in care of the Premises.

     1. DEFINITIONS. For all defined terms in this Lease, the references shall
be to Premises A or Premises B, as applicable.

     (a) "Basic Cost": The actual costs incurred by the Landlord in operating
and maintaining the Building and the Land during each calendar year of the Lease
Term for which Landlord has not been reimbursed by insurance proceeds,
condemnation awards or otherwise.

     Such costs shall include, by way of example rather than of limitation, (i)
charges or fees for, and taxes on, the furnishing of electricity, water, sewer
service, gas, fuel, or other utility services to the Building and the Land; (ii)
costs of providing elevator, janitorial, trash, snow removal service,
restriping, resurfacing, maintaining and repairing all walkways, roadways and
parking areas on the Land, security costs, and cost of maintaining grounds,
common areas, signage, and mechanical systems, sanitary sewer and drainage of
the Building and the Land; (iii) all other costs of maintaining and repairing

Landlord to the common areas of the Building and the Land in a multi-building

compensation or similar insurance upon any or all of the Building and the Land;
(viii) costs arising under service contracts with independent contractors; and
(ix) the cost of any other items which, under generally accepted accounting
principles consistently applied from year to year with respect to the Building
or the Land, constitute operating or maintenance costs attributable to any or
all of the Building or the Land; provided, however, if Landlord installs new or
replacement equipment intended to reduce operating costs, then Landlord shall
have the right to amortize such capital expense as part of Basic Costs.

     In determining Basic Cost, where less than 95% of the Building's rentable
square footage is occupied during all or any part of a year, those items of the
Basic Cost which vary according to occupancy, such as electricity and janitorial
services, shall be increased to that amount which would have been incurred had
the Building been 95% occupied during the entire year.

     (b) "Basic Rental": For Premises A: (Suite 450) shall mean an amount
payable in equal monthly installments of $2,525.00, subject to adjustment as
herein provided. For Premises B: (Suite 101) shall mean an amount payable in

     2. LEASE TERM.

     a) Landlord, in consideration of the rent to be paid and the other
covenants and agreements to be performed by Tenant and upon the terms
hereinafter stated, does hereby lease, demise and let unto Tenant the Premises,
as defined herein and generally outlined on the floor plan attached hereto as
EXHIBIT A-1 and EXHIBIT A-2, commencing on the Commencement Date and ending,
without the necessity of notice from either party to the other, on the last day
of the Lease Term, unless sooner terminated as herein provided.

     b) If the Landlord shall be unable to tender possession of the Premises on
the anticipated Commencement Date, the Landlord shall not be liable for any
damage caused thereby, nor shall this Lease be void or voidable by Tenant, but
in such event, unless the delay results (i) from failure of Tenant to provide
plans or otherwise perform in accordance with the requirements of the Lease or
(ii) from any delay in Landlord's ability to tender possession of the Premises
caused by Tenant, no rental shall be payable by Tenant prior to actual tender to
Tenant of Possession of the Premises.

     c) By occupying the Premises, Tenant shall be deemed to have accepted the
same as suitable for the purpose herein intended. Within three (3) business days
of delivery of the Premises to Tenant by Landlord, Tenant agrees to execute and
return to Landlord a letter prepared by Landlord confirming the Commencement
Date, a copy of which is attached hereto as EXHIBIT B, certifying that Tenant
has accepted delivery of the Premises and that the condition of the Premises
complies with Landlord's obligations hereunder.

     3. BASIC RENTAL.

     a) Tenant promises and agrees to pay Landlord the Basic Rental (subject to
adjustment as hereinafter provided) without demand, notice, deduction,
counterclaim, abatement or set-off, for each month of the entire Lease Term. The
first monthly installment of Basic Rental shall be due and payable upon
execution of this Lease. The Basic Rental for each subsequent month shall be
paid in advance beginning on the calendar month following the expiration of the
first calendar month of the Lease Term and continuing thereafter on or before
the first day of each succeeding calendar month during the term hereof;
provided, however, that Basic Rental for the second calendar month shall be
prorated based on one-three hundred sixtieth (1/360th) of the current annual
Basic Rental for each day of the first partial month, if any, this Lease is in
effect and shall be due and payable as aforesaid. Notwithstanding anything to
the contrary contained herein, if Tenant fails to timely pay any two (2)
installments of rent within a six-month period, Landlord at its sole option may
1) require Tenant to make all future payments on or before the due date in cash
or by cashier's check or money order, and the delivery of Tenant's personal or
corporate check shall no longer constitute payment thereof, or 2) Landlord may
require that Tenant deposit an additional Security Deposit equal to three (3)
months rent, from which Landlord, at its sole discretion, may satisfy any future
payments to be made by Tenant, and Tenant shall be required to maintain such
additional Security deposit levels throughout the remaining Lease Term as
described in Section 5 herein, in which event Tenant shall have five (5) days to
deposit such additional Security Deposit as required above.

     b) In the event that any installment of the Basic Rental, or any other sums
which become owing by Tenant to Landlord under the provisions hereof are not
received on or before the first (1st) day of the month in which such installment
is due, or any other sum hereunder within ten (10) days after accrual or billing
therefore, there shall be added to such unpaid amount a late charge of the
greater of $250.00 or ten percent (10%) of the installment or amount due in
order to compensate Landlord for the extra administrative expense thereby
incurred. After twenty (20) days have elapsed from the date of accrual or
billing, the total amount due shall bear interest at 18% per annum or the
maximum rate allowable by law.

     c) All payments due hereunder, including payment of the security deposit,
shall be made payable to "BALTIMORE BOULEVARD ASSOCIATES LIMITED PARTNERSHIP."

     4. BASIC RENTAL ESCALATION.

     The Basic Rental shall be increased annually, effective on each anniversary
of the first (1st) day of the first full month after the Commencement Date
during the term hereof. If the Commencement Date is on a day other than the
first (1st) day of the month, or on the anniversary of the Commencement date if
the Commencement date is on the first (1st) day of the month, by an amount equal
to three percent (3%) of the escalated Basic Rental then in effect, payable as

     5. SECURITY DEPOSIT.

     Landlord shall hold the Security Deposit, which shall be paid upon
execution of this Lease, without liability for interest and not in trust or in a
separate account, as security for the performance by Tenant of Tenant's
covenants and obligations under this Lease. Tenant shall not consider the
Security Deposit an advance payment of rental or a measure of Landlord's damages
in case of default by Tenant. Upon the occurrence of any Event of Default by
Tenant, Landlord may, from time to time in its sole discretion, without
prejudice to any other remedy, use and apply the Security Deposit to the extent
necessary to make good any arrearages of rent and any other damage, injury,
expense or liability suffered by Landlord by such Event of Default. Following
any such application of the Security Deposit, Tenant shall pay to Landlord on
demand as Additional Rent the amount so applied in order to restore the Security
Deposit to its original amount. If Tenant is not then in default hereunder, any
remaining balance of the Security Deposit shall be returned by Landlord to
Tenant within a reasonable period of time after the termination of this Lease
and (i) Tenant shall have surrendered the entire Premises to Landlord, (ii)
Landlord shall have inspected the Premises after such vacation, and (iii) Tenant
shall have complied with all of the terms, conditions and covenants in the Lease

charges. If Landlord transfers its interest in the Premises during the Lease
term, Landlord shall assign the Security Deposit to the transferee and
thereafter shall have no further liability for the return of such Security
Deposit. Upon the Lease Commencement Date for Premises B, the Tenant shall
tender to Landlord the amount of cash required to increase the Security Deposit
to $5,000.00 total.

     6. LANDLORD'S OBLIGATIONS.

Lease, to furnish to Tenant: (i) facilities to provide water at those points of

surrounding area. Heating, ventilation and air conditioning requirements and
standards under this Lease shall be subject, however, to such regulations as the
Department of Energy or other local, state or federal governmental agency, Board
or commission shall adopt from time to time. In addition, Landlord agrees to
maintain the public and common areas of the Building, such as lobbies, stairs,
corridors and restrooms, in reasonably good order and condition; provided,
however, that Tenant shall reimburse Landlord, upon demand for all repairs and
additional maintenance resulting from damages to such public or common area
caused by Tenant, or its employees, agents or invitees. Landlord reserves the
right, exercisable without notice and without liability to Tenant for damage or

to be provided by Landlord expressly set forth above or if any slowdown,
stoppage or interruption of, or any change in the quantity, character or
availability of, the services to be provided by Landlord expressly set forth
above occurs, such failure or occurrence shall not render Landlord liable in any
respect for damages to either person, property or business, nor be construed as

fulfillment of any covenant or agreement hereof.

service required by Tenant if such service is deemed by Landlord to be in excess
of Building standard usage, in which case the cost of installing such metering

Landlord, and in which event Tenant shall pay for all such utility service in
excess of its normal and customary usage, as metered.

Additional Rent equal to one-twelfth (1/12) of such estimate.

     (b) Within a reasonable time after the close of each calendar year during
Tenant's occupancy and the calendar year following termination of this Lease, or
as soon thereafter as practical, Landlord shall furnish to Tenant a statement of
Landlord's actual Basic Cost for the previous year. If the total of the monthly
installments paid by Tenant is less than Tenant's total annual obligation for
the Excess, Tenant shall within twenty (20) days of invoice pay the difference
upon receipt of Landlord's annual statement. Any overpayment shall be credited
to Tenant's obligation for the next succeeding period or other amounts due and
payable under this Lease.

