3. Administration

   The Committee will administer the Plan and will make all other

   will be final and binding upon Participants and their legal representatives
   and, in the case of deceased Participants, upon their executors,
   administrators, estates, beneficiaries, heirs and legatees. The terms and
   provisions of the Plan will be construed under and controlled by the law of
   the State of Delaware.

   eliminate an Award that would otherwise be payable to a Participant under the
   Plan.  In no event will the amount of an Award payable to a Participant for a
   year exceed $3.0 million.

between such Directors and shareholders of the Corporation.

2.  DEFINITIONS

          designated on a Beneficiary Designation Form by a Participant as

          the designated Beneficiary or Beneficiaries fail to survive the
          Participant or otherwise fail to take the Benefit, the Participant's
          Beneficiary is the Participant's surviving spouse or, if there is no
          surviving spouse, the Participant's estate.

     (b)  BENEFICIARY DESIGNATION FORM means a form acceptable to the Committee

          assets that may or must be used to satisfy a Deferred Cash Benefit.  A
          Deferred Cash Account will be credited with that portion of the
          Participant's Retainer Fee deferred as a Deferred Cash Benefit
          according to a Deferral Election Form and according to section 6 of

          amounts as provided under section 6(b) of this Plan.

          each Participant to reflect the status of his/her Deferred Stock
          Benefits under this Plan.  A Deferred Stock Account is established

          segregate assets or to identify assets that may or must be used to
          satisfy a Deferred Stock Benefit.  A Deferred Stock Account will be
          credited with that portion of the Participant's Retainer Fee deferred
          as a Deferred Stock Benefit according to a Deferral Election Form and
          according to sections 3 and 7 of this Plan.  A Deferred Stock Account
          will be credited periodically with amounts determined by the Committee
          under subsection 7(b) of this Plan.

          Cash Benefit.  If a Deferred Benefit has no Distribution Election Form

     (q)  ELECTION DATE means the date established by this Plan as the date
          before which a Participant must submit a valid Deferral Election Form

          individual who becomes a Participant during a Deferral Year, the date
          that he/she becomes a Participant. Despite the two preceding
          sentences, the Committee may set an earlier date as the Election Date
          for any Deferral Year.

     (r)  PARTICIPANT means a Director who is not simultaneously an employee of
          the Corporation.

3.  MINIMUM STOCK-BASED COMPENSATION

     Each Person who becomes a Participant after October 29, 1996 shall receive
at least 50 percent of his/her annual Retainer Fee in the form of Common Stock
Units.

4.  DEFERRAL ELECTION

     A deferral election is valid when a Deferral Election Form is completed,
signed by the Participant, and received by the Committee or its designee.
Deferral elections are governed by the provisions of this section.

     (a)  A Participant may elect a Deferred Benefit for any Deferral Year if
          he/she is a Participant at the beginning of that Deferral Year or
          becomes a Participant during the Deferral Year.

     (b)  Before each Deferral Year's Election Date, each Participant will be
          provided with a Deferral Election Form.  Subject to Section 3, a
          Participant may elect on or before the Election Date to defer until
          after Termination the receipt of all or part of his/her Retainer Fee
          for the Deferral Year in the form of a Deferred Stock Benefit or a
          Deferred Cash Benefit.

     (c)  A Participant may not elect to convert a Deferred Cash Benefit to a
          Deferred Stock Benefit or to convert a Deferred Stock Benefit to a
          Deferred Cash Benefit.

     (d)  Each Distribution Election Form is part of the Deferral Election Form
          on which it appears or to which it states that it is related.  The
          Committee may allow a Participant to file one Distribution Election
          Form for all of his/her Deferred Cash Benefits and one for all of
          his/her Deferred Stock Benefits.  The provisions of subsection 2(p)
          apply to any Deferred Benefit under this Plan if there is no operative
          Distribution Election Form for that Deferred Benefit.

     (e)  If it does so before the last business day of the Deferral Year, the
          Committee may reject any Deferral Election Form or any Distribution
          Election Form or both, and the Committee is not required to state a
          reason for any rejection.  The Committee may modify any Distribution
          Election Form at any time to the extent necessary to comply with any
          laws or regulations.  However, the Committee's rejection of any
          Deferral Election Form or any Distribution Election Form or the
          Committee's modification of any Distribution Election Form must be
          based upon action

                                      -3-
<PAGE>

          taken without regard to any vote of the Participant whose Deferral
          Election Form or Distribution Election Form is under consideration,
          and the Committee's rejections must be made on a uniform basis with
          respect to similarly situated Participants. If the Committee rejects a
          Deferral Election Form, the Participant must be paid the amounts
          he/she would then have been entitled to receive if he/she had not
          submitted the rejected Deferral Election Form.

