     2.   THE INDEBTEDNESS: Revolving Credit

     2.1  The Bank agrees to lend to Company at any time and from
time to time from the effective date hereof until but not
including the Maturity Date, sums not to exceed TWELVE MILLION
DOLLARS ($12,000,000.00), in aggregate principal amount at any
one time outstanding. The borrowing hereunder shall be evidenced
by a Revolving Credit Note to Bank (herein called "Revolving
Credit Note") in form similar to that annexed hereto as Exhibit
"A" under which advances, repayments and readvances may be made,
subject to the terms and conditions of this Agreement.

     2.2  The Revolving Credit Note shall mature on the Maturity
Date, and the respective Advances from time to time outstanding
thereunder shall bear interest at the Applicable Interest Rate.
At the time of each Advance, Company may select the Applicable
Interest Rate; provided, however, that interest shall be payable
at the Prime-based Rate in the event and so long as Company shall
not have elected another Applicable Interest Rate.  Interest
shall be payable quarterly on the unpaid balance of the Prime-based 
Advances from time to time outstanding on the last day of
each calendar quarter.  Interest on each Eurodollar-based Advance
shall be payable on the last day of the Interest Period
applicable thereto and if such Interest Period is longer than
three months, interest shall be payable at intervals of three
months from the first day thereof.  In the event and so long as
Company shall be in default under a Eurodollar-based Advance,
interest shall be payable at the greater of (i) 2% over the
Eurodollar-based Rate applicable thereto, or (ii) 2% over the
Prime-based Rate, until the Interest Period applicable thereto
shall expire, and thereafter the interest shall be payable at the
rate of 2% over the Prime-based Rate.  In the event and so long
as Company shall be in default under a Prime-based Advance,
interest shall be payable at 2% over the Prime-based Rate.

     2.3  Interest on Prime-based Advances and the facility fee
shall be computed on the basis of a 360 day year and assessed for
the actual number of days elapsed.  Interest on Eurodollar-based
Advances shall be computed on the basis of a 360 day year and
assessed for the actual number of days of the Interest Period
applicable thereto but not including the last day thereof.

     2.4  Bank shall not be obligated to make any Advance under
this Agreement unless Company shall have first filed with Bank a
Request for Advance executed by an authorized officer of Company.
Each Request for Advance shall set forth:

     (a)  the proposed date of Advance;

     (b)  whether the Advance is to be a Eurodollar-based Advance
          or a Prime-based Advance, provided that at no time
          shall more than five (5) Eurodollar-based Advances be
          outstanding at any time;

     (c)  the principal amount of such Advance which, in the case
          of a Eurodollar-based Advance shall be in an amount not
          less than $1,500,000 or any $150,000 increment thereof
          and in the case of a Prime-based Advance shall be in an
          amount not less than $500,000 or any $100,000 increment
          thereof; and

     (d)  in the case of a Eurodollar-based Advance, the duration
          of the Interest Period applicable thereto.

     2.5  Company may prepay all or part of the outstanding
balance of Prime-based Advances under the Revolving Credit Note
at any time. Company may prepay all or part of the outstanding
balance of Eurodollar-based Advances under the Revolving Credit
Note upon five (5) days written notice to Bank and upon payment
of a premium equal to the sum of the discounted net present
values of the interest payments that would otherwise be payable
on the principal amount (or part thereof) being prepaid, after
reducing each such interest payment by the amount of interest
that would be payable on its respective due date if such prepaid
principal (or part thereof) were re-invested at the Current
Market Rate therefor.  The discount rate for the above
computation shall be the Current Market Rate.  A certificate
shall be submitted by Bank to Company computing the prepayment
premium in the form annexed hereto as Exhibit "C" and shall be
presumed correct absent manifest error.  Any prepayment made in
accordance with this Section shall be without premium, penalty or
prejudice to Company's right to reborrow under the terms of this
Agreement.

     2.6  Company will give Bank prior notice in the form of the
Request for Advance not later than 11:00 a.m. (Detroit time) on
the date of any Prime-based Advance. Unless Bank's revolving
credit commitment shall have been suspended or terminated in
accordance with this Agreement, and subject to the terms and
conditions hereof, including but not limited to the submission of
an executed Request for a Prime-based Advance by Company without
exceptions noted to the compliance certification therein, Bank
shall make available to Company not later than 4:00 p.m. (Detroit
time) on such date the amount of such Prime-based Advance in
immediately available funds by credit to an account of Company
maintained with Bank or to such other account or third party as
Company may direct.  In the case of a Eurodollar-based Advance
each Request for Advance shall be delivered to Bank by 11:00 a.m. 
(Detroit time) three (3) Business Days prior to the proposed date
of Advance.  A Request for Advance, once delivered to Bank, shall
not be revocable by Company.  

