                                 Tenant to Landlord hereunder.

     2. Demised Premises and Term. (a) Landlord hereby leases to Tenant, and
Tenant hereby leases from Landlord, subject to the terms, covenants and
conditions of this Lease, the Demised Premises in the Building for the Term set
forth in Section 1 hereof, unless such right is sooner terminated as provided
herein, commencing on the Commencement Date and ending on the Expiration Date.
The Demised Premises are outlined on the floor plan attached hereto and made a
part hereof as Exhibit "A". The sole purpose of the attached floor plan is to
identify the general location of the Demised Premises in the Building and such
floor plan is not a representation as to the actual size of the Premises.

     (b) The "Commencement Date" shall be the earlier of the date set forth in
Section 1 hereof or the date that Tenant first uses the Demised Premises or any
portion thereof for any purpose permitted under this Lease. Notwithstanding the
foregoing, in the event this Lease involves interior finish improvements to be
constructed in the Demised Premises by Landlord ("Landlord's Work"), the
"Commencement Date" shall be the later of the foregoing date or the date upon
which Landlord's Work shall have been substantially completed, provided however,
that if Landlord shall be delayed in such substantial completion as a result of:
(i) Tenant's request for materials, finishes or installations other than
Landlord's building standard; (ii) Tenant's changes to the Space Plan described
in Exhibit "D" after lease execution by Tenant; or (iv) any other

                                       2

<PAGE>

act, omission or delay by Tenant; the Commencement Date shall be accelerated by
the number of days of such delay, and provided further that if Landlord cannot
substantially complete the Demised Premises as a result of any events (i)
through (iv) above, Landlord may as its election complete so much of Landlord's
Work as may be practical under the circumstances and, by written notice to
Tenant, establish the Commencement Date as the date of such partial completion,
subject to any applicable accelerations due to delays resulting from events (i)
through (iv) above. Taking possession by Tenant shall be deemed conclusively to
establish that the Demised Premises have been completed in accordance with the
Space Plan described in Exhibit "D" and that the Demised Premises are in good
and satisfactory condition, as of when possession was so taken. Tenant
acknowledges that no representations as to the repair of the Demised Premises
have been made by Landlord, unless such are expressly set forth in this Lease.
After such "Commencement Date" Tenant shall, upon demand, execute and deliver to
Landlord a letter of acceptance of delivery of the Demised Premises. In the
event of any dispute as to substantial completion of Landlord's Work, the
certificate of Landlord's a third party architect or contractor shall be
conclusive. If Landlord shall be unable to give possession of the Demised
Premises on the Commencement Date because the Demised Premises are not ready for
occupancy or if Landlord's Work is not completed, or for any other reason,
Landlord shall not be subject to any liability for failure to give possession on
said date, nor shall such failure affect the continuing validity of this Lease
or be deemed to affect the Term of the Lease, but in such event Tenant shall not
be liable for any Rent until such time as Landlord tenders delivery of
possession of the Demised Premises to Tenant ready for occupancy. The Demised
Premises shall not be deemed to be unready for Tenant's occupancy or incomplete
if only minor or insubstantial details of construction, decoration or mechanical
adjustments remain to be done in the Demised Premises or any part thereof.


     (c) In connection with Landlord's Work, where compliance is required by the
Americans with Disabilities Act ("ADA"), Landlord shall comply with the ADA in
all respects where said compliance is readily achievable. To the best of
Landlord's knowledge, all aspects of the interior finish work to be performed as
Landlord's work shall comply with ADA specifications. After the Commencement
Date, and subject to the foregoing, where said compliance is readily achievable,
Landlord shall comply with ADA in the common areas of the Building as such
compliance relates to the general operation of the Building and Tenant shall be
responsible for ADA compliance both within the Premises and within the Building
to the extent compliance relates to Tenant's use of the Demised Premises or use
of the Demised Premises by Tenant's employees, agents or invitees. Both Landlord
and Tenant shall be given ample and appropriate opportunity to challenge any ADA
compliance order or notice received from the applicable governmental authority.

     3. Payment of Rent. All Annual Base Rent and Additional Rent payable by
Tenant pursuant to the terms of this Lease shall be paid to Landlord, without
notice or demand and without deduction, abatement or set off of any kind, c/o
Savitar Realty Advisors as Managing Agent for the Landlord, 2301 W. Sample Road,
Building 3, Suite 5A, Pompano Beach, Florida 33073 or by Electronic Funds
Transfer to Landlord's banking institution or to such other person, firm or
corporation as Landlord may, from time to time, designate in writing. The
covenant of payment of Rent is an independent covenant of Tenant in this Lease.
If the Term commences on a date other than the first day of a calendar month, or
ends on a date other than the last day of a calendar month, then the Rent
(including all Annual Base Rent payable pursuant to Section 4 hereof and all
Additional Rent payable pursuant to Section 5 hereof) for such partial calendar
month shall be prorated on the basis of the actual number of days in such month
included within the Term hereof.

     4. Annual Base Rent. Tenant shall pay to Landlord, throughout the Term of
this Lease the Annual Base Rent set forth in Subsection 1(m) as follows:


          (a) Annual Base Rent shall be payable in twelve (12) equal monthly
     installments of the Monthly Base Rent set forth in Subsection 1(n) with
     each monthly installment to be due and payable in advance on or before the
     first day of each and every month during the Term of this Lease, except
     that Monthly Base Rent for the first four full calendar month for which
     Monthly Base Rent shall be due, shall be paid when Tenant executes this
     Lease ("Prepaid Rent").

          (a)  Definition of Operating Expenses.

               (1) For purposes of this Section 5, the term "Operating Expenses"
          shall mean and include all expenses, costs, fees and disbursements
          paid or incurred by or on behalf of the Landlord of every kind and
          nature for owning, managing, operating, maintaining, restoring and
          repairing the Development and the personal property used in
          conjunction therewith, including (without limitation) the cost of
          electricity, steam, water, sewer, gas, fuel, heating, lighting, air
          conditioning, window cleaning, janitorial services, insurance,
          including but not limited to, fire, extended coverage, liability,
          workmen's compensation, elevator, or any other insurance carried by
          the Landlord and applicable to the Development, painting, uniforms,
          management fees, supplies, sundries, sales or use taxes on supplies or
          services, cost of wages and salaries of all persons engaged in the
          operation, administration, maintenance and repair of the Development,
          and fringe benefits, including social security taxes, unemployment
          insurance taxes, cost for providing coverage for disability benefits,
          cost of any pensions, hospitalization, welfare or retirement plans, or
          any other similar or like expenses incurred under the provisions of
          any collective bargaining agreement, or any other cost or expense
          which Landlord pays or incurs to provide benefits for employees so
          engaged in the operation, administration, maintenance and repair of
          the Development, the charges of any independent contractor who, under
          contract with the Landlord or its representatives, does any of the
          work of operating, maintaining or repairing of the Development, legal
          and accounting expenses, any expenses allocated to the Development
          under any reciprocal easement or other agreements relating to any
          common facilities and services appurtenant to the Development, or any
          other expense or charge, whether or not hereinbefore mentioned, which
          in accordance with generally accepted accounting or management
          principles would be considered as an expense of owning, managing,
          operating, maintaining or repairing the Development. In order to avoid
          or reduce the impact of artificial distortions in any given year,
          certain Operating Expenses may be amortized by Landlord over a period
          of several years or Landlord may make equitable adjustments where an
          item of Operating Expenses is not representative of what is typical
          for a particular calendar year. The term Operating Expenses shall not
          include costs or other items included within the meaning of the term
          "Taxes" (as hereinafter defined), costs of alterations of the premises
          of tenants of the Development, costs of capital improvements to the
          Development, depreciation charges, interest and principal payments on
          mortgages, ground rental payments, and real estate brokerage and
          leasing commissions, except as hereinafter otherwise provided.

               (2) Notwithstanding anything contained in this Subsection 5(a) to
          the contrary, the cost of any capital improvements to the Development
          or alterations of the premises of tenants of the Development, or to
          the HVAC systems thereof, made after the date of this Lease which are
          intended to reduce Operating Expenses, or designed to protect the
          health and safety of the tenants in the Development, or which are
          required under any governmental laws, regulations, or ordinances which
          were not applicable to the Development at the time it was constructed,
          amortized over such reasonable period as Landlord shall determine,
          together with interest on the unamortized cost of any such improvement
          (at the corporate base interest rate at the First National Bank of
          Chicago on the date the cost of such improvement was incurred) shall
          be included in the definition of Operating Expenses.

               (3) If the aggregate space of the Development is less than
          ninety-five percent (95%) occupied by tenants during all or a portion
          of any calendar year, then Landlord shall make an appropriate

                                       5
<PAGE>

          adjustment for such year of those components of Operating Expenses
          which may vary depending upon the occupancy level of the Development
          so that all of such variable components of Operating Expenses paid or
          incurred by Landlord and included in Operating Expenses for such year,
          are ratably allocated to the tenants then occupying space in the
          Development. Any such adjustments shall also be deemed expenses paid
          or incurred by Landlord and included in Operating Expenses for such
          year, as if the Development had been fully occupied and the Landlord
          had paid or incurred such expenses. If Landlord does not furnish
          during any calendar year any particular work or service to tenant who
          has undertaken to perform such work or service in lieu of the
          performance thereof by Landlord, (the cost of which, if performed by
          Landlord, would constitute an Operating Expense) Operating Expenses
          shall be deemed to be increased by an amount equal to the additional
          expense which would reasonably have been incurred during such calendar
          year by Landlord if it had, at its own expense, furnished such work or
          service to such Tenant.

               (4) Attached hereto as Exhibit "E" are Operating Expense
          Exclusions as clarified and agreed to by Tenant and Landlord.

          (b) Definition of Taxes.

               (1) For purposes of this Section 5, the term "Taxes" shall mean
          real estate taxes, assessments and any other federal, state or local
          governmental charge, general, special, ordinary or extraordinary (but
          not including general income or franchise taxes or any other taxes
          imposed upon or measured by income or profits, unless the same shall
          be imposed in lieu of Taxes as herein defined or unless same shall be
          specifically imposed upon income derived from rents), which may now or
          hereafter be levied or assessed against the Development, any
          renovation, rehabilitation or improvement thereof, or any portion of
          the Development for any "Tax Year" (as herein define ) during the
          Term. In case of special taxes or assessments which may be payable in
          installments, only the amount of each installment paid during a Tax
          Year shall be included in Taxes for such Tax Year. Except as provided
          in the preceding sentence, all references to Taxes "for" a particular
          Tax Year shall be deemed to refer to Taxes levied, assessed or
          otherwise imposed for such Tax Year without regard to when such Taxes
          are payable. Taxes shall also include any personal property taxes
          (attributable to the Tax Year in which paid) imposed upon the
          furniture, fixtures, machinery, equipment, apparatus, systems and
          appurtenances used in connection with the operation of the
          Development. Taxes also include the Landlord's reasonable costs and
          expenses (including reasonable attorney's fees) in contesting or
          attempting to reduce any Taxes. Notwithstanding anything contained in
          this Subsection 5(b) to the contrary, if at any time the method of
          taxation then prevailing shall be altered so that any new or
          additional tax, assessment, levy, imposition or charge or any part
          thereof shall be imposed upon Landlord in place or partly in place of
          any such Taxes, or contemplated increase therein or in addition to any
          such Taxes, and shall be measured by or be based in whole or in part
          upon the real property or the rents or other income therefrom, then
          all such new taxes, assessments, levies, impositions or charges or
          part thereof, to the extent that they are so measured or based, shall
          be included in Taxes levied, imposed or assessed against the real
          property to the extent that such items would be payable if the real
          property were the only property of Landlord subject thereto and the
          income received by Landlord from the real property were the only
          income of Landlord. The term "Tax Year" as used in this Subsection
          5(b) means a twelve (12) month period established by Landlord as the

                                       6
<PAGE>

          year for purposes of computing the aggregate of Taxes due and payable
          under this Lease.

               (2) In the event the Development is not assessed as fully
          improved or occupied for any Tax Year, then Taxes shall be adjusted to
          the Taxes which would have been payable in such Tax Year if the
          assessment has been made on a fully improved or occupied basis, based
          on Landlord's adjustment of the "Taxes" for such Tax Year, employing
          sound management principles.

          (c)  Definition of Tenant's Proportionate Share.

               (1) For purposes of this Section 5 and for purposes of the Lease
          in general, the term Tenant's proportionate Share represents a
          percentage obtained by dividing the Rentable Area in the Demised
          Premises by the Rentable Area of the Development, as determined by
          Landlord.

               (2) The term "Rentable Area of the Development" as used in this
          Lease shall mean the sum of the areas on all floors of the three (3)
          buildings in the Development computed by measuring the inside face of
          the exterior glass or finished column or exterior wall of the
          buildings on each entire floor, plus mechanical space, common service
          areas available for use by all tenants in the buildings, reception and
          lobby areas, vending machine and commissary areas and loading docks
          and excluding only public stairs, elevator shafts, flues, stacks, pipe
          shafts and vertical ducts measured from the outside wall surface of
          such spaces ("vertical penetrations"). No deduction shall be made for
          columns or projections necessary to the buildings.

               (3) The term "Rentable Area of the Demised Premises" as used in
          this Lease shall mean (A) if this Lease is for an entire floor, the
          area of the entire floor measured to the inside finished surface of
          the exterior glass or finished column or exterior wall of the building
          in which the Demised Premises are located, excluding vertical
          penetrations, plus a proportionate share of the building's mechanical
          space and common service areas; or (B) if this Lease is for less than
          an entire floor, the area measured from the inside finished surface of
          the exterior glass or finished column or exterior wall of the building
          in which the Demised Premises are located to the center line of all
          demising partitions and to the inside finished surface of the office
          side of corridor and other permanent walls, plus (I) a proportionate
          share of public areas (including corridors, elevator lobbies, toilets,
          mechanical spaces and janitor, electrical and telephone closet(s) on
          the floor housing the Demised Premises; and (III) a proportionate
          share of mechanical space and common service areas in the building in
          which the Demised Premises are located. In making the calculations
          pursuant to (A) or (B) above, no deduction shall be made for columns
          or projections necessary to the building in which the Demised Premises
          are located.

          (d) Calculation of Additional Rent. In addition to the Annual Base
     Rent, the Tenant shall pay as "Additional Rent", the "Operating Expense
     Rent Adjustments" and "Tax Rent Adjustments" (as hereinafter defined and
     collectively referred to as "Rent Adjustments") without set-off or
     deduction to the Landlord in the manner hereinafter set forth. The amount
     of Rent Adjustments due and payable under this Lease shall be calculated as
     follows:

               (1) In the event that the amount of "Operating Expenses" (as
          herein defined) attributable to and for any calendar year shall be
          greater than the "Operating Expense Base" [as defined in Subsection
          1(p)], then the Tenant shall pay to the Landlord as Additional Rent

                                      7
<PAGE>

         "Tenant's Proportionate Share" (as herein defined) of such excess
          (said amount being the "Operating Expense Rent Adjustment"); and

               (2) In the event that the amount of "Taxes" (as herein defined)
          attributable to and for any Tax Year shall be greater than the "Tax
          Base" [as defined in Subsection 1(o)], then the Tenant shall pay to
          Landlord, as Additional Rent, the Tenant's Proportionate Share of such
          excess (said amount being the "Tax Rent Adjustment").

          (e) Monthly Payments of Tax Rent Adjustments. As soon as reasonably
     feasible after the expiration of each Tax Year and after the Taxes for such
     Tax Year are determined, Landlord shall furnish to Tenant a statement ("Tax
     Adjustment Statement") showing the following: (i) Taxes for such Tax Year;
     (ii) the Tax Rent Adjustment due Landlord for such Tax Year, less credits
     for Rent Adjustment Deposits for Taxes, if any, paid for such Tax Year; and
     (iii) the "Rent Adjustment Deposit" (as herein defined) for Taxes due for
     the current Tax Year. The term "Rent Adjustment Deposit" means an amount
     equal to Landlord's estimate of Rent Adjustments due for any Tax Year.
     Within thirty (30) days after Tenant's receipt of each Tax Adjustment
     Statement, Tenant shall pay Landlord: (1) the Tax Rent Adjustments shown on
     said Statement to be due Landlord for the Tax Year last ended, plus (2) the
     lump sum amount, which when added to the Rent Adjustment Deposits for Taxes
     theretofore paid in the current Tax Year, if any, would provide the
     Landlord with an amount that Landlord would have theretofore been paid had
     Tenant paid one-twelfth of the Rent Adjustment Deposit for Taxes shown on
     said Statement, for the current Tax Year, to Landlord monthly on the first
     day of each month of such Tax Year. Commencing on the first day of the
     first month after Tenant's receipt of such Tax Adjustment Statement, and on
     the first day of each month thereafter until Tenant receives a more current
     Tax Adjustment Statement, Tenant shall pay to Landlord one-twelfth of the
     Rent Adjustment Deposit for Taxes shown on said Statement. During the last
     complete Tax Year, Landlord may include in the Rent Adjustment Deposit for
     Taxes its estimate of the Tax Rent Adjustment which may not be finally
     determined until after the expiration of the Term. The Tenant's obligation
     to pay the Tax Rent Adjustment shall survive the Term. Notwithstanding
     anything in this Subsection (e) to the contrary, Landlord may, at any time,
     during the first Tax Year deliver to Tenant, a statement ("First Year Tax
     Deposit Statement") setting forth the Rent Adjustment Deposit for Taxes due
     for such Tax Year. If Landlord delivers such Statement, Tenant shall pay
     Rent Adjustment Deposits for Taxes for such first Tax Year in the same
     manner as though said Rent Adjustment Deposit.

