  made part of the lease above described to which it is attached and in each
  instance in which the provisions, or any part thereof, of this rider shall
  contradict or be inconsistent with the provisions, or any part thereof, of
  said lease as constituted without this rider, the provisions of this rider

said lease shall be deemed amended accordingly.

38. LIENS

Tenant agrees to indemnify
  and save Landlord harmless from and against any and all bills for labor performed
  or equipment, fixtures and materials furnished to or for Tenant, and from and
  against any and all liens, bills or claims therefore or against the demised
  premises or the building of which it forms a part, and from and against all
  losses, damages, costs, expenses, suits and claims whatsoever in connection
  with the work performed by or for Tenant. The demised premises and the building
  shall at all times be free of liens for labor and materials supplied or claimed
  to have been supplied to or on behalf of Tenant, and no financing statements
  or other security instruments shall be filed against the demised premises or
the building or the contents thereof.

Tenant shall not directly or indirectly create or permit to be created or to remain, and shall discharge, any mortgage, lien, security interest, encumbrance or charge on, pledge of or conditional sale or other retention agreement
with respect to the demised premises or any part thereof, any equipment, fixtures or materials therein, Tenants interest under this lease, or any fixed rent or other rent payable under this lease. Supplementing the provisions of Article
3 hereof, the parties agree that if any action, suit or proceeding be brought upon any lien of the nature described in Article 3 hereof, for the enforcement of foreclosure of the same, Tenant covenants and agrees, at its own
cost and expense, to defend the Landlord herein and to pay any and all costs and damages, including Landlords attorneys fees,
and satisfy and discharge any judgment entered therein.

Further supplementing the provisions of Article 3 hereof, Tenant agrees to deliver to Landlord, not later than five (5) business days prior to the date contemplated for the commencement of any alteration, certificates
of general liability, property damage and public liability insurance in form and content satisfactory to Landlord together with Workers Compensation Insurance certificate, all with evidence of payment of premium thereon and providing for at
least (10) days prior written notice of cancellation of same to Landlord.

39. LATE CHARGE

Whenever in this lease any sum, amount, item or charge, other than reserved rent, shall become due and payable by Tenant to Landlord, the same shall be deemed to be additional rent and the Landlord shall have the same rights and
remedies for the nonpayment thereof as the Landlord would have for the nonpayment of the reserved or minimum rent herein stipulated and provided for to be paid by the Tenant. In the event that any payment to be made by Tenant shall become overdue
for a period in excess of ten (10) days, a late charge of One Hundred Dollars ($100.00) may be charged by Landlord and shall be payable by Tenant on the 1st day of the month following Landlords demand therefor.  The phrase
rent as used in this lease shall mean the fixed or minimum rent reserved
hereunder together with all other charges due from Tenant hereunder, which collectively
constitute additional rent.

40. DEMAND FOR CERTIFIED CHECKS

In the event Tenant
  shall furnish Landlord with four (4) insufficient funds checks during the period
  of this lease term, or each successive option period if applicable, Tenant
  will then be required to furnish Landlord with certified checks for all rent,
  additional rent, and arrears due and owing throughout the term of the lease
  and/or option period. Failure by Tenant to comply with this provision will
constitute a default under the terms hereof.

41. HEATING, VENTILATION, AND AIR CONDITIONING

(a) As long as Tenant is not in default under this lease, the Landlord, at its own cost and expense, shall, through the central air conditioning, heating and ventilation system of the building, furnish and distribute in the
demised premises, ventilation and/or conditioned air (which term includes heating from October 1st through April 30th, as well as air cooling from May 1st to September 30th) on business days (Monday through Friday, holidays excepted) from 8:30 A.M.
to 5:30 P.M. prevailing time, and on Saturdays from 8:30 A.M. to 2:00 P.M. when in Landlords reasonable judgment the same is required for comfortable occupancy of the demised premises. Tenant shall keep and cause to be kept closed the doors
(when not in use) and all of the windows in the demised premises whenever the air conditioning system is in operation, and to lower and close the blinds when reasonably necessary because of the suns
position. Tenant agrees to cooperate fully with Landlord at all times and to
abide by all rules, regulations and requirements which Landlord reasonably may
prescribe for the proper functioning and protection of the HVAC system.

(b) Landlord shall have free and unrestricted access to all HVAC equipment.  Landlord reserves the right to interrupt, curtail, stop or suspend any of the services herein referred when necessary because of accident, repairs,
alterations or improvements, which in the judgment of Landlord are desirable or necessary, or to comply with government restrictions in the use of materials or in the use of the HVAC system or because of strikes or other cause or causes beyond the
reasonable control of the Landlord, whether such other cause or causes are similar or dissimilar to those hereinabove mentioned, and no diminution or abatement of rent or other compensation shall or will be claimed by the Tenant nor shall this lease
or any of the obligations of the Tenant be affected or reduced by reason of the interruptions, curtailment or suspension of HVAC services, provided that if resumption is, or becomes, within Landlords
reasonable control, Landlord shall use all diligent and reasonable efforts to
cause such resumption.

If Tenant shall require any heating, ventilation or air conditioning service after the standard hours, Tenant shall request such service at least twenty-four (24) hours prior to the time Tenant desires said overtime services.
Tenant agrees to pay, as additional rent, such charges for such overtime services as Landlord reasonably may determine from time to time. Landlords
charges for providing such additional service shall be proportionately increased
as increases in electricity or steam rates occur. Landlord shall have the right
to decline to furnish conditioned air on hours and days other than the regular
hours and days if, in the reasonable opinion of the Landlord, the furnishing
of such service would be impractical or detrimental to the operation of the building.

42. TAX ESCALATION

(a) The term Real Property shall
mean collectively the land and the building erected thereon.

2

---



(b) The term Taxes shall
  mean all the taxes and assessments, special or otherwise, levied, assessed
  or imposed by Federal, State or Local Governments against the Real Property
  of which the demised premises form a part. If due to a future change in the
  method of taxation, any franchise, income, profit or other tax, or other payment,
  shall be levied against Landlord in whole or in part in substitution for or
  in lieu of any tax which would otherwise constitute a Tax, such franchise,
  income, profit or other tax or payment shall be deemed to be a Tax for the
purposes hereof.

(c) The term Tax Year shall mean each period of twelve (12) consecutive months commencing on the first day of the Base Tax Year (as defined below), and each twelve month period thereafter, or such other period as may
hereafter be duly adopted as the fiscal year for real estate tax purposes by the City of Englewood Cliffs. As used herein and in Article 43 hereof, the phrase term of the lease shall mean the original term provided for in this lease and
any renewal or extension thereof, irrespective of the sooner termination hereof by reason of Tenants
default.

