(1) Every subscriber of a domestic reciprocal may execute a subscriber’s agreement and power of attorney setting forth the rights, privileges and obligations of the subscriber as an underwriter and as a policyholder, and the powers and duties of the attorney and reciprocal.

(2) If a domestic reciprocal requires execution of a subscriber’s agreement and power of attorney by a subscriber, then the subscriber, by its execution, shall be bound by the terms and conditions of the subscriber’s agreement and power of attorney.

(3) If a domestic reciprocal does not require execution of a subscriber’s agreement and power of attorney, the reciprocal shall include on its policies a statement that the subscriber shall be bound by the terms and conditions of the then current subscriber’s agreement and power of attorney on file with and as approved by the Commissioner of Insurance, and each subscriber shall by operation of law be bound by such subscriber’s agreement and power of attorney as if individually executed by such subscriber. Without additional execution, notice or acceptance, every subscriber of a reciprocal agrees to be bound by any modification of the terms of the subscriber’s agreement and power of attorney which is jointly made by the attorney and the board of directors and amendments thereto, which shall be on file with the attorney and Commissioner of Insurance, which shall become effective upon its approval by the Commissioner of Insurance, and which shall by operation of law bind all subscribers the same as if each subscriber adopted and executed the modified subscriber’s agreement and power of attorney. No such modification shall be effective retroactively, nor shall it affect any insurance contract issued prior to the modification. The Commissioner of Insurance’s approval shall be deemed given if the subscriber’s agreement and power of attorney or any amendment is not disapproved within thirty (30) days of its filing.
