 SUBLEASE 
  

This SUBLEASE is dated as of the Execution Date (as defined in Schedule 1) between SigmaTel, Inc. (“Sublessor”) and Texas Networking, Inc.
(“Sublessee”). 
  
 1.    MASTER LEASE

  
 1.1    Sublessor is the tenant under the
Master Lease (as defined in Schedule 1) wherein Landlord (as defined in Schedule 1) leased to Sublessor the Leased Premises (as defined in Schedule 1) in the Building (as defined in Schedule 1). 
  
 This Sublease is subject and subordinate to the Master Lease, a copy of which
is attached hereto as Exhibit “A”, and made a part hereof for all purposes as if fully set forth herein, except for Section 3.05 of the Master Lease, Paragraph 3 of Exhibit G to the Master Lease, and the Tenant Work Letter attached
the Master Lease, which provisions shall not be incorporated herein and shall be referred to herein as the “Excluded Provisions.” Sublessee agrees to assume all provisions of the Master Lease, except for the Excluded Provisions. Except as
specified to the contrary in this Sublease, all defined terms in the Master Lease have the same meanings in this Sublease. If there is a conflict between the terms of the Master Lease and this Sublease, the terms of the Sublease control, it being
expressly understood by the parties that the terms of the Sublease will in no way diminish or minimize the terms and obligations of the Master Lease. 
  
 1.2    With the exception of the Excluded Provisions, Sublessee hereby covenants and agrees to comply with and perform all obligations
of Sublessor under the Master Lease pertaining to the Subleased Premises (as hereinafter defined), including, without limitation, all repair obligations, all insurance obligations (and all insurance required to be maintained by Sublessee shall name
both the Sublessor and the Landlord as additional insureds), all obligations to pay utility charges and taxes, and all indemnification obligations of Sublessor thereunder, and any liability accruing from failure to pay same when due thereunder.
Sublessee agrees that whenever the consent of Landlord is required under the terms of the Master Lease with respect to any action, Sublessee shall obtain the consent of Sublessor and of Landlord prior to taking such action. Sublessee hereby
covenants and agrees to promptly deliver to Sublessor copies of any and all notices or other correspondence received by Sublessee from Landlord that affects Sublessor and further agrees to so deliver same in accordance with 13.1 below. 

 
 1.3    Sublessee shall not have the right to exercise
any of Sublessor’s options or elections permitted or authorized under the Master Lease, or to institute any action or proceeding against Landlord for the enforcement of the Master Lease. If Landlord shall default in the performance of any of
its obligations under the Master Lease, Sublessor shall, upon the written request of Sublessee and at Sublessee’s sole cost and expense, use its diligent good faith efforts to enforce the Master Lease and obtain Landlord’s compliance with
its obligations thereunder. In the event that the default of the Master 
  

 2 









 Lease is the failure to provide required services, and if Sublessor at its option chooses not to provide such services,
Sublessee may only deal directly with the Landlord in an effort to obtain such services and Sublessor shall have no liability for the provision of services or the enforcement thereof. 
  
 2.    SUBLEASED PREMISES 
  

2.1    In accordance with the terms and conditions set forth in this Sublease, Sublessor hereby subleases to Sublessee, and
Sublessee hereby takes and sublets from Sublessor, the Subleased Premises (as defined in Schedule 1). 
  
 3.    REPRESENTATIONS AND WARRANTIES 
  
 3.1    Sublessor represents to Sublessee that: 
  

	 	i.	 	except as expressly stated herein, the Master Lease is unmodified and in full force and effect, and Sublessor’s leasehold estate with respect to the Subleased Premises has not
been assigned, mortgaged, pledged, encumbered, or otherwise transferred or sublet, in whole or in part; 

  

	 	ii.	 	the Master Lease evidences the entire written agreement with respect to the Subleased Premises between Sublessor and Landlord; 

  

	 	iii.	 	all rent and additional rent billed to date and payable by Sublessor, as “Tenant” under the Master Lease, has been paid; 

  

	 	iv.	 	Sublessor has received no written notice from Landlord of default by Sublessor under the Master Lease which remains uncured; and 

  

	 	v.	 	Sublessor, to the best of Sublessor’s knowledge, is not in default under the Master Lease. 

