ARTICLE 3.
RENT

     3.1 Base Rent. Tenant shall pay to Landlord, without notice or demand, in lawful money of the United States of America, at Landlord’s address set forth herein or at such other place or to such other person, firm or corporation as Landlord, from time to time, may designate in writing, Base Rent for each Lease Year during the Term of this Lease in an annual amount equal to $18.21 multiplied by the Thirty-Two Thousand (32,000) rentable square feet within the Leased Premises, and such amount shall be adjusted from time to time under the terms of this Lease. The annual Base Rent, which for the first Lease Year shall be Five-Hundred Eighty-Two Thousand, Seven-Hundred and Twenty and 00/100 Dollars ($582,720.00), shall be due and payable in twelve (12) equal monthly installments in the amount of Forty-Eight Thousand, Five-Hundred and Sixty and 00/100 Dollars ($48,560.00) each, payable in advance, beginning on the Commencement Date and continuing on the first day of each successive calendar month thereafter during the Term of this Lease. If any payment of Rent owing by Tenant to Landlord after the Commencement Date shall not be paid within five (5) days of the date when due, such unpaid amount shall be considered delinquent, and shall (i) be assessed a late fee in the amount of five percent (5%) of the unpaid amount, and (ii) bear interest at the Overdue Rate from the date such Rent payment was due to the date of actual payment.

     3.2 Adjustments to Base Rent. Landlord and Tenant agree that Base Rent payable under this Lease in accordance with Section 3.1 shall be subject to adjustment as set forth in this Section 3.2. Beginning with the second Lease Year, Base Rent shall be adjusted to reflect changes year to year in the Consumer Price Index (“CPI”) as set forth below. The basis for computing the CPI adjustment shall be the unadjusted Consumer Price Index for all Urban Consumers - all Items (1982-84=100) published by the Bureau of Labor Statistics of the United States Department of Labor (the “Index"). The Index for the third calendar month preceding the

beginning of the second Lease Year shall be the “Base Index Number.” The Index for the same month in the year of the applicable Adjustment Date shall be the “Current Index Number.” On each anniversary of the Commencement Date during the Term of this Lease (each such date an “Adjustment Date"), Base Rent shall be adjusted as follows (a) by an increase of three percent (3%) of the then current Base Rent or (b) if larger, by adjustment to reflect the increase in the CPI over the preceding Lease Year, not to exceed five percent (5%). If Base Rent is to be increased pursuant to clause (b), the new Base Rent shall be the product obtained by multiplying the Base Rent then in effect (the “Initial Base Rent”) by a fraction the numerator of which is equal to the Current Index Number and the denominator of which is equal to the Base Index Number. If the Index is not in existence at the time of such determination, the parties shall use an equivalent price index as is published by a comparable governmental agency in lieu of the Index or a mutually acceptable similar price index as published by a non-governmental agency.

     3.3 Triple Net Lease. This is a triple net lease, except as expressly modified by the terms and conditions of this Lease. With the exception of those items in Section 4.5 of this Lease, the Rent shall be paid absolutely net to Landlord, so that this Lease shall yield to Landlord the full amount of the installments of Base Rent and the payments of Additional Rent, as hereinafter defined, throughout the entire Term. The covenant to pay Rent as set forth in this Lease is independent of the covenants of Landlord hereunder. Tenant shall have no right of offset, deduction, abatement, recoupment or charge under this Lease and shall pay all Rent as and when due without any deduction whatsoever.

ARTICLE 4.
COSTS PAID BY TENANT

     4.1 Additional Rent; In addition to the Base Rent as set forth in Article 3 herein, Tenant shall pay Landlord “Additional Rent,” which term shall be defined to include, but not be limited to, the following:

          (a) All Operating Costs (as defined in Section 4.4) associated exclusively with Leased Premises;

          (b) Tenant’s Proportionate Share (as defined in Section 4.2) of Operating Costs for the CSLSC, the Land and the Common Areas, and which are not exclusively associated with a specific building within the CSLSC;

          (c) any sum owed for separately metered utilities, if any, including, without limitation, electricity, gas and telephone and data services;

          (d) to the extent paid by Landlord, all charges for insurance coverage required to be maintained pursuant to Article 12 hereof during the Term of this Lease; and

          (e) any other sums owed by Tenant pursuant to the terms of this Lease or otherwise arising in connection with Tenant’s occupancy of the Leased Premises.

     Any other operating costs or expenses related to Tenant’s use and occupancy of the Leased Premises that are paid directly by Tenant shall not be included in Additional Rent and Landlord/Building Management shall not be responsible for any such services or other obligations, of any kind whatsoever, related to these items.

     If Landlord subdivides and legally partitions the parcel of Land associated with planned building B of the CSLSC, Tenant’s Proportionate Share of Operating Costs shall not include any taxes or site maintenance for that subdivided and legally partitioned unimproved parcel of the Land until such time improvements commence for the development and construction of building B.

     For purposes of this Lease, Base Rent and Additional Rent shall hereinafter be collectively referred to as “Rent.”

     4.2 Proportionate Share. “Tenant’s Proportionate Share” shall mean the Rentable Square Footage divided by the CSLSC Total Square Footage.

     As and when the Building shall become part of or shall include a complex or group of buildings or structures collectively owned, leased or managed by or on behalf of Landlord or any of its affiliates, Landlord may allocate among the buildings within the complex or group of buildings those categories of Operating Costs which relate to any facilities which are for the common use or benefit of the complex or group of buildings, among such buildings in accordance with sound accounting and management principles and Section 4.1(b). Such common use or benefit facilities shall include, but shall not necessarily be limited to, parking facilities and driveways, sidewalks, connecting bridges and corridors, and other public areas that are not part of a particular building within the complex or group, all of which are maintained for the common benefit and use of buildings within the complex or group.

     4.3 Payment of Additional Rent. Tenant shall be responsible for and shall pay the Additional Rent for all calendar years during the term of this Lease.

          (a) Prior to the beginning of each calendar year during the Term (or within thirty days of the execution of this Lease for 2007), Landlord shall furnish Tenant with a statement of Landlord’s good-faith estimate of the Additional Rent for such calendar year. By the first day of each month thereafter during such calendar year, in addition to Base Rent due hereunder at such time, Tenant shall pay a monthly installment equal to 1/12th of the Additional Rent as estimated and set forth in such statement, if any, for such calendar year. If Landlord fails to deliver such statement prior to January 1 of the applicable year, Tenant shall pay 1/12th of the Additional Rent for the prior year, if any, until such statement is received. If Landlord furnishes Tenant such a statement, to the extent the new estimate is greater than or less than the estimates paid to date for such calendar year, a lump sum payment or credit shall be made in the next monthly payment to adjust for such differential and, thereafter, Tenant shall pay 1/12th of the Additional Rent as set forth in the new estimate.

