TO HAVE AND TO HOLD THE PREMISES upon the terms and conditions hereinafter set forth.

1. Term : The term of this Lease shall be for a period of one (1) year, commencing on February 26, 2006 (the “Commencement Date”), and ending at midnight on February 25, 2007, unless sooner terminated in accordance with the terms hereinafter provided.

2. Possession : If the Tenant accepts possession of the Premises before the Commencement Date specified hereinabove, the term and rental shall commence on such earlier date. If for any reason Landlord does not substantially complete construction of the Premises prior to the Commencement Date, such failure will not affect the validity of this lease, but in such case Tenant shall not be obligated to pay rent until such construction is substantially completed and possession of the Premises is delivered to Tenant. Landlord shall have no liability to Tenant for failure to substantially complete construction prior to any date or dates. Tenant’s occupancy of the Premises shall constitute acceptance of the work performed and completed by Landlord, unless otherwise agreed in writing by the parties.

3. Rent : The Tenant shall pay to the Landlord an total rental for the initial lease term of $98,648.00 (hereinafter referred to as the “Base Rent”), payable in advance, on the first day of each and every calendar month during the term thereof. The first installment shall be in the amount of $9,189.13, for the period of February 26, 2006 through March 31, 2006. The remaining monthly installments shall be in the amount of $8,132.62. All rent payments shall be made to Landlord at its principal office at 1330 Lady Street, Suite 503, Columbia, South Carolina 29201, or at such other place as the Landlord may designate in writing to Tenant. If rental commences on a date other than the first day of the month, rent for the first month shall be prorated and paid on or before date of possession. All rentals due hereunder which are not received by the Landlord by the tenth (10th) day of each month shall be subject to a delinquency charge of one and one-half

1

(1.5%) percent per month on the unpaid balance, computed from the first day of every month for which rental is due. Said delinquency charge shall be subject to the default provisions herein.

4. Base Rent Adjustment: On the first anniversary of the Commencement Date of this lease, and annually thereafter, the Base Rent payable by Tenant shall be increased in proportion to the percent change in the Consumer Price Index figure, as hereinafter defined, between the most recent Consumer Price Index figure published prior to the Commencement Date, and the most recent Consumer Price Index figure published prior to the particular anniversary date; provided, however, that in no event shall the rent for any month after such anniversary be less than the rent for the month immediately preceding such anniversary. As used herein, the term “Consumer Price Index” shall mean Consumer Price Index for All Urban Consumers (CPI-U) for the U.S. City Average of All Items, l982-l984=l00, or the successor of that Index, as published by the Bureau of Labor Statistics, U.S. Department of Labor. Should Landlord lack sufficient data to make the proper determination on the date of any adjustment, Tenant shall continue to pay the monthly rent payable immediately prior to the adjustment date. As soon as Landlord obtains the necessary data, Landlord shall determine the rent payable from and after such adjustment date and shall notify Tenant of the adjustment in writing via ordinary mail. Should the monthly rent for the period following the adjustment date exceed the amount previously paid by Tenant for that period, Tenant shall forthwith pay the difference to Landlord. Should the Consumer Price Index as above described cease to be published, a reasonably comparable successor index shall be selected by Landlord.

Assignment and Subletting : The Tenant shall not, without the prior written consent of the Landlord, such consent not to be unreasonably withheld, assign this Lease or any interest therein, or sublet the Premises or any part thereof, or permit the use of the Premises by any party other than the Tenant. Consent to one assignment or sublease shall not constitute a waiver of this provision with respect to subsequent transactions. Each subtenant or assignee shall be liable to Landlord for all obligations of the Tenant hereunder, but the Tenant shall not be thereby relieved of such obligations.

7. Improvements : The Demised Premises are being provided “as is”. All other improvements, alterations and additions to the Premises desired by Tenant shall be made only at Tenant’s expense, in good and workmanlike manner and in accordance with plans and specifications which have been previously approved in writing by the Landlord.

Landlord shall not be liable for loss or damage resulting from any defective condition in or about the Premises unless such loss or damage results from Landlord’s negligent or willful failure to remedy such condition within a reasonable time after Landlord receives notice of or becomes aware of such condition. Except as expressly provided above, Tenant shall, at its own expense, keep and maintain the Premises in good order and repair during the term of this Lease, and shall surrender same to Landlord at the expiration or earlier termination of this Lease in as good condition as they were when received (or subsequently improved or altered), normal wear and tear excepted.

Such payment shall be made by Tenant to Landlord not later than thirty (30) days following date on which Landlord provides Tenant with written evidence of such tax liability by ordinary mail. If the final year of the lease fails to coincide with the tax year, then the amount due shall be prorated for the number of months of the Lease term during the year. This obligation shall survive the termination or expiration of this Lease, and if this Lease shall expire prior to the receipt of the current year’s tax or assessment notice, Landlord shall require Tenant to deposit an amount with the Landlord based upon the prior year’s tax or assessment increase. This amount shall be due upon delivery of written notice via ordinary mail from Landlord at any time prior to the expiration or termination of this Lease. An appropriate adjustment will
