“The SIP Parity Account shall include the Participant’s Grandfathered Account, 2005-2009 Contribution Account and Post-2009 Contribution Account, as applicable, each of which shall include a “Deferral Election Sub-Account” for amounts credited pursuant to a Participant’s Deferral Election under Sections 4.1 and 4.2(a) (or the prior provisions of the Plan regarding deferrals by Participants), an “Employer Matching Sub-Account” for amounts that are credited pursuant to Section 4.2(b) and that are described in Section 3.1(q)(i), (ii) or (iv) (or the prior provisions of the Plan regarding Employer contributions), and a “Employer Core Contribution Sub-Account” for amounts that are credited pursuant to Section 4.2(b) and that are described in Section 3.1(q)(iii).”

3.The first sentence of Section 4.2(b) is amended and restated to read as follows:

An Eligible Employee who has made a Deferral Election and who reaches the Compensation Limitation or the Section 415 Limitation for a year and an Eligible Employee who has become Disabled and who is entitled to an Employer Excess Contribution pursuant to Section 3.1(q)(iii) shall have Employer Excess Contributions credited to his SIP Parity Account for the year as follows:”

4.Section 5.1(b) is amended and restated to read as follows:

Notwithstanding any other provision of the Plan to the contrary, including the provisions of Section 5.3 dealing with Subsequent Deferral Elections, the vested portion of a Participant’s 409A Account that consists of an Employer Core Contribution Sub-Account shall be paid to the Participant (or to the applicable Death Benefit Beneficiary or Beneficiaries of such Participant, as the case may be) in cash in a single lump sum distribution 60 days following the Participant’s (i) attainment of age 65, or (ii) death, whichever first occurs.”

5.A new final sentence is added to Section 11.1 to read as follows:
