      preceding the applicable Adjustment Date (as defined below)(except that, for

                Charges

            	
              Interest
                Rate

            
	
              Less
                than 1.0 to 1.0

            	
              Two
                and three-quarters percent (2.75%) per annum in excess of the Prime
                Rate

    ;
      provided that
      (i) the
      Interest Rate shall thereafter be subject to reduction or increase, as
      applicable and as set forth in the table above, on a quarterly basis according
      to the performance of Borrower as measured by the ratio of EBITDA to Fixed
      Charges as of the last day of the
      fiscal quarter immediately preceding the applicable Adjustment Date, for the
      period of four (4) fiscal quarters ended on the last day of the fiscal quarter
      immediately preceding the applicable Adjustment Date (except
      that, for the fiscal quarters ending on September 30, 2008, and December 31,
      2008, the Borrower's ratio of EBITDA to Fixed Charges for purposes of this
      definition shall be calculated for the periods beginning on February 1, 2008,
      and ending on the applicable date); (ii)
      except
      as set forth in clause (iii) below, any increase or reduction in the Interest
      Rate provided for in this subsection (C) shall be effective on the first day
      of
      the month immediately following Lender's receipt and review of the applicable
      financial statements and corresponding compliance certificate (each, an
      "Adjustment Date"); (iii) if the financial statements and the corresponding
      compliance certificate of Borrower setting forth the ratio of EBITDA to Fixed
      Charges are not received by Lender on or prior to the date required pursuant
      to
      Section 9.6(a) of this Agreement, the Interest Rate shall be determined as
      if
      the ratio of EBITDA to Fixed Charges is less than 1.0 to 1.0 (without regard
      to
      the actual ratio of EBITDA to Fixed Charges) until such time as such financial
      statements and compliance certificate are received by Lender and any Event
      of
      Default resulting from Borrower's failure to timely deliver such financial
      statements or compliance certificate is waived in writing by Lender; (iv) Lender
      shall be entitled to accrue and receive interest at the Default Rate as defined
      in, and to the extent authorized by, subsection (D) below, and, on each date
      that the Default Rate accrues on any Loans, the Interest Rate on such date
      for
      such Loans shall be determined as if the ratio of EBITDA to Fixed Charges is
      less than 1.0 to 1.0 (without regard to the actual ratio of EBITDA to Fixed
      Charges); (v) for the final fiscal quarter of any fiscal year, Borrower may
      provide the monthly unaudited financial statements of Borrower required under
      Section 9.6(a) of this Agreement for the purpose of determining the Interest
      Rate; however,
      if,
      upon delivery of the annual audited financial statements required to be
      submitted by Borrower to Lender pursuant to Section 9.6(a) of this Agreement,
      Borrower has not met the criteria for reduction of the Interest Rate pursuant
      to
      the terms hereinabove for the final fiscal quarter of the fiscal year then
      ended, then (x) such Interest Rate reduction shall be terminated and, effective
      on the first day of the month immediately following the month in which Lender
      receives and reviews such audited financial statements, the Interest Rate shall
      be the Interest Rate that would have been in effect if such reduction had not
      been implemented based upon the monthly unaudited financial statements of
      Borrower for the final fiscal quarter of the fiscal year then ended, and (x)
      Borrower shall pay to Lender, on demand, the amount equal to the difference
      between the amount of interest and fees that would have been paid using the
      Interest Rate determined based upon such audited financial statements and the
      amount of interest and fees actually paid during the period in which the
      reduction of the Interest Rate was in effect based upon the monthly unaudited
      financial statements for the final fiscal quarter of the fiscal year then ended;
      and

    (D) notwithstanding
      anything to the contrary contained herein, at Lender's option and without
      notice, the rate of interest (the "Default Rate") equal to three percent (3.00%)
      per annum in excess of rate of interest set forth in subsection (A), (B) or
      (C)
      above, as applicable, (i) during the period from and after the date of
      termination or non-renewal of this Agreement until such time as all Obligations
      are indefeasibly paid and satisfied in full in immediately available funds;
      (ii)
      during the period from and after the date of the occurrence of any Event of
      Default, and for so long as such Event of Default is continuing as determined
      by
      Lender; and (b) on the Revolving Loans at any time outstanding in excess of
      the
      Borrowing Base or the Revolving Loan Limit (whether or not such excess(es)
      arise
      or are made with or without Lender's knowledge or consent and whether made
      before or after an Event of Default).

     

    (b) By
      adding
      to Section
      1
      of the
      Loan Agreement, in proper alphabetical sequence, the following new
      definition:

    3. Borrower
      hereby ratifies and reaffirms the Obligations, each of the Financing Agreements
      and all of Borrower's covenants, duties, indebtedness and liabilities under
      the
      Financing Agreements.

