but without extension for force majeure or the provisions of Section 13.03
below, in the event that Landlord fails to deliver possession of the Premises
as required hereby on or before May 1, 2009, then Tenant may terminate
this Lease, whereupon no further rights or obligations shall exist with respect

termination.  (d) Early Possession. Tenant shall have

loss or damage by fire or other casualty, damage or loss from a taking or sale
in lieu thereof, damage not resulting from the act or omission of Tenant, its
agents, employees, contractors or invitees or resulting from the act or
omission of Landlord or its employees, contractors, agents, invitees or

any damage caused by any such removal. All of Tenants Property that is not

termination, and otherwise upon the terms, covenants and conditions herein
specified, so far as applicable. Acceptance by Landlord of rent after such
expiration or earlier termination shall not result in a renewal of this Lease,
nor shall such acceptance create a month-to-month tenancy. In the event a
month-to-month tenancy is created by operation of law, either party shall have
the right to terminate such month-to-month tenancy upon thirty (30) days prior
written notice to the other, whether or not said notice is given on the rent
paying date. This Section 2.04 shall in no way constitute a consent
by Landlord to any holding over by Tenant upon the expiration or earlier
termination of this Lease, nor limit Landlords remedies in such event. The
foregoing notwithstanding, in no event shall Tenant be liable to Landlord for
any damages for the first fifteen (15) days of such holdover other than the
rent specified in the first sentence of this Section 2.04).  3

product of Tenants Proportionate Share times any increase in Real Estate Taxes
and Insurance Premiums over the Base Year of 2009.  (d)Real Estate Taxes shall mean any form of real estate tax or
assessment or service payments in lieu thereof, and any license fee, commercial
rental tax, improvement bond or other similar charge or tax (other than
inheritance, franchise, capital stock, income, profits, succession, or gift or
estate taxes) imposed upon the Building or Common Areas, or against Landlords
business of leasing the Building, by any authority having the power to so
charge or tax, to the extent that such items other than real estate taxes and
assessments would be payable if the Building were the only property of Landlord
subject thereto and the income received by Landlord from the Building were the
only income of Landlord (provided that Tenants Proportionate Share thereof
shall be based on its rent compared to the rent  5


received from all tenants of the Building if such tax is calculated in
that manner) together with costs and expenses of contesting the validity or
amount of the Real Estate Taxes, which Landlord shall do if reasonably prudent.  Notwithstanding the year for which any such Real Estate Taxes are
levied, in the case of Real Estate Taxes which may be paid in installments, the
minimum installment, plus any interest payable thereon, so payable during a
calendar year shall be included in Real Estate Taxes for that year Except as
otherwise provided herein, all references to Taxes for a calendar particular
year shall be deemed to refer to taxes payable for such year without regard to(1) when
such taxes are levied, assessed or imposed.  If there shall be any refund of any Operating Expenses at any time
during or after the Lease Term for any Operating Expenses incurred during the
Lease Term, Tenant shall be entitled to it pro rata share of the refund, after
Landlord deducts from the refund Landlords reasonable pro rata costs and
expenses in obtaining the same, and Landlord shall promptly pay Tenant the
same.  (e)Insurance Premiums shall mean insurance premiums for insurance
coverage on the Building or Common Areas and shall include all fire and
extended coverage insurance on the Building and all liability insurance
coverage on the Common Areas of the Building, and the grounds, sidewalks,
driveways and parking areas related thereto, together with such other insurance
coverages, including, but not limited to, rent interruption insurance, as are
from time to time obtained by Landlord.  Section 3.03. Payment of Additional Rent.  (a)Any amount required to be paid by Tenant
hereunder (in addition to Base Rent) and any charges or expenses incurred by
Landlord on behalf of Tenant under the terms of this Lease shall be considered Additional
Rent payable in the same manner and upon the same terms and conditions as the Base
Rent reserved hereunder, except as set forth herein to the contrary. Any
failure on the part of Tenant to pay such Additional Rent when and as the same
shall become due, and the continuance of such failure for any applicable grace
or cure period, shall entitle Landlord to the remedies available to it for non payment
of Base Rent.  (b)In addition to the Base Rent specified in
this Lease, commencing as of the Commencement Date, Tenant shall pay to
Landlord as Additional Rent for the Leased Premises, in each calendar year or
partial calendar year during the Lease Term, an amount equal to the Annual
Rental Adjustment for such calendar year. Landlord shall reasonably estimate
the Annual Rental Adjustment annually, and written notice thereof in reasonable
detail shall be given to Tenant prior to the beginning of each calendar year.
Tenant shall pay to Landlord each month, at the same time the Monthly Rental Installment
is due, an amount equal to one-twelfth (1/12) of the estimated Annual Rental
Adjustment. Tenant shall be responsible for delivering the Additional Rent to
the payment address set forth in Section 1.01(1) above in accordance
with this Section 3.03. If Operating Expenses increase or decrease
during a calendar year, Landlord may increase or decrease the estimated Annual
Rental Adjustment during such year by giving Tenant written notice to that
effect in reasonable detail, and thereafter Tenant shall pay to Landlord, in
each of the remaining months of such year, the first of which is at least
fifteen (15) days after such notice, an amount equal to the amount of such
increase or decrease in the estimated Annual Rental Adjustment divided by the
number of months remaining in such year. Within a reasonable time (but no later
than the next June 1) after the end of each calendar year, Landlord shall
prepare and deliver to Tenant a statement showing the actual Annual Rental
Adjustment for that year in reasonable detail. Within thirty (30) days after
receipt of the aforementioned statement, Tenant shall pay to Landlord, or Landlord
shall credit against the next rent payment or payments due from Tenant or pay
such amount to Tenant if this Lease has expired and the full amount thereof has
not been so fully credited, as the case may be, the difference between the
actual Annual Rental Adjustment for the preceding calendar year and the
estimated amount paid by Tenant during such year. This Section 3.03
shall survive the expiration or any earlier termination of this Lease.  Tenant and its designees shall have the right to inspect, at reasonable
times and in a reasonable manner, during the ninety (90) day period following
the delivery of Landlords statement of the actual amount of the Annual Rental
Adjustment, such of Landlords books of account and records as pertain to and
contain information concerning sucfy costs and expenses in order to verify the
amounts thereof, which books and records Landlord agrees to keep or cause to be
kept in accordance with sound accounting and management practices for a
reasonable period of time. Tenants failure to exercise its rights hereunder
within said ninety (90) day period shall be deemed a waiver of its right to
inspect or contest the method, accuracy or amount of the Annual Rental
Adjustment. In the event of any undisputed error, Landlord shall make a
correcting payment in full to Tenant within thirty (30) days after the
determination of the amount of such error. In the event of any errors on the
part of Landlord which Landlord agrees (or it is determined as provided below
in this Section 3.03) were errors in excess of five percent (5%) of Tenants
actual operating expense liability for any calendar year, Landlord will also
reimburse Tenant for costs (in an amount not to exceed $1,000.00) of an audit
reasonably incurred by Tenant within the above thirty (30) day period. If
within the period aforesaid, Tenant provides Landlord with its notice disputing
the correctness of the statement, and if such dispute shall have not been
settled by agreement, Landlord shall  6


