                              LEASE AMENDMENT NO. TWO

Lease Amendment No. Two to be attached to and form a part of that lease
(which together with any amendments, modifications and extensions thereof is
hereinafter called the "Lease") made on the 30th day of September, 1996
between SPIEKER PROPERTIES L.P., a California limited partnership (successor
in interest to BPG Pasadena, L.L.C., a Delaware Limited Liability Company) as
Landlord and CITYSEARCH, INC., a Delaware Corporation, as Tenant, for the
premises commonly known as 790 East Colorado Boulevard, Pasadena, CA 91101
(the "Project").

Effective December 1, 1998, the above described Lease shall be modified as
follows:

RENTABLE AREA. Upon the effective date of December 1, 1998 through March 31,
2002, Tenant's Rentable area shall also include the Premises (approximately
2,491 rentable square feet), commonly known as 790 East Colorado Blvd., Suite
103, Pasadena, CA 91101 (the "Project"), as shown outlined in red on the
attached Exhibit "A". Therefore from December 1, 1998 through March 31, 2002,
Tenant's total Rentable Area shall be 30,053 rentable square feet.

RIGHT TO PRIOR OCCUPANCY. Tenant has requested early occupancy and use of the
Expansion Space on an intermittent basis during the period from October 1,
1998 through October 25, 1998. Landlord is willing to permit such early
occupancy and use. Such early occupancy and use by Tenant shall be on all the
terms and conditions set forth in the Lease, as amended hereby, except that
the rent owed by Tenant for the Expansion Space during such early occupancy
period shall be $2,366.50. Tenant agrees to surrender possession of the
Expansion Space to Landlord immediately following the end of such early
occupancy period, so that Landlord can perform its improvement work as
described below.

Tenant acknowledges that as a result of such early occupancy by Tenant,
Landlord will not be able to commence the improvements to the Expansion Space
required of Landlord pursuant to TENANT IMPROVEMENTS Section herein
("Landlord's Work") until on or after October 26, 1998, that such
improvements will take approximately eight weeks, or more, to complete, and
that it may not be practical or cost-effective to schedule such work over the
Thanksgiving weekend or during the period from the day before Christmas
through New Year's Day. Accordingly, Tenant agrees that Tenant's regular
monthly obligations for rent and rent escalation's for the Expansion Space as
described in BASIC MONTHLY RENTAL shall commence on December 1, 1998,
irrespective of the fact that Landlord has not then completed Landlord's Work
and tendered possession of the Expansion Space back to Tenant. Landlord
agrees to complete Landlord's Work as soon as practical on a commercially
reasonable basis, as determined by Landlord in its reasonable discretion, but
without any obligation to incur liability for overtime or other premium
payments.

In the event that Landlord does not complete Landlord's Work and tender
possession of the Expansion Space to Tenant by January 1, 1999, then Tenant
shall be entitled to an equitable abatement of rent and rent escalation's for
the Expansion Space, as reasonably calculated by Landlord for the number of
days of such delay after January 1, 1999, until the date that Landlord does
complete Landlord's Work and tender possession of the Expansion Space to
Tenant; provided, however, that Tenant shall receive no such rental abatement
for any portion of such delay that was caused by the acts or omissions of
Tenant.  Such rental abatement shall be Tenant's sole and exclusive remedy for
any delay by Landlord in completing Landlord's Work and tendering possession
of the Expansion Space to Tenant.

BASIC MONTHLY RENTAL. The Basic Monthly Rental shall increase to the
following amounts to reflect the inclusion of the Premises:
