                                 GRANT AND TERM

      1.01 Grant of Lease. Landlord, for and in consideration of the rents
reserved herein and of the covenants and agreements contained herein on the part
of Tenant to be performed, hereby leases to Tenant, and Tenant hereby leases

and substitutions thereto from time to time are collectively referred to as the

      1.02 Term of Lease. The term hereof (the "Term") shall commence on April
11 , 2003 (the "Commencement Date") and shall expire on April 10 , 2018 (the
"Expiration Date"), unless earlier terminated or extended as provided in this

month, Tenant shall pay a proportionate amount of Base Rent in advance at the
monthly rate set forth herein for such partial month.

      1.03 Lease Year Defined. As used in this Lease, the term "Lease Year"
shall mean (i) if the Commencement Date is the first day of a calendar month,
the twelve (12) month period commencing on the Commencement Date or (ii) if the

                                    ARTICLE 2
                                    BASE RENT

month thereafter of the Term, and at the same rate for fractions of a month if

any day except the last day of a calendar month.

      2.02 Manner of Payment. Base Rent, Impositions (as defined below), and all
other amounts becoming due from Tenant to Landlord hereunder (hereinafter

States to Landlord at the office of Landlord, or as otherwise designated from
time to time by written notice from Landlord to Tenant.

      2.03 Net Lease. It is the intention of the parties hereto that the
obligations of Tenant hereunder shall be separate and independent covenants and
agreements, and that any Base Rent, Impositions, and other items of Rent and all
other sums payable by Tenant hereunder shall

<PAGE>

continue to be payable in all events, and that the obligations of Tenant
hereunder shall continue unaffected, unless the requirement to pay or perform
the same shall have been terminated pursuant to an express provision of this
Lease. This is a Net Lease and Base Rent, Impositions, and all other items of
Rent and all other sums payable hereunder by Tenant shall be paid without notice
or demand, and without setoff, counterclaim, recoupment, abatement, suspension,
deferment, diminution, deduction, reduction or defense, except as otherwise
specifically set forth herein. This Lease shall not terminate, and Tenant shall
not have any right to terminate this Lease, during the Term (except as otherwise
expressly provided herein). Tenant agrees that, except as otherwise expressly
provided herein, it shall not take any action to terminate, rescind or avoid
this Lease notwithstanding (i) bankruptcy, insolvency, reorganization,
composition, readjustment, liquidation, dissolution, winding-up or other
proceeding affecting Landlord, (ii) the exercise of any remedy, including
foreclosure, under any mortgage, (iii) any action with respect to this Lease
(including the disaffirmance hereof) which may be taken by Landlord under the
Federal Bankruptcy Code or otherwise, (iv) the taking of the Premises or any
portion thereof (except as specifically provided in Article 15 hereof), (v) the
prohibition or restriction of Tenant's use of the Premises under any laws or
otherwise, (vi) the destruction of the Premises or any portion thereof, or (vii)
the eviction of Tenant from possession of the Premises, by paramount title or
otherwise, (viii) default by Landlord hereunder or under any other agreement
between Landlord and Tenant. Except as expressly permitted in this Lease, and
subject to any right conferred by law of Tenant to receive notice, Tenant waives
all rights which are not expressly stated herein which may now or hereafter
otherwise be conferred by law to quit, terminate or surrender this Lease or any
of the Premises; to any setoff, counterclaim, recoupment, abatement, suspension,
deferment, diminution, deduction, reduction or defense of or to Base Rent,
Impositions, or other items of Rent or any other sums payable under this Lease,
except as otherwise expressly provided herein; and for any statutory lien or
offset right against Landlord or its property. Landlord and Tenant agree that
this Lease is a true lease and does not represent a financing agreement. Each
party shall reflect the transaction represented hereby in all applicable books,
records and reports (including income tax filings) in a manner consistent with
"true lease" treatment rather than "financing" treatment.

                                    ARTICLE 3
                                   IMPOSITIONS

      3.01 Tenant to Pay Impositions. Tenant shall pay or cause to be paid, in a
timely manner and as hereinafter provided, all of the following items, if any,
("Impositions"): (a) real property taxes and assessments with respect to the
Premises or any portion thereof; (b) Tenant's personal property taxes; (c)
occupancy and rent taxes specifically assessed against the Premises and/or
Tenant; (d) water, water meter and sewer rents, rates and charges; (e) license
and permit fees related to Tenant's use or occupancy of the Premises; (f)
service charges, with respect to police protection, fire protection, street and
highway maintenance, construction and lighting, sanitation and water supply, if
any; (g) taxes imposed or levied upon or assessed against the Premises, or
Landlord as the owner of the Premises, to the extent such taxes are measured by
Base Rent or other Rent payable hereunder, but only to the extent that such
taxes would be payable if the Premises were the only property of Landlord; (h)
intentionally omitted; (j) payments in lieu of each of the foregoing, whether or
not expressly so designated; (k) fines, penalties and other similar or like
governmental charges applicable to any of the foregoing and any interest or
costs with respect thereto to the extent not caused by Landlord's negligent act
or omission; and (l) any and all other federal, state, county and municipal
governmental and quasi-governmental levies, fees, rents, assessments or taxes
and charges, general and special, ordinary and extraordinary, foreseen and
unforeseen, of every kind and nature whatsoever, and any interest or costs with
respect thereto, which at any time during, prior to or after (but attributable
to a period falling within) the Term are (1) assessed, levied,

                                                                               2
<PAGE>

confirmed, imposed upon, or would grow or become due and payable out of or in
respect of, or would be charged with respect to, Tenant's use and occupancy of
the Premises or any document to which Tenant is a party creating or transferring
an interest or estate in the Premises or this transaction, and/or (2)
encumbrances or liens on Tenant's use and occupancy of (i) the Premises; (ii)
any other appurtenances of the Premises; (iii) any personal property, equipment
serving the Building or other facility used in the operation thereof; or (iv)
the Base Rent or other Rent (or any portion thereof) payable by Tenant
hereunder. Each such Imposition, or installment thereof, during the Term shall
be paid before the last day the same may be paid without fine, penalty, interest
or additional cost.

      Notwithstanding anything contained in the foregoing to the contrary,
Landlord may, if from time to time required by Landlord's mortgagee, reasonably
estimate in advance the amounts Tenant shall owe for real property taxes and
assessments for any full or partial calendar year of the Term. In such event,
Tenant shall pay to Landlord's mortgagee 1/12th of such estimated amounts, on a
monthly basis, on or before the first day of each calendar month. Tenant shall
pay such estimated amounts to Landlord's mortgagee at the time Tenant pays its
monthly installments Base Rent to Landlord. Such estimate may be reasonably
adjusted from time to time by Landlord. If Landlord shall have Tenant pay such
taxes on a monthly basis in accordance with this paragraph, the following shall
apply:

            (a) Within one hundred twenty (120) days after the end of each
calendar year, or as soon thereafter as practicable, Landlord shall provide a
statement (the Statement") to Tenant showing: (1) the amount of actual taxes for
such calendar year, (2) any amount paid by Tenant towards taxes during such
calendar year on an estimated basis, and (3) any revised estimate of Tenant's
obligations for taxes for the current calendar year.

            (b) If the Statement shows that Tenant's estimated payments were
less than Tenant's actual obligations for taxes for such year, Tenant shall pay
the difference. If the Statement shows an increase in Tenant's estimated
payments for the current calendar year, Tenant shall pay the difference between
the new and former estimates, for the period from January 1 of the current
calendar year through the month in which the Statement is sent. Tenant shall
make such payments within thirty (30) days after Landlord sends the Statement.
Tenant's obligations to make the foregoing payments shall survive the expiration
or earlier termination of this Lease.

            (c) If the Statement shows that Tenant's estimated payments exceeded
Tenant's actual obligations for taxes, Tenant shall receive a credit for the
difference against payments of Impositions next due. If the Term shall have
expired and no further Impositions shall be due, Tenant shall receive a refund
of such difference, within thirty (30) days after Landlord sends the Statement.

            (d) Landlord reserves the right to reasonably change, from time to
time, the manner or timing of the foregoing payments. In lieu of providing one
Statement covering taxes, Landlord may provide separate statements, at the same
or different times. No delay by Landlord in providing the Statement (or separate
statements) shall be deemed a default by Landlord or a waiver of Landlord's
right to require payment of Tenant's obligations for actual or estimated taxes.

            (e) Any special assessments shall be paid over the maximum number of
installments permitted by the taxing authority, and only those being assessed
against the Premises during the Term must be paid by Tenant.

                                                                               3
<PAGE>

      3.02 Receipt of Payment. Tenant, from time to time upon request of
Landlord, shall furnish to Landlord, within the earlier of (i) thirty (30) days
after the date when an Imposition is due and payable under this Lease, or (ii)
thirty (30) days after the date when an official receipt of the appropriate
imposing authority is received, such official receipt or, if no such receipt has
been received by Tenant, other evidence reasonably satisfactory to Landlord
evidencing the payment of the Imposition.

      3.03 Exclusions.

            (a) Except as provided in subparagraph (b) hereinbelow, nothing
contained in this Article 3 shall require Tenant to pay state or federal income,
inheritance, estate, succession, capital levy, stamp, excess profit, revenue,
business activities (such as the Michigan Single Business Tax) or gift taxes of
Landlord, or any corporate franchise tax imposed upon Landlord, or any other tax
imposed against Landlord generally and not specifically related to Landlord's
ownership of the Building or the Premises or the receipt of rents from the
Premises.

            (b) If at any time during the Term, a tax or excise on Base Rent or
other Rent or the right to receive rents or other tax, however described, is
levied or assessed against Landlord as a substitute in whole or in part for any
Impositions theretofore payable by Tenant, Tenant shall pay and discharge such
tax or excise on Rental or other tax before interest or penalties accrue, and
the same shall be deemed to be an Imposition levied against the Premises.

      3.04 Fiscal Periods. Any Imposition imposed against the Premises, relating
to a fiscal period of the imposing authority, a part of which period is included
within the Term and a part of which is included in a period of time after the
date definitely fixed in Article 1 hereof for the expiration of the Term
(whether or not such Imposition shall be assessed, levied, confirmed, imposed
upon or in respect of or become a lien upon the Premises, or shall become
payable, during the Term) shall be apportioned between Landlord and Tenant as of
such date definitely fixed for the expiration of the Term, so that Tenant shall
pay that portion of such Imposition which that part of such fiscal period
included in the period of time before such date definitely fixed for the
expiration of the Term bears to the entirety of such fiscal period, and Landlord
shall pay the remainder thereof. The foregoing obligations shall survive
expiration or termination of the Term.

      3.05 Contest. Tenant shall have the right to contest the amount or
validity, in whole or in part, of any Imposition by appropriate proceedings
diligently conducted in good faith, but only after payment of such Imposition,
unless such payment would operate as a bar to such contest, in which event,
notwithstanding the provisions of Section 3.01 hereof, payment of such
Imposition shall be postponed if and only as long as:

            (a) neither the Premises nor any part thereof would, by reason of
such postponement or deferment, be, in the reasonable judgment of Landlord, in
danger of being forfeited, lost or adversely affected;

            (b) such contest shall not subject Landlord or any Mortgagee (as
hereinafter defined) to the risk of any criminal or civil liability;

            (c) such contest shall not cause Landlord to be in default under any
Mortgage (as hereinafter defined);

                                                                               4
<PAGE>

            (d) such contest shall not, in the reasonable judgment of Landlord,
result in any Imposition being increased; and

            (e) Tenant shall have deposited with, at Landlord's option, either
Landlord or a Depositary (as hereinafter defined), simultaneously with such
contest, cash or other security determined by Landlord in the amount so
contested and unpaid, together with all interest and penalties in connection
therewith and all charges that may be assessed against or become a charge on the
Premises or any part thereof in such proceedings.

      Upon the termination of such proceedings, it shall be the obligation of
Tenant to pay the amount of such Imposition or part thereof as finally
determined in such proceedings, the payment of which may have been deferred
during the prosecution of such proceedings, together with any costs, fees
(including attorneys' fees and disbursements), interest, penalties or other
liabilities in connection therewith, and upon such payment, Landlord or
Depositary, as the case may be, shall return, with any interest accrued thereon,
any amount deposited with it in respect of such Imposition as aforesaid,
provided, however, that Landlord or Depositary, as the case may be, if requested
by Tenant, shall disburse said moneys on deposit with it directly to the
imposing authority to whom such Imposition is payable. If, at any time during
the continuance of such proceedings, Landlord shall reasonably deem the amount
deposited as aforesaid insufficient, Tenant, upon demand, shall make an
additional deposit of such additional sums or other acceptable security as
Landlord may request, and upon failure of Tenant to do so, the amount
theretofore deposited may, at the option of Landlord, be applied by Landlord or
Depositary, as the case may be, to the payment, removal and discharge of such
Imposition and the interest and penalties in connection therewith and any costs,
fees (including attorneys' fees and disbursements) or other liability accruing
in any such proceedings, and the balance, if any, shall be returned to Tenant or
the deficiency, if any, shall be paid by Tenant on demand.

      3.06 Reduction of Assessed Valuation. Subject to the provisions of Section
3.05, Tenant shall have the right to seek a reduction in the assessed valuation
of the Premises for real property tax purposes and to prosecute any action or
proceeding in connection therewith.

      3.07 Joinder of Landlord. Landlord shall not be required to join in any
proceedings referred to in Sections 3.05 or 3.06 hereof unless the provisions of
any law, rule or regulation at the time in effect shall require that such
proceedings be brought by and/or in the name of Landlord, in which event,
Landlord shall join and cooperate in such proceedings or permit the same to be
brought in its name but shall not be liable for the payment of any costs or
expenses in connection with any such proceedings, and Tenant shall reimburse and
indemnify Landlord for any and all costs or expenses which Landlord may sustain
or incur in connection with any such proceedings.

      3.08 Evidence of Imposition. Any certificate, advice or bill of the
appropriate official designated by law to make or issue the same or to receive
payment of any Imposition asserting nonpayment of such Imposition shall be prima
facie evidence that such Imposition is due and unpaid at the time of the making
or issuance of such certificate, advice or bill.

                                       USE

      4.01 Use of Premises. Tenant shall use and occupy the Premises only for
office, storage and light industrial purposes as permitted by the applicable
zoning for the Premises, and for no other use or purpose.

