person with a security  interest in your property has,  among other rights,  the
right to sell your property under certain  circumstances.  You agree to promptly
pay all taxes,  fees,  and charges  concerning the purchase or ownership of your
property.  If you do not,  we can do so, and you agree to  reimburse  us for all
amounts we pay,  plus  interest  on those  amounts at the same rate of  interest
charged to the borrower.

                           OWNERSHIP OF YOUR PROPERTY

     You  promise  us that you own your  property  free of any and all claims by
anyone other than you or us, that no one other than you owns your property,  and
that all of the owners of your property have signed this agreement.

                             CARE OF YOUR PROPERTY

     You agree that we will have taken  reasonable  care of your  property if we
treat it in the same way as we treat our own property of the same kind, but that
we are not  responsible  for taking any steps  necessary  to preserve or protect
your rights in your property against any prior or other parties.  You agree that
if your property is of a kind which can be registered in our name, we can at any
time  register  your  property  in our name or in the name of someone  who holds
securities for us, and you agree to sign all documents which we think are needed
to do so.

                 AUTHORITY TO EXERCISE RIGHTS IN YOUR PROPERTY

     In general,  you agree that as long as we have possession of your property,
we may do anything  concerning  your  property that you could do, but we are not
required to do so. Without  limiting this general power,  we, or if we have your
property registered in the name of someone other than you that person, will have
all of your rights in your property  (such as the right to vote  securities  and
the right to receive dividends or interest) but neither we nor such other person
are  required  to  exercise  any of those  rights  on your  behalf.  If you have
previously  given authority to exercise rights in your property to someone other
than us, by signing this  agreement you are revoking that  authority  previously
given.  You  agree  that we can  apply  any  money,  such as cash  dividends  or
interest,  which  we  receive  from  your  property  to pay any  loans  or other
obligations  secured  by your  property,  applying  this  money in any  order we
choose,  whether or not the loans or other obligations  secured by your property
are then due.

                              MARGIN REQUIREMENTS

     You understand  and agree that if your property is "margin  stock," as that
term is defined in  Regulation U of Federal  Reserve Board  Regulations,  and is
pledged to us to directly or  indirectly  secure the purchase or carrying of any
margin  stock,  we can not at  anytime  allow the unpaid  balance of  borrower's
loan(s) to exceed the maximum  loan value  prescribed  under  Regulation  U. You
agree  that if at any time  the loan  value of your  margin  stock  exceeds  the
maximum loan value allowed under  Regulation U, you will  immediately  reduce or
cause to be reduced  the unpaid  balance of the loan(s)  directly or  indirectly
secured by your margin stock, or will immediately pledge to us additional margin
stock,  so that the maximum  loan value  prescribed  under  Regulation  U is not
exceeded.

                             SALE OF YOUR PROPERTY

     You agree that we can sell your  property  if any of the  following  events
occur:

     1.   Any loan or other obligation owed us by you or by the borrower, either
          now or in the  future,  is not paid or  performed  when the payment or
          performance is due;

     2.   You or the  borrower  violate  the  provisions  of this  or any  other
          agreement with us, either now or in the future;

     3.   You or the borrower die;

     4.   You or the borrower make any false or misleading  statement  about any
          important matter in an agreement or application with us.

     Unless your property is likely to speedily  decline in value or is property
commonly  sold on a recognized  market,  we will give you at least  fifteen (15)
days written notice before selling your property,  sending the notice by regular
mail to your  current  address  shown in our  records.  Upon your receipt of our
notice that we intend to sell your property, you can redeem it by paying in full
all loans,  obligations,  and costs secured by your  property,  prior to sale of
your property.  Upon our sale of your property,  we will apply the sale proceeds
to pay any attorney  fees and other costs and  expenses we have  incurred on the
loans or obligations  secured by your  property,  and then to the loans or other
obligations  secured by your  property,  in any order we  choose.  If there is a
surplus  remaining after applying the proceeds from sale of your property to our
fees,  costs,  and  expenses  and to the loans and  obligations  secured by your
property, we will promptly return the surplus to you.

     You  understand  that our  ability  to sell your  property  may be  limited
because of special laws and regulations applying to the sale of securities.  You
agree to do anything we think is needed to help us sell your  property,  whether
needed  because of these special laws and  regulations  or for any other reason,
and you agree that we will have a continuing power of attorney to sign your name
on any document  necessary to sell your  property if any of the events listed in
1. through 5. above occur.

                         CHANGE OF ADDRESS/NOTICE TO US

     If your address changes, you agree to promptly notify us in writing of your
new  address.  Any notice you give us must be in writing and must be sent to our
address shown in this agreement.

                          NO NOTICE OR LOSS OF RIGHTS

     You agree that we may, but are not  required to,  notify you if any loan or
obligation  secured by your property is not paid or  performed,  and that we can
exercise any of our rights  without  losing any other rights against you or your
property. You agree that we can do any of the following without notifying you or
losing any rights against you or your property:


                                       2
<PAGE>


     1.   Allow  additional  time  for  payment  or  otherwise  amend  any  loan
          agreements with the borrower;

     2.   Delay exercising any rights against you, the borrower,  your property,
          and any other person or property;

     3.   Fail to protect or enforce our interest in any of your property.

                        ATTORNEY'S FEES AND COURT COSTS

     If we hire an attorney to enforce or defend our rights in your property, to
perform  any legal  services  in  connection  with the  holding  or sale of your
property,  or in  connection  with the  loans  or  obligations  secured  by your
property, you agree to pay us reasonable attorney fees and any court costs which
we have to pay.

                                OTHER AGREEMENTS

     Any changes in this  agreement  must be in writing and signed by you and by
us. This agreement is the complete  agreement  between you and us concerning the
security  interest in your property  given by this  agreement and supersedes all
prior  agreements,  written or oral. If any part of this agreement is determined
to be invalid,  the rest of this agreement will remain in effect.  All questions
about this agreement will be decided according to Michigan law.

                             AGREEMENT TERMINATION

     This  agreement  will end when we return all of your property  described in
the  beginning of this  agreement.  We will return your  property to you at such
time as neither you nor the borrower is indebted or otherwise obligated to us.

                              YOUR RESPONSIBILITY

     You and everyone  else signing this  agreement  will be,  individually  and
together,  liable  under it, and you  understand  that we can sue you to enforce
this  agreement  even if we do not sue anyone else. You agree that you have read
and understand and agree to be bound by all of the provisions of this agreement,
and that we have provided you with an  opportunity to review this agreement with
legal counsel of your choice before signing this agreement.
