[The provisions of the Basic Lease Information are hereby incorporated into and
made a part of this Lease].

         THIS LEASE AGREEMENT (this "Lease") is made and entered into as of the
Lease Execution Date by and between

                           CRESCENT RESOURCES, INC.,
                           a South Carolina corporation,

hereinafter called "Landlord"; and

                           American Aircarriers Support, Inc.
                           a ____________________________________ corporation,

hereinafter called "Tenant";



                              W I T N E S S E T H:



         In consideration of the mutual covenants and agreements contained
herein, the parties agree for themselves, their successors, and assigns, as
follows:

         1. Description of Premises; Purpose. Landlord hereby leases to Tenant,
and Tenant hereby accepts and rents from Landlord, the Premises located in the
Building (as those terms are defined in the Basic Lease Information), together
with the nonexclusive right to use all parking areas, driveways, sidewalks and
other common facilities furnished by Landlord from time to time in the Building
or on the Land for the common use of tenants in the Building. The Premises are
designated on the building plan attached hereto as Exhibit B. Tenant shall use
the Premises for its Tenant Operations only and for no other purpose.

         2. Lease Term. The term of this Lease (the "Lease Term") shall commence
on the Lease Execution Date and shall end at midnight on the Expiration Date,
unless extended by the exercise of the following option to renew. Tenant is
hereby granted an option to renew and extend the Lease Term for one (1)
additional period of five (5) years (the "Renewal Term") commencing on the
initial Expiration Date. Tenant may exercise its option to renew only if it is
not in default hereunder and only by giving Landlord written notice of such
exercise not less than one hundred eighty (180) days prior to the initial
Expiration Date. The foregoing renewal rights may be execised only by the
original Tenant and shall not inure to the benefit of any assignee, subtenant or
other transferee of the original Tenant. All of the terms and conditions hereof
shall apply during the Renewal Term except that (i) Tenant shall have no further
right to renew this Lease beyond the Renewal Term and (ii) Landlord shall have
no obligation to perform any work or improvements in or in respect of the
Premises.

         3. Construction and Acceptance of Premises.

         (a) Landlord shall proceed to construct improvements upon the Premises
in compliance with the "Description of Landlord's Work" in Exhibit C attached
hereto, with such minor variations as Landlord may deem advisable, and shall
tender the Premises to Tenant. The Premises shall be deemed to be "Ready for
Occupancy" when Landlord has substantially completed Landlord's Work, as
described in Exhibit C and obtained a Certificate of Occupancy from the
appropriate governmental authority. If the Premises are not Ready for Occupancy
prior to the Occupancy Date that is set forth in the Basic Lease Information,
Landlord shall not be deemed to be in default hereunder or otherwise liable in
damages to Tenant, nor shall the Lease Term be affected (other than as set forth
in Paragraph 3(c) herein), except that if for any reason (other than delays
caused by Tenant and Tenant's agents, employees, contractors, subcontractors or
licensees (collectively, "Tenant Delay Factors"), including, without limitation,
change orders requested by Tenant relative to the Description of Landlord's
Work) the Premises are not Ready for Occupancy within six (6) months following
the Occupancy Date that is set forth in the Basic Lease Information (provided
such six-(6) month period shall be extended relative to any delays 


4
<PAGE>   5

in getting the Premises Ready for Occupancy resulting from Force Majeure
Matters, as defined herein), Tenant may, at its option, terminate this Lease by
written notice to Landlord delivered within thirty (30) days following the
expiration of such six-(6) month period, in which event neither party shall have
any further liabilities or obligations hereunder, except Landlord shall repay to
Tenant any prepaid rent (including the Advance Rental Payment, as defined
herein) or Security Deposit (as defined herein) and all indemnification
obligations herein shall survive such termination. Time is of the essence
relative to Tenant's right to terminate this Lease pursuant to this Paragraph
3(a). When the Premises are Ready for Occupancy, Tenant agrees to accept
possession thereof By accepting possession of the Premises, Tenant shall be
deemed to have accepted the same and to have acknowledged that the same fully
comply with Landlord's covenants and obligations hereunder. Tenant further
agrees that, if requested by Landlord, Tenant will furnish Landlord with a
written statement that Tenant has accepted the Premises and that Landlord has
fully complied with Landlord's covenants and obligations hereunder.

         (b) If any Tenant Work is specified in Exhibit C, Tenant agrees to
proceed with due diligence to perform the work described under "Description of
Tenant's Work" in Exhibit C, all of such work to be performed in a good and
workmanlike manner, using new materials, in accordance with plans and
specifications approved by Landlord and in compliance with Exhibit C, and to
install Tenant's fixtures, furniture and equipment in the Premises. Any Tenant
Work or any other work in or with respect to the Premises performed by Tenant in
the future causing venting, opening, sealing, waterproofing or any altering of
the roof of the Building shall be performed by Landlord's roofing contractor at
Tenant's expense. Tenant shall provide Landlord with a certificate from
Landlord's roofing contractor that all such work causing venting, opening,
sealing, waterproofing or in any way altering the roof of the Building has been
performed properly. Tenant hereby holds Landlord harmless from any damage to the
Premises resulting, directly or indirectly, from Tenant's venting, opening,
sealing, waterproofing or in any other way altering the roof of the Building
unless such a certificate from Landlord's roofing contractor was delivered to
Landlord contemporaneously with the completion of such work. In the event of any
dispute as to work performed or required to be performed by Landlord or Tenant,
the certificate of Landlord's architect or engineer shall be conclusive.

         (c) In the event the Premises shall be Ready for Occupancy (as defined
in Paragraph 3(a) herein) prior to the Occupancy Date that is set forth in the
Basic Lease Information, the Occupancy Date shall be the earlier of (i) the date
that is set forth as the Occupancy Date in the Basic Lease Information or (ii)
the date that Tenant occupies the Premises. In the event of a delay in the
completion of Landlord's Work beyond the Occupancy Date that is set forth in the
Basic Lease Information (as contemplated in Paragraph 3(a) herein), the term
"Occupancy Date" herein shall automatically be modified to become the actual
date the Premises shall become Ready for Occupancy and the Expiration Date shall
automatically be modified on a consistent basis (i.e., to afford the full Lease
Term, as defined in the Basic Lease Information). Provided, however, and
notwithstanding the foregoing terms and provisions to the contrary, if and to
the extent the Premises are not Ready for Occupancy on or before the Occupancy
Date set forth in the Basic Lease Information as a result of one or more Tenant
Delay Factors, there shall be no adjustment in the Occupancy Date and the
Expiration Date that are set forth in the Basic Lease Information.

         4. Annual Rental. From and after January 1, 1999, and during the full
Lease Term (as the same may be extended), Tenant shall pay to Landlord, without
notice, demand, reduction, setoff or any defense, a total annual rental (the
"Annual Rental") consisting of the sum total of the Minimum Rental and Tenant's
Proportionate Share (as said terms are defined herein) of taxes, insurance
premiums and common area maintenance costs (provided, however, as set forth in
the Basic Lease Information, payment of Minimum Rental shall not commence until
the Rent Commencement Date).

         (a) Minimum Rental. For the period from the Rent Commencement Date
through the Expiration Date, as the same may be extended pursuant to Paragraph
2, Tenant shall pay a minimum rental (the "Minimum Rental") at the annual rates
set forth below, in equal monthly installments, in advance on the Rent
Commencement Date and on the first day of each month thereafter during the
remainder of the Lease Term. Minimum Rental for any parital calendar month shall
be prorated on a per diem basis.

Hundred Forty-Seven Thousand Thirty-Five and 95/00 Dollars ($347,035.95), in

                  (iii) From January 1, 2003, through December 31, 2003, Tenant

Thousand Forty-Two and 36/100 Dollars ($375,042.36), in equal monthly
installments of Thirty-One Thousand Two Hundred Fifty-Three and 53/100 Dollars
($31,253.53) each.

