A secured party has control of electronic chattel paper if the record or records comprising the chattel paper are created, stored, and assigned in such a manner that:
(1) a single authoritative copy of the record or records exists
which is unique, identifiable and, except as otherwise
provided in paragraphs (4), (5), and (6), unalterable;
(2) the authoritative copy identifies the secured party as the
assignee of the record or records;
(3) the authoritative copy is communicated to and maintained by
the secured party or its designated custodian;
(4) copies or revisions that add or change an identified assignee
of the authoritative copy can be made only with the
participation of the secured party;
(5) each copy of the authoritative copy and any copy of a copy is
readily identifiable as a copy that is not the authoritative
copy; and
(6) any revision of the authoritative copy is readily
identifiable as an authorized or unauthorized revision.
