                                WITNESSETH THAT:

         In consideration of the mutual covenants, promises and agreements
herein contained, Landlord hereby lets and demises to Tenant, and Tenant hereby
leases from Landlord all those certain premises comprising Building No. 2 (the
"Building"), in the Jackson Square Office Park (the "Office Park"), as the
Building and Office Park are shown on a layout plan attached hereto as Exhibit
"A," and known as 4701 Carr Drive, Fredericksburg, Spotsylvania County, Virginia
22408, containing approximately 10,000.00 square feet (the "Premises").

THE PARTIES DO HEREBY AGREE AND COVENANT AS FOLLOWS:

1. COMMENCEMENT DATE/LEASE TERM/EXTENSION/OCCUPANCY.

         A. The date on which the latter of Landlord or Tenant shall ratify this
Lease shall be the Commencement Date. The Premises are accepted by Tenant in an
"as is" condition.

         B. The Lease shall commence on the Commencement Date and run until
midnight October 31, 2009 (the "Lease Term"). Notwithstanding the aforesaid,
Tenant shall have the rights set forth in Paragraph 42 hereof.

         C. Provided Tenant is not in default at the time of exercise, Tenant
shall have the right to enter into an extension of the Lease for an additional
three (3) year term at a mutually acceptable rental rate; provided, however, in
no event shall the rental rate for any extension period be less than the rental
rate paid in the last year of the original Lease. The extension option shall be
exercised by Notice to Landlord given a minimum of ninety (90) days prior to the
expiration of the original Lease Term.

         D. Tenant may not enter or occupy the Premises prior to the
Commencement Date without Landlord's express written consent. Occupancy of the

3. BASE RENT ESCALATION. Commencing on the first day of November, 2005, and on
the first day of each November thereafter during the Lease Term (each of such
dates being herein referred to as an "Adjustment Date"), the Base Rent in effect
immediately preceding the Adjustment Date shall be increased by an amount equal
to the product of the Base Rent in effect immediately proceeding the Adjustment
Date then at hand (which Base Rent shall be annualized if the year in which the
Commencement Date occurs is a partial year, and which Base Rent shall not
reflect any rental abatement or deferral) multiplied by four percent (4%). Such
computation shall constitute the Base Rent, as adjusted, payable in equal
monthly installments, commencing on the Adjustment Date then at hand and
continuing on the first day of each month thereafter until the next Adjustment
Date or the end of the Lease Term, whichever is applicable.

4. MAINTENANCE/OPERATING EXPENSES/UTILITIES/TAXES. Tenant shall be responsible
for all maintenance and repairs to the interior of the Premises. The HVAC,
plumbing and electric systems of the Premises shall be maintained by the Tenant
with qualified and licensed contractors. Repairs or replacement of major system
components of the existing HVAC, plumbing or electric system shall be the
responsibility of the Tenant up to a maximum expense of Three Thousand and
00/100 Dollars ($3,000.00) annually. The Landlord shall be responsible for the
cost of repairs or major component replacement which exceeds $3,000.00 annually,
and in such event, Landlord may elect to coordinate and contract for such work.
Should Landlord not elect to contract for such work, Tenant shall request the
Landlord's written approval to incur costs for such repairs, which shall not be
unreasonably withheld. The Tenant shall submit documentation of incurred repair
costs for reimbursement by the Landlord. Reimbursement by the Landlord to the
Tenant for previously approved repair costs beyond the $3,000.00 shall be made
within thirty (30) days of written request therefore.

         Tenant shall be responsible for all janitorial services with respect to
the interior of the Premises, including such routine matters as light bulb

services, with the scope of work for such supplier to be consistent with
janitorial services typically supplied to office tenants. Tenant shall keep the
Premises neat, clean and sanitary and shall not itself and shall not permit any
person to destroy, deface, damage, impair or remove any part of Premises or the
facilities or appurtenances thereto.

         Tenant, at its sole cost and expense, shall arrange for and pay all
charges when due for water, gas, electricity, heat, cable and any other utility
services provided to, used by or consumed on the Premises. Tenant hereby
covenants and agrees to indemnify and save Landlord harmless from and against
any and all claims, losses and expenses arising from the installation and
maintenance of such utility services and from all costs for any and all utility
services provided to, used by or consumed on the Premises. Tenant shall pay its

          Landlord shall be responsible for maintenance and repairs to the roof,
foundation, all structural components and the exterior of the Building and the
common areas of the Building and Office Park. Landlord shall be responsible for
the payment of operating expenses, taxes and the insurance to be maintained by
Landlord (as distinguished from insurance to be maintained by Tenant, which
Tenant insurance shall be paid for by Tenant).

5. PAYMENT/ADDITIONAL RENT. All sums of money or charges required to be paid by
Tenant under this Lease other than Base Rent shall be deemed Additional Rent
hereunder and all remedies applicable to the non-payment of Base Rent shall be
applicable thereto. Additional Rent shall accrue commencing on the Commencement
Date Hereof. All Base Rent and Additional Rent (collectively "Rent") shall be
paid without prior notice or demand therefor as to Base Rent and within ten (10)
days of written notice as to Additional Rent (unless tenant has previously been
given a schedule of Additional Rent and due dates therefore, in which case no
notice will be required therefore), and without any counter-claim, set-off,
deduction, recoupment, credit or defense whatsoever, it being understood and
agreed that Tenant's covenant to pay the Rent is hereby deemed to be, and shall
be, independent of the obligations of Landlord hereunder. All payments shall be
applied to the earliest amount then due. No receipt and/or acceptance by
Landlord of any sums shall be deemed a waiver of any default by Tenant, with the
exception of the default identified in Paragraph 19E below, which may be cured
by payment of all Rent and Additional Rent that is currently then due. Landlord
shall have the right to require Rent payments to be made by money order, by
cashier's check or certified check. A late charge in the amount of five percent
(5 %) of any overdue amount shall be immediately due and owing by Tenant to
Landlord as Additional Rent for any payment delinquent seven (7) days after the
due date. Payment of the Rent and Additional Rent (including the 5 % late
charge) within fifteen 15 days of the original due date shall cure such default.

6. TENANT'S POSSESSION. Tenant's right of possession shall commence on the
Commencement Date.

7. SECURITY DEPOSIT. Upon execution of this Lease by Tenant, Tenant shall
deposit with Landlord the sum of Twelve Thousand Five Hundred and 00/100 Dollars
($12,500.00), to be held by Landlord as a security deposit ("Security Deposit"),

provision, covenant and condition of this Lease. The Security Deposit or any
portion not so used, applied or retained shall be refunded to Tenant after
termination of the tenancy and delivery of possession of the Premises to
Landlord. Tenant shall not utilize the Security Deposit as rent. If any part of
the Security Deposit shall have been utilized by Landlord in accordance with the
terms hereof or applicable law, Tenant shall immediately deposit with Landlord a
sum equal to the amount so applied by Landlord so Landlord shall have the full
Security Deposit on hand at all times during the Term.

to any property or injury to, or death of, any person in, upon, or about the
Premises, arising at any time and from any cause other than by reason of the
gross negligence or willful misconduct of Landlord, its agents, employees,
representatives, or contractors. Tenant shall, and hereby agrees to, indemnify
and hold Landlord harmless from any loss, cost, claim, expense and the like,
including damage to any property or injury to, or death of, any person relating
to the Premises or Tenant's failure to comply with the terms of this Lease
unless such damage is caused by the gross negligence or willful misconduct of
Landlord.

withheld, conditioned or delayed. Landlord makes no express or implied
representation or warranty to Tenant with respect to the composition of the
other tenants in the Office Park.

         B. Tenant's suite entry signage and Building signage, if any, shall be
provided by the Tenant at Tenant's expense, the exact location to be mutually

required by any governmental authority to make repairs, alterations or additions

liens arising in connection with the construction of the Improvements to be
performed by Landlord.

15. USES/EXCLUSIVITY. The Premises will be used solely for business office
purposes and for no other purpose without Landlord's consent, which consent will
not be unreasonably withheld if such additional use is consistent with the

the Office Park, does not compete with any other use in the Office Park or
violate any other exclusive granted any other tenant in the Office Park. If any
governmental licenses or permits shall be required for the proper and lawful

in effect at all times during the Term, policies providing for primary insurance
coverage of the following types: Property Insurance (excluding the exterior and
structural components and common areas of the Building) and Liability Insurance
covering Tenant's activities in the Premises and common areas of the Building
and Office Park, and Tenant's Worker's Compensation Insurance. Tenant's
liability insurance shall be in the minimum amount of One Million Dollars
($1,000,000), combined single limit, written on an occurrence basis. All

requirements regarding scope of coverage, limits of coverage, terms and
conditions of coverage, qualification of carriers, named insureds, notice of
cancellation provisions and waiver of subrogation rights.

         B. Neither the issuance of any insurance policy required hereunder, nor
the minimum limits established by Landlord with respect to Tenant's insurance
coverage, shall be deemed to limit or restrict in any way Tenant's liability
arising under or out of this Lease. Tenant shall deliver to Landlord a duplicate
original or certified copy of each insurance policy required by Landlord,
together with evidence of payment of all applicable premiums. Tenant's insurance
shall specifically provide that unless Landlord has been given thirty (30) days'
prior written notice, such insurance policy shall not be canceled and shall
remain in full force and effect. Tenant shall not do or permit to be done any
act or thing in or upon the Premises which shall increase the rate or rates of
any insurance referred to hereinabove. If by reason of failure of Tenant to
comply with this provision, the rate or rates of any insurance coverage referred
to above shall at any time be higher than it otherwise would be, and if Landlord
is required to or has elected to obtain and maintain any such insurance
coverage, then Tenant shall reimburse Landlord on demand as Additional Rent for
such increased premium(s).

         C. Insurance covering the exterior and structural components of the
Building and the common areas of the Building and Office Park shall be obtained
by Landlord, which insurance shall be in the amount of the replacement value of
such items.

20. REMEDIES. Should a Default occur under this Lease, Landlord may pursue the
following:

         A. Landlord shall have the right, by written notice to Tenant, to
declare this Lease terminated and the Lease Term ended and retain or receive the
Security Deposit (as defined herein), in which event (i) Tenant shall vacate and
surrender the Premises; (ii) Tenant shall immediately pay to Landlord the sum of
(aa) all rent accrued through the date of termination or recovery of possession
by Landlord, whichever is later (including any deferred or abated rent) ; plus
(bb) the actual loss suffered by Landlord. The failure of Landlord to relet the
Premises shall not affect Tenant's liability; provided, however, Landlord agrees
to use good faith efforts to relet the Premises upon such terms and conditions
as Landlord may determine advisable in its sole discretion. All rentals and
other sums received by Landlord from reletting shall be applied, first, to the
payment of any related costs and expenses; second, to the payment of any
indebtedness other than rent due hereunder from Tenant to Landlord; third, to
the payment of rent due and unpaid hereunder; and the residue, if any, shall be
applied as a credit against the actual loss suffered by Landlord. If such
rentals and other sums are less than the amounts due pursuant to the foregoing
schedule for application of proceeds, Tenant shall be liable for such
deficiency; if such rentals and other sums shall be more, Tenant shall have no
right to, and shall receive no credit for, the excess.

         B. Landlord shall have the right to bring a special proceeding to
recover possession of the Premises from Tenant.

         C. Landlord shall have the right, without notice (except notice of
default as required by Paragraph 19.I), to re-enter the Premises and dispossess,
by any lawful means, Tenant and any other occupant(s) of the Premises, and
Tenant shall have no further claim or right hereunder. The words "re-enter" and
"re-entry" as used herein shall not be restricted to their technical legal
meaning.

         D. Landlord may exercise its rights under Paragraph 20B or C above with
or without terminating the Lease, and in no event shall any such exercise be
construed as an election to terminate this Lease or operate to release Tenant
from any of its obligations for the remainder of the Lease Term, or give rise to
any claim for trespass.

                                       8

<PAGE>

         E. If Landlord exercises its rights under Paragraph 20B or C above and
elects NOT to terminate the Lease, it may from time to time, make such
alterations and repairs as necessary in order to relet the Premises, and
thereafter relet the Premises or any part thereof for such rent and upon such
terms and conditions as landlord may determine advisable in its sole discretion.
All rents and other sums received by Landlord from reletting shall be applied,
first, to the payment of any related costs and expenses; second, to the payment
of any indebtedness other than Rent due hereunder from Tenant to Landlord;
third; to the payment of Rent due and unpaid hereunder; and the residue, if any,
shall be applied in payment of the current month's Rent. If such rents and other
sums are less than the amounts due pursuant to the foregoing schedule for
application of proceeds, tenant shall pay such deficiency to landlord monthly;
if such rents and other sums shall be more, Tenant shall have no right to, and
shall receive no credit for the excess.

         F. Any damage or loss of rent sustained by Landlord may be recovered at
the time of the reletting or termination, in a single action or in separate
actions, from time to time, as said loss of rents or damages shall accrue, or in
a single proceeding deferred until the expiration of the Lease Term (in which
event Tenant hereby agrees that the cause of action shall not be deemed to have
accrued until the date of expiration of said Lease Term).

         G. To the extent permitted by law, Tenant waives notice of re-entry or
institution of legal proceedings. The foregoing shall not constitute a waiver by
Tenant of any notice of default due in accordance with Paragraph 19.

         H. In addition to the other remedies provided in this Lease, and
anything contained herein to the contrary notwithstanding, Landlord shall (i) be
entitled to restraint by injunction of any violation of this Lease, and (ii)
have a right of distraint for rent and a lien on all of Tenant's furniture,
trade fixtures and equipment in the Premises, as security for rent.

         I. Tenant and Landlord each hereby waive all right to trial by jury in
any matter arising out of or in any way connected with this Lease.

         J. Landlord shall have the right, at its option, to immediately and
without notice cure a default by Tenant for the account and at the expense of
Tenant and to utilize the Security Deposit for such purposes. Tenant agrees to
pay, with interest at twelve percent (12%) per annum on demand, to Landlord the
amount so incurred by Landlord in connection with such default.

         K. With respect to the rights and remedies and waivers herein, (i) such
rights and remedies shall be in addition to any other right and remedy now or
hereafter available at law or in equity; (ii) all such rights and remedies shall
be cumulative and not exclusive of each other; (iii) such rights and remedies
may be exercised at such times, in such order, to such extent, and multiple
times without regard to whether the exercise of one right or remedy precedes,
concurs with or succeeds the exercise of another; and (iv) no waiver of a
Default shall be effective unless acknowledged in writing signed by Landlord.

21. SURRENDER.

         A. Tenant will, upon termination of this Lease, surrender the Premises
and all fixtures and equipment of Landlord therein in good, clean and operating
condition, in the same condition as when received, ordinary wear and tear
excepted. Tenant shall deliver all keys to the Premises to Landlord within
twenty-four hours after vacating.

         B. All leasehold improvements (including the Improvements, if any),
alterations and other physical additions made to the Premises (excluding
Tenant's furniture), whether by Tenant or Landlord, shall be Landlord's property
and shall not be removed from the Premises. Notwithstanding the foregoing, upon
the expiration or earlier termination of this Lease, Tenant shall, at Tenant's
expense, remove any of the foregoing items (excluding the Improvements, if any)
from the Premises if Landlord gives Tenant written notice to do so. Tenant shall
promptly repair or reimburse Landlord for the cost of repairing all damage done
to the Premises by such removal.

22. HOLDING OVER. If Tenant shall hold possession of the Premises after the
expiration or sooner termination of the Term, Tenant shall be deemed a
month-to-month tenant at a rate equal to the rate in effect at the time of such
termination if, but only if, Landlord and Tenant agree to such continued
occupancy pursuant to a written agreement. In the absence of a written
agreement, at Landlord's election (a) Tenant shall be treated as a trespasser,
and Landlord shall be entitled to the benefit of all laws relating to the speedy
recovery of the possession of the Premises; or (b) such continued occupancy
shall be deemed a month to-month tenancy subject to the terms of the Lease and
holdover rent shall accrue at a rate equal to twice the sum of (i) the monthly
installment of Base Rent payable during the last month of the Term, and (ii)
one-twelfth (1/12) of the monthly installments of Additional Rent payable during
the last month of the Term.

