(5) A statement by the affiant in the following language:
The foregoing is principally based on the attached exhibits which, to the best of my knowledge and belief, are complete, true and correct.

(6) As an attachment, records or other available evidence to show:
(i) That the wildlife in question was being held in captivity or in a controlled environment on December 28, 1973;
