5. ADDITIONAL RENT (“OPERATING EXPENSES”); TENANT IMPROVEMENT RENT (“TI RENT”).

5.1 OPERATING EXPENSES. For the purposes of this Lease, “Operating Expenses” for any calendar year shall mean all (or where specified by Lessor as hereinafter permitted or required, an amortized portion of all as determined in accordance with generally accepted accounting principles consistently applied) expenses, costs and accruals of every kind and nature, computed on an accrual basis, incurred or accrued in connection with, or relating to, the ownership, maintenance, or operation of the Business Park, during such calendar year, including, but not limited to, the items set forth below in paragraphs A through E of this Section 5. Notwithstanding the foregoing, the items set forth on Addendum #9 to this Lease shall not be included in the calculation of Operating Expenses.

Notwithstanding anything to the contrary contained herein, LESSEE shall only be responsible for the payment of LESSEE’s Share of such Operating Expenses. “LESSEE’s Share” means the proportionate amount of rentable area within the Business Park which is leased to LESSEE based on a fraction, the numerator of which is the total rentable area located within the Premises, and the denominator of which is the total rentable area within all buildings in the Business Park. For purposes hereof, LESSEE’s Share shall initially be twenty and 9/10ths percent (20.9%).

A. Insurance. The total premium(s), together with any increases thereof, for LESSOR’s policy or policies of insurance insuring the Business Park against damage or destruction by fire or other casualties insured under extended coverage endorsement (or such other coverage as LESSOR shall determine to be necessary, including, but not limited to, umbrella liability coverage). LESSOR will periodically notify LESSEE of LESSEE’s Share of said premium(s), and LESSEE’s Share of any increases. If actual amounts are unavailable, LESSOR may estimate the amounts of such premiums and increases, subject to reconciliation as provided herein.

B. Taxes. All taxes, assessments and governmental charges of any kind or nature relating to the Business Park, whether or not directly paid by Lessor, whether federal, state, municipal, local or other, and whether they be by taxing districts or authorities presently taxing the Business Park or by others subsequently created or otherwise, and any other taxes, assessments and governmental changes attributable to the Business Park or its operation, and specifically including fifty percent (50%) of any State of Texas franchise or margin tax incurred by LESSOR and calculated on rental income generated from the Business Park, but specifically excluding taxes and assessments attributable to the personal property of any tenants, federal taxes on income, death taxes, and any taxes imposed or measured on or by the income of Lessor from the operation of the Business Park (other than State of Texas franchise or margin tax, 50% of which shall be included in Operating Expenses as provided above); provided, however, that if at any

3

time during the term of this Lease, the present method of taxation or assessment shall be changed such that the whole or any part of the taxes, assessments, or governmental charges now levied, assessed or imposed on real estate, improvements or personal property shall be discontinued or reduced, in whole or in part, and as a substitute therefore, or in lieu of or in addition thereto, taxes, assessments, or governmental charges shall be levied, assessed or imposed, wholly or partially, on (or shall be calculated with reference to) the rents received from the Business Park, or the rents reserved herein, or the income of Lessor in respect of the Business Park, or any such rents, then such substitute, additional or increased taxes, assessments, or governmental charges, to the extent so levied, assessed or imposed, shall be deemed to be included within the Operating Expenses. Consultation, legal fees and costs in connection with any challenge of tax assessments as reasonably allocated by Lessor shall also be included in Operating Expenses. Lessee will be responsible for and shall timely pay all ad valorem taxes on its personal property and on the value of the leasehold improvements installed in the Premises by or at LESSEE’s request to the extent that the same exceed building standard (and if the taxing authorities do not separately assess Lessee’s leasehold improvements, Lessor may make a reasonable allocation of the ad valorem taxes allocated to the Business Park to give effect to this sentence. In the case of special taxes and assessments which may be payable in installments, only the amount of each installment accruing during a year shall be included in the Operation Expenses for such year.

C. Common Area and Other Maintenance Type Expenses. In the event LESSOR provides maintenance, security, janitorial, cleaning and/or utility services to the Business Park, or installs equipment devices or material which LESSOR reasonably believes will reduce the Operating Expenses of the Business Park (provided that such belief is based on the documented reasonable opinion of an engineer or other appropriate third-party), or that are required by governmental authority to comply with any laws enacted after the Commencement Date for the Common Areas in the Business Park of any portion of the Demised Premises, then the cost to LESSOR of providing such maintenance, security, janitorial, cleaning, utility services, equipment and/or devices, together with a reasonable allowance for overhead (including but not limited to, management fees not to exceed then current market rates for similar properties to the Business Park). Except as otherwise provided herein, the nature and degree of services rendered by LESSOR in accordance with this subsection, if any, shall be in the sole discretion of LESSOR. LESSOR may estimate such items in advance, subject to reconciliation as provided herein.

D. Utilities. Any utilities supplied to the Common Areas of the Business Park.

As soon as reasonably possible after the end of each calendar year, but in any event not later than ninety (90) days after the end of such calendar year, LESSOR shall deliver to LESSEE a written notice indicating the actual amount of Operating Expenses incurred during such calendar year. In connection with Additional Rent for insurance premiums, taxes and common area maintenance under subsections A., B. and C. above, if LESSOR has estimated the amounts, LESSEE’s Share will be adjusted based upon the

4

actual amounts of premiums, taxes and expenses identified in such notice. LESSEE will be allowed a credit against payments next coming due (or, if the Lease Term has expired, LESSOR will pay to LESSEE at the time LESSOR provides the notice described above in this paragraph) for any estimated payments made in excess of LESSEE’s Share of actual Operating Expenses. LESSEE will pay within thirty (30) days after receipt of such written notice from LESSOR any amounts due in excess of estimated payments previously made.

LESSOR shall maintain full, complete and accurate books and records relating to Operating Expenses. LESSEE shall have the right, at its expense, to audit LESSOR’s books and records to verify the amount of charges to LESSEE relating to insurance, real property taxes, common area and other maintenance type expenses, utilities and other amounts and any other costs which LESSEE is required to pay a proportionate share. If such audit reveals that the amount charged to LESSEE is incorrect, LESSOR and LESSEE shall make an appropriate adjustment in cash within thirty (30) days after completion of the audit. If such audit reveals that LESSEE was overcharged for such expense by more than five percent (5%) over the actual amount due and owing by LESSEE, LESSOR will also reimburse LESSEE for the cost of such audit.

E. Other Amounts. LESSEE’s Share of Operating Expenses, and all other taxes, charges, costs and expenses which LESSEE is required to pay hereunder, together with all interest and penalties that may accrue thereon pursuant to this Lease in the event of LESSEE’s failure to pay such amounts, and all damages, costs and expenses to which LESSOR shall be entitled hereunder by reason of any default of LESSEE or failure on LESSEE’s part to comply with the terms of this Lease beyond applicable cure periods, and the interest upon unpaid obligations provided hereunder, shall all be deemed to be “Additional Rent” and, in the event of nonpayment by LESSEE beyond any applicable cure periods, LESSOR shall have all the rights and remedies with respect thereto as LESSOR has for the payment of the Basic Rent.

5.2 TI RENT. In consideration for the Basic Rent that LESSOR agrees to pay under the Lease for the Lease Term, LESSOR has agreed to provide LESSEE with an improvement allowance of $500,000.00 (“Allowance”) for improvements to the Premises to be made by LESSOR as set forth in Exhibit C attached hereto (the “Tenant Improvements”). In addition, LESSOR has agreed to make available to LESSEE an additional allowance of up to an additional $300,000 (subject to LESSEE having first contributed $400,000 of LESSEE’s funds toward the cost of the Tenant Improvements) for the Tenant Improvements (the “Additional Allowance”); provided, however, as consideration for LESSOR providing the Additional Allowance to LESSEE, LESSEE agrees to pay LESSOR, in addition to the Basic Rent, a monthly amount equal to the amount required to fully amortize the Additional Allowance, plus interest on Additional Allowance at the rate of seven percent (7%) per annum from the Commencement Date through the end of the initial Lease Term, such amortization to begin on first day of the sixth full calendar month after the Commencement Date through the end of the initial Lease Term (the “TI Rent”). Assuming LESSEE utilizes the entire $300,000 available as the Additional Allowance, and further assuming the Commencement Date is on the first day of a calendar month, then the monthly TI Rent commencing on the first day of the sixth full month of the Lease Term would be $3,566 per month. Lessor shall notify Lessee of Lessor’s calculation of monthly TI Rent (including a copy of the amortization schedule used to calculate such amount) prior to the Commencement Date.

