                    D.      Tenant’s
covenant to pay Rent shall be independent of every other covenant in this
Sublease.

                    E.      If
Rent is not paid on the date such payment shall first become due, Tenant shall
pay, relative to the delinquent payment, an amount equal to the sum which would
be payable by Landlord to Prime Landlord for an equivalent default under the
Prime Lease. 

          8.      TENANT’S
OBLIGATIONS. Tenant shall be responsible for, and shall pay for all
maintenance, repairs and replacements to the Premises and its equipment
exclusively serving the Premises reasonable wear and tear excepted, but in no
event shall Tenant be obligated for repairs to the Building’s structure or
systems or the improvements Landlord has made to the Premises unless the damages
(reasonable wear and tear excepted) are caused by Tenant’s acts. 

          9.      QUIET
ENJOYMENT. Landlord represents that it has full power and authority to enter
into this Sublease. So long as Tenant is not in default in the performance of
its covenants and agreements in this Sublease, Tenant’s quiet and peaceable
enjoyment of the Premises shall not be disturbed or interfered with by Landlord,
or by any person claiming by, through, or under Landlord. 

          10.     TENANT’S
INSURANCE. Tenant shall procure and maintain, at its own cost and
expense, the following insurance coverage; (i) commercial general liability
insurance covering bodily injury, property damage and personal and advertising
injury occurring within the Premises or arising out of the use thereof by Tenant
or its agents, employees, officers or invitees, visitors and guests with limits
of not less than $1,000,000 per occurrence and $2,000,000 general aggregate,
$2,000,000 products and completed operations aggregate and $2,000,000 personal
injury and advertising liability aggregate; and (ii) all risk property coverage
or its equivalent form for the full insurable replacement value of all Tenant’s
furniture, equipment, personal property or other removable property or any
Alterations made by Tenant under the provisions of this Sublease, naming
Landlord, as well as Prime Landlord, in the manner required in the Prime Lease.
Tenant shall furnish to Landlord a certificate of Tenant’s insurance required
hereunder not later than ten (10) days prior to Tenant’s taking possession of
the Premises. Each party hereby waives claims against the other for property
damage provided such waiver shall not invalidate the waiving party’s property
insurance and, provided further, that each party obtains from its insurance
carrier a waiver of its right of subrogation. Tenant hereby waives claims
against Prime Landlord and Landlord for property damage to the Premises or its
contents if and to the extent that Landlord waives such claims against Prime
Landlord under the Prime Lease. Tenant agrees to obtain, for the benefit of
Prime Landlord and Landlord, such waivers of subrogation rights from its insurer
as are required of Landlord under the Prime Lease. 

          11.     ASSIGNMENT
  OR SUBLETTING. 

                    A.
Except as provided in Section 11.D. and Section 11.E., without Landlord's and
Prime Landlord’s prior written consent, Tenant shall not (i) assign, 

convey or mortgage this Sublease or any interest under it; (ii)
allow any transfer thereof or any lien upon Tenant’s interest by operation of
law; (iii) further sublet the Premises or any part thereof; or (iv) permit the
occupancy of the Premises or any part thereof by anyone other than Tenant.
Landlord’s consent to an assignment of this Sublease or a further sublease of
the Premises may be withheld in Landlord’s sole and absolute discretion. If
Landlord consents to an assignment or sub-sublease, Landlord shall use
reasonable efforts to obtain the consent of Prime Landlord if such consent is
required to be obtained under the Prime Lease. Any cost of obtaining Prime
Landlord’s consent shall be borne by Tenant.

                    B.      No
permitted assignment shall be effective and no permitted sub-sublease shall
commence unless and until any default by Tenant hereunder shall have been cured.
No permitted assignment or sub-subletting shall relieve Tenant from Tenant’s
obligations and agreements hereunder and Tenant shall continue to be liable as a
principal and not as a guarantor or surety to the same extent as though no
assignment or sub-subletting had been made. 

                    C.      If
Landlord consents to any assignment or sub-sublease and Tenant receives rent or
any other consideration, either initially or during the term of the assignment
or sub-sublease, in excess of the Base Rent and Additional Rent (or, in the case
of a sub-sublease of a portion of the Premises, in excess of the Base Rent paid
by Tenant on a square footage basis under this Sublease), Tenant shall pay to
Landlord fifty (50%) percent of such net excess with the installment of Rent due
immediately following Tenant’s receipt of such net excess. 

