2. Whenever a political subdivision is required by any general or
special law to obtain a pledge of assets or other security from a public
depositary for its public deposits and such political subdivision has
entered into a written agreement with such public depositary relating to
such public deposits and has provided written notice in a form specified
by such written agreement to the public depositary of such public
deposits, the public depositary shall comply with the provisions of such
law at the time it accepts any public deposits from the political

political subdivision have agreed in writing as to the maximum amount of
security which such depositary shall provide, and the terms, conditions
and timing of the provisions of security pursuant thereto, and the
depositary has at all times complied with such agreement, it shall be
deemed to have complied with the provisions of such law for so long as
it shall comply with such agreement.
