            investment when they choose to do so.  Moreover, since the Merger is
            intended to qualify as a "tax-free reorganization", no taxable event
            should occur unless and until a former LexaLite stockholder decides
            to sell at a future date shares of the Summa Common Stock received
            as a consequence of the Merger.  Management of both Summa and
            LexaLite believes that the shareholders of each company will benefit
            from the proposed Merger.
    
TERMS OF    Upon the Effective Date (as defined below) of the Merger, Subsidiary
THE MERGER  will be merged with and into LexaLite, and each outstanding share of
            LexaLite's Common Stock will be converted into one and one-half
            (1.5) shares of Summa's Common Stock, such that the holders of
            LexaLite's Common Stock immediately prior to the Merger will
            receive, as a group, an aggregate of 2,252,241 shares of Summa's
            Common Stock (including 32,733 shares earned and issuable under the
            LexaLite Stock Award Bonus Plan). If the average closing price of
            Summa's Common Stock for the 5-day trading period ending three days
            prior to the LexaLite Special Meeting is less than

                $6.66, LexaLite may terminate the transactions contemplated by
                the Reorganization Agreement unless Summa agrees to increase the
                number of shares of Summa's Common Stock issuable as a
                consequence of the Merger to that total number which would have
                an aggregate market value (based on such average closing price)
                of $15,000,000. See "Description of the Proposed Merger - Manner
                and Basis of Converting Shares."

                of $8.13 per share, will be exchanged for options to purchase up
                to 156,825 shares of Summa's Common Stock, for the same
                aggregate exercise prices. See "Description of the Proposed
                Merger -Treatment of Stock Options." In addition, Summa has
                agreed to issue 30,000 additional shares of Summa Common Stock
                to a financial intermediary for services rendered in connection
                with the proposed Merger.     
    
                Accordingly, the former stockholders of LexaLite as a group
                would own approximately 58% of the 3,855,724 shares of Summa's
                Common Stock to be outstanding immediately following the Merger,
                before taking into account the total of 156,825 shares issuable
                upon exercise of the options to purchase Summa's Common Stock
                that will be held by former stockholders of LexaLite following
                the Merger. The percentage ownership by the former stockholders
                of LexaLite would be decreased upon the exercise of options to
                purchase up to 425,000 shares of Summa's Common Stock granted or
                to be granted under Summa's stock option plans (options to
                purchase 245,473 shares are currently outstanding), and upon the
                issuance of additional shares of Summa's Common Stock following
                the Merger, if any, to make further acquisitions or raise
                additional equity capital.     
    
FAIRNESS        Wedbush Morgan Securities ("Wedbush Morgan") has delivered to
OPINION         the Boards of Directors of both LexaLite and Summa a written
                opinion dated as of October 11, 1996, to the effect that, based
                upon and subject to various considerations set forth in the
                opinion, the Merger is fair from a financial point of view to
                both the stockholders of LexaLite and the shareholders of Summa.
                A copy of the opinion of Wedbush Morgan, which sets forth the
                assumptions made, matters considered and the scope of their
                review, is attached to this Joint Proxy Statement/Prospectus as
                Appendix II and should be read in its entirety. See "Description
                of the Proposed Merger -Fairness Opinion."     
    
CONDITIONS TO   Consummation of the Merger is subject to various conditions,
THE MERGER;     including, among others, approval of the Merger by the
AMENDMENT;      shareholders of Summa and the stockholders of LexaLite, and the
TERMINATION     receipt of any required regulatory approvals. The Reorganization
                Agreement and the Merger Agreement may each be amended by
                written agreement of each of the parties before approval by the
                Summa shareholders and the LexaLite stockholders, as well as
                thereafter if such amendment would not materially and adversely
                affect the shareholders of Summa or the stockholders of
                LexaLite, as the case may be. These agreements may also be
                terminated and the Merger abandoned before the Effective Date by
                the mutual consent of the Boards of Directors of each of the
                parties, or by the Board of Directors of either party if the
                Merger has not been consummated by January 31, 1997, except that
                the foregoing right to terminate is not available to a party
                whose failure to perform any covenant or condition within that
                party's control is the proximate cause of the failure of the
                Merger to be consummated by that date. In addition, the
                Reorganization Agreement and the transactions contemplated
                thereby may be terminated by either LexaLite or Summa in the
                event that the Board of Directors of either has determined that
                consummation of the Merger could reasonably be expected to cause
                the directors of the terminating party to violate their
                fiduciary duties under applicable law. Any termination as
                described in the preceding sentence would be conditioned upon
                payment by the terminating party to the other of the sum of
                $500,000, as liquidated damages in respect of the loss of the
                non-terminating party's prospective economic opportunity, plus
                reimbursement of all out-of-pocket expenses reasonably incurred
                by the non-terminating party through the date of such
                termination. See "Description of the Proposed Merger-Additional
                Conditions to the Merger; Amendment or Termination."

CERTAIN         Based upon certain assumptions, it is expected that the merger
FEDERAL         will constitute a tax-free reorganization under Section 368 of
INCOME TAX      the Internal Revenue Code of 1986, as amended (the "Code"), such
CONSEQUENCES    that (i) the stockholders of LexaLite who receive shares of
                Summa's Common Stock will reorganize no gain or loss for federal
                income tax purposes as a cnsequence of the Merger, (ii) the tax
                basis of Summa's Common Stock received by those shareholders
                will be the same as the tax basis of the shares of LexalIte's
                Common Stock exchanged therefor, and (iii) the holding period of
                Summa's Common Stock received will include the holding period of
                LexaLite's Common Stock exchanged therefor. However, no opinions
                of counsel or rulings from the Internal Revenue Service have
                been or will be obtained as to any of the federal tax
                consequences of the Merger. See "Description of the Proposed
                Merger -- Certain Federal Income Tax Considerations."

COMPARISON      The rights of holders of Summa Common Stock differ in certain
OF RIGHTS OF    respects from the rights of holders of LexaLite Common Stock,
LEXALITE AND    including the fact that Summa is subject to the informational
SUMMA           requirements of the Exchange Act and that Summa Common Stock is
SHAREHOLDERS    traded on The Nasdaq national Market. See "Description of
                Securities -- Comparison of Rights of LexaLite and Summa
                Shareholders."

RESALE OF       The shares of Summa's Common Stock to be received by the
SUMMA COMMON    stockholders of LexaLite as a consequence of the Merger will be
STOCK           registered under the Securities Act of 1933, as amended (the
                "Securities Act") and thus will be freely transferable by all of
                the former stockholders of lexaLite except for those former
                stockholders who become "affiliates" of Summa following the
                Merger. See "Description of the Merger -- Affiliate's
                Restrictions on Resale of Summa's Common Stock."


DISSENTERS'     Holders of LexaLite's Common Stock who object to the Merger may
RIGHTS          under certain circumstances, and by following prescribed
                statutory procedures, receive cash for their shares. The failure
                of a dissenting shareholder to follow such procedures, described
                more fully elsewhere in this Joint Proxy Statement/Prospectus,
                may result in termination or waiver of rights as a dissenter.
                The Merger may be terminated by Summa in the event that the
                holders of more than 2% of LexaLite's Common Stock perfect their
                dissenters' rights as described herein. See "Description of the
                Proposed Merger - Rights of Dissenting LexaLite Stockholders."
    
RECENT MARKET   The Common Stock of Summa is traded on The Nasdaq National
PRICES          Market. On July 18, 1996, the last full trading day prior to the
                public announcement by Summa and LexaLite of their mutual
                execution of the Reorganization Agreement, the closing sale
                price for a share of Summa's Common Stock was $6.00. On October
                11, 1996, the closing price for a share of Summa's Common Stock
                on The Nasdaq National Market was $6.13. See "Summa Common Stock
                Prices and Dividends."     
    
EFFECTIVE DATE  The Merger will be consummated if and on such date as the
                executed Merger Agreement is filed with the California Secretary
                of State and a certificate of merger with respect thereto is
                filed with the Delaware Secretary of State (the "Effective
                Date"). The Effective Date is currently expected to occur on or
                shortly after November 21, 1996, the date of the Summa Annual
                Meeting, subject to approval of the Merger by the Summa
                shareholders and the LexaLite stockholders and the satisfaction
                or waiver of the other conditions to the Merger. See
                "Description of the Proposed Merger - The Merger."      
    
RECOMMENDATIONS The Boards of Directors of Summa and LexaLite have both
                Unanimously approved the Merger as in the best interests of
                their respective corporations, shareholders and stockholders,
                and have recommended that the Merger be approved by their
                respective shareholders and stockholders.      
     
VOTE            The affirmative vote of holders of a majority of the outstanding
REQUIRED        shares of both the Summa Common Stock and the LexaLite Common
                Stock is required to approve the merger. Of the 1,603,483 shares
                of Summa's Common Stock outstanding as of the record date for
                the Summa Annual meeting, directors and executive officers of
                Summa who owned or had voting control over an aggregate of
                247,356 shares, or approximately 15.4%, have indicated their
                intention to vote in

                favor of the proposed Merger. The affirmative votes of the
                holders of an additional 554,386 shares of Summa's Common Stock
                will be required for approval of the Merger by the shareholders
                of Summa. Of the 1,479,672 shares of LexaLite's Common Stock
                outstanding as of the record date for the LexaLite Special
                Meeting, the directors and executive officers of LexaLite owned
                or had voting control over approximately 48.9%. Each of these
                directors and executive officers has indicated an intention to
                vote in favor of the proposed Merger. The affirmative votes of
                the holders of an additional 15,562 shares of LexaLite's Common
                Stock will be required for approval of the Merger by the
                stockholders of LexaLite.    

AMENDMENT       In approving the Merger, the shareholders of Summa will also
OF SUMMA        approve an amendment to the Articles of Incorporation of Summa
ARTICLES OF     to establish a 9-member Board of Directors divided into three
INCORPORATION;  classes serving staggered 3-year terms. Summa's Board of
ELECTION OF     Directors currently consists of eight members divided into two
DIRECTORS       classes, with half of the members elected to serve 2-year terms
                at each annual meeting. If the Merger is approved and
                consummated, Josh T. Barnes, the Chief Executive Officer and a
                director of LexaLite, will be nominated for election at the
                Summa Annual Meeting to serve as a director of Summa for a 3-
                year term, along with two incumbent directors of Summa whose
                current terms are expiring, and three additional incumbent
                directors will be elected to serve new 2-year terms. Otherwise,
                only the four incumbent directors whose terms are expiring will
                be nominated for election at the Summa Annual Meeting, each to
                serve new 2-year terms. See "Description of the Proposed Merger-
                Approval of the Merger."

ADOPTION OF     In approving the Merger, the shareholders of Summa also will
LEXALITE        approve the adoption by Summa of the Employee Stock Ownership
ESOP            Plan ("ESOP") of LexaLite, as amended, so that the ESOP Trustee
                will be required to purchase shares of Summa's Common Stock in
                the market whenever it receives a cash contribution to the ESOP.
                Alternately, Summa will be able to make direct contributions of
                Common Stock to the ESOP as determined by the Board of
                Directors. Additionally, Summa would be able, but not obligated,
                to expand the ESOP to include employees of other Summa
                subsidiaries.

                                  RISK FACTORS

  In evaluating whether to approve the Merger, the stockholders of LexaLite and
the shareholders of Summa should carefully consider the following factors in
addition to the other information presented in this Joint Proxy
Statement/Prospectus and the documents incorporated by reference herein.  The
statements contained in this Joint Proxy Statement/Prospectus 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 "Risk
Factors" portion of this Joint Proxy Statement/Prospectus as well as those set
forth elsewhere in this Joint Proxy Statement/Prospectus.  The forward-looking
statements are made as of the date of this Joint Proxy Statement/Prospectus and
neither Summa nor LexaLite assumes any 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.

GROWTH THROUGH ACQUISITIONS STRATEGY; MANAGEMENT OF GROWTH

  Although Summa has been in business for more than 50 years, prior to 1991 it
was engaged in only one business, the manufacture of 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 for growth through acquisitions
of profitable manufacturing companies with proprietary products or protected
market niches.  See "Description of the Proposed Merger - Purpose and Background
of the Merger."  GST Industries, Inc. was acquired in 1991 and KVP Systems, Inc.
was acquired in 1993.  In June 1996, the unprofitable process equipment business
was sold.  Therefore, although GST and KVP had each been established for over 15
years prior to their acquisition by Summa, the continuing businesses of Summa
have been operating under their current ownership structure for only five years
and three years respectively.  For these reasons, among others, 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 two years.

    The success of Summa's strategy for growth through acquisitions will depend
to a large extent on the ability of Summa to identify suitable candidates for
acquisition, and to negotiate acceptable terms and conditions upon which a
target company would be acquired.  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.  Although typically the existing
management of an acquired company would be retained to manage day to day
operations, it is anticipated that the business of an acquired company could be
expanded through enhanced financial, marketing and administrative support to be
furnished by the executive officers of Summa.  However, 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, including the former stockholders of LexaLite.
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.

INTEGRATION OF BUSINESSES

  Since it is expected that the operations of LexaLite will not be combined with
those of any of Summa's other operating subsidiaries as a consequence of the
Merger, the achievement of most of the perceived advantages of the Merger 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, 

                                       12
<PAGE>
 
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 no changes in either company's operations,
marketing or sales following the Merger, that the combined entities will be able
to attain shareholder values greater than if the two companies operated
independently, or that the other perceived benefits of the Merger will be
realized.

BUSINESS CONCENTRATION RISK
    
  LexaLite sells its products and services primarily to manufacturers of
lighting fixtures, of which there is a limited number.  As a consequence, a
significant portion of LexaLite sales are to a relatively-few customers.  See,
"Information Concerning LexaLite - Markets."  GST, although its sales will
represent only approximately 4% of the combined company's sales, has a high
concentration of sales for one airplane system even though several customers are
involved.  That airplane, the F-16, is very mature and sales of parts for it are
expected to decline.  The largest customer of any unit of the consolidated
company will represent approximately 10% of combined company's sales and there
can be no assurance that sales to several significant customers might not be
simultaneously adversely effected.      

FLUCTUATIONS IN REVENUES AND EARNINGS

  Although none of the businesses to be conducted by Summa following the Merger
are 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,
economic conditions generally, including the availability of credit, as well as
market conditions particular to various of the industries in which Summa
products are sold, can be expected to 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.

GENERAL RISKS OF BUSINESS

  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, changes in general economic
conditions, increases in operating costs including costs of production,
supplies, personnel, equipment, import duties and transportation, reduced
margins caused by competitive pressures and other factors, and increases in
governmental regulation imposed under federal, state or local laws, including
regulations applicable to environmental, labor and trade matters.

COMPETITION; NEW PRODUCT DEVELOPMENT; PROPRIETARY RIGHTS

  The markets for each of the products that will be manufactured and sold by
each of Summa's operating subsidiaries following the Merger are characterized by
extensive competition.  There are a number of companies that currently offer
competing products, and it can be expected that additional competing products
will be introduced by other companies in the future.  Many of Summa's existing
and potential competitors have greater financial, marketing, and research
capabilities than Summa.  The performance of Summa will depend on the ability of
Summa 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 Summa were to incur delays in developing new
products or if such products did not gain market acceptance.  Therefore, there
can be no assurance that Summa's existing or future products will be
sufficiently successful to enable Summa to effectively compete in its
prospective market or, should Summa's product offerings meet with significant
customer acceptance, that one or more current or future competitors will not
introduce products which render Summa's products noncompetitive.  Both Summa and
LexaLite hold numerous patents on products which they have developed or
acquired.  The extent to which these patents provide a commercial advantage or
inhibit the development of competing products 

                                       13
<PAGE>
 
varies. To a large extent, however, Summa will be required to rely upon common
law concepts of confidentiality and trade secret laws, 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.

DEPENDENCE ON MANAGEMENT

  Implementation of Summa's strategy for growth through acquisitions will depend
to a significant extent upon the continued services of Mr. Swartwout and his
ability to identify appropriate candidates for acquisition, to negotiate deals
acceptable to the Board of Summa and the shareholders of Summa, and supervise
the management of a variety of operating subsidiaries.  Summa also will continue
to depend upon other members of its senior administrative staff, and upon the
continuing services of the key management employees of each of the companies it
acquires.  The loss of the services of one or more of these key employees could
have a material adverse affect upon Summa.  All of LexaLite's executive officers
have indicated their intention to continue in their present positions.  However,
there can be no assurance that Summa will be successful in retaining its key
employees, or in attracting and retaining any additional personnel it requires.

KEY TECHNICAL PERSONNEL

  Several key engineers who have designed many of Summa's products are in the
latter stages of their careers.  Karl V. Palmaer was the founder of KVP Systems,
Inc. and is now a product development consultant to and a director of Summa.
Robert L. Green founded GST Industries, Inc. and is currently its President and
a Vice President of Summa.  Josh T. Barnes founded LexaLite and is currently its
Chief Executive Officer.  After the Merger, Mr. Barnes will be on the Board of
Directors of Summa and will serve on a consulting basis at LexaLite.  Messrs.
Palmaer, Green and Barnes are 75, 74 and 68 years old, respectively.  There is
no assurance that these key individuals will continue to contribute at the same
level in the future that they do currently and there is no assurance that the
product inventors and designers within Summa and LexaLite, or inventors and
designers recruited in the future, can perform those functions as innovatively
and effectively as these three individuals.

SALE OF DISCONTINUED OPERATIONS

  On June 17, 1996, Summa sold all of the issued and outstanding capital stock
of Morehouse-COWLES, Inc., the subsidiary through which Summa had conducted its
process equipment business since 1991, when Summa embarked on its strategy of
growth through acquisitions.  For the nine months ended May 31, 1996, Morehouse-
COWLES, Inc. operated at a loss before income taxes of approximately $421,000,
on sales of approximately $5,638,000.  In connection with the sale, Summa
received $750,000 in cash, a ten-year subordinated promissory note, in the
original principal amount of $1,771,000, that is secured by a pledge of both the
stock and assets of Morehouse-COWLES, Inc., and a ten-year lease on Summa's
facilities in Fullerton, California.  See "Summa Management's Discussion and
Analysis of Summa's Results of Operations and Financial Condition - Sale of
Discontinued Operations."  In the event that the new owners of Morehouse-COWLES,
Inc. are unable to return its operations to a level of profitability sufficient
to meet the obligations incurred in the transaction, there is a risk that the
new owners may default in payments under the lease or on the subordinated note
given as part of the purchase price, in which event Summa might incur
substantial losses and/or be required to foreclose on the note and resume the
responsibility for the business and operations of Morehouse-COWLES, Inc. which
could be encumbered by debt owed by the new owners, including amounts borrowed
to finance the purchase of the stock of Morehouse-COWLES, INC. from Summa.

LITIGATION

  Summa has encountered lawsuits from time to time in the ordinary course of its
business.  See, "Information Concerning Summa - Legal Proceedings."  Although
Summa has obtained 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 which have been filed against Summa
in the past have contained claims the subject of which was not covered by
insurance.  Such excluded 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, may have a
material adverse impact on the financial condition and prospects of Summa.

LIMITED PRIOR MARKET; POSSIBLE VOLATILITY OF SUMMA'S STOCK PRICE; SHARES
ELIGIBLE FOR FUTURE SALE
    
  Prior to this offering, there has been a limited public market for Summa's
Common Stock.  As of October 14, 1996, there were 1,603,483 shares of Summa's
Common Stock outstanding, of which a total of 1,356,127 shares were held by non-
affiliates of Summa.  For the first nine months of 1996, the closing sales price
for a share of Summa's Common Stock ranged from a low of $3.88  to a high of
$6.25, on an average weekly trading volume of approximately 17,600 shares.  On
October 11, 1996, the closing price for a share of Summa's Common Stock on the
Nasdaq National Market was $6.13.  The effective price per share at which shares
of Summa's Common Stock will be issued as a consequence of the Merger should not
be considered an indication of any price at which Summa's Common Stock may trade
in the future.  The market price of Summa's Common Stock will be subject to
change as a result of market conditions and other factors and no assurance can
be given that Summa's Common Stock can be resold at a price equal to or greater
than the price at the time of the Merger.  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.
See "Summa Common Stock Prices and Dividends."     
    
  Although the number of shares of Summa's Common Stock outstanding in the
public float, and the number of Summa shareholders will increase significantly
following the Merger, there can be no assurance that a more active trading
market for the Summa Common Stock will develop or be sustained following the
Merger.  Moreover, since the shares issuable as a consequence of the Merger
generally will be freely tradeable, sales of these shares by former stockholders
of LexaLite may cause substantial fluctuations in the market price of Summa's
Common Stock over short time periods.  A number of the former stockholders of
LexaLite have indicated an intention to sell, as soon as practicable following
the Merger, all or a portion of the shares of Summa's Common Stock issuable to
them as a consequence of the Merger.  In addition, of the 1,529,895 shares of
Summa's Common stock currently outstanding which were issued more than three
years ago, 1,312,926 are not held by "affiliates" of Summa, and can therefore be
sold under Rule 144 without regard to the volume limitations thereof.  Summa has
also registered 421,000 shares issuable upon exercise of options granted and to
be granted under its stock option plans.  Sales of substantial amounts of
Summa's Common Stock by the former stockholders of LexaLite, under Rule 144 or
otherwise, or even the potential for such sales, could have a depressive effect
on the market price of shares of  Summa's Common Stock and could impair Summa's
ability to raise capital through the sale of its equity securities.     

ABILITY TO ISSUE PREFERRED STOCK; ANTI-TAKEOVER DEVICES
    
  Summa is authorized to issue up to 5,000,000 shares of Preferred Stock in one
or more series, the terms of which may be determined at the time of issuance by
the Board of Directors, without further action by Summa's shareholders, and may
include voting rights, preferences as to dividends and liquidation, conversion
and redemptive rights and sinking fund provisions.  Although Summa has no
present plans to issue any additional shares of Preferred Stock, the issuance of
Preferred Stock in the future could affect the rights of the holders of Summa's
Common Stock and thereby reduce the value of the Common Stock.  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.  In
addition, 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.     

LACK OF DIVIDENDS.

  Summa has not paid any cash dividends on its Common Stock since 1983 and does
not anticipate that it will pay dividends in the foreseeable future.  Instead,
Summa intends to apply any earnings to the expansion and development of its
business.  See "Summa Common Stock Prices and Dividends."

                               VOTING AND PROXIES 
    
  As of October 14, 1996, the record date for the determination of the
shareholders of Summa entitled to notice of, and to vote at, the Summa Annual
Meeting, there were 1,603,483 shares of Summa's Common Stock outstanding, which
were held of record by a total of 484 shareholders.  Each share entitles the
holder to one vote on each matter to come before the Summa Annual Meeting.     
    
  As of October 14, 1996, the record date for the determination of the
stockholders of LexaLite entitled to notice of, and to vote at, the LexaLite
Special Meeting, there were 1,479,672 shares of LexaLite's Common Stock
outstanding (excluding 21,822 shares earned and issuable under the LexaLite
Stock Award Bonus Plan), which were held of record by a total of 44
stockholders, including the LexaLite ESOP.  Each share entitles the holder to
one vote on each matter to come before the LexaLite Special Meeting.     