23. DESTRUCTION. If the Premises shall be damaged or destroyed by fire or other
casualty not resulting from the negligence of Tenant or Tenant's employees,
agents or invitees, and as a result thereof shall be untenantable as reasonably
determined by Landlord, Base Rent shall be suspended until the Premises shall
have been restored to a tenantable condition; provided, however, that Landlord
may notify Tenant that the Premises will not be repaired, in which event this
Lease shall terminate and neither party shall have any further liability to the
other except for liabilities relating to the period prior to termination. If in
the reasonable estimate of Landlord and Tenant, it will take more than 180 days
to restore the Premises to a tenantable condition, Tenant may, within thirty
(30) clays of the occurrence of such damage, terminate the Lease by written
notice to Landlord and neither party shall have any further liability to the
other except for liabilities relating to the period prior to termination. If,
however, such damage or destruction does not render the Premises untenantable as
reasonably determined by Landlord, Landlord shall repair the same or cause the
same to be repaired following receipt of insurance proceeds from Tenant to the
extent such funds are available or from the Landlord's insurance if the damage
is to the portion of the Office Park covered by insurance purchased by the
Landlord. If such damage is caused by Tenant, Tenant's employees, agents or
invitees, then the full amount of rent shall continue to be due, whether or not
the Premises can be or are occupied and all such damage shall be repaired at the
expense of the Tenant. Tenant shall promptly reimburse Landlord for all expenses
incurred by the Landlord for repairs to the Premises for which the Tenant is
responsible hereunder.

24. CONDEMNATION. If the Premises or any material part thereof is taken by any
authority exercising the power of eminent domain and Tenant is unable to conduct
its business in the remainder of the Premises, as reasonably determined by
Landlord and Tenant, this Lease shall terminate as of the date of possession by
the condemnor. Tenant waives all claims against Landlord or any condemning
authority by reason of the complete or partial taking of the Premises, and shall
not be entitled to receive any part of any award which Landlord may receive,
hereby quitclaiming all interest therein to Landlord. In the event the Lease is
not terminated pursuant to this paragraph, then the Lease shall remain in full
force and effect as to the remainder of the Premises and the Base Rent shall be
pro-rated based on the remaining square footage of the Premises.

25. ATTORNEY'S Fees. If either Landlord or Tenant employs an attorney because of
the other's violation of any covenant, agreement or provision of this Lease, the
prevailing party in such action shall be paid its attorney's fees by the
non-prevailing party.

26. SUBORDINATION. This Lease shall be subject and subordinate at all times to
the lien of the mortgages now on the Premises and to all advances made or
hereafter to be made upon the security thereof and subject and subordinate to
the lien of any mortgage or mortgages which at any time may be made a lien upon
the Premises. The Tenant will execute and deliver within seven (7) days of a
written request therefor such further instrument or instruments evidencing such
subordination of this Lease to the lien of any such mortgage or mortgages as
shall be desired by any mortgagee or proposed mortgagee. The Tenant hereby
appoints the Landlord the attorney-in-fact of the Tenant, irrevocably, to
execute and deliver any such instrument or instruments for the Tenant.

         Notwithstanding the generality of the foregoing provisions of this
Paragraph 26, any mortgagee or lessor of Landlord shall have the right at any
time to subordinate any such deed of trust or mortgage or underlying lease to
this Lease, or to any of the provisions hereof, on such terms and subject to
such conditions as such mortgagee or lessor of Landlord may consider appropriate
in its discretion. At any time, before or after the institution of any
proceedings for the foreclosure of any such deed of trust or mortgage, or the
sale of the Office Park or any portion thereof containing the Premises under any
such mortgage, or the termination of any underlying lease, Tenant shall, upon
request of such mortgagee or lessor or any person or entities succeeding to the
interest of such mortgagee or lessor or the purchaser at any foreclosure sale
("Successor Landlord"), automatically attorn to and become the tenant (or if the
Premises has been validly subleased, the subtenant) of the Successor Landlord,
without change in the terms or other provisions of this Lease (or, in the case
of a permitted sublease, without change in this Lease or in the instrument
setting forth the terms of such sublease); provided, however, that the Successor
Landlord shall not be bound by any amendment or other modification to this Lease
without the consent of the Successor Landlord or by any payment made by Tenant
of Base Rent or Additional Rent for more than one (1) month in advance. This
agreement of Tenant to attorn to a Successor Landlord shall survive any such
foreclosure sale, trustee's sale, conveyance in lieu thereof or termination of
any underlying lease. Tenant shall upon demand at any time, before or after any
such foreclosure or termination, execute, acknowledge, and deliver to the
Successor Landlord any written instruments and certificates evidencing such
attornment as such Successor Landlord may reasonably require.

                                       11

<PAGE>

         No act or failure to act on the part of Landlord which would entitle
Tenant under the terms of this Lease, or by law, to be relieved of Tenant's
obligations hereunder or to terminate this Lease, shall result in a release of
such obligations or a termination of this Lease unless (i) Tenant has given
notice by registered or certified mail to any mortgagee or lessor of Landlord
whose address shall have been furnished to Tenant, and (ii) Tenant offers such
mortgagee or lessor of Landlord a reasonable opportunity to cure the default,
including time to obtain possession of the Premises by power of sale or judicial
foreclosure, if such should prove necessary to effect a cure.

         Tenant shall not unreasonably withhold, delay, or defer its written
consent to reasonable modifications to this Lease which are a condition of any
construction, interim or permanent financing for the Office Park, provided that
such modifications do not increase the obligations of Tenant hereunder or
materially and adversely affect Tenant's use and enjoyment of the Premises.

27. Agency. If Landlord appoints an agent to manage the Premises and collect the
rent due under this Lease, Landlord may authorize the agent to act for Landlord
under the terms of this Lease and Tenant shall in all cases comply with the
reasonable exercise by the agent of any and all of Landlord's rights under this
Lease.

28. NOTICE. Any notice pursuant to this Lease shall be in writing, mailed as
registered or certified United States mail, postage prepaid, or hand delivered
or sent by overnight express courier (with signed receipts) addressed as set
forth herein (or to the last address designated by such party in writing to the
other). Notices shall be deemed conclusively to have been given on the postmark
date, or the date of personal delivery, or on the business day after delivery by
overnight express courier, except notice of change of address which shall only
be deemed given upon actual receipt.

29. BROKERAGE. Landlord and Tenant warrant and represent to each other that,
other than Sullivan Properties, Inc. (the "Broker"), there was no broker or
agent instrumental in consummating this Lease, and that no conversations or
prior negotiations were had by or with any other broker concerning the renting
of the Premises. Tenant and Landlord shall indemnify and hold each other
harmless against any claims for brokerage or other commissions arising by reason
of a breach of the aforesaid representations and warranties. The commission
shall be paid by Landlord pursuant to a separate agreement.

30. RECORDING. Neither this Lease nor any memorandum hereof may be recorded
among the land records of the jurisdiction in which the Premises is located.

                                       12

31. ASSIGNMENT BY LANDLORD. The term "Landlord" shall be limited to mean and
include only the owner or owners, at the time in question, of the fee title to
the Premises. Landlord may transfer its interest in the Lease or the Premises
without the consent of Tenant. At any time, before or after any transfer of
Landlord's interest in the Premises, Tenant shall, upon request of such
transferee ("Successor Landlord"), automatically attorn to and become the tenant
(or if the Premises have been validly subleased, the subtenant) of the Successor
Landlord, without change in the terms or other provisions of this Lease, (or, in
the case of a permitted sublease, without change in this Lease or in the
instrument setting forth the terms of such sublease).

32. LANDLORD'S LIABILITY. Anything contained in this Lease to the contrary
notwithstanding, Tenant agrees that Tenant shall look solely to the estate and
property of Landlord in the Premises for the collection of any judgment or other
judicial process requiring the payment of money by Landlord for any default or
breach by Landlord under this Lease, subject, however, to the prior rights of
any mortgagee or lessor of the Premises. No other assets of Landlord or any
partners, shareholders, or other principals of Landlord shall be subject to
levy, execution or other judicial process for the satisfaction of Tenant's
claim.

33. GOVERNING LAW. This Lease shall be governed by and construed under the laws
of the Commonwealth of Virginia, without reference to its conflicts of laws
principles. Tenant and Landlord hereby consent to jurisdiction and venue in the
General District or Circuit Court for Spotsylvania County, Virginia or in any
other court in the Commonwealth of Virginia selected by Landlord if any suit is
brought relating to this Lease.

34. TIME OF Essence. Time is of the essence in this Lease.

35. FINANCIAL STATEMENTS. Prior to execution of the deed of lease, Tenant shall
provide Landlord with a current financial statement and financial statements for
the two (2) years prior to the current financial statement year. Such statements
shall be prepared in accordance with generally accepted accounting principles,
and, if such is the normal practice of Tenant, shall be audited by an
independent certified public accountant. If it is not the normal practice of
Tenant to prepare audited statements, then the unaudited statements shall be
certified to by the Tenant. Tenant acknowledges and agrees that Landlord may
inquire of Tenant's vendors and other creditors with respect to Tenant's
creditworthiness. Tenant agrees to hold harmless Landlord from any loss or
damage suffered by Tenant as a result of any such inquiries made by Landlord.

36. ESTOPPEL CERTIFICATES. Tenant shall, from time to time, within ten (10) days
after request from Landlord, certify, to the extent true, that this Lease is in
full force and effect and unmodified (or, if there have been modifications, that
the same is in full force and effect as modified and stating the modifications);
the dates to which the rent has been paid; that Tenant has accepted possession
of the Premises and that any improvements required by the terms of this Lease to
be made by Landlord have been completed to the satisfaction of Tenant; the
amount, if any, that Tenant has paid to Landlord as a Security Deposit; that
Tenant, as of the date of such certificate, has no charge, lien, or claim of

                                       13

<PAGE>

offset under this Lease or otherwise against rent or other charges due or to
become due hereunder; that, to the knowledge of Tenant, Landlord is not then in
default under the terms of this Lease; that, if Landlord has assigned this Lease
as collateral for a loan, and informed Tenant of the identity of the mortgagee,
Tenant will, upon written request of the mortgagee, pay rent directly to such
mortgagee; and such other matters as may be reasonably requested by Landlord or
any mortgagee, lessor or prospective purchaser of Landlord. Any such certificate
may be relied upon by Landlord, or any mortgagee, lessor or prospective
purchaser of Landlord. In the event that Tenant fails to provide Landlord with
an estoppel certificate as described and within the time period provided
hereinabove, Landlord is hereby appointed Tenant's attorney-in-fact for the
purpose of executing such estoppel certificate and delivering the same to any
mortgagee, lessor or prospective purchaser of Landlord, which appointment is
coupled with an interest and is therefore irrevocable.

37. AUTHORITY. Each individual executing this Lease on behalf of Landlord and
Tenant represents and warrants that he is duly authorized to execute and deliver
this Lease on behalf of Landlord or Tenant in accordance with a partnership
agreement or a duly adopted resolution of the Board of Directors or in
accordance with bylaws and that this Lease is binding upon Landlord and Tenant
in accordance with its terms.

38. SURVIVAL. Tenant's obligations contained in this Lease shall survive the
termination or expiration of the Lease.

hold harmless Landlord against and from any and all claims, liens, suits,
actions, debts, damages, costs, losses, liabilities, obligations, judgments, and
expenses (including, without limitation, court costs and attorneys' fees), of
any nature whatsoever as a result of Tenant's acts or omissions, arising from or
relating to (i) non-compliance with any Federal, state or local environmental
statutes including, without limitation, RCRA and CERCLA, as amended; or (ii) the
presence of any Hazardous Substance (as hereinafter defined) affecting the
Premises or surrounding areas in violation of applicable Legal Requirements. As

    THIS
      DEED OF COMMERCIAL OFFICE LEASE AGREEMENT (this “Lease”) is
      made as of the 16th day of May, 2005, by and between BDC
      Spotsylvania LLC, hereinafter referred to as “Landlord” and
E-OIR Technologies, Inc., a Virginia corporation, hereinafter
      referred to as “Tenant”.

     

    WITNESSETH,
      that for and in consideration of the
      rent hereafter reserved, and the covenants contained herein, the parties hereby
      agree as follows:

    

    1.

    Lease
      Premises.

    

    Landlord
      hereby leases to Tenant and Tenant hereby leases from
      Landlord for the term identified below, at the rental and upon the conditions
      set forth herein, approximately Six Thousand Seven Hundred Fifty (6,750)
      rentable square feet known as Suite 220 on the Second floor of the South Wing
      (“Second Floor Premises”) and One Hundred Fifty-One (151) rentable square feet
 known as Suite 190 on the First Floor of the South Wing
      (“First Floor Premises”) and identified on Exhibit A attached
      hereto (collectively, the “Premises”) of that certain building  located at
      10300 Spotsylvania Avenue, Fredericksburg, Virginia (the “Building”) (if there
      is more than one building on Landlord’s land operated as part of a common
      complex, then reference to “Building” hereunder shall mean and refer to all such
      buildings)  The parcel(s) of real property on which the Building is located
      together with the Building are hereinafter collectively referred to as the
      “Property.” The Premises do not include exterior faces of exterior walls and
      exterior window glass; anything beyond the interior face of demising walls;
      or
      any pipes, ducts, conduits, wires and fixtures serving other parts of the
      Building, except for Tenant-specific pipes, ducts, conduits, wires and fixtures
      which are wholly located within and serve only the Premises, and measurement
      will be based on the BOMA standard of measurement dated June 7, 1996 (ANSI/BOMA
      Z65.1-1996).  Tenant may use the common areas of the Building in common
      with other tenants subject to and in accordance with the terms and conditions
      hereinafter set forth.  The common areas (the “Commons Areas”) include the
      Building’s common lobbies, corridors, stairways, and elevators, the common
      walkways and driveways necessary for access to the Building, the common toilets,
      corridors and elevator lobbies of any multi-tenant floor, and the parking area
      for the Building.  All use of the Common Areas shall be only upon the terms
      set forth at any time by Landlord.  Tenant acknowledges and agrees that the
      roof of the Building is under the exclusive control of Landlord, that Tenant
      shall have no access to the roof without Landlord’s prior written consent and
      that Landlord reserves the right from time to time to install or allow the
      installation of telecommunications devices on the roof.

    

    2.

    Term
      and Possession.

    

    2.1

    Term.
 Subject
      to the terms and conditions set forth in this
      Lease, the term (the “Term”) of this Lease shall be for approximately five (5)
      years, commencing on the date (the “Commencement Date”) which is the later of
      (x) August 1, 2005 or (y) the earlier of (i) the date of delivery of the
      Premises by Landlord to Tenant following substantial completion of the Tenant
      Improvements (hereinafter defined) as determined by the Landlord or (ii) October
      15, 2005 or (iii) occupancy of the Premises by Tenant and ending on the last
      day
      of the month in which the fifth anniversary date of the Commencement Date
      occurs, and ending on the last day of the month in which the fifth anniversary
      date of the Commencement Date occurs.  Substantial Completion shall mean
      that the Tenant Improvements have been completed to such an extent that a
      certificate of occupancy would be issued by Spotsylvania County if timely
      applied for by Tenant.  Landlord agrees to assist Tenant in processing the
      application.  Landlord may, by telecopier or other notice, notify Tenant of
      the date of delivery.

    

    2.1.1

    Extension
      Option.  Provided that this Lease is in full force
      and effect, the Tenant shall be entitled to extend this Lease for one (1)
      additional term (hereinafter referred to as “Extension Term”) of five (5) years,
      commencing on the first day next succeeding the last day of the last day of
      the
      initial Lease Term, upon the same terms and conditions and provisions as are
      provided for in this Lease, except that (i) the Basic Monthly Rent payable
      during the Extension Term shall be the prevailing market rate, subject to
      escalation, as determined by Landlord, (ii) Landlord has no obligation for
      any
      tenant improvements or tenant allowances, and (iii) there shall be no
      further extension; provided, however, if Tenant is in Default hereunder at
      any
      time from Tenant’s delivery of the Extension Notice (hereinafter defined) to the
      commencement of such Extension Term, at Landlord’s option, such Extension Term
      shall be null and void.  Tenant shall provide Landlord with written notice
      (“Extension Notice”) of its intent to exercise the extension option not less
      than nine (9) months prior to the expiration of the last day of the initial
      Lease Term; upon Tenant’s failure to so provide the Extension Notice, time being
      of the essence, Tenant shall have no further right to extend the Lease.
 Upon receipt of Tenant’s Extension Notice, Landlord shall advise Tenant of
      Landlord’s determination of the prevailing market rate within ten (10) days of
      such receipt (except if Robert Sandler is on vacation, then within five (5)
      days
      of Robert Sandler returning from vacation).  Upon receipt of Landlord’s
      determination, if Tenant disagrees with Landlord’s prevailing market rate,
      Tenant may negotiate with Landlord for a period of twenty (20) days.  If
      Tenant and Landlord fail to agree on the prevailing market rate, Tenant shall
      have the right to withdraw its Extension Notice by notice in writing or
      electronically to Landlord delivered prior to the expiration of such twenty
      (20)-day period, in which case Tenant shall have no further right to extend
      the
      Lease.  Reference to the word “Term” hereunder shall mean and include the
      initially stated term, as well as any extensions or renewals thereof, including
      any exercised (but not rescinded) Extension Term.

