                b.

              	
                Second
      and Succeeding Annual Periods:  To provide an equitable
      adjustment of rental to allow for increases in operating expenses incurred
      through the operation of the Building, the rental shall be adjusted in
      accordance with the following
procedures:

              


      

      


      The
Landlord shall prepare annually prior to the end of each calendar year an
estimate of total operating expenses for the upcoming calendar
year.

      


      Commencing
    June
1st,
2009               Tenant
shall pay monthly additional rental consisting of one twelfth (1/12) of the
difference between the "Base Year" actual operating expense costs and the
upcoming year's estimated operating expense costs allocated to the Leased
Premises.  For purposes of this Lease Agreement the "Base Year” shall
be the calendar year of     2008     .  This
additional rent allocation shall be based on the proportion of the Leased
Premises' net rentable area to the Building's total net rentable
area.  Tenant's proportionate share for purposes defined herein shall
be    7.3898 % of the total
estimated operating expense increase.

      


      After the
first annual period (first lease year), Landlord may from time to time
throughout the calendar year adjust the amount Tenant pays to Landlord monthly
for increases or
decreases in operating expenses, should Landlord reasonably determine
that the actual costs for operating expenses are significantly above or below
the estimated costs for operating expenses.

      


      In no
event shall Landlord include costs for capital replacement items, capital
expenditures, leasing commissions, or any expenditure that would be capitalized
in accordance with generally accepted accounting principles in the actual or
estimated operating expense calculations.

      


      Within
ninety (90) days after the conclusion of each calendar year of the Lease Term,
or as soon thereafter as possible, Landlord shall provide Tenant a detailed
statement of actual operating expenses for the previous calendar
year.  The actual operating expenses shall be compared to the
estimated operating expenses, and Tenant's account shall be adjusted annually upon completion
of audited financials by an increase or decrease based on Tenant's
proportionate share, to reflect actual cost incurred.  The Tenant
shall then be credited or billed accordingly to reflect this
adjustment.  The operating expense adjustment shall in no event cause
the initial base rent to decrease.

        
          
             


          

          
            
              

            

          

          
             


          

        



      


      For
purposes of calculating Tenant's initial  escalation amount, Landlord
shall estimate the   2009 calendar year's
operating expenses prior toJune, 2009 and
compare the estimated amount to the actual operating expenses incurred in
calendar year   2008 .  Tenant
shall commence paying the prorated calendar year difference between the amounts
in monthly increments beginning June,
2009.

      


      During
the last year of the term of this Lease Agreement, Tenant's share of increases
in operating expenses shall be calculated on a proportionate basis so Tenant is
charged only for increases in operating expenses applicable to those months
which this Lease Agreement is in effect.

      


      All sums
or amounts which Tenant shall be or become obligated to pay under this Lease
shall be deemed Rent, whether referred to as "Rental or Rent or Additional Rent"
or otherwise, and Landlord shall have all of the remedies provided by Law for
the collection thereof.  Additionally, Tenant's obligation to pay its
share of actual costs found to be excess of estimated costs shall survive any
termination of this Lease, whether by lapse of time or otherwise.

      


      
        	
                 
      

              	
                c.

              	
                Past
      Due Rent:  Any installments of rent not received by Landlord by
      the fifth day of each month, shall be assessed a late charge equal to 10%
      of the total rental amount due.  Rental payments not received by
      the last day of any given month shall be assessed an additional 10% late
      charge on the total delinquent balance.  It is agreed that the
      late payment charge shall constitute liquidated damages to reimburse
      Landlord for the damages to Landlord in connection with the handling and
      processing of late rent
installments.

      Section 21.  Entry
by Landlord

      


      Tenant
covenants and agrees upon receipt of reasonable notice from Landlord to permit
Landlord or its agents or representatives to enter into and upon any part of the
Leased Premises during normal business hours, unless otherwise agreed with
Tenant, with prospective purchasers, prospective tenants of the Building,
mortgagees, or insurers, to clean or make repairs, alterations, or additions
thereto, as Landlord may deem necessary or desirable, and Tenant shall not be
entitled to any abatement or reduction of rent by reasons
thereof.