          (b) Within thirty (30) days after the end of each calendar year during the Term, Landlord shall furnish to Tenant a statement of actual Additional Rent for the previous

calendar year (provided Landlord’s right to collect the Additional Rent shall not be affected if Landlord fails to deliver such statement within such thirty (30) day period). Such statement of actual Additional Rent shall include a detailed itemized monthly summary of Additional Rent charges incurred during each month in sufficient detail to enable Tenant to understand to what each charge relates. A lump sum payment (which payment shall be considered a payment of rent for all purposes) will be made by Tenant, within thirty (30) days of the delivery of that statement, equal to the excess, if any, of the actual amount of the Additional Rent over all amounts paid by Tenant hereunder with respect to the Additional Rent for the preceding calendar year. If the amount of the Additional Rent is less than the estimated amounts paid by Tenant hereunder with respect to the Additional Rent for such calendar year, Landlord shall apply the difference (the “Overage”) to the next accruing installment of Rent due hereunder or, if necessary, subsequently accruing installments of Rent until the entire Overage amount is credited; provided that if the term of this Lease has expired at the time Landlord’s Statement is delivered, Landlord shall refund the amount of any Overage within 30 days of the issuance of Landlord’s Statement.

          (c) In the event the amount of Additional Rent for the final calendar year of the Term is not calculated and submitted until after the expiration of the Term, then Tenant’s obligation to pay the same and Landlord’s obligation to refund any Overage shall survive the expiration or termination of this Lease. Accordingly, in addition to other remedies available to Landlord hereunder and provided that Landlord provides Tenant with the statement of actual Additional Rent within sixty (60) days of the expiration of the Term, Landlord shall have the right to continue to hold without interest Tenant’s Security Deposit, if any, following expiration of the Term until the Additional Rent has been paid in full, unless an alternative security (letter of credit or otherwise) is furnished to the satisfaction of Landlord. The Additional Rent for the calendar years in which the Term commences and ends, if any, shall be prorated on the basis of the number of days of the Term within each such calendar year.

          (d) Notwithstanding Sections 4.3(a) — (c), Landlord may alternatively elect to invoice Tenant on a monthly basis for all actual Additional Rent as the expenses are incurred. Tenant shall pay such invoices within thirty (30) days of receipt thereof.

          (e) Landlord shall maintain, and shall ensure that any Management Company maintains, complete and accurate records sufficient to enable accurate calculation of Additional Rent due under this Lease. Once a calendar year, Tenant shall have the right to select a certified public accountant reasonably acceptable to Landlord to inspect, on not less than fifteen (15) business days prior written notice and during regular business hours, the records of Landlord and/or any Management Company necessary to verify the Additional Rent payments due pursuant to this Lease. Such accountant must execute a nondisclosure agreement reasonably satisfactory to Landlord prior to any access to records. The entire cost for such inspection shall be borne by Tenant unless there is a discrepancy of greater than, or equal to, ten percent (10%) in Landlord’s favor, in which case Landlord shall bear Tenant’s external auditors costs for the inspection. Records shall be preserved by Landlord and any Management Company for seven (7) years for inspection by Tenant.

     4.4 Operating Costs Defined. “Operating Costs” shall mean all amounts paid or payable, whether by Landlord or by others on behalf of Landlord, arising out of the ownership,

management, maintenance, operation, repair, replacement and administration of the CSLSC, including, without limitation:

          (k) costs incurred by Landlord to conduct any environmental tests required by municipal, county, state or federal law, including administrative agencies, or by Landlord;

No interest shall be paid upon the Security Deposit nor shall Landlord be required to maintain the deposit in a segregated account, unless required by applicable law in which event Landlord will comply with such legal requirement. The Security Deposit shall not be construed as prepaid rent. In the event that Tenant shall default in the full and faithful performance of any of the terms hereof, then Landlord may, without notice, either retain the Security Deposit as liquidated damages, or Landlord may retain the same and apply it toward any damages sustained by Landlord, including but not limited to actual, consequential or other direct or indirect damages sustained by the Landlord by reason of the default of Tenant, including but not limited to any past due rent.

In the event of a sale of the Leased Premises or all or any portion of the Building, Landlord shall have the right to transfer the Security Deposit to the buyer, and Landlord shall thereupon be relieved of all obligations to return the Security Deposit to Tenant, and Tenant agrees to look solely to the buyer for the return of the Security Deposit. If Tenant fully and faithfully complies with all of the terms hereof, the Security Deposit or any balance thereof shall be returned to Tenant within sixty (60) days after expiration of this Lease, including any renewal thereof.

          (d) Tenant will, upon the expiration or prior termination of this Lease, vacate and surrender the Leased Premises to Landlord, and solely at Landlord’s discretion: (i) in the same physical condition in which the Leased Premises was originally received from Landlord on the Commencement Date, except for ordinary wear and tear; or (ii) in good condition suitable for the commercial use which is the same as or similar to the Tenant’s Primary Intended Use as defined herein; unless otherwise agreed upon in writing by and between the parties.

ARTICLE 9.
ALTERATIONS AND ADDITIONS

     9.1 Construction of Capital Additions to the Leased Premises. Schedule 9.1 sets forth the capital additions to the Building heretofore made by Tenant, the date such capital additions were completed and the amount expended by Tenant in making such capital additions. Tenant shall supplement Schedule 9.1 from time to time as additional capital additions to the Building are made pursuant to this Article 9, and any such supplement shall be incorporated herein by reference and shall be deemed to be a part of this Lease as if fully set forth herein. Tenant shall not make or permit to be made any additional capital additions to the Leased Premises, unless and until Tenant shall have caused plans and specifications therefor to have been prepared, at Tenant’s expense, by a licensed architect and shall have obtained Landlord’s written approval both prior to commencement of construction and upon completion thereof, which approvals shall not be unreasonably withheld, conditioned or delayed. Landlord shall, with reasonable promptness, advise Tenant of its approval or disapproval of the proposed capital addition. If Tenant’s proposed capital addition is not approved, then Landlord shall specify such alternative conditions, if any, upon which Landlord might approve such capital addition. Tenant shall cause the work on any capital additions permitted to be made hereunder to be performed, at its expense, promptly and in a workmanlike manner by a licensed general contractor and in compliance with all applicable Legal Requirements, Insurance Requirements and the standards set forth in this Lease. Unless otherwise specifically agreed in writing by Landlord, any capital additions permitted to be made to the Leased Premises hereunder shall be at the sole cost and expense of Tenant. Each and every such capital addition shall become a part of the Leased Premises subject to the terms, conditions, covenants and agreements of this Lease. All materials which are scrapped or removed in connection with the making of every such capital addition shall be removed from the Leased Premises at Tenant’s expense and shall be disposed of by Tenant in accordance with all applicable laws, including all Hazardous Materials Laws.