     2.7  The Company agrees to pay to the Bank a facility fee
for the period from the date hereof to but excluding the Maturity
Date (as such date may be extended pursuant to Section 2.8
hereof) in an amount equal to 0.125% per annum of the maximum
amount of Bank's commitment (whether used or unused) in effect
from time to time hereunder.  Such facility fee shall be payable
quarterly in arrears on the first day of each calendar quarter
(in respect of the prior calendar quarter) commencing on October
1, 1996, and on the Maturity Date for any period then ending for
which such facility fee shall not have been theretofore paid. 
The facility fee shall be computed on a daily basis for the
actual number of days elapsed on the basis of a year of 360 days.

     2.8  Provided that no Event of Default has occurred and is
continuing, the Company may by written notice to the Bank (which
notice shall be irrevocable and which shall not be deemed
effective unless actually received by the Bank) on or before
February 1 of each year, beginning February 1, 1999 but not
before January 1 of each such year, request that the Bank extend
the then applicable Maturity Date to a date that is one year
later than the Maturity Date then in effect. On or before March 1
of each year in which the Company has delivered an extension
request, Bank shall have the right, in its sole and absolute
discretion, to deliver a written notice to the Company consenting
to or rejecting the requested extension. If Bank has not given
such notice to the Company by March 1 of such year, Bank shall be
deemed not to have consented to such extension. If Bank consents
to the extension request the Maturity Date shall be so extended
for an additional one year period, the term Maturity Date shall
mean such extended date and the Bank shall promptly notify the
Company in writing that such extension has occurred. If Bank
decides not to extend the Maturity Date, the Bank's commitment to
make Advances hereunder shall terminate on the Maturity Date then
in effect, and the Bank shall promptly notify Company thereof.

     2.9  The proceeds of the Revolving Credit Note are to be
applied first to repay the present indebtedness, if any, of
Company to the Bank and the Exiting Bank outstanding under the
Prior Credit Agreement (including costs under Section 2.5
thereof), upon execution of this Agreement, and then for working
capital and general corporate purposes.

     3.   CONDITIONS

     3.1  Company agrees to furnish Bank prior to the initial
borrowing under this Agreement, in form to be satisfactory to

the legal matters referred to in Sections 4.1 through 4.3 hereof;
(ii) certified copies of resolutions of the Board of Directors of
Company evidencing approval of the borrowing hereunder; (iii)

     4.   REPRESENTATIONS AND WARRANTIES

     Company represents and warrants and such representations and
warranties shall be deemed to be continuing representations and
warranties during the entire life of this Agreement:

     4.1  It is a corporation duly organized and existing in good
standing under the laws of the State of Michigan; it is duly
qualified and authorized to do business as a foreign corporation
in each jurisdiction where the character of its assets or the
nature of its activities makes such qualification necessary,
except where such failure to qualify will not have a material
adverse effect on the Company; execution, delivery and
performance of this Agreement, and any other documents and
instruments required under this Agreement, and the issuance of
the Revolving Credit Note (Revolving Credit Note herein sometimes
called "Note") by Company are within its corporate powers, have
been duly authorized, are not in contravention of law or the
terms of Company's Articles of Incorporation or Bylaws, and do
not require the consent or approval of any governmental body,
agency or authority; and this Agreement and any other documents
and instruments required under this Agreement, when issued and
delivered under this Agreement, will be valid and binding in
accordance with their terms.

     4.2  The execution, delivery and performance of this
Agreement and any other documents and instruments required under
this Agreement, and the issuance of the Note by Company, are not
in contravention of the unwaived terms of any indenture,
agreement or undertaking to which Company is a party or by which
it is bound.

     4.3  No litigation or other proceeding before any court or
administrative agency is pending, or to the knowledge of the
officers of Company is threatened against Company or any
Subsidiary, the outcome of which could materially impair
Company's consolidated financial condition or its ability to
carry on its business.

     4.4  There are no security interests in, liens, mortgages,
or other encumbrances on any of Company's or Subsidiary's assets,
except as permitted in Section 6.6 of this Agreement.

