Notes

(1) Based on comparison of historic revenue figures 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- US GAAP financial measures

In addition to reporting financial results in accordance with US GAAP, the Company provides certain non-US GAAP financial measures that are not in accordance with US GAAP. These non-US GAAP financial measures have certain limitations in that they do not have a standardized meaning and thus the Company’s definition may be different from similar non-US GAAP financial measures used by other companies and/or analysts and may differ from period to period. Thus it may be more difficult to compare the Company’s financial performance to that of other companies. However, the Company’s management compensates for these limitations by providing the relevant disclosure of the items excluded in the calculation of adjusted net income and adjusted EPS both in its reconciliation to the US GAAP financial measures of net income and EPS and its consolidated financial statements, all of which should be considered when evaluating the Company’s results. The Company uses the financial measures adjusted EPS and adjusted net income to supplement the information provided in its consolidated financial statements, which are presented in accordance with US GAAP. The presentation of adjusted net income and adjusted EPS is not meant to be a substitute for net income or net income per share presented in accordance with US GAAP, but rather should be evaluated in conjunction with and as a supplement to such US GAAP measures. Open Text strongly encourages investors to review its financial information in its entirety and not to rely on a single financial measure. The Company therefore believes that despite these limitations, it is appropriate to supplement the disclosure of the US GAAP measures with certain non-US GAAP measures for the reasons set forth below. Adjusted net income and adjusted EPS are calculated as net income or net income per share on a diluted basis, excluding, where applicable, the amortization of acquired intangible assets, other income (loss), share-based compensation,, special charges, and the taxation impact of these items. The Company’s management believes that the presentation of adjusted net income and adjusted EPS provides useful information to investors because it excludes non-operational charges. The use of the term “non-operational charge” is defined by the Company as those that do not impact operating decisions taken by the Company’s management and is based upon the way the Company’s management evaluates the performance of the Company’s business for use in the Company’s internal reports. In the course of such evaluation and for the purpose of making operating decisions, the Company’s management excludes certain items from its analysis, such as amortization of acquired intangibles, share- based compensation, special charges, other income/expense and the taxation impact of these items. These items are excluded based upon the manner in which management evaluates the business of the Company and are not excluded in the sense that they may be used under US GAAP. The Company believes the provision of supplemental non-US GAAP measures allows investors to evaluate the operational and financial performance of the Company’s core business using the same evaluation measures that management uses, and is therefore a useful indication of Open Text’s performance or expected performance of recurring operations and facilitates period-to-period comparison of operating performance. As a result, the Company considers it appropriate and reasonable to provide, in addition to US GAAP measures, supplementary non-US GAAP financial measures that exclude certain items from the presentation of its financial results in this press release. The guidance presented is based on (a) financial information prepared by Open Text consistent with the manner in which it reports its revenue, adjusted EPS and net income per share in accordance with GAAP and (b) the assumptions referred to in this note (2). This guidance assumes minimal fluctuations of currency exchange rates.

The following assumptions of Company management are an integral part of the guidance presented for the quarter ending September 30, 2006. Open Text’s actual results for future periods may vary from the guidance presented and such variations may be material.

(a) The guidance assumes a fully diluted weighted average number of shares for the quarter ended September 30, 2006 of approximately 50 million shares.

(b) Income taxes are assumed in the low 30 percent range on an adjusted net income basis.

(c) Assumptions have been made concerning revenue growth and income tax rates that will be in effect; and these rates may change depending upon both the timing and geographical source of future revenues.

(d) The guidance assumes no fluctuation in currency exchange rates.