                                                                               5

                                    UTILITIES

      5.01 Payment for Utilities. During the Term, Tenant will pay, when due,
all charges of every nature, kind or description for utilities furnished to the
Premises or chargeable against the Premises, including all charges for water,
sewage, heat, gas, light, garbage, electricity, telephone, steam, power, or
other public or private utility services. Prior to commencement of the Term,
Tenant shall pay for all utilities or services at the Premises used by it or its
agents, employees or contractors.

      5.02 Utilities. Tenant shall be responsible for contracting directly with
all suppliers of utility services. In the event that any charge or fee is
required by the State of Michigan, or by any agency, subdivision or
instrumentality thereof, or by any utility company or other entity furnishing
services or utilities to the Premises, as a condition precedent to furnishing or
continuing to furnish utilities or services to the Premises, such charge or fee
shall be deemed to be a utility charge payable by Tenant. The provisions of this
paragraph shall include, but shall not be limited to, any charges or fees for
present or future water or sewer capacity to serve the Premises, any charges for
the underground installation of gas or other utilities or services, and other
charges relating to the extension of or change in the facilities necessary to
provide the Premises with adequate utility services. Tenant may elect to cause
the separate metering of utilities to various portions of the Building. If
Tenant makes such an election, the costs of such separate metering shall be at
the sole and exclusive cost of Tenant. In the event Tenant fails to pay any such
charge or fee contemplated by this Section 5.02, Landlord shall have the right,
but not the obligation, to pay such charge or fee on Tenant's behalf, whereupon
Tenant shall reimburse Landlord for such utility charge upon Landlord's demand
therefore at the default rate of interest on all amounts owed until paid. The
inability of Tenant to obtain, or any stoppage of, the utility services referred
to in this Article 5 resulting from any cause shall not make Landlord liable in
any respect for damages to any person, property or business, or entitle Tenant
to any abatement of Rent or other relief from any of Tenants obligations under
this Lease.

                                    INSURANCE

      6.01 Tenant's Insurance.

          (a) Tenant shall:

              (i) keep the Building and the Improvements insured against loss or
damage by fire, windstorm, tornado and hail and all other hazards customarily
included in the standard "all risk" coverage from, as may be commercially
available from time to time ("Casualty Insurance"), including, without
limitation, coverage for loss or damage by water, flood, sprinkler leakage,
boiler explosions or similar occurrences, subsidence and earthquake, with such
sublimits as are reasonably required by Landlord and consistent with those
sublimits from time to time customarily carried for properties located in or
near Kentwood, Michigan comparable to the Premises in use, size and age, and
excluding from such coverage loss or damage due to the normal settling of the
Premises. Such coverage shall include losses from war risks and acts or
terrorism when and to the extent obtainable from the United States government or
an agency thereof so long as the annual cost for coverage with respect to such
risks does not exceed ten percent (10%) of the annual cost for the "all risk"
coverage required pursuant to this Section 6.01(a). Such Casualty Insurance
shall be in the amount set forth in the "agreed amount clause" endorsement to
the policy in question, which endorsement shall be attached to the policy,
provided that such amount, in all events, shall be (x) sufficient to prevent
Landlord and Tenant

                                                                               6
<PAGE>

from becoming co-insurers under provisions of applicable policies of insurance,
and (y) in the amount not less than one hundred percent (100%) of the Net
Replacement Cost of the Building, such Net Replacement Cost to be determined by
the insurers from time to time, but not less frequently than required by the
standard "agreed amount clause" endorsement, and no omission on the part of
Landlord to request any such determination shall relieve Tenant of its
obligation to have such Net Replacement Cost determined as aforesaid;

                  (ii)  provide and keep in force general comprehensive public
liability insurance ("Liability Insurance") against liability for bodily injury
and death and property damage, such Liability Insurance to be in such amount as
may from time to time be reasonably required by Landlord and consistent with
that carried for properties similar to the Premises in use, size and age, but
not less than $3,000,000 combined single limit for liability for bodily injury,
death and property damage, and shall include the Premises and all sidewalks
adjoining or appurtenant to the Premises, shall contain blanket contractual
coverage and shall also provide the following protection:

                        (1) personal injury protection;

                        (2) fire legal liability, if not otherwise covered under
the comprehensive form of public liability insurance;

                        (3) employees as additional insured coverage; and

                        (4) Blanket Contractual Liability coverage; which
coverage shall contain an endorsement that (x) names Landlord as an additional
insured, (y) specifically references the Premises; and (z) guarantees a minimum
limit available for the Premises equal to the insurance amount required in this
Lease.

If applicable, Tenant also shall provide and keep in force automobile liability
and property damage insurance for all owned, non-owned and hired vehicles
insuring against liability for bodily injury and death and for property damage
in an amount determined from time to time by Landlord, but not less than
$3,000,000 combined single limit, such insurance to contain the so-called
"occurrence clause";

                  (iii) provide and keep in force workers' compensation and
occupational disease providing statutory benefits for all persons employed by
Tenant at or in connection with the Premises;

                  (iv) provide and keep in force rent insurance on an "All Risk
of Physical Loss" basis in an amount not less than the sum of (a) the Base Rent
then payable hereunder for a period of one (1) year, (b) an amount equal to the
Impositions for a like period, and (c) an amount equal to the insurance premiums
payable under this Lease for a like period;

                  (v) provide and keep in force boiler, machinery and pressure
vessel insurance in an amount determined from time to time by Landlord, but not
less than $3,000,000 per occurrence on a combined basis covering direct property
loss and loss of income and providing for all steam, mechanical and electrical
equipment, including, without limitation, all boilers, unfired pressure vessels,
piping and wiring.

            (b) Whenever, under the terms of this Lease, Tenant is required to
maintain insurance, Landlord shall be an additional named insured and loss
payee, as its interests may appear in all such insurance policies other than (i)
business interruption policies, (ii) worker's

                                                                               7
<PAGE>

compensation insurance, and (iii) insurance in connection with automobile
liability and property damage for all vehicles used in connection with the
Premises. If the Premises shall be subject to any Mortgage, the public liability
insurance shall, if required by such Mortgage, name the Mortgagee as an
additional named insured, and all other insurance provided hereunder shall name
the Mortgagee as an additional named insured under a standard "noncontributory
mortgagee" endorsement or its equivalent.

      6.02 Payment of Losses.

            (a) The loss under all policies required by any provision of this
Lease insuring against damage to the Building by fire or other casualty shall be
payable:

                (i) to Tenant, as trustee, if the amount thereof is less than
$100,000, or

                (ii) to Depositary, if the amount thereof is $100,000 or more.

If a loss shall be payable to Tenant, as trustee, Tenant, provided that there is
no Default by Tenant hereunder, (1) shall hold the insurance proceeds with
respect to such loss in trust for the sole purpose of paying the cost of the
Restoration, and (2) shall apply such proceeds first to the payment in full of
the cost of the Restoration before using any part of the same for any other
purpose. Tenant shall give Landlord notice of completion of the Restoration
within ten (10) days thereafter. If Landlord makes no claim or objection with
respect to such proceeds or their disposition within ninety (90) days after such
notice is given, then Tenant may pay over to itself the unapplied proceeds and
the trust obligations hereunder with respect to such proceeds shall terminate.
Notwithstanding the foregoing, if there is a Default by Tenant hereunder, Tenant
shall pay (or assign) all insurance proceeds with respect to such loss to
Landlord.

            (b) All Insurance Policies shall be in such form and shall be issued
by such responsible companies licensed and authorized to do business in the
State of Michigan as are reasonably acceptable to Landlord. All such companies
shall have a policyholder rating of not less than A and be assigned a financial
size category of no less than X as rated in the most recent edition of Best's
Key Rating Guide for insurance companies (or if Best's ceases to be published)
in a similar rating guide acceptable to Landlord. All policies referred to in
this Lease shall be procured, or caused to be procured, by Tenant, at no expense
to Landlord, and for periods of not less than one (1) year. A photocopy of each
such policy, certified by the insurer to be a true copy thereof, shall be
delivered to Landlord immediately upon request by Landlord. In addition thereto,
Tenant shall deliver to Landlord certificates of the insurance required
hereunder together with paid receipts therefor. Certificates of new or renewal
insurance replacing any insurance expiring during the Term shall be delivered as
aforesaid at least fifteen (15) days before the date of expiration, together
with proof satisfactory to Landlord that the full premiums have been paid for at
least the first year of the term of such policies. During the term of such
policies, at least fifteen (15) days before each anniversary of the effective
date of the policy, Tenant shall deliver to Landlord proof satisfactory to
Landlord that the full premiums have been paid for at least the next year of the
term of the policy. Premiums on policies shall not be financed in any manner
whereby the lender, on default or otherwise, shall have the right or privilege
of surrendering or canceling or requesting the surrender or cancellation of the
policies, provided, however, that premiums may be paid in such installments as
are permitted pursuant to the provisions of the applicable policy so long as
payment by installments will not allow the insurer thereunder to cancel said
policy without notice to the insureds.

            (c) Tenant and Landlord shall cooperate in connection with the
collection of any insurance moneys that may be due in the event of loss, and
Tenant and Landlord shall

                                                                               8
<PAGE>

execute and deliver such proofs of loss and other instruments which may be
required for the purpose of obtaining the recovery of any such insurance moneys.

            (d) Tenant shall not carry separate insurance concurrent in form or
contributing in the event of loss with that required by this Lease to be
furnished by Tenant, unless Landlord and each Mortgagee is included therein as
additional named insureds with any loss payable as provided in this Lease.
Tenant shall immediately notify Landlord of the carrying of any such separate
insurance and shall cause the same to be delivered as required in this Lease.

            (e) Tenant shall not violate or permit to be violated any of the
conditions or provisions of any of the Insurance Policies, and Tenant shall so
perform and satisfy or cause to be performed and satisfied the requirements of
the companies writing such policies so that at all times companies of good
standing, satisfactory to Landlord (as provided in Section 6.02(b) hereof),
shall be willing to write and continue such insurance.

            (f) Each Insurance Policy and each certificate or memorandum
therefor issued by the insurer shall contain, as applicable (i) a provision that
no act or omission of Tenant shall affect or limit the obligation of the insurer
to pay Landlord or any Mortgagee the amount of any loss sustained, (ii) an
agreement by the insurer that such policy shall not be cancelled or modified
without at least thirty (30) days' prior written notice to Landlord and each
Mortgagee, and (iii) a waiver of subrogation by the Insurer of any right to
recover the amount of any loss resulting from the negligence of Landlord or its
agents, employees or licensees to the extent of available Landlord's insurance.

            (g) Landlord shall not be limited in the proof of any damages which
Landlord may claim against Tenant arising out of or by reason of Tenant's
failure to provide and keep in force insurance, as aforesaid, to the amount of
the insurance premium or premiums not paid or incurred by Tenant and which would
have been payable under such insurance, but Landlord shall also be entitled to
recover as damages for such breach the uninsured amount of any loss, to the
extent of any deficiency in the insurance required by the provisions of this
Lease, and damages, costs and expenses of suit suffered or incurred by reason of
damage to, or destruction of, the Premises occurring during any period when
Tenant shall have failed or neglected to provide insurance as aforesaid.

            (h) Each of Landlord and Tenant hereby waives any and every claim
for recovery from the other for any and all loss or damage to the Land or the
Building or to the contents thereof, whether such loss or damage is due to the
negligence of Landlord or Tenant or their respective agents or employees, which
loss or damage is insured pursuant to this Lease by valid and collectible
insurance policies and then only to the extent of the proceeds collected or
collectible under such insurance policies; provided, however, that the foregoing
waiver shall not be operative in any case where the effect thereof is to
invalidate any insurance coverage of the waiving party or increase the cost of
such insurance coverage; provided further, that Landlord and Tenant each agree
to give written notice of the terms of this mutual waiver to each insurance
company which has issued, or in the future may issue, policies of physical
damage to it, and to have said insurance policies properly endorsed to prevent
the invalidation of said insurance coverage by reason of said waiver and
provided further that such insurance company waives all rights of subrogation
which it might have against Landlord or Tenant, as the case may be.

      6.03 Blanket or Umbrella Policy. The insurance required by this Lease, at
the option of Tenant, may be effected by blanket and/or umbrella policies issued
to Tenant covering the Premises and other properties owned or leased by Tenant,
provided that the policies otherwise comply with the provisions of this Lease
and allocate to the Premises the specified coverage,

                                                                               9
<PAGE>

without possibility of reduction or coinsurance by reason of, or damage to, any
other premises covered therein.

      6.04 Loss Deductibles. As of the date hereof, Tenant's current loss
deductibles are $1,000,000. Notwithstanding the foregoing to the contrary,
Tenant shall reduce its loss deductibles to comply with the requirements from
time to time of Landlord's mortgagees so long as such requirements permit loss
deductibles of not less than $100,000. Notwithstanding the immediately preceding
sentence, all insurance provided for under Section 6.01 may contain loss
deductible clauses in such amounts as Landlord from time to time reasonably
shall approve, except that Landlord shall not require that Tenant carry loss
deductibles less than the loss deductibles then being carried for properties
located in or near Kentwood, Michigan similar to the Premises in use, size and
age.

      6.05 Definition of "Depositary". As used in this Lease, "Depository" shall
mean a savings bank, a savings and loan association, a commercial bank or trust
company (whether acting individually or in a fiduciary capacity), a pension or
retirement fund, an insurance company organized and existing under the laws of
the United States or any state thereof, a real estate investment trust existing
in compliance with Sections 856 through 860 of the Internal Revenue Code of
1986, as amended; provided, that each of the above entities shall qualify as
Depositary within the provisions of this definition only if it shall be
qualified to do business in the State of Michigan and has assets of not less
than $50 million.

                               RETURN OF PREMISES

      7.01 Surrender of Possession. At the termination of this Lease by lapse of
time or otherwise, or upon termination of Tenant's right of possession without
termination of this Lease, Tenant shall surrender possession of the Premises to
Landlord and deliver all keys to the Premises to Landlord and make known to
Landlord the combination of all locks of vaults then remaining in the Premises,
and, subject to the following paragraph, shall return the Premises and fixtures
therein to Landlord in as good condition as when Tenant originally took
possession reasonable wear and tear excepted, failing which Landlord may restore
the Premises and such equipment and fixtures to such condition and Tenant shall
pay the cost thereof to Landlord on demand.

