                                    EXHIBIT A

     1.  The definition of "Financial Hardship" in Section 2 is amended so that
         it reads in its entirety as follows:

         "'Financial Hardship' means an "unforeseeable emergency" as defined
         under Section 409A of the Code, that is, a severe financial hardship
         resulting from an event or expenditure described in or contemplated by
         Section 1.409A-3(i)(3) of the Treasury Regulations, as determined by
         the Committee."

     2.  The definition of "Specified Employee" in Section 2 is amended so that
         it reads in its entirety as follows:

         "'Specified Employee' means an individual who is determined by the
         Company to be a specified employee as defined in subsection
         (a)(2)(B)(i) of Section 409A. The Company may, but need not, elect in
         writing, subject to the applicable limitations under Section 409A of
         the Code, any of the special elective rules prescribed in Section
         1.409A-1(i) of the Treasury Regulations for purposes of determining
         "specified employee" status. Any such written election shall be deemed
         part of the Plan."

     3.  Section 2 is further amended to add the follow paragraph following the
         definition of "Subsidiary":

         "For purposes of the Plan, all references to termination of employment,
         retirement, separation from service and similar or correlative terms
         shall mean a "separation from service" (as defined at Section
         1.409A-1(h) of the Treasury Regulations) from the Company and from all
         other corporations and trades or businesses, if any, that would be
         treated as a single "service recipient" with the Company under Section
         1.409A-1(h)(3) of the Treasury Regulations."

     4.  Section 5.2 is amended to read in its entirety as follows:

         "5.2 Mandatory Deferral. If a Participant's Bonus is $10,000 or more,
         twenty percent of such Bonus shall be deferred into a Phantom Stock
         Unit Account in accordance with the provisions of Section 6.1(b),
         unless the Committee in its sole discretion, not later than the date on
         which the Participant first has a "legally binding right" (as that term
         is used in the Treasury Regulations under Section 409A of the Code),
         conditional or otherwise, to such Bonus, or at such later time as would
         be permitted under applicable transition rules under Section 409A,
         determines a lower percentage (but not lower than ten percent) of such
         Bonus to be deferred into a Phantom Stock Unit Account; provided such
         determination shall be applied uniformly to all Participants. Subject
         to the provisions of Section 8.4, if a Bonus is less than $10,000 (and
         together with all amounts, if any, required to be aggregated with it
         under Section 1.409A-1(c) of the Treasury Regulations, is equal to or
         less than the amount eligible to be cashed out under Section
         1.409A-3(j)(4)(v) of the Treasury Regulations), the entire amount
         thereof shall be paid in a single lump sum cash payment immediately
         upon the determination thereof."


<PAGE>

     5.  Section 5.3 is amended so that the words "promptly following are
         replaced with the words "immediately upon".

     6.  A new Section 5.6 is added to read as follows:

         "5.6 Separate Payments. For purposes of Section 409A of the Code, each
         payment of any portion of a Bonus shall be treated as a separate
         payment. Without limiting the generality of the foregoing, the portion
         of any Bonus payable on a non-deferred basis in cash shall be treated
         as a payment separate from any payment under a Phantom Stock Unit."

     7.  Section 6.2(a) is amended to read in its entirety as follows:

         "(a) Distribution Date of Deferred Payment. Subject to the provisions
         of Sections 6.2(b), 6.2(c), 6.2(d) and 8.4, with respect to each
         Phantom Stock Unit Account of a Participant, the Participant shall be
         paid in cash in a lump sum the value of the Phantom Stock Units in his
         or her Phantom Stock Unit Account on a date (the "Distribution Date")
         that is the earlier of (i) the second anniversary of the Allocation
         Date, (ii) if the Participant at the relevant time is a Specified
         Employee, the date that is six months after his or her separation from
         service for any reason or upon his death if earlier; (iii) if the
         Participant at the relevant time is not a Specified Employee, the date
         of the Participant's separation from service for any reason; or (iv)
         immediately prior to a Change of Control that is a "change in control
         event" as defined as defined in Section 1.409A-3(i)(5) of the Treasury
         Regulations. The responsibility for determining whether a Change of
         Control is a "change in control event" as defined above shall rest with
         the Committee; PROVIDED, that in the absence of an express and
         reasonable determination to the contrary with respect to a Change of
         Control, the Committee shall be deemed to have determined that the
         Change of Control is a "change in control event" as so defined. The
         value of any Phantom Stock Unit Account shall be determined by
         multiplying the Fair Market Value of Company Stock on the Distribution
         Date by the number of Phantom Stock Units in the Phantom Stock Unit
         Account; provided, however, when value of a Participant's Phantom Stock
         Units is determined with reference to a Distribution Date which is the
         second anniversary of an Allocation Date referred to in clause (i) of
         the first sentence of this Section 6.2(a), such value shall be
         determined (A) with respect to Phantom Stock Unit awards made in
         respect of calendar year 2006, by multiplying the number of Phantom
         Stock Units in the Participant's Phantom Stock Unit Account by the
         higher of (x) the Fair Market Value of a share of Company Stock on
         March 5, 2009 and (y) the average of the closing price of a share of
         Company Stock on the New York Stock Exchange for each of the 10 trading
         days immediately following the day on which the Company files with the
         Securities and Exchange Commission its Form 10-K for 2008, and (B) with
         respect to Phantom Stock Unit awards made in respect of calendar years
         subsequent to 2006 by multiplying the number of Phantom Stock Units in
         the Participant's Phantom Stock Unit Account by the average of the
         closing price of a share of Company Stock for each of the 10 trading
         days immediately following the day on which the Company files with the
         Securities and Exchange Commission its Form 10-K for the calendar year
         immediately preceding the second anniversary of the applicable
         Allocation Date."

     8.  Section 6.2(b) is amended by inserting "and Section 1.409A-3(i)(3) of
         the Treasury Regulations" immediately after "Section 409A(a)(2)(B)(ii)
         of the Code."

     9.  Section 6.2(c) is amended by deleting the last sentence thereof and by
         replacing the words "Notwithstanding anything contained herein to the
         contrary" at the beginning of such Section with the following: "In the
         circumstances specified in Section 1.409A-3(j) of the Treasury
         Regulation as exceptions to the rule against acceleration, and only to
         the extent provided therein,"

     10. Section 8.13 is renumbered as Section 8.14 and a new Section 8.13 is
         amended to read as follows:

         "8.13 Compliance with Section 409A. In any case in which a Participant
         is party to, or participates in, another plan or agreement that would
         subject to the rules of Section 409A of the Code any amounts payable
         hereunder that would otherwise be exempt from Section 409A of the Code,
         such amounts shall, to the extent necessary to comply with Section 409A
         of the Code, be paid in accordance with the Section 409A-compliant
         provisions of such other plan or agreement."
