WorldCom Announces Redemption Of Series A Convertible Preferred Stock And Related Depositary Shares

Jackson, Miss., May 15, 1998

-- WorldCom, Inc. (Nasdaq: WCOM, WCOMP) today announced that it
has elected to redeem on May 31, 1998 ("Redemption
Date"), all outstanding shares of its Series A 8% Cumulative
Convertible Preferred Stock (the "Series A Preferred
Stock") and related Depositary Shares. Each Depositary Share
represents 1/100 of a share of Series A Preferred Stock. On May 14,
1998, there were outstanding approximately 94,992 shares of Series
A Preferred Stock and 9,499,200 Depositary Shares.

On the Redemption Date, each Depositary Share
will be redeemed for 0.79511 shares of WorldCom Common Stock. The
Company will pay cash in lieu of any fractional share of WorldCom
Common Stock. The right of holders of Series A Preferred Stock and
Depositary Shares to convert, at their option, all or a portion of
such shares into shares of WorldCom Common Stock (at the rate of
3.44274 shares of WorldCom Common Stock for each Receipt evidencing
one Depositary Share) will terminate at 5:00 p.m., New York City
time, on the Redemption Date. In order to accommodate conversions
on the Redemption Date, the Receive and Deliver Window of the
Reorganization & Redemption Department of The Bank of New York,
as the Redemption and Conversion Agent, will be open from 9:00 a.m.
to 5:00 p.m., New York City time, on the Redemption Date, but any
holder tendering Depositary Shares for conversion must do so by
hand or courier delivery, as The Bank of New York will otherwise be
closed

on that date

.

From and after the Redemption Date, (i)
dividends on the Series A Preferred Stock and the Depositary Shares
will cease to accrue, (ii) the Series A Preferred Stock and the
Depositary Shares will no longer be deemed to be outstanding, and
(iii) all rights of the holders of Receipts evidencing Depositary
Shares will cease (except the rights to receive the shares of
Common Stock and cash in lieu of any fractional shares thereof
payable upon such redemption, without interest thereon, upon
surrender of Receipts evidencing Depositary Shares).

The Call Price per share of Series A Preferred
Stock and the Current Market Price per share of Common Stock used
for purposes of determining the exchange rate were $3,417.00 and
$42.975, respectively. The Current Market Price is the lesser of
(i) the average of the high and low sales prices of the Common
Stock as reported on The Nasdaq National Market for the 10
consecutive trading days ending on and including the date of
determination, which was May 14, 1998, or (ii) the closing sale
price regular way of the Common Stock on The Nasdaq National Market
on the date of determination. In accordance with the terms of the
WorldCom Articles of Incorporation, the number of shares of Common
Stock to be exchanged by the Company for each share of outstanding
share of Series A Preferred Stock is the result of dividing the
Call Price by the Current Market Price.

Since the Redemption Date occurs after the May
22, 1998 record date for the quarterly dividend payable on June 1,
1998, the Call Price will not include any accrued or unpaid
dividends.

As a result of the redemption, up to 7,552,942
shares of Common Stock will be issued. If all holders were to elect
to convert their shares, a total of 32,703,276 shares of Common
Stock would be issued. The Company currently has approximately
1,032,087,418 shares of Common Stock outstanding.

The Company is sending a notice of redemption to
the registered holders of the Series A Preferred Stock and the
Depositary Shares, including a Letter of Transmittal to be used in
surrendering certificates and Receipts for redemption or
conversion. Holders of Receipts evidencing Depositary Shares will
be entitled to receive Common Stock (and cash in lieu of any
fractional share thereof) upon redemption on the Redemption Date,
and should surrender their Receipts (together with a properly
completed and executed Letter of Transmittal) to The Bank of New
York, as Depositary and Redemption Agent, at the following