  The presence in person or by proxy of the holders of a majority of the
outstanding shares of Summa's Common Stock and LexaLite's Common Stock is
necessary to constitute a quorum for purposes of transaction of business at the
Summa Annual Meeting and the LexaLite Special Meeting, respectively.  The
affirmative vote of the holders of a majority of the outstanding shares of
Summa's Common Stock and the affirmative vote of the holders of a majority of
the outstanding shares of LexaLite's Common Stock is required to approve the
proposed Merger.  Abstentions, failures to vote and broker non-votes will not be
counted as votes either in favor of or against approval of the proposed Merger.
Because approval of the proposed Merger requires the affirmative vote of a
majority of outstanding shares of Summa Common Stock and LexaLite Common Stock,
however, a Summa shareholder or a LexaLite stockholder who fails to return a
proxy or otherwise to vote or who abstains from voting on the proposed Merger
will have effectively voted against the proposal for purposes of determining the
number or votes needed for approval.

  In the event that the shareholders of Summa approve the Merger, three
individuals will be nominated by the Board of Directors of Summa for election to
serve 3-year terms on the Board of Directors, including Messrs. Horst and
Swartwout, incumbent directors whose terms are expiring as of the Summa Annual
Meeting, and Josh T. Barnes, the Chief Executive Officer and a director of
LexaLite. In addition, three additional incumbents, Messrs. Morris, Palmaer and
Roth will be nominated for election to serve new 2-year terms on the Summa Board
of Directors.  Should the shareholders of Summa fail to approve the Merger, only
the four incumbent directors whose terms are expiring, Messrs. Morris, Horst,
Swartwout and Palmaer will be nominated for election to new 2-year terms on the
Board of Directors of Summa.  In accordance with Summa's Articles of
Incorporation, there will be no cumulative voting for the election of directors.
Accordingly, the six nominees (if the Merger is approved) or four nominees (if
the Merger is not approved), as the case may be, receiving the highest number of
votes at the Summa Annual Meeting, will be elected.  In the event that the
Merger is not consummated for any reason, despite the approval thereof by the
shareholders of Summa, the amendment of Summa's Articles of Incorporation to
establish a 9-member classified board of directors will not be implemented and
only the four incumbent directors whose terms are expiring will deemed to have
been elected to the Summa Board of Directors, each to serve a new 2-year term.

  Proxies for use at the Summa Annual Meeting and at the LexaLite Special
Meeting accompany copies of this Joint Proxy Statement/Prospectus.  Properly
executed and returned proxies, unless revoked, will be voted as directed by the
Summa Shareholder or the LexaLite Stockholder, as the case may be, or, in the
absence of such direction, by the persons named therein FOR the approval of the
proposed Merger in accordance with the recommendation of the Board of Directors
of each of Summa and LexaLite and FOR the election as a director of Summa of
each individual nominated therefor by the Board of Directors of Summa.  As to
any other business which may properly come before either the Summa Annual
Meeting or the LexaLite Special Meeting, the proxy holders will vote in
accordance with their best judgment.  A proxy may be revoked at any time before
it is voted by delivery of written notice of revocation to the Secretary of
Summa or the Secretary of LexaLite, as the case may be, or by delivery of a
subsequently dated proxy, or by attendance at the Summa Annual Meeting or the
LexaLite Special Meeting and voting in person.  Attendance at the Summa Annual
Meeting or the LexaLite Special Meeting without also voting will not in and of
itself constitute the revocation of a proxy.
    
  The respective costs of soliciting proxies will be borne by Summa and
LexaLite.  It is expected that proxies will be solicited by LexaLite exclusively
by mail.  Summa has engaged The Altman Group, Inc. to assist Summa in soliciting
proxies.  In addition, if it should appear desirable to do so, directors,
officers and employees of Summa or LexaLite may communicate with their
respective shareholders and stockholders, and with banks, brokerage houses,
nominees and others by telephone, telegraph, or in person, to request that
proxies be furnished.

                       DESCRIPTION OF THE PROPOSED MERGER

  The following information with respect to the proposed Merger does not purport
to be complete and is qualified in its entirety by reference to the
Reorganization Agreement and related Merger Agreement.

                     PURPOSE AND BACKGROUND OF THE MERGER

SUMMA STRATEGY FOR GROWTH THROUGH ACQUISITIONS
- ----------------------------------------------

  In 1991, Summa adopted a strategy of growth through acquisitions, 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 will 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.
    
  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.  GST has two divisions, the Stang
Industrial Products Division 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.  As the purchase price for the
stock of GST, Summa paid an aggregate $2.3 million in cash, and gave the GST
shareholders 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, through August 31, 1996, the
former shareholders of GST have earned contingent performance payments in the
cumulative aggregate amount of $2,025,000.  The obligation for the contingent
payments expires October 31, 1996.  The acquisition was partially funded by
borrowings under Summa's credit facility with Community Bank, which were
subsequently repaid.     

  At the time of the GST acquisition, Summa also formed a wholly-owned
subsidiary, Morehouse-COWLES, Inc., to which it transferred all of the operating
assets of its industrial process equipment business.  In June 1996, Morehouse-
COWLES, Inc. was subsequently sold to a private investment group.  See "Summa
Management's Discussion and Analysis of Summa's Results of Operation and
Financial Condition - Sale of Discontinued Operations."

  In July  1993, Summa acquired all of the outstanding capital stock of KVP
Systems, Inc. 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.  In addition, Karl V. Palmaer,
the founder of KVP, joined the Board of Directors of Summa, on which he
continues to serve.

  Consequently, upon consummation of the Merger, Summa will have three wholly-
owned operating subsidiaries, GST Industries, Inc., KVP Systems, Inc. and
LexaLite International Corporation.  In evaluating future acquisitions, Summa
will endeavor to identify target companies that manufacture 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 affect on post-acquisition, consolidated earnings per
share.  In addition, 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 day to day operations of the target company following the
acquisition.  Perhaps most importantly, Summa will seek to determine that there
is a significant likelihood that the acquisition can be expected to result in a
sustainable increase in earnings per share within 12 months of the closing.

INTRODUCTION OF SUMMA AND LEXALITE
- ----------------------------------
    
  Following more than thirty years of continuing success in the design,
fabrication and marketing of components to the Lighting Industry, including
several recent years of growth and expansion, the LexaLite Board of Directors
considered several strategic directions for LexaLite.  Criteria considered
critical in their evaluations included liquidity of stock, without the expense
and uncertainty of a public offering, fair value for stockholders, avoidance of
a taxable event, and, most importantly, assurance that any considered
transaction would reasonably continue the growth of LexaLite's ongoing business
in the same locations and minimal personnel disruption.     

  Indications of interest in all, or substantially all, of LexaLite's stock or
assets were evaluated by its Board over a period of time, with each being
discarded or declined due to not meeting all required conditions and not being
in the best interest of stockholders and employees.

  Late in 1995, a broker, familiar with Summa, became aware that LexaLite was
willing to evaluate a transaction that met their criteria.  In January of 1996,
the broker introduced Summa to LexaLite, with subsequent visits by Mr. Swartwout
and Mr. Barnes to their respective facilities in California and Michigan.
Negotiations occurred over a period of six months, during which time LexaLite
considered other offers and negotiated with other potential buyers.  On May 7,
1996, Summa made a first formal offer to acquire LexaLite on a stock-for-stock
basis.

  Following extensive negotiations and a number of revisions to the terms
originally proposed by Summa, on May 11, 1996, an Agreement in Principle was
approved by the Boards of Directors of both parties.  On July 18, 1996, Summa
and LexaLite executed the Definitive Reorganization Agreement which provides,
among other things, for the acquisition of all of LexaLite's outstanding stock
through the merger (the "Merger") of a newly formed and wholly owned subsidiary
of Summa ("Subsidiary") with and into LexaLite.
    
  As a consequence of the Merger, the shareholders of LexaLite will receive
shares of Summa's Common Stock which together will constitute approximately 58%
of the shares of Summa's Common Stock to be outstanding immediately following
the Merger. The percentage of shares of Summa's Common Stock to be received by
the stockholders of LexaLite as a consequence of the Merger, in relation to the
percentage of such outstanding shares to be retained by the current shareholders
of Summa immediately following the Merger, was determined as the result of
negotiations between the management of Summa and the management of LexaLite.  In
the course of such negotiations, numerous factors were taken into consideration
by both Summa and LexaLite, including recent market prices for shares of Summa's
Common Stock, an evaluation of the assets, obligations, operations and earnings
of, and judgments with respect to the prospects for, both Summa and LexaLite,
and other offers for the purchase of LexaLite, with each party giving varying
degrees of emphasis upon such factors.  In addition, the respective Board of
Directors of each company also gave consideration to certain internal
projections by the management of both Summa and LexaLite.  These internal
projections were based upon assumptions and estimates which the respective
management of the two companies believe to be reasonable, but are not included
herein nor intended as public representations of future performance by either
party.     

REASONS FOR THE MERGER
- ----------------------

  Management of Summa believes that the acquisition of LexaLite through the
proposed Merger is consistent with the Summa strategy for growth through
acquisitions.  Among other perceived benefits to the Summa shareholders, the
number of shares of Summa's Common Stock in the public float, as well as the
number of Summa shareholders, will increase significantly.  As reflected in the
table under the caption." Summa and LexaLite Comparative Per Share Data," the
acquisition of LexaLite is not expected to be dilutive of Summa's earnings per
share.  Although no assurance can be given, for these and other reasons it is
anticipated that the public market for Summa's Common Stock will be enhanced,
thereby providing increased liquidity for the shareholders of Summa.

  Because the primary manufacturing technology of LexaLite, injection-molding of
engineering plastic components, is the same as that of Summa's largest
subsidiary, KVP Systems, Inc., this transaction will give Summa the opportunity
to develop a strategic focus for future business development and acquisitions --
"engineered plastic components for

                                       20
<PAGE>
 
industrial and commercial markets."  This focus will increase the likelihood
that operating synergies could be achieved from future acquisitions.
Additionally, the investment community may perceive the combined company as a
business with a strategic focus as opposed to a conglomerate, which may result
in a higher valuation of Summa's stock.

  The combined company will have substantially more shares outstanding and
substantially higher sales, earnings, assets and net worth than Summa has now.
The increased size of the enterprise could make investment in the shares of
Summa attractive to some institutional investors who might currently not
consider the stock.  This could increase the demand for the stock, resulting in
more liquidity and higher stock prices.

  LexaLite will have enhanced access to capital for continued growth in the
future.  Since Summa has negligible debt, the combined company will have a
substantially stronger consolidated balance sheet than LexaLite has alone, which
will result in increased borrowing capacity.  Additionally, because the combined
company will be publicly traded, it could raise additional capital by a
subsequent equity offering.  Also, LexaLite has an ESOP which is required to buy
back any of the stock distributed to employees if they so demand.  Since the
combined company will be publicly traded, this requirement will be eliminated
(after a three-year contractual extension).  This will eliminate a long-term
commitment, the required funds for which can instead be reinvested in the
business.

  The Merger is expected to provide the stockholders of LexaLite with many of
the same benefits as are anticipated would be realized by the shareholders of
Summa.  For example, the stockholders of LexaLite will retain the opportunity to
continue to share in any growth of LexaLite's business that might be achieved
following the Merger, although the value of their investment will no longer be
dependent solely upon the success or failure of LexaLite, since the market value
of the shares of Summa's Common Stock that they will receive as a consequence of
the Merger will reflect the results of operations in several different
businesses.  In addition, by receiving registered stock of a publicly-held
company, it is believed that the stockholders of LexaLite will be better able to
liquidate some or all of their investment when they choose to do so.  Moreover,
since the Merger is intended to qualify as a "tax-free reorganization", no
taxable event should occur unless and until a former LexaLite stockholder
decides to sell, at a future date, shares of Summa's Common Stock received as a
consequence of the Merger.  LexaLite's Board of Directors also considered
Summa's stated intention that, after consummation of the Merger, LexaLite's
corporate headquarters will remain in Charlevoix, Michigan, and that LexaLite's
business will be carried on under its present name and with substantially the
same management at its present facilities.


                                   THE MERGER

  Subject to the conditions and the termination provisions contained in the
Reorganization Agreement, the proposed Merger will become effective at the time
and on the date on which the Merger Agreement and a certificate of merger with
respect thereto, along with any other required documents, are duly filed with
the Secretary of State of California and the Secretary of State of Delaware,
respectively.  It is currently anticipated that, if the proposed Merger is
approved by the shareholders of Summa at its Annual Meeting and the stockholders
of LexaLite at its Special Meeting, and all other conditions of the Merger have
been fulfilled or waived, the Effective Date will occur on the date that the
Summa Annual Meeting has been scheduled, or a date as soon as practicable
thereafter.  Upon consummation of the Merger, Subsidiary will merge with and
into LexaLite.  As a result of the Merger, Subsidiary as a corporation will
cease to exist and LexaLite will remain as the surviving corporation and a
wholly-owned subsidiary of Summa, and each currently outstanding share of
LexaLite's Common Stock will automatically be converted into shares of Summa's
Common Stock on the basis described below.

                     MANNER AND BASIS OF CONVERTING SHARES

  If the Merger is consummated, the Reorganization Agreement provides that each
outstanding share of LexaLite's Common Stock, other than any shares constituting
"dissenting shares" under Section 262 of the Delaware General Corporate Law,
will on the Effective Date be converted into one and one-half (1.5) shares of
Summa's Common Stock.  However, in the event that the average closing price of
Summa's Common Stock on The Nasdaq National Market is less than $6.66 per share
during the 5 consecutive trading days ending on and including the third trading
day prior to the date 

                                       21
<PAGE>
 
of the LexaLite Special Meeting, LexaLite may notify Summa of LexaLite's
intention to terminate the Reorganization Agreement and the transactions
contemplated thereby unless Summa agrees, as described below, to increase the
number of shares of Summa's Common Stock issuable to the stockholders of
LexaLite as a consequence of the Merger. Upon receipt of such notification,
Summa may elect either to terminate the Reorganization Agreement or to increase
the number of shares of Summa's Common Stock issuable to the stockholders of
LexaLite as a group to that total number of shares which would have an aggregate
value (based upon the average closing price calculated as described above) equal
to $15,000,000. Summa has indicated that it is unlikely that Summa would elect
to increase the number of shares of Summa's Common Stock issuable as a
consequence of the Merger if the increased number of shares would exceed
3,000,000, including shares to be issuable upon exercise of options to be held
by former option-holders of LexaLite. The conversion of shares of LexaLite's
Common Stock into shares of Summa's Common Stock will occur on the Effective
Date by operation of law, without any action on the part of the holder thereof
and without regard to the date on which certificates formerly representing
shares of LexaLite's Common Stock are physically surrendered, or on which
certificates for shares of Summa's Common Stock are delivered to former LexaLite
stockholders.

  As soon as practicable after the Effective Date, a letter of transmittal will
be mailed to each former stockholder of LexaLite containing instructions with
respect to the surrender of LexaLite stock certificates to U.S. Stock Transfer
Corporation, which will act as Exchange Agent for the former stockholders of
LexaLite, in exchange for certificates representing the number of shares of
Summa's Common Stock into which their LexaLite shares have been converted.
However, it will not be necessary for stockholders of LexaLite to exchange their
existing stock certificates for stock certificates of Summa.  In the event that
a transfer of shares of LexaLite's Common Stock prior to the Effective Date was
not reflected on LexaLite's stock transfer records, the transferee may be
required, as a condition to exchange, to present the certificate representing
such shares together with all documents required to evidence and effect such
transfer and payment of applicable transfer taxes or evidence that any
applicable stock transfer taxes have been paid.


                           TREATMENT OF STOCK OPTIONS
    
  As of the close of business on October 14, 1996 there were an aggregate of
104,550 of LexaLite's Common Stock reserved for issuance upon the exercise of
outstanding stock options, at a weighted average exercise price of $8.13 per
share.  See "Information Concerning LexaLite - Management - Stock Options."
Pursuant to the provisions of the Reorganization Agreement, upon consummation of
the Merger each of these options will be exchanged on the Effective Date for
options to purchase one and one-half (1.5) shares of Summa's Common Stock,
subject to possible upward adjustment, for each share of LexaLite's Common Stock
subject thereto, at the same aggregate price.  Consequently, immediately
following consummation of the Merger, former option holders of LexaLite will
hold, in the aggregate, options to purchase a total of 156,825 shares of Summa's
Common Stock, subject to possible upward adjustment.     
    
  As of the close of business on October 14, 1996, there were 237,473 shares of
Summa's Common Stock reserved for issuance upon the exercise of outstanding
stock options, at a weighted average exercise price of $4.05 share.  Each of
these options will continue to be outstanding following the Merger on the terms
and conditions as in effect immediately prior thereto without modification.  An
additional 187,527 shares are reserved for issuance upon exercise of stock
options that may be granted under the Summa existing stock option plans.  See
"Information Concerning Summa - Management - Stock Options."     

    
                                FAIRNESS OPINION     
    
  Among other conditions to the respective obligations of LexaLite and Summa to
consummate the Merger, the Reorganization Agreement specifies that an investment
banking firm mutually acceptable to Summa and LexaLite shall have rendered an
opinion, prior to the date on which this Joint Proxy Statement/Prospectus is
first mailed, which is not subsequently withdrawn, addressed to the Boards of
Directors of both LexaLite and Summa, to the effect that the terms and
conditions upon which the Merger is to be consummated pursuant to the
Reorganization Agreement are fair from a financial point of view to both the
stockholders of LexaLite and the shareholders of Summa.  After representatives
of both LexaLite and Summa had jointly interviewed a number of independent
investment banking firms, the parties mutually engaged the investment banking
firm of Wedbush Morgan Securities ("Wedbush Morgan") to render the "fairness"
opinion specified by the Reorganization Agreement.  Wedbush Morgan was not asked
to recommend the amount of consideration to be paid to the stockholders of
LexaLite as a consequence of the Merger, which was determined through      

                                       22
<PAGE>
 
    
arms length negotiations between Summa and LexaLite, and Wedbush Morgan did not
participate in such negotiations. Rather, Wedbush Morgan was asked to render an
opinion as to whether the consideration agreed upon by the parties was fair from
a financial point of view to both the stockholders of LexaLite and the
shareholders of Summa, with no restrictions or limitations being imposed on
Wedbush Morgan with respect to their procedures or investigations of Summa or
LexaLite. On October 11, 1996, Wedbush Morgan delivered its written opinion to
the Boards of Directors of LexaLite and Summa to the effect that the terms and
conditions of the proposed Merger are fair from a financial point of view to the
stockholders of LexaLite and the shareholders of Summa. In arriving at its
opinion, Wedbush Morgan reviewed relevant documents, visited the facilities of,
and interviewed the managements of both Summa and LexaLite and performed
extensive financial analyses of Summa and LexaLite. These analyses included the
study of the valuation of public market comparable companies, the review of the
valuation of comparable merger and acquisition transactions, and the analysis of
the relevant contribution of key financial performance criteria by Summa and
LexaLite to the consolidated enterprise. Wedbush Morgan also took note of the
fact that KVP Systems, Inc., a wholly-owned subsidiary of Summa, and Summa, are
respondents and counter-claimants in a patent infringement lawsuit. Their
opinion is based on the assumption that the outcome of such legal proceedings
would not have a material adverse effect on the financial position of Summa. The
full text of the written opinion of Wedbush Morgan, which sets forth the
assumptions made and the factors considered by Wedbush Morgan in rendering its
opinion, as well as the limitations on the review undertaken in connection
therewith, is set forth as Appendix II to this Joint Proxy Statement/Prospectus
and should be read in its entirety. The opinion of Wedbush Morgan is addressed
only to the Boards of Directors of LexaLite and Summa and is intended to be for
the benefit of such Boards of Directors, not for the benefit of stockholders or
shareholders or any other third parties. The opinion of Wedbush Morgan does not
constitute a recommendation by Wedbush Morgan to any stockholder of LexaLite or
shareholder of Summa as to how to vote on the proposed Merger.    

                      ADDITIONAL CONDITIONS TO THE MERGER

  As set forth in the Reorganization Agreement, the obligations of Summa and
LexaLite to consummate the Merger are subject to a number of additional
conditions, including, among others: (1) the Registration Statement of which
this Joint Proxy Statement/Prospectus is a part shall have been declared
effective by the Commission, thereby registering the shares of Summa's Common
Stock issuable to the stockholders of LexaLite as a consequence of the Merger
under the Securities Act; (2) the Merger shall have been approved by holders of
at least a majority of the shares of LexaLite's Common Stock outstanding on the
record date for the LexaLite Special Meeting; (3) the Merger shall have been
approved by holders of at least a majority of the shares of Summa's Common Stock
outstanding on the record date for the Summa Annual Meeting; (4) the holders of
not more than 2% of LexaLite's Common Stock shall have become "perfected
dissenting stockholders" pursuant to the provisions of the Delaware General
Corporate Law; (5) all former LexaLite Stockholders who will become "affiliates"
of Summa as a consequence of the merger (as such term is defined in Rule 145
under the Securities Act) shall have entered into an agreement restricting their
ability to engage in resales or transfers of Summa's Common Stock following the
Merger; (6) all approvals and authorizations of all governmental authorities
required for the consummation of the Merger, and for the issuance of the shares
of Summa's Common Stock issuable as a consequence thereof, shall have been
received; (7) all of the shares of Summa's Common Stock issuable to the
stockholders of LexaLite as a consequence of the Merger shall have been listed
for trading on The Nasdaq National Market; and (8) all representations and
warranties made by each party to the other in the Reorganization Agreement shall
continue to be accurate in all material respects, and there shall have been no
material adverse change in the business or financial condition of either party.

  At any time before or after the approval of the Merger by the shareholders of
Summa and the stockholders of LexaLite, the Board of Directors of either Summa
or LexaLite may, without shareholder or stockholder approval, waive compliance
with any of the applicable terms or conditions contained in the Reorganization
Agreement, except that the Merger may not be consummated unless at least a
majority of the outstanding shares of both LexaLite's Common Stock and Summa's
Common Stock are voted in favor of the Merger.

                                       23
<PAGE>
 
                            AMENDMENT OR TERMINATION
    
  Both the Reorganization Agreement and the Merger Agreement may be amended by
written agreement between the parties either before or after the approval of the
Merger by the stockholders of LexaLite and the shareholders of Summa, provided
that after such approval no such amendment may be made that will change the
amount or kind of consideration to be received by the LexaLite stockholders as a
consequence of the Merger, alter in any manner the Certificate of Incorporation
of LexaLite, or, in the judgment of the LexaLite Board of Directors or the Summa
Board of Directors, as the case may be, otherwise materially and adversely
affect the respective rights of the LexaLite stockholders or the Summa
shareholders.     

  The Reorganization Agreement and the Merger Agreement may each be terminated
at any time before or after approval by the shareholders of Summa and the
stockholders of LexaLite, by mutual agreement of the Boards of Directors of
LexaLite and Summa, or by the Board of Directors of either party if the Merger
has not been consummated by January 31, 1997, except that the foregoing right to
terminate is not available to a party whose failure to perform any covenant or
condition within that party's control is the proximate cause of the failure of
the Merger to be consummated by that date.  In addition, the Reorganization
Agreement and the transactions contemplated thereby may be terminated by either
LexaLite or Summa in the event that the Board of Directors of either has
determined that consummation of the Merger could reasonably be expected to cause
the directors of the terminating party to violate their fiduciary duties under
applicable law.  Any termination as described in the preceding sentence would be
conditioned upon payment by the terminating party to the other of the sum of
$500,000, as liquidated damages in respect of the loss of the non-terminating
party's prospective economic opportunity, plus reimbursement of all out-of-
pocket expenses reasonably incurred by the non-terminating party through the
date of such termination.