5

The Basic Rent, Additional Rent, TI Rent and all other amounts of whatever kind or character payable to LESSOR by LESSEE hereunder (all hereinafter included in the term “rent”) shall, except as otherwise provided herein, be paid without notice of demand and without abatement, counterclaim, deduction, setoff or defense, and any amounts due and owing hereunder by one party to the other and not paid when due shall bear interest at the rate of twelve percent (12%) per annum (or the highest legal rate provided by then controlling law if less than twelve percent (12%) from the due date until paid).

Subject to the initial period of free Rent set forth on Addendum #1, the initial amount of rent is computed as follows (based on a Premises containing square feet):

Annual Rate |  | Annual Amount |  | Monthly Amount
Basic Rent( sq. ft.) |  |  |  |
Additional Rent (estimated for 2009): |  |  |  |
Common Area Maintenance ( sq. ft.) |  |  |  |
Real Property Taxes sq. ft.) |  |  |  |
Insurance sq. ft.) |  |  |  |
Total Rent (does not include TI Rent, if applicable) |  |  |  |

6. SECURITY DEPOSIT. Intentionally Deleted.

If such persons are not present, LESSOR, LESSOR’s representatives or servicemen will provide LESSEE with twenty four (24) hours notice before such entry (unless in the event of an emergency, no prior notice will be provided by LESSOR to LESSEE, but LESSOR shall notify LESSEE as soon thereafter as is reasonably practicable), in order to enter by duplicate key or master key during LESSEE’s normal business hours (or such other hours as LESSOR and LESSEE may mutually schedule) for the following purposes: repairs, extermination, preventive maintenance, security, recovery of tools on loan, safety and fire inspections, showing the Premises to building inspectors, fire marshals, mortgage lenders, prospective purchasers or insurance agents. Notwithstanding anything to the contrary contained herein, LESSOR shall use reasonable, good faith efforts to schedule and perform any such entries, and any work to the Building B Parking Areas, drives or other Common Areas directly adjacent to the Building in such a manner as to minimize the inconvenience to LESSEE’s business.

If LESSOR and LESSEE shall not have renewed or extended this Lease prior to the final ninety (90) day period of the Lease Term, LESSOR and its authorized agents shall have the right to erect on or about the Demised Premises a customary sign advertising the property for lease or for sale. During said ninety (90) day period LESSOR and its authorized agents shall have the right to enter the Demised Premises upon not less than one (1) hour notice, and during LESSEE’s normal business hours, for

12

the showing of the Demised Premises to prospective Lessees or purchasers. Notwithstanding the foregoing, LESSEE shall have the right, in connection with any entry of the Premises by LESSOR or any other party under this Section 12.B., to take reasonable precautions, and to require (and LESSOR and such other parties shall observe) reasonable restrictions on access to any areas of the Premises in which LESSEE stores, operates, or uses any proprietary information, applications or processes, or from which such information, applications or processes are visible.

13. PARKING. LESSEE shall, at no additional cost throughout the term of the Lease, including any extensions or renewals thereof, have the exclusive right to use all of the Building B Parking Spaces as denoted on Exhibit A-1 within which LESSEE and its agents and employees and invitees may park vehicles driven by them, and LESSEE covenants and agrees that all such vehicles will be parked only within the Building B Parking Spaces LESSOR agrees, at LESSOR’s sole cost and expense, to seal coat and restripe the Building B Parking Spaces prior to the Commencement Date.

14. MAINTENANCE BY LESSOR. LESSOR shall only maintain and repair the roof, foundation, and the structural soundness of the exterior walls (excluding all windows, window glass, plate glass and all doors) of the Demised Premises in good working order and condition, except for reasonable wear and tear. LESSOR shall also maintain the Common Areas (including without limitation all drives, sidewalks, landscaping and the Business Park Monument Sign) of the Business Park in a good and workmanlike manner consistent with the way LESSOR has been maintaining such Common Areas as of the date of this Lease, but in any event in a manner at least as good as comparable developments in the Austin, Texas market, and LESSEE shall reimburse LESSOR for LESSEE’s Share of expenses incurred by LESSOR in order to maintain the Common Areas, as stated in Paragraph 5 “Additional Rent”. In the event that, during the initial twelve (12) month period following the Commencement Date, any of the equipment serving the Premises is or becomes in need of replacement, and LESSEE’s engineer or a third-party service professional reasonably determines that such equipment has reached the end of its useful life and needs to be replaced, LESSOR shall, at LESSOR’s sole cost and expense, replace such equipment with new equipment of a similar or better character and quality, and shall assign any warranties for such new equipment to LESSEE; provided, however, if LESSEE elects to move and relocate any such equipment during the initial twelve (12) month period of the Lease Term, the cost to move, relocate, repair or replace (but with respect to a replacement, only in the event that the need to replace such equipment results from moving or relocating such equipment) such moved or relocated equipment shall be paid by LESSEE. After the expiration of such initial twelve (12) month period of the Lease Term and continuing until the first day of month that is nine (9) months prior to the expiration of the Lease Term, if LESSEE’s engineer, LESSOR’s engineer, or a third-party service professional reasonably determines that such equipment has reached the end of its useful life and needs to be replaced, LESSEE shall, at LESSEE’s sole cost and expense, replace such equipment with new equipment of a similar or better character and quality. LESSOR shall be responsible, at LESSOR’s sole cost and expense (subject to reimbursement in Operating Expenses, if otherwise permitted hereunder), for any capital replacements required during the final nine (9) months of the Lease Term. If the Premises are in need of any of the limited repairs or

13

replacements for which LESSOR is liable to perform under the terms of this Lease, LESSEE shall give LESSOR prompt written notice specifically setting forth the nature of such needed repairs or replacements. LESSOR shall not have any liability or obligation to make any repairs or replacements until LESSEE has provided the aforesaid written notice to LESSOR. LESSOR’s liability hereunder is expressly limited to the cost of the repairs and replacements, and LESSOR shall have no liability for, and LESSEE agrees to release LESSOR from, any loss, damage, claim or other costs in excess of the cost of the repairs and replacements arising from such repairs, replacements or the cause thereof. LESSOR agrees to use commercially reasonable efforts to complete any such repairs or replacements within thirty (30) days after such written notice; provided, however, if such repairs are not reasonably capable of repair within such thirty (30) day period, LESSOR agrees to timely commence such repairs and replacements and proceed to diligently complete such repairs in a reasonable period of time, using commercially reasonable efforts, acting in good faith. If LESSOR fails to timely complete such repairs and replacements as provided in the preceding sentence (or, in the event of any condition which results, or is reasonably likely to result, in any property damage or personal injury, within ten (10) days after such notice), LESSEE shall have the right to perform such repairs or maintenance, and any expenses incurred by LESSEE shall be reimbursed to LESSEE within thirty (30) days after written notice plus, in the event such expenses are not repaid within such thirty (30) day period, interest thereon at the rate of twelve percent (12%) per annum from the date due until paid. LESSOR reserves the right to place over, under or behind the Demised Premises pipes, wires, lines and other facilities serving other areas of the Business Park, and will not unreasonably interfere with the use of the Demised Premises, provided that LESSOR shall be responsible for maintaining same in good working order and condition.

LESSEE will permit LESSOR and LESSOR’s agents, employees or representatives to enter into and upon any and all parts of the Demised Premises upon reasonable advance notice and during LESSEE’s normal business hours (unless LESSOR and LESSEE schedule a different mutually agreeable time) to inspect same or make such repairs or alterations as LESSOR reasonably deems necessary, and LESSEE shall not be entitled to any abatement or reduction of rent by reason thereof. LESSOR shall be entitled to make such repairs and alterations of Common Areas and grounds in the Business Park as LESSOR reasonably deems necessary, and LESSEE shall not be entitled to any damages or abatement or reduction of rent by reason thereof even though such repairs or alterations may affect temporarily LESSEE’s use of the Demised Premises, provided that LESSOR will not unreasonably interfere with the use of the Demised Premise, and shall use good faith efforts to minimize any inconvenience to LESSEE’s business caused by such activities (including, without limitation, scheduling such activities outside LESSEE’s normal business hours to the extent possible).

