Free Customizable Lease Forms

  • Commercial Lease. Start a state-specific lease for the rental of commercial property. Specify the term and rent due, as well as whether the landlord or tenant is responsible for property taxes, insurance, and maintenance and repairs.
  • Commercial Sublease. When a tenant vacates commercial property before the lease term has expired, it may be able to rent the premises to a third party. The tenant would be the sublessor and the third party would be the sublessee. Besides preparing a sublease, both parties will want to review the provisions for assignment or subletting in the original lease agreement between the landlord and the sublessor.
  • Sublease Agreement. Tenants of residential property should prepare a sublease agreement if they are seeking to sublease a room or the entire apartment or house to a third party. All parties should review the original lease agreement to see if there are any restrictions on subletting or assigning the premises.
  • Triple Net Lease. Triple net leases are a type of commercial leases where the tenant has to pay for property taxes, insurance, utilities, and maintenance, in addition to the monthly rent.
  • Office Space Lease. When renting an office space, tenants should understand the amount of the rent and duration of the lease. Other important terms include whether the space can be subleased, which parties are responsible for maintenance, and whether any furniture and furnishings will be provided.

     4.   Expansion Option. Section 2 of the Third Amendment is hereby deleted
in its entirety and the following is substituted in its place and stead:

     (a)  For purposes of this Section 4, "Expansion Option" shall mean either
Option #1 (as hereinafter defined) or Option #2 (as hereinafter defined) as the
case may be or the context requires and "Option Space" shall mean either Option
Space #1 (as hereinafter defined) or Option Space #2 (as hereinafter defined) as
the case may be or the context requires.

     (b)  Option #1. Lessee shall have an option ("Option #1") to lease all (but
not less than all) of that certain office space on the fourteenth (14th) floor
of the Building ("Option Space #1") consisting of approximately 7,765 rentable
square feet and designated as "Option #1" on Exhibit A attached hereto and by
this reference made a part hereof. Option #1 may be exercised at any time on or
before March 31, 1998, by written notice from Lessee to Lessor ("Lessee's
Notice"). If Option #1 is exercised on or before December 31, 1997, the lease
term for Option Space #1 shall commence on the earlier to occur of (1) the date
Lessee first occupies all or any portion of Option Space #1 for any use or
purpose other than Lessee's construction of leasehold improvements therein, (2)
one hundred twenty (120) days after the date Lessor delivers possession of
Option Space #1 to Lessee, unless Lessee's Notice specifies an earlier date, or
(3) April 1, 1998, and Lessor shall deliver possession of Option Space #1 to
Lessee, for the purpose of Lessee's construction of leasehold improvements
therein, on the later to occur of (x) one hundred twenty (120) days after the
date Lessee's Notice is delivered to Lessor (but in no event later than April 1,
1998) or (y) one hundred twenty (120) days prior to the date specified in
Lessee's Notice, if any, as the commencement date for the lease term for Option
Space #1, or if no such date is specified, December 1, 1997. If Option #1 is
exercised after December 31, 1997, the lease term for Option Space #1 shall
commence on the earlier to occur of (i) the date Lessee first occupies all or
any portion of Option Space #1 for any use or purpose other than Lessee's
construction of leasehold improvements therein, (ii) the date of commencement of
such term as specified in Lessee's Notice or (iii) April 1, 1999.

     (c)  Option #2. If (but only if) Lessee exercises Option #1 on or before
December 31, 1997, Lessee shall have an option ("Option #2") to lease all (but
not less than all) of that certain office space ("Option Space #2") on the
fourteenth (14th) floor of the Building consisting of approximately 8,428
rentable square feet and designated as "Option #2" on Exhibit A hereto. Option
#2 may be exercised at any time on or before March 31, 1998, by Lessee
delivering Lessee's Notice to Lessor. If Option #2 is exercised as aforesaid,
the lease term for Option Space #2 shall commence on the earlier to occur of (i)
the date Lessee first occupies all

                                       3
<PAGE>

or any portion of Option Space #2 for any use or purpose other than Lessee's
construction of leasehold improvements therein, (ii) the date of commencement
of such term as specified in Lessee's Notice or (iii) April 1, 1999.

     (d)  Any Option Space as to which Lessee fails to timely exercise an
Expansion Option as provided herein shall be deemed to be Primary ROFR Space (as
hereinafter defined in Section 5(a)), effective on the day after the last date
upon which such Expansion Option could be timely exercised by Lessee hereunder.
If Lessee does not exercise Option #1 on or before December 31, 1997, Option
Space #2 shall be deemed to be Primary ROFR Space effective on January 1, 1998.

     (e)  Lessee's right to exercise an Expansion Option shall be contingent
upon Lessee not being in Default under the Lease, as amended hereby, either on
the date that Lessee exercises such Expansion Option or, unless waived in
writing by Lessor for purposes of the Expansion Option, on the date that
otherwise would have been the commencement date of the lease term for the
applicable Option Space. If Lessee is not in Default under the Lease, as amended
hereby, on the date Lessee exercises such Expansion Option but is so in Default
on the date that otherwise would have been the commencement date of the lease
term for the applicable Option Space and Lessor does not waive in writing such
Default for purposes of the Expansion Option, then, notwithstanding Lessee's
timely exercise of the Expansion Option, Lessee shall have no right to lease
such Option Space as a result of Lessee's exercise of such Expansion Option.

     (f)  If Lessee exercises an Expansion Option, the following terms and
provisions shall apply:

          (i)   For purposes of this Section 4(f), "Option Space" shall mean the
     space as to which an Expansion Option has been exercised;

          (ii)  The lease term for the Option Space shall expire on the last day
     of the term of the Lease, as amended hereby;

          (iii) The annual rate of Base Rent per rentable square foot payable
     for the Option Space shall at all times during the lease term for the
     Option Space be equal to the annual rate of Base Rent per rentable square
     foot then payable for the Original Premises under the Lease, as amended by
     Section 3(a) of this Fourth Amendment. Lessee shall pay the Rent Adjustment
     for the Option Space, as provided in Section 2B of the Original Lease,
     commencing immediately upon the commencement date of the lease term for the
     Option Space, and "Lessee's Proportionate Share" as used in clause (iii) of
     Section 2A of the Original Lease shall mean the percentage determined by
     dividing the aggregate rentable area of the entire Premises (excluding the
     Additional Premises) including the Option Space by 424,052.32 rentable
     square feet. For purposes of this Section 4, the

                                       4
<PAGE>

rentable area of the Option Space shall be as determined by Lessor or, at
Lessor's option, Lessor's architect, in accordance with Lessor's then current
space measurement standards for comparable space in the Building;

     (iv)      Lessee shall not be entitled to any rental abatement for the
Option Space;


     (v)       Lessee shall accept the Option Space in an "as-is", "where-is"
physical condition from Lessor, without any agreement, representation, credit or
allowance from Lessor with respect to the improvement or condition thereof
except as set forth in this Section 4(f)(v). Lessee shall pay for any and all
costs or expenses associated with any leasehold improvement work in the Option
Space, which work shall be performed by Lessee in accordance with the terms of
Section 13 of the Original Lease, except that upon completion of such work and
Lessee's delivery of contractors affidavits and full and final waivers of lien
and receipted bills covering all labor and materials expended and used for such
work, Lessor shall pay to Lessee, as Lessor's contribution toward the payment of
the cost and expense of improving the Option Space ("Lessor's Option Space
Contribution"), a sum equal to the dollar amount per rentable square foot of the
Option Space, as set forth in the column entitled "Adjusted Allowance Per
Square Foot" on the schedule attached hereto as Exhibit C and made a part hereof
("Lessor's Contribution Schedule") corresponding to the calendar month in which
Lessee first occupies the Option Space, multiplied by the number of rentable
square feet contained in the Option Space. In the event that Lessee has
satisfied all conditions and requirements as set forth herein and in the Lease
for the payment of Lessor's Option Space Contribution and Lessor fails to pay
Lessor's Option Space Contribution to Lessee within ninety (90) days after
Lessee notifies Lessor in writing that all such conditions and requirements have
been satisfied and that such payment is due and owing to Lessee hereunder, and
further provided that Lessee is not then in breach or default under the Lease,
as amended hereby, Lessee shall, upon the expiration of said ninety (90) day
period, be entitled to offset the amount of Lessor's Option Space Contribution
from the then next due installments of Base Rent thereafter payable by Lessee
under the Lease, as amended hereby, until the full amount of Lessor's Option
Space Contribution has been paid or offset as provided herein; and

     (vi)      All of the terms and provisions of the Lease, as hereby amended,
shall apply with respect to the Option Space, except as otherwise provided in
this Section 4 or except as same may be inconsistent with the provisions of this
Section 4, and the Option Space shall be deemed to be a part of the Premises
effective as of the first day of the lease term for such Option Space.

                                       5
<PAGE>

     (g)  If Lessee exercises an Expansion Option, Lessor and Lessee shall
execute and deliver an amendment to the Lease reflecting the lease by Lessor to
Lessee of the Option Space on the terms provided above, which amendment shall be
executed and delivered promptly after Lessee delivers Lessee's Notice to Lessor.