  

	 	3.2	 	Sublessee represents to Sublessor that: 

  

	 	i.	 	Sublessee is in good standing and fully authorized to do business in Texas; 

  

	 	ii.	 	Sublessee is in compliance with all applicable laws, rules, and regulations, fully licensed, authorized, and empowered to perform its respective rights and obligations under this

 3 









 iii.    Sublessee’s financial statements are prepared in accordance with
Generally Accepted Accounting Principles and are consistent with financial statements from prior periods. 
  
 The aforesaid representations shall be deemed repeated at and as of the Commencement Date (as defined in Schedule 1). 
  
 4.    TERM 
  
 4.1    The term of this Sublease shall commence on the
Commencement Date and shall continue, unless otherwise sooner terminated in accordance with provisions of this Sublease or at law, until the Expiration Date (as defined in Schedule 1). The term of this Sublease shall be referred to herein as the
“Term”. If for any reason Sublessor does not deliver possession of the Subleased Premises (“Possession”) to Sublessee on the Commencement Date, Sublessor shall not be subject to any liability for such failure and
the validity of this Sublease shall not be impaired, but not withstanding anything herein to the contrary, Rent (as defined in Schedule 1) shall abate and need not be paid until the delivery of Possession. 
  
 5.    RENT 
  
 5.1    Except as otherwise provided herein in Section
11.1, Sublessee shall pay to Sublessor on the first day of each month of the Term the Rent and Additional Rent (as hereinafter defined) without deduction, abatement, setoff, notice, or demand, at Sublessor’s Address for Rent (as defined in
Schedule 1), or at such other place as Sublessor shall designate from time to time by notice to Sublessee, in lawful money of the United States of America. 
  
 Sublessee shall pay to Sublessor, the Rent for the first month of the Term, upon the execution of this Sublease. If the Term begins or ends on a day other
than the first or last day of a month, the rent for the partial months shall be prorated on a per diem basis. 
  
 5.2    In addition to Rent and any other sums which Sublessee may be obligated to pay pursuant to any other provision of this
Sublease, Sublessee shall pay to Sublessor as additional rent hereunder all amounts defined as (“Additional Rent”) in the Master Lease under Section 3.02 and other relevant Sections. 
  
 For purposes of this Sublease, the amounts payable by Sublessee pursuant to
this Section 5.2 and Section 9 below are hereinafter referred to as “Additional Rent”. 
  
 6.    SECURITY 
  
 6.1    Upon execution of this Sublease, in addition to the other amounts described in Section 5, Sublessee shall deliver to Sublessor, either by (i) an irrevocable letter of credit 
  

 4 









 payable upon demand to Sublessor or (ii) cash, the amount of the Security Deposit (as defined in Schedule 1) as partial
consideration for this Sublease and as security for the faithful performance and observance by Sublessee of the terms, provisions, covenants and conditions of this Sublease. If the Security Deposit is in cash, Sublessor agrees to place the Security
Deposit in an interest bearing account, with the interest accruing to the benefit of Sublessee, payable semi-annually. It is agreed that in the event Sublessee defaults beyond any applicable notice and grace period provided herein for the cure
thereof in respect of any of the terms, provisions, covenants and conditions of this Sublease, including, but not limited to, the payment of Rent and Additional Rent, Sublessor may, upon written notice to Sublessee, use, apply or retain the whole or
any part of the security so deposited, or as the case may be, make demand upon the issuing bank of the irrevocable letter of credit for the proceeds, to the extent required for the payment of any Rent and Additional Rent or any other sum as to which
Sublessee is in default or for any sum which Sublessor may expend or may be required to expend by reason of Sublessee’s default in respect of any of the terms, provisions, covenants and conditions of this Sublease, including, but not limited
to, any damages or deficiency accrued before or after summary proceeding or other re-entry by Sublessor. In the event Sublessor applies or retains any portion or all of the Security Deposit, Sublessee shall forthwith restore the amount so applied or
retained so that at all times the amount deposited shall be the amount set forth above. 
  