submit the dispute to a reputable firm of independent certified public
accountants selected by Landlord and approved by Tenant, such approval shall
not be unreasonably withheld or delayed, and the decision of such accountants
shall be conclusive and binding upon the parties. If such accountant decides
that there was an error, the owing party will promptly make correcting payment.
The fees and expenses involved in such decision shall be borne by the
unsuccessful party.  With respect to any calendar year which does not fall entirely within
the Lease Term, Tenant shall be obligated to pay as an Annual Rental Adjustment
for such year only a pro rata share of Annual Rental Adjustment as hereinabove
determined, based upon the number of days of the Lease Term falling within such
year. Any payment made pursuant to this Section 3.03 shall be made without
prejudice to any right of the Tenant to dispute any items as billed pursuant to
the provisions hereof.  Section 3.04. Late Charges. Tenant acknowledges that Landlord shall
incur certain additional unanticipated administrative and legal costs and
expenses if Tenant fails to pay timely any payment required hereunder.
Therefore, in addition to the other remedies available to Landlord or Tenant
hereunder, if any payment required to be paid by Tenant to Landlord or Tenant
hereunder (other than accelerated rent that may be due after a Default by
Tenant hereunder) shall become overdue after any applicable grace or cure
period, such unpaid amount shall bear interest from the due date thereof to the
date of payment at the prime rate of interest, as reported in the Wall Street
Journal (the Prime Rate) plus six percent (6%) per annum.  ARTICLE 4 -
SECURITY DEPOSIT  Upon execution and delivery of this Lease by Tenant, Tenant shall
deposit the Security Deposit with Landlord as security for the performance by
Tenant of all of Tenants obligations contained in this Lease. In the event of
a default by Tenant, Landlord may apply all or any part of the Security Deposit
to cure all or any part of such default; provided, however, that any such
application by Landlord shall not be or be deemed to be an election of remedies
by Landlord or considered or deemed to be liquidated damages. Tenant agrees
promptly, upon demand, to deposit such additional sum with Landlord as may be
required to maintain the full amount of the Security Deposit. All sums held by
Landlord pursuant to this Article 4 shall be without interest and
may be commingled by Landlord. At the end of the Lease Term, provided that
there is then no uncured default or any repairs required to be made by Tenant
pursuant to Section 2.03 above or Section 7.03 below,
Landlord shall return the Security Deposit to Tenant.  ARTICLE 5 -
OCCUPANCY ANDUSE  Section 5.01. Use. Tenant shall use the Leased Premises for the Permitted Use and for no
other purpose without the prior written consent of Landlord.  Section 5.02. Covenants of Tenant Regarding Use.  (a)Tenant shall (i) use and, as herein required, maintain the Leased
Premises and conduct its business thereon in a safe, careful, reputable and
lawful manner, (ii) cause its use to comply with all current covenants
that encumber the Building (all of which Landlord hereby represents and
warrants to Tenant are referenced on Exhibit E attached hereto and
made a part hereof) and any reasonable modifications thereto or new covenants
that do not unreasonably interfere with Tenants use and enjoyment of the
Leased Premises and the Common Areas, and all laws, rules, regulations, orders,
ordinances, directions and requirements of any governmental authority or
agency, now in force or which may hereafter be in force, including, without
limitation, those which shall impose upon Landlord or Tenant any duty with
respect to or triggered by a change in the use or occupation of, or any improvement
or alteration to, the Leased Premises, and (iii) comply with and obey all
reasonable directions, rules and regulations of Landlord, including the
Building Rules and Regulations attached hereto as Exhibit P
and made a part hereof, as may be reasonably modified from time to time by
Landlord on reasonable notice to Tenant.  (b)Tenant shall not do or permit anything to be done in or about the
Leased Premises that will in any way cause a nuisance, obstruct or interfere
with the rights of other tenants or occupants of the Building of which Tenant
is aware and which are not contrary to the rights granted Tenant under this Lease
or injure or annoy them. Landlord shall not be responsible to Tenant for the
non-performance by any other tenant or occupant of the Building of any of
Landlords directions, rules and regulations, but agrees that any
enforcement thereof shall be done uniformly and agrees to take reasonable
measures to assure such other tenants and occupants compliance. Tenant shall
not overload the floors of the Leased Premises. All damage to the floor
structure or foundation of the Building due to improper positioning or storage
of items or materials by Tenant shall be repaired by Landlord at the sole
expense of Tenant, who shall reimburse Landlord within five (5) business
days after notice from Landlord with reasonable evidence thereof therefore upon
demand. Tenant shall not use the Leased Premises, nor allow the Leased Premises
to be used, for any purpose or in any manner that would (i) invalidate any
commercially reasonable policy of insurance now or hereafter carried by
Landlord on the Building, or (ii) increase the  7


