To the Shareholders of
Summa Industries:

  NOTICE IS HEREBY GIVEN that the Annual Meeting of Shareholders (the "Annual
Meeting") of Summa Industries, a California corporation (the "Company"), will be
held on January 26, 1998 at 10:00 a.m., local time, at the Marriott Hotel, 3635
Fashion Way, Torrance, California (near the southeast corner of Hawthorne and
Torrance Boulevards, behind the Computax Building), for the following purposes:

  1.  to approve the proposed reincorporation of the Company from the State of
  California to the State of Delaware, including separate proposals to provide
  for the following in the Company's proposed Delaware certificate of
  incorporation: (a) elimination of the shareholders' ability to call a special
  meeting of the shareholders; and (b) requirement of a supermajority vote (66-
  2/3%) of the shareholders to amend certain provisions of the Company's
  proposed Delaware certificate of incorporation and bylaws;

  2.  to approve a proposed amendment of the Company's 1995 Stock Option Plan to

                         ANNUAL MEETING OF SHAREHOLDERS
                         To Be Held on January 26, 1998


                                  INTRODUCTION

  This Proxy Statement and the accompanying form of proxy are being sent to
shareholders of Summa Industries, a California corporation ("Summa" or the
"Company"), on or about December 10, 1997.  The accompanying proxy is solicited
by and on behalf of the Board of Directors of the Company for use at the Annual
Meeting of Shareholders (the "Annual Meeting") of Summa to be held on January
26, 1998 at 10:00 a.m., local time, at the Marriott Hotel, 3635 Fashion Way,
Torrance, California, and at any adjournments and/or postponements thereof.

  All expenses associated with soliciting proxies, including the preparation,
assembly, printing and mailing of this Proxy Statement, will be borne by the
Company.  It is contemplated that proxies will be solicited principally through
the use of the mail, but officers, directors and employees of the Company may
solicit proxies personally or by telephone or facsimile, without receiving
additional compensation therefor. The Company will reimburse banks, brokerage
houses and other custodians, nominees and fiduciaries for their reasonable
expenses in forwarding these proxy materials to their principals.

                                  RECORD DATE
                                        
  Shareholders of Summa Common Stock of record at the close of business on
December 5, 1997 (the "Record Date") are entitled to notice of and to vote on
all matters presented at the Annual Meeting and at any adjournments and/or
postponements thereof.  On the Record Date, there were 4,119,384 shares of
Common Stock outstanding, held by 500 shareholders of record and an estimated
600 additional beneficial owners.

                                VOTING; PROXIES
                                        
  The presence, either in person or by proxy, of persons entitled to vote a
majority of the outstanding shares of Common Stock is necessary to constitute a
quorum for the transaction of business at the Annual Meeting and at any
adjournments and/or postponements thereof.  On each matter to be considered at
the Annual Meeting, shareholders will be entitled to cast one vote for each
share of Common Stock held on the Record Date.  In accordance with the Company's
Restated Articles of Incorporation, there will be no cumulative voting for the
election of directors.

  Approval of Proposals 1 and 3 will require the affirmative vote of a majority
of the Company's outstanding shares that are entitled to vote.  For purposes of
Proposals 1 and 3, abstentions and broker non-votes (i.e. where the broker or
nominee submits a proxy specifically indicating a lack of discretionary
authority to vote on a matter)  will be counted for purposes of determining the
presence or absence of a quorum.  However, because approval of Proposals 1 and 3
will require the affirmative vote of a majority of the Company's outstanding
shares which are entitled to vote, abstentions and broker non-votes will have
the same effect as a vote against Proposals 1 and 3.  Approval of Proposal 2
will require the affirmative vote of a majority of the Company's shares present
and voting at the Annual Meeting, provided the number of shares present or
represented constitutes a quorum.  For Proposal 4, the seven director nominees
receiving the highest number of votes at the Annual Meeting with a quorum
present

<PAGE>
 
or represented will be elected. Abstentions and broker non-votes on Proposals 2
and 4 will be counted for purposes of determining the presence or absence of a
quorum, but will not constitute a vote "for" or "against" either such Proposal
and will be disregarded in calculating the votes cast as to each such Proposal.

  SHAREHOLDERS ARE URGED, WHETHER OR NOT THEY EXPECT TO ATTEND THE ANNUAL
MEETING, TO COMPLETE, SIGN AND DATE THE ACCOMPANYING PROXY CARD AND RETURN IT
PROMPTLY IN THE ENCLOSED ENVELOPE.  Properly executed and returned proxies,
unless revoked, will be voted as directed by the shareholder, or, in the absence
of such direction, by the persons named therein FOR approval of each proposal
and FOR election of each director nominee set forth herein in accordance with
the recommendation of the Board of Directors, and in the proxy holders'
discretion as to other matters that may properly come before the Annual Meeting.
A proxy may be revoked at any time before it is voted by delivery of written
notice of revocation to the Secretary of the Company, or by delivery of a
subsequently dated proxy, or by attendance at the Annual Meeting and voting in
person.  Attendance at the Annual Meeting without also voting will not in and of
itself constitute the revocation of a proxy.

                        PROPOSAL NOS. 1, 1(A) AND 1(B)
                    REINCORPORATION IN THE STATE OF DELAWARE
                             AND RELATED PROPOSALS


General

  The Board of Directors has unanimously approved and, for the reasons described
below, recommends that the shareholders of the Company approve a reorganization
in which the Company's state of incorporation would be changed from California
to Delaware.  This change would be accomplished by merging the Company (referred
to in this Proposal 1 as "Summa California") into a wholly-owned Delaware
subsidiary (referred to in this Proposal 1 as "Summa Delaware") newly formed for
this purpose, with each share of Summa California's Common Stock being exchanged
for one share of Common Stock of Summa Delaware.  Upon completion of the merger,
all of the previously outstanding shares of Common Stock of Summa California
will be automatically converted into shares of Common Stock of Summa Delaware.
The proposed reorganization will be accomplished pursuant to the terms and
conditions of an Agreement and Plan of Merger to be entered into between Summa
Delaware and Summa California, a copy of which is attached to this Proxy
Statement as Appendix I.
             ---------- 

  At and after the effective time of the merger, each certificate that
previously represented shares of Common Stock of Summa California will be deemed
for all purposes to evidence the right to receive the same number of shares of
Common Stock of Summa Delaware into which those shares of Common Stock of Summa
California have been converted.   IT WILL NOT BE NECESSARY FOR SHAREHOLDERS OF
                                          ---                                 
SUMMA CALIFORNIA TO HAVE THEIR STOCK CERTIFICATES EXCHANGED FOR STOCK
CERTIFICATES REPRESENTING SHARES OF SUMMA DELAWARE.  The Common Stock of Summa
California is qualified for trading on The Nasdaq National Market under the
symbol "SUMX," and after the reincorporation, Summa Delaware's Common Stock will
continue to be traded on The Nasdaq National Market under the same symbol.  The
reorganization will not result in any change in the name, business, management,
assets, liabilities or net worth of the Company.  Summa Delaware will be
governed by Delaware law and a new certificate of incorporation and bylaws,
which will result in certain changes in the rights of shareholders.  See
"Changes in Summa's Charter to be Effected by Reincorporation" and "Certain
Differences in State Corporation Laws" below.

  Shareholders should note that approval of the proposed reorganization will
constitute (a) approval of the assumption of Summa California's existing stock
option plans and outstanding stock options by Summa Delaware and (b) approval of
the certificate of incorporation and bylaws of Summa Delaware in substantially
the forms attached to this Proxy Statement as Appendix II and Appendix III,
                                              -----------     ------------ 
respectively; provided that, certain provisions in the certificate of
incorporation require separate approval of the Company's shareholders or such
provisions will not be included therein (see Proposals 1(a) and 1(b) below).
Furthermore, the proposed Summa Delaware certificate of incorporation provides
that the Summa Delaware board of directors shall be divided into three classes,
with each class of directors serving staggered three-year terms.  Therefor, if
the reorganization is approved, and assuming approval of Proposal 3 below, the
Company's two-class, seven-member Board of Directors would be modified upon
consummation of the reincorporation by dividing the four members of Class II
into two classes of two members each (see Proposal 4 "Composition of Classified
Board" below for additional information).

  The affirmative vote of the holders of a majority of the outstanding shares of
Summa California Common Stock entitled to vote will be required to approve the
Agreement and Plan of Merger.  If approved by the shareholders, it is
anticipated that the reorganization would be completed within sixty days of
shareholder approval.  However, the reorganization may be delayed or abandoned,
either before or after shareholder approval, if circumstances arise which, in
the opinion of the Board of Directors, make it inadvisable to proceed.  If the
reorganization is approved, the Company presently intends to complete the
reincorporation even if the shareholders of the Company do not approve either or
both of Proposals 1(a) and 1(b) below.

  Certain important aspects of the reorganization and reincorporation of the
Company in Delaware are outlined below.

                                       3

Dissenters' Rights of Appraisal

  Under California law, shareholders have the right, in some circumstances, to
dissent from certain corporate reorganizations and receive cash for their shares
at their "fair market value."  However, California law does not permit
dissenters' rights in connection with the type of reorganization presently
proposed by the Company and described herein.

Principal Reasons for the Reincorporation and Related Proposals

  The Board of Directors believes the change of domicile to be in the best
interests of the Company and its shareholders for several reasons.  Principally,
the Board of Directors believes that Delaware offers a more favorable and "user-
friendly" corporate environment for the efficient operation of a business,
particularly a business involved in mergers and acquisitions.  In the recent
acquisition of Calnetics Corporation ("Calnetics"), management of the Company
incorporated a wholly-owned subsidiary that was merged into Calnetics in
Delaware after being informed that such incorporation and subsequent merger in
California would involve additional filings (including tax clearance), time and
expense.  For many years Delaware has followed a policy of encouraging
incorporation in that state, and, in furtherance of that policy, has adopted
comprehensive, modern and flexible corporate laws which are periodically updated
and revised to meet changing business needs.  As a result, many major
corporations are now incorporated in Delaware and, in recent years, a number of
major public companies have obtained approval from their shareholders to
reincorporate in Delaware.  In fact, one of the Company's subsidiaries, LexaLite
International Corporation, reincorporated from Michigan to Delaware several
years before its acquisition by the Company for similar reasons.

  Reincorporation in Delaware will allow the Company the increased flexibility
and predictability afforded by Delaware law.  The Delaware Legislature is
particularly sensitive to issues regarding corporate law and is especially
responsive to developments in modern corporate law.  The Delaware courts have
developed considerable expertise in dealing with corporate issues, and a
substantial body of case law has developed construing Delaware law and
establishing public policies with respect to corporate legal affairs.  As a
result of these factors, it is anticipated that Delaware law will provide
greater predictability in the Company's legal affairs that is presently
available under California law.