                  (iv) During the first year of the Renewal Term (from January
1, 2004, through December 31, 2004), if any, Tenant shall pay Minimum Rental at
the annual rate of Three Hundred Eighty-Two Thousand Three Hundred Forty-Eight
and 38/100 Dollars ($382,348.38), in equal monthly installments of Thirty-One
Thousand Eight Hundred Sixty-Two and 37/100 Dollars ($31,862.37) each.

                  (v) On January 1, 2005, and on January 1 of each successive
calendar year during the Renewal Term, if any, the Minimum Rental shall be
increased by two percent (2%) of the Minimum Rental payable during the next
preceding calendar year.

         (b) [Intentionally deleted].

         (c) Tenant's Proportionate Share. "Tenant's Proportionate Share" of the
taxes, of the insurance premiums and of common area maintenance costs (including
any assessment by a property owner's association), as described herein, shall be
determined by multiplying each such amount by a fraction, the numerator of which
is the total square footage of space in the Premises and the denominator of
which is the total square footage of space in the Building.

                  (1) Tenant's Proportionate Share of Taxes. Tenant shall pay an
         amount equal to Tenant's Proportionate Share of any ad valorem taxes
         (or any tax hereafter imposed in lieu thereof) payable for the Building
         relative to the Lease Term. Tenant's Proportionate Share of taxes shall
         be paid as provided in Paragraph 4(d) herein. Anything contained herein
         to the contrary notwithstanding, any increase in ad valorem taxes on
         the Premises as a result of alterations, additions or improvements made
         by, for or on account of Tenant shall be reimbursed entirely by Tenant
         to Landlord (as additional rent hereunder) within thirty (30) days
         after Tenant's receipt of written demand therefor.

                  (2) Tenant's Proportionate Share of Insurance Premiums. Tenant
         shall pay an amount equal to Tenant's Proportionate Share of any amount
         of premiums charged for fire and extended coverage and liability
         insurance, together with all endorsements thereto, carried by Landlord
         on the Building relative to the Lease Term. Tenant's Proportionate
         Share of insurance premiums shall be paid as provided in Paragraph 4(d)
         herein.

                  (3) Tenant's Proportionate Share of Common Area Maintenance
         Costs. Tenant shall pay an amount equal to Tenant's Proportionate Share
         of the costs of maintaining the Building's common areas (as designated
         from time to time by Landlord for the common use of tenants of the
         Building) relative to the Lease Term. Common area maintenance costs
         shall include, but are not limited to, the cost of grass mowing, shrub
         care and general landscaping (including irrigation); the cost of
         repairing, replacing and maintaining parking areas, driveways,
         sidewalks, exterior lighting, common plumbing, common advertising signs
         and other facilities operated with respect to the Building; the cost of
         providing security for the Building and the Land; the cost of providing
         fire alarm monitoring for the Building; and property management fees
         and expenses. Additionally, if a property owner's association is
         established for the maintenance of the common areas 


6
<PAGE>   7

         of the Center, any property owner's association charges allocated to
         the Land and the Building shall be included in the maintenance costs
         for the Land and the Building, and Tenant shall pay Tenant's
         Proportionate Share thereof. Tenant's Proportionate Share of common
         area maintenance costs shall be paid as provided in Paragraph 4(d)
         herein. Landlord shall use good faith efforts to keep the operating and
         maintenance costs in line with costs for other similarly situated first
         class centers. Tenant, at its expense, shall provide its own garbage
         collection, recycling and disposal.

         (d) Payment of Tenant's Proportionate Share. The estimated amounts of
Tenant's Proportionate Share for taxes, insurance premiums and common area
maintenance costs for the calendar year in which the Rent Commencement Date
(i.e., the Rent Commencement Date that is set forth in the Basic Lease
Information) falls are set forth in the Basic Lease Information. For each
succeeding calendar year during the Lease Term, Landlord shall submit an
estimate of Tenant's Proportionate Share for taxes, insurance premiums and
common area maintenance costs on or before April 1 of each such succeeding
calendar year. If an estimate of Tenant's Proportionate Share of expenses for
any calendar year during the Lease Term has not been submitted on or before the
first day of any month in such calendar year, Tenant shall pay Tenant's
Proportionate Share for such month(s) at the estimated rate for the previous
calendar year, and such payment(s) shall be adjusted effective as of January 1
of such calendar year at such time as the estimate for such calendar year is
submitted, at which time the deficiency or overage (as the case may be) in the
estimated payments for the preceding months in such calendar year also shall be
collected or credited (as the case may be). Landlord shall charge, and Tenant
shall pay, the estimated Tenant's Proportionate Share of expenses on a monthly
basis or on some other periodic basis established by Landlord, payable in
advance and subject to adjustment after the end of the respective calendar year
on the basis of the actual costs incurred for such calendar year. Tenant's
Proportionate Share of estimated taxes, insurance premiums and common area
maintenance costs shall be paid in a like manner, with the monthly rental
installments being adjusted accordingly. In the event such costs actually
decrease for any such calendar year, Landlord shall reimburse Tenant for any
overage paid and the monthly rental installments for the next period shall be
reduced accordingly (but in no event below the then-current Minimum Rental).
Upon the Expiration Date of this Lease, Landlord may elect to either (i) require
Tenant to pay any unpaid estimated Tenant's Proportionate Share within thirty
(30) days after the Expiration Date, which estimate shall be made by Landlord
based upon actual and estimated costs for such year, or (ii) elect to withhold
Tenant's Security Deposit until the exact amount of Tenant's Proportionate Share
shall have been determined and paid, after which Landlord shall return any
excess Security Deposit to Tenant.

         (e) Late Charge. If Tenant should fail to pay to Landlord when due any
installment of Annual Rental or other sum to be paid hereunder, Tenant shall pay
Landlord on demand a late charge of four percent (4%) of the amount due. Failure
to pay such late charge upon demand therefor shall be an Event of Default (as
defined herein) hereunder. Provision for such late charge shall be in addition
to all other rights and remedies available to Landlord hereunder or at law or in
equity and shall not be construed as liquidated damages or as limiting
Landlord's remedies in any manner, and such late charge shall accrue
automatically, regardless of whether Landlord shall have given Tenant written
notice of any such delay in payment.

         5. Alterations and Improvements by Tenant. Any structural changes or
other material alterations, additions, or improvements made to the Premises by
Tenant shall be subject to the prior written consent of Landlord and shall be at
the sole cost and expense of Tenant. All such alterations, additions or
improvements shall be constructed in a good and workmanlike manner, using new
materials, in accordance with plans and specifications approved by Landlord and
in compliance with the terms of Paragraph 3(b) herein and all Applicable Laws.
As used herein, "Applicable Laws" shall mean all laws, ordinances (including
Fire and Building Codes), regulations, orders, interpretations and zoning
requirements of any governmental authority, agency or other public or private
regulatory authority (including insurance underwriters or rating bureaus) which
may be in effect from time to time and relating to the Tenant Operations, the
Premises or Tenant's business conducted therein. Additionally, Tenant covenants
and agrees that no improvements, changes, alterations, additions, maintenance or
repairs shall be made by Tenant to the Premises which might impair the
structural soundness of the Building, which might result in 


7
<PAGE>   8

an overload of the weight capacity of floors in the Building, which might result
in an overload of capacity of electric lines serving the Building, or which
might interfere with electric or electronic equipment in the Building or on any
adjacent or nearby property. Upon the expiration or earlier termination of this
Lease, all alterations, additions or improvements, including, without
limitation, all walls, railings, carpeting, floor and wall coverings and other
permanent real estate fixtures (excluding, however, Tenant's trade fixtures and
equipment, as described in Paragraph 11 herein) made by, for, or at the
direction of Tenant, and upon the election of Landlord, shall either: (i) become
the property of Landlord and remain upon the Premises or (ii) be removed from
the Premises by Tenant, at Tenant's sole cost and expense.