rate of premiums payable on any such insurance
policy unless Tenant reimburses Landlord for any increase in premium charged.  Section 5.03. Landlords Rights Regarding Use. Without limiting any of Landlords rights
specified elsewhere in this Lease, so long as the same does not materially
adversely affect Tenants access to or use of the Leased Premises and the
Common Areas (a) Landlord shall have the right at any time, without notice
to Tenant, to control, change or otherwise alter the Common Areas in such
manner as it reasonably deems necessary or proper, and (b) Landlord, its
agents, employees and contractors and any mortgagee of the Building shall have
the right to enter any part of the Leased Premises at reasonable times upon
reasonable notice (except in the event of an emergency not allowing for any
advance notice where no notice shall be required) accompanied by an employee or
representative of Tenant, if available, for the purposes of examining or
inspecting the same (including, without limitation, testing to confirm Tenants
compliance with this Lease), showing the same to prospective purchasers,
mortgagees or, during the last twelve (12) months of Lease Term only, tenants,
and making such repairs, alterations or improvements to the Leased Premises or
the Building as Landlord may reasonably deem necessary or desirable, provided,
however, that any repairs made by Landlord shall be at Landlords expense
except as provided in Section 7.02 hereof. So long as the same does not
materially affect Tenants access to or use of the Leased Premises or Common
Areas, Landlord shall incur no liability to Tenant for such entry, nor shall
such entry constitute an eviction of Tenant or a termination of this Lease, or
entitle Tenant to any abatement of rent therefor.  ARTICLE 6 -
UTILITIES  Tenant shall obtain in its own name and pay directly to the appropriate
supplier the cost of all utilities and services serving the Leased Premises.
However, if any services or utilities are jointly metered with other property,
Landlord shall make a reasonable determination of Tenants proportionate share
of the cost of such utilities and services (at rates that would have been
payable if such utilities and services had been directly billed by the
utilities or services providers) and Tenant shall pay such share to Landlord
within fifteen (15) days after receipt of Landlords written statement.
Landlord shall not be liable in damages or otherwise for any failure or
interruption of any utility or other Building service and no such failure or
interruption shall entitle Tenant to terminate this Lease or withhold sums due
hereunder, provided that, (a) if any such utilities or services are
interrupted, discontinued or diminished as a result of the negligence or
intentional misconduct of Landlord or its agents, employees, contractors or
invitees such that the Leased Premises are untenantable (meaning that Tenants
business in the Leased Premises for the Permitted Use has been adversely
affected thereby) for more than five (5) consecutive business days, then
Tenant shall notify Landlord in writing that Tenant intends to abate rent, and (b) if
such utilities or services have not been restored within five (5) days of
Landlords receipt of Tenants notice, without extension for force majeure and
without regard to Section 13.03 below, then Base Rent and Additional Rent
shall abate proportionately on a per diem basis for each day during which the
Leased Premises was so untenantable and, if such interruption, diminution,
delay or discontinuance of such utilities or services is material and continues
beyond thirty (30) days, without extension for force majeure and without regard
to the provisions of Section 13.03 below, Tenant shall be entitled to
terminate this Lease at any time thereafter upon notice to Landlord. Landlord
agrees to cooperate reasonably with Tenant to restore any such interrupted,
diminished or discontinued service as soon as reasonably practicable. Tenant
shall obtain in its own name and pay directly to the appropriate supplier the
cost of all janitorial/cleaning services for the Leased Premises.  ARTICLE 7 -

the Leased Premises unless and until Landlord has approved the plans therefor
in writing. As a condition of such approval, Landlord may require Tenant to
remove the alterations and restore the Leased Premises upon termination of this
Lease; otherwise, all such alterations shall become a part of the realty and
the property of Landlord, and shall not be removed by Tenant, unless Tenant, at
its option, removes the same prior to the end of the Lease Term and repairs any
damage caused by such removal, and provided that Tenant shall not be required
to remove any of the Landlords Work. Notwithstanding the foregoing, Landlords

reasonable security to Landlord for and contest the same by appropriate
proceedings within thirty (30) days after notice from Landlord to Tenant of the

amount endorsement waiving coinsurance limitations, subject to commercially

CASUALTY  In the event of total or partial destruction of the Building or the
Leased Premises by fire or other casualty, Landlord agrees promptly to restore
and repair same; provided, however, Landlords obligation hereunder with
respect to the Leased Premises shall be limited to the reconstruction of such
of the leasehold improvements as were originally required to be made by
Landlord pursuant to Section 2.02 above, if any, and the Leased
Premises as otherwise existed prior thereto. Rent shall proportionately abate
during the time that the conduct of Tenants business in the Leased Premises
for the Permitted Use is not reasonably possible and a reasonable period of
time (which in no event shall exceed 14 days) thereafter to allow Tenant to
restore, replace and move in its alterations, additions, improvements,
fixtures, trade fixtures, equipment, furniture and personal property and
prepare for reopening. Notwithstanding the foregoing, if the Leased Premises
are (a) so destroyed that they cannot reasonably be repaired or rebuilt
within one hundred eighty (180) days from the casualty date; (b) destroyed
by a casualty that is not covered by the insurance required hereunder or, if
covered, such insurance proceeds are not released by any mortgagee entitled
thereto, after Landlord makes reasonable efforts, to obtain such release, or
are insufficient (and for such purpose the amount of any deductibles shall be
considered to be released insurance proceeds) to rebuild the Building and the
Leased Premises, or (c) if such damage is substantial and occurs during
the last twelve (12) of the Lease Term; then, in case of a clause (a) casualty,
either Landlord or Tenant may, in the case of a clause (b) casualty, then
Landlord may, or, in the case of a clause (c) casualty, then Tenant may,
upon forty five (45) days written notice to the other party, terminate this
Lease with respect to matters thereafter accruing, such notice to be given no
later than thirty (30) days after such casualty. Tenant waives any right under
applicable laws inconsistent with the terms of this paragraph. If neither party
terminates this Lease pursuant to this Article 9 and the Leased Premises
are not rebuilt within 180 days subject to force majeure not to exceed sixty
(60) days, anything to the contrary contained in Section 16.03
notwithstanding, and Tenant caused delays then, Tenant has the right to
terminate this Lease upon written notice to Landlord, delivered to Landlord
within ten (10) days after the expiration of such 180 day period (as the
same may be so extended). Landlord shall give Tenant reasonable advance notice
of the completion of any repairs and restoration required of it under this Article 9
and Article 10 below.  ARTICLE 10
- EMINENT DOMAIN  If all or any substantial part of the Building or Common Areas shall be
acquired by the exercise of eminent domain, or sale in lieu thereof, Landlord
may terminate this Lease by giving written notice to Tenant at least forty five
(45) days before the date possession thereof is so taken. If all or any part of
the Leased Premises or Project shall be acquired by the exercise of eminent
domain, or sale in lieu thereof, so that the Leased Premises and Common Areas
shall become impractical for Tenant to use for the Permitted Use, Tenant may
terminate this Lease by giving written notice to Landlord no later than and as
of the date possession thereof is so taken. All damages awarded shall belong to
Landlord; provided, however, that Tenant may claim dislocation damages, Tenant
trade fixtures and property, if such amounts are not subtracted from Landlords
award.  If the Lease is not so
terminated, Landlord shall restore that portion of the Leased Premises and the
Project that remains to a whole economic unit with reasonable promptness and
all due diligence. Rent shall abate on an equitable basis for the period such
restoration makes the Leased Premises or a portion thereof untenantable for
Tenants business at the Leased Premises for the Permitted Use, and a
reasonable period of time (not to exceed 14 days) thereafter to allow Tenant to
restore, replace and move in its alterations, additions, improvements,
fixtures, trade fixtures, equipment, furniture and personal property and
prepare for reopening.  ARTICLE 11
- ASSIGNMENT AND SUBLEASE  Section 11.01. Assignment and Sublease.  (a)Tenant shall not assign this Lease or sublet
the Leased Premises in whole or in part without Landlords prior written
consent, which consent shall not be unreasonably withheld, delayed or denied
and, in any event, such consent shall be given or reasonably denied within no
later than fifteen  11