     4.5  There exists no default under the provisions of any
instrument evidencing any permitted debt or of any agreement
relating thereto, except where such default would not have a
material adverse effect on the Company and its Subsidiaries taken
as a whole.

     4.6  Company does not maintain or contribute to any employee
pension benefit plan subject to title IV of the "Employee
Retirement Income Security Act of 1974" (herein called "ERISA")
except the plans set forth in Exhibit "D" annexed hereto. (herein
called "Pension Plan").  The "unfunded past service liability" of
the Pension Plan unless unknown, as of January 1, 1995, is as set
forth in Exhibit "D" and there is no accumulated funding
deficiency within the meaning of ERISA, or any existing liability
with respect to the Pension Plan owed to the Pension Benefit
Guaranty Corporation or any successor thereto.

     4.7  The consolidated balance sheet and operating statement
of Company dated December 31, 1995, previously furnished Bank, is
substantially complete and correct and fairly presents the
consolidated financial condition of Company and the results of
its consolidated operations; since said date there has been no
material adverse change in the consolidated financial condition
of Company; to the knowledge of Company's officers, neither
Company nor its Subsidiaries has any contingent obligations
(including any liability for taxes) not disclosed by or reserved
against in said balance sheet, and at the present time there are
no unrealized or anticipated losses which would constitute an
event of default in the covenants hereunder from any present
commitment of Company or Subsidiaries.

     4.8  All tax returns and tax reports of Company and its
Subsidiaries required by law to be filed have been duly filed or
extensions obtained, and all taxes, assessments and other
governmental charges or levies (other than those presently
payable without penalty and those currently being contested in
good faith) upon Company and its Subsidiaries (or any of its or
their properties) which are due and payable have been paid. The
charges, accruals and reserves on the books of Company and its
Subsidiaries in respect of the Federal income tax for all periods
are adequate in the opinion of Company.

     4.9  Company and its Subsidiaries are, in the conduct of
their business, in compliance in all material respects with all
applicable federal, state or local laws, statutes, ordinances and
regulations, the enforcement of which, if they were not in
compliance, would have a material adverse effect on their
business or the value of their property or assets, taken as a
whole. Company and its Subsidiaries have all approvals,
authorizations, consents, licenses, orders and other permits of
all governmental agencies and authorities, whether federal, state
or local, required to permit the operation of their business as
presently conducted, except such approvals, authorizations,
consents, licenses, orders and other permits with respect to
which the failure to have can be cured without having an adverse
effect on the operation of their business taken as a whole.

     4.10 No representation or warranty by Company in this
Agreement, nor any written statement or certificate (including
financial statements) furnished or to be furnished to Bank
pursuant hereto contains or will contain any materially untrue
statement of any fact or omits or will omit to state a fact
necessary to make such representation, warranty, statement or
certificate not misleading.

     4.11 Except as disclosed on Exhibit "E" hereto, neither
Company nor any Subsidiary is a party to any litigation or
administrative proceeding, nor so far as is known by Company is
any litigation or administrative proceeding threatened against
Company or any Subsidiary, which in either case (A) asserts or
alleges that Company or any Subsidiary violated Environmental
Laws (as defined herein) (B) asserts or alleges that Company or
any Subsidiary is required to clean up, remove, or take remedial
or other response action due to the disposal, depositing,
discharge, leaking or other release of any hazardous substances
or materials, (C) asserts or alleges that Company or any
Subsidiary is required to pay all or a portion of the cost of any
past, present, or future cleanup, removal or remedial or other
response action which arises out of or is related to the
disposal, depositing, discharge, leaking or other release of any
hazardous substances or materials by Company or any Subsidiary,
except for such matters which, individually or in the aggregate,
would not have a material adverse effect on the financial
condition or business of the Company and its Subsidiaries, taken
as a whole.

     4.12 To the best knowledge of Company, there are no
conditions existing as of the date hereof which (A) would subject
Company or any Subsidiary to damages, penalties, injunction
relief or cleanup costs under any applicable Environmental Laws
or which require or are likely to require cleanup, removal,
remedial action or other response pursuant to applicable
Environmental Laws by Company or any Subsidiary and (B) would,
individually or in the aggregate, have a material adverse effect
upon the Company and its Subsidiaries, taken as a whole.

