1.   PARTIES

          THIS SUBLEASE, dated January 6, 2000 is made between SP INVESTMENTS
INC., a Washington corporation ("Sublessor") and INTERNET CAPITAL GROUP, INC., a
Delaware corporation ("Sublessee").

2.   MASTER LEASE AND PREMISES

          Sublessor is the tenant under a written Lease Agreement (the "Master
Lease"), dated March 13, 1995, wherein Third and University Limited Partnership,
a Washington limited partnership (hereinafter "Landlord" shall refer to Third
and University Limited Partnership, or its successor in interest) leases to
Sublessor those certain premises (the "Master Premises") consisting of
approximately 18,563 rentable square feet located on the 54th and 55th floors of
the building ("Building") commonly known as Washington Mutual Tower, 1201 Third
Avenue, Seattle, Washington situated on the real property located in the City of
Seattle, County of King, State of Washington, legally described in the Master
Lease.

3.   PREMISES

          For the entire term, as set forth in Section 4 below, Sublessor hereby
subleases to Sublessee and Sublessee subleases from Sublessor, on and subject to
the terms, conditions and reservations set forth in this Sublease, the portion
of the Master Premises consisting of 4,281 rentable square feet as shown on the
Floor Plans for the 54th floor of the Building attached hereto as Exhibit A (the
"Premises").

4.   TERM

          The term of this Sublease shall commence on the later of January 1,
2000 or two weeks after the Premises are delivered to Sublessee ("Commencement
Date"), and end on November 30, 2004 ("Termination Date"), unless otherwise
sooner terminated in accordance with the provisions of this Sublease.
Possession of the Premises ("Possession Date") shall be delivered to Sublessee
on or before January 1, 2000.  In the event the Possession Date shall not have
occurred for any reason on or before January 1, 2000, in addition to Sublessee's
other rights and remedies, Sublessee shall have the right to terminate the
Sublease upon written notice to Sublessor upon which Sublessor shall reimburse
Sublessee all monies paid by Sublessee, except if delay in Possession Date is
caused by current Sublessee wrongfully failing to vacate the Premises,
Sublessee's remedy shall be termination of this Sublease and reimbursement of
monies paid.

5.   RENT

     5.1. Base Rent. Commencing on the Commencement Date, Sublessee shall pay to
Sublessor as base rent, without deduction, setoff, notice, or demand, at the
address of Sublessor set forth below or at such other place as Sublessor shall
designate from time to time by notice to Sublessee, the sum of $16,053.75 per
month, in advance on the first day of each month of the term of this Sublease
(the "Base Rent"). The first month's rent (for the period commencing on January
15 and ending January 31 in the event the Possession Date occurs on January 1,
2000) payable by Sublessee shall be $8,026.88 and shall be payable upon
execution of this Sublease.

     5.2. Operating Costs and Taxes. In addition to base rent payable by
Sublessee to Sublessor as set forth in Section 5.1 above, commencing on January
1, 2001, Sublessee shall pay Sublessor, as additional rent, 23% of the amount by
which "operating costs" and "taxes," as such terms are defined in the Master
Lease payable by Tenant under the Master Lease exceeds operating costs and/or
taxes payable by Tenant under the Master Lease with respect to calendar year
2000 (the "Base Year"). Such additional rent shall be payable as and when
operating costs and taxes are payable by Tenant to Landlord. If the Master Lease
provides for the payment by Tenant of operating costs and taxes on the basis of
an estimate thereof, then as and when adjustments between estimated and actual
operating costs and taxes are made under the Master Lease, the obligations of
Sublessor and Sublessee hereunder shall be adjusted in a like manner, and if any
such adjustment shall occur after the expiration or earlier termination of this
Sublease, then the obligations of Sublessor and Sublessee under this Subsection
5.2 shall survive such expiration or termination. Sublessor shall promptly
furnish Sublessee with copies of all statements by Landlord of actual or
estimated operating costs and taxes during the term. In the event Sublessor is
required to pay any other additional rents or other sums pursuant to the Master
Lease which benefits the Premises and/or Sublessee's operations during the term
of this Sublease, Sublessee shall pay to Sublessor 23% of such costs incurred as
additional rent hereunder. Notwithstanding anything in this Section 5.2 to the
contrary, in the event special or extra services or utilities are requested by
Sublessee or Sublessor with respect to their use of the Premises, as applicable,
the party requesting such special or extra services or utilities shall be solely
responsible for payment of the same.

