                  CRITICAL PATH ADOPTS SHAREHOLDER RIGHTS PLAN

     San Francisco, CA., (March 30, 2001) -- Critical Path, Inc. (NASDAQ: CPTH)
announced today that its Board of Directors has adopted a Shareholder Rights
Plan. Under the plan, Rights will be distributed as a dividend at the rate of
one Right for each share of the company's common stock held by shareholders of
record as of the close of business on May 15, 2001.

     The Rights Plan is designed to prevent an acquirer from gaining control of
Critical Path without offering a fair and adequate price and terms to all of
Critical Path's shareholders. The Rights Plan is intended to increase Critical
Path's ability to negotiate with potential acquiring companies to maximize
shareholder value and is not intended to interfere with takeover offers or other
strategic alternatives that the company's Board of Directors believes are in the
shareholders' best interests. The Rights Plan was not adopted in response to any
attempt to acquire the company.

     Under the plan, each Right will entitle shareholders to purchase a
fractional share of the company's preferred stock for $25.00. Initially, the
Rights will not be exercisable and will trade with Critical Path's common stock.
Generally, the Rights may become exercisable if a person or group acquires
beneficial ownership of 15 percent or more of Critical Path's common stock or
commences a tender or exchange offer upon consummation of which such person or
group would beneficially own 15 percent or more of Critical Path's common stock.

     Further details of the Rights Plan are outlined in a letter that will be
mailed to shareholders as of the record date. Additionally, a copy of the Rights
Plan will be filed shortly with the Securities and Exchange Commission.