          (f) Monthly Payments of Operating Expense Rent Adjustments. As soon as
     reasonably feasible after the expiration of each calendar year, Landlord
     will furnish Tenant a statement ("Operating Expense Adjustment Statement")
     showing the following: (i) Operating Expenses attributable to the calendar
     year last ended; (ii) the Operating Expense Rent Adjustments due Landlord
     for the calendar year last ended, less credits for Rent Adjustment Deposits
     for Operating Expenses paid, if any paid for such calendar year; and (iii)
     the Rent Adjustment Deposit for Operating Expenses due for the current
     calendar year. Within thirty (30) days after Tenant's receipt of each
     Operating Expense Adjustment Statement, Tenant shall pay to Landlord: (1)
     the Operating Expense Rent Adjustments shown on said Statement to be due
     Landlord for the calendar year last ended; plus (2) the lump sum amount,
     which when added to the Rent Adjustment Deposit for Operating Expenses
     theretofore paid in the current calendar year, if any, would provide the
     Landlord with an amount that Landlord would have theretofore been paid had
     Tenant paid one-twelfth (1/12) of the Rent Adjustment Deposit for Operating

                                       8
<PAGE>

     Expenses shown on said Statement, for the current calendar year, to
     Landlord monthly on the first day of each month of such calendar year.
     Commencing on the first day of the first month after Tenant's receipt of
     each Operating Expense Adjustment Statement, and on the first day of each
     month thereafter until Tenant receives a more current Operating Expense
     Adjustment Statement, Tenant shall pay to Landlord one-twelfth (1/12) of
     the Rent Adjustment Deposit for Operating Expenses shown on said Statement.
     During the last complete calendar year, Landlord may include in the Rent
     Adjustment Deposit for Expenses its estimate of the Operating Expense Rent
     Adjustment which may not be finally determined until after the expiration
     of the Term. The Tenant's obligation to pay the Operating Expense Rent
     Adjustment shall survive the Term. Notwithstanding anything in this
     Subsection (f) to the contrary, Landlord may, at any time, during the first
     calendar year deliver to Tenant, a statement ("First Year Operating Expense
     Deposit Statement") setting forth the Rent Adjustment Deposit for Operating
     Expenses due for such calendar year. If Landlord delivers such Statement,
     Tenant shall pay Rent Adjustment Deposits for Operating Expenses for such
     first calendar year in the same manner as though said Rent Adjustment
     Deposits for Operating Expenses had been set forth in an Operating Expense
     Adjustment Statement delivered to Tenant.

          (g) Annual Payments of Rent Adjustments. Tenant's payment of the Rent
     Adjustment Deposits for each calendar year, or Tax Year as the case may be,
     shall be credited against the applicable Rent Adjustments for such calendar
     year or Tax Year. All Rent Adjustment Deposits need not be kept separate
     and apart and no interest shall be paid to Tenant thereon. If the Rent
     Adjustment Deposit paid by Tenant for any calendar year, or Tax year as the
     case my be, exceeds the applicable Rent Adjustments for such calendar year,
     or Tax Year as the case may be, then Landlord shall give a credit to Tenant
     in an amount equal to such excess against the applicable Rent Adjustments
     due for the next succeeding calendar year, except that if any such excess
     relates to the last calendar year, or Tax Year as the case may be, of the
     Term, then Landlord shall refund such excess to Tenant, provided that all
     of the following have first occurred:

               (1)  the Term has expired or otherwise been terminated;

               (2) Tenant has vacated the Demised Premises and removed all of
          its property and improvements therefrom in accordance with this Lease;

               (3) Tenant has surrendered the Demised Premises to Landlord in
          accordance with this Lease; and

               (4) Tenant has paid all Annual Base Rent and Rent Adjustments due
          under this Lease and has fully performed and observed each and every
          term, covenant and condition of this Lease required to be performed or
          observed by Tenant.

          (h) Special Allocations. Landlord and Tenant acknowledge that certain
     costs of the Development are allocated among the several buildings in the
     Development using methods of allocation that are considered reasonable and
     appropriate under the circumstances. Tenant hereby consents to such
     allocations provided that the determination of such costs and the
     allocation of all or part thereof to Operating Expenses and Taxes hereunder
     shall be in accordance with generally accepted accounting principles
     applied on a consistent basis.

         (i) Audit. Provided an Event of Default on the part of the Tenant is
     not then existing, Tenant or its accountant (but not a subtenant) shall
     have the right after seven (7) days prior written notice to Landlord to
     examine Landlord's books and records of Operating Expenses and Taxes for
     the immediately preceding calendar year during normal business hours at the
     office of Landlord or Landlord's agent within sixty days (60) days
     following the furnishing of the Tax and Operating Expense Adjustment
     Statements to Tenant. Unless Tenant takes written exception to any item
     within sixty days (60) days following the furnishing of the Adjustment
     Statements to Tenant (which item shall be paid in any event), such
     statements shall be considered as final and accepted by Tenant. Tenant may
     take exception to matters included in Taxes or Operating Expenses, or
     Landlord's computation of Tenant's Proportionate Share of either, by
     sending notice specifying such exception and the reasons


                                       9
<PAGE>

     therefor to Landlord no later than thirty (30) days after Landlord makes
     such records available for examination. Such Rent Adjustment Statements
     shall be considered final, except as to matters to which exception is taken
     after examination of Landlord's records in the foregoing manner and within
     the foregoing times. Tenant acknowledges that Landlord's ability to budget
     and incur expenses depends on the finality of such Statement, and
     accordingly agrees that time is of the essence of this Subsection. If
     Tenant takes exception to any matter contained in the Rent Adjustment
     Statements as provided herein, Landlord shall refer the matter to an
     independent certified public accountant, whose certification as to the
     proper amount shall be final and conclusive as between Landlord and Tenant.
     Tenant shall promptly pay the cost of such certification unless such
     certification determines that Tenant was overbilled by more than two
     percent (2%). Pending resolution of any such exceptions in the foregoing
     manner, Tenant shall continue paying Tenant's Proportionate Share of Taxes
     and Operating Expenses in the amounts determined by Landlord, subject to
     adjustment after any such exceptions are so resolved. Tenant acknowledges
     that Landlord has made no representation, warranty or guaranty relating to
     the amount of the Tax Base and Operating Expense Base.

     6. Permitted Use. Tenant shall use and occupy the Demised Premises
continuously for the permitted use set forth in Subsection 1(s) only, and for no
other purpose unless agreed to in writing by Landlord. Tenant shall at its own
cost and expense obtain any and all licenses and permits necessary for its use
of the Demised Premises. Tenant's use shall not violate any recorded covenants,
conditions and restrictions affecting the Development or any law or the
certificate of occupancy issued for the Building of which the Demised Premises
is a part, and Tenant shall, upon five (5) days written notice from Landlord,
discontinue any use of the Demised Premises which is declared to be a violation
of any recorded covenants, conditions and restrictions affecting the Development
or of any law or of said certificate of occupancy. Tenant shall comply with any
directive of any governmental authority which shall impose any duty upon Tenant
or Landlord with respect to the Demised Premises or with respect to the use or
occupancy thereof. Tenant shall upon demand immediately reimburse Landlord as
additional rent for any costs incurred by Landlord as a result of Tenant's
failure to comply with the provisions of this Section 5. Tenant shall not do or
permit to be done anything in or about the Demised Premises which will in any
way obstruct or interfere with the rights of other tenants or occupants of the
Development, or use or allow the Demised Premises to be used for any unlawful or
objectionable purpose. Tenant shall not permit any action which would constitute
a nuisance or would disturb or endanger any other tenants of Development or
unreasonably interfere with such tenants' use of their respective premises or
permit any use which would adversely affect the reputation of the Development.
Tenant will not use or permit the Demised Premises or any part there of to be
used for any disorderly, unlawful or hazardous purpose.

     7. Governmental Compliance. Tenant shall, at its own expense, comply (and
Tenant shall not permit a failure in compliance of the Demised Premises) with
all laws, orders, ordinances and regulations of federal, state, county and
municipal authorities, which are currently and may hereafter be in force and
effect, and with directions of public officers thereunder, and notices from
Landlord's mortgagee and any ground lessor, respecting all matters of use,
occupancy, alteration, condition or maintenance of the Demised Premises, whether
such orders or directions shall be directed to Tenant or Landlord, and Tenant
shall hold Landlord harmless from any cost or expenses on account thereof.

     8. Surrender of Demised Premises at Lease Expiration. Tenant agrees to keep
the Demised Premise and the fixtures therein clean and in good order and repair
and will, at the expiration or earlier termination of the Term hereof, surrender
and deliver up the same in broom clean and in like good order and repair, as the
same now is or shall be at the Commencement Date, ordinary wear and tear
excepted and loss by casualty covered by insurance to be secured pursuant to
Section 20 excepted (but not excepting any damage or loss not reimbursed by
insurance because of the existence of a deductible under the appropriate
policy), failing which Landlord may restore the same at Tenant's sole cost and
expense at one hundred fifteen percent (115%) of Landlord's cost therefor.
Tenant shall give written notice to Landlord at least thirty (30) days prior to
vacating the Demised Premises and shall arrange to meet with Landlord for a
joint inspection of the Demised Premises prior to vacating. In the event of
Tenant's failure to give such notice or arrange such joint inspection,
Landlord's inspection at or after Tenant's vacating the Demised Premises shall
be conclusively deemed correct for purposes of determining Tenant's
responsibility for repairs and restoration. The vacation of the Building or move
into the Building by Tenant, shall be governed by such reasonable rules and
regulations adopted by Landlord from time to time, provided such rules and
regulations are uniformly applied to all tenants.

                                       10

     9. Assignment and Subletting. (a) Tenant shall not transfer, assign,
mortgage or encumber this Lease by operation of law or otherwise, or sublet or
permit the Demised Premises, or any part thereof to be used by others, including
concessionaires or licensees of Tenant, without the prior written consent of
Landlord in each instance, and Tenant shall not permit a use other than the use
specified in Section 5. Any attempted transfer, assignment, subletting,
mortgaging or encumbering of this Lease in violation of the foregoing sentence
shall be null and void and confer no rights upon any third person. No permitted
assignment or subletting shall relieve Tenant from any of its obligations under
this Lease. If Landlord consents to any such transfer, assignment or subletting,
the same shall not be effective unless and until (i) Tenant gives written notice
thereof to Landlord; and (ii) such transferee, assignee or sublessee shall
deliver to Landlord (A) a written agreement in form and substance satisfactory
to Landlord pursuant to which such transferee, assignee or sublessee assumes all
of the obligations and liabilities of Lease hereunder, and (B) a certified copy
of the document or agreement memorializing such transaction.

          (b) If, without prior written consent, this Lease is transferred or
     assigned by Tenant, or if the Demised Premises, or any part thereof, are
     subject or occupied by anybody other than Tenant, whether as a result of
     any act or omission by Tenant, or by operation of law or otherwise,
     Landlord, whether before or after the occurrence of an event of default,
     may, in addition to, and not in diminuation of or substitution for, any
     other rights and remedies under this Lease or pursuant to law to which
     Landlord may be entitled as a result thereof, collect Rent from the
     transferee, assignee, subtenant or occupant and apply the net amount
     collected to the Rent herein reserved, but no such transfer, assignment,
     subletting, occupancy or collection shall be deemed a waiver of the
     provisions of this or the acceptance of the transferee, assignee,
     subtenant, or occupant as Tenant, or a release of Tenant from the further
     performance by Tenant of its obligation under this Lease.

          (c) Neither the consent by Landlord to any transfer, assignment or
     subletting nor the reference in any provision of this Lease or in any rules
     and regulations to concessionaires and licensees shall in anywise be
     construed to relieve Tenant from obtaining, in each instance, the express
     consent in writing of Landlord to any further transfer, assignment or
     subletting or to the granting of any concession or license for the use of
     any part of the Demised Premises.

          (d) Landlord shall not unreasonably withhold its consent described in
     the foregoing provisions provided, should Landlord withhold its consent for
     one of the following reasons, which list is not exclusive, such withholding
     shall be deemed to be reasonable: (i) Landlord has not received for
     approval at least thirty (30) days before the proposed transaction a copy
     of a fully executed unconditional assignment or sublease in a form
     acceptable to Landlord together with detailed information as to the
     character, reputation, business experience and financial statement of the
     third party; (ii) in the reasonable judgement of Landlord the proposed
     sublessee or assignee is of a character or reputation or engaged in a
     business which is not in keeping with the standards of Landlord for the
     Building; (iii) in the reasonable judgment of Landlord the purpose for
     which the proposed sublessee or assignee intends to use the Demised Premise
     are not in keeping, unsuitable or incompatible with the standards of
     Landlord for the Building, or are in violation of the terms of any other
     leases in the Building, it being understood that the purpose for which the
     proposed sublessee or assignee intends to use the Demised Premise may not
     be in violation of this Lease; (iv) a subletting will result in there being
     more than two occupants within the Demised Premises, including Tenant and
     all sublessees; (v) the Demised Premises is not regular in shape with the
     appropriate means of ingress and egress and suitable for normal renting
     purposes; (vi) the proposed sublessee or assignee is either a government
     (or subdivision agency thereof) or an occupant or an affiliate of an
     occupant of the Building; (vii) an assignment is desired and the Demised
     Premises are less than the entire Demised Premises or less than the
     remaining lease term is being assigned; (viii) the assignee or sublessee is
     not, in the judgement of Landlord, sufficiently financially responsible or
     stable to perform its obligations under the proposed sublease or
     assignment; (ix) Tenant is in default under this Lease; or (x) the
     transaction with the assignee or sublessee will cause Landlord to incur
     excessive costs or expenses relative to compliance under governmental laws.

                                       11

     The foregoing are merely examples of reasons for which Landlord may
     reasonably withhold its consent and shall not be deemed exclusive of any
     permitted reasons for withholding consent, whether similar or dissimilar to
     the foregoing examples.

          (e) If Tenant is or becomes a closely-held corporation and if during
     the Term of this Lease, the ownership of the shares of stock which
     constitute control of Tenant changes other than by reason of gift or death,
     Tenant shall notify Landlord of such change within five (5) days thereof.
     Landlord, at its option, may at any time after such change terminate this
     Lease by giving Tenant reasonable written notice of said termination. The
     term "control" as used herein means the power to directly or indirectly
     direct or cause the direction of the management or policies of the Tenant.
     A change or series of changes in ownership of stock which would result in
     direct or indirect change in ownership by the stockholders or an affiliated
     group of stockholders of less than fifty percent (50%) of the outstanding
     stock as of the date of the execution and delivery of this Lease shall not
     be considered a change of control.

          (f) If Tenant is an entity, whether it be a partnership, corporation,
     trust, limited liability company, or any other type of entity, the Tenant
     must get the written consent of Landlord before Tenant can convert to be a
     different type of entity.

          (g) If Tenant is an entity whose ownership is not publicly held, and
     if during the Term, the ownership of the control of Tenant changes, Tenant
     shall notify Landlord of such change within five (5) days thereof, and
     Landlord, at its option, may at any time thereafter terminate this Lease by
     giving Tenant written notice of said termination at lease sixty (60) days
     prior to the date of termination stated in the notice. The term "control"
     as used herein means the power to directly or indirectly direct or cause
     the direction of the management or policies of the Tenant. A change or
     series of changes in ownership of stock which would result in direct or
     indirect change in ownership by the stockholders or an affiliated group of
     stockholders of less than fifty percent (50%) of the outstanding stock
     shall not be considered a change of control.

     10. Insurance. (a) Tenant shall procure and maintain in full force and
effect at Tenant's own expense commencing on the date Tenant first uses any part
of the Premises or the Premises are first made available to Tenant and during
the entire Term the types and amounts of insurance specified below, upon terms
and conditions satisfactory to Landlord, with insurance companies authorized to
do business in the state in which the property is located, and having an A.M.
Best's rating of A:X or better from the Bests' Key Rating Guide, insuring Tenant
and, as "Additional Insureds", Landlord and Landlord's beneficiaries and their
shareholders, partners, agents and employees, and where required by Landlord,
the mortgagee or ground lessor against claims, damages or losses which may arise
out of, in connection with or result form Tenant's use and occupancy of the
Premises, which insurance policies shall be on an occurrence basis:


          (i) Commercial general liability insurance, including but not limited
     to Premises/Operations, Personal Injury, Contractual Liability, Independent
     Contractors, Broad Form Property Damage, and Products/Completed Operations
     coverages, with limits of not less than $2,000,000 per occurrence combined
     single limit bodily injury, personal injury, and property damage. The
     Additional Insureds are to be named on a primary, non-contributory basis.