(d) The term Base Tax Year shall
mean the Calendar Year 2009.

(e) The term Base Taxes shall
mean the Taxes payable for the Base Tax Year.

(f) If taxes for any
  Tax Year shall be increased above the Base Taxes, then the Tenant shall pay
to the Landlord as additional rent 0.68% of
such increase. The amount due hereunder shall be paid by Tenant within ten (10)
days after the Landlord shall submit a  statement to Tenant, showing in reasonable
detail, the computation of the amount, if any, due hereunder to Landlord. Landlord
shall have the right, at its sole discretion, to bill Tenant the amount due hereunder
either in one lump sum or in equal  monthly installments. Any such tax increase
for the Tax Year in which this lease shall end shall be apportioned.

(g) A tax bill for
  any relevant Tax Year (including the Base Tax Year) shall be conclusive evidence
  of the amount of taxes imposed for such year unless the assessment for such
  year be protested and, in such latter event, all computations and payments
  hereunder, pending final determination of the proceeding, shall be based upon
  such original tax bill, with retroactive adjustment to be made following such
final determination.

43. OPERATING COST INCREASE

As used in this Paragraph: (A) Operating Costs shall mean all reasonable costs and expenses and taxes thereon, if any, paid or incurred by Owner or on behalf of Owner with respect to the operation, cleaning, repair,
safety, management, security and maintenance of the demised premises and the Building containing same, and the parking area and other Common Areas (as defined below), in a manner consistent with that of buildings of similar type and quality in the
vicinity of the Building, including but not limited to the following: (a) salaries, wages and bonuses paid to, and the cost of any hospitalization, medical, surgical, union and general welfare benefits (including group life insurance, any pension,
retirement or life insurance plan and other benefit or similar expense relating to, employees of Owner engaged in the operation, cleaning, repair, safety, management, security or maintenance of the Building or in providing services to tenants of the
Building; (b) social security, unemployment and other payroll taxes, the cost of providing disability and workmens

then prevailing management fees charged for comparable buildings in the metropolitan area containing the Building; and (p) maintenance, repair, striping, sweeping, and snow plowing of the parking area, curbs, and sidewalks. The preceding list is for
definitional purposes only and shall not impose any obligation upon Landlord to incur such expenses or provide such service, except if stated elsewhere in this Lease. Common Areas shall include all common facilities and shall mean all areas, space,
equipment, signs and special services provided by Landlord for the common or joint use and benefit of the occupants of the building, and their employees, agents, servants, customers and other invitees, including without limitation, parking areas,
elevators, roofs, stairs, hallways, curbs and sidewalks.

(B) Operating Cost Base Year shall be the calendar year 2009.

(C) Operating Cost Base
  shall mean the Operating Costs for the Operating Cost Base Year (whether
  or not retroactively determined).

(D) Tenants Proportionate Share shall mean 0.68percent.

(E) If the Operating
  Costs for any calendar year during the term of this Lease shall increase above
  the Operating Costs for the Operating Cost Base Year, then Tenant shall pay
  to Landlord as additional rent 0.68%of such increase. During the first
  calendar year  following the Operating Cost Base Year, the amount due hereunder
  shall be paid by Tenant within ten (10) days after Landlord shall submit a
  statement to Tenant, showing in reasonable detail the computation of the amount,
  if any, due hereunder to  Landlord. Any such Operating Cost increase for the
  calendar year in which this Lease shall end shall be apportioned accordingly.

If the Operating Costs shall be changed at any time during
  the remainder of the term of this lease after the Operating Cost Base Year,
  so that the Operating Costs shall then exceed the Operating Cost Base, Tenant
  shall pay as additional rent the sum equal to Tenants Proportionate Share
  of the amount by which the Operating Costs for the respective calendar year
  are greater than the Operating Cost Base, as an estimate of the Operating Cost
  Expense for the coming calendar year, in equal monthly installments commencing
  with the first monthly installment of fixed rent falling due hereunder on or
  after the effective date of such change in the Operating Costs and continuing
  thereafter until a new adjustment shall have become effective in accordance
  with the provisions of this Paragraph 43. Following the end of each calendar
  year, an adjustment shall be made based on the actual Operating Cost Expenses
  for said calendar year, and Tenant shall pay Landlord any difference between
  the estimated (billed) and actual figures within ten (10) days after Landlord
  shall submit a statement to Tenant. In no event shall Landlord be obligated
  to refund any sums to Tenant if the Operating Cost Expenses are less than the
Operating Cost Base.

Every notice given by Landlord pursuant to this Paragraph 43 shall be conclusive and binding upon Tenant unless (i) within five (5) days after the receipt of such notice Tenant shall notify Landlord that it disputes the
correctness of the notice,

4

---



specifying the particular respects in which the notice is
  claimed to be incorrect, and (ii) if such dispute shall not have been settled
  by agreement, Tenant shall submit the dispute to arbitration pursuant to this
  lease within ten (10) days after receipt of the notice. Pending the determination
  of such dispute by agreement or arbitration as aforesaid, the Tenant shall
  pay additional rent or accept credit in accordance with Landlords notice and such payment or acceptance
shall be without prejudice to Tenants position. If the dispute shall be determined in Tenants favor, Landlord shall forthwith pay Tenant the amount of Tenants overpayment of rents resulting from compliance with Landlords
statement.

44. ELECTRICITY

(a) As long as Tenant is not in default in the payment
  of any rent or the performance of any covenants of this lease on Tenants part to be performed, Landlord shall furnish to the demised premises Standard Electrical
Service for Tenants requirements for lighting and electrical appliances
and equipment within the demised premises. In addition to the annual rental rate
as specified on the front page of this Lease and additional rent as specified
elsewhere herein, Tenant shall pay for the electricity used in the demised premises
at the rate of $1,570.50 per annum, payable in equal monthly installments of $130.88,
and the aforesaid amount shall be deemed further additional rent and shall be
paid on the first day of each and every month. Landlord reserves the right to
have an electrician survey the demised premises (at Landlords sole cost and expense) to determine the actual electric consumption of Tenant. In the event the survey indicates that Tenants
actual electric consumption exceeds the foregoing amount, Tenant shall pay the
increased amount as additional rent from the date of the survey through the expiration
of the term of this Lease.

