(f) If the Participant’s or former Participant’s surviving Spouse is not the Participant’s or former Participant’s sole Section 401(a)(9) Beneficiary and the payment of Plan death benefits to the Section 401(a)(9) Beneficiary will not be in the form of a single sum, then distributions to the Section 401(a)(9) Beneficiary will begin by December

31 of the calendar year immediately following the calendar year in which the Participant or former Participant died.

(h) If there is no Section 401(a)(9) Beneficiary as of September 30 of the calendar year following the calendar year of the Participant’s or former Participant’s death, then the Participant’s or former Participant’s entire Nonforfeitable Interest in his Plan benefit will be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s or former Participant’s death.

(i) If the Participant’s or former Participant’s surviving Spouse is the Participant’s or former Participant’s sole Section 401(a)(9) Beneficiary and the surviving Spouse dies after the Participant or former Participant but before distributions to the surviving Spouse begin, this Section 5.08(e), other than Section 5.08(e)(1), will apply as if the surviving Spouse were the Participant.

If a Participant or former Participant dies on or after his Required Beginning Date, his Plan benefit must be distributed to his Section 401(a)(9) Beneficiary at least as rapidly as the method of payment of minimum required distributions being used as of the date of his death.

(l) Limitations on Death Benefits. Benefits payable under the Plan shall not be provided in any form that would cause a Participant’s or former Participant’s death benefit to be more than incidental. Any distribution required to satisfy the incidental benefit requirement shall be considered a required distribution for purposes of section 401(a)(9) of the Code.

(m) Compliance with Section 401(a)(9). All distributions under the Plan will be made in accordance with the requirements of section 401(a)(9) of the Code and all Regulations promulgated thereunder,

ARTICLE VII

LOANS

(a) Except as specified below, the Committee may direct the Trustees to make loans to Participants (and Beneficiaries who are “parties in interest” within the meaning of ERISA) who have Nonforfeitable Interests in their Account balances. The Committee will be responsible for administering the Plan loan program. All loans will comply with the following requirements:

(b) All loans will be made solely from the Participant’s or Beneficiary’s Account.

(c) Loans will be available on a nondiscriminatory basis to all Beneficiaries who are “parties in interest” within the meaning of ERISA, and to all Participants.

(d) Loans will not be made for less than $1,000.00.

(e) The maximum amount of a loan may not exceed the lesser of (A)

$50,000.00 reduced by the person’s highest outstanding loan balance from the Plan during the preceding one-year period, or (B) one-half of the person’s Nonforfeitable Interest in his Account balance under the Plan determined as of the date on which the loan is approved by the Committee.

(f) Any loan from the Plan will be evidenced by a note or notes (signed by the person applying for the loan in accordance with procedures established by the Committee) having such maturity, bearing such rate of interest, and containing such other terms as the Committee will require by uniform and nondiscriminatory rules consistent with this Article and proper lending practices.

(g) All loans will bear a reasonable rate of interest which will be established by the Committee. In determining the proper rate of interest to be charged, at the time any loan is made or renewed, the Committee will contact at least two of the largest banks in the geographic location in which the Participant or Beneficiary resides to determine what interest rate the banks would charge for a similar loan taking into account the collateral offered.

(h) Each loan will be fully secured by a pledge of the borrowing person’s Nonforfeitable Interest in his Account balance. No more than 50 percent of the person’s Nonforfeitable Interest in his Account balance (determined immediately after the origination of the loan) will be considered as security for any loan.

(i) The term of the loan will not be less than 18 months. Generally, the term of the loan will not be more than five years. The Committee may agree to a longer term (but not more than seven years) only if such term is otherwise reasonable and the proceeds of the loan are to be used to acquire a dwelling which will be used within a reasonable time (determined at the time the loan is made) as the principal residence of the borrowing person.

(j) The terms of each Plan loan agreement will require substantially level amortization of the loan (with payments not less frequently than quarterly) over the term of the loan. However, the level amortization requirement will not apply for a period, not longer than one year (or such longer period as may apply under the Uniformed Services Employment and Reemployment Rights Act of 1994) that an eligible borrower is on a bona fide leave of absence, either without pay from the District or at a rate of pay (after income and employment tax withholding) that is less than the amount of the installment payments required under the terms of the loan. However, the loan (including interest that accrues during the leave of absence) must be repaid by the five-year loan maturity deadline specified in paragraph (h) above (unless the loan was a home loan described in paragraph (h) above), and the amount of the installments due after the leave ends (or, if earlier, after the first anniversary of the leave or such longer period as may apply under the Uniformed Services Employment and Reemployment Rights Act of 1994) must not be less than the amount required under the terms of the original loan.

(k) Except with respect to a former Employee as provided in subsection (l) herein, a Participant’s loan agreement will require that loan repayments be made through payroll deductions.

(l) If a person fails to make a required payment within 30 days of the due date set forth in the loan agreement, the loan will be in default.

(m) If a Participant or former Participant has an outstanding loan from the Plan at the time of his Separation From Service, the Participant or former Participant will have the right to elect to continue to repay the loan in accordance with its terms; provided that if such an election is made such election shall be irrevocable and the Participant shall not be eligible to receive a distribution from the Plan until he has fully repaid the loan. If the Participant or former Participant does not elect to continue to repay the loan in accordance with its terms, the outstanding loan principal balance and any accrued but unpaid interest will become immediately due in full. The Participant or former Participant will have the right to immediately pay the Trustee that amount. If the Participant or former Participant fails to repay the loan, the Trustee will foreclose on the loan and the Participant will be deemed to have received a Plan distribution of the amount foreclosed upon. The Trustee will not foreclose upon a Participant’s or former Participant’s Salary Deferral Contribution Account or Catch-up Salary Deferral Contributions Account until the Participant’s Separation From Service.

(n) If a Beneficiary defaults on his loan, the Trustee will foreclose on the loan and the Beneficiary will be deemed to have received a Plan distribution of the amount foreclosed upon.

(o) No amount that is pledged as collateral for a Plan loan to a Participant will be available for withdrawal before he has fully repaid his loan.

(p) All interest payments made pursuant to the terms of the loan agreement will be credited to the borrowing person’s Account and will not be considered as general earnings of the Trust Fund to be allocated to other Participants.

26. The first paragraph of Article VIII shall be amended and restated in its entirety to provide as follows:

A Participant or former Participant has a fully Nonforfeitable Interest in his entire Account balance when he (a) incurs a Disability on or prior to the date of his Separation From Service, (b) attains his Normal Retirement Age on or prior to the date of his Separation From Service, or (c) incurs a Separation From Service due to death.
