This release contains forward-looking statements, which address a variety of subjects including, for example, the company's future growth prospects. All statements other than statements of historical fact, including without limitation, those with respect to CMGI's goals, plans, expectations and strategies set forth herein are forward-looking statements. The following important factors and uncertainties, among others, could cause actual results to differ materially from those described in these forward-looking statements: CMGI's success, including its ability to improve its cash position, expand its operations and revenues, improve its gross margins and sustain profitability, depends on its ability to execute on its business strategy and the continued and increased demand for and market acceptance of its products and services, including those of its subsidiary, ModusLink; CMGI's management may face strain on managerial and operational resources as they try to oversee the expanded operations; CMGI may not be able to expand its operations in accordance with its business strategy; CMGI's cash balances may not be sufficient to allow CMGI to meet all of its business and investment goals; CMGI may experience difficulties integrating technologies, operations and personnel in accordance with its business strategy; CMGI derives a significant portion of its revenue from a small number of customers and the loss of any of those customers would significantly damage CMGI's financial condition and results of operations; ModusLink frequently sells to its supply chain management clients on a purchase order basis rather than pursuant to long-term contracts or contracts with minimum purchase requirements, and therefore its sales are subject to demand variability; the mergers and acquisitions and IPO markets are inherently unpredictable and liquidity events for companies in the venture capital portfolio may not occur; and increased competition and technological changes in the markets in which CMGI competes. For a detailed discussion of cautionary statements that may affect CMGI's future results of operations and financial results, please refer to CMGI's filings with the Securities and Exchange Commission, including CMGI's most recent Quarterly Report on Form 10-Q. Forward-looking statements represent management's current expectations and are inherently uncertain. We do not undertake any obligation to update forward-looking statements made by us.
