     IN  CONSIDERATION  of and in order to  induce  MICHIGAN  NATIONAL  BANK,  a
national  banking  association,  with  offices  located at 27777  Inkster  Road,
Farmington Hills, Ml 48333-9065 (the "Bank"),  to loan money,  extend credit to,
or to purchase,  accept or discount  notes,  instruments  or other  evidences of
indebtedness of or from, and generally to engage in financial accommodations and
to  do  business  with  CENTURY  SUPPLY  CORP.,  a  Michigan   corporation  (the
"Borrower"),  the undersigned,  jointly and severally (hereinafter  individually
and collectively referred to as the "Guarantor"), hereby covenant and agree with
the Bank as follows:

     1. Guarantor unconditionally guarantees to Bank the full and prompt payment
when due of all  Indebtedness  (as  hereinafter  defined) of Borrower due and to
become due to the Bank. The Bank may have immediate  recourse against  Guarantor
for the full and  immediate  payment of the  Indebtedness,  or any part thereof,
which  has not been  paid in full at  maturity  (whether  at fixed  maturity  or
maturity  accelerated by reason of the Borrower's default under the terms of any
instrument   governing  the   Indebtedness   or  any   agreement   securing  the
Indebtedness).

     2. The term "Indebtedness"  shall mean all indebtedness,  liabilities,  and
obligations of Borrower to Bank, of every kind,  nature and description,  direct
or  indirect,  absolute or  contingent,  now  existing or  hereafter  arising or
acquired,  now due or as may hereafter become due, and whether joint, several or
joint and several,  including,  without limitation, the covenants and agreements
contained  in this  Guaranty  and  every  promissory  note,  guaranty,  security
agreement,  loan agreement,  " swap agreement" (within the meaning of the United
States  Bankruptcy  Code of  1978,  as  amended,  11 USC 101 et  sea.)  or other
document,  instrument  or  agreement,  now  existing  or  hereafter  executed or
delivered  to the Bank,  with  respect to any  existing or future  loan,  "swap"
(within the meaning of the  Bankruptcy  Code of 1978, as amended,  11 USC 101 et
seq.),  deposit  account  overdraft  or  other  financial  accommodation  to the
Borrower,  with such  interest,  fees and  charges  as are  provided  for in the
evidence(s))   thereof  or  by  applicable   law,  all   renewals,   extensions,
modifications,  or refinancings  thereof and all costs,  expenses and reasonable
attorneys' and  paralegals'  fees  (including  without  limitation the allocated
expenses of in-house attorneys and paralegals) incurred to disburse, administer,
enforce or collect any  Indebtedness,  to protect,  maintain  or  liquidate  any
security therefor or to defend, pay or compromise any claim or action related to
or arising therefrom (" Indebtedness" ) .

     3. This is a guarantee  of payment  and not of  collection,  and  Guarantor
agrees that the Bank shall not be obligated prior to seeking recourse against or
receiving payment from Guarantor,  to do any of the following (although the Bank
may do so, in whole or in part, at its sole option),  the  performance  of which
are hereby unconditionally waived by Guarantor:

     (a)  Take any steps to collect the  Indebtedness  from  Borrower or to file
          any claim of any kind against Borrower; or

     (b)  Take any steps to enforce,  accept,  perfect the Bank's  interest  in,
          foreclose upon, or realize on any collateral  security for the payment
          of the Indebtedness or any other guaranty of the Indebtedness; or

     (c)  In any other respect exercise any diligence  whatever in collecting or
          attempting to collect the Indebtedness by any means.

     4. Guarantor's  liability for payment of the Indebtedness shall be absolute
and unconditional,  and nothing except final and full payment to the Bank of all
of the Indebtedness shall operate to discharge  Guarantor's liability under this
Guaranty. Accordingly, Guarantor unconditionally and irrevocably waives each and
every  defense  which  under  principles  of guaranty  or  suretyship  law would
otherwise  operate to impair or diminish  the  liability  of  Guarantor  for the
Indebtedness. Without limiting the generality of the foregoing waiver, Guarantor
agrees that none of the following acts, omissions, or occurrences shall diminish
or  impair  the  liability  of  Guarantor  in any  respect  (all of which  acts,
omissions or occurrences may be done without notice to Guarantor):

     (a)  Any extension,  modification,  indulgence,  compromise, settlement, or
          variation of any of the terms of the Indebtedness;

     (b)  The discharge or release of any  obligations of the Borrower or of any
          other person now or hereafter  liable on the Indebtedness by reason of
          bankruptcy or insolvency laws or otherwise;

     (c)  The  acceptance or release by the Bank of any  collateral  security or
          any other Guaranty,  or any  settlement,  compromise or extension with
          respect to any collateral security or other Guaranty;

     (d)  The application or allocation by the Bank of payments, collections, or
          credits on the  Indebtedness or any other  obligations of the Borrower
          to the Bank;


                                       
<PAGE>


     (e)  The creation of any new Indebtedness by Borrower;

     (f)  The  making of  demand,  or  absence  of  demand,  for  payment of the
          Indebtedness, or giving, or failing to give, any notice of dishonor or
          protest, or any other notice.