Tenant also agrees to purchase from Landlord or its agent
  all lamps, starters, ballasts or bulbs used in the demised premises. Tenants
  use of electricity in the demised premises shall be for the operation of lighting,
  business machines such as personal computers and other small office machines
  and lamps, and shall not at any time exceed the capacity of any of the electrical
conductors and equipment in or otherwise serving the demised premises.

In order to insure that such capacity is not exceeded and
  to avert possible adverse effect upon the building electric service, Tenant
  shall not, without Landlords prior written consent in each instance, connect any
additional fixtures, appliances or equipment (other than lamps, personal computers, and similar small office machines) to the buildings electric distribution system or make any alteration or addition to the electric system of the demised
premises existing at the commencement of the term of the lease. Should Landlord grant such consent, all additional risers or other equipment required therefor shall be installed by Landlord and the cost thereof shall be paid by the Tenant upon
Landlords demand. As a condition to granting such consent, Landlord may
require that the Tenant agree to an increase in the fixed rent by an amount which
will reflect the value to the Tenant (determined by the current public utility
rates for direct purchase by Tenant) of the additional services to be furnished
by the Landlord.

If the public utility rate schedule for the supply of electric
  current to the building shall be increased or decreased during the term of
  this lease, the amount defined in this Paragraph as Tenants cost for electricity
shall be equitably adjusted to reflect the resulting increase or decrease in Landlords cost of furnishing electric service to the demised premises. Landlord reserves the right to discontinue furnishing electric energy to the Tenant in the
demised premises at any time upon not less than thirty (30) days written
notice to the Tenant. If Landlord exercises such right of termination, this lease
shall

5

---



continue in full force and effect and shall be unaffected
  thereby except only that from and after the effective date of such termination
  Landlord shall not be obligated to furnish electric energy to the Tenant and
  the Tenants cost for electricity under this Paragraph shall be adjusted to reflect the resulting decrease in Landlords cost of furnishing electric service to the demised premises.  If Landlord so discontinues furnishing electric service to
Tenant, Tenant shall arrange to obtain electric energy directly from the public utility company furnishing electric services to the building. Such electric energy may be furnished to Tenant by means of the then existing building system feeders,
risers and wiring to the extent that same are available, suitable and safe for such purposes.  All meters and additional panel boards, feeders, risers, wiring and other conductors and equipment which may be required to obtain electric energy
directly from such public utility company shall be installed by the Landlord at Tenants
expense.

45. ASSIGNMENT AND SUBLETTING

(a) Tenant covenants and agrees that it will not, by operation
  of law or otherwise, assign, mortgage or encumber this lease, nor sublet or
  permit the demised premises or any part thereof to be used by others without
  Owners
prior written consent in each instance, which consent shall not be unreasonably withheld. In determining whether to grant consent to Tenants sublet or assignment request, Landlord may consider any reasonable factor. Landlord and Tenant agree
that any one of the following factors, or any other reasonable factor, will be reasonable grounds for deciding Tenants
request:

| | (i)   | financial strength of
        the proposed subtenant/assignee must be at least equal to that of the
    existing tenant;

| |       |                                                                                                                                         
| | (ii)  | business reputation of the proposed
        subtenant/assignee must be in accordance with generally acceptable commercial
    standards;
| |       |                                                                                                                                         
| | (iii) | use of the premises by the proposed
    subtenant/assignee must be identical to the use permitted by this lease;                        
| |       |                                                                                                                                         
| | (iv)  | managerial and operational skills
        of the proposed subtenant/assignee must be the same as those of the existing
    tenant;      
| |       |                                                                                                                                         
| | (v)   | use of the premises by the proposed
        subtenant/assignee will not violate or create any potential violation
    of any laws;      
| |       |                                                                                                                                         
| | (vi)  | use of the premises
        will not violate any other agreements affecting the premises, the Landlord
    or other Tenants.            

In no event may Tenant sublet all or any part of the demised
  premises, assign this lease in any manner or otherwise permit the occupancy
  of all or any part of the demised premises to any tenant, assignee, sublessee
  or other occupants of the building of which the demised premises forms a part.
  Any such request by Tenant to sublease all or any part of the demised premises,
  assign this lease in any manner or otherwise permit the occupancy of all or
  any part of the demised premises to any party who is a tenant, former tenant,
  assignee, sublessee or other occupancy of space in the building of which the
  demised premises forms a part shall not be subject to the terms of this numbered
  Article 45 hereof. Such
party is hereinafter referred to as a Prohibited Party. The consent by Owner to any assignment or subletting shall not in any manner be construed to relieve Tenant from obtaining Owners
express written consent to any other or further assignment or subletting.

6

---



(b) Tenant may without Owners prior written consent, assign this lease to a corporation or other business entity (herein sometimes called a successor corporation) into or with which Tenant shall be merged, or
consolidated, or a wholly owned or controlled corporation, or a franchisee, provided that the successor corporation shall use the demised premises only for the purpose specified in Paragraph 2 of this lease and provided further that there is
delivered to Owner within five (5) business days after the effective date of such assignment, an instrument duly executed and acknowledged by the assignee whereby assignee assumes performance of Tenants obligations under this lease, as well as
a true copy of the instrument of merger or consolidation, if the transaction wherein the assignment is made be one of merger or consolidation, or proof satisfactory to Owner that such assignment is to a wholly owned or controlled corporation, if the
transaction wherein the assignment is made be one to a wholly owned or controlled corporation. If Tenant requests Owners consent to any other assignment of this lease or subletting of all or any portion of the demised premises, other than to a
Prohibited Party, it shall submit in writing to Owner, at the time
it requests such consent:

(i) the name and address of the proposed assignee or subtenant;
  (ii) the terms and conditions of the proposed assignment or subletting; (iii)
  the nature and character of the business of the proposed assignee or subtenant;
  and (iv) banking, financial and other credit information relating to the proposed
  assignee or subtenant, reasonably sufficient to enable Owner to determine the
proposed assignees or subtenants financial responsibility.