     9.2 Remodeling and Non-Capital Additions. Subject to the limitations regarding capital additions set forth in Section 9.1 above, Tenant shall have the right to make any and all nonstructural, cosmetic additions, modifications or improvements to the Leased Premises which do not modify the Building or require approval from any governmental agency, from time to time, as may reasonably be necessary for its uses and purposes and to permit the Tenant to comply fully with its obligations set forth in this Lease; provided that such action will be undertaken expeditiously, in a workmanlike manner and will not significantly alter the character or purpose or detract from the value or operating efficiency of the Leased Premises or adversely affect the ability of the Tenant to comply with the provisions of this Lease. All such additions, modifications and improvements shall be included as part of the Leased Premises subject to the terms, conditions, covenants and agreements of this Lease.

     9.3 Tenant Rent Credit. In consideration of Tenant’s execution of this Lease, Landlord shall provide Tenant with a credit to be applied against Rent in the amount of One-Hundred and Sixty Thousand and No/100 Dollars ($160,000.00) (which is equal to Five and No/100 Dollars ($5.00) multiplied by the Rentable Square Feet) (the “Tenant Rent Credit”). Tenant may apply the Tenant Rent Credit, or any portion thereof remaining, after the fourth year of this lease, by giving Landlord written notice of its intent to do so sixty (60) days before the date on which Rent is due under this Lease.

     9.4 Tenant Improvement Work. Tenant shall contract for and pay the cost of any and all improvements to the Leased Premises related to Tenant’s use thereof (the “Tenant Improvement Work”). Throughout the process of preparing the plans for the Tenant Improvement Work and obtaining any necessary governmental permits and approvals, each party shall act diligently and in good faith and shall cooperate with the other and with governmental agencies in whatever manner may be reasonably required. Tenant acknowledges and agrees that Landlord reserves the right, without Tenant’s consent and without liability to Tenant, to make any modifications, changes or omissions to the plans required by any governmental or quasi-governmental authority or utility. Tenant acknowledges that interior finishes such as brick, wood, wood grain, carpeting, paint, cabinets, cultured marble, tile, mica, and the like, are subject to shading and gradation and may vary from samples, models or color charts, and from piece to piece, and Landlord will not be liable for such variation.

     9.5 Change Orders and Extras. Any change orders or extras desired by Tenant and not included or shown in the original plans approved by Landlord must be further agreed to by Landlord in writing. Tenant will pay the cost of any change or extra at such time as Tenant is instructed by Landlord to pay same.

     9.6 Tenant Capital Additions. Upon the consent of Tenant, other tenants of the CSLSC may utilize any capital addition listed in Schedule 9.1. Landlord shall provide Tenant written notice thereof setting forth which capital addition would be utilized and the anticipated extent of such usage. Tenant’s consent thereof shall not be unreasonably withheld provided there is adequate capacity to accommodate such other tenant. During the Initial Term of this Lease, Tenant shall be compensated for such use in the form of payment by Landlord directly or the tenant(s) utilizing the capital addition. The payment shall be based upon the extent of said use and upon the then remaining unamortized portion of the improvement, and shall be agreed upon prior to Tenant providing its consent to allowing the access to the capital addition.

ARTICLE 10.
NO LIENS

     Subject to the provisions of Article 11 relating to permitted contests, Tenant will not directly or indirectly create or suffer to exist and will promptly discharge at its expense any lien, encumbrance, attachment, title retention agreement or claim upon the Leased Premises or any attachment, levy, claim or encumbrance in respect of the Rent, not including, however, (a) this Lease, (b) the matters, if any, set forth in Schedule 10 attached hereto [intentionally blank], (c) restrictions, liens and other encumbrances which are consented to in writing by Landlord, (d) leases to other tenants in the Building and subleases permitted by Article 20, (e) liens for

ARTICLE 11.
PERMITTED CONTESTS

     Tenant, after ten (10) days’ prior written notice to Landlord, on its own or on Landlord’s behalf (or in Landlord’s name), but at Tenant’s expense, may contest, protest or appeal by appropriate legal or administrative proceedings conducted in good faith and with due diligence, the amount, determination, validity, assessment, imposition or application, in whole or in part, of any Imposition, Legal Requirement, Insurance Requirement, lien, attachment, levy, encumbrance, charge or claim (collectively “Charge”) which is required to be paid, discharged, observed or complied with by Tenant under this Lease; provided that (a) in the case of an unpaid Charge, the commencement and continuation of such proceedings or the posting of a bond as may be permitted by applicable law shall suspend the collection thereof from Landlord and from the Leased Premises; (b) neither the Leased Premises nor any Rent therefrom nor any part thereof or interest therein would be in any immediate danger of being sold, forfeited, attached or lost; (c) Landlord would not be in any immediate danger of civil or criminal liability for failure to comply therewith pending the outcome of such proceedings; (d) in the case of an Insurance Requirement, the coverage required by Article 12 shall be maintained; and (e) if such contest be finally resolved against Landlord or Tenant, Tenant shall promptly pay any amount required to be paid, including without limitation interest and penalties accrued thereon, or otherwise comply with the applicable Charge. Landlord, at Tenant’s expense, shall execute and deliver to Tenant such authorizations and other documents as may reasonably be required in any such action and, if reasonably requested by Tenant or if Landlord so desires and then at its own expense, Landlord shall join as a party therein. Landlord will cooperate fully and in good faith with Tenant in such contest and shall do all things reasonably requested by Tenant in connection with any such action. Tenant shall indemnify and save Landlord harmless against any liability, cost or expense of any kind that may be imposed upon Landlord in connection with any such action and any damages resulting therefrom.