      Section
22.  Assignment and Subletting

      


      (I)           Tenant
shall not, without the prior written consent of Landlord, (A) assign or in any
manner transfer this Lease or any estate or interest therein, or (B) permit any
assignment or transfer of this Lease, or (C) sublease the Leased Premises or any
part thereof, or (D) grant any license, concession, or other right of occupancy
of any portion of the Leased Premises.  Consent by Landlord to one or
more assignments or sublettings shall not operate as a waiver of Landlord's
right as to any subsequent assignments and
sublettings.  Notwithstanding any approved assignment or subletting,
Tenant shall at all times remain fully responsible and liable for the payment of
the rent herein specified and for compliance with all of Tenant's other
obligations under this Lease and in the event of any assignment, by operation of
law, merger, consolidation or otherwise, any assignee shall assume and agree to
perform all obligations of Tenant hereunder.  If an event of default,
as hereinafter defined, should occur while the Leased Premises or any part
thereof are then assigned or sublet, Landlord, in addition to any other remedies
herein provided or provided by law, may at its option, collect directly from
such assignee or sub-tenant, and apply such rent against any sums due to
Landlord by Tenant hereunder and Tenant hereby authorized any such assignee or
sub-tenant to make such payments of rent directly to Landlord upon receipt of
notice from Landlord.  No direct collection by Landlord from any such
assignee or sub-tenant shall be construed to constitute a novation or a release
of Tenant from the further performance of its obligations
hereunder.  Receipt by Landlord of rent from any assignee, sub-tenant,
or occupant of the Leased Premises shall not be deemed a waiver of the covenant
contained in this Lease against assignment and subletting or a release of Tenant
under this Lease.  Tenant shall not mortgage, pledge, or otherwise
encumber its interest in this Lease or in the Leased Premises.  Any
attempted assignment or sublease by Tenant in violation of the terms and
covenants of this paragraph shall be void.  If Tenant is a
corporation, partnership or other entity and if at any time during the primary
term of this Lease or any renewal or extension thereof the person or persons who
own a majority of either the outstanding voting rights or the outstanding
ownership interests of Tenant at the time of the execution of this Lease cease
to own a majority of such voting rights of ownership interests (except as a
result of transferees by rights or ownership interests), such shall be deemed an
assignment of this Lease by Tenant and, therefore, subject in all respects to
the provisions of this Section 22. (I).  The previous sentence shall
not apply however, if at the time of the execution of this Lease, Tenant is a
corporation and the outstanding voting shares of capital stock of Tenant are
listed on a recognized security exchange or over the counter
market.

      


      (II)           In
the event Tenant desires Landlord's consent to an assignment of the Leases or
subletting of all or a part of the Leased Premises and as a condition to the
granting of such consent, Tenant shall submit to Landlord in writing the name of
the proposed assignee or sub-tenant, the proposed commencement date of such
assignment or subletting, the nature and character of the business of the
assignee or sub-tenant and such financial information as shall be reasonably
necessary for Landlord to determine the credit worthiness of such proposed
assignee or sub-tenant, Landlord shall have the option (to be exercised within
thirty (30) days from submission of Tenant's written request), (A) to refuse to
consent to Tenant's assignment or subleasing of such space and to compel Tenant
to continue this Lease in full force and effect as to the entire Leased
Premises; or (B) to permit Tenant to assign or sublet such space; subject,
however, to provisions satisfactory to Landlord for payment to Landlord of any
consideration to be paid by such proposed assignee or sub-tenant in connection
with such assignment or subletting in excess of Base Rental otherwise payable by
Tenant and for payment to Landlord of any lump sum payment in connection with
such assignment or subletting.  If Landlord should fail to notify
Tenant in writing of its election as described above within such thirty (30) day
period, Landlord shall be deemed to have elected option (B) above.

