(b) References and Conflicts. References appearing in Section
1(a) are intended to designate some of the other places in the Lease
where additional provisions applicable to the particular Fundamental
Lease Provisions appear. These references are for convenience only and
shall not be deemed all inclusive. Each reference in this Lease to any
of the Fundamental Lease Provisions contained in Section l(a) shall be
construed to incorporate all of the terms provided for under such
provisions, and such provisions shall be read in conjunction with all
other provisions of this Lease applicable thereto. If there is any
conflict between any of the Fundamental Lease Provisions set forth in
Section l(a) and any other provisions of the Lease, the latter shall
control.

(c) Exhibits. The following drawings and special provisions are attached
hereto as exhibits and hereby made a part of this Lease:

2. PREMISES.

(a) Demised Premises. Landlord hereby leases to Tenant, and Tenant hereby
rents from Landlord, the Demised Premises as specified in Section l(a)(l)
located in the Building specified in Section l(a)(2) at the address specified in
Section l(a)(3). The Demised Premises shall consist of approximately the square
footage of rentable floor space as specified in Section l(a)(4) and as shown on
floor plan attached hereto as Exhibit "A". Upon completion of Tenant's Space
Plan, as specified in Exhibit B and Subsection 6(a), Landlord's architect shall
determine the exact number of rentable square feet in the Demised Premises in
accordance with the ANSI/BOMA Method (hereinafter defined), and the Base Annual
Rent and Tenant's Proportionate Share shall be proportionately adjusted.
Landlord shall cause its architect to timely provide to Tenant a copy of the
ANSI/BOMA calculations used to determine the rentable square footage. The
parties agree that the rentable square footage of the Demised Premises,
determined pursuant to this section, and the adjusted Base Annual Rent and
Tenant's Proportionate Share shall be set forth in the Certificate of
Commencement, attached hereto as Exhibit "E", to be executed by the parties
within fifteen (15) days after the Commencement Date of the Lease Term. As used
herein, the "ANSI/BOMA" method shall mean the standard method for measuring
floor area in office buildings ANSI/BOMA Z65.1-1996

(b) Building. Tenant acknowledges Landlord's statement that the gross
rentable area in the Building is specified in Section l(a)(5). Landlord reserves
the right to modify the rentable area of the Building from time to time during
the Lease Term as a result of construction of new improvements, the demolition
of existing improvements, or inclusion of improvements not currently within the
boundaries of the Building.

(c) Tenant's Proportionate Share. Tenant's Proportionate Share of certain
expenses hereinafter made payable to Landlord as Additional Rent is specified in
Section l(a)(6) and Section 4(c)(ii). Said computation is based upon the ratio
of the total rentable area of the Demised Premises to the rentable area of the
Building. The Proportionate Share shall be modified during the Lease Term in the
event that the rentable area of the Building is modified as described in Section
2(b) above or in the event that the architect's calculation described in Section
2(a) above shows a different square footage for the Demised Premises.

3. TERM.

(a) Lease Term. The term of this Lease (sometimes herein called the "Lease
Term") shall commence on the "Commencement Date" and, subject to sooner
termination as herein provided, ending the number of years specified in Section
1(a)(7) after the Rent Commencement Date (the "Expiration Date"). The period
commencing with the Rent Commencement Date (on the first day of the next
calendar month in the event the Rent Commencement Date does not occur on the
first day of a month) and ending on the last day of the twelfth calendar month
thereafter shall constitute the first "lease year" as such term is used herein.
Each successive full twelve (12) month period during the Lease Term shall
constitute a "lease year".

(b) Inability to Deliver Possession. If Landlord shall be unable to tender
possession of the Demised Premises on the Commencement Date set forth in Section
1(a)(8), if Tenant is constructing the tenant improvements, or by the Rent
Commencement Date set forth in Section l(a)(9), if Landlord is constructing the
tenant improvements, by reason of: (a) the fact that the Demised Premises are
located in a Building being constructed and which has not been sufficiently
completed to make the Demised Premises ready for occupancy; (b) the holding over
or retention of possession of any tenant or occupant; (c) the failure to
complete repairs, improvements or decoration of the

Demised Premises or of the Building; or (d) for any other reason, Landlord shall
not be subject to any liability for the failure to tender possession on said
date. In the case of holding over, provided Landlord shall promptly institute
suit for recovery of the Demised Premises and diligently pursue the same,
Landlord shall have no responsibility for any delay in tendering possession of
the Demised Premises. Under any of the aforesaid circumstances, the rent
covenanted to be paid herein shall not commence and the Commencement Date (if
Tenant is constructing the tenant improvements, or the Rent Commencement Date,
if Landlord is constructing the tenant improvements) shall not occur until
possession of the Demised Premises is tendered to Tenant as contemplated in
Section l(a)(8); provided, however, that the Rent Commencement Date shall not be
postponed by (i) any delays occasioned by Tenant's failure to perform any of its
obligations with respect to the construction of the Demised Premises within the
time frames for such performance set forth in Exhibit "C", or (ii) any delays in
construction caused by any contractors retained by Tenant, or (iii) any delays
in construction resulting from delays in the delivery or installation of
improvements specified in Tenant's Space Plan which are not Building Standard,
provided that Landlord shall have informed Tenant that such improvements would
result in construction delays prior to final Space Plan approval. No such
failure to give possession on the date set forth in Section l(a)(8) or the Rent
Commencement Date set forth in Section 1(a)(9) (as applicable), shall in any
other respect affect the validity of this Lease or the obligations of Tenant
hereunder, nor shall same be construed to modify the Lease Term, which in all
events shall be the number of years set forth in Section l(a)(7); provided,
however, that if Landlord shall not have tendered possession of the Demised
Premises to Tenant nine (9) months after the date set forth in Section l(a)(8),
or the Rent Commencement Date set forth in Section l(a)(9) (as applicable), then
either Landlord or Tenant may terminate this Lease by written notice to the
other party. In such event, Landlord shall refund any security deposit and
advance rental payment theretofore paid by Tenant, and the parties shall
thereupon be relieved of any and all liability hereunder. If permission is given
to Tenant to enter into the possession of the Demised Premises prior to the
Commencement Date in Section 1(a)(8), or the Rent Commencement Date set forth
in Section l(a)(9) (as applicable), Tenant covenants and agrees that such
occupancy shall be deemed to be under all the terms, covenants, conditions and
provisions of this Lease and the Commencement Date or the Rent Commencement Date
(as applicable) will coincide with the date of occupancy. Within fifteen (15)
days after the Rent Commencement Date, Landlord and Tenant shall execute a
Certificate of Commencement in the form of Exhibit "E".

4. RENT.

(a) Base Annual Rent. The Base Annual Rent reserved hereunder shall be as
specified in Section l(a)(12) which shall be payable by Tenant to the Landlord
during each lease year of the Lease Term in equal monthly installments of Base
Monthly Rent each as specified in Section 1(a)(l3). Tenant shall pay the first
monthly installment of Base Annual Rent upon execution of this Lease, which
payment shall be credited against the first payment of Base Monthly Rent
required by this Lease. Tenant shall pay the remaining monthly installments of
Base Annual Rent in advance, without notice or demand, and without set-off,
deduction or abatement of any kind, on or before the first day of each and every
calendar month throughout the entire term of the Lease, at the office of the
Rental Agent specified in Section l(a)(l1), or to such other person or at such
other address as Landlord may designate by written notice to Tenant from time to
time.

(b) Adjustments to Base Annual Rent. On the first day of the second lease
year, and on the first day of each lease year thereafter during the Lease Term
(including any extension terms), the Base Annual Rent (then in effect) shall be
increased by three percent (3%) per annum. Landlord shall give Tenant written
notice of each such adjustment and the amount of Base Annual Rent payable during
the forthcoming lease year. In lieu of the three percent (3%) escalation, the
Base Annual Rent shall be increased by one and 25/100 dollars ($1.25) per
rentable square foot at the commencement of the sixth (6th) Lease Year.

(i) General. Whenever it is provided by the terms of this Lease that
Tenant is required to make any payment to Landlord other than of Base Annual
Rent, such payment shall be deemed to be additional rent ("Additional Rent").
Unless otherwise expressly specified herein, Additional Rent

shall be paid by Tenant upon Tenant's receipt from Landlord of a statement
showing the amount owed. Additional Rent shall include, but not be limited to:

(ii) Operating Expenses. Throughout the Lease Term, Tenant agrees to
pay to Landlord, as Additional Rent, Tenant's Proportionate Share, as set forth
in Section l(a)(6), (and as may be adjusted as contemplated by Section 2(a)), of
any increase in operating expenses during each calendar year over the Base
Operating Expense Amount specified in Section l(a)(17). The term "operating
expenses" shall mean any and all expenses reasonably incurred by Landlord in
connection with owning, managing, operating, maintaining, servicing, insuring
and repairing the Building, and the attached land and parking lot, and its
related exterior appurtenances, including but not limited to: (1) wages and
salaries of all employees engaged in the management, operation or maintenance of
the Building, including taxes, insurance and benefits relating hereto; (2) all
supplies, materials, equipment and tools used in the operation or maintenance of
the Building; (3) cost of all maintenance and service agreements for the
Building and the equipment therein, including but not limited to controlled
access and energy management services, window cleaning and elevator maintenance;
(4) cost of all insurance relating to the Building, including the cost of
casualty, liability and rent loss insurance applicable to the Building and
Landlord's personal property used in connection therewith; (5) general and
special repairs and maintenance; (6) management fees; (7) legal, accounting,
auditing and other professional fees; (8) the cost of any additional services
not provided to the Building at the Commencement Date of the Lease Term, but
thereafter provided by Landlord in the prudent management of the Building; (9)
reasonable reserves for replacements, repairs and contingencies; (10) costs for
char service and cleaning supplies; (11) costs for utility services such as
electricity, gas, water and sewage (including any costs incurred in changing the
provider providing electricity services); (12) the cost of any capital
improvements or alterations made to the Building after the Commencement Date of
the Lease Term, that reduce other operating expenses, or which are required
under any governmental law or regulation that was not applicable to the Building
at the time it was constructed, such cost to be amortized over such reasonable
period as Landlord shall reasonably determine, together with interest on the
unamortized balance at the rate paid by Landlord on funds borrowed for the
purposes of constructing said capital improvements; (13) transportation district
fees, parking district fees, and the cost of other amenities required by law;
and (14) "real estate taxes" (as hereinafter defined). "Operating Expenses"
shall not include any of the following, except to the extent that such costs and
expenses are included in operating expenses as described in the previous
sentence: capital expenditures; depreciation of the Building or equipment
therein; costs of painting or decorating tenant space; leasing brokerage
commissions; interest and amortization of mortgages; ground rent; the costs of
special services or utilities separately charged to individual tenants of the
Building; or that portion of any Operating Expenses that is paid to any entity
affiliated with Landlord that is in excess of the amount that would otherwise
have been paid to a non-affiliated entity.

The term "real estate taxes" shall mean all taxes and assessments, general
and special, ordinary and extraordinary, foreseen and unforeseen, now or
hereafter assessed, levied or imposed upon the Building, and the land on which
it is built, including, without limitation, front foot benefit charges and
adequate public facility costs and assessments, together with (i) any tax,
assessment, or other imposition in the nature of a real estate tax, (ii) any ad
valorem tax on rent or any tax on income if imposed in lieu of or in addition to
real estate taxes and assessments, and (iii) any taxes and assessments which may
hereafter be substituted for real estate taxes, including by way of illustration
only, any tax, assessment or other imposition (whether a business rental or
other tax) now or hereafter levied upon Landlord for Tenant's use or occupancy
of or conduct of business at the Demised Premises, or Tenant's improvements to
or furniture, fixtures or equipment in the Demised Premises. "Real estate taxes"
shall also include all costs incurred by Landlord in contesting the validity or
amount of any such taxes.