ARTICLE 12.
INSURANCE

     12.1 Tenant’s Insurance. Tenant shall keep in full force and effect throughout the Lease Term a policy or policies of commercial property insurance, issued on an “all risks” basis insuring the full replacement cost of its furniture, equipment, supplies and all other personal property owned, leased, held or possessed by it and located upon the Building, and the capital additions and tenant improvements made to the Leased Premises by Tenant (with a replacement

cost endorsement sufficient to prevent Tenant from becoming a co-insurer). Tenant shall also procure at its expense and maintain throughout the Lease Term a policy or policies of commercial general liability insurance, and workers’ compensation insurance as required by applicable law, including but not limited to, insurance for assumed or contractual liability under this Lease, all written on an occurrence basis and insuring Tenant, Landlord, any mortgagee, and any other person with an insurable interest designated by Landlord, against any and all liability for injury to or death of a person or persons and for damage to property occasioned by or arising out of any occurrence on the Building, or arising out of the condition, use or occupancy of the Building, or in any way occasioned by or arising out of the activities of Tenant, its agents, contractors, employees, guests or licensees in the Building, or other portions of the Building or the CSLSC. The limits of such liability policies shall be in combined single limits for both damage to property and personal injury and in amounts not less than Three Million Dollars ($3,000,000.00) for each occurrence. Such liability insurance shall, in addition, extend to any liability of Tenant arising out of the indemnities provided for in this Lease. Tenant shall also require any contractor performing work on the Building for Tenant to carry and maintain, at no expense to Landlord, non-deductible commercial general liability insurance, including but not limited to, contractor’s liability coverage, contractual liability coverage, completed operations coverage, broad form property damage endorsement and contractor’s protection liability coverage in such amounts and with such companies as Landlord shall approve. All insurance policies procured and maintained by Tenant pursuant to this Section 12.1 shall name Landlord and any additional parties designated by Landlord as additional insured, shall be carried with companies licensed to do business in the State of Tennessee reasonably satisfactory to Landlord, and shall be non-cancelable and not subject to material change except after thirty (30) days’ written notice to Landlord. Such policies or duly executed certificates of insurance with respect thereto, accompanied by proof of payment of the premium therefor, shall be delivered to Landlord prior to the Commencement Date, and renewals of such policies shall be delivered to Landlord at least thirty (30) days prior to the expiration of each respective policy term.

     12.2 Landlord’s Insurance. During the Term, Landlord agrees to maintain (a) “all risk” full replacement cost property insurance on the Building, exclusive of improvements made by Tenant in excess of the initial Tenant Improvements, in an amount sufficient to prevent Landlord from being deemed a co-insurer of the risks insured under the policy, which shall include customary rent loss insurance covering loss of rents for a period of at least one year, and which shall include, as and to the extent customarily included by prudent owners of comparable first class office buildings in Brentwood, Tennessee, boiler and machinery and electrical apparatus coverage; and (b) commercial general liability insurance, including but not limited to, insurance assumed or contractual liability under this Lease, in an amount not less than Three Million and No/100 Dollars ($3,000,000.00) combined single limit per occurrence (which may be a combination of primary and umbrella coverage’s). Landlord shall furnish to Tenant certificates or other evidence of insurance from the insurer, or, if not available from the insurer, then from the insurance agent, evidencing such coverage at the time this Lease is executed and, at Tenant’s request, within thirty (30) days after any policy is renewed, replaced or changed.

     12.3 Waiver of Subrogation. Landlord and Tenant shall each have included in all policies of commercial property insurance, business interruption, rent loss and other insurance respectively obtained by them covering the Building, the Building and any contents therein, a

waiver by the insurer of all right of subrogation against the other party hereto in connection with any loss or damage thereby insured against. Any additional premium for such waiver shall be paid by the primary insured. To the full extent permitted by law, Landlord and Tenant each waives all right of recovery against the other for, and agrees to release the other from liability for, loss or damage to the extent such loss or damage is actually covered by valid and collectible insurance in effect at the time of such loss or damage or would be covered by the insurance required to be maintained under this Lease by the party seeking recovery.

     12.4 Form of Insurance. All of the policies of insurance referred to in this Lease shall be written by companies reasonably acceptable to Landlord, which acceptance shall not be unreasonably withheld, conditioned or delayed, and authorized to do insurance business in the State of Tennessee and shall name the Landlord as loss payee or an additional insured, as the case may be. Tenant will, upon request by Landlord; provide Landlord with certificates of insurance evidencing the policies required hereby. Each insurer mentioned in this Article 12 shall agree, by endorsement on the policy or policies issued by it, or by independent instrument furnished to Landlord, that it will give to Landlord thirty (30) days’ written notice before the policy or policies, in question shall be allowed to expire or canceled.

     12.5 Changes in Limits. In the event that Landlord shall, at anytime, reasonably and in good faith believe the limits of the personal injury, property damage or general public liability insurance then carried to be insufficient, the parties shall endeavor to agree on the proper and reasonable limits for such insurance to be carried and such insurance shall thereafter be carried within the new limits until further change pursuant to the provisions of this Section. If the parties shall be unable to agree thereon, the proper and reasonable limits for such insurance shall be determined by an impartial third party selected by the parties, who is experienced in the commercial insurance industry. Such re-determination, whether made by the parties or arbitration, shall be made no more frequently than every two (2) years

     12.6 Blanket Policy. Notwithstanding anything to the contrary contained in this Article 12 Tenant’s obligations to carry the insurance provided for herein may be brought within the coverage of a so-called blanket policy or policies of insurance carried and maintained by Tenant; provided that the coverage afforded Landlord will not be reduced or diminished or otherwise be different from that which would exist under separate policies or policies issued by insurance companies meeting all other requirements of this Lease.

ARTICLE 13.
CASUALTY LOSS

     13.1 Disposition of Insurance Proceeds. All proceeds payable by reason of any loss or damage to the Leased Premises, or any portion thereof, and insured under any policy of insurance required by Article 12 of this Lease (exclusive, however, of any proceeds of insurance covering Tenant’s equipment used in its business or other business related personal property and exclusive of proceeds from business interruption insurance), shall be paid to Landlord, free from any claim or right of Tenant, and shall be used solely and made available for reconstruction or repair, as the case may be, of any damage to or destruction of the Leased Premises, or any portion thereof, and shall be paid out from time to time for the reasonable cost of such

reconstruction or repair in accordance with this Article 13. Any excess proceeds of insurance remaining after the completion of the restoration or reconstruction of the Leased Premises shall be the property of Landlord free and clear, with Tenant being entitled to its pro-rata share of such excess, upon completion of any such repair and restoration, except as otherwise specifically provided below in this Article 13. In the event Landlord is not required to repair and restore the Leased Premises as a result of the termination of this Lease, then all such insurance proceeds shall be retained by and shall belong to Landlord, free from any claim or right of Tenant, except however, Tenant shall be entitled to receive a portion of such proceeds equal to the unamortized costs of the capital additions which were paid directly by Tenant, based upon the Term of the Lease as stated herein, and the remaining portion of the Lease, had the Lease not been terminated. All salvage resulting from any risk covered by insurance shall belong to Tenant.