     5.3. Rent. The Base Rent payable by Sublessee pursuant to Section 5.1
above, together with additional rent payable by Sublessee pursuant to 5.2 above
and any other sums payable by Sublessee under this Sublease shall be
collectively referred to herein as "Rent."

6.   SECURITY DEPOSIT.

          As security for the performance of this Sublease by Sublessee,
Sublessee shall pay a security deposit equal to the first and last months' Base
Rent $24,080.63 upon full execution of the sublease. To the extent such funds
are not otherwise applied under the terms of this Section 6, Sublessor shall
apply such Security Deposit to Rent due for the first and last months of the
Sublease term. Sublessor may apply all or any part of the Security Deposit to
the payment of any sum in default (beyond applicable notice and cure periods) or
any other sum which Sublessor may be required or may in its reasonable
discretion deem necessary to spend or

                                      -2-
<PAGE>

incur by reason of Sublessee's default (beyond applicable notice and cure
periods). In such event, Sublessee shall, within five days of written demand
therefor by Sublessor, deposit with Sublessor the amount so applied. The amount
of the Security Deposit held by Sublessor at the expiration or sooner
termination of this Sublease and not applied by Sublessor under the provisions
of this Section 6 shall be repaid to Sublessee within 30 days after expiration
or sooner termination of this Sublease. Sublessor shall not be required to keep
any Security Deposit separate from its general funds and Sublessee shall not be
entitled to any interest thereon.

7.   USE OF PREMISES

          The Premises shall be used and occupied only for the uses allowed
under the Master Lease and for no other use or purpose.

8.   ASSIGNMENT AND SUBLETTING

          Sublessee shall not assign, mortgage, encumber or otherwise transfer
this Sublease or sublet the whole or any part of the Premises without in each
case first obtaining Sublessor's prior written consent, and the prior written
consent of the Landlord under the Master Lease, except that assignment to an
affiliate of Sublessee shall not require Sublessor's consent.  Sublessor shall
not unreasonably withhold or delay its consent under this Section 8, except that
Sublessor may withhold in its absolute and sole discretion, its consent to any
mortgage, hypothecation, pledge or other encumbrance of any interest in this
Sublease or the Premises by Sublessee or any subtenant of Sublessee, whereby
this Sublease or any interest therein becomes collateral for any obligation of
Sublessee.  In lieu of granting any such consent, Sublessor reserves the right
to terminate this Sublease, or in the case of subletting or assignment, in which
event Sublessor may elect to enter into the relationship of sublandlord and
subtenant with such proposed assignee or subtenant, based upon the rent and
other compensation and terms and conditions agreed to by such subtenant or
assignee and otherwise upon the terms and conditions of this Sublease.  If there
is a partial termination of the Sublease pursuant to this Section 8, the Rent
payable hereunder shall be reduced based upon the square footage of the area
subject to the partial termination.  In connection with each request for an
assignment or subletting, Sublessee shall pay the reasonable cost of processing
such assignment or subletting, including attorneys fees, upon demand of
Sublessor (not to exceed $1,000 in the aggregate).  Sublessee shall provide
Sublessor with copies of all assignments, subleases and assumption instruments.

9.   RIGHT OF FIRST NEGOTIATION

          If Sublessor desires from time to time, during the terms of this
Sublease, to sublease additional portions of the Master Premises to someone
other than an affiliate or business associate (i.e., someone with whom Sublessor
or one or more of its affiliates has or expects to have a business relationship
other than one of Landlord and Tenant), Sublessor shall offer Sublessee a
continuing first right to negotiate a sublease for all such additional spaces
(each, an "Additional Space").  In such event, Sublessor shall give Sublessee
written notice indicating the portion of the Master Premises that will be
available, the timing of such availability, and proposed rental terms.  In the
event Sublessee desires to sublease such Additional Space,

                                      -3-
<PAGE>

Sublessee and Sublessor shall then negotiate in good faith all terms and
conditions of an amendment to the Sublease to include such Additional Space into
the Premises. If the parties fail, for any reason, to enter into such amendment
within thirty (30) days, then Sublessor shall be free to sublease the subject
space to others upon similar terms and conditions provided, however, such terms
and conditions offered to any third party shall not be more economically
favorable than those offered to Sublessee without first offering such Additional
Space to Sublease on such favorable terms and conditions (in such case Sublessee
shall have five (5) business days of written notice to accept the offer).

