CRITICAL PATH, INC.

NOTICE OF WITHDRAWAL

To Critical Path, Inc.:

I previously received a copy of the exchange offer, dated May 31, 2006, and the Election Form. I signed and returned the Election Form, in which I elected to tender some or all of my eligible options. I understand that Critical Path will not accept any conditional or partial returns of individual eligible option grants and that for each eligible option grant previously tendered I must withdraw my election as to the entire eligible option grant. I wish to change that election and withdraw from the offer with respect to the eligible option grants listed below:

[Participant Name and Address] [Participant ID]

Grant Date	Expiration Date		Grant Type		Exercise Price Per Share		Number of Shares Underlying Eligible Options
[                    ]	[	]	[	]	[	]	[	]

I further understand that, by signing this Notice of Withdrawal and delivering it to Critical Path, I withdraw my acceptance of the exchange offer and reject the exchange offer with respect to the eligible option grants listed above. By rejecting the exchange offer with respect to the eligible option grants listed above, I understand that I will not receive any new options in exchange for those eligible option grants and I will retain those option grants with their existing term, exercise price, vesting schedule and other terms and conditions. I agree that Critical Path has made no representations or warranties to me regarding my rejection of the exchange offer. The withdrawal of the eligible option grants listed above is at my own discretion. I agree that Critical Path will not be liable for any costs, taxes, losses or damages I may incur as a result of my decision to withdraw the eligible option grants listed above.

I elect to withdraw the eligible option grants listed above that I previously chose to exchange pursuant to the exchange offer and, therefore, I have completed and signed this Notice of Withdrawal exactly as my name appears on the Election Form that I previously submitted.