                              STANDSTILL AGREEMENT

  In the Reorganization Agreement, LexaLite and Summa have agreed that before
the effective time of the Merger, unless the Reorganization Agreement is sooner
terminated, neither of them will entertain, negotiate or discuss with any third
party, directly or indirectly, any business combination, sale of assets or stock
or other transaction that would be inconsistent with the transactions
contemplated by the Reorganization Agreement, including the Merger.  In
addition, LexaLite and Summa have agreed that if either of them terminates the
Reorganization Agreement, then for the following three years neither of them
may, without the written consent of the Board of Directors of the other party,
acquire, seek, propose or agree to acquire, or cause to be acquired the assets,
business or voting securities of the other party or any rights or options to
acquire such ownership, seek or propose to influence or control the management
or policies of the other party, or enter into negotiations, discussions,
arrangements or understandings with any third party with respect to the
foregoing.


                   INTERESTS OF CERTAIN PERSONS IN THE MERGER
    
  Pursuant to the Reorganization Agreement, and as a condition to the
obligations of the parties to consummate the transactions contemplated thereby,
Josh T. Barnes, who is the founder, Chief Executive Officer and a director of
LexaLite, shall have agreed to continue his employment by LexaLite for an
indeterminate period of time following the Merger, on the same terms and
conditions (except that Mr. Barnes will serve as Executive Director rather than
Chief Executive Officer of LexaLite), including compensation and benefit levels,
in effect immediately prior to the Merger.  For a description of the terms and
conditions upon which Mr. Barnes is currently employed by LexaLite, see
"Management of LexaLite - Employment Arrangement."  The Design and Consulting
Agreement between LexaLite and Business Activities Corporation, which is owned
by Mr. Barnes, will continue in force following the Merger.  In addition, the
existing Non-Compete Agreement between LexaLite and Mr. Barnes will be revised,
effective upon consummation of the  Merger, to provide for the payment to Mr.
Barnes of $15,000 per quarter for 20 consecutive quarters from and after the
date on which the Non-Compete Agreement becomes effective.  See "Information
Concerning LexaLite -Management of LexaLite - Certain Transactions."     

  The Reorganization Agreement provides that, as a condition of LexaLite's
obligation to consummate the Merger, Josh T. Barnes must have been elected to
the Board of Directors of Summa, effective as of the Effective Date of the
Merger, to serve in that capacity until changed in accordance with applicable
law and the Articles of Incorporation and Bylaws of Summa.  Mr. Barnes will
receive no additional compensation for his services as a director.

                                       24
<PAGE>
 
  The Reorganization Agreement further provides that, after the Merger, Mr.
Barnes and Thomas M. Phillips, President and a director of LexaLite, will
continue as directors of LexaLite, along with Mr. Swartwout, until changed in
accordance with applicable law and the Certificate of Incorporation and Bylaws
of LexaLite.  For a description of arrangements between LexaLite and certain of
the executive officers and directors of LexaLite that will survive the Merger,
see "Information Concerning LexaLite - Management of LexaLite - Certain
Transactions."
    
  In connection with the Merger, the holders of all outstanding options to
purchase shares of LexaLite's Common Stock will surrender their options for
cancellation, in consideration of the grant by Summa of options to purchase one
and one-half (1.5) shares of Summa's Common Stock, subject to possible upward
adjustment, for each share of LexaLite's Common Stock subject to their
outstanding LexaLite options, at the same aggregate exercise prices.  See
"Description of the Merger - Treatment of Stock Options and Stock Awards."  Of
the outstanding options to purchase LexaLite's Common Stock, Josh T. Barnes
holds options to purchase 18,500 shares.  See "Information Concerning LexaLite -
Management - Stock Options."     


           AFFILIATES' RESTRICTIONS ON RESALE OF SUMMA'S COMMON STOCK
    
  The shares of Summa's Common Stock to be issued in the Merger will be
registered under the Securities Act, pursuant to the Registration Statement on
Form S-4 of which this Joint Proxy Statement/Prospectus is a part, thereby
allowing such securities to be traded without restriction by all former holders
of LexaLite's Common Stock who do not become "affiliates" of Summa as a
consequence of the Merger, as such term is defined for purposes of Rule 145
under the Securities Act.  As a condition to the Merger, Josh T. Barnes, who
will join the Board of Directors of Summa and will acquire approximately 6.5% of
Summa's Common Stock outstanding immediately following the Merger, will be
required to execute an "affiliate agreement" pursuant to which he will agree not
to publicly sell or otherwise dispose of any of Summa's Common Stock received in
the Merger except in transactions permitted by the resale provisions of Rule
144.     

                              ACCOUNTING TREATMENT

  The Merger will be accounted for as a "purchase" by Summa of the net assets of
LexaLite in accordance with generally accepted accounting principles.
Accordingly, the purchase price will be allocated to the assets and liabilities
acquired based on fair values, and the results of LexaLite's operations will be
included in the consolidated results of operations of Summa only from and after
the Effective Date of the Merger.


                        MERGER EXPENSES; BROKERAGE FEES
    
  Each party will pay all of its own expenses incurred incident to the
preparation and carrying out of the transactions contemplated by the
Reorganization Agreement.  Summa estimates that the expenses it will incur in
connection with the Merger, including effecting compliance with federal and
state securities law registrations, other filings, legal, accounting, exchange
agent, printing, mailing and other costs, fees and expenses, will aggregate
approximately $100,000.  LexaLite estimates that the expenses which it will
incur in connection with the Merger for legal, accounting and other fees and
expenses will aggregate approximately $400,000.     

  In addition to the foregoing expenses, upon consummation of the Merger Summa
and LexaLite have agreed to issue an aggregate of 30,000 shares of Summa's
Common Stock to Synergy, Inc., and pay Synergy, Inc. $42,000 in cash, in
satisfaction of any and all claims that Synergy, Inc. might have against Summa
and LexaLite in respect of brokerage or finder's fees in connection with the
Merger.


                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

  Set forth below is a summary of certain federal income tax consequences of the
Merger to LexaLite stockholders under the Internal Revenue Code of 1986, as
amended (the "Code").  The discussion does not deal with all the tax
consequences of the Merger that may be relevant to particular LexaLite
stockholders, such as dealers in securities, foreign persons or certain persons
who acquired LexaLite stock (or options to acquire stock) as consideration for
the performance of services.

                                       25
<PAGE>
 
  Based upon certain assumptions, it is expected that the Merger will qualify as
a "reorganization" within the meaning of Section 368(a)(1)(A) of the Code, and
that accordingly:

  (a) No gain or loss will be recognized for federal income tax purposes by
stockholders of LexaLite upon their receipt of shares of Summa's Common Stock in
exchange for their LexaLite Common Stock;

  (b) Each former LexaLite stockholder's aggregate adjusted basis in the shares
of LexaLite's Common Stock exchanged in the Merger will be carried over to the
shares of Summa's Common Stock received in the Merger;

  (c) The holding period for the shares of Summa's Common Stock received in the
Merger is expected to include the holding period for LexaLite's Common Stock
exchanged therefor, provided LexaLite's Common Stock is held as a capital asset
as of the Effective Date;

  (d) Upon the subsequent sale of each share of Summa's Common Stock received by
former LexaLite stockholders in the Merger, gain or loss will be recognized.
Such gain or loss will be measured by the difference between the amount received
therefor and the adjusted basis of such share.  If such share is a capital asset
in the hands of the selling stockholder, such gain or loss will be capital gain
or loss which will be long term or short term depending upon the holding period;
and

  (e) Cash received by a LexaLite stockholder who exercises his or her
dissenters' appraisal rights, or in lieu of fractional shares, will generally be
taxable as capital gain or loss, depending upon the stockholder's basis in the
shares and assuming that such shares are capital assets in his hands.

  BECAUSE OF THE UNCERTAINTY OF SEVERAL OF THE TAX CONSEQUENCES OF THE MERGER,
IT IS STRONGLY URGED THAT ALL LEXALITE STOCKHOLDERS CONSULT THEIR OWN TAX
ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING
THE APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX LAWS.


                             APPROVAL OF THE MERGER

  The Boards of Directors of LexaLite, Summa, and Subsidiary have each
unanimously approved the Reorganization Agreement, the related Merger Agreement,
and the transactions contemplated thereby.  In addition, Summa, as the sole
shareholder of Subsidiary, has also previously approved the Merger.  Under
Delaware and California law, the Merger cannot be consummated without the
affirmative vote of the holders of a majority of the outstanding shares of
LexaLite's Common Stock and of Summa's Common Stock in favor of the Merger
Agreement and the transactions contemplated thereby.

  In approving the Merger, the shareholders of Summa will also approve, among
other things, an amendment to the Articles of Incorporation of Summa to
establish a 9-member Board of Directors divided into three classes serving
staggered 3-year terms.  Summa's Board of Directors currently consists of eight
members divided into two classes, with half of the members elected to serve 2-
year terms at each annual meeting of shareholders.  Accordingly, should the
shareholders of Summa approve the Merger, the period of time required for Summa
shareholders who oppose the policies of Summa's Board of Directors to remove a
majority of the Board will be extended from two to three years, unless they can
show cause and obtain the required vote under California law.
    
  Each of the executive officers and directors of LexaLite has indicated his
intention to vote or cause to be voted all of the shares of LexaLite's Common
Stock owned by him, or over which he has voting control, in favor of the Merger.
As of the record date for the LexaLite Special Meeting, these individuals owned
or had voting control over an aggregate of 676,007 shares, or approximately
48.9% of the outstanding shares of LexaLite's Common Stock.  Accordingly,
approval of the Merger by the stockholders of LexaLite will require the
affirmation vote of the holders of an additional  15,562 shares of LexaLite's
Common Stock.     

                                       26
<PAGE>
 
    
  Executive officers and directors of Summa who, as of the record date for the
Summa Annual Meeting, together owned or had voting control over an aggregate of
247,356 shares of Summa's Common Stock, or approximately 15.4% of the shares
outstanding, have indicated their intention to vote or cause to be voted all of
the shares of Summa's Common Stock owned by them, or over which they have voting
control, in favor of the Merger.    The affirmative vote of an additional
554,386 shares of Summa's Common Stock will therefor be required for the
approval of the Merger by the shareholders of Summa.     


                   RIGHTS OF DISSENTING LEXALITE STOCKHOLDERS

  If the Merger is consummated, holders of LexaLite's Common Stock, in respect
of which appraisal rights have been perfected and not withdrawn or lost, will be
entitled to have the "fair value" of their shares of LexaLite's Common Stock at
the Effective Date (exclusive of any element of value arising from the
accomplishment or expectation of the Merger) judicially determined and paid to
them by complying with the provisions of Section 262 of the Delaware General
Corporation Law.  The following is a brief summary of Section 262 which sets
forth the procedures for dissenting from the Merger and demanding statutory
appraisal rights.  This summary is qualified in its entirety by reference to
Section 262, the text of which is attached hereto as Appendix III.  Appendix III
should be reviewed carefully by any holder who wishes to exercise statutory
appraisal rights or who wishes to preserve the right to do so because failure to
comply with the procedures set forth in Section 262 will result in the loss of
appraisal rights.

  Holders of LexaLite's Common Stock of record who desire to exercise their
appraisal rights must satisfy all of the following conditions.  A written demand
for appraisal of shares of LexaLite's Common Stock must be filed with LexaLite
before the taking of the vote on the proposal to approve and adopt the Merger
Agreement.  Such written demand for appraisal of shares must be in addition to
and separate from any proxy or vote abstaining from voting on or voting against
the proposal to approve and adopt the Merger Agreement.  Voting against,
abstaining from voting on or failing to vote on the proposal to approve and
adopt the Merger Agreement will not constitute a demand for appraisal within the
meaning of Section 262.

  Holders of LexaLite's Common Stock electing to exercise their appraisal rights
under Section 262 must not vote for approval and adoption of the Merger
Agreement.  If a holder of LexaLite's Common Stock returns a signed proxy but
does not specify a vote against approval and adoption of the Merger Agreement or
a direction to abstain from voting on the approval and adoption of the Merger
Agreement, the proxy will be voted for approval and adoption of the Merger
Agreement, which will have the effect of waiving such holder's appraisal rights.

  A demand for appraisal must be executed by or for the stockholders of record,
fully and correctly, as such stockholder's name appears on the certificate
representing such stockholder's shares of LexaLite's Common Stock.

  A stockholder who elects to exercise appraisal rights should mail or deliver
his written demand to LexaLite International Corporation, 10163 US 31 North,
Charlevoix, Michigan 49720-0498, Attention:  Secretary.  A written demand may
also be delivered to Secretary at the LexaLite Special Meeting prior to the vote
on the Merger Agreement.  The written demand for appraisal should comply with
the preceding paragraphs, and should specify the stockholder's name and mailing
address and the number of shares of LexaLite's Common Stock owned by such
stockholder and should state that the holder is thereby demanding appraisal of
his shares.  It is the responsibility of each stockholder electing appraisal
rights to ensure that the written demand is received by LexaLite before the
taking of the vote on the Reorganization Agreement and Merger Agreement at the
LexaLite Special Meeting.  Within ten days after the Effective Date, LexaLite,
as the surviving corporation, must provide notice of the Effective Date to all
holders of LexaLite's Common Stock who timely complied with Section 262 and did
not either vote for, or return a signed proxy which did not specify a vote
against or a direction to abstain from voting on, approval and adoption of the
Merger Agreement.

  A stockholder who makes a written demand for appraisal of shares of LexaLite's
Common Stock must continuously hold such shares through the Effective Date.

                                       27
<PAGE>
 
  Within 120 days after the Effective Date, either LexaLite, as the surviving
corporation, or any stockholder who has complied with the required conditions of
Section 262 may file a petition in a Delaware court demanding a determination of
the fair value of the shares of the dissenting stockholders.  If a petition for
an appraisal is timely filed, after a hearing on such petition, the Delaware
court will determine which stockholders are entitled to appraisal rights and
will appraise the shares of LexaLite's Common Stock owned by such stockholders,
determining the fair value of such shares, exclusive of any element of value
arising from the accomplishment or expectation of the Merger, together with a
fair rate of interest to be paid, if any, upon the amount determined to be the
fair value.  In determining fair value, the court is to take into account all
relevant factors.  The cost of the appraisal proceeding may be determined by the
Delaware court and taxed against the parties as the court deems equitable in the
circumstances.  Upon application of a dissenting stockholder, the court may
order that all or a portion of the expenses incurred by any dissenting
stockholder in connection with the appraisal proceeding, including, without
limitation, reasonable attorneys' fees and the fees and expenses of experts, be
charged pro rata against the value of all shares of LexaLite's Common Stock
entitled to appraisal.  In the absence of such a determination or assessment,
each party bears his own expenses.

  Any stockholder who has duly demanded appraisal in compliance with Section 262
will not, after the Effective Date, be entitled to vote for any purpose the
shares of LexaLite's Common Stock subject to such demand or to receive payment
of dividends or distributions on such shares, except for dividends and
distributions payable to stockholders of record at a date prior to the Effective
Date.

  At any time within 60 days after the Effective Date, any stockholder shall
have the right to withdraw his demand for appraisal and to accept the terms
offered in the Merger; after this period, the stockholder may withdraw his
demand for appraisal only with the consent of LexaLite, as the surviving
corporation.  If no petition for appraisal is filed with the Delaware court
within 120 days after the Effective Date, stockholders' rights to appraisal
shall cease.  Inasmuch as LexaLite, as the surviving corporation, has no
obligation, and does not intend, to file such a petition, any stockholder who
desires such a petition to be filed is advised to file it on a timely basis.
However, no petition timely filed in the Delaware court demanding appraisal
shall be dismissed as to any stockholder without the approval of the Delaware
court, and such approval may be conditioned upon such terms as the Delaware
court deems just.

  Since Summa's Common Stock is traded on The Nasdaq National Market,
shareholders of Summa who object to the Merger may vote against the Merger at
the Summa Annual Meeting but will not be entitled to dissenters' rights if the
Merger is consummated over their objections, unless the holders of five percent
or more of Summa's outstanding Common Stock make appropriate demands under
Chapter 13 of the California General Corporation Law.

                                       28
<PAGE>
 
                             THE COMBINED COMPANIES
    
  Once the Merger is consummated, LexaLite, as the surviving corporation in the
Merger, will continue its business and operations as a wholly-owned operating
subsidiary of Summa.  As stated in the Reorganization Agreement, it is the
intention of the parties that the corporate headquarters of LexaLite remain in
Charlevoix, Michigan, and that LexaLite's corporate name will remain unchanged,
for an indefinite period of time following the Merger.  As a condition to the
respective obligations of the parties to consummate the Merger, Josh T. Barnes
is to be added to the Board of Directors of Summa, and the Board of Directors of
LexaLite immediately following the Merger is to be composed of James R.
Swartwout, the President and Chief Executive Officer of Summa, Thomas M.
Phillips, the President of LexaLite, and Josh T. Barnes, the current Chief
Executive Officer of LexaLite.  See "Description of the Merger - Interests of
Certain Persons in the Merger."      

  As one of three operating subsidiaries of Summa immediately following the
Merger, LexaLite will operate on a semi-autonomous basis in much the same way as
the other two 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.  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 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.

              SUMMA AND LEXALITE PRO FORMA FINANCIAL INFORMATION

                                Summa Industries
        Unaudited Pro Forma Condensed Consolidated Financial Statements


  The accompanying unaudited pro forma condensed consolidated financial
statements reflect the acquisition by Summa of all the issued and outstanding
capital stock of LexaLite as a consequence of the Merger of Subsidiary with and
into LexaLite.  The transaction will be accounted as a purchase by Summa of the
net assets of LexaLite.
    
  The unaudited pro forma condensed consolidated balance sheet is based upon
Summa's historical audited consolidated balance sheet at August 31, 1996 and
LexaLite's historical audited balance sheet as of June 30, 1996, and is
presented as if the transaction had been consummated on August 31, 1996.     

  The unaudited pro forma condensed consolidated statement of income for the
year ended August 31, 1996 gives effect to the merger of Subsidiary and LexaLite
as if the transaction had occurred at September 1, 1995, the beginning of
Summa's fiscal year ended August 31, 1996.  The unaudited pro forma condensed
consolidated income statement combines the audited historical consolidated
results of operations of Summa for the  year ended August 31, 1996 and the
audited historical results of the operations of LexaLite for the year ended June
30, 1996.

  The pro forma adjustments are based upon available information and upon
certain assumptions which the respective management of Summa and LexaLite
believes are reasonable.  However, the unaudited pro forma 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.

differences.

  Shareholder Vote Required for Extraordinary Transactions.  Both California and
  --------------------------------------------------------                      
Delaware generally require that a majority of the stockholders approve major
corporate transactions such as mergers.  However, with certain exceptions,
California law requires that mergers, reorganizations, and similar transactions
be approved by a majority vote of each class of shares outstanding.  Therefore,
if Summa issues shares of its Preferred Stock, the holders of such stock would
vote separately as a class on mergers and other major transactions.  In that
event, such holders, even if not in the majority overall, would be able to
control the outcome of voting.  However, the California statute also provides
that, with certain exceptions and unless otherwise required in the corporation's
articles of incorporation, no class vote of preferred shares is required if
their rights, preferences and privileges will not change in the transaction.
Summa's Articles do not alter this rule.

  Dissenters' and Appraisal Rights.  Under both California and Delaware law, a
  --------------------------------                                            
shareholder of a corporation participating in certain major corporate
transactions, such as a merger, consolidation or sale of all or substantially
all of the assets of a corporation, may, under varying circumstances, be
entitled to dissenters' or appraisal rights pursuant to which he may receive
cash in the amount of the fair market value of his shares in lieu of the
consideration he would otherwise receive in the transaction.  Under Delaware
law, appraisal rights are not available to stockholders whose stock is publicly
held and will be converted in the transaction into stock that is publicly held.
Shareholders of a California corporation that is publicly traded (such as Summa)
generally do not have dissenters' rights unless the holders of at least five
percent of the class claim the right or the corporation or any law restricts the
transfer of such shares.  Even in that event, however, dissenters' rights are
unavailable if the corporation or its shareholders, or both, immediately before
the reorganization or immediately after the reorganization will own more than
five-sixths of the voting equity securities (including convertible securities)
of the surviving corporation or its parent.  With respect to the Merger,
LexaLite stockholders have appraisal rights and Summa shareholders will not,
unless the holders of five percent or more of Summa's outstanding Common Stock
seek to perfect their dissenters' rights.  See "Description of the Proposed
Merger - Rights of Dissenting LexaLite Stockholders."

  Removal of Directors.  Under Delaware law, directors may be removed, with or
  --------------------                                                        
without cause, by the holders of a majority of the shares entitled to vote at an
election of directors.  However, unless the corporation's certificate of
incorporation provides otherwise, if the corporation's board of directors is
classified, directors may be removed only for cause.  LexaLite's Board of
Directors is not classified.  Also, in the case of a corporation having
cumulative voting, if less than the entire board is to be removed, no director
may be removed without cause if the votes cast against his removal would be
sufficient to elect him if then cumulatively voted at an election of the entire
board of directors, or, if there are classes of directors, at any election of
the class of directors of which he is a part.  LexaLite's Certificate of
Incorporation does not provide for cumulative voting.

  Under California law, any director or the entire board of directors may be
removed, with or without cause, upon the vote of a majority of the outstanding
shares entitled to vote.  However, in the case of a corporation, such as Summa,
whose Board of Directors is classified, a director may not be removed if the
number of votes cast against his removal would be sufficient to elect the
director under cumulative voting at an election at which the same total number
of votes were cast (or, if the action is taken by written consent, all shares
entitled to vote were voted) and either the number of directors elected at the
most recent annual meeting, or if greater, the number of directors for whom
removal is being sought, were then being elected.

  Classified Board of Directors.  A classified board is one for which a certain
  -----------------------------                                                
number, but not all, of the directors are elected on a rotating basis each year.
A classified board makes changes in the composition of the board of directors
more difficult, and thus a potential change in control of a corporation more
difficult.  Delaware law permits, but does not require, a classified board of
directors, divided into as many as three classes.  LexaLite's Board of Directors
is not classified.

                                       35
<PAGE>
 
  California law permits a "listed" corporation to divide its Board of Directors
into as many as three classes.  Summa is a "listed" corporation and its Articles
of Incorporation divide its Board into two classes, each of which will serve
two-year terms.  If the Merger is approved by Summa's shareholders and
Consummated, Summa's Articles of Incorporation will be amended to establish a
nine (9) member Board of Directors divided into three classes serving staggered
three-year terms.  See "Description of the Proposed Merger - Approval of the
Merger."

  Ability to Issue Preferred Stock.  Summa is authorized to issue up to
  --------------------------------                                     
5,000,000 shares of Preferred Stock in one or more series, the terms of which
may be determined at the time of issuance by its Board of Directors, without
further action by the shareholders, and may include voting rights, preferences
as to dividends and liquidation, conversion and redemptive rights and sinking
fund provisions.  Although Summa has indicated that it has no present plans to
issue any additional shares of Preferred Stock, the issuance of Preferred Stock
in the future could affect the rights of the holders of Summa's Common Stock and
thereby reduce the value of the Common Stock.  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.  LexaLite has no authorized
classes of capital stock other than the Common Stock.

  Other Differences.  Summa is subject to the information and reporting
  -----------------                                                    
requirements of the Securities Exchange Act of 1934 (the "Exchange Act"), which
requires Summa periodically to provide certain specified information to its
shareholders and to file specified reports with the Securities and Exchange
Commission.  In addition, shares of Summa Common Stock are traded on The Nasdaq
National Market.  LexaLite is not subject to the informational and reporting
requirements of the Exchange Act and no active market for its Common Stock
exists.

