                       Services and Promotion Agreement

          This Services and Promotion Agreement (this "Agreement") is made as of
December 22, 1999 (the "Effective Date"), by and between Snowball.com, Inc., a
Delaware corporation with principal offices at 250 Executive Park Boulevard,
Suite 4000, San Francisco, CA 94134 ("Snowball") and X-drive, Inc., a Delaware
corporation with principal offices at 3002 Pennsylvania Avenue, Santa Monica,
CA, 90404 ("X:drive").

                                  Background

          Snowball owns and operates a network of sites on the World Wide Web,
including four hub sites located at IGN.com ("IGN"), Chickclick.com
("Chickclick"), PowerStudents.com ("PS") and InsideGuide.com ("IS") (each, a
"Snowball Site" and collectively, the "Snowball Sites").  The Snowball Sites
connect to a network of affiliates sites (the "Affiliate Sites") operated by
Snowball's affiliates (collectively, "Snowball Affiliates") to provide a greater
breadth and depth of entertainment content.  The Snowball Sites and the
Affiliate Sites are sometimes referred to, collectively, in this Agreement as
the "Snowball Network."

          X:drive provides a Web-based file hosting and file management solution
that allows users to store and access information through an on-line account
with X:drive as easily as if that information were stored locally (the "X:drive
Service").  X:drive currently provides the X:drive Service through its World
Wide Web site located at www.xdrive.com (the "X:drive Site").

          X:drive wishes to be the exclusive provider of Web-based file hosting
and file management solutions on the Snowball Sites and to provide the X:drive
Service to users of the Snowball Sites.  Snowball wishes to have X:drive provide
the X:drive Service to its users and has agreed to promote X:drive as the
exclusive provider of file hosting and file management solutions on the Snowball
Sites.  Snowball has also agreed to establish a program to encourage Snowball
Affiliates to place similar links on each of the Snowball Affiliates Sites (the
"X:drive Program"), subject to the terms and conditions of this Agreement.

          Now Therefore, the parties agree as follows:

          1.  X:drive Service.
              ---------------

              (a) Provision of Service.  Each registered user of a Snowball Site
                  --------------------
(each, a "Registered User") will be provided access, at no charge, to a personal
X:drive Service account (each, a "Service Account"), through which the
Registered User will be entitled to store and access data using the X:drive
Service.  Subject to the provisions of Section 9 (User Data), when a Registered
User activates its Service Account, Snowball will provide X:drive with certain
data concerning such Registered User as further described in Exhibit A (the
                                                             ---------
"Registration Data") for X:drive's own internal use.  Upon receipt of the
Registration Data, X:drive will immediately activate the Service Account for the
applicable Registered User.  X:drive shall provide the X:drive Service to
<PAGE>

all Registered Users who activate their Service Accounts throughout the term of
this Agreement.

          (b) Development of Snowball Features.  X:drive will implement a
              --------------------------------
dedicated folder for each Snowball Site in the storage menu of the X:drive
Service (the "Folders"), as further described in this subsection.  The
applicable Snowball Site's Folder will appear to the Registered Users from that
Snowball Site.  If requested by Snowball, each Folder will contain information
and promotions to be provided by Snowball specific to the Snowball Site used by
the applicable Registered User.  For example, if the Registered User accesses
her Service Account from ChickClick.com, the Folder that appears will be named
in a manner specific to ChickClick.com and will contain information and
promotions specific to the users of ChickClick.com (if such materials are
provided to X:Drive by Snowball).  All of the content and names of each of the
Folders shall be provided by Snowball and shall be subject to the terms and
conditions of Section 7(f).  X:drive's activities under this subsection will be
mutually agreed to by the parties and described in a specification to be
attached to this Agreement as Exhibit B.
                              ---------

          (c) Development of Log-In Page.  Snowball will develop, host and
              --------------------------
maintain a page through which Registered Users will be able to activate and
access their respective Service Accounts ("Log-In Page").  The Log-In Page will
link to the Service Page as described in subsection (d) below.