          (ii) Commercial Automobile Liability insurance on an Occurrence basis,
     covering all owned, non-owned and hired automobiles, including the loading
     and unloading thereof, with limits not less than $1,000,000 per occurrence
     combined single limit bodily injury and property damage. If there are no
     owned automobiles, non-owned and hired coverage may be included within the
     Commercial General Liability insurance policy. The Additional Insureds
     shall be named on a primary, non-contributory basis.

          (iii) Property Insurance on All Risks of Loss basis, including but not
     limited to the perils of fire, extended coverage, vandalism and malicious
     mischief, flood, and sewer backup, and business interruption, insuring on a

                                       12
<PAGE>

     replacement cost basis, and on a no coinsurance basis, Tenant's furniture,
     trade fixtures, equipment, merchandise, improvements and alterations, and
     any other items of Tenant's property on the Premises. Such policy shall
     include a waiver of subrogation in favor of the Additional Insureds.

          (v) Worker's Compensation and Occupational Disease insurance in
     accordance with the statutes of the state in which the property is located
     or any other applicable jurisdiction and Employer's Liability insurance
     with limits not less than $500,000 per accident or illness, covering all
     employees of Tenant. Such policy shall include a waiver of Subrogation in
     favor of the Additional Insureds.

          (b) Tenant shall comply with all applicable laws and ordinances, all
     orders and decrees of court and all requirements of other governmental
     authorities, and shall not directly or indirectly make any use of the
     premises which may thereby be prohibited or be dangerous to person or
     property or which may jeopardize any insurance coverage, or may increase
     the cost of insurance or require additional insurance coverage.

          (c) The foregoing insurance may be provided by a company wide blanket
     insurance policy or policies maintained by or on behalf of Tenant, provided
     that such policy(s) references the Premises as insured and the Additional
     Insureds, as required by this Lease as additional insureds parties, sets a
     minimum guaranteed coverage amount for the Premises, and is otherwise
     reasonably satisfactory to Landlord. No policy for Tenant's insurance shall
     provide for a deductible amount which exceeds $1,000.00. Each insurance
     policy shall provide for thirty (30) days prior written notice to Landlord
     or any material change, cancellation, or non-renewal, and shall contain a
     clause setting forth that such policy shall be primary with respect to any
     policies maintained by Landlord or the other Additional Insureds and that
     any coverage carried by Landlord shall be excess insurance. The amount of
     any insurance company's liability under the policies specified herein shall
     not be reduced by the existence of such other insurance. Each insurer shall
     waive its rights of subrogation against the Additional Insureds.

          (d) Evidence of insurance coverage and limits required above shall in
     no way limit Tenant's liabilities and responsibilities under the Lease. Any
     and all deductibles applicable to the required coverages shall be borne
     solely by Tenant.

          (e) Tenant shall, prior to the Commencement Date of the Term, furnish
     to Landlord certificates of insurance on insurance on Standard Accord forms
     evidencing such required coverages to be in force on the Commencement Date,
     and during the Term shall furnish renewal certificates thirty (30) days
     prior to the expiration of any of the policies of insurance. Such
     certificates shall state that: a) Landlord and its beneficiaries and their
     shareholders, partners, agents and employees, and the mortgagee or ground
     lessor are Additional Insureds on a primary, non-contributory basis; b)
     Insurer will provide thirty (30) days prior notice of cancellation,
     non-renewal, or material change to Landlord; and, c) Insurer waives its
     rights of subrogation against the Additional Insureds to the extent
     required above.

          (f) Landlord maintains the right to reasonably modify, delete, alter,
     or change these requirements.

          (g) Tenant shall not do or permit to be done any act or thing upon the
     Demised Premises that will invalidate or be in conflict with fire insurance
     policies covering the building or any part thereof, or fixtures and
     property Paragraph, and shall comply with all rules, orders, regulations or
     requirements of the Board of Fire Underwriters having jurisdiction, or any

                                       13
<PAGE>

     other similar body, in the case of such fire insurance policies, and the
     applicable insurance rating bureau or similar body in the case of all other
     such insurance policies, and shall not do, or permit anything to be done,
     in or upon the Demised Premises, or bring or keep anything therein, which
     shall increase the rate office insurance on the building or on any property
     located therein, or increase the rate or rates of any other insurance
     referred to hereinabove. If, by reason of the failure of Tenant to comply
     with the provisions of this subsection, the fire insurance rate, or the
     rate or rates of any other insurance coverage referred to in this Section,
     shall at any time be higher than it otherwise would be, and if Landlord, at
     such time, is obligated to obtain and maintain in effect any such insurance
     coverage, then Tenant shall reimburse Landlord on demand, as additional
     rent, for that part of all premiums for any insurance coverage that shall
     have been charged because of such violation by Tenant and which Landlord
     shall have paid on account of an increase in the rate or rates in its own
     policies of insurance. In any action or proceeding wherein Landlord and
     Tenant are parties, a schedule or "makeup" or rates for the Development or
     Demised Premises issued by the Fire Insurance Exchange having jurisdiction,
     or other body establishing rates in the case of all of the other aforesaid
     insurance policies, shall be conclusive evidence of the facts therein
     stated and of the several items and charges in the fire insurance rate and
     other insurance rates then applicable to the Demised Premises.

          (h) Tenant agrees to indemnify and hold harmless, and at the option of
     Landlord defend at Tenant's sole cost (with counsel acceptable to
     Landlord), Landlord and Landlord's agents, employees and mortgagees and
     their respective officers, directors, shareholders and partners (all of
     such parties are for purposes of this Section 10 referred to herein as
     "Indemnitees") from and against any and all claims, losses, fines, suits,
     judgments, orders, decrees, actions, proceedings, damages, injuries,
     penalties, escalations of insurance cost, liabilities, demands, costs, and
     expenses, including reasonable attorney's and consultants' fees for the
     defense thereof or incurred in connection therewith, whether known or
     unknown, anticipated or unanticipated, that (i) will arise from or are in
     connection with the possession, use, occupation, repair, maintenance or
     control of the Demised Premises, or any portion thereof; or (ii) arise from
     or are in connection with any act or omission of Tenant or Tenant's agents,
     employees, contractors, licensees, subtenants, assignees, or invitees; or
     (iii) result from any default, breach, violation or nonperformance of this
     Lease or any provision herein on the part of Tenant to be performed
     pursuant to the terms of this Lease; or (iv) result in injury or death to
     persons or damage to or loss of property or business sustained in or about
     the Demised Premises. Tenant shall pay, satisfy and discharge any and all
     judgments, orders and decrees which may be recovered against Landlord in
     connection with the foregoing. If Landlord exercises its option to have
     Tenant's counsel defend Landlord, Tenant's counsel shall not enter into a
     settlement of any matter without the prior express written consent of
     Landlord.

          (i) Landlord and Tenant agree to have all fire and extended coverage
     and material damage insurance which may be carried by either of them
     endorsed with a clause providing that any release from liability of or
     waiver of claim for recovery from the other party entered into in writing
     by the insured thereunder prior to any loss or damage shall not affect the
     validity of said policy or the right of the insured to recover thereunder
     and providing further that the insurer waives all rights of subrogation
     which such insurer might have against the other party. Without limiting any
     release or waiver of liability or recovery contained in any other Section
     of the Lease but rather in confirmation and furtherance thereof, each of
     the parties hereto waive all claims for recovery from the other party for
     any loss or damage to any of its property insured under valid and
     collectible insurance policies to the extent of any recovery collectible
     under such insurance policies. Notwithstanding the foregoing or anything
     contained in this Lease to the contrary, any release or any waiver of
     claims shall not be operative, nor shall the foregoing endorsements be
     required, in any case where the effect of such release or waiver is to
     invalidate insurance coverage or the right of the insured to recover
     thereunder or increase the cost thereof (provided that in the case of
     increased cost the other party shall have the right, within ten [10] days
     following written notice, to pay such increased cost keeping such release
     or waiver in full force and effect).

                                       14
<PAGE>

          (j) It is expressly understood and agreed that nothing in this Lease
     shall be construed as creating any liability against Landlord, its partners
     or agents or their successors and assigns, personally, and in particular
     without limiting the generality of the foregoing, there shall be no
     personal liability to pay any indebtedness accruing hereunder or to perform
     any covenant, either express or implied, herein contained, and that all
     personal liability of Landlord, its partners or agents or their successors
     and assigns, of every sort, if any, is hereby expressly waived by Tenant,
     and that so far as Landlord, its partners or agents or their successors and
     assigns is concerned Tenant shall look solely to the equity in the
     Development and the rents, issues and profits therefrom for the
     satisfaction of the remedies of the Tenant in the event of a breach by the
     Landlord. It is mutually agreed that this clause is and shall be considered
     an integral part of the Lease. Such exculpation of personal liability is
     absolute and without any exception whatsoever.

     11. Alterations. (a) Tenant will not make any alterations, installations,
changes, replacements, additions, or improvements, structural or otherwise,
("Alterations") in or to the Demised Premises or any part thereof, without the
review of the plans by and the prior written consent of Landlord therefor. In
addition, the Tenant shall make written request of Landlord to notify Tenant in
writing of any pre-existing conditions in the areas in which Tenant desires to
make any Alterations so that should such Alterations be performed, the Tenant
will be aware of such conditions. Such pre-existing conditions might include the
presence of hazardous substances or hidden utility conduit for example.
Notwithstanding Landlord's review of plans and whether or not Landlord consents
to such work, Tenant and not Landlord shall be responsible for compliance of
such plans and of Tenant's work with all applicable laws, ordinances and
regulations of all governmental authorities, including, without limitation,
Title III of the Americans with Disabilities Act of 1990, all regulations issued
thereunder and the Accessibility Guidelines for Buildings and Facilities issued
pursuant thereto, as the same are in effect on the date hereof and as may be
hereafter modified, amended or supplemented. Landlord may impose reasonable
requirements as a condition of such consent including without limitation the
submission of plans and specifications for Landlord's prior written approval,
obtaining necessary permits, posting bonds, obtaining insurance, prior approval
of contractors, subcontractors and suppliers, prior receipt of copies of all
contracts and subcontracts, contractor and subcontractor lien waivers,
affidavits listing all contractors, subcontractors and suppliers, use of union
labor (if Landlord uses union labor), affidavits from engineers acceptable to
Landlord stating that the Alterations will not adversely affect the mechanical
or utility systems and equipment or the structure of the Building, and
requirements as to the manner and times in which such Alterations shall be done.
All Alterations shall be performed in a good and workmanlike manner and all
materials used shall be of a quality comparable to or better than those in the
Premises and Development and shall be in accordance with plans and
specifications approved by Landlord, and Landlord may require that all such
Alterations be performed under Landlord's supervision. In all cases, Tenant
shall pay Landlord a reasonable fee to cover Landlord's overhead in reviewing
Tenant's plans and specifications and performing any supervision of the
Alterations. If Landlord consents or supervises, the same shall not be deemed a
warranty as to the adequacy of the design, workmanship or quality of materials,
and Landlord hereby expressly disclaims any responsibility or liability for the
same. Landlord shall under no circumstances have any obligation to repair,
maintain or replace any portion of the Alterations.

     (b) It is distinctly understood that all Alterations upon the Demised
Premises (whether with or without Landlord's consent) shall at the election of
Landlord remain upon the Demised Premise and be surrendered with the Demised
Premises at the expiration of this Lease without disturbance, molestation or
injury. Should Landlord elect that Alterations upon Demised Premises be removed,
upon lease expiration or earlier termination of this Lease, Tenant hereby agrees
to cause same to be removed at Tenant's sole cost and expense and deliver up the
Demised Premises in accordance with the standard set forth in Section 8 hereof;
and should Tenant fail to remove and restore the same, then and in such event,
Landlord shall cause same to be removed at Tenant's expense and Tenant hereby
agrees to reimburse Landlord for the cost of such removal and restoration
together with any and all damages which Landlord may suffer and sustain by
reason of the failure of Tenant to remove and restore the same.

     (c) All additions, decorations, fixtures, hardware, non-trade fixtures and
all improvements, temporary or permanent, in or upon the Premises, whether
placed there by the Tenant or by the Landlord, shall, unless the Landlord
requests their removal, become the Landlord's property and shall remain upon the

                                       15
<PAGE>

Premises at the expiration of this Lease, by lapse of time or otherwise, without
compensation or allowance or credit to the Tenant. Landlord may, at its sole
option, request Tenant, at Tenant's sole cost, to remove same and if, upon the
Landlord's request, the Tenant does not remove said additions, decorations,
fixtures, hardware, non-trade fixtures and improvements, the Landlord may remove
the same, and the Tenant shall pay the cost of such removal to the Landlord upon
demand as additional rent. These obligations of Tenant shall survive the
expiration or earlier termination of this Lease.

     12. Rules and Regulations. Tenant agrees for itself, its employees,
contractors, agents, invitees and licensees, to comply with the rules and
regulations ("Rule ") set forth in Exhibit "B" attached to this Lease. Landlord
shall have the right to reasonably amend such Rules and supplement the same with
other reasonable Rules (not expressly inconsistent with this Lease) relating to
the Development, or the promotion of safety, care, cleanliness or good order
therein, and all such amendments or new Rules shall be binding upon Tenant after
five (5) days notice thereof to Tenant. All Rules shall be applied on a
non-discriminatory basis, but nothing herein shall be construed to give Tenant
any claim, demand or cause of action against Landlord arising out of the
violation of such Rules by any other tenant, occupant, or visitor of the
Development, or out of the enforcement or waiver of the Rules by Landlord in any
particular instance. Any violation by Tenant of any of the Rules may be
restrained; but whether or not so restrained, Tenant shall be and remain liable
for all damages, losses, costs and expenses resulting from any violation
thereof. Nothing in this Lease shall be construed to impose upon Landlord any
duty or obligation to enforce said Rules provided that Landlord shall uniformly
apply such Rules and shall not discriminate against Tenant in the enforcement of
any such Rules.

     13. Access to Demised Premises by Landlord. Tenant agrees that it will
allow Landlord, and Landlord's agents or designees, to enter the Demised
Premises at all times to examine, inspect or to protect the same or prevent
damage or injury to the same, or to make such alterations or repairs as Landlord
may deem necessary, or, during the last six (6) months of the Term of this Lease
to exhibit the same to prospective tenants.

     14. Tenant's Repair Obligations. Subject to the provisions of Sections 20
and 22 of this Lease, Tenant shall at its own cost and expense keep and maintain
all parts of the Demised Premises and such portion of the Development within the
exclusive control of Tenant in good and sanitary condition, and in working order
and repair promptly making all necessary repairs and replacements, whether
ordinary or extraordinary, with materials dn workmanship of the same character,
kind and quality as the original, including but not limited to, doors, any
special office entries, interior walls and furnish work, floor coverings,
electrical systems and fixtures, and plumbing work and fixtures, reasonable wear
and tear accepted. All such repairs and replacements shall be made under the
supervision and with the prior written approval of Landlord, using contractors
acceptable to Landlord. Tenant shall not damage any demising wall or disturb the
integrity and supports provided by any demising wall and shall, at its sole cost
and expense, properly repair any damage or injury to any demising wall caused by
Tenant or its employees, agents or invitees. Tenant shall, at its own cost and
expense, as additional rent, pay for the repair of any damage to the Demised
Premises, the Building, or the Development resulting from and/or caused in whole
or in part by the negligence or misconduct of Tenant, its agents, contractors,
employees, invitees, sublessees, assignees, licensees, or any other person
entering upon the Development as a result of Tenant's business activities or
caused by Tenant's default hereunder. All injury to the Demised Premises or the
Development caused by moving property of Tenant into, in or out of, the Building
and all damages caused by Tenant, or the agents, contractors, licensees,
sublessees, assignees, employees and invitees of Tenant shall be repaired by
Tenant, at the expense of Tenant. In the event Tenant shall fail to do so, then
Landlord shall have the right to make such necessary repairs, alterations and
replacements, structural, non-structural or otherwise and 115% of any charge or
cost so incurred by Landlord shall be paid by Tenant as additional rent, payable
with the installment of Rent next becoming due or thereafter falling due under
the terms of this Lease. This provision shall be construed as an additional
remedy granted to or and not in limitation of any rights and remedies which
Landlord has or may have in said circumstances.

