<PAGE>

         5. The cost of all maintenance programs to service the Premises. The
inclusion of the improvements, facilities and services set forth by the
definition of Operating Expenses shall not be deemed to impose an obligation
upon Landlord to either have said improvements or facilities or to provide those
services unless the building already has the same, Landlord already provides the
services or Landlord has agreed elsewhere in this Lease to provide the same or

the Tenant. If within 30 calendar days of receipt of Landlord's statement,
Tenant contests any increase in Operating Expenses, Tenant shall have the right
to inspect Landlord's records relating to Operating Expenses and, if Landlord
and Tenant are still unable to agree on the increase in Operating Expenses for
the current lease year, the matter shall be referred to an independent certified
public accountant who will calculate the increase to Tenant's share of Operating
Expenses. The cost of such independent certified public accountant shall be
shared equally by Landlord and Tenant. For the first calendar year, the Tenant's
estimated pro rata share of Landlord's Operating Expenses shall be $4,141.67 per
month. Each installment of Tenant's share of Operating Expenses shall be payable
by Tenant on the first day of each month during the Term with the Base Rent
referred to in Article 3. The total amount to be remitted by Tenant to Landlord

</TABLE>

         Landlord shall deliver to Tenant as soon as possible after the
expiration of each calendar year a reasonably detailed statement showing
Tenant's share of the actual Operating Expenses incurred during the preceding
year. If Tenant's payments under this Article during said preceding year were
less than Tenant's share as indicated on said statement, Tenant shall pay to
Landlord the amount of the deficiency within thirty (30) calendar days after
delivery by Landlord to Tenant of said Statement. If Tenant's payments under
this Article during said preceding year were more than Tenant's share as
indicated on said statement, Tenant shall receive a credit from Landlord equal
to the amount of such overage. Such credit shall be applied against the charges
due from Tenant in the month following said statement. If such statement is
delivered to Tenant during the last month of the Term of this Lease or after the
expiration of the Term of this Lease, Landlord shall reimburse Tenant in cash
for any overpayment and such responsibility shall survive the Term of this
Lease.

         Tenant's share of all of the Operating Expenses shall be determined by
totaling all of those costs and multiplying it by a fraction, the numerator of
which shall be the number of leasable square feet in the Premises and the
denominator shall be the total number of gross leasable square feet in the
building of which the Premises is a part. If the floor area of the Premises or
the building of which the leased Premises are a part is changed during the
original Term or any renewal Term of this Lease, Tenant's pro rata share shall
be determined as provided above.

         If Tenant commences occupying the Premises other than on January 1 of
any year, or vacates the Premises prior to December 31 of any year, the charges
for reimbursement of Landlord's charges for Operating Expenses shall be pro
rated, based upon the actual time Tenant was in possession of the Premises at
the beginning of the Lease and also at the end of the Lease.

filters and lubricating the HVAC system. Such maintenance and repair and service
contract shall be included in Operating Expenses as described in Article 3C
hereof.
     Tenant shall keep the Premises free and clear of rodents, bugs and vermin,
and Tenant shall use, at its cost and at such intervals as Landlord shall
reasonably require, a reputable pest extermination contractor to provide
extermination services in the Premises. Notwithstanding the above, if Landlord
reasonably determines that an extermination service needs to be provided to the
entire Building in order to eliminate pests from the entire Building, Landlord
shall contract for such extermination services and include the cost of such
services in Operating Expenses. Landlord shall provide Tenant with advance

<PAGE>

notice of any such extermination services to be made to the Premises by Landlord
within a reasonable period of time.

         Tenant shall keep the Premises clean and orderly and shall not cause
the common areas to become disorderly, cluttered, dirty or trashed at any times
and shall not cause refuse to accumulate around any portion of the Property.
Trash shall be stored in a sanitary and inoffensive manner inside the Premises
or in screened areas approved by Landlord, and Tenant shall cause the same to be
removed at reasonable intervals.