      


      Section
23.  Transfers of Landlord

      


      Landlord
shall have the right to transfer and assign, in whole or in part, all its rights
and obligations hereunder and in the Building and property referred to herein,
and provided Landlord's transferee assumes the duties and obligations of
Landlord arising from and after the date of any such transfer or assignment,
upon such transfer or assignment Landlord shall be released from any further
obligations hereunder, and Tenant agrees to look solely to such
successor-in-interest of Landlord for the performance of such
obligations.  Landlord shall advise Tenant in writing of its assignee
and all requisite contact names, addresses and phone numbers prior to the
effective date of assignment.  Notwithstanding the above, no such
assignment will relieve Landlord of any obligation to the Lease existing prior
to such assignment and/or transfer.

      


      


      Section
24.  Subordination to Mortgage

      


      This
Lease shall be subject and subordinate to any mortgage or deed of trust which
may hereafter encumber the Building, and to all renewals, modifications,
consolidations, replacements, and extensions thereof, which contain (or which
are included in a separate agreement) provisions to the effect that if there
should be a foreclosure or sale under power under such mortgage or deed of
trust, Tenant shall not be made a party defendant thereto, nor shall such
foreclosure or sale under power disturb Tenant's possession under this Lease,
provided always Tenant shall not be in default under this Lease.  This
clause shall be self-operative and no further instrument of subordination need
be required by any mortgagee.  In confirmation of such subordination,
however, Tenant shall at Landlord's request, execute promptly any certificate or
instrument evidencing such subordination that Landlord may reasonably
request.

      Tenant
hereby constitutes and appoints Landlord the Tenant's attorney-in-fact to
execute any such certificate or instrument for and on behalf of
Tenant.  In the event of the enforcement by the trustee or the
beneficiary under any such mortgage or deed of trust of the remedies provided
for by law or by such mortgage or deed of trust, Tenant will, upon request of
any person or party succeeding to the interest of Landlord as a result of such
enforcement, automatically become the Tenant of such successor-in-interest
without change in the terms of other provisions of this Lease; provided,
however, that such successor in interest shall not be bound by any amendment or
modification of this Lease made without the written consent of such trustee or
such beneficiary or such successor in interest.  Upon request by such
successor-in-interest, Tenant shall execute and deliver an instrument or
instruments confirming the attornment provided for herein.

      


      Section
25.  Mechanics Liens

      


      Tenant
will not permit any mechanic's lien or liens to be placed upon the Leased
Premises or improvements thereon or the Building during the term hereof caused
by or resulting from any work performed, materials furnished, or obligation
incurred by or at the request of Tenant, and nothing contained in this Lease
shall be deemed or construed in any way as constituting the consent or request
of Landlord, express or implied, by inference or otherwise, to any contractor,
sub-contractor, laborer, or materialman for performance of any labor or the
furnishing of any materials for specific improvement, alteration, or repair of
or to the Leased Premises, or any part thereof, nor as giving Tenant any right,
power, or authority to contract for or permit the rendering of any services or
the furnishing of any materials that would give rise to the filing of any
mechanic's or other liens against the interest of Landlord in the Leased
Premises. In the case of the filing of any lien on the interest of Landlord or
Tenant in the Leased Premises, Tenant shall cause the same to be discharged of
record within ten (10) days after the filing of same by procuring the discharge
of such lien.  If Tenant shall fail to discharge such mechanic's lien
within such period, then, in addition to any other right or remedy of Landlord,
Landlord may, but shall not be obligated to, discharge the same, either by
paying the amount claimed to be due, or by procuring the discharge of such lien
by deposit in court or bonding.  Any amount paid by Landlord shall be
repaid by Tenant to Landlord on demand, including interest thereon at the rate
of ten per cent (10%) per annum or the highest lawful rate, whichever is the
less.

      


      Section
26.  Estoppel Certificates

      


      Tenant
will, from time to time, upon not less than ten (10) days prior request by
Landlord, and at Landlord's reasonable request, execute, acknowledge, and
deliver to Landlord a statement in writing executed by Tenant certifying that
Tenant is in possession of the Leased Premises under the terms of the Lease,
that this Lease is unmodified and in full effect (or, if there have been
modifications, that this Lease is in full effect as modified, and setting forth
such modifications), and that as of such date the rent has been paid, and either
stating that to the knowledge of Tenant no default exists hereunder, or
specifying each such default of which Tenant may have knowledge, and such other
matters as may be reasonably requested by Landlord; it being intended that any
such statement by Tenant may be relied upon by any prospective purchaser or
mortgagee of the Building.

