Exhibit 99.1

On December 14, 2005, Critical Path, Inc. (“Critical Path” or “the Registrant”) entered into an Asset Purchase Agreement (the “Agreement”) with Tucows.com Co. (“Tucows” or “the Buyer”) for the sale of a portion of Critical Path’s hosted messaging assets, including a portion of its hosted messaging customer base, assembled hosted messaging workforce and hosted messaging hardware (the “Hosted Assets”). Under the Agreement, Tucows also acquired a software license for Memova™ and agreed to assume certain contractual liabilities related to the Hosted Assets. Tucows paid Critical Path $6.25 million on January 3, 2006, the closing date. Tucows will also pay an additional $1.75 million if certain post-closing conditions related to renewal of services by certain customers through October 31, 2006 are satisfied.

The following unaudited pro forma condensed consolidated balance sheet at September 30, 2005 and the unaudited pro forma condensed consolidated statements of operations data for the nine months ended September 30, 2005 and the year ended December 31, 2004, give pro forma effect to the estimated financial impact of the sale of the Registrant’s Hosted Assets to Tucows. The pro forma condensed consolidated balance sheet at September 30, 2005 gives pro forma effect to the sale of the Hosted Assets as if the transaction was consummated on September 30, 2005. The pro forma condensed consolidated statements of operations data for the nine months ended September 30, 2005 and the year ended December 31, 2004, give pro forma effect to the sale of the Hosted Assets as if the transaction was consummated as of the beginning of the earliest (January 1, 2004) periods presented.

The unaudited pro forma condensed consolidated financial statements are based on the historical consolidated financial statements of Critical Path giving effect to the sale of the Hosted Assets. The adjustments to reflect the sale of Hosted Assets are set forth in the following notes. The Registrant has retained products, operating activities and associated revenues, assets and liabilities, as well as operating expenses, related to its Critical Path’s Memova Messaging, Memova Anti-Abuse, Memova Mobile, Identity Management and Supernews software products and services.

The unaudited pro forma condensed financial data have been prepared by Critical Path’s management for informational purposes only and are not necessarily indicative of how the Critical Path’s balance sheet and operating results would have been presented had the transaction as set forth in the Agreement been consummated on the assumed dates, nor are they necessarily indicative of the presentation of the Critical Path’s balance sheet and statement of operations for any future period.