    

    2.1.2

    Termination
      Option.  Tenant shall have the one-time right to
      terminate the Lease effective as of the end of the thirty-sixth full calendar
      month following the Commencement Date, by giving written notice to the Landlord
      prior to the expiration of the twenty-seventh full calendar month following
      the
      Commencement Date (time being of the essence herein), which notice (in order
      to
      be valid) shall be accompanied by payment of the Termination Fee (hereinafter
      defined) and which notice shall specify the termination date; provided however,
      if Tenant is in Default at any time hereunder beyond any applicable cure period
      (whether before or after the termination notice), at Landlord’s option, such
      termination election shall be null and void, and Landlord may use any portion
      of
      the Termination Fee paid to offset against any amounts owed by Tenant under
      the
      Lease.  The Termination Fee is equal to the sum of (i) four (4) months of
      Rent then being paid by Tenant on a monthly basis (including without limitation
      estimated pass-throughs), plus (ii) the unamortized portion of the cost of
      all
      leasehold improvements, leasing commissions, attorney fees, rental abatements
      and other concessions incurred or provided by Lessor in connection with this
      Lease. Upon request, Landlord shall calculate the Termination Fee and provide
      the amount thereof to Tenant.  The Termination Fee shall be calculated by
      Landlord by first amortizing the cost of all leasehold improvements, leasing
      commissions, attorney fees, rental abatements and other concessions in equal
      monthly installments over the Term (or if incurred in connection with any Lease
      amendment, amortized over the portion of the Term commencing with the effective
      date for the initial full monthly payment of Rent for the Lease amendment)
      at
      the rate of nine percent (9%) per annum (compounded annually) and then
      determining the unamortized portion thereof as of the effective date of
      termination.  Tenant, in addition to the Termination Fee, shall remain
      obligated for all Basic Monthly Rent, Additional Rent and other sums due under
      the Lease up to and including the effective date of termination, even though
      such amounts may be billed subsequent to such date.  Tenant’s obligations,
      and Landlord’s rights and remedies (including without limitation, the right to
      recover reasonable attorneys fees as permitted by this Lease), with respect
      to
      all such sums, any other amounts due and owing to Landlord and any other of
      Tenant’s obligations or liabilities accruing prior to the date of termination
      shall survive any such termination.  .

    

    2.1.3

    Right
      of First Notification.  Prior to Landlord’s initial
      leasing of space immediately adjacent to the Premises on the 2nd
      floor (as identified on Exhibit A) to a third party not already a tenant,
      Landlord shall notify Tenant by telecopier at 703-704-1351  Attn. Bill
      Elliott, that Landlord is in negotiations with a prospective tenant for such
      space.  Such notice shall include the rental rate that Landlord will charge
      to Tenant.  Landlord agrees not to execute a lease for such space to a
      third party for a period of seven (7) days following the sending of such notice
      to allow Tenant to approach Landlord about leasing such space..

    

    2.2

    Possession.
 Landlord
      shall reasonably attempt to deliver
      possession of the Premises within one hundred twenty (120) days of Lease
      execution, the anticipated date of commencement (the “Anticipated Commencement
      Date”).  If Landlord should be unable to deliver possession of the Premises
      to the Tenant on the Anticipated Commencement Date or thereafter for any reason,
      Landlord shall not be subject to any liability, claims or damages for failure
      to
      give possession on said date and this Lease shall not be terminated or
      terminable by reason of such delay.  Under such circumstances, the rent
      reserved and covenanted to be paid herein shall not commence until the
      possession of the Premises is tendered by Landlord which may be confirmed by
      Landlord’s delivery of notice to Tenant that possession has been delivered
      following substantial completion of the Tenant Improvements, provided, however,
      that in the event any delay in tendering possession to the Tenant or in Tenant’s
      taking occupancy of the Premises beyond the Anticipated Commencement Date is
      caused by any act, delay or omission of Tenant, its employees, agents,
      contractors or invitees, Tenant shall remain obligated to commence paying rent
      hereunder beginning on the earlier to occur of (i) the Anticipated Commencement
      Date or (ii) the date the Landlord tenders possession of the Premises to Tenant.
       If permission is given to the Tenant to enter into possession of the
      Premises, or to occupy space other than the Premises prior to the Anticipated
      Commencement Date Tenant covenants and agrees that such occupancy shall be
      deemed to be under all the terms, covenants and conditions of the provisions
      of
      this Lease, and that the Rent shall commence on such date. Tenant covenants
      and
      agrees to execute and deliver such documentation as Landlord may reasonably
      require confirming the Commencement Date and such other matters as Landlord
      or
      any lender may reasonably request.  In addition, Landlord may elect to send
      a letter establishing the Commencement Date (if not a specific calendared date
      under Section 2.1), which shall be binding for all purposes unless Tenant sends
      written notice of objection within five (5) business days of receipt.
 

    

    2.3

    Early
      Possession for Tenant Fit-Up.  Upon written request by
      Tenant, Tenant shall be given access to the Premises twenty-one (21) days prior
      to the Commencement Date for the purpose of installing such equipment as may
      be
      approved by Landlord, provided Tenant does not interfere with any work being
      done by Landlord on the Premises.  Tenant hereby indemnifies Landlord for
      all losses, costs, damages and claims including reasonable attorneys’ fees
      arising out of any delays, damages to the Building or other matters arising
      out
      of Tenant’s access, and shall present Landlord with satisfactory certificates of
      insurance as a condition to gaining such access.

    

    2.4

    Acceptance
      of Premises.  Tenant acknowledges that the
      Premises will be delivered and accepted in its then “as is,” “where is”
condition with no expectation that Landlord will or should perform or otherwise
      contribute towards the cost of any leasehold improvements, except that Landlord
      shall construct the Tenant Improvements (hereinafter defined) for the Second
      Floor Premises pursuant to Exhibit D, with the First Floor Premises being
      delivered and accepted “as is”, subject to demising; provided, however that in
      no event shall Landlord’s obligations for the cost of the Tenant Improvements
      exceed Twenty-Five Dollars and No/100 ($25.00) per square foot of the net
      rentable square footage of the Second Floor Premises (“Landlord Contribution
      Cap”).  

    

    2.4.1
 If
      at anytime the Landlord determines in good faith
      that the cost of Tenant Improvements will exceed the Landlord Contribution
      Cap,
      Tenant shall immediately, upon demand (whether made prior to or after completion
      of the Tenant Improvements), (i) pay to the Landlord the amount of the excess
      (“Excess Costs”), as Additional Rent hereunder, or (ii) with respect to the
      first Ten Dollars ($10) per square foot of Excess Costs, elect to have such
      excess amortized in the Basic Monthly Rent over the initial approximate five
      (5)
      year Term at eight percent per annum (8%).  Unless Tenant shall have paid
      Landlord the first $10 p.s.f. of Excess Costs, then Tenant shall be deemed
      to
      have elected to have such excess not exceeding $10 p.s.f. to be amortized into
      the Basic Monthly Rent.  Landlord shall not be required to continue with
      construction of the Tenant Improvements until Tenant has so paid the amount
      of
      the Excess Costs, other than those being amortized into the Basic Monthly Rent.
       If Tenant has elected or is deemed to have elected to have a portion of
      the Excess Costs amortized into the Basic Monthly Rent, such amortized amount
      shall be referred to as the “Amortized Allowance.”  

    

    

    3.

    Rent.

    

    3.1

    Basic
      Monthly Rent.  Upon Tenant’s execution of the Lease,
      Tenant shall prepay one full month of Basic Monthly Rent to be applied to the
      first installment(s) thereof due hereunder.  Thereafter, Tenant covenants
      and promises to pay to Landlord for the Premises, commencing on the sooner
      of
      October 15, 2005 or the Commencement Date, the Basic Monthly Rent without
      deduction or demand or set off whatsoever, in lawful money of the United States
      of America, in advance on the first day of each calendar month during the Term
      hereof, to and at the office of Bernstein Management Corporation (the “Agent”),
      5301 Wisconsin Avenue, NW, Suite 600, Washington, DC  20015, or at such
      other place as Landlord may from time to time designate to Tenant in writing.
       In addition to the Basic Monthly Rent, Tenant shall pay all Additional
      Rent and other amounts payable hereunder in lawful money of the United States
      of
      America, each without set-off, deduction, offset or counterclaim, in accordance
      with the terms set forth herein.  Except as specified elsewhere in this
      Lease, Additional Rent shall be paid by Tenant with the next monthly installment
      of Basic Monthly Rent falling due.  Rent checks shall be made payable to
      Bernstein Management Corporation, or to such other party as Landlord shall
      direct. Should the Commencement Date fall on a day other than the first day
      of a
      calendar month or the Term expire on a day other than the last day of a calendar
      month, the parties agree that the monthly rental for such partial calendar
      month
      in the Term shall be pro-rated.  The basic monthly rent (“Basic Monthly
      Rent”) is payable monthly as follows:

    The
      foregoing amounts of Basic Monthly Rent are subject to
      modification in the event that Tenant elects to obtain the Amortized Allowance,
      in which event, Tenant, upon Landlord’s request, shall execute within five (5)
      days of request a Declaration furnished by Landlord confirming the revised
      Basic
      Monthly Rent; provided however, that in no event shall any amount of the
      Amortized Allowance amortized into the Basic Monthly Rent be abated.

    

    For
      purposes of the above rent schedule, the Lease Year 1 shall
      mean the period commencing on the  Commencement Date, and ending on last
      day of the month in which the first anniversary date of the Commencement Date
      occurs, and each subsequent Lease Year shall be the 12-month period
      thereafter.

    

    3.2

    Additional
      Rent.

    

    3.2.1

     Tenant
      shall pay to Landlord, in accordance with Section
      3.2.3 below,  as Additional Rent, “Tenant’s Share” defined as the sum of
      Tenant’s Separate Services (as hereinafter defined) plus Tenant’s Pro Rata Share
      (as hereinafter defined) of any increase in Landlord’s Costs (as hereinafter
      defined) above the Base Costs (as hereinafter defined).  All sums of any
      type or kind, other than Basic Monthly Rent,  required to be paid by Tenant
      to Landlord hereunder shall be deemed to be Additional Rent whether or not
      the
      same may be designated as such herein. 

    

    3.2.2

    For
      purposes of this Lease:

    

    (i)

    “Tenant’s
      Separate Services” shall mean all Operating Expenses
      which are attributable solely to Tenant’s use and occupancy of the Premises,
      such as the cost of electricity consumed in the Premises for any supplemental
      HVAC equipment or the like, as measured by memorandum or sub-meters, special
      janitorial services or other services provided by Landlord at Tenant’s request.
 Normal electric consumption shall be included in Operating Expenses (as
      hereinafter defined).

    

    (ii)

    “Tenant’s
      Pro Rata Share” shall mean Four and 03/100 percent
      (4.03%), representing the ratio that the rentable area of the Premises (6,901
      square feet)  bears to the total rentable area of the Building (152,501
      square feet).

    

    (iii)

    “Landlord’s
      Costs” shall mean Taxes and Assessments and Operating
      Expenses but excluding those Operating Expenses paid by Tenant as Tenant’s
      Separate Services.

    

    (iv)

    “Taxes
      and Assessments” shall mean all taxes and assessments and
      governmental charges (including personal property and real estate taxes),
      whether federal, state, county or municipal, and whether they be assessed or
      levied by taxing districts or authorities presently taxing the Property by
      others subsequently created, and any other taxes and assessments (including
      franchise taxes) attributable to the Property or its operation, whether or
      not
      directly paid by Landlord, excluding, however, federal and state taxes on income
      of the Landlord, unless such income taxes replace real estate taxes.  The
      Tenant shall be responsible for ad valorem taxes on its personal property.
       If at any time during the Term the methods of taxation shall be altered so
      that in addition to or in lieu of or as a substitute for the whole or any part
      of any taxes levied, assessed or imposed there shall be levied, assessed or
      imposed (i) a tax, license fee, excise or other charge on the rents received
      by
      Landlord with respect to the Building, or (ii) any other type of tax or other
      imposition in lieu of, or as a substitute for, or in addition to, the whole
      or
      any portion of any taxes, then the same shall be included as taxes for the
      purposes hereof.  A tax bill or true copy thereof, if submitted by Landlord
      to Tenant, shall be conclusive evidence of the amount of taxes assessed or
      levied as well as of the items taxed.  Reasonable expenses (including
      without limitation contingency-based fees), including attorneys’ fees, expert
      witness fees and similar costs, incurred by Landlord in obtaining or attempting
      to obtain a reduction of any taxes shall be added to and included in the amount
      of any such taxes. Taxes which are being contested by Landlord shall
      nevertheless be included for purposes of the computation of the liability of
      Tenant hereunder, provided, however, that if Landlord is successful in
      contesting any such taxes, excess taxes paid by Tenant shall be applied as
      a
      credit toward the next installment(s) of taxes due.  Landlord shall have no
      obligation to contest, object to or litigate the levying or imposition of any
      taxes and may settle, compromise, consent to, waive or otherwise determine
      in
      its discretion to abandon any contest with respect to the amount of any taxes
      without consent or approval of Tenant.

    

    (v)

    “Operating
      Expenses” shall mean all of the costs and expenses paid
      or incurred in operating, managing, administering, servicing, repairing and
      maintaining the Building, the Property and surrounding sidewalks, alleys and
      parking areas as determined by Landlord in accordance with standard accounting
      practices (except that Landlord may amortize an expense over multiple years
      in
      lieu of passing the entirety of such expense thru in the year of its
      expenditure), whether paid to employees of Landlord or independent contractors
      engaged by Landlord, and shall include the following costs by way of
      illustration, but not limitation:  water and sewer charges, insurance
      premiums, utilities, janitorial services, labor, including direct labor
      overhead, air conditioning and heating, landscaping, elevator maintenance,
      supplies, costs and upkeep of all parking and common areas, supply and cleaning
      of uniforms and work clothes, security for the Building, fees incurred for
      the
      management of the Building including legal, inspection, consultation and
      accounting fees, costs of repair, maintenance and replacement of exterior roofs,
      all charges for repair and maintenance of all mechanical equipment and building
      systems (exclusive of those Tenant is obligated to repair and maintain
      hereunder) and a property management fee equal to the generally prevailing
      rate
      consistent with the type of occupancy and the services rendered, but not less
      than three percent (3%) nor more than five percent (5%) of the total rent
      collected from tenants of the Property.  Operating Expenses shall not
      include depreciation of the Building of which the Premises are a part or
      equipment therein, mortgage loan payments, executive salaries and any brokerage
      commissions but shall include amortization, with reasonable interest, of capital
      items which reduce Operating Expenses or are required by governmental
      authority.

    

    (vi)

    “Base
      Costs” shall mean Landlord’s Costs incurred for or
      attributable to the 2005 calendar year.

    

    (vii)

    “Rent”
shall
      mean Basic Monthly Rent and Additional Rent.