     13.2 Reconstruction in the Event of Damage or Destruction Covered by Insurance.

          (a) If during the Lease Term, the Leased Premises are totally or partially damaged or destroyed from a risk covered by the types of insurance described in Article 12 and the Leased Premises is thereby rendered Unsuitable for its Primary Intended Use, Landlord shall, to the extent that insurance proceeds have been made available therefor, within ninety (90) days of the occurrence (but only if the necessary insurance proceeds have been received by Landlord), commence the restoration process for the Leased Premises so damaged or destroyed to substantially the same (or better) condition as their condition immediately prior to such damage or destruction, and diligently prosecute the same to completion; provided, however, nothing in this Lease shall be construed to require Landlord to expend in connection with the repair or reconstruction of the Leased Premises an amount greater than the actual insurance proceeds made available to Landlord. Such damage or destruction shall not terminate this Lease. Only an agreement in writing between Tenant and Landlord to terminate this Lease and/or Landlord’s inability to obtain all necessary government approvals, within a reasonable time, including building permits, licenses, and/or conditional use permits after diligent efforts to do so, shall terminate this Lease. Landlord shall give Tenant written notice thereof, and this Lease shall terminate as of the later of (a) the first day of the calendar month following the date of delivery of the notice to Tenant or (b) fifteen (15) Business Days after the date of delivery of the notice to Tenant. Tenant may elect, at any time subsequent to such damage or destruction, upon Landlord’s prior written consent which shall not be unreasonably withheld, to commence such restoration at Tenant’s own expense, and shall diligently prosecute the same to completion. If Tenant elects to undertake the restoration of the Leased Premises so damaged or destroyed it shall restore the Leased Premises to substantially the same (or better) condition as the condition immediately prior to such damage or destruction. Tenant shall have the right to be reimbursed from the insurance proceeds, for its external expenses (i.e., exclusive of general overhead such as salaries for its employees) related to such restoration.

          (b) If during the Lease Term, the Leased Premises is totally or partially destroyed from a risk covered by the types of insurance described in Article 12, but the Leased Premises is not thereby rendered Unsuitable for its Primary Intended Use, within ninety (90) days of the occurrence (if the necessary funds have been received by Landlord), Landlord shall commence the restoration process to restore the Leased Premises so damaged or destroyed to

substantially the same condition as existed immediately before the damage or destruction and diligently prosecute the same to completion. Such damage or destruction shall not terminate this Lease. Tenant may elect, at any time subsequent to such damage or destruction, upon Landlord’s prior written consent which shall not be unreasonably withheld, to commence such restoration at Tenant’s own expense, and shall diligently prosecute the same to completion. If Tenant elects to undertake the restoration of the Leased Premises so damaged or destroyed it shall restore the Leased Premises to substantially the same (or better) condition as the condition immediately prior to such damage or destruction. Tenant shall have the right to be reimbursed from the insurance proceeds, for its external expenses related to such restoration.

     13.3 Tenant’s Personal Property. All insurance proceeds payable by reason of any loss of or damage to any of Tenant’s Personal Property shall be paid and belong to Tenant. Landlord shall have no obligation to replace any of Tenant’s Personal Property.

     13.4 Restoration of Improvements and Additions. If Landlord is required to restore the Leased Premises as provided in Section 13.2 above, Landlord shall also restore all capital additions made by Tenant, but only to the extent that insurance proceeds are made available to Landlord therefor.

     13.5 Option for Abatement of Rent. In the event that this Lease is not terminated pursuant to this Article 13, then this Lease shall remain in full force and effect during the period of restoration and construction and Tenant’s obligation to make payments of Rent and to pay all other charges required by this Lease shall remain unabated, unless the Tenant has in force on the date of such damage or destruction rent or rental value insurance in which event the Rent payable hereunder shall be abated to the extent, and for such period, which Rent is being paid to Landlord on behalf of Tenant by the insurer. If this Lease shall terminate pursuant to this Article 13, then Rent and all other charges required by this Lease shall be abated and apportioned as of the date of such damage or destruction.

     13.6 Standard of Work. All work commenced by Landlord under this Article 13 to repair or restore the Leased Premises shall be diligently prosecuted to completion in a good and workmanlike manner, using as near as practical the same materials as in the original construction of the Leased Premises requiring repair or restoration.

ARTICLE 14.
CONDEMNATION

     14.1 Parties’ Rights and Obligations. If during the Term there is any Taking of all or any part of the Leased Premises or any interest in this Lease by Condemnation, the rights and obligations of the parties shall be determined by this Article 14.

     14.2 Total Taking. If there is a Taking of all of the Leased Premises by Condemnation, this Lease shall terminate on the date of Taking, and the Rent and all additional charges paid or payable hereunder shall be apportioned and paid to the date of Taking.

     14.3 Partial Taking. If title to the fee of less than the whole of the Leased Premises shall be so taken or condemned, which nevertheless renders the Leased Premises Unsuitable for Its Primary Intended Use, Tenant and Landlord shall each have the option, exercisable by written notice to the other, at any time within thirty (30) days after the taking of possession by, or the date of vesting of title in, such Condemnor, whichever first occurs, to terminate this Lease as of the Taking. Upon such date so determined, if such notice has been given, this Lease shall thereupon cease and terminate as to such Leased Premises. All Rent and other charges paid or payable by Tenant hereunder shall be apportioned as of the date the Lease shall have been so terminated. If there is a Taking of a portion of the Leased Premises by Condemnation such that the Leased Premises is not thereby rendered Unsuitable for Its Primary Intended Use, the Landlord at its sole discretion may (a) terminate this Lease, or (b) have this Lease remain in effect and Landlord shall restore the untaken portion of the Building shell in which the Leased Premises are located so that such Leased Premises shall constitute a complete architectural unit of the same general character and condition (as nearly as may be possible under the circumstances) as the Leased Premises existing immediately prior to such Condemnation or Taking. Landlord shall commence the restoration process for the Leased Premises within ninety (90) days of the partial Taking, if the necessary funds have been received by the Landlord, and shall diligently prosecute the restoration to completion. Tenant may elect, at any time subsequent to such Condemnation or Taking, upon Landlord’s prior written consent which shall not be unreasonably withheld, to commence such restoration at Tenant’s own expense, and shall diligently prosecute the same to completion. If Tenant elects to undertake the restoration of the Leased Premises so Condemned or Taken, it shall restore the untaken portion of the Building shell in which the Leased Premises are located so that such Leased Premises shall constitute a complete architectural unit of the same general character and condition (as nearly as may be possible under the circumstances) as the Leased Premises existing immediately prior to such Condemnation or Taking. Tenant shall have the right to be reimbursed from the Award for such Condemnation or Taking, for its external expenses related to such restoration.