 In the event that Sublessee shall fully and faithfully comply with all of the terms, provisions, covenants and conditions of this Sublease, and shall not be in default of the Sublease in the final few months of the
Term, and (i) the Security Deposit was paid in cash, one-half (1/2) of the Security Deposit shall be applied to the last month’s Rent and the remaining one-half (1/2) of the Security Deposit shall be returned to Sublessee after the Expiration
Date and after delivery of entire possession of the Subleased Premises to Sublessor, or (ii) the Security Deposit was made by an irrevocable letter of credit, the irrevocable letter of credit shall be reduced by one-half (1/2) of the Security
Deposit, Sublessee shall continue to pay Rent throughout the Term, and the remaining irrevocable letter of credit representing one-half (1/2) of the Security Deposit shall terminate after the Expiration Date and after delivery of entire possession
of the Subleased Premises to Sublessor. In the event of any assignment of Sublessor’s interest in the Master Lease, Sublessor shall have the right to transfer the Security Deposit to the assignee and, provided such assignee acknowledges, in
writing, receipt of and liability to Sublessee for such Security Deposit, Sublessor shall thereupon be released by Sublessee from all liability for the return of such Security Deposit if paid in cash; and Sublessee agrees to look solely to such
assignee for the return of said Security Deposit; and it is agreed that the provisions hereof shall apply to every assignment made of the Security Deposit to any such assignee. Sublessee further covenants that it will not assign or encumber or
attempt to assign or encumber the monies, if paid in cash, deposited herein as the Security Deposit and that neither Sublessor nor its successors or assigns shall be bound by any such assignment, encumbrance, attempted assignment or attempted
encumbrance. 
  

 5 









 6.2    Upon execution of the Sublease, Sublessee shall provide to Sublessor the
unconditional personal guaranty of Jonah Yokubaitis, Ron Yokubaitis, and Carolyn Yokubaitis which guaranty shall be substantially in the form attached hereto as Exhibit “B”, which shall secure the obligation of Sublessee hereunder, and
which shall be effective until June 30, 2002. 
  
 7.    USE
OF THE SUBLEASED PREMISES 
  
 7.1    The
Subleased Premises shall be used and occupied for general business office purposes and incidental purposes only and otherwise to the extent permitted pursuant to the terms of the Master Lease and for no other use or purpose. 
  
 8.    ASSIGNMENT AND SUBLETTING 
  
 8.1    In addition to satisfying the requirements of the
Master Lease, Sublessee shall not, without the prior written consent of the Sublessor, mortgage, pledge, encumber, transfer or sublet, by operation of law or otherwise, or in any manner transfer this Sublease, or any part thereof or any interest of
Sublessee hereunder or sublet or permit the Subleased Premises or any part thereof to be used or occupied by others. Sublessor’s consent under this Section 8.1 shall not be unreasonably withheld; provided, however, in granting or withholding
its consent, Sublessor shall be entitled to take into consideration all relevant factors including without limitation, the credit worthiness of the proposes subtenant or assignee, the nature of the business and business reputation of the proposed
subtenant or assignee (including without limitation proposed uses and parking requirements), the term of the sublease or assignment and the rental rate under the proposed sublease or assignment. Sublessor may, if it so elects, withhold its consent
if the proposed subtenant or assignee is a government entity. Sublessor may withhold or condition its consent subject to execution and delivery of an appropriate sublease or assignment which shall include such terms and conditions as Sublessor may
reasonably require including provisions for notice to Sublessor, prohibition on further assignment or subleasing without Sublessor’s consent and indemnification of Sublessor by the subtenant or assignee. Sublessor may withhold its consent to
any proposed assignment or sublease if an Event of Default has occurred and is continuing, or an event has occurred which, with the giving of notice, or the passage of time, or both, could constitute any Event of Default. Any such assignment,
subletting, or permission to occupy without such consent by Sublessor shall be void. Any such consent by Sublessor of any such assignment, subletting, or permission to occupy shall not release Sublessee or Guarantors from any of Sublessee’s or
Guarantors’ obligations hereunder or be deemed to be a consent to any subsequent assignment, subletting, occupation or use by another person. 
  
 9.    TENANT SURCHARGES 
  

 6 









 9.1    “Tenant Surcharges” shall mean any and all amounts (other than Rent
and Sublessee’s share of increases in Operating Expenses) which, by the terms of the Master Lease, become due and payable by Sublessor to Landlord as Additional Rent under the Master Lease or otherwise and which would not have become due and
payable but for the acts, requests for services, and/or failures to act of Sublessee, its agents, officers, representatives, employees, servants, contractors, invitees, licensees or visitors under this Sublease, including but not limited to, any
increases in Landlord’s fire, rent or other insurance premium, as provided in the Master Lease, resulting from any act or omission of Sublessee and not of Sublessor. 
  