    

    3.2.3

    Payment
      of Additional Rent. Tenant shall remit to Landlord as
      Additional Rent, simultaneously with the next installment of Basic Monthly
      Rent,
      the amount of any Tenant’s Separate Services paid for by Landlord during the
      then current month.  In addition, beginning January 1, 2006 (the
“Pass-Through Commencement Date”), and continuing for each subsequent calendar
      year or portion thereof during the Term, Landlord’s Costs shall be passed
      through to Tenant based on the actual increase over Base Costs. In addition,
      commencing with the Pass-Through Commencement Date and thereafter simultaneously
      with each monthly payment of Basic Monthly Rent hereunder for the balance of
      the
      Term, Tenant shall pay to Landlord an estimated amount of Additional Rent on
      account of Landlord’s Costs above Base  Costs.  Landlord’s estimate of
      Additional Rent payable for any given year shall be equal to 105% of Landlord’s
      Costs above Base Costs for the immediately preceding year provided, however,
      that in the event Landlord determines during the course of any year that
      Landlord’s Costs for such year shall exceed 105% of such prior year’s costs, (i)
      Tenant shall, within ten (10) days of receiving a demand therefor, pay a lump
      sum to Landlord equal to the excess of (a) the amount which would have been
      payable by Tenant based upon such actual higher costs from and including January
      1 of such year through the date of the notice setting forth the increase in
      Landlord’s Costs beyond (b) the amount of Additional Rent actually paid by
      Tenant for such period and (ii) the monthly payments of Additional Rent for
      the
      balance of such year shall be increased accordingly. 

    

    3.2.4

    Reconciliations.
 Within
      a reasonable time after the end of
      each calendar year during the Term, Landlord will furnish to Tenant a statement
      setting forth the actual amount of Tenant’s Separate Services and
 Landlord’s Costs actually incurred for the immediately preceding calendar
      year together with Tenant’s Share thereof provided, however, that the failure by
      Landlord to provide such a statement by any specific date shall not constitute
      a
      waiver by Landlord of its right to require an increase in the Additional Rent
      for the then current year or provide Tenant with any defense or setoff against
      its obligations under this Lease.  In the event that the estimated amount
      paid by Tenant for such year under Section 3.2.3 (the “Estimated Payments”) is
      less than the actual amount payable by Tenant pursuant to such statement (the
      “Required Amount”), Tenant shall reimburse Landlord for such deficiency by
      making a lump sum payment of such deficiency within ten (10) days following
      receipt of Landlord’s demand therefor.  In the event that the Estimated
      Payments for any year exceeds the Required Amount for such year, the excess
      shall be credited by Landlord to the next installment(s) of Additional Rent
      coming due and payable or, in the event such calendar year is the last year
      of
      the Term, remitted by Landlord to Tenant provided Tenant is not in default
      of
      its obligations under this Lease and there are no damages to the Premises or
      the
      remainder of the Property caused by Tenant or its employees, agents or
      contractors. The obligations of Landlord and Tenant under this subsection shall
      survive the expiration or termination of this Lease.

    

    3.2.5

    Pro-Rata
      Calculation.  Should this Lease commence or
      terminate at any time other than the first (1st) day of a calendar year, the
      cost adjustment referred to in Subsections 3.2.1, 3.2.2, 3.2.3 and 3.2.4 shall
      be calculated for the commencement or termination year on a pro rata basis,
      based upon the number of calendar days during which Tenant leases or is deemed
      to lease the Premises.

    

    3.2.6

    Tenant’s
      Right to Audit.  Each statement provided by Landlord
      pursuant to this Section 3.2 shall be conclusive and binding upon Tenant unless
      fifteen (15) days after receipt of the statement, Tenant shall notify Landlord
      that it disputes the correctness of the statement, specifying the respects
      in
      which the statement is claimed to be incorrect.  If Landlord and Tenant are
      unable to resolve the dispute, Tenant shall then have the right to request
      that
      Landlord provide, at Tenant’s expense, an audit of its books and records
      relating to the statement.  Pending determination of the dispute, Tenant
      shall pay within ten (10) days from notice any amounts due from Tenant in
      accordance with the statement, but such payment shall be without prejudice
      to
      Tenant’s position.  If the dispute shall be resolved in Landlord’s favor,
      Tenant shall pay to Landlord upon demand all other costs and expenses incurred
      by Landlord in connection therewith.

    

    3.2.7

    Adjustments
      to Costs.  Notwithstanding any other provisions
      herein to the contrary: (i) in the event the Building is not fully occupied
      during the year, an adjustment shall be made in computing the Operating Expenses
      for such year so that the costs shall be computed for such year as though the
      Building had been ninety-five percent (95%)occupied during such year; and (ii)
      the Landlord shall have the right, in its reasonable judgment (and upon
      reasonable substantiation of such allocation to the Tenant), to allocate
      Operating Expenses to the Tenant, or to other tenants of the Building, in a
      manner which deviates from the exact Tenant’s Pro Rata Share, or those of such
      other tenants, as may be necessary to more accurately reflect accountability
      for
      unusual or extra costs resulting from excessive usage, the manner of layout
      or
      finishes requiring special maintenance, or the like.  The terms of this
      Subsection shall be solely for the benefit of the Landlord and may not be relied
      upon nor construed for the benefit of the Tenant, other tenants in the Building,
      or any other person.  

    

    3.3

    Late
      Charge.  Tenant hereby recognizes and acknowledges that
      if rental payments are not received within ten (10) days of when due, Landlord
      will suffer damages and additional expenses thereby and Tenant therefore agrees
      that a late charge equal to five percent (5%) of the Basic Monthly Rent and
      any
      additional rent or payments hereunder may be assessed by Landlord or Agent
      as
      additional rental.  Furthermore, Landlord or Agent shall have the right to
      require that all rental payments be made by certified or cashier’s check, in the
      event (i) any of Tenant’s checks are “bounced”, dishonored or returned for any
      reason, or (ii) Tenant monetarily defaults two or more times.  All bank
      service charges resulting from any checks of Tenant which are dishonored or
      returned for any reason shall be borne by Tenant.

    

    4.

    Security
      Deposit.

    

    4.1

    Delivery
      of Security Deposit.  Tenant shall deposit with
      Landlord, upon execution hereof, Twenty Thousand Five Hundred Eighty-Nine
      Dollars and 76/100 ($20,589.76) as security for the faithful performance of
      Tenant’s obligations hereunder (the “Security Deposit”).  Tenant shall earn
      no interest on the Security Deposit held by Landlord. 

    

    4.2

    Use
      of Security Deposit.  The Security Deposit shall be held
      by Landlord as security for the faithful performance and observance by Tenant
      of
      the terms, provisions and conditions of this Lease.  Landlord may use,
      apply or retain all or any portion of the Security Deposit for the payment
      of
      any past due rent or for the payment of any other sum to which Landlord may
      become entitled under this Lease or by law by reason of Tenant’s default or to
      compensate Landlord for any direct loss or damage which Landlord may suffer
      including, without limitation, the cost of replacing or repairing any equipment
      damaged or removed from the Premises and the cost of repairing any damage to
      the
      Premises or the Building.  Tenant shall have no right to apply the Security
      Deposit or any portion thereof to any rent hereunder, but the Security Deposit
      may be so applied, at Landlord’s option, from time to time.  If Landlord so
      uses or applies all or any portion of the Security Deposit, Tenant shall within
      ten (10) days after written demand therefor, deposit cash with Landlord in
      the
      amount sufficient to restore the Security Deposit to the full amount of the
      Security Deposit and Tenant’s failure to do so shall be a Default under this
      Lease.  Landlord’s application of any portion of the Security Deposit shall
      not cure any Default hereunder and Landlord shall be free to exercise such
      other
      rights and remedies as provided hereunder, at law or in equity.  Provided
      Tenant is not in default of its obligations under this Lease and there are
      no
      damages to the Premises or the remainder of the Property caused by Tenant or
      its
      employees, agents or contractors, the Security Deposit (or so much thereof
      as
      has not theretofore been applied by Landlord or returned to Tenant), shall
      be
      returned to Tenant within forty-five (45) days after the expiration of the
      Term
      and after Tenant has vacated the Premises.

    

    Upon
      written request made by Tenant to Landlord sent after the
      expiration of the first twelve (12) full calendar months for which Tenant is
      obligated to pay Basic Monthly Rent hereunder, the Tenant shall be entitled
      to
      the return of Ten Thousand Two Hundred Ninety-Four Dollars and 88/100
      ($10,294.88) out of the Security Deposit; provided however, that if Tenant
      is or
      is then in monetary default (no notice required) or non-monetary Default (after
      notice and cure period), or during the Term has been in monetary Default (if
      applicable, after notice and cure period) for more than twenty (20) consecutive
      days, as of the date of Landlord’s receipt of the timely-given request notice,
      then Tenant shall not be so entitled to the return of such portion of the
      Security Deposit.

    

    4.3

    Letter
      of Credit.  The Security Deposit may be made in the
      form of a letter of credit if the issuer thereof is approved by Landlord in
      advance and the form thereof (i) is approved in advance by the Landlord; (ii)
      provides that it is automatically renewable for a term of no less than one
      (1)
      year unless the issuer gives Landlord at least 45 days advance prior notice
      of
      non-renewal; (iii) provides that it is expressly transferable and assignable
      by
      the then current beneficiary without the consent or joinder of Tenant and
      without payment of a transfer fee; (iv) has as an attachment all required
      transfer and assignment documentation; and (v) provides that the sole condition
      to the draw is the presentation of the letter of credit (which may be by
      overnight delivery and can be made via a copy thereof in lieu of the original
      in
      the event of a partial draw) and an affidavit to the effect that “default has
      occurred under this Lease and the person requesting the draw is authorized
      on
      behalf of the then current beneficiary to make the draw and receive the
      proceeds.”  If the Security Deposit is made in the form of a letter of
      credit, it shall be an immediate default hereunder with no notice or cure period
      required, if less than thirty (30) days shall remain until the expiry date
      (or
      until the expiration of the initial or renewal term of the letter of credit)
      of
      any letter of credit posted hereunder, and Tenant shall not have renewed or
      replaced (in accordance with the foregoing) such letter of credit for the longer
      period of (x) the resolution of any then pending litigation, injunctive action
      or proceeding (including without limitation, bankruptcy proceeding) having
      the
      effect of prohibiting a draw on the Security Deposit letter of credit, plus
      two
      months, or (y) an additional one (1)-year period.  In such event, Landlord
      may immediately draw down on the letter of credit, and hold the proceeds thereof
      as a cash security deposit or apply in accordance with the terms hereof.
 In the event that the letter of credit Security Deposit is lost or
      destroyed, Tenant shall upon request by the then current beneficiary, cause
      a
      replacement letter of credit to be issued (provided proper affidavit by the
      beneficiary is made regarding the loss or destruction of the letter of credit).
      

    

    5.

    Tenant’sUse
      and Covenants.

    

    5.1

    Subject
      to Section 5.2, the Premises shall be used and occupied by
      the Tenant only for office use under the business name of E-OIR Technologies,
      Inc. and for no other use.

    

     

    5.2

    Prohibited
      Uses; Covenants of Tenant.  Tenant shall not use,
      or permit the use of, all or any part of the Premises for any disorderly,
      illegal or hazardous purpose and will not manufacture any commodity therein
      other than computer software.  Tenant shall not use, or permit the use of,
      all or any part of the Premises for any purpose that interferes with the use
      or
      enjoyment by other tenants of any portion of the Building, nor which, in
      Landlord’s opinion, impairs, or might impair, the reputation or value of the
      Property.  Tenant shall not use utility services in excess of amounts
      reason­ably determined by Landlord to be within the normal range of demand
      for general office use.  Tenant shall not obstruct any of the Common Areas
      or any portion of the Property outside the Premises, and shall not place or
      permit any signs, curtains, blinds, shades, awnings, aerials or flagpoles,
      or
      the like, visible from outside the Premises.  Tenant shall keep the
      Premises in a neat and clean condition.  Tenant shall pay before
      delinquency any and all taxes, assessments and public charges levied, assessed
      or imposed upon Tenant’s business, upon the leasehold estate created by this
      Lease or upon the Tenant’s fixtures, furnishings or equipment in the Premises.
 Tenant shall not strip, overload, damage or deface the Premises, or the
      hallways, stairways, elevators, parking facilities or other public areas of
      the
      Building, or the fixtures therein or used therewith, nor permit any hole to
      be
      made in any of the same. Tenant shall not install any equipment of any kind
      or
      nature which will or may necessitate any changes, replacements or additions
      to,
      or in the use of, the water system, heating system, plumbing system, air
      conditioning system or electrical system of the Premises or the Building,
      without first obtaining the written consent of Landlord to be withheld in
      Landlord’s sole discretion, except if the additions relate to the HVAC or
      electrical system in connection with partitioning or creating new office areas,
      and the building systems are not adversely affected, then Landlord’s consent
      shall not be unreasonably withheld.  Tenant shall comply with the
      Requirements (as hereinafter defined).  Tenant will not use or occupy the
      Premises in violation of any Requirement. If any governmental authority,
      quasi-governmental authority, mortgagee or insurance company shall contend
      or
      declare that the Premises are being used for a purpose which is in violation
      of
      any Requirement, then Tenant shall, upon five (5) days’ notice from Landlord,
      immediately discontinue such use of the Premises, unless such use is of such
      a
      nature that, in Landlord’s reasonable judgment, a more expeditious
      discontinuance is required, in which case Tenant shall immediately discontinue
      such use.  If thereafter the party asserting such violation threatens,
      commences or continues criminal or civil proceedings against Landlord for
      Tenant’s failure to discontinue such use, in addition to any and all rights,
      privileges and remedies given to Landlord under this Lease for default herein,
      Landlord shall have the right to terminate this Lease forthwith.  Tenant
      shall indemnify and hold Landlord harmless from and against any and all
      liability for such violation or violations, which obligation shall survive
      the
      expiration or termination of this Lease.

    

    The
      term “Requirements” as used herein shall mean all laws,
      statutes, ordinances, orders, rules, building codes, regulations and
      requirements of all federal, state and municipal governments, and the
      appropriate agencies, offices, departments, boards and commissions thereof,
      and
      the board of fire underwriters and/or the fire insurance rating organization
      or
      similar organization performing the same or similar functions, whether now
      or
      hereafter in force, applicable to the Building or any part thereof and/or the
      Premises, including, but not limited to, all those relating to environmental
      or
      trash disposal, hazardous waste and sorting, and Americans with Disabilities
      Act
      requirements. The Requirements shall also include all requirements of any
      present or future mortgagee or ground lessor of Landlord as to the manner of
      use, occupancy, maintenance, repair or condition of the Premises and/or the
      Building, and the requirements of the carriers of all fire insurance policies
      maintained by Landlord on the Building as well as the Landlord’s Rules and
      Regulations attached hereto as Exhibit C.

    

    5.3

    Tenant’s
      Maintenance.  Tenant, at Tenant’s sole expense,
      shall repair, maintain and replace any and all Supplemental (hereinafter
      defined) heating, ventilating and air conditioning equipment; Supplemental
      plumbing facilities, including without limitation, toilets, faucets and the
      like
      (exclusive of the incoming main water lines); any other Supplemental standard
      mechanical equipment; Supplemental electrical system; Supplemental lighting
      system, including without limitation, bulbs; Tenant’s telephone system; and any
      Supplemental access control or security system.  “Supplemental” shall mean
      any above building standard equipment or system, or any supplemental or stand
      alone equipment or system installed by or on behalf of Tenant or a former tenant
      serving the Premises; Supplemental shall specifically exclude the
      building-standard common area bathrooms.  Tenant shall maintain a service
      contract with a licensed and bondable mechanical contractor approved by
      Landlord, with a scope of service acceptable to Landlord, for all of the HVAC
      equipment and systems Tenant is obligated to maintain hereunder, and shall
      provide a copy of the same to Landlord upon the execution thereof and any
      renewal thereof.

    

    5.4

    Floor
      Load; Prevention of Vibration and Noise.  Tenant shall
      not place a load upon the floor of the Premises exceeding the [100] pounds
      per
      square foot such floor was designed to carry, as determined by Landlord or
      its
      structural engineer.  Partitions shall be considered as part of the load.
 Landlord may prescribe the weight and position of all safes, files and
      heavy equipment that Tenant desires to place in the Premises, so as to properly
      distribute their weight.  Tenant’s business machines and mechanical
      equipment shall be installed and maintained so as not to transmit noise or
      vibration to the Building structure or to any other space in the Building.
       Tenant shall be responsible for the cost of all structural engineering
      required to determine structural load and all acoustical engineering required
      to
      address any noise or vibration caused by Tenant.