     4.13 Except as disclosed on Exhibit E hereto, neither
Company nor any Subsidiary is subject to any judgment, decree,
order or citation related to or arising out of applicable
Environmental Laws and to the best knowledge of the Company,
neither Company nor any Subsidiary has been named or listed as a
potentially responsible party by any governmental body or agency
in a matter arising under any applicable Environmental Laws,
except for such matters which, individually or in the aggregate,
would not have a material adverse effect on the financial
condition or business of the Company and its Subsidiaries, taken
as a whole.

applicable Environmental Laws or which seeks damages or civil,
criminal or punitive penalties from Company or any Subsidiary for

its Subsidiaries, taken as a whole.

as Company becomes aware of any condition or circumstance which
makes the environmental warranties contained in this Agreement
incomplete or inaccurate in any material respect as of any date.

investigation, environmental audit(s), and legal expenses)
arising out of any claim, loss or damage under any applicable
Environmental Laws, caused by or in any way related to any
property owned or operated by Company or any Subsidiary;
provided, however, that the foregoing indemnification shall not
be applicable when arising from events or conditions occurring
while Bank is in sole possession (subject to the rights of any
creditors of Company) of the property. In no event shall Company
be liable hereunder for any loss, damages, suits, penalties,
costs, liabilities or expenses arising from any act of gross

     10.  MISCELLANEOUS

     10.1 This Agreement shall be binding upon and shall inure to
the benefit of Company and Bank and their respective successors
and assigns, except that the credit provided for under this
Agreement and no part thereof and no obligation of Bank hereunder
shall be assignable or otherwise transferable by Company.

     10.2 Company, upon thirty (30) days' prior notice to the
Bank, may from time to time permanently reduce the credit
provided for under this Agreement by ONE MILLION DOLLARS
($1,000,000.00) in aggregate or any larger integral multiple
thereof in aggregate. Any such reduction shall reduce the
commitment of the Bank to lend under Section 2.1, and on the date
of reduction, reduce the amount of the revolving credit, subject
to payment (to the date of such reduction) of the facility fee
under Section 2.7.

     10.3 If with respect to any Interest Period Bank determines
that, by reason of circumstances affecting the foreign exchange
and interbank markets generally, deposits in Eurodollars in the
applicable amounts are not being offered to Bank for such
Interest Period, then Bank shall forthwith give notice thereof to
the Company.  Thereafter until Bank notifies Company that such
circumstances no longer exist, the obligation of Bank to make
Eurodollar-based Advances shall be suspended.

     10.4 If, after the date hereof, the introduction of, or any
change in, any applicable law, rule or regulation or in the
interpretation or administration thereof by any governmental
authority charged with the interpretation or administration
thereof, or compliance by Bank (or its Eurodollar Lending Office)
with any request or directive (whether or not having the force of
law) of any such authority, shall make it unlawful or impossible
for the Bank (or its Eurodollar Lending Office) to honor its
obligations hereunder to make or maintain any advance or the
indebtedness under any Note with interest at the Eurodollar-based
Rate, Bank shall forthwith give notice thereof to Company. 
Thereafter the obligation of Bank to make or maintain Eurodollar-
based Advances shall be suspended and thereafter Company may
select as Applicable Interest Rates only those which remain
available.

     10.5 If the adoption after the date hereof, or any change
after the date hereof in, any applicable law, rule or regulation
of any governmental authority, central bank or comparable agency
charged with the interpretation or administration thereof, or
compliance by Bank (or their Eurodollar Lending Office) with any
request or directive (whether or not having the force of law)
made by any such authority, central bank or comparable agency
after the date hereof (a "Change in Law"):

     (a)  shall subject Bank (or its Eurodollar Lending Office)
          to any tax, duty or other charge with respect to any
          advance or the Note or shall change the basis of
          taxation of payments to Bank (or its Eurodollar Lending
          Office) of the principal of or interest on any advance
          or the Note (except for changes in the rate of tax on
          the overall net income of Bank or its Eurodollar
          Lending Office imposed by the jurisdiction in which
          said Bank's principal executive office or Eurodollar
          Lending Office is located); or

     (b)  shall impose, modify or deem applicable any reserve
          (including, without limitation, any imposed by the
          Board of Governors of the Federal Reserve System)
          special deposit or similar requirement against assets
          of, deposits with or for the account of, or credit
          extended by Bank (or its Eurodollar Lending Office) or
          shall impose on Bank (or its Eurodollar Lending Office)
          or the foreign exchange and interbank markets any other
          condition affecting any advance or the Note;

and the result of any of the foregoing is to increase the cost to
Bank of maintaining any part of the indebtedness hereunder or to
reduce the amount of any sum received or receivable by Bank under
the Note, by an amount deemed by Bank to be material, then Bank
shall promptly notify Company of such fact and demand
compensation therefor and, within fifteen days after demand by
Bank, Company agrees to pay to Bank such additional amount or
amounts as will compensate Bank for such increased cost or
reduction. Bank will promptly notify Company of any event of
which it has knowledge which will entitle Bank to compensation
pursuant to this Section.  A certificate of Bank setting forth
the basis for determining such additional amount or amounts
necessary to compensate Bank shall be conclusively presumed to be
correct save for manifest error.  Any further Eurodollar-based
Rate shall be automatically adjusted to compensate Bank for such
changes set forth above.

