         The undersigned understands that Morgan Stanley & Co. Incorporated

several Underwriters, including Morgan Stanley (the "Underwriters"), of shares
(the "SHARES") of the Common Stock, par value $.001 of the Company (the "COMMON

         To induce the Underwriters that may participate in the Public Offering
to continue their efforts in connection with the Public Offering, the
undersigned hereby agrees that, without the prior written consent of Morgan
Stanley on behalf of the Underwriters, it will not, during the period commencing
on the date hereof and ending 180 days after the date of the final prospectus,
relating to the Public Offering (the "PROSPECTUS"), (1) offer, pledge, sell,

of contract to sell, grant any option, right or warrant to purchase, lend, or
otherwise transfer or dispose of, directly or indirectly, any shares of Common

Shares to the Underwriters pursuant to the Underwriting Agreement or (b)

registration of any shares of Common Stock or any security convertible into or
exercisable or exchangeable for Common Stock.

         Whether or not the Public Offering actually occurs depends on a number
of factors, including market conditions. Any Public Offering will only be made
pursuant to an Underwriting Agreement, the terms of which are subject to
negotiation between the Company and the Underwriters.

                           SECOND AMENDMENT TO LEASE

      THIS SECOND AMENDMENT TO LEASE (the "Amendment") is made and entered into
this 30th day of November, 1999, by and between MERRILL PLACE, LLC, a
Washington limited liability company ("Landlord"), and FREESHOP.COM, INC.
("Tenant").

      RECITALS:

      A.    On the 23rd day of September, 1997, Landlord and Tenant entered
into a Lease Agreement (the "Lease"), which Lease provides for the lease by
Landlord to Tenant of certain premises consisting of 9,670 square feet of
office floor area on the third floor and 2,117 square feet of balcony floor
area (the "Original Premises") of the Schwabacher Warehouse Building located at
95 South Jackson Street, Seattle, King County, Washington (the "Warehouse
Building").

      B.    Pursuant to an Amendment to Lease dated February 16, 1999 (the
"First Amendment"), Tenant agreed to lease additional space (the "First
Additional Space") on the second floor of the Warehouse Building consisting of
8,374 square feet of office space and 1,211 square feet of office space on the
first floor.

      C.    Tenant has exercised its right of first opportunity to lease
additional space in the Warehouse Building pursuant to Paragraph 36 of the
Lease.

      D.    The parties hereto desire by these presents to amend the Lease in
certain respects to reflect the lease of such additional space by Landlord to
Tenant.

      NOW, THEREFORE, for and in consideration of the recitals, which are
incorporated herein, and other good and valuable consideration, the parties
hereto agree that the Lease shall be, and the same is hereby amended as follows:

      1.    Additional Space. Landlord hereby leases to Tenant, and Tenant
hereby leases from Landlord, approximately 1,518 rentable square feet of floor
area on the first floor and 8,000 rentable square feet of floor area in the
basement of the Warehouse Building (the "Second Additional Space") (hereinafter
the Original Premises, the First Additional Space and the Second Additional
space are collectively called the "Premises"), upon the same terms and
conditions contained in the Lease, except as provided otherwise herein. The
Second Additional Space is shown on the drawing attached hereto as Exhibit A
and incorporated herein by this reference.

      2.    Rentable Area. The exact measurement of the Second Additional Space
will be computed by an AIA architect based upon BOMA standards and, upon
completion, the parties will execute an addendum to this Amendment setting
forth the actual square footage of the Premises and the percentage of square
footage of the Premises compared to the area of the Warehouse Building utilized
for office space.

                                      -1-

     3.  Commencement Date for Second Additional Space. The Lease commencement
date for the Second Additional Space (the "Commencement Date for the Second
Additional Space") shall be the later to occur of February 15, 2000, or the
date of substantial completion of the Tenant Improvements (defined below);
provided that if Tenant causes delays in the construction schedule set forth in
paragraph 9 below, the Commencement Date for the Second Additional Space will
be February 15, 2000.

     4.  Expiration Date. The expiration date of the Lease is hereby extended
from May 31, 2003 to May 31, 2004 (the "Termination Date"). All of Tenant's
rights to lease the Premises will terminate on the Termination Date.

     5.  Early Termination. Tenant may terminate the Lease upon the second and
third anniversary of the Commencement Date for the Second Additional Space, at
no additional cost to Tenant, provided that Tenant gives at least 270 days
prior written notice to Landlord. Notwithstanding the foregoing, this early
termination right is contingent upon Landlord's not being able to provide
Tenant with additional expansion space within Merrill Place to meet Tenant's
expansion requirements set forth in Tenant's termination notice. This paragraph
supersedes all termination rights under the Lease as amended by the First
Amendment.

     6.  Rent for Additional Space. Tenant shall pay Landlord rent based on the
following schedule for all occupied office space commencing on the Commencement
Date for the Second Additional Space:

          b.   Landlord will upgrade and add new HVAC equipment into the Second
Additional Space at its sole cost, but distribution from each heat pump unit is
part of the Tenant Improvement costs per industry standards. The HVAC fresh air
duct will remain in its current location as it serves the entire building.

     9.   Tenant Improvements. Landlord will construct all improvements to the
Second Additional Space requested by Tenant (the "Tenant Improvements")
according to plans and specifications approved by Landlord and Tenant; provided
that the Tenant Improvements to the server room on the first floor will include
finished walls only. The Commencement Date for the Second Additional Space of
February 15, 2000 is contingent upon Landlord's and Tenant's meeting the
following construction schedule:

     NOVEMBER 30, 1999. Tenant's architect will deliver to Landlord an approved
set of permit-ready construction documents initialed by Tenant. Landlord will
review said documents for completeness and then submit them to the City of
Seattle for building permits immediately upon Landlord's approval of the
drawings.

Tenant acknowledges that demolition and construction of the Tenant Improvements
to the Second Additional Space could cause some inconvenience to its current
occupancy of the Original Premises and First Additional Space.

Upon issuance of the building permit, construction of the Tenant Improvements
will begin.

     FEBRUARY 15, 2000. Anticipated delivery date of Second Additional Space.

     Landlord agrees to obtain a minimum of two (2) construction bids from
qualified contractors, and to select the lowest bid, subject to bid
qualification by Landlord. Tenant shall have the right to review Landlord's
decision.

     10.  Tenant Improvement Allowance. Landlord will provide Tenant with an
improvement allowance for the Tenant Improvements in the Second Additional
Space of $10.00 per rentable square foot of the Second Additional Space. Tenant
agrees to pay, on or before the Commencement Date for the Second Additional
Space, for all costs of the Tenant Improvements in excess of this tenant
improvement allowance.

     11.  Parking. Paragraph 1(h) of the Lease is hereby amended to read as
follows:

          (h)  PARKING. During the term of this Lease, Landlord will provide
     parking stalls for up to twenty-seven (27) cars on a nonreserved basis for
     ninety percent (90%) of the posted market rental rate. Landlord will also
     provide Tenant with one (1) Executive Reserved parking space at the same
     rental rate. Additional monthly parking stalls may be available to Tenant's
     employees and visitors on a first come, first served basis.

other terms and conditions of the Lease, as amended by the First Amendment,
