grant, the last sale price first reported prior to the date of
grant shall be used.

determination granting such Option.  Notice of the determination
shall be given to each Employee to whom an Option is so granted
within a reasonable time after the date of such grant.

(10) years after the date on which the Option was granted. 
Options granted under the Plan shall not be transferable other

exercisable during the Optionee's lifetime only by the Optionee.

     6.4  In the event that an Optionee should cease to be
employed by the Company for any reason other than death or
permanent disability, the Optionee shall have the right to
exercise the Option to the extent the Option was then exercisable
at any time within three (3) months after the termination of
employment; provided, however, if an Optionee's employment is
terminated voluntarily by the Optionee or is terminated because
of the Optionee's dishonesty, theft, 

                                3



embezzlement from the Company, willful violation of any rules of
the Company pertaining to the conduct of Employees or the
commission of a willful felonious act while an Employee, then any
Option or unexercised portion thereof granted to said Optionee
shall expire upon termination of employment.

     6.5  If an Optionee shall die while an Employee and shall
not have fully exercised the Option, an Option may be exercised
to the extent that the Optionee's right to exercise such Option
had accrued at the time of his death and had not previously been
exercised, at any time within one (1) year after the Optionee's
death by the executors or administrators of the Optionee or by
any person or persons who shall have acquired the Option directly
from the Optionee by bequest or inheritance.

     6.6  If an Optionee shall cease to be an Employee by reason
of a permanent disability (as determined by the Optionee
officially establishing his eligibility to receive Social
Security disability benefits), an Option may be exercised to the
extent that the Optionee's right to exercise such Option had
accrued immediately prior to said disability, and had not
previously been exercised, at any time within one (1) year from
the date such Optionee ceased being an Employee.

     6.7  The fair market value of Common Stock for which any
Option may be granted in any calendar year under the Plan shall
be in such amount as the Committee shall determine; provided,
however, that the aggregate fair market value of Common Stock for
which Options granted under the Plan (or any other incentive
stock option plan of the Company or any subsidiary) are first
exercisable in any one calendar year by an Optionee may not
exceed $100,000 (determined as of the date of grant).

                           SECTION VII
                        EXERCISE OF OPTION

     7.1  An Option shall be deemed to be exercised when written
notice of such exercise has been received by the Company in
accordance with the terms of the Option by the person entitled to
exercise the Option, and full payment for the Shares with respect
to which the Option is exercised has been received by the
Company.  Payment may be made (i) in cash, (ii) by delivering
Common Stock of the Company already owned by the Optionee, or
(iii) a combination of cash and Common Stock.  Until the issuance
of the stock certificates, no right to vote or receive dividends
or any other rights as a shareholder shall exist with respect to
the Shares as to which the Option has been exercised.  No
adjustment will be made for a dividend or other rights for which
a record date is established prior to the date the stock
certificates are issued, except as provided in Section VIII of
the Plan.

                           SECTION VIII
                  REORGANIZATION OF THE COMPANY

     8.1  If the shares of common stock of the Company shall be
changed into or exchanged for a different number or kind of
shares of stock or other securities of the Company or of another 

                                4





corporation (whether by reason of merger, consolidation,
recapitalization, reclassification, split-up, combination of
shares, or otherwise), or if the number of such shares of common
stock shall be increased through the payment of a stock dividend
or stock split, there shall be substituted for or added to each
share of common stock of the Company theretofore reserved for the
purposes of the Plan, whether or not such shares are at the time
subjects to outstanding options, the number and kind of shares of
stock or other securities into which each outstanding share of
common stock of the Company shall be so changed or for which it
shall be so exchanged, or to which each such share shall be
entitled, as the case may be.   Outstanding options shall also be
considered to be appropriately amended as to price and other
terms as may be necessary or appropriate to reflect the foregoing
events.  If there shall be any other change in the number or kind
of the outstanding shares of common stock of the Company, or of
any stock or other securities into which such common stock shall
have been changed, or for which it shall have been exchanged,
then if the Board of Directors shall in its sole discretion
determine that such change equitably requires an adjustment in
the number or kind or option price of the shares then reserved
for the purposes of the Plan, or in any option theretofore
granted or which may be granted under the Plan, such adjustment
shall be made by the Board of Directors and shall be effective
and binding for all purposes of the Plan.  In making any such
substitution or adjustment, pursuant to this Section 8.1,
fractional shares shall be ignored.

