  • 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.

     another Rent Review Surveyor to act in his place and in the same capacity

     before the Review Date up to the date on which payment is due

     determined a memorandum recording the increased Basic Rent (or the fact
     that there is no increase) shall be executed by the parties and attached to
     this Lease and the Counterpart but that memorandum shall be regarded as
     evidential only and its absence shall not affect the liability of the
     Tenant to pay any increased Basic Rent

9    Time is not of the essence in this schedule

10   For the purpose of this schedule the Open Market Rent shall be deemed to
     have been determined on the date of the Rent Review Surveyor's award or

1    At all times during the Term until the Tenant has lawfully assigned this
     Lease with the consent of the Landlord in accordance with this Lease the

     punctually paid and the several conditions and stipulations on the Tenant's

     in respect of which such default has occurred and will make good to the
     Landlord on demand and will indemnify the Landlord against all losses

     of such non-payment non-performance or non observance provided always that
     the liability of the Guarantor will not in any way be released lessened or
     affected by:

1.1  Any time or indulgence granted by the Landlord to the Tenant or any
     neglect or forbearance of the Landlord in enforcing the payment of the
     rents or the observance or  performance of the covenants or other terms of
     this Lease or any refusal by the Landlord to accept rents tendered by or on
     behalf of the Tenant at a time when the Landlord was entitled (or would
     after the service of a notice under the Law of Property Act 1925 Section
     146 have been entitled) to re-enter the Premises

1.2  The fact that part of the Premises may have been surrendered in which
     event the liability of the Guarantor will continue in respect of the part
     of the Premises not so surrendered after making any necessary
     apportionments under the Law of Property Act 1925 Section 140 unless such
     surrender makes that part of the Premises not so surrendered considerably
     more difficult to alienate

1.3  Any agreement between the Landlord and the Tenant or any determination made
     by an arbitrator or expert relating to any rent review as provided in this
     Lease and so that any rent agreed or
<PAGE>

     determined on such rent review will be deemed to be properly agreed or
     determined notwithstanding any failure to adhere to the prescribed
     procedures or timetables or the inclusion or exclusion of any item which
     should have been excluded or included in determining the reviewed rent

2    If the Tenant (being an individual) becomes bankrupt or (being a company)
     enters into liquidation and the Trustee in Bankruptcy or Liquidator
     disclaims this Lease then if so required by written notice given by the
     Landlord within 6 months after such disclaimer the Guarantor will accept
     from the Landlord a lease of the Premises in their then actual state or
     condition subject to any underlease or tenancy or other interest affecting
     the Premises or any part of them for a term equal to the residue of the
     Term which would have remained had there been no disclaimer at the same
     rent as that then payable under this Lease and subject to the same
     covenants provisions and conditions in all respects as those contained in
     this Lease (including the proviso for re-entry and rent review dates co-
     incident with those contained in this lease) such new lease to take effect
     from the date of disclaimer

3    If the Landlord so requires the new lease will contain an express
     covenant (in addition to all other covenants and provisions as mentioned or
     specified above) by the Guarantor (as tenant) immediately to carry out and
     complete at its own expense all works (whether of repair decoration or
     otherwise) which are required to remedy any breach of the covenants
     provisions and conditions of this Lease which occurred prior to the grant
     of such new lease

4    In any such case the Guarantor shall pay the costs of the new lease and
     will execute and deliver to the Landlord a counterpart of it

5    It is agreed and declared that the liability of the Guarantor is as
     principal covenant or with the Landlord and not merely collateral to the
     principal liability of the Tenant

6    Nothing in this Lease shall impose upon the Guarantor:

6.1  any requirement to guarantee in any way the performance of any covenant
     by any person other than the Tenant

6.2  any liability restriction or other requirement (of whatever nature) in
     relation to any time after the Tenant is released from any covenant by
     virtue of the Landlord and Tenant (Covenants) Act 1995 or

6.3  any liability in respect of the Tenant's performance of any covenant
     which is more onerous than that to which the Guarantor would be subject if
     it were the sole or principal debtor in respect of that covenant