(15)
days after Tenants request for such consent (stating in reasonable detail the
reason or reasons that Landlord is denying its consent to such assignment or
sublease). In the event of any permitted assignment or subletting, Tenant shall
remain primarily liable hereunder. The acceptance of rent from any other person
shall not be deemed to be a waiver of any of the provisions of this Lease or to
be a consent to the assignment of this Lease or the subletting of the Leased
Premises. Any assignment or sublease consented to by Landlord shall not relieve
Tenant (or its assignee) from obtaining Landlords consent to any subsequent
assignment or sublease.  (b)By way of example and not limitation, Landlord shall be deemed to have
reasonably withheld consent to a proposed assignment or sublease if in Landlords
reasonable opinion (i) the Leased Premises are or may be in any way
materially adversely affected; (ii) the business reputation of the proposed
assignee or subtenant is unacceptable; or (iii) the financial worth of the
proposed assignee or subtenant is insufficient to meet the obligations
hereunder, or (iv) the prospective assignee or subtenant is a current
tenant in the Building and is interested in leasing any other space in the
Project available on the market or is a bona-fide third-party prospective
tenant who is then in negotiations with Landlord. Landlord further expressly
reserves the right to refuse to give its consent to any subletting if the
proposed rent is publicly advertised to be less than the then current rent for
similar premises in the Building available on the market. If Landlord refuses
to give its consent to any proposed assignment or subletting, Landlord may, at
its option, within fifteen (15) days after receiving a request to consent,
terminate this Lease as to such proposed subleased or assigned space by giving
Tenant thirty (30) days prior written notice of such termination, whereupon
each party shall be released from all further obligations and liability
hereunder with respect to such space, except those which expressly survive the
termination of this Lease. The foregoing notwithstanding, Tenant may withdraw
its notice of its intention to assign or sublet within ten (10) days after
the giving by Landlord of its notice to terminate the Lease or a portion
thereof, in which case Landlords exercise of its option to terminate the Lease
or a portion thereof shall be null and void and of no force or effect, as if
Tenant had never given its notice of its intention to assign or sublet. If Landlord
exercises its option to terminate the Lease with respect to a portion of the
Leased Premises, Landlord shall pay the cost of erecting any demising walls and
otherwise separating the remaining Premises from that portion of the Leased
Premises for which the Lease has been so cancelled.  (c)If Tenant shall make any assignment or sublease for which Landlords
consent is required, for a rental in excess of the rent payable under this
Lease, Tenant shall pay to Landlord fifty percent (50%) of any such excess
rental within ten (10) days after receipt net of all costs incurred by Tenant
with respect to such assignment or sublease, including, without limitation,
brokerage and attorneys fees and costs and any buildout expenses. Tenant
agrees to pay Landlord $1,000.00 within ten (10) days after demand by
Landlord for reasonable accounting and attorneys fees incurred in conjunction with
the processing and documentation of any requested assignment, subletting or any
other hypothecation of this Lease or Tenants interest in and to the Leased
Premises for which Landlords consent is required as consideration for Landlords
consent.  (d)If requested and commercially reasonable, Landlord shall enter into a
reasonable non- disturbance and attomment agreement with any approved or
permitted sublessee. To the extent requested by Tenant in written notice to
Landlord, Landlord shall provide any assignee of this Lease or any such sublessee
with written notice of any default by Tenant under this Lease, and the
opportunity to cure such default in a timely manner, in the manner provided in Section 13.01
below, and Landlord shall, accept performance by any such assignees or
subtenants as if such performance were rendered by Tenant. To the extent
requested by Tenant in written notice to Landlord, Landlord shall provide
Tenant with written notice of any default by any assignee or sublessee, and the
opportunity to cure such default in a timely manner, in the manner provided in Section 13.01
below, and Landlord shall accept performance by Tenant. Tenant, upon curing
such default, shall be entitled, at its option, at any time thereafter to
regain possession of the Leased Premises.  Section 11.02. Permitted Transfer. Notwithstanding anything to the contrary
contained in Section 11.01 above, Tenant shall have the right,
without Landlords consent and without Landlord having the right to terminate
the Lease as to the proposed subleased or assigned space as provided in Section 11.01
above, but upon ten (10) days prior notice to Landlord, to (a) sublet
all or part of the Leased Premises to any related corporation or other entity
which controls Tenant, is controlled by Tenant or is under common control with
Tenant; (b) assign all or any part of this Lease to any related
corporation or other entity which controls Tenant, is controlled by Tenant, or
is under common control with Tenant, or to a successor entity into which or
with which Tenant is merged or consolidated or which acquires substantially all
of Tenants assets or property; or (c) effectuate any public offering of
Tenants stock on the New York Stock Exchange or in the NASDAQ over the counter
market, provided that in the event of a transfer to a successor pursuant to
clause (b), the tangible net worth of the successor after any such transaction
is not less than the tangible net worth of Tenant as of the date of such
transfer and provided further that such successor entity assumes all of the
obligations and liabilities of Tenant (any such entity described in this clause
(c) or (a) or (b) above hereinafter referred to as a Permitted
Transferee), For the purpose of this Article...11 (i) control
shall mean ownership of not less than fifty percent (50%) of all voting stock
or legal and equitable interest in such corporation or entity, and (ii) tangible
net worth shall mean the excess of the value of tangible assets (i.e. assets
excluding those which are intangible such as  12