     14.4 Award Distribution. The entire Award for any Taking, whether total or partial, shall belong to and be paid to Landlord, except that, if this Lease is terminated hereinunder, Tenant shall be entitled to receive a portion of such proceeds equal to the unamortized costs of the capital additions which were paid directly by Tenant, based upon the Term of the Lease as stated herein, and the remaining portion of the Lease, had the Lease not been terminated, and Tenant shall be entitled to any portion of the Awards as provided in Section 14.3.

     If the Leased Premises are restored, Landlord agrees that the necessary portion of the Award shall be used for such restoration. In any proceeding for any Taking for all or any part of the Leased Premises, Tenant shall have the right at Tenant’s cost and expense, to prove damages and receive an Award for damages to or Condemnation of its movable trade fixtures and personal property and for any moving and relocation expenses, or make a separate claim with the Condemnor for the same. Landlord and Tenant agree to cooperate with the other in the event of any Taking of all or any portion of the Leased Premises, so that each may receive the maximum Award, if any, to which they are respectively entitled under applicable law.

ARTICLE 15.
DEFAULT

     15.1 Events of Default. The occurrence of any one or more of the following events shall constitute an event of default (individually, an “Event of Default” and, collectively, “Events of Default”) hereunder:

          (a) if Tenant shall fail to make a payment of the Rent payable by Tenant under this Lease when the same becomes due and payable and each such failure continues for a period of five (5) Business Days after written notice from Landlord to Tenant, , or

          (b) if Tenant shall fail to observe or perform any other term, covenant or condition of this Lease on its part to be performed, and such failure is not cured by Tenant within a period of thirty (30) days after written notice thereof from Landlord, unless such failure cannot with due diligence be cured within a period of thirty (30) days, in which case such failure shall not be deemed to continue if Tenant proceeds promptly and with due diligence to cure the failure and diligently completes the curing thereof (as soon as reasonably possible), or

          (c) if Tenant shall:

               (i) admit in writing its or inability to pay debts generally as they become due,

               (ii) file a petition in bankruptcy or a petition to take advantage of any insolvency law,

               (iii) make an assignment for the benefit of its creditors,

               (iv) consent to the appointment of a receiver of itself or of the whole or any substantial part of its property, or

               (v) file a petition or answer seeking reorganization or arrangement under the Federal bankruptcy laws or any other applicable law or statute of the United States of America or any state thereof, or

          (d) If Tenant shall be finally liquidated or dissolved, or shall begin proceedings towards such liquidation or dissolution, or shall have filed against it a petition or other proceeding to cause it to be liquidated or dissolved and such proceeding is not dismissed within thirty (30) days thereafter.

     15.2 Remedies. If an Event of Default shall have occurred and be continuing past any applicable grace period, Landlord shall have the right, at its election, then or at any time thereafter, to pursue any one or more of the following remedies, in addition to any and all remedies which may be permitted by law or by other provisions of this Lease, without further notice or demand, except as hereinafter provided:

          (a) Without any notice or demand whatsoever, Landlord may take any one or more actions permissible at law to ensure performance by Tenant of Tenant’s covenants and obligations under this Lease. In this regard, it is agreed that if Tenant abandons or vacates the Leased Premises, Landlord may enter upon and take possession of such Leased Premises in order to protect it from deterioration and continue to demand from Tenant the monthly rentals and other charges provided in this Lease. Landlord shall use reasonable efforts to relet but shall have no absolute obligation to relet. If Landlord does, at its sole discretion, elect to relet the Leased Premises, such action by Landlord shall not be deemed as an acceptance of Tenant’s surrender of the Leased Premises unless Landlord expressly notifies Tenant of such acceptance in writing pursuant to subsection (b) of this Section 15.2, Tenant hereby acknowledging that Landlord shall otherwise be reletting as Tenant’s agent. It is further agreed in this regard that in the event of any Event of Default described in Section 15.1, Landlord shall have the right to enter upon the Leased Premises and do whatever Tenant is obligated to do under the terms of this Lease; and Tenant agrees to reimburse Landlord on demand for any reasonable expenses which Landlord may incur in thus effecting compliance with Tenant’s obligations under this Lease, and further agrees that Landlord shall not be liable for any damages resulting to the Tenant from such action provided that Landlord is not negligent.

          (b) Landlord may terminate this Lease by written notice to Tenant, in which event Tenant shall immediately surrender the Leased Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which Landlord may have for possession or arrearage in Rent (including any interest at the Overdue Rate which may have accrued thereon), enter upon and take possession of the Leased Premises, expel or remove Tenant and any other person who may be occupying the Leased Premises or any part thereof, and, at Landlord’s option, relet or operate the Leased Premises. In addition, Tenant agrees to pay to Landlord on demand the amount of all loss and damage which Landlord may suffer by reason of any termination effected pursuant to this subsection (b).

          (c) The rights and remedies of Landlord hereunder are cumulative, and pursuit of any of the above remedies shall not preclude pursuit of any other of the above remedies, any other remedies prescribed in other sections of this Lease, or any other remedies provided by law or equity. Forbearance by Landlord to enforce one or more of the remedies herein provided upon an Event of Default shall not be deemed or construed to constitute a waiver of such Event of Default.

     15.3 Additional Expenses. In addition to all payments required under this Lease, Tenant shall compensate Landlord for all reasonable expenses incurred by Landlord in repossessing the Leased Premises and all reasonable expenses incurred by Landlord in reletting (including without limitation attorney fees, repairs, remodeling, replacements, advertisements and brokerage fees).

     15.4 Application of Funds. All payments otherwise payable to Tenant, if any, which are received by Landlord under any of the provisions of this Lease during the existence or continuance of any Event of Default shall be applied to Tenant’s obligations in the order which Landlord may reasonably determine or as may be prescribed by the laws of the State of Tennessee.

     15.5 Attorneys’ Fees and Expenses. In the event it becomes necessary for Landlord to employ an attorney to collect the Rent or any other sums due or payable to Landlord hereunder, Tenant shall pay and reimburse Landlord for the reasonable attorney’s fees, costs and expenses, including court costs, incurred by Landlord in connection therewith. With regard to any other disputes hereunder or efforts to otherwise enforce the terms and provisions of this Lease or preserve, protect or defend the a party’s rights, interests or remedies hereunder, Landlord and Tenant agree that the prevailing party will pay and reimburse the other party, on demand therefor, the reasonable attorneys fees, costs and expenses, including court costs, incurred by the prevailing party in connection therewith.

