Forward-Looking and Cautionary Statements

The guidance set forth in this press release contains projections of future results that involve a number of trends, risks and uncertainties and are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. The following important factors could cause actual results to differ materially from those projected in such forward-looking statements.

Demand for D&B's products is subject to intense competition, changes in customer preferences and economic conditions which impact customer behavior. The Company's results are also dependent upon its continued ability to:

-- develop new products;

-- reallocate expense to achieve growth through its financial

flexibility program;

as it implements its financial flexibility program; and

or its data centers.

The Company is also subject to the effects of foreign economies, exchange rate fluctuations and U.S. and foreign legislative or regulatory requirements. Its results are also dependent upon the availability of data from its database. Developments in any of these areas could cause results to differ materially from results that have been or may be projected.

In addition, the Company's projection for operating cash flow in 2003 is dependant upon, among other things, the Company's ability to generate sales, the Company's collection processes, customer payment patterns and the amount and timing of payments related to tax matters and legal proceedings involving the Company as more fully described in the Company's filings with the SEC.
