                              --------------------------

Date of Issuance:  October 15, 1999                                  $30,000,000


     J.L. French Automotive Castings, Inc., a Delaware corporation (the
"COMPANY"), hereby promises to pay to the order of Tower Automotive, Inc. the
principal amount of $30,000,000 together with interest thereon calculated from
the date hereof in accordance with the provisions of this Note.  For purposes
hereof, "NOTES" shall mean this Note and any Note issued upon transfer of all or
any portion of this Note.

          1.   PAYMENT OF INTEREST.

          (a)  INTEREST RATE.  Interest shall accrue at the rate of seven and
one-half percent (7.50%)   per annum (computed on the basis of a 360-day year
and the actual number of days elapsed in any year) on the unpaid principal
amount of this Note outstanding from time to time, or (if less) at the highest
rate then permitted under applicable law.

          (b)  PAYMENT.  The Company shall pay to the holder of this Note all
accrued interest on the last day of each December, March, June and September,
beginning December 31,



1999; PROVIDED, HOWEVER, that, if a Constraining Circumstance exists and is
continuing on such payment date, only those funds which could be paid without a
Constraining Circumstance occurring and continuing shall be used to pay interest
to the holders of the Notes.  Unless prohibited under applicable law, any
accrued interest which is not paid on the date on which it is due and payable
shall bear interest at the same rate at which interest is then accruing on the
principal amount of this Note until such interest is paid.  Any accrued interest
which for any reason has not theretofore been paid shall be paid in full on the
date on which the final principal payment on this Note is made.  Interest shall
accrue on any principal payment due under this Note until such time as payment
therefor is actually delivered to the holder of this Note.

          2.   PAYMENT OF PRINCIPAL ON NOTE.

          (a)  SCHEDULED PAYMENTS.  The Company shall pay the principal amount
of this Note (or if the principal amount then outstanding on this Note is less
than such amount, the remaining principal then outstanding), together with all
accrued and unpaid interest on October 15, 2009.  The obligation of the Company
to make payment on the foregoing date is hereinafter referred to as the
"SCHEDULED PAYMENT."

          (b)  PREPAYMENTS.  The Company may, at any time and from time to time
without premium or penalty, prepay all or any portion of the outstanding
principal amount of the Notes; provided that (A) such prepayment is not
prohibited by the provisions of paragraph 3 hereof and (B) the Company has paid
all interest on the Notes accrued through the immediately preceding scheduled
interest payment date.  In connection with each prepayment of principal
hereunder, the Company shall also pay all accrued and unpaid interest on the
principal amount of the Notes being repaid.  To exercise its option to make any
optional prepayment hereunder, the Company must give the holder hereof written
notice of such prepayment not less than five days and not more than thirty days
prior to the date fixed for such prepayment, specifying the date of proposed
prepayment, the aggregate principal amount of all Notes to be prepaid on such
date, the aggregate amount of interest to be paid with such aggregate prepayment
of principal on such date, the principal amount of this Note to be prepaid on
such date, and the amount of interest to be paid with such prepayment of
principal on this Note.   The holder of this Note may elect to convert all or a
portion of the principal amount of this Note rather than receive such
prepayment.  In the event of such election, the holder shall deliver to the
Company in person or by registered or certified mail, return receipt requested,
such holder's Note on or prior to the date of prepayment and such conversion
shall be effected in accordance with the terms of paragraph 6 hereof.

          3.   SUBORDINATION.

          (a)  EXTENT OF SUBORDINATION.

               (i)   The Subordinated Obligations are expressly "subordinate and
junior in right of payment" (as that phrase is defined in paragraph (ii) below)
to all Senior Obligations.


