                                   (CONTINUED)

                                                                          PAGE 2


writing, (a) any breach or violation of any Environmental Laws, (b) any use,
generation, manufacture, storage, treatment, disposal, release or threatened
release of any Hazardous Substance on, under, about or from the Property by any
prior owners or occupants of the Property, or (c) any actual or threatened
litigation or claims of any kind by any person relating to such matters; and (3)
Except as previously disclosed to and acknowledged by Lender in writing, (a)
neither Grantor nor any tenant, contractor, agent or other authorized user of

release any Hazardous Substance, on under about or from the Property; and (b)
any such activity shall be conducted in compliance with all applicable federal,
state, and local laws, regulations and ordinances, including without limitation
all Environmental Laws. Grantor authorizes Lender and its agents to enter upon
the Property to make such inspections and tests, at Grantor's expense, as Lender
may deem appropriate to determine compliance of the Property with this section
of the Mortgage. Any inspections or tests made by Lender shall be for Lender's
purposes only and shall not be construed to create any responsibility or
liability on the part of Lender to Grantor or to any other person. The
representations and warranties contained herein are based on Grantor's due
diligence in investigating the Property for Hazardous Substances. Grantor hereby
(1) releases and waives any future claims against Lender for indemnity or
contribution in the event Grantor becomes liable for cleanup or other costs
under any such laws; and (2) agrees to indemnify and hold harmless Lender
against any and all claims, losses, liabilities, damages, penalties, and
expenses which Lender may directly or indirectly sustain or suffer resulting
from a breach of this section of the Mortgage or as a consequence of any use,
generation, manufacture, storage, disposal, release or threatened release
occurring prior to Grantor's ownership or interest in the Property, whether or
not the same was or should have been known to Grantor. The provisions of this
section of the Mortgage, including the obligation to indemnify, shall survive
the payment of the Indebtedness and the satisfaction and reconveyance of the
lien of this Mortgage and shall not be affected by Lender's acquisition of any
interest in the Property, whether by foreclosure or otherwise.

NUISANCE, WASTE. Grantor shall not cause, conduct or permit any nuisance nor
commit, permit, or suffer any stripping of or waste on or to the Property or any
portion of the Property. Without limiting the generality of the foregoing,
Grantor will not remove, or grant to any other party the right to remove, any
timber, minerals (including oil and gas), coal, clay, scoria, soil, gravel or
rock products without Lender's prior written consent.

REMOVAL OF IMPROVEMENTS. Grantor shall not demolish or remove any Improvements
from the Real Property without Lender's prior written consent. As a condition to
the removal of any Improvements, Lender may require Grantor to make arrangements
satisfactory to Lender to replace such Improvements with Improvements of at
least equal value.

LENDER'S RIGHT TO ENTER. Lender and Lender's agents and representatives may
enter upon the Real Property at all reasonable times (a) attend to Lender's
interests, (b) inspect the Property for purposes of Grantor's compliance with
the terms and conditions of this Mortgage, (c) appraise the property, (d)
investigate whether the property is a site or source of environmental
contamination, or (e) remove to remediate any environmental contamination.
Without limiting the foregoing, Lender shall have the right to conduct and
submit to appropriate governmental agencies a "baseline environmental
assessment" of the property within the meaning of section 20101 of the Michigan
Natural Resources and Environmental Protection Act, MCL section 324.20101, as it
shall be amended from time to time. If, at the time of the appraisal,
investigation, assessment, removal, or remediation, there shall have occurred
and be continuing an Event of Default, then all costs and expenses of the
appraisal, investigation, assessment, removal or remediation, shall be subject
to the "Expenditures by Lender" section of this Mortgage. Grantor shall execute
any consultant contract, waste manifest, notice, and other documents that Lender
requests to enable Lender to take or conduct any action or activity contemplated
by this paragraph, if Grantor is given a reasonable opportunity to negotiate the
terms of the contract, manifest, notice, or other document.

COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS. Grantor shall promptly comply with
all laws, ordinances, and regulations, now or hereafter in effect, of all
governmental authorities applicable to the use or occupancy of the Property,
including without limitation, the Americans With Disabilities Act. Grantor may
contest in good faith any such law, ordinance, or regulation and withhold
compliance during any proceeding, including appropriate appeals, so long as
Grantor has notified Lender in writing prior to doing so and so long as, in
Lender's sole opinion, Lender's interests in the Property are not jeopardized.
Lender may require Grantor to post adequate security or a surety bond,
reasonably satisfactory to Lender, to protect Lender's interest.