         6. Use of Premises. Tenant shall use the Premises only for the Tenant
Operations and for no other purpose and shall comply with all Applicable Laws in
connection with the use of the Premises. Tenant shall be responsible for any and
all costs and expenses associated with Tenant's compliance with all Applicable
Laws, including the cost of altering the Premises to comply with Applicable Laws
(including changes therein from time to time). Without limiting the generality
of the foregoing, Tenant shall be responsible, at Tenant's expense, for all
costs of complying with the requirements of the Americans With Disabilities Act
(as amended) (the "ADA"), including costs for alterations, (i) relative to the
Premises and, (ii) to the extent such compliance is required as a result of the
specific use made by Tenant of the Premises, relative to the exterior and common
areas and facilities of the Building. Landlord shall be responsible for
complying with the requirements of the ADA relative to the exterior and common
areas and facilities of the Building in all instances other than where such
compliance is required as a result of the specific use made of space in the
Building by any tenant in the Building. Additionally, Tenant covenants and
agrees that nothing shall be done or kept in the Premises which might result in
an overload of the weight capacity of floors in the Building, which might result
in an overload of capacity of electric lines serving the Building, or which
might interfere with electric or electronic equipment in the Building or on any
adjacent or nearby property. Tenant shall not do any act or follow any practice
relating to the Premises which shall constitute a nuisance or detract in any way
from the reputation of the Center as a first class real estate development.
Tenant's duties in this regard shall include allowing no noxious or offensive
odors, fumes, gases, smoke, dust, steam or vapors, or any loud or disturbing
noise or vibrations to originate in or emit from the Premises. If, within thirty
(30) days of demand therefor by Landlord, Tenant fails, at its expense, to make
any alterations required to be made by Tenant pursuant to this paragraph, then
Landlord shall have the right to make such alterations (including any entry
required in the Premises to make such alterations), and Tenant shall pay to
Landlord (as additional rent hereunder) all costs and expenses incurred by
Landlord relative to such alterations; and such additional rent shall be paid by
Tenant to Landlord within thirty (30) days after demand therefor by Landlord.
Additionally, Tenant shall save Landlord harmless from any penalties, fines,
costs, expenses or damages resulting from Tenant's failure to comply with the
terms and requirements of this paragraph.

         7. Taxes. Tenant shall pay in a timely manner and prior to delinquency
any taxes or assessments of any nature imposed or assessed upon its trade
fixtures, equipment, machinery, inventory, merchandise or other personal
property located on the Premises and owned by or in the custody of Tenant.
Landlord shall pay all ad valorem property taxes which are now or hereafter
assessed upon the Center, the Building and the Premises, except as otherwise
expressly provided in this Lease.

         8. Fire and Extended Coverage Insurance. Landlord shall maintain and
pay for fire insurance, with extended coverage, covering the Building equal to
ninety percent (90%) of the insurable value thereof (i.e., the replacement cost,
less depreciation). Provided, however, if Tenant uses the Premises for any
purpose or in any manner which causes an increase in Landlord's insurance rates,
Tenant shall pay such additional insurance premium (in addition to all other
payments due under this Lease) to Landlord as additional rent within thirty (30)
days after demand from Landlord. Tenant shall maintain and pay for all fire and
extended coverage insurance on its contents in the Premises, including trade
fixtures, equipment, machinery, merchandise or other personal property belonging
to or in the custody of Tenant.

         9. Landlord's Limited Covenant to Repair and Replace. During the Lease
Term, Landlord shall be responsible for repairs or replacements to the roof,
exterior walls and structural members, including foundation and subflooring of
the Premises (except office fronts, plate glass 


8
<PAGE>   9

windows, doors, door closure devices, window and door frames, nailing, locks and
hardware and painting or other treatment of interior and exterior walls, and
except for any repairs and replacements necessitated by an "Event of Tenant
Misconduct" as defined in Paragraph 16(a) herein). Landlord's efforts to repair
and replace pursuant to this paragraph shall be made within a reasonable time
after written notice from Tenant of the need for such repair or replacement to
be made. Without limiting the generality of the foregoing, with respect
particularly to any Emergency Repair, Landlord shall be obligated to commence
repair efforts within five (5) days of its receipt of notice from Tenant of the
need for such Emergency Repair and diligently prosecute such Emergency Repair to
completion ("Landlord's Emergency Repair Obligation"). As used herein,
"Emergency Repair" shall mean any repair which, if made, would cure a condition
having a significant adverse effect on Tenant's operations in the Premises. With
respect to latent or patent defects in the Premises or in the Building,
Landlord's liability shall not extend beyond one year from the date of
substantial completion of the construction of the improvements specified in the
Description of Landlord's Work set forth in Exhibit C hereto, whether or not
such defects are discovered within such one-year period. If Landlord cannot,
using due diligence, complete its repairs and replacements within two hundred
ten (210) days after written notice from Tenant and if the resulting condition
renders a material portion of the Premises untenantable for the Tenant
Operations, then, following the expiration of such two-hundred-ten- (210) day
period and continuing until such time as the repair or replacement is completed
(or is completed sufficiently so as to not render a material portion of the
Premises untenantable for the Tenant Operations), either party may terminate
this Lease effective upon thirty (30) days prior written notice, without
prejudice to Landlord's rights to receive payment from Tenant for uninsured
damages caused directly or indirectly by Tenant as stated below. If the cause of
such repairs or replacements is the result of an Event of Tenant Misconduct,
then Tenant shall not be entitled to terminate this Lease pursuant to this
paragraph, and Tenant shall pay Landlord the full amount of such cost, damage,
and expense (except as otherwise provided in Paragraph 14 herein). Furthermore,
in the event Landlord diligently pursues the completion of the required repairs
and replacements during the two-hundred-ten- (210) day period provided above but
is unable to complete such repairs and replacements prior to the expiration of
such period, such two-hundred-ten- (210) day period shall be extended for all
purposes under this paragraph (including Tenant's termination right) for such
additional, reasonable period of time as is necessary to allow Landlord to
complete such repair or replacement (provided Landlord must continue to pursue
the completion of such repair or replacement in a diligent manner). Landlord's
duty to repair or replace as prescribed in this paragraph shall be Tenant's sole
remedy and shall be in lieu of all other warranties or guaranties of Landlord,
express or implied. Furthermore, the terms of this paragraph shall have no
application to casualty events and exercises of the power of eminent domain that
affect the Building or the Land, which shall be governed by the terms and
provisions in Paragraph 13 herein and Paragraph 18 herein, respectively.

         10. Tenant's Covenant to Repair. Tenant shall be responsible for the
repair, replacement and maintenance in good order and condition of all parts and
components of the Premises, other than those specified for maintenance by
Landlord herein, including, without limitation, the plumbing, wiring, electrical
system, heating system, air conditioning system, glass and plate glass,
equipment and machinery constituting fixtures located within the Premises and
shall keep all plumbing units, pipes and connections free from obstruction and
protected against ice and freezing. At the end of the Lease Term, Tenant shall
return the Premises to Landlord in as good a condition as existed at the time
all of the Landlord's Work and all of the Tenant's Work (if any) was completed
pursuant to Paragraph 3 herein, excepting only normal wear and tear, acts of God
and repairs required to be made by Landlord hereunder. Tenant's duty to maintain
the heating and air conditioning system serving the Premises shall specifically
include the duty to inspect the system, to replace filters as recommended and to
perform other recommended periodic servicing. During the entire Lease Term,
Tenant shall obtain and maintain a service contract with an independent
maintenance contractor reasonably satisfactory to Landlord to provide such
service for the heating and air conditioning system. The service contract must
include all services suggested by the applicable equipment manufacturer(s) in
the operation and maintenance manual(s) and must become effective on the
Occupancy Date. If any repairs required to be made by Tenant hereunder are not
made within thirty (30) days after written notice delivered to Tenant by
Landlord (provided no advance written notice shall be required in cases of
emergency), Landlord may, at its option, make such repairs without liability 


9
<PAGE>   10

to Tenant for any loss or damage which may result to Tenant's stock or business
by reason of such repairs, and Tenant shall pay to Landlord immediately upon
demand, as additional rental hereunder, the cost of such repairs plus ten
percent (10%) of the amount thereof, and failure to do so shall constitute an
Event of Default hereunder.