      


      Section
27.  Events of Default

      


      (I)           The
following events shall be deemed to be "Events of Default" by Tenant under this
Lease:

      (A)  Failure
to pay any installment of the Base Rental or other sums of money payable
hereunder when due and continuance of such failure for fifteen (15)
days';

      (B)  Failure
to comply with any term, provision, or covenant of this Lease, other than the
payment of rent, and not curing such failure within a ten (10) day grace period
after written notice thereof to Tenant, or, if such failure cannot reasonably be
cured within such ten (10) day period, Tenant shall commence such actions as are
necessary to cure such defect within such ten (10) day period and thereafter
diligently prosecute such curative action.

      (C)  Tenant
shall become insolvent, or shall make a transfer in fraud of creditors, or shall
commit any act of bankruptcy, or shall make an assignment for the benefit of
creditors or admission in writing of its inability to pay its debts as they
become due.

      (D)  Tenant
shall file a petition with any bankruptcy court under any section or chapter of
the United States Bankruptcy Code, as amended, or under any similar law or
statute of the United States Bankruptcy Code, as amended, or under any similar
law or statute, or Tenant shall have filed any petition or answer seeking any
reorganization, arrangement, composition, readjustment, liquidation,
dissolution, or similar relief under any present or future federal or state act
or law relating to bankruptcy, insolvency or other relief of debtors, or Tenant
shall be the subject of any order, judgement or decree entered into by a court
of competent jurisdiction approving a petition filed against Tenant for any
reorganization, arrangement, composition, readjustment, liquidation, dissolution
or similar relief under any present or future federal or state act relating to
bankruptcy, insolvency or other relief for debtors.

      (E) A
receiver, conservator or trustee shall be appointed for all or substantially all
of the assets of Tenant or of the Leased Premises or any of Tenant's property
located thereon in any proceeding brought by Tenant, or any such receiver or
trustee shall be appointed in any proceeding brought against Tenant and shall
not be discharged within sixty (60) days after such appointment, or tenant shall
consent or acquiesce in such appointment.

      (F) The
Leased Premises hereunder shall be taken on execution or other process of law in
any action against Tenant.

      (II)           If
an Event of Default shall have occurred, Landlord shall have the right at its
election, then or at any time thereafter (and upon the expiration of any
applicable grace period, Tenant shall not be entitled to cure same and be
reinstated as "Tenant" in good standing hereunder), to pursue any one or more of
the following remedies in addition to all other rights or remedies provided
herein or at law or in equity:

      (A)
Landlord may terminate this Lease and forthwith repossess the Leased Premises
and shall be entitled to recover forthwith as damages a sum of money equal to
the total of (1) the cost of recovering the Premises, (2) the unpaid rent earned
at the time of termination, plus interest thereon at the rate of ten percent
(10%) per annum or the maximum legal rate, whichever is lesser, from the due
date, (3) the balance of the rent for the remainder of the term less the fair
market value of the Leased Premises for such period, and (4) any other sum of
money and damages owed by Tenant to Landlord in accordance
herewith.

