B. Lessor and Lessee are willing to enter into this Lease for the foregoing purposes, all subject to the terms and conditions set forth herein. This Lease expressly supplants and supersedes any prior lease for the Real Property and Demised Premises (hereinafter defined).

2. LEASE TERM. This Lease shall begin on the Effective Date and shall continue until December 31, 2014, such term being defined herein as the “Term”. Provided Lessee is not in default under this Lease, Lessee shall have the option to extend for Term for an unlimited number of successive one (1) year periods on the same terms and conditions set forth herein (each, an “Extension Option”). Lessee must exercise each Extension Option by written notice to Lessor on or before sixty (60) days prior to expiration of the Term, as same may have been previously extended.

3. RENT. As base rent for the Demised Premises, beginning on the Effective Date and continuing on the first day of each month thereafter during the first two years of the Term, Lessee will pay to Lessor the monthly sum of $8,750. The base rent shall be increased on the second anniversary of the Effective Date and every two years thereafter to an amount equal to the “Fair Market Value” of rental amounts of comparable properties in the area of the Real Property. In the event the Effective Date falls on a day other than the first day of a month. Lessee’s first base rent payment shall be prorated accordingly. In addition to such base rent, within ten (10) business days following receipt of an invoice from Lessor, Lessee shall pay, as additional rent, to the extent not paid directly by Lessee, the cost of Lessor’s insurance on the Demised Premises as provided in Section 10, all real property taxes on the Demised Premises, and all utility, repair and maintenance expenses incurred by Lessor to the extent not covered by the insurance carried by Lessor under this Lease. It is intended by the parties hereto that this Lease is a “net” Lease. Lessor and Lessee shall attempt in good faith to agree as to Fair Market Value. In the event Lessor and Lessee cannot so agree within twenty (20) days after such discussions commence, Lessor and Lessee shall each select one real estate broker licensed in the state of where the Demised Premises is located (collectively, the “Brokers”) within ten (10) days after the twenty (20) day period stated above; following which Brokers shall attempt in good

1

faith to determine the Fair Market Value. In the event the Brokers cannot so agree within twenty (20) days after such discussion commence, the Brokers shall select a third real estate broker licensed in the state where the Demised Premises is located (“Third Broker”) within ten (10) days after the twenty (20) day period stated above. Each of the Brokers shall submit their figure for Fair Market Value to the Third Broker within ten (10) days after the selection of the Third Broker. Within twenty (20) days after such submittals to the Third Broker, the Third Broker shall produce its own figure for Fair Market Value. The Fair Market Value for shall be conclusively determined by averaging the Third Broker’s determination of Fair Market Value with that determination previously submitted by the Brokers which is numerically closest to the Third Broker’s determination.

4. UTILITIES. Lessee shall pay when due all utility bills for electricity, water, gas and any other services consumed by Lessee at the Demised Premises. In no event shall Lessor be liable to Lessee for an interruption or failure in the supply of any such utilities to the Demised Premises, except to the extent such interruption or failure is caused by the gross negligence or willful misconduct of Lessor.