         11. Trade Fixtures and Equipment; Non-Liability for Certain Damages.

         (a) So long as Tenant is not in default under this Lease, any trade
fixtures and equipment installed in the Premises at Tenant's expense shall
remain Tenant's personal property, and Tenant shall have the right at any time
during the Lease Term to remove such fixtures and equipment. Upon removal of any
fixtures or equipment, Tenant shall immediately restore the Premises to
substantially the same condition as existed at the time all of the Landlord's
Work and all of the Tenant's Work (if any) was completed pursuant to Paragraph 3
herein, ordinary wear and tear and acts of God alone excepted. Any trade
fixtures and equipment not removed by Tenant at the expiration or an earlier
termination of this Lease shall, at Landlord's option, either: (i) become the
property of Landlord or (ii) be removed by Landlord, at Tenant's expense.

         (b) Landlord and Landlord's agents and employees shall not be liable to
Tenant or any other person or entity whomsoever for any injury to person or
damage to property caused by the Premises or other portions of the Center
becoming out of repair or by defect in or failure of equipment, pipes or wiring,
or broken glass, or by the backing up of drains, or by gas, water, steam,
electricity or oil leaking, escaping or flowing into the Premises, nor shall
Landlord be liable to Tenant or any other person or entity whomsoever for any
loss or damage that may be occasioned by or through the acts or omissions of
other tenants of the Center or of any other persons or entities whomsoever,
excepting only duly authorized employees and agents of Landlord. Landlord shall
not be liable to Tenant for any compensation, damages or reduction of rent by
reason of inconvenience or annoyance or loss of business arising from power
losses or shortages or from the necessity of Landlord's entering the Premises
for any of the purposes authorized in this Lease or for repairing the Premises.
Landlord's liability with respect to any defects, repairs or maintenance for
which Landlord is responsible under any provision of this Lease shall be limited
to the cost of such repairs or maintenance or the curing of such defect. Tenant
shall indemnify and hold Landlord harmless from and against any loss, cost,
expense or claims arising out of such injury or damage referred to in this
paragraph.

         12. Utilities. Tenant shall pay in a timely manner and prior to
delinquency for all utilities or services related to its use of the Premises,
including electricity, gas, heat, sewer, water, telephone and janitorial
services. Landlord shall not be responsible for the stoppage or interruption of
utilities services, other than as required by its limited covenant to repair and
replace set forth herein.

         13. Damage or Destruction of Premises. If the Building is so damaged by
fire or other casualty that substantial alteration or reconstruction of the
Building shall be required (whether or not the Premises shall have been damaged
by such casualty) or in the event any mortgagee of Landlord should require that
all or any portion of the insurance proceeds payable as a result of a casualty
be applied to the payment of the underlying mortgage debt, Landlord may, at its
option, terminate this Lease by notifying Tenant in writing of such termination
within sixty (60) days after the date the casualty event occurs. If the Premises
are damaged by fire or other casualty but are not rendered untenantable for
Tenant's business, either in whole or in part, and if Landlord does not
terminate this Lease pursuant to the immediately preceding sentence, Landlord
shall cause such damage to be repaired (to the extent of Landlord's Work)
without unreasonable delay and the Annual Rental shall not be abated. If by
reason of such casualty, the Premises are rendered untenantable for Tenant's
business, either in whole or in part, and Landlord does not terminate this Lease
as provided in the first sentence above in this Paragraph 13, Landlord shall
cause the damage to be repaired or replaced (to the extent of Landlord's Work)
without unreasonable delay, and in the interim, the Annual Rental shall be
equitably reduced as to such portion of the Premises as is rendered
untenantable. Any such abatement of rent shall not, however, create an extension
of the Lease Term. Provided, however, if by reason of such casualty, the
Premises are rendered substantially untenantable, and Landlord fails to give
Tenant reasonable assurances that the amount of time required to repair the
damage, using due diligence, shall not exceed two hundred ten (210) days from
the date the casualty event 


10
<PAGE>   11

occurs, then either party shall have the right to terminate this Lease by giving
written notice of termination within sixty (60) days after the date the casualty
event occurs. Notwithstanding the other provisions of this Paragraph 13, in the
event there is a casualty loss to the Premises to the extent of fifty percent
(50%) or more of the replacement value during the last Lease Year of the Lease
Term, including any extension of the Lease Term that has then been exercised by
Tenant, either party may, at its option, terminate this Lease by giving written
notice within sixty (60) days after the date the casualty event occurs; and, in
such case, rent shall abate as of the later of (i) the date of such termination
notice or (ii) the date that Tenant vacates the Premises (which vacation of the
Premises must occur within thirty (30) days after the date of such termination
notice). Except as provided herein, there shall be no obligation of Landlord to
rebuild or repair in case of fire or other casualty, and no termination under
this Paragraph 13 shall affect any rights of Landlord or Tenant hereunder
because of prior defaults of the other party. Tenant shall give Landlord
immediate notice of any fire or other casualty in the Premises.

         14. Mutual Waiver; Waiver of Subrogation. The parties mutually release
and waive unto the other, all rights to claim damages, costs or expenses for any
injury to persons (including death) or property caused by a casualty of any type
whatsoever in, on or about the Premises, the Building or the Center if the
amount of such damages, costs or expenses either (i) has been paid to such
damaged party under the terms of any policy of insurance or (ii) would have been
paid to such damaged party under the terms of any policy of insurance required
to be carried by such party hereunder if such party had actually procured such
insurance. All insurance policies carried with respect to this Lease, if
permitted under applicable law, shall contain a provision whereby the insurer
waives prior to loss all rights of subrogation against either Landlord or Tenant
(as the case may be).

         15. Signs and Advertising. In order to provide architectural control
for the Center, Tenant may install, at Tenant's expense: only such exterior
signs, marquees, billboards, outside lighting fixtures and/or other decorations
on the Premises as shall have been approved in advance and in writing by
Landlord. The care and maintenance of all such approved signs shall be the sole
responsibility of Tenant. Landlord shall have the right to remove any such sign
or other decoration and fully restore the exterior of the Premises at the cost
and expense of Tenant if any such exterior work is done without Landlord's prior
written approval. Upon the expiration or earlier termination of this Lease,
Tenant shall remove any such sign or decoration and fully restore the exterior
of the Premises, at Tenant's sole cost and expense. Tenant shall not permit,
allow or cause to be used in, on or about the Premises any sound production
devices, mechanical or moving display devices, bright lights, or other
advertising media, the effect of which would be visible or audible from the
exterior of the Premises.

         16. Indemnification, Liability Insurance and Hazardous Substances.

         (a) Indemnification by Tenant. Tenant shall indemnify and save Landlord
harmless against any and all claims, suits, demands, actions, fines, damages and
liabilities and all costs and expenses thereof (including, without limitation,
reasonable attorneys' fees) arising out of injury to persons (including death)
or property occurring in, on or about, or arising out of, the Premises, the
Building or other areas in the Center if caused by or occasioned wholly or in
part by any willful or negligent act or omission of Tenant, its agents,
subtenants, licensees, invitees, contractors, subcontractors or employees
(collectively, an "Event of Tenant Misconduct"). Tenant shall give Landlord
immediate written notice of any such happening causing injury to persons or
property.

         (b) Indemnification by Landlord. Landlord shall indemnify and save
Tenant harmless against any and all claims, suits, demands, actions, fines,
damages and liabilities and all costs and expenses thereof (including, without
limitation, reasonable attorneys' fees) arising out of injury to persons
(including death) or property occurring in, on or about, or arising out of, the
Premises, the Building or other areas in the Center if such damage or injury is
caused by any willful or negligent act or omission of Landlord, its agents or
employees.

