event, as the case may be, make a determination as to whether a Hardship exists,

and the amount, if any, to which the Participant may be entitled (which amount
shall not exceed the amount reasonably necessary to satisfy the need resulting
from the Unforeseeable Emergency (and any amounts necessary to pay any Federal,
state, local, or foreign income taxes or penalties reasonably anticipated to
result from the distribution)), and pay such amount on such 90th day, provided,
however, that pursuant to Treasury Regulation section 1.409A-3(d), if the
Participant is unable (due to circumstances beyond the control of the
Participant) to timely provide necessary information, the Committee’s
determination and payment shall be made during the first calendar year in which
calculation of the payment amount is administratively practicable.”

9. The Plan is hereby amended by adding a new Section 11.15 to read as follows:

“If for any reason, such as imprecision in drafting, any provision of the Plan
does not accurately reflect its intended establishment of an exemption from (or
compliance with) Code Section 409A, as demonstrated by consistent
interpretations or other evidence of intent, such provision shall be considered
ambiguous as to its exemption from (or compliance with) Code Section 409A and
shall be interpreted by the Committee in a manner consistent with such intent.
Each/payment made under the Plan shall be designated as a “separate payment”
within the meaning of Code Section 409A.”

10. Except as hereinabove amended and modified, the Plan shall remain in full
force and effect.
