                                    EXHIBIT B

Lessor shall be responsible for improvements to the Additional Space to
accommodate access to interior office space not included in the Additional
Space. Such improvements shall include, but are not limited to, moving a lobby
wall along with the related electrical adjustments, modifying the front lobby
door as necessitated by moving the wall, and closing off access to the
Additional Space from the interior space not included in the Additional Space.
In addition, Lessor agrees to add a wall and door to close off a portion of the
kitchen area which includes the water heater, for which Lessee agrees to
reimburse Lessor $3,000.00. Lessee agrees to install cabinets in the kitchen
area for which Lessor agrees to reimburse Lessee $2,500.00. These two
reimbursable items may be offset, which results in a net amount due to Lessor by
Lessee of $500.00.