goodwill, patents and trademarks) over liabilities. Any such transfer
shall not relieve Tenant of its obligations under this Lease. Nothing in this
paragraph is intended to nor shall permit Tenant to transfer its interest under
this Lease as part of a fraud or subterfuge to intentionally avoid its
obligations under this Lease (for example, transferring its interest to a shell
corporation that subsequently files a bankruptcy), and any such transfer shall
constitute a Default hereunder. Any change in control of Tenant resulting from
a merger, consolidation, or a transfer of partnership or membership interests,
a stock transfer, or any sale of substantially all of the assets of Tenant that
do not meet the requirements of this Section 11.02shall be deemed
an assignment or transfer that requires Landlords prior written consent
pursuant to Section 11.01 above.  ARTICLE 12
- TRANSFERS BY LANDLORD  Section 12.01. Sale of the Building. Landlord shall have the right to sell the
Building at any time during the Lease.Term, subject only to the rights of
Tenant hereunder; and such sale shall operate to release Landlord from
liability hereunder after the date of such conveyance so long as such successor
to Landlord agrees to assume all obligations of Landlord under this Lease
accruing from that point forward. Any funds in the hands of such Landlord or
the then seller, grantor or assignor at the time of such transfer in which
Tenant has an interest, including any Additional Rent or Security Deposit,
shall be turned over to the grantee, and any amount then due and payable to
Tenant by Landlord or the then seller, grantor or assignor under any provisions
of this Lease, shall be paid to Tenant.  Section 12.02. Estoppel Certificate. Within ten (10) days following receipt
of a written request from Landlord, Tenant shall execute and deliver to
Landlord, without cost to Landlord, an estoppel certificate in such form as
Landlord may reasonably request certifying (a) that this Lease is in full
force and effect, if true, and unmodified or stating the nature of any
modification, (b) the date to which rent has been paid, (c) that
there are not, to Tenants knowledge, any uncured defaults or specifying such
defaults if any are claimed, and (d) any other matters or state of facts
reasonably required respecting the Lease. Such estoppel may be relied upon by
Landlord and by any purchaser or mortgagee of the Building.  Section 12.03. Subordination. Landlord shall have the right to subordinate
this Lease to any mortgage, deed to secure debt, deed of trust or other
instrument in the nature thereof, and any amendments or modifications thereto
(collectively, a Mortgage) presently existing or hereafter encumbering the
Building by so declaring in such Mortgage. Within ten (10) days following
receipt of a written request from Landlord, Tenant shall execute and deliver to
Landlord, without cost, any instrument that Landlord deems reasonably necessary
or desirable to confirm the subordination of this Lease. Notwithstanding the
foregoing, if the holder of the Mortgage shall take title to the Leased
Premises through foreclosure or deed in lieu of foreclosure, Tenant shall be
allowed to continue in possession of the Leased Premises as provided for in
this Lease so long as Tenant is not in Default.  ARTICLE 13
- DEFAULT AND REMEDY  Section 13.01. Default. The occurrence of any of the following shall be a Default:  (a)Tenant fails to pay any Monthly Rental Installments or Additional Rent
within five (5) days after written notice thereof from Landlord that the same
is due.  (b)Tenant fails to perform or observe any other term, condition, covenant
or obligation required under this Lease for a period of thirty (30) days after
written notice thereof from Landlord; provided, however, that if the nature of
Tenants default is such that more than thirty (30) days are reasonably
required to cure, then such default shall be deemed to have been cured if
Tenant commences such performance within said thirty (30) day period and thereafter
diligently completes the required action within a reasonable time.  (c)Intentionally omitted.  (d)Tenant shall assign or sublet all or a portion of the Leased Premises
in contravention of the provisions of Article 11 of this Lease.  (e)All or substantially all of Tenants assets in the Leased Premises or
Tenants interest in this Lease are attached or levied under execution (and
Tenant does not discharge the same within sixty (60) days thereafter); a
petition in bankruptcy, insolvency or for reorganization or arrangement is
filed by or against Tenant (and Tenant fails to secure a stay or discharge
thereof within sixty (60) days thereafter); Tenant is insolvent and unable to
pay its debts as they become due; Tenant makes a general assignment for the
benefit of creditors; Tenant takes the benefit of any insolvency action or law;
the appointment of a receiver or trustee in bankruptcy for Tenant or its assets
if such receivership has not been vacated or set aside within thirty (30) days
thereafter; or, dissolution or other termination of Tenants corporate charter
if Tenant is a corporation.  13