     15. Landlord's Repair Obligations. Subject to the provisions of Sections
14, 20 and 22 hereof, Landlord shall maintain in good repair, reasonable wear
and tear accepted, all parts of the Development, other than the Demised Premises
or portions of the Development within the exclusive control of tenants of the
Development, making all necessary repairs and replacements, whether ordinary or
extraordinary, structural or nonstructural, including roof, foundation, walls,
the heating, ventilation and air conditioning systems, downspouts, gutters,
regular moving of any grass, trimming, weed removal and general landscape


                                       16
<PAGE>

maintenance, including exterior painting, exterior lighting, exterior signs and
common sewage plumbing and the maintenance of all paved areas including
driveways and alleys, including, but not limited to, cleaning, repaving,
restripping and resealing. Tenant shall immediately give Landlord written notice
of any defect or need for repairs, after which Landlord shall have a reasonable
opportunity to repair the same or cure such defect. Landlord's liability with
respect to any defects, repairs or maintenance for which Landlord is responsible
under any of the provisions of this Lease shall be limited to the cost of such
repairs or maintenance or the curing of such defect and Landlord shall not be
liable for damages. The term "walls" as used herein shall not include windows,
glass or plate glass, doors, special store front or office entry. Landlord shall
not be liable to Tenant, its employees, agents, invitees, licensees, family
members, guests or trespassers for any damage, compensation or claim arising
from the necessity of repairing any portion of the Development, the interruption
in the use of the Demised Premises, accident or damage resulting from the use or
operation (by Landlord, Tenant or any other person or persons whatsoever) of
elevators, or heating, cooling, electrical or plumbing equipment or apparatus,
or the termination of this Lease by reason of the destruction of the Demised
Premises, or from any fire, robbery, theft, and/or any other casualty, or from
any leakage in any part or portion of the Demised Premises or the Building, or
from water, rain or snow that may leak into, or flow from, any part of the
Demised Premises or the Building, or from drains, pipes or plumbing work in the
Building, or from any other cause whatsoever, unless such damage is proximately
caused by Landlord's negligence. Tenant shall give Landlord prompt notice of any
accident to or defect in the pipes, heating or air conditioning apparatus, or
electric wires or system in order that the same may be remedied by Landlord,
subject, however, to the provisions of Sections 8, 10 and 14 hereof.

     16. Personal Property of Tenants. All personal property of the Tenant in
the Demised Premises or in the Development shall be at the sole risk of the
Tenant. Landlord assumes no liability or responsibility whatsoever with respect
to the conduct and operation of the business to be conducted in Demised Premises
nor for any loss or damage of whatsoever kind or by whomsoever caused, to
personal property, documents, records, monies, or goods of Tenant or to anyone
in or about the Demised Premises by consent of Tenant, unless proximately caused
by negligence on the part of Landlord.

     17. Utilities/Supplies. (a) So long as Tenant is not in default, customary
electric current, water, lavatory supplies, light bulbs and tube replacement,
and automatically operated elevator service shall be provided in the Building
during normal business hours from 7:00 a.m. to 6:00 p.m. Monday through Friday
with Saturdays, Sundays and legal holidays excluded and normal and usual
cleaning and janitorial service nightly, Monday through Friday, after business
hours commencing around 5:00 p.m. Heat and air conditioning shall be furnished
by means of electrically operated combination heating and cooling incremental
units, where installed, and/or by means of a central air conditioning system
during normal business hours during such seasons of the year when such services
are normally and usually furnished in modern office buildings in the area in
which Demised Premises is located.

     (b) Tenant will not install or operate in the Demised Premises any
electrically operated equipment or other machinery, other than personal
computers, typewriters or adding machines, and such other electrically operated
office machinery and equipment normally used in modern offices, without first
obtaining the prior consent in writing of Landlord, who may condition such
consent upon the payment by Tenant of additional rent in compensation for such
excess consumption of water and/or electricity or wiring as may be occasioned by
the operation of said equipment or machinery; nor shall Tenant install any other
equipment whatsoever which will or may necessitate any changes, replacements or
additions to or require the use of the water system, plumbing system, heating
system, air conditioning system or the electrical system of the Demised Premises
without the prior written consent of Landlord.

     (c) Landlord may install and operate meters or any other reasonable system
for monitoring or estimating any services or utilities used by Tenant in excess
of those required to be provided by Landlord under this Section (including a
system for Landlord's engineer to reasonably estimate any such excess usage). If
such system indicates such excess services or utilities, Tenant shall pay
Landlord's reasonable charges for installing and operating such system and any
supplementary air-conditioning, ventilation, heat, electrical or other systems
or equipment (or adjustments or modifications to the existing mechanical or
utility systems and equipment), and Landlord's reasonable charges for such
amount of excess services or utilities used by Tenant.

     (d) Landlord does not warrant that any services or utilities will be free
from shortages, failures, variations, or interruptions caused by repairs,
maintenance, replacements, improvements, alterations, changes of service,

                                       17
<PAGE>

strikes, lockouts, labor controversies, accidents, inability to obtain services,
fuel, steam, water or supplies, governmental requirements or requests, or other
causes beyond Landlord's reasonable control. None of the same shall be deemed an
eviction or disturbance of Tenant's use and possession of the Premises or any
part thereof, or render Landlord liable to Tenant for abatement of Rent, or
relieve Tenant from performance of Tenant's obligations under this Lease.
Accordingly, Landlord in no event shall be liable for damages by reason of loss
of profits, business interruption or other consequential damages.

     (e) In the event Tenant should require cooling or heating after normal and
usual business hours, Tenant shall make sure request to Landlord in writing in
the following manner: (i) for service on Tuesdays through Saturdays, a notice
must be provided prior to noon on the date previous to the date of service need;
and (ii) for service on Sundays and Mondays, a notice must be provided prior to
noon on the previous Friday. The Tenant shall be obligated to pay for such after
hours service in accordance with a schedule of costs as set forth by the
Landlord from time to time. Presently, the hourly service rate is $30.00 per
hour per zone, with a minimum of four hours per service request.

     18. Defaults. Each of the following events shall be deemed to be "Events of
Default" by Tenant under this Lease:

     (a) Tenant shall fail to pay any installment of the Rent herein reserved
when due, or any other payment or reimbursement to Landlord required herein when
due and such failure shall continue for a period of five (5) days after written
notice thereof.

     (b) Tenant or any guarantor of Tenant's obligations hereunder shall
generally not pay its debts as they become due or shall admit in writing its
inability to pay its debts or shall make a general assignment for the benefit of

or other action seeking to have an order for relief entered on its behalf as a
debtor to adjudicate it as bankrupt or insolvent, or seeking reorganization or
relief of debtors or seeking appointment of a receiver, trustee, custodian or
other similar official for it and for all or of any substantial part of its
assets; or Tenant or any such guarantor shall take any action to authorize or in
contemplation of any of the actions set forth above in this Subsection (b);

     (c) Any case, proceeding or other action against Tenant or any guarantor of
Tenant's obligations hereunder shall be commenced seeking to have an order for
relief entered against it as debtor or to adjudicate it as bankrupt or
insolvent, or seeking reorganization, arrangement, adjustment, liquidation,
dissolution or composition of it or its debts under any law relating to
bankruptcy, insolvency, reorganization or relief of debtors, or seeking
appointment of a receiver, trustee, custodian or other similar official for it
or for all or any substantial part of its property;

     (d) A receiver or trustee shall be appointed for all or substantially all
of the assets of the Tenant or any guarantor of Tenant's obligations hereunder;

     (e) Tenant shall fail to occupy the Demised Premises at the commencement of
the Term or abandon or vacate any substantial portion of the Demised Premises
during the Term;

     (f) Tenant shall fail to discharge any lien placed upon the Demised

     (g) Tenant shall fail to comply with any term, covenant or condition of
this Lease (other than as otherwise stated in this Section 18), and shall not
cure such failure within ten (10) days after written notice thereof by Landlord
to Tenant, provided, if Tenant is diligently undertaking to cure such failure
within such ten (10) day period and such failure cannot reasonably be cured
within such ten (10) day period, Tenant shall have twenty (20) days after said
notice to cure such failure before the failure shall constitute an "Event of
Default";

     (h) Tenant shall fail to continuously operate its business at the Demised
Premises for the permitted use set forth in Section 6 whether or not Tenant is

                                       18
<PAGE>

     (i) Failure by Tenant to cure forthwith, immediately after receipt of
notice, any hazardous or emergency condition which Tenant has created in
violation of this Lease or of law (as used herein the phrase "hazardous or
emergency condition" shall mean a condition which threatens to cause an
immediate harm or is then causing a harm to person(s) or property);

     (j) Failure by Tenant to timely execute, acknowledge and deliver forthwith,
a subordination or attornment agreement as required by Section 21 hereof or an

hereto that it will not render its performance under this Lease when the time
fixed for performance arrives.

     19. Remedies. (a) Upon the occurrence of any "Event of Default" described
in Section 18 hereof, which has not been cured or remedied during the applicable
grace period, if any, Landlord shall have the option to pursue any one or more
of the following rights or remedies without any notice or demand whatsoever all
of which shall be distinct, separate and cumulative and shall not operate to
exclude or deprive Landlord of any other right or remedy allowed it by law:

          (i) Landlord may terminate this Lease by giving to Tenant at least
     five (5) days written notice of the Landlord's election to do so, in which
     event the Term of this Lease shall end, and all right, title and interest
     of the Tenant hereunder shall expire, on the date stated in such notice;

          (ii) Landlord may terminate Tenant's right to possession of the
     Demised Premises without terminating this Lease by giving at least five (5)
     days written notice to Tenant that Tenant's right of possession shall end
     on the date stated in such notice, whereupon the right of the Tenant to
     possession of the Demised Premises or any part thereof shall cease on the
     date stated in such notice; and

          (iii) Landlord may enforce the provisions of this Lease and may
     enforce and protect the rights of the Landlord hereunder by a suit or suits
     in equity or at law for the specific performance of any covenant or
     agreement contained herein, or for the enforcement of any other appropriate
     legal or equitable remedy, including recovery of all monies due or to
     become due from the Tenant under any of the provisions of this Lease.

     (b) If Landlord exercises either of the remedies provided in Subsection (i)
or (ii) of Section 19(a), Tenant shall surrender possession and vacate the
Demised Premises immediately, and deliver possession thereof to Landlord in
"broom clean" condition, and Landlord may then and at any time thereafter
re-enter and take complete and peaceful possession of the Demised Premises with
or without process of law, full and complete license to do so being hereby
granted to Landlord, and Landlord may expel or remove Tenant and any others who
may be occupying or within the Demised Premises and remove any and all property
therefrom, using such force as may be necessary, without being deemed in any
manner guilty of trespass, eviction or forcible entry or detainer, and without
relinquishing Landlord's right to Rent, or any other right given to Landlord
hereunder or by operation of law.

     (c) If Landlord, pursuant to the provisions of Section 19(a) hereof,
terminates the right of the Tenant to possession of the Demised Premises without
terminating this Lease, such termination of possession shall not release Tenant
in whole or in part, from Tenant's obligation to pay Rent hereunder for the full
Term, and Landlord shall have the right from time to time, to recover from
Tenant and Tenant shall remain liable for all Annual Base Rent, additional rent
and any other sums accruing as they become due under the Lease during the period
from the date stated in the notice terminating possession to the stated end of
the term. The Landlord may, in its discretion, relet the Demised Premises or any
part thereof for such rent, for such time (which may be for a term extending
beyond the Term of this Lease) and upon such terms as the Landlord in the
Landlord's sole discretion shall determine, but the Landlord shall not be

                                       19
<PAGE>

required to relet the Demised Premises or to observe any instructions given by
the Tenant relative to such reletting. If Landlord relets the Demised Premises,
the Landlord may make repairs, alterations and additions in or to the Demised
Premises and redecorate the same to the extent deemed by the Landlord necessary
or desirable and, in connection therewith, change the locks to the Demised
Premises, and the Tenant shall upon demand pay the cost thereof together with
the Landlord's expenses of reletting. Landlord may collect the rents from any
such reletting and apply the same first to the payment of the expenses of
reentry, redecoration, repair and alterations and the expense of reletting and
second to the payment of Rent herein provided to be paid by the Tenant, and any
excess or residue shall operate only as an offsetting credit against the amount
of Rent as the same thereafter becomes due and payable hereunder, but the use of
such offsetting credit to reduce the amount of Rent due Landlord, if any, shall
not be deemed to give Tenant any right, title or interest in or to such excess
or residue and any such excess or residue shall belong to Landlord solely;
provided that in no event shall Tenant be entitled to a credit on its
indebtedness to Landlord in excess of the aggregate sum (including Annual Base
Rent and additional rent) which would have been paid by Tenant for the period
for which the credit to Tenant is being determined, had no Event of Default
occurred. No such re-entry or repossession, repairs, alterations and additions,
or reletting shall be construed as an eviction or ouster of the Tenant or as an
election on Landlord's part to terminate this Lease unless a written notice of
such intention be given to Tenant or shall operate to release the Tenant in
whole or in part from any of the Tenant's obligations hereunder, and the
Landlord may, at any time and from time to time, sue and recover judgment for
any deficiencies from time to time of the proceeds of any such reletting.

     (d) In the event of the termination of this Lease by Landlord as provided
in Subsection (i) of Section 19(a), Landlord shall be entitled to recover from
Tenant all the fixed dollar amounts of Rent accrued and unpaid for the period up
to and including such termination date, as well as all other additional sums
payable by the Tenant, or for which Tenant is liable or in respect of which
Tenant has agreed to indemnify Landlord under any of the provisions of this
Lease which may be then owing and unpaid, and all costs and expenses, including
court costs and attorneys' fees incurred by Landlord in the enforcement of its
rights and remedies hereunder, and in addition Landlord shall be entitled to
recover as damages for loss of the bargain and not as a penalty (w) the
unamortized cost to the Landlord, computed and determined in accordance with
generally accepted accounting principles, of the tenant improvements and
alterations, if any, paid for and installed by Landlord pursuant to this Lease,
(x) the unamortized cost of lease commissions paid in respect of this Lease, (y)
the aggregate sum which at the time of such termination represents the excess,
if any, of the present value of the aggregate Rents (inclusive of the amounts
projected by Landlord to represent additional rent in respect of Operating
Expenses and Taxes) at the annual rate or respective annual rates for the
remainder of the term as then in effect pursuant to the applicable provisions of
this Lease, over the then present value of the then aggregate fair rental value
of the Demised Premises for the balance of the Term, such present worth to be
computed in each case on the basis of a per annum discount at one-half (<<) of
the corporate base rent of interest then in effect at the First National Bank of
Chicago from the respective dates upon which such rentals would have been
payable hereunder had this Lease not been terminated, and (z) any damages in
addition thereto, including reasonable attorneys' and consultants fees and court
costs, which Landlord shall have sustained by reason of the breach of any of the
provisions of this Lease other than for the payment of Rent.

     (e) Tenant hereby grants Landlord a first lien upon the interest of Tenant
under this Lease to secure the payment of moneys due under this Lease, which
lien may be enforced in equity and landlord shall be entitled as a matter of
right to have a receiver appointed to take possession of the Demised Premises
and relet the same under order of court. Tenant's obligation to pay Rent during
the Term of the Lease shall continue and shall not be waived, released or
terminated by the service of a five-day notice, demand for possession, the
filing of a forcible entry and detainer action or judgment for possession or any
other act resulting in the termination of Tenant's right to possession.

     (f) All Rent and other amounts owed by Tenant to Landlord under this Lease
shall bear interest from the date due until the date paid at either (i) a rate
of interest equal to the highest prime rate of interst quoted in the Wall Street
Journal money rates column on the first business day after the date such payment
was due plus five percent (5%); or (ii) at the maximum legal rate of interest,
whichever is lower. Unless otherwise designated in this Lease all amounts owing
to Landlord are to be paid within ten (10) days from the date Landlord renders a
statement therefor to Tenant.

     (g) In the event of any litigation between the parties, the prevailing
party shall be entitled to obtain, as part of the judgment, all reasonable
attorneys' and consultants' fees, costs and expenses incurred in connection with

                                       20
<PAGE>

such litigation, except as may be limited by applicable Law. THE PARTIES HERETO
SHALL, AND THEY HEREBY DO, WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM BROUGHT BY EITHER OF THE PARTIES HERETO AGAINST THE OTHER ON ANY
MATTERS WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE, THE
RELATIONSHIP OF LANDLORD AND TENANT, TENANT'S USE OR OCCUPANCY OF THE DEMISED
PREMISES, AND/OR ANY CLAIM FOR INJURY OR DAMAGE. TENANT ALSO AGREES TO WAIVE ANY
AND ALL COUNTERCLAIMS TENANT MAY HAVE IN ANY SUIT FOR POSSESSION BY LANDLORD; IT
BEING UNDERSTOOD THAT THE SUBJECT OF ANY SUCH COUNTERCLAIM MAY BE ASSERTED BY
TENANT BUT ONLY IN A SEPARATE ACTION BROUGHT BY TENANT AGAINST LANDLORD.

     (h) If Tenant shall file for protection under any chapter of the U.S.
Bankruptcy Code now or hereinafter in effect, Landlord and Tenant agree, to the
extent permitted by law, to demand that the debtor-in-possession or trustee-
in-bankruptcy, if one is appointed, assume or reject this Lease within sixty
(60) days after such filing.

     (i) Tenant shall pay, as additional rent, a service charge of Two Hundred
Dollars ($200.00) for bookkeeping and administrative expenses, if Rent is not
received within five (5) days after its due date. Such service charge shall not
be deemed a consent by Landlord to late payments, nor a waiver of Landlord's
right to insist upon timely payments at any time, nor a waiver of any remedies
to which Landlord is entitled as a result of the late payment of Rent.

     (j) In the event Tenant's check, given to Landlord in payment of Rent, is
returned by the bank for non-payment, Tenant agrees to pay all expenses incurred
by Landlord as a result thereof.