    

    6.

    Services
      Furnished by Landlord.  

    

    Landlord
      shall furnish services, utilities, facilities and
      supplies as shown on the Landlord Services list attached as Exhibit
      B.  If Landlord furnishes any additional services at Tenant’s
      request, such services shall be charged at reasonable rates established by
      Landlord, which shall be considered additional rent.

    

    6.1

    Repairs
      and Maintenance.  Landlord shall repair and maintain
      the Common Areas and structural portions of the Building and the basic (i.e.,
      non-Supplemental) plumbing, electrical, mechanical and heating, ventilating,
      and
      air-conditioning and sprinkler (if any) systems therein, including the roof
      and
      windows, the costs of all of which shall be Operating Expenses.  In the
      event, however,  that any such repairs are necessitated by reason of any
      act or omission by Tenant, its employees, agents, licensees, invitees,
      contractors or anyone entering the Premises by force, Tenant agrees to promptly,
      upon demand, reimburse Landlord for the full costs thereof.  It is
      expressly understood that Landlord has no obligations hereunder except for
      those
      which are expressly stated herein or which are non-waivable under applicable
      law.  Except as expressly set forth above, all other repairs and
      maintenance to the Premises shall be the responsibility of Tenant.

    

    6.2

    Quiet
      Enjoyment.  Upon Tenant’s paying the Rent and
      performing its other obligations hereunder, Landlord gives the covenant of
      quiet
      enjoyment of the Premises to Tenant, subject to the provisions hereof and the
      terms of any mortgage, deed of trust or ground lease to which this Lease is
      subordinate.

    

    6.3

    Insurance.
 Landlord
      shall insure the Property, including the
      Building (with limits no less than eighty percent of the actual replacement
      cost
      of same) against damage by fire and standard extended coverage perils, and
      shall
      carry public liability insurance, all in such reasonable amounts with such
      reasonable deductibles as would be carried by a prudent owner of a similar
      Building in the area.  Landlord may carry any other forms of insurance as
      it or its mortgagee may deem advisable.  Tenant shall have no right to any
      proceeds from such policies. Landlord shall not carry any insurance on any
      of
      Tenant’s property, and shall not be obligated to repair or replace any of
      Tenant’s property.

    

    6.4

    Changes
      by Landlord.  Landlord may at any time make any
      changes, additions, improvements, repairs or replacements to the Property,
      including the Common Areas, that it considers desirable.  In so doing,
      Landlord may use or temporarily close or reconfigure any of the Common Areas,
      or
      permanently change their configuration.  Landlord shall use reasonable
      efforts to minimize interference with Tenant’s normal activities, but no such
      interference shall constitute constructive eviction or give rise to any
      abatement of rent or liability of Landlord to Tenant.  Landlord may also
      discontinue any facilities or services provided as part of the Common Areas
      or
      as common facilities if such areas or facilities are not described in Building
      services in Exhibit B.

    

    6.5

     Failure
      to Provide Services and Repairs.  Landlord
      shall not be liable for any failure to perform any act or provide any service
      required hereunder unless Tenant shall have given written notice of such
      failure, and provided such failure is susceptible to being cured and such
      failure continues for at least thirty days thereafter.  Notwithstanding the
      foregoing, in the event of interruption or termination of utility services
      to
      the Premises or the Building or Landlord’s failure to provide any other required
      service hereunder, which failure is caused by factors beyond Landlord’s
      reasonable control, then Landlord shall not be liable to Tenant in any such
      event, and such event shall not constitute constructive eviction or give rise
      to
      any rental abatement or reduction or any other liability of Landlord to Tenant.
       Tenant hereby waives any right to make repairs or provide maintenance at
      Landlord’s expense under any law or ordinance.  If because of such
      interruption or termination of services required to be provided by Landlord
      hereunder the Premises remain untenantable for reasons other than (i) force
      majeure or (ii) any act or omission of Tenant or its employees, agents,
      contractors or invitees for a period of more than ten (10) consecutive business
      days, rent shall thereafter abate on an equitable basis during the period of
      untenantability. 

    

    7.

    Alterations.

    

    Tenant
      shall not make or permit to be made any alterations,
      additions, modifications or improvements to the Premises (including without
      limitation painting and carpeting) without the prior written consent of
      Landlord, which consent will not be unreasonably withheld, provided that such
      alterations, additions, modifications or improvements are not structural or
      involve Building systems in which case Landlord’s consent may be withheld in
      Landlord’s sole discretion.  If Tenant desires to make any such
      alterations, additions, modifications or improvements, a duplicate set of plans
      for the same shall first be submitted to and approved by Landlord and Landlord
      shall have the right to request reasonable revisions and corrections to the
      plans, all of which corrections and revisions shall be incorporated by Tenant
      (with revised duplicate sets delivered to Landlord).  All such work shall
      be done by Tenant, at its own expense, and Tenant agrees that all such work
      shall be done in a good and workmanlike manner (Landlord having the right to
      approve all contractors, all of whom shall be bonded and properly licensed)
      in
      accordance with the approved plans therefor and all applicable Requirements,
      that the structural integrity of the Building shall not be impaired, that no
      liens shall attach to the Premises or the Property by reason therefor, and
      that
      Tenant will secure all necessary permits pertaining to the aforementioned
      alterations, additions, modifications or improvements.  Tenant shall
      reimburse Landlord upon demand therefor for all reasonable costs and expenses
      incurred by Landlord in connection with its review of such plans and the
      inspection of the work contemplated thereby.  Tenant has no authority or
      power, express or implied, to create or cause to be created or to consent to
      any
      lien, charge or encumbrance of any kind against the Premises or the Property.
       Tenant shall pay before delinquency all costs for work done or caused to
      be done by Tenant in the Premises which could result in any lien or encumbrance
      on Landlord’s interest in the Property or any part thereof, shall keep the title
      to the Property and every part thereof free and clear of any lien or encumbrance
      with respect to such work and shall indemnify and hold harmless Landlord against
      any claim, loss, lien, cost, demand or legal or other expense, whether in
      respect of any lien, injury to person or property (including the Building)
      or
      otherwise, arising out of the work performed or to be performed at the Premises
      or the supply of material, services or labor for such work.  Tenant shall
      immediately notify Landlord of any such lien, claim of lien or other action
      of
      which it has knowledge and which affects the title to the Property or any part
      thereof and shall cause the same to be removed within ten (10) days, failing
      which Landlord may take such action as Landlord deems necessary to remove the
      same and the cost thereof (including reasonable attorneys’ fees) shall be
      immediately due and payable by Tenant to Landlord.  All alterations,
      additions, improvements and fixtures (other than Tenant’s personal property,
      provided the same are installed at no cost or expense to Landlord) which may
      be
      made or installed by either party upon the Premises shall be and remain the
      property of Landlord and shall remain upon and be surrendered with the Premises,
      unless Landlord requests their removal, in which event Tenant shall remove
      the
      same and restore the Premises to its original condition, taking into account
      normal wear and tear, at Tenant’s sole cost and expense and Tenant shall pay the
      entire cost of such removal.  If Tenant fails to remove such property and
      restore the Premises as aforesaid, Landlord may do so and Tenant shall pay
      the
      entire cost thereof to Landlord within ten (10) days after Tenant’s receipt of
      Landlord’s written demand therefor.  In connection with the installation of
      any alterations, additions, modifications and improvements, including without
      limitation, any described in Article 2 hereof, Tenant shall be responsible
      for
      and pay any construction management fee charged by the property manager,
      provided the fee does not exceed ten percent (10%) of the sum of hard costs,
      soft costs and permit fees of any such installation of alterations, additions,
      modifications or improvements; provided, however, that the construction
      management fee shall not exceed five percent (5%) with respect to the initial
      Tenant Improvements described in Section 2.4.

    

    8.

    Hazardous
      Substances and Environmental Issues.

    

    8.1

    Hazardous
      Substances.  Tenant (a) shall not use, process,
      release, discharge, generate, treat, store, transport or dispose of any
      Hazardous Substances on, in, under or through the Premises or Property (other
      than substances necessary for the proper operation of business machines
      (e.g., photocopying machines and printers)), and (b) shall prohibit its
      employees, licensees, subtenants, invitees and third party contractors from
      using, processing, releasing, discharging, generating, treating, storing or
      disposing of any Hazardous Substances on, in, under or through the Premises
      or
      Property, in either case in quantities or concentrations or in a manner which
      would violate any applicable Requirement.  In addition to any other
      obligation or liability that Tenant may have hereunder or under applicable
      law,
      if Tenant or any of Tenant’s employees, licensees, subtenants, invitees or third
      party contractors uses, processes, releases, discharges, treats, generates,
      stores, transports or disposes of any Hazardous Substance on, in, under or
      through the Premises or the Property in violation of the terms of this Lease
      or
      applicable law, then Tenant upon discovering same or upon notice from Landlord
      or any governmental authority shall immediately remove such Hazardous Substance
      from the Premises and the Property at Tenant’s sole cost and expense in
      accordance with all applicable Requirements.  Tenant hereby indemnifies and
      holds Landlord harmless from any loss, cost, claim, damage or expense including
      reasonable attorneys’ fees arising out of a breach by Tenant of its obligations
      under this Section, which indemnification obligation shall survive the
      expiration or termination of this Lease.  For purposes hereof the term
“Hazardous Substances” shall mean any and all substances (whether liquid, solid
      or gas) defined, listed or otherwise classified as pollutants, hazardous wastes,
      hazardous substances, hazardous materials, extremely hazardous wastes, or words
      or terms of similar regulatory effect under any present or future Requirement
      or
      that may have a negative impact on human health, safety or the environment,
      including, but not limited to, petroleum and petroleum products, asbestos and
      asbestos-containing materials, polychlorinated biphenyls, lead, lead-based
      paints, radon, radioactive materials, flammables and explosives.  

    

    8.2

    Conservation
      and Environmental Policies and Programs.  Tenant
      shall comply with all conservation and environmental protection programs and
      policies implemented by Landlord to comply with any mandatory or reasonable
      voluntary conservation or environmental protection program or policy promulgated
      by any governmental or quasi-governmental authority.  Landlord shall have
      no liability to Tenant and Tenant shall not, except as expressly provided in
      the
      last sentence of Section 6.5 above, be entitled to any rebate or offset against
      Rent nor shall the same constitute constructive eviction if Landlord is unable
      to provide any of the services provided for in Article 6 because of Landlord’s
      compliance with any such mandatory program or policy. 

    

    9.

    Insurance.

    

    9.1

    Fire
      Insurance.  Tenant agrees, in addition to the provisions
      of Article 8, that it will not do anything that will cause Landlord’s insurance
      against loss by fire or other hazards, as well as public liability insurance,
      to
      be canceled or the rates thereof increased or that will prevent Landlord from
      procuring same in acceptable companies and at standard rates.  Tenant will
      further do everything reasonably possible and consistent with the conduct of
      Tenant’s business to obtain the lowest possible rates for insurance on the
      Premises.  If, however, the cost to Landlord of obtaining insurance on the
      Premises (or the Building in which the Premises are located) is increased due
      to
      the Tenant’s operations during the occupancy thereof, Tenant agrees to pay,
      promptly upon demand, as additional rental, any such increase and such activity
      shall, at Landlord’s option constitute a Default hereunder.

    

    9.2

    Tenant’s
      Insurance. During the Term, Tenant shall obtain and
      maintain in force at Tenant’s sole cost and expense the following
      insurance:

    

    9.2.1

    Casualty
      Insurance.  Fire and Extended Coverage in the form
      of an “All Risk of Physical Loss” policy with extended coverage endorsement,
      including vandalism, malicious mischief, water damage, sprinkler damage,
      earthquake and flood coverage, and any other endorsement required by the holder
      of any fee or leasehold mortgage, in an amount equal to full replacement value,
      at the time of loss, of Tenant’s personal property, leasehold improvements and
      trade fixtures located at the Premises from time to time as well as alterations
      and improvements made by the Tenant.  Such amount shall provide for
      replacement cost and shall be subject to a deductible amount no greater than
      that reasonably acceptable to Landlord.  Landlord agrees that a deductible
      amount of Ten Thousand Dollars ($10,000) is acceptable to Landlord.
 Notwithstanding the foregoing, Tenant shall not be required to carry
      earthquake or flood insurance unless any lender holding a mortgage or deed
      of
      trust on the Building requires earthquake or flood insurance or such insurance
      is generally being required by landlords leasing space in the Washington, D.C.
      metropolitan area.

    

    9.2.2

    Liability
      Insurance.  Commercial General Liability Insurance
      on an “occurrence” basis for the benefit of Landlord, Agent (hereinafter
      defined) and Landlord’s property management company(ies) (if other than Agent)
      and any mortgagee as additional insureds against claims for “personal injury”
liability, including (without limitation) bodily injury, death or property
      damage liability with a limit of not less than One Million Dollars ($1,000,000)
      in the event of “personal injury” including death to any number of persons or of
      damage to property arising out of any one “occurrence” and Two Million Dollars
      ($2,000,000) aggregate;  any such insurance may be furnished under an
“umbrella” policy with Landlord’s prior written consent, which shall not be
      unreasonably withheld so long as the amount of insurance covering the Premises
      is not reduced by losses occurring at other locations.  Such amount shall
      be subject to a deductible amount no greater than that reasonably acceptable
      to
      Landlord.  Landlord agrees that a deductible amount of Ten Thousand Dollars
      ($10,000) is acceptable to Landlord.  The policy shall insure performance
      by Tenant of the indemnity provisions of Section 9.5.  The limits of any
      such insurance shall not, however, limit the liability of Tenant under this
      Lease.  

    

    9.2.3

    Worker’s
      Compensation.  Worker’s compensation insurance
      (including employees’ liability insurance) in the amount covering all employees
      of Tenant employed at or performing services at the Premises, in order to
      provide the statutory benefits required by the laws of the Commonwealth of
      Virginia.

    

    9.2.4

    Business
      Interruption.  Business interruption insurance,
      providing in the event of damage or destruction of the Premises an amount
      sufficient to sustain Tenant for a period of not less than one year for: (a)
      the
      net profit that would have been realized had the business continued; and (b)
      such fixed charges and expenses as must necessarily continue during a total
      or
      partial suspension of business to the extent to which they would have been
      incurred had no business interruption occurred, including, but not limited
      to,
      interest on indebtedness, charges under noncancellable contracts, charges for
      advertising, legal or other professional services, taxes and rents that may
      still continue, trade association dues, insurance premiums and depreciation.
       With respect to the initially named Tenant only (E-IOR Technologies,
      Inc.), this Section 9.2.4 shall be waived. 

    

    9.2.5

    Other
      Insurance.  Such other insurance as Landlord or any
      mortgagee may reasonably require including, without limitation, builder’s risk
      insurance during the course of any improvements, alterations, additions or
      modifications to the Premises other than those completed by the Landlord under
      Sections 2.3 and 2.4.1 above.

    

    9.3

    Insurance
      Policies and Insurers.  All insurance policies
      required to be obtained and maintained by Tenant under this Lease shall be
      issued by insurance companies authorized to do business in the Commonwealth
      of
      Virginia and with a rating of at least “A” in A.M. Best’s Key Rating Guide and
      at least “X” in A.M. Best’s Financial Rating Guide, shall be written as primary
      policies and not contributing with or in excess of any coverage which Landlord
      may carry, shall provide that the policy may not be canceled or amended or
      the
      coverage thereunder reduced unless Landlord and each other party designated
      as
      an additional insured or loss payee thereunder shall have received thirty (30)
      days prior written notice, shall contain a provision or have the effect that
      Landlord and any other parties in interest shall be entitled to recover under
      those policies for any covered loss occasioned to them, notwithstanding any
      act
      or omission of Tenant or any other named insured and shall otherwise be in
      form
      and content reasonably satisfactory to Landlord.  Tenant shall furnish to
      Landlord, prior to the Commencement Date, and within thirty (30) days prior
      to
      the expiration of each such policy, a certificate of insurance issued by the
      insurance carrier of each policy of insurance carried by Tenant pursuant hereto,
      reflecting the coverages required by this Article 9, and a copy of each
      insurance policy.  Landlord, its successors and assigns, Landlord’s
      property management company(ies) and each nominee of Landlord holding any
      interest in the Premises shall be designated as an additional insured and as
      a
      loss payee, as applicable, under each policy of insurance (other than those
      for
      worker’s compensation) maintained by Tenant pursuant to this Article 9.
 The premiums on any policy which Tenant is required to carry pursuant to
      this Article 9 shall be paid when due.  Upon payment of such premiums,
      reasonable evidence of payment shall be provided to Landlord.  Tenant shall
      immediately notify Landlord in the event that any of its insurance carriers
      cancel or modify any policy of insurance and shall also notify Landlord at
      least
      thirty (30) days prior to changing insurance carriers or the modification or
      cancellation of any policy; provided, however, that the notification hereinabove
      required shall not relieve Tenant of its obligation to maintain continuously
      in
      effect the types and amounts of insurance specified in this Article 9.  If
      Tenant fails to provide evidence reasonably satisfactory to Landlord of Tenant’s
      timely compliance with the requirements of this Article 9, Landlord shall have
      the right, after written notice to Tenant, to place any and all of the insurance
      coverages set forth above and Tenant agrees to reimburse Landlord immediately
      upon demand, as Additional Rent, Landlord’s cost of such coverages.  From
      time to time, but in no event more frequently than once in any three-year
      period, Landlord shall have the right to reasonably adjust the dollar limits
      of
      coverage set forth in this Article 9 consistent with market
      recommendations.

