 4. Section 3.10

 described below:

 
	
  

 	
  

 
	
  

 	
           (a)
  If, at the time of the

 Participant had such employment not been interrupted by Qualified Military
 Service.

 
	
  

 	
  

 
	
  

 	
           (b)
  Solely for the purposes

 employed
 through the entirety of such period as an Eligible Employee at his regular
 rate of wages or salary in effect (including any contractual holiday,
 vacation or sick pay, contractual bonuses and other contractual direct
 remuneration) immediately prior to the commencement of such Qualified
 Military Service.

 Employer or an Affiliate within the time his reemployment rights are

           (e)

 Contributions described in paragraph (c) above, the Employer shall contribute
 for allocation to his Employer Matching Contributions Account an amount equal
 to the Employer Matching Contributions that would have been made for his

 (1)

 	
 if a
 Participant in Qualified Military Service elects to receive a distribution
 from the Plan on account of his severance from employment pursuant to Section

 Sections 5.9(c) – (e), a Participant or Beneficiary who would have been
 required to receive required minimum distributions for 2009 but for the
 enactment of Code Section 401(a)(9)(H) (“2009 RMDs”), and who would have
 satisfied that requirement by receiving distributions that are (1) equal to
 the 2009 RMDs or (2) one or more payments in a series of substantially equal
 distributions (that include the 2009 RMDs) made at least annually and
 expected to last for the life (or life expectancy) of the Participant, the
 joint lives (or joint life expectancy) of the Participant and the
 Participant’s designated Beneficiary, or for a period of at least 10 years
 (“Extended 2009 RMDs”), will receive those distributions for 2009 unless the
 Participant or Beneficiary chooses not to receive such distributions.
 Participants and Beneficiaries described in the preceding sentence will be
 given the opportunity to elect to stop receiving the distributions described
 in the preceding sentence. Further, and notwithstanding Section 5.11(b)(1),
 for purposes of the direct rollover provisions of Section 5.11, 2009 RMDs and

 Plan’s administrative procedures) in effect on the first day of the calendar
 quarter during which the loan is applied for; shall be repaid in accordance
 with a reasonable repayment schedule requiring substantially level payments
 of principal and interest; and shall be evidenced by a written promissory
 note setting forth the terms of the loan. A Participant may prepay the entire
 outstanding loan balance without penalty. Except for an outstanding loan upon
 a Participant’s retirement, Total and Permanent Disability, termination of

 Participant Individual Account among the separate Investment Options in which
 each sub-account is invested and transferred to a segregated loan account
 maintained in his name. The loan amount shall be withdrawn from the vested
 portions of the sub-accounts within the Individual Account in such order as
 the Committee shall determine. Within each sub-account, the loan amount shall
 be withdrawn from the separate Investment Options on a pro-rata basis based
 on the Participant’s outstanding Investment Option specification. Payments of
 principal and interest against a loan shall thereafter be allocated ratably
 among the sub-accounts from which the loan was withdrawn and invested in
 accordance with a Participant’s outstanding Investment Option specification.”