15. MAINTENANCE BY LESSEE. LESSEE shall at its expense and risk maintain all other parts of the Premises and the Building B Parking Spaces in good repair and condition except for normal wear and tear, casualty and condemnation, including but not limited to repairs (including all necessary) to the interior plumbing, windows, window glass, plate glass, doors, fire protection sprinkler system, and the interior of the Demised Premises in general. LESSEE shall provide preventative maintenance to the heating and air conditioning equipment and system. LESSEE will provide and maintain vermin-proof receptacles for LESSEE’s own use in the event refuse is temporarily stored

14

outside of the Demised Premises, and LESSEE will be responsible for the removal of said refuse and will promptly and strictly comply with all health, sanitary or other laws, regulations and ordinances pertaining to the depositing and removal of such refuse from or about the Demised Premises. Such receptacle shall be solely in such areas, if any, designated by LESSOR in LESSOR’s reasonable discretion, such areas to be reasonably near the Premises. LESSEE will not use the Common Areas or other area outside of the Premises to store any pallets, cartons, equipment or other materials except solely for the limited equipment approved for outside storage as specifically set forth on Exhibit D. LESSEE further agrees to be responsible for sweeping and cleaning the Demised Premises. LESSEE will maintain, repair and replace when necessary, the air conditioning, plumbing, gas and electrical appurtenances and fixtures in the Demised Premises, and LESSEE will enter into and keep in force throughout the Lease Term a HVAC maintenance contract with a HVAC maintenance contractor reasonably acceptable to LESSOR. LESSOR will not be liable to LESSEE or any other persons whomsoever for injury or damage to persons or property received on or incidental to the use of said Demised Premises during the Term of this Lease, and LESSEE will indemnify, defend and save harmless LESSOR from and against any loss, claim, expense or liability in connection therewith including LESSEE’s failure to repair unless caused by the gross negligence or willful misconduct of LESSOR or LESSOR’s agents, employees, contractors or representatives. LESSEE shall not be required to make any capital replacements during the final nine (9) months of the Lease Term.

LESSEE shall throughout the Lease Term take good care of the Demised Premises and keep them free from waste, and shall deliver up the Demised Premises broom-clean at the termination of this Lease in at least the condition in which they were in on the Commencement Date, (reasonable wear and tear, casualty and condemnation excepted).

In the event LESSEE should fail to maintain the Demised Premises as required hereunder and such failure continues for more than thirty (30) days after written notice from LESSOR, LESSOR shall have the right (but not the obligation) to cause repairs or corrections to be made and any out of pocket third party costs thereof shall be payable by LESSEE to LESSOR as Additional Rent within thirty (30) days after LESSOR presents LESSEE with a written invoice therefor.

16. TAXES. LESSOR shall pay all real estate ad valorem taxes levied against the Business Park during the Term of this Lease. LESSEE shall pay all taxes on personal property within the Premises, all sales taxes or occupations taxes on LESSEE’s business and any and all other taxes attributable to LESSEE or LESSEE’s business.

17. INSURANCE AND INDEMNIFICATION; WAIVER OF SUBROGATION. LESSOR shall pay for property insurance coverage (formerly “fire and extended coverage - all-risk”) on the Business Park (including the Premises and the leasehold improvements located therein) in an amount equal to the full replacement cost thereof. LESSEE agrees to obtain and maintain during the Lease Term the insurance coverage set forth on Exhibit F attached hereto. LESSEE shall provide LESSOR with a certificate of

15

such insurance prior to the Commencement Date of this Lease. LESSOR shall provide for commercial general liability insurance for its business operations in the Business Park as follows: bodily injury and property damage of not less than $2.0 Million combined single limits. LESSOR’s insurance policies shall comply with the General Insurance Requirements set forth in Sections 2(a)(i), 2(a)(iii) and 2(b)(i) of Exhibit F attached hereto.

LESSOR shall not be liable to LESSEE or LESSEE’s agent, employees, guests or invitees, or to any person claiming by or through LESSEE for any injury to any person or damaged property or for the loss or damage to LESSEE’s business, occasioned by or through the acts of omissions of LESSOR or any person, or by and other cause whatsoever, except LESSOR’s negligence or willful misconduct. Subject to the paragraph immediately following, LESSEE shall indemnify LESSOR and save LESSOR harmless from all suits, actions, damages, liability and expense in connection with personal injuries or property damage arising in or on the Premises or occasioned by any negligence or willful misconduct of LESSEE, LESSEE’s agents, contractors, employees, servants, invitees or licensees which may occur during the term of this Lease, except if it is determined to be caused by LESSOR, LESSOR’s agents, contractors, employees, servants, invitees or licensees. Subject to the paragraph immediately following, LESSOR shall indemnify LESSEE and save LESSEE harmless from all suits, actions, damages, liability and expense in connection with personal injuries or property damage arising in or on the Business Park or occasioned by the negligence or willful misconduct of LESSOR, LESSOR’s agents, contractors, employees, servants, invitees or licensees which may occur during the term of this Lease, except if it is determined to be caused by LESSEE, LESSEE’s agents, contractors, employees, servants, invitees or licensees.

Notwithstanding anything in this Lease, or in any insurance policy to be obtained under this Lease, to the contrary, LESSOR and LESSEE each hereby WAIVES any and all rights of recovery, claim, action or cause of action against the other, its partners and affiliates, and its and their agents, servants, shareholders, officers, directors, managers, members, principals or employees and their respective insurance carriers, for any loss or damage that may occur to the Premises, the Business Park, or any personal property or fixtures of such party therein or thereon, by reason of fire, the elements, or any other cause, in each case only to the extent same is insured against or required to be insured against under the terms of the insurance policies referred to in this Paragraph 17, regardless of cause or origin, including, without limitation SOLE, JOINT OR CONCURRENT NEGLIGENCE, SOLE, JOINT OR CONCURRENT GROSS NEGLIGENCE, WILLFUL MISCONDUCT, STRICT LIABILITY, OR OTHER FAULT OF EITHER OR BOTH OF THE PARTIES HERETO AND THEIR RESPECTIVE AGENTS, SERVANTS, EMPLOYEES, OFFICERS, DIRECTORS, SHAREHOLDERS, PARTNERS, ARCHITECTS, CONTRACTORS, SUBCONTRACTORS, ATTORNEYS, CUSTOMERS AND INVITEES. Each party waives and covenants that no insurer shall hold (and hereby waives on behalf of such insurer) any right of subrogation against such other party as a result of such claims. If the respective insurer of LESSOR and LESSEE does not permit such a waiver without an appropriate endorsement to such party’s insurance policy, then LESSOR and LESSEE

16

each shall notify its insurer of the waiver set forth herein and shall secure from such insurer an appropriate endorsement to its respective insurance policy with respect to such waiver. The foregoing waiver of recovery and subrogation provisions shall also apply to any other insurance obtained and maintained by either LESSOR or LESSEE, except such waivers shall be limited to liabilities and indemnities assumed under this Lease by LESSOR and LESSEE, respectively.

18. DESTRUCTION OR CONDEMNATION. In the event of total damage or destruction of the Premises, both LESSOR and LESSEE shall have the option to terminate this Lease in its entirety. In the event of partial damage or destruction of the Premises by fire or other cause, LESSOR shall deliver to LESSEE, within thirty (30) days of such damage or destruction, a written opinion from LESSOR’s architect stating the estimated time needed to repair or rebuild the Premises to its condition immediately prior to the occurrence of such damage or destruction. In the event that such notice states that such repair or reconstruction of the Premises to its previous condition shall take longer than one hundred eighty (180) day after the occurrence of such damage or destruction, both LESSEE and LESSOR shall have the option to terminate the Lease in its entirety by notifying the other in writing within fifteen (15) days after such notice is delivered. In the event that this Lease is not so terminated, LESSOR shall be obligated to reconstruct and repair the Premises to a condition substantially the same as that existing prior to the casualty, and shall promptly commence and proceed with due diligence in such repair or reconstruction and use commercially reasonable efforts (including, without limitation, performing such work on weekends if reasonably necessary to timely complete the work) to complete such work as soon as is reasonably practicable, provided that if such repair or reconstruction is not completed within one hundred eighty (180) days after the date of such casualty, LESSEE shall have the option to terminate this Lease; provided further, however, if the repair or reconstruction work is at least ninety percent (90%) complete on the 180th date after such casualty, LESSEE shall not have the right to terminate this Lease as long as LESSOR substantially completes the repair or reconstruction within thirty (30) days thereafter. In the event that this Lease is not terminated as provided above, Rent shall abate proportionately from the date of such damage or destruction until the Premises is repaired or reconstructed to a condition substantially the same as that existing prior to the casualty. In the event that this Lease is terminated under this Paragraph 18, such termination shall be effective as of the date of the casualty. LESSOR shall not be responsible for damage or destruction to LESSEE’s trade fixtures, furniture and/or equipment; and LESSEE shall have the sole responsibility of carrying insurance or the risk of loss thereof.

