Mass. Gen. Laws ch. 156D, § 7.30: Voting trusts

Section 7.30. VOTING TRUSTS

(a) One or more shareholders may create a voting trust, conferring on a trustee the right to vote or otherwise act for them, by signing an agreement setting out the provisions of the trust, which may include anything consistent with its purpose, and transferring their shares to the trustee. The trustee shall also sign the voting trust agreement and the shares transferred shall be registered in the name of the trustee. Promptly thereafter, the trustee shall prepare a list of the names and addresses of all owners of beneficial interests in the trust, together with the number and class of shares each transferred to the trust, and deliver copies of the list and agreement to the corporation's principal office.

(b) A voting trust becomes effective on the date the first shares subject to the trust are registered in the trustee's name. A voting trust is valid for the period as is specified in the trust agreement.

(c) All or some of the parties to a voting trust may extend it for additional terms by signing an extension agreement and obtaining the voting trustee's written consent to the extension. An extension is valid for such period as is specified in the extension agreement. The voting trustee shall deliver copies of the extension agreement and list of beneficial owners to the corporation's principal office. An extension agreement binds only those parties signing it.