    

    4. To
      induce
      Lender to enter into this Amendment and to grant the accommodations set forth
      herein, Borrower hereby acknowledges and stipulates that the Loan Agreement
      and
      the other Financing Agreements executed by Borrower are legal, valid and binding
      obligations of Borrower that are enforceable against Borrower in accordance
      with
      the terms thereof; all of the Obligations are owing and payable without defense,
      offset or counterclaim (and to the extent there exists any such defense, offset
      or counterclaim on the date hereof, the same is hereby waived by Borrower);
      and
      the security interests and liens granted by Borrower in favor of Lender are
      duly
      perfected, first priority security interests and liens.

    

    5. To
      induce
      Lender to enter into this Amendment and to grant the accommodations set forth

      Event of Default exists on the date hereof; the execution, delivery and
      performance of this Amendment have been duly authorized by all requisite
      corporate action on the part of Borrower and this Amendment has been duly
      executed and delivered by Borrower; and except as may have been disclosed in
      writing by Borrower to Lender prior to the date hereof, all
      of
      the representations and warranties made by Borrower in the Loan Agreement are
      true and correct on and as of the date hereof.

    

    6. In
      consideration of Lender's willingness to enter into this Amendment and to grant
      the accommodations set forth herein, Borrower hereby agrees to pay to Lender
      (i)
      a nonrefundable amendment fee (the "Amendment Fee") in the amount of twenty-five
      thousand dollars ($25,000) in immediately available funds on the date hereof,
      which shall be fully earned on the date hereof, and (ii) on
      demand,
      all
      costs and expenses incurred by Lender in connection with the preparation,
      negotiation and execution of this Amendment and any other Financing Documents
      executed pursuant hereto and any and all amendments, modifications, and
      supplements thereto, including, without limitation, the costs and fees of
      Lender's legal counsel and any taxes or expenses associated with or incurred
      in
      connection with any instrument or agreement referred to herein or contemplated
      hereby.

    

    7. The
      effectiveness of the amendments to the Loan Agreement set forth in this
      Amendment is subject to the satisfaction of each of the following conditions
      precedent, in each case in form and substance satisfactory to
      Lender:

    

    (a) Lender
      shall have received duly executed and delivered counterparts of this Amendment
      from Borrower and Guarantor;

    

    (b) Lender
      shall have received full payment of the Amendment Fee; and

    

    (c) no
      Default or Event of Default shall exist or occur on the date

    8. Upon
      the
      effectiveness of this Amendment, each reference in the Loan Agreement to "this
      Agreement," "hereunder," or words of like import shall mean and be a reference
      to the Loan Agreement, as amended by this Amendment.

    

    9. This
      Amendment shall be binding upon and inure to the benefit of the parties hereto
      and their respective successors and assigns.

    10. This
      Amendment shall be governed by and construed in accordance with the internal
      laws of the State of Florida, without giving effect to its conflict of laws
      principles.

    

    11. Except
      as
      otherwise expressly provided in this Amendment, nothing herein shall be deemed
      to amend or modify any provision of the Loan Agreement or any of the other
      Financing Agreements, each of which shall remain in full force and effect.
      This
      Amendment is not intended to be, nor shall it be construed to create, a novation
      or accord and satisfaction, and the Loan Agreement as herein modified shall
      continue in full force and effect.

    

    12. This
      Amendment may be executed in any number of counterparts and by different parties
      to this Amendment on separate counterparts, each of which, when so executed,
      shall be deemed an original, but all such counterparts shall constitute one
      and
      the same agreement. Any manually-executed signature page delivered by a party
      by
      facsimile or other electronic transmission shall be deemed to be an original
      signature page hereto. Any party delivering a manually-executed counterpart
      of
      this Amendment by facsimile or other electronic transmission shall also deliver
      an original executed counterpart of this Amendment, but the failure to deliver
      an original executed counterpart shall not affect the validity, enforceability
      and binding effect of this Amendment.

    

    13. To
      induce Lender to enter into this Amendment and to grant the accommodations
      set
      forth herein, Borrower
      hereby releases and forever discharges Lender and each and every one of its
      directors, officers, employees, representatives, legal counsel, agents, parents,
      subsidiaries and affiliates, and persons employed or engaged by them, whether
      past or present (hereinafter collectively referred to as the "Lender
      Releasees"), of and from all actions, agreements, damages, judgments, claims,
      counterclaims, and demands whatsoever, whether liquidated or unliquidated,
      contingent or fixed, determined or undetermined, at law or in equity, which
      Borrower had, now has, or may at any time have against the Lender Releasees,
      or
      any of them, for, upon or by reason of any matter, cause or thing whatsoever
      to
      the date of this Amendment, whether arising out of, related to or pertaining
      to
      the Obligations, the Financing Agreements or otherwise, including, without
      limitation, the negotiation, closing, administration and funding of the
      Obligations or the Financing Agreements. Borrower acknowledges that this
      provision is a material inducement for Lender entering into this Amendment
      and
      that this provision shall survive the payment in full of all Obligations and
      the
      termination of all Financing Agreements.