                                          2


               (ii)  "SUBORDINATE AND JUNIOR IN RIGHT OF PAYMENT" means that:

               (A)   no part of the Subordinated Obligations shall have any
          claim to the assets or securities of the Company on a parity with or
          prior to the claim of the Senior Obligations; and

               (B)   unless and until the Senior Obligations have been paid in
          full in cash and the Commitments under the Senior Credit Agreement
          have been terminated, without the express prior written consent of the
          Administrative Agent, the holders of this Note will not take, demand
          or receive from the Company, and the Company will not make, give or
          permit, directly or indirectly, by set-off, redemption,  purchase or
          in any other manner, any payment of or security for the whole or any
          part of the Subordinated Obligations, including, without limitation,
          any guarantee, letter of credit or similar credit support facility to
          support payment of the Subordinated Obligations; PROVIDED, HOWEVER,
          except upon the occurrence and during the continuance of a payment
          default under the Senior Credit Agreement or an Event of Default (as
          defined in the Senior Credit Agreement), the Company may make, and the
          holder of this Note may receive, scheduled payments on account of
          interest on this Note in accordance with the terms thereof as in
          effect on the date hereof; and

               (C)   the holder of this Note will not accelerate for any reason
          payment of any amount owing under this Note; PROVIDED; HOWEVER, that
          upon the occurrence of an acceleration of all amounts owed under the
          Senior Credit Agreement the holder of this Note may accelerate the
          Schedule Payment, together with any accrued and unpaid interest.

          (b)  ADDITIONAL PROVISIONS CONCERNING SUBORDINATION

               (i)   Upon the occurrence of any Insolvency Event:

               (A)   all Senior Obligations shall be paid in full in cash before
          any payment or distribution is made with respect to the Subordinated
          Obligations; and

               (B)   any payment or distribution of assets or securities of the
          Company, whether in cash, property or securities, to which the holder
          of this Note would be entitled except for the provisions hereof, shall
          be paid or delivered by the Company, or any receiver, trustee in
          bankruptcy, liquidating trustee, disbursing agent or other Person
          making such payment or distribution, directly to the Administrative
          Agent, for the account of the Senior Lenders, to the extent necessary
          to pay in full in cash all Senior Obligations, before any payment or
          distribution shall be made to the holders of this Note.


                                          3


               (ii)  If any payment or distribution, whether consisting of
money, property or securities, shall be collected or received by the
Subordinated Lender or any other holder of this Note in respect of the
Subordinated Obligations, except payments permitted to be made at the time of
payment as provided in paragraph 3(a)(ii)(B), the Subordinated Lender or such
holder forthwith shall deliver the same to the Administrative Agent for the
account of the Senior Lenders, in the form received, duly indorsed to the
Administrative Agent, if required, to be applied to the payment or prepayment of
(or, in the case of unmatured obligations in respect of letters of credit, as
collateral for) the Senior Obligations until the Senior Obligations are paid in
full in cash.  Until so delivered, such payment or distribution shall be held in
trust by the Subordinated Lender or such holder as the property of the Senior
Lenders, segregated from other funds and property held by the Subordinated
Lender or such holder.

          (c)  SUBROGATION.   Subject to the payment in full in cash of the
Senior Obligations (other than any indemnification obligations under the Senior
Credit Agreement not due and payable), the Subordinated Lender shall be
subrogated to the rights of the Senior Lenders to receive payments or
distributions of assets or securities of the Company in respect of the Senior
Obligations until the Senior Obligations (other than any indemnification
obligations under the Senior Credit Agreement not due and payable) shall be paid
in full in cash.  For the purposes of such subrogation, payments or distribution
to the Administrative Agent, for the account of the Senior Lenders, of any
money, property or securities to which the Subordinated Lender would be entitled
except for the provisions hereof shall be deemed, as between the Company and its
creditors other than the Senior Lenders and the Subordinated Lender, to be a
payment by the Company to or on account of Subordinated Obligations, it being
understood that the provisions hereof are, and are intended solely, for the
purpose of defining the relative rights of the Subordinated Lender, on the one
hand, and the Senior Lenders, on the other hand.

          (d)  The subordination provisions of this Note are not intended to
impact the rights of the holder of this Note to convert this Note into common
equity of the Company in accordance with Section 6 hereof.

