otherwise defined herein.

      B.  The Borrower has requested that the Lenders (i) waive certain
existing defaults, (ii) make $1,000,000 available to the Borrower for
Revolving Loans and Letters of Credit (but such Letters of Credit shall not

$3,375,000 after giving effect to this Amendment, and (iii) make certain
other amendments to the Credit Agreement, and the Lenders are willing to so
waive and so amend the Credit Agreement, all in the manner and on the terms

       NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto agree as

SECTION 1.  WAIVER.

       The Borrower has disclosed to the Lenders that it was in default of

(Fixed Charge Coverage Ratio) of the Credit Agreement as of June 2, 2007,
August 31, 2007 and November 30, 2007 (collectively, the "Existing
Defaults").  The Borrower hereby requests that the Lenders waive the
Existing Defaults, and, subject to the satisfaction of the conditions
precedent set forth in Section 3 below, the Lenders hereby waive the
Existing Defaults.  The waivers set forth herein shall not extend to any
matters or time periods other than as set forth above.

SECTION 2.  AMENDMENTS.

       Subject to the satisfaction of the conditions precedent set forth in
Section 3 below, the Credit Agreement shall be and hereby is amended as
follows:

2.1.  Section 1.8(a) of the Credit Agreement shall be amended and restated
in its entirety to read as follows:


      Section 1.8.  Maturity of Loans.
      (a)  Scheduled Payments of Term Loans.  The Borrower shall make
           principal payments on the Term Loans in installments on the last
           day of each March, June, September, and December in each year,
           with the amount of each such principal installment to equal the
           amount set forth in Column B below shown opposite of the relevant
           due date as set forth in Column A below:

                  COLUMN A                 COLUMN B

                                     SCHEDULED PRINCIPAL
                PAYMENT DATE        PAYMENT ON TERM LOANS

                   03/31/08                $750,000
                   06/30/08                $750,000
                   09/30/08                $750,000
                   12/31/08                $750,000
                   03/31/09              $1,250,000

           , it being agreed that the final payment of both principal and
           interest not previously paid on the Term Loans shall be due and
           payable on June 30, 2009 (the "Term Loan Maturity Date").  Each
           such principal payment shall be applied to the Lenders holding
           the Term Loans pro rata based upon their Term Loan Percentages.

2.2.  Section 1.9 (Prepayments) of the Credit Agreement shall be amended and
restated in its entirety to read as follows:

      (c)  Any amount of Revolving Loans paid or prepaid before the
           Revolving Credit Termination Date may, subject to the terms and
           conditions of this Agreement, be borrowed, repaid and borrowed
           again.  No amount of the Term Loans paid or prepaid may be
           reborrowed, and, in the case of any partial prepayment, such
           prepayment shall be applied to the remaining amortization
           payments on the Term Loans in inverse order of maturity; provided
           however, that the mandatory prepayments made by virtue of the
           first three payments received on account of the MIR3, Inc. note
           shall be applied to the principal installment due March 31, 2008.
           For further clarity, all subsequent payments on the MIR3, Inc.
           note shall be applied to the remaining amortization payments on
           the Term Loan in inverse order of maturity.

2.3. Section 2.1 of the Credit Agreement shall be amended by adding new
subsections (d), (e) and (f) to read as follows:

      (d)  Exit Fee.  The Borrower shall pay to the Administrative Agent for
           the ratable account of the Lenders in accordance with their
           respective Percentages an exit fee of $500,000 which shall be
           fully earned on the Fourth Amendment Effective Date and shall be
           due and payable on the Revolving Credit Termination Date;
           provided, however, (i) if the Obligations are paid in full on or
           before December 31, 2008, such fee shall be forgiven, and (ii) if
           the Borrower receives at least $5,000,000 of new cash equity or
           cash proceeds of Subordinated Debt on or before December 31,
           2008, then such fee shall be reduced to $300,000.

      (e)  Default Interest Prior to Fourth Amendment Effective Date.  The
           amount of interest accrued by virtue of the imposition of the
           default rate of interest pursuant to Section 1.10 hereof through
           the Fourth Amendment Effective Date was $204,086 (the "Default
           Interest Amount").  The Borrower acknowledges and agrees that the
           Default Interest Amount is justly and truly owing by the Borrower
           without defense, offset or counterclaim and is due and payable on
           the Revolving Credit Termination Date; provided, however (i) if
           the Obligations are paid in full on or before December 31, 2008,
           the Default Interest Amount shall be forgiven, and (ii) if the
           Borrower receives at least $5,000,000 of new cash equity or cash
           proceeds of Subordinated Debt on or before December 31, 2008,
           then the Default Interest Amount shall be reduced to by 40%.

      (f)  Audit Fees.  The Borrower shall pay to the Administrative Agent
           for its own use and benefit charges for audits of the Collateral
           performed by the Administrative Agent or its agents or
           representatives in such amounts as the Administrative Agent may
           from time to time request (the Administrative Agent acknowledging
           and agreeing that such charges shall be computed in the same
           manner as it at the time customarily uses for the assessment of
           charges for similar collateral audits); provided, however, that
           in the absence of any Default and Event of Default, the Borrower
           shall not be required to pay the Administrative Agent for more
           than two (2) such audits per calendar year.