     5. Guarantor further unconditionally and irrevocably waives:

     (a)  All rights  Guarantor may have, at law or in equity,  to seek or claim
          subrogation,  contribution,  indemnification,  or any  other  form  of
          reimbursement  from the Borrower by virtue of any  payment(s)  made to
          Bank under this  Guaranty or otherwise  until the  Indebtedness  shall
          have been fully and finally paid;

     (b)  Any acceptance of this Guaranty;

     (c)  Any set-offs or  counterclaims  against the Bank which would impair or
          affect the Bank's rights against Guarantor;

     (d)  Any notice of the disposition of any collateral security and any right
          to object to the commercial  reasonableness  of the disposition of any
          such collateral security;

     (e)  Any  defenses  related  to  the  validity  or  enforceability  of  any
          documentation  executed - by Borrower or by  Guarantor  in  connection
          with the Indebtedness.

     6.  Guarantor  acknowledges  and agrees with Bank that if Bank shall at any
time be  required  to  return  or  restore  to  Borrower  or to any  trustee  in
bankruptcy,  any  payment(s)  made upon the  Indebtedness,  this guaranty  shall
continue in full force and effect or shall be fully  reinstated  as the case may
be, and Guarantor's obligation to Bank under this guaranty shall be increased by
the amount of any such payment(s) upon the Indebtedness as Bank shall be obliged
to return or restore,  plus interest thereon at the default rate provided in the
evidence of Indebtedness  applicable to any such payment(s) from the date(s) the
payment(s)  upon the  Indebtedness  was  originally  made.  Guarantor  agrees to
indemnify and hold Bank  harmless  from and against any and all costs,  fees and
expenses including, without limitation, reasonable attorneys' fees and allocated
costs of in-house counsel, in connection with Bank's defending any preference or
fraudulent  conveyance  claim or action  brought  against Bank in any bankruptcy
proceeding concerning Borrower.

     7. This Guaranty  shall inure to the benefit of the Bank and its successors
and assigns,  including every holder of any of the Indebtedness here guaranteed.
In the event that any person other than the Bank shall become a holder of any of
the Indebtedness, each reference to the Bank shall be construed to refer to each
such holder.

     8. This Guaranty  shall be binding upon  Guarantor and  Guarantor's  heirs,
successors,  and estate  representatives,  and shall  continue  in effect  until
Guarantor  delivers to the Bank at the above  address,  thirty (30) days advance
written  notice of  termination,  provided that this Guaranty  shall continue in
full force and effect  thereafter with respect to all  Indebtedness in existence
on the effective date of such termination (including all extensions and renewals
thereof and all subsequently  accruing interest and other charges thereon) until
all such Indebtedness shall be fully and finally paid to Bank.

     9.  Guarantor  represents  and  warrants  to the Bank  that  all  financial
statements  concerning  Guarantor's  financial condition are true and correct in
all material  respects as of the date of such statements and, if such statements
are not current, that there has been no material adverse change in the financial
condition of Guarantor  from the date of such  statement to the date of delivery
of this  Guaranty to the Bank.  Guarantor  acknowledges  that in accepting  this
Guaranty the Bank has relied upon such financial statements and Guarantor agrees
to provide the Bank with a statement of Guarantor's current financial condition,
in form  satisfactory  to Bank,  at least  annually and within  thirty (30) days
after Bank's request.

     10.  This  Guaranty  and all rights and  obligations  hereunder,  including
matters of construction,  validity,  and  performance,  shall be governed by the
laws of the State of Michigan,  and Guarantor  consents to both jurisdiction and
venue in the Michigan courts.

     11.  The term  "Guarantor"  shall  mean  all and  each  one of the  persons
executing  this Guaranty  agreement and their  obligations  to the Bank shall be
joint and several.

     12.  Notwithstanding   anything  to  the  contrary  contained  herein,  the
liability of each Guarantor named below shall be UNLIMITED.

     13. The  performance  of  Guarantor's  obligations  under this  Guaranty is
secured by a Stock Pledge Agreement dated October 27, 1993.

     14.  This  Guaranty   agreement  and  the  terms  and   provisions  of  any
agreement(s)  described  in  Paragraph 13 above  constitute  Guarantor's  entire
agreement with Bank, and there are no other agreements,  either written or oral,
which modify or supplement  Guarantor's said agreement(s)  with Bank.  Guarantor
acknowledges  and agrees  with Bank that this  Guaranty  cannot be  modified  or
amended in any respect except by an additional  writing signed by both Guarantor
and Bank.