                          INFORMATION CONCERNING SUMMA

                                    BUSINESS


General
- -------

    Summa Industries ("Summa") was incorporated in California in 1942.  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 completed the first such acquisition in November 1991
by acquiring all of the outstanding capital stock of GST Industries, Inc., a
California corporation engaged in the manufacture and sale of industrial
firefighting equipment and aerospace components and sub-assemblies.  In fiscal
1992, Summa also formed another wholly-owned subsidiary, Morehouse-COWLES, Inc.,
a California corporation, to which all of the operating assets involved in the
conduct of the chemical process equipment business were contributed.  In July
1993, Summa acquired KVP Systems, Inc., a manufacturer of engineered plastic
conveyer components.  In May 1994, Summa acquired certain assets and operations
of Armenco Engineering which were integrated into those of Morehouse-COWLES.  On
June 17, 1996, Summa completed a sale of all of the issued and outstanding stock
of Morehouse-COWLES, Inc.  Consequently, Summa currently serves as a holding
company whose businesses are conducted primarily through its two wholly-owned
subsidiaries, KVP Systems, Inc. and GST Industries, Inc.
    
     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 telecopier number is (310) 792-7079.     


Products
- --------

     The principal products currently offered by Summa, through its two
operating subsidiaries, include material handling components manufactured by KVP
Systems, Inc., industrial firefighting equipment produced by the Stang division
of GST Industries, Inc. ("GST"), and aerospace assemblies fabricated by GST.

     Material Handling Components. Summa's material handling components business
is conducted by its wholly-owned subsidiary, KVP Systems, Inc., located in
Rancho Cordova, California. Its products are engineered plastic components which
form conveyer belts and chains. The components in KVP's product line, many of
which are patented, are constructed of non-toxic, non-corrosive plastic
materials and are designed to be easily cleaned, meeting FDA-USDA requirements
and specifications. The components 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.  The industrial firefighting business is
conducted by the STANG Industrial Products Division ("Stang") of GST Industries,
Inc., which was acquired by Summa  in November 1991.  Stang 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
Industries, Inc., a wholly-owned subsidiary located in Santa Ana, California,
which was acquired in November 1991.  GST has been in this business of
designing, manufacturing and selling hydraulic actuators and other parts and
sub-assemblies for use in aircraft and similar activities for more than 20
years.

Marketing
- ---------
    
     Ultimate users of KVP components in food processing 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. Products are sold directly and through independent
representatives and distributors, world-wide.    

     The primary markets for the Stang products are the oil, gas and
petrochemical industry, municipalities which use fireboats, the mining industry,
and the municipal waste water treatment market. These products are sold through
independent manufacturers' representatives 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 component operating 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, 1996, the largest customer in the above named segments
accounted for 5% of total company sales, while in fiscal years 1995 and 1994,
sales to a single customer accounted for 7% and 4% of total sales, respectively.
     
    
     Most of the sales of the aerospace assemblies segment are of products 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 Department of Defense. Because the F-16 is a mature program which is being
phased out, Summa faces a possible loss of most of its defense related business
over the next several years. The sales of the aerospace assemblies segment
represent 15%, 15% and 21% of consolidated sales of Summa for 1996, 1995 and
1994, respectively, and the sales to the largest customer for the years ended
August 31, 1996, 1995 and 1994 were 6%, 7% and 10%, respectively.

</TABLE>

Raw materials
- -------------
    
     Summa purchases materials and parts, including pelletized plastic resins,
castings, forgings, steel, valves and controls from various suppliers.  Summa
does not believe that it is dependent upon any single supplier or manufacturer
for any of its present principal requirements for materials or parts, and
experienced no significant difficulty in obtaining such parts and materials
during the fiscal year ended August 31, 1996.  Lead times for special
components, such as custom hydraulic power units, can be as long as four months.
     

Backlog
- -------
    
     On August 31, 1996, Summa's continuing businesses had a backlog of orders,
believed to be firm, in the amount of $2,475,000, as compared to a backlog of
$2,924,000 as of August 31, 1995.  Of the backlog at the end of fiscal 1996,
$280,000 was attributable to orders for material handling components, $487,000
was attributable to orders for firefighting equipment and $1,708,000 was
attributable to orders for aerospace assemblies.  A portion of Summa's August
31, 1996 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 1997.
     
Competitive Conditions
- ----------------------

     Summa faces vigorous competition with respect to each of the products
manufactured by its operating subsidiaries, both from firms which market similar
products nationally and internationally, and in certain geographic areas from
local manufacturers.  Many of these competitors have financial and marketing
resources that are significantly greater than those available to Summa.

     In general, Summa believes that its trade names and reputation are
significant to its competitive position in all segments. With respect to all
segments, Summa believes that price is a significant element of competition.
However, factors such as engineering, performance, availability and reliability
are considered in the purchasing process.

                                       39
<PAGE>
 
Patents, Trademarks and Licenses
- --------------------------------

     Summa has been granted numerous U.S. patents (and related foreign patents)
covering certain of its products.  These patents expire on dates ranging from
present to 2010.  Summa has active patent applications.  The expiration of these
patents is not expected to have a material adverse effect on its business.

     Summa has foreign and domestic trade name and trademark registrations
covering the names and logos which appear on its products. In its opinion, its
trademarks are helpful in enabling it to maintain its present competitive
position.

Legal Proceedings
- -----------------
    
     At August 31, 1996, Summa was a party to two civil lawsuits. In Laitram, et
                                                                     -----------
al. v. KVP Systems, Inc., and counterclaims filed in the U.S. District Court in
- ------------------------
Eastern Louisiana in September 1993. The plaintiffs claim KVP has infringed upon
two patents. The venue has been changed to Federal District Court in Sacramento,
California. Summa contends the claims are invalid, and has filed counterclaims
that Laitram has sued in bad faith and has acted in restraint of free trade. The
case is in the advanced stage of discovery and is expected to be heard in court
during fiscal 1997. Since the case involves a number of complex factual and
legal issues, it is impossible to predict the outcome. Although Summa believes
it has a reasonable expectation of prevailing, because no reserve therefor has
been established, and 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 plaintiff filed an appeal of the dismissal.  The Company has
product liability insurance of $2,000,000 covering the period in which the
incident took place, with no other claims in that policy year.     

Employees
- ---------

     At August 31, 1996, Summa employed 98 persons, including the three
employees of the parent company, 64 employees at KVP, of whom 16 were involved
in sales and marketing, 40 in manufacturing, 8 in general administration, and 29
employees at GST, of whom 4 were involved in sales and marketing, 21 in
manufacturing, and 4 in general administration. None of Summa's employees is
covered by a collective bargaining agreement. Summa considers its relationship
with its employees to be good.

Facilities
- ----------

     Summa leases 28,000 square feet of office and manufacturing space in an
industrial park in Santa Ana, California.  The lease expires in October 1996 and
includes an option to extend one year.  Summa leases 48,000 square feet of
office and manufacturing space in an industrial park in Rancho Cordova,
California.  The lease expires in February 2001.  Summa's material handling
component business, conducted by KVP Systems, Inc., relocated in January 1966 to
this larger facility to provide for expanding operations.  Summa leases
approximately 300 square feet of office space in Torrance, California.  The
lease expires in June 1997.

     Summa believes that in general the facilities are adequate for present and
foreseeable needs and that the expiring leases can be renegotiated or alternate
facilities can be leased on favorable terms, as necessary.

     Summa 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.

Results of Operations
- ---------------------

The following table sets forth certain statements of income information for
continuing operations as a percentage of sales for the three years ended August
31, 1994, 1995 and 1996, 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 of the Morehouse-COWLES industrial process equipment business.

     Sales. For the year ended August 31, 1995, total sales were virtually
 unchanged from the prior fiscal year. A decrease in the sales of Stang (without
 benefit of a large 1994 contract) and a decrease in the shipments of the
 defense business were offset by strong growth in the material handling
 components business of KVP Systems, Inc. KVP's sales growth is attributable to
 growing acceptance of its products and the market for its products, an expanded
 sales organization and new product development.     
    
     For the year ended August 31, 1996, 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.     
    
     Gross Profit. Gross profit decreased both in dollar amount (by $131,000, or
3%,) and as a percentage of sales (by 1%) during the year ended August 31, 1995.
This decrease in the gross profit and gross margin was attributable primarily to
the absence in fiscal 1995 of the higher than normal gross margin on the large
Stang contract realized in fiscal 1994.     
    
     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.    
    
     Selling, General and Administrative Expense.  For the year ended August 31,
1995, selling, general and administrative expense decreased by $143,000, or 4%.
This reduction in net selling, general and administrative expense was the result
of a decrease of $442,000 in the amount of contingent performance payments
accrued for the  former shareholders of GST as a consequence of decreased sales
and profitability of Stang and the GST defense business, along with a decrease
in commissions on the reduced level of Stang sales, partially offset by
increased sales and  marketing costs incurred by KVP in expanding its sales
organization.     

                                       42
<PAGE>
 
   
      Selling, general and administrative expenses for the year ended August 31,
1996 increased by $1,071,000, or 31%, when compared to total operating expenses
for fiscal year 1995, and as a percentage of sales, increased from 34.0% to
35.7%, 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.    
    
     Effective Tax Rate.  The effective income tax rate, which is a composite of
federal and state taxes, decreased from 56.3% for fiscal 1994 to 41.6% in fiscal
1995, primarily as a result of a decrease in non-deductible contingent
performance accruals due the former shareholders of GST.  (See Note 8 in Notes
to Consolidated Financial Statements.)  In fiscal 1996, the effective tax rate
decreased further to 40.3% as there were no non-deductible contingent
consideration accruals.     
    
     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
primarily as a result of decreased backlog in 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 1996 through fiscal 1998.
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.    

Liquidity and Capital Resources
- -------------------------------

     Cash provided by operating activities is Summa's most important source of
liquidity.  However, during the 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 year ended August 31,
1996 was $1,577,000, substantially from continuing operations. The improved cash
flows are primarily attributable to lower growth in inventories, lower payments
of accrued contingent performance payments and lower required tax payments.
Additionally, $608,000, net of fees and cash retained by Morehouse-COWLES, was
received as partial consideration for the sale of Morehouse-COWLES, Inc.     
    
     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. Summa expects to continue to
invest heavily in tooling for new products.     
    
     Summa has a revolving line of credit facility of $2,000,000 with an
expiration date of January 1, 1997. The line of credit is secured by all the
assets of Summa. The outstanding balance bears interest at one-quarter
percentage point above the bank's prime rate. There were no borrowings under the
Company's line of credit at August 31, 1996, a reduction of $938,000 from the
August 31, 1995 amount due.    

     During the fiscal year ended August 31, 1995, working capital of Summa's
continuing operations decreased by $204,000, or 10%, from $2,086,000 at August
31, 1994 to $1,882,000 at August 31, 1995.  This decrease was attributable
primarily to increased utilization of Summa's line of credit to finance the
working capital needs of the discontinued business unit, which more than offset
increases in inventories and accounts receivable associated with higher levels
of sales by KVP Systems, Inc.  By August 31, 1996, Summa's working capital had
increased to $2,975,000, reflecting decreased utilization of the line of credit.
    
    Asset utilization for the fiscal years ended August 31, 1995 and 1996, is
illustrated in the following table:

   At August 31, 1996, 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 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.

   The Company has a strategy of growth by acquisition.  Although there are no
plans to make a specific acquisition for cash, in the event such a plan were
adopted, an alternate source of funds to accomplish the acquisition would have
to be developed.  The Company has 10,000,000 shares of common stock authorized,
of which 1,603,483 shares were outstanding at August 31, 1996 and 5,000,000
shares of "blank check" preferred stock authorized of which none is outstanding.
The Company could issue additional shares of common or preferred stock to raise
funds.

Pending Accounting Pronouncements
- ---------------------------------

   In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 121 "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."  SFAS No. 121
requires that long-lived assets and certain identifiable intangibles to be held
and used be reviewed for impairment whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable based on
the estimated future cash flows (undiscounted and without interest charges).
SFAS No. 121 also requires that long-lived assets and certain identifiable
intangibles to be disposed of be reported at the lower of carrying amount or
fair value less costs to sell.  Summa plans to adopt SFAS No. 121 as of
September 1, 1996 and believes the effect of adoption will not be material to
the financial statements.

   In October 1995, the Financial Accounting Standards Board issued SFAS No. 123
"Accounting for Stock-Based Compensation."  Under SFAS No. 123, companies have
the option to implement a fair value-based accounting method or continue to
account for employee stock options and stock purchase plans using the intrinsic
value-based method of accounting as prescribed by Accounting Principles Board
(APB) Opinion No. 25 "Accounting for Stock Issued to Employees."  Entities
electing to remain under APB Opinion No. 25 must make pro forma disclosures of
net income or loss and earnings per share as if the fair value-based method of
accounting defined in SFAS No. 123 had been applied.  SFAS No. 123 is effective
for financial statements for fiscal years beginning after December 15, 1995.
The Company has tentatively determined it will continue to account for stock
options under APB Opinion No. 25.
         
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 investors'
bank credit agreement, permits optional prepayments, contains certain covenants
and default provisions and remedies, is secured by a pledge of all of the
outstanding capital stock of Morehouse-COWLES purchased by the investors, as
well as by the assets 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" will be $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.

Employment Agreement.
- -------------------- 

  In March, 1994, the Company entered into an employment agreement with James R.
Swartwout under which he is to be paid an annual base salary to be determined by
the Board of Directors, and an annual bonus of up to 40% of his base salary, to
be determined by the Board of Directors based upon the performance of Summa
during the preceding fiscal year, payable in cash or stock at his election.  In
the event of his termination, other than for cause, Mr. Swartwout is entitled to
severance pay equal to six months of his current compensations.  In the event of
a "change in control" of Summa (defined as the acquisition by a person or group
of either 30% or more of Summa's voting power or the right to elect a majority
of the directors of Summa, the sale of 50% or more of the total fair market
value of the Company's assets, or a specified change in the composition of
Summa's Board of Directors), and regardless of whether his employment is
terminated as a result of such event, Mr. Swartwout would be entitled to receive
as a special bonus an amount equal to two year's base salary at the level then
being paid to him.  Mr. Swartwout has stated that such a special bonus will not
be payable to him as a consequence of the Merger.


401(k) Plans
- ------------
    
  Summa has adopted Section 401(k) Plans benefitting substantially all employees
in compliance with relevant ERISA regulations.  The plans allow employees to
defer specified percentages of their compensation, as defined, in a tax-exempt
trust.  The Company is required to make matching contributions, as defined, to
the plan and may make additional profit-sharing contributions at the discretion
of the Board of Directors.  The total company contribution to all employees'
401(k) accounts in fiscal 1996 was $83,000.     


Stock Options
- -------------

  In 1984, the Board of Directors and shareholders of Summa approved the Summa
Industries 1984 Stock Option Plan (the  "1984 Plan"), under which options to
acquire an aggregate of 25,000 shares of Summa's Common Stock may be granted to
key employees, as determined by the Compensation Committee of the Board of
Directors.  At August 31, 1996, options to acquire 24,625 shares of Common Stock
had been granted, including options to purchase 12,500 shares granted to Mr.
Swartwout.  The price at which the options may be exercised ranges from $1.50 to

Board of Directors.  At August 31, 1996, options to acquire 125,000 shares of
Summa's Common Stock had been granted, including options to purchase 25,000
shares granted to Mr. Swartwout.  Options to acquire 25,000 shares of Summa's
Common Stock remain available for future grant.  The price at which the options
may be exercised ranges from 2.72 to 6.00, the market price of the stock on the
date of grant.  During the fiscal year ended August 31, 1996, options for 21,188
shares became exercisable.  At August 31, 1996 options for 90,497 shares were

options to acquire an aggregate of 250,000 shares of Summa's Common Stock may be
granted to key employees, directors, consultants, vendors, customers and others,
as determined by the Board of Directors.  At August 31, 1996, options to acquire
101,223 shares of Summa's Common Stock have been granted to ten employees and
seven directors.  Options to acquire 148,777 shares of Summa's Common Stock
remain available for future grant.  The price at which options may be exercised
ranges from $3.613 to $5.10.  During the fiscal year ended August 31, 1996,
options for 96,207 shares became exercisable.  At August 31, 1996, options for
96,207 shares were exercisable, but none had been exercised.

  No options were granted to Mr. Swartwout under the 1984 Plan, the 1991 Plan or
the 1995 Plan during the fiscal year ended August 31, 1996.

Limitation of Directors' and Officers' Liability and Indemnification
- --------------------------------------------------------------------

     Summa's Bylaws provide that Summa must indemnify its officers and
directors, and may indemnify its employees and other agents, to the fullest
extent permitted by California law.  California law provides that directors of a
California corporation will not be personally liable for monetary damages for
breach of fiduciary duties as directors except for liability as a result of
their duty of loyalty to the corporation for acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of law, unlawful
payments of dividends or stock transactions, unauthorized distributions of
assets, loans of corporate assets to an officer or director, unauthorized
purchase of shares, commencing business before obtaining minimum capital, or any
transaction from which a director derived an improper benefit.  Such limitations
do not affect the availability of equitable remedies such as injunctive relief
or rescission.  At present, there is no pending litigation or proceeding
involving any director, officer, employee, or agent of the Company where
indemnification will be required or permitted.  Insofar as indemnification for
liabilities arising under the Securities Act may be permitted to officers,
directors or persons controlling Summa pursuant to the foregoing provisions,
Summa has been informed that, in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Securities Act and is therefore unenforceable.


COMPENSATION COMMITTEE REPORT

Report on Annual Compensation of Executive Officers
- ---------------------------------------------------

     It is the policy of the Company's Compensation Committee to establish
compensation levels for the executive officers, which reflect the Company's
overall performance and their performance, responsibilities and contributions to
the long-term growth and profitability of the Company.  The committee determines
compensation based on its evaluation of the Company's overall performance,
including various quantitative factors, primarily the Company's financial
performance, sales and earnings against the Company's operating plan, as well as
various qualitative factors such as new product development, the Company's
product and service quality, the extent to which the executive officers have
contributed to forming a strong management team and other factors which the
committee believes are indicative of the Company's ongoing ability to achieve
its long-term growth and profit objectives.

                                       48
<PAGE>
 
     The principal component of the compensation of the executive officers is
their base salaries.  The committee also retains the discretion to award bonuses
based on corporate or individual performance.  The committee evaluates the
practices of various industry groups, market data, including data obtained from
time to time from outside compensation consultants, and other economic
information to determine the appropriate ranges of base salary levels which will
enable the Company to retain and incentivize the executive officers.  Throughout
the year, the committee members review the corporate and individual performance
factors described above.  The committee, based upon its review of performance
for the previous year and its review of the Company's operating plan,
establishes salary levels and awards any bonuses to the executive officers.

     The Compensation Committee also considers grants of stock options for the
Company's key employees, including executive officers.  The purpose of the stock
option program is to provide incentives to the Company's management to work to
maximize shareholder value.  The option program also utilizes vesting periods to
encourage key employees to continue in the employ of the Company.  Individual
amounts of annual stock option grants are derived based upon review of
competitive compensation practices with respect to the same or similar executive
positions, overall corporate performance and individual performance.

                        INFORMATION CONCERNING LEXALITE

                                    BUSINESS

General
- -------

     LexaLite International Corporation was incorporated in Michigan in 1963 and
subsequently reincorporated in Delaware.  LexaLite designs, manufactures and
markets plastic optical components (refractors and reflectors), and other molded
plastic products.

     The principal executive office of LexaLite is located at 10163 US 31 North,
Charlevoix, Michigan 49720-0498, and its telephone number is (616) 547-6584.

Products
- --------

     The original products of LexaLite 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 the products made by LexaLite over more
traditional glass or metal components are lighter weight, superior optical
performance and in certain instances, lower cost.  The design of optical
components is very specialized, and LexaLite has developed an elite capability
in this field.  Additionally, LexaLite has an excellent tool manufacturing
department which is necessary because tooling for injection molding is complex
and must be manufactured to close tolerances.

Research and Development
- ------------------------

     LexaLite has consistently invested heavily in research and development of
products and manufacturing methods.  For the years ended June 30, 1994, 1995 and
1996, LexaLite spent $554,000, $671,000 and $885,000, respectively, on research
and development.  This activity is conducted at two facilities, located and
staffed separately from the corporate headquarters:

     Lighting Research Center ("LRC").  The staff at LRC designs optical
surfaces using computer aided design techniques.  Prototypes of products are
fabricated and photometric performance testing is conducted in one of the best
equipped lighting test facilities in the world.

     LexaLite Scientific Center ("LSC").  This facility was created in 1994 to
develop confidential products and methods.  Currently, LexaLite is developing
components for an innovative high-performance flat-screen display under contract
to a unit of AlliedSignal.  LexaLite is also developing an automated vapor-
deposition coating process for its own use, which is expected to materially
reduce the cost and increase the photometric performance of development plastic
"canister" components to be used in recessed lighting fixtures.  If successful,
this product could result in a significant increase in LexaLite sales because
these components are generally made of metal by others.

     Injection molds or tools are made by a LexaLite division known as
Charlevoix Tool and Engineering ("CTE") which both contracts outside and has
expert toolmakers on staff.  CTE is located at the main plant in Charlevoix,
Michigan.

Manufacturing
- -------------

     LexaLite has developed elite injection molding capability. 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 registered to ISO 9002.

                                       50
<PAGE>
 
Marketing
- ---------

     The majority of LexaLite's sales are to OEM lighting fixture manufacturers.
LexaLite seeks to maintain a "strategic partnership" relationship with its
customers and has a direct sales force of seven persons who operate out of two
manufacturing plants in Michigan and Tennessee.  Additionally, LexaLite sells
some product through commissioned sales representatives in selected geographic
areas and business situations, including international.

     For the year ended June 30, 1996, 91% of sales were made directly and 9% of
sales were through commercial manufacturers' representatives.  LexaLite
differentiates between product sales and sales of tooling.  Of product sales for
June 30, 1996, 50.4% of sales were of products made from LexaLite proprietary
tooling, 31.5% were of optical components manufactured for a single customer
using tooling owned by others, and 14.6% of product sales were of non-optical
components.  Sales of all optical components are considered strategic.  The non-
optical products are manufactured to expand the business relationship with
customers for strategic products or to balance the utilization of manufacturing
capacity.

     LexaLite products are installed in high-bay manufacturing plants,
warehouses, retail stores, gasoline stations, parking lots, and other types of
buildings, in traffic signals, marine navigation aids and vehicles.  Because the
products are components, they are virtually always sold to OEM manufacturers.
These include major industrial companies such as Hubbell, Lithonia division of
National Service Industries, Inc., Cooper, Thomas Industries, and GE as well as
many less well recognized companies.  For the year ended June 30, 1996, LexaLite
had 322 active accounts.  Sales to the largest five customers were 15.4%, 12.8%,
9.6%, 8.5% and 3.6% of product and tooling sales, respectively.  Product sales
comprise 92.6% of total net sales.  These customers have all been active
accounts for more than ten years.  Sales outside the United States were 8.2% of
total sales.

     Sales are somewhat related to commercial building construction but are
generally not seasonal.

Raw Materials
- -------------

     LexaLite 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.

