         BASKING RIDGE, N.J. - Avaya Inc. (NYSE:AV), a leading global provider
of voice and data networks, today said it expects revenues for its second fiscal
quarter ending March 31, to be approximately $1.240 billion to $1.275 billion,

for the second fiscal quarter to be a loss of six cents to 10 cents per diluted
share, compared with a loss of eight cents, as previously stated.

         Avaya announced a plan designed to enhance its liquidity, strengthen
its balance sheet and simplify its capital structure. The plan includes the
following steps:

         o        The sale of 14,383,953 shares of common stock to Warburg
                  Pincus Equity Partners at a price of $6.26 per share, the
                  closing price of Avaya's common stock on Friday March 8, 2002.

         o        The conversion of approximately $438 million of Avaya
                  preferred stock held by Warburg Pincus Equity Partners into
                  38,329,365 shares of Avaya common stock and the exercise by
                  Warburg Pincus Equity Partners of warrants to purchase
                  approximately another 286,000 shares of Avaya common stock.

         As a result of the stock transactions, Warburg Pincus Equity Partners
will own about 53 million shares of Avaya common stock or approximately 15.5
percent of the total outstanding.

         Jeffrey Harris, Senior Managing Director of Warburg Pincus LLC,
resigned from Avaya's board prior to the board's approval of the transaction.
Warburg Pincus will retain its right to nominate an unaffiliated director to
Avaya's board.

         The agreements with Warburg Pincus Equity Partners are contingent on
receiving Hart-Scott-Rodino anti-trust clearance and other customary conditions.

         Avaya also announced it may seek to offer $100 million in common equity
(plus an over allotment option of up to 15 percent) and is evaluating capital
market alternatives to repay its existing bank debt and replace it with
longer-term debt.

         Bear Stearns acted as financial advisor to Avaya in connection with the
Warburg transactions.

AS REPORTED RESULTS

         On an as reported basis, the company expects a net loss of between 68
cents and 72 cents per diluted share, including the impact of a restructuring
charge of approximately $100 million and a one-time retained earnings charge of
approximately $130 million associated with the conversion of preferred stock and
warrants owned by Warburg Pincus Equity Partners.

         The company said the restructuring charge, which it expects to take in
the second fiscal quarter, reflects actions it has taken to date this quarter.

million to $200 million. As part of the restructuring, about 1900 positions are
being eliminated.