LESSOR shall promptly notify LESSEE in writing of any condemnation or threatened condemnation affecting the Business Park. If the entire Premises are taken in condemnation, this Lease shall terminate one (1) day prior to such taking. If part of the Premises (but less than all of the Premises) or any parking areas associated therewith or access thereto is taken in condemnation (a ‘‘Partial Taking”), and such Partial Taking will, in LESSEE’s reasonable judgment, materially and adversely affect LESSEE’s ability to use the Premises for the purposes of carrying on LESSEE’s business to the same extent as carried on prior to such Partial Taking, then LESSEE may terminate this

17

Lease by written notice to LESSOR given within 30 days after LESSEE receives actual notice of the Partial Taking, such termination to be effective one (1) day prior to such Partial Taking In the event of a Partial Taking, and if this Lease is not terminated as provided above, LESSOR shall repair and reconstruct the Premises to the extent necessary to allow LESSEE to continue operating LESSEE’s business from the portion of the Premises remaining, and rent shall be permanently abated to the extent that such partial taking reduces the usable space of the Premises or LESSEE’s parking rights or access to the Premises. LESSEE shall not participate in any of the condemnation award, provided that LESSEE shall have the right to assert a claim for and recover from the condemning authority, but not from LESSOR, such compensation as may be awarded on account of LESSEE’s moving and relocation expenses, loss to any of LESSEE’s property, and depreciation to and loss of any leasehold improvements constructed by or on behalf of LESSEE. Except as provided above, all awards or compensation received during the Term of this Lease by reason of condemnation by any government or governmental agency (or private sale in lieu of such condemnation) of all or any portion of the Premises, the Business Park or land upon which it is situated shall belong entirely to LESSOR; and LESSEE hereby assigns its interest, if any, in such awards to LESSOR.

19. DEFAULT BY LESSOR. LESSOR shall not be in default under this Lease, and LESSEE shall not be entitled to exercise any right, remedy or recourse against LESSOR or otherwise as a consequence of any alleged default by LESSOR under this Lease, unless and until LESSOR fails to perform any of its obligations hereunder and said failure continues for a period of 30 days after LESSEE gives LESSOR written notice thereof specifying, with reasonable particularity, the nature of LESSOR’s failure; provided, however, that if the failure can be cured but not within the 30 day time period, LESSOR shall not be in default hereunder if LESSOR commences to cure the failure within such 30 days and thereafter in good faith pursues the curing of same diligently to completion. If LESSOR defaults under this Lease, and, as a consequence of the default, LESSEE recovers a money judgment against LESSOR, the judgment shall be satisfied only out of, and LESSEE hereby agrees to look solely to, the interest of LESSOR in the Business Park as the same may then be encumbered, and any proceeds thereof, and LESSOR shall not otherwise be liable for any deficiency. In no event shall LESSEE have the right to levy execution against any property of LESSOR other than its interest in the Business Park or any proceeds thereof. The foregoing shall not limit any right that LESSEE might have to obtain specific performance of LESSOR’s obligations hereunder.

20. DEFAULT BY LESSEE. The occurrence of any of the following beyond the applicable cure periods shall constitute a default (an “Event of Default”) by LESSEE:

A. Failure to pay rent or any other amounts to be paid by LESSEE, when due, if failure continues for ten (10) days after due date and an additional five (5) days after written notice by LESSOR, or

B. LESSEE shall admit in writing its inability to pay its debts and obligations as they come due, or shall make an assignment for the benefit of creditors.

18

C. LESSEE shall file a petition under any section or chapter of the Federal Bankruptcy Code, as amended, or under any similar law or statute of the United States or any State thereof, or LESSEE shall be adjudged bankrupt or insolvent in proceedings filed against LESSEE thereunder.

D. A receiver or trustee shall be appointed for all or substantially all of the assets of the LESSEE and shall not be discharged within sixty (60) days after such appointment.

E. LESSEE’s failure to perform any other provisions of this Lease if the failure to perform is not cured within thirty (30) days after written notice by LESSOR to LESSEE has been given. Provided, however, if the LESSEE’s breach cannot reasonably be cured in the thirty (30) days provided above, LESSEE shall not be in default of this Lease if LESSEE commences to cure the default within the 30-day period and diligently proceeds in good faith to cure the breach.

21. LESSOR’s REMEDIES. Upon the occurrence of any of such Events of Default after the expiration of any applicable notice and cure period, LESSOR shall have the option to pursue any one or more of the following remedies without any notice or demand whatsoever:

A. Terminate this Lease by giving LESSEE written notice thereof, whereupon LESSOR may alter the locks or other security devises at the Premises and may peaceably remove all persons and property therefrom as allowed by law, for this purpose without being guilty in any manner of trespass or otherwise; and any such termination or re-entry on the part of LESSOR shall be without prejudice to and remedy available to LESSOR for arrears of rent and charges owed LESSOR by LESSEE, breach of contract, damages or otherwise. Termination pursuant hereto shall not relieve LESSEE’s obligation for damages suffered by LESSOR as a result of LESSEE’s breach.

B. Without terminating this Agreement, enter upon the Premises without disturbing the peace, by changing the locks and other security devices at the Premises or such other peaceable method as LESSOR may desire, and without being guilty in any manner of trespass or otherwise, and do or perform whatever LESSEE is obligated hereunder to do or perform under the terms of this Lease; and the LESSEE shall reimburse the LESSOR on demand for any expenses or other sums which LESSOR may reasonably incur or expend, thus effecting compliance with the terms and provisions of this Lease; provided, however, nothing in this subsection shall be deemed an obligation or undertaking by LESSOR to remedy any such defaults of LESSEE. In the event LESSOR elects to re-enter without terminating this Agreement pursuant to this subsection, LESSOR shall have the right, but not the obligation, to relet the LESSEE’s right to the Premises upon such terms, conditions and covenants as are deemed proper by LESSOR for the account of LESSEE and in such event, LESSEE shall pay to LESSOR all reasonable costs of renovating and altering the Premises for a new Lessee or Lessees, in addition to all brokerage fees, if any, incurred in connection therewith, together with the difference between the rent recovered by LESSOR from such reletting and that owed by LESSEE.

19

C. Pursuit of any of the foregoing remedies by LESSOR shall not preclude pursuit of any other remedies herein provided LESSOR or any other remedies provided by law, nor shall pursuit of any of the other remedies herein provided constitute a forfeiture or waiver of any fee or charge due LESSOR hereunder or of any damages accruing to LESSOR by reason of the violation of any of the terms, provisions and covenants herein contained. Forbearance by either party hereto to enforce one or more of the remedies herein provided upon a default of the other shall not be deemed or construed to constitute a waiver of such default.

No re-entry or taking possession of the Premises by LESSOR shall be considered as an election on LESSOR’s part to terminate this Lease unless written notice of such termination is given to LESSEE. Notwithstanding any reletting without termination subsequent to LESSEE’s default, LESSOR may at any time thereafter elect to terminate this Lease for the previous breach. If LESSEE is in default beyond any applicable cure periods, LESSOR shall not be obligated to continue any utilities, which are furnished or paid for by LESSOR.

If LESSEE is more than ten (10) days delinquent in rent payments, LESSEE’s failure to pay rent in full within five (5) days after written demand therefore shall entitle LESSOR to change or modify door locks on the Premises, provided LESSOR leaves a written notice on the door informing LESSEE where a new key can be picked up by LESSEE, during reasonable business hours, if and only if, the delinquency in rent payments along with all other damages (late fees, locksmith, etc.) are paid in full. Such modification of the locks shall not in any way be considered constructive eviction. LESSOR may report unpaid rentals or unpaid damages to any credit bureau for permanent recordation in LESSEE’s credit record, only in the case of default by LESSEE beyond applicable cure periods, as defined in Paragraph 20. “Default by LESSEE”.

