4.The pooling agreement is generally recognized as a valid contract,subject only to the rules applicable to the validity of contracts in general.A few states have adopted statutes regulating pooling agreements,often limiting the period during which a pooling agreement may continue,requiring that copies of the pooling agreement be deposited at the principal office of the corporation,and so forth.However,in most states,the pooling agreement is essentially an unregulated contractual voting device that may continue for long period of time.