  Another principal reason for the proposal by the Board of Directors to
reincorporate the Company in Delaware is that Delaware law permits the
classification of a seven-member board of directors into three classes, and such
classification is not permitted under California law with fewer than nine
members.  With the recent retirement of Messrs. Palmaer and Morehouse from the
Board of Directors, the Board has not identified suitable replacements for such
gentlemen, and does not believe that replacement is necessary or desirable at
this time.  In recent years, the size of the Board of Directors has increased,
due in part to acquisitions consummated by the Company with the former chief
executive of the acquired company thereafter joining the Board of Directors.
The Board of Directors does not believe that nine members are necessary to fully
and accurately analyze issues presented and to thoroughly debate the merits of
such issues, and believes that a Board of Directors consisting of seven members
will be of sufficient size and experience to manage the Company in an
appropriate manner at less expense than with nine members (see Proposals 3 and 4
below).  Nonetheless, the Board of Directors desires to have its membership
classified into three classes, a classification not permitted under California
law with less than nine members.  For further discussion, see "Certain
Differences in State Corporation Laws - Classified Board of Directors."

  The interests of the Board of Directors and management of the Company in
recommending and voting for the reincorporation proposal and related proposals
may not be the same as those of unaffiliated shareholders.  Delaware law does
not afford minority shareholders some of the rights and protections available
under California law (although, for example, the Company has already eliminated
the right to cumulative voting for directors with prior shareholder approval).
A discussion of the principal differences between California and Delaware law as
they affect shareholders is set forth in "Changes in Summa's Charter to be
Effected by Reincorporation" and "Certain Differences in State Corporate Laws"
below.

  The principal changes effected by the Delaware reincorporation and related
proposals will be the inclusion in the Company's charter of a new provision
further limiting director liability, the elimination of the shareholders'

                                       4
<PAGE>
 
ability to call a special meeting of shareholders (Proposal 1(a)), the addition
of new provisions requiring a supermajority vote of shareholders to amend or
repeal certain provisions of the bylaws and certificate of incorporation and
requiring a supermajority vote of directors to increase or reduce the number of
directors (Proposal 1(b)), and the institution of a seven-member Board of
Directors divided into three classes.  See "Changes in the Company's Charter to
be Effected by Reincorporation" and  "Certain Differences in State Corporation
Laws."

  Although not presently proposed or included in the new certificate of
incorporation or bylaws, Delaware law would allow the future inclusion of
certain other provisions not permitted under California law.  Such provisions,
subject to shareholder approval if later proposed by the Board of Directors,
would provide for greater continuity, stability and independence of the Board of
Directors.  The Company could also adopt share purchase rights plans, sometimes
referred to as "poison pills," which typically take the form of an issuance of a
dividend to shareholders of rights to acquire shares of the Company or an
acquiring corporation at less than half their fair market value.  The Company's
adoption of such a share purchase rights plan would not require shareholder
approval.  In addition, certain other provisions designed to discourage non-
negotiated takeover attempts, particularly those involving unequal treatment of
the Company's shareholders, could later be adopted.  The inclusion of such anti-
takeover provisions in the Summa Delaware certificate of incorporation, many of
which may be prohibited under California law, is permitted under Delaware law.

  The proposed reorganization and related proposals do not result from any
pending legal action against the officers, directors or employees of the
Company.  Similarly, the Board of Directors has no present knowledge of any
proposed tender offer or other attempt to change the control of the Company, and
no tender offer or other type of change of control is presently pending or has
occurred in the past.  Nonetheless, if such action were attempted in the future,
the laws of Delaware would be better suited to the defense of such action than
the laws of California.

Changes in Summa's Charter to be Effected by Reincorporation

  The following discussion summarizes the material differences between the
proposed certificate of incorporation and bylaws of Summa Delaware and the
restated Articles of Incorporation and Bylaws of Summa California.  A copy of
the form of certificate of incorporation of Summa Delaware is attached hereto as
Appendix II and a copy of the form of bylaws of Summa Delaware is attached
- -----------                                                               
hereto as Appendix III, and all statements herein concerning such documents are
          ------------                                                         
qualified by reference to the exact provisions thereof.  Approval of the
reorganization by the shareholders will result in the adoption of all such
charter provisions set forth in the Summa Delaware certificate of incorporation
and bylaws, except for those provisions set forth in Proposals 1(a) and 1(b)
below which require separate approval by the shareholders for adoption.

  Limitation of Liability and Indemnification.  Although both California and
  -------------------------------------------                              
Delaware law allow for some protection of directors with respect to personal
liability, there are certain differences between these laws regarding limitation
of liability and indemnification, which will be considered below.

  The California General Corporation Law permits California corporations to
include in their articles of incorporation a provision eliminating the liability
of a director to the corporation or shareholders for monetary damages except
under certain circumstances.  Under the California law, personal liability of a
director for monetary damages cannot be limited or eliminated where liability
arises from: (a) intentional misconduct or a knowing and culpable violation of
law; (b) acts or omissions that a director believes to be contrary to the best
interests of the corporation or its shareholders, or that involve the absence of
good faith on the part of the director; (c) receipt of an improper personal
benefit; (d) acts or omissions that show a reckless disregard for the director's
duty to the corporation or its shareholders, where the director in the ordinary
course of performing a director's duties should be aware of a risk of serious
injury to the corporation or its shareholders; (e) acts or omissions that
constitute an unexcused pattern of inattention that amounts to an abdication of
the director's duty to the corporation and its shareholders; (f) interested
transactions between the corporation and a director in which a director has a
material financial interest; and (g) improper distributions, loans or
guarantees.

  The Delaware General Corporation Law (the "DGCL") permits a corporation to
include a provision in its certificate of incorporation which limits or
eliminates the personal liability of a director for monetary damages

                                       5
<PAGE>
 
arising from breaches of his fiduciary duties to the corporation or its
shareholders, subject to certain exceptions. Such a provision is included in the
Summa Delaware certificate of incorporation. A director would still be liable in
such cases for the following: (i) breach of the director's duty of loyalty to
the Company or its shareholders; (ii) acts or omissions not in good faith or
involving intentional misconduct or a knowing violation of the law; (iii)
willful or negligent conduct in paying dividends or repurchasing stock out of
other than lawfully available funds (a violation of Section 174 of the DGCL); or
(iv) any transaction from which the director derives an improper personal
benefit. In effect, after the reincorporation, a director of the Company could
not be held liable for damages to the Company or its shareholders for gross
negligence or lack of due care in carrying out his fiduciary duties as a
director. He could still, however, be liable in such cases if the director acted
in bad faith or in breach of the director's duty of loyalty to the Company.

  The liability limitation provision in the Summa Delaware certificate of
incorporation will not extend to acts or omissions of a director which occurred
before the date on which the certificate of incorporation became effective.  The
provision also cannot limit a director's liability for violation of, or
otherwise relieve Summa Delaware or its directors from the necessity of
complying with, federal and state securities laws, nor affect the availability
of non-monetary remedies such as injunctive relief or rescission.

  California law permits indemnification of expenses incurred in derivative or
third-party actions, except that with respect to derivative actions (a) no
indemnification may be made without court approval when a person is adjudged
liable to the corporation in the performance of that person's duty to the
corporation and its shareholders, unless the court determines such person is
entitled to indemnity for expenses, and then such indemnification may be made
only to the extent that the court shall determine, and (b) no indemnification
may be made without court approval in respect of amounts paid or expenses
incurred in settling or otherwise disposing of a threatened or pending action or
amounts incurred in defending a pending action which is settled or otherwise
disposed of without court approval.  Indemnification is permitted by California
law only for acts taken in good faith and believed to be in the best interests
of the corporation and its shareholders, as determined by a majority vote of a
disinterest quorum of the directors, independent legal counsel (if a quorum of
independent directors is not obtainable), a majority vote handling the action of
a quorum of the shareholders (excluding shares owned by the indemnified party),
or the court in which the action is or was pending.

  Delaware law 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 the directors who are not parties to such
action, 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 shareholders, that the person seeking indemnification acted in good faith
and in a manner reasonably believed to be in or (in contrast to California law)
not opposed to the best interests of the corporation.  Without court approval,
however, no indemnification may be made in respect of any derivative action in
which such person is adjudged liable for negligence or misconduct in the
performance of his or her duty to the corporation.

  California law requires indemnification if the individual has successfully
defended the action on the merits.  Delaware law, in contrast, requires
indemnification in the event of a successful defense, whether on the merits or
otherwise.

  The bylaws of Summa Delaware provide for indemnification to the fullest
permitted by Section 145 of the DGCL and provide that expenses incurred by an
individual in his capacity as a director of the Summa Delaware or in certain
other capacities in defending a civil or criminal action shall be paid by Summa
Delaware in advance of the final disposition of the matter upon receipt of an
undertaking from the director to repay the sum advanced if it shall ultimately
be determined that he is not entitled to be indemnified by Summa Delaware
pursuant to the terms of the DGCL.  The form of this new bylaw provision is
included in Appendix III.
            ------------ 

  The certificate of incorporation of Summa Delaware also provides that if the
DGCL is amended in the future to reduce further the liability of a director for
breach of his fiduciary duty to Summa Delaware or its shareholders, such change
shall also apply to the directors of Summa Delaware.  While the Company is not
aware of any proposals in the Delaware legislature to limit further the
liability of directors, management of the Company and the Board of Directors
believe it is advisable in light of current conditions in the insurance markets
to make provision

                                       6
<PAGE>
 
for such changes now rather than to await a further stockholder vote on the
changes at a later date. In addition, the certificate of incorporation of Summa
Delaware provides that any future repeal or modification of the terms of the
certificate of incorporation shall not adversely affect any right or protection
of a director existing at the time of the repeal or modification.

  Elimination of Shareholder Ability to Call Special Meetings (Proposal 1(a)).
  --------------------------------------------------------------------------- 
California law permits holders of 10% of the outstanding voting securities of a
company to call a special meeting of shareholders.  Delaware law does not
require that shareholders be allowed to call a special meeting of shareholders.
If this Proposal 1(a) is approved by the Company's shareholders, the certificate
of incorporation of Summa Delaware will provide that special meetings of
shareholders may be called only by the Board of Directors, the Chairman of the
Board or the President.  Shareholders will not be permitted to call a special
meeting of shareholders.  The business permitted to be conducted at any special
meeting of shareholders would be limited to the business brought before the
meeting by the Board of Directors or by the person that called the special
meeting.  Elimination of the right of shareholders to call a special meeting
would eliminate a shareholder's ability to force shareholder consideration of a
proposal over the opposition of the Board of Directors by calling a special
meeting of shareholders prior to such time as the Board believed such
consideration to be appropriate.  For example, proposed amendments to the Bylaws
or removal of directors for cause could, if the Board of Directors so desired,
be delayed until the next annual meeting of shareholders.

  Shareholders should recognize that elimination of the procedure for
shareholders to call special meetings may render more difficult, discourage or
delay a merger, proxy contest or the assumption of control of the Company by a
large shareholder or group of shareholders.  To the extent that this provision
enables the Board of Directors to resist a takeover or change in control, it may
be more difficult to remove the existing Board of Directors and management.
This increased ability to resist a takeover or change in control of the Company
could be beneficial to shareholders if used by the Board of Directors and
management to discourage or delay insufficient offers and/or to negotiate
superior offers than may otherwise be obtainable.

  This provision does not result form any present knowledge on the part of the
Board of Directors of any proposed attempt to change the control of the Company,
and no change of control is presently pending or has occurred in the past.