22. SURRENDER AND HOLDOVER. In the event LESSEE remains in possession of the Premises after the expiration of this Lease without the execution of a new lease, it shall be deemed to be occupying the Premises as a tenant at sufferance, subject however to all of the terms, conditions, provisions and obligations of this Lease, except the monthly rent during such holdover shall be equal to the rent payable during the last month of the Lease Term immediately prior to the holdover (including Basic Rent and Additional Rent) plus fifty percent (50%) of such amount; provided, however, if LESSEE holds over for more than three months after the expiration of the Lease Term, the monthly rent payable during any remaining holdover period shall be equal to the greater of (i) one hundred fifty percent (150%) of the rent payable during the last month of the Lease Term immediately prior to the holdover (excluding, however, TI Rent), or (ii) one hundred thirty percent (130%) of the then current fair market rental rate for the Premises. The foregoing shall not constitute LESSOR’s consent for LESSEE to holdover for any period of time. If LESSEE remains in possession of the Premises after the expiration of this Lease without LESSOR’s consent, LESSEE shall also pay to LESSOR all damages sustained by LESSOR resulting from retention of possession by LESSEE, including without limitation, the loss of any proposed subsequent third-party tenant for all or any

20

portion of the Premises, provided that LESSOR shall not be liable for any such damages resulting from the loss of any proposed subsequent third-party tenant unless LESSEE holds over for thirty (30) days or longer after LESSOR has notified LESSEE in writing that the LESSOR has entered into a new lease for the Premises with such subsequent third-party tenant

Not later than the last day of the Term, LESSEE shall surrender the Premises in as good condition as they were at the beginning of the Term, ordinary wear and tear, casualty and condemnation excepted; however, such exception for ordinary wear and tear shall in no way relieve LESSEE of its obligations for repair, replacement and maintenance during the term of this Lease. LESSEE shall also comply with any requirements under this Lease.

23. SALE OF ABANDONED PROPERTY. If, upon the expiration or termination of the Lease Term or LESSEE’s right of possession to the Premises, LESSEE has abandoned any furniture, fixtures, equipment or other personal property at the Premises, then in such event, LESSOR or his representative may enter the Premises and remove and store all property of every kind found therein. For purposes hereof, LESSEE shall not be deemed to have abandoned such personal property unless and until LESSEE fails to remove such personal property for a period of ten (10) days after written notice from LESSOR stating that LESSOR shall consider such personal property to be abandoned unless LESSEE removes it within ten (10) days of such notice. LESSOR shall be entitled to reasonable charges for parking, removing or storing such abandoned or seized property, and may sell same at public or private sale after fifteen (15) days’ written notice of time and place of sale is sent by certified mail, return receipt requested, to LESSEE at the address provided in Paragraph 29 unless LESSEE shall reclaim such property prior to the expiration of such fifteen (15) day period by reimbursing LESSOR for the expenses incurred in parking, removing or storing such property. Sale shall be to the highest cash bidder. Proceeds shall be applied first to costs of sale and then to amounts owed by LESSEE to LESSOR under this Lease, if any, and any remaining amount shall be remitted to LESSEE.

24. SUBORDINATION. LESSEE agrees that its rights under this Lease shall be automatically subordinate to the lien of any existing or future recorded mortgage or deed of trust or other lien applicable to the Premises or its contents, provided that LESSEE’s possession of the Premises and the Building B Parking Spaces shall not be disturbed by LESSOR, the holder of such mortgage, deed of trust or other lien, or any other party so long as LESSEE is not in default of this Lease beyond applicable cure periods. LESSEE shall from time to time upon the request of LESSOR execute and deliver such subordination, non-disturbance and attornment agreements (each, an “SNDA”) as LESSOR’s mortgagee may reasonably require from time to time, provided that LESSEE shall have the right to reasonably object to any provisions therein which are not customarily included in SNDAs or which materially reduce LESSEE’s rights or materially increase LESSEE’s obligations or liabilities under this Lease (provided that any such objections shall not affect the automatic subordination of this Lease provided above). Without limiting the generality of the provisions of this Paragraph 24, LESSEE

21

acknowledges and agrees that LESSOR’s mortgagee shall never have any liability to perform any of LESSOR’s obligations under this lease unless and until such mortgagee forecloses on such mortgage or deed of trust or accepts a deed in lieu thereof, and LESSEE’s remedy shall be against LESSOR only until such time. LESSOR represents and warrants that no lender or other party currently holds a mortgage, deed of trust or other lien against the Premises.

25. TRANSFER OF LESSOR’s RIGHTS. LESSOR shall have the right to transfer and assign, in whole or in part, all and every feature of its rights and obligations hereunder and in the building and property referred to herein, and in such event, the transferee shall be obligated to assume all of the obligations of LESSOR under this Lease arising from and after the date of transfer. Such transfers are to be in all things respected and recognized by LESSEE.

26. NO IMPLIED WARRANTIES. LESSOR’s duties regarding maintenance, repairs, condition of the Premises, security, fitness of the Premises for any particular purpose, or any other duties are limited to those expressly itemized in this Lease and shall not include any implied duties or warranties whatsoever. LESSEE expressly waives any and all implied warranties by LESSOR, including, but not limited to, any warranties that may now exist or later be created by law, or warranties regarding fitness of the Premises, security of the Premises, etc. This waiver is made voluntarily, knowingly, and for good and valuable consideration. It is expressly recognized that were it not for this waiver and disclaimer of warranties and implied duties, the rental hereunder would be higher. Except for any latent defects or improvements which LESSOR is expressly obligated to make pursuant to the terms of this Lease, LESSEE accepts the Premises in their present condition, and by execution of this Lease agrees that the Premises are suitable for LESSEE’s intended use.

27. NO WAIVER. No acceptance of rent by LESSOR or delay by either party in enforcing any obligation shall be construed as a waiver of any default in the performance of any obligation to be undertaken by the other party hereto. A party’s failure to enforce the default provisions hereof in the event of the other party’s default hereunder shall not act as a waiver of such party’s right to enforce the default provisions hereof in the event of a subsequent breach thereof.

No provision of this Lease shall be deemed to have been waived by either party by custom or practice, or otherwise, unless such waiver is in writing, signed by the waiving party.

28. ASSIGNMENT AND SUBLETTING. LESSEE shall have the right to sublease or assign the Lease without Owner’s consent to any affiliated company or any entity resulting from the merger, sale, consolidation or restructuring of LESSEE or in the connection with a sale of the assets used in connection with the business operated by LESSEE at the Building.

22

Except as provided above, LESSEE shall not assign or in any manner transfer this Lease or any estate or interest therein, or allow same to be assigned by operations of law or otherwise, or sublet the Demised Premises or any part thereof, or use or permit same to be used for any other purpose than stated in the use clause hereof without written consent of LESSOR which shall not be unreasonably withheld. LESSOR shall notify LESSEE in writing of LESSOR’s consent or rejection (along with the reasons therefor in reasonable detail) within ten (10) days after LESSEE requests LESSOR’s consent to such transfer. If LESSOR shall consent in writing to such assignment or subletting, such assignment or subletting shall not be for any use more hazardous on account of fire or otherwise, nor for a use that will cause wear and tear more than the use for which the Demised Premises are leased as defined above. The LESSEE shall remain principal obligor to the LESSOR for the full performance of all the terms, conditions and covenants of this Lease by which LESSEE herein is bound; and the acceptance of an assignment or subletting of the Demised Premises by any firm, person or corporation shall be construed as a promise on the part of such assignee or Sub Lessee to be bound by and perform all of the terms, conditions and covenants by which LESSEE is herein bound. No such assignment or subletting shall be construed to constitute a novation. In the event of default by LESSEE while the Demised Premises are assigned or sublet, LESSOR, in addition to any other remedies provided herein (or provided by law), may at LESSOR’s option, collect directly from such assignee or Sub Lessee all rents becoming due to LESSEE under such assignment or subletting and LESSOR may apply such rent against any sums due to LESSOR by LESSEE hereunder. No direct collection by LESSOR from any such assignee or Sub Lessee shall release LESSEE from the further performance of its obligations hereunder.