 9.2    After receipt by Sublessor of any statement or written demand from Landlord which includes demand
for payment of any amounts payable hereunder as Tenant Surcharges, Sublessor shall deliver to Sublessee a copy of such statement or demand, together with Sublessor’s statement of the amount of such Tenant Surcharges. Sublessee shall pay to
Sublessor the amount of such Tenant Surcharges within ten (10) days (or such shorter period of time as may be required of Sublessor by the terms of the Master Lease) after Sublessee’s receipt of such statement or demand; provided, however, that
in any instance in which Sublessee shall receive any such statement or demand directly from Landlord, provided Sublessee delivers a copy of such statement or demand to Sublessor as soon as reasonably practicable after such receipt, Sublessee may pay
the amount of the same directly to Landlord. Sublessor agrees that if Sublessee pays the amount due directly to lessor, in accordance with the preceding sentence, any obligation of Sublessee to pay the same to Sublessor shall be satisfied by the
payment to Landlord. The amount of Tenant Surcharges payable hereunder by Sublessee shall at all times be equal to the amounts payable by Sublessor under the Master Lease which would not have become due and payable but for the acts, requests for
services, and/or failures to act of Sublessee, its agents, officers, representatives, employees, servants, contractors, invitees, licensees or visitors, as provided in Paragraph 9.1 above. 
  
 9.3    INTENTIONALLY OMITTED. 
  
 9.4    Payments shall be made pursuant to this Section 9
notwithstanding the fact that the statement to be provided by Sublessor is furnished to Sublessee after the expiration of the term of this Sublease and notwithstanding the fact that by its terms this Sublease shall have expired or have been canceled
or terminated. 
  
 9.5    In the event
Sublessor receives notice from Landlord of a change in Additional Rent, Sublessor, within a reasonable time after the receipt by Sublessor of any projected Additional Rent statement from Landlord or any change in the Additional Rent, will furnish
Sublessee with a copy of such statement and copies of any additional materials relating to the Subleased Premises and received by Sublessor in connection with such charge. Upon submission of such statement, all subsequent installments of Additional
Rent hereunder shall include 1/12th of the annual amount of the Additional Rent as shown on such statement; provided, however, that, to the same extent that Sublessor shall be 
  

 7 









 required to pay Landlord any retroactive or other lump sum payments with respect to any such Additional Rent for a period
which is in part prior to the Commencement Date, Sublessee shall pay only that portion thereof which shall be attributable to the period occurring on or after the Commencement Date. 
  
 9.6    If Sublessor shall receive from Landlord any refund of any amounts for which Sublessee shall have
paid Additional Rent to Sublessor or Landlord under the provisions of this Section 9, Sublessor shall retain out of such refund the costs and expenses, if any, of obtaining such refund, including but not limited to reasonable attorney’s fees
and expenses, and shall then pay to Sublessee, within ten (10) days of receipt of such refund by Sublessor, the pro rata portion of the remainder of such refund which is equitably attributable to amounts paid by Sublessee as Additional Rent
hereunder. 
  
 9.7    Notwithstanding anything
herein to the contrary, Sublessee agrees it shall indemnify, defend and hold Sublessor harmless against all costs, claims, loss or liability resulting from delay by Sublessee in surrendering the Subleased Premises upon conclusion of the Term,
including, without limitation, any claims made by any succeeding tenant founded on such delay. The parties recognize and agree that the damage to Sublessor resulting from any failure by Sublessee timely to surrender the Subleased Premises upon the
conclusion of the Term will be substantial, will exceed the amount of monthly rent theretofore payable hereunder, and will be impossible of accurate measurement. Sublessee therefore agrees that if possession of the Subleased Premises is not
surrendered to Sublessor on the conclusion of the Term, then Sublessee will pay Sublessor as liquidated damages for each day during which Sublessee holds over in the Subleased Premises after conclusion of the Term, a sum equal to a per diem amount
equal to 1/30 of one hundred fifty percent (150%) of the average Rent and Additional Rent which was payable by Sublessor under the Master Lease during the last six months of the term hereof for the entire Leased Premises. Any such holding over
without the prior written consent of Sublessor shall create a day-to-day tenancy at sufferance relationship with Sublessee. Sublessee hereby represents, warrants and covenants to Sublessor that Sublessee shall indemnify, defend and hold harmless
Sublessor from and against any and all damages, liabilities, obligations, and expenses (including without limitation legal costs and attorneys’ fees) incurred by Sublessor as a result of Sublessee’s failure to surrender the Subleased
Premises to Sublessor at the conclusion of the Term. Notwithstanding anything herein to the contrary, this Section 9.7 shall survive the conclusion of the Term and this Sublease. 
  