DUTY TO PROTECT. Grantor agrees neither to abandon or leave unattended the
Property. Grantor shall do all other acts, in addition to those acts set forth
above in this section, which from the character and use of the Property are
reasonably necessary to protect and preserve the Property.

CONSTRUCTION LOAN. If some or all of the proceeds of the loan creating the
Indebtedness are to be used to construct or complete construction of any
Improvements on the Property, the Improvements shall be completed no later than
the maturity date of the Note (or such earlier date as Lender may reasonably
establish) and Grantor shall pay in full all costs and expenses in connection
with the work. Lender will disburse loan proceeds under such terms and
conditions as Lender may deem reasonably necessary to insure that the interest
created by this Mortgage shall have priority over all possible liens, including
those of material suppliers and workmen. Lender may require, among other things,
that disbursement requests be supported by receipted bills, expense affidavits,
waivers of liens, construction progress reports, and such other documentation as
Lender may reasonably request.

TAXES AND LIENS. The following provisions relating to the taxes and liens on the
Property are part of this Mortgage:

PAYMENT. Grantor shall pay when due (and in all events prior to delinquency) all
taxes, payroll taxes, special taxes, assessments, water charges and sewer
service charges levied against or on account of the Property, and shall pay when
due all claims for work done on or for services rendered or material furnished
to the Property. Grantor shall maintain the Property free of any liens having
priority over or equal to the interest of Lender under this Mortgage, except for
those liens specifically agreed to in writing by Lender, and except for the lien
of taxes and assessments not due as further specified in the Right to Contest
paragraph.

RIGHT TO CONTEST. Grantor may withhold payment of any tax, assessment, or claim
in connection with a good faith dispute over the obligation to pay, so long as
Lender's interest in the Property is not jeopardized. If a lien arises or is
filed as a result of nonpayment, Grantor shall within fifteen (15) days after
the lien arises or, if a lien is filed, within fifteen (15) days after Grantor
has notice of the filing, secure the discharge of the lien, or if requested by
Lender, deposit with Lender cash or a sufficient corporate surety bond or other
security satisfactory to Lender in an amount sufficient to discharge the lien
plus any costs and reasonable attorneys' fees, or other charges that could
accrue as a result of a foreclosure or sale under the lien. In any contest,
Grantor shall defend itself and Lender and shall satisfy any adverse judgment
before enforcement against the Property. Grantor shall name Lender as an
additional obligee under any surety bond furnished in the contest proceedings.

EVIDENCE OF PAYMENT. Grantor shall upon demand furnish to Lender satisfactory
evidence of payment of the taxes or assessments and shall authorize the
appropriate governmental official to deliver to Lender at any time a written
statement of the taxes and assessments against the Property.

NOTICE OF CONSTRUCTION. Grantor shall notify Lender at least fifteen (15) days
before any work is commenced, any services are furnished, or any materials are
supplied to the Property, if any mechanic's lien, materialmen's lien, or other
lien could be asserted on account of the work, services, or materials. Grantor
will upon request of Lender furnish to Lender advance assurances satisfactory to
Lender that Grantor can and will pay the cost of such improvements.

PROPERTY DAMAGE INSURANCE. The following provisions relating to insuring the
Property are a part of this Mortgage:

MAINTENANCE OF INSURANCE. Grantor shall procure and maintain policies of fire
insurance with standard extended coverage endorsements on a replacement basis
for the full insurable value covering all Improvements on the Real Property in
an amount sufficient to avoid application of any coinsurance clause, and with a
standard mortgagee clause in favor of Lender. Grantor shall also procure and
maintain comprehensive general liability insurance in such coverage amounts as
Lender may request with Lender being named as additional insureds in such
liability insurance policies. Additionally, Grantor shall maintain such other
insurance, including but not limited to hazard, business interruption and boiler
insurance as Lender may require. Policies shall be written by such insurance
companies and in such form as may be reasonably acceptable to Lender. Grantor
shall deliver to Lender certificates of coverage from each insurer containing a
stipulation that coverage will not be cancelled or diminished without a minimum
of thirty (30) days' prior written notice to Lender

