Attention: Mr. Richard R. Chrysler

Dear Mr. Chrysler:

     This letter  constitutes  an  agreement  by and between  COMERICA  BANK,  a
Michigan banking corporation (herein called "Bank"), and the borrowers listed in
attached  Schedule 1 (collectively,  "Borrowers" and  individually  "Borrower"),
pertaining  to certain  loans and other  credit  which Bank has made or may from
time to time hereafter make available to Borrowers.

     In  consideration of all present and future loans and credit made available
by Bank to Borrowers,  and all present and future  liabilities,  obligations and
indebtedness of Borrowers to Bank,  howsoever  created,  evidenced,  existing or
arising, whether direct or indirect,  absolute or contingent,  joint or several,
now  or  hereafter  existing  or  arising,  or  due  or to  become  due  (herein
collectively called the "Liabilities"), Borrowers covenant and agree as follows:

     1. Each loan or other  extension  of credit made by Bank to or otherwise in
favor of Borrowers  shall be  evidenced  by and subject to a promissory  note or
other agreement or evidence of indebtedness  acceptable to Bank and executed and
delivered by Borrowers to Bank (any and all notes,  instruments,  documents  and
agreements at any time evidencing,  governing, securing or otherwise relating to
any of the Liabilities are herein collectively called the "Loan Documents").

     2. So long as Bank shall have any commitment or obligation, if any, to make
or extend loans or other credit to or in favor of Borrowers, and thereafter,  so
long as any Liabilities remain unpaid and/or outstanding, Borrowers covenant and
agree that they shall:

     (a)  Furnish,  or cause to be  furnished,  to Bank,  (i) within one hundred
          twenty  (120)  days  after  and as of the end of each  fiscal  year of
          Borrowers, audited consolidated and consolidating financial statements
          of JPE, Inc. and its consolidated subsidiaries, in each case certified
          by independent certified public accountants satisfactory to Bank; (ii)
          within  forty  five  (45) days  after and as of the end of each  month
          unaudited consolidated and consolidating  financial statements of JPE,
          Inc., and its consolidated  subsidiaries,  as of the end of such month
          and for the portion of the fiscal year of Borrowers  then  ending,  in
          each case,  certified  by a duly  authorized  officer of  Borrowers on
          behalf of  Borrowers;  (iii) on or before  December  31 of each  year,
          annual  financial  projections for Borrowers for the next fiscal year;
          and (iv)  within  twenty  (20)  days  after  and as of the end of each
          month, an accounts  receivable  aging,  an accounts  payable aging, an
          inventory report, and a borrowing base report; and (v) promptly,  such
          other information and reports as Bank may reasonably request from time
          to time or as may be required under any of the Loan Documents.  All of
          such  financial  statements  and other reports and  information  to be
          furnished  to Bank  hereunder,  to the  extent  applicable,  should be
          prepared in accordance with generally accepted  accounting  principles
          consistently  applied ("GAAP"),  and all such financial statements and
          other  information and reports to be furnished to Bank pursuant to the
          provisions hereof shall be in form and detail reasonably  satisfactory
          to Bank.

     (b)  Promptly inform Bank of the occurrence of any event of default, or any
          condition or event which,  with the giving of notice or the passage of
          time, or both,  would  constitute an event of default under any of the
          Liabilities  or Loan  Documents,  or of any  condition  or event which
          would  reasonably be expected to have a material  adverse  effect upon
          any Borrower's business, properties, financial condition or ability to
          comply with its  obligations  hereunder or otherwise in respect of any
          of the Liabilities.

     (c)  Maintain all of their principal bank accounts with the Bank.

     (d)  Pay to Bank  quarterly  in  arrears a  facility  fee with  respect  to
          Borrowers'  working capital line of credit in an amount equal to three
          eighths of one percent (3/8%) per annum of the average daily amount by
          which $30,000,000  exceeds advances and letters of credit  outstanding
          under the working capital line of credit.  The fee shall be calculated
          on the  basis of a year of 360  days,  for the  actual  number of days
          elapsed.

     3. Any failure by Borrowers to fully observe,  perform or otherwise  comply
with any of the covenants or agreements of Borrowers set forth in this Agreement
shall  constitute an event of default under the  Liabilities,  and Bank shall be
entitled to exercise any and all rights and  remedies  available to or otherwise
conferred  upon  Bank as a  result  thereof,  whether  by  agreement,  by law or
otherwise.

     4. Borrowers hereby  acknowledge and agree that Borrowers'  compliance with
the terms and  conditions  set forth  herein,  and the absence of any default by
Borrowers in the observance or performance of any of the covenants or agreements
of Borrowers hereunder, shall not in any way limit, restrict or otherwise affect
or impair  Bank's  right or ability to deem itself to be insecure or make demand
for payment of any or all of the  Liabilities  which may be on a demand basis at
any time in Bank's  sole and  absolute  discretion,  with or  without  reason or
cause,  and the existence of any default  hereunder shall not be the sole reason
or basis for  enabling  Bank to deem  itself to be  insecure  or make demand for
payment of all or any part of such Liabilities.

