2 Forward-Looking Statements The following information includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements regarding Knoll, Inc.'s expected future financial position, results of operations, revenue and profit levels, cash flows, business strategy, budgets, projected costs, capital expenditures, products, competitive positions, growth opportunities, plans and objectives of management for future operations, as well as statements that include words such as "anticipate," "if," "believe," "plan,"  "goals, " "estimate," "expect," "intend," "may," "could," "should," "will," and other similar expressions are forward-looking statements. This includes, without limitation, our statements and expectations regarding any current or future recovery in our industry and our publicly announced plans for increased capital and investment spending to achieve our long-term revenue and profitability growth goals.  Such forward-looking statements are inherently uncertain, and readers must recognize that actual results may differ materially from the expectations of Knoll management. Knoll does not undertake a duty to update such forward-looking statements. Factors that may cause actual results to differ materially from those in the forward-looking statements include corporate spending and service-sector employment, price competition, acceptance of Knoll's new products, the pricing and availability of raw materials and components, foreign currency exchange, transportation costs, demand for high quality, well designed office furniture solutions, changes in the competitive marketplace, changes in the trends in the market for office furniture or coverings, the financial strength and stability of our suppliers, customers and dealers, access to capital, and other risks identified in Knoll's annual report on Form 10-K, and other filings with the Securities and Exchange Commission. Many of these factors are outside of Knoll's control.
