the Committee.  Vacancies on the Committee, howsoever caused,
shall be filled by the Board.

shall have authority:

     (a)  To determine the Employees to whom and the time or
times
          at which Options shall be granted and the number of

     (b)  To interpret the Plan;

     (c)  To prescribe, amend, and rescind rules and regulations
          relating to the Plan;




     (d)  To authorize any person to execute on behalf of the
          Company any instrument required to effectuate the grant
          of an Option granted by the Committee; and

     (e)  To make all other determinations deemed necessary or
          advisable for the administration of the Plan.

     4.4  The decisions, determinations, and interpretations of
the Committee shall be final and binding on all Optionees and any
other holders of any Option granted under the Plan.  No member of
the Committee shall be liable for any action or determination
made
in good faith with respect to the Plan or any Option granted
under
the Plan.

                             SECTION V
                      TERMS OF STOCK OPTIONS

     5.1  The Option price for Shares to be issued pursuant to
any
Option granted under the Plan shall be last sale price as
reported
by the Automated Quotation System of the National Association of
Securities Dealers on the date of the grant.  In the event a sale
shall not have been effected on the date of the grant, the last
sale price first reported prior to the date of grant shall be
used.

     5.2  The date of grant of an Option under the Plan shall,
for
all purposes, be the date on which the Committee makes a
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.

     5.3  The Committee shall fix the term or duration of all
Options under this Plan provided that no term shall exceed five
(5) years after the date on which the Option was granted. Options
granted under the Plan shall not be transferable other than by
will or the laws of descent and distribution and shall be
exercisable during the Optionee's lifetime only by the Optionee.

     5.4  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 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, 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.

     5.5  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.



     5.6  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.

     5.7  No Option granted under the Plan shall be exercisable
while there is outstanding any other Option granted to the
Optionee at an earlier date.  For this purpose, an Option which
has not been exercised in full is outstanding until the
expiration of the period which under its initial terms could have
been exercised.  The cancellation of an earlier Option will not
enable a subsequent Option to be exercised any sooner.

                            SECTION VI
                        EXERCISE OF OPTION

     6.1  An Option shall be deemed to be exercised when written
notice of such exercise has been given to the Company in
accordance with the terms of the Option by the person entitled to
exercise the Option and full payment of the shares with respect
to
which the Option is exercised has been received by the Company. 
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 with respect 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 VII of the Plan.

                            SECTION VII
                   REORGANIZATION OF THE COMPANY

     7.1  In the event of any stock dividend, stock split,
combination of shares, or other change in the capitalization of
the Company, appropriate adjustment shall be made in the number
and kind of shares as to which Options may be granted and as to
which Options or portions thereof then outstanding and
unexercised
shall be exercisable and in the Option price thereof.

     7.2  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.

     For purposes of the Plan, a "Change in Control" shall mean
the happening of any of the following events:

     (a)  any Person is or becomes the "beneficial owner" (within
          the meaning of Rule 13d-3 promulgated under Section 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

     (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.