  Change in the Number of Classes of Directors.  The proposed certificate of
  --------------------------------------------                              
incorporation and bylaws of Summa Delaware provide for a classified Board of
Directors in three classes and permit such Board to create new directorships and
to elect new directors to serve for the full term of the class of directors in
which the new directorship was created.  The terms of the directors are
staggered to provide for the election of approximately one-third of the Board
members each year, with each director serving a three-year term.  The Board (or
its remaining members, even though less than a quorum) is also empowered to
create and fill vacancies on the Board occurring for any reason for the
remainder of the term of the class of directors in which the vacancy occurred.
Assuming approval of Proposal 3 below, the Board of Directors of the Company
will be divided in two classes of directors serving staggered two year terms
until consummation of the reincorporation.

  Two-Thirds Supermajority to Amend Certain Provisions of Bylaws (Proposal
  ------------------------------------------------------------------------
1(b)). If this Proposal 1(b) is approved by the Company's shareholders, the
- -----
proposed certificate of incorporation of Summa Delaware will provide in Article
11 that (i) any amendment to the bylaws that increases or reduces the authorized
number of directors shall require the affirmative vote of at least 66-2/3% of
the directors and (ii) any amendment to the bylaws by the shareholders that
increases or reduces the authorized number of directors or the percentage vote
necessary to amend such provision of the bylaws will require the affirmative
vote of holders of 66-2/3's of the outstanding shares of stock of Summa
Delaware.  In contrast, the restated Articles of Incorporation of Summa
California currently provide that (i) the authorized number of directors is
fixed at nine (see, however, Proposal 3 below), and amendment of such Articles
of Incorporation under California law requires approval of a majority of the
outstanding shares entitled to vote, and (ii) any amendment or repeal of the
Bylaws may be made by a vote of holders of a majority of the outstanding shares
entitled to vote thereon.

                                       7
<PAGE>
 
  This provision is principally intended to prevent a shareholder or group of
shareholders having a majority of the Common Stock from making changes in the
bylaws to increase the number of directors.  However, the bylaws of the Company
will continue to be subject to change by a majority vote of the Board of
Directors, except for increases or decreases in the size of the Board which will
require a 66-2/3's vote of the Board of Directors.

  If approved by the Company's shareholders, this provision may have the effect
of discouraging efforts to acquire control of the Board of Directors.
Shareholders should recognize that this proposed amendment could render more
difficult or discourage a merger, tender offer, proxy contest or the assumption
of control of the Company by a large shareholder or group of shareholders.  To
the extent that this provision enables the Board of Directors to resist a
takeover or change in control of the Company, it could make it more difficult to
remove the existing Board of Directors and management.  This increased ability
to resist a takeover or change in control of the Company could be beneficial to
shareholders if used by the Board of Directors and management to discourage or
delay insufficient offers and/or to negotiate superior offers than may otherwise
be obtainable.

  This provision does not result from any present knowledge on the part of the
Board of Directors of any proposed tender offer or other attempt to change the
control of the Company and no tender offer or other type of change of control is
presently pending or has occurred in the past.

  Two-Thirds Supermajority to Amend Certain Articles of the Certificate of
  ------------------------------------------------------------------------
Incorporation (Proposal 1(b)). If this Proposal 1(b) is approved by the
- -----------------------------                                          
Company's shareholders, the proposed certificate of incorporation of Summa
Delaware will also provide in Article 11 that Articles 6, 7, 10,11 and 12 of
Summa Delaware's certificate of incorporation may be amended or repealed only by
a vote of holders of at least 66-2/3% of the outstanding voting shares of the
Company.  Articles 6, 7, 10, 11 and 12 are the provisions of Summa Delaware's
certificate of incorporation regarding the amendment of the Company's Bylaws to
increase or reduce the number of directors, the removal of directors, the
elimination of shareholder action by written consent, the amendment of Summa
Delaware's certificate of incorporation and the limitation of liability of
directors, respectively.  These provisions are discussed above.  Summa
California's restated Articles of Incorporation generally may be amended by a
vote of shareholders holding a majority of the shares.

  Article 11 of the certificate of incorporation of Summa Delaware is intended
to prevent the holder or holders of a majority of the voting shares of the
Company from circumventing the proposed provisions of the certificate of
incorporation described above by amending the certificate of incorporation to
delete or modify them.  Delaware law provides generally that the certificate of
incorporation may be amended by a vote of stockholders holding a majority of the
shares.  However, where the certificate of incorporation requires a
supermajority vote with respect to a particular matter, under Delaware law the
same supermajority vote is required to amend such supermajority requirement of
the certificate of incorporation.  Therefore, to amend or repeal the provision
in the certificate of incorporation, which requires the affirmative approval of
the holders of 66-2/3% of the outstanding Common Stock of the Company, the same
66-2/3% vote would be necessary.  Without the inclusion of this provision in the
Summa Delaware certificate of incorporation, the articles requiring a
supermajority vote could be repealed or amended by a vote of shareholders
holding a majority of shares.

  If approved by the Company's shareholders, Article 11 of the certificate of
incorporation of Summa Delaware may have the effect of discouraging efforts to
acquire control of the Board of Directors.  Shareholders should recognize that
these supermajority provisions could render more difficult or discourage a
merger, tender offer, proxy contest or the assumption of control of the Company
by a large shareholder or group of shareholders.  To the extent that this
provision enables the Board of Directors to resist a takeover or change in
control of the Company, it could make it more difficult to remove the existing
Board of Directors and management.  This increased ability to resist a takeover
or change in control of the Company could be beneficial to shareholders if used
by the Board of Directors and management to discourage or delay insufficient
offers and/or to negotiate superior offers than may otherwise be obtainable.

  This provision does not result from any present knowledge on the part of the
Board of Directors of any proposed attempt to change the control of the Company,
and no change of control is presently pending or has occurred in the past.

  Authorized Stock.  The restated Articles of Incorporation of Summa California
  ----------------                                                             
authorize 10,000,000 shares of Common Stock, $.001 par value, and 5,000,000
shares of Preferred Stock, $.001 par value.  The certificate of incorporation of
Summa Delaware will provide for the same number of shares of Common and
Preferred Stock, each with the same $.001 par value.  The restated Articles of
Incorporation of Summa California and the certificate of incorporation of Summa
Delaware each authorize the Board of Directors to fix the rights, preferences,
privileges and restrictions of one or more series of authorized shares of
Preferred Stock, including dividend rights, conversion rights, voting rights,
terms of redemption and liquidation preferences without further vote or action
by the shareholders.  Although the Board has no present intention of doing so,
issuance of the authorized Preferred Stock with terms giving it substantial
voting power, conversion or other rights could have the effect of (i) delaying,
deferring or preventing a change in control of the Company or (ii) otherwise
modifying the rights of holders of the Company's Common Stock under either
California or Delaware law.

Certain Differences in State Corporation Laws

  In addition to the matters discussed above, Delaware law differs in many
respects from California law.  Certain differences which could materially affect
the rights of shareholders are discussed below.

  Classified Board of Directors.  A classified board means that a certain
  -----------------------------                                          
number, but not all, of the directors are elected on a rotating basis each year.
Under California law, directors generally are elected annually, but classified
boards are permitted with certain minimum size restrictions.  Delaware law also
permits, but does not require, classified boards with staggered terms under
which one half or one third of the board members are elected annually, without
the minimum size restrictions contained in California law.  This method of
electing directors makes a change in the composition of a board of directors,
and a potential change in control of a corporation, a lengthier and more
difficult process.

  The restated Articles of Incorporation of Summa California and the certificate
of incorporation of Summa Delaware both provide for a classified Board of
Directors.  Although Summa California already has a classified Board of
Directors, in the event that the number of members on the Board of Directors is
reduced to seven (see Proposals 3 and 4 below), California law would require the
Board of Directors be divided into not more than two classes, with three members
in one class and four in the other and with members in each class serving two-
year terms, while Delaware law would permit the division of a seven-member Board
of Directors into three classes, with two, two and three members in such classes
and with members in each class serving three-year terms.  In approving Proposal
1, the shareholders would also be approving the division of the Board of
Directors into three classes.

  Removal of Directors.  Under California law, any director or the entire board
  --------------------                                                         
of directors may be removed, with or without cause, with the approval of a
majority of the outstanding shares entitled to vote; however, no individual
director may be removed (unless the entire board is removed) if the number of
votes cast against such removal would be sufficient to elect the director under
cumulative voting.  Under Delaware law, a director of a corporation with a
classified board of directors may be removed only for cause, unless the
certificate of incorporation otherwise provides.  The term "cause" with respect
to the removal of directors is not defined in the DGCL and its meaning has not
been precisely delineated by the Delaware courts.  The certificate of
incorporation and bylaws of Summa Delaware provide for a classified Board of
Directors.

  Certain Business Combinations.  In the past several years, a number of states
  -----------------------------                                                
(but not including California) have adopted special laws designed to make
certain kinds of "unfriendly" corporate takeovers, or other transactions
involving a corporation and one or more of its significant shareholders, more
difficult.  Under Section 203 of the DGCL ("Section 203"), certain "business
combinations" with "interested stockholders" of Delaware corporations are
subject to a three-year moratorium unless specified conditions are met.

  Section 203 prohibits certain mergers, consolidations, sales of assets and
other transactions ("business combinations") with an "interested stockholder"
(generally a 15% or more stockholder) for three years following the date the
stockholder became an interested stockholder.  The prohibition on business
combinations is subject to certain exceptions, the most significant of which are
that the prohibition does not apply if: (i) the business combination or
transaction in which the interested stockholder becomes an interested
stockholder is approved by

                                       9
<PAGE>
 
the board of directors prior to the stockholder becoming an interested
stockholder; (ii) the business combination is with an interested stockholder who
became an interested stockholder in a transaction whereby he acquired at least
85% of the corporation's voting stock; (iii) the business combination is
approved by the board of directors and authorized by the affirmative vote of at
least 66-2/3% of the outstanding voting stock which is not owned by the
interested stockholder; or (iv) an exemption is available.

  Section 203 is currently under challenge in lawsuits arising out of ongoing
takeover disputes, and it is not yet clear whether or to what extent its
constitutionality will be upheld by the courts.  The United States District
Court for the District of Delaware has consistently upheld the constitutionality
of Section 203 but the Delaware Supreme Court has not yet considered the issue.
So long as the constitutionality of Section 203 is upheld, the Company believes
that it will have the effect of encouraging any potential acquiror to negotiate
with the Company's Board of Directors.  Section 203 should also discourage
certain potential acquirors unwilling to comply with its provisions.

  Section 203 only applies to Delaware corporations which have a class of voting
stock that is listed on a national securities exchange, authorized for quotation
on an inter-dealer quotation system of a registered national securities
association (as is Summa California and as Summa Delaware will be), or are held
of record by more than 2,000 stockholders.  However, a Delaware corporation may,
through its certificate of incorporation or bylaws, elect not to be governed by
the statute.  The Summa Delaware certificate of incorporation and bylaws do not
contain such an election; consequently, the statute will apply to business
combinations involving Summa Delaware.

