  • 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.

terminate this Sublease effective on the Early Termination Date, as defined in
the Master Lease, by giving Sublessee written notice of such election not less
than one hundred eighty (180) days prior to the Early Termination Date.

          (c)  In the event, for any reason whatsoever, that either Master

Sublessor shall give Sublessee at least one hundred eight), (180) days notice of

the term stated in the Basic Sublease Information of this Sublease had expired,
upon the Termination Date stated in the notice, and Sublessee shall surrender
the Premises on or before the Termination Date.  In the event Master Lessor or
Sublessor elects to demolish or substantially renovate the Building, Sublessor

obligations that have accrued prior to the Termination Date.

          3.  Rental.
              ------

          (a) Sublessee shall pay to Sublessor throughout the term of this
Sublease its rental for the Premises the sum specified in the Basic Sublease
Information as the Base Rent, provided that the rental payable during each
calendar year subsequent to the Base Year shall be the Base Rent, increased by
Sublessee's Percentage Share of the total dollar increase, if any, in Operating
Expenses paid or incurred by Sublessor in such year over the Base Operating
<PAGE>

Expenses, and also increased by Sublessee's Percentage Share of the total dollar
increase, if any, in Property Taxes paid by Sublessor in such year over the Base
Property Taxes.  The increased rental due pursuant to this Paragraph 3(a) is
hereinafter referred to as "Escalation Rent."
                            ---------------

          (b) Rental shall be paid to Sublessor, on or before the first day of
the term hereof and on or before the first day of each and every successive
calendar month thereafter during the term hereof.   In the event the term of
this Sublease commences on a day other than the first day of a calendar month or
ends on a day other than the last day of a calendar month, the monthly rental
for the first and/or last fractional months of the term hereof shall be
appropriately prorated.

          (c) All sums of money due to Sublessor hereunder not specifically
characterized as rental shall constitute additional rent and if any such sum is
not paid at the time provided in this Sublease, it shall nonetheless be
collectible as additional rent at any time thereafter, including without
limitation on the date on which the next installment of rental is due. Nothing
contained herein shall be deemed to suspend or delay the payment of any sum of
money at the time it becomes due and payable hereunder, or to limit any other
remedy of Sublessor.

          (d) Sublessee hereby acknowledges that late payment by Sublessee to
Sublessor of rent and other sums due hereunder after the expiration of any
applicable cure period will cause Sublessor to incur costs not contemplated by
this Sublease, the exact amount of which will be difficult to ascertain.  Such
costs include, but are not limited to, processing and accounting charges, and
late charges which may be imposed on Sublessor by the terms of the Master Lease
or any deed of trust or mortgage encumbering the Building or Sublessor's
leasehold interest in the Building.  Accordingly, if any installment of rent or
any other sums due from Sublessee shall not be received by Sublessor when due or
in the time period provided herein, Sublessee shall pay to Sublessor a late
charge equal to 10% of such overdue amount.  The parties hereby agree that such
late charge represents a fair and reasonable estimate of the costs Sublessor
will incur by reason of late payment by Sublessee.  Acceptance of such late
charge by Sublessor shall in no event constitute a waiver of Sublessee's default
with respect to such overdue amount, nor prevent Sublessor from exercising any
of the other rights and remedies granted hereunder.

          (e)  Any amount due to Sublessor, if not paid when due, shall
bear interest from the date due until paid at the rate equal to the lesser of
(i) the maximum rate then permitted by applicable usuary law, or (ii) the
reference rate, or succeeding similar index, of the Bank of America then in
effect from time to time plus two percent (2%).  Payment of interest shall not
excuse or cure any default hereunder by Sublessee, nor prevent Sublessor from
exercising any of the other rights and remedies granted hereunder.

          (f)  All payments due from Sublessee to Sublessor shall be paid
to Sublessor, without deduction, offset, notice or prior demand, in lawful money
of the United States of America at Sublessor's address for notices hereunder, or
to such other person or at such other place as Sublessor may from time to time
designate by notice to Sublessee.

   4.  Escalation Rent Payments.
       ------------------------

          Escalation Rent shall be paid monthly on an estimated basis, with
subsequent annual reconciliation, in accordance with the following procedures:
<PAGE>

          (a)  During December of the Base Year and December of each
subsequent calendar year, or as soon thereafter as practicable, Sublessor shall
give Sublessee notice of its estimate of any Escalation Rent due under Paragraph
                                                                       ---------
3(a) above for the ensuing calendar year.  On or before the first day of each
----
month during the ensuing calendar year, Sublessee shall pay to Sublessor 1/12th
of such estimated Escalation Rent, provided that if such notice is not given in
December, Sublessee shall continue to pay Escalation Rent on the basis of the
prior year's estimate until the month after such notice is given. If at any time
or times it appears to Sublessor that the Escalation Rent for the current
calendar year will vary from its estimate by more than 5%, Sublessor may, in its
sole discretion, by notice to Sublessee, revise its estimate for such year, and
subsequent payments by Sublessee of Escalation Rent for such year shall be based
upon such revised estimate.

