its entirety to read as follows:

         "SECTION 3.3. BASIC AND ADDITIONAL EXCESS DEFERRAL BENEFITS.

               (a) PRE-1996 EXCESS DEFERRAL BENEFITS. Prior to January 1, 1996,
certain Employees of the Company were permitted to elect to defer specified
amounts of salary and bonus of up to 7% of compensation (the "Basic Excess
Deferrals") which are credited to the Basic Excess Deferral Sub-Account
hereunder and in excess of 7% of compensation (the "Additional Excess
Deferrals") which are credited to the Additional Excess Deferral Sub-Account
hereunder. At the time the Basic and Additional Excess Deferrals were elected,
the Participant irrevocably designated the date of commencement of the payment
of such Excess Deferrals by choosing one of the following dates: (i) the date on
which he ceases to be an Employee of the Controlled Group, (ii) the date on
which he attains an age specified in the election form, or (iii) the earlier or
later of such dates.

               (b) POST-1999 EXCESS DEFERRAL BENEFITS. Each Participant
described in Section 2.14(c)(ii) may, prior to the first day of any Plan Year,
by completing an approved deferral election form, direct the Company to reduce
his Compensation for such Plan Year and, subject to Subsection (d) below,
subsequent Plan Years, by an amount equal to between 1% and 17% of his
Compensation for the Plan Year (in 1% increments). The first 7% of Compensation
deferred by a Participant will be classified as the Basic Excess Deferrals which
are credited to the Basic Excess Deferrals Sub-Account and Compensation deferred
in excess of 7% of Compensation will be classified as the Additional Excess
Deferrals and will be credited to the Additional Excess Deferral Sub-Account.

               (c) DEFERRAL PERIOD FOR POST-1999 EXCESS DEFERRAL BENEFITS. The
deferral election form shall also contain the Participant's irrevocable election
regarding the time of the commencement of payment of the Participant's entire
Basic and Additional Excess Deferral Sub-Accounts. The Participant may elect to
commence payment of such Sub-Accounts on (i) the date on which he ceases to be
an Employee of the Controlled Group, (ii) the date on which he attains an age
specified in the form, or (iii) the earlier or later of such dates.

               (d) EFFECT AND DURATION OF DEFERRAL ELECTION FOR POST-1999 EXCESS
DEFERRAL BENEFITS. Any direction by a Participant to defer Compensation under
Subsection (b) above shall be effective with respect to Compensation otherwise
payable to the Participant during the Plan Year for which the deferral election
form is effective, and the Participant shall not be eligible to receive such
Compensation. Instead, such amounts shall be credited to the Participant's Basic
or Additional Excess Deferral Sub-Account (as applicable). Any directions made
in accordance with Subsection (b) shall be irrevocable and shall remain in
effect for subsequent Plan Years unless changed or terminated by the Participant
for Plan Years commencing after such change or termination on the appropriate
form provided by the Plan Administrator, prior to the first day of any
subsequent Plan Year.

               (e) AUTOMATIC TERMINATION OF DEFERRAL ELECTION FOR POST-1999
EXCESS DEFERRAL BENEFITS. A Participant's direction to defer Compensation under
Subsection (b) shall automatically terminate on the earlier of the date on which
(i) the Participant ceases employment with the Employers, (ii) the Participant's
Employer is deemed Insolvent, (iii) the Participant ceases to satisfy the
requirements of Section 2.14(c)(ii), or (iv) the Plan is terminated. In
addition, the Plan Administrator may, in its sole and absolute discretion,
pursuant to nondiscriminatory rules adopted by the Plan Administrator, reduced
and/or cease the deferral of Compensation under Subsection (b) by one or more
Participants, to the extent deemed necessary or desirable in order to satisfy
the requirements of any applicable law (including, without limitation, federal
securities laws)."
