PARTICIPATION

3.1 Designation by Deferral Authority . The Deferral Authority in its sole discretion shall designate those Employees or Directors who are to be eligible to participate in the Plan with respect to Deferrals for a particular Plan Year or with respect to a particular Deferrable Amount or Amounts. Designating an individual as eligible to participate in the Plan for a particular Plan Year or with respect to a particular Deferrable Amount shall not require the Deferral Authority to designate such individual for any subsequent Plan Year or with respect to any subsequent Deferrable Amounts. The designation of eligibility by the Deferral Authority may be made in such manner as determined by the Deferral Authority, including, without limitation, establishment of criteria such as compensation level or level or authority.

3.2 Deferral Elections .

(a) An eligible Employee or Director shall not become a Participant in the Plan unless and until he or she has executed and delivered to the Committee a Deferral election, including any forms or agreements as may be prescribed by the Committee, and the Committee shall have accepted such Deferral election and/or additional forms or agreements. Participation in the Plan and any elections made by a Participant, including Deferral elections and elections as to form of distribution under Article VII, is conditioned on the Participant executing an agreement with the Company, in a manner prescribed by the Committee, relating to the Company’s right of repurchase of Company Stock (to the extent applicable) and such other matters as the Committee shall prescribe. To initially participate in the Plan, the Employee or Director must submit his or her Deferral election, including any forms or agreements prescribed by the Committee, during the applicable Deferral election period established by the Committee. Effective for Deferrals on or after January 1, 2005, the last day of the Deferral election period for any Deferrable Amount other than “performance-based compensation” (as defined below) shall be no later than the last day of the calendar year prior to the first calendar year during which the Employee or Director performs services for which such Deferral Amount is earned. Beginning with the Deferral election made in the 2003 Plan Year for Deferrable Amounts received during calendar year 2004, the Participant’s election shall be carried forward automatically to future Plan Years for which the Participant is eligible to participate unless, during the applicable Deferral election period for such future Plan Years, the Participant elects to modify or cancel the prior election under procedures established by the Committee. In addition to amounts deferred pursuant to a Deferral election, additional Deferrals may be credited to a Participant’s Account pursuant to the terms of an offer letter with an Employee made at the time of commencement of employment with the

Company, as determined and approved by the Deferral Authority in its sole discretion. Furthermore, the Committee may, to the extent consistent with satisfying Code Section 409A, permit an Employee or Director to make a Deferral Election within 30 days of the date such Employee or Director first becomes eligible to participate in the Plan, as indicated by the effective date of his status change in the Plan’s records. Such a Deferral election shall be with respect to compensation earned for services performed after the election.

(b) If a Deferrable Amount constitutes “performance-based compensation,” then the Committee may, but need not, delay the last day of the Deferral election period. The last day of the Deferral election period with respect to any Deferrable Amount which is considered to be performance-based compensation shall be no later than six months before the end of the service period over which such Deferrable Amount is earned. For this purpose, “performance-based compensation” means compensation where the amount of or entitlement to the compensation is contingent on the satisfaction of pre-established written performance criteria relating to a performance period of at least twelve consecutive months, provided that performance-based compensation does not include any amount that will be paid regardless of performance, or based upon a level of performance that is substantially certain to be met at the time the criteria is established.