                    D.      Notwithstanding
the foregoing provisions of this Section 11, Tenant shall have the right, upon
prior written notice to Landlord, but without Landlord's consent, and provided
Tenant is not then in default, to assign this Sublease, or to sub-sublet the
entire Premises or a portion thereof, to (i) any entity resulting from a merger
or consolidation with Tenant, (ii) any corporation succeeding to all the
business and assets of Tenant, or (iii) any affiliate of Tenant. For purposes
hereof, an affiliate of Tenant is any entity which controls, is controlled by,
or is under common control with Tenant.

                    E.      Notwithstanding
the foregoing provisions of this Section 11 and provided that Tenant is not in
default under the terms of this Sublease, Tenant shall have the right, subject
to Landlord’s consent, such consent not to be unreasonably withheld, conditioned
or delayed, to assign or sub-sublease the entire Premises to an assignee or
sub-subtenant. This right to assign or sub-sublet may be exercised only once,
and any such assignment or sub-sublease shall be subject to the terms of the
Prime Lease.

          12.     
RULES. Tenant agrees to comply with all rules and regulations that Prime
Landlord has made or may hereafter from time to time make for the Building.
Landlord shall not be liable in any way for damage caused by the non-observance
by any of the other tenants of such similar covenants in their leases or of such
rules and regulations. 

          13.      REPAIRS
AND COMPLIANCE. Tenant shall promptly pay for the repairs set forth in
Section 8 hereof and Tenant shall, at Tenant's own expense, comply with
all laws and ordinances, and all orders, rules and regulations of all
governmental authorities and of all insurance bodies and their fire prevention
engineers at any time in force, applicable to the Premises or to Tenant’s
particular use or manner of use thereof, except that Tenant shall not hereby be
under any obligation to comply with any law, ordinance, rule or regulation
requiring any structural alteration of or in connection with the Premises,
unless such alteration is required by reason of Tenant’s particular use or
manner of use of the Premises, or a condition which has been created by or at
the sufferance of Tenant, or is required by reason of a breach of any of
Tenant’s covenants and agreements hereunder. As used herein “structure” or
“structural” shall have the definition ascribed to it in the Prime Lease or if
no specific definition is given therein “structure” or “structural” shall mean
that portion of the Building which is integral to the integrity of the Building
as an existing enclosed unit and shall, in any event, include footings,
foundation, outside walls, skeleton, bearing columns and interior bearing walls,
floor slabs; roof and roofing system. 

          14.      FIRE
OR CASUALTY OR EMINENT DOMAIN. In the event Landlord is entitled, under the
Prime Lease, to a rent abatement as a result of a fire or other casualty or as a
result of a taking under the power of eminent domain, then Landlord shall
equitably adjust the abatement as between Landlord and Tenant, based on the
relative impact of the fire or other casualty, or the taking, as the case may
be. 

          15.      ALTERATIONS.
Tenant shall not make any alterations or additions to the Premises
(“Alterations”) except Cosmetic Alterations, as that term is defined in
the Prime Lease, without Landlord’s (and, if necessary, Prime Landlord's) prior
written consent, but Landlord’s consent to such Alterations shall not be
unreasonably withheld, conditioned or delayed, and if Landlord consents thereto,
Landlord shall use reasonable efforts to obtain the consent of Prime Landlord,
if such consent is required under the Prime Lease. If Alterations by Tenant are
permitted or consented to as aforesaid, Tenant shall comply with all of the
covenants of Landlord contained in the Prime Lease pertaining to the performance
of such Alterations. In addition, Tenant shall indemnify, defend and hold
harmless Landlord against liability, loss, cost, damage, liens and expense
imposed on Landlord arising out of the performance of Alterations by Tenant.
Notwithstanding the foregoing provisions of this Section 15, Tenant, at its sole
cost and expense, shall be allowed to replace the entry door with a glass door
and repaint the Premises. Such glass door and paint color must first be approved
by Landlord, which approval shall not be unreasonable withheld, conditioned or
delayed. The Landlord agrees to waive its right to have the Tenant remove the
entry glass door upon the expiry or termination of this Sublease. 

