Authorizes the President, with respect to certain Defense Production Act activities, to exempt persons participating in a voluntary agreement or plan of action on behalf of the United States from Federal antitrust laws or any similar State law for activities engaged in as part of such agreement or plan. Requires an individual designated by the President to administer such an agreement or plan to provide prior written notice of the time, place, and nature of any meeting to carry out such agreement or plan to the Attorney General, the Chairman of the Federal Trade Commission, and the Congress. Outlines requirements for, and limitations to, the antitrust defense for participants in such agreements or plans. Exempts any activity or provision of such agreements or plans from the Federal Advisory Committee Act and other Federal law relating to advisory committees.

Authorizes the President to order a priority in the allocation of materials, facilities, and services (currently, only materials and facilities) when requirements of national defense cannot otherwise be met. Requires the President to reach certain determinations concerning the critical shortages of such materials, facilities, and services before exercising such authority.

Makes this Act effective (retroactively) on October 20, 1990.

Makes permanent (currently expires upon termination of the Act) a provision of the Defense Production Act of 1950 authorizing the President to review, and if necessary, prohibit foreign mergers, acquisitions, or takeovers in the United States if such actions might adversely affect national security interests.