(iii) Landlord's Enforcement Costs. Additional Rent shall include any
and all expenses incurred by Landlord, including reasonable attorneys' fees and
court costs, for the collection of monies due from Tenant and the enforcement of
Tenant's obligations under the provisions of this Lease. When Landlord, at
Tenant's expense, performs an obligation of Tenant pursuant to the terms of this
Lease, the costs and expenses (including overhead) incurred by Landlord in
performance of such obligations shall be Additional Rent.

(d) Additional Rent Estimates and Adjustments

(i) In order to provide for current monthly payments of Additional
Rent, Landlord shall submit to Tenant prior to January 1st of each year during
the Lease Term a written statement of Landlord's estimate of the amount of the
increases described in Section 4(c)(ii) above, together with the amount of
Tenant's Additional Rent which is estimated to result from such increases.
Tenant shall pay each month one-twelfth (l/12th) of Tenant's Proportionate Share
of Landlord's estimate of the increase in each year of operating expenses over
the Base Operating Expense Amount. Landlord may revise its estimate of operating
expenses at any time during a calendar year by written notice to Tenant, setting
forth such revised estimate and Tenant's Proportionate Share of the estimated
operating expense increases. In such event, all monthly payments made by Tenant
after such notice shall be in an amount calculated on the basis of such revised
estimate. Tenant shall, in all cases, continue to make monthly payments of Basic
Operating Expenses based on the last estimate from Landlord until it receives a
revised or updated estimate.

(ii) If payment of Additional Rent begins on a date other than January
1st under this Lease, in order to provide for current payments of Additional
Rent through December 31st of that partial calendar year, Landlord shall submit
to Tenant a statement of Landlord's estimate of Tenant's Additional Rent for
that partial year, stated in monthly increments, resulting from the increases
described in Section 4(c) (ii) above. Tenant shall make the monthly incremental
payments of estimated Additional Rent together with its installments of Base
Monthly Rent during that partial year.

(iii) After the end of each calendar year, Landlord will as soon as
practicable submit to Tenant a statement of the actual increases incurred in
operating expenses for the preceding calendar year over the Base Operating
Expense Amount. Tenant shall pay Landlord, within thirty (30) days of Tenant's
receipt of such statement, Tenant's Proportionate Share of the excess, if any,
of Tenant's Proportionate Share of the actual operating expense increases over
the amount paid by Tenant during the previous year as its Proportionate Share of
the projected operating expense increases. If the amount paid by Tenant during
the previous year exceeded Tenant's Proportionate Share of actual operating
expense increases for the year, the excess shall be credited toward payment of
the next installment of Base Monthly Rent to be paid by Tenant after Tenant
receives said statement from Landlord. If the amount paid by Tenant during the
last calendar year of the Lease Term exceeds Tenant's Proportionate Share of
actual operating expense increases for such year, Landlord shall pay Tenant the
excess amount within thirty (30) days after Landlord's submission to Tenant of
the aforesaid operating expense statement for such calendar year.

(iv) Within ten (10) days after receipt of Landlord's statement
showing actual figures for the year, Tenant shall have the right to request a
statement of operating expenses of the Building prepared by Landlord's certified
public accountant and copies of real estate tax bills, which shall be supplied
to Tenant within a reasonable time (not to exceed thirty (30) days) after
Tenant's written request. No such request shall extend the time for payments as
set forth in Section 4(c) or Section 4(d) (iii) above. Unless Tenant asserts
specific error(s) and supports such errors, in writing, within fifteen (15)
business days after Landlord has complied with Tenant's request, Tenant shall
waive the right to contest the statement of actual figures for the year
submitted by Landlord. If it shall be determined that there is an error in
Landlord's statement, Tenant shall be entitled to a credit for any overpayment.
Any payment, refund or credit made pursuant to Section 4(c) or 4(d) shall be
made without prejudice to any right of Tenant to dispute, or of Landlord to
correct, any item(s) as billed pursuant to the provision hereof; provided
however, such right to correct or adjust rental payments shall terminate at the
expiration of two (2) years after the date any payment shall have become due.

(e) Prorated Rent. Any rent payable for a portion of a month shall be
prorated based upon a thirty (30) day calendar month.

(f) Payment of Rent. Any Base Annual Rent or Additional Rent which is not
paid within five (5) days after the same is due shall, subject to Tenant
receiving notice as provided in Section 23(a)(i), bear interest at eighteen
percent (18%) per annum or the highest legal rate, whichever is lower. In
addition, in the event Base Annual Rent or Additional Rent is not paid within
five (5) days of its due date, Landlord, at its sole option, may assess a late
charge equal to five percent (5%) of the Base Monthly Rent as liquidated damages
for the additional administrative charges incurred by Landlord

as a result of such late payment. If Landlord receives from Tenant two or more
returned or "bounced" checks in any twelve (12) month period, Landlord may
require all future rent by cashier's or certified check.

(g) Survival of Rent Obligation. The obligation of Tenant with respect to
the payment of Additional Rent shall survive the termination of this Lease or
assignment thereof.

5. SECURITY DEPOSIT.

(a) Use. Tenant has deposited with Landlord simultaneously with the
execution of this Lease, the amount stipulated in Section 1(a)(l6) as a deposit
(the "Security Deposit") to secure the prompt performance of Tenant's
obligations hereunder. The Security Deposit may be commingled with Landlord's
general funds, if permitted by law. Landlord shall have the right, but shall not
be obligated, to apply all or any portion of the Security Deposit to cure any
Default or to compensate Landlord for loss or damage sustained by Landlord as a
result of a Default, in which event Tenant shall be obligated to deposit with
Landlord the amount necessary to restore the Security Deposit to its original
amount within ten (10) business days after written notice from Landlord. To the
extent not forfeited or otherwise used as provided herein, and provided the
Demised Premises are vacated in good condition, reasonable wear and tear
excepted, as described in Section 11, the Security Deposit shall be returned,
without interest, to Tenant within forty-five (45) days after the expiration or
termination of this Lease.

or any assignee of Landlord's interest in the Demised Premises or the Building,
whereupon Landlord shall be discharged from any further liability with respect
to the Security Deposit. This provision shall apply also to any and all
subsequent transferors of the Landlord's interest in this Lease.

(c) Not Liquidated Damages. If the Tenant fails to take possession of the
Demised Premises as required by this Lease, the Security Deposit shall not be
deemed liquidated damages and Landlord's use of the Security Deposit pursuant to
this Section 5 shall not preclude Landlord from recovering from Tenant all
additional damages incurred by Landlord.

which, in Landlord's sole discretionary opinion, impair the reputation of the
Building. Tenant shall refrain from and discontinue such use immediately upon
receipt of written notice from Landlord. Tenant, at its expense, shall comply
with the laws, rules or regulations now or hereinafter enacted of any federal,

or modifications to the Demised Premises which are necessitated or required by
any such laws, rules, regulations or notices.

(c) Environmental Protection. During the Lease Term, Tenant and Tenant's
employees and agents shall not dispose of any oil, petroleum or chemical liquids
or solids, liquid or gaseous products or any hazardous waste or hazardous

Environmental Response, Compensation, and Liability Act of 1980, or in any other
federal, state or local law governing hazardous substances, as such laws may be
amended from time to time (hereinafter collectively referred to as the "Act"),
at, upon, under or within the Demised Premises or the Building or the land upon
which it is built or into the plumbing or sewer or water system servicing the
Demised Premises and/or the Building, nor shall Tenant, its agents or employees
cause or permit the discharge, spillage, uncontrolled loss, seepage or

Demised Premises or the Building or the land, Tenant shall give immediate notice
to the Landlord of same and promptly, at Tenant's sole expense, take any and all
necessary actions to return the Demised Premises and the Building and the land
to the condition existing before the presence of any such hazardous waste,
provided, however, that Tenant shall first obtain Landlord's written approval
for any such remedial action.

(d) Indemnification. Tenant shall indemnify, defend and hold harmless
Landlord from and against all costs, expenses, liabilities, losses, damages,
injunctions, suits, fines, penalties, claims, and demands including reasonable
attorneys' fees, arising out of any violation of or default in the covenants of
Sections 7(b) and (c). The provisions of Sections 7(b) and (c) and this Section

8. RULES AND REGULATIONS.

Tenant covenants on behalf of itself, its employees, agents, and licensees
and invitees to comply with the rules and regulations set forth in Exhibit "D",
which is attached hereto and made a part hereof (the "Rules and Regulations").
Landlord shall have the right, in its sole discretion, to make reasonable
additions and amendments to the Rules and Regulations from time to time and
Tenant covenants that Tenant, its employees, agents, licensees and invitees will
comply with additions and amendments to the Rules and Regulations upon
Landlord's provision to Tenant of a written copy of the same. Any default by
Tenant, or any other party set forth above, of any of the provisions of the
Rules and Regulations as set forth on Exhibit "D" or as amended, from time to
time, shall be considered to be a Default under the terms of this Lease.
Landlord shall have no liability to Tenant or any other party for violations of
the Rules and Regulations by any party whatsoever. If there is any inconsistency
between this Lease and the Rules and Regulations, the Lease shall govern.

9. SUBLETTING AND ASSIGNMENT.

(a) Consent. Tenant shall not assign this Lease, or any of Tenant's rights
or obligations hereunder, or sublet the Demised Premises or any part thereof, or
permit the Demised Premises to be used by others without the prior written
consent of Landlord, which consent shall not be unreasonably withheld if all of
the following conditions are satisfied:

(i) In the reasonable judgment of Landlord, the proposed assignee or
subtenant is of a character and financial worth such as is in keeping with the
standards of Landlord in those respects for the Building, and the nature of the
proposed assignee's or subtenant's business and its reputation are in keeping
with the character of the Building and its tenancies;

(ii) The purposes for which the proposed assignee or subtenant intends
to use the Demised Premises (or the applicable portion thereof) are uses
permitted by this Lease and not prohibited by any other lease in the Building;

(iii) No uncured default shall have occurred under this Lease, either
at the time Landlord's consent to such assignment or subletting is requested, or
at the commencement of the term or effective date of such assignment or
subletting, and Tenant shall comply with all of the terms of this Section 9 in
connection with such assignment or subletting;

(iv) In the event of an assignment, the proposed assignee shall assume
all of Tenant's obligations under this Lease, by agreement reasonably
satisfactory to Landlord;

(v) In the event of a subletting, the proposed subtenant shall agree
to perform Tenant's obligations hereunder with respect to the portion of the
Demised Premises sublet, by agreement reasonably satisfactory to Landlord; and

(vi) Any Building mortgagee whose consent is required shall consent to
such assignment or subletting.

If Tenant is a corporation, unincorporated association, partnership or limited
liability company, then the transfer, assignment or hypothecation of any stock
or interest in such corporation, association, partnership or limited liability
company so as to result in a change in the control thereof by the person,
persons or entities owning a controlling interest therein as of the date of this
Lease, without the prior written consent of Landlord as described above, shall
be deemed an assignment made in breach of this covenant. Tenant shall not
mortgage, pledge or encumber this Lease without Landlord's prior written
consent, which may be granted or withheld in Landlord's sole discretion.
Landlord's consent in any specific instance to any assignment, mortgage, pledge,
encumbrance, subletting or use of the Demised Premises and its collection and
acceptance of rent from any such approved assignee, subtenant or other occupant
shall neither constitute a waiver of the provisions of this paragraph, nor be
construed as permission for any subsequent assignment, mortgage, encumbrance,
subletting or use without compliance with this paragraph. Without the prior
written consent of Landlord, this Lease and the interest of Tenant, or any
assignee of Tenant, shall not pass

by operation of law, nor shall it be subject to garnishment or sale under
execution in any suit or proceeding which may be brought against or by Tenant,
or any assignee of Tenant.