Backlog
- -------

     Since LexaLite's lead time for producing components is only two to four
weeks, backlog is usually minimal and typically represents approximately one and
one-half (1.5) months of product sales.  The backlog of orders for tooling, as
opposed to products, the lead time for which is four to ten months, varies
widely.  At June 30, 1996, the backlog of firm orders for new tooling was
$804,000, approximately six months of planned tooling sales.  Tooling sales
typically are about 3.5% of product sales.

Competitive Conditions
- ----------------------

     A significant number of custom injection molders, some of which are larger
than LexaLite, 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.

Patents, Trademarks and Licenses
- --------------------------------

     LexaLite has numerous domestic and foreign patents, some of which are
believed by management to protect commercial products from imitative
competition.

                                       51
<PAGE>
 
     LexaLite develops many products independently for sale to multiple
customers.  Products are also developed jointly with specific instructions under
various arrangements which could include exclusivity, a license to LexaLite to
make sales to third parties or other special agreements.  The consultative
nature of these development efforts is part of the strategic value-added nature
of LexaLite's business and the confidentiality of these activities is ardently
maintained.

Compliance with Environmental Regulations
- -----------------------------------------

     LexaLite monitors environmental compliance via a full-time environmental
engineer, reporting directly to a vice-president.  LexaLite believes that it is
in compliance with all requirements set forth by the E.P.A. and the states of
Michigan and Tennessee relating to air quality, water quality and hazardous
waste management and disposal.

Legal Proceedings
- -----------------

     LexaLite was not a party to any material pending or threatened litigation
at June 30, 1996.

Employees
- ---------

     At June 30, 1996, LexaLite had approximately 100 salaried and 168 hourly
employees, none of whom is represented by a labor union.  LexaLite considers its
relationship with its employees to be excellent.  The headquarters is located in
a small town in Northwest Michigan with a limited labor pool, and 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 does not currently consider a labor surplus to exist there.

Facilities
- ----------

     LexaLite owns four separate facilities.  The original plant and corporate
headquarters which has been expanded several times over the years, 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 LexaLite Research Center
comprises 14,700 square feet of office, testing and light manufacturing area on
three-quarters of an acre of land in Charlevoix, Michigan.  The LexaLite
Scientific Center comprises 27,500 square feet of office and manufacturing area
on 11 acres of land in a business park in Charlevoix, Michigan.  The facility
was constructed with utilities in place so that it can be modularly expanded as
required.  The Tennessee plant comprises 55,000 square feet of office and
manufacturing area on 24 acres of land in Dickson, Tennessee.  Substantially all
of LexaLite's properties are pledged to secure debt.  The LexaLite Scientific
Center was built with the proceeds of a Michigan Industrial Revenue Bond.

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

Results of Operations
- ---------------------

          Net Sales.  For the fiscal year ended June 30, 1996, net sales
increased approximately 8.6%.  A reduction in sales to one customer of non-
optical components of $463,000 was more than offset by increases in sales of
proprietary lighting products and revenues from design and development services.
Sales of the proprietary "800 Series" products, large scale refractors for high-
bay lighting fixtures, increased $2.4 million or 36% during 1996.  Revenues from
design and development services increased $425,000 or 94% in 1996.

          In 1995, net sales increased approximately 24.1%.  Sales to the
lighting industry as well as sales of consulting and development services,
accounted for the increase.  Sales of the "800 Series" products increased $2.4
million or 52% in 1995.

          Gross Margin.  Gross margin as a percent of sales was 25.3%, 23.8% and
24.9% in the respective years.  The modest decline in 1995 margins versus 1994
reflects increased resin prices that could not be immediately passed on to
customers offset partially by the favorable impact of higher volumes on overhead
allocation.  The slight improvement in 1996 reflects the favorable impact of
increased revenues in the higher margin proprietary products and service lines
mentioned above.
    
          Operating Expenses.  As a percentage of sales, selling, general and
administrative expenses remained relatively stable at 13.9%, 13.6% and 14.3% in
1996, 1995 and 1994, respectively.  The decline in selling, general and
administrative expenses as a percentage of sales in 1995 reflects LexaLite's
increased sales which outpaced increases in operating expenses in that 
year.     

          Research and development costs were 2.5%, 2.0% and 2.1% of sales in
1996, 1995, and 1994, respectively.  The increase in 1996 is attributable to
LexaLite's investment in LexaLite Scientific Center which was opened in the
beginning of 1996.
    
          Interest Expense.  In 1996, interest expense was $721,000, an increase
of $158,000 from 1995, reflecting an increase in debt assumed to expand the
LexaLite Scientific Center.  Approximately $185,000 of interest costs were
capitalized in 1995 during the construction of the facility.  Approximately 53%
of the debt is comprised of Michigan Industrial Revenue Bonds which bear an
average interest rate of approximately 6%, substantially below commercial
lending rates.     

          Income Taxes.  The effective tax rates were 37.7%, 36.1% and 34.8% in
1996, 1995, and 1994, respectively.  The variance from the federal statutory
rate is primarily due to the effect of state income taxes.

          Net Income.  In 1996, LexaLite reported net income of $1,588,000 or
4.4% of sales versus $1,422,000 or 4.3% of sales in 1995, and $1,183,000 or 4.4%
of sales in 1994.  Improvements in net income are primarily volume related.

Liquidity and Capital Resources.
- --------------------------------
    
          During 1996, working capital increased $539,000, or 18%.  The current
ratio remained constant at 1.6 and the quick ratio remained at 1.2 for 1996 and
1995.     

          LexaLite's most important sources of liquidity are cash provided by
operating activities and credit arrangements with a bank.  Cash flow from
operations has been $3,327,000 and $2,754,000 during 1996 and 1995,
respectively.  In addition, LexaLite has available credit facilities totaling
$4,250,000.  Plans for capital additions of approximately $2,600,000 in 1997 are
anticipated to be financed through cash flows from operations and the existing
credit facilities.

          If LexaLite were to increase its expansion of facilities and its sales
were to continue to grow as they have in the last three years, LexaLite would
approach its debt capacity, in which case an alternate source of funds would
have to be developed.  Management believes the proposed merger with Summa could
provide the opportunity to raise additional equity capital for the future.

Inflation
- ---------

          Over the recent year, LexaLite has experienced pricing pressures on
certain plastic resins.  LexaLite has been relatively successful in negotiating
price contracts with its vendors as well as passing on a portion of the price
increases to its customers.  Management does not expect inflation to have a
significant impact on LexaLite's future gross margins.

Employment Arrangement
- ----------------------
    
    Josh T. Barnes currently serves as Chief Executive Officer of LexaLite on
terms and conditions adopted by LexaLite's Board of Directors as of September
17, 1993.  These resolutions confirm Mr. Barnes as an "at-will" employee of
LexaLite and grant both Mr. Barnes and LexaLite the right to terminate his
employment at any time.  In the resolutions, a salary for Mr. Barnes of $60,000
per year is established, subject to annual review by LexaLite's Board of
Directors, and reimbursement of his necessary costs and expenses, including the
costs of suitable transportation, is authorized.  In addition, the terms under
which Mr. Barnes will be paid incentive annual bonuses are set forth.  LexaLite
is not obligated to provide Mr. Barnes any specific severance compensation in
the event his employment is terminated by either Mr. Barnes or LexaLite, except
that his salary and benefits would continue for six months following
termination.  However, the resolutions state that each party expects that the
manner, notice and terms of termination of Mr. Barnes' employment would
recognize the many years of Mr. Barnes' service to LexaLite.  For a description
of certain modifications to these arrangements which will become effective upon
consummation of the Merger, see "Description of the Proposed Merger - Interests
of Certain Persons in the Merger."  In addition, Mr. Barnes has entered into a
Non-Compete Agreement with LexaLite, which will be triggered by and survive the
termination of his employment with LexaLite.  See "Management of LexaLite -
Certain Transactions."  The Non-Compete Agreement will also be modified in
connection with the Merger.  See "Description of the Proposed Merger - Interests
of Certain Persons in the Merger."     

Stock Award Bonus Plan
- ----------------------

    The Board of Directors of LexaLite has established a Stock Award Bonus Plan,
the purpose of which is to permit grants of shares to key officers of LexaLite,
as a means of retaining and rewarding them for long-term performance and to
increase their ownership in LexaLite.  Shares awarded under the Plan are based
on discretionary percentage of aggregate stock value growth, as defined by the
Plan.  The awards vest in three annual installments and are paid in the form of
stock and cash.  For the fiscal year ended June 30, 1996, an aggregate of 20,893
shares of LexaLite's Common Stock was granted to three key executives including
8,357 shares granted to Mr. Phillips and 6,268 shares granted Ms. DeYoung.  In
July 1996, non-qualified stock options to purchase 54,000 shares of Common Stock
at the price of $9.00 per share were granted to four key executives in
consideration of the termination of the Stock Award Bonus Plan described herein,
including options to purchase 15,000, 15,000, 12,000 and 12,000 shares were
granted to Mr. Barnes, Mr. Phillips, Ms. DeYoung and Ms. Mitter, respectively.
The options will vest over a period of four years provided the key executives
continue to serve as employees or consultants to LexaLite.

Stock Options
- -------------
    
    LexaLite has two existing stock option programs, the intent of which is to
retain and reward key employees for their performance and also to provide a
means for ownership outside the ESOP.  The original plan, a non-qualified stock
option plan, has only one remaining open grant.  In November 1993, the Board
authorized options as of January 1994 to be granted to key employees.  Options
are exercisable beginning three years from the effective date of the grant for a
period of six months.  Options were granted at $5.89/share, the per share price
at the time of the option grant.  A total of 29,000 shares were granted to key
employees, and as of October 14, 1996, 24,500 option shares were outstanding.
Ms. DeYoung was granted an option to purchase 2,500 shares.  No options were
granted to Mr. Barnes or Mr. Phillips.     
    
    In November 1995, the Board ratified a ten-year option plan pursuant to
which qualified options to purchase up to an aggregate of 100,000 shares of
LexaLite's Common Stock may be granted to certain key employees, effective
January 1995.  Options are exercisable beginning three years from the effective
date of the grant for a period of six months.  Options were granted effective at
$7.85/share, the per share price at the time of the option grant.  A total of
6,050 shares were granted to 15 employees, and as of October 14, 1996, 6,050
option shares were outstanding.  Mr. Barnes was granted an option to purchase
1,000 shares at $8.64/share, a price which was 110% of  the per share price at
time of grant due to his percentage ownership LexaLite.  No options were granted
to Mr. Phillips or Ms. DeYoung.     
    
    In May 1996, the Board approved a second grant under the qualified stock
option plan for key employees effective January 1996.  Options were granted at
$8.48/share, the per share price at the time of the option grant.  A total of
20,000 shares were granted to 30 employees, and as of October 14, 1996, 20,000
option shares were outstanding.  Mr. Barnes was granted an option to purchase
2,500 shares at $9.33/share, a price which was 110% of current per share price
at time of option grant due to his percentage ownership LexaLite.  No options
were granted to Mr. Phillips or Ms. DeYoung.     
 
    For a description of certain options granted in connection with termination
of LexaLite's Stock Award Bonus Plan, effective July 1, 1996, in anticipation of
the Merger, see "Stock Award Bonus Plan."

Certain Transactions
- --------------------

    Josh T. Barnes, LexaLite's Chief Executive Officer, owns and operates
Business Activities Corporation (B.A.C.), a Michigan corporation.  LexaLite pays
commissions to B.A.C. for sales of "800 Series" proprietary product, pursuant to
a Design and Consulting Agreement effective January 1, 1993.  LexaLite paid
B.A.C. commissions of $85,000, $107,000, and $131,000 for the fiscal years 1994,
1995 and 1996, respectively.  In the opinion of the management of LexaLite, the
commissions paid to B.A.C. are comparable to those that could be arranged with
an unrelated party.

    Mr. Barnes currently has a Non-Compete Agreement with LexaLite to become
effective in the event of termination of employment and/or the Consulting
Agreement between LexaLite and B.A.C.  This Agreement provides for payments
equal to the higher of (1) the amount then currently being paid by LexaLite for
similar covenants; (2) the amount last paid for such covenants if none now exist
or; (3) $3,500 per month, payable the first day of each month.  The Agreement
expires ten (10) years following the date of the first such payment.  For a
description of modifications to the Non-Compete Agreement that will become
effective upon consummation of the Merger, see "Description of the Merger -
Interests of Certain Persons in the Merger."

    Arthur R. Marshall, a Director and Chairman of the LexaLite Board of
Directors, currently is paid $30,000 annually, in monthly payments, pursuant to
a Non-Compete Agreement originally effective in 1989 and renewed annually
thereafter.  Mr. Marshall's Non-Compete Agreement will terminate upon
consummation of the Merger.

    Wilfred G. Cryderman, a Director, is currently paid $30,000 annually, in
monthly payments, pursuant to a Non-Compete Agreement originally effective in
1989 and renewed annually thereafter.  Mr. Cryderman's Non-Compete Agreement
will terminate upon consummation of the Merger.

    Deakin Business Services (D.B.S.) provides cleaning services to the LexaLite
office facilities located in Charlevoix, Michigan.  As outside contractors, the
D.B.S. contracts are competitively bid annually and subject to only reasonable
notice for termination.  Thomas M. Phillips, President of LexaLite, has a
relationship by marriage to the ownership of D.B.S. (parent of spouse).

    Patricia A. DeYoung, Chief Administrative Officer of LexaLite, owns
Austrasia Export Corporation, originally started in 1980 by Josh T. Barnes
(C.E.O.) and ultimately sold to Ms. DeYoung.  Austrasia has a Sales
Representation Agreement with LexaLite for certain non-O.E.M. sales not
otherwise serviced by LexaLite, paying list price to LexaLite for products sold
to these selected customers.  Sales for fiscal years 1995 and 1996 were $32,843
and $11,674, respectively.

Employee Stock Ownership Plan
- -----------------------------

    LexaLite has an Employee Stock Ownership Plan, the primary purpose being to
provide retirement benefits to substantially all of its employees.  Benefits are
payable in the form of LexaLite's Common Stock, which under specific conditions
LexaLite is obligated to repurchase.  LexaLite provides a discretionary
contribution to the ESOP as determined by the Board of Directors which is then
allocated to the participants' accounts annually based on hours of service,
compensation and vesting parameters.  An employee typically becomes 100% vested
following five years of service.  In fiscal year 1995, the total company
contribution to the Plan was $278,000.  In fiscal year 1996, the total company
contribution to the Plan was $143,000, with 191 active participants.

    The LexaLite ESOP is administered by an Administrator, currently Josh T.
Barnes, the Chief Executive Officer and a director of LexaLite.  NBD Bank, N.A.,
serves as the trustee of the ESOP Trust, which holds shares of LexaLite Common
Stock for the ESOP.  The trustee has voting and limited investment power over
shares held by the ESOP Trust that have not been allocated to individual
accounts.  The Administrator has the power to direct the trustee as to the
voting of shares held by the ESOP Trust that have not been allocated to
individual accounts.  The Administrator has the power to direct the trustee as
to the voting of shares held by the ESOP Trust that have not been allocated to
individual accounts.  In addition, the Administrator has the power to direct the
trustee as to the voting of shares held by the ESOP Trust that have been
allocated to individual accounts unless the ESOP Trust receives a loan or other
extension of credit to purchase LexaLite Common Stock or more than 10% of the
ESOP's assets are invested in LexaLite Common Stock, in which event participants
have the right to vote the shares allocated to their accounts on any corporate
matter involving the merger, consolidation, recapitalization, reclassification,
liquidation or dissolution of LexaLite or the sale of substantially all of
LexaLite's assets or any similar transaction.  The trustee and the Administrator
disclaim beneficial ownership of shares held by the ESOP Trust (except shares

                                       58
<PAGE>
 
allocated to the person's individual account under the ESOP), and the ESOP
shares are not reported as beneficially owned by the trustee or the
Administrator as individuals unless the shares have been allocated to the
person's individual account under the ESOP.

    The LexaLite ESOP currently provides that the right of participants to
receive cash (determined in accordance with a specified formula) in lieu of
shares of LexaLite's Common Stock will terminate if the shares owned by the ESOP
trust were publicly traded, a circumstance that would result upon issuance of
registered shares of Summa's Common Stock in exchange therefor as a consequence
of the Merger.  However, the Reorganization Agreement specifies that the
LexaLite ESOP will be modified following the Merger to provide current
participants who receive distributions of shares of stock pursuant to the
provisions of the ESOP during the three full years following the Merger with the
option to cause the ESOP to purchase the shares of Summa's Common Stock issued
for their respective accounts as a consequence of the Merger at a price
determined in accordance with the existing formula, rather than receive a
distribution of the shares which must then be sold in the public marketplace.
In addition, the Reorganization Agreement provides that the shareholders of
Summa will be asked to approve the adoption by Summa of the LexaLite ESOP,
modified as described above and as may further be required, in order to permit
the employees of Summa and its other operating subsidiaries to participate
therein in accordance with such provisions for contribution as may be adopted by
the respective boards of directors of Summa and its other operating
subsidiaries, to provide that future contributions thereto may be made either in
cash or in shares of Summa's Common Stock, and to authorize the ESOP to borrow
money for the purchase of Common Stock either in the public market or directly
from ESOP participants.  Accordingly, by approving the Merger the shareholders
of Summa will also approve the adoption by Summa of the LexaLite ESOP as a Summa
ESOP, modified as summarized above.

401(k) Plan
- -----------
    
    LexaLite has adopted a Section 401(k) Plan benefitting substantially all
employees in compliance with relevant ERISA regulations.  The Plan allows
employees to defer specified percentages of their compensation, as defined, in a
tax-exempt trust.  LexaLite is required to make matching contributions, as
defined, to the Plan and may make additional profit-sharing contributions at the
discretion of the Board of Directors.  The total LexaLite contribution to all
employees' 401(k) accounts in fiscal 1996 was $289,500.     

Limitation of Directors' and Officers' Liability and Indemnification
- --------------------------------------------------------------------

    As permitted by Delaware law, LexaLite's Certificate of Incorporation
eliminates, with certain exceptions, the personal liability of a director to the
corporation or its stockholders for monetary damages for breach of the
director's fiduciary duty as a director.  A director's monetary liability is not
limited, however, with respect to (a) breaches of the director's duty of loyalty
to the corporation or its stockholders; (b) acts or omissions not in good faith
or involving intentional misconduct or a knowing violation of law; (c) unlawful
dividends, stock repurchases or redemptions; or (d) transactions from which the
director received an improper personal benefit.  A LexaLite director's monetary
liability also is not limited with respect to violations of federal or state
securities laws.  The limitations on director liability included in LexaLite's
Certificate of Incorporation do not affect the availability of non-monetary
remedies such as injunctive relief or rescission.

    LexaLite's Bylaws provide that LexaLite must indemnify its directors,
officers, employees and agents to the fullest extent permitted by Delaware law.
Delaware generally permits indemnification of expenses incurred in the defense
or settlement of a derivative or third-party action, provided there is a
determination by a majority vote of disinterested directors (even though less
than a quorum) or, if there are no such directors, or if such directors so
direct, by independent legal counsel in a written opinion, or by the
stockholders, that the person seeking indemnification acted in good faith and in
a manner he reasonably believed to be in or not opposed to the best interests of
the corporation and, with respect to a criminal proceedings, which he had no
reasonable cause to believe his conduct was unlawful.  Without court approval,
however, no indemnification may be made in respect of any derivative action in
which the person is adjudged liable to the corporation.  Delaware law requires
indemnification of expenses when the individual being indemnified has
successfully defended the action on the merits or otherwise.  LexaLite's Bylaws
provide that its indemnification requirements are not exclusive of any other
rights to which an indemnified person may be entitled under any Bylaw,
agreement, vote of stockholders or disinterested directors or otherwise, both as
to action in the indemnified person's official capacity and as to action in
another capacity while a director, officer, employee or agent of LexaLite.
LexaLite's Bylaws further provide that its indemnification requirements continue
with respect to a person who has ceased to be a director, officer, employee or
agent of LexaLite and will inure to the benefit of the heirs, executors and
administrators of that person.

                                       59
<PAGE>
 
                          ELECTION OF SUMMA DIRECTORS

    In the event that the shareholders of Summa approve the Merger, Summa's
current Board of Directors will nominate three (3) individuals, Michael L.
Horst, James R. Swartwout, and Josh T. Barnes, for election as directors of
Summa at the Summa Annual Meeting, each to serve as such for a three-year term
and until their respective successors are elected and qualified.  Messrs. Horst
and Swartwout are both members of Summa's Board of Directors whose current terms
are expiring as of the Summa Annual Meeting.  Mr. Barnes is the Chief Executive
Officer and a director of LexaLite.  In addition, three additional incumbents,
Coalson C. Morris, Karl V. Palmaer and Byron C. Roth, will be nominated for re-
election by Summa's current Board of Directors of Summa at the Summa Annual
Meeting, each to serve as such for a two-year term and until their respective
successors are elected and qualified.

    Should the shareholders of Summa fail to approve the Merger, only the four
incumbent directors whose terms are expiring as of the Summa Annual Meeting,
Messrs. Morris, Horst, Swartwout, and Palmaer will be nominated by Summa's
current Board of Directors for re-election at the Summa Annual Meeting, each to
serve a new two-year term and until their respective successors are elected and
qualified.

    In accordance with Summa's Articles of Incorporation, there will be no
cumulative voting for the election of directors.  Accordingly, the six nominees
(if the Merger is approved) or four nominees (if the Merger is not approved), as
the case may be, receiving the highest number of votes at the Summa Annual
Meeting, will be elected.  In the event that the Merger is not consummated for
any reason, despite the approval thereof by the shareholders of Summa, the
amendment of Summa's Articles of Incorporation to establish a 9-member
classified board of directors will not be implemented and only the four
incumbent directors whose terms are expiring will deemed to have been elected to
the Summa Board of Directors, each to serve a new 2-year term.

    For additional information regarding the incumbent directors of Summa who
will be nominated for re-election as directors at the Summa Annual Meeting, see
"Information Concerning Summa - Management of Summa."  For additional
information regarding Mr. Barnes, see "Information Concerning LexaLite -
Management of LexaLite.  Although it is not presently contemplated that any
nominee will decline or be unable to serve as a Director, in either such event,
the proxies will be voted by the proxy holders for such other persons as may be
designated by the present Board of Directors should any nominee become
unavailable to serve.

    Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), requires the executive officers and directors of Summa, and
persons who own more than ten percent of a registered class of Summa's equity
securities, to file reports of ownership and changes in ownership (Forms 3, 4
and 5) with the Securities and Exchange Commission.  Executive officers,
directors and greater-than-ten-percent shareholders are required to furnish
Summa with copies of all such forms which they file.  To Summa's knowledge,
based solely on Summa's review of such reports or written representations from
certain reporting persons that no Forms 5 were required to be filed by those
persons, Summa believes that during the year ended December 31, 1995, all filing
requirements applicable to its executive officers, directors, and other persons
subject to Section 16 of the Exchange Act were complied with.


                                 OTHER MATTERS

    Neither the Board of Directors of Summa nor the Board of Directors of
LexaLite is aware of any other business to be presented for consideration at the
Summa Annual Meeting or the LexaLite Special Meeting, respectively.  If any
other business should properly come before either meeting, the proxies will be
voted in accordance with the best judgment of the proxy holders.

                                 LEGAL MATTERS

    Phillips & Haddan, Newport Beach, California, counsel to Summa, has rendered
an opinion to Summa (which has been filed as an exhibit to the Registration
Statement of which this Joint Proxy Statement/Prospectus is a part), to the
effect that Summa's Common Stock to be issued as a consequence of the Merger
will, when issued the shares as described herein, be validly issued and fully
paid and nonassessable.  Pointner, Joseph & Corcoran, P.C. will pass on certain
legal matters in connection with the Merger for the stockholders of LexaLite.