     10.6 In the event that at any time after the date of this
Agreement any Change in Law shall, in the opinion of Bank,
require that the commitment of the Bank under this Agreement be
treated as an asset or otherwise be included for purposes of
calculating the appropriate amount of capital to be maintained by
the Bank or any corporation controlling the Bank (the "Parent
Corporation"), Bank shall notify Company. Company and Bank shall
thereafter negotiate in good faith an agreement to increase the
facility fee payable to Bank under this Agreement, which in the
opinion of Bank, will adequately compensate Bank for the costs
associated with such Change of Law. If such increase is approved
in writing by Company within thirty (30) days from the date of
the notice to Company from Bank, the facility fee payable by
Company under this Agreement shall, effective from the date of
such agreement, include the amount of such agreed increase.  If
Company and Bank are unable to agree on such an increase within
thirty (30) days from the date of the notice to Company, Company
shall have the option, exercised by written notice to Bank within
forty-five (45) days from the date of the aforesaid notice to
Company from Bank, to terminate the commitment of Bank hereunder. 
If (a) Company and Bank fail to agree on an increase in the
facility fee, or (b) Company fails to give timely notice that it
has elected to exercise its option to terminate the commitment as
set forth above, then the commitment shall automatically
terminate as of the last day of the aforesaid forty-five (45) day
period.

     10.7 No delay or failure of Bank in exercising any right,
power or privilege hereunder shall affect such right, power or
privilege, nor shall any single or partial exercise thereof
preclude any further exercise thereof, or the exercise of any
other power, right or privilege.  The rights of Bank under this
Agreement are cumulative and not exclusive of any right or
remedies which Bank would otherwise have.

     10.8 If there is an event of default, Company shall pay all
out-of-pocket expenses incurred by the Bank (including fees and
disbursements of staff or outside counsel) in connection with
such event of default.  Company shall indemnify Bank against any
transfer taxes, documentary taxes, assessments or charges made by
any governmental authority by reason of the execution and
delivery of this Agreement or the Note.

     10.9 All notices with respect to this Agreement shall be
deemed to be completed (unless otherwise stated) upon mailing by
certified mail to the following:

action to be taken by any Person which such Person is prohibited
from taking, such provision shall be applicable whether such
action is taken directly or indirectly by such Person, whether or
not expressly specified in such provision.

     10.11  Each covenant hereunder shall be given independent
effect (subject to any exceptions stated in such covenant) so
that if a particular action or condition is not permitted by any
such covenant (taking into account any such stated exception),
the fact that it would be permitted by any exception to, or would
be otherwise within the limitations of, another covenant shall
not avoid the occurrence of an Event of Default.

     10.12  This Agreement and the Note shall be governed by, and
construed and enforced in accordance with, Michigan law.

     10.13 This Agreement shall become effective upon the
execution hereof by Bank and Company.  This Agreement may be

Rate; provided, however, that interest shall be payable at the
Prime-based Rate in the event and so long as Company shall not
have elected another Applicable Interest Rate.  Interest shall be
payable quarterly commencing on September 30, 1996, on the unpaid
balance of the Prime-based Advances from time to time
outstanding, and on the last day of each calendar quarter
thereafter.  Interest on each Eurodollar-based Advance shall be
payable on the last day of the Interest Period applicable thereto
and if such Interest Period is longer than three months, interest
shall be payable at intervals of three months from the first day
thereof.  In the event and so long as Company shall be in default
under a Eurodollar-based Advance, interest shall be payable at
the greater of (i) 2% over the Eurodollar-based Rate applicable
thereto, or (ii) 2% over the Prime-based Rate, until the
Eurodollar-Interest Period applicable thereto shall expire, and
thereafter the interest shall be payable at the rate of 2% over
the Prime-based Rate.  In the event and so long as Company shall
be in default under a Prime-based Advance, interest shall be
payable at 2% over the Prime-based Rate.
