Sample Business Contracts


UK-London-80/110 New Oxford Street, 4th Floor, Lease - Britel Fund Trustees Ltd. and CMGI (UK) Ltd.

Lease Forms

  • 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.
  • 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.
  • 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 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.
  • 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.

<PAGE>

           6.3.1     If the Premises are unfit for occupation and use because of

           default of the Tenant) the Principal Rent and the Service Charge (or
           a fair proportion according to the nature and extent of the damage)
           shall be suspended until the earlier of:

                     (i)  the date on which the Premises are again fit for
                          occupation and use; and

                     (ii) the expiry of the loss of rent insurance period;

           PROVIDED THAT if the Premises or the appropriate part thereof (or

           of this Lease so as to render the Premises fit for occupation and use
           within four years after the date of the damage or destruction or if
           earlier by the date on which the said cesser of rent shall determine
           ("the Relevant Date") then either party may determine this Lease by
           serving one month's written notice on the other (such notice to
           expire within two months of the Relevant Date) whereupon this Lease
           shall cease and determine but without prejudice to any antecedent
           claims and all insurance monies received by the Landlord shall belong
           to it absolutely.

           6.3.2    If the Premises or any part thereof (or access thereto
           within the Building) have been damaged or destroyed by an Insured
           Risk so as to render the Premises incapable of beneficial use, then
           the Landlord will procure that the Landlord's architect will produce
           to the Landlord and the Tenant a report (the "Report") as soon as
           reasonably practicable and in any event within 90 days of the date of
           the damage or destruction which shall confirm whether or not the
           Premises can in the Landlord's architect's reasonable opinion be
           reinstated within four years from the date of the damage or
           destruction, so as to render the Premises again capable of beneficial
           use. If the Report does not state that in the Landlord's architect's
           reasonable opinion the Premises can be reinstated as expressed above,
           then either the Landlord or the Tenant may within two weeks from
           receipt of the Report terminate this Lease by giving two weeks'
           written notice thereafter following receipt

                                       28

           of the Report.

           6.3.3     Time shall be of the essence for the purpose of Clause
           6.3.2. Termination of this Lease pursuant to Clause 6.3.2 shall be
           without prejudice to the rights of either party against the other in
           respect of any antecedent breach of covenant.

           6.3.4     Any dispute relating to this Clause 6.3 shall be referred
           to Arbitration.

           days, and if the Tenant fails to comply with such notice the Landlord