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, 1995 and 1996 and
the related consolidated settlements of income, shareholders' equity and cash
flows for each of the three years in the period ended August 31, 1996. These
financial statements are the responsibilty 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 disclosure 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, 1995 and 1996, and the results of their operations
and their cash flows for each of the three years in the period ended August 31,
1996, in conformity with generally accepted accounting principles.

As discussed in Note 7 to the consolidated financial statements, effective 
September 1, 1993, the Company changed its method of accounting for income 
taxes.


                                                             ARTHUR ANDERSEN LLP

SUMMA INDUSTRIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED AUGUST 31, 1994, 1995 AND 1996.

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 two wholly-owned subsidiaries, KVP Systems, Inc. and GST Industries,
Inc.  Summa's subsidiaries manufacture proprietary industrial components.
Products include 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 of the Company include SUMMA and its
wholly-owned subsidiaries, GST Industries, Inc., KVP Systems, Inc. and Fullerton
Holdings, Inc.  The consolidated financial statements also include Morehouse-
COWLES, Inc. (Morehouse-COWLES"), for the years ended August 31, 1994, 1995 and
for the nine month period ended May 31, 1996, when Morehouse-COWLES was
discontinued (see Note 15). All intercompany account balances and transactions
have been eliminated in consolidation.  Certain reclassifications of 1994 and
1995 amounts have been made to conform to 1996 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.

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.

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).

                                      F-6
<PAGE>
 
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 1,548,000, 1,553,000, and 1,603,000 for 1994,  1995, and 1996, respectively

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.

PENDING ACCOUNTING PRONOUNCEMENTS

In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 121 "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."  SFAS No. 121
requires that long-lived assets and certain identifiable intangibles to be held
and used to be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable based on the estimated future cash flows (undiscounted and without
interest charges).  SFAS No. 121 also requires that long-lived assets and
certain identifiable intangibles to be disposed of be reported at the lower of
carrying amount or fair value less costs to sell.  Summa plans to adopt SFAS No.
121 as of September 1, 1996 and believes the effect of adoption will not be
material to the financial statements.

In October 1995, the Financial Accounting Standards Board issued SFAS No. 123
"Accounting for Stock-Based Compensation."  Under SFAS No. 123, companies have
the option to implement a fair value-based accounting method or continue to
account for employee stock options and stock purchase plans using the intrinsic
value-based method of accounting as prescribed by Accounting Principles Board
(APB) Opinion No. 25 "Accounting for Stock Issued to Employees."  Entities
electing to remain under APB Opinion No. 25 must make pro-forma disclosures of
net income or loss and earnings per share as if the fair value-based method of
accounting defined in SFAS No. 123 had been applied.  SFAS No. 123 is effective
for financial statements for fiscal years beginning after December 15, 1995.
The Company has tentatively determined it will continue to account for stock
options under APB Opinion No. 25.

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 a
  reasonable estimate of fair value since the interest rate approximates long-
  term interest rates available on government debt securities.

  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 at August 31:

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 $916,000 at
August 31, 1996. The lease is for ten years with an option 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.

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.

Effective September 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes".  This standard
requires income taxes to be accounted for under the liability method and
calculates deferred tax balances using tax rates in effect when the taxes will
be paid.  Included in the consolidated statement of income for the year ended
August 31, 1994, is a cumulative benefit of $100,000, or $.06 per share, which
represents a cumulative adjustment to recalculate deferred tax balances.  Prior
years' financial statements have not been restated as a result of this change.

8.  NOTES PAYABLE AND LONG-TERM DEBT

The Company has a term loan from an officer of a subsidiary with an outstanding
balance in the amount of $300,000 at August 31, 1996, secured by the Company's
real estate in Fullerton, California.  Interest payments on the term loan are
due monthly at 8  1/2 percent.  The Company paid interest on the term loan of
$32,000, $32,000 and $33,000 for the years ended August 31, 1994, 1995 and 1996,
respectively.

Principal payments on the term loan are due in subsequent years as follows:

In January 1996, the Company renewed an agreement with a bank for a $2,000,000
line of credit of which none was in use at August 31, 1996.  Interest is due
monthly at the rate of Prime (8.25% at August 31, 1996) plus 1/4%.  The line of
credit is secured by all the assets of the Company and expires January 1, 1997.
The line of credit requires the maintenance of certain financial ratios and
minimum levels of working capital and net worth, as defined, as well as other
requirements.

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 has filed
counterclaims.  The case is in discovery and could go to trial during fiscal
1997.  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.  Although the
Company believes it has a reasonable expectation of prevailing, because no
accrual for the case has been established, the consequences of an adverse
determination would impact 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.

In connection with the acquisition of GST Industries, Inc. in fiscal 1992, the
Company is required to make annual payments to former shareholders of GST
related to GST's performance  through October 29, 1996.  Payments are equal to
75 percent of the amount by which annual operating profit of the subsidiary GST
Industries, Inc. exceeds a threshold of $500,000, up to an aggregate amount of
$1,500,000.  Thereafter, additional consideration for covenants not to compete
with the Company can be earned at the rates of 75% of the amount by which annual
operating profit of subsidiary GST Industries, Inc. exceeds $500,000 up to an
aggregate amount of $500,000 and thereafter, 25%, up to a cumulative aggregate
amount of an additional $1,500,000.  In the event that operating profit for any
fiscal year does not exceed the threshold for that year, the threshold for the
subsequent year will be increased by the amount of such deficit.  No additional
performance payments shall be earned either after the aggregate of $1,500,000
has been earned or after October 1996.  No additional non-compete covenant
consideration shall be earned either after the aggregate of $1,500,000 has been
earned or after October 1996.  Payments of $620,000, $178,000 and $478,000 were
earned in fiscal 1994, 1995 and 1996, respectively.  The cumulative amount
earned at August 31, 1996 was $2,026,000.  Of the amounts of performance
payments paid, only 40 1/2% is deductible for income tax purposes.  The amount
of non-compete covenant consideration paid is fully tax deductible.

The Company leases office and manufacturing facilities and certain equipment
under noncancelable operating leases which expire at various dates through April
2001.  Rental expense charged to operations was approximately $199,000, $266,000
and $308,000 for the years ended August 31, 1994, 1995 and 1996, respectively.

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

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 $49,000, $87,000 and $93,000 was related to discontinued operations
and accordingly was allocated to discontinued operations for fiscal years 1994,
1995 and 1996, respectively. As a consequence of holding Morehouse-COWLES for
sale, the assets and liabilities of discontinued operations have been classified
in the consolidated balance sheets as, "Net assets of discontinued operations."
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 $5,555,000, $8,097,000 and
$5,638,000 for the  years ended August 31, 1994, 1995 and 1996, respectively.

  The components of net assets of discontinued operations included in the
consolidated balance sheets at August 31, 1995 and 1996 are as follows:

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


To the Shareholders and Board of Directors of
LexaLite International Corporation:

We have audited the accompanying balance sheets of LEXALITE INTERNATIONAL
CORPORATION (a Delaware corporation) as of June 30, 1996 and 1995, and the
related statements of income, shareholders' equity and cash flows for the three
years in the period ended June 30, 1996, as restated, see Note 9.  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 LexaLite International
Corporation as of June 30, 1996 and 1995, and the results of its operations and
its cash flows for the three years in the period ended June 30, 1996, in
conformity with generally accepted accounting principles.

As explained in Note 9 to the financial statements, the Company has given
retroactive effect to the change from the last-in, first-out to the first-in,
first-out method of determining the cost of its inventories.

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES

        Description of Business
        -----------------------

          LexaLite International Corporation (the "Company") is engaged in the
            manufacture and sale of plastic molded injection parts and providing
            design and development services. The majority of the Company's net
            sales and accounts receivable are with customers in the lighting
            industry.

        Cash and Cash Equivalents
        -------------------------

          The Company considers all highly liquid instruments purchased with an
            original maturity of three months or less to be cash equivalents.
            Cash equivalents are recorded at cost, which approximates current
            market value.

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

          Property, plant and equipment are stated at cost.  Depreciation is
            computed over the estimated useful lives of the assets using the
            straight-line method for financial reporting purposes and primarily
            accelerated methods for income tax purposes.

          Estimated lives used to depreciate fixed assets for book purposes are
            as follows:

                  Office furniture and fixtures       5-10
                  </TABLE>

          During fiscal year 1995, the Company constructed a 27,500 square foot
            industrial facility ("the Facility") to be used for the research,
            development and manufacture of plastic injection molded products.

        Bond Proceeds Held in Trust
        ---------------------------

          Unexpended bond proceeds are restricted for use to finance the
            construction of the Facility and related equipment.  The unexpended
            proceeds are invested in short-term marketable securities, and are
            stated at cost which approximates market, together with accrued
            interest.  Investments must be rated at least A-1 by Standard and
            Poor's or an equivalent rating by a similarly recognized rating
            service.

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES, continued

        Long-Term Assets
        ----------------

          In March 1995, the Financial Accounting Standards Board issued
            Statement No. 121, "Accounting for the Impairment of Long-Lived
            Assets and for Long-Lived Assets to be Disposed of" (SFAS 121). The
            Company is required to adopt the provisions of SFAS 121 beginning in
            fiscal 1997. Based on the information currently available, the
            Company does not expect the adoption to have a material effect on
            its financial condition or results of operations.

        Research and Development
        ------------------------

          Research and development costs related to the planning and development
            of new and existing products are charged to operations as incurred.

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

          The earnings per share are computed based on the weighted average
            number of common shares outstanding and, to the extent dilutive,
            common share equivalents. The weighted average number of shares
            outstanding were approximately 1,477,000, 1,427,000, and 1,385,000
            in 1996, 1995, and 1994, respectively.

        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 disclosures 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.

(2)  INVENTORIES

        Inventories are stated at the lower of cost or market and include
            materials, labor and manufacturing overhead. Cost is determined
            using the first, first-out (FIFO) method. Inventories consisted of
            the following as of June 30,:

(3)  LONG-TERM DEBT AND FINANCING ARRANGEMENTS

       During fiscal 1995, the Company issued $5,000,000 of Michigan Strategic
         Fund Limited Obligation Revenue Bonds Series 1994 to finance the
         construction of the Facility and certain related equipment. The bonds
         mature at various dates from November 1997 through November 2001 at an
         average effective interest rate of 6.09% and are secured by
         substantially all assets of the Company and an irrevocable letter of
         credit.

       The Company has available a secured line of credit with a bank which
         provides for $3,000,000 in maximum borrowings and matures on October 1,
         1996.  No borrowings were outstanding under this agreement at June 30,
         1996.  Interest is payable at the bank's prime rate (8.25% at June 30,
         1996).  The weighted average interest rate on borrowings was 6.8% and
         8.4% in 1996 and 1995, respectively.

       The Company also has a credit agreement with a bank to borrow up to
         $1,250,000 for the purchase of equipment. The agreement expires
         December 1, 1996. No borrowings have been made against this
         arrangement. Interest is payable at the bank's prime rate.

     Under the terms of certain of its loan agreements, the Company must
       maintain specified levels of net worth and certain other performance
       ratios.  The Company was in compliance with all covenants throughout the
       year.

     Cash expended for interest on debt was approximately $704,000, $719,000,
       and $496,000 in 1996, 1995, and 1994, respectively.  Capitalization of
       interest related to the project discussed in Note 1 reduced interest
       expense by approximately $185,000 in 1995.  No interest was capitalized
       in 1996 or 1994.

(6)  INCOME TAXES

      The Company applies the "liability" method of accounting for income taxes.
        Under this method, deferred tax assets and liabilities are determined
        based on the difference between the financial statement and tax bases of
        assets and liabilities using enacted tax rates in effect for the year in
        which differences are expected to be reversed.

(9)  CHANGES IN PRIOR PERIOD FINANCIAL STATEMENTS

        During 1996, the Company changed its method of accounting for inventory
          from the last-in, first-out (LIFO) method to the FIFO method. Under
          the current economic environment, the Company believes that the FIFO
          method will result in a better measurement of operating results.
          During 1996, the Company also corrected the amount charged to
          operations for the stock bonus in 1995 as well as the accounting for
          deferred taxes in 1994. As a result, the Company has retroactively
          restated the accompanying financial statements.

        The following effects of the change in accounting principle and the
          corrections discussed above have been reflected in the accompanying
          financial statements as follows:

(10)   RELATED PARTY TRANSACTIONS
 
        The Company pays commissions on certain proprietary products to a
          company owned by an officer of the Company. The commissions are based
          upon a design and consulting agreement which became effective in
          January, 1993. Commissions paid were approximately $131,000, $107,000
          and $85,000 in 1996, 1995 and 1994, respectively. In management's
          opinion, the fees paid are comparable to those that could be arranged
          with an unrelated party.

(11) SUBSEQUENT EVENT

                                  ARTICLE III

                       TREATMENT OF SHARES OF EACH OF THE
                            CONSTITUENT CORPORATIONS

     3.1  On the Effective Date:

          (a)  Subject in all events to the provisions of Section 3.1(c) below,
each share of LexaLite's Common Stock outstanding immediately prior to the
Merger shall, by virtue of the Merger and without any action on the part of the
holder thereof, be converted into and become the right to receive one and one-
half (1.5) shares of the Common Stock of Summa;

          (b)  Subject in all events to the provisions of Section 3.1(c) below,
all options, warrants and other rights to purchase shares of LexaLite's Common
Stock outstanding immediately prior to the Merger shall have been canceled as of
the Effective Time by agreements with the holders thereof to accept, in the
place thereof, options to purchase shares of Summa Common Stock, all as provided
in Section 10.7 of the Reorganization Agreement.

          (c)  In the event that the average closing price of Summa Common Stock
on The Nasdaq National Market during the 5 consecutive trading days ending on
and including the third trading day prior to the date on which the meeting of
LexaLite's Stockholders has been called for the purpose of voting on the Merger
is less than $6.66 per share, LexaLite may notify Summa of Lexalite's intention
to terminate this Agreement and the transactions contemplated hereby unless the
number of shares of Summa Common Stock issuable to the stockholders of LexaLite
as a consequence of the Merger is increased as provided below. Upon receipt of
such notification, Summa may elect to (i) terminate this Agreement and the
transactions contemplated hereby, or (ii) to increase the number of shares of
Summa Common Stock issuable to the stockholders as a group to that number of
shares of Summa Common Stock which would have an aggregate value (based upon the
average closing price calculated as provided above) equal to $15,000,000.

          (d)  Each share of Subsidiary's Common Stock outstanding immediately
prior to the Merger shall, by virtue of the Merger and without any action on the
part of the holder thereof,

                                      I-3
<PAGE>
 
be converted into and become one fully paid and nonassessable share of Common
Stock, $1.00 par value, of the Surviving Corporation.

                                      I-4
<PAGE>
 
          (e)  Shares of Summa Common Stock shall not be issued as a consequence
of the Merger in respect of shares of LexaLite Common Stock owned by LexaLite
immediately prior to the Effective Time, if any, and as of the Effective Time
any and all such shares of LexaLite Common Stock owned by LexaLite shall be
canceled and retired, and all rights in respect thereof shall cease to exist.
 
     3.2  After the Effective Date, each holder of an outstanding certificate or
certificates theretofore representing shares of LexaLite Common Stock shall
surrender such certificate or certificates to the Exchange Agent (as defined in
Section 1.18 of the Reorganization Agreement) and shall receive in exchange
therefor certificates representing the number of whole shares of Summa Common
Stock into which the shares of LexaLite Common Stock theretofore represented by
the certificate or certificates so surrendered (together with cash in lieu of a
fractional share, if any, as provided in Section 3.3 below).  After the
Effective Time, certificates formerly representing shares of LexaLite Common
Stock shall be deemed for all purposes, other than the payment of dividends or
other distributions, if any, payable to holders of record of shares of Summa
Common Stock as of any date subsequent to the Effective Date, to evidence the
number of shares of Summa Common Stock into which such shares of LexaLite Common
Stock have been converted under Section 3.1(a) hereof; provided, however, that
                                                       -----------------      
upon surrender and exchange of such outstanding certificates theretofore
representing shares of LexaLite Common Stock there shall be paid by the Exchange
Agent to the record holders of the certificates issued in exchange therefor, the
amount, without interest thereon, of dividends and other distributions, if any,
which theretofore have become payable with respect to the number of whole shares
of Summa Common Stock represented thereby.

     3.3  No fractional shares of Summa Common Stock and no scrip certificates
therefor shall be issued to represent any fractional share interests in shares
of Summa Common Stock, and such fractional share interest shall not entitle the
owners thereof to vote, to receive dividends, or to exercise any other right of
shareholders of Summa.  In lieu of a fractional share or scrip certificate, each
holder of a share of LexaLite Common Stock otherwise entitled to a fractional
interest in a share of Summa Common Stock shall be entitled to receive a cash
payment (without interest) in an amount equal to the fraction of such share of
Summa Common Stock to which such holder otherwise would be entitled multiplied
by the average closing price of a share of Summa Common Stock determined as
provided in Section 3.1.2(c) hereof.

     3.4  Each stockholder of LexaLite, if any, and each shareholder of Summa,
if any, who becomes entitled, pursuant to the provisions of the Delaware General
Corporation Law or the California Corporations Code, respectively, to the
payment of the "fair value" of his shares of LexaLite Common Stock or Summa
Common Stock, as the case may be ("Perfected Dissenting Shares"), shall receive
payment therefor from LexaLite or Summa, as the case may be, but only if the
Merger is consummated and becomes effective and only after the value thereof
shall have been agreed upon or finally determined pursuant to such provisions.
Perfected Dissenting Shares, if any, shall be canceled.

     4.3  This Agreement may be terminated as provided in the Reorganization
Agreement at any time before or after adoption and approval hereof by the
stockholders of LexaLite or the shareholders of Subsidiary, or both, but not

shall become wholly void and of no effect, and there shall be no liability on
the part of Summa, Subsidiary or LexaLite, or the Board of Directors or
shareholders, or stockholders, as the case may be, except as provided in Section
4.4 hereof.

     4.4  If the Merger becomes effective, the Surviving Corporation shall
assume and pay all expenses in connection therewith not theretofore paid by the
respective parties.  If for any reason the Merger shall not become effective,
each of Summa and Subsidiary, on the one hand, and LexaLite, on the other hand,
shall pay all of their or its respective expenses incurred in connection with
all the proceedings taken in respect of this Agreement or relating thereto as
provided in the Reorganization Agreement.

     4.5  The parties hereto, by mutual consent of their respective Boards of
Directors, may amend, modify or supplement this Agreement in such matter as may
be agreed upon by them in writing at any time before or after adoption and
approval of this Agreement by the stockholders of LexaLite or the shareholders
of Summa, or both, but not later than the Effective Date; provided, however,
                                                          ----------------- 
that no such amendment, modification or supplement not adopted and approved by
the stockholders of LexaLite and/or shareholders of Summa shall affect the
rights of such stockholders and/or shareholders or change any of the principal
terms of this Agreement.

of each of the Constituent Corporations, and all property, real, personal and

effectually the property of the Surviving Corporation as they were of the
Constituent Corporations, and the title to any real estate vested by deed or
otherwise in either of the Constituent Corporations shall not revert or be in
any way impaired by reason of the Merger; provided, however, that the

liabilities of the Constituent Corporations and of their shareholders,
directors, and officers shall not be affected and all rights of creditors and
all liens upon any property of either of the Constituent Corporations shall be
preserved unimpaired, and any claim existing or action or proceeding pending by
or against either of the Constituent Corporations may be prosecuted to judgment
as if the Merger had not taken place except as they may be modified with the
consent of such creditors, and all debts, liabilities and duties of each of the
Constituent Corporations shall attach to the Surviving Corporation, and may be
enforced against it to the same extent as if such debts, liabilities and duties
had been incurred or contracted by it.

     5.2  The parties hereto agree that, from time to time and as when requested

Gentleman:

You have requested our opinion as to the fairness, from a financial point of
view, to the Stockholders of LexaLite International Corporation ("LexaLite")
and the shareholders of Summa Industries ("Summa") (together the "Companies")
of the proposed merger (the "Merger") contemplated by the Agreement and Plan of
Reorganization dated as of July 18, 1996 by and between LexaLite and Summa (the
"Merger Agreement").

The Merger Agreement proposes that Charlevoix The Beautiful, Inc., a 
newly-to-be-formed California corporation which will be a wholly-owned 
subsidiary of Summa will be merged with and into LexaLite, with LexaLite being 
the surviving corporation. In addition, each outstanding share of LexaLite 
Common Stock, as a consequence of Merger, shall be converted into one and 
one-half (1.5) shares of Summa Common Stock. If the average daily closing price 
per share of Summa Common Stock as reported on the Nasdaq National Market for 
the five consecutive trading days ending on the close of trading on the third 
trading day preceding the date on which the LexaLite Stockholders shall meet to 
vote on the Merger (the "Base Period Trading Price") is less than $6.66, 
LexaLite may notify Summa of LexaLite's intention to terminate the Merger unless
the number of shares issued to the LexaLite Stockholders is increased as
provided below. Upon receipt of such notice, Summa may elect to (i) terminate
the Merger, or (ii) to increase the number of shares of Summa Common Stock
issuable to the LexaLite Stockholders to that number of shares of Summa Common
Stock which would have an aggregate value (based on the average closing price as
provided above) equal to $15 million. Summa has advised LexaLite that in all
likelihood Summa would not elect to increase the number of shares of Summa
Common Stock issuable to the LexaLite Stockholders as provided above if the
increased number of shares would exceed three million.

Wedbush Morgan Securities is an investment banking firm and a member of the 
New York Stock Exchange and other principal stock exchanges in the United 
States, and is regularly engaged as part of its business in the valuation of 
businesses and their securities in connection with mergers and acquisitions,

In arriving at our opinion set forth below, we have reviewed, among other
things, draft versions of the Agreement and Plan of Reorganization by and
between LexaLite and Summa; audited financial settlements of LexaLite for the
fiscal years ended June 30, 1992 through June 30, 1996; LexaLite's State of the
Corporation report for the third quarter ended March 30, 1996; projections
prepared by LexaLite with respect to LexaLite for the fiscal year ending June
30, 1997 through June 30, 2001; Valuation Report of LexaLite as of December 31,
1995 prepared by BDO Seidman, LLP; Annual Report to Shareholders of Summa for
the fiscal years ended August 31, 1991 through August 31, 1995; Annual Report on
Form 10-K of Summa for the fiscal years ended August 31, 1991 through August 31,
1995; Quarterly Report on Form 10-Q of Summa for the quarter ended May 31, 1996;
draft audited financial statements of Summa for the fiscal year ended August 31,
1996; Proxy Statement for Annual Meeting of Stockholders of Summa dated December
14, 1995; Form 8-K reporting the sale of Morehouse-COWLES, Inc. to J.B. Jennings
and Bret Lewis; projections of the consolidated operations of Summa for the
fiscal year ending August 31, 1997; the KVP Systems, Inc. subsidiary for the
three fiscal years ending August 31, 1999; and the GST Industries, Inc. and
Stang subsidiaries for the five fiscal years ending August 3, 2001.