          (d) Service Page.  X:drive will develop, host and maintain the co-
              ------------
branded service page through which a Registered User can activate their Service
Account (the "Service Page"), at its expense and as further described in this
subsection.  A mock-up of the Service Page is attached hereto as Exhibit C-1.
                                                                 -----------
Any content other than the Snowball Marks appearing on the In-Box Page is
hereinafter referred to as the "X:drive Content."  X:drive will implement and
maintain links from the Service Page to the Snowball Site from which the
applicable Registered User has linked.  Each link to the Snowball Site will be
indicated by, and in the form of, one of the logos or other trademarks attached
hereto as Exhibit D (the "Snowball Marks").  X:drive will implement certain
          ---------
tracking images provided to X:drive by Snowball to enable Snowball to measure
impressions and click-throughs with respect to the Service Page.  Subject to the
provisions of Section 9 (User Data), for each Registered User that activates its
Service Account, X:drive will provide Snowball with the information further
described in Exhibit A for Snowball's own internal use ("X:drive Data").
             ---------

          (e) Sales.  Snowball shall be entitled to sell advertising or other
              -----
promotions that will appear on the Service Page or in the Folders accessible by
each Registered User through the X:drive Service (collectively, "Folder Sales").
Snowball will serve all of the banner advertisements to the Service Page in
accordance with the mock-up set forth in Exhibit C-1, as such may be modified by
                                         -----------
the parties from time to time.  X:drive will cooperate with Snowball to
implement the delivery of any such advertising or promotion, as reasonably
requested by Snowball.  X:drive will deliver any advertising and promotions to
the Folders, as reasonably requested by Snowball.  Revenues from the Folder
Sales will be shared by the parties as set forth in Section 6(c).

will appear on the home page of each of the Snowball Sites.  A mock-up of the
Service Links and their appearance on the home pages of the Snowball Sites is

                   -----------

the Service Links in its discretion, provided that any such changes do not

position prior to Snowball's changes.  Snowball will also implement banner
advertisements promoting the X:drive Service that will appear on a rotating
basis on the Snowball Sites and Affiliate Sites in accordance with Exhibit F.
                                                                   ---------

registering for one of the Snowball Sites.  These emails shall be sent out at

as of November 15, 1999, the Snowball Sites had One Million Fifty Thousand Eight
Hundred Ninety Seven (1,050,897) Registered Users, which constitutes 24.3% of

     3.   Exclusivity.
          -----------

          (a) Standback.  Subject to the terms and conditions of this Agreement,
              ---------
Snowball will identify X:drive as Snowball's "exclusive file hosting and file
management provider" (or other identification as agreed to by the parties) on
each Snowball Site.  Snowball will not, during the term of this Agreement, enter
into any agreement with respect to any of the sites described on Exhibit E
                                                                 ---------
(each, a "X:drive Competitor") to promote such X:drive Competitor as a Snowball
recommended provider of Web-based file hosting and file management services or
to establish a promotional program for Snowball Affiliates similar to the
X:drive Program.  Exhibit E may be augmented during the term of this Agreement
                  ---------
by mutual agreement of the parties.  Notwithstanding the foregoing, Snowball
will be free to display advertisements (including links) on the Snowball Network
that promote other companies that provide services similar to the X:drive
Service and to include such advertisements in emails or newsletters distributed
by Snowball.

          (b) Right of First Refusal.  For the term of this Agreement, in the
              ----------------------

to the terms and conditions of this subsection.  Snowball will notify X:drive of
any prospective sale of advertising inventory to a X:drive Competitor including
the amount of inventory proposed to be sold, the price and any other relevant
terms and conditions ("Sale Notice").  Upon written notice to Snowball, X:drive
will be entitled to purchase such inventory on the terms and conditions
contained in the Sale Notice, provided that X:drive's notice is received by
Snowball within 2 business days of the date of the Sale Notice.  If X:drive
exercises its rights to purchase under this subsection, Snowball will not sell
the inventory identified in the Sale Notice to the applicable X:drive
Competitor.  If X:drive does not exercise its rights under this subsection with
respect to a particular Sale Notice within the time frames described herein,
Snowball will be free to complete the transaction described in that Sale Notice.

          -----------
obligations described in this Agreement, provide to X:drive the minimum number

Impressions described in this Section, as X:drive's sole and exclusive remedy

                                       **Confidential treatment has been
                                       requested with respect to the information
                                       contained within the "[**]" markings.

                                       from this filing and have been filed

              ---------------

the Snowball Affiliate's participation.  X:drive acknowledges that Snowball

          (b) No Solicitation.  X:drive will not, for the term of this
              ---------------
Agreement, solicit any Snowball Affiliate that has joined the X:drive Program to
engage in any kind of linking, co-branding or ecommerce business relationship
directly with X:drive.  The provisions of this Section are not intended to
impose any other restrictions on X:drive, except as expressly provided herein.