  Additional Takeover Protection.  Delaware law also allows the inclusion in a
  ------------------------------                                              
certificate of incorporation of certain provisions which may protect non-
controlling stockholders against unfavorable mergers or other business
combinations.  Some companies have adopted provisions requiring that unless
certain minimum price criteria and procedural requirements are satisfied,
business combinations must be approved by a supermajority of the holders of the
corporation's outstanding voting stock.  Such provisions are not being proposed
by the Company at this time and, if proposed in the future, would be subject to
approval by the shareholders of the Company.  Under California law, similar
provisions could be inserted in the Company's restated Articles of
Incorporation, but the vote required to approve any merger or business
combination could not exceed 66-23%.

  In addition, there is a substantial body of case law in Delaware addressing a
corporation's right to adopt share purchase rights plans, sometimes referred to
as "poison pills."  Such plans typically take the form of an issuance of a
dividend to stockholders of rights to acquire share of the Company or, under
certain circumstances, an acquiring corporation at less than half their fair
market value.  Adoption of a share purchase rights plan by Summa Delaware, which
would not require stockholder approval, could have the effect of delaying,
deferring or preventing a change in control of the Company.  There is no similar
body of law in California, and the validity of such plans is, therefore,
questionable.  If the reincorporation is approved, the Board of Directors may
consider the adoption of such a plan at some time in the future.

  Shareholder Voting and Appraisal Rights.  With certain exceptions, California
  ---------------------------------------                                      
law requires that a merger, sale of assets or similar transaction be approved by
a majority vote of each class of shares outstanding.  Delaware law does not
require such class voting, except in the case of transactions involving an
amendment to the certificate of incorporation that adversely affects a specific
class in a manner different than other classes.  Should the Company authorize
and issue shares of a new class of capital stock, the holders thereof would vote
with the holders of the Common Stock on proposals not adversely affecting the
Common Stock.  In such event the holders of Common Stock, if in the minority,
would be unable to control the outcome of the vote, and, if in the majority,
would be able to control the outcome of such a vote.  California law also
provides that, except in certain circumstances, when a tender offer or a
proposal for the reorganization or for a sale of assets is made by an interested
party (generally a controlling or managing party of the target corporation), an
affirmative opinion in writing as to the fairness of the consideration to be
paid to the shareholders must be delivered to the shareholders.  This fairness
opinion requirement does not apply to a corporation which does not have shares
held of record by at least 100 persons, or to a transaction which has been
qualified under California state securities laws.  Furthermore, if a tender of
shares or vote is sought pursuant to an interested party's proposal and a later
proposal is made by another party at least ten days prior to the date of
acceptance of the interested party's proposal, the shareholders must be informed
of the later offer and be afforded a reasonable opportunity to withdraw any
vote, consent or proxy, or to withdraw any tendered shares.  Delaware law has no
comparable provision and the stockholders of Summa Delaware might,

                                       10
<PAGE>
 
therefore, be deprived of an opportunity to consider such other proposals.

  Delaware law does not require dissenters' rights of appraisal with respect to
(a) a sale of assets in a reorganization, (b) a merger by a corporation, the
shares of which are either listed on a national securities exchange or widely
held (by more than 2,000 stockholders) if such stockholders receive shares of
the surviving corporation or of a listed or widely held corporation, or (c)
stockholders of a corporation surviving a merger if no vote of such stockholders
is required to approve the merger.  Under Delaware law no vote of the
stockholders of a corporation surviving a merger is required if the number of
shares to be issued in the merger does not exceed 20% of the shares of the
surviving corporation outstanding immediately prior to such issuance and if
certain other conditions are met.  California law does, in general, afford
dissenters' rights in a sale of assets reorganization, and its exclusions from
dissenters' rights in mergers are somewhat different from those in Delaware.
Dissenters' rights are not available under California or Delaware law to
shareholders of the Company with respect to the proposed reincorporation.

  Inspection of Shareholders List.  Both California and Delaware allow any
  -------------------------------                                         
shareholder to inspect the shareholders list for a purpose reasonably related to
such person's interest as a shareholder.  California law provides, in addition,
for an absolute right to inspect a copy of a corporation's shareholders list by
persons holding five percent or more of the corporation's voting shares, or any
shareholders holding one percent or more of the corporation's voting shares who
have filed a Schedule 14B with the Securities and Exchange Commission relating
to the election of directors.  Delaware law does not provide for any such
absolute right of inspection.  Lack of access to shareholder records could
result in impairment of a shareholder's ability to coordinate opposition to
management proposals, including proposals with respect to a change in control of
the Company.

  Dividends and Repurchases of Shares.  Delaware law permits a corporation,
  -----------------------------------                                      
unless otherwise restricted by its certificate of incorporation, to declare and
pay dividends out of surplus or, if there is no surplus, out of net profits for
the fiscal year in which the dividend is declared and/or for the preceding
fiscal year, as long as the amount of capital for the corporation is not less
than the aggregate amount of the capital represented by the issued and
outstanding stock of all classes having a preference upon the distribution of
assets.  In addition, Delaware law generally provides that a corporation may
redeem or repurchase its shares provided such redemption or repurchase would not
impair the capital of the corporation.  The ability of a Delaware corporation to
pay dividends on, or to make a repurchase or redemption of, its shares is
dependent on the financial status of the corporation standing alone, not
considered with subsidiary or parent corporations.  In determining the amount of
surplus of a Delaware corporation, the assets of the corporation, including
stock of subsidiaries owned by the corporation, must be valued at their fair
market values as determined by the corporation's board of directors, regardless
of their historical book value.

  Under California law, any distribution to shareholders (including dividends
and repurchases of shares) is limited either to retained earnings or to an
amount that would leave the corporation with assets (exclusive of goodwill,
capitalized research and development expenses and deferred charges) in an amount
equal to at least 125% of its liabilities (exclusive of deferred taxes, deferred
income and other deferred credits) and with current assets in an amount at least
equal to current liabilities (or 125% of its current liabilities if the average
pre-tax and pre-interest earnings for the preceding two fiscal years were less
than the average interest expenses for such years).  Such limitations are
applied to California corporations on a consolidated basis.  Under California
law, there are certain exceptions to the foregoing limitations for repurchases
of shares in connection with certain rescission actions or pursuant to certain
employee stock plans.

  Loans to Officers and Employees.  Under California law, any loan or guaranty
  -------------------------------                                             
to or for the benefit of a director or officer of the corporation or its parent
corporation requires approval of the shareholders unless such loan or guaranty
is provided under a plan approved by shareholders owning a majority of the
outstanding shares of the corporation.  In addition, under California law,
shareholders of any corporation with 100 or more shareholders of record may
approve a bylaw authorizing the board of directors alone to approve loans or
guaranties to or on behalf of officers (whether or not such officers are
directors) if the board of directors determines that any such loan or guaranty
may reasonably be expected to benefit the corporation.  The Bylaws of Summa
California do not specifically authorize such loans or guaranties.  Under
Delaware law, a corporation may make loans to, guarantee the obligations of or
otherwise assist its officers and other employees and those of its subsidiaries
(including

                                       11
<PAGE>
 
directors who are also officers or employees) when such action, in the judgment
of the board of directors, may reasonably be expected to benefit the
corporation.

  Dissolution.  Under California law, shareholders holding 50% or more of the
  -----------                                                                
total voting power may authorize a corporation's dissolution, with or without
the approval of the corporation's board of directors, and this right may not be
modified by the articles of incorporation.  Under Delaware law, unless the board
of directors approves the proposal to dissolve, the dissolution must be approved
by shareholders holding 100% of the total voting power of the corporation.  Only
if the dissolution is initiated by the board of directors may it be approved by
a simple majority of the voting power.  In the event of such board-initiated
dissolution, Delaware law allows a Delaware corporation to include in its
certificate of incorporation a supermajority voting requirement in connection
with dissolutions.  Summa Delaware's certificate of incorporation contains no
such supermajority voting requirement and, therefore, a majority of shares
voting at a meeting in which a quorum is present would be sufficient to approve
a dissolution of Summa Delaware which had previously been approved by its Board
of Directors.

Application of California Law After Reincorporation

  If the proposed reorganization is effected, it is possible that Summa Delaware
will be subject to certain provisions of California's corporation laws in the
present or future.  Since Delaware and California law conflict in certain areas,
it is uncertain which law would prevail.  Section 2115 of the California
Corporations Code provides that if the average of certain property, payroll and
sales factors results in a finding that more than 50% of Summa Delaware's
business is conducted in California for a particular fiscal year and more than
50% of Summa Delaware's outstanding voting securities are held of record by
persons having addresses in California, Summa Delaware will become subject to
certain provisions of California law regardless of its state of incorporation.
Summa Delaware would continue to be subject to such provisions until the end of
any fiscal year in which 50% or more of its business is conducted outside of
California or 50% or more of its outstanding voting securities are held by
persons having addresses outside of California.  Foreign corporations which have
securities listed on the New York or American Stock Exchange, and foreign
corporations which have a class of securities trading as a Nasdaq National
Market security with at least 800 equity holders as of the date of its most
recent annual meeting of shareholders, are exempt from Section 2115.  As of
December 5, 1997, Summa California had 500 holders of record and estimates
approximately 600 additional beneficial owners.  Therefor, Summa Delaware will
likely be exempt from application of Section 2115.

  If Summa Delaware is subject to the provisions of California law referred to
above, and such provisions are enforced by the courts in a particular case, may
of the Delaware laws described under "Changes in the Company's Charter to be
Effected by Reincorporation" and "Certain Differences in State Corporation Laws"
would not apply to Summa Delaware.  The California provisions relating to the
election and removal of directors, classified boards of directors, standard of
liability for directors, indemnification of directors, dividends and repurchases
of shares, shareholder meetings, approval of certain corporate transactions,
appraisal rights and inspection of records would apply.  Because the Company
believes that Summa Delaware will be exempt from application of Section 2115,
reincorporation is appropriate at this time.

Federal Income Tax Consequences

  The reorganization provided for in the Agreement and Plan of Merger is
intended to be tax free under the Internal Revenue Code of 1986, as amended.
Assuming the reincorporation qualifies as a reorganization, no gain or loss will
be recognized to the holders of Summa California shares as a result of the
consummation of the reorganization, and no gain or loss will be recognized by
Summa California or Summa Delaware.  Each former holder of Summa California
shares will have the same basis in the Summa Delaware stock received by such
holder pursuant to the reorganization as the holder had in the Summa California
shares held by such holder at the time of the consummation of the
reorganization, and his holding period with respect to Summa Delaware stock will
include the period during which the holder held the corresponding Summa
California shares, provided the latter were held by the holder as capital assets
at the time of the consummation of the reorganization.  The Company has not
obtained a ruling from the Internal Revenue Service or an opinion of legal or
tax counsel with respect to the consequences of the reincorporation.  The
foregoing is only a summary of certain federal income tax consequences.

Recommendation of Board; Vote Required for Approval

  The Board of Directors recommends that the Company reincorporate in the State
of Delaware because of that state's comprehensive, modern and flexible corporate
laws and because the reincorporation will assist the Company in retaining and
attracting the most qualified persons as officers and directors.  Accordingly,
the Board of Directors has unanimously approved Proposal 1 and the related
proposals and unanimously recommends shareholders vote "FOR" approval of the
reincorporation and each of the related proposals.  Approval of Proposal 1 and
each of the related proposals will require the affirmative vote of a majority of
the outstanding shares of the Company's Common Stock entitled to vote.