     (k) In the event that Tenant abandons any personal property or fixtures at
the Demised Premises, including that which is owned or leased to Tenant,
Landlord shall also have the right to remove from the Demised Premises (without
the necessity of obtaining a distress warrant, writ of sequestration or other
legal process) all or any portion of such personal property or fixtures located
thereon and to place same in storage; and in such event, Tenant shall be liable
to Landlord for costs incurred by Landlord in connection with such removal and
storage. Landlord shall also have the right to relinquish possession of all or
any portion of such personal property or fixtures to any person ("Claimant")
claiming to be entitled to possession thereof who presents to Landlord a copy of
any instrument represented to Landlord by Claimant to have been executed by
Tenant (or a predecessor Tenant) granting Claimant the right under various
circumstances to take possession of such personal property or fixtures, without
the necessity on the part of Landlord to inquire into the authenticity of said
instrument's copy of Tenant's or Tenant's predecessor's signature(s) thereon and
without the necessity of Landlord making any nature of investigation or inquiry
as to the validity of the factual or legal basis upon which Claimant purports to
act; and Tenant agrees to indemnify, defend and hold Landlord harmless from all
cost, expense, loss, damage and liability incident to Landlord's relinquishment
of possession of all or any portion of such furniture, shelves, bins, machinery
or other trade fixtures to Claimant. Any and all property which may be removed
from the Demised Premises by Landlord pursuant to the authority of this Lease or
of Law, to which Tenant is or may be entitled, may be handled, removed and
stored, as the case may be, by or at the direction of the Landlord at the risk,
cost and expense of Tenant, and Landlord shall in no event be responsible for
the value, preservation or safekeeping thereof. Tenant shall pay to Landlord,
upon demand any and all expenses incurred in such removal and all storage
charges against such property so long as the same shall be in Landlord's
possession or under Landlord's control. Any such property of Tenant not retaken
by Tenant from storage within thirty (30) days after the removal from the
Demised Premises shall conclusively be presumed to have been conveyed by Tenant
to Landlord under this Lease as a bill of sale without further payment or credit
by Landlord to Tenant.

     (l) No receipt of moneys by Landlord from Tenant after termination of this
Lease or Tenant's right to possession, or after the giving of any notice of
termination of this Lease or Tenant's right to possession, shall reinstate,
continue or extend the Term of this Lease or affect any notice theretofore given
to Tenant, or operate as a waiver of the right of Landlord to enforce the
payment of rent and any other sum or sums of money and other charges herein
reserved and agreed to be paid by Tenant then due or thereafter falling due, or
operate as a waiver of the right of Landlord, to recover possession of the

                                       21
<PAGE>

Demised Premises by proper remedy, except as herein otherwise expressly
provided, it being agreed that after the service of notice to terminate this
Lease or Tenant's right to possession or the commencement of suit or summary
proceedings, or after final order or judgment for the possession of the Demised
Premises, Landlord may demand, receive and collect any moneys due or thereafter
falling due without in any manner affecting such notice, proceeding, order, suit
or judgment, except as herein otherwise specifically provided, all such moneys
collected being deemed payments on account of the use and occupation of the
Demised Premises, or at the election of Landlord, on account of Tenant's
liability hereunder. Further, no payment by Tenant or receipt by Landlord of a
lesser amount than any installment or payment of Rent due shall be deemed to be
other than on account of the amount due, and no endorsement or statement on any
check or payment of Rent shall be deemed an accord and satisfaction. Landlord
may accept such check or payment without prejudice to Landlord's right to
recover the balance of such installment or payment of Rent, or pursue any other
remedies available to Landlord. If Landlord shall direct Tenant to pay Annual
Base Rent or additional rent (or both, as the case may be) to a "lockbox" or
other depository whereby payments issued in payment of Annual Base Rent or
additional rent (or both, as the case may be) are initially cashed or deposited
by a person or entity other than Landlord (albeit on Landlord's authority),
then, for any and all purposes under this Lease; (i) Landlord shall not be
deemed to have accepted such payment until ten (10) days after the date on which
Landlord shall have actually received such funds; and (ii) Landlord shall be
deemed to have accepted such payment if (and only if) within said ten (10) day
period, Landlord shall not have returned (or attempted to return) such payment
to Tenant. Nothing contained in the immediately preceding sentence shall be
construed to place Tenant in default of Tenant's obligation to pay Rent if and
for so long as Tenant shall timely pay the Rent required pursuant to this Lease
in the manner designated by Landlord. TENANT HEREBY WAIVES ANY AND ALL RIGHTS OR
REDEMPTION OR RESTORATION OF THE OPERATION OF THIS LEASE CONFERRED BY ANY
PRESENT OR FUTURE LAW, STATUTE OR OTHERWISE UPON THE EXPIRATION OR SOONER
TERMINATION OF THE TERM, THE ENTRY OF FINAL UNAPPEALABLE JUDGMENT FOR RECOVERY
OF POSSESSION THROUGH ANY ACTION OR PROCEEDING, OR LANDLORD'S OBTAINING
POSSESSION OF THE DEMISED PREMISES UNDER THE TERMS OF THIS LEASE.

     (m) The rights of Landlord stated in this Section 19 shall be in addition
to any and all other rights which Landlord has or may hereafter have at law or
in equity; and Tenant stipulates and agrees that the rights herein granted
Landlord are commercially reasonable.

     (n) If under the provisions hereof, Landlord shall institute proceedings
and/or a compromise or settlement thereof shall be made, the same shall not
constitute a waiver of any covenant herein contained nor of any of Landlord's
rights hereunder. No waiver by Landlord of any breach of any covenant, condition
or agreement herein contained shall operate as a waiver of such covenant,
condition, or agreement itself, or of any subsequent breach thereof. No payment
by Tenant or receipt by Landlord of a lesser amount than the monthly
installments of Rent herein stipulated shall be deemed to be other than on
account of the earliest stipulated Rent nor shall any endorsement or statement
on any check or letter accompanying a check for payment of Rent 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 to pursue
any other remedy provided in this Lease. No re-entry by Landlord, and no
acceptance by Landlord of keys from Tenant, shall be considered an acceptance of
a surrender of the Lease.

     (o) If Landlord is required to deliver to Tenant more than two (2) written
notices of default pursuant to Subsection 19(a) hereof during the Term, then
Tenant shall pay to Landlord commencing with the third such notice delivered to
Tenant and continuing with each notice delivered to Tenant thereafter, as
additional rent, the sum of $50.00 for each default notice sent, due and payable
by Tenant together with the next due monthly installment of Rent.

     (p) Tenant hereby waives its right to plead any counterclaim unrelated to
this Lease or Tenant's occupancy of the Premises, or to seek an offset, in any
action or proceeding brought by Landlord against Tenant for non-payment of Rent
or default hereunder. This shall not, however, be construed as waiver of
Tenant's right to assert any claim in separate action brought by Tenant.

     20. Fire or Other Casualty. (a) If the Demised Premises, or any part
thereof, shall be damaged or destroyed by fire or other casualty, and if the
Landlord does not elect to terminate this Lease in accordance with the
provisions of Subsection 20(b), then the Landlord shall restore, repair and
replace the Demised Premises, as nearly as possible to its condition immediately
prior to such damage or destruction, and until such repairs have been completed
the Annual Base Rent and all Additional Rent shall be abated in proportion to
the part of the Demised Premises which is rendered

                                       22
<PAGE>


untenantable; provided, however, that the foregoing provisions shall not require
the Landlord to repair, restore or rebuild Tenant's fixtures, equipment,
additions, alterations, improvements, or other appurtenances therein. Such
restoration, repairs and replacement shall be commenced with due diligence and
in good faith as soon as practicable after the occurrence of the casualty (due
allowance being made for the time taken for settlement of the insurance claims,
the time required by Landlord to obtain the permission of governmental
authorities to make such restoration, repair and replacement and other delays
due to causes beyond Landlord's reasonable control), shall be prosecuted with
due diligence and in good faith and, subject to delays caused by circumstances
beyond Landlord's reasonable control, shall be completed within nine (9) months
from the date of occurrence of the casualty.


     (b) If the Demised Premises, or any part thereof, shall be damaged or
destroyed by fire or other casualty, then Landlord shall have the right, by
giving written notice to Tenant within ninety (90) days after the occurrence of
the casualty, to terminate this Lease. If Landlord elects to terminate this
Lease pursuant to this Section, the Term of this Lease shall cease and terminate
as of the date of giving of such notice, any rents paid by Tenant for a period
of time after the occurrence of the casualty shall be refunded by Landlord, and
neither party shall have any further liability under this Lease for any period
of time after the effective date of termination.

     (c) Tenant hereby releases Landlord and its partners, shareholders,
officers, directors, agents and employees, from any and all liability or
responsibility to Tenant (or to anyone claiming through or under Tenant by way
of subrogation to otherwise) for any loss or damage to Tenant's property covered
by a valid and collectible fire insurance policy with extended coverage
endorsement, even if such fire or other casualty shall have been caused by the
fault or negligence of the Landlord or anyone for whom the Landlord may be
responsible.

     (d) Notwithstanding any provisions in this Section 20 to the contrary,
Landlord shall have no obligation whatsoever to repair, reconstruct or restore
the Demised Premises and/or the Building if any of the following occurs:

          (i) the holder of the first deed of trust, security agreement, or
     mortgage encumbering the Building elects not to permit the insurance
     proceeds payable upon damage to or destruction of the Building or Demised
     Premises to be used for such repair, reconstruction or restoration;

          (ii) the damage or destruction occurs during the last twenty-four (24)
     months of the Lease Term or any renewal or extension thereof;

          (iii) a Default, or an event that, with the giving of notice or
     passage of time, would become a Default; or

          (iv) the Tenant has vacated or abandoned the Demised Premises.

     In any such event, Landlord may terminate this Lease by giving written
notice to Tenant within sixty (60) days after the damage or destruction.

     21. Subordination. (a) This Lease and Tenant's interest hereunder is and
shall be subject and subordinate to the lien of any mortgage or mortgages now or
hereafter placed upon the fee of the land and/or Development of which the
Demised Premises is a part and to any ground lease. Tenant agrees that upon not
less than ten (10) days (which 10 day period is not subject to any notice or
cure periods otherwise provided under this Lease) prior written notice from any
mortgagee or ground lessor or from the Landlord, without charge therefor, it
will, from time to time, execute and deliver any further instruments of
subordination in recordable form required by such mortgagee or ground lessor or
by Landlord to subordinate this Lease and Tenant's interest in the Demised
Premises to the lien of any such mortgage or to any such ground lease and to
attorn and recognize such mortgagee or ground lessor as Tenant's landlord under
this Lease in the event of a foreclosure of the mortgage or cancellation of the
ground lease. In the event of the enforcement by the ground lessor or the
mortgage holder of the remedies provided by law or by any mortgage securing
mortgage holder or any foreclosure sale or proceedings in lieu thereof or final
determination for possession in favor of the ground lessor, Tenant will, upon
request of any person succeeding to the interest of Landlord, as the result of
said enforcement, automatically become the Tenant of any successor in interest,
without changing the terms or other provisions of this


                                       23
<PAGE>

Lease; provided, however, that said successor in interest shall not (i) be
liable for any previous act or omission of Landlord under this Lease; (ii) be
subject to any offset which shall theretofore have accrued to Tenant against the
Landlord; (iii) have any obligation with respect to any security deposited under
this Lease unless such security shall have been physically delivered to the
mortgagee or ground lessor or their successors in interest; or (iv) be bound by
any previous modification of this Lease or by any previous payment of Rent for a
period greater than one month, unless such modification or prepayment shall has
been expressly approved in writing by the mortgagee or ground lessor or their
successors in interest. Landlord shall, upon request by any person succeeding to
the interest of Tenant, execute and deliver an instrument or instruments
confirming its attornment.

     (b) Wherever the terms "mortgage" or "mortgagee" are used in this Lease,
they shall be deemed to mean and include, respectively (i) mortgages, deeds of
trust or other similar instruments and modifications, consolidation, extensions,
renewals, replacements and substitutes thereof and all advances thereunder; and
(ii) the holder of such mortgage. Wherever the terms "ground lease" or "ground
lessor" are used in this Lease, they shall be deemed to mean and include
respectively, (i) any lease of the entire fee of the land upon which the
Building is located or a lease of the said land together with any part of the
improvements on said land, and all amendments, modifications, extensions and
substitutes thereof; and (ii) the landlord of any such ground lease. Tenant
hereby irrevocably constitutes and appoints Landlord as Tenant's
attorney-in-fact to execute, acknowledge and deliver any and all such
instruments for an on behalf of Tenant.

     (c) Notwithstanding any other provision to the contrary, Landlord shall use
it's best efforts to obtain from any future lender a non-disturbance agreement
that provides that so long as Tenant is not in default under the Lease beyond
any applicable cure period, the lender will (i) no disaffirm the Lease; (ii) not
disturb Tenant's possession or use of the Premises; (iii) affirmatively
recognize the validity of the Lease; and (iv) assume all of Landlord's
obligations under the Lease.

     22. Condemnation. If the whole or a substantial part of the Demised
Premises shall be taken of condemned by any governmental authority for any
public or quasi-public use of purpose (including sale under threat of such a
taking), then the Term of this Lease shall cease and terminate as of the date
when title vests in such governmental authority, and the Rent shall be abated
for the period after the date when such title vests in such governmental
authority. If less than a substantial part of the Demised Premises is taken or
condemned by any governmental authority for any public or quasi-public use or
purpose, the Rent shall be equitably adjusted on the date when title vests in
such governmental authority and the Lease shall otherwise continue in full force
and effect. Tenant shall have no claim against Landlord (or otherwise) for any
portion of the amount that may be awarded as damages as a result of any
governmental taking or condemnation (or sale under threat of such taking or
condemnation) or for the value of any unexpired Term of the Lease.

     23. Holding Over. It is further understood and agreed by and between the
parties hereto that, in the event Tenant shall not immediately surrender the
Demised Premises on the day after the Expiration Date, then Tenant shall, by
virtue of this Lease, become a tenant by the month at one and one half the
rental per month of the monthly installment of Annual Base Rent and all
Additional Rent due for the last month of the last lease year, commencing said
monthly tenancy with the first day next after the Expiration Date; and Tenant as
a monthly tenant shall be subject to all conditions and covenants of this Lease
insofar as the same are applicable, or as the same shall be adjusted, to a
month-to-month tenancy; and said Landlord shall give Tenant at least thirty (30)
days' written notice to quit said premises, except in the event of non-payment
of rent in advance or of breach of any other covenant by said Tenant, in which
event said Tenant shall hold over after the expiration of the term hereby
created, and if Landlord shall desire to regain possession of said premises
promptly at the expiration date, then at any time prior to Landlord's acceptance
of rent from Tenant as a monthly tenant hereunder; Landlord at its option, may
forthwith re-enter and take possession of said premises without process, or by
any legal process in force in the State, City or County in which subject
property is located.

     24. Landlord Advances. If Landlord shall incur any charge or expense on
behalf of Tenant under the terms of this Lease or through a separate agreement
relating to the Demised Premises, including but not limited to tenant work, such
charge or expense shall be considered additional rent hereunder; in addition to
and not in limitation of any other rights and remedies which Landlord may have

                                       24
<PAGE>

in case of the failure by Tenant to pay such sums when due, such non-payment
shall entitle Landlord the remedies available to it hereunder for non-payment of
rent. All such charges or expenses shall be paid to Agent at the address set
forth in Section 3 hereof or at such other place and to such other person as
Landlord may from time to time designate in writing.

     25. Security Deposit. Simultaneously with the execution of this Lease,
Tenant shall deposit with Landlord the security deposit sum described in
Subsection 1(u) hereof. Such security deposit (which shall not bear interest to
Tenant) shall be considered as security for payment and performance by Tenant of
all of Tenant's obligations, covenants, conditions and agreements under this
Lease. Upon the expiration of the Term hereof, Landlord shall (provided that
Tenant is not in default under the terms hereof) return and pay back such
security deposit to Tenant less such portion thereof as Landlord shall deem
necessary to make good any default by Tenant with respect to any of Tenant's
aforesaid obligations, covenants, conditions or agreements. In the event of any
default by Tenant hereunder, Landlord shall have the right, but shall not be
obligated, to apply all or any portion of the security deposit to cure such
default, in which even Tenant shall be obligated to promptly deposit with
Landlord the amount necessary to restore the security deposit to its original
amount. In the event of the sale or transfer of Landlord's interest in the
Development, Landlord shall have the right to transfer the security deposit to
such purchaser or transferee, in which event Tenant shall be entitled to look to
the new landlord for the return of the security deposit and Landlord shall
thereupon be released from all liability to Tenant for the return of such
security deposit.

     26. No Further Representations. Neither Landlord nor any agent or employee
of Landlord has made any representations or promises with respect to the Demised
Premises or the Development except as herein expressly set forth, and no rights,
privileges, easements or licenses are acquired by Tenant except as herein
expressly set forth.