          16.     
SURRENDER. Upon the expiration of the Term, or upon the termination of
the Sublease or of the Tenant’s right to possession of the Premises, Tenant will
at once surrender and deliver up the Premises, together with all improvements
thereon, to Landlord in good condition and repair, reasonable wear and tear
excepted; conditions existing because of Tenant’s failure to perform
maintenance, repairs or replacements as required of Tenant under this Sublease
shall not be deemed “reasonable wear and tear.”

Said improvements shall include all plumbing, lighting,
electrical, heating, cooling and ventilating fixtures and equipment and other
articles of personal property used in the operation of the Premises (as
distinguished from operations incident to the business of Tenant). Tenant shall
surrender to Landlord all keys to the Premises and make known to Landlord the
explanation of all combination locks which Tenant is permitted to leave on the
Premises. All Alterations in or upon the Premises made by Tenant shall become a
part of and shall remain upon the Premises upon such termination without
compensation, allowance or credit to Tenant; provided, however, that Landlord
shall have the right to require Tenant to remove any Alterations made by Tenant
to the Premises or portion thereof, so long as Landlord so advises Tenant of the
requirement that it remove any Alterations when Landlord approves Tenant’s
Alteration plans. Tenant shall also remove any Alterations made by Tenant, or
portion thereof, which Prime Landlord may require Landlord to remove, pursuant
to the terms of the Prime Lease. In any such event, Tenant shall restore the
Premises to their condition prior to the making of such Alteration, repairing
any damage occasioned by such removal or restoration. If Landlord or Prime
Landlord requires removal of any Alteration made by Tenant, or a portion
thereof, and Tenant does not make such removal in accordance with this Section,
Landlord may, upon prior notice to the Tenant, remove the same (and repair any
damage occasioned thereby), and dispose thereof, or at its election, deliver the
same to any other place of business of Tenant, or warehouse the same. Tenant
shall pay the reasonable costs of such removal, repair, delivery and warehousing
on demand. As between Landlord and Tenant, Tenant shall not be required to
remove any Alterations performed by Landlord prior to the Commencement Date or
to restore the Premises to their condition prior to the making of such
Alterations. If, however, the Term expires at or about the date of the
expiration of the Prime Lease, and if Landlord is required under or pursuant to
the terms of the Prime Lease to remove any Alterations performed prior to the
Commencement Date, Tenant shall permit Landlord to enter the Premises for a
reasonable period of time prior to the expiration of the Sublease for the
purpose of removing its Alterations and restoring the Premises as required with
no cost or expense to Tenant. 

          17.      REMOVAL
OF TENANT’S PROPERTY. Upon expiration of the Term or termination of this
Sublease, Tenant shall remove Tenant’s articles of personal property incident to
Tenant’s business (“Trade Fixtures”); provided, however, that Tenant
shall repair any injury or damage to the Premises which may result from such
removal, and shall restore the Premises to the same condition as prior to the
installation thereof. If Tenant does not remove Tenant’s Trade Fixtures from the
Premises prior to the expiration or earlier termination of the Term, Landlord
may, at its option, remove the same (and repair any damage occasioned thereby
and restore the Premises as aforesaid) and dispose thereof or deliver the same
to any other place of business of Tenant, or warehouse the same, and Tenant
shall pay the reasonable cost of such removal, repair, restoration, delivery or
warehousing to Landlord on demand, or Landlord may treat said Trade Fixtures as
having been conveyed to Landlord with this Sublease as a Bill of Sale, without
further payment or credit by Landlord to Tenant. Provided that no default has
occurred under the terms of this Sublease, upon expiration of the Term, Tenant
may remove and retain the furniture identified in Exhibit B without any further
payment to the Landlord. 

          18.      HOLDING
OVER. Tenant shall have no right to occupy the Premises or any portion
thereof after the expiration of the Term or after termination of this Sublease
or of Tenant’s right to possession upon an Event of Default hereunder. In the
event Tenant or any party claiming by, through or under Tenant holds over,
Landlord may exercise any and all remedies available to it at law or in equity
to recover possession of the Premises, and to recover damages including, without
limitation, damages payable by Landlord to Prime Landlord by reason of such
holdover. For each and every month or partial month that Tenant or any party
claiming by, through or under Tenant remains in occupancy of all or any portion
of the Premises after the expiration of this Sublease or after termination of
this Sublease or Tenant’s right to possession, Tenant shall pay, as minimum
damages and not as a penalty, monthly rental at a rate equal to 150% of the rate
of Base Rent and 100% of Additional Rent payable by Tenant hereunder immediately
prior to the expiration or other termination of this Sublease or of Tenant’s
right to possession. The acceptance by Landlord of any holdover rent shall not
be in satisfaction of Landlord’s damages for such holding over. 