     (c) Each statement furnished by Landlord to Tenant shall be conclusive and
binding upon Tenant unless, within thirty (30) days after receipt of such
statement, Tenant delivers to Landlord a written notice specifying the
particular details for which such statement is claimed to be incorrect. Upon
receipt of Tenant's notice, Landlord shall provide Tenant with reasonable
additional detail concerning the questioned items. Pending the determination of
such dispute, Tenant shall pay without delay the full amount of the Additional

commencement of any work in the Premises or the Building. All work performed by
Tenant within the Premises shall conform to Landlord's requirements as outlined
on EXHIBIT E, a copy of which is attached hereto. Tenant shall promptly pay all
contractors for work performed in the Premises. Where Landlord must


                                        9

<PAGE>

make repairs due to any acts or omissions by Tenant, Landlord shall have the
right, but not the obligation, to perform the work and charge Tenant for the
cost of such work, plus 15% administrative costs.

     (c) At the end or other termination of this Lease, Tenant shall deliver up
the Premises with all improvements located therein, broom clean, and in good
repair and condition, reasonable wear and tear accepted, and shall deliver to
Landlord all keys to the Premises. If Tenant shall have vacated the Premises,
Landlord may at Landlord's option re-enter the Premises at any time during the
last six (6) months of the then current term of this Lease and make any and all
such changes, alterations, revisions, additions and tenant and other
improvements in or about the Premises as Landlord shall elect, all without any
abatement of any of the rent otherwise to be paid by Tenant under this Lease.
All alterations, additions or improvements made in or upon the Premises by
Landlord or Tenant shall be Landlord's property upon termination of this Lease
and shall remain on the Premises without compensation to Tenant; provided,
however, that if Landlord so elects on or prior to the termination or upon
earlier vacation of the Premises, Tenant shall remove all alterations,
additions, improvements and partitions erected by Landlord or Tenant and shall
restore the Premises to its original condition by the date of termination of
this Lease or upon earlier vacating of the Premises, except as provided herein.
Landlord hereby elects to have any and all computer and/or telephone cables
installed by Tenant or which may in the future be installed by Tenant, removed
upon the termination of the Lease or upon Tenant's earlier vacating of the
Premises. If Tenant fails to restore the Premises upon Landlord's request,
Landlord shall have the right to perform such restoration and Tenant shall be
liable for all costs and expenses incurred by Landlord therefor.

     11. ASSIGNMENT AND SUBLETTING.

     (a) Neither Tenant nor Tenant's representatives, successors and assigns nor
any subtenant or assignee will assign, transfer, mortgage or otherwise encumber
this Lease or sublet or rent (or permit the occupancy or use of) the Premises,
or any part thereof, without obtaining the prior written consent of Landlord,
which consent will not be unreasonably withheld as provided in subsection (b)
below, nor shall any assignment or transfer of this Lease or the right of
occupancy hereunder be effectuated by operation of law or otherwise without the
prior written consent of Landlord. At the time Tenant requests Landlord's
consent, it shall provide all documents relating to the assignment or sublease,
together with a fee of One Thousand Dollars ($1,000.00) for the cost incurred by
Landlord for its initial review.

     (b) Subject to the provisions of Section 11(c) hereof, Landlord shall not
unreasonably withhold its consent hereunder to any assignment or sublease by
Tenant, provided that (x) in the event of a sublease Tenant shall satisfy each
of the following conditions prior to any such sublease becoming effective; and
(y) in the event of an assignment, Tenant shall satisfy the conditions of
subsections (i), (ii), (iii), (iv), (v) and (vi) prior to any such assignment
becoming effective:

     (i) Tenant must first notify Landlord, in writing, of any proposed
assignment or sublease, at least thirty (30) days prior to the effective date of
such proposed assignment or sublease. The


                                       10

<PAGE>

notice to Landlord must include a copy of the assignment or sublease and a copy
of the proposed assignee's or subtenant's financial statement for its most
recent fiscal year, prepared in accordance with generally accepted accounting
principles and certified by a public accountant or an executive officer of the
proposed assignee or subtenant.

     (ii) The assignee or subtenant must have a credit history satisfactory to
Landlord (in Landlord's reasonable judgment).

     (iii) Landlord shall not have been involved in litigation with the proposed
assignee or subtenant.

     (iv) The assignee or subtenant may not propose to change the use of the
premises to a purpose other than as stated in Section 9 hereof, may not conduct
its business in a manner which, in Landlord's reasonable judgment, is not
appropriate for comparable office buildings in the metropolitan Washington, D.C.
area, and may not impose a greater burden than Tenant on the Building's
facilities, parking areas, common areas, or utilities.

     (v)The assignee or subtenant may not be a tenant, subtenant, or other
occupant of any part of the Building, unless Landlord is unable to offer such
occupant comparable space elsewhere in the Building.

     (vi) The Tenant may not be in default under this Lease, or have committed
two (2) events of default hereunder during the previous twelve (12) months,
whether cured or not.

     (vii) The sublease shall contain the following clause:

               "Underlying Lease Agreement. This Sublease and Subtenant's rights
under this Sublease shall at all times be subject and subordinate to the
underlying Lease identified in Paragraph ____ hereof, and Subtenant shall
perform all obligations of Tenant under said Lease, with respect to the Sublease
Premises. Subtenant acknowledges that any termination of the underlying Lease
shall extinguish this Sublease. Landlord's consent to this Sublease shall not
make Landlord a party to this Sublease, shall not create any privity of contract
between Landlord and Subtenant or other contractual liability or duty on the
part of the Landlord to the Subtenant, shall not constitute its consent or
waiver of consent to any subsequent sublease or sub-sublease, and shall not in
any manner increase, decrease or otherwise affect the rights and obligations of
Landlord and Tenant under the underlying Lease, in respect of the Sublease
Premises. Subtenant shall have no right to assign this Sublease or further
sublet the Premises without the prior written consent of Landlord. Any term of
this Sublease that in any way conflicts with or alters the provisions of the
underlying Lease shall be of no effect as to Landlord and Landlord shall not
assume any obligations as landlord under the Sublease and Tenant shall not
acquire any rights under the Sublease directly assertable against Landlord under
the underlying Lease. Tenant hereby collaterally assigns to Landlord this
Sublease and any and all payments due to Tenant from Subtenant as additional
security for Tenant's performance of all of its covenants and obligations under
the underlying Lease, and authorizes Landlord to collect the same directly from
Subtenant and otherwise administer the provisions of this Sublease, at the
option of Landlord.


                                       11

<PAGE>

Subtenant hereby consents to such collateral assignment of this Sublease to
Landlord and agrees to observe its obligations created hereby."

     (c)Landlord shall have the right, within thirty (30) days after receipt of
the notice from Tenant, required under Section 11(b)(i) above, to elect: (i) if
Tenant proposes to assign the Lease or sublease all or substantially all of the
Premises, to terminate this Lease in its entirety, in which event the Lease
shall terminate upon the effective date of the proposed assignment or sublease,
and Tenant shall vacate the Premises as of such effective date in accordance
with the applicable provisions of this Lease; (ii) if Tenant intends to sublet a
portion of the Premises, to terminate this Lease only with respect to such
portion of the Premises, in which case Tenant shall vacate such portion as
provided in subsection (i) above; or (iii) to require Tenant to pay Landlord,
within ten (10) days of receipt, one-half (1/2) of the amount of rent payable
under such assignment or sublease in excess of the amount of rent payable by
Tenant hereunder with respect to the Premises or, in the event of a sublease,
that portion of the Premises sublet, offset by any direct expenses incurred by
Tenant actually incurred in assigning the Lease or subleasing such portion of
the Premises (amortized in equal monthly payments over the remaining term of the
Lease, if assigned, or, if applicable, over the initial term of such sublease).
Upon exercise by Landlord of either of the options set forth in subsection (i)
or (ii) above, Tenant shall surrender the Premises or such portion of the
Premises, as the case may be, to Landlord, and thereafter the rent to be paid by
Tenant pursuant to Section 3 above shall be that portion of the total rent which
the amount of square foot area remaining in the possession of Tenant bears to
the total square foot area of the Premises. In the event that Landlord does not
exercise its right to terminate this Lease, or any applicable portion thereof,
within said thirty (30) day period, Tenant shall have the right, subject to the
provisions of subsection (iii) above, to assign the Lease or sublet the Premises
or a portion thereof after first obtaining the written consent of Landlord as
provided in Section 11(a) above. Upon exercise by Landlord of the option set
forth in subsection (iii) above, Tenant covenants and agrees to provide Landlord
with semi-annual statements, prepared and verified by a certified public
accountant or executive officer of Tenant, stating the amount of rent or other
consideration received by Tenant from its assignee or subtenant(s) during such
semi-annual period. If such statement shows Tenant failed to make the full
payment to Landlord required by subsection (iii) above, a late charge equal to
ten percent (10%) of the amount due shall be paid by Tenant to Landlord as
Additional Rent, and shall be due and payable by the assignee or Tenant with the
monthly installment of rent next becoming due.