     (h)  Each Expansion Option shall automatically terminate and become null
and void and of no force or effect upon the earlier to occur of (1) the
expiration or termination of the Lease, (2) the termination of Lessee's right to
possession of the Premises, (3) the assignment of the Lease by Lessee, in whole
or in part, which is not in accordance with Section 14 of the Original Lease, or
which is to a party (or any affiliate thereof) who is then, or was within the
preceding six (6) months, a tenant in, or otherwise an occupant of, the
Building, (4) the sublease of the Premises, or any part thereof, which is not in
accordance with Section 14 of the original Lease, or which is to a party (or any
affiliate thereof) who is then, or was within the preceding six (6) months, a
tenant in, or otherwise an occupant of, the Building, or (5) the failure of
Lessee to timely or properly exercise such Expansion Option. Without limiting
the foregoing, no Expansion Option shall be assignable by Lessee separately from
the Lease nor shall any Expansion Option be exercisable by any party other than
Lessee except for Lessee's assignee pursuant to an assignment of the Lease in
accordance with Section 14 of the Original Lease which assignee (or any
affiliate thereof) is not, at the effective date of the assignment, or was not
for the six (6) months preceding the effective date of the assignment, a tenant
in, or otherwise an occupant of, the Building.  For purposes of this Fourth
Amendment, an "affiliate" of a party or assignee shall mean any one or more
partners, principals or shareholders of any such party or assignee, or any other
person or entity which controls, is controlled by or is under common control
with such party or assignee.

     5.   RIGHT OF FIRST REFUSAL - PRIMARY ROFR SPACE.  Section 3 of the Third
Amendment is hereby deleted in its entirety and the following is substituted in
its place and stead.

     (a)  For purposes of this Lease, the term "Primary ROFR Space" shall mean
all leasable space located on the 14th floor of the Building within the area
designated as "Primary ROFR Space" on Exhibit A-1 attached hereto and made a
part hereof, excluding therefrom (i) Option Space (except as provided in Section
4(d) above) and (ii) any space leased to a third (3rd) party as of the date of
execution of this Amendment, including any subsequent renewals or extensions
thereof, until such time as such lease expires or is terminated.

     (b)  With respect to any lease for all or any portion of the Primary ROFR
Space which Lessor hereafter intends to enter into with a third (3rd) party,
Lessor shall deliver written notice of such intent to Lessee ("Lessor's Primary
ROFR Notice") prior to Lessor entering into any such lease. Lessor's Primary
ROFR Notice shall state (i) the location and rentable area of the portion of the
Primary ROFR Space which Lessor desires to lease, (ii) the proposed lease term
for such portion of the Primary ROFR Space, (iii) the date upon which such
portion of the Primary ROFR Space shall be available for occupancy, (iv) the
annual rate of Base Rent per

                                       6
<PAGE>

square foot of rentable area which Lessor desires to charge for such portion of
the Primary ROFR Space, (v) the amount of all rent adjustments which Lessor
desires to charge for such portion of the Primary ROFR Space including, without
limitation, all fixed and/or indexed adjustments to such rate and rent
adjustments for operating expenses and real estate taxes for the Building and
(vi) all of the tenant concessions (e.g., without limitation, rent abatements
and tenant improvement allowances), if any, which Lessor would be willing to
provide to lease such Primary ROFR Space (all of which concessions, other than
tenant improvement allowances, are hereinafter referred to as "Tenant
Concessions"). Lessee shall thereupon have a right of first refusal (a "Primary
ROFR Refusal Right") to lease all (but not less than all) of the portion of the
Primary ROFR Space described in said Lessor's Primary ROFR Notice, subject to
the following terms and conditions:

          (i)     Lessee shall deliver a written notice of such intent to Lessor
     exercising the Primary ROFR Refusal Right ("Lessee's Primary ROFR Exercise
     Notice") within ten (10) business days after Lessor delivers Lessor's
     Primary ROFR Notice for such Primary ROFR Refusal Right to Lessee. For
     purposes of this Fourth Amendment, "business day" shall mean any day other
     than a Saturday, a Sunday or any state or federal holiday on which the
     United States Postal Service does not make regularly scheduled delivery of
     first class mail; and

          (ii)    Lessee's right to exercise the Primary ROFR Refusal Right
     shall be contingent upon Lessee not being in Default under the Lease, as
     hereby amended, either on the date Lessee exercises such Primary ROFR
     Refusal Right or, unless waived in writing by Lessor for purposes of such
     Primary ROFR Refusal Right, on the availability date specified in the
     applicable Lessor's Primary ROFR Notice for such portion of the Primary
     ROFR Space. If Lessee is not in Default under the Lease, as amended hereby,
     on the date Lessee exercises such Primary ROFR Refusal Right but is so in
     Default on the availability date specified in the applicable Lessor's
     Primary ROFR Notice and Lessor does not waive in writing such Default for
     purposes of such Primary ROFR Refusal Right, then, notwithstanding Lessee's
     exercise of such Primary ROFR Refusal Right, Lessee shall have no right to
     lease the Primary ROFR Space as a result of Lessee's exercise of such
     Primary ROFR Right.

In the event that Lessee does not timely or properly exercise a Primary ROFR
Refusal Right, Lessor may at any time thereafter lease the applicable portion of
the Primary ROFR Space to any third (3rd) party tenant on substantially the same
economic terms as set forth in Lessor's Primary ROFR Notice applicable thereto
without any further rights of Lessee to lease such space, provided that Lessee's
failure to timely or properly exercise such Primary ROFR Refusal Right shall
not act as a waiver of or otherwise affect the Expansion Options granted to
Lessee pursuant to Section 4 hereof nor act as a waiver of or otherwise affect
any Primary ROFR Refusal Right as to any other portion of the Primary ROFR
Space, any Secondary ROFR Refusal

                                       7
<PAGE>

Right (as hereinafter defined) or any ROFR Space #3 Refusal Right (as
hereinafter defined) and further provided that in the event that Lessor
thereafter intends to enter into a lease with a third (3rd) party for the
applicable portion of the Primary ROFR Space upon economic terms materially more
favorable to such tenant than those set forth in the most recent Lessor's
Primary ROFR Notice applicable thereto, such Primary ROFR Space shall again
become subject to Lessee's Primary ROFR Refusal Right as set forth in this
Section 5.

     (c)    If Lessee exercises a Primary ROFR Refusal Right, the following
terms and provisions shall apply:

            (i)    Notwithstanding the location of any Primary ROFR Space for
     which a Primary ROFR Refusal Right has been exercised as heretofore
     provided in this Section, in the event Lessee exercises a Primary ROFR
     Refusal Right as aforesaid, the Primary ROFR Space actually to be leased to
     Lessee shall consist of the space within the area comprising the Primary
     ROFR Space and any Option Space which is subject to an unexercised
     Expansion Option which is located closest to the west end of the Building
     and is not then leased to a third (3rd) party, under option to be leased to
     a third (3rd) party, subject to a right of first refusal to a third (3rd)
     party or otherwise committed to be leased or occupied by a third (3rd)
     party (the "Available Primary ROFR Space"). In the event any Primary ROFR
     Space is relocated as aforesaid, then (1) Landlord shall have the right, in
     its sole discretion and upon notice to Lessee, to increase or decrease the
     size of such relocated Primary ROFR Space by an amount not to exceed ten
     percent (10%) of the rentable area thereof as set forth in Lessor's Primary
     ROFR Notice, to the reasonably minimal extent necessary to accommodate the
     actual configuration of the Available Primary ROFR Space and Lessor's then
     current space demising and measurement standards for comparable space in
     the Building, in which event all terms contained in Lessor's Primary ROFR
     Notice for such Primary ROFR Space (including, without limitation, any
     Tenant Concessions) and the rent payable therefor shall be deemed
     automatically adjusted pro rata to such increase or decrease and (2) any
     Option Space which remains subject to a valid and existing but unexercised
     Expansion Option shall be automatically relocated to the next most westerly
     Available Primary ROFR Space which is contiguous to the relocated Primary
     ROFR Space in which event Landlord shall have the right, in its sole
     discretion and upon notice to Lessee, to increase or decrease the size of
     such relocated Option Space by an amount not to exceed ten percent (10%) of
     the rentable area thereof prior to such relocation, to the reasonably
     minimal extent necessary to accommodate the actual configuration of the
     Available Primary ROFR Space and Lessor's then current space demising and
     measurement standards for comparable space in the Building;

                                       8
<PAGE>

     (ii)    The lease term for such Primary ROFR Space shall commence on the
availability date specified in the applicable Lessor's Primary ROFR Notice and
shall expire on the last day of the term of the Lease, as amended hereby;

