(2) Is likely to relate solely to the internal personnel rules and practices of the National Science Foundation;

(3) Is likely to disclose matters specifically exempted from disclosure by statute (other than 5 U.S.C. 552): Provided, That the statute (i) requires in such a manner as to leave no discretion on the issue that the matters be withheld from the public, or (ii) establishes particular criteria for withholding or refers to particular types of matters to be withheld;

(4) Is likely to disclose trade secrets and commercial or financial information obtained from a person and privileged or confidential;

(5) Is likely to involve accusing any person of a crime, or formally censuring any person;

(6) Is likely to disclose personal information where the disclosure would constitute a clearly unwarranted invasion of personal privacy;

(8) Is likely to disclose information contained in or related to examination, operating, or condition reports prepared by, on behalf of, or for the use of an agency responsible for the regulation or supervision of financial institutions;

(9) Is likely to disclose information, the premature disclosure of which would:

(ii) Be likely to significantly frustrate implementation of a proposed Foundation action, unless the Foundation has already disclosed to the public the content or nature of its proposed action or is required by law to make such disclosure on its own initiative before taking final action; or

(10) Is likely to specifically concern the Foundation's participation in a civil action or proceeding, an action in a foreign court or international tribunal, or an arbitration.

(b) Anyone who believes his interests may be directly affected by a portion of a meeting may request that the Board close it to the public for any reason referred to in paragraph (a) (5), (6), or (7) of this section. The request should be addressed to the Executive Officer, National Science Board, National Science Foundation, 4201 Wilson Boulevard, Arlington, VA 22230.
