**WHEREAS**

**WHEREAS**

**NOW      THEREFORE**

| **1.  ** | **New                Size of the Premises**.                The Premises as drawn on Exhibit “A” of this Amendment to Lease shall                demonstrate the new Premises. The Premises shall comprise 15,067                rentable                square feet. Lessor shall, at its own cost, build the demising wall                that                will separate the Premises from the adjacent tenant. Lessee shall                be                responsible for maintaining the Premises as stated in the Lease and                the                previous Amendments of the Lease. |

| **2.  ** | **Lessee’s                Maintenance Obligation**.                Lessee shall be responsible for the maintenance of the newly added                portion                of the Premises that was formerly known as the Common Area Restrooms,                after the construction and completion of the Demising Wall that has                been                built to separate the Premises from the adjacent tenant’s                premises. |
|--------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| **3.  ** | **HVAC                for the Newly Added Portion of the Premises**.                Currently, the HVAC that services that restrooms located in the newly                added portion of the Premises is being serviced by the adjacent tenant.                Lessee acknowledges this fact and understands that the adjacent tenant                is                currently responsible for maintaining this unit and has no current                plans                to alter this situation. Lessor shall act as a facilitator to attempt                to                keep the restrooms’ HVAC operational and temperature reasonably                maintained. Lessee further acknowledges that it may, at its own expense,                at a later date, adjust the ducts and air flow within its restroom                areas                so that is’ own HVAC system services this area and therefore not the                adjacent tenant’s HVAC system (servicing this                area). |

| 4.   | Lessor                shall not be responsible for the cost and construction of any of                the work                that Lessee wishes to perform to modify its own plans within its’ Premises                other than constructing the Demising wall. Furthermore, Lessor shall                not                be required to install the Network Telephone Wall by the restrooms                that                was previously mentioned in the Amendment prior to this one. Lessor                shall                not be required to “shorten the wall” for the Common Area Restrooms since                there will no longer be any common area                restrooms. |

| 5.   | Lessor                shall be responsible to cut in and frame the Network Telephone logo                window. Lessee shall pay for the cost of the window, glass, and mullion                frame around the window. |

| 7.   | If                at any time in the future, a governing authority deems that the restroom                plan for the adjacent tenant can not be reasonably adjusted to meet                the                proper building code, then Lessor shall have the right, but not the                obligation, to immediately nullify this Amendment for this sole reason                and                shall rebuild the walls mentioned at its’ cost and the rentals shall                adjust accordingly from the time of substantial completion of the                common                area restroom walls that will be                created. |
