Notes

(1) Based on comparison of future annual revenue guidance publicly disseminated by companies in the Enterprise Content Management (“ECM”) sector. All dollar amounts in this press release are in US Dollars unless otherwise indicated.

(2) Use of Non-GAAP financial measures

The non-GAAP financial measures used in this press release are not prepared in accordance with US GAAP and may be different from non-GAAP financial measures used by other companies. The Company uses the financial measure adjusted EPS and adjusted net income to supplement its consolidated financial statements, which are presented in accordance with US GAAP. The presentation of adjusted EPS and adjusted net income is not meant to be a substitute for net income per share presented in accordance with GAAP, but rather should be evaluated in conjunction with such GAAP measure. Adjusted EPS and adjusted net income are calculated as net income (or per share on a fully diluted basis, as applicable), excluding the following estimated amounts (a) the amortization of acquired intangible assets (Q2FY05—$4.6 million), (b) other income, gain (loss) on investments (nil), (c) income tax on equity gain (nil), and (d) restructuring charges including charges that will be incurred as a result of the acquisition of IXOS (nil). All of the aforementioned amounts are provided net of tax and extraordinary gains or losses. The term adjusted EPS and adjusted net income does not have a standardized meaning prescribed by GAAP, and therefore the Company’s definition is unlikely to be comparable to similar measures presented by other companies. The Company’s management believes that the presentation of adjusted EPS and adjusted net income provides useful information to investors because it excludes non-operational charges and is a better indication of Open Text’s profitability or expected profitability from recurring operations. The items excluded from the computation of adjusted EPS and adjusted net income, which are otherwise included in the determination of net income per share prepared in accordance with GAAP, are items that Open Text does not consider to be meaningful in evaluating the Company’s past financial performance or future prospects and may hinder a comparison of its period-to-period profitability.

The following chart provides reconciliation (unaudited) of GAAP based EPS to non-GAAP EPS estimates for the three months ended December 31, 2004. EPS has been calculated on a fully diluted basis.