                                   (CONTINUED)

                                                                          PAGE 4


and not containing any disclaimer of the insurer's liability for failure to give
such notice. Each insurance policy also shall include an endorsement providing
that coverage in favor of Lender will not be impaired in any way by any act,
omission or default of Grantor or any other person. Should the Real Property be
located in an area designated by the Director of the Federal Emergency
Management Agency as a special flood hazard area, Grantor agrees to obtain and
maintain Federal Flood Insurance, if available, within 45 days after notice is
given by Lender that the Property is located in a special flood hazard area, for
the full unpaid principal balance of the loan and any prior liens on the
property securing the loan, up to the maximum policy limits set under the
National Flood Insurance Program, or as otherwise required by Lender, and to
maintain such insurance for the term of the loan.

APPLICATION OF PROCEEDS. Grantor shall promptly notify Lender of any loss or
damage to the Property. Lender may make proof of loss if Grantor fails to do so
within fifteen (15) days of the casualty. Whether or not Lender's security is
impaired, Lender may, at Lender's election, receive and retain the proceeds of
any insurance and apply the proceeds to the reduction of the Indebtedness,
payment of any lien affecting the Property, or the restoration and repair of the
Property. If Lender elects to apply the proceeds to restoration and repair,
Grantor shall repair or replace the damaged or destroyed Improvements in a
manner satisfactory to Lender. Lender shall, upon satisfactory proof of such
expenditure, pay or reimburse Grantor from the proceeds for the reasonable cost
of repair or restoration if Grantor is not in default under this Mortgage.

Any proceeds which have not been disbursed within 180 days after their receipt
and which Lender has not committed to the repair or restoration of the Property
shall be sued first to pay any amount owing to Lender under this Mortgage, then
to pay accrued interest, and the remainder, if any, shall be applied to the
principal balance of the Indebtedness. If Lender holds any proceeds after
payment in full of the Indebtedness, such proceeds shall be paid to Grantor as
Grantor's interests may appear.

GRANTOR'S REPORT ON INSURANCE. Upon request of Lender, however not more than
once a year, Grantor shall furnish to Lender a report on each existing policy of
insurance showing: (1) the name of the insurer; (2) the risks insured; (3) the
amount of the policy; (4) the property insured, the then current replacement
value of such property, and the manner of determining that value; and (5) the
expiration date of the policy. Grantor shall, upon request of Lender, have an
independent appraiser satisfactory to Lender determine the cash value
replacement cost of the Property.

LENDER'S EXPENDITURES. If any action or proceeding is commenced that would
materially affect Lender's interest in the Property or if Grantor fails to
comply with any provision of this Mortgage or any Related Documents, including
but not limited to Grantor's failure to discharge or pay when due any amounts
Grantor is required to discharge or pay under this Mortgage or any Related
Documents, Lender on Grantor's behalf may (but shall not be obligated to) take
any action that Lender deems appropriate, including but not limited to
discharging or paying all taxes, liens, security interests, encumbrances and
other claims, at any time levied or placed on the Property and paying all costs
for insuring, maintaining and preserving the Property. All such expenditures
incurred or paid by Lender for such purposes will then bear interest at the rate
charged under the Note from the date incurred or paid by Lender to the date of
repayment by Grantor. All such expenses will become a part of the Indebtedness
and, at Lender's option, will (A) be payable on demand; (B) be added to the
balance of the Note and be apportioned among and be payable with any installment
payments to become due during either (1) the term of any applicable insurance
policy; or (2) the remaining term of the Note; or (C) be treated as a balloon
payment which will be due and payable at the Note's maturity. The Mortgage also
will secure payment of these amounts. Such right shall be in addition to all
other rights and remedies to which Lender may be entitled upon Default.

WARRANTY; DEFENSE OF TITLE. The following provisions relating to ownership of
the Property are a part of this Mortgage:

TITLE. Grantor warrants that: (a) Grantor hold good and marketable title of
record to the Property in fee simple, free and clear of all liens and
encumbrances other than those set forth in the Real Property description or in
any title insurance policy, title report, or final title opinion issued in favor
of, and accepted by, Lender in connection with this Mortgage, and (b) Grantor
has the full right, power, and authority to execute and deliver this Mortgage to
Lender.