     (f)  A Participant may not revoke a Deferral Election Form or a
          Distribution Election Form after the Deferral Year begins. Any
          revocation before the beginning of the Deferral Year is the same as a
          failure to submit a Deferral Election Form or a Distribution Election
          Form. Any writing signed by a Participant expressing an intention to
          revoke his/her Deferral Election Form or a related Distribution
          Election Form and delivered to the Committee or its designee before
          the close of business on the relevant Election Date is a revocation.

5.  EFFECT OF NO ELECTION

     A Participant who has not submitted a valid Deferral Election Form to the
Committee or its designee on or before the relevant Election Date may not defer
any part of the cash portion of his/her Retainer Fee for the Deferral Year under
this Plan.  In the case of a person who becomes a Participant after October 29,
1996 and who does not submit a valid Deferral Election Form on or before the
relevant Election Date, fifty percent of such Participant's Retainer Fee will
become a Deferred Stock Benefit pursuant to section 4 of this Plan.  The
Deferred Benefit of a Participant who submits a valid Deferral Election Form but
fails to submit a valid Distribution Election Form for that Deferred Benefit
before the relevant Election Date or who otherwise has no valid Distribution
Election Form for that Deferred Benefit is governed by section 2(p).

6.  DEFERRED CASH BENEFITS

     (a)  Deferred Cash Benefits will be set up in a Deferred Cash Account for
          each Participant and credited with investment returns as provided in
          section 6(b).  Deferred Cash Benefits are credited to the applicable
          Participant's Deferred Cash Account as of the day they would have been
          paid but for the deferral.

     (b)  A Participant may select one or more investment options approved by
          the Committee for his/her Deferred Cash Benefits.  Amounts will be
          credited to Deferred Cash Accounts to reflect the returns on such
          investment options at periods determined by the Committee.

7.  DEFERRED STOCK BENEFITS

     (a)  Deferred Stock Benefits will consist of Common Stock Units and will
          be set up in a Deferred Stock Account for each Participant. "Common
          Stock Unit" shall mean a book-entry unit equal in value to a share of
          Common Stock. Each Common Stock Unit will increase or decrease in
          value by the same amount and with the same frequency as the fair
          market value of a share of Common Stock. Each Deferred Stock Account
          will be credited on January 15th of each year (or, if such day is not
          a

                                      -4-
<PAGE>

          business day, on the next succeeding business day) with a quantity
          of Common Stock Units determined in accordance with this section based
          on the closing price of a share of Common Stock on the NYSE on the
          last trading day of the preceding calendar year.

     (b)  Each Deferred Stock Account will be credited each calendar quarter, on
          the date on which dividends are reinvested under the Corporation's
          dividend reinvestment and stock purchase plans (the "Investment
          Date"), with additional Common Stock Units, including fractional
          units, in a quantity equal to the quotient of the dividends payable on
          the quantity of shares in such account divided by the Stock Purchase
          Price.  "Stock Purchase Price" means the price obtained by averaging
          the daily high and low sales prices of a share of Common Stock on the
          NYSE for the twelve days immediately preceding the Investment Date on
          which shares of Common Stock are reported on the NYSE.

     (c)  If a trust is established under section 9(b), an electing Participant
          may advise the trustee under the governing trust agreement as to the
          voting of  shares of the Common Stock allocated to that Participant's
          separate account under the trust according to this subsection and
          provisions of the governing trust agreement.  Before each annual or
          special meeting of the Corporation's shareholders, the trustee under
          the governing trust agreement must furnish each Participant with a
          copy of the proxy solicitation and other relevant material for the
          meeting as furnished to the trustee by the Corporation, and a form
          addressed to the trustee requesting the Participant's confidential
          advice as to the voting of shares of the Common Stock allocated to
          his/her account as of the valuation date established under the
          governing trust agreement preceding the record date.

8.  DISTRIBUTIONS

     (a)  According to a Participant's Distribution Election Form, but subject
          to section 4(e), a Deferred Cash Benefit must be distributed in cash.
          Subject to section 4(e), a Deferred Stock Benefit will be distributed
          in shares of Common Stock corresponding to, and equal to the number
          of, the Common Stock Units credited to the Participant's Deferred
          Stock Account. However, cash must be paid in lieu of fractional shares
          of the Common Stock otherwise distributable.