By the Construction Drawings Date, Lessor shall cause Architect and Engineer to complete the Construction Drawings. “Construction Drawings” herein means fully dimensioned architectural construction drawings and specifications, and any required engineering drawings (including mechanical, electrical, plumbing, air-conditioning, ventilation and heating), prepared using the Space Plan as a basis, showing in detail the Tenant Improvements to be made to the Premises and shall include all details reasonably required in order for Lessor to obtain bids as described in Section IV or otherwise reasonably requested by Architect, Engineer, Lessee or Lessor in order for the Construction Drawings to serve as a basis for contracting the construction of Tenant Improvements.

Lessee shall, within five (5) days after receipt of the Construction Drawings, either approve the Construction Drawings or disapprove of the same with reasonable suggestions for making the same acceptable.

As of February 6, 2009, based on the preliminary drawings and discussions between Lessor and Lessee, the parties have estimated Cost of the Work to be approximately $1,217,810. Lessor and Lessee acknowledge that this amount is just an estimate and will change once the Plans have been completed and approved by Lessor and Lessee, and Lessor has obtained bids acceptable to Lessee.

35

| 1. | Lessor is responsible for the first $500,000 of the Cost of the Work (the “Allowance”).

| 2. | Lessee is responsible for up to the next $400,000 of the Cost of the Work, if the Cost of the Work exceeds $500,000 (the “Lessee’s Contribution”).

| 3. | Lessor is responsible for up to the next $300,000 of the Cost of the Work, if the Cost of the Work exceeds $900,000 (the ,“Additional Allowance”). The Additional Allowance will be recovered by Lessor as TI Rent as set forth in Section 5.2 of the Lease.

Within five (5) days after Lessee notifies Lessor in writing that Lessee has approved the bids for the Tenant Improvements and agreed on the estimated Cost of the Work (the “Funding Period”), Lessee shall deliver to Lessor Lessee’s Contribution and, if applicable, Lessee’s Additional Contribution. Lessor shall deposit the Allowance and, if applicable, the Additional Allowance into the Construction Account, and shall also deposit all funds provided by Lessee into the Construction Account. If, after final completion of the Tenant Improvements, the actual amount of Cost of the Work exceeds both (i) $1,200,000, and (ii) the estimated amount of the Cost of the Work, then Lessee shall pay the difference to Lessor (subject to Lessor’s obligation to contribute 50% of Legal Compliance Costs) within fifteen (15) days after Lessor delivers to Lessee a detailed itemization of the total Cost of the Work, together with supporting invoices. If, after

36

final completion of Tenant Improvements, the actual Cost of the Work is more than $900,000 but less than $1,200,000, Lessor shall notify Lessee in writing of the total Cost of the Work and the actual amount of the Additional Allowance for purposes of calculating the TI Rent. If, after final completion of Tenant Improvements, the actual Cost of the Work is less than $900,000, then Lessor shall promptly refund any unused portion of the Lessee’s Contribution and, if applicable, Lessee’s Additional Contribution, to Lessee from the Construction Account as soon as practicable.

(e) Weekly Meetings; Bank Statements and Records. Lessor and Lessee shall attend weekly status meetings to review the status of the Tenant Improvements and a ledger showing a running total of the Cost of the Work. Lessor agrees to provide copies of all invoices, bank statements (monthly) for the Construction Account, lien waivers and cancelled checks and all invoices, with appropriate supporting information, related to the construction of the Tenant Improvements at such meetings.

(f) Lessee’s Evidence of Financial Commitment. At time of the execution of this Lease, Lessee shall provide to Lessor a letter from Lessee’s bank or other evidence reasonably acceptable to Lessor confirming Lessee’s ability to fund Lessee’s Contribution.

V. Construction.

(a) Lessor to Arrange Work. Provided Lessee is not in violation of the Lease (including this exhibit) beyond applicable cure periods, Lessor shall use reasonable efforts to cause Lessor’s contractor to achieve Substantial Completion of Tenant Improvements as soon as is reasonably practicable, but in any event by November 15, 2009, subject to force majeure. Lessor reserves the right to substitute comparable or better materials and items for those shown in the Plans, so long as they do not materially and adversely affect the appearance, use or operation of the Premises or increase the Cost of the Work or delay Substantial Completion in any material respect.

(b) Substantial Completion and Walk-Through. “Substantial Completion” of the Tenant Improvements shall mean the sufficient completion of Tenant Improvements in accordance with the approved Plans to allow Lessee to use the Premises for the permitted uses and the issuance of any certificate of occupancy required by applicable governmental authorities for the occupancy of the Premises. When Lessor notifies Lessee that Substantial Completion of Tenant Improvements has been achieved, Lessor shall provide a list of the portions of the Tenant Improvements which, notwithstanding such Substantial Completion, have not been completed, and Lessor and Lessee shall perform a joint walk-through inspection in order for Lessee to identify any additional necessary final completion or other “punchlist” items. Neither party shall unreasonably withhold approval concerning such items. If Lessee fails to participate in a walk-through as provided above, or otherwise fails to object to Lessor’s notice of Substantial Completion in writing within five (5) business days thereafter specifying in detail the items of work needed to be performed to achieve Substantial Completion, Lessee shall be deemed conclusively to have agreed that Substantial Completion of Tenant Improvements has occurred on the date provided in Lessor’s notice. If there is any dispute as to whether Substantial Completion of Tenant Improvements has occurred, Lessor may request a good faith decision by the Architect which shall be final and binding on the parties.

(c) Final Completion. Substantial Completion shall not prejudice Lessee’s rights to require full completion of any remaining items of Tenant Improvements, which Lessor shall cause to be completed as soon after Substantial Completion as is reasonably practicable, but in no event later than thirty (30) days after Substantial Completion has occurred, subject to force majeure; provided, however, if any such punchlist item is not reasonably capable of being completed within thirty (30) days after Substantial Completion, Lessor shall not be in default of its obligation to complete such punchlist items within thirty (30) days after Substantial Completion as long as Lessor has commenced to correct such items within such thirty (30) day period and diligently, and in good faith, pursues completion of such items in a timely manner. If Lessor notifies Lessee in writing that the Tenant Improvements are fully completed, and Lessee fails to object thereto in writing within ten (10) business days thereafter specifying in detail the items of work needed to be completed and the nature of work needed to complete such items, Lessee shall be deemed conclusively to have accepted Tenant Improvements as fully completed (or such portions thereof as to which Lessee has not so objected). If Lessee timely notifies Lessor in writing that it objects to specific items of the Tenant Improvements not being fully complete, Lessor shall withhold a reasonable amount necessary to cause the applicable contractor to fully complete such incomplete items, and Lessor shall timely cause such incomplete items to be fully completed, but Lessor shall otherwise have the right to pay all contractors all remaining amounts due under the construction contracts for the completion of the Tenant Improvements upon the expiration of the 10-business day period described above. Lessor shall withhold the final payment for the incomplete items until such time as Lessee has reasonably agreed to Lessor’s determination that the Tenant Improvements have been finally completed, provided that Lessee shall be deemed to have agreed with Lessor’s determination if Lessee does not object thereto with such 10 business day period. Lessor shall assign all warranties for the Tenant Improvements to Lessee upon final completion thereof.

(d) Lessor’s Role. The parties acknowledge that neither Lessor nor its managing agent is an architect or engineer, and that the Tenant Improvements will be designed and constructed by independent architects, engineers and contractors. Lessor does not guarantee that the Plans or Tenant Improvements will be free from errors, omissions or defects, and shall have no liability therefor.

VI. Lessee’s Contractors. If Lessee should desire to enter the Premises or authorize its contractors or consultants to do so prior to the Commencement Date of the Lease, to install cabling, equipment, furniture or fixtures, Lessor shall permit such entry, and shall cause its contractor(s) to reasonably cooperate with such entry, provided that:

(a) Lessee and its contractors and consultants who may enter the Premises (collectively, “Lessee’s Contractors”) work in harmony with and do not unreasonably disturb or interfere with Lessor’s architects, engineers, contractors, workmen, mechanics or other agents or independent contractors in the performance of their work (collectively, “Lessor’s Contractors”), it being understood and agreed that if Lessee or any of Lessee’s Contractors does unreasonably disturb or interfere with Lessor or any of Lessor’s Contractors, then Lessor may, with notice, refuse admittance to Lessee or Lessee’s Contractors causing such disturbance or interference; and

(b) Lessee has provided Lessor proof of the insurance Lessee is required to carry under this Lease, and Lessee’s Contractors have provided Lessor sufficient evidence that each is covered under such worker’s compensation, general liability, automobile liability and property damage insurance as Lessor may reasonably request for its protection.