         Landlord shall provide Tenant with five suite keys at no cost to
Tenant. All keys are on "Do Not Duplicate" blanks, and numbered for Tenant's
security. These keys cannot be reproduced unless they are done by Landlord's
locksmith . If additional keys are required by Tenant, Tenant shall contact
Landlord in order that Landlord may authorize the issuance of such keys. The
cost of any such additional keys shall be the responsibility of Tenant to pay.

Article 14.       ALTERATIONS AND ADDITIONS:

         After Tenant occupies the Premises, Tenant, at its expense, shall have
the right to make changes in the interior of the Premises, other than major
structural changes, as it shall deem necessary or advisable in adapting the
Premises for its use. No structural changes shall be made without the prior
written consent of Landlord. To the extent such changes are not covered by the
Tenant Improvement Rent. Tenant shall be responsible for any and all costs
associated with said improvements made after Tenant occupies the Premises and
shall be responsible to obtain any and all necessary building permits, use and
occupancy permits, etc. from any and all governmental agencies or authorities as
may be applicable.

         All fixtures shall become a part of the Premises and the property of
the Landlord at the termination of the Lease, except that trade fixtures, and
other fixtures installed by Tenant shall be considered as its own, and Tenant
may recover the same at any time during the Term of this Lease or any extension
thereof, provided that Tenant shall repair any damage caused to the Premises by
such removal.

Article 15.       DAMAGE OR DESTRUCTION OF IMPROVEMENTS:

         In the event the Premises shall be rendered untenable by fire or other
casualty, Landlord will, within sixty (60) calendar days from the date of said
damage or destruction, repair or replace the Premises to substantially the same
condition as prior to the damage or destruction. If Landlord fails to commence
repair of the damage or destruction within thirty (30) calendar days from the
date of such damage or destruction, or if the Premises have not been replaced or
repaired to such condition within sixty (60)) calendar days, Tenant may, at its
option, upon written notice to the Landlord, terminate this Lease. The rent
herein required to be paid shall abate during the period of such
untenantability.

         If the Premises shall be damaged in part by fire or other casualty but
still remains tenantable, Landlord shall repair the Premises to substantially
the same condition as prior to the damage. Landlord shall commence repair of the
damage or destruction within thirty (30) calendar days from the date of
occurrence. During the period of such repairs and restoration, the Lease shall
continue in full force and effect; provided, however, that Tenant shall be
required to pay the rent, herein reserved, abated by the percentage of area
destroyed as compared to the total area herein demised. Said percentage shall be
established within ten (10) calendar days following the damage.

         In the event that any damage or destruction occurs during the last
twelve (12) months of the original Term of this Lease or any extension of the
Term, to the extent of fifty percent (50%) or more of the insurable value of the
Tenant's Premises or the entire building of which the Premises is a part,
Landlord or Tenant may elect to terminate this Lease as of the date of the
destruction or damage, by giving notice of such election within fifteen (15)
calendar days after such damage or destruction. In such event, Landlord shall
receive the proceeds of the insurance policies without obligation to rebuild or
restore the Premises, and Tenant shall execute any waiver which may be required
of it by any insurer or Landlord.

         Any dispute which arises under this Article regarding the usability of
the Premises and reasonable rent shall be settled by arbitration pursuant to the
provisions of Article 28.

<PAGE>

Article 16.       LANDLORD'S RIGHT TO ACCESS:

         Tenant shall permit Landlord and its agents to enter upon the Premises
at all reasonable times during business hours to examine the condition of the
same, provided that Landlord gives Tenant a twenty-four (24) hour notice of said
inspection, and that said inspection does not interfere adversely with the
conduct of the Tenant's daily business, except in case of emergency, and shall
permit Landlord to make such repairs as may be required.

         Tenant shall permit Landlord and its agents to enter upon the Tenant's
Premises at all reasonable times to make repairs or construct improvements to
the Building or the Premises for the benefit of Tenant or other occupants of the
Building or Property provided such repairs or additional improvements do not
substantially impair or diminish the Tenant's use of the Premises. Landlord
shall give Tenant a notice period of at least twenty four (24) hours for repairs
and three (3)business days for constructing improvements before entering the
Premises for such purposes. Landlord shall use its best efforts to minimize any
disruption of the Tenant's operations as a result of such entry into the
Premises.

