FOR RELEASE MONDAY SEPTEMBER 8, 1997
- ------------------------------------

        KANSAS CITY, Mo. and COLUMBUS, Ohio - H&R Block Inc. (NYSE:HRB) and 
CompuServe Corporation (NASDQ:CSRV) today announced that they have entered into 
an agreement with WorldCom Inc. (NASDAQ:WCOM) under which WorldCom will acquire 
CompuServe in a stock for stock transaction.  Based on the closing price of 
WorldCom stock on Friday, September 5, the value of the transaction is 
approximately $1.2 billion.  H&R Block owns approximately 80 percent of 
CompuServe.

        The transaction was unanimously approved by the Board of Directors of 
all three companies.

        Frank. L. Salizzoni, president and chief executive officer of H&R Block
and chairman and acting chief executive officer of CompuServe, said: "I am 
delighted we have achieved the goal we have been working toward for the past 
year.  This is a strategic transaction that provides significant value to both 
H&R Block and CompuServe shareholders and places CompuServe's assets in 
excellent hands for the benefit of its networking and online customers.

        "This is the right time, the right price and the right path for future 
growth," he continued.  "Block shareholders will now be well positioned to reap 
the benefits of our ability to focus all of our attention and resources on the 
dynamic growth opportunities in our tax and financial services business.  And 
CompuServe shareholders will receive a stake in one of the fastest growing and 
most well regarded telecommunications companies in the country."

        Under the terms of the agreement, CompuServe shareholders, including H&R
Block, will receive a fixed exchange ratio of .40625 shares of WorldCom stock 
for each share of CompuServe, subject to adjustment as described below.  Based 
on the price of WorldCom's stock at the close of the market on Friday, September
5, the transaction is valued at approximately $12.80 per CompuServe share.

        The fixed exchange rate pricing mechanism will allow CompuServe 
shareholders to share in the benefits of the transaction and any increase in 
WorldCom's stock price between announcement and the close of the transaction.  
In addition, CompuServe shareholders would be provided with certain protections 
in the event of a downturn in the price of WorldCom stock.  If WorldCom's stock 
price drops below $28.54 per share from its current level of $31.50, the fixed 
exchange ratio converts to a fixed price of $12 per share.  If WorldCom stock 
drops below $24 per share, the pricing structure converts to a fixed exchange 
ratio of .50 and CompuServe has the right to terminate the transaction.

        "We see this as an opportunity to enhance our long distance, local 
service and data transmission businesses with strong new capabilities, and 
CompuServe's outstanding network services fits perfectly with our plans," said 
John W. Sidgmore, vice chairman and chief operations officer of WorldCom.  
"Network services will provide a strong complement of our highly successful 
UUNET Internet division, driving future growth opportunities in the fastest 
growing segment of the telecommunications market."

        Upon completion of the transaction, H&R BLock will hold an approximate 3
percent stake in WorldCom and will evaluate various alternatives to convert its 
holdings into cash in a timely manner.  The proceeds will be used to assist 
Block in growing its business through network expansion and the introduction of 
new financial products and services and to fund the company's stock repurchase 
program.

        H&R Block purchased about 250 franchise and competitors' offices as well
as opened approximately 200 new offices in the United States in fiscal 1997. In
addition, Block acquired The Tax Team Limited a tax preparation company with 12
offices in the United Kingdom, and Cashplan Systems Inc., a Canadian financial
services company with 45 offices throughout the country.

        H&R Block made a major entry into financial services with the purchase 
of Option One Mortgage Corporation from Fleet Financial Group in June.  Option 
One is an originator of nonconforming mortgages with more than $1 billion in 
originations last year and a network of 5,000 mortgage brokers nationwide.  Its
operations will complement Block's existing retail mortgage business which was 
tested in four states last tax season.

        H&R Block also plans to move ahead with its program to repurchase up to 
15 million of its shares in the open market.  However, this program will depend 
on the price of the stock, availability of excess cash, the ability to maintain 
financial flexibility, and other investment opportunities available.

        The transaction with WorldCom is subject to a vote of CompuServe's 
shareholders, Hart-Scott-Rodino review, and customary closing conditions.  Block
has agreed with WorldCom to vote its shares of CompuServe in favor of the merger
at the special meeting of CompuServe shareholders to consider the merger.  In 
addition, Block has granted an option to WorldCom to acquire the shares of 
CompuServe owned by Block in certain circumstances. The transaction will be
treated as a sale of CompuServe's assets for tax purposes. It is expected to
close within six months.

structuring and negotiation of the transaction, and Goldman, Sachs & Co. served