10.    OTHER PROVISIONS OF SUBLEASE

          All applicable terms and conditions of the Master Lease are
incorporated into and made a part of this Sublease as if fully set forth herein
except that references to "Landlord" and "Tenant" shall mean "Sublessor" and
"Sublessee" respectively and except that the following provisions of the Master
Lease shall not be incorporated into this Sublease:

          (a)  Subsections 1(b)(c)(d)(e)(f)(g)(h) and (j) are excluded
          (b)  Exhibit C is excluded except for paragraphs 2 (as modified by
               Section 11 below), 3, 4 and 5
          (c)  Section 3 is superseded and replaced with Section 4 above
          (d)  Section 4 is excluded
          (e)  Section 5 is superseded and replaced with Section 5.1 above
          (f)  Section 10 is modified to be consistent with Section 5.2 above
          (g)  Section 27, 29 and 35(c) are excluded
          (h)  References to "Landlord" in Sections 13 and 26 of the Master
               Lease shall mean Landlord under the Master Lease only and not
               Sublessor.

          In addition, the terms and conditions of Section 21 of the Master
Lease are incorporated as if Sublessee were the Tenant and the Sublease were the
Lease; except that a non-disturbance agreement shall not be required with
respect to this sublease.

          Sublessee agrees to perform the Tenant's obligations under the Master
Lease (except such provisions as excluded or replaced as set forth above) during
the term of this Sublease, except that the obligation to pay Rent to Landlord
shall be considered performed by Sublessee to the extent Rent is paid to
Sublessor in accordance with Section 5 of this Sublease.  Sublessee shall not
commit or suffer any act or omission that will violate any of the provisions of
the Master Lease.  Sublessor shall exercise due diligence in attempting to cause
Landlord to perform its obligations under the Master Lease for the benefit of
Sublessee.

          If the Master Lease terminates for any reason, this Sublease shall
terminate and the parties shall be relieved of any further liability or
obligation under this Sublease, provided, however, that if the Master Lease
terminates as a result of a default or breach by Sublessor or Sublessee under
this Sublease and/or the Master Lease, then the defaulting party shall be liable
to the nondefaulting party for the damage suffered as a result of such
termination.  Sublessor shall not voluntarily terminate the Master Lease, except
as permitted in Sections 13 and 26 of the

                                      -4-
<PAGE>

Master Lease. Notwithstanding the foregoing, if the Master Lease gives Sublessor
any right to terminate the Master Lease in the event of the partial or total
damage, destruction, or condemnation of the Master Premises or the Building of
which the Premises are a part, the exercise of such right by Sublessor shall not
constitute a default or breach hereunder. Notwithstanding the preceding
sentence, Sublessor shall not exercise any such right to terminate the Master
Lease in the event of damage, destruction or condemnation if Sublessee agrees in
writing, prior to the date upon which such termination notice must be given, to
assume all obligations of Sublessor under the Master Lease (including the full
rent and other monetary obligations thereunder) from and after the date upon
which Sublessor had the right to terminate the Master Lease.

11.    IMPROVEMENTS TO PREMISES

          (a) Sublessor shall provide to Sublessee a $5.00 per rentable square
foot tenant improvement allowance for the work as shown on Exhibit B (the "Floor
Plan"), which shall be credited toward rent beginning the month following
completion of such improvements. Sublessee shall be responsible for any and all
costs in excess of the $5.00 per rentable square foot allowance provided by
Sublessor.

          (b) Subject to obtaining Landlord's written consent, Sublessor
consents to Sublessee's alteration of the Premises as indicated in the Floor
Plan, including the hard wall changes indicated on the Floor Plan, and changing
the existing wall color and carpet. The existing wood trim finish (including as
to color) shall not be changed, but pieces may be removed and new pieces
installed as needed to reconfigure the Premises as shown in the Floor Plan. Any
new trim pieces shall match the existing trim (including as to color) as close
as reasonably practical. Any and all tenant improvements shall be coordinated
through Landlord and are subject to the provisions of Section 11 of the Master
Lease. Sublessee shall provide additional plans and specifications for the
alterations as required by Landlord and shall not proceed with the alterations
until Landlord's written consent is obtained.