     (iii)   The Base Rent and rental adjustments payable for such Primary ROFR
Space shall be as set forth in the applicable Lessor's Primary ROFR Notice (as
the same may be adjusted in the manner provided in Section 5(c)(i) above) and
Lessee shall be entitled to receive, with respect to such Primary ROFR Space,
any and all Tenant Concessions set forth in such Notice (as the same may be
adjusted in the manner provided in Section 5(c)(i) above), except that the
amount of each such Tenant Concession shall be further adjusted by multiplying
such amount by a fraction (the "Primary ROFR Term Adjustment") whose numerator
is the number of calendar months in the period commencing with the calendar
month in which Lessee first occupies such Primary ROFR Space and continuing to
and including the calendar month in which the Expiration Date occurs, and whose
denominator is the number of calendar months contained in the proposed lease
term as set forth in such Lessor's Primary ROFR Notice;

     (iv)    For purposes of paying the rental adjustments set forth in Section
5(c)(iii) above with respect to any Primary ROFR Space actually leased by
Lessee, Lessee's Proportionate Share shall be increased effective as of the
commencement date of the lease term for such Primary ROFR Space by adding to
such then effective Lessee's Proportionate Share the percentage determined by
dividing the rentable area of such Primary ROFR Space by 424,052.32 rentable
square feet. For purposes of this Section 5, the rentable area of any Primary
ROFR Space actually leased by Lessee (whether or not relocated) shall be as
determined by Lessor or, at Lessor's option, Lessor's architect, in accordance
with Lessor's then current space measurement standards for comparable space in
the Building;

     (v)     Lessee shall not be entitled to any rental abatement for any
portion of the Primary ROFR Space except as provided in Section 5(c)(iii) above;

     (vi)    Lessee shall accept the applicable portion of the Primary ROFR
Space in an "as-is", "where-is" physical condition from Lessor, without any
agreement, representation, credit or allowance from Lessor with respect to the
improvement or condition thereof except as set forth in this Section 5(c)(vi).
Lessee shall pay for any and all costs or expenses associated with any leasehold
improvement work in such Primary ROFR Space, which work shall be performed by
Lessee in accordance with the terms of Section 13 of the Original Lease, except
that upon completion of such work and Lessee's delivery of contractors
affidavits and full and final waivers of lien and receipted bills covering all
labor and materials expended and used for such work, Lessor shall pay to Lessee,
as

                                       9
<PAGE>

     Lessor's contribution toward the payment of the cost and expense of
     improving such Primary ROFR Space ("Lessor's Primary ROFR Space
     Contribution"), a sum equal to the dollar amount of tenant improvement
     allowance per rentable square foot of the original Primary ROFR Space, as
     set forth in the applicable Lessor's Primary ROFR Notice, multiplied by the
     number of rentable square feet contained in the Primary ROFR Space which is
     actually leased to Lessee, and, and further multiplied by the Primary ROFR
     Term Adjustment. In the event that Lessee has satisfied all conditions and
     requirements as set forth herein and in the Lease for the payment of
     Lessor's Primary ROFR Space Contribution and Lessor fails to pay in full
     Lessor's Primary ROFR Space Contribution to Lessee within ninety (90) days
     after Lessee notifies Lessor in writing that all such conditions and
     requirements have been satisfied and that such payment is due and owing to
     Lessee hereunder, and further provided that Lessee is not then in breach or
     default under the Lease, as amended hereby, Lessee shall, upon the
     expiration of said ninety (90) day period, be entitled to offset the unpaid
     amount of Lessor's Primary ROFR Space Contribution from the then next due
     installments of Base Rent thereafter payable by Lessee under the Lease, as
     amended hereby, until the full amount of Lessor's Primary ROFR Space
     Contribution has been paid or offset as provided herein; and

          (vii) All of the terms and provisions of the Lease, as hereby amended,
     shall apply with respect to the applicable portion of the Primary ROFR
     Space, except as otherwise provided in this Section 5 or except as same may
     be inconsistent with the provisions of this Section 5, and such portion of
     the Primary ROFR Space shall be deemed to be a part of the Premises
     effective as of the first day of the lease term for such space.

     (d)    If Lessee exercises a Primary ROFR Refusal Right, Lessor and Lessee
shall execute and deliver an amendment of the Lease reflecting the lease of the
applicable portion of the Primary ROFR Space by Lessor to Lessee on the terms
and provisions set forth in this Section 5, which amendment shall be executed
and delivered within thirty (30) days after Lessee exercises the Primary ROFR
Refusal Right.

     (e)    The Primary ROFR Refusal Right shall automatically terminate and
become null and void upon the earlier to occur of (1) the expiration or
termination of the Lease, (2) the termination of Lessee's right to possession of
the Premises, (3) the assignment of the Lease by Lessee, in whole or in part,
which is not in accordance with Section 14 of the Original Lease, or which is to
a party (or any affiliate thereof) who is then, or was within the preceding six
(6) months, a tenant in, or otherwise an occupant of, the Building, (4) the
sublease by Lessee of the Premises, or any part thereof, which is not in
accordance with Section 14 of the Original Lease, or which is to a party (or an
affiliate thereof) who is then, or was within the preceding six (6) months, a
tenant in, or otherwise an occupant of, the Building, or (5) the failure of
Lessee to timely or properly exercise a primary ROFR Refusal Right. Without
limiting the foregoing, no

                                      10
<PAGE>

Primary ROFR Refusal Right shall be assignable by Lessee separately from the
Lease nor shall any Primary ROFR Refusal Right be exercisable by any party
other than Lessee except for Lessee's assignee pursuant to an assignment of the
Lease in accordance with Section 14 of the Original Lease which assignee (or any
affiliate thereof) is not, at the effective date of the assignment, or was not
for the six (6) months preceding the effective date of the assignment, a tenant
in, or otherwise an occupant of, the Building.

     6.   RIGHT OF FIRST REFUSAL - SECONDARY ROFR SPACE.
          ---------------------------------------------

     (a)  For purposes of this Lease, the term "Secondary ROFR Space" shall mean
all leasable space located on the fourteenth (14th) floor of the Building within
the area designated as "Secondary ROFR Space" on Exhibit A-1 attached hereto and
made a part hereof, excluding therefrom (i) the space denoted as "ROFR #3" on
Exhibit A attached hereto and (ii) any space leased to a third (3rd) party as of
the date of execution of this Amendment, including any subsequent renewals or
extensions thereof, until such time as such lease expires or is terminated.

     (b)  With respect to any lease for all or any portion of the Secondary ROFR
Space which Lessor hereafter intends to enter into with a third (3rd) party,
Lessor shall deliver written notice of such intent to Lessee ("Lessor's
Secondary ROFR Notice") prior to Lessor entering into any such lease. Lessor's
Secondary ROFR Notice shall state (i) the location and rentable area of the
portion of the Secondary ROFR Space which Lessor desires to lease, (ii) the
proposed lease term for such portion of the Secondary ROFR Space, (iii) the date
upon which such portion of the Secondary ROFR Space shall be available for
occupancy, (iv) the annual rate of Base Rent per square foot of rentable area
which Lessor desires to charge for such portion of the Secondary ROFR Space, (v)
the amount of all rent adjustments which Lessor desires to charge for such
portion of the Secondary ROFR Space including, without limitation, all fixed
and/or indexed adjustments to such rate and rent adjustments for operating
expenses and real estate taxes for the Building and (vi) the tenant improvement
allowances and Tenant Concessions, if any, which Lessor would be willing to
provide to lease such Secondary ROFR Space. Lessee shall thereupon have a right
of first refusal (a "Secondary ROFR Refusal Right") to lease all (but not less
than all) of the portion of the Secondary ROFR Space described in said Lessor's
Secondary ROFR Notice, subject to the following terms and conditions:

          (i)  Lessee shall deliver a written notice of such intent to Lessor
     exercising the Secondary ROFR Refusal Right ("Lessee's Secondary ROFR
     Exercise Notice") within ten (10) business days after Lessor delivers
     Lessor's Secondary ROFR Notice for such Secondary ROFR Refusal Right to
     Lessee; and

          (ii) Lessee's right to exercise the Secondary ROFR Refusal Right shall
     be contingent upon Lessee not being in Default under the Lease, as hereby
     amended, either on the date Lessee exercises such Secondary ROFR Refusal
     Right or, unless waived in writing by Lessor for purposes of such Secondary
     ROFR Refusal Right, on the availability date specified in the applicable
     Lessor's

                                      11

<PAGE>

     Secondary ROFR Notice for such portion of the Secondary ROFR Space. If
     Lessee is not in Default under the Lease, as amended hereby, on the date
     Lessee exercises such Secondary ROFR Refusal Right but is so in Default on
     the availability date specified in the applicable Lessor's Secondary ROFR
     Notice and Lessor does not waive in writing such Default for purposes of
     such Secondary ROFR Right, then, notwithstanding Lessee's exercise of such
     Secondary ROFR Right, Lessee shall have no right to lease the Secondary
     ROFR Space as a result of Lessee's exercise of such Secondary ROFR Refusal
     Right.