(b) Request for Consent. In order to request the consent of Landlord to an
assignment of this Lease or subletting of all or part of the Demised Premises,
Tenant shall give Landlord written notice ("Tenant's Request Notice") of the
identity of the proposed assignee or subtenant and its business, all terms of
the proposed assignment or subletting, the commencement or effective date of the
proposed assignment or subletting (the "Proposed Transfer Commencement Date",
which shall not be less than sixty (60) days after the date of Tenant's Request
Notice), and the area proposed to be assigned or sublet (the "Proposed Transfer
Space"). Tenant shall also transmit therewith the most recent financial
statement or other evidence of financial responsibility of such assignee or
subtenant, a certification executed by Tenant and such proposed assignee or
subtenant stating whether (and to what extent) any premium or other
consideration is being paid for the proposed assignment or subletting, and all
other information reasonably requested by Landlord concerning such proposed
assignee or subtenant. Tenant shall pay all expense (including reasonable
attorneys' fees) up to $1,000.00 incurred by Landlord in connection with any
request by Tenant for Landlord's consent to any assignment, subletting,
mortgage, pledge or encumbrance.

(c) Landlord's Termination Right. Except in the event of an assignment of
Lease which is triggered by an acquisition of Tenant by another entity, Landlord
shall have the right in its sole and absolute discretion to terminate this Lease
with respect to the Proposed Transfer Space as of the Proposed Transfer
Commencement Date, by sending Tenant written notice within thirty (30) days
after Landlord's receipt of Tenant's Request Notice. If the Proposed Transfer
Space does not constitute the entire Demised Premises and Landlord elects to
terminate this Lease with respect to the Proposed Transfer Space, then: (i)
Tenant shall tender the Proposed Transfer Space to Landlord on the Proposed
Transfer Commencement Date as if the Proposed Transfer Commencement Date had
been originally set forth in this Lease as the expiration date of the Lease Term
with respect to the Proposed Transfer Space; and (ii) as to all portions of the
Demised Premises other than the Proposed Transfer Space, this Lease shall remain
in full force and effect, and the Base Annual Rent and Tenant's Proportionate
Share shall be reduced proportionately based on square footage. Unless otherwise
agreed in writing, Tenant shall pay all expenses of demising walls and other
construction required to permit the operation of the Proposed Transfer Space
separate from the balance of the Demised Premises. If the Proposed Transfer
Space constitutes the entire Demised Premises and Landlord elects to terminate
this Lease, then: (i) Tenant shall tender the Demised Premises to Landlord on
the Proposed Transfer Commencement Date, and (ii) the Lease Term shall terminate
on the Proposed Transfer Commencement Date. If Landlord exercises its right to
terminate this Lease with respect to the Proposed Transfer Space (whether the
Proposed Transfer Space constitutes all or part of the Demised Premises, Tenant
agrees that Landlord shall have access to the Proposed Transfer Space thirty
(30) days prior to the effective termination date for remodeling or redecorating
purposes, or to show the Proposed Transfer Space to prospective tenants.

(d) Profits. In the event of an assignment or sublease made in accordance
with the terms hereof, Tenant shall pay to Landlord monthly (in the case of a
sublease) or when otherwise received by Tenant (in the case of an assignment)
fifty percent (50%) of the "Net Profits" (as defined herein) received by Tenant
in connection with such assignment or sublease. "Net Profits" is defined as the
excess of the rent and/or all other sums collected by Tenant under or in
connection with such an assignment or sublease over and above the Base Annual
Rent and Additional Rent payable by Tenant to Landlord under this Lease for the
space covered by such assignment or sublease (which shall be the pro rata
portion of the total Base Annual Rent and Additional Rent payable hereunder in
the case of a sublease of a portion of the Demised Premises) and the direct, out
of pocket costs incurred by Tenant in performing alterations or leasehold
improvements for the assignee or subtenant and the leasing commissions paid by
Tenant in connection with such assignment or sublease.

(e) Tenant Liability. Except as set forth in 9(c) above, in the event of
any subletting of the Demised Premises or assignment of this Lease by Tenant,
with or without Landlord's consent, Tenant shall remain liable to Landlord for
payment of the Base Annual Rent and Additional Rent stipulated herein and all
other covenants and conditions contained herein. Tenant assigns to Landlord any
rents due from any subtenant as security for Tenant's performance of its
obligations under this Lease. Upon a Default by Tenant, Tenant authorizes each
of its subtenants to pay such rents directly to Landlord if such subtenant
receives written notice from Landlord specifying that such rents shall be paid
directly to Landlord. Landlord shall copy Tenant on any such notice.

(f) Assignment by Landlord. It is understood and agreed that this Lease and
all rights of Landlord hereunder shall be fully and freely assignable by
Landlord without notice to, or consent of, Tenant. In the event of the transfer
and assignment by Landlord of its interest in this Lease, Landlord shall thereby
be released from any responsibility for obligations accruing hereunder after the
date of such transfer, and Tenant agrees to look solely to such successor in
interest of the Landlord for performance of such obligations. The term
"Landlord" as used in this Lease shall mean the owner of the Building at the
time in question. In the event of a transfer (whether voluntary or involuntary)
by such owner of its interest in the Building, such owner shall thereupon be
released and discharged from all covenants and obligations of the Lease
thereafter accruing, but such covenants and obligations shall be binding during
the Lease Term upon each new owner for the duration of such owner's ownership.

10. SERVICES AND UTILITIES.

(a) Building Standard Services and Utilities. Landlord shall furnish
sufficient electric current for routine and normal requirements for lighting and
typical office equipment and machinery, such as typewriters, calculators,
personal computers, small copiers and similar items, subject to the limitations
of Section 10(b), water for lavatory and drinking purposes, common area lavatory
supplies, Building standard four foot (4') fluorescent tube replacements,
automatically operated elevator service, and nightly cleaning and janitorial
services Monday through Friday, all without additional cost to Tenant. Landlord
further agrees to furnish heating and cooling during the appropriate seasons of
the year, between the hours and on the days set forth in Section 1(a)(20),
exclusive of the Building Holidays specified in Section l(a)(21), with holidays
falling on Saturday observed both on said day and on the preceding Friday, and
holidays falling on Sunday observed on the following Monday. During Standard
Building Operating Hours, the temperature within the Demised Premises shall be
maintained within the range from a minimum of sixty-eight (68) degrees
fahrenheit during winter months to a maximum of seventy-eight (78) degrees
fahrenheit during summer months.

(b) Overtime Services. Should Tenant require heating, ventilating and air
conditioning ("HVAC") services beyond the hours stipulated in Section 10(a),
Landlord will furnish such additional service at the then-prevailing hourly
rate, as established by Landlord from time to time, provided that Tenant gives
Landlord no less than twenty-four (24) hours advance written notice of the need
therefor.

(c) Interruption or Reduction of Service. In no event shall Landlord be
liable to Tenant for any interruption or failure in the supply of any utilities
to the Demised Premises. Landlord reserves the right to interrupt service of the
heat, plumbing, air conditioning, cooling, electric, and sewer and water
systems, when necessary, by reason of accident, or of repairs, alterations,
improvements or changes from one utility provider to another, which in the
judgment of Landlord are desirable or necessary to be made, until such repairs,
alterations or improvements shall have been completed; and Landlord shall have
no responsibility or liability for failure to supply heat, plumbing, air
conditioning, cooling, electric, or sewer and water service, or any other
service or act for the benefit of Tenant, when prevented from so doing by
strikes, accidents or by any other causes beyond Landlord's reasonable control,
or by orders or regulations of any federal, state, county, or municipal
authority, or by any failure to receive suitable fuel supply, or inability
despite exercise of reasonable diligence to obtain the regularly-used fuel or
other suitable substitute; and Tenant agrees that Tenant shall have no claim for
damages nor shall there be any abatement of Base Annual Rent or Additional Rent
in the event that any of said systems or service shall be discontinued or shall
fail to function for any reason. If any public utility supplying any utility to
the Building, or any law, order or regulation of any federal, state, county or
municipal authority requires that Landlord or Tenant must reduce or maintain a
certain level of consumption of electricity or any other utility, or reduce or
increase the interior temperature of the Demised Premises or the Building, then
Landlord and Tenant shall each abide by such requirement without any reduction
in Base or Additional Rent or in any of Tenant's other obligations hereunder. In
the event of an interruption, reduction or failure in the supply of any
utilities to the Demised Premises for a period exceeding ten (10) consecutive
business days due to causes beyond Landlord's reasonable control as herein
described, then Tenant shall be entitled to a rental abatement for that period
of time in which there occurred an interruption, reduction or failure in the
supply of utilities.

(d) Excessive Electrical Usage.

(i) Tenant will not install or operate in the Demised Premises any
"heavy duty electrical equipment or machinery", without obtaining the prior
written consent of Landlord. "Heavy duty electrical equipment or machinery"
shall mean any equipment or machinery which draws in excess of thirty (30) amps.
Landlord may require, as a condition of its consent to the installation of such
equipment or machinery, payment by Tenant, as Additional Rent, for such excess
consumption of electricity as may be occasioned by the operation of said
equipment or machinery. Landlord may make periodic inspections of the Demised
Premises at reasonable times to determine that Tenant's electrically operated
equipment and machinery complies with the provisions of this Section and Section
10(e).

(ii) Landlord shall have the right to require that one or more
separate meters or submeters be installed to record the consumption or use of
electricity, or to cause a reputable independent electrical engineer to survey
and determine the quantity of electricity consumed by such excessive use. The
cost of any such survey or meters and of installation, maintenance and repair
thereof shall be paid by Tenant. Tenant agrees to pay Landlord (or the utility
company, if direct service is provided by the utility company), promptly upon
demand therefor, for all such electricity consumption as shown by said meters,
or a flat monthly charge determined by the survey, as applicable, at the rates
charged for such service by the local public utility company. If Tenant's cost
of electricity based on meter readings is to be paid to Landlord, Tenant shall
pay a service charge related thereto.

(e) Excessive Heat Generation. Landlord shall not be liable for its failure
to maintain comfortable atmospheric conditions in all or any portion of the
Demised Premises, due to heat generated by any equipment or machinery installed
by Tenant (with or without Landlord's consent) that exceeds generally-accepted
engineering design practices for normal office purposes. If Tenant desires
additional cooling to offset excessive heat generated by such equipment or
machinery, Tenant shall pay for auxiliary cooling equipment and its operating
costs, including without limitation electricity, gas, oil and water, or for
excess electrical consumption by the existing cooling system, as appropriate.

(f) Security. Any security measures that Landlord may undertake are for
protection of the Building only and shall not be relied upon by Tenant to
protect Tenant, its property, its employees or their property.

(g) Utility Selection. Landlord may, at any time, in its sole discretion,
change the utility provider which provides electricity or any other utility
service to the Building. In the event of such change, Tenant shall cooperate
with Landlord and allow access to the Demised Premises for purposes of
effectuating such change.

11. MAINTENANCE AND REPAIRS.

(a) Tenant Reporting Requirements. Tenant agrees to report immediately to
Landlord's Tenant Services Desk (301-417-6175 or
Servicerequest@guardian-realty.com) any defective condition in or about the
Demised Premises known to Tenant which Landlord is required to repair, and a
failure to so report shall make Tenant liable to Landlord for any additional or
increased expenses, damages or liability resulting from such failure to report
the defective condition.