    

    

    9.4

    Waiver
      of Subrogation.  

    

    9.4.1

    Release.
 Subject
      to the provisions of Subsection 9.4.2,
      Landlord and Tenant (on behalf of themselves and their respective agents,
      employees, third party contractors, subtenants, licensees, invitees and
      assignees) each release the other with respect to and agree that the other
      shall
      not be liable for any business interruption or any loss or damage to property
      or
      injury to or death of persons occurring on the Premises, in the Building or
      on
      adjoining property or in any manner arising out of or connected with Tenant’s
      use of the Premises, whether or not caused by the negligence or other fault
      of
      Landlord or Tenant or any of their respective agents, employees, third party
      contractors, subtenants, licensees, invitees or assignees; in addition, however,
      that Tenant (and such other listed related parties) hereby also release Agent
      and Landlord’s property management company(ies) (if other than Agent) and agree
      that Agent and Landlord’s property management company(ies) (if other than Agent)
      shall not be liable in the same manner as Landlord.

    

    9.4.2

    Insurance
      Coverage.  The release and waiver contained in
      Subsection 9.4.1 shall apply only to the extent that such business interruption,
      loss or damage to property, or injury to or death of persons is covered by,
      or
      required hereunder to be covered by insurance (excluding liability insurance),
      regardless of whether such insurance is payable or protects the Landlord (and
      Agent and Landlord’s property management company(ies) if other than Agent) or
      Tenant or both.  Nothing in this Section 9.4 shall be construed to impose
      any other or greater liability upon either the Landlord (and Agent and
      Landlord’s property management company(ies) if other than Agent) or Tenant then
      would have existed in absence of this Subsection.

    

    9.4.3

    No
      Effect.  The release and waiver contained in Subsection
      9.4.1 shall be in effect only so long as the applicable insurance policies
      contain a clause to the effect that such release and waiver will not affect
      the
      right of the insured to recover under such policies.  Such clauses shall be
      obtained by the parties in policies to be obtained by them whenever possible.
      

    

    9.5

    Indemnity.
 Tenant
      shall indemnify, hold harmless and defend
      Landlord, and Agent and Landlord’s property management company(ies) if other
      than Agent, from and against any and all claims, demands, causes of action,
      loss, liability, costs or expenses (including, without limitation, reasonable
      attorneys’ fees and costs) arising out of, connected with or incidental to:
      Tenant’s use and occupancy of the Premises or the business conducted by Tenant
      therein; or any act or omission by Tenant or any of Tenant’s agents, employees,
      third party contractors, subtenants, licensees, invitees or assignees; or any
      Default by Tenant under this Lease.  Tenant’s obligations under this
      Section 9.5 shall not apply to claims, demands, causes of action, loss,
      liability, costs or expenses to the extent resulting from the gross negligence
      or intentional misconduct of Landlord or its agents, employees or third party
      contractors.  Tenant’s obligations under this Section 9.5 as well as under
      any other indemnity provision set forth in this Lease shall survive the
      termination or expiration of this Lease.

    

    10.

    Permits
      - Compliance with Laws.

    

    10.1

    Permits.
 Excluding
      the necessary building permits for the
      Tenant Improvements being performed under the control of the Landlord per
      Section 2 above, Tenant shall, at its own expense, promptly obtain from the
      appropriate governmental authorities and maintain in full force and effect
      during the Term of this Lease any and all permits, licenses and the like
      required to permit Tenant to occupy the Premises and conduct its business for
      the purposes herein stated. Tenant’s failure to satisfy this requirement shall
      not relieve the Tenant of its liability for all Rent from the Commencement
      Date.

    

    10.2

    Compliance
      with Laws.  Tenant shall continuously comply with
      and cause its employees, agents, contractors, invitees and licensees to comply
      with all Requirements applicable to Tenant’s use and occupancy of the Premises
      and the Common Areas.

    

    11.

    Assignment
      and Subletting.

    

    Tenant
      agrees that it will not, by agreement, operation of law or
      otherwise, without Landlord’s prior written consent, (i) assign, transfer, or
      encumber the Lease, in whole or in part, or (ii) sublet, license or otherwise
      permit others to occupy the Premises, in whole or in part (all of the foregoing
      in clauses (i) and (ii) being referred to as a “Transfer”).  Landlord shall
      base its decision on consent to a Transfer upon, among other factors, the
      credit-worthiness, use, and reputation of the proposed transferee, assignee,
      sublessee, licensee or other occupant (a “Transferee”), and Landlord agrees that
      it will not arbitrarily withhold its consent.  No Transfer shall relieve or
      release Tenant from any liability or obligation under this Lease (and the
      transferring Tenant shall continue to have primary liability under this Lease,
      jointly and severally with the Transferee), nor shall any Transfer relieve
      or
      release any guarantor from any liability or obligation under any guaranty of
      this Lease.  Tenant hereby acknowledges that among other reasons and
      factors, Landlord's disapproval of any proposed Transfer shall be deemed valid
      and final if based upon any or all of the following factors:  (i) the
      proposed Transfer would result in more than two subleases of portions of the
      Premises being in effect at any one time during the Term, or would result in
      any
      sublease premises or the remainder of the Premises (i.e., that not subleased)
      not having direct access to a Building common area corridor in manner which
      complies with applicable code; (ii) the net effective rent payable by the
      Transferee (adjusted on a rentable square foot basis) is less than the net
      effective rent then being quoted by Landlord for new leases in the Building
      for
      comparable size space for a comparable period of time; (iii) the proposed
      Transferee is an existing tenant of the Building or is negotiating with
      Landlord; (iv) the proposed Transferee is a governmental entity; (v) the portion
      of the Premises to be sublet or assigned is irregular in shape with inadequate
      means of ingress and egress; (vi) the use of the Premises by the Transferee
      (A)
      is not permitted by the use provisions hereof, or (B) violates any exclusive
      use
      granted by Landlord to another tenant in the Building (to the extent such
      exclusive is disclosed to Tenant); (vii) the Transfer would result in
      significant increase in the use of the parking areas or Common Areas by the
      Transferee's employees or visitors, and/or significantly increase the demand
      upon utilities and services to be provided by Landlord to the Premises; (viii)
      the Transferee does not have the financial capability to fulfill the obligations
      imposed by the Transfer; (ix) the Transferee is not in Landlord's opinion of
      reputable or good character or consistent with Landlord's desired tenant mix;
      or
      (x) the Transferee is a real estate developer or landlord or is acting directly
      or indirectly on behalf of a real estate developer or landlord.  Tenant
      further agrees that if it intends to Transfer the entire Premises, it will
      first
      notify Landlord in writing and Landlord shall have fifteen (15) days to notify
      Tenant that Landlord, at its option may accept a surrender of the Premises,
      in
      which event Landlord shall release Tenant from any further liability under
      this
      Lease from and after the date the Premises are surrendered.  Tenant agrees
      to pay Landlord a minimum fee of $500.00, plus any reasonable out-of-pocket
      costs incurred by Landlord, for services rendered in respect to each request
      for
      consent to a Transfer.  Any Transfer without Landlord’s prior written
      consent shall be a Default under this Lease, and at Landlord’s sole option, be
      deemed void.  Any Transfer to which Landlord consents shall not be
      effective until the Transferee executes an acknowledgement of Landlord’s consent
      to the Transfer, assignment or subletting on Landlord’s standard form, and
      unless Landlord’s otherwise agrees, any such Transfer shall be on Landlord’s
      standard form therefor.  Consent to any Transfer shall not be deemed a
      consent to any subsequent Transfer.  In the event of any Transfer (provided
      Landlord has not accepted a surrender of the Premises), any rent that Tenant
      receives in excess of the Rent per Article 3 shall be split 50/50 between
      Landlord and Tenant.  For the purposes of the foregoing, any transfer,
      direct or indirect (e.g., through transfer of ownership interests in the
      ownership entity or further upstream entity) of the ownership interests in
      Tenant (whether stock, partnership interests or membership interests or other),
      whether in one or more successive transfers, of either (i) a controlling
      interest, or (ii) more than twenty-five percent (25%) interest, shall be deemed
      an assignment.  

    

    12.

    Subordination.

    

    Tenant
      accepts this Lease, and the tenancy created hereunder,
      subject and subordinate to any leases, mortgages, deeds of trust, leasehold
      mortgages or other security interests now or hereafter a lien upon or affecting
      the Building or the Property or any part thereof.  Tenant shall, at any
      time hereafter, within ten (10) days following request therefor, execute any
      instruments, leases or other documents that may be required by any ground
      lessor, mortgage, mortgagee, deed of trust, beneficiary, trustee or underlying
      owner or Landlord hereunder to confirm Tenant’s subordination of its interest
      hereunder to the lien of any such mortgage or mortgages, deed or deeds of trust
      or underlying lease, and the failure of Tenant to execute any such instruments,
      leases or documents shall constitute an immediate Default hereunder.

    

    13.

    Attornment.

    

    Tenant
      agrees that upon any termination of Landlord’s interest in
      the Premises, Tenant will, upon request, attorn to the person or organization
      then holding title to the Property or Landlord’s prior interest therein (the
“Successor”) and to all subsequent Successors, and shall pay to the Successor
      all rents and other monies required to be paid by the Tenant hereunder and
      perform all of the other terms, covenants, conditions and obligations contained
      in this Lease, and Tenant will execute and deliver to Landlord (and Landlord’s
      mortgagee) and any Successor, such instruments as may be required by such person
      confirming same.  

    

    14.

    Property
      Loss or Damage.

    

    14.1

    Landlord’s
      Responsibility.  Subject to the provisions of
      Section 14.2, Tenant hereby expressly agrees that Landlord (and Agent and
      Landlord’s property management company(ies) if other than Agent) shall not be
      responsible in any manner for any damage or injury to the person or property
      of
      Tenant or any other person or business directly or indirectly caused by (i)
      dampness or water, whether due to a break or leak in any part of the roof,
      heating, or plumbing within the Premises, or in the Building in which the
      Premises are located, no matter how caused; (ii) theft; (iii) fire or other
      casualty; (iv) any other cause whatsoever.

    

    14.2

    Landlord’s
      Liability for Damages.  Landlord shall only be
      liable for actual damages or injury to person or property of Tenant or of any
      other person or business where (i) notice in writing of any defect which
      Landlord is obligated under the terms of this Lease to correct and which caused
      such damage or injury, has been given in sufficient time before the occurrence
      of such damage or injury to have enabled Landlord to correct such defect, and
      (ii) then only if such damage or injury is due to Landlord’s gross negligence in
      performing its obligations hereunder, and (iii) Landlord is not released, deemed
      not liable or indemnified therefrom elsewhere herein.

    

    15.

    Tenant’s
      Failure to Perform.

    

    In
      the event that Tenant fails to do any act or make any payment
      or perform any term or covenant on Tenant’s part required under this Lease or
      otherwise fails to comply herewith, after expiration of any applicable cure
      period, Landlord may (at its option, but without being required to do so)
      immediately, or at any time thereafter and without any further notice, and
      without relieving Tenant of any of its obligations hereunder, perform the same
      on the account that Tenant has failed to do so; provided however, that it is
      understood that the cure period in Section 21 shall not apply with respect
      to
      (x) obligations relating to maintenance of insurance, and removing or bonding
      a
      lien, which shall be governed by Sections 7 and 9 respectively; and (y) repair
      of the Premises or other parts of the Property, in which case Landlord shall
      not
      exercise such right until the expiration of fifteen (15) days’ written notice
      from Landlord (except in the case of an emergency in which case no such notice
      shall be required, and immediate exercise is permitted). If Landlord makes
      any
      expenditures, or incurs any obligations for the payment of money in connection
      therewith, including, but not limited to, attorneys’ fees in instituting
      prosecuting or defending any action or proceeding, such sums paid or obligations
      incurred, with interest at the rate of twelve percent (12%) per annum from
      the
      date Landlord incurs such expense or cost, shall be deemed to be Additional
      Rent
      hereunder and shall be paid by Tenant to Landlord within five (5) days of
      rendition of any bill or statement to Tenant therefor.  All rights given to
      Landlord in this Article shall be in addition to any other rights or remedies
      of
      Landlord herein contained or otherwise available.

    

    16.

    Landlord’s
      Right to Show and Inspect
      Premises.

    

    Tenant
      agrees that Landlord may, within the last nine (9) months
      of the Lease term, display a “For Lease” or “For Sale” sign on the Premises and
      show prospects through the Premises at any reasonable time, with twenty-four
      (24) hours’ prior notice to allow Tenant to arrange for escorted tours.  In
      addition, Landlord may, during any reasonable time or times, before and after
      the Commencement Date, enter upon the Premises, any portion thereof and any
      appurtenance thereto (with men and materials, if required) for the purpose
      of:
      (i) inspecting the same, (ii) making such repairs, replacements or alterations
      which it may be required to perform under the provisions of this Lease or which
      it may deem desirable for the Premises or the Building, including but not
      limited to repairs and improvements to space above, below and/or on the same
      floor as the Premises and/or (iii) performing any other acts required of or
      permitted to Landlord herein or under any applicable Requirement. Landlord
      agrees to give notice prior to any such entry and allow Tenant to escort
      Landlord through the Premises (but only if Tenant is available at the time
      of
      entry and Tenant shall not be obligated to escort Landlord) except that Landlord
      may enter without notice in the case of an emergency.  Tenant shall install
      an intrusion alarm system with motion detectors.  Tenant shall provide
      Landlord with a 24-hour emergency call number so Landlord can contact an
      employee of Tenant to de-activate the intrusion alarm system if after-hours
      emergency access without tripping the intrusion alarm is necessary.
  In making such an entry, Landlord agrees to use reasonable efforts
      to avoid interfering with the regular and usual conduct of Tenant’s business and
      Tenant shall not interfere with the conduct of any such inspection or
      tour.

    

    17.

    Surrender
      at End of Term.

    

    Tenant
      shall vacate the Premises at the expiration or other
      termination of this Lease, and except as otherwise provided, shall remove all
      goods and effects not belonging to Landlord (including without limitation all
      wiring and cabling including those running outside of the Premises), and any
      leasehold alterations, additions, improvements and fixtures to be removed from
      the Premises by Tenant pursuant to the terms of Section 7 hereof, and shall
      surrender possession of the Premises and all fixtures and systems thereof not
      required to be removed, in good repair and good working condition, reasonable
      wear, tear and damage by casualty for which Tenant is not responsible hereunder
      excepted and Tenant shall otherwise comply with Section 7 hereof.  If
      Tenant shall fail to perform any of the foregoing obligations, Landlord is
      hereby expressly authorized to do so on Tenant’s behalf and at Tenant’s sole
      cost and expense, and Landlord may sell such articles on the Premises as
      Landlord in its sole discretion deems saleable, and may dispose of others in
      any
      manner which it chooses.  Tenant shall pay and be liable for any and all
      costs and expenses incurred by Landlord hereunder.  The proceeds of any
      such sale shall be applied toward the expenses thus incurred as well as any
      other outstanding obligations of Tenant under this Lease and Tenant agrees
      to
      pay any remaining balance promptly.