In the event that Lessee does not timely or properly exercise a Secondary ROFR
Refusal Right, Lessor may at any time thereafter lease the applicable portion
of the Secondary ROFR Space to any third (3rd) party tenant on substantially the
same economic terms as set forth in Lessor's Secondary ROFR Notice applicable
thereto without any further rights of Lessee to lease such space, provided that
Lessee's failure to timely or properly exercise such Secondary ROFR Refusal
Right shall not act as a waiver of or otherwise affect the Expansion Options
granted to Lessee pursuant to Section 4 hereof nor act as a waiver of or
otherwise affect any Secondary ROFR Refusal Right as to any other portion of the
Secondary ROFR Space, any Primary ROFR Refusal Right or any ROFR Space #3
Refusal Right and further provided that in the event that Lessor thereafter
intends to enter into a lease with a third (3rd) party for the applicable
portion of the Secondary ROFR Space upon economic terms materially more
favorable to such tenant than those set forth in the most recent Lessor's
Secondary ROFR Notice applicable thereto, such Secondary ROFR Space shall again
become subject to Lessee's Secondary ROFR Refusal Right as set forth in this
Section 6.

     (c)  If Lessee exercises a Secondary ROFR Refusal Right, the following
terms and provisions shall apply:

          (i)  The lease term for such Secondary ROFR Space shall commence on
     the availability date specified in the applicable Lessor's Secondary ROFR
     Notice and shall expire on the last day of the term of the Lease, as
     amended hereby;

          (ii) The Base Rent and rental adjustments payable for such Secondary
     ROFR Space shall be as set forth in the applicable Lessor's Secondary ROFR
     Notice and Lessee shall be entitled to receive, with respect to such
     Secondary ROFR Space, any and all Tenant Concessions set forth in such
     notice, except that the amount of each such Tenant Concession shall be
     adjusted by multiplying such amount by a fraction (the "Secondary ROFR Term
     Adjustment") whose numerator is the number of calendar months in the period
     commencing in the calendar month in which Lessee first occupies such
     Secondary ROFR Space and continuing to and including the calendar month in
     which the Expiration Date occurs, and whose denominator is the number of
     calendar months contained in the proposed lease term as set forth in such
     Lessor's Secondary ROFR Notice;

                                      12

<PAGE>

          (iii) For purposes of paying the rental adjustments set forth in
     Section 6(c)(ii) above with respect to such Secondary ROFR Space, Lessee's
     Proportionate Share shall be increased effective as of the commencement
     date of the lease term for such Secondary ROFR Space by adding to such then
     effective Lessee's Proportionate Share the percentage determined by
     dividing the rentable area of such Secondary ROFR Space by 424,052.32
     rentable square feet. For purposes of this Section 6, the rentable area of
     any Secondary ROFR Space actually leased by Lessee shall be as determined
     by Lessor or, at Lessor's option, Lessor's architect, in accordance with
     Lessor's then current space measurement standards for comparable space in
     the Building;

          (iv)  Lessee shall not be entitled to any rental abatement for any
     portion of the Secondary ROFR Space except as provided in Section 6(c)(ii)
     above;

          (v)   Lessee shall accept the applicable portion of the Secondary ROFR
     Space in an "as-is", "where-is" physical condition from Lessor, without any
     agreement, representation, credit or allowance from Lessor with respect to
     the improvement or condition thereof except as otherwise set forth in the
     applicable Lessor's Secondary ROFR Notice adjusted by multiplying such
     amount by the Secondary ROFR Term Adjustment ("Lessor's Secondary ROFR
     Space Contribution"). Lessee shall pay for any and all costs or expenses
     associated with any leasehold improvement work in such Secondary ROFR
     Space, which work shall be performed by Lessee in accordance with the terms
     of Section 13 of the Original Lease, except that upon completion of such
     work and Lessee's delivery of contractors affidavits and full and final
     waivers of lien and receipted bills covering all labor and materials
     expended and used for such work, Lessor shall pay to Lessee, as Lessor's
     contribution toward the payment of the cost and expense of improving such
     Secondary ROFR Space, the amount of Lessor's Secondary ROFR Space
     Contribution, if any. In the event that Lessee has satisfied all conditions
     and requirements as set forth herein and in the Lease for the payment of
     Lessor's Secondary ROFR Space Contribution, if any, and Lessor fails to pay
     in full Lessor's Secondary ROFR Space Contribution to Lessee within ninety
     (90) days after Lessee notifies Lessor in writing that all such conditions
     and requirements have been satisfied and that such payment is due and owing
     to Lessee hereunder, and further provided that Lessee is not then in breach
     or default under the Lease, as amended hereby, Lessee shall, upon the
     expiration of said ninety (90) day period, be entitled to offset the unpaid
     amount of Lessor's Secondary ROFR Space Contribution from the then next due
     installments of Base Rent thereafter payable by Lessee under the Lease, as
     amended hereby, until the full amount of Lessor's Secondary ROFR Space
     Contribution has been paid or offset as provided herein; and

                                      13
<PAGE>

          (vi) All of the terms and provisions of the Lease, as hereby amended,
     shall apply with respect to the applicable portion of the Secondary ROFR
     Space, except as otherwise provided in this Section 6 or except as same may
     be inconsistent with the provisions of this Section 6, and such portion of
     the Secondary ROFR Space shall be deemed to be a part of the Premises
     effective as of the first day of the lease term for such space.

     (d)  If Lessee exercises a Secondary ROFR Refusal Right, Lessor and Lessee
shall execute and deliver an amendment of the Lease reflecting the lease of the
applicable portion of the Secondary ROFR Space by Lessor to Lessee on the terms
and provisions set forth in this Section 6, which amendment shall be executed
and delivered within thirty (30) days after Lessee exercises the Secondary ROFR
Refusal Right.

     (e)  The Secondary ROFR Refusal Right shall automatically terminate and
become null and void upon the earlier to occur of (1) the expiration or
termination of the Lease, (2) the termination of Lessee's right to possession
of the Premises, (3) the assignment of the Lease by Lessee, in whole or in
part, which is not in accordance with Section 14 of the Original Lease, or which
is to a party (or any affiliate thereof) who is then, or was within the
preceding six (6) months, a tenant in, or otherwise an occupant of, the
Building, (4) the sublease by Lessee of the Premises, or any part thereof, which
is not in accordance with Section 14 of the Original Lease, or which is to a
party (or any affiliate thereof) who is then, or was within the preceding six
(6) months, a tenant in, or otherwise an occupant of, the Building, or (5) the
failure of Lessee to timely or properly exercise a Secondary ROFR Refusal Right.
Without limiting the foregoing, no Secondary ROFR Refusal Right shall be
assignable by Lessee separately from the Lease nor shall any Secondary ROFR
Refusal Right be exercisable by any party other than Lessee except for Lessee's
assignee pursuant to an assignment of the Lease in accordance with Section 14 of
the Original Lease which assignee (or any affiliate thereof) is not, at the
effective date of the assignment, or was not for the six (6) months preceding
the effective date of the assignment, a tenant in, or otherwise an occupant of,
the Building.

     7.   RIGHT OF FIRST REFUSAL - ROFR SPACE #3.
          --------------------------------------

     (a)  For purposes of this Lease, the term "ROFR Space #3" shall mean that
portion of the space denoted as "ROFR #3" on Exhibit A attached hereto, if any,
that has not been leased to a third (3rd) party on or before December 31, 1997.
This Amendment does not grant to Lessee any rights of first refusal to lease (i)
all or any portion of the space so denoted as "ROFR Space #3" on said Exhibit A
prior to January 1, 1998, or (ii) all or any portion of such space which is
subject to a lease to a third (3rd) party as of December 31, 1997.

     (b)  Commencing effective January 1, 1998, with respect to any lease for
all or any portion of ROFR Space #3 which Lessor hereafter intends to enter into
with a third (3rd) party, Lessor shall deliver written notice of such intent to
Lessee ("Lessor's ROFR Space #3 Notice") prior to Lessor entering into any such
lease. Lessor's ROFR Space #3 Notice shall state (i) the

                                      14

<PAGE>

location and rentable area of the portion of ROFR Space #3 which Lessor desires
to lease, (ii) the proposed lease term for such portion of ROFR Space #3, (iii)
the date upon which such portion of ROFR Space #3 shall be available for
occupancy, (iv) the annual rate of Base Rent per square foot of rentable area
which Lessor desires to charge for such portion of ROFR Space #3, (v) the amount
of all rent adjustments which Lessor desires to charge for such portion of ROFR
Space #3 including, without limitation, all fixed and/or indexed adjustments to
such rate and rent adjustments for operating expenses and real estate taxes for
the Building and (vi) the tenant improvement allowances and Tenant Concessions,
if any, which Lessor would be willing to provide to lease such portion of ROFR
Space #3. Lessee shall thereupon have a right of first refusal (a "ROFR Space #3
Refusal Right") to lease all (but not less than all) of the portion of ROFR
Space #3 described in said Lessor's ROFR Space #3 Notice, subject to the
following terms and conditions:

          (i)  Lessee shall deliver a written notice of such intent to Lessor
     exercising the ROFR Space #3 Refusal Right ("Lessee's ROFR Space #3
     Exercise Notice") within ten (10) business days after Lessor delivers
     Lessor's ROFR Space #3 Notice for such ROFR Space #3 Refusal Right to
     Lessee; and

          (ii) Lessee's right to exercise the ROFR Space #3 Refusal Right shall
     be contingent upon Lessee not being in Default under the Lease, as hereby
     amended, either on the date Lessee exercises such ROFR Space #3 Refusal
     Right or, unless waived in writing by Lessor for purposes of such ROFR
     Space #3 Refusal Right, on the availability date specified in the
     applicable Lessor's ROFR Space #3 Notice for such portion of ROFR Space #3.
     If Lessee is not in Default under the Lease, as amended hereby, on the date
     Lessee exercises such ROFR Space #3 Refusal Right but is so in Default on
     the availability date specified in the applicable Lessor's ROFR Space #3
     Notice and Lessor does not waive in writing such Default for purposes of
     such ROFR Space #3 Refusal Right, then, notwithstanding Lessee's exercise
     of such ROFR Space #3 Refusal Right, Lessee shall have no right to lease
     the ROFR Space #3 as a result of Lessee's exercise of such ROFR Space #3
     Refusal Right.

