                           SEPARATION AGREEMENT AND RELEASE

      This Separation Agreement and Release ("Agreement") is made by and between
CRITICAL PATH, INC. (the "Company"), and LAUREEN DEBUONO ("Consultant")
(collectively referred to herein as the "Parties") as of the date last executed.

      WHEREAS, Consultant was employed by the Company as a full time consultant
with the title of Executive Vice President and Chief Executive Officer pursuant
to that certain Consulting Agreement dated as of August 16, 2001, and as amended
by an Addendum dated as of October 31, 2001 (together, the "Consulting
Agreement"); and

      WHEREAS, the Company and Consultant have each agreed as to Company's
termination of the Consulting Agreement, and this Agreement serves to terminate,
amend and replace such Consulting Agreement in its entirety.

      NOW THEREFORE, in consideration of the mutual promises made herein, the
Company and Consultant hereby agree as follows:

1. Termination. In accordance with Section 9 of the Consulting Agreement,
Company properly notified Consultant with sufficient notice of a termination of
employment on January 15, 2003 ("Effective Date"). Consultant has seven (7) days
following the execution of this Agreement to revoke the Agreement by sending a
written notice to the Company to the attention of General Counsel, Critical
Path, Inc., 350 The Embarcadero, 6th Floor, San Francisco, California
94105-1204. This Agreement shall not be effective until the revocation period
has expired, which shall be the eighth day after it is signed by Consultant,
assuming such Agreement was previously signed by the Company. Notwithstanding
the foregoing, Consultant's employment and provision of services to the Company
shall continue in his or her current position ("Transition Period") through
March 1, 2003, or for a period ending as may be amended between the parties
prior to such date ("Termination Date"). Consultant shall paid regular base
salary on the regular Company payroll schedule and continue to vest in all stock
options (see Section 3 below) on his or her regular vesting schedule and shall
accrue any other applicable employment benefits including Paid Time Off through
the Termination Date. During the Transition Period, Consultant shall provide
services in accordance with the duties and responsibilities of his or her
current position and facilitate an orderly transition of all pending work.

2. Consideration. On the Effective Date (as defined in Section 1) and in
accordance with the terms and conditions of the Consulting Agreement, the
Company agrees to pay Consultant One Hundred and Four Thousand dollars and zero
cents ($104,000.00), which equals two (2) months' fees as salary under with the
Consulting Agreement at the Consultant's current base salary ("Severance
Amount"). In addition, Consultant acknowledges receipt of Company's payment of
One Hundred and Four Thousand dollars and zero cents ($104,000.00) which equals
sixty (60) days' fees as salary at the Consultant's current base salary
("Statutory Payment") in lieu of notice of termination as required pursuant to
applicable federal and state law (together, the Severance Amount and the
Statutory Payment shall constitute the "Separation Amount"). Separation

<PAGE>

Amount payments will be paid less all applicable withholdings, in accordance
with the Company's standard payroll practices and Consultant's applicable tax
designations.

3. Vesting of Stock Options.

      As of the Termination Date, Consultant shall cease vesting in all such
Options previously granted to Consultant. Consultant's right to exercise the
Options shall be governed by the terms and conditions of the applicable Company
Stock Option Plans and Stock Option Agreement(s) between Consultant and the
Company, including periods after termination for the exercise of the Options,
except as expressly modified by this Agreement. Consultant confirms that he or
she has read and understood the terms and conditions of the Stock Option Plan
and his or her Stock Option Agreement and understands his or her
responsibilities contained therein, including the procedures for exercise of
stock options contained therein. Consultant understands that this Agreement
varies the expiration of such Options from that found in the applicable plan and
the right to exercise such Options shall instead expire on March 1, 2004 with no
further extension of such period being granted. Except as otherwise noted
herein, nothing in this Agreement is intended to otherwise supersede or modify
the terms and conditions of the Company's Stock Option Plans or any agreements
issued in connection with those plans. Company shall not be responsible for the
payment of any exercise price or taxes due in connection with the exercise of
such Options.

4. Benefits. Consultant acknowledges that she received no health insurance
benefits in accordance with her Consulting Agreement and therefore is in
eligible for extension of such benefits under the Consolidated Omnibus Budget
Reconciliation Act of 1985 ("COBRA"). Nothing in this Agreement shall otherwise
supersede or modify the terms and conditions of the Company's benefits plans or
the application to Consultant.

5. Payment of Salary. On or before the Termination Date, the Company will pay
all earned but unpaid salary, wages, accrued Paid Time Off, mutually determined
bonuses, commissions and all other benefits due to Consultant up through the
Termination Date. Company will reimburse Consultant for all approved business
related expenses accrued through the Termination Date, to the extent that they
were incurred in accordance with the current Company travel and expense policies
and are properly submitted within ten (10) business days of the Termination
Date.

6. Release of Claims.

      a. Civil Code Section 1542. In connection with all releases effected by
this Agreement ("Release"), Consultant expressly waives any rights or benefits
under Section 1542 of the California Civil Code, or any other equivalent
statute. California Civil Code Section 1542 (or similar state statutes),
provides as follows:

      A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT
      KNOW OR SUSPECT TO EXIST IN HIS [OR HER] FAVOR AT THE TIME OF EXECUTING
      THE RELEASE, WHICH IF

<PAGE>

      KNOWN BY HIM [OR HER] MUST HAVE MATERIALLY AFFECTED HIS [OR HER]
      SETTLEMENT WITH THE DEBTOR.

Consultant fully understands that if any fact, with respect to any matter,
covered by this Release is found hereafter to be other than or different from
the facts now believed by them to be true, they expressly accept and assume that
this Release shall be and remain effective, notwithstanding such difference in
the facts.

      b. Release. Consultant agrees that the Separation Amount represents
adequate consideration for the purpose of this Release and such Separation
Amount constitutes settlement in full of all outstanding obligations owed to
Consultant by the Company, with the exception of payment of base salary and
earned but unpaid benefits through the Termination Date. Except for the promises
or obligations made or undertaken in this Agreement and in exchange for the
payments and other consideration provided hereunder, Consultant, on behalf of
himself or herself, and his or her respective heirs, family members, executors,
and assigns, hereby fully and forever releases, acquits, and discharges the
Company and its respective officers, directors, consultants, investors,
shareholders, administrators, affiliates, divisions, subsidiaries, predecessor
and successor corporations, and assigns, from, and agrees not to sue concerning,
any claim, duty, obligation or cause of action relating to any matters of any
kind, whether presently known or unknown, suspected or unsuspected, that he or
she may possess arising from any omissions, acts or facts that have occurred up
until and including the Effective Date of this Agreement including, without
limitation, any and all claims relating to or arising from Consultant's
employment relationship with the Company and the termination of that
relationship; any and all claims relating to, or arising from, Consultant's
right to purchase, or actual purchase of shares of stock of the Company,

in Employment Act of 1967, the Americans with Disabilities Act of 1990, the Fair
Labor Standards Act, the California Fair Employment and Housing Act, and Labor
Code section 201, et seq., and all as may be amended from time to time; any and
all claims arising out of any other laws and regulations relating to employment
or employment discrimination; and any and all claims for attorneys' fees and
costs.