     Tenant shall permit Landlord, for a period of sixty (60) calendar days
prior to the expiration of the Term of this Lease, to place upon the Premises
the usual "For Rent" or "For Sale" signs, and shall permit Landlord and its
agents, at reasonable times and upon twenty-four (24) hours notice, to show the
Premises to prospective tenants or purchasers.

Article 17.       SURRENDER OF PREMISES:

         Tenant shall surrender and deliver up the Premises and appurtenances at
the end of the Term broom clean and in as good condition and order as they were
on the Commencement Date of the Term hereof, reasonable use and ordinary wear
and tear thereof and leasehold improvements made with Landlord's consent
excepted. Tenant may remove all trade fixtures, signs, equipment, stock and
trade, and other items of a similar nature used in connection with its business,
including such as may have been temporarily attached to the realty, provided all
rents stipulated to be paid hereunder have been paid and all damage to the
Premises is properly repaired. If said removal results in injury to or
defacement of the Premises, Tenant shall immediately repair the Premises at its
expense.

Article 18.       SIGN:

         The Tenant, at Tenant's expense, shall have the privilege and right of
placing, where provided by Landlord, one (1) sign on the front door of the
Premises and one (1) sign on the building, if available, as it deems necessary
and proper in the conduct of its business subject to Landlord's prior written
approval, which approval may not be unreasonably withheld. All signs will
conform to the size, location, and quality as determined by the Landlord and as
specified on Exhibit "F". Tenant shall comply with all laws, ordinances, plat
and deed restrictions, and lawful municipal regulations applicable to the
erection, maintenance, and removal of such signs. Tenant shall be responsible
for the removal of such signs upon surrender of the Premises. Any damage to any
improvements caused by such removal shall be repaired by Tenant within ten
calendar days written notice from Landlord at Tenant's expense. If such damage
has not been restored by Tenant within such ten (10) day notice period, Landlord
may cause such damage to be repaired and charge Tenant for the cost of such
repairs.

Article 19.       ASSIGNMENT AND SUBLETTING:

         Tenant shall have the right to assign this lease or sublet all or a
portion of the Premises to any subsidiary of Tenant provided Tenant remains
financially responsible for performance of the terms of the lease without the
consent of Landlord.

         Additionally, Tenant shall have the right, with the prior written
consent of the Landlord, which consent shall not be unreasonably withheld, to
assign this Lease or sublet all or any portion of the Premises to a party
unrelated to Tenant provided Tenant remains financially responsible for
performance of the terms of the Lease. In such circumstance, Landlord shall not
impose any compensation requirements as a condition of its consent. Further,
Tenant shall retain any profits from such sublease, regardless of relationship
to Tenant.

<PAGE>

Article 20.       EMINENT DOMAIN:

         If the entire Premises, or such part thereof, as, in the Landlord's
judgment, renders the remainder unsuitable for Tenant's continued use, shall be
taken in appropriate proceedings or by any rights of eminent domain, then this
Lease shall terminate and be utterly void from the time when possession thereof
is required for public use, and such taking shall not operate as or be deemed an
eviction of Tenant or a breach of Landlord's covenant for quiet enjoyment; but
Tenant shall pay all rent due, and perform and observe all other covenants
hereof, up to the time when possession is required for public use. However, if
only a part of said Premises shall be so taken and in the parties' mutual
judgment the Premises remain suitable for Tenant's continued use, and if two (2)
years or more of the Term hereof then remains unexpired, and if the remaining
Premises can be substantially restored within sixty (60) calendar days, then
this Lease shall not be terminated. Landlord will, at its expense, restore the
Premises. The rent payable by the Tenant during the period of restoration shall
be reduced by the apportioned amount. After such restoration, the rent herein
reserved shall be paid by Tenant as herein provided during the remainder of the
Term hereof abated by the percentage that the fair market value of the Premises,
attributable solely to the land and improvements, has been reduced because of
such taking. Said market value immediately before and after such taking shall be
determined by agreement of the parties or, failing agreement of the parties,
within thirty (30) calendar days of the effective date of such taking, by a
local independent fee appraiser selected by mutual agreement of Landlord and
Tenant, which appraiser's decision will be final and binding on the parties. The
cost of such appraiser shall be borne equally by Landlord and Tenant.