                                PROPOSAL NO. 2
                      AMENDMENT OF 1995 STOCK OPTION PLAN

Background of and Reasons for the Amendment

  Under the Company's existing stock option plans, including the 1995 Stock
Option Plan ("1995 Plan") approved by the shareholders at the 1995 Annual
Meeting, only 23,377 shares remain available for the grant of options to
purchase shares of the Company's Common Stock.  See "Executive Compensation and
Other Information - Stock Option Plans" below.  The Company's Board of Directors
believes it is in the best interests of the Company and its shareholders to
amend the 1995 Plan to increase the number of shares available for the grant of
stock options by 100,000 to provide incentives to officers and other key
employees of the Company to remain with and increase their efforts on behalf of
the Company, and to enable the Company's management to grant stock options to
non-employee directors and others expected to provide significant services to
the Company.  Additionally, if key executives are to be recruited in the future,
the availability of stock options is necessary for the Company to offer
competitive compensation packages.  Accordingly, the Board of Directors has
unanimously approved increasing the shares available for the grant of stock
options by 100,000 and, therefore, at the Annual Meeting the second matter to be
presented to the shareholders of the Company for their consideration and
approval will be a proposal to amend the 1995 Plan to increase the number of
shares available for the grant of stock options by 100,000, from 250,000 to
350,000.

Description of the 1995 Stock Option Plan

  Subject to typical antidilution provisions for stock splits, stock dividends
and the like, the 1995 Plan authorizes the grant of options to purchase an
aggregate of up to 250,000 shares of the Company's Common Stock.  As of December
5, 1997 (i) the aggregate market value of these 250,000 share of Common Stock
was $2,375,000, based upon a closing sale price of the Common Stock on that date
as reported on The Nasdaq National Market, and (ii) options to purchase up to
243,223 shares of Common Stock have been granted to employees and non-employee
directors under the 1995 Plan, with exercise prices equal to the closing sale
prices for the Company's Common Stock on the dates of grant.  If an option
granted under the 1995 Plan expires or terminates, the shares subject to any
unexercised portion of that option will again become available for the issuance
of further options under the 1995 Plan.  Stock options may be granted under the
1995 Plan which are intended to qualify as incentive stock options ("ISOs")
under Section 422A of the Internal Revenue Code of 1986, as amended (the
"Code"), or, alternatively, as stock options which will not so qualify
("Nonstatutory Stock Options").  The 1995 Plan will terminate on October 18,
2005, and no options may be granted under the 1995 Plan thereafter.

  The 1995 Plan permits administration either by the Board of Directors or by a
committee thereof consisting of at least three members of the Board who have
been appointed by the Board (the "Committee"), and is currently administered by
the Board of Directors.  The Board of Directors has the authority to select the
persons to receive options granted under the 1995 Plan, the extent of their
participation, and the terms and conditions of each stock option, subject to
certain limitations set forth in the 1995 Plan.  Full time officers and
employees of the Company or its subsidiaries are eligible to be granted ISOs
under the 1995 Plan.  Directors are only eligible to receive ISOs if they are
also full time employees of the Company.  In addition, full and part time
employees, officers, non-

                                       13
<PAGE>
 
employee directors, consultants, major vendors and others expected to provide
significant services to the Company may be granted Nonstatutory Stock Options
under the 1995 Plan. The Company presently employs approximately 600 persons on
a full time basis, all of whom (except for members of the Committee, if there be
one) are eligible for selection as participants under the 1995 Plan.

  Options granted under the 1995 Plan become exercisable in accordance with the
terms of the grant made by the Board of Directors, as set forth in a written
stock option agreement to be entered into by all participates receiving options
granted under the 1995 Plan.  The Board of Directors has discretionary authority
to select plan participants for among eligible persons and to determine at the
time an option is granted whether it is intended to be an ISO or a Nonstatutory
Stock Option, and when and in what increments shares covered by the option may
be purchased.  Options may be granted on terms providing that they will be
exercisable either in whole or in part at any time or times during their
respective terms, or only in specified percentages at stated time periods or
intervals during the term of the option.  While the 1995 Plan does not limit the
number of shares as to which options may be granted to any one participant
(including officers and directors of the Company), it does provide that no
employee may be granted ISOs which first become exercisable in any calendar year
to purchase shares of Common Stock having a fair market value (determined at the
time of the grant of the option) in excess of $100,000, reduced by the fair
market value (similarly determined) of any shares subject to ISOs granted under
any other plan of the Company which also become exercisable in such calendar
year.

  For employees holding more than ten percent of the total combined voting power
of all classes of outstanding stock, the purchase price of each option granted
under the 1995 Plan cannot be less than 110% of the fair market value per share
of the Company's Common Stock subject thereto on the date of the grant.  For all
other participants, the option exercise price may not be less than the fair
market value per share of the Company's Common Stock subject thereto on the date
of the grant in the case of an ISO, nor less than 85% of the fair market value
per share of the Company's Common Stock on the date of the grant in the case of
Nonstatutory Stock Options.  Upon exercise of an option, the exercise price
shall be payable in full to the Company.  The fair market value per share will
generally be the closing bid quotation for a share of the Company's Common Stock
on the date an option is or was granted under the 1995 Plan.  If there is no
market price available on such date, the fair market value per share will be
determined on the basis of factors deemed relevant by the Board, including,
without limitation, the book value of the shares on such date and the earnings
of the Company.

  The Board of Directors may in its discretion also include in a stock option
agreement a provision making the exercise price of any option granted under the
1995 Plan payable in full (i) in cash, (ii) by surrender of shares of the
Company's Common Stock having a market value equal to the aggregate exercise
price of all shares to be purchased, (iii) by cancellation of indebtedness owed
by the Company to the optionee, (iv) by a combination of (i)-(iii), or (v) by a
full recourse promissory note executed by the optionee.  If payment is made by
means of a promissory note, the shares purchased generally would be held in
pledge to secure payment of the note. Unless and until the purchaser defaulted
under the promissory note or governing instruments, the shares so pledged would
remain registered in the name of the purchaser, and the purchaser would be
entitled to vote the shares and to receive all dividends and any other amounts
accruing as a result of his or her ownership of such shares.

  If an optionee's employment is terminated other than for cause, the employee
will have the right to exercise his or her option to the extent then
exercisable, at any time within a three month period thereafter.  If an optionee
dies while still employed, or within the period of time after his or her
voluntary retirement specified in the applicable stock option agreement, the
option may be exercised at any time within twelve months thereafter by his or
her estate or by the person or persons to whom rights under the option passed by
will or the laws of descent or distribution, but only to the extent such option
was exercisable by him or her on that date.  The Board of Directors may
accelerate the time at which options may be exercised.  Options granted under
the 1995 Plan are not transferable except by will and the laws of descent and
distribution.  During the life of the person to whom an option is granted, that
person alone may exercise such option.

  Within the limits of the 1995 Plan, the Board of Directors may also modify,
extend or renew outstanding options or accept the cancellation of outstanding
options (to the extent not previously exercised) for the granting of new stock
options in substitution therefor.  However, no modification of an option which
alters or impairs any rights or obligations under any option previously granted
may be made without the consent of the optionee.

                                       14
<PAGE>
 
  The Board of Directors may, without affecting any outstanding options, from
time to time revise or amend the 1995 Plan, and may suspend or discontinue it at
any time.  However, no such revision or amendment may either increase the number
of shares subject to the 1995 Plan (with the exception of adjustments resulting
from changes in capitalization) or change the class of participants eligible to
receive options granted under the 1995 Plan without shareholder approval.

  In the event that the Company should elect to dissolve, merge or consolidate
with any other corporation, sell substantially all of its assets to another
person or entity, or enter into any other reorganization in a transaction in
which the Company is not the surviving corporation, the date of exercisability
of each option outstanding under the 1995 Plan will be accelerated to a date
prior to such transaction unless provision is made in connection with such
transaction for the assumption of the option or substitution of new options with
appropriate adjustments by the surviving corporation.  In connection with
Proposal 1 above, provision for the assumption of all outstanding options by the
surviving Summa Delaware corporation will be made.

  In general, neither the grant nor the exercise of ISOs under the 1995 Plan
will result in the recognition of taxable income to the optionee nor the
recognition of a federal income tax deduction to the Company.  In addition, the
subsequent sale of the option shares by the optionee will not result in a
federal income tax deduction to the Company, but gains recognized by the
optionee upon such sale will be deemed ordinary income or capital gains
depending on the length of time involved.  In general, the grant of a
Nonstatutory Stock Option will not result in either the recognition of taxable
income nor a federal income tax deduction to the optionee and the Company,
respectively.  Upon exercise, the optionee generally will recognize ordinary
income for federal income tax purposes equal to the excess of the fair market
value of the Company's Common Stock as of the date of exercise over the exercise
price paid for such option shares, and the Company will be entitled to a federal
income tax deduction equal to the amount of ordinary income recognized by the
optionee.  In general, further gain or loss realized by such optionee on the
subsequent disposition of such option shares will be long term or short term
capital gain or loss, depending on the length of time the option shares are held
after the option is exercised.

  The foregoing summary description of the 1995 Plan does not purport to be
complete, and reference is made to the entire 1995 Plan which sets forth in
detail all of the terms and conditions upon which stock options may be granted
thereunder.  A complete copy of the 1995 Plan will be provided without charge,
upon written or oral request, to any shareholder to whom this Proxy Statement is
being sent.  Requests should be made to the Corporate Secretary of the Company

Recommendation of the Board; Vote Required for Approval

  The Board of Directors believes that Proposal 2 is in the best interests of
the Company and its shareholders.  Therefor, the Board of Directors has
unanimously approved this Proposal 2 and has recommended that the shareholders
of the Company vote FOR approval of the proposed amendment to the 1995 Plan.
Approval of Proposal 2 will require the affirmative vote of a majority of the
shares of the Company's Common Stock represented in person or by proxy at the
Annual Meeting and entitled to vote.


                                PROPOSAL NO. 3
             AMENDMENT OF THE COMPANY'S ARTICLES OF INCORPORATION
                                        
Background of and Reasons for the Amendment

  The Company's Articles of Incorporation were originally adopted as the
articles of incorporation of Southern California Plastics Company, a predecessor
of the Company, in 1942 and have been amended a number of times over the
intervening years.  Following shareholder approval, the Articles of
Incorporation were restated in their entirety on December 20, 1993.  The
restatement included, among other things, classification of the Board of
Directors into two classes serving staggered two-year terms and the elimination
of cumulative voting for the

                                       15
<PAGE>
 
election of directors. More recently, the restated Articles of Incorporation
were amended to specify that the Board of Directors be comprised of nine members
divided into three classes of three members each serving staggered three-year
terms. During October 1997, Messrs. Palmaer and Morehouse, two of the Company's
nine directors, retired from the Board of Directors. The Board of Directors
believes that the Company will be managed efficiently and effectively with a
Board consisting of seven members. At the Annual Meeting, the third matter to be
presented to the shareholders of the Company for their consideration and
approval will be a proposal to amend the restated Articles of Incorporation to
specify that the Board of Directors be comprised of not less than six nor more
than nine members divided into two classes serving staggered terms of two years,
with one-half of the directors or as close an approximation as possible being
elected at each annual meeting of shareholders.