      7.02 Installations and Additions. All additions, partitions, light
fixtures, fixtures, whether placed there by Tenant or Landlord (other than of
the type specifically excluded by Exhibit A) and Improvements, whether temporary
or permanent, shall be Landlord's property and shall remain upon the Premises,
all without compensation, allowance or credit to Tenant; provided, however, that
if prior to such termination or within ten (10) days thereafter Landlord so
directs by notice, Tenant, at Tenant's sole cost and expense, shall promptly
remove such of the additions, partitions, light fixtures, fixtures and
Improvements placed in the Premises by Tenant as are designated in such notice
and repair any damage to the Premises caused by such removal, failing which
Landlord may remove the same and repair the Premises and Tenant shall pay the
cost thereof to Landlord on demand, unless Landlord, at the time Tenant requests
Landlord's consent for the installation of the Improvements, advises Tenant in
writing that, upon expiration or earlier termination of this Lease, Tenant shall
not be obligated to remove such Improvements. At the sole option of Landlord,
Tenant shall leave in place any floor covering without compensation to Tenant,
or Tenant shall remove any floor covering, other than factory floor coatings
bonded to such floor, and shall remove all fastenings, paper, glue, bases or
other vestiges and restore the floor surface to its previous condition, or shall
pay to Landlord upon demand the cost for restoring the floor surface to such
condition.

                                                                              10
<PAGE>

      7.03 Trade Fixtures and Personal Property. Tenant also shall remove
Tenant's furniture, machinery, safes, trade fixtures and other items of movable
personal property of every kind and description from the Premises and restore
any damage to the Premises caused thereby, such removal and restoration to be
performed prior to the end of the Term or within ten (10) days following
termination of this Lease or Tenant's right of possession, whichever is earlier.
If Tenant fails to remove such items, Landlord may do so and thereupon the
provisions of Section 16.06 shall apply and Tenant shall pay to Landlord upon
demand the cost of removal and of restoring the Premises.

      7.04 Survival. All obligations of Tenant under this Article shall survive
the expiration of the Term or earlier termination of this Lease.

                                   ARTICLE 8
                                  HOLDING OVER

      Unless Landlord expressly agrees otherwise in writing, Tenant shall pay
Landlord two hundred percent (200%) of the amount of the Base Rent then
applicable to the final Lease Year of the Term (or the highest amount permitted
by law, whichever shall be less) prorated on a per diem basis for each day
Tenant shall retain possession of the Premises or any part thereof after
expiration or earlier termination of this Lease, together with all damages,
consequential and otherwise, sustained by Landlord on account thereof. The
foregoing provisions shall not serve as permission for Tenant to hold-over, nor
serve to extend the Term (although Tenant shall remain bound to comply with all
provisions of this Lease until Tenant vacates the Premises, and shall be subject
to the provisions of Article 7). Notwithstanding the foregoing to the contrary,
at any time before or after expiration or earlier termination of this Lease,
Landlord may serve notice advising Tenant of the amount of the Base Rental and
other terms required, should Tenant desire to enter a month-to-month tenancy
(and if Tenant shall hold over more than one full calendar month after such
notice, Tenant shall thereafter be deemed a month-to-month tenant, on the terms
and provisions of this Lease then in effect, as modified by Landlord's notice,
and except that Tenant shall not be entitled to any renewal rights contained in
this Lease or any amendments hereto).

                                   ARTICLE 9
                         CONDITION AND CARE OF PREMISES

      9.01 As-Is Condition. Tenant acknowledges and agrees that except as may
otherwise be specifically provided herein, Tenant accepts the Premises and the
Building in "as-is" condition and agrees that Landlord makes no representation
or warranty as to the condition thereof.

      9.02 Tenant's Obligations. Tenant shall take good care of the Premises,
Building, Building fixtures, and the Improvements, including, without limiting
the generality of the foregoing, roofs, foundations and appurtenances thereto,
all mechanical, electrical, plumbing, and heating, air-conditioning and
ventilation systems located in or otherwise serving the Building, all sidewalks,
vaults, sidewalk hoists and curbs in front of or adjacent to the Premises, and
all water, sewer and gas connections, pipes and mains which service the Premises
and which neither any public authority nor a utility company is obligated to
repair and maintain, and shall put, keep and maintain the Building and the other
Improvements in good and safe order and working condition, and make all repairs
therein and thereon, interior and exterior, structural and nonstructural,
ordinary and extraordinary, foreseen and unforeseen, necessary to keep the same
in good and safe order and working condition and to comply with all applicable
laws, howsoever the necessity or desirability therefor may occur, and whether or
not necessitated by wear and tear, obsolescence or defects, latent or otherwise.
The necessity and adequacy of repairs made shall

                                                                              11

be measured by standards which are appropriate for buildings of similar age,
construction and use. Tenant shall not commit or suffer, and shall use all
reasonable precaution to prevent, waste, damage or injury to the Premises. When
used in this Lease, the term "repairs" shall include all alterations, additions,
installations, replacements, removals, renewals and restorations. All repairs
made by Tenant shall be at least equal in quality and class to the original work
and shall be made in compliance with all Requirements, as then in force.

      9.03 Landlord Not Obligated. Landlord shall not be required to furnish any
services, utilities or facilities whatsoever to the Premises, nor shall Landlord
have any duty or obligation to make any alteration, change, improvement,
replacement, restoration or repair to, or to demolish, the Building or any other
Improvement presently or hereafter located on the Land. Tenant assumes the full
and sole responsibility for the condition, operation, repair, alteration,
improvement, replacement, maintenance and management of the Premises, including
any Building or any other Improvement.

                           RIGHTS RESERVED TO LANDLORD

      10.01 Rights Reserved to Landlord. Landlord reserves the following rights,
exercisable without liability to Tenant for damage or injury to property, person
or business and without effecting an eviction or disturbance of Tenant's use or
possession or giving rise to any claim for setoff or abatement of Rent or
affecting any of Tenant's obligations under this Lease and, except in the event
an emergency which represents a hazard to persons or property, with reasonable
prior notice and when inside the Building, accompanied at all times by a
representative of Tenant:

            (a) To exhibit the Premises at reasonable hours, subject to Tenant's
reasonable restrictions if the Premises are being exhibited to anyone involved
with, or associated with, a business that competes with Tenant's business;

            (b) To decorate, remodel, repair, alter or otherwise prepare the
Premises for reoccupancy at any time after Tenant vacates or abandons the
Premises;

            (c) To enter the Premises at reasonable hours for reasonable
purposes, including inspection, with reasonable prior notice and accompanied at
all times by a representative of Tenant, except in the event of an emergency;
and

            (d) To make any repairs in and about the Building.

The foregoing right of Landlord to have access to the Premises shall be subject
to reasonable restrictions imposed by Tenant to protect Tenant against entry
onto the Premises by Tenant's business competitors.

                                   ALTERATIONS

      Tenant shall not make, without the prior written consent of Landlord, any
alterations, additions or improvements to the Premises; provided, however,
Landlord's prior consent shall not be required if such alteration (i) is a
non-structural alteration which does not affect any systems of the Building and
(ii) will cost, for any one such alteration, less than $50,000. Landlord shall
not unreasonably withhold such consent, and Landlord shall be deemed to have
consented to any request by Tenant for a consent, if Landlord does not respond
to such request within fourteen (14) days thereafter, provided that Tenant shall
have first furnished to Landlord for approval plans and specifications, names
and addresses of contractors, copies of contracts, and instruments of

                                                                              12
<PAGE>

indemnification against any and all claims, costs, expenses, damages and
liabilities which may arise in connection with such work, all in such form,
substance and amount as may be satisfactory to Landlord. In addition, prior to
commencement of any such work or delivery of any materials into the Premises,
Tenant shall provide Landlord with necessary permits and licenses and
appropriate evidence of Tenant's ability to pay for such work and materials in
full, and if requested by Landlord, shall deposit with Landlord at such time
such security for the payment of said work and materials as Landlord may
require. All alterations, additions and improvements shall be installed in a
good, workmanlike manner and only new, high-grade materials shall be used.
Tenant further agrees to hold Landlord harmless from any and all liabilities of
every kind and description which may arise out of or be connected in any way
with said alterations, additions or improvements. Before commencing any work in
connection with such alterations, additions or improvements, Tenant shall
furnish Landlord with certificates of insurance from all contractors performing
labor or furnishing materials insuring Landlord against any and all liabilities
which may arise out of or may be connected in any way with said alterations,
additions or improvements. Tenant shall permit Landlord to supervise
construction operations in connection with the foregoing work if Landlord
requests to do so. Tenant shall pay the cost of all such alterations, additions
and improvements, as well as the cost of decorating the Premises occasioned by
such alterations, additions and improvements, including the cost of labor and
materials. Upon completing any alterations, additions or improvements, Tenant
shall furnish Landlord with contractors' affidavits in form required by law, and
full and final waivers of lien and receipted bills covering all labor and
materials expended and used. All alterations, additions and improvements shall
comply with all insurance requirements and with all city and county ordinances
and regulations and with the requirements of all state and federal statutes and
regulations.

                            ASSIGNMENT AND SUBLETTING

      12.01 Assignment and Subletting. Without the prior written consent of
Landlord in each instance, Tenant shall not (a) assign, transfer, mortgage,
pledge, hypothecate or encumber or subject to or permit to exist upon or be
subjected to any lien or charge, this Lease or any interest under it; (b) allow
to exist or to occur any transfer of or lien upon this Lease or Tenant's
interest herein by operation of law; (c) sublet the Premises or any part
thereof; or (d) permit the use or occupancy of the Premises or any part thereof
for any purpose not provided for under Article 4 of this Lease or by anyone
other than Tenant, Tenant's employees and any Tenant Successor (as hereinafter
defined) that has a net worth (including intangible net worth) equal to or
greater than the net worth of the original Tenant as of the date of this Lease
or the date of such assignment or sublet, whichever is greater. Landlord has the
absolute right to withhold its consent as provided in Section 12.05 below. In no
event shall this Lease be assigned or assignable by voluntary or involuntary
bankruptcy proceedings or otherwise, and in no event shall this Lease or any
rights or privileges hereunder be an asset of Tenant under any bankruptcy,
insolvency or reorganization proceedings. As used herein, the term "Tenant
Successor" shall mean any entity (y) which results from a merger or
consolidation with the original Tenant under this Lease or (z) which acquires
all or substantially all of the assets of the original Tenant under this Lease
for a legitimate business purpose.

      12.02 Rentals Based on Net Income. Without limiting the generality of the
foregoing provisions of this Article, Tenant expressly covenants and agrees not
to enter into any lease, sublease, license, concession or other agreement for
use, occupancy or utilization of the Premises which provides for rental or other
payment for such use, occupancy or utilization based in whole or in part on the
net income or profits derived by any person from the property leased, used,
occupied or utilized (other than an amount based on a fixed percentage or
percentages of receipts or sales), and that any such purported lease, sublease,
license, concession or other

                                                                              13
<PAGE>

agreement shall be absolutely void and ineffective as a conveyance of any right
or interest in the possession, use, occupancy or utilization of any part of the
Premises.

      12.03 Tenant to Remain Obligated. Consent by Landlord to any assignment,
subletting, use, occupancy or transfer shall not operate to relieve Tenant from
any covenant or obligation hereunder, or be deemed to be a consent to or relieve
Tenant from obtaining Landlord's consent to any subsequent assignment, transfer,
lien, charge, subletting, use or occupancy. Tenant shall pay all of Landlord's
costs, charges and expenses, including attorneys' fees, incurred in connection
with any assignment, transfer, lien, charge, subletting, use or occupancy made
or requested by Tenant.

      12.04 Tenants Notice; Landlord's Right to Terminate. Tenant shall advise
Landlord, by written notice, of its intention from, on and after a stated date
(which date shall not be less than sixty (60) days after the date of Tenant's
notice) to assign this Lease or to sublet any part or all of the Premises for
the balance of any part of the Term. If at any time Tenant sends notice to
Landlord of a prospective assignment or a sublease, the effect of which would
result in more than fifty percent (50%) of the rentable square footage of the
Premises to be subject to one or more subleases, Landlord shall have the right,
to be exercised by Landlord giving written notice to Tenant within thirty (30)
days after receipt by Landlord of Tenant's notice, to recapture all of the
Premises (in the case of a proposed assignment) or any part of the Premises
described in Tenant's notice (in the case of a proposed sublease) and such
recapture notice, if given, shall terminate this Lease (in the case of a
proposed assignment) or that portion of the Premises described in Tenant's
notice (in the case of a proposed sublease) as of the date stated in Tenant's
notice. Tenant's notice shall state the name and address of the proposed
subtenant or assignee, and a true and complete copy of the proposed sublease or
assignment and sufficient information to permit Landlord to determine the
financial responsibility and character of the proposed subtenant or assignee
shall be delivered to Landlord with said notice. If Tenant's notice covers all
of the space hereby demised, and if Landlord gives the aforesaid recapture
notice with respect thereto, the Term of this Lease shall expire on the date
stated in Tenant's notice as fully and completely as if that date had been
definitely fixed herein for the expiration of the Term. If, however, this Lease
is terminated pursuant to the foregoing with respect to less than the entire
Premises, Base Rent and Tenant's Proportionate Share as defined herein shall be
adjusted on the basis of the number of rentable square feet retained by Tenant,
and this Lease as so amended shall continue thereafter in full force and effect.

      12.05 Landlord's Consent. Subject to Landlord's rights to terminate
pursuant to Section 12.04, Landlord will not withhold its consent unreasonably
to Tenant's assignment of this Lease or Tenant's subletting the space covered by
its notice. Landlord shall not be deemed to have withheld its consent
unreasonably to a sublease of part or all of the Premises or an assignment of
this Lease if its consent is withheld because: (a) Tenant is then in default
hereunder; (b) any notice of termination of this Lease or termination of
Tenant's possession is given under Article 16; (c) the portion of the Premises
which Tenant proposes to sublease, including the means of ingress thereto and
egress therefrom and the proposed use thereof, and the remaining portion of the
Premises will violate any city, stale or federal law, ordinance or regulation,
including, without limitation, any applicable building code or zoning
ordinances; (d) the proposed use of the Premises by the subtenant or assignee
does not conform with the use permitted by Article 4; (e) in the reasonable
judgment of Landlord, the proposed subtenant or assignee is of a character or is
engaged in a business which would be deleterious to the reputation of the
Building, or the subtenant or assignee is not sufficiently financially
responsible to perform its obligations under the proposed sublease or
assignment; or (f) the proposed subtenant or assignee is a government or a
government agency; Building; provided, however, that the foregoing are merely
examples of reasons for which Landlord may withhold its consent and shall

                                                                              14
<PAGE>

not be deemed exclusive of any permitted reasons for reasonably withholding
consent, whether similar to or dissimilar from to the foregoing examples.