     6.   Payment.
          -------

          (a) Definitions.  Achieving "Implementation" with respect to any of
              -----------
the Snowball Sites means either: (a) Snowball has actually provided access to
the X:drive Service on the applicable Snowball Site or (b) Snowball would have
been able to provide access to the X:drive Service on the applicable Snowball
Site were it not for X:drive's failure to deliver any technical information,
content or other materials within the time periods reasonably requested by
Snowball or to otherwise perform its obligations under this Agreement.  "Initial
Implementation Date" means the first date to occur of the following: (1) the
first date a Registered User is able to access the X:drive Service on any of the
Snowball Sites; or (2) the date a Registered User would have been able to access
the X:drive Service any of the Snowball Sites were it not for X:drive's failure
to deliver any technical information, content or other materials within the time
periods requested by Snowball or to otherwise perform its obligations under this
Agreement.  Snowball will notify X:drive of the actual date that constitutes the
Implementation Date for each of the Snowball Sites at least three (3) days prior
to such date.

          (b) Flat Fee.  X:drive will pay Snowball a monthly fee of $[**]

this subsection, all remaining payments will be due each calendar month
thereafter on the same day of the month as the Initial Implementation Date (e.g.
if the Initial Implementation Date is January 10/th/, 2000, each subsequent
payment will be due on the 10/th/ day of the applicable calendar month). In the
event the Implementation for all of the Snowball Sites has not occurred within
thirty (30) days of the Initial

                                       **Confidential treatment has been
                                       requested with respect to the information
                                       contained within the "[**]" markings.
                                       Such marked portions have been omitted
                                       from this filing and have been filed

          (c) Registered Users.  In addition to the flat fee described above,
              ----------------
X:drive will pay Snowball, on a monthly basis, the amounts described in Exhibit
                                                                        -------
G.  X:drive will make all payments to Snowball due under this Section within
-
thirty (30) days of the end of the applicable calendar month.

          (d) Revenue Share.  The parties will share, on a [**] basis,
              -------------
any revenues derived from the Folder Sales and sales of advertisements on the
Service Page and actually received by Snowball (less taxes and sales commissions
up to [**], collectively, the "Revenues").  Each party will pay the other party
the other party's share of the Revenues within thirty days of the calendar month
in which such Revenues were received.

          (e) Other Payment Terms.  Each payment will include a report setting
              -------------------
forth all of the information needed to calculate the fees payable for that
period.  Payments made under this Agreement after the applicable due date will
incur interest at a rate equal to [**] per month or the highest rate permitted
by applicable law, whichever is lower.

          (f) Taxes.  All amounts payable under this Agreement are exclusive of
              -----
all sales, use, value-added, withholding, and other taxes and duties.

          (g) Records and Audit Rights.  Each party will keep all records
              ------------------------
relating to all payments made hereunder for a period of three years after the
termination of this Agreement.  An independent certified public accountant
selected by the other party may, no more than once per year and upon at least
two weeks' notice, inspect such records during normal business hours.  If, upon
performing such audit, it is determined that a party has underpaid the other
party by an amount greater than 5% of the payments due to such party in the
period being audited, then the audited party will bear all reasonable expenses
and costs of such audit in addition to its obligation to make full payment under
this Section.

     8.     Confidential Information.
            ------------------------

          (a) Obligations.  Each party ("Receiving Party") agrees to treat as
              -----------
confidential all proprietary information disclosed to it by the other party
("Disclosing Party") including marketing information, customer data, and the
terms of this Agreement ("Confidential Information").  Receiving Party agrees
not to publish or disclose the Disclosing Party's Confidential Information to
others except to those employees and subcontractors to whom disclosure is
necessary in order to carry out the purposes of this Agreement.  All tangible
materials embodying such Confidential Information will remain the sole property
of Disclosing Party and will be delivered to Disclosing Party by Receiving Party
upon Disclosing Party's request.  Receiving Party will inform all its employees
and subcontractors who receive Confidential Information of the confidential
nature of

                                       7
<PAGE>

such Confidential information and of their obligation to keep same confidential
and not to use it other than as permitted hereunder. The Receiving Party may
disclose the terms and conditions of this Agreement for due diligence purposes
as reasonably required by any financing or potential acquisition. For purposes
of this Agreement, the Registration Data shall be deemed the Confidential
Information of Snowball and the X:drive Data shall be deemed the Confidential
Information of X:drive. Throughout the term of this Agreement, X:drive shall use
the same level of care to protect the confidentiality of the Registration Data
that X:drive uses to protect the data of its other users, which in no event will
be less than reasonable care.

          (b) Exceptions.  Neither party will have any obligation with respect
              ----------
to any Confidential Information which: (1) was rightfully known to Receiving
Party prior to receipt of such Confidential Information from Disclosing Party;
(2) is lawfully obtained by Receiving Party from a third party under no
obligation of confidentiality; (3) is or becomes generally known or available
without any act or failure to act by Receiving Party; (4) is developed
independently by Receiving Party.  Either party may disclose the Confidential
Information of the Disclosing Party if required by court order or legal
requirement and the party subject to the order has given the other party a
reasonable opportunity (and has cooperated fully) to contest or limit the scope
of such required disclosure (including application for a protective order).

