If the Participant received a total distribution of his or her partially vested Company Matching Contribution Account within five (5) years of his or her reemployment date, he or she may repay to the Trustee the total amount previously distributed to him or her (including all Accounts) as a result of his or her earlier termination of employment within five (5) years of his or her reemployment date. If a Participant makes such a repayment to the Trustee, both the amount of the repayment and the Forfeiture that resulted from the previous termination of employment shall be credited to his or her Accounts as of the Valuation Date coincident with or next following the date of repayment and he or she shall continue to vest in such amounts.

However, pre-break Forfeitures will not be restored to such Participant’s Accounts and such Participant’s post-break Service shall be disregarded for purposes of vesting in his or her pre-break Company Matching Contribution Account.

(B) Reemployment with No Vested Interest in Plan Accounts. If, at the time the Participant terminated employment, he or she did not have either (i) a vested interest in his or her Company Matching Contribution Account, or (ii) amounts credited to his or her Salary Reduction Contributions Account, the following rules shall apply:

(1) If the Participant is reemployed by a Company Affiliate before he or she incurs five (5) consecutive One-Year Breaks In Service, the amount of the Forfeiture that resulted from his or her previous Termination of Employment shall be credited to his or her Accounts as of the Valuation Date coincident with or next following the date of his or her reemployment or as soon as administratively feasible thereafter and he or she shall continue to vest in such amounts.

(2) If the Participant is reemployed by a Company Affiliate on or after he or she incurs five (5) consecutive One-Year Breaks in Service, pre-break Forfeitures shall not be restored to his or her Accounts. In addition, if the Participant’s number of consecutive One-Year Breaks In Service exceeds the greater of five (5) or the aggregate number of such Participant’s pre-break Service, such pre-break Service shall be disregarded for purposes of vesting in amounts credited to his or her Company Matching Accounts after such reemployment.

(C) Forfeitures. Forfeitures that are credited to a Participant’s Accounts under this Section shall be (i) allocated from amounts forfeited under Section 9.1 or the applicable Appendix, (ii) provided by the Company by way of a separate Plan contribution, or (iii) in the absence of such amounts, shall reduce income and gains of the Fund to be credited under Article 8, in the discretion of the Plan Administrator.

APPENDIX S
MERGER OF THE
YUCCA MOUNTAIN 401(k) SAVINGS PLAN
WITH AND INTO THE PLAN

(Effective September 30, 2014)

1. Effective Date. Effective as of September 30, 2014, (the “Merger Effective Date”), the Yucca Mountain 401(k) Savings Plan (the “Yucca Plan”), a frozen defined contribution plan, shall be merged with and into the Plan. As of the Merger Effective Date, there are no participants in the Yucca Plan who are actively employed by USA Repository Services (the former plan sponsor of the Yucca Plan).

2. General Provisions. As of the Merger Effective Date, the Plan assumed all obligations of the Yucca Plan and became responsible for payment of all account balances under the Yucca Plan for participants, former participants, beneficiaries and alternate payees pursuant to a qualified domestic relations order (as defined in Code Section 414(p)) in the Yucca Plan immediately prior to the Merger Effective Date. As of the Merger Effective Date, such participants, former participants, beneficiaries and alternate payees automatically became Participants in the Plan with respect to such account balances under the Yucca Plan, all of which are 100% vested.

3. Plan Assets. As of the Merger Effective Date, the assets of the Yucca Plan shall become assets of the Plan. The assets of the Yucca Plan shall be transferred to the Trustee of the Trust established pursuant to the Plan as soon as administratively practicable on or after the Merger Effective Date.

4. Participation. Each participant in the Yucca Plan on September 30, 2014 shall become a Participant in the Plan (but not an Eligible Employee) on the Merger Effective Date.

5. Investment of Account Balance. On the Merger Effective Date the account balances transferred from the Yucca Plan to the Plan will be mapped into investment options in the Plan that are reasonably similar to the options in the Yucca Plan in which the Participant’s account was invested immediately prior to the Merger Effective Date. The transferred account balances will be invested in accordance with each Participant’s new investment directive given in accordance with Section 8.3 as soon as administratively practicable following the Merger Effective Date. In the absence of such investment directive, the transferred account balances will continue to be invested in the investment options into which they were mapped on the Merger Effective Date.