      12.06 Profits. If Tenant, having first obtained Landlord's consent to any
sublease or assignment, or if Tenant or a trustee in bankruptcy for Tenant
pursuant to the Bankruptcy Code, assigns this Lease or sublets the Premises, or
any part thereof, at a rental or for other consideration in excess of the Rent
or pro rata portion thereof due and payable by Tenant under this Lease, then
Tenant shall pay to Landlord as additional rent any such excess rent or other
monetary consideration immediately upon receipt under any such assignment or, in
the case of a sublease, (a) on the first day of each month during the term of
any sublease the excess of all rent and other consideration due from the
subtenant for such month over the Rent then payable to Landlord pursuant to the
provisions of this Lease for said month (or if only a portion of the Premises is
being sublet, the excess of all rent and other consideration due from the
subtenant for such month over the portion of the Rent then payable to Landlord
pursuant to the provisions of this Lease for said month which is allocable on a
square footage basis to the space sublet) and (b) immediately upon receipt
thereof, any other consideration realized by Tenant from such subletting; it
being agreed, however, that Landlord shall not be responsible for any deficiency
if Tenant assigns this Lease or sublets the Premises or any part thereof at a
rental less than that provided for herein.

      12.07 Assignee to Assume Obligations. If Tenant assigns this Lease as
permitted herein, the assignee shall expressly assume all of the obligations of
Tenant hereunder in a written instrument satisfactory to Landlord and furnished
to Landlord not later than fifteen (15) days prior to the effective date of the
assignment. If Tenant subleases the Premises as permitted herein, Tenant shall
obtain and furnish to Landlord, not later than fifteen (15) days prior to the
effective date of such sublease and in form satisfactory to Landlord, the
written agreement of such subtenant to the effect that the subtenant will attorn
to Landlord, at Landlord's option and written request, in the event this Lease
terminates before the expiration of the sublease.

      12.08 Change of Control. Notwithstanding anything to the contrary in this
Article, if, during the Term of this Lease, the ownership of the shares of stock
which constitute control of Tenant changes other than by reason of gift or
death, then Tenant shall notify Landlord of such change within five (5) days
thereof, whereupon Landlord, at its option, may terminate this Lease within
sixty (60) days after Landlord is notified of such change by giving Tenant
written notice of said termination at least sixty (60) days prior to the date of
termination stated in the notice; provided, however, Landlord shall have no
right to terminate this Lease if, upon a change of control, the net worth
(including intangible net worth) of the Tenant or any guarantor of the then
remainder of this Lease is at least equal to the greater of Tenant's net worth
(including intangible net worth) on (a) the Commencement Date or (b) the day
immediately preceding a change of control. If Tenant is a general or limited
partnership and if during the Term of this Lease, the ownership of the
partnership interests which constitute control of Tenant changes other than by
reason of gift or death, the provisions hereinabove set forth relating to a
Tenant which is a corporation which is not publicly traded shall apply and
references to ownership of stock shall be deemed to refer to ownership of
partnership interests in said partnership. The term "control" as used herein
means the power, directly or indirectly, to direct or to cause the direction of
the management or policies of Tenant.

                  WAIVER OF CERTAIN CLAIMS; INDEMNITY BY TENANT

      13.01 Waiver of Certain Claims; Indemnity by Tenant.

                                                                              15
<PAGE>

            (a) Except as otherwise required under law, but in all events,
subject to the mutual waiver of claims and subrogation set forth in this Lease,
Landlord and other Indemnified Parties (as hereinafter defined) shall not in any
event whatsoever be liable for any injury or damage to Tenant or to any other
Person happening in, on or about the Premises and its appurtenances, nor for any
injury or damage to the Premises or to any property belonging to Tenant or any
other Person which may be caused by any fire or breakage or by any other cause
whatsoever or by the use, misuse or abuse of the Building (including, but not
limited to, any of the common areas within the Building, and the other
improvements, equipment serving the Building, elevators, hatches, openings,
installations, stairways, hallways or other common facilities) or the streets or
sidewalk area within the Premises or which may arise from any other cause
whatsoever.

            (b) Landlord and other Indemnified Parties shall not be liable to
Tenant or to any other Person for any failure of water supply, gas, telephone or
electric current, nor for any injury or damage to any property of Tenant or of
any other Person or to the Premises caused by or resulting from gasoline, oil,
steam, gas or electricity or hurricane, tornado, flood, wind or similar storms
or disturbances, or water, rain, sleet, ice or snow which may leak or flow from
the street, sewer, gas mains or subsurface area or from any part of the
Premises, or leakage of gasoline or oil from pipes, storage tanks, appliances,
sewers or plumbing works therein, or from any other place or from any other
cause, nor for interference with light or other incorporeal hereditaments by
anybody, or caused by any public or quasi-public work.

      13.02 Tenant Responsible for Personal Property. All personal property
belonging to Tenant or any occupant of the Premises that is in the Building or
the Premises shall be there at the risk of Tenant or other person only and
Landlord shall not be liable for damage thereto or theft or misappropriation
thereof.

      13.03 Indemnification.

            (a) Tenant shall not do or permit any act or thing to be done upon
the Premises which may subject Landlord to any liability or responsibility for
injury, damage to persons or property, or to any liability by reason of any
violation of law or of any laws, and shall exercise such control over the
Premises so as to fully protect Landlord against any such liability. Tenant
shall indemnify and save Landlord and any agent, beneficiary, contractor,
director, employee, lessor, mortgagee, officer, parent, partner, shareholder and
trustee of Landlord (each an "Indemnified Party") harmless from and against any
and all liabilities, suits, obligations, fines, damages, penalties, claims,
costs, charges and expenses, including, without limitation, engineers',
architects' and attorneys' fees, court costs and disbursements, which may be
imposed upon or incurred by or asserted against any Indemnified Party by reason
of any of the following occurring during or after (but attributable to a period
of time falling within) the Term:

                  (i) any demolition or razing or construction of the Building
or any other work or thing done in, on or about the Premises or any part
thereof;

                  (ii) any use, nonuse, possession, occupation, alteration,
repair, condition, operation, maintenance or management of the Premises or any
part thereof or of any sidewalk, curb or vault adjacent thereto;

                  (iii) any act or failure to act on the part of Tenant or any
Subtenant or any of its or their respective officers, agents, employees or
licensees;

                                                                              16
<PAGE>

                  (iv) any accident, injury (including death at any time
resulting therefrom) or damage to any person or property occurring in, on or
about the Premises or any part thereof or in, on or about any sidewalk, curb or
vault adjacent thereto;

                  (v) any failure on the part of Tenant to pay the Base Rental
or to perform or comply with any of the covenants, agreements, terms or
conditions contained in this Lease on Tenant's part to be performed or complied
with;

                  (vi) any lien or claim which may be alleged to have arisen
against or on the Premises, or any lien or claim which may be alleged to have
arisen out of this Lease and created or permitted to be created by Tenant
against any assets of Landlord under any law, or any liability which may be
asserted against Landlord with respect thereto;

                  (vii) any failure on the part of Tenant to keep, observe and
perform any of the terms, covenants, agreements, provisions, conditions or
limitations contained in any subleases or other contracts and agreements
affecting the Premises on Tenant's part to be kept, observed or performed; and

                  (viii) any contest permitted pursuant to the provisions of
Article 3 hereof.

            (b) The obligations of Tenant under this Article 13 shall not be
affected in any way by the absence in any case of covering insurance or by the
failure or refusal of any insurance carrier to perform any obligation on its
part under insurance policies affecting the Premises or any part thereof.

            (c) If any claim, action or proceeding is made or brought against
any Indemnified Party against which it is indemnified pursuant to this Section
13.03, then, upon demand by Landlord, Tenant shall resist or defend such claim,
action or proceedings in Landlord's name, if necessary, by the attorneys for
Tenant's insurance carrier (if such claim, action or proceeding is covered by
insurance), otherwise by such attorneys as Landlord shall approve, which
approval shall not be unreasonably withheld or delayed. The foregoing
notwithstanding, Landlord may engage its own attorneys to defend it or to assist
in its defense, and Tenant shall pay the reasonable fees and disbursements of
such attorneys.

            (d) The provisions of this Section 13.03 shall survive the
Expiration Date with respect to any liability, suit, obligation, fine, damage,
penalty, claim, cost, charge or expense arising out of or in connection with any
matter which is the subject of indemnification under this Section 13.03.

      13.04 Landlord's Liability. Notwithstanding anything contained in the
foregoing, Landlord shall not be released from, nor shall Tenant indemnify
Landlord against, any liability arising out of facts, events or circumstances
unrelated to the Premises, the Building, this Lease, or any of the parties'
respective rights, obligations or activities with respect to this Lease.

                       USE OF CASUALTY INSURANCE PROCEEDS

      14.01 Tenant's Obligation to Restore. If all or any part of the
Improvements shall be destroyed or damaged in whole or in part by fire or other
casualty (whether or not insured) of any kind or nature, ordinary or
extraordinary, foreseen or unforeseen, Tenant shall give Landlord immediate
notice thereof (except with respect to partial damage the reasonably estimated
cost of repair of which shall be less than $100,000), and Tenant, whether or not
such damage or

                                                                              17
<PAGE>

destruction shall have been insured or insurable, and whether or not insurance
proceeds, if any, shall be sufficient for the purpose, and whether or not the
Leasehold Mortgagee shall permit such insurance proceeds to be used for such
repairs, alterations, restorations, replacements and rebuilding (collectively,
"Restoration"), with reasonable diligence (subject to Unavoidable Delays) shall
repair, alter, restore, replace and rebuild (collectively, "Restore") the same,
at least to the extent of the value and as nearly as practicable to the
character of the Improvements existing immediately prior to such occurrence, and
Landlord, in no event, shall be called upon to Restore the Improvements, as now
or hereafter existing, or any portion thereof or to pay any of the costs or
expenses thereof. If Tenant shall fail or neglect to Restore with reasonable
diligence (subject to Unavoidable Delays) the Improvements or the portion
thereof damaged or destroyed, or, having so commenced such Restoration, shall
fail to complete the same with reasonable diligence (subject to Unavoidable
Delays) in accordance with the terns of this Lease, Landlord may complete such
Restoration at Tenant's expense. Upon Landlord's electron to so complete the
Restoration, Tenant immediately shall pay to Landlord all insurance proceeds
which shall have been received by Tenant, minus those amounts, if any, which
Tenant shall have applied to the Restoration, and if such sums are insufficient
to complete the Restoration, Tenant, on demand, shall pay the deficiency to
Landlord. Each Restoration shall be done in accordance with the provisions of
this Lease.

      14.02 Payment for Restoration. Subject to the provisions of Section 14.03,
Depository shall pay over to Tenant from time to time, upon the following terms,
any monies which may be received by Depositary from insurance provided by Tenant
(other than rent insurance) (collectively, the "Restoration Funds"); provided,
however, that Depositary, before paying such monies over to Tenant, shall be
entitled to reimburse itself and Landlord therefrom to the extent, if any, of
the expenses paid or incurred by Depository or Landlord in the collection of
such monies. Depositary shall pay to Tenant the Restoration Funds for the
purpose of Restoration to be made by Tenant to Restore the Improvements to a
value which shall be not less than the value prior to such fire or other
casualty. Such Restoration shall be done in accordance with, and subject to, the
provisions of Article 11, including, without limitation, the maintenance of the
insurance coverage referred to in Article 11. Prior to the making of any
Restoration (except with respect to partial damage, the reasonably estimated
cost of Restoration of which shall be less than $100,000), Tenant shall furnish
Landlord with an estimate of the cost of such Restoration (the "Estimate"),
prepared by a licensed professional engineer or registered architect approved by
Landlord, which approval shall not be unreasonably withheld or delayed. The
Restoration Funds shall be paid to Tenant from time to time thereafter in
installments as the Restoration progresses upon application to be submitted from
time to time by Tenant to Depository and Landlord showing the cost of work,
labor, services, materials, fixtures and equipment incorporated in the
Restoration, or incorporated therein since the last previous application, and
paid for by Tenant or then due and owing. If any vendors', mechanics',
laborers', or materialmen's lien is filed against the Premises or any part
thereof, Tenant shall not be entitled to receive any further installment until
such lien is satisfied or otherwise discharged. The amount of any installment to
be paid to Tenant shall be such proportion of the total Restoration Funds as the
cost of work, labor, services, materials, fixtures and equipment theretofore
incorporated by Tenant into the Restoration bears to the Estimate, less (a) all
payments heretofore made to Tenant out of the Restoration Funds, and (b) ten
percent (10%) of the amount so determined. Upon completion of and payment for
the Restoration by Tenant, the balance of the Restoration Funds shall be paid
over to Tenant, subject to the rights of any Mortgagee named as an insured. If
the Estimate (i) is equal to or greater than $100,000, and (ii) exceeds the
insurance proceeds received by Depositary, then, prior to the commencement of
such Restoration or thereafter if at any time it is reasonably determined by
Landlord that the cost to complete the Restoration exceeds the unapplied portion
of such insurance proceeds, Tenant shall from time to time immediately deposit
with Depositary a bond, cash, irrevocable letter of credit or other security
reasonably satisfactory to Landlord in the amount

                                                                              18
<PAGE>

of such excess, to be held and applied by Depositary in accordance with the
provisions of this Section 14.02, as security for the completion of the work,
free of public improvement, vendors', mechanics', laborers' or materialmen's
statutory or other similar liens. If Landlord makes the Restoration at Tenant's
expense, as provided in Section 14.01, then, as provided above with respect to
Tenant, Depositary shall pay over the Restoration Funds to Landlord, from time
to time, upon Landlord's application accompanied by a certificate containing the
statements required under clauses (i), (ii) and (iii) of Section 14.03(a), to
the extent not previously paid to Tenant pursuant to this Section 14.02, and
Tenant shall pay to Depositary, on demand, any sums which Landlord certifies to
be an estimate of the amount necessary to complete the Restoration, less the
undisbursed Restoration Funds.