The Amendment Proposal

  The only modification to the restated Articles of Incorporation that would be
effected by approval of this Proposal 3 would be to provide that the Board of
Directors be comprised of not less than six nor more than nine members divided
into two classes serving staggered two-year terms.  As a result, approximately
one-half of the Company's directors would be elected each year at each annual
meeting of shareholders. The restated Articles of Incorporation currently
provide for a Board of Directors consisting of nine members divided into three
classes serving staggered three-year terms.

  A complete copy of the Company's restated Articles of Incorporation will be
provided without charge, upon written or oral request, to any shareholder to
whom this Proxy Statement is being sent.  Requests should be made to the
Corporate Secretary of the Company at 21250 Hawthorne Boulevard, Suite 500,
Torrance, California 90503; telephone (310) 792-7024; facsimile (310) 792-7079.

Recommendation of the Board; Vote Required for Approval

  The Board of Directors believes that Proposal 3 is in the best interests of
the Company and its shareholders and that the Company will be managed
efficiently and effectively with a board consisting of seven members.  With the
recent retirement of directors Palmaer and Morehouse, the Board of Directors has
not identified suitable replacements for such gentlemen, and does not believe
that replacement is necessary or desirable at this time.  In recent years, the
size of the Board of Directors has increased, due in part to acquisitions
consummated by the Company with the former chief executive of the acquired
company thereafter joining the Board of Directors.  The Board of Directors does
not believe that nine members are necessary to fully and accurately analyze
issues presented and to thoroughly debate the merits of such issues, and
believes that a Board of Directors consisting of seven members will be of
sufficient size and experience to manage the Company in an appropriate manner at
less expense than with nine members.  Therefor, the Board of Directors has
unanimously approved Proposal 3 and has recommended that the shareholders of the
Company vote FOR approval of amendment of the restated Articles of
Incorporation.  Approval of Proposal 3 will require the affirmative vote of a
majority of the outstanding shares of the Company's Common Stock entitled to
vote.


                                PROPOSAL NO. 4
                             ELECTION OF DIRECTORS

  Assuming approval by the shareholders of Proposal 3 above, seven directors,
comprising the entire Board of Directors of the Company, are to be elected at
the Annual Meeting, with three directors elected to Class I to serve a one-year
initial term and four directors elected to Class II to serve an initial two-year
term.  In the event the shareholders approve Proposal 1 above, then upon
consummation of the reincorporation, Class II will be subdivided into two
classes of two directors each, with the two directors comprising the new Class
III serving an initial term of three years from the date of the Annual Meeting.

  Should any of the nominees decline or be unable to serve as a director, the
persons authorized in the proxy to vote on your behalf will vote for such
substitute nominees as may be recommended by the Company's existing Board of
Directors, unless other directions are given in the proxy.  Each of the nominees
has consented to serve as a director if elected, and the Company knows of no
reason why any nominee listed below would not be available

                                       16
<PAGE>
 
for election or, if elected, would not be willing or able to serve. Unless
otherwise directed in the accompanying proxy, the persons named therein will
vote FOR the election of the seven director nominees set forth below.

  The following table sets forth certain information concerning each of the
seven nominees for election as directors of the Company:

Composition of Classified Board

  In the event that the shareholders approval Proposal 3 above, the Board of
Directors will initially consist of seven members and will be classified into
two classes of directors, with three members in Class I and four members in
Class II.  Members of Class I would hold office initially for a one-year term
expiring at the Annual Meeting of Shareholders for the 1998 fiscal year, and
members of Class II would hold office initially for a two-year term expiring at
the Annual Meeting of Shareholders for the 1999 fiscal year; provided that, if
Proposal 1 above is also approved, then Messrs. Horst and Zimmerman will form a
new Class III upon consummation of the reincorporation and will hold such office
for the remainder of a three-year term expiring at the Annual Meeting of
Shareholders for the 2000 fiscal year.  At each annual meeting following this
initial classification and election, the successors to the class of directors
whose terms expire at that meeting would be elected for a term of office to
expire on the second succeeding annual meeting of shareholders after their
election (or the third succeeding annual meeting if the reincorporation is
consummated) or until their successors have been duly elected and qualified.
The classes would be divided as follows:

     Class I, to hold office until the fiscal 1998 Annual Meeting of
     Shareholders:

              Mr. Coalson C. Morris
              Mr. James R. Swartwout

     Shareholders (to be formed only if the reincorporation in Proposal 1 is
     approved and consummated):

              Mr. Michael L. Horst
              Mr. William R. Zimmerman

Meetings of the Board; Committees and Director Compensation

he serves.  The Company has no standing committees, other than the Audit
Committee.  The principal duties of the Audit Committee are to advise the Board
on audit matters affecting the Company, including

                                       18

     Secretary and General Counsel, as Mr. Thoresen became employed by the
     Company after the end of the 1997 fiscal year.  Mr. Thoresen was employed
     by Calnetics Corporation until its acquisition by the Company in October
     1997.  Mr. Thoresen's current annual base salary is $120,000 and his last
     bonus received from Calnetics was $15,000.  In connection with the
     acquisition of Calnetics, 50,000 stock options then held by Mr. Thoresen
     were converted into 64,615 options to purchase shares of the Company's
     Common Stock.  In addition, Mr. Thoresen has use of a Company automobile.

(2)  Consists of a stock award to Mr. Swartwout of 5,000 shares in fiscal 1995,
     valued at the average of the high and low trading price of the Company's
     Common Stock on the date of award.

(3)  Includes payments for a long term disability insurance policy,
     contributions to the Company's 401(k) Plan, automobile allowance and/or
     payment of certain accrued vacation amounts.


Employment Agreements

  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 the
Company 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 the Company (defined as the acquisition
by a person or group of either 30% or more of the Company's voting power or the
right to elect a majority of the Company's directors, 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 the Company'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.

  Pursuant to a change in control agreement entered into in January 1997 between
Trygve M. Thoresen and Calnetics Corporation and assumed by the Company upon
consummation of the acquisition of Calnetics, in the event that there is a
change in control of Calnetics and, thereafter, Mr. Thoresen is terminated
without cause or resigns from the successor for "good reason," the Company will
be required to pay Mr. Thoresen a lump sum

                                       20

distribution equal to one year's salary and bonus. The acquisition of Calnetics
by the Company constituted a change in control as defined in the agreement.

additional profit-sharing contributions at the discretion of the Board of
Directors. The total Company contribution to all employees' 401(k) accounts in
fiscal 1997 was approximately $357,000. Each of the named executive officers

Report of the Board of Directors on Executive Compensation

  The Board of Directors generally administers the Company's executive
compensation programs as the Company does not have a separate compensation
committee.  Individual directors who are also executive officers do not
participate in decisions regarding their compensation.  It is the policy of the
Board of Directors to establish compensation levels for executive officers which
reflect the Company's overall performance, responsibilities and contributions to
the long-term growth and profitability of the Company.  The Board of Directors
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.  In determining the base
salary and bonus for James R. Swartwout, the Chief Executive Officer of the
Company, the Board of Directors, without Mr. Swartwout, considered the foregoing
factors.

  Base Salary and Discretionary Bonus.  The principal component of the
  -----------------------------------                                 
compensation of the executive officers is their base salaries.  The Board of
Directors also retains discretion to award bonuses based on corporate or
individual performance.  The Board of Directors 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 Chief Executive Officer and, to a lesser
extent, the other executive officers.  Throughout the year, the members of the
Board of Directors review the corporate and individual performance factors
described above.  The Board of Directors, 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 Chief Executive Officer
and the other executive officers.

  Stock Options. The Board of Directors also considers the grant of stock
  -------------                                                          
options to the Company's key employees, including the executive officers.  The
purpose of the stock option program is to provide incentives to the Company's
management and other employees 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 stock option
grants to executive officers are derived based upon review of competitive
compensation practices with respect to the same or similar executive positions,
overall corporate performance and individual performance.

Compensation Committee Interlocks and Insider Participation

  The Board of Directors of the Company has not established a formal
Compensation Committee.  Rather, the entire Board reviews the performance and
establishes the compensation of Mr. Walbrun, and the entire Board, with the
exception of Mr. Swartwout, performs the same function relating to Mr.
Swartwout.  With the exception of Mr. Swartwout, none of the members of the
Board of Directors is a current officer or employee of the Company.  Mr. Barnes
is the former Chief Executive Officer and director of the Company's LexaLite
subsidiary, and Mr. Morris is a former officer of the Company.  There are no
compensation committee interlocks between the Company's Board of Directors and
other entities involving the Company's executive officers and Board members who
serve as executive officers or board members of such other entities.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

  The Company paid commissions in the amount of $120,000 and consulting fees of
$28,000 to a company controlled by Josh T. Barnes, a director of the Company, in
accordance with a design and consulting agreement entered into in 1993 by
LexaLite, which was acquired by the Company in November 1996.  In addition, the
Company paid a one time payment of $365,000 in consideration of amending the
terms of the earlier agreement by which LexaLite will continue to receive
consulting services for $30,000 per year and pay commissions of 0.75% (a
reduction from the previously existing rate) of sales of certain products up to
the earlier to occur of the cumulative commission payment of $650,000 or the
expiration of twelve years.

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

  One of the Company's subsidiaries leases truck trailers from a company owned
by a non-officer employee of the subsidiary under which the Company paid $25,000
in fiscal 1997, and under which the Company is obligated to pay approximately
$2,000 per month through June 2001.  Additionally, the Company's subsidiary paid
that party $379,000 for trucking services under an agreement which is renewable
annually.  The amounts paid are considered to be at commercially competitive
rates.

  In June 1994, prior to its ownership by the Company, one of the Calnetics'
subsidiaries entered into a four-year parts purchase and supply agreement with a
third party injection molder whereby such molder agreed to supply the subsidiary
with various injection molded parts, and the subsidiary agreed to purchase its
reasonable needs of such parts.  The agreement to purchase its reasonable needs
decreases each year, such that by the fourth year the subsidiary need only
purchase 25% of its reasonable needs from the third party molder.  The president
of the subsidiary is a director of the third party molder, owns approximately
nine percent of the molder's stock and has guaranteed payment of certain
indebtedness of the molder to a financial institution.  For its fiscal year
ended June 30, 1997, the subsidiary purchased $1,581,387 in parts from the third
party molder.  The amounts paid for such purchases are considered to be at
commercially competitive rates.

                                       26
<PAGE>
 
  The Company borrowed $400,000 from the president of one of the Company's
subsidiaries in 1993 to replace existing bank debt.  As of August 31, 1997, the
remaining principal balance on such indebtedness was $200,000, with principal
payments of $100,000 due in fiscal 1999 and 2000.  Interest paid to the officer
in accordance with the terms of a promissory note documenting such indebtedness
totaled $26,000 in fiscal 1997.


               COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT

  Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), requires the Company's executive officers and directors, and
persons who beneficially own more than ten percent of a registered class of the
Company's equity securities, to file reports of beneficial ownership and changes
in beneficial ownership (Forms 3, 4 and 5) with the Securities and Exchange
Commission.  Officers, directors and such more than ten percent beneficial
owners are required to furnish the Secretary of the Company with copies of all
such forms which they file.