DEFENSE OF TITLE. Subject to the exception in the paragraph above, Grantor
warrants and will forever defend the title to the Property against the lawful
claims of all persons. In the event any action or proceeding is commenced that
questions Grantor's title or the interest of Lender under this Mortgage, Grantor
shall defend the action at Grantor's expense. Grantor may be the nominal party
in such proceeding, but Lender shall be entitled to participate in the
proceeding and to be represented in the proceeding by counsel of Lender's own
choice, and Grantor will deliver, or cause to be delivered, to Lender such
instruments as Lender may request from time to time to permit such
participation.

the Property complies with all existing applicable laws, ordinances, and

a part of this Mortgage:

PROCEEDINGS. If any proceeding in condemnation is filed, Grantor shall promptly
notify Lender in writing, and Grantor shall promptly take such steps as may be
necessary to defend the action and obtain the award. Grantor may be the nominal
party in such proceeding, but Lender shall be entitled to participate in the
proceeding and to be represented in the proceeding by counsel of its own choice,
and Grantor will deliver or cause to be delivered to Lender such instruments and
documentation as may be requested by Lender from time to time to permit such
participation.

APPLICATION OF NET PROCEEDS. If all or any part of the Property is condemned by
eminent domain proceedings or by any proceeding or purchase in lieu of
condemnation, Lender may at its election require that all or any portion of the
net proceeds of the award be applied to the Indebtedness or the repair or
restoration of the Property. The net proceeds of the award shall mean the award
after payment of all reasonable costs, expenses, and attorneys' fees incurred by
Lender in connection with the condemnation.

provisions relating to governmental taxes, fees and charges are a part of this

any portion of the Indebtedness or on payments of principal and interest made by
Grantor.

SUBSEQUENT TAXES. If any tax to which this section applies is enacted subsequent
to the date of this Mortgage, this event shall have the same effect as an Event
of Default, and Lender may exercise any or all of its available remedies for an
Event of Default as provided below unless Grantor either (1) pays the tax before
it becomes delinquent, or (2) contests the tax as provided above in the Taxes
and Liens section and deposits with Lender cash or a sufficient corporate surety
bond or other security satisfactory to Lender.

FURTHER ASSURANCES. At any time, and from time to time, upon request of Lender,
Grantor will make, execute and deliver, or will cause to be made, executed or

Commercial Code. Without limiting those rights and remedies, Lender may, at its

                                   (CONTINUED)

                                                                          PAGE 8


COLLECT RENTS. Lender shall have the right, without notice to Grantor, to take
possession of the Property and collect the Rents, including amounts past due and
unpaid, and apply the net proceeds, over and above Lender's costs, against the
Indebtedness. In furtherance of this right, Lender may require any tenant or
other user of the Property to make payments of rent or use fees directly to
Lender. If the Rents are collected by Lender, then Grantor irrevocably
designates Lender as Grantor's attorney-in-fact to endorse instruments received
in payment thereof in the name of Grantor and to negotiate the same and collect
the proceeds. Payments by tenants or other users to Lender in response to
Lender's demand shall satisfy the obligations for which the payments are made,
whether or not any proper grounds for the demand existed. Lender may exercise
its rights under this subparagraph either in person, by agent, or through a
receiver.

APPOINT RECEIVER. Any failure of Grantor to pay any taxes assessed against the
Property or to pay any installment of those taxes or to pay any insurance
premium upon any policy covering any property located upon the Property shall
constitute waste and shall entitle Lender to the appointment by a court of
competent jurisdiction of a receiver of the Property for the purpose of
preventing the waste, except that no receiver may be appointed for any dwelling
house or farm occupied by any owner of it as the owner's home or farm or for any
store or other business property having an assessed valuation of $7,500 or less.
Subject to the order of the court, the receiver may collect the rents and income
from the Property and shall exercise control over the Property to the extent
ordered by the court. A court may also appoint a receiver for the Property in
any other circumstances permitted by law. Lender shall have the right to have a
receiver appointed to take possession of all or any part of the Property, with
the power to protect and preserve the Property and apply the proceeds, over and
above the cost of the receivership, against the Indebtedness. The receiver may
serve without bond if permitted by law. Lender's right to the appointment of a
receiver shall exist whether or not the apparent value of the Property exceeds
the Indebtedness by a substantial amount. Employment by Lender shall not
disqualify a person from serving as a receiver.