      (B)
Landlord may terminate Tenant's right of possession (but not the Lease) and may
repossess the Leased Premises by legal means or detainer suit, without demand or
notice of any kind to Tenant and without terminating this Lease, in which event
Landlord may, but shall be under no obligation to do so, relet the same for the
account of Tenant for such rent and upon such terms as shall be satisfactory to
Landlord.  For the purpose of such reletting, Landlord is authorized
to decorate or to make any reasonable repairs, changes, alterations, or
additions in or to the Leased Premises and to incur leasing commissions that may
be necessary or convenient and reasonable, and (1) if Landlord shall fail or
refuse to relet the Leased Premises or (2) if the same are relet and a sum equal
to the rent that would have otherwise been paid by Tenant over time, discounted
to obtain present value shall not be realized from such reletting after paying
the unpaid Base Rental Amount and Additional Rent due hereunder earned, but
unpaid at the time of reletting, plus ten percent (10%) interest thereon or the
highest lawful rate, whichever is lesser, the cost of recovering possession, and
all of the reasonable costs and expenses of such decorations, repairs, changes,
alterations and additions, and leasing commissions and the expense of such
reletting and of the collection of the rent accruing therefrom to satisfy the
rent provided for in this Lease to be paid, then Tenant shall pay to Landlord as
damages a sum equal to the amount of the rent reserved in this Lease for such
period or periods, or if the Leased Premises have been relet Tenant shall
satisfy and pay any such deficiency upon demand therefor from time to time, and
Tenant agrees that Landlord may file suit to recover any sums falling due under
the terms of this Section 27 from time to time; and that no delivery or recovery
of any portion due Landlord hereunder shall be any defense in any time; and that
no delivery or recovery of any portion due Landlord hereunder shall be any
defense in any action to recover any amount not theretofore reduced to judgement
in favor of Landlord, nor shall such reletting be construed as an election on
the part of Landlord to terminate this Lease unless a written notice of such
intention be given to Tenant by Landlord.  Notwithstanding any such
reletting without termination, Landlord may at any time thereafter elect to
terminate this Lease for such previous breach.

      


      Section
28.  Landlord's Right to Relet

      


      In the
event of default by Tenant in any of the terms or covenants of this Lease or in
the event the Leased Premises are abandoned by Tenant, Landlord shall have the
right, but not the obligation to relet same for the remainder of the term
provided for herein, and if the rent received through reletting does not at
least equal the rent that would have otherwise been paid by Tenant over time,
discounted to obtain present value, Tenant shall pay and satisfy the deficiency
between the amount of the rent so provided for and that received through
reletting, including, but not limited to, the reasonable cost of renovating,
altering and decorating for a new occupant as well as any reasonable leasing
commissions incurred in connection therewith.  Nothing herein shall be
construed as in any way denying Landlord the right, in the event of abandonment
of the Leased Premises or other breach of this Lease by Tenant, to treat the
same as an entire breach of this Lease and any and all damages which Landlord
suffers thereby.

      


      Section 29.  Lien
for Rent

      


      None.

      


      Section
30.  Attorney's Fees

      


      If on
account of any breach or default by Tenant in its obligations hereunder,
Landlord shall employ an attorney to present, enforce or defend any of
Landlord's rights or remedies hereunder, Tenant agrees to pay any reasonable
attorney's fees incurred by Landlord in such connection.

      


      


      Section 31.  No
Implied Waiver

      


      The
failure of Landlord to insist at any time upon the strict performance of any
covenant or agreement or to exercise any option, right, power, or remedy
contained in this Lease shall not be construed as a waiver or a relinquishment
thereof for the future.  The waiver of or redress for any violation of
any term, covenant, agreement, or condition contained in the Lease shall not
prevent a subsequent act, which would have originally constituted a violation,
from having all the force and effect of an original
violation.   No express waiver shall affect any condition other
than the one specified in such waiver and that one only for the time and in the
manner specifically stated.  A receipt by Landlord of any rent with
knowledge of the breach of any covenant or agreement contained in this Lease
shall not be deemed a waiver of such breach, and no waiver by Landlord of any
provision of this Lease shall be deemed to have been made unless expressed in
writing and signed by Landlord.

       No
payment by Tenant or receipt by Landlord of a lesser amount than the monthly
installment of rent due under this Lease shall be deemed to be other than on
account of the earliest rent due hereunder, nor shall any endorsement or
statement on any check or any letter accompanying any check or payment as rent
be deemed an accord and satisfaction, and Landlord may accept such check or
payment without prejudice to Landlord's right to recover the balance of such
rent or pursue any other remedy in this Lease provided.

