Exhibit buildings; matching funds for construction or repair.

In the construction or repair of buildings as authorized by any annual appropriation, the money to be expended therefor from the appropriation shall be matched in an equal amount by the county, municipality, or fair association for which the buildings are to be constructed or repaired. The amount to be paid by the county, municipality, or fair association for the construction or repair shall be made available before the construction or repair is begun. In no event may an amount greater than $25,000 be expended from the appropriation for the construction or repair of exhibit buildings for any one county, municipality, or fair association, from funds appropriated for that purpose; however, any amount not greater than $25,000 may be expended from the appropriation for the construction or repair of exhibit buildings for any one county, municipality, or fair association from the unexpended balance of any appropriation regardless of the amount previously expended under any other legislative appropriation for that one county, municipality, or fair association.