 9.8    If Sublessee shall fail to pay all or any part of any installment of Rent or Additional Rent
within five (5) days from when the same is due and payable, Sublessee shall pay as Additional Rent hereunder to Sublessor a late charge in an amount equal to five percent (5%) of the delinquent payment at the time the delinquent payment is made. The
late charge payable pursuant hereto shall be payable without prejudice to any of Sublessor’s rights and remedies hereunder at law or in equity for nonpayment or late payment of rent or other sum and in addition to any such rights and remedies.
No failure 
  

 8 









 by Sublessor to insist upon the strict performance by Sublessee of Sublessee’s obligations to pay late charges as
provided herein shall constitute a waiver by Sublessor of its right to enforce the provisions hereof in any instance thereafter occurring. The provisions of this paragraph shall not be construed in any way to extend the grace periods or notice
periods provided for elsewhere in this Sublease. 
  
 9.9    The provisions of this Section 9 shall survive the expiration or any earlier cancellation or termination of this Sublease. 
  

 9 









 10.    OTHER PROVISIONS OF SUBLEASE 
  
 10.1    In connection with the incorporation of the
Master Lease as provided in Section 1, the term “Desta Two Partnership, Ltd.” or Landlord, with respect to those provisions which, by their terms, reside exclusively with Landlord (including, but not limited to, the provision of services
and the promulgation of Building-wide rules and standards), shall be deemed to mean “Landlord”, and in all other events shall be deemed, for the purposes of this Sublease, to mean “Sublessor shall use its best efforts, without,
however, incurring any liabilities or expenses not otherwise provided for in the Master Lease or this Sublease, to ensure that Landlord” whenever such a modification is required so that an incorporated provision reflects the agreement of the
parties hereto as expressed in this Sublease. Landlord hereby agrees that in the event that Sublessor is more than five (5) days late in the payment of any installment of Rent or Additional Rent, or in the event that Sublessor is in any other
default of the Master Lease, or upon notice of bankruptcy of Sublessor, Landlord will promptly provide Sublessee with written notice of any such late payment, default or notice of bankruptcy. 
  
 Sublessee assumes and agrees to perform the Sublessor’s obligations
under the Master Lease, exclusive only of the Excluded Provisions, during the Term, except that the obligation to pay rent to Landlord under the Master Lease shall be considered performed by Sublessee to the extent and in the amount rent is paid to
Sublessor in accordance with Section 5 of this Sublease. Sublessee shall not commit or suffer any act or omission that will violate any of the provisions of the Master Lease. Sublessor shall exercise due diligence in attempting to cause Landlord to
perform its obligations under the Master Lease for the benefit of Sublessee. Except as may otherwise be specifically provided herein, if the Master Lease terminates, this Sublease shall terminate and the parties shall be relieved of any further
liability or obligation under this Sublease. Notwithstanding the foregoing, if the Master Lease gives Sublessor any right to terminate the Master Lease in the event of the partial or total damage, destruction, or condemnation of the Subleased
Premises or the Building or project of which the Subleased Premises are a part or otherwise, the exercise of such right by Sublessor shall not constitute a default or breach hereunder, and Sublessee agrees that Sublessor shall be free to exercise
any such rights as may be available to Sublessor without first obtaining any approval from, or consulting with, Sublessee. Landlord agrees that in (i) the event of bankruptcy by the Sublessor in which the Bankruptcy Trustee or Court rejects the
Master Lease; (ii) the event of a default under the Master Lease by Sublessor resulting in a termination of the Master Lease by Landlord; or (iii) the event Sublessee exercises the renewal option under the Master Lease as described in Paragraph 19
hereof, then in such event, Landlord agrees to enter into a Lease Agreement with Sublessee under the same terms and conditions contained in the Sublease provided, at such time, the Sublessee meets the conditions set forth in that certain letter from
Landlord to Sublessee, dated of even date herewith. A copy of such letter is attached hereto as Exhibit “C” and made a part hereof for all purposes as if the text of the letter, exclusive of the Lender Memorandum (hereinafter
defined) attached thereto, were fully set forth herein. 
  

 10 









 10.2    Sublessee shall indemnify, defend, and hold harmless Sublessor from and
against all costs, expenses (including reasonable attorneys’ fees), fines, suits, claims, demands, liabilities and actions resulting from any breach, violation or nonperformance of any covenant or condition hereof or from the use or occupancy
of the Subleased Premises by Sublessee or Sublessee’s employees, agents, contractors, licensees and invitees. 
  