(c) Owner shall have the following options to be exercised
  by written notice to Tenant within thirty (30) business days after Tenants aforesaid request for Owners consent, which request shall be deemed sufficient upon
which Owner must act only if the four (4) conditions in subparagraph (b) above have been complied with to Owners
reasonable satisfaction:

(i) If the request be for Owners consent to an assignment,
  Owner may require Tenant to execute an assignment to Owner, or to anyone designated
  by Owner, without payment of any premium therefor, provided that concurrently
  with the delivery of such assignment Owner, for itself and for any successor
  in interest as Owner, will execute and deliver an instrument releasing and
  discharging the Tenant from all obligations under this lease accruing after
  the effective date of such assignment but if said assignment be a pro tanto
  assignment, then such release and discharge shall relate to only so much of
the demised premises as is covered by such assignment;

(ii) If the request be for Owners consent to a sublease,
  Owner may require Tenant to execute a sublease to the Owner and/or its designee
  for the same term as the proposed sublease and upon the same terms and conditions
  as are contained in the proposed sublease except that the Owner or its designee
  shall not be required to pay any monies under said sublease other than reserved
  rent and additional rent at the same annual rate payable by Tenant under this
  lease, but prorated and apportioned according to the number of square feet
  of rentable area contained in the sublet premises, and except further, that
  Owner or its designee shall not be required to pay any premium therefor or
  perform any work thereunder as subtenant (for the purpose of readying the sublet
  premises for use), and except further, that the sublease shall provide for
  the unqualified right on the part of the subtenant to sub-sublet or assign
  the sublease to others for any lawful purpose and to alter the sublet premises
  in any manner Owner or its designee shall desire. Concurrently, with the delivery
  of the sublease to Owner, Owner, for itself and for any successor in interest
  as Owner, will execute and deliver an instrument indemnifying and holding Tenant
  harmless from any loss of rent or for other damages which Tenant might sustain
by reason of the default of the sublessee under the sublease.

7

---



(d) If Owner shall not exercise any of its aforesaid options within the time limited therefor, and if the use of the demised premises remains unchanged and the financial responsibility of the proposed assignee or subtenant be
reasonably acceptable to Owner, its consent to the proposed assignment or subletting shall not be withheld, provided, however, that each of the following conditions is first complied with:

(i) Tenant shall not then be in default under this lease;

(ii)
  If the proposed assignment or subletting be of the entire demised premises,
  the assignee
  or sublessee as the case may be, shall execute an agreement, in form reasonably
  satisfactory to the Owner, whereby such proposed assignee or sublessee assumes
  performance of Tenants obligations under this lease and
shall become jointly and severally liable with the Tenant for the performance
  thereof. If the proposed subletting be of less than the entire demised premises,
  sublessee shall execute and deliver a pro rata assumption of Tenants
lease obligations;

(iii) A duplicate original of the instrument of assignment or sublease, as the case may be, and of the assumption agreement duly executed by the appropriate party, shall be delivered to the Owner before the assignee or sublessee
shall be let into possession of the demised premises or the sublet portion thereof.

(iv) Tenant shall pay the sum of Five Hundred Dollars ($500.00) representing attorneys fees
  incurred by Owner in connection with the review and/or preparation and/or execution
  of any documents submitted to Owner relating to the proposed assignment or
subletting.

(e) If Owners written consent to a subletting shall have been obtained, Tenant shall pay to Owner, as additional rent hereunder due on the 1st day of each month of the term of the sublease, an amount equal to 100% of the
annual sublet rent in excess of the annual rent payable hereunder, except that if the sublet be for less than all of the demised premises, appropriate pro rata adjustment of the rent payable under this lease shall be made in determining the excess
of sublet rental over the pro rated rental payable under this lease. Rent or Rental as
used herein shall mean the aggregate of reserved or fixed rent and any additional
rent payable under the pertinent sublease, and such aggregate payable under the
within lease.

(f) Each of the foregoing provisions and conditions shall
  apply to each and every further attempted assignment or subletting other than
  to a Prohibited Party. An assignment of lease or a subletting as above provided
shall not discharge or release from liability hereunder the Tenant or any other person, firm, or corporation which shall have previously assumed Tenants
obligations hereunder, such liability to remain and continue for the balance
of the term with the same force and effect as though no assignment had been effected.

(g) The transfer in the aggregate of fifty percent (50%)
  or more of (i) the voting stock of any corporate tenant or (ii) the voting
  interest in any partnership tenant shall be deemed an assignment within the
  meaning of Article
11 of this lease and of this numbered Article, and shall require Owners
prior written consent, which consent will not be unreasonably withheld upon compliance
with all of the conditions set forth in subdivisions (a), (b), (c) and (d) hereof.
The provisions hereof shall not apply to the transactions described in the first
sentence of (b) hereof.

(h) The provisions of this Article shall apply only to
  an assignment of this lease by the initial Tenant and to a subletting of all
  or any portion of the demised premises by the initial Tenant to other than
  a Prohibited
Party and shall not apply to any other transaction providing for occupancy of all or any portion of the demised premises by a (i) third party other than the Tenants assignee or Tenants sublessee or (ii) an assignment or subletting
to a Prohibited Party.  For such other transactions, the provisions of Article 11 shall
apply.

  to assign the same pursuant to the provisions of the Bankruptcy Code, 11 U.S.C.
  S 101 et seq. (the Bankruptcy Code) to any person or entity who shall have
made a bona fide offer to accept an assignment of this lease on terms acceptable to Tenant, then notice of such proposed assignment, setting forth (i) the name and address of such proposed person, (ii) all of the terms and conditions of such offer,

to a court of competent jurisdiction for authority and approval to enter into
such assignment and assumption, and Landlord shall thereupon have the prior right
and option, to be exercised by notice to Tenant given at any time prior to the
effective date of such proposed assignment, to accept an assignment of this lease
upon the same terms and conditions and for the same consideration, if any, as
the bona fide offer made by such person, less any brokerage commission which
may be payable out of the consideration to be paid by such person for the assignment
of this lease.

Furthermore, as one element (but not the exclusive element)
  of the adequate assurance (as stated in (iii) above) that such a trustee must
  provide Landlord for the future performance by any such assignee of Tenants
obligations under this lease, there shall be deposited with Landlord within ten (10) days of demand therefore, to beheld pursuant to the provisions of Paragraph 30 hereof in addition to any other prepaid rent or security previously deposited with
Landlord the amount of at least one (1) full years annual reserved rent
and any additional rent (at the then current level of annual reserved rent and
additional rent on the effective date of such assignment) to secure the full
and faithful performance of the obligations of Tenant hereunder. In addition,
adequate assurance shall mean that any such assignee of this lease shall have
a net worth, exclusive of good will, equal to at least fifteen (15) times the
aggregate of the annual reserved rent reserved hereunder plus all additional
rent for the preceding calendar year.

