In addition to generally accepted types of security, the endorsement of a note by a surety, comaker or guarantor, or assignment of shares or wages, in a manner consistent with the laws of this State, shall be deemed security within the meaning of this Act. A credit union shall give each surety, guarantor or comaker a copy of the instrument evidencing the indebtedness. The adequacy of any security shall be determined by the credit committee , credit manager or loan officer, subject to this Act and the bylaws of the credit union. The surety, guarantor or comaker may, but need not, be a member of the credit union making the loan.