     5.  Borrowers  shall pay to Bank on the date of  execution  of this  letter
agreement a closing fee equal to $563,000. Such fee shall be deemed fully earned
upon execution of this letter agreement and shall be  non-refundable;  provided,
however,  if (a) the Dayton Parts,  Inc.  operation is sold on or before May 27,
2000, and the credit  facilities have not been terminated  before such time (and
no  demand  for  payment  thereunder  has been  made and no  default  thereunder
occurred and is continuing),  or (b) Borrowers obtain cash equity  contributions
after the date of execution of this letter  agreement,  then upon payment to the
Bank of the proceeds of the sale of the Dayton  Parts  operation or the proceeds
of such cash equity contributions,  Bank shall refund to the Borrowers an amount
equal  to one  percent  (1%) of the  amount  of such  net  proceeds  applied  to
permanent  reduction of the Liabilities,  multiplied by a fraction the numerator
of which is the  number of days  from the date of  application  of the  proceeds
until May 27, 2000 and the denominator of which is 365.

     6. No forbearance on the part of the Bank in enforcing any of its rights or
remedies  under this  Agreement  or any other Loan  Document,  nor any  renewal,
extension or rearrangement of any payment or covenant to be made or performed by
Borrowers  hereunder or any such other Loan Document,  shall constitute a waiver
of any of the terms of this Agreement or such Loan Document or of any such right
or remedy.

     7. This  Agreement  shall be  governed  by and  construed  and  enforced in
accordance with the laws of the State of Michigan.

     8. Except to the extent expressly stated herein to the contrary,  where the
character  or amount of any asset or  liability  or item of income or expense is
required to be determined or other accounting computation is required to be made
for  purposes  of this  Agreement,  it shall be done in  accordance  with  GAAP.
Furthermore,  all accounting  terms not  specifically  defined in this Agreement
shall be construed in accordance with GAAP.

     9. Borrowers  agree that it will pay upon demand all  reasonable  costs and
expenses in connection with the preparation of this Agreement and any other Loan
Documents  contemplated  hereby,  including,   without  limitation,   reasonable
attorneys' fees and disbursements of counsel for the Bank.

     10.  BORROWERS  AND BANK  ACKNOWLEDGE  THAT THE RIGHT TO TRIAL BY JURY IS A
CONSTITUTIONAL  ONE, BUT THAT IT MAY BE WAIVED. EACH PARTY, AFTER CONSULTING (OR
HAVING HAD THE  OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR CHOICE,  KNOWINGLY
AND VOLUNTARILY,  AND FOR THEIR MUTUAL BENEFIT, WAIVE ANY RIGHT TO TRIAL BY JURY
IN THE EVENT OF LITIGATION  REGARDING THE  PERFORMANCE OR ENFORCEMENT  OF, OR IN
ANY WAY RELATED TO, THIS AGREEMENT OR THE LIABILITIES.

     11. The obligations of the Borrowers under this Agreement are the joint and
several obligations of the Borrowers.

     12. This Agreement  shall inure to the benefit of and shall be binding upon
the  parties  hereto and their  respective  successors  and  assigns;  provided,
however,  that  Borrowers  shall not assign or transfer  any of their  rights or
obligations  hereunder or otherwise in respect of any of the Liabilities without
the prior written consent of Bank.

     13. The Bank agrees that it will not disclose  without the prior consent of
Borrowers (other than to Bank's  employees,  its subsidiaries or to its auditors
or  counsel)  any  information  with  respect to  Borrowers  which is  furnished
pursuant to the Loan  Documents;  provided  that the Bank may  disclose any such
information  (a) as has  become  generally  available  to the public or has been
lawfully obtained by Bank from any third party under no duty of  confidentiality
to Borrowers,  (b) as may be required or appropriate in any report, statement or
testimony submitted to, or in respect to any inquiry,  by, any municipal,  state
or federal  regulatory body having or claiming to have  jurisdiction  over Bank,
including  the Board of  Governors of the Federal  Reserve  System of the United
States,  the Office of the  Comptroller  of the Currency or the Federal  Deposit
Insurance Corporation or similar organizations  (whether in the United States or
elsewhere) or their successors, (c) as may be required or appropriate in respect
to any summons or subpoena or in connection with any litigation, (d) in order to
comply with any law, order,  regulation or ruling applicable to Bank, and (e) to
any  transferee  or assignee or to any  participant  of, or with respect to, the
Loan Documents.

     14. To the extent any provision of any Loan Document is in express conflict
with the terms of this  letter  agreement,  the terms of this  letter  agreement
shall control. If the foregoing is acceptable to Borrowers, please indicate with
the authorized signature of Borrowers as provided below.