     (d)The consent by Landlord to any assignment or subletting shall not be
construed as a waiver or release of Tenant from the terms of any covenant or
obligation under this Lease, nor shall the collection or acceptance of rent from
any such assignee, subtenant or occupant constitute a waiver or release of
Tenant of any covenant or obligation contained in this Lease, nor shall any such
assignment or subletting be construed to relieve Tenant from obtaining the
consent in writing of Landlord to any further assignment or subletting. Tenant
hereby assigns to Landlord the rent due from any subtenant of Tenant and hereby
authorizes each such subtenant to pay said rent directly to Landlord, at
Landlord's option, in the event of any default by Tenant under the terms of this
Lease.


                                       12

<PAGE>

     12. INDEMNITY.

     (a)Landlord shall not be liable for, and Tenant shall indemnify and save
harmless Landlord, ground lessor, if any, and Landlord's managing agent, if any,
from and against and from all fines, damages, suits, claims, demands, losses and
actions (including reasonable attorneys' fees) for any injury to person
(including death) or damage to or loss of property on or about the Premises
caused by Tenant, its employees, contractors, subtenants, invitees or by any
other person entering the Premises or the Building under the express or implied
invitation of Tenant, or arising out of Tenant's use of the Premises. Landlord
shall not be liable or responsible for any loss or damage to any property or
death or injury to any person occasioned by theft, fire, act of God, public
enemy, criminal conduct of third parties, injunction, riot, strike,
insurrection, war, court order, requisition or other governmental body or
authority, by other tenants of the Building or any other matter beyond the
reasonable control of Landlord, or for any injury or damage or inconvenience
which may arise through repair or alteration of any part of the Building, or
failure to make repairs, or from any cause whatever except Landlord's gross
negligence or willful misconduct. Notwithstanding anything to the contrary
contained in this Lease, Landlord shall not be liable to Tenant or any other
person or entity for loss of any personal property, irrespective of how or by
whom caused.

     (b)Landlord hereby agrees to make no claim against Tenant, and will
indemnify and save Tenant, its agents, employees and invitees harmless from any
claim which shall be made against Tenant by any agent, employee, licensee or
invitee of Landlord or by others claiming the right to be on or about the common
areas for any injury, loss or damage to person or property occurring upon the
common areas, unless due to Tenant's negligence or willful misconduct.

     13. SUBORDINATION.

          This Lease and all rights of Tenant hereunder shall be and are subject
and subordinate at all times to any deeds of trust, mortgages, installment sale
agreements and other instruments or encumbrances, as well as to any ground
leases or primary leases, that now or hereafter cover all or any part of the
Building, the Land or an interest of Landlord therein, and to any and all
advances made on the security thereof, and to any and all increases, renewals,
modifications, consolidations, replacements and extensions of any of such deeds
of trust, mortgages, installment sale agreements, instruments, encumbrances or
leases, as well as any substitutions therefor, all automatically and without the
necessity of any further action on the part of Tenant to effectuate such
subordination. Tenant shall, however, within five (5) business days execute,
acknowledge and deliver to Landlord any and all instruments and certificates
that in the reasonable judgment of Landlord may be necessary or proper to
confirm or evidence such subordination. If Tenant does not respond within such
five (5) business days, Tenant hereby appoints Landlord as its Attorney-in-Fact
to execute any and all such documents on behalf of Tenant. Notwithstanding the
foregoing, if any mortgagee, trust beneficiary or ground lessor shall elect to
have this Lease treated as if it became effective and Tenant had taken
possession prior to the lien of its mortgage or deed of trust or prior to its
ground lease, and shall give notice thereof to Tenant, this Lease shall be
deemed to have become effective and Tenant's right to possession shall be
considered prior to such mortgage, deed of trust, or prior to its ground lease
whether this Lease is dated prior


                                       13

<PAGE>

or subsequent to the date of said mortgage, deed of trust or ground lease or the
date of recording thereof. In the event any mortgage or deed of trust to which
this Lease is subordinate is foreclosed or a deed in lieu of foreclosure is
given to the mortgagee or beneficiary, Tenant shall attorn to the purchaser at
the foreclosure sale or to the grantee under the deed in lieu of foreclosure; in
the event any ground lease to which this Lease is subordinate is terminated,
Tenant shall attorn to the ground lessor. Tenant shall upon demand at any time
execute, acknowledge and deliver to Landlord's mortgagee (including the
beneficiary under any deed of trust) or other holder any and all instruments and
certificates that in the judgment of Landlord's mortgagee may be necessary or
proper to confirm or evidence such attornment. Notwithstanding anything to the
contrary contained in this Section or the Lease, no mortgagee of the Building or
Land shall be liable to Tenant: (i) for the return of or responsibility for the
Security Deposit, unless and until such Security Deposit is actually received by
said mortgagee, (ii) for any act or omission of any prior landlord (including
Landlord); (iii) for any offsets, defenses or counterclaims which Tenant might
have against any prior landlord (including Landlord); (iv) for any rent,
Additional Rent or advance rent which Tenant might have paid for more than the
current month to any prior landlord (including Landlord); (v) with respect to
the provisions of any amendment or modification of the Lease made without its
consent and without written approval; or (vi) required to restore the Building,
complete any improvements or otherwise perform the obligations of Landlord under
the Lease in the event of a foreclosure of the Deed of Trust or acceptance by
such mortgagee of a deed in lieu of foreclosure, in either instances prior to
full restoration of the Building or completion of any improvements.

     14. RULES AND REGULATIONS.

          Tenant and Tenant's agents, contractors, employees and invitees will
comply fully with all requirements of the Rules and Regulations of the Building,
a copy of which is attached hereto as EXHIBIT C, and related facilities, as
specified in the Rules and Regulations now or hereafter sent by Landlord to
Tenant. Landlord shall at all times have the right to change such rules and
regulations to promulgate other Rules and Regulations in such manner as Landlord
may deem advisable, in its reasonable discretion, for safety, care or
cleanliness of the Building and related facilities or the Premises, and for
preservation of good order therein, all of which Rules and Regulations, changes
and amendments will be forwarded to Tenant in writing and shall be carried out
and observed by Tenant. Tenant shall be responsible for compliance therewith by
the agents, contractors, employees and invitees of Tenant.

     15. INSPECTION.

          Landlord or its officers, agents and representatives, and any ground
lessor or mortgagee thereof, shall have the right to enter into and upon any and
all parts of the Premises at all reasonable hours upon reasonable advance notice
(or, in any emergency or for the purpose of performing routine maintenance, at
any hour and without advance notice) to (a) inspect the Premises at any time,
(b) clean or make repairs or alterations or additions as Landlord may deem
necessary (but without any obligation to do so, except as expressly provided for
herein), or (c) show the Premises to prospective tenants, purchasers or lenders;
and Tenant shall not be


                                       14

<PAGE>

entitled to any abatement or reduction of rent by reason thereof, nor shall such
be deemed to be an actual or constructive eviction.

     16. CONDEMNATION.

          If the whole or, as determined by Landlord in its sole discretion, any
substantial part of the Land or the Building should be taken for any public or
quasi-public use under governmental law, ordinance or regulation, or by right of
eminent domain, and the taking would prevent or materially interfere with the
use of the Premises for the purpose for which they are being used, as determined
by Landlord, this Lease shall terminate and the rent shall be abated during the
unexpired portion of this Lease, effective when the physical taking of said Land
or the Building shall occur. If part of the Land or Building shall be taken for
any public or quasi-public use under any governmental law, ordinance or
regulation, or by right of eminent domain, and this Lease is not terminated as
provided in the sentence above, this Lease shall not terminate but the rent
payable hereunder during the unexpired portion of this Lease shall be reduced to
such extent as is fair and reasonable under all of the circumstances. In the
event of any such taking, Landlord and Tenant shall each be entitled to all
remedies provided by law; provided, however, that any award paid to Tenant shall
not detract from any award which Landlord is entitled to receive.

     17. FIRE OR OTHER CASUALTY.

          In the event of damage to or destruction of the Premises or the
Building, or the entrances and other common facilities necessary to provide
normal access to the Premises, caused by fire or other casualty, Tenant shall
provide immediate notice thereof to Landlord, and Landlord shall make repairs
and restorations as hereafter expressly provided, unless this Lease shall be
terminated by Landlord or unless any mortgagee which is entitled to receive
casualty insurance proceeds fails to make available to Landlord a sufficient
amount of such proceeds to cover the cost of such repairs and restoration.