In the event that Lessee does not timely or properly exercise a ROFR Space #3
Refusal Right, Lessor may at any time thereafter lease the applicable portion
of ROFR Space #3 to any third (3rd) party tenant on substantially the same
economic terms as set forth in Lessor's ROFR Space #3 Notice applicable thereto
without any further rights of Lessee to lease such space, provided that Lessee's
failure to timely or properly exercise such ROFR Space #3 Refusal Right shall
not act as a waiver of or otherwise affect the Expansion Options granted to
Lessee pursuant to Section 4 hereof nor act as a waiver of or otherwise affect
any ROFR Space #3 Refusal Right as to any other portion of ROFR Space #3, any
Primary ROFR Refusal Right or any Secondary ROFR Refusal Right and further
provided that in the event that Lessor thereafter intends to enter into a lease
with a third (3rd) party for the applicable portion of ROFR Space #3 upon
economic terms materially more favorable to such tenant than those set forth in
the most recent Lessor's

                                      15

<PAGE>

ROFR Space #3 Notice applicable thereto, such ROFR Space shall again become
subject to Lessee's ROFR Space #3 Refusal Right as set forth in this Section 7.

     (c)  If Lessee exercises a ROFR Space #3 Refusal Right, then at Lessee's
option, exercised by notice to Lessor contained in Lessee's ROFR Space #3
Exercise Notice with respect to ROFR Space #3, the space actually to be leased
to Lessee pursuant to Lessee's exercise of its ROFR Space #3 Refusal Right shall
be relocated to Available Primary ROFR Space (as defined in Section 5(c)(i)
above) located closest to the west end of the Building.

     (d)  If Lessee's exercises a ROFR Space #3 Refusal Right and elects, as
provided in Section 7(c) above, that the space actually to be leased to Lessee
pursuant to Lessee's exercise of its ROFR #3 Refusal Right shall consist of the
Available Primary ROFR Space located closest to the west end of the Building,
then, in such event, the following terms and provisions shall apply:

          (i)  Lessee's ROFR Space #3 Refusal Right as to the actual ROFR Space
     #3 itself, on the terms stated in the applicable Lessor's ROFR Space #3
     Notice, shall be deemed waived and Lessor may at any time thereafter lease
     all or any portion of ROFR Space #3 to any third (3rd) party tenant on
     substantially the same economic terms as set forth in such Lessor's ROFR
     Space #3 Notice without any further rights of Lessee to lease ROFR Space
     #3, provided that in the event that Lessor thereafter intends to enter into
     a lease with a third (3rd) party tenant for all or any portion of ROFR
     Space #3 upon economic terms materially more favorable to such tenant than
     those set forth in such Lessor's ROFR Space #3 Notice, ROFR Space #3 shall
     again become subject to Lessee's ROFR Space #3 Refusal Right as set forth
     in this Section 7;

          (ii)  Lessor shall have the right, in its sole discretion and upon
     notice to Lessee, to increase or decrease the size of such relocated ROFR
     Space #3 by an amount not to exceed ten percent (10%) of the rentable area
     thereof as set forth in Lessor's ROFR Space #3 Notice, to the reasonably
     minimal extent necessary to accommodate the actual configuration of the
     Available Primary ROFR Space and Lessor's then current space demising
     standards for comparable space in the Building, in which event all terms
     contained in Lessor's ROFR Space #3 Notice (including, without limitation,
     any Tenant Concessions) and the rent payable therefor shall be deemed
     automatically adjusted pro rata to such increase or decrease (except that
     Lessor's contribution toward the cost and expense of improving such
     relocated ROFR Space #3 shall be determined in accordance with Section
     7(d)(vii) below) and any Option Space which remains subject to a valid and
     existing but unexercised Expansion Option shall be automatically relocated
     to the next most westerly Available Primary ROFR Space which is contiguous
     to the relocated ROFR Space #3. In the event that any Option Space is
     relocated as aforesaid, then Lessor shall have the right, in its sole
     discretion and upon


                                      16

<PAGE>

     notice to Lessee, to increase or decrease the size of such relocated Option
     Space by an amount not to exceed ten percent (10%) of the rentable area
     thereof, to the reasonably minimal extent necessary to accommodate the
     actual configuration of the Available Primary ROFR Space and Lessor's then
     current space demising and measurement standards for comparable space in
     the Building;

          (iii)  The lease term for such applicable portion of ROFR Space #3 (as
     relocated to Primary ROFR Space) shall commence on the availability date
     specified in the applicable Lessor's ROFR Space #3 Notice and shall expire
     on the last day of the term of the Lease, as hereby amended;

          (iv)  The Base Rent and rental adjustments payable for such Primary
     ROFR Space shall be determined by Lessor in its sole discretion to be at
     rates equal to either (A) the Base Rent and rental adjustments payable for
     ROFR Space #3 as set forth in the applicable Lessor's ROFR Space #3 Notice
     or (B) the Base Rent and rental adjustments payable under the Lease for the
     Original Premises for the corresponding portion of the Term. In the case
     where the Base Rent and rental adjustments payable for such Primary ROFR
     Space are determined to be as set forth in the applicable Lessor's ROFR
     Space #3 Notice as provided in clause (A) above, Lessee shall be entitled
     to receive, with respect to such Primary ROFR Space, any and all Tenant
     Concessions set forth in such Lessor's ROFR Space #3 Notice, except that
     the amount of each such Tenant Concession shall be adjusted to a sum equal
     to the dollar amount of such Tenant Concession per rentable square foot of
     ROFR Space #3, as set forth in such Lessor's ROFR Space #3 Notice,
     multiplied by the number of rentable square feet contained in such Primary
     ROFR Space, and further multiplied by a fraction (the "ROFR Space #3 Term
     Adjustment") whose numerator is the number of calendar months in the period
     commencing with the calendar month in which Lessee first occupies such
     Primary ROFR Space and continuing to and including the calendar month in
     which the Expiration Date of Term of the Lease, as amended hereby, occurs,
     and whose denominator is the number of calendar months contained in the
     proposed lease term as set forth in such Lessor's ROFR Space #3 Notice. In
     the case where Base Rent and rental adjustments payable for such Primary
     ROFR Space are determined to be as payable under the Lease for the Original
     Premises for the corresponding portion of the Term as provided in clause
     (B) above, Lessee shall not be entitled to receive any Tenant Concessions
     including, without limitation, any Tenant Concessions set forth in such
     Lessor's ROFR Space #3 Notice;

          (v)  For purposes of paying the rental adjustments set forth in
     Section 7(d)(iv) above as to any ROFR Space actually leased by Lessee
     pursuant to this Section 7(d), Lessee's Proportionate Share shall be
     increased effective as of the commencement date of the lease term for such
     ROFR Space by adding to such


                                      17

<PAGE>

     then effective Lessee's Proportionate Share the percentage determined by
     dividing the rentable area of such ROFR Space by 424,052.32 rentable square
     feet. For purposes of this Section 7(d), the rentable area of any ROFR
     Space actually leased by Lessee shall be as determined by Lessor or, at
     Lessor's option, Lessor's architect, in accordance with Lessor's then
     current space measurement standards for comparable space in the Building;

          (vi)  Lessee shall not be entitled to any rental abatement for any
     portion of the relocated ROFR Space #3 except in the case where the Base
     Rent and rental adjustments payable for such relocated ROFR Space #3 are to
     be the same as set forth in the applicable Lessor's ROFR Space #3 Notice
     pursuant to Section 7(d)(iv)(A) above in which event Lessee shall be
     entitled to the rental abatement, if any, set forth in such Lessor's ROFR
     Space #3 Notice;

          (vii)  Lessee shall accept the applicable portion of ROFR Space #3, as
     relocated, in an "as-is", "where-is" physical condition from Lessor,
     without any agreement, representation, credit or allowance from Lessor with
     respect to the improvement or condition thereof, except as set forth below
     in this Section 7(d)(vii). Lessee shall pay for any and all costs or
     expenses associated with any leasehold improvement work in such ROFR Space
     which shall be performed by Lessee in accordance with the terms of Section
     13 of the Original Lease and upon completion of such work and Lessee's
     delivery of contractors affidavits and full and final waivers of lien and
     receipted bills covering all labor and materials expended and used for such
     work, Lessor shall pay to Lessee, as Lessor's contribution toward the
     payment of the cost and expense of improving such ROFR Space ("Lessor's
     ROFR Space #3 Contribution"), an amount which shall be determined as
     follows:

