This excerpt taken from the EQR 10-Q filed Nov 6, 2008.
AMENDMENT AND TERMINATION
EQR shall have the right to amend the Plan from time to time, subject to Section 10.3 and 10.4, by an instrument in writing which has been executed on its behalf by a duly authorized officer.
The Plan is strictly a voluntary undertaking on the part of the Employers and shall not be deemed to constitute a contract between an Employer and any Eligible Employee (or any other employee) or any Eligible Trustee, a consideration for, or an inducement or condition of employment for, the performance of the services by any Eligible Employee (or other employee) or any Eligible Trustee. EQR reserves the right to terminate the Plan at any time, subject to Section 10.3, by an instrument in writing which has been executed on its behalf by a duly authorized officer. Upon termination, EQR may (a) elect to continue to maintain the Funding Trust to pay benefits hereunder as they become due as if the Plan had not terminated or (b) direct the Funding Trustee to pay promptly to Participants (or their beneficiaries) the vested balance of their Accounts. For purposes of the preceding sentence, in the event clause (b) is implemented, the Account balance of all Participants who are in the employ of an Employer at the time the Funding Trustee is directed to pay such balances shall become fully vested and nonforfeitable. After Participants and their beneficiaries are paid all Plan benefits to which they are entitled, all remaining assets of the Funding Trust attributable to Participants who terminated employment with the Employers prior to termination of the Plan and who were not fully vested in their Accounts under Article 6 at that time shall be returned to the Employers.
No amendment or termination of the Plan shall adversely affect the rights of any Participant with respect to amounts that have been credited to his or her Account prior to the date of such amendment or termination.
No amendment or termination of the Plan shall cause the Plan to violate Code Section 409A.