We have held discussion with certain members of the senior management of both
LexaLite and Summa regarding the past and current business operations, financial
condition, future prospects and projected operations and performance of the
Companies. We have toured the headquarters of Summa in Torrance, California and
the operating plants of Summa in Santa Ana and Rancho Cordova, California. In
addition, we have reviewed the reported price and trading activity of Summa's
Common Stock, compared certain statistical and financial information for
LexalIte and Summa, respectively, with similar information for certain publicly
traded companies in the same industries as LexaLite and Summa, respectively;
reviewed and compared statistical and financial data for recent acquisitions in
the same industries and LexaLite and Summa and conducted such other financial
studies, analyses and inquiries and considered such other matters as Wedbush
Morgan Securities deemed necessary and appropriate for this opinion.

 We have not undertaken any obligation to independently verify the accuracy or 
completeness of financial information or other information furnished to us by 
LexaLite or Summa orally or in writing, or other information obtained from 
publicly available sources and reviewed by us for purposes of this opinion. We 
were provided with information represented to us as the best currently available
estimates and judgements of the management of LexaLite and Summa, as to the 
expected future financial and operating performance of LexaLite and Summa, and 
we have assumed that they have been reasonably prepared and have not undertaken 
any responsibility for the accuracy of such forecasts, estimates or judgements 
nor have we undertaken any obligation independently to verify the underlying 
assumptions made in connection with such forecasts, estimates or judgements. In 
addition, we have not made an independent evaluation or appraisal of any 
particular assets or liabilities of LexaLite or Summa, and we have not been 
furnished with any such evaluation or appraisal.

We note that KVP Systems, Inc., a subsidiary of Summa, is a party to certain 
legal proceedings, Laitram, et al v. KVP Systems, Inc., pending before the 
Federal District Court in Sacramento, California, regarding the validity of two 
patents which the plaintiffs claim KVP Systems, Inc. has infringed. KVP Systems,
Inc. contends the claims are invalid, and has filed counterclaims that the
plaintiffs have sued in bad faith and acted in restraint of free trade. The case
is in an advanced stage discovery and is expected to be heard in court during
Summa's fiscal 1997. This opinion is based on the assumption that the outcome of
such legal proceedings will not have a material adverse effect on the financial
position of Summa. We have relied, with your consent, exclusively on the
judgement of the management of LexaLite and Summa that such assumption can be
made. We do not take any responsibility for the accuracy of such assumption nor
do we undertake any obligation to verify independently such assumption.

We have not negotiated, or participated in any way in the negotiation of, the
terms of the Merger or advised you regarding strategic alternatives. We have not
been asked to consider, and this opinion does not address, the relative merits
of the Merger as compared to any alternative business strategies that might
exist for the Company or the effect of any other transaction in which the
Company might engage.

We do not express any opinion as to the market value of Summa Common Stock to be
received by LexaLite stockholders, or the price or trading range at which shares
of Summa Common Stock will trade following consummation of the Merger. Our
opinion necessarily is based on economic, monetary and market conditions
prevailing, and other circumstances and considerations existing on the date of
this opinion. Nothing contained in this opinion shall be construed as creating
or imposing upon us any undertaking or obligation to advise any person of any
change in any fact or matter affecting our opinion of which we become aware
after the date hereof.

In the normal course of our business, we may, from time and time, actively trade
securities of Summa for our own account or the account of our customers and,
accordingly, may at any time have a long or short position in such securities. 
Additionally, we or our affiliates may, from time to time, produce research 
materials regarding Summa. Since the date of our engagement with respect to the 
Merger, we have not held a long or short position for our own account in Summa 
Common Stock. Prior to this transaction, we had not even engaged to provide
investment banking services to LexaLite or Summa.
 
Based upon and subject to the foregoing and based upon such other matters as we 
consider relevant, it is our opinion that, as of the date hereof, the Merger is 
fair, from a financial point of view, to the Stockholders of LexaLite and the 
shareholders of Summa.

This opinion is intended for the use of the Board of Directors of the Companies
in connection with their consideration of the Merger. We recognize that the 
Companies may be required to disclose this opinion in any proxy statement 
related to the Merger, and agree that the Companies may do so, provided that 
the full text of the opinion is attached to such proxy statement and that the 
descriptions of Wedbush Morgan Securities and the opinion is such proxy 
statement are

approved by us in advance. We note, however, that the opinion is intended to be 
for the benefit of the Boards of Directors of the Companies, and not for the
benefit of stockholders or any other third parties. Our agreement to allow
disclosure of the opinion in the Companies' proxy statement is intended solely
to facilitate compliance by the Companies with their legal obligations, and
should not be construed as (1) authorizing reliance on such opinion by any
shareholder of the Companies or any other person, (2) recommending to any
shareholder how to vote regarding the Merger, or (3) implying that Wedbush
Morgan Securities is, within the meaning of Section 7 or Section 11 of the
Securities Act of 1933, an "accountant, engineer, or appraiser, or any person
whose profession gives authority to a statement made by him, who has with his
consent been named as having prepaid or certified" any part of any proxy

referred to for any purpose, except in accordance with our prior written
consent.

                            GENERAL CORPORATION LAW
                        RELATING TO DISSENTERS' RIGHTS

     262 APPRAISAL RIGHTS--(a) Any stockholder of a corporation of this State 
who holds shares of stock on the date of the  making of a demand pursuant to 
subsection (d) of this section with respect to such shares, who continuously 
holds such shares through the effective date of the merger or consolidation, 
who has otherwise complied with subsection (d) of this section and who has
neither voted in favor of the merger or consolidation nor consented thereto in
writing pursuant to (S)228 of this title shall be entitled to an appraisal by
the Court of Chancery of the fair value of his shares of stock under the
circumstances described in subsections (b) and (c) of this section. As used in
this section, the word "stockholder" means a holder of record of stock in a
stock corporation and also a member of record of a nonstock corporation; the
words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a nonstock
corporation; and the words "depository receipt" mean a receipt, or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or 
series of stock of a constituent corporation in a merger or consolidation to be 
effected pursuant to (S)(S) 251 (other than a merger effected pursuant to 
subsection (g) of 251), 252, 254, 257, 258, 263 or 264 of this title:

     (1) Provided, however, that no appraisal rights under this section shall be
available for the shares of any class or series of stock, which stock, or 
depository receipts in respect thereof, at the record date fixed to determine
the stockholders entitled to receive notice of and to vote at the meeting of
stockholders to act upon the agreement of merger or consolidation, were either
(i) listed on a national securities exchange or designated as a national market
system security on an interdealer quotation system by the National Association
of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders;
and further provided that no appraisal rights shall be available for any shares
of stock of the constituent corporation surviving a merger if the merger did not
require for its approval the vote of the holders of the surviving corporation as
provided in subsection (f) of (S) 251 of this title.

     (2) Notwithstanding paragraph (1) of this subsection, appraisal rights 
under this section shall be available for the shares of any class or series of
stock of a constituent corporation if the holders thereof are required by the
terms of an agreement of merger or consolidation pursuant to (S)(S) 251, 252,
254, 257, 258, 263 and 264 of this title to accept for such stock anything
except:

     a. Shares of stock of the corporation surviving or resulting from such 
merger or consolidation or depository receipts in respect thereof;

     b. Shares of stock of any other corporation, or depository receipts in 
respect thereof, which shares of stock or depository receipts at the effective 
date of the merger or consolidation will be either listed on a national 
securities exchange or designated as a national market system security on an 
interdealer quotation system by the National Association of Securities Dealers 
Inc. or held of record by more than 2,000 holders;

     c. Cash in lieu of fractional shares or fractional depositary receipts 
described in the foregoing subparagraphs a. and b. of this paragraph; or

     d. Any combination of the shares of stock, depository receipts and cash in 
lieu of fractional shares or fractional depository receipts described in the 
foregoing subparagraphs a., b. and c. of this paragraph.

     (3) In the event all of the stock of a subsidiary Delaware corporation 
party to a merger effected under (S) 253 of this title is not owned by the 
parent corporation immediately prior to the merger, appraisal rights shall be 
available for the shares of the subsidiary Delaware corporation.

                                     III-1

entitled to appraisal rights, may file a petition in the Court of Chancery 
demanding a determination of the value of the stock of all such stockholders. 
Notwithstanding the foregoing, at any time within 60 days after the effective 
date of the merger or consolidation, any stockholder shall have the right to 
withdraw his demand for appraisal and to accept the terms offered upon the 
merger or consolidation. Within 120 days after the effective date of the merger 
or consolidation, any stockholder who has complied with the requirements of 
subsections (a) and (d) hereof, upon written request, shall be entitled to 
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.

     (f) Upon the filing of any such petition by a stockholder, service of a 
copy thereof shall be made upon the surviving or resulting corporation, which 
shall within 20 days after such service file in the office of the Register in 
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the 
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an 
appraisal for their shares and who hold stock represented by certificates to 
submit their certificates of stock to the Register in Chancery for notation 
thereon of the pendency of the appraisal proceedings; and if any stockholder 
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court 
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or 
consolidation, together with a fair rate of interest, if any, to be paid upon 
the amount determined to be the fair value. In determining such fair value, the 
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of 
interest which the surviving or resulting corporation would have had to pay to 
borrow money during the pendency of the proceeding. Upon application by the 
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery 
or other pretrial proceedings and may proceed to trial upon the appraisal prior 
to the final determination of the stockholder entitled to an appraisal. Any 
stockholder whose name appears on the list filed by the surviving or resulting 
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may 
participate fully in all proceedings until it is finally determined that he is 
not entitled to appraisal rights under this section.

     (i) The Court shall direct the payment of the fair value of the shares, 
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

                                     III-3

     (c) Any corporation may provide in its certificate of incorporation that 
appraisal rights under this section shall be available for the shares of any 
class or series of its stock as a result of an amendment to its certificate of 
incorporation, any merger or consolidation in which the corporation is a 
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision, 
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

     (1) If a proposed merger or consolidation for which appraisal rights are 
provided under this section is to be submitted for approval at a meeting of 
stockholders, the corporation, not less than 20 days prior to the meeting, shall
notify each of its stockholders who was such on the record date for such meeting
with respect to shares for which appraisal rights are available pursuant to
subsections (b) or (c) hereof that appraisal rights are available for any or all
of the shares of the constituent corporations, and shall include in such notice
a copy of this section. Each stockholder electing to demand the appraisal of his
shares shall deliver to the corporation, before the taking of the vote on the
merger or consolidation, a written demand for appraisal of his shares. Such
demand will be sufficient if it reasonably informs the corporation of the
identity of the stockholder and that the stockholder intends thereby to demand
the appraisal of his shares. A proxy or vote against the merger or consolidation
shall not constitute such a demand. A stockholder electing to take such action
must do so by a separate written demand as herein provided. Within 10 days after
the effective date of such merger or consolidation, the surviving or resulting
corporation shall notify each stockholder of each constituent corporation who
has complied with this subsection and has not voted in favor of or consented to
the merger or consolidation of the date that the merger or consolidation has
become effective; or

     (2) If the merger or consolidation was approved pursuant to (S) 228 or (S) 
253 of this title, each constituent corporation, either before the effective
date of the merger or consolidation or within ten days thereafter, shall notify
each of the holders of any class or series of stock of such constituent
corporation that are entitled to appraisal rights of the approval of the merger
or consolidation and that appraisal rights are available for any or all shares
of such class or series of stock of such constituent corporation, and shall
include in such notice a copy of this section; provided that, if the notice is
given on or after the effective date of the merger or consolidation, such notice
shall be given by the surviving or resulting corporation to all such holders of
any class or series of stock of a constituent corporation that are entitled to
appraisal rights. Any stockholder entitled to appraisal rights may, within
twenty days after the date of mailing of such notice, demand in writing from the
surviving or resulting corporation the appraisal of such holder's shares. Such
demand will be sufficient if it reasonably informs the corporation of the
identity of the stockholder and that the stockholder intends thereby to demand
the appraisal of such holder's shares. If such notice did not notify
stockholders of the effective date of the merger or consolidation, either (i)
each such constituent corporation shall send a second notice before the
effective date of the merger or consolidation notifying each of the holders of
any class or series of stock of such constituent corporation that are entitled
to appraisal rights of the effective date of the merger or consolidation or (ii)
the surviving or resulting corporation shall send a second notice to all such
holders on or within 10 days after such effective date; provided, however, that
if such second notice is sent more than 20 days following the sending of the
first notice, such second notice need only to be sent to each stockholder who is
entitled to appraisal rights and who has demanded appraisal of such holder's
shares in accordance with this subsection. An affidavit of the secretary or
assistant secretary or of the transfer agent of the corporation that is required
to give either notice that such notice has been given shall, in the absence of
fraud, be prima facie evidence of the facts stated therein. For purposes of
determining the stockholders entitled to receive such notice, each constituent
corporation may fix, in advance, a record date that shall be not more than 10
days prior to the date the notice is given; provided that, if the notice is
given on or after the effective date of the merger or consolidation, the record
date shall be the effective date. If no record date is fixed and the notice is
given prior to the effective date, the record date shall be the close of
business the next day preceding the day on which the notice is given.

     (e) within 120 days after the effective date of the merger or 
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise

                                     III-2
<PAGE>
 
     (j) The costs of the proceeding may be determined by the Court and taxed 
upon the parties as the Court deems equitable in the circumstances. Upon 
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no 
stockholder who has demanded his appraisal rights as provided in subsection (d) 
of this section shall be entitled to vote such stock for any purpose or to 
receive payment of dividends or other distributions on the stock (except 
dividends or other distributions payable to stockholders of record at a date 
which is prior to the effective date of the merger or consolidation); provided, 
however, that if no petition for an appraisal shall be filed within the time 
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in 
subsection (e) of this section or thereafter with the written approval of the 
corporation, then the right of such stockholder to an appraisal shall cease. 
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery 
shall be dismissed as to any stockholder without the approval of the Court, and 
such approval may be conditioned upon such terms as the Court deems just.

     (l) The shares of the surviving or resulting corporation to which the 
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation. (Last amended by 
Ch. 79, L. '95, eff. 7-1-95.)

                    INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
         -----------------------------------------

     As allowed by the California General Corporation Law, the Articles 
of Incorporation of Summa provide that the liability of the directors of Summa 
for monetary damages shall be eliminated to the fullest extent permissible under
California law. This is intended to eliminate the personal liability of a 
director for monetary damages in an action brought by or in the right of Summa 
for breach of a director's duties to Summa or its shareholders, except for 
liability for acts or omissions that involve intentional misconduct or knowing 
and culpable violation of law, for acts or omissions that a director believes to
be contrary to the best interests of Summa or its shareholders or that involve 
the absence of good faith on the part of the director, for any transaction from 
which the director derived an improper personal benefit, for acts or omissions 
that show a reckless disregard for the director's duty to Summa or its 
shareholders in circumstances in which the director was aware, or should have 
been aware, in the ordinary course of performing a director's duties, of a risk 
of serious injury to Summa or its shareholders, for acts or omissions that 
constitute an unexcused pattern of inattention that amounts to an abdication of 
the director's duty to Summa or its shareholder, with respect to certain 
contracts in which a director has a material financial interest, and for 
approval of certain improper distributions to shareholders or certain loans or 
guarantees. This provision does not limit or eliminate the rights of Summa or 
any shareholder to seek non-monetary relief such as an injunction or rescission 
in the event of a breach of a director's duty of care.

     Summa's Bylaws require Summa to indemnify its officers, directors, 
employees and other agents to the full extent permitted by law, including those 
circumstances in which indemnification would otherwise be discretionary. 
Insofar as indemnification for liabilities arising under the Securities Act of
1933 (the "Act") may be permitted to officers, directors or persons controlling
the Company pursuant to the foregoing provisions, the Company has been informed
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is
therefore unenforceable.

ITEM 22. UNDERTAKINGS
         ------------

     (1) Summa hereby undertakes as follows: that prior to any public 
reoffering of the securities registered hereunder through use of a prospectus
which is a part of this Registration Statement, by any person or party who is
deemed to be an underwriter within the meaning of Rule 145(c), Summa undertakes
that such reoffering prospectus will contain the information called for by the
applicable registration form with respect to reofferings by persons who may be
deemed underwriters, in addition to the information called for by the other
items of the applicable form.

     (2) Summa undertakes that every prospectus (i) that is filed pursuant to 
paragraph (1) immediately preceding, or (ii) that purports to meet the 
requirements of Section 10(a)(3) of the Securities Act and is used in connection
with an offering of securities subject to Rule 415, will be filed as a part of
an amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

     (3) Summa hereby undertakes to respond to requests for information that is 
incorporated by reference into the Joint Proxy Statement/Prospectus pursuant to
Items 4, 10(b), 11 or 13 of Form S-4, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to the request.

     (4) Summa hereby undertakes to supply by means of a post-effective 
amendment all information concerning a transaction, and the company being 
acquired involved therein, that was not the subject of and included in the 
Registration Statement when it became effective.

     (5) Insofar as indemnification for liabilities arising under the Act may 
be permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

     Re:  Common Stock of Summa Industries ("Summa") issuable
          to the stockholders of LexaLite International Corporation
          ("LexaLite") as a consequence of the Merger of a wholly-owned
          subsidiary of Summa with and into LexaLite
          -------------------------------------------------------------

Ladies and Gentlemen:

     We have acted as counsel to Summa Industries, a California corporation 
("Summa"), with respect to the proposed merger (the "Merger") of Charlevoix the 
Beautiful, Inc., a California corporation and wholly-owned subsidiary of Summa 
("Subsidiary"), with and into LexaLite International Corporation, a Delaware 
corporation ("LexaLite"). As a consequence of the Merger, shares of Summa's 
Common Stock (the "Shares") will be issued to the former stockholders of 
LexaLite on the terms and conditions set forth in the Agreement of Merger dated
November    , 1996 by and among Summa, Subsidiary and LexaLite. The Shares will
         ---
be registered under the Securities Act of 1933, as amended (the "Securities 
Act"), pursuant to Summa's Registration Statement on Form S-4 (the "Registration
Statement") which became effective under the Securities Act on October 17, 1996.

     As such counsel, we have made such legal and factual examinations and 
inquiries as we deemed advisable under the circumstances for the purposes of 
rendering this opinion, and in the course thereof, we have obtained from public 
officials such assurances as to factual matters as we considered necessary.

    On the basis of and relying upon the foregoing examinations and inquiries, 
we are of the opinion that the Shares, when issued by Summa as a consequence of 
the Merger in the manner and upon the terms contemplated by the Registration 
Statement, will be legally issued, fully paid and non-assessable.

     We hereby consent to the use of this opinion as an exhibit to the 
Registration Statement and to the reference to us under the caption "Legal 
Matters" in the Registration Statement.

                                     Very truly yours,

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

                     TERMS OF EMPLOYMENT -- JOSH T. BARNES

SUMMA INDUSTRIES, effective upon the consummation of the merger of Charlevoix
The Beautiful, Inc. with LexaLite, reconfirms Josh T. Barnes as a continuing
non-contractual "employment-at-will of LexaLite".  LexaLite retains its right to
terminate such employment at any time and Mr. Barnes retains the right to resign
at any time.  While both parties expect any termination of employment, by either
party, to recognize the many years of beneficial association in the manner,
notice and terms of such action, both, however, also acknowledge that the other
has no obligation to fulfill such expectation, except as stated herein.  A
separate Covenant Not-To-Compete and certain benefits, later addressed, do
survive termination of employment.

Mr. Barnes shall serve as Executive Director of LexaLite, in which role he will
report to the president of SUMMA INDUSTRIES.  In this capacity, Mr. Barnes will
perform the following duties: new business conceptualization; new product
conceptualization; mentoring to newer design employees; consultation to SUMMA
with respect to mergers and acquisition candidates; consultation to SUMMA and
its subsidiaries with respect to product development, manufacturing methods and
systems; and other such activities as shall from time to time be assigned.  Mr.
Barnes shall be reimbursed for all costs and expenses necessary to the
performance of his duties and shall be provided with suitable transportation.
He shall be salaried at sixty thousand dollars ($60,000) per year, subject to
annual review.  He shall receive fringe benefits in accord with the current
fringe benefit program in effect for LexaLite Officers.

Salary and fringes, other than Medical Benefits, shall continue only through the
first full month next  following termination of employment.  Medical benefits
(Hospitalization and Supplemental Medical) shall continue for five (5) years
after such termination.

An existing Covenant Not-To-Compete shall become effective as of the date of
termination and shall be modified to provide for consideration, payable to Mr.
Barnes, in the amount of fifteen thousand dollars ($15,000) per quarter, for
twenty (20) consecutive quarters.

In addition to a salary, Mr. Barnes shall be paid an incentive bonus based on
two (2.0) points for fiscal year 1997 and thereafter.  The bonus shall be paid
in accord with the then current Incentive Bonus Program and shall continue
though the final payment for the first full fiscal year subsequent to
termination of employment.

Agreed and Accepted, for himself,    Agreed and Accepted, for SUMMA INDUSTRIES,

     8.  This Covenant and the obligations of Barnes and LexaLite hereunder

been executed and delivered for value.

     9.  Barnes acknowledges and consents to the in personam jurisdiction and
venue of the Federal and State courts within the State of Michigan for purpose
of the enforcement of any provision of this Covenant.  Barnes agrees that any
suit hereunder may be brought in the Court for the Western District of Michigan,

Agreement dated September 17, 1993 and any other Covenant-Not-To-Compete
Agreement between Barnes and LexaLite, and shall become effective immediately
upon, and only upon, the consummation of the Merger.

                                                                    ------------
                        Design and Consulting Agreement

This Agreement, effective January 1, 1993 is by and between LexaLite 
International Corporation, a Delaware corporation, of U.S. 31, Charlevoix, 
Michigan 49720, hereinafter "LexaLite" and Business Activities Corporation, a 
Michigan corporation, of Post Office Box 244, Charlevoix, Michigan 49720, 
hereinafter "BAC".

WHEREAS LexaLite has a need for new product ideas and designs both in lighting 
and in other markets and also for optical design services relating to its 
lighting products, and for consulting services in research and development and,

WHEREAS BAC has outstanding optical design capabilities as confirmed by recent 
new product introductions by LexaLite and also has knowledge of non-lighting 
product research and development including, but not limited to, its own research
of a certain marine product of high potential but at high risk,

NOW THEREFORE, LexaLite and BAC do enter into this Design and Consulting 
Agreement and, further, do agree as follows:

     BAC shall increase Product development, both in lighting and in other 
   markets, for the exclusive benefit of LexaLite.
     BAC shall dedicate its limited optical design capability exclusively to 
   LexaLite and shall do such designs without compensation other than the fees 
   agreed to herein, unless such workload requires additional design assistance.
     BAC shall grant LexaLite exclusive rights to each new design or Product. 
   Those rights shall include trade secrets, copyright and patent 
   opportunities, as such may be created. All costs relating to such 
   intellectual property shall be to the account of LexaLite.
     In consideration of these services to be provided to LexaLite by BAC, 
   LexaLite shall pay BAC a flat fee of twenty five hundred dollars ($2,500) per
   month, payable on, or about, the first of each month. (Note: these parties
   contemplate entering into a separate contract that will enable BAC to
   participate in the rewards of high margin products as they achieve successful
   production.)

This Agreement shall be for the Calendar Year 1993 and shall automatically be 
extended for an additional one year term on the first day of each year 
thereafter. It may be terminated without cause by either party on one year's
written notice and for proper cause, without other notice if a written notice of
default shall not be remedied within thirty days after being served.

Disputes arising hereunder shall be submitted to the firm of Pointner & Joseph 
for adjudication (non-binding). This Agreement is subject to the laws and courts
of the State of Michigan. Nothing herein shall be construed as creating any 
employer/employee relationship and BAC may substitute persons and schedule times
and work locations at its own discretion.