 10.3    Sublessor shall not be liable to Sublessee or Sublessee’s employees, agents, contractors, licensees or invitees for any
damage to person or property resulting from any act or omission of any visitor to the Subleased Premises except as Sublessor’s own negligence may contribute thereto. 
  
 10.4    Provided Sublessee has performed all of the terms, covenants, agreements and conditions of this
Sublease, including the payment of rental and all other sums due hereunder, Sublessee shall peaceably and quietly hold and enjoy the Subleased Premises against Sublessor and all persons claiming by, through or under Sublessor, for the Term herein
described, subject to the provisions and conditions of this Sublease and the Master Lease. 
  
 10.5    No amendment, modification or alteration of the terms hereof shall be binding unless the same shall be in writing, dated subsequent to the date hereof and duly executed by the parties.

  
 10.6    Descriptive headings are for
convenience only and shall not control or affect the meaning or construction of any provision of this Sublease. Whenever the context of this Sublease requires, words used in the singular shall be construed to include the plural and vice versa and
pronouns of whatsoever gender shall be deemed to include and designate the masculine, feminine or neuter gender. 
  
 10.7    For the convenience of the parties, any number of counterparts of this Sublease may be executed by one or more parties hereto
and each such executed counterpart shall be, and shall be deemed to be, an original instrument. 
  
 10.8    This Sublease shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns
in accordance with the terms of this Sublease. 
  
 10.9    Time is of the essence in the performance by Sublessee of its obligations hereunder. 
  
 10.10    Sublessee shall have no right, and Sublessee hereby waives and relinquishes all rights which Sublessee might otherwise have,
to claim any nature of lien against the Building or to withhold, deduct from or offset against any rent or other sums to be paid to Sublessor by Sublessee, except as expressly provided under this Sublease. 
  

 11 









 10.11    Sublessor shall have all rights and remedies against Sublessee as Landlord
has against Tenant in the Master Lease. All rights and remedies of Sublessor hereunder shall be cumulative and none shall exclude any other rights or remedies allowed by law; and this Sublease is declared to be a Texas contract, performable in
Travis County, Texas, and all of the terms hereof shall be construed according the laws of the State of Texas. 
  
 10.12    The terms and provisions of all Schedules and Exhibits described herein and attached hereto are hereby made a part hereof for
all purposes. This Sublease constitutes the entire agreement of the parties with respect to the subject matter hereof, and all prior correspondence, memoranda, agreements or understandings (written or oral) with respect hereto are merged into and
superseded by this Sublease. 
  
 10.13    If
any terms or provision of this Sublease, or the application thereof to any person or circumstance, shall to any extent be invalid or unenforceable, the remainder of this Sublease, or the application of such provision to persons or circumstances
other than those as to which it is invalid or unenforceable, shall not be affected thereby, and each provision of this Sublease shall be valid and shall be enforceable to the extent permitted by law. 
  
 10.14    This Sublease shall not be recorded without the
prior written consent of Sublessor. 
  
 10.15    In the event Sublessee defaults under any provision of this Sublease, Sublessee shall, within ten (10) days after Sublessor’s written request therefor (which written request shall be sent to Sublessee
within thirty (30) days after Sublessor obtains actual knowledge of the default), deliver to Sublessor the Sublessee’s latest annual audited financial statements (which shall be for the year ending within 12 months prior to the date of the
request) and the most recent unaudited quarterly financial statements. Sublessor and Landlord will agree to keep the information contained therein confidential and will not make any disclosure thereof except to a prospective purchaser of the
Building or a prospective mortgagee of same, or as required by law. 
  
 10.16    In case of any breach hereof by Sublessee, in addition to all other rights of Sublessor hereunder or available to Sublessor at law or in equity, Sublessor shall have all rights against Sublessee as would be
available to the Landlord under the Master Lease if such breach were by Sublessor thereunder. In the event Sublessee defaults in the performance of any of the terms and provisions hereof and Sublessor places the enforcement of this Sublease in the
hands of an attorney, Sublessee agrees to reimburse Sublessor for all reasonable expenses incurred by Sublessor as a result thereof, including, but not limited to, reasonable attorneys’ fees. 
  
