Dear Will:

We're delighted to offer you a position with NBC Internet, Inc. The following
outlines your compensation and benefit package and other terms of your
employment.

     1.   POSITION AND DUTIES. Your title will be Chief Executive Officer. In
this role, you will report to the Board of Directors of NBCi (the "Board"),
specifically to Bob Wright, Chairman of the Board. As CEO you will be
responsible for all strategic, operational, and financial aspects of running the
Company, as well as all duties customary to such position and such duties as may
be assigned to you by the Board, and you will be held accountable for delivering
the results expected by its Board and shareholders. In addition, the Company
will recommend that you be elected as a director of the Board of NBCi. You will
devote your full business time and attention to performing your duties to the
Company, except with respect to the duties you perform as a member of the boards
of directors of the entities listed on Exhibit A to this agreement, and in
accordance with NBCi policy.

     2.   SALARY. You will be entitled to an annual base salary of $800,000,
payable bi-monthly, which equates to $30,769.23 per pay period, less standard
payroll taxes and withholdings.

     3.   BONUS. You will be entitled to an annual bonus of up to $1,200,000,
with $900,000 guaranteed, and up to $300,000 discretionary, paid based on
achievement of written business objectives to be agreed upon annually between
you and NBCi's Board. Your guaranteed bonus will be paid quarterly, and your
discretionary bonus will be paid annually following the close of the year's
financial records. This will allow for quarterly fluctuations in the Company's
performance and operating results, with an eye toward determining the
discretionary bonus based on cumulative year-end results. Your bonus will be
pro-rated for 2000 based upon the portion of the year for which you are employed
by NBCi. You must be employed by NBCi on the date any quarterly or annual bonus
is payable to be eligible to receive such bonus payment.

     4.   START DATE. Your first day of employment will be March 27, 2000.

<PAGE>

     5.   STOCK OPTIONS. You will be granted an incentive stock option to
purchase 1,000,000 shares of NBCi Class A Common Stock at an exercise price
equal to the closing price of such stock on March 24, 2000. This option will be
subject to the terms and conditions of the NBCi 1999 Stock Incentive Plan and
the provisions set forth in paragraph 11 below. This option will vest over a
three-year period, with the first one-third shares vesting upon the first
anniversary of your employment start date, and the remainder vesting in equal
monthly installments over the remaining two years.

     6.   RESTRICTED STOCK GRANT. You will be granted the number of restricted
stock shares of NBCi Class A Common Stock valued at a total of $12,000,000,
based upon such stock's closing price on March 24, 2000, at no cost to you.
These shares will vest in the following installments: 50% of the shares will
vest on the completion of your second year of employment, and the remaining 50%
will vest on the completion of your third year of employment.

     7.   BENEFITS. You will receive all benefits available to peer officers. On
the first day of the month following your start date, you will be eligible to
participate in the NBCi Medical, Dental, Vision, Life, AD&D, and Long-Term
Disability plans. These benefits are also available for your dependents. You
will be eligible to participate in the NBCi 401(k) program in the next open
enrollment period, which starts the first day of each month. You will also be
provided with a daily car and driver service, at NBCi's expense, for purposes of
your personal transport to and from your home and our headquarters office in San
Francisco (or to other business-related destinations as required).

     8.   HOUSING LOAN. NBCi will offer you an interest-free loan in the amount
of $4,000,000, immediately upon your employment start date, for the sole purpose
of purchasing a primary residence in the local San Francisco Bay Area. This loan
will be forgiven in full by NBCi, resulting in ordinary income to you, on your
third anniversary with the company. This loan will be secured by a second
mortgage on your primary residence in the Bay Area, to be held by NBCi.
Termination of your employment by NBCi for cause (as defined below), or by you
without good reason (as defined below), prior to your third anniversary will
require you to repay the loan in full to NBCi prior to your last date of
employment. Termination of your employment by NBCi not for cause, or by you with
good reason, will result in the loan being forgiven in full as of the date of
termination.

     9.   RELOCATION. NBCi will cover your reasonable and customary relocation
expenses incurred in the course of moving your family to the Bay Area in
accordance with NBCi policy. This will include, but is not limited to, brokerage
fees for the sale of your existing residence, relocation services, items such as
round trip airfare for you and your family for house-hunting trip(s) as needed,

housing and trips home for personal business and visits until your new residence
is purchased and ready for occupancy, and other related expenses.

first year of

     11.  TERM; TERMINATION. The term of this agreement shall be 3 years from
your employment start date. This agreement may be terminated by NBCi for cause
or by you for good reason on not less than 14 days' written notice. In the event
NBCi terminates this agreement for cause or you terminate this agreement without
good reason, you shall be entitled to receive only your accrued salary as of
your employment termination date, and all unvested shares of NBCi stock options
and NBCi restricted stock issued pursuant to this agreement or thereafter shall
cease vesting and be terminated or cancelled as of the employment termination
date. In the event NBCi terminates this agreement without cause or you terminate
this agreement for good reason, NBCi shall (a) immediately vest all of your
stock options and restricted stock granted pursuant to this agreement, and (b)
pay you the full amount of your base salary and guaranteed bonus through the end
of the term of this agreement, in a lump sum or series of payments, at NBCi's
discretion, and (c) forgive the loan described in paragraph 8 above; PROVIDED,

reduction; a material reduction in cash compensation; a material reduction in

the CEO of the surviving entity.

six months' notice of (a) your intention to resign your employment without good
reason during the term of this agreement, or (b) your decision not to continue
your employment with NBCi after the expiration of this Agreement where NBCi has
offered to continue your employment as CEO on terms with respect to your base
salary, bonus and benefits that are not less favorable than such terms then in
effect. You will provide this notice in writing to the Chairman of the NBCi
Board, with a copy to NBCi's Senior Vice President of Human Resources. You
acknowledge that your failure to give NBCi such notice shall cause NBCi to
suffer material and irreparable harm, and therefore NBCi shall be entitled to
