Premises or provide any allowances therefor. Landlord shall provide an allowance (the Tenant Allowance) for
the Tenants improvements (the Tenant Improvements) in connection with the Leased Premises including, but not limited to, those reasonable costs and expenses associated with the preparation of architectural and mechanical plans,
consulting fees, costs of equipment and other design or construction related fees and expenses relating to such Tenant Improvements, in an amount up to $284,135 ($6.50 per rentable square foot within the Leased Premises), provided that Tenant must

fee pursuant to the Lease, or otherwise, relating to the Tenant Improvements.



6. As of the Effective Date, Section 3.1 of the Lease shall be amended and restated in its entirety to read as follows:



Security Deposit. Upon execution of the First Amendment, Lessee shall deliver to Lessor an irrevocable, unconditional letter of credit in the
amount of $657,444.00 issued by a national bank having a branch office in Austin, Texas reasonably acceptable to Lessor in form and substance reasonably satisfactory to Lessor (the Initial Letter of Credit). The form of letter of
credit shall also be subject to the reasonable approval of Lessees lender. The Initial Letter of Credit, and any Replacement Letter of Credit (defined below) (i) shall have a term which shall extend until at least thirty (30) days after the
expiration of the Term, (ii) be payable at sight upon presentment of a sight draft accompanied by a certificate of Lessor stating either that Lessee is in default under this Lease or that Lessor is otherwise permitted to draw upon such Letter of
Credit under the express terms of this Lease, and (iii) permit multiple draws. If (x) Lessee desires to change the issuing bank with respect to the Initial Letter of Credit or, if applicable, any Replacement Letter of Credit, or (y) within ten (10)
days following written notice by Lessor to Lessee that, in the reasonable judgment of Lessor, the bank issuing the Initial Letter of Credit or any Replacement Letter of Credit, is or may become no longer able to honor the obligations in such Letter
of Credit, or (z) such bank delivers written notice to Lessor that it is not willing to renew the applicable Letter of Credit, Lessee shall deliver to Lessor, at least thirty (30) days prior to the expiration of the applicable Letter of Credit, a
replacement letter of credit in the amount of $657,444.00 (each, a Replacement Letter of Credit) issued by a national bank having a branch office in Austin, Texas reasonably acceptable to Lessor in form and substance similar to
the Initial Letter of Credit. The Initial Letter of Credit and each Replacement Letter of Credit are sometimes collectively and individually referred to herein as Letter of Credit. If Lessee fails to deliver a Replacement Letter
of Credit as required hereunder, Lessor shall have the right to require payment of the entire amount under the Letter of Credit, and hold the proceeds thereof as a cash Security Deposit hereunder.



Lessee agrees that upon any non-monetary default by Lessee under the terms
and provisions of the Lease, which default remains uncured thirty (30) days after Lessor gives Lessee written notice of such default, Lessor shall have the right to receive payment of the entire amount under the Letter of Credit, and such amounts
received by Lessor shall be held by Lessor as a cash Security Deposit. The Letter of Credit and any cash Security Deposit shall be held by Lessor as security for the faithful performance of all the terms of this Lease to be observed and performed by
Lessee. Neither the Letter of Credit nor any cash Security Deposit shall be mortgaged, assigned, transferred or encumbered by Lessee and any such act on the part of Lessee shall be



3



---

without force and effect and shall not be binding upon Lessor. Lessee shall cause the Letter of Credit or any cash
Security Deposit to be maintained for the time period required hereunder in the amount set forth in this Section 3.1.



If Base Rent or Additional Rent payable hereunder shall be overdue and unpaid or should Lessor make any payment on behalf of the Lessee, or Lessee shall
fail to perform any of the terms of this Lease, then Lessor may, at its option and without notice or prejudice to any other remedy which Lessor may have on account thereof, (i) if Lessor then holds a Letter of Credit (and not a cash Security
Deposit), require payment of the entire amount under the Letter of Credit and such amounts paid to Lessor shall be held by Lessor as a cash Security Deposit hereunder; or (ii) if Lessor then holds a cash Security Deposit, appropriate and apply the
entire Security Deposit or so much thereof as may be necessary to compensate Lessor toward the payment of Base Rent, Additional Rent or other sums or loss or damage sustained by Lessor due to such breach by Lessee. Within ten (10) days after written
request by Lessor, Lessee shall restore the cash Security Deposit to the amount stated above, or in lieu thereof, provide a new Letter of Credit in accordance with the first paragraph of this Section 3.1. Notwithstanding the foregoing, upon the
proper application by Lessor of all or any portion of the cash Security Deposit (with or without notice thereof to Lessee) to compensate Lessor for a failure by Lessee to pay any Base Rent or Additional Rent when due or to perform any other
obligation hereunder, and until Lessee shall have restored the cash Security Deposit to the amount required by this Section 3.1 or shall have provided a new Letter of Credit in accordance with the first paragraph of this Section 3.1, Lessee shall be
deemed to be in default in the payment of Additional Rent for purposes of Section 23.1(a) hereof. So long as Lessee shall not be in default of its obligations under this Lease, Lessor shall return the cash Security Deposit, or so much thereof as
shall have not theretofore been applied in accordance with the terms of this Section 3.1, or the Letter of Credit, as the case may be, to Lessee promptly following the expiration or earlier termination of the Term of this Lease and the surrender of
possession of the Leased Premises by Lessee to Lessor in accordance with the terms of this Lease. While Lessor holds any cash Security Deposit, Lessor shall have no obligation to pay interest on the same and shall have the right to commingle the
same with Lessors other funds. If Lessor conveys Lessors interest under this Lease, (i) any cash Security Deposit, or any part thereof not previously applied, shall be turned over by Lessor to Lessors transferee and (ii) any Letter
of Credit shall be turned over by Lessor to Lessors transferee to the extent such Letter of Credit is assignable, and if such Letter of Credit is not assignable, Lessee shall upon ten (10) days prior written request, cause a Replacement
Letter of Credit to be issued in the name of Lessors transferee, and Lessee shall look solely to such transferee for proper application of any cash Security Deposit and any Letter of Credit in accordance with the terms of this Section 3.1 and
the return thereof in accordance herewith. Lessor or Lessors transferee shall pay any reasonable fees associated with the assignment of any Letter of Credit, or issuance of a Replacement Letter of Credit, to Lessors transferee, such fees
not to exceed $1,500.00, and Lessee shall be responsible for any such fees in excess of $1,500.00. The holder of a mortgage on the Property shall not be responsible to Lessee for the return or application of the Security Deposit, whether or not it
succeeds to the position of Lessor hereunder, unless such holder actually receives the Security Deposit.

appropriate.