      


      Section
32.  Insurance

      


      PROPERTY:
Landlord shall maintain fire and extended coverage insurance on the
Building.  Such insurance shall be maintained with an insurance
company authorized to do business in Texas, in amounts desired by Landlord and
at the expense of Landlord (as a part of the Operating Expenses), and payments
for losses thereunder shall be made solely to Landlord.   If the
annual premiums to be paid by Landlord shall exceed the standard rates because
Tenant's operations, contents of the Leased Premises, or improvements with
respect to the Leased Premises are beyond building standard, Tenant shall pay
the excess amount of the premium within ten (10) days of receipt of written
request by Landlord.   Tenant acknowledges and agrees that
insurance coverage carried by Landlord will not cover Tenant's property within
the Leased Premises or the Building and that Tenant shall be responsible, at
Tenant's sole cost and expense, for providing insurance coverage for Tenant's
movable equipment, furnishing, trade fixtures and other personal property in or
upon the Leased Premises or the Building, and for any alteration, additions or
improvements to or of the Leased Premises or any part thereof made by Tenant, in
the event of damage or loss thereto from any cause
whatsoever.   Tenant shall procure and maintain throughout the
term of this Lease a policy or policies of insurance, at its sole cost and
expense, insuring Tenant and Landlord against any and all liability for injury
to or death of a person or persons' occasioned by or arising out of or in
connection with the use or occupancy of the Leased Premises, the limits of such
policy or policies to be in an amount not less than $1,000,000 with respect to
injuries to or death of any person and in an amount of not less than $1,000,000
with respect to any one accident or disaster, and shall furnish evidence
satisfactory to Landlord of the maintenance of such insurance.  Tenant
shall obtain a written obligation on the part of such insurance company to
notify Landlord at least 10 days prior to cancellation of such
insurance.  It is recommended that Tenant carry fire and extended
coverage insurance on its personal property, as Landlord shall in no event be
required to rebuild, repair or replace any part of the furniture, equipment,
fixtures and other improvements which may have been placed by Tenant on or
within the Leased Premises.

      


      Section 33.  Legal
Use and Violations of Insurance Coverage

      


      Tenant
covenants and agrees with Landlord not to occupy or use, or permit any portion
of the Leased Premises to be occupied or used, for any business or purpose which
is unlawful, disreputable, or deemed to be extra-hazardous on account of fire,
or permit anything to be done which would in any way increase the rate of fire,
liability, or any other insurance coverage on the Building and/or its
contents.

      


      Section
34.  Indemnity

      


      Each
party to this agreement agrees to indemnify the other for and defend and hold
the other harmless from and against all fines, suits, claims, demands,
liabilities and actions [including reasonable costs and expenses of defending
against such claims) resulting or alleged to result from any breach, violation
or non-performance of any covenant or condition hereof, or from the use or
occupancy of the Leased Premises, by said party or its agents, employees,
licensees, or invitees, for any damage to person or property resulting from any
act or omission or negligence of any co-tenant, visitor or other occupancy of
the Leased Premises except as the party's own negligence may contribute
thereto.

      


      Section
35.  Waiver of Subrogation Rights

      


      Anything
in this Lease to the contrary notwithstanding, Landlord and Tenant each hereby
waives any and all rights of recovery, claim, action, or cause of action,
against the other, its agents, officers, or employees, for any loss or damage
that may occur to the Leased Premises, or any improvements thereto, or any
personal property of such party therein, by reason of fire, the elements, or any
other cause which are insured against under the terms of standard fire and
extended coverage of policies, regardless of cause or origin, including
negligence of the other party hereto, its agents, officers, or employees, and
covenants that no insurer shall hold any right of subrogation against such other
party.

      


      Section
36.  Casualty Damage

      


      If the
Leased Premises or any part thereof shall be damaged by fire or other casualty,
Tenant shall give prompt written notice thereof to Landlord.  In case
the Building shall be damaged by fire or other casualty, but shall not be
rendered untenantable in whole or in part, Landlord shall, at its sole expense,
cause such damage to be repaired with reasonable diligence to substantially the
same condition in which it was immediately prior to the happening of the
casualty, and the Base Rental Amount hereunder shall not be abated; however, in
case the Building shall be so damaged by fire or other casualty that substantial
alteration or reconstruction of the Building shall, in the agreement of Landlord
and Tenant, or if they cannot agree, in the opinion of an independent third
party architect, be required (whether or not the Leased Premises shall have been
damaged by such fire or other casualty), or in the event any mortgagee under a
mortgage or deed of trust covering the Building should require that the
insurance proceeds payable as a result of said fire or other casualty be used to
retire the Mortgage debt,