      14.03 Conditions to Payment of Proceeds. The following shall be conditions
precedent to each payment made to Tenant as provided in Section 14.02 above:

            (a) There shall be submitted to Depositary and Landlord the
certificate of the engineer or architect referred to in Section 14.02 hereof
stating (i) that the sum then requested to be withdrawn either has been paid by
Tenant or is justly due to contractors, subcontractors, materialmen, engineers,
architects or other Persons (whose names and addresses shall be stated) who have
rendered or furnished work, labor, services, materials, fixtures or equipment
for the work and giving a brief description of such work, labor, services,
materials, fixtures or equipment and the principal subdivisions or categories
thereof and the several amounts so paid or due to each of said Persons in
respect thereof, and stating in reasonable detail the progress of the
Restoration up to the date of said certificate; (ii) that no part of such
expenditures has been or is being made the basis, in any previous or then
pending request, for the withdrawal of insurance money or has been made out of
the proceeds of insurance received by Tenant; (iii) that the sum then requested
does not exceed ninety percent (90%) of the cost of the work, labor, services,
materials, fixtures and equipment described in the certificate; (iv) that the
balance of the Restoration Funds held by Depositary will be sufficient, upon
completion of the Restoration, to pay for the same in full, and stating in
reasonable detail an estimate of the cost of such completion; and (v)
appropriate sworn statements and lien waivers (which comply with the mechanics'
lien laws of the State of Michigan) from all Persons receiving payment under
such draw;

            (b) There shall be furnished to Depositary a date-down endorsement,
or a similar certificate of a title insurance company reasonably satisfactory to
Depositary, showing that there are no vendors', mechanics', laborers' or
materialmen's or other liens affecting the Premises or any part thereof in
connection with work done, authorized or incurred at or relating to the Premises
which had not been discharged of record, except such as will be discharged upon
payment of the amount then requested to be withdrawn; and

            (c) At the time of making such payment, there is no Default on the
part of Tenant under this Lease, which has not been cured.

      14.04 No Abatement of Rent. This Lease shall not terminate, be forfeited
or be affected in any manner, nor shall there be any reduction or abatement of
the Rent payable hereunder, by reason of damage to or total, substantial or
partial destruction of the Building or any part thereof or by reason of the
untenantability of the same or any part thereof, for or due to any reason or
cause whatsoever, and Tenant, notwithstanding any law or statute present or
future, waives any and all rights to quit or surrender the Premises or any part
thereof; and Tenant's obligations hereunder, including, without limitation, the
payment of Rent hereunder, shall continue as though the Improvements had not
been damaged or destroyed and without abatement, suspension, diminution or
reduction of any kind.

                                                                              19

      14.05 Mortgagee's Application Of Insurance Proceeds. Notwithstanding
anything contained in the Lease to the contrary, in the event (i) all or any
part of the Improvements shall be destroyed or damaged in whole or in part by
fire or other casualty, and monies are received as a result of such damage or
destruction from Insurance provided by Tenant (the "Proceeds") and (ii) Landlord
is required by its Mortgagee to use such Proceeds to pay down any debt from
Landlord to such Mortgagee, then Landlord shall make available to or for the
benefit of Tenant for Restoration, in accordance with Article 14, an amount
equal to the Proceeds so that the such amount constitutes Restoration Funds;
provided, however Tenant shall be entitled to such amount so long as the
following conditions are satisfied:

      1.    No Default has occurred and remains uncured;

      2.    The Lease remains in full force and effect, and

      3.    Tenant shall not have exercised any right of termination contained
            herein; and Tenant agrees in writing to diligently pursue the
            Restoration to completion in accordance with Article 14.

                                   ARTICLE 15
                                 EMINENT DOMAIN

      15.01 Complete Condemnation. If the entire Premises or Building or a
substantial part thereof is taken or condemned by any competent authority for
any public or quasi-public use or purpose, the Term of this Lease shall end upon
and not before the earlier of (i) the date when the possession of the part so
taken is required for such use or purpose or (ii) the effective date of the
taking. Landlord and Tenant shall each be entitled to receive such separate
awards as may be allocated to their respective interests in any such
proceedings, including in the case of Tenant any award made to it for
depreciation to or loss of and cost of removal of furniture, fixtures, equipment
and inventory; provided that Tenant shall not be entitled to any portion of any
award, regardless of the value of Tenant's leasehold interest, the effect of
which would be to reduce the aggregate award properly claimed by and allocable
to Landlord and instead, Landlord shall be entitled to such award to the extent
of such reduction. Termination of this Lease pursuant to its provisions shall
not affect the rights of the respective parties of such awards. If any
condemnation proceeding is instituted in which it is sought to take or damage
any part of the Improvements, the taking of which, in Landlord's opinion, would
prevent the economical operation of the Building, or if the grade of any street
or alley adjacent to the Improvements is changed by any competent authority, and
such taking, damage or change of grade makes it necessary or desirable to
remodel the Improvements to conform to the taking, damage or changed grade,
unless Tenant agrees in writing to undertake satisfaction of conditions,
Landlord shall have the right to terminate this Lease upon not less than ninety
(90) days' notice prior to the date of termination designated in the notice. In
either of these events, Rent at the then current rate shall be apportioned as of
the date of the termination. No money or other consideration shall be payable by
Landlord to Tenant for the right of termination, and Tenant shall have no right
to share in the condemnation award, whether for a total or partial taking, for
loss of Tenant's leasehold or improvements or other loss or expenses or in any
judgment for damages caused by the change of grade.

      15.02 Partial Condemnation. In the event only a part of the Premises is
condemned and the remaining part thereof, in the reasonable opinion of Landlord
and Tenant, remains reasonably suitable for the continuation of the business
then being conducted thereon, this Lease shall, as to the part so condemned,
terminate on the date of Condemnation, and the Base Rent shall thereupon be
reduced in the same proportion that the number of square feet of the Premises so
taken bears to the original number of square feet of the Premises. Landlord and
Tenant shall

                                                                              20
<PAGE>

each be entitled to receive such separate awards as may be allocated to their
respective interests in any such proceedings, including in the case of Tenant
any award made to it for depreciation to or loss of and cost of removal of
furniture, fixtures, equipment and inventory; provided that Tenant shall not be
entitled to any portion of any award, regardless of the value of Tenant's
leasehold interest, the effect of which would be to reduce the aggregate award
property claimed by and allocable to Landlord and instead, Landlord shall be
entitled to such award to the extent of such reduction.

      15.03 Condemnation Near Termination. In the event only a part of the
Premises is condemned within eighteen (18) months of the end of the Term or a
renewal Term hereof, as the case may be, this Lease shall, as to the part so
condemned, terminate on the date of Condemnation, and the Base Rent shall
thereupon be reduced in the same proportion that the number of square feet of
the Premises so taken bears to the original number of square feet of the
Premises, and the balance of this Lease shall, at the election of Tenant,
terminate on a date during the remaining Term which is provided to Landlord in
writing by Tenant.

legal process of, the leasehold interest of Tenant, or the filing or creation of
a lien with respect to such leasehold interest, which lien shall not be released

in good faith, commences a contest of such filing within such ten (10) day
period and diligently pursues such contest until released and provides Landlord
with a bond or title indemnity from title company approved by Landlord;

                                                                              21
<PAGE>

continue to be vacated or abandoned for more than one hundred eighty (180) days;

            (i) Tenant becomes insolvent or bankrupt or admits in writing its

appointment; or

            (k) Any bankruptcy, reorganization, arrangement, insolvency or
liquidation proceedings, or other proceedings for relief under any bankruptcy
law, or similar law for the relief of debtors, are instituted (i) by Tenant or
(ii) against Tenant and are allowed against it or are consented to by it or are
not dismissed within sixty (60) days after such institution.

      16.02 Rights and Remedies of Landlord. If a Default occurs, Landlord shall
have the rights and remedies hereinafter set forth, which shall be distinct,
separate and cumulative and which shall not operate to exclude or deprive
Landlord of any other right or remedy allowed it by law:

            (a) Landlord may terminate this Lease by giving to Tenant notice of
Landlord's election to do so, in which event the Term of this Lease shall end,
and all rights, title and interest of Tenant hereunder shall expire, on the date
stated in such notice;

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

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

      16.03 Right to Re-Enter. If Landlord exercises either of the remedies
provided for in Sections 16.02(a) or (b), Tenant shall surrender possession and
vacate the Premises and shall deliver immediately possession thereof to
Landlord, and Landlord may re-enter and take complete and peaceful possession of
the Premises, with or without process of law, full and complete license to do so
being hereby granted to Landlord, and Landlord may remove all occupants and
property therefrom, using such force as may be necessary, without being deemed
guilty in any manner of trespass, eviction or forcible entry and detainer and
without relinquishing Landlord's right to rent or any other right given to
Landlord hereunder or by operation of law.

      16.04 Current Damages. If Landlord terminates the right of Tenant to
possession of the Premises without terminating this Lease, Landlord shall have
the right to immediate recovery of all amounts then due hereunder. Such
termination of possession shall not release Tenant, in whole or in part, from
Tenant's obligation to pay the Rent hereunder for the full Term, and Landlord
shall have the right, from time to time, to recover from Tenant, and Tenant
shall remain liable for, all Base Rent, Rent Adjustments and any other sums
accruing as they become due under this Lease during the period from the date of
such notice of termination of possession to the stated end of the Term. In any
such case, Landlord may relet the Premises or any part thereof for the account
of

                                                                              22
<PAGE>

Tenant for such rent, for such time (which may be for a term extending beyond
the Term of this Lease) and upon such terms as Landlord shall determine and
collect the rents from such reletting. Landlord shall not be required to accept
any tenant offered by Tenant or to observe any instructions given by Tenant
relative to such reletting. Also, in any such case, Landlord may make repairs,
alterations and additions in or to the Premises and redecorate the same to the
extent reasonably deemed by Landlord necessary or desirable and in connection
therewith change the locks to the Premises, and Tenant shall pay upon demand the
cost of all the foregoing together with Landlord's expenses of reletting. The
rents from any such reletting shall be applied first to the payment of the
expenses of reentry, redecoration, repair and alterations and the expenses of
reletting and second to the payment of Rent herein provided to be paid by
Tenant. Any excess or residue shall operate only as an offsetting credit against
the amount of Rent due and owing as the same thereafter becomes due and payable
hereunder, and the use of such offsetting credit to reduce the amount of Rent
due Landlord, if any, shall not be deemed to give Tenant any right, title or
interest in or to such excess or residue and any such excess or residue shall
belong to Landlord solely, and in no event shall Tenant be entitled to a credit
on its indebtedness to Landlord in excess of the aggregate sum, including Base
Rent and Rent Adjustments, which would have been paid by Tenant for the period
for which the credit to Tenant is being determined, had no Default occurred. No
such reentry or repossession, repairs, alterations and additions, or reletting
shall be construed as an eviction or ouster of Tenant or as an election on
Landlord's part to terminate this Lease, unless a written notice of such
intention is given to Tenant, or shall operate to release Tenant in whole or in
part from any of Tenant's obligations hereunder, and Landlord, at any time and
from time to time, may sue and recover judgment for any deficiencies from time
to time remaining after the application from time to time of the proceeds of any
such reletting. Notwithstanding the foregoing, Landlord shall use reasonable
efforts to mitigate the damages suffered by Tenant hereunder.

      16.05 Final Damages. If this Lease is terminated by Landlord as provided
in Section 16.02(a), Landlord shall be entitled to recover from Tenant all Rent
accrued and unpaid for the period up to and including such termination date, as
well as all other additional sums payable by Tenant, or for which Tenant is
liable or in respect of which Tenant has agreed to indemnify Landlord under any
of the provisions of this Lease, which may be then owing and unpaid, and all
costs and expenses, including court costs and attorneys' fees incurred by
Landlord in the enforcement of its rights and remedies hereunder, and, in
addition, Landlord shall be entitled to recover as damages for loss of the
bargain and not as a penalty (a) the unamortized portion of any alterations
installed by Landlord pursuant to this Lease or any work letter, (b) the
aggregate sum which at the time of such termination represents the excess, if
any, of the present value of the aggregate rents which would have been payable
after the termination date had this Lease not been terminated, including,
without limitation, Base Rent at the annual rate or respective annual rates for
the remainder of the Term provided for in Article 2 of this Lease or elsewhere
herein and the amount projected by Landlord to represent Rent Adjustments for
the remainder of the Term pursuant to Article 3 of this Lease, over the then
present value of the then aggregate fair rental value of the Premises for the
balance of the Term, such present worth to be computed in each case on the basis
of a five percent (5%) per annum discount from the respective dates upon which
such rentals would have been payable hereunder had this Lease not been
terminated, and (c) any damages in addition thereto, including reasonable
attorneys' fees and court costs, which Landlord has sustained as a result of the
breach of any of the covenants of this Lease other than for the payment of Rent.

      16.06 Removal of Personal Property. All property of Tenant removed from
the Premises by Landlord pursuant to any provisions of this Lease or of law may
be handled, removed or stored by Landlord at the cost and expense of Tenant, and
Landlord in no event shall be responsible for the value, preservation or
safekeeping thereof. Tenant shall pay Landlord for all expenses

                                                                              23
<PAGE>

incurred by Landlord in such removal and storage charges against such property
as long as the same is in Landlord's possession or under Landlord's control. All
such property not removed from the Premises or retaken from storage by Tenant
within thirty (30) days after the end of the Term, however terminated, at
Landlord's option, shall be conclusively deemed to have been conveyed by Tenant
to Landlord as by bill of sale without further payment or credit by Landlord to
Tenant.

      16.07 Attorneys' Fees. Tenant shall pay all of Landlord's costs, charges
and expenses, including court costs and attorneys' fees, incurred in enforcing
Tenant's obligations under this Lease, incurred by Landlord in any action
brought by Tenant in which Landlord is the prevailing party, or incurred by
Landlord in any litigation, negotiation or transaction in which Tenant causes
Landlord, without Landlord's fault, to become involved or concerned.

      16.08 Assumption or Rejection in Bankruptcy. If Tenant is adjudged
bankrupt, or a trustee in bankruptcy is appointed for Tenant, Landlord and
Tenant, to the extent permitted by law, agree to request that the trustee in
bankruptcy determine within sixty (60) days thereafter whether to assume or to
reject this Lease.

