                                 LOAN AGREEMENT



     THIS LOAN AGREEMENT,  made this _____ day of February,  2002 by and between
Tecstar,  LLC, an Indiana limited liability company, of Goshen,  Indiana (herein
called  "Company"),  and  COMERICA  BANK,  a Michigan  banking  corporation,  of
Detroit, Michigan (herein called "Bank");

     WITNESSETH:

     1. THE INDEBTEDNESS: Line of Credit

     1.1 Subject to the terms of this Agreement,  Bank agrees to lend to Company
at any time and from time to time from the effective  date hereof until April 1,
2004  sums  not  to  exceed  under  the  line  of  credit  Ten  Million  Dollars
($10,000,000) in aggregate principal amount at any one time outstanding. Company
shall  execute and deliver to Bank a Line of Credit Note  (herein  called  "Line
Note") in form  similar  to that  annexed  hereto  as  Exhibit  "A" to  evidence
advances, repayments and readvances made from time to time, subject to the terms
and conditions of this Agreement.

     1.2 The Line Note shall mature on April 1, 2004,  and the balance from time
to time outstanding  shall bear interest at a per annum rate equal to the Bank's
Prime  Rate  plus or minus,  as  applicable,  the  Applicable  Margin.  Upon the
occurrence  of any event of  default  hereunder,  interest  shall  accrue on the
unpaid  principal  balance at the per annum rate of three percent (3%) above the
rate otherwise in effect.  Interest shall be payable monthly commencing on March
1, 2002 and on the first business day of each month  thereafter.  Interest shall
be computed on a daily basis using a year of 360 days,  assessed  for the actual
number of days  elapsed,  and in such  computation  effect shall be given to any
change in the  interest  rate  resulting  from a change in the Prime Rate on the
date of such  change in the Prime  Rate.  "Prime  Rate"  shall  mean the rate of
interest  established  by Bank and publicly  announced as its prime rate for its
borrowers  as the  same  may be  changed  from  time  to  time,  which  may  not
necessarily be Bank's lowest rate for loans.

     A late  installment  charge  equal  to  five  percent  (5%)  of  each  late
installment  may be charged on any  installment  payment  not  received  by Bank
within ten (10) calendar days after the  installment  due date but acceptance of
this  charge  shall  not  waive  any  default  or event of  default  under  this
Agreement.

     "Applicable  Margin"  shall  mean  as of any  date  of  determination,  the
applicable  interest rate margin determined in accordance with the provisions of
Section  1.A by  reference  to the  appropriate  columns in the  pricing  matrix
attached to this Agreement as Schedule 1.



<PAGE>


     1.3 Bank shall not make any  advances  under the Line Note  unless  Company
shall  have  first  filed  with  Bank a  Request  for  Draw and  Certificate  of
Compliance  (as of the date of the  borrowing)  in form  similar to that annexed
hereto as Exhibit "B", executed by an authorized  officer of Company.  Bank may,
at its  option,  lend  under  the Line  Note upon the  telephone  request  of an
authorized  officer  or agent of Company  and,  in the event Bank makes any such
advance upon a telephone request,  the requesting officer shall mail to Bank, on
the same day as such telephone  request,  a Request for Draw and  Certificate of
Compliance in the form attached as Exhibit "B".  Company hereby  authorizes Bank
to disburse advances under the Line Note pursuant to the telephone  instructions
of any person  purporting  to be an  authorized  officer of Company  and Company
shall bear all risk of loss resulting from disbursements made upon any telephone
request.  Each time Company requests an advance under the Line Note by telephone
it shall be deemed to have  represented  that no  condition  exists or event has
occurred which  constitutes or, with the giving of notice or the passage of time
would constitute, a default under this Agreement.

     1.4 The aggregate  principal amount at any one time  outstanding  under the
Line Note and the  outstanding  amount of all Letters of Credit  (together  with
unreimbursed  drawings  thereunder)  shall never exceed the formula set forth in
the  Advance  Formula  Agreement  dated as of the date  hereof or in any Advance
Formula Agreement delivered by Company to Bank in substitution therefor. Company
shall immediately make all payments necessary to comply with this provision.

     1.5  Company  shall pay to Bank an unused  fee equal to one  quarter of one
percent  (1/4%) per annum  multiplied  by the average  daily amount by which Ten
Million  Dollars  ($10,000,000)  exceeds  the  aggregate  amount of  outstanding
advances  under the Line Note.  The unused  fee shall be  payable  quarterly  in
arrears on the first day of each calendar quarter  (commencing on April 1, 2002)
and on the maturity  date of the Line Note.  Such fee shall be calculated in the
same manner as interest is calculated hereunder.

     1.6 In addition  to advances  under the Line Note to be provided to Company
by Bank under and pursuant to Section 1.1 of this Agreement,  Bank may issue, or
commit to issue, from time to time, standby letters of credit for the account of
Company  (herein  individually  called a "Letter  of  Credit"  and  collectively
"Letters of Credit") in  aggregate  undrawn  amounts not to exceed Five  Hundred
Thousand Dollars ($500,000) at any one time outstanding;  provided, however that
the sum of the aggregate amount of advances outstanding under the Line Note plus
the  undrawn  amounts  of all  Letters of Credit  shall not  exceed Ten  Million
Dollars ($10,000,000.00) at any one time; and provided further that no Letter of
Credit shall,  by its terms,  have an expiration  date which extends  beyond the
maturity date of the Line Note. In addition to the terms and  conditions of this
Agreement,  the  issuance of any Letters of Credit  shall also be subject to the
terms  and  conditions  of any  letter  of credit  applications  and  agreements
executed and delivered by Company unto Bank with respect thereto. The commission
rate  and  payment  of the  commission  for  each  Letter  of  Credit  shall  be
established by Bank at the time of issuance of each Letter of Credit.