     (b)  Deferred Cash Benefits will be paid in a lump sum unless the
          Participant's Distribution Election Form specifies payment of a
          Deferred Cash Benefit in installment payments over ten years. For a
          Deferred Cash Benefit payable in installments, investment returns
          under section 6(b) will continue to accrue on the unpaid balance of a
          Deferred Cash Account. Any lump-sum cash payment will be paid or
          installment payments will begin to be paid or delivery of Common Stock
          will be made no later than five business days after the Participant's
          Termination, unless a later post-Termination date is specified in a
          Participant's Distribution Election Form.

                                      -5-
<PAGE>

     (c)  Deferred Benefits may not be assigned by a Participant or Beneficiary.
          A Participant may use a Beneficiary Designation Form to designate one
          or more Beneficiaries for all of his/her Deferred Benefits; such
          designations are revocable.  Each Beneficiary will receive his/her
          portion of the Participant's Deferred Cash Account and Deferred Stock
          Account on February 15 of the year following the Participant's death
          unless the Beneficiary's request for a different distribution schedule
          is received before distributions begin and is approved at the
          Committee's sole discretion.  The Committee may require that multiple
          Beneficiaries agree upon a single distribution method.

     (d)  Upon the occurrence of a Change in Control resulting in a
          Participant's Termination,  the Corporation shall pay such
          Participant, on the fifth day following such Termination, cash in an
          aggregate amount equal to the value of such Participant's Deferred
          Cash Account and Deferred Stock Account on the date of the Change in
          Control, as determined using the higher of the closing prices of the
          Common Stock on the New York Stock Exchange on such date or the
          highest per-share price actually paid in connection with such Change
          in Control.  For purposes of this Plan, "Change in Control" shall mean
          a change in control of a nature that would be required to be reported
          in response to Item 6(e) of Schedule 14A of Regulation 14A promulgated
          under the Securities Exchange Act of 1934, as amended (the "Exchange
          Act"), whether or not the Corporation is then subject to such
          reporting requirement; provided, that, without limitation, such a
          change in control shall be deemed to have occurred if

               (A)  any person (as defined in Sections 13(d) and 14(d)
                    of the Exchange Act) (a "Person") is or becomes the
                    "beneficial owner" (as defined in Rule 13d-3 under the
                    Exchange Act), directly or indirectly, of securities of the
                    Corporation representing twenty percent (20%) or more of the
                    combined voting power of the Corporation's then outstanding
                    voting securities; provided, however, that for purposes of
                    this Agreement the term "Person" shall not include (i) the
                    Corporation or any of its subsidiaries, (ii) a trustee or
                    other fiduciary holding securities under an employee benefit
                    plan of the Corporation 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
                    Corporation in substantially the same proportions as their
                    ownership of stock of the Corporation; or

               (B)  the following individuals cease for any reason to constitute

9.  CORPORATION'S OBLIGATION

     (a)  The Plan is unfunded.  A Deferred Benefit is at all times solely a
          contractual obligation of the Corporation. A Participant and
          his/her Beneficiaries have no right, title or interest in the
          Deferred Benefits or any claim against them. Except according to
          section 9(b), the Corporation will not segregate any funds or
          assets for Deferred Benefits nor issue any notes or security for
          the payment of any Deferred Benefit.

     (b)  The Corporation may establish a grantor trust and transfer to that
          trust shares of the Corporation's common stock or other assets.  The
          governing trust agreement must require a separate account to be
          established for each electing Participant.  The governing trust
          agreement must also require that all Corporation assets held in trust
          remain at all times subject to the Corporation's judgment creditors.

10.  CONTROL BY PARTICIPANT

         A Participant has no control over Deferred Benefits except according to
his/her Deferral Election Forms, Distribution Election Forms, and Beneficiary
Designation Form.

11.  CLAIMS AGAINST PARTICIPANT'S DEFERRED BENEFITS

         A Deferred Cash Account and Deferred Stock Account relating to a
Participant under this Plan are not subject in any manner to anticipation,
alienation, sale, transfer, assignment, pledge, encumbrance, or charge, and any
attempt to do so is void.  A Deferred Benefit is not subject to attachment or
legal process for a Participant's debts or other obligations.  Nothing contained
in this Plan gives any Participant any interest, lien or claim against any
specific asset of the Company.  A Participant or his/her beneficiary has no
rights other than as a general creditor.
