All apparently eligible offerors must be afforded the opportunity to submit best and final proposals if negotiations with any other offeror results in material alteration or reduction in the scope of work or services to the invitation for proposals, and such alteration or reduced scope of work or services has a cost consequence that may alter the order of offerors’ price quotations contained in the initial proposal. In conducting negotiations, there must be no disclosure of any information derived from proposals submitted by competing offerors.