(b)  If this lease is assigned to any person or entity
  pursuant to the provisions of the Bankruptcy Code, any and all monies or other
  considerations payable or otherwise delivered in connection with such assignment
  shall be paid or delivered to Landlord, shall be and remain the exclusive property
  of Landlord, and shall not constitute property of Tenant or of the estate of
  Tenant within the meaning of the Bankruptcy Code. Any and all monies or other
  considerations constituting Landlords property under the preceding sentence
  not paid or delivered to Landlord shall be held in trust for the benefit of
Landlord and shall be promptly paid to Landlord.

(c) Any person or entity to which this lease is assigned pursuant to the provisions of the Bankruptcy Code, shall be deemed without further act or deed to have assumed all of the obligations arising under this lease on and after
the date of such assignment. Any such assignee shall upon demand execute and deliver to Landlord an instrument confirming such assumption.

(d) Nothing contained in this Paragraph 46(A) shall, in any way, constitute a waiver of the provisions of this lease relating to assignment. Tenant shall not, by virtue of this Paragraph 46(A), have any further rights relating to
assignment other than those granted in the Bankruptcy Code.

(e) Notwithstanding anything in this lease to the contrary, all amounts payable by Tenant to or on behalf of Landlord under this lease, whether or not expressly denominated as rent, shall constitute rent for the purposes of
Section 502(b)(7) of the Bankruptcy Code.

(f)  The term Tenant as used in this Paragraph
  46(A) includes any trustee, debtor in possession, receiver, custodian or other
similar officer.

(B) DEFAULT: If the Tenant shall: (a) default in the payment
  of the annual rent reserved herein or any item or additional other payment
  herein provided; or (b) default in the observance of any of the other terms,
  covenants and conditions of this lease and such default shall continue for
  more than fifteen (15) days after such written notice of such default, or if
  the demised premises shall be abandoned, deserted or vacated, or if this lease
  shall be assigned or pass to or devolve upon one other than Tenant, except
  as herein provided, or if the entire demised premises shall be abandoned or
  deserted or be occupied by someone other than Tenant; or (c) if any tenant
  then in possession of the demised premises (including but not limited to any
  assignee or subtenant of Tenant) shall make any assignment for the benefit
  of creditors or file a voluntary petition in bankruptcy or be by any court
  adjudicated a bankrupt or take the benefit of any insolvency act or be dissolved,
  voluntarily or involuntarily, or if a receiver or trustee of Tenant and/or
  its property shall be appointed in any proceedings other than bankruptcy proceedings
  and such appointment, if made in proceedings instituted by the tenant then
  in possession, shall not be vacated within ten (10) days after it has been
  made, or if made in proceedings instituted by other than the tenant then in
  possession, shall not be vacated within forty-five (45) days after it has been
  made, or if Tenant shall fail to move into or take possession of the demised
  premises upon the Term Commencement Date of which fact Landlord shall be the
  sole judge; or (d) Tenant shall record or attempt to record this lease or any
  memorandum, assignment or other instrument relative to this lease; or (e) if
  Tenant shall default in the performance of any covenant of this lease (including
  the covenant to pay rent) more than six (6) times, in the aggregate, during
  the term of this lease, then notwithstanding that such defaults shall have
  been cured within the period after notice as above provided, any further similar
  default shall be deemed to be deliberate and Landlord shall not be required
  to afford Tenant an opportunity to cure such default; then, upon the happening
  of any one or more of the defaults or events above mentioned in this Paragraph
  46, this lease and the Term hereof shall upon the date specified in a notice,
  which date shall be not less than three (3) days after the date of mailing
  of such notice by Landlord to Tenant, wholly cease and expire, with the same
  force and effect as though the date so specified were the date hereinabove
  first set forth as the date of the expiration of the Term (but Tenant shall
  remain liable to Landlord as hereinafter provided); and thereupon, or at any
  time thereafter, Landlord may reenter the demised premises either by force
  or otherwise, and have the possession of the same as of its former estate,
  and/or may recover possession thereof in the manner prescribed by the statute
  relating to summary proceedings, or similar statutes (but Tenant shall remain
  liable to Landlord as hereinafter provided), it being understood that no demand
  for the rent and no reentry for condition broken and no notice to quit possession
  or other notices prescribed by statute shall be necessary to enable Landlord
  to recover such possession, but that all right to any such demand and any such
  reentry and any notice to quit possession or other statutory notices or prerequisites
are hereby expressly waived by Tenant.

(C).  In case of any such
  default, reentry, expiration and/or dispossess by summary proceedings or otherwise:
  (1) the rent and additional rent shall become due thereupon and be paid up
to the time of such reentry, dispossess and/or expiration,

10

---



together with such expenses as Landlord may incur for legal
  expenses, attorneys fees, brokerage, and/or putting the demised premises in good order, or for preparing the same for rerental;  (2) Landlord may relet the demised
premises or any part or parts thereof, either in the name of Landlord or otherwise, for a term or terms which may at Landlords option be less than or exceed the period which would otherwise have constituted the balance of the Term and may
grant concessions or free rent; and (3) Tenant or the legal representatives of Tenant shall also pay Landlord as liquidated damages for the failure of Tenant to observe and perform said Tenants covenants herein contained, any deficiency
between the rent hereby reserved and/or covenanted to be paid and the net amount, if any, of the rents collected on account of the lease or leases of the demised premises for each month of the period which would otherwise have constituted the
balance of the Term. In computing such liquidated damages there shall be added to the said deficiency such expenses as Landlord may incur in connection with reletting, such as legal expenses, attorneys fees,
brokerage and for keeping the demised premises in good order or for preparing
the same for reletting. Any such liquidated damages shall be paid in monthly
installments by Tenant on the rent day specified in this lease and any suit brought
to collect the amount of the deficiency for any month shall not prejudice in
any way the rights of Landlord to collect the deficiency for any subsequent month
by a similar proceeding.

