        5.  ANNUAL LIMITATION ON SHARES SUBJECT TO PLAN:  The maximum number of
shares of stock which may be issued in any fiscal year of the Corporation under
the Plan shall be 150,000 shares of Common Stock of the Corporation, which may 
consist in whole or in part of the authorized and unissued or reacquired
Common Stock of the Corporation.  Such number of shares shall be subject to
such adjustment as the Committee, in its discretion, deems appropriate to
reflect such events as stock dividends, stock splits, recapitalizations,
mergers, consolidations or reorganizations of or by the Corporation.  No
fractional shares shall be issued pursuant to the Plan.

        6.  PARTICIPANTS:  The Committee shall determine and designate from
time to time, in its sole discretion, those officers and other key employees of
the Corporation or any Subsidiary who may participate under the Plan
("Participants").  Subject to adjustment as provided in Paragraph 5, no
Participant may receive more than 60,000 shares of Common Stock under the Plan
in any fiscal year of the Corporation.

        7.  ANNUAL AWARDS:  Each year following the effective date of the Plan,
after the determination of employee bonuses, each Participant shall receive
that whole number of shares of Corporation's Common Stock as is closest to the
quotient of (i) the portion of the Participant's bonus which the Participant
has elected to designate to receive in Common Stock (by delivery to the
Corporation of an irrevocable election form, designating such portion in the
form of a percentage of total bonus, by November 15 of the prior year), divided
by (ii) the fair market value of the Corporation's Common Stock on November 1
of the year in which the election is made, or on such other date as the
Committee shall designate.  Each Participant's annual bonus for such year,
payable in cash, shall be reduced by the portion so designated to be received
in Common Stock.  The fair market value of the Corporation's Common Stock shall
be determined by the Committee and may be determined by taking the mean between
the highest and lowest quoted selling prices of the Corporation's stock on
any exchange or other market on which the shares of Common Stock of the
Corporation shall be traded on such date.

        8.  ALLOTMENT OF SHARES:  In the event that the number of shares as to
which Participants provide written designations pursuant to Paragraph 7 exceeds
the annual limitation set forth in Paragraph 5, each Participant's allotment
of shares shall be reduced on a pro rata basis so that such annual limitation
is not exceeded.

        9.  NON-TRANSFERABILITY OF STOCK RIGHTS:  No right to receive stock
under the Plan shall be transferable by a Participant otherwise than by will,
or by the laws of descent and distribution.

        10.  INVESTMENT PURPOSE:  If the Committee in its discretion determines
that as a matter of law such procedure is or may be desirable, it may require a
Participant, upon any acquisition of stock hereunder and as a condition to the
Corporation's obligation to deliver certificates representing such shares, to
execute and deliver to the Corporation a written statement, in form
satisfactory to the Committee, representing and warranting that the
Participant's acquisition of shares of stock shall be for such person's own
account, for investment and not with a view to the resale or distribution
thereof and that any subsequent offer for sale or sale of any such shares shall
be made either pursuant to (a) a Registration Statement on an appropriate form
under the Securities Act of 1933, as amended (the "Securities Act"), which
Registration Statement has become effective and is current with respect to the
shares being offered and sold, or (b) a specific exemption from the
registration requirements of the Securities Act, but in claiming such exemption
the Participant shall, prior to any offer for sale or sale of such shares,
obtain a favorable written opinion from counsel for or approved by the
Corporation as to 

                                     B-2

   3
the availability of such exemption.  The Corporation may endorse an appropriate
legend referring to the foregoing restriction upon the certificate or
certificates representing any shares issued or transferred to the Participant
under the Plan.

        11.  NO RIGHTS TO CONTINUED EMPLOYMENT:  Nothing contained in the Plan,
nor any action taken by the Committee hereunder, shall confer upon any
Participant any right with respect to continuation of employment by the
Corporation or a Subsidiary as an employee nor interfere in any way with the
right of the Corporation or a Subsidiary to terminate such person's employment
as an employee at any time with or without cause.

        12.  WITHHOLDING:  In the event that the Corporation or a Subsidiary
is required by applicable tax laws to withhold any amounts with respect to a
Participant's annual bonus, the Corporation or Subsidiary shall first
appropriately reduce the amount of the Common Stock portion of a Participant's
annual bonus, and then, if necessary, the cash portion of a Participant's
annual bonus, to reimburse it for such income tax withholding.  The Committee
may make such other arrangements with respect to income tax withholding as it
shall determine.

        13.  EFFECTIVENESS OF PLAN:  The Plan shall be effective as of November
1, 1993; provided that the stockholders of the Corporation approve the Plan
within 12 months of that date.

        14.  TERMINATION AND AMENDMENTS OF PLAN:  The Plan may be abandoned or
terminated at any time by the Board of Directors of the Corporation.  For the
purpose of conforming to any changes in applicable law or governmental
regulations, or for any other lawful purpose, the Board of Directors shall have
the right, with or without approval of the stockholders of the Corporation, to
amend or revise the terms of the Plan at any time; provided, however, that no
such amendment or revision shall increase the maximum annual number of shares
which are subject to the Plan (subject, however, to the provisions of Paragraph
5), change the class of persons eligible to be Participants under the Plan or
materially increase the benefits accruing to Participants under the Plan,
without approval or ratification of the stockholders of the Corporation.

        As adopted by the Board of Directors on November 1, 1993.