         Tenant shall have the right at its sole cost and expense to assert a
separate claim or join in Landlord's claim in any condemnation proceeding for
its personal property, its improvements, loss of value in its leasehold estate,
moving expenses, or any other claims it may have.

         Any dispute which arises under this Article regarding the usability of
the Premises after a taking and reasonable rent shall be settled by arbitration
pursuant and to the provisions of Article 28.

Article 21.       SECURITY DEPOSIT.

         Intentionally deleted.

Article 22.       financial statement:

         The persons signing this Lease on behalf of Tenant hereby personally
represent and warrant to Landlord that the financial statements delivered to
Landlord prior to the execution of this Lease properly reflect the true and
correct value of all the assets and liabilities of Tenant. Tenant acknowledges
that in entering into this Lease, Landlord is relying upon such statements, and
Tenant shall supply Landlord with updated financial statements of Tenant each
Lease Year as reasonably requested by Landlord.

Article 23.       guarantors:

         Intentionally deleted.

Article 24.       DEFAULT:

         a) Tenant shall fail to pay any installment of the rent or other
     charges hereby reserved and such failure shall continue for a period of ten
     (10) calendar days after due written notice to Tenant. Notwithstanding the
     above, if Tenant shall fail to pay any installment of rent or other charges
     by the dates set forth in this Lease more than twice in any calendar year,
     an event of default shall be deemed to have occurred without written notice
     from Landlord.

         b) Tenant shall fail to comply with any term, provision, or covenant
     of this Lease, other than the payment of rent, and shall not cure such
     failure within thirty (30) calendar days after due written notice thereof
     to Tenant, or, if such failure shall be of such a nature that the same
     cannot be completely cured within the said thirty (30) calendar days, if
     Tenant shall not have commenced to cure such failure within such thirty
     (30) day period and shall not thereafter with reasonable diligence and good
     faith proceed to cure such failure.

<PAGE>

         c) Tenant shall file a petition under any section or chapter of the
     National Bankruptcy Act, as amended, or under any similar law or statute of
     the United States or any state thereof, or an involuntary petition in
     bankruptcy shall be filed against Tenant thereunder.

         d) A receiver or trustee shall be appointed for all or substantially
     all of the assets of Tenant.

         e) Tenant shall abandon or vacate the Premises during the Term of this
     Lease.

         f) Tenant shall fail to occupy the leased Premises for fifteen (15)
     consecutive business days without prior written notice to Landlord of such
     vacancy.

         Upon the occurrence of any of such events of default, Landlord shall
have the right, at Landlord's election, to pursue, in addition to and cumulative
of any other rights Landlord may have at law or in equity, any one or more of
the following remedies without any notice or demand whatsoever:

              a) Terminate this Lease, in which event Tenant shall immediately
         surrender the Premises to Landlord, and if Tenant fails so to do,
         Landlord may, without prejudice to any other remedy which it may have
         for possession or arrearage in rent, enter upon and take possession of
         the Premises and expel or remove Tenant and any other person who may
         be occupying said Premises or any part thereof, without being liable
         for prosecution or any claim of damages therefor; and Tenant agrees to
         pay to Landlord on demand the amount of all loss and damage which
         Landlord may suffer by reason of such termination.

              b) Enter upon and take possession of the Premises and expel or
         remove Tenant and any other person who may be occupying the Premises
         or any part thereof without being liable for prosecution or any claim
         for damages therefor, and relet the Premises and receive the rent
         thereof; crediting Tenant therefor; and Tenant agrees to pay to
         Landlord on demand any deficiency that may arise by reason of such
         reletting.

              c) Enter upon the Premises without being liable for prosecution
         of any claim for damages therefor, and to do whatever Tenant is
         obligated to do under the Terms of this Lease, and Tenant agrees to
         reimburse Landlord on demand for any expense which Landlord may incur
         in thus effecting compliance with Tenant's obligations under the
         Lease, and Tenant further agrees that Landlord shall not be liable for
         any damages resulting to Tenant from such action, whether caused by
         the negligence of Landlord or otherwise.