(b) Landlord Responsibilities. Landlord shall make structural repairs to
the Demised Premises necessary for safety and tenantability, and shall maintain
and repair all Building equipment serving the Demised Premises and all exterior
plate glass in the Demised Premises, and the cost of all such repairs or
maintenance shall be included in Building operating expenses unless necessitated
by the act or omission of Tenant, its agents, employees, licensees, invitees or
contractors, in which event Tenant shall pay such cost to Landlord, as
Additional Rent, promptly upon demand. Tenant agrees to report immediately in
writing to Landlord any defective condition in or about the Demised Premises
known to Tenant which Landlord is required to repair, and a failure to so report
shall make Tenant liable to Landlord for any expense, damage or liability
resulting from such defects. Tenant waives the right to make repairs at
Landlord's expense under any law, statute or ordinance now or hereafter in
effect.

(c) Americans with Disabilities Act. Within ten (10) days after receipt,
Tenant shall advise Landlord in writing, and provide copies of (as applicable)
any notices alleging violation of the Americans with Disabilities Act of 1990
("ADA") relating to any portion of the Demised Premises or the Building, any
claims made or threatened in writing regarding noncompliance with the ADA and
relating to any portion of the Demised Premises or the Building, or any
governmental or regulatory actions or investigations instituted or threatened
regarding noncompliance with the ADA and relating to any portion of the Demised
Premises or the Building.

(d) Tenant Responsibilities. Tenant will keep the Demised Premises and the
fixtures and equipment therein in good order and condition, will take good care
thereof and will suffer no waste or damage thereto. At the expiration or other
termination of the Lease Term, Tenant will surrender the Demised Premises broom
clean and in as good order and condition in which they were on the Rent
Commencement Date, ordinary wear and tear excepted. All repairs and maintenance
required to be performed by Tenant shall be made or performed upon the
occurrence of the necessity therefor, and shall be made or performed in a good
and workmanlike manner, using Building standard materials, by a contractor
approved by Landlord and bonded unless waived by Landlord, and shall be made or
performed in accordance with (i) all laws and all applicable governmental codes
and requirements, and (ii) insurance requirements set forth in this Lease or
otherwise established by Landlord. Maintenance, repair and replacement of
dedicated fixtures and equipment such as kitchen fixtures, auxiliary
air-conditioning equipment and humidity control equipment dedicated exclusively
for the use of the Demised Premises, private bathroom fixtures and any other
type of special equipment, together with related plumbing or electrical
services, whether installed by Tenant or by Landlord on behalf of Tenant, shall
be the sole responsibility of Tenant, and Landlord shall have no obligation in
connection therewith. Tenant shall be responsible for the replacement of all
light bulbs and tubes in the Demised Premises except Building Standard four foot
(4') fluorescent tubes. If Tenant refuses or neglects to promptly commence and
complete repairs or maintenance necessary to satisfy the provisions of this
Section, the Landlord may, but shall not be required to, make and complete said
repairs or maintenance and Tenant shall pay the cost therefor (including
overhead) to Landlord upon receipt of an invoice therefore, detailing all such
expenses, as Additional Rent. Upon Tenant's written request to Landlord,
Landlord's agent may elect to perform certain repairs, maintenance and
installation in and to the Demised Premises, which are either desired by Tenant
or required to be performed by Tenant as set forth herein. Upon such request by
Tenant, Landlord would provide to Tenant an estimate of the cost for such work.
Upon completion of such work, Tenant shall (unless the cost of the repair is
otherwise covered by a warranty referred to in Section 6(a)) pay all costs in
connection with such repairs, maintenance and installation, which costs shall
include, but not be limited to labor, materials and a management fee (as
determined by Landlord's agent and subject to change from time to time.) If
Tenant contracts with Landlord's agent to act as its general contractor with
respect to any repairs, maintenance or installations during the term of the
Lease, then Tenant shall have the benefit of all warranties for workmanship
provided by any third- party contractor or vendor retained by Landlord's agent
and any other applicable manufacturer's warranties for materials and equipment
furnished to Tenant by such third-party contractor or vendor. Neither Landlord,
nor Landlord's agent shall have any liability to Tenant in connection with such
repairs, maintenance and installation.

(e) Landlord's Reserved Rights. Landlord reserves the right at any time and
from time to time, as often as Landlord deems desirable, without the same
constituting an actual or constructive eviction and without incurring any
liability to Tenant or otherwise affecting Tenant's obligations under this
Lease, to make changes, alterations, additions, improvements, repairs,
relocations or replacements in or to the Building and the fixtures and equipment
thereof, as well as in or to the street entrances, halls, passages, stairways
and other common facilities thereof, and to change the name by which the
Building is commonly known and/or the Building's address. Landlord reserves the
right from time to time to install, use, maintain, repair and replace pipes,
ducts, conduits, wires and appurtenant meters and equipment for service to other
parts of the Building, above the ceiling surfaces, below the floor surfaces,
within the walls and in the central core areas, and to relocate any pipes,
ducts, conduits, wires and appurtenant meters and equipment included in the
Demised Premises which are located in the Demised Premises or located elsewhere
outside the Demised Premises, and to expand and/or build additional stories on
the Building. Landlord further reserves the right at any time to alter, expand
or reduce the parking facilities, to change the means of ingress thereto and
egress therefrom, and to impose charges for parking in such facilities. Nothing
contained herein shall be deemed to relieve Tenant of any duty, obligation or
liability with respect to making

any repair, replacement or improvement or complying with any law, order or
requirement of any government or other authority and nothing contained herein
shall be deemed or construed to impose upon Landlord any obligation,
responsibility or liability whatsoever, for the care, supervision or repair of
the Building, or any part thereof, other than as expressly provided in this
Lease.

12. ALTERATIONS.

(a) Landlord Consent. Tenant will not make any alterations, installations,
changes, replacements, additions or improvements, structural or otherwise
(collectively, "Alterations") in or to the Demised Premises or any part thereof,
without the prior written consent of Landlord, which may be granted or withheld
for structural Alterations and Alterations which would be visible from the
exterior of the Building. Any construction up-gradings required by any
governmental authority as a result of said Alterations, either in the Demised
Premises or in any other part of the Building, will be paid for by Tenant.
Tenant shall not install any equipment of any nature whatsoever which may affect
the insurance rating of the Building, or which may necessitate any changes,
replacements or additions to the plumbing system, heating system,
air-conditioning system or the electrical system of the Demised Premises,
without the prior written consent of Landlord, which may be granted or withheld
in Landlord's sole discretion. Tenant shall pay all costs to make such changes,
replacements or additions. Any approved Alterations shall be made by licensed
and bonded contractors and mechanics approved by Landlord, in accordance with
(i) the applicable laws and ordinances of any public authority having
jurisdiction over the Building, (ii) the building code and zoning regulations of
any such authority, and (iii) any rules and regulations established from time to
time by the Underwriters Association of the local area. Prior to commencing
construction of any approved Alteration, Tenant shall obtain any necessary
building permits and shall deliver copies of such permits to Landlord. Landlord,
in Landlord's sole discretion, may require as a condition precedent to the
commencement of construction of any Alterations that Tenant furnish evidence to
Landlord that Tenant and Tenant's contractors carry insurance as specified in
Sections 19(b)and 19(d) hereof and such additional insurance as Landlord may
reasonably require. All Alterations shall be performed in a good and workmanlike
manner, using building standard materials. All Alterations shall be performed
without interference with the work or business operations of Landlord or of the
other tenants of the Building. Tenant and Tenant's contractors shall be
responsible for the transportation, safe-keeping and storage of materials and
equipment used in the performance of Alterations and for the removal of waste
and debris resulting from the performance of Alterations (it being agreed that
prior to removal, all such materials, equipment, waste and debris shall be
stored safely by Tenant within the Demised Premises).

b) Surrender. All Alterations, including without limitation wall-to-wall
carpet, blinds, draperies and drapery accessories, to or within the Demised
Premises (whether made with or without Landlord's consent), shall remain upon
the Demised Premises and be surrendered with the Demised Premises at the
expiration of the Lease Term without disturbance, molestation or injury, unless
otherwise specified by Landlord. Should Landlord elect that any Alterations made
by Tenant upon the Demised Premises be removed upon the expiration of the Lease
Term, Tenant agrees that Landlord shall have the right to cause same to be
removed at Tenant's sole cost and expense. Tenant agrees to reimburse Landlord
for the cost of (i) such removal, (ii) repairing any damage resulting therefrom,
and (iii) restoring the Demised Premises to its condition at the commencement of
the Lease Term as initially improved by Landlord, ordinary wear and tear
excepted. Landlord shall perform its final inspection and walk-thru with Tenant
promptly after Tenant's surrender of the Demised Premises.

(c) Liens. In making any approved Alterations, Tenant shall promptly pay
all contractors, materialmen and laborers, so as to minimize the possibility of
a lien attaching to the Building, or attaching to any portion of the real
property on which the Building is located. Should any such lien be filed, Tenant
shall bond against or discharge the same within ten (10) days after the said
filing. If Tenant shall fail to bond against or discharge any such lien within
such ten (10)-day period, then Landlord may, at its option, discharge such lien
at Tenant's expense in which event Tenant shall reimburse Landlord for all costs
(including legal expenses) of discharging such lien upon demand, as Additional
Rent.

(d) Indemnity. Tenant will defend, indemnify and hold Landlord harmless
from and against any and all expenses, liens, claims or damages, including
attorneys' fees, for injury to person or property which may or might arise,
directly or indirectly, by reason of the making of any Alterations.

If any Alteration is effected without the prior written consent of Landlord,
Landlord may remove or correct the same and Tenant shall be liable for any and
all expenses of this work. All rights given to Landlord herein shall be in
addition to any other right or remedy of Landlord contained in this Lease.

13. SIGNS AND ADVERTISEMENTS.

(a) Directory Listings and Suite Entrance Signs. Landlord agrees to
display, at Landlord's expense, Tenant's name on the Building directory or
directories in the size and style or lettering used by Landlord. The number of
individual names listed on the Building directory or directories shall be
subject to such limitation as shall be established from time to time by
Landlord. Tenant may display its name on the corridor wall adjacent to the
Demised Premises, as directed by Landlord, in Building standard color, size and
style of lettering, to be furnished by Landlord at Landlord's expense.

(b) Landlord Consent. No sign, advertisement or notice shall be inscribed,
painted, affixed or displayed on any part of the outside or the inside of the
Building, or inside of the Demised Premises where it may be visible from outside
or from the public areas of the Building, except with Landlord's prior written
consent and then only in such location, number, size, color and style (i.e.,
Building standard lettering) as is authorized by Landlord. If any such sign,
advertisement or notice is exhibited without Landlord's written consent,
Landlord shall have the right to remove same, and Tenant shall be liable for any
and all expenses incurred by Landlord in connection with said removal.

(c) Exterior Signs. In the event Landlord shall permit Tenant to install a
sign on the exterior of the Building, Tenant shall obtain Landlord's written
approval of the plans and specifications for such sign. After construction and
prior to installation of said sign, Tenant shall present the same to Landlord
for its written approval, which approval shall not be withheld so long as the
sign conforms fully to the approved plans and specifications. Tenant shall
install its approved sign at a time mutually agreed upon by Landlord and Tenant,
it being understood and agreed that Landlord shall have the right to supervise
such installation. Throughout the Lease Term, Tenant shall maintain such sign in
good condition and repair. Upon the termination or expiration of the Lease Term,
Tenant shall remove such sign, repair any damage occasioned by such removal, and
restore the area of the Building on which such sign was installed to its
condition prior to the installation of such sign. If Tenant fails to do so,
Landlord may do so at Tenant's expense and Tenant shall pay the cost therefor
(including overhead) to Landlord upon demand, as Additional Rent. Tenant's
obligations under this Section 13(c) shall survive the termination or expiration
of this Lease.