          If (i) the damage is of such nature or extent, in the judgment of
Landlord's architect, that more than two hundred ten (210) consecutive days,
after commencement of the work, would be required (with normal work crews and
hours) to repair and restore the part of the Premises or Building which has been
damaged, or (ii) a substantial portion of the Premises or the Building is so
damaged that, in Landlord's sole judgment, it is uneconomic to restore or repair
the Premises or the Building, as the case may be, Landlord shall so advise
Tenant promptly; and Landlord or Tenant, for a period of ten (10) days
thereafter, shall have the right to terminate this Lease by written notice to
the other, as of the date specified in such notice, which termination date shall
be no later than thirty (30) days after the date of such notice. In the event of
such fire or other casualty, if this Lease is not terminated pursuant to the
terms of this Section 17, and if (i) sufficient casualty insurance proceeds are
available for use for such restoration or repair, and (ii) this Lease is then in
full force and effect, Landlord shall proceed promptly and diligently to restore
the Premises to its substantially similar condition prior to the occurrence of
the damage, provided that Landlord shall not be obligated to repair or restore
any alterations, additions or fixtures which Tenant or any other tenant may have
installed unless Tenant, in a manner satisfactory to Landlord, assures payment
in full of all costs which may be incurred by Landlord


                                       15

<PAGE>

in connection therewith. Tenant shall, at its sole expense, insure the value of
all leasehold improvements, fixtures, equipment or other property located in the
Premises, for the purpose of providing funds to Landlord to repair and restore
the Premises to its substantially similar condition prior to occurrence of the
damage. If Tenant does not assure or agree to assure payment of the cost or
restoration or repair of any such alteration, fixtures or additions as
aforesaid, Landlord shall have the right to determine the manner in which the
Premises shall be restored so as to be substantially the same as the Premises
existed prior to the damage occurring, as if such alterations, additions or
fixtures had not been made or installed. The validity and effect of this Lease
shall not be impaired in any way by, and Landlord shall have no liability as a
result of, the failure of Landlord to complete repairs and restoration of the
Premises or of the Building within two hundred ten (210) consecutive days after
commencement of work, even if Landlord had in good faith notified Tenant that it
estimated that the repair and restoration would be completed within such period,
provided that Landlord proceeds diligently with such repair and restoration.

          In the case of damage to the Premises not caused by the negligence or
willful misconduct of the Tenant or any of its agents, employees or invitees,
and which is of a nature or extent that Tenant's continued occupancy is
substantially impaired, the rent otherwise payable by Tenant hereunder shall be
equitably abated or adjusted for the duration of such impairment as determined
by Landlord. In no event, however, shall any damages be payable by Landlord to
Tenant in respect of business interruption resulting from any fire or other
casualty on the Premises or Building. Tenant shall be responsible to insure
and/or repair all of Tenant's personal property located in the Premises.

     18. HOLDING OVER.

          Tenant shall, at the termination of this Lease by lapse of time or
otherwise, yield up immediate possession to Landlord. If Tenant holds over after
the expiration or termination of this Lease, all of the other terms and
provisions of this Lease shall be applicable during such period, except that
Tenant shall pay Landlord from time to time upon demand, as partial damages for
the period of any holdover, an amount equal to two hundred percent (200%) of the
fair market rental value of the Premises, but in no event less than the Basic
Rental in effect on the termination date on a monthly basis, and shall not be
pro-rated for any partial month of the holdover period. No holding over by
Tenant shall operate to extend this Lease except as otherwise expressly provided
in this Lease. The foregoing notwithstanding, Landlord, in addition to accepting
the daily damages during the period of such holding over, shall be entitled to
pursue all remedies at law or equity, including, without limitation, rights to
ejectment and damages.

     19. TAXES.

     (a) For the purposes of this Section:

          (i) The term "Real Estate Taxes" means all taxes (including any rental
occupancy taxes or gross receipts tax), rates and assessments, general and
special, levied or imposed with respect to the Building and the Land or any
portion thereof including all taxes, rates and assessments,


                                       16

<PAGE>

general and special, levied or imposed for school, public betterment, general or
local improvements. If the system of real estate taxation shall be altered or
varied and any new tax or levy shall be levied or imposed on said Building and
Land or any portion thereof, and/or Landlord, in substitution of or in addition
to real estate taxes presently levied or imposed on immovable property in the
jurisdiction where the Building and Land is located, then any such new tax or
levy shall be included within the term "Real Estate Taxes".

          (ii) The term "Base Year Real Estate Taxes" means the Real Estate
Taxes applicable to calendar 2005 for Premises A and calendar 2008 for Premises
B.

     (b) The term "Real Estate Tax Year" means each successive twelve-month (12)
period, following and corresponding to the period in respect of which the Base
Year Real Estate Taxes are established, irrespective of the period or periods
which may currently, or from time to time in the future, be established by
competent authority for the purposes of levying or imposing Real Estate Taxes.

     (c) Tenant shall pay as Additional Rent throughout the term of this Lease
each month, in advance, one-twelfth (1/12th) of Tenant's estimated annual
increase in its Proportionate Share for Real Estate Taxes for or attributable to
the then current Real Estate Tax Year over the Base Real Estate Taxes (all as
defined above). Such payments shall in no way limit Tenant's annual obligation.
If the total of such monthly installments paid is less than Tenant's total
annual obligation, Tenant shall within twenty (20) days of invoice pay the
difference upon receipt of Landlord's annual Real Estate Tax statement. Any
overpayment shall be credited to Tenant's obligation for the next succeeding
period or other amounts due and payable under this Lease.

     (d) Reasonable expenses incurred by Landlord in obtaining or attempting to
obtain a reduction of any Real Estate Taxes shall be added to and included in
the amount of any such Real Estate Taxes. Real Estate Taxes which are being
contested by Landlord shall nevertheless be included for purposes of the
computation of the liability of Tenant under this Section provided, however,
that in the event that Tenant shall have paid any amount of increased rent
pursuant to this Section and Landlord shall thereafter receive a refund of any
portion of any real estate taxes on which such payment shall been based,
Landlord shall credit to Tenant the appropriate portion of such refund based on
the prior payments by Tenant. Landlord shall have no obligation to contest,
object or litigate the levying or imposition of any Real Estate Taxes and may
settle, compromise, consent to, waive or otherwise determine in its sole and
unfettered discretion any Real Estate Taxes without consent or approval of
Tenant.

     (e) Nothing contained in this Section shall be construed at any time to
reduce or give rise to a credit against the monthly installments of rent payable
hereunder below the amount stipulated in Section 3 as adjusted pursuant to
Section 4 of this Lease.

     (f) If the termination of this Lease shall not coincide with the end of the
Real Estate Tax Year, then in computing the amount payable under this Section
for the period between the commencement of the applicable Real Estate Tax year
in question and the termination date of this Lease, the Base Real Estate Taxes
shall be deducted from the Real Estate Taxes for the applicable


                                       17

<PAGE>

Real Estate Tax Year and, if there shall be a difference, such difference, pro
rated on a monthly basis, shall be payable by Tenant to Landlord within twenty
(20) days after receipt of a statement of the amount thereof.

     (g) Tenant shall be liable for all taxes levied or assessed against
personal property, furniture or fixtures placed by Tenant in the Premises, and
if any such taxes for which Tenant is liable are in any way levied or assessed
against Landlord, Tenant shall pay the Landlord upon demand that part of such
taxes for which Tenant is primarily liable hereunder.

     20. EVENTS OF DEFAULT.

          The occurrence of any of the following events shall be deemed to be an
event of default ("Event of Default") by Tenant under this Lease:

     (a)Tenant shall fail to pay when due any Basic Rental or Additional Rent or
other sums payable by Tenant hereunder.

     (b) Tenant shall fail to strictly comply with or observe Sections 13, 29
and 46 of this Lease.

     (c)Tenant shall fail to comply with or observe any other provision of this
Lease, and same is not cured within ten (10) days after Landlord's written
notice thereof; provided, however, that in the event such failure cannot be
cured within ten (10) days, and Tenant has commenced making diligent efforts to
cure such default within such ten (10) days, Tenant shall have an additional ten
(10) days to complete such cure; provided, further, that no such notice shall be
required if Tenant was previously given notice for the same or similar default
within the past three hundred sixty-five (365) days.

     (d)Tenant abandons or vacates the Premises, or removes or attempts to
remove Tenant's goods or property therefrom other than in the ordinary course of
business or does not operate or hold the Premises open for business for more
than 10 consecutive days or for more than 30 non-consecutive days during any
three-month period, without regard to whether Tenant has paid to Landlord in
full all rent and charges that may have become due.

     (e)Tenant or Guarantor (if applicable) shall apply for or consent to the
appointment of a receiver, trustee or liquidator of itself or himself or any of
its or his property, admit in writing its or his inability to pay its or his
debts as they mature, make a general assignment for the benefit of creditors, be
adjudicated a bankrupt, insolvent or file a voluntary petition in bankruptcy or
a petition or an answer seeking reorganization or an arrangement with creditors
or to take advantage of any bankruptcy, reorganization, insolvency, readjustment
of debt, dissolution or liquidation law or statute, or an answer admitting the
material allegations of a petition filed against it or him in any proceeding
under any such law, or if action shall be taken by Tenant for the purposes of
effecting any of the foregoing.

     (f)Any court of competent jurisdiction shall enter an order, judgment or
decree approving a petition seeking reorganization of Tenant or all or a
substantial part of the assets of Tenant, or


                                       18

<PAGE>

appointing a receiver, sequestrator, trustee or liquidator of Tenant or any of
its property, and such order, judgment or decree shall continue unstayed and in
effect for any period of at least thirty (30) days.

     21. REMEDIES.

          Upon the occurrence of any Event of Default specified in this Lease,
Landlord shall have the option to pursue any one or more of the following
remedies without any notice or demand whatsoever:

     (a) Distrain, collect or bring an action for such rent as may be in
arrears, and request entry of judgment therefor as provided for in case of rent
in arrears, or file a proof of claim in any bankruptcy or insolvency proceeding
for such rent, or institute any other proceedings, whether similar or dissimilar
to the foregoing, to enforce payment thereof.