          19.     
ENCUMBERING TITLE. Tenant shall not do any act which shall in any way
encumber the title of Prime Landlord in and to the Building or the Property, nor
shall the interest or estate of Prime Landlord or Landlord be in any way subject
to any claim by way of lien or encumbrance, whether by operation of law by
virtue of any express or implied contract by Tenant, or by reason of any other
act or omission of Tenant. Any claim to, or lien upon, the Premises, the
Building or the Property arising from any act or omission of Tenant shall accrue
only against the leasehold estate of Tenant and shall be subject and subordinate
to the paramount title and rights of Prime Landlord in and to the Building and
the Property and the interest of Landlord in the premises leased pursuant to the
Prime Lease. Without limiting the generality of the foregoing, Tenant shall not
permit the Premises, the Building or the Property to become subject to any
mechanics’, laborers’ or materialmen’s lien on account of labor or material
furnished to Tenant or claimed to have been furnished to Tenant in connection
with work of any character performed or claimed to have been performed on the
Premises by, or at the direction or sufferance of, Tenant; provided, however,
that if so permitted under the Prime Lease, Tenant shall have the right to
contest in good faith and with reasonable diligence, the validity of any such
lien or claimed lien if Tenant shall give to Prime Landlord and Landlord such
security as may be deemed satisfactory to them to assure payment thereof and to
prevent any sale, foreclosure, or forfeiture of the Premises, the Building or
the Property by reason of non-payment thereof; provided further, however, that
on final determination of the lien or claim of lien, Tenant shall immediately
pay any judgment rendered, with all proper costs and charges, and shall have the
lien released and any judgment satisfied. 

          20.      INDEMNITY.
Tenant agrees to indemnify Landlord and hold Landlord harmless from all
losses, damages, liabilities and expenses which Landlord may incur, or for which
Landlord may be liable to Prime Landlord, arising from the acts or omissions of
Tenant which are the subject matter of any indemnity or hold harmless of
Landlord to Prime Landlord under the Prime Lease. 

          21.      LANDLORD’S
RESERVED RIGHTS. Landlord reserves the right, on reasonable prior notice, to
inspect the Premises, or to exhibit the Premises to persons having a legitimate
interest at any time during the Term. 

          22.      DEFAULTS.
Tenant further agrees that any one or more of the following events shall be
considered Events of Default as said term is used herein, that is to say, if:

                    A.      Tenant
shall be adjudged an involuntary bankrupt, or a decree or order approving, as
properly filed, a petition or answer filed against Tenant asking reorganization
of Tenant under the Federal bankruptcy laws as now or hereafter amended, or
under the laws of any State, shall be entered, and any such decree or judgment
or order shall not have been vacated or stayed or set aside within sixty (60)
days from the date of the entry or granting thereof; or 

                    B.     
Tenant shall file, or admit the jurisdiction of the court and the material
allegations contained in, any petition in bankruptcy, or any petition pursuant
or purporting to be pursuant to the Federal bankruptcy laws now or hereafter
amended, or Tenant shall institute any proceedings for relief of Tenant under
any bankruptcy or insolvency laws or any laws relating to the relief of debtors,
readjustment of indebtedness, reorganization, arrangements, composition or
extension; or 

                    C.      Tenant
shall make any assignment for the benefit of creditors or shall apply for or
consent to the appointment of a receiver for Tenant or any of the property of
Tenant; or 

                    D.      Tenant
shall admit in writing its inability to pay its debts as they become due; or

                    E.      The
Premises are levied on by any revenue officer or similar officer; or 

                    F.      A
decree or order appointing a receiver of the property of Tenant shall be made
and such decree or order shall not have been vacated, stayed or set aside within
sixty (60) days from the date of entry or granting thereof; or 