(D). In case of any default,
  reentry, expiration and/or dispossess, by summary proceedings or otherwise,
  pursuant to this Paragraph 46, Landlord shall (notwithstanding any other provisions
  of this lease) be entitled, at its option, in addition and without prejudice
  to any other rights and remedies it may have hereunder or at law or in equity,
  to recover from Tenant as damages, in addition to any unpaid rent and any additional
  rent accrued to the date of such reentry, expiration and/or dispossess, an
  amount equal to the difference between the rent and additional rent reserved
  hereunder for what would otherwise have been the unexpired portion of the Term
  (had such reentry, expiration and/or dispossess not occurred) and the then
  fair and reasonable rental value of the demised premises for such unexpired
  portion of the Term, both discounted at the rate of four (4%) percent per annum
  to present worth. Landlord shall be entitled to recover and receive the full
  amount of such damages at whatever time after such reentry, expiration and/or
  dispossess it seeks to recover the same. However, nothing herein contained
  shall limit or prejudice the right of Landlord to prove for and obtain as damages,
  by reason of the default or other event or occurrence as a result of which
  such reentry, expiration and/or dispossess shall have occurred, an amount equal
  to the maximum amount allowed by any statute or rule of law in effect at the
  time when, and governing the proceedings in which, such damages are to be proved,
  whether or not such amount be greater, equal to or less than the amount of
  the difference referred to above. In determining the then fair and reasonable
  rental value of the demised premises, the rental realization upon any reletting,
  if such reletting shall be accomplished within a reasonable time after such
  reentry, expiration and/or dispossess, shall be deemed prima facie to be such
  rental value. Landlord shall be entitled, in addition, to the amount of such
  difference, to also recover such expenses as Landlord may incur in connection
  with such reentry and/or dispossess and such reletting, such as legal expenses,
  attorneys fees,
brokerage and the costs and expenses incurred in connection therewith and in
  keeping the demised premises in good order and in preparing the same for such
reletting.

(E). Landlord at Landlords option may make such alteration, repairs, replacements and/or decoration in the demised premises as Landlord, in Landlords
  sole judgment, considers advisable and necessary for the purpose of reletting
  the demised premises; and the making of such alterations and/or decorations
  shall not operate or be construed to release Tenant from liability hereunder
  as aforesaid. Landlord shall in no event be liable in any way whatever for
  failure to relet the demised premises, or in the event that the demised premises
are relet, for failure to collect the rent thereof under such reletting.

11

---



(F).  In the event of a breach
  or threatened breach by Tenant of any of the covenants or provisions of this
  lease, Landlord shall have the right of injunction and the right to invoke
  any remedy allowed at law or in equity as if reentry, summary proceedings and
  other remedies were not herein provided for. Mention in this lease of any particular
remedy shall not preclude Landlord from any other remedy, in law or in equity.

(G). No receipt of rent or
  additional rent by Landlord from Tenant after the termination in any way of
  this lease or after giving any notice, shall reinstate, continue or extend
  the Term, or affect any notice. No receipt of rent or additional rent after
  the commencement of suit, or after final judgment for possession of the demised
  premises, shall reinstate, continue or extend the Term or affect said suit
or said judgment.

(H). In the event that Landlord should retain an attorney (whether or not suit be brought) to obtain possession of the demised premises, for recovery of any sum due under or because of breach of, any
covenant of this lease, or for any other relief against Tenant, declaratory or otherwise, or should Tenant bring any suit for any relief against Landlord, declaratory or otherwise, arising out of this lease, and Landlord should prevail in any such
suit, Tenant agrees to pay Landlord as additional rent all costs, expenses and reasonable attorneys fees
that Landlord may have incurred in connection therewith, which shall be deemed
to have accrued on the date such attorney is retained and shall be enforceable
whether or not a suit is prosecuted to judgment.

(I)  Notwithstanding anything to the contrary contained
  in 46(A) through 46(H) above or elsewhere in this Lease, if Tenant shall default
  in the payment when due of minimum rent or additional rent, Landlord may elect
  to declare all rent payable under this Lease by Tenant to Landlord due any
  payable, and, if Landlord shall make such election, such rent shall be due
  and payable within five (5) days after Landlords notice to Tenant of
such election.

47. LIMITATION OF LIABILITY

  the limited liability company shall not be liable with respect to any of the
  provisions of this lease, and if such Owner is in breach or in default with
  respect to its obligations or otherwise under this lease, Tenant shall look
  solely to the interest of such Owner in the property of which the demised premises
  form a part, for the satisfaction of Tenants remedies, and no other property
  or assets of such Owner shall be subject to levy, execution or other enforcement
  procedure for such satisfaction, it being understood and agreed that the members
  of Owner (and any partners, officers, directors, and/or shareholders of such
  members) shall not be liable in any way whatsoever for any of the obligations
of Owner hereunder.

48. BROKER

Tenant warrants and represents that it negotiated the within lease through PLAWKER REAL ESTATE, INC. as broker, and without the aid, intervention or employment of any
other broker. Tenant agrees to indemnify Owner against any claim by any other broker dealt with by Tenant with regard to this Lease, any extension, renewal, or option exercised by Tenant for the demised premises (whether specifically referenced
herein or not), and any lease for other space in the subject building (whether entered into during the original lease term or subsequent thereto), and to defend, at its own cost and expense, any claim brought by any other broker for commission
resulting from this Lease, any extension, renewal, or option exercised by Tenant for the demised premises (whether specifically referenced herein or not), and any lease for other space in the subject building (whether entered into during the
original lease term or subsequent thereto).

but at the sole cost and expense of Tenant, flooring or ceiling reinforcements and sound absorbent material as may be necessary in the area where such machines may from time to time be located, and Tenant agrees to pay the cost thereof within five
(5) days after presentation of bills covering the same, the amount of which costs shall be deemed to be paid as additional rent.

50. Tenant shall not at any time prior to or during the term of this lease, either directly or indirectly, use any contractors and/or labor and/or materials whose use creates or would create difficulty with other contractors
and/or labor engaged by Tenant or Landlord or others in the maintenance, and/or operation of the demised premises or the building.

51.  All alterations, additions and improvements made by
  Tenant at its own cost and expense, and all furniture, removable partitions
  and trade fixtures installed by Tenant at its own cost and expense shall remain
  the property of the Tenant and on or before the expiration of the term shall
  be removed from the demised premises by Tenant and Tenant, at its own cost
  and expense, shall repair any damage to the demised premises caused by such
  installation or removal and shall restore the premises to good order and condition
  on or before the expiration of the term of this lease. Any property (including
  but not limited to personal property, furniture, and equipment) remaining in
  the demised premises after the expiration of the term of this Lease or sooner
  termination thereof shall, at the election of Landlord, be deemed abandoned,
  in which case Landlord shall be entitled to dispose of such property without
liability at Tenants sole cost and expense.

52. AS IS

Tenant has thoroughly examined the herein demised premises
  and is fully familiar with the condition thereof. Tenant agrees to accept the
  said premises as is and in such condition as the same may be at the date of
commencement of the term of this lease, and Landlord shall not be obligated or required to do any work or to make any alterations or install any fixtures, equipment or improvements, or to make any repairs to or in the demised premises in order to
fit the same for Tenants use.

