Title 14, Chapter 3, Section 845
Any contract or other instrument in writing executed or entered into
between a corporation and any other person is not invalidated as to
the corporation by any lack of authority of the signing officers in
the absence of actual knowledge on the part of the other person that
the signing officers had no authority to execute the contract or
other instrument if it is signed by any two officers in category 1
below or by one officer in category 1 below and one officer in
category 2 below. Categories shall be as follows:
(1) Category 1 shall consist of the presiding officer of the board
and the president; and
(2) Category 2 shall consist of a vice president, the secretary,
the treasurer, and the executive director.
The absence of the signature of such persons from a document shall
not itself impair the validity of the document or of any action
taken in pursuance thereof or in reliance thereon.