     (b) Declare due and payable and sue for and recover, all unpaid rent for
the unexpired period of the Lease Term (and also all Additional Rent as the
amounts thereof can be determined or reasonably estimated) as if by the terms of
this Lease the same were payable in advance, together with all legal fees and
other expenses incurred by Landlord in connection with the enforcement of any of
Landlord's rights and remedies hereunder.

     (c) Terminate this Lease, in which event Tenant shall immediately surrender
the Premises in the condition required by this Lease to the Landlord; and if
Tenant fails to do so, Landlord may, without prejudice to any other remedy which
it may have for possession or arrearages in rent, enter upon and take possession
of the Premises and expel or remove Tenant and any other person who may be
occupying the Premises or any part thereof, without being liable for trespass or
any claim for damages therefor, and Tenant agrees to pay to Landlord as
Additional Rent on demand the amount of all loss and damage which Landlord may
suffer by reason of such termination, including the loss of rental for the
remainder of the Lease Term.

     (d) Without termination of the Lease, enter upon and take possession of the
Premises and expel or remove Tenant and any other person who may be occupying
the Premises or any part thereof, without being liable for trespass or any claim
or damages therefor; and if Landlord so elects, relet the Premises on behalf of
the Tenant on such terms as Landlord shall deem advisable and receive the rent
therefor, and Tenant agrees to pay to Landlord on demand as Additional Rent all
costs associated therewith, including brokerage fees, advertising, legal fees,
costs of tenant improvements and cost to restore premises to re-rentable
condition and any deficiency that may arise by reason of such reletting for the
remainder of the Lease Term.

     (e) Without termination of the Lease, enter upon the Premises, by force if
necessary, without being liable for trespass or any claim for damages therefor,
and do whatever Tenant is obligated to do under the terms of this Lease; and
Tenant agrees to reimburse Landlord on demand for any expenses which Landlord
may incur in thus effecting compliance with Tenant's obligations under this
Lease, and Tenant further agrees that Landlord shall not be liable for any
damages resulting to the Tenant from such action.

     (f) If Tenant fails to perform any covenant or observe any condition to be
performed or observed by Tenant hereunder or acts in violation of any covenant
or condition hereof, Landlord may, but shall not be required to on behalf of
Tenant, perform such covenant and/or take such steps, including entering upon
the Premises, as may be necessary or appropriate, and all costs and expenses
incurred by Landlord in so doing, including reasonable legal fees, shall be paid
as Additional Rent by Tenant to Landlord upon demand, plus interest at the
overdue interest rate set forth herein from the date of expenditure(s) by
Landlord, as Additional Rent. Landlord's proceeding under the rights reserved to
Landlord under this Section shall not in any way prejudice or waive any rights
Landlord might otherwise have against Tenant by reason of Tenant's default.

     (g) Exercise any other rights and remedies available to Landlord at law or
in equity. No reentry or taking possession of the Premises by Landlord shall be
construed as an election on its part to terminate this Lease, unless a written
notice of such intention is given to Tenant. Neither pursuit of any of the
foregoing remedies provided nor any other remedies provided herein or by law
shall constitute a forfeiture or waiver of any rent due to Landlord hereunder or
of any damages accruing to Landlord by reason of the violation of any of the
terms, provisions and covenants herein contained. Landlord's acceptance of rent
(including any partial payment of Basic Rental or Additional Rent) following an
Event of Default hereunder shall not be construed as Landlord's waiver of such
Event of Default. No waiver by Landlord of any violation or breach of any of the
terms, provisions and covenants herein contained shall be deemed or construed to
constitute a waiver of any other violation or Event of Default. The loss or
damage that Landlord may suffer by reason of termination of this Lease or the
deficiency from any reletting as provided for above shall include the expense of
repossession and any repairs or remodeling undertaken by Landlord following
possession. Should Landlord at any time terminate this Lease for any default,
Tenant shall not be relieved of its liabilities and obligations hereunder and,
in addition to any other remedy Landlord may have, Landlord may recover from
Tenant all damages Landlord may incur by reason of such default, including the
cost of recovering the Premises and the loss of rental for the remainder of the
Lease Term. Tenant's obligations and liabilities under this Lease shall also
survive repossession and reletting of the Premises by Landlord pursuant to the
foregoing provisions of this Section 21.

     (h) All rights and remedies of Landlord and Tenant herein enumerated shall
be cumulative, and none shall exclude any other right or remedy allowed by law.

     (i) In addition to any other rights and remedies provided in this Lease,
and with or without terminating this Lease, Landlord may with force of law,
re-enter, terminate Tenant's right of possession and take possession of the
Premises, the provision of this Section 21 operating as a notice to quit, any
other notice to quit or of Landlord's intention to re-enter the Premises being
hereby expressly waived.

     (j) In addition to the foregoing, Landlord may require Tenant to deliver,
within three (3) days of notice, an additional Security Deposit in an amount
equal to three (3) additional monthly installments of Basic Rental due as of the
date of the default.


                                       20

<PAGE>

     (k) Upon Landlord's receipt of Tenant's check which is not paid by Tenant's
bank, Tenant shall thereafter pay all amounts due under this Lease either by a
certified or cashier's check.

     22. SURRENDER OF PREMISES.

          No act done and no failure to act by Landlord or its agents during the
term hereby granted shall be deemed an acceptance of a surrender of the
Premises, and no agreement to accept a surrender of the Premises shall be valid
unless the same be made in writing and signed by Landlord.

     23. ATTORNEYS' FEES.

          In case it should be necessary or proper for Landlord to bring any
action under this Lease or to consult with an attorney concerning a default of
Tenant hereunder, irrespective of whether such default is later cured, then
Tenant shall pay any and all reasonable attorney's fees, court costs and
expenses of Landlord incurred in connection with such enforcement.

     24. LANDLORD'S LIEN.

          In addition to any statutory Landlord's lien, Landlord shall have, at
all times, and Tenant hereby grants to Landlord, a valid security interest to
secure payment of all rentals and other sums of money becoming due hereunder
from Tenant, and to secure payment of any damages or loss which Landlord may
suffer by reason of the breach by Tenant of any covenant, agreement or condition
contained herein, upon all goods, wares, equipment, fixtures, furniture,
improvements and other personal property of Tenant presently or which may
hereafter be situated on the Premises, and all proceeds therefrom; and such
property shall not be removed therefrom without the consent of Landlord until
all arrearages in rent as well as any and all other sums of money then due to
Landlord hereunder shall first have been paid and discharged and all the
covenants, agreements and conditions hereof have been fully complied with and
performed by Tenant. Upon the occurrence of any Event of Default, Landlord may,
in addition to any other remedies provided herein, enter upon the Premises and
take possession of any and all goods, wares, equipment, fixtures, furniture,
improvements and other personal property of Tenant situated on the Premises,
without liability for trespass or conversion, and sell the same at public or
private sale. Any surplus shall be paid to Tenant or as otherwise required by
law; and Tenant shall pay any deficiencies therein to Landlord forthwith. Upon
request by Landlord, Tenant agrees to execute and deliver to Landlord a
financing statement in form sufficient to perfect the security interest of
Landlord in the aforementioned property and proceeds thereof under the
provisions of the Uniform Commercial Code in force in the jurisdiction in which
the Building is located.

     25. MECHANICS' LIENS.

          Tenant shall not permit any mechanics' lien or other liens to be
placed upon the Premises or the Building or improvements thereon during the
Lease Term, caused by or resulting from any work performed, materials furnished
or obligation incurred by or at the request of Tenant. In the case of the filing
of any such lien Tenant will promptly, and in any event within five (5) days


                                       21

<PAGE>

after the filing thereof, satisfy and release of record such lien by means of
payment thereof, bonding Landlord against any loss occasioned thereby (in which
case Tenant shall have the right in due diligence to contest and dispute such
lien so long as such bond remains in place), or take such other action as may be
otherwise acceptable to Landlord. If Tenant fails to satisfy or bond off any
such claim, Landlord shall have the right to pay such amount and charge Tenant
all such costs as Additional Rent, plus fifteen (15%) percent administrative
costs.

     26. WAIVER OF SUBROGATION; INSURANCE.

     (a) Landlord and Tenant hereby release the other from any and all liability
or responsibility to the other or anyone claiming through or under them by way
of subrogation or otherwise for any loss or damage to property, but only to the
extent that such loss or damage is covered by the greater of any insurance then
in force or required to be carried hereunder, even if such fire or other
casualty shall have been caused by the fault or negligence of the other party,
or anyone for whom such party may be responsible; provided, however, that such
release shall be applicable and in force and effect only with respect to any
loss or damage occurring during such time as the policy or policies of insurance
covering said loss shall contain a clause or endorsement to the effect that this
release shall not adversely affect or impair said insurance or prejudice the
right of the insured to recover thereunder.