                                  SUBORDINATION

      17.01 Subordination. Landlord has executed and delivered and may execute
and deliver hereafter from time to time a mortgage or trust deed in the nature
of a mortgage, both being hereinafter referred to as a "Mortgage," against the
Land and Improvements or any interest therein. If requested by the mortgagee or
trustee under any Mortgage (both being hereinafter referred to as a
"Mortgagee"), Tenant will either (a) subordinate its interest in this Lease to
said Mortgage, and to any and all advances made thereunder and to the interest
thereon, and to all renewals, replacements, supplements, amendments,
modifications and extensions thereof, or (b) make certain of Tenant's rights and
interest in this Lease superior thereto; and Tenant will execute and deliver
such agreement or agreements promptly, as may be reasonably required by such
mortgagee or trustee under any Mortgage; provided that, as a condition to
subordinating its rights and interests under this Lease to any mortgage or trust
deed, Tenant shall be entitled to require Mortgagee to enter into a customary
non-disturbance and attornment agreement with Tenant, which agreement shall be
in form as agreed to by said Mortgagee. If Tenant fails to execute such
agreement or agreements as aforesaid for more then ten (10) days following a
request thereof, Landlord shall be entitled to execute same as Tenant's
attorney-in-fact without any further action on the part of the Tenant.

      17.02 Liability of Mortgagee; Attornment. It is further agreed that (a) if
any Mortgage shall be foreclosed, (i) the Mortgagee (or its grantees) or
purchaser at any foreclosure sale (or grantee in a deed in lieu of foreclosure),
as the case may be, shall not be (x) liable for any act or omission of any prior
landlord (including Landlord), (y) subject to any offsets or counterclaims which
Tenant may have against a prior landlord (including Landlord), or (z) bound by
any prepayment of Base Rent which Tenant may have made In excess of the amounts
then due for the next succeeding month, (ii) the liability of the Mortgagee
hereunder or purchaser at such foreclosure sale or the liability of a subsequent
owner designated as Landlord under this Lease shall exist only so long as such
Mortgagee, purchaser or owner is the owner of the Building or Land and such
liability shall not continue or survive after further transfer of ownership; and
(iii) upon request of the Mortgagee, if the Mortgage is foreclosed, Tenant will
attorn, as Tenant under this Lease, to the purchaser at any foreclosure sale
under any Mortgage, and Tenant will execute such instruments as may be necessary
or appropriate to evidence such attornment; and (b) this Lease may not be
modified or amended so as to reduce Rent or shorten the Term provided hereunder,
or so as to affect adversely in any other respect to any material extent the
rights of

                                                                              24
<PAGE>

Landlord, and this Lease shall not be cancelled or surrendered, without the
prior written consent, in each instance, of the Mortgagee.

      17.03 Modification Required by Mortgagee. Should any prospective Mortgagee
require a modification or modifications of this Lease, which modification or
modifications will not cause an increased cost or expense to Tenant or in any
other way materially change the rights and obligations of Tenant hereunder
(e.g., changes to notice provisions, correction of administrative omissions,
etc.). Tenant agrees that this Lease may be so modified and agrees to execute
whatever documents are required therefor and deliver the same to Landlord within
ten (10) days following the request therefor.

      17.04 Short Form Lease. Should any prospective Mortgagee require execution
of a short form of lease for recording (containing the names of the parties, a
description of the Premises, and the term of this Lease) or a certification from
Tenant concerning this Lease in such form as may be required by a prospective
mortgagee, Tenant agrees to promptly execute such short form of lease or
certificate and deliver the same to Landlord within ten (10) days following the
request therefor.

                                   ARTICLE 18
                              MORTGAGEE PROTECTION

      Tenant agrees to give the Mortgagee, by registered or certified mail, a
copy of any notice or claim of default served upon Landlord by Tenant, provided
that prior to such notice, Tenant has been notified in writing, by way of
service on Tenant of a copy of an assignment of Landlord's interests in leases,
or otherwise, of the address of such Mortgagee. Tenant further agrees that if
Landlord has failed to cure such default within twenty (20) days after such
notice to Landlord (or if such default cannot be cured or corrected within that
time, then such additional time as may be necessary if Landlord has commenced
within such twenty (20) days and is pursuing diligently the remedies or steps
necessary to cure or correct such default), then the Mortgagee shall have an
additional thirty (30) days within which to cure or correct such default (or if
such default cannot be cured or corrected within that time, then such additional
time as may be necessary if such Mortgagee has commenced within such thirty (30)
days and is pursuing diligently the remedies or steps necessary to cure or
correct such default, including the time necessary to obtain possession if
possession is necessary to cure or correct such default).

                              ESTOPPEL CERTIFICATE

      Tenant agrees that from time to time upon not less than ten (10) days'
prior request by Landlord, or the holder of any Mortgage or any ground lessor,
Tenant (or any permitted assignee, subtenant, licensee, concessionaire or other
occupant of the Premises claiming by, through or under Tenant) will deliver to
Landlord or to the Mortgagee or ground lessor, a statement in writing signed by
Tenant certifying (a) that this Lease is unmodified and in full force and effect
(or if there have been modifications, that this Lease as modified is in full
force and effect and identifying the modifications); (b) the date upon which

completed in accordance with the terms hereof and Tenant is in occupancy and
paying Rent on a current basis with no rental offsets or claims; (e) that there
has been no prepayment of Rent other than that provided for in this Lease or, if
not true, identifying such payments; (f) that there are no actions, whether
voluntary or otherwise, pending against Tenant under the bankruptcy laws of the
United States or any State thereof; and (g) such other matters as may be
required by Landlord in

                                                                              25

connection with the sale or other transfer of the Premises or portion thereof,
or by the Mortgagee or ground lessor.

                                 RENEWAL OPTIONS

      Landlord agrees that, so long as no Default has occurred and Tenant gives
Landlord the prior written notice hereinafter described, Tenant shall have, and
it is hereby granted, two (2) successive options to extend the Term for a period
of ten (10) years on each option (individually, an "Option Period", and jointly,
the "Option Periods"), such Option Period to begin respectively upon the
expiration of the initial fifteen (15) year Term of this Lease or the prior
Option Period, as the case may be. All of the terms, covenants and provisions of
this Lease shall apply to each Option Period, except that Base Rent for each of
the Option Periods shall be as set forth in Exhibit B hereto, payable in equal
monthly installments as Monthly Base. In order to exercise such options to
extend, Tenant shall give Landlord notice of such exercise no later than three
hundred sixty-five (365) days prior to the end of the initial fifteen (15) year
Term of this Lease or the prior Option Period, as the case may be. Upon the
failure of Tenant to exercise one or either of the options herein, and, in any
event, upon expiration of the second of such Option Periods, Tenant shall have
no further or additional right to renew or extend the Lease.

                                   ARTICLE 21
                                    NONWAIVER

      No waiver of any condition expressed in this Lease shall be implied by any
neglect of Landlord to enforce any remedy on account of the violation of such
condition whether or not such violation is continued or repeated subsequently,
and no express waiver shall affect any condition other than the one specified in
such waiver and that one only for the time and in the manner specifically
stated. Without limiting Landlord's rights under Article 8, it is agreed that no
receipt of monies by Landlord from Tenant after the termination in any way of
the Term or of Tenant's right of possession hereunder or after the giving of any
notice shall reinstate, continue or extend the Term or affect any notice given
to Tenant prior to the receipt of such monies. It is also agreed that after the
service of notice or the commencement of a suit or after final judgment for
possession of the Premises, Landlord may receive and collect any monies due, and
the payment of said monies shall not waive or affect said notice, suit or
judgment.

                       TENANT - CORPORATION OR PARTNERSHIP

      In case Tenant is a corporation, Tenant (a) represents and warrants that
this Lease has been duly authorized, executed and delivered by and on behalf of
Tenant and constitutes the valid and binding agreement of Tenant in accordance
with the terms hereof and (b) if Landlord so requests, it shall deliver to
Landlord or its agent, concurrently with the delivery of this Lease executed by
Tenant, certified resolutions of the board of directors (and shareholders, if
required) authorizing Tenant's execution and delivery of this Lease and the
performance of Tenant's obligations hereunder. In case, at any time during the
Term or renewal thereof, Tenant becomes a partnership, Tenant represents and
warrants that all of the persons who are general or managing partners in said
partnership have executed this Lease on behalf of Tenant, or that this Lease has
been executed and delivered pursuant to and in conformance with a valid and
effective authorization therefor by all of the general or managing partners of

                                SECURITY DEPOSIT

      26.01 Security Deposit. Tenant has deposited with Landlord (or its
beneficiary, if Landlord is a land trustee) the sum of Thirty One Thousand Six
Hundred Sixty-Six and 67/100 Dollars ($31,666.67) as security for the full and
faithful performance of every provision of this Lease to be performed by Tenant.
If Tenant Defaults with respect to any provision of this Lease, including but
not limited to, the provisions relating to the payment of Rent, Landlord may
use, apply or retain all or any part of said security deposit for the payment of
any Rent and any other sum in default, or for the payment of any other amount
which Landlord may spend or becomes obligated to spend as a result of Tenant's
Default or to compensate Landlord for any other loss or damage which Landlord
may suffer as a result of Tenant's Default. If any portion of said security
deposit is to be used or applied, Tenant, within five (5) days after written
demand therefor, shall deposit cash with Landlord (or its beneficiary) in an
amount sufficient to restore the security deposit to its original amount and
Tenant's failure to do so shall be a material breach of this Lease. Landlord (or
its beneficiary) shall not be required to keep said security deposit separate
from its general funds and Tenant shall not be entitled to interest on any
security deposit. If Tenant fully and faithfully performs every provision of
this Lease to be performed by it, said security deposit or any balance thereof

Term and Tenant's vacation of the Premises.

                                                                              30
<PAGE>

any security deposit required by Landlord hereunder, unless said sums have
actually been received by said mortgagee as security for Tenant's performance of
this Lease. Landlord may deliver the funds deposited hereunder by Tenant to the
purchaser of Landlord's interest in the Building, in the event that such
interest is sold, and thereupon Landlord (and its beneficiary, if any) shall be
discharged from any further liability with respect to said security deposit.

                        TITLE AND COVENANT AGAINST LIENS

      Landlord's title is and always shall be paramount to the title of Tenant
and nothing contained in this Lease shall empower Tenant to do any act which
can, shall or may encumber the title of Landlord. Tenant covenants and agrees
not to suffer or permit any lien of mechanics or materialmen to be placed upon
or against the Premises, the Building, the Land or against Tenant's leasehold
interest in the Premises and, in case of any such lien attaching, to pay and
remove same immediately. Tenant has no authority or power to cause or permit any
lien or encumbrance of any kind whatsoever, whether created by act of Tenant,
operation of law or otherwise, to attach to or to be placed upon the Premises,
the Building or the Land, and any and all liens and encumbrances created by
Tenant shall attach only to Tenant's interest in the Premises. If any such liens
so attach and Tenant fails to pay and remove same within ten (10) days,
Landlord, at its election, may pay and satisfy the same and in such event the
sums so paid by Landlord, with interest from the date of payment at the rate set
forth in Section 28.08 for amounts owed Landlord by Tenant. Such sums shall be
deemed to be additional rent due and payable by Tenant at once without notice or
demand.

                                  MISCELLANEOUS

      28.01 Successors and Assigns. Each provision of this Lease shall extend to

mortgage, encumbrance, lien, charge or subletting contrary to the provisions of

this Lease or of any of its conditions or provisions shall be binding upon
Landlord unless in writing and signed by Landlord.

      28.03 No Option; Irrevocable Offer. Submission of this instrument for
examination shall not constitute a reservation of or option for the Premises or
in any manner bind Landlord and no lease or obligation on Landlord shall arise
until this instrument is signed and delivered by Landlord and Tenant; provided,
however, the execution and delivery by Tenant of this Lease to Landlord or the
agent of Landlord's beneficiary, if any, shall constitute an irrevocable offer
by Tenant to lease the Premises on the terms and conditions contained herein,
which offer may not be revoked for thirty (30) days after such delivery.

      28.04 Definition of Tenant. The word "Tenant" whenever used herein shall

Tenant, the liability of each shall be joint and several.

                                                                              31
<PAGE>

      28.05 Definition of Landlord. The term "Landlord" as used in this Lease
means only the owner or owners at the time being of the Building so that in the
event of any assignment, conveyance or sale, once or successively, of said
Building, or any assignment of this Lease by Landlord, said Landlord making such
sale, conveyance or assignment shall be and hereby is entirely freed and
relieved of all covenants and obligations of Landlord hereunder accruing after
such sale, conveyance or assignment, and Tenant agrees to look solely to such
purchaser, grantee or assignee with respect thereto. This Lease shall not be
affected by any such assignment, conveyance or sale, and Tenant agrees to attom

governmental laws and regulations, riots, insurrections, war, fuel shortages,
accidents, casualties, acts of God, acts caused directly or indirectly by Tenant
(or Tenant's agents, employees, contractors, licensees or invitees) or any other
cause beyond the reasonable control of Landlord, then Landlord shall not be
deemed in default under this Lease as a result of such failure and any time for
performance by Landlord provided for herein shall be extended by the period of
delay resulting from such cause.

