</TABLE>

Pro-Forma Operating Income/Loss is defined as Operating Income/Loss
excluding in-process research & development expenses, depreciation,
amortization, long-lived asset impairment and restructuring charges.

Actual business performance will be based on the annual achievement of
the defined financial objectives against the FY 2003 Plan, as approved
by the CMGI Board of Directors. CMGI reserves the right to modify the
budget and financial objectives as necessary based on business changes
associated with mergers, acquisitions, divestitures, shutdowns or other
business situations which require approval from the CMGI Board of
Directors. CMGI also reserves the right to adjust the budget based on
changes in corporate allocations.

Program Funding:
The bonus payout pool will be determined by CMGI consolidated business
performance. Exact funding for the bonus pool for CMGI Corporate will
be driven by the ability of CMGI to meet or exceed its budgeted
financial objectives as approved by CMGI's Board of Directors.

Overall business performance generally has a direct correlation to
individual performance. However, the bonus plan provides for discretion
in recognizing individual accomplishments against goals and objectives,
in addition to business performance. All employees enrolled in the FY
2003 Bonus Plan must have clearly documented goals and objectives in
order to be eligible for the Individual Performance measurement. Any
bonus payments for individual performance will be based on
accomplishments against documented individual goals & objectives,
management discretion and overall bonus pool funding.

         Payout Table:
         The table below will be used to determine the bonus pool based on final
         CMGI consolidated business performance. A minimum performance threshold
         of 80% must be achieved for pool funding associated with each specific
         financial objective. The maximum pool funding based on business
         performance is 200%. Every 1% increase or decrease in performance
         equals 2.5% increase or decrease in funding.

         Timing of Payment:
         Any earned bonus payments will be measured on an annual basis and paid
         annually. Payments will be determined after all companies have
         submitted their actual performance against FY 2003 Plan.

         Employment Status:
         In order to be eligible to receive any bonus payment under this Plan,
         participants must be actively employed by CMGI at the time annual bonus
         payments are made, which will be as soon as administratively possible
         following the close of the fiscal year. If a participant is a new hire
         during the year or had a bonus change during the year, he or she will
         be eligible for a pro-rated bonus payment based on time worked during
         the plan year. If a participant voluntarily leaves CMGI prior to the
         time the bonus payments are made, he/she will be ineligible to receive
         any bonus payment. If an employee is involuntarily terminated by CMGI,
         for reasons other than cause, prior to the time the bonus payments are
         made, he/she may, in certain circumstances, be eligible for
         consideration for a pro-rated bonus payment based on management
         discretion and time worked during the plan year. If a participant
         transfers to any other CMGI controlled subsidiary, he/she will be
         eligible for a pro-rated bonus payment based on management discretion
         and for the time worked during the plan year.

         Administration:
         This plan shall be administered by the CMGI Board of Directors. The
         CMGI Board of Directors reserves the right to apply its discretion to
         bonus plan eligibility, overall bonus funding and payment of bonuses.
         The CMGI Board of Directors reserves the right to amend or terminate
         this plan at any time. The CMGI Board of Directors reserves the right
         to modify the financial objectives and FY 2003 Plan at any time based
         on business changes during the year. This plan shall be governed by and
         construed in accordance with the laws of the Commonwealth of
         Massachusetts.
