The contracts of the corporation shall be executed in the name of the corporation by the president of the corporation and attested by the secretary of the corporation. Except for bonds, it is not required that the seal be impressed or printed on contracts. It is further provided hereby that, except for bonds, the corporation may provide by resolution for a different form for the execution of contracts and for the execution thereof by an officer or agent other than the president and secretary. But in no event shall a contract, irrespective of the form and of the person executing the same, be binding unless such contract was authorized or ratified by the corporation.(Act 82-312, p. 420, §7.)
