Webster defines the word ``unify'' to mean ``to cause to be one; to
make into a unit; to unite.'' The pertinent definition of ``operation''
is a method or way of operating, working or functioning. Since the term
``unified operation'' has reference to the method of performing the
related activities, it means combining, uniting, or organizing their
performance so that they are in effect a single business unit or an
organized business system which is an economic unit directed to the
accomplishment of a common business purpose. The term ``unified
operation'' thus includes a business which may consist of separate
segments but which is conducted or operated as a unit or as a single
business for a common business purpose.