53. ESTOPPEL CERTIFICATE

Tenant shall, without charge, at any time and from time to time thereafter, within ten (10) days after written request of Landlord, certify by a written instrument duly executed and acknowledged to any mortgagee or purchaser, or

54.  Landlord does not warrant that any governmental license
  permitting any particular business to be carried on in the demised premises
  will be granted, or if granted, will be continued in effect or renewed. If
  any governmental license or permit shall be required for the lawful conduct
  of Tenants business, Tenant shall duly procure and thereafter maintain such license or permit and submit the same to Landlord for inspection, it being understood and agreed that
Tenants obligation under this lease shall in no wise be affected or impaired by reason of Tenants inability to secure and/or maintain the same. Tenant shall at all times comply with the terms and conditions of each such license or
permit. Landlord agrees to cooperate with Tenant for the purpose of obtaining any such license or permit and to execute any documents or instruments necessary in connection therewith, all at Tenants
expense.

55. Tenant

  . Additionally, Tenant shall duly complete a W-9 Form
(IRS) or any other such similar form, and return same promptly to Landlord.

56.  All checks tendered to Landlord as and for the rent and/or additional rent required hereunder shall be deemed payments for the account of Tenant. Acceptance by Landlord of rent and/or additional rent from anyone other than
Tenant shall not be deemed to operate as an attornment to Landlord by the payor of such rent and/or additional rent or as a consent by Landlord to an assignment of this lease or subletting by Tenant of the demised premises to such payor, or as a
modification of any of the provisions of this lease.

57. ALLOCATION OF ARREARAGE

If Tenant is in arrears in the payment of rent or additional
  rent, Tenant waives Tenants rights, if any, to designate the items against
  which any payments made by Tenant are to be credited, and Tenant agrees that
  Landlord may apply any payments made by Tenant to any item Landlord sees fit,
  irrespective of and notwithstanding any designation or request by Tenant as
to the items against which any such payments shall be credited.

58. PAYMENTS

No payment by Tenant or receipt or acceptance by Landlord
  of a lesser amount than the current fixed rent or additional charges shall
  be deemed to be other than a payment on account nor shall any endorsement or
  statement on any check or any letter accompanying any check or payment be deemed
  an accord and satisfaction, and Landlord may accept such check or payment without
  prejudice to Landlords right to recover the balance and pursue any other
remedy in this lease or as provided by applicable laws.

59. ADVANCES MADE FOR TENANT

Tenant shall repay to Landlord any sum of money which Landlord
  shall pay or the cost of any performance by Landlord because of the failure
  of Tenant to perform any one or more of the other provisions or conditions
  in this lease on the part of Tenant to be performed or observed, provided in
  each instance Landlord shall have given Tenant at least ten (10) days prior
  written notice before paying such sum and/or performing such obligations (except
  in emergencies, where no such notice shall be required) and Tenant shall have
  failed to perform or observe such provisions or conditions. No such payment
  or performance by Landlord shall excuse or discharge Tenants failure to perform or shall be a waiver of any of
Landlords rights with respect to such failure to perform or to insist on
strict performance at any time thereafter. The sum or sums so paid by Landlord
together with interest and all costs, damages and reasonable counsel fees actually
incurred by Landlord, shall be payable by Tenant as additional rent with the
next installment of base rent.

---



60. ADDITIONAL RENT

All items payable by Tenant to Landlord hereunder with the exception of base rent shall be deemed additional rent, and all additional rent and other charges payable under this lease shall be paid without any setoff or deduction
except as otherwise expressly provided above. Landlord shall have the same rights and remedies for the nonpayment of additional rent and other charges under this lease as for nonpayment of base rent.

61. LANDLORDS CONSENT WITHHELD

Except as otherwise specifically provided herein, if Tenant
  shall request Landlords approval or consent and Landlord shall fail or refuse to give such consent or approval, Tenant shall not be entitled to any damages for any
withholding or delay of such approval or consent by Landlord, it being intended that Tenants
sole remedy shall be an action for injunction or specific performance and that
such remedy shall be available only in those cases where Landlord shall have
expressly agreed in writing not unreasonably to withhold or delay its consent
or approval or where as a matter of law Landlord may not unreasonably withhold
or delay its consent or approval. Any refusal by Landlord to consent to or approve
any matter or thing requested by Tenant shall be deemed reasonable if, inter alia, the holder of any mortgage affecting the real
property of which the demised premises are a part has refused to give its consent or approval thereto wherever such consent or approval is necessary.

62. INDEMNITY

(A) Landlord or its agents shall not be liable for any
  damage to property of Tenant or of others which is entrusted to employees of
  the Building, nor for loss of or damage to any property of Tenant by theft
  or otherwise, nor for any injury or damage to persons, property or business
  resulting from or occasioned by explosion, falling plaster, electricity, smoke,
  water, snow or ice being upon or coming through or from the street, roof, walls,
  subsurface, skylight, trapdoor or window, electric wiring, plumbing, dampness,
  water, gas, steam or other pipes or sewage, or the failure of the air-conditioning
  or refrigeration system or other appliances, or the breaking of any electric
  wire, the bursting, leaking or running of water from any tank, bathroom, waste-pipe,
  sprinkler system, radiator, or any other pipe in, above, upon or about the
  Building or the demised premises or which may at any time hereafter be placed
  therein, or from any other cause of whatsoever nature; nor shall Owner be liable
  for any latent defect in the demised premises or the Building. It is understood
  that no property (specifically including animals), other than such as might
  be normally be brought upon or kept in the demised premises as incident to
  the reasonable use of the demised premises for the purposes herein permitted
  will be brought upon or be kept in the demised premises. Landlord and its agents
  shall not be liable for any loss of or damage to any such property even if
due to the negligence of Landlord or Landlords agents.