                    G.      Tenant
shall abandon the Premises during the Term hereof and fail to pay Rent; or 

                    H.     
Tenant shall fail to make any payment of Rent required to be made by Tenant
hereunder when due as herein provided and such failure shall continue for five
(5) days after notice thereof in writing to Tenant; provided, however, that
Tenant shall be entitled to only one (1) such notice during each twelve (12)
month period of the Term; or 

                    I.      Tenant
shall fail to secure insurance or to provide evidence of insurance as set forth
in Section 10 of this Sublease or shall default with respect to lien 

claims as set forth in Section 19 of this Sublease and
either such default shall continue for five (5) days after notice thereof in
writing to Tenant; or 

                    J.      Tenant
shall, by its act or omission to act, cause a default under the Prime Lease and
such default shall not be cured within the time, if any permitted for such cure
under the Prime Lease; or 

                    K.      Tenant
shall default in any of the other covenants and agreements herein contained to
be kept, observed and performed by Tenant, and such default shall continue for
thirty (30) days after notice thereof in writing to Tenant. 

          23.      REMEDIES.
Upon the occurrence of any one or more Events of Default, Landlord may
exercise any remedy against Tenant which Prime Landlord may exercise for default
by Landlord under the Prime Lease. 

          24.      SECURITY
DEPOSIT.

                    
A.      To secure the faithful performance by
Tenant of all the covenants, conditions and agreements in this Sublease set
forth and contained on the part of Tenant to be fulfilled, kept, observed and
performed including, but not by way of limitation, such covenants and agreements
in this Sublease which become applicable upon the termination of the same by
re-entry or otherwise, Tenant has deposited with Landlord the Security Deposit
as specified in Section 1(L) on the understanding that: (a) the Security Deposit
or any portion thereof not previously applied, or from time to time, such one or
more portions thereof, may be applied to the curing of any default that may then
exist, without prejudice to any other remedy or remedies which Landlord may have
on account thereof, and upon such application Tenant shall pay Landlord on
demand the amount so applied which shall be added to the Security Deposit so the
same may be restored to its original amount; (b) should the Prime Lease be
assigned by Landlord, the Security Deposit or any portion thereof not previously
applied may be turned over to Landlord’s assignee and if the same be turned over
as aforesaid, Tenant hereby releases Landlord from any and all liability with
respect to the Security Deposit and/or its application or return; (c) Landlord
or its successor shall not be obligated to hold the Security Deposit as a
separate fund, but on the contrary may commingle the same with its other funds;
(d) if Tenant shall faithfully fulfill, keep, perform and observe all of the
covenants, conditions and agreements set forth and contained in this Sublease to
be fulfilled, kept, performed and observed on the part of Tenant, the sum
deposited or the portion thereof not previously applied, shall be returned to
Tenant without interest no later than thirty (30) days after the expiration of
the Term or any renewal or extension thereof, provided Tenant has vacated the
Premises and surrendered possession thereof to Landlord at the expiration of the
Term or any renewal or extension thereof as provided herein; (e) if Landlord
terminates this Sublease or Tenant’s right to possession by reason of an Event
of Default by Tenant, Landlord may apply the Security Deposit against damages
suffered to the date of such termination and/or may retain the Security Deposit
to apply against such damages as may be suffered or shall accrue thereafter by
reason of Tenant’s default; and (f) in the event any bankruptcy, insolvency,
reorganization or other creditor-debtor proceedings shall be instituted by or
against Tenant, or its successors or assigns, the 

Security Deposit shall be deemed to be applied first to the
payment of any Rent due Landlord for all periods prior to the institution of
such proceedings, and the balance, if any, of the Security Deposit may be
retained or paid to Landlord in partial liquidation of Landlord’s damages. 

                    B.      The
provisions of Section 24.A notwithstanding, in lieu of a cash Security Deposit,
Tenant shall have the right to deliver to Landlord a letter of credit in the
amount of $16,176.00. The issuer and the form of the letter of credit and the
conditions for drawing upon the letter of credit shall be subject to the
approval of Landlord; provided, however, that such approval shall not be
unreasonably withheld or conditioned. 