      Landlord
may, at its option, terminate this Lease and the term and estate hereby granted
by notifying Tenant in writing of such termination within sixty (60) days after
the date of such damage.  If Landlord does not thus elect to terminate
this Lease, Landlord shall within seventy-five (75) days after the date of such
damage commence to repair and restore the Building and shall proceed with
reasonable diligence to restore the Building which restoration shall be
completed no later than 120 days from the date of such damage to substantially
the same condition in which it was immediately prior to the happening of the
casualty, except that Landlord shall not be required to rebuild, repair, or
replace any part of Tenant's fixtures, equipment or other personal property
removable by Tenant under the provisions of this Lease, and Landlord shall not
in any event be required to spend for such work an amount in excess of the
insurance proceeds actually received by Landlord as a result of the fire or
other casualty. Landlord shall not be liable for any inconvenient or annoyance
to Tenant or injury to the business of tenant resulting in any way from such
damage or the repair thereof, except that, subject to the provisions of the next
sentence, Landlord shall allow Tenant a proportionate diminution of rent based
on the percentage of the Leased Premises that is affected during the time and to
the extent the Leased Premises, or any portion thereof, are unfit for occupancy.
If the Premises or any other portion of the Building shall be damaged by fire or
other casualty resulting from the willful
fault or negligence of Tenant or any of Tenant's agents, employees, or invitees
in the Leased Premises, the rent hereunder shall not be diminished during the
repair of such damage, and Tenant shall be liable to Landlord for the cost and
expense of the repair of such damage, and Tenant shall be liable to Landlord for
the cost and expense of the repair and restoration of the Building caused
thereby to the extent such cost and expense is not covered by insurance
proceeds.  Any insurance which may be carried by Landlord or Tenant
against loss or damage to the Building or to the Leased Premises shall be for
the sole benefit of the party carrying such insurance and under its sole
control.

      


      Section
37.  Condemnation

      


      If the
whole or substantially the whole of the Leased Premises should be taken for any
public or quasi-public use under any governmental law, ordinance, or regulation
or by right of eminent domain, or should be sold to the condemning authority in
lieu of condemnation, then this Lease shall terminate as of the date when
physical possession of the Leased Premises is taken by the condemning
authority.  If less than the whole or substantially the whole Building
or the Leased Premises is thus taken or sold, Landlord (whether or not the
Leased Premises are affected thereby) may terminate this Lease by giving written
notice thereof to Tenant immediately
after the right of election accrues, in which event this Lease shall terminate
as of the date when physical possession of such portion of the Building or
Leased Premises is taken by the condemning authority.  If upon any
such taking or sale of less than the whole or substantially less than the whole
of the Building or the Leased Premises, this Lease shall not be thus terminated,
the Base Rental Amount and Additional
Rental payable thereunder shall be diminished by an amount representing
that part of the Base Rental Amount and Additional
Rental as shall be allocable to the portion of the Leased Premises which
was so taken or sold or affected, and Landlord shall, at Landlord's sole
expense, restore and reconstruct the Parking Area, Building or the Leased
Premises, as the case may be, to substantially their former condition to the
extent that the same, in Landlord's judgement, may be feasible; Landlord shall
not in any event be required to spend for such work an amount in excess of the
amount received by Landlord as compensation awarded upon a taking of any part or
all of the Parking Area, Building or the Leased Premises, and Tenant shall not
be entitled to and expressly waives all claim to any such
compensation.

      


      Section
38.  Notices and Cure

      


      In the
event of any act or omission by Landlord which would give Tenant the right to
damages from Landlord or the right to terminate this Lease by reason of the
constructive or actual eviction from all or part of the Leased Premises or
otherwise, Tenant shall not sue for such damages or exercise any such right to
terminate until it shall have given written notice of such act or omission to
Landlord and a reasonable period of time for remedying such act or omission
shall have elapsed following the giving of such notice, during which time
Landlord, their agents or employees, shall be entitled to enter upon the Leased
Premises and do therein whatever may be necessary to remedy such act or
omission.  During the period after the giving of such notice and
during the remedying of such act or omission, the Base Rental Amount and Additional