7    To the extent that this Lease purports to impose upon the Guarantor any
     requirement  liability or   restriction referred to in paragraph 6 of this
     schedule the relevant provision of this Lease shall to that extent only be
     void but this shall not affect:

7.1  the enforceability of that provision except to that extent or

7.2  the enforceability of any other provision of this Lease

8    The liability of the Guarantor hereunder shall not extend to obligations
     of the Tenant arising under a "relevant variation" as defined in section
     18(4) of the Landlord and Tenant (Covenants) Act 1995 but the making of the
     relevant variation shall not otherwise discharge the Guarantor's liability
     under this Lease

1    On the Review Date the Basic Rent shall be reviewed in accordance with
     this schedule and the Basic Rent payable in respect of the Review Period
     shall be the higher of the Basic Rent payable immediately before that
     Review Period (ignoring for this purpose any rent cesser under paragraph 3
     of schedule 5 then current) and the Open Market Rent on the Review Date

2    The Landlord and the Tenant shall seek to agree the amount of the Open
     Market Rent in respect of the Review Period but if they have not agreed it
     by the date three months before the Review Date then either party may
     require the matter to be determined by the Rent Review Surveyor

3    The Rent Review Surveyor shall be a professionally qualified chartered
     surveyor or valuer and shall be previously agreed upon between the Landlord
     and the Tenant or (in the absence of such agreement prior to the date one
     month before the relevant Review Date) nominated on the application of
     either the Landlord or the Tenant or both of them jointly by the President
     and in the event of a sole application by the Landlord or the Tenant the
     party making such application shall on the date of the application provide
     a copy thereof to the other party

4    The Rent Review Surveyor shall act as an arbitrator in accordance with the
     Arbitration Act 1996 unless the Landlord and the Tenant shall agree
     otherwise in writing before the Rent Review Surveyor is appointed in which
     case he shall:

     (a)   act as an expert and

     (b)   allow the parties a reasonable opportunity of making representations
           and counter-representations to him and

     (c)   take those representations and counter-representations into account
           and

     (d)   if required by either party give written reasons for his
           determination

5    The award of the Rent Review Surveyor shall be binding on the parties and
     the costs of the reference to him and of his determination ( including his
     own fees and expenses and the legal and other costs of the parties) shall
     lie in his award

6    If the Rent Review Surveyor dies or becomes unwilling to act or becomes
     incapable of acting or the President may upon the application of either the
     Landlord or the Tenant or both of them jointly discharge him and appoint
     another Rent Review Surveyor to act in his place and in the same capacity
     and this shall be repeated as many times as the circumstances may require

7    If for any reason the Open Market Rent is not agreed or determined until
     after the Review Date the Tenant shall continue to pay the Basic Rent at
     the rate applicable immediately before that date and on the day 7 days
     after the day on which the Open Market Rent is agreed or determined the
     Tenant shall pay the amount of any increase for the period from and
     including the relevant Review Date up to the Quarter Day following that
     agreement or determination together with interest on each part of that
     payment at 4 per centum below the Interest Rate for the period on and from
     the date on which that part would have been payable had the Open Market
     Rent been agreed before the Review Date up to the date on which payment is
     due

8    Within twenty-eight days of the Open Market Rent being agreed or
     determined a memorandum recording the increased Basic Rent (or the fact
     that there is no increase) shall be executed by the parties and attached to
     this Lease and the Counterpart but that  memorandum shall be regarded as
     evidential only and its absence shall not affect the liability of the
     Tenant to pay any increased Basic Rent

9    Time is not of the essence in this schedule

10   For the purpose of this schedule the Open Market Rent shall be deemed to
     have been determined on the date of the Rent Review Surveyor's award or
     determination

                                  Schedule 10
                                  -----------

                             Guarantors Covenants
                             --------------------


     The Guarantor covenants with the Landlord including (without the need for
     any express assignment) its successors in title that:

1    At all times during the Term until the Tenant has lawfully assigned this
     Lease with the consent of the Landlord in accordance with this Lease the
     rents reserved by and all other sums payable pursuant to this Lease will be
     punctually paid and the several conditions and stipulations on the Tenant's
     part contained in this Lease will be duly performed observed and kept and
     if at any time during the Term until such assignment as is mentioned above
     there is default in the payment of the rents or in the observance or
     performance of any of the covenants or other terms of this Lease the
     Guarantor will pay the rents and observe or perform the covenants or terms
     in respect of which such default has occurred and will make good to the
     Landlord on demand and will indemnify the Landlord against all losses
     damages costs and expenses arising or incurred by the Landlord as a result
     of such non-payment non-performance or non-observance provided always that
     the liability of the Guarantor will not in any way be released lessened or
     affected by:

1.1  Any time or indulgence granted by the Landlord to the Tenant or any
     neglect or forbearance of the Landlord in enforcing the payment of the
     rents or the observance or performance of the covenants or other terms of
     this Lease or any refusal by the Landlord to accept rents tendered by or on
     behalf of the Tenant at a time when the Landlord was entitled (or would
     after the service of a notice under the Law o  Property Act 1925 Section
     146 have been entitled) to re-enter the Premises

1.2  The fact that part of the Premises may have been surrendered in which
     event the liability of the Guarantor will continue in respect of the part
     of the Premises not so surrendered after making any necessary
     apportionments under the Law of Property Act 1925 Section 140 unless such
     surrender makes that part of the Premises not so surrendered considerably
     more difficult to alienate

1.3  Any agreement between the Landlord and the Tenant or any determination
     made by an arbitrator or expert relating to any rent review as provided in
     this Lease and so that any rent agreed or determined on such rent review
     will be deemed to be properly agreed or determined notwithstanding any
     failure to adhere to the prescribed procedures or timetables or the
     inclusion or exclusion of any item which should have been excluded or
     included in determining the reviewed rent

2    If the Tenant (being an individual) becomes bankrupt or (being a company)
     enters into liquidation and the Trustee in Bankruptcy or Liquidator
     disclaims this Lease then if so required by written notice given by the
     Landlord within 6 months after such disclaimer the Guarantor will accept
     from the Landlord a lease of the Premises in their then actual state or
     condition subject to any underlease or tenancy or other interest affecting
     the Premises or any part of them for a term equal to the residue of the
     Term which would have remained had there been no disclaimer at the same
     rent as that then payable under this Lease and subject to the same
     covenants provisions and conditions in all respects as those contained in
     this Lease (including the proviso for re-entry and rent review dates co-
     incident with those contained in this lease) such new lease to take effect
     from the date of disclaimer

3    If the Landlord so requires the new lease will contain an express
     covenant (in addition to all other covenants and provisions as mentioned or
     specified above) by the Guarantor (as tenant) immediately to carry out and
     complete at its own expense all works (whether of repair decoration or
     otherwise) which are required to remedy any breach of the covenants
     provisions and conditions of this Lease which occurred prior to the grant
     of such new lease

4    In any such case the Guarantor shall pay the costs of the new lease and
     will execute and deliver to the Landlord a counterpart of it

5    It is agreed and declared that the liability of the Guarantor is as
     principal covenantor with the Landlord and not merely collateral to the
     principal liability of the Tenant

6    Nothing in this Lease shall impose upon the Guarantor:
<PAGE>

6.1.1  any requirement to guarantee in any way the performance of any covenant 
       by any  person other than the Tenant

6.2    any liability restriction or other requirement (of whatever nature) in
       relation to any time after the Tenant is released from any covenant by
       virtue of the Landlord and Tenant (Covenants) Act 1995 or

6.3    any liability in respect of the Tenant's performance of any covenant
       which is more onerous than that to which the Guarantor would be subject
       if it were the sole or principal debtor in respect of that covenant

7      To the extent that this Lease purports to impose upon the Guarantor any
       requirement liability or restriction referred to in paragraph 6 of this
       schedule the relevant provision of this Lease shall to that extent only
       be void but this shall not affect:

7.1    the enforceability of that provision except to that extent or

7.2    the enforceability of any other provision of this Lease

8      The liability of the Guarantor hereunder shall not extend to obligations
       of the Tenant arising under a "relevant variation" as defined in section
       18(4) of the Landlord and Tenant (Covenants) Act 1995 but the making of
       the relevant variation shall not otherwise discharge the Guarantor's
       liability under this Lease
