9. Vacating Removed Premises . As of the Space Reduction Date, the Removed Premises shall no longer be part of the Premises, and all duties, obligations, rights and benefits of Landlord and Tenant as to the Removed Premises will terminate; excepting, however, for any duties or obligations of Tenant arising prior to the Space Reduction Date or which expressly survive the termination or expiration of the Lease, which duties and obligations shall continue until fulfilled. Tenant shall vacate the Removed Premises on or before the Space Reduction Date and shall deliver same to Landlord in accordance with Paragraph 23(b) of the Lease. Notwithstanding the foregoing, however, Tenant may remain in occupancy of the 4 ^th floor of the Premises (or, if Landlord leases such space to a third party, alternative space in the Building designated by Landlord) until the earlier of March 31, 2015, or Tenant’s completion of alterations to the 1 ^st floor portion of the Premises, and in such event, all provisions of the Lease other than the obligation to pay rent or additional rent shall apply to such 4 ^th floor portion of the Premises (or alternative space, if applicable) until Tenant vacates same.

10. Base Year . Prior to the Space Reduction Date, Landlord and Tenant acknowledge that the Base Year for Direct Operating Expenses in the Lease shall continue to be calendar year 2003. Commencing as of the Space Reduction Date, Landlord and Tenant acknowledge that the Base Year for Direct Operating Expenses in the Lease shall be calendar year 2015. Notwithstanding any provision in the Lease to the contrary, for purposes of calculating the Operating Expenses for any given calendar year, the amount, if any, by which Controllable Expenses (as defined in the Lease) exceed by more than five percent (5%) the amount of Controllable Expenses in the immediately preceding calendar year (on a cumulative, annualized basis) shall not be included in Operating Expenses for such calendar year.

11. Improvements . Landlord shall perform certain work (the “Tenant Improvements”) to the Premises in accordance with the Work Letter Agreement set forth in Exhibit “A” attached hereto and made a part hereof (the “Work Letter Agreement”). The taking of possession by Tenant shall be deemed conclusively to establish that the Premises are in a good and satisfactory condition as of when possession is so taken.

12. Renewal Option . Provided Tenant is not in default and as long as Tenant is still in occupancy of the Premises, Tenant shall have one (1) option to renew this Lease of the entire Premises for an additional five (5) year term provided Tenant gives one hundred eighty (180) days’ prior written notice to Landlord of Tenant’s intent to renew. The rental rate for the renewal term shall be at the then current Building market rate. As used herein, “Building market rate” shall have the meaning provided in the Special Stipulation 3 of Exhibit “E” to the Lease, and to the extent that there shall be any disagreement between Landlord and Tenant of the Building market rate, such disagreement shall be resolved in the manner described in Special Stipulation 3 of Exhibit “E” to the Lease. All other rights or options to renew set forth in the Lease, if any, are hereby deleted in their entirety and shall be of no further force or effect.

13. Right of First Refusal . Provided Tenant is not in default under the Lease beyond the expiration of any applicable notice and/or cure periods and at least thirty six (36) months remain in the term of the Lease, Tenant shall have an ongoing right of first refusal on space on the fourth (4 ^th ) floor of the Building as such space becomes available (the “Expansion Space”). The right of first refusal set forth in this Paragraph 13 shall be subject and subordinate to the existing rights of any existing tenants in the Building and to any existing renewals by existing tenants in any of such space. Upon receipt of written notice from Landlord that a third party has made a bona fide offer to lease any of the aforementioned Expansion Space, Tenant shall respond to Landlord within seven (7) business days whether it intends to lease such space. If Tenant indicates that it will not lease such space offered, or otherwise fails to notify