(d) Advertisements. Tenant shall not publish any advertisement which refers
to, displays or utilizes in any way the Demised Premises, the Landlord or the
Building without the prior review and written consent of Landlord.

14. EXCESSIVE FLOOR LOAD.

Landlord shall have the right to prescribe the weight and method of
installation and position of safes or other heavy fixtures or equipment. Tenant
will not, without Landlord's prior written approval, install in the Demised
Premises any fixtures, equipment or machinery that will place a load upon the
floor exceeding the designed floor load capacity. The floor load capacity for
the Demised Premises is 100 lbs per square foot (PSF) Uniform Load. The floor
load capacity for the loading dock is 125 lbs per square foot (PSF) Uniform
Load. Tenant shall be liable for all damage done to the Building by installing
or removing a safe or any other article of Tenant's office equipment, or due to
its being in the Demised Premises. Landlord shall repair any such damage at
Tenant's expense, and Tenant shall pay the cost therefor to Landlord upon
demand, as Additional Rent.

15. MOVING AND DELIVERIES.

No freight, furniture or other bulky matter of any description shall be
received into the Building or carried in the elevators, except at times and by
routes authorized by Landlord. Tenant shall give Landlord at least forty-eight
(48) hours telephonic notice prior to moving any freight, furniture or other
bulky material into or out of the Building. All moving of furniture, material
and equipment shall be under the direct control and supervision of Landlord, who
shall, however, not be responsible for any damage to or charges for moving same.
Tenant shall promptly remove from the public areas within or adjacent to the
Building any of Tenant's property delivered or deposited there, and shall be

responsible for any damage to the Building or the Demised Premises caused by its
moving and deliveries.

16. TENANT'S RESPONSIBILITY FOR DAMAGE.

Any and all injury, breakage or damage of any type whatsoever to the
Demised Premises or to other portions of the Building, arising from any act or
omission of Tenant or its agents, employees, licensees, invitees or contractors,
shall be repaired by Landlord at the sole expense of Tenant. Tenant shall
reimburse Landlord for the costs for such repairs within ten (10) days of
receipt of written notice from Landlord detailing any such costs. This provision
shall be construed as an additional remedy granted to Landlord and not in
limitation of any other rights and remedies which Landlord may have in said
circumstances.

17. Access.

(a) Access to Building. Tenant shall have access to the building
twenty-four (24) hours per day, seven (7) days per week, by means of a key or an
electronic controlled access system. Landlord reserves the right to require a
refundable deposit on building keys and controlled access cards, which deposit
shall be returned to Tenant at the time such keys and cards are returned to
Landlord. Additional keys or controlled access cards required by Tenant for any
reason will be provided upon Tenant's payment of a fee as determined by
Landlord.

(b) Landlord's Access to Demised Premises. Landlord, its agents, employees
and contractors shall have the right to enter the Demised Premises at all
reasonable times, including emergencies determined by Landlord, (i) to make
inspections or to make repairs to the Demised Premises or other premises as
Landlord may deem necessary; (ii) to perform nightly cleaning of the Demised
Premises; (iii) to exhibit the Demised Premises to prospective tenants during
the last nine (9) months of the Lease Term; and (iv) for any purpose whatsoever
relating to the safety, protection or preservation of the Building. Landlord
shall use reasonable efforts to minimize interference to Tenant's business when
making repairs, but Landlord shall not be required to perform the repairs at any
time other than during normal working hours.

(c) Restricted Access. No additional locks, other devices or systems,
including without limitation alarm systems, which would restrict access to or
within the Demised Premises shall be placed upon any doors without the prior
written consent of Landlord. Unless access to the Demised Premises is provided
during the hours when cleaning service is normally rendered, Landlord shall not
be responsible for providing such service to the Demised Premises or to those
portions thereof which are inaccessible. Such inability by Landlord to provide
cleaning service to inaccessible areas shall not entitle Tenant to any
adjustment in Base Rent or Additional Rent.

18. LIABILITY.

(a) Landlord's Liability. Landlord, Landlord's Rental Agent and their
respective employees and agents shall not be liable to Tenant, any invitee or
any other person or entity for any damage (including indirect and consequential
damage), injury, loss or claim (including claims for the interruption of or loss
to business) based on or arising out of any cause whatsoever (except as
otherwise provided in this Section), including without limitation the following:
repair to any portion of the Demised Premises or the Building, interruption in
the use of the Demised Premises or any equipment therein, any accident or damage
resulting from any use or operation (by Landlord, Tenant or any other person or
entity) of elevators or heating, cooling, electrical, sewerage or plumbing
equipment or apparatus; termination of this Lease by reason of damage to the
Demised Premises or the Building; fire, robbery, theft, vandalism, mysterious
disappearance or any other casualty; actions of any other tenant of the Building
or of any other person or entity; failure or inability to furnish any service or
utility specified in this Lease; and leakage in any part of the Demised Premises
or the Building from water, rain, ice or snow that may leak into, or flow from,
any part of the Demised Premises or the Building, or from drains, pipes or
plumbing fixtures in the Demised Premises or the Building. If any condition
exists that may be the basis of a claim of constructive eviction, then Tenant
shall give Landlord written notice thereof and a reasonable opportunity to
correct such condition, and in the interim Tenant shall not claim that it has
been constructively evicted or is entitled to a rent abatement. Any property
placed by Tenant, its agents, employees or invitees in or about the Demised
Premises or the Building shall be at the sole risk of Tenant, and Landlord shall

not in any manner be responsible therefor. Notwithstanding the foregoing
provisions of this Section, and except as otherwise set forth in Section 17(b),
Landlord shall not be released from liability to Tenant for any physical injury
to any natural person or any property damage caused by Landlord's gross
negligence or willful misconduct, to the extent such injury is not covered by
insurance (i) carried by Tenant or such person, or (ii) required by this Lease
to be carried by Tenant.

(b) Criminal Acts of Third Parties. Landlord shall not be liable in any
manner to Tenant, its agents, employees, licensees or invitees for any injury or
damage to Tenant, Tenant's agents, employees, licensees or invitees or their
property caused by the criminal or intentional misconduct of third parties. All
claims against Landlord for any such damage or injury are hereby expressly
waived by Tenant, and Tenant hereby agrees to hold harmless and indemnify
Landlord from the expense of defending all claims made by Tenant's agents,
employees, licensees or invitees arising out of such acts.

(c) Indemnity. Tenant shall reimburse Landlord for, and shall indemnify,
defend upon request and hold Landlord, Landlord's Rental Agent, and their
respective agents and employees harmless from and against any and all claims,
actions, damages, liabilities, expenses (including attorneys' fees and court
costs) and losses suffered by or claimed against Landlord, directly or
indirectly, based on or arising out of, in whole or part: (i) any occurrence in,
upon or at the Demised Premises (unless caused by Landlord's gross negligence or
willful misconduct); (ii) the use and occupancy of the Demised Premises or the
business conducted therein; (iii) any act or omission of Tenant, its agents,
employees, contractors, invitees or licensees, whether inside the Demised
Premises or elsewhere in or upon the Building or the land upon which it is
built; or (iv) any breach of Tenant's obligations under this Lease, including
failure to surrender the Demised Premises upon the expiration or earlier
termination of the Lease Term. Tenant's obligations under this Section 18(c)
shall survive the expiration or other termination of the Lease Term.

19. INSURANCE.

(a) Insurance Rating. Tenant will not conduct or permit to be conducted any
activity, or place any equipment or property in or around the Demised Premises,
that will increase in any way the rate of fire insurance or other insurance on
the Building, unless consented to by Landlord in writing. Landlord's consent may
be conditioned upon Tenant's payment of any costs arising directly or indirectly
from such increase. If any increase in the rate of fire insurance or other
insurance on the Building is stated by any insurance company or by the
applicable Insurance Rating Bureau to be due to Tenant's activity, equipment or
property in or around the Demised Premises, said statement shall be conclusive
evidence that the increase in such rate is due to such activity, equipment or
property, and Tenant shall be liable for such increase. Any such rate increase
and related costs incurred by Landlord shall be deemed Additional Rent, due and
payable by Tenant to Landlord upon receipt by Tenant of a written statement
detailing the rate increase and costs. Tenant may contest, at its sole cost and
expense, any insurance rate increase, provided such action by Tenant will not
adversely affect the insurance coverage of Landlord, and that Tenant pays
Landlord the increased cost during the pendency of such a contest.

(b) Liability Insurance. Tenant agrees, at its sole cost, to carry and keep
in full force and effect at all times during the term of this Lease for the
protection of Landlord and Tenant, a broad form commercial general liability
policy insuring against any and all liability for injury to or death of a
person, or persons, and for damage to or destruction of property occasioned by
or arising out of or in connection with the use or occupancy of the Demised
Premises, or by the condition of the Demised Premises, the limits of such policy
to be in an amount not less than One Million Dollars ($1,000,000.00) per
occurrence and Two Million Dollars ($2,000,000.00) in the aggregate. Said policy
shall insure performance by Tenant of the indemnity provisions of Section 18(c),
and shall contain an assumed contractual liability endorsement that refers
expressly to this Lease. Landlord, Landlord's mortgagees designated by Landlord
and Landlord's Rental Agent shall be named as additional insureds. Tenant shall
increase its commercial general liability insurance coverage as required not
more frequently than once each year, if in the opinion of the mortgagee of the
Building or Landlord's insurance agent the amount of such insurance coverage at
that time is not adequate. Notwithstanding the fact that any liability of Tenant
to Landlord may be covered by Tenant's insurance, Tenant's liability shall in no
way be limited by the amount of its insurance recovery.

(c) Property Insurance. Throughout the Lease Term, Tenant shall maintain
all-risk property insurance on the value of all tenant improvements to the
Demised Premises (whether constructed by Landlord or Tenant), the value of all
Alterations and the value of Tenant's personal property located within the
Demised Premises.

(d) Tenant Construction. During the course of construction of any tenant
improvements or Alterations by Tenant in the Demises Premises, until completion
thereof, Tenant shall hire only commercial contractors licensed and insured in
the State of Maryland and shall obtain a certificate of insurance showing
liability coverage of at least Two Million Dollars ($2,000,000.00) which names
Tenant, Landlord and Guardian Realty Management, Inc., as additional insureds.

(e) Workers' Compensation Insurance. Throughout the Lease Term, Tenant
shall maintain workers' compensation insurance as required by law.

(f) Business Interruption Insurance. Throughout the Lease Term, Tenant
shall maintain business interruption insurance with limits to cover a period of
not less than twelve (12) months loss of income, including extra expense
coverage with a period of restoration of one hundred eighty (180) days.

(g) Policy Requirements. All insurance required under this Lease shall be
issued by insurance companies authorized to do business in the jurisdiction
where the Building is located. Such companies shall have a policyholder rating
of at least "A" and be assigned a financial size category of at least "Class
XIV" as rated in most recent edition of "Best's Key Rating Guide" for insurance
companies. All such insurance shall contain only reasonable deductibles. Tenant
shall request (in writing) that its insurance carrier provide Landlord with 30
days' written notice before cancellation or any material change in the coverage,
scope or amount of any policy. Tenant shall promptly notify Landlord in writing
in the event Tenant receives any such notice from its insurance company. Each
policy, or a certificate showing it is in effect, together with evidence of
payment of premiums, shall be deposited with Landlord at the commencement of the
Lease Term, and renewal certificates or copies of renewal policies shall be
delivered to Landlord at least thirty (30) days prior to the expiration date of
any policy.