          (b) Within 90 days after the close of each calendar year or as soon
after such 90-day period as practicable, Sublessor shall deliver to Sublessee a
statement of the actual Escalation Rent for such calendar year, accompanied by a
statement showing the Operating Expenses and Property Taxes on the basis of
which the actual Escalation Rent was determined.  The statement shall be final
and binding upon Sublessor and Sublessee as to the amount of the Operating
Expenses and Property Taxes.  If Sublessor's statement discloses that Sublessee
owes an amount that is less than the estimated payments for such calendar year
previously made by Sublessee, Sublessor shall credit such excess against the
next payment of rental due from Sublessee hereunder.  If Sublessor's statement
discloses that Sublessee owes an amount that is more than the estimated payments
for such calendar year previously made by Sublessee, Sublessee shall pay the
deficiency to Sublessor within 30 days after delivery of the statement.

          (c)  The amount of Escalation Rent for any fractional year in the

faithful performance by Sublessee of all the provisions of this Sublease to be
performed or observed by Sublessee.  If Sublessee fails to pay rent or other
sums due hereunder, or otherwise defaults with respect to any provision of this
Sublease, Sublessor may use, apply or retain all or any portion of the Security
Deposit for the payment of any rent or other sum in default or for the payment
of' any other sum to which Sublessor may become obligated by reason of
Sublessee's default, or to compensate Sublessor for any loss or damage which
Sublessor may suffer thereby.  If Sublessor so uses or applies all or any
portion of the Security Deposit, Sublessee shall within 10 days after demand
therefor deposit cash with Sublessor in an amount sufficient to restore the
Security Deposit to the full amount thereof and Sublessee's failure to do so,
shall be a material breach of this Sublease.  Sublessor shall not be required to
keep the Security Deposit separate from its general accounts. If Sublessee
performs all of Sublessee's obligations hereunder, the Security Deposit, or so
much thereof as has not theretofore been applied by Sublessor, shall be
returned, without interest, to Sublessee (or, at Sublessor's option, to the last
assignee, if any, of Sublessee's interest hereunder) at the expiration of the
term hereof, and after Sublessee has

<PAGE>

transaction or any document to which Sublessee is a party creating or
transferring an interest or an estate in the Premises. In the event that it

Sublessor's payment of the Additional Obligations, the monthly rental payable to
Sublessor shall be revised to net Sublessor the same net return without
reimbursement of the Additional Obligations as would have been received by
Sublessor with reimbursement of the Additional Obligations.

            -----------

          (a)  Sublessee shall not make or suffer to be made any

alterations, additions or improvements which affect the Building structure,
exterior, or plumbing system (hereinafter collectively referred to as
"Alterations"), without Sublessor's (and, if applicable, Master Lessor's) prior
written consent.  Sublessee acknowledges that certain Alterations also require
the consent of Master Lessor, and therefore Sublessee shall provide Sublessor
with not less than thirty (30) days advance written notice prior to the date on
which Sublessee desires Sublessor's consent.  Sublessee further acknowledges
that as to those certain Alterations requiring consent by the Master Lessor,
such Alterations may be approved, conditionally approved or disapproved by
Master Lessor.  If such Alterations are conditionally approved by Master Lessor,
Sublessee shall notify Sublessor within twenty (20) days of Master Lessor's
notice of conditional approval whether Sublessee shall either proceed with such
Alterations subject to the conditions specified by Master Lessor, or not proceed
with such Alterations.  All Alterations shall be made by Sublessor for
Sublessee's account in accordance with the procedures set forth in this section.
All Alterations shall immediately become Sublessor's property and, at the end of

of restoring the Premises to their condition prior to the installation of such
Alterations.

Paragraph 12 above shall be prepared at Sublessee's expense by its architect or

the nature of the Alterations, Sublessee shall cause any architect retained by
it to follow the standard construction administration procedures and to utilize
the standard specifications and details promulgated from time to time by
Sublessor for the Building.  The plans and specifications shall be subject to
further approval by Sublessor and Sublessee, which approval shall not be
unreasonably withheld by either party, and following such approval Sublessor
shall obtain quotations of the cost of the Alterations as reflected by the
approved plans and specifications from a contractor approved by Sublessor.
Sublessor shall enter into a contract for the construction or installation of
the Alterations with the contractor approved by Sublessor, and shall use

prior to commencing work on the Premises, provide Sublessor with a performance
bond and a labor and materials payment bond in the amount of the contract price
for the work naming Sublessor and Sublessee (and any other person designated by
Sublessor) as co-obligees.  Sublessee shall be responsible for performing, at
its sole cost and expense, any additional alterations and improvements
<PAGE>

required by law to be made to or in the Building as a result of any Alterations.
Sublessor itself does not warrant the cost of the Alterations, the timeliness of
performance or the quality of the contractor's work.