         (c) Liability Insurance. At all times during the Lease Term, Tenant
shall, at its own expense, keep in force comprehensive public liability
insurance in such amounts and with such companies as shall, from time to time,
be acceptable to Landlord (and to any mortgagee having a mortgage interest in
the Premises) and naming Landlord as an additional insured. The amounts 


11
<PAGE>   12

of such coverage, until changed at Landlord's request, shall be $1,000,000.00
with respect to bodily injury or death of one person as a result of any one
accident and $500,000.00 with respect to damage to property. Tenant shall first
furnish to Landlord a copy of the required policy or certificate of insurance,
evidencing the required coverage and naming Landlord as an additional insured
under such policy, within five (5) days of the Lease Execution Date and
thereafter prior to each policy renewal date. Such policy also shall include
contractual liability coverage for the performance by Tenant of the indemnity
obligations of Tenant under this Lease, and such policy shall contain a
provision whereby the insurer is not allowed to cancel, fail to renew or
materially change the coverage without first giving thirty (30) days written
notice to Landlord.

         (d) Presence and Use of Hazardous Substances. Tenant shall not, without
Landlord's prior written consent, keep on or around the Premises, the common
areas or facilities in or relating to the Building, the Land, or the Center, for
use, disposal, treatment, generation, storage or sale, any substances designated
as, or containing components designated as, hazardous, dangerous, toxic or
harmful, and/or any substance that is subject to regulation by any then-current
federal, state or local law, statute or ordinance and the rules and regulations
implementing them, including, but not limited to, the Resource Conservation and
Recovery Act (42 U.S.C. ss. 6901 et seq.); the Comprehensive Environmental
Response, Compensation and Liability Act (42 U.S.C. ss. 9601 et seq.); the Clean
Water Act (33 U.S.C. ss. 1251 et seq.); the Clean Air Act (42 U.S.C. ss. 7401 et
seq.); and the Toxic Substances Control Act (15 U.S.C. ss. 2601 et seq.) (such
substances being herein collectively referred to as "Hazardous Substances").
With respect to any such Hazardous Substance, Tenant shall:

                  (1) Comply promptly, timely and completely with all
         governmental requirements for reporting, keeping and submitting
         manifests and obtaining and keeping current identification numbers;

                  (2) Submit to Landlord true and correct copies of all reports,
         manifests and identification numbers at the same time as they are
         required to be and/or are submitted to the appropriate governmental
         authorities;

                  (3) Within five (5) days of Landlord's request from time to
         time, submit written reports to Landlord regarding Tenant's use,
         storage, treatment, transportation, generation, disposal or sale of
         Hazardous Substances and provide evidence satisfactory to Landlord of
         Tenant's compliance with the applicable governmental laws, statutes,
         ordinances, rules, regulations and requirements;

                  (4) Allow Landlord or Landlord's agent or representative to
         enter the Premises at all times to check Tenant's compliance with all
         applicable governmental laws, statutes, ordinances, rules, regulations
         and requirements regarding Hazardous Substances;

                  (5) Comply with minimum levels, standards or other performance
         standards or requirements which may be set forth or established for
         certain Hazardous Substances; and if minimum standards or levels are
         applicable to Hazardous Substances present on the Premises, such
         standards or levels shall be established and documented by an on-site
         inspection by the appropriate governmental authorities and shall be set
         forth in an addendum to this Lease;

                  (6) Comply with all applicable governmental laws, statutes,
         ordinances, rules, regulations and requirements regarding the proper
         and lawful use, sale, transportation, generation, treatment and
         disposal of such Hazardous Substances; and

                  (7) Pay to Landlord upon demand as additional rent any and all
         costs incurred by Landlord and associated with Landlord's inspection of
         the Premises and Landlord's monitoring of Tenant's compliance with this
         Paragraph 16(d), including Landlord's attorneys' fees and costs.

The terms and provisions in this Paragraph 16(d) shall survive the expiration of
the Lease Term or the earlier termination of this Lease.


12
<PAGE>   13

         (e) Unauthorized Releases of Hazardous Substances; Cleanup Costs;
Default and Indemnification.

                  (1) Tenant shall give immediate written notice to Landlord of
         any release, spill, discharge or threatened discharge of any Hazardous
         Substance on or at the Premises, the common areas or facilities in or
         relating to the Building, the Land, the Center, or the surrounding
         environment, which release, spill, discharge or threatened discharge
         was not made pursuant to or in conformance with the terms of any permit
         or license issued to Tenant by the appropriate governmental authority.
         Such notice shall include a description of measures taken or proposed
         to be taken by Tenant to contain and/or remedy the release, spill,
         discharge or threatened discharge and any resultant damage to property,
         persons, the Premises, the common areas or facilities in or relating to
         the Building, the Land, the Center, and/or the surrounding environment.
         Tenant also shall give immediate written notice to Landlord of any
         private or governmental investigation relating to Hazardous Substances
         on or about the Premises.

                  (2) At Tenant's own expense, Tenant shall promptly take all
         steps necessary to contain and remedy any release, spill, discharge or
         threatened discharge of Hazardous Substances on or at the Premises, the
         common areas or facilities in or relating to the Building, the Land,
         the Center, or the surrounding environment, and all resultant damage or
         injury to property, persons, and the environment. Landlord shall have
         the right, but not the obligation, to participate in and approve any
         environmental assessment or remedial cleanup plan for the Premises, the
         common areas or facilities in or relating to the Building, the Land and
         the Center. Tenant, its employees, agents and contractors shall fully
         cooperate with any and all federal, state and local governmental
         officials having jurisdiction over the Premises in resolving or
         addressing any situation involving the presence of Hazardous Substances
         on or about the Premises.

                  (3) Tenant shall be fully and completely liable to Landlord
         for any and all cleanup costs and any and all other charges, fees, and
         penalties (civil and criminal) imposed by any governmental authority
         with respect to Tenant's use, generation, handling, storage,
         containment, disposal, transportation, and/or sale of Hazardous
         Substances.

                  (4) Tenant shall indemnify, defend and save Landlord harmless
         from any and all of the costs, fees, penalties and charges assessed
         against or imposed upon Landlord (as well as Landlord's attorneys' fees
         and costs) as a result of Tenant's use, generation, handling, storage,
         containment, disposal, transportation, and/or sale of Hazardous
         Substances.

                  (5) Upon Tenant's default under Paragraph 16(d) herein or this
         Paragraph 16(e) and in addition to the rights and remedies set forth
         elsewhere in this Lease, Landlord shall be entitled to the following
         rights and remedies:

                           (A) At Landlord's option, to terminate this Lease
                  immediately; and

                           (B) To recover any and all damages associated with
                  the default,

including, but not limited to, cleanup costs and charges, civil and criminal
penalties and fees, loss of business and sales by Landlord and other tenants of
the Building or the Center, any and all damages and claims asserted by third
parties, and Landlord's attorneys' fees and costs.

The terms and provisions in this Paragraph 16(e) shall survive the expiration of
the Lease Term or the earlier termination of this Lease.

         17. Landlord's Right of Entry. Landlord and those persons authorized
by Landlord shall have the right to enter the Premises at all reasonable times
and upon reasonable notice for the purposes of making repairs, making
connections, installing utilities, providing services to the Premises or for any
other tenant, making inspections or showing the Premises to prospective
purchasers and/or lenders. Further, during the last six (6) months of the Lease
Term, including any extended Lease Term that has then been exercised by Tenant,
Landlord and those persons 


13
<PAGE>   14

authorized by it shall have the right, at reasonable times and upon reasonable
notice to Tenant, to show the Premises to prospective tenants. Notwithstanding
any term or provision in this Lease, including this Paragraph 17, to the
contrary, Landlord shall be entitled to enter the Premises at all times and
without any advance notice to Tenant if Landlord reasonably determines or
believes that an emergency circumstance or situation exists that requires such
entry.