    

    18.

    Holding
      Over.

    

    If
      Tenant shall not immediately surrender possession of the
      Premises at the termination or expiration of this Lease, Tenant shall become
      a
      month-to-month Tenant, at twice the Basic Monthly Rent and Additional Rent
      in
      effect just prior to termination or expiration of this Lease, said rental to
      be
      payable in advance.  Notwithstanding the foregoing, the Landlord shall
      continue to be entitled to re-take possession of the Premises immediately upon
      the expiration of the term hereof or, without notice, at any time prior to
      accepting the rent payment for the next ensuing month , and the Tenant hereby
      agrees that all of the obligations of the Tenant and all rights of the Landlord
      applicable during the term of this Lease shall be equally applicable during
      such
      period of subsequent occupancy, whether or not a month-to-month tenancy shall
      have been created as aforesaid.  Tenant further agrees that it shall be
      liable for any damages suffered by Landlord by reason of Tenant’s failure to
      immediately surrender the Premises.

    

    19.

    Destruction
      - Fire or Other Casualty.

    

    In
      case of partial damage to the Premises by fire or other
      casualty, insured against by Landlord, Tenant shall give immediate notice
      thereof to Landlord, and Landlord, to the extent that insurance proceeds
      respecting such damage are subject to and, in fact, are under the control and
      use of Landlord, shall thereupon cause such damage to all property owned by
      Landlord to be repaired with reasonable speed at the expense of Landlord, due
      allowance being made for reasonable delay which may arise by reason of
      adjustment of loss under insurance policies on the part of Landlord and/or
      Tenant, and for reasonable delay on account of “labor troubles” or any other
      cause beyond Landlord’s control and to the extent that the Premises are rendered
      actually untenantable, the rent shall proportionately abate, unless Tenant
      cannot materially conduct business, in which case the Premises shall be deemed
      untenantable.  Notwithstanding the foregoing, if such partial damage is due
      to the fault or neglect of Tenant or those employing or retaining the services
      of Tenant, or Tenant’s servants, employees, agents, contractors, licensees,
      invitees or visitors, or to the extent that insurance proceeds respecting such
      damage are not subject to and, in fact, are not under the control and use of
      Landlord, the damage shall be repaired by Landlord at Tenant’s expense and there
      shall be no apportionment or abatement of rent.  In the event the damage
      shall be so extensive to the whole Building as to render it uneconomical, in
      Landlord’s opinion, to restore for the use of Tenant, as specified in Article 5
      hereof, or Landlord shall decide not to repair or rebuild the Building, then
      Landlord may elect to terminate this Lease upon written notice to Tenant and
      this Lease shall expire by lapse of time upon the third day after such notice
      is
      mailed, and Tenant shall thereupon vacate the Premises and surrender the same
      to
      Landlord, but such termination shall not release Tenant from any liability
      to
      Landlord arising from such damage or from any breach of the obligations imposed
      on Tenant hereunder or any other obligations which expressly survive the
      termination of this Lease.  In no event shall Landlord have any obligation
      to repair or restore any of Tenant’s improvements or property provided, further,
      that in the event Landlord repairs or restores the Premises, Tenant shall
      promptly restore all of Tenant’s improvements, fixtures, equipment and other
      property damaged in such casualty.  The provisions of any statute causing a
      Lease termination or otherwise granting a party the right to terminate the
      Lease
      by reason of fire or other casualty are hereby waived and superceded by this
      Section 19.

    Eminent
      Domain.

    

    If
      the entire Premises shall be substantially taken (either
      temporarily or permanently) for public purposes, or in the event Landlord shall
      convey or lease the property to any public authority in settlement of a threat
      of condemnation or taking, the rent shall be adjusted to the date of such taking
      or leasing or conveyance, and this Lease shall thereupon terminate.  If
      only a portion of the Premises shall be so taken, leased or condemned as a
      result of such partial taking, and Tenant is reasonably able to use the
      remainder of the Premises for the purposes intended hereunder, then this Lease
      shall not terminate, but, effective as of the date of such taking, leasing
      or
      condemnation, the rent hereunder shall be abated in an amount thereof
      proportionate to the area of the Premises so taken, leased or condemned.
 If, following such partial taking, Tenant shall not be reasonably able to
      use the remainder of the Premises for the purposes intended hereunder, then
      this
      Lease shall terminate as if the entire Premises had been taken, leased or
      condemned.  In the event of a taking, lease or condemnation as described in
      this Article, whether or not there is a termination hereunder, Tenant shall
      have
      no claim against Landlord other than for a rental abatement to the extent
      provided above, and Tenant shall not be entitled to any portion of any amount
      that may be awarded as damages or paid as a result of or in settlement of such
      proceedings or threat.

      (10) days after written notice thereof from Landlord to Tenant, or if the nature
      of the Tenant’s default cannot be cured in such ten (10) day period, if Tenant
      fails to commence such cure within said ten (10) day period  or thereafter
      fails to diligently prosecute such cure to comple­tion, within thirty (30)
      days of the original notice.

      making by Tenant or any guarantor of this
      Lease of any general assignment or general arrangement for the benefit of
      creditors, filing by or against Tenant or any such guarantor of a petition
      to
      have Tenant or such guarantor adjudged a bankrupt or a petition for
      reorganization or arrangement under any law relating to bankruptcy (unless

      dismissed within sixty (60) days), the appointment of a Trustee or receiver

 Upon
      the occurrence of a Default and at any time
      thereafter, in addition to any other rights and remedies Landlord may have
      under
      this Lease or at law or in equity, whether or not Tenant abandons the Premises,
      Landlord shall have the option, in its sole discretion, to do any one or more
      of
      the following: (i) terminate this Lease by any lawful means in which case Tenant
      shall immediately surrender possession of the Premises to Landlord, (ii)
      re-enter the Premises, without terminating this Lease, and remove any property
      from the Premises, in which case Landlord shall be entitled to enforce all
      of
      Landlord’s rights and remedies under this Lease including the right to recover
      all Rent and other amounts as they become due and (iii) pursue any other or
      additional right or remedy now or hereafter available to Landlord under the
      law
      of the jurisdiction where the Building is located.  No re-entry or
      re-taking of possession of the Premises by Landlord hereunder or other action
      on
      Landlord’s part shall be construed as an election to terminate this Lease unless
      a written notice of such intention is given to Tenant or unless the termination
      thereof is decreed by a court of competent jurisdiction.  Landlord’s
      election not to terminate this Lease pursuant to clause (i) above shall not
      preclude Landlord from subsequently electing to terminate this Lease or pursuing
      any of its other remedies. 

    

    21.2.1

    Reletting
      of Premises.  Whether or not this Lease or Tenant’s
      right of possession is terminated following such Default, Landlord may relet
      the
      Premises or any part thereof, alone or together with other premises, for such
      term or terms (which may be greater or less than the period which otherwise
      would have constituted the balance of the Term) and on such terms and conditions
      (which may include concessions of free rent and alterations of the Premises)
      as
      Landlord, in its sole discretion, may deem necessary or appropriate, but
      Landlord shall not be liable for, nor shall Tenant’s obligations hereunder be
      diminished by reason of, any failure by Landlord to relet the Premises or any
      failure by Landlord to collect any rent due upon such reletting; provided,
      however, that notwithstanding the foregoing, in the event that Tenant presents
      one or more prospective tenants to Landlord, Landlord shall consider in good
      faith reletting the Premises or any portion thereof to any such prospective
      tenants, provided such tenants are, among other things, of the kind, type,
      reputation, creditworthiness and quality typically found in similar
      buildings.

    

    21.2.2

    Damages.
 Whether
      or not this Lease or Tenant’s right of
      possession is terminated following such Default, Tenant nevertheless shall
      remain liable for:

    

    (a)

    all
      Basic Monthly Rent and Additional Rent (including, without
      limitation, all damages sustained by Landlord by reason of the Default) which
      have become due until the expiration of the Term or sooner termination of the
      Lease (less the amount of rental, if any, that Landlord actually receives during
      such period from others to whom the Premises is rented (other than any
      Additional Rent received by Landlord as a result of any failure of such other
      person to perform any of its obligations to Landlord)), and all costs, fees
      and
      expenses (including, without limitation, reasonable attorneys’ fees, brokerage
      fees, and expenses incurred in placing the Premises in first-class rentable
      condition including, without limitation, alterations of the Premises), incurred
      by Landlord in pursuit of its remedies hereunder or in renting the Premises
      to
      others from time to time (all such Basic Monthly Rent, Additional Rent, damages,
      costs, fees and expenses are herein called “Accrued Damages”); and

    

    (b)

    additional
      damages commencing as of the day following the last day
      Accrued Damages are applicable (herein called “Termination Damages”,
      which, at the election of Landlord, shall be either (provided that Landlord
      may
      initially elect under Section 21.2.2(b)(i),  and subsequently at any time
      elect under Section 21.2.2(b)(ii) for the remaining applicable period at the
      time of such election):

    

    (i)

    An
      amount equal to the Basic Monthly Rent and Additional Rent that
      would have become due during the remainder of the Term, and, to the extent
      not
      included in Accrued Damages above, all costs, fees and expenses (including,
      without limitation, reasonable attorneys’ fees, brokerage fees, and expenses
      incurred in placing the Premises in first-class rentable condition including,
      without limitation, alterations of the Premises), incurred by Landlord in
      pursuit of its remedies hereunder or in renting the Premises to others from
      time
      to time, less the amount of rental, if any, that Landlord actually receives
      during such period from others to whom the Premises is rented (other than any
      Additional Rent received by Landlord as a result of any failure of such other
      person to perform any of its obligations to Landlord), in which case such
      Termination Damages shall be computed and payable in monthly installments,
      in
      advance, on the first day of each calendar month following the last day Accrued
      Damages are applicable and continuing until the date on which the Term would
      have expired but for Tenant’s Default.  Separate suits or actions may be
      brought to collect any such Termination Damages for any month or months, and
      such separate suits or action shall not in any manner prejudice the right of
      Landlord to collect any Termination Damages for any subsequent month or months
      by similar proceedings, or Landlord may defer any suits or actions until after
      the expiration of the Term; or

    

    (ii)

    The
      amount determined by subtracting (A) the present value (as of
      the first date Termination Damages are applicable) of the fair rental value
      of
      the Premises for the remainder of the Term (in determining such fair rental
      value, the Basic Monthly Rent and operating cost charges then being paid by
      tenants for comparable space in comparable buildings in equally desirable
      locations in the Fredericksburg regional area shall be considered), from (B)
      the
      present value (as of the first date Termination Damages are applicable) of
      all
      Basic Monthly Rent and Additional Rent that would have become due during the
      remainder of the Term (with such present values being determined using a
      discount rate of eight percent (8%) per annum), which Termination Damages shall
      be payable to Landlord in one lump sum on demand.  For this purpose,
      Additional Rent shall be calculated on the basis that Tenant’s Proportionate
      Share of increases in Operating Expenses and Taxes would increase at the rate
      such expenses have generally increased in the Fredericksburg regional area
      for
      comparable Buildings during the preceding five (5) years, as reasonably
      determined by Landlord.

    

    21.2.3

    Possession
      of Premises.  Whether or not this Lease is
      terminated by reason of Tenant’s Default, Landlord may immediately or at any
      time after the occurrence of a Default reenter and take possession of the
      Premises, either by summary dispossess proceedings, an action for ejectment
      or
      by any other suitable action or proceeding at law or in equity, and the
      provisions of this Article 21 shall operate as a notice to quit.  Tenant
      hereby expressly waives the right to receive any other notice to quit or of
      Landlord’s intention to reenter the Premises.

    

    21.2.4

    Cumulative
      Remedies.  Each right and remedy of Landlord
      provided for in this Lease and each right or remedy now or hereafter existing
      at
      law or in equity or by statute or otherwise shall be cumulative.  The
      exercise or beginning the exercise of any one or more of the rights or remedies
      provided for in this Lease or now or hereafter existing at law or in equity
      or
      otherwise shall not preclude the simultaneous or later exercise of any or all
      other rights or remedies provided for in this Lease or now or hereafter existing
      at law or in equity or otherwise. 

    

    21.2.5

    Eviction
      of Tenant.  Tenant hereby expressly waives any and
      all right of redemption granted by or under any present or future law if Tenant
      is evicted or dispossessed for any cause or if Landlord obtains possession
      of
      the Premises by reason of the violation by Tenant of any of the covenants or
      conditions of this Lease or otherwise.  In addition, Tenant hereby
      expressly waives any and all rights to bring any action whatsoever against
      any
      tenant taking possession after Tenant has been dispossessed or evicted hereunder
      or to make any such tenant a party to any action brought by Tenant against
      Landlord.

    

    21.3

    Landlord
      Default.  Landlord shall not be in default unless
      Landlord fails to perform obligations required of Landlord within a reasonable
      time, but in no event, sooner than ten (10) days after written notice by Tenant
      to Landlord specifying wherein Landlord has failed to perform such obligations;
      provided, however, that if the nature of the Landlord’s obligation is such that
      more than ten (10) days is required for performance, then Landlord shall not
      be
      in default if Landlord commences performance within such ten (10) days and
      thereafter diligently prosecutes the same to completion.

    

    21.4

    Agent’s
      Authority.  While the Agent shall be collecting the
      rentals due from the Tenant, it is hereby authorized by the Landlord to expend
      such sums as may be reasonably necessary in connection with the enforcement
      of
      payment of rental and the securing or possession of the Premises in case of
      Tenant’s default.  All such sums expended by the Agent or the Landlord
      shall be payable by the Tenant as Additional Rent promptly upon demand therefor.
      The Landlord agrees to pay the Agent any of such expenses not so reimbursed
      promptly upon demand.

    

    22.

    Several
      Liability.

    

    If
      the Tenant shall be one or more individuals, corporations or
      other entities, whether or not operating as a partnership or joint venture,
      then
      each such individual, corporation, entity, joint venture or partner shall be
      deemed to be jointly and severely liable for the payment of the entire rent
      and
      other payments specified herein and all other duties and obligations of the
      Tenant hereunder.

    

    23.

    Estoppel
      Certificates.

    

    Tenant
      agrees at any time and from time to time, within ten (10)
      days following a request therefor, to execute, acknowledge and deliver to
      Landlord and/or Landlord’s mortgagee a statement in writing certifying that this
      Lease is unmodified and in full force and effect (or if there have been
      modifications, that the same is in full force and effect as modified and stating
      the modifications) and the dates to which the rent and other charges have been
      paid in advance, if any, and stating whether or not, to the best knowledge
      of
      the signer of such certificate, Landlord is in default in performance of any
      covenant, agreement or condition contained in this Lease and, if so, specifying
      each such default of which the signer may have knowledge, and such other matters
      as Landlord or mortgagee may reasonably request, it being intended that any
      such
      statement delivered hereunder may be relied upon by Landlord, any mortgagee,
      any
      prospective mortgagee, any purchaser of the Property and any prospective
      purchaser or investor in the Property.  Tenant’s failure to execute and
      deliver any such estoppel certificate within such ten (10)-day period shall
      constitute an immediate Default hereunder.

    

    24.

      of light from any other tenant of the Landlord.  

    

    32.5

    Rules
      and Regulations.  Tenant shall abide by and observe,
      and Landlord shall not arbitrarily enforce, the rules and regulations
      promulgated by Landlord for the operation and maintenance of the Building and
      such changes thereto and such additional reasonable rules and regulations that
      Landlord promulgates from time to time during the Term, so long as such changes
      or additional rules and regulations are not inconsistent with this Lease, do
      not
      restrict the use of the Premises by Tenant for the uses permitted by Article
      5
      and reasonable notice of the changes or additions is given to Tenant.  Such
      rules and regulations, together with any such changes and additions, are called
      the “Rules and Regulations” in this Lease.  The Rules and Regulations in
      effect on the date of this Lease are set forth on Exhibit
      C.

