Item 5. Other Events.

            On October 5, 1999, MCI WORLDCOM, Inc. and Sprint Corporation gave a
presentation to analysts regarding the proposed merger (the "Merger") of MCI
WorldCom and Sprint pursuant to an Agreement and Plan of Merger dated as of
October 4, 1999.

            A copy of the presentation to analysts, dated October 5, 1999,
regarding the Merger is attached as Exhibit 99.1 hereto and is incorporated
herein by reference.

            Exhibit 99.1 to this current report on Form 8-K contains
forward-looking statements with respect to the financial conditions, results of
operations and businesses of each of MCI WorldCom and Sprint and, assuming the
completion of the Merger, a combined MCI WorldCom/Sprint, including statements
relating to: (a) the cost savings and accretion to reported earnings that will
be realized from the Merger; (b) the impact on revenues of the Merger; and (c)
the restructuring charges expected to be incurred in connection with the Merger.
These forward looking statements involve certain risks and uncertainties.
Factors that may cause actual results to differ from those contemplated by such
forward-looking statements include, among others, the following possibilities:
(a) expected cost savings from the Merger cannot be fully realized or realized
within this expected time-frame; (b) revenues following the Merger are lower
than expected; (c) competitive pressure among companies in the communications
industry increases significantly; (d) costs or difficulties related to the
integration of the businesses of MCI WorldCom and Sprint are greater than
expected; (e) general economic conditions, either internationally or nationally
or in the states in which the combined company will be doing business, are less
favorable than expected; or (f) legislation or regulatory requirements or
changes adversely affect the business in which the combined company would be
engaged.

            Such forward-looking statements speak only as of the date on which
such statements were made, and MCI WorldCom undertakes no obligation to update
any forward-looking statement to reflect events or circumstances after the date
on which any such statement is made to reflect the occurrence of unanticipated
events.
