12. Deferred Compensation—Section 409A of the Code.





     This Agreement is intended to meet the requirements of Section 409A of the Code
and shall be administered in a manner that is intended to meet those requirements
and shall be construed and interpreted in accordance with such intent. To the
extent that a payment, or the settlement or deferral thereof, is subject to
Section 409A of the Code, except as the Board of Directors and Employee otherwise
determine in writing, the payment shall be paid, settled or deferred in a manner
that will meet the requirements of Section 409A of the Code, including regulations
or other guidance issued with respect thereto, such that the payment, settlement or
deferral shall not be subject to the additional tax or interest applicable under
Section 409A of the Code. Any provision of this Agreement that would cause the
payment, settlement or deferral thereof to fail to satisfy Section 409A of the Code
shall be amended (in a manner that as closely as practicable achieves the original
intent of this Agreement) to comply with Section 409A of the Code on a timely basis,
which may be made on a retroactive basis, if permitted under the regulations and
other guidance issued under Section 409A of the Code. In the event additional
regulations or other guidance is issued under Section 409A of the Code or a court of
competent jurisdiction provides additional authority concerning the application of
Section 409A with respect to the payments described hereunder, then the provisions
regarding such payments shall be amended to permit such payments to be made at the

that is practicable and achieves the original intent of this Agreement.

items 4 and 6 above, shall be amended in its entirety to read as follows:

otherwise provided by a specific provision of this First Amendment, be and become
effective as of January 1, 2005.