         18. Eminent Domain. If any substantial portion of the Premises is taken
under the power of eminent domain (including any conveyance made in lieu
thereof) or if any such taking shall materially impair the normal operation of
Tenant's business, then either party shall have the right to terminate this
Lease by giving written notice of such termination within thirty (30) days after
such taking. If neither party elects to terminate this Lease pursuant to the
immediately preceding sentence, Landlord shall repair and restore the Premises
to a tenantable condition and the Annual Rental shall be equitably reduced as to
the portion of the Premises that is taken. All compensation awarded for any
taking (or the proceeds of a private sale in lieu thereof) shall be the property
of Landlord, whether such award is for compensation for damages to Landlord's or
Tenant's interest in the Premises, and Tenant hereby assigns all of its interest
in any such award to Landlord; provided, however, Landlord shall not have any
interest in any separate award made to Tenant for loss of business, moving
expenses or the taking of Tenant's trade fixtures or equipment if a separate
award for such items is made to Tenant.

         19. Events of Default and Landlord's Remedies.

         (a) Upon the occurrence of any one or more of the following events
(each, an "Event of Default"; collectively, "Events of Default"), Landlord shall
be entitled to exercise any rights or remedies available in this Lease, at law
or in equity. Events of Default shall be:

                  (1) Tenant's failure to pay when due any rental or other sum
         of money payable hereunder if not remedied within five (5) days after
         written notice thereof is given to Tenant (provided, however, and
         notwithstanding the foregoing to the contrary, Tenant shall not be
         entitled to such notice and cure period more than two (2) times during
         any given Lease Year).

                  (2) Failure by Tenant to perform any of the other terms,
         covenants or conditions contained in this Lease if such failure is not
         remedied within thirty (30) days after written notice thereof is given
         to Tenant.

                  (3) Tenant, or any guarantor of Tenant's obligations under
         this Lease (if any), becomes bankrupt or insolvent, files any debtor
         proceedings, files pursuant to any statute a petition in bankruptcy or
         insolvency or for reorganization, or files a petition for the
         appointment of a receiver or trustee for all or substantially all of
         such party's assets and such petition or appointment is not set aside
         within sixty (60) days from the date of such petition or appointment or
         if such party makes an assignment for the benefit of creditors or
         petitions for or enters into such an arrangement.

                  (4) Tenant vacates, abandons, or fails to operate in the
         Premises (or any substantial part thereof) or allows its leasehold
         estate under this Lease to be taken under any writ of execution and
         such writ is not vacated or set aside within thirty (30) days.

         (b) In addition to its other remedies at law or in equity, Landlord,
upon an Event of Default by Tenant, shall have the immediate right to reenter
and remove all persons and property from the Premises and dispose of such
property as it deems fit, all without resort to legal process and without being
guilty of trespassing or being liable for any damages caused thereby; provided,
however, Landlord may undertake the foregoing actions without resort to legal
process only if such actions can be completed in a manner that does not violate
applicable laws and legal requirements and without causing a disturbance of the
peace. If Landlord reenters the Premises, either with or without legal process
(subject to the limitations in the preceding sentence), it may either terminate
this Lease or, from time to time without terminating this Lease, make such
alterations and repairs as may be necessary or appropriate to relet the
Premises, and relet the Premises upon such terms and conditions as Landlord
deems advisable, without any responsibility of Landlord whatsoever to account to
Tenant for any surplus rents collected. Tenant also shall be liable for and
shall pay to Landlord, in addition to any other sum provided to 


14
<PAGE>   15

be paid herein, brokers' fees incurred by Landlord in connection with reletting
the whole or any part of the Premises; the costs of removing from the Premises
and storing Tenant's or other occupants' property; the costs of repairing,
altering, remodeling or otherwise putting the Premises into condition acceptable
to a new tenant or tenants, and all reasonable expenses incurred by Landlord in
enforcing or defending Landlord's rights and/or remedies under this Lease,
including reasonable attorneys' fees. No retaking of possession of the Premises
by Landlord shall be deemed as an election to terminate this Lease unless a
written notice of such intention is given by Landlord to Tenant at the time of
reentry; but, notwithstanding any such reentry or reletting without termination,
Landlord may at any time thereafter elect to terminate this Lease for such
previous default. In the event of an elected termination of this Lease by
Landlord, whether before or after reentry, Landlord may recover from Tenant
damages, including the costs of recovering the Premises, and Tenant shall remain
liable to Landlord for the total Annual Rental (which may, at Landlord's
election, be accelerated to be due and payable in full as of the Event of
Default or at any time thereafter and recoverable as damages in a lump sum) that
would have been payable by Tenant hereunder for the remainder of the Lease Term,
less the rentals actually received by Landlord from any reletting. (In the event
of any such acceleration, in determining the Annual Rental which would be
payable by Tenant subsequent to default, the Annual Rental rate for each
calendar year of the unexpired Lease Term shall be equal to the Annual Rental
rate payable by Tenant for the last calendar year prior to the default). If any
rent owing under this Lease is collected by or through an attorney, Tenant
agrees to pay Landlord's reasonable attorneys' fees to the extent allowed by
applicable law.

         20. Subordination. This Lease is subject and subordinate to any and all
mortgages or deeds of trust now or hereafter placed upon the property of which
the Premises are a part, and this clause shall be self-operative, without any
further instrument necessary to effect such subordination, provided any such
lender may, at its option and without seeking or obtaining Tenant's consent,
subordinate the lien of its mortgage or deed of trust to this Lease. At the
request from time to time of Landlord or any lender that holds a mortgage or
deed of trust on the property of which the Premises are a part, Tenant shall
promptly execute and deliver to Landlord any such instrument or instruments as
Landlord or such lender may reasonably request evidencing the subordination of
this Lease to such mortgage or deed of trust. Provided, however, as a condition
to Tenant's obligation to execute and deliver any such instrument(s), the
applicable lender must agree that Tenant's rights to quiet enjoyment and
possession of the Premises under this Lease shall not be divested by foreclosure
or other default proceedings under the applicable mortgage or deed of trust so
long as Tenant shall not be in default under this Lease. Tenant shall continue
its obligations under this Lease in full force and effect, notwithstanding any
foreclosure or default proceedings by any such lender.

         21. Assigning and Subletting. Tenant shall not assign, sublet,
mortgage, pledge or encumber this Lease, the Premises, or any interest in the
whole or in any portion thereof, without the prior written consent of Landlord
(which consent shall not be unreasonably withheld). If Tenant makes any such
assignment, mortgage, sublease or pledge (whether with or without Landlord's
written consent), Tenant named herein and any guarantor of Tenant's obligations
under this Lease shall nonetheless remain primarily liable for the performance
and observation of all of the terms of this Lease required to be observed or
performed by Tenant hereunder. Any rental or any fee or charge received by
Tenant in connection with any such assignment or sublease which is in excess of
the Annual Rental payable to Landlord hereunder shall be paid immediately by
Tenant to Landlord as additional rental under this Lease. In addition, Landlord
shall have the option, in its sole discretion, to terminate this Lease effective
as of the proposed effective date of any assignment or sublease, by giving
Tenant written notice thereof within thirty (30) days after Landlord's receipt
of said notice from Tenant; and in the event Tenant shall propose to sublet only
a portion of the Premises, Landlord shall have the additional option to
terminate this Lease as to that portion of the Premises proposed to be sublet.
Should Landlord not elect to so terminate this Lease in connection with any
proposed subletting or assignment, Landlord shall continue to have the right to
disapprove same (subject to the terms above). Upon any subletting or assignment
by Tenant in accordance with the terms hereof, any renewal options, expansion
options, and/or rights of first refusal granted herein shall become null and
void. Consent by Landlord to one or more assignments or sublettings shall not
operate as a waiver of Landlord's rights as to any subsequent assignments or
sublettings.