  To the Company's knowledge, bases solely upon the Company's review of such
reports or written representations from certain reporting persons that no
reports were required, the Company believes that during fiscal 1997, all of its
directors and executive officers complied with Section 16(a) requirements,
except one report filed late on Form 5 by Paul Walbrun relating to stock options
received and beneficial ownership thereof.

                            INDEPENDENT ACCOUNTANTS

  The accounting firm of Arthur Andersen LLP served as the Company's independent
certified public accountants for the fiscal year ended August 31, 1997, and the
Company may engage Arthur Andersen LLP to audit the Company's financial
statements for the fiscal year ended August 31, 1998.  One or more
representatives of Arthur Andersen LLP are expected to be present at the Annual
Meeting, and to be available to respond to questions directed to their
attention.  These representatives will have an opportunity to make a statement.

                                 ANNUAL REPORT

  The Company's Annual Report on Form 10-K for the fiscal year ended August 31,
1997 ("Annual Report"), which contains audited financial statements of the
Company, has been mailed concurrently with the mailing of the Notice of Annual
Meeting and Proxy Statement to all shareholders entitled to notice of and to
vote at the Annual Meeting.  The Annual Report is not incorporated by reference
into this Proxy Statement and is not considered proxy solicitation material.
Any shareholder who has not received a copy of the Annual Report may obtain one
at no charge by writing to the Secretary of the Company at the address given on
the first page of this Proxy Statement.  The Company will furnish to any
shareholder of the Company any specific exhibit(s) to the Annual Report upon
written request and upon payment of the Company's reasonable expenses in
furnishing such exhibit(s).

                           PROPOSALS OF SHAREHOLDERS

  Proposals of shareholders intended to be presented at the Company's Annual
Meeting of Shareholders for the 1998 fiscal year must be received in writing by
the Secretary of the Company at the address given on the first page of this
Proxy Statement within a reasonable time before solicitation will be made to be
included in the proxy statement and proxy relating to that meeting.  The Company
anticipates that such Annual Meeting will be held in November 1998, December
1998 or January 1999 and, therefor, it is the Company's position that any such
shareholder proposals should be received by the Company prior to July 1998.

  The Board of Directors knows of no other business that will be presented for
consideration at the Annual Meeting.  If other matters are properly brought
before the Annual Meeting, however, it is the intention of the persons named in
the accompanying proxy to vote the shares represented thereby on such matters in
accordance with their best judgment.

       ------------------------------                                           
Surviving Corporation shall assume and continue the stock option plans and all

share of Summa California Common Stock issuable pursuant to any such option, or

       A number of shares of the Surviving Corporation's Common Stock will be

share of Summa Delaware Common Stock, $.001 par value, issued and outstanding
immediately prior thereto shall, by virtue of the Merger and without any action
by Summa Delaware, the holder of such share or any other person, be canceled and
returned to the status of authorized but unissued shares.

  3.4  Exchange of Certificates.  At the Effective Time of the Merger, each
       ------------------------                                            
holder of an outstanding certificate representing shares of Summa California
Common Stock may, at such stockholder's option, surrender the same for
cancellation to U.S. Stock Transfer Corporation, as exchange agent (the
"Exchange Agent"), and each such holder shall be entitled to receive in exchange
therefor a certificate or certificates representing the number of shares of the
Surviving Corporation's Common Stock into which the surrendered shares were
converted as herein provided.  Until so surrendered, each outstanding
certificate theretofore representing shares of Summa California Common Stock
shall be deemed for all purposes to represent the number of whole shares of the
Surviving Corporation's Common Stock into which such shares of Summa California
Common Stock were converted in the Merger.

       The registered owner on the books and records of the Surviving
Corporation or the Exchange Agent of any such outstanding certificate shall,

otherwise accounted for to the Surviving Corporation or the Exchange Agent, have
and be entitled to exercise any voting and other rights with respect to and to
receive dividends and other distributions upon the shares of Common Stock of the
Surviving Corporation represented by such outstanding certificate as provided
above.

       Each certificate representing Common Stock of the Surviving Corporation
so issued in the Merger shall bear the same legends, if any, with respect to the
restrictions on transferability as the certificates of Summa California so
converted and given in exchange therefore, unless otherwise determined by the
Board of Directors of the Surviving Corporation in compliance with applicable
laws.

       If any certificate for shares of Summa Delaware stock is to be issued in
a name other than that in which the certificate surrendered in exchange therefor
is registered, it shall be a condition of issuance thereof that the certificate
so surrendered shall be properly endorsed and otherwise in proper form for
transfer, that such transfer otherwise be proper and that the person requesting
such transfer pay to the Exchange Agent any transfer or other taxes payable by
reason of issuance of such new certificate in a name other than that of the
registered holder of the certificate surrendered or establish to the
satisfaction of Summa Delaware that such tax has been paid or is not payable.

                               SUMMA INDUSTRIES

  FIRST:     The name of this corporation is "Summa Industries."

  SECOND:     The address of the registered office of the corporation in the
State of Delaware is 15 E. North Street, in the City of Dover, County of Kent,
19901, and the name of its registered agent at that address is PARACORP
INCORPORATED.

  THIRD:     The name and mailing address of the incorporator of the corporation

         Suite 500
         Torrance, California 90503

  FOURTH:     The purpose of the corporation is to engage in any lawful act or
activity for which corporations may be organized under the General Corporation
Law of Delaware.

  FIFTH:     The corporation is authorized to issue 15,000,000 shares,
10,000,000 of which are designated "Common Stock," $0.001 par value, and
5,000,000 of which are designated "Preferred Stock," $0.001 par value.  The
Board of Directors is hereby authorized to fix or alter the rights, preferences,
privileges and restrictions granted to or imposed upon any series of Preferred
Stock, and the number of shares constituting any such series and the designation
thereof, or of any of them.  The Board of Directors is also authorized to
increase or decrease the number of shares of any series, prior or subsequent to
the issue of that series, but not below the number of shares of such series then
outstanding.  In case the number of shares of any series shall be so decreased,
the shares constituting such decrease shall resume the status which they had
prior to the adoption of the resolution originally fixing the number of shares
of such series.

  SIXTH:     In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to make, repeal, alter,
amend and rescind from time to time any or all of the bylaws of the corporation;
provided, however, that any bylaw amendment adopted by the Board of Directors
increasing or reducing the authorized number of directors or amending,
repealing, altering or rescinding Article III, Section 1 of the bylaws of the
corporation shall require a resolution adopted by the affirmative vote of not
less than sixty-six and two-thirds percent (66-2/3%) of the directors.  Any
bylaw amendment adopted by the stockholders increasing or reducing the
authorized number of directors or amending, repealing, altering or rescinding
Article III, Section 1 of the Bylaws of the corporation shall require the
approval of not less than sixty-six and two-thirds percent (66-2/3%) of the
total voting power of all outstanding shares of stock of the corporation
entitled to vote thereon.

  SEVENTH:     The number of directors of the corporation shall be fixed from
time to time by a bylaw or amendment thereof duly adopted by the Board of
Directors.

  The Board of Directors shall be classified with respect to the time for which
they severally hold office into three classes designated Class I, Class II and
Class III, as nearly equal in number as possible.  Each director shall serve for
a term ending on the date of the third annual meeting of stockholders following
the annual meeting at which the director was elected; provided, however, that
the directors first elected to Class I shall serve for a term ending on the
annual meeting next following the end of fiscal year 1998, the directors first
elected to Class II shall serve for a term ending on the annual meeting next
following the end of fiscal year 1999 and the directors first elected to Class
III shall serve for a term ending on the annual meeting next following the end
of fiscal year 2000.

                                       8
<PAGE>
 
Notwithstanding the foregoing, each director shall serve until his successor
shall have been duly elected and qualified, unless he shall resign, become
disqualified, disabled or shall otherwise be removed.

  At each annual election, directors chosen to succeed those whose terms then
expire shall be of the same class as the directors they succeed, unless by
reason of any intervening changes in the authorized number of directors, the
Board of Directors shall designate one or more directorships whose term then
expires as directorships of another class in order more nearly to achieve
equality of number of directors among the classes.

  Notwithstanding the rule that the three classes shall be as nearly equal in
number of directors as possible, in the event of any change in the authorized
number of directors, each director then continuing to serve as such shall
nevertheless continue as a director of the class of which he is a member until
the expiration of his current term, or his prior death, resignation or removal.
If any newly created directorship may, consistently with the rule that the three
classes shall be as nearly equal in number of directors as possible, be
allocated to any class, the Board of Directors shall allocate it to that of the
available class whose term of office is due to expire at the earliest date
following such allocation.

  EIGHTH:     No stockholder will be permitted to cumulate votes in any election
of directors.

  NINTH:     Special meetings of the stockholders of this corporation for any
purpose or purposes may be called at any time upon the request in writing of a
majority of the Board of Directors or by the Chairman of the Board or the
President of the corporation. Any such request shall state the purpose or
purposes of the proposed meeting. As soon as reasonably practicable after
receipt of such a request, written notice of such meeting, stating the place,
date and hour of the meeting, shall be given to each stockholder entitled to
vote at such meeting. Special meetings may not be called other than as provided
in this ARTICLE NINTH.

  TENTH:   Stockholders of the corporation shall take action by meetings held
pursuant to this certificate of incorporation and the bylaws.  Stockholders may
not take any action by written consent in lieu of a meeting.  Meetings of
stockholders may be held within or outside of the State of Delaware, as the
bylaws may provide.  The books of the corporation may be kept (subject to any
provision contained in the statute) outside the State of Delaware at such place
or places as may be designated from time to time by the Board of Directors or in
the bylaws of the corporation.

  ELEVENTH:     The corporation reserves the right to amend, alter, change or
repeal any provision contained in this certificate of incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred on
stockholders herein are granted subject to this reservation.  Notwithstanding
the foregoing, the provisions set forth in ARTICLES SIXTH, SEVENTH, TENTH,
TWELFTH and this ARTICLE ELEVENTH may not be repealed or amended in any respect
unless such repeal or amendment is approved by the affirmative vote of not less
than sixty-six and two-thirds percent (66-2/3%) of the total voting power of all
outstanding shares of stock of this corporation entitled to vote thereon, unless
such amendment or repeal has been previously approved by the vote of not less
than sixty-six and two-thirds percent (66-2/3%) of the members of the Board of
Directors, in which case those Articles of this certificate of incorporation may
be so amended or repealed by a vote of not less than a majority of the total
voting power of all outstanding shares of stock of the corporation entitled to
vote thereon.

  TWELFTH:     A director of the corporation shall not be personally liable to
the corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the Delaware General Corporation
Law, or (iv) for any transaction from which the director derived any improper
personal benefit.  If the Delaware General Corporation Law is hereafter amended
to authorize, with the approval of a corporation's stockholder, further
reductions in the liability of the directors of a corporation for breach of
fiduciary duty, then a director of the corporation shall not be liable for any
such breach to the fullest extent permitted by the Delaware General Corporation
Law as so amended.  Any repeal or modification of the foregoing provisions of
this

                                       9
<PAGE>
 
ARTICLE TWELFTH by the stockholders of the corporation shall not adversely
affect any right or protection of a director of the corporation existing at the
time of such repeal or modification.