In addition to the defaults described above, the parties agree that if
Tenant receives written notice of a violation of the performance of any (but
not necessarily the same) term or condition of this Lease three (3) or
more times during any twelve (12) month period, regardless of whether such
violations are ultimately cured, then such conduct shall, at Landlords option,
represent a separate Default.  Section 13.02. Remedies. Upon the occurrence of any Default, Landlord shall have the following
rights and remedies, in addition to those stated elsewhere in this Lease and
those allowed by law or in equity, any one or more of which may be exercised
without further notice to Tenant:  (a)Landlord may re-enter the Leased Premises and cure any Default of
Tenant, and Tenant shall reimburse Landlord as Additional Rent for any costs
and expenses which Landlord thereby incurs; and Landlord shall not be liable to
Tenant for any loss or damage which Tenant may sustain by reason of Landlords
action.  (b)Without terminating this Lease, Landlord may terminate Tenants right
to possession of the Leased Premises, and thereafter, neither Tenant nor any
person claiming under or through Tenant shall be entitled to possession of the
Leased Premises, and Tenant shall immediately surrender the Leased Premises to
Landlord, and Landlord may re-enter the Leased Premises and dispossess Tenant
and any other occupants of the Leased Premises by any lawful means and may
remove their effects, without prejudice to any other remedy that Landlord may
have. Upon termination of possession, Landlord may (i) re-let all or any part
thereof for a term different from that which would otherwise have constituted
the balance of the Lease Term and for rent and on terms and conditions
different from those contained herein, whereupon Tenant shall be immediately
obligated to pay to Landlord an amount equal to the present value (discounted
at the Prime Rate) of the difference between the rent provided for herein for
the balance of the Lease Term and that provided for in any lease covering a
subsequent re-letting of the Leased Premises, for the period which would otherwise
have constituted the balance of the Lease Term (the Accelerated Rent
Difference), or (ii) from time to time, to recover from Tenant, and
Tenant shall remain liable for, all Base Rent and Additional Rent accruing as
they become due under this Lease during the period from the date of such notice
of termination of possession to the stated end of the Lease Term, less the
amount realized from any reletting of the Premises or any part thereof after
the payment of all Default Damages and Prior Obligations (as defined herein).
Upon termination of possession, Tenant shall be obligated to pay to Landlord (A) the
Accelerated Rent Difference or the amounts under clause (ii) above, (B) all
loss or damage that Landlord may sustain by reason of Tenants Default (Default
Damages), which shall include, without limitation, expenses of preparing the
Leased Premises for re- letting, including demolition, repairs, tenant finish
improvements, brokers commissions and attorneys fees, and (C) all unpaid
Base Rent and Additional Rent that accrued prior to the date of termination of possession,
plus any interest and late fees due hereunder (the Prior Obligations).  (c)Landlord may terminate this Lease and declare the present value
(discounted at the Prime Rate) of all rent which would have been due under this
Lease for the balance of the Lease Term over the then present value (discounted
at the Prime Rate) of the then aggregate fair rental value of the Leased Premises
for the balance of the Lease Term to be immediately due and payable as
liquidated damages (the Accelerated Rent), whereupon Tenant shall be
obligated to pay to Landlord (i) the Accelerated Rent, (ii) all of
Landlords Default Damages, and (iii) all Prior Obligations. It is
expressly agreed and understood that all of Tenants liabilities and
obligations set forth in this subsection (c) shall survive termination.  (d)Landlord and Tenant acknowledge and agree that the payment of the
Accelerated Rent Difference or the Accelerated Rent as set above shall not be deemed
a penalty, but merely shall constitute payment of liquidated damages, it being
understood that actual damages to Landlord are extremely difficult, if not
impossible, to ascertain. Neither the filing of a dispossessory proceeding nor
an eviction of personalty in the Leased Premises shall be deemed to terminate
the Lease.  (e)Landlord may sue for injunctive relief or to recover damages for any
loss resulting from the Default.  Section 13.03. Landlords Default and Tenants Remedies. Landlord shall be in default if it fails to
perform any term, condition, covenant or obligation required under this Lease
for a period of thirty (30) days after written notice thereof from Tenant to
Landlord; provided, however, that if the term, condition, covenant or obligation
to be performed by Landlord is such that it cannot reasonably be performed
within thirty (30) days, such default shall be deemed to have been cured if
Landlord commences such performance within said thirty-day period and
thereafter diligently undertakes to complete the same within a reasonable
period of time. Upon the occurrence of any such default, Tenant may sue for
injunctive relief or to recover damages for any loss directly resulting from
the breach, but Tenant shall not be entitled to terminate this Lease or
withhold, offset or abate any sums due hereunder, except as otherwise herein
provided.  14


Section 13.04. Limitation of Landlords Liability. If Landlord shall fail to perform any term,
condition, covenant or obligation required to be performed by it under this
Lease and if Tenant shall, as a consequence thereof, recover a money judgment
against Landlord, Tenant agrees that it shall look solely to Landlords right,
title and interest in and to the Building and any rents, issues and profits
arising therefrom, or the proceeds arising from any sale or other disposition
thereof for the collection of such judgment; and Tenant further agrees that no
other assets of Landlord shall be subject to levy, execution or other process
for the satisfaction of Tenants judgment.  Section 13.05. Nonwaiver of Defaults. Neither partys failure or delay in
exercising any of its rights or remedies or other provisions of this Lease
shall constitute a waiver thereof or affect its right thereafter to exercise or
enforce such right or remedy or other provision. No waiver of any default shall
be deemed to be a waiver of any other default. Landlords receipt of less than
the full rent due shall not be construed to be other than a payment on account
of rent then due, nor shall any statement on Tenants check or any letter
accompanying Tenants check be deemed an accord and satisfaction. No act or
omission by Landlord or its employees or agents during the Lease Term shall be
deemed an acceptance of a surrender of the Leased Premises, and no agreement to
accept such a surrender shall be valid unless in writing and signed by
Landlord.  Section 13.06. Attorneys Fees. If either party defaults in the performance
or observance of any of the terms, conditions, covenants or obligations
contained in this Lease and the non-defaulting party obtains a judgment against
the defaulting party, then the defaulting party agrees to reimburse the
non-defaulting party for reasonable attorneys fees, court costs and expenses,
incurred in connection therewith. In addition, if a monetary Default shall
occur and Landlord engages outside counsel to exercise its remedies hereunder,
and then Tenant cures such monetary Default, Tenant shall pay to Landlord, on
demand, all expenses incurred by Landlord as a result thereof, including
reasonable attorneys fees, court costs and expenses actually incurred.  Section 13.07. Mitigation of Damages. Anything to the contrary
contained herein notwithstanding, if Tenant breaches this Lease, defaults
and/or if Landlord terminates this Lease or Tenants right to possession,
Landlord shall make reasonable efforts to mitigate Landlords damages and costs
and expenses incurred by Landlord as a result thereof.  ARTICLE 14

