Cal. Pub. Contract Code § 12101.2
The Department of General Services shall prenegotiate the repetitively used terms and conditions in the state's model contract with each interested vendor who bids or proposes on electronic data processing or telecommunications procurements. The contract language shall be kept on file, as a matter of public record, and shall remain operational until either the state or the vendor provides 30 days' notice to the other party that new negotiations are deemed appropriate.
If, for a particular procurement, the state seeks to make any further changes to either the negotiated or the standard contract language, or both, it shall identify those changes to each bidder or proposer prior to the due date for the bid or proposal. If for a particular procurement, a bidder or proposer seeks to propose a negotiated change or standard contract language change, it shall make this identification within the timeframe identified in the solicitation document.