          (c) Subject to the provisions of Section 13 of the Master Lease
relating to damage and destruction, upon expiration or sooner termination of
this Lease, Sublessee shall restore the three exterior offices marked on Exhibit
C (the "Restoration Offices") to substantially the same condition as they were
in when delivered to Sublessee, except that wall paint and carpet shall match
what is then used in the rest of the private offices in the Premises.
Notwithstanding the foregoing, Sublessor may subsequently elect to waive the
requirement that the Restoration Offices be restored. Such election shall only
be effective when and if written notice of such election is given by Sublessor
to Sublessee. Unless Sublessor subsequently waives the restoration requirement,
the provisions in Section 10(c) shall control over those of Section 22 of the
Master Lease with respect to the Restoration Offices.

          (d) Sublessee may deliver to Sublessor items of wood trim, doors,
hardware and other such finish items for the Restoration Offices. Sublessor will
store such items during the term of this Sublease at its costs and return such
items to Sublessee for use in restoring the

                                      -5-
<PAGE>

Restoration Offices as required by Section 10(c). If Sublessor subsequently
waives the restoration requirements in Section 10(c), Sublessor may then dispose
of the items stored under this Section 10(d), as Sublessor deems appropriate.

          (e) If Sublessee's net worth drops below $100,000,000 (as indicated in
any publicly available financial statements) at any time during the term of this
Sublease and unless Sublessee has waived the restoration requirements in Section
10(c) of this Sublease, Sublessee shall immediately increase the Security
Deposit under Section 6 of this Sublease by $20,000. Notwithstanding the
provisions of Section 6, Sublessor shall not be required to apply the increased
deposit amount to the last month or months rent, and the increased amount may be
held by Sublessee until the Premises are returned as provided in Section 22 of
the Master Lease, as modified by Section 10(c) of this Sublease.

12.  PARKING AND SIGNAGE

          Sublessee shall be entitled to lease from Landlord four of the parking
stalls provided under Section 7 of the Master Lease during the term of this
Sublease.  Sublessee shall be entitled to building standard suite and directory
signage.

13.  BROKER PARTICIPATION

          Sublessor and Sublessee warrant and represent that they have dealt
with no real estate broker in connection with this Sublease other than Pacific
Real Estate Partners, Inc. and Washington Partners, Inc. pursuant to separate
agreements, and that no other broker is entitled to any commission on account of
this Sublease.

14.  ATTORNEY'S FEES

          If Sublessor or Sublessee shall commence an action against the other
arising out of or in connection with this Sublease, the prevailing party shall
be entitled to recover its costs of suit and reasonable attorney's fees.

15.  NOTICES

          All notices and demands which may or are to be required or permitted
to be given by either party on the other hereunder shall be in writing.  All

Lease to the extent Sublessee has not expressly agreed to perform such
obligations under the Sublease.  Sublessor, with respect to the obligations of
Landlord under the Master Lease, shall use Sublessor's diligent good faith
efforts to cause Landlord to perform such obligations for the benefit of
Sublessee.  Such diligent good faith efforts shall be satisfied by the
following: (a) upon Sublessee's written request, promptly notifying Master
Landlord of its nonperformance under the Master Lease, and requesting that
Landlord perform its obligations under the Master Lease; and (b) Sublessor shall
not unreasonably withhold consent to Sublessee to commence arbitration pursuant
to Paragraph 5 of Exhibit C of the Master Lease in Sublessor's name to obtain
the performance required from Landlord under the Master Lease; provided,
however, that if Sublessee commences an arbitration action, Sublessee shall pay
all costs and expenses incurred in connection therewith, and Sublessee shall
indemnify Sublessor against, and hold Sublessor harmless from, all reasonable
costs and expenses incurred by Sublessor in connection therewith.

17.  CONSENT BY LANDLORD

          This Sublease shall be of no force or effect unless consented to by
Landlord within 15 days after execution hereof.  Such consent shall state, and

and shall apply as between Landlord and Sublessee.