15
<PAGE>   16

         22. Covenant of Quiet Enjoyment. Landlord represents that it has full
right and authority to lease the Premises and that Tenant shall peacefully and
quietly hold and enjoy the Premises for the full Lease Term so long as Tenant
does not default in the performance of any of the terms hereof.

         23. Estoppel Certificates. Within ten (10) days after any request by
Landlord, Tenant shall deliver a written estoppel certificate addressed to
Landlord and/or any other party designated by Landlord, certifying any facts
that are then true with respect to this Lease, including, without limitation,
that this Lease is in full force and effect, that no default exists on the part
of Landlord or Tenant hereunder, that Tenant is in possession of the Premises,
that Tenant has commenced the payment of rent hereunder, and that there are no
defenses or offsets claimed by Tenant with respect to payment of rentals under
this Lease.

         24. Protection Against Liens. Tenant shall do all things necessary to
prevent the filing of any mechanic's, materialmen's or other types of liens
whatsoever, against all or any part of the Premises, the Building, the Land or
the Center by reason of any claims made by, against, through or under Tenant. If
any such lien is filed against the Premises, the Building, the Land or the
Center (or any portion thereof), Tenant shall either cause the same to be
discharged of record within twenty (20) days after filing or, if Tenant, in its
discretion and in good faith, determines that such lien should be contested,
Tenant shall furnish such security as may be necessary to prevent any
foreclosure proceedings against the Premises, the Building, the Land or the
Center (or any portion thereof) during the pendency of such contest. If Tenant
shall fail to discharge such lien within said time period or fail to furnish
such security, then Landlord may, at its election and in addition to any other
right or remedy available to it, discharge the lien by paying the amount claimed
to be due or by procuring the discharge by giving security or in such other
manner as may be allowed by law. If Landlord acts to discharge or secure any
such lien as permitted herein, then Tenant shall immediately reimburse Landlord
(as additional rent) for all sums paid and all costs and expenses (including
reasonable attorneys' fees) incurred by Landlord relative to such lien, together
with interest on the total expenses and costs at the maximum lawful rate.

         25. Force Majeure. Whenever a period of time is herein prescribed for
the taking of any action by Landlord, Landlord shall not be liable or
responsible for, and there shall be excluded from the computation of such period
of time, any delays due to any condition, matter or circumstance beyond the
reasonable control of Landlord (collectively, "Force Majeure Matters"; each, a
"Force Majeure Matter"), including, without limitation, the following: strikes;
defaults or failures to perform by contractors or subcontractors; lockouts; acts
of God; governmental restrictions, war or enemy action or invasion; civil
commotion; insurrection; riot; mob violence; malicious mischief or sabotage;
fire or any other casualty; adverse weather conditions or unusual inclement
weather; condemnation; unavailability of materials; failure of a governmental
instrumentality to act in a timely fashion; any litigation or other legal
proceeding which delays the approval of plans or the issuance of any grading or
building permit for construction, including, without limitation, the issuance of
an injunction enjoining such approval and/or issuance, as the case may be; any
law, order or regulation of any governmental, quasi-governmental, judicial or
military authority; or other similar cause. Without limiting the generality of
the foregoing, in the event a Force Majeure Matter affects Landlord's
construction and delivery obligation(s) relative to the Premises under this
Lease, the period of time during which Landlord may complete such construction
and delivery obligation(s) shall be extended by the same number of days as the
number of days of delay caused by such Force Majeure Matter on the critical path
of completing such construction and delivery obligation(s).

         26. Nonwaiver. No course of dealing between Landlord and Tenant and no
delay or omission of Landlord in exercising any right arising from Tenant's
default shall impair such right or be construed to be a waiver of a default.

         27. Landlord Liability. All obligations of Landlord hereunder will be
construed as covenants, not conditions, and all such obligations will be binding
upon Landlord only during the period of its ownership and possession of the
Building and not thereafter. The term "Landlord," under this Lease, shall mean
only the owner, for the time being, of the Building. If Landlord shall sell,
assign or transfer all or any part of its interest in the Premises or in this
Lease to a 


16
<PAGE>   17

successor in interest which expressly assumes the obligations of Landlord
hereunder, then the selling, assigning or transferring Landlord shall thereupon
be released and discharged from all covenants and obligations hereunder, and
Tenant shall look solely to such successor in interest for the performance of
all of Landlord's obligations hereunder. Tenant's obligations under this Lease
shall in no manner be affected by Landlord's assignment or transfer hereunder,
and Tenant shall thereafter attorn and look solely to such successor in interest
as the landlord hereunder. Notwithstanding any other provision hereof, Landlord
shall not have any personal liability hereunder. In the event of any breach or
default by Landlord in any term or provision of this Lease, Tenant agrees to
look solely to Landlord's interest in the Land and the Building; however, in no
event shall any deficiency judgment or any money judgment of any kind be sought
or obtained against Landlord.

         28. Holding Over. If Tenant remains in possession of the Premises or
any part thereof after the expiration of the Lease Term, whether with or without
Landlord's acquiescence, Tenant shall be deemed only a tenant at will and there
shall be no renewal of this Lease without a written agreement signed by both
parties specifying such renewal; in addition, the monthly Minimum Rental
required to be paid under this Lease relative to any holdover period shall
automatically become one hundred fifty percent (150%) of the monthly Minimum
Rental payable immediately prior to the expiration of the Lease Term. Tenant
also shall be liable for any and all damages, direct and consequential, suffered
by Landlord as a result of any holdover without Landlord's unequivocal written
acquiescence.

         29. Notices. Any notice allowed or required by this Lease shall be
deemed to have been sufficiently served if the same shall be in writing and
placed in the United States Mail, via certified mail or registered mail, return
receipt requested, with proper postage prepaid and addressed:

                  AS TO LANDLORD: To Landlord's address set forth in the Basic 
                                    Lease Information.

                  AS TO TENANT:   Prior to the Occupancy Date, to Tenant's 
                                    address set forth in the Basic Lease 
                                    Information.

                                    From and after the Occupancy Date, to the 
                                    Premises.

         The addresses of Landlord and Tenant to which notices shall be directed
may be changed or added from time to time by either party giving notice to the
other in the prescribed manner.

         30. Miscellaneous.

         (a) Rules and Regulations. Attached hereto as Exhibit D are the rules
and regulations currently in effect with respect to the Building. Landlord shall
have the right from time to time to reasonably amend these rules and regulations
for Tenant's use of the Premises, the Building and the Land. Tenant shall abide
by and actively enforce such rules and regulations, including, without
limitation, rules and regulations governing parking of vehicles on designated
portions of the Land as to its employees, agents, invitees and licensees.

         (b) Evidence of Authority. If requested by Landlord, Tenant shall
furnish appropriate legal documentation evidencing the valid existence and good
standing of Tenant and the authority of any parties signing this Lease on behalf
of Tenant to act for Tenant.

         (c) Nature and Extent of Agreement. This Lease, together with all
exhibits hereto, contains the complete agreement of the parties concerning the
subject matter hereof, and there are no oral or written understandings,
representations, or agreements pertaining thereto which have not been
incorporated herein. This Lease creates only the relationship of landlord and
tenant between the parties, and nothing herein shall impose upon either party
any powers, obligations or restrictions not expressed herein. This Lease shall
be construed and governed by the laws of the state in which the Premises are
located.

         (d) Severability. If any term or provision of this Lease, or the
application thereof to 


17
<PAGE>   18

any person or circumstance shall, to any extent, be invalid or unenforceable,
the remainder of this Lease, or the application of such term or provision to
persons or circumstances other than those as to which it is held invalid or
unenforceable, shall not be affected thereby, and each term and provision of
this Lease shall be valid and enforced to the fullest extent permitted by law,
notwithstanding the invalidity of any other term or provision hereof.

