as amended by Amendment to Promissory Note (Term Loan) dated June 1, 2004, (ii)

              1.

            	
              Amendments to the Loan
      Agreement.

            


    

     

    A.         Section 1 (Definitions) is
amended to add the following definition:

     

    “Capital Expenditures” means
all expenditures which, in accordance with  generally accepted
accounting principles, would be required to be capitalized and shown on the
balance sheet of Borrower, including expenditures in respect of capital leases,
but excluding expenditures made in connection with the replacement, substitution
or restoration of assets to the extent financed (a) from insurance proceeds (or
other similar recoveries) paid on account of the loss of or damage to the assets
being replaced or restored or (b) with awards of compensation arising from the
taking by eminent domain or condemnation of the assets being
replaced.

     

    B.          Section 7 (Borrower’s Affirmative
Covenants).  Section 7 (Borrower’s Affirmative Covenants) of
the Loan Agreement is hereby amended by deleting the existing subsection (d) and
replacing it with the following subsection (d):

     

    d.           Liens.  Borrower
will cause any lien (including, without limitation, any judgment, attachment,
execution, mechanic’s lien, or federal or state income tax lien) that may attach
to Borrower’s real estate or personal property to be satisfied and released no
later than thirty (30) days after attachment, except for (i) the lien of current
property taxes and assessments, (ii) liens contested in good faith in an
appropriate proceeding if Borrower has given Lender any assurances Lender deems
necessary under the circumstances, (iii) liens in favor of Lender, (iv) any lien
in favor of Entrepreneur Growth Capital, LLC, or its successor as provider of an
asset-based line of credit, (the “Asset Based Lender”) to secure indebtedness
not to exceed the principal amount of $3,000,000.00, provided that any real
property lien is governed by an Intercreditor Agreement by and between Lender
and the Asset Based Lender, and (v) those liens permitted pursuant to Section
9(e) herein.

     

    C.          Section 8 (Borrower’s Financial
Covenants).  Section 8 (Borrower’s Financial Covenants) of the
Loan Agreement is hereby amended by deleting the existing subsections (b) and

    b.       Fixed Charge Coverage
Ratio.  Borrower will maintain a Fixed Charge Coverage Ratio of
not less than 1.25 to 1.00.  “Fixed Charge Coverage Ratio” means the
ratio of (i) the sum of Borrower’s aggregate net income for the current fiscal
year as of the end of such period, plus depreciation expense and other non cash
expenditures, plus interest expense, plus income tax expense, less Capital
Expenditures not funded with long term debt, less income tax paid or accrued in
the current fiscal year as of the end of such period, to (ii) the sum of all
interest payments and the principal payments on long-term debt paid or accrued
in the current fiscal year as of the end of such period, including payments made
under capitalized leases but excluding the anticipated principal reductions of
the Replacement Note and the Mt. Vernon Note on or before December 18, 2010 and
February 11, 2011, respectively.  The Fixed Charge Coverage Ratio will
be tested on a fiscal year-to-date basis at the end of each fiscal quarter
beginning December 31, 2010.

    c.           Borrower
will maintain a Total Liabilities to Tangible Net Worth Ratio of not less than
2.10 to 1.00, tested quarterly at the end of each fiscal quarter beginning
December 31, 2010.

     

    C.          Section 9 (Negative
Covenants).  Section 9 (Negative Covenants) of the Loan
Agreement is hereby amended by deleting the existing subsections (d) and (e) and
replacing them with the following subsections (d) and (e):

     

    d.           Borrowing.  Borrower
will not, without Lender’s prior written consent, create, incur, assume or
suffer to exist any indebtedness except (a) trade accounts and normal business
accruals payable in the ordinary course of business, (b) Indebtedness to Lender,
(c) an asset-based line of credit available to Borrower from the Asset Based
Lender in the maximum principal amount not to exceed $3,000,000.00, (d)
indebtedness for Capital Expenditures, and (e) any other unsecured indebtedness,
nor shall Borrower assume, guarantee or otherwise become liable as a guarantor
or surety for the obligations of any person or firm except guaranties in favor
of Lender.

     

    e.           Liens and
Encumbrances.  Borrower will not, without Lender’s prior
written consent, create or permit to exist any mortgage, pledge, lien, security
interest or other encumbrance (except those in favor of Lender, except those in
favor of Asset Based Lender as permitted in Section 7.d. herein, and except
those encumbering the specific asset hereafter acquired in connection with any
Capital Expenditures) in any of Borrower’s tangible or intangible real or
personal property, whether now owned or hereafter acquired, nor will Borrower
become security on a recognizance or other bond.

     

    2.           Continuing
Effect.  All other terms, conditions, representations,
warranties and covenants contained in the Loan Agreement shall remain the same
and shall continue in full force and effect.  In consideration hereof,
Borrower represents and warrants that each representation and warranty set forth
in the Loan Agreement, as hereby amended, remains true and correct as of the
date hereof, except to the extent that such representation and warranty is
expressly intended to apply solely to an earlier date, that there presently
exist no known offsets, counterclaims or defenses to the performance of the
obligations under the Instruments (collectively, the “Obligations”) (such known
offsets, counterclaims or defenses, if any, being hereby expressly waived), and
that Borrower has no other known claims, demands, allegations or rights of
action of any nature based on any matter arising from or related to the
Obligations or Borrower’s relationship with the Lender (such known claims,
demands, allegations or rights of action, if any, being hereby expressly waived)
nor has there occurred any Event of Default under the Loan Agreement or any of
the Instruments, and that there will be no Event of Default after giving effect
to the transactions contemplated by this Amendment.  The
representations and warranties contained in the Loan Agreement originally shall
survive this Amendment in their original form and shall survive as continuing
representations and warranties of Borrower.  Except as expressly
herein provided, the Loan Agreement and this Amendment shall be interpreted,
wherever possible, in a manner consistent with one another, but in the event of
any irreconcilable inconsistency, this Amendment shall control.  The
parties each hereby agree to cooperate in all reasonable requests of each other
party hereto, including, without limitation, the authentication of financing
statements and other documents, which the requesting party deems reasonable,
necessary, appropriate or expedient to carry out the intents and purposes of
this Amendment.  Capitalized terms used herein and not specifically
herein defined shall have the meanings ascribed in the Loan
Agreement.

Agreement should replace the Prior Loan Agreement and, in good faith, Lender has

Prior Notes, (iii) the Prior Mortgages, (iv) a certain First Replacement

with the office of the Recorder of Posey County, Indiana, and all documents and
instruments executed in connection therewith, shall be monitored and
administered in accordance with the Loan Agreement, and in the event of any
irreconcilable inconsistency between the Prior Loan Agreement and the Loan
Agreement, the Loan Agreement shall control.

     

    3.           Conditions