Lessor shall not be liable for any injury, loss or damage to any of Lessee’s installations made prior to the Commencement Date and not installed by Lessor. Lessee shall defend, indemnify and hold harmless Lessor and Lessor’s Contractors from and against any and all costs, expenses (including reasonable attorney’s fees), claims, liabilities and causes of action arising out of or in connection with work performed in the Premises by or on behalf of Lessee (but excluding work performed by Lessor or Lessor’s Contractors). Lessor is not responsible for improvements, cabling, equipment, cabinets or fixtures not installed by Lessor.

RENEWAL OPTION

At the end of original Lease Term, Lessee, but not any sublessee, will have up to two (2) options to renew the Lease as to all of the Premises (or, if the Premises consists of more than one building in the Business Park, a portion of the Premises, provided that such renewal cannot be exercised for less than all of Building B or all of the portion of the Premises located in any other building in the Business Park) for a period of Five (5) Years each (each hereinafter referred to as a “Renewal Term”); provided that as a condition to each such Renewal Term, Lessee must deliver to Lessor written notice of Lessee’s exercise of such right of renewal at least 270 days, but no more than one year, prior to the end of the then-current Lease Term or Renewal Term. Each Renewal Term shall be on the same terms and conditions as are set forth in this Lease, except the Basic Rent for each Renewal Term will be at the then determined Fair Market Rental Rate determined as set forth below. Lessee shall not have such right of renewal if Lessee is in default beyond any applicable cure period allowed by the Lease, either at the time of such notice of renewal or at the end of the Lease Term. Except as provided below when, Lessee timely exercises its option, Lessee will definitely be committed to lease the Premises for the Renewal Term, with Basic Rent being the Fair Market Rental Rate determined as set forth below.

Fair Market Rental Rate. As used in this Addendum, the term ‘‘Fair Market Rental Rate” shall mean the annual rental rate per square foot of rentable area then being charged as Basic Rent in arm’s length, bona fide negotiations for comparable buildings of similar quality, size, location, age and use in the Austin, Texas market, for space comparable to the space for which the Fair Market Rental Rate is being determined (taking into consideration use, location, floor level within the applicable building, extent of leasehold improvements existing, remodeling credits or allowances granted, quality, age and location of the applicable building, rental concessions {such as abatements or lease assumptions}, the provision of free or paid unassigned parking, the time the particular rate under consideration became effective, size of tenant, creditworthiness of

57

tenant, the then current operating expenses, relative services provided, and any other relevant factors). LESSOR shall advise LESSEE in writing of the Fair Market Rental Rate proposed by LESSOR in good faith within thirty (30) days after LESSEE has delivered its written notice to LESSOR exercising the renewal option (or such other option as may be described in other exhibits or addendums to this Lease, as applicable). LESSEE shall elect, within thirty (30) days thereafter, in a writing delivered to LESSOR to either (i) accept LESSOR’s determination of the Fair Market Rental Rate (in which case the option so exercised shall be deemed unconditionally exercised for the applicable term at such rate), (ii) reject LESSOR’s determination of the Fair Market Rental Rate and retract its exercise of the renewal option, or (iii) reject LESSOR’s determination of the Fair Market Rental Rate and elect to negotiate with LESSOR for up to an additional ten (10) day period in order to reach agreement on the Fair Market Rental Rate. If LESSEE fails to deliver a written election to LESSOR within such thirty (30) day period, LESSEE shall be deemed to have elected (iii). If LESSEE elects or is deemed to have elected (iii), then LESSOR and LESSEE shall place in a separate sealed envelope such party’s final proposal as to the Fair Market Rental Rate, and shall meet with each other within five (5) business days after LESSEE elects, or is deemed to have elected, (iii) above, whereupon each party shall exchange the sealed envelopes and open such envelopes in each other’s presence, and each party’s proposed Fair Market Rental Rate shall be recorded. LESSOR and LESSEE shall negotiate in good faith for an additional period of up to ten (10) days in order to reach agreement on the Fair Market Rental Rate. At any time within such additional ten (10) day period, LESSEE may elect, by delivering written notice to LESSOR, to proceed with the arbitration process described below to determine the Fair Market Rental Rate with respect to the Premises (or such other space, as applicable). If, at the end of this additional ten (10) day period, LESSEE and LESSOR have not agreed on the Fair Market Rental Rate and LESSEE has not elected to proceed with the arbitration process described below, then LESSEE shall be deemed to have retracted its exercise of the Renewal Option.

58

Within ten (10) days after LESSOR’s receipt of LESSEE’s notice invoking an arbitration proceeding, LESSOR and LESSEE shall each nominate and appoint a Qualified Broker to determine the Fair Market Rental Rate for the Leased Premises (or such other space, as applicable). Neither LESSOR nor LESSEE shall consult with such Qualified Broker as to his or her opinion as to Fair Market Rental Rate prior to the appointment. The determination of the Qualified Brokers shall be limited solely to the issue of whether LESSOR’s or LESSEE’s submitted Fair Market Rental Rate for the Leased Premises (or such other space) is the closest to the actual Fair Market Rental Rate for the Leased Premises (or such other space) as determined by the Qualified Broker, taking into account the requirements hereof. The two (2) Qualified Brokers shall afford to LESSOR and LESSEE the right, which right shall expire five (5) business days following the appointment of the second of the two (2) Qualified Brokers, to submit (with a copy to the other party hereto) any market data and additional information that such party deems relevant to the determination of the Fair Market Rental Rate (the “FMRR Data”), and each party may submit to each Qualified Broker in writing one (1) reply to the other party’s FMRR Data within five (5) business days after receipt of the FMRR Data. The Qualified Brokers shall, with all possible speed, make their respective determinations and deliver a written report thereof to LESSOR and LESSEE within thirty (30) days after their appointment. Such Qualified Brokers may hold such hearings and require such briefs as the Qualified Broker, in his or her sole discretion, determines is necessary. In the event that the two Qualified Brokers are unable to agree on either the LESSOR’s or the LESSEE’s proposal within such thirty (30) day period, then the two (2) Qualified Brokers shall within ten (10) days after both of such Qualified Brokers have submitted their written reports to LESSOR and LESSEE select by mutual agreement a third (3rd) Qualified Broker and give written notice of such appointment to LESSOR and LESSEE. If the two (2) Qualified Brokers fail to agree upon the third Qualified Broker within said ten (10) day period, a third (3rd) Qualified Broker shall be selected by mutual agreement of LESSOR and LESSEE within a further period of ten (10) days, failing which, either LESSOR or LESSEE may elect to have the third (3rd) Qualified Broker appointed by the President of the Austin Chapter of the American Arbitration Association or its successor organization. The third (3rd) Qualified Broker shall be instructed to fairly and impartially determine whether the LESSOR’s or the LESSEE’s proposal is the closest to the actual Fair Market Rental Rate for the Leased Premises, taking into account the requirements

59

hereof, and the determination so selected, which shall be due no later than fifteen (15) days following his or her appointment, shall be binding upon LESSOR and LESSEE and shall be the Fair Market Rental Rate for purposes of the Premises. LESSOR and LESSEE shall pay the fees and expenses of the Qualified Broker it appoints, and the fees and expenses of the third (3rd) Qualified Broker shall be divided equally between LESSOR and LESSEE. If any Qualified Broker appointed as aforesaid shall thereafter become unable or unwilling to act, such Qualified Broker’s successor shall be appointed in the same manner as provided in this Section for the appointment of that Qualified Broker.

The parties understand, stipulate and agree that there will be no compromise, modification or averaging of the LESSOR’s and LESSEE’s proposals for the Fair Market Rental Rate, and the Qualified Brokers must select one or the other, and that the proposed Fair Market Rental Rate selected by the foregoing arbitration procedure shall be final, binding, conclusive and effective on LESSOR and LESSEE for purposes under this Lease, and same shall not be subject to judicial review, mediation or any other legal proceeding.