                         AMERICANS WITH DISABILITIES ACT

      The parties acknowledge that the Americans With Disabilities Act of 1990
(42 U.S.C. Section 12101 et seq.) and regulations and guidelines promulgated
thereunder, as all of the same may be amended and supplemented from time to time
(collectively referred to herein as the "ADA") establish requirements under
Title III of the ADA ("Title III") pertaining to business operations,
accessibility and barrier removal, and that such requirements may be unclear and
may or may not apply to the Premises and the Building depending on, among other
things: (1) whether Tenant's business operations are deemed a "place of public
accommodation" or a "commercial facility," (2) whether compliance with such
requirements is "readily achievable" or "technically infeasible," and (3)
whether a given alteration affects a "primary function area" or triggers
so-called "path of travel" requirements. The parties acknowledge and agree that
Tenant has been provided an opportunity to inspect the Premises and the Building
sufficient to determine whether or not the Premises and the Building in their
condition current as of the date hereof deviate in any manner from the ADA
Accessibility Guidelines ("ADAAG") or any other requirements under the ADA
pertaining to the accessibility of the Premises or the Building. Tenant further
acknowledges and agrees that except as may otherwise be specifically provided
herein, Tenant accepts the Premises and the Building in "as-is" condition and
agrees that Landlord makes no representation or warranty as to whether the
Premises or the Building conform to the requirements of the ADAAG or any other
requirements under the ADA pertaining to the accessibility of the Premises or
the Building. Tenant has prepared or reviewed the plans and specifications for
the construction of the Building and has independently determined that such
plans and specifications are in conformance with the ADAAG and any other
requirements of the ADA. Tenant further acknowledges and agrees that to the
extent that Landlord prepared, reviewed or approved any of those plans and
specifications, such action shall in no event be deemed any representation or
warranty that the same comply with any requirements of the ADA. Notwithstanding
anything to the contrary in this Lease, the parties hereby agree to allocate
responsibility for Title III compliance as follows: (a) Tenant shall be
responsible for all Title III compliance and costs in connection with the
Premises, including structural work, if any, and including any leasehold
improvements or other work to be performed in the Premises under or in
connection with this Lease, and (b) Landlord shall perform, and Tenant shall be
responsible for the cost of, any so-called Title III "path of travel"
requirements triggered by any construction activities or alterations in the
Premises. Except as set forth above with respect to Landlord's Title III
obligations, Tenant shall be solely responsible for all other requirements under
the ADA relating to the Tenant or any affiliates or persons or entities related
to the Tenant (Collectively, "Affiliates"), operations of the Tenant or
Affiliates, or the Premises, including, without limitation, requirements under
Title I of the ADA pertaining to Tenant's employees.

                             EXCULPATORY PROVISIONS

      It is understood and agreed expressly by and between the parties hereto,
anything herein to the contrary notwithstanding, that each and all of the
representations, warranties, covenants, undertakings and agreements made herein
on the part of Landlord, while in form purporting to be the representations,
warranties, covenants, undertakings and agreements of Landlord, are nevertheless
each and every one of them made and intended, not as personal representations,
warranties, covenants, undertakings and agreements by Landlord or for the
purpose or with the intention of binding Landlord personally, but are made and
intended for the purpose only of

                                                                              33

subjecting Landlord's interest in the Building, the Land and the Premises to the

indebtedness accruing hereunder or to perform any covenant, either express or
implied, contained herein, and that, other than in connection with any unapplied
portion of the Security Deposit or escrows deposited in accordance with this

by, nor at any time shall be asserted or enforceable against, said Landlord,
individually.

      Tenant represents that it has provided Landlord with true and complete
financial statements (the "Financial Statements") setting forth the financial
condition of Tenant as of the date specified in such statements. Upon Landlord's
written request, Tenant shall promptly furnish Landlord with a written
certification from an executive officer, manager, or partner of Tenant
describing in reasonable detail any material adverse change in the financial
condition of Tenant from that set forth in the respective Financial Statements
or stating that there has been no such change. Upon Landlord's prior written
request, Tenant shall also promptly furnish to Landlord such other recent
financial statements and other relevant financial information relative to and
evidencing Tenant's financial condition, which financial statements and
financial information shall be certified as true, correct and complete by an
executive officer, manager or partner of Tenant.

                                   ARTICLE 32
                             RIGHT OF FIRST REFUSAL

      32.01 Right of First Refusal. Landlord and Tenant agree that in the event
Landlord or its heirs, executors, administrators, successors or assigns desires
to sell its entire legal or beneficial interest in the Premises and this Lease,
and Landlord or its heirs, executors, administrators, successors or assigns
shall have received a bona fide offer ("Third Party Offer"), which the recipient
desires to accept, from a third person to purchase the same, Landlord, shall, by
written notice (accompanied by a true, correct and complete copy of the Third
Party Offer) given to Tenant no later than three (3) days after receipt by
Landlord of such Third Party Offer, first offer the Premises, together with
Landlord's interest in this Lease, for sale to Tenant or its nominee. Except as
hereinafter set forth, such offer shall be at the price and upon the other terms
and conditions embodied in the Third Party Offer and as set forth in this
Section; provided, however, that if the Third Party Offer includes purchase
money financing from Landlord or other deferred payments of the purchase price,
then Tenant may only exercise its rights set forth in this Section 32.01 in the
event Tenant's creditworthiness is substantially similar to the party making the
Third Party Offer or otherwise reasonably satisfactory to Landlord.

      32.02 Election. Tenant shall have five (5) days after receipt by Tenant of
said written notice from Landlord in which to deliver to Landlord, or such other
offeree, a notice of its election to purchase the offered interest upon the
price, terms and conditions set forth in said notice to Tenant, and upon such
election to purchase, Landlord and Tenant shall enter into a contract for the
purchase of the Premises upon the terms and conditions specified in Landlord's
notice and such other terms and conditions as agreed to by the parties. If
Tenant elects to purchase the Premises as aforesaid, Landlord, or such other
offeree, shall sell its entire interest in the Premises, together with its
interest in this Lease, as offered to Tenant, and Tenant shall purchase the
same, and Tenant's notice of election shall be accompanied by a payment in the
amount, if any, specified as earnest money in the Third Party Offer as
communicated to Tenant. The closing of such purchase by Tenant shall occur at
the time and place set forth in the Third Party Offer, or

                                                                              34
<PAGE>

as mutually agreed to in writing by Landlord and Tenant, and each party shall
deliver such documents and take such action in connection with the closing as is
customary in similar commercial real estate transactions, except as otherwise
required herein.

      32.03 Termination of Right of First Refusal. If Tenant shall fail to give
notice of election to purchase the offered interest accompanied by payment
pursuant to this Article 32 or, after giving notice of election to purchase the
offered interest, shall fail to perform its obligations pursuant thereto,
Landlord, or such other offeree, may sell and convey the offered interest to the
third-person offeror upon the terms and conditions contained in the Third Party
Offer; provided, however, Tenant shall thereby forfeit its remaining rights to
exercise the rights of first refusal granted to it under this Article 32 as to a
subsequent sale of the Premises and the Lease by Landlord or such other offeree.

      32.04 No Assignment. The rights granted hereunder shall be personal to
Tenant and not assignable and apply only to a sale of the entire interest of
Landlord, or such other offeree, or its or their successors or assigns, and
shall not apply to any conveyance by Landlord or any transfer of the interest of
Landlord in the Premises to (a) a trust established for the benefit of Landlord;
(b) the legal representative of Landlord in the event of death or incompetency
of Landlord; (c) a trust, partnership or other entity controlled by Landlord; or
(d) a beneficiary of the estate of Landlord or a legatee or devisee of Landlord.

      32.05 Closing Procedure. If Tenant's option hereunder is exercised, the
following closing procedure shall apply:

            (a) The closing date for the sale of the Premises or other offered
interest, as applicable, to Tenant shall be such date as set forth in the Third
Party Offer. Payment of the purchase price and delivery of the deed (the
"Closing") shall be made at the office of Chicago Title Insurance Company (the
"Title Company") in Chicago, Illinois, or at such other place as the parties may
agree. At the request of either party, the Closing shall be effected through a
deed and money escrow, the cost of which escrow shall become equally by Landlord
and Tenant. The purchase price shall be payable to Landlord on the Closing date
in cash or by certified or cashier's check.

            (b) The conveyance of the Premises shall be made by recordable
warranty deed to Tenant (or its designee) sufficient to transfer good and
marketable fee simple title to the Premises to Tenant subject only to (i) the
lien of current general real estate taxes and special assessments not then due
and payable; (ii) any acts or doings caused or suffered by Tenant; (iii) such
title exceptions as set forth in the Third Party Offer; and (iv) such other
title exceptions as Tenant may then agree in writing to accept ("Permitted Title
Exceptions").

            (c) Landlord shall deliver or cause to be delivered to Tenant, not
later than twenty (20) days prior to the Closing, as evidence of Landlord's
title to the Premises, a commitment for an ALTA Form B owner's title insurance
policy (with extended coverage over all general exceptions) in the aggregate
amount of the purchase price as provided hereunder and a survey showing no
encroachments by or from the Land onto any adjacent property, no encroachments
buy or from the Land onto any adjacent property, no encroachments onto the Land
by any adjacent property and no violation of any recorded building lines,
restrictions or easements affecting the Premises. Such survey shall be dated no
more than thirty (30) days prior to the date of Closing and shall be certified
to have been made in accordance with minimum standards of the ALTA and ACSM.
Such commitment shall be issued by the Title Company, shall name Tenant or its
designee as the proposed insured and shall show title to the Premises in
Landlord, subject only to (i) the Permitted Title Exceptions, and (ii) other
title exceptions pertaining

                                                                              35
<PAGE>

to liens or encumbrances of a definite or ascertainable amount which may be
removed at Closing by the payment of money, but not to exceed the cash portion
of the purchase price otherwise payable to Landlord at Closing, and which
Landlord shall so remove or cause to be removed concurrently with the Closing.
In addition to the foregoing, Landlord shall remove or cause to be removed,
concurrently with the Closing, any mortgage and any other related security
instrument. Landlord shall pay all premiums, charges and costs incurred in
delivering such commitment and survey, and shall pay any state transfer tax
incurred in connection with the conveyance to Tenant of title to the Premises.
Tenant shall pay any city transfer tax incurred in connection with such
conveyance.

      32.06 Termination of Lease Upon Closing. If Tenant's option to purchase
the Premises hereunder is exercised, this Lease and all rights hereunder (except
for this Section 32.06 and all rights hereunder as otherwise expressly provided
in this Lease) shall terminate upon the Closing as provided herein, and all
rental due Landlord under this Lease shall be prorated as of the date of
Closing.

                                                                              36

                                GUARANTY OF LEASE

      THIS GUARANTY OF LEASE (hereinafter referred to as this "Guaranty") is
made as of the 11th day of April, 2003, by TITAN HOLDINGS, INC., a Delaware
corporation, having its principal place of business at 10877 Wilshire Blvd., Los
Angeles, CA 90024 hereinafter referred to as "Guarantor") to and for the benefit
of Bradley Marshall, LLC, S. Pulitzer Marshall, LLC, M. Pulitzer Marshall, LLC,
Gries Marshall, LLC, Marshall Manager, LLC and Blackwood Marshall, LLC as
tenants in common, all Delaware limited liability companies having its principal
place of business at c/o Bradley Associates, 225 North Michigan Avenue, 11th
Floor, Chicago, Illinois 60601, Attention: Sherwin Jarol (hereinafter referred
to as "Landlord").

                                    RECITALS

      A. Landlord, as landlord, and Autocam Corporation, a Michigan corporation
(hereinafter referred, to as "Tenant"), as tenant, have entered into, or are
about to enter into, a certain Lease dated as of April 11, 2003, pursuant to
which Tenant leases or will lease from Landlord certain premises commonly known
as 1511 George Brown Drive, Marshall, Michigan (the "Premises"), all as more
particularly described in said Lease (said Lease, as heretofore or hereafter
supplemented, amended, restated, renewed, extended, replaced or modified,
hereinafter referred to as the "Lease"). All capitalized terms which are not
expressly defined in this Guaranty shall have the same meanings herein as are
ascribed to such terms in the Lease.

      B. Landlord has required, as a condition to its execution and performance
of the Lease, that Guarantor execute and deliver this Guaranty of all
obligations of Tenant arising and all sums due by Tenant under the Lease for the
Term of the Lease. The execution and delivery of this Guaranty by Guarantor is a
material inducement to Landlord for the execution and performance of the Lease.

      C. Tenant is a subsidiary of Guarantor or Guarantor otherwise has a
substantial financial interest in Tenant, and Guarantor will be directly
benefited by the Lease. Accordingly, in consideration of Landlord entering into
the Lease, Guarantor has agreed to execute, deliver and perform this Guaranty.

      NOW, THEREFORE, in consideration of the Recitals set forth above and in
consideration of Landlord executing and performing its obligations under the
Lease and for other good and valuable consideration, the receipt, adequacy and
sufficiency of which are hereby acknowledged, Guarantor covenants and agrees as
follows:

      1. Recitals. The Recitals set forth above are incorporated herein and
shall be deemed terms and provisions hereof. All capitalized terms as used in
this Guaranty shall have the respective meanings ascribed to such terms in the
Lease, except as otherwise expressly provided herein.

      2. Guaranty. Guarantor absolutely, unconditionally and irrevocably
guarantees to Landlord:

         (a) The full and prompt payment when due, whether upon acceleration
or otherwise, and at all times thereafter, of any and all rentals, debts and
obligations of Tenant for the payment of money, however created, arising or
evidenced, whether direct or indirect, absolute or contingent, now or hereafter
existing, due or to become due, known or unknown to Guarantor at the time of the
execution of this Guaranty, which may now be or hereafter become

<PAGE>

due by Tenant under the Lease, including, without limitation, all Base Rent,
Impositions, late fees, interest, amounts required to discharge mechanics' and
materialmen's liens and claims therefor, and any and all other sums from time to
time becoming due from Tenant to Landlord under the Lease;

            (b) the full, complete and punctual observance, performance and
satisfaction of all covenants, terms, conditions, obligations, duties and
agreements of Tenant under the Lease; and

            (c) the payment of all Enforcement Costs.

      All amounts due and debts, liabilities and payment obligations described
in subparagraphs (a) and (c) of this Paragraph 2 are referred to herein as the
"Liabilities." All obligations described in subparagraph (b) of this Paragraph 2
are referred to herein as the "Obligations."

      3.    Landlord's Remedies.

            (a) This Guaranty is an absolute, present and continuing guaranty of
payment and performance and not merely a guaranty of collection. In the event of
any default by Tenant under the Lease, Guarantor agrees, on demand by Landlord,
to pay all Liabilities then due hereunder, regardless of any defense, right of
setoff or claim which Tenant or Guarantor may have against Landlord, unless
otherwise expressly set forth in the Lease. In the event that there shall be any
default by Tenant, Guarantor or any other party under the Lease in the due and
timely performance and observance of the Obligations or any of them after the
expiration of any cure period applicable thereto, then, in such event, Guarantor
agrees, on demand by Landlord to perform the Obligations. If Guarantor fails to
commence and pursue diligently the performance of the Obligations within five
(5) days after its receipt of written notice from Landlord demanding the
performance of Guarantor, then, either before or after pursuing any other remedy
of Landlord against Guarantor or Tenant and regardless of whether Landlord shall
ever pursue any such other remedy, Landlord shall have the right (but not the
obligation) to perform the Obligations or to call upon any other reputable
parties to perform the Obligations, and shall have the right to expend such
reasonable and necessary sums as Landlord in its discretion deems proper in
order so to complete the performance of the Obligations. All amounts required to
be paid by the terms hereof shall be included within the term "Liabilities," and
all obligations required to be performed by the terms hereof shall be included
within the term "Obligations."