ARTICLE 16.
LANDLORD’S RIGHT TO CURE

     If Tenant shall fail to make any payment, or to perform any act required to be made or performed under this Lease and to cure the same within the relevant time periods provided in Section 15.1, Landlord, without waiving or releasing any obligation or Event of Default, may (but shall be under no obligation to) make such payment or perform such act for the account and at the expense of Tenant, and may, to the extent permitted by law, enter upon the Leased Premises for such purpose and take all such action thereon as, in Landlord’s opinion, may be necessary or appropriate therefor. No such entry shall be deemed an eviction of Tenant. All sums so paid by Landlord, together with interest thereon (to the extent permitted by law) at the Overdue Rate from the date on which such sums or expenses are paid or incurred by Landlord, and all costs and expenses (including reasonable attorneys’ fees and expenses, in each case, to the extent permitted by law) so incurred shall be paid by Tenant to Landlord on demand. The obligations of Tenant and rights of Landlord contained in this Article shall survive the expiration or earlier termination of this Lease.

ARTICLE 17.
HOLDING OVER

     If Tenant shall for any reason remain in possession of the Leased Premises after the expiration of the Term or any earlier termination of the Term hereof, such possession shall be as a tenancy at will, during which time Base Rent shall be increased to two (2) times the Base Rent in effect at the time of the holdover and Tenant shall be obligated to continue to perform and observe all of the terms, covenants and conditions of this Lease and to continue its occupancy and use of the Leased Premises. Nothing contained herein shall constitute the consent, express or implied, of Landlord to the holding over of Tenant after the expiration or earlier termination of this Lease or a waiver of Landlord’s right of re-entry or any other right or remedy hereunder.

ARTICLE 18.
UNAVOIDABLE DELAY

     In the event that either Landlord or Tenant shall be delayed, hindered in, or prevented from the performance of any act required hereunder by reason of Unavoidable Delay, then the performance of such act shall be excused for the period of the delay; provided however, that the

party so delayed, hindered or prevented shall use its reasonable best efforts to remedy with all reasonable dispatch the Unavoidable Delay so delaying, hindering or preventing the party from performance to the extent such party is reasonably or practically able to do so, except that such party shall in no event be required to settle strikes, lock-outs or other disputes or disturbances by acceding to the demands of the opposing party or parties when such course is, in the judgment of such party, unfavorable to such party.

ARTICLE 19.
INDEMNIFICATION

     Notwithstanding the existence of any insurance provided for in Article 12, and without regard to the policy limits of any such insurance, Tenant will, except for the negligence or willful misconduct of Landlord or its agents or employees, protect, indemnify, save harmless and defend Landlord, its agents and employees, from and against any and all liabilities, obligations, claims, damages, penalties, causes of action, costs and expenses (including reasonable attorneys’ fees and expenses) imposed upon, suffered or incurred by, or asserted against Landlord by reason of, or arising out of or related to: (a) any accident, injury to or death of persons or loss to property occurring on or about the Leased Premises during the Lease Term or arising out of or related to the use and operation of the Leased Premises by Tenant or any business conducted thereon or therefrom by Tenant during the Lease Term, (b) any use, operation, permitted sublease or assignment, misuse, non-use, condition, maintenance or repair of the Leased Premises by Tenant during the Lease Term, (c) any Impositions (which are the obligations of Tenant to pay pursuant to the applicable provisions of this Lease), (d) any failure on the part of Tenant to perform or comply with any of the terms of this Lease, (e) the non-performance by Tenant during the Lease Term of any of the terms and provisions of any and all existing and future subleases of the Leased Premises to be performed by Tenant as landlord thereunder, and (f) the nonperformance of any contractual obligation, express or implied, assumed or undertaken by Tenant or any party in privity with Tenant with respect to the Leased Premises or any business or other activity carried on by Tenant with respect to the Leased Premises during the Term hereof.

     Notwithstanding the existence of any insurance provided for in Article 12, and without regard to the policy limits of any such insurance, Landlord will, except for the negligence or willful misconduct of Tenant or its agents or employees, protect, indemnify, save harmless and defend Tenant, its agents and employees, from and against any and all liabilities, obligations, claims, damages, penalties, causes of action, costs and expenses (including reasonable attorneys’ fees, and expenses) imposed upon, suffered or incurred by, or asserted against Tenant by reason of, or arising out of or related to: (a) any accident, injury to or death of persons or loss to property occurring on or about the Facility, exclusive of the Leased Premises, during the Lease Term or arising out of or related to the use and operation of the Facility by Landlord, exclusive of the Leased Premises during the Lease Term, (b) any use, operation, condition, maintenance or repair of the Facility exclusive of the Leased Premises by Tenant during the Lease Term, (c) any Impositions (which are the obligations of Landlord to pay pursuant to the applicable provisions of this Lease), (d) any failure on the part of Landlord to perform or comply with any of the terms of this Lease, and (f) the nonperformance of any contractual obligation, express or implied, assumed or undertaken by Landlord or any party in privity with Landlord with respect to the Facility exclusive of the Leased Premises.

ARTICLE 20.
ASSIGNMENT AND SUBLETTING

     20.1 Assignment and Subletting.

          (a) Landlord may sell, transfer, convey, assign or otherwise dispose of the Leased Premises or any part thereof, or all or any part of its right, title or interest as Landlord under this Lease, without the prior written consent of Tenant, provided that no such sale, transfer, conveyance, assignment or disposition shall be deemed to release or discharge the Leased Premises or any part thereof from the terms and conditions of this Lease, all of which shall continue in full force and effect with respect thereto, and further provided that such transferee or assignee agrees in writing to perform and be bound by all of the terms, covenants and conditions of this Lease with respect to the Leased Premises or part thereof, or right, title or interest as Landlord hereunder, so transferred or assigned by Landlord, and such transferee or assignee agrees in writing to release and hold harmless the then current Landlord, which is currently Noblegene Development, LLC from any liability or obligation hereunder. Without limiting the forgoing, the transferee or assignee shall expressly agree in writing that it will honor and be bound by the obligations set forth in the last sentence of Section 4.6 to return to the Tenant after expiration of this Lease the Security Deposit or any remaining balance thereof which it shall have received from the prior owner of the Leased Premises if the Tenant has fully and faithfully complied with all the terms of this Lease. Any assignee or transferee of the Landlord, upon written request, will provide Tenant with a subordination nondisturbance agreement or letter providing commercially subordination and nondisturbance provisions as may be reasonably acceptable to Landlord and Tenant.

          (b) Tenant may not assign all or any part of its rights, title or interest under this Lease, nor sublet all or any part of the Leased Premises, without the prior written consent of Landlord. If, after the proposed sublease, Tenant still maintains a presence within the CSLSC, and provided that Tenant remains liable to Landlord for all terms and conditions of this Lease including without limitation the payment of Rent to Landlord for the space covered by the proposed sublease, Landlord’s consent thereto shall not be unreasonably withheld.