- 3 -

Landlord within such seven (7) business day period that Tenant will lease such space in accordance herewith, then Landlord may proceed to lease it to another party and Tenant shall have waived its right to lease such space at such time. If Tenant indicates that it will lease such space offered, then Tenant and Landlord shall execute an amendment to the Lease for such space within ten (10) days of Tenant notifying Landlord of its intention to lease such space. The lease of such Expansion Space by Tenant shall be on the terms set forth in such bona fide offer; provided, however, that if the term of the lease under such bona fide offer would commence on or before January 1, 2017, then such Expansion Space shall be leased at the rent (including escalations) and term then existing for the remaining Premises, and the amounts spent by Landlord for the tenant improvements provided for in the Work Letter Agreement (as reasonably established by Landlord) and other concessions contained in this Amendment with respect to the remaining Premises for the extension of the Lease term provided for herein shall be equitably and appropriately prorated, based upon such reduction in the term for such Expansion Space as compared to the eighty four (84) month extension of the Lease term provided for herein. For example, if Landlord spent $6.00 per rentable square foot for the tenant improvements provided for in the Work Letter Agreement, and if the term of the lease of the Expansion Space is 63 months, then the amount Landlord shall be required to contribute for tenant improvements for such Expansion Space shall be $6.00 per rentable square foot times 63/84, or $4.50 per rentable square foot of the Expansion Space. All other rights of first refusal, rights of first offer, or similar rights set forth in the Lease, including, but not limited to, the provisions of Special Stipulation 4 of Exhibit “E” of the Lease, are hereby deleted in their entirety and shall be of no further force or effect.

14. Brokers . Tenant represents that Tenant has not engaged or worked with any real estate brokers or agents other than Childress Klein Properties, Inc. and Cushman & Wakefield Georgia Inc. (local broker for Swearingen Realty Group LLC) (collectively, “Broker”) in connection with this Amendment. Tenant shall indemnify and hold harmless Landlord and Landlord’s agents from and against any and all claims for commissions or other compensation, and any liabilities, damages and costs relating thereto, that may be asserted by any person or entity other than Broker to the extent that Tenant has engaged such person or such claim results from any action of Tenant. Landlord represents that Landlord has not engaged or worked with any real estate brokers or agents other than Broker in connection with this Amendment. Landlord shall indemnify and hold harmless Tenant and Tenant’s agents from and against any and all claims for commissions or other compensation, and any liabilities, damages and costs relating thereto that may be asserted by any person or entity other than Broker to the extent that Landlord has engaged such person or such claim results from any action of Landlord. Landlord and Tenant agree that no commissions, fees or other compensation of any kind are due and payable to Broker in connection herewith.

15. Ratification . The Lease, as amended by this Amendment, is hereby ratified and confirmed, and each and every provision, covenant, condition, obligation, right and power contained in and under, or existing in connection with the Lease, as amended by this Amendment, shall continue in full force and effect. This Amendment is not intended to, and shall not be construed to, effect a novation, and, except as expressly provided in this Amendment, the Lease has not been modified, amended, canceled, terminated, surrendered, superseded or otherwise rendered of no force and effect. The Lease, as amended by this Amendment, is enforceable against the parties hereto in accordance with its terms.

16. Successors and Assigns . This Amendment shall bind and inure to the benefit of the parties hereto and their respective legal representatives, successors and assigns.

- 4 -

17. Counterparts . This Amendment may be executed in a number of identical counterparts, each of which for all purposes shall be deemed to be an original, and the Lease, as amended by this Amendment, shall collectively constitute but one agreement, fully binding upon, and enforceable against the parties hereto. The Lease and this Amendment shall be construed together as a single instrument.

When the final plans and specifications are approved by Landlord and Tenant, Landlord shall obtain a quotation, and shall submit the same to Tenant for approval as the price to be paid by Tenant to Landlord for said improvements. Upon written approval of such price by Tenant, Landlord and Tenant shall be deemed to have given final approval to the final plans and specifications on the basis of which the quotation was made and Landlord shall be authorized to proceed with the improvements of the Premises in accordance with such plans and specifications. If Tenant disapproves such price, or fails to approve or disapprove such price within five (5) days after submission thereof by Landlord, Landlord shall not be obligated to proceed with any improvement of the Premises until such time as Landlord and Tenant approve a price for Tenant’s work.