the Landlord at the end of the Lease Term.  Section 16.16. Right of First Offer. So long as this Lease is in full force and
effect and free of any Default on the part of Tenant hereunder, and subject to
any now current renewal or expansion rights of existing tenants in the Project,
Tenant shall have the right to lease that portion of the Project that is
contiguous to, but not currently part of the Premises, commonly known as Suite 1858
as depicted on ExhibitA-2
attached hereto (the Option Premises). Except for such renewal or extension
rights of existing tenancies of the Project, Landlord agrees that prior to
entering into any substantial negotiations with any other third party, Landlord
shall as soon as possible first give Tenant written notice that such space is
or will become available. Such notice shall specify the rate of rent, which
will be the then current market rate and the effective date upon which Landlord
is willing to add the Option Premises to the Premises leased by this Lease for
the balance of the Lease Term and any Renewal Term hereof (which date shall be
no later than the date that Landlord in good faith is willing to lease the
Option Premises to third parties). Thereupon Tenant shall have and is hereby
granted the right and option, to be exercised only by written notice given to
Landlord within ten (10) business days after the date of Landlords
notice, to elect to add the Option Premises to the Premises leased by this
Lease at the then current market rate and the effective date specified in
Landlords notice to Tenant and otherwise upon the terms and conditions of this
Lease; and upon timely giving of said notice, the Option Premises shall be so
added to the Premises as of the effective date, provided that the term of the
lease for the Option Premises shall be coterminous with the Lease Term; all
provided, however, that both at the date of Tenants notice and at the
effective date, this Lease is in full force and effect and free of any Default
on the part of Tenant hereunder. In the event that Tenant elects to lease the
Option Premises, and unless included in the market rate, Landlord shall be
under no obligation to construct improvements in the Option Premises and Tenant
agrees that the Option Premises shall be delivered as is. In the absence of
timely notice from Tenant, Landlord shall have the right to lease the Option
Premises to such party or parties upon and subject to such rates, period of
time and other terms and provisions as Landlord shall elect, but Landlord shall
not again be required to offer the Option Premises to Tenant before so leasing
it to others. Notwithstanding anything to the contrary herein, (a) in
order for Tenant to exercise its Right of First Offer pursuant to Section 16.16
during the last two years of the original Lease Term, Tenant must additionally
exercise the Option to Renew as set forth in paragraph 16.17 hereinafter, and (b) the
factors used to determine the market rate for purposes of this Section 16.16
shall be the same as those used to determine Market Rent as provided in Section 16.17
and, if Tenant disagrees with Landlords determination of market rate under
this Section 16.16 and notifies Landlord thereof within such ten (10) business
day period, then Tenant shall be deemed to have exercised such right of first
offer but the market rate shall be determined in accordance with the provisions
of the last paragraph of Section 16.16(b), but the effective date, if
prior to such determination is made, shall be delayed until such determination
is made.  Section 16.17. Option to Renew.  (a)Provided Tenant currently has no uncured Default of any obligation,
covenant or condition of this Lease, Tenant shall have the option to renew the
Lease Term for one additional period of five (5) years following the last
month of the original Lease Term, which will hereinafter be referred to as the Termination
Date (said 5-year period immediately following the Termination Date is the Renewal
Term). The option to renew the Lease for the Renewal Term must be exercised in
a written notice thereof by Tenant which must be delivered to Landlord at least
six (6) months, but not more than nine (9) months (or if the last sentence
of Section 16.16 is operative, two (2) years), prior to the
Termination Date. If the required notice to renew the Lease for the Renewal
Term is not delivered by said 6-month prior date, Tenant will be conclusively
deemed to have waived the option to renew. 
Any reference in the Lease to the Lease Term shall be deemed to
include the Renewal Term and apply thereto, to the extent Tenant has exercised
or exercises its option to extend the Lease for the Renewal Term, unless it is expressly
provided otherwise.  (b)The rent during the Renewal Term shall be equal to the Market Rent (as
defined  18


hereinafter) for the Premises as of the beginning of the Renewal Term.
Written notice of Landlords determination of Market Rent shall be sent to
Tenant within thirty (30) days after Landlords receipt of Tenants notice to
renew for the respective Renewal Term. Unless Tenant sends Landlord a written
notice within fifteen (15) days after Tenants receipt of said determination
withdrawing its exercise of its option to renew or objecting to the
determination, Landlords determination of rent shall be conclusively binding
upon the parties for the Renewal Term. If Tenant does send Landlord such
written withdrawal within said fifteen (15) day period, then Tenant will be
conclusively deemed to have waived the option to renew.  If Tenant delivers to Landlord a written objection to Landlords
determination of the Market Rent within such fifteen (15) day period, then
Landlord and Tenant shall negotiate in good faith to attempt to reach an
agreement on Market Rent, however, if the parties cannot agree on a Market Rent
within another fifteen (15) days after Tenants written objection, then the
Tenant will be conclusively deemed to have waived the option to renew.  (c)Market Rent shall mean the annual rental
rate then being charged by similar projects in the St. Louis metropolitan area
for improved space (not including the improvements made by Tenant) comparable
to the Premises for leases commencing on or about the time of the applicable
renewal period, taking into consideration use and location within the
applicable Project, the location, quality, age and reputation of the Project,
the definition of rentable area or net rentable area, as the case may be, with
respect to which such rental rates are computed, comparative leasehold
improvement, rental concessions and abatements, lease assumptions or
take-overs, moving expenses, the term of the lease under consideration and the
extent of services provided thereunder, applicable distinctions between gross
leases and net leases, base year figures for escalation purposes, other
adjustments (including, by way of example, indexes) to base rental, and any
other relevant term or condition in making such evaluation.  Section 16.18.   Guarantor.  This
Lease is guaranteed by Quixote Corporation per the attached Exhibit F.  Section 16.19. Quiet Enjoyment. Landlord covenants that Tenant, on paying
the rent within any applicable notice and cure periods and on keeping,
observing and performing all the other terms, covenants, conditions, provisions
and agreements herein contained on the part of the Tenant to be kept, observed,
and performed within any applicable notice and cure periods, shall, during the
Lease Term, peaceably and quietly have, hold and enjoy the Leased Premises
subject to the terms, covenants, conditions, provisions, and agreements hereof.  Section 16.20. Joint and Several Liability. If more than one person or entity is named
as Landlord or Tenant herein, the obligations of Landlord or Tenant shall be
the joint and several responsibility of all persons or entities named herein as
Landlord or Tenant, respectively.  [SIGNATURES CONTAINED ON THE FOLLOWING PAGES  19