          4.   EVENTS OF DEFAULT.

          (a)  DEFINITION.  For purposes of this Note, an Event of Default shall

maturity or otherwise) the full amount of any principal payment on any Note;

               (ii)  the Company fails to perform or observe any other provision
contained in the Notes, and such failure is not cured within 30 days after the

                                          4


               (iii) any representation or warranty, or any writing furnished by
the Company to any holder of the Notes, is false or misleading in any material
respect on the date made or furnished;

               (iv)  the Company or any Subsidiary makes an assignment for the

generally as they become due; or an order, judgment or decree is entered
adjudicating the Company or any Subsidiary bankrupt or insolvent; or any order
for relief with respect to the Company or any Subsidiary is entered under the

administrative or governmental body.

          (b)  CONSEQUENCES OF EVENTS OF DEFAULT.

               (i)   Subject to the provisions of paragraph 3 (including

               (ii)  Subject to the provisions of paragraph 3 (including

          5.   RESTRICTION ON TRANSFER.  No holder of any Note shall sell,
transfer, assign, pledge or otherwise dispose of (whether with or without
consideration and whether voluntarily or involuntarily or by operation of law)
any interest in a Note, other than to a wholly owned Subsidiary of such holder
without the prior written consent of the Company.

          6.   CONVERSION.

          (a)  CONVERSION PROCEDURE.

               (i)   At any time and from time to time prior to the payment of
this Note in full, the holder of this Note may convert all or any portion of the
outstanding principal amount of this Note and any accrued but unpaid interest
thereon into a number of shares of the Conversion Stock determined by dividing
the principal amount and any accrued but unpaid interest designated by such
holder to be converted, by the Conversion Price then in effect.

               (ii)  Except as otherwise expressly provided herein, each
conversion of this Note shall be deemed to have been effected as of the close of
business on the date on which this Note has been surrendered for conversion at
the principal office of the Company.  At such time as such conversion has been
effected, the rights of the holder of this Note as such holder to the extent of
the conversion shall cease, and the Person or Persons in whose name or names any
certificate or certificates for shares of Conversion Stock are to be issued upon
such conversion shall be deemed to have become the holder or holders of record
of the shares of Conversion Stock represented thereby.

               (iii) Notwithstanding any other provision hereof, if a conversion
of any portion of this Note is to be made in connection with a registered public
offering or a sale of the Company, the conversion of any portion of this Note
may, at the election of the holder hereof, be conditioned upon the consummation
of the public offering or the sale of the Company, in which case such conversion
shall not be deemed to be effective until the consummation of such transaction.


                                          6


               (iv)  As soon as possible after a conversion has been effected
(but in any event within five business days in the case of clause (A) below),
the Company shall deliver to the converting holder:

               (A)   a certificate or certificates representing the number of
     shares of Conversion Stock issuable by reason of such conversion in such
     name or names and such denomination or denominations as the converting
     holder has specified; and

               (B)   a new Note representing any portion of the principal amount
     which was represented by the Note surrendered to the Company in connection
     with such conversion but which was not converted.

               (v)   The issuance of certificates for shares of Conversion Stock
upon conversion of this Note shall be made without charge to the holder hereof
for any issuance tax in respect thereof or other cost incurred by the Company in
connection with such conversion and the related issuance of shares of Conversion
Stock.  Upon conversion of this Note, the Company shall take all such actions as
are necessary in order to insure that the Conversion Stock issuable with respect
to such conversion shall be validly issued, fully paid and nonassessable.

               (vi)  The Company shall not close its books against the transfer
of Conversion Stock issued or issuable upon conversion of this Note in any
manner which interferes with the timely conversion of this Note.  The Company
shall assist and cooperate with any holder of this Note required to make any
governmental filings or obtain any governmental approval prior to or in
connection with the conversion of this Note (including, without limitation,
making any filings required to be made by the Company).

               (vii) The Company shall at all times reserve and keep available
out of its authorized but unissued shares of Conversion Stock, solely for the
purpose of issuance upon the conversion of the Note, such number of shares of
Conversion Stock issuable upon the conversion of all outstanding Notes.  All
shares of Conversion Stock which are so issuable shall, when issued, be duly and
validly issued, fully paid and nonassessable and free from all taxes, liens and
charges.  The Company shall take all such actions as may be necessary to assure
that all such shares of Conversion Stock may be so issued without violation of
any applicable law or governmental regulation or any requirements of any
domestic securities exchange upon which shares of Conversion Stock may be listed
(except for official notice of issuance which shall be immediately delivered by
the Company upon each such issuance).

