Garcia for the purpose of conforming it to certain provisions of Internal Revenue Code Section 409A. The amendment prescribes a severance payment schedule in the event of Mr. Garcia's termination without "Cause," that seeks to avoid the imposition of an excise tax as contemplated by Internal Revenue Code Section 409A, and provides for the automatic amendment of the agreement upon adoption of final regulations such that severance payments made under the agreement are included in Mr. Garcia's gross income at the time of actual payment and are not included in his gross income and subject to the additional tax and interest that would be required by Section 409A prior to such actual payment.