(h) Landlord Insurance. Throughout the Lease Term, Landlord shall maintain
such insurance in such amounts as is customary for a Landlord to maintain on
property of similar size and nature of the Building.

(i) Waiver of Subrogation. Landlord and Tenant mutually covenant and agree
that each party, in connection with insurance policies required to be furnished
in accordance with the terms of this Lease, or in connection with insurance
policies which they obtain insuring such insurable interest as Landlord or
Tenant may have in its own properties, whether personal or real, shall expressly
waive any right of subrogation on the part of the insurer against the Landlord
(and Landlord's Rental Agent and any mortgagee requested by Landlord) or Tenant
as the same may be applicable, which right to the extent not prohibited or
violative of any such policy is hereby expressly waived, and Landlord and Tenant
each mutually waive all right of recovery against each other, their agents, or
employees for any loss, damage or injury of any nature whatsoever to property
for which either party carries, or is required by this Lease to carry,
insurance.

20. DAMAGE BY CASUALTY.

(a) Fire or Casualty Damage. If the Demised Premises shall be damaged by
fire or other casualty, then, except as otherwise provided in subparagraphs (b)
and (c) hereof, Landlord, at Landlord's expense, shall promptly restore the
Demised Premises, and Tenant, at Tenant's sole expense, shall promptly restore
all leasehold improvements installed in the Demised Premises (by Landlord or
Tenant) and its own furniture, furnishings, trade fixtures and equipment. No
penalty shall accrue for reasonable delay which may arise by reason of
adjustment of insurance on the part of Landlord, or on account of labor
problems, or any other cause beyond Landlord's reasonable control. If the damage
or destruction is such as to make the Demised Premises or any substantial part
thereof untenantable (in Landlord's judgment), and provided that such damage or
destruction is not due in whole or part to the act or omission of Tenant or
Tenant's agents, employees or invitees, the Base Annual Rent shall abate
proportionately (based on proportion of the number of square feet rendered
untenantable to the total number of square feet of the Demised Premises), from
the date of the damage or destruction until the date the Demised Premises has
been restored by Landlord. Except as

hereinabove set forth, no compensation, or claim, or diminution of rent will be
allowed or paid by Landlord, by reason of inconvenience, annoyance, or injury to
business, arising from the necessity of repairing the Demised Premises or any
portion of the Building of which they are a part.

(b) Substantial Damage. If the Demised Premises are substantially damaged
or are rendered substantially untenantable by fire or other casualty, or if
Landlord's architect certifies that the Demised Premises cannot be repaired
within ninety (90) business days of normal working hours, said period commencing
with the start of the repair work, or if Landlord shall decide not to restore or
repair the same, or if more than fifty percent (50%) of the GLA of the Building
is rendered untenantable (even if the Demised Premises is undamaged) or if
Landlord shall decide to demolish the Building or not to rebuild it, then
Landlord may, within ninety (90) days after such fire or other casualty,
terminate this Lease by giving Tenant a notice in writing of such decision, and
thereupon the term of this Lease shall expire by lapse of time upon the third
day after such notice is given, and Tenant shall vacate the Demised Premises and
surrender the same to Landlord. Upon the termination of this Lease under the
conditions hereinabove provided, Tenant's liability for Base Annual Rent and
Additional Rent shall cease as of the day following the casualty.

(c) Insurance Proceeds. The proceeds payable under all casualty insurance
policies maintained by Landlord on the Demised Premises shall belong to and be
the property of Landlord, and Tenant shall not have any interest in such
proceeds. Tenant agrees to look to Tenant's casualty insurance policies for the
restoration and replacement of all of the improvements installed in the Demised
Premises (by Landlord or Tenant) and Tenant's fixtures, equipment and
furnishings in the Demised Premises, and in the event of termination of this
Lease, for any reason, following any such damage or destruction, Tenant shall
promptly assign to Landlord or otherwise pay to Landlord, upon Landlord's
request, all proceeds of said insurance except those proceeds payable with
respect to Tenant's trade fixtures and equipment. Notwithstanding anything to
the contrary in this Section 20 or in any other provision of this Lease, any
obligation (under this Lease or otherwise) of Landlord to restore all or any
portion of the Demised Premises shall be subject to Landlord's receipt of
approval of the same by the mortgagee(s) of Landlord (and any approvals required
by applicable laws), as well as receipt from any such mortgagee(s) of such fire
and other hazard insurance policy proceeds as may have been assigned to any such
mortgagee, it being agreed that if Landlord has not received such approval(s)
and proceeds within ninety (90) days after any such casualty, then Landlord
shall have the right to terminate this Lease, at any time thereafter, upon
notice to Tenant, in which case the rent shall be apportioned and paid to the
date of said fire or other casualty.

21. CONDEMNATION.

In the event the whole or a substantial part of the Demised Premises or the
Building shall be taken for any public or quasi-public purpose by any lawful
power or authority by exercise of the right of appropriation, condemnation or
eminent domain, or sold to said authority to prevent such taking (collectively
referred to herein as a "taking"), Landlord shall have the right to terminate
this Lease effective as of the date possession is required to be surrendered to
said authority, and rent shall be apportioned as of that date. For purposes of
this Section, a substantial part of the Demised Premises or the Building shall
be considered to have been taken if, in Landlord's sole opinion, the taking
shall render it commercially undesirable for Landlord to permit this Lease to
continue or to continue operating the Building. Tenant shall not assert any
claim against Landlord or the taking authority for any compensation arising out
of or related to such taking and Landlord shall be entitled to receive the
entire amount of any award without deduction for any estate or interest of
Tenant; provided, however, that nothing contained in this Section shall be
deemed to prevent Tenant from filing a claim with the taking authority for an
award for the taking of personal property and fixtures belonging to Tenant and
relocation expenses, as long as such award is made in addition to and separately
stated from any award made to Landlord for the Demised Premises and the Building
and does not reduce the amount of Landlord's award. If Landlord does not elect
to terminate this Lease, the Base Annual Rent and Additional Rent payable by
Tenant pursuant to Section 4 shall be adjusted (based on the ratio that the
number of square feet of rentable area taken from the Demised Premises bears to
the number of rentable square feet in the Demised Premises immediately prior to
such taking) as of the date possession is required to be surrendered to said
authority. Landlord shall have no obligation to contest any taking.

22. BANKRUPTCY.

(a) Events of Bankruptcy. Any one or more of the following shall be deemed
an "Event of Bankruptcy" under this Lease: (1) Tenant's or any guarantor of
Tenant's obligations under this Lease ("Tenant's Guarantor") becoming insolvent,
as that term is defined in Title 11 of the United States Code (the "Bankruptcy
Code"), or under the insolvency laws of any state, district, commonwealth or
territory of the United States (the "Insolvency Laws"); (2) the appointment of a
receiver or custodian for any or all of Tenant's or Tenant's Guarantor's
property or assets, or the institution of a foreclosure action upon any of
Tenant's or Tenant's Guarantor's real or personal property; (3) the filing of a
voluntary petition under the provisions of the Bankruptcy Code or Insolvency
Laws; (4) the filing of an involuntary petition against Tenant or Tenant's
Guarantor as the subject debtor under the Bankruptcy Code or Insolvency Laws,
which either (A) is not dismissed within thirty (30) days of filing, or (B)
results in the issuance of an order for relief against the debtor; or (5)
Tenant's or Tenant's Guarantor's making or consenting to an assignment for the
benefit of creditors or a common law composition of creditors.

(b) Termination of Lease. Upon the occurrence of an Event of Bankruptcy, or
if Tenant takes advantage of any Insolvency Laws, then in any such event
Landlord at its option and sole discretion may terminate this Lease by written
notice to Tenant (subject, however, to applicable provisions of the Bankruptcy
Code or Insolvency Laws during the pendency of any action thereunder involving
Tenant as the subject debtor). If this Lease is terminated under this Section
22, Tenant shall immediately surrender and vacate the Demised Premises, waives
all statutory or other notice to quit, and agrees that Landlord's obligations
under this Lease shall cease from such termination date, and Landlord may
recover possession by process of law or in any other lawful manner. Furthermore,
if this Lease terminates under this Section 22(b), Landlord shall have all
rights and remedies against Tenant provided in case of default of Tenant in the
payment of Base Annual Rent and/or Additional Rent.

(c) Assumption by Trustee. If Tenant becomes the subject debtor in a case
pending under the Bankruptcy Code, Landlord's right to terminate this Lease
under this Section 22 shall be subject to the applicable rights (if any) of the
Trustee in Bankruptcy to assume or assign this Lease as then provided for in the
Bankruptcy Code. However, the Trustee in Bankruptcy must give to Landlord and
Landlord must receive proper written notice of the Trustee's assumption or
rejection of this Lease within sixty (60) days (or such other applicable period
as is provided for in the Bankruptcy Code) after the date of the Trustee's
appointment, it being agreed that failure of the Trustee to give notice of such
assumption hereof within said period shall conclusively and irrevocably
constitute the Trustee's rejection of this Lease and waiver of any rights of the
Trustee to assume or assign this Lease. The Trustee shall not have the right to
assume or assign this Lease unless said Trustee (i) promptly and fully cures all
defaults under this Lease, (ii) promptly and fully compensates Landlord for all
monetary damages incurred as a result of such default, and (iii) provides to
Landlord adequate assurance of future performance (as defined herein below). For
purposes of this paragraph, the term "promptly" shall mean within a period not
more than sixty (60) days from the date of assumption of this Lease.

(d) Liquidated Damages. It is further stipulated and agreed that, in the
event of the termination of this Lease by the happening of any event described
in this Section 22, Landlord shall forthwith, upon such termination, and any
other provisions of this Lease to the contrary notwithstanding, become entitled
to recover, as liquidated damages for such breach of the provisions of this
Lease, an amount equal to the difference between the then cash value of the Base
Annual Rent reserved hereunder for the unexpired portion of the Lease Term
demised, and the then cash rental value of the Demised Premises for such
unexpired portion of the Lease Term hereby demised, unless the statute which
governs or shall govern the proceedings in which such damages are to be proved
limits or shall limit the amount of such claim capable of so being proved, in
which case Landlord shall be entitled to prove as liquidated damages an amount
equal to that allowed by or under any such statute. The provisions of this
Section 22(d) shall be without prejudice to (i) Landlord's right to prove in
full damages for Base Annual Rent and Additional Rent accrued prior to the
termination of this Lease, but not paid, or (ii) any rights given to Landlord by
any pertinent statute to prove any amounts allowed thereby. In making any such
computation, the rental value of the Demised Premises shall be deemed prima
facie to be the base rental realized upon any reletting, if such reletting can
be accomplished by Landlord within a reasonable time after such termination of
this

Lease, and the then cash value of any future rent shall be computed by
discounting at a rate equal to one (1) whole percentage point above the discount
rate then in effect at the Federal Reserve Bank with jurisdiction over banks in
the area in which the Building is located.

23. DEFAULTS AND REMEDIES.

(a) Default. Each of the following shall be deemed a Default by Tenant and
a breach of this Lease:

(i) A failure by Tenant to pay Base Annual Rent or Additional Rent
herein reserved by the fifth (5th) business day of each month during the Lease
Term; provided that Tenant shall have five (5) days after written notice from
Landlord within which to cure any such monetary default, such cure right only to
be provided twice in any twelve (12) month period; or

(ii) An assignment or encumbrance of Tenant's interest in this Lease
or the Demised Premises or a subletting of the Demised Premises in violation of
Section 9;

(iii) A failure by Tenant in the observance or performance of any
other term, covenant, agreement or condition of this Lease on the part of Tenant
to be observed or performed, including the Rules and Regulations, after ten (10)
days written notice; provided that if the default cannot be cured within such
ten (10) day period, then Tenant shall have a longer period not to exceed thirty
(30) days within which to cure such default so long as Tenant has commenced the
cure within the initial ten (10) day period and is diligently proceeding to
correct any such failure;

(iv) An Event of Bankruptcy as defined in Section 22;

(v) Tenant's abandonment of the Demised Premises;

(vi) Any material misrepresentation by Tenant to Landlord in
connection with the negotiation and/or execution of this Lease; or

(vii) A default by Tenant beyond any applicable cure period under any
other lease for space in the Building.