          (c) In the event Sublessor or the contractor is instructed by
Sublessee to proceed with any changes to the Alterations without a prior
determination of any increased costs resulting from such changes and without
approval of such increases by Sublessee, or in the event Sublessee is
responsible for increased costs attributable to a delay or acceleration in the
time for construction, the amount of any increased costs shall be as reasonably
determined by Sublessor upon completion of the Alterations. subject only to
Sublessor's reasonable efforts in causing the contractor to furnish Sublessee
appropriate back-up information concerning increased costs, if any.

          (d) The cost of the Alterations shall include the cost of
performing work at other than normal business hours to the extent such work
affects adjoining space and would unreasonably interfere with the ability of the
tenant or sublessee of the adjoining space to conduct its business therein
during normal business hours.  In consideration of the administration by
Sublessor or its agent of the constriction or installation of the Alterations,
including, without limitation, the supervision of the general contractor,
architect, engineers, and subcontractors, Sublessee shall pay to Sublessor a fee
equal to 5% of the total cost of the Alterations (the "Construction Management
                                                       -----------------------

          (e) Sublessee shall pay to Sublessor all amounts payable by
Sublessee pursuant to this Paragraph 12 within 10 days after billing by
                           ------------
Sublessor.  Bills may be rendered in advance of the Alterations so as to enable
Sublessor to pay the contractor, architect or engineer without advancing
Sublessor's own funds.

          (f) Subject to Sublessor's agreement to minimize any disturbance of
Sublessee's use of the Premises, Sublessor reserves the right at any time and
from time to time (without the same constituting an actual or constructive
eviction and without incurring any liability to Sublessee therefor or otherwise
affecting Sublessee's obligations under this Sublease) to make such changes,
alterations, additions, improvements, repairs or replacements in or to the
Project or the Building (including the Premises if required so to do by any law
or regulation) and the fixtures and equipment thereof, as well as in or to the
street entrances, halls, passages and stairways thereof, and to change the name
by which the Building is commonly known, as Sublessor may deem necessary or
desirable.  Nothing contained in this Paragraph 12 should be deemed  to relieve
                                      ------------
Sublessee of any duty, obligation or liability of Sublessee with respect to
making any repair, replacement or improvement or complying with any law, order
or requirement of any government or other authority and nothing contained in
this Paragraph 12 shall be deemed or construed to impose upon Sublessor any
     ------------
obligation, responsibility or liability whatsoever, for the care, supervision or
repair of the Project or any part thereof other than as otherwise provided in
this Sublease.

no obligation and has made no promise to alter, remodel, improve, repair,
decorate or paint the Premises or any part thereof, except as specifically

claims of lien for work performed or materials or supplies furnished to or for
the benefit of Sublessee, or persons having an interest in the Premises through

assigns, has either commenced or is about to commence, then upon the written
request of Master Lessor or Sublessor, or their respective successors or

compliance with any loan secured by the Building or Sublessor's leasehold
interest therein, so long as Sublessee receives written notice of such required
act from such lender.  Nothing herein contained shall be so construed to allow
such items to remain unpaid for such length of time as would permit the
Premises, or any part of thereof, to be foreclosed upon for the non-payment of
same.

enjoyment of the Premises occasioned by such entry. Notwithstanding the
immediately preceding sentence to the contrary, in the event Sublessor's entry

Master Lessor shall each have the right to use any and all means which Sublessor
or Master Lessor may deem proper to open Sublessee's doors in an emergency in
order to obtain entry to the Premises, and any entry to the Premises obtained by

shall release Sublessee of Sublessee's obligation or alter the primary liability
Of Sublessee to pay the rental and to perform all other obligations to be
performed by Sublessee hereunder.  The acceptance of rental by Sublessor from
any other person shall not be deemed to be a waiver by Sublessor of any
provision hereof.  Consent to one assignment or subletting shall not be deemed
consent to any subsequent assignment or subletting.  In the event of default by
any assignee of Sublessee or any successor of Sublessee in the performance of
any of the terms hereof, Sublessor may proceed directly against Sublessee
without the necessity of exhausting remedies against such assignee or successor.

the Premise or request the consent of Sublessor to any assignment, subletting,
hypothecation or other action requiring Sublessor's consent hereunder, then
