(a) Making of Additional Copy or Adaptation by Owner of Copy. -
Notwithstanding the provisions of section 106, it is not an infringement for
the owner of a copy of a computer program to make or authorize the making of
another copy or adaptation of that computer program provided:
(1) that such a new copy or adaptation is created as an essential step in
the utilization of the computer program in conjunction with a machine and
that it is used in no other manner, or
(2) that such new copy or adaptation is for archival purposes only and that
all archival copies are destroyed in the event that continued possession of
the computer program should cease to be rightful.
