In addition to joint purchases authorized by section 2308 (relating to bids for certain joint purchases), local governments may make direct purchases from vendors or suppliers of goods, materials or equipment without compliance with existing and otherwise applicable statutory requirements governing competitive bidding and execution of contracts as follows:
(1) Any county may by appropriate resolution, and subject to such reasonable regulations as it may prescribe, permit any local government within the county to participate in or purchase off contracts for goods, materials or equipment entered into by the county.
(2) Any local government desiring to participate in purchase contracts shall file with the county purchasing agency and with the county solicitor a certified copy of an ordinance or resolution of its governing body requesting that it be authorized to participate in purchase contracts of the county and agreeing that it will be bound by the terms and conditions as the county prescribes and that it will be responsible for payment directly to the vendor under each purchase contract.
(3) The county may permit participation by local governments only where the solicitation for bids and specifications for the county contracts, and the contracts themselves, expressly provide for and inform prospective and successful bidders that the contract to be let is intended to be subject to this subchapter and to regulations adopted by the county.
(4) Among the terms and conditions as the county may specify, it shall prescribe that all prices shall be F.O.B. destination.