     (b) Tenant shall maintain throughout the Lease Term, at Tenant's sole cost
and expense, insurance against loss or liability in connection with bodily
injury, death, property damage and destruction, in or upon the Premises or the
Land, and arising out of the use of all or any portion of the same by Tenant or
its agents, employees, officers, invitees, visitors and guests, under policies
of comprehensive general public liability insurance having such limits as to
each as may be reasonably required by Landlord from time to time, but in any
event of not less than Three Million Dollars ($3,000,000) per occurrence for
death or injury and One Million Dollars ($1,000,000) per occurrence for property
damage or destruction. Such policies shall name Landlord and Tenant, (and, at
Landlord's or such mortgagee's or paramount lessor's or installment seller's
request) any mortgagee of all or any portion of the Building and any landlord
of, or installment seller to Landlord and Southern Management Corporation (and
all of its officers, members, employees, shareholders and partners) as
additional insured parties, shall provide that they shall not be modified or
canceled without at least thirty (30) days' prior written notice to Landlord and
any other party designated as aforesaid and shall be issued by insurers of
recognized responsibility licensed to do business in the jurisdiction in which
the Building is located and acceptable to Landlord. Copies of all such policies
certified by the insurers to be true and complete shall be supplied to Landlord
and such mortgagees, paramount lessors and installment sellers at all times.

     27. SUBSTITUTION SPACE.

     (a) Landlord shall have the right at any time during the term of this
Lease, including during any renewal or extension hereof, to substitute, instead
of the Premises, other space of reasonably comparable size and decor in the
Building, hereinafter referred to as "Substitution Space."


                                       22

<PAGE>

     (b) If Landlord desires to exercise such right, it shall give Tenant at
least thirty (30) days prior written notice thereof specifying the effective
date of such substitution, whereupon, as of such effective date: (i) the
description of the Premises set forth in this Lease shall, without further act
on the part of Landlord or Tenant, be deemed amended so that the Substitution
Space shall, for all intents and purposes, be deemed the Premises hereunder, and
all of the terms, covenants, conditions, provisions and agreements of this Lease
shall continue in full force and effect and shall apply to the Substitution
Space; and (ii) Tenant shall move from the Premises into the Substitution Space
and shall vacate and surrender possession to Landlord of the Premises on and
after such effective date; thereafter, during the period of such occupancy,
Tenant shall pay rent for the Substitution Space at the above-described rate,
whereupon rent shall abate entirely with respect to the Premises.

     (c) If Landlord exercises its relocation right, Landlord shall reimburse
Tenant for Tenant's reasonable out-of-pocket expenses for moving Tenant's
furniture, equipment, supplies and telephones and telephone equipment from the
presently leased Premises to the Substitution Space and for reprinting Tenant's
stationery of the same quality and quantity of Tenant's stationary supply on
hand immediately prior to Landlord's notice to Tenant of the exercise of this
relocation right.

     28. BROKERAGE.

          Landlord and Tenant warrant that each has had no dealings with any
broker or agent other than CB Richard Ellis (for both Landlord and Tenant) in
connection with the negotiation or execution of this Lease, and each agrees to
indemnify the other against all costs, expenses, attorneys' fees or other
liability for commissions or other compensation or charges claimed by any other
broker or agent claiming the same by, through such party.

     29. ESTOPPEL CERTIFICATES.

          Tenant shall from time to time, within ten (10) days after Landlord
shall have requested the same of Tenant, execute, acknowledge and deliver to
Landlord a written instrument in such form as required by Landlord (i)
certifying that this Lease is in full force and effect and has not been
modified, supplemented or amended in any way (or, if there have been
modifications, supplements or amendments thereto, that it is in full force and
effect as modified, supplemented or amended and stating such modifications,
supplements and amendments); and (ii) stating any other fact or certifying any
other condition reasonably requested by Landlord or requested by any mortgagee
or prospective mortgagee or purchaser of the Property or of any Interest
therein. In the event that Tenant shall fail to return a fully executed copy of
such certificate to Landlord within the foregoing ten (10) day period, then
Tenant shall be deemed to have approved and confirmed all of the terms,
certifications and representations contained in such certificate, and Tenant
irrevocably authorizes and appoints Landlord as its attorney-in-fact to execute
such certificate on behalf of Tenant.

          The provisions of this Lease may not be waived, altered, changed or
amended, except by an instrument in writing signed by both parties hereto, and

lessors of record. The acceptance of Basic Rental, Additional Rent or other

upon Tenant shall be joint and several. If there is a guarantor of Tenant's
obligations hereunder, the obligations hereunder imposed upon Tenant shall be
the joint and several obligations of Tenant and such guarantor, and Landlord
need not first proceed against Tenant before proceeding against such guarantor
nor shall any such guarantor be released from its guaranty for any reason
whatsoever, including without limitation any extensions or renewals hereof, any
amendments hereto, any waivers hereof or failure to give such guarantor any

space and corridors in the Building, to interrupt or temporarily suspend
Building services and facilities and to change the arrangement and location of
entrances or passageways, doors and doorways, corridors, elevators, stairs,

<PAGE>

     (c) To maintain, relocate, erect pipes and conduits through Tenant's space.

not operate to exclude Tenant from the use expressly permitted herein.

     (e) To alter, increase, reduce, reconfigure and relocate the common areas.

     (f) To take all such reasonable measures as Landlord may deem advisable for
the security of the Building and its occupants, including without limitation,

subject, however, to Tenant's right to admittance when the Building is closed
after normal business hours under such reasonable regulations as Landlord may
prescribe from time to time which may include, by way of example but not of
limitation, that person entering or leaving the Building, whether or not during
normal business hours, identify themselves to a security officer by registration
or otherwise and that such persons establish their right to enter or leave the
Building.

     38. FINANCIAL STATEMENTS.

          Tenant agrees to provide to Landlord within ten (10) days of request
by Landlord but no more than once per year, the most recent audited annual
financial statements of Tenant, including balance sheets, income statements, and
financial notes ("Statements"). Tenant consents that Landlord may release the
Statements to Landlord's subsidiaries, affiliates, lenders, advisors, joint
venture partners, or potential purchasers of the property for the purposes of
evaluating Tenant's financial condition with respect to performance under the
Lease. Landlord agrees to keep the Statements confidential and to not release
the Statements to third parties except as set forth herein.

     39. NOTICE TO LENDER.

          If the Premises or the Building or any part thereof are at any time
subject to a mortgage or a deed of trust or other similar instrument and the
Lease or the rentals are assigned to such mortgagee, trustee or beneficiary and
the Tenant is given written notice thereof, including the post office address of
such assignee, then Tenant shall not exercise any remedies under the Lease
without first giving written notice by certified mail, return receipt requested,
to such mortgagee, trustee, beneficiary and assignee, specifying the default in
reasonable detail, and affording such mortgagee, trustee, beneficiary and
assignee a reasonable opportunity to make performance, at its election, for and
on behalf of the Landlord. Tenant shall be deemed to have received written
notice of any mortgage or deed of trust encumbering the Building and/or the Land
as of the date of this Lease.

     40. MISCELLANEOUS.

     (a) Any approval by Landlord and Landlord's architects and/or engineers of
any of Tenant's drawings, plans and specifications which are prepared in
connection with any construction of improvements in the Premises shall not in
any way be construed or operate to bind Landlord or to constitute a
representation or warranty of Landlord as to the adequacy or sufficiency of such
drawings, plans and specifications, or the improvements to which they relate, or
any use, purpose, or condition, but such approval shall merely be the consent of
Landlord as may be required hereunder in connection with Tenant's construction
of improvements in the Premises in accordance with such drawings, plans and
specifications.

     (b) Each and every covenant and agreement contained in this Lease is, and
shall be construed to be, a separate and independent covenant and agreement.

representations or promises with respect to the Premises, the Building or the
Land except as herein expressly set forth and no rights, easements or licenses
are acquired by Tenant by implication or otherwise except as expressly set forth
in the provisions of this Lease.

     (d) Time is of the essence as to all provisions of this Lease applicable to
Tenant's obligations hereunder.

offer, nor shall Tenant have any rights with respect thereto unless and until
Landlord shall, or shall cause its managing agent to, execute a copy of this
Lease and deliver the same to Tenant.

     (f) Notwithstanding anything to the contrary contained in this Lease, if
the Lease Term has not commenced within twenty-one (21) years after the date of
this Lease, this Lease shall automatically terminate on the twenty-first (21st)
anniversary of such date. The sole purpose of this provision is to avoid any
interpretation of this Lease as a violation of the Rule Against Perpetuities, or
any other rule of law or equity concerning restraints on alienation.

     (g) The terms of this Lease shall be construed in accordance with the laws
of the jurisdiction in which the Building is located.

     (h) Neither this Lease, nor any memorandum, affidavit or other writing with
respect thereto, shall be recorded by Tenant or by any one acting through, under
or on behalf of Tenant, and the recording thereof in violation of this provision
shall make this Lease null and void at Landlord's election.

     41. ADDITIONAL RENT.

          The Tenant shall pay as Additional Rent any money required to be paid
pursuant to the provisions of this Lease whether or not the same is designated
"Additional Rent". If such amounts or charges are not paid at the time provided
in this Lease, they shall nevertheless, if not paid when due, be collectable as
Additional Rent with the next installment of rent thereafter


                                       28

<PAGE>

falling due hereunder, but nothing herein contained shall be deemed to suspend
or delay the payment of any amount of money or charge at the time the same
becomes due and payable hereunder, or limit any other remedy of the Landlord.
Notwithstanding any expiration or termination of this Lease prior to the end of
the Lease Term, Tenant's obligations to pay any and all Additional Rent pursuant
to this Lease shall continue and shall cover all periods up to the expiration or
termination date of this Lease. Tenant's obligation to pay any and all
Additional Rent or other sums owing by Tenant to Landlord under this Lease shall
survive any expiration or termination of this Lease.