         Signed, in agreement hereto, this 17th day of September, 1993
                                           ----

             Product Introduction and Market Development Contract
                               Page 1 of 3 Pages

THIS CONTRACT, made and effective this 20th day of February, 1993, is by and 
between LexaLite International Corporation, a Delaware corporation, of U.S. 31, 
Charlevoix, Michigan 49720, hereinafter "LexaLite" and Business Activities 
Corporation, a Michigan corporation, of Post Office Box 244, Charlevoix, 
Michigan 49720, hereinafter "BAC".

     WHEREAS LexaLite has many new products both in lighting and in new markets 
such as, but not limited to, marine products, and is desirous of obtaining 
representation and professional services relating to the introduction and 
acceptance of such new products in their respective markets and,

     WHEREAS BAC has a working knowledge of all such new products of LexaLite 
and also has knowledge of the Lighting and Marine markets and further has 
established contacts with the buyers and the specifying influences within those 
two markets as well as in others and,

     WHEREAS LexaLite and BAC have a separate Design/Development Contract 
covering new product design and development as well as optical designs of 
lighting components and which existing contract is satisfactory to both parties.

     NOW THEREFORE, LexaLite and BAC do agree to hold the existing 
Design/Development Contract separate, in all respects, from this Product 
Introduction and Market Development Contract and do further agree to the 
definitions and terms of this contract, as follows:

     DEFINITIONS:
<TABLE> 
<CAPTION> 
  <C>              <S>
     Margin        The sales Margin as presently calculated by LexaLite. (Actual
                   selling price less manufacturing cost of goods sold. The cost
                   of goods sold does not include Selling, G & A, or Other
                   Expenses.) If LexaLite's method of calculating Margin be
                   changed, the Margins of Schedule A must also be changed to
                   maintain the same effect as if the present method of
                   calculation had remained unchanged.

     Objective     To introduce and thereafter increase market specifications
                   and acceptance of those LexaLite Products included in
                   Schedule A.

     Product(s)    A product included in this contract by listing in an attached
                   Schedule A; initially all 800 Series Reflexors(R), lenses 
                   and enclosures.

     Service(s)    Any services, technical assistance, specification work or
                   other effort provided by BAC, either to, or on behalf of,
                   LexaLite, toward achievement of the objective.

             Product Introduction and Market Development Contract
                               Page 2 of 3 Pages

     IT IS AGREED:

1.  BAC shall make diligent but reasonable efforts to increase both acceptance
    and specification of the existing Products of LexaLite that have been
    introduced in recent years and are listed on attached original Schedule A.

2.  BAC shall assist LexaLite in introducing and obtaining specification and
    market acceptance of new Products, as each are added to the listing on the
    then revised Schedule A.

3.  Efforts to achieve the Objective shall include BAC furnishing Services (such
    as technical expertise) to LexaLite without hourly or other compensation
    charges, provided, such expertise or skills are available. A request, by
    LexaLite, for Services to be provided at a remote location shall authorize
    related reasonable and proper expenses necessary to the providing of such
    Services.

4.  In consideration of its efforts, LexaLite shall pay BAC a commission on the
    sales of all Products. The initial commission schedule is attached, hereto,
    as Schedule A, and includes existing and future 800 Series reflectors,
    refractors, lenses and enclosures.

5.  New products of LexaLite that result from the separate and earlier
    referenced Design/Development Contract, shall automatically be added to
    Schedule A as each becomes production. LexaLite may, at its option, add
    other products or lines of products to Schedule A if it desires BAC Services
    for that product or line of products. Products shall become non-
    commissionable when the Margin on said Product drops below the minimum
    specified for that Product. If the Margin subsequently improves to the
    minimum, the Product shall again become commissionable. Products may be
    removed from Schedule A only with the written consent of both parties.

6.  Commissions under Schedule A shall be payable not later than the twentieth
    day of each month on the sales of covered Products shipped during the
    preceding month. Should any trade payable created on the sale(s) of covered
    Products with normal thirty day terms remain unpaid for ninety days,
    LexaLite shall debit BAC and deduct the amount of the commission previously
    paid on subject unpaid sale(s) from the next commission payment made to BAC.
    (If the payable is subsequently received, the amount deducted shall then be
    repaid.)

7.  Commissions are payable for the useful life of each Product but only while
    that Product enables a premium price such that the sales Margin equals a
    specified minimum percentage of thirty percent (30%) if none is specified. A
    Product falling below that, such as during the peak of its volume cycle, may
    again be commissionable as its Margin increases on the back side of the
    volume cycle. Products on Schedule A may have unique commission schedules.
    Any 800 Series Product, for example, is commissioned at 1 1/2% if its Margin
    is greater than 35%, at 1% if its Margin is greater than 30% but less than
    35%, and not commissioned if its Margin less than 30%.

                               Page 3 of 3 Pages

8.  In view of the high cost of the initial efforts and the long term nature of
    the return on that investment, both parties agree that this contract must be
    of long duration and not subject to cancellation subject to the following
    four exceptions:

     (I)    no further commissions are due and none have been payable for a
            period of twelve consecutive months, in which event the contract
            terminates.

     (II)   BAC provides no Services or Products for twelve (12) consecutive
            years, in which event LexaLite may terminate the contract without
            further obligation upon payment, in full, of all commissions then
            payable.

     (III)  either party defaults under its obligations and, having received
            notice of such default, has refused or been unable to remedy such
            default. Disputes arising hereunder shall be submitted to the firm
            of Pointner & Joseph for adjudication (non-binding). Should the
            dispute remain unresolved, an injured party shall be entitled to
            take any action proper under the laws of the State of Michigan
            including action to recover damages before an appropriate Court in
            and for Charlevoix County.

     (IV)   by mutual written consent of the parties hereto.

Disclaimer: Neither BAC nor LexaLite is the agent or employee of the other. 
Neither BAC nor LexaLite may make commitments binding on the other, BAC may not 
accept orders or furnish prices on behalf of LexaLite, except where a quotation 
has been furnished to BAC by LexaLite. Nothing herein shall be construed to 
create any relationship other than a contractual relationship for commission 
payments on future named product sales in consideration for technical and 
promotional services on behalf of those named products.

     This contract has been revised and this revision is hereby ratified on 17th
                                                                            ----

                   Accessories sold separately are also included but are
                   probably not commissionable as the Margin on such will
                   typically be below the minimum that is commissionable. The
                   selling price of accessories costed as part of an assembly
                   and the selling price of any assembly labor or other items
                   costed therein, including packaging, are also commissionable
                   if included in a package selling price but only if the
                   resulting Margin of the entire package is still sufficient to
                   equal the minimum (or a higher level) commission rate,
                   despite the lower margin inclusions.

or threatened violation hereof, in addition to such other relief as may be

                        EXCLUSIVE DISTRIBUTOR AGREEMENT
                        -------------------------------

     WHEREAS LexaLite International Corporation, located in Charlevoix, 
Michigan, (hereinafter referred to as "LEXALITE") wishes to obtain a distributor
to promote the use and handle the sales of its products in the Asian and South 
Pacific markets, and

     WHEREAS Austrasia Banking Corporation, with United States offices located 
in Charlevoix, Michigan, (hereinafter referred to as "AUSTRASIA") is desirous of
becoming an exclusive distributor of LexaLite products in that market place,

     NOW THEREFORE, these two parties enter into this Agreement, which shall 
become effective July 1, 1979.

     IT IS AGREED:

        I. That LEXALITE does herewith appoint AUSTRASIA sole and exclusive
           distributor for LEXALITE Products, materials, or services to the
           territory described below.

       II. That the territory shall consist of Eastern Asia and the South
           Pacific, specifically defined as all market places lying west of the
           International Date Line, south of the 45th N. parallel and east of 
           the 70 degrees E. meridian.

      III. That AUSTRASIA shall purchase and LEXALITE shall sell its products,
           materials and services at mutually agreeable prices which typically
           shall be 10% below any published list price. On open stock products,
           price shall be maximum discount less 10%. Participation products
           shall be at maximum participation level but without additional
           discount. Certain products, such as the 297 Series shall not carry a
           full discount. AUSTRASIA shall pay for all such purchases on terms
           of net 45 days except as otherwise mutually agreed.

       IV. That LEXALITE shall refer any and all orders or inquiries received
           from within the described territory to AUSTRASIA and shall not make 
           direct sales to points within the territory.

        V. That AUSTRASIA shall restrict its sales of LEXALITE proprietary
           products to original equipment manufacturers; this restriction shall
           not apply to LEXALITE services, materials or custom molded products.

       VI. That in consideration of the most favorable pricing offered to
           AUSTRASIA by LEXALITE; AUSTRASIA shall accept all credit risks and
           shall be liable for payment of any LEXALITE products, materials, or
           services purchased by AUSTRASIA regardless of its customers failure
           to pay.

      VII. That this agreement shall remain in effect for a period of three
           years and shall automatically be renewed for a like period on July 1,
           1982, and on each subsequent third anniversary thereof unless
           terminated as provided herein.

     VIII. That either party may terminate this Agreement without cause by
           notice to that effect in writing by registered or certified mail not
           less than six months prior to the end of the then current three year
           term; in which event the Agreement shall terminate at the end of that
           term and there shall be no further obligation of either party unto 
           the other except for payment(s) for products, materials or services
           previously rendered or delivered and for which a payable exists under
           the terms of this Agreement.

<PAGE>
 
     IX. That either party may terminate this Agreement for cause by notice to
         that effect in writing by registered or certified mail, stating the
         cause or reason for terminating, given not less than 90 days prior to
         effective date of such termination. On receipt of such notice, the
         other party shall have 60 days in which to remedy the cause or reason
         stated; and if the remedy is satisfactory to the first party, the
         termination notice shall be cancelled. If the other party is unable to
         remedy to the satisfaction of the first party, this Agreement shall
         terminate at midnight on the 90th day following the delivery of said
         notice as evidenced by the delivery receipt for the certified or
         registered notice. The same restriction on further obligation as stated
         in Paragraph VIII shall then apply.

      X. That nothing herein shall act to restrain either party from the normal
         trade in which each is engaged; but it shall instead act to encourage a
         mutually beneficial supplier/distributor relationship also working to
         the benefit of the customer within the described territory by providing
         concentrated and better coverage of the market place at competitive
         prices.

     THIS AGREEMENT is the entire Exclusive Distributor Agreement between the 
two parties hereto and no other Agreements are expressed or implied.

after each Valuation Date, the Administrator shall credit each Participant's
accounts other than Employer Stock Accounts with the proportion of the net
earnings of such accounts and of the net gain from the disposition of assets of
such accounts since the last Valuation Date, as the balance of each such account
bears to the aggregate balances of all such accounts before allocations of
contributions and forfeitures; and shall charge each such account with any net
loss suffered by the trust since the last Valuation Date, and any expenses paid
from the trust since the last Valuation Date, and any expenses paid from the
trust, in the same proportion and manner as earnings and gains are credited to
those accounts.  Interest paid under an installment contract for the purchase of
Employer Stock or on an Exempt Loan used to purchase Employer Stock shall not be
deemed an expense under this provision.

     (b)  Revaluation of Trust.
          ----------- -- ----- 

          (i) Employer Stock.  As soon as administratively feasible after each
              -------- -----

Employer Stock and shall certify to the Trustee the Fair Market Value.  The
Trustee shall thereupon adjust its records to reflect Fair Market Value.
Determination of Fair Market Value shall be made in good faith and in accordance
with this plan and with Regulations under ERISA Section 3(18).  Fair Market
Value of Employer Stock acquired after December 31, 1986, shall be determined

              ----- --------
Trustee shall revalue, at fair market value, the assets of the trust other than
the Employer Stock held in the Employer Stock Accounts.  The amount in each
account other than the Employer Stock Account shall be adjusted as of the

the total assets of all such accounts equals the ratio of the amount in the
account before adjustment to the total assets of all such accounts before
adjustment.

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

         ---- -- -------- -----                                            
will be debited with the Participant's share of Employer Stock (including
fractional shares) sold by the trust from that account for any reason.  The
proceeds received from the sale shall be credited directly to the Participant's
Other Investments Account.  If unallocated Employer Stock is sold, the proceeds,
as necessary, shall be used to repay, or prepay, the Exempt Loan by which such
stock was purchased.  After payment of the Exempt Loan, if additional proceeds
from the sale of such Employer Stock remain, the proceeds shall be considered
earnings and gains of the trust on ESOP Accounts, and shall be allocated in the
proportion that the Employer Stock in the Participant's Employer Stock Account
with respect to that Exempt Loan bears to the aggregate Employer Stock in all
Participant's Employer Stock Accounts with respect to that Exempt Loan.

     (b) Purchase of Employer Stock.  If the Trustee purchases Employer Stock
         -------- -- -------- -----                                          
with cash rather than with the proceeds of an Exempt Loan, each Participant's
Other Investments Account will be debited with the Participant's share of the
purchase price for Employer Stock purchased by the trust, and the shares
purchased (including fractional shares) shall be credited directly to the
Participant's Employer Stock Account.

involving Employer Stock, including, but not limited to, its distribution as a
benefit and its repurchase or sale, are subject to and conditioned upon
compliance with applicable provisions of federal and state securities laws or
regulations.  Without limiting the preceding sentence, no certificate for shares
of Stock shall be transferred to a Participant or Beneficiary unless the shares,

of an exempt transaction, or are registered within the meaning of applicable
federal or state securities laws and regulations; and (ii) comply with the rules
of any stock exchange on which the Employer's shares may be listed.  Unless an
exemption from registration is available, prior to or as soon as practicable
after the time when shares of Employer Stock would otherwise be deliverable to a
Participant or Beneficiary, the Employer will register the shares or interest,
as required under federal and/or state law.  If the shares are delivered to
Participant or Beneficiary pursuant to a registration exemption, the Participant
or Beneficiary shall deliver to the Employer a representation in writing signed
by the Participant or the Participant's representative, or by the Beneficiary,
as the case may be, that the Employer Stock will be held indefinitely unless it
is subsequently registered under state and federal law, or unless an exemption
from the registration is available.  A stock certificate issued by the Employer
pursuant to a registration exemption shall bear a legend and statement that the
Employer deems advisable to assure compliance with this plan and with federal
and state laws and regulations that shall be in substantially the form set forth
in (e) below.

     (e) Stock Certificate Legend.  Benefit share certificates of Employer
         ----- ----------- ------

     REPRESENTED BY THIS CERTIFICATE.


7.12  Distribution of Cash Dividends.
      ------------ -- ---- --------- 

      If an Exempt Loan used to purchase Employer Stock is not fully repaid,
cash dividends on Employer Stock purchased with the proceeds of that Exempt Loan
will be used to repay such Exempt Loan. If the Exempt Loan used to purchase the
Employer

                                     -39-

<PAGE>
 
Stock has been repaid or the cash dividends are not used to repay the Exempt
Loan, the Trustee shall distribute cash dividends paid on the Employer Stock
allocated to a Participant's account directly to the Participant. Cash dividends
paid on Employer Stock which was not purchased with an Exempt Loan may be
distributed directly to the Participant. Cash dividends to be distributed to
Participants shall be so paid not later than 90 days after the end of the Plan
Year during which they were paid to the trust.

     (e) Securities Acquisition Loan.  "Securities Acquisition Loan" means any
         ---------- ----------- ----                                          
loan that meets the requirements of Code Section 133.

     (f) Unallocated and Pledged Employer Stock.  The Employer Stock shall be
         ----------- --- ------- -------- -----                              
maintained in a suspense account, if not pledged as collateral, and shall be
released from the suspense account or, if pledged as collateral, shall be
released from encumbrance as provided in (i) below.

     (g) No Recourse.  Under the terms of an Exempt Loan, the creditor shall be
         -- --------                                                           
given no recourse against the trust, except with respect to the collateral
pledged.

     (h) Repayment of Loan.  An Exempt Loan shall be repaid solely from
         --------- -- ----                                             
Employer Contributions (other than contributions in the form of Employer Stock)
and forfeitures, proceeds from the sale of unallocated shares of Employer Stock
purchased with the Exempt Loan, and from trust earnings on such contributions or
on the Employer Stock purchased with such Exempt Loan, and the Employer
Contributions shall be sufficient to enable the trust to pay each and every
installment of principal and interest when due, even if no tax benefit results
from the contributions.

     (i) Release of Pledged Employer Stock.  An Exempt Loan must provide that
         ------- -- ------- -------- -----                                   
upon payment of a portion of the balance due, the creditor shall release a Pro
Rata Portion of the pledged collateral or, if not pledged as collateral, a Pro
Rata Portion of the Employer Stock shall be released from the suspense account,
as the Exempt Loan is paid.  Employer Stock purchased with each Exempt Loan
shall be released separately.

         (i)  Pro Rata Portion.  "Pro Rata Portion"  means the number of pledged
              --- ---- -------                                                  
securities or number of shares in the suspense account held immediately before
release for the current Plan Year multiplied by a fraction.  The numerator of
the fraction is the amount of principal and interest paid during the Plan Year
and the denominator is the sum of the numerator and the remaining principal and
interest to be paid under the obligation in all future years.  The number of
future years shall be determined without taking into account possible extensions
or renewals of the obligation.  If the interest rate under the obligation is
variable, the interest to be paid in future years shall be computed by using the
interest rate applicable as of the end of the current Plan Year.  If the
collateral or suspense account includes more than one class of Employer Stock,
the number of shares of each class to be released for a Plan Year must be
determined by applying the same fraction to each class.

         (ii) Alternative Determination of Pro Rata Portion. At the direction of
              ----------- ------------- -- --- ---- -------
the Administrator, Pro Rata Portion of securities may be determined with
reference

                                     -51-

<PAGE>
 
solely to principal payments, but only if (A) the obligation provides for annual
payments of principal and interest at a cumulative rate that is not less rapid
at any time than level annual payments of the amounts for 10 years, and (B) the
interest included in any payment is disregarded only to the extent that it would
be determined to be interest under standard loan amortization tables. This
alternate determination shall not be applicable from the time that, by reason of
a renewal, extension, or refinancing, the sum of the expired duration of the
obligation, plus any renewal period, extension period, or the duration of a new
obligation used to refinance the existing obligation, exceeds 10 years.

         (iii)  Special Release Rule. Notwithstanding (i) and (ii) above, to the
                ------- ------- ----
extent provided in Section 5.2(a)(ii)(C), at the direction of the Employer, the
Trustee shall release additional shares of Employer Stock for purposes of
allocation to Participant accounts.

     (j) Pending Investment.  Pending investment in Employer Stock, funds may
         ------- ----------                                                  
be invested and reinvested pursuant to Section 9.2.


9.5  Purchase From Stockholder.
     -------- ---- ----------- 

     As directed by the Administrator, the Trustee shall enter into a buy-sell
agreement or agreements under the terms of which the Trustee agrees to purchase
the Employer Stock of a stockholder who is a party to the agreement.  A buy-sell
agreement shall provide that the price to be paid by the Trustee for the
Employer Stock shall not exceed the fair market value of the Employer Stock.
The Trustee may not enter into a buy-sell agreement to become effective upon the
death of the stockholder, or at some other future indefinite time.


9.6  Stock Dividends, Stock Splits, Etc.
     ----- ---------  ----- ------  --- 

     Employer Stock received by the Trustee as a stock dividend or stock split
or as the result of a reorganization or other recapitalization of the Employer
shall be allocated under Section 5.4.  If any rights, warrants, or options are
issued on Employer Stock held in the trust, the Trustee may exercise them for
the acquisition of additional shares of Employer Stock to the extent cash is
then available.  Employer Stock acquired in this manner shall be treated as
Employer Stock bought by the Trustee for the net price paid.  If any rights
warrants, or options on Employer Stock that are not exercised shall be sold by
the Trustee, the proceeds shall be treated as a current cash dividend received
on Employer Stock.

it is intended that a Securities Acquisition Loan used to acquire stock after
July 9, 1989, qualifies for the exclusion of interest from the lender's gross

acquired with or transferred to this plan in connection with the Securities
Acquisition Loan, and allocated to the Participant's account, shall be voted

   This is an amendment by LexaLite International Corporation ("Employer").


                             W I T N E S S E T H:
                             - - - - - - - - - - 

         WHEREAS, LexaLite International Corporation amended and restated the 
LexaLite International Corporation Amended and Restated Employee Stock Ownership
Plan ("plan") on August 8, 1994, effective July 3, 1989; and

         WHEREAS, to remain qualified under Code Section 401(a), the plan must
be amended to incorporate changes required or permitted by amendments to the
Internal Revenue Code and as provided in certain IRS Revenue Procedures;

         NOW, THEREFORE, the Employer amends the plan as follows:

ONE.     To incorporate the reduced compensation limit under Code Section 401(a)
- ---      (17), the following model language from IRS Revenue Procedure 94-13 is
         adopted, effective January 1, 1994, thereby superseding the
         corresponding provisions of the plan:

         In addition to other applicable limitations set forth in the plan, and
notwithstanding any other provision of the plan to the contrary, for Plan Years
beginning on or after January 1, 1994, the annual Compensation of each Employee
taken into account under the plan shall not exceed the OBRA '93 annual 
compensation limit.  The OBRA '93 annual compensation limit is $150,000, as
adjusted by the Commissioner for increases in the cost of living in accordance 
with Section 401(a)(17)(B) of the Internal Revenue Code.  The cost-of-living 
adjustment in effect for a calendar year applies to any period, not exceeding 12
months, over which Compensation is determined (determination period) beginning 
in such calendar year.  If a determination period consists of fewer than 12 
months, the OBRA '93 annual compensation limit will be multiplied by a fraction,
the numerator of which is the number of months in the determination period, and
the denominator of which is 12.

         For Plan Years beginning on or after January 1, 1994, any reference in
this plan to the limitation under Section 401(a)(17) of the Code shall mean the
OBRA '93 annual compensation limit set forth in this provision.

      WHEREAS, LexaLite International Corporation amended and restated the 
LexaLite International Corporation Amended and Restated Employees Stock 
Ownership Plan ("plan") on August 8, 1994, effective July 3, 1989, and 
subsequently amended the plan by an instrument dated October 25, 1994; and

      WHEREAS, the Employer wishes to correct an omission in the amendment and 
restatement of the plan;

      NOW, THEREFORE, the Employer amends the plan, effective July 3, 1989, as
follows:

ONE.  The first paragraph of Section 5.2(a)(iii)(A) is amended to read:
- ---
           (A)  Participating Compensation.  "Participating Compensation"
                ------------- ------------
means the Participant's Compensation for services in Covered Employment during a
Plan Year.

TWO.   Section 5.2(a)(iii)(B) is amended to read:
- ---
           (B)  Compensation.  "Compensation" means an Employee's W-2 wages as
                ------------ 
provided in Regulations under Code Section 415 plus Elective Deferrals and any 
amount that is excluded from gross income pursuant to Code Section 125; but 
excluding, whether or not includable in income, reimbursements or other expense 
allowances, cash and noncash fringe benefits, moving expenses, deferred 
compensation, welfare benefits, and any amounts paid to a Highly Compensated 
Employee attributable to the LexaLite International Stock Incentive Award 
Program.  "Elective Deferrals" means the elective contributions made for the 
Participant and any other portion of the Participant's income deferred and 
excluded from current taxation under Code Section 402(e)(3) (a cash or deferred 
401(k) profit-sharing plan); 402(h) (a simplified employee pension plan); or 
403(b) (a tax-sheltered annuity).