               A.  in the case where the Base Rent and rental adjustments
          payable for such Primary ROFR Space pursuant to Section 7(d)(iv)(A)
          above are to be the same as set forth in the applicable Lessor's ROFR
          Space #3 Notice, Lessor's ROFR Space #3 Contribution shall be a sum
          equal to the dollar amount of tenant improvement allowance per
          rentable square foot of ROFR Space #3, as set forth in such Lessor's
          ROFR Space #3 Notice, multiplied by the number of rentable square feet
          contained in such Primary ROFR Space, and further multiplied by the
          ROFR Space #3 Term Adjustment; or

               B.  in the case where the Base Rent and rental adjustments
          payable for such Primary ROFR Space pursuant to Section 7(d)(iv)(B)
          above are to be the same as for the Original Premises for the
          corresponding portion of the Term, Lessor's ROFR Space #3 Contribution
          shall be a sum equal to the dollar amount per rentable square foot of
          such


                                      18

<PAGE>

          Primary ROFR Space, as set forth in the column entitled "Adjusted
          Allowance Per Square Foot" on Lessor's Contribution Schedule
          corresponding to the calendar month in which Lessee first occupies
          such Primary ROFR Space, multiplied by the number of rentable square
          feet contained in such Primary ROFR Space; or

     In the event that Lessee has satisfied all conditions and requirements as
     set forth herein and in the Lease for the payment of Lessor's ROFR Space #3
     Contribution and Lessor fails to pay in full Lessor's ROFR Space #3
     Contribution to Lessee within ninety (90) days after Lessee notifies Lessor
     in writing that all such conditions and requirements have been satisfied
     and that such payment is due and owing to Lessee hereunder, and further
     provided that Lessee is not then in breach or default under the Lease, as
     amended hereby, Lessee shall, upon the expiration of said ninety (90) day
     period, be entitled to offset the unpaid amount of Lessor's ROFR Space #3
     Contribution from the then next due installments of Base Rent thereafter
     payable by Lessee under the Lease, as amended hereby, until the full amount
     of Lessor's ROFR Space #3 Contribution has been paid or offset as provided
     herein; and

          (viii)  All of the terms and provisions of the Lease, as amended
     hereby, shall apply with respect to the applicable portion of ROFR Space
     #3, except as otherwise provided in this Section 7 or except as same may be
     inconsistent with the provisions of this Section 7, and such portion of
     ROFR Space #3 shall be deemed to be a part of the Premises effective as of
     the first day of the lease term for such space.

     (e)  If Lessee exercises a ROFR Space #3 Refusal Right and Lessee does not
elect, as provided in Section 7(c) above, that the space actually to be leased
to Lessee pursuant to Lessee's exercise of its ROFR Space #3 Refusal Right shall
consist of the Available Primary ROFR Space located closest to the west end of
the Building, then, in such event, the following terms and provisions shall
apply:

          (i)  The lease term for such applicable portion of ROFR Space #3 shall
     commence on the availability date specified in the applicable Lessor's ROFR
     Space #3 Notice and shall expire on the last day of the term of the Lease,
     as amended hereby;

          (ii)  The Base Rent and rental adjustments payable for the applicable
     portion of ROFR Space #3 shall be equal to the Base Rent and rental
     adjustments payable for ROFR Space #3 as set forth in the applicable
     Lessor's ROFR Space #3 Notice and Lessee shall be entitled to receive, with
     respect to such portion of ROFR Space #3, any and all Tenant Concessions
     set forth in such Lessor's ROFR Space #3 Notice except that the amount of
     each such Tenant Concession shall be


                                      19

<PAGE>

     adjusted by a sum equal to the dollar amount of such Tenant Concession set
     forth in such Lessor's ROFR Space #3 Notice multiplied by the ROFR Space #3
     Term Adjustment (as defined in Section 7(d)(iv) above);

          (iii)  For purposes of paying the rental adjustments set forth in
     Section 7(e)(ii) above with respect to any ROFR Space actually leased by
     Lessee pursuant to this Section 7(e), Lessee's Proportionate Share shall be
     increased effective as of the commencement date of the lease term for such
     ROFR Space by adding to such then effective Lessee's Proportionate Share
     the percentage determined by dividing the rentable area of such ROFR Space
     by 424,052.32 rentable square feet. For purposes of this Section 7(e), the
     rentable area of any ROFR Space actually leased by Lessee shall be as
     determined by Lessor or, at Lessor's option, Lessor's architect, in
     accordance with Lessor's then current space measurement standards for
     comparable space in the Building;

          (iv)  Lessee shall not be entitled to any rental abatement for any
     portion of ROFR Space #3 except as otherwise set forth in the applicable
     Lessor's ROFR Space #3 Notice;

          (v)  Lessee shall accept the applicable portion of ROFR Space #3 in an
     "as-is", "where-is" physical condition from Lessor, without any agreement,
     representation, credit or allowance from Lessor with respect to the
     improvement or condition thereof, except as otherwise set forth in the
     applicable Lessor's ROFR Space #3 Notice. Lessee shall pay for any and all
     costs or expenses associated with any leasehold improvement work in such
     ROFR Space which shall be performed by Lessee in accordance with the terms
     of Section 13 of the Original Lease and upon completion of such work and
     Lessee's delivery of contractors affidavits and full and final waivers of
     lien and receipted bills covering all labor and materials expended and used
     for such work, Lessor shall pay to Lessee, as Lessor's contribution toward
     the payment of the cost and expense of improving such ROFR Space ("Lessor's
     ROFR Space #3 Contribution"), a sum equal to the dollar amount of tenant
     improvement allowance per rentable square foot of ROFR Space #3, as set
     forth in the applicable Lessor's ROFR Space #3 Notice, multiplied by the
     number of rentable square feet contained in such ROFR Space #3, and further
     multiplied by the ROFR Space #3 Term Adjustment. In the event that Lessee
     has satisfied all conditions and requirements as set forth herein and in
     the Lease for the payment of Lessor's ROFR Space #3 Contribution and Lessor
     fails to pay in full Lessor's ROFR Space #3 Contribution to Lessee within
     ninety (90) days after Lessee notifies Lessor in writing that all such
     conditions and requirements have been satisfied and that such payment is
     due and owing to Lessee hereunder, and further provided that Lessee is not
     then in breach or default under the Lease, as amended hereby, Lessee shall,
     upon the expiration of said ninety (90) day period, be


                                      20

<PAGE>

     entitled to offset the unpaid amount of Lessor's ROFR Space #3 Contribution
     from the then next due installments of Base Rent thereafter payable by
     Lessee under the Lease, as amended hereby, until the full amount of
     Lessor's ROFR Space #3 Contribution has been paid or offset as provided
     herein; and

           (vi) All of the terms and provisions of the Lease, as amended hereby,
     shall apply with respect to the applicable portion of ROFR Space #3, except
     as otherwise provided in this Section 7 or except as same may be
     inconsistent with the provisions of this Section 7, and such portion of
     ROFR Space #3 shall be deemed to be a part of the Premises effective as of
     the first day of the lease term for such space.

     (f) If Lessee exercises a ROFR Space #3 Refusal Right, Lessor and Lessee
shall execute and deliver an amendment of the Lease reflecting the lease of the
applicable portion of ROFR Space #3 by Lessor to Lessee on the terms and
provisions set forth in this Section, which amendment shall be executed and
delivered within thirty (30) days after Lessee exercises the ROFR Space #3
Refusal Right.

     (g) The ROFR Space #3 Refusal Right shall automatically terminate and
become null and void upon the earlier to occur of (1) the expiration or
termination of the Lease, (2) the termination of Lessee's right to possession
of the Premises, (3) the assignment of the Lease by Lessee, in whole or in part,
which is not in accordance with Section 14 of the Original Lease, or which is to
a party (or any affiliate thereof) who is then, or was within the preceding six
(6) months, a tenant in, or otherwise an occupant of, the Building, (4) the
sublease by Lessee of the Premises, or any part thereof, which is not in
accordance with Section 14 of the Original Lease, or which is to a party (or any
affiliate thereof) who is then, or was within the preceding six (6) months, a
tenant in, or otherwise an occupant of, the Building, or (5) the failure of
Lessee to timely or properly exercise a ROFR Space #3 Refusal Right. Without
limiting the foregoing, no ROFR Space #3 Refusal Right shall be assignable by
Lessee separately from the Lease nor shall any ROFR Space #3 Refusal Right be
exercisable by any party other than Lessee except for Lessee's assignee pursuant
to an assignment of the Lease in accordance with Section 14 of the Original
Lease which assignee (or any affiliate thereof) is not, at the effective date of
the assignment, or was not for the six (6) months preceding the effective date
of the assignment, a tenant in, or otherwise an occupant of, the Building.