          25.     
NOTICES AND CONSENTS. All notices, demands, requests, consents or
approvals which may or are required to be given by either party to the other
shall be in writing and shall be deemed given when received or refused if sent
by United States registered or certified mail, postage prepaid, return receipt
requested or if sent by overnight commercial courier service (a) if to Tenant,
addressed to Tenant at the address specified in Section l(B) or at such other
place as Tenant may from time to time designate by notice in writing to
Landlord; or (b) if for Landlord, addressed to Landlord at the address specified
in Section 1(C) or at such other place as Landlord may from time to time
designate by notice in writing to Tenant. Each party agrees promptly to
deliver a copy of each notice, demand, request, consent or approval from such
party to Prime Landlord and promptly to deliver to the other party a copy of any
notice, demand, request, consent or approval received from Prime Landlord. Such
copies shall be delivered by overnight commercial courier. Tenant may rely upon
any notice, consent or approval given in writing by Landlord’s agent or
attorney. 

          26.     
PROVISIONS REGARDING PRIME LEASE. This Sublease and all the rights of
parties hereunder are subject and subordinate to the Prime Lease. Each party
agrees that it will not, by its act or omission to act, cause a default under
the Prime Lease. In furtherance of the foregoing, the parties hereby confirm,
each to the other, that it is not practical in this Sublease agreement to
enumerate all of the rights and obligations of the various parties under the
Prime Lease and specifically to allocate those rights and obligations in this
Sublease. Accordingly, in order to afford to Tenant the benefits of this
Sublease and of those provisions of the Prime Lease which by their nature are
intended to benefit the party in possession of the Premises, and in order to
protect Landlord against a default by Tenant which might cause a default or
event of default by Landlord under the Prime Lease: 

                    A.     
Provided Tenant shall timely pay all Rent when and as due under this Sublease,
Landlord shall pay, when and as due, all base rent, additional rent and other
charges payable by Landlord to Prime Landlord under the Prime Lease; 

                    B.     
Landlord shall perform its covenants and obligations under the Prime Lease which
do not require for their performance possession of the Premises and which are
not otherwise to be performed hereunder by Tenant on behalf of Landlord. For
example, Landlord shall at all times keep in full force and effect all insurance
required of Landlord as tenant under the Prime Lease. 

                    C.      Tenant
shall perform all affirmative covenants and shall refrain from performing any
act which is prohibited by the negative covenants of the Prime Lease, where the
obligation to perform or refrain from performing is by its nature imposed upon
the party in possession of the Premises. If practicable, Tenant shall perform
affirmative covenants which are also covenants of Landlord under the Prime Lease
(other than the obligation to pay Rent) at least five (5) days prior to the date
when Landlord’s performance is required under the Prime Lease. Landlord shall
have the right to enter the Premises to cure any default by Tenant under this
Section. 

                    D.      Landlord
hereby grants to Tenant the right to receive all of the services and benefits
with respect to the Premises which are to be provided by Prime Landlord under
the Prime Lease including, without any limitation of the foregoing, the
non-exclusive use of the Common Facilities. Landlord shall have no duty to
perform any obligations of Prime Landlord which are, by their nature, the
obligation of an owner or manager of real property. For example, Landlord shall
not be required to provide the services or repairs which the Prime Landlord is
required to provide under the Prime Lease. Landlord shall have no responsibility
for or be liable to Tenant for any default, failure or delay on the part of
Prime Landlord in the performance or observance by Prime Landlord of any of its
obligations under the Prime Lease unless same are as a result of negligence or
willful conduct of the Landlord, nor shall such default by Prime Landlord affect
this Sublease or waive or defer the performance of any of Tenant’s obligations
hereunder except to the extent that such default by Prime Landlord excuses
performance by Landlord under the Prime Lease. The preceding sentence
notwithstanding, Landlord shall use commercially reasonable efforts to cause
Prime Landlord to honor its obligations under the Prime Lease.

          27.      ADDITIONAL
SERVICES. Landlord shall cooperate with Tenant to cause Prime Landlord to
provide services required by Tenant in addition to those otherwise required to
be provided by Prime Landlord under the Prime Lease. Tenant shall pay Prime
Landlord’s charge for such services promptly after having been billed therefor
by Prime Landlord or by Landlord. If at any time a charge for such additional
services is attributable to the use of such services both by Landlord and by
Tenant, the cost thereof shall be equitably divided between Landlord and Tenant.