JUDICIAL FORECLOSURE. Lender may obtain a judicial decree foreclosing Grantor's
interest in all or any part of the Property.

NONJUDICIAL SALE. Lender may sell, release and convey the Real Property at
public sale and sign and deliver to the purchasers at the sale good and
sufficient deeds of conveyance, paying any surplus funds, after payment in full
of the sums then due under this Mortgage and the expenses of the sale, including
attorney fees as provided by law, to Grantor, all in accordance with applicable
law.

WARNING. THIS MORTGAGE CONTAINS A POWER OF SALE, AND, UPON DEFAULT, MAY BE
FORECLOSED BY ADVERTISEMENT. IN FORECLOSURE BY ADVERTISEMENT, NO HEARING IS
INVOLVED AND THE ONLY NOTICE REQUIRED IS TO PUBLISH NOTICE IN A LOCAL NEWSPAPER
AND TO POST A COPY OF THE NOTICE ON THE PROPERTY.

WAIVER. If this Mortgage is foreclosed by advertisement, Grantor hereby
voluntarily and knowingly waives all rights under the Constitution and laws of
the State of Michigan and Constitution and laws of the United States to all
notice and a hearing in connection with the above-mentioned foreclosure by
advertisement, except as set forth in the Michigan statute providing for
foreclosure by advertisement.

DEFICIENCY JUDGMENT. If permitted by applicable law, Lender may obtain a
judgment for any deficiency remaining in the Indebtedness due to Lender after
application of all amounts received from the exercise of the rights provided in
this section.

TENANCY AT WILL. If Grantor remains in possession of the Property after Lender
or the purchaser at a foreclosure sale of the Property become lawfully entitled
to possession of the Property, the Grantor shall become a tenant at will of
Lender or the purchaser of the Property and shall, at the option of the person
lawfully entitled to possession, either (1) pay a reasonable rental for the use
of the Property or (2) vacate the Property immediately upon the demand of the
person lawfully entitled to possession.

OTHER REMEDIES. Lender shall have all other rights and remedies provided in this
Mortgage or the Note or available at law or in equity.

                                   (CONTINUED)

                                                                          PAGE 9


SALE OF THE PROPERTY. To the extent permitted by applicable law, Grantor hereby
waives any and all right to have the Property marshalled. In exercising its
rights and remedies, Lender shall be free to sell all or any part of the
Property together or separately, in one sale or by separate sales and Grantor
waives Grantor's rights under MCLA Section 600.3224 to have separate parcels
sold separately and to have no more parcels than necessary sold. Lender shall be
entitled to bid at any public sale on all or any portion of the Property.

NOTICE OF SALE. Lender shall give Grantor reasonable notice of the time and
place of any public sale of the Personal Property or of the time after which any
private sale or other intended disposition of the Personal Property is to be
made. Reasonable notice shall mean notice given at least ten (10) days before
the time of the sale or disposition. Any sale of the Personal Property may be
made in conjunction with any sale of the Real Property.

ELECTION OF REMEDIES. Election by Lender to pursue any remedy shall not exclude
pursuit of any other remedy, and an election to make expenditures or to take
action to perform an obligation of Grantor under this Mortgage, after Grantor's
failure to perform, shall not affect Lender's right to declare a default and
exercise its remedies. Nothing under this Mortgage or otherwise shall be
construed so as to limit or restrict the rights and remedies available to Lender
following an Event of Default, or in any way to limit or restrict the rights and
ability of Lender to proceed directly against Grantor and/or against any other
co-maker, guarantor, surety or endorser and/or to proceed against any other
collateral directly or indirectly securing the Indebtedness. After the date that
payment of the Indebtedness secured by this Mortgage has been accelerated by
Lender, acceptance by Lender of any amount(s) paid by or on behalf of Grantor
which is less than the full unpaid balance of the Indebtedness, including
without limitation all accrued interest, late charges and other amounts due
Lender under this Mortgage, shall not be deemed a waiver of default or
acceleration, but shall be credited toward the unpaid balance of the
Indebtedness, unless Lender shall specifically agree in writing to waive any
such default or acceleration or both.