     8. Extension Option. Section 37 of the Lease is hereby deleted in its
entirety and the following is substituted in its place and stead:

     (a) Subject to the terms, conditions and limitations set forth in this
Section 8, Lessee is hereby granted the option to extend (the "Option to
Extend") the Term of the Lease for one (1) renewal term of five (5) years
commencing September 1, 2007 (the "Extension Term Commencement Date"), and
expiring August 31, 2012 (the "Extension Term"), on the same terms and
conditions as are contained in the Lease, as amended hereby, except as follows:

                                      21

<PAGE>

     (i)   Lessor shall be under no obligation to make or pay for any further
improvements to the Premises;

     (ii)  Lessee shall have no further rights under this Section 8; and

     (iii) Commencing as of the first day of the Extension Term, Base Rent and
Rent Adjustments for the first Lease Year of the Extension Term shall be equal
to the greater of:

           A. Ninety percent (90%) of the then current Fair Market Base Rental
     (as hereinafter defined) plus Lessee's Proportionate Share of Taxes and
     Expenses allocable to the Premises; or

           B. the then current escalated Base Rent plus Lessee's Proportionate
     Share of Taxes and Expenses allocable to the Premises.

If the Base Rent for the first Lease Year of the Extension Term is determined to
be equal to ninety percent (90%) of the then current Fair Market Base Rental
pursuant to Section 8(a)(iii)A above, then such Base Rent shall be increased by
the Fair Market Escalation Rate (as hereinafter defined), compounded, on each
September 1 thereafter during the remainder of the Extension Term. If the Base
Rent for the first Lease Year of the Extension Term is determined to be equal to
the then current escalated Base Rent pursuant to Section 8(a)(iii)B above, then
the Base Rent shall be increased by two percent (2%), compounded, on each
September 1 thereafter during the remainder of the Extension Term. For the
purposes of this Section 8(a), "Fair Market Base Rental" shall be deemed to mean
the market base rental, net of all concessions, tax and expense "stops",
construction or other allowances or abatements, for comparable office space in
comparable first-class office buildings in the North Michigan Avenue market of
Chicago, Illinois, for lease terms equivalent to the Extension Term, in effect
on the Extension Term Commencement Date, as reasonably determined by Lessor; the
"Fair Market Base Rental Escalation Rate" shall be deemed to mean the annual
compounded escalation percentage rate being applied to such Fair Market Base
Rental for comparable office space in comparable first-class offices buildings
in the North Michigan Avenue market of Chicago, Illinois, for lease terms
equivalent to the Extension Term, in effect on the Extension Term Commencement
Date, as reasonably determined by Lessor; and the "North Michigan Avenue market
of Chicago, Illinois" shall be deemed to mean the area bounded by Lake Shore
Drive to the east, the Chicago River to the south, State Street to the west and
Oak Street to the north, together with the area bounded by Columbus Drive to the
east, Randolph Street to the south, Michigan Avenue to the west and the Chicago
River to the north. In the event that a dispute arises as to the reasonableness
of Lessor's determination of Fair Market Base Rental or Fair Market Base Rental
Escalation Rate, or both, (which, for purposes of ascertaining whether Lessor's
determination was reasonable, shall be deemed to have been made on the date
Lessor

                                      22

<PAGE>

     delivered notice of such determination to Lessee) and such dispute is not
     resolved, either by agreement of the parties or by the issuance of a final,
     unappealable order of a court of competent jurisdiction, prior to the
     Extension Term Commencement Date, then for the period commencing on the
     Extension Term Commencement Date and continuing to and including the date
     such dispute is resolved, either by agreement of the parties or by the
     issuance of a final, unappealable order of a court of competent
     jurisdiction, the Base Rent and the annual increases thereof payable by
     Lessee during such period shall be as determined by Lessor as provided
     above. In the event such resolution of such dispute results in an agreement
     by the parties or a determination in such court order that the Fair Market
     Base Rental or the Fair Market Base Rental Escalation Rate, or both, are
     lower than as determined by Lessor as provided above, such lower rate or
     rates shall be used to determine the Base Rent and the annual increases
     thereof payable by Lessee during the Extension Term as provided above,
     retroactive to the Extension Term Commencement Date, and, provided that
     Lessee is not then in Default under the Lease, as amended hereby, Lessee
     shall be entitled to offset the amount of any Base Rent overpaid by Lessee
     during such period against the then next due installments of Base Rent
     payable by Lessee hereunder until the full amount of such overpayment has
     been offset as provided herein. In the event such resolution of such
     dispute results in an agreement by the parties or a determination in such
     court order that neither the Fair Market Base Rental nor the Fair Market
     Base Rental Escalation Rate are lower than as determined by Lessor as
     provided above, the Base Rent and the annual increases thereof payable by
     Lessee during the Extension Term shall be as determined by Lessor as
     provided above.

     (b) Notwithstanding anything to the contrary contained in this Section 8,
Lessee's right to exercise the Option to Extend shall be contingent upon Lessee
not being in Default under the Lease, as amended hereby, either on the date
that Lessee exercises the Option to Extend or, unless waived in writing by
Lessor for purposes of the Option to Extend, on the Extension Term Commencement
Date. If Lessee is not in Default under the Lease, as amended hereby on the date
that Lessee exercises the Option to Extend but is so in Default on the Extension
Term Commencement Date and Lessor does not waive in writing such Default for
purposes of the Option to Extend, then, notwithstanding Lessee's exercise of the
Option to Extend, the Option to Extend shall be deemed to be terminated and of
no force and effect and the Term of the Lease shall expire or be terminated in
accordance with terms of the Lease as if Lessee had not been granted the Option
to Extend pursuant to this Section 8.

     (c) In order to exercise the Option to Extend, Lessee shall deliver to
Lessor written notice of such exercise ("Lessee's Extension Option Exercise
Notice") prior to March 1, 2006 (the "Extension Option Deadline"), and otherwise
satisfy the terms and conditions of this Section 8, or the Option to Extend
shall lapse and be of no further force or effect.

     (d) Lessee may, by notice given to Lessor not later than December 1, 2005,
request Lessor to provide Lessee with an estimate of the Fair Market Base Rental
and Fair Market Base Rental Escalation Rate that Lessor then believes in good
faith is likely to be in effect on the

                                      23
<PAGE>

Extension Term Commencement Date and, in such case, (i) Lessor shall provide
Lessee with such estimate on or before February 15, 2006, and (ii) except as
otherwise expressly provided herein, such estimate shall be deemed to be the
then current Fair Market Base Rental and Fair Market Base Rental Escalation Rate
for purposes of determining Base Rent and the annual increases thereof during
the Extension Term pursuant to Section 8(a)(iii)A above.

     (e) The provisions of this Section shall apply to the entire Premises
leased by Tenant hereunder as of the day immediately preceding the Extension
Term Commencement Date including, without limitation, any and all Option Space,
Primary ROFR Space, Secondary ROFR Space and ROFR Space #3 actually leased by
Lessee pursuant to the Fourth Amendment.

     (f) In consideration of Lessor agreeing to provide that the lease term for
any and all ROFR Space leased pursuant to Lessee's exercise of any Primary ROFR
Refusal Right, any Secondary ROFR Refusal Right and/or any ROFR Space #3 Refusal
Right (individually and collectively, any "Refusal Right") shall expire on the
last day of the Term of the Lease, as amended hereby, it is agreed that in the
event that (i) Lessee shall have actually leased any ROFR Space as a result of
exercising any such Refusal Right, (ii) the Term of the Lease, as amended
hereby, is terminated prior to the Expiration Date or is not extended pursuant
to the Option to Extend and (iii) the expiration date of the lease term for such
ROFR Space as set forth in the applicable Lessor's Notice exercising such
Refusal Right was later than the last day of the Term of the Lease, as amended
hereby, Lessee shall pay to Lessee a sum (the "Termination Fee") equal to the
aggregate amount of Base Rent and the Rent Adjustment due and payable under the
Lease, as amended hereby, for the last twelve (12) full calendar months
immediately preceding the Expiration Date with respect to any and all such
leased ROFR Space for which the applicable Lessor's Notice specified a
termination date later than the last day of the Term of the Lease, as amended
hereby, but not with respect to any other portion of the Premises, provided that
for purposes of calculating the Termination Fee in the event the Lease is
terminated prior to the Expiration Date, the aggregate amount of Base Rent and
Rent Adjustment due and payable for such twelve (12) month period shall be
determined as if the Lease had not been so terminated. If the Lease is not
extended pursuant to the Extension Option because Lessee does not properly
exercise the Option to Extend prior to the Extension Option Deadline, the
Termination Fee, if any, shall be due and payable on or before April 1, 2006. If
the Term of the Lease is not extended pursuant to the Extension Option as a
result of a Default being in existence on the Extension Term Commencement Date
or if the Lease is terminated prior to the Expiration Date as a result of the
existence of a Default, the Termination Fee, if any, shall be due and payable
within seven (7) days after Lessee receives notice from Lessor of the
termination of either the Extension Option or the Lease, as the case may be. The
Termination Fee, if any, payable by Lessee pursuant to this Section 8(f) shall
be in addition to, and not in lieu of, any other amounts payable by Lessee under
the Lease, as amended hereby, including, without limitation, Base Rent, Rent
Adjustment and damages (liquidated or otherwise) payable by reason of Lessor's
exercise of its remedies upon Default by Lessee.

