period following the date on which the election is made; provided, however, that
with respect to a payment at a specified time or pursuant to a fixed schedule
(within the meaning of Code Section 409A) the election must be made at least 12
months before the date the payment is scheduled to be paid; and provided,
further, that in the case of an election related to a payment not described in
Treasury Regulation section 1.409A-3(a)(2) (payment on account of disability),
(a)(3) (payment on account of death) or (a)(6) (payment on account of
unforseeable emergency), the payment with respect to which such election is made
must be deferred for a period of at least 5 years from the date the payment
would otherwise have been paid.”

“6.1 Within the 90-day period following the Termination Date with respect to a
Terminating Event, the corresponding amount attributable to Deferred Stock Units
credited to a Participant’s Subaccounts established hereunder shall be

as set forth below, except that in no event shall the Participant have the right
to designate the taxable year of the payment.”

Company of satisfactory evidence of a final determination by a court of
competent jurisdiction from which no appeal is or can be taken, or, in the event
that no litigation is pursued, the final determination by the United States
Internal Revenue Service, or analogous taxing authority of another jurisdiction,
that all or a portion of such Subaccount is currently taxable or taxable in any
prior year to the Participant, or a change in the tax laws of the United States,
or any other applicable jurisdiction, having the same effect (but only the
amount necessary to cover any such taxes, penalties and/or interest due to the
applicable taxing authority shall be distributed; provided, however, that an
event described in this Section 6.3(c) shall be a Terminating Event only if
permitted under Treasury Regulation section 1.409A-3(j)(4)(iv), (vii), or (xi).”