         (e) Binding Effect. This Lease shall be binding upon and shall inure to
the benefit of the parties hereto and their respective heirs, successors and
assigns. This Lease shall not be binding on Landlord until executed by an
officer of Landlord having a title of Vice President or higher and delivered to
Tenant. No amendment or modification of this Lease shall be binding upon
Landlord unless same is in writing and executed by an officer of Landlord having
a title of Vice President or higher.

         (f) Captions and Headings. The captions and headings in this Lease are
for convenience and reference only, and they shall in no way be held to explain,
modify, or construe the meaning of the terms of this Lease.

         (g) Security Deposit. Tenant shall pay to Landlord on the Lease
Execution Date a sum (the "Security Deposit") equal to one month's Minimum
Rental as security for the performance of all obligations to be performed by
Tenant hereunder. The Security Deposit may be held by Landlord in such manner as
it shall elect, and Landlord shall be entitled to retain any interest which
accrues on the Security Deposit. In the event of a default by Tenant hereunder,
Landlord may, at its option, apply all or any part of the Security Deposit to
cure the default, and thereupon Tenant shall immediately redeposit with Landlord
the amount so applied in order that Landlord will always have the full Security
Deposit on hand during the Lease Term. Upon the termination of this Lease and
provided that Tenant is not in default hereunder, Landlord shall refund to
Tenant any of the remaining balance of the Security Deposit, subject to final
adjustments for payment of any rental required to be paid by Tenant under this
Lease and compliance by Tenant with all of its obligations hereunder. If the
Premises are sold, Landlord shall transfer the Security Deposit to the new
owner; and upon such transfer, Landlord shall thereupon be released from all
liability for the Security Deposit, and Tenant thereafter shall look solely to
the new owner for the Security Deposit. The terms of the immediately preceding
sentence shall apply to every transfer of the Security Deposit.

         (h) Lease Review. The submission of this Lease to Tenant for review
does not constitute a reservation for or option for the Premises, and this Lease
shall become effective as a contract only upon execution and delivery by
Landlord and Tenant.

         (i) Brokerage. Landlord warrants and represents to Tenant that Landlord
has not engaged or contracted with any person, firm or entity to serve or act as
a Realtor(R), broker, agent or finder, other than Broker (if any) identified in
the Basic Lease Information, for the purpose of leasing the Premises or in
regard to this Lease. Tenant warrants and represents to Landlord that Tenant has
not engaged, contracted with or dealt with any person, firm or entity (other
than Broker, if any) to serve or act as a Realtor(R), broker, agent or finder
for the purpose of leasing the Premises or in regard to this Lease. Landlord
agrees to be solely responsible for the payment of any commission to Broker (if
any) relating to this Lease pursuant to a separate agreement between Landlord
and Broker (if any). Tenant shall and does hereby indemnify and hold harmless
Landlord from and against any claim for any consulting fee, finder's fee,
commission, or like compensation, including reasonable attorneys' fees in
defense thereof, payable in connection with this Lease and asserted by any party
arising out of any act or agreement by Tenant, excluding the commission payable
by Landlord to Broker (if any) as described above. Landlord shall and does
hereby indemnify and hold harmless Tenant from and against any claim for any
consulting fee, finder's fee, commission, or like compensation, including
reasonable attorneys' fees in defense thereof, payable in connection with this
Lease and asserted by any party arising out of any act or agreement by Landlord
(including the commission payable by Landlord to Broker, if any, as described
above).

         (j) Memorandum of Lease. Upon the request of either party, the other
party shall join in the execution of a memorandum of this Lease (a "Memorandum")
in recordable form. Either party may record the Memorandum in the appropriate
land record office, at its own expense. However, neither party shall record this
Lease (or any portion thereof) without the written consent of the other party.


18
<PAGE>   19

         (k) Advance Rental Payment.  [Intentionally deleted.]

         (l) Landlord's Consent. Whenever this Lease requires Landlord's consent
to or approval of any item or matter, Landlord may condition such consent or
approval on payment or reimbursement by Tenant of all costs and expenses
incurred by Landlord in connection with reviewing and responding to such item or
matter.

         (m) Survival of Obligations. Notwithstanding any term or provision in
this Lease to the contrary, any liability or obligation of Landlord or Tenant
arising during or accruing with respect to the Lease Term shall survive the
expiration or earlier termination of this Lease, including, without limitation,
obligations and liabilities relating to (i) rental payments, (ii) the condition
of the Premises and the removal of Tenant's property, and (iii) indemnity and
hold harmless provisions in this Lease.

         (n) Confidentiality. Tenant shall not disclose the terms of this Lease
to any third party except (i) legal counsel to Tenant, (ii) any assignee of
Tenant's interest in this Lease or any sublessee of Tenant relative to the
Premises (or any portion thereof), (iii) as required by applicable law or by
subpoena or other similar legal process, or (iv) for financial reporting
purposes.

         (o) Attorneys' Fees. In the event either party defaults in the
performance of any of the terms of this Lease and the other party employs
attorney(s) in connection therewith, the defaulting party agrees to pay the
prevailing party's reasonable attorneys' fees (calculated at such attorneys'
reasonable and customary hourly rates and without regard to the amount in
controversy) and costs of litigation.

         (p) Time of Performance. Except as expressly otherwise herein provided,
with respect to all required acts of Tenant, time is of the essence of this
Lease.

         (q) Real Estate Investment Trust. During the Lease Term, should a real
estate investment trust become Landlord hereunder, all provisions of this Lease
shall remain in full force and effect except as modified by this Paragraph
30(g). If Landlord in good faith determines that its status as a real estate
investment trust under the provisions of the Internal Revenue Code of 1986, as
heretofore or hereafter amended, will be jeopardized because of any provision of
this Lease, Landlord may request reasonable amendments to this Lease and Tenant
will not unreasonably withhold, delay or defer its consent thereto, provided
that such amendments do not (a) increase the monetary obligations of Tenant
pursuant to this Lease or (b) in any other manner adversely affect Tenant's
interest in the Premises.

         (r) Additional Terms and Provisions. The additional terms and
provisions, if any, set forth on Exhibit E attached to this Lease are
incorporated herein by reference. If there is no Exhibit E attached to this
Lease, there are no such additional terms and provisions. If there is an Exhibit
E attached to this Lease, the additional terms and provisions set forth thereon
shall control if in conflict with any of the terms and provisions of this Lease.

         IN WITNESS WHEREOF, the parties have caused this Lease to be duly
executed under seal as of the Lease Execution Date pursuant to authority duly
given.

                                             LANDLORD:

                                 Lease Agreement

                        Description of Land and Building



         The Land is located partially in North Carolina and partially in South
Carolina and consists of that certain parcel of land bounded (i) on the west by
the centerline of Stateline Drive, (ii) on the north by the centerline of
Greenway Industrial Drive, (iii) on the east by the centerline of Southstate
Drive (private), and (iv) on the south by the northerly line of the property
owned by B & D Distribution, Inc. (Black & Decker) and that line extended to
Stateline Drive. The Land is sometimes referred to as Tract 3-A and is described
and shown as such on subdivision plats of a portion of Lakemont Industrial Park
recorded in the York County, South Carolina public registry (Plat Book 122, Page
116) and Mecklenburg County, North Carolina.

         The Land is subject to the rights-of-way for Stateline Drive, Greenway
Industrial Drive and Southstate Drive and shall be subject to Landlord's
reservation of a right-of-way for the road located substantially as shown as
Southstate Drive on the map attached hereto as Exhibit B, and Tenant shall have
the right to use, for ingress and egress to and from the Land that portion of
the right-of-way shown as Southstate Drive located beyond the boundary of the
Land, substantially as shown on Exhibit B. Landlord and Tenant agree to share
equally the cost of improving and maintaining Southstate Drive in its present
location.

         A map showing generally the location of the Land and Building is
attached hereto as Exhibit B.

         "broom clean," "AS-IS,"in substantially the same condition as they