                                      24
<PAGE>

     9.   TERMINATION OPTION. Any and all rights of Lessee to terminate the
Lease as set forth in Section 43 of the Original Lease, Section 6 of the First
Amendment and Section 5 of the Third Amendment are hereby deleted and shall be
of no further force and effect.

     10.  TENANT IMPROVEMENT ALLOWANCE. In consideration for entering into this
Fourth Amendment, and subject to the terms, conditions and limitation set forth
in this Section 10, Lessor shall make a contribution in the amount of Two
Hundred Fifty Thousand and No/100 Dollars ($250,000.00) ("Lessor's
Contribution") toward payment of the cost and expense of Lessee refurbishing the
Premises (or any portion thereof) within ninety (90) days after Lessee's written
request for such contribution is delivered to Lessor, provided such request is
delivered not earlier than September 1, 1999, and not later than August 31,
2001. Lessee's right to receive payment of Lessor's Contribution shall be
contingent upon (a) Lessee not being in default or breach under the Lease, as
amended hereby, at the time Lessee so requests payment and (b) Lessee, at such
time, having completed the work for which Lessor's Contribution is being so
requested in accordance with the terms of Section 13 of the Original Lease and
having submitted to Lessor contractors affidavits and full and final waivers of
lien and receipted bills for labor and materials expended and used for such
work. In the event that Lessee has satisfied all conditions and requirements as
set forth herein and in the Lease for the payment of Lessor's Contribution and
Lessor fails to pay in full Lessor's Contribution to Lessee within ninety (90)
days after Lessee's request therefor as aforesaid and provided that Lessee is
not then in breach or default under the Lease, as amended hereby, Lessee shall,
upon the expiration of said ninety (90) day period, be entitled to offset the
unpaid amount of Lessor's Contribution from the then next due installments of
Base Rent thereafter payable by Lessee under the Lease, as amended hereby,
until the full amount of Lessor's Contribution has been paid or offset as
provided herein. In the event Lessee fails to deliver such request for Lessor's
Contribution as required hereby on or before August 31, 2001, Lessee's right to
request Lessor's Contribution shall be deemed waived and of no further force and
effect and Lessor shall be relieved of any obligation to make Lessor's
Contribution.

     11.  BROKER. Lessee represents to Lessor that Lessee has not dealt with any
real estate broker, salesperson or finder in connection with this Amendment
other than Golub & Company (the "Broker"), and no other such person initiated or
participated in the negotiation of this Amendment or is entitled to any
commission in connection herewith. Lessee hereby agrees to indemnify, defend and
hold Lessor, its property manager and their respective employees harmless from
and against any and all liabilities, claims, demands, actions, damages, costs
and expenses (including attorneys' fees) arising from a claim for a fee or
commission made by any broker (other than the Broker), claiming to have acted by
or on behalf of Lessee in connection with this Amendment.

     12.  SUBMISSION. Submission of this Amendment by Lessor or Lessor's agent,
or their respective agents or representatives, to Lessee for examination and/or
execution shall not in any manner bind Lessor and no obligations on Lessor shall
arise under this Amendment unless and

                                      25
<PAGE>

until this Amendment is fully signed and delivered by Lessor and Lessee;
provided, however, the execution and delivery by Lessee of this Amendment to
Lessor or Lessor's agent, or their respective agents or representatives, shall
constitute an irrevocable offer by Lessee on the terms and conditions herein
contained, which offer may not be revoked for fifteen (15) days after such
delivery.

     13.  EFFECT OF AMENDMENT. As amended by this Amendment, the Lease shall
remain in full force and effect.

     14.  EXCULPATORY PROVISIONS. It is expressly understood and agreed by and
between the parties hereto, anything herein to the contrary notwithstanding,
that each and all of the representations, warranties, covenants, undertakings
and agreements herein made on the part of Lessor while in form purporting to be
the representations, warranties, covenants, undertakings and agreements of
Lessor are nevertheless each and every one of them made and intended, not as
personal representations, warranties, covenants, undertakings and agreements by
Lessor or for the purpose of or with the intention of binding Lessor personally,
but are made and intended for the purpose only of subjecting Lessor's interest
in the Office Area and the Premises to the terms of this Amendment and for no
other purposes whatsoever, and in case of default hereunder by Lessor (or
default through, under or by any of its beneficiaries, or agents or

                        MEMORANDUM OF FOURTH AMENDMENT
                        ------------------------------

     THIS MEMORANDUM OF FOURTH AMENDMENT ("Memorandum") is made as of this 6th
day of August, 1996, between AMERICAN NATIONAL BANK AND TRUST COMPANY OF
CHICAGO, not individually, but solely as Trustee under Trust Agreement dated May
2, 1989 and known as Trust No. 108237-06 (herein called the "Lessor") and
PLAYBOY ENTERPRISES, INC., a Delaware corporation (herein called the "Lessee").
Capitalized terms used herein shall have the same meaning as set forth in the
Lease (defined below) unless expressly defined herein or the context clearly
indicates to the contrary.


                             W I T N E S S E T H:
                             - - - - - - - - - -

     Lessor is the owner of a certain mixed used building located in Cook
County, Illinois, of which one or more of four components as are legally
described in Exhibit A attached hereto, as may be affected by this Memorandum.
The components are defined in Exhibit A as the Office Parcel, the Lot 1 Parcel,
the Skylight Parcel and the Garage Parcel.

     The building containing the four components is now commonly known as 680
North Lake Shore Drive, Chicago, Illinois.

     Lessor has leased to Lessee a portion of the Office Parcel consisting of
the entire fifteenth (15th) and sixteenth (16th) floors (the "Premises")
together with certain rights and privileges with respect to the Skylight Parcel,
the Garage Parcel and the Lot 1 Parcel for the Term and upon and subject to the
covenants, provisions and conditions contained in that certain Office Lease
dated as of April 7, 1988 entered into between the parties hereto, or their
predecessors-in-interest, (the "Lease") and as such document has been amended by
those certain Amendments dated October 26, 1989, June 1, 1992, August 30, 1993
and August 6, 1996 (the "Amendments") between Lessor and Lessee. The Amendments
and all of their respective covenants, provisions and conditions are by this
reference expressly incorporated herein and made a part of this Memorandum of
Amendment and all shall take notice thereof whether or not

<PAGE>

hereinafter more particularly described. The Amendments' covenants and
provisions affecting all Parcels are binding on the Lessor and its successors
and assigns as owners of any said Parcels.

     Without limitation, it is hereby disclosed that the Fourth Amendment
includes terms and provisions which (among other things) (a) provided that
Lessor grants to Lessee certain expansion rights and rights of first refusal on
certain office space on the 14th floor of the Building, and (b) contemplate
that the existence of this Fourth Amendment be disclosed and reference made to
its terms and provisions by means of this Memorandum.

     Lessee hereby appoints Lessor as its attorney-in-fact to record a Release
of this Memorandum executed by Lessor for itself and on Lessee's behalf, upon
the occurrence of any one of the following:

           I.  Expiration of the Lease at either August 31, 2007, or August 31,
     2012, or otherwise according to its terms; or

          II.  Termination of the Lease; or

         III.  Issuance of a nonappealable final order of any court with
     jurisdiction over the Premises granting possession of the Premises to
     Lessor; or

          IV.  Ninety (90) days after written notice from Lessor to Lessee that
     Lessor intends to record such Release, because Lessee has voluntarily
     abandoned the Premises, it being acknowledged that, for the purposes of
     this paragraph "abandoned" does not include an approved subletting or
     assignment.

     In addition, Lessee hereby appoints Lessor as its attorney-in-fact to
record a Release of this Memorandum as to the Garage Parcel in the event Lessor
or its successors or assigns exercises its option under the Lease to purchase
such parking rights from Lessee.

     This Memorandum and the Fourth Amendment are expressly subject to an
subordinate to the Easements (as defined in the Lease) and to any and all
mortgages now or hereafter encumbering the Office Parcel, and Lot 1 Parcel, the
Garage Parcel or the Skylight Parcel.

     Lessor and Lessee have entered into this Memorandum of Fourth Amendment-in
order that third parties may have notice of the existence of the Amendment and
some of its specific provisions. This Memorandum of Amendment is not intended
to amend, modify or otherwise change the terms and conditions of the
Lease or the Fourth Amendment nor shall provisions of this Memorandum of Fourth
Amendment be used in interpreting the provisions of the Lease or the Fourth
Amendment. In the event of a conflict between this Memorandum of Fourth
Amendment and the Fourth Amendment, the Fourth Amendment shall control.
<PAGE>

     IN WITNESS WHEREOF, the parties have executed this Memorandum of Fourth
Amendment as of the date and year first above written.
