Dear Christian:

It is a distinct pleasure to offer you the position of President and Chief
Executive Officer of uBid, Inc. ("uBid"). In this capacity you will report to
the Board of Directors of uBid.

Your starting salary will be $13,461.53 bi-weekly, which is equivalent to an
annualized base salary of $350,000.00. You will also be eligible to receive a
pro-rated bonus for fiscal year 2002, ending 7/31/02, based on a target
annualized bonus of $200,000.00, of which $50,000.00 is guaranteed. Your FY03
bonus potential will be $200,000.00, of which uBid will guarantee $100,000.00,
provided that you are employed by uBid on the date that bonuses are paid under
the FY03 Bonus Plan, to be approved by the uBid Board of Directors. This bonus
will be based on successful satisfaction of fiscal year 2003 business and
personal objectives pursuant to the terms and conditions of the FY2003 Bonus
Plan.

In addition, on your date of hire, you will be granted an option (the "Option")
to purchase 300,000 shares of CMGI common stock under the CMGI 2000 Stock
Incentive Plan (the "Plan"). The Option will vest as follows: 25% on the one
year anniversary of the date of grant, and then 1/48/th/ of the total award will
vest monthly until fully vested on the fourth anniversary of the date of grant.
The exercise price of the Option shall equal the closing price of the CMGI
common stock on the Nasdaq National Market (during normal trading hours) on the
date of grant. The Option shall be subject to all terms, limitations,
restrictions and termination provisions set forth in the Plan and in the
separate option agreement (which shall be based upon CMGI's standard form of
option agreement) that shall be executed to evidence the grant of the Option.
Additionally, as a condition of employment with uBid, you are required to
execute each of the enclosed Non-Competition Agreement and Non-Disclosure and
Developments Agreement.

Please be advised that as President and Chief Executive Officer of uBid, you
shall be deemed to be an "executive officer" of CMGI within the meaning of Rule
3b-7 under the Securities Exchange Act of 1934, as amended, and an "officer" of
CMGI within the meaning of Rule 16a-1(f) under such Act. More details regarding
the reporting requirements and other obligations imposed on you by federal
securities laws will be forthcoming from a member of CMGI's Legal Department.

As an employee of uBid, you may participate in any and all bonus and benefit
programs that uBid establishes and makes available to its employees from time to
time, provided you are eligible under (and subject to all provisions of) the
plan documents governing those programs. Details of the benefits offered will be
reviewed with you in orientation on your first day of employment.