ATTORNEYS' FEES; EXPENSES. If Lender institutes any suit or action to enforce
any of the terms of this Mortgage, Lender shall be entitled to recover its
reasonable attorneys' fees. Whether or not any court action is involved, and to
the extent not prohibited by law, all reasonable expenses Lender incurs that in
Lender's opinion are necessary at any time for the protection of its interest or
the enforcement of its rights shall become a part of the Indebtedness payable on
demand and shall bear interest at the Note rate from the date of the expenditure
until repaid. Expenses covered by this paragraph include, without limitation,
however subject to any limits under applicable law, Lender's reasonable
attorneys' fees and Lender's legal expenses whether or not there is a lawsuit,
including reasonable attorneys' fees and expenses for bankruptcy proceedings
(including efforts to modify or vacate any automatic stay or injunction),
appeals, and any anticipated post-judgment collection services, the cost of
searching records, obtaining title reports (including foreclosure reports),
surveyors' reports, and appraisal fees and title insurance, to the extent
permitted by applicable law. Grantor also will pay any court costs, in addition
to all other sums provided by law.

NOTICES. Any notice required to be given under this Mortgage, including without
limitation any notice of default and any notice of sale shall be given in
writing, and shall be effective when actually delivered, when actually received
by telefacsimile (unless otherwise required by law), when deposited with a
nationally recognized overnight courier, or, if mailed, when deposited in the
United States mail, as first class, certified or registered mail postage
prepaid, directed to the address shown near the beginning of this Mortgage. All
copies of notices of foreclosure from the holder of any lien which has priority
over this Mortgage shall be sent to Lender's address, as shown near the
beginning of this Mortgage. Any party may change its address for notices under
this Mortgage by giving formal written notice to the other parties, specifying
that the purpose of the notice is to change the party's address. For notice
purposes, Grantor agrees to keep Lender informed at all times of Grantor's
current address. Unless otherwise provided or required by law, if there is more
than one Grantor, any notice given by Lender to any Grantor is deemed to be
notice given to all Grantors.

Commencement," is attached to this Mortgage and by this reference is made a part

this Mortgage unless such waiver is given in writing and signed by Lender. No
delay or omission on the part of Lender in exercising any right shall operate as
a waiver of such right or any other right. A waiver by Lender of a provision of
this Mortgage shall not prejudice or constitute a waiver of Lender's right
otherwise to demand strict compliance with that provision or any other provision
of this Mortgage. No prior waiver by Lender, nor any course of dealing between
Lender and Grantor, shall constitute a waiver of any of Lender's rights or of
any of Grantor's obligations as to any future transactions. Whenever the consent
of Lender is required under this Mortgage, the granting of such consent by
Lender in any instance shall not constitute continuing consent to subsequent
instances where such consent is required and in all cases such consent may be
granted or withheld in the sole discretion of Lender.

SEVERABILITY. If a court of competent jurisdiction finds any provision of this
Mortgage to be illegal, invalid, or unenforceable as to any circumstance, that
finding shall not make the offending provision illegal, invalid, or
unenforceable as to any other circumstance. If feasible, the offending provision
shall be considered modified so that it becomes legal, valid and enforceable. If
the offending provision cannot be so modified, it shall be considered deleted
from this Mortgage. Unless otherwise required by law, the illegality,
invalidity, or unenforceability of any provision of this Mortgage shall not
affect the legality, validity or enforceability of any other provision of this
Mortgage.

MERGER. There shall be no merger of the interest or estate created by this
Mortgage with any other interest or estate in the Property at any time held by
or for the benefit of Lender in any capacity, without the written consent of
Lender.

transfer of Grantor's interest, this Mortgage shall be binding upon and inure to
the benefit of the parties, their successors and assigns. If ownership of the
Property becomes vested in a person other than Grantor, Lender, without notice
to Grantor, may deal with Grantor's successors with reference to this Mortgage
and the Indebtedness by way of forbearance or extension without releasing
Grantor from the obligations of this Mortgage or liability under the
Indebtedness.

Mortgage.