              d) Require all rental payments by "subtenants", including within
         that term the third parties occupying various portions of the Premises
         under the terms of Lease agreements with Tenant, as primary lessor or
         as sublessor, which would otherwise be paid to Tenant to be paid
         directly to Landlord and apply such rentals so paid to or collected by
         Landlord against any rents or other charges due to Landlord by Tenant
         hereunder. No direct collection by Landlord from such "subtenants"
         shall release Tenant from the further performance of Tenant's
         obligations hereunder.

              e) Declare all unpaid rental payments for the Term or renewal
         term of this Lease to be due and payable immediately and proceed to
         collect the same.

         Pursuit of any of the foregoing remedies shall not preclude pursuit of
any of the other remedies herein provided or any other remedies provided by law
or equity, nor shall pursuit of any remedy herein provided constitute a
forfeiture or waiver of any rent due to Landlord hereunder or of any damages
accruing to Landlord by reason of the violation of any of the terms, provisions
and covenants herein contained. Failure by Landlord to enforce one or more of
the remedies herein provided upon an event of default shall not be deemed or
construed to constitute a waiver of such default or of any other violation or
breach of any of the terms, provisions and covenants herein contained.

         In determining the amount of loss or damage which Landlord suffers by
reason of the termination of this Lease Agreement or the amount of deficiency
arising by reason of the reletting by Landlord as provided above, damages shall
be awarded for Landlord's cost of repossessing the Premises and any and all
repairs or remodeling that is undertaken by Landlord to restore the Premises to
a tenantable condition or to place the Premises in a desirable tenantable
condition for a new tenant. These costs include reasonable attorney's fees and
court costs.

Article 26.       QUIET ENJOYMENT:

         Landlord hereby covenants and agrees that Tenant shall have the
peaceable possession and enjoyment of the Premises throughout the Term of this

Article 27.       SUBORDINATION AND NON-DISTURBANCE AND ESTOPPEL CERTIFICATE:

         This Lease and all of the rights of Tenant hereunder, except Tenant's
property or trade fixtures, shall be subject and subordinate to the lien of any
mortgage or mortgages now or hereinafter placed on the Premises or any part
thereof, and any and all renewals, modifications, replacements, extensions, or
substitutions of any such mortgage or mortgages, all of which are hereinafter
termed the "Mortgage" or "Mortgages". Tenant agrees to attorn to any receiver
appointed for the Property in connection with any Mortgage, to the holder of any
Mortgage (a "Mortgagee") who acquires possession of the Property, and to any
Mortgagee or other person who succeeds to the interest of Landlord under this
Lease or otherwise acquires title to the Property by foreclosure of a Mortgage

Tenant is not in default under this Lease Agreement, or any renewal thereof, no
foreclosure of the lien of said mortgage or any other proceeding with respect
thereof shall divest, impair, modify, abrogate or otherwise adversely affect any
interest or rights whatsoever of Tenant under this Lease Agreement. Tenant, if
requested by Landlord, shall execute any instruments in recordable form as may

reasonably requested by Landlord.

Article 28.       ARBITRATION:

         Any controversy, dispute, or claim arising out of or relating to:

         The usability of the Premises or reasonable rent after damage or
destruction as provided in Article 15, or

         The reasonableness of Landlord's consent or assignment or subletting as
provided in Article 19; or

         The usability of the Premises or reasonable rent after a taking as
provided in Article 20, shall be settled in arbitration in accordance with the
rules of the American Arbitration Association. The arbitration decision will be
final and binding upon the parties.

Article 29.       HOLD-OVER:

         In the event Tenant remains in possession of the Premises after the
expiration or earlier termination of this Lease, it shall operate and be
construed to be a tenancy from month-to-month only, at a monthly rental equal to
the rental paid for the last month of the Term of this Lease plus twenty percent
(20%) of such amount, unless otherwise agreed in writing, and otherwise subject
to the conditions, provisions and obligations of this Lease insofar as the same
are applicable to month-to-month tenancy.