     1.7 Company may prepay the Line Note in whole or in part without premium or
penalty.

     1.8  Advances  under the Line Note shall be used for  working  capital  and
other general corporate purposes.

day of the first month  following the required date of delivery of the financial
statements under Section 4.1 hereunder, in each case establishing  applicability
of the appropriate  adjustment.  From the effective date until the required date
of delivery  under Section 4.1 of the  Company's  financial  statements  for the

$10,000,000                                                    Detroit, Michigan
                                                            ______________, 2002


     On or before April 1, 2004, FOR VALUE RECEIVED,  the undersigned,  Tecstar,
LLC, an Indiana limited liability company (herein called "Company")  promises to

"Bank")  at its Main  Office at 500  Woodward  Avenue,  Detroit,  Michigan,  the
indebtedness or so much of the sum of Ten Million Dollars  ($10,000,000)  as may
from time to time have been advanced and then be outstanding hereunder and under
a certain Loan Agreement by and between Company and Bank dated  _______________,
2002 (herein called "Loan Agreement").

     The indebtedness  outstanding  under this Note from time to time shall bear
interest  at a per annum rate equal to the Bank's  Prime Rate plus or minus,  as
applicable,  the Applicable Margin (as defined in the Loan Agreement).  Upon the
occurrence  of any  event of  default  hereunder  or under  the Loan  Agreement,
interest shall accrue on the unpaid balance  hereunder at a per annum rate equal
to three  percent  (3%) above the rate  otherwise in effect.  Interest  shall be
payable monthly on the unpaid  principal  balance from time to time  outstanding
commencing on  ___________  1, 2002 and on the first  business day of each month
thereafter  until April 1, 2004 when the entire unpaid  balance of principal and
interest  shall be due and payable.  Interest shall be computed on a daily basis
using a year of 360 days for the actual  number of days  elapsed,  and,  in such
computation,  effect shall be given to any change in the interest rate resulting
from a change in the Prime  Rate on the date of such  change in the Prime  Rate.
"Prime  Rate" shall mean the rate of interest  established  by Bank and publicly
announced as its prime rate as the same may be changed from time to time,  which
may not necessarily be Bank's lowest rate for loans. This Note may be prepaid at
any time without premium or penalty.

     This Note evidences borrowing under, is subject to, is secured pursuant to,
shall be prepaid in accordance  with,  and may be matured under the terms of the
Loan Agreement,  to which reference is hereby made. As additional security, Bank
is granted a lien on all personal  property and assets  (including  deposits and
other  credits) of Company at any time in possession or control of (or owing by)
Bank for any purpose.

     All  agreements  between  Company and Bank  pertaining to the  indebtedness
described herein are expressly  limited so that in no event whatsoever shall the
amount of interest  paid or agreed to be paid to Bank exceed the highest rate of
interest   permissible   under  applicable  law.  If,  from  any   circumstances
whatsoever, fulfillment of any provision of the Loan Agreement, this Note or any
other  instrument  securing  this  Note or all or any  part of the  indebtedness
secured  thereby,  at the time performance of such provision shall be due, shall
involve  exceeding  the interest  limitation  validly  prescribed by law which a
court of competent jurisdiction may deem applicable hereto, then, the obligation
to be  fulfilled  shall be reduced to an amount  computed at the highest rate of
interest  permissible  under  such  applicable  law,  and  if,  for  any  reason
whatsoever,  Bank shall ever receive as interest an amount which would be deemed
unlawful under such applicable law, such interest shall be automatically applied
to the payment of the principal  amount  described  herein or otherwise  owed by
Company to Bank, (whether or not then due and payable) and not to the payment of
interest.

     Company hereby waives presentment for payment,  demand,  protest and notice
of dishonor and nonpayment of this Note and agrees that no obligation  hereunder
shall  be  discharged  by  reason  of any  extension,  indulgence,  release,  or
forbearance  granted  by any  holder of this Note to any party now or  hereafter
liable  hereon or any  present  or  subsequent  owner of any  property,  real or
personal,  which is now or hereafter security for this Note. Any transferees of,
or endorser,  guarantor or surety  paying this Note in full shall succeed to all
rights  of Bank,  and Bank  shall be  under no  further  responsibility  for the
exercise  thereof or the loan evidenced  hereby.  Nothing herein shall limit any
right granted Bank by other instrument or by law.

     If the interest and principal  hereof are not fully paid at maturity hereof
(whether by acceleration or otherwise),  Company shall pay the holder hereof all
its reasonable costs of collection of said principal and interest including, but
not limited to, reasonable attorney fees.

     THE UNDERSIGNED AND THE 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,  WAIVES ANY RIGHT TO
TRIAL  BY  JURY  IN  THE  EVENT  OF  LITIGATION  REGARDING  THE  PERFORMANCE  OR
ENFORCEMENT OF, OR IN ANY WAY RELATED TO THIS NOTE.

     Notwithstanding  anything  herein to the contrary,  nothing shall limit any
rights granted Bank by other instruments or by law.