     27. Force Majeure. Landlord shall not be required to perform any of its
obligations under this Lease, nor be liable for loss or damage for failure so to
do, nor shall Tenant thereby be released from any of its obligations under this
Lease, where such failure arises from or through acts of God, strikes, lockouts,
labor difficulties, material shortages, explosions, sabotage, accidents, energy
crises, riots, civil commotions, acts of war, results of any warfare or warlike
conditions in this or any foreign country, fire and casualty, legal
requirements, or other causes beyond the reasonable control of Landlord. If
Landlord is so delayed or prevented from performing any of its obligations
during the Term of this Lease, the period of such delay or such prevention shall
be deemed added to the time herein provided for the performance of any such
obligation, but the Term hereof shall not thereby be extended. Except as
otherwise set forth in this Section 27, time is of the essence with respect to
the performance of every provision of this Lease in which time or performance is
a factor.

     28. Estoppel Certificates. Tenant shall, without charge therefor, at any
time and from time to time, within ten (10) days (which ten [10] day period is
not subject to any notice or cure periods otherwise provided under this Lease)
after request therefore by Landlord, execute, acknowledge and deliver to
Landlord a written estoppel certificate certifying to Landlord, any mortgagee,
assignee of a mortgagee, or any purchaser, of the Development or portion
thereof, or any other person designated by Landlord, as of the date of such
estoppel certificate, (i) that Tenant is in possession of the Demised Premises,
(ii) that this Lease is unmodified and in full force and effect (of if there has
been a modification, that the same is in full force and effect as modified and
setting forth such modification); (iii) whether or not there are then existing
any set-offs or defenses against the enforcement of any right or remedy of
Landlord, or any duty or obligation of Tenant hereunder (and, if so, specifying
the same in detail); (iv) the dates, if any, to which any Rent or other charges
have been paid in advance; (v) that Tenant has no knowledge of any then uncured
defaults on the part of Landlord under this Lease (or if Tenant has knowledge of
any such uncured defaults, specifying the same in detail); (vi) that Tenant has
no knowledge of any event having occurred that authorizes the termination of
this Lease by Tenant (or if Tenant has such knowledge, specifying the same in
detail); and (vii) the amount of any security deposit held by Landlord. In the
event Tenant should refuse or fail to execute, acknowledge and deliver said
statement and/or certificate within the time set forth above, such failure or
refusal shall constitute a material default and in addition to any other
remedies Landlord may have, Landlord shall have the right to cancel this Lease
by giving Tenant an additional ten (10) days notice in writing whereupon if the
statement or certificate is not executed and delivered within such ten (10) day
period of this Lease shall be terminated and rendered of no further force and
effect. If Tenant fails to execute and deliver any such instrument or statement
within the initial ten (10) day period set forth above, Tenant irrevocably

                                       25
<PAGE>

appoints Landlord as its attorney-in-fact, in Tenant's name, to execute and
deliver such certificate or statement and Tenant shall be deemed to have agreed
with the matters set forth therein.

     29. Real Estate Brokers. Landlord and Tenant each represent and warrant to
the other that, except as specified in Subsection 1(t) hereof, neither of them
has employed any broker in carrying on the negotiations relative to this Lease.
Landlord and Tenant shall each indemnify and hold harmless the other from and
against any claim or claims for brokerage or other commission arising from or
out of any breach of the foregoing representation and warranty.

     30. Common Areas. Landlord hereby grants to Tenant a non-exclusive right,
in common with Landlord and the other tenants of the Development, to use, and to
permit its employees, customers and business invites to use, (1) the entrances,
exits, corridors, elevators, stairways and other public areas of the Building
for access to the Demised Premises from the public streets adjacent to the
Building; (2) the public conveniences, if any, of the Development; and (3) all
other areas in the Development used in common by tenants of the Development,
such public areas, public conveniences and other areas being hereinafter
referred to collectively as the "common area". All common areas shall be and
remain at all times subject to the exclusive control and management of Landlord
and Landlord shall have the right from time to time to establish reasonable
rules and regulations governing the use of the common areas. Landlord reserves
the right to make changes, additions, alterations or improvements in and to the
common areas and to close the same temporarily for such purposes, or to prevent
the acquisition by the public of right in the common areas or to discourage
non-customer use thereof.

     31. Mechanics' Liens. In the event that any mechanic's lien is filed
against the Demised Premises or the Building or the Development as a result of
additions, alterations, repairs, installations or improvements made by or on
behalf of Tenant, or any other work or act of Tenant, its agents or employees,
Tenant shall discharge the same within twenty (20) days from the filing thereof.
If Tenant fails to discharge any such mechanic's lien, Landlord, at its option,
in addition to all other rights or remedies herein provided, may bond or pay
said lien or claim without inquiring into the validity thereof for the account
of Tenant, and all sums so advanced by Landlord shall be paid in full by Tenant
to Landlord as additional rent on demand.

     32. Notices. All notices and demands which may or are to be required or
permitted to be given by either party on the other hereunder shall be in
writing. All notices and demands shall be sent either by (i)United States Mail,
postage prepaid, certified mail/return receipt requested; or (ii) by personal
service to a representative of the receiving party; or (iii) by nationally
recognized overnight air courier service; addressed as set forth in Subsections
1(b) and 1(d) or to such other person or place as may from time to time be
designated in a notice to the applicable party hereto. If Tenant is a
corporation, a notice or demand may be served on its registered agent in lieu of
service on Tenant. Any such notice or demand shall be deemed given on the
earliest of (a) on the date which is two (2) business days after deposit in an
official U.S. Mail receptacle if delivered via the United States Mail; (b)on the
first business day after deposit with an overnight air courier service with
instructions to deliver on the next business day; or (c) on the date of actual
delivery. If a party refuses to accept a notice or demand, the notice or demand
will be deemed to have been delivered on the date tendered, but rejected. If a
notice or demand is sent via U.S. mail or overnight courier service and that
service has a labor strike or work stoppage or catastrophic event during the
period that such notice or demand is in their possession then such notice or
demand shall not be deemed received until actual delivery. Notwithstanding the
foregoing, notices served with respect to emergency matters may be served
personally or by facsimile or e-mail communication.

     33. Quiet Enjoyment. Subject to the provisions of this Lease, Landlord
covenants that Tenant, on paying the Rent and performing the covenants of this
Lease on its part to be performed, shall and may peaceably have, hold and enjoy
the Demised Premises for the Term.

     34. Rights Reserved to Landlord. Landlord reserves and may exercise the
following rights without affecting Tenant's obligations hereunder:

          (a) To change the name or the street address of the Building or the
     Development;

          (b) To install and maintain a sign or signs on the exterior of the
     Building;

          (c) To designate all sources furnishing sign painting and lettering,
     lamps and bulbs used on the Demised Premises;

          (d) To retain at all times pass keys to the Demised Premises;

          (e) To grant to anyone the exclusive right to conduct any particular
     business or undertaking in the Building or the Development;

          (f) To change the arrangement and/or location of entrances and
     corridors in and to the Building and to add, remove, rename or modify
     buildings, roadways, parking areas, walkways, landscaping, lakes, grading
     and other improvements in or to the Development;

          (g) To approve the weight, size and location of heavy equipment of
fixtures of Tenant; or

          (h) To change or alter the size, configuration, partitions or office
     designations of all or any of the offices or stores in the commercial area
     of the Building or of the Development, if any.

     36. Environmental Compliance. (a) Tenant shall not cause or permit to occur
any act or practice, that may cause, either intentionally or unintentionally:

          (i) Any violation or breach of any federal, state, or local law,
     ordinance, rule or regulation, now or hereafter enacted, related to or
     covering (I) public environmental, health, safety and welfare conditions
     on, under, or about the Demised Premises; (II) Tenant's use or occupancy of
     the Demised Premises, including, but not limited to, ambient air, soil,
     surface water and ground water conditions or (III) the use, generation,
     testing, storage, treatment, location, release, transportation, discharge
     or disposal of "Hazardous Substances" (as herein defined) (collectively
     "Environmental Laws"); or

          (ii) The use, generation, testing, treatment, location, release,
     manufacture, refining, production, processing, storage, or disposal of any
     Hazardous Substance on, under, or about the Demised Premises, or the
     transportation to or from the Demised Premises of any Hazardous Substance.

     (b) In this connection, Landlord or Landlord's representatives shall have
the right upon twenty-four (24) hour notice to inspect and to perform testing in
the Demised Premises from time to time to confirm Tenant's compliance with this
Section.

     (c) Notwithstanding anything in this Section to the contrary, the various
representations, warranties and covenants made herein pertaining to Hazardous
Substances shall not apply or extend to occasions in which elements, compounds,
substances or materials, which may technically constitute Hazardous Substances,

                                       27
<PAGE>

may have been or may in the future be present or used on the Demised Premises in
small quantities for incidental but appropriate purposes, (i.e. such as printing
ink contained in a photo-copy machine) but only if the same would not give rise
to enforcement actions under, or constitute a material breach or violation of,
applicable Environmental Laws. Tenant shall promptly notify Landlord of: (i) any
enforcement, cleanup or other regulatory action taken or threatened by any
governmental or regulatory authority with respect to the presence of any
Hazardous Material on the Demised Premises or the mitigation thereof from or to
other property; (ii) any demands or claims made or threatened by any party
against Tenant or the Demised Premises relating to any loss of injury relating
from any Hazardous Material; (iii) any release, discharge or non-routine,
improper or unlawful disposal or transportation of any Hazardous Material on or
from the Demised Premises; and (iv) any matters where Tenant is required by Law
to give a notice to any governmental or regulatory authority respecting any
Hazardous Material on the Demised Premises. Landlord shall have the right (but
not the obligation) to join and participate as a party as a party in any legal
proceedings or actions affecting the Demised Premises initiated in connection
with any environmental, health or safety Law. At such times as Landlord may
reasonably request, Tenant shall provide Landlord with a written list
identifying any Hazardous Material then used, stored, or maintained upon the
Demised Premises, the use and approximate quantity of each such material, a copy
of any material safety data sheet ("MSDS") issued by the manufacturer therefor,
written information concerning the removal, transportation and disposal of same,
and such other information as Landlord may reasonably require or as may be
required by law. The term "Hazardous Substances", as used in this Section shall
include the following elements, compounds, substances and materials, without
limitation: flammables; explosives; radioactive materials; toxins; asbestos;
pollutants; contaminants; hazardous wastes; toxic substances or related
materials; petroleum and petroleum products; polychlorinated biphenyls (PCBs);
or any other elements, compounds, substances or materials known to cause cancer,
reproductive toxicity, other physical harm, risk or potential risk to human
health, safety or welfare or to the environment or which would trigger any
employee or community "right to know" or MSDS requirements; and all other
substances declared to be hazardous or toxic under any Environmental Law. Any
violation or breach of the foregoing covenants in this Section shall be deemed a
material Event of Default under this Lease.

     (d) If any Hazardous Substance is released, discharged or disposed of by
Tenant or any other occupant of the Demised Premises, or their employees, agents
or contractors, on or about the Development in violation of the foregoing
provisions, Tenant shall immediately, properly and in compliance with applicable
Laws clean up and remove the Hazardous Substance from the Development and any
other affected property and clean or replace any affected personal property
(whether or not owned by Landlord), at Tenant's expense. Such clean up and
removal work shall be subject to Landlord's prior written approval (except in
emergencies), and shall include, without limitation, any testing, investigation,
and the preparation and implementation of any remedial action plan required by
any governmental body having jurisdiction or reasonably required by Landlord. If
Tenant shall fail to comply with the provisions of this Section within five (5)
days after written notice by Landlord, or such shorter time as may be required
by Law or in order to minimize any hazard to persons or property, Landlord may
(but shall not be obligated to ) arrange for such compliance directly or as
Tenant's agent through contractors or other parties selected by Landlord, at
Tenant's expense (without limiting Landlord's other remedies under this Lease or
applicable Law). If any Hazardous Substance is released, discharged or disposed
of on or about the Development and such release, discharge or disposal is not
caused by Tenant or other occupants of the Demised Premises, or their employees,
agents or contractors, such release, discharge or disposal shall be deemed
casualty damage under Section 20 to the extent that the Demised Premises or
common areas serving the Demised Premises are affected thereby; in such case,
Landlord and Tenant shall have the obligations and rights respecting such
casualty damage provided under Section 20. Tenant's obligations and liabilities
under this Section 36 shall survive the expiration or earlier termination of
this Lease.

     37. Communications and Computer Equipment. (a) Tenant may install,
maintain, replace, remove or use any communications or computer wires, cables,
equipment and related devices (collectively the "Equipment") in and serving the
Premises, provided: (i) Tenant shall obtain Landlord's prior written consent of
the plans and specifications therefor, use an experienced and qualified
contractor approved in writing by Landlord, and comply with all of the other
provisions of Article 9; (ii) any such installation, maintenance, replacement,
removal or use shall comply with all laws applicable thereto and good work
practices, and shall not interfere with the use of any then existing Equipment
at the Property; (iii) an acceptable amount of space for additional Equipment
shall be maintained for existing and future occupants of the Property, as
determined in Landlord's reasonable opinion; (iv) if Tenant at any time uses any
Equipment that may create an electromagnetic field exceeding the normal
insulation ratings of ordinary twisted pair riser cable or cause radiation
higher than normal background radiation, the lines therefor (including riser

                                       28
<PAGE>

cables) shall be appropriately insulated to prevent such excessive
electromagnetic fields or radiation; (v) as a condition to permitting the
installation of new Equipment, Landlord may require that Tenant remove or
relocate existing Equipment located in or serving the Demised Premises; (vi)
Tenant's rights shall be subject to the rights of any regulated telephone
company; and (vii) Tenant shall use Landlord's appropriate form of documentation
relative to Tenant's use of the Equipment and shall pay all costs in connection
with its installation, maintenance, use and removal of the Equipment. Landlord
reserves the right to require that Tenant remove any Equipment located in and
serving the Demised Premises which are installed in violation of these
provisions, or which are at any time in violation of any laws or represent a
dangerous or potentially dangerous condition, within three (3) days after
written notice.

     (b) Landlord may (but shall not have the obligation to): (i) install new
Equipment at the Property; (ii) create additional space for Equipment at the
Property; and (iii) reasonably direct, monitor and/or supervise the
installation, maintenance, replacement and removal of, the allocation and
periodic reallocation of available space (if any) for, and the allocation of
excess capacity (if any) on, any Equipment now or hereafter installed at the
Property by Landlord, Tenant or any other party. Such rights shall not be in
limitation of other rights that may be available to Landlord by Law or
otherwise. If Landlord exercises any such rights, Landlord may charge Tenant for
the costs attributable to Tenant, or may include those costs and all other costs
in Operating Expenses (including without limitation, costs for acquiring and
installing Equipment and risers to accommodate new Equipment and spare
Equipment, any associated computerized system and software for maintaining
records of Equipment connections, and the fees of any consulting engineers and
other experts); provided, any capital expenditures included in Operating
Expenses hereunder shall be amortized (together with reasonable finance
charges).

     (c) Notwithstanding anything to the contrary contained in Section 35,
Landlord reserves the right to require that Tenant remove any or all Equipment
installed by or for Tenant within or serving the Premises upon the expiration or
earlier termination of this Lease, provided Landlord notifies Tenant prior to or
within thirty (30) days following such expiration or termination. Any Equipment
not required to be removed pursuant to this Article shall, at Landlord's option,
become the property of Landlord (without payment by Landlord). If Tenant fails
to remove such Equipment as required by Landlord, or violates any other
provision of this Article, Landlord may, after twenty (20) days written notice
to Tenant, remove such Equipment or remedy such other violation, at Tenant's
expense (without limiting Landlord's other remedies available under this Lease
or applicable Law). Tenant shall not, without the prior written consent of
Landlord in each instance, grant to any third party a security interest or lien
in or on the Equipment, and any such security interest or lien granted without
Landlord's written consent shall be null and void. Except to the extent arising
from the intentional or negligent acts of Landlord or Landlord's agents or
employees, Landlord shall have no liability for damages arising from, and
Landlord does not warrant that the Tenant's use of any Equipment will be free
from the following (collectively called "Equipment Problems"): (x) any
eavesdropping or wire-tapping by unauthorized parties; (y) any failure of any
Equipment to satisfy Tenant's requirements; or (z) any shortages, failures,
variations, interruptions, disconnections, loss or damage caused by the
installation, maintenance, replacement, use or removal of Equipment by or for
other tenants or occupants at the Property, by any failure of the environmental
conditions or the power supply for the Property to conform to any requirements
for the Equipment or any associated equipment, or any other problems associated
with any Equipment by any other cause. Under no circumstances shall any
Equipment Problems be deemed an actual or constructive eviction of Tenant,
render Landlord liable to Tenant for abatement of Rent, or relieve Tenant from
performance of Tenant's obligations under this Lease. Landlord in no event shall
be liable for damages by reason of loss of profits, business interruption or
other consequential damage arising from any Equipment Problems.