          (b)  CONVERSION PRICE.  The initial Conversion Price shall be $5896.75
(the "CONVERSION PRICE").

          (c)  SUBDIVISION OR COMBINATION OF COMMON STOCK.  If the Company at
any time subdivides (by any stock split, stock dividend or otherwise) one or
more classes of its outstanding shares of Common Stock into a greater number of
shares, the Conversion Price in effect immediately


                                          7


prior to such subdivision shall be proportionately reduced, and if the Company
at any time combines (by reverse stock split or otherwise) one or more classes
of its outstanding shares of Common Stock into a smaller number of shares, the
Conversion Price in effect immediately prior to such combination shall be
proportionately increased.

          (d)  REORGANIZATION, RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE.
Any recapitalization, reorganization, reclassification, consolidation, merger,
sale of all or substantially all of the Company's assets or other transaction,
which in each case is effected in such a manner that holders of Common Stock are
entitled to receive (either directly or upon subsequent liquidation) stock,
securities or assets with respect to or in exchange for Common Stock is referred
to herein as an "Organic Change."  Prior to the consummation of any Organic
Change, the Company shall make lawful and adequate provision (in form and
substance satisfactory to the holders of a majority of the principal amount of
the Notes then outstanding) to insure that each of the holders of the Notes
shall thereafter have the right to acquire and receive, in lieu of or addition
to (as the case may be) shares of Conversion Stock immediately theretofore
acquirable and receivable upon the conversion of such holder's Note, such shares
of stock, securities or assets as may be issued or payable with respect to or in
exchange for the number of shares of Conversion Stock immediately theretofore
acquirable and receivable upon conversion of such holder's Note had such Organic
Change not taken place.  In any such case, appropriate provision (in form and
substance satisfactory to the holders of a majority of the principal amount of
the Notes then outstanding) shall be made with respect to such holder's rights
and interests to insure that the provisions of this paragraph 6 shall thereafter
be applicable in relation to any shares of stock, securities or assets
thereafter deliverable upon the conversion of the Notes (including, in the case
of any such consolidation, merger or sale in which the successor entity or
purchasing entity is other than the Company, an immediate adjustment of the
Conversion Price to the value for the Common Stock reflected by the terms of
such consolidation, merger or sale, and a corresponding immediate adjustment in
the number of shares of Conversion Stock acquirable and receivable upon
conversion of the Notes, if the value so reflected is less than the Conversion
Price in effect immediately prior to such consolidation, merger or sale).  The
Company shall not effect any such consolidation, merger or sale, unless prior to
the consummation thereof, the successor entity (if other than the Company)
resulting from consolidation or merger or the entity purchasing such assets
assumes by written instrument (in form reasonably satisfactory to the holders of
a majority of the principal amount of the Notes then outstanding), the
obligation to deliver to each such holder such shares of stock, securities or
assets as, in accordance with the foregoing provisions, such holder may be
entitled to acquire.

          (e)  NOTICES.

               (i)   Immediately upon any adjustment of the Conversion Price,
the Company shall send written notice thereof to the holder of this Note,
setting forth in reasonable detail and certifying the calculation of such
adjustment.

               (ii)  In order to permit the holder of this Note to exercise its
conversion rights set forth in this paragraph 6, the Company shall send written
notice to the holder of this Note


                                          8


at least 20 days prior to the date on which the Company closes its books or
takes a record (A) with respect to any dividend or distribution upon the Common
Stock, (B) with respect to any pro rata subscription offer to holders of Common
Stock or (C) for determining rights to vote with respect to any Organic Change,
dissolution or liquidation.

          (f)  The Company shall also give at least 20 days prior written notice
of the date on which any Organic Change, dissolution or liquidation shall take
place.