(b) Remedies. Upon Default by Tenant of any of the terms or covenants of
this Lease, Landlord shall be entitled to remedy such default as follows:

(i) Termination and Re-entry. Landlord shall have the right, at its
sole option, to terminate this Lease. In addition, with or without terminating
this Lease, Landlord may re-enter, terminate Tenant's right of possession and
take possession of the Demised Premises by such proceedings as may be
applicable. The provisions of this section shall operate as a notice to quit,
any other notice to quit or of Landlord's intention to re-enter the Demised
Premises being expressly waived. If Landlord elects to terminate this Lease
and/or elects to terminate Tenant's right of possession, then all of Landlord's
obligations as set forth in this Lease shall cease. Landlord may relet the
Demised Premises or any part thereof, alone or together with other premises, for
such term(s) (which may extend beyond the date on which the Lease Term would
have expired but for Tenant's default) and on such terms and conditions (which
may include concessions or free rent and alterations of the Demised Premises) as
Landlord, in its sole discretion, may reasonably determine, but Landlord shall
not be liable for, nor shall Tenant's obligations be diminished by reason of,
Landlord's failure to relet the Demised Premises or collect any rent due upon
such reletting. Whether or not this Lease is terminated, Tenant nevertheless
shall remain liable for the Base Annual Rent, Additional Rent and any other sums
or damages which may be due or sustained prior to the later of termination of
this Lease or Landlord's recovery of possession of the Demised Premises, and all
costs, fees and expenses (including without limitation reasonable attorneys'
fees in the event of any dispute regarding the Lease, brokerage fees and
expenses incurred in placing the Demised Premises in a rentable condition
substantially similar to the condition in which Landlord delivered the Demised
Premises to Tenant) incurred by Landlord in pursuit of its remedies and in
renting the Demised Premises to others from time to time. Tenant shall also be
liable for additional damages which at Landlord's election shall be either
Monthly Damages or Present Value Damages. "Monthly Damages" shall be an amount
equal to the Base Annual Rent and Additional Rent which would have become due
during the remainder of the Lease Term, less the amount of rental, if any, which

Landlord receives during such period from others to whom the Demised Premises
may be rented (other than any additional rent payable as a result of any failure
of such other person to perform any of it obligations), which damages shall be
computed and payable in monthly installments, in advance, on the first day of
each calendar month following Tenant's default and continuing until the date on
which the Lease Term would have expired but for Tenant's default. Separate suits
may be brought to collect any such Monthly Damages for any month(s), and such
suits shall not in any manner prejudice Landlord's right to collect any such
damages for any subsequent month(s), or Landlord may defer any such suit until
after the expiration of the Lease Term, in which event such suit shall be deemed
not to have accrued until the expiration of the Lease Term. "Present Value
Damages" shall be an amount equal to the present value (as of the date of
Tenant's default) of the Base Annual Rent and Additional Rent which would have
become due through the date on which the Lease Term would have expired but for
Tenant's default, which damages shall be payable to Landlord in a lump sum on
demand. For purpose of this section, present value shall be computed by
discounting at a rate equal to one (1) whole percentage point above the discount
rate then in effect at the Federal Reserve Bank with jurisdiction over banks in
the area in which the Building is located. Tenant waives any right of
redemption, re-entry or restoration of the operation of this Lease under any
present of future law, including any such right which Tenant would otherwise
have if Tenant shall be dispossessed for any cause.

(ii) Reduction of Tenant's Rights. Landlord shall have the right to
terminate any renewal or expansion right contained in this Lease, and to grant
or withhold any consent or approval pursuant to this Lease in its sole and
absolute discretion, if an Event of Default has occurred that has not been
remedied by Tenant in a timely manner as provided hereunder. If this Lease
requires Landlord to be reasonable in giving any prior written consent or
approval of an action by Tenant, Landlord nevertheless shall not be required to
be reasonable in approving the action of Tenant if Tenant took the action
without first seeking Landlord's prior written consent pursuant to this Lease.
Landlord shall have no obligation to refund to Tenant or to credit to Tenant
against any other amounts or installments coming due to Landlord hereunder any
amount otherwise owed or creditable by Landlord to Tenant pursuant to the terms
of this Lease if (i) Tenant is in default hereunder but an Event of Default has
not occurred, unless such default is cured prior to the expiration of any
applicable grace period or (ii) an Event of Default has occurred. The provisions
of this subsection shall apply notwithstanding anything to the contrary in this
Lease, and whether or not this Lease and/or Tenant's right of possession is
terminated as a result of Tenant's default.

(iii) Right of Landlord to Cure Tenant's Default. If Tenant fails to
make any payment to any third party or to do any act required to be made or done
by Tenant, then Landlord may, but shall not be required to, make such payment or
do such act. The amount of any resulting expense or cost to Landlord, including
attorneys' fees, with interest thereon at the rate of eighteen percent (18%) per
annum or the highest legal rate, whichever is lower, accruing from the date paid
by Landlord, shall be paid by Tenant to Landlord and shall constitute Additional
Rent hereunder, due and payable by Tenant upon receipt of a written statement
detailing such costs from Landlord. The making of such payment or the doing of
such act by Landlord shall not operate to cure Tenant's default, nor shall it
prevent Landlord from the pursuit of any remedy to which Landlord would
otherwise be entitled.

(iv) Lien for Rent. Upon any default by Tenant in the payment of Base
Annual Rent or Additional Rent, Landlord shall have a lien upon the property of
Tenant in the Demised Premises for the amount of any unpaid Base Annual Rent or
Additional Rent. In such event, Tenant shall not remove any of Tenant's property
from the Demised Premises except with the prior written consent of Landlord.
Notwithstanding the above, if Tenant has vacated or is no longer operating its
business in the Demised Premises, Landlord shall have the right and privilege,
at its option, to take possession of all property of Tenant in the Demised
Premises, to store the same on the Demised Premises, or to remove it and store
it in such place as may be selected by Landlord, at Tenant's risk and expense.

(c) Landlord's Remedies Cumulative. All rights and remedies of Landlord
herein enumerated shall be cumulative and in addition to Landlord's other rights
and remedies at law or in equity, including those available as a result of any
anticipatory breach of this Lease. Landlord's exercise of any such right or
remedy shall not prevent the concurrent or subsequent exercise of any other
right or remedy. For the purposes of any suit brought or based hereon, this
Lease shall be construed to be a divisible contract, to the end that successive
actions may be maintained on this Lease as successive periodic sums mature
hereunder.

(d) Non-Waiver. No payment by Tenant or receipt by Landlord of lesser
amounts of rent than those herein stipulated shall be deemed to be other than on
account of the earliest unpaid stipulated rent. No endorsement or statement on
any check or any letter accompanying any check or payment as rent shall be
deemed an accord and satisfaction, and Landlord may accept such check or payment
without prejudice to Landlord's right to recover the balance of such rent or
pursue any other remedy provided in this Lease. Notwithstanding any request or
designation by Tenant, Landlord may apply any payment received from Tenant to
any payment then due. Re-entry and acceptance of keys shall not be considered an
acceptance of surrender. No waiver of any breach of any covenant, condition or
agreement herein contained on one or more occasions shall operate as a waiver of
the covenant, condition or agreement itself, or of any subsequent breach
thereof. Landlord's delay or failure to exercise or enforce any of Landlord's
rights or remedies or Tenant's obligations shall not constitute a waiver of any
such rights, remedies or obligations. No provision of this Lease shall be deemed
to have been waived by Landlord unless such waiver shall be in writing signed by
Landlord.

24. LENDER REQUIREMENTS.

(a) Subordination. Tenant agrees that this Lease is subject and subordinate
to all ground or underlying leases and to all mortgages or deeds of trust which
may now or hereafter be made a lien on the Building, and to all renewals,
modifications, consolidations, replacements and extensions thereof. This
subordination provision shall be self-operative and no further instrument of
subordination shall be required. Tenant agrees to execute and deliver, upon
request, such further instrument or instruments confirming this subordination
(and its agreement to attorn described in Section 24(b)) as shall be reasonably
desired by Landlord, or by any ground lessor or any mortgagee or proposed
mortgagee; and, in the event Tenant does not execute and deliver to Landlord
such an instrument within ten (10) days of receipt of Landlord's request
therefor, Tenant hereby constitutes and appoints Landlord as Tenant's
attorney-in-fact solely to execute any such instrument or instruments. Tenant
shall be liable for any loss incurred by Landlord resulting from Tenant's
failure to timely execute and deliver any instrument requested by Landlord
confirming such subordination, and shall reimburse Landlord for the amount of
any such loss upon demand, as Additional Rent. Tenant further agrees that, at
the option of the holder of any mortgage or of the trustee under any deed of
trust, this Lease may be made superior to said mortgage or first deed of trust.

(b) Attornment. In the event any proceedings are brought for the
foreclosure of, or in the event of exercise of the power of sale under, any deed
to secure debt given by Landlord and covering the Demised Premises, Tenant shall
attorn to the purchaser upon any such foreclosure or sale and recognize such
purchaser as the owner and landlord under this Lease, provided such owner, as
landlord, shall recognize Tenant's rights to continue to occupy the Demised
Premises and exercise all of its rights hereunder so long as Tenant complies
with the terms and provisions of this Lease. Tenant further covenants and agrees
to attorn to any successor to Landlord's interest in any ground or underlying
lease, and in that event, this Lease shall continue as a direct lease between
Tenant herein and such landlord or its successor.

(c) New Financing. In the event that the trust or mortgage lender providing
the first mortgage interim construction financing for the Building and/or the
first mortgage permanent financing for the Building requires, as a condition of
such financing, that modifications to this Lease be obtained, and provided that
such modifications (i) are reasonable, (ii) do not adversely affect Tenant's use
of the Demised Premises as herein permitted, (iii) do not materially alter the
approved Space Plan for the Demised Premises, (iv) do not increase the rent and
other sums required to be paid by Tenant hereunder, and (v) do not otherwise
increase Tenant's rights and obligations hereunder, then Landlord may submit to
Tenant a written amendment to this Lease incorporating such required
modifications, and, in the event Tenant does not execute and return to Landlord
such written amendment within ten (10) business days after the same has been
submitted to Tenant, then Landlord shall thereafter have the right, at its sole
option, to cancel this Lease. Such option shall be exercisable by Landlord
giving Tenant written notice of cancellation, immediately whereupon this Lease
shall be canceled and terminated, and any money or security therefor deposited
by Tenant with Landlord shall be returned to Tenant, subject to the provisions
of Section 5 of this Lease, and both Landlord and Tenant shall thereupon be
relieved from any and all further liability or obligation hereunder.

(d) Financial Statements. Tenant agrees, from time to time but not more
often than once per calendar year, upon not less than fifteen (15) days prior
written notice by Landlord, to

deliver to Landlord such financial statements as Landlord may request. Financial
statements are defined as the published financial statements for up to the last
completed quarter already published. If Tenant shall fail to provide Landlord
with Tenant's financial statements within fifteen (15) days after receipt of
Landlord's written request therefor, Landlord may impose a penalty in the amount
of the lesser of (i) One Hundred Dollars ($100.00) per day for each day after
such date that Tenant's failure to provide such financial statements continues,
or (ii) Three Thousand Dollars ($3,000.00). Any such penalty shall be payable by
Tenant, as Additional Rent, within ten (10) days after Landlord's written demand
therefor.