     8.2  Notwithstanding any other provision of the Plan to the
contrary, in the event of a Change in Control, Options
outstanding as of the date of such Change in Control and not then
exercisable and vested shall become fully exercisable and vested.

     13 of the Securities Exchange Act of 1934 (the "Exchange
     Act")), directly or indirectly, of securities of the Company
     (not including in the securities beneficially owned by such
     Person any securities acquired directly from the Company or
     its affiliates other than in connection with the acquisition
     by the Company or its affiliates of a business) representing
     20% or more of either the then outstanding shares of common
     stock of the Company or the combined voting power of the
     Company's then outstanding securities; or

          (b)  the following individuals cease for any reason to
     constitute a majority of the number of directors then
     serving:  individuals who, on August 2, 1996, constitute the
     Board and any new director (other than a director whose
     initial assumption of office is in connection with an actual
     or threatened election contest, including but not limited to
     a consent solicitation, relating to the election of
     directors of the Company) whose appointment or election by
     the Board or nomination for election by the Company's
     stockholders was approved by a vote of at least two-thirds
     (2/3) of the directors then still in office who either were
     directors on August 2, 1996 or whose appointment, election
     or nomination for election was previously so approved; or

                                5





          (c)  there is consummated a merger or consolidation of
     the Company (or any direct or indirect subsidiary of the
     Company) with any other corporation, other than (i) a merger
     or consolidation which would result in the voting securities
     of the Company outstanding immediately prior to such merger
     or consolidation continuing to represent (either by
     remaining outstanding or by being converted into voting
     securities of the surviving entity or any parent thereof),
     in combination with the ownership of any trustee or other
     fiduciary holding securities under an employee benefit plan
     of the Company, at least 80% of the combined voting power of
     the voting securities of the Company or such surviving
     entity or any parent thereof outstanding immediately after
     such merger or consolidation, or (ii) a merger or
     consolidation effected to implement a recapitalization of
     the Company (or similar transaction) in which no Person is
     or becomes the beneficial owner, directly or indirectly, of
     securities of the Company (not including in the securities
     beneficially owned by such Person any securities acquired
     directly from the Company or its subsidiaries other than in
     connection with the acquisition by the Company or its
     subsidiaries of a business) representing 20% or more of
     either the then outstanding shares of common stock of the
     Company or the combined voting power of the Company's then
     outstanding securities; or

          (d)  the stockholders of the Company approve a plan of
     complete liquidation or dissolution of the Company or there
     is consummated a sale or disposition by the Company of all
     or substantially all of the Company's assets, other than a
     sale or disposition by the Company of all or substantially
     all of the Company's assets to an entity, at least 80% of
     the combined voting power of the voting securities of which
     are owned by Persons in substantially the same proportions
     as their ownership of the Company immediately prior to such
     sale.

     For purposes of the above definition of Change in Control,
"Person" shall have the meaning set forth in Section 3(a)(9) of
the Exchange Act, as modified and used in Sections 13(d) and
14(d) thereof, except that such term shall not include (i) the
Company or any of its subsidiaries, (ii) a trustee or other
fiduciary holding securities under an employee benefit plan of
the Company or any of its subsidiaries, (iii) an underwriter
temporarily holding securities pursuant to an offering of such
securities, or (iv) a corporation owned, directly or indirectly,
by the stockholders of the Company in substantially the same
proportions as their ownership of stock of the Company.
