Except as provided for in this article, the Regents of the University of California shall let all contracts involving an expenditure of more than one hundred thousand dollars ($100,000) annually for goods and materials to be sold to the University of California to the lowest responsible bidder meeting specifications, or else reject all bids. Contracts for services to be performed, other than personal or professional services, involving an expenditure of one hundred thousand dollars ($100,000) or more annually shall be made or entered into with the lowest responsible bidder meeting specifications, or else all bids shall be rejected. If the regents deem it to be for the best interest of the university, the regents may, on the refusal or failure of the successful bidder for materials, goods, or services to execute a tendered contract, award it to the second lowest responsible bidder meeting specifications. If the second lowest responsible bidder fails or refuses to execute the contract, the regents may likewise award it to the third lowest responsible bidder meeting specifications.