ARTICLE 29A.      RIGHT OF FIRST REFUSAL:

     For a period of eighteen months following the Commencement Date, provided
Tenant is not in default of this Lease Agreement beyond any applicable cure
period, Tenant shall have the right of first refusal (the "Right of First
Refusal" or "ROFR") to lease all or part of the 43,500 SF located within the
building that is adjacent to the Premises (hereinafter referred to as the
"Additional Space"). The terms of the ROFR are as follows:

1.   In the event Landlord agrees to lease all or a portion of the Additional
     Space to another party subject to this ROFR, Landlord shall provide written
     notice to Tenant. Written notice will be provided to Tenant only after a
     proposal has been agreed upon by Landlord and the other party.

2.   Upon Tenant's receipt of notice by Landlord, Tenant shall have five (5)
     business days to notify the Landlord of Tenant's desire to exercise the
     ROFR. Landlord shall then furnish Tenant with a lease amendment stating the
     terms of leasing the Additional Space and adding the Additional Space to
     Tenant's lease. Such lease amendment shall include the same terms and
     conditions as this Lease Agreement and Landlord shall finish the Additional
     Space in the same manner as Tenant's warehouse space as described on the
     Exhibits G and H attached hereto. The Additional Space shall include
     lighting and climate control as provided in Exhibits G and H and two
     restrooms with two toilets/urinals in each. The costs for the improvements
     to the Additional Space comparable with those improvements described in the
     Scope of Work attached as Exhibit G -- Scope of Work shall be included in
     the Base Rent. The costs for the improvements to the Additional Space
     comparable with those improvements described in the Scope of Work attached
     as Exhibit H -- Additional TI Scope of Work shall be amortized, utilizing
     the same formula used for the TI Rent during the Initial Term, over the
     balance of the Lease Term or a new term shall be set forth that extends the
     Term of the Lease for the entire Premises including the Additional Space.

3.   Tenant shall have five (5) business days after receipt of the lease
     amendment to execute and deliver the amendment to Landlord in order for the
     ROFR to be exercised and enforceable by Tenant. In the event Tenant does
     not perform under the time periods contained herein, Landlord may enter
     into a Lease Agreement with another bona fide tenant for all or a portion
     of the Additional Space.

4.   If Tenant wishes to either (1) exercise the ROFR or (2) expand the Premises
     in an area other than the Additional Space, Landlord shall have the right,
     in Landlord's sole reasonable discretion, to determine the area available
     for such expansion. The available area for such

<PAGE>

     expansion shall be determined by Landlord based upon the balance of area
     available for lease in the Building, if any, after Tenant expands. The
     balance of leasable area within the Building must be of leasable size and
     deemed desirable by another tenant, in Landlord's sole reasonable
     discretion. Tenant acknowledges that the area of Additional Space or other
     expansion area within the Building available to Tenant may vary
     significantly from the 43,500 square feet for which Tenant enjoys a Right
     of First Refusal.

hereunder, such consent or approval shall not be unreasonably withheld.

         If any term, covenant, condition, or provisions of this Lease, or the
application thereof, to any person or circumstances, shall at any time or 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, covenant, condition, or provisions of this Lease shall
be valid and be enforced to the fullest extent permitted by law.

Article 33.       INTERPRETATION:

         Wherever in this Lease the singular number is used, the same shall
include the plural, and the masculine gender shall include the feminine and
neuter genders, and vice versa, as context shall require. The section headings
used herein are for reference and convenience only and shall not alter the
interpretation thereof. This Lease may be executed in several counterparts, each
of which shall be an original, but all of which shall constitute one and the
same instrument.

Article 34.       ENTIRE AGREEMENT:

         No oral statement or prior written agreement relating to this matter
shall have any force or effect. Tenant and Landlord agree that neither is
relying on any representations or agreements of the other except for those
contained in this Lease. This Lease shall not be modified or canceled except by
writing subscribed by all parties.

Article 35.       PARTIES:

         Except as otherwise expressly provided herein, the covenants,