     38. Default by Landlord. Landlord shall not be in default unless Landlord
fails to perform obligations required of Landlord within a reasonable time after
written notice, but in no event later than thirty (30) days after written notice
by Tenant to Landlord, and to the holder of the first mortgage covering the
Demised Premises, or to its successor in interest whose name and address shall
have theretofore been furnished to Tenant in writing, specifying therein that
Landlord has failed to perform such obligation; provided, however, that if the
nature of Landlord's obligation is such that more than thirty (30) days are
required for performance then Landlord shall not be in default if Landlord
commences performance within such thirty (30) day period and thereafter
diligently prosecutes the same to completion. In no event shall Tenant have the
right to terminate this Lease as a result of Landlord's default and Tenant's
remedies shall be limited to damages and/or an injunction.

                                       29

     39. Miscellaneous. (a) Words of any gender used in this Lease shall be held
or construed to include any other gender, and words in the singular number shall
be held to include the plural, unless the context otherwise requires.

     (b) The terms, covenants and conditions contained in this Lease shall apply
to, inure to the benefit of, and be binding upon, the parties hereto and upon
their respective heirs, legal representatives, successors and permitted assigns,
except as otherwise herein expressly provided. Landlord shall have the right to
assign any of its rights and obligations under this Lease and Landlord's grantee
or Landlord's successor, as the case may be, shall upon such assignment, become
Landlord hereunder, thereby freeing and relieving the grantor or assignor, as
the case may be, of all covenants and obligations of Landlord hereunder. In the
event of any sale or other transfer of the Development, Landlord and its agents
shall be entirely freed and relieved of all agreements, obligations and
liabilities of Landlord hereunder. Tenant agrees to attorn to such grantee or
successor. Nothing herein contained shall give any other tenant in the
Development or the Building any enforceable rights either against Landlord or
Tenant as a result in the Development or the Building any enforceable rights
either against Landlord or Tenant as a result of the covenants and obligations
of either party set forth herein. If there is more than one Tenant, the
obligations of Tenant shall be joint and several. Any indemnification of,
insurance of, or option granted to Landlord shall also include or be exercisable
by Landlord's agents and employees.

     (c) The captions inserted in this Lease are for convenience only and in no
way define, limit or otherwise describe the scope or intent of this Lease, or
any provision hereof, or in any way affect the interpretation of this Lease.

     (d) This Lease, together with the Exhibits and documents listed in the
Table of Contents hereto (which collectively are hereby incorporated where
referred to herein and made a part hereof as though fully set forth), contains
all the terms and provisions between Landlord and Tenant relating to the matters
set forth herein and no prior or contemporaneous agreement or understanding
pertaining to the same shall be of any force or effect, except any such
contemporaneous agreement specifically referring to and modifying this Lease,
signed by both parties. Without limitation as to the generality of the
foregoing, Tenant hereby acknowledges and agrees that Landlord's management,
brokerage and field personnel are only authorized to show the Premises and
negotiate terms and conditions for leases subject to Landlord's final approval,
and are not authorized to make any agreements, representations, understandings
or obligations, binding upon Landlord, respecting the condition of the Demised
Premises or Development, suitability of the same for Tenant's business, or any
other matter, and no such agreements, representations, understandings or
obligations not expressly contained herein or in such contemporaneous agreement
shall be of any force or effect. Neither this Lease, nor any Riders or Exhibits
referred to above may be modified, except in writing signed by both parties. The
Tenant acknowledges that it has not been induced to enter into this Lease by any
representations or warranties not set forth in this Lease. Tenant and its
independent advisors believe that this Lease is the product of all of their
efforts, that it expresses their agreement and therefore they agree that it
should not be interpreted in favor of either Landlord or Tenant or against
either Landlord or Tenant merely because of their efforts in preparing it.

     (e) All obligations of Tenant not fully performed as of the expiration or
earlier termination of the Term of this Lease shall survive the expiration or
earlier termination of the Term, including without limitation, all payment
obligations with respect to Operating Expenses and Taxes and all obligations
concerning the condition of the Demised Premises, pay to Landlord an Additional
Rent Deposit, as estimated by Landlord, of Tenant's obligation hereunder for
Operating Expenses and Taxes. All such amounts shall be used and held by
Landlord for payment of such obligations of Tenant hereunder, with Tenant being
liable for any additional costs therefor upon demand by Landlord, or with an
excess to be returned to Tenant after all such obligations have been determined
and satisfied, as the case may be. Any security deposit held by Landlord shall
be credited against the amount payable by Tenant under this Section. The
vacation of the Building or more into the Building by Tenant shall be governed
by such reasonable rules and regulations adopted by Landlord from time to time,
provided such rules and regulations are uniformly applied to all tenants.

     (f) If any provision of this Lease, or the application thereof to any
person or circumstance, shall be invalid or unenforceable under applicable law,
such event shall not affect, impair or render invalid or unenforceable the
remaining provisions of this Lease nor shall it affect the application of any
provision hereof to other persons or circumstances, and it is also the intention
of the parties to this lease that in lieu of each such provision of this Lease
that is invalid or unenforceable, there be added as a part of this Lease a

                                       30
<PAGE>

provision as similar in terms to such invalid or unenforceable, there be added
as a part of this Lease a provision as similar in terms to such invalid or
unenforceable provision as may be possible and be valid or enforceable.

     (g) Submission and negotiation of this Lease shall not be deemed to be a
reservation of the Demised Premises. Landlord shall not be bound hereby until
its delivery to Tenant of an executed copy hereof signed by Landlord, already
having been signed by Tenant, and until such delivery Landlord reserves the
right to exhibit and lease the Demised Premises to other prospective tenants.
Tenant agrees that its execution of this Lease constitutes a firm offer to enter
the same which may not be withdrawn for a period of thirty (30) days after
delivery to Landlord. Notwithstanding anything contained herein to the contrary
Landlord may withhold delivery of possession of the Demised Premises from Tenant
until such time as Tenant has paid to Landlord the security deposit required
hereunder and the first month's rent as required hereunder, and any other sums
required hereunder.

     (h) If Tenant is a corporation, partnership, limited liability company,
trust or other legal entity, each individual executing this Lease on behalf of
said entity represents and warrants that such entity has been duly formed and
has the power and authority to enter into this lease and that he is duly
authorized to execute and deliver this Lease on behalf of said entity, in
accordance with the organizational and operational documents of said entity, and
that this Lease is valid and binding upon said entity and enforceable in
accordance with its terms. Tenant agrees to furnish to Landlord, promptly upon
demand, a corporate resolution, proof of due authorization by partners, or other
appropriate documentation evidencing the due authorization of Tenant to enter
into this Lease.

     (i) Neither this Lease nor any memorandum of lease or short form lease
shall be recorded by Tenant.

     (j) This Lease does not grant any legal rights to "light and air" outside
the Demised Premises nor any particular view or cityscape visible from the
Demised Premises.

     (k) With respect to any provision of this Lease which provides, in effect,
that Landlord shall not unreasonably withhold or unreasonably delay any consent
or any approval, Tenant, in no event, shall be entitled to make, nor shall
Tenant make, any claim for, and Tenant hereby waives any claim for money
damages; nor shall Tenant claim any money damages by way of setoff, counterclaim
or defense, based upon any claim or assertion by Tenant that Landlord has
unreasonably withheld or unreasonably delayed any consent or approval; but
Tenant's sole remedy shall be an action or proceeding to enforce any such
provision, or for specific performance, injunction or declaratory judgment.

     40. Governing Law. All of the terms, conditions and provisions of this
Lease shall be interpreted in accordance with, and controlled by, the laws of
the State of Maryland (except that the conflicts of laws provisions thereof
shall not apply).

     The parties intending to be bound hereby execute or cause this Lease to be
executed as of the date first above written.

                                      RIDER

     This Rider dated this ______ day of October, 1999 is to that certain lease
agreement of even date herewith ("Lease") by and between XXI OFFICE PLAZA
ASSOCIATES ("Landlord") and TEK DIGITEL, INC., a Maryland corporation
("Tenant").

     R-1. Conflicts. The provisions set forth in this Rider supersede any
contradictory provisions in the Lease and supplements the Lease as the context
requires.

     R-2. Cancellation Option. Tenant shall have the right, notwithstanding the
"Term" of this Lease, to terminate this Lease prior to the expiration of the
Term, such right of termination being effective on as of the last day of the
thirty-sixth (36th) calendar month of the Term hereof ("Cancellation Date"),
subject to and upon satisfaction of the following terms and conditions:

     (a) Tenant provides Landlord with advance notice of its exercise of the
cancellation option at a minimum of six (6) months' prior to the Cancellation
Date accompanied by payment of termination consideration equal to the sum of (i)
Landlord's unamortized leasing costs (assuming a five (5) year amortization
schedule) which costs shall be inclusive of all professional fees, leasing
commissions and tenant improvement costs, incurred in connection with
consummating this lease transaction, (ii) the product of six (6) times the
Monthly Base Rent otherwise due and payable for the thirty-seventh (37th)
calendar month of the Term plus (iii) a reasonable market rate of interest on
the unamortized leasing costs from the Commencement Date to the Cancellation
Date.

     (b) Neither the notice by Tenant of its election to exercise its option to
terminate this Lease, nor the expiration of the six (6) month period following
the notice of election to terminate, nor the payment of the Termination
Consideration shall cure any default of Tenant under this Lease or relieve
Tenant from any of its obligations under this Lease which may have or may accrue
in favor of Landlord prior to the Cancellation Date (including, but not limited
to, the obligations to pay Annual or Monthly Base Rent, or Tax and Operating
Expense Rent Adjustment, other Rent or Adjustments, however described or
occurring, and any other amounts due or to become due to Landlord under this
Lease), or which may accrue upon or by reason of the termination of the Term and
the vacation of (or failure to vacate) the Premises by Tenant; and Tenant
specifically understands and agrees that notwithstanding the termination of this
Lease pursuant to this paragraph, the obligations of Tenant hereunder inclusive
of the Cancellation Date and such rights such as in respect to Tax and Operating
Expense Rent Adjustments as survive the expiration of the Term shall survive
such termination of this Lease.

     (c) On or prior to the Cancellation Date, Tenant shall surrender possession
of the Premises to Landlord in broom clean condition.


     (d) Tenant may only exercise the Cancellation Option, and an exercise
thereof shall only be effective, if at the time of Tenant's exercise of said
option and on the Cancellation Date, this Lease is in full force and effect and
there is no Default by Tenant under this Lease or the giving of notice will
constitute a Default, and (inasmuch as said option is intended only for the
benefit of the original Tenant named in this Lease) the entire Premises are
occupied by the original Tenant named herein and said Tenant has not assigned
this Lease or sublet any portion of the Premises.


     Provided that Tenant shall have complied with all of the requirements of
this Paragraph, upon the Cancellation Date this Lease shall terminate as if the
full Term as otherwise provided bad expired in accordance with the terms of this
Lease, and thereafter Landlord and Tenant shall have no further obligation to
one another, except as provided in Subparagraph (b) above or as may be otherwise
provided in this Lease relative to the expiration of the Term.

     R-3. Communications Equipment License. The Tenant shall be granted a
license to install and operate communications equipment upon the roof of the

                                       32
<PAGE>

Building, pursuant to the terms and covenants and subject to the conditions set
forth in a license agreement to be entered into between Landlord and Tenant
substantially in the form of the agreement attached to this Lease as Exhibit
"C".

     R-4. Extension Option. (a) The Landlord hereby grants to the Tenant an
option to extend the Term of this Lease ("Extension Option") for one (1)
consecutive period of five (5) years commencing immediately after the expiration
of the Term on the same terms, covenants and conditions contained in this Lease,
except as provided herein. Tenant shall exercise the Extension Option on or
before January 1, 2004, time being of the essence.

     (b) Tenant may only exercise its Extension Option, and an exercise thereof
shall only be effective, if at the time of Tenant's exercise and on the
commencement date of the extension period: (i) the Lease is in full force and
effect; (ii) there is no Default by Tenant under any terms, covenants or
conditions of the Lease and no event has occurred which, with the passage of
time or the giving of notice or both would constitute a Default; and (iii)
Tenant has not assigned the Lease or subleased the Premises. If the Extension
Option is not exercised by January 1, 2004, the Extension Option shall thereupon
expire and be of no further force or effect.

     (c) Such Extension Option can only be exercised in respect of the entire
Premises and Tenant shall have no right to exercise the Extension Option as to
less than the entire Premises.

     (d) The Annual Base Rent payable during the extension option period with
respect to the Premises shall be equal to the then "current market rental rate"
(hereinafter defined) for Base Rent per square foot of rentable area, for lease
terms of five (5) year duration commencing on or about the commencement date of
the extension option period, multiplied by the rentable area of the Premises.
For purposes of this Paragraph R-4, the "current market rental rate" shall be
the then prevailing rental rate as determined in good faith by Landlord, for
improved space in the Building or the Development comparable to the Premises in
area, location and degree of improvements (to the extent that quoted rental
rates in the Building or the Development vary with regard to area, location and
degree of improvements). In addition to the Annual Base Rent, additional rent at
the "current market rental rate" shall be payable during the extension option
period, which prevailing rental rate shall include (i) the prevailing provisions
for periodic escalation adjustments to Annual Base Rent; and (iii) the
prevailing provisions in respect of Taxes and Operating Expenses. In no event,
however, shall the Annual Base Rent for the first year of the extension option
period be less than. the adjusted Annual Base Rent payable for the last year of
the original Term with the base rent for subsequent years to be subject to
adjustment as set forth in clause (i) above.

     (e) No additional options to extend the Term shall be construed to be
created by the Extension Option or the exercise thereof and no other
inapplicable provisions such as, but not limited to, any obligation to construct
improvements or make any contribution toward the construction of improvements
shall be construed to govern the extension option period.

     (f) Prior to the commencement date of the extension option period at
Landlord's request Tenant shall enter into a written supplement to the Lease
confirming the terms, covenants and conditions applicable to that extension
option period as determined in accordance herewith, with such revisions to the
rental provisions of this Lease as may be necessary to conform such provisions
to the rental provisions applicable to the extension option period.

     R-5. Landlord's Work. (a) Landlord shall, at its own expense, deliver the
Premises to Tenant with the work completed (the "Work") as depicted on the Space
Plan attached to this Lease as Exhibit "D", all in accordance with Building
Standard specifications.

     (b) Landlord shall, at its own expense, paint the previously painted walls
of the Premises to Building Standard colors. It is expressly understood that
under Building Standard, Tenant shall be limited to one color selection in any
room or area.

     (c) Landlord shall, at its own expense, carpet the Premises to Building
Standard with any carpet selected by Tenant from Landlord's Building Standard
carpets. It is expressly understood that the carpeting shall be deemed to be a

                                       33
<PAGE>

permanent leasehold improvement and shall, accordingly, not be removed from the
Premises upon the termination or expiration of the Lease.

     (d) Landlord has not agreed to perform any other work in the Premises, and
all other work necessary to complete the Premises shall be done at Tenant's sole
cost and expense, in accordance with the terms and conditions of the Lease. If
at Tenant's request, Landlord agrees to do any work in connection with the
completion of the Premises, such other work shall be done at Tenant's sole cost
and expense, as an extra, in accordance with plans, drawings, and specifications
furnished by Tenant, subject to the approval of Landlord. Prior to commencing
any additional work, Landlord shall submit to Tenant written estimates of the
cost thereof and if Tenant shall fail to approve such estimates within seven (7)
days from the receipt thereof, the same shall be deemed to be disapproved and
Landlord shall not be authorized to proceed with such additional work and Tenant
shall be deemed to have abandoned its request therefor. If the estimates are
approved and Landlord proceeds with such additional work, Tenant shall pay
Landlord the cost thereof (including direct costs for rubbish removal, hoisting,
permits, and similar items) plus fifteen percent (15%) of said cost for
Landlord's supervision and construction management services, upon being billed
therefore at any time and from time to time.

     R-6. Parking. Landlord hereby provides to Tenant a license to use during
the Term of this Lease and renewal thereof at no daily or monthly charge
twenty-four (24) non-exclusive and unreserved spaces in the parking garage
facility on a first come, first served basis. Landlord, at its discretion, (i)
may designate the specific space or areas where each vehicle shall be parked;
and (ii) may change such designated areas from time to time. Upon written
request by Landlord, Tenant shall furnish within thirty (30) days to Landlord
the license numbers of all vehicles of Tenant's employees, which Tenant
anticipates will use the parking garage facility. The foregoing license is
subject to any restrictions of record. All employees of Tenant are to park in
the parking garage facility with the front outdoor parking area reserved for
visitors to the Development only.

     R-7. Access to Development. The Tenant shall have access to the garage
parking facility and to its Premises in the Development on a twenty-four (24)
hour, seven (7) day per week basis via electric card access system.