25. ESTOPPEL CERTIFICATES.

Tenant agrees, at any time and from time to time, upon not less than seven
(7) business days prior written notice by Landlord, to execute, acknowledge and
deliver to Landlord a written estoppel certificate (i) certifying that this
Lease is unmodified and in full force and effect (or if there have been
modifications, stating the nature of same), (ii) stating the Commencement Date
of the Lease Term, (iii) stating the amounts of Base Annual Rent and Additional
Rent and the dates to which the Base Annual Rent and Additional Rent have been
paid by Tenant, (iv) stating the amount of any Security Deposit, (v) stating
whether or not to the best knowledge of Tenant, Landlord is in default in the
performance of any covenant, agreement or condition contained in this Lease,
and, if so, specifying each such default of which Tenant may have knowledge,
(vi) stating that Tenant has no right to setoff and no defense against payment
of the Base Annual Rent or Additional Rent, (vii) stating the address to which
notices to Tenant should be sent, and (viii) certifying such other matters as
may be requested by Landlord. Any such certificate delivered pursuant hereto may
be relied upon by an owner of the Building, any prospective purchaser of the
Building, any mortgagee or prospective mortgagee of the Building or of
Landlord's interest therein, or any prospective assignee of any such mortgage.
Failure to deliver the aforesaid certificate within the seven (7) business days
shall be conclusive upon Tenant for the benefit of Landlord and any successor to
Landlord that this Lease is in full force and effect and has not been modified
except as may be represented by the party requesting the certificate, and by
such failure Tenant shall be deemed to have irrevocably constituted and
appointed Landlord as its attorney-in-fact coupled with an interest to execute
and deliver the aforesaid certificate to the aforesaid parties, in its name,
place and stead. Tenant shall be liable for any loss incurred by Landlord
resulting from Tenant's failure to timely execute and deliver any estoppel
certificate requested by Landlord, and shall reimburse Landlord for the amount
of any such loss upon demand, as Additional Rent.

26. TENANT HOLDOVER.

(a) With Landlord Consent. If Tenant continues, with the knowledge and
written consent of Landlord obtained at least thirty (30) days prior to the
expiration of the Lease Term, to remain in the Demised Premises after the
expiration of the Lease Term, and in that event, Tenant shall, by virtue of this
agreement become a tenant by the month at Base Monthly Rent which is one and
one-half (1.5) times the Base Monthly Rent applicable to the last month of the
Lease Term, and otherwise subject to the terms, covenants and conditions herein
specified, commencing said monthly tenancy with the first day next after the end
of the Lease Term.

(b) Without Landlord Consent. In the event that Tenant, without the consent
of Landlord, shall hold over the expiration of the term hereby created, then
Tenant shall become a tenant of sufferance only, at a monthly rent which is
three (3) times the Base Monthly Rent applicable to the last month of the Lease
Term, and otherwise subject to the terms, covenants and conditions herein
specified. Tenant expressly agrees to hold Landlord harmless from all loss and
damages, direct and consequential, which Landlord may suffer in defense of
claims by other parties against Landlord arising out of the holding over by
Tenant, including without limitation attorney's fees which may be incurred by
Landlord in defense of such claims. Acceptance of rent by Landlord subsequent to
the expiration of the Lease Term shall not constitute consent to any holding
over. Landlord shall have the right to apply all payment received after the
expiration date of this Lease toward payment for use and occupancy of the
Demised Premises subsequent to the expiration of the Lease Term and toward any
other sums owed by Tenant to Landlord. Landlord, at its option, may forthwith
re-enter and take possession of the Demised Premises without process, or by any
legal process in force.

27. RELOCATION. INTENTIONALLY DELETED.

28. QUIET ENJOYMENT.

So long as Tenant shall observe and perform all the covenants and
agreements binding on it hereunder Tenant shall at all times during the term
herein granted, peacefully and quietly have and enjoy possession of the Demised
Premises without any encumbrance or hindrance by, from or through Landlord,
except as provided for elsewhere under this Lease.

29. LIMITATION OF LANDLORD'S LIABILITY.

It is understood and agreed that the liability of the Landlord hereunder
shall be limited solely to its interest in the Building of which the Demised
Premises form a part; and that neither Landlord nor (if Landlord is a
partnership) any partner of Landlord nor (if Landlord is a corporation) any
shareholder of Landlord nor (if Landlord is a limited liability company) any
member of Landlord shall be personally liable with respect to any claim arising
out of or related to this Lease.

30. TIME OF THE ESSENCE.

Landlord and Tenant acknowledge that time is of the essence in the
performance of any and all of their respective obligations, terms, and
provisions of this Lease.

31. WAIVER OF JURY TRIAL.

Landlord and Tenant each hereby waive any right to a jury trial with
respect to this Lease and/or any matters arising hereunder.

32. NOTICES.

(a) Addresses for Notices. All notices required or desired to be given
hereunder by either party to the other shall be given in person, by certified or
registered mail, return receipt requested, or by Airborne Express, United Parcel
Service, Federal Express or any other widely used overnight delivery service,
and addressed as specified in Section 1(a). Either party may, by like written
notice, designate a new address to which such notices shall be directed.

(b) Effective Date of Notice. Notice shall be deemed to be effective upon
delivery (or at such time delivery is refused) when delivered in person, by
certified or registered mail, return receipt requested, or Airborne Express,
United Parcel Service, Federal Express or any other widely used overnight
delivery service, or by facsimile.

33. POSTPONEMENT OF PERFORMANCE.

In the event that either party hereto shall be delayed or hindered in or
prevented from the performance of any act required hereunder by reason of
strikes, labor troubles, inability to procure labor or materials, failure of
power, restrictive governmental laws or regulations, riots, insurrection, war,
acts of God, fire or other casualty or other reason of a similar or dissimilar
nature beyond the reasonable control of the party delayed in performing work or
doing acts required under the terms of this Lease, then performance of such act
shall be excused for the period of the delay and the period for the performance
of any such act shall be extended by a period equivalent to the period of such
delay. The provisions of this paragraph shall not operate to excuse Tenant from
the prompt payment of Base Annual Rent or Additional Rent and shall not operate
to extend the Lease Term. Delays or failures to perform resulting from lack of
funds shall not be deemed delays beyond the reasonable control of a party.

34. BROKERS.

Landlord and Tenant each represents and warrants to the other that it has
not employed any broker in connection with this Lease transaction, except the
broker named in Section 1(a)(25). Said broker shall be paid a brokerage
commission pursuant to a separate agreement between Landlord and said broker,
and Landlord and Tenant each shall indemnify and hold harmless the other from
and against any claims for brokerage or other commission arising by reason of a
breach by the indemnifying party of the aforesaid representation and warranty.

35. MISCELLANEOUS PROVISIONS.

(a) Governing Law. The laws of the state in which the Building is located
shall govern the validity, performance and enforcement of this Lease.

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

(c) No Representations by Landlord. Neither Landlord nor any agent of
Landlord has made any representations or promises with respect to the Demised
Premises or the Building except as herein expressly set forth, and no rights,
privileges, easements or licenses are granted to Tenant except as herein
expressly set forth.

(d) Exhibits. It is agreed and understood that any Exhibits referred to
herein and attached hereto form an integral part of this Lease and are hereby
incorporated by reference.

(e) Pronouns. Feminine or neuter pronouns shall be substituted for those of
the masculine form, and the plural shall be substituted for the singular number,
in any place or places herein in which the content may require such substitution
or substitutions. Landlord and Tenant herein for convenience have been referred
to in neuter form.

(f) Captions. All section and paragraph captions herein are for the
convenience of the parties only, and neither limit nor amplify the provisions of
this Lease.

(g) Landlord's Approval. Whenever Landlord's consent or approval is
required under the terms of this Lease, Landlord may grant or deny such consent
or approval in its sole discretion unless otherwise specified herein. Tenant
hereby waives any right to damages based upon Landlord's actually or allegedly
wrongfully withholding or delaying any consent or approval under or in
connection with this Lease. Tenant's sole remedy for any wrongfully withheld or
delayed consent or approval shall be a proceeding for specific performance, or
injunction or declaratory judgment.

(h) Invalidity of Particular Provisions. If any term or provision of this
Lease or applications thereof to any person or circumstance shall, to any
extent, be invalid or unenforceable, the remaining terms and provisions of this
Lease, 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 Lease shall be valid and
enforced to the fullest extent permitted by law.

(i) Covenants. The parties hereto agree that all the provisions of this
Lease are to be construed as covenants and agreements as though the words
importing such covenants and agreements were used in each separate provision
hereof.

(j) Interpretation. Although the printed provisions of this Lease were
drawn by Landlord, this Lease shall not be construed for or against Landlord or
Tenant, but this Lease shall be interpreted in accordance with the general tenor
of the language in an effort to reach the intended result. The deletion of any
printed, typed or other portion of this Lease, or any earlier draft of this
Lease, shall not evidence an intention to contradict such deleted portion. Such
deleted portion shall be deemed never to have been inserted in this Lease.

(k) Joint and Several Liability. If more than one natural person and/or
entity shall constitute Tenant or if Tenant is a general partnership or other
entity, the partners or members of which are subject to personal liability, then
the liability of each such person, entity, partner or member shall be joint and
several.

(1) Counterparts. This Lease has been executed in several counterparts, but
all counterparts shall constitute one and the same legal document.

(m) Recordation. Tenant shall not record among any public records this
Lease and/or its Exhibits or any short form of this Lease without Landlord's
prior written consent, which may be granted or withheld in Landlord's sole
discretion. Notwithstanding the above, Landlord

acknowledges and agrees that Tenant shall, if required by the rules of NASDAQ
stock exchange, record this Lease and/or its Exhibits or any short form of this
Lease.

contain all the agreements and conditions made between the parties and may not
be modified orally or in any other manner than by an agreement in writing,
signed by the parties hereto.

(o) Authority. Landlord and Tenant hereby covenant each for itself, that
each has full right, power and authority to enter into this Lease upon the terms
and conditions herein set forth. If Tenant signs as a corporation, each of the
persons executing this Lease on behalf of Tenant does hereby covenant and
warrant that Tenant is a duly authorized and existing corporation, qualified to
do business in the jurisdiction in which the Demised Premises is located, that
the corporation has full right and authority to enter into this Lease, and that
each and both of the persons signing on behalf of the corporation were
authorized to do so. If Tenant signs as a partnership or limited liability
company, each of the persons executing this Lease on behalf of Tenant does
hereby covenant and warrant that Tenant is a duly formed and validly existing
partnership or limited liability company, as the case may be, that the
partnership or limited liability company has full right and authority to enter
into this Lease, and that each of the persons signing on behalf of the
partnership or limited liability company were authorized to do so.

(p) Examination of Lease. Submission of this Lease for examination or
signature by Tenant shall not constitute reservation of or option for Lease, and
the same shall not be effective as a Lease or otherwise until execution and
delivery by both Landlord and Tenant.

(q) Rule Against Perpetuities. If any interest created by this Lease has
failed to vest within twenty (20) years from the date of execution hereof, this
Lease shall immediately terminate twenty (20) years from the date first set
forth hereinabove.

(r) Confidentiality. Tenant agrees to keep confidential all terms of this
Lease, as well as any and all discussions and/or negotiations with Landlord
prior to and related to this Lease.
