If the members of a municipal electric energy cooperative and the legislative bodies of the municipalities are not paying compensation to the representatives they each appointed pursuant to subsection (a) of § 7-233c, such municipal electric energy cooperative may reimburse its representatives for necessary expenses incurred in the discharge of their duties and pay such reasonable, uniformly applicable compensation to such representatives for their service on the board of such municipal electric energy cooperative as provided in this section. The concurrent resolutions creating a municipal electric energy cooperative may provide that the representatives of the municipal electric energy cooperative may receive annual compensation for their services within limitations to be stated in such concurrent resolutions and in that event, each representative may receive from the municipal electric energy cooperative such compensation for his services as the municipal electric energy cooperative may determine within the limitations stated in such concurrent resolutions. Said provisions or limitations stated in any such resolutions may be amended by subsequent concurrent resolutions, but no reduction of any such limitation shall be effective as to any representative of the municipal electric energy cooperative then in office except upon the written consent of such representative.