Landlord, of which Tenant has been given notice, for the care and use of the
Building and Development and their facilities and approaches. Landlord's current
Rules and Regulations are as follows:

     (a)  Any sign installed in the Demised Premises or anywhere within the
          Development shall be installed by Landlord at Tenant's cost and in
          such manner, character and style as Landlord may approve in writing.
          No sign, advertisement or notice shall be inscribe, painted or affixed

      (b) Tenant shall not advertise the business, profession or

          shall never use any picture or likeness of the Building in any
          circulars, notices, advertisements or correspondence without the
          Landlord's express consent in writing. Landlord shall have the right
          to prohibit any advertisement of any tenant in which the Landlord's
          opinion tends to impair the reputation of the Development or its
          desirability as a Development for offices or for financial, insurance

          Building. No freight, furniture or other bulky matter of any
          description will be received into the Building or carried in the

     (e)  Tenant shall not make or permit any noise or odor that is
          objectionable to other occupants of the Building to emanate from the
          Demised Premises, and shall not create or maintain a nuisance thereon,

          aerial wires or other equipment inside or outside the Building,
          without, in each and every instance, prior approval in writing by the
          Landlord. The use thereof, if permitted, shall be subject to control

          annoyed by vibrations, noise, electrical interference or other
          disturbance.

          the Landlord shall be made. If more than two (2) keys for one (1) lock
          are desired by Tenant, Landlord may provide the same upon payment by
          Tenant. Upon termination of this Lease or of the Tenant's possession,
          Tenant shall surrender all keys of the Demised Premises and shall make
          known to Landlord the explanation of all combination locks on safes,
          cabinets, vaults and doors leading to the corridors or main halls


                                       36
<PAGE>
          shall be kept closed during business hours except as they may be used
          for ingress and egress.

          therein.

     (j)  If Tenant desires telegraphic, telephonic, burglar alarm or signal
          service, Landlord will, upon request, direct where and how connections
          and all wiring for such service shall be introduced and run. Without
          such directions, no boring, cutting or installation or wires or cables
          is permitted.

          Premises, or carry on any mechanical business therein, or use the
          Demised Premises for housing accommodations or lodging or sleeping
          purposes, or do any cooking therein or install or permit the

          benzene, or any explosive or other articles hazardous to persons or
          property.

     (m)  Tenant shall not place or allow anything to be placed against or near
          the glass of partitions, doors or windows of the Demised Premises

     (n)  Tenant shall not install in the Demised Premises any equipment which
          uses a substantial amount of electricity without the advance written
          consent of the Landlord. Tenant shall ascertain from the Landlord the
          maximum amount of electrical current which can safely be used in the
          Demised Premises, taking into account the capability of the electric
          wiring in the Building and shall not use more than such safe capacity.

          instance, do any cooking, baking, heating, preparation, serving or

                                LICENSE AGREEMENT

     This Agreement, made and entered into this ______ day of October, 1999, by
and between XXI OFFICE PLAZA ASSOCIATES (the "Licensor") and TEK DIGITEL, INC.,
a Maryland corporation (the "Licensee").

     1. GRANT AND PURPOSE: Commencing on Licensor hereby grants to Licensee, and
Licensee hereby accepts, a license to (a) install, maintain and operate for the
term hereof, a satellite dish antenna more fully described on Appendix "A"
attached hereto ("Antenna") having the size and weight specifications and
frequency ranges described on Appendix "A" attached hereto at the location and
mounted as described on Appendix "B" attached hereto, at the building known as
Century XXI Office Complex, ("Building"), subject to all governmental laws,
rules and regulations, including but not limited to local zoning ordinances and
restrictions of record, in accordance with the following terms, covenants and
conditions.

     2. GENERAL USE RESTRICTIONS. (A) Licensee may install, maintain, or use the
Antenna in accordance with this License provided: (i) an acceptable amount of
spare space for additional facilities shall be maintained for existing and
future occupants, suppliers or utility companies of the Building, as determined
in Licensor's reasonable opinion, (ii) if the use of the Antenna or its related
equipment at any time may create an electromagnetic field exceeding normal
insulation ratings or cause radiation higher than normal, the Antenna facilities
shall be appropriately insulated to prevent such excessive electromagnetic
fields or radiation, and (iii) Licensee's use does not unreasonably interfere
with the use of similar equipment used by other occupants in the Building or the
use of the roof area by Licensor for any purpose whatsoever. Licensor reserves
the right to require that Licensee relocate or remove the Antenna upon any
violation or the occurrence of these provisions, or upon any violation of any
governmental laws, rules or regulations or restrictions of record or if the
Antenna becomes a dangerous or potentially dangerous condition, if Licensee
fails to correct such condition within three (3) days after written notice from
Licensor to Licensee.

     (B) Licensee shall not, without the prior written consent of Licensor in
each instance, grant to any third party a security interest or lien in or on the
Antenna, and any such security interest or lien granted without Licensor's
written consent shall be null and void. Licensor does not warrant that the
Licensee's use or operation of the Antenna will be free from the following
(collectively called "Facilities Problems"): (x) any eavesdropping or
wire-tapping by unauthorized parties, (y) any failure of the Antenna to satisfy
Licensee's requirements, or (z) any shortages, failures, variations,
interruptions, disconnections, loss or damage caused by the installation,
maintenance, replacement, use or removal of communication facilities by or for
other tenants or occupants at the Building, by any failure of the environmental
conditions or the power supply for the Building to conform to any requirements
for the Antenna or any associated equipment, or any other problems associated
with the Antenna by any other cause. Under no circumstances shall any Facilities
Problems, render Licensor or Landlord liable to Licensee for damages by reason
of loss of profits, business interruption or other consequential damage, or
relieve Licensee from performance of Licensee's obligations under this License
or the "Lease" (as herein defined).

     3. TERM: The term of this License shall expire simultaneously with the
expiration or earlier termination of the lease agreement (the "Lease") dated
October ______, 1999 by and between the Licensor, as the landlord and Licensee,
as the tenant, for premises known as Suite 201 located at the 20030 Century
Boulevard, Germantown, Maryland (the "Premises") unless sooner terminated as
provided herein.

     4. PERMITS AND LICENSES: Licensee, at its sole risk, effort and expense,
will install, maintain and operate the Antenna in compliance with all laws,
ordinances or regulations, federal, state or local, applicable thereto
(collectively "Laws"), and secure all licenses or permits which are necessary in
connection with this License or the Antenna. Licensee will give Licensor timely
notice of any requirements, whether governmental or otherwise, with which
Licensor must comply pertaining to the Antenna, and Licensee will bear any cost
attendant to such compliance. Licensee will have the ongoing duty to assure that
the operation of the Antenna continues to be in compliance with all Laws and
that all required permits and licenses are maintained and kept current. Should
the necessary governmental or other approvals, licenses or permits not be
granted or after granted be withdrawn, canceled or terminated, then this License

                                       38
<PAGE>

will immediately terminate, and both parties will be relieved of any further
obligation to the other (except that Licensee's obligations under paragraphs 8
and 10 hereof shall survive any such termination).

     5. TAXES: Licensor hereby acknowledges that the Antenna, irrespective of
the fact that the same may be affixed or attached to the premises and otherwise
by operation of law would become or could be deemed to become a part of the
premises, shall not be nor be deemed to be a part of the premises and shall at
all times remain the sole and exclusive personal property of the Licensee.
Licensee will pay all personal property, excise or other taxes, assessments and
license fees relating to the operation of the Antenna.

     6. INSTALLATION: The parties anticipate that the installation of the
Antenna at the location agreed upon may require alterations or additions and
utility connections (the "Installation"). Licensee will install the Antenna in a
good and workmanlike manner under the supervision of Licensor and pursuant to
plans and specifications approved in advance by Licensor in writing. Licensee
shall not make any alterations or additions to the Antenna without the prior
written consent of Licensor, which consent shall not be unreasonably withheld,
conditioned or delayed. In connection with the Installation, the Licensee shall
secure appropriate final lien waivers executed and notarized by all parties
performing services or providing materials.

     7. MAINTENANCE: Licensee will provide complete maintenance and repair
services (i) for the Antenna, pertaining to appearance, cleaning, parts and
labor (whether or not the defects are covered by manufacturer's warranties),
with the objective of keeping the Antenna in good operating order, condition and
repair; and (ii) for the portions of the Building and roof which Licensee
utilized in respect of the Antenna, pertaining to the condition of the roof and
building structure, with the Licensee being responsible for all damages and
losses resulting from this License or from the acts or omissions of the
Licensee, including but not limited to the invalidation of any roof warranty,
with the objective of keeping the Building structure and roof in good condition
and repair (collectively the "Maintenance") all of which will be performed under
the supervision of Licensor. Licensor shall have the right at all times, and
from time to time, to inspect the Antenna and its location for any purpose
whatsoever. If Licensee ceases to perform its Maintenance obligations in
accordance herewith, and such failure continues for more than ten (10) days
after Licensor's written notice to Licensee, then Licensor may upon reasonable
notice terminate this License, and Licensee shall within fifteen (15) days of
such termination remove the Antenna and perform its Removal and Restoration
obligations outlined in paragraph 8 hereof, immediately after such event. The
foregoing ten (10) day grace period will be extended to thirty (30) days to the
extent the failure cannot reasonably be cured by Licensee within such ten (10)
day period and Licensee has commenced to cure and is diligently prosecuting the
cure to completion during such ten (10) day grace period. Upon the foregoing
termination, the Licensee's obligation to pay the monthly license fee shall
likewise terminate.

     8. REMOVAL: Upon the expiration or earlier termination of the License,
Licensee shall remove the Antenna and all improvements from the premises (the
"Removal") and restore the location to its appearance and condition existing
immediately before the original installation of the Antenna (the "Restoration").
The Removal and Restoration must be performed under the supervision of Licensor
unless otherwise specified herein completed within thirty (30) days after the
expiration or earlier termination of the License.

     9. SUBCONTRACTING AND RELATIONSHIP BETWEEN THE PARTIES: Licensee may
subcontract all or any part of the Installation, Maintenance, Removal, or
Restoration of the Antenna. Should any part of Licensee's responsibilities
hereunder be subcontracted, such subcontractor shall be Licensee's sole
responsibility and shall comply with all the terms, covenants and conditions
herein as if said subcontractor were included in the term "Licensee". Licensee
and its subcontractors shall at all times be independent contractors, and it is
not the intent of Licensee or Licensor to create any type of lease, employment,
agency, partnership or joint venture relationship.

                                   EXHIBIT "D"

                                   WORKLETTER

     This is the Workletter referred to in the lease to which this Exhibit "D"
is attached (the "Lease") wherein the Tenant is leasing certain office space
(the "Demised Premises") from the Landlord at the property known as XXI Century
Office Plaza, Germantown, Maryland (the "Development"). Capitalized terms used
herein, unless otherwise defined in this Workletter, shall have the respective
meanings assigned to them in the Lease.

     1. Work. Landlord, at Landlord's sole cost and expense, shall provide the
construction material, hardware and equipment and the labor to construct and
install improvements (the "Work") to the Demised Premises in accordance with a
Construction Plan to be prepared by Landlord in a manner consistent with the
Space Plan attached hereto as Attachment "I". Landlord shall cause the
Construction Plan to be prepared as soon as practicable following the receipt of
such Space Plan and shall promptly thereafter deliver a copy of the Construction
Plan to Tenant. Tenant shall have three (3) business days to approve the
Construction Plan and returning same to Landlord. Once the Construction Plan is
approved by Tenant, should a conflict arise between the provisions of this
Workletter and the Construction Plan, the Construction Plan shall govern and
control. Subject to the provisions of this Workletter, Landlord shall proceed
diligently to cause the Work to be substantially completed in accordance with
the terms and conditions of the Lease.

     Landlord agrees to pay all fees in connection with the Construction Plan
(the "Plans"), to a maximum allowance of $6.00 per square foot.

     2. Additional Work. If Tenant wishes Landlord, prior to the commencement of
the Term, to employ labor and to use items of material, hardware, equipment or
decorating that exceed Landlord's obligation hereunder as limited to the term
"Work" (such excess items are herein referred to collectively as "Additional
Work"), Tenant shall, at its expense, cause drawings and specifications
("Additional Plans") for the Additional Work to be completed and submit such
Additional Plans to the Landlord for its approval. Landlord shall not withhold
its approval unreasonably if the Additional Work does not affect the structure
or safety or the exterior appearance of the Development or the heating
ventilating, air conditioning, plumbing or other mechanical systems of the
Development. If Landlord approves the Additional Work as reflected in the
Additional Plans, Landlord shall obtain and submit to Tenant estimates of the
cost of the Additional Work. The cost of such Additional Work shall include the
direct costs thereof, plus general conditions (including rubbish removal,
hoisting, permits, field supervision and the like) plus the contractor's charges
for overhead and fees, together with ten percent (10% of all such costs for
overhead and construction management services, which fee shall be paid to
Landlord, or its agent, as Landlord shall direct. Landlord shall not be
obligated to proceed with such Additional Work until the cost set forth in such
estimate is paid by Tenant to Landlord for deposit in Landlord's trust account
for payment of the Additional Work as work progresses. Any deficit shall be paid
to Landlord upon completion of such Additional Work and within seven (7) days
after Landlord shall have furnished Tenant with bills for the complete costs
thereof.

     Any Additional Work or alterations to the Demised Premises desired by
Tenant after the commencement of the Term shall be subject to the provisions of
Section 11 of the Lease.

     3. Delays in Tenant Work. Notwithstanding the date provided in the lease
for the commencement of the Term thereof to the contrary, Tenant's obligations
to pay Rent thereunder shall not commence until Landlord shall have
substantially completed all Work to be performed by Landlord, as set forth in
Paragraph 1 hereof; provided, however, if Landlord shall be delayed in
substantially completing the work for any reason set forth in the following
Subsections (a) through (d) of this Section 3, then the Term of the Lease shall
commence on the date otherwise provided therein and the payment of Rent
thereunder shall not be affected or deferred on account of such delay:

          (a) Tenant's failure to timely furnish any information required for
     the preparation of the Plans as and when requested by Landlord; or

                                       43

          (b) Any reason relating to the request by Tenant for, or the
     completion by landlord of, the Additional Work; or

          (c) Tenant's changes in the Work or the Plans after initial approval
     by Landlord and Tenant (notwithstanding Landlord's further approval of any
     such changes); or

          (d) Any other act, omission or delay by Tenant, its agencies,
     contractors interior space planner (due to actions or inactions of Tenant)
     or persons employed by any of such persons delaying the substantial
     completion of the Work, including actions by or on behalf of Tenant
     pursuant to Paragraph 4 hereof.

     4. Access by Tenant Prior to Commencement of Term. Landlord will permit
Tenant and Tenant's agents, suppliers, contractors and workmen to enter the
Demised Premises prior to the commencement of the Term to enable Tenant to do
such things as may be required by Tenant to make the Demised Premises ready for
Tenant's occupancy, provided that Tenant and its agents, contractors, workmen
and suppliers and their activities in the Demised Premises and Development will
not interfere with or delay the completion of the Work or Additional Work to be
done by Landlord and will not interfere with other activities of Landlord or
occupants of the Development, and only upon prior notice to Landlord. Such
notice must specifcy the name of the licensed contractor, contact information,
insurance compliance and certificates of insurance as per the Lease Agreement,
and days and times of access desired. The Landlord shall have the right, on
notice to Tenant, to cause Tenant or any such agent, contractor, workman or
supplier to leave the Demised Premises and the Development if Landlord
determines that any such interference or delay has been or may be caused. Tenant
agrees that any such entry into the Demised Premises shall be at Tenant's own
risk and Landlord shall not be liable in any way for any injury, loss or damage,
which may occur to any of Tenant's property or Tenant's installations made in
the Demised Premises and Tenant agrees to protect, defend, indemnify and save
harmless Landlord, its partners and their respective agents from all
liabilities, costs, damages, fees and expenses arising out of or connected with
the activities of Tenant or its agents, contractors, suppliers or workmen in or
about the Demised Premises or Development. In addition, prior to the initial
entry to the Development or the Demised Premises by Tenant and by each
contractor or subcontractor for Tenant, Tenant shall furnish Landlord with
policies of insurance covering Landlord as an insured party with such coverages
and such amounts as Landlord may then require in order to insure Landlord
against liability for injury or death or damage to property of Landlord or its
tenants by reason of such entry and any activity or work carried on, in or about
the Development or the Demised Premises.

     5. Miscellaneous. (a) The Work shall be done by Landlord, or its designees,
contractors or subcontractors, in accordance with the terms, conditions and
provisions herein contained.

     (b) Except as herein expressly set forth or in the Lease, landlord has no
agreement with Tenant and has no obligation to do any other work with respect to
the Demised Premises. Any other work in the Demised Premises which Tenant may be
permitted by Landlord to perform prior to commencement of the Term shall be done
at Tenant's sole cost and expense and in accordance with the terms and
conditions of the Lease, including, without limitation, Section 11, the terms
and provisions of Paragraph 4 of this Workletter and such other requirements as
Landlord deems necessary or desirable. Any additional work or alterations to the
Demised Premises desired by Tenant after the commencement of the Term shall be
subject to the provisions of Section 11 of the Lease.

     (c) Time is of the essence under this Workletter.

     (d) Any person signing this Workletter on behalf of the Landlord or Tenant
warrants and represents he has authority to do so.

     (e) This Workletter shall not be deemed applicable to any additional office
space added to the original Demised Premises at any time or from time to time,
whether by any options under the Lease or otherwise, or to any portion of the
original Demised Premises or any additions thereto in the event of a renewal or
extension of the original Term of this Lease, whether by any options under the
Lease or otherwise, unless expressly so provided in the Lease or any amendment
or supplement thereto.

     (f) With respect to any amounts owed by Tenant hereunder and not paid when