     9.   User Data.
          ---------

          (a) Ownership.  Subject to the restrictions in this Section and any
              ---------
rights to use the applicable data granted under this Agreement, Snowball will
own the Registration Data and X:drive will own the X:drive Data.

          (b) Treatment of Individually Identifiable User Data.  Neither party
              ------------------------------------------------
shall sell, disclose, transfer, or rent any user data obtained by it from the
other party which data identifies, or can be used to identify, a specific
individual ("Individually Identifiable User Data") to any third party or use any
Individually Identifiable User Data on behalf of any third party, without the
express permission of the applicable user specifically approving such use.  Each
of Snowball and X:drive will only use Individually Identifiable User Data in
accordance with the Terms of Service and Privacy Policy posted on the Snowball
Sites, as such may be amended from time to time by Snowball; provided that, if
any Registered User "opts-in" to receive information and promotional materials
from X:drive, then X:drive will use all resulting Individually Identifiable User
Data in accordance with the X:drive Privacy Policy posted on the X:drive Site.
In those cases where permission for disclosure of Individually Identifiable User
Data has been obtained from the applicable user, each party shall use all
reasonable efforts to implement an "opt out" feature on its own behalf, and an
include and enforce through its agreements with third parties a requirement for
the inclusion of an "opt out" feature in all e-mail communications generated by,
or on behalf of, third party users of the Individually Identifiable User Data.

          (c) Aggregate Data.  Notwithstanding the restrictions above, the
              --------------
parties retain the right to use, sell, disclose, transfer, or rent any user data
as long as such user data is in an aggregate form that does not include any
Individually Identifiable User Data; provided that, neither party will

                                       8
<PAGE>

identify the other party as the source of such aggregate data.

     10.  Term and Termination.
          --------------------

          (a) Term.  Subject to the provisions of Section 4, this Agreement will
              ----
commence on the Effective Date and will, with respect to each Snowball Site,
remain in effect until [**] of Implementation Date for such Snowball Site,
unless terminated earlier under this Section 10. If so requested by either party
by written notice to the other party within thirty (30) days of the end of the
term, the parties will negotiate in good faith to renew the term of this
Agreement, subject to any changes to the terms and conditions of this Agreement
agreed to by the parties.

          (b) X:drive Termination Right.  X:drive shall be entitled to terminate
              -------------------------
this Agreement without further obligation to Snowball if fewer than [**]
Registered Users activate their Service Accounts at least once within the [**]
period commencing on the launch of the X:drive Service on the Service Page
("Trial Period"). If X:drive does not exercise its option to terminate this
Agreement within the ten (10) day period directly following the end of the Trial
Period, then the right to terminate this Agreement as described in this Section
shall automatically expire and the term shall continue until the end of the
term.

          (c) Termination for Breach or Insolvency.  Either party may terminate
              ------------------------------------
this Agreement at any time prior to the expiration of its stated term in the
event that:  the other party breaches any term or condition of this Agreement
and fails to cure such breach within thirty (30) days of written notice; or
either party becomes the subject of a voluntary petition in bankruptcy or any
voluntary proceeding relating to insolvency, receivership, liquidation, or
composition for the benefit of creditors; or either party becomes the subject of
an involuntary petition in bankruptcy or any involuntary proceeding relating to
insolvency, receivership, liquidation, or composition for the benefit of
creditors, if such petition or proceeding is not dismissed within sixty (60)
days of filing.

          (d) Effect of Termination.  X:drive's payment obligations hereunder,
              ---------------------
as well as the provisions of this Section and the following Sections will
survive any termination of this Agreement: Section 7(d) (Ownership), Section 8
(Confidential Information), Section 9 (User Data), Section 11 (Limitation of
Liability), Section 12 (Indemnification) and Section 13 (General).  Any proper
termination of this Agreement by Snowball under Section 10(b) will not limit the
accrual of damages under Section 6 (Payment) hereof; provided, however, that,
nothing herein shall be deemed to limit or waive X:drive's rights of
counterclaim regarding the satisfactory of provision of services by Snowball as
described in this Agreement.

     11.  Limitation of Liability.  EXCEPT WITH RESPECT TO ITS OBLIGATIONS UNDER
          -----------------------
SECTION 8, SECTION 9 AND SECTION 12, NEITHER PARTY WILL BE LIABLE TO THE OTHER
FOR ANY INDIRECT, EXEMPLARY, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES, OR
ANY LOSS OR REVENUE, PROFITS, OR DATA, ARISING IN CONNECTION WITH THIS
AGREEMENT, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