best interest and Guarantor will be benefited by the lease to Tenant by
Landlord of the Premises (as defined in the Lease), all upon the terms of the
Lease. In order to induce Landlord to enter into the Lease and in consideration
of the benefits to be derived by Guarantor as a result of the Lease with
Tenant, Guarantor is willing to execute and deliver this Guaranty of Lease in
favor of Landlord;  NOW THEREFORE,as a part of the inducement for Landlord to
enter into the Lease with Tenant, Guarantor agrees as follows:  1.In consideration of the execution of the above and foregoing Lease by
Landlord, Guarantor hereby becomes surety for and unconditionally guarantees
the performance of all covenants, conditions, terms, obligations and payments
required of Tenant under the Lease (collectively, the Obligations). If a Default
shall at any time be made by Tenant under the terms of the Lease, Guarantor,
immediately upon demand of Landlord, hereby promises and agrees to pay on the
respective due dates to Landlord all amounts that may be due and to fully
satisfy the conditions and covenants to be paid, kept and performed by Tenant
under the Lease, and to cause the full and faithful performance and observance
of each and all Obligations of the Tenant under and pursuant to the terms and
conditions of the Lease, without relief from valuation or appraisement laws, as
fully and to the same extent as though both Guarantor and Tenant had been named
in the Lease as Tenants therein with joint and several liability. The above
guaranty shall constitute a guaranty of payment and performance.  2.As conditions of liability pursuant to this Guaranty, Guarantor hereby
unconditionally waives (a) any notice of default in the payment of rent or any
other term, covenant or condition of the Lease by Tenant or (b) any
requirement that Landlord exercise or exhaust its rights or remedies against
Tenant or against any person, firm or corporation prior to enforcing its rights
against Guarantor.  3.Landlord may, without notice to Guarantor,
and Guarantor hereby consents thereto, (a) modify or otherwise change or
alter the terms and conditions of the Lease, (b) waive any of its rights
under the Lease or forbear to take steps to enforce any payment or any other
term or condition of the Lease against Tenant.  4.Guarantors obligation to make payment in
accordance with the terms of this Guaranty shall not be impaired, modified,
changed, released or limited in any manner whatsoever by: (i) any
impairment, modification, change, release or limitation of the liability of
Tenant or its estate in bankruptcy resulting from the operation of any present
or future provision of the federal bankruptcy statute or other statute, or from
the decision of any court; (ii) any exercise or nonexercise of or delay in
exercising any right, remedy, power or privilege under or in respect of this
Guaranty or of any agreement related to the Obligations (even if such right,
remedy, power of privilege shall be lost thereby) or any waiver, consent, indulgence
or other action or inaction in respect thereof; (iii) any limitation of
liability of Tenant or Guarantor contained in any agreement related to the
Obligations; (iv) any defense that may arise by reason of Landlords
failure to file or enforce a claim against Tenant or any other surety or
guarantor of the Obligations in any bankruptcy or other proceeding; (v) the

all of the property of Tenant or any other surety or guarantor of the Obligations,
marshaling of assets and liabilities, or other similar proceeding affecting

assets; or (vi) any other circumstances which might otherwise constitute a
legal or equitable discharge of a guarantor or surety other than payment or performance
of the Obligations.  5.This Guaranty shall commence on execution and
delivery of the Lease and continue until all of Tenants obligations under the
Lease are satisfied in full. This Guaranty shall not be diminished by any payment
or performance of the terms, covenants or conditions of the Lease by Guarantor.
If payment of the Obligations or any part thereof is made by Tenant or
Guarantor, the liability of Guarantor hereunder shall continue and remain in
full force and effect.  6.Other than the defense that would be
available to Tenant, Guarantor shall not be entitled to make any defense in any
suit or action instituted by Landlord to enforce this Guaranty or the Lease or
be excused from any liability hereunder, and Guarantor hereby expressly waives
any defense in law or in  1


equity which is not or would
not be available to Tenant, it being the intent hereof that the liability of
Guarantor hereunder is primary and unconditional.  Guarantor further hereby waives, surrenders
and agrees not to claim or enforce, unless or until all of the Obligations with
respect to which Guarantor is liable hereunder have been paid in full or
discharged; (i) any right to be subrogated in whole or in part to any of
Landlords rights or claims against Tenant arising under any agreement related
to the Obligations, and (ii) any right to require the marshaling of any
assets of Tenant, which right of subrogation or marshaling might otherwise
arise from the partial or full payment by Guarantor of its obligations under
this Guaranty.  Guarantor further waives
the benefit of any statute of limitations affecting Guarantors liability under
this Guaranty.  7.In the event
suit or action be brought upon and in connection with the enforcement of this
Guaranty, the non-prevailing party shall pay in addition to any other remedies
provided for in this Guaranty, attorneys fees and all court costs incurred by
the prevailing party.  8.The rights and
obligations created by this Guaranty shall inure to the benefit of and be
binding upon the successors, assigns and legal representatives of Guarantor and
Landlord.  IN WITNESS WHEREOF, Guarantor has executed
