       2.     Section 4.5 of the Original SERP is hereby amended to read as
follows:

--------------------------------------------------------------------------------

 

       4.5   Accounting for Deferred Compensation and other Benefits. The
Administrator shall continue to maintain an individual Account under the name of
each Participant under this Plan. Each Account shall be adjusted at least
quarterly to reflect (i) the earnings credited on and losses allocable to the
Basic Deferrals, Automatic Deferrals, Discretionary Deferrals, Matching
Contributions and Employer Discretionary Contributions pursuant to Section 7.2,
and (ii) any payment of amounts attributable to such adjusted Basic Deferrals,
Automatic Deferrals, Discretionary Deferrals, Matching Contributions and
Employer Discretionary Contributions under this Plan. Each such Account shall be
credited with earnings and/or losses computed pursuant to Section 7.2 in the
manner specified by Section 7.2. Each such Account shall also be debited at
least annually to reflect the Matching Contributions under Section 4.2 and
Employer Discretionary Contributions under Section 4.3, plus earnings thereon
and losses allocable thereto, if any, attributable to the investment of such
amounts, with respect to which the Participant becomes vested after December 31,
2004 under Section 4.4. The amounts specified by the preceding sentence shall be
credited to the Participant's account under the 2005 SERP, as defined in Section
2.1(h), at such time as those amounts become vested under Section 4.4, and at
such time or times as those amounts are adjusted for the earnings thereon and
the losses allocable thereto. In the sole discretion of the Administrator, more
than one Account may be established for each Participant to facilitate record
keeping convenience and accuracy. Each such Account shall be credited and
adjusted as provided in this Plan. Amounts credited to each such Account shall
be held with the general assets of the Employer that employs that Participant.

       Establishment and maintenance of a separate Account or Accounts for each
Participant shall not be construed as giving any person any interest in assets
of the Company or an Employer, or a right to payment other than as provided
hereunder. Each Account shall be maintained until all amounts credited to such
Account have been distributed in accordance with the terms and provisions of
this Plan.

       3.     Section 4.6 of the Original SERP is hereby amended to read as
follows:

       4.6   Plan Benefits.  Subject to the vesting provisions of Section 4.4

Discretionary Contributions with respect to which the Participant becomes vested
before January 1, 2005 under Section 4.4 credited to such Participant's Account,
plus earnings thereon and less losses allocable thereto, if any, attributable to
the investment of such amounts pursuant to Section 7.2. The aggregate amounts of
the Matching Contributions under Section 4.2 and Employer Discretionary
Contributions, if any, under Section 4.3, plus earnings thereon and less losses
allocable thereto, if any, attributable to the investment of such amounts, with
respect to which the Participant becomes vested after December 31, 2004 under
Section 4.4 shall be debited to the Participant's Account and shall be credited
to the Participant's account under section 4.5 of the 2005 SERP, as defined in

comply with the requirements of section 409A of the Code.

       4.     The second paragraph of Section 7.1 of the Original SERP is hereby
amended to read as follows:

       Notwithstanding the foregoing, in the discretion of the Employer, the
Employer's obligations hereunder may be satisfied from a grantor trust
established by the Employer, the terms of which shall be substantially similar
to the terms of the model trust issued by the Internal Revenue Service in
Revenue Procedure 92-64, from an escrow account established at a bank or trust
company, or from an insurance contract or contracts owned by the Employer.
Except as provided by the next sentence, the assets of any such trust, escrow
account and any such insurance policy shall continue for all purposes to be a
part of the general funds of the Employer, shall be considered solely a means to
assist the Employer to meet its contractual obligations under this Plan and
shall not create a funded account or security interest for the benefit of any
Participant under this Plan. The assets of the Benefit Reserve Trust established
in connection with the adoption of this Plan which are allocable to the amounts
(i) debited from the Participants' Accounts pursuant to Section 4.5 to reflect
the Matching Contributions under Section 4.2 and Employer Discretionary
Contributions under Section 4.3, plus earnings thereon and losses allocable
thereto, if any, attributable to the investment of such amounts, with respect to
which the Participants become vested after December 31, 2004 under Section 4.4,
and (ii) credited to the accounts of the Participants in the 2005 SERP, as
described in Section 2.1(h), shall be considered a means to assist the Employer
to meet its contractual obligations under the 2005 SERP with respect to those
amounts of benefits to be paid under the 2005 SERP. All such assets shall be
subject to the claims of the general creditors of the Employer in the event the
Employer is Insolvent.

       IN WITNESS WHEREOF, the Company, acting by and through its duly
authorized officers, has caused this Amendment No. 2 to be executed on the date
first above written.