            (b) Notwithstanding anything to the contrary herein contained, in
any action to enforce any of the Liabilities or Obligations, Landlord may not
proceed against Guarantor without: (i) joining Tenant in any such action; or
(ii) obtaining a judgment against Tenant; provided, however, Landlord shall have
the right to proceed against Guarantor without either joining Tenant in any such
or any other action, or obtaining a judgment against Tenant, if at the time
Landlord initiates any action against Guarantor: (A) a petition has been filed
against Tenant seeking reorganization or arrangement of Tenant under the
bankruptcy laws of the United States, as now an effect or hereafter amended, or
any state thereof (individually and collectively, "Bankruptcy Laws"); (B) Tenant
shall file a petition in bankruptcy or a petition to take advantage of any
insolvency statute, make an assignment for the benefit of creditors, make a
transfer in fraud of creditors, apply for or consent to the appointment of a
receiver of itself or of the whole or any substantial part of its property, or
file a petition or answer seeking reorganization or arrangement under any
Bankruptcy Laws; (C) a court of competent jurisdiction shall enter an order,
judgment or decree adjudicating Tenant bankrupt, or appointing a receiver

                                       2
<PAGE>

of Tenant, or of the whole or any substantial part of Tenant's property; (D)
Tenant has dissolved or ceased its legal existence; or (E) Landlord is otherwise
enjoined, restrained or unable to so join Tenant or obtain a judgment against
Tenant. Nevertheless, the maintenance of any action or proceeding by Landlord to
recover any sum or sums that may be or become due under the Lease or to secure
the performance of any of the other terms, covenants and conditions of the Lease
shall not preclude Landlord from demanding and receiving the payment of such
sums and the performance of such other terms, covenants and conditions from
Guarantor, or from thereafter instituting and maintaining subsequent actions or
proceedings for any subsequent default or defaults of Tenant under the Lease.

            (c) Guarantor does hereby consent that, without affecting the
liability of Guarantor under this Guaranty and without notice to Guarantor, time
may be given by Landlord to Tenant for payment of rent and such other sums and
performance of said other terms, covenants and conditions, or any of them, and
such time extended and indulgence granted from time to time, or Tenant may be
dispossessed or Landlord may avail itself of or exercise any or all of the
rights and remedies against Tenant provided by law or by the Lease, and may
proceed either against Tenant alone or jointly against Tenant and Guarantor.
Additionally, Landlord may proceed against Guarantor alone without either
joining Tenant or obtaining a judgment against Tenant as provided in Paragraph
3(b) hereof.

      4. No Rights to Compete with Landlord as Creditor. Guarantor does hereby
further agree that with respect to any payments made by Guarantor hereunder,
Guarantor shall not have any rights based on suretyship, subrogation or
otherwise to stand in the place of Landlord so as to compete with Landlord as a
creditor of Tenant, and Guarantor hereby waives all such rights to the fullest
extent permitted by law until such time as all Liabilities and Obligations are
paid and satisfied in full, at which time such rights shall be fully revived.

      5. No Discharge. Guarantor agrees that the obligations, covenants and
agreements of Guarantor under this Guaranty shall not be affected or impaired by
any act of Landlord, or any event or condition except the full, final and
unavoidable performance of all Obligations and payment of all Liabilities and
any other sums due hereunder. Guarantor agrees that the liability of Guarantor
hereunder shall not be discharged by, and Guarantor hereby irrevocably consents
to: (i) any subsequent change, modification or amendment of the Lease in any of
its terms, covenants and conditions, or in the Rent or any other sums payable
thereunder, or in the Term thereof, or in the Premises demised thereby (whether
said Premises be expanded, contracted, relocated, substituted or otherwise
altered), and to any assignments of the Lease and to any sublettings of the
Premises, and to any extensions or renewals of the Lease or its Term; (ii) the
renewal or extension of time for the payment of the Liabilities or performance
of the Obligations under the Lease or any other agreement relating to the
Premises; (iii) any assignment, transfer, waiver, compromise, settlement,
modification, surrender or release of Tenant's obligations under the Lease; (iv)
the existence of any defenses to enforcement of the Lease; (v) any failure,
omission, delay or inadequacy of Landlord to exercise any right or remedy
against Tenant available to Landlord pursuant to the Lease or law or in equity;
(vi) any distress or reentry by Landlord or dispossession of Tenant or any
action or remedy taken by Landlord under the Lease, or any failure to notify
Guarantor of any default by Tenant; or (vii) the existence of any setoff, claim
or counterclaim or the reduction or diminution of the Liabilities or any defense
of any kind or nature, which Guarantor may have against Tenant or which any
party has against Landlord, all whether or not Guarantor shall have had notice
or knowledge of any act or omission referred to in the foregoing clauses (i)
through (vii) inclusive of this Paragraph. Notwithstanding the foregoing or
anything else contained in this Guaranty, Guarantor is only liable to pay and
perform Liabilities and Obligations of Tenant under the Lease which remain

                                       3
<PAGE>

unpaid or not performed, as the case may be, at the time Landlord is proceeding
under this Guaranty.

      6. Application of Amounts Received. Any amounts received by Landlord from
whatsoever source on account of any Liabilities may be applied by Landlord
toward the payment of such Liabilities, and in such order of application, as
Landlord may from time to time elect.

      7. Waiver. Guarantor expressly waives: (i) notice of the acceptance by
Landlord of this Guaranty; (ii) notice of the existence, creation, payment or
nonpayment of the Liabilities; (iii) presentment, demand, notice of dishonor,
protest and all other notices whatsoever, except as otherwise specifically set
forth in this Guaranty; and (iv) any failure by Landlord to inform Guarantor of
any facts Landlord may now or hereafter know about Tenant, the Lease or the
Premises, it being understood and agreed that Guarantor has and will maintain
personal knowledge of and is familiar with Tenant's financial condition and
business affairs and has the ability to influence Tenant's decision-making
processes, and that Landlord has no duty so to inform, and that Guarantor is
fully responsible for being and remaining informed by, Tenant of all
circumstances bearing on the Lease and this Guaranty. No modification or waiver
of any of the provisions of this Guaranty will be binding upon Landlord except
as expressly set forth in a writing duly signed and delivered on behalf of
Landlord.

      8. Enforcement Costs. If the Lease or this Guaranty is placed in the hands
of an attorney for enforcement or collection through any legal proceeding, and
Landlord is determined in such legal proceeding to be the prevailing party,
then, Guarantor shall pay to Landlord upon demand all attorneys' fees, costs and
expenses, including, without limitation court costs and filing fees, and all
other costs and expenses reasonably incurred by Landlord in connection with such
legal proceeding (all of which are referred to herein as "Enforcement Costs") in
addition to all other amounts due hereunder. In the event Guarantor is
determined to be the prevailing party in any such legal proceeding, then
Landlord shall pay Guarantor, upon demand, all attorneys' fees, costs and
expenses, including, without limitation, court costs and filing fees, and all
other costs and expenses reasonably incurred in connection therewith.

      9. Transfer of Lease. Notwithstanding any assignment or transfer of the
Lease or any interest therein by Landlord, for collateral purposes or otherwise,
each and every immediate and successive assignee, transferee or other successor
in interest with respect to Landlord's interest under the Lease shall, to the
extent of the interests assigned or transferred, be entitled to the benefits of
this Guaranty to the same extent as if such assignee or transferee were
Landlord.

      10. Governing Law; Interpretation. This Guaranty shall be governed by the
laws of the State of Michigan without reference to the conflicts of law
principles of that State. The headings of Paragraphs in this Guaranty are for
convenience only and shall not be construed in any way to limit or define the
content, scope or intent of the provisions hereof. As used in this Guaranty, the
singular shall include the plural, and masculine, feminine and neuter pronouns
shall be fully interchangeable where the context so requires. If this Guaranty
is executed by more than one person or entity, then references to "Guarantor"
herein shall be deemed to refer to each such person or entity and the liability
of each such person or entity shall be joint and several, and the release by
Landlord of any of them shall not release or affect in any manner the
obligations of any other of them, and this Guaranty shall not be revoked,
discharged or impaired as to any such persons or entities by reason of the death
or incapacity or insolvency of any other of them. If any provision of this
Guaranty, or any paragraph, sentence, clause, phrase or

                                       4
<PAGE>

word, or the application thereof, in any circumstances, is adjudicated by a
court of competent jurisdiction to be invalid, the validity of the remainder of
this Guaranty shall be construed as if such invalid part were never included
herein. Time is of the essence of this Guaranty. All payments to be made
hereunder shall be made in currency and coin of the United States of America
which is legal tender for public and private debts at the time of payment.

      11. Entire Agreement. This Guaranty constitutes the entire agreement
between Guarantor and Landlord with respect to the subject matter hereof and
supersedes all prior such agreements and understandings, both written and oral.
This Guaranty may not be modified or amended except by a written instrument
signed by Landlord and Guarantor. If this Guaranty is executed in several
counterparts, each of those counterparts shall be deemed an original, and all of
them together shall constitute one and the same instrument.

      12. Subordinated Debt. Any indebtedness of Tenant to Guarantor, other than
that advanced from a senior, secured, institutional, commercial lender to
Guarantor and re-advanced to Tenant by Guarantor (the "Subordinated Debt") now
or hereafter existing is hereby subordinated to the Liabilities. Guarantor
agrees that, until the full, final and unavoidable payment of the Liabilities,
Guarantor will not seek, accept or retain for Guarantor's own account, any
payment from Tenant on account of the Subordinated Debt. Any payments to
Guarantor on account of the Subordinated Debt shall be collected and received by
Guarantor in trust for Landlord and shall be paid over to Landlord on account of
the Liabilities without impairing or releasing the obligations of Guarantor
hereunder.

      13. Payment of Indebtedness/Release of Guaranty. Release of this Guaranty,
if it occurs, shall not affect, in any respect, the Lease.

      14. Successors and Assigns.

          (a) This Guaranty shall bind Guarantor and the heirs, assigns,
successors, executors, administrators and legal and personal representatives of
Guarantor; provided that any assignment or transfer of this Guaranty by
Guarantor shall in no manner operate to relieve or release Guarantor from any of
its obligations or liabilities under this Guaranty. Notwithstanding anything
contained in the immediately preceding sentence to the contrary, an assignment
or transfer of this Guaranty shall operate to relieve and release Guarantor from
its obligations and liabilities under the Guaranty provided that, prior to such
assignment or transfer, Guarantor delivers to Landlord financial statements and
other reasonable financial information regarding such assignee or transferee, as
the case may be, which statements and information are certified to be true and
correct by the chief financial officer of such assignee or transferee, as the
case may be, and which evidence that the tangible net worth of such assignee or
transferee, as the case may be, is no less than Guarantor's tangible net worth
as of the date of this Guaranty. Regardless of whether this Guaranty is executed
by more than one person or entity, it is agreed that the undersigned's liability
hereunder is several and independent of any other guaranties or other
obligations at any time in effect with respect to the Indebtedness, the
Obligations or any part thereof and that each Guarantor's liability hereunder
may be enforced regardless of the existence, validity, enforcement or
nonenforcement of any such other guaranties or other obligations.

            (b) This Guaranty shall inure to the benefit of and be enforceable
by Landlord and its successors and assigns, the officers, agents, employees,
partners, directors and shareholders of each of them, each of their respective
successors and assigns, and each

                                       5
<PAGE>

present or subsequent mortgagee of the Premises and its successors and assigns
(all such persons and entities shall be "Indemnified Parties" under the Lease).

      15.   Agent for Service of Process; Certain Waivers by Guarantor.

            (a) Guarantor hereby submits to personal jurisdiction in the State
of Michigan for the enforcement of this Guaranty, whether or not Guarantor shall
be then physically present, residing or doing business within the State of
Michigan, and waives any and all personal rights to object to such jurisdiction
for the purposes of litigation to enforce this Guaranty. In the event such
litigation is commenced at any time when Guarantor is not permanently domiciled
in the State of Michigan or does not have a registered agent in the State of
Michigan, Guarantor agrees that service of process may be made and personal
jurisdiction over Guarantor obtained by service of a copy of the summons,
complaint and other pleadings required to commence such litigation upon
Guarantor's appointed agent for service of process in the State of Michigan or
any other State in which Guarantor may be incorporated, or as service of process
on corporations may otherwise be made pursuant to Michigan law or the law of
such other State, as the case may be and in each case with a copies to Tenant as
indicated below.

      Guarantor hereby agrees that an action, suit or proceeding to enforce this
Guaranty may be brought in either the state circuit court located in the County
in which the Premises are located, or the United States District Court for the
District in which the Premises are located; provided, however, that the
provisions of this Paragraph shall not be deemed to preclude Landlord from
filing any such action, suit or proceeding in any other appropriate forum.

            (b) Guarantor hereby waives the right to trial by jury in any action
or proceeding that hereafter may be instituted in respect of the Lease or this
Guaranty.

      16.   Financial Statements. Guarantor represents that it has provided
Landlord with true and complete financial statements (the "Financial
Statements") setting forth the financial condition of Guarantor as of the date
specified in such statements. Upon Landlord's written request, Guarantor shall
promptly furnish Landlord with a written certification from an executive
officer, manager, or partner of Guarantor describing in reasonable detail any
material adverse change in the financial condition of Guarantor from that set
forth in the respective Financial Statements or stating that there has been no
such change. Upon Landlord's prior written request, Guarantor shall also
promptly furnish to Landlord such other recent financial statements and other
relevant financial information relative to and evidencing Guarantor's financial
condition, which financial statements and financial information shall be
certified as true, correct and complete by an executive officer, manager or
partner of Guarantor.

      17.   Notices. Any notice, demand, service of process or other
communication which is given hereunder shall be in writing and shall be deemed
given if and when personally delivered, or on the first business day after being
deposited with a nationally recognized overnight carrier, addressed to the
intended recipient at its address set forth below or to such other address as
such intended recipient may have designated by notice furnished in accordance
