Any governmental member of the commission may terminate its membership after giving not less than ninety days' notice in writing of its intention to withdraw. The notice shall be served upon the chairman of the commission personally or by mail. The ninety-day period begins to run from the date the notice is received by the chairman. The withdrawal of a member does not abrogate or impair any contract or commitment previously made by the withdrawing governmental agency for the fiscal year.