          (c) Any attempted transfer, conveyance, assignment or subletting, whether by Landlord or by Tenant, which is not specifically permitted by this Lease or otherwise approved in accordance with this Section 20.1 shall be null and void and of no force and effect whatsoever; provided, however, that Landlord may collect Rent and other charges from the assignee, subtenant or other occupant and apply the amounts collected to the Rent and other charges herein reserved, but no such collection shall be deemed to be a waiver of Landlord’s right to enforce the requirements of this Section 20.1 or a release of Tenant from the performance of any of its covenants and agreements under this Lease.

     20.2 Subordination. Tenant shall insert in each sublease permitted under Section 20.1 provisions to the effect that (a) such sublease is subject and subordinate to all of the terms and provisions of this Lease and to the rights of Landlord hereunder.

     20.3 Current Subleases. Notwithstanding the restrictions on Tenant’s right to sublease included in this Article 20, Landlord hereby approves and/or ratifies Tenant’s current subleases with William Works and Williamson County.

ARTICLE 22.
QUIET ENJOYMENT

     Landlord covenants and agrees that, so long as no Event of Default has occurred and is continuing, Tenant shall peaceably and quietly have, hold, possess and enjoy the Leased Premises for the Term hereof, free of any hindrance, claim, disturbance or other action by Landlord or any other person or entity, subject to the tenant leases and except for any Taking of the Leased Premises by Condemnation, and that Landlord will, at the request of Tenant, defend the Tenant’s enjoyment and possession of the Leased Premises against all parties or permit the Tenant, in its own name and at its own expense, or to the extent lawful, in the Landlord’s name, to defend such enjoyment and possession.

ARTICLE 24.
TENANT’S RIGHT OF FIRST OFFER

     24.1 Right of First Offer. Provided that an Event of Default has not occurred and continuing, if during the term of this Lease and any extensions thereof Landlord desires to sell all or any part of the Building or any interest therein (“Offered Property”), Landlord shall give a notice (the “First Offer Notice") to Tenant. The First Offer Notice shall specify the price and terms of sale or transfer of interest including, without limitation, the description of the Offered Property, the type of deed or interest to be delivered, the exceptions to which the Offered Property will be subject, whether or not title insurance will be provided, and the allocation of responsibility for sales and documentary taxes and other closing costs. The First Offer Notice shall constitute an offer by Landlord to sell or transfer its interest in the Offered Property to Tenant on the price and terms and conditions set forth in such notice.

     24.2 Tenant Acceptance/Rejection. Tenant shall, within fifteen (15) days after the giving of the First Offer Notice (“Offer Period”), give Landlord written notice of either: (1) Tenant’s desire to accept such offer (the “Acceptance Notice"), or (2) a counter offer setting forth the price and terms of sale or transfer that would be acceptable to Tenant (“Counter Offer”). In the event that Tenant shall not give Landlord the Acceptance Notice or Counter Offer within the Offer Period, and subject to Tenant’s right to tender a Firm Offer in accordance with Section 24.3, for a period of Twelve (12) months following the Offer Period (“12-Month Sale Period”) Landlord may sell the Offered Property to any party at any price that Landlord deems appropriate, and nothing herein shall require Landlord to sell the Offered Property at the price included in the First Offer Notice. In the event that Tenant gives Landlord one or more Counter Offers within the Offer Period that are rejected by Landlord, for a period of six (6) months following the Offer Period (“6-Month Sale Period”), if Landlord elects to sell or transfer the Offered Property at a price that is less than Tenant’s highest Counter Offer price or on terms more favorable to the acquirer than the terms included in Tenant’s highest Counter Offer, Landlord shall provide Tenant with written notice of its intent to do so (“Revised Offer Notice”), and Tenant may elect to acquire the Offered Property on the proposed new terms in the Revised Offer Notice by providing Landlord with a written Acceptance Notice within five (5) business days of Tenant’s receipt of the Revised Offer Notice. Notwithstanding the foregoing provisions, if prior to the expiration of the applicable 6-Month Sale Period or 12-Month Sale Period Landlord has not entered into a definitive agreement for the sale or transfer of the Offered Property, any subsequent transaction shall be subject to Tenant’s Right of First Offer set for the Section 24.1.

     24.3 During any pending 12-Month Sale Period Tenant may tender a firm offer to purchase the previously Offered Property (“Firm Offer”). If Landlord rejects Tenant’s Firm Offer, Landlord must provide Tenant written notice of its rejection thereof within five (5) business days of Landlord’s receipt of the Firm Offer. Upon the date of such written notice of rejection the then pending 12-Month Sale Period shall terminate and a new 6-Month Sale Period shall begin. If Landlord subsequently elects during the new 6-Month Sale Period to sell

or transfer the Offered Property at a price that is less than Tenant’s Firm Offer price or on terms more favorable to the acquirer than the terms included in Tenant’s Firm Offer, Landlord shall provide Tenant with a written Revised Offer Notice, and Tenant may elect to acquire the Offered Property on the proposed new terms in the Revised Offer Notice by providing Landlord with a written Acceptance Notice within five (5) business days of Tenant’s receipt of the Revised Offer Notice.

     24.4 Purchase Agreement. In the event that Tenant gives Landlord an Acceptance Notice or Landlord accepts a Counter Offer or Firm Offer, then within thirty (30) days thereof, the parties shall enter into binding letter of intent regarding the transfer of the Offered Property on the terms stated in the First Offer Notice, Revised Offer Notice, Counter Offer, or Firm Offer and subject to standard contingencies such as financing and an inspection as may be required. Within ninety (90) days of the Acceptance Notice the Landlord and Tenant shall enter into a definitive agreement for the transfer of the Offered Property on the terms stated in the First Offer Notice, Revised Offer Notice, Counter Offer or Firm Offer, and upon such other terms and conditions to which the parties agree.

     24.5 Recordation of Right. Tenant shall have the right to record a Memorandum of Tenant’s Right of First Offer in the official records of Williamson County, Franklin, TN provided that Landlord reviews and approves the Memorandum of Tenant’s Right of First Offer prior to recordation.

     26.12 No Third Parties. This Lease is solely for the benefit of the Landlord and the Tenant and their respective successors and permitted assigns. Nothing contained in this Lease, express or implied, is intended to or shall confer upon or create in any person or entity, other than the Landlord and the Tenant, their respective successors and permitted assigns, any rights or remedies under or by reason of this Lease, and no other person or entity shall be deemed to be a beneficiary of the terms, conditions, covenants and agreements contained and set forth in this Lease.

This waiver shall be nontransferable and shall apply only to Noblegene.

     Please countersign this letter, if you agree that this accurately reflects the understanding between the parties regarding this matter.

Sincerely,
