OPEN TEXT REPORTS STRONG THIRD QUARTER RESULTS

Revenue Grows 82%, Exceeds Earnings Expectations, IXOS Transaction Accretive

WATERLOO, ON—May 5, 2004—Open Text^™ Corporation (Nasdaq: OTEX; TSX: OTC), the world’s largest provider of enterprise content management (ECM) software, today announced financial results for its third quarter ended March 31, 2004.

Financial Highlights

Total revenue for the third quarter was $80.2 million, up 82% from the same period last year and license revenue of $34.5 million grew by 82% over the prior year. (1)

Open Text reported an 81% increase in total adjusted net income for the third quarter of $12.2 million, or adjusted earnings per share (EPS) of $0.25. This compares to adjusted net income of $6.7 million, or $0.16 adjusted EPS in the third quarter a year ago, marking the 21st consecutive profitable quarter for the Company. (2)

Open Text reported total net income for the third quarter in accordance with U.S. generally accepted accounting principles (GAAP) of $3.3 million, or $0.07 EPS, compared to net income of $6.8 million, or $0.16 EPS in the third quarter a year ago. In the quarter the Company incurred an after tax restructuring charge of $7.5 million.

“We are pleased to have achieved strong profit results in the quarter,” said Tom Jenkins, CEO of Open Text. “The addition of IXOS has been immediately accretive to our results and enhanced our pipeline by significantly expanding our global customer base. As the world’s largest ECM vendor, our leadership position is driven by continued customer demand for our software.” (3)

Total cash flow from operations in the quarter was a record $15.4 million, an increase of 45% over the prior year. The total cash on hand at quarter end was $153.3 million or $3.21 per share (fully diluted).

At quarter end, total deferred revenue was $68.0 million, up $30.9 million or 83% over a year ago.

Revenue results were broadly based, with 45% derived from North America, 48% from Europe and 7% from the Middle East and Asia.

Open Text owns approximately 88% of IXOS Software AG. As of March 1, 2004, Open Text began including the results of IXOS in its financial statements on a consolidated basis, and these results include one month’s revenue and expense.

“We are very pleased that the IXOS integration is proceeding according to plan, as evidenced by the recent product roadmap we publicly presented last week to over 1500 attendees at our LinkUp Europe user conference,” said John Shackleton, President of Open Text.

Guidance

See accompanying Notes (2) (4) (5) and (6)

The Company is maintaining its previously announced guidance for the remainder of Fiscal Year 2004 and for Fiscal Year 2005.

Notes

(1) All dollar amounts in this press release are in US Dollars unless otherwise indicated.

(2) The Company uses the financial measure adjusted EPS and adjusted net income to supplement its consolidated financial statements, which are presented in accordance with 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 is calculated as net income (or per share, as applicable), excluding the following estimated amounts (a) the amortization of acquired intangible assets (FY04 Q4 - $4.0 million, FY05 - $16.0 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 (FY04 Q4 - nil, FY05 - nil). All the aforementioned amounts are provided net of tax. 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.

(3) Based on comparison of future annual revenue guidance publicly disseminated by companies in the Enterprise Content Management (“ECM”) sector.

(4) 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 notes (2) and (5). This guidance assumes minimal fluctuations of currency exchange rates.

(5) The following assumptions of Company management are an integral part of the guidance presented for the balance of FY04 and FY05. These assumptions represent the current expectations of Open Text but must be considered preliminary as they will be reviewed and revised, perhaps materially, based upon Open Text’s assessment of the operations of IXOS and discussions with IXOS following completion of the offer to acquire all outstanding shares of IXOS and completion of other agreements between IXOS and Open Text as described in the offer document. 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 share count for the quarter ending June 30, 2004, of 55 million shares, and for the fiscal year ending June 30, 2005, of 56.0 million shares. (b) Guidance for adjusted EPS and net income per share is calculated on a fully-diluted basis, giving effect to the exercise of the common share purchase warrants issued under the Offer. (c) Income taxes are assumed at a rate of 30 to 35% on a GAAP net income basis. (d) Assumptions have been made concerning revenue growth and income tax rates that will be in effect and which may change depending upon both the timing and jurisdiction of future revenues.

- 4 -

(6) The Company has provided a reconciliation in note (2) above of its guidance for adjusted EPS to net income per share, which is the most comparable financial measure calculated and presented in accordance with GAAP. With respect to amortization of acquired intangible assets, the Company has retained the services of an independent valuator to assist in the valuation of intangible assets acquired through the business combination with IXOS. The Company estimates that the additional amortization will be approximately $2.5 million per quarter (net of tax) for the next 5 to 7 years and is based on previous experience with similar transactions. The specific amount of this amortization expense for future periods will be determined once this valuation work is completed.
