The Township shall have the right at any time to amend the Plan. However, no such amendment shall authorize or permit any part of the Trust Fund (other than such part as is required to pay taxes and administration expenses) to be used for or diverted to purposes other than for the exclusive benefit of the Participants or their Beneficiaries or estates; no such amendment shall cause or permit any portion of the Trust Fund to revert to or become the property of the Township; and no such amendment which affects the rights, duties or responsibilities of the Trustee and the Administrator may be made without the Trustee's and Administrator's written consent. Any such amendment shall become effective as provided therein upon its execution. The Trustee shall not be required to execute any such amendment unless the Trust provisions contained herein are a part of this agreement and the amendment affects the duties of the Trustee hereunder.
