                                   ARTICLE II

                       ARTICLES OF INCORPORATION, BYLAWS,

Effective Date, to provide that the total number of all classes of capital stock
which the Surviving Corporation shall have authority to issue shall be 1,000

Incorporation of the Surviving Corporation until further amended or repealed in
accordance with the provisions thereof and of applicable law.

          2.2  The Bylaws of LexaLite as in effect immediately prior to the

                                  ARTICLE III

                       TREATMENT OF SHARES OF EACH OF THE
                            CONSTITUENT CORPORATIONS

                                 3.1  On the Effective Date:

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

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

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

          (d)  Each share of Subsidiary's Common Stock outstanding immediately
prior to the Merger shall, by virtue of the Merger and without any action on the
part of the holder thereof, be converted into and become one fully paid and
nonassessable share of Common Stock, $1.00 par value, of the Surviving
Corporation.

                                       3

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

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

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

Reorganization Agreement at any time before or after adoption and approval
hereof by the stockholders of LexaLite or the shareholders of Subsidiary, or
both, but not later than the Effective Date.  In the event of such termination,

liability on the part of Summa, Subsidiary or LexaLite, or the Board of
Directors or shareholders, or stockholders, as the case may be, except as
provided in Section 4.4 hereof.

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

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

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