            2.2   Prohibited Uses

            Tenant shall not store or do or permit anything to be stored or done
in or about the Equipment Space which will in any way conflict with any law,
ordinance or governmental rule or regulation now in force or which may hereafter
be enacted or promulgated, or which will obstruct or interfere with the rights
of other tenants of the Building or the Project or injure or annoy them, or

constituted relating to or affecting the condition, use or items stores in the
Equipment Space.

            2.3   Landlord Not Liable For Personal Property

            Tenant recognizes that Landlord does not have insurance coverage for
any personal property belonging to Tenant, its employees, agents, or invitees
that may be kept in the Equipment Space. Tenant shall provide whatever insurance
coverage Tenant deems necessary and Tenant accepts complete liability and all
risk of loss which may arise from damage to or loss of the property kept by
Tenant within the Equipment Space due to the Function, fire, acts of God, theft,
vandalism, or any other cause not occurring as a result of the willful
malfeasance or gross negligence of Landlord. Tenant waives any and all rights of
subrogation against Landlord with respect to any insurance that Tenant may
obtain with respect to any property to be kept by Tenant within the Equipment
Space.

            2.4   Effect of Use on Insurance

            Tenant shall not do, omit to do, or permit to be done any act or
thing upon the Equipment Space which will invalidate or be in conflict with any
fire insurance policy covering part or all of the Equipment Space or which shall
or might subject Landlord to any liability or responsibility for injury to any
person or persons or to property by reason of any such act or thing or omission.
Tenant shall not store flammable or explosive liquids or materials, nor do or
permit anything to be done in or about the Equipment Space nor bring or keep
anything therein which shall be unlawful or which will in any way increase the
existing rate of or affect any fire or other insurance upon the Building or any
of its contents, or cause a cancellation of any insurance policy covering the
Building or the Project or any part thereof, nor shall Tenant sell or permit to
be stored, kept, used or sold in or about said Equipment Space any articles
which may be prohibited by a standard form policy of insurance. Without
limitation upon Landlord's remedies for Tenant's breach of this covenant, Tenant
shall promptly upon demand reimburse Landlord for any additional premium charged
under any such policy by reason of Tenant's failure to comply with the
provisions of this Paragraph 2.

      3.    ELECTRIC UTILITIES.

      Tenant shall pay the costs associated with installation of a separate
electrical panel and meter, if necessary, at time of installation for the
Equipment and shall be responsible for the electrical and any HVAC costs
attributable to the Equipment.

      and expense, prepare and deliver to Landlord working drawings, plans and
      specifications (the "Plans"), detailing the location and size of the
      Equipment specifically describing the proposed construction and work. No
      work shall commence until Landlord has approved the Plans, which approval
      will not be unreasonably withheld or unduly delayed. Tenant agrees to:

with generally accepted construction standards;

Equipment by or for Tenant, all roof, floor and wall penetrations must be
sealed. Tenant acknowledges that Landlord's review of Tenant's plans for the
installation of the Equipment: (a) shall only be for general conformance to
Landlord's established criteria, and (b) shall not include analysis of the
structural integrity of existing or new improvements nor of the adequacy of any
material or systems proposed by Tenant with respect to the Equipment. Tenant

agrees that Landlord is under no obligation to perform any work or provide any
materials to prepare the Equipment Space or the Building for Tenant.

      9.    ROOFTOP ACCESS

      Landlord shall provide Tenant access to the rooftop of the Building upon

supplier shall comply with Landlord's reasonable and insurance company imposed
requirements for the Building. If due to an emergency Tenant requires access to
the roof of the Building, and Tenant does not advise Landlord in advance of such
intended entry, Tenant shall notify Landlord on the business day immediately

Landlord may verify the re-locking of doors and compliance with security and
safety requirements.

proceedings any such liens.

      13.   PERFORMANCE OF WORK. Tenant may contract or subcontract any portion