  THIRTEENTH:     Elections of directors need not be by written ballot unless
the bylaws of the corporation shall so provide.

  THE UNDERSIGNED, being the incorporator hereinbefore named, for the purpose of
forming a corporation to do business both within and without the State of
Delaware, and in pursuance of the Delaware General Corporation Law, does hereby
make this Certificate, hereby declaring and certifying that this is my act and
deed and the facts herein stated are true, and accordingly have hereunto set my
hand this __ day of __________ 1998.

record at the time of giving of the notice provided for in this Bylaw, who shall
be entitled to vote at such meeting and who complies with the notice procedures
set forth in this Bylaw.

  For business to be properly brought before any meeting by a stockholder

this Section 10.  The presiding officer of the meeting shall, if the facts
warrant determine and declare to the meeting that business was not properly
brought before the meeting and in accordance with the procedures prescribed by
this Section 10, and if such person should so determine, such person shall so
declare to the meeting and any such business not properly brought before the
meeting shall not be transacted.  Notwithstanding the foregoing provisions of
this Section 10, a stockholder shall also comply with all applicable
requirements of the Securities Exchange Act of 1934, as amended, and the rules
and regulations thereunder with respect to the matters set forth in this Section

  Section 1.  Unless otherwise restricted by the certificate of incorporation,
the number of directors which shall constitute the whole Board of Directors
shall be determined by resolution of the Board of Directors or by the
stockholders at the annual meeting of the stockholders, except as provided in
Section 2 of this Article, and each director elected shall hold office until his
successor is elected and qualified.  Directors need not be stockholders.

  Section 2.  Vacancies and new created directorships resulting from any
increase in the authorized number of directors may be filled by a majority of
the directors then in office, though less than a quorum, or by a sole remaining
director, and the directors so chosen shall hold office until the next annual
election and until their successors are duly elected and shall qualify, unless
sooner displaced.  If there are no directors in office, then an election of
directors may be held in the manner provided by statute.  If, at the time of
filling any vacancy or any newly created directorship, the directors then in
office shall constitute less than a majority of the whole Board of Directors (as
constituted immediately prior to any such increase), the Court of Chancery may,
upon application of any stockholder or stockholders holding at least ten percent
(10%) of the total number of the shares at the time outstanding having the right
to vote for such directors, summarily order an election to be held to fill any
such vacancies or newly created directorships or to replace the directors chosen
by the directors then in office.

  Section 3.  The business of the corporation shall be managed by or under the
direction of its Board of Directors which may exercise all such powers of the
corporation and do all such lawful acts and things as are not by statute or by
the certificate of incorporation or by these Bylaws directed or required to be
exercised or done by the stockholders.

  Section 4.  The Board of Directors of the corporation may hold meetings, both
regular and special, either within or without the State of Delaware.

be held at such time and place as shall be fixed by the vote of the stockholders
at the annual meeting, and no notice of such meeting shall be necessary to the
newly elected directors in order legally to constitute the meeting, provided a
quorum shall be

                                      13
<PAGE>
 
present. In the event of the failure of the stockholders to fix the time or
place of such first meeting of the newly elected Board of Directors, or in the
event such meeting is not held at the time and place so fixed by the
stockholders, the meeting may be held at such time and place as shall be
specified in a notice given as hereinafter provided for special meetings of the
Board of Directors or as shall be specified in a written waiver signed by all of
the directors.

president or secretary in like manner and on like notice on the written request
of the sole director.

  Section 8.  At all meetings of the Board of Directors a majority of the
directors shall constitute a quorum for the transaction of business, and the act
of a majority of the directors present at any meeting at which there is a quorum
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute or by the certificate of incorporation.  If a
quorum shall not be present at any meeting of the Board of Directors, the
directors present thereat may adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present.

  Section 9.  Unless otherwise restricted by the certificate of incorporation or
these Bylaws, any action required or permitted to be taken at any meeting of the
Board of Directors or of any committee thereof may be taken without a meeting,
if all members of the Board of Directors or committee, as the case may be,
consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the Board of Directors or committee.

  Section 10. Unless otherwise restricted by the certificate of incorporation or
these Bylaws, members of the Board of Directors, or any committee designated by
the Board of Directors, may participate in a meeting of the Board of Directors,
or any committee, by means of conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
each other, and such participation in a meeting shall constitute presence in
person at the meeting.

                            COMMITTEES OF DIRECTORS

  Section 11. The Board of Directors may, by resolution passed by a majority of
the whole Board of Directors, designate one or more committees, each committee
to consist of one or more of the directors of the corporation.  The Board of
Directors may designate one or more directors as alternate members of any
committee, who may replace any absent or disqualified member at any meeting of
the committee.

members thereof present at any meeting and not disqualified from voting, whether
or not he or they constitute a quorum, may unanimously appoint another member of
the Board of Directors to act at the meeting in the place of any such absent or
disqualified member.

  Any such committee, to the extent provided in the resolution of the Board of
Directors, shall have and may exercise all the powers and authority of the Board
of Directors in the management of the business and affairs of the corporation
and may authorize the seal of the corporation to be affixed to all papers which
may require it, but no such committee shall have the power or authority in
reference to amending the certificate of incorporation, adopting an agreement of
merger or consolidation, recommending to the stockholders the sale, lease or
exchange of all or substantially all of the corporation's property and assets,
recommending to the stockholders a dissolution of the corporation or a
revocation of a dissolution or amending the bylaws of the corporation; and,
unless the resolution or the certificate of incorporation expressly so provide,
no such committee shall have the power or

                                      14
<PAGE>
 
authority to declare a dividend or to authorize the issuance of stock. Such
committee or committees shall have such name or names as may be determined from
time to time by resolution adopted by the Board of Directors.

  Section 12. Each committee shall keep regular minutes of its meetings and
report the same to the Board of Directors when required.

                           COMPENSATION OF DIRECTORS

  Section 13. Unless otherwise restricted by the certificate of incorporation
or these Bylaws, the Board of Directors shall have the authority to fix the
compensation of directors.  The directors may be paid their expenses, if any, of
attendance at each meeting of the Board of Directors and may be paid a fixed sum
for attendance at each meeting of the Board of Directors or a stated salary as
director.  No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor.  Members
of special or standing committees may be allowed like compensation for attending
committee meetings.

                             REMOVAL OF DIRECTORS

notice, but such notice may be given in writing, by mail, addressed to such
director or stockholder, at his address as it appears on the records of the
corporation, with postage thereon prepaid, and such notice shall be deemed to be
given at the time when the same shall be deposited in the United States mail.
Notice to directors may also be given by telegram.

  Section 2.  Whenever any notice is required to be given under the provisions
of the statutes or of the certificate of incorporation or of these Bylaws, a

directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining

                                      18
<PAGE>
 
any property of the corporation, or for such other purposes as the directors
shall think conducive to the interest of the corporation, and the directors may

                                INDEMNIFICATION

  Section 6.  The corporation shall, to the fullest extent authorized under the
laws of the State of Delaware, as those laws may be amended and supplemented
from time to time, indemnify any director made, or threatened to be made, a
party to an action or proceeding, whether criminal, civil, administrative or
investigative, by reason of being a director of the corporation or a predecessor
corporation or, at the corporation's request a director or officer of another
corporation, provided, however, that the corporation shall indemnify any such
agent in connection with a proceeding initiated by such agent only if such
proceeding was authorized by the Board of Directors of the corporation.  The
indemnification provided for in this Section 6 shall: (i) not be deemed
exclusive of any other rights to which those indemnified may be entitled under
any bylaw, agreement or vote of stockholders or disinterested directors or
otherwise, both as to action in their official capacities and as to action in
another capacity while holding such office, (ii) continue as to a person who has
ceased to be a director, and (iii) inure to the benefit of the heirs, executors
and administrators of such a person.  The corporation's obligation to provide
indemnification under this Section 6 shall be offset to the extent of any other
source of indemnification or any otherwise applicable insurance coverage under a
policy maintained by the corporation or any other person.

  Expenses incurred by a director of the corporation in defending a civil or
criminal action, suit or proceeding by reason of the fact that he is or was a
director of the corporation (or was serving at the corporation's request as a
director or officer of another corporation) shall be paid by the corporation in
advance of the final disposition of such action, suit or proceeding upon receipt
of an undertaking by or on behalf of such director to repay such amount if it
shall ultimately be determined that he is not entitled to be indemnified by the
corporation as authorized by relevant sections of the General Corporation Law of
Delaware.  Notwithstanding the foregoing, the corporation shall not be required
to advance such expenses to an agent who is a party to an action, suit or
proceeding brought by the corporation and approved by a majority of the Board of
Directors of the corporation which alleges willful misappropriation of corporate
assets by such agent, disclosure of confidential information in violation of
such agent's fiduciary or contractual obligations to the corporation or any
other willful and deliberate breach in bad faith of such agent's duty to the
corporation or its stockholders.

  The foregoing provisions of this Section 6 shall be deemed to be a contract
between the corporation and each director who serves in such capacity at any
time while this bylaw is in effect, and any repeal or modification thereof shall
not affect any rights or obligations then existing with respect to any state of
facts then or theretofore existing or any action, suit or proceeding theretofore
or thereafter brought based in whole or in part upon any such state of facts.

                                      19
<PAGE>
 
  The Board of Directors in its discretion shall have power on behalf of the
corporation to indemnify any person, other than a director, made a party to any
action, suit or proceeding by reason of the fact that he, his testator or
intestate, is or was an officer or employee of the corporation.

  To assure indemnification under this Section 6 of all directors, officers and
employees who are determined by the corporation or otherwise to be or to have
been "fiduciaries" of any employee benefit plan of the corporation which may
exist from time to time, Section 145 of the General Corporation Law of Delaware
shall, for the purposes of this Section 6, be interpreted as follows: an "other
enterprise" shall be deemed to include such an employee benefit plan, including
without limitation, any plan of the corporation which is governed by the Act of
Congress entitled "Employee Retirement Income Security Act of 1974," as amended
from time to time;  the corporation shall be deemed to have requested a person
to serve an employee benefit plan where the performance by such person of his
duties to the corporation also imposes duties on, or otherwise involves services
by, such person to the plan or participants or beneficiaries of the plan; excise
taxes assessed on a person with respect to an employee benefit plan pursuant to
such Act of Congress shall be deemed "fines."

                                 ARTICLE VIII

                                  AMENDMENTS

  Section 1.  Subject to the certificate of incorporation of the corporation,
these Bylaws may be altered, amended or repealed or new bylaws may be adopted by
the stockholders or by the Board of Directors, when such power is conferred upon
the Board of Directors by the certificate of incorporation, at any regular
meeting of the stockholders or of the Board of Directors or at any special
meeting of the stockholders or of the Board of Directors if notice of such
alteration, amendment, repeal or adoption of new bylaws be contained in the
notice of such special meeting.  If the power to adopt, amend or repeal bylaws
is conferred upon the Board of Directors by the certificate of incorporation, it
shall not divest the power of the stockholders to adopt, amend or repeal bylaws.