    

    32.6

    Liability
      of Landlord.  Except for insurance proceeds which
      Tenant may be entitled to under this Lease, Tenant agrees to look solely to
      Landlord’s interest in the Building for the satisfaction of any right or remedy
      of Tenant for the collection of a judgment (or other judicial process) requiring
      the payment of money by Landlord in the event of any liability by Landlord.
       Except as provided above, no other property or assets of Landlord shall be
      subject to levy, execution, attachment, or other enforcement procedure for
      the
      satisfaction of Tenant’s remedies under or with respect to this Lease, the
      relationship of Landlord and Tenant hereunder, or Tenant’s use and occupancy of
      the Premises, or any other liability of Landlord to Tenant.  In no event
      shall any partner, shareholder, director, officer, employee or agent of Landlord
      incur any personal liability under this Lease and no such liability shall be
      sought, obtained or enforced.

    

    32.7

    Time
      of Essence.  Time is of the essence with respect to each
      and every obligation of Tenant hereunder.

    

    32.8

    Waivers.
 No
      failure by Landlord to insist upon the strict
      performance of or compliance with any covenant or condition of this Lease or
      to
      exercise any right or remedy consequent upon a breach thereof, and no acceptance
      of full or partial Rent during the continuance of any such breach, regardless
      of
      any notation to the contrary accompanying such payment, shall constitute a
      waiver of any such breach or of such covenant or condition. No covenant or
      condition of this Lease to be performed or complied with by either party, and
      no
      breach thereof, shall be waived, altered or modified except by written
      instrument executed by the other party and specifically consenting to the
      particular waiver, alteration or modification.  No waiver of any breach
      shall affect or alter this Lease, but each and every covenant and condition
      of
      this Lease shall continue in full force and effect with respect to any other
      then existing or subsequent breach thereof.  Neither reentry by Landlord in
      accordance with the provisions of this Lease nor acceptance by Landlord of
      keys
      from Tenant shall be considered an acceptance of a surrender of this Lease
      and
      neither of those events shall relieve Tenant of Tenant’s obligations to pay Rent
      and to perform and comply with all of the other covenants and conditions of
      this
      Lease to be performed or complied with by Tenant.  Except as may be
      expressly provided herein, if at all, Tenant has no rights to terminate this
      Lease, and the provisions of any law to the contrary are hereby waived.

    

    32.9

    Attorneys’
Fees.
 If
      legal action is brought with respect to
      this Lease, the substantially prevailing party shall be entitled to
      reimbursement of attorneys’ fees, expert fees and court costs (including those
      on any appeal) from the non-substantially prevailing party.  For the
      purpose of the foregoing, if judgment for any rent is entered in favor of
      Landlord, it shall be deemed that Landlord has substantially prevailed in such
      action.

    

    32.10

    Parking.
 All
      parking areas for the Property shall be under
      the sole and exclusive control of Landlord, and, except to the extent parking
      spaces are leased or offered for lease at the Property, shall be available
      for
      the general use in common by all tenants, their officers, agents, employees
      and
      visitors.  All parking areas are subject to reasonable rules for the use
      thereof which may from time to time be designated by Landlord, including but
      not
      limited to rules designating areas for employee parking, controlling of ingress
      and egress, parking charges, arrangement of spaces and general maintenance
      of
      the parking areas.  Tenant shall be entitled to free unreserved parking at
      a ratio of 4.0 spaces per 1,000 rentable square feet leased.

    

    32.11

    Waiver
      of Notice. Tenant waives statutory notice to quit prior to
      commencement of an action for summary possession for non-payment of rent.

    

    32.12

    No
      Partnership.  Nothing contained in this Lease shall be
      deemed or construed to create a partnership or joint venture between Landlord
      and Tenant, or create any other relationship between the parties hereto other
      than that of landlord and tenant.

    

    32.13

    No
      Representations by Landlord.  Neither Landlord nor any
      agent, representative or employee of Landlord has made any representation or
      promise with respect to the Premises or the Building except as herein expressly
      set forth, and no rights, privileges, easements or licenses are granted to
      or
      acquired by Tenant except as herein expressly set forth. Tenant, by taking
      possession of the Premises, shall accept the same “as is,” and such taking of
      possession shall be conclusive evidence that the Premises and the Building
      are
      in good and satisfactory condition at the time of such taking of
      possession.

    

    32.14

    Brokerage.
 Landlordand
      Tenant each represent that they have
      had no dealing with any real estate broker or other person with respect to
      this
      Lease in any manner except with Grubb & Ellis Company.  Tenant agrees
      to indemnify and hold harmless Landlord from any claims for any fees or
      commissions that are payable to any other broker, individual or entity asserting
      a claim for a fee or commission with respect to this Lease, which
      indemnification obligation shall survive the expiration or termination of this
      Lease.

    

    32.15

    Reserved
      Rights.  Landlord hereby reserves to itself and its
      successors and assigns the following rights (all of which are hereby consented
      to by Tenant):  (i) to change the street address and/or name of the
      Building, (ii) to make such changes, alterations, additions, improvements,
      repairs, or replacements in or to the Building, the Premises, or the Property,
      and the fixtures and equipment thereof, as well as in or to the street
      entrances, halls, passages, elevators, stairways, walkways, driveways, and
      parking areas thereof, as it may deem necessary or desirable, (iii) to change
      the arrangement and/or location of entrances, passageways, doors, doorways,
      corridors, elevators, stairs, toilets, walkways, driveways, and parking areas
      or
      other public parts of the Building or the Property, (iv) to erect, use, and
      maintain shafts, stacks, pipes, conduits, wires, appurtenant fixtures, fan
      rooms, ducts, electric or other utilities, sinks, or other Building facilities
      in and through the Premises, (v) to grant to anyone the exclusive right to
      conduct any particular business or undertaking in the Building.  Landlord
      may exercise any or all of the foregoing rights without being deemed to be
      guilty of an eviction, actual or constructive, or a disturbance or interruption
      of the business of Tenant or Tenant's use or occupancy of the Premises; provided
      that in its exercise of any or all of the foregoing rights, Landlord shall
      not
      unreasonably restrict Tenant's access to the Premises.

    

    32.16

    Counterparts.
 This
      Lease may be executed in several
      counterparts, and all counterparts shall constitute one and the same
      instrument.

    Financials.
 Upon
      request by Landlord from time to time,
      Tenant shall, within ten (10) calendar days, provide to Landlord or to
      Landlord’s lender such financial information certified by Tenant to be true and
      correct as is reasonably necessary for Landlord or Landlord’s lender or any
      prospective lender or purchaser, as the case may be, to evaluate the
      creditworthiness of Tenant (including without limitation, tax returns and a
      statement reflecting all of Tenant’s assets and the nature of Tenant’s interest
      therein).

    

    32.18

    Notice
      to Lender.  In the event of any default by Landlord
      hereunder, Tenant shall, prior to pursuing any right or remedy available to
      Tenant hereunder, send to any lender of which Tenant has notice (the
“Mortgagee”), by certified mail, return receipt requested, a notice specifying
      the default by Landlord, whereupon such Mortgagee shall have the right, but
      not
      the obligation, to cure such default on behalf of Landlord, which cure shall
      be
      accepted by Tenant, and such Mortgagee shall be afforded a reasonable period
      of
      time to do so, including time to obtain possession of the Premises by power
      of
      sale or judicial foreclosure, if such should prove necessary to effect a cure.
       Tenant shall have no right to take any other action as a result of
      Landlord's default unless and until Tenant complies with the provisions of
      this
      paragraph.  Nothing in this paragraph shall create any rights of Tenant
      that are not otherwise expressly provided elsewhere herein.

    

    32.19

    Agent.
 Tenant
      is hereby notified that Landlord has appointed
      Bernstein Management Corporation as the “Agent” hereunder. Landlord has
      authorized said Agent to act for and in the name of the Landlord for any and
      all
      purposes under this Lease and subsequent amendments thereto, and Tenant shall
      direct any and all payments, notices and inquiries of any kind whatsoever
      pursuant to and regarding this Lease to the Agent in accordance with the terms
      set forth above. Landlord reserves the right to substitute any other person,
      firm or corporation as a successor Agent, upon written notice thereof by
      Landlord to Tenant. Tenant hereby acknowledges the authority of any such Agent
      to act for, and in the name of, the Landlord for any and all purposes under
      this
      Lease.  Without limiting any other provision herein, any release or
      indemnification of Landlord shall also apply to Agent and to any property
      management company(ies) if other than Agent. 

    

    32.20

    Anti-Terrorism
      Representation.  Tenant certifies that: (i) it
      is not acting, directly or indirectly, for or on behalf of any person, group,
      entity, or nation named by any Executive Order or the United States Treasury
      Department as a terrorist, “Specially Designated National and Blocked Person,”

      to
      any law, order, rule, or regulation that is enforced or administered by the

      transaction, directly or indirectly on behalf of, or instigating or facilitating
      this transaction, directly or indirectly on behalf of, any such person, group,

      harmless Landlord and Agent from and against any and all claims, damages,
      losses, risks, liabilities, and expenses (including attorney’s fees and costs)
      arising from or related to any breach of the foregoing certification.

    

    IN
      WITNESS WHEREOF, Landlord and Tenant have

    GUARANTY

    

    

    The
      undersigned, Guarantors, hereby absolutely, irrevocably and
      unconditionally guarantee to  BDC Spotsylvania LLC, its legal
      representatives, successors, and assigns (collectively, “Landlord”), the full
      and faithful performance and observance by Tenant, its successors and assigns,
      of all terms, covenants, conditions, agreements, restrictions, and limitations
      of the Lease, including without limitation the payment of all rent and other
      obligations, howsoever denominated, and compliance with any rules and
      regulations prescribed by Landlord, together with the payment of all costs,
      attorneys’ fees, and other expenses incurred by Landlord in enforcing such
      performance and observation or enforcing the obligations under this
      Guaranty.

    

    Guarantors
      further covenant that (1) the liability of the
      Guarantors is primary, shall not be subject to deduction for any claim of
      offset, counterclaim or defense which Tenant or Guarantors may have against
      Landlord, and Landlord may proceed against Guarantors separately or jointly,
      before, after or simultaneously with any proceeding against Tenant for default;
      (2) this Guaranty shall not be terminated or impaired in any manner whatsoever
      by reason of the assertion by Landlord against Tenant of any of the rights
      or
      remedies reserved to Landlord pursuant to the provisions of such Lease, by
      reason of summary or other proceedings against Tenant, by the omission of
      Landlord to enforce any of its rights against Tenant, or by reason of any
      extension of time or indulgence granted by Landlord to Tenant or any other
      defense available to guarantors or sureties; (3) Guarantors expressly waive
      any
      requirement of notice of non-payment, non-performance or non-observance, or
      proof of notice or demand; (4) this Guaranty shall be absolute and unconditional
      and shall remain and continue in full force and effect as to any renewal,
      extension, amendment, additions, assignments, sublease, transfer or other
      modification of the Lease, whether or not currently contained in the Lease
      and
      whether or not the Guarantors have notice thereof; and (5) in any action or
      proceeding brought by Landlord against Guarantors on account of this Guaranty,
      all obligations and liabilities of Guarantors pursuant to this Guaranty shall
      be
      binding upon the heirs, personal representatives, successors and assigns of
      the
      Guarantors.  This Guaranty shall be governed by and construed in accordance
      with the laws of
                    .
  Guarantors waive trial by jury in any action brought to enforce this
      Guaranty.  If this Guaranty is governed by Commonwealth of Virginia law,
      Guarantor waives the benefit of any and all rights which Guarantor may have
      under Sections 49-25 and 49-26 of the Code of Virginia, as amended.  To the
      fullest extent permitted by law, the Guarantors waive any homestead or other
      exemptions.  The Guarantors represent that the transaction giving rise to
      this Guaranty is for a business purpose.  If any term or provision of this
      Guaranty or the application thereof to any person or circumstances shall, to
      any
      extent, be invalid or unenforceable, the remainder of this Guaranty or the
      application of such term or provision to persons or circumstances other than
      those as to which it is held invalid or unenforceable, shall not be affected
      thereby and each term and provision of this Guaranty shall be valid and
      enforceable to the fullest extent permitted by law.

    

    Upon
      request by Landlord from time to time, Guarantor shall,
      within ten (10) calendar days, provide to Landlord or to Landlord’s lender such
      financial information certified by Guarantor to be true and correct as is
      reasonably necessary for Landlord or Landlord’s lender or any prospective lender
      or purchaser, as the case may be, to evaluate the creditworthiness of Guarantor
      (including without limitation, tax returns and a statement reflecting all of
      Guarantor’s assets and the nature of Guarantor’s interest therein).

    

    In
      the event there is more than one signatory below, the
      obligations of each signatory hereunder shall be joint and several.

    

    In
      witness whereof, the undersigned has executed this Guaranty
      this      day of
                 ,

    WORK
      LETTER

    

    

    Based
      on the space plan which is attached hereto as
Exhibit D-1 (“Space Plan”), Landlord shall cause to be prepared
      final construction drawings (“Construction Drawings”).  The Construction
      Drawings shall be used for bid submission, and application for permit, and
      shall
      be forwarded to Tenant for comment.  Tenant shall have five (5) days to
      provide comments on the Construction Drawings, which Landlord shall take into
      consideration.  The Construction Drawings, as amended by any changes
      required by any governmental authority or as contemplated hereunder, and as
      approved for issuance of a building permit shall be referred to as the “Final
      Construction Drawings.”  Landlord, at its option may cause to be prepared
      interim design drawings and forward the same to Tenant for its comment which
      Landlord would take into consideration.  

    

    Upon
      receipt of the bids, Landlord shall forward the same to
      Tenant for review and comment.   Tenant shall have a three (3)-day
      period to provide comments on the bids, which Landlord take into
      consideration.

    

    Landlord
      shall build-out the Premises based Final Construction
      Drawings using building standard materials and finishes, except as otherwise
      specified on the Final Construction Drawings.  The “Tenant Improvements”
shall mean those permanent leasehold improvements constructed substantially
      in
      accordance with the Final Construction Drawings, as the same may be amended
      by
      changes, change orders, alterations or additions approved by Landlord.  For
      the purposes of construction of the Tenant Improvements, Tenant hereby
      exclusively designates Bill Elliottas Tenant’s sole representative with full
      authority to bind Tenant and to make comments on Tenant’s behalf.  Neither
      Landlord nor Landlord’s architect shall have any obligation to recognize the
      authority of, or the ability to bind Tenant by, any other persons, including
      employees and owners of Tenant, with respect to such matters or other matters
      relating to the Tenant Improvements.  Only Porter Page, Robert Sandler or
      other representatives appointed by Landlord in writing are authorized to act
      on
      behalf of the Landlord in connection with the Tenant Improvements.

    

    The
      costs of the Tenant Improvements shall mean the costs incurred
      by Landlord in designing, permitting and constructing all Tenant Improvements
      and demising the Premises, including without limitation fees of the architect,
      engineers, general contractor and construction manager.  

    

    The
      term “Tenant Delay” shall mean any delay in the construction
      of the Tenant Improvements arising from (i) Tenant's request for changes, change
      orders, alterations or additions in the Space Plan, the Construction Drawings
      or
      any other plans; (ii) any access by Tenant under Sections 2.2 or 2.3 which
      causes a delay in the construction of the Tenant Improvements; (iii) Tenant's
      request for materials, finishes or installations constituting long-lead items;
      (iv) Tenant's failure to make timely payment of the Excess Costs; (v) any event
      or time referred to herein as a Tenant Delay, or (vi) any act or omission of
      Tenant or any person, firm or corporation employed by or providing service
      to
      Tenant that delays construction of the Tenant Improvements.  To the extent
      that delay in substantially completing the Tenant Improvements is the result
      of
      any “Tenant Delay,” the Tenant shall pay to Landlord within ten (10) days of
      demand by Landlord made after the Commencement Date, an additional payment
      equal
      to the product of the Basic Monthly Rent divided by 30, multiplied by the number
      of days of the Tenant Delay (to the extent Tenant is not otherwise obligated
      for
      Basic Monthly Rent as a result of such Tenant Delay).  At Landlord’s
      option, “substantial completion” of the Tenant Improvements shall be deemed to
      mean substantial completion of all Tenant Improvements excluding long lead
      items
      and items whose completion is not practical or cost effective without the
      installation of the long lead items.  In the event Landlord has so elected
      to exclude long lead and related items from substantial completion, Tenant
      shall
      not be liable for the additional payment under this Section 2.5.1 with respect
      to the long lead items, to the extent that the long lead and related items
      did
      not delay the deemed substantial completion of the Tenant Improvements.