     42. ENTIRE AGREEMENT.

          The Lease contains all covenants and agreements between Landlord and
Tenant relating in any manner to the rent, use and occupancy of Premises and
Tenant's use of the Building and other matters set forth in this Lease. No prior
agreement or understanding pertaining to the same shall be valid or of any force
or effect and the covenants and agreements of this Lease shall not be altered,
modified or added to except in writing signed by Landlord and Tenant.

     43. LEGAL PROCEEDINGS.

          Landlord and Tenant hereby waive the right to a jury trial in any
action, proceeding or counterclaim between Tenant and Landlord or their
successors arising out of this Lease or Tenant's occupancy of the Premises or
Tenant's right to occupy the same.

     44. LAWS AND REGULATIONS.

          Tenant agrees at Tenant's expense to comply with all applicable laws,
ordinances, rules, and regulations, whether now in effect or hereafter enacted

occupancy for the Premises.

defined in the ADA.

     (b) The Tenant at its sole cost and expense shall be solely responsible for
taking any and all measures which are required to comply with the requirements
of Title I and/or Title III of the ADA within the Premises and, if the measures
required outside of the Premises are attributable to Tenant's alterations to the
Premises, outside of the Premises as well. Any Alterations to the Premises made
by Tenant for the purpose of complying with the ADA or which otherwise require
compliance with the ADA shall be done in accordance with this Lease; provided,
however, that Landlord's consent to such Alterations shall not constitute either
Landlord's assumption, in whole or in part, of Tenant's representation or
confirmation by Landlord that such Alterations comply with the provisions of the
ADA.


                                       29

<PAGE>

     (c) Tenant shall indemnify the Landlord for all claims, damages, judgments,
penalties, fines, administrative proceedings, costs, expenses and liability
arising from Tenant's failure to comply with any of the requirements of Title I

     (e) Notwithstanding the provisions of subsection (b) herein, if (i)
Landlord causes Alterations or improvements to be made to the common areas of

against any and all liability, loss, damage, cost or expense (including
reasonable attorneys' fees) that Landlord may


                                       30

<PAGE>

suffer or incur as a result of any claims, demands, damages, losses,
liabilities, costs, charges, suits, orders, judgments or adjudications asserted,
assessed, filed, or entered against Landlord or any of the Building or the Land,
by any third party, including, without limitation, any governmental authority,
arising from Tenant's breach of Environmental Laws or otherwise arising from the

     (c) Tenant, its permitted subtenants, licensees, invitees, agents,
contractors, subcontractors and employees shall not release, spill, pump, pour,
emit, empty, dump or otherwise discharge or allow to escape Hazardous Materials
onto the Land or Building, and Tenant shall take all action necessary to remedy
the results of any such release, spillage, pumping, pouring, emission, emptying,
dumping, discharge, or escape.

     (d) Tenant shall within 48 hours of receipt deliver to Landlord copies of
any written communication relating to the Building or the Land between Tenant
and any governmental agency or instrumentality concerning or relating to
Environmental Laws.

     (e) Tenant's obligations under this Section shall survive the termination
or other expiration of this Lease.

     47. PARKING.

          Tenant, its permitted subtenants, licensees, invitees, agents,
contractors, subcontractors and employees shall not use parking spaces on the
Land or Building in excess of that number set out on the attached Data Sheet
which has been reasonably determined by Landlord to be Tenant's proportionate
share of the total parking spaces available on the Building and Land. All such
spaces are available on a first-come, first-served, non-exclusive basis, to all
tenants in the Building, and shall be unmarked and unreserved. At such time and
under such circumstances as Landlord deems appropriate, Landlord may provide
attendant parking or such other system or management of parking as it deems
necessary or desirable. Notwithstanding anything contained herein, if any
governmental regulation or ordinance is enacted or amended after the effective
date of this Lease so as to allow or require a modification in Tenant's number
of parking spaces, Landlord reserves the right to make such modification without
modifying in any way the rent due hereunder or any other obligations of Tenant.
Tenant shall not use parking for overnight storage of vehicles. Landlord assumes
no responsibility and shall not be liable for any vehicle damage or theft to
vehicles located in the parking lot, nor theft of personal property or personal
injury sustained by any person in or about the parking lot.

          The Tenant shall have the right to utilize two (2) reserved parking
spaces within the Building garage at the current rate of $50.00 per space per
month. This amount shall be paid to the Landlord along with the Basic Rental in
advance on the first day of each and every calendar month of the Lease Term. The
Landlord reserves the right to adjust the monthly cost of garage


                                       31

<PAGE>

parking spaces from time to time.

     48. AUTHORITY.

          Tenant is a duly organized and validly existing corporation which is
qualified to do business in the state where the Building is located. Tenant has
full right, power and authority to enter into this Lease, and that each person
signing on behalf of Tenant is authorized to do so. Upon Landlord's request,
Tenant shall provide Landlord with a copy of a corporate resolution of the Board
of Directors of the Tenant confirming the foregoing.

     49. Renewal Option.

          Tenant shall have the right to extend the term of the Lease for
Premises B (Suite 101) for two (2) additional five year lease terms (the
"Renewal Term"), upon the following conditions:

     (a) Tenant has not been in default (past applicable notice and cure) at any
time during the past twelve (12) month period;

     (b) Tenant has not previously assigned the Lease or sublet any part or all
of the Premises;

     (c) Landlord, using its reasonable judgment is satisfied with the quality,
appearance, service and cleanliness of the Tenant's business.

     (d) Tenant has delivered to Landlord written notice of its intention to
exercise this option, not less than three hundred sixty five (365) days prior to
the end of the Lease Term;

     (e) All lease terms for the Renewal Term shall be the same as in the
initial Lease Term, except that the annual Base Rent for the Renewal Term shall
be the greater of: z) then current market rent for comparable space in the
Building or in comparable buildings in the market (but not less than the most
recent Monthly Base Rent), or y) the Basic Rental of the final month of the
Lease Term increased by three (3%) percent; and

     (f) there shall be no further option to renew the Lease Term; and

     (g) there shall be no Improvement Allowance.

     If Tenant fails to sign an Amendment to the Lease extending the Lease Term
as provided in this Section within fifteen (15) days after the rent has been
determined and Landlord has promptly provided Tenant with a proposed Amendment
consistent with the foregoing, all time periods for Tenant herein being of the
essence, then Tenant's option to extend the term of this Lease shall lapse and
Tenant's renewal option shall be of no force and effect. The Renewal Option is
personal to Tenant and is non-transferable.

     50. EXTERIOR SIGNAGE. Tenant, at its sole cost and expense, shall have the
right to affix two exterior signs to the facade of the Building in the
approximate locations depicted on EXHIBIT G-1 AND G-2. These signs may be
installed only after Tenant has occupied the branch space in Suite 101 which is
expected to be on or about January 1, 2008. Tenant shall submit for review the
scale drawings and signage specifications which shall be subject to Landlord's
approval not be unreasonably withheld, conditioned, or delayed. Tenant shall
also be responsible for prompt repairs and ongoing maintenance of the sign. At
the expiration or earlier termination of this Lease, Tenant shall be responsible
for patching the holes and restoring the Building facade to its original
condition, reasonable wear and tear excepted.

                              RULES AND REGULATIONS

     The following rules and regulations have been formulated for the safety and
well being of all the tenants of the Building. Any violation of these rules and
regulations by any tenant that continues after notice from Landlord shall be
sufficient cause for termination, at the option of Landlord, of the tenant's
lease.

     1. The sidewalks, entrances, passages, courts, elevators, vestibules,
stairways, corridors or hall or other parts of the Building not occupied by any
tenant shall not be obstructed or encumbered by any tenant or used for any
purpose other than ingress and egress to and from the tenant's Premises.
Landlord shall have the right to control and operate the common areas, and the
facilities furnished for the common use of the tenant in such manner as
Landlord, in its sole discretion, deems best for the benefit of the tenants
generally. No tenant shall permit the visit to its Premises of persons in such
number or under such conditions as to interfere with the use and enjoyment by
other tenants of the common areas.

     2. No awnings or other projections shall be attached to the outside walls
of the Building. No drapes, blinds, shades or screens shall be attached to or
hung in, or used in connection with, any window or door of a tenant's Premises.

     3. No sign, advertisement, notice or other lettering or material(s) shall
be exhibited, inscribed, painted or affixed by any tenant on any part of the
outside or inside of the tenant's Premises, the Building or elevators. In the
event of the violation of the foregoing by any tenant, Landlord may remove it
without any liability, and may charge the expense incurred by such removal to
the tenant or tenants violating this rule. All interior signs on the doors and
directory table shall be inscribed, painted or affixed for each tenant by
Landlord at the expense of such tenant, and shall be of a size, color and style
acceptable to Landlord.

     4. No show cases or other articles shall be put in front of or affixed to
any part of the exterior of the Building, or placed in the common areas.

     5. The water and wash closets and other plumbing fixtures shall not be used
for any purpose other than those for which they were constructed, and no
sweepings, rubbish, rags or other substances shall be thrown or placed therein.
All damages resulting from any misuse of the fixtures shall be borne by the
tenant whose employees, agents, visitors or licensees shall have caused the
same.