          28.      PRIME
LANDLORD. Landlord and Tenant hereby agree, for the benefit of Prime
Landlord, that this Sublease shall not (a) create privity of contract between
Prime Landlord and Tenant; (b) be deemed to have amended the Prime Lease in any
regard; or (c) be construed as a waiver of Prime Landlord’s right to consent to
any assignment of the Prime Lease by Landlord or any further subletting of
premises leased pursuant to the Prime Lease, or as a waiver of Prime Landlord’s
right to consent to any assignment by Tenant of this Sublease or any sub-letting
of the Premises or any part thereof.

          29.      BROKERAGE.
Each party warrants to the other that it has had no dealings with any broker
or agent in connection with this Sublease other than the Brokers specified in
Sections 1M and 1N, whose commissions shall be paid by Landlord. Each 

party covenants to pay, hold harmless and indemnify the other
party from and against any and all costs (including reasonable attorneys’ fees),
expense or liability for any compensation, commissions and charges claimed by
any other broker or other agent with respect to this Sublease or the negotiation
thereof on behalf of such party. 

          30.      FORCE
MAJEURE. Neither Landlord nor Tenant shall be deemed in default with respect
to any of the terms, covenants and conditions of this Sublease (other than the
payment of money), if such party's failure to timely perform is due in whole or
in part to any strike, lockout, labor trouble (whether legal or illegal), civil
disorder, failure of power, restrictive governmental laws and regulations,
riots, insurrections, war, shortages, accidents, casualties, acts of God, delays
caused directly by the other party or its agents, employees and invitees, or any
other cause beyond the reasonable control of such party. 

          31.      ADDITIONAL
PROVISIONS.

                    A.      Commencing
from the Commencement Date and throughout the Term, Tenant shall be entitled to
utilize up to thirteen (13) unreserved parking spaces on level P-3 of the
Parking Facilities. Tenant will initially utilize eight (8) such parking spaces.
Tenant may increase the number of parking spaces utilized, up to a maximum of 13
spaces, effective as of each anniversary of the Commencement Date, by delivering
notice thereof to Landlord not later than November 1st of each year
during the Term. The terms shall be the same as those applicable to Landlord's
use of such parking spaces and Tenant shall pay Landlord the amount that
Landlord is charged for the parking spaces by Prime Landlord from time to time
($65.56 per space per month as of the date hereof). 

                    B.     
Landlord shall permit Tenant to enter the Premises to install the front door
alterations, Tenant's furniture, telecommunications and computer systems, and
voice/data cabling, to paint, and for similar pre-occupancy purposes. Such right
of entry shall apply for the two-week period preceding the Commencement Date and
shall be subject to a mutually agreed-upon schedule, both parties acting
reasonably. Tenant's entry to the Premises during such period shall be subject
to all the terms and conditions of this Sublease, except the obligation to pay
Base Rent. 

                    C.     
Landlord agrees to work with Prime Landlord to secure the approval of Prime
Landlord to the installation of signage at the entry of Tenant’s suite, and to
request two (2) listings, in Tenant’s name, in the Building directory. Tenant
agrees to pay the costs for such signage and acknowledges that all such signage
must be approved by Prime Landlord.

                    D.     
Subject to Landlord’s right of recapture as described in this subparagraph
31(D), Tenant shall have the right to renew this Sublease for one year under the
same terms and conditions, except that Base Rent for such additional year shall
increase by four percent (4%) as set forth in Section 1(J). Tenant shall provide
Landlord with written notice of its intent to renew the Sublease no later than
July 1, 2007. If Landlord intends to recapture the Premises on the Expiration
Date, Landlord shall provide written notice to Tenant of its intent to recapture
the Premises no later than 

August 1, 2007. If Landlord exercises this right of recapture
in accordance with the foregoing, the Sublease shall terminate on the Expiration
Date. If Landlord does not exercise its right of recapture, the Term shall be
extended until November 30, 2008. 

                    E.      If
the Landlord fails to perform any term, covenant, provision or condition of this
Sublease to be performed or observed by the Landlord, the Tenant shall have the
same rights and remedies as the Landlord is provided under Sections 53(a) &
(b) of the Prime Lease with respect to such failure to perform by the
Landlord.

                    The
parties have executed this Sublease the day and year first above written.
