made to the person who supplied the material; and

to the effect that the material or the identity of the person who supplied it, or both, would be held in confidence; or
(c)
the record contains a preliminary, working or other draft of an official of a public body.

the disclosure of the record would reveal evidence of—
(i)
a substantial contravention of, or failure to comply with, the law; or
(ii)
an imminent and serious public safety or environmental risk; and
(b)
the public interest in the disclosure of the record clearly outweighs the harm contemplated in the provision in question.