     6. There shall be no marking, painting, drilling into or other form of
defacing or damage of any part of a tenant's Premises or the Building. No
boring, cutting or stringing of wires shall be permitted. No tenant shall
construct, maintain, use or operate within its Premises or elsewhere within or
on the outside of the Building, any electrical device, wiring or apparatus in
connection with a loud speaker or other sound system. Landlord will, however
permit a tenant to install Muzak or other


                                       38

<PAGE>

internal music system within the tenant's Premises if the music system cannot be
heard outside of the Premises.

     7. No tenant shall make or permit to be made any disturbing noises or
disturb or interfere with the occupants of the Building or neighboring buildings
or premises or those having business with them, whether by the use of any
musical instrument, radio, tape recorder, whistling, singing or any other way.

down the corridors or stairs.

     8. No bicycles, vehicles or animals, birds or pets of any kind shall be
brought into or kept in or about a tenant's Premises. No cooking shall be done
or permitted by any tenant on its Premises, except that, with Landlord's prior
written approval, a tenant may install and operate for the convenience of its
employees, a lounge or coffee room with a microwave oven, sink and refrigerator.
No tenant shall cause or permit any unusual or objectionable odors to originate
from its Premises. Each tenant shall be obligated to maintain sanitary
conditions in any area approved by the Landlord for food and beverage
preparation and consumption.

     9. No space in or about the Building shall be used by any tenant for the
manufacture, storage, or sale or auction of merchandise, goods or property of
any kind.

     10. No flammable, combustible, explosive, hazardous or toxic fluid,
chemical or substance shall be brought into or kept upon a tenant's Premises.

     11. No additional locks or bolts of any kind shall be placed upon any of
the doors or windows by any tenant, nor shall any changes be made in existing
locks or the mechanism thereof. The doors leading to the common areas shall be
kept closed during business hours except as they may be used for ingress and
egress. Each tenant shall, upon the expiration or termination of its tenancy,
return to Landlord all keys used in connection with its Premises, including any
keys to the Premises, to rooms and offices within the Premises, to storage rooms
and closets, to cabinets and other built-in furniture, and to toilet rooms
whether or not such keys were furnished by Landlord or procured by tenant, and
in the event of the loss of any such keys, such tenant shall pay to Landlord the
cost of replacing the locks. On the expiration or termination of a tenant's
lease, the tenant shall disclose to Landlord the combination of all locks for
safes, safe cabinets and vault doors, if any, remaining in the Premises.

     12. All deliveries and removals, or the carrying in or out of any safes,
freight, furniture of bulky matter or materials of any description, must take
place in such manner and during such hours as Landlord may require. Landlord

materials to be brought into the Building and to exclude from the Building all
or any of such which violates any of these rules and regulations or the Lease.

     13. Any person employed by any tenant to do janitorial work within the
tenant's Premises must obtain Landlord's written consent prior to commencing
such work, and such person shall, while in the Building and outside of the

the tenant's Premises, except those actually working for such tenant on said
Premises.

     14. No tenant shall purchase spring water, ice, coffee, soft drinks,
towels, or other like merchandise or service from any company or person whose
repeated violations of Building regulations have caused, in Landlord's sole
opinion, a hazard or nuisance to the Building and/or its occupants.

     15. Landlord shall have the right to prohibit any advertising by any tenant
which, in Landlord's sole opinion, tends to impair the reputation of the
Building or its desirability as a Building for offices, and upon written notice
from Landlord, such tenant shall refrain from or discontinue such advertising.

     16. Landlord reserves the right to exclude from the Building at all times
any person who is not known or does not properly identify himself to the
Building management or its agents. Landlord may at its option require all
persons admitted to or leaving the Building between the hours of 6:00 p.m. and
8:00 a.m., Monday through Friday, and at all times on Saturdays, Sundays and
holidays, to register. Each tenant shall be responsible for all persons for whom
it authorizes entry into the Building, and shall be liable to Landlord for all
acts of such persons.

     17. Each tenant, before closing and leaving its Premises at any time, shall
assure that all lights are turned off and the Premises are locked.

     18. The requirements of tenants will be attended to only upon application
at the office of the Building. Building employees shall not perform, and shall
not be requested by any tenant to perform any work or do anything outside of

for lodging or sleeping or for any immoral or illegal purpose.

     25. Employees of Landlord other than those expressly authorized are

                  Rules and Regulations for Tenant Alterations

A.   Prior to Commencing Construction

     1. Plans. Submit plans and specifications (or other descriptions reasonably
acceptable to Landlord) of the proposed Alterations to Landlord for its review
and written approval. If Landlord raises any issues as a result of its review of
the submitted plans and specifications, these issues must be resolved to
Landlord's reasonable satisfaction. Alterations to structural components of the
Building shall be reviewed and approved in Landlord's sole and absolute
discretion and non-structural changes shall be approved at Landlord's
discretion, which shall not be unreasonably withheld, conditioned or delayed.
Once approved, no changes, amendments or additions to the plans and
specifications may be made without Landlord's prior written consent, which shall
not be unreasonably withheld, conditioned or delayed.

     2. Contractors. The general contractor, contractors and subcontractors
selected by Tenant must be approved by Landlord; such approval shall not be
unreasonably withheld, conditioned or delayed. Provisions must be made for all
contractors, laborers and materialmen to provide written lien waivers related to
the approved Alterations.

     3. Insurance. The general contractor, contractors and subcontractors
selected by Tenant must provide certificates of insurance evidencing the
coverage shown below prior to beginning any work on the approved Alterations.
This coverage must be maintained in full force and effect until such time as the
approved Alterations are fully completed. Any delay by Tenant in causing these
certificates to be provided will result in a delay in the commencement of the
approved Alterations.

     4. Permits. Tenant must obtain all required permits ("Permits") and furnish
copies thereof to Landlord.

     5. Coordination. Tenant shall contact Landlord's Property Manager to
arrange a pre-construction meeting and walk-through with the Tenant's
contractor. During this walk-through these Rules and Regulations, hours of
operation and access will be reviewed and areas of the Building (e.g. lobby
floors and walls, elevators, electrical closets and doors) will be inspected.
These areas will be inspected after completion of the approved Alterations to
determine whether or not any damage has occurred thereto. Any damage will be
repaired to Landlord's reasonable satisfaction.

B.   During Construction.

     1. Compliance. All work on the approved Alterations shall, at all times,
comply with laws, rules, orders and regulations of all applicable governmental
authorities and insurance bodies and the Permits.


                                       43

<PAGE>

     2. Schedule. If requested, construction work schedules must be filed with
the Property Manager. Contractors must check in each day with the designated
Building engineer. The Property Manager must be notified, in writing, of the
names of any persons working on the approved Alterations who may be working in
the Building after the normal business hours.

     3. Coordination. Twenty-four (24) hour advance written notice must be
provided to the Property Manager:

          (a) before commencing any and all work which may cause disruption to
other tenants or interruption to the Building's systems and the Property Manager
may require that work deemed inappropriate to be conducted during normal
business hours be done after hours; or,

          (b) if access to utility rooms or the roof will be necessary (anyone
on the roof must be escorted by property management at all times); or,

          (c) if the fire panel is to be taken out of service; or,

          (d) if there is to be any interruption to any Building system or
utility; or,

     4. Material Delivery and Storage. All deliveries are to come through the
loading and service areas of the Building. All construction materials, tools and
trash are to be transferred to and from the construction floor via the freight
elevator or stairs. At no time may the passenger elevators be used to move
materials, tools or trash. Tenant and its contractor shall be responsible for
(i) protecting the freight elevator to the satisfaction of the Property Manager,
and (ii) observing the load limits for the freight elevator and (iii) any
damages due to improper use or overloading of the freight elevator. Use of the
freight elevator shall be scheduled in advance with the security guard and the
contractor may be required to share the freight elevator with the cleaning crew.
Materials must be immediately placed in the Tenant's Leased Premises and may not
be stored in any of the Building's Common Areas.

     5. Damage. Tenant and its contractors shall be responsible for any damage
to the Building or the Building systems caused by or arising out of the making
of the approved Alterations and shall promptly repair it to the reasonable
satisfaction of Landlord. Precautions to minimize damage to the Common Areas of
the Building should be taken including protection of doors, carpets, elevator
cabs and hallways. Masonite must be placed on the floors of any public corridor
to protect the floor covering. In Common Areas with carpeting, the floor
protection is to be removed and the carpet vacuumed daily. If the approved
Alteration will involve drywall sanding or other dust


                                       44

<PAGE>

producing activities, all air and smoke detectors must be covered during drywall
sanding or other dust producing activities. The contractor must provide
sufficient fire extinguishers at all times.

     6. Trash. Regular Building dumpsters are not to be used for construction
debris without the prior approval of property management. Tenant and its
contractor(s) are responsible for ensuring that all trash is placed properly
within a separate construction dumpster and for clearing, on a daily basis, the

property management prior to beginning the approved Alterations. The dumpster

contractors. No vehicles of any contractor or subcontractor are to block service
areas or any dumpster at any time. There is to be no smoking in the Building and

glass without the prior written consent of the Property Manager.

C.   After Completion

     1. Coordination. A re-inspection of the lobby floor and walls, doors,

damage has occurred or any clean-up is required.