ADDENDUM #10

LIMITED RIGHT OF FIRST REFUSAL

Subject to Lessee not being in default beyond applicable cure periods, during the Lease Term (including any Renewal Term), Lessor grants to Lessee a continuous right of first refusal (the “Right of First Refusal”) exercisable as hereinafter set forth, to lease any space in any of the other Buildings located in the Business Park (the “Refusal Space”). All rights of Lessee to lease the Refusal Space pursuant to the Right of First Refusal shall be applicable to the entire Refusal Space or to any portion thereof which may become available. The Right of First Refusal shall be as follows:

1. Upon Lessor’s receipt of a signed Letter of Intent from a third party Lessee for the lease of all or any portion of the Refusal Space that Lessor is willing to accept (but in any event prior to entering into any lease or other occupancy agreement affecting the Refusal Space), Lessor shall notify the Lessee in writing (the “Offer Notice”). The Offer Notice shall include a true, correct and complete copy of any such signed Letter of Intent or the terms upon which Lessor is willing to enter into a lease for such Refusal Space, and designate all or such portion of the Refusal Space covered by the Letter of Intent (the “Offered Refusal Space”). Lessee may exercise the Right of First Refusal and include the Offered Refusal Space, or any other unleased portion of the Refusal Space under this Lease, upon the terms and conditions as set forth in the Offer Notice by delivering to Lessor written notice of Lessee’s election (the “Acceptance Notice”) on or before fifteen (15) days after the date of Lessee’s receipt of the Offer Notice; provided, however, if the lease term set forth in the Offer Notice is not coterminous with the Lease Term, said terms shall be pro-rated and the expiration date will be made coterminous with the Lease Term.

2. In the event Lessor does not receive Lessee’s Acceptance Notice as to the Offered Refusal Space as described in the Offer Notice within said fifteen (15) day period, Lessee shall be deemed to have waived its Right of First Refusal with respect to such Offer Notice without further notice to Lessee and Lessor shall be free to lease the Offered Refusal Space to a third party on the same terms and conditions as set forth in the Offer Notice, provided that Lessor consummate such lease within one hundred eighty (180) days after the date the Offer Notice was delivered to Lessee. Lessee’s failure to give Lessor a Lessee’s Acceptance Notice as to any Offered Refusal Space described in an Offer Notice shall be deemed a waiver and release of Lessee’s Right of First Refusal as to the Offered Refusal Space designated in the Offer Notice. If Lessor desires to lease the Offered Refusal Space on terms and/or conditions materially different from those contained in the Offer Notice or after the expiration of such 180 day period, Lessor must again offer the Offered Refusal Space to Lessee on such different terms and/or conditions, if applicable, and Lessee may exercise the Right of First Refusal and include the Offered Refusal Space on such different terms and/or conditions, if applicable, by delivering to Lessor an Acceptance Notice on or before fifteen (15) days after the date of Lessee’s receipt of the different terms and conditions.

75

3. All Refusal Space leased by Lessee pursuant to the Right of First Refusal shall be for a term which is coterminous with the initial Lease Term and any renewal or extension thereof. Except for any terms or conditions specified in the Offer Notice, including without limitation the commencement date and the rental rates, the lease conditions for such additional space shall be the same as for the original Premises.

4. The term Premises, as used in this Lease, shall include all expansions thereof that may occur from time to time pursuant to this Right of First Refusal.

5. Upon the exercise of the Refusal Option pursuant to the terms hereof, Lessor and Lessee shall execute an instrument delineating and describing the any Refusal Space leased by Lessee and thereby added to the Premises.”

6. SUBJECT TO OUTSTANDING COMMITMENTS. The Right of First Refusal granted herein shall be subject to the renewal options, expansion options, and/or preferential rights to lease, if any, held by the then current lessee, if any, of such additional space or portion thereof.

7. TERMINATION UPON DEFAULT. Lessee shall not be entitled to exercise the Right of First Refusal following the occurrence, and during the continuance, of any event of default under the Lease beyond applicable cure periods.

76

ADDENDUM #11

RIGHT OF FIRST REFUSAL TO PURCHASE

Subject to Lessee not being in default and otherwise being in full compliance with the terms of this Lease, Lessor hereby grants to Lessee a continuing right of first refusal (the “Right of First Refusal to Purchase”) to purchase the Premises or the Business Park under the following terms and conditions:

(a) | During the Term of this Lease, upon Lessor’s receipt of a signed Letter of Intent from third party purchaser of all or part of the Business Park (but in any event prior to entering into any binding purchase agreement for all or part of the Business Park), Lessor will deliver a written notice to Lessee (the “Offer Notice”). The Offer Notice shall include a true, correct and complete copy of any such signed Letter of Intent (or shall specify in reasonable detail the terms of the offer which Lessor has deemed acceptable) and designate all or such portion of the Business Park covered by the Letter of Intent (the “Offered Refusal Property”).

(b) | Lessee will have ten (10) days from the date of the Offer Notice to exercise the Right of First Refusal to Purchase to purchase the Business Park, or Building B, on the same terms as set forth in the Offer Notice. In order to exercise the Right of First Refusal to Purchase, Lessee must deliver to Lessor, on or before ten (10) days from Lessee’s receipt of the Offer Notice, a written notice exercising Lessee’s Right of First Refusal to Purchase to purchase the Business Park or Building B (the “Exercise Notice”). If Lessee fails to timely deliver an Exercise Notice to Lessor, then Lessee will be deemed to have waived and released its Right of First Refusal to purchase the Business Park or Building B, and thereafter, Lessor will have the right to sell the Business Park or Building B to a third party on the terms set forth in the Offer Notice, without material deviation, within one hundred eighty (180) days after Lessee waives (or is deemed to have waived) its rights hereunder. If Lessee timely delivers an Exercise Notice to Lessor, then the parties will promptly commence the negotiation and execution of a definitive agreement for the purchase and sale of the Business Park or Building B, as applicable (the “Definitive Agreement”). The Definitive Agreement will include (i) that the purchase price of the Business Park or Building B will be the price set forth in the Offer Notice and will be paid in cash at the closing, (ii) that upon execution of the Definitive Agreement, Lessee will be obligated to deliver to the escrow agent an earnest money deposit in an amount equal to 5% of the purchase price (which shall be non-reimbursable subject only to Lessee’s title and survey review and the satisfaction of Lessee’s lender’s due diligence requirements, or in the event of a default by Lessor thereunder), (iii) that the Business Park or Building B, as applicable, will be sold “AS IS, WHERE IS” and WITH ALL FAULTS”, and Lessor will not make any warranties and representations regarding the Premises, other than Lessor’s special warranty of title to be delivered at closing, and (iv) such other terms and conditions as are reasonably and mutually acceptable to Lessor and Lessee, and normal and customary for the purchase and sale of properties similar to the Business Park. If Lessor and Lessee, using commercially reasonable efforts and acting in good faith, are unable to negotiate and execute a Definitive Agreement within twenty (20) days from the date Lessee delivers the Exercise Notice to Lessor, then Lessee will be deemed not to have exercised the Right of First Refusal to Purchase, Lessee will be deemed to have waived and released its Right of First Refusal to Purchase, and Lessor will have the right to sell the Business Park on the terms set forth in the Offer Notice, without material deviation, within one hundred eighty (180) days after Lessee waives (or is deemed to have waived) its rights hereunder.

77

(c) | If Lessee fails to timely exercise the Right of First Refusal to Purchase, or is deemed to have waived and released the Right of First Refusal to Purchase as set forth above, and if Lessor desires to sell the Business Park on terms materially less favorable to Lessor than those specified in the Offer Notice, or after the expiration of such 180-day period, Lessor shall again deliver an Offer Notice to Lessee., and in such event, Lessee will have the right to exercise this Right of First Refusal to Purchase in the same manner as set forth above.

(d) | Lessee acknowledges that the entire Business Park is a single platted lot. If Lessee desires to only purchase Building B, Lessor agrees to subdivide, at Lessee’s sole cost and expense, the Business Park into four lots, with each building in the Business Park located on a separate lot, and containing such mutual access easements and other easements as Lessor and Lessee may reasonably require. The completion and filing of the subdivision plat shall be a condition to closing.
