SECOND AMENDMENT

Landlord (as successor in interest to EOP-Northwest Properties, L.L.C., a Delaware limited liability company) and Tenant are parties to that certain lease dated March 1, 2005, which lease has been amended by that certain First Amendment dated November 10, 2006 (the “First Amendment”) (as amended, the “Lease”). Pursuant to the Lease, Landlord has leased to Tenant space currently containing approximately 33,842 rentable square feet (the “Existing Premises”) described as Suites 4100 and 4600 on the 41^st and 46^th floors of the building commonly known as Wells Fargo Center, located at 999 Third Avenue, Seattle, Washington (the “Building”).

Tenant has requested that additional space consisting of (i) approximately 2,259 rentable square feet described as Suite 4160 on the 41^st floor of the Building as shown on Exhibit A-1 hereto (the “Suite 4160 Expansion Space”), (ii) approximately 1,298 rentable square feet described as Suite 4120 on the 41^st floor of the Building as shown on Exhibit A-2 hereto (the “Suite 4120 Expansion Space”), and (iii) approximately 9,090 rentable square feet described as Suite 3700 on the 37^th floor of the Building as shown on Exhibit A-3 hereto (the “Suite 3700 Expansion Space”, and together with the Suite 4160 Expansion Space and the Suite 4120 Expansion Space, each, individually, a “Second Expansion Space”) be added to the Premises and that the Lease be appropriately amended and Landlord is willing to do the same on the following terms and conditions.

As used herein, “Second Expansion Effective Date” means, for each Second Expansion Space, the Applicable Target Second Expansion Effective Date (defined below); provided, however, that the Second Expansion Effective Date shall be delayed to the extent that (a) Landlord fails to deliver possession of such Second Expansion Space to Tenant for any reason, including but not limited to, holding over by prior occupants, or (b) the substantial completion of the Landlord Work (defined in Exhibit C attached hereto) in such Second Expansion Space is delayed beyond the Applicable Target Second Expansion Effective Date solely as a result of Landlord’s failure to use commercially reasonable efforts, in accordance with the terms of this Amendment and without paying overtime rates, to substantially complete such Landlord Work as soon as reasonably possible after final approval of the applicable Plans (defined in Exhibit C attached hereto). As used herein, “Applicable Target Second Expansion Effective Date” means: (a) with respect to the Suite 4160 Expansion Space, August 1, 2006; (b) with respect to the Suite 4120 Expansion Space, December 1, 2006; and

(c) with respect to the Suite 3700 Expansion Space, June 1, 2007. For purposes of this Section 1.02, the Landlord Work in each Second Expansion Space shall be deemed to be substantially completed on the date that Landlord reasonably determines that such Landlord Work has been performed, other than any details of construction, mechanical adjustment or any other matter the non-completion of which does not materially interfere with Tenant’s use of such Second Expansion Space. Any delay in any Second Expansion Effective Date pursuant to this Section 1.02 shall not subject Landlord to any liability for any loss or damage resulting therefrom. The actual Second Expansion Effective Date for each Second Expansion Space shall be set forth in a confirmation letter to be prepared by Landlord substantially in the form of Exhibit B hereto. If any Second Expansion Effective Date is delayed, the Extended Termination Date shall not be similarly extended.

Second Expansion Effective Date – 02/28/13

Second Expansion Effective Date – 02/28/13

Second Expansion Effective Date – 02/28/13

Suite 4120 Expansion Space. For the period commencing with the Second Expansion Effective Date for the Suite 4120 Expansion Space and ending on the

Extended Termination Date, Tenant’s Pro Rata Share for the Suite 4120 Expansion Space shall be 0.1380%.

This Amendment and the attached exhibits, which are hereby incorporated into and made a part of this Amendment, set forth the entire agreement between the parties with respect to the matters set forth herein. There have been no additional oral or written representations or agreements. Under no circumstances shall Tenant be entitled to any Rent abatement, improvement allowance, leasehold improvements, or other work to the Premises, or any similar economic incentives

that may have been provided Tenant in connection with entering into the Lease, unless specifically set forth in this Amendment. Tenant agrees that neither Tenant nor its agents or any other parties acting on behalf of Tenant shall disclose any matters set forth in this Amendment or disseminate or distribute any information concerning the terms, details or conditions hereof to any person, firm or entity without obtaining the express written consent of Landlord

Commencement Letter with respect to that certain Second Amendment (the “Second Amendment”) dated as of                     , 2006, by and between WA-999 THIRD AVENUE, L.L.C., a Delaware limited liability company, as Landlord, and Zillow, Inc., a Washington corporation, as Tenant, for new or additional premises on the 41^st and 37^th floors of the building located at 999 Third Avenue, Seattle, Washington.

EXHIBIT – DO NOT SIGN

If Landlord’s estimate and/or the actual cost of construction for any Second Expansion Space shall exceed the Allowance for such Second Expansion Space, Landlord, prior to commencing any construction of Landlord Work in such Second Expansion Space, shall submit to Tenant a written estimate setting forth the anticipated cost of such Landlord Work, including but not limited to labor and materials, contractor’s fees and permit fees. Within 3 Business Days thereafter, Tenant shall either notify Landlord in writing of its

approval of the cost estimate, or specify its objections thereto and any desired changes to such proposed Landlord Work. If Tenant notifies Landlord of such objections and desired changes, Tenant shall work with Landlord to reach a mutually acceptable alternative cost estimate.

Tenant acknowledges that the Landlord Work for each Second Expansion Space may be performed by Landlord during Building Service Hours after the applicable Second Expansion Effective Date. Landlord and Tenant agree to cooperate with each other in order to enable the Landlord Work in each Second Expansion Space to be performed in a timely manner and with as little inconvenience to the operation of Tenant’s business therein as is reasonably possible. Notwithstanding anything herein to the contrary, but subject to Section 1.02 of the Amendment, any delay in the completion of the Landlord Work in any Second Expansion Space and any inconvenience suffered by Tenant

during the performance of such Landlord Work shall neither delay the applicable Second Expansion Effective Date nor subject Landlord to any liability for any loss or damage resulting therefrom or entitle Tenant to any credit, abatement or adjustment of Rent or other sums payable under the Lease.