 10.17    Sublessee acknowledges that, by the Commencement
Date, Sublessor will have terminated any and all utility and service contracts pertaining to Sublessor’s 

  

 12 









 
occupancy of the Subleased Premises, and Sublessee shall be solely responsible for obtaining any similar utility and/or service contracts pertaining to
Sublessee’s occupancy of the Subleased Premises. 
  
 10.18    Notwithstanding anything in this Sublease or in the Master Lease to the contrary, Sublessee shall cooperate as may be necessary to provide estoppel certificates pertaining to the Subleased Premises as the same
may be requested of Sublessee by Landlord or Sublessor. 
  
 10.19     Sublessee shall have the right to use any of Sublessor’s existing wiring, data and telephone cabling present in the Subleased Premises on the Commencement Date. 
  
 11.    BROKER 
  
 11.1    Sublessee warrants and represents to Sublessor
that Office Leasing Advisors, License No. 0435913 (“Sublessee’s Broker”) is the only broker with whom Sublessee has dealt in connection with this Sublease transaction. Sublessor agrees to pay Sublessee’s Broker a commission which
shall equal 4% of the sum of the total net Rent payable throughout the entire Term plus deemed Operating Expenses for the Term. Only for the purposes of calculating the commission in the preceding sentence, the Operating Expenses shall be deemed to
be $10.50 per square foot without right of increase or reduction, which the parties hereby agree represents the estimated Operating Expenses for the year 2001. Sublessor warrants and represents to Sublessee that the Collier’s Oxford Commercial
(“Sublessor’s Broker”) is the only broker with whom Sublessor has dealt in connection with this Sublease transaction. Sublessor shall pay Sublessor’s Broker a commission which shall equal 2% of the sum of the total net Rent
payable throughout the entire Term plus deemed Operating Expenses for the Term. Only for the purposes of calculating the commission in the preceding sentence, the Operating Expenses shall be deemed to be $10.50 per square foot without right of
increase or reduction, which the parties hereby agree represents the estimated Operating Expenses for the year 2001. Sublessee agrees to indemnify, defend and hold harmless Sublessor from and against any and all loss, damage, cost and expense,
including reasonable attorneys’ fees and expenses, that may be incurred by Sublessor as a result of any claims made against Sublessor by any broker or agent, other than the Sublessee’s Broker, arising from any conversation, correspondence,
or the other dealings between Sublessee and any other broker or agent in connection with this Sublease or the Subleased Premises. 
  
 All commission due pursuant to this Section 11 shall be payable as follows: (i) one-half of the commission shall be paid by Sublessor to each Broker upon
execution of this Sublease; and (ii) commencing January 1, 2002, the remaining one-half of the commission shall be paid by Sublessee directly to each Broker with a copy to Sublessor in lieu of payment of the Rent (exclusive of Additional Rent) on a
monthly basis until the Sublessor’s Broker and the Sublessee’s Broker are paid in full (which computes to four (4) full months’ Rent and a portion of Rent for the fifth (5th) month of the Sublease). Failure of Sublessee 
  

 13 









 to deliver notice of payment of the commissions each month in accordance with Section 11.1(ii) shall be an event of
default of this Sublease. In the event Sublessee fails to pay the commissions to Sublessee’s Broker and to Sublessor’s Broker as provided herein, then Sublessor shall be relieved of any liability for Sublessee’s failure to pay such
commissions, Sublessee’s Broker and Sublessor’s Broker shall have no recourse against Sublessor for such unpaid commissions, and Sublessee shall indemnify, defend, and hold harmless Sublessor from and against any claim, suit, or demand by
Sublessee’s Broker and/or Sublessor’s Broker for such unpaid commissions. 
  
 12.    ATTORNEYS’ FEES 
  
 12.1    If Sublessor or Sublessee shall commence an action against the other arising out of or in connection with this Sublease, the prevailing party shall be entitled to recover its costs of suit and reasonable

 13.1    All notices, consents, requests, instructions, approvals and other communications provided for herein and all legal process in regard hereto shall only be validly given, made or served if in writing and delivered

Landlord gives its consent or approval (as the case may be) to such act, Sublessor shall (except as otherwise specifically set out in this Sublease to the contrary) not unreasonably withhold its consent to such act. Sublessee expressly waives any
rights to monetary damages or other remedies other than the right to seek injunctive relief in cases agrees where Sublessor’s reasonableness in withholding or delaying its consent or approval under applicable provisions of this Sublease is
challenged by Sublessee.