(B) Tenant shall indemnify and hold Landlord, Landlords agents, and the mortgagee under any mortgage affecting the Building, harmless of and from any and all loss, cost, liability, claim, damage and expense including
reasonable attorneys fees, penalties and fines incurred in connection with or arising from any injury to Tenant or to any other person or for any damage to, or loss (by theft or otherwise) of, any of Tenants
property or of the property of any other person, irrespective of the cause of

15

---



such injury, damage or loss (including the acts or negligence
  of any tenant or occupant of the Building or of Landlord or Landlords
  agents, or of any owners or their agents, or occupants of adjacent or contiguous
  property), in connection with or arising from the use, occupancy, manner of
  use or occupancy, conduct or management of the demised premises or of any business
  therein, or any work or thing whatsoever done, or any condition created in
  or about the demised premises during the term of this Lease or during the period
  of time, if any, prior to the Commencement Date that Tenant may have been given
  access to or taken possession of the demised premises, or in connection with
  or arising from any negligent or otherwise wrongful act or omission of Tenant
  or any of its subtenants or licensees or its or their employees, agents or
  contractors. In case any action or proceeding be brought by reason of any such
  claim, Tenant, upon notice from Landlord, shall resist and defend such action
  or proceeding (by counsel reasonably satisfactory to Landlord), unless Tenant
  causes the same to be promptly discontinued. Landlord or its agents shall not
  be liable for any such damage caused by other tenants or persons in, upon or
  about said Building, or caused by operations in construction of any private,
  public or quasi-public work. Tenant shall give immediate notice to Landlord
  in case of damage to the demised premises or the Building or of defects therein
or in any fixtures or equipment.

63. INSURANCE

At all times during the term of this lease, Tenant shall,
  at its own cost and expense, provide and keep in force for the mutual benefit
  of Landlord and Tenant, comprehensive general public liability insurance against
  claims for bodily injury, death or property damage occurring in or about the
  demised premises (including, without limitation, bodily and personal injury,
  death or property damage, resulting directly or indirectly from any change,
  alteration, improvement or repair thereof), in the amount of One Million Dollars
  ($1,000,000.00) combined single limit per occurrence, and umbrella liability insurance in the amount of Two Million Dollars ($2,000,000.00)
  . Such insurance policy is to be written by good and solvent insurance companies
  satisfactory to Landlord; said insurance may be carried under a blanket policy
  covering the demised premises and other locations of Tenant, if any. These policies shall name Goodrich
Executive L.L.C. and Goodrich Management Corp. as additional named insureds.

All insurance to be provided and kept in force by Tenant
  pursuant to this paragraph shall name Landlord and Tenant as insured, as their
  respective interests may appear. In addition, at Landlords request, the insurance
described in this Article shall name as an additional insured, the holders of any mortgages affecting the demised premises or which may in the future, affect the demised premises. Such insurance shall provide that as to the interest of Landlord, the
same shall not be invalidated by any act of omission of Landlord, Mortgagees, Tenant or any occupant of the demised premises. Said policies shall be in force and fully paid for by Tenant and the originals or duplicate original or, if such duplicate
originals cannot be obtained, then evidence of insurance in the form of an ACORD-27 together with a true copy of such policies, shall be delivered to Landlord before Tenant takes possession of the demised premises. Said policies shall be for a
period of not less than one (1) year and shall contain a provision whereby the same cannot be canceled or modified unless the Mortgagees and Landlord are given at least thirty (30) days prior
written notice of such cancellation or modification. Tenant shall procure and
fully pay for renewals of such insurance from time to time at least thirty (30)
days before the expiration thereof, and Tenant shall promptly deliver to Landlord
the originals or duplicate originals of the renewal policies or, if such duplicate
originals cannot be obtained, then evidence of insurance in the form of an ACORD-27
together with a true copy of such policies, shall be delivered to Landlord. In
the event that Tenant fails to make such delivery as of the Commencement Date
or at least fifteen

16

---



(15) days prior to the expiration date of any current policy or to maintain such insurance and pay the premiums therefor, Landlord shall have the right to cause such insurance policy to be issued and to pay the premiums therefor.
In such event, the cost thereof shall be added to the installment of fixed annual rent payable on the next monthly rent payment date and Tenant hereby agrees to pay at that time the installment of fixed annual rent and such additional rent then due.

All insurance policies carried by the Tenant shall contain
  standard waiver of subrogation provisions. The Tenant hereby releases and waives
  all right of recovery against the Landlord or anyone claiming through or under
  the Landlord by way of subrogation or otherwise, with respect to any damage
or injury caused by reason of the Owners carelessness or negligence.

Tenants failure to provide and keep in force the aforementioned insurance shall be regarded as a material default hereunder, entitling Landlord to exercise any or all of the remedies as provided in this lease in the event
of Tenants default.

63A. ADDITIONAL INSURANCE REQUIRED

In addition to the insurance described in Paragraph 63,
  at all times during the term of this lease Tenant shall, at its own cost and
  expense, provide and keep in force Workmens Compensation and Disability Insurance and
Employers Liability Insurance in limits required by applicable law in the state where the demised premises is located and any other states as necessary due to Tenants
operations.

64. WAIVER OF TRIAL BY JURY

It is mutually agreed by and between Landlord and Tenant
  that the respective parties hereto shall and they hereby do waive trial by
  jury in any action, proceeding or counterclaim brought by either of the parties
  hereto against the other (except for personal injury or property damage) on
  any matters whatsoever arising out of or in any way connected with this lease,
  the relationship of Landlord and Tenant, Tenants use of or occupancy
  of said demised premises, and any emergency statutory or any other statutory
  remedy. It is further mutually agreed that in the event Landlord commences
  any summary proceeding for possession of the demised premises, or any other
  action or proceeding against the Tenant or the demised premises, Tenant will
  not interpose any counterclaim of whatever nature or description in any such
proceeding.

65. HOLDING OVER

If the Tenant retains possession of the demised premises
  or any part thereof after the termination of the term by lapse of time or otherwise,
  without prior written approval of Landlord, the Tenant shall be deemed a holdover
  tenant and shall pay the Landlord rent at double the rate specified in Article 1 above for the time the Tenant thus remains in possession, and in addition thereto, shall pay the Landlord all damages, consequential as well as direct,
sustained by reason of the Tenants retention of possession. Without limiting the foregoing, Tenant shall indemnify Landlord against all claims for damages by any other tenant to whom Landlord may have leased all or any part of the demised
premises effective upon the termination of this Lease. The provisions of this Section do not exclude the Landlords
right of re-entry or any other right hereunder.

66. RIGHTS RESERVED BY LANDLORD

Without abatement or diminution in rent, Landlord reserves and shall have the following additional rights:

17

---



(a) To change the street address and/or the name of the building and/or the location of entrances, passageways, doors, doorways, corridors, elevators, stairs, toilets or other public parts of the building, or to change the
location of the demised premises, without liability to Tenant.

  interest, and (iv) to take material into and upon said premises in connection
therewith.

(d) At any time or times Landlord either voluntarily or
  pursuant to governmental requirement, may at Landlords own expense, make repairs, alterations or improvements in or to the building or any part thereof, and during
